ABSTRACT

Cough variant asthma (CVA) is a chronic respiratory disease with cough as its main symptom. The occurrence of CVA is closely related to non-specific airway inflammation, and its pathogenesis involves environmental, genetic, immune, and other factors. In recent years, the advantages of traditional Chinese medicine (TCM) in the treatment of CVA have attracted the attention of experts and scholars in China and abroad, especially its prominent role in regulating immune balance, relieving cough symptoms in CVA patients, and reducing recurrence. T Helper cells 1 (Th1), T helper cells 2 (Th2), T helper cells 17 (Th17), and regulatory T cells (Treg) are derived from CD4+ T cells. Immune imbalance of Th1/Th2 and Th17/Treg is a new hotspot in the pathogenesis of CVA and a potential key target in the treatment of CVA by TCM. Th cell subsets are in dynamic balance under physiological conditions, maintaining respiratory immune homeostasis in which pro-inflammatory cytokines and anti-inflammatory cytokines are balanced. Immature helper T cells (Th0) can be differentiated into Th1, Th2, Th17, Treg, and other cell subsets due to cytokine types in the microenvironment in the stage of CVA maturation. The proliferation of Th2 cells leads to eosinophilic airway inflammation. Excessive differentiation of Th17 cells induces neutrophil airway inflammation. Th1/Th2 and Th17/Treg cells are mutually restricted in number and function, and the immune imbalance of Th1/Th2 and Th17/Treg is easy to aggravate the generation of inflammatory response. Restoring immune balance is particularly important for the airway anti-inflammatory therapy of CVA. In this paper, the imbalance of Th1/Th2 and Th17/Treg and the pathogenesis of CVA were systematically expounded. Meanwhile, the latest research on the regulation of immune imbalance by TCM compound, single TCM, and its effective ingredients in the treatment of CVA was reviewed. It provides ideas and references for revealing the scientific connotation of TCM regulating immune balance therapy of CVA, as well as the development of clinical treatment and basic research of CVA.

ABSTRACT

With the rapid development of modern biomedicine, subjective factors such as human emotion and disease experience are diluted. Accurate data, programmed diagnosis and treatment process and other objective factors cut off the effective communication between doctors and patients, aggravating the already tense doctor-patient relationship and intensifying various conflicts in the clinic. In order to improve clinical humanistic care, medical and nursing workers have launched reflections and explorations. Narrative medicine is a new form of medical humanistic practice, while parallel chart, as an important way of its practice, records patients’ subjective experiences and painful feelings. It is of great theoretical significance and clinical value to sinicize narrative medicine and construct and promote parallel chart in Traditional Chinese Medicine (TCM) by studying the research progress of parallel chart in China and its application in TCM.

ABSTRACT

The study was carried out to understand the changes in the ethical cognition status of laboratory animals and the effectiveness of laboratory animal ethics education among medical students in Xiangya School of Medicine of Central South University (CSU), and provide new enlightenment for further strengthening the ethical education of laboratory animals. In the study, the same self-compiled questionnaire was used to investigate the ethical cognition of experimental animals among medical students in Xiangya School of Medicine of CSU in 2011 and 2021, and 359 and 363 questionnaires were collected respectively. Through comparative analysis of the questionnaire results before and after ten years, it was found that medical students’ animal experiment operation and attitudes towards laboratory animals, cognition of experimental animal ethics knowledge and their attitude to animal experiment ethics education were significantly improved. It showed that the state of experimental animal ethics cognition among medical students in Xiangya School of Medicine of CSU had improved significantly in recent 10 years, but the cognition of experimental animal ethics knowledge was higher than the actual behavior of caring for experimental animals, and there was the phenomenon of "separation of knowledge and action". The ethics education of experimental animals needs to pay more attention to the development of students’ behavior of caring for experimental animals.

