Abstract
Background: The Zusanli (ST36) acupoint has been associated with treatment of various gastrointestinal conditions. There have been no studies of acupuncture therapy for paralytic postoperative ileus (PPOI). Materials and methods: Patients with PPOI following gastrectomy for gastric cancer were randomized to receive ST36 acupoint injection with neostigmine, gluteal intramuscular injection with 1.0 mg neostigmine, ST36 acupuncture alone, or standard therapy. The main outcome was the effectiveness rate for recovery of peristalsis. Secondary outcomes were time to bowel sound recovery, time to first flatus, and time to first defecation. Tertiary outcomes were drug-related adverse events, including abdominal pain, diarrhea, nausea, vomiting, tearing, delirium, seizure, and anxiety. Results: ST36 acupoint injection with neostigmine and gluteal intramuscular injection of neostigmine gave a higher rate of peristalsis recovery, and the ST36 acupoint injection group showed significantly higher total effectiveness rate than that of the intramuscular injection group. These interventions gave significantly shorter times to bowel sound recovery, shorter times to first flatus and first defecation compared with ST36 acupuncture and standard post-operative therapy (P < 0.01). ST36 acupoint injection group gave shorter time to bowel sound recovery, shorter time to first flatus and first defecation than those of the intramuscular injection group (P < 0.01). Drug-related adverse events in the intramuscular injection group were more serious than in the ST36 acupoint injection group (P < 0.05). Conclusion: ST36 acupoint injection with neostigmine is safe and effective for treatment of PPOI.

Abstract
Celastrus orbiculatus Thunb. has been used as a remedy against cancer and inflammatory diseases for thousands of years in China. Maspin is expressed in normal cells and downregulated in prostate tumor cells. The underlying mechanisms between C. orbiculatus extract (COE) and maspin remain unclear. In the present study, 3 target-specific 19–25 nucleotide maspin small interfering RNAs were designed and synthesized to knockdown maspin expression. The effects of COE on MGC-803/maspin− cell proliferation were evaluated by the MTT assay. Apoptosis was measured by flow cytometry. Invasive activity was measured with the Transwell assay and the associated molecular mechanisms were assessed by western blot analysis. The results demonstrated that COE significantly promoted the expression of maspin (P<0.01) to induce apoptosis and inhibit invasion and migration in MGC803 cells. The expression levels of phosphorylated (p)-p38 mitogen-activated protein kinase (MAPK), phospho-extracellular regulated protein kinase (Erk), B cell lymphoma-2-associated X protein and caspase-3 were increased in the MGC-803/maspin− cells in a dose-dependent manner. The Erk, B-cell lymphoma 2, p-Akt, Akt and p-mechanistic target of rapamycin (mTOR) protein in MGC-803/maspin− cells were reduced in a dose-dependent manner. This indicated that COE may inhibit invasion and migration through phosphoinositide 3-kinase/Akt/mTOR and MAPK signaling pathways in MGC-803/maspin− cells. In conclusion, COE has the ability to improve the expression of maspin to induce apoptosis and inhibit invasion and migration in human gastric adenocarcinoma cells.

Abstract
Objective: To investigate the clinical features and genetic characteristics of patients with ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) gene variants. Method: The clinical data of a patient with ENPP1 homozygous variants from Capital Institute of Pediatrics was collected, the related literature was searched from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, National Center from Biotechnology Information and PubMed by using search term "ENPP1" , "hypophosphatemic rickets" . The literature retrieval was confined from 1980 to February 2017. The clinical manifestations, bone metabolism examinations, X-RAY and genotypes were reviewed. Result: Our patient was an 11 years old girl, with 7 years history of lower limb malformation. She showed significant valgus deformity of the knee (genu valgum). Metabolic examination revealed reduced level of plasma phosphate (0.86 mmol/L), a normal level of plasma calcium (2.30 mmol/L) and an elevated alkaline phosphatase level of 688 IU/L. The calcium-phosphorus product was 25.9. A homozygous nonsense variants of ENPP1 gene, c.783C>G (p.Tyr261X) in exon 7 was identified in the patient. Both parents were heterozygous carriers. Literature review identified 3 Chinese patients from one publication and 17 cases from twenty one publications around the world. None of the patients was found PHEX variants which is the most common variants among hypophosphatemic rickets patients. The disease onset age was 11 months to 10 years. Eight patients had short stature, five patients had the history of generalized arterial calcification of infancy. Four suffered from deafness, three showed localized calcifications of arteries, three patients manifested pseudoxanthoma elasticum and two suffered from ossification of posterior longitudinal ligament. Nine missense variants, six splicing variants and 4 nonsense variants were reported among these twenty patients. c.783C>G was found in two Chinese patients. Conclusion: ENPP1 gene mutation was a cause of patient with hypophosphatemic rickets. Comorbid features included generalized arterial calcification of infancy, early onset hearing loss, pseudoxanthoma and ossification of posterior longitudinal ligament. ENPP1 gene testing should be performed on hypophosphatemic rickets patients without PHEX gene variants. Long-term follow up is recommended. The most common types of ENPP1 gene variants were nonsense/splicing variants. The gene c.783C>G was the most common variants in Chinese patients.

