Objective To investigate the effect and possible mechanism of erlotinib,an epidermal growth factor recceptor inhibitor,on human pancreatic cancer cell lines BxPC3 in vitro.Methods Methyhhiazolyhetrazolium(MTT)assay was used to detected the proliferation of BxPC3 after exposure to erlotinib,apoptosis and cell cycle changes were studied by flow eytometry and terminal deoxynucleotidyl transferase-mediated nick end labeling assay(TUNEL).The expressions of bcl-2 mRNA,bax mRNA,bcl-xL mRNA and bak mRNA were determined by reverse transcriptase polymerase chain reaction(RT-PCR). Results Edotinib inhibited BxPC3 cells growth in a dose and time dependent manner in vitro.The cell viabilities in erlotinib 1 μmol/L and 100 μmol/L groups 72 h later were(90.25 ±2.62)%and(40.75 ±2.98)%,and the difference was statistically significant(P<0.01).The cell viability in edotinib 50 μmol/L groups 24 h and 96 h after BxPC3 exposure were(74.0±4.08)%and(49.50 ±1.29)%,and the difference was statistically significant(P<0.01).Cell apoptosis rate in erlotinib 50 μmol/L group was(11.0 μ1.1)%,which was significantly higher than(6.2 ±1.1)%in control group(P<0.01).G_0/G_1 cell accounted for (73.4±1.3)%of all the cells,which was significantly higher than(63.3 ±1.O)%in control group.With transmission electron microscope,the morphology of BxPC3 ceils showed typical apoptosis and apoptotic body. The expressions of bcl-2 mRNA,bel-xl mRNA were down-regulated,while the expression of bax mRNA was slightly up-regulated,and the expression of bak mRNA was not affected.Conclusions The growth of BxPC3 cells could be suppressed by erlotinib and possible mechanisms involved blocking cell cycle,up-regulating apoptosis proteins and down-regulating apoptosis inhibitor proteins.

Objective To study CT value of diagnosis and identified diagnosis in osteolytic metastases of the vertebral column through describing their CT manifestation.Methods In 46 patients, 72 vertebrae osteolytic metastases were analyzed and compared with X-ray findings of 28 cases.Results In 72 vertebrae osteolytic metastases, there were destruction of 74 corpus vertebrae in 45 patients, of pediculus arcus vertebraes in 22 cases, of processus transverses in 15 cases, of processus spinosus in 11 cases and lamina vertebrae in 11 cases. Micrometastases were concentrated in corpus vertebrae(45/49). CT found the rate of bone-destruction, affection of vertebrae canal and soft tissue around vertebrae were 100%, 67.8% and 71.4%, but the corresponding rates were only 53.6%, 14.3% and 32.1% by X-ray. Conclusion Vertebral column metastases destructed corpus vertebrae at first, vertebral metastases are the origin or base of destruction of the pediculus arcus vertebrae, lamina vertebrae, processus transverses and processus spinous. CT scanning is more sensitive in finding and evaluating the lesions than X-ray plain film.

Objective To observe the effect of moxibustion on the proliferation of neural stem cells after cerebral ischemia- reperfusion in rat models.Method The middle cerebral artery occlusion (MCAO) model was developed by using modified Zea-Longa method. Seventy-two Wistar rats were randomized into group A (sham-operation group), group B (model group) and group C (moxibustion group). Each group was then further divided into 4 sub-groups according to different time points: 3 d, 7 d, 14 d, and 21 d, 6 rats in each sub-group. For each group, Baihui (GV 20) and bilateral Taiyang (EX-HN 5) were selected to study. The proliferated cells were marked by intraperitoneal injection of BrdU, and TTC staining and HE staining were adopted to detect the pathological changes of brain tissues after cerebral ischemia-reperfusion. Immunohistochemical method was used to dynamically detect the positive expressions of BrdU and Nestin cells in DG and SVZ zones at different time points, and microscope image analysis was taken to study the positive expressions.Result The neurological deficit score in group C was significantly lower than that in group B at each time point (P<0.05). The neurological deficit score in group C was significantly different from that in group B at the same time point (P<0.05). Moxibustion can up-regulate the expression of BrdU in SVZ and DG, and the increase started from the 3rd day and reached the peak on the 7th day. The increase of BrdU expression in group C was more significant than that in group B (P<0.05). Moxibustion can up-regulate the expression of Nestin in SVZ and DG, and the increase started from the 3rd day and reached the peak on the 7th day. The increase of Nestin expression in group C was more significant than that in group B (P<0.05).Conclusion Moxibustion can remarkably promote the recovery of nerve function and the proliferation of BrdU and Nestin after cerebral ischemia-reperfusion in rats.
