Objective To evaluate the effects of anisodamine on apoptosis in cardiomyocytes and inflammatory response in overtrained rats. Methods Twenty-four male Wistar rats, weighing 200-220 g, were randomly divided into 3 groups ( n = 8 each) : control group (group C) , overtraining group (group O) , anisodamine group (group A) . The model of overtraining-induced acute heart injury was established by exhausting swimming. Anisodamine 10 mg/kg was given intraperitoneally 20 min before overtraining in group A. Blood samples were taken at 6 h after overtraining for measurement of serum CK-MB activity. The rats were then sacrificed and myocardial tissues taken for determination of TNF-α content and NF-κB activity (by immunohistochemistry) . The apoptosis rate was detected by flow cytometry. Results The CK-MB activity, apoptosis rate, TNF-α content and NF-κB activity were significantly higher at 6 h after overtraining in groups O and A than in group C, while lower at 6 h after overtraining in group A than in group O ( P < 0.05) . Conclusion Anisodamine can inhibit apoptosis in cardiomyocytes by reducing inflammatory response in overtrained rats.

The presence of insufficient bone volume affects the implant healing and success. The aim of this study was to evaluate osteogenic capacity of dental pulp stem cells (DPSCs) on micro-arc oxidation (MAO) titanium surface. DPSCs were challenged at MAO and smooth titanium surface separately for different durations, and the bone marrow mesenchymal stem cells (BMSCs) served as the positive controls. The osteogenic capacity of DPSCs on MAO titanium surface was assessed by using scanning electron microscopy, energy dispersive spectroscopy, biochemical tests and real-time quantitative PCR. Data showed that DPSCs differentiated into osteoblasts and expressed bone morphogenetic genes on MAO titanium surface. The results of this study revealed that DPSCs had good potential to generate mineralized tissue on MAO titanium plates. The differential potential of DPSCs may be regulated by MAO titanium surface. The osteogenesis potential of DPSCs on the MAO titanium was similar with BMSCs.

Emerging data indicated that HCV subverts the antiviral activity of interferon (IF); however,whether HCV core protein contributes to the process remains controversial. In the present study, we examined the effect of HCV core protein on interferon-induced antiviral gene expression and whether the effect is involved in the activation and negative regulation of the Jak/STAT signaling pathway. Our results showed that, following treatment with IFN-α, the transcription of PKR, MxA and 2'-5'OAS were down-regulated in HepG2 cells expressing the core protein. In the presence of HCV core protein,ISRE-dependent luciferase activity also decreased. Further study indicated that the core protein could inhibit the tyrosine phosphorylation of STAT1, whereas the level of STAT1 expression was unchanged.Accordingly, SOCS3, the negative regulator of the Jak/STAT pathway, was induced by HCV core protein. These results suggests that HCV core protein may interfere with the expression of some interferon-induced antiviral genes by inhibiting STAT1 phosphorylation and induction of SOCS3.

Objective To analyze the influencing factors of having clinical meaningful recanalization (CMR)after revascularization therapy in acute phase of ischemic stroke. Methods A total of 267 consecutive patients with ischemic stroke admitted to the Department of Neurology,Xuanwu Hospital, Capital Medical University and received intravenous thrombolysis or endovascular intervention in acute stage from March 2011 and March 2015 were enrolled retrospectively. CMR was used as a primary endpoint event. They were divided into either a CMR group (n = 92)or a non-CMR group (n = 175)according to whether they had CMR. The baseline data of the patients in both groups were compared by using the Rank sum test and Pearson Chi-Square test. A multivariate logistic regression model was established to analyze the independent influencing factor of CMR. Results The median (interquartile range)age of 267 patents was 60 (51 -69)years,and 69 of them were females (25. 8%);the median (interquartile range)time from onset to treatment was 250 (195 -305)min,and the median (interquartile range)NIHSS score was 10 (6 -15). The baseline NIHSS score,body mass index,blood glucose level,and proportion of diabetes of the CMR group were significantly lower than those of the non-CMR group (all P≤0. 05). The results of multivariate logistic regression analysis showed that the baseline NIHSS (OR,0. 93,95% CI 0. 88 -0. 98;P = 0. 01),intravenous thrombolysis (with respect to endovascular intervention)(OR,0. 35, 95% CI 0. 17 -0. 73;P = 0. 01),and baseline blood glucose (OR,0. 87;95% CI 0. 77 -0. 98;P =0. 02)were the independent negative predictors of CMR. Conclusion The baseline NIHSS,intravenous thrombolysis (with respect to endovascular intervention),and high blood glucose are the negative influencing factors for achieving CMR in the acute phase of ischemic stroke,suggesting blood sugar intervention and endovascular intervention in acute phase may contribute to the improvement of clinical prognosis.

Objective: To investigate the value of positron emission tomography/computerized tomography(PET/CT) with fluorine-18-labeled fluorodeoxyglucose(18FDG) for gastric carcinoma.Methods: Thirty-two patients(25 males,7 females,aged 31-82 years) suspected of gastric carcinoma underwent whole-body PET/CT after taking in 600 ml of water to distend the gastral cavity.The maximal standard uptake value(SUVmax) of the region of interest(ROI) in PET and the maximum width of the gastric wall in CT were analyzed.Pathological specimens were obtained from all the patients during surgery or gastroscopy.Results: 18FDG PET/CT found gastric carcinoma in 24 of the patients.The rates of positive and negative prediction and the accuracy of PET/CT in the diagnosis of the disease were 92.3%,100% and 93.8%.SUVmax was positively correlated with the maximum width of the gastric wall,but they exhibited no statistically significant differences between the patients with involved lymph nodes and those without.Based on the PET/CT findings,the 24 gastric carcinoma patients were clinically classified as follows: 9 in stage Ⅰ,1 in stage Ⅰ-Ⅱ,3 in stage Ⅱ,1 in stage Ⅲ and 10 in stage Ⅳ.Conclusion: 18FDG PET/CT is highly valuable for gastric carcinoma in its diagnosis,the evaluation of its biological behavior and determination of its treatment strategies.
