Bronchial asthma is a chronic inflammatory disease of the airways, which is characterized by airway hyperresponsiveness(AHR), eosinophilia, elevated IgE, goblet cell metaplasia, airway remodeling and so on.Changes in airway epithelial structure and function are prominent features of asthma.Asthma airway epithelium has abnormal sensitivity to oxidative damage and apoptosis, and is more susceptible to reactive oxygen species(ROS)produced by infiltrating inflammatory cells.The effects of ROS accumulation and oxidative stress are the key links in the pathogenesis of asthma.Oxidants such as ROS can interfere with the structure of epithelial cells and cause tracheal remodeling.Conversely, tracheal remodeling can release inflammatory mediators and aggravate asthma.The main function of mitochondria is oxidative phosphorylation to synthesize ATP, and it is also an important source of ROS.Mitochondrial dysfunction includes energy metabolism conversion dysfunction, mitochondrial biological dysfunction, mitochondrial autophagy and kinetic abnormalities, and mitochondrial-dependent signaling pathway disorders.Mitochondrial dysfunction and cellular hypoxia play an extremely important role in the occurrence and development of bronchial asthma.This article reviews the changes in mitochondrial function of airway epithelial cells in asthma airways in recent years, in order to provide theoretical basis for mitochondria-targeted asthma treatment.

In intensive care units (ICU) , the occurrence of acute hypotensive episodes (AHE) is the key problem for the clinical research and it is meaningful for clinical care if we can use appropriate computational technologies to predict the AHE. In this study, based on the records of patients in ICU from the MIMIC II clinical data, the chaos signal analysis method was applied to the time series of mean artery pressure, and then the patient's Lyapunov exponent curve was drawn ultimately. The research showed that a curve mutation appeared before AHE symptoms took place. This is powerful and clear basis for AHE determination. It is also expected that this study may offer a reference to research of AHE theory and clinical application.

Objective To study deletion mutations and polymorphism of PINK1 gene exons in patients with Parkinson' s disease (PD) in the littoral of Zhejiang Province,and analyze the association between these changes and the etiology of PD.MethodsAll exons of PINK1 gene in 200 PD patients( 112early-onset PD and 88 late-onset PD) and 220 controls (68 young controls and 152 old controls ) were amplified by polymerase chain reaction (PCR). All the positive PCR products were sequenced,and genotypes were detected by dot blot allele and genotype frequencies of PINK1 were compared by the Chisquare test.ResultsNo deletion mutations of the exons were found in all patients and controls.However,a known heterozygote point mutation G12169A in exon 5 was identified in 2 patients with early-onset PD.And G12164A polymorphism and G12101A polymorphism were located on PINK1 gene of exon 5. There were G/G and G/A genotypes in G12164A polymorphism,no A/A genotype.There were G/A and A/A genotypes in G12101A polymorphism,no G/G genotype. The chain relation polymorphism A/A genotype frequency was significantly higher in the PD group 84/200 (42.0％ ) than the control group (52/220,23.6％,x2 =4.034,P =0.045 ).The frequency was also significantly higher in the late-onset PD (40/88,45.5％ ) than the old control (32/152,21.1％,x2 =3.951,P =0.047 ).There were no significant differences in alleles frequencies of other groups.ConclusionThe deletion mutation and point mutation are rare in PD patients in littoral of Zhejiang Province.Chain relation polymorphism at G12164A and G12101A in PINK1 gene might be a susceptible factor for PD patients.

OBJECTIVE:To study the mechanism of histone deacetylase inhibitor RGFP109 in reversing resistance of glioma U251 cells. METHODS:TR/U251 cells resistance to temozolomide(TMZ)was extrablished. The test was divided into normal con-trol group,TMZ group(40 μmol/L)and TMZ(40 μmol/L)+RGFP109(0-120 μmol/L)different concentrations groups. After 24 h of adding into related medicines,CCK-8 was used to detect the cell survival rate and calculate the half inhibitory concentration (IC50). TUNEL and Annexin V/PI were used to detect the cell apoptosis in normal control group,TMZ group and TMZ+RGFP109 (42μmol/L)group. Immunoblotting was used to detect the O6-methyl guanine-DNA methyltransferase(MGMT),Survivin,B lym-phoma 2(Bcl-2),B lymphoma xL(Bcl-xL)protein expression;and gel migration test was used to detect the p65 acetylation level and its binding capacity with κB-DNA. RESULTS:Compared with normal control group,cell survival rate in TMZ+RGFP109 dif-ferent concentrations groups was obviously decreased (P<0.05),showing a concentration-dependent manner. When the RGFP109 concentration was 42 μmol/L,the sensitivity of TMZ to TR/U251 cells was the same with U251 cells. Compared with normal con-trol group,MGMT,Survivin,Bcl-2,Bcl-xL protein expressions in cells of TMZ groups were enhanced(P<0.01);p65 acetyla-tion level had no obvious changes,while the binding capacity of p65 and κB-DNA was strengthened (P<0.01). Compared with TMZ group,MGMT,Survivin,Bcl-2,Bcl-xL protein expressions in cells of TMZ groups were weakened(P<0.01);p65 acetyla-tion level was enhanced (P<0.01);and the binding capacity of p65 and κB-DNA was weakened (P<0.01). CONCLUSIONS:RGFP109 can reverse the resistance of U251 cells to TMZ by down-regulating the anti-apoptotic protein expressions adjusted by transcription factorκB(NF-κB)and weakening the binding of p65 andκB-DNA.

BACKGROUND: Studies have demonstrated that dexamethasone can reduce type Ⅱ collagen and increase type I collagen in articular cartilage surface matrix, but the action mechanism of glucocorticoid to articular chondrocyte proliferation remains unclear. OBJECTIVE: To investigate the effects of dexamethasone sodium phosphate on rabbit articular chondrocytes cultured in vitro. DESIGN: Comparative observation.MATERIALS: New Zealand rabbits, 1 month old, were used for chondrocyte isolation and culture.METHODS: Rabbit articular chondrocytes cultured in vitro were randomly divided into control and experimental groups. Cells of the control group were cultured in DMEM media without dexamethasone sodium phosphate. Cells of experimental groups were cultured in DMEM media with different concentrations of dexamethasone sodium phosphate (0.02, 0.1, 0.5 g/L), respectively. MAIN OUTCOME MEASURES: Primary and passage chondrocytes were observed. Flow cytometry and immunocytochemistry were used to observe the effect of dexamethasone sodium phosphate on cell proliferation and type Ⅱ collagen synthesis. The ultrastructural changes of cultured chondrocytes were observed by transmission electron microscopy. RESULTS: The attachment and proliferation of experimental group chondrocytes was slower than control group. There average gray scale values of the experimental groups were significantly greater than the control group (P < 0.05). The cellular proportions of S phase and G_2+M phase of the experimental groups decreased but the cellular proportions of G0/G1 period increased. Under transmission electron microscope the amount of rough endoplasmic reticulum and mitochondria of the experimental groups decreased. CONCLUSION: Dexamethasone sodium phosphate inhibited articular chondrocyte proliferation, possibly due to the decrease of type Ⅱcollagen and protein synthesis ability of chondrocyte.
