Abstract
Background Better therapeutic drugs are required for treating hypertensive diabetic nephropathy. In our previous study, the Huaju Xiaoji (HJXJ) formula promoted the renal function of patients with diabetes and hypertensive nephropathy. In this study, we investigated the therapeutic effect and regulation mechanism of HJXJ in hypertensive diabetic mice with nephropathy. Methods We constructed a mouse hypertensive diabetic nephropathy (HDN) model by treating mice with streptozotocin (STZ) and nomega-nitro-L-arginine methyl ester (LNAME). We also constructed a human glomerular mesangial cell (HGMC) model that was induced by high doses of sugar (30 mmol/mL) and TGFβ1 (5 ng/mL). Pathological changes were evaluated by hematoxylin and eosin (H&E) staining, periodic acid Schiff (PAS) staining, and Masson staining. The fibrosis-related molecules (TGFβ1, fibronectin, laminin, COL I, COL IV, α-SMA, and p-smad2/3) were detected by enzyme-linked immunosorbent assay (ELISA). The mRNA levels and protein expression of endoplasmic reticulum stress, fibrosis molecules, and their downstream molecules were assessed using qPCR and Western blotting assays. Results Administering HJXJ promoted the renal function of HDN mice. HJXJ reduced the expression of ER stress makers (CHOP and GRP78) and lncMGC, miR379, miR494, miR495, miR377, CUGBP2, CPEB4, EDEM3, and ATF3 in HDN mice and model HGMCs. The positive control drugs (dapagliflozin and valsartan) also showed similar effects after treatment with HJXJ. Additionally, in model HGMCs, the overexpression of CHOP or lncMGC decreased the effects of HJXJ-M on the level of fibrosis molecules and downstream target molecules. Conclusion In this study, we showed that the HJXJ formula may regulate ERS-lncMGC/miRNA to enhance renal function in hypertensive diabetic mice with nephropathy. This study may act as a reference for further investigating whether combining HJXJ with other drugs can enhance its therapeutic effect. The findings of this study might provide new insights into the clinical treatment of hypertensive diabetic nephropathy with HJXJ.

Abstract
Without any additives and photocatalysts, the visible-light-promoted radical cascade reaction between alkynoates and phenyl disulfides has been developed at room temperature. Through S-S bond photolysis and homolytic cleavage, addition of a sulfur radical, aryl migration, decarboxylation, and H atom abstraction, the cascade reaction provides an efficient and practical route to trisubstituted 1,1-diarylvinylsulfides with a wide scope of substrates and good to excellent yields.

Abstract
Chromothripsis, the process of catastrophic shattering and haphazard repair of chromosomes, is a common event in cancer. Whether chromothripsis might constitute an actionable molecular event amenable to therapeutic targeting remains an open question. We describe recurrent chromothripsis of chromosome 21 in a subset of patients in blast phase of a myeloproliferative neoplasm (BP-MPN), which alongside other structural variants leads to amplification of a region of chromosome 21 in ∼25% of patients ('chr21amp'). We report that chr21amp BP-MPN has a particularly aggressive and treatment-resistant phenotype. The chr21amp event is highly clonal and present throughout the hematopoietic hierarchy. DYRK1A , a serine threonine kinase and transcription factor, is the only gene in the 2.7Mb minimally amplified region which showed both increased expression and chromatin accessibility compared to non-chr21amp BP-MPN controls. We demonstrate that DYRK1A is a central node at the nexus of multiple cellular functions critical for BP-MPN development, including DNA repair, STAT signalling and BCL2 overexpression. DYRK1A is essential for BP-MPN cell proliferation in vitro and in vivo , and DYRK1A inhibition synergises with BCL2 targeting to induce BP-MPN cell apoptosis. Collectively, these findings define the chr21amp event as a prognostic biomarker in BP-MPN and link chromothripsis to a druggable target.

