Objective To investigate the relationship between BRCA1 protein expression in lung cancer tissues and the effect of gemcitabine and Cisplatin based chemotherapy.Methods 80 cases of squamous cell carcinoma confirmed by pathology from May 2013 to May 2015 were selected, and treated with gemcitabine plus cisplatin chemotherapy and Ginseng and Astragalus assisted theropy.BRCA1 protein expression of all patients were detected, and relationship between the effect of chemotherapy and prognosis of patients with BRCA1 protein expression in lung cancer tissues were studied.Results In 80 cases, BRCA1 protein was positive in 40 cases, 40 cases were negative, CR 5 patients, PR 6 patients with BRCA1 positive expression, the remission rate was lower than the BRCA1 negative patients ( P <0.05 ) .80 cases of adverse reactions were seen as leukopenia, gastrointestinal symptoms (nausea and vomiting), abnormal liver function, BRCA1 expression of peripheral neurotoxicity, the incidence of complications in patients with positive expression were significantly higher than BRCA1 negative patients(P<0.05).N stage (P=0.03), BRCA1 gene (P=0.02) were independent risk factors of the prognosis of patients.Conclusion BRCA1 protein positive patients in lung cancer tissue had poor chemotherapy effect, more adverse reactions, and poor prognosis.

Aplastic anemia is a severe hematological disease characterized by bone marrow failure and pancyto-penia.Immunosuppressive therapy(IST)with antithymocyte globulin(ATG)and cyclosporine A(CSA)is the first -line treatment for patients who lack an HLA -matched sibling.One third of the patients has no response to IST and the high risk of ATG -related adverse effects may lead to ATG -related death.So it is necessary to explore the predictive marker of response to IST.A defined predictive marker may make the selection of treatment more reasonable and further improve the long -term efficacy.The relevant literatures were analyzed and summarized in recent years,in order to pro-vide a reference for clinical treatment and a baseline for prospective studies.

Skin toxicities are the most common adverse effects of epidermal growth factor receptor inhibitors(EGFRI).It can result in significant physical and psyehological discomfort,and even leads to interruption or dose modification,and consequently affect the curative effect. Nowadays this adverse effect has attracted lot of attention.It is proposed that clinical management and treatment measures for skin toxicities should be further studied to improve the patients life quality,and guarantee the continuity and best curative effect of the treatment.But more researches on the pathogenesis and its prognostic significance are still expected.

Due to the cultural lack in second documents'analysis of medical tangle,and the clinical teachers'three bases weakening,the facts that medical students fail to devote to communication between hospitals and patients,and the disjunction between the practice outline and clinical practice,trigger the reflection on the teaching professional level and the educational quality.First,we carry out the systematic construction of chnical practice teaching which includes aim orientation,curriculum design,resource integration,quality management and effectiveness evaluation.Second,we inelusively develop clinical professional skiUs and humanist accomplishment.Above all,we take the initiative to conform the teaching,including knowledge,technology,methods,and implement,to the incubation containing virtue,group,labor and pleasing,all of which promote a variety of needs of study and teaching

Faced with the rate’s drop of the Chinese clinical graduates’physician qualification examination and the experimental evaluation feedbacks from global medical education standard, we set up a research in clinical teaching bases’educational guarantee mechanism of medical colleges and universities. With the action research method and the descriptive studies in the definition of guarantee mechanism, the demand of graduates, the system of clinical lectures and the revolution of teaching mode, the standard of education, the system of basic condition datadetection, and the planning and the policy of clinical teachers’growth, we constructed the technical route of the leader’s supporting responsibilities, the teachers’professional roles and the students’ clinical teaching bases’ quality. We applied an empirical study in affiliated and non-affiliated hospitals of western and Chinesetraditional medicine and achieved predicted effort.

International services trade in the light of the principles of WTO makes a dif-ference in medical domain when confronting the direction of the global educational services. The Ministry of Education Project,"The Research of medical distance education and practice pattern in rural areas in west China",establishes an educational platform of modern service in central China, invests nursing human resources of west China and outputs vocational standard patients in east China,which provides school of medicine,especially English class of Chinese system,with abundant social teaching resources and has been adopted as Shanghai Human Resources Training Project.

Objective To investigate the effects of loop electrosurgical excision procedure(LEEP) on preg- nancy and delivery outcome in patients with CIN3.Methods Fifty-eight patients with CIN3 who were considering future pregnancies underwent LEEP from January 2003 to December 2006,and their following reproductive perfor- mances and delivery outcomes were observed.Results The mean time of the follow-up survey was 21 months(range from 6～42 months).There were 34 cases getting intrauterine pregnancies and 4 cases getting ectopic pregnancies. Among the 34 cases of intrauterine pregnancies,4 terminated by induced abortion and 1 by delayed abortion in early stage.21 cases delivered termed baby vaginally and 7 underwent cesarean section.No cervical dystocia had been re- ported.No disease recurrence had been found until the end of follow-up survey.Conclusion Loop electrosurgical ex- cision procedure is a safe and effective treatment for patients with CIN3.It will not effect the pregnancy and delivery outcome after LEEP.

Objective To investigate the antimicrobial and antioxidant activity of the water extract and ethanol extract of the powder of G.lucidum.Analysis and comparison of two kinds of antibacterial and antioxidative effects of the extracts.Methods G.lucidum powder was prepared by using a pulverizer and extracted with water and ethanol respectively.The inhibitory effects of water extract and alcohol extract of G.lucidum on the tested strains were determined by TTC method.The antioxidant activities of aqueous extract and ethanol extract of G.lucidum were determined by DPPH and FRAP.Results The minimum inhibitory concentration ( MIC) of the aqueous extracts and ethanol extracts of G.lucidum were 32 mg/mL and 16 mg/mL, respectively.The MIC for S.Aureus respectively was 64 mg/mL and 32 mg/mL, the MIC for M.luteus respectively was 32 mg/mL and 8 mg/mL, MIC for B.terom respectively was 64 mg/mL and 8 mg/mL, The MIC of B.subtilis respectively was 32 mg/mL and 8 mg/mL.The antioxidant activity of G.lucidum powder extract and ethanol extract showed good antioxidant activity, the scavenging radical capacities on DPPH of the water extract and ethanol extract were 56.22%and 20.67% at a concentration of 2 mg/mL ( P<0.5 ) , the FRAP value respectively were 3.52 and 3.77 mmol/mL.
