Abstract
With advances in the fields of regenerative medicine, cell-free therapy has received increased attention. Exosomes have a variety of endogenous properties that provide stability for molecular transport across biological barriers to cells, as a form of cell-to-cell communication that regulates function and phenotype. In addition, exosomes are an important component of paracrine signaling in stem-cell-based therapy and can be used as a stand-alone therapy or as a drug delivery system. The remarkable potential of exosomes has paved the pathway for cell-free treatment in bone regeneration. Exosomes are enriched in distinct noncoding RNAs (ncRNAs), including microRNAs, long ncRNAs and circular RNAs. Different ncRNAs have multiple functions. Altered expression of ncRNA in exosomes is associated with the regenerative potential and development of various diseases, such as femoral head osteonecrosis, myocardial infarction, and cancer. Although there is increasing evidence that exosome-derived ncRNAs (exo-ncRNAs) have the potential for bone regeneration, the detailed mechanisms are not fully understood. Here, we review the biogenesis of exo-ncRNA and the effects of ncRNAs on angiogenesis and osteoblast- and osteoclast-related pathways in different diseases. However, there are still many unsolved problems and challenges in the clinical application of ncRNA; for instance, production, storage, targeted delivery and therapeutic potency assessment. Advancements in exo-ncRNA methods and design will promote the development of therapeutics, revolutionizing the present landscape.

Abstract
AimsLiuzijue Qigong (LQG) exercise is a traditional Chinese exercise method in which breathing and pronunciation are combined with movement guidance. Breathing is closely related to balance, and LQG, as a special breathing exercise, can be applied to balance dysfunction after stroke. The purpose of this study was to observe the clinical effects of short-term LQG exercise on balance function in patients recovering from stroke.MethodsStroke patients were randomly divided into an Intervention Group (IG) (n = 80) and a Control Group (CG) (n = 80). The IG received conventional rehabilitation training plus LQG and the CG received conventional rehabilitation training plus Core Stability Training (CST). All patients received treatment once a day, 5 times a week for 2 weeks. The primary outcome was Berg Balance Scale (BBS). Secondary outcome measures were static standing and sitting balance with eyes open and closed, Fugl-Meyer Assessment (FMA), Maximum Phonation Time (MPT), Modified Barthel Index (MBI) and diaphragm thickness and mobility during quiet breath (QB) and deep breath (DB).ResultsCompared with the CG, the IG showed significant improvement in the BBS (10.55 ± 3.78 vs. 9.06 ± 4.50, P = 0.039), MPT (5.41 ± 4.70 vs. 5.89 ± 5.24, P = 0.001), MBI (12.88 ± 6.45 vs. 10.00 ± 4.84, P = 0.003), diaphragmatic mobility during QB (0.54 ± 0.73 vs. 0.33 ± 0.40, P = 0.01) and diaphragmatic mobility during DB (0.99 ± 1.32 vs. 0.52 ± 0.77, P = 0.003), Cop trajectory in the standing position with eyes open (−108.34 ± 108.60 vs. −89.00 ± 140.11, P = 0.034) and Cop area in the standing positions with eyes open (−143.79 ± 431.55 vs. −93.29 ± 223.15, P = 0.015), Cop trajectory in the seating position with eyes open (−19.95 ± 23.35 vs. −12.83 ± 26.64, P = 0.001) and Cop area in the seating position with eyes open (−15.83 ± 9.61 vs. −11.29 ± 9.17, P = 0.002).ConclusionsThe short-term LQG combined with conventional rehabilitation training significantly improved the balance functions of stroke patients. It also improved static standing and sitting balance with the eyes open, diaphragm functions, maximum phonation time and the quality of daily life for stroke patients.Clinical Trial Registrationhttp://www.chictr.org.cn/edit.aspx?pid=25313&htm=4, Identifier: ChiCTR1800014864.

Abstract
Cadmium, a toxic heavy metal, seriously affects human health and ecological security. The cation/H+ exchanger (CAX) family is a unique metal transporter that plays a crucial role in Cd acquisition, transfer, and remission in plants. Although there are many studies related to the genome-wide analysis of Populus trichocarpa, little research has been done on the CAX family genes, especially concerning Cd stress. In this study, genome-wide analysis of the Populus CAX family identified seven stress-related CAX genes. The evolutionary tree indicated that the CaCA family genes were grouped into four clusters. Moreover, seven pairs of genes were derived by segmental duplication in poplars. Cis-acting element analysis identified numerous stress-related elements in the promoters of diverse PtrCAXs. Furthermore, some PtrCAXs were up-regulated by drought, beetle, and mechanical damage, indicating their possible function in regulating stress response. Under cadmium stress, all CAX genes in the roots were up-regulated. Our findings suggest that plants may regulate their response to Cd stress through the TF-CAXs module. Comprehensively investigating the CAX family provides a scientific basis for the phytoremediation of heavy metal pollution by Populus.

