ABSTRACT
Objective:To analyze the efficacy evaluation criteria of the existing TCM treatment for edema RCT research, and to provide reference for the construction of unified standards.Methods:The batabases CNKI, WanFang Data, VIP, CBM, Pubmed and Web of Science were retrieved. The randomized controlled trials for the treatment of edema of TCM research, from September 1, 1993 to July 31, 2022, were screened and included. The content of efficacy evaluation, performed statistics on evaluation standard, the curative effect evaluation indexes, as well as standard composition, usage were extracted. We analyzed the characteristics, application and problems of the existing efficacy evaluation criterion.Results:A total of 123 Chinese articles were included. The included literature involved nephrogenic edema, cardiogenic edema, idiopathic edema, apoplexy limb edema and other edema. In recent years, randomized controlled trials on the treatment of edema by TCM have mainly used four efficacy evaluation criteria. Of which the Guidelines for Clinical Research on New Chinese Medicines (Trial) in 2002 had the highest utilization rate of 29.27%. Secondly, the utilization rate of Standard for Diagnosis and Curative Effect of TCM Diseases and Syndromes was 21.14%. The rest of the criteria were used by less than 6%. While 39.02% of the literature did not use the standards or used self-designed standards. Among the composition of efficacy evaluation indices, the application rate of TCM syndrome or symptom efficacy index was the highest (91.87%), the utilization rate of the Minnesota Living with Heart Failure Questionnaire Indicators was only 4.88%; biochemical tests accounted for a large proportion of Western medical indicators, while the measurement of edema severity was rarely applied. Conclusions:At present, the evaluation criteria of edema curative effect are diversified and insufficiently popularized, which need to be further screened and improved. It is suggested to construct a TCM edema efficacy evaluation model based on the characteristics of edema syndrome, comprehensively evaluate the efficacy from multiple dimensions such as TCM syndromes, western medicine indicators, and quality of life, and improve the scientific indicators.
ABSTRACT
Objective:Applying bibliometrics to analyze the research history, hotspots and trends of Traditional Chinese Medicine (TCM) interventions in edema-related diseases, and to provide reference for the revision of diagnostic and therapeutic criteria for edema in TCM.Methods:The literature about edema treated with TCM was retrieved from CNKI, Wanfang, VIP, CBM from 1 st. Jan 1995 to 25 th. May 2022. CiteSpace and VOSviewer softwares were used to draw the knowledge map, and analyze the co-occurrence relationship and clustering characteristics of the institution, author, keywords and mechanism hotspots. Results:Totally 3 198 articles were included. The annual number of documents issued generally shows a spiral rise trend. Liaoning University of Chinese Medicine published the most articles. Core authors published the most articles were Sun Wei (13 articles); the team with the highest cooperation intensity was Yang Hongtao's team; keywords formed 7 clusters. Hotspot mechanisms included metabolic disorders, immune balance, anti-inflammation, calcium and phosphorus metabolism. Keywords in the past 7 years were membranous nephropathy, chronic heart failure, diabetes, lymphedema etc.Conclusions:The attention paid to the intervention of TCM in the field of edema is generally on the rise, and has decreased in the past two years. The research categories focus on the experience of famous doctors, clinical trials, and mechanistic studies, and nephropathy-related edema has been the focus of research; diabetic nephropathy, chronic heart failure, metabolomics, and immunotherapy are expected to be the focus of attention in the next stage.
