ABSTRACT
Objective:To investigate the cognitive function and its influencing factors among residents in Qingdao city.Methods:The 5 311 research subjects over 65 years old were selected from Qingdao by simple random sampling and stratified sampling. All subjects were investigated by AD8 dementia early screening questionnaire and community screening instrument dementia (CSI-D) to evaluate the prevalence of cognitive decline in this study.The score of AD8 dementia early screening questionnaire ≥2 points or the score of CSI-D ≤7 points was considered to be cognitive decline. Mann-Whitney U test, Chi-square test, Fisher exact probability method, univariate and multivariate Logistic regression analysis and Bootstrap verification were performed using SPSS 26.0 software. Results:Among 5 311 subjects, 1 899 subjects had normal cognitive function (35.76%) and 3 412 subjects had cognitive decline (64.24%). The age of the cognitive decline group was significantly higher than that of the normal group ( P<0.01). There were significant differences in gender, educational level, rural residents, marital status, chronic medical history, hypertension, rheumatoid arthritis, cerebrovascular disease, intervertebral disc disease, ischemic heart disease, monthly household income and alcohol consumption between the two groups (all P<0.05). Univariate Logistic regression analysis showed that female ( β=0.313, OR=1.367, 95% CI=1.221-1.530), age ( β=0.052, OR=1.053, 95% CI=1.043-1.063), rural residents ( β=0.850, OR=2.340, 95% CI=2.042-2.682), widowed ( β=0.557, OR=1.745, 95% CI=1.500-2.029), chronic medical history ( β=0.290, OR=1.336, 95% CI=1.191-1.498), hypertension ( β=0.134, OR=1.143, 95% CI=1.020-1.281), rheumatoid arthritis ( β=0.458, OR=1.581, 95% CI=1.222-2.046), cerebrovascular disease ( β=0.584, OR=1.794, 95% CI=1.352-2.380), intervertebral disc disease ( β=0.578, OR=1.782, 95% CI=1.370-2.319), ischemic heart disease ( β=0.501, OR=1.651, 95% CI=1.272-2.143) were the risk factors for cognitive decline. Higher education level, higher monthly household income and abstinence ( β=-0.244, OR=0.783, 95% CI=0.619-0.992) were protective factors for cognitive decline. Multivariate logistic regression analysis showed that age ( β=0.035, OR=1.036, 95% CI=1.025-1.047), rural residents ( β=0.215, OR=1.239, 95% CI=1.047-1.468), chronic medical history ( β=0.191, OR=1.210, 95% CI=1.067-1.372), cerebrovascular disease ( β=0.480, OR=1.616, 95% CI=1.195-2.187), intervertebral disc disease ( β=0.456, OR=1.578, 95% CI=1.190-2.094) were risk factors for Alzheimer's disease. Higher education level and higher monthly household income were protective factors for Alzheimer's disease. Conclusion:The elderly with chronic diseases, low income and low education level may be at the high risk of cognitive function decline, which should be paid attention to in early screening and intervention.
ABSTRACT
Objective To investigate the influence of the variations of an epidemic focus on hemorrhagic fever with renal syndrome (HFRS) so as to provide a basis for effective control of HFRS.Methods HFRS epidemic data from the rapid development of urbanization of Huangdao District and the general development of Jiaonan City were collected and analyzed retrospectively from 1979 to 2014.And the HFRS cases,incidences,host animals and Hantavirus surveillances were compared.Results The three epidemic peaks occurred from 1979 to 2014 in Huangdao District and Jiaonan City,they were in the mid-1980s (1983-1987),the late 1990s (1995-1999) and around 2012 (2010-2014),and 954,80,37 and 2 506,614,432 cases were reported,respectively,in Huangdao District and Jiaonan City.The three peak years were 1986,1999 and 2012.And the annual incidences of Huangdao District were 385.73/100 000,15.64/100 000 and 2.51/100 000,respectively.The annual incidences of Jiaonan City were 67.07/100 000,28.68/100 000 and 14.68/100 000,respectively.The three peaks obviously appeared double peaks [the autumn and winter (from Oct.to Dec.) and the spring (from Jan.to Feb.)] in Jiaonan City.And the first peaks in Huangdao District was in the autumn and winter (from Oct.to Dec.) and the spring (from Jan.to Feb.),the second and the third were only in the autumn and winter (from Oct.to Dec.).Eight kinds of host animals were detected in Jiaonan City from 2005 to 2014.They were house mouse [27.53％ (1 108/4 024)],brown rat [25.50％ (1 026/ 4 024)],striped field mouse [14.84％ (597/4 024)],black rat [10.74％ (432/4 024)],hamsters [11.01％ (443/4 024)],shrew [8.72％ (351/4 024)],back grain hamster [1.02％ (41/4 024)] and club rat [0.65％ (26/4 024)].Two kinds of host animals were detected in Huangdao District.They were house mouse [57.14％ (16/28)] and brown rat [42.86％ (12/28)].The capture rates in Jiaonan City were higher than those of Huangdao District.The capture rate in 2012 was 8.04％ (855/10 638) and the capture rates in Huangdao District were all lower than 0.84％.The total detection rate in Jiaonan City was 2.81％ (113/4 024).And there was no positive detection for ten years in Huangdao District.Conclusions HFRS epidemic intensities have receded gradually in Huangdao District and Jiaonan City.The epidemic in Huangdao District obviously presents a low epidemic condition after the first peak.The few kinds and low densities of host animals are resulting in the sustainable condition.The evolution of epidemic patterns of HFRS is related to the change of epidemic sources by the differences in urbanization between the two places.
ABSTRACT
ObjectiveTo investigate the pain relieving degree and the comprehensive efficacy of pricking-cupping bloodletting plus microwave therapy in treating intractable tennis elbow.MethodSeventy-two patients meeting the inclusion criteria were randomly allocated, using a random number table, to a treatment group (pricking-cupping bloodletting plus microwave therapy,n=36) and a control group (electroacupuncture plus microwave therapy,n=36). The pain relieving degree and the overall therapeutic effect were assessed using the Visual Analogue Scale (VAS) and theCriteria of Syndrome Diagnosis and Therapeutic Effect in Traditional Chinese Medicinein the patients after treatment.ResultThe pain relieving degree and the overall therapeutic effect were more remarkable in the treatment group than in the control group (P<0.05).ConclusionPricking-cupping bloodletting plus microwave therapy can effectively heighten the pain relieving degree and the overall therapeutic effect in treating patients with intractable tennis elbow.
