PURPOSE:To approach the changes of visual function by using the dense matrix mapping in macula(DMMM)in patients with age-related macular degenerationl(AMD). METHODS:The DMMM was designed using Humphrey-640,thee study included 51 patients(71 eyes)in dry type,AMD,23 patients(27 eyes)in wet type and 16 normal elderly(21 eyes). RESULTS:In 2.5 degree of macula:the mean light sensitivity(MLS)was 35.61plusmn;1.37 in normal elderly.33.30plusmn;2. 49 in dry type group and 20.67plusmn;8.30 in wet type group,and differences were highly significant statistically among them. In S degree the MLS is 34.93plusmn;1.46 in normal elderly.32.95plusmn;1.82 in dry type group, 22.11plusmn;7.74 in wet type group ,and the differences were highly significant statistically among them. CONCLUSIONS:The MLS of DMMM declined at early stage of dry type AMD and there was relatively high sensitivity of MLS of DMMM in evaluating the visual function in early AMD. （Chin J Ocul Fundus Dis,1996,12: 217-219 ）
Objective To assess safety and feasibility of laparoscopic gastrectomy in the elderly with gastric cancer. Methods From January 2010 to September 2014, 146 elderly (age ≥65 years old) patients with gastric cancer underwent radical operations in the Department of General Surgery, Guangdong Academy of Medical Sciences and Guangdong General Hospital were collected, then were divided into a laparoscopy-assisted radical gastrectomy (LAG group, n=40) and an open radical gastrectomy (OG group, n=106) according to the operative mode. The differences of intraoperative and postoperative situation, and the postoperative complications were analyzed between the LAG group and the OG group. Results ① The age, gender, body mass index, albumin, ASA grade, tumor location, differentiation degree, TNM stage, radical gastrectomy, and digestive tract anastomosis had no significant differences between the LAG group and the OG group (P>0.05). ② None of the patients died during the operative period and there was no significant difference in the mean number of retrieved lymph nodes between these two groups (P>0.05). In the aspects of the intraoperative blood loss, the first flatus time or the first feeding time, and the postoperative hospitalization stay in the LAG group were significantly less than those in the OG group (P<0.05). For the operative time, the OG group showed a distinctive advantage with a significantdifference than the LAG group (P<0.05). ③ The rate of postoperative complication in the LAG group and OG group was 10.0% (4/40) and 15.1% (16/106) respectively, and the difference was not significant (χ2=0.64, P=0.591), the grade of the Clavien-Dindo complications had no significant difference (χ2=0.63, P=0.592). ④ None of the patients died following operation in the LAG group and one case died in the OG group because of the respiratory and circulatory failure caused by the pulmonary embolism. Conclusion Preliminary results of limited cases in this study show that LAG in the elderly patients with gastric cancer could reduce intraoperative blood loss, shorten the first flatus time or the first feeding time, and postoperative hospitalization stay, could obtain same radical effect without increasing incidence of postoperative complications as compared with OG, so it is safety and feasible.

Objective To broaden the current understanding of the usage willingness about artificial intelligence (AI) robots and relevant influence factors for elderly patients. Methods The elderly patients in the inpatient ward, outpatient department and physical examination of the Department of Geriatrics, West China Hospital of Sichuan University were selected by convenient sampling for investigation between February and April 2020, to explore the willingness of elderly patients to use AI robots and related influencing factors. Results A total of 446 elderly patients were included. There were 244 males and 202 females. The willingness to use AI robots was (14.40±3.62) points. There were statistically significant differences among the elderly patients with different ages, marital status, living conditions, educational level, current health status, current vision status, current hearing status, self-care ability and family support in their willingness to use AI robots (P<0.05). Multiple linear regression analysis showed that age, education level and family support were the influencing factors of use intention (P<0.05). Among the elderly patients, 60.76% had heard of AI robots, but only 28.03% knew the medical application of AI robots, and only 13.90% had used AI robot services. Most elderly patients (>60%) thought that some adverse factors may reduce their usage willingness, like “the price is too expensive” and “the use is complex, or I don’t know how to use”. Conclusions Elderly patients’ cognition of AI robots is still at a low level, and their willingness to use AI robots is mainly affected by age, education level and family support. It is suggested to consider the personalized needs of the elderly in terms of different ages, education levels and family support, and promote the cheap and user-friendly AI robots, so as to improve the use of AI robots by elderly patients.
