The spleen lymphocyte electrophoretic mobility was used as an indicator for determining the effect of vitamin E (VE) oa protecting the spleen lymphocyte membrane from irradiation injury. The result demonstrated that after whole body irradiation of mice with 4.8 Gy X-ray, the spleen lymphocyte electrophoretic mobility (SL-EPM) of the animals administered 100ppm VE for six weeks was significantly higher than that of the control (p

Objective To investigate the cause, the clinical manifestation, the diagnosis and the treatment of subacute thyroiditis. Methods The medical history, clinical characteristics, laboratory data, nuclear medicine tests and treatment of 76 cases of subactue thyroiditis were analyzed. Results Subacute thyroiditis was more common in women than men, and 76 3% cases with subacute thyroiditis occurred during 30～49 years old. Almost all cases were characterized by enlargement of the thyroid with pain and tenderness, 49 cases of which showed that radioiodine uptake was low with increased serum thyroid hormone levels. 25 cases were treated with prednisone, 23 cases were treated with intrathyroid injection of dexamethasone, 23 cases were treated with intrathyroid injection of dexamethasone and triamcinolone, all recovered well, and 5 cases underwent operation incorrectly. Conclusions Confirmation of subacute thyroiditis should put emphasis on a complete medical history, physical examination and necessary tests. Nuclear medicine tests play an important role in diagnosis of subacute thyroiditis, and the diagnostic drug treatment or fine needle aspiration biopsy may be performed in suspected cases. Glucocorticoid is the best medicine for treating this kind of disease. There is no need for operation therapy of subacute thyroiditis.

Objective To investigate the early and long-term effects of enhanced ischemia/reperfusion injury on the transplanted abdominal aorta. Methods Abdominal aorta grafts from Sprague-Dawley (SD) rats were cold stored for 1 or 24 hours, and they were orthotopically transplanted to SD or Wistar recipients. The pathohistological changes and the expression of TGF-? 1 in the grafts were observed. The levels of serum lipid peroxides before and after transplantation were also measured. Results The intima was significantly thicker in aorta transplants which was cold stored, both in SD→SD and SD→Wistar groups 10 weeks and 6 weeks after transplantation, whereas grafts which were cold stored for 24 hours showed pronounced thickening as early as 2 weeks after transplation. Serum lipid peroxides levels were elevated significantly 2 hours post-transplantation in all groups, but they were lowered 4 and 24 hours post-transplantation. The expression of TGF-? 1 in 24 hours of ischemia became stronger 1 week after transplantation regardless the difference in strains of the animal. Conclusions The enhanced ischemia/reperfusion injury can aggravate the infiltration of inflammatory cells, intensify the expression of TGF-? 1, accelerate the thickening of intimal layer.

Objective To analysis curative effect of triple therapy and sequential therapy for eradication of Helicobacter pylori in patients with long-term aspirin use.Methods 52 patients with long-term aspirin use who were diagnosed with helicobacter pylori infection were collected.All patients were divided into sequential group and triple group according to different drugs classified, each 26 cases in each group were given corresponding drug treatment, after the end of treatment, the serum pepsinogen, Hp-IgG antibody levels and Helicobacter pylori clearance rate were detected in all patients. Results After treatment, compared with the triple Group, in the sequential group, the levels of serum PG I and PG II were lower, and PGⅠ/PGⅡwas higher, and the differences were statistically significant (P<0.05);the serum Hp-IgG antibody levels were lower in the sequential group (P<0.05);the Hp clearance rate of patients in the sequential group was higher (P<0.05).Conclusion Compared with triple therapy, sequential therapy can lower serum PG, PG II and Hp-IgG levels, and improve the Hp clearance rate and clinical efficacy, have guiding significance to clinical.

Objective To investigate the role of expression in the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma. Methods Seventy cases of thyroid lesions (including 15 cases of follicular adenomas, 15 cases of adinomatous goiters, 30 cases of papillary carcinomas and 10 cases of follicular carcinomas) were collected, and CD10 expression was detected by means of immunohistochemistry in above thyroid lesions. Results Seven of 9 cases of follicular variant of papillary carcinoma were CD10 positive (77.8), and 8 of 10 cases of follicular carcinoma were CD10 positive (80.0). However, CD10 was negative in all cases of non-follicular variant of papillary carcinoma, follicular adenoma, adinomatous goiter and normal thyroid tissue. Conclusion The detection of CD10 expression is useful to the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma.

