Objective:To evaluate the current situation and the developing trend of 5-HT3 receptor antagonists used in 25 hospital of Wuhan during the period of 2003～2005 in order to provide reference for clinical doctors and pharmacists. Method:The 5-HT3 receptor antagonists were statistically analyzed in respect to the purchase sum of money,DDDs and daily costs. Result:During the 3 years, purchase sum of money of 5-HT3 receptor antagonists were yearly increasing. The share of the market of domestic drugs showed an increasing tendency,while the imported drugs decreased year by year. Granisetron, ondansetron and tropisetron were much more frequently used than others. Conclusion:The market of the oral agents of 5-HT3 receptor antagonists will further expand in China.

Objective To explore the causes of misdiagnose of ectopic pregnancy by retrospective analysis in our hospital cases,in order to increase the diagnose and curative level in ectopic pregnancy.Methods Clinical data of the misdiagnosis of 96 cases from the 357 patients of ectopic pregnancy in our hospital from year 1993 to 2002,including materials of histories ,symptoms signs and laboratory examinations were retrospectively analyzed.Results The misdiagnosis rate of ectopic pregnancy in our hospital was 26 9%, most of them were treated as early pregnancies, threatened abortions etc. The causes of misdiagnosis were neglectful of asking essential history, no overall physical examination and misleading by the laboratory results.Conclusions The effectively preventive measures against misdiagnosing of ectopic pregnancy were strengthen vigilance of ectopic pregnancy,familiar with the knowledge of atypical ectopic pregnancy and the essential examinations on gravida.

BACKGROUND:The ligamentum flavum is important to connect the rear of the spine. If the flexibility of the ligamentum flavum is decreased due to degeneration, in the role of various factors, it can reduce the effective space of the spinal canal to induce spinal cord and nerve root compression, thereby resulting in neurological symptoms, even paralysis or residual disease. OBJECTIVE:To study the mechanism of over-dose fluoride on the degeneration and ossification of the ligamentum flavum in rats. METHODS:Thirty male Sprague-Dawley rats were randomly divided into two groups: experimental group was given distiled water containing NaF (mass fraction 10-4) and control group was given the same amount of distiled water. After 3 and 6 months, the bone mineral density, Ca2+ and P3+ contents in serum and bone tissue and serum alkaline phosphatase activity were detected, respectively. Meanwhile, the ligamentum flavum specimens were taken for X-ray examination and histopathological observation. RESULTS AND CONCLUSION: In the experimental group, chalk stripes or spots occurred in the lower incisors of five rats at 3 months after treatment and dental fluorosis that was mostly in chalk color was found in al the rats at 6 months after treatment; moreover, the bone density of the lumbar spine significantly increased (P < 0.05). Compared with the control group, the contents of serum Ca2+ were significantly higher, while the contents of P3+were significantly lower in the experimental group at 3 and 6 months after treatment (P < 0.05); the serum alkaline phosphatase activity was also significantly higher in the experimental group than the control group at 3 and 6 months after treatment (P < 0.05). X-ray films, at 6 months after treatment, showed that the bone density of the lumbar vertebra was increased obviously; pathological observation showed that the number of elastic fibers in the ligamentum flavum was reduced further, a large amount of colagen fibers, fibroblasts and calcium deposition were found, and the ossification of the ligamentum flavum was visible at the lamina attachment site. These findings indicate that the over-dose fluorides can lead to the degeneration and ossification of the ligamentum flavum in Sprague-Dawley rats, which may plan an important role in the ossification of the ligamentum flavum.

As our country lack professionals of public health,higher demand to the preventive medicine is further made with the transformation of medical model and the construction of the public health system,and the reformation in preventive medicine education of higher learning is explored to cultivate the practical professionals of public health by modulating education program and courses,modifying the cultivating plan,emphasizing the knowledge of liberal arts and management,strengthening the cultivation of ability and combining theory with practice.

Objective To investigate the effects of long term exposure of 18F-FDG-PET/CT X-rays on rabbit immune system.Methods The rabbits were irradiated with 18F-FDG-PET/CT every day and this irradiation treatment continued for 3 months.At each month,the total number of white blood cells,thymus index and spleen index,phagocytic index,immune globulins,TNF-α and IL-1 in peripheral blood and serum were detected.Results After long-term 18F-FDG-PET/CT irradiation,the total number of white blood cells increased,the thymus and spleen index decreased (t =3.144-72.903,P ＜ 0.05),the phagocytic index and phagocytic percentage decreased after 1 or 2 months(t =2.719-11.859,P ＜ 0.05),and the number of immune cells marked with CD4 + increased but CD8 + decreased(t =6.433-29.877,P ＜ 0.05).In addition,the level of immune globulin in the serum decreased,but the expressions of TNF-α and IL-1β increased (t =2.720-28.775,P ＜ 0.05).Conclusions 18F-FDG-PET/CT has some damage effects on the immune system of male Japanese big ear rabbit,suggesting that the negative effects of PET-CT should be paid close attention to during clinical application.

Objective To assess the clinical effect of Novonorm on treating type 2 diabetic patients with atherosclerosis. Methods Sixty-five patients of type 2 diabetes with atherosclerosis were randomly divided into 2 groups :36 patients took Novonorm,and the other 29 individuals were treated with Glipizide. The blood glucose and CIMT were compared before and after treatment for 12 months. Results The postprandial blood glucose decreased by(1.99 ± 1.06)mmol/L after the treatment of Novonorm,which was significantly higher than that of(0. 99 ±0. 54)mmol/L after the treatment of Glipizide(P ＜ 0. 05). CIMT significantly decreased from (1.11 ± 0. 07)mm before treatment to(1.02 ± 0. 08)mm after treatment in the Novonorm group(P ＜ 0. 05),whereas CIMT were similar between after and before treatment in the Glipizide group(1.07 ± 0. 06)mm vs.(1.10 ± 0. 08)mm(P ＞ 0. 05).Conclusions Novonorm is a kind of effective and safe regent,which can be used to treat type 2 diabetic patients with atherosclerosis.

Objective To evaluate therapeutic effect and safety of hysteroscope operation in treating hysteromyoma. Methods 146 patients were subjected to transcervical resection of myoma (TCRM), curative effects were evaluated as satisfaction or dis-satisfaction according to the degree of bleeding control, the rate of growth of myoma and the need of subsequent surgery. Results The total satisfactory rate is 95%. and satisfactory rate of type 0 and Ⅰ reached 100%. There was no complication in all patients. Conclusion TCRM is the best choice in treating submucous myoma. The results of surgery were satisfactory to intramural myoma if gasp the indictions. Selecting proper indications for operation, B ultrasonic monitoring severity are important for ensuring the operation effect and safety.
