Abstract
AIM We design a feasibility study to obtain a set of metabolic-hemodynamic habitats for tackling tumor spatial metabolic patterns with hemodynamic information. MATERIALS AND METHODS Preoperative data from 69 high-grade gliomas (HGG) patients with subsequent histologic confirmation of HGG were prospectively collected (January 2016 to March 2020) after concurrent chemoradiotherapy (CCRT). Four vascular habitats were automatically segmented by multiparametric magnetic resonance imaging (MRI). The metabolic information, either at enhancing or edema tumor regions, was obtained by two neuroradiologists. The relative habitat volumes were used for weight estimation procedures for computing the coefficients of a linear regression model using weighted least squares (WLS) for metabolite semiquantifications (i.e. the Cho/NAA ratio and the Cho/Cr ratio) at vascular habitats. Multivariate Cox proportional hazard regression analyses are used to obtain the odds ratio (OR) and develop a nomogram using weighted estimators corresponding to each covariate derived from Cox regression coefficients. RESULTS There was a strongly correlation between perfusion indexes and the Cho/Cr ratio (rCBV, r=0.71) or Cho/NAA ratio (rCBV, r=0.66) at high-angiogenic enhancing tumor habitats (HAT) habitat. Compared isocitrate dehydrogenase (IDH) mutation to their wild type, the IDH wild type had significantly decreased Cho/Cr ratio (IDH mutation: Cho/Cr ratio = 2.44 ± 0.33, IDH wildtype: Cho/Cr ratio = 2.66 ± 0.36, p=0.02) and Cho/NAA ratio (IDH mutation: Cho/Cr ratio = 4.59 ± 0.61, IDH wildtype: Cho/Cr ratio = 4.99 ± 0.66, p=0.022) at the HAT. The C-index for the median progression-free survival (PFS) prediction was 0.769 for the Cho/NAA nomogram and 0.747 for the Cho/Cr nomogram through 1000 bootstrapping validation. CONCLUSIONS Our findings suggest that spatial metabolism combined with hemodynamic heterogeneity is associated with individual PFS to HGG patients post-CCRT.

Abstract
BACKGROUND Recently, the importance of the interactions between liver cancer cells and fibroblasts has been increasingly recognized; however, many details remain to be explored. METHODS In this work, we first studied their intercellular interactions using conditioned medium from mouse embryonic fibroblasts (MEFs), then through a previously established coculture model. RESULTS Culturing in a conditioned medium from MEFs could significantly increase the growth, migration, and invasion of liver cancer cells. The coculture model further demonstrated that a positive feedback loop was formed between transforming growth factor-β (TGF-β) from HepG2 cells and mHGF (mouse hepatocyte growth factor) from MEFs during coculture. In this feedback loop, c-Met expression in HepG2 cells was significantly increased, and its downstream signaling pathways, such as Src/FAK, PI3K/AKT, and RAF/MEK/ERK, were activated. Moreover, the proportion of activated MEFs was also increased. More importantly, the growth-promoting effects caused by the interaction of these two cell types were validated in vitro by a 3D spheroid growth assay and in vivo by a xenograft mouse model. CONCLUSION Collectively, these findings provide valuable insights into the interactions between fibroblasts and liver cancer cells, which may have therapeutic implications for the treatment of liver cancer.

Abstract
In order to solve the problem that the accuracy of approximate position and approximate time information is limited by the traditional auxiliary positioning algorithm, this paper analyzes the problem that the calculation amount may increase and fail when these auxiliary information exceeds the precision requirement range and puts forward a positioning algorithm based on one-way fuzzy time assistance that is suitable for the positioning solution of GNSS satellite navigation receivers under the condition of fuzzy time information, such as the rotation condition. Methods using the reference information in the ephemeris information, the relatively accurate approximate time information can be reasonably searched and verified so as to achieve the effect of obtaining the positioning result with less calculation. The experimental results show that this method can accurately calculate the exact position even if there is an error in the approximate position information under the condition of one-way time assistance, which not only solves the problem that it cannot be positioned under the conditions of rotation but also does not increase the additional calculation amount and has practical engineering value.

Abstract
When cancer cells enter the bloodstream, they can interact with platelets to acquire stronger survival and metastatic abilities. To elucidate the underlying mechanisms, we cocultured metastatic melanoma and triple-negative breast cancer cells with species-homologous platelets. We found that cocultured cancer cells displayed higher viabilities in circulation, stronger capacities for cell migration, invasion, and colony formation in vitro, and more tumorigenesis and metastasis in mice. RNA sequencing analysis revealed that the level of serpin family E member 1 (SERPINE1) was significantly upregulated in cocultured cancer cells. Knockdown of SERPINE1 reversed the coculture-elevated survival and metastatic phenotypes of cancer cells. Mechanistic studies indicated that coculture with platelets activated the TGFβ/Smad pathway to induce SERPINE1 expression in cancer cells, which encodes plasminogen activator inhibitor 1 (PAI-1). PAI-1 then activated PI3K to increase the phosphorylation of AKTThr308 and Bad to elevate Bcl-2, which enhanced cell survival in circulation. Moreover, higher levels of PAI-1 were detected in metastatic tumors from melanoma and triple-negative breast cancer patients than in normal tissues, and high levels of PAI-1 were associated with a shorter overall survival time and worse disease progression in breast cancer. PAI-1 may act as a potential biomarker for detecting and treating metastatic tumor cells.

