Inhibition of ginsenoside Rb 1 on the epithelial-mesenchymal transition of renal tubular epithelial cells by regulating TGF-β1/Smad3 signaling pathway / 中国药房

OBJECTIVE To study the effects of ginsenoside Rb 1（G-Rb1）on epithelial-mesenchymal transition （EMT）of renal tubular epithelial cells and its potential mechanism. METHODS The growth factor β1（TGF-β1）10 ng/mL was used to induce EMT of human renal tubular epithelial cells HK- 2. The morphological changes of HK- 2 cells were observed after treated with 10， 20，30 μmol/L G-Rb1 for 48 h. The transcriptional activities of biovector SBE in human embryonic kidney cell HEK 293 were determined after 24 h treatment with 1.0，2.5，5.0，10，20，30 μmol/L G-Rb1. Effects of above concentration of G-Rb 1 on the viability of HK- 2 cells were determined after 24 h of treatment. mRNA expressions of α-smooth muscle actin （α-SMA），collagen Ⅰ （COL-Ⅰ）and fibronectin （FN）in HK- 2 cells were detected after treated with 10，20，30 μmol/L G-Rb1 for 24 h. The expressions of α-SMA，Smad3，p-Smad3，COL-Ⅰ，FN and E-cadherin were detected after treated with 10，20，30 μmol/L G-Rb1 for 24 h. RESULTS G-Rb1 of 10-30 μmol/L significantly inhibited TGF-β1-induced EMT in HK- 2 cells and the increase of transcriptional activities of biovector SBE induced by TGF-β1（P＜0.05），but had no effects on relative activities of HK- 2 cells（P＞0.05）. The protein and mRNA expressions of α-SMA，COL-Ⅰ and FN ， the protein expressions of Smad 3 and p-Smad 3 were significantly up-regulated induced by TGF-β1（P＜0.05），while the protein expression of E-cadherin was significantly down- regulated（P＜0.05）；G-Rb1 could effectively reverse aboveprotein or mRNA expressions. CONCLUSIONS G-Rb1 can protect renal tubular epithelial cells from EMT induced byxiezhishen TGF-β1 to a certain extent ，which may be related to inhibiting the activation of TGF-β1/Smad3 signaling pathway.

Quantitative analysis of breathing patterns based on wearable systems / 生物医学工程学杂志

Breathing pattern parameters refer to the characteristic pattern parameters of respiratory movements, including the breathing amplitude and cycle, chest and abdomen contribution, coordination, etc. It is of great importance to analyze the breathing pattern parameters quantificationally when exploring the pathophysiological variations of breathing and providing instructions on pulmonary rehabilitation training. Our study provided detailed method to quantify breathing pattern parameters including respiratory rate, inspiratory time, expiratory time, inspiratory time proportion, tidal volume, chest respiratory contribution ratio, thoracoabdominal phase difference and peak inspiratory flow. We also brought in "respiratory signal quality index" to deal with the quality evaluation and quantification analysis of long-term thoracic-abdominal respiratory movement signal recorded, and proposed the way of analyzing the variance of breathing pattern parameters. On this basis, we collected chest and abdomen respiratory movement signals in 23 chronic obstructive pulmonary disease (COPD) patients and 22 normal pulmonary function subjects under spontaneous state in a 15 minute-interval using portable cardio-pulmonary monitoring system. We then quantified subjects' breathing pattern parameters and variability. The results showed great difference between the COPD patients and the controls in terms of respiratory rate, inspiratory time, expiratory time, thoracoabdominal phase difference and peak inspiratory flow. COPD patients also showed greater variance of breathing pattern parameters than the controls, and unsynchronized thoracic-abdominal movements were even observed among several patients. Therefore, the quantification and analyzing method of breathing pattern parameters based on the portable cardiopulmonary parameters monitoring system might assist the diagnosis and assessment of respiratory system diseases and hopefully provide new parameters and indexes for monitoring the physical status of patients with cardiopulmonary disease.

