Objective To detect the changes of cell proliferation and IFN-γsusceptibility of human pancreatic can-cer cells after suppressor of cytokine signaling-1 (SOCS1) gene silencing, and to explore the SOCS1 as the target of anti-tu-mor therapy through enhancing the function of IFN-γ. Methods Western blot assay, PCR and real-time PCR were used to verify the down regulation of SOCS1 in human pancreatic cancer cell (PANC1) after transfection;subsequently, PANC1 was stimulated with IFN-γ. Western blot assay was also used to detect the expression of signal transducers and activators of tran-scription (STAT)1 and phosphorylation STAT(pSTAT)1;and the change of IFN-γsusceptibility was detected by MTT assay. Real-time PCR was used to detect the mRNA of interferon regulatory factor-1(IRF-1). Flow cytometry was used to detect the cell cycle. Results The expression levels of SOCS1 mRNA and protein were significantly decreased in small hairpin SCOS1 (shSOCS1) transfected PANC1 cells. After the silence of SOCS1, the expression levels of IRF-1 and pSTAT1 in-creased significantly (P<0.05), and the median inhibitory concentration(IC50)of IFN-γfor PANC1 cells decreased signifi-cantly (P<0.01). The cell count of shSOCS1 cells dropped significantly compared with that of control group after the SOCS1 silencing for 72 hours (P<0.05). The cell cycle arrest was promoted at the G0/G1 phase, but the percentage of cells in S phase and G2/M decreased compared to that of control groups (P<0.05). Conclusion After the inhibition of SOCS1 gene expression, the proliferation ability of human pancreatic cancer cell line PANC1 decreased, and the sensitivity of PANC1 cells to IFN-γwas enhanced.

Internal mammary nodes are part of the first stop of mammary gland lymphatic drainage.It plays an important role in the process of occurrence and development of breast cancer.Whether irradiation internal mammary nodes or not is still a larger controversy.At present,for the early stage patients,the efficacy of internal mammary lymph node irradiation is not clear.For the patients with positive axillary lymph nodes,inboard or central quadrant lesions,postoperative radiotherapy of internal mammary nodes has a certain value.

Objective To investigate the indications,approaches,and essentials of cranio-orbital surgeries for orbital apextumors.Methods The clinical data of 48 patients with orbital apextumors treated by refined transcranial orbitotomy through superolateral approach were analyzed retrospectively,34 tumors were excised with orbitoptenonal approach,while 14 tumors were excised with orbltotrontal approach,orbitozygomatic approach,or zygomatic-ptefional approach.Results Of the 48 orbital apextumors,33 cases were totally resected,7 cases were subtotally resected,and 6 cases were partly resected.The other 2 cases were taken biopsies.The optic functions improved or retained in 40 cases,7 cases suffered from eye-moving disfunction or visual-acuity declines,and 1 case suffered from hemiparalysis.Conclusions Tumors in the posterior and apex part of the orbit,or tumors extended from the orbit to the cranial,can be well treated through transcranial approach.Appropriate methods may help to bring maximum convenience to exposure and excision of the lesion,and to conserve the functions.Unnecessary injuries could be avoided as well.

Objective To evaluate the prognosis and safety of long-term oral Branched-Chain Amino Acids (BCAAs) for patients with cirrhosis.Methods Randomized controlled trials (RCTs) were identified from CBM (between January 1978 and September 2013),CNKI (between January 1979 and September 2013),PubMed (between January 1970 and September 2013),EMBASE (between January 1970 and September 2013),and Cochrane Library (issue 4,2013).Publications of the RCTs on the treatment of cirrhosis with oral BCAAS were included and analyzed according to the criteria of Cocbrane handbook.Results Six RCTs involving 1 047 patients were included.The results showed that oral BCAAs improved the event-free survival when compared with the control group [RR =1.13,95% CI =(1.05,1.23),P =0.001].BCAAs supplements had no effect on mortality or had no definite effect on the deteriorative rate of minimal hepatic encephalopathy (MHE) or quality of life (QOL).As reported in some trials,the main side effects of BCAAs were gastrointestinal symptoms.Conclusions Long-term oral BCAAs may improve event-free survival in cirrhotic patients.However,no definite conclusion can be made without evidences from larger,randomized,double-blind,placebo-controlled,and multicenter trials.
