Aim To investigate the mechanism of RhoA/ROCK signaling pathway in abnormal aortic contractility in type 2 diabetes (T2DM) mice. Methods The experiment was divided into two groups, the control group (db/m mice) and the model group (db/db mice). Changes of the response to different methods were measured in aorta rings using a Multi Myograph System. At the same time, the protein expression changes of aortic smooth muscle contraction signaling pathway in mice were determined by Western method. Results Compared with the control group, the blood glucose and body weight levels of the mice in the T2DM group significantly increased, and the cardiac function was abnormal (P <0. 01). The contractile response of the aorta of the diabetic mice induced by the contractile agents Phe, 5-HT and CaCl

Aim To observe whether the mechanosensitive ion channel Piezo1 was involved in the senescence of atrial fibroblasts by activating β-catenin based on our previous study which found marked increase of Piezo1 mRNA in senescent atrial fibroblasts. Methods Primary mouse atrial fibroblasts (MAFs) were isolated from male C57BL/6 mice (3-4 weeks) by enzyme digestion, and tert-butyl hydroperoxide (TBHP) was used to induce the senescence of cells. The ratio of senescent cells was detected by senescence-associated β-galactosidase (SA-β-Gal) staining. The protein levels of Piezo1, β-catenin/p-β-catenin, senescence-associated proteins p53 and p21 in the cells treated with TBHP (100 μmol · L

Aim To investigate the mechanism of Pi- ezol in the phenotypic changes of rat coronary arterial smooth muscle cells ( CASMCs) induced by high hydrostatic pressure.Methods CASMCs were isolated from Wistar rats and stimulated for 24 h at 0, 120 and 180 mmHg, respectively.The expressions of Piezol , contractile phenotvpe-related proteins including Cavl.2 ,SM-MHC ,cx-SMA and synthetic phenotvpe-re- lated proteins including OPN , MMP-2, Coll al were detected by Western blot.The effect of calcium influx mediated by Piezol was detected by Laser confocal mi- j j croscopy.CASMCs were treated with Piezol agonist Yodal , inhibitor GsMTx4 and Piezol-siHNA , respectively and the expressions of contractile phenotvpe and synthetic phenotvpe-related proteins were detected by Western blot.Results Compared with control ( 0 mmHg) , the expressions of Piezol , OPN, MMP-2 and Collal increased, but the expressions of Cavl.2,SM- MHC and cx-SMA decreased in 120 mmHg as well as 180 mmHg group.After stimulated by 180 mmHg high pressure, Piezol-mediated calcium influx was stronger than that in 0 mmHg group, hut decreased after Piezol knockdown.Treated with Yodal at 0 mmHg, the expression of contractile phenotvpe-related protein decreased while the expression of synthetic phenotvpe-re- lated protein increased compared with DMSO group..\Jfter using GsMTx4 to inhibit or siRNA to knockdown Piezol at 180 mmHg,the expression of contractile phe- notvpe-related protein increased and the expression of synthetic phenotype-related protein decreased compared with the control group.Conclusion Piezol promotes the transition from contractile phenotvpe to syn-thetic phenotvpe of CASMCs induced by high hydrostatic pressure.

Aim To investigate the role of calcium-independent phospholipase A2(iPLA2)in calcium regu-lation of intrarenal artery smooth muscle contraction.Methods The method of measuring the tension of isolated arterioles was used to explore the effect of bromoenol lactone(BEL), a specific inhibitor of iPLA2, on the tension of the intrarenal arteries in mice induced by different calcium channels, and the laser confocal calcium measurement technology was used to investigate the effect of BEL on the intracellular calcium influx mediated by arachidonic acid-mediated calcium channels.Results The intrarenal artery concentration dependent contractile response induced by the vasoconstrictors phenylephrine and 5-hydroxy tryptamine was inhibited by BEL(P<0.01).The contraction curve induced by CaCl2 was also inhibited by BEL(P<0.05).In the calcium-free K-H solution incubated with nifedipine, the intrarenal artery vasoconstriction caused by the release of sarcoplasmic reticulum calcium and the calcium influx of the SOC channel induced by CaCl2 was inhibited by BEL(P<0.05).BEL significantly inhibited the external calcium influx mediated by the ARC channel of human aortic smooth muscle cell lines incubated with nifedipine(P<0.01).Conclusions iPLA2 mediates the contractile response of intrarenal arteries by regulating the functions of L-type calcium channels, sarcoplasmic reticulum calcium release, SOC channels and ARC channels.

