Abstract
Virus-like particles encapsulating HBV-RNA represent a serum biomarker for assessing viral replication activity in clinical practice. However, baseline levels of serum HBV-RNA and their associations with viral replicative intermediates and liver disease in phases of chronic hepatitis B remain unknown. In this cross-sectional study, 102 patients were categorized into immune-tolerant (IT), HBeAg-positive immune active (HBeAg+IA), inactive carrier (IC) and HBeAg-negative immune active (HBeAg-IA) phases. HBV-RNA in serum samples and in 66 paired liver biopsies were quantified and correlated with serum ALT levels, histopathological scores and the levels of other viral replicative intermediates. Mean levels of serum HBV-RNA differed among phases, with the highest levels among IT (6.78 ± 0.83 log10 copies mL-1 ) patients, followed by HBeAg+IA (5.73 ± 1.16 log10 copies mL-1 ), HBeAg-IA (4.52 ± 1.25 log10 copies mL-1 ) and IC (2.96 ± 0.40 log10 copies mL-1 ) patients. Serum HBV-RNA levels correlated with HBV DNA in all phases, although correlations with other viral replicative intermediates weakened or disappeared when cases were stratified into phases. Distinct compositions of viral products were found among phases: the ratio of HBsAg to serum HBV-RNA was highest in IC patients, while the ratio of serum HBV-RNA to intrahepatic HBV-RNA and the ratio of intrahepatic HBV-DNA to intrahepatic HBV-RNA were significantly higher in IT patients. In conclusion, baseline levels of HBV-RNA and the composition of viral replicative intermediates differ significantly across the natural course of chronic HBV infection. These findings shed light on the nature of viral replication and pathogenesis of disease among different phases of chronic HBV infection.

Abstract
BACKGROUND Recent upper respiratory tract infection (URI) is associated with increased incidence of perioperative complications in children undergoing open heart surgery. As a result, surgery is often postponed. However, the effect of recent URI on the incidence of perioperative complications in children undergoing therapeutic cardiac catheterisation is unknown. We investigated the perioperative outcomes of congenital heart disease (CHD) children with recent URI who underwent elective therapeutic catheterisation. METHODS We prospectively included children treated for CHD. Before surgery, parents or legal guardians were interviewed to complete a questionnaire on the child's demographics, history of asthma and passive smoking, and URI symptoms. Recorded perioperative respiratory adverse events (PRAEs) included laryngospasm, bronchospasm, breath holding, oxygen desaturation, and severe cough. Information on postoperative dysphoria, fever, copious sputum, and vomiting was obtained by telephone 24 h after surgery. RESULTS Of 363 included children, 169 had recently (within 2 weeks) had a URI. The URI did not affect the incidence of laryngospasm, bronchospasm, breath holding, fever, or vomiting. The incidence of desaturation, severe cough, dysphoria, and copious sputum were significantly increased. Independent risk factors for PRAEs in children with a recent URI included age, passive smoking, and presence of rhinorrhoea or moist cough. The lengths of stay in the hospital and intensive care unit were not significantly different between groups. CONCLUSION Although recent URI increased the incidence of PRAEs in children undergoing therapeutic cardiac catheterisation, most CHD patients with recent URI can undergo elective therapeutic cardiac catheterisation without serious adverse events or prolonged hospitalisation.

Abstract
Abstract
Background
Gastric adenocarcinoma is a common cause of cancer death globally. It remains unclear whether coexisting diabetes mellitus influences survival in patients with this tumour. A cohort study was conducted to determine whether coexisting diabetes increases mortality in gastric adenocarcinoma.
Methods
This nationwide population-based cohort study included all patients diagnosed with gastric adenocarcinoma in Sweden between 1990 and 2014. Cox proportional hazards regression and competing risks regression were used to assess the influence of coexisting diabetes on disease-specific mortality in gastric adenocarcinoma with adjustment for sex, age, calendar year and co-morbidity (Charlson Co-morbidity Index score excluding diabetes).
Results
Among 23 591 patients with gastric adenocarcinoma, 2806 (11·9 per cent) had coexisting diabetes. Overall, patients with diabetes had a moderately increased risk of disease-specific mortality after diagnosis of gastric adenocarcinoma compared with those without diabetes, as shown by both Cox regression (hazard ratio (HR) 1·17, 95 per cent c.i. 1·11 to 1·22) and competing risks regression (sub-HR 1·08, 1·02 to 1·13). The HRs for disease-specific mortality were notably increased in diabetic patients without other co-morbidity (HR 1·23, 1·15 to 1·32) and in diabetic patients who had surgery with curative intent (HR 1·27, 1·16 to 1·38).
Conclusion
These findings indicate a worse prognosis in patients with gastric adenocarcinoma and coexisting diabetes compared with those without diabetes.

