Objective To investigate the prevalence and related factors of diabetic retinopathy (DR) among residents with type 2 diabetes mellitus (T2DM) in Culai Town of Tai'an City in Shandong Province. Methods According to the DM management file database for community, 785 patients with T2DM were randomly selected by cluster sampling method. The questionnaires, routine general examinations, visual and fundus-free fluoroscopy were performed on all the patients. DR diagnosis and classification was according to the guidelines for clinical diagnosis and treatment of DR in China (2014). Both monocular and binocular DR were selected as DR patients, and the worse eye for binocular DR were treated as the DR classification of the patient. The patients were grouped by presence or absence of DR. GraphPad Prism 6, SigmaPlot 12.5, SPSS 20.0 and Excel were used to achieve data analysis. Also, SPSS 20.0 was used for multi-factor logistic regression analysis. Results A total of 699 patients (89.04%) were actually recorded. There were 122 eyes of 63 patients (9.01%) with DR (DR group), 1272 eyes of 636 patients (90.99%) without DR (NDR group). Among the 122 eyes of DR, there were 19 (15.57%), 17 (13.93%), 70 (57.38%), 10 (8.20%), 6 (4.92%) eyes in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, respectively. The differences of mean age (t=15 290, P=0.002), DM duration (t=9075, P＜0.000) and diastolic blood pressure (t=15 810, P=0.006) between the two groups were statistically significant. There were 23 (36.51%) and 394 (61.95%) patients with hypertension history in the DR group and the NDR group, with the significant difference ( χ2=15.42, OR=0.35, 95%CI 0.21-0.60). There were 57 (90.48%) and 500 (78.62%) patients with fasting blood glucose larger than 6.11 mmol/L in the DR group and the NDR group, with the significant difference (OR=2.51, 95%CI 1.06-5.95, P=0.031). Logistic regression analysis showed that the age, fasting blood glucose and DM duration were influencing factors for DR (OR=1.039, 0.864, 0.898; P=0.021, ＜0.000, ＜0.000). Conclusion The prevalence of DR in patients with T2DM in Culai Town of Tai'an City is 9.01%. Age, DM duration, fasting blood glucose are associated to DR. Those with a history of hypertension may have a lower risk of DR than those without a history of hypertension.
ObjectiveTo investigate the prevalence of thyroid nodules and its influencing factors among medical staff of a hospital in Hengshui. MethodsA total of 2 190 medical workers in a hospital in Hengshui who underwent physical examinations in the Medical Examination Center of Harrison International Peace Hospital from January 2012 to July 2013 were included as the study subjects. Through physical examination, thyroid ultrasonography and questionnaire, we collected data and investigated the prevalence of thyroid nodules and its influencing factors. ResultsThe prevalence rate of thyroid nodules was 39.45% (864/2 190) in these medical staff. The prevalence rates of thyroid nodules in males and females were 32.34% (238/736) and 42.92% (624/1 454), respectively, with statistically significant difference between them (χ2=22.913, P<0.001). With increasing age, the prevalence of thyroid nodules increased gradually, and the prevalence of the same sex increased gradually too (P<0.001). The prevalence rate of women was significantly higher than that of men for each age group (P<0.05). Among the 864 subjects, there were 550 (63.66%) with multiple nodules and 314 (36.34%) with solitary nodules; there were 454 (52.55%) with nodules in both lobes of thyroid, 238 (27.54%) with nodules in the right lobe of thyroid, and 172 (19.91%) with nodules in the left lobe of thyroid; there were 504 (58.33%) with solid modules, 172 (19.91%) with cystic nodules, 114 (13.19%) with solid and cystic nodules, and 74 (8.56%) with calcification. Logistic regression analysis showed that gender, age, educational degree, drinking history, taste habit, stress, agitation were correlated with the development of thyroid nodules. ConclusionThe prevalence of thyroid nodules is high among medical staff of this hospital. Thyroid nodules can be prevented through healthy lifestyle, limiting alcohol intake, emotional control, and relieving stress. Early diagnosis and early treatment should be done to prevent the development and spread of thyroid nodules.
Objective To study the prevalence of combined pulmonary fibrosis and emphysema (CPFE) in a community-based lung cancer screening program in Shanghai. Methods From June 2018 to July 2019, eligible participants who were assessed through a high-risk lung cancer questionnaire in Xuhui, Shanghai underwent low-dose computed tomography of the lungs. The suspected CPFE patients were invited to provide medical history and blood for analysis, and received high-resolution CT (HRCT) scanning for confirmation. Results Of the 15 cases of suspected CPFE from a total of 4478 participants in which 1704 males and 2774 females, 4 declined further examination and 11 received further examine. Eight subjects were confirmed as CPFE, and all were male, of whom two were ex-smokers and six were active smokers. These CPFE patients had cough, chest tightness and dyspnea. There were 3 cases of centrilobular emphysema, 2 cases of paraseptal emphysema, 1 case of panlobular emphysema and 2 cases of mixed emphysema. There were 2 cases of usual interstitial pneumonia, 3 cases of non-specific interstitial pneumonia, 2 cases of airspace enlargement with fibrosis and 1 case of unclassifiable smoking-related interstitial fibrosis. The KBILD scores were 61.7±7.5 and mMRC scores were 1.5±0.8. Serum Krebs von den Lungen-6 concentration was (380.75±212.05)U/mL. Lung function test showed normal or mild restrictive ventilatory function, and mild-moderate impairment in diffusion capacity. Conclusions The prevalence of CPFE is 1.79‰ in a community-based lung cancer screening population, and is 4.69‰ in male lung cancer screening population.

Objective To analyze the prevalence and influencing factors of dyslipidemia among permanent residents in Longquanyi district of Chengdu for prevention and control of dyslipidemia. Methods Permanent residents in Longquanyi district were selected as research objects by convenient sampling method between November 2021 and February 2022. The dyslipidemia rate in the population was analyzed, and the influencing factors of dyslipidemia were analyzed by univariate and multivariate logistic regression. Results A total of 11 408 permanent residents were included. Among them, 3650 people had dyslipidemia, with a prevalence rate of 32.00% (3650/11408). The prevalence rates of high total cholesterol, high triglyceride, high low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol were 19.30% (2 202/11 408), 13.38% (1 526/11 408), 5.05% (576/11 408) and 0.73% (83/11 408), respectively. Multivariate logistic regression analysis showed that female, age≥30 years old, drinking, overweight / obesity, hypertension, diabetes and hyperuricemia were independent risk factors of dyslipidemia among permanent residents (P<0.05). Conclusions The prevalence of dyslipidemia in Longquanyi district is high, mainly with high total cholesterol and high triglyceride. Gender, age, drinking, body mass index, and the levels of blood pressure, blood glucose and blood uric acid are the factors affecting the incidence of dyslipidemia among permanent residents. Early intervention for high-risk groups with dyslipidemia should be adopted to effectively reduce the risk and burden of dyslipidemia.
