Objective To investigate disease constitution of elderly inpatient in the Xuanwu Hospital, Capital Medical University in Beijing in 2011, so as to provide baseline data for further study. Methods Elderly (patients no less than 60 years old) inpatients’ records in the Xuanwu Hospital, Capital Medical University in 2011 were collected. Based on all the diagnosis on hospital discharge records, the diseases were standardized and classified according to the International Classification of Disease, 10th Edition (ICD-10). Data (including general information of the inpatients, all discharge diagnosis, and the distribution of disease type, age and sex) were analyzed through descriptive analysis using Microsoft Excel 2007 software. SPSS 17.0 software was performed for hypothesis test. Results a) The total numbers of elderly inpatients were 13 807 in 2011, accounting for 39.79% of all the inpatients. Males were more than females (male: female=1.26 to 1). The average kind of disease each patient was diagnosed with was 4.41, ranging from 1 to 11. b) The disease spectrum of patients with one disease was nervous system diseases, neoplasms, and digestive system diseases. The primary and secondary diseases of patients with two diseases were mostly circulatory system diseases. c) All the diagnosis included 18 categories, the top 7 were circulatory system diseases, endocrine, nutritional and metabolic diseases, digestive system diseases, respiratory system diseases, and nervous system diseases, accounting for 83.4% of all the diagnosis. The primary diagnosis included 18 categories, the top 5 were circulatory system diseases, neoplasms, digestive system diseases, respiratory system diseases, and nervous system diseases, accounting for 68.6% of all the elderly inpatients. d) In the circulatory system diseases, the top 5 diseases were cerebral infarction, occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction, angina pectoris, acute myocardial infarction, atherosclerosis, chronic ischaemic heart disease, accounting for 69.8% of all the circulatory system diseases patients. Diseases in different age and gender group were cerebral infarction, angina, acute myocardial infarction, and chronic ischemic heart disease (Plt;0.05). Conclusion The disease constitution of the Xuanwu Hospital, Capital Medical University is complex, and the primary diagnosis is mainly circulatory system diseases. It can be concluded that in the following studies attention should be paid to drug utilization of circulatory system diseases, so as to provide evidence for making the China specific potentially inappropriate medicine list and disease prevention for the elderly.
Objective To observe the expression of matrix metalloproteinase-9 (MMP-9), its tissue inhibitor of matrix metalloproteinase (TIMP-1), inducible nitric oxide synthase (iNOS) and contents of nitric oxide (NO) in the ocular tissues of Sprague-Dawley (SD) rats with endotoxin induced uveitis（EIU）. Methods Ninety SD rats were randomly divided into experimental (81 rats) and control group (9 rats). The model of EIU was induced in rats in experimental group by injecting with lipoplysaccharide (LPS) 200 μl into the hind feet pads, while the rats in the control group were not injected. Nine rats were executed 0, 6, 12, 18, 24, 48, 72, 96 hours and 7 days, respectively, after injecting with LPS; the NO content and concentration of protein in the aqueous humor in blood plasma, aqueous humor, and uveal tissues were detected. The expressions of MMP-9, TIMP-1 and iNOS in the ocular tissues were detected by immunohistochemistry, and the average absorbance (A) value was evaluated by computer medical image analysis system. Results iNOS, MMP-9 and TIMP-1 expressed in the epithelial cells of iris and ciliary body and exudated inflammatory cells of rats. The concentration of protein in the aqueous humor, the contents of NO in blood plasma, aqueous humor, and uveal tissues, and A value of MMP-9 had obvious relativity with the inflammatory extent, while no positive correlation was found between the inflammatory extent and the A value of iNOS and TIMP-1. Expression of iNOS was found 6 hours after injection, reached the peak after 12 hours, and then dropped gradually. The expression of TIMP-1 could be seen 24 hours after injection, and reached its peak after 72 hours. Conclusion The content of NO and expressions of iNOS, MMP-9 and TIMP-1 changes from the beginning and during the development of EIU, which suggests that NO, iNOS, MMP-9 and TIMP-1 are involved in the pathologic process of EIU.