Abstract
Objective:The next-generation sequencing technology (NGS) was used to perform genetic testing on children diagnosed with sensorineural hearing loss in outpatient clinics.The information on the status and inheritance of disease causing genes in deafness was analyzed to provide a theoretical basis for genetic counseling, prenatal diagnosis, and birth defects prevention.Method:Ninety-four cases of sensorineural deafness diagnosed by medical history, audiological examination, and imaging examination were collected in our department.Next-generation sequencing was used to detect the region of exons of 159 genes, 6 mitochondrial genes, and 3 miRNAs related to deafness. The Sanger sequencing verification was performed on the parents of the probands to find out the gene expression status and relationship between the probands and the parents.Result:Of the 94 children with deafness,70 had severe sensorineural hearing loss, 13 had moderate to severe hearing loss, 8 had moderate hearing loss, and 3 had mild hearing loss.Twenty-three cases of cariogenic mutations were detected by next generation sequencing,and the total mutation rate was 24.5%. There were 11 cases of GJB2 mutations, including 6 homozygous mutations of 235delC, 4 heterozygous mutations of 235delC and 299_300del heterozygous mutation of 235delC and c.176_191del.There are 5 cases of SLC26A4 gene mutations, including 2 cases of homozygous mutations of c.919-2A> G, one case of c.919-2A> G and c.2168A>G compound heterozygous mutations, c.919-2A> G and c.754T> C compound heterozygous mutation in 1 case, c.919 2A> G and c.416-418del complex heterozygous mutation in 1 case. There were 2 cases of MT RNR1 mutations, and 1 case of STRC,KCNQ1,USH2A,POU3F4, and MITF mutations.Conclusion:The next-generation sequencing has features such as rapid, high throughput, and low cost, which is beneficial to medication guidance, genetic counseling, and marriage and parenting guidance,and help to effectively prevent or reduce the occurrence of hereditary deafness..

Abstract
AIM To evaluate the correlation between miRNA-375 and cell proliferation and apoptosis in glioma cancer cell. METHODS Collecting 30 cases of glioma cancer patients and 30 cases of cerebral infarction patients. The miRNA-375 and CTGF protein expressions were evaluated by ISH and IHC methods. In the cell experiment, the U87 cells were divided into 3 groups: NC group (the cells were treated with normal method); BL group (the cells were transfected with empty vector) and miRNA group (the cells were transfected with miRNA-375). The U87 cell proliferation and apoptosis rates and cell cycle of the different groups were measured by MTT and flow cytometry. The relative proteins (CTGF, EGFR, AKT, Erk and P21) expressions were measured by WB assay. RESULTS The miRNA-375 and CTGF expressions of glioma cancer tissues were significantly different compared with those of no-cancer tissues (p < 0.05, respectively). In the cell experiments, the cell proliferation of miRNA group was significantly decreased compared with that of NC group (p < 0.05); the cell apoptosis and G1 phase rate of miRNA group was significantly decreased compared with NC group (p < 0.05, respectively). Depending on the WB assay, the CTGF, EGFR, AKT, Erk and P21 proteins expressions of miRNA group were significantly different compared with proteins expressions of NC group (p < 0.05, respectively). CONCLUSION miRNA-375 over-expression suppresses glioma cancer cells development via CTGF-EGFR pathway (Fig. 3, Ref. 30).

