The recombinant plasmid pPIC-gpd-bgl-hyg was constructed, which contained GPD2 promotor and terminator from industrial yeasts Saccharomyces cerevisiae, ?-glucosidase gene (BGL1) from Sac-charomycopsis fibuligera and hyg from hygromycin as the selected marker. With the yeast’s high efficiency of homologous integrated, the BGL1 gene was successfully integrated into industrial yeasts S. cerevisiae. The recombined yeast could grow on the cultures with the cellobiose as a sole carbon source, and the ?-glucosidase activity achieved 0.764 U/mL after 48 hours’ cultivation. In the experiments of VHG ethanol fermentation, the cellobiose concentration in broth of recombined yeast was 80% lower than that of indus-trial yeast.

Objective To observe the effect of exogenous basic fibroblast growth factor (bFGF) on apoptosis of cultured human retinal pigment epithelial (RPE) cells exposed to visible light,and determine the role of bFGF, fibroblast growth factor receptor 1 (FGFR1),bcl 2 and caspase 3. Methods (2000? 500) lx cold white light was used. Exogenous bFGF was utilized during culture. Annexin annexin V fluorescein isothiocyanate/propidium iodium (V FITC/PI) labeling,flow cytometry, Immunocytochemical staining, enzyme associated absorb examing and reverse transcriptional polymerase chain reaction (RT PCR) were used to determine the apoptosis, the expression levels of bFGF, FGFR1, bcl 2, as well as the activity of caspase 3. Results No protective effect of bFGF was observed under the concentration 5 ng/ml. A significant inhibition of apoptosis was found in 10 ng/ml and 20 ng/ml groups ( P5 ng/ml) groups than light exposure groups ( P

Objective To study the expression of estrogen receptor beta (ER ?) in the hypothalamic paraventricular nucleus (PVN) of maternal mice during pregnancy and lactation. Methods Nickel ammonium sulfate intensified immunocytochemical method was employed to investigate the expression of ER ? in the postnatal developing PVN of female mice. Results ER ? immunopositive materials were predominantly localized in the magnocellular division of PVN, and sparse positive cells were found in the parvocellular division. Most of the positive materials were found in the whole cell nuclei, but no obvious cytoplasma or process immunopositive cells were detected. In the pregnant female brain, generally, the ER ? level was lower. The lowest levels of expression were found at mid pregnancy, and then peaked at peripartum (from gestational days 18 to postpartum day 1), followed by another decrease to normal adult level from postpartum day 4. Conclusion The above results suggest that during pregnancy and lactation, ER ? may be predominantly involved in the PVN regulation of parturitional process.

Objective:To explore the mediating effect of loneliness on the relationship between interpersonal adaptation and mobile phone addiction in college students.Methods:Totally 368 college students (176 males and 192 females )were surveyed with the College Student Adaptability (CSAI),University of Califomiaat Los Angels (UCLA)and Mobile Phone Addiction Index (MPAI).Then AMOS18.0 was used to establish structural equation modeling (SEM)among interpersonal adaptation,loneliness and mobile phone addiction,and test the mediating effect of loneliness on the relationship between interpersonal adaptation and mobile phone addiction in college students.Results:The MPAI scores were significantly higher in the low interpersonal adaptation group (the score of CSAI less than 21 )than in the high interpersonal adaptation group (the score of CSAI higher than 32)(P<0.001).The scores of interpersonal adaptation were negatively correlated with scores of loneliness and mobilephone addiction (r =-0.71,-0.25,P﹤0.01).The scores of loneliness were positively correlated with scores ofmobile phone addiction (r =0.32,P ﹤ 0.01).College students'interpersonal adaptation did not have significantnegative predictability for mobile phone addiction (β=﹣0.08,P =0.32),but it had significant negative predictabilityfor loneliness (β=﹣0.71,P <0.001).Loneliness had significant positive predictability for mobile phone addiction(β=0.29,P <0.001).Conclusion:The results show loneliness completely plays a mediating effect betweeninterpersonal adaptation and mobile phone addiction.

Objective To study the feasibility of using the Orem self-care model in the nursing manpower management of pediatrics,and then summarized the experiences of nursing.Methods Analyzed the nursing points when using the Orem self-care model in the nursing manpower management of pediatrics,evaluated the limitation of children′s self-care,and then allocated nurses reasonable.Results The Orem self-care model was the key in the course of advance the quality of life for children,which can ameliorate the communication between the nurses and the children.Conclusion Using the Orem self-care model in the nursing manpower management of pediatrics can effective advance the nursing efficiency.