Abstract
Objective: To understand the performance of pulmonary function tests in people aged ≥40 years and its changes in China, and provide evidence for the evaluation of the effect of chronic obstructive pulmonary disease (COPD) prevention and control in China. Methods: The subjects of the survey were from COPD surveillance during 2014-2015 and during 2019-2020, which covered 31 provinces (autonomous regions and municipalities) in China. The survey used multi-stage stratified cluster random sampling method, the trained investigators conducted face-to-face interview to know whether subjects had previous pulmonary function testing or not. Complex sampling weighting was used to estimate the rate of pulmonary function testing in people aged ≥40 years, and the pulmonary function testing rates of the two COPD surveillance periods were compared. Results: A total of 148 427 persons were included in the analysis, including 74 591 persons during 2014-2015 and 73 836 persons during 2019-2020. In 2019-2020, the pulmonary function testing rate in Chinese residents aged ≥40 years was 6.7% (95%CI: 5.2%-8.2%), the rate in men (8.1%, 95%CI: 6.7%-9.6%) was higher than that in women (5.4%, 95%CI: 3.7%- 7.0%), and the rate in urban residents (8.3%, 95%CI: 6.1%-10.5%) was higher than that in rural residents (4.4%, 95%CI: 3.8%-5.1%). The rate of pulmonary function testing increased with the increase of education level. During 2019-2020, the residents with history of chronic respiratory diseases had the highest rate of pulmonary function testing (21.2%, 95%CI: 16.8%-25.7%), followed by the residents with respiratory symptoms (15.1%, 95%CI: 11.8%-18.4%) , the pulmonary function testing rate in those who knew the name of chronic respiratory disease was higher than that in those who did not knew the name of respiratory disease, and the pulmonary function testing rate in former smokers was higher than that in current smokers and non-smokers. Those exposed to occupational dust and/or harmful gases had a higher rate of pulmonary function testing compared with those who were not exposed, and those who used polluted fuels indoors had a lower rate of pulmonary function testing than those who did not use polluted fuels indoors (all P<0.05). Compared with 2014-2015, the pulmonary function testing rate in residents aged ≥40 years in China increased by 1.9 percentage points during 2019-2020, and the rate of pulmonary function testing in groups with different characteristics all increased, and the rates of pulmonary function testing increased by 7.4 percentage points and 7.1 percentage points in residents with respiratory symptoms and in those with history of chronic respiratory diseases (all P<0.05). Conclusions: Compared with 2014-2015, the rate of pulmonary function testing increased in China during 2019-2020 and the increase in residents with history of chronic respiratory diseases and respiratory symptoms was relatively obvious, but the overall pulmonary function testing rate was still at a low level. Effective measures should be taken to further increase the rate of pulmonary function testing.

Abstract
Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

Abstract
Hepatocellular carcinoma (HCC) progression is closely related to pathological fibrosis, which involves heterotypic intercellular interactions (HIIs) between liver cancer cells and fibroblasts. Here, we studied them in a direct coculture model, and identified fibronectin from fibroblasts and integrin-α5β1 from liver cancer cells as the primary responsible molecules utilizing CRISPR/Cas9 gene-editing technology. Coculture led to the formation of 3D multilayer microstructures, and obvious fibronectin remodeling was caused by upregulated integrin-α5β1, which greatly promoted cell growth in 3D microstructures. Integrin-α5 was more sensitive and specific than integrin-β1 in this process. Subsequent mechanistic exploration revealed the activation of integrin-Src-FAK, AKT and ERK signaling pathways. Importantly, the growth-promoting effect of HIIs was verified in a xenograft tumor model, in which more blood vessels were observed in bigger tumors derived from the coculture group than that derived from monocultured groups. Hence, we conducted triculture by introducing human umbilical vein endothelial cells, which aligned to and differentiated along multilayer microstructures in an integrin-α5β1 dependent manner. Furthermore, fibronectin, integrin-α5, and integrin-β1 were upregulated in 52 HCC tumors, and fibronectin was related to microvascular invasion. Our findings identify fibronectin, integrin-α5, and integrin-β1 as tumor microenvironment-related targets and provide a basis for combination targeted therapeutic strategies for future HCC treatment.

