Objective To explore the mediating effect of sleep quality between somatic symptoms and severity of depression in patients with depression. Methods A total of 384 drug-naive patients diagnosed with depression were recruited from the Department of Psychological Medicine of Zhongshan Hospital, Fudan University, during the period from February to August 2024. The severity of depression, somatic symptoms, and sleep quality were assessed using Patient Health Qusetionaire (PHQ)-9, PHQ-15, and Pittsburgh sleep quality index (PSQI), respectively. Based on the PHQ-15 scores, all participants were stratified into two groups: a mild somatic symptoms group（＜10 points, n＝136）and a moderate-to-severe somatic symptoms group（≥10 points, n＝248）. Comparisons of sleep quality between the two groups were conducted, and partial correlation analysis was performed to examine the correlation between sleep quality and somatic symptoms. Additionally, linear regression and mediation analyses were conducted to investigate the mediating effect of sleep quality between somatic symptoms and severity of depression. Results The PSQI scores in moderate-to-severe somatic symptoms group were significantly higher than those in mild somatic symptoms group (P＜0.001). Partial correlation analysis indicated that, after controlling for depression severity, the positive correlation between PSQI and PHQ-15 scores remained significant in both groups (P＜0.01). Regression analysis identified both sleep quality and somatic symptoms as predictors of severity of depression (P＜0.001). Additionally, mediation analysis demonstrated that sleep quality partially mediated the relationship between somatic symptoms and severity of depression, accounting for 26.63% (0.090/0.338) of the total effect. Conclusions In patients with depression, sleep quality is associated with somatic symptoms, and both contribute to an increased risk of the severity of depression. Moreover, sleep quality plays a partial mediating effect between somatic symptoms and severity of depression, highlighting the importance of addressing sleep-related issues in the management of depression.

Objective: To examine the impacts of chemotherapy/radiotherapy, targeted therapy, and combined treatment on the quality of life in patients with intermediate and advanced lung cancer. Methods: The patients with intermediate and advanced lung cancer undergoing chemotherapy/radiotherapy, targeted therapy, and combined treatment for the first time were recruited from a tertiary hospital in Weifang City, Shandong Province, using a quota sampling method in September 2023. Basic information was collected using a general information questionnaire, and the quality of life was assessed using the Chinese version of Functional Assessment of Cancer Therapy-General. The investigation started on the 7th day of treatment, and the follow-ups were conducted at 3 and 6 months. The quality of life in patients with different treatment regimens and at different treatment time were compared using repeated measure analysis of variance. Results: There were 26 chemotherapy/radiotherapy patients, 32 targeted therapy patients, and 95 combination therapy patients. There were no significant differences in age, gender, place of residence, education level, self-rated economic status, medical insurance, pathological type and disease stage among the three treatment regimens (all P>0.05). The repeated measure analysis of variance showed an interaction effect between time and group among patients receiving the three treatment regimens (P<0.05). The quality of life scores of patients receiving combination therapy decreased with extended treatment time (all P<0.05). The quality of life scores of patients receiving targeted therapy at 3 and 6 months were lower than those treated for 7 days (both P<0.05). No significant differences were observed in quality of life scores among chemotherapy/radiotherapy patients with different treatment durations (all P>0.05). At 3 and 6 months, patients receiving combination therapy had lower quality of life scores compared to those receiving chemotherapy/radiotherapy or targeted therapy (all P<0.05). Conclusion The decline in quality of life for patients with intermediate and advanced lung cancer undergoing chemotherapy/radiotherapy and targeted therapy is less than that for patients receiving combined therapy.