ABSTRACT
Objective:The unilateral (left) ureteral obstruction (UUO) model was established in mice to explore the changes of renal injury with time and the related mechanisms.Methods:Fifty mice were randomly divided into two groups: sham group and UUO group (UUO model was made by unilateral ureteral ligation). The biochemical indexes, left kidney weight/final weight (LR/BW) and right kidney weight/final weight (RR/BW) of the two groups at different time points were observed, and the left kidney weight/right kidney weight ratio (LR/RR) was calculated. Hematoxylin-eosin (HE), Masson and periodic acid-Schiff (PAS) staining were used to detect the pathological changes of the kidney in mice. Immunofluorescence staining was used to observe the loss of peritubular capillaries (PTC), proliferation of renal parenchymal cells (Ki67 + cells), macrophages (CD68 + markers), infiltration of fibroblasts and expression of Wnt/β-catenin in the kidney of mice. Results:The weight of mice in UUO group decreased rapidly [(18.2±1.1)g vs (22.4±1.2)g] on the third day of modeling, then slowly increased until the 28th day, and significantly decreased [(17.5±0.8)g] on the 60th day; LR/RR and LR/BW increased significantly in the third day, and then decreased gradually; Renal function of mice in UUO group deteriorated significantly on the 60th day [serum creatinine (0.89±0.09)mg/dl, urea nitrogen (41.26±5.65)mg/dl]. In UUO group, renal tubulointerstitial fibrosis and glomerulosclerosis were observed under light microscope in the obstructed kidney; with the passage of time, PTC loss gradually increased; macrophages increased significantly in the left renal parenchyma at first, but began to decrease 28 days later; the number of fibroblasts increased significantly in the first 14 days of the obstructed side (left side) kidney, and then decreased to the normal level; There was no significant difference in the cell number of the non obstructive kidney between UUO group and sham group; The immunofluorescence intensity expression of Wnt/β- catenin of obstructive side (left side) in UUO group was significantly up-regulated in the first 14 days after renal injury, and decreased after 28 days.Conclusions:The development of UUO renal fibrosis involves many changes, including PTC loss, macrophage infiltration, fibroblast activation and expression, but these changes weaken with time.
ABSTRACT
Objective@#To understand the current situation of sexual knowledge, attitudes and behaviors of young children in kindergarten, based on the framework of comprehensive sexuality education.@*Methods@#Totally 354 children between the ages of 3-6 from two kindergartens in Changping District, Beijing, participated in one-to-one interviews. There were 164 girls and 190 boys.@*Results@#In the dimension of physical development, no child knew the scientific name of reproductive organs. In the dimension of social emotion, 44.07% of children could express love to their friends, and 40.68% of children could express their refusal when they were unwilling. In the dimension of sexual health, well-being and sexual rights，81.92% of children knew that they couldn t touch other people s genitals, and 54.80% of children could at least name one way to protect themselves when facing sexual abuse. In the dimension of gender equality, 33.62% and 28.53%of children had gender stereotypes in toy selection and career choice, 66.38% of children thought that boys are as smart as girls. In the dimension of pregnancy and birth，78.53% of children knew where babies come from and 26.27% of children think parenthood doesn t directly lead to happiness. Sexual knowledge, attitudes and behaviors of children had statistically significant difference in different grades（P<0.05).@*Conclusion@#Children already have good understanding about pregnancy, childbirth and prevention of sexual abuse. In the future, sexuality education in school and family need to promote physical cognition and gender equality education.
ABSTRACT
Objective:To investigate the relationship between TP53 gene mutation and overall survival (OS) time of myelodysplastic syndrome (MDS).Methods:Databases, including PubMed, Cochrane Library and Embase were searched for relevant studies published up to 20 October, 2019. The corresponding hazard ratio ( HR) and their 95% confidence interval ( CI) for OS from multivariate Cox proportional hazard models were extracted. The combined HR with their 95% CI was calculated by using fixed or random effect models. Meta-analysis was performed by using Revman 5.3 software. Results:A total of 1 033 patients from 6 studies were enrolled. Meta-analysis results showed that OS time in TP53 gene mutation group was shorter than that in wild type group for patients with MDS ( HR = 2.16, 95% CI 1.52-3.07, P < 0.01). The prognostic risk for post-transplantation patients with MDS ( HR = 2.69, 95% CI 1.63-4.43, P < 0.01) was lower compared with that for patients treated by azacitidine( HR = 2.89, 95% CI 1.37-6.08, P = 0.005). Conclusion:TP53 gene mutation is a risk factor affecting OS of MDS patients.
