Objective: To investigate Leptin resistance of patients with metabolic syndrome. Methods: 50 patients with metabolic syndrome and 30 health persons as control were investigated. Body mass index(BMI)、waist to hip ratio(WHR)、blood pressure(Bp) were recorded. Serum Leptin、plasma glucose、insulin、total cholesterol(TC)、triglyceride(TG)、high density lipoprotein cholesterol(HDL C)、low density lipoprotein cholesterol(LDL C)、lipoprotein(a) were determined,and HOMA IR was calculated. Results: Compared to controls, serum Leptin concentration was significantly higher in metabolic syndrome〔(23.82?15.63)?g/L vs (11.20?4.70)?g/L, P

Objective To explore the relationship between physical activity ( PA) in college students and self?efficacy,and provide guarantee for improving health education in colleges. Methods International physical ac?tivity questionnaire( IPAQ) ,scales of physical behavior,scales of stage of change in physical exercise behavior,and scales of self?efficacy were used to test 504 students from some of colleges in Zhejiang province. Results Signifi?cantly more males (38.52%) than females (27.27%) were in the high activity tertile (P<0.01); the amount of PA per week in males and females were (4608±872.07)MET and(4361±674.03)MET(P<0.01); the scores of males and females were (3.32±0.44) and(3.04±0.36),(P<0.01). The number of males (35.5%) in maintenance period and period of action is greater than that of females (28.9%). Males had higher self?efficacy and more scores of behavior than females (P<0.05) . There were significant characteristics of PA in their self?efficacy,score of be?havior and stages of change( F=18.38, F=15.08, F=34.71, P<0.01),and a significant correlation between PA and self?efficacy,stages of change and physical exercise behavior ( r=0.336, r=0.36, r=0.46, P<0.01).Conclu?sion Self?efficacy may have important effect on the level of PA. Stages of change and scores of behavior may ex?plain difference of PA between males and females.

Ⅳ, change of phosphocreatine (PCr) content was very similar to thatof ATP. Content of ADP, AMP, Cr and HYPO was negatively correlated to ATP content. NAD content was also reduced. In summary, recently proposed hyperkalemic crystalloiddilluted blood protecting myocardium would not be sufficient enough and further improve-ment is quiet neccessary.

Objective To discuss clinical features and surgical treatment of the coexistence of cervical,thoracic and lumber degenerative disease.Methods From January 2004 to December 2008,79 cases with the coexistence of cervical,thoracic and lumber degenerative disease were surgically treated,including 51 males and 28 females,aged from 30 to 80 years(average,58.1 years).All 79 cases presented coexistence of cervical,thoracic and lumbar compression symptoms,such as limb numbness,weakness,zonesthesia and positive Hoffmann and Babinski sign.Forty-one cases mainly presented cervical symptoms,5 presented thoracic symptoms and 12 presented lumbar symptoms.According to affected segments,41 cases received cervical operations,5 cases received thoracic operations,12 cases received lumber operations,and 21 cases received two parts operations.Surgical outcomes were evaluated by Japanese Orthopaedic Association(JOA)score.Results JOA score of all cases improved in varying degrees.The improvement rate of received cervical operation was 66.06%±14.33%,and that of received mere thoracic operation was 56.19%±9.85%,and that of lumbar operation was 63.49%±9.78%.Twenty-one cases received tow parts operations.Forteen cases received one-stage two parts operations with improvement rate of 76.78%±3.94% and 7 cases received twostage two part operations with improvement rate of 71.79%±8.74%.Conclusion The coexistence of cervical,thoracic and lumber degenerative disease is a kind of complex disease,which involves multi-segments and presents various clinical manifestations.The condition was caused by disk herniation,spinal stenosis and ossification of posterior longitudinal ligament and hypertrophy or ossification of ligamentum flavum.The optimal surgical procedures should be selected by integrated judgment of symptoms and imaging manifestations.

