Objective: To investigate the Alzheimer's disease (AD) influencing factors among the elderly, so as to provide a basis for early prevention and intervention. Methods: From March to June 2024, participants aged 60 years and above from a sub-district in Haishu District, Ningbo City, Zhejiang Province were selected using a convenience sampling method. Data on demographics, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were evaluated using the short-form Geriatric Depression Scale. The Chinese Mini-Mental State Examination (MMSE) was used for the initial screening of AD, and individuals who screened positive were further diagnosed by psychiatrists. Factors affecting AD among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 3 644 individuals were surveyed, comprising 1 526 males (41.88%) and 2 118 females (58.12%). The mean age was (71.85±7.44) years. AD was detected in 200 cases, with a detection rate of 5.49%. Multivariable logistic regression analysis showed that individuals aged ≥65 years (65-<70 years, OR=3.012, 95%CI: 1.007-9.012; 70-<75 years, OR=3.131, 95%CI: 1.059-9.260; 75-<80 years, OR=5.779, 95%CI: 1.989-16.784; ≥80 years, OR=16.810, 95%CI: 5.926-47.685), those who were unmarried, divorced, or widowed (OR=1.973, 95%CI: 1.383-2.815), those with hearing loss (OR=1.573, 95%CI: 1.128-2.193), those with diabetes mellitus (OR=1.958, 95%CI: 1.362-2.814), and those with depressive symptoms (OR=4.143, 95%CI: 2.997-5.728) had a higher risk of AD. Conversely, individuals with an educational level of primary school or above (primary school, OR=0.579, 95%CI: 0.401-0.835; junior high school or above, OR=0.438, 95%CI: 0.259-0.741), and those who engaged in regular physical exercise (OR=0.414, 95%CI: 0.264-0.649) had a lower risk of AD. Conclusions The detection rate of AD was relatively high among the elderly in Haishu District. AD among the elderly was related to age, educational level, marital status, physical exercise, hearing loss, diabetes mellitus, and depressive symptoms.

Objective:To evaluate the relationship between gluten-free diet and rheumatoid arthritis (RA).Methods:Data were obtained from large-scale genome-wide association studies (GWAS), and genetic loci that are independent of gluten-free diet and RA of people of Europe2 were selected as instrumental variables. The gluten-free diet GWAS data included 64 949 individuals and 9 851 867 controls. Data were obtained from GWAS of 58 284 RA patients and 13 108 512 controls. The inverse variance weighted (IVW), MR Egger, weighted median method and weighted model were used to conduct two sample Mendelian randomization (MR) analysis. Cochran Q test and mendelian randomness pleiotropy residual sum and outlier (MR-PRESSO) were used to assess SNP heterogeneity. Applying the MR Egger intercept to test the level pleiotropy of SNP. The sensitivity analysis of the "leave one method" that evaluates whether MR studies were influenced by a single SNP. Results:After matching GFD and RA data, three SNPs were included as instrumental variables in the study. IVW showed that GFD could significantly reduce the risk of RA ( β=-60.83, s x=3.82, P<0.001). The weighted median method and weighted pattern also showed that the gluten free diet could reduce the risk of RA ( β=-57.97, s x=4.41, P<0.001; β=-55.81, s x=5.10, P=0.008). Sensitivity analysis of the correlation between GFD and RA showed that there might be heterogeneity between SNPs (Cochran Q test, Q=12.80, P=0.002). The MR-PRESSO results showed that no abnormal SNP was detected ( P=0.174). The forest map showed that SNPs was closely related to GFD and RA stability. The method comparison chart showed that the results of multiple testing methods were basically consistent. The funnel plot showed that SNPs were basically symmetrical, indicating that there was no pleiotropy in MR analysis. The MR Egger intercept test showed no horizontal pleiotropy in MR analysis (intercept value was-0.24, P=0.174). The sensitivity analysis of the "leave one method" is suggested that no single SNP had a significant impact on the overall results. Conclusion:Gluten free diet is related to the risk reduction of RA.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.

