In recent years, it was found that heart was significantly protected against ischemia-reperfusion injury if it was first preconditioned by brief ischemia or by administering a potassium channel opener. Both of these preconditioning strategies were found to require opening of a K(ATP) channel, we showed that this pivotal role was mediated by the mitochondrial ATP-sensitive K+ channel (mitoK(ATP)). As the mechanism was not clarified yet, this paper reviewed the evidence showing that the mechanism and the characters of mito K(ATP) and its cardioprotection against ischemia-reperfusion injury

The integrator complex is multifunctional and contains at least 12 evolutionarily conserved subunits in hu-mans.It interacts with the C-terminal tail of the largest subunit of RNA-polymeraseⅡ ( RNAPⅡ) to promote 3′-end pro-cessing of small nuclear RNA (snRNA) U1/U2.It also interacts with RNAPⅡ, NELF and Spt5 to regulate NELF-mediated RNAPⅡpause/release and processivity at coding genes .Recently, the integrator complex is also reported to be involved in DNA damage response , dynein recruitment to the nuclear envelope , integrity of Cajal bodies , adipose differentiation , hem-atopoiesis , ciliogenesis , tumorigenesis and generation of viral microRNAs .This review discusses related research progress in the integrator complex .

Objective To evaluate the effects of hydrogen peroxide (H 2O 2) on cardiomyocytes and the protective effect of pinacidil preconditioning on injured primary cultured cardiomyocytes. Methods We isolated and cultured cardiomyocytes in neonatal mice by trypsin digestion technique. The cells were inoculated in 96-well culture plate at the density of 1?10 5/ml. Cells were divided into control group and 400, 600, and 800 ?mol/L H 2O 2 treatment groups. MTT assay was used to determine the cell vitality at 1, 3, 6, 12, and 24 h after H 2O 2 treatment. The effects of pinacidil preconditioning were also observed. Results The effect of H 2O 2 on the damages to cardiomyocytes was in dose- and time-dependent manners. Pretreatment with pinacidil at the concentrations of 1?10 -4 , 1?10 -5 , and 1?10 -6 mol/L, particularly 1?10 -6 mol/L, could increase the activity of cardiomyocytes treated with H 2O 2. Conclusion Pinacidil preconditioning at lower doses can protected cardiomyocytes from injuries induced by H 2O 2.

The paper retrieved the literature information on the artificial bone and composite artificial bone in CNKI, Wanfang data and foreign databases such as Pubmed and SCI-E from 2009 to 2016, and summarized the characteristics and deficiency of all kinds of artificial bone materials.On this basis, it briefly described the functional application and the principles of the composite artificial bone repair materials, and introduced the application of tissue engineering and 3D printing technology in the field, which could provide reference for the exploration of new types of composite artificial bone repair materials.

Objective To evaluate diagnostic value and analyze the complications of the lung nodules by 64 slice CT guided percutaneous thoracic biopsy(PTB)with coaxial technique.Methods The clinical data of 63 patients with lung placeholder in coaxial line casing biopsy under CT guidance were retrospectively analyzed.After CT positioning,16G coaxial trocar rapidly passed through the pleura,the tip to the edge of the tumor or pathological lesions,pulled out the needle core,the coaxial sleeve in 18G semi automatic biopsy needle,the materials were multi-angle cuted and sent to the pathology examination,the positive rate and the incidence of complications were analyzed.Results In 63 cases of lesions under CT guidance,the success rate of drawing materials was 100.0%,the pathological diagnosis rate was 88.9%.Intraoperative and postoperative complications occurred in 18 cases,the incidence rate was 28.6%,among them 9 cases of pneumothorax(14.3%),pulmonary hemorrhage in 8 cases(12.7%),hemoptysis in 1 case(1.6%),no severe adverse reaction was observed.Conclusion Multi slice CT guided percutaneous coaxial biopsy has the advantages of simple operation,high diagnosis rate,less complications,low risk,it can be promoted in hospitals.

Objective:To study the effect of articulation disorder on psychology action of cleft palate patients after operation.Methods:65 patients were asked to answer the psychology questionnaire.Results:The patients of misarticulation all have some degree of psychological disability,and unusual psychology action would affect pronunciation treatment.Conclusion:Patients with misarticulation have psychology problems in some degree,which would affect the clinic treatment of cleft palate.
