OBJECTIVETo systematically evaluate the effectiveness of integrative medicine (IM) for preventing postoperative recurrence of primary hepatic carcinomas (PHC).
METHODSSuch databases as The Cochrane Library, PubMed, EMbase, China National Knowledge Infrastructure (CNKI), VIP Database, Wan-fang Database were retrieved to collect randomized controlled trials (RCTs) on preventing postoperative recurrence of PHC by IM. The retrieval period started from database establishment to June 2013. Literature screening, data extraction, and quality evaluation were performed by two reviewers strictly according to inclusion criteria. Meta-analysis was conducted using RevMan 5.2 Software.
RESULTSA total of 5 RCTs involving 367 patient cases were included. Results of Meta-analysis showed that the IM group was superior to the Western medicine (WM) group in the 1-, 2-, and 3-year recurrence rates (P < 0.05).
CONCLUSIONIn the prevention of postoperative recurrence of PHC, the effectiveness of IM was more significant, when compared with treatment of Western medicine.

Objective To investigate the efficacy of the clinical pathway in geriatric orthope-dics clinical teaching. Methods From March 2010 to December 2011, 80 clinical undergraduates, who practiced in the Department of Orthopedics in the Second Affiliated Hospital of Chongqing Medi-cal University, were equally randomized divided into two groups. One group was taught by the con-ventional methods and the other group was taught by the clinical pathway teaching. After the teaching, the theoretical exam and operational skill test were performed among students in both groups. SPSS 17.0 software was employed and the scores before and after the teaching and scores between two groups was analyzed by paired t-test(inspection level α=0.05). Results There was no significant difference in average scores between two groups before teaching(theoretical exam: P=0.81, operating skill test:P=0.65) while significant increases were observed in scores of theoretical exam and operational skill test after teaching (theoretical exam and operating skill test: P<0.05) and clinical pathway teaching group had higher scores than conventional teaching group (theoretical exam and operating skill test:P=0.02 and P=0.01). Conclusions Better effects can be achieved by clinical pathway approach re-garding geriatric orthopedics teaching.

Objective To study the brain functional activation under speech stimulation in presbycusis pa‐tients using blood oxygenation level dependent functional magnetic resonance imaging (BOLD - fMRI) .Methods Eighteen normal hearing young volunteers ,10 normal hearing elderly people and 10 presbycusis patients received fM ‐RI under auditory task .Experimental tasks included monosyllabic verbal stimulating at tone of 1 kHz and sound in‐tensity to 90 dB ± 3 dB(after ambient noise detector Smart Sensor AR844 measurement and calibration) randomly transmitted to left and right ear .Following block design ,each stimulus was repeated twice .The lateralization of brain activation analysis observed changes in hemispheric dominance cases (or ear advantage change) .We observed brain activation analysis and changes of hemispheric lateralization advantage (or ear advantages) .SPM5 software was used to deal with the original pictures in the off - line work station to get fictional maps ,volume and intensity of the acti‐vated brain regions of interest ,and calculate the laterality index (LI) .Results To young people ,regardless of left or right ear stimulation ,the contralateral (region of intrest ,ROI) activation volume and intensity significantly increased compared to ipsilateral ,appearing contralateral hemispheric dominance ,and laterality index were - 0 .58 (left ear stimulation) and 0 .37 (right ear stimulation) .Compared to young people ,elderly people with normal hearing and presbycusis contralateral hemisphere conduction advantage was significantly reduced under monaural stimulation ,and the laterality indexes were - 0 .24 ,0 .28 (the aged group) ,- 0 .18 ,0 .25 (presbycusis group) .Young people received the left and the right ear auditory task respectively ,and the ratio of the total volume of bilateral ROI activation was 1 :2 .06 ,appearing to the right ear advantage (left brain dominance) .While the aged and presbycusis group manifes‐ted as right ear advantage decreased (left ear advantage enhanced) ,whose the total volume ratio was 1 :1 .51 for the old normal subjects and 1 :1 .61 for the hearing impaired seniors .Conclusion Auditory verbal tasks activated brain regions in the superior temporal gyrus and middle temporal gyrus were most obvious .Aging may cause these brain regions to be activated weaker ,appearing to the trend of contralateral hemisphere .The aging and deafness lead to the cortical reorganization .This may be one of the reasons for the declined speech recognition .

Objective To understand the situation of off-label use of sildenafil, so as to provide reference for developing off-label drug use policy. Methods A stratified random sampling method was used to collect prescription data of sildenafil in Guangdong Women and Children Hospital in 2015. The off-label drug use situation was analyzed according to drug labels. The situations of drug use in all departments were summarized, and off-label drug use occurrences were analyzed.Results A total of 1044 prescriptions with sildenafil were collected and analyzed to discover the occurrence of off-label use was up to 69. 54%. The top 3 departments of off-label use of sildenafil were assisted reproductive center, heart center and neonatal intensive care unit (NICU). The top 3 types of off-label use were non-indication(50. 35%), over drug population(31. 76%) and over drug administration(17. 89%). The top 3 diseases for non-indications were infertility, pulmonary hypertension and congenital heart disease. Conclusion Sildenafil off-label use was common in Guangdong Women and Children Hospital in 2015, especially in assisted reproductive center, heart center, and NICU. The result suggests that more clinical studies about sildenafil on cardiovascular system are expected to provide more evidence for drug use, so as to ensure the safety of drug use in special populations and avoid potential medical risk.
