The paper aimed to find out the present situation of bilingual teaching in higher medical education of the local medical college for nationalities and the results of the questionnaire showed that there were still some problems in the bilingual teaching education in these years.And some constructive suggestions were put forward.

Objective To research the effect of letrozole combined with clomiphene on women with polycystic ovary induced infertility and the effect on matrix metalloproteinases-9(MMP-9),vascular endothelial growth factor(VEGF)and hepatocyte growth factor(HGF)levels.Methods 108 patients with polycystic ovary syndrome combined with infertility from February 2013 to August 2015 in our hospitolwere divided into control group and experimental group by lottery,54 cases in each groups,control group treated with clomiphene,the experimental group based on control group treatment with letrozole,the linical curative effect,MMP-9,VEGF and HGF level,sex hormones,insulin resistance index,adverse drug reactions of two groups were compared.Results The number of ovulation,advantage of ovulation number,normal rate of menstruation,ovulation rate and pregnancy ratesofin experimental group was higherthan the control group,the difference was statistically significant(P<0.05).The MMP-9,VEGF and HGF levels of experimental group was lower than the control group,the difference was statistically significant(P<0.05).The sex hormone level of experimental group was better than that of control group(P<0.05).The adverse reactions was no differences between the two groups.Conclusion The efficacy of letrozole combined with clomiphene in treatment of polycystic induced infertility,can inhibits MMP-9,VEGF and HGF expression,and with high safety.

OBJECTIVE:To study the general pattern and characteristics of adverse drug reactions(ADR) induced by tinidazole.METHODS:Tinidazole-induced ADR cases reported in the internal pharmaceutical journals retrieved from Jan.1994 to Jun.2006 were analyzed statistically.RESULTS:The ADR induced by tinidazole were diversified in clinical manifestation,but allergic response was the most common type,followed by the lesion of nervous system and digestive system etc.CONC-LUSION:Clinicians should attach great importance to the ADR induced by tinidazole.

As the increasing of digital imagilag modalities,a close-at-hand challenge to deal with is the storage and transmission requirement of enormous data of medical images.Compression is one of the indispensable techniques to solve this problem.A comprehensive review and discussions are made in this paper over the medial image compression techniques applied in medical image domain,including the latest achievements in this field.Different compression algorithm including ROI-based coding,lossless compression,DWT,neural net are introduced and some quality evaluation methods are introduced.Foreground of the field is given from our point of view.

Objective:To investigate the expression and correlation of EHD2 and E-cadherin in hepatocellular carcinoma (HCC). Meth-ods:Western blot and immunohistochemistry were used to detect the expression of EHD2 and E-cadherin in HCC specimens and adja-cent noncancerous tissues. The correlations of EHD2 and E-cadherin with the clinicopathological characteristics and prognosis of pa-tients were further analyzed using Pearsonχ2 test and Kaplan-Meier method. Results:EHD2 expression, along with E-cadherin, was markedly reduced in HCC tissues than in adjacent noncancerous tissues. Moreover, EHD2 and E-cadherin expression were correlated with histological grade, microvascular invasion, and lymph node metastasis (P<0.05). Kaplan-Meier survival analysis showed that HCC patients with decreased EHD2 and E-cadherin expression had shorter overall survival time than those with higher expression. Conclu-sion:The abnormal expression of EHD2 and E-cadherin possibly promote HCC. Detection of EHD2 and E-cadherin may be valuable for diagnosing HCC and evaluating malignancy extent and prognosis.

0.05). Conclusions Autop-hagy/lysosomal pathway was activated immediately after recurrent seizures as indicated by the elevated expression of Beclin1 in cerebral cortex. 3-MA was involved in the regulation of autophagy/lysosomal pathway by down-regulating the expression of Beclin1.

Objective: To study the effects of light intensity on the compressive strength and tensile strength of light -curing composite resin. Methods: 25 samples of Shade A (Dentsply,USA) light-curing composite resion in the size of 10?5?1(mm) and equally divided into 5 groups.The light intensities (mW/cm 2?40 s) of 300,500,800,300 mW/cm 2?10 s+500 mW/cm 2?30 s,300 mW/cm 2?10 s+800 mW/cm?30 s were applied during the light-curing in group 1,2,3,4 and 5 respectively.The compressive strength and tensile strength of of the samples were measured by computer-controlled electronic testing machine (type WDW-100). Results:The compressive strengths (MPa) of group 1,2,3,4 and 5 were 228.68?20.25,274.67?6.99,380.53?9.81,345.47?10.71 and 414.06?29.34 respectively (P

Objective To study the chemical constituents in Crepis turczaniowii C. A. Mey. Method The constituents were isolated and purified by column silica,polystyrene resin RA and polyamide columbine chromatography,and the structures were identified by physicochemical data,MS and NMR. Result Two compounds were obtained in the Petroleum ether fractions as ?-taraxasteryl acetate (Ⅰ) and ?-sitosterol (Ⅱ),and one compound was obtained in the n-BuOH fractions as phillyrin (Ⅲ). Conclusion All above compounds are obtained from the plants of Crepis turczaniowii C. A. Mey. for the first time. Ⅲ is isolated from Crepis L. for the first time.

Objective To establish the quality standard for Zhilining pill. Methods TLC was employed to identify Radix Sophorae Flavescentis and Radix Aucklandiae while the content of dehydroandrographolide in Zhilining pill was detemined by HPLC. Results TLC findings of Radix Sophorae Flavescentis and Radix Aucklandiae showed the spots of same colors as those developed in the corresponding places of control medical materials. Good liner was observed when the samplesize of dehydroandrographolide was within the range of 0.062～1.550 ?g (r =1.000 0). The average recovery rate was 98.00% with RSD=0.90%. Conclusion The method is simple, accurate, stable, reliable and with good reproducibility, which can be used for the quality control of Zhilining pill.
