Objective This present study explores and evaluates the effect of preliminary implementation in the clinical therapy programs for patients with chronic Keshan disease (CKD) in the disease seriously-affected endemic areas.Methods In 2010,seventy-six CKD patients with heart failure were chosen from Huangling and Xunyi Counties in Shaanxi Province,where incidences of CKD were high.Besides taking sodium selenite,all patients were given treatment with fixed prescription,which included angiotensin-converting enzyme inhibitor (captopril),β-blocker (propranolol),diuretics (hydrochlorothiazide,spironolactone) and cardiac (digoxin) for 4 months.The changes before and after treatment were analyzed,which included the changes of heart function by the United States of America New York Heart Association(NYHA) fractionation,cardiothoracic ratio,electrocardiogram,left ventricular ejection fraction(EF) and fractional shortening(FS).The therapeutic effect was subsequently evaluated.Results Seventy-four cases of the seventy-six CKD patients completed the treatment observation.The improvement rate of heart function was 81.1％ (60/74) after treatment.The elimination rates of ectopic rhythm,conduction block and ST-T changes were 37.5％ (9/24),2.7％ (1/36) and 26.9％ (7/26),respectively.The cardiothoracic ratios of heart function NYHA Ⅱ,Ⅲ and Ⅳ were 0.504 ± 0.051,0.572 ± 0.054 and 0.632 ± 0.063 before treatment.After treatment,the cardiothoracic ratios were 0.486 ± 0.048,0.538 ± 0.046 and 0.607 ± 0.048,which were reduced in all groups (t =2.643,6.641,3.005,all P ＜ 0.05),while the D-value of cardiothoracic ratio changes before and after treatment was not significantly different(F =3.005,P ＞ 0.05).Both the mild reduction group(35％≤EF ＜ 50％) and the moderate-severe group(EF ＜ 35％) EF were (43.62 ± 4.58)％,(27.57 ± 3.69)％ before treatment and were (48.21 ± 10.01)％,(36.57 ± 6.60)％ after treatment,EF were increased in the two groups,while the changes before and after treatment were significantly different(t =-2.911,-3.334,all P＜ 0.05).The EF D-value of the two groups was (4.59 ± 8.48)％ before treatment and was (9.00 ± 7.14)％ after treatment,which were not significantly different(P ＞ 0.05).FS was higher compared with pre-treatment in FS reduction group(FS ＜ 25％) and the changes before and after treatment[(19.75 ± 2.88)％,(21.92 ± 5.67)％] were significantly different(t =-2.297,P ＜ 0.05).Conclusions This study shows that the feasibility of clinical treatment of patients with CKD is very promising.The treatment of fixed prescription is effective.

Biochemistry is a very practice-oriented courses,but the experiment has high cost,long cycle characteristics,and thus help ease the creation of virtual laboratory experiments and the conflict between teaching resources and the demand.We rely on our campus network to build a virtual biochemistry laboratory,with a view to promoting the biochemistry course construction and reforming the teaching methods

The teaching reform in college is calling for changes in students' learning styles and teachers' teaching methods.It is very important to change teacher' s educational concept and transform teacher' s role in the teaching process in order to completely change the form and content of nutrition and food hygiene course.It means we should only change traditional teaching approaches into problem based learning or inquiry teaching but also summarize the teaching content and integrate the theory with practice.

The purpose of this study was to reveal the current situation of health technology transfer in Shanghai hospitals,and to analyze the problems and needs.Questionnaire and interview were adopted for the study.We found that in the past 3 years,the transformation rate of patent technologies at Shanghai Tertiary Hospitals was 5.88％.The transfer routes mainly involves proactive enlist of enterprises by project leader,technology brokerage,exhibitions of patents achievements,friends' recommendation,etc..The main factors impacted the transfer included poorer quality of patent,lacking efficient management,and lacking channels for transfer.In order to improve the transfer of patents,hospitals need to provide information service,technology assessment,project packaging,patents application,consultant,and relevant trainings etc.Other things that could promote health technology transfer are to improve scientific research system,to enhance the quality of scientific achievements,and to develop technology brokerage.

Objective To set up the methods of establishing rat primary benign prostatic hyperplasic glandular epithelial cell line.Methods Male spontaneously hypertensive rats were raised to 29 weeks,and then evaluated the situation of BPH with HE staining.The prostate tissue from ventral prostate lobe was aseptically removed,dissected,minced,and then dissociated in collagenase type Ⅰ.Isolated cells were collected,seeded in WAJC-404 and PrEGM medium separately,then cultured and passaged.Specificity of primitive cultured prostatic epithelial cells was identified by cell immunochemistry with CK8/18,and the cell growth curves were drawn.Then the situation of growth of the two prostatic hyperplasic glandular epithelial cell lines were analysed and compared.Results The prostatic hyperplasic glandular epithelial cell lines of the spontaneously hypertensive rats in WAJC-404 and PrEGM medium were successfully primarily cultured,purified and passaged in vitro.Cell immunochemistry proved that the cell lines specifically express cytokeratin 8/18.Cell growth curve showed that prostatic epithelial cells in PrEGM,compared with prostatic epithelial cells in WAJC-404,possessed better cell morphology,more exuberant cell vitality,faster growth rate to enter the logarithmic growth period(4 d vs.7 d)and higher peak of cell growth curve(15.3× 104/ml vs.12.8×104/ml).Conclusions Rat primary benign prostatic hyperplasic glandular epithelial cell line can be established conventionally in vitro.PrEGM medium is more suitable for primary culture of the rat benign prostatic hyperplasic glandular epithelial cell line than WAJC-404 medium.

