Effect of DU meridian long snake moxibustion on intestinal flora of people with yang deficiency

BackgroundThe changes of intestinal flora are closely related to the occurrence and development of many diseases. Long snake moxibustion has the functions of strengthening the body resistance, eliminating pathogenic factors and balancing yin and yang, and has been widely used in clinic. This study aimed to explore the effect of long snake moxibustion on intestinal flora in people with yang deficiency constitution. MethodsThe 60 subjects with yang deficiency constitution recruited in a tertiary A-level-integrated traditional Chinese medicine hospital were randomly divided into Du meridian group and non-Du meridian group between May 1, 2021, and July 31, 2021, which were treated once a week for 12 consecutive times. The scores of symptoms of yang deficiency were recorded before and after treatment, fresh stool samples were collected, and the distribution of intestinalflora was detected by 16 S rDNA sequencing technology. ResultsCompared with before treatment, the scores of symptoms of yang deficiency in both groups had a distinct decrease after treatment (P<0.05), and the effect of Du meridian group was better than that of non-Du meridian group. After treatment, the Du meridian group was superior to the non-Du meridian treatment group in the diversity of intestinal flora, the relative abundance of phylum and genus, and the dominant intestinal flora. ConclusionsLong snake moxibustion on Du meridian can improve the diversity of intestinal flora, promote the balance between beneficial bacteria and harmful bacteria, enhance the integrity of intestinal epithelial barrier and regulate intestinal immunity, thus improving Yang deficiency constitution.

Host cells reprogram lipid droplet synthesis through YY1 to resist PRRSV infection.

Metabolism in host cells can be modulated after viral infection, favoring viral survival or clearance. Here, we report that lipid droplet (LD) synthesis in host cells can be modulated by yin yang 1 (YY1) after porcine reproductive and respiratory syndrome virus (PRRSV) infection, resulting in active antiviral activity. As a ubiquitously distributed transcription factor, there was increased expression of YY1 upon PRRSV infection both in vitro and in vivo. YY1 silencing promoted the replication of PRRSV, whereas YY1 overexpression inhibited PRRSV replication. PRRSV infection led to a marked increase in LDs, while YY1 knockout inhibited LD synthesis, and YY1 overexpression enhanced LD accumulation, indicating that YY1 reprograms PRRSV infection-induced intracellular LD synthesis. We also showed that the viral components do not colocalize with LDs during PRRSV infection, and the effect of exogenously induced LD synthesis on PRRSV replication is nearly lethal. Moreover, we demonstrated that YY1 affects the synthesis of LDs by regulating the expression of lipid metabolism genes. YY1 negatively regulates the expression of fatty acid synthase (FASN) to weaken the fatty acid synthesis pathway and positively regulates the expression of peroxisome proliferator-activated receptor gamma (PPARγ) to promote the synthesis of LDs, thus inhibiting PRRSV replication. These novel findings indicate that YY1 plays a crucial role in regulating PRRSV replication by reprogramming LD synthesis. Therefore, our study provides a novel mechanism of host resistance to PRRSV and suggests potential new antiviral strategies against PRRSV infection.IMPORTANCEPorcine reproductive and respiratory virus (PRRSV) has caused incalculable economic damage to the global pig industry since it was first discovered in the 1980s. However, conventional vaccines do not provide satisfactory protection. It is well known that viruses are parasitic pathogens, and the completion of their replication life cycle is highly dependent on host cells. A better understanding of host resistance to PRRSV infection is essential for developing safe and effective strategies to control PRRSV. Here, we report a crucial host antiviral molecule, yin yang 1 (YY1), which is induced to be expressed upon PRRSV infection and subsequently inhibits virus replication by reprogramming lipid droplet (LD) synthesis through transcriptional regulation. Our work provides a novel antiviral mechanism against PRRSV infection and suggests that targeting YY1 could be a new strategy for controlling PRRSV.

Coronary heart disease: innovative understanding from traditional Chinese medicine and treatment by classic formulas

