Objective To observe urinary iodine levels in the rat model for excessive iodine intake and monophagia.Methods Wistar rats were randomly divided into 8 groups:normal diet control group(NC),10-fold iodine + normal diet group(10 HI-N),50-fold iodine + normal diet group(50 HI-N),100-fold iodine + normal diet group(100 HI-N),monophagia control group(MC),10-fold iodine + monophagia group(10 HI-M),50-fold iodine + monophagia group(50 HI-M),100-fold iodine + monophagia group(100 HI-M).The excessive iodine intake groups exposed to 1 400,7 600,15 350 ?g/L I-through drinking water presented higher levels of daily iodine intake,which were 10,50,100 times of those in control groups.During the exposure period,the body weights of the rats were measured weekly,the levels of urinary iodine were determined at the second,the fourth and the sixth month.Results The body weights of the excessive iodine intake groups with monophagia were lower than that of the NC group.In normal diet groups and monophagia diet groups,the levels of urinary iodine increased with the increase of iodine intake.The levels of urine iodine in 50 HI-M group and 100 HI-M group were significantly higher than those of the related groups with higher iodine intake.Conclusion The experimental animal model of excessive iodine intake and monophagia are successfully established in the present research,with physical retardation and higher urinary iodine.

Objective To study the effect of vasopressin (VS) on the small bowel circulation and the safety of emboliotherapy for the small intestinal hemorrhage by DSA. Methods Ten dogs were divided into three groups. Vasa recta were ligated 30min after VS infusion ended in group A( n =4), and 2h after VS infusion ended in group B( n =4), they were ligated without VS infusion in control group ( n =2). DSA were performed before and after VS infusion, before and after the ligation. The tested parts of intestine were resected to make the pathologic examination a week late. Results All branches of mesenteric arteries contracted and the contrast developed light in the intestinal wall after VS infusion. Branches contraction recovered but the contrast developed still slight in the intestinal wall about 30min after infusion ended. All manifestation of DSA recovered to normal 2h after infusion ended. In all groups, the blood vessel net can be seen but is fewer and scattered in the area of ligation. The collorate presented soon after the ligation. The pathologic examination proved that there was only mind mucosal ischemia in all groups. Conclusion The repressive effect of VS to the circulation of intestine weakened and then disappeared rapidly after the infusion ended. VS infusion had no significant effect on the safety of emboliotherapy for small intestinal bleeding when the infusion has been finished for more than 2hr. DSA can demonstrated the circulation state of the intestine before and after embolization.

Objective To establish the rapid pathogen identification method for HIV and Mycobac-terium tuberculosis (Mtb)co-infection and the assay for the drug susceptibility. Methods Geneprobe and 16S rDNA sequencing were used to differentiate mycobacterium species and modified microscopic observation drug susceptibility (MODS) was used for the drug susceptibility test. The above assays were compared with acid-fast smear, L-J culture and proportional drug susceptibility tests. Results (1) Thirty-four mycobacte-rial isolates were obtained from 112 samples collected from 68 HIV patients. Among these isolates, the strain species were determined by Geneprobe and 16S rDNA sequencing as the followings: 21 Mtb complex, 10 NTM including 5 M.avium complex, 2 M.gordonae, 2 M.kansasii, 1 M.colombiense, and 3 co-infection. (2) The sensitivity of Mtb to rifampicin, ethambutol, isoniazid and streptomycin were 100%, 100%, 76.2%, 90.5% respectively, while the sensitivity of NTM to rifampicin, ethambutol, isoniazid and strepto-mycin were 40%, 60%, 0%, 30% respectively. There is no significant statistic difference between the two methods, MODS and the reference standard, for the drug susceptibility test. (3) Six to eight weeks are nee-ded for the identification of the species of mycobacteria and the drug susceptibility test by using traditional method. In this study, 5-14 d, 6-15 d and 10-14 d are needed for Geneprobe, 16S rDNA sequencing, and MODS respectively. The time for the testing has been dramatically shortened. Conclusion The identifica-tion of mycobacterial species and the drug susceptibility test using clinical samples could be completed within 15 days by using combined Geneprobe, 16S rDNA sequencing and modified MODS. This combined method can be used for the pathogen identification and drug resistant test in HIV patients who are co-infected by my-cobacteria.

Objective To analyze the epidemiological characteristics of epidemic mumps in Chongqing Wanzhou district,and provide scientific basis for taking effective prevention and control measures.Methods Epidemic data of mumps in Wanzhou district from January 2011 to December 2014 were investigated retrospectively.Results A total of 2 785 cases of epidemic mumps were reported,there was no death case,the incidence of mumps was 44.02/100 000.Incidence of mumps in population under 15 years old was the highest,accounting for 84.45% (2 352/2 785 ).Mumps mainly occurred among students (1 674 cases,60.11 %).The peaks were from April to July and Oc-tober to December,the number of mumps increased significantly from October to December in 2013.Difference in incidence among each year of 2011 -2014 was statistically different(χ2 =40.52,P <0.01).Incidence of mumps was statistically different between the city streets and villages/towns(63.99/100 000 vs 32.13/100 000,χ2 =20.168,P<0.01).Incidence was statistically different between the city streets and villages/ towns each year of 2011 -2014 (all P < 0.01 ),except 2012,the incidence of mumps of city streets was significantly higher than villages/ towns. Conclusion It is important to conduct “Five early”for the prevention and treatment of infectious diseases,strength-en the vaccination of measles-mumps-rubella (MMR)vaccine or vaccine against epidemic mumps,especially the vaccination for students and children in nurseries,popularize the knowledge about prevention and control of mumps, improve diagnosis and treatment level,and strengthen the epidemic monitoring.
