Objective To explore the prevalence of depressive symptoms in postoperative patients with ovarian cancer and to analyze its influencing factors from multiple dimensions, including clinical characteristics, psychological factors, and laboratory indicators. Methods A cross-sectional study was conducted, which enrolled 235 postoperative patients with ovarian cancer. Depressive status was assessed using the patient health questionnaire, and the demographic, pathological, and medical record data of the patients were collected using the generalized anxiety disorder scale, Pittsburgh sleep quality index, European organization for research and treatment of cancer quality of life questionnaire core 30, and ECOG performance status score. Peripheral blood tumor marker (CA125), routine blood test, lymphocyte subsets, and serum cytokine levels were measured. Univariate and multivariate binary logistic regression analysis were used for statistical analysis. Results The prevalence of depression in postoperative patients with ovarian cancer was 39.15% (92/235). Univariate analysis showed that ECOG score ≥ 2 points, pain, anxiety, poor sleep quality, low quality of life, low life satisfaction, tumor recurrence, six or more cycles of chemotherapy, as well as higher levels of CA125, NLR, and NAR, and lower hemoglobin levels were significantly associated with depression (all P<0.05). Multivariate binary Logistic regression analysis showed that anxiety (OR=1.975, 95%CI: 1.231-3.170), sleep efficiency (OR=4.181, 95%CI: 1.211-14.43), sleep latency (OR=34.806, 95%CI: 4.258-284.542), ECOG performance status score, cognitive function (OR=0.918, 95%CI: 0.868-0.97), and life satisfaction were independent risk factors for depression (all P<0.05). Laboratory indicators were not independent influencing factors in the multivariate Logistic regression model. Conclusion Depression in postoperative patients with ovarian cancer is influenced by physiological, psychological, and social factors. Clinical management should focus on patients with anxiety, sleep disorders, poor physical condition, and low life satisfaction, and a comprehensive prevention and treatment strategy centered on psychological intervention and taking into account symptom management and social support should be implemented.

Objective: To investigate the awareness of knowledge about hepatitis C prevention and control among outpatients in Ningbo City, Zhejiang Province, and its influencing factors, so as to provide the evidence for strengthening health education on hepatitis C prevention and control. Methods: Based on sentinel surveillance of hepatitis C, the outpatients aged 15 to 65 years at seven hospitals in Yinzhou District, Cixi City and Xiangshan County of Ningbo City were selected using the convenient sampling method from April to June during 2020 and 2022. Demographic information, knowledge and behaviors related to hepatitis C prevention and control were collected through questionnaire surveys. The influencing factors for knowledge about hepatitis C prevention and control were analyzed using a multivariable logistic regression model. Results: A total of 2 792 participants were surveyed, including 1 157 males (41.44%) and 1 635 females (58.56%). The awareness rate of knowledge about hepatitis C prevention and control was 56.23%, and was lower in knowledge about hepatitis C vaccine and treatment. The awareness rates of knowledge about hepatitis C prevention and control among outpatients from 2020 to 2022 were 47.11%, 53.22% and 70.65%, respectively, showing an upward trend (P<0.05). Multivariable logistic regression analysis showed that participants aged 25 to <50 years (OR=1.358, 95%CI: 1.073-1.719), with an educational level of high school or junior college (OR=1.431, 95%CI: 1.134-1.806) or above junior college (OR=3.728, 95%CI: 2.958-4.699), with household monthly income per capita of 3 000 to <5 000 yuan (OR=1.828, 95%CI: 1.344-2.486) or ≥5 000 yuan (OR=1.858, 95%CI: 1.366-2.526), without a history of invasive treatments such as pedicure in public places (OR=1.287, 95%CI: 1.024-1.618), without a history of contact with family members' blood-contaminated items (OR=2.050, 95%CI: 1.552-2.707), and always using condoms during sexual contacts (OR=1.740, 95%CI: 1.273-2.378) had higher awareness of knowledge about hepatitis C prevention and control. Conclusions The awareness of knowledge about hepatitis C vaccine and treatment among outpatients in Ningbo City needs to be improved. Age, educational level, household monthly income per capita, history of invasive treatments such as pedicure in public places, history of contact with family members' blood-contaminated items and frequency of condom use during sexual contacts are associated with outpatients' awareness of knowledge about hepatitis C prevention and control.

