Abstract
Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is an immune-mediated inflammatory demyelinating disease of the central nervous system. This study aimed to delineate the clinical manifestations, imaging features, and long-term outcomes in Chinese patients with MOGAD and analyze the recurrence-associated factors. The phenotypic and neuroimaging characteristics of 15 Han Chinese patients with MOGAD were retrospectively analyzed. Demyelinating attacks, MOG antibodies in the cerebrospinal fluid/serum, response to immunotherapy, follow-up outcomes, and recurrence-associated factors were recorded. The median age at disease onset was 34 years (range, 4-65 years). The most common initial presentations included vision loss (10/15, 66.7%) and seizures (5/15, 33.3%). Serum MOG-Ab titers in 14/15 cases were higher than those in the cerebrospinal fluid and were detected in 3/6 relapsed patients. Brain magnetic resonance imaging during acute attacks showed lesions in 10/15 patients (66.7%), mostly in the cortex/subcortical white matter (5/15, 33.3%). Recurrence occurred in 6/15 patients (40.0%); in 4 patients, recurrence occurred shortly after immunotherapy discontinuation. Residual neurological deficits were present in 5/15 patients (33.3%), including visual impairment, incapacitation, cognitive impairment, and speech reduction. Optic neuritis was the most common clinical manifestation of MOGAD. magnetic resonance imaging findings were heterogeneous and the cerebral cortex/subcortical white matter was the most susceptible brain region. Although patients in the acute phase responded well to methylprednisolone pulse therapy, the long-term recurrence rate was high. Consistently detected serum MOG antibodies and inappropriate maintenance immunotherapy may be associated with recurrence, and residual neurological deficits should not be ignored.

Abstract
Introduction The emergence of the Omicron variant has seen changes in the clinical and radiological presentations of COVID-19 in pediatric patients. We sought to compare these features between patients infected in the early phase of the pandemic and those during the Omicron outbreak. Methods A retrospective study was conducted on 68 pediatric COVID-19 patients, of which 31 were infected with the original SARS-CoV-2 strain (original group) and 37 with the Omicron variant (Omicron group). Clinical symptoms and chest CT scans were examined to assess clinical characteristics, and the extent and severity of lung involvement. Results Pediatric COVID-19 patients predominantly had normal or mild chest CT findings. The Omicron group demonstrated a significantly reduced CT severity score than the original group. Ground-glass opacities were the prevalent radiological findings in both sets. The Omicron group presented with fewer symptoms, had milder clinical manifestations, and recovered faster than the original group. Discussion The clinical and radiological characteristics of pediatric COVID-19 patients have evolved with the advent of the Omicron variant. For children displaying severe symptoms warranting CT examinations, it is crucial to weigh the implications of ionizing radiation and employ customized scanning protocols and protective measures. This research offers insights into the shifting disease spectrum, aiding in the effective diagnosis and treatment of pediatric COVID-19 patients.

Abstract
Objective: Analysis of the characteristics of influenza epidemic in Anhui Province and quantification of the impact of different factors on influenza occurrence, providing scientific basis for better influenza prevention and control. Methods: Descriptive analysis and factor analysis were conducted on influenza-like illness (ILI) cases and RT-PCR results in Anhui Province from 2013 to 2021 using data from China's Influenza Monitoring Information System. Results: The percentage of influenza-like illness (ILI%) of sentinel hospitals in Anhui Province from April 1, 2013 to March 31, 2021 was 3.80% (1 209 142/31 779 987), showing an overall increasing trend, with a relatively high proportion in 2017-2018 at 4.30% (191 148/4 448 211). The proportion of ILI cases in infants and young children aged 0-4 years was a relatively high at 54.14% (654 676/1 209 142), and the highest ILI% was observed in Fuyang City, Anhui Province (6.25%, 236 863/3 788 863). Laboratory monitoring results showed that the positive rate of ILI cases in sentinel hospitals in 8 influenza monitoring years was 16.38% (34 868/212 912), showing an increasing trend year by year, with a relatively proportion in 2017-2018 at 26.19% (6 936/26 488). The detection rate of school-age children aged 5-14 years was a relativelyhigh at 28.81% (13 869/48 144), and the positive rate was a relatively high in Wuhu City among the 16 cities, reaching 22.01% (2 693/122 237). Influenza activity showed a single peak in winter-spring and alternating double peaks in winter-spring and summer, with different subtypes alternating, and A (H3N2) was the dominant subtype in summer. The results of a multiple logistic regression model showed that the positive rate was higher in 2017-2018, among children aged 5-14 years, in winter, and in southern Anhui. Conclusions: Influenza epidemic in Anhui Province has a clear seasonal pattern, and the ILI% and detection rate have shown an upward trend from 2013 to 2021. Therefore, it is suggested to ensure vaccine supply before the winter-spring influenza season arrives, and to strengthen vaccine uptake and health education to avoid the risk of infection during the peak period of influenza.

Abstract
INTRODUCTION Lycium barbarum is an edible fruit widely used in herbal medicines and as a functional food. Polysaccharide is one of the most important active ingredients. Only L. barbarum grown in the Ningxia region of China are officially recognised as suitable for use in traditional Chinese medicine, but the systematic comparison of L. barbarum polysaccharide between Ningxia and the other growing regions of China has been rarely reported. OBJECTIVE To compare the difference of L. barbarum polysaccharide from different grown regions of China. METHODS A chemical fingerprint of L. barbarum polysaccharide hydrolysates was established based on controlled acidolysis combined with hydrophilic interaction liquid chromatography-evaporative light scattering detection-electrospray ionisation-time-of-flight-mass spectrometry (HILIC-ELSD-ESI-TOF-MS). Then, it was employed for the comparison of L. barbarum samples from different geographical origins of China combined with chemometrics analysis. RESULTS Six monosaccharides [rhamnose (Rha), xylose (Xyl), arabinose (Ara), mannose (Man), glucose (Glu), galactose (Gal)] were qualitatively and quantitatively determined and four glycoconjugates were preliminarily identified from the hydrolysates. Content determination for the polysaccharide and monosaccharide indicated obvious geographical features. The HILIC-ELSD fingerprint combined with partial least squares-discriminant analysis (PLS-DA) was able to differentiate L. barbarum samples from Ningxia, Xinjiang, Gansu and Qinghai regions with 89.19% classification accuracy. Orthogonal projection to latent structure discriminant analysis (OPLS-DA) was able to differentiate between samples from Ningxia and those from the other three growing regions, polysaccharide and Ara were the potential chemical markers. CONCLUSIONS These findings form the basis of a reliable method to trace the region of origin of L. barbarum sample and thereby, improve the quality control of L. barbarum therapeutic polysaccharides.

