Objective To explore the relevance among the cognition function,the autonomic nerve function,and the serum level of monoamine neurotransmitter in the patients with post-stroke depression(PSD).Methods The event-related potentials(ERP),the sympathetic skin response(SSR),and the serum levels of monoamine neurotransmitter were taken in the 33 cases with PSD(PSD group)and 30 normal collators(NC group),the mean of each target was tested by Pearson multiple correlation analysis.Results Comparing with the NC group,the PSD group demonstrated that the latency phase had been prolonged and the wave amplitude reduced significantly(all P

Objective To investigate the association between HbA1c status,arterial stiffness and endothelial function in subjects with type 2 diabetes mellitus(DM).Methods The study group consisted of 338 DM patients,including 74 subjects with normal HbA1c(≤ 6.0％)(Group A),102 subjects with mildly increased HbA1c(HbA1C increased by less than 6.5％)(Group B)and 162 patients with high HbA1c level (HbA1c increased by more than 6.5％)(Group C).All patients were evaluated for glucose,HbA1c,TC and TG.Pulse wave velocity(PWV)and flow-mediated dialation(FMD)were performed simultaneously.Results Compared with Group A,Group B and C had higher baPWV([1734 ± 343]cm/s vs.[1537 ± 313]cm/s and [1853 ± 364]cm/s vs.[1537 ± 313]cm/s).Patients in Group C had a higher baPWV than those in Group B ([1853 ± 364]cm/s vs.[1734 ± 343]cm/s,P =0.006).The patients in group A had a lower level of FMD than that of group B and C([4.20±3.13]％ vs[5.29±3.92]％,[4.09±2.79]％ vs.[5.29±3.92]％,P＜0.01).Leaner association analysis showed a positive correlation between baPWV and HbAlc(r =0.53,P ＜0.01).baPWV was negatively correlated with FMD(r =-0.25,P ＜0.01).Logistic regression analysis showed that HbA1c(OR32.19％,CI 11.26 ～53.12,P＜0.001),age(OR 14.21,95％ CI 11.43 ～ 17.00,P＜0.001),systolic blood pressure(OR 7.36,95％ CI 6.12-8.59)and TC(OR:0.31,95％ CI:9.97-70.64)were independent predictors for the increased arterial stiffness(baPWV).Conclusion Arterial stiffness parameters varied significantly across subgroups of patients with different levels of HbA1c and the arterial stiffness was positively associated with deranged glucose homeostasis.

This study was aimed to compare the function of dendritic cells (DCs) in patients of Y in-Huang syn-drome and Y ang-Huang syndrome from the peripheral blood of HBV related hepatic failure. Jaundice patients of HBV related hepatic failure were divided into two groups, which were the Y ang-Huang syndrome group and Y in-Huang syndrome group. And a healthy control group was also established. The DCs were separated and cultured in vitro from PBMCs in the peripheral blood. Surface molecules such as HLA-DR, CD80, CD86, CD83 and CD1αwere detected by the flow cytometry. And the level of IFN- α and IL-4 in the supernatant of DCs were also de-tected. The expression difference of inflammatory cytokines and immune cells between Y in-Huang and Y ang-Huang syndrome in patients of HBV related hepatic failure were compared. The results showed that compared with healthy people, the expression rate of DCs phenotype such as HLA-DR, CD1α, CD83, CD80, CD86 in patients of HBV related hepatic failure was significantly decreased (P < 0.01); the excreted factor IFN-α had a significant rising (P < 0.01). Compared to Y ang-Huang syndrome group, the expression rate of CD83 and CD86 in the Y in-Huang syndrome group of HBV related hepatic failure patients was significantly reduced (P < 0.01). And the ex-creted factor of IL-4 had a significant rising in Y in-Huang syndrome group (P < 0.01). Compared to the Y in-Huang syndrome group, the excreted factor IFN-α in the Yang-Huang syndrome group had a significant rising (P< 0.01). It was concluded that DCs function of patients with HBV related hepatic failure in both Y in-Huang syn-drome and Y ang-Huang syndrome group showed low immune function. And the immune function of the Y in-Huang syndrome group was lower. There was excessive releasing of inflammatory factors in the Y ang-Huang syn-drome group. And there was enhanced anti-inflammatory cytokine expression in the Y in-Huang group.

Objective To observe the effect of scalp-acupuncture combined with physical therapy on spastic cerebral palsy.Methods 80 children with spastic cerebral palsy were randomly divided into observation group and a control group,40 cases in each group.The observation group was treated with scalp-acupuncture combined with physical therapy,and the control group with physical therapy only.They were assessed with the Functional Independence Measure for children(WeeFIM) and the Gross Motor Function Measure(GMFM) before and 3 months after treatment.Results No side-effect was observed during the treatment.The scores of WeeFIM and GMFM of the observation group were significantly superior to the control group(P<0.05).Conclusion The scalp-acupuncture can improve the efficiency of physical therapy on motor function in the children with spastic cerebral palsy.

As an endogenous organism protective measure in vivo, preconditioning/ postconditioning in the process of ischemia/reperfusion may play common protective mechanisms, such as reducing the generation of oxygen free radicals, activating adenosine receptor, increasing endogenous nitric oxide and heat shock protein, inhibiting immune inflammatory response and neuronal apoptosis, activating intracellular signal transduction pathways, opening mitochondrial ATP-sensitive potassium channels, as veil as closing mitochondrial permeability transition pores. Investigating the common target of these mechanisms may provide a new theoretical basis for developing new drugs and reducing ischemia/reperfusion injury.

Remote organ ischemic preconditioning is to conduct a transient and sublethal ischemic adaptation in non-vital organs before occurring cerebral ischemia/reperfusion injury in remote vital organs. Remote organ iscbemic preconditioning has been studied for as long as 15 years in the field of myocardial iscbemia. However, only recently it has become a therapeutic strategy for the treatment of cerebrovascular diseases, This article briefly reviews the methods and mechanisms involved in the protective effects of cerebral ischemia of remote organ ischemic preconditioning.

Objective To study the protective effect of different doses of rosiglitazone (RSG)against focal cerebral ischemia-reperfusion injury in rats．Methods Forty male sprague Dawley rats were randomly divided into the following groups：sham-operation，control，lowdose RSG(1 mg/kg·d)，moderate-dose(2 mg/kg·d)，high-dose(4 mg/kg·d)goups(n=8 in each grow)．A rat model of middle cerebral artery occlusion for 2 hours and reperfusion for 22 hours were induced by the intraluminal suture method．An automatie biochemical analyzer was used to detect the blood glucose and lipid levels．A solid phase sandwich enzyme-linked immunosorbent assay was used to determine serum insulin levels，and the insulin sensitivity indexes were calculated．The effect of rosiglitazone on infarct volume and behavioristics was observed．Results Compared with the control group，the infarct volume was significantly reduced，and the neurological function scores were improved significantly in each RSG group(P<0．05 or P<0．01)．The insulin sensitivity was significantly increased(P<0．05 or P<0．01)，and hyperglycemia was reduced significantly after cerebral ischemia(P<0．05)and showed a dose-dependent manner.Conclusions RSG has obvious neuroprotective effect against cerebral ischemia／repeffusion injury in rats．Its mechanism may be associated with the increase of insulin sensitivity．
