Abstract
Xanthine oxidoreductase (XOR) and uric acid transporter 1 (URAT1) are two most widely studied targets involved in production and reabsorption of uric acid, respectively. Marketed drugs almost target XOR or URAT1, but sometimes, single agents might not achieve aim of lowering uric acid to ideal value in clinic. Thus, therapeutic strategies of combining XOR inhibitors with uricosuric drugs were proposed and implemented. Based on our initial work of virtual screening, A and B were potential hits for dual-targeted inhibitors on XOR/URAT1. By docking A/B with XOR/URAT1 respectively, compounds I1-7 were designed to get different degree of inhibition effect on XOR and URAT1, and I7 showed the best inhibitory effect on XOR (IC50 = 0.037 ± 0.001 μM) and URAT1 (IC50 = 546.70 ± 32.60 μM). Further docking research on I7 with XOR/URAT1 led to the design of compounds II with the significantly improved inhibitory activity on XOR and URAT1, such as II11 and II15. Especially, for II15, the IC50 of XOR is 0.006 ± 0.000 μM, superior to that of febuxostat (IC50 = 0.008 ± 0.000 μM), IC50 of URAT1 is 12.90 ± 2.30 μM, superior to that of benzbromarone (IC50 = 27.04 ± 2.55 μM). In acute hyperuricemia mouse model, II15 showed significant uric acid lowering effect. The results suggest that II15 had good inhibitory effect on XOR/URAT1, with the possibility for further investigation in in-vivo models of hyperuricemia.

Abstract
Objective: To analyze the drug-resistant gene loci of Mycoplasma pneumoniae (MP) using metagenomic next-generation sequencing (mNGS). Methods: From November 2022 to October 2023, 697 clinical samples (including sputum, alveolar lavage fluid and blood) of 686 children with Mycoplasma pneumoniae positive detected by mNGS were retrospectively analyzed. Samples were divided into intensive care unit (ICU) group and non-ICU group, Chi-square test was used to compare groups, and Mann-Kendall trend test was used to analyze the change trend of the detection rate of drug resistance gene loci over time. Results: Of the 697 samples, 164 were from the ICU group and 533 were from the non-ICU group. The detection rate of Mycoplasma pneumoniae resistance gene was 44.3% (309/697), and all detected drug-resistant gene loci of MP were A2063G. The detection rate of Mycoplasma pneumoniae in ICU group was 50.0% (82/164), and the detection rates of Mycoplasma pneumoniae resistance gene loci in sputum, alveolus lavage fluid and blood samples were 75.0% (18/24) and 48.4% (62/128), respectively. The detection rate in sputum was higher than alveolus lavage fluid samples (χ2=5.72,P=0.017). The detection rate of Mycoplasma pneumoniae in non-ICU group was 42.6% (227/533), the detection rate of Mycoplasma pneumoniae resistance gene loci in sputum and alveolar lavage fluid was 40.0% (16/40), 44.3% (201/454), and no detection rate in blood samples (0/12). There was no significant difference in the detection rate of alveolar lavage fluid and sputum (χ2=0.27, P=0.602). From November 2022 to October 2023, the detection rate of submitted samples showed an increasing trend month by month (overall: Z=3.99, ICU inspection group: Z=2.93, non-ICU group: Z=3.01, all P<0.01). Among the bacteria commonly detected with Mycoplasma pneumoniae, Streptococcus pneumoniae accounted for the highest proportion, the detection rate was 15.5% (108/697), and Epstein-Barr virus accounted for the highest proportion of 17.6% (123/697). Conclusions: From November 2022 to October 2023, the detection rate of Mycoplasma pneumoniae drug resistance gene loci showed an increasing trend. The detection rate of drug resistance gene loci in sputum samples of ICU group was higher than alveolus lavage fluid. No new drug resistance site were detected.

Abstract
AIM To compare the efficacy of quantitative contrast-enhanced ultrasonography (CEUS) analysis and colour Doppler ultrasound (CDU) in evaluating central retinal artery (CRA) microcirculation in patients with diabetes mellitus (DM). MATERIALS AND METHODS In this prospective study, a total of 55 patients (98 eyes) with DM were enrolled as the study group. They were compared to 46 age-matched healthy volunteers (92 eyes) who were selected as the control group. Each patient underwent CDU and subsequent CEUS examination. CDU and quantitative CEUS parameters were evaluated. The diagnostic efficiency of the diagnostic performance of CEUS and CDU was evaluated and compared, and the scale thresholds of predictive indicators for the diagnosis of proliferative diabetic retinopathy (PDR) were evaluated using receiver operating characteristics (ROC) curve analyses. RESULTS Group pairwise comparisons showed that the end diastolic velocity (EDV) and arrival time (AT) of CRA were significant predictors for PDR by CDU and by quantitative CEUS analysis, respectively (all p<0.05). The ROC curve analysis showed that the area under the curve value of AT was significantly higher than that of EDV (0.875 versus 0.634, p=0.0002). Accordingly, an AT cut-off value of 1.07 seconds resulted a sensitivity of 90.62 % and a specificity of 79.31 %. CONCLUSION Quantitative CEUS analysis can improve the accuracy of clinical staging of diabetic retinopathy for the patients with DM, and the AT showed the best diagnostic efficiency.

Abstract
Two-dimensional moiré materials have emerged as the most versatile platform for realizing quantum phases of electrons. Here, we explore the stability origins of correlated states in WSe_{2}/WS_{2} moiré superlattices. We find that ultrafast electronic excitation leads to partial melting of the Mott states on timescales 5 times longer than predictions from the charge hopping integrals and that the melting rates are thermally activated, with activation energies of 18±3 and 13±2 meV for the one- and two-hole Mott states, respectively, suggesting significant electron-phonon coupling. A density functional theory calculation of the one-hole Mott state confirms polaron formation and yields a hole-polaron binding energy of 16 meV. These findings reveal a close interplay of electron-electron and electron-phonon interactions in stabilizing the polaronic Mott insulators at transition metal dichalcogenide moiré interfaces.

Abstract
BACKGROUND Hashimoto thyroiditis (HT) is a common autoimmune thyroid disease for which there is no specific treatment. Oral levothyroxine sodium tablets significantly improved thyroid function but did not promote a reduction in thyroid-related antibody concentrations. Acupuncture can improve clinical symptoms and thyroid function in HT patients, reduce serum TPOAb and TGAb levels in HT patients, and improve patients' quality of life. METHODS We conducted a systematic review and meta-analysis to evaluate the effect of acupuncture versus levothyroxine sodium tablets on Hashimoto thyroiditis. We searched Web of Science, Embase, China National Knowledge Infrastructure, WanFang, VIP, SinoMed and the Cochrane Central Registry of Controlled Trials to identify candidate randomized controlled trials (RCTs). RESULTS A total of 1020 patients participated in 14 randomized controlled trials. The results of meta-analysis showed that acupuncture regulated TPOAb content (mean difference [MD] = -63.18, 95%CI = -91.73 to -34.62, P < .00001), TGAb content (MD = -68.56, 95%CI = -101.55 to -35.57, P < .00001), serum free triiodothyronine (FT3) content (MD = 0.74, 95%CI = 0.20 to 1.27, P < .00001), serum free thyroxine (FT4) content (MD = 1.10, 95%CI = 0.29 to 1.92, P < .00001), TSH content (MD = -2.16, 95%CI = -3.14 to -1.19, P < .00001) had a significant effect. CONCLUSION Compared with levothyroxine sodium tablets alone, acupuncture can significantly regulate the contents of TPOAb, TGAb, FT3, FT4 and TSH.

