Abstract
This study aims to establish rabbit, rat and human models of primary airway fibroblasts, improve existing culture methods of human, and provide alternatives to benign airway stenosis in vitro. We used conventional «tissue adherent method» to culture airway primary fibroblasts extracted from New Zealand rabbits, Sprague—Dawley (SD) rats and human subjects. To improve quality of this culture, we combined the «tissue adherent method» with « trypsinization", and compared the success rate of the two approaches. Cultures were examined using an inverted microscope, following hematoxylin—eosin and immunohistochemical staining. The different species were identified based on the total number of chromosomes. We successfully cultured primary airway fibroblasts isolated from three species. Human airway primary fibroblasts are more difficult to culture. The efficiency of culture is low, when using the «tissue adherent method». However, the rate of successful culture is improved when combined with the "trypsinization", and by using the «serum adherent, organizing tablet» technology. In conclusion, we demonstrate that primary airway fibroblasts from three mammalian species can be cultured successfully in vitro, for a reliable cellular model of benign airway stenosis. Culturing human primary airway fibroblasts is technically more challenging than the other two species. It is necessary to improve it.

Abstract
BACKGROUND Colonic migrating motor complexes in the rat constitute two distinct propulsive motor patterns, pan-colonic rhythmic long distance contractions (LDCs), and rhythmic propulsive motor complexes (RPMCs) occurring primarily in the mid/distal colon. Interstitial cells of Cajal govern their rhythmicity, but their occurrence is dependent on neural programs. Our aim was to investigate the involvement of 5-HT3 and 5-HT4 receptors in the generation and pharmacological control of the motor patterns. METHODS Effects of 5-HT-related drugs on colonic motor patterns were analyzed through spatio-temporal maps created from video recordings of whole organ motility. KEY RESULTS 5-HT3 antagonists abolished RPMCs and LDCs. 5-HT4 agonists inhibited LDCs; they promoted RPMCs, which was blocked by the 5-HT4 antagonist GR 125487. 5-HT and the 5-HT3 agonist m-CPBG strongly inhibited LDCs and RPMCs. CONCLUSIONS & INFERENCES The generation of LDCs involves ongoing 5-HT release acting on 5-HT3 and 5-HT4 receptors. The spontaneous generation of RPMCs involves ongoing 5-HT release acting on 5-HT3 but not 5-HT4 receptors. Prucalopride and mosapride promote RPMCs, an effect that is inhibited by the 5-HT4 receptor antagonist GR 125487. A 5-HT3 agonist does not promote RPMCs. Segmentation, including a pattern of sequential segmental activity not previously described, can occur without significant involvement of 5-HT3 and 5-HT4 receptors. 5-HT and a 5-HT3 agonist are strongly inhibitory indicating that 5-HT receptors are present in inhibitory pathways which are normally not involved in the generation of spontaneous or distention-induced motor patterns.

Abstract
The ability to integrate environmental and developmental signals with physiological responses is critical for plant survival. How this integration is done, particularly through posttranscriptional control of gene expression, is poorly understood. Previously, it was found that the 30 kD subunit of Arabidopsis cleavage and polyadenylation specificity factor (AtCPSF30) is a calmodulin-regulated RNA-binding protein. Here we demonstrated that mutant plants (oxt6) deficient in AtCPSF30 possess a novel range of phenotypes--reduced fertility, reduced lateral root formation, and altered sensitivities to oxidative stress and a number of plant hormones (auxin, cytokinin, gibberellic acid, and ACC). While the wild-type AtCPSF30 (C30G) was able to restore normal growth and responses, a mutant AtCPSF30 protein incapable of interacting with calmodulin (C30GM) could only restore wild-type fertility and responses to oxidative stress and ACC. Thus, the interaction with calmodulin is important for part of AtCPSF30 functions in the plant. Global poly(A) site analysis showed that the C30G and C30GM proteins can restore wild-type poly(A) site choice to the oxt6 mutant. Genes associated with hormone metabolism and auxin responses are also affected by the oxt6 mutation. Moreover, 19 genes that are linked with calmodulin-dependent CPSF30 functions, were identified through genome-wide expression analysis. These data, in conjunction with previous results from the analysis of the oxt6 mutant, indicate that the polyadenylation factor AtCPSF30 is a regulatory hub where different signaling cues are transduced, presumably via differential mRNA 3' end formation or alternative polyadenylation, into specified phenotypic outcomes. Our results suggest a novel function of a polyadenylation factor in environmental and developmental signal integration.

