Objective To investigate the diagnostic value of biexponential model of DWI in nontypical hippocampal sclerosis (HS) of the youth.Methods DWI with multiple b values were performed on 75 youths with right temporal lobe epilepsy and 20 healthy youths(control group).There were no abnormalities in hippocampus on conventional MRI.11 of 75 patients were proved right HS by surgery and pathology (HS group).Compare the volume of the right hippocampus and their D,D? and f values in HS group and control group.Results There were statistical differences in D and f values between HS group and control group (Z=-3.08,Z=-2.23,P<0.05). There were no statistical differences in the volume of hippocampus and D? values between two groups (Z=1.77,Z=-0.19,P>0.05). Conclusion When HS does not have typical appearances on conventional MRI,D and f values can provide help from diffusion and the perfusion of microcirculation aspects.

Objective To investigate the relationship of D-dimer(DD) and fibrinogen levels in blood plasma and diabetic nephropathy(DN).Methods According to the results of urinary albumin excretion rate (UAER), 98 cases of type 2 diabetas were divided into simple diabetic mellitus ( SDM), early diabetic nephropathy ( EDN) and clinical diabetic nephropathy (CDN); other 45 healthy persons were employed as control. Plasma levels of DD and the fibrinogen of all groups were examined.Results There was significant difference of DD and fibrinogen levels in all groups as compared with control group (P

Lower urinary tract symptoms due to benign prostatic hyperplasia is of great prevalence among ageing males,and it can markedly affect patients' quality of life.Personalized drug therapy according to genetic characteristics is the ideal choice for this problem.Here we summarized the latest research findings on the associations of gene polymorphisms with drug efficacy and adverse reaction in the treatment of benign prostatic hyperplasia/urinary tract symptoms.

Objective:To investigate the relationship between primary and secondary school teachers' occupational burnout and mental health.Methods: Maslach questionaiers about occupational burnout and mental (MBI) and SCL-90 were administrated to 528 primary and secondary school teachers. Results: (1) Correlation analysis showed significantly positive correlation between primary and secondary school teachers' occupational burnout and mental health. Emotional Exhaustion related highest to somatization, compulsion, interpersonal relation, depression, anxiety, hostility, and paranoid. (2) Stepwise regression analysis revealed that the three dimensions of professional burnout predict significantly mental health, Emotional Exhaustion accounted most for the variance.Conclusion:Teachers occupational burnout is correlated with mental health. Different occupational burnout dimensions can all predict mental health.

Objective To summarize the experience on bronchiallavage to cure pulmonary atelectasis and pulmonary infection after thoracotomy.Methods 48 patients were selected and treated by bronchiallavage under monitoring,and antibiotics was used according to sputum culture and drug sensitive test.The out come was analyzed and evaluated.Results All patients of the pulmonary atelectasis were cured and those with pulmonary infection were controled.There was no serious complication.Conclusion Bronchiallavage is applied to treat pulmonary atelectasis and pulmonary infection after thoracotomy,the curative rate is significant.The appliance of antibiotics is guided by drug sensitivity.It is such a safe and feasible therapeutic tool that the bronchofibroscope is applied to cure pulmonary atelectasis and pulmonary infection after thoracotomy.

Objective To determine the contents of lutein,zeaxanthin and ?-carotene in 31 vegetables.Method High performance liquid chromatography method with Develosil C30 column and ultraviolet detector was used to detect lutein,zeaxanthin and ?-carotene at wavelength of 480nm.A gradient elution method with elution A (acetonitrile:methol=75:25) and B (methyl-tert-butyl-ether) was used to separate the carotenoids in both raw and cooked vegetables.Results The retention time of lutein,zeaxanthin and ?-carotene was 10.355,10.732 and 20.789 min respectively.The contents of lutein,zeaxanthin and ?-carotene were linearly related with the peak area.Analysis showed that dark leafy vegetable such as amaranth,Chinese celery leaf,parsley,spinach and pakchoi petiole contained the highest amount of lutein.Zeaxanthin was detected only in dehydrated daylily.There was little or no loss of lutein,zeaxanthin and ?-carotene but an average increase in lutein and ?-carotene in vegetables after cooking.Conclusion Vegetables,especially dark leafy vegetables are major sources of dietary lutein,and ?-carotene.Consuming cooked vegetables tends to increase the intakes of lutein,zeaxanthin and their bioavailability.

Objective To investigate the receptor involved in the TNF?induced HO-1 expression and the related signal transduction mechanisms in the brain microvessel endothelial cells.Methods TNF? receptor 1(TNFR1)knockout murine brain microvessel endothelial cells(BMVECs)in vitro culture were stimulated respectively by TNF?(5ng/ml).After 24 hours,the level of HO-1 gene mRNA were detected by semi-quantitative RT-PCR,the effect of TNF?on JNK 、ERK or transcription factor AP-1 were analyzed by Western blot,while ERK inhibitor(PD98059)or JNK inhibitor(SP600125)were used.Results Exposure of wild-type BMVECs and TNFR1(p55)knockout BMVECs [BVEC/TNF-RI(-/-)] to TNF?(5ng/ml,24 h)caused a marked increase in HO-1 mRNA expression.Furthermore,TNF? stimulation also lead to the activation of JNK,ERK and the transcription factor AP-1 in the BVEC/TNF-RI(-/-),However,incubation with the JNK inhibitor SP600125 but not the ERK inhibitor PD98095 attenuated the TNF?-induction of HO-1 in the BVEC/TNF-RI(-/-).Conclusions TNFR2 and JNK activation but not TNFR1 might be essential for mediating the TNF?-induction of the HO-1 in the endothelial cells.

The membrane fluidity of mitochondria isolated from langendorff perfused rat hearts was studied with ESR spin labeling technique and TBA method was used to detect the content of lipid peroxide. After total ischemia for 40min followed by a 20min reperfusion the 10-DSA region of the mitochondrial membrane showed significantly increased S (0.1(?)2?0.006) and ?_c(7.13?0.09?10~(10)sec) values (i. e. a decrease of membrane fluidity)in comparison with aerobic control (S=0.103?0.007); ?_c=6.86?0.20?10~(-10) sec) (P0.05). In addition, we found that DS182 could remove O_2~? produced by O_2~? generating system. Our results have showed that DS-182 is a potent scavenger of superoxide. The protective effect of DS-182 on mitochondria during ischemia/reperfusion might be due to its antioxidative activity。

This study was performed on rabbits to examine the changes of calmodulin (CAM) and cAMP in the myocardium during ischemia and reperfusion by radioimmunoassay method. The result showed the levels of CaM and cAMP increased at 20 min of ischemia. Although these two parmeters were unchanged at 40 min of ischemia as compared with the changes at 20 min, they were changed during reperfusion at different times of ischemia. At 20 min ischemia following 10 min reperfusion, the content of CaM decreased, the content of cAMP increased. On the basis of 40 min ischemia, reperfusion induced opposite changes: CaM increased, cAMP decreased. The possible mechanism of these changes was discussed.