Abstract
Objective: To evaluated the clinical efficacy of a reduced-intensity preconditioning regimen for single non-blood-related umbilical cord blood transplantation (sUCBT) in the treatment of severe aplastic anemia (SAA) . Methods: The clinical data of 63 patients with SAA who underwent sUCBT from January 2021 to July 2023 at the Department of Hematology of the First Affiliated Hospital of USTC were retrospectively analyzed. Fifty-two patients received total body irradiation/total bone marrow irradiation (TMI) combined with fludarabine or a cyclophosphamide- conditioning regimen (non-rATG group) , while 11 patients received rabbit anti-human thymocyte immunoglobulin (rATG) combined with TMI, fludarabine, or the cyclophosphamide-conditioning regimen (rATG group) . All patients received cyclosporine A and mycophenolate mofetil for graft-versus-host disease (GVHD) prophylaxis. Complications post-transplantation and long-term survival were compared between the two groups. Results: The baseline parameters were balanced between the two groups (P>0.05) . In the rATG group, all patients achieved stem cell engraftment, and in the non-rATG group, five patients had primary graft failure. There was no significant difference in the cumulative incidence of neutrophil engraftment at 42 days after transplantation or platelet engraftment at 60 days between the two groups. The incidence of grade Ⅱ-Ⅳ acute GVHD in the rATG group was significantly lower than in the non-rATG group (10.0% vs. 46.2% , P=0.032) , and the differences in the cumulative incidences of grade Ⅲ/Ⅳ acute GVHD and 1-year chronic GVHD were not statistically significant (P=0.367 and P=0.053, respectively) . There were no significant differences in the incidences of pre-engraftment syndrome, bacterial bloodstream infections, cytomegalovirus viremia, or hemorrhagic cystitis between the two groups (P>0.05 for all) . The median follow-up time for surviving patients was 536 (61-993) days, and the 1-year transplantation related mortality (TRM) of all patients after transplantation was 13.0% (95% CI 6.7% -24.3% ) . Among the patients in the non-rATG and rATG groups, 15.5% (95% CI 8.1% -28.6% ) and 0% (P=0.189) , respectively, had mutations. The 1-year overall survival (OS) rate of all patients after transplantation was 87.0% (95% CI 75.7% -93.3% ) . The 1-year OS rates in the rATG group and non-rATG group after transplantation were 100% and 84.5% , respectively (95% CI 71.4% -91.9% ) (P=0.198) . Conclusion: The preliminary results of sUCBT with a low-dose irradiation-based reduced-intensity conditioning regimen with fludarabine/cyclophosphamide for the treatment of patients with SAA showed good efficacy. Early application of low-dose rATG can reduce the incidence of acute GVHD after transplantation without increasing the risk of implantation failure or infection.

Abstract
To evaluate the effectiveness of perioperative nursing intervention in patients undergoing ureteroscopic lithotripsy (URSL) for ureteral stones and its implications for the incidence of adverse events, a total of 144 patients with ureteral stones admitted to our hospital from January 2021 to December 2022 were selected for retrospective analysis. They were divided into 2 groups based on their different nursing methods, with 72 patients in each group. The control group (CG) received routine nursing intervention, while the study group (SD) received refined perioperative nursing intervention. The surgical situation, effective stone removal rate, postoperative pain, inflammatory factors, stress response, and incidence of adverse events were compared between the 2 groups. In comparison with the CG, the SD demonstrated a significant reduction in gastrointestinal recovery time, urinary catheter removal time, and hospitalization duration, all presenting statistically significant disparities (P < .05). Notably, the SD exhibited a one-time stone removal rate significantly superior to that of the CG (P < .05). Similarly, the postoperative pain index was significantly lower in the SD (P < .05). Pre- and post-surgical serotonin (5-HT) levels in the SD were markedly lower than in the CG (P < .05). Postoperative levels of Interleukin-10 (IL-10), C-reactive protein (CRP), and white blood cells (WBC) were elevated in both groups, and gradually declined as the patients recovered. However, postoperative levels of IL-10, CRP, and WBC were significantly lower in the SD (P < .05). The SD also showed significantly lower levels of malondialdehyde and higher levels of superoxide dismutase (P < .05). Postoperative levels of cortisol, adrenocorticotropic hormone, and norepinephrine were elevated and progressively returned to normal over time, and were significantly lower in the study group (P < .05). Furthermore, the SD experienced a significant reduction in adverse event incidence compared with the CG (P < .05). Implementing refined perioperative nursing interventions for patients undergoing URSL can effectively decrease the incidence of adverse events, diminish the surgical stimulation of inflammation markers and oxidative stress indicators, and foster patient recovery.

Abstract
Thirteen new Euphorbia diterpenoids, euphylonanes A-M (1-13), and eight known ones were isolated from the whole plants of Euphorbia hylonoma. Compounds 1 and 2 are two rearranged ingenanes bearing a rare 6/6/7/3-fused ring system. Compound 3 represents the first example of a 9,10-epoxy tigliane, while 4-21 are typical ingenanes varying with substituents. Structures were elucidated using a combination of spectroscopic, computational, and chemical methods. Most ingenanes exerted a significant antiadipogenic effect in 3T3-L1 adipocytes, among which 4 was the most active with an EC50 value of 0.60 ± 0.27 μM. Mechanistic study revealed that 4 inhibited the adipogenesis and lipogenesis in adipocytes via activation of the AMPK signaling pathway.

Abstract
Nuclear transporter importin-β1 is emerging as an attractive target by virtue of its prevalence in many cancers. However, the lack of druggable inhibitors restricts its therapeutic proof of concept. In the present work, we optimized a natural importin-β1 inhibitor DD1 to afford an improved analog DD1-Br with better tolerability (>25 folds) and oral bioavailability. DD1-Br inhibited the survival of castration-resistant prostate cancer (CRPC) cells with sub-nanomolar potency and completely prevented tumor growth in resistant CRPC models both in monotherapy (0.5 mg/kg) and in enzalutamide-combination therapy. Mechanistic study revealed that by targeting importin-β1, DD1-Br markedly inhibited the nuclear accumulation of multiple CRPC drivers, particularly AR-V7, a main contributor to enzalutamide resistance, leading to the integral suppression of downstream oncogenic signaling. This study provides a promising lead for CRPC and demonstrates the potential of overcoming drug resistance in advanced CRPC via targeting importin-β1.

Abstract
Objective: To analyze the report content, the methods and results of prenatal diagnosis of high risk of sex chromosome aneuploidy (SCA) in non-invasive prenatal testing (NIPT). Methods: A total of 227 single pregnancy pregnant women who received genetic counseling and invasive prenatal diagnosis at Drum Tower Hospital Affiliated to the Medical School of Nanjing University from January 2015 to April 2022 due to the high risk of SCA suggested by NIPT were collected. The methods and results of prenatal diagnosis were retrospectively analyzed, and the results of chromosome karyotype analysis and chromosome microarray analysis (CMA) were compared. The relationship between NIPT screening and invasive prenatal diagnosis was analyzed. Results: (1) Prenatal diagnosis methods for 277 SCA high risk pregnant women included 73 cases of karyotyping, 41 cases of CMA and 163 cases of karyotyping combined with CMA, of which one case conducted amniocentesis secondly for further fluorescence in situ hybridization (FISH) testing. Results of invasive prenatal diagnosis were normal in 166 cases (59.9%, 166/277), and the abnormal results including one case of 45,X (0.4%, 1/277), 18 cases of 47,XXX (6.5%, 18/277), 36 cases of 47,XXY (13.0%, 36/277), 20 cases of 47,XYY (7.2%, 20/277), 1 case of 48,XXXX (0.4%, 1/277), 20 cases of mosaic SCA (7.2%, 20/277), 5 cases of sex chromosome structural abnormality or large segment abnormality (1.8%, 5/277), and 10 cases of other abnormalities [3.6%, 10/277; including 9 cases of copy number variation (CNV) and 1 case of balanced translocation]. Positive predictive value (PPV) for SCA screening by NIPT was 34.7% (96/277). (2) Among the 163 cases tested by karyotyping combined with CMA, 11 cases (6.7%, 11/163) showed inconsistent results by both methods, including 5 cases of mosaic SCA, 1 case of additional balanced translocation detected by karyotyping and 5 cases of additional CNV detected by CMA. (3) NIPT screening reports included 149 cases of "sex chromosome aneuploidy"(53.8%, 149/277), 54 cases of "number of sex chromosome increased" (19.5%, 54/277), and 74 cases of "number of sex chromosome or X chromosome decreased" (26.7%, 74/277). The PPV of "number of sex chromosome increased" and "number of sex chromosome or X chromosome decreased" were 72.2% (39/54) and 18.9% (14/74), respectively, and the difference was statistically significant (χ2=34.56, P<0.01). Conclusions: NIPT could be served as an important prenatal screening technique of SCA, especially for trisomy and mosaicism, but the PPV is comparatively low. More information of NIPT such as the specific SCA or maternal SCA might help improving the confidence of genetic counseling and thus guide clinic management. Multi technology platforms including karyotyping, CMA and FISH could be considered in the diagnosis of high risk of SCA by NIPT.