Abstract
This study aimed to investigate the value of magnetic resonance spectroscopy (MRS) imaging in assessing nasopharyngeal carcinoma radiotherapy during the early delayed reaction period. Eighty cases of nasopharyngeal cancer treated with radiotherapy within the same period underwent MRS imaging before or after radiotherapy. Of the 80 cases, 47 underwent MRS imaging on the 3rd, 4th, 6th, and 12th months after radiotherapy. The trends of the primary metabolite concentration at different time points were monitored and compared with the corresponding data after radiotherapy. Repeated measures analysis of variance was performed. At the end of radiotherapy, the N-acetyl aspartate (NAA)/creatine (Cr), choline (Cho)/Cr, and NAA/Cho ratios were reduced to the lowest levels after 3 months. However, increasing trends were observed from the 4th to the 12th month. On the 12th month, stable levels were reached with statistically significant differences (F = 316.02, 53.84, 286.68; P < 0.01). MRS reflected the radiation injury-repair process in the brain of a nasopharyngeal cancer patient during early delayed reaction. This non-invasive monitoring of changes in brain tissue metabolite concentrations provides valuable information for prognosis.

Abstract
The objective of the present study was to examine the antitumor efficacy of the ethanol extract from Artemisia dracunculus as well as the compounds isolated from it on cultured EC‑109 esophageal squamous cell carcinoma (ESCC) cells. Apoptotic activities of the compounds were also studied using flow cytometry. EC‑109 esophageal cancer cells were treated with varying concentrations of compounds 1-7 isolated from the plant as well as the ethanol extract of Artemisia dracunculus. The cytotoxicity was evaluated by MTT assay and the apoptotic studies of the compounds were determined using flow-cytometry. Effect on mitochondrial membrane potential loss ΛΨ m induced by compounds 2 and 4 was also studied in these cells. Bioassay-guided fractionation of the ethanol extract from the shoot and root parts of Artemisia dracunculus led to the isolation of 7-methoxycoumarin (1), scopoletin (2), dracumerin (3), sakuranetin (4), elimicin (5), davidigenin (6) and 6-methoxycapillarisin (7). All the compounds as well as the extract showed mild to potent cell proliferation inhibitory activities against the esophageal cell line. Sakuranetin and 6-methoxycapillarisin were found to have the most potent effects in inhibiting the cell proliferation. The 2 potent compounds, sakuranetin and 6-methoxycapillarisin were evaluated for their effects on cell cycle phase distribution (DNA damage) as well as their effects on mitochondrial membrane potential loss ΛΨ m. Both compounds induced DNA damage as well as mitochondrial membrane potential loss in esophageal cancer cells. The study suggests that compounds, Sakuranetin and 6-methoxycapillarisin isolated from Artemisia dracunculus possess potent anticancer effects by inducing DNA damage in these cells.

