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.

Objective To investigate the maternal attitude and demands for Institute of Postpartum Care in order to provide targeted services.Methods 285 women were a investigated about maternal attitude and demands towards Institute of Postpartum Care with self-designed questionnaire.Results 97.9% (279/285) women thought sitting the month (puerperal period) was very important,50.2% (143/285)women were interested in Institute of Postpartum Care.They thought the main three advantages were energy saving,medical expertise and technology and avoidance of family conflicts;The three major issues were high price,lack of monitoring mechanism and unfamiliar environment and less family company;33 items of services demands over four points accounted for 78.6%,the three modules with highest scores were cleaning services scored 4.64±0.47,newborn services scored 4.45±0.41,consultation service scored 4.41:±0.53.Conclusions Professional postnatal care services have been a trend and social need,and a large proportion of women have great interest and demand on Institute of Postpartum Care which should make full use of its concentrate resources,and provide specific services according to maternal demands for services.It is urgent to build unified service standards and evaluation indicators to improve service quality.

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.

Objective A scientific evaluation of hospital culture with the Dimension organizational culture model, in view of features of China's general public hospitals.Methods Based on Denison model, according to the characteristics of the public general hospitals in China, the authors developed a tool for organizational culture assessment (TOCA) by using the survey data from 87 hospitals in three provinces from the East, Central, and West areas in China.Results This tool, an evaluation scale, comprises the four cultural characteristics of direction, consistency, participation, and adaptability, as well as 13 cultural dimensions of social responsibility and competitive consciousness. The tool is tested as having good internal reliability and validity.Conclusion The TOCA provides hospital administrators with a tool for hospital culture evaluation, diagnosis and improvement.

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 study the expressions of erythmpoietin(EPO)and its receptors(EPOR)in the injured brain tissue ofthe rats with traumatic brain injury(TBI).Methods A total of78 SD rats were randomly divided into three groups including control group(six rats),sham group(36rats) and fluid percussion injury group(36 rats).The rats were sacrificed at 6,24 hours,3,5,7 and 14days after TBI in the sham group and the fluid percussion injury group(six rats at each time point).Then,the injured brain tissues were removed for observation of the mRNA and protein expressions of EPO and EPOR by meaDiB of real-time PCR and Western blot. Results The expression of EPO was increased at 24 hours and reached the peak at day 3 after TBI.The hish expression level of EPO could maintain for two days or so.began to decrease at day 7 and recovered to normal at day 14 after Till.While the expression of EPOR reached the peak at 24 hours after TBI and maintained hish level at day14. Conclusions The expressions of EPO and EPOR show increase within 24 hours after TBI.In fact,the expressions of both factors are not in consistency,with more transient expression of EPO.

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.