Abstract
Objective: To explore the influencing factors of AIDS-related deaths among HIV-infected patients in Shandong Province, to help reduce the risk of death and prolong survival time. Methods: The study population was HIV-infected patients in Shandong Province from 2017-2021, and Cox proportional hazards regression model was used to analyze the influencing factors of AIDS-related deaths and deaths within one year of confirmation. Results: Among 14 700 HIV- infected patients reported in Shandong Province in 2017-2021, 351 AIDS-related deaths occurred, accounting for 2.4% (351/14 700). The results of multifactorial Cox proportional hazards regression model analysis showed that the risk factors for AIDS-related deaths among HIV-infected patients included education level of junior high school, high school, and secondary school (aHR=1.37, 95%CI:1.01-1.84), sample source from healthcare institutions (aHR=1.61, 95%CI:1.22-2.12), duration of disease in AIDS stage (aHR=9.86,95%CI:6.86-14.19), baseline CD4+T lymphocytes (CD4) undetected (aHR=3.93, 95%CI:2.69-5.75), duration of antiviral treatment (ART) <6 months (aHR=3.46, 95%CI:2.42-4.93) and no ART (aHR=1.45, 95%CI:1.02-2.07), final CD4 <200 cells/μl (aHR=3.51, 95%CI:2.18-5.65) and final CD4 undetected (aHR=10.58, 95%CI:6.15-18.19), and final viral load (VL) values of 50-999 copies/ml,≥1 000 copies/ml and undetected (aHR=2.59, 95%CI:1.07-6.26; aHR=9.50, 95%CI:5.60-16.12; aHR=15.33, 95%CI:8.91-26.36). Factors with higher risk of AIDS-related deaths within one year of confirmation of HIV-infected patients included samples originating from healthcare facilities (aHR=1.68, 95%CI: 1.19-2.36), AIDS stage of disease (aHR=10.60, 95%CI:7.13-15.75), baseline CD4 undetected (aHR=3.71, 95%CI:2.34-5.90), duration of ART <6 months (aHR=4.30, 95%CI:2.85-6.49) and no ART (aHR=2.05, 95%CI:1.35-3.13), final CD4 <200 cells/μl (aHR=5.45,95%CI:2.04-14.60) and final CD4 undetected (aHR=20.95, 95%CI: 7.69- 57.04), and final VL values of 50-999 copies/ml, ≥1 000 copies/ml and undetected (aHR=15.21, 95%CI: 2.54-91.21; aHR=42.93, 95%CI:9.64-191.20; aHR=61.35, 95%CI:13.85-271.77). Conclusions: Expanding the coverage of testing, promoting early detection and treatment, strengthening regular follow-up and the test of HIV-infected patients, grasping the progress of the disease to provide accurate management and treatment are important for reducing the disease mortality rate and prolonging the survival time of HIV-infected patients.

Abstract
Objective This study aimed to investigate the effectiveness of enhanced recovery after surgery (ERAS) during the perioperative period for patients with ureteral stones. Methods A total of 105 patients with ureteral stones who underwent holmium laser lithotripsy at our hospital between January 2020 and January 2021 were included in the study. They were randomly divided into two groups using a random number table: the research group (n = 53) received ERAS, while the control group (n = 52) received conventional care. Postoperative recovery parameters were compared between the two groups, including time to mobilization, time to void, time to rehydration, time to remove the urinary catheter, and length of hospital stay. Visual analogue scoring (VAS) scores were assessed at 12, 24, 36, and 48 hours postoperatively. The General Quality of Life Questionnaire (GQOLI-74) scores and complication rates were compared. Results The research group exhibited significantly shorter postoperative time to mobilization, time to void, time to rehydration, time to remove the urinary catheter, and length of hospital stay compared to the control group (P < .05). VAS scores at 12, 24, 36, and 48 hours postoperatively were significantly lower in the research group than in the control group (P < .05). Furthermore, post-intervention, all GQOLI-74 scores were significantly higher in the research group than in the control group (P < .05). The complication rate in the research group was 5.66% lower than in the control group (25.00% vs. 30.66%, respectively, P < .05). Conclusions The application of ERAS during the perioperative period for patients with ureteral stones is associated with improved postoperative recovery, reduced postoperative pain, lower complication rates, and enhanced quality of life. These findings suggest that ERAS is a valuable approach to be promoted for clinical use.

Abstract
BACKGROUND There is still a therapeutic challenge in treating gastric cancer (GC) due to its high incidence and poor prognosis. Collagen type V alpha 2 (COL5A2) is increased in various cancers, yet it remains unclear how it contributes to the prognosis and immunity of GC. METHODS The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets were used to download transcriptome profiling (TCGA-STAD; GSE84437), single-cell RNA sequencing (scRNA-seq) data (GSE167297) and clinical information. COL5A2 expression and its relationship with clinicopathological factors were analyzed. We conducted survival analysis and Cox regression analysis to evaluate the prognosis and independent factors of GC. Co-expressed analysis was also performed. To identify the underlying mechanism, we conducted analyses of differentially expressed genes (DEGs) and functional enrichment. The correlations between COL5A2 expression and immune cell infiltration levels and immune infiltrate gene marker sets were further explored. Additionally, we analyzed the association of COL5A2 expression with immunological checkpoint molecules. Furthermore, the relationship between COL5A2 expression and immunotherapy sensitivity was also investigated. RESULTS COL5A2 expression was elevated in GC. More than this, the scRNA-seq analysis revealed that COL5A2 expression had a spatial gradient. The upregulated COL5A2 was associated with worse overall survival. A significant correlation was found between COL5A2 overexpression and age, T classification and clinical stage in GC. COL5A2 was found to be an independent factor for the unfortunate outcome in Cox regression analysis. The co-expressed genes of COL5A2 were associated with tumor stage or poor survival. Enrichment analysis revealed that the DEGs were mainly associated with extracellular matrix (ECM)-related processes, PI3K-AKT signaling pathway, and focal adhesion. GSEA analyses revealed that COL5A2 was associated with tumor progression-related pathways. Meanwhile, COL5A2 expression was correlated with tumor-infiltrating immune cells. Moreover, immunophenoscore (IPS) analysis and PRJEB25780 cohorts showed that patients with low COL5A2 expression were highly sensitive to immunotherapy. CONCLUSIONS COL5A2 might act as a prognostic biomarker of GC prognosis and immune infiltration and may provide a therapeutic intervention strategy.

Abstract
This study explored the potential role of long noncoding RNA (lncRNAs) associated with genomic instability in the diagnosis and treatment of pancreatic adenocarcinoma (PAAD). Transcriptome and single-nucleotide variation data of PAAD samples were downloaded from the cancer genome atlas database to explore genomic instability-associated lncRNAs. We constructed a genomic instability-associated lncRNA prognostic signature. Then gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses were used to explore the physiological role of lncRNAs involved in genomic instability. Tumor microenvironments, immunotherapy response, immune cell infiltration, immune checkpoint, and drug sensitivity were compared between high-risk and low-risk groups. In vitro experiments were performed for external validation. Six lncRNAs associated with genomic instability were identified, capable of predicting the prognosis of PAAD. Patients were assigned to low-risk or high-risk groups using these biomarkers, with better or worse prognosis, respectively. The tumor immune score, immune cell infiltration, and efficacy of immunotherapy were worse in the high-risk group. A drug sensitivity analysis revealed the high- and low-risk groups had different half-maximal inhibitory concentrations. The expression of cancer susceptibility candidate 8 was significantly higher in tumor tissues than in normal tissues, while the expression of LYPLAL1-AS1 exhibited an opposite pattern. They may be potential diagnostic or prognostic biomarkers for patients with pancreatic cancer. Genomic instability-associated lncRNAs were explored in this study and predicted the prognosis of PAAD and stratified patients risk in PAAD. These lncRNAs also predicted the efficacy of immunotherapy and potential therapeutic targets in PAAD.

