Objective To observe the clinical effect of plasmin combined with aspirin in treating acute cerebral infarction and to explore the influence to blood rheology and nerve function.Methods 148 cases with acute cerebral infarction were randomly divided into two groups.The control group (n =74) was treated by honghua injection.The study group (n =74) was treated by plasmin combined with aspirin.After treatment,the clinical effect,blood rheology and neurological recovery were observed.Results The total effective rate of the study group was 97.2%,which was significantly higher than that of the control group(74.3%) (x2 =15.88,P < 0.05).The blood rheology indexes of the two groups had improved and neural function of the two groups was restored,but those in the study group were obviously better than control group (t =3.56,3.42,4.26,3.22,4.16,all P < 0.05).Conclusion Plasmin combined with aspirin in treating acute cerebral infarction has accurate clinical curative effect,can markedly improve the blood rheology and promote nerve functional recovery,is worth of clinical spreading.
2.Endoplasmic reticulum stress and cognitive impairment
International Journal of Cerebrovascular Diseases 2014;22(3):222-226
In eukaryotic cells,endoplasmic reticulum (ER) is a locus where the proteins are modified,folded and the calcium is stored.When the harmful factors,such as ischemia/hypoxia,lack of nutrients,viral infections,and toxins cause the homeostasis damage in the endoplasmic reticulum,the accumulation of unfolded or misfolded proteins and the calcium imbalance may result in endoplasmic reticulum stress (ERS).ERS induces the expression of endoplasmic reticulum chaperones and endoplasmic reticulum associated degradation components,and reduces the load of the endoplasmic retlculum by temporarily reducing protein synthesis.Studies have shown that many diseases that can induce cognitive impairment are all associated with ERS.
3.Neurogenesis, vascular endothelial growth factor and vascular cognitive impairment
International Journal of Cerebrovascular Diseases 2015;(3):224-228
Neurogenesis is a dynamic process of neural precursor cel self-proliferation and differentiation into new neurons. Studies have confirmed that hippocampal neurogenesis may improve cognitive function, and vascular endothelial growth factor (VEGF) plays an important regulatory role in neurogenesis. This article reviews the mechanism of VEGF promoting neurogenesis and the role of neurogenesis in improving vascular cognitive impalrment.

Objective To investigate the effects of angiotensin Ⅱ (Ang Ⅱ) or high glucose on the toll-like receptor 4 (TLR4) expression,inflammatory cytokines and fibrotic factors in human tubular epithelial cells (HK-2),revealing the innate immune-related pathogenesis of diabetic nephropathy (DN) which may have clinical implications.Methods Three TLR4 siRNA sequences were designed and synthetized.After transfection,the most effective siRNA was selected to use for further expriments.The experiment consisted of 2 parts.Part 1:Cells were divided into three groups:normal-glucose group (NG,5.5mmol/L glucose),mannose group (M,5.5 mmol/L glucose + 19.5 mmol/L mannose),High-glucose group (HG,25 mmol/L glucose),preliminary validated the effects of high glucose and high osmotic pressure.Part 2:Cells were divided into seven groups:NG group,HG group,Ang Ⅱ group,Ang Ⅱ + negative group,HG+ negative group,Ang Ⅱ + siRNA group and HG+ siRNA group.Real time PCR was used to analyze the mRNA expression of TLR4,myeloid differentiation factor 88 (MyD88),heat shock protein 47 (HSP47).Western blotting was used to observe the protein expression of TLR4,MyD88,HSP47,NF-κB,type Ⅳ collagen (ColⅣ).ELISA was used to detect the expression of monocyte chemotactic protein-1 (MCP-1) and interleukin-6 (IL-6).Results Compared with NG group,TLR4,MyD88,HSP47 mRNA and TLR4,MyD88,NF-κB,ColⅣ,HSP47 protein were highly expressed under high glucose or Ang Ⅱconditions (P < 0.01),and the expression levels of MCP-1 and IL-6 also increased significantly (P < 0.01).Compared with HG or Ang Ⅱ group,the above indicators were obviously inhibited in the TLR4 siRNA groups (P<0.01).Comparison between blank vector transfected groups and HG group as well as Ang Ⅱ group indicated no statistic significance (P > 0.05).Conclusions Both Ang Ⅱ and high glucose stimulate TLR4 expression,which result in the up-regulation of inflammatory and fibrotic factors in HK-2.Specific target of TLR4 gene silencing can block the TLR4 pathway that is activated by high glucose and Ang Ⅱ,and thus reduce the inflammatory and fibtogenic factors' release.TLR4 signal is the common innate immune response pathway which induces the release of inflammatory and fibrotic factors in HK-2 under high glucose or high angiotension conditions.