Objective:To compare the treatment effect of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) patients in the prophylactic distal perfusion catheter (DPC) and the non-prophylactic DPC.Methods:A prospective randomized controlled trial (RCT) was conducted. Patients who received VA-ECMO treatment were reviewed at Affiliated Jinhua Hospital, Zhejiang University School of Medicine from January 2019 to June 2020 were divided into two groups, the prophylactic DPC group (DPC placed immediately after the patient VA-ECMO) and the non-prophylactic DPC group (the DPC was placed after the early limb ischemic signs by using evaluation of the lower extremity perfusion assessment table). Comparing the differences of clinical data of two group patients. Pearson correlation analysis was used to analyze the correlation between peak velocity of dorsalis pedis artery and peak velocity of posterior tibial artery and transcutaneous oxygen partial pressure (TcPO 2). Results:A total of 62 patients were included in the analysis, with 31 cases in prophylactic DPC group and another 31 cases in non-prophylactic DPC group. There were no significant differences in sex, age, body mass index (BMI), smoking index, underlying disease, catheterization site, recovery time before on machine, extracorporeal membrane oxygenation (ECMO) operation time, mechanical ventilation time, length of stay in intensive care unit (ICU), mortality rate in hospital, and acute physiology and chronic health evaluationⅡ(APACHEⅡ) between the preventive DPC group and the non-preventive DPC group. There was no significant difference in ECMO indications, ECMO intubation location and pipeline type. The bleeding in the non-prophylactic DPC group was lower than that in the non-prophylactic DPC group [6.5% (2/31) vs. 29.0% (9/31), P < 0.05]. There were no significant differences in limb complications such as cyanosis, necrosis, amputation, compartment syndrome, arterial thrombosis, vascular reconstruction and repair, pseudoaneurysm, limb ischemic or limb infection. During the ECMO operation, except the blood stream infection in the non-prophylactic DPC group was lower than that in the non-prophylactic DPC group [3.2%(1/31) vs. 19.4% (6/31), P < 0.05], there was no other statistical difference in complications between the two groups. The peak velocity of dorsalis pedis artery in the preventive DPC group was significantly higher than that of the non-preventive DPC group (cm/s: 19.30±10.85 vs. 17.85±8.55, P < 0.05), and the peak velocity of posterior tibial artery was significantly lower than that of the non-preventive DPC group (cm/s: 19.90±10.94 vs. 21.58±9.77, P < 0.05). Pearson correlation analysis showed that the peak velocity of dorsalis pedis artery and peak velocity of posterior tibial artery of the preventive DPC group and the non-preventive DPC group were positively correlated with TcPO 2 ( r values were 0.747, 0.856, 0.850, 0.813, respectively, and P values were all 0.000). Conclusions:For patients with VA-ECMO treatment, the incidence of blood stream infection and bleeding during ECMO operation in non-prophylactic DPC implantation patients is lower than that of prophylactic DPC implantation patients. TcPO 2 is positively correlated with peak velocity of posterior tibial artery and dorsal foot artery in the cannulated limb. In patients with VA-ECMO undergoing femoral artery and vein puncture, in addition to judging the blood supply of lower limbs according to symptoms and signs, ultrasound and TcPO 2 monitoring can also be used as effective monitoring methods.

There were significant differences in the dimensions of depersonalization in different age, weekly work time, personal monthly income, working system and occupational stress groups ( P<0.05) . There were significant differences in the dimensions of low individual achievement in different education levels, weekly work time, working system and occupational stress groups ( P<0.05) . Conclusion:The female workers of labor-intensive enterprises are generally have mild to moderate job burnout. The main influencing factors of job burnout are weekly work time and occupational stress.

Iodine transporters of basement membrane of thyroid follicular epithelial cells can participate and exchange the iodine ions across intracellular and extracellular. Among all of the iodine rich organs, iodine ions which only exist in colloidal of thyroid follicular epithelial cells can be functioned as the raw materials, which after oxidation, iodization and coupling, to synthesize thyroid hormone (TH) and to exert its biological functions. Therefore, the iodine transported function of iodide transporters plays a pivotal role for TH biosynthesis. Furthermore, functional studies show that the abnormal expression or dysfunction of iodide transporters might serves as tumor promoters or inhibitors via regulated the mTOR signal pathway, the MAPKs signal pathway, and the NF-κB signal pathway, together contributed to the regulation of cell proliferation, invasion, metastasis and apoptosis, in which plays the role of non iodide transported function. Therefore, the non iodine transported function of iodide transporters may plays the crucial role of tumor occurrence and progression of carcinoma. Based on this information, present study was devoted to systematic summarize the iodine transported function and non iodine transported function (may affects occurrence and progression of carcinoma) of the classical iodide transporters [sodium iodide symporter (NIS) and pendrin] and novel iodine transporters[ (cystic fibrosis transmembrane conductance regulator (CFTR) , sodium multivitamin transporter (SMVT) , and anoctamin 1 (ANO1) ], respectively, in order to provide a theoretical basis and literature review reference for underlying the mechanism of iodine transporters and its regulated signal pathways for the occurrence and progression of carcinomas.
