Discussion on the treatment of diabetic kidney disease based on the "gut-fat-kidney" axis.

Diabetic kidney disease is the main cause of end-stage renal disease, and its prevention and treatment are still a major clinical problem. The human intestine has a complex flora of hundreds of millions of microorganisms, and intestinal microorganisms, and their derivatives are closely related to renal inflammatory response, immune response, and material metabolism. Brown adipose tissue is the main part of adaptive thermogenesis. Recent studies have shown that activating brown fat by regulating intestinal flora has good curative effects in diabetic kidney disease-related diseases. As an emerging medical concept, the "gut-fat-kidney" axis has received increasing attention in diabetic kidney disease and related diseases. However, the specific mechanism involved needs further study. A new theoretical basis for the prevention and treatment of diabetic kidney disease is presented in this article, based on the "gut-fat-kidney" axis.

Guidelines and consensus: Jejunoileostomy for diabetes mellitus-surgical norms and expert consensus (2023 version)

Diabetes mellitus (DM) is a group of diseases characterized by high blood glucose caused by insufficient absolute or relative secretion of insulin. Once diagnosed, patients need long-term treatment with hypoglycemic drugs. Currently, the existing first-line hypoglycemic drugs do not provide effective treatment for DM and its complications. In the past, the first generation and the second generation of weight loss surgery, such as gastric bypass and sleeve gastric surgery, had strict body mass index requirements. Moreover, post-surgery, patients are prone to fluctuating hypoglycemia, gastroesophageal reflux, and dumping syndrome. Hence, the curative effect of this type of surgery was compromised to a certain extent. Jejunoileostomy is a third-generation surgery for patients with DM, which has been shown to improve glucose and lipid metabolism, without changing the original gas-trointestinal tract structure. Different from previous weight loss surgeries, jejunoileostomy has been clinically observed to delay the development of DM-related complications. Additionally, the postoperative complications are mild and do not affect the patient’s quality of life. Based on our clinical observations from multi-center large samples, our team developed a consensus on the operative period and perioperative management of jejunoi-leostomy as a reference for clinical researchers.

A Systemic Review on Phytochemicals and Novel Approaches for the Management of Hepatic Cancer

Introduction: Hepatic cancer, an aggressive tumour that often develops along with cirrhosis and chronic liver disease like infections with the hepatitis B and hepatitis C viruses, while nonalcoholic steatohepatitis, is linked to metabolic syndrome or diabetes mellitus. It is the third most prevalent cause of cancer-related mortality globally and ranks fifth in cancer incidence. According to GLOBOCON, the prevalence is expected to rise by 55.0% and the fatalities by 56.4% in the near future. Objective: The present review offered natural plant-based substances and compounds having curative effects on liver cancer, along with novel drug delivery systems and nanocarrier-based therapies. Methods: The literature has been taken from PubMed, Google Scholar, SciFinder, Springer Nature, Bentham Science, PLOS one, or other internet sites. Result: Treatment for heterogeneous malignancy is multidimensional, and care guidelines differ depending on the specialty and location. Several nutritional herbal remedies and their active phytoconstituents may have an abundance of impacts on the management of liver cancer, including preventing the growth and spread of tumor cells, shielding the body from liver carcinogens, boosting the effects of chemotherapy and immunomodulating the body. Conclusion: The treatment of liver cancer involves multidisciplinary and multimodel therapy. The literature is a compilation of extract, compounds, and novel approaches like nanoparticles, microsphere, liposomes, niosomes, phytosomes and microparticles. These approaches not only manage cancer but also boost the immunity of the individuals.

Volatolomics in Fritillarias and Their Identification by Orientation Controlled cMOF Thin Film Chemiresistors

