Abstract
BACKGROUND The management of hepatoblastoma (HB) becomes challenging when the tumor remains in close proximity to the major liver vasculature (PMV) even after a full course of neoadjuvant chemotherapy (NAC). In such cases, extreme liver resection can be considered a potential option.
AIM To explore whether computer-assisted three-dimensional individualized extreme liver resection is safe and feasible for children with HB who still have PMV after a full course of NAC.
METHODS We retrospectively collected data from children with HB who underwent surgical resection at our center from June 2013 to June 2023. We then analyzed the detailed clinical and three-dimensional characteristics of children with HB who still had PMV after a full course of NAC.
RESULTS Sixty-seven children diagnosed with HB underwent surgical resection. The age at diagnosis was 21.4 ± 18.8 months, and 40 boys and 27 girls were included. Fifty-nine (88.1%) patients had a single tumor, 39 (58.2%) of which was located in the right lobe of the liver. A total of 47 patients (70.1%) had PRE-TEXT III or IV. Thirty-nine patients (58.2%) underwent delayed resection. After a full course of NAC, 16 patients still had close PMV (within 1 cm in two patients, touching in 11 patients, compressing in four patients, and showing tumor thrombus in three patients). There were 6 patients of tumors in the middle lobe of the liver, and four of those patients exhibited liver anatomy variations. These 16 children underwent extreme liver resection after comprehensive preoperative evaluation. Intraoperative procedures were performed according to the preoperative plan, and the operations were successfully performed. Currently, the 3-year event-free survival of 67 children with HB is 88%. Among the 16 children who underwent extreme liver resection, three experienced recurrence, and one died due to multiple metastases.
CONCLUSION Extreme liver resection for HB that is still in close PMV after a full course of NAC is both safe and feasible. This approach not only reduces the necessity for liver transplantation but also results in a favorable prognosis. Individualized three-dimensional surgical planning is beneficial for accurate and complete resection of HB, particularly for assessing vascular involvement, remnant liver volume and anatomical variations.

Abstract
Calix[8]arene has been used as a promising type of macrocyclic ligand for the construction of multinuclear metal-oxo clusters (MOCs), but not for zirconium/hafnium-oxo clusters (Zr/HfOCs). In this paper, we report the first series of ZrOCs (HfOCs) based on calix[8]arene: Zr4, Zr8, Hf4, and Hf8. Zr8/Hf8 has a rhombohedral conformation and can be regarded as a derivative of the octahedral Zr6 cluster. Remarkably, I2 adsorption experiments indicate that Zr4 (Zr8) adsorbs much faster than Hf4 (Hf8). Density functional theory (DFT) calculations show that metallic Zr atoms interact more strongly with I2 than metallic Hf atoms. The successful application of calix[8]arene for the synthesis of well-defined ZrOCs (HfOCs) shows a bright future for MOCs protected by macrocyclic ligands.

Abstract
The O-linked-β-N-acetylglucosamine (O-GlcNAc) glycosylation (O-GlcNAcylation) is a critical post-translational modification that couples the external stimuli to intracellular signal transduction networks. However, the critical protein targets of O-GlcNAcylation in oxidative stress-induced apoptosis remain to be elucidated. Here, we show that treatment with H2O2 inhibited O-GlcNAcylation, impaired cell viability, increased the cleaved caspase 3 and accelerated apoptosis of neuroblastoma N2a cells. The O-GlcNAc transferase (OGT) inhibitor OSMI-1 or the O-GlcNAcase (OGA) inhibitor Thiamet-G enhanced or inhibited H2O2-induced apoptosis, respectively. The total and phosphorylated protein levels, as well as the promoter activities of signal transducer and activator of transcription factor 3 (STAT3) and Forkhead box protein O 1 (FOXO1) were suppressed by OSMI-1. In contrast, overexpressing OGT or treating with Thiamet-G increased the total protein levels of STAT3 and FOXO1. Overexpression of STAT3 or FOXO1 abolished OSMI-1-induced apoptosis. Whereas the anti-apoptotic effect of OGT and Thiamet-G in H2O2-treated cells was abolished by either downregulating the expression or activity of endogenous STAT3 or FOXO1. These results suggest that STAT3 or FOXO1 are the potential targets of O-GlcNAcylation involved in the H2O2-induced apoptosis of N2a cells.

Abstract
OBJECTIVE Interleukin-18 (IL-18) is a proinflammatory cytokine. This study aims to determine whether there is a causal relationship between circulating IL-18 concentrations and the risk of inflammatory and autoimmune diseases. METHODS We collected significant single nucleotide polymorphisms (SNPs) associated with circulating IL-18 levels (p < 5 × 10-8) as instrumental variables (IVs) from a genome-wide association study (GWAS) involving 21,758 individuals of European descent. We mainly employed the inverse-variance weighed (IVW) method of two-sample Mendelian randomization (TSMR) analysis to estimate the causality of circulating IL-18 levels on inflammatory and autoimmune diseases. RESULTS The IVW method results showed evidence of a causal relationship between IL-18 and the risk of systemic lupus erythematosus (SLE) (OR = 1.32; 95% CI 1.15, 1.50; p < .001) and type 1 diabetes (T1D) (OR = 1.22; 95% CI 1.06, 1.42; p = .007) in individuals of European ancestry. No significant heterogeneity or horizontal pleiotropy for SLE and T1D was detected. The sensitivity analysis, which involved removing confounding SNP, produced similar results for SLE and T1D. The results of sensitivity analysis using leave-one-out method indicated no single SNP significantly influenced the analysis results. However, we did not find any significant findings for multiple sclerosis, psoriasis, asthma, and osteoarthritis. CONCLUSIONS Our analyses suggest that circulating IL-18 is significantly related to SLE and T1D and may serve as a potential target for the treatment of these diseases.