Abstract
To study how cancer cells can withstand fluid shear stress (SS), we isolated SS-resistant breast and lung cancer cells using a microfluidic circulatory system. These SS-resistant cells showed higher abilities to form clusters, survive in circulation, and metastasize in mice. These SS-resistant cells expressed 4.2- to 5.3-fold more desmocollin-2 (DSC2) and plakophilin-1 (PKP1) proteins. The high expression of DSC2 and PKP1 facilitated cancer cells to form clusters in circulation, and also activated PI3K/AKT/Bcl-2–mediated pathway to increase cell survival. The high levels of DSC2 and PKP1 are also important for maintaining high expression of vimentin, which stimulates fibronectin/integrin β1/FAK/Src/MEK/ERK/ZEB1–mediated metastasis. Moreover, higher levels of DSC2 and PKP1 were detected in tumor samples from patients with breast and lung cancer, and their high expression was correlated with lower overall survival and worse disease progression. DSC2 and PKP1 may serve as new biomarkers for detecting and targeting metastatic circulating tumor cells.

Abstract
BACKGROUND Gliomas are the most malignant and aggressive form of brain tumors, and account for the majority of brain cancer related deaths. Previous studies have reported that SUB1 serves as a novel RBP, which is highly expressed in tumors. AIM In our research, we aimed at exploring the regulatory mechanism of SUB1 in glioma cells. METHODS RT-qPCR was conducted to measure the expression of SUB1, HSP90β and MYC in glioma cells in U87 cell. Cell function tests were conducted to identify how the ectopic SUB1 expression influenced the proliferation and migration of glioma cells. Also, functional assays and mechanism experiments were carried out to figure out the relationship among circVCAN, SUB1 and MYC/HSP90β. RESULTS SUB1 expression was up-regulated in glioma cells. The inhibition of SUB1 expression suppressed the proliferation and migration of glioma cells, while the up-regulation of that accelerated the proliferation and migration of glioma cells. CircVCAN could up-regulate the expression of MYC/HSP90β by recruiting SUB1, thereby promoting glioma progression. CONCLUSION SUB1 plays a significant role in the survival and migration of glioma cells.

Abstract
Glioma is a common invasive cancer with unfavorable prognosis in patients. Long non-coding RNAs (lncRNAs) exert significant functions in carcinogenesis of various cancers including glioma. Among them, long intergenic non-coding RNA 668 (LINC00668) was reported to function as oncogene in various cancers, but its molecular mechanism in glioma has not been thoroughly researched. Our current study aimed to investigate the role and molecular mechanism of LINC00668 in glioma cells. We initially found out that LINC00668 was up-regulated in glioma cells. Through a series of function assays, LINC00668 was verified to facilitate cell proliferation and inhibit apoptosis in glioma. Then, by means of online databases, RNA pull down assay and RIP assay, we verified the binding relation between LINC00668 and miR-518c-3p. Also, the next function assays exposed that miR-518c-3p was the tumor suppressor in glioma cells. Similarly, SOCS5 (suppressor of cytokine signaling 5) was found to bind with miR-518c-3p, which repressed glioma tumorigenesis by targeting SOCS5. Moreover, rescue assays manifested that LINC00668 modulated expression of SOCS5 in a miR-518c-3p-dependent way and further regulated glioma tumorigenesis. Overall, LINC00668 modulates SOCS5 expression through competitively sponging miR-518c-3p to facilitate glioma cell proliferation.

Abstract
BACKGROUND Signal regulatory protein β1 (SIRPB1) is a signal regulatory protein member of the immunoglobulin superfamily and is capable of modulating receptor tyrosine kinase-coupled signaling. Copy number variations at the SIRPB1 locus were previously reported to associate with prostate cancer aggressiveness in patients, however, the role of SIRPB1 in prostate carcinogenesis is unknown. METHODS Fluorescence in situ hybridization and laser-capture microdissection coupled with quantitative polymerase chain reaction was utilized to determine SIRPB1 gene amplification and messenger RNA expression in prostate cancer specimens. The effect of knockdown of SIRPB1 by RNA interference in PC3 prostate cancer cells on cell growth in colony formation assays and cell mobility in wound-healing, transwell assays, and cell cycle analysis was determined. Overexpression of SIPRB1 in C4-2 prostate cancer cells on cell migration, invasion, colony formation and cell cycle progression and tumor take rate in xenografts was also determined. Western blot assay of potential downstream SIRPB1 pathways was also performed. RESULTS SIRPB1 gene amplification was detected in up to 37.5% of prostate cancer specimens based on in silico analysis of several publicly available datasets. SIRPB1 gene amplification and overexpression were detected in prostate cancer specimens. The knockdown of SIRPB1 significantly suppressed cell growth in colony formation assays and cell mobility. SIRPB1 knockdown also induced cell cycle arrest during the G0 /G1 phase and enhancement of apoptosis. Conversely, overexpression of SIPRB1 in C4-2 prostate cancer cells significantly enhanced cell migration, invasion, colony formation, and cell cycle progression and increased C4-2 xenograft tumor take rate in nude mice. Finally, this study presented evidence for SIRPB1 regulation of Akt phosphorylation and showed that Akt inhibition could abolish SIRPB1 stimulation of prostate cancer cell proliferation. CONCLUSIONS These results suggest that SIRPB1 is a potential oncogene capable of activating Akt signaling to stimulate prostate cancer proliferation and could be a biomarker for patients at risk of developing aggressive prostate cancer.

