Objective To summarize the meticulous nursing experience of indwelling urinary catheter between the children with hypospadias during perioperative. Methods 317 cases of indwelling urethral only in the silicone Foley tube, and without other urinary diversion with hypospadias were retrospectively analyzed, summarized the fine points of nursing, including preoperative children with comprehensive risk assessment, standardized preoperative skin preparation and postoperative protective constraint, effective properly fixed catheter keep the urine drainage unobstructed, close observation of urine drainage characteristics, maintain urine collection system tightness, maintain perineal skin clean and improved extubation nursing method, and do a good job after extubation nursing. Results 266 cases were cured with a cure rate of 83.9%(266/317);the incidence of urine leakage in 42 cases, the incidence rate was 13.2%(42/317); 7 cases of urethral stenosis, the incidence rate was 2.2%(7/317); 2 cases of urethral closing, the incidence was 0.6% (2/317), none of the patients had accidental extubation. Conclusions The meticulous nursing has a better effect in hypospadias patients during the perioperative period and it can reduce the incidence of postoperative complications;shorten the time of hospitalization and alleviate the suffering of children;improve the quality of nursing service, which is worthy of clinical application.

Objective To observe the effect of visible light on apoptosis of cultured human retinal pigment epithelium (RPE) cells. Methods Being the light source,500lx,(2 000?500)lx and (3 400?200)lx cold white light were used. The duration of exposure was 0,6,12 and 24 hours respectively. Apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labelling, Annexin V flunorescein isothiocyanate/Propidium iodium labelling and flow cytometry. Results Apoptosis and necrosis were found in cultured human RPE cells which were exposed to visible light.(1)A significant increase in apoptotic and necrotic percentages was consistent with a higher light intensity.(2)Apoptosis was the main response to shorter (6 h and 12 h) exposure duration,while necrosis was more pronounced correlated to the prolongation of post exposure culture ( P 500 lx) increases the proportion of apoptosis and necrosis of human RPE cells in vitro.The extent is related to exposure intensity and duration. It demonstrates that the lower intensity and the shorter duration of exposure to light are, the more pronounced apoptotic percentages are observed,otherwise necrosis.

Objective To evaluate the effect of various kinds of dyslipidaemia on insulin resistance and pancreatic islet ? cell function in newly diagnosed type 2 diabetic patients. Methods 263 patients with newly diagnosed type 2 diabetes were divided into normal lipidemia group and dyslipidaemia group according to ATPⅢ standard. The dyslipidaemia group included 3 subgroups as the following: high TG group, high TC group, and mix group with high TG and TC. Homeostasis model assessment (HOMA) was applied to estimate insulin resistance (IR) and pancreatic islet ? cell function. Early insulin secretion index (EISI) and area under curve of insulin (AUCI) at all OGTT time points were calculated. Results Incidence of dyslipidaemia in the type 2 diabetic patients was 63%. BMI and WHR were significantly higher in both high TG group and mix group than in normal lipidemia group(P

Objective:To observe the clinical effect of acupuncture combined with tuina manipulation for thoracic facet joint disorder. Methods:A total of 93 eligible cases were randomly allocated into an observation group and a control group. Patients in the observation group (n=46) were treated with acupuncture combined with tuina manipulation, whereas patients in the control group (n=47) were treated with tuina manipulation alone. The treatment was done once a day, for a total of 3 times. Therapeutic efficacies were then evaluated according to scores on signs and symptoms.
Results:After treatment, there were intra-group statistically significant differences in scores of eight signs and symptoms (all P<0.01); and the between-group differences were statistically significant in scores of eight signs and symptoms (all P<0.05). After three times of treatment, the recovery rate in the observation group was 54.4%, versus 25.4% in the control group, showing a statistical significance (P<0.05).
Conclusion:Acupuncture combined with tuina manipulation can obtain better effects than tuina manipulation alone for thoracic facet joint disorder and is therefore worth further clinical application.

Objective To investigate the factors of hospitalization expense in patients with type 2 diabetes mellitus undergoing non-emergency surgery.Methods A retrospective study included diabetic (109 cases) and control (162 cases) groups.Hospitalization expense and other observation indices were compared between two groups and subgroups.The factors that contribute to hospitalization expense were analyzed with multifactor regression analysis model.Results The median hospitalization expense was 12 014.74 yuan in the diabetic group,1.24 times than that in the control group (P =0.001).Diabetic group has higher American Society of Anesthesiologists (ASA) classification,longer wound healing time,higher postoperative infection rate,and longer hospital stay (P ＜ 0.01).Multifactor analysis revealed that the significant factors that influence the hospitalization expense were ASA classification (β =0.442,P =0.000),postoperative fasting plasma glucose (β =0.204,P =0.020),and postoperative infection (β =0.204,P =0.019).No significant difference was found in postoperative infection rate and hospitalization expense between two groups,when patients had received minimally invasive surgeries (P ＞ 0.05).Conclusions Type 2 diabetes patients have higher hospitalization expense;ASA classification,postoperative fasting plasma glucose,and postoperative infection are the main influence factors.Giving priority to minimally invasive surgeries and enhancing perioperative glucose control can help to reduce hospitalization expense in patients with type 2 diabetes mellitus.

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 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
