Objective Toanalyze and evaluate the value ofthe method ofmedical simulation technique combined with PBL pattern in the training before clinical practice. Methods 80 students were divided into two groups:the experimental group and the control group. The PBL method was used in the experimental group,while the control group was taught by traditional method. Results The students in experimental group had a significant higher score than those in control group. Conclu-sion It means that the method of medical simulation combined with PBL teaching is an effective leaning method and should be widely used in the training before clinical practice.

Objective:To survey the status quo of ADR occurred in our hospital. Methods:Totally 277 ADR reports were collect-ed and analyzed statistically in our hospital from January 2010 to June 2013. Results:Among the ADR cases,the ratio of male to fe-male was 1∶1. 565, and 59. 93% of ADR occurred in the people over 50 years old. Totally 240 ADR cases (86. 64%) were induced by intravenous administration and 32 ADR cases (11. 87%) were induced by oral administration. Totally 167 ADR cases were caused by antibiotics (60. 29%), among them, 54 cases wero by cephalosporins (32. 34%), 47 cases by quinolones (28. 14%) and 32 ca-ses by cephamycins (19. 16%). Totally 42 ADR cases were caused by traditional Chinese medicine injections (15. 16%), and 18 ca-ses were caused by cardiovascular system drugs (6. 5%). The main clinical manifestations were lesion of skin and its appendant organr and digestive system injury with 162 cases (58. 48%) and 62 cases (22. 38%), respectively. Conclusion: It is necessary to strengthen clinical ADR monitoring, rationally use antibiotics and emphasize the importance of safe medication of traditional Chinese medicine injections.

MicroRNA are endogenous non-coding small RNA composed of approximately 18 - 23 nucleotides, mainly participating in post-transcription gene regulation. More and more data show that miR-21 is over-expressed in many human cancer cells and it was involved in cell differentiation, proliferation and apoptosis, closely related to tumorigenesis and the development of carcinoma as oncogene. Here, we will make a review about miR-21' s target gene, biosynthesis and regulation and clinical significance in order to provide a valued data for the future study and clinical application.

Objective:To evaluate the performance of Sysmex XN-9000 automatic blood analyzer (hereinafter referred to as XN-9000) in whole blood with the low platelet (PLT). Methods:A total of 48 whole blood samples with platelet count less than 70×109/L were randomly collected from XN-9000 correlation analysis to evaluate XN-9000 the accuracy and precision of detection in low whole blood PLT and carry pollution rate, use XN-9000 and microscope count, respectively.Results: XN-9000 detection in low whole blood PLT between batch and batch of CV% 1.13% and 1.29%, respectively; XN-9000 with microscope PLT count results have high correlation, The regression equation forY=0.917X+3.217,correlation coefficientr=0.964; XN-9000 detection in low whole blood PLT carry pollution at a rate of 0.12%. Detection accuracy of PLT Bias, %(-1.25%~1.8%); Linear range(0~1206)×109/L; Clinical reportable range (0~6030)×109/L.Conclusion: The detection of XN-9000 blood analyzer is in low whole blood PLT has high precision and accuracy, carry pollution rate is extremely low, the result has the reliability, can be directly applied to clinical.

Objective To evaluate the precipitating factor,mortality,complications of myasthenia gravis crisis and risk factors of prolonged intubation.Methods Totally 82 case records of patients who had been adimitted for having 87 episodes of myasthenia crisis over a period of 15 years from January 1985 to February 2000 and their age, gender, precipitating factors, complications of intubation, and prolonged intubation factors were retrospectively reviewed. Results In 75% of myasthenic crisis patients having precipitating factors, infection was the most often served as the precipitating factors, and then the wound, fatigue, manopause and delivery came the next, 24% of precipitating factors were related to medication. Nine were identified with independent predictors of prolonged intubation. Among the 82 myasthenia crisis patients, 12 died, with a mortality of 14%.Conclusion The prevention and treatment for intubation complications may be the best way for further shortening intubation time and reducing the mortality.

OBJECTIVE:To introduce the Fair PharmaCare program of BC Canada for the reference of the reform of China's medical insurance system.METHODS:The running procedure of Fair PharmaCare program of BC Canada was introduced in detail and its characteristics were analyzed.RESULTS & CONCLUSIONS:Fair PharmaCare program covers all BC residents and protects them against economic difficulties in pharmacare.The program serves as a reference for the reform of China's medical insurance system.

Objective To investigate the effects of autologous blood transfusion on serum neopterin and IL-2 concentrations after radical gastrectomy. Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes (33 male, 27 female) aged 40-65 yrs weighing 51-70 kg undergoing radical gastrectomy for stomach cancer were randomly divided into 2 groups (n = 30 each):homologous blood transfusion group (H) and autologous blood transfusion group (A). The patients were premedicated with intramuscular diazepam 10 mg and atropine 0.5 mg. Anesthesia was induced with midazolam 0.1 mg?kg-1, fentanyl 5 ?g?kg-1, propofol 1 mg?kg-1 and vecuronium 0.12 mg? kg-1 and maintained with isoflurane inhalation (1 % -2 %) and intermittent i. v. boluses of fentanyl and vecuronium. In group H homologous blood 400 ml was infused during gastro-intestinal anastomosis. In group A 400 ml of blood was removed from radial artery after induction of anesthesia, before surgery. Blood volume was maintained by simultaneous infusion of succinylated gelatin 500 ml. The 400 ml autologous blood was infused also during gastrointestinal anastomosis. Venous blood samples were taken before operation (baseline) , at the end of operation and on the 5th postoperative day for determination of serum concentrations of neopterin and IL-2 (ELISA) Results The two groups were comparable with regard to sex (M/F ratio), age, body weight, duration of operation and total blood loss. The serum concentrations of neopterin and IL-2 were significantly decreased after operation compared to the baseline values before operation in group H (P

Asthma was considered to be a kind of chronic airway inflammatory diseases mediated by eosinophils(EOS),mast cells,T lymphocytes for a long time,and the typical pathologic features of asthma was airway EOS inflammation.The current study had found out that elevated neutrophils in airway were seen in severe asthma,and this kind of asthma had a poor response to corticosteroids.Impaired neutrophil chemotaxis and apoptosis of airway neutrophilia may be associated with persistent neutrophilic inflammation in the airways of severe asthma.A deep research into the mechanisms of neutrophilic phenotypes asthma would contribute to the new strategy of therapy.This article discusses a range of topics related to the role of neutrophilic inflammation in severe asthma in children,which were organizedas follows.

Obesity has been a world-wide growing health problem in children and adolescents,insulin resistance plays a pivotal role in the pathogenesis of obesity-associated complications,the mechanism is still unknown.There is growing evidence that obesity is associated with low-grade inflammation in youth.The onset of low-grade inflammation in obesity may be associated with the inflammatory cytokine secreted by adipose tissue,local Monocyte/Macrophage system and role of oxidative stress.The study of inflammatory cytokines in pathogenesis of obesity and insulin resistance will help to develop new treatment strategies to prevent obesity and obesity-associated complications.
