1Immunocytochemical identification and localization of APUD cells in the gut of seven stomachless teleost fishes显示文摘AIM To study the cell types,localization,distribution density and morphology of APUDcells in the intestinal mucosa of stomachlessteleost fishes.METHOD By using the peroxidase-antiperoxidase complex(PAP)immunocytochemical staining technique theidentification,localization and morphology ofimmunoreactive(IR)endocrine cells seattered inthe intestinal mucosa of grass carp(Cyenopharyngodon idellus),black carp(Mylopharyngodon piceus)and common carp(Cyprinus carpio)were investigated with 20kinds of antisera prepared against mammalianpeptide hormones of APUD cells,and likewise byusing avidin-biotin-peroxidase complex(ABC)method those of silver carp(Hypophthalmichthys molitrix),bighead(Aristichthys nobilis),silver crucian carp(Carassius gibelio)and bluntnose black bream(Megalobrama amblyocephala)were alsostudied with 5 different antisera.Thereplacement of the first antiserum by phosphatebuffered saline(PBS)was employed as a control.IR endocrine cells were counted with asquare-mesh ocular micrometer from 10 fieldsselected randomly in every section of each partof the intestine specimen.The average numberof IR endocrine cells per mm2 was counted toquantify their distribution density.RESULT Gastrin(GAS)-,Gastric inhibitorypeptide(GIP)-,glucagon(GLU)-,glucagon-likeimmunoreactants(GLI)-,bovine pancreaticpolypeptide(BPP)-,leucine-enkephalin(ENK)-and substance P(SP)-IR endocrine cells werefound in the gut of grass carp,black carp andcommon carp,and somatostatin(SOM)-IRendocrine cells were only seen in common carp.GAS-,GIP-and GLU-IR endocrine cells werefound in the intestinal mucosa of silver carp,bighead,silver crucian carp and bluntnose blackbream.Most of IR endocrine cells had the higherdistribution density in the foregut and midgut,and were longer in shape.They had a long apicalcytoplasmic process extended to the gut lumenand a basal process extended to adjacent cellsor basement membrane and touched with it.Sometimes,the basal cytoplasmic processformed an enlarged synapse-like structure in thecontiguous part with basement membrane.Thisphenomenon provided new morphologicalevidence for neuroendocrine and paracrinesecretory function of these enteroendocrinecells.CONCLUTION At least 8 kinds of IR endocrinecells were found in the gut of stomachlessteleost species for the first time in China.TheseIR endocrine cells scattering in the gut mucosabelong to the APUD system.Among them,thehormones secreted by SP-,ENK-,SOM-and GLU-IR endocrine cells belong to the peptides of dualdistribution in the brain and gut.This providednew evidence for the concept of brain-gutpeptide.According to the cell types,distribution density,morphologicalcharacteristics and variety in shape of APUDcells in the gut of stomachless teleost fishes,itis deemed that the digestive tract of fishes isalso an endocrine organ of great importance andcomplexity.Pan QS Fang ZP Zhao YX 2000World Journal of Gastroenterology2000,6,1:25
2Extracorporeal shock-wave versus pneumatic ureteroscopic lithotripsy in treatment of lower ureteral calculi显示文摘Aim:To compae the efficacy and complications of extracorporeal shock-wave lithotripsy (SWL) and pneumatic ureteroscopic lithotripsy(URS) in the treatment of lower ureteral calculi.Methods:From August 1997 to June 1999,210 patients with calculi in the distal third of the ureter were treated with SWL and other 180 with URS.The stones were fragmented with either HB-ESWL-V lithotripter or JML-93 pneumatic lithotripter through Wolf 7.5-9.0 Fr ureteroscope.The outcome was assessed in terms of stone clearance rate,re-treatment rate and complication incidence.Results:the stone clearance rate was 78.1% with SWL and 93.3% with URS (p<0.05).SWL had a re-treatment rate of 11.9%,vs 2.2% in the URS group (P<0.05).URS caused ureteral perforation in 3.3% of patients,while it was o with SWL (P<0.05).The differences in the incidence of other complications such as infection and stricture between the two groups were insignificant.conclusion:Though the selection of these two options depends on equipments available and the expertise of the operator,we recomment URS as the optimal treatment for distal ureteral calculi.Zeng, GQ Zhong, WD Cai, YB Dai, QS Hu, JB Wei, HA 2002Asian Journal of Andrology2002,4,4:17

4Cloning and expression of core gene cDNA of Chinese hepatitis C virus in cosmid pTM3显示文摘AIM To clone core gene cDNA of Chinesehepatitis C virus(HCV)into eukaryoticexpression vector cosmid pTM3 and to expressHCV core antigen in HepG2 cells.METHODS Core gene cDNA of HCV wasintroduced into eukaryotic expression vectorcosmid pTM3.Using vaccinia virus/bacteriophage T7 hybrid expression system,HepG2 cells were transfected with therecombinant plasmid pTM3-Q534 by lipofectin.RESULTS From the transfected bacteriaTop10F’,2 pTM3-Q534 clones containing therecombinant plasmid were identified fromrandomly selected 10 ampicillin-resistantcolonies.By reverse transcription PCR andindirect immunofluorescence technique,HCVRNA and core protein was identified in HepG2cells transfected with the recombinant plasmid.CONCLUSION The construction of arecombinant plasmid and the expression of coregene cDNA of HCV in HepG2 was successful.Jiang RL Lu QS Luo KX 2000World Journal of Gastroenterology2000,6,2:12

6Gravity field and crustal structure of Gyirong-Lugu Region in western Xizang (Tibet) Plateau显示文摘THE Gyirong-Lugu gravity profile in western Xizang Plateau was carried out by Institute ofGeophysics,Chinese Academy of Sciences in 1994—1995.The data of this gravity profile fillthe gaps in the research of gravity field of western Xizang Plateau and provide basic informa-tion for the study of the whole structure and dynamical mechanism of Xizang Plateau.Wang, QS Wu, CZ Jiang, WW 1997Chinese Science Bulletin1997,42,8:3
