Objective To evaluate the efficacy of gentamicin solution in transurethral ureteroscopic lithotripsy to prevent postop- erative infection.Methods Prospective clinical randomized control study was conducted.From July 2003 to June 2006,116 ca- ses of ureteral stones at high risk of postoperative infection were randomized into control group or gentamicin group.Patients in gentamicin group received gentamicin solution for washing in the operation.All the patients undergoing operation were followed up for 2 weeks after operation.Diagnosis of postoperative infection was based on clinical manifestations.Results A total of 109 patients received operation in all the 116 cases,including 58 cases in gentamicin group and 51 cases in control group.Thirteen cases of postoperative infection were identified in all the patients receiving operation (11.93%),3 cases in gentamicin group and 10 in control group.The incidence of postoperative infection was significantly different between the two groups (X~2= 5.3342,P=0.0209).Eight cases had positive bacterial culture.Of the microbiological isolates,2 were gram-positive bacteria, 5 gram-negative bacteria and 1 Candida albicans.Conclusions The most common pathogen causing postoperative infection after transurethral ureteroscopic lithotripsy is gram-negative bacteria.The use of gentamicin solution for washing in the operation can reduce the incidence of postoperative infection.

Objective To investigate clinical characteristics of refractory systemic juvenile idiopathic arthritis(JIA)and the efficiency of glucocorticoid in therapy on this kind of disease.Methods Thirty-nine children with systemic JIA were divided into low dose group 0.5-1.0 mg/(kg?d)and high dose group 1.0-1.5 mg/(kg?d).And the efficiency was observed by change of active index after 10 and 20 days.Results The effective power was 58.8% and 72.7% after 10 days,respectively.After 20 days,the power was 76.5% and 90.9%,respectively.The power in high dose group was significantly higher than that in low dose group.It had no difference in statistical analysis for efficiency of 2 kind of glucocorticoid dosage to control fever,but it had obvious difference to control arthralgia,arthrocele,erythrocyte sedimentation rate(ESR),C-reactive protein(CRP).Conclusion Glucocorticoid therapy is very effective to control the activity of disease in patients with systemic JIA.

Objective To estalish an accurate method for determining the content of astragaloside Ⅳ in Shouqing Granula. Method TLC scanner was selected to detect astragaloside Ⅳ with silica gela thin layer. The sample was separated by using chloroform-methanol-water (13 : 6 : 2) below 10 ℃ overnight with the under layer solution, ?_s=530 nm, ?_R=700 nm. Results The linear ranges of astragaloside Ⅳ was 0.22～ 0.73 ?g, the average recovery was 97.72%, RSD=0.69%. Conclusion The method was simple and accurate, and can be used for the quality control of Shouqing Granula.

In order to study the regularity of shedding virus from infected SPF chickens and the formation of aerosol of H9N2 subtype AIV, SPF chickens were bred in a positive and negative pressure isolator. Aerosol samples were collected by AGI-30 (All Glass Impinger-30) extractor, and simultaneously trachea and cloaca samples were collected by tracheal swabs and cloacal swabs in different periods after challenged with vi- ruses. The above-mentioned samples were detected by HI, Dot-ELISA and RT-PCR methods. The results in- dicated that aerosols were isolated from the 4 days to the 43 days after inoculation. It was proved that H9N2 subtype AIV could copy themselves in respiratory passage and cloaca, and then could formation of aerosols. AIV H9N2 subtype could be isolated from cloacal and tracheal swabs 3 days after inoculation and lasted for 45 days, viruses were detected from all infected SPF chickens on 7 days.

There has been increasing interest in the psycho-socio-relational and sexual disorders of infertility, as the risk of psychological burden among infertile men with sexual dysfunctions is significant. The purpose of this study was to develop and to validate a predictive model to estimate individual psychological burden among infertile men with sexual dysfunction and study the association between them. Comprehensive data were collected for infertile men (n = 480) who sought treatment for infertility in a reproductive medicine center between June 2012 and December 2013. Using independent predictors of psychological burden from the least absolute shrinkage and selection operator, univariable and multivariable analyses were developed into two models. Predictive accuracy was compared between the models. We explored the association between sexual dysfunction and psychological burden. A total of 480 patients were analyzed using 10-fold cross-validation. Independent predictors of psychological burden were incorporated into a model to measure anxiety (corrected-area under curve (AUC): 77.3%) and a model to measure depression (corrected-AUC: 70.2%). Anxiety and depression were both associated with erectile dysfunction (P < 0.05), with anxiety demonstrating the strongest association. Only anxiety was associated with premature ejaculation (P < 0.05). Premature ejaculation was not found to be associated with depression (P > 0.05). Predictive models for psychological burden among infertile men with sexual dysfunction are presented, and we found that there is an association between psychological burden and sexual dysfunction. According to the models, proper counseling and treatment of sexual dysfunction in infertile men may reduce the psychological burden, help attain natural pregnancy, and improve the quality of life.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

OBJECTIVETo study the influence of humic acid fertilizer on plant growth, assimilation base, dried biomass accumulation, yield, quality and disease infection of Angelica sinensis.

METHODThree kinds of humic acid fertilizer and an amino acid liquid fertilizer were tested in randomized groups at 1 level with 3 times repeat.

RESULTT1 promoted plant and root growth effectively, increased dried biomass accumulation and fresh root average weight remarkably, the yield was increased, the content of ethanol extract was increased by 11.31%. T3 promoted plant and root growth quickly, enlarged leaves area and increased dried plant weight, but effect lasted shortly, the content of ethanol extract was increased by 5.23%. T4 increased more leaves in late growth period, enlarged leaves area, the yield was increased, the content of ethanol extract was increased by 3.09%. T2 increased fresh root average weight remarkably, the yield was increased.

CONCLUSIONHumic acid fertilizer and amino acid liquid fertilizer could effectively promote plant growth, enlarge leaves area, promote dried biomass accumulation and transformation to root and increase yield and content of ethanol extract effectively.

A temperature-sensitive mutant strain was isolated after transposon mutagenesis with Tn5 and named MT54.PCR was carried out with primers designed according to the sequence of transposon,the PCR products showed that the MT54 carried transposon in the genome. The mutant grew well at 30℃in minimal medium(MM)containing p-nitrophenol(PNP)as sole carbon source,while it cannot grow at 37℃in the same medium,NO_2.detection results also proved that.Comparing the degradation rate of PNP and hydroquinone of MT54 and DLL-E4 at different temperature,it was speculated that the mutant site locate in the PNP degradation related genes.
