ObjectiveTo analyze the factors influencing meropenem-related liver injury （MRLI） and to explore their clinical predictive value. MethodsA retrospective case-control study was conducted， and the Chinese Hospital Pharmacovigilance System （CHPS） was used to establish a retrieval scheme. A total of 1 625 hospitalized cases using meropenem from January 2018 to December 2022 were collected. Patients were divided into case group （n=62） and control group （n=1 563） based on the presence or absence of liver injury. Clinical data and laboratory indicators from both groups were collected and analyzed. The t-test was used for comparison of normally distributed continuous data between the two groups， while the Mann-Whitney U test was used for comparison of continuous data not conforming to a normal distribution. The chi-square test was used for comparison of categorical data between the two groups. A multivariate Logistic regression analysis was performed to identify the influencing factors for MRLI. A Logistic regression equation was established， and the predictive value of these factors was assessed using the receiver operating characteristic （ROC） curve. ResultsThe results of univariate analysis indicated that the rates of male patients， hypoproteinemia， shock， intensive care unit （ICU） admissions， sepsis， and liver， gallbladder， and cardiovascular diseases， the levels of alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， gamma-glutamyl transpeptidase （GGT）， aspartate aminotransferase （AST）， creatinine （CREA）， and procalcitonin （PCT）， and the number of hospitalization days were significantly higher in the case group than in the control group （P<0.05）， and that the platelet levels in the case group were significantly lower than those in the control group （P<0.05）. The multivariate Logistic regression analysis showed that male sex （odds ratio ［OR］=2.080， 95% confidence interval ［CI］： 1.050 — 4.123， P=0.036）， admission to the ICU （OR=8.207， 95%CI： 4.094‍ ‍—‍ ‍16.453， P<0.001）， comorbidity with gallbladder disease （OR=8.240， 95%CI： 3.605‍ ‍—‍ ‍18.832， P<0.001）， ALP （OR=1.012， 95%CI： 1.004‍ ‍—‍ ‍1.019， P=0.004）， GGT （OR=1.010， 95%CI： 1.005‍ ‍—‍ ‍1.015， P<0.001）， and PLT （OR=0.997， 95%CI： 0.994‍ ‍—‍ ‍0.999， P=0.020） were the influential factors for MRLI. The areas under the ROC curve of ALP， GGT， and PLT were 0.589， 0.637， and 0.595， respectively， and the AUC of them combined was 0.837. ConclusionMale sex， ICU admission， comorbidity with gallbladder disease， increased ALP， increased GGT， and decreased PLT were influencing factors for MRLI， and a combination of factors has a better predictive value for the occurrence of MRLI.

BACKGROUND: The FAVOR (Comparison of Quantitative Flow Ratio Guided and Angiography Guided Percutaneous Intervention in Patients with Coronary Artery Disease) III China trial demonstrated that percutaneous coronary intervention (PCI) lesion selection using quantitative flow ratio (QFR) measurement, a novel angiography-based approach for estimating fractional flow reserve, improved two-year clinical outcomes compared with standard angiography guidance. This study aimed to assess the cost-effectiveness of QFR-guided PCI from the perspective of the current Chinese healthcare system. METHODS: This study is a pre-specified analysis of the FAVOR III China trial, which included 3825 patients randomized between December 25, 2018, and January 19, 2020, from 26 centers in China. Patients with stable or unstable angina pectoris or those ≥72 hours post-myocardial infarction who had at least one lesion with a diameter stenosis between 50% and 90% in a coronary artery with a ≥2.5 mm reference vessel diameter by visual assessment were randomized to a QFR-guided strategy or an angiography-guided strategy with 1:1 ratio. During the two-year follow-up, data were collected on clinical outcomes, quality-adjusted life-years (QALYs), estimated costs of index procedure hospitalization, outpatient cardiovascular medication use, and rehospitalization due to major adverse cardiac and cerebrovascular events (MACCE). The primary analysis calculated the incremental cost-effectiveness ratio (ICER) as the cost per MACCE avoided. An ICER of ¥10,000/MACCE event avoided was considered economically attractive in China. RESULTS: At two years, the QFR-guided group demonstrated a reduced rate of MACCE compared to the angiography-guided group (10.8% vs . 14.7%, P <0.01). Total two-year costs were similar between the groups (¥50,803 ± 21,121 vs . ¥50,685 ± 23,495, P = 0.87). The ICER for the QFR-guided strategy was ¥3055 per MACCE avoided, and the probability of QFR being economically attractive was 64% at a willingness-to-pay threshold of ¥10,000/MACCE avoided. Sensitivity analysis showed that QFR-guided PCI would become cost-saving if the cost of QFR were below ¥3682 (current cost: ¥3800). Cost-utility analysis yielded an ICER of ¥56,163 per QALY gained, with a 53% probability of being cost-effective at a willingness-to-pay threshold of ¥85,000 per QALY gained. CONCLUSION: In patients undergoing PCI, a QFR-guided strategy appears economically attractive compared to angiographic guidance from the perspective of the Chinese healthcare system.