Objective To explore the expression levels and clinical significance of serum long noncoding RNA myocardial infarction associated transcript (lncRNA MIAT) and microRNA-515-5p (miR-515-5p) in elderly patients with chronic obstructive pulmonary disease (COPD) at different periods. Methods From April 2021 to June 2023, 90 elderly patients with acute exacerbation of COPD treated in Huaibei People’s Hospital were selected as a COPD acute exacerbation group, 88 elderly patients with stable COPD as a COPD stable group, and 90 healthy elderly individuals undergoing physical examination as a control group. The white blood cell count (WBC) and serum lncRNA MIAT and miR-515-5p expression levels were detected in all subjects, blood gas analysis and pulmonary function indexes [oxygenation index (PaO2/FiO2), arterial blood carbon dioxide partial pressure (PaCO2), ratio of forced expiratory volume in the first second to forced vital capacity (FEV1/FVC), and FEV1 as a percentage of predicted value (FEV1%pred)] were detected in the patients with COPD. The correlation between serum lncRNA MIAT, miR-515-5p and smoking, WBC, blood gas analysis and pulmonary function indexes were analyzed in the elderly patients with acute exacerbation of COPD. The influencing factors of acute exacerbation of COPD, and the value of serum lncRNA MIAT, miR-515-5p in predicting the occurrence of acute exacerbation of COPD were also analyzed. Results The smoking proportion, WBC, serum lncRNA MIAT expression levels of the control group, the COPD stable group and the COPD acute exacerbation group were increased in turn, serum miR-515-5p expression levels were decreased in turn (P<0.05). Compared with the COPD stable group, PaCO2 was significantly increased in the COPD acute exacerbation group, while PaO2/FiO2, FEV1/FVC and FEV1%pred were significantly decreased (P<0.05); serum lncRNA MIAT in the elderly patients with acute exacerbation of COPD was positively correlated with smoking, WBC, PaCO2 (P<0.05), and negatively correlated with PaO2/FiO2, FEV1/FVC, FEV1%pred, miR-515-5p (P<0.05); serum miR-515-5p was negatively correlated with smoking, WBC, PaCO2 (P<0.05), and positively correlated with PaO2/FiO2, FEV1/FVC, FEV1%pred (P<0.05). Smoking, WBC, PaCO2, and lncRNA MIAT were risk factors affecting the acute exacerbation of COPD patients, PaO2/FiO2, FEV1/FVC, FEV1%pred, miR-515-5p were protective factors affecting the acute exacerbation of elderly COPD patients (P<0.05). The area under the ROC curve (AUC) of serum lncRNA MIAT, miR-515-5p and their combination in predicting acute exacerbation in elderly COPD patients were 0.823, 0.862 and 0.919, respectively, higher than the AUC predicted by serum lncRNA MIAT and miR-515-5p separately (P<0.05). Conclusions Serum lncRNA MIAT expression was high in elderly patients with COPD, and serum miR-515-5p expression was low, and the changes of both were more obvious in patients with acute exacerbation. Both were correlated with blood gas analysis and pulmonary function indexes in patients with acute exacerbation, and have high value in predicting the occurrence of acute exacerbation in elderly patients with COPD.
ObjectiveTo observe the risk factors for osteoporosis in elderly women in Chengdu Shuangliu County, in order to provide a reference for the prevention of this disease. MethodsThrough random cluster sampling from 6 communities in Shuangliu County, 276 aged (60-84 years old) women accepted questionnaire survey from May 2010 to October 2012. Their bone mineral density was also measured. ResultsThe osteoporosis rate in these 276 elderly women was 49.64%. Different occupations had a significant impact on the occurrence of osteoporosis (P<0.05). Osteoporosis rate in elderly women in rural areas was higher than that in urban areas, but there was no significant difference (P>0.05). The rate of women who paid attention to calcium and vitamin D preparations was significantly lower than those with no supplement of calcium and vitamin D preparations (P<0.05). Single factor analysis showed that age, body mass index of age 30, present weight, menopause age, suffering from respiratory diseases were closely related to osteoporosis (P<0.05). Multivariate analysis showed that age, present weight, consumption of milk, menopause age, and respiratory disease history were closely correlated with osteoporosis incidence (P<0.05). ConclusionThe incidence of osteoporosis in women at age 60 or older in Chengdu Shuangliu County is high. Medical workers should strengthen the health education for those elderly women with osteoporosis and promote a healthy lifestyle and a balanced diet.