Abstract
OBJECTIVES Later-life cognitive impairment is an important health issue; however, little is known about the condition among diverse groups such as immigrants. This study aims to examine whether the healthy immigrant effect exists for verbal fluency, an indicator of cognitive functioning, among anglophone middle-aged and older adults in Canada. METHODS Using from the baseline data of the Canadian Longitudinal Study on Aging (CLSA), multiple linear regression was employed to compare associations among immigrants (recent and long-term) and Canadian-born residents without dementia for two verbal fluency tests, the Controlled Oral Word Association Test (COWAT) and the Animal Fluency (AF) task. Covariates included socioeconomic, physical health, and dietary intake. RESULTS Of 8,574 anglophone participants (85.7% Canada-born, 74.8% aged 45-65 years, 81.8% married, 81.9% with a post-secondary degree), long-term immigrants (settled in Canada >20 years) performed significantly better than Canadian-born residents for the COWAT (42.8 vs 40.9) but not the AF task (22.4 vs 22.4). Results of the multivariable adjusted regression analyses showed that long-term immigrants performed better than Canadian-born peers in both the COWAT (B=1.57, 95% CI: 0.80-2.34) and the AF test (B=0.57, 95% CI: 0.19-0.95), but this advantage was not observed among recent immigrants. Other factors associated with low verbal fluency performance included being single, socioeconomically disadvantaged, having hypertension, excess body fat, and consuming low amounts of pulses/nuts or fruit/vegetables. CONCLUSIONS Long-term immigrants had higher verbal fluency test scores than their Canadian-born counterparts. Immigration status, social, health and nutritional factors are important considerations for possible intervention and prevention strategies for cognitive impairment.

Abstract
The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is a polyphagous insect that attacks tens of plant and causes substantial economic loss. Insect chitinases are required to remove the old cuticle to allow for continued growth and development. Though insect chitinases have been well studied in tens of insects, their functions in mealybug are still not addressed. Here, we sequenced the transcriptomes of adult males and females, from which eight chitinase genes were identified. We then used the method of rapid amplification of cDNA ends to amplify their full length. Phylogenetic analysis indicated that these genes clustered into five subgroups. Among which, group II PsCht2 had the longest transcript and was highly expressed at second instar nymph. PsCht10, PsCht3-3 and PsIDGF were highly expressed in the adult females, whereas PsCht4 and PsCht4-1 were significantly expressed at the male pupa and adult male. Next, we knocked down all eight chitinase genes by feeding the double-stranded RNA. Knockdown of PsCht4 or PsCht4-1 led to the failure of moult and, silencing PsCht5 resulted in pupation defect, while silencing PsCht10 led to small body size, suggesting these genes have essential roles in development and can be used as a potential target for pest control.

Abstract
Objective: This study was designed to identify the relative factors, bacteriological profile and their antibiotic susceptibility pattern of neonatal sepsis. Methods: A retrospective survey was conducted on the clinical information, pathogen identification and antibiotic sensitivity results of 425 newborns with neonatal sepsis admitted to Nanjing Maternity and Child Health Care Hospital from 2010 to 2017. Of the 425 positive blood-cultures, 148 (34.82%) were early-onset neonatal sepsis (EOS) and 277 (65.18%) were late-onset neonatal sepsis (LOS). Clinical information and pathogen identification were compared between EOS and LOS. Antibiotic sensitivity of gram negative organisms (G(-)) and gram positive organisms (G(+)) were also detected. Results: The rates of premature delivery (78.70%, n=218), low birth weights (67.15%, n=186) and cesarean delivery (59.57%, n=165) were significantly increased in LOS (P<0.05) compared with those rates in EOS, which were 41.89% (n=62), 37.84% (n=56) and 46.62% (n=69). Parturients fever (18.24%, n=27) and meconium like amniotic fluid (25.68%, n=38) were significantly increased in EOS (P<0.05) compared with those rates in LOS, which were 7.94% (n=22) and 5.42% (n=15). Among the identified pathogen, the incidence of G(-) and G(+) bacteria were 216 (50.83%) and 201 (47.29%) respectively, and the rest was Candida glabrata (1.88%, n=8). Escherichia coli 68 (16.00%) was the predominant isolate followed by Klebsiella pneumoniae (13.18%, n=56). The detection rate of Hemolytic staphylococcus (10.81%, n=16) was significantly increased in EOS (P<0.001) compared with LOS (1.44%, n=4). However, the incidence of Klebsiella pneumonia (5.88%, n=44) was higher in LOS (P=0.024) compared with EOS (8.11%, n=12). Most of the gram positive isolates exhibited high resistance to penicillin (90.32%-100.00%) and cephalosporin group antibiotics (25.00%-100.00%). Similarly, the majority of the gram negative isolates showed higher resistance to ampicillin (83.33%-100.00%), but susceptible to aminoglycosides (0-11.76%), quinolones (0-17.65%) and β-lactams (0-5.88%). Conclusion: Among the study population, the percent of preterm, low birth weight and cesarean section were higher in LOS while parturients fever and meconium-like amniotic fluid were higher in EOS. The pathogens with the highest detection rate were Escherichia coli and Klebsiella pneumoniae. The results of antibiotic susceptibility test showed that common pathogens had high resistance to commonly used antibacterial drugs.