ABSTRACT

OBJECTIVE@#To evaluate the associations of lipid indicators and mortality in Beijing Elderly Comprehensive Health Cohort Study.@*METHODS@#A prospective cohort was conducted based on Beijing Elderly Comprehensive Health Cohort Study with 4499 community older adults. After the baseline survey, the last follow-up was March 31, 2021 with an average 8.13 years of follow-up. Cox proportional hazard model was used to estimate the hazard ratios (HR) with 95% CI for cardiovascular disease (CVD) death and all-cause death in associations with baseline lipid indicators.@*RESULTS@#A total of 4499 participants were recruited, and the mean levels of uric acid, body mass index, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol (TC), triglyceride, and low-density lipoprotein cholesterol (LDL-C) showed an upward trend with the increasing remnant cholesterol (RC) quarters (Ptrend < 0.05), while the downward trend was found in high-density lipoprotein cholesterol (HDL-C). During the total 36,596 person-years follow-up, the CVD mortality and all-cause mortality during an average 8.13 years of follow-up was 3.87% (95% CI: 3.30%-4.43%) and 14.83% (95% CI: 13.79%-15.86%) with 174 CVD death participants and 667 all-cause death participants. After adjusting for confounders, the higher level of TC (HR = 0.854, 95% CI: 0.730-0.997), LDL-C (HR = 0.817, 95% CI: 0.680-0.982) and HDL-C (HR = 0.443, 95% CI: 0.271-0.724) were associated with lower risk of CVD death, and the higher level of HDL-C (HR = 0.637, 95% CI: 0.501-0.810) were associated with lower risk of all-cause death. The higher level of RC (HR = 1.276, 95% CI: 1.010-1.613) increase the risk of CVD death. Compared with the normal lipid group, TC ≥ 6.20 mmol/L group and LDL-C ≥ 4.10 mmol/L group were no longer associated with lower risk of CVD death, while RC ≥ 0.80 mmol/L group was still associated with higher risk of CVD death. In normal lipid group, the higher levels of TC, LDL-C and HDL-C were related with lower CVD death.@*CONCLUSIONS@#In community older adults, higher levels of TC and HDL-C were associated with lower CVD mortality in normal lipid reference range. Higher RC was associated with higher CVD mortality, which may be a better lipid indicator for estimating the CVD death risk in older adults.

ABSTRACT

BACKGROUND@#Both lung cancer and cardiometabolic diseases are leading causes of death in China, and they share some common risk factors. However, the prevalence and long-term effect of pre-existing cardiometabolic comorbidities (CMCs) on the survival of middle-aged and elderly lung cancer patients are still not clear.@*METHODS@#We consecutively recruited 3477 non-small cell lung cancer (NSCLC) patients between January 2011 and December 2018 from four cancer specialty hospitals in China. Univariable and multivariable adjusted Cox proportional hazard models were conducted to evaluate the risk factors associated with mortality. Hazard ratio (HR) for mortality and corresponding 95% CI were calculated.@*RESULTS@#The prevalence of CMCs was 30.0% in middle-aged NSCLC patients and 45.5% in elderly NSCLC patients. Log-rank analysis presented statistically significant differences in median survival time between patients with CMCs and without CMCs in both the middle-aged group (21.0 months vs. 32.0 months, P < 0.01) and the elderly group (13.0 months vs. 17.0 months, P = 0.01). Heart failure (HR = 1.754, 95% CI: 1.436-2.144, P < 0.001) and venous thrombus embolism (HR = 2.196, 95% CI: 1.691-2.853, P < 0.001) were independent risk factors for the survival of middle-aged NSCLC patients, while heart failure (HR = 1.709, 95% CI: 1.371-2.130, P < 0.001) continued to decrease overall survival in the elderly group. Hyperlipidemia may be a protective factor for survival in middle-aged group (HR = 0.741, 95% CI: 0.566-0.971, P = 0.030).@*CONCLUSIONS@#Our findings demonstrate for the first time the prevalence and prognostic value of pre-existing CMCs in Chinese middle-aged and elderly NSCLC patients.

