Curative Effect Of Patients Research Articles

Network pharmacology analysis and clinical efficacy of the traditional Chinese medicine Bu-Shen-Jian-Pi. Part 1: Biogenic components and identification of targets and signaling pathways in amyotrophic lateral sclerosis patients.

There is evidence that Bu-Shen-Jian-Pi (BSJP), a traditional Chinese medicine, has curative effects in patients suffering from amyotrophic lateral sclerosis (ALS), a progressive and potentially fatal hypoxic condition. To identify biogenic components in BSJP extracts having potential pharmacological efficacy in ALS. Biogenic components in BSJP and their potential pharmacological targets and signaling pathways in ALS were identified and assessed using network pharmacology/hub node analysis. Network pharmacology analysis identified icariin, naringenin, kaempferol, quercetin, and formononetin as core components in BSJP with potential activity involving mitochondrial protection in patients with ALS. Network pharmacology analysis proved to be a successful screening tool for obtaining information from scientific databases on the pharmacology of biogenic components in BSJP showing potential therapeutic activity in ALS.

Influence of standardized nursing intervention combined with mindfulness stress reduction training on the curative effect in patients with acute pancreatitis.

Acute pancreatitis (AP) is a common inflammatory disease of the pancreas with high mortality rates. It is of great significance to take scientific intervention measures for patients with AP in time. To explore the effect of standardized nursing combined with mindfulness stress reduction training on the curative effect, negative emotion, and quality of life in patients with acute pancreatitis. A total of 80 patients with acute pancreatitis admitted to The First People's Hospital of Jiangxia District Hospital from May 2021 to May 2023 were randomly divided into control group and observation group (n = 40). Patients in control group were given the standardized nursing intervention, and the observation group were given standardized nursing plus mindfulness stress reduction training intervention. The time of clinical symptom disappeared or improved, complication occurrence rate, emotional state, and quality of life score of the two groups were observed and compared. In comparison with the control group, the bowel sound recovery time, ventosity and abdominal pain improvement time, and venting and cacation time in observation group were shorter, and the total incidence rate of complications was reduced, showing statistically significant difference (P < 0.05). The scores of anxiety and depression in observation group were lower than those in control group (P < 0.05). Serum levels of tumour necrosis factor alpha, interleukin (IL)-6, IL-1β and IL-8 in observation group were lower than those in control group (P < 0.05). The scores of life quality in physiology, psychology, environment and social relations in observation group were higher than those in control group, and the differences were statistically significant (P < 0.05). The application of standardized nursing intervention combined with mindfulness stress reduction training in patients with acute pancreatitis has a definite effect, which can help to ameliorate the clinical symptoms, anxiety and depression of patients, reduce the incidence rate of complications, and improve the prognosis of patients.

Gel-ultraphonophoresis for patients with scarring on the skin: results of comparative prospective intervention study

INTRODUCTION. In modern realities of peace and military trauma there are an increasing number of scar skin defects, often accompanied by pronounced subjective sensations and tissue functional limitations. An urgent task is the scientific substantiation of effective methods of their correction.&#x0D; OBJECTIVE. To determine healing effects and safety of using ultraphonophoresis of enzyme gel with high transcutaneous and proteolytic activity in patients with scarring on the skin.&#x0D; MATERIALS AND METHODS. There was examination of 82 patients with emerging (N=21 study group, N=16 comparison group) and mature (N=25 study group, N=20 comparison group) scar skin of different localizations at the rehabilitation stage after various injuries, burns, removal of skin neoplasms. The study applied clinical and functional methods in the assessment of scar tissue, medical and sociological methods in evaluating patients’ quality of life and safety profile.&#x0D; RESULTS. There were improved clinical indicators and functional skin properties in the scar area, a significant regression of subjective sensations, an increased quality of life score, more pronounced in the study groups. Dynamics of clinical indicators is more expressed in group 1 and group 3. Vascularization values before and after treatment in the groups were: in group 1 and 3 before treatment - 6,4±0,93 and 5,8±0,25, after - 3,0±0,24 and 2,7±0,31, respectively; in group 2 the values before and after treatment were 5,6±0,26 и 4,2±0,62, respectively, in group 4 – before treatment 4,9±0,53, after - 4,1±0,48. As a result of dynamics of the quality of life indicators, a more significant improvement was found in the study groups with respect to the comparison groups. In the group with emerging scars the sum of points before treatment was 20,4±0,3, after treatment - 12,4±0,3; in the comparison group - 18,7±0,5 and 13,4±0,5 before and after treatment, respectively; in the group with mature scars: before treatment - 23,6±0,3, after - 13,7±0,4; in the comparison group - 21,3±0,4 и 16,2±0,5 before and after treatment, respectively. A favorable safety profile of treatment was defined: adverse events (tingling, burning) were transient and fully cupped after the procedure.&#x0D; DISCUSSION. Ultraphonophoresis, one of the man methods in the transdermal delivery, contributes to changing the epidermal barrier permeability for molecules of various drugs as well as potentiation for actions of anti-scarring agents at different stages of emerging and existing scar skin defects.&#x0D; CONCLUSION. Ultraphonophoresis of the enzyme gel with a high transcutaneous and proteolytic activity has fibromodulating and sedative curative effects in patients with scarring skin of different genesis and duration.

