OBJECTIVETo develop a simple method for genotyping of hepatitis E virus (HEV) and to investigate HEV genotype distribution in Nanjing area.

METHODSTwenty-seven full HEV sequences currently-available in GenBank were analyzed with MegAlign and MapDraw programs of DNA STAR software. Degenerate primers were designed and applied to amplify a fragment in HEV ORF1 region. HEV genotypes were determined by the size of the PCR products and by single restriction endonuclease analysis.

RESULTSThe PCR products of HEV genotype 1 and 2 were 275 bp and 269 bp in size. Distinctively, the PCR products of genotype 3 and 4 were 317 bp and 314 bp in size. Moreover, the PCR products of genotype 1 could be digested by Nae 1, but the products of genotype 2 could not. Distinctively, the PCR products of HEV genotype 3 could be digested by Not 1, but the products of genotype 4 could not. Six HEV reference strains standing for different HEV genotypes were clustered into their own types as predicted. Within 43 HEV IgM-positive clinical specimens collected in Nanjing, 19 were HEV PCR-positive and identified as genotype 4.

CONCLUSIONA simple method of PCR combined with single restriction endonuclease analysis is developed for HEV genotyping. This assay allows rapid identification of a large number of HEV isolates directly from clinical specimens. Among patients with hepatitis E in Nanjing, most were infected with HEV genotype 4.

OBJECTIVETo compare the clinical efficiency of two strategy in the treatment of secondary common bile duct stones: laparoscopic cholecystectomy with transcytotic common bile duct exploration (LC + LTCBDE), or laparoscopic cholecystectomy after endoscopic sphincterotomy (EST + LC).

METHODSAccording to the screening standard, 88 patients with secondary bile duct stones (43 cases in LC + LTCBDE group, 45 cases in EST + LC group) who were treated from June 2005 to November 2007 were analyzed retrospectively. The achievement ratio, complications, average hospital stay and cost between two groups were compared. And all patients were followed up.

RESULTSThere were no significant differences on achievement ratio and complications between two groups (P > 0.05). The LC + LTCBDE group has significantly shorter hospital stay and lower cost (P < 0.05). There were no recurrence in 1 year.

CONCLUSIONSLTCBDE is a promising strategy which has more advantages in the minimal invasive treatment of secondary common bile duct stones.

OBJECTIVETo investigate the association of heptitis B virus (HBV) genotypes and precore(PreC)/basal core promoter(BCP) mutation with interruption failure of HBV vaccination in mother-to-infant transmission.

METHODSA total number of 208 serum samples were collected from infants and mothers,including 16 infants who had become HBsAg-positive despite a complete and timely course of immunization and another 88 infants successfully protected from mother-to infant HBV transmission. HBV genotypes were determined by type-specific primers PCR method. PreC/BCP mutations were detected by direct sequencing of PCR products, and Clustal W 1.8 software was applied to analyzing the sequences.

RESULTSOf 16 mothers who were having vaccine failure infants, 15 (93.8%) were HBeAg positive and infected with genotype C (15/15, 100%). Among 88 mothers of having children being protected by vaccine, 51 (58.0%) were HBeAg positive, with 45.1% (23/51) of genotype C. The proportion of genotype C in HBeAg mothers of infants with vaccine failure, was significantly higher than that of mothers with vaccine protected infants (chi2 = 14.3, P = 0.003). However, the frequencies of T1762/A1764 mutations had no significant differences between genotype C HBeAg positive mothers with vaccine failure or protected infants (33.3% and 13.3%, respectively, P = 0.4). No A1896 mutation was found in these two groups.

CONCLUSIONHBV genotype C might contribute to the immune failure of HBV vaccination in mother-to-infant transmission, while PreC/BCP mutation might not have correlation with it.

BACKGROUNDWe undertook a randomized controlled trial to ascertain if single-incision laparoscopic cholecystectomy (SILC) was more beneficial for reducing postoperative pain than traditional laparoscopic cholecystectomy (TLC). Moreover, the influencing factors of SILC were analyzed.

METHODSA total of 552 patients with symptomatic gallstones or polyps were allocated randomly to undergo SILC (n = 138) or TLC (n = 414). Data on postoperative pain score, operative time, complications, procedure conversion, and hospital costs were collected. After a 6-month follow-up, all data were analyzed using the intention-to-treat principle.

RESULTSAmong SILC group, 4 (2.9%) cases required conversion to TLC. Mean operative time of SILC was significantly longer than that of TLC (58.97 ± 21.56 vs. 43.38 ± 19.02 min, P < 0.001). The two groups showed no significant differences in analgesic dose, duration of hospital stay, or cost. Median pain scores were similar between the two groups 7 days after surgery, but SILC-treated patients had a significantly lower median pain score 6 h after surgery (10-point scale: 3 [2, 4] vs. 4 [3, 5], P = 0.009). Importantly, subgroup analyses of operative time for SILC showed that a longer operative time was associated with greater prevalence of pain score >5 (≥100 min: 5/7 patients vs. <40 min, 3/16 patients, P = 0.015).

CONCLUSIONSThe primary benefit of SILC appears to be slightly less pain immediately after surgery. Surgeon training seems to be important because the shorter operative time for SILC may elicit less pain immediately after surgery.

OBJECTIVETo investigate the clinical characteristics and diagnosis of mucopolysaccharidosis VII.

METHODThe clinical and biochemical features of an infant with mucopolysaccharidosis VII confirmed by enzyme assay were analyzed.

RESULTThe 2 month-old male infant showed hydrops fetalis, mental retardation, coarse face, corneal clouding, hepatosplenomegaly, hernias, Alder-Reilly granules in the leucocytes and decreased platelet (32 × 10(9)/L). The biochemical markers showed urinary glycosaminoglycans (GAG) (532.8 mg/L, controls < 70.0 mg/L). The ratio of GAG/creatinine was 161.3 (controls: 26.2 ± 11.7). Serum chitotriosidase activity was 315.8 nmol/(ml·h) [control < 53 nmol/(ml·h)]. Beta-glucuronidase activity was deficient in isolated leukocytes.

CONCLUSIONSevere form of mucopolysaccharidosis VII exhibited characteristics of hydrops fetalis, hepatosplenomegaly, coarse face, thrombocytopenia and Alder-Reilly granules in the leucocytes. The measurements of GAG in urinary and beta glucuronidase in leucocytes are critical to diagnosis and deferential diagnosis.

OBJECTIVETo investigate the phosphorylation of KCNE2 protein in heart of old SHR rats.

METHODSThe membrane proteins from ventricular myocardium of old SHR were extracted, treated with or without alkaline phosphatase and tested binding with Ab2 (an anti-KCNE2 polyclonal antibody) by Western blot. A KCNE2 fusion protein with c-myc was obtained from in vitro translation system and treated with or without alkaline phosphatase. A series of mono- and double-point mutated fusion KCNE2 proteins with c-myc were obtained from an in vitro translation system, and Western blots with Ab2 or anti-myc antibody were performed.

RESULTSAfter alkaline phosphatase treatment, Ab2 significantly attenuated its binding with KCNE2. In vitro translation system confirmed that after alkaline phosphatase treatment, Ab2 weakened binding ability to KCNE2 while binding to c-myc was not changed. Point mutation experiments showed that serine residue in position 98 of KCNE2 proteins might be phosphorylated.

CONCLUSIONKCNE2 protein in heart of old SHR rats is phosphorylated and this phosphorylation takes place in serine residue of position 98.
