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.

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 analyze the correlation between frailty syndrome and lower limb motor function in hospitalized elderly patients. Methods Convenience sampling method was used to select inpatients aged 65 and above from the Center of Gerontology and Geriatrics of West China Hospital, Sichuan University between December 2022 and May 2023. The FRAIL Scale, Short Physical Performance Battery (SPPB), and Timed Up and Go Test (TUGT) were used to evaluate the degree of frailty and lower limb motor function, and to explore the correlation between frailty and lower limb motor function. Results A total of 501 elderly patients were included, including 325 males (64.9%) and 176 females (35.1%); 256 cases of frailty (51.1%), 161 cases of pre-frailty (32.1%), and 84 cases of non-frailty (16.8%). The incidence of frailty in hospitalized elderly male patients was higher than that in female patients (P<0.05); The incidence of frailty in patients aged 80-99 was higher than that in patients aged 65-79 (P<0.05). The Spearman correlation analysis results showed that all dimensions of SPPB were negatively correlated with frailty (P<0.001), while TUGT was positively correlated with frailty (r=0.776, P<0.001). The results of multiple linear regression analysis showed that the worse the motor function of the lower limbs, the higher the debilitation score. Conclusions Frailty syndrome in hospitalized elderly patients is closely related to lower limb motor function. Lower limb motor function assessment can be used to predict the onset of frailty in clinical practice, and interventions to improve lower limb motor function can be used to improve the frailty of elderly patients.
Objective To explore the impact of community healthcare workers’ (CHWs) knowledge, attitude and practice (KAP) on the influenza vaccination among elderly people. Methods By means of simple random sampling, 1 residential quarter of each communities, 2 communities of each districts, 5 districts of Chengdu city were randomly selected, and the elderly equal to or more than 60-year-old were on-site investigated. Meanwhile, the questionnaire survey was conducted among healthcare workers in the selected communities. Results There were 4 KAP factors played a positive role in influenza vaccination among elderly people: CHWs’ affirmation of the effectiveness of influenza vaccine, explicitly knowing the focus groups for influenza vaccination, recommendation of vaccination in flu season when the elderly visits, and participation in flu-related education activities. When the accuracy rate of each factor got improved by 1%, the influenza vaccination rate would improve by 2.747%, 1.299%, 0.864%, 0.602%, respectively. Conclusion The knowledge, attitude and practice of HCWs have impacts on the influenza vaccination rates of elderly people. They are significant to improve the influenza vaccination rates of the elderly.
