Objective To evaluate the diagnostic value of intraductal ulstrasonography(IDUS)in non-opaque bile duct stones.Methods Between January 2009 and August 2010 in the Department of Gastroenterology at Shanghai 10th People's Hospital,a total of 183 patients(male:102 cases,mean age 69 years； female:81 cases,mean age 71 years)were enrolled,who were suspected of bile duct stones or stenosis which could not be diagnosed by abdominal CT,MRI,and abdominal B-mode ultrasound.All the patients underwent endoscopic retrograde cholangiopancreatography(ERCP)first,and then patients with non-opaque bile duct stones followed by IDUS.Results A total of 134 cases (73.2％)of bile duct stones were diagnosed by ERCP,49 cases(26.8％)were negative.And then the 49 patients underwent IDUS,of whom 24 patients with sand-like stones,11 patients with lowdensity stones,6 patients with ampullary cancer,2 patients with pancreatic cancer,6 patients with sclerosing cholangitis.The diagnostic accuracy of IDUS in the position and quality of bile duct stones was 100％,higher than that of ERCP,which was 80％.After ERCP,pancreatitis occurred in 3 patients and improved after conservative treatment,there was no complications like perforation and bleeding.Conclusion The diagnostic accuracy of IDUS in the position and quality of bile duct stones is high,which can make up for the misdiagnosis by ERCP without increasing the complications.IDUS can provide reliable basis for the diagnosis of clinical bile duct stones.

Objective:To investigate the expression of MKK 4 protein in the nasopharyngeal carcinoma and its clinical significance.Methods:Immunohistochemical methods were employed to analyze MKK 4 positive expression intensity and positive cells in freshly collected nasopharyngeal carcinoma of both 90nasopharyngeal carcinoma cases and 20 chronic nasopharyngitis control.The clinical pathological characteristic were analyzed.Results:The data obtained by MKK4 immunohistochemistry showed that the MKK 4 positive rate was higher in control group than in the NPC group (95.5%vs 75.6%,P<0.05).The expression of MKK4 was related to tumor differentiation and lymph node metastasis ( P<0.05 ) , but not to gender , age, tumor volum and TNM stage ( P>0.05 ) . Conclusion:Positive rate of MKK4 protein in nasopharyngeal carcinoma tissues is lower than in chronic nasopharyngitis.MKK4 protein expressions in nasopharyngeal carcinoma tissues negatively correlated with lymph node metastasis ,clincal stage ,invasive depth ,and TTP (Time to progression),but not with age,gender,location and tumor volume.

OBJECTIVE: To investigate the association between-1304T/G polymorphism in the promoter of MKK4 gene and the susceptibility in sporadic nasopharyngeal carcinoma. METHOD: MKK4-1304T/G genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 90 NPC cases and 30 healthy controls. RESULT: The number of nasopharyngeal carcinoma patients carrying with TG+GG genotype was much higher than those of controls (82.2% vs 66.7%, χ² =10.076, P < 0.05). Analysis showed that compared with the-1304TT genotype, -1304TG heterozygous reduced risk of nasopharyngeal carcinoma 0.56 fold (95% CI = 0.164-1.178, P < 0.01) and-1304GG lower 0.58 fold (95% CI = 0.126-1.381, P < 0.01), TG+ GG genotype variation risk of nasopharyngeal carcinoma decreased 0.72 fold (95% CI = 0.105-0.753, P < 0.01). CONCLUSION MKK4 gene-1304TG genotype can reduce risk of nasopharyngeal carcinoma, and it may be an independent protection factor in sporadic nasopharyngeal carcinoma.

OBJECTIVETo study the effects of Yupingfeng Powder (YPFP) on cisplatin (DDP) induced oxidative damage of organs in hepatocellular carcinoma mice.

METHODSA total of 2 x10(6) Hepa1 -6 cells were inoculated subcutaneously into the right flank of 15 C57BL/6 mice to establish a mice model of hepatocellular carcinoma. Then the mice were randomly divided into three groups, i.e., the model group, the DDP group, and the DDP + YPFP group, 5 in each group. Mice in the DDP group and the DDP + YPFP group were intraperitoneally injected with DDP (2. 5 mg/kg), once every three day for 2 weeks. Physiological saline was intraperitoneally injected to mice in the model group. Meanwhile, YPFP water decoction (25 g/kg) was given to mice in the DDP + YPFP group by gastrogavage once daily for 2 weeks. Corresponding distilled water was given by gastrogavage to mice in the DDP group and the model group. Fourteen days later, mice were sacrificed and the tumor inhibition ratio was calculated. The weights of kidneys, livers, and lungs were weighed and the organ coefficient calculated. The activities of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in the tissue were detected. The pathologic changes were observed.

RESULTSThe tumor weight obviously decreased in the DDP group and the DDP + YPFP group when compared with the model group (P < 0.05, P < 0.01). Obvious oxidative damage existed in the kidneys and livers after induced by DDP. Oxidative damage also existed in the lungs to some extent. YPFP could obviously decrease the content of MDA and the activities of SOD in livers (P < 0.05), and increase the activities of SOD in lungs (P < 0.01). The pathologic changes showed the same effect trend.

CONCLUSIONSYPFP could protect the organs (kidney, liver, lung) from the oxidative damage induced by DDP. Anti-oxidation is one of its mechanisms.
