Construction of security system plays an important role in the management of archive in research institute.With years' practice and exploration,we summarize our experiences in building up the security system of our institute here.This article involves two aspects of archive work,one is the conscious awareness of archive security and security system building.Suggestion on security cultural construction,digital file safety and data backup are also given.

Multiagent chemotherapy has significantly improved survival for childhood ALL.However,the relapse rate with current therapies remains at 20% to 30%.Numerous studies have proved that the minimal residual disease(MRD)is associated with relapse rate.The major methods for the detection of MRD include polymerase chain reaction(PCR)and flow cytometry(FCM).The measurement of MRD in childhood acute lymphoblastic leukemia offers the promise of individualized,risk-stratified treatment and the prediction for post-transplant outcome.

Case based study emphasizes on the training of students' practical clinical ability. With the development of computer technology, picture archiving and communication system was widely applied, providing bases for case based study. According to the characteristics of radiology, appli-cation of case based study in medical imaging practice teaching was believed to stimulate students' learning interest, improve their analytical ability and thinking capacity, make them combine theory with practice better and develop their clinical thinking ability.

Objective To investigate the effects of fruit potassium supplement on hypokalemia at in the perioperative period of percutanous coronary intervention(PCI)? Methods Ninety cronary herat disease patients with hypokalemia undergoing PCI during July to December 2011 involved the study? Since admission,the patients were administered with oranges and bananas each 500 g daily until the third day after PCI,on the basis of oral administration of potassium? Serum potassium was assessed in all patients at time points of the day at PCI,the first day and third day after PCI? Results The time range for the patients to take potassium supplement by eating fruits was 12-45 hours,averaged(28?84 ± 11?70)hours? The serum potassium levels on days 1 and 3 were significantly higher than that on the day for the admission(P < 0?05 for both)and even maintained at the normal level? Conclusion The oral complement of potassium by eating bananas and oranges can help patients to correct and prevent hypokalemia during the perioperative period of PCI?

[Objective] To sum up researches on components, pharmacological actions and toxicity of Polygonum multiflorum Thunb(Heshouwu). [Method] The research reference about Heshouwu in CNKI, VIP and PUBMAD database is col ected and calssified to three aspects on components, pharmacological actions and toxicity.[Result]①On components:Heshouwu contains stilbene, lecithin, anthraquinone, flavonoids, tannin and trace elements. The stilbene and anthraquinone are the mainly active components. Producing area, growth years, harvest time and processing methods are factors affecting the content of the components such as TSG in Heshouwu; Macroporous adsorption resin is the main separation method for preconcentration of TSG and anthraquinone constituents; ② On pharmacological actions and toxicity: Heshouwu has effects of hypolipidemic and liver protection, antioxidative, anti-osteoporosi, hpyerglycemic, antidepressive and antibiosis, the hypolipidemic and liver protection are the main effects which have been studied more. A reversible liver injury which displays as abnormal liver function parameter and bile metabolic disorder would be induced if the Heshouwu is administrated with a large dosage for long term. The possible components which would induce the toxicity in Heshouwu are tannin and anthraquinone, and the anthraquinone is the component with double effects of toxicity and therapy which should be considered in clinical application. [Conclusion]Reducing lipid and protecting liver is the main pharmaceutical function of the herb. As a commonly used Chinese herb for liver protection, the studies on alcoholic hepatic injury protection of Heshouwu may be a point for the researchers to focus on. The comparison studies on hypolipidemic and liver protection between Hesouwu and its processing products, and the correlations between components and pharmacological actions are worth study further.

In order to safeguard the legitimate rights and interests of the subjects and the interests of the whole society , a relaxed and harmonious environment was created to ensure the normal medical research , clini-cal research trials which fit in trial of ethical review. The protocol assessment form and ICF assessment form to review are two cornerstones of protecting subjects. A good ICF assessment form is a necessary means to help improve the quality of the Ethics Committee for review .

Biomedical research involving human subjects must be approved by the ethical review. The method of improving ethics committee members of the examination quality is not only by the members themselves , but also a good plan of the work table, which is also a necessary means to improve the quality of the ethical review.

Giant cell tumor (GCT) is rare and it mainly occurred in male patients. A man of 65 years-old with progressive dyspnea has a 4 cm x 4 cm x 3 cm tumor mass under the right vocal fold originated from right-thyroid cartilage and the parapharyngeal space. The right false vocal was involved in the computed tomography (CT) imaging and laryngoscope. Microscopically, the tumors had an expansile, infiltrative growth and consisted of numerous multinucleated osteoclast-like giant cells within a cellular stroma composed of plump and oval mononuclear cells. The patient underwent partial laryngectomy and has been followed up for 6 months without recurrence or metastasis.

Objective]To observe the clinical effect of Yinlai Decoction Addition and Subtraction on treating Pediatric Cold about lung-stomach heat retention syndrome.[Method]This study adopted the research design method of case series reports, continuously included 40 Pediatric Cold children with lung-stomach heat retention syndrome treated by Yinlai Decoction Addition and Subtraction from November 2011 to December 2012. Through clinical visiting, we could assess the treatment outcome of this time on the basis of evaluation standard. [Results]33 patients were cured, 5 patients turned better and 5 patients had no effect, the total effective rate was 95.00%. [Conclusion]Yinlai Decoction had clearing and dispersing function, it could treat lung and stomach simultaneously, therefore, it had obvious efficacy in Pediatric Cold about lung-stomach heat retention syndrome.
