OBJECTIVEThe study investigated the epidemiology of Filifactor alocis (F. alocis) in subgingival plaque samples from subjects with different periodontal statuses. The relationship between the prevalence of F. alocis and clinical periodontal parameters was also analyzed.
METHODSSubgingival plaque samples and periodontal data were collected from 68 healthy sites (H groups) in 17 healthy subjects, 64 healthy (G-H group) and 76 diseased sites (G-D group) in 19 patients with chronic gingivitis, and 36 healthy (P-H group) and 56 diseased sites (P-D group) in 14 patients with chronic periodontitis. The plaque samples were analyzed by polymerase chain reaction, and possible correlations between the F. alocis detection rate and the bleeding index, probing depth, or clinical attachment level were determined.
RESULTSThe detection levels of F. alocis increased in both healthy and diseased groups. The lowest level at 30.88% (21/68) was noted in the H group, whereas the highest level at 91.07% (51/56) was obtained from the P-D group. A significant correlation was found between the F. alocis detection levels and periodontal disease condition (P < 0.000 1). Further analyses showed that a significant correlation also existed between the detection level of F. alocis and the abnormal clinical periodontal parameters, namely, bleeding index, probing depth, and clinical attachment loss. The odds ratios were 5.26, 8.85, and 11.65, respectively.
CONCLUSIONF. alocis was found at increased-levels in subjects with periodontal disease. The presence of F. alocis increases the risk of sites with abnormal clinical periodontal parameters.

Objective To explore and analyse the causes of reoperation after biliary duct operation, so as to decrease the reoperation rate of biliary tract. Methods Clinical data of 71 patients who underwent reoperation of biliary duct diseases in our hospital between January 2005 to September 2010 were analysed,and the causes of biliary duct reoperation were summarized and analysed. Results The main cause of reoperation was recurrent or retained bile stone (76.1%,54/71), noncalculous stenosis of biliary tract ( 15.5 %, 11/71 ),biliary tract obstruction due to tumor (4.2%,3/71), and other factors (4.2%,3/71).Conclusion Recurrent or retained bile duct stone were the main cause for biliary reoperation, but noncalculous stenosis of biliary tract and biliary tract obstruction due to tumor could not be ignored. The initial rational operative method, approporiate operation time and the thoroughness of operation are the key factors to decrease bile duct reoperations.

Aim To explore the role of cytoplasmic FKBP52 in AAV-mediated transduction.Methods Murine embryo fibroblasts(MEFs)cultures from FKBP52 wild-type(WT),heterozygous(HE),and knockout(KO)mice were established.The role of FKBP52 in intracellular trafficking of AAV was analyzed by fluorescence-activated cell sorting(FACS)analyses,electrophoretic mobility shift assays(EMSA),southern blot,immunoprecipitations and western blot analyses.Results Conventional AAV vectors failed to transduce WT MEFs efficiently,and the transduction efficiency was not significantly increased in HE or KO MEFs.AAV vectors failed to traffick efficiently to the nucleus in these cells.Treatment with hydroxyurea(HU)increased the transduction efficiency of conventional AAV vectors by~25-fold in WT MEFs,but only by~4-fold in KO MEFs.The use of self-complementary AAV(scAAV)vectors,which bypass the requirement of viral second-strand DNA synthesis,revealed that HU treatment increased the transduction efficiency~23-fold in WT MEFs,but only~4-fold in KO MEFs,indicating that the lack of HU treatment-mediated increase in KO MEFs was not due to failure of AAV to undergo viral second-strand DNA synthesis.Following HU treatment,~59% of AAV genomes were present in the nuclear fraction from WT MEFs,but only ~28% in KO MEFs,indicating that the pathway by which HU treatment mediates nuclear transport of AAV was impaired in KO MEFs.When KO MEFs were stably transfected with an FKBP52 expression plasmid,HU treatment-mediated increased in the transduction efficiency was restored in these cells,which correlated directly with improved intracellular trafficking.Intact AAV particles were also shown to interact with FKBP52 as well as with dynein,a known cellular protein involved in AAV trafficking.Conclusion These studies suggest that FKBP52,being a cellular chaperone protein,facilitates intracellular trafficking of AAV,which has implications in the optimal use of recombinant AAV vectors in human gene therapy.

Objective To explore the expression of nuclear factor-erythroid 2-related factor 2(Nrf2) and the molecular chaperone of cytoplasmic Keap1 in premature newborn rats exposed to hyperoxia.Methods Completely randomized design method was performed,one-day old preterm SD rats were randomly divided into two groups:hyperoxia group and air group.The preterm SD rats in hyperoxia group were continuously exposed to oxygen(oxygen >0.85)and air group in room air.After 1 ,4,7,10,14 days of exposure,the pre-term SD rats of two groups were sacrificed,whole lung of these rats were isolated,the lung histological chan-ges were observed by HE staining.Total lung RNA was extracted,Nrf2 and Keap1 mRNA were detected by RT-PCR.Western-blot was used to detect the changes of Nrf2 protein expression.Results (1 )Compaired with air group,the expression of Nrf2 in lung tissue of hyperoxia group significantly increased after 4,7 days of exposure(4 d:0.314 ±0.064 vs.0.521 ±0.086,7 d:0.440 ±0.121 vs.0.658 ±0.076)(P <0.05 ),the general tendency decreased after 10 days,but the expression of Nrf2 became significantly weak after 14 days of exposure in hyperoxia group(P <0.05).(2)The expression of Keap1 mRNA in hyperoxia group signifi-cantly increased in 1 ,4 days(1 d:0.352 ±0.052 vs.0.547 ±0.075,4 d:0.363 ±0.074 vs.0.658 ±0.076) (P <0.05),the general tendency decreased after 7 days of exposure,but the expression of Keap1 mRNA in hyperoxia group became significantly weaker than its expression after 10,14 days of air group(P <0.05 ). (3)In comparison with air group,Nrf2 protein expression in hyperoxia group increased after 1 ,4 days of ex-posure with no significant difference(P >0.05),but had a tendency of decreasing after 7 days.On day 10, 14,its expression in hyperoxia group became significantly weak compared with that of air group(10 d:1.325 ±0.464 vs.0.755 ±0.348,14 d:1.662 ±0.474 vs.0.867 ±0.1 15 )(P <0.05 ).Conclusion Oxidation outbreak results in the abnormal expression of Nrf2 and Keap1 in the lung of premature SD rats induced by hyperoxia exposure,which adjusts the levels of oxidative stress in the body,these changes participate in the development of hyperoxia induced lung injury,the activity of Nrf2 may be increased by hyperoxia exposure, and alleviate hyperoxia lung injury in premature rats through antioxidation of Nrf2.