Coronary heart disease is a common cardiovascular disease, attacking about 11.4 million patients in China. With increasing prevalence and mortality year by year, coronary heart disease has become a major factor threatening human health and public health. Although primary and secondary prevention, intervention, coronary artery bypass grafting and other interventions have reduced the death rate, there are drug(aspirin) resistance, secondary nitroglycerin failure, post-intervention fatigue, chest tightness, and an-xiety, and complication with a high risk of bleeding, which have become the key clinical and scientific issues needed to be resolved. Coronary heart disease belongs to the category of chest impediment and heart pain in traditional Chinese medicine(TCM). The TCM etiology of this disease includes external contraction of cold, emotional disorders, constitutional insufficiency, physical weakness, and labor injury, which are closely related to sympathetic nerve activity, state of cardiac and psychological diseases, family history, and cardiovascular metabolic disorders in modern medicine. The TCM causes of coronary heart disease include Qi depression, phlegm turbidity, blood stasis, fire-heat, cold congealing, and healthy Qi deficiency, which are associated with emotional factors such as anxiety and depression, abnormal lipid metabolism, abnormalities in blood circulation and coagulation, inflammatory responses, hyperactive immune responses, and heart failure, chronic wasting disease, or aging, respectively. Accordingly, the patients with Qi depression should be treated with Chaihu Longgu Muli Decoction, and those with phlegm turbidity should be treated with Wendan Decoction and Gualou Xiebai Banxia Decoction. Xuefu Zhuyu Decoction and Guizhi Fuling Pills are recommended for blood stasis, Xiaoxianxiong Decoction and Sanhuang Xiexin Decoction for fire-heat, Zhishi Xiebai Guizhi Decoction for cold congealing, and Renshen Decoction for healthy Qi deficiency. Due to the changes in the spectrum of diseases from ancient to modern times as well as the differences in physical constitution, the key cause of coronary heart disease has evolved from the chest Yang deficiency and cold congealing to Qi depression, phlegm turbidity, phlegm combined with stasis, and fire-heat, showing a shift from cold to heat and from deficiency to excess. The combination of classic formulas presents a pattern. That is, the core formula-syndrome correspondence of a disease often fixedly appears with other formula-syndrome correspondence, which may be related to the development of the pathophysiological mechanism of the disease. In the clinical application of modern pharmacological results, the research team has formulated the clinical principle of pathogenesis corresponding to pathological changes and medicinal nature corresponding pharmacological effects. The modern pharmacological research on classic formulas is conducive to targeted treatment. Moreover, classic formulas help to ameliorate aspirin resistance, clopidogrel resistance, post-intervention anxiety, and high risk of bleeding and address the lack of effective blockade of critical lesions in the coronary artery and the progression of post-infarction heart failure. The innovative understanding of the etiology and pathogenesis of co-ronary heart disease helps to improve the clinical efficacy of TCM and the clinical system for treating coronary heart disease with classic formulas.

WITHDRAWN: Research on Traditional Chinese Medicine Syndrome Animal Models and Multi-omics Biomarkers in Type II Diabetes: A Review

IntroductionDiabetes, a chronic metabolic disease marked by hyperglycemia, predominantly manifests as Type 2 Diabetes Mellitus (T2DM), representing over 90% of diabetes cases with intricate pathogenesis and varied pathological attributes. Drawing upon Traditional Chinese Medicine (TCM) principles, this article outlines the methodology and evaluation criteria for integrating TCM syndromes into animal models for T2DM while comprehensively examining T2DM pathogenic mechanisms and physiological characteristics from various omics perspectives to pinpoint essential biomarkers. MethodsResearchers conducted comprehensive searches using databases such as Web of Science, Google Scholar, Baidu Scholar and CNKI. Selection criteria were based on content relevance and publication date, resulting in the inclusion of 223 articles, including Chinese and English journal papers, master's and doctoral theses. This comprehensive review aims to highlight the importance of TCM in research related to T2DM, as well as its compatibility with modern technology, providing guidance for future development of targeted drugs and clinical treatment for T2DM. ResultsThis article, based on the fundamental theories of Traditional Chinese Medicine, summarized the methodology and evaluation criteria for constructing 6 types of T2DM animal models: Blood Stasis Syndrome, Kidney Yin Deficiency Syndrome, Spleen Deficiency Syndrome, Yang Deficiency Syndrome, Qi and Yin Deficiency Syndrome, and Yin and Yang Deficiency Syndrome. It comprehensively analyzed the latest research progress on the pathogenic mechanisms and physiological characteristics of T2DM from the perspectives of genomics, proteomics, transcriptomics, metabolomics, and gut microbiomics, providing crucial insights for the discovery of potential biomarkers for T2DM. DiscussionsThe broad use of multi-omics tech aids in T2DM pathogenesis understanding. For comprehensive insight, analyzing genes, proteins, metabolites and microbiota is vital. As a metabolic disorder, T2DM has a prolonged development process, necessitating the selection of different biomarkers for various stages of the disease progression and long-term monitoring of the overall changes in key biomarkers. The development of a “disease-syndrome” animal model is pivotal for the advancement of targeted drug therapies. The crux lies in the accuracy, repeatability, and stability of the model and its assessment criteria. Future investigations should focus on multi-omics analyses across diverse T2DM syndromes to facilitate personalized treatment strategies.

Distribution of Traditional Chinese Medicine syndromes in diabetic kidney disease chronic kidney disease 1-5: a correlation study.

