OBJECTIVE To analyze the prevalence of hospital-associated carbapenem-resistant Enterobacter(CRE)infections among the elderly intensive care unit(ICU)patients with respiratory system diseases based on the Chinese healthcare security diagnosis-related groups(CHS-DRG)and the case mix index(CMI)and assess the economic burden and consumption of healthcare insurance funds.METHODS The key departments with high isola-tion rate of CRE and high incidence of hospital-associated infections were found out by using CMI.The data were collected from 56 elderly patients with major diagnostic category E(MDCE)who had hospital-associated Enter-obacter infection and were treated in 10 ICUs of the Second People's Hospital of Changzhou from 2021 to 2023.The length of hospital stay,economic burden and consumption of healthcare insurance funds were observed and compared between the CRE infection group and the carbapenem-sensitive Enterobacter(CSE)infection group.RESULTS The general ICU(Yanghu campus)ranked the top 3 isolation rate of CRE and incidence of hospital-associated in-fections after the adjustment of CMI value.EJ1(other respiratory system surgeries)and ES2(respiratory sys-tem infection/inflammation)were the core codes of major Enterobacter infection.The average length of hospital stay of the CRE group was 10 days larger than the CSE group,the self-funded amount was 20,777.65 yuan more in the CRE group than in the CSE group;the consumption of healthcare insurance funds was 39,631.64 yuan more in the CRE group than in the CSE group(P＜0.05).Of the patients encoded with ES2,the average length of hospital stay was 6.5 days more in the CRE group than in the CSE group,and the fund expense on pay-ment of severe diseases was greater in the CRE group than in the CSE group(P＜0.05).CONCLUSIONS The CRE infection may increase the length of hospital stay,economic burden and consumption of healthcare insurance funds of the elderly ICU patients with respiratory system diseases.Under the CHS-DRG payment mode,it is nec-essary to take targeted prevention and control strategies according to the characteristics of patients with different DRG codes so as to control the wide spread of CRE.

Objective:To investigate lipid metabolism gene mutations and pathogenicity of hypertriglyceridemia acute pancreatitis (HTG-AP) patients.Methods:Clinical data of 495 HTG-AP patients admitted from June 2018 to June 2020 in the center for severe acute pancreatitis of Eastern Theater General Hospital were retrospectively analyzed. Whole-exome sequencing and mutation verification were performed by next-generation sequencing technology and Sanger sequencing. The pathogenicity of gene mutation was analyzed by population mutation ratio, pathogenicity prediction software, conservation scoring software, protein structure prediction, and in vitro experiments. Results:The mutation ratio of lipid metabolism-related genes, namely LPL, APOA5, LMF1, GPIHBP1, and APOC2, were 14.81%, 55.78%, 43.61%, 1.62%, and 0.61%, respectively. Among them, 44 heterozygous mutations in LPL gene were detected including 36 missense mutations, 5 nonsense mutations and 3 frameshift mutations, which were all rarely carried in single patient. Six HTG-AP patients carried the LPL gene heterozygous mutation c.835C>G (p.Leu279Val). The mean level of serum triglyceride at the onset of HTG-AP was 27.4 mmol/L. All of them had a history of recurrent HTG-AP, and most of them had severe acute pancreatitis. The serum LPL concentration and activity were lower than the normal level. The pathogenicity analysis results suggested that the LPL p.Leu279Val was a rare, highly possible pathogenic and highly conserved gene mutation. The in vitro results showed that the LPL p.Leu279Val could significantly reduce the synthesis and secretion ability of LPL as well as its enzymatic activity. Conclusions:The mutation ratio of lipid metabolism-related genes, including LPL, APOA5, LMF1, GPIHBP1, and APOC2, are relatively high in the HTG-AP patients. The LPL p.Leu279Val is a rare and highly possible pathogenic gene mutation, which may lead to recurrent episodes of HTG-AP.

Objective:To identify risk factors for developing infected pancreatic necrosis (IPN) in female hypertriglyceridemia-induced acute pancreatitis (HTG-AP) patients with childbearing age.Methods:A retrospective analysis was conducted on clinical data from 460 female HTG-AP patients with childbearing age admitted to Eastern Theater General Hospital of the Chinese People's Liberation Army between December 2013 and December 2022. Patients were divided into the IPN group ( n=140) and non-IPN group ( n=320) based on the occurrence of IPN. General clinical data, laboratory test results and clinical outcomes were compared between the two groups. Univariate and multivariate logistic regression models were used to analyze the risk factors for IPN in reproductive-age HTG-AP patients. Results:Among the 460 patients, 140 (30.4%) developed IPN. Compared with the non-IPN group, the IPN group had a significantly higher proportion of pregnant patients (30.0% vs 10.9%, P<0.001) and a lower proportion with a history of acute pancreatitis (12.9% vs 31.3%, P<0.001). Laboratory findings showed that patients in the IPN group had lower levels of hemoglobin and albumin, but higher levels of blood urea nitrogen and serum creatinine. Clinical outcomes showed that the IPN group had significantly higher rates of severe acute pancreatitis and mortality compared to the non-IPN group. Additionally, the median length of ICU stay and total hospital stay in the IPN group were significantly longer, at 16.5 days and 32.0 days, respectively. Univariate logistic regression analyses showed that pregnancy, previous history of acute pancreatitis, and levels of hemoglobin, total bilirubin, albumin, blood urea nitrogen and creatinine were significantly associated with IPN. Multivariate logistic regression analysis revealed that pregnancy ( OR=2.617, 95% CI 1.494-4.210, P=0.001), a history of acute pancreatitis ( OR=0.339, 95% CI 0.189-0.711, P=0.002), hemoglobin level ( OR=0.945, 95% CI 0.939-0.987, P<0.001), and blood urea nitrogen level ( OR=1.173, 95% CI 1.056-1.198, P=0.004) were independently associated with the occurrence of IPN. Conclusions:Pregnancy, a first episode of acute pancreatitis, lower hemoglobin levels and higher blood urea nitrogen levels are independent risk factors for IPN in female HTG-AP patients with childbearing age.

