目的:心房纖顫是老年最常見的心律失常之一,并且帶來了如外周血管血栓形成、肺梗死、腦卒中等并發癥。口服抗凝治療是預防該類并發癥的有效手段,但監測繁瑣、有藥物不良反應風險等。本實驗為尋找有效的房顫管理模式,設計了社區管理模式,并與專科管理模式進行對照,以研究社區管理模式是否適合老年房顫患者的管理。方法:納入在我院就診的老年房顫患者107名,隨機分入社區管理組及專科管理組,其中專科管理組患者在珠海市人民醫院門診常規就診,而社區管理組在所屬社區進行治療。對照比較在抗凝達標率、華法林相關不良反應事件發生率(出血、血栓事件)、及費用方面的差異。結果:與專科管理組比較,社區管理組在抗凝達標率(分別為612%,642%,Pgt;005)、出血及血栓事件(P值分別為0133,0279)發生率方面無明顯統計學差異,但是在總體費用方面存在著統計學差異(Plt;0001)。結論:老年房顫患者華法林抗凝治療在社區管理有著與專科管理相似的可行性、安全性及有效性,并且有費用方面的優勢。
Objective To determine the safety and efficacy of surgical biliary bypass on the elderly patients with unresectable pancreatic head cancer. Methods The clinical data of 55 cases with unresectable pancreatic head cancer treated with palliation methods from July 2002 to June 2009 in our hospital were retrospectively analyzed. The patients were divided into three groups according to different age and therapeutic program: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (group A), 19 patients under 65 years of age were treated by surgical biliary bypass (group B) and 17 patients with the age of 65 years or older received percutaneous transhepatic biliary drainage (group C). Then the therapeutic results were compared.Results With respect to the postoperative level of serum bilirubin, the incidence of early complications, postoperative hospitalization and mean survival time, no statistically significant difference was found between group A and B (Pgt;0.05). There was one case of recurrent jaundice and one case of gastric output obstruction in group B, while no one suffered postoperative complication in group A, and the difference was statistically significant (Plt;0.01). Compared with group A, the postoperative level of serum bilirubin, the number of patient readmitted, the rate of recurrent jaundice and gastric output obstruction were higher in group C (Plt;0.05 or Plt;0.01). The mean postoperative hospitalization and overall survival time were significantly shorter in group C than group A (Plt;0.05 or Plt;0.01, respectively). Conclusion Surgical palliation does not increase the morbidity rate, but it does improve the quality of life in elderly patients with unresectable pancreatic head cancer.
Objective To define risk factors of nosocomical pneumonia (NP) in elderly in-patients. Methods Two hundred elderly in-patients were selected in the Geriatric Department of West China Hospital from January 1999 to June 2002. Among them, 100 patients developed NP during their hospital days and the others didn’t have the episodes of NP at the same time. The following factors were analyzed: sex, age, multiple underline diseases and their severity, smoking, activity of daily life, conscious status, aspiration, nasogastrial intubations, antibiotics use and hospitalization. SPSS 10.0 was used for Logistic regression analysis to determine the factors significantly associated with the development of NP. Results The following factors were significantly associated with the development of NP in the logistic regression analysis: aspiration [OR 28.452, 95%CI (3.793 to 213.447)],multiple diseases [OR 17.157, 95%CI (2.734 to 107.651)], multiple antibiotics use [OR 6.396, 95%CI (1.861 to 21.980)], smoking [OR 1.774, 95%CI (1.211 to 2.600)] and prolonged hospitalization [OR 1.134, 95%CI (1.081 to 1.189)]. Conclusions Aspiration, multiple diseases, multiple antitiotics use, smoking and prolonged hospitalization are closely related to NP in elderly in-patients. Cautionary medical measures and shortening hospitalization were the key factors to decrease the incidence of NP for the patients in Geriatric Department.