Abstract
Objective: To investigate the clinical characteristics of respiratory syncytial virus(RSV)bronchiolitis and molecular biological characteristics of RSV in children in Beijing. Method: In a systematic retrospective study, 2 296 nasopharyngeal aspirates (NPA) were collected from children diagnosed with bronchiolitis from July 2006 to June 2016 for respiratory virus screening using direct immunofluorescence assay (DFA). For specimens positive for RSV, subgroup A or B was confirmed by real time RT-PCR and genotype of RSV was determined by amplifying the full G glycoprotein gene and sequencing. Clinical data were evaluated by the modified Tal score to compare the severity between RSV subtypes, as well as genotypes. Statistical analyses were performed using t test, Mann-Whitney U test and χ(2) test. Result: In 2 296 bronchiolitis cases, 961(41.9%) were RSV positive, including 719(74.8%) RSV A and 236 (24.6%) RSV B. The dominant RSV subtype changed from year to year: A-A-B-B-A-A-B-AB-A-AB and more bronchiolitis cases were identified in RSV A dominant years. Six genotypes of RSV A (NA1, NA2, NA3, NA4, GA5 and ON1) and 5 genotypes of RSV B (BA3, BA7, BA9, BA10 and CB1) were prevalent in Beijing. The dominant genotypes of RSV A were NA1 (55.9%) with high rates (50.0%-100%) before 2014 and ON1 (39.1%), mainly detected after 2014, while BA9 (90.6%) was the absolute dominant RSV B genotype. No significant difference in the severity of bronchiolitis was shown between cases of RSV A and B. Children positive for NA1 were more likely to stay longer in hospital (Median time: 8 days) compared to the group positive for ON1(Median time: 6 days ) (U=1.035, P=0.005) and had higher proportion of moderate to severe degree symptoms (Moderate: 41.0%, Severe: 10.0%) compared with ON1 group (Moderate: 22.9%, Severe: 4.3%) (U=9.785, P=0.008). In the group positive for ON1, more children had fever (ON1: 38.6%, NA1: 15.0%) (χ(2)=11.064, P=0.001) and more were younger than 3 months(ON1: 54.3%, NA1: 33.0%) (χ(2)=77.408, P<0.001). Conclusion: The dominant RSV subgroup changed from year to year with a shifting pattern. The correlation between RSV genotypes and the severity of disease was documented in the study.

Abstract
OBJECTIVE To compare the prevalence characteristics of influenza viruses in children in Beijing during 2014-2015 and 2015-2016 influenza seasons. METHOD Throat swabs were collected weekly from children with influenza-like illnesses who visited in Children's Hospital affiliated to Capital Institute of Pediatrics during the period from September 2014 to May 2016.Influenza viruses A and B viruses were detected by real-time RT-PCR, followed by identification of H3N2, H1N1pdm, B/Victoria-like and B/Yamagata-like.The prevalence characteristics of influenza viruses was estimated by means of descriptive statistics.The t test and chi-square test were used to compare median age and gender ratio of infected children among different types of influenza viruses. RESULT Out of 1 821 throat swabs collected, 139 (7.6%) were positive for H3N2 and 43 (2.4%) for H1N1pdm and 204 (11.2%) for influenza B virus, including 108 for B/Victoria-like and 96 for B/Yamagata-like.The median age of H1N1pdm infected children ((3.3±2.2) years) was significantly younger than that of H3N2 ((4.7±3.2) years) and influenza B virus((4.9±2.8) years) (H1N1pdm vs. H3N2: t=2.848, P=0.002; H1N1pdm vs. influenza B, t=3.682, P=0.000). Two epidemic peaks were presented in 2014-2015 influenza season, dominated definitely by H3N2 and B/Yamagata-like, respectively, while one delayed peak started at the 51(st) week, 2015, co-circulated with H3N2, H1N1pdm and influenza B viruses, among which B/Victoria-like virus was predominant during the 2015-2016 season. CONCLUSION Prevalence characteristics of influenza viruses are different between 2014-2015 and 2015-2016 influenza seasonal epidemics in children in Beijing. It is important to monitor the genetic variations of influenza viruses and to keep close attention to influenza B virus as well as influenza A virus.

Abstract
Celastrus orbiculatus is a traditional medicinal plant used in the anti-inflammatory and analgesic treatment of various diseases. A previous study demonstrated that ethyl acetate extract of C. orbiculatus (COE) exhibited significant antitumor effects. However, studies concerning the effects and mechanism of COE in terms of suppressing the epithelial-mesenchymal transition (EMT) in human gastric adenocarcinoma cells have not been performed at present. The present study hypothesized that COE may inhibit EMT in gastric adenocarcinoma cells by regulating cell cytoskeleton rearrangement. The effect of COE on the viability of AGS cells was detected by MTT assay. An EMT model was induced by transforming growth factor-β1. Cell cytoskeleton staining, laser scanning confocal microscopy and electronic microscopy were used to detect the changes in cell morphology and microstructure of gastric adenocarcinoma cells prior and subsequent to COE treatment. Invasion and migration assays were used to observe the effect of COE on the metastatic ability of AGS cells in vitro. The effect of COE on the expression of Cofilin 1 and EMT biomarkers, including Epithelial-cadherin, Neural-cadherin, Vimentin and matrix metalloproteinases, was examined by western blotting in AGS cells. The correlation between Cofilin 1 and EMT was investigated with immunofluorescence and cytoskeleton staining methods. The results demonstrated that COE may significantly inhibit the process of EMT in AGS cells, and that this was concentration-dependent. In addition, COE significantly downregulated the level of Cofilin 1 in a concentration-dependent manner. In conclusion, these results suggested that Cofilin 1 was directly involved in the process of EMT in AGS cells, and that it served an important function. COE may significantly inhibit EMT in AGS cells, potentially by inhibiting the activation of the Cofilin 1 signaling pathway. The present study may provide a basis for the development of novel anticancer drugs and the development of novel therapeutic strategies, targeting Cofilin 1 protein.