Objective: To identify and highly express the L-Methionine ?-lyase gene from Trichomonas vaginalis(TVMGL).Methods: The TVMGL gene was cloned into pGEX 4T-2,the recombinant protein expressed in E.coli DH5?and confirmed by SDS-PAGE.Results: Denaturing SDS-PAGE analysis confirmed the predicted size of the fusion protein(GST-TVMGL,68 000) and showed high purity after subsequent affinity chromatography on Glutathione sepharose 4B.The target proteins amounted to 34% of the total bacteria proteins.Conclusion: The L-Methionine ?-lyase gene was highly expressed in E.coli.

Through exploring the cause of medical students' professional identity status and further analyzing the present misunderstanding that exists in medical students' humanistic education,this paper thoroughly discussed the dialectical relationship between medical humanities education and medical students' professional identity.It analyzed the effects of medical humanistic education on medical students' professional values,professional expectations,professional sense of belonging and how medical humanistic education plays a role in them.

Objective:The aim of this study was to examine whether PSA levels were affected by BMI and the influence of BMI on the clinical application of PSA.Methods:A total of 856 males who had routine health checkups between January 2006 and July 2007 in our hospital were recruited for this study.Those with a documented history of prostate carcinoma were excluded.Height,weight, and total PSA were measured.The BMl was calculated from measured height and weight [BMl=weight(kg)/height(m)2].Results:The serum PSA(ng/mL)levels were 2.97±0.15 in the normal weight group,2.53±0.12 in the overweight group,and 2.01±0.16 in the obese group(P＜0.05).A negative correlation was found between PSA and BMI(r=-0.130,P＜0.05)and weight(r=-0.142.P＜0.05).A positive correlation was found between PSA and age(r=0.306,P＜0.05).Con-clusion:BMl is associated with PSA.As BMI increases, serum PSA decreases.The current data suggest that such an influence should be considered in the clinical application of PSA.

ObjectiveTo study the diagnostic method of microcirculation disturbance of patients with chronic hepatitis B (CHB).Methods81 patients with CHB and 5 normal volunteer were observed.Hypoxia-induciable factor was detected by immunohistochemistry stain,TXB2 and 6-Keto-PGF1α were detected by chemiluminescence and HA was detected by RIA,ultrastructure of liver was observed by transmission electron microscope (TEM).ResultsAccompany with the pathological changes of liver in patients with CHB,the strength and range of expression of HIF-1 α enhanced,HA and TXB2 of serum rised gradually( all P ＜ 0.05 ),but 6-Keto-PGF1α of blood plasma fell- off.The electron microscope showed that erythrocyte aggregation,stenosis and blockage of sinus hepaticus turned obviously,collagen fibers deposition and basal membrane formation aggravated gradually.ConclusionAssociated detec tion with HIF-1 α、HA 、TXB2 and 6-Keto-PGF1 α can reflect the condition of microcirculation of liver perfectly.

Objective To explore the influence of different anesthetics on emergence agitation (EA) after general anesthesia. Methods 134 EA patients after general anesthesia were randomly divided into three groups. Group A (n=42), Group B (n=45) and Group C (n=47) was given intravenously parecoxib 40 mg, butorphanol 20μg/kg and tramadol 1 mg/kg, respectively. The improvement of agitation, VAS score and Ramsay score were compared and analyzed among the groups. Results After treatment, the degree of EA in Group A, Group B was significantly lower than that in Group C ( <0.05) . VAS score in all the cases was reduced, and Ramsay score was increased compared with that before treatment ( <0.05) . VAS score in Group C was significantly higher than that in Group A, Group B (<0.05) . Ramsay score in Group B was significantly higher than that in Group A, Group C (<0.05) . After treatment, awaking time and postanesthesia care unit (PACU) stay in Group B was significantly higher than that in Group A, Group C (<0.05) .Conclusions Parecoxib is safe and effective for EA after general anesthesia, it can effectively improve the degree of EA, increase postoperative sedative effect, and shorten PACU stay.