[Objective] To evaluate the clinical application value of intrauterine perfusion with platelet-rich plasma (PRP) combined with in vitro fertilization-frozen-thawed embryo transfer (IVF-FET) in patients with chronic endometritis (CE). [Methods] A randomized controlled trial (RCT) was conducted, enrolling 60 CE patients undergoing artificial cycle frozen embryo transfer at our hospital from January 2022 to January 2024. Participants were randomly divided into three groups: Group A (routine frozen embryo transfer, n=20), Group B (routine frozen embryo transfer + one PRP intrauterine perfusion, n=20), and Group C (routine frozen embryo transfer + two PRP intrauterine perfusions, n=20). Endometrial thickness during the transformation and transplantation phases, uterine artery pulsatility index (PI), resistance index (RI), systolic peak velocity/end-diastolic velocity (S/D) ratio during transplantation, serum levels of IL-2, IL-4, IL-6, IL-10, and TNF-α during transplantation, as well as biochemical pregnancy rate, clinical pregnancy rate, live birth rate, and early miscarriage rate were compared across groups. [Results] No significant differences in endometrial thickness were observed among the three groups during the transformation phase (P>0.05). During the transplantation phase, endometrial thickness in Groups C and B was significantly higher than in Group A[9.54 (8.96-10.22) and 8.90 (8.34-9.72) vs 8.37 (7.89-8.75) mm, P<0.05], with Group C showing greater thickness than Group B (Z=3.733, P<0.05). Endometrial thickness in Groups C and B during transplantation was significantly increased compared to their respective transformation phases (Z=2.191, 2.462; P<0.05). Groups C and B exhibited lower PI, RI, and S/D values than Group A[PI:1.87 (1.77-1.97), 1.94 (1.88-2.15) vs 2.43 (2.35-2.49); RI:0.75 (0.73-0.77), 0.78 (0.75-0.81) vs 0.84 (0.83-0.86); S/D:2.61 (2.33-3.42), 3.01 (2.20-3.93) vs 3.72 (3.06-4.49); P<0.05]. Group C demonstrated lower PI and RI than Group B (P<0.05). IL-2 levels in Groups C and B were higher than in Group A[3.88 (2.71-5.01), 3.59 (2.73-4.38) vs 3.16 (2.11-3.25) ng/L, P<0.05], while IL-4, IL-6, IL-10, and TNF-α levels were significantly lower (IL-4: Z=1.428, 2.421; IL-6: Z=1.754, 2.435; IL-10: Z=1.754, 2.854; TNF-α: Z=1.961, 1.765; P<0.05). Group C had lower IL-6 levels than Group B (Z=3.976, P<0.05). Biochemical pregnancy rate, clinical pregnancy rate, and live birth rate in Group C were significantly higher than in Group A (75% vs 40%, 70% vs 35%, 60% vs 20%, P<0.05). No significant differences in early miscarriage rates were observed among the groups (χ²=3.750, P>0.05). [Conclusion] Intrauterine autologous PRP perfusion in CE patients enhances pregnancy and live birth rates, improves pregnancy outcomes post-FET, and demonstrates superior efficacy in endometrial repair and receptivity with two PRP perfusions compared to a single perfusion. This provides a safe and effective therapeutic option for optimizing outcomes in CE patients with prior implantation failure.

Objective:To analyze the intention to receive influenza vaccination and its associated factors among urban and rural residents aged≥50 in Zhejiang Province, China, in 2024.Methods:This cross-sectional study was conducted between March and May 2024 through a multi-stage intercept survey in 35 counties (cities, districts) selected from a total of 90 in Zhejiang Province, involving 175 communities/villages. The survey targeted residents visiting local hospitals and community health service centers/community health clinics. The questionnaire included basic demographic information, knowledge related to influenza prevention and treatment, chronic disease status, history of influenza vaccination, and intention to vaccinate. Urban and rural residents were classified based on their registered residence, according to the "Rules for Compilation of Statistical Regional Code and Urban-Rural Division Code" issued by the National Bureau of Statistics. Chi-square tests, ANOVA, and multivariate logistic regression models were used to analyze the factors influencing the intention to receive the influenza vaccine.Results:A total of 10 500 participants were surveyed, comprising 4 885 rural residents (46.52%) and 5 615 urban residents (53.48%). Of these, 3 430 rural residents (70.21%) and 3 718 urban residents (66.22%) expressed intention to receive the influenza vaccine. Multivariate logistic regression analysis revealed that for rural residents aged≥50, younger age groups (50-59 years: OR=1.747, 95% CI: 1.290-2.366; 60-69 years: OR=1.838, 95% CI: 1.401-2.411), history of influenza vaccination ( OR=6.721, 95% CI: 5.152-8.767), doctor′s recommendation for vaccination ( OR=3.788, 95% CI: 3.078-4.662), and higher scores on knowledge related to influenza prevention and treatment ( OR=1.090, 95% CI: 1.054-1.128) were significant promoting factors for vaccination intent. For urban residents aged≥50, belonging to the 60-69 age group ( OR=1.264, 95% CI: 1.023-1.563), history of influenza vaccination ( OR=5.392, 95% CI: 4.309-6.748), doctor′s recommendation for vaccination ( OR=5.307, 95% CI: 4.420-6.371), and higher scores on knowledge related to influenza prevention and treatment ( OR=1.051, 95% CI: 1.021-1.082) were significant promoting factors for vaccination intent. Conclusions:The intention to receive the influenza vaccination is notably high among residents aged≥50 in both urban and rural areas of Zhejiang Province, yet there remains potential for improvement. Age, history of influenza vaccination, doctor recommendation, and knowledge related to influenza prevention and treatment are significant factors influencing the intention to receive the influenza vaccination.