Abstract
Epithelial-mesenchymal transition (EMT) is an important biological process whereby malignant tumor cells obtain the ability to migrate, invade, resist apoptosis and degrade the extracellular matrix. We found that Cofilin1 (CFL1) expression was elevated in clinical gastric cancer specimens and correlated with biomarkers of EMT in BGC-823 gastric cancer cells. BGC-823 cells exhibited EMT phenotypes and increased metastatic ability when induced by TGF-β1. By contrast, BGC-823 cells transfected with Lv-siRNA-CFL1 did not exhibit EMT phenotypes under the same inducing conditions. As CFL1 expression increased, EMT cell filopodia stretched out. In addition, the ultrastructures observed using transmission electron microscopy indicated that silencing of CFL1 markedly inhibited depolymerization of fibrous actin and cytoskeletal reorganization during EMT. Similar results were obtained in vivo. These findings demonstrate that CFL1 induces EMT by promoting cytoskeletal rearrangement. Our results may provide the basis for developing new anticancer drugs to inhibit CFL1.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The traditional Chinese medicine (TCM) herb Celastrus orbiculatus is an important folk medicinal plant in China that has been used as an anti-inflammatory, antitumor, and analgesic in various diseases. The ethyl acetate extract of C. orbiculatus (C. orbiculatus extract, COE) was reported to show significant antitumor effects. However, no study in China or abroad has reported the effect and mechanism of COE in triggering apoptosis of gastric cancer (GC) cells. AIM OF STUDY To further uncover the molecular mechanism underlying COE's apoptotic and anti-proliferative effects and lay a foundation for the development of novel, effective antitumor TCM agents. MATERIALS AND METHODS The effect of COE on AGS and BGC-823 GC cell viability was examined using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis of AGS and BGC-823 cells induced by COE was analyzed using flow cytometry and a mitochondrial membrane potential assay kit (JC-1). The proliferating GC cells were identified and examined using a 5-bromo-2'-deoxyuridine (BrdU) staining kit and flow cytometric analysis. A western blot assay was used to detect the effect of COE on apoptosis-related proteins, B-cell lymphoma-2 (Bcl-2), Bcl-extra-large (Bcl-xL), Bcl-2-like protein 12 (Bcl-L12), Bcl-2-associated X protein (Bax), and caspase as well as proliferation-related proteins, phosphoinositide 3-kinase (PI3K)/Akt/mechanistic target of rapamycin (mTOR)/p70s6k. Transmission electron microscopy (TEM) and an animal imaging technique were used to evaluate the microstructure of apoptotic GC cells and the effect of COE on tumor cell growth in vivo, respectively. RESULTS The results indicate that COE significantly inhibited proliferation and induced apoptosis of GC AGS and BGC-823 cell lines both in vivo and in vitro. COE significantly decreased the cell mitochondrial membrane potential. Moreover, COE downregulated the levels of Bcl-2, Bcl-xL, and PI3K/Akt/mTOR/p70s6k while those of Bax and caspase were upregulated. More interestingly, COE altered the microstructure of the mitochondria. CONCLUSION All these data collectively indicate that COE not only has significant antiproliferative effects but also has both in vivo and in vitro apoptotic effects. In addition, COE altered the structure and function of the mitochondria, which is another potential pathway for the antitumor activity of COE. These findings may provide a basis for the development of new anticancer TCM candidates.

Abstract
The aim of the present study was to determine the expression of rho-associated coiled-coil-containing protein kinase 1 (ROCK1) and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (PIK3CA) in nasopharyngeal carcinoma (NPC), and to assess the association between the expression of these proteins and the clinicopathological features of NPC. ROCK1 and PIK3CA expressions were assessed in a tissue microarray of sections prepared from the tumors of 81 patients with NPC using immunohistochemistry. Western blot analysis was used to detect ROCK1 and PIK3CA expression in NP69 and 5-8F cells. χ2 analysis revealed that upregulation of ROCK1 was significantly associated with advanced N stage (P=0.032) cancer and increased PIK3CA expression was significantly associated with advanced N stage (P=0.027) and TNM stage (P=0.019) cancer. Furthermore, ROCK1 expression was significantly positively correlated with PIK3CA expression (P=0.01). Western blot analysis demonstrated that levels of ROCK1 (P<0.001) and PIK3CA (P=0.015) were significantly higher in 5-8F cells compared with NP69 cells. The results of the present study indicate that high levels of ROCK1 and PIK3CA expression may be associated with advanced stages in NPC.