ABSTRACT

ObjectiveTo explore the effect of Baitouweng Tang (BTWT) on the apoptosis of human colorectal cancer HCT116 cells and decipher the underlying mechanism based on the Hedgehog (Hh) signaling pathway. MethodHCT116 cells were treated with BTWT (25, 50, 100, 200, 500, 750, and 1 000 mg·L-1) for 24 h, and then the cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. Five groups were designed for the treatment of HCT116 cells, including a blank control group, BTWT groups (125, 250, and 500 mg·L-1), and a positive control (5-fluorouracil, 5-FU, 40 mmol·L-1) group. The cell morphology was observed under an inverted microscope. The migration of the cells was detected by scratch test, and the apoptosis by Hoechest 33324/propidium iodide (PI) staining and flow cytometry. Western blot was employed to determine the protein levels of sonic hedgehog (SHh), GLI family zinc finger protein 1 (Gli1), smoothened (Smo), suppressor of fused (SuFu), cellular-myelocytomatosis viral oncogene (c-Myc), and the apoptosis-related proteins B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax). The quantitative real-time reverse transcription PCR (Real-time PCR) was employed to determine the mRNA levels of Bax, Bcl-2, SHh, Gli1, Smo, SuFu, and c-Myc. ResultCompared with the blank control group, BTWT changed the cell morphology (making the cell become round with dense nucleus), inhibited the proliferation of HCT116 cells in a dose-dependent manner, decreased the ability of migration (P<0.05, P<0.01), and increased apoptotic cells. Compared with the blank control group, BTWT (500 mg·L-1) treatment for 24 h up-regulated the protein and mRNA levels of Bax (P<0.05, P<0.01) and down-regulated the protein and mRNA levels of Bcl-2 in HCT116 cells (P<0.05, P<0.01). Moreover, the treatment down-regulated the mRNA and protein levels of SHh, Gli1, Smo, and c-Myc (P<0.05, P<0.01) and up-regulated the mRNA and protein levels of SuFu (P<0.05, P<0.01). ConclusionBTWT inhibited the proliferation and migration and induced the apoptosis of colorectal cancer HCT116 cells by down-regulating the Hh signaling pathway.

ABSTRACT

Hyperplasia of mammary glands is a benign breast disease with disordered breast structure. Nowadays, the incidence rate of breast hyperplasia in women is increasing year by year, and the etiology is related to the imbalance of estrogen and progesterone in the body. The symptoms include breast pain, breast nodules, or nipple discharge, which can develop into breast cancer in the context of psychological pressure. Therefore, it is timely and effectively necessary for people to treat the symptoms. At present, traditional Chinese medicine(TCM) often treats breast hyperplasia by oral drug, external application, acupuncture, moxibustion, and massage, while western medicine often uses hormone therapy or surgery. TCM can regulate hormone levels to treat breast hyperplasia. Acupuncture, moxibustion, and other methods can stimulate acupoints to reduce breast lumps. However, since TCM is easy to produce hepatorenal toxicity after long-term use and simple external treatment is slow to take effect, rapid and effective treatment is difficult to be achieved. Although western medicine can inhibit the disease, it is easy to produce toxic and side effects if taken for a long time. In addition, surgery can only remove the focus and the recurrence rate is high. Some studies have found that the combination of oral and external use of TCM compounds has a significant effect, with mild toxic and side effects, few adverse reactions, and a low recurrence rate. Based on the relevant literature in recent years, this article reviewed the combination of oral and external treatment of TCM in the treatment of hyperplasia of mammary glands, discussed the effectiveness, clinical evaluation indexes, and mechanism, and pointed out the existing shortcomings to explore a comprehensive therapy worthy of clinical application.

