Objective:To explore clinical characteristics of reperfusion arrhythmia (RA) during direct percutaneous coronary intervention (PCI ) in patients with acute myocardial infarction (AMI ) and its influence on prognosis . Methods :Clinical data of 180 AMI patients undergoing direct PCI in our hospital from Jan 2013 to Dec 2014 were retrospectively analyzed .Results:RA rate in 112 patients was 62.22% and it's correlated with age (r=0.614 ,P=0.026) ,the age is more older ,the RA rate is more higher .Compared with multi -vessel coronary disease patients , there was significant rise in incidence rate of RA (48.33% vs .69.17% , P=0.021) in single -vessel disease pa‐tients ;compared with left anterior descending group and left circumflex group ,there was significant rise in inci‐dence rate of RA (61.67% vs .53.33% vs .71.67% ) in right coronary artery group ,and there was significant difference between any two groups , P<0.05 all .Compared with patients with coronary recanalization within 6~12h ,there was significant reduction in incidence rate of RA (66.67% vs .47.62% ,P=0.025) in those within 6h . There were no significant difference in incidence rates of death ,reinfarction and stroke during hospitalization and six months after PCI between RA group and no RA group ,P>0.05 all .Conclusion:The occurrence of reperfusion arrhythmia in patients with acute myocardial infarction during direct percutaneous coronary intervention is associat‐ed with number of diseased vessels ,infarct vascular type and coronary recanalization time .

ObjectiveTo observe the defervesce effect of bloodletting plus puncturing and cupping treatment in treating common cold due to wind-heat.MethodSixty-two patients with fever due to external contraction were randomized into a treatment group of 30 cases and a control group of 32 cases. The control group was intervened by muscular injection of Antodin plus oral administration ofQing Kai Linggranules 3 g, three times a day; the treatment group was by cupping and bloodletting at Dazhui (GV14) and Feishu (BL13), bloodletting at Shaoshang (LU11) and Shangyang (LI1), and cupping at back in addition to the intervention given to the control group. The clinical efficacy, treatment acting time (body temperature decreased by 0.5℃) and defervesce time were observed. ResultIn the treatment group, the acting time and defervesce time were respectively (6.11±2.18)h and (27.11±10.84)h, and total effective rate was 93.4%; in the control group, the acting time and defervesce time were respectively(14.31±5.43)h and (39.14±13.45)h, and total effective rate was 84.4%, and the differences were statistically significant (P<0.05).Conclusion Acupoint bloodletting plus bloodletting-cupping method can produce a significant defervesce effect in treating common cold due to wind-heat.

Clonal hematopoiesis is a special mode of hematopoiesis in which hematopoietic stem cells with specific genetic and molecular biological characteristics differentiate into mature blood cells. It is the basis of a variety of hematological diseases. In depth study of its etiology, mechanism and characteristics are conducive to our understanding of the value of clonal hematopoiesis in different populations or diseases. This article reviews the latest progress in clonal hematopoiesis and its related clonal diseases.

BACKGROUND:Mechanical stimulation triggers a muscle tissue remodeling, during which, myoblast process is a multi-stage development process. Many signals in extracellular matrix are involved in myoblast process, and mechanical signals are considered as important external factors for muscle formation and regeneration.
Numerous studies concerning cyclic tensile stress effects on myoblast proliferation and apoptosis have been reported, but the specific mechanism underlying the mechanical stimulation in muscle formation is stil unclear. OBJECTIVE:To study the effects of cyclic stretch on proliferation of C2C12 myoblasts and its mechanism.
METHODS:C2C12 myoblasts were cultured in vitro under 10%cyclic stretch for 6, 12 and 24 hours.
RESULTS AND CONCLUSION:The results of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that with the time of cyclic stretch, the proliferation of C2C12 myoblasts and the rate of S-phase fraction were gradual y increased and peaked at 12 hours (P<0.05), and then decreased. Western blot assay showed that the expression of nuclear transcription factorκB protein was decreased with time, which was inversely correlated to the proliferation of C2C12 myoblasts, but increased at 24 hours under the cyclic stretch. These findings indicate that the cyclic stretch can induce C2C12 myoblasts proliferation and alter the cellcycle. Nuclear transcription factorκB may be involved in this process.

