In this study, three methods for identification of E.coli were compared. The conventional method was employed to select and identify the suspicious E.coli isolates from a fecal sample. PCR based ARDRA analysis was then carried out to distinguish these E.coli isolates, E.coli MG1655 and other bacterial species. All the potential E.coli isolates and E.coli MG1655 had the identical ARDRA banding pattern while the other bacterial species showed the different patterns.The result indicated that the ARDRA analysis was consistent with the traditional method for identification of E.coli and could be the practical method for distinguishing E.coli from other intestinal bacterial species. The ERIC-PCR analysis provided abundant polymorphism between different E.coli isolates, and might be a powerful approach for elucidating the genetic diversity among isolates of the same species.

Producing cellulase conditions such as different temperature,inoculum size,liquid level and pH level by Trichoderma aureoviride in the shaking bottle were studied by orthogonal design method. The results showed that the main factor affecting the producing cellulase was temperature among the orthogonal conditions.The optimum conditions were as follows:cultivating solution initial pH was 6, cultivating temperature was 28℃,inoculation size was 8%,liquid level was 40 mL in 150 mL triangle bottle,rotation speed was 170 r/min.

Objective To establish a set of scientific and quantifiable performance management standard system by using Balance score card rationale so as to supply effective results management base for nursing regulator. Methods Delphi method was used to screen each level of nursing evaluation of performance standard and confirmed its weight;meanwhile, the sort of nursing care unite and nursing load were counted accordance with work intensity, risk degree and technological complexity etc and initially built performance management standard system. Results Accordance with the balance score card rationale and internal process, finance, customer, learning and growth four dimensions, a set of performance management standard and was established, including 4 first class indicator, 10 second class indicator and 32 third class indicator were derivative. The internal process, finance, customer, learning and growth factors were 29.44%, 37.56%, 20.32%, and 12.68%respectively. Conclusions Performance management standard system covers objectives of nursing management of Grade three General Hospital, and which is full of an objective, scientific, operational system possibilities, and can be used to multi-angle evaluate nursing performance, dynamic implement nurses management and achieve strategic goals.

Fermentation for Eicosapentaenoic Acid(EPA) production by Nitzschia laevis at various temperature between 10℃ and 30℃ was investigated and the dynamics characteristics during fermentation process were also analyzed.Based on the results,a varying temperature nursing method of two stage control strategy is proposed:During the first stage,which comprises the delay phase and the initial index phase,the temperature is maintained at 25℃;then the temperature is shifted to 20℃ and kept up till the end of the fermentation process.By this method,a EPA content of 6.0% and a yield of 291.60 mg/L have been gained.These are 24.07% and 18.81% higher than that of fixed temperature(25℃) fermentation,respectively.

Objective To investigate the relationship between serum adiponectin and metabolic syndrome(MS) in children and adolescents with obesity and nonalcoholic fatty liver disease(NAFLD).Methods Four elementary schools and 4 middle schools were selected from Haidian district in Beijing with representative cluster sampling.Two hundred and eighty obese children(obese group),65 obese children with NAFLD(NAFLD group) and 264 normal weight children(healthy control group) aged 7 to 18 years were recruited from the 8 schools with uncompletely randomized sampling.Data including questionnaire,anthropometric measurements,B type ultrasonographic examination for liver were collected and fasting blood laboratory assay were determined.Variables including triglyceride(TG),adiponectin,alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were skewed distribution and natural logarithmical transformations were performed.Chi-square test for category and multiple binary Logistic regression analysis were used to statistical analysis.Results Body mass index(BMI) and waist circumference(WC) in obese group and NAFLD group were higher than those in healthy control group.All the chi-square tests for trend among the 3 groups were statistically significant(P

Objective To investigate the pathogen distribution and susceptibility profile of fungal isolates from bloodstream infections,and valuate the clinical utility of G test in diagnosis of fungal infections for the purpose to improve antifungal therapy.Methods A retrospective analysis was carried out to analyze the fungal pathogens isolated from bloodstream infections in the First Affiliated Hospital of Nanjing Medical University during the period from January 2013 through December 2015 and their antimicrobial susceptibility.Results A total of 114 fungal strains were isolated from bloodstream infections during the 3-year period,most of which were Candida (99/114,86.8％),especially Candida albicans (30.7％).About 41.2％ (47/114) of the fungal strains were isolated from Department of Thoracic Surgery (10,5 and 4 strains in 2013,2014 and 2015),Hematology (11 strains in 2014),and ICU (7 strains in 2014).Antimicrobial susceptibility testing showed that all the fungal strains (100％) were susceptible to amphotericin B,but 83.5％ susceptible to itraconazole (the lowest).G test was positive before the result of blood culture in 13 of the 54 patients who received G test.Conclusions Candida was the most common fungus in fungal bloodstream infection.Amphotericin B is the most active antifungal agent in vitro.Blood culture combined with serological test can provide clinicians an earlier and reliable diagnosis.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.
