ABSTRACT
Objective To implement the disease control and prevention information system digital certification in Tianjin,to achieve full coverage of network direct reporting unit digital certification in the city and to improve the ability to control security risks like information leakage.Methods CA certificate management was implemented with hierarchical framework and electronic authentication cloud platform of national disease control and prevention information system in China.The life-cycle certificate management was realized for certificate update,unlocking,reissuance and withdrawal.A silent server was deployed in Tianjin Centers for Disease Control and Prevention for annual update of digital certificate.Results The digital certificate was issued to the user of Tianjin disease control and prevention information system,the integration was realized with national cloud authentication platform,and digital certificate authentication was implemented for user access.The risks for information leakage were eliminated during network reporting of disease control and prevention information.Conclusion All the authorized users of China's disease control and prevention information system in Tianjin area gain the authentication for access based on digital certificate,and the safety system is improved greatly.
ABSTRACT
? AlM: To study the application value of phacoemulsification in clinical treatment of angle-closure glaucoma.?METHODS:A total of 60 cases ( 82 eyes ) , the best corrected visual acuity, anterior chamber depth, intraocular pressure, width of chamber angle and adverse reaction of patients were researched and analysed before and after treatment.?RESULTS:ln this group, 60 cases (82 eyes) compared with that before treatment, the best corrected visual acuity in patients after treatment significantly improved, with significant difference between the two groups ( P<0. 05 ); anterior chamber depth of patients before treatment were 2. 0±0. 3mm, anterior chamber depth after treatment was 4. 4 ± 1. 0mm, treatment of patients with anterior chamber depth comparison significantly improved after treatment, with statistically significant difference between the two groups ( P<0. 05 ); lOP in patients with postoperative effective control over an extended period, the difference before treatment was statistically significant ( P<0. 05 ); the width of chamber angle after treatment compared with before treatment significantly increased, with statistically significant difference between the two groups ( P < 0. 05 ); after treatment by the emergence of 5 corneal edema, 3 mydriasis, an iris atrophy, no one cases of retinal detachment.?CONCLUSlON: Phacoemulsificationin the treatment of angle - closure glaucoma has a high value, can be effectively corrected visual acuity, improve patient anterior chamber angle width and depth, a small incidence of adverse reactions.
