OBJECTIVE:To improve the quality of ADR reports. METHODS:By using intensive hospital monitoring mode, ADR reports before and after the application of the system would be collected and factors as report quantity,type,time and quality of reports were analyzed statistically. RESULTS:It provided rapid reporting function after the implementotion of the system. Total quantity of reported ADR cases increased from 589 to 748,and the proportion of all the serious ADR reports increased from 62.8%to 11.76%. The score of repert quality increased from 93.64 to 98.36,the proportion of time-out reports increased from 94.05% to 97.33%,with statistical significance (P<0.05). CONCLUSIONS:Rapid reporting system of ADR in the hospital is beneficial to improve the efficiency and guarantee the quality of the reports. It also can expand the coverage of the monitoring network,and can lay the foundation for drug safety scientific evaluation and monitoring.

OBJECTIVETo evaluate the clinical application of carbon nanoparticles labeled lymph node staining in curative laparoscopic resection for colorectal carcinoma.

METHODSSixty-five patients undergoing curative laparoscopic resection for colorectal carcinoma in the Sun Yat-sen Memorial Hospital between September 2011 and June 2013 were prospectively enrolled and randomly divided into label group (with carbon nanoparticles, n=34) and control group (without carbon nanoparticles, n=31). Association between labeled lymph nodes and metastasis was analyzed. The total number of retrieved lymph nodes and lymph nodes metastatic ratio were compared between the two groups.

RESULTSMean number of retrieved lymph node of the label group was higher as compared to the control group (22.3±4.2 vs. 15.4±3.5, P<0.05). The total number of retrieved lymph node was 725 in the label group and 478 in the control group. Among them, lymph node < 5 mm accounted for 4.6% (33/725) in the label group, which was higher than 2.0% (10/478) (P=0.025) in the control group. The number of black stain label lymph node was 412, with black stain ratio 56.8% (412/725) in the label group. Metastatic ratio of black stain nodes was significantly higher than that of non-stain nodes [28.6% (118/412) vs. 19.5% (61/313), P=0.005].

CONCLUSIONSThe technique of carbon nanoparticles labeled lymph node staining in curative laparoscopic resection for colorectal carcinoma is easy and effective, which can increase the retrieved number of lymph nodes, especially for nodes < 5 mm. The black stain lymph nodes indicate higher risk of metastasis.