Abstract
Background Most patients with multiple myeloma (MM) are considered to be incurable, and relapse owing to minimal residual disease (MRD) is the main cause of death among these patients. Therefore, new technologies to assess deeper response are required. Patients and methods We retrospectively analyzed 125 patients with MM who underwent high-dose melphalan plus autologous stem-cell transplantation (ASCT) to detect MRD in autograft/bone marrow (BM) cells using a next-generation sequencing (NGS)-based method and allele-specific oligonucleotide-polymerase chain reaction (ASO-PCR). Results NGS-based method was applicable to 90% and this method had at least one to two logs greater sensitivity compared to ASO-PCR. MRD negative by NGS [MRDNGS(−)] (defined as <10−6) in post-ASCT BM cases (n = 26) showed a significantly better progression-free survival (PFS) (96% at 4 years, P < 0.001) and overall survival (OS) (100% at 4 years, P =0.04) than MRDNGS(+) in post-ASCT BM cases (n = 25). When restricting the analysis to the 39 complete response cases, patients who were MRDNGS(−) (n = 24) showed a significantly better PFS than those that were MRDNGS(+) (n = 15) (P =0.02). Moreover, MRDNGS(−) in post-ASCT BM cases (n = 12) showed significantly a better PFS than MRDNGS(+) cases (n = 7) where MRD was not detected by ASO-PCR (P = 0.001). Patients whose autografts were negative by NGS-based MRD assessment (<10−7) (n = 19) had 92% PFS and 100% OS at 4 years post-ASCT. Conversely, the NGS-based MRD positive patients who received post-ASCT treatment using novel agents (n = 49) had a significantly better PFS (P = 0.001) and tended to have a better OS (P= 0.214) than those that were untreated (n = 33). Conclusions Low level MRD detected by NGS-based platform but not ASO-PCR has significant prognostic value when assessing either the autograft product or BM cells post-ASCT.

Abstract
OBJECTIVE To investigate the expression of G-quadruplex antibody BG4 in human gastric cancer AGS cells and assess its functions in attenuating proliferation and promoting apoptosis in gastric cancer. MATERIALS AND METHODS BG4 high-expression gastric cancer AGS cell line was established by pEGFP-N1-BG4 transient transfection. AGS cells transfected with pEGFP-N1 plasmids were included into the pEGFP-N1 group and those not transfected with plasmids were included into the negative control group. Cell counting kit-8 (CCK8) assay was performed to examine the AGS cell proliferation ability, while flow cytometry was used to detect the cell cycle distribution and cell apoptosis. Cell migration was measured using Transwell migration and wound healing assay. Then the expression levels of cell apoptosis associated factors were determined. The mRNA and protein expressions of human telomerase reverse transcriptase (hTERT), B-cell lymphoma 2 (Bcl-2), Bcl-2 associated X (Bax) were examined with real-time quantitative polymerase chain reaction (PCR) and Western blotting, respectively. RESULTS The results revealed that pEGFP-N1-BG4 group exhibited reduced proliferation and migration, induction of apoptosis. hTERT and Bcl-2 mRNA and protein levels in pEGFP-N1-BG4 group were down-regulated compared with those in the pEGFP-N1 group and control group, but there were no significant differences in Bax mRNA and protein levels compared with those in the pEGFP-N1 group and control group. CONCLUSIONS We showed that the expression of BG4 in the gastric cancer cell line AGS inhibits cell proliferation and promotes apoptosis though inducing telomere to form G-quadruplex structure and attenuating telomerase activity, thus resulting in reduced expression of hTERT and Bcl-2.

Abstract
Herpetospermum caudigerum (H. caudigerum; HC), popularly known as Sejimeiduo in Tibet, it is widely used in Tibetan traditional medicine for the treatment of dyspepsia, liver and colic diseases. This study was designed to evaluate the effect of H. caudigerum extract (HCE) on suppressing liver injury induced by carbon tetra chloride (CCl4). For this purpose, we used CCl4 to induce acute liver injury in mouse model. The protective effects of HCE against liver injury were evaluated by biochemical parameters, histopathological and immunohistochemical staining. The results showed that the superoxide dismutase (SOD) activity was significantly increased with the increasing dose of HCE as compared to the CCl4-treated group (p less than 0.01); while AST and ALT levels in serum, MDA and MPO in liver were reduced in a dose-dependent manner. The histopathology showed that HCE treatment promoted the recovery of histopathological changes in liver in a dose-dependent way. Meanwhile, there was a higher expression of caspase-3 and NF-κB in the nucleus of several liver cells in the CCl4-induced group, and a low expression of caspase-3 and NF-κB were found with the increasing dose of HCE. Therefore, the present study suggests that HCE is a potent hepatoprotective agent that can treat acute liver injury and this ability may be attributed towards its anti-inflammatory and antioxidant potential.

