Resident doctor is the beginning period of a doctor career. Resident standardization training is the basement period for the clinical ability training and is the important part for medical students after graduation education. Vascular ultrasonography belongs to ultrasound medicine and has its own discipline characteristics. The diagnosis accuracy of vascular ultrasonography largely depends on the accumulation of basic knowledge of multiple clinical sciences , standardization of operation techniques and especially the accurate application of hemodynamic theory. According to the discipline characteristics of vascular ultrasonography, we train the residents from the following five aspects: basic theory knowledge, operation techniques, clinic thinking ability, sciences research ability, communica-tion and team work ability. On the basis of practice, we explore the establishment of standardized training mode for medical professionals of vascular ultrasnography in China, training practical, innova-tive and independent talents, to provide reference for improving the professional level of vascular ultra-sound in our country.

Objective To investigate the value of BISAP scoring system in predicting the severity of acute pancreatitis.Methods Medline,EMBASE,Science Direct,Springer link,CBM,Cnki,Wan fang and VIP database were retrieved by computer between January 2000 and March 2013,and articles of BISAP score system in predicting the acute pancreatitis were collected according to strict inclusion criteria.Quality assessment was made by QUADAS scale.Meta-Disc1.4 software was used to analyze the heterogeneity of included articles and perform quantitative synthesis,as well as calculate the pooled sensitivity and specificity,positive likelihood ratio,negative likelihood ratio,and draw the ROC curve,and the results were presented with 95％ CI.Results A total of 11 articles were included,and there were 7 Chinese articles and 4 English articles.According to QUADAS scale,there were 4 articles of A grade,5 articles of B grade,2 articles of C grade.There were 6 studies using 2 as BISAP cut-off value,and 9 articles using 3 as cut-off value,while 4 studies using 2 cut-off values.Pooled analysis showed diagnostic odds ratio of 8.03 (95 ％ CI 5.66-11.38) when cut-off value was 2,and diagnostic odds ratio of 7.49 (95％ CI 5.35-10.49) when cut-off value was 3.There were moderate heterogeneity in both groups (I2 =63.3 ％,P =0.018; I2 =56.1％,P =0.019).When BISAP cut-off value was 2,the pooled analysis of sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and area under curve (AUC) were 59％ (95％ CI56％-63％),82％ (95％ CI 80％-83％),3.50 (95％ CI2.96-4.14),0.45 (95％ CI0.36-0.56) and0.82; and when BISAP cut-off value was 3,the corresponding values were 44％ (95％ CI41％-47％),90％ (95％ CI 89％-91％),4.59 (95％ CI 3.31-6.37),0.64 (95％ CI 0.61-0.68) and 0.64.The former had a high sensitivity,low specificity and large AUC,while the latter had a low sensitivity,high specificity and small AUC.Conclusions The best cut-off value of BISAP in predicting SAP is 2.When cut-off value is 2,the misdiagnosis rate is low,and the false positive rate is in the acceptable range,which is suitable for clinical application.

Objective To explore the efficacy, safety,time of drug taking effect and therapeutic dosage of sertraline in treatment of child emotional disorder. Method One hundred and forty-seven patientswith child emotional disorder were treated by sertraline and the efficacy rate, therapeutic dosage, the time of drug taking effect and adverse reaction was analyzed retrospectively. Results One hundred and thirty-seven patients were regular visited under supervision of a physician. Two months after treatment, the efficacy rate was 80.3%(110/137) and the rate of adverse reaction was 5.8%(8/137). The therapeutic dosage of sertraline was (47.9 + 19.0) mg/d. The time of drug taking effect was (20.4±13.2) d. The therapeutic dosage of sertraline in obsessive-compulsive disorder [(58.7±26.2) mg/d] was significantly higher than that in depression[(43.6±14.0) mg/d],anxiety disorder[(44.4±10.6) mg/d] and phobia[(43.5±15.5) mg/d](P < 0.01 ). The time of drug taking effect in depression[( 14.0±6.1 ) d] was significantly shorter than that in obsessive-compulsive disorder[(26.6±16.3) d,anxiety disorder [(22.3±13.9) d] and phobia [(21.4±12.8) d] (P <0.01). Conclusions Sertraline is an efficient and safe medicine in treatment of child emotional disorder. Its adverse reaction is slight and most patients can tolerate. But it takes higher therapeutic dosage in obsessive-compulsive disorder and the time of drug taking effect is earlier in depression than in other disorder.

Objectives:To observe the effect of rhGH in the treatment of chronic wasting diseases. Methods:Twenty two cases of chronic wasting diseases needing nutrition support were chosen,including 10 cases of COPD,12 cases of cerebral infarction or cerebral hemorrhage with decubital ulcer in recovery phase.They were in the age of 60～75,in combination with morderate malnutrition.These patients were divided into control group and experimental group.In the experimental group,rhGH(4.5 U/d) was given hypodermically for 10 days.Serum albumin,prealbumin,transferin,24 h urea nitrogen in urine,the surface area of decubital ulcer and mental state were monitored before and after the treatment. Results:In the experimental group,many nutritional indices were increased markedly,24 h urea nitrogen excretion was decreased,the healing of decubitus was faster and mental state was better when compared with control group. Conclusions:The rhGH plays an important role in improving the nutritional status and mental state in patients with chronic wasting diseases. On the base of supplying enough nutrients, rhGH can promote anabolism,reduce the excretion of urea nitrogen in urine, accelerate the healing of decubital ulcer and improve the prognosis.

Objective To establish the prevalence of renal involvement in a large group of patients with type 2 diabetes and evaluate several risk factors of early stages and advanced stages of albuminuria. Methods Five hundred and sixty-six patients(265 males, mean age:57.8?13.3 years, diabetes duration 8.35?6.4 years;301 females, mean age:60.0?12.4 years, diabetes duration 9.9?7.3 years) from the endocrinology unit of Beijing Tongren hospital were included in this study. Urinary albumin excretion rate(UAER),age ,diabetes duration, arterial blood pressure, body mass index(BMI),waist to hip ratio(WHR),fasting blood glucose(FBG),HbA1c,lipid profile were evaluated. Results The prevalence of microalbuminuria, macroalbuminuria was 24.6% and 16.8% respectively. On logistic regression analysis, using the presence or absence of microalbuminuria as dependent variable, arterial blood pressure and, fasting blood glucose were included in the model in both males and females. When analyzing patients with microalbuminuria vs those with macroalbuminuria, in females, arterial blood pressure and triglycerides were included in the model. In males, only blood pressure was included in the mole. Conclusions High fasting blood glucose and arterial blood pressure were independent risk factors of microalbuminuria in type 2 diabetic patients .High arterial blood pressure and disorder in lipid profile were independently associated with macroalbuminuria.
