Objective To study the significance of Helicobacter pylori (Hp) infection and the expression of caudal-related homeobox transcription factor 2 (CDX2),mucin 2 (MUC2) proteins in gastric cancer,and elucidate the prognostic significance of CDX2,MUC2 proteins in gastric cancer.Methods Ninety cases of gastric cancer were available for the study.Hp was studied by Warthin-Starry bacterium stain and CDX2 and MUC2 proteins were studied by immunohistochemical stain.Results There was no Hp infection and no expression of CDX2 and MUC2 proteins in normal gastric mucosa.The positive rate in the cases of intestinal-type gastric cancer was 67.86%(38/56) for Hp,75.00% (42/56) for CDX2,and 66.07%(37/56) for MUC2,respectively,and it was higher than that in the cases of diffuse-type gastric cancer,which was 35.29%(12/34),41.18%(14/34) and 38.24%(13/34) respectively (P<0.01 or < 0.05).In intestinaltype gastric cancer,the positive rate of CDX2 and MUC2 proteins was also higher in Hp positive cases than that in Hp negative cases,and it was the same as CDX2 protein in diffuse-type gastric cancer.Higher positive rates of CDX2 and MUC2 proteins were observed in the cases of early gastric cancer than those in the cases of advanced gastric cancer (P < 0.01 or < 0.05),also it was observed in the cases of no lymph node metastasis than in the cases of lymph node metastasis (P < 0.01 or < 0.05).Moreover,the positive rate of CDX2 protein in the cases of stage Ⅰ～Ⅱwas higher than that in the cases of stage Ⅲ～Ⅳ (P < 0.05).Conclusions Hp infection and the expression of CDX2 and MUC2 proteins are related with gastric cancer,and has close relationship with intestinal-type gastric cancer.The expressions of CDX2 and MUC2 proteins may inhibit the infiltration and metastasis of gastric cancer.

To study the dynamic changes of CT perfusion parameters during the first 12 h in the embolic cerebral ischemia models. Local cerebral ischemia model were established in 7 New Zealand white rabbits. All CT scans were performed with a GE Lightspeed 16 multislice CT. Following the baseline scan, further CT perfusion scans were performed at the same locations 20 min, 1-6 h and 8, 10 and 12 h after the embolus delivery. Maps of all parameters were obtained by CT perfusion software at each time point. The brains, taken 12 h after the scan, were sliced corresponding to the positions of the CT slices and stained by 2,3,5-triphenyltetrazolium chloride (TTC). On the basis of the TTC results, the ischemic sides were divided into 3 regions: core, penumbra and the relatively normal region. The changes of all parameters were then divided into 3 stages. In the first two hours (the first stage), the CBV dropped more remarkably in the core than in the penumbra but rose slightly in the relatively normal region while the CBF decreased and MTT, TTP extended in all regions to varying degrees. In the 2nd-5th h (the second stage), all the parameters fluctuated slightly around a certain level. In the 5th-12th h (the third stage), the CBV and CBF dropped, and MTT and TTP were prolonged or shortened slightly in the core and penumbra though much notably in the former while the CBV, CBF rose and MTT, TTP were shortened remarkably in the relatively normal region. We experimentally demonstrated that the location and extent of cerebral ischemia could be accurately assessed by CT perfusion imaging. The pathophysiology of the ischemia could be reflected by the CT perfusion to varying degrees.

This study aimed to induce the differentiation of isolated and purified adipose-derived stromal cells (ADSCs) into myoblasts, which may provide a new strategy for tissue engineering in patients with stress urinary incontinence (SUI). ADSCs, isolated and cultured ex vivo, were identified by flow cytometry and induced to differentiate into myoblasts in the presence of an induction solution consisting of DMEM supplemented with 5-azacytidine (5-aza), 5% FBS, and 5% horse serum. Cellular morphology was observed under an inverted microscope. Ultrastructural changes occurring during the differentiation were observed by transmission electron microscopy and confocal laser scanning microscopy. Cellular immunohistochemical staining was applied to determine the expression of desmin protein in cells with and without induced differentiation. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were used to detect mRNA and protein expression, respectively, of sarcomeric and desmin smooth muscle proteins. The results showed that ADSCs were mainly of a spindle or polygon shape. Flow cytometry analysis revealed that ADSCs did not express CD34, CD45, and CD106 but high levels of CD44 and CD90, which confirmed that the cultured cells were indeed ADSCs. After induction with a 5-aza-containing solution, morphological changes in ADSCs, including irregular cell size, were observed. Cells gradually changed from long spindles to polygons and star-shaped cells with microvilli on the cell surface. Many organelles were observed and the cytoplasm was found to contain many mitochondria, rough endoplasmic reticulum (rER), and myofilament-like structures. Cell immunohistochemical staining revealed different levels of desmin expression in each phase of the induction process, with the highest expression level found on day 28 of induction. RT-PCR and Western blot results confirmed significantly higher desmin gene expression in induced cells compared with control cells, but no significant difference between the two groups of cells in sarcomeric protein expression. It was concluded that under specific induction setting, ADSCs can be induced to differentiate into myoblasts, providing a potential new option in stem cell transplantation therapy for SUI.