Abstract
Objective: To compare the characteristics of MSM with different types of primary sexual partners and to analyze the factors associated with MSM not being tested for HIV in the last six months. Methods: MSM were recruited in nine cities of Shandong Province from April to July 2021, and face-to-face questionnaires were conducted to collect information on sociodemographic characteristics, high-risk behaviors, and HIV testing of MSM. Blood samples were taken for serological tests of HIV and syphilis antibodies. Results: A total of 3 008 men who had anal sex with men in the last six months were divided into three groups according to the type of primary sexual partner in the last six months: the fixed sexual partner group (36.83%, 1 108/3 008), the commercial sexual partner group (3.06%, 92/3 008), and casual sexual partner group (60.11%, 1 808/3 008). There were statistically significant differences in the distribution of age, local residence time, education level, the primary place to find male sexual partners, use of new-type drugs in the last six months, consistent condom use every time during same-sex anal sex in the last six months, group sex in the last six months, no HIV testing in the last six months, having had a sexually transmitted disease in the last year, receiving peer education in the last year, and frequency of syphilis testing in the last year among different groups (P<0.05). Multivariable logistic regression analysis showed that related factors of not being tested for HIV in the last six months in MSM were those aged less than 30 years old (aOR=1.39, 95%CI: 1.06-1.83), married/cohabiting (aOR=1.74, 95%CI: 1.39-2.16), high school education or less (aOR=1.39, 95%CI: 1.15-1.67), had not used new-type drugs in the last six months (aOR=2.27, 95%CI: 1.89-2.71), had not received peer education in the last year (aOR=1.59, 95%CI: 1.28-1.98), had never been tested for syphilis (aOR=11.30, 95%CI: 8.15-15.66), had not been tested in the last year but had been previously tested for syphilis (aOR=5.65, 95%CI: 4.19-7.62), the type of primary sexual partner in the last six months being a commercial sexual partner (aOR=1.80, 95%CI: 1.01-3.20), and the type of primary sexual partner in the last six months being a casual sexual partner (aOR=1.50, 95%CI: 1.26-1.80). Conclusions: The characteristics of MSM with different types of primary sexual partners are different, and the proportion of HIV testing still needs to be improved. In the future, we should make full use of the Internet and peer education to expand the coverage of HIV testing for MSM, targeting the characteristics of MSM with different types of primary sexual partners.

Abstract
This study aimed to investigate the potential therapeutic effects of nicotinamide phosphoribosyltransferase (NAMPT)-mediated adenine dinucleotide (NAD) biosynthesis in depression models in vivo. Namptflox/flox mice were used to evaluate the role of NAMPT in depression. NAMPT and NAD levels in the prefrontal cortex (PFC) were measured, and depression-associated behavior, cognitive function, and social interaction were evaluated. The expression levels of BDNF, pCREB, CREB, monoamine neurotransmitters, and corticosterone (CORT) were also detected in the PFC. The contents of NAMPT and NAD decreased in the PFC in Namptflox/flox mice. Namptflox/flox mice showed depression-like behaviors, cognitive function deterioration, decreased social ability, and decreased dominance. Meanwhile, there were decreased expression levels of the pCREB/CREB ratio, but not BDNF, in the PFC. Levels of DA, 5-HT, and NE were decreased, and CORT was activated in the PFC of Namptflox/flox mice. Additionally, the role of NAMPT-NAD was examined in rats treated with nicotinamide riboside (NR) after being exposed to chronic unexpected mild stress (CUMS). NR reversed the decreased NAMPT expression in the PFC and HIP, and the NAD content in the PFC, but not HIP in rats with CUMS-induced depression. NR also improved depressive- and anxiolytic-like behaviors, locomotor activity, and cognitive function. BDNF expression and the pCREB/CREB ratio were significantly increased in both the PFC and HIP after NR treatment. The activation of CORT and decreased content of DA were reversed after NR treatment in the PFC. There was no difference in the 5-HT content among groups in both the PFC and HIP. Taken together, NAD synthesis induced by NAMPT could be associated with depression-like behaviors in mice, and the elevated NAD level by NR improved depression in rats.

Abstract
CONTEXT The alkaloids of Narcissus tazetta L. var. Chinensis Roem (Amaryllidaceae) have antitumor and antiviral activities. However, the immunopharmacological effects of one of its constituents, pseudolycorine chloride (PLY), have not been reported yet. OBJECTIVE We evaluated the effect of PLY on myeloid-derived suppressor cells (MDSCs) expansion and differentiation into monocyte-like MDSCs (M-MDSCs) and examined whether PLY alleviates Th17 cell-mediated experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS). MATERIALS AND METHODS In vitro, MDSCs were treated with PLY (0.67, 2 and 6 μM) or solcitinib (10 μM, positive control) for 48 or 96 h, and their proliferation, expansion, and differentiation into M-MDSCs were examined by flow cytometry. Myelin oligodendrocyte glycoprotein (MOG35-55) was used to induce EAE in female C57BL/6 mice, and the mice were treated with 40 mg/kg/d PLY or 1 mg/kg/d FK-506 (tacrolimus, positive control) for 21 days. Inflammatory infiltration, spinal cord demyelination, and MDSCs and Th17 cells infiltration into the spinal cord were examined using haematoxylin and eosin staining, Luxol fast blue staining, and immunofluorescence, respectively. RESULTS In vitro, PLY (IC50/24 h = 6.18 μM) significantly inhibited IL-6 and GM-CSF-induced MDSCs proliferation, expansion and differentiation into M-MDSCs at all concentrations used. However, these concentrations did not show cytotoxicity. In mice, PLY (40 mg/kg) treatment alleviated EAE and inhibited inflammatory infiltration, demyelination, and MDSCs and Th17 cells infiltration into the spinal cord. DISCUSSION AND CONCLUSIONS PLY may be an excellent candidate for the treatment of MS and other autoimmune diseases.

Abstract
Objective: To understand the characteristics and depressive status of men who have sex with men (MSM) who self-reported HIV infection through heterosexual transmission and to provide evidence for personalized management of HIV infected people. Methods: A cross-sectional survey was carried out in Shandong province from September to December in 2019. Male HIV patients aged ≥15 years who self-reported HIV infection through heterosexual transmission were selected to verify the route of infection by one-to-one interview in Ji'nan, Qingdao, Weifang and Linyi cities of Shangdong province. According to the 1∶1 ratio, local HIV patients with age difference ≤3 years who self-reported MSM were selected as controls. A questionnaire survey was conducted, including data on demographic characteristics, behavior status, CES-D and PSSS. The related factors of the depressive symptoms and characteristics were analyzed. Results: A total of 373 male HIV patients were interviewed, and 39.7%(148/373) were confirmed as MSM after reexamination. The interviewers were: aged (40.3±12.0) years old, 41.9% (62/148) married/cohabiting. 27.0% (40/148) had been tested before HIV diagnosis, 71.6% (106/148) had homosexual partners ≥2 and 55.4% (82/148) had depressive symptom. Multivariate analysis showed that the MSM without HIV testings before diagnosis, had homosexual partners ≥2 before diagnosis, had first homosexual behavior at the age >30 years old and with depressive symptoms were more likely to conceal the true infection route. The incidence of depression among MSM who self-reported HIV infection through heterosexual transmission was related to physical health status social support and occupational stability. Conclusions: Some male HIV persons self-reported as being heterosexually transmitted were really transmitted through homosexual behavior. There were high-risk behaviors such as multiple partners and intersex among this group, and with high incidence of depression. It is necessary to encourage the reexamination program during follow-up and target on psychological and behavioral interventions, continuously.

Abstract
Background Neuromuscular choristoma (NMC) is a rare peripheral nerve lesion that is composed of ectopic mature muscle fibers and nerve fascicles, typically involving major nerve roots or trunks, such as the cranial nerves, brachial plexus, and sciatic nerves. The onset of NMC frequently occurs in the first decade of life. Here, we present the first documented case of a case of esophageal NMC in an adult patient. Case presentation A 46-year-old male patient presented in 2018 with a submucosal tumor of the esophagus. Upon presentation, the tumor was approximately 10 mm in diameter, covered by normal mucosa, and located in the left posterior wall of the esophagus in a position that was 30 cm from the incisor. The tumor was discovered incidentally during gastroscopic examination. In March 2021, endoscopic re-examination revealed no significant changes in the tumor. Endoscopic ultrasound revealed an oval hypoechoic mass with a homogeneous internal echo that originated from the muscularis propria with a maximum cross section of 13 mm × 6 mm. Resection was performed under gastroscopy. The resection specimen was 12 mm × 5 mm in size and was a well-demarcated, elastic, hard, and tough with a gray section. Histologically, the specimen consisted of an abundance of smooth muscle fiber bundles intercalated among nerve fibers, but without malignancy. Immunohistochemical examinations revealed positivity for S-100 protein, caldesmon, NSE and desmin, but negativity for CD117, DOG-1, HMB45, and Melan A. There was also aberrant nuclear localization of beta-catenin. Collectively, these findings led to a diagnosis of esophageal NMC. Conclusions NMC is extremely rare, especially esophageal NMC, and is very challenging to accurately diagnose prior to resection. It is important that we can differentiate NMC from other types of tumors.