Experimental study of inhibition of tumor cell proliferation by a novel gene SPATA12 / 中南大学学报(医学版)

OBJECTIVE@#To explore the inhibitory role of spermatogenesis-associated gene 12 (SPATA12) on tumor cell proliferation and its possible mechanism.@*METHODS@#The expression pattern of SPATA12 in testicular tumors was investigated by in situ hybridization analysis using tissue microarrays. The effects of SPATA12 on tumor cell proliferation and colony formation was detected by 3-(4.5-dimethylthiazol-2- yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and colonyforming assays, respectively. The changes of expression level of cell cycle genes in tumor cells were detected by reverse transcription polymerase chain reaction(RTPCR).@*RESULTS@#In situ hybridization analysis showed that the SPATA12 was highly expressed in normal adult testis, but lacking in testicular tumors such as seminoma. MTT assay and colony-forming assay indicated that the exogenous expression of SPATA12 could suppress both tumor cell proliferation and colony formation. RT-PCR showed that the expression of cyclin A1 gene was markedly suppressed and the level of cyclin D1 was somewhat reduced following SPATA12 transfection. However, no obvious changes were observed in mRNA expression of cyclin B1 or cyclin E1 after SPATA12 transfection.@*CONCLUSION@#SPATA12 could be an inhibitor during the development of tumor via regulation of cell cycle genes.

The predicting effects of ACE gene and PAI-I gene polymorphisms on CCA-IMT progression in newly diagnosed T2DM / 中国医师杂志

Objective The study was to investigate the relationship among angiotensin 1-converting enzyme(ACE), plasminogen activator inhibitor-1 (PAI-1)gene polymorphisms and the common carotid artery (CCA-IMT), and the predicting effects of them on CCA-IMT in newly diagnosed type 2 diabetes (T2DM). Methods The polymorphisms of ACE (I/D) gene and PAI-I (4G/5G) gene were deter-mined by polymemse chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific polymerase chain reaction (AS-PCR) method in 308 cases with T2DM. CCA-IMT was compared among the groups with different genotypes of ACE and PAI-1. The in-dependent or synergistic effects of the ACE I/D and PAI-1 40/5G polymorphisms on CCA-IMT in 308 patients with T2DM were analyzed with multivariate linear regression. Then the 156 newly diagnosed type 2 diabetics (durations< I year) without AS received the maltifactorial targeted intervention, including taking aspirin and controlling blood glucose, blood pressure, blood lipid and body weight. The differences of metabolic control, ACE (I/D) and PAId (40/5G) gene polymorphisms were analyzed. Logistic regression analysis was used to analyze the eorrelation among the CCA-IMT, ACE (I/D) and PAI-1 (4G/5G) polymorphisms. Results Patients with ACE DD genotypes had higher CCA-IMT than those with ACE-Ⅱ or ACE ID genotypes. Patients with both ACE DD and PAI-1 404G genotypes had a higher CCA-IMT than those with any other pairs of genotypes. Multivariate linear regression analysis showed that ACE DD and PAI-1 4G4G gene polymorphisms had synergistic effect on the CCA-IMT in T2DM patients. After 2 years multifactorial intervention, the frequencies of PAI-1 4G alleles and 404G genotypas were lower than those in the CCA-IMT non-inereasing group. Conclusions These findings indicate that the ACE-DD geno-type and its synergistic effects with the PAI-1 4G/4G genotype are independent risk factors for the CCA-IMT in T2DM patients. Under multi-factorial intervention for 2 years, PAI-1 4G/4G genotype may be a negative predictor for the progression of CCA-IMT in T2DM patients.

Cell traction forces measurement based on BioMEMS microposts matrix / 医用生物力学

A review of cell traction forces (CTFs) measurement based on Biological MiCro Electromechanical Systems (BioMEMS) microposts matrix is presented.CTFs are exerted by cells and ansmitted to the underly-ing substrate through focal adhesions and close contacts.which is essential for cells movement.Cells probe the mechanicaI compliance of the exlracellular mabix (ECM) in part by locally deforming it with nanonewton-scale traction forces.Precision measurement of CTFs is significant for many researches such as call biology and tissue engineering and so on.Enabled by the advancement in BioMEMS technology,surface treated high aspeect ratio Polydimethyisiloxane(PDMS)micropos matrix devices,which serve as BioMEMS sensom for de-tecting cellular nanoforces and studying in vitro cell mechanics,have been developed.Closely spaced vartical microposts matrixes were designed to encourage cells to attach and spread across multiple microposts,and to bend the microposts like vertical cantilevers as the cells locomote on the surface.Using this dense and dis-crete matrix of microposts rather than a convanfional continuous substrate,CTFs can be directly measured and quantified by processing the microscopy images of the deformations of microposts.The resolution of the force was in tens of nN/μm scale.At first,the conventional CTFs measurement methods were concisely summa-rized.Then BioMEMS microposts matrix method was described in detail,including principle and fabfication process,Surface treatment and cell expedment results.Furthermore,high aspect ratio structure collapse prob-lem was investigated.
