Objective To comprehensively analyze the current epidemic characteristics and disease burden of brucellosis in Tongliao City, and to provide a basis for the prevention and control strategy of brucellosis in Tongliao City. Methods The report data of brucellosis in Tongliao City from 2018 to 2023 were collected. Descriptive methods were used for data analysis, and the disability-adjusted life years and indirect economic losses were calculated. Results From 2018 to 2023, a total of 22 034 cases were reported in Tongliao City, with an average annual incidence of 136.17/100 000. The incidence was statistically different between men and women ( χ²=12.23, P=0.032). The majority of cases were farmers (94.25%), followed by herdsmen (1.67%). The age group was concentrated between 30-60 years old (79.30%), among which the majority of cases were in the 40-50 years group (6 883/22 034). The onset time had seasonal characteristics, and the peak period was from March to August (the seasonal index was between 115.40%-151.29%). In terms of regional distribution, cases were reported in all counties (banners). The average annual incidence was highest in Kulun Banner (233.85/100 000) and Zalut Banner (210.13/100 000), and lowest in Keerqin District (42.28/100 000) and Holingol City (31.87/100 000). The analysis of disease burden showed that a total of 677.55 person-years (YLD) were lost from 2018 to 2023, with an average annual loss of 112.92 person-years. The total indirect economic loss was 59.3576 million yuan, with an average annual loss of 9.892 9 million yuan, and the people over 60 years old had the lowest annual loss. Conclusion The overall brucellosis epidemic in Tongliao City has shown a fluctuating downward trend. The epidemic prevention and control should be strengthened in farmers, people aged 40-50 years old, and areas such as Zalut Banner and Kulun Banner to further control the epidemic of brucellosis.

By reviewing the physical biological research on the activation of acupoint effects by acupuncture， this paper explains the activation mechanism from the perspective of the generation and transmission of mechanical signals caused by acupuncture， and reveals the physical-chemical coupling processes in the acupoint microenvironment. Future research should focus on locally mechanosensitive cells， further exploring how acupuncture mechanical signals trigger dynamic changes in cells and molecules in the acupoints， and the physical-chemical information transduction mechanism， which will provide scientific evidence for the acupoint activation during acupuncture. Related studies will contribute to a deeper understanding of the scientific principles behind acupuncture and promote its clinical application and development.

Endoscopic thoracic sympathicotomy/sympathotomy (ETS) is the first-line treatment for palmar hyperhidrosis with best minimally invasive effect. In recent years, with the widespread development of ETS in the treatment of palmar hyperhidrosis, many medical centers list ETS surgery as the day surgery. Nevertheless, there is no expert consensus on medical quality control of day surgery for ETS yet. Therefore, the Chinese Medical Doctor Association Thoracic Surgeons Branch Hyperhidrosis Subcommittee, Sympathetic Neurosurgery Expert Committee of WU Jieping Medical Foundation, and Fujian Provincial Strait Medical and Health Exchange Association Hyperhidrosis Special Committee organized domestic experts to conduct repeated consultations and sufficient discussions based on domestic and foreign literatures, to formulate the "Chinese expert consensus on ETS optimization and surgical quality control of day surgery for palmar hyperhidrosis". It aims to provide a reference for the clinical diagnosis and treatment of palmar hyperhidrosis for thoracic surgery colleagues in our country, to enhance their management level and work efficiency, and ultimately to achieve standardized quality control.

Background and purpose:The microphthalmia-associated transcription factor(MITF)plays a complex role in melanoma pathogenesis and progression.It is known to regulate multiple processes both in melanocytes and melanoma cells.While numerous studies have explored MITF in cutaneous melanoma(CM),research in acral melanoma(AM)is still limited.This study retrospectively analyzed the correlation between MITF expression and clinical,pathological characteristics and prognosis in AM patients,providing a basis for prognosis evaluation and personalized treatment plan formulation for patients.Methods:Patients who underwent primary resection of AM at Fudan University Shanghai Cancer Center from March 2008 to February 2022 were included.All surgical samples were diagnosed by clinical histopathology and used to construct the tissue microarray(TMA).This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(approval number:2203-ZZK-69-3).Cutting complete tissue microarray and evaluating MITF expression levels by immunohistochemistry(IHC)staining were carried out.The results were independently assessed and scored by three pathologists.Clinical and pathological data were collected from the hospital's electronic medical record system,and each patient's data was matched to their corresponding tissue sample on the chip.Patients were stratified into two groups based on MITF expression levels.Statistical analyses were performed to assess differences in clinical,pathological characteristics and survival outcomes between these two groups.Results:A total of 137 AM patients were included.MITF expression was significantly associated with T stage,N stage,American Joint Committee on Cancer(AJCC)stage,clark level,sentinel lymph node status,and presence of ulceration.Among these,N stage and ulceration were independent risk factors for high expression of MITF after adjusting for confounding factors.Survival analysis showed that AM patients with high MITF expression or higher T stage were associated with shorter disease-free survival(DFS).Patients with high MITF expression showed no significant difference in overall survival(OS)between observation or cytokine therapy and adjuvant immune checkpoint inhibitor(ICI)therapy,whereas those with low MITF expression derived significant survival benefits from ICI treatment.Conclusion:A higher N stage or the presence of ulceration indicates high MITF expression in tumor cells,with high MITF levels serving as a warning signal for early recurrence,metastasis,and even death.Patients with low MITF expression could receive improved OS with early adjuvant ICI therapy.MITF could not only serve as an auxiliary diagnostic marker for melanoma but also provide a basis for clinical prognosis assessment and the formulation of personalized treatment plans.