Abstract
PURPOSE/OBJECTIVE(S) Methionine is an amino acid necessary for numerous processes critical for cell growth and survival. While normal cells can tolerate methionine deficiency, most cancer cells are methionine auxotrophs, requiring dietary intake since they cannot synthesize it. In vitro, methionine deficiency causes cancer cells to undergo cell cycle arrest and cell death, and in vivo a methionine restricted diet (MRD) enhances radiosensitization without significant adverse effects. Combining a MRD and radiation therapy (RT) to treat human malignancies has never been evaluated. The hypothesis of this Phase I study was that a MRD would be safe, and feasible to administer concurrently with curative-intent RT. MATERIALS/METHODS Eligible patients included adults with any non-skin cancer malignancy undergoing standard radiation therapy without concurrent cytotoxic chemotherapy. The MRD consisted of low-protein cereals, grains, and breads; fruits; vegetables; margarines and oils; and simple carbohydrates. A clinical dietician developed a personalized meal plan with each subject to reduce methionine consumption to 5-10 mg/kg body weight/day, while maintaining adequate protein and caloric intake. An unlimited supply of a commercially available methionine-free protein supplement was provided to minimize hunger and weight loss. The MRD extended from 2 weeks before initiation of RT, through 2 weeks beyond completion of RT. The primary endpoint for safety was the rate of grade 3 or higher acute and late toxicities per CTCAE, over 12 months follow-up. Feasibility was assessed with a biweekly quantitative plasma amino acid panel during the MRD. The target accrual was 15 subjects. RESULTS Over two years, 53 patients were offered enrollment, 9 subjects enrolled, 5 completed the MRD and RT, and 4 withdrew during the MRD. The table summarizes subjects' characteristics and outcomes. There was no grade 3 or higher adverse events attributable to the MRD. Methionine plasma levels varied over the course of treatment, and while no subject achieved the target of 13 μM, two nadired at 14 μM. The trial was closed early due to slow accrual and subjects' difficulty maintaining the diet. CONCLUSION This study suggests a MRD is safe with thoracic or abdominopelvic RT, with toxicities comparable to those expected with RT alone. However, the diet was challenging, and unacceptable to most patients with cancer.

Abstract
Rhododendron is well-known for its beauty and colorful corolla. Although some high-quality whole-genome sequencing of Rhododendron has been completed, there is lack of studies on long terminal repeat (LTR) retrotransposons in Rhododendron, which limits our ability to elucidate the causes of genetic variations in Rhododendron species. The properties of the intact Rhododendron LTR retrotransposon were investigated at the genome-wide level. Based on the available data, the high-quality genomes from five species, i.e., R. griersonianum, R. simsii, R. henanense subsp. lingbaoense, R. mucronatum var. ripense and R. ovatum were selected as the identification targets with good assembly continuity. A total of 17,936 intact LTR retrotransposons were identified; they belong to the superfamilies Copia and Gypsy with 17 clades. The insertion time of these transposons was later than 120 million years ago, and the outbreak period was concentrated more recently than 30 million years ago. Phylogenetic analysis revealed that many LTR retrotransposons might originate from intraspecific duplication. The current evidences also suggests that most of the LTR retrotransposons were inserted in the interstitial part of the genes in R. griersonianum, R. simsii, R. henanense, and R. ovatum, and the functions of the inserted genes are mainly involved in starch metabolism and proteolysis etc. The effect of LTR retrotransposon on gene expression depends on its insertion site and activation. Highly expressed LTR retrotransposons tended to be younger. The activity of LTR retrotransposons may affect some stage-specific expression genes of flower development, such as leucine-rich repeat receptor-like kinase. The available results herein improve our knowledge of LTR retrotransposons in Rhododendron genomes and facilitate the further study of genetic variation and trait evolution in Rhododendron.

Abstract
Cognitive impairment is a symptom of neurological disorders, including dementia and Alzheimer's disease; and mild cognitive impairment can be a precursor of both disorders. Aged humans and animal models with other systemic disorders, such as cardiovascular diseases and diabetes, display a higher incidence of cognitive decline. Epidemiological studies have shown that the incidence of cognitive impairment also is higher in subjects with certain inflammatory skin disorders, including psoriasis and chronic eczematous dermatitis. Chronologically aged individuals exhibit increased cutaneous inflammation and elevated circulating cytokine levels, linked to alterations in epidermal function, which itself can induce cutaneous inflammation. Conversely, strategies that improve epidermal function can lower cytokine levels in both the skin and circulation. Thus, it seems likely that epidermal dysfunction could contribute, at least in part, to the development of chronic low-grade inflammation, also termed 'inflammaging', in the elderly. The evidence of cognitive impairment in patients with inflammatory dermatoses suggests a link between cutaneous inflammation and cognitive impairment. Because of the pathogenic role of epidermal dysfunction in ageing-associated cutaneous inflammation, improvements in epidermal function could be an alternative approach for mitigation of the ageing-associated decline in cognitive function.