Abstract
Background RNA adenosine modifications, which are primarily mediated by “writer” enzymes (RMWs), play a key role in epigenetic regulation in various biological processes, including tumorigenesis. However, the expression and prognostic role of these genes in osteosarcoma (OS) remain unclear. Methods Univariate and multivariate Cox analyses were used to construct the RMW signature for OS using Target datasets. RMW expression in OS tissue was detected by qPCR analysis. Xcell and GSVA were used to determine the relationship between RMWs and immune infiltration. The DGIdb and CMap databases were used for drug prediction. In vivo and in vitro experiments showed that strophanthidin elicited antitumor activity against OS. Results A 3-RMW (CSTF2, ADAR and WTAP) prognostic signature in OS was constructed using the Target dataset and verified using GEO datasets and 63 independent OS tissues via qPCR analysis. High-risk OS patients had poor overall survival, and the prognostic signature was an independent prognostic factor for OS. Functional studies showed that tumour-, metabolism-, cell cycle- and immune-related pathways were related to high risk. Next, we found that RMW-derived high-risk patients exhibited increased infiltration of M2 macrophages and cDCs. Furthermore, we predicted the potential drugs for OS using the DGIdb and CMap databases. In vivo and in vitro experiments showed that strophanthidin elicited antitumor activity against OS by repressing cell growth and inducing cell cycle arrest at the G1 phase. Conclusion The 3-RWM-based prognostic signature established in this study is a novel gene signature associated with immune infiltration, and strophanthidin was identified as a candidate therapy for OS by repressing OS cell growth and the cell cycle.

Abstract
The pandemic influenza A (H1N1) virus spread globally and posed one of the most serious global public health challenges. The traditional Chinese medicine is served as a complementary treatment strategy with vaccine immunization. Here, we demonstrated that the mixed polysaccharides (MPs) derived from shiitake mushroom, poriacocos, ginger, and tyangerine peel prevent the H1N1 virus infections in mice. MP pretreatment attenuated H1N1 virus-induced weight loss, clinical symptoms, and death. The lymphocytes detection results showed that the CD3+, CD19+, and CD25+ cell proportions were upregulated in thymus under MP pretreatment. Besides, MP pretreatment reduced the inflammatory cell infiltration and increased the cell proportions of CD19+, CD25+, and CD278+ in lung. However, MP treatment have no effective therapeutic effect after H1N1 virus challenge. The current study suggested that pretreatment with MPs could attenuate H1N1 virus-induced lung injury and upregulate humoral and cellular immune responses in nonimmunized mice.

Abstract
Ulcerative colitis (UC) is an incurable chronic inflammation of the enteric tract. The aim of this study was to investigate the protective effects of arabinogalactan from Lycium barbarum on DSS-induced chronic colitis. A homogeneous arabinogalactan was isolated and purified from L. barbarum, named LBP-3, which mainly consisted of arabinose and galactose with a molar ratio of 1.00 : 0.82. LBP-3 treatment remarkably alleviated body weight loss, histopathological damage and the overproduction of pro-inflammatory cytokines and enzymes in UC mice. Additionally, the intestinal barrier integrity was partially recovered by the up-regulated expression of MUC2 and tight junction proteins. Moreover, the gut microbiota shift was reversed by LBP-3 administration by enriching potential probiotic bacteria (e.g., Ruminococcaceae) and inhibiting the proliferation of harmful bacteria (e.g., Enterobacteriaceae). Furthermore, SCFAs, as major metabolites of LBP-3 fermentation by gut microbiota, were also promoted so as to maintain relatively favorable intestinal homeostasis. Overall, our findings suggested LBP-3 from L. barbarum could be a potential therapeutic candidate against UC via improving intestinal barrier function and partially restoring gut microbiota and its metabolites.

Abstract
The disturbance of homeostasis in bone marrow-derived mesenchymal stem cell (BMSC) adipogenesis and osteogenesis could result in pathologic consequences that plays a critical role in osteoporosis pathogenesis. In the present study, we demonstrated that miR-210-3p was abnormally upregulated within the femur of osteoporosis patients and abnormally downregulated in osteogenically differentiated BMSCs. The predicted targets of candidate miRNAs were enriched in the Pluripotent stem cell differentiation signaling. KRAS, as a vital factor of the KRAS/MAPK/ERK signaling, was upregulated in osteogenically differentiated BMSCs. In osteoporosis-BMSCs, the expression level of KRAS showed to be decreased, whereas the expression level of miR-210-3p showed to be increased. Within normal-BMSCs, miR-210-3p overexpression or KRAS silencing significantly inhibited the osteogenic differentiation and the activation of the MAPK signaling. miR-210-3p directly targeted KRAS and inhibited KRAS expression. The effects of miR-210-3p overexpression upon KRAS expression, MAPK signaling, and BMSC osteogenic differentiation were significantly reversed by KRAS overexpression. Altogether, miR-210-3p suppresses normal BMSC osteogenic differentiation through targeting KRAS and suppressing the MAPK signaling; KRAS overexpression could reverse the suppressive effects of miR-210-3p overexpression.