ABSTRACT

ObjectiveTo systematically review the clinical experience of four sessions of Masters of Traditional Chinese Medicine and two sessions of National Famous Chinese Medicine Practitioners in treating ulcerative colitis (UC). Data mining and analysis were conducted to clarify the diagnosis and treatment ideas and characteristics of prescription used by these famous doctors in treating UC. MethodsRelevant literature on the treatment of UC by renowned doctors was retrieved from the establishment of the database until March 31, 2023. The literature was collected from databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, Chinese Science and Technology Periodicals Database, and China Biomedical Literature Database. The data mining techniques including frequency analysis, association rules, and cluster analysis were conducted using the Ancient and Modern Medical Case Cloud Platform V2.3.5. ResultsA total of 157 literatures were included in this study, including 115 clinical case data. The study found that UC can be categorized into 14 types of syndrome patterns for treatment, including large intestine dampness-heat syndrome (75,65.22%), syndrome of dampness stagnancy due to spleen deficiency (23, 20.00%), spleen-kidney yang deficiency syndrome (21, 18.26%). The main affected organs were the spleen (85, 73.91%) and large intestine (75, 65.22%), and they were closely related to liver (24, 20.87%) and the kidney (21, 18.26%). The predominant pathogenic factors were dampness (83, 72.17%) , heat (80, 69.57%) and qi deficiency (65, 56.52%). The treatment involved 30 kinds of treatment methods, including heat-clearing and dampness-draining method (75, 65.22%), pleen-tonifying and qi-boosting method (25,21.74%) and spleen-invigorating and dampness-transforming method (23, 20.00%). The medication involved 187 ingredients, with the most commonly used being heat-clearing herbs (37, 19.79%) and tonifying herbs (27, 14.44%). The tastes of the herbs were mostly sweet (85, 45.45%) , bitter (80, 42.78%) , and pungent (71, 37.97%). The association rules revealed 16 high-frequency combinations mainly composed of Huanglian (黄连), Baishao (白芍) and Gancao (甘草) along with Baizhu (白术), Fuling (茯苓), Muxiang (木香) and Danggui (当归). ConclusionFamous doctors are skilled in diagnosing and treating UC based on the differentiation of the zang-fu organs and qi-blood. The key pathological mechanism is “spleen deficiency as the root, and large intestine damp-heat as the manifestation”. The core treatment approach is “heat-clearing, spleen-tonifying, and dampness-draining”, with the inclusion of “regulating qi and blood, and balancing cold and heat”.

ABSTRACT

Objective:To explore the demand and actual supply of community-based care services for the elderly residents and the factors that affecting care mode for them in the context of rapid urbanization and population aging in China.Methods:Based on the cross-sectional data of the seventh China Longitudinal Survey on Health and Longevity(CLHLS)(2018), 15 854 elderly residents aged 60 and above were selected as the research population.Logistic regression method was used to analyze the patterns of community-based care services and their influencing factors.Results:Among 15 854 elderly residents, 6 912(43.60%)were male and 8 942(56.40%)were female.The results of activities of daily living(ADL)evaluation showed that 11 109 elderly residents could take care of themselves completely, and 3 889 elderly residents were disabled.The disability rate was 25.93%.The proportion of social services that elderly town dwellers expect the community to provide is higher than those living in cities and rural areas in terms of daily care, spiritual care, providing health care knowledge, and dealing with neighborhood disputes.From the perspective of social services actually provided by the community, in addition to providing home-based care, the proportion of community services available to the elderly living in towns and rural areas are similar, but significantly lower than the proportion of social services provided for elderly city dwellers.Age, marital status, residence, cultural differences, health status, source of life and living preference had significant impacts on the choice of care demand patterns.Those of older age( OR=2.29, 95% CI: 1.04-5.03 for 70-79 years old; OR=2.94, 95% CI: 1.38-6.25 for elderly 80 years old or above), having no spouse( OR=3.50, 95% CI: 2.49-4.92), and with higher levels of disability( OR=4.24, 95% CI: 3.12-5.77 for mild disability; OR=7.54, 95% CI: 5.19-10.95 for moderate disability; OR=10.50, 95% CI: 7.59-14.53 for severe disability)are more inclined to choose socialized care. Conclusions:In the process of rapid urbanization in China, the demands for care services of elderly living in towns has increased, but the actual care services provided for them by the communities are yet to be improved.Moreover, elderly town dwellers are still inclined to family care, the same as those of elderly rural dwellers.

