Objective:To analyze the curative effects of laparoscopic radical prostatectomy for the prostate cancer and the its effect on the level serum hormones levels.Methods:86 patients with prostate cancer were selected and divided into the control group and the observation group with 43 cases in each group according to the draw method.The control group was treated by open radical prostatectomy,while the observation group was treated by laparoscopic radical prostatectomy.The operation indicators,serum follicle stimulating hormone (FSH),luteinizing hormone (LH),dihydrotestosterone (DHT),free testosterone (FT),total testosterone (T),prostate specific antigen (T-PSA,F-PSA) levels,CD3+,CD4+,CD8+,CD4+/CD8+ before and after the surgery as well as the occurrence of postoperative complications were compared between two groups.Results:The operation time of observation group was significantly longer than that of the control group,and the blood loss,bowel function recovery time,hospital stay,pain scores of observation group was significantly lower or shorter than those of the control group (P＜0.05).No significant difference was found in the serum FSH,LH,DHT,FT,T,T-PSA,F-PSA levels before and after the surgery between two group(P＞0.05).The CD3+,CD4+,CD4+/CD8+ of observation group was significantly higher than those of the control group (P＜0.05),the CD8+ of observation group was lower than that of the control group(P＜ 0.05).The incidence rate of postoperative complication in the observation group was significantly lower than that of the control group (P＜0.05).Conclusion:Laparoscopic radical prostatectomy could play a similar effect with the open surgery on the tumor control,it could improve the level of serum testosterone,immune function with high safety.

Objective To compare the therapeutic differences between stent-thrombectomy combined with urokinase thrombolysis and simple arterial urokinase thrombolysis in treating patients with acute cerebral infarction.Methods Arterial urokinase thrombolysis was carried out in 28 selected patients with acute cerebral infarction,admitted to our hospital in 2011 (urokinase group),while Solitaire AB stent-thrombectomy combined with arterial urokinase thrombolysis was carried out in 29 patients with acute cerebral infarction,admitted to our hospital in 2012 (combination group).Postoperative indices,including National Institutes of Health Stroke Scale (NIHSS),recanalization rate and intracranial hemorrhage incidence,were analyzed between the two groups.Results Recanaliztion rate of combination group was detailed as:middle cerebral artery in 20 patients,internal carotid artery in 3 patients,and vertebral-basilar artery in 4 patients,with a total recanalization rate of 93.1％.No postoperative hemorrhage was confirmed; two patients diagnosed as having internal carotid artery occlusion died.Recanaliztion rate of urokinase group was detailed as:middle cerebral artery in 15 patients,internal carotid artery in 3 patients,and vertebral-basilar artery in 0 patients,with a total recanalization rate of 64.2％; postopertive intracranial hemorrhage was noted in 5 patients and death in 8.For combination group,postoperative fourteen-day NIHSS scores decreased by 11.40±4.57 as compared with preoperative NIHSS scores; for urokinase group,postoperative fourteen-day NIHSS scores decreased by 11.40±4.57 as compared with preoperative NIHSS scores; significant differece was noted between the two groups (P＜0.05).Postoperative satisfactory rehabilitation (modified Rankin scale scores＜2) in combination group and urokinase group appeared in 20 and 17 patients,respectively,after 3 months of follow up.Conclusion The efficacy of stent-thrombectomy combined with arterial urokinase thrombolysis is superior to that of simple arterial urokinase thrombolysis in patients with acute cerebral infarction.

Objective: To explore the related factors for primary hepatic carcinoma (PHC) caused by chronic hepatitis B (CHB) and hepatitis C (CHC). Methods: According to the principle of cross-sectional study, a cluster random sample method was used, a total of 366 chronic hepatitis patients in hospitals were recruited from three provincial tertiary hospitals in Shanxi, Henan and Jilin between July 2016 and October 2016, respectively. Using a self-designed unified questionnaire, face-to-face interviews was conducted on subjects, including sex, age, alcohol consumption, coffee consumption, green tea consumption, fish consumption, smoking, HBV/HCV diagnosis and treatment, diabetes mellitus, family history of PHC (whether PHC in first-degree relatives), etc. Multivariate unconditional logistic regression were performed to identify the related factors for PHC with CHB and CHC. According to the clinical diagnosis the patients were divided into a chronic hepatitis group (not developing to PHC) and a PHC group. Results: Among 366 cases patients, 287 (78.4%) cases were male, 79 cases were female (21.6%), average age was (52.7±9.3) years. 202 cases were chronic hepatitis group, 164 cases were PHC group. Multivariate unconditional logistics regression analysis indicated that alcohol consumption (odds ratio (OR)=2.11, 95%CI: 1.18-3.75), family history of PHC (OR=5.12, 95%CI: 2.60-10.08) were positively correlated with the development of PHC in chronic b, green tea consumption (OR=0.45, 95%CI: 0.23-0.88), antiviral treatment (OR=0.19, 95%CI: 0.11-0.32) were negatively correlated. Alcohol consumption (OR=3.98, 95%CI: 1.14-13.85) was positively correlated with the development of PHC in chronic c, antiviral treatment (OR=0.14, 95%CI: 0.04-0.50) was negatively correlated. Conclusion Alcohol consumption, family history of PHC, green tea consumption and antiviral treatment were the related factors for the development of PHC in chronic hepatitis b. Alcohol consumption and antiviral treatment were the related factors for the development of PHC in chronic hepatitis c.

