| 1 | Indocyanine green clearance test and model for end-stage liver disease score of patients with liver cirrhosis显示文摘BACKGROUND:The indocyanine green(ICG)clearance test(clearance rate(K)and retention rate at 15 minutes (R15))is a sensitive indicator to evaluate liver function. The model for end-stage liver disease(MELD)score has emerged as a useful tool for estimating the mortality of patients awaiting liver transplantation and has recently been validated on patients with liver diseases of various etiologies and severity.In this study,we investigated the correlation between the ICG clearance test and MELD score of patients with liver cirrhosis. METHODS:From June 2007 to March 2008,52 patients with liver cirrhosis admitted to our center were classified into Child-Pugh class A(8 patients),B(14)and C(30).The ICG clearance test(K value and R15)was performed by ICG pulse spectrophotometry(DDG-3300K),and the MELD scores of patients were calculated. RESULTS:As the Child-Pugh classification of liver function gradually deteriorated,the K value decreased, while R15 and MELD score increased.There were significant statistical differences in K value,R15 and MELD score in patients with different Child-Pugh classifications. Significant correlations were found between the parameters of the ICG clearance test(K value and R15)and MELD score.A negative correlation was observed between K value and MELD score(r=-0.892,P<0.05),while a positive correlation was observed between R15 and MELD score(r=0.804,P<0.05).CONCLUSIONS:The ICG clearance test and MELD score are good parameters for evaluating liver function.Moreover, K value and R15 have significant correlations with MELD score,especially the K value,which may be a convenient and appropriate indicator to evaluate liver function of patients with liver cirrhosis. | Sheng, Qin-Song Lang, Ren He, Qiang Yang, Yong-Jiu Zhao, De-Fang Chen, Da-Zhi | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，1： | 37 |

| 4 | Laparoscopic cystogastrostomy for the treatment of pancreatic pseudocysts: A case report显示文摘Pancreatic pseudocysts(PPs) are collections o pancreatic secretions that are lined by fibrous tissue and may contain necrotic debris or blood. The interventions including percutaneous, endoscopic o surgical approaches are based on the size, location symptoms and complications of a pseudocyst With the availability of advanced imaging system and cameras, better hemostatic equipments and excellent laparoscopic techniques, most pseudocyst can be found and managed by laparoscopy. We describe a case of a 30-year-old male patient with a pancreatic pseudocyst amenable to laparoscopi cystogastrostomy. An incision was made through the anterior gastric wall to expose the posterior gastri wall in close contact with the pseudocyst using an ultrasonically activated scalpel. Then, another incision was made for cystogastrostomy to obtain complete and unobstructed drainage. The patient recovered well after operation and was symptom-free during a 6-mo follow-up, suggesting that laparoscopi cystogastrostomy is a safe and effective alternative to open cystogastrostomy for minimally invasive management of PPs. | Qin-song Sheng Da-Zhi Chen Ren Lang Zhong-Kui Jin Dong-Dong Han Li-Xin Li Yong-Jiu Yang Ping Li Fei Pan Dong Zhang Zhao-Wei Qu Qiang He | 2008 | World Journal of Gastroenterology2008，14，30： | 15 |
| 5 | Ubi1 intron-mediated enhancement of the expression of Bt cry1Ah gene in transgenic maize (Zea mays L.)