Objective To assess the predictive value of serum uric acid levels to the incident nonalcoholic fatty liver disease(NAFLD)in a cohort of healthy population. Methods A prospective cohort study of NAFLD incidence was conducted in Xinjiang province, from 2012 to 2014. A cohort study was performed on 2 207 subjects with no evidence of fatty liver disease by liver ultrasound and with no major risk factors for liver disease at baseline. All participants were interviewed to carry out the epidemiological questionnaire survey, physical examination, abdominal ultrasonography, as well as blood biochemistry measurements. The hazard ratios of NAFLD were compared among groups with different uric acid levels. All subjects were classified according to serum uric acid (within normal range grouped by quartile: Q1-Q4 group; above the normal range: Q5 group). Results NAFLD was newly diagnosed in 13.72% subjects within the 3-year period. The incidence of NAFLD was increased with elevated serum uric acid quartiles(P<0.01). In multivariate logistic regression, after adjustment for gender, age, race, metabolic syndrome and its components, OR for incident fatty liver in Q2 to Q5 of serum uric acid concentration as compared to Q1 were 2.509, 3.172, 3.392, and 4.041 respectively. Conclusion Elevated serum uric acid concentrations may predict NAFLD in the subjects for a regular health checkup.

ObjectiveTo analyze the correlation between serum 25-hydroxyvitamin D level and nonalcoholic fatty liver disease (NAFLD), and to provide a clinical basis for the prevention and treatment of NAFLD. MethodsFrom March to October, 2014, 200 Uyghur patients and 200 Han patients with NAFLD in our hospital were enrolled into NAFLD group, while an equal number of healthy Uyghurs and Hans were used as controls. For all subjects, questionnaire survey, physical examination, abdominal ultrasound examination, and blood biochemical examination were performed, and serum 25-hydroxyvitamin D level was determined using enzyme-linked immunosorbent assay. The relationship between 25-hydroxyvitamin D and NAFLD was analyzed by Spearman correlation analysis and multivariate logistic regression analysis. ResultsSerum 25-hydroxyvitamin D levels in the NAFLD group were significantly lower than those in the control group for both Uyghurs and Hans (P＜0.05), and serum 25-hydroxyvitamin D level was negatively correlated with NAFLD (rHan=-0.212, rUyghur=-0.220, P＜0.01). The results of multivariate logistic regression analysis showed that the rising serum 25-hydroxyvitamin D level was a protective factor for NAFLD (ORHan=0.894, PHan=0.015; ORUyghur=0.897, PUyghur=0.025). ConclusionSerum 25-hydroxyvitamin D level is closely associated with NAFLD in Uyghurs and Hans.

Objective To verify the efficiency of a new laparoscopic urethrovesical anastomosis training model by comparing it with the chicken skin model. Methods Chicken posterior trunks and porcine colons were used to construct the training model. The posterior trunk of a chicken was used to simulate a human pelvis, and a 3-mm cloacal stump was used to simulate a human urethral stump. A 15-cm segment of porcine colon with a 1-cm orifice was used to simulate a human bladder or neobladder. An imitation urethrovesical anastomosis was performed with laparoscopic instruments in a laparoscopic training box. Forty trainees with no laparoscopic experience were randomized into 2 groups.The trainees in group A (n=20) practiced using this new model for 8 h, while those in group B (n=20) practiced using the chicken skin model for 8 h. The trainees' skills were assessed using the porcine model before and after training. Results Compared with the chicken skin model, this new training model more accurately resembled the structure and characteristic of human pelvis, urethral stump, and bladder (neobladder). After the training sessions, both groups improved in anastomosis time [GroupA: (64±11)min vs. (123±20)min, P＜0.05; Group B: (77±12)min vs. (121±17)min, P＜0.05] and quality (Group A: 8.8± 1.0 vs. 3.8 ± 1.2, P＜0. 05 ; Group B: 7.7 ± 0.9 vs.3. 7± 1.1, P＜0. 05). Compared with trainees in group B, trainees in group A required less time and achieved a higher quality score (P＜0.05). Conclusions This new training model can help urologic surgeons to reduce learning curve of this technique and improve their suturing skills. It is an effective,convenient training model for laparoscopic urethrovesical anastomosis.

