Study on the Case of Improving the Utilization Ratio of Literature Resources in Medical College Libraries / 医学信息学杂志

The paper investigates and analyzes the utilization of literature resources by readers in medical college libraries based on questionnaire survey to find out the problems and causes of literature resource construction work in medical college libraries,and puts forward a series of measures to improve and promote the utilization ratio of literature resources in medical college libraries and give full play to the functions of medical college libraries.

Study on leaf transpiration and stomatal structure of medicinal plant Tetrastigma hemsleyanum / 中草药

Objective: Taking annual Tetrastigma hemsleyanum (Tetrastigma Radix) from three habitats, Taizhou, Minhou, and Shunchang, as materials to study the effects of different light intensity stress on the stomatal shape and leaf transpiration. Methods: The stomata, leaf transpiration rate, net photosynthetic rate, and stomal structure of T. hemsleyanum were observed using a scanning [0-2000 μmol/(m2·s)] to explore the optimal light intensity. Results: The stomata with surround and parallel distribution types were only distributed in the lower epidermis in the leaves of T. hemsleyanum; The transpiration rate, stomatal conductance, and net photosynthetic rate of T. hemsleyanum from the two habitat regions (Minhou and Taizhou) by rising after falling with the 30℃ stress, which suggested the stress could make the light intensity heavier. At the same time, the transpiration rate, stomatal conductance, and net photosynthetic rate of T. hemsleyanum from the habitat region Shunchang were rising. The stomatal type of leaves was 600 μmol/(m2·s) in Minhou, and 1900 μmol/(m2·s) in Shunchang, when the water utilization ratio of T. hemsleyanum leaves from the three habitats was higher. Conclusion: Different habitats and light intensity are the important factors of leaves transpiration in natural world, which is more beneficial to the growth of the root crops and suitable for the accumulation of flavonoids in plants.

Use of electronic resources in college and university library at present and measures for its improvement / 中华医学图书情报杂志

The measures taken by Library of Southern Medical University to improve the use of its electronic re-sources were described according to the major problems in use of electronic resources in domestic college and uni-versity libraries from resources assessment, resources integration and revealing, resources popularization and librarians support, with certain rational suggestions proposed for increasing the utilization ratio of electronic resources, inclu-ding popularization of resources, training of user information literacy, and improvement of users ability.

Research on the management of large-scale instruments in medical schools / 中国医学装备

Objective: To analyze the present situation of the management of large-scale instruments in a medical school and give some reasonable suggestions. Methods: Through the research on the use of 85 large-scale instruments in our university, we tried to find out the methods of improving the utilization ratio of large-scale instruments. Results:There are many reasons of the poor management and low utilization rate of large-scale instruments in medical schools. Conclusion: Taking some measures could effectively improve the utilization rate of large-scale instruments in medical schools, such as simplifying the working procedure, solving the operating and repair expenses, strictly controlling argumentation, drawing up scientific evaluation and incentive measures and so on.

Multicenter ICU Surveillance Study for Nosocomial Infection in Korea / 병원감염관리

Purpose: The purpose of this study is to determine the risk adjusted nosocomial infection (NI) rate and distribution of Nls and their causative pathogens in adult lCU. Methods: Prospective surveillance was performed at 12 lCU's of 5 acute care hospitals in Seoul and Kyonggi Do during a 3-months period from May to July 2002. The case finding was done by direct reviews of medical charts regularly for all patients by ICPs using CDC definitions. Results: Total NI rate was 10.18/1,000 patient-days in Medical-surgical ICU (MSICU) and 12.35/1,000 patient-days in Neurosurgucal ICU(NCI). Risk adjusted infection rate was 3.44 in indwelling catheter associated UTI 2.12 in central line associated BSI. 3.51/1,000 device-days in ventilator associated pneumonia in MSICU. There were 3.72, 2.26, 6.06/1,000 device-days in NCU. The infection rate by leu type showed no significant difference. The distribution of Nls were PNEU (28.99%). UTI (28.99%), BSI (18,84%), SSI(4.35%) in MSICU, and UTI(48.0%), PNEU(24.0%), BSI (14.0%), SSI(6.I) in NCU. The most commonly isolated organisms were Candida spp (38.6%), Enterococcus spp. (13.4%) in UTI, Staphylococcus aureus(36.2%), p. aeruginosa(18.8%) in PNEU and Coagulase negative staphylococcus(44.1%). S. aureus (14.7%) in BSL, S. aureus (19.8%) was the most common organism from overall nosocomial infections in the ICU, and 96.3% of S. aureus were MRSA. Conclusion: Distribution of site-specific nosocomial infection and isolated organisms were similar to the results of KOSNIC (Korea society for nosocomial infection control) surveillance in 1996. However, the total infection rate and a risk adjusted infection rate at MSJCU is lower than 1996's. This decrease is considered to be a result of efforts to prevention and control nosocomial infections.
