Abstract
UNLABELLED Bone mineral density (BMD) is an independent risk factor of osteoporosis-related fractures. We performed gene-based burden tests to assess the association between rare variants and BMD, and identified several BMD candidate genes. PURPOSE BMD is highly heritable and a major predictor of osteoporotic fractures, but its genetic basis remains unclear. We aimed to identify rare risk variants contributing to BMD. METHODS Utilizing the newly released UK Biobank 200,643 exome dataset, we conducted a gene-based exome-wide association study in males and females, respectively. First, 100,639 males and 117,338 females with BMD values were included in the polygenic risk scores (PRS) analysis. Among individuals with lower 30% PRS, cases were individuals with top 10% BMD, and individuals with bottom 10% BMD were the controls. Considering the effects of vitamin D (VD), individuals with the highest 30% VD concentration were selected for VD-BMD analysis. After quality control, 741 males and 697 females were included in the BMD analysis, and 717 males and 708 females were included in the VD-BMD analysis. The variants were annotated by ANNOVAR software, then BMD and VD-BMD qualified variants were imported into the SKAT R-package to perform gene-based burden tests, respectively. RESULTS The gene-based burden test of the exonic variants identified genome-wide candidate associations in ANKRD18A (P = 1.60 × 10-5, PBonferroni adjust = 2.11 × 10-3), C22orf31 (P = 3.49 × 10-4, PBonferroni adjust = 3.17 × 10-2), and SPATC1L (P = 1.09 × 10-5, PBonferroni adjust = 8.80 × 10-3). For VD-BMD analysis, three genes were associated with BMD, such as NIPAL1 (P = 1.06 × 10-3, PBonferroni adjust = 3.91 × 10-2). CONCLUSIONS Our study suggested that rare variants contribute to BMD, providing new sights for broadening the genetic structure of BMD.

Abstract
Dexmedetomidine might reduce delirium after cardiac surgery. We allocated 326 participants to an infusion of dexmedetomidine at a rate of 0.6 μg kg-1 for 10 min and then at 0.4 μg.kg-1 .h-1 until the end of surgery; 326 control participants received comparable volumes of saline. We detected delirium in 98/652 (15%) participants during the first seven postoperative days: 47/326 after dexmedetomidine vs. 51/326 after placebo, p = 0.62, adjusted relative risk (95%CI) 0.86 (0.56-1.33), p = 0.51. Postoperative renal impairment (Kidney Disease Improving Global Outcomes stages 1, 2 and 3) was detected in 46, 9 and 2 participants after dexmedetomidine and 25, 7 and 4 control participants, p = 0.040. Intra-operative dexmedetomidine infusion did not reduce the incidence of delirium after cardiac valve surgery but might impair renal function.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As one of the important traditional Chinese medicines, Alpinia oxyphylla could warm and tonify the kidney and spleen. It has been used as anti-salivation, anti-diarrhea in various diseases. In recent years, many studies have reported the significant effect of Alpinia oxyphylla on improving cognitive ability, anti oxidative stress and protecting neurons. AIMS OF THE STUDY In this paper, we studied whether AE and its main active components could improve M1 and M2 polarization, inhibit neuroinflammation through triggering receptor expressed on myeloid cells 2 (TREM2), and exert anti-inflammatory effects. MATERIALS AND METHODS In this paper, the concentrations of inflammatory cytokines such as NO, TNF-α, IL-10 were assessed using detection kits respectively. Arg-1 and Iba-1, as polarized markers of M1 and M2, were detected by Immunofluorescence staining. CD86 and CD206 were tested by flow cytometry as surface markers of M1 and M2. Furthermore, RT-PCR was performed to determinate TNF-α, IL-10, Arg-1, and Iba-1. Western blot was used to test the activation of PI3K/AKT/GSK3β and BDNF/TrkB/TLR4 signaling pathways. TREM2 siRNA treatment further verified the action target of Chrysin, the main active ingredient of Alpinia oxyphylla. Molecular docking study was performed to investigate the binding mode between Chrysin and the human TREM2. RESULTS We found that AE could promote the phenotypic transformation of microglia from M1 to M2, and similar effects of Chrysin were observed. Furthermore, downregulation of TREM2 blocked the anti-neuroinflammation of Chrysin, and inhibited the shift of M1 phenotype to M2 phenotype. Additionally, TREM2-siRNA suppressed the effects of Chrysin on PI3K/AKT/GSK3β and BDNF/TrkB/TLR4 signaling pathways. CONCLUSIONS Our findings indicated that AE could improve the polarization response of microglia. TREM2 plays a vital role in the microglial repolarization effects of Chrysin through PI3K/AKT/GSK3β and BDNF/TrkB/TLR4 signaling pathways regulated by neuroinflammation.

Abstract
Primary familial brain calcification (PFBC) is a rare neurodegenerative and neuropsychiatric disorder characterized by bilateral symmetric intracranial calcification along the microvessels or inside neuronal cells in the basal ganglia, thalamus, and cerebellum. Slc20a2 homozygous (HO) knockout mice are the most commonly used model to simulate the brain calcification phenotype observed in human patients. However, the cellular and molecular mechanisms related to brain calcification, particularly at the early stage much prior to the emergence of brain calcification, remain largely unknown. In this study, we quantified the central nervous system (CNS)-infiltrating T-cells of different age groups of Slc20a2-HO and matched wild type mice and found CD45+CD3+ T-cells to be significantly increased in the brain parenchyma, even in the pre-calcification stage of 1-month-old -HO mice. The accumulation of the CD3+ T-cells appeared to be associated with the severity of brain calcification. Further immunophenotyping revealed that the two main subtypes that had increased in the brain were CD3+ CD4- CD8- and CD3+ CD4+ T-cells. The expression of endothelial cell (EC) adhesion molecules increased, while that of tight and adherents junction proteins decreased, providing the molecular precondition for T-cell recruitment to ECs and paracellular migration into the brain. The fusion of lymphocytes and EC membranes and transcellular migration of CD3-related gold particles were captured, suggesting enhancement of transcytosis in the brain ECs. Exogenous fluorescent tracers and endogenous IgG and albumin leakage also revealed an impairment of transcellular pathway in the ECs. FTY720 significantly alleviated brain calcification, probably by reducing T-cell infiltration, modulating neuroinflammation and ossification process, and enhancing the autophagy and phagocytosis of CNS-resident immune cells. This study clearly demonstrated CNS-infiltrating T-cells to be associated with the progression of brain calcification. Impairment of blood-brain barrier (BBB) permeability, which was closely related to T-cell invasion into the CNS, could be explained by the BBB alterations of an increase in the paracellular and transcellular pathways of brain ECs. FTY720 was found to be a potential drug to protect patients from PFBC-related lesions in the future.

Abstract
BACKGROUND Previous antibiotic exposure is an important risk factor for invasive fungal infection (IFI). Antibiotic overexposure is common in lower-income countries; however, multi-centre studies concerning IFI in relation to antibiotic exposure are scarce. AIM This prospective, multi-centre matched case-control study explored the correlation of IFI and antibiotic exposure in very preterm infants or very-low-birthweight infants admitted to 23 tertiary hospitals in China between 2018 and 2021. METHODS Using a 1:2 matched design for gestational age, birth weight and early-onset sepsis (yes/no), the risk factors between infants diagnosed with IFI and infection-free controls were compared. The antibiotic use rate (AUR) was calculated using calendar days of antibiotic therapy in the 4 weeks preceding IFI onset divided by onset day of IFI. FINDINGS In total, 6368 infants were included in the study, of which 90 (1.4%) were diagnosed with IFI. Median AUR, length of antibiotic therapy (LOT) and days of antibiotic therapy (DOT) within the 4 weeks preceding IFI onset were 0.90, 18 days and 30 days, respectively. Multi-variate analysis showed that a 10% increase in AUR, each additional day of DOT and LOT, and each additional day of third-generation cephalosporins and carbapenems were notably associated with IFI. CONCLUSION Prolonged antibiotic therapy is common before the onset of IFI, and is an important risk factor, especially the use of third-generation cephalosporins and carbapenems. Antibiotic stewardship should be urgently developed and promoted for preterm infants in order to reduce IFI in lower-income countries such as China.