Abstract
Diabetes mellitus increases periodontitis and pathogenicity of the oral microbiome. To further understand mechanisms through which diabetes affects periodontitis, we examined its impact on periodontal ligament fibroblasts in vivo and in vitro. Periodontitis was induced by inoculation of Porphyromonas gingivalis and Fusobacterium nucleatum in normoglycemic and diabetic mice. Diabetes, induced by multiple low-dose injections of streptozotocin increased osteoclast numbers and recruitment of neutrophils to the periodontal ligament, which could be accounted for by increased CXC motif chemokine 2 (CXCL2) and receptor activator of nuclear factor kappa B ligand (RANKL) expression by these cells. Diabetes also stimulated a significant increase in nuclear factor kappa B (NF-κB) expression and activation in periodontal ligament (PDL) fibroblasts. Surprisingly, we found that PDL fibroblasts express a 2.3-kb regulatory unit of Col1α1 (collagen type 1, alpha 1) promoter typical of osteoblasts. Diabetes-enhanced CXCL2 and RANKL expression in PDL fibroblasts was rescued in transgenic mice with lineage-specific NF-κB inhibition controlled by this regulatory element. In vitro, high glucose increased NF-κB transcriptional activity, NF-κB nuclear localization, and RANKL expression in PDL fibroblasts, which was reduced by NF-κB inhibition. Thus, diabetes induces changes in PDL fibroblast gene expression that can enhance neutrophil recruitment and bone resorption, which may be explained by high glucose-induced NF-κB activation. Furthermore, PDL fibroblasts express a regulatory element in vivo that is typical of committed osteoblasts.

Abstract
Gastroesophageal reflux disease and esophageal dysmotility are prevalent in patients with advanced lung disease and are associated with graft dysfunction following lung transplantation. As a result, many transplant centers perform esophageal function testing as part of the wait-listing process but guidelines for testing in this population are lacking. The aim of this study is to describe whether symptoms of gastroesophageal reflux correlate with abnormal results on pH-metry and high-resolution manometry and can be used to identify those who require testing. We performed a retrospective cohort study of 226 lung transplant candidates referred for high-resolution manometry and pH-metry over a 12-month period in 2015. Demographic data, results of a standard symptom questionnaire and details of esophageal function testing were obtained. Associations between the presence of symptoms and test results were analyzed using Fisher's exact tests and multivariable logistic regression. The most common lung disease diagnosis was interstitial lung disease (N = 131, 58%). Abnormal pH-metry was seen in 116 (51%) patients and the presence of symptoms was significantly associated with an abnormal study (p < 0.01). Dysmotility was found in 98 (43%) patients, with major peristaltic or esophageal outflow disorders in 45 (20%) patients. Symptoms were not correlated with findings on esophageal high-resolution manometry. Fifteen of 25 (60%) asymptomatic patients had an abnormal manometry or pH-metry. These results demonstrate that in patients with advanced lung disease, symptoms of gastroesophageal reflux increase the likelihood of elevated acid exposure on pH-metry but were not associated with dysmotility. Given the proportion of asymptomatic patients with abnormal studies and associated post-transplant risks, a practice of universal high-resolution manometry and pH-metry testing in this population is justifiable.

Abstract
The Northern Hemisphere experienced dramatic changes during the last glacial, featuring vast ice sheets and abrupt climate events, while high northern latitudes during the last interglacial (Eemian) were warmer than today. Here we use high-resolution aerosol records from the Greenland NEEM ice core to reconstruct the environmental alterations in aerosol source regions accompanying these changes. Separating source and transport effects, we find strongly reduced terrestrial biogenic emissions during glacial times reflecting net loss of vegetated area in North America. Rapid climate changes during the glacial have little effect on terrestrial biogenic aerosol emissions. A strong increase in terrestrial dust emissions during the coldest intervals indicates higher aridity and dust storm activity in East Asian deserts. Glacial sea salt aerosol emissions in the North Atlantic region increase only moderately (50%), likely due to sea ice expansion. Lower aerosol concentrations in Eemian ice compared to the Holocene are mainly due to shortened atmospheric residence time, while emissions changed little. Past climate changes in Greenland ice were accompanied by large aerosol concentration changes. Here, the authors show that by correcting for transport effects, reliable source changes for biogenic aerosol from North America, sea salt aerosol from the North Atlantic, and dust from East Asian deserts can be derived.