Abstract
Objective The aim of this study is to examine the distribution and features of gastroscopy in northern Xinjiang, a province in China. Methods We included a group of 895 patients diagnosed with digestive diseases at Urumqi Friendship Hospital and analyzed their gastroscopic results and baseline data. Results Among patients aged 12 to 86 years in the specified region, females exhibited a heightened susceptibility to esophageal-gastrointestinal and intestinal disorders compared to males. The mean age for chronic gastritis onset was determined to be 54.79 years. In the context of esophageal-gastric-intestinal disorders, the distribution across various ethnic groups manifested as follows: the Han, Uygur, Hui, and Kazakh populations comprised 53.97%, 23.91%, 7.15%, and 3.46%, respectively. Through principal component-based dimension reduction analysis, we identified chronic non-atrophic gastritis with erosive gastritis, duodenal bulb inflammation, and chronic non-atrophic gastritis (predominantly in the gastric antrum) as pivotal factors contributing to differences in hiatal hernia. Multiple linear regression models were established for different ethnic groups, duodenal bulb inflammation, and hiatal hernia by age. The results revealed a heightened risk of duodenal bulb inflammation (P < 0.01) in Han, Kazakh, Hui, Mongolian, and Uygur women, while the risk of hiatal hernia exhibited a positive correlation with age (P = 0.001). Conclusion Among patients undergoing gastrointestinal examinations in northern Xinjiang, the most prevalent pathological condition was identified as chronic gastritis. Notably, within this subgroup, the prevalence of duodenal bulb inflammation was found to be greater in women than in men. The ethnic composition within this context encompassed patients from the Han, Kazakh, Hui, and Mongolian ethnic groups. Furthermore, a positive correlation was identified between the incidence of esophageal hiatal hernia and age.

Abstract
Three unusual oleanane-derived triterpenoids, stytontriterpenes A-C (1-3), were isolated from the resin of Styrax tonkinensis together with an oleanane-lactone (stytontriterpene D, 4). Their structures and absolute configurations were characterised using a combination of spectroscopic analysis, electronic circular dichroism, and theoretical calculations. 1 and 2 belong to nor-oleanane with rare spiro D/E rings and 3 contains one infrequent C32 scaffold. 1 considerably suppressed the number of adhered leukemic monocytes (THP-1) to human umbilical vein endothelial cells and attenuated the upregulations of mRNA and protein levels of intracellular adhesion molecule-1 and vascular cell adhesion molecule-1 at 5 μM, suggesting that 1 might be a promising anti-vascular inflammatory chemical for atherosclerosis therapy. Plausible biosynthetic pathways for 1-4 are also proposed.

Abstract
AIM To characterize the ophthalmic clinical phenotype of a family with retinitis pigmentosa (RP) and closed-angle glaucoma and to detect pathogenic genes and mutation sites causing RP in this family. METHODS Ophthalmic clinic performance was examined in detail in 8 enrolled family members. Genomic DNA was extracted from the peripheral blood of 4 family members for whole-exome sequencing (WES) to select potential genetic mutations whose structures were identified by bioinformatics analysis. Then, Sanger sequencing was used in 12 family members and control group members to validate and confirm the disease-causing mutation loci, and we analyzed the genotype-phenotype relationships. RESULTS The known c.512C>T (p.P171L) mutation in the rhodopsin (RHO) gene was only found in afflicted family members and was confirmed by WES and Sanger sequencing as the pathogenic mutation in this family. In addition to being diagnosed with RP, family member III:4 was found to have bilateral closed-angle glaucoma, high myopia, and concurrent cataracts, and family members II:2 and II:4 had pathological changes of anterior chamber angle narrowing. Family members IV:3 and IV:4 were found to have retinoschisis. CONCLUSION Glaucoma and related pathological changes, such as retinoschisis, in family members are preliminarily considered RP complications caused by RHO mutation.

Abstract
PURPOSE To investigate the inhibitory effect of paeoniflorin(PF) with different concentrations on CAL27 cells of tongue squamous cell carcinoma in vitro and its possible mechanism. METHODS CCK-8 technique and clone formation trial were used to detect the effect of PF on the proliferation and clone formation of CAL27 cells. Scratch test and Transwell method was used to detect the effects of PF on migration and invasion of CAL27 cells. Staining of Hoechst33342 was employed to evaluate the influence of PF on apoptosis of CAL27 cells, while Western blot was utilized to investigate the effect of PF on the expression of NF-κB pathway related proteins and EMT related proteins. The effect of PF on NO production in CAL27 cells was detected by nitric oxide detection kit. Statistical analysis was performed with SPSS 27.0 software package. RESULTS PF inhibited proliferation, migration, and invasion of CAL27 cells in vitro in a concentration-dependent way. Moreover, PF caused apoptosis of CAL27 cells. PF impeded NF-κB pathway activity, decreased the expression of P-P65, further reduced the expression of iNOS and MMP-9, suppressed the production of NO, and concurrently inhibited Vimentin,promoted E-cadherin. CONCLUSIONS Paeoniflorin inhibits the proliferation, migration and invasion of CAL27 cells, which may play an anti-cancer role by inhibiting the activation of NF-κB pathway and EMT.

