Objective To explore the risk factors for peptic ulcer bleeding in elderly patients.Methods The 414 patients with upper gastrointestinal ulcer bleeding in Xuanwu Hospital from January 2001 to January 2006 were enrolled.The patients were divided into elderly group (≥ 60years,n= 183 ) and non-elderly group ( ＜ 60 years,n= 231 ).The coexisting diseases and hemorrhage causes were compared and analyzed.Results The detection rate of coexisting diseases was significantly higher in elderly group than in non-elderly group (68.9% vs.10.0% ).The hemorrhage causes included the taking of drugs for cardiovascular and cerebrovascular diseases or osteoarthropathy in elderly group.And the fatigue,stress and dietary upset were the main causes in non-elderly group.Helicobacter pylori infection rate was 35.0% in the elderly and 58.0% in young patients.Conclusions It is very important to promote rational use of anticoagulant drugs and analgesic agents in elderly patients for managing peptic ulcer complication.

Objective To analyze the influence of elderly dementia living in urban and rural areas of Beijing on their survival rate. Methods The elderly people with dementia aged 60 years and over lived in Beijing was investigated since 1997 by two step method and the mortality of the same population was followed up in 2000. Results A total of 2 788 patients were collected in 1997, and 2 721 of them were visited in 2000. Sixty seven(2 4%) of them were lost for follow up due to making a move and other reasons. Among the followed 2 721 cases , 2 307 were still alive (82 7%) and 414 died (14 9%), with the annual fatality rate being 3 79%(standardized). For all 205 cases diagnosed as dementia in 1997, the accumulated fatality rate was 42 46%(standardized), being 5 folds of the fatality for the non dementia. No significant difference was found in the fatality rate between male and female dementia. The fatality of dementia in rural area and over 75 years of age increased. Age and living conditions influenced significantly the fatality, and the fatality rate increased in patients with dementia and dysfunction of body moving. Conclusions Dementia is a disease impacting seriously the survival of elderly people.

Objective To investigate the treatment of perinail refracture after surgery of proximal femoral fracture.Methods From January 2010 to January 2015,we treated perinail fractures in 31 patients who had undergone surgery for proximal femoral fracture.They were 11 men and 20 women,with an average age of 75.6 years (range,from 24 to 87 years).On average,their refracture occurred 9.4 months after primary fixation (range,from 3 to 60 months).With reference to the Vancouver classification of peri-prosthestic refractures in the proximal femur and the position and bone quality of perinail refractures,we tried to classify the perinail fractures and chose different treatment protocols accordingly.In our cohort,6 were type A,5 type B,15 type C,and 5 type D.Type A cases were treated conservatively,and types B and C cases with locking compression plate or less invasive stabilization system.In one case of type D,dynamic hip screws were implanted to fixate the femoral neck fracture after removal of the original intramedullary nail,and hip replacement was conducted in the other 4 after removal of the original intramedullary nail.Results The operation time averaged 2.1 hours (range,from 1.6 to 3.0 hours) and intraoperative bleeding 600 mL (range,from 150 to 800 mL) in this cohort.Of them,27 were followed up for an average of 15 months (range,from 12 to 24 months),giving a follow-up rate of 87.1％ (27/31).Six type A fractures obtained bone union after protected weight-bearing walking for 12 weeks.All the 16 fractures of types B and C healed after an average period of 4.2 months (range,from 3 to 6 months).Of the 5 type D fractures,one obtained bone union 12 weeks after change into dynamic hip screwing and 4 had fine functional recovery after hip replacement.No infection,nonunion,or implants failure occurred.Conclusions We have set an exploratory classification system for the perinail refractures at the proximal femur with reference to the Vancouver classification of peri-prosthestic refractures.Our classification can provide effective guidance for the treatment of perinail refracture after surgery of proximal femoral fracture.

