Prevalence of mild visual impairment in type 2 diabetes patients over 50 years old in Funing County: Jiangsu Diabetic Eye Disease Study / 中华实验眼科杂志

Objective:To investigate the prevalence and influencing factors of mild visual impairment in type 2 diabetic patients aged ≥50 years living in Funing County, Jiangsu Province.Methods:A population-based cross-sectional study was adopted.Cluster sampling was conducted among diabetic patients aged ≥50 years registered in the Chronic Disease Information Center of Funing County Center for Disease Prevention and Control from March 7th to April 20th, 2019.General information of selected patients was collected.Visual and ocular examinations on site were performed by ophthalmologists and technicians.The International Council of Ophthalmology standard for mild visual impairment, 0.3≤best corrected visual acuity<0.8 was adopted.The influencing factors of mild visual impairment were analyzed by logistic regression.This study protocol was approved by the Ethics Committee of Affiliated Hospital of Nantong University (No.2014-071).Results:Among the included 2 067 patients, 1 909 cases completed the investigation, with a response rate of 92.4%.There were 1 146 patients with mild visual impairment in at least one eye, and the prevalence of mild visual impairment was 60.00%.Among the eyes examined, 1 832 eyes were with mild visual impairment, accounting for 47.98%.Cataract (896/1 632), refractive error (515/1 632) and diabetic retinopathy (166/1 632) were the main causes of mild visual impairment in diabetic patients, accounting for 54.90%, 31.61% and 10.19%, respectively.Aging, female gender, low educational attainment, oral hypoglycemic drugs or subcutaneous insulin injection were risk factors for mild visual impairment in both eyes.Higher educational attainment, more sunshine exposure and exercise were protective factors for mild visual impairment in both eyes.Conclusions:The prevalence of mild visual impairment is relatively high in type 2 diabetic patients.Cataract surgery, correction of refractive error may help to improve mild visual impairment.Strengthening blood glucose control, more physical exercise and outdoor activities may slow the progression of mild visual impairment and prevent it from moderate and severe visual impairment.

Effect of traditional Chinese medicine comprehensive nursing on senile patients with coronary heart disease and constipation of qi stagnation and blood stasis type / 中国实用护理杂志

Objective:To explore the application effect of traditional Chinese medicine comprehensive nursing on elderly patients with coronary heart disease(qi stagnation and blood stasis type) constipation.Methods:A total of 126 elderly patients with coronary heart disease (qi stagnation and blood stasis type) constipation were divided into the control group and the experimental group by random digits table method, 63 cases each; the control group received routine nursing, and the experimental group was given traditional Chinese medicine comprehensive nursing; comparing the two groups of patients defecation, mental state, recurrence rate, and nursing satisfaction.Results:There was no significant difference in defecation frequency, each defecation time, defecation smoothness score, fecal trait score, fall inflated score, and self-Rating Anxiety Scale (SAS) score( P >0.05). After one month of nursing, defecation frequency, each defecation time, defecation smoothness score, fecal trait score, fall inflated score, and SAS score were (4.09±0.86) times/week, (5.12±1.24) min/time, (2.57±0.39) points, (1.53±0.31) points, (0.97±0.21) points, (49.27±4.15)points in the experimental group, (3.12±0.61) times/week, (6.87±1.52) min/time, (2.59±0.36) points, (2.02±0.44) points, (1.29±0.27) points, (54.42±6.01) points in the control group, the differences were significant ( t values were -6.638-7.081, all P<0.05). Within 1 month after nursing, the recurrence rate of constipation in the experimental group (14.3%, 9/63) was lower than that in the control group (74.6%, 47/63) , and the satisfaction rate of the experimental group (98.4%, 62/63) was higher than that in the control group (69.8%, 44/63) , the differences were significant(× 2 values were 46.414, 19.257, P<0.05). Conclusions:Traditional Chinese medicine comprehensive care for elderly patients with coronary heart disease (qi stagnation and blood stasis type) constipation can significantly improve their defecation and psychological state, and can reduce the recurrence rate and improve the patient's satisfaction with nursing, which deserves further clinical application and research.

Effect of psychological intervention combined with clopidogrel and Aspirin Enteric-coated Tablets on angina pectoris of coronary heart disease / 中国生化药物杂志

Objective To study the effects of combination therapy (psychological intervention+clopidogrel+aspirin) for coronary heart disease. Methods 88 cases were selected from January 2016 to April 2017 in patients with coronary heart disease in our hospital. In a randomized approach, patients were divided into treatment groups and control groups, with 44 cases per patient. Patients in the control group were treated with aspirin, and the treatment group was treated with a combination therapy (psychological intervention+clopidogrel+aspirin). The treatment effect, angina and adverse reaction were observed and compared.
