To compare the efficacy and safety of physical thermal ablation (PTA), including radiofrequency ablation (RFA) and microwave ablation (MWA), combined with sorafenib and physical thermal ablation alone for the control and treatment of hepatocellular carcinoma (HCC) according to the available literature.
Comprehensive searches were performed on PubMed, Embase, CNKI, the Cochrane Library, China Biomedical Literature Database (known as CBM), Weipu Journal, and Wanfang Database. Meta-analysis was performed using Revman 5.3 software.
A total of 15 studies, consisting of 2,227 HCC patients, were selected and included in this meta-analysis. Compared with the RFA-alone group, the patients in the RFA+sorafenib group had longer 1-, 2-, and 3-year overall survival (all
0.05), better overall efficacy (
<0.0001), longer radiofrequency interval (
<0.001), and lower 2-year recurrence rate (
=0.02). The 1-year overall survival (
=0.003) and overall efficacy (
=0.002) of the MWA+sorafenib group were also higher than those of the MWA-alone group. The incidences of adverse reactions in the RFA+sorafenib group, such as hand-foot skin reactions (
<0.001), diarrhea and constipation (
=0.0001), hypertension (
=0.009), and alopecia (
<0.001), were significantly higher than those in the RFA-alone group.
RFA or MWA combined with sorafenib has produced a better therapeutic effect on HCC than physical thermal ablation alone; however, adverse reactions have been obvious. It is necessary to evaluate the safety of combination therapy, and pay close attention to the adverse reactions that develop in patients.

Drug-resistant DNA mutations of the hepatitis B virus (HBV) affect treatment response in chronic hepatitis B patients. We have established a new, sensitive, specific, accurate and convenient real-time PCR method to detect HBV mutations quantitatively.
Blood samples were collected from patients showing viral breakthrough, primary nonresponse, or poor response during treatment, and mutations were detected via direct sequencing to assess our method. A plasmid containing the M204V mutation was synthesized and standard curves plotted.
The determination coefficient for linear correlation between Ct and log plasmid copy numbers was 0.996, where Ct value was -3.723log (DNA concentration) +48.647. Coefficients of variation indicated good reproducibility. Correctness was within tolerable bias. Limit of detection was 10
copies/mL. Specificity, accuracy, positive predictive value and negative predictive value were 92.86%, 100%, 96.88%, 100% and 94.74%, respectively.
These results show that our method can be used to detect HBV M204V mutations with the advantages of sensitivity, specificity and efficiency, providing a new choice for monitoring drug resistance.

Firstly, the transport phenomena analysis is performed to select the suitable intensified unit. The reactive distillation is selected and used in esterification - transesterification process and hydrolysis - esterification process. The optimum condition of reactive distillation in esterification - transesterification is achieved when the methanol is fed at the 3rd stage of the 4-stage column and the liquid holdup is maintained at 6 m3. The intensified esterification - transesterification process offers higher biodiesel yield and consumes less energy compared with the intensified hydrolysis - esterification process. The economic analysis shows that the intensified esterification-transesterification process is found to be economically feasible. Finally, environment assessment based on life cycle analysis (LCA) indicates that the environmental impact of both processes are similar.Primary tumors of the epididymis are mostly benign in nature, and the most common type is adenomatoid tumors followed by leiomyomas. Leiomyoadenomatoid tumors are very rare benign epididymal neoplasms composed of two components gland-like structures lined by cuboidal cells and bundles of smooth muscle components. The goal of treatment is testicular-preserving surgery. A preoperative and intraoperative evaluation plays an important role in proper management. To the best of our knowledge, few cases have been reported in the literature. We report a case of a right epididymal tail leiomyoadenomatoid tumor in a 49-year-old male who underwent trans-scrotal exploration and tumor excision.Isolated prostate cancer metastasis to the adrenal gland is rare. We report a case of concordant high uptake in a solitary adrenal metastasis on both prostate-specific membrane antigen and fluorodeoxyglucose positron-emission tomography in a patient with castrate-resistant prostate cancer. Good initial biochemical response was achieved with laparoscopic adrenalectomy. The patient developed lymph node recurrence 12 months later, although remains asymptomatic on hormonal treatment 22 months post-operatively, in keeping with prior results for metastasis-directed therapy which can delay time to additional treatment. Application of dual tracer PET can be valuable for prostate cancer staging and guidance of metastasis-directed treatment.An acute scrotum is a common clinical scenario prompting urologic involvement. Scrotal ultrasonography with Doppler is the main imaging modality utilized for the evaluation of an acute scrotum and can help distinguish testicular torsion from epididymoorchitis, two common causes of testicular pain. Testicular infarction is a rare but potential complication of epididymoorchitis. OSI-930 We report a case of epididymoorchitis presenting with reversal of testicular diastolic flow concerning for impending testicular infarction but with a non-ischemic testis on scrotal exploration and repeat scrotal ultrasonography post-operatively.
