In order to raise international comprehensive medical talents to have strong competition capability,the bilingual teaching is on the rise in the domain of medical education. Questionnaire-based survey among the 5-year-proguam medicinal undergraduate students was conducted to investigate the students'learning condition,acquaintanceship and requirements on the bilingual teaching so as to further reform and explore ways to improve the quality of bilingual teaching

Objective To investigate the prevalence of urine abnormalities for school children in Lanzhou and evaluate the signiifcance of urine screening. Methods During 2012-2013, urine from 10795 students were collected, and screened by urine reagent paper. Two weeks later, repeated screening was conducted in those who had abnormal result in the ifrst screening. Children with both results being abnormal were submitted to urine routine tests in local hospitals. Results In the ifrst screening of school children, 1653 (15.31%) children were urinary occult blood positive, 516 (4.78%) had urinary protein, 112 (1.04%) had occult blood with proteinuri and 743 (6.88%) had white cells in urine. In the second urine screening, the positive rate of occult blood was 7.55%(815 ), urinary protein was 2.13%(230), occult blood with proteinuria was 0.69%(74) and white cells in urine was 2.51%(271). Four hundred and iffty-ifve students in 1359 were submitted to urine routine tests. Thirty-two children had pyuria, 147 had hematuria, 23 had proteinuria and 13 had occult blood with proteinuria. Thirteen cases of chronic kidney disease were found in the follow-up. The incidence of urine abnormalities was signiifcantly higher in junior middle school than in primary school. Conclusions Urine screening is an effective way to ifnd asymptomatic kidney disease and urinary tract infection. Follow-up should be strengthened.

OBJECTIVE: To investigate the uptake of self-assembled sodium alginate(SA) nanoparticles labeled by FITC(sSAN-FITC) in Caco-2 cells and the influencing factors.METHODS: Fluorescence microscope was utilized to exam the uptake of sSAN-FITC in Caco-2 cells.Multifunction continuous spectrum enzyme-linked immunosorbent assay system was used for the detection of the fluorescence intensity of FITC in the cells and quantitative assay of the effect of sSAN concentration,its action time and pH on the uptake of sSAN-FITC in Caco-2 cells,with blank group as control.RESULTS: Pictures of Caco-2 cells taken by fluorescence microscope showed uptake of sSAN-FITC by Caco-2 cells.As compared with blank control group,among the 3 factors,the fluorescence intensity increased with the increase of the sSAN concentration and the prolonging of the action time(P

Objective To investigate the positive ratio of urine and gender difference of chronic kidney disease(CKD) with children in Lanzhou,a heavy pollution and underdeveloped city in northwest of China.Methods Through the Multistix 10 SG,the morning urine of the children were detected,which aged from 12 to 13 years old.Results The positive ratio of urine was 14.9％ in subjects,18.2％ in girls and 12.8 ％ in boys respectively.Furthermore,the positive ratio in girls showed statistically significant higher than boy's.(x2 =21.77,P ＜ 0.01).Espcially,the ratios of hematuria and pyuria significantly increased in girls (x2 =17.52,P ＜ 0.01;x2=7.95,P ＜ 0.01).Conclusion The gender difference of the positive rate of urine was existed in our large samples.And there is a higher prositive rate of hematuria and pyuria in the girls.This investigation will enrich the epidemiological data of CKD in children(12 ～ 13 years old)in Lanzhou city.

Chinese patent medicine with double identity was a special phenomenon, and many preparations not only were prescription drugs but also over the counter ( OTC) drugs, which brought a lot of trouble. Based on statistics of list of OTC medicines of CFDA, related varieties, route of administration and functions of these drugs were searched. The causes of insufficient were analyzed and the potential risk was investigated. To ensure the safety of drug usage for the patient, risk management system should be set up by improving the technical requirements for registration, improving the drug labels and manuals, playing the role of pharmacists in pharmacy services and raising awareness of doctor and patient for these drugs.

Acute myeloid leukemia (AML),the most common disease in acute leukemia,is a highly heterogeneous invasive hematological disease.The t(8;21)(q22;q22) translocation is the most common chromosomal translocation in AML,generating AML1-ETO fusion gene and encoding AML1-ETO fusion protein.This article summarizes the two-hit hypothesis in AML occurrence,the pathogenesis of t(8;21)AML,all features involved in t(8;21)AML,and the function of the components in AML1-ETO fusion protein,providing important basic information for the treatment and prognosis of t(8;21)AML.Meanwhile,this article also summarizes the progress of next generation sequencing technique in leukemia,providing a new technique for the accurate therapy of (8;21)AML.

Objective To establish the paclitaxel-resistant gastric cancer cell(HGC-27/PTX) and to investigate the changes of characteristics before and after resistance,as well as the possible resistant mechanisms.Methods The paclitaxel-resistant gastric cancer cell HGC-27/PTX was established by increasing paclitaxel dose gradually and intermittently.The IC50 (50% inhibitory concentration) and cell cycle were determined by CCK-8 assay and flow cytometry,respectively.The differentially expressed genes (DEGs) and signaling pathways were analyzed using RNAseq.Results The establishment of HGC-27/PTX cells lasted 9 months,and the sensitivity of paclitaxel of HGC-27/PTX cells was significantly lower than parental cells (P<0.05).Compared to parental cells,the morphology of HGC-27/PTX cells was slightly different,and the proportion of S and G2/M phase was obviously increased (P<0.01).A total of 274 DEGs were identified between the resistant and parental cells with 130 genes up-regulated and 144 genes down-regulated.DEGs were significantly enriched in extracellular matrix (ECM)-receptor interaction(P<0.001) and PI3K-Akt signaling pathways (P<0.05),which could provide evidences for reversing paclitaxel resistance.Conclusions The paclitaxel-resistant gastric cancer cells HGC-27/PTX was established with stable culturein vitro,which provides an ideal model for future study on the mechanism of drug resistance.

ABSTRACT:Objective To study the effect of continuous nursing by wechat in patients with esophageal carcinoma operation.Methods A total of 277 patients with esophageal cancer were di-vided into experimental group and control group.All the patients received routine discharge guid-ance before discharge.The 136 patients in the control group were phoned for one time at the end of 2 weeks,the 1st month,the 2nd month and the 3rd month and were provided instruction for regu-lar diet.The 141 patients in the experimental group received continuous nursing once a week to in-struct diet intervention and health guidance by wechat from 2 weeks to 3 months after discharge. The condition of health knowledge,the ability of self-nursing and the rate of complications be-tween the two groups was compared.Results The incident rates of health knowledge,the ability of self-nursing and the rate of complications in the experimental group were higher than that in the control group.Conclusion Wechat is a convenient way to follow up patients.Continuous nursing by wechat can greatly enhance the patients’self-nursing ability and significantly decrease the rate of anastomotic stricture after esophageal cancer operation.
