Objective To review the efficacy and safety of brucea javanica oil in the adjuvant therapy of primary hepatocellular carcinoma (HCC).Methods China National Knowledge Infrastructure (CNKI),China Biology Medicine (CBM),VIP,Wanfang database,Pubmed,Web of Science,ScienceDirect,and Cochrane Library were searched from their inception to December 2015.Then contact with the field experts and correspondence authors for gray literature.Two reviewers independently searched the databases,performed data extraction,and appraised the publications.The Reviewer Manager 5.3 software was employed for data analysis.Results Fifteen clinical trials with 1 128 HCC patients were included.Meta-analysis confirmed that the brucea javanica oil group,compared to the control group,was more advantageous to reduce the incidence of postoperative fever,bone marrow suppression,and gastrointestinal reaction.In addition,it might reduce the level of alpha fetoprotein (AFP),enhance immunity,and improve clinical symptoms.However,more evidence would be needed to support these results.Conclusions Brucea javanica oil is considered to reduce toxicity and increase efficiency in the adjuvant therapy for the HCC,but more high quality,multi-center,large sample,randomized,double-blind clinical trials are also needed for supporting this view.

Objective To conclude the characterization of renal cellular carcinoma(RCC)with contrast enhanced ultrasound.Methods Seventy patients(seventy-two nodules)with RCC,which were confirmed by operation and biopsy underwent conventional ultrasound and contrast-enhanced ultrasound(CEUS).Microbubble agents SonoVue and contrast pulse sequence(CPS)were used.The conventional uItrasonographic characterization and the enhancement patterns of lesions were analyzed.Results On baseline sonography,the numbers of lesions that showed hypoechogenicity,isoechogenicity,and hyperechogenicity were 44.4%(32/72),25.0%(18/72)and 30.6%(22/72),respectively.Only 28 lesions(38.9%)showed flow signals on color Doppler sonography,the mean maximum velocity of which WSS(43.7±16.8)cm/s(range,24.8-95 cm/s),and the mean resistance index was 0.635±0.11(range.0.52-0.83).Sixty-three(87.5%)lesions were hyper-vascular in cortical phase.Among them forty-eight(76.2%)lesions were hypo-enhanced,and fifteen(23.8%)lesions were still hyper-vascular in late phase.The remaining nine hypervascular nodules in cortical phase were still hyper-enhancing in late phase.Fifty-four(75.0%)lesions were inhomogeneous enhancement.and pseudocapsule was observed in sixty-three(87.5%)RCC lesions.Conclusions The enhancement patterns of RCC are characteristic,and CEUS may be helpful in differential diagnosis of focal renal lesions.

The treatment of mediastinal tumor has always been a clinical difficulty due to its complex anatomical location and many important organs.Compared with traditional local treatment,endobronchial ultrasound guided laser multi-point ablation of mediastinal tumors has many advantages,including real-time monitoring of ablation range and effect,avoidance of damage to normal tissue and organs,few side effects and good tolerance.This article describes the standard operating procedure for endobronchial ultrasound guided laser multi-point ablation of mediastinal tumors.
