Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

Objective To investigate the renal function recovery and perioperative risk factors for chronic kidney disease in patients after acute Stanford type A aortic dissection (ATAAD) repair. Methods A retrospective study was conducted on patients who underwent ATAAD repair at the Xiamen Cardiovascular Hospital, Xiamen University from 2020 to 2021, and their clinical data were analyzed. Results A total of 255 patients were included, with 200 males and 55 females, and an average age of (52.80±12.46) years. The incidence of acute kidney injury (AKI) after ATAAD repair was 43.9%. Dissection involving the renal artery [OR=2.144, 95%CI (1.234, 3.765), P=0.007], intraoperative urine output [OR=0.761, 95%CI (0.625, 0.911), P=0.004], and intraoperative red blood cell transfusion [OR=1.288, 95%CI (1.088, 1.543), P=0.004] were significantly associated with early AKI after ATAAD repair. Long-term renal function follow-up data were available for 232 patients, among whom 40 (17.2%) patients developed chronic kidney disease (CKD). Independent predictors for CKD included lower body mass index [OR=0.827, 95%CI (0.723, 0.931), P=0.003], preoperative cardiac tamponade [OR=5.344, 95%CI (1.65, 17.958), P=0.005], preoperative renal hypoperfusion syndrome [OR=12.629, 95%CI (5.003, 35.373), P<0.001], postoperative peak serum creatinine time>3 d [OR=7.566, 95%CI (2.799, 22.731), P<0.001], and AKI grade [grade 1: OR=4.418, 95%CI (1.339, 15.361), P=0.016; grade 2: OR=8.345, 95%CI (1.762, 40.499), P=0.007; grade 3: OR=9.463, 95%CI (2.602, 37.693), P<0.001]. Conclusion AKI related to ATAAD repair can recover in the early postoperative period, but both the duration and severity of AKI will affect long-term renal function. In addition, patients' nutritional status, preoperative cardiac tamponade, and renal hypoperfusion syndrome are also independent risk factors for long-term renal dysfunction.

Cardiac arrest (CA) is a critical condition in the field of cardiovascular medicine. Despite successful resuscitation, patients continue to have a high mortality rate, largely due to post CA syndrome (PCAS). However, the injury and pathophysiological mechanisms underlying PCAS remain unclear. Experimental animal models are valuable tools for exploring the etiology, pathogenesis, and potential interventions for CA and PCAS. Current CA animal models include electrical induction of ventricular fibrillation (VF), myocardial infarction, high potassium, asphyxia, and hemorrhagic shock. Although these models do not fully replicate the complexity of clinical CA, the mechanistic insights they provide remain highly relevant, including post-CA brain injury (PCABI), post-CA myocardial dysfunction (PAMD), systemic ischaemia/reperfusion injury (IRI), and the persistent precipitating pathology. Summarizing the methods of establishing CA models, the challenges encountered in the modeling process, and the mechanisms of PCAS can provide a foundation for developing standardized CA modeling protocols.

