ObjectiveTo evaluate the therapeutic effect of three different recovery treatments on herniation of lumbar intervertebral disc.Methods156 cases were divided into three groups, traction of lumbar (Group A, n=52), traction compared with physical therapy(Group B, n=52), traction with massage and electroacupuncture therapy(Group C,n=52). Before and after treatment, the clinical symptoms and signs were assessed and compared. ResultsThe efficiency of alleviative pain and the index of function improvement of lumbar vetebra were higher in Group B, C than that in Group A (P<0.05), higher in Group C than that in Group B (P<0.05).ConclusionThe traction of lumbar with massage and electroacupuncture is preferably effective, and the manual reduction plays an important role.

ObjectiveTo study the effects of early intervention on physical psychomotor development of premature infants.Methods120 survival premature infants were divided into two groups randomly.The infants in intervention group accepted early intervention according to the Early Intervention Program of 0-2 Years Infants,while that in the control did not. The physical and neurological condition and intelligence were tested periodically till 2 years old.ResultsThere were no significant differences between the two groups on physical development.The mental development index(MDI) and psychomotive development index(PDI) in intervention group showed higher than those in control group (P<0.05 and P<0.01 respectively). The abnormal rate of MDI and PDI,the incidence of cerebral palsy in intervention group was lower obviously than that in control group (P<0.01).ConclusionsThe application of early intervention could improve the prognosis of premature infants.

BACKGROUND: Mitofusin2 (Mfn2) profoundly inhibits proliferation and induces apoptosis of vascular smooth muscle cells (VSMCs) through phosphatidylinositol 3 kinase/protein kinase B. Notably, tMfn2, with the transmembrane domain deleted, has a 41%-reduced molecular weight, which possibly exhibits a stronger effect on inducing apoptosis.OBJECTIVE: To investigate the effect of rat tMfn2 gene, with the transmembrane domain deleted, on promoting the apoptosis of VSMCs, and to determine related signal pathway.DESIGN, SETTING AND TIME: A controlled observational study at a gene level was performed in the central laboratory, Department of Cardiology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology between January and October in 2008.MATERIALS: Rat VSMCs and the recombinant adenovirus containing LacZ, Mfn2 or tMfn2 was offered by Professor Chen as a gift.METHODS: The rat VSMCs cultured at 3-10 passages were divided into 4 groups. ①Blank control group: No interventions. ② VSMCs were infected by adenovirus-mediated LacZ, Mfn2, and tMfn2, respectively.MAIN OUTCOME MEASURES: ①Expressions of Mfn2 and tMfn2 following the VSMCs were infected with recombinant adenovirus for 24 hours. ②The apoptosis of VSMCs was determined with flow cytometry and enzyme linked immunosorbent assay at 24, 48 and 72 hours following infection. ③Western blot was used to analyze the expression of phosphorylated AKT following the VSMCs were infected with recombinant adenovirus for 24 hours.RESULTS: ①Both Mfn2 and tMfn2 were expressed in the VSMCs. ②The tMfn2 was superior to Mfn2 in promoting the apoptosis of VSMCs in a time-dependent manner (P<0.01). ③The protein expression of phosphorylated AKT remarkably decreased two groups, especially significant in tMfn2-infected group (P<0,01).CONCLUSION: The tMfn2 can induce the apoptosis of VSMCs more effectively via the inhibition of phosphorylated AKT signaling pathway.

BACKGROUND:Leukocytic infiltration induced by release of inflammatory cytotkines and up-regulation of adhesion molecules is closely associated with the formation of cerebral infarcted focus. The related factors have been widely studied.OBJECTIVE: To explore influence of estrogen on inflammatory reaction in rats after focal ischemia/reperfusion injury.DESIGN: Randomized controlled experiment.SETTING: Nanjing General Hospital, Nanjing Military Area Command of Chinese PLA.MATERIALS:The experiment was performed at the Department of Neurology, Department of Pathology, Nanjing General Hospital, Nanjing Military Area Command of Chinese PLA. Adult male SD rats were selected to establish cerebral ischemic models, with the body mass of 280-350 g.METHODS:The rats were assigned into 3 groups: control group,ovariectomized group and estrogen treatment group (estradiol, 200 μg/kg,subcutaneous injection, once a week for 4 weeks). Four weeks later, models with right middle cerebral artery occlusion (MCAO) for 1 hour and 2 hours as well as reperfusion for 0, 1, 3, 6, 22 and 70 hours were established with thread embolism method. Mean number of infiltrative neutrophils in brain tissue was calculated under microscope with 10 high power fields in ischemic hemisphere with hematoxylin and eosin staining. Expression of nuclear factor-κB was determined with immunohistochemical method.MAIN OUTCOME MEASURES:Infiltration of neutrophils and expression of nuclear factor-κB in brain parenchyma.RESULTS: ①Expression of nuclear factor-κB: There was expression of nuclear factor-κB in the ovariectomized group at hour 1 after ischemia.Positive cells appeared at hour 2 after ischemia in the control group and estrogen treatment group. The expression was in the peak at ischemia for 2hours and reperfusion for 3 hours in the three groups, and decreased gradually. There was slight expression at reperfusion for 70 hours in the ovariectomized group, while there was no clear factor-κB positive cell at reperfusion for 22 hours in the control group and estrogen treatment group.②Infiltrative neutrophils in cerebral ischemic region in the ovariectomized group significantly increased at ischemia for 2 hours and reperfusion for 22 hours. Compared with the estrogen treatment group, there was significant difference (P=0.045). At ischemia for 2 hours and reperfusion for 70 hours,infiltrative neutrophils in the ovariectomized group were more than those in the control group and estrogen treatment group, but there were significant differences only between ovariectomized group and control group.CONCLUSION: Estrogen can inhibit inflammatory reaction after cerebral ischemia/reperfusion injury.

Objective To investigate the clinical significance and changes of neuron-specific enolase (NSE) and S100 protein in blood serum in patients with enterovirus 71 infection.Methods A total of 176 children with enterovirus 71 infection admitted from March 1,2012 through October 31,2012 were enrolled for a prospective and control study.According to diagnostic criteria of the enterovirus 71 (EV71) infection instituted by expert consensus for treatment of severe patients sets in 2011,the patients were divided into three groups:mild group (n =62),severe group (n =65) and critically care group (n =49),and another 30 healthy children served as control group.The demographics of patients including age and sex were comparable between control group and the sick children groups.Four milliliter of peripheral blood were taken from ill children on the first day before treatment and on the first,second,third day after treatment.The blood samples of healthy children were taken on the first day after physical examination.At the same time,the clinical data of blood routine,blood biochemistry,myocardial enzymes and C-reactive protein during the first 24 hours were collected.Immunohistochemical technique was used to study the change of NSE and S100 levels in serum.Data were expressed in mean ± standard deviation ((x) ± s) and were statistically analyzed by using SPSS 13.0 statistical software.Comparisons were carried out among different groups with one way analysis of variance (ANOVA) and between groups were performed with the Student t test.Changes were considered as statistically significant if P values was less than 0.05.Results ①Compared with mild group and control group,the levels of NSE and S100 protein were significantly higher in severe group and critically care group (P ＜0.05).②The serum levels of NSE and S100 protein in severe group were higher than in those in mild group with better outcomes (P ＜ 0.05).Conclusion The serum levels of NSE and S100 protein as biomarkers can be used to evaluate the severity of EV71 infection,and can also be used to determine the efficacy of treatment.