Abstract
Homeodomain-leucine zipper (HD-Zip) proteins are plant-specific transcription factors that play important roles in different biological processes, especially leaf development. However, no studies to date have identified the HD-Zip genes in Liriodendron chinense nor characterized their functions. We identified the HD-Zip genes in L. chinense by analysing the phylogeny, chromosome location, structure, conserved motif, cis-regulatory elements, synteny, post-transcriptional regulation and expression patterns of these genes during leaf development. A total of 36 LcHD-Zip genes were identified and divided into four subfamilies (HD-Zip I to IV). Synteny analysis revealed that segmental duplication was the main force driving the expansion of LcHD-Zip genes. These 36 LcHD-Zip genes exhibited 11 different expression patterns. Pattern 1, 2, 3, 4, 6, 7, 8 and 9 genes may play important roles in leaf development, such as leaf initiation, leaf polarity establishment, leaf shape development, phytohormone-mediated leaf growth and leaf epidermal structure formation. Four HD-Zip III genes were targeted by microRNAs (miRNAs), and the miR165/166a-HD-Zip regulatory module formed regulated leaf initiation and leaf polarity establishment. Overall, LcHD-Zip genes play key roles in leaf development of L. chinense. This work provides a foundation for the functional verification of HD-Zip genes identified in this study.

Abstract
BACKGROUND Cognitive impairment is common in the elderly. Prior studies suggest a link between chronic inflammation and cognitive dysfunction, while aging-associated epidermal dysfunction has been connected to elevations in circulating cytokines. OBJECTIVE We assessed here whether improvements in epidermal function can mitigate the progression of cognitive impairment. METHODS This randomized, open-label pilot trial was carried out in two cities in northern China. A total of 200 participants aged ≥65 years were randomly assigned to the emollient-treated and untreated groups at 1:1 ratio. Participants in the treated group were treated topically with Atopalm cream® twice-daily from November to the following May each year for three consecutive years, while the untreated subjects served as controls. The Global Deterioration Scale (GDS) was used to assess the severity of cognitive impairment, while epidermal biophysical properties were measured on the forearms and the shins in parallel. RESULTS Over the three-year trial, GDS significantly increased from baseline (p<0.0001) in the controls, while in the treated group, GDS stabilized. While stratum corneum hydration on the forearms did not change significantly in the controls, transepidermal water loss rates (TEWL), significantly increased by the end of the trial compared to baselines in the controls (p<0.0001). On the forearms of the treated group, stratum corneum hydration increased (p<0.0001) while skin surface pH decreased from baseline (p<0.0001). CONCLUSIONS These results suggest that improvements in epidermal function with topical emollient can mitigate the progression of cognitive impairment. However, the sample size was relatively small, and trials in a larger cohort are needed to validate the present results.

Abstract
Objective: To understand the infectious status of Lyme disease among patients with arthritis symptoms in Hainan Province, and to provide a theoretical basis for prevention and control of Lyme disease. Methods: From 2013 to 2018, sampling surveys had been conducted in medical institutions in 8 cities in Hainan Province(Haikou, Sanya, Danzhou, Dongfang, Wenchang, Qionghai, Qiongzhong, Wuzhishan), 2 311 patients serum samples were collected with arthritis symptoms, and descriptive research were conducted base on the collected clinical data. The Indirect Fluorescent-Antibody Test (IFA) method was used for preliminary screening of Lyme disease antibody, the Western Blot (WB) method was used for IFA positive samples confirmation. Statistical analysis using χ2 test. Results: 2 311 serum samples were tested by IFA, and 166 were positive with the positive rate of 7.18%. Further confirmed by WB method, 62 samples were positive, the positive rate of Lyme disease antibody was 2.68%(62/2 311). The positive rate of Lyme disease antibody among patients with arthritis in different regions of Hainan was statistically significant (χ²=40.636,P<0.001), and the positive rate in Qiongzhong city was the highest (8.81%, 14/159). Danzhou's positive rate was the second highest, 5.62%(5/89). Dongfang city had the lowest positive rate (0.51%, 2/394). The positive rates of Lyme disease serum antibody in men and women were 2.79% (33/1 182) and 2.57% (29/1 129), respectively; the positive rates of antibodies between each age groups were in the range of 1.74% to 3.64%. The antibody positive rate of Lyme disease showed no significant difference between gender and age (χ²=0.110,P=0.740 ;χ²=1.938,P=0.747). Conclusion: Patients with arthritis symptoms caused by Borrelia burgdorferi infection were found in 8 cities in Hainan province, but the Lyme disease antibody positive rate was different among cities, with Qiongzhong County being the highest.

