ObjectiveTo determine the clinical effect and the prospect of cervical side-to-side stapled esophagogastric anastomosis. MethodsEighteen cases of upper and middle thoracic esophageal carcinoma were treated with esophagectomy and cervical side-to-side stapled esophagogastric anastomosis. The clinical data were collected and retrospectively analyzed. The average age of patients was 60.7 years and the ratio of male to female was 17∶1. The tumor included 4 upper part and 14 middle thoracic parts. The length of tumors was from 1 cm to 7 cm, with an average of 3.2 cm.ResultsThe post-operative TNM staging(AJCC) included 4 Stage Ⅱa,9 Stage Ⅱb,and 5 Stage Ⅲ. The operative incisions included 8 nontransthoracic cervical and abdominal double incisions, 9 right cervico-thoraco-abdominal triple incisions, and 1 left cervico-thoracic incision. One (5.56%) patient complicated with anastomotic leakage and was cured in 2 weeks by cervical drainage and absolute diet. All the 18 patients were followed up for 1 to 5 years,and no anastomotic stricture was found. Reflux esophagitis was found in 2 and the incidence rate was 11.11%.ConclusionCervical side-to-side esophagogastric anastomosis is a safe procedure with larger resection of margins and fewer complications. It is worth replicating.

AIM: To evaluate the effect of endothelial myosin light chain kinase on extravasation migration of sarcoma cell. METHODS: An in vitro model of sarcoma cell transmigration across a monolayer of HUVEC cultured on collagen gel was used to observe extravasation migration of sarcoma cell and calculated the electrical resistance of HUVEC monolayer in extravasation migration of sarcoma cell. RESULTS: Sarcoma cell migrated through a gap between adjacent endothelial cells into collagen gel. The electrical resistance of a HUVEC monolayer reduced in extravasation migration of sarcoma cell.Endothelial myosin light chain kinase inhibitor(ML-7) inhibited extravasation migration of sarcoma cell and inhibited reduction of electrical resistance of a HUVEC monolayer in extravasation migration of sarcoma cell in a dose-dependent manner. CONCLUSION: Endothelial myosin light chain kinase regulates sarcoma cell transendothelial migration by phosphorylation of myosin light chain.

Objective To evaluate the effect of hepatocyte growth factor(HGF) on transvascular metastasis of sarcoma cells.Methods The models of intravascular and extravascular migration of tumor cells in vitro were used to observe transvascular metastasis of sarcoma cells(HT1080).Results HT1080 migrated through basement membrane into blood vessels,and migrated through a gap between adjacent endothelial cells into extracellular matrix.The greater number of transmigrated HT1080 treated with HGF was observed(P

AIM: To evaluate the effect of tissue factor on intravascular migration of tumor cells.METHODS: Expression of tissue factor in tumor cells (HT1080) was analyzed by flow cytometry and immunofluorescence staining. An in vitro model was used to observe intravascular migration of tumor cells. RESULTS: High expression of tissue factor was observed in tumor cells (HT1080). The antibody for tissue factor inhibited intravascular migration of tumor cells. CONCLUSION: Tissue factor stimulated tumor metastasis through promoting intravascular migration of tumor cells.

Objective:To compare the models of guinea pig allergic rhinitis induced by different allergens. Methods: Ovalbumin (OVA), 2,4-tolylene diisocyanate (TDI) and alternariaalternata was respectively used as the allergens to establish the model of guinea pigs allergic rhinitis. The conformity of the models and human allergic rhinitis was studied through the behavioral indices, such as the times of nose itches, nasal discharge flow, histological properties and serum HA and IgE indices. Results:The times of sneezing and scratching nose, serum HA and IgE in OVA group was significantly different from those in the control group (P<0. 001 or P<0. 01). Conclusion:The models of allergic rhinitis induced by OVA are the same as allergic rhinitis in typical symptoms and pathological changes.

0.05). Phagocytic index of RPE cells was (28.7?1.9)% in the presence of 10 ?mol?L~ -1 DIDS,10 ?mol?L~ -1 DIDS significantly inhibited the nonspecific phagocytic process of human RPE cells(P

AIM: To evaluate the effect of endothelial Rho and Rho kinase in extravasation migration of sarcoma cell. METHODS: We used an in vitro model of sarcoma cell transmigration across a monolayer of HUVEC cultured on collagen gel to observe extravasation migration of sarcoma cells and calculated the electrical resistance of HUVEC monolayer in extravasation migration of sarcoma cells. RESULTS: Sarcoma cells migrated through endothelial cells into collagen gel, the electrical resistance of a HUVEC monolayer reduced in extravasation migration of sarcoma cells.Endothelial Rho inhibitor(C3 transferase) and Rho kinase inhibitor(Y-27632) inhibited extravasation migration of sarcoma cells and inhibited reduction of electrical resistance of a HUVEC monolayer in extravasation migration of sarcoma cells. CONCLUSION: Endothelial Rho and Rho kinase regulates sarcoma cell transendothelial migration through modification of endothelial cytoskeleton.

The change of kirenol, darutigenol and darutoside in Siegesbeckia and its first to ninth processed products were studied, and the ten fingerprints were compared, which provided the experimental basis for the study of Siegesbeckia processing tech- nology. The samples were analysed by HPLC on a SunFire-C18 column (4.6 mm x 150 mm, 5 μm) with gradient elution of acetonitrile (0.1% formic acid)-water (0.1% formic acid) at a flow rate of 1.0 mL x min(-1). Column temperaturewas 30 °C and the detected wavelength was 215, 320 nm. The calibration curves of kirenol, darutigenol and darutoside were linear in the range of 2.180-26.16, 2.900-34.80, and 1.012-6.072 mg x L(-1), respectively, and the average recoveries were 96.4%, 97.2% and 96.3% wit RSD 2.2%, 1.7% and 2.4%. This method was simple, the result was stable and had good repeatability, recovery and precision. The re- sult was the basis of the chemical contents variation in the processing of Siegesbeckia Herbs and further clarifying the effect of the changing.

This study was aimed to optimize the purification technology for Sambucus williamsii Hance. With the morroniside as a marker, the purification technology for Sambucus williamsii Hance was optimized by different types of macroporous resin. The results showed that the optimum purification technology was that, the extract of less than 1:250 (morroniside:resin) was adsorbed and the AB-8 resin was washed with distilled water, and then the morroni-side was eluted from the macroporous resin with 10% ethanol. And the content of the morroniside was more than 50%. It was concluded that the purification technology was simple, reliable, repeatable and suitable for industrial production.
