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 observe the efficacy and safety of goserelin combined with estradiol valerate in the treatment of endometriosis (EMs) in patients of childbearing age after laparoscopic surgery. METHODS The clinical data of 144 patients with EMs of childbearing age who underwent laparoscopic surgery in our hospital from January 2020 to December 2022 were collected retrospectively, and those patients were divided into control group (70 cases) and combination group (74 cases) based on different postoperative medication regimens. Control group was given Acetate goserelin sustained-release implant on the 1st to 5th day of their first menstrual cycle after laparoscopic surgery, while combination group was additionally given Estradiol valerate tablets on the basis of control group. The short-term and long-term efficacy of 2 groups were observed; preoperative and postoperative pain scores, ovarian reserve function, and the incidence of adverse reactions were all recorded in 2 groups. RESULTS There was no statistically significant difference in short-term total effective rate, 1-year postoperative recurrence rate and the incidence of decreased libido, vaginal dryness, gastrointestinal reactions, rash, or arrhythmia between two groups (P>0.05). The natural pregnancy rate of combination group was significantly higher than control group at 1 year after surgery, while the incidence E-mail:wanghuiling0518@126.com of early miscarriage, hot flashes and sweating, emotional fluctuations, insomnia and fatigue, joint muscle pain, dizziness and headache were significantly lower than control group (P<0.05). However, at 6 months after surgery, pain scores and the levels of anti-Müllerian hormone, follicle stimulating hormone, luteinizing hormone, estradiol of both groups were significantly lower than before surgery in the same group, while the number of antral follicle count was significantly higher than before surgery in the same group; the levels of anti-Müllerian hormone, luteinizing hormone, estradiol, and the number of antral follicles in the combination group were significantly higher than control group, while pain score and follicle stimulating hormone level were significantly lower than control group (P<0.05). CONCLUSIONS The combination of goserelin and estradiol valerate after laparoscopic surgery has a significant therapeutic effect and good safety in the treatment of EMs of childbearing age.

OBJECTIVE To predict the possible impact of pembrolizumab(PEM) as a first-line drug after being included in the national medical insurance system in the treatment of advanced or metastatic non-small cell lung cancer based on real-world data from the perspective of the national medical insurance payer, to provide a basis for the decision-making of the medical insurance department. METHODS A budget impact analysis model was constructed to compare the impact of pembrolizumab not included in medical insurance and included in medical insurance on medical insurance fund expenditure in the next five years( 2024- 2028) with 2023 as the baseline year. The target population was the patients with EGFR gene mutation-negative and anaplastic lymphoma kinase (ALK)-negative locally advanced or metastatic non-small cell lung cancer; estimated cost mainly included the cost of drugs, the cost of adverse reaction treatment, the cost of examination, the cost of admission and monitoring, etc; equipment ratio of PEM in 183 hospitals of Guangdong province from 2020 to 2022 was used as the market share. Univariate sensitivity analysis was used to test the robustness of the basic analysis results. RESULTS When PEM was not included in the medical insurance, the medical insurance reimbursement amount of the target population from 2024 to 2028 was 4 933 623.5 thousand yuan-5 151 198.3 thousand yuan, respectively. If PEM was included in the medical insurance, the above data were 11 871 972.2 thousand yuan-14 540 571.0 thousand yuan, respectively; the increase in medical insurance reimbursement under the two scenarios was 6 720 773.9 thousand yuan-9 606 947.5 thousand yuan, respectively. The proportion of medical insurance reimbursement to the medical insurance expenditure of the year after PEM was included in medical insurance was 0.298 0%, 0.262 1%, 0.228 8%, 0.208 2%, and 0.185 7%, respectively. The increase in medical insurance reimbursement accounted for 1.084 0%, 0.995 7%, 0.888 6%, 0.886 3%, and 0.861 6% of the increase in the expenditure of the medical insurance fund in the current year, all of which showed a decreasing trend year by year. CONCLUSIONS If PEM is included in medical insurance, due to its high unit price, the medical expenditure will increase accordingly, which will have a great impact on the medical insurance fund expenditure. However, when the drug is used in patients with EGFR mutation-negative and ALK-negative locally advanced or metastatic non-small cell lung cancer, the proportion of the medical insurance reimbursement amount in the current year’s medical insurance fund expenditure and the proportion of the increase in medical insurance reimbursement in the current year’s increase in medical insurance fund expenditure are decreasing year by year.

Objective:To explore the role of mechanical hemodynamic support (MHS) in mapping and catheter ablation of patients with hemodynamically unstable ventricular tachycardia (VT), report single-center experience in a cohort of consecutive patients receiving VT ablation during MHS therapy, and provide evidence-based medical evidence for clinical practice.Methods:This was a retrospective cohort study. Patients with hemodynamically unstable VT who underwent catheter ablation with MHS at Beijing Anzhen Hospital, Capital Medical University between August 2021 and December 2023 were included. Patients were divided into rescue group and preventive group according to the purpose of treatment. Their demographic data, periprocedural details, and clinical outcomes were collected and analyzed.Results:A total of 15 patients with hemodynamically unstable VT were included (8 patients in the rescue group and 7 patients in the preventive group). The acute procedure was successful in all patients. One patient in the rescue group had surgical left ventricular assist device (LVAD) implantation, remaining 14 patients received extracorporeal membrane oxygenation (ECMO) for circulation support. ECMO decannulation was performed in 12 patients due to clinical and hemodynamic stability, of which 6 patients were decannulation immediately after surgery and the remaining patients were decannulation at 2.0 (2.5) d after surgery. Two patients in the rescue group died during the index admission due to refractory heart failure and cerebral hemorrhage. During a median follow-up of 30 d (1 d to 12 months), one patient with LVAD had one episode of ventricular fibrillation at 6 months after discharge, and no further episodes of ventricular fibrillation and/or VT occurred after treatment with antiarrhythmic drugs. No malignant ventricular arrhythmia occurred in the remaining 12 patients who were followed up.Conclusions:MHS contributes to the successful completion of mapping and catheter ablation in patients with hemodynamically unstable VT, providing desirable hemodynamic status for emergency and elective conditions.

Intervertebral disc degeneration(IDD) is the pathological basis of spinal diseases. With the development and change of working and living style, IDD gradually presents the trend of younger in recent years. The effective prevention and treatment of IDD has become a hotspot in clinical research. Recent studies have shown that oxidative stress plays an important role in IDD. The disruption of reactive oxygen species balance in cells or the body leads to changes in extracellular matrix and intervertebral disc cell phenotype, which induces oxidative stress of intervertebral disc and leads to IDD. Oxidative stress can affect the development of IDD through apoptosis, autophagy, senescence and extracellular matrix of intervertebral disc. Currently, opioids and drugs for promoting blood circulation and pain relief are commonly used in clinical treatment of IDD, which can alleviate some symptoms to a certain extent, but is easy to induce gastrointestinal and other adverse reactions. Meanwhile, due to the long treatment cycle and poor patient compliance to a certain extent, which brings great difficulties to the treatment. At the same time, traditional Chinese medicine plays an important role in the treatment of IDD due to its advantages of low cost and fewer adverse reactions. With the in-depth research of modern technologies such as molecular biology and network pharmacology, it has been found that traditional Chinese medicine can intervene in the expression of oxidative stress-related functions, namely, slowing down apoptosis, autophagy and degradation of extracellular matrix, etc, to play a role in the treatment of IDD. In this paper, the role of oxidative stress in IDD and the research results on the intervention of traditional Chinese medicine in oxidative stress will be expounded, in order to provide reference for the prevention and treatment of IDD by traditional Chinese medicine.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