Comprehensive SummaryAs one of the famous traditional Chinese herbal medicines, Fritillariae Cirrhosae Bulbus (FCB) is widely used in the prevention and treatment of respiratory diseases and has the best curative effect among the known fritillarias medicines. Due to the variety, complex sources, similar appearance and shape, it is difficult to distinguish FCB with high curative effect (h‐FCB) from other common fritillarias (c‐FCB) in the market. In this paper, a very simple chemiresistor is used to identify FCB from three commonly used fritillarias drugs. The sensors are fabricated by anisotropic electrically conductive metal‐organic framework (cMOF) thin film Cu3(HHTP)2 (Cu‐HHTP[001] and Cu‐HHTP[100]) as active materials owing to their ability to detect specific groups of volatile organic compounds (volatolomics) as the functional motifs of chemiresistor. As a result, the sensors show orientation‐dependence identification ability to FCB. Cu‐HHTP[001]‐ based sensor shows the highest response (344.17%) to 0.5 g h‐FCB powder volatiles among its three other c‐FCB which is much higher than Cu‐HHTP[100] (135.50%). Ultimately, Cu‐HHTP[001] can realize the identification of FCB with an accuracy of 97.2% in a simple and real‐time manner.

In Vivo Efficacy of a Nanoconjugated Glycopeptide Antibiotic in Silkworm Larvae Infected by Staphylococcus aureus

To contrast the rapid spread of antibiotic resistance in bacteria, new alternative therapeutic options are urgently needed. The use of nanoparticles as carriers for clinically relevant antibiotics represents a promising solution to potentiate their efficacy. In this study, we used Bombyx mori larvae for the first time as an animal model for testing a nanoconjugated glycopeptide antibiotic (teicoplanin) against Staphylococcus aureus infection. B. mori larvae might thus replace the use of mammalian models for preclinical tests, in agreement with the European Parliament Directive 2010/63/EU. The curative effect of teicoplanin (a last resort antibiotic against Gram-positive bacterial pathogens) conjugated to iron oxide nanoparticles was assessed by monitoring the survival rate of the larvae and some immunological markers (i.e., hemocyte viability, phenoloxidase system activation, and lysozyme activity). Human physiological conditions of infection were reproduced by performing the experiments at 37 °C. In this condition, nanoconjugated teicoplanin cured the bacterial infection at the same antibiotic concentration of the free counterpart, blocking the insect immune response without causing mortality of silkworm larvae. These results demonstrate the value and robustness of the silkworm as an infection model for testing the in vivo efficacy of nanoconjugated antimicrobial molecules.

Protective Strategies for Pituitary Function During Endoscopic Transnasal Pituitary Adenoma Surgery: A Single-center Experience.

This study investigated the impact of endoscopic transnasal pituitary adenoidectomy on function and discussed the factors that contribute to postoperative pituitary function. To provide a foundation for protecting pituitary function and improving the curative effect of pituitary adenoma neuroendoscope resection. From January 2019 to January 2022, in the Neurosurgery Pituitary Tumor Diagnosis and Treatment Research Center, the First Affiliated Hospital of Shenzhen University, the clinical data of 306 patients who underwent endoscopic transnasal pituitary adenoma surgery were analyzed retrospectively. The surgical treatment strategy was discussed and explored, while the factors related to pituitary function were examined based on tumor size and Knosp grade. There were 40 cases (67.8%) of pituitary-thyroid axis, 18 cases (60%) of pituitary-adrenal axis, 25 cases (45.4%) of pituitary-gonad axis, 5 cases (62.5%) of pituitary-growth hormone axis, and 8 cases (72.7%) of diabetes insipidus with postoperative improves of hypopituitarism. Postoperative newly developed hypopituitarism occurred in 20 cases (8.1%) of pituitary-thyroid axis, 15 cases (5.4%) of pituitary-adrenal axis, 10 cases (4.0%) of pituitary-gonad axis, 5 cases (1.7%) of pituitary-growth hormone axis, and 8 cases (2.7%) of new diabetes insipidus. The incidence of pituitary-adrenal axis hypofunction in giant pituitary adenomas was significantly higher than that in microadenomas and macroadenomas (P<0.05). The incidence of hypopituitarism of Knosp grade 4 pituitary adenoma before operation was higher than that of other groups (P<0.05), but there was no significant difference in the incidence of new hypopituitarism after operation (P>0.05). In endoscopic transnasal pituitary adenoma surgery, the incidence of hypothyroidism and adrenal gland dysfunction is higher than in other hormone axes, but the recovery rate is also higher, and the recovery rate of sex hormones is lower. The incidence of postoperative hypothyroidism increases dramatically with tumor size and tumor invasiveness.

