Abstract
Six new citreoviridins (citreoviridins J-O, 1-6) and twenty-two known compounds (7-28) were isolated from the deep-sea-derived Penicillium citreonigrum MCCC 3A00169. The structures of the new compounds were determined by spectroscopic methods, including the HRESIMS, NMR, ECD calculations, and dimolybdenum tetraacetate-induced CD (ICD) experiments. Citreoviridins J-O (1-6) are diastereomers of 6,7-epoxycitreoviridin with different chiral centers at C-2-C-7. Pyrenocine A (7), terrein (14), and citreoviridin (20) significantly induced apoptosis for HeLa cells with IC50 values of 5.4 μM, 11.3 μM, and 0.7 μM, respectively. To be specific, pyrenocine A could induce S phase arrest, while terrein and citreoviridin could obviously induce G0-G1 phase arrest. Citreoviridin could inhibit mTOR activity in HeLa cells.

Abstract
From the deep-sea-derived Fusarium sp. ZEN-48, four known compounds were obtained. Their structures were established by extensive analyses of the NMR, HRESIMS, and the X-ray crystal-lographic data as brefeldin A (BFA, 1), brevianamide F (2), N-acetyltryptamine (3), and (+)-diaporthin (4). Although BFA was extensively investigated for its potent bioactivities, its role on TNFα-induced necroptosis was incompletely understood. In this study, BFA showed significant inhibition on TNFα-induced necroptosis by disrupting the necrosome formation and suppressing the phosphorylation of RIPK3 and MLKL (IC50 = 0.5 μM). While, it had no effect on TNFα-induced NF-κB/MAPKs activation and apoptosis. The finding raised significant implications of BFA for necroptosis-related inflammatory disease therapy and new drug development from marine fungi.

Abstract
Butyrolactone I (BTL-I) is a butanolide isolated from the deep-sea-derived fungus, Aspergillus sp. It provides a potential new target for the prevention and treatment of food allergies. This study aimed to investigate the metabolic and pharmacokinetic profile of BTL-I in rats. The metabolic profiles were obtained by UHPLC–Q-TOF-MS. As a result, eleven metabolites were structurally identified, and the proposed metabolic pathways of BTL-I were characterized. The main metabolites were the oxidative and glucuronidative metabolites. In addition, a sensitive UHPLC–MS/MS method was established for the quantitation of BTL-I in rat plasma (LOQ = 2 ng/mL). The method was fully validated and successfully applied to the pharmacokinetic study of BTL-I in rats after oral administration or intravenous administration. The oral bioavailability was calculated as 6.29%, and the maximum plasma concentrations were 9.85 ± 1.54 ng/mL and 17.97 ± 1.36 ng/mL for intravenous and intragastric dosing groups, respectively.

Abstract
Objective: To investigate the effect of miR-369-3p targeting ACTN4 expression on proliferation and apoptosis of hepatocellular carcinoma cells. Methods: Real-time quantitative polymerase chain reaction (RT-qPCR) and western blot were used to detect the expression levels of miR-369-3p and ACTN4 in hepatocarcinoma tissues and adjacent tissues. MiR-369-3p mimics, miR-negative control (NC), si-ACTN4, and si-NC were transfected into hepatocellular carcinoma MHCC97H cells by liposome method. Cell proliferation was detected by 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-dipheny-ltetrazolium bromide (MTT) assay. Flow cytometry was used to detect cell cycle and apoptotic rates. The dual luciferase reporter assay was used to verify the targeted regulation of ACTN4 by miR-369-3p. Western blot was used to detect the expressions of cyclin D1, p21, Bcl-2 and Bax. Results: The expression level of miR-369-3p in liver cancer tissue was lower than that in adjacent tissues [(0.46±0.04) vs (1.00±0.08), P<0.001)], while the expression level of ACTN4 was higher than that in adjacent tissues [mRNA (3.12±0.29) vs (1.01±0.09); protein (0.61±0.06) vs (0.25±0.03), P<0.001]. Overexpression of miR-369-3p significantly decreased the cell viability[(0.71±0.06) vs (1.26±0.11), P<0.001)], increased cell apoptosis rate [(20.16±2.11)% vs (6.25±0.64)%, P<0.001], increased the proportion of cells in G(1) phase [(31.14±3.36)% vs (51.56±5.23)%, P<0.001], decreased the proportion of cells in S phase [(32.44±3.56)% vs (14.33) ±1.45)%, P<0.001], increased the levels of p21 and Bax protein (P<0.001), and decreased the levels of cyclin D1 and Bcl-2 protein (P<0.001). Inhibition of the expression of ACTN4 significantly reduced the cell viability [(0.78±0.07) vs (1.24±0.12), P<0.001], increased the apoptosis rate [(6.58±0.66)% vs (18.32±1.82)%, P<0.001], increased the proportion of cells in G(1) phase [(48.69±4.21)% vs (30.33±3.01)%, P<0.001], decreased the proportion of cells in S phase [(36.21±3.42)% vs (18.54±1.61)%, P<0.001], increased the protein levels of p21 and Bax (P<0.001), and decreased the levels of cyclin D1 and Bcl-2 protein (P<0.001). Compared with the miR-369-3p+ pcDNA group, overexpression of ACTN4 increased the proliferation ability of hepatocellular carcinoma MHCC97H cells at 72 hours of culture[(1.12±0.11) vs (0.68±0.06), P<0.001], significantly reduced the proportion of cells in G(1) stage [(38.81±3.24)% vs (51.80±4.57)%, P<0.001], significantly increased the proportion of S-phase cells [(31.65±3.11)% vs (15.69±1.44)%, P<0.001], decreased cell apoptosis rate [(13.86±1.37)% vs (22.69±2.24)%, P<0.001], increased protein expressions of cyclin D1 and Bcl-2 (P<0.001), decreased the protein expressions of p21 and Bax (P<0.001). Conclusion: MiR-369-3p can induce cell cycle arrest in G(1) phase, inhibit the proliferation and promote apoptosis of liver cancer cells by regulating the expression of ACTN4.

