[Objective] To confirm the effects of Neiguan massaged to prevent ache nausea and vomit after laparoscopic cholecystectomy(LC).[Methods] 400 patients were randomly divide into 2 groups;the group 1 were treated by Neiguan massage during the LC,the group 2 nothing during the operation.[Results]Group 1 suffered the same ache in the 1st hour as group 2,but less in the last 24h,and less nausea and vomit too.[Conclusions ]Neiguan massage could obviously prevent ache nausea and vomit after LC.

BACKGROUNDWhat benefits and toxicities patients acquire from the use of bevacizumab combined with firstline chemotherapy remains controversial. This study was performed to evaluate the efficacy and safety of first-line chemotherapy plus bevacizumab in patients with metastatic colorectal cancer (mCRC).

METHODSSeveral databases, including PubMed, Embase, and Cochrane Library, were searched up to April 30, 2013. Eligible studies were only randomized, controlled trials (RCTs) with a direct comparison between mCRC patients treated with and without bevacizumab. Overall risk ratio (RR), hazard ratio (HR), odds ratio (OR), and 95% confidence intervals (CI) were calculated employing fixed or random-effects models depending on the heterogeneity of the included trials.

RESULTSSix RCTs, including 1582 patients in chemotherapy plus bevacizumab group and 1484 patients in chemotherapyalone group, were included. Overall, the addition of bevacizumab to first-line chemotherapy increased overall response rate (ORR) by 4.5%, prolonged both progression-free survival (PFS) and overall survival (OS), and increased the rate of total Grades 3 or 4 adverse events (G3/4AEs) by 6.9%. Significant differences were found in ORR (RR = 1.22 (95% CI 1.01-1.46), P = 0.03), PFS (HR = 0.60 (95% CI 0.47-0.77), P < 0.0001), OS (HR = 0.83 (95% CI 0.70-0.97), P = 0.02), and any G3/4AEs (OR = 1.56 (95% CI 1.29-1.89), P < 0.00001).

CONCLUSIONBevacizumab is a valuable addition to the current first-line chemotherapy regimens used in patients with mCRC, because of conferring a significant improvement in ORR, PFS, and OS, even though it increased adverse events.