Abstract
Abstract
Background
Atrial fibrillation (Afib) leads to beat-to-beat variability in cycle length; however, whether there is associated beat-to-beat variability in the tricuspid annulus (TA) dimensions or variability in the time in cardiac cycle when TA reaches maximal size is unknown.
Purpose
We aim to assess the beat-to-beat variability in the TA dimensions in Afib compared with sinus rhythm (SR).
Methods
Images were obtained from 58 patients (29 in Afib, 29 in SR) undergoing either 3D TTE or TEE examination. We measured TA in 3–6 cardiac cycles per patient using commercially available software (TomTec 4MV).
Results
Median absolute difference in maximal TA area over 3–6 cardiac cycles was 1.60 cm2 (range 0.35 cm2 to 4.08 cm2) in Afib vs. 1.17 cm2 (range 0.32 cm2 to 2.19 cm2) in SR, p=0.0063. Median absolute difference in the maximal circumference was 0.79 cm (range 0.09 cm to 2.2 cm) in Afib vs 0.54 cm (range 0.12 cm to 1.43 cm) in SR, p=0.0175. A total of 118 cardiac cycles were analyzed in patients in SR and 147 in Afib. Timing of maximal TA area was most commonly recorded at end-diastole (80–100% of the R-R interval) in 62% of cycles in SR; however, it was distributed over a broad range in Afib, p<0.0001, [Figure].
Conclusion
Afib leads to significant beat-to-beat variability in the maximal TA area, minimal TA area, maximal TA circumference, and in the time of maximal TA area. These findings suggest that accurate assessment of TA dimensions should be based on continuous tracking of the TA over several cardiac cycles, especially in patients with Afib. These observations have significant implications for device sizing in percutaneous tricuspid valve interventions.

Abstract
Ephedrine abuse has spread in many parts of the world and severely threatens human health. The mechanism of ephedrine-induced toxicity still remains unclear. This study was performed to investigate the effects of ephedrine treatment on the liver and explore the underlying mechanisms. Sprague Dawley rats were divided into saline and ephedrine groups. Rats were treated with ephedrine at 20 mg/kg or 40 mg/kg ( n = 10) by oral gavage daily for 7 days. Pathological changes were examined by hematoxylin and eosin staining and terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling assay. Enzyme-linked immunosorbent assays were used to measure the liver functional markers, oxidative stress markers, and inflammatory cytokines. Real-time polymerase chain reaction and Western blot were used to measure gene and protein expression, respectively. Our data showed that ephedrine treatment increased hepatocellular cell apoptosis and impaired liver function. Moreover, ephedrine treatment increased oxidative stress and inflammatory responses, which may be due to the increase of transforming growth factor β (TGF-β)/Smad3 expression. Our study demonstrated that short-term treatment of ephedrine caused liver toxicity in rats through regulating TGF-β/Smad pathway.

Abstract
Increasing evidence has revealed a significant association between microorganisms and oral squamous cell carcinoma (OSCC). Porphyromonas gingivalis, the keystone pathogen in chronic periodontitis, is considered an important potential etiologic agent of OSCC, but the underlying immune mechanisms through which P. gingivalis mediates tumor progression of the oral cancer remain poorly understood. Our cohort study showed that the localization of P. gingivalis in tumor tissues was related to poor survival of patients with OSCC. Moreover, P. gingivalis infection increased oral lesion multiplicity and size and promoted tumor progression in a 4-nitroquinoline-1 oxide (4NQO)–induced carcinogenesis mouse model by invading the oral lesions. In addition, CD11b+ myeloid cells and myeloid-derived suppressor cells (MDSCs) showed increased infiltration of oral lesions. Furthermore, in vitro observations showed that MDSCs accumulated when human-derived dysplastic oral keratinocytes (DOKs) were exposed to P. gingivalis, and CXCL2, CCL2, interleukin (IL)–6, and IL-8 may be potential candidate genes that facilitate the recruitment of MDSCs. Taken together, our findings suggest that P. gingivalis promotes tumor progression by generating a cancer-promoting microenvironment, indicating a close relationship among P. gingivalis, tumor progression of the oral cancer, and immune responses.