Background:The incidence and mortality rates of severe acute pancreatitis(SAP)have been increasing year by year.Therefore,early and rapid identification,along with timely intervention in the progression of acute pancreatitis(AP),is of particular importance.Aims:To explore the value of red blood cell distribution width(RDW)combined with BISAP score in the early prediction of SAP.Methods:A total of 561 AP patients admitted from January 2019 to December 2021 at the General Hospital of the Central Theater Command of the PLA were enrolled and divided into SAP group and non-SAP group according to the disease severity.Venous blood samples were collected within 24 hours of admission.The relevant clinical data,laboratory indices,BISAP score,and MCTSI score were compared between the two groups.Logistic regression analysis was used to identify the risk factors for SAP.Spearman correlation coefficient was employed to assess the correlation of these risk factors with the severity of AP,as well as the correlation of RDW with BISAP score and MCTSI score.The predictive values of these risk factors for SAP were evaluated by ROC curve analysis.Results:Compared with the non-SAP group,the prevalence of hypertension,length and cost of hospital stay,neutrophil count(NEUT),neutrophil-to-lymphocyte ratio(NLR),RDW,serum potassium,aspartate transaminase(AST),blood urea nitrogen(BUN),serum creatinine(SCr),BISAP score and MCTSI score were significantly increased in the SAP group(all P<0.05),while the lymphocyte count(LYM),serum calcium and albumin(ALB)were significantly decreased(all P<0.05).RDW(OR=1.582,95%CI:1.066-2.348,P=0.023),SCr(OR=1.018,95%CI:1.001-1.035,P=0.040),BISAP score(OR=6.210,95%CI:3.121-12.356,P<0.001),and MCTSI score(OR=2.917,95%CI:2.160-3.939,P<0.001)were the independent risk factors for SAP.RDW(rs=0.320,P<0.001),SCr(rs=0.103,P=0.015),BISAP score(rs=0.516,P<0.001),and MCTSI score(rs=0.512,P<0.001)were positively correlated with the severity of AP.Moreover,RDW was positively correlated with BISAP score(rs=0.428,P<0.001)and MCTSI score(rs=0.408,P<0.001).ROC curve analysis revealed that the areas under the ROC curve of RDW,SCr,BISAP score,MCTSI score,and combination of RDW and BISAP score for predicting SAP were 0.753,0.581,0.889,0.888,and 0.905,respectively.Conclusions:RDW,SCr,BISAP score,and MCTSI score are the independent risk factors for SAP.RDW combined with BISAP score can enhance the predictive value for SAP.

Background and Aims:Infected necrotizing pancreatitis(INP),particularly with diffuse distribution,is a life-threatening condition.The optimal initial intervention-minimally invasive step-up therapy vs.direct open necrosectomy-remains controversial.Moreover,the impact of necrosis morphology("wet"or"dry")and the presence of severe acute pancreatitis(SAP)on treatment selection has not been fully clarified.This study aimed to compare the efficacy and safety of these two approaches in diffuse INP and to evaluate the guiding value of CT-based necrosis type and SAP status in clinical decision-making.Methods:A retrospective analysis was conducted on 458 patients with diffuse INP admitted to the Third Xiangya Hospital of Central South University from January 2012 to March 2023.Patients were divided into a minimally invasive step-up group(n=256)and a direct open surgery group(n=202).SAP was defined according to the determinant-based classification,and necrosis was categorized as"wet"or"dry"based on CT features.The primary endpoint was a composite of death or major complications,while secondary endpoints included mortality,length of hospital stay,and incision-related complications,were compared between the two groups,with subgroup analyses performed accordingly.Results:Overall,the open surgery group had higher rates of the primary endpoint(62.4%vs.48.1%,P=0.003)and mortality(27.2%vs.16.8%,P=0.008)compared with the step-up group.Among SAP patients,the step-up approach resulted in a significantly lower primary endpoint rate(66.7%vs.97.7%,P=0.003).In non-SAP patients,the primary endpoint rates were similar,but open surgery was associated with a shorter hospital stay[(36.5±10.4)d vs.(45.6±18.6)d,P<0.001]and higher incidences of wound infection and incisional hernia(both P<0.001).Multivariate analysis identified infection onset time,effusion characteristics,gas bubbles,and necrosis location as independent predictors of prolonged hospitalization in the step-up group(all P<0.05).Patients with"wet"necrosis benefited more from the step-up approach,whereas those with"dry"necrosis experienced shorter hospitalization following open surgery.Conclusion:For diffusely distributed INP,treatment strategies should be individualized based on SAP status and necrosis liquefaction/imaging characteristics.The step-up minimally invasive approach is preferred for SAP patients and those with"wet"necrosis on CT,while direct open necrosectomy may be advantageous for"dry"necrosis(particularly with limited liquefaction)by shortening hospital stay and reducing certain major outcomes,though at the cost of increased incision infection and incision herina.CT imaging features and SAP classification can serve as valuable tools for risk stratification and guiding individualized timing and modality of intervention.

