Helicobacter pylori(Hp) is an important pathogenic factor in chronic gastritis,peptic ulcer and gastric cancer.With the extensive use of broad-spectrum atibiotics in recent years,the antibiotic resistence of Hp was increasing,together with many side effets and low patient compliance,so the study of new anti-Hp drugs became a research hotspot.Domestic and foreign scholars had extracted active anti-Hp ingredients from the traditional Chinese drug curcuma,they hope to open a new way for the treatment of Hp infection.This paper was to make a brief overview on the study progress of effect of curcuma on anti-Hp.

Objective　To observe the characteristics and statistics in the bi-variable distribution of thyroid volume (ml) and urine iodine level (μg/L) of children aged 8,9,10 years in China,1999.Methods　Classing analysis.Results　①Data of 12982 cases collected from all country are analyzed with cluster method and three clusters are delimitated as follows;②in first cluster,according to the calculation of median,the volume of thyroid gland is small (2.2ml) and the level of urinary iodine is high (369.1μg/L);③in second cluster,the volume of thyroid gland is middle size (3.4ml) but the level of urinary iodine is significantly lower (88.0μg/L) than that in the first cluster;④in third cluster,the thyroid volume is highest (4.1ml) and the level of urine iodine is high (363.4μg/L),too;⑤the meanings of the classifying results are discussed in detail.Conclusions　The results of the cluster analysis reported here and the typical analyses of the previous papers suggested that no low iodine problems be found out but the correlation between the increasing of thyroid volume and the higher level of urine iodine be observed by us in the studies.

Objective　To discover and discuss the charac ter and statistics of frequency distribution of thyroid volume (TV) in Chinese c hildren aged 8,9,10 years for setting up an effective strategy to control the endemic goiter in China.Methods　The TV is measured by B-ultrasonography.The da ta of a great sample collected from all country are treated with computer centra lly in Chinese Research Center for Endemic Disease Control.Results　①In 1999,the statistics of TV(ml) of children aged 8,9,10 years in China are 3.6 of mean,3.4 of median,3.0 of mode,5.9 of 95% point and 7.9 of 99% point.②The values of 95% point in frequency distribution of TV in 8,9,10 years of boy in order are 4.8,5.6 and 6.3,and in girl they are 5. 2,5.8 and 6.5.③The disparity in medians of TV of children is very significant between the studied provinces;the lowest is Shanghai,the mediums are Anhui and Sh anxi,and the higher ones are Chongqing,Guizhou and Xinjiang,and the medians of the TV in these three categories are 1.2,3.7 and 4.0 in order.④Differential effe cts of palpation method in detection of TV are discussed carefully in this paper .Conclusions　The cause inducing to the significant diffe rences of children TV in several regions in China is not known yet,but it is not the nutritional problem of iodine certainly.

Sucking mice, 2～3 day after birth, were intraperiton eally inoculated with 0.05mL F1M10 of Chen Strain Hantaan virus. At diff erent t ime point after inoculation, the brains were taken, routinely fixed and embedded in paraffin for preparing 5 μm serial sections. Traditional and confocal immun ochemical detection of viral antigens and heat shock protein 70 were performed t o exp lore the cerebral stress response after viral infection. The results showed that HSP70 immunoreactivities could be stably detected in the viral antigen positive neurons, but not in the viral antigen negative or uninfected control tissues. B y confocal microscopic examination, the HSP70 and viral antigens were colocolize d in the neuronal cytoplasm. Our result, comparable to our previous findings in human tissues and culture cells, indicated that Hantavirus infection can induce the expression of HSP70 in the infected cells, and HSP70 expression might be n ecessary but not sufficient to keep the cell survival.