Abstract
Objective: To describe gastric cancer incidence in Suzhou cohort, explore the environmental risk factors of gastric cancer in Suzhou, and provide appropriate suggestions for gastric cancer prevention and control. Methods: The participants were from the Suzhou cohort of China Kadoorie Biobank. Baseline survey was conducted from 2004 to 2008, followed by long-term follow-up until December 31, 2013. After the exclusion of those who had been previously diagnosed with peptic ulcer and malignant tumor reported at baseline survey and gastric cancer within six months after enrollment, a total of 50,136 participants were included. Cox proportional risk models were used to identify risk factors of gastric cancer and their hazard ratios in Suzhou. The effect modifications of gender on the association between risk factors and gastric cancer were analyzed. Results: In the follow-up of 7.19 years (median), 374 gastric cancers cases occurred. The standardized incidence was 94.57 per 100 000 person-years. Multivariate Cox proportional risk model analysis found that age (10 years old as a age group, HR=2.20, 95%CI: 1.92-2.53, P<0.001), current smoking (HR=1.84, 95%CI: 1.10-3.07 P=0.020), consumption of preserved vegetables weekly (HR=2.28, 95%CI: 1.28-4.07, P=0.005) and daily (HR=2.05, 95%CI: 1.16-3.61, P=0.013) were risk factors for gastric cancer. Female (HR=0.44, 95%CI: 0.25-0.76, P=0.003) and refrigerator use (10 years as a limit, HR=0.85, 95%CI: 0.74-0.97, P=0.016) were protective factors for gastric cancer. Further analysis showed that there was heterogeneity between males and females in the association between refrigerator use years and the incidence of gastric cancer (P=0.009), and there was an interaction effect between gender and refrigerator use on the incidence of gastric cancer (P=0.010). Conclusions: The incidence of gastric cancer in Suzhou cohort was high. The risk factors of gastric cancer varied. There was a synergistic interaction effect between gender and refrigerator use years on the incidence of gastric cancer.

Abstract
This study aimed to investigate the relationship between interleukin (IL)-35 level and IL-35-producing regulatory T cells (iTr35 subset) in Mycobacterium tuberculosis (Mtb)-infected mice. After the mice were injected with Mtb strain H37R via tail vein, the bacterial burden, lung lesions, and the impact of immune suppression on the infected mice were respectively assessed. The results, when compared with the control mice, showed that the mRNA expression levels of the p35 and Epstein-Barr virus-induced gene 3 of IL-35 were significantly increased in the Mtb-infected mouse spleen at 4 or 8 weeks post-infection and their protein expression levels were concurrently increased in the lungs of the mice, especially in 8 week infected mice. In addition, the levels of serum IL-35 and the iTr35 subset in the spleen of mice were also increased in 4 or 8 weeks post-infection compared with the control mice. Importantly, the high bacterial burden and lung lesions and the low mouse weight were found at 8 week post-infection. Therefore, the mice infected with Mtb resulted in elevating IL-35 level and iTr35 subset and increasing bacterial burden and lung lesions. The findings from the study suggest IL-35 and iTr35 cells may exert an immune suppression role in chronic Mtb-infected mice.

Abstract
Hyperuricemia is a common disease caused by a disorder of purine metabolism, which often causes hyperlipidemia and other metabolic diseases. WN1703 was demonstrated to be an effective xanthine oxidoreductase (XOR) inhibitor in our previous study. Here, we evaluated the pharmacodynamic effect of WN1703 on rats suffering from chronic hyperuricemia accompanied by disorders of lipid metabolism. We discovered that WN1703 was an efficacious uric acid (UA)-lowering compound. Simultaneously, it had effect on relieving renal injury, regulating lipid metabolism by reducing levels of triglycerides and low-density lipoprotein-cholesterol, increasing levels of high-density lipoprotein-cholesterol, and improving renal and liver lesions. WN1703 also exhibited anti-inflammatory and antioxidant activity by alleviating the increasing trend of levels of tumor necrosis factor-α, interleukin-1β, monocyte chemoattractant protein-1, and malondialdehyde, and improving the activity of superoxide dismutase and glutathione peroxidase. WN1703 appeared to be more effective than febuxostat in inhibiting XOR and had higher antioxidant activity. In general, the pharmacologic action of WN1703 showed a clear dose–effect relationship. WN1703 showed similar effects on lowering UA and inhibiting XOR to febuxostat. WN1703 could alleviate glucose and lipids metabolism disorder. WN1703 could improve anti-inflammatory effects, and antioxidant effects. The pharmacologic action of WN1703 is dose-dependent.

Abstract
We report on systematic temperature- and magnetic field-dependent studies of the EuGa4binary compound, which crystallizes in a centrosymmetric tetragonal BaAl4-type structure with space groupI4/mmm. The electronic properties of EuGa4single crystals, with an antiferromagnetic (AFM) transition atTN∼ 16.4 K, were characterized via electrical resistivity and magnetization measurements. A giant nonsaturating magnetoresistance was observed at low temperatures, reaching∼7×104% at 2 K in a magnetic field of 9 T. In the AFM state, EuGa4undergoes a series of metamagnetic transitions in an applied magnetic field, clearly manifested in its field-dependent electrical resistivity. BelowTN, in the ∼4-7 T field range, we observe also a clear hump-like anomaly in the Hall resistivity which is part of the anomalous Hall resistivity. We attribute such a hump-like feature to the topological Hall effect, usually occurring in noncentrosymmetric materials known to host topological spin textures (as e.g., magnetic skyrmions). Therefore, the family of materials with a tetragonal BaAl4-type structure, to which EuGa4and EuAl4belong, seems to comprise suitable candidates on which one can study the interplay among correlated-electron phenomena (such as charge-density wave or exotic magnetism) with topological spin textures and topologically nontrivial bands.

Abstract
The potential therapeutic application of oligonucleotides (ONs) that selectively suppress target genes through antisense and RNA interference mechanisms has attracted great attention. The clinical applications of ONs have overcome multiple obstacles and become one of the most active areas for the development of novel therapeutics. To achieve efficient and specific cellular internalization, conjugation of a variety of functional groups to ONs has been the subject of intensive investigations over the past decade. Among them, a promising liver-targeted N-acetylgalactosamine (GalNAc) ligand has been evaluated in multiple preclinical and clinical trials for improving the cellular uptake and tissue specific delivery of ONs. GalNAc-based delivery relies on the fact that liver hepatocytes abundantly and specifically express the asialoglycoprotein receptor that binds and uptakes circulating glycoproteins via receptor-mediated endocytosis. In recent years, encouraging progress has been made in the field of GalNAc conjugates. This review aims to provide an overview of GalNAc-mediated liver-targeted delivery of small interfering RNA and antisense oligonucleotides, and the immense effort as well as recent advances in the development of GalNAc-conjugated agents are described.

Abstract
Vortioxetine (Vot) is an effective antidepressant with unique mechanisms exerting multi-target effects. However, severe side-effects such as nausea and vomiting are commonly experienced under conditions of long-term administration. Eight amino acid modified Vot derivatives were designed and prepared in this study. Similar or lower binding affinities of the modified compounds to the serotonin transporter (SERT) than Vot was observed in the 4-(4-(dimethylamino)-styrl)-N-methylpyridinium (ASP+) uptake assay on RBL-2H3 cells. Additionally, the majority of derivatives remained sufficiently stable in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF), indicating achievement of intestinal absorption in the modified form. Afterwards, all derived compounds exhibited slower hepatic clearance and a longer half-life, compared to the parent drug Vot. Notably, threonine-modified 3f exhibited significantly lower activity to SERT, serine-modified 3e showed the fastest degradation rate in rat plasma, with hydrolysis to an extent of 50% in 10 min, and better pharmacokinetic properties in rat, including Cmax, t1/2, and especially AUC0-t, which was ~3-fold higher relative to the parent compound. Although, no clear understanding of SARs has been obtained, modification of Vot with amino acids containing hydroxyl groups may be beneficial to reduce the gastrointestinal side effect of Vot or obtain better pharmacokinetic properties, providing some ideas for the further study in the future.

