Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2012 to 2024, and to provide a scientific basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the incidence data of mumps in Guangxi from 2012 to 2024. Results A total of 159 873 mumps cases were reported from 2012 to 2024 in Guangxi, with an average annual reported incidence of 25.41/100 000, and no death. Mumps occurred every month, with the peak incidence mainly concentrated in April to July and October to January of the next year. There were 96,118 male cases (29.43 /100 000), and 63 755 female cases (21.07 /100 000). The male to female ratio was 1.40:1, and the difference between male and female was significant (χ²=4 321.276，P＜0.05). The annual incidence of mumps showed a certain periodic change, with the incidence peak and trough alternating every 4 - 5 years. The majority of patients were under 15 years old, accounting for 85.32% of the total number of cases. The patients mainly included students, preschool children and scattered children. The highest average incidence was in Nanning City with 40 231 cases (42.08/100 000), and the lowest was in Qinzhou City with 3 466 cases (8.16/100 000). From 2012 to 2024, a total of 210 mumps outbreaks with 4 483 cases were reported in Guangxi. Conclusion The incidence of mumps in Guangxi from 2012 to 2024 shows a periodic change and obvious seasonality. People under 15 years old are the key group at risk of mumps. The prevention and control of the epidemic of mumps in schools and kindergartens should be strengthened. It is suggested to carry out long-term monitoring of mumps as well as immune effect research, and continue to maintain a high vaccination rate of 2 doses of mumps-containing vaccines.

Objective: To investigate the association of primary tumor site with prognosis in vulvar cancer, stratified by vulvar squamous cell carcinoma (SCC) and non-SCC histological types. Methods: This population-based retrospective study enrolled patients with vulvar cancer from the Surveillance, Epidemiology, and End Results database between January 2000 and December 2018. The primary outcome was cancer-specific survival (CSS). The prognostic difference between labium majus, labium minus and clitoris groups was investigated using Kaplan–Meier analyses and Cox proportional hazards regression analyses. Results: A total of 3,465 eligible patients with vulvar cancer were included with a mean age of 54.5 years. Among the 1,076 (31.1%) patients with non-SCC, the multivariate Cox regression analyses showed that labium minus-sited disease (hazard ratio [HR]=1.85; 95% confidence interval [CI]=1.27–2.71; p=0.001) and clitoris-sited disease (HR=2.37; 95% CI=1.47–3.85;p<0.001) were significantly associated with worse CSS, compared with labium majus-sited disease. However, among the 2,389 (68.9%) patients with SCC, no significant association of primary tumor site with CSS was found (p>0.05). Kaplan–Meier analyses also showed that the primary tumor site had a significant prognostic effect in vulvar non-SCC (p<0.001) but not in vulvar SCC (p=0.330). Conclusion Among vulvar non-SCC, patients with labium minus-sited disease had a significantly worse prognosis than those with labium majus-sited disease, and a significantly better prognosis than those with clitoris-sited disease. Gynecologic oncologists should consider the prognostic effect of primary tumor site in vulvar non-SCC, and make optimal, personalized treatment and surveillance strategies based on different primary tumor sites.

Aim To investigate the relationship between systemic inflammatory immune index(SII)and systemic inflammatory response index(SIRI)and the risk of in-hospital major adverse cardiovascular events(MACE)in patients with acute myocardial infarction(AMI).Methods Retrospective analysis was conducted on AMI patients ad-mitted to the Second Cardiovascular Disease Area of Suining Central Hospital from February 2021 to May 2022.Based on inclusion and exclusion criteria,246 patients were finally enrolled.According to whether MACE occurred during hospital-ization,they were divided into event group and non-event group,and baseline data of the two groups were compared.All variables except SII and SIRI were included in a univariate-multivariate Logistic regression analysis to screen factors af-fecting the risk of MACE,and were used as significant covariates for adjustment to evaluate the relationship between SII and SIRI and the risk of MACE respectively.Results The results of multivariate Logistic regression analysis showed that emergency PCI,left ventricular ejection fraction,albumin level and age were significant factors affecting the risk of in-hos-pital MACE in AMI patients(OR=0.432,95％CI:0.194～0.960,P=0.038;OR=0.930,95％CI:0.890～0.969,P=0.001;OR=0.730,95％CI:0.621～0.845,P＜0.001;OR=1.143,95％CI:1.070～1.228,P＜0.001),and a basic model was established based on this.After adjusting for the significant covariates,SII and SIRI were both independ-ent risk factors for in-hospital MACE(OR=1.004,95％CI:1.001～1.008,P=0.002;OR=4.467,95％CI:2.597～8.142,P＜0.001).The areas under the curves of SII and SIRI were 0.658 and 0.785,respectively,and the optimal cutoff values were 434.83 and 1.03.Restricted cubic spline analysis showed that SII(Nonlinear P=0.639)and SIRI(Nonlinear P=0.683)were linearly related to the risk of MACE after adjusting significant covariates.Threshold effect a-nalysis showed that when SIRI＞0.93,the risk of MACE began to increase.Conclusion Elevated levels of SII and SI-RI are independent risk predictors for the occurrence of in-hospital MACE in AMI patients.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

