[Identification of sibling brothers using STR and Y-biallelic markers].

OBJECTIVE: To explore the methods for identification of sibling brothers with Y-STR locus mutation by detection of genetic markers on autosome and Y-biallelic. METHODS: Goldeneye 20A and 18NC kit were used to genotyped the 35 STRs on autosome from two men. PowerPlex Y kit and Yfiler kit were used to genotyped the 16 STRs on Y chromosome full sibling index was calculated by ITO method. Twenty Y-biallelic markers were genotyped by fragment length discrepant allele specific PCR or general PCR. RESULTS: Relationship of sibling brothers was found to have mutation of 2 loci on 16 Y-STR and the identical genetype of 20 Y-biallelic markers as well as a cumulative full sibling index of 4.3149 x 10(6) from 35 STRs on autosome. CONCLUSION: In identification of paternal linage of Y-STR mutation, more genetic information can be acquired by detection of Y-biallelic markers including SNP and InDel.

[Clinical application of acupuncture for treatment of heroin withdrawal syndrome].

OBJECTIVE: To make technical standard of acupuncture manipulation for acupuncture treatment of heroin withdrawal syndrome. METHODS: Two hundred and twenty cases of heroin withdrawal syndrome were randomly divided into an acupuncture group of 111 cases and a control group of 109 cases. They were respectively treated with acupuncture and oral administration of lofexidine hydrochloride, and their therapeutic effects were observed. RESULTS: The heroin dependence (acute stage) were effectively withdrawn in the two groups. The treatment group in change of total scores for withdrawal symptoms before and after treatment, the total scores for withdrawal symptoms at the 4th and 5th days, treatment of insomnia and the score for self-Hamilton Anxiety Scale and the score after at the 4th day was superior to the control group (P < 0.05, P < 0.01, P < 0.001). CONCLUSION: Acupuncture has a satisfactory, rapid, safe and reliable clinical therapeutic effect.
