Objective To investigate the relation between the expression of toll receptor-4 (TLR-4) and the increase of blood brain barrier (BBB) permeability in the rats with acute pancreatitis.Methods Male Sprague-Dawley rats were randomly divided into 8 groups:control group;acute edematous pancreatitis (AEP) 2 h,6 h groups;acute necrotizing pancreatitis (ANP) 2 h,6 h,12 h,24 h,48 h groups with 8 rats in each group.The BBB permeability,pathological score of pancreas,TLR-4 expression were determined and the relationships between them were analyzed.Results The BBB permeability in control group;acute edematous pancreatitis (AEP) 2 h,6 h groups;ANP 2 h,6 h,12 h,24 h,48 h groups were 1.55±0.29,1.64±0.17,1.69±0.24,1.89±0.12,2.66±0.32,2.91±0.29,2.89±0.69 and 1.84±0.07,respectively;the pathological scores of pancreas were 0,2.38±0.92,3.13±0.64,8.50±1.07,9.75±0.71,10.25±1.28,11.13±1.25 and 10.13±1.13,respectively;there was no significant difference between AEP groups and control group,while there was significant difference between AEP groups and ANP groups (P<0.05 orP <0.01).BBB permeability was correlated with pancreatic injury ( r = 0.626,P <0.01).There was no TLR-4 mRNA and protein expression in the control and AEP group,while they were significantly expressed in ANP groups,and the expression were positively related with BBB permeability ( r =0.208,P = 0.027 ).Conclusions BBB permeability was present in the course of ANP.Activation of TLR-4 signal pathway may be involved in the BBB permeability increase caused by ANP.

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

Objective To study the effect of dexmedetomidine (DEX) on postoperative cognitive function and preoperative inflammation in the elderly patients undergoing general anesthesia. Methods 70 elderly patients undergoing general anesthesia operation were chosen and divided into observation group and control group randomly. DEX and physiological saline were applied in observation group on the basis of routine general anesthesia. The cognitive function of patients in both groups were tested by mini-mental state examination (MMSE) and the incidence rate of cognitive dysfunction (POCD) were measured at 1 day before surgery, 1 day, 3 days, 5 days, and 7 days after surgery. The level of interleukin-6 (IL-6) and tumor necrosis factor-α(TNF-α) were tested before anesthesia, during skin incision, rightly after operation and 1h after operation. Results MMSE scores were significantly higher and the incident rates of POCD were lower in observation group than those in control group at 1 day and 3 days after surgery (P<0.05). The levels of IL-6 and TNF-αincreased obviously during skin incision and postoperative period, and they were significantly lower in observation group (P<0.05). The levels of IL-6 and TNF-αdecreased to the levels before anesthesia in observation group, and were still much higher in control group than that of preanesthesia (P < 0.05). Conclusions DEX infusion intraoperatively may effectively decrease the incidence of early POCD, whose mechanism could be reducing inflammation response.

Objective To compare the difference in bioavailability of ligusticum wallichii microemulsion and decoction by detecting the concentration of Ferulic acid in rabbit plasma. Methods RP-HPLC was used to detect the concentration of Ferulic acid in rabbits plasma at different times, and software 3p87 was used to analyze the pharmacokinetics parameter. Results The pharmacokinetics parameters of ligusticum wallichii microemulsion and decoction were as follows: AUC0-9=2 123.6 μg/(ml?min), Cmax=5.086 μg/ml, Tpeak=56.26 min for microemulsion;Decoction:AUC0-9=878.35 μg/(ml?min), Cmax=2.427μg/ml, Tpeak=128.86 min for decoction, F(%)=241.77. Conclusion Microemulsion of ligusticum wallichii has a higher biological availability and shorter peak time than decoction.

Objective To observe the effects of recombinant human bone morphogenetic protein-2 (rhBMP-2) on patients with type A thoracolumbar fractures treated by pedicle screw fixation via dorsal-approach and vertebral body bone graft.Methods A retrospective case-control study was conducted to analyze the clinical data of 64 patients with type A thoracolumbar fractures treated from June 2012 to July 2015.The patients were divided into control group (32 cases) and research group (32 cases) according to the random number table.There were 22 males and 10 females aged (48.2 ± 11.2)years old in control group.The injury was located at T11 in 2 cases,T12 in 4,L1 in 9,L2 in 7,L3 in 7 and L4 in 3 in control group.There were 24 males and 8 females aged (50.7 ± 11.4) years old in research group.The injury was located at T11in 2 cases,T12in 4,L1in 8,L2 in 8,L3 in 7 and L4 in 3.The control group was treated with posterior pedicle screw reduction,internal fixation and allograft cancellous bone grafting through pedicle of vertebral arch.The research group was treated with rhBMP-2 (mixed with cancellous bone implants) on the basis of the control group.The time of operation,the amount of bleeding during operation,the volume of postoperative bleeding,the amount of postoperative drainage,the recovery of the injured vertebra,the Lane-Sandhu score,the time of fracture healing,and the postoperative complications were compared.Results There was no difference between two groups on operation time,amount of bleeding during operation or amount of postoperative drainage (P > 0.05).No difference existed in two groups about Cobb angle and injured vertebral leading edge height at one week after operation (P > 0.05).At the time of last follow-up (12 months),in research group,Cobb angle was lower while injured vertebral leading edge height was much higher than that of control group (P < 0.05),both of which were better than before (P < 0.05).At 12 months after surgery,the lost Cobb angle of [(2.0 ± 0.7) °] and lost height of injured vertebral leading edge [(3.2 ± 1.0) %] were smaller than those in control group [(5.6 ± 1.7) ° and (6.8 ± 2.4) % respectively] (P < 0.05).The Lane-Sandhu score and healing time of fracture in research group were (8.9 ± 0.8) points and (6.9 ± 0.9) months,which were better than that (6.8 ±0.8)points and (8.4 ± 1.6)months in control group respectively (P<0.05).The complication rate of research group was lower than that of control group,with no significant difference (P > 0.05).Conclusion Compared with simple vertebral bone graft,posterior thoracolumbar vertebrae pedicle screw fixation with vertebral bone graft and hBMP-2 treatment for type A thoracolumbar fractures can restore vertebral stability,shorten the time of fracture healing and reduce the incidence of complications.

Objective To investigate the behavioral problems and self-concept of children with oppositional defiant disorder (ODD) and the correlation between them. Methods The subjects came from a sample survey of primary and middle school students' mental status in 6 regions in Hunan province. Achenbach child behavior checklist (CBCL) was filled out by parents. The Children's self-concept scale (CSCS) was completed by children themselves. Results There were significant differences between the scores of ODD group and the normal control among all CBCL subscales except the activities scale, and the scores for the CSCS scales were all lower in patients with ODD than the control group except for the physical appearance and attributes (P<0.01). In addition, according to correlation analysis, the CBCL scores yielded small but significant correlations with the CSCS scores for children with ODD(P<0.05). Conclusion Children with ODD have generally behavioral problems, poor social competence, and lower self-concept, whose behaviors were correlated with their self-concept.
