1.Pathogenic significance and possible pathogenic mechanism of human endogenous viruses in development of schizophrenia.
Chinese Journal of Virology 2014;30(1):98-102
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.

3. PKG II inhibits downstream targets of proliferation-related MAPK/ERK in gastric cancer cell line SGC-7901
Tumor 2012;32(11):862-867
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.

4.Advances in characterization of pharmaceutical polymorphisms by vibrational spectroscopy
Acta Pharmaceutica Sinica 2021;56(1):102-112
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 explore the effects of advanced glyeosylation end products (AGEs) on the binding of hepatic nuclear factors to the human insulin receptor (hlR) gene promoter. Methods The oligonueleotides with hlR gene promoter activity, 42 bp (spanning -1 441 to -1 400, US1) or 146 bp (spanning -638 to -493), were artificially synthesized, with point mutations at 5 key G residues in 42 bp US1 m5 oligonucleotides. US1 and rat hepatic nuclear extracts (HNE) were incubated with glucose 6-phosphate, prior to non-competition and competition gel retardation electrophoresis. Results Competition gel retardation electrophoresis showed that the binding capacity of 32p-labeled US1 probe to HNE could be signifficantly decreased with increased US1. US1-AGEs and US1m5 decreased the binding of probe to HNE as well, but only partly affected the electrophoretie bands [1,5,10 ng US1-AGEs: (41.08±2.86)%, (27.64±2.92)%, (15.35±1.81%) vs (52.05±1.79)%]; 5,10 ng US1m5: (5.20± 1.03)%, (1.81±0.21)% vs (52.05±1.79)%]. AGEs formed on HNE could increase the binding of HNE to probe, along with nonspecifie binding increasing. Conclusion The impact of AGEs on hlR gene expression seems to be related to the effects on cis-elements and trans-acting factors.

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.

Objective To explore the significance of ultrasound in choosing the delivery modality in 200 cases scarred uterus gravida′s second deliveries .Methods The study selected 200 cases late pregnancy gravidas who had once uterine incision delivery history and analyzed clinical data retrospectively ,all of them were chosen from September 2010 to September 2013 in our hospital . All cases were taken by transabdominal ultrasound or transvaginal ultrasound firstly ,then taken by transabdomina transvaginal ul‐trasound ,finally contrast obsenved the transabdomina transvaginal ultrasound detections with their caesarean section observations , meanwhile observe how the uterus scar ranking affect the delivery consequence .Results (1)A total of 200 cases had higher uterus scars visualization ratio(100 .0% ) than ransabdominal ultrasound (92 .0% )and transvaginal ultrasound(96 .5% )(P<0 .05);con‐trasting the transabdomina transvaginal ultrasound with the caesarean section observations ,there was no significant difference(P>0 .05) .The grading diagnosis coincidence of transabdomina‐transvaginal ultrasound was 89 .74% .(2)The UD rate ,the bleeding vol‐ume during operation and the 24 hours postoperative bleeding volume of scarred uterus gravida grade Ⅱ and grade Ⅲ were signifi‐cantly higher than grade Ⅰ (P<0 .05) .Conclusion Transabdomina transvaginal ultrasound can effectively improve the diagnosis coincidence rate of uterine scar detection and can help to chose the better delivery mode according to the scars healing .
