e: Vancomycin is a glycopeptide antibiotic separated from streptomycete, having been used as the ifrst choice to treat methicillin-resistant Staphylococcus aureus infection so far. The studies show that because of the individual difference in the metabolism of vancomycin, it is dififcult to get the trough concentration of pediatric patients severely ill or complicatedly in-fected to reach the target range (15—20 mg/L). However, with the help of therapeutic drug monitoring (TDM) of vancomycin and the pharmacokinetic/pharmacodynamic parameter (PK/PD) mode, the PK/PD parameters to achieve the precise control can be acquired by using the Bayes feedback. By a stretched review from clinical medication guide of vancomycin to the latest evidence from research, this paper fully demonstrates that renal function, weight, age, and disease state are the principal parameters to impact pediatric patient’s vancomycin metabolism and that the area under the concentration-time curve divided by the minimum inhibitory concentration (AUC/MIC)≥400 is the better cut-off value to determine vancomycin efifcacy and toxicity.

This paper found some unsuitability of cognition,attiude and behavior when people deal with the various profit relationships in the gene treatment because of effect theory,benethamism intention and breaking the game rule.In my opinion, we must persist in the suitable ethic principle in the gene treatment.

The clinical data of 8 patients with the fourth-degree laceration of perineum, who were admitted in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2004 to December 2010, were reviewed retrospectively. The causes and clinical strategies were analyzed. The fourth-degree laceration of perineum was mainly caused by improper skills of midwifery, too faster labor,insufficient estimation of fetal-weight and perineal condition and obstetric forceps in this group of patients.Primary suture was performed and all cases achieved complete healing. The improvement of midwifery skill,carefully monitoring the uterine contraction, accurate evaluation of condition of perineum and the fetal-weight and good communication between patients and midwives are the key points to prevent the fourth-degree laceration of perineum.

This study examined the effect of resveratrol on the secretion of vascular endothelial growth factor (VEGF) and subsequent proliferation of human leukemia U937 cells, and explored the mechanisms involved. Human leukemia U937 cells were treated with resveratrol of different concentrations (12.5-200 micromol/L) for different time lengths (12-48 h). The proliferation of the U937 leukemic cells was determined by MTT assay. Apoptosis was observed by Annexin-V-FIFC/PI double staining and flow cytometry (FCM). Cells cycle was analyzed by PI staining and FCM. The content of VEGF was determined by ELISA. Human umbilical vein endothelial cells were examined for vasoformation in vitro after exposures to resveratrol of various concentrations. The results showed that resveratrol inhibited the proliferation of U937 leukemia cells in a dose-and time-dependent manner. Resveratrol induced apoptosis and S-phase cell cycle arrest in human leukemic U937 cells. Resveratrol inhibited the secretion of VEGF in U937 cells. Resveratrol inhibited the vasoformation of human vein endothelial cells in a dose-dependent manner. It was concluded that resveratrol could down-regulate the secretion of VEGF, induce apoptosis and suppress the proliferation of U937 cells.

Objective To observe effect mechanism of L-arginine (L-arg,a precurory substance of nitric oxide sythesis) in proveting proteinuria in adriamycin-induced nephrosis model of rats.Methods Nephrosis model of 16 rats was established by tail vein injetion with adriamycin,then the 16 rats were divided into two groups;model group and treatment group with L-arg administration (treated group),the levels of nitric oxide(NO),endothelin-1(ET-1),renal function,and pathological changes were observed in the two groups.Results The successful nephrosis model of rats was indentified with optical and electron microscope technique.Proteinuria was occurred in the two groups,but proteinuria degree in treated group was lighter than those of model group,however NO level was higher than that of model group,there was negatively correlation in the levels of NO and ET-1 between both groups,pathological alteration under electron microscope observation was obviously less in the treatment group than those of the model group.Conclusions On basis of these findings,author consider that the L-arg could reduce proteinuria output by promoting NO synthesis and suppress the ET-1 production.

Enzyme-linked immunosorbent assay for determination of thyroid-stimulating antibody in the sera of patients with Graves' disease was established using ganglioside (GLS) purified from bovine brain as binder. It was applied in clinical practice. The results showed that LATS could react with ganglioside under suitable conditions. Very significant difference was observed between normal subjects and untreated GD (P

Objective:To develop and apply a method for real-time quantifying IL-6 mRNA.Methods:By Ficoll-Hypaque density gradient centrifugation, human peripheral blood mononuclear cells(PBMC) were isolated from whole blood treated with ethylenediaminetetraacetic acid(EDTA). Total RNA extracted from the PBMC in trizol solution was reverse transcribed to cDNA, which used as templates for fluorecent real-time quantitative PCR amplification of IL-6. PCR system consists of IL-6 primer, SBY Green Ⅰ and so on.Results:The method is wide linear range, sensitive, specific, reproducible and simple.Conclusion:The method can accurately quantify IL-6 mRNA.

Objective To investigate the risk factors of insulin resistance(IR)and its relationship with metabolic syndrome in patients after lenal transplantation.Methods 133 renal transplant redpients who had not undergone acute rejection,calcinurine intoxication and severe infection,and had normal renal function and no proteinuria at the 6th month post-transplantation,were involved in the study.They had a history of chronic glomerulonephritis as the primary disease of ESRF but rio diabetes mellitus.108 recipients(CsA group)were treated with CsA,mycophenolate mofetil(MMF)and prednisone after transplantation,19 recipients(Tac group)with tacrolimns(Tac),MMF and prednimne,and 6 recipients with Simlimus,respectively.One year later,blood and urine biochemical tests and physical examinations were performed on the recipients,and HOMA calculated.200 cormnunity residents were randomly selected as controls.Results The incidence of MS in the recipients was 33.1%,significantly higher than controls(15.0%).There was no significant difference in the incidence of obesity and overweight between recipients(29.3%)and controls(37.5%).In recipients with obesity or overweight,the insulin-resistance level and urine albumin level,and the incidence of MS weree significantly higher than those without obesity or overweight.The insulin-resistance level in Tac-treated recipients was markedly higher than CsA-treated recipients,and there was a positive correlation between the blood concentration of Tac and insulin-resistance levd.Microalbuminufia-positive recipients had higher insulin-resistance levels.Metabolic syndrome-complicating recipients had higher insulin-resistance levels than those without metabolic synawme,and higher insulinresistance levels existed in recipients with hypertriglyceridemia or hyperchcllesterolemia,hypertension.Conclusion Obesity or overweight,Tac(especially when blood concentration was higher)were risk factors resulting in imulin-resistanee in kidney transplant recipients.It is suggested that insulin-resistance might be involved in the pathogenesis of metabolic syndrome including hypertrglyceridmaia,hypercbolestemlemia and hypertenion.
