Objective:To study the clinical effect and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of liver cirrhosis with esophageal variceal bleeding.Methods:86 cases of cirrhotic patients with esophageal and gastric varices bleeding admitted in our hospital from August 2013 to April 2015 were selected and randomly divided into the control group and the observation group with 43 cases in each group.The control group underwent percutaneous transhepatic coronary vein embolization (PTVE) treatment,while the observation group were treated with TIPS.The success rate of surgery,the incidence of various complications,the long-term survival rate and the symptoms and the changes of liver function after operation were compared between the two groups of patients.Results:The portal vein pressure after operation in the observation group was significantly lower than that of the control group (P=0.00),at 3 months,6 months and 12 months after operation,the rebleeding rate in the observation group were significantly lower than that of the control group (P＜0.05),but the incidence of hepatic encephalopathy showed no significant difference between the two groups (P＞0.05);before operation and at 6 months and 12 months after operation,the Child-Pugh score,serum TBIL,DBIL levels showed no significant difference between the two groups (P＞0.05),at 3 months after operation,the Child-Pugh score,serum TBIL,DBIL levels in the observation group were significantly higher than those of the control group (P＜0.01);the 1 year survival rate showed no significant difference between two groups (P=0.72).Conclusion:TIPS could effectively improve the symptoms of varicose veins,better on liver function damage,and enhance the long-term survival high rate with high safely in the treatment of esophageal variceal bleeding in patients with cirrhosis.

According to their polypeptide length and number of d is ulphide bonds, disintegrins are divided into five groups, including short-sized disintegrins, medium-sized disintegrins, long-sized disintegrins, dimeric dis integrins and disintegrin-like molecules released from the disintegrin-like do mains of P-III snake venom metalloproteinases. The integrin-inhibitory activit y of disintegrins, to inhibit platelet aggregating, cell attaching and angiogene sis, depends on the active tripeptide RGD, the appropriate pairing of cysteine r esidues, the amino acids adjacent to the RGD motif within the integrin-binding loop and the C-terminus of the disintegrin polypeptidesl as well.

ObjectiveTo investigate the inhibitory effect of polysaccharides from Sargassum fusiforme on the HepG 2 cells. Methods Six kinds of polysaccharides were prepared by hot water extracting, ethanol and CaCl 2 precipitating and acid hydrolyzing. Inhibition rate of these polysaccharides on the HepG 2 cells were determined by MTT bioassay. Results Inhibition rate of two kinds of polysaccharides increased at lower concentration. Inhibition ratie of other polysaccharides increased with the increment of concentration. At the dose less than 2000mg?L -1,inhibition rate was not more than 40%. Conclusion All polysaccharide specimens obtained from Sargassum fusiforme have some inhibitory effects on human liver cancer cells HepG 2.

5 000 mg/L). ② All extracts except algin (ALG) had an obviously HSV-1 inhibitory effect. Antiviral activities of them were increasingly strengthened with their purities. Antiviral activities of extracts from flucoidan 1, F 1, F 2 and F 4 were better than acyclovir (ACV). ③ Antiviral activities of all extracts on CVB 3 were better than ribavirin injection. F 1, F 2 and F 4 had remarkable anti-CVB 3 effects. ④ The experiment showed that Sargassum fusiforme polysaccharides not only kill the above viruses directly but also restrain them via getting into cells or absorbing on cells.

Objective: To analyze the correlations between intraoperative ultrasound and MRI metrics of the spinal cord in degenerative cervical myelopathy and identify novel potential predictive ultrasonic indicators of neurological recovery for degenerative cervical myelopathy. Materials and Methods: Twenty-two patients who underwent French-door laminoplasty for multilevel degenerative cervical myelopathy were followed up for 12 months. The Japanese Orthopedic Association (JOA) scores were assessed preoperatively and 12 months postoperatively. Maximum spinal cord compression and compression rates were measured and calculated using both intraoperative ultrasound imaging and preoperative T2-weight (T2W) MRI. Signal change rates of the spinal cord on preoperative T2W MRI and gray value ratios of dorsal and ventral spinal cord hyperechogenicity on intraoperative ultrasound imaging were measured and calculated. Correlations between intraoperative ultrasound metrics, MRI metrics, and the recovery rate JOA scores were analyzed using Spearman correlation analysis. Results: The postoperative JOA scores improved significantly, with a mean recovery rate of 65.0 ± 20.3% (p < 0.001). No significant correlations were found between the operative ultrasound metrics and MRI metrics. The gray value ratios of the spinal cord hyperechogenicity was negatively correlated with the recovery rate of JOA scores (ρ = -0.638, p = 0.001), while the ventral and dorsal gray value ratios of spinal cord hyperechogenicity were negatively correlated with the recovery rate of JOA-motor scores (ρ = -0.582, p = 0.004) and JOA-sensory scores (ρ = -0.452, p = 0.035), respectively. The dorsal gray value ratio was significantly higher than the ventral gray value ratio (p < 0.001), while the recovery rate of JOA-motor scores was better than that of JOA-sensory scores at 12 months post-surgery (p = 0.028). Conclusion For degenerative cervical myelopathy, the correlations between intraoperative ultrasound and preoperative T2W MRI metrics were not significant. Gray value ratios of the spinal cord hyperechogenicity and dorsal and ventral spinal cord hyperechogenicity were significantly correlated with neurological recovery at 12 months postoperatively.