Objective To observe the evaluation of early chemoradiotherapy efficacy in uterine cervical cancer by different b-value combination.Methods Thirty uterine cervical cancer patients who were treated with chemoradiotherapy received conventional MRI and diffusion weighted imaging (DWI) before treatment,after 2 weeks treatment and after treatment.The patients were divided into complete remission (CR) group (15 cases),partial remission (PR) group (9 cases),stable disease (SD) group (6 cases) according to the changes in tumor size after 9 months of treatment.The tumor size and apparent diffusion coefficient (ADC) of uterine cervical cancer were measured at each examination among the 3 groups.All ADC were calculated with b =0,600 s/mm2 and b =0,1000 s/mm2.According the receiver operating characteristic (ROC) curve,chemoradiotherapy efficacy and prognosis value of different b-value of ADC chart in uterine cervical cancer were compared.Results There were no significant differences in ADC of b =0,600 s/mm2 ADC chart and b =0,1000 s/mm2 ADC chart before treatment and after 2 weeks treatment in the 3 groups (P＞ 0.05).ADC increase rate after 2 weeks treatment in CR group was significantly higher than that in PR group and SD group (0.35 ± 0.10 vs.0.22 ± 0.10 and 0.21 ± 0.08,0.28 ± 0.08 vs.0.14 ±0.04 and 0.16 ± 0.02,P ＜ 0.05).There was no significant difference between PR group and SD group (P ＞0.05).The decrease rates of tumor diameter after 2 weeks treatment in CR,PR and SD group were 0.36 ±0.18,0.33 ± 0.17 and 0.24 ± 0.09,there were no significant differences (F=1.151,P ＞ 0.05).After 2 weeks treatment,at b =0,600 s/mm2 ADC chart,when liminal value of ADC was 0.211 × 10-3 mm2/s,ROC area under curve was 0.976,sensitivity was 85.6％,specificity was 100.0％; at b =0,1000 s/mm2 ADC chart,when liminal value of ADC was 0.181 × 10-3 mm2/s,ROC area under curve was 0.979,sensitivity was 85.6％,specificity was 100.0％.The accuracy of two kinds of ADC chart evaluation of uterine cervical cancer early chemoradiotherapy efficacy was higher,and the effect was similar.Conclusion The ADC increase rate after 2 weeks treatment can be used to predict the early chemoradiotherapy efficacy of uterine cervical cancer,and the value of two kinds of ADC chart of different b-value is similar.

Objective To report the clinical,electrophysiological and genetic features in a family with Charcot-Marie-Tooth disease type 1D (CMT1 D).Methods The proband,a 53-year-old man who was found with pes cavus when he was 15 years old,presented with weakness in both lower limbs at the age of 37,aggravated and numbness in legs at the age of 50.His daughter was confirmed pes cavus in her teens and weakness in both lower limbs at the age of 18.Electrophysiology and next generation sequencing were performed in the proband.Results Electrophysiological results of the proband showed demyelinating change in motor and sensory nerves.Latency prolongation was found in bilateral waves Ⅲ,V and abnormal differentiation in bilateral waves Ⅰ of brainstem auditory evoked potential,while both interpeak latencics of Ⅲ-Ⅴ were normal.DNA analysis revealed a heterozygous 1141C ＞ T mutation in exon 1 of early growth response 2 (EGR2) gene in both of the proband and his daughter.Conclusions The onset age of Arg381Cys mutation in EGR2 gene could be at juvenile with weakness in both lower limbs.The phenotype of CMT1D is mild and progressive slowly.

Objective To investigate the antimicrobial resistance of Haemophilus influenzae in Peking Union Medical College Hospital for rational clinical treatment.Methods A total of 223 strains of H .influenzae were collected from patients from Jan-uary 2008 to December 2011.The antimicrobial susceptibility was tested by Kirby-Bauer method.Production of beta-lactamase was detected using nitrocefin disks.WHONET 5.6 software was used to analyze the data of susceptibility testing.Results Tri-methoprim-sulfamethoxazole and tetracycline were the two antimicrobial agents to which the H .influenzae strains were most resistant.Theβ-lactamase positive ampicillin resistant strains accounted for 15.9 %,andβ-lactamase negative ampicillin resist-ant strains accounted for 8.9%.Conclusions H .influenzae is mainly isolated from respiratory specimens.Majority of the anti-microbial agents still show good antibacterial activity against H .influenzae strains.However,H .influenzae isolates are highly resistant to trimethoprim-sulfamethoxazole and tetracycline.
