Objective To explore the effect of vitamin B on the treatment of senile vaginitis .Methods A total of 124 pa-tients suffered senile vaginitis were included in the study , who were accepted the treatment of compound metronidazole suppositories and estriol cream.By simple randomization,the patients accepted the treatment of vitamin B were divided into the observe group and control group.The difference of the clinical efficacy, symptoms and signs and recurrence rate were compared between the two groups.Results ①There′s no significant difference of total effective rate between the observed group(93.55%) and the control group(88.71%)(P>0.05).②After treatment, the increased secretion, vaginal itching, vaginal burning, vaginal wall congestion and secretions microscope cleanliness were significantly improved than that before the treatment in both of the groups(P<0.01).③The recurrence rate in the observed group(24.24%) was significantly lower than the control group (60%).Conclusion Vitamin B could improve the symptoms and reduce relapse rate of senile vaginitis .

Non-alcoholic fatty liver disease (NAFLD) is characterized by increased fat depositions in the liver while the patients do not have drinking history.NAFLD has a prevalence of 10％ ～40％ in global,25％ ～26％ in Western populations.From 2004 to 2013,the numbers of new patients on the waitlist who had NASH increased by 170％ in America.The prevalence of NAFLD in China is 20％.With the decrease of HBV and HCV and the increase of diabetes mellitus type 2 and obesity,NAFLD will become the most common chronic liver disease in China over the next 20 years.NAFLD related end-stage liver disease will become the most common indication of liver transplantation.In this paper,the epidemiological features,pathogenesis,indication and prognosis of liver transplantation are reviewed.

Objective:To explore the endoscopic features of early gastric cancer (EGC) related to non-curative endoscopic resection, and to construct an assessment model to quantify the risk of non-curative resection.Methods:From August 2006 to October 2019, 378 lesions that underwent endoscopic resection and were diagnosed pathological as EGC in the Department of Gastroenterology, Peking Union Medical College Hospital were included in this case-control study.Seventy-eight (20.6%) non-curative resection lesions were included in the observation group, and 234 lesions which selected from 300 lesions of curative resection were included in the control group according to the difference of operation year ±1 with the observation group, and the ratio of 1∶3 of the observation group to the control group. Univariate and multivariate logistic regression analysis were performed to explore the risk factors for non-curative resection. The independent risk factor with the minimum β coefficient was assigned 1 point, and the remaining factors were scored according to the ratio of their β coefficient to the minimum. A predictive model was established to analyze the 378 lesions.The non-curative resection rates of lesions of different scores were calculated. Results:Univariate analysis showed that the lesion diameter, the location, redness, ulcer or ulcer scar, fold interruption, fold entanglement, and invasion depth observed with endoscopic ultrasonography (EUS) were associated with non-curative resection of EGC lesions ( P<0.05), and contact or spontaneous bleeding may be associated with non-curative resection ( P=0.068). Multivariate logistic regression analysis showed that submucosal involvement (VS confined to the mucosa: β=0.901, P=0.011, OR=2.46, 95% CI: 1.23-4.92), lesion diameter of 3-<5 cm (VS <3 cm: β=0.723, P=0.038, OR=2.06, 95% CI: 1.04-4.09), lesion diameter of ≥5 cm (VS <3 cm: β=2.078, P=0.003, OR=7.99, 95% CI: 2.02-31.66), location in the upper 1/3 of the stomach (VS lower 1/3: β=1.540, P<0.001, OR=4.66, 95% CI: 2.30-9.45), and fold interruption ( β=2.287, P=0.008, OR=1.93, 95% CI: 0.95-3.93) were independent risk factors for non-curative resection of EGC lesions. The factor of lesion diameter of 3-<5 cm and submucosal involvement were assigned 1 point respectively, location in the upper 1/3 of the stomach was assigned 2 points, diameter of ≥5 cm and fold interruption were assigned 3 points respectively, and other factors were assigned 0 point. Then the analysis of 378 lesions showed that the probability of non-curative resection at ≥2 points was 41.9% (37/93), 4 times as much as that at 0 [11.5% (25/217)]. Conclusion:EGC lesions with diameter ≥3 cm, located in the upper 1/3 of the stomach, interrupted folds or submucosal involvement are highly related to non-curative resection. The predictive model based on these factors achieves satisfactory efficacy, but it still needs further validation in larger cohorts.

OBJECTIVE： To investigate the protective effect of total flavonoids from the leaves of Choerospondias axillaris （TFLC） on myocardial ischemia reperfusion injury （MIRI） model rats. METHODS： Male SD rats were randomly divided into sham operation group， model group， positive control group （verapamil， 0.02 g/kg）， TFLC low-dose and high-dose groups （0.1， 0.4 g/kg）， with 10 rats in each group. Administration groups were intragastrically given relevant medicine （2 mL/100 g）； sham operation group and model group were given constant volume of normal saline intragastrically， once a day， for consecutive 7 d. After last medication， MIRI model was induced by modified ligation method. The times and duration of ventricular tachycardia （VT） and ventricular fibrillation （VF） in rats were recorded with biological function experiment system during reperfusion period.The activity of CK and contents of TNF-α， IL-6， NF-κB and NO in serum were determined by ELISA double antibody clip art assay. The morphological characteristics of myocardial tissue was observed by HE staining. The myocardial infarction scope （i.e. the ratio of myocardial tissue mass to ventricular mass） was measured by TTC method. RESULTS： Compared with sham operation group， the times and duration of VT and VF were increased or prolonged significantly in model group； CK activity， serum contents of TNF-α， IL-6 and NF-κB were enhanced or increased significantly， while NO content was decreased significantly （P＜0.05 or P＜0.01）. Obvious myocardial infarction focus， serious cell structure damage， disorderly muscle fibers arrangement， cell nucleus pyknosis and accompanied inflammatory cell infiltration were all observed in cardiac tissue； the mass of infarcted myocardial tissue and ventricular as well as the scope of myocardial infarction increased significantly （P＜0.01）. Compared with model group， the times and duration of VT and VF were decreased or shortened significantly in administration groups； CK activity， serum contents of TNF-α， IL-6， NF-κB were decreased significantly， while NO content was increased significantly （P＜0.05 or P＜0.01）. The above symptoms of myocardial injury were improved；the mass of infarcted myocardial tissue and ventricular as well as the scope of myocardial infarction was significantly reduced （P＜0.05 or P＜0.01）. CONCLUSIONS： TFLC can relieve MIRI-induced ischemic arrhythmia and myocardial damage， reduce the release of inflammatory factors， promote the recovery of myocardial and endothelial cell function， reduce the scope of myocardial infarction and has a certain protective effect.
