Objective:To explore the clinicopathological characteristics and prognosis of fumarate hydratase-deficient uterine leiomyoma (FH-dUL).Methods:Clinical data and follow-up information for 117 patients with FH-dUL diagnosed through surgical pathology and immunohistochemistry in the First Affiliated Hospital of Nanjing Medical University from January 2020 to December 2024, were collected. A control group of 130 patients with common uterine leiomyomas was also included. The differences between the two groups in clinical, imaging, and pathological characteristics were compared. Additionally, recurrence rates, fertility outcomes for FH-dUL patients, and the incidence of renal cancer in FH germline mutation carriers were monitored.Results:(1) Comparison of clinicopathological characteristics: the median age of 117 FH-dUL patients was 35 years, and the median age at first diagnosis of uterine leiomyomas was 29 years, both significantly younger than the control group (41 and 36 years; both P<0.01). The FH-dUL group showed significantly higher incidences of uterine myomectomy, multiple leiomyomas, diffusion restriction on pelvic magnetic resonance imaging diffusion weighted imaging, and typical pathological features (candelabra-like vessels, bizarre nuclei, cytoplasmic eosinophilic globules, perinuclear halo, cellular atypia) and higher ultrasound blood flow score (all P<0.05). Of the 30 FH-dUL patients who underwent genetic testing, 9 had germline mutations, 3 had somatic mutations, and 6 had mutations of unclear origin. Among the 9 FH gene germline mutation patients, 2 had already developed renal cell carcinoma. (2) Recurrence analysis: among the 56 patients who underwent uterine myomectomy, 22 (39.3%, 22/56) experienced recurrence during follow-up, compared to 12 (21.8%, 12/55) of the 55 patients in the control group, the difference between the two groups was statistically significant ( P=0.046). Multivariate binary logistic regression analysis showed that cellular leiomyomas ( OR=9.489, 95% CI: 1.740-51.755; P=0.009) and multiple uterine leiomyomas ( OR=10.709, 95% CI: 1.354-84.683; P=0.025) were significant risk factors for recurrence in FH-dUL. (3) Fertility analysis: among the 66 FH-dUL patients who underwent fertility-preserving surgery, 16 had the intention to have fertility desire, only 2 (2/16) completed their fertility plans during follow-up. Conclusions:Clinicopathological features and imaging features help to differentiate FH-dUL from common type uterine fibroids, but lack specificity, and the diagnosis of FH-dUL is based on immunohistochemistry. The recurrence rate after resection of FH-dUL is high, and cellular and multiple leiomyomas are important predictors of recurrence. It is crucial to perform genetic testing, genetic counseling, drug treatment to prevent recurrence, fertility guidance, and long-term comprehensive management after surgery for FH-dUL management.

Objective:To characterize COVID-19-associated skin diseases and explore their influencing factors.Methods:A cross-sectional survey was conducted via the online platform Wenjuanxing in Changsha area from February 16, 2023, to March 16, 2023. The convenience sampling method was employed to conduct a survey of outpatients with a history of COVID-19 infection from the Second Affiliated Hospital of Hunan University of Chinese Medicine, as well as individuals in certain areas of Changsha who met the inclusion criteria for past COVID-19 infections. Demographic characteristics, COVID-19 infection details, and the occurrence of skin conditions after COVID-19 infection were collected. The chi-square test was used for inter-group comparisons of categorical data, and multivariate logistic regression analysis was performed to investigate factors associated with skin diseases following COVID-19 infection.Results:A total of 357 valid questionnaires were collected, and 357 patients with a history of COVID-19 infection were involved, including 246 females (68.9%) and 111 males (31.1%). Among these patients, 260 (72.8%) were aged ≤ 35 years. After COVID-19 infection, skin diseases occurred in 96 patients (26.9%), with urticaria (27 cases, 31.0%), rosacea (27 cases, 31.0%), hair loss (18 cases, 20.7%), and Henoch-Sch?nlein purpura (15 cases, 17.2%) being the most common diseases. Additionally, 96 patients (26.9%) had a history of pre-existing skin diseases, among whom 36 experienced exacerbation of their pre-existing skin diseases due to COVID-19 infection. Univariate analysis showed that gender, history of chronic diseases, history of allergic diseases, COVID-19 vaccination, duration of COVID-19 infection, and exacerbation of pre-existing skin diseases were significantly associated with the development of new skin diseases following COVID-19 infection (all P < 0.05). Multivariate logistic regression analysis revealed that gender (compared with females, males: OR = 0.235, 95% CI: 0.113, 0.490), history of allergic diseases (compared with patients without a history of allergic diseases, those with the history: OR = 2.159, 95% CI: 1.239, 3.761), and duration of COVID-19 infection (compared with the duration of < 5 days, duration of 6 - 7 days: OR = 3.043, 95% CI: 1.495, 6.193; duration of 8 - 14 days: OR = 2.364, 95% CI: 1.105, 5.506; duration of ≥ 15 days: OR = 4.406, 95% CI: 1.972, 9.849) were influencing factors for skin diseases after COVID-19 infection (all P < 0.05) . Conclusions:COVID-19 infection may lead to skin diseases such as urticaria, rosacea, hair loss, and Henoch-Sch?nlein purpura. Females, individuals with a history of allergic diseases, and those with a relatively long duration of COVID-19 infection were more prone to develop skin diseases after COVID-19 infection.

