From the view of medical professionals, this paper explored the standards of residents′ competency cultivation in Zhuhai using Delphi method. The research outcome that consisted of 53 factors and 6 dimensions was obtained after two rounds of expert consultation. There are 6 first-level indexes including professionnalism and body-mind quality, clinical practice skill, the competency of lifelong learning and self-improvement, humanistic medicine practice skill, medical knowledge, and the competency of promoting the medical system to develop. As well, there are 18 second-level indexes and 29 third-level indexes. The standards stated that the clinical prac-tice skill would not be the main part of residents′competency cultivation. Qualified residents should reach the na-tional standard of the clinical practice skill but also the other five indexes.

Objective To study the effect of three kinds of disinfection liquid,namely chlorine dioxide,silver ion and BIOCIDE,on sterilization of Legionella pneumophila.Methods The suspended quantified disinfection test was conducted by using 7 type of Legionella p neumophila,0.5 ml of bacterial suspension and 4.5 ml disinfection liquid were mixed for certain period, the normal saline was used as the control.1.0 ml of the above liquid or its dilution was incubated with BCYE for 72 h in CO_2 and 35 ℃,the colony count and sterilization rate were calculated.Results The sterilization rate of chlorine dioxide was 6.04%,7.87% and 18.18% at the sterilization time of 0.5,1 and 2.5 h respectively.The sterilization rate of silver ion was 52.61%,99.46% and 99.80% at the time of 0.5,1,1.5 and 2.0 h respectively.As for BIOCIDE,the sterilization rate was 25.28%,93.62%,96.60% and 99.81% at the time of 0.5,1,1.5 and 2 h respectively.Conclusion Compared with chlorine dioxide,silver ion and biological disinfectant has a better sterilization effect on Legionella pneumophila.

Objective To investigate efficacy of citalopram on pathological crying after cerebral infarction.Methods 106 patients with pathological crying after cerebral infarction were randomly divided into two groups,treatment group(54 cases) and control group(52 cases).Control group received conventional treatment of cerebrovascular disease.Treatment group taken citalopraml0-20mg orally one time per day for three months based on conventional treatment.The total response rate,effectual time,and Hasegawa Dementia Scale (HDS) scores were compared between two groups after treatment.Results There were significant differences in total response rates (94.4％ and 38.5％,respectively),effectual time(1.98 ± 1.24 and 78 ± 17.95,respectively) and HDS(8.43 ±2.21 and 6.24 ±2.02,respectively) between treatment group and control group (P ＜ 0.01).Conclusion The study suggests that it is effective to treat pathological crying with citalopram and its effect is quick.Citalopram can not only control patient’s pathological crying,but also improve cognitive function.

Abstract: At present, nucleic acid detection technology based on the PCR principle is commonly used to detect malaria parasites, the existing Plasmodium detection methods mainly include microscopy, antigen immunoassay, and nucleic acid detection,but due to the long detection time, high personnel and equipment requirements, and other shortcomings, its popularization, and application at the grassroots level are limited. What challenges previous Plasmodium detection methods are the lack of experienced professionals and advanced equipment at the grassroots as well as the requirement of rapid detection of large samples under extreme conditions. The isothermal amplification technology developed in recent years has potential application prospects due to its simplicity, rapidity, high sensitivity, and high specificity. This article attempts to review the principles, characteristics, and prospects of various isothermal amplification technologies, and on this basis, focuses on the introduction of recombinase polymerase amplification (RPA) and recombinase⁃aided isothermal amplification (RAA) assay technologies and proposes the use of such recombinant enzyme amplification technologies to achieve rapid and accurate diagnosis of common Plasmodium species possibility and imagination.

The chemical constituents isolated from Desmodium species (Leguminosae) included terpenoids, flavonoids, steroids, alkaloids compounds. Modem pharmacological studies have showed that the Desmodium species have antioxidant, antibacterial, anti-inflammatory, hepatoprotective, diuretic, antipyretic, analgesic and choleretic activity. This article mainly has reviewed the research advances of chemical constituents and biological activities of Desmodium species since 2003.