ABSTRACT

【Objective】 To explore the correlation between CSAG1 expression and the prognosis and tumor-infiltrating lymphocytes in renal clear cell carcinoma (RCCC), and to predict the survival and tumor progression. 【Methods】 The gene expression profiles and clinical information of CSAG1 were downloaded from the Cancer Genome Atlas (TCGA). Based on the differential mRNA expression, GO annotation and KEGG pathway analysis were performed. The relationship between CSAG1 and tumor immune infiltration was assessed with Tumor Immunoassay Resource (Timer 2.0) database. The mRNA expression of CSAG1 in human RCCC specimens was validated with qRT-PCR. 【Results】 CSAG1 expression was significantly higher in RCCC tissues than in normal tissues (P<0.05). The qRT-PCR results revealed that the mRNA level of CSAG1 was consistent with that predicted by bioinformatic analysis. The KEGG analysis and GO annotation indicated high GSAG1 expression in RCCC was related to transmembrane transport, tricarboxylic acid cycle and lysosome. CSAG1 expression was positively related to the infiltration of pDC, aDC, CD8+ T cells, cytotoxic cells, TFH, TH1 cells, Tem, NK CD56dm cells, Treg and T cells, but negatively correlated with macrophage infiltration. 【Conclusion】 CSAG1 may be associated with poor prognosis of RCCC and become a potential immunotherapy target.

ABSTRACT

Increasing evidences suggest the important role of calcium homeostasis in hallmarks of cancer, but its function and regulatory network in metastasis remain unclear. A comprehensive investigation of key regulators in cancer metastasis is urgently needed. Transcriptome sequencing (RNA-seq) of primary esophageal squamous cell carcinoma (ESCC) and matched metastatic tissues and a series of gain/loss-of-function experiments identified potassium channel tetramerization domain containing 4 (KCTD4) as a driver of cancer metastasis. KCTD4 expression was found upregulated in metastatic ESCC. High KCTD4 expression is associated with poor prognosis in patients with ESCC and contributes to cancer metastasis in vitro and in vivo. Mechanistically, KCTD4 binds to CLIC1 and disrupts its dimerization, thus increasing intracellular Ca2+ level to enhance NFATc1-dependent fibronectin transcription. KCTD4-induced fibronectin secretion activates fibroblasts in a paracrine manner, which in turn promotes cancer cell invasion via MMP24 signaling as positive feedback. Furthermore, a lead compound K279-0738 significantly suppresses cancer metastasis by targeting the KCTD4‒CLIC1 interaction, providing a potential therapeutic strategy. Taken together, our study not only uncovers KCTD4 as a regulator of calcium homeostasis, but also reveals KCTD4/CLIC1-Ca2+-NFATc1-fibronectin signaling as a novel mechanism of cancer metastasis. These findings validate KCTD4 as a potential prognostic biomarker and therapeutic target for ESCC.

ABSTRACT

Objective: To evaluate the long-term efficacy and safety of the implantable ventricular assist system EVAHEART I in clinical use. Methods: Fifteen consecutive patients with end-stage heart failure who received left ventricular assist device therapy in Fuwai Hospital from January 2018 to December 2021 were enrolled in this study, their clinical data were retrospectively analyzed. Cardiac function, liver and kidney function, New York Heart Association (NYHA) classification, 6-minute walk distance and quality of life were evaluated before implantation and at 1, 6, 12, 24 and 36 months after device implantation. Drive cable infection, hemolysis, cerebrovascular events, mechanical failure, abnormally high-power consumption and abnormal pump flow were recorded during follow up. Results: All 15 patients were male, mean average age was (43.0±7.5) years, including 11 cases of dilated cardiomyopathy, 2 cases of ischemic cardiomyopathy, and 2 cases of valvular heart disease. All patients were hemodynamically stable on more than one intravenous vasoactive drugs, and 3 patients were supported by preoperative intra aortic balloon pump (IABP). Compared with before device implantation, left ventricular end-diastolic dimension (LVEDD) was significantly decreased ((80.93±6.69) mm vs. (63.73±6.31) mm, P<0.05), brain natriuretic peptide (BNP), total bilirubin and creatinine were also significantly decreased ((3 544.85±1 723.77) ng/L vs. (770.80±406.39) ng/L; (21.28±10.51) μmol/L vs. (17.39±7.68) μmol/L; (95.82±34.88) μmol/L vs. (77.32±43.81) μmol/L; P<0.05) at 1 week after device implantation. All patients in this group were in NYHA class Ⅳ before implantation, and 9 patients could recover to NYHA class Ⅲ, 3 to class Ⅱ, and 3 to class Ⅰ at 1 month after operation. All patients recovered to class Ⅰ-Ⅱ at 6 months after operation. The 6-minute walk distance, total quality of life and visual analogue scale were significantly increased and improved at 1 month after implantation compared with those before operation (P<0.05). All patients were implanted with EVAHEART I at speeds between 1 700-1 950 rpm, flow rates between 3.2-4.5 L/min, power consumption of 3-9 W. The 1-year, 2-year, and 3-year survival rates were 100%, 87%, and 80%, respectively. Three patients died of multiple organ failure at 412, 610, and 872 d after surgery, respectively. During long-term device carrying, 3 patients developed drive cable infection on 170, 220, and 475 d after surgery, respectively, and were cured by dressing change. One patient underwent heart transplantation at 155 d after surgery due to bacteremia. Three patients developed transient ischemic attack and 1 patient developed hemorrhagic stroke events, all cured without sequelae. Conclusion: EVAHEART I implantable left heart assist system can effectively treat critically ill patients with end-stage heart failure, can be carried for long-term life and significantly improve the survival rate, with clear clinical efficacy.

