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

Objective To investigate the regulating effect of Jianpixiaoshi Decoction(JPXSD)on gastrointestinal motility in rats of functional dys-pepsia(FD)with spleen deficiency syndrome. Methods Forty healthy male SD rats were randomly divided into four groups:normal control group, model group,model traditional Chinese medicine(TCM)group and model western medicine group. Except for the normal control group,FD model of spleen-deficiency type was established by swimming to exhaustion on alternate days and alternating feeding of cabbage and lard for 25 days. Corre-sponding drugs were then administrated to those four groups:distilled water,JPXSD and Mosapride distilled water solution once a day by gavage for 7 days. Symptoms and body weights of these rats were observed and recorded during the experiment. After the last of drug administration,all groups were fasted for 24 hours. Nutritious semisolid paste marked with ink was given orally to the rats,GER and IPR of 1 hour were detected under anesthe-sia by sodium thiopental and blood were collected at the same time. The concentration of serum SP and SS were measured by ELISA according to the instructions. Results JPXSD improved the symptoms of model rats. Model TCM group showed significantly increased body weight,higher GER, lower IPR,higher serum SP level and lower SS level when compared to model group(P<0.05). Conclusion JPXSD could improve the symptoms of rat with spleen-deficiency,raise its body weight,accelerate the decreased gastric emptying and bring back the hyperactive small intestinal move-ment to normal. The regulating role of JPXSD may be realized through the increase of serum SP level and decrease of SS level.

One hundred and sixteen cases of vertebral artery type of cervical spondylopathy were treated by electroacupuncture on Fengchi (GB 20) and Jiaji (Ex-B 2, C2-5), cupping plus manipulation of pulling the rotated neck. The result showed 89 cases were cured, 21 cases were improved and 6 cases failed with the total effective rate of 94.8%.

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.

Studying of atherosclerosis is more than a hundred year.There are many theories about this disease,but now most of us seems to agree with the stress-reponse theory.Heat shock proteins are the products produced at the first stage of atherosclerosis.And someone think that it may have something to do with atherosclerosis.This paper discussed the heat shock proteins and atherosclerosis respectively,and emphasized the relationship between them.

AIM:To investigate the current situation and future trend of the use of antihypertensives in Fuzhou District METHODS:The data of antihypertensives used in 10 hospitals of Fuzhou District during the 1997～2000 were analysed by DDD RESULTS:15 different kinds of antihypertensives were used in these 10 hospitals and captopril,nifedipine and HCT were the first 3 agents in DDDs order in 4 years The use of long-acting calcium antagnosts,felodipine slow-released tablets,increased year by year CONCLUSION:Economical feasibility and effectiveness are the basic principle for using drugs The long-acting preparations are gradually attracting attention of clinical doctors because they are convenient in taking and less in ADRs

Objective To observe and compare anatomical position between pediatric internal jugular vein and common carotid artery in children patients of different ages with ultrasonic technique.Methods Four hundred and ninety-six cases of pediatric patients undergoing selective operation,ASA physical status Ⅰ or Ⅱ,were selected in this study,they were 380 males and 116 females ranging from 0 to 12 years.Image position of internal jugular vein and common carotid artery above the clavicle were detected with ultrasonic technique for all pediatric patients,positions of internal jugular vein and common carotid artery for different patients were classified according to different angles,anatomical position between pediatric internal jugular vein and common carotid artery in different age groups (newborn group,infant group,toddler group,preschool children group and school-age children group) were compared.Results In area between 0°-30°,the ratios of right puncture of infant group,toddler group,preschool children group and school-age children group were significantly higher than those of the left (infant group: 42.3% vs 0%;toddler group: 48.8% vs 1.6%;preschool children group: 57.5% vs 2.7%;school-age children group: 58.0% vs 2.1%)(P<0.01).In area between 30°-60°,the ratios of the right puncture in all groups were significantly higher than those of the left (newborn group: 45.0% vs 10%;infant group: 44.2% vs 23.1%;toddler group: 46.3% vs 19.5%;preschool children group: 35.4% vs 19.5%;school-age children group: 35.1% vs 20.2%) (P<0.05 or P<0.01).In areas between 60°-90°and at 90°,the ratios of the right puncture in infant group,young children group,preschool children group and school-age children group were significantly higher than those of the left (P<0.01).In areas of >90°,there was no statistical difference between the ratios of the right puncture and the left in all groups.Conclusion The success rate of right internal jugular vein puncture of children was higher than that of the left.Conditions in the newborn group were different from that in the other age groups.

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

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.
