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.

Objective To evaluate the clinical value and the early therapeutic efficacy of hysteromyomas treated with the radiofrequency ablation (RFA) by two-dimensional contrast-enhanced ultrasound(2D-CEUS) and three-dimensional contrast-enhanced ultrasound(3D-CEUS). Methods A total of 90 patients with 150 hysteromyomas were treated with RFA, including 138 intramural myomas and 12 submucous myomas (in which 5 had micr-pedicles). 2D-CEUS and 3D-CEUS were performed within one day before and after RFA treatment, respectively. The blood supply of focal zone(FZ) was observed by 2D-CEUS and 3D-CEUS. The volume of hysteromyomas and the coagulation necrosis range were measured by 3D-CEUS. The average necrotic rates of hysteromyoma were calculated. Results The 5 submucous myomas with micr-pedicles were removed completely after the RFA treatment. The 2D-CEUS appearances of other 145 hysteromyomas were diverse after the RFA treatment, in which 137 FZs had no contrast infusion,indicating complete ablation, 8 FZs appeared peripheral linear or small flaky enhancement, considering incomplete treatment. The 3D-CEUS performances were variant too, in which 132 FZs vascular network displayed as a "cavity", indicating complete tumor necrosis, the other 7 FZs appeared "branch shape" low enhancement and another 6 FZs showed nonuniform low enhancement, considering residual tumor tissue. The average necrotic rate of the 139 hysteromyomas was (97.1 ± 12. 9)% ,another 6 hysteromyomas was only (46. 4 ± 7. 0) %. Conclusions 3D-CEUS can display vascular structure and spatial relationship of the hysteromyomas, which can be used as the complement of 2D-CEUS. The combination of the two techniques can evaluate the earlier therapeutic efficacy of hysteromyomas by RFA more timely, intuitively and accurately.

Objective To demonstrate the diffusion tensor imaging(DTI)characteristics of multiple sclerosis(MS)plaques,periplaque white matter regions and normal appearing white matter (NAWM)regions in patients with MS,and to evaluate the clinical values of DTI and three-dimensional brain fiber tracking for the diagnosis of MS.Methods Conventional MRI and DTI were performed in 32 patients with MS and 32 age-matched control subjects.Fractional anisotropy(FA)and apparent diffusion coefficient(ADC)maps were generated and coregistered with T_2-weighted MR images,FA and ADC values were calculated in regions of interest in plaques,periplaque white matter regions,NAWM regions and white matter regions in control subjects.And three-dimensional brain fiber tracking maps were generated by using the DTI.Results TheADCwas(1.233?0.119)?10~(-3)mm~2/s in MS plaques,(0.973?0.098)?10~(-3) mm~2/s in periplaque white matter regions,(0.748?0.089)?10~(-3)mm~2/s in NAWM,and(0.620? 0.094)?10~(-3)mm~2/s in control subjects.The FA was 0.225?0.052 in MS plaques,0.311?0.050 in perip]aque white matter regions,0.421?0.070 in NAWM,and 0.476?0.069 in control subjects. Significant differences in FA and ADC values were observed among all white matter regions(P

· AIM: To report a rare case of mesenchymalchondrosarcoma in the orbit and to explore its clinicmanifestations, pathologic characters, management andprognosis. · METHODS: We report a case of mesenchymalchondrosarcoma of the orbit. The clinical materials,including ophthalmological examination, computed tomo-graphy scan of the orbit, histopathology and immunohis-tochemistry of the biopsy specimen was reported, and itspertinent literatures were reviewed.· RESULTS: A 36-year-old female was seen with proptosisand decreased vision. Histopathology demonstrated anadmixture of undifferentiated mesenchymal cells andislands of mature hyaline cartilage. Immunohistochemicalstudies revealed positivity for vimentin and S-100, whichwas consistent with the diagnosis of mesenchymalchondrosarcoma.· CONCLUSION: Mesenchymal chondrosarcoma in theorbit is extremely rare malignant tumor. Multi-modalitytreatments (surgery, chemotherapy and radiotherapy)may lead to long-term survival.

· AIM: To investigate whether heat shock protein 27 (HSP27) is induced in retinal ganglion cells (RGCs) in experimental rat glaucoma and whether the induction of HSP27 by intraocular pressure (IOP) elevation can increase serum autoantibody to HSP27 in the model.IOP elevation、Sham and normal groups by SPSS12.0. IOP was raised by electrocoagulating at least 3 episcleral veins and limbal veins on the right eye of each rat in IOP elevation group and its contralateral eye was used as controls. Immunohistochemical staining for HSP27 was performed in RGCs and retinal nerve fiber layer (RNFL) and serum immunoreactivity against HSP27 was detected by means of enzyme-linked immunosorbent assay (ELISA) in three groups.RNFL of the eyes with IOP elevation, while it was expressed weakly in untreated control eyes. Compared with sham and normal groups, serum autoantibody to HSP27 was slightly high at 1wk (P ＞0.05) and significantly increased at 2, 3, 4 and 8wk (P＜0.05) in IOP elevation group.enhanced expression of the endogenous HSP27 might play an important role in glaucomatous optic neuropathy.

AIM: To study the experimental method of inducing the chronic intraocular hypertension in rat eyes.METHODS: Twenty Wistar rats were randomly divided into ocular hypertension and Sham control groups. Intraocular pressure (IOP) was raised by electrocoagulating at least 3 episcleral and limbal veins on the right eye of each rat in ocular hypertension group and its contralateral eye was used as control. At 1, 2, 3, 4 and 8wk after the electrocoagulation of the veins, IOP were measured. RESULTS: The treatment of electrocoagulation caused a significant IOP increase of the right eyes over the baseline, over the contralateral eyes, and over the sham control eyes (repeated measures ANOVA, P＜0.001). At 1wk,IOP was (30.12± 5.L8 ) mmHg (1kPa=7.5mmHg), and maintained the high IOP up to 8wk.CONCLUSION: The chronic intraocular hypertension model could be successfully created by electrocoagulating three or more episcleral and limbal veins.
