ObjectiveTo explore the risk factors for accompanying depression in patients with community type Ⅱ diabetes and to construct their risk prediction model. MethodsA total of 269 patients with type Ⅱ diabetes accompanied with depression and 217 patients with simple type Ⅱ diabetes from three community health service centers in two streets of Pingshan District, Shenzhen from October 2021 to April 2022 were included. The risk factors were analyzed and screened out, and a logistic regression risk prediction model was constructed. The goodness of fit and prediction ability of the model were tested by the Hosmer-Lemeshow test and the receiver operating characteristic (ROC) curve. Finally, the model was verified. ResultsLogistic regression analysis showed that smoking, diabetes complications, physical function, psychological dimension, medical coping for face, and medical coping for avoidance were independent risk factors for depressive disorder in patients with type Ⅱ diabetes. Modeling group Hosmer-Lemeshow test P=0.345, the area under the ROC curve was 0.987, sensitivity was 95.2% and specificity was 98.6%. The area under the ROC curve was 0.945, sensitivity was 89.8%, specificity was 84.8%, and accuracy was 86.8%, showing the model predictive value. ConclusionThe risk prediction model of type Ⅱ diabetes patients with depressive disorder constructed in this study has good predictive and discriminating ability.
Objectives To evaluate the risk factors of nonarteritic a nterior ischemic optic neuropathy（NAION）in a population of China and to provide theory basis for clinical decision. Methods Demographic features and clinical data of NAION were recorded. Cerebral infarction (CI) patients were also collected as control group. Systemic evaluations including whole blood chemical test, brain MRI, carotid artery ultrasound and fundus photography were perfor med in NAION and CI patients. The fundus photography and cup/disk ratio were als o acquired in a healthy controlgroup with matched age and gender. Statistical a nalysis was done by SPSS11.5 software. Results Thirtyeight N AION patients and 40 CI patients with intact data were included. Fundus photography and cup/disk ratio were acquired in 41 healthy individuals. No statistically significant difference regard to incidences of diabetes, male gender and lipid metabolic abnormalities was found between NAION and CI patients (Pgt;0.05). H ypertension, clinical and subclinical cerebral vascular disease and carotid ar tery stenosis were statistically more commonin CI patients than in NAION patien ts (Plt;0.01, 0.05). Cup/disk ratio was statistically significant smaller in NAION than in CI patients while no statistical difference (Pgt;0.05) was fo und between the CI group and healthy individuals. Conclusions NAION shared similar risk factors with cerebral infarction, but exposure of these risk factors was different between NAION and cerebral infarction. Hypertension , cerebral vascular disease and carotid artery stenosis were more common in cere bral infarction while diabetes, male gender and lipid metabolic abnormalities were similar. Small cup/disk ratio was an independent and the most important risk factor for NAION. (Chin J Ocul Fundus Dis,2008,24:86-89)

Meta-anlalysis revealed cigarettes comsuption per day, smoking duration, total amount of cigarettes ( pack-years) , smoking behaviour( depth) , initial age of smoking and duration of quitting smoking can increase the risk of lung cancer.
目的:探讨老老年患者颈动脉中层厚度(IMT)及其相关危险因素的关系,为老老年患者心脑血管疾病的预防及治疗提供临床参考。方法:根据年龄将139例老老年患者纳入分析,有血糖、血压、血脂代谢紊乱的123例作为观察组,无血糖、血压、血脂代谢紊乱的16例作为对照组,分别进行颈动脉超声检查、动态血压监测、糖化血红蛋白及血脂等生化指标检查,并结合临床资料进行分析。结果: 老老年患者均无一例外地存在着IMT增厚,在相同的年龄情况下,吸烟史、血脂紊乱、糖调节异常、血管炎症反应与IMT的增厚呈正相关,各组未显示出统计学差异,IMT的发生发展与年龄、性别、吸烟史、血糖、血压控制水平及血脂紊乱等因素在两组对照中均未显示出统计学差异,多因素Logistic回归分析,显示年龄、吸烟史及病程为危险因素(OR为0500～1196)。结论:老老年患者均不同程度地存在着IMT增厚,其中增龄是其最主要的危险因素,但是对合并有血糖、血压、血脂代谢紊乱的老老年患者也应该积极重视对各种危险因素的筛选和干预,特别在疾病发生发展的早期可能对延缓病变的进展和减少心脑血管事件有一定意义,可是其用药的安全性在该类患者就显得尤为重要。
