OBJECTIVE:
A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father.
METHODS:
Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5.
RESULTS:
According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father.
CONCLUSION
It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.

Journal of Forensic Medicine 2016;32(2):109-113
OBJECTIVE:
To establish the rapid PCR amplification program and system and to verify the technical indexes.
METHODS:
PCR multiplex and capillary electrophoresis detection of 24 autosomal STR loci and one Y-STR loci using the 6-color fluorescence marking technology, as well as A melogenin and Y-InDel. Meanwhile, sensitivity, specificity, identity, stability, mixing and a batch of sample tests were investigated, and the genotype of various routine samples and degraded, exfoliated cell samples were observed.
RESULTS:
The sensitivity of the system was 0.062 5 ng. In addition, the genotype could be detected accurately only around 65 min via rapid amplification. The species-specificity was high and the genotyping of all kinds of dry blood specimens of filter paper and mixed, degraded, exfoliated cell samples were accurate.
CONCLUSION
The rapid amplification system can significantly improve the detection rate, and obtain accurate and stable genotyping results, which may be important implications for the establishment of STR database and study on population genetics and forensic identification.

OBJECTIVETo investigate the protection effects of electroacupuncture on injury of lipid peroxidation induced by liver ischemia in septic rats.
METHODSForty-eight male SD rats were subjected to sepsis induced by cecal ligation and puncture (CLP), and were randomly divided into a Sham operation group (group A), a CLP model group (group B), a CLP model plus electroacupuncture at "Zusanli" (ST 36) group (group C), a CLP model plus electroacupuncture at the shame acupoint (group D), a vagotomy plus CLP model group (group E) and CLP model plus electroacupuncture group after vagotomy (group F), 8 rats in each group. CLP was performed in group E and group F after the abdominal vagotomy. Bilateral "Zusanli"(ST 36) points and the shame acupoint were electroacupunctured (2 mA, 2/100 Hz) for 1 hour in group C, group F and group D, respectively. The hepatic blood flow (HBF) was detected by a laser-Doppler flowmetry at 6 h after CLP. The plasma activity of alanine aminotransferase (ALT) was also determined and specimens of liver were harvested for evaluation of malondialdehyde (MDA), xanthine oxidase (XOD) and assessment of the rate of water content.
RESULTSThe blood flow of the liver was (56.97 +/- 11.95) U in group C which was significantly lower than (80.12 +/- 19.57) U in group A but higher than (42.61 +/- 10.97) U in group B, (44.53 +/- 9.23) U in group D, (30.05 +/- 4.46) U in group E and (30.46 +/- 6.38) U in group F (all P < 0.05) 6 h after CLP. Meanwhile, the levels of MDA, XOD, ALT and the rates of water content in liver in group C were all significantly higher than those in group A, but lower than those in the other four groups (all P < 0.05). The levels of MDA, XOD, ALT and the rates of water content in liver in group E and group F were all significantly higher than those in group D (all P < 0.05), while the blood flow of the liver lower than that in group D (P < 0.05), and with no significant differences in all above measurements between group E and group F (all P > 0. 05).
CONCLUSIONElectroacupuncture at "Zusanli" (ST 36) can promote hepatic blood flow, inhibit lipid peroxidation and alleviate hepatic edema and dysfunction in septic rats, which might be related with the completeness of cranial nerve.

Polyamidoamine-polyethylene glycol (PAMAM-PEG) copolymers were synthesized using IPDI as coupling reagent by two-step method. The copolymers were characterized by IR spectrum and 1H NMR spectrum, and the PEG conjugating ratios of the copolymers were calculated equal to 10% and 30% separately. MTT assay indicated that after PEGylation a lower cytotoxicity of the copolymers could be found, and with increasing PEG conjugating ratio the cytotoxicity decreased obviously. Agarose gel retardation assay demonstrated that PAMAM-PEG copolymers could be combined with DNA and PAMAM-PEG/DNA complexes were prepared by self-assembly. DLS measurement showed that when N/P > or = 50, the particle size of copolymer/ gene complexes was in a range of 150-200 nm, and the zeta potential was in a range of 10-25 mV. In vitro gene transfection illustrated that when N/P < or = 50, the gene transfection efficiency of PAMAM-PEG copolymers was a little less than that of PAMAM-G5, but the transfection efficiency can be raised by increasing N/P ratio or transfection time. Considering both cytotoxicity and transfection efficiency aspects PAMAM-PEG-13 was more effect than PAMAM-PEG-39 in PEGylation.

OBJECTIVETo obtain the polymorphism data of six short tandem repeat (STR) loci, i.e. D9S925, D11S2368, D14S608, D15S659, D17S1290 and D20S470, in Chinese Han population in Shanxi province, and to evaluate the usefulness of the polymorphism data in forensic science.
METHODSThe D9S925, D11S2368, D14S608, D17S1290 and D20S470 primers were synthesized according to GenBank, while the D15S659 primers were self-designed. These primers were used to amplify DNA from 194 unrelated individuals collected from Shanxi Han population. Then the amplified fragments were separated by electrophoresis in 3130 Genetic Analyzer. GeneMapper3.2 software was used to analyze the results.
RESULTSThe distributions of genotypes for the six STR loci were in accordance with Hardy-Weinberg equilibrium. The polymorphism information content (PIC) of the six STR loci were from 0.750 to 0.860, and the heterozygosity ranged from 0.756 to 0.894, and the discrimination power were from 0.920 to 0.965, and the probability of exclusion were from 0.519 to 0.784. The combined probability of exclusion and the combined discrimination power were 0.9988 and 0.99999998, respectively.
CONCLUSIONThe data indicated that D9S925, D11S2368, D14S608, D15S659, D17S1290 and D20S470 loci have high probability of exclusion and discrimination power. They can be used as genetic markers in forensic test and personal identification.

Chinese Journal of Medical Genetics 2008;25(4):477-482
OBJECTIVETo investigate the genetic polymorphisms of 11 Y-chromosomal short tandem repeats (STR) loci in Chongqing Tujia population, and to evaluate their forensic application values and genetic relationships with the other 16 populations of China.
METHODSEleven Y-STR loci in 215 unrelated Tujia individuals from Chongqing were amplified with PowerPlex Y System, and the PCR products were analyzed by 310 Genetic Analyzer. Cluster analysis and phylogenic trees were applied to show the genetic distance among the populations.
RESULTSA total of 195 haplotypes were identified and the overall haplotypes diversity for the 11 Y-STR loci was 0.9942. The gene diversity values (GD) for each locus ranged from 0.3757 (DYS391) to 0.9170 (DYS385a/b). Comparing with other 16 populations, the genetic distance between Tujia and Tibetan was the nearest (0.02467), that between the Tujia and Korean ethnic groups was the farthest (0.25350).
CONCLUSIONThe genetic distribution of the 11 Y-STR loci in Chongqing Tujia population showed favorable polymorphisms. They are suitable for forensic identification and paternity testing in the local area. The study of genetic diversity among different populations is useful in understanding their origins, migrations and their relationships.