BackgroundPatients with schizophrenia and depressive disorders exhibit abnormalities in perceptual processing. Previous perceptual studies are mainly based on asking participants to fill in a questionnaire， and little research has been undertaken on objective behavior in patients with schizophrenia and depressive disorders. ObjectiveTo explore the behavioral changes in vibrotactile sense among patients with schizophrenia and depressive disorders， so as to enrich relevant findings in objective behavioral research. MethodsFrom March 2021 to September 2023， 33 patients with schizophrenia and 31 patients with depressive disorders in the outpatient and inpatient departments of Beijing Huilongguan Hospital and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria were enrolled. And another 34 healthy controls were concurrently recruited at Beihang University and Beijing Huilongguan Hospital. Patients with schizophrenia were assessed using Positive and Negative Symptom Scale （PANSS）， and patients with depressive disorders were assessed using Hamilton Depression Scale-17 item （HAMD-17）. The vibrotactile sensitivity of the left hand in all participants was tested in a delay match-to-sample procedure， and the correct rate of vibrotactile delayed discrimination task was compared among the three groups. ResultsCompared with healthy controls， a reduction was found in the correct rates at index finger， middle finger and ring finger in patients with schizophrenia （P<0.01）， the average correct rate at five fingers in patients with schizophrenia （P=0.001）， and the correct rate at thumb in patients with depressive disorders （P=0.026）. No statistical difference was reported in correct rate of vibrotactile delayed discrimination task between patients with depression disorders and schizophrenia （P>0.05）. The average correct rate of vibrotactile sense in schizophrenia group was not significantly correlated with the duration of disease， age of onset， chlorpromazine equivalent doses and PANSS score （r=0.058、0.045、0.114、-0.194， P>0.05）. The average correct rate in depressive group was negatively correlated with age of onset （r=-0.415， P=0.020）， but not significantly correlated with the duration of disease and HAMD-17 score （r=-0.044， 0.142， P>0.05）. ConclusionPatients with schizophrenia and depressive disorders have impaired vibrotactile sense. The vibrotactile sense is impaired in index， middle and ring fingers among patients with schizophrenia， and in thumbs of patients with depressive disorders. Moreover， the impairment in patients with depressive disorders may be related to the age of onset. ［Funded by 2023 Hebei Provincial Graduate Innovation Funding Project （number， CXZZSS2023140）］

Objective Pertussis cases have increased markedly since 2018 in Guangxi.The aim of this study was to evaluate antibody levels and the infection status of pertussis in the resident population. Method A total of 10,215 serum samples from residents were collected from August-November 2018 and tested for anti-pertussis IgG and toxin IgG using the enzyme-linked immunosorbent assay(ELISA). Results Of the collected samples,1,833(17.94%)tested positive for anti-pertussis IgG,with the median concentration of 16.06 IU/mL.Antibody level<10 IU/mL accounted for more than 60%in children under 4 years of age,but declined with age,whereas the percentages of the other three levels(10-40,40-50,and≥50 IU/mL)increased almost with age(P<0.001).Moreover,7,924 samples were selected for anti-pertussis toxin IgG,of which 653(8.24%)tested positive(≥40 IU/mL)with the median concentration of 5.89 IU/mL,and 204 participants(2.56%)had recent pertussis infection(≥100 IU/mL).Among the different age groups,the highest rates of positivity and recent infection were observed at 11-20 years of age,the lowest positivity rate at 5 years of age,and the lowest recent infection rate at 4 years of age(P<0.001,P=0.005,respectively). Conclusion The survey results showed that all age groups in Guangxi lacked immunity against pertussis,which was one of the main factors contributing to the resurgence of pertussis in 2018.In addition,the prevalence of pertussis is relatively high in Guangxi,and its incidence is seriously underestimated,especially in adolescents and adults.

The efficient clinical treatment of oral squamous cell carcinoma(OSCC)is still a challenge that demands the development of effective new drugs.Phenformin has been shown to produce more potent anti-tumor activities than metformin on different tumors,however,not much is known about the influence of phenformin on OSCC cells.We found that phenformin suppresses OSCC cell proliferation,and promotes OSCC cell autophagy and apoptosis to significantly inhibit OSCC cell growth both in vivo and in vitro.RNA-seq analysis revealed that autophagy pathways were the main targets of phenformin and identified two new targets DDIT4(DNA damage inducible transcript 4)and NIBAN1(niban apoptosis regulator 1).We found that phenformin significantly induces the expression of both DDIT4 and NIBAN1 to promote OSCC autophagy.Further,the enhanced expression of DDIT4 and NIBAN1 elicited by phenformin was not blocked by the knockdown of AMPK but was suppressed by the knockdown of transcription factor ATF4(activation transcription factor 4),which was induced by phenformin treatment in OSCC cells.Mechanistically,these results revealed that phenformin triggers endoplasmic reticulum(ER)stress to activate PERK(protein kinase R-like ER kinase),which phosphorylates the transitional initial factor eIF2,and the increased phosphorylation of eIF2 leads to the increased translation of ATF4.In summary,we discovered that phenformin induces its new targets DDIT4 and especially NIBAN1 to promote autophagic and apoptotic cell death to suppress OSCC cell growth.Our study supports the potential clinical utility of phenformin for OSCC treatment in the future.
