ABSTRACT
BACKGROUND: Echinococcosis alveolaris were not easily discovered in prophasel Although used various kinds of imaging and immunity test, misdiagnosis rate of echinococcosis alveolaris was still high.OBJECTIVE: To study radioimmunoimaging of ~(131)Ⅰ-labelled anti-alveolar hydatid polyclonal antibody in the rat model with Echinococcus multilocularis in vivo.METHODS: Totally 36 Wistar rats were randomly divided into 3 groups. A group included 12 alveolar echinococcosis rats, B group included 12 normal rats, C group included 12 alveolar echinococcosis rats. Rats in the A and B group were injected intrapedtoneally 1 mL ~(131)Ⅰ-labelled anti-alveolar echinococcosis polyclonal antibodies (37 MBq), those in the C group were injected intraperitoneally I mL ~(131)Ⅰ-(37 MBq). All rats were imaged 24, 48, 72, 96 hours later with ECT to measure region of interest (ROI) of alveolar hydatid. The unit weight radioactive counts per minute of three group rats organs were measured after 96 hours, and the targetto-nontarget (TINT) ratios were calculated in A group rats.RESULTS AND CONCLUSION: In A group rat inoculated right lobe of liver alveolar echinococcosis, radioactive parts of the distribution could be seen. And ROI of alveolar echinococcosis were the highest at 72 hours. After dissection the locations were in line, and it was no significant radioactive liver distdbution in B and C group. Rats were sacrified after 96 hours, in vitro determination of radioactive counts show that A group echinococcus multilocularis was (18.610±3.401)x10~3 cpm/g, which was greater than organs except thyroid and gastric tissues (P ＜ 0.001). The rest of organize T/NT ratios were greater than 1.28 apart from the thyroid and gastric tissues. The difference of unit weight radioactive counts per minute of three group had no obviously significance except the polypide tissues (P ＞ 0.05). This proves that ~(131)Ⅰ-1abelled anti-alveolar echinococcosis polyclonal antibodY successfully combinated with alveolar echinococcosis.
ABSTRACT
Objective To analyse the relationship between Calpain10 gene UCSNP43 and UCSNP44 poly morphisms and diabetes in familial type 2 diabetes mellitus of Uygur in Xinjiang.Methods Sixty-two Uygur type 2 diabetic families were enrolled.The polymorphisms of Calpain10 gene UCSNP43 and UCSNP44 were measured by SNP-stream of gene chip.Results (1) The heritability of the first degree relative and the second degree relative in Uygur familial type 2 diabetes were 0.578 and 0.032.(2)There was no difference between UCSNP43 and UCSNP44 polymorphisms of the first and second degree relatives in familial type 2 diabetes mellitus.(3)The carriers of USCNP43 AA genotype had higher body mass index and fasting insulin than GG and GA genotypes carriers.Conclu sion With the downgrading of the familial relationship,the heritability of type 2 diabetes mellitus was decreasing. The carriers of UCSNP43 AA genotype might have higher insulin resistance than those with GG and AG genotypes.