D-D and PLR, NLR combined forecasting first-line treatment: The short-term curative effect and prognosis of patients with SCLC.

The aim of this study was to evaluate the difference in D-dimer (D-D) combined with the platelet lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) before treatment in small cell lung cancer (SCLC) patients receiving first-line treatment and to analyze the efficacy and prognosis. We retrospectively collected the records of SCLC patients treated in our hospital from February 2019 to January 2023 and finally included 100 patients. A binary logistic regression analysis method was applied to analyze the relationship between D-D, PLR, and NLR and short-term efficacy. Univariate and multivariate Cox regression analyses were utilized to estimate the individual effect of plasma parameters on progression-free survival (PFS). The optimal cutoff values of D-D, PLR, and NLR for predicting survival outcome were determined by receiver operating characteristic curve analysis. Kaplan-Meier survival analysis was utilized to examine the correlation between D-D, PLR, and NLR the prognosis of SCLC patients. PLR was associated with a short-term curative effect in patients with SCLC (odds ratio: 0.326, 95% confidence interval [CI]: 0.135 0.790). Univariate Cox regression showed that D-D (hazard ratio [HR]: 0.495, 95% CI: 0.323-0.758), PLR (HR:0.420, 95% CI: 0.269-0.655) and NLR (HR: 0.407, 95% CI: 0.263-0.630) were associated with PFS in SCLC patients (P < .05). Multivariate Cox regression analysis showed that PLR (HR: 2.395, 95% CI: 1.468-3.906) and NLR (HR: 2.148, 95% CI: 1.319-3.499) correlated significantly with PFS (P < .05). The optimal cutoff values of D-D, PLR and NLR for predicting PFS were 0.88 mg/L (65.4% and 68.7%), 195.44 (61.5% and 81.2%) and 3.63 (63.5% and 81.2%), respectively, and the corresponding area under receiver (AUC) operating characteristic curve 0.691 (95% CI: 0.587-0.795), 0.721 (95% CI: 0.620-0.822) and 0.714 (95% CI: 0.614-0.815). When D-D was used in combination with PLR or NLR, the corresponding AUCs were 0.737 (95% CI: 0.640-0.835) and 0.761 (95% CI: 0.667-0.855). Pretreatment PLR is an independent predictor of short-term efficacy in SCLC patients. Pretreatment D-D, PLR and NLR are potential biochemical markers for predicting the prognosis of SCLC patients treated with first-line treatment. When D-D is combined with PLR and NLR, it shows stronger predictive ability.

Objective: To evaluate the efficacy of emergency ventilator therapy in severe acute left heart failure. Methods: A total of 75 patients with severe acute left ventricular heart failure who were admitted to the hospital from July 2020 to July 2023 were randomly divided into two groups. Group A received additional emergency ventilator treatment, and group B received conventional treatment. The efficacy was compared. Results: The curative effect of patients with severe acute left heart failure in group A was higher than that in group B (P &lt; 0.05); all blood gas indicators in group A were better than those in group B (P &lt; 0.05); all vital signs indicators in group A were better than those in group B (P &lt; 0.05); group A was more satisfied with the treatment of severe acute left ventricular heart failure than group B (P &lt; 0.05). Conclusion: Patients with severe acute left heart failure who receive emergency ventilator treatment can stabilize vital signs, improve blood oxygen supply, and enhance curative effect.