Abstract
A structurally defined konjac glucomannan oligosaccharide (KGMOS) with a relatively high molecular weight and narrow molecular weight distribution (molecular weight ranging from 3000 to 4000 Da, degree of polymerization (dp) 8-11) was prepared from native konjac glucomannan (KGM), and the beneficial effects and molecular mechanisms of KGMOS on colonic functions were investigated in C57BL/6 mice. The results are the first to reveal that KGMOS regulated intestinal microflora composition to facilitate the production of colonic butyrate. Elevated butyrate production further increased the acetylation of histone proteins H3 and H4 and thus enhanced the transcription of the major colonic mucin gene Muc2 and the secretion of mucin elements, which represents a new molecular mechanism of KGM oligosaccharide consumption. The findings indicate that KGM oligosaccharides with specific molecular sizes have highly desirable functional properties and potentially could improve gut health by promoting the barrier function of the colonic mucosa.

Abstract
Objective: To understand the relationship between new-type drug use and high risk behavior in men who have sex with men (MSM) in Shandong province. Methods: Cross-sectional surveys was conducted to collect the information about demographics, sexual and drug use behaviors of MSM and HIV-related services in MSM in three sentinel surveillance sites in Shandong from April to July in 2019. Blood samples were taken from the MSM for serological tests of HIV antibody and syphilis antibody. Results: A total of 1 203 MSM were included in this study. The average age of the MSM was 30.2±8.9 years. Among these MSM, 67.7% (815) were unmarried; 66.9% (805) had education level of college or above; 62.2% (721/1 160) had unprotected sex behaviors and 16.3% (189/1 160) had group sex behavior in the past six months and 54.2% (652/1 203) ever used new-type drugs. HIV infection and syphilis prevalence rates were 3.1% (37/1 203) and 4.7% (56/1 203), respectively. Multivariable logistic analysis indicated that MSM who had unprotected anal sex in the past six months were more likely to be from Qingdao (aOR=1.59, 95%CI:1.13-2.23), with education level of high school or below (aOR=1.61, 95%CI: 1.20-2.16), with male sex partners from bars/dance halls or other venues (aOR=1.69, 95%CI: 1.06-2.69), with HIV knowledge awareness score <6 (aOR=1.55, 95%CI: 1.01-2.37), with ≥2 sex partner in the past week (aOR=1.48, 95%CI: 1.12-1.95), to have group sex behaviors in the past six months (aOR=2.43, 95%CI:1.61-3.67) and to use new-type drugs (aOR=1.46, 95%CI: 1.11-1.91). MSM who had group sex were more likely to have following features: being from Qingdao (aOR=2.21, 95%CI: 1.45-3.38), non-Shandong residents (aOR=2.13, 95%CI: 1.28-3.55), HIV knowledge awareness score ≥6 (aOR=3.11, 95%CI: 1.55-6.25), ever having unprotected anal sex behaviors (aOR=2.60, 95%CI: 1.71-3.96) and ever having male commercial sex (aOR=3.38, 95%CI: 1.92-5.95) in the past six months, ever using new-type drugs (aOR=2.71, 95%CI: 1.82-4.04), and never having HIV testing in the past year (aOR=2.66, 95%CI: 1.59-4.43). Conclusion: New-type drug use is common in MSM in Shandong. The use of new-type drugs promotes unprotected sex and group sex in MSM. Surveillance and intervention measures targeting this population should be strengthened.

Abstract
Objective: To observe the effect of intermittent hypoxia on intestinal bacterial translocation and mesenteric lymph node (MLN) structure and explore its mechanism. Methods: Twenty-four adult male Wistar rats were randomly divided into an experimental group (HI group) and a control group (UC group), with 12 rats in each. During the experiment, both groups were fed under the same conditions, but the HI group received simulated sleep apnea with hypoxic treatment. On the last day of the 2nd and 4th week of the experiment, 20% urethane(0.7 ml/100g) was used for anesthesia, and MLNs and corresponding small intestinal tissues were aseptically collected.HE staining was used to observe the microscopic changes of the tissues. The lymph node tissue was sent for pathogenic culture. The levels of oxide dismutase (SOD), lipid peroxide (MDA) and reactive oxygen species (ROS) were measured for the extent of oxidative stress. Serum diamine oxidase (DAO) was measured to assess the extent of intestinal mucosal damage. Result: MLNs and their corresponding small intestines were damaged in the HI group as compared to the UC group. With the prolongation of intermittent hypoxic time, the number of germinal centers in MLNs was significantly reduced, with the volume reduced, cortical medullary fusion aggravated, and the area ratio increased. The intestinal tissue showed severe damage to the intestinal epithelium, increased permeability, mucosal edema, and changes of the crypts. At the 4th week, MLNs in the HI group grew Clostridium perfringens under anaerobic conditions, confirming intestinal bacterial translocation. The contents of ROS, SOD and MDA in MLNs of the HI group were significantly higher than those in the UC group (P<0.05). At the 2nd week and the 4th week, the contents of ROS, SOD and MDA were not significantly changed in the UC group(P>0.05). While the content of ROS and MDA in MLNs of the HI group at 4th week was significantly higher than that in the second week (P<0.05), but no change of SOD was observed (P>0.05). Serum DAO levels in the HI group were higher than those in the UC group at week 2 and week 4 (P<0.05), suggesting that the degree of intestinal mucosal injury in the HI group was more serious than that in the UC group. Conclusion: Hypoxic exposure aggravated the degree of oxidative stress in rats. With the prolongation of intermittent hypoxia, the intestinal mucosa of rats was seriously damaged. The intestinal flora shifted to damage the structure of mesenteric lymph nodes, and oxidative stress was further aggravated, which in turn affected the integrity of the intestinal autoimmune function.

Abstract
Since companion dogs have the same living environment as humans, they are a good animal model for the study of human diseases; this is especially true of canine spontaneous mammary tumours models. A better understanding of the natural history and molecular mechanisms of canine mammary tumour is of great significance in comparative medicine. Here, we collected canine mammary tumour cases and then assayed the clinical cases by pathological examination and classification by HE staining and IHC. miRNA-497 family members (miR-497, miR-16, miR-195 and miR-15) were positively correlated with the breast cancer marker genes p63 and PTEN. Modulation of the expression of miR-497 in the canine mammary tumour cell lines CMT1211 and CMT 7364 induced apoptosis and inhibited cell proliferation. Mechanistically, IRAK2 was shown to be a functional target of miR-497 that affects the characteristics of cancer cells by inhibiting the activity of the NF-κB pathway. Overall, our work reveals the miR-497/IRAK2/NF-κB axis as a vital mechanism of canine mammary tumour progression and suggests this axis as a target in breast cancer.

Abstract
Objective: To explore the differential protein expressions in papillary thyroid carcinoma (PTC) with or without Hashimoto's thyroiditis (HT). Methods: Tissue microarray was prepared and the protein expression levels of v-Raf murine sarcoma viral oncogene homolog B1 (BRAF), vascular endothelial growth factor (VEGF), cyclinD1, mesothelial cell (MC) , CD56 and Galectin3 in the PTC tissues with or without HT were detected by immunohistochemical staining. Results: The positive expression rates of BRAF protein in the PTC tissues with or without HT groups were 55.4% (36/65) and 63.6% (42/66), respectively, without significant difference (P=0.336). The positive expression rates of VEGF protein in the PTC tissues with or without HT groups were 25.7% (19/74) and 25.8%(17/66), respectively, without significant difference (P=0.991). The positive expression rates of cyclin D1 protein in the PTC tissues with or without HT groups were 93.4% (71/76) and 97.6% (80/82), without significant difference (P=0.206). The positive expression rates of MC protein in the PTC tissues with or without HT groups were 86.1% (62/72) and 83.5%(71/85), without significant difference (P=0.654). The positive expression rates of Galectin3 protein in the PTC tissues with or without HT groups were 98.7% (76/77) and 97.5% (78/80), without significant difference (P=0.583). The positive expression rates of CD56 in the PTC tissues and adjacent thyroid follicular epithelial cells were 27.4% (32/117) and 65.0% (76/117), respectively, and the difference was statistically significant (P=0.001). The positive expression rates of CD56 in PTC tissues with or without HT were 35.5% (24/68) and 16.5% (13/79), respectively, and the difference was statistically significant (P=0.009). Conclusions: There are no significant differences in the expressions of BRAF, VEGF, CyclinD1, MC and Galectin3 between the PTC tissues with or without HT. However, the significantly differential expression of CD56 between the two group suggests that CD56 may be related to the pathogenesis of PTC with HT. CD56 may be used as a potential molecular marker in PTC diagnosis.