Abstract
Except for a few stick insects that are economically valuable, most species be considered to be forest pests, so it is extremely important to obtain plant host-use information of more stick insects. In this paper, the plant hosts of three species of stick insects were recorded for the first time. We also discovered these stick insects can feed upon the flowers or leaves of plants. Lopaphus unidentatus (Chen & He, 1995) (Phasmida: Lonchodidae) attacked Hypericum choisianum Wall. ex N. Robson, 1973 (Hypericaceae), Leurophasma dolichocercum Bi, 1995 (Phasmida: Aschiphasmatidae) attacked Antenoron filiforme (Thunb.) Roberty & Vautier, 1964 (Polygonaceae) and Megalophasma granulatum Bi, 1995 (Phasmida: Lonchodidae) attacked Debregeasia orientalis C. J. Chen, 1991 (Urticaceae). Finally, we were lucky enough to also obtain photographs of them mating and feeding.

Abstract
Objective: To study the effect of iron deficiency level for oral iron absorption in iron deficient patients. Methods: 37 non-pregnant female patients who were diagnosed with iron deficiency and 13 healthy females who completed their physical examination at the outpatient department of the Anemia Center of the Institute of Hematology & Blood Diseases Hospital from July 2018 to June 2020 were included. Hepcidin and C2-C0 of oral iron absorption test were analyzed in different iron deficiency and serum ferritin level. Results: The median of Hepcidin in IDA, ID/IDE and healthy control group were 4.9 (2.17-32.86) , 26.98 (11.02-49.71) and 69.89 (42.23-138.96) μg/L (P<0.001) , respectively. Hepcidin level of IDA group was lower than that of ID/IDE group (adjusted P=0.005) and healthy control (adjusted P<0.001) . Hepcidin level of ID/IDE group had no significant difference compared with healthy control (adjusted P=0.22) . The mean of C2-C0 in IDA, ID/IDE and healthy control group were (35.30±21.68) , (37.90±14.06) and (23.57±10.14) μmol/L (P=0.130) , respectively. Multilinear regression analysis showed C0, SF, sTFR and HGB were independent factors for Hepcidin in iron deficient patients, with an equation of Hepcidin=-31.842-0.642*C0+2.239*SF+1.778*sTFR+0.365*HGB-0.274*RET-HB. We didn't find independent factor of C2-C0. Conclusion: The degree of iron deficiency had an effect on oral iron absorption. Patients of ID/IDE group absorbed iron more slowly than patients of IDA group. Iron deficient patients with normal gastrointestinal function absorbed more iron by oral administration when they were in a more serious iron deficient stage. Hepcidin was a better parameter to distinguish iron absorption level among different iron deficient patients than C2-C0 of oral iron absorption test.

Abstract
Two new (1-2) and three known (3-5) sorbicillinoids were isolated from the deep-sea-derived fungus Penicillium allii-sativi MCCC 3A00580. Compounds 1 and 2, named sorbicatechols C and D, were two new hybrid dihydrosorbillinoids. Their structures were established mainly by spectroscopic analyses and electronic circular dichroism (ECD) calculations. All five isolates were tested for antiproliferative activities against four tumor cell lines of MCF-7, HT-29, HuH-7, and LNCap. Compounds 2 and 5 inhibited HT-29 cells in a good dose-dependent manner. Mechanism investigation uncovered that they could significantly induce cell cycle G2-M phase arresting by increasing the protein levels of p-H3 and cyclin B1.