Abstract
Background The pain-fatigue-sleep disturbance symptom cluster is commonly experienced by breast cancer patients, and a variety of nonpharmacological interventions are used to treat this symptom cluster. Objective To compare the efficacy of nonpharmacological interventions in improving the symptoms of the pain-fatigue-sleep disturbance symptom cluster in breast cancer patients. Methods A comprehensive literature search was conducted in the PubMed, EMBASE, Cochrane Library, CINAHL, CNKI, and Wanfang databases to identify randomized controlled studies from database inception to May 2022. Two reviewers independently performed data retrieval and risk of bias assessments. The consistency model was used to conduct network meta-analyses (NMA) based on the frequentist framework to assess the interventions, which were ranked by the surface under the cumulative ranking curve (SUCRA). Finally, the CINeMA application was used to evaluate the results of the NMA and the evidence of quality. The results Twenty-three eligible studies assessing 14 interventions were included. According to SUCRA values, among the management effects of the three symptoms, the effect of progressive muscle relaxation (PMR) ranked first, followed by mindfulness-based stress reduction (MBSR). The overall evidence quality of our study ranges from very low to moderate. Conclusion PMR and MBSR were effective interventions for the pain-fatigue-sleep disturbance symptom cluster in breast cancer patients. Clinical recommendations prioritize PMR for symptom management, followed by MBSR. However, this should be interpreted cautiously, as the confidence in the evidence was not high.

Abstract
Mycobacterium tuberculosis (Mtb) infection elicits macrophage polarization into M2 phenotype to block the host's protective immune response. However, it remains unclear how Mtb regulates macrophage polarization. Recent studies have suggested that noncoding RNA may play a role in macrophage polarization. In this study, we investigated the potential involvement of circTRAPPC6B, a circular RNA that is downregulated in tuberculosis (TB) patients, in regulating macrophage polarization. We found that Mtb infection downregulated M1-related IL-6 and IL-1β while highly expressed M2-related CCL22 and CD163. Overexpressed circTRAPPC6B had switched Mtb-infected macrophages from M2- to M1-like phenotype, accompanied by upregulation of IL-6 and IL-1β. Meanwhile overexpressed circTRAPPC6B significantly inhibited Mtb growth in macrophages. Our findings suggest that circTRAPPC6B may regulate macrophage polarization by targeting miR-892c-3p, which is highly expressed in TB patients and M2-like macrophages. And miR-892c-3p inhibitor decreased intracellular Mtb growth in macrophages. Thus, TB-inhibited circTRAPPC6B could specifically induce IL-6 and IL-1β expression to switch/antagonize Mtb-induced macrophage polarization from M2- to M1-like phenotype by targeting miR-892c-3p, leading to enhanced host clearance of Mtb. Our results reveal a potential role for circTRAPPC6B in regulating macrophage polarization during Mtb infection and provide new insights into the molecular mechanisms underlying host defense against Mtb.

Abstract
BACKGROUND Ganglioneuroblastoma (GNB) is a peripheral neuroblastoma (NB) with malignant degree between highly malignant NB and benign ganglioma (GN). Pathology is the gold standard of diagnosis. Although GNB is not uncommon in children, biopsy alone may lead to an inaccurate diagnosis, especially for giant tumors. However, surgical resection may be associated with significant complications. Here, we report a case of computer-assisted surgical resection of a giant GNB in a child and successful rescue of the inferior mesenteric artery.
CASE SUMMARY A 4-year-old girl was admitted to our department for a giant retroperitoneal lesion, which was considered to be an NB by her local hospital. The symptoms of the girl disappeared spontaneously without treatment. On physical examination, a mass of about 10 cm × 7 cm could be palpated in her abdomen. Ultrasonography and contrast-enhanced computed tomography performed in our hospital also showed an NB, and there was a very thick blood vessel inside the tumor. However, aspiration biopsy revealed GN. Surgical resection is the best treatment option for this giant benign tumor. For precise preoperative evaluation, three-dimensional reconstruction was performed. It was clear that the tumor was close to the abdominal aorta. The superior mesenteric vein was pushed forward, and the inferior mesenteric artery passed through the tumor. Because GN generally does not invade blood vessels, we split the tumor with a CUSA knife during the operation and found that there was indeed a straight and intact vascular sheath. Arterial pulsation was observed in the completely exposed inferior mesenteric artery. The pathologists interpreting the tissue finally diagnosed it as a mixed GNB (GNBi), which is more malignant than GN. However, both GN and GNBi usually have a good prognosis.
CONCLUSION This was a case of successful surgical resection of a giant GNB, and aspiration biopsy underestimated the pathological staging of the tumor. Preoperative three-dimensional reconstruction assisted with the radical resection of the tumor and rescue of the inferior mesenteric artery.

Abstract
BACKGROUND Rhabdomyosarcoma (RMS) is a highly malignant tumor that originates from myogenic progenitor cells. OBJECTIVE To investigate the magnetic resonance imaging (MRI) characteristics of prostate embryonal rhabdomyosarcoma (ERMS). METHODS We retrospectively analyzed the clinical and MRI imaging data of 9 cases of prostate ERMS that were confirmed pathologically. The patients were aged between 14∼49 years with a median age of 27 years, and they all underwent MRI, diffusion-weighted imaging (DWI), and dynamic contrast-enhanced MRI (DCE-MRI). RESULTS The MRI scan of the lesions showed an irregular shape, mixed signals, uneven equal/long T1 signal and an equal/long T2 signal, cystic necrosis in 9 cases and hemorrhage in 6 cases; DWI and ADC images showed a mixed high/low signal, and the tumor parenchyma showed ADC low signal, with an average ADC value of 0.666 × 10-3 mm2/s. There were 5 cases of DCE-MRI TIC type II and 4 cases of DCE-MRI TIC type I. The average value of Tpeak was 120 s and the average value of MCER was 172.3%. After the enhancement, the signal of tumor enhancement was uneven, and showed patchy and reticular enhancement, however, the cyst degeneration, necrosis area, and hemorrhage focus were not enhanced. There were 3 cases with multiple pelvic lymph nodes and 1 case with multiple bone metastases. CONCLUSION The MRI manifestations of prostate ERMS have certain characteristics, and the combination of DWI and DCE-MRI are helpful in the diagnosis.