ObjectiveBy comparing the epidemiological characteristics of the incidence and death of female breast cancer in China and the United States, the differences in prevention and screening strategies between China and the United States were analyzed to explore the prevention and control measures of female breast cancer in China. MethodsBased on the relevant data released by the Global Burden of Disease in 2020, the National Cancer Center of China, and the China Health Statistical Yearbook, the new cases and deaths of breast cancer in Chinese and American women in 2023 were estimated respectively, and the incidence, mortality and time trend of breast cancer in Chinese and American women were analyzed. ResultsIn China, 376 789 new cases of female breast cancer and 116 791 deaths were expected in 2023. In the United States, approximately 297 790 women were expected to be newly diagnosed with breast cancer in 2023, representing approximately 15.2% of new cancer cases. About 43 170 women died from breast cancer, accounting for about 7.1% of all cancer deaths. The incidence of breast cancer in women in the United States during the period 1975–2020 gradually increased and then stabilized; In contrast, the incidence of breast cancer among Chinese women increased year by year during the period 1990–2020. In recent years, the incidence and mortality rates of breast cancer in Chinese women had increased more than those in the United States, and there was a large difference between urban and rural areas in China. ConclusionsBoth China and the United States face a large burden of female breast cancer, and the characteristics of female breast cancer in China are similar to those in the United States. To reduce the burden of breast cancer in Chinese women, further efforts should be made in various aspects, such as strengthening breast cancer education, raising public health awareness, improving diet structure, cultivating healthy lifestyle, increasing screening efforts, and improving medical level.
Objective To observe and analyze the risk factors of secondary intraocular hypertension in diabetic macular edema (DME) patients after treatment with dexamethasone vitreous cavity implant (DEX). MethodsA retrospective observational study. A total of 352 patients with type 2 diabetes mellitus (T2DM) secondary macular edema diagnosed by ophthalmic examination and treated with DEX in Department of Ophthalmology of Harbin 242 Hospital from January 2016 to March 2022 were included in the study. Among them, 221 were males and 131 were females, with the mean age of (55.56±8.09) years. There were 194 patients with disseminated macular edema, 158 patients with cystoid macular edema. All patients underwent vitreous cavity implantation of DEX. Intraocular pressure (IOP) was measured once a month for 3 months after treatment, with IOP over than 25 mm Hg (1 mm Hg=0.133 kPa) or higher than 10 mm Hg from baseline as secondary intraocular hypertension. The relevant clinical data were collected, and the risk factors of secondary intraocular hypertension in DME patients after DEX treatment were analyzed by binary logistic regression. ResultsAmong 352 patients, 116 patients (32.95%, 116/352) were in the intraocular hypertension. Among them, 29 patients (25.00%, 29/116), 69 patients (59.48%, 69/116) and 18 patients (15.52%, 18/116) occurred intraocular hypertension at 1, 2 and 3 months after treatment, respectively. Compared with the normal IOP group, the IOP in the intraocular hypertension group increased significantly at 1, 2 and 3 months after treatment, with statistical significance (t=10.771, 21.116, 13.761; P＜0.001). Compared with normal IOP group, the patients in the intraocular hypertension group had younger age (t=6.967), longer duration of diabetes (t=5.950), longer axial length (AL) (t=14.989), higher proportion of DME grade 3 (Z=6.284), higher proportion of DEX implantation in pars plana (χ2=23.275), and higher HbA1c level (t=10.764), the differences were statistically significant (P＜0.05). Logistic regression analysis showed that longer AL [odds ratio (OR)=1.428, 95% confidence interval (CI) 1.054-1.934], DEX implantation in pars plana (OR=1.358, 95%CI 1.063-1.735), and higher HbA1c (OR=1.702, 95%CI 1.225-2.366) were the risk factors for secondary intraocular hypertension in DME patients after DEX treatment (P＜0.05), older age was a protective factor (OR=0.548, 95%CI 0.380-0.789, P＜0.05). ConclusionsLong AL, DEX implantation in pars plana and high HbA1c are the risk factors for secondary intraocular hypertension after DEX treatment in DME patients, older age is a protective factor.