OBJECTIVE: To explore the clinical features of the sepsis in immunocompromised hosts and establish an early warning equation. METHODS: A retrospective study was conducted on sepsis patients admitted to the intensive care unit (ICU) of Binzhou Medical University Hospital from October 2011 to October 2022. General information, infection site, etiology results and drug susceptibility, clinical symptoms, inflammatory indicators, acute physiology and chronic health status evaluation II (APACHE II), sequential organ failure assessment (SOFA), incidence of immune paralysis, and outcome during hospitalization were collected. Based on whether they met the diagnostic criteria for immunocompromised hosts, patients were divided into immunocompromised group and immune normal group. The clinical information of the two groups were compared. Multivariate Logistic regression was used to analyze the risk factors of patients with immunocompromised sepsis and the regression equation model was initially established. Omnibus test and Hosmer-Lemeshow test were used to evaluate the model. RESULTS: A total of 169 patients with sepsis were included, including 61 in the immunocompromised group and 108 in the normal immune group. The top 3 infection sites in the immunocompromised group were bloodstream infection, pulmonary infection and abdominal infection. The top 3 infection sites in the normal immune group were pulmonary infection, bloodstream infection and abdominal infection. The infection rate of Gram-negative bacteria in the immunocompromised group was significantly lower than that in the normal group [49.2% (30/61) vs. 64.8% (70/108), P < 0.05]. The infection rate of Gram-positive bacteria [27.9% (17/61) vs. 13.9% (15/108)] and multidrug-resistant bacteria [54.1% (33/61) vs. 29.6% (32/108)] were significantly higher than those in normal immune group (both P < 0.05). In terms of clinical symptoms, the proportion of fever in the immunocompromised group was significantly lower than that in the immune normal group [49.2% (30/61) vs. 66.7% (72/108), P < 0.05]. Neutrophil count (NEU) and neutrophil percentage (NEU%) in the immunocompromised group were significantly lower than those in the normal immune group. Lymphocyte percentage (LYM%), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), APACHE II score, combined shock rate, incidence of immune paralysis, and mortality during hospitalization in the immunocompromised group were significantly higher than those in the normal immune group. Logistic regression analysis showed that NLR, CRP and PCT were risk factors for patients with immunocompromised sepsis (all P < 0.05). The above indicators were used as covariables to construct a Logistic regression equation, that was, Logit (P) = 0.025X₁+0.010X₂+0.013X₃-2.945, where X₁, X₂ and X₃ represent NLR, CRP and PCT respectively. Omnibus test and Hosmer-Lemeshow test show that the model fits well and has certain early warning value. CONCLUSIONS Patients with immunocompromised sepsis have more intense inflammatory response, with Gram-negative bacteria being the predominant pathogen, and a higher incidence of Gram-positive bacterial infections and multi-drug resistant infections. The severity of the disease, in-hospital mortality, the incidence of shock and the incidence of immune paralysis after sepsis were significantly higher. NLR, CRP and PCT were independent risk factors for sepsis in immunocompromised hosts. The regression equation constructed based on this may have early warning significance for patients with immunocompromised sepsis.

Objective:To investigate the anemia conditions and characteristics of iron metabolism during different stages of pregnancy in women with different genotypes of thalassemia.Methods:This cohort study selected 3 303 singleton pregnant women who underwent regular prenatal examinations and genetic tests of thalassemia and were delivered at Maternal & Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2019 to December 2023. According to the results of thalassemia gene testing, the women were divided into groups: those without thalassemia genes served as the control group (1 539 cases), and those with thalassemia genes (1 764 cases) were further divided based on genotype into the -α/αα group (326 cases), --/αα or -α/-α group (649 cases), point mutation α-thalassemia group (201 cases), β 0-thalassemia group (368 cases), β +-thalassemia group (91 cases), and α combined with β-thalassemia group (129 cases). Hemoglobin (Hb) and serum ferritin (SF) levels were measured in the first, second, and third trimester of pregnancy. Differences in anemia and iron reserves among the groups at different pregnancy stages were compared using repeated measures analysis of variance, LSD test, Kruskal-Wallis rank-sum test, and Bonferroni correction. Results:Compared to the first trimester, Hb levels decreased in the second and third trimester across all groups (LSD test, all P<0.05), and the severity of anemia increased (Bonferroni correction, all P<0.017). The severity of anemia varied among the groups at the same pregnancy stage ( Hfirst trimester=918.20, Hsecond trimester=1 224.50, Hthird trimester=980.19; all P<0.001), and Hb levels also differed ( Ffirst trimester=282.54, Fsecond trimester=352.31, Fthird trimester=239.02; all P<0.001). The β 0-thalassemia group had higher rates of moderate anemia in the first, second, and third trimester of pregnancy [38.6% (142/368), 85.3% (314/368), and 73.6% (271/368)] compared to other groups (Bonferroni correction, all P<0.002), and lower Hb levels [(102.1±8.9), (92.0±7.3), and (94.6±7.7) g/L] than other groups (LSD test, all P<0.05). As pregnancy progresses, SF levels in each group of pregnant women gradually decreased (LSD test, all P<0.05), and the degree of iron deficiency worsened (Bonferroni correction, all P<0.05). The iron deficiency rate in thalassemia pregnant women during the third trimester ranges from 21.5% (79/368) to 46.0% (150/326). The degree of iron deficiency varies among groups within the same gestational period ( Hfirst trimester=79.13, Hsecond trimester=203.98, Hthird trimester=130.55; all P<0.001), and SF levels also differ ( Ffirst trimester=17.28, Fsecond trimester=44.60, Fthird trimester=31.87; all P<0.001). Among them, the β 0-thalassemia group had the lowest iron deficiency rates in the second, and third trimesters [9.8% (36/368), and 21.5% (79/368)] (Bonferroni correction, all P<0.002). SF levels in the β 0-thalassemia and β +-thalassemia groups were higher than those in other groups during each gestational period (LSD test, all P<0.05). Conclusions:Pregnant women with thalassemia may experience varying degrees of iron deficiency during pregnancy, with the severity of iron deficiency and anemia increasing with gestational age. The degree of iron deficiency and anemia during pregnancy varies among pregnant women with different genotypes of thalassemia. Clinically, individualized management should be provided for pregnant women with thalassemia based on their genotypes, with dynamic monitoring of anemia and iron metabolism changes.