Clinically,neuroendocrine liver metastasis(NELM)is not uncommonly seen,which seriously affects the quality of life and prognosis of patients.For unresectable NELM,hepatic intra-arterial therapy is an effective option for controlling tumor progression and relieving symptoms.This therapy mainly includes transcatheter arterial embolization(TAE),transcatheter arterial chemoembolization(TACE),and selective internal radiotherapy(SIRT),and there was no significant difference in the long-term efficacy among the three therapies.Usually,TAE is recommended for patients with low-grade NELM.Conventional TACE may be considered for NELM patients who have poorly differentiated tumor or high hepatic tumor burden(HTB),and drug-eluting beads TACE is not recommended for NELM patients because it has significant hepatobiliary toxicity.SIRT can be adopted for NELM patients having portal vein thrombosis or having a history of biliary bowel surgery.In comprehensive treatment strategies for unresectable NELM,the combination use of hepatic intra-arterial interventional therapy and systemic therapy has already shown its promising prospects.Through reviewing the relevant literature,this paper summarizes the current situation and research progress of NELM.

Objective:The Self-Compassion Scale(SCS)is used to evaluate self-compassion in general popu-lation.The study was designed to evaluate the validity and reliability of the Chinese version of SCS in patients with eating disorders.Methods:Ten experts in the related disciplines completed the content validity evaluation.A total of 136 patients who met the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)eating dis-order diagnostic criteria were surveyed with SCS to evaluate structural validity.Using the Rosenberg Self-Esteem Scale(SES),Satisfaction with Life Scale(SWLS),and Eating Disorder Examination Questionnaire 6.0(EDE-Q 6.0)as gold criterion,the criterion validity of SCS was measured.Twenty patients were selected for retesting to e-valuate test-retest reliability.Results:The item-level content validity index(I-CVI)of each item was between 0.70 and 1.00,and the average scale-level content validity index(S-CVI/Ave)was 0.96,indicating good content validi-ty.Factor analysis indicated a good fit for the six-factor model with reasonable factor loadings:x2/df=1.70,RM-SEA=0.07,CFI=0.92,TLI=0.91.The Chinese version of the SCS had an ICC of 0.31 with both SES and SWLS,and a negative correlation with EDE-Q 6.0 scores(r=-0.32).The test-retest reliability of the scale was 0.80.Conclusion:The Chinese version of the SCS has moderate validity and high reliability in patients with eating disorders,and can provide a clinical measure tool for psychological assessment in the Chinese population with eating disorders.