Abstract
Objective: Continuous glucose monitoring (CGM) were performed in children with hepatic glycogen storage disease (GSD) to accurately understand the situation of glucose levels during their treatment, and to provide support for optimizing their nutritional management. Methods: In this retrospective research, 42 patients with hepatic GSD who under went 72 h CGM were collected from Department of Pediatrics, Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology from October 2019 to January 2020. According to the genetic test results, they were divided into 5 groups: type Ⅰa, type Ⅰb, type Ⅲa, type Ⅵ and type Ⅸa. After long-term follow up and regular treatment, the clinical data (induding course, age, height, weight and biochemical parameters, etc.) on the day of CGM were summarized, and 72 h CGM were performed to assess the occurrence of hypoglycemia and hyperglycemia.χ² test, Fisher exact probability method, t test, analysis of variance or nonparametric test were used for comparison between groups. Results: Forty-two cases of hepatic GSD patients included 25 males and 17 females (20 cases of type Ⅰa, 3 cases of type Ⅰb, 10 cases of type Ⅲa, 3 cases of type Ⅵ and 6 cases of type Ⅸa).The age was 9.5 (6.7, 12.9) years, and the course of disease was 6.8 (5.1, 11.3) years. The average levels of glucose of the patients were all normal. However, the levels of standard deviation of blood glucose (SDBG) and mean amplitude of glycemic excursion (MAGE) were significantly different (F=2.747, 3.029,both P<0.05). Among them, the SDBG of type Ⅰa and Ⅲa were significantly higher than those of type Ⅸa ((1.10±0.36), (0.98±0.30) vs. (0.62±0.26) mmol/L, t=3.010, 2.440, both P<0.05), while the MAGE of type Ⅰ was higher than that of Ⅸa and Ⅲa ((2.3±0.9) mmol/L vs. (1.2±0.6) and (1.7±0.6) mmol/L, t=2.734, 2.302, both P<0.05, respectively). Conclusions: CGMS can accurately assess the fluctuations of blood glucose and effectively detect hidden hypoglycemia and hyperglycemia in hepatic GSD patients. For different types of hepatic GSD, individualized corn starch treatment doses should be given according to the different situation of blood glucose, so as to optimize the patient's treatment and improve their prognosis.

Abstract
We propose an agent-based model for predicting individual flight delays in an entire air traffic network. In contrast to previous work, more detailed parameter estimation methods were incorporated into the agent-based model, acting on the state transitions of agents. Specifically, a conditional probability model was proposed for modifying the expected departure time, which was used to indicate whether a flight had experienced the necessary waiting due to Ground Delay Programs (GDPs) or carrier-related reasons. Additionally, two random forest regression models were presented for estimating the turnaround time and the elapsed time of flight agents in the agent-based delay prediction model. The parameter models were trained and fitted using the flight data for 2017 in the United States. The performance of the delay prediction model was tested for thirty days with three types of delay levels (low, medium, and high), which were randomly selected from 2018. The experimental results showed that the average absolute error in the test days was 6.8 min, and the classification accuracy with a 15 min threshold for a two-hour forecast horizon was 89.5%. The performance of our model outperformed that of existing research. Additionally, the positive effect of introducing parameter models and the negative impact of increasing the prediction horizon on the prediction performance were further studied.

Abstract
The switch between osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) plays a key role in aging-induced osteoporosis. In this study, miR-19a-3p was obviously downregulated in BMSCs from aged humans and mice. Overexpressed miR-19a-3p evidently reduced aging-induced bone loss in mice and promoted osteogenic differentiation of BMSCs, while silenced miR-19a-3p manifestly increased aging-induced bone loss in mice and repressed osteogenic differentiation of BMSCs. Hoxa5 was significantly downregulated in the BMSCs from aged mice and contribute to miR-19a-3p-induced osteoblast differentiation as a direct target gene of miR-19a-3p. Furthermore, lncRNA Xist was found as a sponge of miR-19a-3p to repress BMSCs osteogenic differentiation. In conclusion, our study reveals the critical role of the lncRNA Xist/miR-19a-3p/Hoxa5 pathway in aging-induced osteogenic differentiation of BMSCs, indicating the potential therapeutic target for osteoporosis.

Abstract
AIM The co-expression network of long non-coding RNA ROR (lncRNA-ROR) and microRNA-185-3p (miR-185-3p) has not been focused on osteosarcoma. Therein, this work was initiated to uncover lncRNA-ROR and miR-185-3p functions in osteosarcoma. METHODS LncRNA-ROR, miR-185-3p and Yes-associated protein 1 (YAP1) expression in osteosarcoma tissues and cells were detected. The screened cells (MG63 and U2OS) were transfected with decreased and/or increased lncRNA-ROR and miR-185-3p to explore osteosarcoma progression. Tumor growth was detected by tumor xenografts in mice. RESULTS Up-regulated lncRNA-ROR and YAP1 and down-regulated miR-185-3p were found in osteosarcoma. LncRNA ROR knockdown or miR-185-3p overexpression inhibited osteosarcoma cell progression while lncRNA ROR elevation or miR-185-3p inhibition presented the opposite effects. Function of lncRNA ROR was rescued by miR-185-3p and regulated the growth and metastasis of osteosarcoma cells via modulating YAP1, the target gene of miR-185-3p. CONCLUSION This work illustrates that lncRNA-ROR down-regulation or miR-185-3p up-regulation inhibits osteosarcoma progression via YAP1 repression.

Abstract
Two-dimensional (2D) porous graphene is attractive as a high-permeability membrane for ionic and molecular separation. Here, we propose a sulfur, nitrogen dual-doped 2D porous graphene (SNPG) nanohybrid by adopting a facile one-step process. The resulting sandwich-like porous nanohybrid features uniform ion-gated nanopores for efficient transport of target heavy metal ions while blocking undesired ions, as well as abundant multi-binding ligands for selectively chelating permeated heavy metal ions. We show from systematic experiments that this SNPG nanohybrid exhibits outstanding selectivity and ability to separate Hg(ii) ions in mixtures with eight other metal ions. An excellent uptake capability (803 mg g-1) and high removal ability (>99%) within the entire pH range of 2-10 can be obtained. Given the specific 2D porous nanostructure and specific binding ligands, SNPG exhibits an ultrahigh separation factor towards Hg(ii) that is up to four orders of magnitude higher than those of Pb(ii), Cd(ii) and Cu(ii) ions, significantly higher than those of most reported adsorbents. These findings provide a new opportunity to develop selective materials and devices for applications such as efficient recognition, extraction and separation of target metal ions in complex aqueous environments.

