    ABSTRACT: It has been demonstrated that most cells of the body respond to osmotic pressure in a systematic manner. The disruption of the collagen network in the early stages of osteoarthritis causes an increase in water content of cartilage which leads to a reduction of pericellular osmolality in chondrocytes distributed within the extracellular environment. It is therefore arguable that an insight into the mechanical properties of chondrocytes under varying osmotic pressure would provide a better understanding of chondrocyte mechanotransduction and potentially contribute to knowledge on cartilage degeneration. In this present study, the chondrocyte cells were exposed to solutions with different osmolality. Changes in their dimensions and mechanical properties were measured over time. Atomic force microscopy (AFM) was used to apply load at various strain-rates and the force–time curves were logged. The thin-layer elastic model was used to extract the elastic stiffness of chondrocytes at different strain-rates and at different solution osmolality. In addition, the porohyperelastic (PHE) model was used to investigate the strain-rate-dependent responses under the loading and osmotic pressure conditions. The results revealed that the hypo-osmotic external environment increased chondrocyte dimensions and reduced Young’s modulus of the cells at all strain-rates tested. In contrast, the hyper-osmotic external environment reduced dimensions and increased Young’s modulus. Moreover, using the PHE model coupled with inverse FEA simulation, we established that the hydraulic permeability of chondrocytes increased with decreasing extracellular osmolality which is consistent with previous work in the literature. This could be due to a higher intracellular fluid volume fraction with lower osmolality.

    ABSTRACT: The FMR1 gene, a member of the fragile X-related gene family, is responsible for fragile X syndrome (FXS). Missense single nucleotide polymorphisms (SNPs) are responsible for many complex diseases. The effect of FMR1 gene missense SNPs is unknown. The aim of this study, using in silico techniques, was to analyze all known missense mutations that can affect the functionality of the FMR1 gene, leading to mental retardation (MR) and FXS. Data on the human FMR1 gene were collected from the Ensembl database (release 81), National Centre for Biological Information dbSNP Short Genetic Variations database, 1000 Genomes Browser, and NHLBI Exome Sequencing Project Exome Variant Server. In silico analysis was then performed. One hundred-twenty different missense SNPs of the FMR1 gene were determined. Of these, 11.66% of the FMR1 gene missense SNPs were in highly conserved domains, and 83.33% were in domains with high variety. The results of the in silico prediction analysis showed that 31.66% of the FMR1 gene SNPs were disease related and that 50% of SNPs had a pathogenic effect. The results of the structural and functional analysis revealed that although the R138Q mutation did not seem to have a damaging effect on the protein, the G266E and I304N SNPs appeared to disturb the interaction between the domains and affect the function of the protein. This is the first study to analyze all missense SNPs of the FMR1 gene. The results indicate the applicability of a bioinformatics approach to FXS and other FMR1-related diseases. I think that the analysis of FMR1 gene missense SNPs using bioinformatics methods would help to diagnosis of FXS and other FMR1-related diseases.

    ABSTRACT: The field of tissue engineering is an emerging discipline which applies the basic principles of life sciences and engineering to repair and restore living tissues and organs. The purpose of this study was to investigate the effect of cold and non-thermal plasma surface modification of poly (ϵ-caprolactone) (PCL) scaffolds on fibroblast cell behavior. Nano-fiber PCL was fabricated through electrospinning technique, and some fibers were then treated by cold and non-thermal plasma. The cell–biomaterial interactions were studied by culturing the fibroblast cells on nano-fiber PCL. Scaffold biocompatibility test was assessed using an inverted microscope. The growth and proliferation of fibroblast cells on nano-fiber PCL were analyzed by MTT viability assay. Cellular attachment on the nano-fiber and their morphology were evaluated using scanning electron microscope. The result of cell culture showed that nano-fiber could support the cellular growth and proliferation by developing three-dimensional topography. The present study demonstrated that the nano-fiber surface modification with cold plasma sharply enhanced the fibroblast cell attachment. Thus, cold plasma surface modification greatly raised the bioactivity of scaffolds.