Objective To research the degree of sensory disturbance(about algaesthesis and thermesthesia) in patients with cerebral infarction(CI),diabetes mellitus(DM) and CI combined DM(CD).Methods The threshold values of rhigosis,heat sensation,cryalgesia and thermalgesia were detected by quantitative sensory testing(QST) in the patients with CI(CI group),DM(DM group),CD(CD group).Each group had 30 cases.The results were compared with normal control group(NC group).Results Compared with NC group,acral thermic sense and cryalgesia in CI group and CD group were declined obviously(all P

Objective To explore the feasibility of the application of autoregressive integrated moving average(ARIMA) model to forcast the monthly incidence rate of bacillary dysentery in Jianghan District of Wuhan ,and to provide scientific references for prevention and control .Methods SAS 9 .2 software was used to fit the ARIMA model for the monthly incidence rate of bacil‐lary dysentery from 2005 to 2013 .Thereafter ,the fitted model was used to forecast the data from January to June in 2014 ,and was evaluated by comparing the actual incidence .Results The ARIMA(0 ,1 ,1)X(0 ,1 ,1)12 model had a better fitted effect ,it was pre‐dicted that the incidence of bacillary dysentery of Jianghan District of Wuhan City from January to June 2014 would increase slight‐ly ,and the forecast data of bacillary dysentery from January 2005 to December 2013 consisted with the actual situation .Conclusion ARIM A model can be used as short‐term forecasting model to predict the monthly incidence rate of bacillary dysentery in Jianghan District of Wuhan .

Objective To investigate the significance of DNA ploidy analysis in diagnosis of atypical squamous cell of undetermined significance ( ASCUS).Methods From Jan.2009 to Jul.2011,875 women with ASCUS confirmed by liquid based thin layer cytology technique underwent DNA ploid analysis in Hubei Maternal and Child Health Hospital.Among 294 women underwent high risk HPV detection.All subjective were examined colposcopy directed biopsy at day 3 to 10 after menstruation.Results Among 875 ASCUS cases,553 cases with histologically as chronic cervicitis (63.2％),165 cases with cervical intraepithelial neoplasia (CIN) Ⅰ (18.9％ ),45 cases with CIN Ⅱ (5.1％),79 cases with CIN Ⅲ (9.0％) and 33 cases with cervical invasive cancer (3.8％) were confirmed by colposcopy.Totally 532 cases were observed with DNA heteroploid,and 343 were not observed with DNA heteroploid.When DNA heteroploid negative and more than or equal to three ploid were used to predict CIN Ⅱ or more severe cervical diseases,the sensitivity,specificity,positive predictive values and negative predictive values were 98.7％ and 90.3％,47.5％ and 46.1％,29.1％ and 40.8％,99.4％ and 92.1％,respectively.The amount of heteroploid cells ＞2.5c and ＞ 5c among every 100 detected cells in chronic cervicitis and CIN Ⅰ,CIN Ⅱ,CIN Ⅲ and cervix cancer were respectively 2.53 ± 1.99 and 0.10 ±0.07,2.24 ± 1.69 and 0.20 ±0.11,4.10 ± 1.91 and 0.28 ±0.19,7.97 ±7.33 and 1.27 ± 1.23,8.99 ±7.33 and 0.36 ±0.33,there was no statistical difference in amount of heteropolid cells between ＞ 2.5c and ＞ 5c at group of chronic cervicitis and CIN Ⅰ,CIN Ⅲ and cervix cancer (P ＞ 0.05).However,the amount of heteroploid cells at ＞2.5c and＞ 5c at group of chronic cervicitis,CINⅠ,CIN Ⅲ and cervical were higher than that of CIN Ⅱ significantly (P ＜0.05).Among 294 cases with high risk (HR) HPV detection,216 cases were HR-HPV positive,and 78 cases were HR-HPV negative.The pathology result by colposcopy at group of negative heteroploid,heteroploid ＜ 3,or ≥ 3 showed statistical distribution (x2 =115.2775,P ＜ 0.01).ConclusionDNA ploidy analysis can be used for ASCUS diagnosis,which can avoid excessive biopsy under colposcopy,in the mean time,CIN and cervical cancer could decrease missed diagnosis.