Abstract
Both live attenuated (HA-L) and inactivated (HA-I) hepatitis A vaccine were licensed for routine use in China. Although phase 1, 2 and 3 clinical studies of both vaccines have been completed, further systematic evaluation of their immunogenicity and immunological persistence under phase 4 clinical studies in a wide range of conditions and involving large populations is necessary. A phase IV clinical trial (NCT02601040) was performed in 9000 participants over 18 months of age. Geometric mean concentrations (GMCs) and seroconversion rates (SRs) were compared at five time points during 3 years for 1800 individuals among them. The SRs of HA-L and HA-I were 98.08% (95% CI 95.59%-99.38%) and 99.64% (95% CI 98.93%-100.00%) respectively 28 days after administration of the first dose, and remained at 97.07% (95% CI 94.31%-98.73%) or above and 96.73% (95% CI 94.07%-98.42%) or above respectively during the following 3 years. The GMCs for both the HA-L and HA-I groups showed that both vaccines elicited high anti-HAV titres, considerably more than the threshold of protection needed against HAV infection in humans, and these titres were sustained. Hence, both HA-I and HA-L vaccines could provide an excellent long-term protective effect, and supported the routine use of both vaccines.

Abstract
The key to produce inorganic heterogeneous nanostructures, and to integrate multiple functionalities, is to enhance or at least retain the functionalities of different components of materials. However, this ideal scenario is often deteriorated at the interface of the heterogeneous nanostructures due to lattice mismatches, resulting in downgraded performance in most hybrid nanomaterials. Here, we report that there is a narrow window in controlling temperature in a Lewis acid-base reaction process to facilitate epitaxial alignment during the synthesis of hybrid nanomaterials. We demonstrate a perfectly fused NaYF4:Yb,Tm@ZnO heterogeneous nanostructure, in which the semiconductor ZnO shell can be epitaxially grown onto lanthanide-doped upconversion nanoparticles. By achieving a matched crystal lattice, the interface defects and crystalline grain boundaries are minimized to enable more efficient energy transfer from the upconversion nanoparticles to the semiconductor, resulting in both enhanced upconversion luminescence intensity and superior photoelectrochemical properties. This strategy provides an outstanding approach to endow lanthanide-doped upconversion nanoparticles with versatile properties.

Abstract
Renal fibrosis is the common final manifestation of chronic kidney diseases and usually results in end-stage renal failure. In this study, we evaluated the effect of fingolimod (FTY720), an analogue of sphingosine 1-phosphate (S1P), as a treatment for the unilateral ureteral obstruction (UUO)-induced renal fibrosis animal model. We treated mice with FTY720 at a dosage of 1 mg/kg/day by intragastric administration from day 1 until day 7. The control group received the same amount of saline. FTY720 reduced significantly the urine albumin/creatinine ratio (UACR) in treated UUO mice. FTY720 treatment also caused a significant decrease in interstitial expansion and collagen deposition in the kidney, accompanied by reduced mononuclear cell recruitment and inflammatory cytokine expression. In addition, the expression levels of the endothelial cell adhesion molecules P-selectin and vascular cell adhesion protein 1 (VCAM-1) were suppressed in the ligated kidney by FTY720 administration, suggesting reduced renal endothelial cell activation. Furthermore, in renal interstitial fibroblast normal rat kidney (NRK)-49F cells, FTY720 significantly affected transforming growth factor (TGF)-β-induced α-smooth muscle actin (SMA) expression and collagen synthesis by inhibiting both the Mothers against decapentaplegic homologue (Smad)2/3 and phosphatidylinositol 3-kinase/protein kinase B/glycogen synthase kinase 3 beta (PI3K/AKT/GSK3β) signalling pathways. S1P1 knock-down by siRNA reversed this effect significantly in our fibroblast cell culture model. Therefore, FTY720 attenuates renal fibrosis via two different mechanisms: first, FTY720 suppresses the synthesis of extracellular matrix in interstitial fibroblasts by interfering with TGF-β signalling; and secondly, FTY720 affects endothelial cell activation and chemokine expression, thereby reducing immune cell recruitment into the kidney.