Abstract
Background/Aim: The aim of the present study was to investigate the efficacy of a traditional Chinese medicine (TCM), VEGFR-3 antibody-conjugated ginsenoside Rg 3 nanoemulsion (VRIN), targeting lymphangiogenesis, on the inhibition of tumor growth and metastasis in an orthotopic mouse model of human gastric cancer. Materials and Methods: An orthotopic nude-mouse model of gastric cancer was established with the red fluorescent protein (RFP)-expressing human gastric cancer cell line NUGC-4-RFP. The tumor-bearing mice were treated with vehicle (0.2 ml normal saline every other day, iv), 5-FU (20 mg/kg once a week, i.p.) and VRIN (1 mg/kg every other day, i.v.). Real-time fluorescence imaging was performed to assess tumor inhibition in each group. Metastasis was evaluated by open fluorescence imaging at autopsy. The expression of lymphangiogenesis-related factors VEGF-C, VEDF-D and VEGFR-3 in the tumors were analyzed by immunohistochemistry and real-time RCP. Results: VRIN and 5-FU significantly inhibited primary tumor growth as compared to vehicle control (p<0.05). However, significant inhibition of lymph-node metastasis was only found in the VRIN-treated group (p<0.05). The expression of VEGF-C, VEGF-D and VEGFR-3 in the tumor was suppressed by VRIN treatment (p<0.05). Expression of VEGF-D and VEGFR-3 in the 5-FU-treated group was not significantly increased (p>0.05). No obvious toxicity was found in VRIN- and 5-FU-treated groups. Conclusion: Lymphangiogenesis-targeted ginsenoside Rg 3 immune-nanoemulsion inhibited tumor growth and reduced lymphatic metastasis by suppressing expression of VEGF-C, VEGF-D and VEGFR-3 in an orthotopic mouse model of human gastric cancer. Our study demonstrates the potential of TCM as an effective targeted treatment for metastatic gastric cancer.

Abstract
Abstract
ERα-positive breast cancers comprise approximately 80% of all newly diagnosed cases. Current treatment approaches targeting ER signaling include antagonizing and/or downregulating ER or reducing estrogen levels. Faslodex (fulvestrant) is the only clinically-approved agent that is both a potent ER antagonist and downregulator but has limitations given its pharmacokinetics and route of administration. Over the past several years, targeted ER therapies have focused on developing selective estrogen receptor downregulators (SERDs, i.e, GDC-0810, GDC-0927, AZD9496, RAD1901). The mechanisms involved in ER downregulation by SERD binding are not completely understood, but evidence suggests that conformational changes in the receptor upon ligand binding combined with specific co-regulator interactions destabilize the receptor making it a target for passive proteasomal degradation. We hypothesized that the complex ER pharmacology required for SERD-based passive degradation might be different across various ER-positive cell lines and that targeted degradation of the receptor by actively recruiting the ubiquitin-proteasome machinery would provide a better approach for reducing ER levels. To test this hypothesis, we developed potent molecules directed against ER using our pioneering technology—proteolysis targeting chimeras (PROTACs). PROTACs are heterobifunctional molecules that actively recruit specific E3 ligases resulting in ubiquitylation and degradation of target proteins. When testing for ER degradation using several SERDs and ER PROTACs, we discovered that both fulvestrant and ER PROTACs provided robust degradation in all ER-positive lines (<1 nM 50% degradation; >90% reduction) whereas other SERDs did not degrade or only modestly degraded the receptor. Importantly, MCF-7 cells were uniquely sensitive to SERD-based degradation of ER compared to other cell lines. Subcutaneous administration of fulvestrant (1mpk) or ER PROTACs (10 mpk) reduced uterine ER alpha levels in immature rats (>65% reduction). PROTAC-mediated degradation of ER was also achieved in breast cancer xenografts. To further validate the PROTAC mechanism, incubation of ER-positive cells with ER PROTACs resulted in increased levels of poly-ubiquitylated ERα when compared to SERDs. Lastly, to demonstrate the specificity of PROTAC-mediated ERα degradation, we utilized a cellular expression proteomics-based approach to examine over 7,000 proteins. In this experiment, only ERα and several known proteins whose genes are regulated by ERα, were significantly reduced by PROTACs. It remains to be seen how the current class of investigational downregulators will perform in the clinic. More importantly, a better understanding of the therapeutic potential and benefit of degrading the receptor instead of inhibiting the receptor needs to be explored. To that end, we continue to develop and characterize novel ER PROTACs with the anticipation that targeted ERα degradation will provide a greater clinical benefit than receptor antagonism.

Abstract
Objective: To evaluate the clinical value of a rapid respiratory syncytial virus (RSV) antigen detection in point-of-care testing (POCT). Method: A total of 209 specimens, including 78 throat swabs (TS) and 131 nasopharyngeal aspirates (NPAs), were collected from inpatients who visited the Children's Hospital Affiliated to the Capital Institute of Pediatrics and were diagnosed as acute respiratory infection from 5 January to 7 February, 2015. These specimens were tested for RSV by a rapid antigen detection kit which was compared with reverse transcription polymerase chain reaction (RT-PCR) and direct immunofluorescence assay (DFA) for RSV detection. Result: Compared with DFA for NPAs, the sensitivity and specificity of rapid antigen detection were 83.9% and 97.3%, respectively, with Kappa value of 0.86; Compared with RT-PCR, the sensitivity (NPAs, 74.2%; TS, 77.8%) and specificity (NPAs, 100.0%; TS, 92.0%) of rapid antigen detection were high, too, with Kappa value of 0.74 in NPAs and 0.62 in TS. However, the RSV positive rate of rapid antigen detection in TS (21.7%) from pediatric patients with acute lower respiratory tract infection was lower than that in NPAs (78.3%), as well as that of RT-PCR (7.3% in TS verse 78% in NPAs). The RSV rapid antigen detection kit can be finished in about 10 minutes. Conclusion: With characteristics of high specificity, high sensitivity, being rapid, efficient and easy to operate in comparison with DFA and RT-PCR, RSV rapid antigen detection in this study is suitable for POCT. For pediatric patients with acute respiratory tract infection, NPA was better than TS for RSV detection.

