Notes

Prognostic valuation on BRAF and KRAS mutation position within period 2 as well as 3 microsatellite instable digestive tract cancers.
Patients in both groups will be evaluated weekly for efficacy during the intervention. The primary efficacy indicators include the types of wound pathogens, interleukin 6 and tumor necrosis factor α. Secondary efficacy indicators included blood glucose, blood lipids, wound area, lower extremity blood vessel diameter, blood flow speed, walking speed, walking distance, and traditional Chinese medicine syndrome scores. We will also conduct a safety evaluation of the drug at the end of the trial. DISCUSSION This multicenter, double-blind, randomized, placebo clinical trial not only provides data on the efficacy and safety of FBD, but also provides a novel treatment strategy for clinicians and DF patients.The present study was designed to investigate the expression of tumor-associated macrophages (TAMs) in gastric cancer and its clinicopathological relationship. In addition, we also aimed to analyze the relationship between helicobacter pylori (HP) infection and TAMs in gastric cancer.The protein expression of CD16 and CD163 in 90 gastric cancer tissues and 30 margin tissues was detected by immunohistochemistry. Captisol HP infection was detected in 90 gastric cancer tissues and 30 margin tissues by gram staining and immunohistochemistry.There was no clear correlation between CD16 macrophages and gastric cancer. The density of CD163 macrophages was not correlated with the general condition of tumor patients, but with tumor size, tumor differentiation, lymphatic metastasis, depth of invasion and TNM stage. Additionally, the infection rate of HP in gastric cancer tissues was significantly higher.In summary, TAMs are associated with tumor size, degree of differentiation, depth of invasion, lymph node metastasis and TNM stage, suggesting their critical role in the invasion and metastasis of gastric cancer.BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) occurs in 68.1% of patients within the first month of undergoing chemotherapy; however, standardized treatment for CIPN has not been established yet. The efficacy of acupuncture, a widely used treatment for CIPN in South Korea, has not been studied sufficiently. This study aimed to review the studies that evaluated the efficacy of acupuncture or electroacupuncture (EA) in treating CIPN. METHODS A literature search was performed on relevant international databases - MEDLINE, Embase, the Allied and Complementary Medicine Databases, and China National Knowledge Infrastructure - as well as Korean databases - the National Digital Science Library, Oriental Medicine Advanced Searching Integrated System, DBpia, and Korean Studies Information Service System. Randomized controlled trials (RCTs) that aimed to treat CIPN symptoms with acupuncture or EA and set not only a control group with a conventional pharmacological treatment or injection, but also a placeb CRD42018111509.The study aimed to investigate the association between the risk of hepatocellular carcinoma and thiazolidinediones use among type 2 diabetic patients who had risk factors for hepatocellular carcinoma.A population-based case-control study was performed using the database of the Taiwan National Health Insurance Program. The cases consisted of 23580 type 2 diabetic subjects aged 20 to 84 years with newly diagnosed hepatocellular carcinoma between 2000 and 2011. The sex- and age-matched controls consisted of 23580 randomly selected type 2 diabetic subjects without hepatocellular carcinoma between 2000 and 2011. Ever use of thiazolidinediones was defined as subjects who had at least 1 prescription of thiazolidinediones before the index date. Never use of thiazolidinediones was defined as subjects who did not have a prescription of thiazolidinediones before the index date. The odds ratio and 95% confidence interval for the association between hepatocellular carcinoma and cumulative duration of thiazolidinediones use was measured by a multivariable logistic regression model.Among subjects with any 1 of the comorbidities including alcohol-related disease, cirrhosis, hepatitis B infection, hepatitis C infection, and other chronic hepatitis, a multivariable logistic regression model demonstrated that there was a negative association between hepatocellular carcinoma and every 1-year increase of cumulative duration of thiazolidinediones use (adjusted odds ratio 0.94, 95% confidence interval 0.92-0.97).There was a negative association in a duration-dependent manner between the risk of hepatocellular carcinoma and thiazolidinediones use among type 2 diabetic patients who had risk factors for hepatocellular carcinoma.BACKGROUND Human parvovirus B19 (B19V) infection exhibits a broad range of clinical outcomes. Blood transfusion is a common route of B19V transmission. However, information about the overall prevalence of B19V infection and B19V genotypes among blood donors in mainland China is lacking. METHODS This meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search for studies reporting the B19V prevalence among blood donors in mainland China from 2000 to 2018 was performed. The prevalence of B19V was estimated through a meta-analysis of the relevant literature. A comprehensive meta-analysis program was used for data processing and statistical analysis. RESULTS Twenty-one eligible articles were included, involving 48,923 participants assessed for B19V-DNA, 12,948 participants assessed for anti-B19V immunoglobulin M (IgM), and 8244 participants assessed for anti-B19V immunoglobulin G (IgG). The analysis revealed the pooled estimates of the prevalence rates of B19V-DNA, anti-B19V IgM, and anti-B19V IgG among blood donors to be 0.7% (95% confidence interval [CI] 0.2-2.4%), 2.7% (95% CI 1.7-4.3%), and 33.6% (95% CI 28.2-39.4%), respectively. Moreover, phylogenetic analyses indicated that 142 of 169 (84.0%) B19V isolates belonged to Genotype 1. CONCLUSIONS The overall prevalence of B19V