Abstract
Objective This study aims to summarize the clinical characteristics of one teenager with autoimmune polyglandular syndrome (APS) type III C + D to improve the understanding of APS III C + D and its effect of thyroid function. Methods This article reported the clinical manifestations, laboratory examinations, treatment methods, and outcomes of an adolescent with anemia admitted to the Pediatrics Department of Tianjin Medical University General Hospital in July 2020 and reviewed the literature. Results A girl, aged 13 years and 1 month, was admitted to the hospital due to anemia for more than 4 years and episodic abdominal pain for 1 week. Four years ago, the girl went to a local hospital for "vitiligo", and a routine blood test revealed anemia. The lowest hemoglobin (HGB) was 61 g/L, and the blood test revealed iron deficiency anemia. She had no menstrual cramps for 2 months. Urine routine showed protein 3+∼4+ and 258 red blood cells (RBCs)/high-power field. Urine protein was 3,380 mg/24 h. Free thyroxine was low, thyroid-stimulating hormone was >100 uIU/ml, thyroid peroxidase antibody was >1,000 IU/ml, and thyroglobulin antibody and thyrotropin receptor antibody were negative. Pituitary magnetic resonance imaging showed a mass in the sellar region with a uniform signal and a maximum height of about 15.8 mm. The result of the antinuclear antibody was 1:80 homogeneous type, and anti-dsDNA and anticardiolipin antibodies IgA and IgM were slightly higher. Thyroxine and iron were given for 1 month, menstruation resumed, and urine protein and RBC count decreased. After 5 months of treatment, free thyroid function, HGB, RBCs in urine, and pituitary returned to normal. Later, a renal biopsy showed changes in focal proliferative glomerulonephritis, and the girl was diagnosed with lupus glomerulonephritis type III. After 3 days of shock therapy with methylprednisolone, prednisone, mycophenolate mofetil, and other treatments were administrated for 1 year. At the time of writing, urine protein was 280 mg/24 h. Conclusion Co-occurrence of Hashimoto's thyroiditis, vitiligo, anemia, pituitary hyperplasia, and lupus nephritis is rare. It is very important to pay attention to the screening of thyroid function.

Abstract
Cerebral ischemia reperfusion injury (CIRI) is still a serious problem threatening human health. Salidroside (SAL) is a natural phenylpropanoid glycoside compound with antioxidant, anti-inflammatory, and anti-ischemic properties. This study investigated the protective mechanism of SAL on middle cerebral artery occlusion (MCAO)- and oxygen-glucose deprivation/reoxygenation (OGD/R) model-induced CIRI via regulating the nuclear factor erythroid 2-related factor 2 (Nrf2)/thioredoxin 1 (Trx1) axis. The results indicated that SAL (50 mg/kg or 100 mg/kg, intraperitoneal injection) not only effectively alleviated infarction rate, improved histopathological changes, relieved apoptosis by strengthening the suppression of cleaved caspase-3 and Bax/Bcl-2 proteins and decreased malondialdehyde (MDA) formation, but also increased superoxide dismutase (SOD) and catalase (CAT) activities and upregulated the expressions of Nrf2 and Trx1 on MCAO-induced CIRI rats. SAL also efficiently inhibited apoptosis and decreased oxidative stress in OGD/R-stimulated PC12 cells. Furthermore, blocking the Nrf2/Trx1 pathway using tretinoin, an Nrf2 inhibitor, significantly reversed the protective effect of SAL on OGD/R-induced oxidative stress. Moreover, SAL reduced the expression of apoptosis signal-regulating kinase-1 (ASK1) and mitogen-activated protein kinase (MAPK) family proteins. These results demonstrated that SAL inhibited oxidative stress through Nrf2/Trx1 signaling pathway, and subsequently reduced CIRI-induced apoptosis by inhibiting ASK1/MAPK.

Abstract
Being the most common form of dementia, Alzheimer's disease (AD) has a series of modifiable risk factors, including metal ions represented by aluminium. Aluminium (Al) exhibits its neurotoxic effects, especially mainly by affecting amyloid-β protein (Aβ) aggregation and Tau hyperphosphorylation. As reported in our previous study, the combination of Alpinia Oxyphylla Fructus and Schisandra Chinensis Fructus (AS) had a neuroprotective effect. This study aimed to evaluate the anti-AD effect of AS and the mechanism by which AS reduces the neurotoxic effect of Al. Firstly, we used aluminium-maltol (Al(mal)3) to construct a mouse model of AD and performed oral administration of AS, followed by behavioral experiments, and we collected the mouse brain for immunohistochemistry analysis. In vivo results showed that AS significantly improved Al-induced cognitive decline in mice, and reduced the levels of Aβ1-42 and P-Tau in the brain, which further proved the anti-AD effect of AS. Then, in order to explore the mechanism by which AS reduced Aβ1-42, Al-induced PC12 cells were used for the in vitro experiments. Compared with other ratios, the ratio of Alpinia Oxyphylla Fructus: Schisandra Chinensis Fructus (AO:SC) = 1:2 could better improve the cell viability and reduce the Aβ1-42 level. According to western blot and quantitative real-time polymerase chain reaction (qPCR) results, AS ameliorated the pathological process by downregulating the expression of β-secretase (BACE1), rather than by reducing the expression of amyloid precursor protein (APP) or Tau. These results suggest that AS ameliorated Al-induced AD by affecting the expression of BACE1 and reducing the level of Aβ1-42, thereby exerting a neuroprotective effect. Combined with previous studies, this study shows that AS has potential for further research and development in AD treatment.

Abstract
The conversion of white adipocytes into brown adipocytes improves their thermogenesis and promotes energy consumption. Epigenetic modifications affect related genes and interfere with energy metabolism, and these are the basis of new ideas for obesity treatment. Neonatal mice show high levels of DNA hypermethylation in white adipose tissue early in life and low levels in brown adipose tissue. Thus, we considered that the regulation of DNA methylation may play a role in the conversion of white adipose to brown. We observed growth indicators, lipid droplets of adipocytes, brown fat specific protein, and miRNA-133a after treatment with 5-Aza-2'-deoxycytidine. The expression of Prdm16 and Ucp-1 in adipocytes was detected after inhibiting miRNA-133a. The results showed a decrease in total lipid droplet formation and an increased expression of the brown fat specific proteins Prdm16 and Ucp-1. This study indicated that 5-Aza-2'-deoxycytidine promotes white adipocyte browning following DNA demethylation, possibly via the modulation of miR-133a and Prdm16.

Abstract
Based on the current results, they showed that Schisandra chinensis lignans (SCL) ameliorated depressive-like behaviors in chronic unpredictable mild stress (CUMS) mice, alleviated neuroinflammation, and improved neuronal injury. This study aimed to explore whether SCL exerted antidepressant effects through inhibiting neuroinflammation, in turn improving neuronal injury. In vitro studies revealed that SCL blocked lipopolysaccharide-increased BV2 microglial M1 but promoted the M2 phenotype. The BV2-N2a interaction model suggested that increasing the M2 phenotype of BV2 played neuroprotective effects. The current studies demonstrated that SCL up-regulated the expression of CUMS- and LPS-decreased cannabinoid receptor type-2 (CB2R) mRNA. In vitro studies showed that the transfection of BV2 with siCrn2 blocked the SCL-increased M2 phenotype via the inactivating signal transducer and activator of transcription 6 (STAT6) pathway, further decreasing the viability of N2a cells. Finally, the possible pharmacodynamic compounds, γ-schisandrin and schisantherin A, were indicated by AutoDuck analysis. Overall, our study showed that SCL promoted microglia polarization toward the M2 phenotype, in turn exerting neuroprotective effects by activating CB2R-STAT6 signaling further to play antidepressant roles.