Abstract
N6-methyladenosine (m6A) regulators are involved in the progression of various cancers via regulating m6A modification. However, the potential role and mechanism of the m6A modification in osteosarcoma remains obscure. In this study, WTAP was found to be highly expressed in osteosarcoma tissue and it was an independent prognostic factor for overall survival in osteosarcoma. Functionally, WTAP, as an oncogene, was involved in the proliferation and metastasis of osteosarcoma in vitro and vivo. Mechanistically, M6A dot blot, RNA-seq and MeRIP-seq, MeRIP-qRT-PCR and luciferase reporter assays showed that HMBOX1 was identified as the target gene of WTAP, which regulated HMBOX1 stability depending on m6A modification at the 3′UTR of HMBOX1 mRNA. In addition, HMBOX1 expression was downregulated in osteosarcoma and was an independent prognostic factor for overall survival in osteosarcoma patients. Silenced HMBOX1 evidently attenuated shWTAP-mediated suppression on osteosarcoma growth and metastasis in vivo and vitro. Finally, WTAP/HMBOX1 regulated osteosarcoma growth and metastasis via PI3K/AKT pathway. In conclusion, this study demonstrated the critical role of the WTAP-mediated m6A modification in the progression of osteosarcoma, which could provide novel insights into osteosarcoma treatment.

Abstract
Introduction Cancer-associated fibroblasts (CAFs) promote tumor progression; thus, drugs that can modify CAFs need to be identified. Methods To test the effect of cinnamaldehyde on prostate CAFs, the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-2H-tetrazolium bromide assay was used to determine their survival. When spleen cells were treated with CAF supernatant, the proliferation of T cells was inhibited as determined by flow cytometry. After cinnamaldehyde treatment, this immunosuppressive function of CAFs was partially reversed. To explore the molecular mechanism, Western blotting and the quantitative real-time polymerase chain reaction were applied, and TLR4-dependent signaling pathway-related protein and mRNA levels were quantified. Results Cinnamaldehyde acted on the TLR4-dependent signaling pathway, altering the function of CAFs such that its supernatant no longer inhibited the proliferation of T cells. Conclusion These data indicate that cinnamaldehyde can modify the functions of CAFs, which may be helpful for treating tumors. Cinnamaldehyde can suppress CAF T-cell inhibition.

Abstract
In this preliminary study, the acidic hydrolysate fingerprints of polysaccharides based on hydrophilic-interaction chromatography-evaporative light scattering detection-electrospray time-of-flight mass spectrometry (HILIC-ELSD/ESI-TOF/MS) combined with multivariate statistical analysis was developed and applied to investigate the quality of Ganoderma lucidum from different regions. Projection-to-latent-structure discrimination analysis (PLS-DA) could distinguish samples of Zhejiang regions from those of other regions. Orthogonal-projection-to-latent-structure discrimination analysis (OPLS-DA) provided clear discrimination between G. lucidum samples cultivated in Zhejiang and that from other regions, in which Polysaccharides and D-galactose could be considered as candidate biomarkers. In addition, the intraspecific differentiation of G. lucidum was preliminarily investigated with samples from Shaanxi region. They were classified into four groups by PCA and PLS-DA, in which L-rhamnose, D-xylose, L-arabinose, and mannose were considered as potential chemical markers. These preliminary results contributed to our understanding of the variance of polysaccharides in Ganoderma spp. from different geographic origins and the intraspecific differentiation from the same region, which suggest great potential in the quality control of Ganoderma spp.

Abstract
Influenza viruses are responsible for severe respiratory tract infections of individuals and may cause pandemics with a high risk of mortality and morbidity. Although vaccination is a primary means for prevention of influenza virus infections, poor vaccine performance or inadequate immune responses limits the efficacy of current vaccines and raises question regarding whether a better correlates of protection procedures should be performed. Here, we want to evaluate whether mixed polysaccharides (MPs) derived from shiitake mushroom, poriacocos, ginger, and dried tangerine peel could promote the immune response of inactivated influenza vaccine. Firstly, MPs were given to mice each day and for a total of 30 days, during which two immunizations were performed on mice on days 14 and 21. The results showed that serum total IgG and IgG2a levels were increased in MPs-treated mice on day 30. Following A/WSN/33 (H1N1) virus challenge, we found that MPs pretreatment in mice could increase mice weight gain and attenuate their clinical symptoms. Additional protective factors were also observed including prevention of excessive lung inflammation, promotion of CD19+ and CD278+ cell proportions in lung, elimination of virus in lung, and elevation of IFN-γ levels in serum. The current study demonstrate that MPs from shiitake mushroom, poriacocos, ginger, and dried tangerine peel could promote the immune efficacy and alleviate lung inflammation in mice with vaccines against H1N1 virus infection by activating both humoral and cellular immunity.

Abstract
We report a portable and highly sensitive Hg2+ nanosensor, where the CuS nanozyme functions as an Hg2+ recognition unit, a Hg2+ enrichment/preconcentration carrier, and a signal amplifier/output unit. The as-designed enrichment-detection integration strategy is customizable and endows the sensor with both a wide detection range from 50 ppt to 400 ppb and a high sensitivity with a minimum detectable Hg2+ concentration of 50 ppt. In order to make the Hg2+ nanosensor portable and cost-effective, a commercial RGB sensor is employed here in conjunction with the Hg2+-dependent colorimetric reaction. More importantly, the as-developed Hg2+ nanosensor is feasible for analysis of real samples with satisfactory accuracy (deviation <10%) and reproducibility (recovery ∼82%). Thus, this portable Hg2+ nanosensor appears to be a viable solution to meet the actual needs of on-site and real-time mercury contamination analysis and may also pave the way to colorimetric nanosensors for other metal ions.