Abstract
Chemoresistance, in various types of cancer including prostate cancer (PCa), is one of the major challenges in cancer therapy. Others and our lab have reported that the epithelial-to-mesenchymal transition (EMT) plays critical roles in development of chemoresistance and metastasis. The calcium-sensing receptor (CaSR) plays important roles in maintenance of calcium homeostasis and altered CaSR expression, and functional changes are involved in certain diseases, including tumorigenesis and its development. However, the mechanism of CaSR in PCa chemoresistance remains unclear. In current study, the CaSR expression level was detected in parental PC3 and DU145 cells and their chemoresistant PC3-TxR and DU145-TxR cells. We found the CaSR was highly expressed in chemoresistant PC3-TxR and DU145-TxR cells. Then by using siRNA technique, CaSR expression was transiently knocked down in chemoresistant cells. The tumor cell migration, invasion, and colony formation were evaluated by wound healing, transwell, and colony formation assays, respectively. The drug sensitivity was evaluated using MTS assay. We observed that the abilities of tumor cell migration and invasion were significantly diminished in CaSR knockdown PC3-TxR and DU145-TxR cells. The ability of colony formation was also reduced. Interestingly, the sensitivity to paclitaxel was reactivated in CaSR knockdown PC3-TxR and DU145-TxR cells. We finally observed that E-cadherin expression was increased in CaSR knockdown chemoresistant cells, and Snail, Vimentin and β-catenin were decreased; these results are consistent with EMT phenotypic alterations. Taken together, we conclude that downregulation of CaSR enhances MET-mediated prostate cancer chemosensitivity.

Abstract
Abstract
Overexpression of the tumor-derived monocyte chemotactic protein-1 (MCP-1) has been suggested to partially promote prostate cancer bone metastasis, but the function for host-derived MCP-1 in these processes is not well established. To understand the function of host-derived MCP-1 on bone metastasis, we developed a mouse model using intracardiac injection and in vivo selection to obtain tumor cell subpopulations with a higher propensity for bone metastasis. Here, we found that a loss of host MCP-1 (MCP-1 knockout) retarded tumor growth in bone and prolonged survival of mice by intracardiac injection of tumor cells in vivo. Moreover, a decrease in osteolytic bone lesion was observed in MCP-1 knockout mice by bone density analysis, as compared to wild-type control. Systemically, MCP-1 deficiency inhibited the proportion of PMN-and M-MDSC populations with immunosuppressive function. Together, this study indicates that the dysregulated immunity resulting from a loss of host MCP-1 signaling is sufficient to drive PCa bone metastasis, and provides a new perspective for targeting the endogenous MCP-1 pathway as an antimetastatic strategy.

Abstract
Abstract
Metastasis is the major cause of treatment failure in various malignancies, including prostate cancer (PCa). Accumulating data has suggested that primary cancer cells prefer to spread to certain distant organs. To explore the mechanisms of different cancer cells preferentially metastasizing to certain organs, we established a prostate cancer lung metastasis model. Murine prostate cancer cells (RM1), which labeled with luciferase, were used in this study. RM1 cells were injected into left tibia of mouse (C57BL/6J), and monitored the tumor growth and metastasis every week by Bioluminescence Imaging. The mice would be sacrificed when metastatic tumor appeared in multi-organs. We isolated the lung metastatic tumor, made single cell suspension and amplified. The lung metastatic tumor cells were specifically metastasized to lung when the tumor cells were injected intratibially again. After several cycles we obtained highly lung metastatic tumor cells, named RM1-LM cells. Further, we investigated property and function changes in RM1-LM cells compared to parental cells (RM1) using in vitro assays. We firstly found the highly lung metastatic tumor cells showed more mesenchymal properties. Western blot results showed that hallmarks of EMT including E-cadherin, vimentin, snail, and ZO-1 were altered significantly in RM1-LM cells. Then, we observed that the highly lung metastatic tumor cells exhibited increased proliferative, colony formation, migratory and invasive abilities. Mechanistic analyses indicated that prostate cancer organ-specific metastasis mediated by the activation of GSK-3β/β-catenin pathway. The current study may provide potential therapeutic targets and diagnostic biomarkers of PCa metastasis.

