Background/Aims: Liver transplantation is the most effective treatment for the sickest patients with acute-on-chronic liver failure (ACLF). However, the influence of donor age on liver transplantation, especially in ACLF patients, is still unclear. Methods: In this study, we used the data of the Scientific Registry of Transplant Recipients. We included patients with ACLF who received liver transplantation from January 1, 2007, to December 31, 2017, and the total number was 13,857. We allocated the ACLF recipients by age intogroup I (donor age ≤17 years, n=647); group II (donor age 18–59 years, n=11,423); and group III (donor age ≥60 years, n=1,787). Overall survival (OS), graft survival, and mortality were com-pared among the three age groups and the four ACLF grades. Cox regression was also analyzed. Results: The 1-, 3-, and 5-year OS rates were 89.6%, 85.5%, and 82.0% in group I; 89.4%, 83.4%, and 78.2% in group II; and 86.8%, 78.4%, and 71.4% in group III, respectively (p<0.001).When we analyzed the different effects of donor age on OS with different ACLF grades, in groupsII and III, we observed statistical differences. Finally, the cubic spline curve told us that the relative death rate changed linearly with increasing donor age. Conclusions Donor age is related to OS and graft survival of ACLF patients after transplanta-tion, and poorer results were associated with elderly donors. In addition, different donor ages have different effects on recipients with different ACLF grades.

Background Occupational stress is an important public health problem in the military. At present, there are few studies about occupational stress of officers and soldiers of the armed forces in China, especially the effects of plateau related environmental factors on occupational stress. Objective To understand current status and identify influencing factors of occupational stress among officers and soldiers stationed in plateaus, and provide a scientific basis for managing occupational stress. Methods In April 2023, stratified cluster sampling was used to recruit troops by deployed altitudes ranging from 500 to 3000 m into two strata of low altitude (＜2500 m) and high altitude (≥2500 m) based on the medical definition of plateau. Two regimental units were randomly selected from each stratum respectively, and one battalion unit was randomly selected from each regimental unit with all the officers and soldiers. Four selected battalion units were surveyed with a total of 2284 officers and soldiers. We designed a general questionnaire to collect their basic information, and distributed effort-reward imbalance questionnaires to evaluate occupational stress. We used logistic regression to identify potential influencing factors of occupational stress. Results Positive occupational stress was reported in 508 plateau-stationed officers and soldiers, with a prevalence rate of 22.2%. The total effort-reward imbalance score and the dimensional scores of effort, reward, and overcommitment in M (P₂₅, P₇₅) were 0.9 (0.7, 1.0), 16.0 (13.0, 19.0), 36.0 (33.0, 39.0), and 18.0 (15.0, 19.0), respectively. There were significant differences in the positive rate of occupational stress by gender, age, military service length, marital status, only child or not, physical fitness condition, reporting underlying diseases or not, exercise frequency before conscription, psychological changes after entering the plateaus, and having altitude sickness or not (P <0.05). The results of logistic regression showed that being female (OR=1.532, 95%CI: 1.061, 2.213), only child (OR=1.281, 95%CI: 1.038, 1.581), and with underlying diseases (OR=1.950, 95%CI: 1.340, 2.839) were associated with a higher risk of occupational stress. While setting 0 to <3 years of military service as the control group, the risk of occupational stress was higher in subgroups of 3 to 9 years (OR=1.380, 95%CI: 1.113, 1.710) and ≥9 years (OR=2.141, 95%CI: 1.461, 3.137). The participants reporting nervousness or fear (OR=1.728, 95%CI: 1.133, 2.635) and agitation or euphoria (OR=1.380, 95%CI: 1.113, 1.710) had a higher risk of reporting occupational stress than those with no psychological changes after entering the plateaus. Meanwhile, those who had regular exercise (OR=0.670, 95%CI: 0.492, 0.913) before enlistment, good physical fitness condition (OR=0.572, 95%CI: 0.426, 0.767) and excellent physical fitness condition (OR=0.502, 95%CI: 0.366, 0.688) had a lower risk of occupational stress. Conclusion Officers and soldiers in plateaus generally report a high rate of occupational stress. Female, military service length ≥3 years, being only child, with underlying diseases, nervousness/ fear or agitation/ euphoria after entering plateaus are risk factors for elevated occupational stress in this group; while good or excellent physical fitness condition and frequent exercise before enlistment are protective factors for occupational stress. Therefore, it is necessary to pay attention to the occupational stress problems in officers and soldiers stationed in plateaus and provide targeted intervention measures.