Clinical-grade natural killer cells expanded from donor peripheral blood and anti-leukemia effect against myeloid leukemia.

e19018 Background: Natural killer (NK) cells play a crucial role in immune surveillance and tumor clearance. It has been reported that allogeneic NK cell therapy has good safety and curative effect in patients with refractory and relapsed acute myeloid leukemia (AML). However, the clinical application of adoptive NK infusion is limited due to the lower number of human NK cells. We established a feeder-free NK cell expansion system from peripheral blood (PB) and explore the anti-leukemia potential in preclinical and clinical studies. Methods: The killing capacity of ex vivo-expanded NK cells were detected by Flow cytometry. The in vivo expansion, survival and anti-leukemia activity of the expanded NK cells were detected in K562-bearing NSG mice. Six AML patients with hematological/extra medullary relapsed (n = 3) or persistent positive minimal residual disease (n = 3) after consolidation and maintenance therapy were enrolled in Peking University Institute of Hematology from 2021 to 2022. The patients were treated with high-dose cyclophosphamide and fludarabine, then combined with adoptive infusion of donor-derived expanded NK cells. The chimerism, the number and function of NK cells were analyzed, and the safety and clinical efficacy were evaluated. Results: The ex vivo-expanded NK cells exhibit highly anti-leukemia activity. NK cells proliferate in mice and the CD56+ cells to reach the peak time in each organ is 3-7 days and drop to the level before infusion after 14 days. NK cell infusion significantly improve the survival of leukemia mice, and the anti-leukemia effect is NK cell dose-dependent. In the clinical trial, six patients received a total of 7 cases of NK cell infusion, including 3 cases in low-dose group and 4 cases in middle-dose group, among which 1 patient received 2 dose (1 low-dose and 1 middle-dose). In the low-dose group, 1 patient got response (1/3), with the minimal residual disease turned negative. In the middle-dose group, 3 patients responded (3/4), of which 1 patient had the fusion gene CBFB /ABL decreased from 0.99% to 0.13%, 1 case of extramedullary recurrence of AML turned negative, and NK cells could be detected in cerebrospinal fluid, 1 case of hematological recurrence got hematological remission after treatment. The survival time of NK cells in vivo was 7d-30d, with longer time in middle dose group than those in low dose group. The proportion and number of NK cells in responding cases were significantly higher than those in non-responsive group. Conclusions: Clinical grade expanded NK cells has strong anti-leukemia activity in patients with relapse or minimal residual positive AML patients. NK cells can survive for 2 weeks and can enter the central nervous system without obvious adverse reactions. The response rate in middle-dose group is higher than that in low-dose group. However, the efficacy of NK cells still needs to be further confirmed in a large sample size. Clinical trial information: NCT04221971 .

Abstract 893: Memory like differentiation enhances in vitro and in vivo NK cell responses against colorectal cancer

Abstract Metastatic (m) colorectal cancer (CRC) is an incurable, frequently lethal disease present in approximately 25% of newly diagnosed CRC patients, and almost 50% of the patients with CRC will develop metastatic disease. For mCRC, while systemic therapies (cytotoxic therapy, targeted therapy, immunotherapy or their combinations) have extended patient’s life expectancy, not all patients are candidates for these treatments. Immunotherapy has achieved significant curative effects in patients with solid tumors; however, a considerable proportion of mCRC patients (~90%) are not responsive to immune checkpoint blockade (ICB) leaving a gap in the CRC immunotherapy options. Natural killer (NK) cells are cytotoxic innate lymphoid cells that display potent effector responses against a wide variety of tumor cells; however, they are frequently dysfunctional in cancer patients. NK cells from CRC patients exhibit decreased expression of activating receptors and reduced cytokine production after stimulation with CRC cells with a more accentuated phenotype in advanced stages of the disease. Memory-like (ML) NK cells differentiated after IL-12, IL-15, and IL-18 activation have been shown to overcome limitations associated with deficient tumor recognition and poor anti-tumor activity. In clinical trials, ML NK cells were safe and active against acute myeloid leukemia (Romee R et al, Sci Transl Med, 2016). Preclinically, ML NK cells exhibited improved responses against melanoma (Marin ND et al, Clin Cancer Res, 2021) and ovarian cancers, compared to conventional NK cells. Here, we hypothesized that memory-like differentiation will enhance multiple aspects of the NK cell response against CRC cells. Allogeneic ML NK cells displayed enhanced IFN-γ production against four CRC cell lines DLD-1 (p=0.015), SW480 (p=0.0005), HT-29 (p=0.0005) and HCT116 (p=0.001), as well as primary patient derived CRC tumoroids (p=0.0156), compared to conventional (c) NK cells. ML NK cells also exhibited superior and sustained killing of CRC cell lines over time compared to cNK cells, as measured by Incucyte assays and using CRC tumoroids. Furthermore, IFN-γ production was significantly reduced after blockade of NKG2D, DNAM-1 and NKp46 (p&amp;lt;0.01) revealing mechanistic insights into how ML NK cells recognize CRC targets. Finally, using a xenograft model of CRC in NSG mice, we demonstrated that ML NK cells exhibited superior control of Luciferase expressing HCT116 cells compared to cNK cells (p=0.01) as measured by bioluminescent imaging (BLI). Collectively, these findings demonstrate that ML NK cells exhibit enhanced responses against CRC cells, and thus warrants further investigation in clinical trials for CRC patients, especially those who are not candidates for standard of care therapy or failed ICB.