Clinical Humanistic Needs of Chinese Medicine Treatment for Patients with Chronic Urticaria from the Perspective of Narrative Medicine

Abstract: The curative effect of traditional Chinese medicine (TCM) in the treatment of chronic urticaria has gradually been recognized by the clinic, but the physical symptoms and psychological symptoms of this disease in the clinic are equal, how to play the effect of traditional Chinese medicine more effectively is worth exploring. Narrative medicine is a medical model that attaches great importance to humanistic care. There is a certain correlation between the concept of “holism of body and spirit (形神一体观)” embodied in TCM treatment of chronic urticaria and the key concepts of "narrative lock", "narrative adjustment" and "narrative intervention" in Chinese narrative medicine system. Based on the Chinese narrative medicine system, this paper connects the concept of narrative medicine with the TCM treatment of chronic urticaria, and discusses the clinical humanistic needs of TCM diagnosis and treatment of chronic urticaria patients from the perspective of narrative medicine.

Identifying the quality markers and optimizing the processing of Gastrodiae rhizoma to treat brain diseases

BackgroundGastrodiae rhizoma (GR) refers to the dried tuber of Gastrodia elata Bl. and has been used for many centuries to treat brain diseases, such as Alzheimer’s disease, major depressive disorder, and cerebral ischemia. However, the processing of GR is complex and varied, resulting in unstable clinical treatment effects. The processing protocols significantly affect the active ingredients and curative effects of GR. We can optimize the processing of GR by identifying quality markers to treat brain diseases.MethodsFresh tubers of G. elata Bl. were processed under eight different protocols, and their resulting contents of potentially bioactive compounds were compared using liquid chromatography mass spectrometry to screen the potential quality markers of GR through stoichiometric analysis. The potential quality markers of GR targeting Alzheimer’s disease, major depressive disorder, and cerebral ischemia were identified by network pharmacology, and the potentially neuroprotective effects of these components were validated through simulated docking to likely protein targets. Finally, a fit degree analysis was carried out using different composition ratios and proportions of the disease component degree value, and the therapeutic effects of different processing methods on Alzheimer’s disease, major depressive disorder, and cerebral ischemia were outlined clearly.ResultsWe identified 32 potential therapeutic components and screened 13 quality markers in GR, of which five quality markers (galactinol, glucosyringic acid, parishins C and E, and S-(4-hydroxybenzyl)-glutathione) showed efficacy against all three brain diseases. Furthermore, steaming and microwave-drying during processing can optimize the components of these quality markers for treating the three diseases.ConclusionProcessing protocols significantly affect the therapeutic components of GR and may also impact its effectiveness in treating brain diseases. Accordingly, optimizing the processing methods of GR to correspond to different therapeutic purposes may improve its efficacy against brain diseases.

Inhibition of Aβ Aggregation and Tau Phosphorylation with Functionalized Biomimetic Nanoparticles for Synergic Alzheimer's Disease Therapy.

The main pathological mechanisms of Alzheimer's Disease (AD) are extracellular senile plaques caused by β-amyloid (Aβ) deposition and intracellular neurofibrillary tangles derived from hyperphosphorylated Tau protein (p-Tau). However, it is difficult to obtain a good curative effect because of the poor brain bioavailability of drugs, which is attributed to the blood-brain barrier (BBB) restriction and complicated brain conditions. Herein, HM-DK was proposed for synergistic therapy of AD by using hollow mesoporous manganese dioxide (HM) as a carrier to deliver an Aβ-inhibiting peptide and a Dp-peptide inhibitor of Tau-related fibril formation synergistically. Inspired by 4T1 cancer cells promoting BBB penetration during brain metastasis, a prospective biomimetic nanocarrier (HM-DK@CM) encapsulated by 4T1 cell membranes was designed. After crossing the BBB, HM-DK@CM inhibited Aβ aggregation and prevented Tau phosphorylation simultaneously. Moreover, by taking advantage of the catalase-like activity of HM, HM-DK@CM relieved oxidative stress and altered the microenvironment associated with the development of AD. Compared with the single therapeutic drug, HM-DK@CM restored nerve damage and improved AD mice's learning and memory abilities by decreasing Aβ oligomer, p-Tau protein, and inflammation through various pathways for synergistic therapy, which has broad prospects for the effective treatment of AD.

