The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.

OBJECTIVE:
To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims.
METHODS:
Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed.
RESULTS:
MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries.
CONCLUSION
A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.

Objective To discuss how to protect the intracranial vertebral artery and posterior inferior cerebellar artery by observing and measuring the intracranial vertebral artery in the surgery adopt far lateral approach. Methods Mimicking far lateral approach, 20 adult cadaveric heads connected to neck fixed with 10% formalin were dissected. Intracranial segment of the vertebral arteries and their main branches were exposed and measured under operating microscope. Results The intracranial vertebral artery joined with the contralateral one into the basilar artery after traveling through the atlanto-occipital sulcus. The relationship between the vertebral artery and the hypoglossal nerve is close. Thirty sides (75%) of the vertebral arteries traveled to pons medulla sulcus in front of the hypoglossal nerve roots and 2 sides (5%) behind the hypoglossal nerve roots, while 8 sides (20%) traveled among the hypoglossal nerve roots; 70% of the vertebral arteries were contacted to the hypoglossal nerve roots, 30% of which compressed the hypoglossal nerve. The main branches of intracranial segment of the vertebral arteries were the posterior inferior cerebellar arteries, the anterior spinal arteries, the posterior meningeal arteries,and some perforating arteries. Posterior inferior cerebellar arteries all originated from the intracranial vertebral artery were the largest vertebral artery's branches; their trip was mostly loop-shaped and they had close relationship with Ⅸ, Ⅹ, Ⅺ cranial nerves. The starting points of the posterior inferior cerebellar arteries were different, even in the same specimen, but most of them originated from the upper 1/3intracranial vertebral artery. No anterior inferior cerebellar artery was noted originated from the vertebral artery in our specimen. Anterior spinal arteries originated from the vertebral arteries joined with the branches of the bilateral vertebral arteries and traveled down through the tortuous anterior median fissure to supply the spinal cord. Conclusion Being familiar with the characteristics and anatomic vertebral arteries variations of the intracranial vertebral artery and its branches can contribute to identify and protect the intracranial segment of the vertebral artery and its main branches in the surgery adopt far-lateral approach.

OBJECTIVELamiophlomis rotata is a common wild herb in Tibetan traditional medicine with important medicinal and economic value. The paper examines the wild distributions, exploitation regime, and situations.
METHODA variety of research methods, such as literature survey, specimens inspection, market information collection in major Chinese herbal markets, questionnaire of herbalists and employers of local governments and institutions, and field quadrat survey and AcrGIS as well, have been used for this work.
RESULTTotal stock of wild resources of L. rotata is ranging from 3 713.49 tons to 6 896.56 tons (2 519-3 314 t in Qinghai, 490-1 414 t in Gansu, 641-1 167 t in Sichuan, and 422-999 t in Tibet, respectively), acceptable harvest quantity of the herb is ranging from 908-1 675 t per year, and actual harvest quantity is 2 520 t annually far beyond the acceptable harvest quantity.
CONCLUSIONHarvesting quantity of L. rotata is far more than that of acceptable, suggesting that utilization pattern of this wild resource plant is unsustainable. L. rotata seems to act as an indicating plant of degraded ecosystem of high-altitude grassland, shrub grassland, and wetland, and distributes in those degraded and degrading plateau ecosystems, and the plant is facing with pressure of ecological protection and wild resource population degradation. Wild population monitoring and standard cultivation are of importance for although they are far from implementation due to shortage of related basic studies.

OBJECTIVETo explore in vivo effects of Qizheng-xiaotong plaster on soft tissue injury in rabbit ears at different periods and to offer theoretical bases for clinical application.
METHODSThe experimental models of soft tissue injury in ears were produced in 10 New Zealand white rabbits, and the ears were divided into three groups at the 1st, 2nd, 3rd week. The normal group and treatment group were given the Qizheng-xiaotong plaster extract, and the model group with normal saline. Microscopic analysis, digital collection system, infrared temperature tester and thickness tester were applied to determine the changes of soft tissue injury in local microcirculation and the temperature change after 0, 0.5, 3 and 5 hours, and swelling change at 1 to 5 days respectively.
RESULTSAt the 3rd hour, blood velocity speeded up in normal group and model group, and it lasted for two hours in model group. As compared with model group, it slowed down to original level in treatment group at the 5th hour and the soft tissue swelling decreased from the 3rd to the 5th day as well.
CONCLUSIONThe application of Qizheng-xiaotong plaster is effective in preventing further soft tissue oedema and haematoma. It can make the soft tissue swelling decreased at chronic stage compared with that at acute stage.