Abstract
Objective: To describe the clinical features of anti-myelin oligodendrocyte glycoprotein (MOG) antibody-positive cortical encephalitis in children. Methods: Patients who were hospitalized in Beijing Children's Hospital from June 2018 to October 2019, with positive MOG antibodies and phenotype of cortical encephalitis were retrospectively analyzed. Cell-based assays (CBAs) were used to test MOG antibodies. Results: Five patients had the phenotype of cortical encephalitis during follow-up, with 3 females and 2 males. The age of onset ranged from 8 years to 12 years and 1 month. At the last follow-up, 3 cases exhibited a monophasic course and 2 cases were with relapse and remission courses. Six out of 8 episodes which had the phenotype of cortical encephalitis presented with seizures, among which 3 episodes had status epilepticus. None had recurrent seizures during remission. Other symptoms included fever (7/8), headache and vomiting (4/8), somnolence (3/8) and hemiplegia (1/8). Unilateral cortical swelling was observed in cerebral magnetic resonance imaging (MRI) of all patients, without any hemorrhage and necrosis. White blood cell (WBC) counts of cerebrospinal fluid increased, ranging from8×10(6)/L to 186×10(6)/L. All patients recovered well after treatment with intravenous immunogloblin and glucocorticoid. Two patients had relapses during follow-up and were additionally treated with mycophenolate mofetil. Conclusions: Anti-MOG antibodies can induce cortical encephalitis. In clinical setting, fever, headache and seizures are common, however, severe consciousness disturbance and local neurological deficits are rare in these patients. Cerebral MRI shows unilateral cortical swelling without any hemorrhage and necrosis. Usually, immunotherapy works well. No patients exist repeated seizures in remission, but some patients may have relapses.

Abstract
Stomach adenocarcinoma (STAD) is one of the most common malignancies. But the molecular mechanism is unknown. In this study, we downloaded the transcriptional profiles and clinical data of 344 STAD and 30 normal samples from The Cancer Genome Atlas (TCGA) database. Stromal and immune scores of STAD were calculated by the Estimation of Stromal and Immune cells in Malignant Tumor tissues using Expression data (ESTIMATE) algorithm, and association of stromal/immune scores with tumor differentiation/T/N/M stage and survival was investigated. The differentially expressed genes (DEGs) between high and low score groups (based on media) were identified, and prognostic genes over-/underexpressed in both STAD and stromal/immune signature were retrieved. Furthermore, proportions of 22 infiltrating immune cells for the cohort from TCGA were estimated by the Cell-type Identification By Estimating Relative Subsets Of RNA Transcripts (CIBERSORT) algorithm, and association of 22 immune cells with tumor differentiation/T/N/M stage and survival was investigated. Next, coexpression analysis of 22 immune cells and intersection genes over-/underexpressed in both STAD and stromal signature was conducted. We found high stromal and immune scores and macrophage infiltration predicting poor tumor differentiation and severe local invasion, obtained a list of prognostic genes based on stromal-immune signature, and explored the interaction of collagen, chemokines such as CXCL9, CXCL10, and CXCL11, and macrophage through coexpression analysis and may provide novel prognostic biomarkers and immunotherapeutic targets for STAD.

Abstract
Objective: To investigate the efficacy and safety of low-dose Ruxolitinib in the treatment of patients with chronic graft-versus-host disease (cGVHD) and refractory to the first-line and/or second-line drugs after allogeneic hematopoietic stem cell transplantation. Methods: The clinical data was retrospectively analyzed of patients diagnosed with cGVHD in Anhui Provincial Hospital from July 9, 2018 to May 23, 2019. They were refractory to first-line and second-line drugs and were given a low-dose of Ruxolitinib (a dose of 5 mg twice daily if body weight ≥ 25 kg and 2.5 mg twice daily if body weight<25 kg). There was 2.5 mg reduction per week or every two weeks if the condition improved until withdrawal. The efficacy and safety of Ruxolitinib were retrospectively analyzed weekly or biweekly. If the condition improved, the dosage would be reduced by 2.5 mg weekly or biweekly until discontinuance. Results: A total of 47 patients were included in the study,and the median time of taking Ruxolitinib was 55 (21-154) days. The median time of taking effect was 14(7-28) days. The overall response rate was 87.2% (41/47). The complete response rate was 63.8% (30/47) and the partial response rate was 23.4%(11/47). Among them, 13 cases were mild and the overall response rate was 100%(13/13). Twenty one cases were moderate and the overall response rate was 90.5%(19/21). Thirteen cases were severe and the overall response rate was 69.2%(9/13). The highest overall response rate of all organs the was 100% in the gastrointestinal tract (7/7), and it was 95.8%(23/24) for the skin, 83.3%(5/6) for the liver and 76.9%(10/13) for the lung. The highest rate of complete organ response was 95.8% for skin. Eight patients (17%) developed cytopenia, of which 2(4.2%) were with a decrease of 3-4 degree hemoglobin. Recrudescence of cytomegalovirus occurred in 3 patients (6.4%). After withdrawal of Ruxolitinib, 6 patients (12.7%) had recurrence of cGVHD. The median time to relapse was 35.5(7-90) days. All of their conditions were improved after addition of Ruxolitinib. The median time of response was 7(5-14) days. The median follow-up was 208(33-412) days. Three patients(6.4%) died, and all of them died of severe pulmonary infection. Three patients (6.4%) had relapse of primary disease. The 6-month overall survival rate was 95.7%. Conclusion: Low-dose Ruxolitinib has good efficacy and safety in the treatment of cGVHD.

Abstract
Objective: To explore whether the atrial septal defect(ASD) size, the type of occlusion umbrella selected, and the morphological changes after release of occlusion umbrella affect the headache symptoms of ASD patients after operation. Methods: A total of 567 ASD ptients, who underwent successful implantion with a single occlude from January 2014 to December 2017 in General Hospital of Northern Theater Command were enrolled. The patients were divided into symptomatic group and asymptomatic group according to the presence or absence of headache symptoms after occlusion. X-ray catheter calibration method was used to measure the diameter(d), thickness(L), maximum diameter of the left umbrella surface after release(D2) and the value of i (i = D2/L). Risk factors related to headache were analyzed by multivariate logistic regression analysis. linear regression analysis was used to detect the relationship between the type of occluder umbrella and ASD diameter in asymptomatic group. Results: A total of 567 patients with one occluder umbrella were included, and 148(26.1%) cases were male. The age was (34.4±19.4) years old. The follow-up time was (12.7±2.8) months. There were 51 cases in the symptomatic group and 516 cases in the asymptomatic group. In 29 patients who were treated by extending the course or increasing the dose of aspirin, the symptoms disappeared or improved. There was no significant difference in the maximum ASD diameter (TTE measured) and the size of occluder between the symptomatic group and asymptomatic group(both P>0.05). The value of d ((19.80±6.67)mm vs.(17.40±7.28) mm, P=0.041) D2 ((43.29±7.41)mm vs. (39.20±9.59)mm, P=0.013)and L((13.06±3.72)mm vs. (10.19±2.90) mm,P=0.025) of the symptomatic group were all higher than that of the asymptomatic group,while the i value was smaller((3.54±0.88)vs.(3.99±0.93),P=0.010). The results of multivariate logistic regression analysis showed that the value of L(OR=1.286,95%CI 1.176-1.406, P=0.002) and the value of i(OR=0.916,95%CI 0.867-0.968, P<0.001) were independent factors of headache symptoms in patients after ASD occlusion, while the value of d and the value of D2 were not independent factors (both P>0.05). Linear equations obtained from asymptomatic patients showed the size of occluder =1.121×the maximum ASD diameter of TTE measured +6.414. Conclusions: There is no correlation between the symptoms with the expanded diameter and the maximum diameter of left umbrella's surface after released. The Postoperative discomfort symptoms is significantly correlated to the thickness of the occluder and the value of i. It is suggested that headache could be induced by the oversized occlude, thus choosing the appropriate size of the occluder is essential to reduce the occurrence of postoperative headache symptoms. Increasing the size of occluder because of worrying about the abscission and removal of the occlude is unreasonable. The antiplatelet therapy should also be strengthened to reduce the occurrence of symptoms and improve the symptoms of the patients if the occluder's size is too large. This regression equation (The size of occluder =1.121 × the maximum ASD diameter of TTE measured +6.414) could be used as a reference for the suitable selection of ASD occluder.