Abstract
To analyze the clinical and endoscopic characteristics of colorectal polyps in children, and to explore the detection rate, age and gender distribution characteristics, endoscopic treatment effect and follow-up monitoring of colorectal polyps in children, so as to provide reference for disease management of colorectal polyps in children. The clinical and endoscopic characteristics of children with colorectal polyps in Xi 'an Children's Hospital from January 2019 to December 2019 were retrospectively analyzed. The patients were divided into 5 groups according to age (y): 0<y<1 years, 1≤ y<4 years, 4≤ y<7 years, 7≤ y<12 years, and 12≤ y ≤18 years. Independent sample t test, Pearson Chi-square test (χ2) were used to compare groups' differences. The results showed that a total of 724 colonoscopies were completed in 2019, and 160 colorectal polyps were diagnosed, with a detection rate of 22.10%. Among the children with colorectal polyps, 105 were males, accounting for 65.62%, and 55 were females, accounting for 34.38%. The detection rate of male colorectal polyps was 22.68%, and the detection rate of female colorectal polyps was 21.08%. There was no significant difference in the detection rate of colorectal polyps between males and females (χ2 = 0.25, P =0.617). Children with colorectal polyps were most common in the age group of 1≤ y<4 years, 72 cases, accounting for 41.14%(72/175). The detection rate of colorectal polyps in different age groups was statistically significant (χ2=73.929, P<0.05). The main symptom of children with colorectal polyps was hematochezia, accounting for 87.5% (140/160). Colorectal polyps were mainly single polyps in 140 patients, accounting for 87.50%, 15 patients had 2-4 polyps, accounting for 9.38%, and 5 patients had 5 or more polyps, accounting for 3.12%. A total of 210 polyps were removed, and the most common site of polyps was rectum, 123 polyps, accounting for 58.57% (123/210). 111 (52.86%, 111/210) of them were 1 cm to 2 cm in diameter. The Yamada classification was mainly type Ⅲ, 114 pieces, accounting for 54.29% (114/210). Among the 210 polyps with diameter ≥0.5 cm, 165 were removed by endoscopic mucosal resection, accounting for 78.57% (165/210). There were 23 patients with postoperative complications, including hematochezia, abdominal pain, fever, vomiting, diarrhea, dizziness, and no gastrointestinal perforation. Juvenile polyps were the main pathological type, accounting for 88.13% (141/160). The children with juvenile polyps were followed up for 3-30 months, and recurrence was considered in 2 of them. In conclusion, the detection rate of colorectal polyps in children aged 1≤ y<4 years is high, and hematochezia is the main clinical manifestation. Standardized endoscopic treatment and follow-up monitoring are very important for children with colorectal polyps.

Abstract
OBJECTIVE Previous observational studies demonstrated that a subset of patients with systemic lupus erythematosus (SLE) have markedly short telomere length (TL) in leukocytes. The purpose of this study is to test whether leukocyte TL is causally associated with risk of SLE. METHODS A two-sample Mendelian randomization (TSMR) analysis was applied to estimate causality of TL on SLE in European populations. A replication TSMR study using Asian genetic data was also conducted. A backward MR analysis was then performed to test effects of SLE on TL. The autoantibodies targeting telomere-associated protein (TERF1 autoantibodies) were detected in SLE, healthy controls and rheumatoid arthritis (RA). RESULTS The results of inverse-variance weighted method (OR=2.96; 95% CI 1.58, 5.55; P<0.001) showed strong evidence for casual relationship between longer TL and risk of SLE in people with European ancestry. The outcomes of MR-Egger regression (OR=29.46, 95% CI 3.02, 287.60; P=0.033), and MR-PRESSO (OR=3.62; 95% CI 2.03, 6.46; P=0.002) also showed that longer TL was significantly associated with increased risk of SLE in European population. Sensitivity analyses using different methods and summary data sets showed that the results were still broadly consistent. Replication MR study using Asian genetic data yielded similar findings. However, the backward MR analysis showed that genetically predicted SLE was not causally associated with TL. In addition, we found that TERF1 autoantibodies were present in 2/40 (5.0%) patients with SLE. CONCLUSION In contrast with previous observational studies, MR analyses found that longer TL is significantly associated with increased risk of SLE.