Abstract
A preliminary relationship was illustrated between the structural characteristics and corresponding immunomodulatory activities of G. lucidum polysaccharides. Two polysaccharides (GLP-1 and GLP-2) were purified from Ganoderma lucidum extracts by gradient ethanol precipitation and a Q-Sepharose Fast Flow (QFF) strong anion-exchange column. The monosaccharide composition, high-performance gel permeation chromatography-multi-angle laser light scattering-refractive index (HPGPC-MALLS-RI), Fourier-transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), methylation analysis, and nuclear magnetic resonance (NMR) were used to characterize these polysaccharides. The GLP-1 polysaccharide was elucidated as d-galactoglucan with a flexible random linear conformation that mainly composed of →6)-β-d-Glcp-(1→, →6)-α-d-Galp-(1→, and →3)-β-d-Glcp-(1→ residues. GLP-2 was found to be a relatively homogeneous β-d-glucan that possessing →6)-β-d-Glcp-(1→ and →3)-β-d-Glcp-(1→ residues packaged into a spherical conformation. Immunomodulatory activities in vivo demonstrated that GLP-1 produced better protection of the spleen and thymus and was more effective for promoting hematopoiesis and improving IgA levels in serum. Our results suggest that the immunomodulatory activities of G. lucidum polysaccharides are highly corresponded to their structural characteristics such as carbohydrate composition, molecular weight and advanced conformation. This study provides a preliminary basis for studying the relationship between polysaccharide structure characterization and pharmacological activities.

Abstract
Malignant tumors are among the most life-threatening diseases in the world. Although many different types of antitumor agents are available, severe side effects and toxicity limit their applications. Myeloid-derived suppressor cells (MDSCs) inhibit the antitumor immune response by suppressing the proliferation of T cells, the production of cytokines and the killing of tumor cells. As MDSCs have become novel targets in cancer therapy, this research focused on the anti-MDSC function of cinnamaldehyde (CA), which is extracted from cinnamon, a traditional Chinese spice. In the present study, MDSCs isolated from the spleens of mice with colon cancer were used as an in vitro model to assess the efficacy of CA. Treatment of MDSCs with CA significantly decreased cell proliferation and induced apoptotic cell death. Subsequent experiments demonstrated that CA treatment enhanced the expression of Bax and caspase-9 and inhibited the expression of Bcl-2, suggesting that CA induced apoptosis in the MDSCs via the intrinsic pathway. Taken together, the results demonstrated that CA exhibited significant anti-MDSC activity and attenuated the suppression of the antitumor immune response, indicating a potential use for CA in cancer therapy.

Abstract
Fast, selective, and effective enrichment is critical for onsite detection and online monitoring of extremely low-concentration toxic heavy metal ions in complex environmental samples. In the current work, varied CuS nanostructures (hollow nanospheres, nanoflowers, nanoparticles) were prepared and applied to the enrichment of Hg(II) ions. Surprisingly, the as-prepared CuS nanostructures exhibited unprecedented ultrahigh selectivity and rapid uptake toward Hg(II) ions in the presence of other seven metal ions, suggesting specificity of mercury enrichment by the CuS nanostructures. Upon treating a 100 mL aqueous sample containing 8 different metal ions with only 10 mg of CuS hollow nanospheres, over 99.5% of Hg(II) ions could be removed within just 1 min, achieving a final Hg(II) ion level down to 0.1 ppb. This excellent selectivity was well accounted for by the Hard Soft Acid Base theory and especially the solubility product constant, where the solubility product constant of CuS is higher than that of HgS but lower than that of sulfides of other interfering metal ions. The current results are striking and would open a new avenue to the search for highly selective and efficient absorptive nanomaterials toward varied heavy metal ions.

Abstract
The purpose of this study is to develop a robust approach to obtain β glucans from Lentinus edodes and to characterize their structural and biological properties for sustainable utilization. The alkali extraction was optimized with an orthogonal experimental design, and a concise process for obtaining specific targeting polysaccharides from Lentinus edodes was developed in this study. After purification with a Q-Sepharose Fast Flow strong anion-exchange column, the monosaccharide composition, a methylation analysis, and NMR spectroscopy were employed for their structural characterizations. LeP-N2 was found to be composed of (1→6)-β-d-glucans with minor β-(1→3) glucosidic side chains. Atomic force microscopy (AFM) and high-performance gel permeation chromatography–refractive index–multi-angle laser light scattering (HPGPC-RI-MALLS) also revealed LeP-N2 exhibiting a compact unit in aqueous solution. This (1→6)-β-d-glucan was tested for antioxidant activities with IC50 at 157 μg/mL. Moreover, RAW 264.7 macrophage activation indicated that the release of nitric oxide (NO) and reactive oxygen species (ROS) were markedly increased with no cytotoxicity at a dose of 100 μg/mL. These findings suggest that the (1→6)-β-d-glucans obtained from Lentinus edodes could serve as potential agents in the fields of functional foods or medicine.

A water soluble polysaccharide CP-III was extracted and purified from Cyclocarya paliurus. CP-III is identified as a novel pectin-like polysaccharide with molecular weight (Mw) of 72.7 kDa. The structural features of CP-III were characterized by methylation and nuclear magnetic resonance (NMR) spectroscopy. Its depolymerized fragments were analyzed by hydrophilic interaction chromatography-Fourier transform mass spectrometry (HILIC-FTMS). The main chain of CP-III is composed of →4)GalAp(α1 → and →2)Rhap(α1 → 4)GalAp(α1→, repeatedly. The residue of →4)Galp(β1 → and →5)Araf(α1 → alternately exists on the O-4 of partial →2)Rhap(α1 → residues as side chains. On the O-3 of sectional →5)Araf(α1 → residues is a secondary branch assembled by →3)Araf(α1→. Moreover, on the non-reducing terminus of →4)Galp(β1 → occasionally have an →5)Araf(α1 → chain. Surprisingly, a sub-branch constructed by →6)Hexp(β1 → with a galacturonate or methyl galacturonate exists on the O-3 of certain →4)Galp(β1 → residues in the non-reducing terminus. In addition, a terminal Xyl is located on the O-3 of fractional →4)GalAp(β1 → residue. The highly branched polysaccharide CP-III with high water solubility can be used as food supplement and medicinal carrier in the future.