Effect of various types of photodynamic therapy on inflammatory and non-inflammatory lesions in patients with acne: A network meta-analysis of randomized controlled trials

BackgroundRecent studies have demonstrated that photodynamic therapy (PDT) is safe and effective in treating acne vulgaris. The present study aimed to evaluate various PDTs on inflammatory and non-inflammatory lesions in patients with acne by a network meta-analysis (NMA) of randomized controlled trials (RCTs). MethodsThe researchers of this paper searched PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception to March 2022 to identify suitable RCTs. The included studies were evaluated for methodological quality using the Cochrane bias risk assessment tool. Twenty-one RCTs were included, with a total sample size of 898 participants. ResultsNetwork meta-analysis (NMA) revealed that indocyanine green (ICG) + near-infrared (NIR) diode laser, ICG+830 nm light-emitting diode (LED), indole-3-acetic acid (IAA) + 520 nm LED, and 5-aminolevulinic acid (ALA) + sunlight demonstrated obvious curative effects in patients with acne vulgaris. Importantly, ICG+NIR diode laser provided the greatest improvement in both inflammatory and non-inflammatory acne lesions (surface under the cumulative ranking curve [SUCRA]: 84.4% and 93.5%, respectively). ConclusionsBased on the NWM and SUCRA ranking, ICG + NIR diode laser can be considered more effective in treating acne than the other PDTs of the RCTs. However, this conclusion should be interpreted with caution due to the limitations of the present study.

Angiogenesis-related gene signatures reveal the prognosis of cervical cancer based on single cell sequencing and co-expression network analysis.

Cervical cancer ranks first in female reproductive tract tumors in terms of morbidity and mortality. Yet the curative effect of patients with persistent, recurrent or metastatic cervical cancer remains unsatisfactory. Although antitumor angiogenic drugs have been recommended as the first-line treatment options for cervical cancer, there are no comprehensive prognostic indicators for cervical cancer based on angiogenic signature genes. In this study, we aimed to develop a model to assess the prognosis of cervical cancer based on angiogenesis-related (AG) signature genes, and to provide some reference for the comprehensive treatment of cervical cancer in the clinical setting. First we screened the AG gene set from GeneCard website, and then performed angiogenesis-related scores (AGS) per cell from single cell sequencing dataset GSE168652, followed by performing weighted gene co-expression network analysis (WGCNA) for cervical cancer patients according to angiogenesis phenotype. Thus, we established a prognostic model based on AGS by taking the intersection of WGCNA angiogenic module gene and differential gene (DEGs) of GSE168652. The GSE44001 was selected as an external validation set, followed by performing ROC curve analysis to assess its accuracy. The results showed that we successfully constructed a prognostic model related to the AG genes. Patients in the high-AGS group in both the train, test and the validation sets had a worse prognosis than those in the low-AGS group, had lower expression of most immune checkpoint-associated genes and lower tumor mutational burden as well. Patients in the low-AGS group were more sensitive to AMG.706, Bosutinib, and Lenalidomide while Imatinib, Pazopanib, and Sorafenib were more recommended to patients in the high-AGS group. Finally, TXNDC12 and ZC3H13, which have high hazard ratio and poor prognosis in the model, were highly expressed in cervical cancer cell lines and tissue. Meanwhile, the results showed that TXNDC12 promoted the migration of cervical cancer cells and the tubule-forming ability of endothelial cells. In conclusion, our model based on genes with AG features can effectively assess the prognosis of cervical cancer, and can also provide reference for clinicians to choose immune-related treatments.

