Objective To research the position transition training effect of general practitioner of northeast district of Chongqing,and find out the problems and their reasons.Methods 326 students and 150 unit leaders were chosen to make a questionnaire survey(recycled 307,150).The Kirkpatrick model was also used for data analysis from 4 levels.The result was described in percentage.Results Reaction Level:42.02％(129/307) of the trainees were not satisfied with the time arrangement of clinical medicine training; Study Level:3 courses were at high failure rate 19.54％(60/307),22.8％(70/307),17.92％(55/307); Behavior Level:81.43％(250/307)of the trainees considered the training effective; Result Level:94.00％(141/150)unit leaders considered the training had a positive impact.Conclusion The time arrangement of clinical medicine training is mostly unsatisfied and the ability of instrument using and result interpretation is weak.Most people consider the position transition training is effective.

OBJECTIVE:To observe the efficacy and safety of atorvastatin in the treatment of hypertension with unstable angi-na. METHODS:80 patients with hypertension with unstable angina were randomly divided into control group and treatment group. All patients were given anti-platelet aggregation and other conventional treatment;based on it,control group was orally treated with Amlodipine besylate tablet 5 mg,once a day+Metoprolol tartrate controlled-release tablet 25 mg,twice a day+Isosorbide dini-trate injection 10 ml by intravenous infusion,twice a day;treatment group was additionally treated with Atorvastatin calcium tablet 20 mg,orally,qd. 3 months was a treatment course,and it lasted 6 courses. Clinical efficacy,and systolic blood pressure,diastol-ic blood pressure,angina frequency and duration,changes of TC,TG,LDL,HDL levels before and after treatment and adverse reac-tions in 2 groups were observed. RESULTS:Total effective rate in treatment group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,systolic blood pressure and diastolic blood pressure in 2 groups were significantly lower or shorter than before,the difference was statistically significant(P<0.05),however,there was no signifi-cant difference between 2 groups(P>0.05);angina frequency and duration were significantly lower than before,and treatment group was lower than control group,TC,TG and LDL in treatment group were significantly lower than before and control group, HDL was higher than before and control group,the differences were statistically significant(P<0.05),there was no significant dif-ference between before and after treatment in control group(P>0.05). There was no significant difference in the adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Based on the conventional treatment, atorvastatin can effectively reduce the long-term angina frequency and duration of patients with hypertension with unstable angina,improve the ischemia myocardial and reduce the lipid levels with good safety.

Objective To investigate the value of transcatheter arterial embolization in the treatment of obstinate nosebleeding. Methods Twenty patients with obstinate nosebleed failed with conventional therapy were performed internal maxillary arterial angiography. Transcatheter arterial embolization were carried out immediately after occurance of nosebleeding. PVA or gelfoam particles were injected into the bleeding arteries under fluoroscopy control. Nasal packing was removed to see whether bleeding was stopped. Results Active bleeding occurred in all 20 patients during angiography but was stopped in all patients after embolization without severe complications. Conclusions Transcatheter arterial embolization is an useful mini-invasive method in the treatment of obstinate nosebleeding.

The principal constituents of Radix Astragali include Radix Astragali soap glucoside,Radix Astragali polysaeeharide,amino-butyric acid,calcium and trace elements (selenium,manganese,iron,zinc,copper).Radix astragali has the function of protecting heart and kidney,two-ways regulating blood sugar and the blood pressure,resisting tumor,hypoxia,senile and oxidation,and enhancing immunity.This article reviewed pharmaceutical effects of Radix Astragali and its preparation of recent studies.

Bacillus anthracis , the aetiological agent of anthrax, was the first discovered pathogenic bacterium in history Rapid progresses have been made on this field in recent years, especially; Bacillus anthracis has been sequenced successesfully early this year and published on the Internet The anthrax pathogenesis is always central to the study and there has been an enormous amount of work to elucidate it In this review, we will focus on the latest findings that concern three aspects of anthrax pathogenesis: Bacillus anthracis genome, pathogenic substances and pathogenesis mechanism

We searched the papers about laboratory education in China Scientific Journal Database(CSJD)and China Journal Full-text Database(CJFD),and carried out the bibliometric analysis on these papers in order to understand the current status and trend of laboratory education in basic medicine in China,improve the teaching quality and provide reference to the reform and construction of laboratory education in basic medicine.

Breast tumors are the most common tumors of epithelial origin. Some tumors or tumor-like lesions of the breast may display a morphology similar to mesenchymal tumors predominated by spindle cells. However, such morphology is apt to be confused with others due to lack of the characteristic histopathology. This paper reviews some spindle cell lions in the breast, in an attempt to provide theoretical evidences for the differentiation diagnosis of breast tumors and tumor-like lions.

As one of the most serious hereditary neuromuscular disease, spinal muscular atrophy (SMA) is caused by the loss or mutation of survival motor neuron 1 (SMN1) gene. It leads to a decrease in the level of SMN protein and a consequent loss of alpha neurons and progressive muscle atrophy resulting in the progressive muscle weakness, the significant disability and the shortened lifespan. Up till now, only three drugs have been approved for SMA, including the gene therapy drug onasemnogene abeparvovec. The antisense oligonucleotide drug nusinersen and and the small molecule chemical drug risdiplam were briefly introduced. Some representative samples of the small molecule chemical drugs and antisense oligonucleotide drugs targeting SMN2 in the clinical trial or preclinical research phases were also reviewed.

Objective To explore the relationship between preoperative serum pro-adrenomedullin (pro-ADM) in the patients with closed rupture of small intestine,and postoperative secondary abdominal infection,and to study the value of postoperative serum pro-ADM in assessment of severity of postoperative secondary abdominal infection of this patients.Methods Eighty-five patients with closed rupture of small intestine treated in the emergency surgery from June 2014 to May 2015 were selected.According to the presence of postoperative abdominal infection or not,these patients were divided into infection group and non-infection group.The infection group was further divided into SIRS,sepsis,severe sepsis,septic shock subgroups as per the severity of infection.The levels of serum pro-ADM,interleukin-6 (IL-6),C-reactive protein (CRP) were determined and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was calculated at admission and the first day、the second day and the third day after operation.Comparisons of these biomarkers were carried out to find out the factors associated with postoperative abdominal infection.In addition,ROC curve was used to verify the factors for predicting the abdominal infection of these patients after operation.The relationship between serum levels of pro-ADM and APACHE Ⅱ score after operation was analyzed.The severity of abdominal infection after operation was assessed with laboratory findings.Results Compared with non-infection group,preoperative and postoperative serum pro-ADM (P =0.03,P ＜ 0.01),IL-6 (P =0.02,P ＜0.01) levels and APACHE Ⅱ scores (P ＜ 0.01,P ＜ 0.01) were significantly higher in infection group (P ＜ 0.05).In the infection groups,the postoperative levels of serum pro-ADM and APACHE Ⅱ scores were increased with the severity of infection increased (r =0.924),and the difference between the groups was statistically significant (P ＜ 0.05),but there were no significant differences in IL-6 and CRP levels between two groups.Conclusion (1) The serum levels of pro-ADM before operation has value in predicting the genesis of abdominal infection in these patients after operation.(2) The serum levels of pro-ADM after operation has value in severity assessment of abdominal infection in these patients after operation.