Abstract
AIMS Biliary tract obstruction is a common clinical lesion. However, the effect of biliary tract obstruction on intestinal secretion is poorly understood. In this study, we made an investigation on intestinal HCO3 (-) and Cl(-) secretions in an experimental model of murine biliary duct ligation. METHODS Murine intestinal mucosal HCO3 (-) and Cl(-) secretions were examined in vitro in Ussing chambers by pH-stat and short-circuit current (Isc ) techniques. The mRNA and protein expressions of the cystic fibrosis transmembrane conductance regulator (CFTR) and the Na(+) -K(+) -2Cl(-) cotransporter (NKCC1) were analysed by real-time PCR, western blot and immunohistochemistry. RESULTS Basal Cl(-) secretion and forskolin-stimulated duodenal and jejunal mucosal HCO3 (-) and Cl(-) secretions in mice with common biliary duct ligation were markedly elevated, compared with controls (P < 0.05 and P < 0.01). Further experiments showed that basal Cl(-) secretion and forskolin-stimulated duodenal and jejunal mucosal HCO3 (-) and Cl(-) secretions in mice with external bile drainage were also markedly elevated. CFTRinh -172 inhibited forskolin-stimulated HCO3 (-) and Cl(-) secretions. The mRNA and protein expression levels of CFTR and NKCC1 in the intestinal mucosa with both biliary duct ligation and external bile drainage were markedly higher than those in controls (P < 0.001). Bile acid administration restored the changes in function and expression of CFTR and NKCC1 in the intestinal mucosa. CONCLUSION Bile deficiency in the intestine up-regulates the expressions of intestinal mucosal CFTR and NKCC1 and enhances intestinal mucosal HCO3 (-) and Cl(-) secretion capacity, which contributes to the understanding of intestinal physiological function for patients with biliary duct obstruction.

Abstract
The objective of this study was to explore the feasibility and methods of screening the residual normal ovarian tissue adjacent to orthotopic ovarian carcinomas in nude mice. Human epithelial ovarian cancer cells (OVCAR3) were subcutaneously implanted for a tumor source and ovarian orthotopic transplantation. The cancer tissue, proximal paraneoplastic tissue, middle paraneoplastic tissue, remote paraneoplastic tissue, and normal ovarian tissue were removed. CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was detected by reverse transcription polymerase chain reaction. We obtained 35 paraneoplastic residual ovarian tissues with normal biopsies from 40 cases of an orthotopic epithelial ovarian carcinoma model (87.5%). CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was lower in proximal paraneoplastic tissue than in cancer tissue (P < 0.05) and higher than in middle and remote paraneoplastic tissue (P < 0.01). There was no statistically significant difference between the expression of these genes in middle and proximal paraneoplastic tissue as well as among residual normal ovarian tissues with different severity (P > 0.05). In ovarian tissues of 20 normal nude mice, the expression of CK- 7, CA125, p53, survivin, MMP-2, and TIMP-2 was negative. Overall, the expression levels of CK-7, CA125, p53, survivin, MMP-2, TIMP-2, and other molecular markers showed a decreasing trend in the non-cancer tissue direction. The expression levels can be used as standards to screen residual normal ovarian tissue. We can obtain relatively safe normal ovarian tissues adjacent to epithelial ovarian cancer.

Abstract
OBJECTIVES To investigate the effect of multimodality treatment of advanced paediatric hepatoblastoma and the factors affecting the prognosis. PATIENTS AND METHODS 35 childhood patients were treated with multimodality treatments consisting of chemotherapy, surgery, interventional therapy, and autologous peripheral blood stem cell transplantation. Patients were followed up every month. RESULTS 33 patients completed the follow-up, of which 17 were in complete remission, 5 were in partial remission, 1 case got worse, and 10 died. The remission rate was 66.7% (22/33), and the overall survival rate was 69.7% (23/33). 1 patient with advanced hepatoblastoma got high-dose chemotherapy combined with autologous peripheral blood stem cell transplantation (APBSCT) treatment, and a primary lesion by 18 x 15 x 9 cm reduced to 10 x 8 x 4 cm. Remote metastases significantly alleviated, and partial remission reached six months. The overall survival was 9 months after transplantation. Patients with the mixed phenotype of hepatoblastoma had a worse prognosis than with the epithelial phenotype (p < 0.001), and patients in stage IV had a lower survival rate than in stage III (p < 0.001). CONCLUSIONS Multimodality treatment can effectively improve remission rate and prolong the survival of children with the advanced hepatoblastoma. In addition, alpha-fetoprotein (AFP), hepatoblastoma pathological classification and staging are of great use in prediction of prognosis.