To analyze the distribution of Traditional Chinese medicine (TCM) syndromes in patients with diabetic kidney disease (DKD) and its related factors. We enrolled 435 patients with DKD, who were not undergoing dialysis, admitted to the Department of Nephrology, First Medical Center, Chinese PLA General Hospital from April 2020 to August 2021. Analysis of their TCM syndromes and related factors was carried out. The 435 patients included 109, 117, 86, and 123 chronic kidney disease (CKD) 1-2, CKD3, CKD4, and CKD5 cases, respectively. With the progression of CKD1-5, the proportion of Yin deficiency and dry heat syndrome, and that of Qi and Yin deficiency syndrome showed a downward trend, whereas the proportion of spleen-kidney Yang deficiency, blood deficiency, blood stasis, water stagnation, and phlegm turbidity syndromes showed an upward trend; the differences were statistically significant (P < 0.05). Multivariate logistic regression analysis showed that Yin deficiency and dry heat syndrome was positively correlated with hemoglobin [odds ratio (OR) = 1.022, P = 0.005], albumin (OR = 1.058, P = 0.006), and estimated glomerular filtration rate (eGFR) (OR = 1.020, P < 0.001) but negatively correlated with male sex (OR = 0.277, P = 0.004). Qi and Yin deficiency syndrome was positively correlated with albumin (OR = 1.056, P < 0.001) and eGFR (OR = 1.008, P = 0.022) but negatively correlated with age (OR = 0.977, P = 0.023). Liver-kidney Yin deficiency syndrome was positively correlated with age (OR = 1.028, P = 0.021) and glycosylated hemoglobin (OR = 1.223, P = 0.007) but negatively correlated with total cholesterol (OR = 0.792, P = 0.006). Spleen-kidney Yang deficiency syndrome was negatively correlated with hemoglobin (OR = 0.977, P < 0.001), albumin (OR = 0.891, P < 0.001), and eGFR (OR = 0.978, P < 0.001) but positively correlated with high density lipoprotein (OR = 3.376, P = 0.001). With CKD1-5 progression, TCM syndromes changed from Yin deficiency and dry heat syndrome to syndrome of deficiency of both Qi and Yin, liver-kidney Yin, and spleen-kidney Yang deficiency syndromes. TCM syndromes were correlated with laboratory test results.

Material basis of kidney Yang deficiency rats before and after salt processing of Dipsacus asper based on spectrum-effect relationship

This paper aims to study the spectrum-effect relationship between the fingerprints before and after salt processing of Dipsacus asper and the efficacy of warming and tonifying kidney Yang and find the main active components against kidney Yang deficiency before and after salt processing of D. asper, so as to provide the basis for clarifying the effect of salt processing on kidney Yang deficiency. The HPLC fingerprint before and after salt processing of D. asper was established by the HPLC-DAD. 15 common peaks were obtained, and 11 components were identified. The content changes of various components in rat serum were detected, and the difference in efficacy before and after salt processing was compared. The results of pharmacological experiments showed that salt processing of D. asper could enhance the kidney index. At the same dose, there was a significant difference between the raw D. asper and D. asper after salt processing groups. Compared with the model group, the contents of ACTH, cAMP, CORT, E_2, GH, Na~+-K~+-ATPase, T, and T4 in the serum of rats in the administration group increased to a certain extent, and the contents of cGMP and TNF-α decreased to a certain extent. Among them, there were significant differences in the above indexes in the serum of rats in the high-dose group of raw D. asper, middle-dose group of D. asper after salt processing, high-dose group of D. asper after salt processing, and the positive drug group. The overall results showed that D. asper after salt processing was more effective than raw D. asper in preventing kidney yang deficiency. The efficacy of D. asper was evaluated by grey correlation analysis, entropy method, and Pearson correlation analysis, and the components of D. asper after salt processing against kidney yang deficiency were screened out. According to the results of correlation degree ranking, the components with increased ranking before and after salt processing of D. asper were loganin, chlorogenic acid, dipsacoside A, asperosaponin Ⅵ, caffeic acid, and isochlorogenic acid B. It was preliminarily speculated that these compounds may be the potential pharmacodynamic components for the treatment of kidney yang deficiency before and after salt processing of D. asper. The changing components before and after the salt processing of D. asper were determined, which proved that D. asper after salt processing was superior to D. asper in the treatment of kidney yang deficiency. The spectrum-effect relationship between the efficacy of D. asper before and after salt processing and the treatment of kidney yang deficiency was established, which laid a foundation for the subsequent study on the pharmacodynamic components and molecular mechanism of salt processing of D. asper.