Abstract
Schisandra sphenanthera and Schisandra chinensis are widely consumed either as food or for medicinal purposes. Nevertheless, no detailed comparative assessments of their physicochemical properties and biological activity have been reported. In this paper, using hot-water extraction, alcohol precipitation, and deproteinization, we obtained polysaccharidic extracts from Schisandra sphenanthera and Schisandra chinensis (denoted as SSP and SCP, respectively) and investigated their antioxidant and immunological activities. The extracts were different from each other with regard to sugar, protein, and uronic acid contents. Both extracts were mainly composed of arabinose, glucose, and galactose, but their contents varied greatly; SSP had more galacturonic acid. Compared with SCP, SSP had stronger free radical scavenging ability, protective effects on biomolecules, cellular antioxidant activity, owing to its higher protein (35.35 ± 1.73%) and uronic acid (12.81 ± 1.15%) contents. With respect to cell viability, neutral red phagocytosis, NO production, and acid phosphatase activity, SCP had stronger effects than SSP; this was largely due to its high levels of mannose, galactose, arabinose, and glucose. These results provide evidence to support the use Schisandra-derived polysaccharides for several purposes, including clinical, agricultural, and industrial applications.

Abstract
Immunity due to immune balance contributes to disease prevention and treatment. Radix Codonopsis polysaccharide (RCP) is isolated from the root of the Chinese herb Codonopsis pilosula. Previous studies have indicated that RCP has immunomodulatory activities; however, the effects of RCP on immunity, especially immune balance, are still largely unknown. In the present study, we investigated the effects of RCP on T-cell balance in mice. The mice were pretreated intragastrically with or without RCP for 15 days and injected with hydrocortisone on days 10-15 to disturb the immune system. The spleen and thymus were weighed and used to calculate immune organ indexes. The percentages of CD4+ T cells, CD8+ T cells, Th1 cells, Th2 cells, regulatory T cells (Tregs) and Th17 cells in peripheral blood were assayed by flow cytometry. Pro-inflammatory and anti-inflammatory cytokines, TNF-α, IL-1β and IL-10, in serum were determined by enzyme-linked immunosorbent assay (ELISA) kits. The results showed that RCP pretreatment could maintain the homeostasis of CD8+ T cells, Tregs, Th17 cells, TNF-α, IL-1β and IL-10 in hydrocortisone-treated mice. Furthermore, RCP pretreatment maintained the immune balance of CD4+/CD8+ T cells, Th1/Th2 cells, Tregs/Th17 cells, IL-10/TNF-α and IL-10/IL-1β. Taken together, RCP pretreatment had beneficial effects on the maintenance of T-cell balance against hydrocortisone disturbance in mice and potential to be developed into novel functional food.

Abstract
Background Severe acute pancreatitis (SAP) is an acute abdominal disease characterized by pancreatic necrosis and systemic disease. In a previous study, we showed that bone marrow-derived mesenchymal stem cells (BMSCs) can reduce SAP by secreting microRNA (miR)-9; however, the underlying mechanism remains unclear. The present study investigated the mechanism underlying BMSC-induced pancreatic regeneration. Methods BMSCs were isolated, and miR-9 modified/antagonized BMSCs (pri-miR-9-BMSCs/TuD-BMSCs) were generated and injected into SAP rats. The levels of inflammatory cytokines and histopathologic changes were examined using ELISA and H&E staining. Angiogenesis was analyzed by qRT-PCR, western blotting, and immunohistochemistry. Cell function tests, dual luciferase reporter assays, cell co-culture, western blotting, and cell tracing were used to explore the mechanisms underlying miR-9 induced angiogenesis. Results Pri-miR-9-BMSCs induced angiogenesis in SAP rats (Ang-1↑, TIE-2↑, and CD31↑) and repaired damaged vascular endothelial cells (VECs) in vitro, promoting angiogenesis (Ang-1↑, TIE-2↑, PI3K↑, AKT↑, p-AKT↑, CD31↑, and CD34↑). Pri-miR-9-BMSCs released miR-9 into VECs or injured pancreatic tissue, targeting the VE-cadherin gene and promoting PI3K/AKT signaling to treat SAP (VE-cadherin↓, β-catenin↓, PI3K↑, p-AKT↑), whereas antagonizing miR-9 in BMSCs did not alleviate or aggravated SAP. Conclusions Pri-miR-9-BMSCs can repair injured pancreatic tissue by secreting miR-9 and promoting angiogenesis.

Abstract
Diabetes is generally regarded as a metabolic disorder disease caused by various reasons, including pancreas islet injury and lipid metabolism disorders. The aqueous extract of Cyclocarya paliurus leaves (CPAE) was reported to be anti-diabetic. However, the possible molecular mechanisms have not been investigated. To elucidate the anti-diabetic effects of CPAE and the underlying potential mechanisms, we performed transcriptome profiling (RNA-Seq and miRNA-Seq) on the pancreas and liver from non-diabetic, diabetic and diabetic-CPAE rats. Our results demonstrated the CPAE could reduce excessive oxidative stress and inflammation in the pancreas, and maintain the balance of glucose and lipid metabolism in the liver. Transcriptome profiling and regulatory network analysis indicated that CPAE may ameliorate diabetes through improving β-cell survival and strengthening insulin secretion in the pancreas. Meanwhile, CPAE could improve impaired lipid metabolism and reduce excessive oxidative damage in the liver probably through miR-200/375-Aldh1b1/Hps5-Hes1 co-regulatory network. Taken together, our biochemical experiments combined with transcriptome profiling showed that the effects of CPAE on anti-diabetes may work through protecting pancreatic β-cell, improving dyslipidaemia and lipid metabolism disorders.

Abstract
Lycium barbarum polysaccharide (LBP) is isolated from the fruit of Chinese herbal Lycium barbarum. Previous studies had demonstrated that LBP could inhibit tumor growth and enhance the immunity in mice. However, the effect of LBP on systemic and local immune responses in vivo, especially on phenotypic and functional changes of T cells, is still largely unknown. In the present study, we investigated the effects of LBP on systemic and local T cell-dependent antitumor immune responses in H22 tumor-bearing mice. The results showed that LBP could inhibit the solid tumor growth in mice, but showed little effect on the body weight or spleen index. Furthermore, LBP could maintain high levels of T cells in peripheral blood (PB), tumor draining lymph node (TDLN), and tumor tissue, prevent the increase of Tregs while promote infiltration of CD8+ T cells in tumor tissue, inhibit the production of TGF-β1 and IL-10 in serum, decrease the exhaustion phenotype of T cells, and maintain cytotoxicity of lymphocytes. Taken together, our results demonstrated that LBP simultaneously induced systemic and local immune responses in H22 tumor-bearing mice by alleviating immunosuppression and maintaining antitumor immune responses in mice.

