Objective To establish HPLC method for fast, effective, simultaneous determination of Vancomycin and Norvancomycin in serum. Methods The separation was achieved on the Hypersil ODS2(250 mm ×4.6 mm,5μm)with methanol-acetonitrile-a mixture of potassium phosphate (9.5:2.5:88) as the mobile phase.The flow rate was 1.0 mL/min.The UV detecting wavelength was 280 nm.The temperature of the column was 35 ℃. Vancomycin and Norvancomycin were used as the internal standard for each other .Results Vancomycin and Norvancomycin blood concentration were in well linearity in the range of 1.25-100μg/mL,R2 =0.9996.The average method recovery rate of three concentrations were 96.88%,99.50%,105.01%respectively, the average method recovery rate of three concentrations were 94.40%,103.90,103.81%respectively, the intra-day and inter-day RSD were less than 5%.Conclusion The HPLC method is proved to be simple,sensitive, accurate and precise in which little blood sample is taken, thus it is suitable for the therapeutic drug monitoring(TDM) and pharmacokinetic study of Vancomycin and Norvancomycin.

A long term follow-up with these cases was carried out.Results:Most patients got better outcome.Conclusion:Fluoxetine would be an important supplement antiepileptic drug and have value for further clinical and experimental research.

BACKGROUND: Critical incidents are natural and man-made disasters arising suddenly, which are beyond the ability of the individuals to resist or control. In the situation of stress, individuals feel stuck, and are unable to control the situation.OBJECTIVE: To confirm the assessment model of stress response to critical events and the interventional effect of social support, general self-efficacy and coping efficacy.DESIGN: A randomized sampling, questionnaire-based investigation.PARTICIPANTS: We selected 1016 college students of 17 provinces or cities including Beijing, Guangzhou, Hefei, Jilin, Jiangsu, Jiangxi , Liaoning, Sichuan, Inner Mongolia, Shandong , Shanghai, Hebei, Tianjin,Wuhan, Zhejiang , Chongqing and so on as subjects. Totally 708 college students selected from the above regions received the same survey one year later.METHODS: Depression and anxiety state of the subjects were investigated with Center for Epidemiological Studies Depression Scale (CESD)and Anxiety Inventory (SAS) during SARS. Social support condition was investigated with Social Support Rating Scale, authorized by Xiao Shuiyuan. Related items were amended considering used among college students. The subscale was integrated into 3 subscales including group-support, friend-support and social support utilization. One year later, stress response to SARS was investigated again with self-made coping efficacy scale, self-esteem scale and self-efficacy scale and SARS Stress Response Questionnaire, which included 13 items measuring the students in three aspects: cognitive evaluation to SARS epidemic, such as "I believe human beings can conquer SARS in the end"; panic to SARS, like "worrying about SARS sweats me and makes me feel shiver sometimes"; and defense response to SARS, as "In order to prevent SARS, I have to wear respirator in the public". As far as cognitive, panic emotion and defense behaviors were concerned. The coping efficacy developed by the author covered 18items, such as "I'm afraid that I can not deal with things", "I have enough confidence to conquer any difficulty", and namely as friability, confidence and intelligence.RESULTS: ① The two investigated results were compared through assessment of covariation. There was a significant difference in cognitive condition, panic emotion and defense behavior; that was to say, the stress response to SARS had been obviously relieved . ② Social support and SARS stress response model x2=8.654,df=4,P=0.07;criterion fit index NFI= 1, RFI =0.997 and IFI =1, RMSEA=0.034. ③self-efficacy confirmative factor analysis showed the following: x2=0.536,df=2,P=0.765;x2/df=0.268, NFI=1, RFI=1, IFI=1 and CFI=1, RMSEA=0.000. ④The discriminating and convergent validity of coping efficacy questionnaire was as follows. The coefficient was 0.633 with general efficacy questionnaire, 0.530 with self-respect (SES), 0.481 with CESD, 0.387 with anxiety (SAS), and -0.003 with living events. ⑤ A structural equation model about general self-efficacy, coping efficacy and SARS stress response was established: x2 =2.722 df=3, P=0.437; NFI=1, RFI=0.999,IFI=1, CFI=1, RMSEA=0.068. The model fitted well. According to the data, coping efficacy affected SARS stress response negatively (the coefficient was -0.59)CONCLUSION: ① The three-dimensional assessment model assessed the stress response to critical incidents including cognitive adjustment, emotional response and behavioral tendency. The three-dimensional model stood the test while assessing SARS stress response. Compared with the assessment of emotional disorders, such as depression and anxiety, the model was more sensitive. ②Social support played a vital role in the stress response to critical incidents as a buffer or a regulator. It showed more influence on emotional disorders than on SARS stress response. ③Coping efficacy was a measurable intervening variable, which deserves more attention to in the stress response to critical incidents. Compared with general self-efficacy, coping efficacy had a greater intervening effect on SARS stress response.

AIM: To investigate the influence of aspirin on the efficacy of captopril in the treatment of chronic congestive heart failure (CHF). METHODS: 74 cases of CHF were divided into 2 groups depending on whether aspirin was administrated before captopril was given, then all patients were given captopril 12.5 - 25 mg , tid, for 28 days. RESULTS: In aspirin group, marked effective rate was 46.7 %, and total effective rate was 70%, superior to that in no aspirin group (P

Objective: To explore the value of combined treatment of advanced hepatic carcinoma. Methods:117 cases with advanced hepatic carcinoma underwent a combined treatment by radio frequency ablation(RF),percutaneous ethanol injecton(PEI),transcatheter hepatic arterial chemoembolization(TACE)and transultrasonic portal vein chemoembolization (SPVE).The comparison was made between this treatment and that of TACE alone in terms of size of tumor ,changes of blood supply and clinical effects before and after each of these two treatments. Results: After three months,Ultrasonographic examination showed that the tumor size decreased by 25.0% was 87.2%.The disappearing rate and decreasing rate of blood supply of tumor was 88.0%; AFP turning-negative rate was 78.3%.The follow-up survey showed that one-year and two-year survival rates for combined therapy were 73.5%and 62.4% respectively ,significantly higher than that for the control TACE group 59.4%and 32.6%. Conclusion: The combined treatments are effective ways for carcinoma treatment. Color Doppler imaging is important to guide and assess the treatment.

Objective: To investigate effects of glucose and free fatty acid at different concentrations on phosphorylation of adenosine-5′-monophosphate activated protein kinase(AMPK) and acetyl CoA carboxylase(ACC) in INS-1 cells,and effects of globular adiponectin on phosphorylation of AMPK and ACC.Methods: INS-1 cells were cultured and treated with 5 mmol/L glucose or 0.25 mmol/L free fatty acids,and time courses and dose responses of different dosages of glucose and fatty acid on phosphorylation of AMPK and ACC were measured.We measured the effects of the pharmacological AMPK activator AICAR(5-aminoimidazole-4-carboxamide-riboside) and globular adiponectin on phosphorylation of AMPK and ACC.Results: Glucose and fatty acid at different concentrations inhibited the phosphorylation of AMPK and ACC at the end of 60 min,but AICAR increased the phosphorylation of AMPK and ACC significantly,while 2.5 mg/L globular adiponectin increased the phosphorylation of AMPK and ACC by 23%(P