Abstract
AIM To evaluate the early treatment response to chemotherapy in patients with lung cancer using dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI). MATERIALS AND METHODS Twenty-two patients with lung cancer underwent DCE-MRI before chemotherapy and 1 week after the start of the first course of chemotherapy. Pharmacokinetic parameters (Ktrans, Kep, and Ve) derived from DCE MRI were generated using the post-processing platform. These parameters and corresponding changes were compared between responders and non-responders after treatment using Student's t or Mann-Whitney U-tests. Diagnostic efficiency of kinetic parameters in differentiating responders from non-responders after 1 week of chemotherapy was also investigated. RESULTS Thirteen responders after 1 week of chemotherapy had a significant decrease in Ktrans and Ve compared with the pretreatment value (p<0.05), and had no significant changes in Kep (p>0.05). Nine non-responders had no significant changes in Ktrans, Kep, and Ve compared with the pretreatment value (p>0.05). Changes in Ktrans (ΔKtrans) were significantly larger in responders than that in non-responders (p<0.05). Changes in Ve and Kep (ΔVe andΔKep) were without statistical significance after treatment between responders and non-responders (p>0.05). The cut-off value of ΔKtrans in best predicting tumour's chemotherapeutic response was 0.032/min and the corresponding AUC (area under the curve), sensitivity, specificity, and accuracy were 0.821, 84.62%, 77.78%, and 81.82%, respectively. CONCLUSION DCE MRI may be useful for evaluating the early response to chemotherapy in patients with lung cancer, but larger, more definitive studies are needed.

Abstract
This is a single centre study in mainland China aiming to evaluate the reliability, validity and responsiveness of the Chinese version of EORTC QLQ-BN20, designed by The European Organization for Research and Treatment of Cancer Quality of Life Group to evaluate the life quality of patients with brain tumour, cancer or metastases. One hundred and eighty-eight patients with primary or secondary brain cancer from Hunan Provincial Tumor Hospital during September 2013 to June 2014 completed the Chinese EORTC QLQ-C30/BN20 questionnaires developed by translation, back translation and cultural adaptation. Results were statistically analysed using SPSS17.0. The internal consistency (Cronbach's α coefficient) was between .753 and .869, the correlation coefficients among items and its own dimension were bigger than .4, and all items had a better correlation with its own dimension. The Spearman was used to analyse the correlation of each dimension between EORTC QLQ-BN20 and EORTC QLQ-C30, and the result showed that individual dimensions were moderately correlated, other dimensions were weakly correlated. In conclusion, the Chinese version of EORTC QLQ BN20 questionnaire had great relevance, reliability, convergent validity and discriminant validity. It provides a valuable tool for the assessment of health-related quality of life in clinical studies of Chinese patients with primary or secondary brain cancer.

Abstract
Previous studies showed that paraquat (PQ) caused the apoptosis of dopaminergic neurons by inducing the generation of oxygen radical. The purpose of this study is to explore PQ-induced microglial inflammatory response and its underlying molecular mechanisms. The murine microglia BV2 cell line was used. After stimulation with PQ and lipopolysaccharides (positive control), the concentrations of tumor necrosis factor-α (TNF-α), interleukin 1β (IL-1β), and interleukin 6 (IL-6) in the culture supernatant and mRNA expression of TNF-α and IL-1β were determined by ELISA and quantitative real-time Polymerase Chain Reaction (PCR), respectively. The protein expression of heat shock protein 60 (HSP60) and toll-like receptor 4 (TLR4), along with the mRNA expression of transcription factors of nuclear factor κB-p65 (NF-κB-p65) and activated protein 1 (AP1, c-fos, and c-jun dimer) were evaluated with western blot and quantitative real-time PCR, respectively. The results showed that PQ activated microglia, which was characterized by increasing the generation and upregulated mRNA expression of pro-inflammatory cytokines, TNF-α, IL-1β, and IL-6. In addition, PQ significantly enhanced the expressions of HSP60 and TLR4 proteins in BV2 cells, as well as NF-κB-p65, c-fos, and c-jun mRNA. These findings suggest that PQ can activate microglia and enhance the expression and secretion of pro-inflammatory cytokines in a HSP60/TLR4 signaling, leading to the inflammatory response.

