RESUMO
Objective:To analyze the causes of death of elderly inpatients,so as to provide direction for the precaution of geriatrics.Methods:The first page data of hospitalized medical records of elderly inpatients in medical department in the Second Hospital of Dalian Medical University from 2102 to 2019 were extracted, and the causes of death were analyzed. The statistical analysis was performed by Excel and SPSS 21.0 statistical software.Results:The number of deaths of elderly inpatients in medical department from 2012 to 2019 was 5 249. The proportion of deaths in ICU was 34.43%(1 807/5 249), in oncology department was19.03%(999/5 249), and in cardiovascular department was12.08%(634/5 249). The average age was (78.52 ± 7.82) years. Besides, the age of men was younger than women: (78.18 ± 8.00) years vs. (79.02 ± 7.52) years, and the differences was statistically significant ( P<0.01). Men(59.1%, 3 099/5 249) were more than women (40.96%, 2 150/5 249). The largest number of deaths was in the age of 75-84 years (42.56%, 2 234/5 249). The number of cases with combined above five diseases was 4 552(86.72%, 4 552/5 249). The top three causes of deaths of elderly inpatients in medical department from 2012 to 2019 were cardiocerebrovascular diseases (27.21%, 1 428/5 249), malignant tumor (25.74%, 1351/5 249) and respiratory system diseases (22.10%, 1160/5 249). From 2012 to 2015, the top three causes of deaths were malignant tumor, cardiocerebrovascular diseases and respiratorysystem diseases. From 2016 to 2019,the top three causes of deaths were cardiocerebrovascular diseases, malignant tumor, and respiratory system diseases. The most common cause in cardiocerebrovascular diseases of death was coronary heart disease (51.47%,735/1 428), cerebrovascular disease (43.70%,624/1 428),and hypertension(4.34%, 62/1 428). Among the patients with malignant tumor death, first cause of death waslung malignant tumor (37.53%, 507/1 351), the others in turn were gastric carcinoma (11.10%,150/1 351) and intestinal cancer (11.10%,150/1 351). Among the patients with respiratory system diseases, first cause of death was pulmonary infection (69.66%,808/1 160), the others in turn were chronic obstructive pulmonary disease (15.43%, 179/1 160) and interstitial lung disease (5.09%, 59/1 160). Conclusions:The average age of elderly inpatients in medical department is (78.52 ± 7.82) years. The death age of male is less than that of female, and the number is slightly more than that of female. The top three causes of deaths of elderly inpatients in medical department are cardiocerebrovascular diseases, malignant tumor, respiratorysystem diseases. From 2012 to 2015 the first cause of deaths is malignant tumor. From 2016 to 2019, the cardiocerebrovascular diseases rise to the first.
RESUMO
Objective:To study the diagnosis and treatment of osteoporotic fractures in the elderly in two third Grade A hospitals in Shenyang and Dalian, and to provide scientific basis for prevention and treatment of osteoporotic fractures in Dalian and Shenyang.Methods:Patients of osteoporotic fractures over 60 years old from January 2015 to December 2015 in the Second Hospital of Dalian Medical University and the People′s Hospital of Liaoning Province were chosen, and the basic characteristics, fracture site, the number of fracture site, diagnosis treatment and secondary prevention of osteoporosis fractures of them were analyzed.Results:Among the patients of osteoporotic fractures over 60 years old in the hospitals of Shenyang and Dalian, women were more than men ( P = 0.00). The predilection sites of elderly osteoporotic fractures in two hospitals were both followed by the hip, spine, ulnar and radial distal, proximal humerus. The rates respectively were 38.26%(295/771), 34.63% (267/771), 9.34%(72/771), 5.71%(44/771). The rate of fracture-again was 10.89%(84/771). The rates of in-hospital diagnosis, in-hospital treatment and treatment of discharged medical advice among osteoporosis were 13.88%(107/771), 24.64%(190/771) and 18.81%(145/771). There were 0.65% (5/771) patients who had diagnosis of osteoporosis, basic osteoporosis treatment (vitamin D 3 and calcium) and anti-osteoporosis treatment in both in-hospital and discharged medical advice. Conclusions:The rates of in-hospital diagnosis, in-hospital osteoporosis treatment and anti-osteoporosis treatment in discharged medical advice are both very low in the two third Grade A hospitals. The secondary prevention of osteoporosis fractures in the elderly has not been taken attention, and the situation of prevention and treatment are serious.
RESUMO
Objective To investigate the characteristics of growth and angiogenesis of colon cancer xenograft in nude mice with metabolic syndrome induced by high fat diet.Methods Female BALB/C nude mice were fed with high fat diet (45.0％ from fat,HFD group) or common diet (13.8％ from fat,CD group) for 12 weeks (n=15,respectively).Colon cancer cell line SW480 was marked with green fluorescent protein (GFP) and subcutaneous xenograft model was established.The tumor growth was observed by the in vivo imaging system in small animal at the 4th week.By the end of the experiment,serum glucose and lipid level of the two groups were measured,visceral subcutaneous and visceral adipose tissue,liver and xenograft tumor were dissociated and weighted.The differences of proliferating cell nuclear antigen (PCNA) and CD31 expression in the tumors between groups were analyzed.The t-test or x2 test were performed for group comparison.Results Compared with CD group,the body weight,blood serum glucose level,triglyceride and cholesterol level,adipose content of subcutaneous and visceral of the HFD group significantly increased (t=2.91,4.12,4.43,3.92,3.77 and 4.02,all P＜0.05).Averagedaily energy intake of HFD group was significantly higher than that of CD group (t=2.34,P＜0.05).There was no significant difference between the two groups in liver weight (t=1.02,P＞0.05).However,by HE staining lipid vacuoles in the liver tissue was obvious in HFD group.Average bioluminescent index,tumor volume and weight of xenografts of HFD group were remarkably higher than those of CD group (t=8.84,2.48 and 2.86,all P＜0.05).The immunohistochemical staining results indicated that the strong positive rate of PCNA in xenografts of HFD group was 80.00％ and the microvessel density (MVD) was (25.75±0.96)/per high power field,both of which were higher than those of CD group (14.29％ and (13.33±1.53)/per high power field respectively,x2 =12.52,t=13.35,both P＜0.01).Conclusions The colon cancer xenograft in nude mice with metabolic syndrome induced by high fat diet had a high MVD and grew fast.