Paradoxical behavior toward innovation: Knowledge sharing, knowledge hiding, and career sustainability interactions

The COVID-19 pandemic has accelerated advance of digital technologies, resulting in unconventional innovation challenges for companies and novel, digital-based types of gig workers. Considering this phenomenon and its huge impact on employees' career development patterns and innovative work behavior (IWB), this research investigates how gig workers' perceived career sustainability affects their post-pandemic IWB. A critical feature of gig work is breaking traditional boundaries of working time and space, which often causes paradoxes disrupting traditional modes of knowledge exchange at work. Accordingly, this study is anchored theoretically in an exploration of how interacting mechanisms caused by two primary knowledge exchange behaviors, knowledge sharing and knowledge hiding, affect employee IWB from a paradoxical perspective of yin–yang harmonizing. Data from quantitative and qualitative studies were collected from China's cross-border e-commerce enterprises, which mainly target North American and European markets. The results indicate a nonlinear relationship between career sustainability and IWB. The interaction of knowledge sharing and knowledge hiding relates significantly to IWB, with the interaction moderating the U-shaped career sustainability–IWB relationship that was detected. Our study also carries valuable theoretical and practical implications that indicate that job flexibility and information and communications technology (ICT) can favor knowledge exchange, through knowledge sharing and knowledge hiding interaction, in proportion to the degree of career sustainability. The study also suggests a need to adopt organizational sharing strategies capable of spreading a work culture based on results, in which global companies can confront perplexing employment situations more effectively, thus promoting innovation.

Integrated serum pharmacochemistry, network pharmacology, and pharmacokinetics to clarify the effective components and pharmacological mechanisms of the proprietary Chinese medicine Jinkui Shenqi Pill in treating kidney yang deficiency syndrome

The proprietary Chinese medicine Jinkui Shenqi Pill (PCM-JKSQP) is a classic compound used for the effective clinical treatment of kidney yang deficiency syndrome (KYDS), a metabolic disease accompanied by kidney injury. However, its active ingredients and therapeutic mechanisms are not clear. This study employed serum pharmacochemistry, network pharmacology, and pharmacokinetics (PK) to identify the bioactive components of PCM-JKSQP and preliminarily clarify its mechanism in treating KYDS. One hundred and forty chemical components of PCM-JKSQP, 47 (20 parent compouds and 27 metabolites) of which were absorbed into the blood, were identified by ultra-high-performance liquid chromatography-quadrupole-orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS). The topological parameters of network pharmacology and high concentrations in blood found six parent components as PK markers (cinnamic acid, paeonol, loganin, morroniside, apigenin, and poricoic acid A). PK analysis further identified these six compounds as active ingredients. Protein-protein interaction (PPI) analysis and molecular docking simulation predicted and verified eight core targets (TP53, ESR1, CTNNB1, EP300, EGFR, AKT1, ERBB2, and TNF). Most were concentrated in the MAPK, HIF-1, and PI3K-AKT signaling pathways, indicating that these six active ingredients may mainly exert therapeutic effects through these three pathways via their core targets. The PK results also showed these six components were absorbed quickly, although cinnamic acid and paeonol were rapidly metabolized, with a short half-life and retention time. Loganin and morroniside did not have high peak concentrations, and apigenin and poricoic acid A had long retention times. This study provides a new overall perspective for exploring the bioactive components and mechanisms underlying the effects of PCM-JKSQP in treating KYDS.

YAP/TAZ activation mediates PQ-induced lung fibrosis by sustaining senescent pulmonary epithelial cells.

Paraquat (PQ) is a widely used herbicide and a common cause of poisoning that leads to pulmonary fibrosis with a high mortality rate. However, the underlying mechanisms of PQ-induced pulmonary fibrosis and whether pulmonary epithelial cell senescence is involved in the process remain elusive. In this study, PQ-induced pulmonary epithelial cell senescence and Hippo-YAP/TAZ activation were observed in both C57BL/6 mice and human epithelial cells. PQ-induced senescent pulmonary epithelial cells promoted lung fibroblast transformation through secreting senescence-associated secretory phenotype (SASP) factors. Yap/Taz knockdown in mice lungs significantly decreased the expression of downstream profibrotic protein Ctgf and senescent markers p16 and p21, and alleviated PQ-induced pulmonary fibrosis. Interfering YAP/TAZ in senescent human pulmonary epithelial cells resulted in decreased expression of the anti-apoptosis protein survivin and elevated level of apoptosis. In conclusion, our findings reveal a novel mechanism by which the involvement of Hippo-YAP/TAZ activation in pulmonary epithelial cell senescence mediates the pathogenesis of PQ-induced pulmonary fibrosis, thereby offering novel insights and potential targets for the clinical management of PQ poisoning as well as providing the mechanistic insight of the involvement of Yap/Taz activation in cell senescence in pulmonary fibrosis and its related pulmonary disorders. The YIN YANG balance between cell senescence and apoptosis is important to maintain the homeostasis of the lung, the disruption of which will lead to disease.