Purpose To analyze the gene subtypes and characteristics of human papilloma virus(HPV)infection among women attending outpatient and physical examination centers at our hospital.Methods We utilized Polymerase Chain Reaction(PCR)combined with reverse dot hybridization to detect 28 HPV gene subtypes.Results HPV infection rate among the women was 24.15％.The five most prevalent high-risk(HR)and low-risk(LR)HPV gene subtypes were HPV 52,16,53,58,39,and HPV 61,81,54,42,44,respectively.Single and double infections accounted for 68.97％and 20.72％,with no signifi-cant difference found in the combination of multiple infection types.When stratified by age,the highest HPV infection rate was found among the group aged ≤25 years,followed by the group aged ≥66 years and then the group aged 56-65 years.This pattern of HPV infection rates across age groups revealed an approximate U-shaped curve.Conclusion The majority of female HPV in-fections in Huadu district are single infections,primarily affecting young and middle-aged women.HPV gene subtypes exhibit the characteristics of population or region-specific distribution.The overall infection rate of HPV is 24.15％,with the most common types being 52,16,and 53.The three peak age groups for HPV infection ranges are ≤25 years,56-65 years,and ≥66 years.

Objective:To investigate the epidemiological characteristics of pneumonia and the related factors of the length of hospitalization of pneumonia in the elderly aged 60 years and older in Ningbo in 2019.Methods:Data on hospitalized cases of pneumonia in the elderly aged 60 years and older in Ningbo in 2019 were collected through the regional health information platform, and the population data of Ningbo in 2019 were obtained through the Zhejiang Provincial Bureau of Statistics. A descriptive epidemiological analysis was conducted on hospitalized cases of pneumonia in the elderly population, and factors related to the length of hospitalization were explored.Results:A total of 15 956 hospitalized cases of pneumonia aged 60 years and older were reported in Ningbo in 2019, and the incidence of pneumonia requiring hospitalization was 1.02% (15 956/1 571 431). The incidence was 1.13% (8 613/760 357) in males and 0.83% (6 759/811 074) in females, and the ratio of male to female cases was 1.27∶1. The highest incidence was found in the ≥80 age group (2.52%), and the lowest incidence was found in the 60-69 age group (0.58%). March, February, and January were the peak period of pneumonia hospitalization. The main types of pneumonia diagnosed were not specified (65.12%), followed by bacterial pneumonia (34.60%). The M( Q1, Q3) of hospitalized patients with pneumonia was 9 (7, 13) days. The results of multivariate logistic regression analysis showed that gender (female: OR=0.911, 95% CI: 0.849-0.978) and older age (70-79 years old: OR=1.211, 95% CI: 1.111-1.321; ≥80 years old group: OR=1.486, 95% CI: 1.365-1.617), settlement method (self-payment: OR=0.567, 95% CI: 0.464-0.691), higher level of hospitals (Grade Ⅱ: OR=1.902,95% CI:1.723-2.100; Grade Ⅲ: OR=1.546,95% CI:1.407-1.698) were associated with the length of hospitalization for pneumonia in people aged 60 years and older in Ningbo. Conclusions:Hospitalization with pneumonia in people aged 60 years and older was high in winter and spring, men and older adults were in high-risk groups in Ningbo in 2019. Gender, age, billing method, and level of hospitals may be related factors to the length of hospitalization for pneumonia.

The incidence rate of aortic dissection (AD) is low, but it is highly fatal in the acute phase. Miss diagnosis and misdiagnosis can occur occasionally, resulting the miss of the best intervention time. Research on the epidemiological characteristics and of AD and related risk factors can identify high-risk groups, make screening and diagnosis as soon as possible and effectively control the changeable risk factors to reduce the incidence of AD and improve the outcome of AD cases. This paper summarizes the progress in research of the epidemiological characteristics of AD and related risk factors in order to promote early prevention and diagnosis of AD, improve the AD case management and intervention level.

Abstract Falls are the leading cause of accidental injury deaths among the elderly. Currently, the incidence and disease burden of falls among the elderly remain high. By understanding the influencing factors of falls among the elderly and formulating targeted preventive measures, the risk of falls can be effectively reduced. Studies have found that falls among the elderly are results of the interaction of multiple factors. When formulating fall prevention strategies, attention should be paid to fall risk assessment and stratification, fall prevention exercise support and health education, living environment improvement, and primary healthcare service enhancement. Reviewing publications pertaining to the epidemiological studies of falls from January 2004 to January 2024, this article summarizes the epidemiological characteristics, risk factors, prevention and control strategies of falls among the elderly, aiming to provide the reference for prevention and control.
