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 explore the influence of group psychotherapy on the alleviation of psychiatric nurses' compassion fatigue.Methods A total of 190 psychiatric nurses were investigated by compassion fatigue scale.Forty psychiatric nurses were selected to accept group psychotherapy for 10 times.The scores of compassion fatigue scale were compared before and after group psychotherapy and the influencing factors of therapeutic effect were analyzed.Results Thirty-eight psychiatric nurses had accomplished the intervention and follow-up.Compared with before group psychotherapy,the total scores of compassion fatigue scale and the scores of mental tension,passive behavior,doubtful ability and loss of morale among 6 dimensions after group psychotherapy were improved:(83.28±7.01) scores vs.(102.60±7.24) scores,(2.66±0.42) scores vs.(3.11±0.49) scores,(2.02±0.36) scores vs.(2.55±0.41) scores,(1.99±0.33)scores vs.(2.65±0.38) scores,(1.69±0.34) scores vs.(2.76±0.44) scores,and there were significant differences,P＜0.05.Regression analysis found that the work life,education level were correlated with the deduction rate of the total scores of compassion fatigue scale,t=2.858,3.099,P＜0.01.Conclusion Group psychotherapy can help psychiatric nurses to alleviate their compassion fatigue.

Surface electromyogram (sEMG) may have low signal to noise ratios. An adaptive wavelet thresholding technique was developed in this study to remove noise contamination from sEMG signals. Compared with convention- al wavelet thresholding methods, the adaptive approach can adjust thresholds based on different signal to noise ratios of the processed signal, thus effectively removing noise contamination and reducing distortion of the EMG signal. The advantage of the developed adaptive thresholding method was demonstrated using simulated and experimental sEMG recordings.

At 2:28 p.m. local time on 12 May, 2008, the Wenchuan earthquake struck with a magnitude of 8.0. After the earthquake, 1364 injured persons, including 732 women and 632 men, were admitted to Deyang People's Hospital. The ages of the injured persons ranged from 0.2 years to 102 years (mean, 42.5 years). Of all injured persons, 4.65% aged under 7 years, 13.84% between 7 and 18 years, 39.57% between 19 and 45 years, 24.48% between 46 and 65 years, and 17.46% above 65 years. A total of 1713 injuries were found in all the injured persons, and the predominant injuries were found in limbs, body surface, head and chest. The incidence of the multiple injuries was 23.64%. Eighteen persons with abdominal injuries received operation. Prompt, accurate and systematic evaluation of the injury is necessary in raising the rescue efficiency. Treating the injured persons according to a classification optimizes the usage of the limited medical resources. Early definitive operation is crucial in rescuing the lives of the injured persons, and the treatment should be applied within 24 hours after the earthquake, then the emphasis of the rescue work should shift to helping orthopedic surgeons with operation and debridement.
