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.

Characters of one Candida intermedia yeast strain which isolated from nature can produce ethanol from xylose-fermenting been systemic studied. In conditions 28?C, 120 r/min, 72 h, it can produce 6.480 g/L ethanol from 7% xylose and 43.70% theoretical production of ethanol from 3% xylose. It can produce up to 21.225 g/L ethanol when incubation time prolong to 156 h from 8% xylose. It also can ferment 13% glucose produce 47.647 g/L ethanol and reach 76.90% of theoretical ethanol production, respectively. Compared to CK, ethanol productivity can be improved 9.91% when add 8% xylose in three times as 3%, 2% and 3%, respectively. Glucose can be first utilized in the mixture sugar medium. When the ratio of xylose vs. glucose is 3:1in mixture sugar, the productivity of ethanol can be improving 25%.

Objective To upregulate Notch signaling in cancer cells by overexpression of active part of Notch1 and to examine the proliferation of the cells. Methods Four cancer cell lines were infected with retrovirus recombined with sequence encoding active part of Notch1.CBF-1 reporter plasmid was used to detect Notch signaling and proliferation assay was carried out by MTS method.Cell cycle analysis was synchronously conducted. Results The overexpression of the active part of Notch1 induced upregulation of Notch signaling,led to growth inhibition in Hela and HepG2 cell lines and growth boost in BGC-823 cell lines,while had no effect on Chang cell lines. Conclusion The upregulation of Notch signaling can exert various effects on different cancer cell lines which is critical to the gene therapy for cancers.

Objective To investigate the detection results of GHB with different instruments, and to provide reliable basis for improving the accuracy of GHB detection. Methods ADVIA 1650 biochemical analyzer and HA-8160 glycosylated hemoglobin analyzer were used. The accurate detection of glycosylated hemoglobin in 100 healthy people was carried out, and the related data were recorded and analyzed statistically. Attention should be paid to this group according to glycosylated hemoglobin detection value, that is, within 6.5％ for A group, 6.5％-10.0％ for B group, more than 10％ for C group, and compare the above-mentioned different grouping of corresponding instrument glycosylated hemoglobin detection value. Results The analysis showed that there was no significant difference between the two groups of C instrument glycosylated hemoglobin levels, but the level of glycosylated hemoglobin detected by A in group HA-8160 and group B was significantly higher than that of ADVIA 1650(P<0.05). Conclusion Different instruments have some differences in the detection value of glycosylated hemoglobin. Clinicians should judge the disease comprehensively according to the actual situation and other indicators.

Objective To analyze the factors related to the disqualification of urine routine and stool routine, and to formulate corresponding solutions. Methods In April 2014 to April 2017 our collected 600 cases of hospitalized patients, urine and stool samples for routine detection, made clear that cause unqualified samples related factors, and develop effective solution strategy. Results 600 cases in the selected routine urine, excrement and urine routine test specimens, the unqualified samples of total 110 cases, fraction defective is 18.33%, 490 qualified samples, percent of pass is 81.67%, the difference was statistically significant (P<0.05).There are a number of factors that cause the sample to fail, such as the contamination of the sample, the length of storage, the operation and the preparation. Conclusion In the process of actual diagnosis of disease, clinical result in urine, feces routine test specimen unqualified often appear, the reason is to a great extent, and the related nursing staff in urine and stool samples of patients before the lack of relevant guidance and so on, and nursing staff after the complete collection of specimens does not usually in accordance with the relevant standard of serious check, to avoid the sample inspection is unqualified, hospitals need to develop scientific inspection process, nurses in practice need to strict adherence to the process, and through intensive training, promote nursing staff awareness test, can to improve the qualification rate of sample test provide strong guarantee.

OBJECTIVE:To study the influence of calcineurin gene polymorphism on the efficacy of cyclosporine A (CsA). METHODS:The blood samples of patients treated with CsA were collected. The trough blood concentration of CsA was detected by EMIT. The genotype of PPP3CA and PPP3CB was assayed by RFLP-PCR method. The expression of NFAT-regulated gene IL-2, IFN-γand GM-CSF were measured by RT-qPCR,which were used to define the index of indirect efficacy of CsA. The relationship of gene polymorphism with CsA efficacy was study by relationship analysis and multiple factor regression method,etc. RESULTS:A to-tal of 100 blood samples were collected. There was no significant correlation between the expression of CsA efficacy-related NFAT-reg-ulated gene GM-CSF and trough concentration of CsA(rGM-CSF=-0.04,P=0.238);the expression of IL-2 and IFN-γ were negatively correlated with trough concentration of CsA significantly(rIL-2=-0.384 3,P<0.001;rIFN-γ=-0.335 4,P<0.001). Using the average value of mRNA expression of IL-2 and IFN-γas indirect efficacy index,the polymorphism of PPP3CB rs3763679 site significantly in-fluenced the efficacy of CsA(P<0.05),but PPP3CA rs3804358 had no any effect on it(P>0.05). Stratified analysis showed that among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 genovariation(TC+TT) were better than those with wild-type gene (CC)(P<0.05). After the efficacy was normalized by CsA trough concentration, multivariate analysis showed that normalized efficacy of CsA was negatively correlated with gender,PPP3CB rs3763679,lactate dehy-drogenase and creatinine significantly,but positively correlated with PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate,etc. CONCLUSIONS:PPP3CB rs3763679 gene polymorphism influence the efficacy of CsA;among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 TT+TC is better than that of CC type. At the same time,gender,PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate and other factors all can influence the nor-malized efficacy of CsA to different extent. Multiple factors should be considered when using CsA.