Objective To understand the frailty status and main influencing factors of elderly Parkinson’s disease (PD) patients. Methods The elderly PD patients who attended the Department of Neurology of Changshu Hospital of Traditional Chinese Medicine between November 2023 and March 2024 were selected. The patients’ frailty conditions were investigated using general information questionnaire, Chinese version of Tilburg Frailty Indicator, Hoehn-Yahr Rating Scale, Mini-Nutritional Assessment Short Form, Movement Disorder Society-Unified PD Rating Scale Part Ⅲ, PD Sleep Scale-2, and Mini-Mental State Examination. Multiple linear regression analysis was used to further determine the influencing factors of the frailty status in elderly PD patients. Results A total of 170 PD patients were included. Among them, 117 cases (68.82%) had frailty, while 53 cases (31.18%) had not frailty. The average score for frailty was (6.48±3.34) points, the average score for nutritional status was (11.89±1.65) points, the average score for motor function was (27.40±13.73) points, the average score for sleep quality was (16.05±7.76) points, and the average score for cognitive status is (26.25±4.51) points. The Pearson correlation analysis results showed that PD patient frailty was positively correlated with motor function and sleep quality (P<0.01), and negatively correlated with nutritional status and cognitive status (P<0.01). The results of multiple linear regression analysis showed that age, education, place of residence, course of disease, Hoehn-Yahr Rating, nutritional status, motor function, cognitive status and sleep quality were the influencing factors of frailty in PD patients (P<0.05). Conclusions Elderly PD patients are prone to frailty. Healthcare professionals should pay attention to early screening for frailty in this population and provide timely and effective interventions to prevent or delay the onset of frailty in patients.

Objective To explore the effect of age and gene therapyon the differentiation of marrow mesenchymal stem cells （MSCs） of the rats. Methods MSCs from the young (1-month-old), adult (9-month-old), and the aged(24monthold) rats were expanded in culture and infected with adenovirus mediated human bone morphogenetic protein 2 gene (Ad-BMP-2). The expression of BMP-2 and osteoblastic markers such as alkaline phosphatase(ALP), collagen Ⅰ(Col Ⅰ), bone sialoprotein(BSP) and osteopontin(OPN) were assayed during the process of differentiation. Their abilities to induce ectopic bone formation in nude mice were also tested. Results There was no significant difference in the expression of BMP-2 among the 3 groups. ALP activity assay and semi-quantitative reverse transcription polymerase chain reaction(RT-PCR) demonstrated that there were no significant differences in the expression of osteoblastic markers ALP, Col-Ⅰ, OPN and BSP amongthe 3 groups. Histomorphometric analysis indicated that there were no significant differences in the volume of the newly formed ectopic bones in nude mice amongthe 3 groups. Conclusion MSCs obtained from the aged ratscan restore their osteogenic activity following human BMP-2 gene transduction, therefore provides an alternative to treating the aged bone disease.
ObjectiveTo explore the influence of sentinel lymph node (SLN) status on the prognosis of elderly breast cancer patients ≥70 years old, and to screen patients who may be exempted from sentinel lymph node biopsy (SLNB), so as to guide clinical individualized treatment for such patients. MethodsA retrospective analysis was made on 270 breast cancer patients aged ≥70 years old who underwent SLNB in the Affiliated Hospital of Southwest Medical University from 2012 to 2021. The clinicopathological characteristics of the total cases were compared according to the status of SLN. Kaplan-Meier method was used to draw the survival curve, and the influence of SLN status on the overall survival (OS) time, local recurrence (LR) and distant metastasis (DM) of patients were analyzed, and used log-rank to compare between groups. At the same time, the patients with hormone receptor (HR) positive were analyzed by subgroup. The differences between groups were compared by single factor χ2 test, and multivariate Cox regression model was used to analyze and determine the factors affecting OS, LR and DM of patients. ResultsThe age of 270 patients ranged from 70 to 95 years, with a median age of 74 years. One hundred and sixty-nine (62.6%) patients’ tumor were T2 stage. Invasive ductal carcinoma accounted for 83.0%, histological gradeⅡ accounted for 74.4%, estrogen receptor positive accounted for 78.1%, progesterone receptor positive accounted for 71.9%, and human epidermal growth factor receptor 2 negative accounted for 83.3%. The number of SLNs obtained by SLNB were 1-9, and the median was 3. SLN was negative in 202 cases (74.8%) and positive in 68 cases (25.2%). Thirty-five patients (13.0%) received axillary lymph node dissection. There was no significant difference in LR between the SLN positive group and the SLN negative group (P>0.05), but the SLN negative group had fewer occurrences of DM (P=0.001) and longer OS time (P=0.009) compared to the SLN positive group. The results of univariate and multivariate analysis suggest that the older the patient, the shorter the OS time and the greater the risk of DM. Analysis of HR positive subgroups showed that SLN status did not affect patient survival and prognosis, but age was still associated with poor OS time and DM. ConclusionsFor patients with invasive ductal carcinoma of breast in T1-T2 stage, HR positive, clinical axillary lymph nodes negative, and age ≥70 years old, SLNB may be exempted. According to the patient’s performance or tumor biological characteristics, patients who need systemic adjuvant chemotherapy may still consider SLNB.
