The patients body mass, body fat rate, waist circumference, serum lipid, blood glucose, blood pressure and adverse effects were determined 12,24 and 48 weeks after withdrawal of sibutramine. Results: There were no significant differences in body mass,body mass index, body fat rate and waist circumference between sibutramine group and placebo group 48 weeks after withdrawal of sibutramine. For sibutramine group,there was no obvious difference before and after treatment, but there was significant difference between immediately and 48 weeks after withdrawal of sibutramine (P

Objective:To study the expression of vascular endothelial growth factor (VEGF) and VEGF mRNA after focal cerebral ischemia reperfusion in rats.Methods:MCAO (Middle Cerebral Artery Occlusion) models were set up in rats,and the rats were divided into six groups:control group,5 groups of ischemia for 2h then respective reperfusion for 6h,12h,24h,48h and 72h.The samples were analyzed with immunohistochemical methods.The expression of VEGF mRNA was detected by RT-PCR analysis.Results:VEGF protein expression started at 6h.It increased remarkably at 24h,and it was strongest at 48h.VEGF mRNA increased at 6h,while reached peak value at 12h and reduced at 24h,finally returned to normal level at 48-72h.VEGF expression was mainly detected in the periphery of infarcts at every timepoint.Conclusion:These findings demonstrate that the VEGF strong expression can be induced in focal cerebral ischemia reperfusion in vivo.The changes of VEGF levels suggest that VEGF has neuroprotective effect against cerebral ischemic injury.

Polycystic ovary syndrome (PCOS)is the most common cause of anovulatory infertility in women of reproductive age, exerting significant impacts on glucose and lipid metabolism, cardiovascular and endometrial deseases, as well as breast, skin, bone, and psychology fields. As a complex, multi-system of endocrine and metabolic disease, PCOS would be recognized as a component of metabolic syndrome in an overall consideration. The clinical treatment of PCOS is expected to turn simply regulating menstruation and ovulation adjustment into the combination of insulin resistance improvement with antihyperandrogen and ovulation treatment comprehensively.

There is a strong support for a role played by adiponectin in the function of ovary and placenta.There is evidence of direct effects of adiponectin on the late stages of folliculogenesis,and additive interactions of adiponectin with insulin and gonadotropins in inducing periovulatory changes in ovarian follicles.Adiponectin has demonstrated a potential effect on ovarian function as well as a possible effect on the formation of placenta,via multiple mechanisms,providing new strategies for the etiology investigation,prevention and treatment of reproductive and related metabolic diseases.

Objective To explore the clinical effect of different operative methods in the treatment of papillary thyroid carcinoma.Methods Using random number method according to the proportion of 1∶1,95 patients with papillary thyroid carcinoma were divided into observation group(n=48) and control group(n=47).The control group was treated by ipsilateral lobectomy and isthmus resection and ipsilateral central lymph node dissection,the observation group was treated by total thyroidectomy plus ipsilateral central lymph node dissection.The tumor size,lymph node involvement,the score of KPS,the surgical complications and the rate of postoperative recurrence and metastasis of the two groups were compared.Results The tumor size,lymph node involvement and surgical complications in the observation group had no statistically significant differences compared with the control group(t=-1.367,P=0.175;t=-1.495,P=0.138;x2=1.642,P=0.232).After treatment,the effective rate of KPS score in the observation group was 81.25%,which was higher than 72.34% in the control group(Z=-3.639,P=0.000).The observation group had no recurrence,which was lower than 5 cases in the control group,the difference between the two groups was statistically significant(x2=5.390,P=0.006).The observation group found 1 case of metastatic patient,which was lower than 7 cases in the control group,the difference between the two groups was statistically significant(x2=5.053,P=0.031).Conclusion Total thyroidectomy plus ipsilateral central lymph node dissection in the treatment of papillary thyroid carcinoma has significant clinical curative effect.It can effectively reduce the risk of tumor recurrence and metastasis and improve the quality of life of patients.It is worthy of popularization and application.

One especial surgical technique recently was named chromovitrectomy.Vital dyes or crystals should be applied during surgery to improve the visualization of intraocular tissues and to simplify specific procedures such as internal limiting membrane (1LM) peeling,etc..Ttriamcinolone acetonide (TA),indocyanine green,trypan blue,bright blue,etc.are the most popular dyes in chromovitrectomy nowadays.Since the basic characteristics and dyeing properties of these dyes vary,the application range is of distinguishing each.This article aimed to introduce the clinical application characteristics,toxicity/adverse effect of the vital dyes,and summarize the development of these drugs.

BACKGROUND:The driving strength may be an undiscovered power source with a great developing potential. To clarify the relationship between driving strength and lower limb strength is of great importance to the development of the theory of human movement science.OBJECTIVE: To find out the relationship between the maximal driving strength and the maximal lower limb strength.DESIGN: Observation and contrast analysis.SETTING: Department of Physical Education, Ocean University of China.PARTICIPANTS: A total of 94 male healthy university student athletes were enrolled from Ocean University of China between December 2000 and November 2001, aged (19.7±1.7) years and weighed (75.27±2.93) kg. All the objects that had never used the hip stress strengthtraining apparatus took part in theexperiment voluntarily.METHODS: Forty-six of 94 subjects were randomly selected to take part in an 11-month program of driving strength improvement by using hip stress lower limb strength training apparatus (far fixed hip-stressed lower-limb strength training apparatus and near fixed hip-stressed lower-limb strength training apparatus were manufactured by Ocean University of China, pattern number: HNLPT-04Ed, HNLPT-04E respectively). And other 48 subjects were arranged as the control group using current strength training methods (resistance forward leg extending and barbell squatting). For experimental group to do strength practice and measurement, the object sat on the hip-supporting seat straightly, pressed his hip against the hip-stressed resistant unit and put his feet on the pedals, then extended leg at the preset angle and locus.When the near fixed device was used, the trainee kept his hip and body trunk in a static position, and drove the pedals backward. When the far fixed device was used, the pedals fixed in a static position, the hip and trunk were pushedforeword by legs. ① Multifunction strength training apparatus and far fixed hip stress lower limb strength training apparatus were respectively used to test the maximal lower limb strength and maximal driving strength of 94 objects.② Comparisons between before and after training in two groups were made in the maximal driving strength and the maximal low limb strength.MAIN OUTCOME MEASURES: The maximal leg strength and leg driving strength of 94 healthy subjects before and after training.RESULTS: All the 46 subjects in experiment group and the 48 subjects in control group were involved in the result analysis.①The maximal driving strength was lower than the maximal leg strength [(1 135.53±196.98) N, (2 414.62± 424.05) N, P ＜ 0.01].②After the 11-month special training with hip stress lower limb strength training apparatus, the maximal driving strength of experiment group got a significant increase [(1 124.94±206.19), (1 762.24±193.45) N, P ＜0.01]. No significant differences were found in the control group.CONCLUSION: The increase of driving strength from the hip stress lower limb strength training may be an increase of athletic capability that can never be achieved by any current strength training method and apparatus. The application of this method will make it possible to realize great breakthrough of world sports records in the events of running and jumping.