Abstract
Abstract
The polypropylene (PP) samples were prepared at different molding temperature and their properties and structures were studied. The nearby melting point extrusion and molten extrusion were used to mold PP samples. The tensile strength of PP samples with molding nearby melting point extrusion had a 20.46% increase compared with samples with conventional extrusion. The same phenomenon occurred in Vicat softening temperature and there was a 13.9% increase. Differential scanning calorimetry (DSC) showed the degree of crystallinity for samples by nearby melting point extrusion increased 2.74% compared with samples by molten extrusion. The nearby melting point extrusion molding was beneficial to refine crystalline grain and the results can be proved in XRD, DSC and SEM tests.

Abstract
Multiple drug resistance is a challenging issue in the clinic. There is growing evidence that the G-protein-coupled estrogen receptor (GPER) is a novel mediator in the development of multidrug resistance in both estrogen receptor (ER)-positive and -negative breast cancers, and that cancer-associated fibroblasts (CAFs) in the tumor microenvironment may be a new agent that promotes drug resistance in tumor cells. However, the role of cytoplasmic GPER of CAFs on tumor therapy remains unclear. Here we first show that the breast tumor cell-activated PI3K/AKT (phosphoinositide 3-kinase/AKT) signaling pathway induces the cytoplasmic GPER translocation of CAFs in a CRM1-dependent pattern, and leads to the activation of a novel estrogen/GPER/cAMP/PKA/CREB signaling axis that triggers the aerobic glycolysis switch in CAFs. The glycolytic CAFs feed the extra pyruvate and lactate to tumor cells for augmentation of mitochondrial activity, and this energy metabolically coupled in a 'host-parasite relationship' between catabolic CAFs and anabolic cancer cells confers the tumor cells with multiple drug resistance to several conventional clinical treatments including endocrine therapy (tamoxifen), Her-2-targeted therapy (herceptin) and chemotherapy (epirubicin). Moreover, the clinical data from 18F-fluorodeoxyglucose positron emission tomography/computed tomography further present a strong association between the GPER/cAMP/PKA/CREB pathway of stromal fibroblasts with tumor metabolic activity and clinical treatment, suggesting that targeting cytoplasmic GPER in CAFs may rescue the drug sensitivity in patients with breast cancer. Thus, our data define novel insights into the stromal GPER-mediated multiple drug resistance from the point of reprogramming of tumor energy metabolism and provide the rationale for CAFs as a promising target for clinical therapy.

Abstract
Internal tandem duplication (ITD) mutation in Fms-like tyrosine kinase 3 gene (FLT3/ITD) represents an unfavorable genetic change in acute myeloid leukemia (AML) and is associated with poor prognosis. Metabolic alterations have been involved in tumor progression and attracted interest as a target for therapeutic intervention. However, few studies analyzed the adaptations of cellular metabolism in the context of FLT3/ITD mutation. Here, we report that FLT3/ITD causes a significant increase in aerobic glycolysis through AKT-mediated upregulation of mitochondrial hexokinase (HK2), and renders the leukemia cells highly dependent on glycolysis and sensitive to pharmacological inhibition of glycolytic activity. Inhibition of glycolysis preferentially causes severe ATP depletion and massive cell death in FLT3/ITD leukemia cells. Glycolytic inhibitors significantly enhances the cytotoxicity induced by FLT3 tyrosine kinase inhibitor sorafenib. Importantly, such combination provides substantial therapeutic benefit in a murine model bearing FLT3/ITD leukemia. Our study suggests that FLT3/ITD mutation promotes Warburg effect, and such metabolic alteration can be exploited to develop effective therapeutic strategy for treatment of AML with FLT3/ITD mutation via metabolic intervention.