Abstract
Objective: To investigate the effect of preoperative serum creatinine (Scr) level on the prognosis of patients with early cervical adenocarcinoma (ADC) and its predictive value. Methods: A retrospective review was performed on 199 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage ⅠA1-ⅡA1 and pathology-proven invasive ADC from January 2005 to December 2015. Patients were followed up by phone and outpatient, with a median follow-up time 77.5 (57.0, 114.0) months, 11 cases (5.5%) were missing, 19 cases (10.1%) recurred, and 17 cases (9.0%) died. Multivariate analysis was performed by Cox regression model to analyze the related factors of the prognosis of ADC patients. The optimal cut-off point was determined by the analysis of receiver operating characteristics (ROC), and the predictive value of related factors for prognosis was evaluated by the area under the curve (AUC). Results: The median age of 199 patients was 44.0 (39.0-50.0) years. Overall, 16 patients (8.0%) were stage ⅠA1; 4 patients (2.0%) were stage ⅠA2; 147 patients (74.0%) were stage ⅠB1; 13 patients (6.5%) were stage ⅠB2; 19 patients (9.5%) were stage ⅡA1. The multivariate analysis showed that FIGO stage [4.570 (1.625-12.854)] and elevated Scr [1.065 (1.006-1.128)] were correlated with DFS in patients with early ADC, as well as correlated with OS [4.412 (1.458-13.350) and 1.076 (1.012-1.144), respectively (all P<0.05)]. The optimal cut-off point of Scr level was 75.2 μmoI/L. The AUC showed that the Scr level was a predictor of DFS (AUC=0.677, 95%CI: 0.608-0.742, P=0.006) and OS (AUC=0.677, 95%CI: 0.607-0.741, P=0.012). Conclusions: The preoperative Scr level independently predicts the prognosis of early-stage ADC; patients with Scr levels>75.2 μmoL/L might require more follow-up and adjuvant treatment, as they might have a poorer prognosis.

Abstract
MYC proto-oncogene (MYC), a first oncogenic nuclear transcription factor isolated from the human genome, belongs to the helix loop helix/leucine zipper protein family (bHLHzip). MYC plays an important part in the process of various physiological and biochemical of vertebrate, such as cell growth, proliferation, cycle, and autophagy. However, its molecular regulation mechanism and function in invertebrates are still unclear. In this study, a novel transcription factor MYC gene was screened, cloned, and characterized from Penaeus vannamei. The open reading frame of PvMYC was 1593bp, encode a polypeptide of 530 amino acids with molecular weight of 58.5 kDa, and a theoretical PI of 5.75. The results of tissue distribution showed that PvMYC was constitutively expressed in all detected tissues, and highest expression in hepatopancreas. The expression level of PvMYC up-regulated significantly and responded to low temperature stress by nuclear ectopic after low temperature stress. Overexpression of PvMYC in shrimp hemocytes negatively regulated the expression of Beclin-1 and reduced the conversion from LC3I to LC3II, yet p62 was decreased significantly. Meanwhile, RAPA eliminated the inhibition of autophagy caused by overexpression of PvMYC. ROS levels and autophagy flux showed the similar trend under low temperature stress after silencing PvMYC. The expression levels of Beclin-1, key ATG gene and LC3II increased significantly, while p62 decreased significantly under the same conditions. In addition, the Total hemocyte count (THC) decreased sharply, and accelerated the injury of hepatopancreas under low temperature stress after silencing PvMYC. Collectively, these results suggest that PvMYC has vital role in the cold adaptation mechanism of P. vannamei by negatively regulating autophagy.

Abstract
PURPOSE To investigate the effect of Osthole (OST) on lipopolysaccharide (LPS)-induced macrophage polarization and inflammatory reaction. METHODS The effect of different concentrations of OST on proliferative activity of RAW264.7 macrophages was examined by CCK-8 method; the effect of OST at different concentrations (6.25, 12.5 and 25 μmol/L) on macrophage polarization and inflammation was investigated by using intracellular reactive oxygen species (ROS) detection kit (DCFH-DA), immunofluorescence staining, q-PCR and flow cytometry. The effects of OST on macrophage polarization and inflammatory responses were investigated by immunoblotting of proteins. Graphpad prism 8.0 software package was used for statistical analysis of the data. RESULTS CCK-8 results showed that OST was not significantly cytotoxic to RAW264.7 at less than 25 μmol/L, immunofluorescence and q-PCR results showed that OST at 6.25, 12.5 and 25 μmol/L inhibited the expression of inflammatory factors in M1 macrophages, and iNOS, TNF-α, CCR7 were reduced in a concentration-dependent manner, and effectively upregulated the expression of M2 inflammatory factors IL-10, Arg-1 and CD206. Flow cytometry showed that OST effectively inhibited the expression of LPS-induced M1 marker CD86 in macrophages. CONCLUSIONS OST can regulate lipopolysaccharide-induced M1 macrophages polarization and reduce inflammatory reaction.

Abstract
The understanding of the engrafted cell behaviors such as the survival, growth and distribution is the prerequisite to optimize cell therapy, and a multimodal imaging at both anatomical and molecular levels is designed to achieve this goal. We constructed a lentiviral vector carrying genes of ferritin heavy chain 1 (FTH1), near-infrared fluorescent protein (iRFP) and enhanced green fluorescent protein (egfp), and established the induced pluripotent stem cells (iPSCs) culture stably expressing these three reporter genes. These iPSCs showed green and near-infrared fluorescence as well as the iron uptake capacity in vitro. After transplanted the labeled iPSCs into the rat brain, the engrafted cells could be in vivo imaged using magnetic resonance imaging (MRI) and near-infrared fluorescent imaging (NIF) up to 60 days at the anatomical level. Moreover, these cells could be detected using EGFP immunostaining and Prussian blue stain at the cellular level. The developed approach provides a novel tool to study behaviors of the transplanted cells in a multi-modal way, which will be valuable for the effectiveness and safety evaluation of cell therapy.

