Objective To evaluate odds ratio(OR)of common risk factors and independent risk factors of stroke in elderly male.MethodsOutpatients and inpatients from hospital who aged≥65 year and male were enlisted in the study.Patients diagnosed as stroke were defined as case group and without history of stroke were defined as control group.A uniform questionnaire was designed for investigate general information and common risk factors of stroke.Odds ratio of risk factors were estimated by a case-control design and Multiple Logistic regression was applied to define independent risk factor.ResultsUnivariate analysis indicated that systolic,diastolic,mean blood pressure,weight,body mass index(BMI)in case group were significantly higher than that in control group.Hypertension,heart disease,diabetes,obesity,cigarette smoking and alcohol drink were the statistically significant risk factors of stroke.Ors of these risk factors were 2.26,1.57,2.57,1.96,1.49 and 1.54,respectively.Multiple Lgistic regression analysis showed that cigarette smoking,diabetes,obesity and hypertension were the factors being selected into equation.ConclusionCigarette smoking,diabetes,obesity and hypertension were the independent risk factors of stroke in elderly male.

Objective To investigate the amide proton transfer (APT) values in basal ganglia of neonatal piglet hypoxicischemic brain injury (HIBI) model using MR APT imaging.Methods Totally 35 healthy neonatal piglets were selected.There were 5 piglets underwent sham-operation in control group and 30 piglets used to established HIBI models in HIBI group.According to the time interval between APT imaging and the establishment of HIBI model,the piglets in HIBI group were divided into 0-＜2 h,2-＜6 h,6-＜12 h,12-＜24 h,24-＜48 h and 48-＜72 h subgroups.APT imaging was performed on all piglets.The APT value of basal ganglia between control group and all the subgroups in HIBI group were compared.Results After HIBI occurred,the APT values immediately decreased in 0-2 h,and then increased gradually.In 24 h after HIBI,the APT values were mainly returned to the level of control group,then continuously increased.The APT value in control group and 0-＜2 h,2 ＜6 h,6 ＜12 h,12-＜24 h,24-＜48 h,48-＜72 h subgroups in HIBI group were 0.52 ± 0.09,-0.35 ± 0.08,-0.02 ± 0.14,0.28± 0.04,0.46 ± 0.11,0.80 ± 0.11,1.24 ± 0.18,respectively.The APT values between control group and each subgroups in HIBI group had significant differences (all P＜0.01) except for 12-＜24 h subgroup (P=0.68).Conclusion The APT value decreased firstly and then increased after HIBI in neonatal piglet.APT imaging can provide a non-invasive molecular MR method to evaluate the pathophysiological changes of HIBI.

Objective To detect TCRγ gene rearrangements in skin lesions and peripheral blood of patients with parapsoriasis, and to study their clinical significance. Methods Totally, 20 patients with parapsoriasis were included in this study. BIOMED?2 multiplex PCR was performed to detect TCRγgene rearrangements in lesional skin (n=20)and peripheral blood(n=11)samples from the patients with parapsoriasis. Statistical analysis was performed to assess the relationship of TCRγ gene rearrangements with clinical types of parapsoriasis as well as general information and histopathological manifestations(including non?specific manifestations and atypical manifestations)of patients. Results TCRγ gene rearrangements were positive in lesional skin from 7 of the 20 patients, in peripheral blood from 3 of 11 patients, and in both lesional skin and peripheral blood from 2 patients. Positive TCRγ gene rearrangements in skin lesions were significantly correlated with mycosis fungoides(MF)?related atypical histopatho?logical manifestations(P<0.05), but those in neither skin lesions nor peripheral blood were correlated with gender and age of patients or clinical course and types of parapsoriasis(all P>0.05). During an average follow?up time of 44.85 ± 18.48 months, 1 case progressed into MF, and 2 were cured. Conclusions Positive TCRγgene rearrangements in skin lesions of patients with parapsoriasis may be correlated with MF?related atypical manifestations. The presence of TCRγgene rearrangements and atypical histopathological manifestations may suggest the possibility of progression from parapsoriasis into MF.

Objective To study the results of treatment of open fracture of tibia and fibula by external fixation with unilateral multifunction external fixation apparatus(UMEFA) and plaster in different period. Methods 89 cases with open fracture of tibia and fibula had got reduction and external fixation with UMEFA and then divided into two groups, group A of 53 cases followed by external fixation with UMEFA, 8 cases of them were forced to remove UMEFA because of complications, the other 45 cases followed by external fixation with UMEFA till bone union, group B of 36 cases were removed UMEFA and changed with plaster when the skin was healed, the sweal was eliminated and the bone was steady. Compared and analyzed the results by complication, healing time and quality.Results In group B, there was less complications(P

Objective The application value of CTA for BA in interventional theray of lung cancer.Methods 15 patients with lung cancers including central type(13 cases)and peripheral type(2 cases) proven by pathology were analyzed prospectively.They were all examined with contrast enhanced.MDCT and the data were sent to the workstation and reconstructed with thin section multi-planar reformation(MPR),maximum intensity projection(MIP)and volume rendering(VR).Results All cases of central type lung cancer were supplied by the bronchial artery including two by the bronchial artery and intercostal artery,clearly demonstrated on the scans with the origin,branches and routes.One case of peripheral lung cancer was supplied by the bronchial artery and the other could not find the definite supplying artery.Conclusions CTA of BA for lung cancer can provide the accurate localization and other reference data for interventional therapy.

AIM: To explore the relationship between methylation status of promoter region 5′CpG island and the biological phenotype in human colorectal cancer RKO cell lines. METHODS: RKO cells were treated with selective DNA methyltransferase (DNMTs) inhibitor, 5-Aza-2′-deoxycytidine (5-Aza-CdR), for 72 h. Methylation-specific PCR (MSP), T-A clone and DNA sequence analysis were used to detect 5′CpG island methylation status of p16/CDKN2 tumor suppresor gene. Cell growth, cell cycle arrest and apoptosis were analyzed by MTT, flow cytometry (FCM), fluorescent dye staining and transmission electron microscope. RESULTS: DNMTs inhibitor (5-Aza-CdR) effectively reversed the hypermethylation status of 5′CpG island. The effects of 5-Aza-CdR on cell growth inhibition (P
