More than 80% of the world’s populations are at risk of vector-borne diseases, with mosquito-borne diseases as a significant global public health problem. Mosquito populations control is critical to interrupting the transmission of mosquito-borne diseases. This review summarizes the physical attributes, smell, vision, touch, and hearing of mosquitoes to unravel the preferences of female mosquitoes, and describes the mechanisms underlying the best male mating by female mosquitoes, so as to provide new insights into management of mosquito-borne diseases.

Objective To investigate the correlation between the appendicular skeletal mass index(ASMI)and os-teoporosis(OP)in postmenopausal patients with type 2 diabetes(T2DM).Methods 164 hospitalized postmeno-pausal elderly T2DM patients were selected and their bone density(BMD)and appendicular skeletal mass were measured using dual energy X-ray absorption method(DXA).ASMI=appendicular skeletal mass/height2(kg/m2),and they were divided into OP group and non OP group based on T value.The general clinical data,blood biochemical indicators,and ASMI between the two groups were compared,and Logistic regression analysis,ROC curve were further used to analyze the correlation and diagnostic power.Results Compared with non OP group,OP group had a higher incidence of sarcopenia(SAC)(P＜0.05);the differences in age,ASMI,body mass index(BMI),and estradiol(E2)had significant differences between the two groups(P＜0.05);Logistic regression analysis showed that the reduction of ASMI[OR=0.133,95％CI(0.029-0.611)],BMI[OR=0.785,95％CI(0.625-0.985)],and E2[OR=0.967,95％CI(0.942-0.993)]were protective factors for OP;receiver operating curve(ROC)suggested that the AUC of ASMI for OP prediction was 0.752[95％CI(0.632-0.872),P＜0.001]with sensitivity 87.5％,specificity 47.8％,and the best diagnostic value was 5.52 kg/m2.Conclusion The reduction of ASMI,BMI,and E2 is positively correlated with the occurrence of osteoporosis.ASMI is an important protective factor for osteoporosis.Early OP screening and risk factor assessment should be conducted for elderly postmenopausal T2DM patients,and early intervention measures should be taken to reduce the risk of falls and fractures.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective To investigate the relationship and potential pathways between metal(loid)exposure and the risk of polycystic ovary syndrome(PCOS)in women of childbearing age. Methods This case-control study included 200 patients with PCOS(cases)and 896 non-PCOS controls with the age of 25-37 years.The concentrations of 29 metal(loid)s in the follicular fluid(FF)and clinical indicators in the serum were measured in all participants.Logistic regression analysis and mediation analysis were conducted to evaluate the associations between metal(loid)exposure and PCOS risk and investigate the possible roles of clinical indicators,respectively. Results Logistic regression analysis revealed an association between high copper levels in FF and increased PCOS risk(highest vs.lowest quartile:adjusted odds ratio=2.94,95%confidence interval:1.83-4.72).A high luteinizing hormone/follicle-stimulating hormone ratio and elevated levels of testosterone and anti-Müllerian hormone(AMH)were strongly associated with increased PCOS risk induced by high copper exposure.The mediation analysis indicated a mediating effect of AMH in the association between copper exposure and PCOS risk. Conclusion Copper may affect PCOS risk through the hypothalamic-pituitary-ovarian axis,mediated by AMH.Copper exposure and internal AMH levels are important indicators for early warning of PCOS development.

Objective:To explore the current status of intrinsic capacity in elderly patients with hospitalization-associated disability (HAD) and explore its influencing factors.Methods:From November 2023 to January 2024, convenience sampling was used to select 203 elderly patients with HAD at Xuanwu Hospital of Capital Medical University as the study subjects. A survey was conducted on elderly patients using the General Information Questionnaire, Fried Frailty Phenotype, Barthel Index, Social Support Rating Scale, and Intrinsic Capacity Assessment Tool. Binomial Logistic regression was used to analyze the influencing factors of intrinsic capacity in elderly patients with HAD.Results:A total of 203 questionnaires were distributed, and 199 valid questionnaires were collected, with a valid response rate of 98.03% (199/203). The total score of intrinsic capacity in 199 elderly patients with HAD was 5.00 (4.00, 6.00), with scores for cognitive dimension, psychological dimension, motor dimension, vitality dimension, and sensory dimension being 1.00 (1.00, 2.00), 2.00 (1.00, 2.00), 0 (0, 1.00), 1.00 (1.00, 1.00) and 1.00 (1.00, 1.00), respectively. The binomial Logistic regression showed that department of medicine and surgery, self-rating health status, social support, serum albumin, and Barthel Index were the influencing factors of intrinsic capacity in elderly patients with HAD ( P<0.05) . Conclusions:The intrinsic capacity of elderly patients with HAD is at medium to low level, with the most severe impairment in the motor dimension. Medical and nursing staff should develop personalized rehabilitation measures for elderly HAD patients based on the influencing factors of their intrinsic capacity, enhance their intrinsic capacity, and reduce the burden of care on families and society.