The higher odds of depression were observed in Qi stagnation constitution (p &lt; 0.001, OR = 5.787, 95%CI: 3.275 – 10.227), Qi deficiency constitution (p &lt; 0.001, OR = 4.369, 95%CI: 2.643 – 7.222), Yang deficiency constitution (p &lt; 0.001, OR = 3.682, 95%CI: 2.097 – 6.277), Gender (p &lt; 0.001, OR = 3.451, 95%CI: 1.980 – 6.017), Dampness-heat constitution (p &lt; 0.001, OR = 2.534, 95%CI: 1.545 – 4.156), Inherited-special constitution (p = 0.003, OR = 2.160, 95%CI: 1.302 – 3.584) and Yin deficiency constitution (p = 0.028, OR = 1.771, 95%CI: 1.064 – 2.948). Conclusion: This study indicated the distributions of TM body constitutions and the factors associated with depression among elderly inpatients in Traditional Medicine Hospital of Thua Thien Hue. Therefore, the assessment of the TM body constitutions contributes to the prevention strategy and early detection of depression in the health facilities as well as in the community.

Efficacy and Mechanism of Fuyang Yiyin Method in Pulmonary Fibrosis Based on the Theory of Yang Transforming into Qi, Yin Constituting Form

Idiopathic pulmonary fibrosis (IPF) is a common pathological manifestation of various pulmonary diseases, characterized by insidious onset and progression to irreversible organ failure. Currently, there are still inadequacies in the diagnosis and treatment of IPF. Traditional Chinese medicine (TCM) can intervene in IPF at multiple levels, targets, and pathways, possessing significant advantages in the treatment of IPF. The underlying mechanisms deserve further exploration. The theory of Yang Transforming into Qi, Yin Constituting Form in Huangdi Neijing embodies the specific meanings of yin and yang, containing profound views on life and disease. The pathological changes of IPF conform to the theory of yin and yang in Yang Transforming into Qi, Yin Constituting Form, where deficiency of yang transforming into qi and excessive formation of yin constitute the core pathogenesis of IPF. This paper proposes the principle of Fuyang Yiyin for IPF, aiming to nourish the source of fire and dispel yin turbidity, in order to broaden the clinical treatment strategies for IPF.

Rules of prescriptions for heart failure of dilated cardiomyopathy based on latent structure model and association rules

The latent structure model and association rules analysis were employed to explore the compatibility rules of prescriptions for heart failure of dilated cardiomyopathy, with a view to providing theoretical support for the clinical treatment of this disease based on syndrome differentiation and the formulation of guidelines. The articles about the treatment of heart failure of dilated cardiomyopathy were retrieved from CNKI, Wanfang, VIP, and SinoMed. The database was established in Microsoft Excel 2019. Lantern 5.0 and Rstudio were used to analyze the latent structure and association rules of Chinese medicine with the frequency greater than 4.00%. Furthermore, the frequency structure model was used to mine the rules of prescriptions for heart failure of dilated cardiomyopathy. The study included 175 traditional Chinese medicine(TCM) prescriptions, involving 128 Chinese medicines, with the cumulative frequency of 1 847. High-frequency medicines included Astragali Radix, Salviae Miltiorrhizae Radix et Rhizoma, Poria, Cinnamomi Ramulus, Glycyrrhizae Radix et Rhizoma, with the main effects of tonifying, activating blood, resolving stasis, and releasing exterior. A total of 17 hidden variables, 34 hidden categories, and 6 comprehensive cluster models, along with 15 core prescriptions, were obtained. According to the prescriptions, the patients mainly had the syndromes of heart-Yang and Qi deficiency, Qi deficiency and blood stasis, heart-kidney Yang deficiency or Qi-Yin deficiency. Fifty-four strong association rules were obtained through association rule analysis. The highest degree of support was observed for the combination of Salviae Miltiorrhizae Radix et Rhizoma-Astragali Radix, while the highest degree of confidence was found for the combination of Salviae Miltiorrhizae Radix et Rhizoma-Cinnamomi Ramulus-Ophiopogonis Radix-Astragali Radix. The heart failure of dilated cardiomyopathy, characterized by internal deficiency and excess manifestations, is attributed to deficiency, stasis, and water. These factors are closely associated with the heart, lung, and spleen. The treatment should follow the principle of invigorating Qi and warming Yang, and meanwhile the method of activating blood and resolve stasis or moving Qi and promoting urination can be adopted according to the specific syndrome of patients.

