OBJECTIVE:To evaluate clinical utilization and blood concentration monitoring of vancomycin in our hospital. METHODS: By retrospective survey method, the clinical information (primary diseases, bacteriological culture, blood concentration of vancomycin, clinical efficacy, renal function) of 41 inpatients who had been treated with vancomycin and their blood concentrations from Nov. 2005 to Dec. 2008 were analyzed statistically. RESULTS: The total response rate of vancomycin was 65.0%. The peak concentration of 62.7% cases were below 25 mg?L-1 while the valley value of 55.2% cases were below 5 mg?L-1. The incidence of renal dysfunction after treatment was 12.2%. CONCLUSION: The consumption and blood concentrations of vancomycin are close to low level in our hospital. It should be paid attention to the blood concentration monitoring of vancomycin to achieve an ideal individual administration according to clinical practice.

Objective:To investigate the influence of radiotherapy on immunity of patients with cervical cancer Methods:22 cancer patients and 20 patients with gynecological benign tumor were immunothenotype by flow cytometry Results:There was no obvious difference in immunity between cancer patients and control group After radiopherapy, ratio CD3 +/CD4 + decreased and the number of CD8 + and NK cells increased in cancer patients Conclusion:No immunodepression appeared in patients with cervical cancer before therapy Radiotherapy decreased immunity, which indicates adjuvant immunotherapy should be given during radiotherapy

Aim To investigate the reversal effect of GP on the activity of P-gp in MDR-associated tumor cells and to develop a useful approach to inhibit the drug efflux in MDR-associated tumor cells.Methods MTT assay was used to detect the effect of GP on the cytotoxicity of cisplatin(DDP),vincristine(VCR) and doxorubicin(DOX).Flow cytometry was used to determine the influence of GP on the intracellular accumulation of DOX.Results GP synergistically increased the cytotoxity and the intracellular accumulation of DOX in K562/DOX cells;GP also increased the cytotoxity of DDP,DOX,and VCR in A549/DOX cells.However,the effect was relatively weak.Conclusion GP could increased the cytotoxity and the intracellular accumulation of chemotherapeutic drugs in MDR-associated tumor cells.GP may be a promising MDR modulator.

Chloral hydrate is a safe and effective sedative hypnotic medicine. Patients can usually calm down or fall asleep quickly after taking it. It has great clinical value and practical needs in children ’s sedation. However ，the nature of chloral hydrate itself and various factors such as ambient temperature and light affect its stability of the preparation ，most of chloral hydrate preparations are still used in clinic in the form of hospital preparations. Therefore ，developing chloral hydrate preparation with single dose ，long validity period and automatic mass production is the prospect and goal of its subsequent development. Based on it，this study collects and reviews the relevant literatures on various preparations of chloral hydrate and their clinical application by searching the Chinese and English databases.

We aimed to investigate the relationship of dietary zinc intake with new-onset hypertension among Chinese adults. A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey were included. Dietary intake was assessed by three consecutive 24-h dietary recalls combined with a household food inventory. Participants with systolic blood pressure ≽ 140 mmHg or diastolic blood pressure ≽ 90 mmHg or diagnosed by a physician or under antihypertensive treatment during the follow-up were defined as having new-onset hypertension. During a median follow-up duration of 6.1 years, 4269 participants developed new-onset hypertension. Overall, the association between dietary zinc intake and new-onset hypertension followed a J-shape (P for non-linearity < 0.001). The risk of new-onset hypertension significantly decreased with the increment of dietary zinc intake (per mg/day: hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.88-0.98) in participants with zinc intake < 10.9 mg/day, and increased with the increment of zinc intake (per mg/day: HR 1.14; 95% CI 1.11-1.16) in participants with zinc intake ≽ 10.9 mg/day. In conclusion, there was a J-shaped association between dietary zinc intake and new-onset hypertension in general Chinese adults, with an inflection point at about 10.9 mg/day.
