ObjectiveTo observe the efficacy of Chaowei Zhikangyin in the treatment of the rat model of non-alcoholic fatty liver disease (NAFLD). MethodsA rat model of NAFLD was established by feeding 50 Sprague-Dawley rats with high-fat diet for 6 weeks and was confirmed by liver pathological examination. Then, the model rats were randomly divided into five groups: low-, medium-, and high-dose Chaowei Zhikangyin groups (given Chaowei Zhikangyin by gavage), Kezhi capsule treatment group (given a suspension of Kezhi capsules), and model group (orally given distilled water). In addition, control rats were fed with normal diet and then treated with distilled water. Six weeks later, the liver function, blood lipids, liver lipids, and liver histology were examined. ResultsAll Chaowei Zhikangyin groups were superior to the model group in terms of alanine aminotransferase, aspartate aminotransferase, total cholesterol (TC), and triglyceride (TG) in serum and TC and TG in liver tissues (P＜0.05), but there were no significant differences between these Chaowei Zhikangyin groups and Kezhi capsule treatment group (P＞0.05). Different degrees of liver inflammation was observed in the model group and Chaowei Zhikangyin groups; however, the Chaowei Zhikangyin groups and Kezhi capsule treatment group had reduced liver inflammation compared with the model group (P＜0.05), and the Kezhi capsule treatment group showed a significantly more improvement than these Chaowei Zhikangyin groups (P＜0.05). ConclusionChaowei Zhikangyin can improve liver function, reduce blood lipids, and inhibit liver inflammation in rats with NAFLD, and it has comparable efficacy to Kezhi capsules. This therapy can be used for treating NAFLD.

AIM: To investigate the effect of Shexiang Baoxin Pill(SXBXP) on endothelial in stable angina pectoris patients and its underlying mechanisms. METHODS: Sixty-eight stable angina pectoris patients were randomly divided into two groups,the conventional group(34cases),SXBXP treatment group(34cases).The conventional group was treated with standard treatment,and SXBXP group was treated with standard treatment and SXBXP.FMD,NO,ET,TXB_2,6-Keto-PGF-1a were determined before and after three months treatment. RESULTS: FMD,NO,6-Keto-PGF-1a of SXBXP group were (9.35%?0.78%)、(77.25?6.36)?mmol/L、(93.87?(10.28))?/(ng/L) after treatment,ET、TXB_2 were(81.15?5.43) pg/mL、(43.02?4.19)?/(ng/L).There were significant improvement as compared with in SXBXP group before treatment and in conventional group after treatment(P

Objective:To explore the role of the fat mass and obesity-associated protein (FTO) in human renal tubular epithelial cells (HK-2) suffering ischemia-reperfusion injury (IRI).Methods:The in vitro IRI mo-del was established in HK-2 cells by induction with antimycin A, A23187 and 2-deoxy-D-glucose.The cells were divided into control group and ischemia-reperfusion group (I/R group). The mRNA and protein expressions of FTO, B-cell lymphoma / leukemia 2(Bcl-2)-associated X(Bax), Bcl-2 and cleaved cysteinyl aspartate specific proteinase(cleaved Caspase-3) in HK-2 cells before and after IRI were detected by real-time fluorescent quantitative PCR(qPCR) and Western blot, respectively.Cell apoptosis was measured using flow cytometry.The level ofe N 6-methy-ladenosine (m 6A) RNA was detected by colorimetry. Results:(1) The mRNA expressions of FTO (0.15±0.05 vs.1.00±0.23) and Bcl-2 (0.14±0.07 vs.1.02±0.25) in I/R group were significantly lower than those in control group; While those of Bax (3.10±0.35 vs.1.00±0.13) and cleaved Caspase-3 (4.21±0.56 vs.1.00±0.09) were significantly higher ( t=6.28, 5.84, -9.83, and -9.84, respectively, all P<0.01). (2) The protein expressions of FTO (0.69±0.14 vs.1.37±0.02) and Bcl-2 (0.50±0.12 vs.1.25±0.21) were significantly lower in I/R group than those of control group; While those of Bax (1.04±0.08 vs.0.57±0.06) and cleaved Caspase-3 (0.99±0.05 vs.0.36±0.07) were significantly higher ( t=8.10, 5.49, -8.22, and -12.09, respectively, all P<0.05). (3) Compared with the control group, the apoptosis rate of HK-2 cells in I/R group was significantly higher [(61.70±1.01)% vs.(0.16±0.10)%, t=63.80, P<0.01]. (4) Compared with the control group, the percentage of m 6A modification level in total RNA in I/R group was significantly higher [(3.13±0.21)% vs.(1.10±0.26)%, t=-10.61, P<0.01]. Conclusions:FTO-mediated RNA m 6A modification may affect renal IRI by regulating the apoptosis of HK-2 cells.

Objective:To evaluate the effects of the cassette 14C-urea breath test kit, scintillation sampling bottle (solid-state scintillation method) and liquid scintillation 14C-urea breath test kit in the diagnosis of Helicobacter pylori ( H. pylori) infection. Methods:From January 7 to October 28, 2020, 239 patients were enrolled who visited Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, the Second Affiliated Hospital of Zhejiang University School of Medicine and the First Affiliated Hospital of Nanchang University. All subjects first received 14C-urea breath test.Within >1 to <7 days after gas collection, mucosal tissues were taken under gastroscopy for gold standard test, including biopsy and rapid urease test (RUT). If both biopsy and RUT indicated H. pylori positive, the result of gold standard test was H. pylori positive, and if both were negative, the result of gold standard test was H. pylori negative. If the results of biopsy and RUT were inconsistent, they were not included in the subsequent analysis. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were analyzed. The safety of the test was evaluated by whether there were any adverse events during the test. Descriptive methods were used for statistical analysis. Results:Among the 239 subjects, 12 cases did not complete the test, 227 subjects finally completed the test. The test completion rate was 95.0% (227/239). No.008 patient was only included in the analysis of cassette 14C-urea breath test kit and scintillation sampling bottle because of lacking the result of liquid scintillation breath test. The results of gold standard test showed that among 227 patients, 87 cases were H. pylori positive, 118 cases were H. pylori negative. The results of biopsy and RUT were inconsistent in 22 cases, so they were not included in the subsequent analysis. Excluding No.008 patient, the results of gold standard test showed that 86 cases were H. pylori positive and 118 cases were negative. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cassette 14C-urea breath test kit, scintillation sampling bottle, and the liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were 91.9%, 100.0%, 96.6%, 100.0% and 94.4%, respectively; 95.4%, 97.5%, 96.6%, 96.5% and 96.6%, respectively; and 96.5%, 99.2%, 98.0%, 98.8% and 97.5%, respectively. Only one adverse event (right upper abdominal pain after eating) occurred. Combined with the patients condition, the adverse event was determined as the onset of chronic cholecystitis and it might not be related to the test medication. Conclusions:Cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit have reliable performance, good safety, and high sensitivity, specificity and accuracy in the diagnosis of H. pylori infection, which are worthy of clinical application.