Effect of Mirena Intrauterine Device on Endometrial Thickness, Quality of Life Score, and Curative Effect in Patients with Perimenopausal Abnormal Uterine Bleeding.

Objective To study the effect of Mirena intrauterine device (IUD) on endometrial thickness, life quality score, and curative effect in patients with perimenopausal abnormal uterine bleeding. Methods Eighty patients with perimenopausal abnormal uterine bleeding cured from January 2020 to December 2021 were enrolled as the object of study. According to random number table, the patients were classified into the study (n = 40) and control (n = 40) groups. The control cases were cured with medroxyprogesterone. The study cases were cured with Mirena IUD. The effective rate of clinical therapies was evaluated after 3 months of treatment. The endometrial thickness, menstrual volume score, and life quality score (WHOQOL-BREF) was measured after 1 month, 2 months, and 3 months of treatment. Results The effective rate of patients with Mirena IUD for 3 months was higher compared to the control group (P < 0.05). The endometrial thickness and menstrual volume scores of study cohort after 1 month, 2 months, and 3 months following treatment were remarkably lower than those before treatment (P < 0.05) and were considerably lower than those of control cohort (P < 0.05). The hemoglobin level of the studied cases after 1 month, 2 months, and 3 months after therapy was remarkably upregulated (P < 0.05) and was greatly higher compared to the controlled cases (P < 0.05). After 3-month treatment, the WHOQOL-BREF score of the study group was higher compared to the control group (P < 0.05). Conclusion The Mirena IUD is far more effective in the treatment of perimenopausal abnormal uterine bleeding and is helpful in reducing the thickness of the endometrium. Patients' menstrual flow can be controlled, and anemia can be corrected; thus, patients improve their quality of life and health status and can be considered for further promotion.

Effect of Gualou Honghua Gancao Decoction on Serum Inflammatory Factors and Curative Effect in Patients with Herpes Zoster

Analysis of clinical features and treatment of pyoderma gangrenosum

Objective: To explore the clinical features and treatment of pyoderma gangrenosum (PG). Methods: A retrospective observational study was conducted. From January 2012 to July 2021, 25 patients with PG who met the inclusion criteria were admitted to Beijing Fucheng Hospital, including 16 males and 9 females, with the age of onset of disease being 14 to 75 years. Among them, the classification of PG identified 17 cases of ulcerative type, 6 cases of pustular type, 1 case of proliferative type, and 1 case of bullous type. Six patients were accompanied with systemic diseases, while 19 patients were not accompanied with systemic diseases. At the same time of systemic treatment with glucocorticoids, dressing changes or surgical skin grafting was performed on the wounds. The results of laboratory and histopathological examinations, the overall curative effects and follow-up of patients, the wound healing time of patients with negative and positive microbial culture results of wound secretion specimens, and the curative effects of patients with and without systemic diseases were analyzed. Results: The results of blood routine examination of 19 patients were abnormal, and all the immunological indexes were normal in all the patients; the microbial culture results of wound secretion specimens were positive in 14 patients; and the histopathological examination results of ulcer boundary tissue in 15 patients with rapid wound progress were mainly local tissue inflammatory changes. The wounds were cured in 17 patients, mostly healed in 7 patients, and not healed in 1 patient. After one-year's follow-up, the PG in 3 patients relapsed due to self-discontinuation of medication after discharge, and the wounds were healed gradually after adjustment of medication, while the remaining patients had no relapse. The days of wound healing in 14 patients with positive microbial culture results of wound secretion specimens were 21-55 days, and the days of wound healing in 11 patients with negative microbial culture results in wound secretion specimens were 20-54 days. In the 6 patients with systemic diseases, the wounds of 3 patients were cured, and the wounds of the other 3 patients were mostly healed. In the 19 patients without systemic diseases, the wounds of 14 patients were cured, the wounds of 4 patients were mostly healed, and the wound of 1 patient was not healed. Conclusions: The laboratory examination and pathological manifestations of patients with PG lacks characteristics, and their clinical manifestations are rich and diverse, thus PG can be easily misdiagnosed. The glucocorticoids combined with immunosuppressive therapy have good effects on PG. Surgical intervention can be performed on the wounds. Specifically, excessive debridement is not recommended in the acute phase, but skin grafting can be performed in the contraction phase.

