Objective:To clarify the immediate administration issues faced by hospitals in China in their implementing the diagnosis-related groups(DRG) payment as a reference for the reform.Methods:By using " DRG" , " hospital" , and " administration" as search terms, the authors systematically retrieved literature data from CNKI, Wanfang Data, PubMed, Embase and Web of Science from the establishment of the database to April 30, 2022. Based on such data, administration issues pertaining to the reform process were extracted and built into a co-word matrix. The social network analysis was used to measure the network density and network centrality of these administration issues. The entropy weight-technique for order preference by similarity to ideal solution(TOPSIS) method was used to comprehensively evaluate the indicator results of network centrality indicators.Results:Of the 32 literatures included, 25 issues in hospital administration during the reform of DRG payment method were extracted. As shown in the social network analysis, the network density was 0.717, while the top issues ranking by degree centrality, betweenness centrality and closeness centrality, were inappropriate main diagnosis selection(68, 8.842, 25), imperfect DRG grouping device setting(54, 8.361, 26), imprecise recording of other disease diagnosis and surgical operations(60, 6.885, 26), and poor professional knowledge of medical record managers(54, 6.991, 25). The top four issues as shown in the entropy weight-TOPSIS analysis were inappropriate main diagnosis selection(1.000), imperfect DRG grouping device setting(0.871), imprecise recording of other disease diagnosis and surgical operations(0.803), and poor professional knowledge of medical record managers(0.787).Conclusions:Fill-out errors of medical record homepage, imperfect formulation of DRG grouping plans and poor professional knowledge of medical record manage team, rank the tope administration issues of high priority in implementing the reform of DRG payment methods. It is imperative to strengthen quality control of the medical record homepages, to scientifically formulate the DRG grouping plans, and to improve the construction of medical records professional team, in an effort to the further smooth and orderly implementation of the reform.

Objective To validate a chemical shift-encoded MRI(CSE-MRI)water-fat imaging for quantifying vertebral marrow fat content using MRS as the reference standard.Methods MRS and CSE-MRI were performed to calculate proton density fat fraction(PDFF) in 83 subjects,including 41 normal bone mass,26 osteopenia and 16 osteoporosis.Eight participants were scanned three times with repositioning to assess the repeatability of CSE-MRI PDFF measurements.Agreements of intra-observer and inter-observer were evaluated by intraclass correlation coefficient(ICC).Linear regression,Bland-Altman 95% limit of agreement and Lin's concordance correlation coefficient were calculated.Results The repeatability for CSE-MRI PDFF measurements expressed as absolute precision error was 1.45%.PDFF was 62.1%±11.1% by MRS and 60.4%±10.1% by CSE-MRI in 83 subjects.There were significant differences in PDFF among the normal bone mass,osteopenia and osteoporosis groups after adjusting for age,years since menopause and body mass index (all P<0.001).The intra-and inter-rater reliability for duplicate measurements at CSE-MRI PDFF were more than 0.993.Pearson correlation coefficient was 0.979 and Lin's concordance correlation coefficient was 0.962.All data points calculated using the Bland-Altman method were within the limits of agreement.Inverse associations were observed between BMD (r=-0.560--0.710)and CSE-MRI-based PDFF,and between BMD (r=-0.539--0.706)and MRS-based PDFF in various groups.Conclusion CSE-MRI with multiple lipids peak model and T2?-correction is equally accurate in characterizing marrow fat content as MRS.

This study aims to identify the original plants for Kui and Dongkuizi by reading and analyzing relevant historical literature.Misidentifications,misjudgments and false corrections by Japanese and Chinese experts as well as by modern and ancient scholars have been refuted and rectified based on comparing plant morphological characteristics,nomenclature basis,place of origin,growing environment,indications and therapeutic effects.The findings show that the ancient and modern records of the original plant for "Kui" as well as "Dongkuizi" from the family of Malvaceae is inaccurate.The original plant is creeping spinach (Basella alba,also known as Vine Spinach,Red Vine Spinach,Climbing Spinach) belonging to Basellaceae family.

Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.