Abstract
When a fluid system is subject to strong rotation, centrifugal fluid motion is expected, i.e., denser (lighter) fluid moves outward (inward) from (toward) the axis of rotation. Here we demonstrate, both experimentally and numerically, the existence of an unexpected outward motion of warm and lighter vortices in rotating thermal convection. This anomalous vortex motion occurs under rapid rotations when the centrifugal buoyancy is sufficiently strong to induce a symmetry-breaking in the vorticity field, i.e., the vorticity of the cold anticyclones overrides that of the warm cyclones. We show that through hydrodynamic interactions the densely distributed vortices can self-aggregate into coherent clusters and exhibit collective motion in this flow regime. Interestingly, the correlation of the vortex velocity fluctuations within a cluster is scale-free, with the correlation length being proportional ( ≈ 30%) to the cluster length. Such long-range correlation leads to the counterintuitive collective outward motion of warm vortices. Our study brings insights into the vortex dynamics that are widely present in nature. Ding et al. study the collective motion of densely packed vortices in rotating thermal convection. They uncover the counterintuitive effect of warmer and thus lighter vortices moving outward from the central axis of rotation, driven by long range, scale-free vortex correlations.

Abstract
The present study was performed in order to investigate the safety and efficacy of different vasoactive drugs combined with enteral nutrition in terms of treating elderly patients with sepsis. A total of 75 elderly patients with sepsis treated with enteral nutrition in our hospital were randomly divided into three groups: group A (n = 25), group B (n = 25) and group C (n = 25). The three groups were treated with dopamine, dobutamine and norepinephrine respectively. One week after treatment, the therapeutic effects of the three groups were compared, the vascular elastic indexes, hemodynamic indexes and levels of inflammatory factors of the three groups were measured. After treatment, the clinical effective rate of group C was evidently higher than that of group A and group B. The vascular elasticity coefficient and stiffness coefficient in group C were significantly lower than those in group A and group B, and the arterial compliance in group C was significantly higher than that in group A and group B (P < 0.05). The levels of MAP and PVRI in group C were significantly higher than those in group A and B, and the levels of CI, CVP and HR in group C were significantly lower than those in group A and group B (P < 0.05). Norepinephrine elicited greater effects in terms of improving hemodynamic indexes, vascular elasticity and reducing the level of inflammatory factors compared with dopamine and dobutamine in elderly patients harboring sepsis.

Abstract
Brownian motion of particles in fluid is the most common form of collective behavior in physical and biological systems. Here, we demonstrate through both experiment and numerical simulation that the movement of vortices in a rotating turbulent convective flow resembles that of inertial Brownian particles, i.e., they initially move ballistically and then diffusively after certain critical time. Moreover, the transition from ballistic to diffusive behaviors is direct, as predicted by Langevin, without first going through the hydrodynamic memory regime. The transitional timescale and the diffusivity of the vortices can be collapsed excellently onto a master curve for all explored parameters. In the spatial domain, however, the vortices exhibit organized structures, as if they are performing tethered random motion. Our results imply that the convective vortices have inertia-induced memory such that their short-term movement can be predicted and their motion can be well described in the framework of Brownian motions.

Abstract
Background In this study, ubiquitin-specific peptidase 22 (USP22) was detected in both thyroid papillary cancer-1 (TPC-1) and normal thyroid epithelial cell lines (HT-ori3), and its biological function was analyzed. Method Cell culture, resuscitation, and passage, Western blot, and real-time polymerase chain reaction were used. Results The expression of USP22 was found to be significantly higher in TPC-1 cancer cells than in normal cells. After silencing of the USP22 gene in TPC-1 cells, the levels of USP22 gene and protein expression were significantly decreased. After 6 h with silencing of the USP22 gene, the migration rate was lower and the cells had become smaller than in the control group (P<0.05). At 24 h, the number of invasive cells was significantly lower than in the control group (P<0.05). A cell viability test showed that the differences between the groups increased on days 4 and 5 (P<0.05). The number of colony-forming cells had also decreased significantly after 10 days (P<0.05) in the USP22-siRNA1 group. Compared with the control group, the protein levels of USP22, cyclin D2, and Bmi-1 were significantly decreased (P<0.05). The decrease of USP22 was positively correlated with the decrease of Bmi-1 and cyclin D2. After silencing of the USP22 gene in normal HT-ori3 cells, the USP22 gene and protein expressions decreased significantly (P<0.05). A cell viability test showed that the difference had increased (P<0.01), and the number of cloned cells had significantly decreased than that in negative group (P<0.01). Conclusions In conclusion, the USP22 gene plays a key role in the growth, proliferation, invasion, and migration of papillary thyroid cancer cells. USP22 possibly exerts its effect in TPC through the Bmi-1 and cyclin D2 pathways. USP22 also plays a crucial role in the growth of normal thyroid cells.