The chemometrics analysis and integrated pharmacology approach to decipher the effect and mechanism between raw and processed cistanche tubulosa

Ethnopharmacological relevanceCistanche tubulosa (CT) is the dried fleshy stem with scaly leaves of Cistanche tubiflora (Schenk) Wight, which has the effects of tonifying the kidney-yang, benefiting the vital essence and blood, and moisturizing the intestines and laxatives. There are differences in the activity of CT before and after processing, but the mechanism of processing is not clear. Aim of the studyThe study aimed to compare the strength of action of CT before and after yellow-wine processing in the treatment of constipation and kidney yang deficiency and to identify the active ingredients responsible for the differences in activity before and after yellow-wine processing. Materials and methodsThis study established the fingerprints of CT and PCT using HPLC to identify their shared components. Then efficacy of KYDS and FC were carried out to compare the differences between CT and PCT in terms of efficacy. Next, this study established the spectrum-effect relationship between the shared chemical components and the medical effects of CT and PCT using the gray correlation analysis and entropy methods. Ultimately, the activity of the analyzed chemical components was verified using the zebrafish model. ResultsCT was more effective than PCT in promoting intestinal peristalsis, regulating gastrointestinal hormone levels, and thus treating FC. PCT was more effective than CT in improving the level of hormone indexes of the hypothalamus-pituitary-target gland axis, replenishing blood, and enhancing immunity. Through the analysis of the spectrum-effect relationship, it was finally found that 5, 6, 12 (tubuloside A), and 13 (isoacteoside) might be more closely related to the activity of tonifying kidney yang, and peaks 9, 10, and 11 (acteoside) are more closely associated with the treatment of constipation, and peaks 3 (salidroside), 4, 1, 2 (geniposidic acid), and 8 (echinacoside) were associated with both kidney yang tonic and treatment of constipation. At the same time, an activity verification experiment showed that echinacoside, geniposidic acid, and salidroside were effective in the treatment of FC and KYDS, while acteoside was very effective in the treatment of FC, and tubuloside A was significant in supplementing the blood, which validated the spectrum-effect relationship analysis. ConclusionThis study proved that the raw CT had a better laxative effect, while the yellow-wine processed CT had a better kidney-yang tonic effect; moreover, spectrum-effect relationships were established to analyze the chemical components leading to changes in the activity of CT before and after yellow-wine processing.

CHEN Rixin's clinical experience of heat-sensitive moxibustion for Wenyang Yangshen in treatment of insomnia of yang deficiency.

The paper introduces CHEN Rixin's experience and ideas of heat-sensitive moxibustion for Wenyang Yangshen (warming-up yang and nourishing the spirit) in treatment of insomnia of yang deficiency. This type of insomnia is caused by yang insufficiency of the body and malnutrition of the spirit. The treatment focuses on Wenyang Yangshen. Replenishing yang (Shenque [CV 8], Qihai [CV 6] and Guanyuan [CV 4]) is combined with promoting yang circulation (Taiyang [EX-HN 5]). The acupoint combination is optimized through identifying the heat sensitivity. Sparrow-pecking moxibustion and mild moxibustion are used to control the appropriate moxibustion temperature, efficiently stimulate deqi and individually saturate the dose of moxibustion so as to target the principle of treatment and improve the sleep quality.

The acute toxic effect of Chinese medicine Fuzi is exacerbated in kidney yang deficiency mice due to metabolic difference

Ethnopharmacological relevanceThe proper application of toxic medicines is one of the characteristics of traditional Chinese medicines, and the use of traditional Chinese medicines follows the principle of dialectical treatment. It is necessary to combine different “syndrome” or “disease” states with the toxicity of traditional Chinese medicines to form a reliable toxicity evaluation system. Fuzi, the lateral root of Aconitum carmichaelii Debx, is recognized as a panacea for kidney yang deficiency syndrome, however, its toxic effects significantly limit its clinical application. Aim of the studyHerein, our research aimed to explore the toxic effects of Fuzi on syndrome models, and tried to reveal the underlying mechanisms. Materials and methodsFirstly, the mouse model of kidney yang deficiency syndrome was established through intramuscular injection of 25 mg/kg hydrocortisone per day for 10 consecutive days. Then, the acute toxicity of Fuzi in normal mice and kidney yang deficiency model mice was explored. Finally, the plasma metabolite concentrations and liver CYP3A4 enzyme activity were analyzed to reveal the possible mechanisms of the different pharmacological and toxicological effects of Fuzi in individuals with different physical constitutions. ResultsIt was found that the treatment with Fuzi (138 g/kg) had serious toxic effects on kidney yang deficiency mice, leading to the death of 80% of the mice, whereas it showed no lethal toxicity in normal mice. This indicates that Fuzi induced greater toxicity in kidney yang deficiency mice than in normal ones. The liver CYP3A4 enzyme activity in kidney yang deficiency mice was decreased by 20% compared to the controls, resulting in slower metabolism of the toxic diester diterpenoid alkaloids in Fuzi. ConclusionIn conclusion, our study showed that changes of the metabolic enzyme activity in individuals with different syndromes led to different toxic effects of Chinese medicines, emphasizing the crucial importance of considering individual physical syndromes in the clinical application of traditional Chinese medicine, and the significance of conducting safety evaluations and dose predictions on animal models with specific syndromes for traditional Chinese medicines.

