Landing practices of national medical insurance negotiated drugs in tertiary medical institutions of Zhejiang province / 中国药房

OBJECTIVE To provide reference for the subsequent landing of national medical insurance negotiated drugs （referred to as “national negotiated drugs”） at the provincial level. METHODS By reviewing the data publicly released by the official websites of National Healthcare Security Administration and the Healthcare Security Administration of Zhejiang Province， combined with policy documents， the descriptive analysis was conducted on the number of tertiary medical institutions， the actual allocation of national negotiated drugs， the availability rate of national negotiated drugs， the allocation rate of national negotiated drug varieties， and the allocation rate of medical institutions of various cities in Zhejiang province. The Spearman rank correlation test was used to analyze the correlation between the number of types of national negotiated drugs equipped in tertiary medical institutions in Zhejiang province and the per capita disposable income， the number of tertiary medical institutions equipped with national negotiated drugs， and the implementation time of disease diagnosis-related grouping （DRG） of various cities in Zhejiang province. RESULTS As of the first quarter of 2022， 135 tertiary medical institutions in Zhejiang province were equipped with a total of 261 types of national negotiated drugs， accounting for 94.91% of the 2021 edition of the National Negotiated Drugs Catalogue （275 types）. The allocation rates of Goserelin acetate sustained-release implant， Sacubitril valsartan sodium tablets， Alteplase for injection and other varieties were at high level， and the types of national negotiated drugs equipped were highly coincident with the top 10 causes of death with disease of urban and rural residents in Zhejiang province. The tertiary medical institutions in Hangzhou had the most types of national negotiated drugs， with 230 types， while Quzhou had the lowest， with only 34 types； allocation rate of national negotiated drugs in medical institutions of Zhoushan was the highest （100%）， while that of Lishui was the lowest （57.14%）. The types of national negotiated drugs equipped were positively correlated with per capita disposable income in various cities and the number of tertiary medical institutions equipped with national negotiated drugs （P＜0.01）， and there was no significant correlation with the length of implementation of DRG （P＞0.05）. CONCLUSIONS mail：lanyao@mails.tjmu.edu.cn The landing of national negotiated drugs in Zhejiang province is generally good， with a high rate of equipping tertiary medical institutions with national negotiated drugs and a high rate of equipping drug varieties. Therefore， it is recommended that the provincial implementation of national negotiated drugs should be multi-faceted， and policy-making departments should adopt a dual-channel of “unbundling” and “driving” to smooth the drug chain into hospitals. The health insurance sector should improve the “dual channel” management mechanism to share the pressure on hospitals to use drugs. At the same time， it should also improve the multi-level medical security system and raise the level of reimbursement of medical insurance for national negotiated drugs.

Effect analysis of three-dimensional and two-dimensional imaging systems in laparoscopic radical resection of rectal cancer / 中华消化外科杂志

Objective To compare the clinical effect of three-dimensional(3D)and two-dimensional(2D)imaging systems in laparoscopic radical resection of rectal cancer.Methods The retrospective cohort study was adopted.The clinical data of the 97 patients who underwent laparoscopic radical resection of rectal cancer at the Xinmin Branch of the China-Japan Union Hospital of Jilin University between May 2012 and December 2014 were collected.Of 97 patients,47 undergoing 3D laparoscopic radical resection of rectal cancer were allocated into the 3D group and 50 undergoing 2D laparoscopic radical resection of rectal cancer were allocated into the 2D group.The operation followed strictly tumor-free and total mesorectal excision principles.Observation indicators included:(1)surgical situations:operation time,time of deep lymph nodes dissected,volume of intraoperative blood loss,bleeding volume of obturator lymph nodes dissected,number of lymph nodes dissected,postoperative complications and duration of hospital stay.(2)Follow-up situations:follow-up using outpatient examination and telephone interview was performed to detect the survival of patients and tumor recurrence and metastasis up to December 2015.Measurement data with normal distribution were presented as-x±s and comparison between groups was analyzed using the t test.Count data were analyzed using the chi-square test.Results(1)Surgical situations:all the patients underwent successful laparoscopic radical resection of rectal cancer,without conversion to open surgery.Operation time,time of deep lymph nodes dissected,volume of intraoperative blood loss,bleeding volume of obturator lymph nodes dissected,number of lymph nodes dissected and duration of postoperative hospital stay were(134.6±18.5)minutes,(21.2±2.7)minutes,(65±20)mL,(16±3)mL,23.6±3.5,(8.2±2.3)days in the 3D group and(157.4±17.8)minutes,(25.2±2.5)minutes,(89±27)mL,(23±5)mL,20.5±2.8,(9.4±2.1)days in the 2D group,respectively,with statistically significant differencesbetween the 2 groups(t=2.999,3.739,2.327,4.221,2.337,1.274,P＜0.05).The postoperative complications were detected in 7 patients in the 3D group and 9 patients in the 2D group,with no statisfically significant difference between the 2 groups(x2=0.170,P＞0.05).(2)Follow-up situations:75 of 97 patients were followed up for 12-36 months with a median time of 24 months,including 35 in the 3D group and 40 in the 2D group,and they were tumor-free survival.Conclusion Compared with 2D laparoscopic radical resection of rectal cancer,3D laparoscopic radical resection of rectal cancer can shorten the operation time and reduce tissue damage and intraoperative blood loss,and it is beneficial to deep lymph node dissection.

XP-16, a new xanthono-pyridine derivative, induces apoptosis in human lung carcinoma A549 cells / 中国药理学通报

Aim To investigate the anticancer effect of a new xanthono-pyridine derivative N, N '-( 7-oxo-7H-chromeno[3,2-h] quinoline-5,9-diyl)-bis(2-( pyrroli-din-1-yl)acetamide) (XP-16) on human lung carcino-ma cell line A549 and the potential mechanism. Meth-ods Antiproliferative effect of XP-16 on A549 cells was evaluated by MTT assay, morphological examina-tion and colonial assay. Apoptosis detection was car-ried out using Hoechst 33258 and PI double-dyeing method. Intracellular Ca2+ concentration ( [ Ca2+] i ) and mitochondria membrane potential were detected by fluorospectrophotometer. A549 cells treated with XP-16 were collected for Bad and metallothionein 1 A ( MT-1 A ) transcript analysis by real-time reverse tran-scriptase-polymerase chain reaction ( qRT-PCR) . Re-sults XP-16 inhibited A549 cell proliferation in dose-and time-dependent manner. Typical apoptotic mor- phology such as chromatin aggregation and nuclear fragmentation was observed in A549 cells treated with XP-16 for 24 h, and the apoptosis was showed in a dose-dependent manner. After treated with XP-16, [ Ca2+] i and mitochondria membrane potential of A549 cells were decreased, and relative mRNA level of Bad and MT-1A was up-regulated. Conclusions XP-16 has anticancer effect on A549 cells through apoptosis, which might be associated with decreasing intracellular Ca2+ concentration and mitochondria membrane poten-tial. Up-regulation of MT-1A expression might be the result of decreased [ Ca2+] i .
