OBJECTIVE:To study the mechanism that apoptosis of NB4 cells were induced by artesunate. METHODS: The apoptosis of NB4 cell induced by artesunate was determined by Annexin V-FITC FCM analysis and cytomorphology and the activity of Caspase-3 was determined by ELISA assay. RESULTS: Artesunate could induce apoptosis of NB4 cell with the activity of Caspase-3 increasing. CONCLUSIONS: The apoptosis of NB4 cell induced by artesunate is achieved by activating Caspase-3.

The contents, methods and commons of social information service in Markerere University Library were analyzed according to the social information service in domestic academic libraries and the enlightenments on extending social information service in domestic academic libraries were elaborated, such as active participating in study of social problems and attaching importance to librarians training .

The deficiencies in reading popularization at present were analyzed, the concepts of liberal education and liberal platform were described, and the successful experiences in liberal platform-based reading popularization in academic libraries were summarized, such as experiencing human library by stressing on communication between users, achieving the reading and education effect by applying the liberal concept, selecting reading materials based on the needs of teachers and students, and establishing special reading popularization team.

Objective Compared with surgical operation,to investigate the clinical efficacy and advantages of interventional treatment in blunt liver traum.Methods 32 patients from July 2010 to October 2012,who were diagnosed as blunt liver trauma,received super selective hepatic artery embolization in Chinese People's Liberation Army in 98th Hospital.Another 27 ones received operation at the same time in Peolies's Liberation Army 98th (AAST grade Ⅱ to Ⅳ).Retrospective analysis of related cases was presented.The results were analyzed by t test.Results All of 32 patients that received super selective hepatic artery embolization were stanched bleeding successfully.All patients were followed up for 3 to 18 months,the mean follow-up time was 10 months,with no severe complications occurred or no lost cases.Conclusions Compared with surgical operation,interventional treatment had advantage that included eliable hemostasis,less operation time,minimally invasive and less hospitalization time.Interventional treatment had good effects on blunt liver trauma which were AAST grade Ⅱ to Ⅲ.

The need for special medical services are described and analyzed from the connotation of the characteristics of several types and models,in the hope of providing reference for the study of special need of medical services.

Objective To compare the clinical efficacy between Jian Huan Tong Tiao needling (acupuncture at both healthy and affected sides) and acupuncture at the affected side alone in treating peripheral facial paralysis (FP) in acute stage, and to provide evidences for the acupuncture treatment of peripheral FP in acute stage.Method Fifty patients were randomized into a Jian Huan Tong Tiao needling group (25 cases) and an affected side needling group (25 cases). By selecting the same acupoints, the Jian Huan Tong Tiao needling group received acupuncture at both sides, while the affected side needling group received acupuncture only at the affected side, once every other day, successively for 4 weeks. House-Brackmann (H-B) facial nerve grading system was used to score the facial nerve function before and after the treatment, and the therapeutic efficacies were compared between the two groups.Result The facial nerve function was improved in both groups, while the therapeutic efficacy was superior in the Jian Huan Tong Tiao needling group to that in the affected side needling group (P<0.05); after 2-week treatment, the H-B score was higher in the Jian Huan Tong Tiao needling group than in the affected side needling group (P<0.05); of the recovered cases, the relapse rate was lower in theJian Huan Tong Tiao needling group than in the affected side needling group (P<0.05). Conclusion Jian Huan Tong Tiao needling can boost the recovery of the facial nerve function in peripheral FP, reduce the relapse rate, and produce a higher therapeutic efficacy than needling the affected side alone.

Objective To investigate the status quo of the medical staff in 6 village clinics in Fengjie County, and to put forward countermeasures and suggestions for improving the quality and overall quality of medical personnel in village clinics. Methods The research literature and questionnaires were used to investigate the basic situation of the village doctors, the role of the village doctors in the residents' health care, and the needs and satisfaction of the residents in the village clinics. The data were analyzed by SPSS 19.0, and the samples were analyzed by descriptive statistics. Results The average age of the medi-cal staff in village clinics was (46.74±10.17) years old, and there was no medical staff under 30 years of age. The medical staff of the village health clinics had an irrational age structure, and the educational back-ground was generally low; the medical staff generally thought that their income was not high. They hope to participate in more training in medical technology; residents generally believe that the doctors' ability to diagnose and treat the disease needs to be improved. Conclusion It is necessary to strengthen the leading role of the government and bring into play the positive work of the medical staff in the village health clinic. It is also necessary to strengthen the training of talents, lay a solid foundation for development, take the demand as the guide to change the service concept and model, to improve the relevant mechanisms to create good surroundings for the development of medical staff in village clinics.

ObjectiveTo explore the prognosis and relationship between soluble differentiation antigen of cluster designation 14 (sCD14) and the injury severity score (ISS) of casualties with multiple injuries.Methods A total of 86 casualties with multiple injuries were enrolled from October 2009 to March 2010,and the severity of trauma of casualties were assessed in ISS score within the first 24 hours after accident,and the patients were divided into survival and non-survival groups as per the outcomes in 28 days after accident. Another 20 healthy subjects served as control group. In multiple injuries group,sCD14 concentrations were detected and APACHE Ⅱ scores were calculated on the 1st,3rd,5th and 7th days after accident.The related coefficient between sCD14 and ISS was calculated and then the values of sCD14 in predicting prognosis were analyzed by ROC curve. ResultsCompared with control group, sCD14 concentrations were obviously higher in casualties of multiple injuries group at all observation intervals ( P ＜0.01). Compared with survival group, casualties of non-survival group had more higher sCD14 concentrations and APACHE Ⅱ scores ( P ＜ 0.05 ).The sCD14 concentration was correlated with ISS and the related coefficient was 0.469 ( P ＜ 0.01 ). ROC curve analysis suggested sCD14 had values in predicting prognosis of casualties with multiple injuries and area under ROC curve was 0.820.Conclusions The concentration of sCD14 is correlated with ISS and can be used for predicting the prognosis of casualties with multiple injuries.

At present, there are 8 sources of neural stem calls (NSCs), such as the early embryo, umbilical cord blood, brain tissue of adults and bone marrow, which are used for experiments. Four methods are also provided to isolate NSCs, for example, the serial passage and the gene transduction. Most of the hotspots at home and abroad are on the modulation of NSC transplantation in vivo, to make it proliferate and differentiate in hand. Most findings are achieved through experiments on rodents, no matter in vitro or vivo, which indicate that the proliferation and differentiation of NSCs can be affected by a variety of biological factors and drugs. Even more, the effects are multiple according to the factors and drugs of different kinds and the same kind of different concentrations, even the same factor would have different roles in different process of the culture of NSCs. The survival of NSCs during transplantation can also be affected by local microenvironment. Neither the NSC endogenous nor exogenous treatment is efficient. Furthermore, the body also rejects the exogenous NSCs. Taken together, it is tough for us to conclude that a factor does have some effects on the NSCs. Moreover, there are still a series of key problems unveiled clinically, such as how to perfect transplantation and whether to choose exogenous or endogenous NSCa for transplantation.
