OBJECTIVE:To study the common characteristic component peaks in water decoction of crude curcumae radix and the vinegar roasted products from 4 different sources,compare the contents of its water decoction,and provide reference for resolv-ing the multi-source of curcumae radix piece in clinical application,complementing and improving the quality standard of curcumae radix. METHODS:HPLC was used to determine the characteristic spectrums of crude curcumae radix and the vinegar roasted prod-ucts from different sources (Curcuma wenyujin,Curcuma kwangsiensis,Curcuma longa,Curcuma phaeocaulis),and component analysis was conducted by using fingerprint software and mirror comparison. And the changes of water decoction content before and after vinegar roasted were compared. RESULTS:Both crude curcumae radix and the vinegar roasted products from 4 different sourc-es had 7 common characteristic component peaks. Vinegar roasted had effect on peaks in different degree,some peaks areas were in-creased,some peaks areas were reduced,some peaks were generated,and some peaks were disappeared. However,the common components of curcumae radix from different sources showed no qualitative changes after vinegar roasted,except the increase or de-crease in peak areas. Areas of 5 common component peaks were increased in the 7 common components of C. wenyujin,C. kwang-siensis and C. longa after vinegar roasted,and only 3 in C. phaeocaulis after vinegar roasted. Contents of 4 water decoctions were increased after vinegar roasted. CONCLUSIONS:There are 7 common components in curcumae radix from 4 different sources. Vin-egar roasted has no qualitative effect on common components,while it can increase the chromatographic peak areas and contents of water decoction.

Objective To analyze the relationship between blood glucose,blood lipid and body mass index (BMI) in elderly patients with hypertension.Methods Form January 2016 to December 2017,376 hypertensive patients over 65 year old in Jinan city were enrolled in this study.The sex,age,BMI,fasting blood glucose and blood lipid were investigated and tested.The prevalence of coronary heart disease and diabetes mellitus in hypertensive patients were investigated,and the relationship between BMI and blood glucose,blood lipid and liver function index were explored.Results Of 376 hypertensive patients,the detection rate of diabetes mellitus was 21.01％ (79/376),221 cases were diagnosed with coronary heart disease,with the detection rate of 58.78％.With the rise of BMI,fasting blood glucose showed an upward trend.Person correlation analysis showed that there was a significant positive correlation between BMI and fasting blood glucose(r =0.167,P =0.003).The difference between TG and TC in different BMI groups was statistically significant(FTG =12.48,P ＜ 0.001;Frc =4.83,P ＜ 0.001).The content of alanine transaminase in the overweight group and obese group was significantly higher than that in the normal body weight group,the difference was statistically significant(F =5.24,P =0.005).Conclusion For elderly hypertensive patients,it is urgent to test blood glucose and coronary heart disease screening.For people over the age of 65,obesity is still an important risk factor for hyperlipidemia and hyperglycemia.Therefore,body weight control is needed in elderly patients with hypertensive.

Objective To explore the effect of health education on endemic fluorosis in Shandong Province,and provide evidence for further development of health education measures.Methods From 2011 to 2015,using prospective method,19 endemic fluorosis counties (cities,districts) were selected as project counties in Shandong Province each year,and 3 townships (towns) were selected in each project county.Health educational activities on prevention and treatment of endemic fluorosis were carried out in the classes of grade 4-6 in the central primary school;3 administrative villages were selected in each township (town) to carry out community health education activities.Before and after the health education activities,questionnaire surveys on the health education of endemic fluorosis prevention knowledge were conducted among 30 students of grade 5 in the central primary school and 15 housewives lived near the schools in each township (town).Results The results of health education evaluation showed that the'awareness rate of prevention and treatment of endemic fluorosis in school students and housewives were 95.64％ (27 770/29 037) and 92.09％ (14 341/15 573),respectively,which were significantly higher than those before the intervention [69.40％ (20 157/29 043) and 67.40％ (10 375/15 393)],and the differences were statistically significant (x2 =6 926.73,2 928.85,P ＜ 0.05).Among the primary school students and housewives,the knowledge awareness rates of prevention and treatment of endemic fluorosis were increased by 26.24％ and 24.69％,respectively.Conclusion After implementation of endemic fluorosis health education intervention,the awareness rate of prevention and treatment knowledge in local fluorosis areas in Shandong Province is significantly increased,which means we can further expand the scope of health education.