OBJECTIVE To investigate the current status of water management for terminal rinsing of digestive en-doscope in medical institutions in Fujian Province,and to provide reference for improving regional quality control standards.METHODS An electronic questionnaire survey was conducted from Jul.2024 to Aug.2024 through convenient sampling in secondary and above hospitals of 9 prefecture-level cities in Fujian Province.The survey covered topics such as water treatment system configuration,maintenance and water quality monitoring.RESULTS A total of 108 questionnaires were distributed and 104 valid questionnaires were collected,with an effec-tive response rate of 96.30％.The survey revealed that 78.85％(82/104)of the hospitals adopted separate water supply for each department,and 82.69％used purified water for terminal rinsing.Only 19.23％installed the final filter membrane at the water outlet.In addition,66.35％of the hospitals did not specify the service life of the wa-ter supply pipeline,and the pipeline disinfection implementation rate was 60.58％,but 31.75％of them had ir-regular disinfection frequencies,with chlorine-based disinfectants(50.79％)and peracetic acid(34.92％)being the main disinfectants.The regular conductivity monitoring rate was 47.12％,and the microbial monitoring cov-erage rate reached 90.38％,with the monitoring frequency mainly being once every quarter(60.64％),but only 20.21％used R2A medium,and 12.77％adopted the membrane filtration method for inoculation.Tertiary hospi-tals were superior to secondary hospitals in terms of film membrane pore size pass rate(87.50％vs.56.86％),pipeline disinfection implementation rate(71.43％vs.50.91％)and advanced detection method application(P＜0.05).CONCLUSIONS There are issues in the management of water used for terminal rinsing of digestive endo-scopes in Fujian Province,including non-standard equipment maintenance,inconsistent monitoring methods and insufficient awareness among management personnel.It is recommended to enhance management quality by optimizing the water treatment system setup,establishing standardized monitoring procedures and strengthening professional training for personnel.

Objective:To investigate the clinical-epidemiological characteristics of connective tissue diseases (CTD) complicated with pulmonary hypertension in Shanxi province from 2018 to 2021.Methods:This was a cross-sectional study. Data of CTD patients with pulmonary hypertension from 2018 to 2021 were collected from the Shanxi Provincial Health Statistics Direct Reporting System based on inpatient medical records. The demographic and clinical data of patients with different CTD types were analyzed.Results:A total of 1 697 CTD patients with pulmonary hypertension were included, among whom there were 451 cases (26.58%) of Sj?gren′s syndrome, 392 cases (23.10%) of systemic lupus erythematosus, 289 cases(17.03%) of systemic sclerosis, 109 cases (6.42%) of mixed CTD, 69 cases (4.07%) of Takayasu arteritis, and 387 cases (22.80%) of other CTD. The majority of patients were female (1 410 (83.09%)), and 783 cases (46.14%) were aged between 41 and 65 years, and 6 cases (0.35%) were performed right heart catheterization. The prevalence of CTD with pulmonary hypertension increased from 0.06/10 4 in 2018 to 0.20/10 4 in 2021. There were significant differences in the severity of pulmonary hypertension, New York Heart Association (NYHA) functional class, length of hospital stay, medical costs, and clinical outcomes among patients with different CTD subtypes (all P<0.001). Patients with systemic sclerosis had the highest proportion of NYHA functional class Ⅲ/Ⅳ(65.1%(188/289)), the longest length of hospital stays (13 (9, 18) days), the highest average medical costs (13 622.67 (8 636.38, 20 597.75) ￥(RMB)), and the lowest rate of improvement and discharge (51.90%(150/289)). Conclusions:Between 2018 and 2021, Shanxi province, where CTD is more common in Sj?gren′s syndrome, has a high proportion of women, a high proportion of people aged 41-65 years, and a low prevalence of right ventricular catheterization in patients with CTD complicated with pulmonary hypertension. The prevalence of CTD complicated with pulmonary hypertension shows a rising trend in Shanxi province from 2018 to 2021, while patients with systemic sclerosis exhibit the most severe cardiac impairment and poorer clinical outcomes compared to other subtypes.