among blood donors is not high in mainland China, and most isolates belong to Genotype 1.BACKGROUND AND AIM Aortic valve (AV) cusp prolapse and subsequent aortic insufficiency (AI) are 2 of factors leading to left ventricular (LV) enlargement and decreased LV function. Aortic valve replacement (AVR) has been the standard surgical procedure for AI. However, few data is available on the prognosis of these patients undergoing AVR procedure, especially in Chinese population. The study aims to evaluate the potential risk factors affecting the mid-term adverse outcomes after AVR. METHODS One hundred thirty-four patients (mean age 46.7 years old) with AV cusp prolapse and severe AI who all received surgical aortic valve replacement were recruited in our hospital between January 1, 2009 and December 30, 2017. The clinical characteristics, echocardiography parameters, as well as operative parameters were obtained. The primary endpoint included death, heart failure development, and reoperation. RESULTS There were 14 adverse events altogether with the primary endpoint during a median follow-up of 8.6 (6-10) months. The multivariable Cox regression analysis revealed that baseline LVEDD (hazard rate, HR = 1.08, 95% CI 1.01-1.15, P = .021), moderate pulmonary hypertension (HR = 9.36, 95% CI 1.81-48.28, P = .008), and the time of assisted mechanical ventilation (HR = 1.01, 95% CI 1.00-1.01, P = .022) were independently associated with the primary endpoint. Kaplan-Meier survival curve showed a significant worse survival free of the endpoint for patients with LVEDD≥70 mm, indexed LVEDD≥37.3 mm/m (the mean in this study), indexed LVESD≥25 mm/m or baseline LVEF less then 50% (all P less then .05). CONCLUSION Baseline enlarged LV dimensions, low LV function, moderate pulmonary hypertension, and prolonged assisted mechanical ventilation may predict the poor mid-term postoperative outcomes for AV cusp prolapse patients undergoing AVR procedure.BACKGROUND Road traffic injuries (RTIs) have become a considerable issue for children. In China, RTIs are among the top 3 contributors to injury-related mortality and disability-adjusted life years. The present study aimed to evaluate social and environmental factors that may contribute to RTIs among children under 5 in rural areas of China. METHODS The study was based on 1 year of data (October 1, 2015 to September 30, 2016) from the National Maternal and Child Health Surveillance System (NMCHSS) from all districts in 334 National Maternal and Child Health Surveillance Districts in 30 Chinese provinces, autonomous regions, and municipalities. Data were analyzed to identify environmental, social, and primary caregiver factors related to RTIs among children under 5. RESULTS Based on data for the 279 children registered in the NMCHSS during the study period, incidence of RTIs increased with increasing age and was higher for boys than girls. Risk of RTIs depended on distances from the child's home to roads and playgrounds. Enrollment in kindergarten and characteristics of primary caregivers affected risky road behaviors by children. Most primary caregivers (67.4%) reported never using child car seats, and 70.6% reported never using a child helmet. Among primary caregivers without a driver's license, 24.8% reported having driven motor vehicles or motorcycles. CONCLUSIONS The living environment and behaviors of primary caregivers can affect risk of RTIs in children younger than 5 years in rural China. Road safety awareness should be strengthened at the community and kindergarten levels.BACKGROUND Constipation is a frequent gastrointestinal symptom. It is intimately related to many diseases. 1st-line therapy can not alleviate constipation for some patients. Alternative treatments are therefore commonly used, such as probiotics. Nevertheless, the efficacy and safety of probiotics used as a single treatment are still uncertain. A systematic review and meta-analysis will be carried out to answer the issue. METHODS The protocol accompanied Preferred Reporting Items for Systematic Reviews and Protocol Meta-Analysis. PubMed, Cochrane, Embase, and Web of Science databases were practiced for randomized controlled trials without language constraint. In addition, We have also conducted backward (manually) and forward (with Google Scholar) citation checks to identify any additional relevant papers.Two reviewers will conduct studies selection, data extraction, and risk of bias assessment independently. The primary outcome is treatment success (spontaneous bowel movements (sBMs) >3 times per week), defecation frequency. The second result will be consistency, fecal incontinence, other symptoms (e.g. flatulence, abdominal pain), and adverse event rates and types. RESULTS This study provides helpful information about whether probiotics can be used as a single therapy on functional constipation CONCLUSION The findings of the review will be disseminated through peer-review publications.Previous studies have shown androgen receptor (AR) is associated with the occurrence, development, recurrence, metastasis, and prognosis of triple negative breast cancer (TNBC). More and more experts have noticed that AR signaling pathway plays an important role in the occurrence and development of TNBC. The purpose of this study is to detect the inhibitory efficacy and mechanism of Bicalutamide on the proliferation and invasion of TNBC cells.MDA-MB-231 cells of human breast cancer cells were treated with 0, 25, 100 μmol/L of Bicalutamide, cell proliferation assay was performed to assess cell proliferation viability by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, Thiazolyl Blue Tetrazolium Bromide assay and cell invasion was evaluated by Transwell assay. Meanwhile, flow cytometric analysis and western blotting were performed to investigate the mechanism of Bicalutamide on the proliferation and invasion of MDA-MB-231 cells.Bicalutamide could efficiently inhibit the proliferation and invasion of MDA-MB-231 cells in a dose-dependent manner.
