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 clinical efficacy of a novel sleep-aid decoction in treating elderly insomnia patients with different traditional Chinese medicine (TCM) constitutional types, and its effects on neurotransmitter and inflammatory factor levels. Methods A total of 200 patients with four different TCM constitutions-peaceful, Qi-deficient, Yin-deficient, and Yang-deficient-were recruited. Peripheral blood neurotransmitter and inflammatory factor levels were measured for variations among insomnia patients across different constitutions. These patients were treated using the novel sleep-aid decoction, the effects of which were evaluated based on changes in neurotransmitters and inflammatory factors. Results Compared to the peaceful constitution group, insomnia patients with Qi-deficient, Yin-deficient, and Yang-deficient constitutions exhibited significantly elevated baseline levels of neurotransmitters (5-HT, GABA) and inflammatory factors (IL-6, TNF-α, IL-1β, CRP). Following the treatment, the Qi-deficient and Yin-deficient groups showed a marked increase in 5-HT levels, restored balance of Glu, GABA, and melatonin, and significant reductions in IL-6 and TNF-α levels. The overall effective rate was 83.5%, with optimal efficacy observed in the Qi-deficient (97.72%) and Yin-deficient (95.34%) groups. Conclusion The novel sleep-aid decoction is effective in treating insomnia in elderly patients, with the best results observed in the Qi-deficient and Yin-deficient constitution groups.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

Objective:To explore the temporal and spatial distribution characteristics of reported incidence of schizophrenia in Ningbo from 2018 to 2022 and to provide a scientific basis for rational allocation of mental health resources and comprehensive prevention and treatment of schizophrenia.Methods:The reported incidence data of schizophrenia from 2018 to 2022 were collected from Ningbo's mental health information management system, and the reported incidence was calculated by township.

Conclusions The positive rate of AD preliminary screening among the elderly in Ningbo City is relatively high. Age, gender, economic conditions, exercise, social activities and physical conditions were factors affecting the positive rate of AD preliminary screening.

Objective: To investigate the mental health literacy levels among residents in Ningbo City, so as to provide the evidence for implementing the mental health service policy and targeted mental health education. Methods: Permanent residents at ages of 12 years and older were recruited in Ningbo City using the multi-stage stratified random sampling method from August to December, 2020. Subjects' mental health literacy levels were evaluated using the national mental health literacy survey of China, and the gender-, age-, region- and educational level-specific levels of mental health literacy were investigated. Results: A total of 6 654 questionnaires were allocated, and 6 392 valid questionnaires were recovered, with an effective recovery rate of 96.06%. The respondents included 2 967 men ( 46.42% ) and 3 425 women ( 53.58% ). The respondents were predominantly at ages of 18 to 44 years ( 2 705 residents, 40.19%) , lived in urban areas ( 3 823 residents, 59.81% ), and had an educational level of junior high school and below ( 3 195 residents, 49.98% ). The level of mental health literacy was 19.06%, and the score of mental health knowledge was ( 64.06±18.39 ) points. In the dimension of mental health skills, the scores of interpersonal support, cognitive reappraisal and transferred attention were ( 2.58±0.51 ), ( 2.45±0.57 ) and ( 2.82±0.49 ) points, and the score of mental health awareness was ( 3.63±0.47 ) points. A higher level of mental health literacy was seen in women than in men ( 20.64% vs. 17.22%, P<0.05 ) and in urban residents than in rural residents (20.95% vs. 16.23%, P<0.05 ). In addition, there were age- and educational level-specific levels of mental health literacy among residents ( P<0.05 ), and a higher level was seen in residents at ages of 18 to 45 years ( 28.98% ) and with a bachelor degree (40.89% ). Conclusions A high level of mental health literacy is found in residents in Ningbo City. Mental health promotion campaigns are recommended among men, rural elderly residents with a low educational level.

Objective: To survey on the home blood pressure measurement and blood pressure control rate among patients with hypertension in Beijing Yuetan community. Methods: A questionnaire survey was conducted among 504 hypertensive patients, who were visiting Beijing Yuetan Community Health Service Center and selected by convenience-sampling method during June 2018 to January 2019. The status of home blood pressure measurement, the awareness of hypertension, the blood pressure control rate and factors related to not regularly measuring were surveyed. Results: Of the 504 patients, 93.7% (472/504) took regular medication, but only 61.5% (310/504) had regular blood pressure measurements; 92.5% (466/504) had sphygmomanometers at home with electronic type mainly; 89.9% (453/504) patients knew the method of blood pressure measurement, but only 11.5% (52/453) had their sphygmomanometer calibrated. Among those who measured blood pressure, 77.4% (240/310) measured per week. The main reason for not measuring blood pressure regularly was that there was no need to measure blood pressure without any discomfort, accounting for 50.0% (97/194). The office blood pressure control rate (with desktop mercury sphygmomanometer) was 62.3% (314/504); the blood pressure control rate both in the morning and at bed time was 61.3% (73/119), that in the morning was 68.1% (81/119) and at bed time was 75.6% (90/119). The control rates of systolic blood pressure and heart rate by home measurement at morning and bedtime were significantly higher than those by office measurement (χ²=5.02, 9.97, 15.51, 13.72; all P<0.05). Conclusions The home blood pressure monitoring rate and knowledge level of hypertension among patients with hypertension in Yuetan community are relatively low. There are some differences in blood pressure control rate between office measurement and home measurement. Comprehensive evaluation is needed in the management process, and the treatment plan should be adjusted according to the specific condition of patients.