Objective Based on the propensity score matching(PSM),the effect of flexible ureteroscopy combined with flexible negative pressure suction sheath in the treatment of infectious renal calculus lithotomy was analyzed.Methods From April 2022 to April 2024,87 patients with infectious renal calculus in our hospital were selected retrospectively.All patients were treated with flexible ureteroscopic lithotripsy(FURL).According to the different choice of ureteral access sheath(UAS)during operation,they were divided into negative pressure sheath group(n=43)and conventional sheath group(n=44).In the negative pressure sheath group,the flexible negative pressure suction sheath was used for FURL,and in the conventional sheath group,the conventional sheath was used for FURL.The general data of patients with infectious renal calculus between groups were compared,and the indicators were balanced by PSM.The clinical efficacy,perioperative indicators,levels of procalcitonin(PCT)and white blood cell count(WBC)and postoperative complications of patients with infectious renal calculus were compared between the two groups.Results After 1∶1 ratio matching by PSM,42 pairs of patients with infectious renal calculus were obtained,.The stone clearance rate of negative pressure sheath group[90.48%(38/42)]was significantly higher than that of conventional sheath group[71.43%(30/42)](P<0.05).The minimum intrapelvic pressure,average intrapelvic pressure and maximum intrapelvic pressure in the negative pressure sheath group were lower than those in the conventional sheath group,operation time and hospitalization time in the negative pressure sheath group were shorter than those in the conventional sheath group(P<0.05).The levels of PCT and WBC in the negative pressure sheath group were lower than those in the conventional sheath group at 2 h after operation,and the time for PCT and WBC to recover to the normal level were shorter than those in the conventional sheath group(P<0.05).The total incidence of postoperative complications in negative pressure sheath group[9.52%(4/42)]was significantly lower than that in conventional sheath group[28.57%(12/42)](P<0.05).Conclusion Flexible ureteroscopy combined with flexible negative pressure suction sheath is effective in the treatment of renal calculus,which is helpful to reduce intra-operative renal pelvis pressure,shorten operation time,reduce PCT and WBC levels after operation,and promote patients'early recovery with good safety.

Objective To investigate the clinical characteristics and prognostic factors of Staphylococcus aureus bloodstream infections in adult patients for improving clinical treatment and identifying potential interventions.Methods Clinical data of inpatients diagnosed with S.aureus bloodstream infection confirmed by blood culture in a hospital from January 2016 to December 2023 were retrospectively reviewed.The data included patient age,gender,history of hospital admission,department of admission,underlying diseases,primary infection,quick Pitt bacteremia score(qPitt),invasive treatment,empirical anti-infective treatment,and treatment outcomes.Patients were assigned to case group or control group according to whether they died in hospital in order to identify the prognostic factors of patient outcomes.Binary logistic regression analysis was used to identify independent prognostic factors.Results A total of 233 cases of S.aureus bacteremia were identified.Multivariate logistic regression analysis showed that age ≥ 70 years old(OR=4.725,95％CI:1.228-18.173,P=0.024),diabetes mellitus(OR=8.161,95％CI:1.954-34.086,P=0.004),Charlson comorbidity index(CCI)≥ 5(OR=7.672,95％CI:1.901-30.963,P=0.004),hospital infection(OR=7.853,95％CI:1.588-38.832,P=0.012),and qPitt ≥ 2(OR=23.189,95％CI:4.461-120.552,P＜0.001)were independent prognostic factors for poor outcome of patients with S.aureus bacteremia,while catheter-associated infection(OR=0.051,95％CI:0.005-0.579,P=0.016)was negatively correlated with mortality.Conclusions Advanced age,diabetes mellitus,high CCI,hospital infection,and high qPitt were independent prognostic factors for poor outcomes of patients with S.aureus bacteremia.The patients should be well managed by timely removal of eradicable lesions to improve patient outcomes.
