Curcumin is a natural yellow pigment， a natural phenolic antioxidant extracted from the rhizomes of Curcuma longa and Curcumae Rhizoma of the ginger family， with anti-inflammatory， anti-tumor and antioxidant properties. In recent years， it has been found that curcumin also has good antidepressant properties， and it is considered a safe and effective antidepressant potential drug. The mechanism of curcumin’s antidepressant efficacy mainly includes regulating neurotransmitters， modulating the hypothalamic-pituitary-adrenal axis， regulating brain-derived neurotrophic factor， inhibiting neuroinflammation， inhibiting oxidative stress， and regulating gut microbiota， etc.， and there is an overlapping and synergistic therapeutic effect of the above mechanisms. At present， the antidepressant mechanism of curcumin is still not fully understood， and will be combined with multi-omics technology， new formulation technology， and clinical trials to obtain further breakthroughs in the future.

Objective: The impact of prophylactic salpingectomy on the prevention of epithelial ovarian cancer (EOC) remains unclear, particularly in Asian populations where data is lacking. In this systematic review and meta-analysis study, we sought to assess whether prophylactic salpingectomy could reduce the incidence of ovarian cancer in the general population of multiple ethnicities. Methods: A systematic review and meta-analysis were conducted using PubMed/MEDLINE, EMBASE, the Cochrane Library, and Web of Science to assess the effectiveness of salpingectomy, bilateral salpingectomy (BS), and unilateral salpingectomy (US) in reducing the risk of EOC and evaluating postoperative outcomes. Results: The final analyses included 6 eligible trials (5,747,056 patients), including 1 cohort study and 5 case-control studies. The analyses of these studies demonstrated that women who underwent salpingectomy had a significantly reduced risk of EOC compared to those who did not receive salpingectomy (odds ratio [OR]=0.63; 95% confidence interval [CI]=0.45–0.89; p=0.007). Five studies (5,746,469 patients) indicated a significant reduction in EOC risk among patients who underwent BS (OR=0.48; 95% CI=0.33–0.69; p<0.001).On the other hand, in the analysis of 4 studies (5,745,887 patients) that examined US, the association with EOC risk was not significant despite the protective trend (OR=0.82; 95% CI=0.64–1.06; p=0.12). Conclusion Our results indicate BS is an effective strategy for reducing the risk of sporadic EOC, but the results did not lead to the same conclusion for patients who underwent US. When a candidate or patient is undergoing a hysterectomy or has other benign diseases, prophylactic BS may be a safe surgical procedure that carries future benefits in terms of EOC risk.

Non-small cell lung cancer (NSCLC) is the most important histological type of lung cancer. This disease affects a large number of patients, and the prognosis of advanced patients is poor. Although great progress has been achieved for existing treatment methods, challenges still exist. Cancer is a genetic disease, and its occurrence is accompanied by substantial genomic-sequence instability. (GT/CA)_n repeat sequence is a common microsatellite sequence serving as transcriptional function-related regions, DNA-methylation modification sites, and other functional sites. Its polymorphism is closely related to the expression of EGFR, HO-1, and HIF-1α in NSCLC patients. (GT/CA)_n repeat sequence is the breakthrough point to explore the molecular mechanism of NSCLC occurrence and development, develop molecular markers for diagnosis and prognosis and epigenetics research. This paper summarizes the studies on (GT/CA)_n repeat polymorphisms in NSCLC with the aim of providing references for relevant NSCLC research.

ObjectiveTo identify the possible health impact of the 14th five⁃year plan for the development of employment and social security in Deqing County and propose improvement measures through health impact assessment. MethodsBased on the data of Deqing County， stakeholder interviews and Delphi Consultation Method， this study described the current status of employment and social security and analyzed the potential health impacts of implementing the 14th five⁃year plan for the development of employment and social security in Deqing County. ResultsThrough a quick assessment process， the results showed that the implementation of the plan would bring mixed health impacts. Positive impacts included enhanced social security capacity， improved health levels of low-income populations and families， increased convenience of medical treatment， and improved efficiency of health services. Negative impacts included reduced accessibility of digital services for the elderly， increased gap in benefits for retirees， increased risk of discrimination against disabled individuals， increased risks of layoffs and unemployment for vulnerable groups， and increased employment instability for middle-aged and elderly populations. ConclusionThe 14th five⁃year plan for the development of employment and social security in Deqing County will bring a series of positive health impacts， but negative health impacts also warrant attention.

