Objective: To explore the costs and other information of two different treatment plans for pediatric acute promyelocytic leukemia (APL): one is the traditional intravenous drip arsenic (arsenic trioxide) combined with chemotherapy treatment, and the other is a medication family treatment program based on oral arsenic (Realgar-Indigo naturalis formula), in order to provide a reference for the promotion of pediatric APL family treatment mode and the formulation of medical insurance policies. Methods: The medical record homepage data and drug using of pediatric APL from 2010 to 2018 in Institute of Hematology & Blood Diseases Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College were retrospectively analyzed, and the newly diagnosed pediatric patients (≤14 years old) with APL were included. The hospitalization expenses and hospitalization time of two treatment options were compared. One treatment option was Chinese children APL treatment plan 2010 (CCAPL 2010), which was based on intravenous drip arsenic trioxide. The other was Chinese Children Cancer Group APL treatment plan 2017 (CCCG-APL 2017), which was based on oral Realgar-Indigo naturalis formula. Results: A total of 79 pediatric APL patients were included and grouped according to the treatment plans, 56 patients were treated with CCAPL 2010 plan, and 23 patients were treated with CCCG-APL 2017 plan. The median costs of one single pediatric APL patient in CCAPL 2010 plan was 167 700 yuan (95 800-386 600 yuan), and the median hospital stay time of one single pediatric APL patient was 102 days (14-157 days). The median costs of one single pediatric APL patient in CCCG-APL 2017 plan group was 118 700 yuan(50 800-270 600 yuan), and the median hospital stay time of one single pediatric APL patient was 37 days(5-96 days). The costs and hospital stay time of one single pediatric APL patient with CCCG-APL 2017 plan were remarkably less than those of one single pediatric APL patient with CCAPL 2010 plan (U = 178, P < 0.01; U = 66, P < 0.01). Conclusions The CCCG-APL 2017 plan simplifies the treatment plan compared with the CCAPL 2010 plan and significantly reduces the patient's medical expenses and shortens the hospitalization days. The CCCG-APL 2017 plan is suitable for family therapy and has good social and economic benefits, which is worthy of clinical promotion.

The reuse of high-cost single-use medical devices (SUD) is permitted in many countries, such as the United States, Germany and the United Kingdom, but strict regulatory requirements must be met. In addition to regulatory policies and regulations, such as market access mode and special requirements on Good Manufacture Practice (GMP), there are strict technical requirements on the potential risk control and quality assurance system. Therefore, effective risk assessment and risk control technology are the keys to ensure effective quality control and safe use of SUDs. In this article, based on analyzing the technological requirements of the national regulatory on SUDs in the United States, Germany and Britain, and combined with the review from latest relevant literature, to discuss the strategies of how to carry out scientific risk assessment. Some risk control technologies on the reuse of SUDs are introduced, which will provide support for the further study on risk control strategies and regulatory decisions for the reuse of SUDs in China.

Purpose To evaluate the value ofintravoxel incoherent motion (IVIM) imaging in diagnosis of liver fibrosis staging in rats.Materials and Methods Rabbit models of liver fibrosis at different stages were established.All rabbits were divided into four groups based on the pathological results of fibrosis grading as S1-S4.The 1VIM imagings with 8 b-values (0,50,100,200,300,800,1000,1200 s/mm2) were performed.The diffusion coefficient (D),perfusion-related coefficient (D*),and perfusion fraction (f) were calculated and compared between control (only injection of saline) and S 1 group,S2 and S3 group.Results The D value was significantly lower in S1 group compared with control group (P＜0.05),but the D* and f values showed no significant difference between the two groups (both P＞0.05).With the progression of liver fibrosis,the D,D* and f value decreased gradually;the D* value showed significant difference between S2 and S3 group (P＜0.05),but the D and f values showed no significant differences between the two groups (both P＞0.05).Conclusion The D value is useful for differentiation of normal liver and hepatic fibrosis of S1 stage,while the D* is valuable for differentiation of hepatic fibrosis of S2 and S3 stage.However,the f value neither could detect early fibrosis,nor could differentiate hepatic fibrosis staging.IVIM imaging provides a noninvasive method for early and accurate staging of liver fibrosis,which may be of great help in clinical diagnosis and treatment.