Abstract
BACKGROUND Atrial fibrillation (AF) is a very common type of cardiac arrhythmia that threatens public health. Aging is an independent AF risk factor. However, the mechanism of age-related AF remains unclear. METHODS A total of 36 Beagle dogs were selected and divided into three groups (12 in each group): two groups were 9-year-old aged dogs, and one group was 4-year-old adult dogs. Electrophysiological testing was employed to determine if modeling is successful. Patch-clamp technique was employed to measure the If current. The expression of protein and mRNA related to If current were also tested. Collagen deposition was observed with the use of Masson staining. RESULTS Aging resulted in a higher collagen deposition percentage in the left atrium. The hyperpolarization-activated cyclic nucleotide-gated (HCN)2 and HCN4 expressions were increased in the atria and pulmonary veins but decreased in the sinus node of the aged group. Moreover, in the aged group, the left atrium mRNA expressions of Kcnd2 (Potassium voltage-gated channel subfamily D member 2), Kcnh2, Kcnq1, Kcnj2, Kcnj11, and CACNA1H were significantly downregulated. The aged AF group also demonstrated sustained AF and significant changes in electrophysiological characteristics. The If current demonstrated an increased amplitude and was easier to activate in the aged AF group than in younger group. Finally, AF occurrence exacerbated aging-induced cardiac fibrosis, thereby aggravating the above-listed symptoms. CONCLUSION With age, the increase in atrial fibrosis affected the expression of the ion channels, thereby modulating the If current. Moreover, AF also further exacerbated the degree of atrial fibrosis.

Abstract
To assess the positive predictive value (PPV) of extended noninvasive prenatal testing (NIPT-plus) for fetal chromosomal abnormalities. This retrospective research enrolled 511 cases of pregnant women with positive NIPT-plus results at the Obstetrics and Gynecology Hospital of Fudan University from May 2017 to January 2021. Karyotype analysis and chromosome microarray analysis (CMA) techniques was applied for verification. All cases were followed to determine their pregnancy outcome. The Chi-square test was used in PPV. 63 out of 511 refused prenatal diagnosis after counseling, 448 pregnant women with prenatal diagnosis showed that the PPVs of NIPT-plus test for fetal trisomy 21, 18 and 13 (T21, T18, T13), sex chromosome aneuploidy (SCAs) and chromosome microdeletion/microduplication syndrome (MMS) were 86.0% (92/107), 79.5% (35/44), 54.5% (12/22), 39.5% (75/190), and 41.7% (30/72), respectively. The results revealed that the PPV was higher among older pregnant women compared to young pregnant women (77.8% vs. 51.9%,P<0.01). With increasing maternal age, the PPV of NIPT-plus presented increasing trends for T21, T13, and composite PPV except for T18 or SCAs. In addition, the termination rates for confirmed SCAs fetal karyotypes 45, X; 47, XXX; 47, XXY and 47, XYY were 11/11, 3/15, 91.7% (22/24) and 1/14, respectively. NIPT-plus can safely and effectively detect fetal chromosomal abnormalities and can be extended to MMS screening, significantly reducing the proportion of interventional prenatal diagnoses, and those with positive screening still require further confirmation.

Abstract
PURPOSE We aimed to assess the diagnostic performance of radiomics using machine learning algorithms to predict the methylation status of the O6-methylguanine-DNA methyltransferase (MGMT) promoter in glioma patients. METHODS A comprehensive literature search of PubMed, EMBASE, and Web of Science until 27 July 2021 was performed to identify eligible studies. Stata SE 15.0 and Meta-Disc 1.4 were used for data analysis. RESULTS A total of fifteen studies with 1663 patients were included: five studies with training and validation cohorts and ten with only training cohorts. The pooled sensitivity and specificity of machine learning for predicting MGMT promoter methylation in gliomas were 85% (95% CI 79%-90%) and 84% (95% CI 78%-88%) in the training cohort (n=15) and 84% (95% CI 70%-92%) and 78% (95% CI 63%-88%) in the validation cohort (n=5). The AUC was 0.91 (95% CI 0.88-0.93) in the training cohort and 0.88 (95% CI 0.85-0.91) in the validation cohort. The meta-regression demonstrated that magnetic resonance imaging sequences were related to heterogeneity. The sensitivity analysis showed that heterogeneity was reduced by excluding one study with the lowest diagnostic performance. CONCLUSION This meta-analysis demonstrated that machine learning is a promising, reliable and repeatable candidate method for predicting MGMT promoter methylation status in glioma and showed a higher performance than non-machine learning methods.

Abstract
Ficus hirta Vahl. has been reported to have hepatoprotective, antitumor, antibacterial functions, and is used to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Ammonia nitrogen is one of the most common environmental stress factors in aquaculture. Long-term exposure to high concentrations of ammonia nitrogen can induce oxidative stress and increase the risk of infections. However, whether Ficus hirta Vahl. has effect on ammonia nitrogen stress is unclear. In present study we report that Ficus hirta Vahl. improves the activity of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) of shrimp and decreases shrimp mortality caused by ammonia nitrogen stress. It is demonstrated that miR-2765 is negatively regulate the antioxidant capacity. We find that SOD was a direct target gene of miR-2765. MiR-2765 can bind to 3'-untranslated region (3'-UTR) of SOD to inhibit its transcription. Furthermore, Ficus hirta Vahl. down-regulates miR-2765 to activate the antioxidant capacity to alleviate the damage caused by ammonia nitrogen stress. Interestingly, overexpression of miR-2765 could attenuate the protective effect of Ficus hirta Vahl. on shrimp under ammonia nitrogen stress. These data indicate that Ficus hirta Vahl. alleviates the damage of ammonia nitrogen stress in shrimp by repressing miR-2765 and activating the antioxidant enzyme system. This study will provide a theoretical basis and a new perspective for assessing the toxicity mechanism of ammonia nitrogen in the process of farming on shrimp.