Objective To obtain shRNA sequences that can stably block the expression of Nuclear Factor kappa- B (p65) in the prostate cancer cell line LNCaP and construct the lentivirus vector.And validate the gene function of p65 in the cell line. Methods According to p65 genetic information, we design siRNA1, siRNA2, siRNA3 those three siRNA sequences targeting the ods area of p65 gene and then form the corresponding four pairs of complementary single strand DNA of shRNA, including the sense strand and the antisense strand. The synthetic shRNA sequence was inserted into the empty pSIH1-H1-copGFP shRNA Vector, and after transfecting the prostate cancer cells , the inhibitory effect of p65 mRNA by different sequences was detected through real-time PCR, and the inhibitory effect of p65 protein expression was detected by Western-blotting. Thus we can obtain highly effective shRNA sequences in the inhibition of p65 in prostate cancer cells. MTT, flow cytometry, transwell were chosen to test the cell growth, migration and invasive power in vitro to compare the difference of the experimental group, control group and negative group. Results The third shRNA sequence had the best inhibitory effect and the inhibitory effect of p65 mRNA in prostate cancer cell line was 59 % and the protein was 81%. It's position locates in p65 (NM_021975 ) 1096-1113 and it's stemloop sequence is 5'-GATCCGCCCTATCCCTTTACGTCATTCAAGAGATGACGTAAAGGGATAGGGCTTTTTG-3'. After transfecting, the prostate cancer cell line had the low expression of p65 stably. Through MTT, we got the growth curve, which showed that the growth ability of experimental group was significantly decreased compared with the control group and the Logarithmic growth didn't appear in the first 96 hours. Flow cytometry test displayed that the percentage of G0-G1-phase cells in experimental group was 61.49%, and the control group was 44.89%, idle group was 41.52%, which was increasing oberviously. The S-phase cells in the experimental group was 28.58%, compared with the 47.36% and 46. 10% diminished. The results of transwell showed that the experimental group had 16. 5000±6. 62076 cells and the other two groups had 45. 6333 13. 54159 and 36. 8333±5. 68412 cells, which showed the invasive power of experimental group was significantly declined(P＜0.05).Conclusions It's successful to obtain shRNA sequences that can stably block the expression of p65 in the prostate cancer cell line LNCaP and construct the lentivirus vector. p65 can positively regulates the biological behavior of prostate cancer LNCaP cell line in the cell growth, migration and invasive power.

Objective To investigate the predictive value of acute physiology and chronic health score ( APCHE Ⅱ) scoring system on the patients with acute coronary syndrome ( ACS) , and to demonstrate whether the predictive value combined with TIMI risk score impact on prognosis. Methods We calculated APACHEⅡ, TIMI risk score and total score of these two for 198 patients with acute coronary syndrome ( ACS) in CCU, and compared the discriminative power of the three scores by the area under the receiver operating characteristic curve ( AUROCC ) . Results The APACHEⅡscores of survival group ( 9. 42 ± 3. 38 ) and death group (14. 77 ± 3. 27) were statistically significant (t= -8. 018,P<0. 01). The survival groups of TIMI risk score was (3.48±0.96), while the score of death group (5.57 ±0.68), (t = -11.383,P<0.01). For ST segment elevation myocardial infarction group, the score of APACHEⅡwas ( 10. 33 ± 3. 86 ) and predicted mortality 11. 61% (13/112) and actually mortality 18. 75% (21/112) (χ2 =15. 998,P <0. 01); in non-ST segment elevation myocardial infarction group, the score of APACHEⅡwas ( 10. 10 ± 4. 14 ) and predicted mortality 11. 63% (10/86) and actually mortality 10. 47% (9/86) (χ2 =79. 330,P>0. 05);for the total ACS, the score of APACHEⅡwas (10. 23 ± 3. 86) and predicted mortality 11. 62% (23/198) and actually mortality 15. 15%(30/198) (χ2 =29. 892,P<0. 01). The ROC curve area of 3 score methods had been compared and found out TIMI had the biggest ROC curve area and the best predicted livability and mortality. Conclusions APACHEⅡscore can not predict mortality satisfactorily in patients with ACS well, and the method of APACHEⅡcombined with TIMI risk score is not better than TIMI risk score showed in the study. The TIMI risk score is a quick, convenient and effective method to evaluate patients with ACS.

Objective To investigate the status quo of wander behavior among inpatients with senile dementia and discuss relevant risk factors.Methods Totally 84 inpatients with senile dementia from the Department of Geriatrics of Shanghai Mental Health Center were selected, evaluated with Revised-Algase Wandering Scale (RAWS), Mini Mental State Examination (MMSE) and Narcissistic Personality Inventory (NPI), and divided into a wandering group (69 patients) and a non-wandering group (15 patients). The risk factors related to wander behavior were analyzed.Results The incidence of wander behavior among the inpatients with senile dementia was 82.1%, with spatial disorientation as the main form in RAWS factor analysis; The MMSE score of the patients in the wandering group was (2.58±5.65), lower than that of the patients in the non-wandering group, and their NPI score was (17.88±7.93), higher than that of the patients in the non-wandering group (t=2.89, 2.21;P<0.05). According to the Logistic Stepwise Multiple Regression, wander was closely related to severity of dementia, mental and behavior disorder and NPI apatheia.Conclusions Wander behavior is widely found among patients with senile dementia and brings great difficulty to their caregivers. Therefore, studies on their causes play a practical part in improving the treatment, nursing and family care for patients with senile dementia and preventing them from getting lost, felling down and being injured.
