1Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats.Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG 1999World Journal of Gastroenterology1999,5,6:45

12TT viral infection through blood transfusion:retrospective investigation on patients in a prospective study of post-transfusion hepatitis显示文摘AIM To investigate the role of bloodtransfusion in TT viral infection(TTV).METHODS We retrospectively studied serumsamples from 192 transfusion recipients whounderwent cardiovascular surgery and bloodtransfusion between July 1991 and June 1992.Allpatients had a follow-up every other week for atleast 6 months after transfusion.Eightyrecipients received blood before screeningdonors for hepatitis C antibody(anti-HCV),and112 recipients received screened blood.Recipients with alanine aminotransferase level>2.5 times the upper normal limit were testedfor serological markers for viral hepatitis A,B,C,G,Epstein-Barr virus and cytomegalovirus.TTV infection was defined by the positivity forserum TTV DNA using the polymerase chainreaction method.RESULTS Eleven and three patients,whoreceived anti-HCV unscreened and screened'blood,respectively,had serum ALT levels>90 IU/L.Five patients(HCV and TTV:1;HCV,HGV,and TTV:1;TTV:2;and CMV and TTV:1)were positive for TTV DNA,and four of them hadsero-conversion of TTV DNA.CONCLUSION TTV can be transmitted viablood transfusion.Two recipients infected byTTV alone may be associated with the hepatitis.However,whether TTV was the causal agentremains unsettled,and further studies arenecessary to define the role of TTV infection inchronic hepatitis.Yang SS Wu CH Chen TH Huang YY Huang CS 2000World Journal of Gastroenterology2000,6,1:8
13Species distribution of polymeric aluminium ferrum——timed complexation colorimetric analysis method of Al-Fe-Ferron显示文摘The effects of the colorimetric buffer solutions were investigated while the two colorimetric reactions of A1 ferron complex and Fe ferron complex occurred individually, and the effects of the testing wavelength and the pH of the solutions were also investigated. A timed complexation colorimetric analysis method of A1 Fe ferron in view of the total concentration of {A1+Fe} was then established to determine the species distribution of polymeric Al Fe. The testing wavelength was recommended at 362 nm and the testing pH value was 5. With a comparison of the ratios of n Al / n Fe , the standard adsorption curves of the polymeric Al Fe solutions were derived from the experimental results. Furthermore, the solutions’composition were various in both the molar n Al / n Fe ratios, i.e. 0/0, 5/5, 9/1 and 0/10, and the concentrations associated with the total [A1+Fe] which ranged from 10 -5 to 10 -4 mol/L.Hu, YY Tu, CQ Wu, HH 2001Journal of Environmental Sciences2001,13,4:8

15Survival outcomes of right-lobe living donor liver transplantation for patients with high Model for End-stage Liver Disease scores显示文摘BACKGROUND: Controversy exists over whether living donor liver transplantation (LDLT) should be offered to patients with high Model for End-stage Liver Disease (MELD) scores. This study tried to determine whether a high MELD score would result in inferior outcomes of right-lobe LDLT. METHODS: Among 411 consecutive patients who received right-lobe LDLT at our center, 143 were included in this study. The patients were divided into two groups according to their MELD scores: a high-score group (MELD score ≥25; n=75) and a low-score group (MELD score <25; n=68). Their demographic data and perioperative conditions were compared. Univariable and multivariable analyses were performed to identify risk factors affecting patient survival. RESULTS: In the high-score group, more patients required preoperative intensive care unit admission (49.3% vs 2.9%; P<0.001), mechanical ventilation (21.3% vs 0%; P<0.001), or hemodialysis (13.3% vs 0%; P=0.005); the waiting time before LDLT was shorter (4 vs 66 days; P<0.001); more blood was transfused during operation (7 vs 2 units; P<0.001); patients stayed longer in the intensive care unit (6 vs 3 days; P<0.001) and hospital (21 vs 15 days; P=0.015) after transplantation;more patients developed early postoperative complications (69.3% vs 50.0%; P=0.018); and values of postoperative peak blood parameters were higher. However, the two groups had comparable hospital mortality. Graft survival and patient overall survival at one year (94.7% vs 95.6%; 95.9% vs 96.9%), three years (91.9% vs 92.6%; 93.2% vs 95.3%), and five years (90.2% vs 90.2%; 93.2% vs 95.3%) were also similar between the groups. CONCLUSIONS: Although the high-score group had signifi-cantly more early postoperative complications, the two groups had comparable hospital mortality and similar satisfactory rates of graft survival and patient overall survival. Therefore, a high MELD score should not be a contraindication to right-lobe LDLT if donor risk and recipient benefit are taken into full account.Kenneth SH Chok See Ching Chan James YY Fung Tan To Cheung Albert CY Chan Sheung Tat Fan Chung Mau Lo 2013Hepatobiliary & Pancreatic Diseases International2013,12,3:6

18Prevention of recurrent hepatitis B infection after liver transplantation显示文摘BACKGROUND:Recurrence of hepatitis B virus(HBV) infection after liver transplantation can lead to graft loss and a reduction in long-term survival.The purpose of this review is to summarize the current therapeutic options for preventing HBV recurrence in liver transplant recipients.DATA SOURCES:Up to January 2013,studies that were published in MEDLINE and EMBASE on prevention of HBV recurrence after liver transplantation were reviewed.RESULTS:There have been remarkable advancements in the past two decades on the prevention of HBV recurrence after liver transplantation,from the discovery of hepatitis B immune globulin(HBIG) and lamivudine monotherapy to the combination therapy using HBIG and lamivudine.With the development of newer and stronger antiviral agents,the need for life-long HBIG is doubtful.With their low resistance profile,oral antiviral prophylaxis using these new agents alone is sufficient and is associated with excellent outcome.CONCLUSIONS:Restoration of host HBV immunity with adoptive immunity transfer and vaccination may represent the ultimate strategy to withdraw prophylactic treatment and to achieve a drug free regimen against HBV recurrence after liver transplantation.Tiffany CL Wong James YY Fung Chung Mau Lo 2013Hepatobiliary & Pancreatic Diseases International2013,12,5:5
19Sequence variations of the S7 ribosomal protein gene in primitive cyprinid fishes: Implication on phylogenetic analysis显示文摘Cyprinidae is the largest fish family in the world and contains about 210 genera and 2010 species. Appropriate DNA markers must be selected for the phylogenetic analyses of Cyprinidae. In present study, the 1st intron of the S7 ribosomal protein (r-protein) gene is first used to examine the relationships among cyprinid fishes. The length of the 1st intron obtained by PCR amplification ranges from 655 to 859 bp in the 16 cyprinid species investigated, and is 602 bp in Myxocyprinus asiaticus. Out of the alignment of 925 nucleotide sites obtained, the parsimony informative sites are 499 and occupy 54% of the total sites. The results indicate that the 1st intron sequences of the S7 r-protein gene in cyprinids are rich in informative sites and vary remarkably in sequence divergence from 2.3% between close species to 66.6% between distant species. The bootstrap values of the interior nodes in the NJ (neighbor-joining) and MP (most-parsimony) trees based on the present S7 r-protein gene data are higher thanWang, XZ He, SP Chen, YY 2002Chinese Science Bulletin2002,47,19:5
