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

This study was aimed to discuss the difference of Cun-Kou six-pulse (CKSP) diagram of different diseases. The ZBOX-I Type Pulse Digital Analyzer was used to collect CKSP diagram of 30 bronchial asthma cases and 33 chronic gastritis cases. Time-domain parameter was extracted for analysis. Comparison was made by statistical methods. The results showed that there was statistical difference on time-domain parameter of pulse diagram for different diseases (P<0.05). There was statistical difference on time-domain parameter of pulse diagram between the left side and right side (P<0.05). There were statistical differences on t4 of left Cun, t4 and h5 of right Cun, t1\t4 of left Chi between bronchial asthma and chronic gastritis cases (P<0.05). It was concluded that the single-cycle pulse diagram of chronic gastritis was wider but no higher than that of bronchial asthma. The systole phase of single-cycle pulse diagram of bronchial asthma occupied greater proportion than that of chronic gastritis. There was difference on Cun of time-domain parameter in pulse diagram between bronchial asthma and chronic gastritis. It was consistent with the theory of Cun-Kou sub-designated zang-fu organs, which was “left Cun designates heart, right Cun designates lung.” However, there was no further explanation on functional differences between the spleen and stomach. The mechanism of pulse difference on the left and right side still required further illustration.
