Objective:To establish the quality evaluation method of Prunellae spica dispensing granules based on three quality indexes of standard decoction. Methods:Fourteen batches of Prunellae spica were collected from different habitats. According to technical requirements, fourteen batches of Prunellae spica standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The fingerprints of Prunellae spica standard decoction and formula granules were established by Ultra High Performance Liquid Chromatography (UPLC). The similarity values of fingerprints between dispensing granules and standard decoction were calculated. The content and transferring rate of Rosmarinic acid were determined and calculated. Results:The average paste-forming rate of Prunellae spica was (12.59±2.32)%. The paste-forming rates of the three batches were 11.14%, 10.78% and 10.39% respectively. The average content of Rosmarinic acid in standard decoction was (18.99±9.74)mg/g. The average transferring rate was (60.58±7.87)%. The contents of three batches were 7.40 mg/g, 7.49 mg/g and 7.09 mg/g. The transferring rates were 52.06%, 50.10% and 50.40% respectively. Nine common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, two of which were identified as Rosmarinic acid and Caffeic acid by comparison of reference substance. The fingerprints similarity of Prunellae spica dispensing granules and standard decoction were 0.954, 0.973 and 0.952, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method could provide reference for the establishment of quality standard of Prunellae spica dispensing granules.

Objective To compare the clinical effects of interscalene brachial plexus block and superior trunk block in arthroscopic shoulder surgery with 0.25% ropivacaine. Methods 46 patients undergoing shoulder arthroscopy surgery were included and randomly divided into group ISB (n=23) and group ST (n=23). Patients in group ISB received 10 ml 0.25% ropivacaine on the lateral side of C5 and C6. Patients in group ST were treated with 5 ml 0.25% ropivacaine on both sides of the superior trunk of brachial plexus. The diaphragmatic excursion, Numerical Rating Scale(NRS), duration of the block, handgrip strength were recorded at different time. Results No statistical difference was detected between the two groups in the reduction of diaphragmatic excursion within 30 min after block (P>0.05). Compared with ISB patients, ST patients had significantly less diaphragmatic excursion at 3 h after block（P<0.05). 30 minutes after block, 8.7% patients in ISB group reached complete HDP and 52.2% patients reached partial HDP. At the same time, no complete HDP and 26.1% partial HDP were detected in ST group. 3 hours after block, patients in ST group had lower complete HDP rate (0.0% vs 17.4%) and lower partial HDP rate (39.1% vs 65.2%) than patients in ISB group. At 30 minutes and 3 h after block, the reduction of grip strength in ST group was significantly lower than that in ISB group (P<0.001). ST group had lower NRS than ISB group (P<0.05). The average block time in ISB group (8.3±1.97 )h was significantly lower than that in ST group (10.9±1.26)h (P<0.01). Conclusion Superior trunk block with 10 ml 0.25% ropivacaine is superior compared to interscalene brachial plexus block in occurrence of HDP, decrease of grip strength, postoperative pain and block duration.

Purpose: The aim of this meta-analysis was to evaluate the efficacy and safety of imidafenacin for overactive bladder (OAB) induced by benign prostatic hyperplasia (BPH) in men receiving alpha-blocker monotherapy. Methods: We performed a systematic research of the PubMed, Embase, and Cochrane Library databases, and searched for studies about alpha-blocker with or without imidafenacin treatment for OAB in patients with BPH. We also investigated the original references of the included texts. Results: Four randomized controlled trials including 779 participants with BPH (389 in the alpha-blocker+imidafenacin group and 390 in the alpha-blocker only group) were studied. The main efficacy endpoint was the Overactive Bladder Symptom Score, which showed a mean difference of -1.88 (95% confidence interval, -2.32 to -1.44; P<0.00001), suggesting that alpha-blocker and imidafenacin treatment was effective in treating men with OAB. As other primary efficacy end points, the International Prostate Symptom Score (IPSS) total score (P=0.47), the IPSS storage symptom score (P=0.07), the IPSS voiding symptom score (P=0.60), and the IPSS quality of life score (P=0.18) indicated that 2 methods had no significant differences in treating men with OAB. In terms of safety, which was assessed using postvoid residual volume (P=0.05) and maximum flow rate (P=0.53), the analysis suggested that combination treatment was very well tolerated. Conclusions This study suggested that imidafenacin plus alpha-blocker was an efficacious and safe treatment for OAB symptoms in BPH patients.

OBJECTIVETo compare the clinical efficacy of the lymph node dissection patterns of the reverse and the traditional cabbage in hand-assisted laparoscopic D2 radical gastrectomy (HALG).

METHODSFrom December 2010 to October 2013, 194 patients with HALG in Chengdu Military General Hospital were enrolled in this study. According to the pattern of lymph node dissection, 108 patients were performed with the reverse procedure which took spleen as starting point, from left to right, and 86 patients were performed with the traditional cabbage procedure which took the abdominal cavity as the center, from both sides to middle. A retrospective comparative analysis was made on the intra- and post-operative data between the two groups.

RESULTSAll the patients were successfully performed with HALG, and no peri-operative death occurred. There were no significant differences in the incision length [(7.0 ± 0.2) cm vs. (6.9 ± 0.3) cm], the operative time [(170.9 ± 33.8) minute vs. (174.6 ± 22.4) minute], dissected lymph node number (17.6 ± 7.5 vs. 17.1 ± 5.8) and post-operative complications [(6.5%(7/108) vs. 8.1%(7/86)] between the reverse group and cabbage group (all P>0.05). However, less blood loss [(204.6 ± 98.2) ml vs. (259.1 ± 122.6) ml, P<0.01] and shorter postoperative hospital stay [(9.0 ± 1.7) day vs. (10.5 ± 4.0) day, P<0.01] were observed in reverse group as compared to cabbage group. During 1 to 6 months follow-up, no death case was found in reverse group, while 1 case died due to upper gastrointestinal bleeding 48 days after operation in cabbage group.

CONCLUSIONEfficacy is similar between the two HALG procedures in lymph node dissection, while reverse procedure has certain advantages, such as less blood loss and faster recovery.