Objective To investigate the endemic fluorosis of drinking water type in 3 counties in the northwest of Shandong Province,and to provide scientific basis for prevention and control of endemic fluorosis.Methods Seven villages in 3 counties of Ningjin,Xiajin and Wucheng were investigated to achieve the results including fluoride of drinking water,8-12 year-old children's dental fluorosis incidence rate,the fluoride of urine,prevalence of skeletal fluorosis by clinical and X-ray diagnosis in adults over 30-year old,and the bone mineral density.At the same time,set up a control point to detect the adult bone density in non-ward village of each investigated county,The water and urine fluoride were checked by selective electrode method,dental fluorosis was diagnosed by Dean method (WS/T 208-2011) and the diagnosis of adult fluorosis was performed in accordance with the diagnostic criteria of endemic fluorosis (WS 192-2008),and bone mineral density was measured by EXA-3000.Results The villages in Ningjin and Wucheng had finished defluoridation,where the water fluoride was at normal level.In the 7 villages,the total detection rate of 8-12 year-old children's dental fluorosis was 85.09％ (411/483),dental fluorosis index was 1.88;the dental fluorosis detection rate in Wucheng,Xiajin and Ningjin was 92.48％ (295/319),88.76％ (79/89) and 49.33％ (35/75),respectively,the difference was statistically significant (x2 =90.26,P ＜ 0.01).The average urine fluoride geometric mean of children (206) and adults (298) was 3.29 and 3.41 mg/L,respectively.The urine fluoride of Xiajin was the highest in the 3 counties,and the average urine fluoride geometric mean of the two groups was as high as 5.11 and 6.30 mg/L,respectively.The total detection rate of clinical and radiographic skeletal fluorosis in adults was 30.07％ (92/306) and 14.38％ (44/306),respectively.The osteoporosis detection rate of adults in endemic fluorosis area and non-endemic fluorosis area was 33.11％ (100/302) and 8.99％ (17/189),respectively.The difference was statistically significant (x2 =37.25,P ＜ 0.01);the average bone mineral density in endemic area and non-endemic area was 0.416 and 0.475 g/cm2,respectively,the difference was statistically significant (t =8.508,P ＜ 0.01).Conclusions The endemic fluorosis in the 3 counties in the northwest of Shandong Province is still existed.The defluoridation has not been completed in Xiajin County.Therefore,it is necessary to implement defluoridation measures of the drinking water as soon as possible and strengthen the water fluoride monitoring so as to prevent and control endemic fluorosis.

Objective To analyze the influencing factors of water iodine in Shandong Province.Methods The county-based study set Shandong Province as a research site.The water iodine data of county (city) from 2008 to 2010 were obtained from Shandong Institute for Prevention and Control of Endemic Disease.Water iodine content was used as a dependent variable,and soil type,hydrogeological type,topography and distance to the Yellow River were analyzed as independent variables.Normality test and general linear regression analysis of the dependent variables were performed using SAS 9.3 software;geographically weighted regression (GWR) analysis was performed using SAM V4.0 software;related electronic maps were drawn using ArcGIS 9.3 software.Results A total of 108 164 water iodine content data were collected.General linear regression analysis showed that the constructed regression model was statistically significant (F =16.29,P ＜ 0.01),and the soil type was included in the model with a determination coefficient (R2) =0.51.GWR analysis showed that R2 =0.63 and the adjustive determination coefficient (R2adj) =0.59.Considering the autocorrelation of the variable space,the model's goodness of fit was better than that of the traditional general linear regression model.GWR analysis showed that soil type and distance to the Yellow River were major factors related to water iodine in Shandong Province.There was a negative correlation between soil type and spatial variability of water iodine in most areas of Shandong Province,the correlation coefficients weakened gradually from west to east,indicating a geographic gradient variability.The correlation coefficients of distance to the Yellow River and spatial variability of water iodine were negative in some areas,while they were positive in other areas,indicating a clear geographical variability from southwest to northwest.Conclusion The soil type and the distance to Yellow River are important factors affecting the spatial distribution of water iodine in Shandong Province.
