OBJECTIVEJianyate Hao (JYTH) , a traditional Chinese medicine formula, which has been used effectively to treat depression in the past ten years. The purpose of this study was to explore the antidepressant effect of acute administration with JYTH and its possible mechanism.

METHODthe animals behavioral despair models of depression, the tail suspension and forced swimming tests, were used to explore the antidepressant effects of JYTH. In addition, the locomotor activity test was used to detect the change of locomotor activity. The monoamine oxidase activity in the mouse brain was also determined by using fluorospectrophotometry.

RESULTJYTH (17.5, 35, 70 g x kg(-1), ig) could decrease the duration of immobility in both tail suspension and forced swimming tests, and the effect of JYTH (35 g x kg(-1) ig) was resembling imipramine (10 mg x kg(-1), ip) in relieving depression. And the effective doses (17.5, 35, 70 g x kg(-1), ig) did not alter locomotion activity. Moreover, JYTH (35 g x kg(-1), ig) was found to inhibit monoamine oxidase activity in the mouse brain.

CONCLUSIONThese findings suggest that JYTH exerts antidepressant effect in animals behavioral despair tests and the underlying mechamism may involve the inhibition monoamine oxidase activity in the mouse brain.

Objective To investigate the clinical effect of Compound Danshen Dripping Pill (CDCP) combined with polyene phosphatidyl choline in the treatment of nonalcoholic fatty liver disease.Methods Patients with nonalcoholic fatty liver disease (116 cases) treated in Xi'an Medical University Affiliated Baoji Hospital from January 2012 to December 2015 were selected and divided into two groups randomly.Control group was treated with CDDP,and observation group was treated with CDDP combined with polyene phosphatidyl choline,the two groups were treated for 3 months.The clinical efficiency of two groups was compared.The following indicators were detected before and after treatment respectively,such as liver function indicators:aspartate aminotransferase (AST),alanine aminotransferase (ALT),γ-glutamyltransferase (γ-GT) and total bile acid (TBIL);blood lipid indicators:total cholesterol (TC),triacylglycerol (TG);and liver triglyceride fibrosis indicators:laminin (LN),hyaluronic acid (HA),procollagen Ⅲ (PC Ⅲ),and type Ⅳ collagen (Ⅳ-C),and carried on the upper abdomen CT plain scan,the liver/spleen CT ratio were calculated.Results After treatment,the effective rate of the observation group was 91.4％ (53/58),significantly higher than that of the control group 72.4％ (42/58) (P ＜ 0.05).After treatment,the levels of AST,ALT,γ-GT,TBIL,TC and TG in two groups were decreased significantly compared with the same group before treatment and lower in the observation group (P ＜ 0.05),and liver/spleen CT ratio was increased significantly and higher in the observation group (P ＜ 0.05).After treatment,the levels of LN,PC Ⅲ,Ⅳ-C and HA in two groups were decreased significantly compared with the same group before treatment and lower in the observation group (P ＜ 0.05).Conclusion CDDP combined with polyene phosphatidyl choline can significantly improve the liver function and liver fibrosis in patients with nonalcoholic fatty liver disease,and lower blood lipid,which has high clinical value.

BACKGROUND:The angiogenesis may be related to the proliferation of neural stem ceils,but there is still no unified view.OBJECTIVE:To observe the influence of angiogenesis on neural stem cell proliferation in the subventricular zone of rats after focal cerebral ischemia/reperfusion.METHODS:Male Sprague-Dawley rats were randomly divided into normal group,sham group,vascular endothelial growth factor (VEGF)+cerebral ischemia/reperfusion group,normal saline (NS)+cerebral ischemia/reperfusion group.The injection was done via the lateral cerebral ventricle.Then,each group was subdivided into four groups (1,2,7,14 days after ischemia/reperfusion).Focal cerebral ischemia/reperfusion models were made by the thread method.After modeling,the corresponding intervention was given in each group.The expression changes of Nestin and vWF mRNA in the subventricular zone were detected in all groups by immunohistochemical staining and real-time PCR,respectively.RESULTS AND CONCLUSION:There was a certain increase in vWF and Nestin positive expression in the subventricular zone after cerebral ischemia/reperfusion.At 7 days after ischemia,the expression of vWF mRNA and Nestin reached the peak,indicating the proliferation of neural stem cells in the subventricular zone after cerebral ischemia/reperfusion is associated with the time of angiogenesis.In addition,the expression of vWF mRNA and Nestin was significantly higher in the VEGF+cerebral ischemia/reperfusion group than the other two groups,indicating angiogenesis could promote the proliferation of neural stem ceils in the subventricular zone of rats after cerebral ischemia/reperfusion.

Objective To investigate the effect of endovascular interventional therapy on intracranial aneurysm.Methods We retrospectively analyzed the clinical information and treatment efficacy of 48 patients (53 aneurysms) experienced interventional embolism therapy; these patients were admitted to and received treatment in our hospital from January 2001 to December 2009.Results Among the 53 aneurysms of 48 patients,40 aneurysms were obliterated completely,6 aneurysms 95％ obliterated,5 aneurysms 90％ obliterated and 2 aneurysms failed; 2 aneurysms ruptured and no death was noted during the operation.Six to 12 months after the operation,follow-up of the 46 patients indicated that 2 were recurred under CMA or DSA; 2 was severely disabled; 5 had mild neurological deficits; and the other enjoyed good results.Conclusion Endovascular embolization ofaneurysms is a minimally invasive method with low risk; individualized embolism therapy can improve the prognosis.

BACKGROUNDTo study the arboviruses carried by mosquitoes collected in Hebei Province.

METHODSSamples were collected from mosquito active sites and stored in liquid nitrogen till use. Pools of 20 to 30 mosquitoes were ground after sterilization, centrifugal supernant was inoculated onto C6/36 cell, cytopathic effect was observed for three sequential passages. Positive isolates were identified by IFA and RT-PCR.

RESULTSTotally 1310 mosquitoes were collected from two villages of She county, Hebei province. They were divided into 46 pools and ground respectively. Thirteen positive isolates were obtained. Two isolates reacted with alphaviral antibodies and were amplified by alphaviral primers, nucleotide sequence showed the highest homology (98%) to Getah virus (AY702913.1), so the two isolates were identified as Getah virus.

CONCLUSIONGetah virus was isolated from mosquitoes in Hebei Province. This is the first report of isolating Getah virus from inland of China.

5 strains of virus isolated from Culex tritaeniorhynchus, Anopheles sinensis and Armigeres subalbatus, which caused cytopathic effect in C6/36 cells, had been obtained in the survey of arboviruses in Northwestern Yunnan Province. China. The virus particles displayed 70 nanometers diameter (n=7) with no envelope but spikes on the surfaces. RNA-PAGE of the genomes of the isolates showed 6-5-1 profile. A fragment of the 12th segment sequence was amplified by a pair of specific primers for Kadipiro virus strain JKT-7075 in RT-PCR. The full length of the 12th segment was 758 nucleotides, BLAST analysis revealed the highest identity was 90% to JKT-7075. Phylogenetic analysis demonstrated that the isolates appeared to be Kadipiro viruses (Family Reoviridae). It was the first report of kadipiro virus isolation in China.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.