Vomiting Management and Effect Prediction after Early Chemotherapy of Lung Cancer with Diffusion-Weighted Imaging under Artificial Intelligence Algorithm and Comfort Care Intervention.

This aim of this research was to explore the evaluation and prediction value of diffusion-weighted imaging (DWI) under artificial intelligence algorithm in the vomiting management and chemotherapy of early lung cancer under comfort care. 118 patients with lung cancer were included as the research objects. They were randomly divided into the control group (routine care) and the experiment group (comfort care) with 59 cases in each. The DWI under the weighted nuclear norm minimization (WNNM) noise reduction algorithm was used for examinations. The noise reduction effect of the algorithm under different Gaussian noises, as well as the sensitivity, specificity, and area under the curve (AUC) of the apparent diffusion coefficient (ADC) maps under different b values, was compared and analyzed. The indicators of vomiting, psychological state, quality of life, serum tumor marker levels, and nursing satisfaction were also compared between the two groups of patients after chemotherapy. Compared to the photon mapping (PM) algorithm and the total variation (TV) norm minimization algorithm, the WNNM algorithm had the most ideal noise reduction effect with clearer images, which was conducive to identification. When the b value was 800 s/mm2, the ADC chart had the best sensitivity, specificity, and AUC values of 0.95, 0.89, and 0.87, respectively. After chemotherapy, 45.76% of patients in the experiment group had vomiting in degree 0 and 40.68% had that in degree I, which suggested that the incidence of vomiting was significantly lower than that in the control group (P < 0.05). All of the psychological state, quality of life, serum tumor marker levels, and nursing satisfaction of patients in the experiment group were significantly better than those in the control group (P < 0.05). It showed that comfort care could alleviate the vomiting response effectively of patients with lung cancer after chemotherapy and had significant effects in improving the quality of life, the psychological state, and curative effect of patients. WNNM algorithm had the better noise reduction effect in DWI image processing. This work provided a certain reference for the nursing intervention plan after chemotherapy of early lung cancer.

MFG-E8 promotes tendon-bone healing by regualting macrophage efferocytosis and M2 polarization after anterior cruciate ligament reconstruction.

BackgroundScar tissue formation at the tendon-bone interface caused by excessive inflammation leads to insufficient healing strength, while the phagocytic clearance of dying cells (efferocytosis) has profound consequences on macrophage polarisation and the inflammatory response. Modulating the inflammatory microenvironment may have satisfactory curative effects in patients with anterior cruciate ligament reconstruction (ACLR).MethodsBone marrow-derived macrophages (BMDMs) and polymorphonuclear leukocytes (PMNs) were harvested from bone marrow. The effects of milk fat globulin protein E8 (MFG-E8) on macrophage polarisation were compared with those of M1 and M2 macrophages induced by conventional methods. The BMDMs and apoptotic PMNs co-culture system was used to assess the efficiency of efferocytosis. The biological functions of MFG-E8 in tendon-bone healing by regulating macrophage efferocytosis and polarisation were further investigated using a rat ACLR model.ResultsBMDMs and PMNs were successfully isolated. Compared to conventional induction methods, MFG-E8 alone did not significantly induce macrophage M1 or M2 polarisation, but it could partially reverse the expression of inducible nitric oxide synthase (iNOS) in M1 macrophages. In vitro studies revealed that appropriate dosing of MFG-E8 could significantly promote the efficiency of macrophage efferocytosis and subsequently increase M2 polarisation. More importantly, significantly increased peri-tunnel new bone formation, tighter connected interface and better mechanical properties were observed after ACLR when treated with MFG-E8 in vivo. We further demonstrated that MFG-E8 remarkably facilitated the clearance of apoptotic cells and increased the number of M2 macrophages at the interface between the tendon graft and bone tunnel in the early postoperative stage.ConclusionMFG-E8 promoted tendon-bone healing histologically and biomechanically, probably by the regulation of inflammatory processes via macrophage efferocytosis and M2 polarisation.The translational potential of this article: Regulation of macrophage efferocytosis and M2 polarization by MFG-E8 is expected to be a therapeutic strategy for promoting tendon-bone healing in patients undergoing ACLR.

