?AlM: To compare clinical efficacy between Ahmed glaucoma valve implantation and trabeculectomy in patients with primary open angle glaucoma ( POAG) .
?METHODS: This retrospective study included 58 eyes from 45 patients with primary open angle glaucoma. And 32 eyes underwent penetrating trabeculectomy ( group A), while 26 eyes were performed Ahmed glaucoma valve implantation ( group B) . lntraocular pressure ( lOP) , best-corrected visual acuity ( BCVA ) , visual field and post-operative complications were observed between these two groups.
?RESULTS:(1) lOP:the lOP of post-operation in group A were (13. 56±4. 91), (14. 47±4. 03), (17. 56±5. 74), (18. 25±5. 49), (18. 13±4. 24), (19. 68±4. 55) mm Hg at 2d, 1, and 2wk, 1, 3 and 6mo respectively; and that were (13.58±4. 16), (16. 00±4. 83), (18. 00±5. 05), (19. 42±5. 41), (18. 42±3. 37), (20. 00±5. 37) mm Hg in group B. There was no statistically significant difference in lOP between the two groups ( P> 0. 05 ). ( 2 ) BCVA: the number of visual acuity decreased eyes, with 6mo follow-up, was 7 (22%) in group A; and that was 5 in group B (19%). There was no statistically significant difference in vision loss postoperatively between the two groups (χ2=0. 061, P>0. 05). (3) Visual field: with 6mo follow-up, there were 13 eyes ( 41%) which had constricted visual field in group A, while those were 10 eyes (38%) in group B; the difference of visual field loss between the two groups was not statistically significant (χ2 = 0. 028, P>0. 05 ) . ( 4 ) Complications: six-month follow-up after operation, there were 4 eyes with shallow anterior chamber, 4 eyes with complicated cataract and 1 eyes with Descemet’s membrane detachment in group A, while that was 1 eyes with shallow anterior chamber and 1 eyes with complicated cataract in group B; there was statistically significant difference in the rate of complications between the two groups (χ2 = 4. 144, P<0. 05 ) . ( 5 ) Surgical success rate: six month after operation, the completed success rate was 37% (12 eyes) in group A, and that was 35% (9 eyes) in group B. The partial success rate was 19% (6 eyes) and 15% (4 eyes) in group A and group B respectively. The difference of success rates between the two groups was not statistically significant (χ2=0. 225, P>0. 05).
? CONCLUSlON: Both Ahmed glaucoma valve implantation and trabeculectomy are effective methods for the treatment of POAG. The clinical efficacy was no difference between the two methods. However, compared with trabeculectomy, Ahmed glaucoma valve implantation was safer and had fewer complications.

A secretive expression vector of Pichia pastoris system which can be used for the direct cloning of PCR products was constructed,and was verified through the expression of recombinant cellobiohydrolase II in Pichia pastoris.A randomly selected fragment was amplified with properly designed primers by PCR.The XhoI and Eam1105Ⅰ restriction sites were included in the 5'end of the fragment,and the Eam1105Ⅰ and XbaI restriction sites were included in its 3'end.The PCR amplified product was inserted into the P.pastoris expression plasmid pPICZ?A through XhoI and XbaI restriction sites and the resultant plasmid was digested with Eam1105Ⅰ,and lastly the big fragment was recovered,generating the P.pastoris expressive Tvector pPICZ?T.Then the cellobiohydrolase II of T.reesei was successfully expressed in P.pastoris with this expressive Tvector.Such results indicated that the constructed expression Tvector was convenient for PCR product cloning,and was effective for heterologous protein expression in P.pastoris.On the other hand,the application of the expression Tvector avoided the introduction of additional amino acids at the Nterminus of the expressed protein,which generally occurred when normal expression vectors were used in secretive expression system.

OBJECTIVE:To explore the optimal steaming time of Carapax trionycis during cleansing period,and to optimize and improve production technology of Carapax trionycis recorded by current Chinese Pharmacopoeia. METHODS:The mechanical processing replaced the artificial processing method in Chinese Pharmacopoeia. The content of protein and the appearance of Cara-pax trionycis were investigated after steaming for 30,60,90,120,180,240 min during cleansing period. The extract,decoction, ash content,appearance and property of Carapax trionycis decoction piece processed with vinegar were also investigated after cleansed Carapax trionycis decoction piece was processed by sand scalding and vinegar quenching method. RESULTS:The differ-ent steaming time obtained different quality of cleansed Carapax trionycis decoction piece and Carapax trionycis decoction piece pro-cessed with vinegar. Compared with decoction piece steamed for other duration,when the steaming time was 90 min,the content of protein in cleansed Carapax trionycis decoction piece was higher(31.16%),and its appearance was up to the requirement. Cara-pax trionycis decoction piece processed with vinegar had higher contents of extract and decoction(9.13%,11.39%)and lower con-tent of ash(66.29%),and its appearance was up to the requirement. CONCLUSIONS:Different steaming time have certain effect on the quality of cleansed Carapax trionycis and Carapax trionycis processed with vinegar,the optimal steaming time of Carapax tri-onycis is about 90 min during cleansing. The mechanical processing method maybe replace the artificial processing on Carapax tri-onycis for improving its production efficiency.

ObjectiveTo compare the prognosis of patiens with acute(within 72 hours) subarachnoid hemorrhage (SAH) within or without the clinical standardized pathway(CSP).Methods123 acute SAH cases were collected before CSP established meanwhile another 146 cases after CSP established from 2005 to 2009 in neurological intensive care unit of our hospital. Information such as age, gender, Hunt-Hess and CT-Fisher grade, timing and result of digital subtraction arteriography, treating time of aneurysm, and Modified Rankin Scale(MRS) at different time were recorded. Rehaemorrhagia, complications, mortality, prognosis and average stay were compared between two groups.ResultsThere was a significant difference between two groups in rehaemorrhagia, vasospasm，hydrocephaly, mortality, prognosis and average stay.ConclusionCSP is helpful to improve the prognosis of aneurysm subarachnoid hemorrhage.

Thirty SHRs were obtained randomly to hypertension, model group, captopril group and Qingre jiangya capsule group. Ten Wistar rats were used as control group. The hippocampus tissue was removed to explore the damage of spontaneously hypertensive rats (SHR) and the protective effect of Qingre jiangya capsule after continuously administered for 14 days. And then the data were processed by principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The research results revealed captopril group was significantly different from the other three groups. The classification of other three groups is also very clear after captopril group removed. This suggested that Qingre jiangya capsule could improve the overall metabolism compared with captopril. Four metabolites were identified: dimethylglycine, glycerophosphocholine, aldosterone and noradrenaline. Hypertension hippocampus damage may mainly be expressed in tyrosine metabolism, aldosterone-regulated sodium, vascular smooth muscle contraction reabsorption, and Qingre jiangya capsule could reverse the hippocampus tissue damage of SHR.