Abstract
BACKGROUND/AIMS Studies have shown that miR-194 functions as a tumour suppressor and is associated with tumour growth and metastasis. This study intends to uncover the mechanism of tumour suppression by miR-194. The expression of miR-194 in osteosarcoma cell lines and tissues were monitored by real-time PCR. METHODS The proliferation ability was examined by MTT assay. Migration and apoptosis of cells were monitored by migration assay and flow cytometry, respectively. The regulation of miR-194 on CDH2 was determined by luciferase assays and western blot assays. RESULTS The results showed that miR-194 was significantly reduced in osteosarcoma compared with that in normal bone tissue. Overexpression of miR-194 significantly attenuated the proliferation and migration and induced the apoptosis of osteosarcoma cells. Furthermore, we demonstrated that miR-194 has inhibited the malignant behaviour of osteosarcoma by downregulating CDH2 expression. CONCLUSIONS These findings suggested that miR-194 may act as a tumour suppressor in osteosarcoma. miR-194/CDH2 may be a novel therapeutic target in the treatment of osteosarcoma.

immunotoxicity and enhance antitumor activity of doxorubicin (Dox) in mice. A
water-soluble LBP fraction, designated LBP3, was isolated from edible Chinese
herbal Lycium barbarum and used in this study. To investigate
the effect of LBP3 on Dox-induced immunotoxicity, tumor-free mice were used and
treated with either normal saline, Dox, or Dox plus LBP3. To investigate the
effect of LBP3 on antitumor activity of Dox, H22 tumor-bearing mice were used
and treated with either normal saline, Dox, LBP3, or Dox plus LBP3. The results
showed that LBP3 did not protect against the body weight loss caused by Dox, but
it promoted the recovery of body weight starting at day 5 after Dox treatment in
tumor-free mice. LBP3 also improved peripheral blood lymphocyte counts, promoted
cell cycle recovery in bone marrow cells, and restored the cytotoxicity of
natural killer cells. Furthermore, in H22 tumor-bearing mice, LBP3 enhanced
antitumor activity of Dox and improved peripheral blood lymphocyte counts and
the cytotoxicity of splenocytes. In brief, our results demonstrated that LBP3
could reduce the immunotoxicity and enhance antitumor activity of Dox.

Abstract
To study the effect and underlying molecular mechanism of eugenol on CD11b+Gr1+ myeloid-derived suppressor cells (MDSCs). The effect of eugenol on the inhibition of immortalized MDSC cell line MSC-2 and murine peritoneal macrophages was detected by MTT. Flow cytometry was used to detect the pro-apoptosis effect of eugenol on MDSCs. The expression levels of apoptosis-related proteins were detected by western blot. Eugenol has a selective inhibitory effect on MDSCs in a dose-dependent manner, which activates an endogenous apoptosis pathway, leading to apoptosis. Eugenol promotes the apoptosis of MDSCs via the intrinsic pathway. To study the effect and underlying molecular mechanism of eugenol on CD11b+Gr1+ myeloid-derived suppressor cells (MDSCs).![]()

Abstract
Functional dyspepsia (FD) is one of the most prevalent functional gastrointestinal disorders (FGIDs). Accumulated evidence has shown that FD is a metabolic disease that might relate to gut microbiota, but the relationship between microbiome and the host metabolic changes is still uncertain. To clarify the host–microbiota co-metabolism disorders related to FD, an integrated approach combining 1H NMR-based metabolomics profiles, polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and 16S rRNA gene sequencing was used to investigate the relationship among FD, metabolism of gut microbiota and the host. 34 differential urinary metabolites and 19 differential fecal metabolites, which affected the metabolism of energy, amino acids, nucleotides and short chain fatty acids (SCFAs), were found to have associated with FD. Based on the receiver operating characteristic (ROC) analysis, 10 biomarkers were screened out as diagnostic markers of FD. Meanwhile, the concentrations of Flintibacter, Parasutterella, Eubacterium and Bacteroides significantly increased in the FD group, whereas Eisenbergiella, Butyrivibrio, Intestinimonas, Saccharofermentans, Acetivibrio, Lachnoanaerobaculum and Herbinix significantly decreased. Furthermore, the above altered microbiota revealed a strong correlation with the intermediate products of the tricarboxylic acid (TCA) cycle, amino acids and SCFAs. In our study, it suggested that the energy metabolism was mainly disturbed in FD rats. Our findings also demonstrated that FD might be the result of gut microbiota and metabolism disorders, which was potentially valuable to enrich our understanding of the pathogenesis of FD. Functional dyspepsia (FD) is one of the most prevalent functional gastrointestinal disorders (FGIDs). The aim of our study was to evaluate the effects of FD on the microbiota and its metabolic profiles in feces and urine.![]()

Abstract
Hepatocellular carcinoma (HCC) is the leading cause of cancer related death worldwide. The number of deaths is proportional to the global incidence, which highlights the aggressive tumor biology and lack of effective therapies. Dysregulation of microRNAs has been implicated in carcinogenesis and progression of liver cancer. Here, we identified that miR-1258 was significantly downregulated in HCC and associated with poor patients' survival. Overexpression of miR-1258 significantly inhibits liver cancer cell growth, proliferation and tumorigenicity through increasing cell cycle arrest in G0/G1 phase and promotes cell apoptosis. Interestingly, stable overexpression of miR-1258 suppresses cell migration, stemness and increases sensitivity of HCC cells to chemotherapy drug like doxorubicin. The CDC28 protein kinase regulatory subunit 1B (CKS1B) was identified as a functional downstream target of miR-1258. Re-expression of CKS1B overcomes miR-1258 induced apoptosis and increases stemness of HCC cells, suggesting that loss of miR-1258 contributes to carcinogenesis and progression of liver cancer through targeting CKS1B. Therefore, loss of miR-1258 may be a potential diagnostic and prognostic biomarker and blocking miR-1258-CKS1B axis is a potential therapeutic strategy in HCC.

