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.

Objective To investigate the three-dimensional structure of normal male canine prostat- ic duct and acinus system,and to study the mechanism of intraprostatic urinary reflux(IPUR)resulting from high pressure of the posterior urethra by experiment.Methods Using scanning electron microscopy (SEM)and corrosion casting methods,high pressure of the prostatic urethra was produced based upon IPUR in normal male canines.Acrylonitrile-butadiene-styrene(ABS)casting solution was injected into 8 Beagle canines'normal prostates to induce intraprostatie resin solution reflux.Results Six casting molds of nor- real canine prostate specimens were obtained,and the casting failed in 2.By corrosion and casting treatment, the prostate appeared to consist of several glandular lobes.The columnar apophyses of glandular surface were observed.The most glandular ducts pointed outward from urethral peristome.Each glandular duct system was made up of many bifurcated branches from the bough as a duct tree.More than 90% of the bifurcations were Y-shaped,and 6 bifurcated branches were rarely seen.The tip of the duct was vesicular.The diameter and length of the bough were(0.37?0.14)mm and(1.14?0.04)mm,respectively.The intersectional angle of urethra and peripheral glandular duct was the biggest.Peripheral glandular duct was perpendicular or con- verse to urinary flow.Peripheral glandular aeinus appeared elliptic and velvet.The mesh-like and crater-like depressions were shown on the surface of central glandular aeinus.Ejaculatory ducts independently and branchlessly entered the urethra.Conclusions The resin corrosion casting methods combined with SEM can clearly show the three-dimensional structure of normal male canine prostatic duct and acinus system. IPUR may easily occur in the peripheral glands from the morphological view.It is suggested that prostatitis occurs more commonly in peripheral glands,confirming a fact that high pressure of the posterior urethra can induce IPUR.

The average life expectancy in Macau is ranking the second in the world, the consumption of fresh medicinal plants is a profound culture in Macau. The paper focus on the distribution of the antioxidant herbs, a comprehensive investigation and analysis the amount of the plant resources was carried out. The antioxidant activity of alcohol extracts was determined by using the DPPH method, and six kinds fresh herbs with high antioxidant free radical activity were screened out. Reference to adult daily dose of vitamin C, it is calculated that the daily dose amount of fresh herbs is less than 200 g. For the expected shortage of resources and the ecological status of Macau, we give some suggestions of herbal introduction in population ecology reconstruction.

The clinical therapeutic effect of acupoint catgut-embedding for simple obesity was systemically analyzed to provide reference and assistance for its clinical treatment and research. By searching in the CBM, CNKI, VIP, Wanfang, Pubmed, Springer and Medline databases, clinical randomized controlled trials (RCT) of acupoint catgut-embedding for simple obesity published from Jan, 2009 to July, 2013 were collected while Revman 5. 2 software was applied to perform the Meta-analysis. Totally 19 articles were acquired with 1 658 cases involved. The effective rate was selected as primary outcome measure in 19 articles. The Meta-analysis was performed among homogeneous researches. The results indicated that compared with other therapies, pooled OR of acupoint catgut-embedding was 2.45 with 95% CI [1.81, 3.32]; in the test for overall effect, Z = 5.81, implying the efficacy difference of two therapies was significant in the treatment of simple obesity (P < 0.01). In subgroups analysis, in the event of treatment session with more than 3 months, compared with other therapies, pooled OR of acupoint catgut-embedding was 2.61 with 95% CI [1.53, 4.46]; in test for overall effect, Z = 3.51, implying the efficacy difference of two therapies was significant in the treatment of simple obesity (P < 0.01); in the event of treatment session with less than 3 months, compared with other therapies, pooled OR of acupoint catgut-embedding was 2.38 with 95% CI [1.65, 3.44]; in test for overall effect, Z = 4.46, implying in the treatment of simple obesity the efficacy difference of two therapies was significant (P < 0.01). Compared with electroacupuncture, OR of acupoint catgut-embedding was 1.79, 95% CI [1.08, 2.95] (P = 0.02). Compared with acupuncture, OR of acupoint catgut-embedding was 1.89, 95% CI [1.16, 3.09] (P = 0.01), which explained that compared with electroacupuncture and acupuncture, the efficacy of acupoint catgut-embedding was significantly different. In a word, the clinical efficacy of acupoint catgut-embedding is superior to other therapies in the treatment of simple obesity.

A pilot-scale research on purification of odorous gas emitted from wastewater treatment plant using a biofilter was conducted. The aim of this study is to check on the performance of biofilter running in various conditions and the effect of pH fluctuations on the performance of biofilter. The relation between distribution of microorganism and removal of odorous gases were also discussed here. The experimental results show that the predominant odor-causing gas can be efficiently eliminated by a biofilter inoculated with deodoring microorganism which were isolated previously. Moreover the biofilter had been proved having good tolerance to shocking loads of pollutant and can operate well in the condition of low pH.

Objective To evaluate the role of transesophageal echocardiography (TEE) in perioperative period of pediatric patients with congenital heart disease (CHD).Methods From July 2011 to December 2012,TEE was used in 393 pediatric patients(≤ 14 years) with congenital heart disease in perioperative period.We make a retrospective review with the clinical data of these cases.Results Operative schemes or therapeutic schedules of 60 patients(15.3％) were altered according to TEE.By preoperative TEE,the diagnosis of transthoracic echocardiography (TTE) of 4 cases(1.0％) were amended,4 cases (1.0％) were complemented,and 4 cases (1.0％) got the auxiliary diagnosis,among which operative schemes of 11 cases (2.8％)were altered.During the operate,29 cases(7.4％) found residual problems,11 cases(2.8％) got the auxiliary diagnosis.By postoperative TEE,7 cases(1.8％) found residual problems,1 case(0.3％) got the auxiliary diagnosis.Complications occurred in 9 cases(2.3％) of the 393 patients.Oral and pharyngeal mucous membrane bleeding occurred in 7 cases (1.8％),inadvertent tracheal extubation in 2 cases(0.5％).Conclusion TEE plays an important role in confirming preoperative diagnoses,formulating surgical plans,evaluating immediate operative results,identifying patients with residual defects and guiding the therapeutic schedule in perioperative period of pediatric patients with congenital heart disease.
