BACKGROUND Despite being a benign disease, hepatolithiasis has a poor prognosis because of its intractable nature and frequent recurrence. Nonsurgical treatment is associated with high incidences of residual and recurrent stones. Consequently, surgery via hepatic lobectomy or segmental hepatectomy has become the main treatment modality. Clinical management and resolution of complicated hepatolithiasis with bilateral or diffuse intrahepatic stones remain very difficult and challenging. Repeated cholangitis and calculous obstruction may result in secondary biliary cirrhosis, a limiting factor in the treatment of *** SUMMARY A 53-year-old woman with a 5-year history of intermittent abdominal pain and fever was admitted to the hepatopancreatobiliary surgery department following worsening symptoms over a 3-d period. Blood tests revealed elevated transaminases, alkaline phosphatase, γ-glutamyl transpeptidase, and total bilirubin, as well as anemia. Magnetic resonance cholangiopancreatography showed dilatation of the intrahepatic, left and right hepatic, common hepatic, and common bile ducts, and multiple short T2 signals in the intrahepatic and common bile ducts. Abdominal computed tomography showed splenomegaly and splenic varices. The diagnosis was bilateral hepatolithiasis and choledocholithiasis with cholangitis. Surgical treatment included hepatectomy of segments Ⅱ and Ⅲ, cholangioplasty, left hepaticolithotomy, second biliary duct exploration, choledocholithotomy, T-tube drainage, and accretion lysis. Surgical and pathological findings confirmed secondary biliary cirrhosis. Liver-protective therapy and anti-infectives were administered. The patient developed liver and respiratory failure, severe abdominal infection, and septicemia. Eventually, her family elected to discontinue *** Liver transplantation, rather than hepatectomy, might be a treatment option for complicated bilateral hepatolithiasis with secondary liver cirrhosis.

AIM To assess the effects of hepatitis B virus(HBV) on the expression of host α-1,2-mannosidases and determine the underlying *** We measured the expression levels of MAN1A1, MAN1A2, MAN1B1, and MAN1C1 in cell lines HepG 2.2.15, HepN 10, HepA D38 and Hep G2 by Western blot. Viral antigens(HBs Ag and HBe Ag) in the culture medium were measured using the chemiluminescence method. HBV DNA quantification assays were performed using a commercial real-time PCR kit. Protein levels of human liver tissue α-1,2-mannosidases were also evaluated by Western blot. Plasmids containing seven individual viral genes of HBV(PTT22-HBx, PTT22-HBs, PTT22-pre S2, PTT22-pre S1, PTT22-HBc, PTT22-HBe, and PTT22-HBp) or control plasmids(PTT22-vector) were transfected into Hep G2 cells. MK886(PPARα) and GW9662(PPARγ) inhibitors were used to explore the effects of HBV on α-1,2-mannosidase expression after the PPARα and PPARγ pathways were *** We showed that the expression of α-1,2-mannosidases was higher in stably transfected HBV cells than in controls. The expression levels of α-1,2-mannosidase were higher in AD38 cells than those in ND10 cells, which were in turn greater than those in G2.2.15 cells, and positively correlated with the expression of HBsA gin all the cell lines. Levels of α-1,2-mannosidase in nontumorous liver tissues of HBV-related HCC patients were also higher than in the tissues from non-HBVrelated HCC patients. Moreover, transfecting Hep G2 cells with a component of the HBV viral envelope also increased the expression of α-1,2-mannosidases. However, this envelope protein component could not induce MAN1C1 expression in the presence of a PPARα inhibitor, MK886. We also found that MK886 did not affect the expression of MAN1C1 in AD38 cells without tetracycline in the culture medium. This phenomenon was not observed in the case of *** Our results indicate that HBV increases the expression of α-mannosidases both in vitro and in vivo via ac

Chinese Medical Journal 2013年第24期126卷 4665-4669页

作者： WU Min-jie WANG xiao-jing zou Li-dong XU Wei-hua ZHANG Xiang-hao Second Dental Center Peking University School and Hospital of Stomatology Beijing 100101 China

Background Dental implant technology has developed rapidly in recent years. However, the use of implant-supported fixed bridges with cantilevers has been controversial. The purpose of this study was to evaluate the clinical results of the mandibular anterior implant-supported fixed bridges with a cantilever. Method Thirty-three patients （15 males, 18 females; mean age, 42.6 years; range 20-54 years） with two missing anterior mandibular teeth had single implant-supported fixed bridges with a cantilever. Clinical examination was recorded and radiographs were taken. The mean duration of follow-up was 30 months （15-44 months）. Results All implants survived. Loosening or fracture of the prosthesis was not observed. All patients were satisfied with the treatment. The mean bone resorption values after 12, 24, and 36 months of implant loading were 0.94, 1.18 and 1.35 mm respectively. The changes of gingival papilla height ranged from 0 to 0.5 mm. There was significant difference between 1-year and 2 or 3 years restoration groups regarding the average gingival height changes （P 〈0.05）. Conclusion After careful and precise selection of patients, restoration with a single implant-supported fixed bridge with a cantilever can be recommended if two anterior mandibular teeth are missing.