Abstract
The present study aimed to evaluate the antidepressant-like effect of essential oils from Schisandra chinensis (Turcz.) Baill. (SEO) and its possible mechanisms of SEO. The behavioral despair mouse model in vivo and H2O2-induced PC12 cells model in vitro were employed. And the potential effective components were identified by the spectrum-effect relationships analysis. SEO significantly decreased the immobility time in the forced swimming test and tail suspension test, which indicated a promising antidepressant-like effect of SEO in depressed mice. The decreased levels of SOD, GSH, and CAT, and increased levels of MDA were significantly reversed by SEO treatment, which showed good antioxidant activities both in vitro and in vivo. Besides, SEO significantly promoted the nuclear translocation of Nrf2 and the expression of HO-1 in depressed mice and H2O2-induced PC12 cells. The histopathological examination results showed a potential neuronal protective effect of SEO in the hippocampus and cortex. Furthermore, the upregulation of PI3K/AKT/GSK3β signaling was observed after SEO treatment in the H2O2-induced PC12 cells. Additionally, based on the spectrum-effect relationship analysis, 9 peaks were identified as positively correlated with the antioxidant activity of SEO. These results suggested that SEO promoted Nrf2/HO-1 pathway to improve the oxidative stress status and exerted the antidepressant-like effects.

Abstract
BACKGROUND CLDN encodes a member of the claudin family. Claudin is a tight junction protein that is mainly involved in cell migration. Claudin family is of interest as a potential therapeutic target. Claudin18.2 is one of its important isoforms and is mainly expressed in the stomach. Its expression and prognosis in lung adenocarcinoma remain unknown. The aim of this study was to investigate the correlation between CLDN18 and claudin18.2 expression and prognosis in lung adenocarcinoma. METHODS Two cohorts were introduced in this study: one from The Cancer Genome Atlas (TCGA) CLDN18 mRNA public data (TCGA-LUAD, N = 551); the other from 1079 cases of lung adenocarcinoma diagnosed at the Fourth Hospital of Hebei Medical University, China, with immunohistochemical (IHC) detection of claudin18.2 in tissue microarrays. the IHC-positive cases were again verified by fluorescence in situ hybridization (FISH). RESULTS The mRNA expression of CLDN18 was significantly lower in lung adenocarcinoma tissues than in normal lung tissues (P < 0.05). Among 1079 Chinese lung adenocarcinoma cases, the overall positive rate of IHC for Claudin18.2 was 7.78% (84/1079). Among those positive for IHC, the positive rate of FISH was 11.9% (10/84), which accounted for 0.9% of the total number of cases (10/1079). To explore the best scoring scheme for Claudin 18.2, we used a four-group (IHC4) and two-group (IHC2) scoring method for evaluation. We found that IHC4 better explained Claudin 18.2 expression and helped us to find specific differences in clinical factors for weak, moderate and strong Claudin 18.2 expression. This difference was not discernible in the IHC2 score. By survival analysis, we found that Claudin 18.2 (IHC4) was able to stratify the prognosis of lung adenocarcinoma patients, with strongly positive patients having a better prognosis than the other subgroups (p < 0.05). We also found that patients with EGFR wild type or PD-L1 < 1% accompanied by strong positive claudin18.2 had a significantly better prognosis than other subgroups (P < 0.05). CONCLUSION Claudin18.2 (IHC4) better reveals the clinical and prognostic characteristics of patients with lung adenocarcinoma. Patients with EGFR wild type and PD-L1 < 1% have a better prognosis and partially overlap with claudin18.2 expression, so claudin18.2 may also be an important biomarker for lung adenocarcinoma testing, which is particularly important for EGFR wild type and PD-L1 < 1%.

Abstract
The detection of tumor markers in blood samples with high efficiency and sensitivity is in urgent need. In this work, a one-step quantitative detection assay for alpha fetal protein (AFP) based on gold microelectrode which is denoted as AuμE through square wave voltammetry using [Fe(CN)6]3-/4- as mediator was developed. As the biorecognition element of the assay, sulfydryl-modified AFP aptamer could be directly conjugated onto the surface of the AuμE, which could capture AFP with high specificity, and this attachment would cause the decrease of the capacitive current of the cyclic voltammetry due to the reduction of the active area of the electrodes. Under the optimized conditions, the AuμE aptasensor exhibited a linear detection range for AFP from 10-10 to 10-7 g/mL (S = 7.6 nA/dec, R2 = 0.991), and the detection limit is 2.5 × 10-11 g/mL. The AuμEs aptasensor demonstrates good selectivity against other types of proteins and small molecules, and has good reproducibility. The real blood samples were used for detection of AFP using the AuμEs aptasensor, the results agree well with those provided by the hospital through electrochemiluminescence method. Herein, the proposed one-step detection assay has a great application potential in point-of-care clinical diagnostics.

Abstract
Background Immunotherapy has proven to be an emerging treatment for non-small-cell lung cancer in recent years. Notably, smokers show higher programmed cell death ligand-1 (PD-L1) expression and better responses to PD-1/PD-L1 inhibitors than nonsmokers. Genome-wide association studies show that the CHRNΑ5 encoding α5-nicotinic acetylcholine receptor (α5-nAChR) is especially relevant to lung cancer and nicotine dependence. Jab1 is a key regulatory factor and promotes the stabilization of PD-L1. Our previous study reported that α5-nAChR mediates lung adenocarcinoma (LUAD) epithelial-mesenchymal transition (EMT) and metastasis via STAT3/Jab1. However, the link between α5-nAChR and PD-L1 is unclear in LUAD. Methods We used various bioinformatics databases to analyze the expression of related genes and their correlations. Expression and clinicopathologic significance of α5-nAChR and PD-L1 were detected by immunohistochemistry in a tissue microarray. α5-nAChR regulated LUAD cell immune escape by targeting the STAT3/Jab1-PD-L1 signalling by Western-blotting and ChIP in vitro. We used T cell coculture, flow cytometry, ELISA, CCK8 assay and crystal violet staining to detect the expression of regulatory T cell (Tregs), IFN-γ, IL-2 and the ability of T cell-mediated tumour cell killing respectively. IF assays were performed in both cancer cells and tumour xenograft paraffin sections to analyze the protein expression. The in vivo experiments in mouse model were performed to show the α5-nAChR-mediated immune escape via PD-L1 pathway. Results The expression of α5-nAChR was correlated with PD-L1 expression, smoking status and lower survival of LUAD in vivo. In vitro, the expression of α5-nAChR mediated phosphorylated STAT3 (pSTAT3), Jab1 and PD-L1 expression. STAT3 bound to the Jab1 or PD-L1 promoter and mediated PD-L1 expression. Jab1 stabilized PD-L1 expression in LUAD cells. Furthermore, in primary T cell cocultured system, downregulation of α5-nAChR suppressed the function of CD4+CD25+FOXP3+ Tregs, enhanced IFN-γ secretion, and increased T cell-mediated killing of LUAD cells. In the Jurkat T cells and LUAD cells coculture assay, inhibition of α5-nAChR increased IL-2 secretion. In tumour xenograft tissues, α5-nAChR expression was related to PD-L1, Jab1, pSTAT3, CD4 and granzyme B expression (GB). Conclusions Our results suggest that the novel α5-nAChR/STAT3-Jab1-PD-L1 axis is involved in LUAD immune escape, which could lead to potential therapeutic strategies for cancer immunotherapy.

