OBJECTIVE: To study the anti-inflammatory and analgesic effects of vitacoxib. METHODS: The in vitro COX-1 and COX-2 inhibitory activities of vitacoxib were tested in human whole blood assay as well as canine whole blood assay. The anti-inflammatory and analgesic effects of vitacoxib were evaluated in several in vivo models including croton oil induced mouse ear endema, carrageenan-induced rat paw swelling and mouse acetic acid writhing model. RESULTS: In vitro assay, vitacoxib has potent inhibitory COX-2 activity and selectivity for COX-2 over COX-1. In vivo anti-inflammatory experiments, vitacoxib has significant inhibitory activities both in croton oil-induced mouse ear oedema model test(P < 0.01) and the carrageenan-induced rat paw swelling test(P < 0.05). In vivo analgesic effect experiments, vitacoxib has significant inhibitory activity on acetic acid-induced writhing pain in mice (P < 0.05). CONCLUSION: Vitacoxib, a selective COX-2 inhibitor, demonstrates excellent anti-inflammatory activity in both in vitro and in vivo models tested.

To investigate the induction of apoptosis of mouse colonic adenocarcinoma CT26 cells by recombinant Clostridium difficile toxin B (rTcdB), CT26 cells were exposed to different concentrations of rTcd B. Inhibition of cell proliferation was measured by MTT assay. The activation of Caspase 3 was measured by colorimetric method. Cell morphological analysis and flow cytometry were performed to confirm cell apoptosis. rTcd B inhibited the proliferation of CT26 cells in a timeand dose-dependent manner. Caspase 3 activity in CT26 cells was elevated remarkably after rTcd B exposure for 6 h, 12 h, 18 h or 24 h, as compared with the control group. Morphological changes were observed by fluorescence microscopy. The exposure of rTcd B to CT26 cells induced a timeand dose-dependent apoptotic cell death as determined by flow cytometry analysis. The results showed that recombinant Clostridium difficile toxin B induced apoptosis of CT26 cells.

Objective To observe the effect of Ningxia aqueous extracts of fruitless lycium sprout (AEFLS) on cardiomyo cyte antioxidation and apoptosis-related protein expression in aging mice.Methods The natural aging C57BL/6J mice with 13 months old were randomly divided into aged control group,AEFLS low dose group (AEFLS1),AEFLS middle dose group (AEFLS2)and AEFLS high dose group(AEFLS3).The AEFLS1,AEFLS2 and AEFLS3 groups were respectively given with 5,10,20 mg/kg AEFLS gavage,while the aged control group was given with the normal saline gavage,for continuous8 weeks.The xan thine oxidase assay and thiobarbituric acid method were used for the determination of SOD and MDA in heart tissues.Western-blot and immunohistochemical method were used to detect the expressions of Bcl-2,Bax and Capase-3 in heart tissue.Results Compared with the aged control group,the MDA level in the AEFLS2 and AEFLS3 groups was decreased,while the SOD activity was increased,the difference was statistically significant (P＜0.01).The Western-blot result showed that compared with the aged control group,the optical density value of Bcl-2 in the AEFLS2 and AEFLS3 groups was increased,but the optical density values of Bax and Capase-3 were decreased (P＜0.01);the immunohistochemical results showed that compared with the aged control group,the immunopositive(IP) expressions of Bcl-2 protein in heart tissues in the AEFLS2 and AEFLS3 groups were increased (P＜0.01),while the IP expressions of Bax and Capase-3 were decreased (P＜0.01).Conclusion Middle and high doses of AEFLS can increase the antioxidative ability of myocardial tissue,up-regulates the Bcl-2 expression,down-regulates the Bax and Capase-3 expressions and plays anti-cardiomyocyte apoptotic role.

Objective The study aimed to evaluate the effects of web-problem-based learning (WPBL) in the application of Fundamental Nursing.Methods The sample was purposively selected.172 students in School of Nursing in Tianjin were recruited as the control group (n=83) and the intervention group (n=89).Traditional teaching method and WPBL was implemented in the control group and the intervention group,respectively.The teaching effectiveness of the two groups was measured by the examination and learning initiative evaluation scale and the teaching effect evaluation questionnaire,and the teaching satisfaction questionnaire was implemented among the intervention group.SPSS 18.0 was used and t test was performed to analyze the comparison between groups.Results In the theoretical examination,the scores of comprehensive analysis of the nursing students in the intervention group were better than those in the control group,and the difference was statistically significant (P＜0.05).In the evaluation of active learning after school,the scores of control learning in the intervention group were higher than those in the control group,and the difference was statistically significant ([14.78 ± 2.16),vs.(13.58 ± 2.16),t=-3.58,P=0.000].83 effective questionnaires of intervention group nursing students' teaching satisfaction were recovered.73 of them (88％) thought that WPBL could improve the students' ability of independent learning,71 students (85.5％) found that WPBL could enhance the ability of information processing,73 students (88％) thought they could communicate well with their classmates in WPBL and cooperate well to complete the task.Conclusion WPBL which is on the basis of PBL and make full use of the network,could promote the ability of autonomous learning,information processing and communication with classmates and good cooperation,but in the application process,it needs teachers to organize reasonably,perfect the supervision mechanism,and reduce taking up students' spare time.

Objective To explore the relationship between the obstetric factors defined by Robson Ten-Group Classification System (RTGCS) and cesarean section rate (CSR),and to evaluate the validity of predictive models established based on the RTGCS for cesarean section.Methods Clinical data of 41 295 cases delivered in Shanghai First Maternity and Infant Hospital from January 1,2012 to September 30,2014 were retrospectively collected.CSR of different groups categorized by the RTGCS was analyzed by descriptive epidemiological methods by three models.Model 1 was obstetrics factors (parity,history of cesarean section,number of fetus,mode of labor,fetal presentation and gestational age);model 2 was obstetrics factors (model 1) + demographic characteristics and severity (maternal age and with/without treatment in intensive care unit);model 3 was defined as model 2+ complications (placenta previa,placental abruption,chronic or gestational hypertension,preeclampsia,renal disease,or human immunodeficiency virus infection).The relationship between obstetrics factors classified by the RTGCS and CSR was analyzed by the logistic regression model (the potential confounders were controlled).The validity of predictive models was evaluated by analyzing the area under the receiver operative characteristic (ROC) curve.Results (1) There were statistical differences in total CSR and CSR before labor among those cases respectively grouped by age,medical insurance,parity,signal/multiple pregnancy,fetal presentation and gestational age (all P＜0.05).(2) The recruited cases were categorized into ten groups according to the RTGCS and among them,the second group (single,cephalic presentation,nulliparous,≥ 37 gestational weeks,induced labor or cesarean section before labor) accounted for most of the cesarean section cases (61.2％,11 217/18 322),followed by the fourth group (single,cephalic presentation,multiparous,no previous cesarean section,≥ 37 gestational weeks,induced labor or cesarean section before labor),which were 11.2％ (2 061/18 322).(3) Obstetrical parameters,including parity,number of fetus,mode of delivery,history of cesarean section,fetal presentation and gestational weeks at delivery were related to CSR,even after adjustment for maternal age and medical insurance,or obstetrical complications,or both above factors (all P＜0.05).(4) Areas under the ROC curves and the 95％ confidence intervals of model 1,2 and 3 were 0.867 (0.863-0.870),0.875 (0.872-0.878) and 0.881 (0.878-0.885),respectively (all P＜0.01).Conclusion Related variables of RTGCS highly correlate with CSR and could be used as promising indicators for prediction of cesarean section.The RTGCS is of great application value to those research subjects.
