Objective To investigate the related risk factors for stroke among residents aged over 26 years old in communities in Chongqing,to set up a quantitative criteria for determining risk for stroke,and to evaluate and predict the risk of the stroke for individuals.Methods 1 034 cases with 1:2 matched controls were chosen from five communities in Chongqing,which were interviewed with a uniform questionnaire.The risk factors of stroke were analyzed with Logistic regression,collected the odds ratios of risk factors for stroke,and different levels of risk exposure factors be converted into a risk scores by using statistical models.The related risk scores were added to obtain a combined risk score to predict the individual's risk of stoke in the future.Results An individual health risk appraisal model of stroke applicable to individuals of different sex,age,health behavior,disease and family history was established.For men,11 risk factors,including hypertension(5.728),coronary heart disease(5.404),family history of stroke(4.599),and so on,were entered the main effect model;for women,hypertension(5.270),family history of stroke(4.866),hyperlipidemia(4.346),and other eight risk factors entered the main effect model.Conclusion Personal diseases,including hypertension,CHD and hyperlipidemia,etc.,are very important risk factors for stoke.The stroke prevalence can be effectively reduced by changing the unhealthy lifestyle and curing the related individual diseases.The evaluation model of the risk score for stroke based on the main risk factors could be useful in the future health education and community health service on stroke prevention.

BACKGROUND: The structural and functional changes in resistance arteriole of external diameter ＜300 μm is one of the pathological foundations for ischemic cerebrovascular diseases, however there are few quantitative study on the arterioles of various external diameter at different brain area.OBJECTIVE: To probe the difference of arteriolar sclerosis of various external diameter at different brain area after cerebral infarction.DESIGN: Sample investigation.SETTING: Department of Nerve Internal Medicine, General Hospital of Beijing Military Area Command of Chinese PLA.SUBJECTS: Specimen was taken from donated autopsy case in General Hospital of Beijing Military Area Command of Chinese PLA from January 1980 to September 2000. According to the clinical manifestation, brain CT inspection and pathological diagnosis of autopsy, 38 cases were defined as arteriosclerosis cerebral infarction and taken as experimental group, other 15 cases with non-cardiac cerebrovascular disease were taken as controls.METHODS: specimen was obtained in 1-3 days after death from frontal and parietal cerebral cortex and basal gonglion white matters (3 pieces /case) and cut into slices. Five fields of vision were selected from each slice for microscopic observation. Arteriole was divided into ＜ 50 μm group,50-100 μm group and ＞100 μm group according to the arteriole external diameter. (External diameter- internal diameter)/internal diameter was used to assess vascular sclerosis.MAIN OUTCOME MEASURES: [1] Difference of arteriole sclerosis between corresponding external diameter cerebral infarction group and control group. [2] Arteriole sclerosis in various brain region in cerebral infarction group.RESULTS: Totally 38 experimental cases died from arteriosclerosis cerebral infarction and 15 controls died from non-cardiac cerebrovascular disease were enrolled and all data was entered the result analysis. [1] The arteriolar sclerosis index was obviously higher in ＜ 50 μm external diameter cerebral infarction group than in 50-100 μm group and ＞100 μm group[(138.55±76.67)% vs (116.82±58.80)%, (78.07±32.06)%, P ＜ 0.01], while it was approximately the same in the 100 μm external diameter group and control group [(78.07±32.06)% vs (46.38±13.41)%, P=0.174 ]. [2] In ＜ 50 μm external diameter cerebral infarction group, the arteriolar sclerosis index in white matters was significantly higher than that in gray matter [(152.86±87.83)%,(127.97±64.76)%, P ＜ 0.05 ].CONCLUSION: Arteriolar sclerosis degree is correlated with its external diameter and position in patients with cerebral infarction after arteriosclerosis, arteriole of small external diameter or in the white matter has higher arteriolesclerosis liability.

Objective To investigate the effects of dexmedetomidine on hemodynamics and tra-cheal intubation facility in general anesthetized patients.Methods Forty gynecological patients of se-lective operation under general anesthesia were randomly arranged into 2 groups:group D and group C.With high flow mask oxygen inhalation(5 L/min),dexmedetomidine was intravenously pumped in-to the patients in group D at 0.6μg/kg in 10 minutes while in group C saline were given instead.Both groups were then proceeded with rapid sequence induction (RSI)immediately.The values of MAP, HR,PaO2 and PaCO2 were recorded every minute from pumping start till 15 minutes,the bucking, intubation time and glottis exposure were evaluated as well.Results No significant differences were found in intubation time or glottis exposure between these two groups.After tracheal intubation group D showed higher MAP value than group C at 14,15 minutes,and a lower HR value (P <0.05).Even no significant differences were found in values of SpO2 and PaO2 ,the group D showed less bucking than the group C (P<0.05).Conclusion Dexmedetomidine administration at 0.6μg/kg in RSI can diminish the variation in hemodynamics and facilitate the tracheal intubation by less buc-king,but no affect the oxygen reserve.

OBJECTIVE:To detect the contents of chlorogenic acid and rutoside in Saussurea involucrate,and to optimize the decoction and extraction technology of S. involucrate from different producing areas. METHODS:The contents of chlorogenic acid and rutoside in 10 batches of S. involucrate from different producing areas were determined by HPLC. L9(34)orthogonal experiment was used to optimize the water amount,decoction times and decoction time using comprehensive score of extraction transport rate of chlorogenic acid and rutoside as index. The verification test was also conducted. RESULTS:The contents of chlorogenic acid and rutoside in 10 batches of S. involucrate were 0.380%-0.546% and 0.334%-0.617%;the optimal decoction technology was as follows as the amout of crude material of S. involucrate 100 g,soaking for 20 min,decocting for 3 times,12,10 and 10 fold of water,decocting 45,30 and 30 min,respectively. The extraction transfer rates of chlorogenic acid and rutoside were 96.2%(RSD=2.66%,n=3)and 89.3%(RSD=3.31%,n=3)in verification test. CONCLUSIONS:For S. involucrate from different producing areas,the contents of effective components are different;optimized decoction and extraction technology is stable and feasible.

The 20th National Congress report proposed the most important and core strategic path of national governance:Chinese modernization.Under the guidance of the top-level design,the healthcare security system needs to find a new paradigm of healthcare security governance under the Chinese modernization that is both in line with Chinese characteristics and the basic laws and characteristics of the world's sanitary resources.Combined with the 20th National Congress report,the medical reform tasks of"promoting the development and governance of medical services,medical insurance and pharmaceutical synergy"and"promoting the inheritance of Traditional Chinese Medicine"are required to learn from the international"disproportionate share"health resources compensation system.From the perspective of necessity and adaptability,it explore the Traditional Chinese Medicine(TCM)disproportionate share mechanism of medical insurance,in order to maximize the realization of the strategic purchasing goal of health insurance and to provide a systematic,standardized and sustainable modernized Chinese health insurance model for the continuous support of TCM medicine special diagnosis and treatment with medical insurance resources.