Abstract
BACKGROUND Wei-Tong-Xin (WTX) is a traditional Chinese medicine (TCM) that has been screened and improved in accordance with the famous ancient Chinese formula "Wan Ying Yuan". It has been shown to be clinically effective in treating gastric dysmotility, but its underlying molecular mechanism remains unclear. PURPOSE This study primarily dealt with the effects and mechanisms of WTX on functional dyspepsia (FD) induced by chemotherapeutic drug cisplatin (CIS). METHODS Firstly, the UPLC fingerprint and multi-component determination of WTX were established. In vivo, gastrointestinal motility of mice was detected by charcoal propulsion test. Besides, H&E, western blot and qRT-PCR were performed to evaluate the occurrence of gastric antral inflammation. ROS-DHE staining was used to detect ROS levels. Further, the gut microbiota were subjected to sequencing by 16S rRNA, and the levels of bacterial metabolites short-chain fatty acids (SCFAs) and lipopolysaccharide (LPS) were detected by GC-MS and Limulus kits, respectively. The levels of GLP-1 in gastric antrum were assessed by ELISA kits. Finally, siRNA-FFAR2 experiment was performed in Raw 264.7 cells. RESULTS 23 common peaks were obtained from the UPLC fingerprint, and the content of 10 target components was determined. WTX increased the relative abundance of Firmicutes and decreased the number of Verrucomicrobia, accompanied by changes in the levels of SCFAs and LPS. By mediating the expression changes of free fatty acid receptor 2 (FFAR2) and toll-like receptor 4 (TLR4), WTX inhibited the phosphorylation of nuclear factor-κB (NF-κB), JNK and P38, decreased the levels of IL-1β, inducible nitric oxide synthase (iNOS) and ROS, increased the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), IL-4 and arginase-1 (Arg-1). Decreased expressions of glucagon-like peptide 1 (GLP-1) induced by WTX promoted gastric motility in FD mice. In vitro, siRNA-FFAR2 of Raw 264.7 cells eliminated the effects of WTX on TLR4 signaling pathway. CONCLUSIONS In this study, the chemical profile of WTX was first reported. Based on remodeling the gut microbiota structure and adjusting the levels of metabolites (SCFAs and LPS), WTX inactivated the TLR4/MyD88 signaling pathway to inhibit the occurrence of gastric antral inflammation, which reversed the inhibitory effect of GLP-1 on gastric motility, and improved CIS-induced FD symptoms.

Abstract
OBJECTIVE To explore the role of vasohibin-2 (VASH2) in regulation of proliferation and metastasis of cervical cancer cells. METHODS We analyzed the differentially expressed genes between cervical cancer cells with flotillin-1 overexpression and knockdown by RNA-seq combined with analysis of public databases. The expression levels of VASH2 were examined in normal cervical epithelial cells (HcerEpic), cervical cancer cell lines (HeLa, C-33A, Ca ski, SiHa and MS751) and fresh cervical cancer tissues with different lymph node metastasis status. We further tested the effects of lentivirus-mediated overexpression and interference of VASH2 on proliferation, migration, invasion and lymphatic vessel formation of the cervical cancer cells and detected the expression levels of key epithelial-mesenchymal transition (EMT) markers and TGF-β mRNA. RESULTS RNA-seq and analysis of public databases showed that VASH2 expression was significantly upregulated in cervical cancer cells exogenously overexpressing flotillin-1 (P < 0.05) and downregulated in cells with flotillin-1 knockdown (P < 0.05), and was significantly higher in cervical cancer tissues with lymph node metastasis than in those without lymph node metastasis (P < 0.01). In cervical cancer cell lines Ca Ski, SiHa, and MS751 and cervical cancer tissue specimens with lymph node metastasis, VASH2 expression was also significantly upregulated as compared with HcerEpic cells and cervical cancer tissues without lymph node metastasis (P < 0.05). Exogenous overexpression of VASH2 significantly promoted proliferation, migration, invasion and lymphatic vessel formation of cervical cancer cells, whereas these abilities were significantly inhibited in cells with VASH2 knockdown (P < 0.05). The cervical cancer cells overexpressing VASH2 showed significant down- regulation of e-cadherin and up- regulation of N-cadherin, Vimentin and VEGF-C, while the reverse changes were detected in cells with VASH2 knockdown (P < 0.05). TGF-β mRNA expression was significantly up-regulated in cervical cancer cells overexpressing VASH2 and down-regulated in cells with VASH2 knockdown (P < 0.001). CONCLUSION Flotillin-1 may participate in TGF-β signaling pathway-mediated EMT through its down-stream target gene VASH2 to promote the proliferation, migration, invasion and lymphatic vessel formation of cervical cancer cells in vitro.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The prescription of Wei-Tong-Xin (WTX) is improved based on the prescription "Wanyingyuan", a famous decoction documented in the book of Huatuozhongzangjing in the Han dynasty. Many years of clinical verification have demonstrated that WTX can be used to treat gastrointestinal diseases, especially gastric ulcer (GU). However, the potential pharmacological mechanism is undefined. AIM OF THE STUDY This research was conducted to explore the pharmacological mechanisms under the consideration of the therapeutical effect of WTX against GU by combining the network pharmacology strategy and in-vivo verified experiments. MATERIALS AND METHODS A prediction network describing the relationship between WTX and GU was established based on information collected from multiple databases. Then, the intersecting protein-protein interaction (PPI) network of the drug-disease overlapping gene targets was constructed, and several key targets related to both WTX and GU were obtained. Besides, the Gene Ontology (GO) biological enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to investigate the key target genes and pathways of WTX against GU. Then, the candidate targets and signaling pathways of network pharmacology were validated in a rat model of GU induced by indomethacin following the results and available proof. RESULTS There are 243 targets obtained from the 65 active ingredients in WTX, and 1362 disease targets related to GU were identified. Then, 6 key targets were determined with the PPI interaction network, which was structured from 126 overlapping gene targets. GO and KEGG analyses revealed that the phosphoinositide-3-kinase/protein kinase B (PI3K/AKT) signaling pathway might play a crucial role in the therapeutic mechanism of GU. In vivo verified experiments, WTX significantly reduced the ulcer area and improved the histopathological appearance of gastric tissues. Moreover, down-regulated the protein levels of IL6, TNF-α, and Caspase 3 in the gastric tissues while up-regulating the expression of p-PI3K, p-AKT, p-P53, and VEGFA compared to the model group. CONCLUSION WTX, an ancient traditional Chinese medicine (TCM) compound prescription, may affect the inflammatory response and apoptosis process by regulating PI3K/AKT signaling pathway and related gene targets. Therefore, it is an effective drug candidate for the modern treatment of GU.

Abstract
AIMS Intratumoural heterogeneity (ITH) has been implicated in tumour growth and progression as well as therapy resistance. However, the extent of ITH of somatic copy number alterations (ITH-SCNAs) as a result of tumour evolution and its influence on clinical outcomes in diffuse glioma (DG) remain poorly understood. METHODS We used an integrated computational method to infer clonal and subclonal SCNAs in 760 untreated primary DGs from The Cancer Genome Atlas. ITH-SCNAs at the genome-wide, peak (region with recurrent SCNAs) and gene level were calculated. We used the Kaplan-Meier estimators and Cox proportional hazards models to examine the associations of ITH-SCNA with patient outcomes. An independent cohort of 243 patients with paired initial and recurrent tumours from the Glioma Longitudinal Analysis Consortium was used for validation. RESULTS DGs showed widespread ITH-SCNA, with a median of 25.5% of SCNAs identified as subclonal. We found that clonal SCNA burden had stronger prognostic power than total SCNAs in IDH-mutant astrocytoma. Coamplifications of receptor tyrosine kinases (RTKs) tended to be subclonal, and subclonal RTK amplification was significantly associated with high tumour proliferative potential and unfavourable clinical outcomes in IDH-wild-type glioblastoma. In addition, we found that the prognostic values of the peak-level SCNAs were related to their mutated clonal architecture, from which three clonality-dependent prognostic patterns of SCNAs were proposed, including clonal-dominant, subclonal-dominant and clonality-independent schemas. CONCLUSIONS The systematic analysis of ITH-SCNAs in large cohorts of DGs highlighted the importance of considering the clonality of SCNA in discovery of tumour prognostic markers.