Objective To investigate the effects of breviscapine on the renal structure, function and PKC-?mRNA and its protein expression in brain-dead BA-Ma mini pigs. Methods Fifteen BA-Ma mini pigs were randomly divided into 3 groups: brain-dead group (group A), breviscapine pretreatment group (group B), and control group (group C), 5 pigs in each group. The brain-dead models were established by increasing intracranial pressure in a modified, slow and intermittent way. At 3, 6, 12, 18 and 24 h after the initial brain death, serum BUN, Cr, TNF-?, IL-1?, and IL-6 were determined. At 3, 6, 12, and 24 h, the changes of renal tissues were observed by HE staining, and the expression of PKC-?mRNA and protein was detected by RT-PCR and immnohistochemistry respectively. The ultrastructural changes of hepatic cells were observed under electron microscopy. Results (1) At 3rd h after the initial brain death, IL-1?, IL-6, and TNF-?in group A and group B began to increase. Serum BUN and Cr in group A and group B began to increase at 12 th after brain death and were higher at each time point (P

Objective To study the mechanism of acute portal vein thrombosis (APVT) after pericardial devascularization with splenectomy for the treatment of portal hypertension. MethodsThe expression of intercelluar adhesion molecule-1(ICAM-1) in spleen veins of 34 patients with portal hypertension and control vessels was studied by immunohistochemistry. Samples from spleen veins were examined by HE staining. Results The ICAM-1 level was higher in the spleen vessels in portal hypertensive (PH) patients than in controls (P

Objective To find out about the current health situation of the elderly in the Beijing area and their health care needs so as to provide basis for the formulation of health care policies for the elderly by the government and relevant departments and for the development of health care programs for the elderly in accordance with their needs. Methods A sample survey, covering such topics as the health situation, medical treatment, nursing, rehabilitation and health care needs of the elderly and community health service, was made of 2 487 elderly people aged 60 and above in different parts of Beijing, including the city proper, the part linking city and country, and the suburbs. An analysis was then made of the difference in the health situation and health care needs of the elderly between various parts and populations. Results Chronic diseases constituted the major health problem for the elderly, with hypertension, coronary heart disease, osteoarthrosis, and cerebrovascular disease ranking in the first four places and the incidence of diabetes increasing rapidly. About 10 percent of the elderly, who suffered from somatic dysfunction, had reduced daily life skills and needed assistance from others. An increased number of elderly people also meant a greater demand for medical and nursing services. Community health service, the advantages of which bacame increasingly manifest, was thus popular with the elderly. Financial difficulty was the chief factor affecting the elderly in their seeking medical service. Conclusion The elderly is a weak population in health. With the aging of the general population, the health care needs of the elderly are on the rise. As health is the major factor affecting the life quality of the elderly, enhanced efforts in the prevention and treatment of chronic diseases ought to be taken as the central task in the health care of the elderly. They are also the key to improving the life quality of the elderly.

OBJECTIVE:To strengthen the supervision of drug stocktaking,and to improve drug management. METHODS:The data of drug stocktaking were extracted from our hospital from 2011 to 2014,and was analyzed in respects of accounts coinci-dence rate,drug profit and loss account rate,the entry and exit account between departments and original record,etc. A series of supervision strategies were established,and the data of drug stocktaking was analyzed during Jan.-Jun. in 2015 statistically to evalu-ated supervision effects. RESULTS:The supervision of drug stocktaking was strengthened through limiting the right of drug profit and loss on stocktaking,strengthening original stocktaking record management,establishing Key Drug List,setting up drug stock-taking supervision institutions,etc. During Jan.-Jun. in 2015,there was obvious improvement in the drug supervision skills,in terms of account coincidence rate,profit and loss account,material safety,cash flow rate,staff responsibility and stocktaking dura-tion,etc. More specially,the accounts coincidence rate had rose from about 82.8% to more than 95%;both the key drug accounts coincidence rate and the entry and exit account between departments coincidence rate had reached to 100%;the profit and loss ac-count rate had reduced from about 7.6% to less than 0.3%;the stocktaking time had reduced from 10 h to 3 h. CONCLUSIONS:Strengthening drug stocktaking supervision can not only improve the stocktaking efficiency and quality markedly,but also contrib-utes to the development of other pharmacy work in hospital.
