Task-based language teaching is one of the most widely adopted teaching approaches.When applying task-based language teaching,college English teachers should stick to the people-oriented principle,pay attention to the practical need of their students and reasonably design different tasks so as to achieve an ideal construction of task-based language teaching model.

By comparing the correlated evaluation index between Researches in Medical Education and Chinaese Journal of Medical Education,the author analyzed their differnces to promote one another and raise the quality of running both journals.

Using the information metrology's correlation theories and literature measurement method, this article makes statistics of the PBL related research papers in our country's medical education published in 1979-2010 and analyzes this domain's distribution of time, article quantity, authors'units and key word term frequency. We propose that PBL research should be further standardized in the concept aspect and the research technique as well as the discipline involved should be further multiplied in our country.

OBJECTIVE:To observe the effect of acyclovir on neurological function and cytokines of children with viral menin-gitis. METHODS:Totally 70 children with viral meningitis were randomly divided into control group and observation group. All children were given routine treatment,including defervescence,reducing intracranial pressure and regulating water and electrolyte balance,etc. Based on it,the control group was treated by Ribavirin glucose injection 15 mg/kg,iv,bid;observation group was treated by Acyclovir glucose injection 5 mg/kg,iv,tid. The course for both was 7 d. The clinical data was compared,including the vascular endothelial growth factor (VEGF),matrix metalloproteinase-9 (MMP-9) in cerebrospinal fluid (CSF) and serum,insu-lin-like growth factor-Ⅱ(IGF-Ⅱ) and insulin like growth factor binding protein-3(IGFBP-3) in CSF before and after treatment and the incidence of adverse reactions. There were no obvious adverse reactions during the treatment. RESULTS:After treatment, the VEGF and MMP-9 in serum and the VEGF,MMP-9,IGF-Ⅱ and IGFBP-3 in CSF in 2 groups were significantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There was no adverse reactions in 2 groups during the treatment. CONCLUSIONS:Compared with ribavirin,acyclovir can more obviously improve the neurological function and cytokines of children with viral meningitis,with similar safety.

Objective To study the effects of recombinant human erythropoietin(r-HuEPO) on RBC immunity in chronic renal failure(CRF) patients.Methods Forty-five CRF patients were divided into two groups : 20 patients without r-HuEPO(control group) and 25 patients with r-HuEPO more than one month(experimental group).The RBC-C_(3b)RR and RBC-ICRR in two groups were counted under microscope and the correlations between HB or CRE and RBC-C_(3b)RR were calculated.Results The concentrationd of Hb,RBC-C_(3b)RR in experimental group were much higher than those in control group(P

0.05).The level of serum EGF in the tumor group(0.426?0.084 ng/ml～0.456?0.095 ng/ml)was significantly higher than that in the control group(0.243?0.086 ng/ml,P

Institute for International Medical Education(IIME)established the Global Minimum Essential Requirements(GMER)in Medical Education in 2001.This article is to unscramble the connotation of GMER,reveal the transformation of the medical model and gives some thoughts on how to let GMER become the standard and carried out in our country so as to benefit the current reform of medical education.

Objective To investigate serum procalcitonin(PCT)and C-reactive protein(CRP)and clinical significance of changes in children with pneumonia.Methods 123 cases of childhood pneumonia included 48 cases of bacterial infection,mycoplasma infection in 36 cases,39 cases with viral infections,40 cases of physical healthy children were selected as the control group.They were measured in serum PCT and CRP content of the correlation between test results and analysis of clinical final diagnosis.Results The level of PCT in Bacterial pneumonia group, Mycoplasma pneumonia group and viral pneumonia group were (5.80 ±1.92)μg/L,(0.45 ±0.15 )μg/L and (0.32 ±0.17)μg/L,respectively,significantly higher than control group(0.19 ±0.10)μg/L(t =5.37,3.41,1.23, all P <0.05);the level of CRP in Bacterial pneumonia group,mycoplasma pneumonia group and viral pneumonia group were(45.34 ±13.35 )mg/L,(28.63 ±11.37)mg/L and (8.19 ±2.07)mg/L,respectively,significantly higher than control group(3.85 ±1.31)mg/L(t =5.37,3.41,1.23,all P <0.05);serum PCT sensitivity to detect pneumonia children,specificity and the positive predictive were 93.56%,82.35% and 69.25%,respectively,higher than serum CRP diagnosis of pneumonia sensitivity,specificity and positive predictive(χ2 =4.41,5.83 and 7.62, respectively,all P <0.05).Conclusion Serum PCT and CRP measurement can be used as an auxiliary to identify indicators of childhood pneumonia,the diagnosis of pneumonia in children has important clinical significance.

Objective To study the therapeutic methods of cholecystic duct stones. Methods A retrospective analysis of the clinical data of 158 cases of cholecystic duct stones treated in the recent 6 years was made. Results 97 of the 158 cases of cholecystic duct stones were removed by open surgical operation and 61 cases by laparoscopic cholecystectomy(LC).In 49 of the 61 cases treated with LC,the cholecystic duct stones were removed together with removal of the gallbladder, and 12 by duodenoscopy after LC. Conclusions One should strive to extract the cholecystic duct stones while removing the gallbladder. If the stones or stone fragments escape into the common bile duct, they could be removed through a choledochotomy at the time of the open operation ,or by postoparative duodenoscopy in cases undergoing LC. The latter method of treatment is associated with minor trauma, quick recovery and definite therapeutic results.

Objective:To study the curative efficacy of functional training focusing on muscle group around shoulder for subacromial impingement syndrome.Method:Forty five patients with subacromial impingement syndrome (SIS) were randomly grouped into three groups (fifteen patients for each group).Patients in Group Ⅰ were trained only on muscles around scapula.Patients in Group Ⅱ were treated on rotator cuff muscles.While patients in Group Ⅲ were treated on both.The training goes every 2 days and last for 4 weeks.The indexes for evaluating curative efficacy included:the Neer-test,the Hawkins-test and the Peen Shoulder Score.These indexes were measured immediately and three months after the four week treatment.Result:After treatment of the functional training focusing on muscle group around shoulder,Neer-tests and Hawkins-tests of all of patients were changed from positive to negative,the degree of pain compared with pain before the treatment declined apparently(P＜0.01),at the same time,the degree of satisfaction and the function went up remarkablely(P＜0.01).Compared with group Ⅰ and group Ⅱ,it dropped the most notably on the degree of pain in the group Ⅲ(P＜0.01),however,the degree of satisfaction and the function rose most apparently (P＜0.01) Conclusion:The curative efficacy of functional training focusing on muscle group around shoulder for sub-acromial impingement syndrome was effective apparently.But the efficacy of treated focusing on both muscles around scapula and rotator cuff was the most remarkably.
