Objective To investigate effect of interferon gemma on immune factor and CD69, CD107a in patients with delayed type hypersensitivity by interferon gamma.Methods 76 cases with delayed type hypersensitivity were selected and divided into 2 groups.38 cases in control group were treated conventional therapy, 38 cases in experiment group were treated by interferon gamma.Peripheral blood CD69, CD107a, immune factor, T cell subsets and the treatment efficiency were compared after the treatment.Results Compared with the control group, the serum CD69 and CD107a levels were lower in the experimental group (P<0.05), serum IgG and IgA levels were higher, the serum IgE level was lower (P<0.05), and the CD3 +,CD4 +,CD4 +/CD8 +level was higher, serum CD8 + was lower (P<0.05) .The effective rate of the treatment group was significantly higher than that of the control group (P<0.05) .Conclusion Interferon gamma has good clinical effect in the patients with delayed type hypersensitivity, and can effectively reduce the levels of CD69 and CD107a in the peripheral blood, and regulate the immune function of the body.

Objective To analyze the clinical presentation and the effects on both mothers and fetuses with HELLP syndrome induced hyregtensive disorder complicating pregrancy and to investigate the effective methods for diagnosis and treatment. Methods 15 cases of HELLP syndroms were retrospectively analyzed on material and perinatal outcomes. Results In 15case of women with HELLP syndrome, all of them presented antepartum HELLP. Mean gestational age at delivery was 34 weeks. Severe maternal complications included placental abruption,DIC ,postpartum hemorrhage,fetal distress, et al. All of them underwent cesaresn section and required transfusions with blood or blood products. 1 case of perinatal death was related to placental abruption. Conclusion HELLP syndrome is a severe obstetric complication. Better prognosis may be achiveved by early diagnosis, synthetic therapy and optimal termination of pregnancy.

It is important to explore the fundamental medical concepts which can enhance the overall quality of medical students in the department of geriatrics during clinical practice. These funda-mental medical concepts include medical humanistic spirit,holistic medicine,health management and patient-physician communication. Specific measures include improving emotional communication of clini-cal interns in department of geriatrics with elderly patients,training student's thinking as a whole towards multiple system disease in the elderly,training students to assess and manage elderly patients from a vari-ety of perspectives and improving doctor-patient communication skills by routine clinical teaching and teaching ward round. All these concepts will help improve the working ability and medical ethics of clini-cal interns and enable them to adapt to the clinical work quickly. So they can become qualified doctors.

Objective:To observe expression of stathmin gene in laryngeal squamous cell carcinoma(LSCC) and relation between expression of stathmin gene and occurance and development of LSCC.Method:The expression of the stathmin gene was determined in 35 LSCC of specimens and 18 normal laryngeal tissues(NLT) of specimens by in situ hybridizaion with Digoxigenin labled probe of stathmin mRNA.Result:Expression of stathmin gene was observed in 35 cases of laryneal squamous cell carcinoma tissue (positive rate, 69%) and positive signal was observed in both cytoplasm and nuclear. Among 18 cases of normal tissue, only 6 showed weak positive signal. There was significant difference in expression of stathmin gene between laryneal squamous cell carcinoma tissue and nomal tissue.Conclusion:Expreesion of stathmin gene may play a key role in the pathogenisis and development of laryneal squamous cell carcinoma. It may be a very important biotherapy target in the treatment of laryneal squamous cell carcinoma.

Objective To study the chronic neurotoxicity of aluminum through observing the adverse effect of long term intake of aluminum on the memory of rats.Methods 40 Wistar rats were randomly divided into 4 groups and given Al2(SO4)3 through drinking water for 6 months,the concentration of Al3+ in the waters were 0.12 mg/L,40 mg/L,400 mg/L and 2 000 mg/L respectively,then passive avoidance tests were carried out.One month before pregnancy,the dams were given Al3+ of 40 mg/L and 2 000 mg/L respectively,after the offspring were born,the group given high[Al3+] was subdivided into two groups,one continuously drank the water with high [Al3+],the other drank the water without Al3+.The dams drinking water with low [Al3+] and their offspring continued to drink the same water as before.At the age of three months,all the offspring were examined with passive avoidance tests.Results The memory acquirement in all adult rats were not abnormal,but memory retention were severely damaged (P0.05).The rats continuously drinking water with high [Al3+] after birth had significant damage both in memory acquirement and in retention (P

Objective To evaluate the role of MRA,IPVG and DUS in the hemodynamics studies of portal hypertension.Methods Thirty-eight patients with portal hypertension were examined with Philips Gyroscan 1.0 Tesla MR imaging system.3D-DCE MRA and 2D-PC MR were used for study of portal venous anatomy and its hemodynamics.The results were compared with those obtained from IPVG and DUS.Results 3D-DCE MRA could clearly display the anatomical imaging of portal venous system and its imaging quality was better than that of IPVG.The data of hemodynamics from 2D-PC MR including diameter,blood velocity and blood flow were closely correlated to those from DUS.Conclusion As a non-invasive technique,MRA can display the anatomy of portal venous system and measure its hemodynamics exactly.It should be applied as the first choice in hemodynamics evaluation for portal hypertension.