Anti-miR-141-3p maintains homeostasis between autophagy and apoptosis by targeting Yy1 in the fetal lumbosacral defecation center of rats

Anorectal malformations are congenital diseases that lead to postoperative fecal incontinence, constipation, and soiling despite improvements in surgery; however, their pathological mechanisms remain unclear. Here, we report the role of microRNA-141-3p in maintaining homeostasis between apoptosis and autophagy in the lumbosacral defecation center of fetal rats with anorectal malformations. Elevated microRNA-141-3p expression inhibited Yin Yang 1 expression by binding its 3′-untranslated region, and repressed autophagy and triggered apoptosis simultaneously. Then adenylate cyclase 3 was screened to be the downstream target gene of yin yang 1 by chromatin-immunoprecipitation-sequencing experiments and yin yang 1 could positively activate the transcription of adenylate cyclase 3 by directly interacting with the motif GAGATGG and ATGG in its promoter. Intra-amniotic microinjection of adeno-rno-microRNA-141-3p-sponge-green fluorescent protein in fetal rats with anorectal malformations on embryonic day 15 restored apoptosis–autophagy homeostasis. These findings reveal that microRNA-141-3p upregulation impaired homeostasis between apoptosis and autophagy by inhibiting the yin yang 1/adenylate cyclase 3 axis, and that intra-amniotic injection of anti-microRNA-141-3p helped maintain homeostasis in the lumbosacral defecation center of anorectal malformations during embryogenesis.

Retrospective cross-sectional survey of clinical characteristics and syndrome elements distribution at different stages of coronary heart disease

The clinical data of coronary heart disease(CHD) patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine and Shenzhen Hospital of Integrated Traditional Chinese and Western Medicine from January 2022 to March 2023 were retrospectively collected. This study involved the descriptive analysis of demographic characteristics, clinical symptoms, and tongue and pulse features. The χ~2 test was conducted to analyze the distribution of syndrome elements and their combinations at diffe-rent stages of CHD, so as to reveal the clinical characteristics and syndrome patterns at various pathological stages of CHD. This study extracted 28 symptom entries, 10 tongue manifestation entries, and 7 pulse manifestation entries, summarized the 5 main disease locations of the heart, lung, liver, spleen, and kidney, and the 8 main disease natures of blood stasis, phlegm turbidity, Qi stagnation, heat(fire), fluid retention, Qi deficiency, Yin deficiency, and Yang deficiency and 8 combinations of disease natures. The χ~2 test showed significant differences in the distribution of syndrome elements including the lung, liver, spleen, kidney, blood stasis, heat(fire), Qi stagnation, heat syndrome, water retention, Qi deficiency, Yin deficiency, and Yang deficiency between different disease stages. Specifically, the liver, blood stasis, heat(fire), and Qi stagnation accounted for the highest proportion during unstable stage, and the lung, spleen, kidney, water retention, Qi deficiency, Yin deficiency, and Yang deficiency accounted for the highest proportion at the end stage. The distribution of Qi deficiency varied in the different time periods after percutaneous coronary intervention(PCI). As shown by the χ~2 test of the syndrome elements combination, the distribution of single disease location, multiple disease locations, single disease nature, double disease natures, multiple natures, excess syndrome, and mixture of deficiency and excess varied significantly at different stages of CHD. Specifically, single disease location, single disease nature, and excess syndrome accounted for the highest proportion during the stable stage, and double disease natures accounted for the highest proportion during the unstable stage. Multiple disease locations, multiple disease natures, and mixture of deficiency and excess accounted for the highest proportion during the end stage. In conclusion, phlegm turbidity and blood stasis were equally serious during the stable stage, and a pathological mechanism caused by blood stasis and toxin existed during the unstable stage. The overall Qi deficiency worsened after PCI, and the end stage was accompanied by the Yin and Yang damage and the aggravation of water retention. There were significant differences in the distribution of clinical characteristics and syndrome elements at different stages of CHD. The pathological process of CHD witnessed the growth and decline of deficiency and excess and the combination of phlegm turbidity and blood stasis, which constituted the basic pathogenesis.

