ABSTRACT
Objective To investigate the present status of Kaschin-Beck disease(KBD) in Qingzhou at present, and provide a scientific basis for decision-making in controlling the disease. Methods According to The National Technical Scheme for Endemic Disease Control in 2007, children aged 7 to 12 were chosen to receive clinical and X-ray examination in 3 villages of 2 towns in Qingzhou. Local adults aged 16 years and older were clinically diagnosed in 10 villages of 4 towns and divided into different groups according to the clinical degrees and their ages. The Diagnostic Criteria of Kashin Beck Disease(GB 16003-1995) was carded out by clinical and X-ray diagnosis. Results Two hundred and sixty school children aged 7 to 12 were clinically diagnosed, and the patients of I degree upwards of KBD were not detected. One hundred and ninety-eight school children aged 7 to 12 were examined by X-ray, and the detectable rate was 0(0/198). In 7099 adults aged 16 years old upwards clinically tested, 502 patients of degree I and higher of KBD were detected and the detectable rate was 7.07%(502/7099). The patients distributed mainly in the population aged 36 years old and older, accounting for 99.00% (497/502). Conclusions Although KBD in children have been controlled in Qingzhou, it is still serious in adults. So the monitoring of KBD should be carried on and prevention and control for KBD in adults should be strengthened.
ABSTRACT
Objective To analyze the epidemiologieal features and treatment of brain injury in Chinese Wenchuan earthquake so as to provide the experiences for improving treatment level. Methods A total of 685 patients with earthquake-induced brain injury in the City of Deyang were collected to ana-lyze age, injury type, injury localization and treatment characteristics. Results Of large number of earthquake victims, the number of the patients with brain injury ranked the second place, mainly minor and moderate brain injuries involving scalp laceration for the most and skull fracture and extradural hema-toma for the next. As for the age distribution of the patients, young and middie-aged patients accounted for the most, for they were at school or at work when the earthquake happened. Obvious position distribu-tion features were found in depressed fracture of skull and extredural hematoma but not in the scalp lacera-tion. Depressed fracture of skull occurred mostly at forehead and occiput while extradural hematoma could be most seen at froutotemple. Most brain injuries were combined with other injuries. Mainly extremity and pelvic fractures. Conclusions Self-protection sense and measures during earthquake are very important for decreasing incidence and severity of brain injuries. The management of rospimtory tract in prehospital care should be strengthened to avoid asphyxia and hence raise the success rate of treatment.
ABSTRACT
Objective To investigate Alzheimer's disease(AD) and vascular dementia(VD) status and distribution in middle-aged and elderly population in Xinjiang Uigur and Han nationalities to provide the data for the further study of the causes and prevention of AD. Methods From July 2004 to June 2007, according to the DSM-Ⅳ-R diagnostic criteria for dementia and N1NCDS-ADRDA criteria, multi-stage stratified random cluster samphng approaches were adopted in 6 areas in southern, eastern, northern Xinjiang Urumqi City Community to investigate middle-aged and elderly Uigur and Han people older than 50-year-old suffering from AD. Results A total of 8284 were surveyed, Xinjiang AD crude prevalence rate was 3.66%, Uigur and Han AD accounting for 3.24% and 4. 19% respectively. According to the age composition of 2000 census of Xinjiang, AD adjusted standardized incidence was 3.50%, 2. 68% and 4. 31% for Uigur and Han respectively; Xinjiang VD crude prevalence rate was 1.05%, with Uigur and Han VD crude prevalence rates being 1.11% and 0. 97% ,respectively. Xinjiang VD standard rate was 0.98%, Uigur and Han accounting for 1.00% and 0. 96% respectively. Prevalence rate of men and women had significant differences among age groups, and increased along with age (Uigurs χ2= 186. 286, P = 0. 000 ; Hans χ2=77. 131 ,P =0. 009). The Uigur, Han AD prevalence rates obviously reduced with the increase of educationallevel(Uigurs χ2=12.291,P=0.002;Hans χ2=61.539,P=0.000). Conclusions AD standardized rate in the elderly in Xinjiang Uigur and Hart ethnic groups is significantly higher than the national average. AD prevalence rate is comparably higher than that of VD. There are significant differences among the nationality, gender, age and culture.