Abstract
Abstract
Signal-regulatory-protein beta 1(SIRPB1) is a member of the signal-regulatory-protein (SIRP) family that belongs to the immunoglobulin superfamily and is capable of modulating receptor tyrosine kinase-coupled signaling. The copy-number variations (CNV) at the SIRPB1 locus were associated with aggressiveness of prostate cancer in patients. To test if SIRPB1 could affect prostate cancer development and progression, we investigated the potential role and mechanisms of SIRPB1 action in prostate cancer cell lines in vitro and in xenograft tumors. Knockdown of SIRPRB1 by RNA interference resulted in significant suppression of cell colony formation, cell mobility, cell migration, and invasion. The knockdown also induced cell cycle arrest during the G0/G1 phase and a remarkable enhancement of apoptosis in PC3 prostate cancer cells. In contrast, overexpression of SIPRB1 significantly induced cell migration, invasion, colony formation and cell cycle in C4-2 prostate cancer cells. Furthermore, overexpression of SIRPB1 in C4-2 cell model enhanced its tumor take rate in nude mice. Also, SIRPB1 mRNA expression was increased in up to 39% of the prostate cancer specimens based on in silico analysis of several public databases. These results suggest that SIRPB1 is a potential oncogene in the prostate and could be used as a biomarker to identify patients at risk of developing aggressive prostate cancer.

Abstract
Objective: To explore prognostic factors of acute paraquat poisoning (APP) , analyze the correlation between base excess (BE) and plasma concentration of paraquat (C-PQ) and discuss BE level in evalua-tion of prognosis of acute paraquat poisoning patients. Methods: We retrospectively selected 84 APP patients who admitted to Emergency Intensive Care Unit (EICU) of our hospital from 2009.9.1 to 2015.8.31.Clinical data from 84 APP patients were analyzed. BE、C-PQ、time of gastric lavagesince ingestion、time of hemoperfusion since ingestion、severity index of paraquat poisoning (SIPP) 、white blood cell (WBC) 、percentage of neutrophils (N%) 、hemoglobin (HB) 、creatinine (Cr) 、alanine aminotransferase (ALT) 、aspartate aminotransferase (AST) 、partial pressure of oxygen (PaO(2)) 、partial pressure of carbon dioxide (PaCO(2)) and other laboratory parameters were measured. A total of 41 patients in non-survivors died during the 30 days after admission and 43 patients in survivors survived during the 30 days. The factors of prognosis in paraquat poisoining and the role of BE in evalu-ating prognosis was analyzed, as well as the correlation between BE and C-PQ. Results: 1.Logistic regression analyses showed BE、C-PQ、ALT、AST、Cr was of prognostic significance[odds ratio (OR) of BE: 0.511, 95%CI 0.267, 0.978; C-PQ:-=0.999, 95%CI 0.999, 1.000; both P<0.05] ; 2.The area under the receiver operating characteristic curve (ROC curve) of BE、C-PQ and prognosis were 0.775、0.927 respectively, BE≤-1.7 mmol/L was the best cut-off value, the sensitivity、specificity for predicting were 82.9%、62.8%, the evaluation value was lower to C-PQ>3 273.935 ng/ml (AUC 0.927, 78.0%、95.3%) ; 3.BE negative correlated with C-PQ[-1.100 (-4.100, -0.200) , -5.900(-8.650, -2.500) , both P<0.05]. (r=-0.4, P<0.01). Conclusion: These results suggest that BE may be useful for the prediction of prognosis in PQ poisoning and BE negative correlated with C-PQ.

Abstract
We consider the model Zt = φ (0, k)+ φ(1, k)Zt–1 + at (k) whenever rk−1<Zt−1≦rk, 1≦k≦l, with r0 = –∞ and rl =∞. Here {φ (i, k); i = 0, 1; 1≦k≦l} is a sequence of real constants, not necessarily equal, and, for 1≦k≦l, {at(k), t≧1} is a sequence of i.i.d. random variables with mean 0 and with {at(k), t≧1} independent of {at(j), t≧1} for j ≠ k. Necessary and sufficient conditions on the constants {φ (i, k)} are given for the stationarity of the process. Least squares estimators of the model parameters are derived and, under mild regularity conditions, are shown to be strongly consistent and asymptotically normal.

Using Akaike's information criterion, we have presented an objective procedure for the determination of the order of an ergodic Markov chain with a finite number of states. The procedure exploits the asymptotic properties of the maximum likelihood ratio statistics and Kullback and Leibler's mean information for the discrimination between two distributions. Numerical illustrations are given, using data from Bartlett (1966), Good and Gover (1967) and some weather records.

