The association between psychogenic illness and human endogenous viruses (HEVs), including human endogenous retrovirus and Borna disease virus, remains unclear. As the component of human genome, HEVs may become the joint of various pathogenic factors of schizophrenia (SZ), such as heredity, environment, and immunity. In this review, we strive to uncover the clinical and laboratory evidence for the roles and possible pathogenic mechanism of HEVs in the development of SZ.

The determination and characterization of solid drug form polymorphisms plays an important role in drug quality control, selection of the production process and clinical efficacy evaluation. Vibrational spectroscopy is a powerful method for the characterization of drug polymorphisms. In this paper we review recent research and application advances in the polymorphic characterization of active pharmaceutical ingredients (APIs) and drug cocrystals/salts by using Fourier transform infrared (FTIR) and Raman spectroscopy to elucidate the characteristics of APIs and drug complexes. This may provide theoretical support for structural analysis during the development process for drugs.

Objective: To investigate the effect of PKG II (cGMP-dependent protein kinase II) on cell proliferation-related MAPK (mitogen-activated protein kinase)/ERK (extracellular signal-regulated kinase) downstream targets RSK1 (ribosomal S6 kinase 1) and proto-oncogenes c -Jun and c -Fos in gastric cancer SGC-7901 cells. Methods: Gastric cancer SGC-7901 cells were infected with Ad-LacZ and Ad- PKG II adenovirus, and then the PKG II was overexpressed in SGC-7901 cells. These cells were treated with PKG II specific activator - 8-pCPT-cGMP [8-(p-chlorophenylthio)-cyclic GMP], and then they were stimulated with EGF (epidermal growth factor). The proliferation of SGC-7901 cells was examined by MTT method, and the mRNAs expression levels of c-Jun and c-Fos and the protein expression levels of p-RSK1, c-Jun and c-Fos were examined by RT-PCR and Western blotting, respectively. The nuclear accumulation of p-RSK1 was observed under an immunofluorescence microscope. Results: EGF-induced increase of cell proliferation and the elevation of expressions of c-Jun and c-Fos mRNAs and proteins as well as p-RSK1 (Ser380-) protein in SGC-7901 cells which were infected with PKG II were significantly inhibited after treatment with 8-pCPT-cGMP. The phosphorylation of RSK1 (Ser380) was decreased, and the accumulation of p-RSK1 (Ser380) in nuclei of SGC-7901 cells was increased after stimulation with EGF, while it was decreased after treatment with 8-pCPT-cGMP. Conclusion: Activated PKG II can inhibits the proliferation of gastric cancer cells, phosphorylation of RSK1 (Ser380), nuclear accumulation of p-RSK1(Ser380) and the expressions of c -Jun and c -Fos genes which were induced by EGF.

Objective To investigate the plasma visfatin levels and explore the relationship between visfatin and anthropometric parameters,glucose,lipid profile,insulin sensitivity index and insulin secretion index in the subjects with different glucose tolerances.Methods Fifty-three patients with newly diagonosed type 2 diabetes(T2DM),7 subjects with impaired glucose tolerance(IGT)and 35 healthy controls were enrolled.Visfatin levels were measured along with the BMI,blood pressure,lipids,glucose,insulin and HOMA-IR indexes.Results Plasma visfatin levels were elevated in patients with newly diagnosed T2DM compared with IGT group or controls.There was no significant difference in the visfatin levels between IGT group and healthy controls.Plasma visfatin level was positively correlated with glucose levels and HOMA-IR,and negatively correlated with insulin secretion index(HOMA-B).Multiple regression analysis showed that postprandial plasma glucose was independent related factor influencing plasma visfatin levels.In T2DM group,plasma visfatin concentration was positively correlated with HbA1c level.Conclusion The increased plasma visfatin concentration in newly diagnosed and untreated type 2 diabetes mellitus represents a compensatory mechanism aimed at ameliorating the functional consequences of insulin deficiency.

This article is based on the searching from the United States Library of Congress Web Search science 2005 for the literature on the birth femoral fractures,reviewing its incidence,pathogenesis and treatment of such fractures of the latest developments,for the purpose of the provision of orthopedic and obstetric physician reference.Literature showed that neonatal birth femoral fractures might occur whether deli-veries were through the birth canal or by cesarean section.Whenever faced with fetal asphyxia,intracranial hemorrhage,such as critical state,it is critical to save the life of fetal babies,regardless of treatment.The prognosis of neonatal femoral shaft fractures is normally good without deformity left.

Objective: To explore the effect of case introduction and assessment approach of the team in strengthening the skills training of school nursing students. Methods:Selected 289 undergraduate nursing students from grade 2010 as experimental group, 281 students from grade 2010 as control group, the experimental group adopted case introduction and assessment approach of the team, the latter used the traditional assessment method, after the end of the training, two groups of students were operating examination and questionnaire survey. Results:The nursing students in the experimental group of operating examination results was better than the control group(P<0.05).The application of case introduction and assessment approach of the team can develop good teamwork spirit(86.30%), communication skills(71.85%), consciousness of active learning(81.11%), clinical decision-making(75.93%), and clinical adaptive-ability(87.04%). Conclusion:The model of case introduction and assessment approach of the team can improve the clinical comprehensive ability partly.