Abstract
Post-operative epidural fibrosis is a biological response after laminectomy that may lead to clinical symptoms, such as radicular pain. An ideal material for prevention of epidural fibrosis should be able to inhibit fibroblast adhesions and reduce formation of scar tissue. An injectable hydrogel would be the material of choice for this purpose, since it could fill an irregular surgical defect completely, gelate in situ and be delivered in a minimally-invasive manner. The objective of this study was to evaluate, in vitro and in vivo, the cytocompatibility and anti-adhesive effect of an oxidised hyaluronic acid/adipic acid dihydrazide (oxi-HA/ADH) hydrogel. Different cell types present in the spine were used to test the cytocompatibility of the hydrogel. The hydrogel extraction medium had no deleterious effects on neural cells (PC-12), but reduced fibroblasts viability (NIH/3T3). Although the hydrogel did not change the release of lactate dehydrogenase from myoblasts (C2C12) and Schwann cells (RSC96), the extraction medium concentration slightly affected the mitochondrial activity of these two cell types. qPCR showed that the hydrogel down-regulated S100a and P4hb expression in NIH/3T3 cells, supporting the hypothesis that the hydrogel might inhibit fibroblast activity. The animal study showed a reduction of scar tissue formation as well as severity of adhesion between scar tissue and the dura mater in a rat laminectomy model. Superficially, the peel-off test showed significantly decreased tenacity. In conclusion, the oxi-HA/ADH hydrogel is a promising injectable and thermosensitive material for prevention of post-operative epidural fibrosis.

Abstract
Nowadays, the role of miRNA in tumorigenesis has been largely reported. It was found that miR-506 might be associated with tumorigenesis of various cancers. The present study was aimed to investigate the character of miR-506 and some related factors in human osteosarcoma (OS) carcinogenesis. The expression level of miR-506 was downregulated in OS compared with the normal control group by RT-PCR, both in vivo and in vitro. In addition, IL-1β stimulation decreased the expression of miR-506. MiR-506 interfered with JAG1 gene transcription throughmiR-506 binding to the 3'-UTR region of JAG1 gene. Further siRNA strategy suggested that IL-1β may regulate miR-506 level via NF-κB, and then alter the JAG1 expression. Besides, the suppression of JAG1 by miR-506 inhibited OS cell proliferation. Taken together, our data indicate a process of NF-κB-induced miR-506 suppression and JAG1 upregulation upon IL-1β induction, which can be regarded as a new pathway for modulating cell proliferation via miR-506. It may be of clinical value in treating OS in the future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dictyophora indusiata is a medicinal mushroom traditionally used in China for a variety of conditions, including inflammatory and neural diseases. D. indusiata polysaccharides (DiPS) are shown to have in vitro antioxidant activity but in vivo evidence is lacking. This study aimes to explore the antioxidant capacity and related neuroptotective activities of DiPS using wild-type and neurodegenerative Caenorhabditis elegans models. MATERIALS AND METHODS The antioxidant capacities of DiPS were first determined using paraquat survival and Pgst-4::GFP expression assays in wild-type and transgenic C. elegans models, respectively, and then further investigated by determining reactive oxygen species (ROS) level, malondialdehyde (MDA) content and superoxide dismutase (SOD) activity as well as functional parameters of mitochondria. The activation of stress response transcription factors and neuroptotective activities were examined using nuclear localization and chemosensory behavioral assays in transgenic nematodes, respectively. RESULTS DiPS was shown not only to increase survival rate and reduce stress level under paraquat-induced oxidative conditions but also to decrease ROS and MDA levels and increase SOD activity in C. elegans models. Moreover, DiPS was also able to restore the functional parameters of mitochondria, including membrane potential and ATP content, in paraquat-stressed nematodes. In addition, nuclear translocation assays demonstrate that the stress response transcription factor DAF-16/FOXO was involved in the antioxidant activity of the polysaccharide. Further experiments reveal that DiPS was capable of reducing ROS levels and alleviating chemosensory behavior dysfunction in transgenic nematode models of neurodegenerative diseases mediated by polyglutamine and amyloid-β protein. CONCLUSIONS These findings demonstrate the antioxidant and neuroprotective activities of the D. indusiata polysaccharide DiPS in wild-type and neurodegenerative C. elegans models, and thus provide an important pharmacological basis for the therapeutic potential of D. indusiata in neurodegeneration.

Abstract
Polysaccharide compounds (PCs), which composed of different kinds of polysaccharides always isolated from different kinds of traditional Chinese medicine, are now attracting more and more attentions due to their strong immunomodulatory activities beyond the corresponding one-component polysaccharides. In this study, we demonstrated for the first time that PCs-1 and PCs-2 had strong immunomodulatory effects on macrophages both in in vitro and in vivo models by atomic force microscopy (AFM). By high resolution AFM imaging, PCs-1 and PCs-2 were found to inhibit LPS induced cell surface particle size and roughness increase in RAW264.7 macrophages, demonstrating the anti-inflammatory effects of PCs-1 and PCs-2 on macrophages. PCs-1 and PCs-2 were also proved to increase the particle size and roughness of resting RAW264.7 macrophages, which suggested that PCs could activate resting RAW264.7 macrophages. And additionally, PCs-1 and PCs-2 were also found to reverse the surface particle size and roughness decrease of peritoneal macrophages isolated from cyclophosphamide induced immunosuppressive mice, suggesting the activation effects of PCs-1 and PCs-2 on immunosuppressive macrophages. These results further enhanced our understanding of macrophage activations by direct imaging of cell surface ultrastructure and also highlighted AFM as a novel nanotool for macrophage detections. And most importantly, these results also indicated the outstanding immunomodulatory effects of PCs on macrophages, which therefore suggested that PCs could be served as a kind of novel immunomodulatory agents that would benefit human health.

Abstract
As an important hallmark in cancer progress, inflammation attracts more and more interests in recent years. Lots of evidences support the positive effect of n-3 PUFA in inflammation-associated diseases, the supplement of these fatty acids is thought to be promising in the prevention and treatment of cancers. In this review, we summarize some current knowledge of the mechanisms by which n-3 PUFA are thought to attenuate cancer associated inflammation, and we also introduce the current situation of n-3 PUFA in clinic.
