RESUMO
To explore the mechanism of acupoint embedding for obesity based on the western pathological mechanism of chronic low inflammatory response inducing the imbalance between"promoting inflammation"and"anti-inflammation"in immune reaction, and the pathological nature of deficient healthy and state of evil domination in the TCM theory induced by the"stagnation heat, phlegm heat, dampness heat, stasis heat"on the basis of deficiency. The mechanism may be improving the secretory disorder of adipose tissue and metabolic inflammatory response by the enhanced anti-inflammatory phagocytosis clearance ability in the immune system which is caused by the new inflammatory reaction under the stimulation of innate immune response pattern. The model of"inhibiting chronic low inflammation reaction through the innate immunity"may be an important mechanism of acupoint embedding for obesity.

Objective To analyze the change trends of death situation caused by cerebral apoplexy and myocardial infarction in Chongqing from 2006 to 2010 .Methods All death cases of cerebral apoplexy and myocardial infarction from the five years of 2006 to 2010 were extracted from the direct network report system covering the whole crowd death causes in Chongqing and performed the statistical analysis .Results The constituent ratio of cerebral apoplexy death was increased from 13 .94% to 16 .71% in these five years ,while which of myocardial infarction death in all death causes was stabilized around 4% .The sex ratio of male to female for cerebral apoplexy was descended from 1 .76∶1 .00 to 1 .43∶1 .00 in these five years ,while which for myocardial infarction was dropped from 1 .44∶1 .00 to 1 .30∶1 .00 ;which of cerebral apoplexy and myocardial infarction below 75 years old tended to de-cline ,while which above 75 years old tended to rise .Conclusion The cerebral apoplexy harm to Chongqing people′s life is increas-ing ,while the harm caused by myocardial infarction changes little ;the constituent ratio of female death caused by cerebral apoplexy and myocardial infarction is rising ;the cerebral apoplexy and myocardial infarction damage to old people above 75 years old is grea-ter ,and this damage still continues to grow .
RESUMO
Objective To detect the recombinant intermediates of hepatitis B virus (HBV) between genotype B and C in vitro. Methods Vector Plenti6/V5-D-topo-X was genetically modified by genotype B and C to transfect HepG2 cells. Then the HepG2 cells were amplified and sequence of the nucleic acid after the transinfection was tested and compared with RDP3Beta40 software package and bootscanning procedure in SimPlot program package. Results Three recombinant intermediates of HBV between genotype B and C were identified in vitro. Genotype C in the precore region plus the core gene spanning nucleotide positions from 1740-1838 to 2443-2485 contributed to the recombination with genotype B. Isolate R1 recombinant intermediate had 2 break points at nt2170-2172 and nt2188-2189. Nucleic acid changed from CAC to TGT and from GA to AC, respectively. Isolate R2 recombinant intermediate had a break point at nt1740-1 838, and 3 bases changed in different nucleic acid sites: from A to T at nt1740, from C to T at nt1753, and from G to A at nt1838, respectively. Isolate R3 recombinant intermediate had a break point at nt2443-2483, and 4 bases changed in different nucleic acid sites: from C to T at nt2443, from A to G at nt2452, from T to C at nt2480, and from C to T at nt2483, respectively. Conclusion The recombinant intermediates of HBV between genotype B and C have been detected in vitro and the changes have been identified in the precore region plus the core gene in genotype B and C.
RESUMO
Objective To explore the effects of Leonurus heterophyllus sweet injection(LHS)on myocardial cell apoptosis and proliferation activity in the diabetic cardiomyopathy rats induced by STZ.Methods From March to September of 2004,STZ-induced DCM model was established.The diabetic rats were divided into three groups:untreated DCM group,treated group by LHS injection and normal control group.At the end of 16 weeks,myocardial tissue of the rats was collected as experimental material to examine apoptosis by using TUNEL,electromicroscopic changes(ultrastructure)and related gene expression(Fas,FasL,Bax,Bcl-2)as well as proliferating cell nuclear antigen(PCNA)with immunohistochemistry method.Results 1.Compared with the DCM group,only a few myotomes of cardiac myocytes in LHS-treated group were out of their positions.There was no myofibril melt and the mitochondria structure kept intact.2.Compared with the DCM group,the numbers of myocardial cell apoptosis were significantly decreased(P