Abstract
Snake venoms are mainly composed of proteins and peptides (venom toxins). The venom transcriptomes and proteomes have been extensively investigated; however, venom toxin-toxin interactions remain poorly characterized. We detected the interaction of venom Asp49-PLA2 and 3FTx using biochemical and computational approaches. A stable structure of Asp49-PLA2-3FTx was identified, and the interface of Asp49-PLA2 and 3FTx was analyzed. The approaches will shed light on understanding the venom complexity and deciphering the synergistic effects of venom toxins.

Abstract
BACKGROUND Only one additional specific SNP in blaTEM-135 in penicillinase-producing Neisseria gonorrhoeae (PPNG) isolates is required for TEM-135 to evolve into an ESBL that is capable of degrading all extended-spectrum cephalosporins (ESCs). METHODS Identification of the blaTEM-135 gene was achieved by performing a mismatch amplification mutation assay PCR. PPNG isolates were then genotyped using MLST and N. gonorrhoeae multiantigen sequence typing (NG-MAST) techniques. Finally, phylogenetic analyses based on MLST and NG-MAST were performed on all of the PPNG isolates, and genogroups were classified according to the phylogenetic relatedness on the basis of each MLST and NG-MAST gene typing and the blaTEM allele varieties. RESULTS Among the 197 PPNG isolates, one (0.5%) isolate possessed the blaTEM-220 allele, 90 (45.7%) possessed the blaTEM-135 allele, and 106 (53.8%) possessed the blaTEM-1 allele. Among the blaTEM-135-carrying PPNG isolates, MLST ST8109 (n = 30) and NG-MAST ST12199 (n = 5), ST12754 (n = 5) and ST15073 (n = 5) were the most prevalent in the Shandong province of China. The phylogenetic analyses revealed that MLST ST8109, ST8140 and ST14417, mainly carrying the blaTEM-135 allele, belonged to the same genogroup, G1, while NG-MAST ST12199 and ST15073, mainly carrying the blaTEM-135 allele, belonged to the same genogroup, Ga. CONCLUSIONS This study has shown that the molecular epidemiology of PPNG isolates carrying the blaTEM-135 allele in Shandong has a dynamically changing status. Therefore, it is very pressing to continuously monitor the prevalence and mutation of the blaTEM-135 allele and the genetic epidemiology of PPNG isolates carrying the blaTEM-135 allele in this district.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) is suggested to be implicated in the development of cardiometabolic diseases. We conducted a Mendelian randomization (MR) study to assess potential causality for associations of RA with the risk of cardiometabolic diseases, including type 2 diabetes (T2D), coronary artery disease (CAD), and ischaemic stroke. METHOD Seventy independent single-nucleotide polymorphisms (SNPs) associated with RA were identified as instrumental variables from a genome-wide association study (GWAS) of 58 284 European subjects. Summary-level data for the associations of the 70 genetic variants with T2D, CAD, and ischaemic stroke were taken from three GWASs with a total of 1 529 131 participants. Inverse-variance weighted (IVW) MR was used in the main analyses. RESULTS The main IVW MR analysis showed that genetically determined RA was associated with higher risks of T2D [odds ratio (OR): 1.04, 95% confidence interval (CI) 1.02-1.05; p < 0.001] and CAD (OR: 1.02, 95% CI 1.00-1.03; p = 0.012), but not ischaemic stroke (OR: 1.00, 95% CI 0.99-1.02; p = 0.961). Sensitivity analyses with multiple MR methods confirmed these associations. MR-Egger regression showed no evidence of pleiotropy in the association between genetically determined RA and the risk of T2D, CAD, and ischaemic stroke. Leave-one-out sensitivity analysis showed that the association between genetically determined RA and the risk of T2D, CAD, and ischaemic stroke was not driven by any individual SNP. CONCLUSION Genetically determined RA was associated with increased risks of T2D and CAD, suggesting that RA plays a crucial role in the pathogenesis of T2D and CAD.

Abstract
A pair of differential epimers with opposite C-7 configurations, crenatosides A and B (1 and 2), and 10 known phenylethanoid glycosides (PhGs) (3-12) were obtained from the succulent stem of Cistanche tubulosa. The structures were elucidated based on extensive spectral data (UV, IR, 1D and 2D NMR, HR-ESIMS), which are first reported natural products with unique glycoside structures. After acid hydrolysis, the configuration of the sugar was determined by comparing it with the normative sugar by HPLC. The absolute configurations of both compounds were determined by ECD spectrum analysis. All the obtained compounds were examined for their inhibitory effect on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in mouse microglial cells (BV-2 cells), and compounds 1 and 2 showed potent inhibition on NO production with IC50 values of 5.62 μM and 6.30 μM, respectively.

Abstract
Background Oseltamivir resistance in influenza virus (IFV) has been of widespread concern. An increase in the frequency of viruses with reduced inhibition was observed. Whether oseltamivir is effective is uncertain. We conducted this study to understand the real-world situation in northern China and the clinical efficacy for patients with IFV infection after the use of oseltamivir. Methods The longitudinal study was performed on influenza-like illness (ILI) cases in a tertiary general hospital in Beijing, China during the flu season of 2018–2019. All ILI cases (≥18 years) were recruited into the study. We analyzed the effect of the oseltamivir therapy on the number of clinic visits, hospitalization frequency, and the duration of fever and cough. Results A total of 689 ILI patients were recruited in this study with 355 in the oseltamivir therapy group and 334 in the supportive therapy group. Among the ILI patients, 388 patients were detected for IFV infection (364 IFV-A and 24 IFV-B) and divided into two groups with or without the oseltamivir therapy (302 vs. 86). There were no significant differences in the basic characteristics between the oseltamivir and supportive therapy groups in the ILI patients or in the IFV positive patients (all p < 0.05). After adjusting for the potential confounders, oseltamivir therapy reduced the times of clinic visits in the ILI and IFV positive patients (p = 0.043 and p = 0.011). No effectiveness with oseltamivir therapy was observed in the outcomes of hospitalization frequency, and the duration of fever and cough. Conclusion Oseltamivir use may reduce the times of clinic visits. However, we did not observe the differences in the duration of fever, cough, and the frequency of hospitalization between oseltamivir therapy and supportive therapy.