Abstract
MUC13 is a transmembrane mucin glycoprotein that is over produced by many cancers, although its functions are not fully understood. Nuclear factor-κB (NF-κB) is a key transcription factor promoting cancer cell survival, but therapeutically targeting this pathway has proved difficult because NF-κB has pleiotropic functions. Here, we report that MUC13 prevents colorectal cancer cell death by promoting two distinct pathways of NF-kB activation, consequently upregulating BCL-XL. MUC13 promoted tumor necrosis factor (TNF)-induced NF-κB activation by interacting with TNFR1 and the E3 ligase, cIAP1, to increase ubiquitination of RIPK1. MUC13 also promoted genotoxin-induced NF-κB activation by increasing phosphorylation of ATM and SUMOylation of NF-κB essential modulator. Moreover, elevated expression of cytoplasmic MUC13 and NF-κB correlated with colorectal cancer progression and metastases. Our demonstration that MUC13 enhances NF-κB signaling in response to both TNF and DNA-damaging agents provides a new molecular target for specific inhibition of NF-κB activation. As proof of principle, silencing MUC13 sensitized colorectal cancer cells to killing by cytotoxic drugs and inflammatory signals and abolished chemotherapy-induced enrichment of CD133+ CD44+ cancer stem cells, slowed xenograft growth in mice, and synergized with 5-fluourouracil to induce tumor regression. Therefore, these data indicate that combining chemotherapy and MUC13 antagonism could improve the treatment of metastatic cancers.

Abstract
Chromosomal aberration mostly occurs in chromosomes 21, 18 and 13, with an incidence approximately 1 out of 160 live births in humans, therefore making prenatal diagnosis necessary in clinics. Current methods have drawbacks such as time consuming, high cost, complicated operations and low sensitivity. In this paper, a novel method for rapid and accurate prenatal diagnosis of aneuploidy is proposed based on pyrosequencing, which quantitatively detects the peak height ratio (PHR) of different bases of segmental duplication. A direct polymerase chain reaction (PCR) approach was undertaken, where a small volume of amniotic fluid was used as the starting material without DNA extraction. Single-stranded DNA was prepared from PCR products and subsequently analyzed using pyrosequencing. The PHR between target and reference chromosome of 2.2 for euploid and 3:2 for a trisomy fetus were used as reference. The reference intervals and z scores were calculated for discrimination of aneuploidy. A total of 132 samples were collected, within trisomy 21 (n = 11), trisomy 18 (n = 3), trisomy 13 (n = 2), and unaffected controls (n = 116). A set of six segmental duplications were chosen for analysis. This method had consistent results with karyotyping analysis, a correct diagnosis with 100% sensitivity and 99.9% specificity.

Abstract
Glioma is the most common malignant brain tumors with poor prognosis. The molecular events involved in the development and progression of glioma remain unclear. In this study, the expression levels of miR-302c-3p were examined in glioma tissues by qRT-PCR. The in vitro and in vivo functional effects of miR-302c-3p were examined further. Luciferase reporter assays were conducted to confirm the targeting associations. Results showed that the expression level of miR-302c-3p in glioma tissues was significantly lower than those in normal brain tissues (P < 0.001). The decreased expression of mi-302c-3p in glioma was positively associated with WHO grade (P < 0.001). Up-regulation of MTDH was also detected in glioma tumors compared with normal brain tissues (P = 0.0027) and is inversely correlated with miR-302c-3p expression (P = 0.003, R(2) = 0.4065). MTDH mRNA is a direct target of miR-302c-3p, whose ectopic expression decreases MTDH expression through binding to its 3'-untranslated region. Overexpression of miR-302c-3p results in a dramatic inhibition of glioma cells proliferation and invasion in vitro and in vivo. These data suggest that miR-302c-3p play a pivotal role in the progression of glioma by targeting MTDH and is a potential inhibitor in glioma treatment.

Abstract
AIM In this study, we aim to evaluate the association of risk factors including homocysteine (Hcy) with the severity and burden of coronary atherosclerotic plaques detected by computed tomography angiography (CTA). METHODS Six hundred fifty-nine subjects who underwent CTA for the assessment of coronary artery disease (CAD) were studied. All the subjects enrolled had no clinical cardiovascular disease symptoms. Logistic regression showed apart from age, hypertension, smoking, triglyceride, low-density lipoprotein (LDL) cholesterol, and total bilirubin, Hcy was an independently risk factor of the severity of coronary disease. And Hcy was also found an independent predictor for the presence of calcified plaque. When the participants were divided into 4 groups according to serum Hcy quartiles (Q1-Q4 groups), both the percentage of patients with >50% stenosis and the percentage of patients with calcified plaque were higher in Q4 compared to other groups. The OR of Hcy (>15 µmol/L) for >50% stenosis was 2.212 (95% CI=1.119 to 4.375, P=0.022) and the OR for Hcy (>15 µmol/L) for calcification was 1.668 (95% CI=1.030 to 2.699, P=0.037) respectively. CONCLUSION Our study shows Hcy is independently associated with both the severity and calcified plaque detected by CTA. Hcy may provide additional information about CAD in the subjects without clinical symptoms.