OBJECTIVE:To explore the effects of Haikangling Mixture on immunological function in immunosuppressed mice induced by cyclophosphamide. METHODS: Mice were given Haikangling Mixture intragastrically for 14d, and the level of hemolysin was determined by sheep erythrocyte (SRBC) immunization to exploer the influence of Haikangling on humoral immunity in mice; splenic lymphocytes were measured by MTT to observe the influence on cell immunity; the clearance of macrophage were measured by carbon particle clearance method to explore the influence on non-specificity immunity. RESULTS: The level of hemolysin, the cell reproductive activity, splenic lymphocytes and the phagotrophy of mononuclear macrophage were improved obviously by Haikangling Mixture in immunosuppressed mice induced by cyclophosphamide. CONCLUSION: Haikangling Mixture can enhance the immunological function in immunosuppressed mice induced by cyclophosphamide.

Objective To investigate the effects of ZEB1 (Zinc finger E-box binding homeobox 1) gene knockdown on proliferation, cell cycle and apoptosis of human adipose-derived mesenchymal stem cells (hADSCs).Methods Primary mesenchymal stem cells were obtained from human adipose tissue by collagenase digestion and identified by immunological phenotype and differentiation potential of osteogenic and adipogenic lineages .The siRNA was trans-fected into hADSCs by lipofectamine 2000 .The expression of ZEB 1 and key proliferation , cell cycle and apoptosis-related genes were detected by real-time PCR and Western blot at mRNA and protein level respectively .The cell proliferation capacity was assessed by MTS .The apoptosis and cell cycle of hADSCs were evaluated by flow cytome-try.Results The ZEB1 expression at mRNA and protein level was significantly decreased in si-ZEB1 transfection cells as compared to transfection with si-NC.Inhibition of ZEB1 decreased the cell proliferation ability , and signifi-cantly inhibited the expression of cell proliferation related genes, including CCND1, MKI67, MYC and PCNA.After transfection with si-ZEB1 , the percentage of cells in G1 phase increased from 50.17% to 58.94%, and S phase and G2 phase decreased by 6.16% and 2.07% separately.Meanwhile, the apoptosis rate increased by 10.2%, the expression of apoptosis related genes TP53 and BAX was up-regulated , and the expression of anti-ap-optotic genes MCL1 and BCL2 was down-regulated in si-ZEB1 transfection cells as compared to transfection with si-NC.Conclusions ZEB1 may play an important role in promoting hADSCs proliferation , cell cycle progression and inhibit their apoptosis .

Objective:To investigate the effect of estrogen on the expression and distribution of IL-1 in the remodeling osteoporotic alveolar bone.Methods:Ovariectomy was performed on 30 female SD rats and sham operation on 15(control group).When osteoporosis was developed in the 30 ovary-removed rats,the left maxillary molars of all the rats were extracted.On the following day 15 of them were treated with intramuscular estrogen injection at 20 ?g/kg once every 3 days(treatment group).Another 15 rats with ovary removed received no treatment(osteoporosis group).7,30 and 60 days after teeth extraction 5 rats were killed respectively in each group.IL-1 expression in alveolar bone was examined immunohistochemically,and semiquantitative analysis of cellular-staining intensity was done by microphotometry.Results:The positive IL-1 expression were mainly located in the osteoclasts,vascular endothelial cells and fibroblasts.7 days after teeth extraction the cellular-staining intensity of IL-1 in control group,osteoporosis group and treatment group was 0.11?0.019,0.36?0.038 and 0.18?0.025 respectively(control or treatment group vs osteoporosis group,P
