ABSTRACT
<p><b>BACKGROUND</b>Based on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.</p><p><b>METHODS</b>The Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.</p><p><b>RESULTS</b>A total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).</p><p><b>CONCLUSION</b>We first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.</p>

ObjectiveTo explore the correlation between the prevalence of benign prostatic hyperplasia(BPH) and metabolic syndrome (MS)in the army elderly.Methods Totally 1 230 veterans (aged 70 years and over) from 26 military sanatorium in Shijiazhuang city were studied.The prevalence of BPH and MS was calculated.ResultsThe prevalence of BPH among the elderly was 77.0％.There was a trend of increase in the prevalence of BPH with increasing age (x2 = 50.4,P＜0.01).The prevalence of MS among the male elderly was 19.6％.MS was a risk factor for BPH(x2 =24.2,P＜0.0001).ConclusionsMS may be one of risk factors for the prevalence of BPH.
ABSTRACT
OBJECTIVE:To prepare Potassium dehydroandrographolide succinate(PDS)hollow suppository and establish a method for its quality control.METHODS:The PDS hollow suppository was prepared with semisynthesis fatty acid glyceride as ground substances and PEG300 or 1,2 propylene glycol as disperse medium.The content of PDS was determined by ultraviolet spectrophotometry at a detection wavelength of 251nm.RESULTS:The linear concentration range of PDS was 6.0～50.0?g?mL-1(r=0.999 9,n=5).The two kinds of PDS hollow suppository were all up to the quality standard.CONCLUSION:This method is reasonable in design and feasible in technology.
ABSTRACT
BACKGROUND: Mild cognitive impairment (MCI) in elderly people is becoming increasingly a new hot spot for the clinical study of Alzheimer disease at present, and it is still unknown how many cases of MCI will convert into Alzheimer disease. OBJECTIVE: To analyze the incidence rate of mild cognitive impairment and the conversion rates into dementia and Alzheimer disease among elderly people.DESIGN: A prospective cohort study based on diagnosis. SETTING: Second Department of Cadre's Ward, Bethune International Peace Hospital of Chinese PLA.PARTICIPANTS: The subjects were 216 MCI patients and 2 302 subjects with normal cognition selected in the baseline investigation to the retired cadres aged 60 years and above, in 26 military cadres' sanatoriums of Shijiazhuang city between August and September 2001.METHODS: The MCI diagnosis was according to the MCI diagnostic standard in Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-Ⅳ), and the diagnosis of dementia was according to the standard in DSM-Ⅳ revised by American Psychiatric Association. Alzheimer disease was diagnosed according to the standards of National Institute of Neurological and Communicative Disorders and Stroke/the Alzheimer Disease and Related Disorders Association (NINCDS-ADRDA). All the 216 MCIpatients and 2 302 subjects with normal cognition were enrolled in the 3-year cohort study. MAIN OUTCOME MEASURES: The incidences of MCI among subjects with normal cognition; the annual conversion rates into Alzheimer disease in MCI patients and subjects with normal cognition; the relative risks (RR) and 95% confidence interval (95% CI) of MCI and normal cognition developing into Alzheimer disease. RESULTS: The MCI group and normal cognition group were followed up once every year for 3 years. Of the 216 MCI patients, 7 died, and 209 were followed up actually, and the follow-up rate was 96.8%. Of the 2 302 subjects with normal cognition, 36 died, and 2 266 were followed up actually,and the follow-up rate was 98.4%. ① In the elderly subjects with normal cognition, the annual incidence of MCI was 4.8%, and those of dementia and Alzheimer disease were 1.3% and 0.8 respectively. ② The annual in cidence rates of dementia and Alzheimer disease in MCI patients were 8.1% and 5.6% respectively, which were insignificantly different between males and females (P ＞ 0.05). ③ The incidence rates of dementia and Alzheimer disease showed a descending trend with the elevation of educational level in both the MCI patients (trend x2 =5.57, P=0.02; trend x2 =4.92, P=0.03) and the subjects with normal cognition (trend x2 =23.1, P＜ 0.001; trend x2 =18.0, P ＜ 0.001). ④ The annual incidence rates of dementia and Alzheimer disease showed an ascending trend with aging in both the MCI patients (trend x2 =14.6, P ＜ 0.01; trend x2 =13.9, P ＜ 0.01) and the subjects with normal cognition (trend x2 =32.3, P ＜ 0.01; trend x2=23.8, P ＜ 0.01). ⑤ The relative risks of the conversion into dementia and Alz heimer disease in MCI patients were 6.4 and 7.4 times as many as those in the subjects with normal cognition.CONCLUSION: The risks of conversion into dementia and Alzheimer disease in elderly MCI patients are far higher than those in elderly people with normal cognition. It should be reinforced to monitor elderly MCI patients, who are the of high risk group of dementia.