Abstract
Purpose Phosphoinositide 3-kinase (PI3K) and the downstream Akt/mammalian target of rapamycin (mTOR) pathway are central to the control of cell proliferation and survival. Although abnormal activation of this pathway has been well established in a variety of tumours, limited studies are available on synovial sarcoma. The aim of this study was to investigate the expression of several key proteins of those pathways in synovial sarcomas and to correlate the expression of these proteins with clinicopathologic features and prognosis. Patients and Methods A total of 174 patients with synovial sarcomas were recruited for this study. The phosphorylation status of Akt, mTOR, and eukaryotic translation initiation factor 4E binding protein (4E-BP1) was measured by immunohistochemistry assays in formalin-fixed, paraffin-embedded samples. Correlations between the expression levels of these proteins and clinicopathologic features and prognosis were analysed. Results The positive rates of phosphorylated (p)Akt, pmTOR, p4E-BP1, and CyclinD1 were 62.7%, 55.6%, 47.1%, and 52.6%, respectively. The positive results of pmTOR, pAkt, and downstream p4E-BP1 were correlated with each other. The positive pAkt, pmTOR, p4E-BP1, and CyclinD1 results were more highly expressed in head and neck and visceral tumours, and positive p4E-BP1 results were correlated with larger size and larger areas of necrosis. In multivariate analysis of clinicopathologic factors, head and neck and visceral location, large tumour size, larger areas of necrosis and frequent mitosis were confirmed as risk factors for shorter overall survival. Positive pAkt, pmTOR and p4E-BP1 results were correlated significantly with shorter overall survival, and CyclinD1 was not in the univariate analysis. The positive pmTOR, pAkt, p4E-BP1, and CyclinD1 results were significantly poor prognostic factors for overall survival, and only positive p4E-BP1 results were significantly associated with shorter event-free survival in multivariate analysis. Conclusion This study demonstrated the high expression of pAkt, pmTOR, and p4E-BP1 associated with aggressive clinical behaviour in synovial sarcomas and provided evidence for prognostic evaluation and targeted therapy.

Abstract
OBJECTIVE Forkhead box Q1 (FOXQ1), a member of the forkhead transcription factor family, plays important parts in cell cycle, apoptosis, metabolism, immunology and tumour genesis. Its expression has been associated with poor clinical prognosis in various tumours. However, the clinical significance of FOXQ1 in papillary thyroid carcinoma (PTC) has not been fully studied. The purpose of this study was to investigate whether FOXQ1 is correlated with poor prognosis in PTC. DESIGN/METHODS We performed a retrospective study of 136 PTCs. Immunohistochemistry (IHC) was used to examine the expression of FOXQ1 in 136 PTCs and 47 nodular goitre specimens. Rank-sum test, chi-square test, Kaplan-Meier survival analysis, univariate and multivariate Cox analyses were used to investigate the clinical and prognostic significance of FOXQ1 expression in PTC. RESULTS The comparison of PTC specimens with nodular goitre with papillary hyperplasia specimens revealed an upregulation of FOXQ1 in PTC. Overexpression of FOXQ1 was observed in 63.24% of PTC and correlated with classic variant, tall variant, distant metastasis, AJCC stage and recurrence. FOXQ1-positive expression was associated with shorter disease-free survival: median disease-free survival of FOXQ1-positive patients was 23 months compared with 128 months for FOXQ1-negative patients (Log-rank χ2 = 12.31, P = 0.00045). Additional independent risk factors in this study were multifocality (recurrence-free survival [RFS]: hazard ratio [HR] = 2.391, P < 0.05), extrathyroidal extension (RFS: HR = 3.906, P < 0.05) and positive expression of FOXQ1 (RFS: HR = 6.385, P < 0.01). CONCLUSIONS Our results indicated that FOXQ1 may be a useful additional biomarker to evaluate the progression of PTC and to predict likely relapse of disease.