ABSTRACT

Cancer immunotherapy has become a promising strategy. However, the effectiveness of immunotherapy is restricted in "cold tumors" characterized with insufficient T cells intratumoral infiltration and failed T cells priming. Herein, an on-demand integrated nano-engager (JOT-Lip) was developed to convert cold tumors to hot via "increased DNA damage and dual immune checkpoint inhibition" strategy. JOT-Lip was engineered by co-loading oxaliplatin (Oxa) and JQ1 into liposomes with T-cell immunoglobulin mucin-3 antibodies (Tim-3 mAb) coupled on the liposomal surface by metalloproteinase-2 (MMP-2)-sensitive linker. JQ1 inhibited DNA repair to increase DNA damage and immunogenic cell death (ICD) of Oxa, thus promoting T cells intratumoral infiltration. In addition, JQ1 inhibited PD-1/PD-L1 pathway, achieving dual immune checkpoint inhibition combining with Tim-3 mAb, thus effectively promoting T cells priming. It is demonstrated that JOT-Lip not only increased DNA damage and promoted the release of damage-associated molecular patterns (DAMPs), but also enhanced T cells intratumoral infiltration and promoted T cell priming, which successfully converted cold tumors to hot and showed significant anti-tumor and anti-metastasis effects. Collectively, our study provides a rational design of an effective combination regimen and an ideal co-delivery system to convert cold tumors to hot, which holds great potential in clinical cancer chemoimmunotherapy.

ABSTRACT

BACKGROUND@#Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed.@*OBJECTIVE@#To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs.@*SEARCH STRATEGY@#Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review."@*INCLUSION CRITERIA@#SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs.@*RESULTS@#A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm.@*CONCLUSION@#The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

ABSTRACT

Objective:To establish a differential diagnosis model for IgA nephropathy and non-IgA nephropathy based on machine learning algorithms.Methods:Retrospective study adopted,from 2019 to 2020,260 patients were referred to the Department of Nephrology at the First Affiliated Hospital of Kunming Medical University, the First People′s Hospital in Yunnan province, and Yan′an Hospital of Kunming city. All patients were diagnosed by renal pathology, 130 cases of primary IgA nephropathy, the 130 cases of non-IgA nephropathy. Collection of materials, including gender and age, 28 clinical data, and routine laboratory test results,the sex ratio of IgA nephropathy group and non-IgA nephropathy group were 59∶71 and 64∶66 respectively, the ages were 37.20 (21.89, 53.78) and 43.30 (27.77, 59.18) years, respectively. 260 patients were divided into a training set (70%, 182 cases) and a test set (30%, 78 cases). Using the decision tree, random forests, support vector machine, extreme gradient boosting to establish a differential diagnosis model for IgA nephropathy and non-IgA nephropathy. Based on the true positive rate, true negative rate, false-positive rate, false-negative rate, accuracy, subjects features work area under the curve(AUC), the precision ratio, recall ratio, and F1 score, comprehensively evaluate the performance of each model, finally, the best performance of the model was chosen. Using SPSS 25.0 to analyze the data, P<0.05 was considered to be statistically significant. Results:The accuracy of the decision tree, support vector machine, random forests and extreme gradient boosting establish differential diagnosis model was 67.95%, 70.51%, 80.77% and 83.33%, respectively; AUC values was 0.74, 0.76, 0.80 and 0.83; Judgment for primary IgA nephropathy F1 score was 0.73, 0.72, 0.80 and 0.83, respectively. The efficiency of the extreme gradient boosting model based on the above evaluation indicators is the highest, its diagnosis of IgA nephropathy of the sensitivity and specificity respectively 89% and 79%. The variable importance from high to low was blood albumin, IgA/C3, serum creatinine, age, urine protein, urine albumin, high-density lipoprotein cholesterol, urea.Conclusion:The differential diagnosis model for IgA nephropathy was established successfully and non-IgA nephropathy and the efficiency performance of the extreme gradient boosting algorithm was the best.

