1.Detection of Fas on colonic apoptosis epithelium in ulcerative colitis by double staining immunohistochemistry
Journal of Chongqing Medical University 1986;0(04):-
Objective:To discuss the role of Fas/FasL-mediated colonic epithelial apoptosis in the pathogenesis of ulcerative colitis(UC).Methods:Expression of Fas,FasL and M30(a new epithelium apoptosis marker) antigen on colonic mucosa of 35 patients with UC and 15 control populations were detected by IHC.Each marker was analyzed by image analysis system.Co-expression of Fas and M30 was observed through serial sections and double staining IHC.Results:The expression of Fas,FasL as well as M30 in UC increased considerably compared with controls (P
3.Electromagnetic fields and neovascularization of tissue-engineered grafts
International Journal of Biomedical Engineering 2008;31(2):94-97
Neovascularization is one of the crucial challenges in tissue-engineered grafts.In order to find sdution to the problem,endothelial cells and animals were exposed to electromagnetic fields to examine the formation of new vascular.This review gives an overview of the effects of electromagnetic fields on the neovascularization of tissue-engineered grafts.
4.In vivo animal models of cerebral vasospasm following subarachnoid hemorrhage
International Journal of Cerebrovascular Diseases 2010;18(6):477-480
Delayed cerebral vasospasm is the leading cause of death in patients with subarachnoid hemorrhage. A good in vivo animal model of cerebral vasospasm after subarachnoid hemorrhage helps to understand the occurrence, development of this cerebral vasospasm, and the complicated and various pathophysiological mechanisms. It will provide important information for clinical interventions
5.Study on the pathogenesis and imaging of atherosclerosis
International Journal of Biomedical Engineering 2013;36(6):362-366
Atherosclerosis (AS) is a multi-factor disease,with complex etiology.It is associated with vascular abnormalities and changing vascular wall composition.AS mainly involve large and medium sized arteries,which may cause multiple organ lesions including heart and brain tissue ischemia and necrosis,myocardial infarction,stroke and other serious diseases.Its pathogenesis has not been finally clarified.This article gives review on pathological changes,etiology and mechanism of AS,as well as its imaging performance.

7.Oncosis in human peripheral blood T lymphocytes
Chinese Journal of Immunology 1985;0(01):-
Objective:To observe oncosis in human peripheral blood T lymphocytes.Methods:Peripheral blood T lymphocytes of healthy adult was separated with Percoll(1.073 g/ml)and harvested by using nylon column.The cultured cells were divided into control and dexamethasone(DXM)group,and cell morphology was observed through light microscope,electron microscope and fluorescent microscope.And incidence rate of oncosis was analyzed by flow cytometry.Results:①Oncosis could be observed in cultured T lymphocyte after 96h.②In different concentrations of DXM group(1?10-6,1?10-5,1?10-4,1?10-3mol/L),The incidence of oncosis T lymphocytes was(3.49?0.42)%,(5.17?0.48)%,(8.44?0.72)%,(17.93?1.50)%.③During different cultured period(48,72,96,120h),The oncositic rate of T lymphocytes in DXM group was(0.53?0.10)%,(6.36?0.80)%,(20.60?1.59)%,(25.56?1.76)%.Conclusion:Oncosis can be seen in human peripheral blood T lymphocytes,and DXM could induce oncosis.
8.Advancement in Liver Transplantation for Hepatic Metastasis from Neuroendocrine Tumor
Chinese Journal of Bases and Clinics in General Surgery 2003;0(06):-
Objective To summarize the application and advancement of liver transplantation for hepatic metastasis from neuroendocrine tumor. Methods Domestic and overseas publications on the study of liver transplantation for hepatic metastasis from neuroendocrine tumor in recent years were collected and reviewed. Results Liver transplantation can offer good relief of symptoms, long disease-free intervals, and potential cure in individual patients with hepatic metastatic tumor. Important selection criteria are well-differentiated tumors and a low proliferation rate (Ki67
9.The important factors influencing the functions of periodontal ligament stem cells
Journal of Practical Stomatology 2000;0(05):-
Periodontal ligament stem cells(PDLSCs) are not only the crucial type of cells in maintaining dynamic homeostasis and wound repair of periodontal tissues but also the basis for novel therapeutic strategy for periodontal regeneration.Although possessing the excellent proliferation and differentiation ability,PDLSCs behave differently under various conditions representative of several influential factors.Understanding of these influential factors will help us to exploit more about PDLSCs,and more importantly,lead a new modality in treating periodontal diseases based on stem cells.Here we review multiple important factors affecting function of PDLSCs and propose its use in future regenerative therapy of periodontal defects.

Objective To investigate the clinical characteristics of juvenile rectal carcinoma in order to improve the diagnostic level and therapeutic efficacy at the early stage. Methods Clinical data, including clinical manifestations, misdiagnosis, clinical pathology, treatment, and prognosis, from 89 cases of juvenile rectal carcinoma were analyzed retrospectively and compared with those from 440 cases of senile rectal carcinoma. Results ① The main manifestations of juvenile rectal carcinoma included anal and rectal pains, abdominalgia, abdominal distention, and sacrococcygeal pain. ② In juvenile group, carcinomas with distance less than 9 cm and less than 7 cm away from the anal verge amounted to 92.13% and 69.66%, respectively (average distance: 5.43 cm). ③ The average period of misdiagnosis in juvenile group was 5.7 months with a misdiagnosis rate of 97.75%, significantly higher than that in senile group ( P
