Objective To investigate Insertion/Deletion (InDel) polymorphism on the X chromosome and to screen 18 InDel loci for the Chinese Han population as a forensic DNA typing system auxiliary. Meth-ods Eighteen X-InDel markers were selected using the Human Genome Browser and dbSNP database. Multiplex PCR primer pairs of selected X-InDel markers were designed using Primer 3 software and di-vided into 3 groups according to the amplified fragment length, labeled by FAM, HEX and TAMRA fluorescence dye, respectively. The population genetics research and comparative analysis of Chinese Han nationality and 4 main minorities, the Hui, Wei, Mongol, and Tibetan nationalities, were investigated with the system. Results A new multiplex genotyping system, named InDel X-18PLEX, was successfully developed and validated, consisted of 18 X-InDel markers on the X chromosome and 1 Amelogenin gen-der marker. No deviation from Hardy-Weinberg equilibrium expectations was detected in the distribution of genotypes in the 5 investigated ethnic groups. However, there was significant difference between their distributions. From the investigation of Han nationality, high female (0.999 999 4) and male (0.999 88) overall discrimination power values were obtained, as well as high overall mean exclusion chance values in trios (0.999 992) and in duos (0.99). Conclusion InDel X-18PLEX meets the requirements as a forensic DNA complementary kit, providing effective supplementary analytical tools for difficult cases.

The authors retrospecitviely analyzed the MRI findings of the 8 head-injured patiens who had showed persistent unconsciousness and severe neurologic deficite after trauma. T2-weighted MR images disclosed high signal intensity lesions of various size and shape at lobar white matter and corpus callosum, subcortical gray matter, brain stem, and cerebral cortex, and assisted greatly in understanding the neurologic deficits of the corresponding patients. The lesions were mostly multiple and involved multiple structures. CT's revealed in those patients only small hemorrhages, suspicious low densities, such nonspecific findings as slit ventricles and diffuse brain atrophy, or no abnormality at all. Post-traumatic parenchymatous lesions detected by MR images were either missed or quite underestimated on CT's. MRI was very supeior to CT in the detection and anatomic localization of nonhemorrhagic intraaxial cerebral injuries. especially in the cases of small corical contusions, brainstem and white matter injuries. For the evaluation of the acute posttraumatic patients, CT ios indicated in order to fastly detect intracranial hemagomas which may need emergent surgical evacuation. If CT findings does not explain the neurologic degicits of the patients, especially in the late stage. MRI is indicated. MRI is expected to play a major role in the diagnosis of shear injuries involoving white matter and brainstem where CT has been of little contribution or misleading.

We report a rare case of cervical intradural extramedullary neurilemmoma associated with extradural cavernous angioma in adolescent male patient. This 19-year-old man complained of increasing weakness of left extremities with pain and numbness, starting upwards from the region of left leg since 2 months before, which has aggravated gradually and developed to right side. Neither the patient nor any family member displayed the stigmata of spinal tumor. Neurological examination showed spastic qudriparesis, more severe on left side, disclosed absent vibratory sense and diminution of pain and touch below level of cervico-thoracic junction. Myelogram demonstrated a large filling defect at the C4-6 vertebral level, which was interpreted as an intradural extramedullary or extradural mass. Laminectomy was performed 4 days after admission. At surgery, reddish, diffuse and well demarcated friable mass was found extradural space at the level of C4-6. But post-operative course was not improved for 2 weeks, so we are performed second operation after identified another intradural extramedullary mass by spinal CT. A total removal of tumor mass was accomplished at second procedure. Hostological examination confirmed the diagnosis of cavernous angioma at the extradural mass, neurilemmoma at the intradural extramedullary mass. The post-operative course was satisfactory.

OBJECTIVETo study the polarization and immune regulation of TH cells in patients with bronchial asthma.
METHODSThirty-eight hospitalized children with bronchial asthma (ranging from 4-12 years old) and 29 age-matched healthy children (Control group) were enrolled in this study. Serum IL-2 and IFN-gamma levels were detected using ELISA. The percentage of TH1 and TH2 cells was detected by intracellular staining.
RESULTSThe serum levels of IL-2 (15.94 +/- 3.07 microg/L) and IFN-gamma (487.2 +/- 43.6 pg/mL ) in asthmatic patients were significantly lower than those in the Control group (24.73 +/- 4.37 microg/L and 654.07 +/- 14.64 pg/mL respectively; P < 0.01). The percentage of TH1 in asthmatic patients decreased significantly compared with that in the Control group [(11.24 +/- 2.43)% vs (16.67 +/- 2.73)%; P < 0.01]; in contrast, the percentage of TH2 increased compared with that in the Control group [(19.85 +/- 4.46)% vs (16.08 +/- 6.17)%; P < 0.05].
CONCLUSIONSThe serum levels of IL-2 and IFN-gamma, and the number of TH1 cells decreased in asthmatic patients. The decreased number of TH1 cells and the ratio of TH1/TH2 suggest an abnormal polarization of TH1 and TH2 cells. The changes may be associated with the inhibition of cellular immune function in asthmatic patients.
