In recent years,the potential impairments of organic pollutants in water on human health and the removal of organic pollutants in drinking water have become a worldwide concern.Some subjects from the impairments of the genotoxicity of organic pollutants to the prevention of water pollution,had been assessed widely by researchers and schoolars.The results showed that,the impairments of the organic pollutants in water on human health were preventable,and its preventive methods presented a good prospect for extensive use.

Objective To investigate the significance and possible mechanism of food intolerance in diarrhea-predominant irritable bowel syndrome (IBS-D).Methods Twenty-seven IBS-D patients matched the Rome Ⅲ criteria were selected as IBS-D group.Twenty-seven healthy individuals without gastrointestinal symptoms were assigned to control group.Food intolerance situation of two groups were analyzed with food intolerance status evaluation questionnaire,and detection of 14 food specific IgG antibody.The severity of IBS symptoms of IBS-D group were scored by IBS-symptom severity scale (SSS).Two pieces of mucosal tissues of both ileocecal junction and sigmoid colon were obtained under colonoscopy.The content of mucosal substance P (SP) was determined by immunohistochemistry.The quantity of mast cells were detected by Giemsa staining.Chi square test and Fisher exact probability method were performed for rate comparison between two groups.Measurement data were compared with t test and Mann-Whitney rank sum test.The correlation between IBS-SSS score and mast cells and the expression of SP positive cells were analyzed by Spearman rank correlation analysis.Results There was no statistically significant difference in positive rates of food specific IgG between two groups (x2 =3.085,P=0.389),however according to food intolerance status evaluation questionnaire,the incidence of food intolerance of IBS-D group was 44.4 ％ (12/27) which was higher than that of control group (14.8 ％,4/ 27),the difference was statistically (x2 =5.684,P=0.017).Food intolerance severity index of IBS-D group (median:0(0,60)) was higher than that of control group (median:0(0,0)),and the difference was statistically significant (U=239.50,P =0.007).In foods that may cause intolerance,the percentage of foods rich in fermentable oligosaccharides and monosaccharides,disaccharides and polyol (FODMAP) such as milk,noodles,soybeans was up to 71.4％ (30/42).The expression tates of SP positive cells in the mucosa of ileocecal junction and sigmoid colon of patients with IBS-D were higher than those of the control group (x2-20.735 and 22.071,both P＜0.01).The numbers of mast cell in the mucosa of ileocecal junction and sigmoid colonic of patients with IBS D (2.40 ± 1.04/high power field (HPF) and 2.35±1.11/HPF) were more than those of the control group (0.97 ± 0.70/HPF and 0.89 ± 0.72/HPF),and the difference was statistically significant (t=-5.850 and-5.629,both P＜0.01).The severity of bowel symptom of patients with IBS-D was moderately correlated with the number of mast cells in the mucosa of sigmoid colon (r=0.576,P=0.002),and was moderately correlated with the expression of SP positive cells (r=0.691,P＜0.01).Conclusions There may be relation ship among low-grade inflammation of intestinal mucosa,food intolerance and severity of intestinal symptoms in patients with IBS-D.

Objective]To research the impact of Danxi’s medical science on Kampo medicine system and summarize its development in Japan,for providing ideas for the research of Chinese medicine. [Method]Learning Zhu Danxi related books and Kampo medicine literature, analyse the impact of Danxi ’s medical science on each genre of Japan Kampo medicine,explain the role of Danxi ’s medical science in the formation and development in Japan Kampo medicine system,and ummarize its development path in Japan.[Result]The development of Danxi ’s medical science in Japan experienced ups and downs, combined with local realities,and derived more Japanese-oriented medical theories. [Conclusion]Danxi ’s medical science not only for the formation of Japanese Kampo medicine system plays an important role, but also has a profound impact on Japan's three Kampo medical genre.Its development track is worth thinking and summarizing.

Purpose:To explore the relationship between the occurence of acute respiratory failure after subototal esophagectomy and three-field lymphadenectomy and the choice of anesthesia and management.Methods:From March 2000 to Janunary 2001,thirty-seven patients scheduled for subtotal esophagectomy and three-field lymphadenectomy with e- sophageal cancer,adopting the combination of epidural,cervical nerve block,and general anesthesia were studied.Re- sults:Seven cases out of thirty-seven had acute respiratory failure,accounting for 19% in whole group.They had complete recovery after antifectious therapy and respiratory support.Conclusions:To combine the epidural,cervical nerve block and general anesthesia can reduce intravenous anesthetics use and shorten the extubation time,decrease the incidence of postop- erative respiratory failure.

Objective To evaluate the values of amplitude-integrated electroencephalogram(aEEG) on the diagnosis of hypoxic ischemic encephalopathy(HIE),and the changes of aEEG in HIE with hypother-mia treatment.And to assess the therapeutic effect of hypothermia.Methods The changes of aEEG were continuously monitored before and after hypothermia treatment,and the proportions of various waveforms ap-pearing in aEEG were analyzed.Results A total of 90 cases were enrolled in this study,the changes of aEEG were monitored,including aEEG normal in 43 cases,mild abnormalities in 33 cases and severe abnor-malities in 14 cases.aEEG monitoring had a higher consistency with HIE grade and cranial MRI examination (Kappa ﹦0.584,P 〈0.001 ;Kappa ﹦0.590,P 〈0.001 ).The sensitivity,specificity,positive predictive val-ue,and negative predictive values of aEEG were high in predicting the severity of HIE.The index of with mild and severe abnormalities of aEEG was significant difference before and after the treatment of hypother-mia(P 〈0.05).Conclusion aEEG has a better evaluation effect on early diagnosis and severity assessing of HIE.Hypothermia can significantly reduce the proportion of abnormal aEEG after HIE,have a neuroprotective effect on the treatment of mild to moderate HIE.

Objective To investigate the related factors effecting the genotoxicity and lipid peroxidation of organic ex-tracts from source water of Huaihe River and its tap water on mice.Methods XAD-II resin was used to absorb the organic chemical pollutants in source water and tap water.The mice were exposed to organic extracts through peritoneal injection continuously for5days.The micronucleus test,the sperm deformity test,the determination of the activities of SOD and GSH-Px and the concentrations of LPO in serum,liver and brain of mice were carried out.Results The fre-quncies of micronuclei and abnormal sperm of mice exposed to organic extracts at dosage of0.01ml/1g(bw)corre-sponding to100L/kg(bw)source water,finished water and tap water increased significantly compared with those of controls(P

Objective To evaluate the effects of propofol and thiopontal on calcium and potassium channels in rat ventricular myocytes and to elucidate the underlying mechanisms of their inhibitory effect on myocardium. Methods Freshly isolated ventricular myocytes were prepared from hearts of rats by trypsin. The effects of propofol and thiopental on L-type calcium current(Ica) and delayed rectifier potassium current(IK)were compared using whole-cell patch clump technique. Results Propofol and thiopontal produced a concentration-dependent inhibition of Ica. Peak concentration of propofol(50 ?mol?L~(-1)) and thiopental(100 ?mol?L~(-1)) during induction of anesthesia decreased Ica by 28% and 46% and shifted the steady-state inactivation curve to more negative voltage, but had no effect on the steady-state activation curve. Propofol and thiopental also decreased IK in a concentration-dependent manner, but the effects of both anesthetics on IK were smaller compared with their effects on Ica. Conclusion The findings of this study suggest that the negative inotropic of propofol and thiopental are, at least in part, related to decrease in Ca~(2+) trans-sarcolemmal current by accelerating L-type calcium channel inactivation. Both anesthetics decrease delayed rectifier potassium current, thus partially antagonizing the effect of decreased calcium current.
