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 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.

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.

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.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy combined with limited open repair of medial collateral ligament (MCL) for the treatment of multiple ligament injuries of knee joints.

METHODSFrom March 2006 and June 2012,the data of 14 patients (14 knees) with multiple injuries of ACL, PCL, and MCL were collected. There were 8 males and 6 females with an average age of (31.8 +/- 8.1) years old (ranged, 20 to 49 years old). All the patients were performed with X-ray and MRI examination, and the results showed that 10 patients had combined with injuries of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL); 4 patients had ALC,PCL and posterolateral corner (PLC) injuries. Four patients had medial meniscus injuries and 2 patients had lateral meniscus injuries. The MCL,PLC and meniscus injuries were treated with operation on the first stage, and functional exercises were performed 3 weeks after fixation. The reconstruction operation of ACL and (or) PCL was performed at the second stage under arthroscopy 3 to 6 months later when the movement range of knee joint recovered to the normal level with obvious relaxation.

RESULTSAll incisions healed by primary intention. All the patients were followed up with a mean duration of 48.9 months (ranged, 24 to 80 months). The Lysholm score was improved from preoperative 19.6 +/- 0.9 to the latest follow-up 87.1 +/- 2.8 (t=12.3, P<0.01). The International Knee Documentation Committee (IKDC) rating: 9 cases nearly recovered to normal, 5 cases were abnormal.

CONCLUSIONFor multiple ligament injuries in the knee, staged repair and reconstruction can effectively restore knee joint stability and function.