Abstract
Protein O-GlcNAcylation is a post-translational modification that links environmental stimuli with changes in intracellular signal pathways, and its disturbance has been found in neurodegenerative diseases and metabolic disorders. However, its role in the mesolimbic dopamine (DA) system, especially in the ventral tegmental area (VTA), needs to be elucidated. Here, we found that injection of Thiamet G, an O-GlcNAcase (OGA) inhibitor, in the VTA and nucleus accumbens (NAc) of mice, facilitated neuronal O-GlcNAcylation and decreased the operant response to sucrose as well as the latency to fall in rotarod test. Mice with DAergic neuron-specific knockout of O-GlcNAc transferase (OGT) displayed severe metabolic abnormalities and died within 4-8 weeks after birth. Furthermore, mice specifically overexpressing OGT in DAergic neurons in the VTA had learning defects in the operant response to sucrose, and impaired motor learning in the rotarod test. Instead, overexpression of OGT in GABAergic neurons in the VTA had no effect on these behaviors. These results suggest that protein O-GlcNAcylation of DAergic neurons in the VTA plays an important role in regulating the response to natural reward and motor learning in mice.

Abstract
Herein, in the presence of three structure-directing agents (SDAs), a family of imidazole-functionalized resorcin[4]arene-based coordination polymers (CPs), [Zn(TIC4R)(HCOO)]·HCOO·0.5DMF·1.5H2O (1), [Zn(TIC4R)(CN)]·HCOO·DMF·2.5H2O (2), and [Zn(TIC4R)(H2O)]·2HCOO·2H2O (3), were assembled under solvothermal conditions [TIC4R = tetra(imidazole) resorcin[4]arene]. 1 exhibits a double-layer structure with rectangle windows, and 2 and 3 display monolayer structures. The layers of CPs 2 and 3 are slides with different offsets along the a-axis. In addition, three CPs were used as catalysts to catalyze Knoevenagel condensations. Strikingly, all CPs exhibit remarkable catalytic performance for several substrates. To the best of our knowledge, this is the first time that a small organic acid as SDA was used in the syntheses of resorcin[4]arene-based supramolecular isomers.

Abstract
Macrophages undergo profound metabolic reprogramming to join key immunoregulatory functions, which can be initiated by pattern recognition receptors. TREM2 (triggering receptor expressed on myeloid cells 2), a macrophage phagocytic receptor, plays pivotal roles in sepsis by enhancing bacterial clearance, which is associated with regulation of reactive oxygen species (ROS) production. However, how intracellular ROS participate in TREM2-mediated bactericidal activity remains unclear. This study was designed to investigate the organelle source and biological activity of ROS in the context of TREM2-mediated immune defense during Escherichia coli infection. Bone marrow-derived macrophages (BMDMs) were transfected with TREM2-overexpressing adenoviruses or control viruses and challenged with E. coli. The BMDMs were administered to mouse models with local E. coli infection. In addition, monocytic TREM2 expression, NOX2 concentrations, and pyroptosis were detected in patients with bacterial sepsis. General ROS production was found to be comparable between TREM2-overexpressing and control BMDMs upon E. coli challenge. The deficiency of Nox2 led to impaired phagosome degradation and lack of bactericidal ability and abolished TREM2-mediated protective activity against pulmonary E. coli infection. Overexpression of TREM2 suppressed mitochondrial ROS generation, inhibited NLRP3/caspase-1 inflammasome activation, and finally protected BMDMs from gasdermin D-mediated pyroptosis during pulmonary E. coli infection. The protective role of TREM2 was further confirmed in mice with abdominal E. coli infection. Moreover, monocytic TREM2 expression was positively correlated with NOX2 concentrations and negatively correlated with pyroptosis and disease severity in patients with bacterial sepsis. Collectively, TREM2 controls macrophage immune functions by fine-tuning ROS generation and enhances the host defense against bacterial infection. Our data suggest that TREM2 is a promising candidate target for sepsis therapy.

Abstract
Objective: To explore the application value of artificial intelligence-assisted diagnosis system for TBS report in cervical cancer screening. Methods: A total of 16 317 clinical samples and related data of cervical liquid-based thin-layer cell smears, which were obtained from July 2020 to September 2020, were collected from Southern Hospital, Guangzhou Huayin Medical Inspection Center, Shenzhen Bao'an People's Hospital(Group) and Changsha Yuan'an Biotechnology Co., Ltd. The TBS report artificial intelligence-assisted diagnosis system of cervical liquid-based thin-layer cytology jointly developed by Southern Medical University and Guangzhou F. Q. PATHOTECH Co., Ltd. based on deep learning convolution neural network was used to diagnose all clinical samples. The sensitivity,specificity and accuracy of both artificial intelligence-assisted diagnosis system and cytologists using artificial intelligence-assisted diagnosis system were analyzed based on the evaluation standard(2014 TBS). The time spent by the two methods was also compared. Results: The sensitivity of artificial intelligence-assisted diagnosis system in predicting cervical intraepithelial lesions and other lesions (including endometrial cells detected in women over 45 years old and infectious lesions) under different production methods, different cytoplasmic staining and different scanning instruments was 92.90% and 83.55% respectively, and the specificity of negative samples was 87.02%, while that of cytologists using artificial intelligence-assisted diagnosis system was 99.34%, 97.79% and 99.10%, respectively. Moreover, cytologists using artificial intelligence-assisted diagnosis system could save about 6 times of reading time than manual. Conclusions: Artificial intelligence-assisted diagnosis system for TBS report of cervical liquid-based thin-layer cytology has the advantages of high sensitivity, high specificity and strong generalization. Cytologists can significantly improve the accuracy and work efficiency of reading smears by using artificial intelligence-assisted diagnosis system.