ABSTRACT

Colorectal cancer (CRC) is a common malignancy burdening people globally, with increasing morbidity and mortality nowadays, due to the alternation in the diet type and lifestyle in modern society. Berberine, a type of benzylisoquinoline alkaloid, is widely present in numerous medicinal plants, particularly including Coptidis Rhizoma. Mounting evidence reveals that berberine possesses an array of pharmacological effects, such as anti-inflammation, anti-bacterium, anti-cancer, anti-diabetes mellitus and so on. In particular, berberine exhibits substantial inhibition on various types of cancers including CRC. Hereby, we sought to systematically review the suppressive effect of berberine on CRC through the diminishment of the proliferation and metastasis, induction of apoptosis, arrest of cell cycle, regulation of inflammatory reaction, the reverse of chemotherapeutic resistance and restoration of gut microbiota in CRC, so as to shed light on the in-depth mechanisms underlying the treatment of CRC with berberine in the clinical setting.

ABSTRACT

ObjectiveTo evaluate the effect and safety of Buyang Huanwutang in treatment of connective tissue disease-associated pulmonary fibrosis in the patients with syndrome of Qi deficiency and blood stasis and explore the possible anti-fibrosis mechanism of Buyang Huanwutang. MethodSixty-six patients with connective tissue disease-associated pulmonary fibrosis with syndrome of Qi deficiency and blood stasis were randomized to receive either Buyang Huanwutang combined with routine therapy or routine therapy for 4 weeks. The primary outcome indicator was change in forced vital capacity (FVC) from the baseline, and the secondary outcome indicators included the changes in percentage of predicted forced vital capacity (FVC%pred), percentage of forced expiratory volume in first second to predicted value (FEV1%pred), King's Brief Interstitial Lung Disease (K-BILD) total score, 6 minute walking distance (6MWD), hydroxyproline (HYP), matrix metalloproteinase (MMP), tissue inhibitor of metalloproteinase-1 (TIMP-1), and transforming growth factor-β (TGF-β) from baseline. Patients in line with the inclusion criteria were included in the primary analysis, and sensitivity analysis was performed after multiple imputation of missing data. Safety set was adopted for safety analysis. ResultThe 66 patients (included in the sensitivity analysis) meeting the inclusion criteria included 34 in the observation group and 32 in the control group, and 60 patients finally received the whole trial intervention (included for primary analysis). Compared with the baseline, the FVC increased in the observation group and decreased in the control group after intervention (P<0.01), which was consistent between the sensitivity analysis and the primary analysis. The changes in FVC%pred, FEV1%pred, 6MWD, and K-BILD total score from baseline in the observation group were superior to those in the control group (P<0.01), with consistent results between the sensitivity analysis and the primary analysis. TIMP-1 in the observation group decreased compared with baseline (P<0.05), while TIMP-1 in the two groups showed no significant changes from the baseline The observation group outperformed the control group in the changes in HYP, MMP-9, and TGF-β from baseline (P<0.05). The common adverse events were cough, diarrhea, nausea, rash, and upper gastrointestinal tract infection, the incidence of which showed no statistical difference between the two groups. ConclusionBuyang Huanwutang can improve lung function, motor function, and quality of life in patients with connective tissue disease-associated pulmonary fibrosis and has good safety. The mechanism may be related to the reduction of TGF-β, MMP-9, and TIMP-1 levels and maintaining of MMP-9/TIMP-1 balance.