Immunotherapy for cancer,as an emerging treatment modality,has made significant strides in recent years and has become a crucial therapeutic approach following surgery,radiotherapy,chemotherapy,and targeted therapy.In particular,the clinical utilization of immune checkpoint inhibitors(ICIs)has not only enhanced the survival rates of patients with refractory or recurrent tumors but has also significantly optimized the overall strategy for cancer treatment.However,as the population undergoing cancer immunotherapy continues to grow,this expansion not only yields clinical benefits but also precipitates a range of specific adverse reactions known as immune-related adverse events(irAEs).Pleural effusion is a common and severe complication in cancer patients,significantly affecting both their quality of life and treatment outcomes.Typically,tumor-related pleural effusion is often due to pleural metastasis,with malignant pleural effusion(MPE)characterized by rapid growth,being difficult to control,and tendency for recurrence.With the approval of new drugs and the expansion of indications for existing medications,the number of cancer patients receiving ICIs treatment is increasing,bringing ICIs-related pleural effusion into focus.While ICIs treatment-related pleural effusion is relatively rare in clinical practice,it is closely linked to treatment choices of patients and prognosis.Unlike MPE,the pathogenesis of ICIs treatment-related pleural effusion is more complex,not only involving non-specific immune activation leading to autoimmune inflammatory reactions but also potentially related to nodular pleural granulomatous reactions,eosinophilic chronic pleurisy,and tumor-infiltrating lymphocytes.In terms of diagnosis,ICIs treatment-related pleural effusion is typically diagnosed through exclusion,requiring the exclusion of other causes such as tumor progression,radiotherapy,and chemotherapy-induced pleural effusion,adding complexity and difficulty to the diagnostic process.Treatment for ICIs treatment-related pleural effusion often involves glucocorticoids,tocilizumab,or infliximab,aiming to alleviate symptoms and improve prognosis by suppressing excessive immune reactions.Preventing the occurrence of ICIs treatment-related pleural effusion is equally crucial,necessitating comprehensive patient assessment before ICIs administration and continuous monitoring during treatment to promptly detect and manage potential adverse reactions.Through this comprehensive management approach,the impact of ICIs treatment-related pleural effusion on patient quality of life and treatment outcomes can be minimized,optimizing overall treatment results.This review aimed to explore the pathogenesis,histological features,clinical manifestations,diagnostic methods and treatment strategies of ICIs treatment-related pleural effusion,and delve into the characteristics of ICIs treatment-related pleural effusion,in order to enhance understanding of this complication and provide a reference for clinical practice.

Objective To explore the efficacy of a model combining clinicopathological characteristics and multiparametric MRI features for predicting BRCA-mutated breast cancer(BC).Methods A total of 256 BC patients were retrospectively selected and divided into BRCA mutation group(116 cases)and BRCA wild group(140 cases)based on the BRCA results.Chi-square tests or independ-ent sample t-tests were used to compare the differences in clinicopathological characteristics and multiparametric MRI features between the BRCA mutation group and the wild group.Risk factors for BRCA-mutated BC were identified through univariate and multivariate logistic regression ananlyses,and a combined predictive model was constructed.Receiver operating characteristic(ROC)curve was used to ana-lyze the diagnostic efficacy of the model.Results There were statistically significant differences in T stage,human epidermal growth factor receptor 2(HER-2),Ki-67,non-mass enhancement,enhancement pattern,time-signal intensity curve(TIC)type,and apparent diffusion coefficient(ADC)values between the BRCA mutation group and the wild group.Univariate logistic regression analysis showed that T stage,HER-2,Ki-67,non-mass enhancement,enhancement pattern,TIC type,and ADC values were risk factors for BRCA-mutated BC(P<0.05).Multivariate logistic regression analysis revealed that T stage,HER-2,Ki-67,enhancement pattern,and TIC type were independent risk factors for BRCA-mutated BC(P<0.05).The combined model incorporating T stage,HER-2,Ki-67,enhancement pattern,and TIC type had the best diagnostic efficacy in predicting BRCA-mutated BC,with an area under the curve(AUC)of 0.751.Conclusion The combined model integrating T stage,HER-2,Ki-67,enhancement pattern,and TIC type has good efficacy in predicting BRCA-mutated BC.

Objective To establish and validate the reference interval for serum anti-Müllerian hormone(AMH)in healthy women of childbearing age in Shenzhen using an indirect method based on mathematical statistics.Methods Collected the AMH data for women aged 21～50 in outpatient and physical examination populations in Shenzhen Maternity and Child Health Care Hospital from 2017 to 2023.Grouping by age range of five,first performed normality tested on each group of data,and used the interquartile range method to remove outliers for non-normal data.Then established reference intervals for AMH in different age groups through indirect method(Hoffmann method)and verified them.Compared with the reference interval of the reagent instructions and analyzed the correlation be-tween serum AMH levels and age.Results The correlation coefficient between serum AMH and age in women of childbearing age was-0.642,and the difference was statistically significant(P<0.001).The distribution of AMH levels among women in six age groups was compared,and the difference was statistically significant(H=28 392.655,P<0.05),and AMH levels showed a decreasing trend with age.The reference range of serum AMH at ages 21～25,26～30,31～35,36～40,41～45 and 46～50 yesrs were 0.92～11.30,0.68～9.43,0.38～7.51,0.12～6.93,<4.42 and<1.83ng/ml,respectively,and all reference intervals in each group had been validated.Compared to the age groups provided by the manufacturer,the age groups in this study are more refined,the reference range was narrower,and the interpretation of clinical and laboratory data was more accurate.Conclusion This study used Hoffmann's indirect method for the first time to establish a reference range for AMH in women aged 21～50 years in Shenzhen.The reference interval established is more in line with the actual situation and is a simple and reliable acquisition mode,suitable for promotion and wide application in clinical labo-ratories.