Abstract
BACKGROUND Silibinin, a major component of milk thistle extract silymarin, promotes hypoglycemia by activating estrogen receptor (ER) α and β-mediated pathways in pancreatic β-cells. Glucagon-like peptide-1 (GLP-1) is the enteroendocrine peptide produced in L-cells, and it controls glucose homeostasis through multiple pathways. The effect of silibinin on L-cell mass and function is still unknown. PURPOSE The protective effect of silibinin on palmitate (PA)-treated intestinal L-cell line GLUTag cells and the SHRSP•Z-Leprfa/Izm-Dmcr (SP•ZF) diabetic rat model was investigated in current study. METHODS After pre-incubation with 50 μM silibinin for 4 h, GLUTag cells were treated with 0.125 mM PA. MTT, Annexin V/PI apoptosis, Hoechst 33342 staining, western blot, DCFH-DA, GLP-1 ELISA, qRT-PCR and immunofluorescence analyses were undertaken to determine ER-dependent protection of silibinin against PA-induced cellular damage. The differential protein expression of GLUTag cells under different treatments was examined by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). The SP•ZF diabetic rat model was chosen for in vivo study. After 4 weeks of gastric gavage with 100 or 300 mg kg-1 of silibinin, the physiological indexes of the rats were measured. Cells expressing GLP-1, 8‑hydroxy-2'-deoxyguanosine (8-OHdG), ERα, and/or ERβ in duodenum tissues were detected by immunofluorescence. RESULTS The current study showed that the GLUTag cells preincubated with silibinin activated the transcription factor nuclear erythroid-2 like factor-2 (Nrf2)-antioxidant pathway, reduced reactive oxygen species (ROS) generation, and improved cell survival and GLP-1 content, while the antioxidative effect of silibinin was blocked by the selective ERα antagonist MPP or ERβ antagonist PHTPP in GLUTag cells. Our proteomics data further revealed that ERα or β inactivation reduced glutathione peroxide and proteins associated with endocytosis and reproduction, thus at least partially reversing the protective effect of silibinin. SP•ZF rats received silibinin treatment showed increased serum GLP-1 content and improved glucose homeostasis. Furthermore, silibinin upregulated ERα and β levels and reduced the level of 8-OHdG in GLP-1-positive cells. CONCLUSIONS Our study showed that silibinin improved L-cell mass and function through an ER-mediated antioxidant pathway, and the proteomics analysis revealed for the first time the differential regulation of proteins by PA and silibinin in GLUTag cells.

Abstract
Telomere maintenance mechanisms (TMMs) rescue cells from telomere crisis, endow cells immortal property, stabilize genomic integrity. However, TMM-associated molecular profiles and their clinical outcomes in cancer remain elusive. Here, we performed a pan-cancer and integrated analysis of TMM gene expression profiles from 10,107 unique samples with clinicopathological, molecular and outcome features across 7 malignancies from the same microarray platform (Affymetrix GPL570 platform). This resource was divided into Case-Control datasets for obtaining dysregulated TMM genes and Survival datasets for evaluating clinical outcomes. Multidimensional data from The Cancer Genome Atlas (TCGA) were used to elucidate associations between TMM dysregulation and survival, genomic instability. Our results demonstrated that TMMs had a consistent dysregulation spectrum across cancers, based on which we developed the TMM-dysregulation signature TMScore that was positively associated with various tumor adverse features. Two opposite prognostic patterns of TMScore independent of clinicopathological and molecular characteristics were identified, which might be explained by genomic instability: breast and lung cancer patients with elevated TMScore had inferior outcomes, suggesting TMScore-related genes as potential therapeutic targets, on the contrary, colon and stomach cancer patients had superior outcomes. Most important, the prognostic value of TMScore was still significant regardless of whether patients had received adjuvant therapy, which was valuable for discriminating non-responders from responders, and could predict the effectiveness of adjuvant therapy. In summary, our resources delineate TMMs dysregulated landscape across cancers, shed light on the impact of TMMs dysregulation on patient outcomes and adjuvant therapy, and provide novel therapeutic opportunities for cancer treatment.

Abstract
Herein, we aim to investigate the effect of Alpinae Oxyphyllae Fructus (AOF) on cognitive impairments and neuroinflammation in a lipopolysaccharide (LPS)-induced models of AD. Mice were injected intracerebroventricularly with LPS, and then administrated AOF using a gavage for 6 weeks. Spatial working memory was assessed using the Y-maze and Morris water maze test, whereas the levels of PI3K, AKT, p-AKT, p-GSK3β, GSK3β, NF-κB, IL-1β, IL-6, and TNF-α were evaluated using western blot and ELISA assay. Our data showed that AOF was able to significantly alleviate the memory decline in LPS-induced AD mice. Moreover, AOF was able to protect neurons through the PI3K/AKT signaling pathway and significantly decrease NF-κB, IL-6, IL-1β, and TNF-α levels in the hippocampal and cortex tissues, which were reversed through the use of LY294002. Additionally, we discovered that AOF could significantly decrease the high expression of cytokines as well as the expression and translocation of NF-κB induced by LPS in PC12 cells. These results demonstrate the anti-neuroinflammatory effect of AOF in both cell and animal models of AD, thereby slowing down the process and development of the disease.

Abstract
The Qilianyu cluster of the Xisha (Paracel) Islands has one of the few remaining green turtle Chelonia mydas rookeries in the China region. Genetic samples were obtained from dead green turtle embryos and hatchlings salvaged from post-hatched nests at Middle Island (n = 3), North Island (n = 9) and South Sand (n = 1) of the Qilianyu cluster in 2017-2019. The ~800 bp mitochondrial DNA control region was sequenced from the samples, and 5 haplotypes were identified belonging to 2 documented clades (clades III and VIII), including 2 new haplotypes (CmP243.1 and CmP244.1) and 3 previously reported haplotypes (CmP18.1, CmP19.1, CmP20.1). These results were combined with previously published mtDNA data for the Qilianyu cluster and nearby (~93 km) Yongle Islands indicating a lack of differentiation based on truncated 384 bp control region sequences (exact test, p = 0.0997; FST = 0.015, p = 0.2760), to represent a single Xisha Islands rookery. The rookery at the Xisha Islands was significantly differentiated (p < 0.01) from all 19 management units (MUs) documented in the Indo-Pacific and Japan regions, supporting recognition of the Xisha Islands rookery as a new independent MU. The results will help inform national and international conservation action plans by China and the countries around the South China Sea to protect green turtles in the West Pacific Ocean.

Abstract
BACKGROUND Methazolamide (MTZ) has been occasionally linked to the lethal Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), which are associated with HLA-B*59:01. However, some MTZ-induced SJS/TEN (MTZ-SJS/TEN) cases are negative for HLA-B*59:01, implying that other genetic factors besides HLA-B*59:01 are contributing to MTZ-SJS/TEN. OBJECTIVES To comprehensively identify HLA and non-HLA genetic susceptibility to MTZ-SJS/TEN in Han Chinese. METHODS Eighteen patients with MTZ-SJS/TEN, 806 subjects of the population control and 74 MTZ-tolerant individuals were enrolled in this study. Both exome-wide and HLA-based association studies were conducted. Molecular docking analysis was employed to simulate the interactions between MTZ and risk HLA proteins. RESULTS We found a strong signal in the major histocompatibility complex region on chromosome 6 with 22 SNPs reaching exome-wide significance. Compared with MTZ-tolerant controls, a significant association of HLA-B*59:01 with MTZ-SJS/TEN was validated (odds ratio [OR] = 146.00, 95% confidence interval [CI]: 16.12-1321.98; P = 6.19 × 10-10 ). Moreover, 66.7% of MTZ-SJS/TEN patients negative for HLA-B*59:01 were carriers of HLA-B*55:02, while 2.7% of the tolerant individuals were observed with HLA-B*55:02 (OR = 71.00, 95% CI: 7.84-643.10; P = 1.43 × 10-4 ). Within HLA-B protein, the E45-L116 motif could completely explain the association of HLA-B*59:01 and HLA-B*55:02 with MTZ-SJS/TEN (OR = 119.33, 95% CI: 29.19-1227.96; P = 4.36 × 10-13 ). Molecular docking analysis indicated that MTZ binds more stably to the pocket of HLA-B*59:01 and HLA-B*55:02 than to that of non-risk alleles of HLA-B*40:01 and HLA-C*01:02. CONCLUSIONS This study confirmed the association of HLA-B*59:01 with MTZ-SJS/TEN and identified HLA-B*55:02 as a novel risk allele in Han Chinese with the largest sample size to date. Notably, the rs41562914(A)-rs12697944(A) haplotype, encoding E45-L116, is capable of serving as a powerful genetic predictor for MTZ-SJS/TEN with a sensitivity of 89% and specificity of 96%.