Abstract
Mesenchymal stromal cells (MSCs) have been shown to reverse radiation damage to marrow stem cells. We have evaluated the capacity of MSC-derived extracellular vesicles (MSC-EVs) to mitigate radiation injury to marrow stem cells at 4 h to 7 days after irradiation. Significant restoration of marrow stem cell engraftment at 4, 24 and 168 h post irradiation by exposure to MSC-EVs was observed at 3 weeks to 9 months after transplant and further confirmed by secondary engraftment. Intravenous injection of MSC-EVs to 500cGy exposed mice led to partial recovery of peripheral blood counts and restoration of the engraftment of marrow. The murine hematopoietic cell line, FDC-P1 exposed to 500cGy, showed reversal of growth inhibition, DNA damage and apoptosis on exposure to murine or human MSC-EVs. Both murine and human MSC-EVs reverse radiation damage to murine marrow cells and stimulate normal murine marrow stem cell/progenitors to proliferate. A preparation with both exosomes and microvesicles was found to be superior to either microvesicles or exosomes alone. Biologic activity was seen in freshly isolated vesicles and in vesicles stored for up to 6 months in 10% dimethyl sulfoxide at -80 °C. These studies indicate that MSC-EVs can reverse radiation damage to bone marrow stem cells.

Abstract
Thiolactomycin (TLM) is a thiotetronate antibiotic that selectively targets bacterial fatty acid biosynthesis through inhibition of the β-ketoacyl-acyl carrier protein synthases (KASI/II) that catalyse chain elongation on the type II (dissociated) fatty acid synthase. It has proved effective in in vivo infection models of Mycobacterium tuberculosis and continues to attract interest as a template for drug discovery. We have used a comparative genomics approach to uncover the (hitherto elusive) biosynthetic pathway to TLM and related thiotetronates. Analysis of the whole-genome sequence of Streptomyces olivaceus Tü 3010 producing the more ramified thiotetronate Tü 3010 provided initial evidence that such thiotetronates are assembled by a novel iterative polyketide synthase-nonribosomal peptide synthetase, and revealed the identity of other pathway enzymes, encoded by adjacent genes. Subsequent genome sequencing of three other thiotetronate-producing actinomycetes, including the Lentzea sp. ATCC 31319 that produces TLM, confirmed that near-identical clusters were also present in these genomes. In-frame gene deletion within the cluster for Tü 3010 from Streptomyces thiolactonus NRRL 15439, or within the TLM cluster, led to loss of production of the respective thiotetronate, confirming their identity. Each cluster houses at least one gene encoding a KASI/II enzyme, suggesting plausible mechanisms for self-resistance. A separate genetic locus encodes a cysteine desulfurase and a (thiouridylase-like) sulfur transferase to supply the sulfur atom for thiotetronate ring formation. Transfer of the main Tü 3010 gene cluster (stu gene cluster) into Streptomyces avermitilis led to heterologous production of this thiotetronate, showing that an equivalent sulfur donor can be supplied by this host strain. Mutational analysis of the Tü 3010 and TLM clusters has revealed the unexpected role of a cytochrome P450 enzyme in thiotetronate ring formation. These insights have allowed us to propose a mechanism for sulfur insertion, and have opened the way to engineering of the biosynthesis of TLM and other thiotetronates to produce novel analogues.

Abstract
Hemorrhagic transformation (HT) is a feared complication of cerebral ischemic infarction, especially following the use of thrombolytic therapy. In this study, we examined whether docosahexaenoic acid (DHA; 22:6n-3), an omega-3 essential fatty acid family member, can protect the brain from injury and whether DHA can decrease the risk of HT enhanced by hyperglycemia after focal ischemic injury. Male Sprague-Dawley rats were injected with 50% dextrose (6ml/kg intraperitoneally) to induce hyperglycemia 10min before 1.5h of filament middle cerebral artery occlusion (MCAO) was performed. Treatment with DHA (10mg/kg) 5min before reperfusion reduced HT and further improved the 7-day neurological outcome. It also reduced infarct volume, which is consistent with the restricted DWI and T2WI hyperintensive area. Reduced Evans Blue extravasation and increased expression of collagen IV indicated the improved integrity of the blood-brain barrier (BBB) in DHA-treated rats. Moreover, DHA reduced the expression of the intercellular adhesion molecule-1 (ICAM-1) in the ischemic injured brain. Therefore, we conclude that DHA attenuated hyperglycemia-enhanced HT and improved neurological function by preserving the integrity of BBB and reducing inflammation.

