The empirical study was carried out over 276 from medical students with EOM-EIS-2 and General Well-Being Schedule as instruments.The data collected were analyzed statistieally by SPSS17.0.Results suggest that:there are no phenomenal grade differences in relation to self-identity,ideology and interpersonal relationship;the gender differences exist in relation to self-identity,ideology and interpersonal relationship;there ale no significant grade and gender differences in subjective well-being;there are correlations between some sorts of self-identity and subjective well-being.

One-day-old unvaccinated chicks were inoculated with serotype I virulent strain GA and vaccine strain CVI988, serotype III vaccine strain HVT o f Marek's disease viruses(MDV). By using an indirect immunofluorescence assay of suspensions of peripheral blood mononuclear cells(PBMC) with monoclonal antibo dies(MAb) BA4 and BD8 specific to glycoprotein B of MDV, The dynamic course s of vir emia levels for each of 3 strains from 4 days to 45 days postinfection (PI) were determind. Viremia for virulent strain GA-infected chickens were detected from 4 days PI until days before death of infected chickens, it got its peak at abou t 14 days PI. Viremia in serotype 1 vaccine CVI988-inoculated chickens were mea sured between 4 to 22 days PI, it could be detected from 4 days PI and ended at 18 days PI, it got its peak at 8 days PI. For serotype 3 vaccine HVT-inoculated chickens, viremia could be detected beween 4 to 14 days PI, its peak happened a t about 6 days PI. Such IFA with MAbs BA4 and BD8 could be used to evaluate qu al ity of vaccination process in chicken flocks. The differential dynamic courses o f viremia for different strains may be used to diagnose virulent MDV infection i n vaccinated flocks. The viremia levels measured by IFA with the MAbs and co-cu ltivation assay for plague forming unit(PFU) were compared. The results indicate d that IFA assay of PBMC suspension was more sensitive and specific than co-cu ltivation assay, i.e. viremia levels measured by IFA were 30 to 100-fold higher than that by plague-forming assay in CEF for the same sample.

Objective To explore the effects of combined exercise program ( fun game + rope skip-ping + figure running) on executive function ( EF) in primary students with Chinese learning difficulties. Methods Fifty-four Chinese learning disabled students were selected and randomly divided into experimen-tal group and control group. Three tasks ( the Flanker task,the 1-back task and the More-odd shifting task) were used to measure pupil’ s EF ( inhibition,updating,shifting) . Results ( 1) Compared with the control group,the primary students with Chinese learning difficulties in experimental group showed a significant en-hancement in executive function (F(1,43)=9.45, P<0.01). (2) The positive effects of 10 weeks combined ex-ercise program on executive function in primary students with Chinese learning difficulties were different. Specifically,a beneficial effect on updating(F(1,43)= 11.37, P<0.01) was got,but there were no significant effects on inhibition (F(1,43)=1.52, P>0.05) and shifting(F(1,43)=2.57, P>0.05). Conclusion The effect of combined exercise program ( fun game+rope skipping+figure running) plays a positive role in promoting updating function of primary school students with Chinese learning difficulties.

ObjectiveTo observe the protective effects of Chinese medicine Naoshuning on neurological deficits following traumatic brain injury (TBI) in rats.MethodsCerebral contusion was produced by dropping weight,the beam-walking task was employed to observe neurological functional changes,water content in the brain tissue and neuropathological changes were also evaluated.ResultsWithin one week the ability to process in beam-walking task was significantly lessened,the outcome of beam-walking task of Naoshuning group was significantly better than that of the model group.Water content in the brain tissue and neuropathological changes were also alleviated in Naoshuning group compared with that in model group.ConclusionEarly alleviating brain edema,protecting brain tissue may be one of the mechanism of Chinese medicine to ameliorate the behavior deficits following TBI in rats.

ObjectiveTo investigate the dynamic change of cerebral aquaporin 4 (AQP4) expression level during traumatic brain injury (TBI) in rats and the relationship between AQP4 expression and traumatic brain injury and edema. MethodsThe experimental TBI model was established by bumpiness of free falling body according to Feeney's. The changes of brain water content (BWC) and permeability of blood-brain barrier (BBB) were measured by the methods of wet and dry weight and Evans blue fluorometry. Immunohistochemistry was used to determine the change of expression of AQP4 during different periods after TBI. Results6 h after TBI, water content of brain tissue and EB content in the contusion side significantly increased, and the protein expression of AQP4 in contusion marginal region began to increase. They reached summit 24 h after operation and did not come back normal level 5 d after operation. There was significantly positive correlation between protein expression of AQP4 and change of EB content (r=0.957486,P<0.05). ConclusionThe dynamic change of cerebral AQP4 expression level closely related to the destruction of BBB and the formation of cerebral edema during traumatic brain injury.

Objective To evaluate pressure-flow study in assessment of dysuresia symptom in elderly male patients. Methods A total of 125 elderly male patients with dysuresia and prostatic enlargement underwent urodynamic examination.Their age ranged from 56 to 83 years with a mean of 68 years.If the patients urinated smoothly with satisfying urinary flow curve,the pressure-flow study would be performed on them.According to the results,the patients were classified as 3 groups:BOO,equivocal BOO and non-BOO groups.Their detrusor contractive function was classified as strong,normal,weak or very weak. Results Of the 125 patients undergoing urodynamic test,87 obtained definite pressure-flow study findings.Of the 87 patients,39 were with BOO,18 with equivocal BOO and 30 without BOO.In the BOO,equivocal BOO and non-BOO groups,detrusor pressure at maximum flow was (99.2?34.3) cmH 2O (1cmH 2O=0.098 kPa),(46.9?9.9)cmH 2O and (30.8?10.0)cmH 2O,respectively;intravesical opening pressure was (99.4?39.6) cmH 2O, (43.7?9.9) cmH 2O and (29.9?9.7) cmH 2O, respectively; minimum voiding detrusor pressure was (61.3?27.5) cmH 2O, (33.9?14.1)cmH 2O and (22.1?12.5)cmH 2O,respectively;and maximum detrusor pressure was (113.0?42.1)cmH 2O,(55.8?14.9)cmH 2O and (38.4?11.3)cmH 2O,respectively.The detrusor function was normal or strong in 74.4% (29/39) of patients with BOO,27.8%(5/18) of patients with equivocal BOO and 26.7% (8/30) of patients without BOO.All these parameters of the BOO group were higher than those of the equivocal BOO group and non-BOO group (both P

Objective To evaluate the bladder functions by urodynamic studies in diabetic patients with lower urinary tract symptoms (LUTS). Methods Urodynamic studies were performed in 42 diabetic patients (24 men and 18 women;age range,38-78 years).The diabetic history of the patients was from 1 month to 25 years. Results Of the 41 cases who underwent all items of urodynamic examination,38 cases (93%) had abnormal findings and 3 (7%),normal.The detrusor was underactive in 14 cases (34%) and areflexia in 10 (24%);BOO was found in 13 (32%).One female patient had stress urinary incontinence. Conclusions There is a high prevalence of bladder dysfunction in diabetic patients with LUTS.It is necessary to perform urodynamic studies in diabetic patients before initiation of therapy,especially in patients who are assigned to undergo bladder and urethral surgery.Preoperative urodynamic studies can contribute to the surgical success rate.