显示文摘The cry1Ah gene was one of novel insecticidal genes cloned from Bacillus thuringiensis isolate BT8. Two plant expression vectors containing cry1Ah gene were constructed. The first intron of maize ubiqutin1 gene was inserted between the maize Ubiquitin promoter and cry1Ah gene in one of the plant expressing vectors (pUUOAH). The two vectors were introduced into maize immature embryonic calli by microprojectile bombardment, and the reproductively plants were acquired. PCR and Southern blot analysis showed that foreign genes had been integrated into maize genome and inherited to the next generation stably. The ELISA assay to T1 and T2 generation plants showed that the expression of Cry1Ah protein in the construct containing the ubi1 intron (pUUOAH) was 20% higher than that of the intronless construct (pUOAH). Bioassay results showed that the transgenic maize harboring cry1Ah gene had high resistance to the Asian corn borers and the insecticidal activity of the transgenic maize containing the ubi1 intron was higher than that of the intronless construct. These results indicated that the maize ubi1 intron can enhance the expression of the Bt cry1Ah gene in transgenic maize | WANG YueBing LANG Zhihong ZHANG Jie HE KangLai SONG FuPing HUANG DaFang | 2008 | Chinese Science Bulletin2008，53，20： | 15 |

| 12 | Establishment of an animal model of ischemic type intrahepatic biliary lesion in rabbits显示文摘AIM:To explore a method to establish an animal model of ischemic type intrahepatic biliary lesion in rabbits. METHODS:Forty Japanese white rabbits of clean grade were divided randomly into four groups(10 rabbits per group)including sham operation(SO) group,and artery-bile obstruction(ABO)-1 h group, ABO-2 h group and ABO-3 h group.All the rabbits in this study underwent the same initial surgical procedure in which the liver was prepared as for graft removal during liver transplantation.Subsequently in the SO group,no additional vascular intervention was performed,while in groups ABO-1 h,ABO-2 h and ABO-3 h,the animals underwent combined clamping of the hepatic artery and common bile duct with microvascular clips for 1,2 and 3 h,respectively.After the scheduled occlusion time,the clip was removed to recover blood supply.The animals were killed 4 wk after operation.The survival rate,liver function, cholangiography and histopathological manifestation of the rabbits in each group were observed. RESULTS:The survival rate was 100%in groups SO,ABO-1 h and ABO-2 h,while it was 60%in group ABO-3 h.At each observation time,the change degree of the indexes of liver function was proportional to the clamping time(ABO-3 h>ABO-2 h>ABO-1 h> SO,P<0.05).Cholangiographical and histopathologic manifestations both showed that intrahepatic biliary lesion aggravated proportionally with the increase of the clamping time. CONCLUSION:An animal model of ischemic type intrahepatic biliary lesion in rabbits is successfully established,which may provide a reliable technique for basic and clinical research into the etiology, development and prophylaxis of ischemic type intrahepatic biliary lesion after liver transplantation. | Qin-song Sheng Da-Zhi Chen Ren Lang Qiang He Yong-Jiu Yang Zhao-Wei Qu De-Fang Zhao Xiao-Sheng Zhang | 2009 | World Journal of Gastroenterology2009，15，6： | 9 |
| 13 | Autoimmune pancreatitis:report of two cases and literature review显示文摘BACKGROUND:Autoimmune pancreatitis(AIP)is a unique chronic inflammation of the pancreas in which autoimmune mechanisms are involved in the pathogenesis.It is characterized by clinical,histopathological,radiographic,serologic and therapeutic features.Since it was first described in 1995,increasing numbers of AIP patients have been diagnosed.METHODS:In this study,the data from 2 patients with AIP who had elevation of serum immunoglobulin G,positive autoantibody,swelling of the pancreas and narrowing of the main pancreatic duct on imaging were analyzed retrospectively.RESULTS:With the initial diagnosis of AIP,both patients underwent regular prednisone therapy,which was initiated at a dose of 40 mg per day with a tapering schedule of 5 mg every 2 weeks.The patients responded very well to treatment with prednisone.CONCLUSIONS:AIP is a relatively new disease entity.Although it is diagnosed by distinct characteristics of the clinical,radiologic,histopathologic,and serologic findings,many questions require further clarification,including its relationship to other autoimmune diseases and misdiagnosis as pancreaticobiliary malignancies. | Sheng, Qin-Song Chen, Da-Zhi Lang, Ren He, Qiang Han, Dong-Dong Pan, Fei Li, Ping Qu, Zhao-Wei | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，6： | 8 |
