In the criminal cases of driving under the influence (DUI), DNA evidence can be collected from the deployed airbag of the motor vehicle and submitted to the crime lab for touch DNA analysis. The evidence can be acquired when the skin cells are observed on the surface of the airbag in a traffic accident. However, the low quantity or quality of the evidence collected from a crime scene prevents further identification analysis in many cases. In the current study, we reported a case of identifying touch DNA extraction from the shed skin cells from the deployed airbag of a motor vehicle. We managed to collect DNA evidence from the shed skin cells in an airbag using a proper approach of collection and extraction. The 5.87 ng of extracted DNA was sufficient for genotyping and forensic identification, which helped to identify the driver of the car in collision with a pier in the street. In DUI cases and other traffic accidents, therefore, the amount of touch DNA extracted from the deployed airbag can be sufficient for DNA marker genotyping and further analysis.

OBJECTIVETo assess the effect-increasing action of rolling needle therapy on insomnia.

METHODSSixty-four cases were randomly divided into a rolling needle treatment group and a control group, 32 cases in each group. The control group were treated with oral administration of clonazepam 4 mg, once each night, for 4 consecutive weeks. The rolling needle therapy group were treated with the same treatment as the control group, plus the rolling needle stimulation of the back. The therapeutic effect was assessed by effective rate of sleep improvement and Pittsburgh sleep quality index (PSQI).

RESULTSAfter treatment there was a significant difference between the two groups in the score of PSQI (P < 0.01).

CONCLUSIONThe rolling needle therapy can increase the improving action of clonazepam on insomnia, and increase life quality of the patient.

Standardized Manipulation of Acupuncture and Moxibustion Part 8: Intradermal Needle was compiled with the following principles. The compiling standard, technical features and clinic manipulations of intradermal needle were taken as the basic principle for compiling. Literature research, expert survey and clinic practice verification were applied as the drafting methods. The key issues were focused on the relationship between standardization and individualization, normalization and effectiveness, qualification and quantification. And the postural selection, reinforcing and reducing manipulations, fixing materials and embedding duration involved in intradermal needling were emphasized particularly. At the same time, details and the future way of thinking of intradermal needle were expounded in this article as well.

OBJECTIVETo investigate the point mutations of mitochondrial DNA in the families with hereditary ataxia.

METHODSPolymerase chain reaction and single strand conformation polymorphism (SSCP) were used to analyze the mitochondrial DNA extracted from human peripheral white blood cells from the families with HA and 35 normal controls. Sequencing was performed to search the point mutations in mitochondrial DNA of those subjects whose results of SSCP were abnormal.

RESULTSA mitochondrial DNA point mutation 11893(A>G) was identified in 2 patients and 1 family member without symptoms.

CONCLUSIONA new point mutation 11893(A>G) of detected mitochondrial DNA may be relative to hereditary ataxia.

BACKGROUNDParkinson's disease (PD) is an autosomally inherited neurodegenerative disease in elderly people. The etiology of PD has long been thought to be associated with both genetic and environmental factors. To explore potential genetic risk factors for PD in the northern Han Chinese population, we investigated three single nucleotide polymorphisms (SNPs) (rs4538475, rs11107 and rs12564040) in the BST1, PARK15 and PARK9 genes.

METHODSGenomic DNA from 215 PD patients and 212 matched controls was amplified in two independent PCR systems and subsequently genotyped by digestion with the endonuclease PstI. Genetic parameter and association studies were carried out with SPSS 13.0 and PLINK 1.07 software.

RESULTSWe could accurately detect all genotypes in the three loci with the PCR-RFLP or mismatched PCR-RFLP techniques. The observed heterozygosities of the rs4538475 and rs11107 loci in PD and control groups ranged from 0.460 - 0.481 and 0.410 - 0.441, in BST1, PARK15 respectively, while we detected no heterozygosity at the rs12564040 locus in PARK9. The similar distributions of genotypic frequency between both groups suggest that the three SNPs investigated in this study are unlikely to play roles as common risk factors or pathogenic mutations for PD in northern Han Chinese.

CONCLUSIONThe SNPs investigated in the BST1, PARK15 and PARK9 genes associated with PD susceptibility are not associated with PD in the northern Han Chinese population.

OBJECTIVETo investigate the tumor-associated antigen CA125 expression in the serum and cervical and vaginal secretions in women during normal reproductive period, and explore the clinical value of detecting tumor markers in the cervical and vaginal secretions.

METHODSA total of 145 women in reproductive period were divided into 3 age groups (20-29 years, 30-39 years, and over 40 years), and their CA125 levels in cervical secretion, vaginal secretion and serum were detected by automatic electro-chemiluminescent immunoassay.

RESULTSCA125 levels in the cervical secretion, vaginal secretion and serum showed no significant difference between the 3 age groups (P>0.05). In each group, CA125 levels differed significantly between the cervical secretion, vaginal secretion and serum (P<0.001). In the 145 women, the average CA125 level was 497.82 - or + 75.29 U/ml in the cervical secretion, 114.66 - or + 26.40 U/ml in vaginal secretion and 18.06 - or + 3.35 U/ml in serum, showing significant differences between them (P<0.001).

CONCLUSIONCA125 expression level is significantly higher in the cervical and vaginal secretions than in the serum in women in normal reproductive period, and its levels in cervical and vaginal secretions can be more sensitive and convenient for early detection of related diseases.

The aim of this study was to investigate the parameters of gene frequencies, haplotype frequencies and linkage disequilibrium of HLA-A, -B, -Cw in HLA classical I loci for Chinese Han population. HLA-A, HLA-B and HLA-Cw loci were genotyped in 1014 unrelated China people using low resolution PCR-SSP typing method, and their genetic parameters were analyzed by statistic methods. The results indicated that among all the detected HLA-I genes, A*02 (0.33), A*11 (0.24), B*15 (0.14), B*13 (0.13), Cw*03 (0.25) and Cw*07 (0.18) were the popular gene groups distributing in Chinese Han population, and A*02-B*46 (0.071), A*11-B*15 (0.051), A*02-Cw*01 (0.084), A*11-Cw*03 (0.079), B*46-Cw*01 (0.095) and B*13-Cw*03 (0.071) were the predominant haplotypes in Han population. Additionally, A*02-B*46, A*30-B*13, A*30-Cw*06, A*02-Cw*01, B*46-Cw*01 and B*58-Cw*03 were statistically significant with strong linkage disequilibrium. While A*02-B*15, A*02-B*40, A*24-Cw*03, A*02-Cw*03 and A*31-Cw*03 were in low linkage disequilibrium, among them A*24-Cw*03 appeared frequently in HLA recombination events. In addition, A*02-B*46-Cw*01 (0.075), A*30-B*13-Cw*06 (0.046), A*11-B*13-Cw*03 (0.045), A*33-B*58-Cw*03 (0.044), A*11-B*15-Cw*08 (0.027), A*02-B*38-Cw*07 (0.023) and A*11-B*40-Cw*07 (0.022) were the main extended haplotypes in Han population. In conclusions, this study investigated systematically the genetic polymorphism features of Chinese Han population, which may provide useful genetic parameters for researches in colonial evolution, clinical transplantation and disease susceptibility.