Abstract
Dissipation is vital to any cyclic process in realistic systems. Recent research focus on nonequilibrium processes in stochastic systems has revealed a fundamental trade-off, called dissipation-time uncertainty relation, that entropy production rate associated with dissipation bounds the evolution pace of physical processes [Phys. Rev. Lett. 125, 120604 (2020)PRLTAO0031-900710.1103/PhysRevLett.125.120604]. Following the dissipative two-level model exemplified in the same Letter, we experimentally verify this fundamental trade-off in a single trapped ultracold ^{40}Ca^{+} ion using elaborately designed dissipative channels, along with a postprocessing method developed in the data analysis, to build the effective nonequilibrium stochastic evolutions for the energy transfer between two heat baths mediated by a qubit. Since the dissipation-time uncertainty relation imposes a constraint on the quantum speed regarding entropy flux, our observation provides the first experimental evidence confirming such a speed restriction from thermodynamics on quantum operations due to dissipation, which helps us further understand the role of thermodynamical characteristics played in quantum information processing.

Abstract
The lunar nearside has been investigated by many uncrewed and crewed missions, but the farside of the Moon remains poorly known. Lunar farside exploration is challenging because maneuvering rovers with efficient locomotion in harsh extraterrestrial environment is necessary to explore geological characteristics of scientific interest. Chang'E-4 mission successfully targeted the Moon's farside and deployed a teleoperated rover (Yutu-2) to explore inside the Von Kármán crater, conveying rich information regarding regolith, craters, and rocks. Here, we report mobile exploration on the lunar farside with Yutu-2 over the initial 2 years. During its journey, Yutu-2 has experienced varying degrees of mild slip and skid, indicating that the terrain is relatively flat at large scales but scattered with local gentle slopes. Cloddy soil sticking on its wheels implies a greater cohesion of the lunar soil than encountered at other lunar landing sites. Further identification results indicate that the regolith resembles dry sand and sandy loam on Earth in bearing properties, demonstrating greater bearing strength than that identified during the Apollo missions. In sharp contrast to the sparsity of rocks along the traverse route, small fresh craters with unilateral moldable ejecta are abundant, and some of them contain high-reflectance materials at the bottom, suggestive of secondary impact events. These findings hint at notable differences in the surface geology between the lunar farside and nearside. Experience gained with Yutu-2 improves the understanding of the farside of the Moon, which, in return, may lead to locomotion with improved efficiency and larger range.

Abstract
The α5-nicotinic acetylcholine receptor (α5-nAChR) is closely associated with nicotine-related lung cancer, offering a novel perspective for investigating the molecular pathogenesis of this disease. However, the mechanism by which α5-nAChR functions in lung carcinogenesis remains to be elucidated. Lymphocyte antigen 6 (Ly6) proteins, like snake three-finger alpha toxins such as α-bungarotoxin, can modulate nAChR signaling. Ly6E, a member of the Ly6 family, is a biomarker of poor prognosis in smoking-induced lung carcinogenesis and is involved in the regulation of TGF-β1/Smad signaling. Here, we explored the underlying mechanisms linking α5-nAChR and Ly6E in non-small cell lung cancer (NSCLC). The expression of α5-nAChR was correlated with Ly6 expression, smoking status and lower survival in NSCLC tissues. In vitro, α5-nAChR mediated Ly6E, the phosphorylation of the TGF-β1 downstream molecule Smad3 (pSmad3, a key mediator of TGF-β1 signaling), the epithelial-mesenchymal transition (EMT) markers Zeb1, N-cadherin and vimentin expression in NSCLC cells. The downregulation of Ly6E reduced α5-nAChR, pSmad3, Zeb1, N-cadherin and vimentin expression. Functionally, silencing both α5-nAChR and Ly6E significantly inhibited cell migration compared to silencing α5-nAChR or Ly6E alone. Furthermore, the functional effects of α5-nAchR and Ly6E were confirmed in chicken embryo chorioallantoic membrane (CAM) and mouse xenograft models. Therefore, our findings uncover a new interaction between α5-nAChR and Ly6E that inhibits cancer cell migration by modulating the TGF-β1/Smad signaling pathway in NSCLC, which may serve as a novel target for therapeutic intervention.

Abstract
OBJECTIVES Coffee and tea intake might be associated with psychiatry diseases. However, it is unclear whether the effect of coffee/tea on anxiety and depression depending on the different types of proteins. DESIGN This was a cross-sectional study. SETTING Our datasets were downloaded from online. PARTICIPANTS Phenotypic and genotypic data for coffee intake(N=376,196) and tea intake (N=376,078) were derived from UK Biobank. GWAS data of proteins (N=1,537) from neurologically relevant tissues (brain, cerebrospinal fluid (CSF) and plasma) were obtained from a recently published study. MEASUREMENTS Multivariate linear analysis was then used to evaluate the potential interaction effect between coffee/tea intake and proteins polygenetic risk score (PRS) on the risks of anxiety and depression controlling for age, sex, Townsend deprivation index (TDI), smoke, drinking and education level. RESULTS 34 coffee intake-proteins interactions and 15 tea intake-proteins interactions were observed in anxiety individuals, such as coffee intake-c-Jun interaction (β=0.0169, P=4.131×10-3), coffee intake-Fas interaction (β=-0.0190, P=8.132×10-4), tea intake-sL-Selectin interaction (β=0.0112, P=5.412×10-3) and tea intake-IL-1F6 (β=0.0083, P=4.471×10-2). 25 coffee intake-proteins and 14 tea intake-proteins interactions were observed in depression individuals, including coffee intake- IL-1 sRI (β=0.0171, P=4.888×10-3) and coffee intake-NXPH1 interaction (β=0.0156, P=9.819×10-3), tea intake-COLEC12 interaction (β=0.0127, P=3.280×10-3), and tea intake-Layilin interaction (β=0.0117, P=7.926×10-3). CONCLUSIONS Our results suggested the important role of multiple proteins in neurologically relevant tissues in the associations between coffee/tea intake and psychiatry diseases, providing entry points to explore the mechanisms underlying anxiety and depression.

Abstract
OBJECTIVES Intracerebral hemorrhage (ICH) induced by diabetes results in further brain injury and nerve cell death. Bone marrow mesenchymal stem cell (BMSC) transplantation contributes to attenuating neurological deficits after ICH. This study investigated the mechanism of extracellular vesicles (EVs) derived from BMSCs in reducing neuroinflammation after diabetic ICH. METHODS BMSC-EVs were isolated and identified. The rat model of db/db-ICH was established and the model rats were administered with EVs. miR-183-5p expression in brain tissues of db/db-ICH rats was detected. The brain injury of db/db-ICH rats was evaluated by measuring neurobehavioral score, brain water content and inflammatory factors. BV2 cells were cultured in vitro to establish high-glucose (HG)-Hemin-BV2 cell model. The levels of reactive oxygen species (ROS) and inflammatory factors in BV2 cells were measured, and BV2 cell viability and apoptosis were assessed. The targeting relationship between miR-183-5p and PDCD4 was predicted and verified. The activation of PDCD4/NLRP3 pathway in rat brain tissues and BV2 cells was detected. RESULTS miR-183-5p expression was reduced in db/db-ICH rats brain tissues. BMSC-EVs ameliorated cranial nerve function, decreased brain water content and repressed inflammatory response by carrying miR-183-5p. BMSC-EVs mitigated HG-Hemin-BV2 cell injury, reduced ROS level and suppressed inflammatory response. miR-183-5p targeted PDCD4. PDCD4 promoted BV2 cell inflammation by activating the NLRP3 pathway. BMSC-EVs inhibited HG-Hemin-BV2 cell inflammation through the miR-183-5p/PDCD4/NLRP3 pathway, and inhibition of miR-183-5p reversed the protective effect of EVs. CONCLUSION BMSC-EVs carried miR-183-5p into db/db-ICH rat brain tissues and repressed the NLRP3 pathway by targeting PDCD4, thus alleviating neuroinflammation after diabetic ICH.