Objective To explore the impact of the sialic acid binding lectin-E(Siglec-E)on the inhibitory properties of parthenolide(PTL)against lipopolysaccharide(LPS)-induced M1 polarization of microglia(BV2).Methods ①Single cell sequencing data of Siglece related mouse brain tissue was obtained from Gene Expression Omnibus(GEO)database and divided into the WT group(n=3)and the Siglece-/-group(n=4).The microglia cells were screened,and the enrichment analysis was performed to analyze related differential genes and pathways.BV2 cells were constructed by the shRNA interference technique and were divided into NC-shRNA and Siglece-shRNA to detect the expression level of Siglec-E(Siglece).② NC-shRNA and Siglece-shRNA cells were respectively divided into the Control group,LPS group,PTL group and PTL+LPS group(n=3).The mRNA levels of markers of M1 polarization in microglia,iNOS,IL-1 β and IL-6,were detected by RT-qPCR.Siglecefl/fl and Cx3cr1cre mice were mated to obtain microglia-specific Siglece deletion(Siglecefl/fl×Cx3cr1cre)mice,and LPS-induced neuroinflammation model was established.③ Nine WT and Siglecefl/fl×Cx3cr1cre male mice were assigned to the Control group,LPS group and PTL+LPS group(n=3).RT-qPCR,immunofluorescence assay and Western blotting were used to verify the knock-out effect and polarization-related pathways,and to investigate the mechanism of Siglec-E affecting PTL inhibition of M1 polarization of microglia.Results Compared with the NC-shRNA group,the expression of Siglec-E in the Siglece-shRNA group was significantly decreased(P<0.01),indicating that the Siglec-E knock-down cell model was successfully established.With the stimulation of LPS,mRNA levels ofiNOS,IL-1 β and IL-6 were significantly up-regulated compared with the Control group both in shRNA cells and Siglece-shRNA cells(P<0.01).With the influence of PTL and LPS,the markers of M1 polarization in NC-shRNA cells mentioned before were significantly decreased(P<0.05),while for Siglice-shRNA cells,there were no significant changes in the markers of M1 polarization.PTL inhibited the phosphorylation of JNK and IκB protein(P<0.01)and the nuclear translocation of NF-κB in BV2 cells,down-regulated Siglec-E,and weakened the inhibitory effect.Compared with mice in the WT group,the expression of Siglec-E in microglia of Siglecefl/fl×Cx3cr1cre mice was decreased significantly(P<0.01),and the inhibitory effect of PTL on the phosphorylation of NF-κB in microglia of Siglecefl/fl×Cx3cr1cre mice was also decreased.Conclusion The absence of Siglec-E in microglia attenuates the inhibition of M1 polarization by the MAPK/NF-κB pathway targeted by PTL.

Objective To investigate the application value of dual-layer spectral computed tomography(DLCT)45 keV single energy image in follow up after transcatheter arterial chemoembolization(TACE)for hepatocellular carcinoma(HCC).Methods The DLCT images of 60 patients with HCC after TACE treatment were analyzed retrospectively.The CT value and standard deviation(SD)value of the lesion region of interest(ROI)and surrounding normal liver parenchyma on two kinds of images with 45 keV energy spectrum CT and 120 kVp conventional CT were measured respectively,then the contrast-to-noise ratio(CNR)between the lesions and surrounding normal liver parenchyma was calculated,and their differences were compared.The image quality of the two kinds of images was scored subjectively with the 3-point method,and the patients were divided into different groups according to the enhance-ment degree and tumor staining.The receiver operating characteristic(ROC)curve was also drawn.Results(1)There was no signif-icant difference in CNR between arterial phase,portal phase,and delayed phase of 120 kVp conventional CT(Hc=1.128,P>0.05).The CNR of 45 keV energy spectrum CT was higher than that of 120 kVp conventional CT,with a statistically significant difference(Z=5.060,P<0.05).(2)The subjective score of 45 keV energy spectrum CT was higher than that of 120 kVp conventional CT,and the difference was statistically significant(Z=5.335,P<0.05).ROC curve analysis showed that 45 keV energy spectrum CT had a larger area under the curve(AUC)than 120 kVp conventional CT,and the difference was statistically significant(Z=4.136,P<0.001).Conclusion 45 keV energy spectrum CT image can significantly improve the CNR between tumor and normal liver parenchyma,and it has the better image quality and higher diagnostic efficiency.

Breast cancer is the most diagnosed cancer in women worldwide and the leading cause of most cancer-related deaths,posing a serious threat to women′s health worldwide.At present,although the prognosis of some patients with breast cancer has improved,the emergence of drug resistance and the metastasis and recurrence of breast cancer are still the main reasons for poor prognosis.CD36 is a multiligand transmembrane glycoprotein expressed on various cell types.In recent years,studies have confirmed that CD36 can reshape the lipid metabolism of cancer cells;promote the differentiation of tumor-related macrophages into M2 type and recruitment into tumor tissues;regulate the function of Treg cells,CD8+T cells,DCs,and other immune cells,and thus promote tumor development.In addition,CD36 is also associated with breast cancer stem cells,metastasis-initiating cells,and breast drug resistant cells.Therefore,CD36 could be an important potential therapeutic target for breast cancer.

ObjectiveTo explore the characteristics and major factors influencing mental health literacy (MHL) among non-graduating middle school and high school students in Taizhou, Zhejiang Province, and to provide a reference for the promotion of mental health literacy among adolescents. MethodsFrom September to October 2023, a stratified random cluster sampling method was used to conduct a questionnaire survey among students from three classes each in non-graduating grades in four middle schools and four high schools in Taizhou, Zhejiang Province. The survey included basic demographic information, a Structured Mental Health Literacy Questionnaire (MHLQ), and other psychological scales [Educational Stress Scale for Adolescents (ESSA), Perceived Choice Single Scale (PC), Child Depression Inventory (CDI), Generalized Anxiety Disorder (GAD), The University of California at Los Angeles 3-item Loneliness Scale (UCLA-3) and Multidimensional Scale of Perceived Social Support (MSPSS)]. t-tests, chi-square tests, analysis of variance (ANOVA), and multiple linear regressions were applied for the statistical analysis of the data. ResultsThe mental health literacy average score of 2 094 students was (82.3±15.8) points, with a mean of (4.1±0.8) points. The dimension of belief in mental health rights had the highest score. There were significant differences in the mental health literacy score across different dimensions for students with different household registration, economic levels, academic performance, and father’s education level (P<0.001). Multiple linear regression analysis indicated that rural household registration, lower paternal education level, greater academic pressure, a weaker sense of control over one’s behavior, less social support, and symptoms of loneliness, depression, or anxiety were associated with poorer mental health literacy among the students. ConclusionThe mental health literacy of middle school and high school students in Taizhou is generally good, but there are differences among students with different characteristics. Targeted interventions should be carried out for students from rural areas, with poorer mental health, and less low social support to improve the overall mental health literacy of adolescents.