Abstract
Nevadensin (NEV), a natural flavonoid compound derived from Lysionotus pauciflorus Maxim, has numerous biological activities. However, few researchers have examined its potential impact on alleviating allergies. In the present study, NEV was found to upregulate rectal temperature, suppress the development of diarrhea, and decrease the levels of serum specific immunoglobulin E, histamine and mouse MC protease-1 in ovalbumin-allergic mice. Moreover, NEV also alleviated passive cutaneous anaphylaxis reactions and inhibited the release of β-hexosaminidase and histamine in bone marrow-derived mast cells. Furthermore, we provide the first demonstration that NEV decreases the expression of c-Kit and suppresses the proliferation of bone marrow-derived mast cells and accelerates their apoptosis. These findings indicated that L. pauciflorus-derived NEV might have the potential to alleviate food hypersensitivity.

Abstract
Ten new C9 polyketides (asperochratides A-J, 1-10) and 14 known miscellaneous compounds (11-24) were isolated from the deep-sea-derived fungus Aspergillus ochraceus. Structures of the new compounds were elucidated by extensive spectroscopic analyses, modified Mosher's method, Mo2(OAc)4 induced circular dichroism (ICD) experiments, and ECD calculations. Structurally, compounds 1-11 and 16-18 share the same polyketide origin of the skeleton and belong to aspyrone co-metabolites. All isolates were tested for cytotoxic, anti-food allergic, anti-H1N1 virus, anti-microbe, and anti-inflammatory activities in vitro. Results showed that compounds 5-8 and 13-17 exerted significant cytotoxic effects on BV-2 cell line, and compound 16 showed the potential of anti-inflammatory activities.

Abstract
Coumarin is an important organic heterocyclic compound with a wide range of sources in nature. It plays an important role in the drug discovery process due to its existence in diverse biologically active compounds and its broad bioactivity. In this study, the anti-allergic activity of coumarin was evaluated using an ovalbumin (OVA)-induced mouse food allergy model and an immunoglobulin (Ig)E mediated mouse bone marrow-derived mast cell (BMMC) model. Coumarin could alleviate the OVA-induced allergic symptoms, decrease the diarrhea rates, and promote the rectal temperature rise in allergic mice. Moreover, coumarin had the ability to reduce the levels of histamine and mouse mast cell proteinases, inhibit OVA-specific IgE, and significantly decrease the population of mast cells in the spleen and mesenteric lymph nodes. Coumarin could also significantly suppress mast cell-dependent passive cutaneous anaphylaxis. Additionally, the number of mature BMMCs was decreased as coumarin caused the suppression of c-KIT receptors. Furthermore, coumarin up-regulated the apoptosis of OVA-activated BMMCs in a concentration-dependent manner. In conclusion, coumarin displayed effective anti-food allergy activity via the regulation of mast cell function and numbers. Coumarin and its derivatives provide a new direction for the development of anti-food allergic drug components.

Abstract
Two new (1, 2) and one known (3) meroterpenoids were isolated from the deep-sea-derived fungus Penicillium allii-sativi. The relative structures of new compounds were determined on the basis of an extensive analysis of the NMR and MS data, and the absolute configurations were established by ECD calculations. Andrastone A (1) is a rare andrastin bearing an unusual cyclopentan-1,3-dione. It shows a selectively antiproliferative effect against HepG2 tumor cells with an IC50 value of 7.8 μM. Mechanism study showed that apoptosis via Caspase and RXRα pathways are responsible for the inhibitory effect.

Abstract
This study was designed to determine whether plasma CXCL12 levels in postmenopausal osteoporosis (PMOP) patients are related to disease severity. A total of 91 PMOP females were recruited, and 88 postmenopausal non-osteoporotic (PMNOP) women and 90 healthy females were incorporated as controls. Dual-energy X-ray absorptiometry was utilised to explore bone-mineral density (BMD). The Genant semi-quantitative grading scale was used for vertebral fractures, and plasma CXCL12/SDF-1 levels were investigated by ELISA. Plasma TNF-α and C-telopeptide cross-linked collagen type 1 (CTX-1) were also tested. The Oswestry Disability Index (ODI) and a visual analogue scale (VAS) were completed in order to assess clinical severity. Plasma CXCL12 levels were considerably elevated in PMOP females compared to PMNOP women and healthy controls. Plasma CXCL12 concentrations were positively correlated with the Genant grading system. We observed significant and negative correlations of plasma CXCL12 levels with lumbar spine, femoral neck and total hip BMD. Moreover, plasma CXCL12 concentrations were positively correlated to VAS and ODI, as well as plasma TNF-α and CTX-1 levels. In conclusion, elevated plasma CXCL12 levels are correlated with disease severity in PMOP females.