BACKGROUND:Inflammation is one of the important factors that induce cerebral ischemia-reperfusion injury.Studies have shown that electroacupuncture can effectively reduce inflammation after ischemic stroke and improve the symptoms of neurological deficits,but the mechanism is not clear. OBJECTIVE:To observe the effect of electroacupuncture on Toll-like receptor 4/nuclear factor-κB in rats with cerebral ischemia-reperfusion injury. METHODS:Forty-eight male Sprague-Dawley rats were randomly divided into sham operation group,model group and electroacupuncture group,with 16 rats in each group.The rat model of cerebral ischemia-reperfusion injury was prepared by middle cerebral artery occlusion.At 24 hours after modeling,the rats in the electroacupuncture group were treated with electroacupuncture,once a day,20 minutes each time,for a total of 5 days.The sham operation group and the model group did not do any intervention.After 5 days of intervention,Longa method was used to evaluate the degree of neurological injury in rats.Triphenyl tetrazolium chloride staining and hematoxylin-eosin staining were used to measure the volume of cerebral infarction and the pathological changes of brain tissue in rats.Serum interleukin-6,interleukin-18 and tumor necrosis factor-α were detected by ELISA.Expressions of Toll-like receptor 4 and nuclear factor-κB in the cerebral cortex at mRNA and protein levels were detected by fluorescence quantitative PCR and western blot,respectively. RESULTS AND CONCLUSION:Compared with the sham operation group,the neurological function scores,serum interleukin-6,interleukin-18,and tumor necrosis factor-α levels,Toll-like receptor 4 and nuclear factor-κB mRNA and protein expression levels were significantly higher in the model group(P＜0.01).Compared with the model group,electroacupuncture significantly reduced the neurological function scores,serum interleukin-6,interleukin-18,and tumor necrosis factor-α levels,Toll-like receptor 4 and nuclear factor-κB mRNA and protein expression levels(P＜0.05,P＜0.01).Compared with the sham operation group,the volume of cerebral infarction in the model group increased significantly(P＜0.01).Compared with the model group,the volume of cerebral infarction in the electroacupuncture group decreased(P＜0.05).In the model group,the arrangement of neurons was disordered,some nerve cells disappeared,nuclei presented with pyknosis and incomplete structure.After electroacupuncture intervention,the degree of neuronal degeneration and neuronal loss in the cerebral cortex of rats were reduced compared with those in the model group.To conclude,electroacupuncture can significantly improve the neurobehavior of rats with cerebral ischemia-reperfusion injury,reduce brain tissue injury,and effectively reduce the level of serum inflammatory factors.The mechanism may be related to the inhibition of Toll-like receptor 4/nuclear factor-κB signaling pathway.

Nowadays,the prevalence of nonalcoholic fatty liver disease(NAFLD)is constantly rising in China and globally,and its incidence rate is increasing year by year,which has seriously affected human life and health.Lipophagy is molecular chaperone-mediated autophagy and has the functions of promoting lipolysis,maintaining the lipid homeostasis of hepatocytes,and alleviating hepatocyte fatty degeneration.Lipophagy has three main processes of lipid droplet catabolism,lipid droplet autophagy,and fatty acid β-oxidation,which are regulated by key genes,receptors,and enzymes.Currently,important advances have been achieved for the intervention methods of traditional Chinese medicine,Western medicine,diet,and exercise in the research on lipophagy,which provides new perspectives for the prevention and treatment strategies for NAFLD.

Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

Objective To investigate the value of CT radiomics models based on intranodal and perinodal in distinguishing pulmonary cryptococcosis(PC)from lung adenocarcinoma.Methods A total of 194 patients,including PC(n=94)and lung adenocarcinoma(n=100),confirmed by surgical or puncture pathology were analyzed retrospectively and randomly divided into training set and test set in a ratio of 7∶3.3D Slicer was used to delineate and extract the intranodal and perinodal volume of interest(VOI)radiomics features within a 5 mm range.The minimum redundancy maximum relevance(mRMR)and least absolute shrinkage and selection operator(LASSO)methods were used to dimensionality reduction.Statistically significant indicators were screened by one-way logistic regression and further incorporated into the multifactor logistic regression model.Support vector machine(SVM)was used to construct the intranodal image-based radiomics model,the perinodal image-based radiomics model,the intranodal-and-perinodal image-based radiomics model,and the combined model.The diagnostic efficacy of each model was evaluated by receiver operating characteristic(ROC)curve.Results In the test set,the area under the curve(AUC)of the clinical imaging model,the intranodal image-based radiomics model,the perinodal image-based radiomics model,the intranodal-and-perinodal image-based radiomics model,and the combined model were 0.84,0.88,0.85,0.90,and 0.94,respectively.Conclusion The combined model based on clinical imaging features,intranodal and perinodal radiomics features can improve the ability of differentiating PC from lung adenocarcinoma.

A patient with osteomyelitis who developed a rash after previous treatment with vancomycin was admitted to the hospital due to a recurrence of osteomyelitis.After admission,the orthopedic doctor intended to perform a"calcium sulfate vancomycin implantation surgery"on him.Clinical pharmacist identified the patient's previous rash reaction as red man syndrome(RMS)rather than genuine drug allergy.At the same time,in response to the clinical doubt of whether patients with previous RMS can undergo"calcium sulfate vancomycin implantation surgery",clinical pharmacists reviewed and analyzed the literature,and suggested that the surgery can continue under close monitoring.The patient did not experience RMS or allergic reactions after surgery,and the condition improved.In this paper,the clinical pharmacists started with the identification of RMS and rapid allergic reactions,reviewed the literature on the local use of vancomycin and the risk of RMS,and provide suggestions for subsequent treatment,and also provide references for clinical safe drug use and treatment of similar diseases.