ObjectiveTo investigate the distribution and trend of rehabilitation personnel of China Disabled Persons' Federation (CDPF) system and the people with disabilities (PWDs) using geographical gravity model. MethodsBased on ArcGIS and statistical data, the distribution of geographical center of gravity of the rehabilitation personnel of the CDPF system from 2011 to 2021 was analyzed. According to the economic development, the areas were divided into three regions, and the eastern region included eleven provincial units, the central region includes eight provincial units, and the western region included twelve provincial units. ResultsCompared with 2011, rehabilitation staffs per thousand PWDs increased at 107.5% in 2021, 81.1%, 114.2% and 174.1% for the eastern, central, and western regions, respectively; professional staffs increased at 190.5%, 148.8%, 284.6% and 280.6% for the eastern, central, and western regions, respectively; managerial staff increased at 80.0%, 46.8%, 554.3% and 128.1% for the eastern, central, and western regions, respectively. Compared with 2011, the geographical center of gravity of the rehabilitation personnel moved about 330.9 km in 2021, while the geographical center of gravity of the PWDs moved about 169.64 km. ConclusionThe rehabilitation personnel in the CDPF system is the most in the eastern region and least in the western region. The tracks of the geographical center of gravity of the three kind of rehabilitation personnel in the CDPF system are relatively consistent. The rehabilitation personnel in the eastern region are more concentrated than those in the western region, and the density of the PWDs is more westward than that of the rehabilitation personnel, and coordination is not a perfect match yet. It is necessary to strengthen the rehabilitation personnel allocation in the western region, to balance distribution of human resources for rehabilitation of PWDs among regions.

A simple, fast, and visual method for detecting antibodies against peste des petits ruminants virus (PPRV) using colloidal gold strips was developed. In this study, the pET-32a-N was transformed into Escherichia coli Rosetta (DE3) for expression. Hybridoma cell lines were generated by fusing SP2/0 myeloma cells with splenocytes from immunized mice with the expressed and purified N protein of PPRV. The PPRV N protein was labeled with colloidal gold particles as the gold-labeled antigen. The N protein served as the gold standard antigen and as the test (T) line-coated antigen, while the monoclonal antibody served as the quality control (C) line-coated antibody to assemble the colloidal gold immunochromatographic test strips for detecting antibodies against the N protein of PPRV. Hybridoma cell line designated as 1F1 was able to stably secrete the monoclonal antibody against the N protein of PPRV. The titer of 1F1 monoclonal antibody in ascites was 1:128 000 determined by indirect enzyme-linked immunosorbent assays (ELISA), and the immunoglobulin subtype of the monoclonal antibody was IgG1, with kappa chain. The obtained monoclonal antibody was able to specifically recognize the N protein of PPRV, as shown by Western blotting and indirect immunofluorescent assay (IFA). The developed colloidal gold test strip method was able to detect PPRV antibodies specifically, and there was no difference between different batches of the test strips. Testing of a total of 122 clinical sera showed that the compliance rate of the test strip with ELISA test was 97.6%.The test strip assay developed in this study has good specificity, reproducibility, and sensitivity, and it can be used for the rapid detection of PPRV antibodies.

BACKGROUND: Congenital heart disease (CHD) is one of the most common congenital malformations in humans. Inconsistent results emerged in the existed studies on associations between air pollution and congenital heart disease. The purpose of this study was to evaluate the association of gestational exposure to air pollutants with congenital heart disease, and to explore the critical exposure windows for congenital heart disease. METHODS: The nested case-control study collected birth records and the following health data in Tianjin Women and Children's Health Center, China. All of the cases of congenital heart disease from 2013 to 2015 were selected matching five healthy controls for each case. Inverse distance weighting was used to estimate individual exposure based on daily air pollution data. Furthermore, the conditional logistic regression with distributed lag non-linear model was performed to identify the association between gestational exposure to air pollution and congenital heart disease. RESULTS: A total of 8,748 mother-infant pairs were entered into the analysis, of which 1,458 infants suffered from congenital heart disease. For each 10 µg/m³ increase of gestational exposure to PM_2.5, the ORs (95% confidence interval, 95%CI) ranged from 1.008 (1.001-1.016) to 1.013 (1.001-1.024) during the 1^st-2^nd gestation weeks. Similar weak but increased risks of congenital heart disease were associated with O₃ exposure during the 1^st week and SO₂ exposure during 6^th-7^th weeks in the first trimester, while no significant findings for other air pollutants. CONCLUSIONS This study highlighted that gestational exposure to PM_2.5, O₃, and SO₂ had lag effects on congenital heart disease. Our results support potential benefits for pregnancy women to the mitigation of air pollution exposure in the early stage, especially when a critical exposure time window of air pollutants may precede heart development.