    ABSTRACT: Chronic obstructive pulmonary disease (COPD) is a disease with high prevalence and substantial associated economical burden. A significant determinant of quality of life, long-term survival, and health care costs is an acute exacerbation of COPD. Acute exacerbations are provoked by respiratory viruses, altered airway microbiome, and environmental factors. The current treatment options are limited. In order to develop specific therapeutic measures, it is important to understand how acute exacerbations evolve. This review focuses on pathophysiology of stable and exacerbated COPD.

    ABSTRACT: To study the hypoglycemic effect of composite rice flour, the diabetic mouse model was established through the intraperitoneal injection of alloxan saline (twice, 200 mg/kg bw). The mice were randomly divided into 4 groups: negative control, positive control, metformin medication group, and composite rice flour feed group. After 21 days, the fasting blood glucose levels were determined by glucose oxidase method and followed with a glucose tolerance test. The results show that the body weight growth rate of mice in the rice flour group was significantly higher than that of the medication group (P < 0.01). Comparing with the positive control group, the fasting blood glucose levels of medication group and rice flour group were significantly lower, and the glucose tolerance was significantly increased in rice flour group (P < 0.01). In conclusion, the composite rice flour has obvious hypoglycemic and protective effect for diabetic mouse model.

    ABSTRACT: Patients with hyperhomocysteinemia (HHcy), or elevated plasma homocysteine (Hcy), are at higher risk of developing arrhythmias and sudden cardiac death; however, the mechanisms are unknown. In this study, the effects of HHcy on sinus node function, atrioventricular conduction, and ventricular vulnerability were investigated by electrophysiological (EP) analysis, and the role of magnesium (Mg2+), an endogenous N-methyl-d-aspartate (NMDA) receptor antagonist, in attenuating EP changes due to HHcy was explored. Wild-type mice (WT) and mice receiving Hcy in the drinking water for 12 weeks (DW) were subjected to electrocardiographic and EP studies. DW compared to WT had significantly shorter RR, PR, QT, and HV intervals, corrected sinus node recovery times (CSNRT), Wenckebach periodicity (WP), atrioventricular nodal effective refractory periods (AVNERP), and right ventricular effective refractory periods (RVERP). To examine the role of Mg2+ in mitigating conduction changes in HHcy, WT, DW, and heterozygous cystathionine-β-synthase knockout mice (CBS+/−) were subjected to repeat EP studies before and after administration of low-dose magnesium sulfate (20 mg/kg). Mg2+ had no effect on EP variables in WT, but significantly slowed CSNRT, WP, and AVNERP in DW, as well as WP and AVNERP in CBS+/−. These findings suggest that ionic channels modulated by Mg2+ may contribute to HHcy-induced conduction abnormalities.

    ABSTRACT: Currently, as there is no systematic norm or standard for drug safety and inspection, it cannot be judged whether the regulatory authority or regulators have fulfilled their administrative responsibilities entirely or not, when a drug safety-related incident occurs. And there is a probability that some may even be wrongly punished. In this study, we have analyzed the risk of not having appropriate norms in place and also put forward recommendations for the government or the regulatory authorities to set up norms to be fulfilled for drug safety and inspection issues. This, on one hand, could provide a basic guideline for the regulatory authorities and regulators to improve their professional levels and administrative acumen and on the other hand, it could also provide a baseline for society to judge whether the regulatory authorities and regulators have fulfilled their responsibilities correctly and thereby also help prevent regulators from being mistakenly punished. This study proposes that a systematic and functional norm for drug safety and inspection could be set up relating to the determination of the responsibilities of regulatory authorities and scope of various inspections, number and frequency of inspections, number and qualifications of regulators, handling of inspection results, inspection records, and disciplinary codes for inspectors. This study also puts forward suggestions on who should be responsible for drafting the norms and what are the factors that need to be considered while formulating the norms.