Abstract
The activation of cancer-associated fibroblasts (CAFs) is a key event in tumor progression, and alternative extracellular matrix (ECM) proteins derived from CAFs induce ECM remodeling and cancer cell invasion. Here we found that miR-200 s, which are generally downregulated in activated CAFs in breast cancer tissues and in normal fibroblasts (NFs) activated by breast cancer cells, are direct mediators of NF reprogramming into CAFs and of ECM remodeling. NFs with downregulated miR-200 s displayed the traits of activated CAFs, including accelerated migration and invasion. Ectopic expression of miR-200 s in CAFs at least partially restored the phenotypes of NFs. CAF activation may be governed by the targets of miR-200 s, Fli-1 and TCF12, which are responsible for cell development and differentiation; Fli-1 and TCF12 were obviously elevated in CAFs. Furthermore, miR-200 s and their targets influenced collagen contraction by CAFs. The upregulation of fibronectin and lysyl oxidase directly by miR-200 or indirectly through Fli-1 or TCF12 contributed to ECM remodeling, triggering the invasion and metastasis of breast cancer cells both in vitro and vivo. Thus, these data provide important and novel insights into breast CAF activation and ECM remodeling, which trigger tumor cell invasion.

Abstract
In order to investigate the effect of kaolin coated with liquid macromolecular modifier (LKL) particles on the processability, thermal and mechanical properties of PVC materials, rigid poly(vinyl chloride) (PVC)/kaolin and PVC/kaolin coated with liquid macromolecular modifier (PVC/LKL) composites were both fabricated by melt mixing. The processability, dynamic mechanical behavior, mechanical properties and micro-structure of PVC/kaolin and PVC/LKL composites were studied by using torque rheometer, dynamic mechanical analysis (DMA), universal mechanical testing machine and scanning electron microscope (SEM). The results showed that the LKL particles improved the processability of PVC materials, while restrained the degradation of PVC materials during melt mixing due to the plasticization, toughening effect and compatibilization of the liquid macromolecular modifier (LMM). Moreover, the LMM could promote LKL particles uniformly dispersed in PVC matrix, and enhance the interface adhesion between LKL particles and PVC matrix. The notched impact strength and Tg of the PVC/LKL composites achieved 4.0 kJ/m2 and 95.2 °C, which enhanced 29% and 6 °C with respect to neat PVC materials, respectively.

Abstract
A colored phenotype is an important feature of ornamental fish. In mammals, microphthalmia-associated transcription factor (MITF) was found to regulate the development of melanocytes. In this study, the mitfa cDNA was first cloned from the Japanese ornamental (Koi) carp (Cyprinus carpio L.), an important ornamental freshwater fish. The full-length cDNA of the mitfa gene contains 1634 bp, coding for 412 amino acids in Koi. The identity degree of mitfa amino acid sequences between the Koi carp and zebrafish is 92.9%. We tested the expression of the mitfa gene in several varieties of Koi using reverse transcription-polymerase chain reaction and found that the mitfa gene is highly expressed in the skin tissues of the Taisho sanke and the Procypris merus. Interestingly, the mitfa gene was also expressed in the Kohaku and Yamabaki ogon, although melanocytes were not observed in the skin. Koi carp embryos were transparent and colorless, while after hatching, different types of pigment cells successively emerged in a fixed order. In Taisho sanke, melanocytes first appeared in the trunk at approximately 12 days of age. Subsequently, there was a large area of melanocytes by 30 days of age. The expression level of the mitfa mRNA was low in early embryos and newly hatched larvae, and increased to high levels in 30-day-old fry. The results show that the mitfa gene is involved in regulating fish body color in the development of both melanocytes and pigment cells.

Abstract
We report a new surgical technique of open carpal tunnel release with subneural reconstruction of the transverse carpal ligament and compare this with isolated open and endoscopic carpal tunnel release. Between December 2007 and October 2011, 213 patients with carpal tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to 67) were recruited from three different centres and were randomly allocated to three groups: group A, open carpal tunnel release with subneural reconstruction of the transverse carpal ligament (n = 68); group B, isolated open carpal tunnel release (n = 92); and group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no significant difference between the groups in terms of severity of symptoms or lateral grip strength. Compared with groups B and C, group A had significantly better functional status, cylindrical grip strength and pinch grip strength. There were significant differences in Michigan Hand Outcome scores between groups A and B, A and C, and B and C. Group A had the best functional status, cylindrical grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during carpal tunnel decompression maximises hand strength by stabilising the transverse carpal arch.
