Objective To investigate the expression of aquaporin-1 (AQP1) in human peritoneum and its effect on peritoneal dialysis (PD) patients with the different peritoneal transport characteristics.Methods Peritoneal biopsies were obtained from the PD patients (n =30) at catheter insertion.Western blot and immunohistochemical staining were used to investigate AQP1 expression in peritoneal tissues.After catheter insertion,4 week,peritoneal equilibrium test (PET) was used to decide peritoneal transport characteristics.Results Western blot revealed a major band at 28 kDa band.The expression of AQP1 index was 1.49 ±0.67 in the normal subjects,and 1.61 ±0.76 in the PD patients,and there was no significant difference.Positive deposition was distributed in mesothelial cells,endothelial cells of capillaries,and small veins.The index of AQP1 expression in endothelial cells of capillaries in normal subjects and PD patients were 2.12 ±0.18,and 2.50 ±0.81,respectively,and no significant difference was found.The index of AQP1 expression in mesothelial cells of capillaries in normal subjects and PD patients were 1.95 ± 0.67,and 2.23 ± 1.07,respectively,and no significant difference was found.Among PD patients,the level of AQP1 was significantly different.Conclusions The expression of AQP1 was different in the PD patients with different peritoneal transport characteristics.In the high and high average transport groups,the level of AQP1 was lower; the low transport group was higher.It reveals that AQP1 plays a role in the pathogenesis of transcellular water transport.

Multidetector computed tomography (CT) has transformed CT from an transaxial cross-sectional technique into a genuine 3D imaging that allows for arbitrary cut planes as well as excellent 3D displays of the volume data. Multidetector CT scanners contribute to reduced scanner time, decreased section collimation and increased scan length.

Objective To obtain the endophytic fungi which produce Huperzine A from four species in Hupziaceae and improve the culture conditions of screening endophytic fungi. Methods Plant materials were cultivated in culture medium after sterilization and their endophytic fungi were isolated. Hupzine A from metabolic was determined by HPLC, and the strains were identified by microscopic features. Results Thirty-two endophytic fungi were isolated from Huperzia serrata (Thunb. ex Murray) Trev, H. serrata (Thunb. ex Murray) Trev var. longipetiolata (Spring) H. M. Chang, H. appressa (Desv.) Love et D. Love, Phlegmariurus cryptomerianus (Maxim.) Ching ex L. B. Zhang et H. S. Kung. Two of these strains were isolated from P. cryptomerianus, HA15 (Blastomyces sp.) and HA23 (Botrytis sp.), which produced Huperzine A. Conclusions Endophytic fungi producing Hupzine A has been successfully isolated from P. cryptomerianus.

PURPOSE: This study was done to examine perioperative nurses' perception of the definitions and causes of nursing errors; the relationships among emotional distress, coping strategies, and changes in practice as a result of errors. METHODS: A descriptive, correlative design was used with a sample of 146 nurses working in the operating room of a university hospital. Data were collected using a self-report questionnaire with 4 point Likert scales. For the analysis, t-test, ANOVA, Scheffe's post hoc test and multiple regression analysis were used. RESULTS: Most nurses recognized themajority of the items as perioperative nursing errors. Job overload was perceived as the cause of errors. Emotional distress was significantly related with nurses' age, position and years of work experience. The coping strategies used most frequently were 'accepting responsibility' and 'planful problem solving'. The coping strategies of 'accepting responsibility', 'planful problem solving', 'seeking social support', and 'using self-control' were significant predictors in constructive practice change. Defensive changes were related to the strategy of escape/avoidance and emotional distress. CONCLUSION: The results of this study suggest that intervention strategies should be developed to decrease perioperative nurses'distress and improve their coping strategies resulting in constructive change in practice after committing an error.

PURPOSE: This study is to identify the factors that affect middle-aged workers' health promoting behaviors. METHODS: 214 middle-aged workers participated in surveys, and the data were collected from August to September 2012 and analyzed by using descriptive statistics, Pearson's correlation coefficient, and multiple regression analysis with PASW 18.0 program. RESULTS: It was found that among the factors, the degree of job stress (t=7.69, p<.001) and depression (t=6.23, p<.001) were significantly high for type D individuals, while non type D showed meaningful degree of self-related health status (t=-3.66, p<.001) and health promoting behaviors (t=-4.71, p<.001). The notable variable that affected the health promoting behaviors of the middle-aged workers was depression for both type D (beta=-.357, p= .029) and non type D (beta=-.325, p<.001) individuals, and this variable accounted for 24.1% and 18.2% respectively. CONCLUSION: The study revealed that the middle-aged workers showed high degree of job stress and depression that influenced on their health promoting behaviors. Thus, they are recommended to receive health management programs that offer treatment through consulting considering their individual personalities.

Objective: This present study is to establish a rat model of intravenous heroin self-administration and observe the effect of electro-acupuncture on the heroin-seeking behavior of the heroin self-administrating rat. Methods: Six Male Wistar rats were surgically implanted with an intra-jugular intravenous catheters under sodium pentobarbital anesthesia,following a minimum recovery of 7 days, the rats were trained by nose-poke response with one daily 4-hour session for 14 consecutive days to self administer heroin (50 μg /kg / per injection), the session ended after 25 infusions were earned or 4 hours had passed, whichever came first, the reinforcement schedule was fixed ratio 1 (FR1) that the rat received a heroin injection for each nose poke response. And then the rats were given electro-acupuncture treatment daily 30min prior to each session and then were trained with one daily 4-h session for 7 consecutive days. Results: Stable intravenous heroin self-administration behavior of rats was established after 7-8 days' drug training, electro-acupuncture given to the stable heroin self-administrating rat 30 min prior to each session could reduce the drug self-administration behavior, namely the total heroin intake in each session was reduced, especially the 1st hour heroin intake, the initiation of first nose-poke response in each session was relayed, and the haste heroin-seeking behavior also became slower. Conclusions: The above results suggested that the electro-acupuncture had better detoxification effect.

Objective To examine the preventive effect of magnesium sulfate on hypertension caused by ACTH in the treatment of infantile spasms (IS). Methods 46 children diagnosed as IS were recruited from two hospitals during May, 2011 to October, 2013.23 patients in group A (treatment group) were treated with magnesium sulfate and ACTH in hospital A;another 23 cases in group B (control group) were treated with ACTH only in hospital B. The therapy course was 2 weeks. Results Hyperten-sion was not observed in the treatment group, while 6 children were observed with hypertension in the control group. There was signiifcant difference between the two groups (P<0.05). Conclusions Magnesium sulfate could prevent the incidence of hyper-tension in the treatment of IS with ACTH, and beneift the completion of treatment course.