Objective:To analyze the pneumococcal vaccination rate and the influencing factors among residents aged≥50 in Zhejiang Province.Methods:This cross-sectional study was conducted between March and May 2024. A multi-stage intercept survey was used to intercept and survey 10 500 residents who visited or underwent physical examinations at 175 community health service centers/clinics in 35 counties (cities, districts) of Zhejiang Province. The questionnaire included basic demographic characteristics, history of pneumonia, chronic disease conditions, pneumococcal vaccination status, doctor recommendation, reasons for vaccination/non-vaccination, and channels for obtaining pneumococcal vaccine information. Participants were grouped based on demographic characteristics, chronic diseases conditions, history of pneumonia and doctor recommendations. The chi-square test was used to assess differences in vaccination rates among demographic groups while binary logistic regression models were used to identify factors affecting the vaccination rate.Results:Among the 10 500 surveyed participants, 1 724 (16.42%) had received pneumococcal vaccination. Binary logistic regression analysis revealed significantly higher vaccination rates among those who received a doctor recommendation compared to those without (26.25% vs 7.59%; OR=4.414, 95% CI: 3.851-5.059). Participants benefiting from the free vaccination policy showed higher vaccination rates than those who didn′t (47.59% vs 5.18%; OR=12.527, 95% CI: 10.723-14.634). The top three reasons for getting vaccinated against pneumonia were the free vaccination policy (65.43%), community promotion (52.15%), and family recommendations (42.34%). The top three sources through which respondents learned about the pneumococcal vaccine were television (64.64%), doctors (59.81%) and family members (50.92%). Conclusion:The pneumococcal vaccination rate among residents aged≥50 years in Zhejiang Province is relatively high but still needs further improvement, with vaccination rates closely associated with factors such as free vaccination policy and doctor recommendation.

Although a single nucleotide polymorphism for N-acetyltransferase 10 (NAT10) has been identified in patients with early-onset stroke, the role of NAT10 in ischemic injury and the related underlying mechanisms remains elusive. Here, we provide evidence that NAT10, the only known RNA N4-acetylcytidine (ac4C) modification "writer", is increased in the damaged cortex of patients with acute ischemic stroke and the peri-infarct cortex of mice subjected to photothrombotic (PT) stroke. Pharmacological inhibition of NAT10 with remodelin on Days 3-7 post-stroke or astrocytic depletion of NAT10 via targeted virus attenuates ischemia-induced infarction and improves functional recovery in PT mice. Mechanistically, NAT10 enhances ac4C acetylation of the inflammatory cytokine tissue inhibitor of metalloproteinase 1 (Timp1) mRNA transcript, which increases TIMP1 expression and results in the accumulation of microtubule-associated protein 1 light chain 3 (LC3) and progression of astrocyte autophagy. These findings demonstrate that NAT10 regulates astrocyte autophagy by targeting Timp1 ac4C after stroke. This study highlights the critical role of ac4C in the regulation of astrocyte autophagy and proposes a promising strategy to improve post-stroke outcomes via NAT10 inhibition.

Periodontal disease is a risk factor for many systemic diseases such as Alzheimer's disease and adverse pregnancy outcomes. Cleft palate (CP), the most common congenital craniofacial defect, has a multifaceted etiology influenced by complex genetic and environmental risk factors such as maternal bacterial or virus infection. A prior case-control study revealed a surprisingly strong association between maternal periodontal disease and CP in offspring. However, the precise relationship remains unclear. In this study, the relationship between maternal oral pathogen and CP in offspring was studied by sonicated P. gingivalis injected intravenously and orally into pregnant mice. We investigated an obvious increasing CP (12.5%) in sonicated P. gingivalis group which had inhibited osteogenesis in mesenchyme and blocked efferocytosis in epithelium. Then glycolysis and H4K12 lactylation (H4K12la) were detected to elevate in both mouse embryonic palatal mesenchyme (MEPM) cells and macrophages under P. gingivalis exposure which further promoted the transcription of metallopeptidase domain17 (ADAM17), subsequently mediated the shedding of transforming growth factor-beta receptor 1 (TGFBR1) in MEPM cells and mer tyrosine kinase (MerTK) in macrophages and resulted in the suppression of efferocytosis and osteogenesis in palate, eventually caused abnormalities in palate fusion and ossification. The abnormal efferocytosis also led to a predominance of M1 macrophages, which indirectly inhibited palatal osteogenesis via extracellular vesicles. Furthermore, pharmacological ADAM17 inhibition could ameliorate the abnormality of P. gingivalis-induced abnormal palate development. Therefore, our study extends the knowledge of how maternal oral pathogen affects fetal palate development and provides a novel perspective to understand the pathogenesis of CP.