OBJECTIVETo perform a prospective,multicenter,open,randomized study to determine a treatment regimen for treatment-naive patients with refractory chronic hepatitis C (RHC) using the predictive value (PV) of early virological response (EVR).

METHODSA total of 438 patients from 18 hospitals were recruited between December 2008 and December 2010 and administered peg-interferon/ribavirin treatment for 12 weeks. Patients who achieved complete EVR (cEVR) were assigned to group A for a 48-week course of treatment, while patients without cEVR were randomly allocated to either group B 1 for a 72-week course of treatment or to group B2 for a 96-week course of treatment. Serum hepatitis C virus RNA levels at baseline,treatment weeks 4, 12 and 24, end of treatment, and post-treatment week 24 were measured and used to evaluate the efficiency of therapy.

RESULTSThe overall sustained virological response (SVR) rate was 85.1%. In all, 91.0% of patients achieved cEVR and were assigned to group A, which had an SVR rate of 90.8%. There was no statistically significant difference in the SVR rates of groups B1 and B2 (29.4% vs. 25.0%, P more than 0.05). The positive PV of rapid virological response (RVR), cEVR and delayed virological response (DVR) for SVR was 93.4%, 90.8% and 77.8% respectively, and the negative PV of RVR, EVR and DVR for SVR was 28.0%, 93.3% and 100% respectively. Overall, 66.9% of the patients experienced adverse events (AEs), but only 1.9% of patients experienced sevcre AEs.

CONCLUSIONThe majority of Chinese RHC treatmentna(i)ve patients (91.0%) can achieve cEVR and a high SVR rate with a low rate of severe AEs using the cEVR guided personal treatment regimen.

Objective: To establish and verify the validity of a finite element(FE) model of fragment injury in swine mandibular composite tissue. Methods: Swine facial composite tissue digital information was obtained by 3D CT,the 3D model and the cylinder fragment with the diameter and height of 5. 5 mm were reconstructed and designed in mimics15. 0. The right mandibular angle region was impacted by the fragment with velocities in finite element analysis software. A two stage light gas gun was used to launch the same shape 30CrMnSi alloy fragment with the speed of 831,1 120 and 1 536 m/s respectively to impact swine mandibular angle area. The actual damage area and acceleration at jaw were measured and compared with the digital simulation results. Results: Compared with the data of digital simulation the fragment with the speed of 831,1 120 and 1 536 m/s resulted in the larger mandibular damage area of entry in the in vivo experiment by 13. 4％,23. 6％ and 22. 3％; that of exit by 18. 7％,23. 0％ and 26. 5％; the smallar accelaration peak by 16. 7％,15. 3％ and 14. 6％,respectively. Conclusion: A digital model of the swine mandible composite tissue fragment injury model is established. The simulation results of the FE model are consistent similar to those of the in vivo test data.

Objective: To compare the effects of surgical and conservative therapy in the treatment of orbital blow-out fracture. Methods: 90 cases of obital blow-out fracture were treated by surgical(n = 40) and conservative(n = 50) trerapy respectively, the patients were fllowed up for 12 months. The treatment outcome was retrospectively analysed. Results: Of the 40 patients managed surgically 39 were with complete follow up data, 19 had diplopia in peripheral gaze before surgery, 13 (33％) had at 3-month and 12 (31％) had at 6-month follow-up. 31 had enophthalmus before surgery and 3(8％) had at 3-month and 6-month follow-up. Of the 50 patients managed conservatively 26 were with complete follow-up data, 11 had diplopia in peripheral gaze initially, 9(35％) had at 3-month and 8(31％) had at 6-month follow-up. 15 had enophthalmus initially and 13(50％) had at 3-month and 6-month followup. Conclusion: Surgical therapy is more effective for the treatment of enophthalmus. The effects tend to be stable 3 months after treatment, the ratio of diplopia in peripheral gaze after treatment by the 2 treatments is similar(about 30％ of the total cases).

ObjectiveTo explore the relationship between schizotypal personality traits and creativity in college students and the mediating role of cognitive flexibility. MethodsSchizotypal Personality Questionnaire （SPQ）， Cognitive Flexibility Inventory （CFI） and Williams Creative Aptitude Test （WCAT） were used to assess 471 college students. Thereafter， Spearman correlation analysis was used to explore the relationship among the variables and the Bootstrap methodology was used to estimate the mediating role of cognitive flexibility. ResultsThe total SPQ， positive and disorganized schizotypal traits scores， and CFI score were all positively correlated with WCAT score （r=0.241~0.313， P<0.01）. The total SPQ， positive and disorganized schizotypal traits scores were also positively correlated with CFI score （r=0.111~0.128， P<0.05）. Cognitive flexibility mediated the relationship between positive schizotypal traits and creativity ［indirect effect=0.052 （95% CI： 0.016~0.112， P<0.01）， accounting for 11.93% of the total effect］. Cognitive flexibility mediated the relationship between disorganized schizotypal traits and creativity ［indirect effect=0.075 （95% CI： 0.020~0.161， P<0.01）， accounting for 11.50% of the total effect］. ConclusionSchizotypal personality has a direct impact on the creativity of medical students and also cause an indirect impact on their creativity through the mediating role of cognitive flexibility.
