Objective To understand the relationship between coagulation factors,inflammatory reaction and coronary heart disease(CHD) by analyzing the changes of fibrinogen (Fib), D-dimer (DD) ,C-reactive protein(CRP) and white blood cell (WBC) count. Methods The levels of Fib, DD, CRP and WBC were measured and compared in 91eases with CHD[ineluding 34 cases of acute myocar-dial infarction (AMI group),30 eases of unstable angina peetoris (UAP group) and 27 eases of stable angina peetoris (SAP group)] and 30 healthy controls (healthy control group). Results Plasma con-centrations of Fib, DD, CRP and WBC were the highest in AMI group, followed by those in UAP group,SAP group and healthy control group. There were statistical differences in the above parameters between AMI group and UAP group; so were between UAP group and SAP group. There was no sig-nificant difference between UAP group and healthy control group (P>0. 05). Conclusion The coagu-lation factors and inflammatory reaction are closely associated with occurrence and development of cor-onary heart disease. Four parameters (Fib,DD,CRP and WBC) can be used as adjuvant indicators of differentiating types of CHD and evaluating severity of disease.

BACKGROUND: Clusterin has many biological functions, especially the great protection effects on histiocytes in pathological conditions. It will be helpful to discuss the expression of clusterin in the spinal cord injury tissue to further identify the mechanism of secondary spinal cord injury and to provide possible treatments.OBJECTIVE: To observe the expression of clusterin in acute spinal cord injury tissue.DESIGN: Randomized controlled animal study.SETTING: Department of Orthopaedics, First Affiliated Hospital, China Medical University.MATERIALS: The experiment was performed in Experimental Animal Department, China Medical University from January 2003 to January 2006.A total of 65 adult healthy SD rats of 250-300 g provided by Experimental Animal Department, China Medical University were selected. METHODS: All the rat models by modified Allen assay for acute spinal cord injury were randomized into injury group, sham operation group and normal control group with 30, 30 and 5 rats in each group, respectively.The rat injury models in dorsal spinal cord were prepared by modified Allen assay: the target injury site was T10 segment; the sham operation group was given T10 total laminectomy. The normal control group received no operation. Rats in the injury group and sham operation group were killed at hour 12, days 1, 3, 7, 14 and 21 after spinal injury and operation with 5 rats at each time point, respectively. Frozen sections of the injury part were made at different time point after injury. Degeneration and necrosis of spinal cord injury tissues were observed with hematoxylin-eosin (HE) staining. Deposition and disposition of positive reactants of clusterin were observed with clusterin immunohistochemical staining. Average gray value of positive reactants of clusterin was detected with semi-quantitative image analysis (went with the intensity of clusterin immunoreaction in inverse ratio).MAIN OUTCOME MEASURES: ①Degeneration and necrosis as well as positive expression of clusterin of spinal cord injury tissues of rats in each group. ②Average gray value of clusterin positive reactants in spinal cord injury tissues of rats in each group.RESULTS: A total of 65 rats were involved in the result analysis, without dropout. ①In the injury group, positive expression of clusterin began to increase at day 1 after injury, reached peak at about day 7, declined gradually at day 14 and tended to be stable at day 21 after injury. This dynamic course of change was along with the prolongation of time. The expression of clusterin appeared in the sham operation group and normal control group at each time point, and the expression was stable. There was no dynamic change with the prolongation of time. ②In the injury group average gray value of positive reactants of clusterin was significantly lower at days 1, 3,7, 14 and 21 as compared with that in the sham operation group and normal control group (t=6.33-15.57, P ＜ 0.01 ). There was no significant difference in average gray value of positive reactants of clusterin at each time point in the sham operation group as compared with the normal control group (P ＞ 0.05).CONCLUSION: The expression of clusterin increases greatly in acute spinal cord injury tissues, and has dynamic change, which is the same with spinal cord injury.

In recent years,two important component proteins of the calcium release-activated calcium channel (CRAC) were identified fromDrosophila cells by RNA interference technique,including the calcitum sensor stromal interaction molecule 1 (STIM1) on the endoplasmic reticulum and the CRAC channel protein Orail on the cell membrane.Studies have shown that STIM 1 and Orail have regulatory effects on vascular smooth muscle cells,platelets,vascular endothelial cells and other cells.They play important roles in the aspects of vascular smooth muscle cell phenotypic modulation,hemostasis,thrombosis,and neovascularization.It shows that they both may be closely associated with ischemic cerebrovascular disease.This article reviews the advances in research on STIM1 and Orail proteins in ischemic cerebrovascular disease in order to investigate the possibility of STIM1/Orai1 as a new target in the prevention andtreatment of ischemic cerebrovascular

Type 1 diabetes is pathologically characterized by autoimmune insulitis-related islet β-cell destruction.Although intensive insulin therapy for patients with type 1 diabetes can correct hyperglycemia,this therapy does not effectively prevent diabetes-related cardiovascular complications.Hence,preservation of natural β-cell function is critical for the prevention of diabetes-related complications.Receut studies have shown that autologous hematopoietic stem cell transplantation ( A HSCT) is a new promising approach for the treatment of type 1 diabetes by reeonstitution of immunotolerance and preservation of islet β-cell function.Here we introduce the key results of a clinical trial ( NCT 01341899,ClinicalTrials.gov) performed in Chinese type 1 diabetes patients ( most of them with diabetic ketoacidosis at onset ) and discuss the potential mechanisms underlying the action of HSCT and its prospects in the clinical management of type 1 diabetes.

Cutaneous wound healing is a complicated multiatep process with numerous mediators that act in a network of activation and inhibition processes. Nonhealing chronic wounds decrease the quality of Life. Recombinant growth factors, currently used in clinic, fail to provide a sustained repair function at the wound due to their inadequate biological availability and transient half-time. Recent attention has focused on gene therapy, which might become a significant treatment modality for those wound healing pathologies refractory to other wound management approaches. This review discusses the potentials and limitations of current genetherapy for the treatment of wounds, current ongoing clinical trials, and possible future directions in this exciting field.
