AIM To review evidence on the short-term clinical outcomes of laparoscopic(Lrr) vs open rectal resection(Orr) for rectal *** A systematic literature search was performed using Cochrane Central register, MEdLINE, EMBASE, Scopus, Open grey and Clinical *** register for randomized clinical trials(rCTs) comparing Lrr vs Orr for rectal cancer and reporting short-term clinical outcomes. Articles published in English from January 1, 1995 to June, 30 2016 that met the selection criteria were retrieved and reviewed. The preferr.d.reporting Items for Systematic reviews and Meta-Analysis(prISMA) statements checklist for reporting a systematic review was followed. random-effect models were used to estimate mean differences and risk ratios. The robustness and heterogeneity of the results were explor.d.by performing sensitivity analyses. The pooledeffect was consider.d.significant when p rall, 14 rCTs were included. No differences were found in postoperative mortality(p = 0.19) and morbidity(p = 0.75) rates. The mean operative time was 36.67 min longer(95%CI: 27.22-46.11, p d blood loss was 88.80 ml lower(95%CI:-117.25 to-60.34, p d the mean incision length was 11.17 cm smaller(95%CI:-13.88 to-8.47, p r Lrr than Orr. These results were confirmed by sensitivity analyses that focused on the four major rCTs. The mean length of hospital stay was 1.71 d shorter(95%CI:-2.84 to-0.58, p r Lrr than Orr. Similarly, bowel recovery(i.e., day of the first bowel movement) was 0.68 d shorter(95%CI:-1.00 to-0.36, p r Lrr. The sensitivity analysis did not confirm a significant difference between Lrr and Orr for these latter two parameters. The overall quality of the evidence was rated as high. CONCLUSION Lrr is associated with lesser blood loss, smaller incision length, and longer operative times compar.d.to Orr. No differences are observed for postoperative morbidity and mortality.

The detailed electrical conductivity measure- ment (ECM), trace chemical compositions and microparti- cles concentration analysis are performed for BH8 ice core from the depth of 126.0m to 130.0m at Vostok Station. At depth 128.7m, a volcanic signal 4726 a B.p. is detected. The volcanic sulphate flux is 95.8 kg·km?2, sulphate peak concen- tration 1352.8 ng·g?1, duration time about 10.1 years, com- parable with some well-known volcanic events. The results indicate that it seems to be a relatively large scale, long last- ing volcanic signal with farther volcanic origin.
