1.The changes of calmodulin and cAMP in rabbit myocardium during ischemia and reperfusion
Chinese Journal of Pathophysiology 1986;0(01):-
This study was performed on rabbits to examine the changes of calmodulin (CAM) and cAMP in the myocardium during ischemia and reperfusion by radioimmunoassay method. The result showed the levels of CaM and cAMP increased at 20 min of ischemia. Although these two parmeters were unchanged at 40 min of ischemia as compared with the changes at 20 min, they were changed during reperfusion at different times of ischemia. At 20 min ischemia following 10 min reperfusion, the content of CaM decreased, the content of cAMP increased. On the basis of 40 min ischemia, reperfusion induced opposite changes: CaM increased, cAMP decreased. The possible mechanism of these changes was discussed.

Purpose To investigate the expression of TET2 and DNMT3A in patients with peripheral T cell lymphoma (PTCL) and the relationship to immunophenotypes of PTCL.Methods Using a panel of immunohistochemical markers (CD3,CD4,CD10,BCL-6,CXCL-13,CD30,ALK),all cases of PTCLs were further divided into four groups,including angioimmunoblastic T cell lymphoma (AITL),peripheral T cell lymphoma,not otherwise specified (PTCL-NOS),anaplastic lymphoma kinase negative anaplastic large cell lymphoma (ALK-ALCL) and anaplastic lymphoma kinase positive anaplastic large cell lymphoma (ALK + ALCL).The expression of TET2 and DNMT3A in 89 cases of PTCL was detected by immunohistochemical analysis.Results 89 cases were divide into four subtypes,AITL (36/89),PTCL-NOS (26/89),ALKALCL (18/89),and ALK + ALCL (9/89).Immunohistochemistry staining revealed higher cytoplasmic expression of TET2 and DNMT3A in AITL than that of in PTCL-NOS and ALCL (P < 0.05).And the nuclear expression of DNMT3A in patients with AITL was higher than that of PTCL-NOS and ALCL (P < 0.05).The cytoplasmic expression of TET2 was positively related with both cytoplasmic and nuclear expression of DNMT3A in patients with AITL (P < 0.05).Conclusion TET2 combined with DNMT3A could be used as markers in AITL diagnosis,which could provide new strategy for AITL diagnosis.

The specific ScFv gene against botulinum neurotoxin A (BoNTa)was cloned into pPIC9k. Positive integrators were screened by increasing the dose of G418 in culture and expressed in Pichia pastoris GS115. As a result, engineered recombinant clone were obtained. 26 kD product of interest was seen easily in SDS-PAGE. Expression of human ScFv got the highest level 15% of total secreted proteins during 72~84 h after 1% methanol inducing. Purification of ScFv was finished by two steps: gel filter and ion exchange. Competing ELISA showed that recombinant ScFv could compete with antiserum to specific bind BoNTa.

Objective To discuss the effects and methods of the surgical treatment of complex humeral nonunion.Methods Ten cases of scleroid humeral nonunion were treated by compressive interlocking medullary nailing and autografting of iliac bone.Fifteen cases of humeral nonunion combined with osteomyelitis or osteoporosis were treated with grafting of free vascularized fibular flaps.Results All the cases were followed up for six months to six years.They all obtained bone union.The average time of bone union was 3.1 months for the free vascularized fibular grafting group and 3.8 months for the interlocking medullary nail group.Conclusions Compressive interlocking medullary nailing and autografting of iliac bone is effective for scleroid humeral nonunion,while grafting of free vascu- larized fibular flaps is effective for humeral nonunion combined with osteomyelitis or osteoporosis because the free vas- cularized fibular grafting can well reconstruct the defective humerus bone with osteoporosis or osteomyelitis.

Objective To study the value of lung window and soft tissue window in measuring colon diseases with experimental CTVC examination.Methods Twenty-four artificial polypoid diseases were placed with glue in a thoroughly cleaned porcine colon(overall length,150 era)that was distented with air and submerged in a water phantom and scanned 10 times on a 64-MSCT(GE Light speed)with identical scanning parameters.The data were reconstructed every 0.625 mm and reviewed using 2D images, navigation,MPR and 3D volume-rendered images on a GE AW 4.2 workstation.The maximum diameters of the artificial polypoids were measured by two radiologists with more than 10 years working experience in lung window(W = 1000,L =-700)and soft tissue window(W =400,L =40),respectively.The average value of maximum diameters of the artificial polypoids were measured for 10 times and were compared with the actual diameter.Results Twenty-four artificial polypoid diseases and their shape,size,loeation and relation of diseases with bowel wall were all showed excellently.The maximum diameter measured was close to the actual diameter.The average value was mostly less than actual diameter and a few of them more than the actual diameter.The maximum diameter measured in lung window was close to the actual diameter,and there was no difference between the two data sets(t =0.431,P =0.669).There was difference between the maximum diameter measured in soft tissue window and the virtual diameter(t = 2.691,P = 0.010). Conclusion In screening the colon diseases,CTVC is a good method of choice with no insult or less insult, and higher repeatability.The lung window should be chosen in measuring colon diseases in CTVC examination.