Abstract
OBJECTIVE To present a case of severe ovarian hyperstimulation syndrome (OHSS) in a naturally conceived singleton pregnancy after ovulation induction. CASE A 31-year-old woman with polycystic ovarian syndrome (PCOS) underwent ovulation induction therapy. Six days later, she was admitted to the present hospital with the symptoms of OHSS. Ultrasonography confirmed the single live intrauterine pregnancy, as well as enlarged multicystic ovaries and marked ascites that required abdominal paracentesis. The woman was treated with intravenous infusion, exogenous colloid supplementation, essentiale liver treatment, rocephin anti-infective therapy for skin lymphangitis of left lower limb, and drainage of the ascites. She recovered by day 45 of admission. CONCLUSION Severe OHSS may develop in women with PCOS who undergo ovulation induction therapy. Serious complications may develop rapidly and therefore OHSS must be treated urgently and with multidisciplinary management.

Abstract
Ovarian aging has been associated with increased levels of reactive oxygen species and the deficiencies of antioxidant defense. The antioxidant peroxiredoxin 4 (Prdx4), as a member of Prdx protein family, controls cellular oxidative stress by reducing H2O2 levels. In previous studies, we provided evidence that Prdx4 was abundantly expressed in mouse and human ovaries and expression of Prdx4 in matured follicles was higher than that in immatured follicles. Accordingly, we speculated that Prdx4 expression could be associated with follicle development and it may be as a part of the antioxidative mechanism in follicular development. In this study, we demonstrated that Prdx4 was mainly expressed in the granulosa cells of mouse ovaries and the expression levels significantly increased along development of follicles. However, the expression levels of Prdx4 decreased when mice reached the aged stage (18 months old). Likewise a similar pattern that was observed in the mice study was also found in human ovaries where Prdx4 was expressed lower in premenopausal women than young women. Subsequent in vitro experiments indicated that Prdx4 mRNA and protein levels both increased with H2O2 in a concentrationdependent manner, but decreased rapidly with high concentration of H2O2, and the changes were closely related to cell proliferation. Taken together, these findings argue our understanding on the role of oxidative stress and antioxidant in follicular development and ovarian aging.

Abstract
Celastrus orbiculatus is used as a folk medicine in China for the treatment of numerous diseases. The ethyl acetate extract of Celastrus orbiculatus (COE) also displays a wide range of anti-cancer activities in the laboratory. However, the effectiveness of COE-induced autophagy and its mechanism of action in colorectal cancer cells have not been investigated thus far. The present study analyzed the effect of COE on HT-29 cell viability, apoptosis and autophagy using MTT assay, flow cytometry, transmission electron microscopy and western blotting. Additionally, the autophagy inhibitor 3-methyladenine and the autophagy inducer rapamycin were used to further explore the effects of COE-induced autophagy in HT-29 cells. The present study also examined whether the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/Akt/mechanistic target of rapamycin (mTOR)/p70 ribosomal protein S6 kinase (p70S6K) signaling pathway was involved in the regulation of COE-induced autophagy. The results revealed that COE inhibited HT-29 cell proliferation and decreased cell survival in a time- and dose-dependent manner, and that COE possessed the ability to induce both apoptosis and autophagy in HT-29 cells. Furthermore, autophagy and apoptosis induced by COE synergized to inhibit colorectal cancer growth. In addition, COE treatment decreased the phosphorylation of Akt and its downstream effectors mTOR and p70S6K. Taken together, these results demonstrate that both autophagy and apoptosis were activated during COE treatment of HT-29 cells, and that COE-induced autophagy decreases the viability of HT-29 cells via a mechanism that may depend on the PI3K/Akt/mTOR/p70S6K signaling pathway. Furthermore, compounds that induce autophagy administered in combination with COE may be an attractive strategy for enhancing the anti-tumor potency of COE in colorectal cancer.

Abstract
Constitutive photomorphogenesis 9 signalosome (CSN) consists of a total of eight subunits (CSN1-CSN8) in mammalian cells. CSN6 may promote carcinogenesis by positively regulating v-myc avian myelocytomatosis viral oncogene homolog (Myc) and MDM2 proto-oncogene stability, and is regarded as a potential target for cancer therapy. Quercetin has a substantial anticancer effect on various human cancer cells. The present study investigated the effects of quercetin on HT-29 human colorectal cancer cell viability, apoptosis and cell cycle arrest using an MTT assay, flow cytometry, transmission electron microscopy and western blotting. It was determined that quercetin inhibited HT-29 cell viability in a dose-dependent manner. Cell shrinkage, chromatin condensation and nuclear collapse were observed in the 50, 100 and 200 µM quercetin groups. The exposure of HT-29 cells to quercetin led to significant cell cycle arrest in the S-phase. Western blot analysis revealed that quercetin reduced the protein expression levels of phosphorylated-Akt and increased CSN6 protein degradation; therefore, affecting the expression levels of Myc, p53, B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X protein. The overexpression of CSN6 reduced the effect of quercetin treatment on HT-29 cells, suggesting that quercetin-induced apoptosis may involve the Akt-CSN6-Myc signaling axis in HT-29 cells.

