Objective To analyze the value of open tension -free hemiorrhaghy ( OTFH) and laparoscopic totally extraperitoneal prosthesis ( LTEP) repair in patients with bilateral inguinal hernia .Methods A retrospective method was used to compare the clinical data of 115 patients with bilateral hernias , of which 61 cases received LTEP and 54 cases underwent OTFH , from June 2011 to December 2013, in our hospital .Results The mean operative time of LTEP group (88.2 ±15.6 min) was longer than the OTFH group(75.7 ±21.6) min (p<0.05).The dura-tion of hospitalization in LTEP group(2.6 ±1.1) day was shorter than OTFH group(4.2 ±2.1) d (p<0.05).Hos-pitalization expense of LTEP group (12 012.0 ±2 325.2) yuan was higher than the OTFH group (9 291.3 ±2 010.1) yuan (p<0.05).The incision pain by VAS points was gradually decreased in 24 hours, 48 hours, 72 hours after op-eration, and LTEP group was significant lower than OTFH group in the same time point .In LTEP group 3 case had laceration of peritoneum but turn to no other prosthesis , and 2 cases had acute urinary retentions .11 acute urinary re-tentions occurred in OTFH group , and 2 cases had chronic pain in inguinal area and 1 cases of fat liquefaction .No recurrence was found during a follow -up period of 6 to 24 months in both of 2 groups .Conclusion Both LTEP and OTFH are safe and accessible techniques for patients with bilateral inguinal hernia .OTFH is feasible, and has short process and low cost which is suitable for primary hospitals to carry out .OTFH has the advantages of little trauma , faster postoperative recovery and less complications which is worth promoting in future .

Objective To study the proliferation inhibition effect by silencing PLCε gene expression with RNA interference in BIU-87 cells. Methods The specific short hairpin RNA recombinant plasmids were constructed by gene clone technology.The expression level of PLCε protein and mRNA were detected by Western blot and RT-PCR respectively after transfected recombinant plasmids into BIU-87 cells.The influence on proliferation was check by MTT.The changes of proliferating cell nuclear antigen(PCNA)were analyzed by immunocytochemical method,and the distribution of cell cycle was analyzed using flow cytometry. Results After transfected with the specific recombinant plasmids,PCNA expression was decreased 33.08%,and the analysis of cell cycle indicated that cells of G0/G1 phase were increased comparision with(40.75±2.30)%and(40.00±1.76)0A,and its G2/M phase cells(8.16±0.51)%were decreased strikingly compared with group control(31.20±1.76)%and group NP(35.94±1.58)%.Cells were blocked at G0/G1 phase,the cell proliferation was inhibited obviously. Conclusion PLCε may play an important role in proliferation of bladder cancer cells,which could be a potential target of biological treatment on bladder cancer in the future.