Objective:To investigate the effects of dagliprazin combined with olmesartan ester on the expression of Plin and miR-26a in renal tissues of diabetic nephropathy rats.Methods:Sixty male SD rats were selected and fed adaptively for 1 week, then fed high-fat and high-sugar diet for 2 months, and then injected streptozotocin (STZ) 30 mg/kg for modeling. They were given 10 mg/kg daaglizin intragastric administration as daglizin group, 10 mg/kg olmesartan ester intragastric administration as olmesartan ester group, 5 mg/kg daaglizin and 5 mg/kg olmesartan ester intragastric administration as daglizin and olmesartan ester combination group, respectively. Twenty rats were given 10 mg/kg normal saline intragastric administration as normal control group. After 3 months, the serum samples of rats were taken to detect the levels of fasting blood glucose, blood creatinine, urea nitrogen, 24h urinary microalbumin and other renal function indicators and the levels of C-reactive protein (CRP), tumor necrosis factor (TNF-α), cell surface specific marker antigen (ED-1) and other inflammatory responses. Then the rats were killed and their kidney tissues were taken. The protein and gene expression of vascular endothelial growth factor (VEGF), perilipin (Plin), Nephlrin, miR-26a were detected by Western blot and real-time fluorescence quantitative PCR.Results:The levels of fasting blood glucose, urea nitrogen, creatinine and 24h urinary microalbumin in dagliprazin group, olmesartan ester group and combined group were higher than those in normal control group ( P<0.05), while the levels of fasting blood glucose, urea nitrogen, creatinine and 24h urinary microalbumin in combined group were lower than those in dagliprazin group and olmesartan ester group ( P<0.05). The difference between groups was statistically significant ( P<0.05). The levels of serum CRP, TNF-αand ED-1 in dagliprazin group, olmesartan ester group and combined group were higher than those in normal control group ( P<0.05), while the levels of CRP, TNF-αand ED-1 in combined group were lower than those in dagliprazin group and olmesartan ester group ( P<0.05), and the differences between groups were statistically significant ( P<0.05). The expression of serum VEGF, Plin and Nephlrin protein in dagliprazin group, olmesartan ester group and combined group were lower than those in normal control group ( P<0.05), while the protein and gene of Plin and Nephlrin in combined group were lower than those in dagliprazin group and olmesartan ester group. The mRNA and protein expressions of miR-26a and VEGF were higher than those of Daglipzin group and olmesartan ester group ( P<0.05), and the differences between groups were statistically significant ( P<0.05) . Conclusion:Dagliprazin combined with olmesartan ester can reduce kidney injury and delay the progression of diabetic nephropathy by regulating the expression of Plin and miR-26a protein and gene in renal tissue of diabetic nephropathy rats.

Objective:Cognitive interviews were used to explore the target population's understanding and cognition of the Questionnaire about Gynaecological and Pelvic Pain Symptoms (ENDOPAIN-4D) in the Chinese context. The consistency of language expression and concept between the Chinese version ENDOPAIN-4D and the original scale was verified.Methods:Qualitative research methods were employed. Objective sampling method was used to select the patients with endometriosis/adenomyosis in the gynecological ward of Chinese Academy of Medical Sciences & Peking Union Medical College Hospital from October to December 2023 as the interview subjects. Two rounds of cognitive interviews were conducted, and the interview data were coded and analyzed using the Question Appraisal System. Based on the interview results and the recommendations of the expert group, the scale items were revised to form the Chinese version of ENDOPAIN-4D, and reliability and validity tests were conducted.Results:This study ultimately included 24 patients with endometriosis/adenomyosis, aged 24-47 years. The results of the first round of interviews showed that some interviewees had ambiguous understandings of the 16 items in the questionnaire, most of the item questions were concentrated in the category of "3 clarity, 4 hypotheses", and a small number of questions appeared in the category of "2 guidance, 5 knowledge/memory, 7 options", and were revised. The results of the second round of interviews showed that respondents could correctly understand the scale items. The Cronbach α coefficient of the total scale was 0.874, and the retest reliability was 0.952. The correlation coefficient of the Chinese version of the Global Pain Scale as the reference index of compatibility validity was 0.764 ( P<0.01), and the exploratory factor analysis extracted a total of 4 dimensions, with a cumulative variance contribution rate of 61.169%. The final formal questionnaire included 21 items in 4 dimensions including spontaneous pelvic pain, pain during sexual intercourse, intestinal pain and/or symptoms, and other symptoms. Conclusions:Cognitive interviews were used to identify cognitive biases in the target population during the completion of the scale and to address them appropriately, reducing the differences in the target population's understanding of the ENDOPAIN-4D scale and improving its scientific validity and reliability.