Tanshinone I inhibits the functions of T lymphocytes and exerts therapeutic effects on delayed-type hypersensitivity reaction via blocking STATs signaling pathways

Delayed-type hypersensitivity (DTH) reactions are a kind of chronic inflammatory diseases initiated by antigens and antigen-specific T cells. Currently, the therapy of DTH reactions is limited by the poor curative effects and serious adverse reactions of existing agents. In this study, we investigated the regulatory effects of tanshinone Ⅰ, a natural compound isolated from Salvia miltiorrhiza, on the functions of multiple immune cells and its therapeutic effects on DNFB-induced DTH reaction, and then explored its immunosuppressive mechanisms. The results showed that tanshinone Ⅰ at 5 to 20 μM moderately inhibited the activation of macrophages and dendritic cells, but did not weaken the activation of neutrophils. Tanshinone Ⅰ at 1 to 4 μM intensively suppressed the activation, proliferation, and differentiation of CD4+ and CD8+ T cells, and slightly affected the functions of B cells. Tanshinone Ⅰ administration markedly alleviated the edema, inflammatory response, and the infiltrations of CD4+ T cells, CD8+ T cells, and CD11b+ cells in ear tissues of mice which were induced DTH reactions by DNFB. Transcriptome analysis revealed that tanshinone Ⅰ strongly inhibited CD4+ T cells to express genes involving in cell proliferation, metabolism, activation, and differentiation. Furthermore, immunoblotting analysis showed that tanshinone Ⅰ selectively inhibited the phosphorylation of STAT3 and STAT5 in CD4+ T cells stimulated by anti-CD3e and anti-CD28 antibodies or IL-2. Collectively, tanshinone Ⅰ can strongly inhibit the functions of T lymphocytes, exert therapeutic effects on DTH reaction by blocking STATs signaling pathways, and has potential to be developed into therapeutic drug for DTH reactions.

Identification of active ingredients in Naomaitai capsules using high-resolution mass spectrometry unite molecular network analysis and prediction of their action mechanisms.

Although Naomaitai capsule (NMC) is widely used in clinical practice and has a good curative effect for cerebral infarction, its material basis and mechanism of action remain unclear. In this study, ultra-high-performance liquid chromatography (UHPLC) coupled with quadrupole Orbitrap MS technology was used to analyse the in vivo and in vitro components of NMC, and the Global Natural Products Social Molecular Networking website was used to further analyse the components of NMC. Next, systems biology approaches were employed to investigate the mechanism of action of NMC. Finally, molecular docking technology was used to verify the network pharmacological results. In total, 177 compounds were identified in vitro, including 65 terpenoids, 62 flavonoids, 25 organic acids and 11 quinones. 64 compounds were identified in the blood of mice, and the main active components included ginkgolide C, ginkgolide A, ligustilide, tanshinone IIB, olmelin, emodin and puerarin. The main targets in vivo included TP53, SRC, STAT3, PIK3CA and PIK3R1. In conclusion, this study has revealed that NMC acts on multiple targets in the body through various active components, exerting synergistic effects in the treatment of CI. Its mechanism of action may involve inhibiting neuronal apoptosis, oxidative stress and inflammatory responses as well as reducing cerebral vascular permeability and promoting cerebral vascular regeneration.

In vivo, In vitro, and In silico Studies of Umbelliferone and Irinotecan on MDA-MB-231 Breast Cancer Cell Line and Drosophila melanogaster Larvae.

