Objective To evaluate the correlation between serum uric acid with cognitive disorder after acute cere?bral infarction by prospective study. Methods Four hundred consecutively enrolled patients of acute cerebral infarction were divided into no cognitive impairment group and cognitive impairment group according to the assess of Montreal Cog?nitive Assessment (MoCA). Univariate analysises were conducted in the potential risk factors of cognitive impairment in?cluding age, sex, smoking, alcohol, hypertension, diabetes, dyslipidemia, level of education, infarction in key parts, atrial fibrillation, serum uric acid, blood homocysteine between two groups. The statistically significant indicators in univariate analysises were used as independent variables and the scores of MoCA were used as the dependent variable to conduct multiple linear regression analysis. The assessment on the risk of cognitive impairment after cerebral infarction were con?ducted according to serum uric acid, sex, age and TOAST classification further. Results Serum uric acid was indepen?dent risk factors of cognitive disorder after acute cerebral infarction. The risk of cognitive disorder after acute cerebral in?farction was significantly increased in patients with high level of serum uric acid than with normal level and the relative risk was 1.35,95%CI(1.098,1.660). Especially for the young, male or patients with cerebral infarction in classification of small artery occlusion, the risk increased further, and the relative risk was 1.513, 95%CI(1.092, 2.096)1.412, 95%CI (1.125, 1.771)and 1.464, 95%CI(1.128, 1.900)respectively. Conclusion Exaltation of Serum uric acid was indepen?dent risk factor of cognitive disorder after acute cerebral infarction. The risk of cognitive disorder after acute cerebral in?farction was significantly increased in patients with high level of serum uric acid than with normal level, and especially for the young, male and patients with cerebral infarction in classification of small artery occlusion, the risk increased fur?ther.

BACKGROUND:Screw fixation of the fractured vertebral body can share the stress of implant, increase fixing strength, and help to maintain the stability of late fracture. However, whether it can assist reduction using fracture vertebral screw, but no relevant clinical reports were found at present. OBJECTIVE:To explore the effectiveness of self-designed screw-assisted reduction of fractured vertebrae. METHODS:161 cases of thoracolumbar fracture who had been hospitalized between June 2001 and June 2009 were enrol ed in this study, including 101 males and 60 females, at the age of 22-67 years, averagely 36 years. By Denis classification, 64 cases affected burst fractures and 97 flexion-compression fractures. Fracture levels involved T11 (9 cases), T12 (63 cases), L1 (74 cases) and L2 (15 cases). The self-designed method of reduction assisted with screw insertion was used. The efficacy of this reduction method was evaluated by operation time, intraoperative bleeding, fracture union time, height ratio of anterior borders of injured and normal vertebrae, sagittal Cobb’s angle, and reduction of fragments.
RESULTS AND CONCLUSION:The operation time ranged from 60 to 150 minutes, averaging 80 minutes. The intraoperative bleeding ranged from 67 to 750 mL, averaging 98 mL. The fol ow-up time ranged from 16 to 42 months in 161 patients. Fracture union time ranged from 10 to 18 weeks, averaging 12.6 weeks. The ratio of anterior heights and sagittal Cobb’s angle of fractured vertebrae were significantly improved from (54.39±9.60)%and (22.55±7.90)° respectively preoperati on to (82.80±6.63)%and (8.91°±5.85)° 12 months postoperation (P<0.05). The size of spinal canal was increased by (46.5±2.6)%postoperatively. CT scan revealed satisfactory fragment reduction and no deep infection appeared. These findings suggest that our self-designed screw-assisted reduction of the fractured vertebrae can improve the reduction quality in the treatment of thoracolumbar fractures.

Objective:To compare the effects between Begg and pre-adjusted appliance on dentofacial morphology in Angle class Ⅱ division 1 extraction cases treated by light archwire technique.Methods:28 cases with Angle class Ⅱ division 1 who needed maximum maxillary incisor retraction were divided into 2 groups (MBT pre-adjusted and Begg group) and treated by light archwire technique.4 first premolars were extracted in all patients.Lateral cephalometric films were analyzed before and after treatment.Results:The upper incisors were intruded (0.18 ± 0.32)mm and (0.77 ± 0.91) mm in pre-adjusted and Begg group respectively (P ＜ 0.05).The other differences of cephalometric analyses between 2 groups were not significant (P ＞ 0.05).Conclusion:The effects were almost same with pre-adjusted and Begg appliances in Angle class Ⅱ division 1 extraction cases treated by light archwire technique except for that the latter is better than the former in vertical control of maxillary anterior teeth.

Objective To investigate the effect of genistein on the proliferation,migration and invasion of prostate cancer cells and its molecular mechanism.Methods Prostate cancer LNCaP and CWR22RV1 cells were divided into the control group(conventional culture)and the experimental group(50μmol/L genistein treatment).The effect of genistein on the proliferation of prostate cancer cells were analyzed by MTT assay.The effect of genistein on the migration and invasion of prostate cancer cells were analyzed by cell scratch assay and Transwell assay.The protein levels of epithelial interstital transformation(EMT)intermediate markers E-Cadherin,N-Cadherin,Vimentin,and tumor stem cell markers CD44 and Oct-4 were detected by Western blot assay.Results MTT assay showed that genistein could inhibit the proliferation of prostate cancer cells.The scratch closure rates of LNCaP and CWR22RV1 cells were significantly reduced in the experimental group compared with those in the control group,and the number of cells passing through the Transwell membrane was significantly reduced(P＜0.05).Western blot assay showed that genistein could down-regulate the expression levels of N-Cadherin,Vimentin,CD44 and Oct4 in prostate cancer cells,and up-regulate the expression of E-Cadherin in epithelial cells(P＜0.01).Conclusion Genistein reduces the dryness of prostate cancer cells by inhibiting the EMT process,thus reducing the proliferation,migration and invasion of prostate cancer cells.
