Objective To explore the impacts of 24-hour medical records archiving on the DRGs grouping ratio and payment.Methods Retrospective survey was made in a tertiary hospital in Beijing during its pilot from November 18,2011 to May 31,2012.The study covered such categories as the 24-hour medical records archiving ratio,48-hour medical records archiving ratio,DRG grouping ratio and payment for discharged patients prior to and after the practice of such archiving requirement.The data were subject to a multilinear regression analysis.Results The practice of 24-hour archiving,since in place,has significantly raised the 24-hour ratio,48-hour ratio,DRG grouping ratio and payment ratio,with the differences statistically significant (averaging P<0.0001).DRGs payment amount is positively correlated to the number of DRGs grouping (regression coefficient 0.75284,P<0.0001).DRGs grouping amount is positively correlated to the number of 24-hour medical records archiving (regression coefficient 0.44233,P<0.0001).Conclusion The 24-hour archiving practice has significantly raised DRGs grouping and payment ratio,making it one of requisites for hospitals to successfully carry out DRGs payment system.

Objective:To evaluate the effects of quality improvement (QI) program on the incidence of bronchopulmonary dysplasia (BPD) in very preterm infants (VPIs) [gestational age (GA)<32 weeks].Methods:From July to December 2017,VPIs admitted to the Department of Neonatology of Yancheng Maternity and Child Health Care Hospital were retrospectively enrolled and were assigned into pre-quality improvement program group (Pre-QI group).From July to December 2018, VPIs were assigned into post-quality improvement program group (Post-QI group). QI program included delayed umbilical cord clamping (DCC), early postnatal nasal continuous positive airway pressure ventilation (nCPAP) and minimally invasive pulmonary surfactant therapy (MIST). The clinical data and prognostic indicators of the two groups of VPIs and their mothers were compared. Independent sample t-test or continuity-adjusted Chi-square test (or Fisher's exact test) and Logistic regression were used for statistical analysis. Results:A total of 204 VPIs were enrolled, including 96 cases in Pre-QI group and 108 cases in Post-QI group. 1 min Apgar score and hematocrit on admission to the neonatal intensive care unit (NICU) in the Post-QI group were significantly higher than the Pre-QI group( P<0.05). The incidence of delivery room resuscitation, endotracheal intubation at birth and endotracheal intubation in NICU in the Post-QI group were significantly lower than the Pre-QI group( P<0.05). The application of pulmonary surfactant and mechanical ventilation, the incidence of neonatal respiratory distress syndrome and BPD in the Post-QI group were lower than the Pre-QI group ( P<0.05). After adjusting for confounding factors, Logistic regression analysis showed that DCC ( aOR=0.261,95% CI 0.091~0.718, P=0.023), nCPAP ( aOR=0.284,95% CI 0.123~0.667, P=0.015), MIST ( aOR=0.276,95% CI 0.114~0.627, P=0.011) were protective factors of BPD, and MV ( aOR=2.023,95% CI 1.048~3.918, P=0.036) was risk factor of BPD. Conclusions:The QI program consisting of DCC, early nCPAP and MIST for VPIs can reduce the incidence of BPD.

Objective:To retrospectively analyze the bone marrow characteristics of methimazole-induced agranulocytosis and other hematologic damage, and to explore its correlation with clinical features and prognosis.Methods:The bone marrow and clinical parameters of 20 patients of Graves′ disease diagnosed with methimazole-induced agranulocytosis at the First Affiliated Hospital of Xi′an Jiaotong University from January 2000 to December 2022 were collected. The intergroup differences in bone marrow characteristics and granulocyte recovery time were analyzed. Differences in peripheral blood and bone marrow characteristics between patients with single agranulocytosis and pancytopenia were compared. Besides, literature review of the bone marrow characteristics of methimazole-induced hematologic diseases was conducted.Results:Compared to patients with bone marrow characteristics of granulocyte and precursor maturation disorders(Type Ⅱ), patients with aplastic marrow(Type Ⅰ) had significant decreases in the proportions of granulocytes in all phases( P<0.05). Patients with bone marrow characteristics of Type Ⅰ had a significant increase in the proportion of the lymphocyte system [51.00%(41.50%, 75.50%) vs 22.00%(14.00%, 35.00%), P=0.002], and got a longer to recovery time [(6.58±1.68)d vs(3.71±1.60)d, P=0.003]; Correlation analysis suggested the granulocyte to erythrocyte ratio was negatively correlated with the granulocyte recovery time( r=-0.520, P=0.023), and the proportion of the bone marrow lymphocyte was positively correlated with granulocyte recovery time( r=0.622, P=0.004). Compared to patients with single agranulocytosis, patients with pancytopenia had a markedly longer hospital stay duration [(27.14±5.27)d vs(14.15±7.36)d, P=0.001]. Literature review suggestsed that methimazole may cause various degrees of damage to blood system and bone marrow. Conclusion:Methimazole can induce a variety of hematologic damages. Analysis of bone marrow characteristics can aid in further prognosis assessment. Clinicians should be vigilant about potential hematologic adverse reactions when using methimazole and promptly diagnose and treat them to prevent serious consequences.

[摘 要] 目的:探讨幽门螺杆菌(Helicobacter pylori, Hp)感染对胃癌细胞共济失调毛细血管扩张突变(ataxia-telangiectasia mutated,ATM)基因表达的影响及其临床意义。方法:从TCGA数据库中获取胃癌相关RNAseq数据,比较ATM基因的表达差异,分析ATM表达与患者临床病理参数的相关性及预后价值,用Kaplan-Meier法进行生存分析,LinkedOmics数据库分析ATM相关基因,用R语言进行GO、KEGG富集分析。选用2019年3月至2019年12月贵州医科大学附属医院12例手术切除的胃癌及癌旁组织标本,以及胃癌细胞系AGS和BGC823,用感染复数40∶1的Hp GZ7菌感染细胞,用免疫组织化学染色法检测胃癌组织中ATM蛋白的表达,qPCR法检测胃癌组织和细胞中ATM mRNA的表达。结果:TCGA数据显示胃癌和Hp感染胃癌组织中ATM miRNA表达水平均显著高于癌旁组织(均P<0.01);胃癌组织中ATM miRNA表达与患者的T分期、AJCC分期等病理参数呈正相关(均P<0.05),ATM高表达时生存率显著降低(P<0.05)。实验检测显示,胃癌组织标本中ATM蛋白的表达水平明显高于癌旁组织(P<0.01);Hp感染胃癌细胞中ATM miRNA表达水平显著高于未感染胃癌细胞(P<0.01)。胃癌中ATM基因与NPAT等12 461个基因呈正相关(P<0.05),与MIF等7 764个基因呈负相关(P<0.05)。GO、KEGG富集分析显示,ATM富集到DNA修复复合体、癌症中的转录失调等信号通路。结论:ATM基因在胃癌组织中高表达,患者生存率随表达水平的增高而降低,其与患者的T分期、AJCC分期等病理参数相关,且Hp感染引起ATM表达水平升高可能是Hp引起胃癌的原因之一。
