Hijack terror is one of the most common terror attacks. In this paper, the definition, the present condition and future development of hijack terror are elucidated. Hijack terrorism may seriously endanger human lives, result in great economic loss, create social panic and political tumult. The medical succor for hijack terror includes treatment and transportation of the wounded, sanitation for epidemic prevention, protection from harmful agents, and medical health care. The challenges confronting medical support for hijach terror are its unexpectedness and abruptness, complexity, and arduousness in its implementation. In order to negotiate these challenges, it is imperative that a flawless counterplan should be worked out, a highly efficient counterterrorism medical organization should be established, intense emphasis should be paid in the studies of anti-neuclear, antimbiological and anti-chemical warfores, and education for psychological prepuredness should be stressed.

Objective To search for a better way than DSA to display the bronchial arterial (BA) supply of spinal cord, esophagus, trachea, etc., and for further evaluation of BA supply to the above structures, along with reducing the complications of trans-BA infusion and/or embolization. Methods Multislice CT angiography of BA (BA-MSCTA) was performed on 19 patients suffering from lung cancer or hemoptysis due to bronchiectasis after undergoing digital subtraction angiography BA (BA-DSA). Totally 10ml of 45% contrast medium was injected into BA (1～2 ml/s), BA-MSCTA was started 5 s after the injection, scanning from low cervical region to the bottom of lung (collimation: 5 mm; no overlapping reconstruction ). The intra-spinal canal, esophagus, trachea, etc. were enhanced. Results On BA-DSA, except one case in which a bronchial artery was faintly displayed, no spinal artery, intra-spinal canal, esophagus or trachea enhancement could be demonstrated. While on BA-MSCTA, intra-spinal canal associated with an intercostobronchial trunk enhancement due to truncus formation were observed in seven cases, including five cases of spinal enhancement (5/19,26.3%). 15 cases of esophageal enhancement and 18 cases of tracheal enhancement were also observed. Conclusion BA-CTA is superior to BA-DSA in displaying the BA supply of spinal cord, esophagus, trachea, etc.. Spinal arteries are more likely to appear in intercostobronchial truncus cases.

Objective To provide an approach to research of peroxisome proliferator activated receptor (PPAR) ? 2 function, mouse PPAR? 2 (mPPAR? 2) gene was cloned and its transient expression in eukaryotic cells was carried out. Methods mPPAR? 2 mRNA from epididymis fat pad of Chinese Kunming mice was amplified by RT PCR and subcloned into plasmid pcDNA3 to generate the recombinant plasmid pcDNA3/mPPAR? 2 which was confirmed to contain the amplified target gene segments with fluorescence sequencing. The recombinant plasmid pcDNA3/mPPAR? 2 was used to transfect COS 7 with lipofectamine and the expressing product was detected with immune fluorescence assay and Western blot. Results The sequencing results for amplified target gene showed that the sequence of mPPAR? 2 from epididymis fat pad of Chinese Kunming mice is similar to that of mouse PPAR? 2 in Genbank, only at the site of 383 amino acid where Ser (AGC) substitutes Asn (AAC). pcDNA3/mPPAR? 2 was efficiently expressed in eukaryotic cells in vitro. Conclusion This work is the experimental basis for further researching on PPAR? 2 function.

Objective To express the mouse peroxisome proliferator activated receptor ? 2 (mPPAR? 2) in NIH3T3 cells induced by the recombinant retrovirus vector. Methods mPPAR? 2 gene digested from the recombinant plasmid pcDNA3/mPPAR? 2 containing the target gene segment was subcloned into retrovirus vector pGCEN to generate the recombinant retrovirus pGCEN/mPPAR? 2. The recombinant retrovirus pGCEN/mPPAR? 2 and pGCEN were used to transfect PA317 cells with LipofectAMINE, and anti G418 clones of PA317 cells were selected and viral supernatants were harvested and used to infect NIH3T3 cells. The expressing products were identified with immune flurescence assay (IFA) and Western Blot. Results The recombinant retrovirus pGCEN/mPPAR? 2 was constructed, and 5?10 4 CFU/ml and 6?10 5 CFU/ml of pGCEN/mPPAR? 2 containing and pGCEN containing viral supernatants were obtained respectively. mPPAR? 2 was expressed in NIH3T3 cells mediated by the recombinant retrovirus vector. Conclusion This work is the basis for the foundation of adipocyte differentiation model in vitro and further researching on the molecular mechanism of adipocyte differentiation induced by PPAR? 2.

Objective To investigate the value of multislice spiral CT in evaluating the parametrial invasion of cervical carcinoma. Methods 75 cases of FIGO staging II cervical carcinoma who had received the surgery were studied. Their imaging and the FIGO staging were analyzed retrospectively. Results For FIGO staging, the accuracy for evaluating the parametrial invasion was 53.3%(40/75), the rate of underestimation was 26.7%(20/75), the rate of overestimation was 20.0%(15/75); For CT, the accuracy of evaluating the parametrial invasion was 69.3%(52/75), the rate of underestimation was 14.7%(11/75), the rate of overestimation was 17.3%(13/75). In 40 cases, both FIGO staging and evaluation by CT were consistent with the surgical results. In 35 cases, FIGO staging was different from the surgical results. In 29 cases, evaluation by CT was different from the surgical results. In 10 cases, CT could correct the error of FIGO staging. Conclusion CT scan can acquire the multi-plane image, and can directly reflect the parametrial space. It is more accurate than FIGO staging, and is an important complement to FIGO staging.