Abstract
Nonlinear optical processes are strongly dominated by phase relationships among electromagnetic fields involved. In this paper, we theoretically and experimentally show that in a Raman-resonant four-wave-mixing process, the first anti-Stokes and Stokes generations can be tailored in a variety of ways by manipulating the phase relationships among the relevant electromagnetic fields.

Abstract
Pulmonary adenofibroma is an extremely rare benign primary tumor of the lung, with characteristic bi-phasic differential pattern. They are usually sub-pleural solid pulmonary nodules with clear margins. The tumor is composed of glands and peri-gland stroma. The glands are often quite simple, forming long and narrow tubules, with uniformly monolayer lining cells. Combined papillary or phyllodes structures were reported in some cases. The stromal cells are spindle-shaped and look mild, mixed with the collagen bands. Up till now, only a few cases of pulmonary adenofibroma have been reported all over the world. And because of the limited recognition, this tumor is easily misinterpreted as malignancy in frozen section or biopsy specimens. We reported a new case of pulmonary adenofibroma. The mass peripherally located in the left lobe of the lung, found by chance in a 74-year-old woman. The patient underwent a wedge resection of the left lung by the thoracoscope, because of the slowly gradual enlargement of the mass annually. An oval grayish-white nodule was sub-pleural located in the specimen, with solid and rubbery texture, but without a distinct capsule. Two distinct components of simple glands and mild spindle cell stroma were found to mix together uniformly under the microscope. Collagen bands of various widths evenly surrounded each stromal cell. A few small coarse papillae or phyllodes structures were randomly distributed in some area. The immunohistochemical staining pattern of the glandular cells was accordant with typeIIalveolar epithelium. Stromal cells were positive with CD34, B-cell lymphoma-2 (Bcl-2), CD99 and estrogen receptor (ER), while S-100, smooth muscle actin (SMA) and all the mesothe-lium markers were negative. The patient was disease free after the surgery, although the follow-up time was only one year. Besides the new case above, we also reviewed all the reported cases, and tentatively discussed the probable histological origin of pulmonary adenofibroma.

Abstract
Follicular helper T (Tfh) cells and follicular regulatory T (Tfr) cells are critical for the development and maintenance of germinal centre (GC) and humoral immune responses. Accumulating evidence has demonstrated that the dysregulation of either Tfh cells or Tfr cells contributes to the pathogenesis of autoimmune diseases. We aim to investigate the roles of circulating Tfh cells and circulating Tfr cells in the pathogenesis of primary biliary cholangitis (PBC). A total of 34 patients with PBC and 27 health individuals were enrolled in this study. Flow cytometry revealed that circulating Tfh (CD4+ CXCR5+ CD127hi CD25lo ) cells were increased, but Tfr (CD4+ CXCR5+ CD127lo CD25hi ) cells and ratio of Tfr/Tfh were dramatically decreased in PBC patients compared with healthy controls. The Tfr/Tfh ratio was negatively correlated with level of serum IgM. Meanwhile, we also observed effector memory (CCR7lo PD-1hi ) Tfh cells and Tfr cells were dramatically increased, but central memory (CCR7hi PD-1lo ) Tfh cells and Tfr cells were decreased in PBC patients compared with healthy controls. Effector memory Tfr cells were positively correlated with level of serum ALP. These results indicate that an imbalance of circulating Tfr cells and Tfh cells may be involved in the immunopathogenesis of PBC and may provide novel insight for the development of PBC therapies.

Abstract
AIMS Exercise intervention might be a promising approach to prevent gestational diabetes mellitus. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the effect of exercise intervention on gestational diabetes mellitus. METHODS PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of exercise intervention on gestational diabetes mellitus were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcome was the incidence of gestational diabetes mellitus, preterm birth, and gestational age at birth. Meta-analysis was performed using random-effect model. RESULTS Five RCTs involving 1872 patients were included in the meta-analysis. Overall, compared with control intervention, exercise intervention was found to significantly reduce the risk of gestational diabetes mellitus (std. mean difference 0.62; 95% CI 0.43-0.89; P = 0.01), but demonstrated no influence on preterm birth (OR 0.93; 95% CI 0.44-1.99; P = 0.86), gestational age at birth (std. mean difference -0.03; 95% CI -0.12 to 0.07; P = 0.60), glucose 2-h post-OGTT (std. mean difference -1.02; 95% CI -2.75 to 0.71; P = 0.25), birth weight (std. mean difference -0.10; 95% CI -0.25 to 0.04; P = 0.16), Apgar score less than 7 (OR 0.78; 95% CI 0.21-2.91; P = 0.71), and preeclampsia (OR 1.05; 95% CI 0.53-2.07; P = 0.88). CONCLUSIONS Compared to control intervention, exercise intervention was found to significantly reduce the incidence of gestational diabetes mellitus, but had no significant influence on preterm birth, gestational age at birth, glucose 2-h post-OGTT, birth weight, Apgar score less than 7, and preeclampsia.

