Objective To introduce a poisoning accident caused by clearing up the disuced bloat pool of green plums. Methods In a certain area in Fujian happened a poisoning accident in which many people poisoned. The site of monitoring was carried out immediately. Results The concentrations of hydrocyanic acid, acetonitrile, methane, and carbon dioxide were very high in the air of the pool. Conclusion The main cause of the poisoning was that the cyanogenic glycosides contained in the nucleolus of the green plums. After broken down, the cyanide was released, and then the cyanide synergistic effect with the asphyxiating gas such as methane and carbon dioxide developed also. Treated the sediment and waste water with bleaching powder and lime, cyanide had been eliminated efficiently.

AIM To explore the antagonistic effect of scutellarin on the liver toxicity of upper limit intake (UL) of Se. METHODS Chemical luminescence was used to determine the scavenging effect of scutellarin on reactive oxygen species (ROS) induced by Na 2SeO 3 in vitro . MDA content, the activities of SOD, CAT, GSH Px and histopathological sections were measured to investigate the effects of scutellarin on Se toxicity in rats. RESULTS In vitro experiment showed the ability of scutellarin to inhibit the generation of ROS effectively. MDA content was significantly decreased, the activities of SOD, CAT and GSH Px were significantly increased and liver injury was alleviated obviously in the UL Se plus scutellarin group as compared to the only UL Se group. CONCLUSION Scutellarin markedly antagonized the liver toxicity of UL Se through scavenging ROS induced by excess Se.

Objective To evaluate sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia.Methods Seventy ASA Ⅰ children were randomly divided into two groups,35 children in every group.Children in group S were appliedsevoflurane inhalation[the minimum alveolar concentration(MAC)of sevoflurane was 1.0-1.5],children in group PK were applied ketamine inhalation and total venous anesthesia of propofol[80μg/(kg·min)]with ketamine[20μg/(kg·min)].Compared the time of anesthesia induction,tracheal catheter extubation,anesthesia recovery between the two groups.The mean arterial pressure(MAP),heart rate,pulse oxygen saturation(SpO_2)during anesthesia were compared.During 2 days after operation,the adverse effects such as nausea and vomit,lower grade of sleep quality were also compared.Results Compared with group PK,the time of anesthesia induction,tracheal catheter extubation and anesthesia recovery in group S were shorter (P<0.05),the incidence of emergence agitation in group S was higher(20.0%,7/35 vs 2.9%,1/35)(P<0.05).But nausea(17.1%,6/35),vomit(31.4%,11/35)and lower grade of sleep quality(54.3%,19/35)were higher in group PK than those in groups(all 2.9%,1/35)at 1 day after operation(P<0.05).The incidence of lower grade of sleep quality at2 days after operation in group PK(14.3%,5/35)was higher than that in group S(0)(P<0.05).Cardiovascular effects of children,such as MAP and heart rate during the period of tracheal catheter extubation in group S was higher than that in group PK.Conclusion Sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia still has some disadvantages,the anesthesia technology is selected by anesthesia method and medicine combination.

Objective To analyze the normal lung dose-volume histogram(DVH) varieties in the former and later period(P1 and P2)of three dimensional conformal radiation therapy(3DCRT) plans and the compound (Pc) plan in non-small cell lung cancer(NSCLC),and to access the feasibility to modify the target volume during the treatment course.Methods Twenty-one NSCLC patients who had received accelerated hyper-frationation 3DCRT in P2 were included in the study.Both of the P1 and P2 plans were redesigned to a total dose of 70 Gy with V20 smaller than 35%.When the target volume was modified and P2 plan was rede signed using accelerated hyper-frationation 3DCRT of 30 Gy after P1 plan of 40 Gy,the Pc plan was compoun ded by transmitting the parameters(such as target volume,irradiation field and dose) of P1 plan into P2 plan. Total lung volume and target volumes(GTV,PTV) of P1 and P2 were evaluated.MLD,V5,V10,V20 and V30 of P1,P2 and Pc were calculated.Results The total lung volume in P1 and P2 plans was not significantly dif ferent(t = 0.19,P = 0.850).The volumes of GTV,PTV in P2 were obviously smaller than P1 (t = 2.88,P = 0.009 ; t = 4.01 ,P = 0.001) .When comparing P2 with P1 ,MLD were 16.5 Gy Vs 17.8 Gy (t = 2.60, DOI:10.3760/cma.j.issn.1004-4221.2009.01.057 P = 0.017),V30 was significantly decreased (t = 2.19,P = 0.041),but V5,V10 and V20 had no significant difference.Similar differences were found in MLD,V5 ,V10 ,V20 and V30 when comparing Po to P1.P2 plans had significantly smaller MLD,Vs,V10,V20 and V30 than Pc plans.Fourteen patients with decreased PTV were further analyzed.The V30 and MLD decreased significantly (t = 3.00,P = 0.0 I 0;t = 2.38,P = 0.033), but V5 ,V10,V20 had no difference when comparing P1 and P2 plans.Among these 14 patients,the V10 and V30 decreased significantly(t = 2.76,P = 0.033 ; t = 3.60,P = 0.011) when P2 plans were generated using the same field number and beam angles in P1 plans in 7 patients.The parameters were similar in P1and Pc plans,but increased significantly when comparing to P2.Various parameters were the same among P1,P2 and Pc plans when P2 plans were designed using 1-2 different fields and angles in the other 7 patients.The differ ences were not significant between P1 and P2 plans in 7 patients with the same or increased PTV.Expansion or contraction of PTV significantly influenced MLD and V2o (r =-0.62,P = 0.03 ; r = O.48,P = 0.029). Conclusions When the tumor regresses,the high dose volume of the lung decreases with modifying the tar get volume and replanning in the later period using accelerated hyper-frationation 3DCRT.The low dose vol ume of the lung may decrease if the field orientations are same throughout the treatment.It is rational to eval uate the normal lung DVH of the whole plan when the physical parameters of the later period plan are the same as the former one.

Objective To identify the key factors triggering medical disputes induced by differences in cognition between doctors and patients in order to control the occurrence and development of medical disputes. Methods From 2002 to 2006,the outpatients,inpatients and medical staff of 3 hospitals in Shanghai(class 3 first level general hospital,n=2;class 3 first level special hospital,n=1) were investigated,and random sampling method was employed for the research analysis. Results There were significant differences between doctors and patients in cognition of influential factors triggering medical disputes such as health law,medical services,rights and obligations. Conclusion The differences in cognition between doctors and patients are important causes for medical disputes,and effective prevention and intervention measures must be taken.

AIM To study the effects of Scutellarin on glutathione peroxidase and thioredoxin reductase gene expression and activities in liver, kidney and testis tissues of rats supplemented with upper limit intake (UL) of Se. METHODS RT PCR and enzyme activities were used to determine GSH Px and TR mRNA levels and activities. RESULTS GSH Px and TR mRNA levels and activities were remarkably decreased in livers of rats supplemented with UL Se. Scutellarin significantly increased GSH Px and TR mRNA levels and activities in livers of rats supplemented with UL Se. No significant effects were found in rats treated with only Scutellarin as compared with the control. There were also no significant effects of UL Se on GSH Px and TR mRNA levels and activities in rat kidney and testis. CONCLUSION Scutellarin effectively antagonized the decrease of GSH Px and TR mRNA levels and activities in rat livers due to supplementation with UL. The effect of UL on GSH Px and TR mRNA levels shows tissue specificity.