Effect of Pulmonary Rehabilitation on Postoperative Clinical Status in Patients with Lung Cancer and Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

Pulmonary rehabilitation (PR) has a curative effect in patients undergoing pneumonectomy for lung cancer. Nevertheless, the contribution of PR to the clinical status of patients with chronic obstructive pulmonary disease (COPD) undergoing lung resection has not been adequately elucidated. The aim of this systematic review of randomized and nonrandomized controlled trials was to appraise the impact of PR compared to conventional treatment based on postoperative clinical status in patients with lung cancer and COPD. Literature in English from PubMed, Cochrane Library, Science Citation Index, and Embase databases and in Chinese from the Chinese National Knowledge Infrastructure and the WANFANG Database was retrieved from inception to November 2021, employing the keywords “Pulmonary Neoplasms,” “Chronic Obstructive Pulmonary Diseases,” “Physical Therapy Modalities,” and “pulmonary rehabilitation.” Only studies that reported PR results were included. This review was registered in the International Prospective Register of Systematic Reviews (number: CRD42021224343). A total of nine controlled trials with 651 patients were included. Postoperative pulmonary complications (PPCs) were the primary outcome measure. PR decreased the risk of complications after surgery compared to regular treatment (odds ratio (OR) 0.21, 95% confidence interval (CI) 0.12–0.37, P < 0.01). PR reduced the risk of pneumonia after surgery compared to regular treatment (OR 0.36, 95% CI 0.15–0.86, P=0.02). There was a significant difference in the postoperative length of stay (mean difference −2.13 days, 95% CI −2.65 to −1.61 days, P < 0.05). PR was an effective intervention that decreased PPCs in patients suffering from lung cancer and COPD. However, due to the limitations of the available data, the results should be interpreted with caution.

Clinical observation on plastic splint treatment of middle clavicle fracture based on a new classification

According to 73 patients with middle clavicle fracture treated conservatively, a new classification of middle clavicle fracture was proposed, and the clinical effect of plastic splint in the treatment of middle clavicle fracture was observed. Total 73 patients with middle clavicle fracture treated with plastic splint from September 2018 to August 2020 were analyzed retrospectively. All the patients were divided into 4 types according to the degree of fracture displacement. There were 16 cases of typeⅠ, including 7 males and 9 females, ranging in age from 18 to 37 years old, with a mean of (28.6±7.8) years old;12 cases of mild disease, 3 cases of moderate disease and 1 case of severe disease. There were 16 cases of type Ⅱ, including 6 males and 10 females, ranging in age from 25 to 49 years old, with a mean of (37.3±9.4) years old;5 cases of mild disease, 8 cases of moderate disease and 3 cases of severe disease. There were 7 cases of type Ⅲ, including 4 males and 3 females, ranging in age from 33 to 57 years old;2 cases of mild disease, 3 cases of moderate disease and 2 cases of severe disease. There were 34 cases of type Ⅳ, including 16 males and 18 females, ranging in age from 48 to 82 years old, with a mean of(66.4±14.9) years old;7 cases of mild disease, 17 cases of moderate disease and 10 cases of severe disease. All patients received plastic splint external fixation for 4 weeks. Visual analgue scale (VAS) and Constant-Murley shoulder scores before treatment and 1, 3 and 9 months after treatment were observed and recorded to evaluate the change of pain degree and shoulder function recovery before and after treatment. The patients' satisfaction with the appearance after treatment was recorded at the latest follow-up. The X-ray findings at the latest follow-up were used to judge whether the patient had fracture nonunion. And according to the fracture healing time and imaging findings, the excellent and good rate of clinical curative effect in patients with different types was obtained. All patients were followed up, and the duration ranged from 9 to 11 months, with a mean of (9.8±0.7) months. The VAS scores of typeⅠ, typeⅡand type Ⅳ before treatment were 2.88±0.83, 3.67±0.80 and 6.92±1.71 respectively, which were decreased to 0.54±0.19, 0.77±0.25 and 1.18±0.17 respectively after 9 months of treatment. The Constant-Murley shoulder scores of typeⅠ, typeⅡand type Ⅳ were 65.81±2.09, 63.50±2.22 and 47.93±2.91 respectively before treatment, and increased to 88.56±2.11, 85.12±2.23 and 71.25±2.16 respectively after 9 months of treatment. Five patients were not satisfied with the appearance after treatment;6 patients had no obvious continuous callus passing through after 9 months of treatment, which was fracture nonunion. The classification of middle clavicle fracture is more appropriate to the clinic, which has a certain clinical guiding significance for the selection of treatment methods and prognosis of middle clavicle fracture. Plastic splint is effective in the treatment of middle clavicle fracture without obvious displacement and overlapping displacement, and the incidence of complications is low. It can be popularized in clinic.

