[Objective] To observe the clinical efficacy of treatment on Frequent Postoperative Posner-Schlossmann syndrome in cataract intraocular lens using Chinese medicine with the effect of tonifying the liver and kidney, nourishing yin and suppressing hyperactive yang.[Methods] 46 cases of Posner-Schlossmann syndrome were randomly divided into two groups, one was the Chinese Medicine group ,in which al cases were treated with Chinese herbs and local eyedrop at the time of first onset after operation; another was the control group, in which al cases were treated with local eyedrop. [Results] Within two years after treatment, compared with the control, in the Chinese Medicine group, the cases of recurrence of Posner-Schlossmann syndrome were obviously decreased. [Conclusion] Chinese medicine with the effect of tonifying the liver and kidney, nourishing yin and suppressing hyperactive yang shows definite effect on postoperative Posner-Schlossmann syndrome, it can decrease the occurrence frequency of number.

Objective To observe the efficacy of growth hormone ( GH) co-treatment in poor responders undergoing IVF-ET.Methods To analyze all the ovaries low response patients treated by IVF/ICSI,80 cases were ran-domly divided into two groups:40 patients in GH group were given GH along with Gn daily until the HCG administra-tion.40 patients in the control group received the same treatment protocol except the GH co -treatment.The catching spawn number and MⅡova,fertile rate,the number of perfect embryos ,pregnant rate were observed .The serum con-centrations of IGF-I,IGFBP-3 were detected by ELISA and compared between the two groups .Results The number of oocytes retrieved ,number of MII oocytes ,cleavage ,number of embryos available of GH group were increased without statistical significance(all P>0.05 ).The serum IGFBP-3 level of 2 groups had no statistical significance .The fertile rate,pregnant rate ,serum IGF-I level were significantly higher in GH group than those in the control group ( all P<0.05).Conclusion GH co-treatment in poor responders could improve the outcome of IVF-ET,which imply that GH could improve the quality of oocytes and embryos related to the elevated IGF-1 level in serum .

Objective To investigate G. Pentaphyllums influence on the activity of glutathione peroxidase (GSH-PX) and catalase (CAT) in the skin of hireless photoaging mice, as well as the content of hydroxyproline (HYP). At the same time, G. Pentaphyllum's effect on the hireless photoaging mice was studied. Methods Healthy KM hireless mice were randomly divided into five groups. A skin photoaging model was established by G. Pentaphyllum administration. The changes of the activity of GSH-PX, CAT and the contents of dermal hydroxyproline in the skin were then measured by biochemical methods in each group of the experiment. Results In the model group, the activity of GSHPX, CAT and the content of HYP of skin were all decreased significantly (P＜0. 05). And there were different degrees of improvements in those of the herb given groups. Conclusion G. Pentaphyllumhas the protective effect on the skin of the photoageing in the hairless mice. The mechanism may be that G. Pentaphyllum could inhibit the oxidative damages of ultraviolet and skin photoaging by increasing the synthesis of collagen in skin.

Objective To observe the expressions of Akt and ERK phosphorylation in abdominal aortic aneurysm of rat model, and explore the pathogenesis of abdominal aortic aneurysm. Methods The rat model of abdominal aortic aneu-rysm was established. The diameter of abdominal aorta was measured and the extended rate of the aorta was calculated. HE staining was used to observe the change of pathology. Immunohistochemistry and Western blot methods were used to detect the expressions of Akt and ERK phosphorylation in the level of protein. Results The dilation of aorta was significantly high-er in abdominal aortic aneurysm group than that of saline group and normal group (P＜0.05). HE staining showed structural disorder and inflammatory cell infiltration in abdominal aortic aneurysm group. The results of immunohistochemistry and Western blot results showed that phosphorylation of Akt expression was significantly higher in abdominal aortic aneurysm group than that of saline group and normal group (P＜0.05). There was no significant difference in phosphorylation of ERK expression between three groups (P>0.05). Conclusion PI3K/Akt signaling pathway may be involved in the development of abdominal aortic aneurysm.

Objective:To observe the stability and sensitivity of transcription mediated ampliifcation (TMA) system, and to compare it with real-time reverse transcription polymerase chain reaction (RT-PCR) in amplifying serum HCV RNA in HCV infected patients. Methods: TMA system was established by moloney murine leukemia virus (MMLV) reverse transcriptase, T7 RNA polymerase and 2 speciifc primers ifrstly,and then its stability and repeatability were compared at different storage temperatures by the correlation change of HCV RNA amplification curve. The sensitivity difference between TMA and RT-PCR was evaluated by amplifying a group of 10-fold diluted HCV RNA samples which were transcribed in vitro. A total of 101 serums of chronic HCV infected patients were measured by TMA system and RT-PCR to observe the positive rate and their correlation. Linear correlation and linear regression were used to observe the correlation of the two methods. Results:TMA system was successfully established. TMA system was not stable when stored at 20℃ (placed for 24 hours only), but it was stable for 6 days when stored at 4℃ or within 6 months when stored at-20 ℃. Compared with RT-PCR whose reagent was made by Hunan Sansure Biotechology Corporation, TMA system showed 20 positive samples and 11 negative samples in a total of 31 samples. So was the RT-PCR kit of the Sansure Biotechology Corporation, and the concordance rate of the two methods was 100%. Advanced quantitative study of the 20 positive samples found that the two methods had good correlation and consistency (r=0.91,P<0.01). Compared with the results of RT-PCR whose reagent was made by Shanghai Kehua Bio-engineering Corporation, TMA system had 34 positive samples and 36 negative samples, while the RT-PCR technology had 32 positive samples and 38 negative samples out of 70 samples. hTe concordance rate of the two methods was 97.1%, with no statistical difference in the positive rate of the two methods (P>0.05). Advanced quantitative study of 29 positive samples found that the two methods had good correlation and consistency (r=0.96,P<0.01). Conclusion:The stability and repeatability of TMA system are good within 6 months when stored at-20 ℃ storage temperature. Both TMA and RT-PCR HCV RNA can detect serum HCV RNA well, and the two methods have good correlation and consistency.