Abstract
Osteosarcoma is the most frequent primary bone tumor originating from adolescents and young adults. Despite improvements in the chemo- or radio- therapy of osteosarcoma patients, survival rate has not increased and drug resistance becomes a major factor that limits the effectiveness. Therefore, investigation of new treatment modalities is urgently required to optimize therapeutic options. Our previous study described an oncogenic role of miR-214 through promotion of osteosarcoma cells proliferation. In this study, we report miR-214 contributes to cisplatin resistance in osteosarcoma cells. Overexpression of miR-214 decreased the cisplatin sensitivity. By establishing an osteosarcoma cisplatin resistant cell line, we find miR-214 is significantly upregulated in cisplatin resistant cells. Moreover, we show miR-214 promotes anaerobic glycolysis rates of osteosarcoma cells but suppresses mitochondrial oxidative phosphorylation. Consistently, cisplatin resistant cells exhibit upregulated glycolysis but decreased mitochondrial oxidative phosphorylation, a phenotype called "Warburg effect". Finally, we demonstrate inhibition of glycolysis by either glycolysis inhibitor or miR-214 inhibition significantly re-sensitizes cisplatin resistant osteosarcoma cells. In summary, this study illustrates a miRNA-involved chemosensitivity of osteosarcoma and will contribute to the developments of therapeutic agents for the anti-chemoresistance treatments.

Abstract
OBJECTIVE To investigate the effect of a new tumor-suppressor gene Arid2 on the expression level of CD44 and the mechanism that Arid2 regulates the invasion and metastasis in human hepatocellular carcinoma cells HepG2 and Huh7. METHODS Recombinant pGL3-CD44 reporter plasmids were transfected into hepatoma cell lines HepG2 and Huh7 cells infected with adenovirus Arid2(Ad-Arid2). Dual luciferase assays were used to determine the relative luciferase activities of reporter plasmids. Western blot technique was used to detect the influence of Arid2 on the expression of transmembrane glycoprotein CD44. Cell migration assays of tumor cells were employed to observe the impact of overexpression of Arid2 on the invasion and metastasis abilities of tumor cells. The sizes of transplanted tumors were recorded to observe the growth of subcutaneous transplanted tumors in nude mice. Statistical significance was analyzed by one-way ANOVA for multiple comparisons, and independent-samples t-test was utilized to compare two groups. RESULTS Luciferase assay showed cells were transfected with different length of CD44 reporter plasmids, and their relative luciferase activities were improved to different degrees, compared with pGL3-Basic control. Meanwhile, the mean luciferase activities of pGL3-CD44 -791~+224bp reporter plasmids were significantly repressed by the overexpression of Arid2 which inhibition rates were up to 73.83%±0.92%(P< 0.05, HepG2) or 48.99%±1.37% (P <0.05, Huh7), compared with Ad-GFP control. Western blot results showed that CD44 protein expression was obviously decreased by overexpression of Arid2. Cell migration assays confirmed that the invasion and metastasis abilities were inhibited by increasing Arid2 expression in Human HepG2 or Huh7 cells, which inhibition rates were 66.95%±0.59%(P< 0.05)in HepG2 cells and 73.86%±0.49%(P< 0.05) in Huh7 cells respectively. The animal experiment results indicated that Arid2 could obviously delay or restrict the subcutaneous transplanted tumors growth in nude mice, which was declined by 98.57%±0.34%(P< 0.05). CONCLUSION CD44 promoter activities and protein expressions were significantly down-regulated by Arid2 in vitro. The growth and metastasis of tumors were obviously restrained in the hepatocellular carcinoma cells and nude models. In brief, these researches indicate CD44 may play important roles in the process where the invasion and metastasis of hepatocellular carcinoma cells are under the control of Arid2.The studies introduce and evaluate the relationships between Arid2 and CD44, and further provide a new research direction with the occurrence and development of hepatocellular carcinoma.