Abstract
Nitinol alloy occluders are widely used in the transcatheter intervention treatment of congenital heart diseases like patent ductus arteriosus (PDA). However, nitinol alloy contains high levels of nickel, which can lead to toxic effects in the immune and hematopoietic systems if released in sufficient quantities. A new type of single-rivet occluder coated with nano-film has been developed to limit the release of nickel. In total, 23 patients were recruited and randomly assigned to the experimental group (n=12) with the new nano-film single-rivet occluders or the control group (n=11) with the traditional occluders. One case in the control group was lost to follow-up. The remaining 22 cases were followed up at 24 h, 7 days, 1 month, 3 months, and 6 months after the procedure. There were no statistically significant differences in routine blood test, alanine aminotransferase, creatinine, and troponin between the experimental and control groups. Serum nickel concentration in both two groups increased at 24 h after the procedure, peaked at 1 month, and returned to preoperative levels at 6 months. Serum nickel levels in the experimental group were significantly lower than in the control group at 24 h, 7 days, 1 month, and 3 months after the procedure. These data suggested that the nano-film coating effectively prevented nickel release from the new occluders, and therefore has a preferable safety profile.

Abstract
PURPOSE This study aimed to evaluate the efficacy and safety of bevacizumab in the treatment of recurrent ovarian cancer. METHODS The Cochrane Library, MEDLINE, and EMBASE were searched. Data regarding the use of bevacizumab in recurrent ovarian cancer were collected from randomized controlled trials (RCTs). Data were evaluated with the Cochrane systematic method, and statistical analysis was performed with the RevMan 5.2 software. Two RCTs comprising a total of 845 patients were included. RESULTS Bevacizumab combined with conventional chemotherapy prolonged the progression-free survival (PFS) (hazard ratio [HR] 0.48; 95% confidence interval [CI], 0.41-0.56), without significantly altering the overall survival (OS) (HR 1.03; 95% CI 0.79-1.33). Adverse events (NCI-CTCAE v.4.0) associated with bevacizumab were ≥ grade 3 hypertension (relative risk [RR] 2.30; 95% CI 1.39-3.83) and bleeding (RR 4.76; 95% CI 1.38-16.37). CONCLUSIONS Bevacizumab prolonged the PFS of patients with recurrent ovarian cancer. Additional high-quality randomized controlled trials are needed to verify these results.

Abstract
As a nonspecific physical stimulation, the effect of acupuncture on diseases is produced by motivating the inherent regulatory system in the body, having the characteristics of whole regulation, dual directional regulation, etc. Modern scientific researches show that body's inherent regulatory system is neuro-endocrine-immune (NEI) network. Hence, we speculate that the regulatory effect of acupuncture may be produced through its regulation of NEI network. In this article, we reviewed the recent researches about acupuncture's effect on the NEI network, to find out the evidence of acupuncture adjusting NEI network and provide some evidences for revealing the mechanism of acupuncture.

Abstract
Congestive heart failure (CHF) is commonly associated with renal dysfunction. The goal of the current study was to evaluate the role of endothelin in the renal dysfunction of experimental CHF by using tezosentan, a potent dual endothelin receptor antagonist. Rats were subjected to coronary artery ligation. Cardiac and renal hemodynamics were assessed after 3-5 weeks, when CHF had developed. Compared with control rats, CHF rats had significantly higher left ventricular end-diastolic pressure (LVEDP), lower mean arterial pressure, and reduced dP/dt(max). CHF rats had severe renal vasoconstriction, as assessed by increased renal vascular resistance (RVR, p < 0.001), decreased renal plasma flow (RPF, p < 0.001), and glomerular filtration rate (GFR, p < 0.001). Filtration fraction rose (p < 0.001). Urine flow rate and sodium excretion were markedly lower. Acute administration of tezosentan induced a marked decrease in LVEDP without change of dP/dt(max) and heart rate. Tezosentan decreased RVR (-43%, p < 0.001) and increased RPF and GFR. Filtration fraction decreased slightly. Tezosentan also increased urine flow rate and sodium excretion. These findings demonstrate that endothelin at least partly mediates the altered renal hemodynamics associated with experimental CHF. Dual endothelin receptor blockade could be useful for the improvement of both cardiac and renal function in CHF.
