To investigate the influence of the difference enhancers on the transport mechanism of chlorogenic acid (CGA) across Caco-2 cells model, a RP-HPLC method was adopted to detect the concentrations of CGA. At the concentrations of 20 to 80 microg x mL(-1), the difference of absorption rate constants (K(a)) was not statistically significant. At the concentrations of 40 and 20 microg x mL(-1), the ratios of apparent permeability coefficients (P(app)) of the apical to basolateral and the basolateral to apical were 1.14 and 1.18, respectively. With the effect of enhancers K(a) and P(app) increased, the absorption half-life (T1/2) decreased. CGA passed through the Caco-2 cell membrane mainly by passive transport. It showed that monocarboxylic acid transporter (MCT) could be involved in the across membrane transport process of CGA. Borneol had no effect on the cell membrane transport processes. The order of increasing absorption of CGA caused by the enhancers was sodium lauryl sulphate > sodium taurocholate > carbomer.

Aim To investigate the effect of acacetin on cell proliferation and the influence of acacetin on estrogen receptor expression in vitro.Methods The proliferation rates and the cell cycle changes of acace-tin-treated T47D cells were measured by sulforhodam-ine B(SRB)assay and flow cytometry,respectively. Moreover,the mRNA expressions of estrogen receptor-alpha(ERα),estrogen receptor-beta(ERβ)and pro-liferating antigen(Ki67)were determined by quantita-tive real time PCR (qPCR).Western blot was em-ployed to detect the ERαand ERβprotein expression. Results Acacetin significantly promoted the prolifera-tion and increased the amount of cells arrested in S and G2 /M phase under the concentration of 0.001 ~1 0μmol·L -1 .Ki67 mRNA level and the ERαprotein level in T47D cells were remarkably upregulated after acacetin treatment.To clarify which estrogen receptors played a role in acacetin induced the proliferation of T47D cells,the combination treatment of acacetin and ERαinhibitor (MPP)/ERβ inhibitor (PHTPP) was employed.We found that MPP could reverse the cell proliferation,the cell arrested in S and G2 /M phase and the increased Ki67 mRNA level induced by acace-tin.PHTPP also alleviated the T47D cell proliferation induced by acacetin,whereas no significant changes were found in cell cycle and Ki67 mRNA level.Con-clusion Acacetin stimulates the cell proliferation of T47D cells in the concentration from 0.001 μmol · L -1 to 1 0 μmol·L -1 ,which is mainly mediated by ERα.

Objective To explore the impact of pancreatobiliary reflux (PBR) in normal pancreatobiliary junction on gallbladder.Methods A total of 54 patients receiving cholecystectomy for gallbladder diseases underwent ultrasonography to evaluate the thickness of gallbladder wall,inner layer and gallbladder wall blood flow before operation.The bile juice was sampled during ERCP in 45 patients with common bile duct stone and during cholecystectomy in 9 patients to detect amylase level.All patients with normal pancreatobiliary junction enrolled in the study were assigned into PBR group (n =24) and controlled group (n =30) according to their bile amylase level.Resected gallbladder specimens were examined histopathologically and then tested for expression of COX2,Ki-67 and p53 immunohistochemically.Results PBR group included 20 cases of cholelithiasis and 4 gallbladder polyp,among which 23 were occult PBR (OPBR) and 1 high confluence of pancreatobiliary ducts (HCPBD),which was similar to pancreatobiliary maljunction (PBM) pathologically.The control group recruited 28 cases of cholelithiasis and 2 gallbladder polyp.There were no differences in frequency of inflammation,hyperplasia,metaplasia or expression of p53 between the two groups (p > 0.05),while higher presence of dysplasia and higher expression of COX2 and Ki-67 were seen in PBR group (p < 0.05).Conclusion In patients with OPBR,although hyperplasia and metaplasia in gallbladder epithelium were similar to those induced by cholelithiasis,dysplasia and active proliferation might relate to progress to malignancy.

METHODS Between February 2013 to May 2014, 16 patients with mAVMs received embolotherapy in our department. Eight cases' mAVMs located in mandibular region, 5 cases located in the maxillary region and the other 3 cases located near the orbital region. Embolotherapy with Onyx was carried out in all patients and all the patients were followed-up. The effect of embolization was evaluated according to the deformity arteriolar blood flow. RESULTS After the embolization, angiograpy showed that complete occlusion of mAVMs was achieved in 3 cases, 50%-90%occlusion in 10 cases, <50% occlusion in 3 cases, and the overall response rate was 81.25% (13/16). After operation, temporary decreased vision was obtained in one patient and recovered after 20 days, no permanent visual abnormality was found in all of the cases. Complications as distending pain, fever disappeared in 13 patients, improved in 2 patients and became worse in one patient. There was no case of skin necrosis occurred. Follow-up for 6 months after treatment, the deformity arteriolar blood flow larger than before was found in 2 cases and the others were stable. CONCLUSION Onyx embolization for the treatment of maxillofacial arteriovenous malformation is a safe and effective method, the short term curative effect has been confirmed while the long term curative effect should be further evaluated.

Objective To investigate the clinical effect of endovascular embolization in treating spinal dural arteriovenous fistulae, and to discuss its imaging manifestations. Methods A total of 7 patients with spinal dural arteriovenous fistulae were included in this study. Endovascular embolization was carried out in all the 7 patients. The clinical data, including epidemiology, spinal MRI and DSA manifestations, therapeutic method and follow-up findings, were retrospectively analyzed. Results Abnormal MRI manifestations of spinal cord were demonstrated in all 7 patients. After the diagnosis was confirmed by DSA, endovascular embolization was carried out. All patients were followed up for 6 months, and their clinical symptoms were improved in different degrees. N-butyl cyanoacrylate (NBCA) glue was used as embolization agent in 4 cases, and no recurrence was observed in them. Onyx liquid glue was used in 3 patients, and in one of them the arteriovenous fistula recurred. Conclusion For the treatment of spinal dural arteriovenous fistulae, endovascular embolization is effective and safe although further investigation is still needed.