Abstract
Alpinetin, the main active ingredient in the Chinese medicinal herb Alpinia katsumadai Hayata, has been found to have anticancer activity. However, the therapeutic efficacy of signalling cascades modulated by alpinetin remains unknown. Here, we showed that alpinetin provoked mitochondria‐associated apoptosis in a dose‐dependent manner in breast cancer cells. Mechanistic investigations revealed that alpinetin dampens hypoxia‐inducible factor‐1α (HIF‐1α) signalling due to a lack of NF‐κB activation through reduced mitochondrial reactive oxygen species (ROS) production, decreasing HIF‐1α transcription. In vivo, we also found alpinetin led to significant tumour regression by inhibiting NF‐κB pathway. Overall, our work uncovers a ROS/NF‐κB/HIF‐1α axis‐dependent mechanism underlying the anticancer effects of alpinetin and suggests that alpinetin could act as a novel therapeutic agent against breast cancer.

Abstract
Abstract Objective To investigate the factors affecting changes of Symptom Check List-90 (SCL-90) of patients with traumatic subdural effusion. Methods One hundred and forty-two cases of patients with traumatic subdural effusion from the Center of Forensic Identification, Wannan Medical College collected from 2007-2018 were tested with SCL-90. The differences between SCL-90 results and the national norm and the influences of gender, age, education level, the number of effusion sites and location on SCL-90 results were analyzed. Results The differences between the scores of somatization, interpersonal sensitivity, depression, anxiety, hostility, terror, paranoia and psychosis factors and total mean scores in SCL-90 of traumatic subdural effusion and that of the national norm had statistical significance (P<0.05). The differences in depression and hostility factor scores between males and females had statistical significance (P<0.05). The differences in compulsion, anxiety and terror factor scores and total mean scores among different age groups had statistical significance (P<0.05). The differences in hostility, paranoia and psychosis factors among patients with different degrees of education had statistical significance (P<0.05). The differences in depression, anxiety, hostility and terror factor scores and total mean scores among single-site group, double-site group and multi-site group had statistical significance (P<0.05). The differences in somatization, depression and anxiety factor scores and total mean scores between the right cerebral hemisphere group and the left cerebral hemisphere group and bilateral hemisphere group had statistical significance (P<0.05). Conclusion Traumatic subdural effusion can cause certain psychological changes, which are related to the primary trauma of arachnoid tear as well as the number and location of effusion sites. Attention should be paid to the influence of the above factors during the assessment of psychological symptoms.

Abstract
BACKGROUND/AIM Low residue diet (LRD) has a similar quality of bowel preparation with clear liquid diet before colonoscopy, but improved patient tolerance. However, the optimal LRD duration is still controversial. In this study, we have compared the effect of a 1-day LRD and 2-day LRD on the quality of bowel preparation and patient tolerance. PATIENTS AND METHODS Our prospective, randomized, single-blind trial, single-blind, trial compared two dietary regimens administered the day before colonoscopy. All patients were administered PEG-ES and simethicone for bowel preparation. The primary outcome measure was bowel preparation quality. The secondary outcome measures were insertion time, withdrawal time, polyp detection rate, patient tolerance, and willingness to use the same diet for bowel preparation again. Bowel preparation quality was evaluated using the Boston bowel preparation scale (BBPS). Patient tolerance was evaluated using a hunger-comfort scale. RESULTS There was no significant difference in bowel preparation quality between the 2 groups. The 1-day LRD group had a BBPS score of 6.48 ± 1.59 points, while the 2-day LRD group had a score of 6.42 ± 1.06 points (P > 0.05). The groups reported similar colonoscope insertion times, withdrawal times, polyp detection rates and patient tolerance scores (hunger-comfort scores). The numbers of patients who reported that compliance as easy or very easy were 126 (78.2%) in the 1-day group versus 88 (55.0%) in the 2 day group (P < 0.05) and the numbers who were willing to use the diet again in the future were 154 (95.7%) in the 1-day group versus 131 (81.9%) in the 2 day group (P < 0.05). CONCLUSION LRD duration (1 day or 2 days) had no significant effect on bowel preparation quality. Patients in the 1-day LRD group had higher tolerance and satisfaction levels than patients in the 2-day LRD group. However, overall satisfaction was higher with the 1-day LRD group than with the 2-day LRD group.

Abstract
Grifola frondosa is an edible and medicinal mushroom with great nutritional values and bioactivities. In the present study, a soluble homogeneous β-glucan, GFPS, with high molecular mass of 5.42 × 106 Da was purified from the fruit bodies of Grifola frondosa using 5% cold NaOH. The structure of GFPS was determined with FT-IR, NMR, and monosaccharide composition analysis, and was identified to be a β-D-(1-3)-linked glucan backbone with a single β-D-(1-6)-linked glucopyranosyl residue branched at C-6 on every third residue. Our results indicated that GFPS had a triple helical structure and could form complex with polydeoxyadenylic acid (poly[A]). Further studies demonstrated that GFPS could interact with poly[A] moiety of a designed antisense oligonucleotide (ASO) targeting the primary transcript of proinflammatory cytokine TNFα (TNFα-A60). This GFPS-based complex could incorporate TNFα-A60 into the macrophage cells via dectin-1 receptor and attenuate lipopolysaccharide-induced secretion of TNFα. Our results suggested that GFPS could be applied to deliver therapeutic oligonucleotides for the treatment of diseases such as inflammation and cancers.

Abstract
SummaryObstructive sleep apnea (OSA) is closely related to the development of various diseases. Hypoxic perfusion caused by OSA can mediate the occurrence of inflammatory reactions or aggravate metabolic disorders to affect intestinal microecological balance. Intestinal bacteria can participate in the development of inflammatory reaction or metabolic disorder by itself or its components, and the oxidative stress reaction of the body develops in a vicious circle. The mechanism has not yet been fully elucidated, so we reviewed the research progress on OSA and intestinal microecological balance.

Abstract
Hyperoside (quercetin 3-o-β-d-galactopyranoside) is one of the flavonoid glycosides with anti-inflammatory, antidepressant, and anti-cancer effects. But it remains unknown whether it had effects on breast cancer. Here, different concentrations of hyperoside were used to explore its therapeutic potential in both breast cancer cells and subcutaneous homotransplant mouse model. CCK-8 and wound healing assays showed that the viability and migration capability of Michigan Cancer Foundation-7 (MCF-7) and 4T1 cells were inhibited by hyperoside, while the apoptosis of cells were increased. Real-time quantitative PCR (qRT-PCR) and western blot analysis were used to detect mRNA and the protein level, respectively, which showed decreased levels of B cell lymphoma-2 (Bcl-2) and X-linked inhibitor of apoptosis (XIAP), and increased levels of Bax and cleaved caspase-3. After exploration of the potential mechanism, we found that reactive oxygen species (ROS) production was reduced by the administration of hyperoside, which subsequently inhibited the activation of NF-κB signaling pathway. Tumor volume was significantly decreased in subcutaneous homotransplant mouse model in hyperoside-treated group, which was consistent with our study in vitro. These results indicated that hyperoside acted as an anticancer drug through ROS-related apoptosis and its mechanism included activation of the Bax-caspase-3 axis and the inhibition of the NF-κB signaling pathway.