Abstract
BACKGROUND Gliomas are highly aggressive tumors of the nervous system, and current treatments fail to improve patient survival. To identify substances that can be used as treatments for gliomas, we examined the effect of Celastrus orbiculatus extract (COE) on the invasion and migration of human glioblastoma U87 and U251 cells in vitro. METHODS The effects of COE on cell viability and adhesion were tested using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay and cell adhesion assay, respectively. The effects of COE on cell migration and invasion were assessed by a wound-healing assay and transwell migration and invasion assays. The effects of COE on the expression of epithelial-mesenchymal transition (EMT)-related proteins and matrix metalloproteinases (MMPs) were evaluated using western blot and gelatin zymography, respectively. Finally, the effect of COE on actin assembly was observed using phalloidin-tetramethylrhodamine isothiocyanate labeling and confocal laser scanning microscopy. RESULTS We found that COE inhibited the adhesion, migration, and invasion of U87 and U251 cells in a dose-dependent manner. COE reduced N-cadherin and vimentin expression, increased E-cadherin expression, and reduced MMP-2 and MMP-9 expression in U87 and U251 cells. Furthermore, COE inhibited actin assembly in U87 and U251 cells. CONCLUSIONS COE attenuates EMT, MMP expression, and actin assembly in human glioblastoma cells, thereby inhibiting their adhesion, migration, and invasion in vitro.

Abstract
Ras-Association Domain Family 10 (RASSF10) is the last identified member of the RASSF family. The functional characteristics of this new gene in human cancers remain largely unclear. Here, we examined RASSF10 for the biological functions and related molecular mechanisms in hepatocellular carcinoma (HCC). We found that RASSF10 is expressed in normal human liver tissue, but is silenced or down-regulated in 62.5% (5/8) of HCC cell lines. The mean expression level of RASSF10 was significantly lower in primary HCCs compared with their adjacent normal tissues (P<0.005, n=52). The promoter methylation contributes to the inactivation of RASSF10 as demonstrated by bisulfite genomic sequencing and demethylation treatment analyses. Transgenic expression of RASSF10 in silenced HCC cell lines suppressed cell viability, colony formation and inhibited tumor growth in nude mice (QGY7703, P<0.01; HepG2, P<0.05). Furthermore, RASSF10 was shown to induce the cell accumulation in G1 phase with the increase of p27, as well as the decrease of cyclinD1 and CDK2/CDK4. Over-expression of RASSF10 also inhibited HCC cells migration (P<0.01) or invasion (P<0.05). Adhesion genes array revealed that Matrix Metalloproteinase 2 (MMP2) was a downstream effector of RASSF10. RASSF10 acting as a tumor suppressor to inhibit HCC invasion partially mediated by Focal Adhesion Kinase or p38 MAPK to decrease the accumulation of MMP2. Our study suggests that RASSF10 acts as a tumor suppressor for HCC.

Abstract
OBJECTIVE To investigate the method for the measurement of chlorpyrifos in serum by gas chromatography, and to provide a basis for emergency treatment of poisoning in clinical practice. METHODS Venous blood (3.0 ml) was collected from patients. After coagulation, the blood samples were centrifuged at 4 000 r/min for 5 minutes, and 0.5 ml of serum was placed in a glass test tube with a cork; 4.0 ml of ethyl acetate was then added and mixed rapidly, and this solution was subjected to extraction for 5 minutes and centrifuged at 4 000 r/min for 10 minutes. The ethyl acetate layer was placed in a conical tube and extracted twice with the same method. The extract was mixed and blow-dried with nitrogen, and the residue was dissolved with 50.0 μl ethanol. Gas chromatography was used for measurement, with a sample size of 1 μl and a retention time of 9.609 minutes. RESULTS The linear range of this method was 0.2~20.0 μg/ml, and the regression equation was y=2 372.6x+357.2(r=0.999 6). The detection limit of chlorpyrifos in serum was 0.05 μg/ml, and the recovery rate was 84.6%~102.4%. The relative standard deviation was 3.6%~4.8%, and the intra-day and inter-day relative standard deviations were 3.62%~5.10% and 3.77%~4.98%, respectively. CONCLUSION This detection method is accurate, simple, and convenient, and can be used for the clinical diagnosis of chlorpyrifos poisoning.

Abstract
Abstract
Purpose
The Clinical Evaluation of Pertuzumab and Trastuzumab (CLEOPATRA) study showed a 15.7-month survival benefit with the addition of pertuzumab (P) to docetaxel and trastuzumab (TH) as first-line treatment for patients with HER2 overexpressing metastatic breast cancer. We performed a cost-effectiveness analysis to assess the value of the addition of pertuzumab to docetaxel and trastuzumab.
Patient and Methods
We developed a decision-analytic Markov model to evaluate the cost-effectiveness of TH with or without P in U.S. patients with metastatic breast cancer. The model followed patients weekly over their remaining lifetimes. Health states included: stable disease, progressing disease, hospice, and death. Transition probabilities were based on the CLEOPATRA study. Costs reflected the 2014 Medicare rates. Health state utilities were the same as those used in other recent cost-effectiveness studies of trastuzumab and pertuzumab. Outcomes included health benefits expressed as discounted quality-adjusted life-years (QALYs), costs in U.S. dollars, and cost-effectiveness expressed as an incremental cost-effectiveness ratio. One-way and multi-way deterministic and probabilistic sensitivity analyses explored the effects of specific assumptions.
Results
Modeled median survival was 39.4 months (TH) and 56.9 months (THP). The addition of pertuzumab resulted in an additional 1.81 life years gained (0.62 QALYs) at a cost of $472,668 per QALY gained. Deterministic sensitivity analysis showed that THP is unlikely to be cost-effective even under the most favorable assumptions, and probabilistic sensitivity analysis predicted 0% chance of cost-effectiveness at a willingness-to-pay of $100,000 per QALY gained.
Conclusion
The addition of pertuzumab to docetaxel and trastuzumab in patients with metastatic HER2+ breast cancer is unlikely to be cost-effective in the United States.

