Objective To investigate the different concentrations of progesterone on the expression of a disintegrin and metalloprotease 10 (ADAM10),long form leptin receptor (Ob-R) and the secretion of soluble leptin receptor (SLR),leptin (LEP) in primary pregnancy human chorionic trophoblast cells. Methods Cultured primary human trophoblast cells and added in different concentrations of progesterone (0,100,150 and 200 ng/mL) for 24 hours. The relative expression of ADAM10 and Ob-R in the cells and the content of SLR and LEP in the supernatant were detected. Results With increasing concentrations of progesterone,early human trophoblast cells ADAM10 content gradual-ly decreased,the difference between the two groups was significant (P<0. 05). With increasing concentrations of progesterone,human chori-onic trophoblast cells in early pregnancy Ob-R expression levels increased, the difference was no statistically significant between each two groups (P>0. 05). SLR content of the cell supernatants as the concentration of progesterone increased and decreased,there are significant differences between each two groups (P>0. 05). LEP cell supernatant in each group with the increase of the concentration of progesterone concentration increased gradually between the two groups were significantly different(P>0. 05). Pearson’s test showed that the expression of expression SLR and LEP exists a significant negative correlation (R= -0. 949,P<0. 01). Conclusion Progesterone may influence the ex-pression of ADAM10,SLR and LEP by the regulation of leptin to participate GDM occurs.

Objective To develop a curriculum of a training course for oncology nurses in regard to patient education in sexuality for breast cancer patients. Methods Delphi Method was used in the study. Two rounds of questionnaire investigation were conducted among 21 specialists in breast nursing care, sexology, and psychology. The curriculum was developed after revised based on the comments and suggestions brought up in the experts. Results The training curriculum in sexual health of the breast cancer patients for oncology nurse consisted of 5 sections, professional education, sexology, medicine, psychology and practice, which were divided into 45 teaching topics included in 13 courses. The comments of the specialists on the training curriculum were consistent. The coefficients of variation ranged from 0.07 to 0.20. The coordination coefficient was 0.344. Conclusions The current study developed an integral curriculum for oncology nurses in regard to patient education in sexuality for breast cancer patients, which will benefit oncology nurses for their nursing practice.

Pharmacology can be defined as the study of sub-stances that interact with living systems through chemical proces-ses. Pharmacology plays an important role to bridge the transla-tional gap between the basic medicine and clinical medicine. In this article, the projects in pharmacology funded by NSFC during 2004~2013 were reviewed. The new features and new problems in the projects of pharmacology were briefly analyzed.

Objective To investigate the effects of epidermal growth factor (EGF) on the proliferation , migration and apoptosis of adipose-derived stem cells (ADSCs) in vitro. Methods Starved cell model and FasL-induced apoptosis model were established in serum-free media. The effects of 10 nmol/L and 100 nmol/L of EGF on the proliferation, migration and apoptosis of ADSCs in vitro were observed. The exrpessions of signal pathway proteins like phospholipaseC-γ(PLC-γ) , extracellular regulated kinase (ERK) and AKT were also detected. Results The proliferation, migration and anti-ap-optosis of ADSCs were promoted by 10 nmol/L or 100 nmol/L of EGF, and the expressions of PLC-'y, ERK and AKT were up-regulated. Conclusion EGF can promote the proliferation, migration and an-ti-apoptosis of adipose-derived ADSCs in vitro.

Aim To evaluate the effects of pantoprazole on various experimental acute ulcer inrats and mice. Methods The model of a gastric ulcer of rats or mice was caused bystree- induced ulcer and ligatel pylurus-induced ulcer. Results & Conclusions At adose of 5, 10, 20 mg? kg-1 of Pantoprazole can markedly decrease the ulcer index ofstree-induced ulcer. Pantoprazole(4, 8, 16 mg? kg -1 ) significantly decrease the areaof ligated pylorus-induced gastric ulcer. It was also found that pantoprazole caninhibit the output of basic gastric acid.

Objective To analyze the expression of dystrophin associated glycoprotein complex (DGC) in Duchnne muscular dystrophy (DMD) in different age groups. Methods The confirmed 24 DMD patients were divided into 3 groups according to their chronological age (children whose age between 1 to 3 were assigned to early childhood group; children whose age between 3 to 6 were assigned to preschool group; children whose age between 6 to 13 were assigned to school-age group). Several proteins from sarcolemmal muscle membrane were analyzed by immunohistocbemistry. Results The primary loss of dystrophin may lead to a secondary or completely deficiency of α-SG, β-SG, γ-SG,δ-SG, β-DG and dysferlin from sarcolemmal muscle membrane in different age groups. The expression of nNOS is completely deficient in the 3 groups, while the expression of caveolin-3 increased. Conclusions The expression of dystrophin related DGC proteins from DMD patients in different age groups showed diversed degrees of deficiency or complete deficiency. The deficiency of these proteins may occur during the embryonic period, while the increased expression of eaveolin-3 may have a relation with the regeneration of skeletal muscle fibers.

Objective:To investigate the inhibition of Streptococcus oligofermentans(So)on Streptococcus mutans(Sm)and the hydro-gen peroxide(H2 O2 )producibility by So under different sucrose concentration environment.Methods:The inhibition of So on Sm was observed by plating method under different sucrose concentration environment.The initial synthesis rates and production of H2 O2 by So were determined by 4-aminoantipyine-horseradish peroxidase method.Results:Under 500 mmol/L of H2 O2 ,the inhibition of So on Sm was not observed.Under the other sucrose concentration environment,the inhibition of So on Sm was as following:50 mmol/L >0 mmol/L and 1 mmol/L(P <0.05);the initial synthesis rates of H2 O2 by So under different sucrose concentrations were as following:50 mmol/L >0 mmol/L and 1 mmol/L >500 mmol/L(P <0.05);the total production of H2 O2 by So:0 mmol/L and 1 mmol/L >50 mmol/L >500 mmol/L(P <0.05).When So was inoculated before Sm,the inhibition of So on Sm was stronger than that when the two species were inoculated at the same time.Conclusion:The capability of the inhibition of So on Sm and the production of H2 O2 by So are influenced by sucrose concentration.

ObjectiveTo investigate the value of a digital three-dimensional reconstruction technique in the treatment of hepatic alveolar echinococcosis (HAE).MethodsThe computed tomography scan data for 13 patients with HAE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from February 2011 to October 2011 were reconstructed and analyzed by a three-dimensional reconstruction system to assess resectability,and to facilitate surgical planning and individualized virtual surgery.The results of preoperative analysis were compared with the results of actual operations.ResultsThe three-dimensional models of the liver were reconstructed successfully,and intrahepatie lesions and vessels were clearly displayed.One patient received an autologous liver transplantation,10 underwent hepatectomy,and 2 received percutaneous transhepatic cholangial drainage.Virtual operation planning was carried out for 11 patients using the three-dimensional reconstruction system.The mean volume of the liver to be resected was predicted to be 920 ml (range,339-2678 ml),and the mean percentage of liver to be resected to the total liver volume was predicted to be 45％ ( range,23％ -68％ ).The mean volume o[ the actual liver resection was 834 ml (range,315-2250 m[),and the mean percentage of actual liver resected to the total liver volume was 42％ (range,22％ -70％ ),which was consistent with the results of preoperative three-dimensional reconstruction.All patients were followed up for 2-8 months,and no severe complications such as liver failure,hemorrhage and bile leakage were detected.ConclusionDigital three-dimen-sional reconstruction is helpful in the diagnosis and treatment of HAE and effectively reduces surgical risks.