Objective To explore the significance of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) for the death risk evaluation in elderly patients with chronic disease in five years.Methods A total of 765 elderly patients with chronic disease[136 patients with coronary heart disease (CHD),76 patients with hypertension disease (HD),86 patients with chronic obstructive pulmonary disease (COPD),75 patients with Type 2 diabetic mellitus (T2DM),76 patients with cerebral infarction (CI),73 patients with coronary heart disease combined with hypertension,71 patients with coronary heart disease combined with chronic obstructive pulmonary disease,61 patients with coronary heart disease combined with diabetic,51 patients with coronary heart disease combined with cerebral infarction,and 60 patients with three comorbidity] were classified into the survival group (312 cases) and the death group (453 cases) according to disease prognosis.The serum NT-proBNP levels of 88 healthy controls and 765 elderly patients with chronic disease were determined by bi-directional lateral flow immunoassay.The death events were followed up and observed for an average of 5 years.The results were analyzed statistically.Results The serum NT-proBNP levels in the death group with various diseases were significantly higher than the survival group (P ＜0.01),the patient's age and the proportion of male in the death group and the survival group had no significant difference (P ＞ 0.05).The serum NT-proBNP levels,the patient's age and the Proportion of male in the death group with various elderly chronic diseases had no statistical significance (P ＞ 0.05).The serum NT-proBNP levels in the death group with various elderly chronic diseases had no statistical significance (P ＞ 0.05),and were significantly higher than the survival group (P ＜ 0.01).The patient's age and the proportion of male in the death group and the survival group had no significant difference (P ＞ 0.05).The serum NT-proBNP levels in the death group in the different periods had statistical significance (P ＜ 0.01),and were significantly higher than the survival group and healthy control group (P ＜ 0.01).The more shorter of the survival time was,the higher the serum NT-proBNP 1eve was.The serum NT-proBNP levels were negatively correlated with the survival time of the patients (r =-0.378,P =0.000).The receiver operator characteristic (ROC) curve indicated that the optimal cut-off values of serum NT-proBNP levels for the death risk evaluation in elder patients with chronic disease were 1 499.50 ng/L.Kaplan-Meier survival curve showed that the survival rates of serum NT-proBNP levels had significant difference (P ＜0.01).The higher the serum NT-proBNP level was,the more shorter of the Survival rates were.Conclusions The levels of serum NT-proBNP have an important prognostic value in the death risk evaluation in elderly patients with various chronic disease.It is an independent risk factor for the death occurred in eiderly patients with chronic disease.The levels of serum NT-proBNP are closely correlated with the survival rates and survival time of elderly patients,It can be used as a monitoring indicator of the elderly patients with chronic disease in risk stratification.

Objective To study the effect of the long-term administration of hemocoagulasein vitro and in vivo,whether it may cause hypofibrinogenemia and changes of cytokine interleukin-6(IL-6) expression level which related to fibrinogen synthesis.Methods Totally 50 healthy subjects pooled plasma was chose in vitro experiments,which was divided into 7 groups.After that,added various of dilutions of injection hemocoagulase and incubated at 37 ℃,detected FIB concentration every 12 h.In vivo experiments,80 rats with six-week old were randomly divided into 4 groups:negative control group,high-dose group,middle-dose group,low-dose group,After 3 weeks administration,the serum level of Ⅴfactor,Ⅷ factor,PT,activated partial thromboplastin time (APTT),FIB,IL-6 was detected.Results Hemocoagulase in vitro had a strong role to reduce fibrin,and showed a significant dose-dependent and time-dependent;Hemocoagulase prolonged low-dose use might reduce the concentration of FIB in mice,but theⅤfactor,Ⅷ factor,PT,APTT,TT were not significantly affected.Compared with the negative control group,FIB and IL-6 concentration decreased in high-dose group,middle-dose group,low-dose group and had statistically significant differences (P<0.05);The level of FIB among the groups had statistically significant differences (P<0.05).The APTT of the middle and high dose groups was slightly prolonged,which was significantly different from that of the negative control group (P<0.05).Conclusion Hemocoagulase has a strong effect to reduce the concentration of fibrin,when there is a long-term medication,fibrin concentration of the patient should be closely monitored,hemocoagulase not only directly decomposed fibrin,but also may affect the synthesis of IL-6,the specific mechanism needs further study.

To analyze the reasons of injuries during surgical practices and explore the hazards and the corresponding preventive measures. The surgical interns don't receive enough training of injury prevention. They don't pay enough attention to the occupational prevention and are not skilled in operation, which causes high rate of sharp edged instrument injuries. Therefore, a perfect plan of education, training and treatment must be made to reduce the occupational injuries and blood sourced diseases.
