Objective:To assess the indication,preliminary efficacy and complication of endovcnous laser treatment (EVLT) for varicose veins.Methods:A study was carried out on 63 limbs of 38 patients with varicose veins.59 of 63 limbs were treated by EVLT and 4 of 63 limbs were treated by both EVLT and surgical ligation.Patients were evaluated at 3,7 days and 1,3,9 months to determine efficacy and complications.Results:62 of 63 greater saphenous veins were closed after treatment,and the remaining one was closed after repeat treatment.There were no significant complications and no recurrence at 2～9 months after treatment.Conclusion:Endovenous laser treatment of varicose veins of lower extremities is a safe,effective and feasible method.It can be applied to the patient of clinical stages C_2～C_6 according to CEAP classification and can be cooperated with surgical ligation without serious complications.

OBJECTIVE To observe the clinical therapeutic effect of levofloxacin combined with cefoperazone-sulbactam on pulmonary infection caused by multidrug-resistant(MDR) bacillus infection.METHODS Eighty five patients with pulmonary infection caused by MDR bacillus infection were randomly divided into treatment group and control group,combined levofloxacin and cefoperazone-sulbactam were used in 45 patients of treatment group,ceftriaxone sodium was used in 40 patients of control group,their therapeutic effect was observed 7 days later.RESULTS Thirty four patients of treatment group were cured,7 patients with excellence,3 patients with improvement and only 1 patient was invalid.The total effective rate was 91%.Clinical manifestation such as cough,expectoration,and dyspnea had obviously improved.Sputum culture darkening rate was high.CONCLUSIONS Combined therapy of levofloxacin and cefoperazone-sulbactam has definite therapeutic effect on pulmonary infection caused by MDR bacillus infection.

Objective:This paper makes analysis of problems of emergency equipment existing in clinical application and their causes and puts forward corresponding measure. Methods:Analysis of emergency medical equipment characteristic and the difference between conventional equipment. Find the first aid equipment management problems and reasons existing in the use, and risk assessment. Results:Hospital first aid equipment has the characteristics of more free time, emergency and risks, widely distributed in each department. By the personnel management, periodic inspection, cleaning and disinfection. Risk assessment shall be conducted by experts, the risk value high priority arrangement first aid equipment maintenance, to expect to minimize risk. Conclusion:First aid equipment management is a systematic and important work, to need department, maintenance personnel, equipment manufacturers and so on various aspects to cooperate with each other, to ensure the normal use of equipment.

To find a good model for experimental teaching in medical college we established five experimental teaching centers five years ago,and up to now the experimental teaching centers are operated well,and the teaching environment has been improved,the teaching cost has been reduced,and teachers'research abilities enhanced.What's more,the students'hands-on abilities are well developed,and more attention has been paid to experimental teaching.

Objective: To improve the whole-process management of medical devices in purchase, use and maintenance. Methods: In this paper, we clarify the purchase, use and maintenance requirements of large-scaled medical devices including justification, invitation organization, comprehensive estimation, contract signing protocol, advantage analysis, rational control of availability, efficacy measurement and detection, management at different levels, high-efficacy check-up and scrap procedure to adapt the new challenges during the introduction of more and more advanced, complex and high-tech medical devices. Results:The results being analyzed could be used as important evidence for future purchasing of medical equipment, which was important for scientific and reasonable purchasing and utilizing of medical equipment. Conclusion: Strengthen the management to adapt the new challenges during the introduction of more and more advanced, complex and high-tech medical devices.

Objective: To establish the Perfect Systematization and Informatization for the Management of Medical Equipment Archive, so as to ensure the integrity and traceability of each data. Methods: Analysis on Present Situation and the Problems of Medical Equipment Management, Establish Medical Equipment archive Management System from purchasing of medical equipment, Measurement Controls, the Maintenance to Scrap processing the whole-process of medical devices. Results: In this paper, we discussed all kinds of information and archives network information management in the whole-process of medical devices. To clarify the plan, argument, purchase, installation, acceptance, use, quality control, maintenance, transfers and scrap processing, management at different levels. To establish a complete electronic file system is the main direction of medical equipment information management in the future. Conclusion: Realization of the functions on medical equipment archives network information and dynamic management, that can offer necessary for safe treatment,to can also reduce the operation cost of the equipment.

AIM: To explore the main risk factors related to the incidence of endophthalmitis in patients after cataract surgery in China and to provide evidence for prevention.METHODS: The results of 5 studies on the main risk factors of endophthalmitis in patients after cataract surgery were analyzed by Meta-analysis method.
RESULTS: The pooled odds ratio values and 95% CI of age(≥70), diabetes, vitreous overflow, operative time ( ≥ 10min ), common operating room and control of using time of topical anesthetic were 1. 81(95% CI: 1. 43-1. 69),3. 66 (95% CI: 1. 64 - 8. 16),2. 21 (95% CI: 1. 46 -3. 32),3. 54 (95% CI: 2. 47 - 5. 06),2. 77 (95% CI: 2. 07 -3. 72),2. 09(95% CI: 1. 53-2. 86).
CONCLUSION: The main risk factors of endophthalmitis were the age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic.

Dry age-related macular degeneration(AMD)is a prevalent form of irreversible blindness worldwide in the elderly population with an increasing incidence in China.It is found that some dry AMD will develop to wet AMD and therefore damage visual function.Pathogenesis of AMD is below understand now,but it is thought to be related to the light-induced ocular damage,oxidative stress response,extracellular disposition and immunology.Up to now,effective and safe prevention and treatment methods of AMD are still studying,especially wet AMD,but the concern on dry AMD is not enough.Some basic and clinical pharmaceutics researches on AMD include antioxidants,anti-extracellular disposition drugs and anti-inflammatory agents.With the rise of aging population,we should pay special attention to the research on pathogenesis,diagnosis and treatment of dry AMD.