Abstract
BACKGROUND The relationship between microRNA-1 (miR-1) expression and prognosis has not been reported in hepatocellular carcinoma (HCC). The present study aimed to explore the clinicopathological significance and the prognostic role of miR-1 in HCC. METHODS The expression levels of miR-1 were quantified using real-time quantitative PCR (q-PCR) in 40 surgically resected HCC samples and matched adjacent non-cancerous tissues. RESULTS MiR-1 expression was significantly downregulated in HCC compared with matched non-cancerous tissues. Aberrant miR-1 expression was significantly correlated with gender, expression of hepatitis B virus surface antigen (HBsAg), tumor differentiation, vein invasion, and TNM stage. Patients with low expression of miR-1 had significantly reduced overall survival compared with patients with high expression of miR-1 (p = 0.04).The multivariate Cox regression analysis indicated that miR-1 expression (HR = 2.79; p = 0.005), gender (HR = 0.087; p = 0.005), vein invasion (HR = 0.172; p = 0.007), and TNM stage (HR = 3.421; p = 0.001) were independent prognostic factors for overall survival. CONCLUSIONS Low miR-1 expression is associated with shortened survival time. MiR-1 may act as a potential prognostic biomarker for HCC patients.

Abstract
BACKGROUND Currently in Canada, several bone-targeted agents (btas) with varying characteristics are available for the prevention of skeletal-related events (sres) in patients with bone metastasis secondary to solid tumours. In the present study, we evaluated the preferences of physicians in Canada for the various attributes of the available btas. METHODS Physicians treating patients with bone metastasis from solid tumours were invited to complete an online discrete-choice experiment. Respondents were asked to choose between pairs of hypothetical medications for virtual patients. Each hypothetical medication was described based on predefined key attributes: time until first sre, time until worsening of pain, medication-related annual risk of osteonecrosis of the jaw (onj), medication-related annual risk of renal impairment, and mode of administration. A random-parameters logit model was used to analyze the choices between hypothetical medications and thus infer physician preferences for medication attributes. RESULTS Responses from the 200 physicians who completed the discrete-choice experiment suggested that months until first sre, risk of renal impairment, and months until worsening of pain were considered the most important attributes affecting choice of bta. The annual risk of onj was considered the least important attribute. CONCLUSIONS When making treatment decisions about the choice of bta for patients with bone metastasis from solid tumours, delaying sres and worsening of pain, and reducing the risk of renal impairment are primary considerations for physicians in Canada.

Abstract
Purpose: The current study examined quality of life, progression of disease, and survival rate during chemotherapy in newly diagnosed non-small cell lung cancer (NSCLC) patients with depression (n=48) and without depression (n=78). Further, the study explored the hypothesis that the survival benefit resulted from the chemotherapy of docetaxel and cisplatin (the DC regimen). Patients and Methods: In total, 126 patients with newly diagnosed NSCLC participated in a cross-sectional study of DC chemotherapy integrated with standard oncology care in depression and non-depression groups. The health-related quality of life (HR-QOL) was assessed using the quality of life questionnaire for Chinese cancer patients receiving chemobiotherapy (QLQ-CCC). Depression was self-rated using the Zung Self-Rating Depression Scale (Z-SDS). Both HR-QOL and Z-SDS were completed before the first and after the last cycle of chemotherapy. Association between depression and quality of life, treatment responses, adverse effects and survival rate was considered positive at the significance level of p<0.05. Pearson and Spearman correlation coefficient, t-test and other statistical analysis were performed using the SPSS software version 13.0 for Windows. Results: In total, 126 lung cancer patients were evaluated, 38% had a diagnosis of depression. The presence of depression was associated with reduced quality of life, increased progression of disease, nausea and fatigue and reduced survival rate by nearly 90 days on follow-up. Therefore, depression significantly predicted worse survival (P=0.009).In addition, the chemotherapy DC regimen did not appear to improve the quality of life in depressed patients (SDS 94.96±18.14 before chemotherapy vs. SDS 100.04±16.61 after therapy, P=0.155). In a secondary analysis, there was a positive relationship between depression and nausea and fatigue but there was no significant difference in hematologic toxicities between the depression and non-depression groups. Conclusion: Depression was associated with worse survival in patients with newly diagnosed NSCLC. Also, the chemotherapy DC regimen did not improve quality of life in depressed patients and the data do not support the hypothesis that treatment responses of NSCLC patients with depression mediated the observed survival benefit from the DC regimen. There were more cases of progressed disease in the depressed group. Findings suggest that NSCLC patients with depression are at increased risk for decline in HR-QOL and survival rate during chemotherapy than patients without depression.

Abstract
PUVA-SP DCs are immature dendritic cells (imDCs) that have taken up donor splenic lymphocytes treated with 8-methoxypsoralen and ultraviolet A light (PUVA-SPs). Phagocytosis of donor PUVA-SPs does not stimulate phenotype maturation of recipient imDCs, and infusion of PUVA-SP DCs can induce CD4(+)CD25(high)Foxp3(+) regulatory T cells (Treg). However, the regulatory effect of PUVA-SP DCs on B cells is poorly understood. In this study, we compared PUVA-SP DCs with imDCs in terms of lipopolysaccharide (LPS) responsiveness and flow cytometric analysis of interleukin (IL) 10 expression in splenic CD19(+)B cells. Our results demonstrate that PUVA-SP DCs can suppress subsequent LPS-induced DC maturation and that infusion of PUVA-SP DCs, in the absence of an immunosuppressant, significantly promotes skin allograft survival. This effect was associated with up-regulation of circulating regulatory B cells exhibiting preferential IL-10 secretion. Our results suggest that effective treatments involving infusion of PUVA-SP DCs is likely related to the modulation not only of T-cell and Treg functions but also of B-cell and regulatory B-cell (Breg) functions.