Deaths from cancer are still very common all over the world and continue to be the focus of scientific research. Chemotherapy is one of the primary treatments used to prevent deaths from cancer. Side effects of chemotherapeutic drugs and resistance of cells to drugs are essential problems that limit the treatment process. Drug combination therapy is regarded as a significant application that inhibits the growth of tumors and is anticipated to provide a solution for the issues encountered. The combination therapy aims at a synergistic effect that will limit drug resistance and cytotoxic effects with appropriate drug combinations. In this context, we aim to investigate the in vitro, in vivo, and in silico effects of single and combined doses of umbelliferone and irinotecan, known for their anticarcinogenic and curative effects, on MDA-MB-231 breast cancer cell lines and the model organism Drosophila melanogaster. Irinotecan is currently used as an anticarcinogenic drug. Anticarcinogenic effects of umbelliferone have also been detected. The in vivo, in vitro, and in silico impacts of single and combined doses use of these two agents are not yet available in the literature. This study aims to determine the anticarcinogenic effects of single and combined use of umbelliferone and irinotecan at the molecular level. It also attempts to determine the binding energies of chemicals to cancerrelated proteins through docking and molecular dynamic studies. The cytotoxic effects of individual and combinational doses of umbelliferone and irinotecan on the MDAMB- 231 cell line and D. melanogaster were calculated by XTT and probit analyses. IC50 values for the cancer cells, LC50, and LC99 values for D. melanogaster were found. Gene expression analysis was performed to determine the effects of chemical agents on miR-7, miR-11, and miR-14, and their expression levels were found. The sequences of miRNAs not found in the literature were determined, and their molecular imaging was performed. In addition, the binding energies of irinotecan and umbelliferone to Bcl-2, Bad, and Akt1 proteins, which are known to have apoptotic effects, were found by the molecular docking method. Molecular dynamics studies of Bad proteins and chemicals were also performed. The drug potential of chemicals was determined by ADME/T analysis. The cytotoxic effect on cells was calculated, and the IC50 value of umbelliferone was calculated as 158 μM, the IC50 value of irinotecan was calculated as 48,3 μM and the IC50 value was calculated as 20 μM. In the probit analysis performed to calculate the cytotoxic effects of drugs on D. melanogaster, the LC50 value of umbelliferone was 2,5 μM, and the LC99 value was 13,4 μM. The LC50 value of irinotecan was found to be 0,1 μM, and the LC99 value was 0,28 μM. It was concluded that single and combined doses of chemicals in the invasion experiment significantly affected the spread of cells. As a result of expression analysis, a significant increase in HsamiR- 7 (Homo sapiens miRNA-7), Hsa-miR-14 (Homo sapiens miRNA-14), and Hsa-miR-11(Homo sapiens miRNA-11) expression was observed in cells treated with umbelliferone irinotecan compared to the control groups. In our study, it can be concluded that the cytotoxic effects of individual and combination doses of umbelliferone and irinotecan on MDA-MB-231 cells and D. melanogaster larvae are significant. In addition, the effects of umbelliferone and irinotecan on the expression level of miR-7, which is a common D. melanogaster and human miRNA, should be widely investigated. Expression analyses and docking studies of Hsa-miR-11 and Hsa-miR-14, which have been newly studied and are not in data repositories, are important for cancer research. In particular, the expression and binding energy of these miRNAs in new drug combinations and the expression level in different cancer cell lines are important for future studies. Another crucial point is that in vivo tests using different model species validate the usage of drugs at both single and mixed dosages. Other: As a result of this study, the in vivo, in vitro, and in silico effects of single and combined doses of umbelliferone and irinotecan were determined. In future studies, it would be useful to determine the binding energies of umbelliferone and irinotecan to other cancer-related proteins and to find their interactions with different miRNAs. Additionally, studies on different model organisms are also important.

The Exploration of Protein Therapies for the Alzheimers Disease

Alzheimer’s disease (AD) is a global puzzle that first appeared in 1901, the number of patients with AD is soaring all over the world these years. While various mechanisms were proposed, such as Aβ cascade hypothesis, the results were still dissatisfactory, and they all seem to be implicated in each other. Until now, only two kinds of medicines are allowed to treat AD by the FDA, but they are not capable of achieving therapeutic effects. New attention is paid to the treatment options for lipids. This paper analyzes references about cholesterol homeostasis and transport in the brain, finding that an excellent curative effect can emerge by intraperitoneal injection of CS-6253 to raise the level of lipidation of APOE 4, which can provide the references on protein therapies and lipids mechanism for AD, promoting the proceeding of AD study. Nevertheless, the topic that make CS-6253 cross the BBB and perform effectively in the human body have not been tackled, further studies can be biased toward this aspect.

Macrophage Membrane-Coated Nanoparticles for the Delivery of Natamycin Exhibit Increased Antifungal and Anti-Inflammatory Activities in Fungal Keratitis.