ObjectiveTo analyze the effect of carotid artery stenosis degree and intervention for carotid artery stenosis on the incidence of central nervous system complications after off-pump coronary artery bypass grafting (OPCABG) and explore the influencing factors. MethodsA total of 1 150 patients undergoing OPCABG in our hospital from June 2018 to June 2021 were selected and divided into two groups according to whether there were central nervous system complications, including a central nervous system complication group [n=61, 43 males and 18 females with a median age of 68.0 (63.0, 74.0) years] and a non-central nervous system complication group [n=1 089, 796 males and 293 females with a median age of 65.5 (59.0, 70.0) years]. The risk factors for central nervous system complications after OPCABG were analyzed. ResultsUnivariate analysis showed that age, smoking, hyperlipidemia, preoperative left ventricular ejection fraction, intra-aortic ballon pump (IABP), postoperative arrhythmia, postoperative thoracotomy and blood transfusion volume were associated with central nervous system complications. The incidence of central nervous system complications in patients with severe carotid artery stenosis or occlusion (11.63%) was higher than that in the non-stenosis and mild stenosis patients (4.80%) and moderate stenosis patients (4.76%) with a statistical difference (P=0.038). The intervention for carotid artery stenosis before or during the operation did not reduce the incidence of central nervous system complications after the operation (42.11% vs. 2.99%, P<0.001). Age, postoperative arrhythmia, severe unilateral or bilateral carotid artery stenosis and occlusion were independent risk factors for postoperative central nervous system complications (P<0.05). Conclusion The age, smoking, hyperlipidemia, preoperative left ventricular ejection fraction, intraoperative use of IABP, postoperative arrhythmia, secondary thoracotomy after surgery, blood transfusion volume and OPCABG are associated with the incidence of postoperative central nervous system complications in patients. Age, postoperative arrhythmia, severe unilateral or bilateral carotid artery stenosis and occlusion are independent risk factors for postoperative central nervous system complications. In patients with severe carotid artery stenosis, preoperative treatment of the carotid artery will not reduce the incidence of central nervous system complications.
Objective To describe the development trend of clinical symptoms, pulmonary function and chest imaging examination of COVID-19 discharged from Xinyang from January 2020 to June 2020, and analyze the related risk factors. Methods This study was a prospective, longitudinal and cohort study. The survivors of COVID-19 hospitalized in Xinyang Fifth People's Hospital and Xinyang Central Hospital from January to June, 2020 were prospectively followed up 12 months and 24 months after discharge. Patients who refused to participate in the study and suffered from cancer and chronic respiratory diseases, including asthma or chronic obstructive pulmonary disease, were excluded. During the follow-up period, the patients who meet the research conditions were asked about clinical symptoms, routine and biochemical blood tests, pulmonary function and chest high-resolution CT (HRCT) and 6-minute walking distance test, and were evaluated with the Dyspnea Scale (mMRC). Results It was found that from January to June, 2020, among 207 eligible patients, 169 patients participated in this study, including 126 cases of mild and ordinary type (74.6%) and 43 cases of severe and critical type (25.4%). There were 100 males (59.2%) and 69 females (40.8%), aged 20 - 78 years old (50±15). It was found that more than half of COVID-19 patients had one or more symptoms at the end of 12 months after rehabilitation, including fatigue (90 cases, 53.3%), insomnia (43 cases, 25.4%), anxiety (24 cases, 14.2%), chest tightness (29 cases, 17.2%) and alopecia (35 cases, 20.7%). Two years after discharge, 52 patients (30.8%) still had at least one clinical symptom. The quality of life, cardiopulmonary function and exercise ability of COVID-19 patients in rehabilitation period decreased to varying degrees. Most patients' lung function and CT results returned to normal, but a few patients still had persistent lung function and imaging abnormalities 12 months and 24 months after discharge. Pulmonary function was mainly manifested as diffuse function injury, and the predicted value of carbon monoxide diffusion capacity (DLCO) was less than 80% in 44 cases (26.0%). Pulmonary HRCT mainly showed chronic inflammation in one lung/both lungs (28 cases, 41.2%), multiple nodules in one lung/both lungs (23 cases, 33.8%) and ground glass shadow (10 cases, 14.7%), etc. Multivariate logistic regression analysis showed that female COVID-19 patients with old age were more likely to have anxiety symptoms after discharge, which had nothing to do with the severity of acute disease. Older female patients with severe COVID-19 were more likely to have symptoms of DLCO damage during the recovery period, and their lung function gradually recovered with time. Conclusions Most of COVID-19 patients in Xinyang recovered well during the rehabilitation period, but some patients still had clinical symptoms such as fatigue, insomnia, anxiety, etc. The absorption of lung lesions was slow and some patients were accompanied by impaired pulmonary diffusion function. With the extension of rehabilitation time, the above symptoms have been significantly improved.