Abstract
BACKGROUND Previous research has shown that gastric acid suppression by antacid drugs can promote allergic reactions to acid-labile food proteins. No data are available about whether antacid drugs can promote drug hypersensitivity reactions. The most potent and longer lasting inhibition of gastric secretion is provided by proton pump inhibitors (PPIs). We hypothesized that gastric acid suppression by proton pump inhibitors could be causative of drug hypersensitivity reactions during hospitalization. OBJECTIVE To estimate the risk of developing drug hypersensitivity reactions during the hospitalization of patients treated with proton pump inhibitors, and other associated factors. METHODS A nested case-control in a retrospective cohort study of hospitalized patients from September 2008 to December 2010 (70 771 admissions) was conducted using the registry of cases of interconsultations to the Allergy Department (161 confirmed cases of drug hypersensitivity reactions). A total of 318 controls were matched by first drug suspected in the hypersensitivity reaction, time of admission, age, gender and hospitalization wards. RESULTS The relative risk of drug hypersensitivity reaction occurrence during hospitalization of patients treated with PPIs compared with those not treated in the period of study was significant (RR: 3.97; 95% CI: 1.97-8.29). After controlling for confounders in the nested case-control cohort, the use of PPIs persists as a predisposing factor (OR: 4.35; 95% CI: 2-9.45). Personal history of drug allergy and a long hospitalization time were other predisposing factors of drug hypersensitivity reactions (DHRs). The hazard that a DHR has occurred during PPI treatment was 3.7% per day. The hazard for immediate or accelerated reactions was 1.706 (P = 0.003) times that of delayed reactions. CONCLUSION AND CLINICAL RELEVANCE In hospitalized patients, the use of proton pump inhibitors was associated with a significant increase risk of drug hypersensitivity reactions along with a personal history of drug allergies and long hospitalization time.

Abstract
PURPOSE Controlling and eliminating lymphatic filariasis will require further research of preventative measures and implementation. Parasite is dependent on glycolysis for ATP production. The glycolytic enzyme glyceraldenyde-3-phosphate dehydrogenase (GAPDH) plays an important role in glycolysis and therefore is either a potential target for anti-parasite drug development or a vaccine candidate. Therefore, we tried to investigate the DNA vaccine-elicited immune responses in BALB/c mice. MATERIALS AND METHODS We cloned a gene encoding the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from periodic Brugia malayi into vector pcDNA3.1. Mice were injected at a dosage of 100 μg recombinant plasmid DNA with CpG intramuscular injection and immunized three times at 2-week intervals. pcDNA3.1 and normal saline were used as control. The tissue of muscles at the 4 weeks after the third injection was collected and target genes were detected using RT-PCR. The humoral responses elicited in mice by inoculation with the recombinant plasmid pcDNA3.1-BmGAPDH were detected using a standard ELISA. Two weeks after the third immunization, stimulation index (SI) was measured using the MTT method and the level of secreted IL-4 and INF-g were detected using ELISA. RESULTS Specific gene fragment coding GAPDH was amplified and the recombinant plasmid pcDNA3.1-BmGAPDH was constructed. Post-challenge sera from the mice immunized with the DNA vaccine had specific antibody titres of 1:1600 to 1:6400, and the highest titre was observed in the mice that were inoculated by pcDNA3.1-BmGAPDH/CpG at 6 weeks. At 4 weeks after immunization, the spleens of the mice were obviously enlarged. The proliferation of spleen T lymphocytes seen on the MTT assay was higher in the pcDNA3.1-BmGAPDH group than in the control group (P value <0.05). The levels of IL-4 and INF-γ in serums from the immunized mice were significantly higher than that of the control (P value <0.05). CONCLUSIONS We conclude that the recombinant eukaryotic plasmid pcDNA3.1-BmGAPDH could elicit humoral and cellular immune responses in mice.

Abstract
The synthesis of novel substituted gold(III) tetraarylporphyrins with aqueous solubility has been carried out. The analogs ClAuTPP(CH(3)Py(+)·I(-)), ClAuTCPPNa, ClAuTPPCO(2)Na, ClAuTSPPNa and ClAuTPPNH(2)·HCl were evaluated for their in vitro cytotoxic activity against sarcoma 180 mouse tumor and SGC-7901 human gastric cancer cell line panel. Compound ClAuTCPPNa exhibited significant growth inhibitory properties against sarcoma 180 mouse tumor and SGC-7901 human gastric cancer cell examined, and afforded IC(50) values <25 μM for 66.63% of the cell lines in the panel. Compound ClAuTPPNH(2)·HCl was an effective inhibitor of sarcoma 180 mouse tumor and SGC-7901 human gastric cancer cell growth, but generally less effective as a cytotoxic agent. Thus, the substituted gold(III) porphyrin ClAuTCPP-Na(+) and ClAuTPPNH(2)·HCl with aqueous solubility were regarded as useful lead compounds for further structural optimization.
