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.

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.

This study was aimed to screen main active site to reduce blood lipid from Xin-Mai (XM) capsule and establish HPLC fingerprint of the site, in order to study the correlativity between active site and relevant fractions of its herbs. Solvent extraction was used to separate XM capsule into different polar fractions. Intraperitoneal injection of 75% egg-yolk emulsion was used to establish mice hyperlipidemia models. And the active site was screened. Chromatographic fingerprints of the site and relevant fractions of its herbs were configured by HPLC analysis. The
retention time of peaks was utilized as index to evaluate the correlativity. The results showed that lipid-lowering effect of ethyl acetate extract and garlic essential oil was significant (P<0.01). Fingerprint of the active site in XM capsule was established with 28 fingerprint peaks and the assignment results of 27 peaks were indicated. It was concluded that the active sites to reduce blood lipid of XM capsule were ethyl acetate extract and garlic essential oil. The established fingerprint method can effectively determine the correlativity between the active site and its relevant fractions, which contributed to pharmacodynamic material foundation and quality standard.

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.
