ABSTRACT
Objective To investigate the nutritional risks, prevalence of undernutrition, and nutritional interventions among inpatients in departments of nephrology in some hospitals in Guangzhou, with an attempt to provide evidences for the nutritional support of patients with kidney diseases. Methods Totally 378 adult patients in departments of nephrology in Guangzhou were enrolled in this study by fix-point consecutive sampling. Nutritional Risk Screening 2002 (NRS 2002) was applied for nutritional risk assessment. Nutrition risk was defined by NRS score ≥3 and undernutrition by BMI ＜ 18.5 kg/m2 or serum albumin ＜ 30 g/L. Nutritional interventions were also evaluated in all patients. The relationship between nutritional risk and nutritional support was analyzed. Results The overall prevalence of undernutrition was 21.7% and the nutritional risk was 41.3%. They were especially high among patients with chronic kidney dysfunction (24. 3% and 60. 7% , respectively). The nutritional risk was 42. 3% in patients accompanied with diabetes (P＞0. 05). Of these 378 patients, 102 (27.0%) received nutritional interventions, in which the nutritional support rate was 50. 0% (78/156) for patients with nutritional risks and 10. 8% (24/222) for those without nutritional risks. Conclusions The nutritional risks and prevalence of undernutrition are high among inpatients in the departments of nephrology in hospitals in Guangzhou. Proper application of nutritional interventions remains a concern. Evidence-based guidelines are required to improve this situation.
ABSTRACT
OBJECTIVE:To compare the costs and effectiveness of4treatment regimens for hypertension.METHODS:212cases of hypertension were randomly divided into4groups,group A treated with amlodipine,group B treated with fosino?pril,group C treated with candesartan cilexetil,and group D treated with losartan;the curative effects in each group were ob?served and cost-effectiveness analyses were made.RESULTS:The effective rate in group C was markedly higher than those in other3groups(P
ABSTRACT
Objective To observe the alteration of scavenger receptor class A types Ⅰand Ⅱ (SR-AⅠ/Ⅱ) gene knock-out on lipid metabolism in mice fed with high-fat diet, and explore the underlying mechanism. Method The SR-AⅠ/Ⅱgene knock-out and wild-type male mice were fed with normal and high-fat diet for 12 w. Thereafter, the level of lipid metabolism (such as the levels of lipids in blood and liver) was detected with enzyme method or oil red O staining, and the expression of scavenger receptor class B typeⅠ(SR-BⅠ) and CD36 in liver was analyzed by RT-PCR. Results Under high-fat diet condition, as compared with wild-type mice, the levels of TG, TC, LDL and HDL in SR-AⅠ/Ⅱgene knock-out mice were decreased at 3, 6, 12 w (P0.05). Conclusion The alteration of lipid metabolism induced by high-fat diet in SR-AⅠ/Ⅱgene knock-out mice might be relative with the up-regulated SR-BⅠmRNA expression and the counter transport of peripheral lipids to liver.
ABSTRACT
OBJECTIVE:To discuss the necessity of clearing the pharmaceutical butyl rubber stoppers for infusion bottles before use.METHODS:Pharmaceutical butyl rubber stoppers for infusion bottles produced by manufacturer A and B were se-lected and washed at least once before a preliminary test was performed.Then product A was chosen for further test.The stoppers of two different batch numbers by manufacturer A were selected,one washed with injecting water and another not washed,all of which were used in the production of all kinds of transfusions in the hospital where the authors worked,then infusible motes in these products were measured.RESULTS:The infusible motes in the products with unwashed stoppers was not in accordance with the requirements in China Pharmacopoeia,while those with washed ones was in accordance.CONCLU_ SION:The pharmaceutical butyl rubber stoppers for infusion bottles must be washed by injecting water at least once before use to ensure the quality of the products.
ABSTRACT
AIM: To make comparative study on HPLC fingerprints of several kinds of Radix astragali from different sources. METHODS: ODS column was used,with mixture of acetonitrile and water as mobile phase in a gradient mode.The flow rate was 1.0 mL?min~(-1).The wavelength of measurement was at 203 nm. RESULTS: The fingerprints of Radix astragali were obtained. CONCLUSION: This method can be used to identify Radix astragali from different sources conveniently.