This study aims to explore the efficacy and safety of macrophage membrane-coated nanoparticles for the delivery of natamycin (NAT) in the therapy of fungal keratitis (FK). Macrophage membranes were isolated and identified by immunofluorescence staining (IFS). NAT was encapsulated into poly(lactic-co-glycolic acid) (PLGA). Fungal stimulated macrophage membranes (M1) or unstimulated membranes (M) were separately mixed and sonicated with PLGA nanoparticles. The biocompatible nanoparticles (PLGA-NAT, PLGA-NAT@M, and PLGA-NAT@M1) were characterized with zeta-sizer analysis, transmission electron microscopy (TEM), and Western blot. Drug encapsulation and loading efficiency and the release of NAT in the nanoparticles were detected by ultraviolet spectrophotometry. The cytotoxicity, ocular surface toxicity and irritability, and systemic safety of nanoparticles with different concentrations were assessed. In vitro, we examined the antifungal properties of the nanoparticles. The eye surface retention time, drug release, and curative effects on FK were evaluated in vitro and in vivo. IFS results showed the separation of the macrophage membrane and nucleus. The prepared nanoparticles had a typical "core-shell" structure and uniform nanometer size, and the membrane proteins were retained on the membrane allowing to exert functional effects of macrophage. The loading efficiencies of PLGA-NAT@M and PLGA-NAT@M1 were 7.6 and 6.7%, respectively. The encapsulation efficiencies of PLGA-NAT@M and PLGA-NAT@M1 were 51.2 and 41.5%, respectively. PLGA-NAT@M and PLGA-NAT@M1 could gradually release NAT and reduce the clearance of the ocular surface. Macrophage membranes enhanced the antifungal activity of PLGA-NAT. Furthermore, the membrane coated with macrophage increased the biocompatibility and decreased the corneal toxicity of nanoparticles. In vivo, PLGA-NAT@M1 significantly alleviated the severity of FK. In vitro, PLGA@M and PLGA@M1 reduced the protein levels of inflammatory cytokines after fungal stimulation. The prepared PLGA-NAT@M1 has good physical properties and biosafety. It could evade ocular surface clearance, release NAT gradually, and achieve high antifungal and anti-inflammatory efficiencies to FK. Macrophage membrane-coated nanoparticles clinically have high application potential to the treatment of FK.

Analysis of the efficacy of vocal cord botulinum toxin injection for refractory laryngeal contact granuloma

Objective: To observe the efficacy of vocal cord botulinum toxin type A injection in the treatment of refractory laryngeal contact granuloma and to analyze the factors affecting the curative effect. Methods: Fifty-two patients with refractory laryngeal contact granuloma who received vocal cord botulinum toxin type A injection under topical anesthesia from May 2021 to May 2023 were analyzed retrospectively. Among them, 51 were males and 1 was female, aged 22-66 (48.98±8.87)years old. All patients were followed up for a minimum of 12 months. Outcome measures in terms of patient cure rate, total effective rate, complications and recurrence rate were calculated. The median [M (Q1, Q3)] was used to represent non-normally distributed measurement data, and Logistic regression analysis was used to determine independent risk factors affecting efficacy. Results: The cure rate of 52 patients with refractory laryngeal contact granuloma treated by vocal cord botulinum toxin type A injection was 78.8% (41/52), and the total effective rate (including cure, marked and effective) was 90.4% (47/52). The median number of injections was 1[1,2]. Following a single injection, the cure rate was 69.2% (36/52), and the median treatment duration for cured patients was 3 [3,3] months. Hoarseness occurred in 88.5% (46/52) of patients, with recovery within 3 months in all cases. Additionally, 21.2% (11/52) of the patients experienced cough, sore throat, dyspnea, all of whom recovered within 3 months. One patient among the 41 cured cases was lost to follow-up, and the recurrence rate at the 12th month was 17.5% (7/40). Multivariate regression analysis indicated that age, granuloma size, history of PPI treatment, previous corticosteroid injections, prior surgical excision, pharyngeal reflux, chronic cough, pharyngeal reflux, chronic cough and vocal overuse were not independent risk factors for cure and recurrence. Conclusion: Vocal cord botulinum toxin type A injection is an alternative for the treatment of refractory laryngeal contact granuloma, which offers benefits such ashigh cure rate, short treatment cycle and less injection times.
