This meta-analysis aimed to comprehensively assess the efficacy and safety of hepatic resection combined with radiofrequency ablation versus hepatic resection (HR) alone for the treatment of multifocal hepatoeellular carcinomas (HCC).A literature search was conducted from the database including MEDLINE,Embase,Cochrane Central Register of Controlled Trials (CENTRAL) and China Biology Medicine (CBM) disc.The primary outcomes included the 1-,3-,5-year overall survival (OS) and disease-free survival (DFS) rate.The secondary outcomes contained the intraoperative parameters and postoperative adverse events (AEs).These parameters were all analyzed by RevMan 5.3 software.After carefully screening relevant studies,four retrospective studies of high quality involving 466 patients (197 in the combined group and 269 in the HR group) were included in this study.The pooled results showed that the 1-,3-,5-year OS rate in the combined group were comparable with those in the HR group (OR=0.77,0.96,0.88;P=0.33,0.88,0.70,respectively).Similarly,there was no significant difference in 1-,3-,5-year DFS rate between the combined group and the HR alone group (OR=0.57,0.83,0.72;P=0.17,0.37,0.32,respectively).And the intraoperative parameters and postoperative AEs were also comparable between the above two cohorts.However,two included studies reported that tumor often recurred in the ablation site in the combined group.The present meta-analysis indicated that the HR combined with RFA could reach a long-term survival outcome similar to curative HR for multifocal HCC patients.And this therapy may be a promising alternative for these patients with marginal liver function or complicated tumor distribution.Furthermore,high quality randomized controlled trials (RCTs) are imperative to verify this conclusion.

The chromatographic fingerprint of Gastrodia elata Bl. (Tianma) was developed to compare the quality of Tianma samples from different habitats and processing methods. The above analysis method was established by HPLC-DAD technique. And an HPLC method was used to analysis the contents of gastrodin (GAS) and p-hydroxybenzyl alcohol (HBA) in Tianma from different habitats and processed methods. Experiments of chromatographic fingerprint analysis were carried out with a Zorbax XDB C18 column (250 mm x 4.6 mm, 5 microm). The mobile phase consisted of acetonitrile and 0.1% aqueous acetic acid in gradient elution mode. The column was maintained at 25 degrees C. Detection was set at 270 nm. The mass spectra were recorded using as ESI source in the negative mode with ion spray voltage at 3500 V, source temperature at 335 degrees C, gas spray at 8.3 kPa and gas flow rate at 9 L x min(-1). The HPLC methods of quantitative analysis were the same as those of chromatographic fingerprint analysis except the mobile phase, which consisted of acetonitrile and 0.1% aqueous acetic acid in isocratic elution mode with the ratio of 4.5 to 95.5 (v/v). Data of chromatographic fingerprint were analyzed by the "similarity evaluation system for chromatographic fingerprint of TCM (Version 2004 A)" software to compare the quality of Tianma. Samples from different habitats with the same processing method were of high similarity, though a few samples showed evident difference in fingerprint graphics. For Tianma samples with different processing methods, the contents of common peaks were different and the processing method of freezing to dry was better than others. With HPLC-MS technique, 8 major common peaks in the fingerprint of Tianma were identified by their MS spectra and comparison with the reference standards. The results of similarity analysis for chromatographic fingerprint were basically consistent with those of quantitative analysis. The established HPLC-DAD/MS methods can be used to evaluate the quality of Tianma.

The industrialization chains and their products, which were formed from the process of the production of medicinal materials-prepared drug in pieces and deep processed product of Chinese material medica (CMM) resources, have generated large benefits of social and economic. However, The large of herb-medicine castoff of "non-medicinal parts" and "rejected materials" produced inevitably during the process of Chinese medicinal resources produce and process, and the residues, waste water and waste gas were produced during the manufactured and deep processed product of CMM. These lead to the waste of resources and environmental pollution. Our previous researches had proposed the "three utilization strategies" and "three types of resources models" of herb-medicine castoff according to the different physicochemical property of resources constitutes, resources potential and utility value of herb-medicine castoff. This article focus on the conversion efficiency of resources model and analysis the ways, technologies, practices, and application in herb-medicine cast off of the conversion efficiency of resources model based on the recycling economy theory of resources and thoughts of resources chemistry of CMM. These data may be promote and resolve the key problems limited the industrialization of Chinese material medica for long time and promote the realization of herb-medicine castoff resources utilization.

BACKGROUNDInside out transobturator vaginal tape (TVT-O) and tension-free vaginal tape (TVT) are predominant surgical treatments for female stress urinary incontinence. This meta-analysis evaluated the complications and cure rates of TVT-O versus TVT.
METHODSA comprehensive literature search was conducted according to the Cochrane Collaboration methodology to identify randomized controlled clinical trials with no language restriction. Two authors independently assessed papers for eligibility and methodological quality. Estimates were measured by relative risk with 95% confidence intervals. Outcome measures were objective cure, subjective cure and complications. Quality rating for each outcome of the meta-analysis and recommendations were performed by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.
RESULTSTwenty randomized controlled trials met the inclusion criteria, and a pooled estimate of effectiveness and complications was made. Relative risks with 95% confidence intervals for pooled effects under the fixed effects model were: 0.20 (0.09 - 0.45), for bladder injury, 0.37 (0.16 - 0.86) for hematoma, and 2.35 (1.57 - 3.51) for postoperative pain, suggesting an 80% risk reduction of bladder injury, 63% risk reduction of hematoma, and a 1.35% risk elevation for postoperative pain with TVT-O. There was no significant difference between complications of urinary tract infection 1.14 (0.78 - 1.65), lower urinary tract symptoms 1.60 (0.67 - 3.79), recatheterization 0.93 (0.59 - 1.44), and tape erosion 0.90 (0.48 - 1.67), total objective cure rate 1.06 (0.39 - 2.84) and for the subjective cure rate 0.98 (0.93 - 1.04). The quality rating for each outcome and recommendations was high for objective cure, bladder injury, hematoma, lower urinary tract symptoms, and tape erosion and moderate for subjective cure, pain, and urinary tract infection.
CONCLUSIONSTVT-O is associated with a reduced risk of bladder injury and hematoma and an elevated risk of postoperative pain. Other complications, including tape erosion, urinary tract infection, lower urinary tract symptoms, and recatheterization, are similar to those of TVT.
