Objective To analyze the expression of long non-coding RNA ( lncRNA) in renal clear cell carcinoma ( RCCC ) , the association of lncRNA with RCCC, as well as the role of lncRNA in the diagnosis and treatment of RCCC.Methods Forty fresh RCCC tissues and their normal adjacent tissues were collected from March 2012 to June 2013, and total RNA was extracted using Trizol reagents, purified and tested by denaturing agarose gel electrophmesis and NanoDrop 1000.Through Arraystar Human LncRNA Microarray, the different expression of lncRNA between RCCC and normal adjacent tissues was screened. RT-qPCR was used to verify the expression of lncRNA in 40 pair RCCC tissues and normal adjacent tissues. The receiver-operating characteristic ( ROC ) curve was adopted to verify the diagnostic efficiency of the selected lncRNA.Results LncRNA expression profile showed 1 787 lncRNA with expression alteration in two fold or above, up-regulated and down-regulated candidate lncRNAs were 941 and 846 respectively. Compared with the adjacent tissues, NR_034095 and NR_038974 were up-regulated in RCCC, and ENST00000571724 and ENST00000566575 were down-regulated, which were consistent with the microarray analysis.By the ROC curves of NR_034095, NR_038974, ENST00000571724 and ENST00000566575 to discriminate the RCCC from normal adjacent tissue, the area under curve was 0.928 ( 95%CI 0.873 -0.984), 0.759 (95%CI 0.647-0.871), 0.833 (95%CI 0.747-0.919) and 0.887 (95%CI 0.815-0.959 ) , respectively.Conclusions NR _ 034095, NR _ 038974, ENST00000571724 and ENST00000566575 are significantly differently expressed in RCCC.The different expressed lncRNA might be closely related to the process of RCCC, and may be used as a new candidate target for molecular diagnosis and gene therapy of RCCC.

Objective To investigate the effects of combined epidural block with inhalation - intravenous general anesthesia (GE) on stress response in thepatients for laparoscopic radical colonectomy. Methods Twenty-eight ASA I-II patients scheduled for laparoscopic radical colonectomy were randomly divided into group GE and inhalation-intravenous general anesthesia group(group G) with 14 cases each. In group GE, epidural blocks were operated before induction, MAP,ECG ,HR,SpO2 and PETCO2 were observed and recorded at such point-time: pre-pneumoperitoneum and 1,2,3 h after pneumoperitoneum. Arterial blood-gas analysis ,noradrenaline(NE) and adrenaline(E) were also measured at the same time; Group G was the same as group GE except for no epidural block and extra fentanyl. Results The level of stress response hormones(NE and E) of post- pneumoperitoneum 1,2,3 h were increased VS those of pre-pneumoperitoneum in both groups, and group G was significant (P

Objective To study the value of the technique of "Push-pull traction-relax homingrepeatedly confirmed" in the prevention of bile duct injury in LC. Methods From March 2001-August 2009, we applied this technique in 4800 cases of LC. The technique of "Push-pull traction" showed the structures of in the Calot's triangle. The technique of "relax homing" was to restore the cystic duct,hepatic duct and common bile duct to their original anatomical positions. The technique of "repeatedly confirmed" repeatedly identified the positions of the cystic duct, the common hepatic duct and the common bile duct. Results There was no bile duct injury. Conversion to open surgery happened in 118patients due to difficulties in identifying the Calot's triangle structures, bile duct stones, gallbladder cancer, and gallbladder-duodenal fistula. Conclusions The "Push-pull traction-relax homing-repeatedly confirmed" technique could effectively prevent bile duct injury in LC. The method is simple, easy to master and worthy of promotion.

Endoplasmic reticulum plays a key role in both basic structure formation and function performance of microenviron-ment.