Abstract
Plant polyphenols, such as hydrolysable tannins, are present in the human diet and known to exhibit anti-diabetic and anti-obesity activity. We previously reported that the representative hydrolysable tannin compound α-penta-galloyl-glucose (α-PGG) is a small molecule insulin mimetic that, like insulin, binds to insulin receptor (IR) and activates the IR-Akt-GLUT4 signaling pathway to trigger glucose transport and reduce blood glucose levels in db/db and ob/ob diabetic mice. However, its effects on adipogenesis and lipid metabolism were not known. In this study, high fat diet (HFD)-induced diabetic and obese mice were treated with α-PGG to determine its effects on blood glucose and triglycerides. 3T3-L1 preadipocytes were used as a cell model for identifying the anti-adipogenic activity of α-PGG at molecular and cellular levels as a first step in elucidating the mechanism of action of the compound. In vivo, oral administration of α-PGG significantly reduced levels of blood glucose, triglyceride, and insulin in HFD-induced diabetic/obese mice (P<0.05). In vitro, α-PGG inhibited the differentiation of 3T3-L1 preadipocytes into mature adipocytes. α-PGG suppressed the expression of positive adipogenic factors PPARγ C/EBPα and mTOR and augmented the negative adipogenic factor Pref-1. Furthermore, α-PGG induced upregulation of p21 and G1 phase cell cycle arrest. In contrast, adipogenic signaling pathways mediated by insulin, the cAMP response element binding protein (CREB) and glucocorticoid receptor (GR), were not inhibited. RNAi knockdown of p21 led to a 4-fold increase in triglyceride level in 3T3-L1 preadipocytes treated with MDI and α-PGG compared to regular preadipocytes. These results indicate, for the first time, that α-PGG is blood triglyceride- and glucose-lowering in HFD-induced obese and diabetic mice. It selectively inhibited some but not all major adipogenic pathways as well as the mTOR-p21-mediated cell cycle regulatory pathway. It is very likely that these apparently diverse but coordinated activities together inhibited adipogenesis. These results expand our knowledge on how PGG works in adipocytes and further confirm that α-PGG functions as an orally-deliverable natural insulin mimetic with adipogenetic modulatory functions.

Abstract
Emerging evidences indicate that placenta plays a critical role in gestational diabetes mellitus (GDM). DNA methylation could be associated with altered placental development and functions. This study is to uncover the genome-wide DNA methylation patterns in this disorder. DNA methylation was measured at >385,000 CpG sites using methylated DNA immunoprecipitation (MeDIP) and a huamn CpG island plus promoter microarray. We totally identified 6,641 differentially methylated regions (DMRs) targeting 3,320 genes, of which 2,729 DMRs targeting 1,399 genes, showed significant hypermethylation in GDM relative to the controls, whereas 3,912 DMRs targeting 1,970 genes showed significant hypomethylation. Functional analysis divided these genes into different functional networks, which mainly involved in the pathways of cell growth and death regulation, immune and inflammatory response and nervous system development. In addition, the methylation profiles and expressions of 4 loci (RBP4, GLUT3, Resistin and PPARα) were validated by BSP for their higher log2 ratio and potential functions with energy metabolism. This study demonstrates aberrant patterns of DNA methylation in GDM which may be involved in the pathophysiology of GDM and reflect the fetal development. Future work will assess the potential prognostic and therapeutic value for these findings in GDM.

Abstract
AIM OF THE STUDY Celastrus orbiculatus has been used as a folk medicine in China for the treatment of many diseases. In the laboratory, the ethyl acetate extract of Celastrus orbiculatus (COE) displays a wide range of anticancer functions. However, the inhibition of the metastasis mechanism of COE in gastric cancer cells has not been investigated so far. The present study was undertaken to determine if the antimetastatic effects of COE were involved in inhibition of the epithelial-mesenchymal transition (EMT) of human gastric adenocarcinoma SGC-7901 cells. METHODS The adhesion, invasion, and migration of SGC-7901 cells were determined by COE treatment in vitro, using Matrigel-coated plate, transwell membrane chamber, and wound healing models, respectively. In vivo, the growth-inhibiting and antimetastatic effects of COE on the nude mice model of gastric cancer were tested and the mechanisms were explored. The expression of EMT markers and nuclear factor κB (NF-κB)/Snail signaling pathway were evaluated by using western blotting and immunohistochemistry. RESULTS Treatment with COE dose-dependently inhibited the proliferation, adhesion, invasion, and migration of SGC-7901 cells in vitro, which was realized by enhancing the expression of E-cadherin and reducing N-cadherin and vimentin expression. Moreover, COE suppressed the activation of NF-κB/Snail signaling pathway induced by tumor necrosis factor-α. In addition, COE effectively suppressed tumor growth and metastasis in the nude mice model due to reduced expression of N-cadherin, vimentin, NF-κB p65, and Snail and increased expression of E-cadherin in the tumor tissues. CONCLUSION Our findings provided new evidence that COE is an effective inhibitor of metastatic potential of SGC-7901 cells through suppression of EMT and NF-κB/Snail signal pathway. Based on these findings, COE may be considered a novel anticancer agent for the treatment of metastasis in gastric cancer.
