Objective:To study the cognitive features of text anxiety. Methods: The cognitive features of text anxiety were explored by exploratory factor analysis and confirmatory factor analysis on the basis of interview,questionnaire surveying and criterion.Results:There were 6 cognitive factors leading to test anxiety: self-test, worrying, magnifying conclusion, resistance, preparing, self-efficacy.Conclusion: The 6 factors of cognition about text are related to text anxiety

Objective: To explore the differences between the internal social adaptation and external social behaviors of freshmen. Methods: Make a survey of 198 freshmen on the internal adaptation and external by General Well-Being Schedule and Undergraduate Social Adaptation Questionnaires. Results:Freshmen' social adaptation mainly involves three factors: interpersonal communication, the state of campus life and performance of studies. The Cronbach alpha of 3 factors were 0.82, 0.87 and 0.90,and the re-test reliability was r=0.73 (P

Objective:To investigate the effects of oxymatrine(OM)on the apoptosis of human hepatoma HepG2 cells and its possible mechanisms.Methods:HepG2 cells were treated with different concentrations of OM.The proliferation inhibition was measured by MTT assay and the apoptosis of HepG2 cells were examined by Hochest staining method.Flow cytometry was used to analyze the cell cycle distribution and apoptosis rate.The expression of caspase-3,Bcl-2,Bcl-x_L and Bax proteins was assayed by Western blotting assay.Results:OM inhibited HepG2 cells growth in a time-and dose-dependent manner.After treatment with OM for 24 hours,some cells appeared typical apoptotic characteristics and the apoptosis rate was increased. Treatment with OM also increased caspase-3 activity and Bax expression in HepG2 cells,and decreased the expression levels of Bcl-2 and Bcl-x_L.Conclusion:OM can induce HepG2 cell apoptosis,which may be related to the down-regulation of PI3K/Akt signal pathway,suppression of Bcl-2 and Bcl-x_L activity,and activation of caspase-3.

Objective To investigate the effect of underwater treadmill training (UWTT) on patients with hemiplegia after stroke. Methods Based on routine rehabilitation, 15 hemiplegic patients after stroke were treated with UWTT system 20 min/d, 5 times a week for 4 weeks. Walking distance and speed in water were tested before and after UWTT. Dynamic balance function and static balance function were also assessed by Active Balancer assessment. Results All the items improved significantly after treatment (P<0.01), except deflection center displacement of X and Y axis (P>0.05). Conclusion UWTT can improve the walking ability and balance function of hemiplegic patients after stroke.

Objective To explore the efficacy of excision of pterygium combined with fresh amniotic membrane transplantation for treatment of recurrent pterygium.Methods Pteryga of 27 patients(32 eyes) were excised and transplanted with fresh amniotic membrane.Patients were followed up for 6～36 months.Results Pterygium recurred in only 2 eyes during the period of follow-up.The curative rate of the operation for recurrent pterygium was 93.75%,and the recurrence rate was 6.25%.Conclusion Excision of pterygium combined with fresh amniotic membrane transplantation is an effective therapeutic method for recurrent pterygium.

Objective To investigate the method and value of adjustable interatrial fistulization in the operation of congenital heart disease(CHD) accompany with severe pulmonary arterial hypertension(PH).Methods Twenty-seven patients(19 male,8 females) accompany with severe PH were entered the study,age ranged from 4 to 14 years old,weight from 13.7 to 42.0 kilogram.The enrolled diseases included 11 cases of atrial septal defect(ASD),10 cases of ventricular septal defect(VSD),4 cases of patent ductus arteriosus(PDA),and 2 cases of Ebstein syndrome accompany with severe tricuspid insufficiency.All patients were diagnosed as CHD accompany with severe PH(bidirectional shunt)which was the contraindications for routine operation before operation through chest X-ray,electrocardiography,ultrasonic cardiography,cardiac catheteri-zation and cardiac angiography.Results With adjustable interatrial fistulization and treatment to the abnormalities,14 fistulaes were closed immediately after operation,7 fistulaes were closed 2 days after operation,3 fistulaes were closed 3 days and 1 fistulae was closed 4 days after operation and accompanied with empyema discharged initiatively.One fistula was never closed,1 case died from low cardiac output symptom.The effective rate was 92.6%,closed to that of routine operations.Conclusion Adjustable interatrial fistulization is an easy procedure,and it can decrease the danger of PH post-operation effectively and provide operation opportunity for those patients with CHD approaching terminal stage.

Objective To investigate the effect of calcium antagonist verapamil on the function of rat?- cells and tolbutamide (D860)-induced insulin release.Methods Insulin released from isolated islets were measured in control,verapamil,D860,and verapamil+D860 groups.Furthermore,intravenous glucose tolerance test (IVGTT) was conducted in acute experiments treated with verapamil and D860 respectively to assess?-cell function in rats with the same allocation as in vitro.Another IVGTT was performed in the end of 4 weeks' treatment.The insulin contents in pancreas were assayed and pancreas islets morphology were observed with immunohistochemistry.Results Verapamil could inhibit insulin release from isolated islets.Verapamil group was [(1.244?0.082)ng?ml~(-1)?islet~(-1)]and control group (2.623?0.226) ng?ml~(-1)?islet~(-1)(P0.05).Also,similar results were obtained in normal rats during acute experiments and verapamil reduce the hypoglycemic effect promoted by D860. However,above results were not observed in the end of 4 weeks experiments,and no difference for insulin content and morphological change in islets was found among four groups.Conclusion Treatment of verapamil chronically does not impair islet function and interfere with the hypoglycemic effect of D860 in rats .

·Diabetic Retinopathy ( DR ) has gradually worsening and lingering, which is the leading cause of global young people blindness. With the progression of the disease, patients with diabetes mellitus ( DM) will have different degrees of DR. If you can not prevent and give acute early intervention, once the visual acuity decreased significantly, DR would be difficult to reverse. DR progressively has worsening, the treatment status has no optimistic. Therefore, DR in the early prevention and treatment will be indispensable. This article summarizes some of the early warning of the occurrence and development of biological markers and characteristic indicators in order to provide a basis for the early prevention of DR.