Given that ovarian stimulation is vital for assisted reproductive technology (ART) and results in elevated serum estrogen levels, exploring the impact of elevated estrogen exposure on oocytes and embryos is necessary. We investigated the effects of various ovarian stimulation treatments on oocyte and embryo morphology and gene expression using a mouse model and estrogen-treated mouse embryonic stem cells (mESCs). Female C57BL/6J mice were subjected to two types of conventional ovarian stimulation and ovarian hyperstimulation; mice treated with only normal saline served as controls. Hyperstimulation resulted in high serum estrogen levels, enlarged ovaries, an increased number of aberrant oocytes, and decreased embryo formation. The messenger RNA (mRNA)‍-sequencing of oocytes revealed the dysregulated expression of lysine-specific demethylase 6b (Kdm6b), which may be a key factor indicating hyperstimulation-induced aberrant oocytes and embryos. In vitro, Kdm6b expression was downregulated in mESCs treated with high-dose estrogen; treatment with an estrogen receptor antagonist could reverse this downregulated expression level. Furthermore, treatment with high-dose estrogen resulted in the upregulated expression of histone H3 lysine 27 trimethylation (H3K27me3) and phosphorylated H2A histone family member X (γ-H2AX). Notably, knockdown of Kdm6b and high estrogen levels hindered the formation of embryoid bodies, with a concomitant increase in the expression of H3K27me3 and γ-H2AX. Collectively, our findings revealed that hyperstimulation-induced high-dose estrogen could impair the demethylation of H3K27me3 by reducing Kdm6b expression. Accordingly, Kdm6b could be a promising marker for clinically predicting ART outcomes in patients with ovarian hyperstimulation syndrome.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Objective To explore the influence of heparin sodium on early recovery after lumbar surgery and the risk factors of deep vein thrombosis(DVT)of lower extremities,and build a prediction model for DVT after lumbar surgery based on the risk factors.Methods A total of 276 patients who underwent lumbar surgery and were treated with heparin sodium in The First Affiliated Hospital of Naval Medical University from January 2020 to January 2023 were selected as research objects.Activated partial thromboplastin time(APTT),prothrombin time(PT)and functional indexes of lumbar spine were recorded before and after treatment.DVT of lower extremities was detected by ultrasound during postoperative hospitalization,and then the patients were divided into DVT group and non-DVT group.The clinical data and laboratory indicators of all patients were collected.The risk factors of DVT after lumbar surgery were analyzed by logistic regression analysis.A postoperative DVT risk prediction model based on Logistic regression analysis was constructed and validated.Results APTT and PT after operation were higher than those before operation(P<0.05).The score of Oswestry Disability Index(ODI)3 months after surgery was lower than that before surgery(t=30.661,P<0.05).The incidence of DVT was 14.86%(41/276).Blood transfusion,bed rest≥5 d,proportion of general anesthesia,intraoperative blood loss,body mass index(BMI)and D-dimer level in the DVT group were higher than those in the non-DVT group(P<0.05).Logistic regression analysis showed that intraoperative blood loss,BMI,abnormal D-dimer level,intraoperative blood transfusion,and bed rest≥5 d were all risk factors for DVT after lumbar surgery(P<0.05).logit(P)=9.762+1.425×intraoperative blood loss+1.212×BMI+0.856×intraoperative blood transfusion+1.105×bed rest+1.671×D-dimer.Hosmer-Lemeshow test showed that the model had a high goodness of fit(χ2=4.025,P=0.473).The sensitivity,specificity and area under curve(AUC)of the constructed prediction model for postoperative DVT were 91.80%,70.40%and 0.836(95%CI:0.698-0.948),respectively.Conclusion Heparin sodium can improve blood circulation and lumbar function and prolong clotting time in patients with lumbar surgery.Intraoperative blood loss,BMI,abnormal D-dimer,intraoperative blood transfusion,and bed rest≥5 d are all risk factors for the occurrence of DVT after lumbar surgery.The prediction model based on the above risk factors has high predictive value for the occurrence of DVT after lumbar surgery.