Objective To evaluate the effectiveness of standardized management for patients with type 2 diabetes in Beijing Qinan community.Methods Total 484 patients with type 2 diabetes in Qinan community were under standardized management.A cross-sectional study on the effectiveness of diabetes management was conducted in December 2016 based on the health records and clinic medical records.Results The mean age was(71.2 ± 11.2) years,the duration of diabetes was (12.2 ± 7.8) years,the mean BMI was(24.76 ± 3.06) kg/m2 in 484 patients.The TC was(5.08 ± 3.27) mmol/L and LDL-C was(2.72 ±0.78)mmol in 383 patients.The rate of achieving the target level of fasting blood-glucose was 51.96％ (199/383);the rate of achieving glycosylated hemoglobin target was 60.08％ (155/258);and the rate of achieving quick fasting blood-glucose target was 51.49％ (52/101).There were 80.37％ (389/484) patients with clinic blood pressure ＜ 140/90 mmHg(1 mmHg =0.133 kPa),36.57％ patients (177/484) had normal BMI;and 17.83％ patients (46/258) with controlled clinic blood pressure,fasting blood glucose,glycosaylated hemoglobin and LDL-C.There were 53.79％ patients with LDL-C ＜ 2.6 mmol/L and 23.24％ with HDL-C ≥ 1.0 mmol/L.The patients with fasting glucose ＜ 7.8 mmol/L had lower LDL-C than the patients with fasting glucose ≥ 7.8 mmol/L,(F =4.42,P =0.04),The patients with fasting glucose ＜ 7.8mmol/L had higher HDL-C than the patients with fasting glucose ≥ 7.8 mmol/L (Z =-2.30,P =0.02).The rate of achieving glycosylated hemoglobin target was decreased with the increasing of disease duration (x2 =12.57,P =0.01).Conclusion The comprehensive target-reaching rate of type 2 diabetes patients with standardization management in Qinan community is relatively low.It is necessary to strengthen the control of blood lipid,body weight and blood pressure for improving the effectiveness of standardized management of diabetic patients.

OBJECTIVE: To compare the applicability of three risk assessment methods on occupational health risk assessment of chemical harmful factors in lead-acid battery manufacturers. METHODS: The convenient sampling method was used to select six lead-acid battery enterprises as research subjects. The occupational health risks of jobs with lead smoke,lead dust and sulfuric acid were determined by contact ratio method,comprehensive index method( both are semiquantitative evaluation method) and qualitative risk assessment method. The assessment was carried out,and the obtained risk level was standardized as the risk ratio. The evaluation results of these three methods were compared. RESULTS: For occupational health risk levels of lead smoke,lead dust and sulfuric acid,the contact ratio assessment method were 2-4,and the comprehensive index method were 2-3. The risk ratios after standardization were consistent with the risk level of that before standardization. The result of the qualitative risk assessment method was 2-3,and the standardized risk ratio was 3-4. The risk ratio of each post after standardization increased by one level compared with the risk level before standardization. When( Exposure limit concentration,E)/( Occupational exposure limit,OEL) ≥ 2,the occupational health risk levels of lead smoke,lead dust of qualitative risk assessment method and the contact ratio method were completely consistent,both of which were high risk,which were higher than the medium risk result of the comprehensive index method. When E/OEL < 2,Kappa analysis results showed that the contact ratio method and the comprehensive index method were in good agreement( Kappa = 0. 84,P < 0. 01). The qualitative risk assessment method were inconsistent with the contact ratio method and the comprehensive index method( Kappa value were -0. 22 and -0. 24). CONCLUSION: For occupational health risk assessment of chemical harmful factors in lead-acid battery manufacturers,the comprehensive index method could be used to evaluate the comprehensive results of occupational disease hazard factors and OEL in workplace. A qualitative risk assessment method can be used for assessment without test method or OEL of occupational hazard factor.

Objective To compare the effectiveness and safety of Onyx and n-butyl-2-cyanoacryhte (NBCA) for the embolization of cerebral arteriovenous malformations (AVMs).Methods The clinical data of 53 patients with cerebral AVMs (31 in the NBCA group and 22 in the Onyx group) were analyzed retrospectively.The safety and effectiveness of the 1-year follow-up were compared.The size of AVMs (diameters ＜3 cm,3-6 cm,and ＞6 cm) and the Spetzler-Martin grade were used to conduct subgroup analysis.Results There were no significant differences in the baseline data and AVM morphologies.The embolization rate in the Onyx group was significantly higher than that in the NBCA group (P ＜ 0.05),but there were no significant differences in the incidences of postoperative hemorrhage (1/22 vs.1/31;P=1.000)and neurological deficit (1/22 vs.3/31;P=0.633) in the 1-year follow-up after procedure.The subgroup analysis showed that the embolization rates of the small and medium-sized cerebral AVMs in the Onyx group were significantly higher than those in the NBCA group (all P ＜ 0.05),and the embolization rates of cerebral AVMs with different Spetzler-Martin grades in were significantly higher than those in the NBCA group (all P ＜0.05).Conclusion Onyx is equivalent to NBCA in safety but better in efficacy.