Objective:To investigate the relationship between terminal soft tissue infection of the diabetic foot and glucose and lipid metabolism as well as inflammatory factors.Methods:A total of 126 patients with diabetes mellitus combined with foot-soft tissue infections, who hospitalized in our hospital from March 2018 to February 2023 were divided into mild group (46 cases), moderate group (43 cases) and severe infections group (37 cases) according to the degree of foot-soft tissue infection before treatment. The glucose and lipid metabolism and inflammatory factors of patients among the different groups were compared, and the effects of glycolysis and lipid metabolism and inflammatory factors on the soft tissue infection at the end of diabetic foot were analyzed by logistic regression analysis. Patients were treated with antimicrobial therapy and other treatments. After 2 weeks of anti-infective treatment, if three consecutive cultures of secretions were negative for bacteria, antibiotic therapy was discontinued and glucose-lipid metabolism and inflammatory factors after treatment were compared. Patients were followed up for 1 year, and the changes in glucose-lipid metabolism and inflammatory factors were observed in toe or limb amputations group ( n=38) and non-toe or limb amputations group ( n=88). Results:Before treatment, the levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), free fatty acids (FFA), fasting plasma glucose (FPG), fasting insulin (FINS), glycosylated hemoglobin typeA1c (HbA 1c), vascular cell adhesion molecule-1 (VCAM-1), C reactive protein (CRP,) tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) in the mild group were significantly lower than those in the moderate and severe group, and the adiponectin (APN) level was significantly higher than that in the moderate and severe group (all P<0.05). Logistic regression analysis showed that FFA, FPG, FINS, APN, VCAM-1, CRP, TNF-α and IL-6 were risk factors of terminal soft tissue infection ( P<0.05). After treatment, the levels of TC, LDL-C, FFA, FPG, FINS, HbA1c, VCAM-1, CRP, TNF-α and IL-6 were significantly decreased, and the APN was significantly increased (all P<0.05). The levels of TC, LDL-C, FFA, FPG, FINS, HbA1c, VCAM-1, CRP, TNF-α, and IL-6 were significantly higher in the toe/limb amputation group than in the non-toe/limb amputation group, and the APN levels were significantly lower in the toe/limb amputation group than in the non-toe/limb amputation group (all P<0.05). Conclusion:There is a close relationship between glucose and lipid metabolism, inflammatory factors and terminal soft tissue infection of the diabetic foot.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

OBJECTIVE To develop a mobile intelligent pharmacy management assistant system （abbreviated as “assistant system”）， thus providing convenient support for the daily operational management of pharmacies. METHODS The system was developed using the WeChat developer tools with WXML， WXSS， and JavaScript based on the platform as a service （PaaS）. Test users were recruited， and in five different scenarios， namely pharmaceutical knowledge inquiry， drug damage registration， medication error data analysis， drug expiration date registration， and duty handover， the task execution time was recorded for both the new （assistant system） and old （paper-based records and fixed computer records） modes. Additionally， users’ opinions on the advantages of the new mode were collected. RESULTS The assistant system comprised six modules: shift handover， pharmaceutical knowledge database， medication error registration， drug expiry management， drug damage registration， and medication consultation records. Among 10 test users， in all scenarios except for the shift handover record， the task execution time under the new mode was shorter than that under the old mode （P＜0.05）. Most test pharmacists highlighted that the primary advantages of the new mode lie in its iterative flexibility， and ease of use among other benefits. CONCLUSIONS The assistant system based on PaaS cloud model WeChat mini program developed in this study can significantly improve the daily management efficiency of the pharmacy and optimize the task execution experience for pharmacists.

Objective To investigate the efficacy of leaflet augmentation technique to repair the recurrent mitral valve (MV) regurgitation after mitral repair in children. Methods A retrospective analysis was conducted on the clinical data of children who underwent redo MV repair for recurrent regurgitation after initial MV repair, using a leaflet augmentation technique combined with a standardized repair strategy at Fuwai Hospital, Chinese Academy of Medical Sciences, from 2018 to 2022. The pathological features of the MV, key intraoperative procedures, and short- to mid-term follow-up outcomes were analyzed. Results A total of 24 patients (12 male, 12 female) were included, with a median age of 37.6 (range, 16.5–120.0) months. The mean interval from the initial surgery was (24.9±17.0) months. All children had severe mitral regurgitation preoperatively. The cardiopulmonary bypass time was (150.1±49.5) min, and the aortic cross-clamp time was (94.0±24.2) min. There were no early postoperative deaths. During a mean follow-up of (20.3±9.1) months, 3 (12.5%) patients developed moderate or severe mitral regurgitation (2 severe, 1 moderate). One (4.2%) patient died during follow-up, and one (4.2%) patient underwent a second MV reoperation. The left ventricular end-diastolic diameter was significantly reduced postoperatively compared to preoperatively [ (43.5±8.6) mm vs. (35.8±7.8)mm, P<0.001]. Conclusion The leaflet augmentation technique combined with a standardized repair strategy can achieve satisfactory short- to mid-term outcomes for the redo mitral repair after previous MV repair. It can be considered a safe and feasible technical option for cases with complex valvular lesions and severe pathological changes.