Objective:To investigate the diagnostic value and influencing factors of endoscopic ultrasonography (EUS) for detecting rectal neuroendocrine neoplasms (R-NENs).Methods:A retrospective case-control study was performed on data of patients with suspected R-NENs by white light endoscopy who underwent endoscopic diagnosis and treatment or surgical operation and obtained pathological diagnosis at the Affiliated Hospital of Qingdao University from March 2016 to June 2023. Clinical data, EUS characteristics and pathological results were statistically analyzed, and the diagnostic accuracy of EUS for R-NENs were obtained by comparing the EUS results with the pathological results. Influencing factors affecting accuracy were analyzed by using the binary logistic regression model.Results:A total of 317 patients were included. The sensitivity, the specificity, the positive predictive value and the negative predictive value of EUS in diagnosing R-NENs were 98.03% (249/254), 34.92% (22/63), 85.86% (249/290) and 81.48% (22/27) respectively. The accuracy was 85.49% (271/317) and the Jorden index was 0.33. Tumor size ≤5 mm ( P=0.002, OR=2.892, 95% CI: 1.464-5.713), absence of surface vascular dilation ( P=0.019, OR=2.613, 95% CI: 1.170-5.837), normal tumor coloration ( P=0.001, OR=3.460, 95% CI: 1.645-7.279) and erythematous surface appearance ( P=0.048, OR=7.242, 95% CI: 1.015-51.680) were independent risk factors affecting the accuracy of R-NENs diagnosis by EUS. Depth assessment accuracy of EUS was 76.77% (195/254), with echo heterogeneity ( P<0.001, OR=4.008, 95% CI: 1.980-8.113) and surface depression ( P=0.035, OR=2.664, 95% CI: 1.073-6.615) emerging as significant factors affecting invasion depth evaluation. Conclusion:EUS demonstrates substantial clinical utility for R-NENs assessment, with diagnostic performance being significantly associated with tumor morphology and sonographic features. Macroscopic characteristics including tumor size, vascular patterns, and chromatic features influence diagnostic accuracy, while echo-textural heterogeneity and surface depression affect invasion depth precision. These findings underscore the clinical relevance of comprehensive EUS evaluation in R-NENs management.

Objective:To investigate the efficacy and safety of obinutuzumab combined with short-course dexamethasone in patients with relapsed immune thrombocytopenia (ITP) who had previously been treated with rituximab.Methods:A retrospective case series study was conducted. A total of 8 patients with relapsed ITP after treatment with rituximab who received obinutuzumab combined with short-course dexamethasone between January 2023 and January 2024 in the First Affiliated Hospital of Harbin Medical University were collected. The clinical characteristics, changes in platelet counts, changes in peripheral blood B-lymphocyte counts, treatment outcome and treatment-related adverse events were analyzed.Results:There were 1 male and 7 females in 8 patients with relapsed ITP after treatment with rituximab. The median age [ M ( Q1, Q3)] of the 8 enrolled patients was 52.5 (40.5, 56.0) years. The median relapsed times was 2.0 (2.0, 2.5) times and the median course of disease was 16.0 (13.0, 18.5) months. The platelet count increased from 8.73 (5.79, 11.65)×10 9/L pre-treatment to 180.00 (83.40, 255.00)×10 9/L post-treatment, and the difference was statistically significant ( Z = -2.37, P = 0.018); conversely, peripheral blood B-lymphocyte count decreased from 322.59 (148.29, 403.07) × 10 9/L pre-treatment to 1.23 (0.57, 1.76) ×10 9/L post-treatment, and the difference was statistically significant ( Z = -2.52, P = 0.012). After obinutuzumab and short-course dexamethasone treatment, 6 patients achieved complete remission, 1 case showed response, and 1 case had no response. No severe adverse events were observed during treatment and follow-up in all patients. Conclusions:Obinutuzumab combined with short-course dexamethasone appears to be effective in treating relapsed ITP patients after treatment with rituximab, and its safety is good.