Abstract
BACKGROUND/OBJECTIVES We aimed to determine the alteration of Tannerella forsythia and coating color on the dorsal tongue, and fatty food liking in catch-up fat in adult (CUFA), as well as the probable associations between fat accumulation, insulin resistance (IR) and these changes. SUBJECTS/METHODS T. forsythia on the tongue dorsum, fatty food liking, fat accumulation and insulin sensitivity were investigated in CUFA humans and rats, and tongue-coating color was observed in CUFA individuals. We further determined the changes of fatty food liking, fat accumulation and IR in T. forsythia-infected rodents by oral lavage. RESULTS Increases in fat accumulation, IR, percentage of subjects with yellow tongue coating and that with T. forsythia detected were observed in CUFA individuals. Additionally, the fat ranking scores were significantly lower and the hedonic ratings of low-fat options of sampled food were lower, while the ratings of high-fat options were remarkably higher in CUFA subjects. Additionally, T. forsythia level elevated in CUFA rats, and fatty food liking, fat accumulation and IR increased in CUFA and T. forsythia-infected animals, with the increases in T. forsythia infection and fatty food liking preceding the occurrence of fat accumulation and IR. CONCLUSIONS T. forsythia and yellow coating on the dorsal tongue and fatty food liking associate fat accumulation and IR in CUFA. Moreover, we tentatively put forward that T. forsythia, which is very important in yellow tongue-coating microbiota, and its consequent increases in fatty food liking, might be crucial in the development of fat accumulation and IR in CUFA.

Abstract
This study aimed to test the effects of xuezhikang, a cholestin extract that contains statin-like components, on arterial stiffness in patients with essential hypertension. One hundred hypertensive patients from the Chinese PLA General Hospital were randomly allocated to receive xuezhikang (1200 mg/day, orally) or placebo (same capsules containing only pharmaceutical excipients). Physical examination outcomes, lipid profile, high sensitivity C-reactive protein (hs-CRP) levels, matrix metalloproteinases-9 (MMP-9) levels, and arterial outcomes, including stiffness parameter (β), pressure-strain elasticity modulus (Ep), arterial compliance (AC), augmentation index (AI), and one-point pulse wave velocity (PWVβ) were obtained at baseline and after 6 months of the intervention. Xuezhikang significantly reduced β (8.4±3.1 vs 6.8±2.1, P=0.007), Ep (122.8±43.9 vs 100.7±33.2, P=0.009), PWVβ (6.7±1.2 vs 6.1±1.0, P=0.013), low-density lipoprotein cholesterol (3.4±0.6 vs 2.9±0.5, P=0.001), hs-CRP [2.1 (0.4-10.0) vs 1.4 (0.3-4.1), P=0.020], and MMP-9 (17.2±2.4 vs 12.7±3.8, P <0.001) compared to baseline. The placebo had no effect on these parameters. The changes of PWVβ in the xuezhikang group was significantly associated with the changes of hs-CRP and MMP-9 (r=0.144, P=0.043; r=0.278, P=0.030, respectively) but not with lipid profile changes. Our research showed xuezhikang can improve the parameters of arterial stiffness in hypertensive patients, and its effect was independent of lipid lowering.

Abstract
Objective:To investigate the expression of miR 34a in epithelial cells of nasal polyps (NPs) and to determine its effects on hypoxia induced epithelial mesenchymal transition (EMT).method:Nasal epithelial cells (NECs) were collected from NPs and normal inferior turbinates. miR-34a expression was detected by means of quantitative reverse transcriptase polymerase chain reaction. In addition, normal NECs were cultured under normoxia/hypoxia conditons. The effects of miR-34a mimics on hypoxia induced EMT were investigated.result:miR-34a was specifically down-regulated in NECs of NP. Hypoxia decreased miR-34a expression in vitro. Furthermore, E-cadherin and α-SMA were down-regulated and up-regulated, respectively. miR-34a mimics transfection can reverse this process.Conclusion:miR-34a suppress hypoxia-induced EMT in NECs. The down-regulation of miR-34a may contribute to nasal polypogenesis.