Objective:To investigate the status and influencing factors of different types of cognitive frailty in aged inpatients with hypertension.Methods:Totally 300 aged patients with hypertension admitted to the Cardiology, Geriatrics, and Endocrinology Departments of Xuanwu Hospital, Capital Medical University, from April to October 2022 were selected by convenience sampling. Data were collected using a general information questionnaire, the Fried Frailty Phenotype (FP), the Mini-Mental State Examination (MMSE), the 9-item Subjective Cognitive Decline Questionnaire-9 (SCD-Q9), the Morisky Medication Adherence Scale (MMAS), the Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression Scale (HADS), the Social Support Rating Scale (SSRS), and the Mini Nutritional Assessment (MNA) .Results:A total of 300 questionnaires were distributed and returned, yielding a 100.00% response rate. Among the 300 aged hypertensive patients, 74 were diagnosed with reversible cognitive frailty (RCF) and 98 with potentially reversible cognitive frailty (PRCF). Logistic vegression analysis showed that, factors influencing RCF included daily exercise habits and the use of thiazide diuretics ( P<0.05) ; factors influencing PRCF included age, pre-retirement occupation, daily exercise habits, sleep quality, Barthel Index score, and serum albumin levels ( P<0.05) . Conclusions:The status of both RCF and PRCF is relatively high among aged inpatients with hypertension. The influencing factors for different types of cognitive frailty vary. Targeted interventions based on both common and specific influencing factors should be developed to reverse or slow the progression of cognitive frailty in aged hypertensive patients.

Objective:To explore whether the food additive sodium benzoate(NAB) induces pancreatic inflammation and β cell apoptosis through the benzoylation(Kbz) modification pathway.Methods:In vivo experiments: C57BL/6J male mice(8 weeks old, 18-20 g) were randomly divided into normal control group(double distilled water feeding) and NAB feeding group(1 g/kg NAB feeding). Blood glucose were measured. After 20 weeks, fasting serum insulin, interleukin(IL)-18, IL-1β, and benzoyl-CoA levels were detected by ELISA method. Bax, IL-18, Pan-Kbz and Pan-Kac were detected by immunohistochemistry staining. In vitro experiments: β-TC-6 cells were cultured with NAB(6 mmol/L) or benzoyl-CoA(100 μmol/L) as stimulator and acyltransferase P300 inhibitor A485(10 μmol/L) as intervention factor. 24 hours later, inflammation, apoptosis, insulin secretion and Pan-Kbz level were detected by qRT-PCR, ELISA and Western blotting.Results:In the in vivo experiments, compared to the NC group, mice in the NAB group exhibited impaired glucose tolerance, decreased fasting insulin levels, significantly increased serum benzoyl coenzyme A concentrations, relatively elevated pancreatic IL-1β, IL-18, and Bax protein expressions, increased levels of Pan-Kbz, while Pan-Kac levels were downregulated(all P<0.05); In vitro experiments, NAB dose-dependently inhibited insulin secretion, promoted the release of Pan-Kbz and inflammatory factors IL-18 and TNF- α, inhibited Bcl-2 expression and up-regulated Bax expression, A485 reversed NAB-induced Pan-Kbz modification, improved NAB-induced inflammation and apoptosis, and promoted insulin secretion(all P<0.05). Conclusion:NAB may induce pancreatic inflammation, β-cell apoptosis, and impair insulin secretion through Kbz modification pathway.

Objective To investigate the relationship between serum periostin (POSTN) level and bone mineral density in patients undergoing maintenance hemodialysis (MHD). Methods Ninety-five patients who had received MHD treatment for more than 3 months in the Hemodialysis Center of Qingdao Municipal Hospital from October 2022 to October 2023 were enrolled as experimental group. Meanwhile, 50 healthy individuals undergoing health examinations in the Physical Examination Center of the same hospital during the same period were selected as the control group. Clinical data such as gender and age were collected for both groups. Fasting venous blood samples were collected before dialysis to measure parathyroid hormone (PTH), alkaline phosphatase (ALP), urea nitrogen, serum creatinine, serum calcium, serum phosphorus, and other indicators. Serum POSTN levels in MHD patients and healthy individuals were determined using enzyme-linked immunosorbent assay (ELISA). The correlation between serum POSTN levels and bone mineral density in MHD patients was explored. Univariate and multivariate binary Logistic regression analyses were performed to identify risk factors for low bone mineral density in MHD patients and assess the clinical value of serum POSTN level in predicting low bone mineral density in these patients. Results The serum POSTN level in the experimental group were significantly higher than those in the control group (P < 0.05). These patients were divided into two groups based on T-values: normal bone mass group(47 cases, T value >-1.0) and low bone mineral density (48 cases, T value≤-1.0). The low bone mineral density group had significantly higher serum POSTN levels, dialysis vintage, PTH, ALP, serum phosphorus, β₂-microglobulin levels, and a higher proportion of females compared to the normal bone mass group (P < 0.05). Pearson correlation analysis revealed negative correlations of bone mineral density T values with serum POSTN, dialysis vintage, C-reactive protein, PTH, ALP, serum phosphorus, and β₂-microglobulin in MHD patients (r=-0.695, -0.688, -0.246, -0.528, -0.216, -0.309, -0.293; P < 0.05). Multivariate binary Logistic regression analysis showed that after adjusting for confounding factors such as dialysis vintage, PTH, and ALP, high serum POSTN level was an independent risk factor for low bone mineral density in MHD patients. The receiver operating characteristic (ROC) curve indicated that the area under the curve (AUC) for serum POSTN level in predicting low bone mineral density in MHD patients was 0.901, with a cut-off value of 29.66 ng/L. Conclusion MHD patients have higher serum POSTN levels than healthy individuals, and this marker is associated with low bone mineral density in MHD patients.

Objective: To investigate the role of Vitamin D in the pathogenesis of inflammatory bowel disease (IBD) by studying the changes of inflammation related genes in peripheral blood mononuclear cells ( PBMC) .