Aim To observe the effects of sacubitril/valsartan (Sac/Val, LCZ696) on atrial remodeling and atrial fibrillation (AF) susceptibility in spontaneously hypertensive rats (SHR). Methods Twenty-four 7-week-old male SHR were randomly divided into SHR group, SHR + Val group (30 mg · kg

Alzheimer's disease (AD) is characterized clinically as irreversible cognitive dysfunction. Although a significant progress has been made in the study of AD pathogenesis, the effective measures to block AD progress have not been satisfactory. Abnormal autophagy is thought to be involved in the pathogenesis of AD, and regulation of autophagy may become a new strategy for AD treatment. Some medicines, which regulate autophagy by mTOR-dependent and independent (Bcl-2/Beclin-1, GSK-3β, and p-AKT) pathways, have shown excellent effects in alleviating AD symptoms. In addition, certain compounds extracted from plants have also been reported to regulate autophagy and prevent AD progression through multiple pathways and multiple targets. This article reviews the recent advances in the regulation of autophagy and AD treatment. It provides a new theoretical basis for clinical treatment of AD.

To analyze the effectiveness and safety of intermittent lung inflation combined with rigid ureteroscopy in the treatment of upper ureteral stones that were not fully visible. The clinical and imaging data of 56 patients with upper ureteral stone undergoing rigid ureteroscopic lithotripsy combined with intermittent lung inflation in Zhejiang Quhua Hospital from March 2016 to October 2017 were retrospectively analyzed.Intermittentt lung inflation was used to change and stabilize the position of ureteral calculi during the operation,so as to ensure the visual field of ureteroscopy.Holmium laser lithotripsy was performed to remove the stones.Urinary tract abdominal plain X-ray or CT urography was performed 1 and 3 months after the operation to evaluate the residual stones and the clinical efficacy. Stones were successfully removed after a single attempt in 48 patients.In 5 patients,stones escaped into the kidney during ureteroscopic lithotripsy,and thus flexible ureteroscopy were performed.In 3 patients,a second session of auxiliary procedure was required,among whom 2 patients received extracorporeal shock wave lithotripsy and 1 patient underwent extracorporeal shock wave lithotripsy+ureteroscopic lithotripsy.The stone-free rates 1 and 3 months after surgery were 94.6%(53/56)and 100%(56/56),respectively.No severe complication such as ureter perforation,gross hematuria,septic shock,or pneumothorax occurred during and after surgery. Intermittent lung inflation in tracheal intubation under general anesthesia in patients with proximal ureteral stones that can not be fully visible during rigid ureteroscopic lithotripsy was feasible and reliable.It can effectively change the location of stones and thus enable safe and effective lithotripy.It expands the indications of rigid ureteroscopy for treating upper ureteral stones.

Life may have begun in an RNA world, which is supported by increasing evidence of the vital role that RNAs perform in biological systems. In the human genome, most genes actually do not encode proteins; they are noncoding RNA genes. The largest class of noncoding genes is known as long noncoding RNAs (lncRNAs), which are transcripts greater in length than 200 nucleotides, but with no protein-coding capacity. While some lncRNAs have been demonstrated to be key regulators of gene expression and 3D genome organization, most lncRNAs are still uncharacterized. We thus propose several data mining and machine learning approaches for the functional annotation of human lncRNAs by leveraging the vast amount of data from genetic and genomic studies. Recent results from our studies and those of other groups indicate that genomic data mining can give insights into lncRNA functions and provide valuable information for experimental studies of candidate lncRNAs associated with human disease.

Pulmonary infections are the most common complications in immunocompromised host (ICH).The immune system of ICH was in inhibitory condition because of long-term use of immunosuppressive agents,such as glucocorticoids,antimetabolite medicine and alkylating agents.Therefore,compared with the immunocompetent host,the condition is more critically serious in ICH with more difficult diagnosis and treatment,and higher motality after pulmonary infections.Early identification of pathogens and early treatment are helpful for improving the prognosis and decreasing mortality.
