Objective To compare the clinical effect of valsartan/amlodipine combination or irbesartan/hydrochlorothiazide(HCTZ)combination in very elderly hypertensives.Methods After a 4-week placebo period,94 hypertensives,aged 75-89 years were random given valsartan 160 mg/amlodipine 5 mg or irbesartan 300 mg/HCTZ 12.5 mg for 24 weeks according to a rospective study.After 4 weeks,amlodipine or HCTZ was doubled in non-responders.Patients were checked every 4 weeks.At each visit,sitting,lying and standing blood pressure(BP),systolic BP(SBP)and diastolic BP(DBP)were measured. At the end of placebo period and treatment period,electrolytes and uric acid were evaluated.Results Blood pressure was significantly decreased in both treatment groups,however,there was no statistical significance between two groups.BP changes from lying to standing position were significantly greater in the irbosartan/HCTZ group(-17.2/-9.1 mmHg)than that in the valsartan/amlodipine group(-10.1/-1.9 mmHg,t=2.14,P＜0.05 for SBP and t=3.11,P＜0.01 for DBP vs.irbesartan/HCTZ).Potassium significantly decreased and uric acid significantly increased(-0.4 mmol/L,t = 2.33,P＜ 0.05 and+29.7μ mol/L,t =2.54,P＜0.05 vs.baseline,respectively)only in the irbesartan/HCTZ group.Conclusions Both combinations had similarly effective in reducing clinical BP in very elderly hypertensives.However,valsartan/amlodipine offered some advantage and less pronounced BP orthostatic changes and absence of metabolic adverse effects.

0.5). Conclusions There is an increasing trend of resistin level in healthy volunteers and patients with obesity, diabetes mellitus and hyperthyroidism in order Resistin also was a positive and an inverse correlation with BMI and resistance index respectively. These results support the hypothesis of Steppan that resistin causes insulin resistance and links obesity to diabetes, and that the high level of resistin in hyperthyroidism can help to explain the phenomenon of its insulin resistance.

Objective To investigate whether tumor necrosis factor-? (TNF-?) enhance the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9(MMP-9) in hepatic cancer cell line HepG2 or not. Methods Cultured HepG2 cells were treated by TNF-? with various concentration and time. The morphological changes of HepG2 cells were studied microscopically and the proliferation of HepG2 were detected by methyl thiazolyl tetrazolium (MTT). The expression of VEGF and MMP-9 mRNA in cultured HepG2 were determined by relative quantitative reverse transcription polymerase chain reaction. The VEGF and MMP-9 protein level in supernatants and in cytoplasm were determined by enzyme-linked immunosorbent assay (ELISA) and by immunocytochemical staining, respectively.Results There was a little morphological changes in HepG2 with TNF-? treatment, but no change of cell proliferation in corresponding time. The expression of VEGF and MMP-9 mRNA was enhanced gradually with the TNF-? concentration increasing, the VEGF and MMP-9 protein level in supernatants and in cytoplasm was elevated gradually with the concentration increasing. There was a dependance on the concentration when the concentration of TNF-? was lower than or equal to 10~4 U/L. Furthermore, the effect of promotion was close to peak when the TNF-? concentration up to 10~4 U/L; but no time-effect pattern observed. Conclusion TNF-? can enhance the expression of VEGF and MMP-9 at the level of mRNA and protein in hepatic cancer cell line.

Objective To study whether mechanical noise acting on the sacculus could enhance the SNR of the 8th nerve’s response.Methods Driving PZT by adding white noise of various level to periodic signals(f=100 Hz),the directly mechanical stimuli was give to the five sacculus submerged in a solution containing perilymph-like, and the afferent activity the 8th nerve was recorded.Results The SNR of the nerve signal was improved by addition nanometer-level noise to the periodic stimuli in all responsive animal(4.1 dB, on average).It was found that 2.3 nm of mechanical noise enhanced the response of the saccular nerve.Conclusion The addition of a few nanometers of noise to a periodic stimuli leads to a substantial improvement in the SNR of the nerve’s response.

Objective To examine the efficacy of applying clinical pathway (CP) teaching model in orthopedics clinical teaching.Methods Totally 64 medical undergraduates were randomized into 2 groups.The traditional teaching method and CP model were separately preformed on them.Their scores of theoretical,manipulation and case analysis exams at the end of internship were compared.Meanwhile the questionnaire of satisfaction degree also was conducted.Results Scores of exams and satisfaction degree were better in CP group than in classical group (P ＜ 0.05).Conclusions The novel CP model can promote the standardization and systematization of clinical teaching in orthopedics.It is conducive to evaluating teaching effect and performing teaching reform.Meanwhile,it is in accordance with the problem-based learning and can improve clinical teaching effect and satisfaction degree.

Objective To solve the problem of information store and forward, update for officers for collect information expediently. Methods Information is stored by using two dimensions tag's technique and is taken in deck form. Results The tag was used in cosmically practice satisfactorily. Conclusion It solves the problem of one dimensional medicinal tag on no-semantide and update and is advantageous to obtain the wounded information for the base hospital and the field battle medical treatment team.

Objective 70 realize the fast collection and management of the basic wounded information in the field treatment. Methods Two-dimensional electronic medicine tag was used as a massage loader. The wounded information was analyzed with a program reader, and the basic personal and cure information were shared with the information management system. Result The system was used in the massive discipline for the first time, fulfilled the wounded information record, analysis, transfer, and the management of the cure information with 80 items. Conclusion The correctness of the basic massage record and analysis is full percent. The manage progress of the system accord with the field condition.

Objective To realize medical information collection and digital management in field battle and the fundamental information and cure of medical staff of emergency medical, equipment and the wounded were included in it. Methods The collecting information were transmitted to computer through wireless connection and manage the information with Delphi7 procedure. Results The system was used firstly in large-scale practice and completed the information transcription and management on elementary and cure in hundred of wounded. Conclusion The information is up to the mustard of field and it has established base on cure information in digital management.

Objective To collect and analyze the basic information of two dimensions electronics medicine tag, and send out the analytical information to field battle information management system and share with the resources. Methods The information were collected, analyzed and sent by adopting MC50 and some software. Results The information of collection and analysis on 80 cases was completed by the device in large-scale practice. Conclusion The device usage is convenient, the function is stable, and the rate of collection and analysis is 100%.

Objective To construct human Cystatin C expression vector and make primary protein purification. Methods A 380 bp cDNA fragments encoding Cystatin C were isolated by RT PCR from human placenta tissue and then inserted into pPIC9 vector. Recombinant pPIC9 Cystatin C was transformed into Pichia pastoris strain GS115. Secreted soluble Cystatin C was produced by induction of the AOX1 promoter with methanol. Recombinant Cystatin C was purified by Hitrap SP cation exchange chromatography. Results The expression level of Cystatin C reached 16 mg/L. The stability of Cystatin C is 3 days in expression system. SDS PAGE revealed that Cystatin C was expressed up to 60% of the total soluble protein. After purified by Hitrap SP cation exchange, the recovery rate was 40.5%. Conclusion Cystatin C has a high secretion in Pichia pastoris yeast and could be recognized by polyclonal antibody of native human Cystatin C. After purification,this protein can be used as a standard and antigen to develop immunoassay for human Cystatin C in serum.
