AIM:To evaluate the efficacy and safety of Sub-tenon's anesthesia for compound trabeculectomy with high intraocular pressure.
METHODS: Forty - six eyes ( 46 cases ) of primary glaucoma received compound trabeculectomy under Sub-tenon's anesthesia, whose preoperative intraocular pressure were higher than normal after 24 to 48h of combined medication. Both efficacy and complication of the anesthesia were studied.
RESULTS: One minute after anesthetic injection, all cases were able to achieve the effect of analgesia and eye brake. During the operation, 0 level of anesthesia effect included 35 eyes ( 76%) , 1 level of anesthesia effect included 10 eyes ( 22%) , 2 level of anesthesia effect included 1 eye(2%). Only 1 case of these patients needed to add the surface anesthetic once, and other cases were successfully operatedunder Sub-tenon's anesthesia. The total effective rate was 98%. No anesthesia complications occurred in all cases.
CONCLUSION: Sub - Tenon's anesthesia is safe, effective, simple and quick for compound trabeculectomy with high intraocular pressure.

Objective:To construct a recombinant lentivirus plasmid of RNA interference targeting (MSLN) gene and to observe its effect on MSLN expression in human ovarian cancer cell line OVCAR-3 and its effect on cell proliferation. Methods: According to the Genbank information of MSLN, four RNA interfering sequences and a negative sequence were designed and inserted into plasmid pRNAT-U6.2/Lenti and 5 kinds of plasmids were packaged: LV-MSLN-negative,LV-MSLN-shRNA1, LV-MSLN-shRNA2, LV-MSLN-shRNA3, and LV-MSLN-shRNA4; and they were used to transfect OVCAR-3 cells. Western blotting and indirect immunofluorescence were then used to investigate the interfering efficiency. The plasmid with high interfering efficiency was packaged. The cell proliferation test and clone-forming test was used to assess the changes in cell proliferation. Results: DNA sequencing showed that the sequences of 5 recombinant lentivirus plasmids were correct. Lentivirus packaging was successfully done. Western blotting analysis confirmed that LV-MSLN-shRNA4 had the highest interfering efficiency (90%). MSLN specifically bound to cytomembrane of OVCAR-3 cells. Expression of MSLN in the interfered cells (OVC-shRNA) was weaker than that in the control cells (OVC-neg,OVC). OVC-shRNA cells([11.2?1.3]?105) grew slowly compared to OVC-neg cells([20.5?2.5]?105) and OVC cells([21.9?2.3]?105) (P