    ABSTRACT: Bevacizumab can be potentially applied in filtration surgery in glaucoma patients. However, its mechanism remains unclear. In order to explore it, here, we established rat filtration surgery model and treat rat with Bevacizumab. At different time points after surgery, filtering blebs were collected and subjected to angiogenesis and inflammation genes analysis. Our results found that Bevacizumab significantly improved the outcome of filtration surgery and reduced complications (P < 0.05). Furthermore, angiogenesis factor, VEGF, and inflammation factors, TGFβ1 and TGFβ2, were dramatically inhibited by Bevacizumab treatment according to analysis of real-time PCR and western blot. Altogether, our findings suggested that Bevacizumab’s beneficial effects on filtration surgery were not limited to antiangiogenesis effect and anti-inflammation effects may be also involved.

    ABSTRACT: The aim of this study was to investigate the effect of axotomy and crush-related degeneration on the electrical activities of diaphragm muscle strips of experimental rats. In the present study, twenty-one male Wistar-albino rats were used and divided into three groups. The animals in the first group were not crushed or axotomized and served as controls. Phrenic nerves of the rats in the second and third groups were crushed or axotomized in the diaphragm muscle. Resting membrane potential (RMP) was decreased significantly in both crush and axotomy of diaphragm muscle strips of experimental rats (p < 0.05). Depolarization time (T DEP) and half-repolarization (1/2 RT) time were significantly prolonged in crush and axotomy rats (p < 0.05). Crushing or axotomizing the phrenic nerves may produce electrical activities in the diaphragm muscle of the rat by depolarization time and half-repolarization time prolonged in crush and axotomy rats.

    ABSTRACT: Studies describing the effects of leukemia inhibitory factor (LIF) on adipocyte differentiation in murine cells have shown varying results. For example, LIF has been reported to have a suppressive effect on adipocyte differentiation in the 3T3-L1 cell line, whereas it promoted adipocyte differentiation in the Ob1771 and 3T3-F442A cell lines. Thus, it is possible that the effects of LIF on adipogenesis vary with the developmental stage of the cells or tissues, but the details remain unclear. To further elucidate the role of LIF in adipogenesis, we investigated the effects of LIF on murine bone marrow stromal cells at the early and late stages of adipogenesis. LIF decreased the number of lipid foci and suppressed the expression levels of adipocyte differentiation markers at day 5; however, it enhanced these same traits at day 15. A previous report showed that the expression levels of Wnt signaling molecules are different at the early and late differentiation stages; therefore, we investigated the relationship between LIF and Wnt signaling. LIF affected the mRNA expression levels of different Wnt signaling molecules but inhibited the expression level of β-catenin protein at both days 5 and 15. Our data suggest that LIF has reciprocal roles during the early and late stages of adipocyte differentiation, regulating the Wnt signaling pathway.

    ABSTRACT: Our objective is to explore the tumor-specific mutated genes by transcriptome sequencing of patients with acute myeloblastic leukemia. 96 patients with subtype M2 acute myeloid leukemia (AML), admitted during January 2007 to January 2012, were selected. Bone marrow and peripheral blood samples from the patients after the first visit and the patients who were improved or alleviated, were subjected to high-throughput sequencing to compare the gene expression. The single nucleotide mutation related to subtype M2 AML was detected. Meanwhile, real-time fluorescent quantitation RT-PCR was used to detect the AML1/ETO fusion gene and its correlation with prognosis after treatment. Among 96 patients, AML1-ETO fusion gene was positive in 52 cases, the positive rate was 54.17 %. The complete relief (CR) rate of AML1-ETO fusion gene positive patients was 84.62 %, and the CR rate of AML1/ETO fusion gene negative patients was 77.27 %; the CR rate of AML1-ETO positive patients was higher than that of patients without the fusion gene, however there was no statistical difference. In the analysis of recurrent gene mutation in AML-M2 patients, IDH2, ASXL1, TET2, JAK1 and JAK2 gene expressions were not significantly different before treatment and after CR, however, IDHI, JAK3, ABL1 and BCR gene expressions were significantly different. In the study of transcriptome in AML-M2 patients, high-throughput sequencing could effectively detect the difference of the gene expression before treatment and after CR. Furthermore, positive expression of AML1-ETO fusion gene had effect on the prognosis of patients.