Objective To explore the clinical effect of active risk prevention nursing on the prevention of skin injury in patients with esophageal cancer during radiotherapy.Methods A total of 102 patients who underwent radiotherapy for esophageal cancer in Jiangsu Cancer Hospital from December 2022 to November 2023 were enrolled.They were assigned to control group(n=51,routine nursing)and study group(n=51,routine nursing+active risk prevention)according to the random number table.The skin injury,quality of life,and nursing satisfaction were compared between the two groups.Results The skin injury in the study group at 20 Gy,40 Gy and at the end of radiotherapy was significantly slighter than that in the control group(P<0.05).After 4 weeks of intervention,the total score of SF-36 and scores in all dimensions in the study group were higher than those in the control group,and the degree of nursing satisfaction in the study group was significantly higher than that in the control group(72.55%vs 94.12%,χ2=8.541,P<0.05).Conclusion Active risk prevention can reduce skin injury,improve quality of life,and help to improve nursing satisfaction in patients with esophageal cancer during radiotherapy.

G protein-coupled receptor 120(GPR120)is one of the membrane receptors for long chain free fatty acids and is distributed in alveolus macrophages and airway epithelial Club cells.GPR120 activation alleviates the inflammation of respiratory tract,improves airway hyper-responsiveness,stimulates proliferation of Club cells and promotes the repair of respiratory epithelium,which may attenuate asthma and acute lung injury.

Objective To investigate the clinical features of myelin oligodendrocyte glycoprotein-IgG-associated disorders （MOGAD）. Methods A retrospective analysis was performed for the clinical data of nine patients with MOGAD who were admitted to our department. Results Among the nine patients with MOGAD， there were five male patients and four female patients， with a median age of onset of 29.0 years. The main clinical symptoms included optic neuritis in five patients， cerebral symptoms （including mental symptoms）in five patients，seizures in four patients， brainstem symptoms in three patients， pyramidal signs in three patients， cerebellar symptoms in three patients， rectal and bladder dysfunction in three patients， myelitis in two patients， paresthesia in two patients， and comorbidity with autoimmune encephalitis in one patient. All patients tested positive for serum MOG-IgG， and two patients tested positive for MOG-IgG in cerebrospinal fluid. MRI showed that cerebral lesions mainly involved the midline structure and deep gray matter，and there were four patients（44.4%） with lesions in the midbrain， the pons， and the medulla oblongata and four patients （44.4%）with lesions in the fourth ventricle； spinal lesions often involved long segments （≥3 segments）， and there were two patients with lesions in cervical spinal cord and one patient with lesions in the thoracic spinal cord. All nine patients received immunotherapy in the acute stage， with a mean Expanded Disability Status Scale score of （3.94±2.28） for neurological function assessment. Three patients experienced recurrence during the median follow-up time of 36.0 months，among whom two patients had myelitis. Conclusion There was no significant sex difference in the prevalence rate of MOGAD，and the age of onset of MOGAD is earlier than that of multiple sclerosis and neuromyelitis optica spectrum disorder.Optic neuritis is the most important clinical phenotype of MOGAD， and MOGAD patients with myelitis phenotype all have longitudinal long-segment lesions of the spinal cord. The different clinical phenotypes of MOGAD may be associated with recurrence rate.

Misophonia is a psychophysiological and behavioral disorder characterized by an individual's low tolerance to specific sounds， leading to intense negative emotional experiences and physiological responses. Currently， there is no standardized and universally effective treatment for misophonia in clinical practice worldwide. This article reports the case of an 18-year-old male patient with misophonia who showed poor response to sertraline combined with exposure and response prevention therapy. Subsequently， the patient received 8 weeks of Morita therapy （once a week， 50 minutes per session）， with symptomatic improvement. By presenting this case， we explore the potential efficacy of Morita therapy in treating misophonia， aiming to provide a reference for its clinical management. ［Funded by Scientific Research Development Fund Project of Shandong Second Medical University （number， 2024FYM034）］

Objective To assess the situation and influencing factors of occupational burnout among the staff at the Center for Disease Control and Prevention (CDC) in Sichuan Province. Methods A total of 1 038 CDC staff members in Sichuan Province were selected as the study subjects using the stratified random sampling method. Occupational burnout of the staff was assessed using the Maslach Burnout Inventory General Survey via an online questionnaire. Results The detection rate of occupational burnout was 42.3% (439/1 038). Binary logistic regression analysis result showed that, after controlling for confounding factors such as education level and alcohol consumption, CDC staffs aged at 20-<31, 31-<41, and 41-<51 years were at higher risk of occupational burnout compared with those ≥51 years (all P<0.05). CDC staffs with 5-<10 or ≥10 years of service had higher occupational burnout risk compared with those with <5 years (both P<0.05). CDC staffs with poor or fair health status, irregular diet, and poor sleep quality had higher risk of occupational burnout compared with those healthy, have regular diet, and good sleep quality (all P<0.05). The risk of occupational burnout increased with higher overtime frequency (all P<0.05). Conclusion Occupational burnout among CDC staffs in Sichuan Province is relatively high. Age, years of service, health status, diet, sleep quality, and overtime frequency are key influencing factors.