Objective To study whether the measure of consumption of iodized salt to prevent iodine deficiency disorders could lead to residents excessive iodine intake in the coastal areas in China.Methods A large population-based cross-sectional study was carried out in four typical costal provinces along the coastline from north to south,including Liaoning,Shanghai,Zhejiang and Fujian.In addition to survey all of its area of Shanghai,the other three provinces' investigation was carried out at urban and rural levels,respectively,including 5 costal cities,5 costal villages and 3 inland rural areas(as a control point) in each province.In each investigated spot,the local water iodine,residents qualified iodized salt consumption rate,per capita daily intake of salt and urinary iodine levels in different populations were investigated.Results A total of 7552 copies of drinking water samples,7996 salt samples and 9873 urine samples of different populations(adults,lactating women,pregnant women and children) were collected from the 4 provinces.Except the coastal cities and counties of Zhejiang province,the qualified iodized salt consumption rates at household were all greater than 90％ in the investigated spots.The median urinary iodine(MUI) of adults and children investigated in the costal areas were in the range of 100 - 299μg/L.The MUIs of lactating women of all investigated areas were all greater than 100 μg/L.The MUI of pregnant women was at an insufficient iodine level which was lower than 150 μg/L in Shanghai,the costal cities of Zhejiang and the coastal counties of Fujian.Conclusions The overall level of iodine nutrition of coastal residents is appropriate; and it is insufficient among pregnant women in some coastal areas; coastal areas should adhere to the salt iodization measures to control iodine deficiency disorders.

Objective To investigate the iodine content of food in six provinces of China,to add the results of this survey to the food iodine content database,and to provide a scientific basis for iodine supplementation in different parts of China.Methods A total of 8 categories and 39 species common food produced locally in the six provinces of Fujian,Chongqing,Shandong,Anhui,Gansu and Jilin were collected.Samples of cereals,beans and other dry samples were crushed into powder; samples of fresh fruits and vegetables were washed and dried to constant weight,and crushed into powder; poultry,meat and fish samples were washed and then their edible parts were crushed into meat paste,bake dried to constant weight,and crushed into powder.Iodine content in the above-mentioned food was determined by catalytic spectrophotometry,and the wavelength was 405 nm.Data processing and statistical analysis were carried out by using SPSS 13.0 statistical software.The results of total iodine content of the various types of food were expressed as median(P50) and interquartile range(P25 and P75).Results The iodine content of the cereal in Fujian,Chongqing,Shandong,Anhui,Gansu and Jilin were 11.9,12.0,48.0,95.1,13.0and 3.1 μg/kg,respectively; of the potato were 53.9,26.3,74.9,43.7,76.8 and 38.5 μg/kg,respectively; of the meat and the eggs were 56.0,30.4,78.6,124.6,47.7 and 34.8 μg/kg,respectively; of the aquatic products were 319.3,144.7,186.6,241.3,155.4 and 213.3 μg/kg,respectively; of the vegetables were 166.6,145.1,131.7,218.0,205.4 and 98.1 μg/kg,respectively; of the fruits were 105.5,17.8,80.9,1.7,76.7 and 10.3 μg/kg,respectively; of the kelp and laver were 36.0 × 103,1292.0 × 103,2810.0 × 103,48.0 × 103,75.0 × 103 and 120.0 × 103 μg/kg,respectively; of the Chinese pickled vegetables were 640.4,4163.5,3073.7,2635.3,1540.9 and 492.0 μg/kg,respectively.ConclusionsThe iodine content of different types of food,and same kind of food from different provinces are different.The results are a complement to the 2004 Chinese food composition database.

Objective To explore the application of high-frequency oscillatory ventilation(HFOV)postoperatively after open heart surgery in children with congenital heart disease.Methods From Jun.2007 to Jun.2008,a total of 1 957 cases were operated in pediatric center of Fuwai cardiovascular hospital.Thirteen cases of 1 957 were given HFOV.Among these 13 patients,8 were male and 5 were female;Age was(13.4?15.4)months.The range of weight was 4.2-12.5 kg.Four cases were tetralogy of Fallot,3 cases were transposition of the great arteries(1 case was corrective transposition of the great arteries),2 cases were total anomalous pulmonary venous connection,2 cases were total endocardial cushion defects,2 cases were pulmonary artery atresia,all patients were under cardiopulmonary bypass repaired operation except 1 patient with PAA under Blalock-Taussig procedure.All patients were mechanical ventilated after surgery.Results The duration of switching general mechanical ventilation to HFOV was(15.70?20.33)days and patients continued to be on HFOV about(10.0?7.5)days.In short term,the lung function of ventilation and gas exchange were be improved by HFOV,but the long-term result was not sa-tisfactory due to a high mortality.There were 5 survived(38.4%)in this group.Six cases of the patients succumbed to consolidation of lung.The commonest complication was pneumothorax(7 cases).Conclusions Short term of HFOV in children with congenital heart disease was satisfactory postoperatively.But there was a high mortality.HFOV can be regarded as a transition method for unsatisfactory long-term.