Meta‐Analysis of Effects of Nutritional Intervention Combined with Calcium Carbonate D3 Tablets on Bone Mineral Density, Bone Metabolism, and Curative Effect in Patients with Osteoporosis

To investigate the changes in bone mineral density, bone metabolism, and efficacy of nutritional intervention combined with calcium carbonate D3 tablets in patients with osteoporosis, a RevMan 5.2 software meta-analysis was conducted in this study. According to the therapeutic direction of nutritional intervention combined with calcium carbonate D3 tablets for osteoporosis patients, relevant literature were searched in Wanfang Medical, CNKI, VIP, and PubMed literature databases at home and abroad. Keywords included bone mineral density, bone metabolism, blood calcium (Ca), blood phosphorus (P), osteocalcin (OC), bone mineral density (BMD), serum alkaline phosphatase (ALP), efficacy, osteoporosis, and nutritional intervention. Literature that met the criteria were deleted, and meta-analysis was performed using RevMan 5.2 software. The results indicate that a total of 10 Chinese literature were included. Compared with the monotherapy group, the clinical efficacy, osteocalcin, BMD, alkaline phosphatase, calcium, and phosphorus were significantly higher in the combination group (P < 0.05). Based on calcium carbonate D3, treatment combined with nutritional intervention can enhance the clinical efficacy, bone metabolism, and bone mineral density of patients with osteoporosis, and nutritional intervention combined with calcium carbonate D3 tablets is a feasible program to promote the recovery of patients with osteoporosis.

Effects of high-dose recombinant human growth hormone treatment on IGF-1 and IGFBP-3 levels in idiopathic dwarfism patients.

Objective:To investigate the effects of high-dose recombinant human growth hormone(rhGH) treatment on insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) levels in patients with idiopathic dwarfism.Methods:This study retrospectively investigated records of idiopathic dwarfism patients treated at Anhui Children’s Hospital or the Affiliated Hospital of Xuzhou Medical University between May 2019 and October 2020. The study identified 76 patients, which were divided based on rhGH treatment dosage into high- and low-dose groups.Results:The high-dose group showed a total efficacy of 95.3%, which was significantly higher than the 79.41% observed in the low-dose group (P<0.05). Moreover, height, weight, IGF-1 levels, and IGFBP-3 levels were all significantly elevated in the high-dose group compared to the low-dose group (P<0.05). No significant difference in adverse reaction incidence was observed between high- (9.5%) and low-dose (8.8%) groups (P>0.05).Conclusions:Higher doses of rhGH can provide improved curative effects in patients with idiopathic short stature, likely via elevated levels of IGF-1 and IGFBP-3.

Deciphering the Synergistic Mechanism of Cortistatin towards Cancer Targets Using Network Pharmacology Approach

Abstract: Steroidal alkaloid cortistatin is a promising marine natural compound isolated from marine sponges Corticium simplex. Experimental studies and clinical evidence have shown that cortistatin and its derivatives have a curative effect in patients with autoimmune disorders, HIV infection and several types of cancer. The objective of our study was to examine the potential cancer-related therapeutic objectives of Cortistatin using a network pharmacology method, which is a computational approach, including inverse pharmacophore research, enrichment analysis, molecular docking and dynamics study. Systematic protocol also involves the assessment of ADMET parameters to define the pharmacokinetic profile of cortistatin. Inverse pharmacophore search method was used for computational target fishing and target proteins were ranked based on the graph theory approach. Cancer target proteins, namely HSP90, EGFR, CDK2, MMP13, MAPK13, AR, ESR1, PTPN11 and SRC, were classified as top-ranking proteins according to graph theory parameters, namely MCC, DMNC, MNC, Degree(Local-based methods), EPC, Bottleneck, Eccentricity, Closeness, Radiality, Betweenness, Stress(Global-based methods) and Clustering Coefficient. Enrichment assessment established on Gene Ontology and pathway analysis of these proteins that play a vital role in cancer pathways, FaxO Signalling pathways, Ras Signalling pathways and tyrosine metabolism. Molecular docking and dynamic simulation studies of cortistatin with proposed target proteins were found to be stable and conformers generated after 3ns were consistent with stable inter-molecular interactions. The current study summarized here would provide a broad perspective on the therapeutic potential of cortistatin and provide new insights into the future development of cancer therapy strategies.
