Objective To explore the clinical effects of phacoemulsification with intraocular lens implantation for cataract patients who have had glaucoma and have undergone trabeculectomy before.Methods Phacoemulsification with intraocular lens implantation was performed on 33 patients(38 eyes)with cataract after trabeculectomy.The postoperative visual acuity,intraocular pressure(IOP),filtering bleb,corneal endothelium and complications were observed.Results No posterior capsular rupture occurred and all the lenses were inserted into the capsular bags.Follow up for 3 months at least.The correct visual acuities were≥4.7 in 30 cases(78.9%),≥5.0 in 6 cases(15.8%).Postoperatively,the IOP of all eyes was below 20mmHg and there was no change in the filtering bleb.The loss rate of the corneal endothelial cells was 15.07%after the operation.The density of the postoperative corneal endothelial cells was statistically significant different from those of the preoperative(t=4.582,P＜0.01).The complications occurred more than that of regular phaeoemulsification.Conclusions Phacoemulsification is convenient and effective in patients with cataract after trabeculectomy.The incision should be made without damaging the filtering bleb.The surgery requires skillfully and actively enlarging the small pupils and protecting the corneal endothelium.

Objective To investigate the clinical effects of phacoemulsification with foldable posterior cham-ber intraocular lens implantation in the treatment of primary angle closure glaucoma with cataract .Methods 82 patients(82 eyes) with primary angle closure glaucoma with cataract were selected as the research objects ,and taken the treatment of combination of phacoemulsification and posterior chamber foldable intraocular lens implanta -tion.c The vision,intraocular pressure ,anterior chamber depth and angle opening changes before and after 6 months of operation were ompared ,and the postoperative complications were observed .Results 54 eyes achieved best corrected visual acuity of more than 0.5,12 eyes achieved best corrected visual acuity of 0.4,6 eyes achieved best corrected visual acuity among 0.1 to 0.3 and 6 eyes achieved best corrected visual acuity of less than 0.1.The difference between postoperative best corrected visual acuity and that before operation had significant statistical differences (χ2 =43.244,P<0.01).After having the operation ,the intraocular pressure of acute closed angle glaucoma pre clinic , onset period and chronic angle closure glaucoma had significantly improved compared to pre -operation ( t=7.955, 4.741,5.638,all P<0.01).The chamber depth of the three groups had also improved substantially compared to that of pre-operation(t=13.080,11.890,16.124,all P<0.01).The degree of angle opening of acute closed angle glau-coma and chronic angle closure glaucoma were better than that of pre-operation,and postoperatively ,the degree of an-gle opening of the former turned out to be wider than that of the latter (χ2 =9.246,P<0.05).There were no postop-erative intraocular lens clamping,corneal decomposition,severe complication of retinal detachment and macular cys-toids edema .Conclusion The phacoemulsification combined with intraocular lens implantation for the treatment of primary angle closure glaucoma with cataract can effectively improve visual acuity ,control intraocular pressure ,deepen the anterior chamber ,open angle ,and the adverse reactions occurred less ,which is worthy of clinical application .

ObjectiveToestablishanionchromatography(IC)methodfordetectionofammoniainthe environmental air of laboratory animal facilities .Methods Dilute sulfuric acid was used as the absorption liquid to collect ammonia in the air.Ammonia was converted into ammonium ion in the absorption solution .With methylene sulfonic acid as the pouring liquid , the content of ammonium ion in the absorption solution was detected , and the concentration of ammonia in the air was calculated.Results The ammonium ion showed good linearity in the range of 0 to 1μg/mL (r=0.9994), and high precision ( RSD<6.38%) .The lowest detected concentration was 0.012 mg/m3 , and the average recovery was 98.8%.Conclusions This is a simple method , easy to operate , not interfered by other ions , and can be used to detect the ammonia in the environmental air of laboratory animal facilities .

The application of genetic engineering technology in modern agriculture shows its outstanding role in dealing with food shortage. Traditional medicinal plant cultivation and collection have also faced with challenges, such as lack of resources, deterioration of environment, germplasm of recession and a series of problems. Genetic engineering can be used to improve the disease resistance, insect resistance, herbicides resistant ability of medicinal plant, also can improve the medicinal plant yield and increase the content of active substances in medicinal plants. Thus, the potent biotechnology can play an important role in protection and large area planting of medicinal plants. In the development of medicinal plant genetic engineering, the safety of transgenic medicinal plants should also be paid attention to. A set of scientific safety evaluation and judgment standard which is suitable for transgenic medicinal plants should be established based on the recognition of the particularity of medicinal plants.

Bioceramics, because of their advantages such as biocompatibility and osteoconduction, have been widely used for bone repairing and bone substitute as bone tissue engineering materials. This study primarily compares the characteristics and the application range of some kinds of bioactive ceramics and biodegradable ceramics, and introduces their latest development in degradability and strength et al. Among these materials, calcium polyphosphate is a new material as bone tissue engineering scaffold. With a controllable degradation rate and the required strength, it has been paid much attention.

Objective:The causes, management, and prevention of complications in laparoscopic gyneco-logic surgery were investigated. Methods:A retrospective analysis was done based on clinical data of 8279 cases of laparoscopic gynecologic surgery from January 1996 to December 2008 in this hospital. Results:The complication rate was 0.88% (73/8279). These included five cases intraperitoneal bleeding, five cases injury of ureter, 20 cases abdominal vessel damage, 10 cases vulva emphysema, 25 cases wound healing delay and each one case respectively for stomach injury, bladder injury, secondary abdominal cavity preg-nancy,infection and incision hernia. The occurrence rates of complications between hysteroscopy combined with laparoscopic surgery and pure adnexal surgery were no difference( P >0.05). Compared to adnexal op-erations, there was a significantly higher complication rate in myomectomy and laparoscopic assistant vaginal hysterectomy (P < 0.01 ). Conclusions:Complications of laparoscopic gynecologic surgery are correlated with the difficulty of operation and the skillfulness of operators. In order to reduce complications, careful oper-ation and avoiding over self -confidence are essential.