Abstract
AIM To investigate the diagnostic performance of the radiomics features of pericoronary adipose tissue (PCAT) in determining haemodynamically significant coronary artery stenosis as evaluated by fractional flow reserve (FFR). MATERIALS AND METHODS A total of 92 patients with clinically suspected coronary artery disease who underwent coronary computed tomography (CT) angiography (CCTA), invasive coronary angiography (ICA), and FFR examination within 1 month were included retrospectively, and 121 lesions were randomly assigned to the training and testing set. Based on manual segmentation of PCAT, 1,116 radiomics features were computed. After radiomics robustness assessment and feature selection, radiomics models were established using the different machine-learning algorithms. The area under the receiver operating characteristic (ROC) curve (AUC) and net reclassification index (NRI) were analysed to compare the discrimination and reclassification abilities of radiomics models. RESULTS Two radiomics features were selected after exclusions, and both were significantly higher in coronary arteries with FFR ≤0.8 than those with FFR >0.8. ROC analysis showed that the combination of CCTA and decision tree radiomics model achieved significantly higher diagnostic performance (AUC: 0.812) than CCTA alone (AUC: 0.599, p=0.015). Furthermore, the NRI of the combined model was 0.820 and 0.775 in the training and testing sets, respectively, suggesting the radiomics features of PCAT had were effective in classifying the haemodynamic significance of coronary stenosis. CONCLUSIONS Adding PCAT radiomics features to CCTA enabled identification of haemodynamically significant coronary artery stenosis.

OBJECTIVE To screen out high-risk groups of endocervical lesions, explore the effect of length of excision on margin status in women with abnormal endocervical curettage (ECC) and explore the role of ECC in the additional detection of high-grade squamous intraepithelial lesion or worse (HSIL+) under colposcopy and lesion-targeted biopsies. METHODS The study included 936 patients who underwent loop electrosurgical excision procedure (LEEP) for cervical lesions which were diagnosed by cervical biopsy and ECC at the cervical clinic of the First Affiliated Hospital of Chongqing Medical University from January 2014 and December 2018. The correlations among abnormal ECC, human papillomavirus (HPV) type, cytology, margin of excision, and age were analyzed by Pearson's χ2 test and multivariate logistic regression analysis. RESULTS Abnormal ECC was associated with HPV-16 infection (P<0.001), or HSIL cervical cytology or worse (P<0.001), or aged 50 years old or older (P<0.001). Abnormal ECC was associated with positive margin of excision (P<0.001). For patients with abnormal ECC, the length of excision was independent of margin status (P=0.762). Among all the 491 patients with HSIL+ diagnosed by either cervical biopsy or ECC, the additional detection rate of HSIL+ by ECC was only 8.76% (43/491). CONCLUSION In our study, ECC was recommended in women with HPV16 infection, HSIL cervical cytology or worse, aged 50 or older, or invisible transformation zone in colposcopy. At the same time, our results suggested that ECC abnormalities were associated with positive margin of excision. The data did not support performing a longer length of excision in patients with abnormal ECC, especially in women with fertility needs. In summary, patients with abnormal ECC should be given more attention and follow-up to avoid missing residual lesions.orse prognostic factor in breast cancer patients.

Abstract
Our study aimed to explore the impacts of liraglutide on brain dysfunction of type 2 diabetes mellitus. Rats in liraglutide treatment group were diabetic rats further received daily intraperitoneal administration of liraglutide for continuous 6 weeks. Body weight and blood glucose were measured weekly. Vascular structure changes in brain tissues were evaluated by Periodic acid-Schiff (PAS) staining. Angiopoietin-2 (ANG-2), high-mobility group box 1 (HMGB-1), CD105, NeuN, Oligo-2 in brain tissues were measured by immunohistochemistry staining and ANG-2, HMGB-1, and matrix metalloproteinase-9 (MMP-9) were detected by western blotting. Blood glucose levels of rats in diabetic model group were significantly elevated and blood glucose levels of rats in liraglutide treatment group were reduced to comparable levels with control group. PAS staining showed vascular basement membrane of rats in the diabetic model group was thicker than that of the control group. ANG-2, HMGB1 and MMP-9 were up-regulated in the diabetic model group comparing the control group, while down-regulated after treated with liraglutide (p<0.05). NeuN expressions were significantly higher in liraglutide treatment group. Liraglutide may have protective roles against brain injury of streptozotocin induced diabetic rats by inhibiting HMGB1, which further suppressing the MMP-9 and ANG-2.

Abstract
Abstract
Introduction/Objective
Sweat gland carcinomas are a group of malignant skin adnexal tumors that are difficult to diagnose due to their rarity, wide morphologic variation, and limited literature on diagnosis and classification. These tumors may appear bland and morphologically resemble benign skin adnexal tumors, or may appear poorly differentiated and mimic metastatic carcinoma especially from a breast primary. Biphasic sweat gland carcinomas are an even rarer entity, with only few cases reported in literature, and have been described to consist of a well- differentiated ductal epithelial component and a poorly differentiated, sarcomatoid, spindle cell component.
Methods/Case Report
Our case report describes a 53 year old female referred to our institution for diagnosis of an excised skin lesion of the right upper arm, which had been slowly growing for 8 years. The histology revealed a biphasic malignant neoplasm involving the dermis and subcutis. The tumor consisted of an epithelial cell component with glandular and squamoid morphology and positive for CK5/6, CK7, and CAM5.2, and a spindled myoepithelial cell component with sarcomatoid morphology and positive for S100, vimentin, and p63. Stains for CK20, ER, PR, PAX8, CEA, and TTF1 were negative. The histological and clinical findings favored a primary skin adnexal tumor, rather than a metastatic lesion.
The patient underwent wide local excision of the lesion given that margins of the original excision were indeterminate. The histology of this re-excision demonstrated the same biphasic tumor with ductal epithelial and sarcomatoid myoepithelial cell components positive for the same stains. Although margins were negative in this re-excision, 3-4 months later, the patient developed dyspnea with multiple new pulmonary and hilar masses discovered on imaging, and new-onset headache with a frontal lobe mass discovered on brain imaging. These masses were biopsied/resected, and revealed to be metastases of the original cutaneous tumor positive for the same markers.

NA
Conclusion
This case report describes a rare, diagnostically challenging case of a biphasic sweat gland carcinoma with ductal epithelial and sarcomatoid myoepithelial cell components, which demonstrated aggressive behavior with distant metastasis. These tumors are a clinicopathological quandary given their rarity and the paucity of literature on their characterization.

Abstract
The versatile properties make hydrogels a potential multipurpose material that finds wide applications. However, the preparation of multipurpose hydrogels is very challenging. Here, we report a method based on free radical reaction and composite mechanisms to prepare mechanical and electrical self-healing multifunctional hydrogels. In this study, the introduction of imidazolium salt ionic liquids and glycerol in the hydrogel system endows the gels with good antibacterial, conductive, and adhesive properties and excellent antifreeze properties. The testing results show that the as-prepared hydrogel has stable mechanical and electrical properties even under the extremely cold condition of -50°C after self-healing. Moreover, the active esters formed in the dynamic radical reaction have better reducibility, thus further investing the as-prepared hydrogel with high antioxidant activity. The application results show that these comprehensive properties make such hydrogel system very useful in wound repair and wearable strain sensors.