After automation: Homelessness prioritization algorithms and the future of care labor

People experiencing homelessness seek support from homeless services systems that increasingly rely on prioritization algorithms to determine who is the most deserving of scarce resources. In this paper, we argue that algorithmic harms in homeless services require a reparative approach that takes the data work of care workers seriously. Building on Davis, Williams, and Yang's concept of algorithmic reparation, we present a qualitative study that examines the intertwining of data work and care labor of 15 care workers. We show how they wrestle with the ethics of algorithmic prioritization and develop workarounds that allow them to advocate for their clients. We contribute an empirical understanding of how care workers provide care under homeless services systems that equate data work with care labor to justify work intensification. Our findings have implications for understanding the future of care labor in datafied conditions and the social and political ramifications of algorithmically mediated care.

Wenyang-Tianjing-Jieyu Decoction Improves Depression Rats of Kidney Yang Deficiency Pattern by Regulating T Cell Homeostasis and Inflammation Level.

Chronic inflammation is one of the key mechanisms of depression. Wenyang-Tianjin-Jie Decoction (WTJD) is an effective antidepressant found in the course of diagnosis and treatment, but the mechanism of therapeutic effect is not clear. The study aimed to evaluate the efficacy of WTJD in the kidney yang deficiency (KYD) type of depression rats and reveal its mechanisms. We selected forty 6-week-old male Sprague-Dawley rats for the study. We established a KYD [Phellodendron amurense Rupr (Huangbai) solution oral gavage and 4°C environments; 8 weeks] type of depression (chronic unpredictable mild stimulus; 6 weeks) rat model first. After successful modeling, we used WTJD or fluoxetine on rats for 3 weeks. Then we evaluated the depression and KYD behavior. Finally, we observed the expression of key inflammatory factors and proteins in peripheral blood and hippocampus, and further investigated the immune balance of Th17/Treg and Th1/Th2 cells and the activity of their main regulatory pathways JAK2/STAT3 and TLR4/TRAF6/NF-κB. The imbalance of Th17/Treg and Th1/Th2 cells in rats were related to KYD and depressive symptoms. Through this study, we found that WTJD can inhibit the activity of JAK2/STAT3 and TLR4/TRAF6/NF-κB pathways, balance Th17/Treg and Th1/Th2 cell homeostasis, regulate the levels of inflammatory factors in the hippocampus and peripheral blood, and reverse KYD and depression. This study confirmed that WTJD had a reliable effect on depression rats with KYD, and its mechanism was to regulate the immune homeostasis of hippocampal T cells and related inflammatory factors to improve KYD and depression symptoms in rats.

Study on the intervention effect of Epimedium before and after suet-oil-processed on kidney yang deficiency rats based on intestinal flora and fecal metabolomics

Epimedium is a Chinese herbal medicine commonly used in clinical practice to reinforce yang. Previous studies have shown that Epimedium fried with suet oil based has the best effect on warming kidney and promoting yang. Evidence suggests a relationship between kidney yang deficiency syndrome (KYDS) and metabolic disorders of the intestinal microflora. However, the specific interaction between KYDS and the intestinal microbiome, as well as the internal regulatory mechanism of the KYDS intestinal microbiome regulated by Epimedium fried with suet oil, remain unclear. The purpose of this study was to investigate the regulatory effects of different processed products of Epimedium on intestinal microflora and metabolites in rats with kidney yang deficiency, and to reveal the processing mechanism of Epimedium fried with suet oil warming kidney and helping yang. 16S rRNA and LC-MS/MS technology were used to detect fecal samples. Combined with multivariate statistical analysis, differential intestinal flora and metabolites were screened. Then the content of differential bacteria was then quantified using quantitative real-time fluorescence PCR. Furthermore, the correlation between differential bacterial flora and metabolites was analyzed using Spearman's method. The study found that the composition of intestinal flora in rats with kidney yang deficiency changed compared to healthy rats. Epimedium fried with suet oil could increase the levels of beneficial bacteria, while significantly reducing the levels of harmful bacteria. Real-time quantitative PCR results were consistent with 16S rRNA gene sequencing analysis. Fecal metabolomics revealed that KYDS was associated with 30 different metabolites, involving metabolic pathways steroid hormone biosynthesis etc. Moreover, differential bacteria were closely correlated with potential biomarkers. Epimedium could improve metabolic disorders associated with KYDS by acting on the intestinal flora, with Epimedium fried with suet oil demonstrating the most effective regulatory effect. Its potential mechanism may involve the regulation of abnormal metabolism and the impact on the diversity and structure of the intestinal flora.