Abstract
MicroRNAs (miRNAs) play key roles in many physiologic and pathologic processes, including autophagy. Autophagy is cellular in an emergency response mechanism of environment stress, but their complex molecular regulatory mechanism under low-temperature stress is largely unknown in shrimp, especially miRNA-mediated regulation of autophagy in low-temperature tolerance. In this article, a shrimp PvTOR and miRNA pva-miR-151 cooperation in response to low-temperature stress has been reported. Pva-miR-151 showed expression patterns opposite to target PvTOR under low-temperature stress. The pva-miR-151 targets the 3'-UTR region of PvTOR, regulate the formation of autophagosome, which contribute to the degradation and recycling of damaged organelles. In addition, the low-temperature tolerance was correlated positively with autophagy in shrimp. Silenced pva-miR-151 increased sensitivity to low-temperature stress, whereas overexpression pva-miR-151 decreased the expression of PvTOR and p-TOR and increased tolerance to low-temperature stress by improving the formation of autophagosome and total hemocyte count. In addition, the TOR activator 3BDO can partially rescue autophagy induced by overexpression of pva-miR-151; these results indicate that miR-151 was necessary for the low-temperature tolerance in shrimp. Taken together, we provide a novel strategy and mechanism for shrimp breeding to improve shrimp low-temperature tolerance.

Abstract
BACKGROUND Constipation, mainly characterized by the difficulty in defecation, is a clinical symptom caused by a variety of factors. It can be manifested as normal or slow colonic transport abnormalities, which can occur alone or concurrently with defecation disorders. As there is not uniform definition and assessment standard, no clear plan could be used for the treatment of constipation. Although rhubarb, a traditional Chinese medicine, plays a therapeutic role in diseases involving constipation symptoms, the detailed mechanism of it in treating constipation remains unclear. METHODS A model of constipation-induced by diphenoxylate was prepared. Immunofluorescent staining was used to detect the expression of mucin 2 (MUC2), calnexin and chymase in colon. Western blotting was used to detect changes of tryptase and calnexin in the colon. And real-time polymerase chain reaction (PCR) was utilized to detect the changes of immunoglobulin-binding protein (Bip), X-box binding protein 1 (Xbp1) and C/EBP homologous protein (CHOP) of colonic goblet cells in mRNA levels. ELISA and biochemical kits were utilized to detect the changes of MUC2, Trefoil factor 3 (TFF3), acetylcholine, histamine and C-C motif chemokine ligand 5 (CCL5) in the colon. And the changes of colonic mucosa and intestinal flora of constipation model mice caused by rhubarb extract (RE) were analyzed to identify the mechanism of RE on the treatment of constipation. RESULTS RE promotes the secretion of colonic mucus by recruiting mast cells and enhancing the content of histamine and Ach in the mice colon. In the process, RE causes up-regulation of Bip and CHOP mRNA expression and down-regulation of Xbp1 and Xbp1s mRNA expression that induces ER stress of colonic epithelium associated with changes in the intestinal flora diversity and short-chain fatty acids content. CONCLUSION RE could relieve constipation by promoting the secretion of colonic mucus via mast cells activation and improving the intestinal microenvironment.

Abstract
Dendritic cells (DCs), including conventional DCs (cDCs) and plasmacytoid DCs (pDCs), serve as the sentinel cells of the immune system and are responsible for presenting antigen information. Moreover, the role of DCs derived from monocytes (moDCs) in the development of inflammation has been emphasized. Several studies have shown that the function of DCs can be influenced by gut microbes including gut bacteria and viruses. Abnormal changes/reactions in intestinal DCs are potentially associated with diseases such as inflammatory bowel disease (IBD) and intestinal tumors, allowing DCs to be a new target for the treatment of these diseases. In this review, we summarized the physiological functions of DCs in the intestinal micro-environment, their regulatory relationship with intestinal microorganisms and their regulatory mechanism in intestinal diseases.

Abstract
p70S6K is involved in cellular response, such as tumor metastases, the immune response and tissue repair in vertebrates. The role of p70S6K in these physiological processes in crustaceans remains, however, unknown. In this study, the Lvp70S6K was identified, containing a 5' UTR of 294 bp, an ORF of 1494 bp ad a 3' UTR of 211 bp, encoding 497 amino acids with a theoretical molecular weight of 70 kDa and an estimated isoelectric point of (pI) of 5.16. The multiple alignment found that Lvp70S6K was highly homologous with other invertebrates. Lvp70S6K mRNA was detected in all the tested tissues and the Lvp70S6K expression levels was significantly down-regulated and reached the lowest level (0.44-fold, p < 0.01) at 1.5 h after low temperature stress. The subcellular localization of Lvp70S6K could be detected in cytoplasm. ROS production was significantly up-regulation (1.19-fold, p < 0.01), total hemocyte count (THC) was significantly down-regulation (0.22-fold, p < 0.01), apoptosis rate was markedly increased (1.09-fold, p < 0.01), apoptosis-related genes of LvPDCD4 (1.61-fold, p < 0.01) and LvCyt.C (1.23-fold, p < 0.01) were up-regulated, and anti-apoptotic gene of LvBcl-2 (0.69-fold, p < 0.01), LvIAP1 (0.68-fold, p < 0.01) and LvIAP2 (0.45-fold, p < 0.01) were decreased after low temperature stress in hemolymph of Lvp70S6K-silenced shrimp at 1.5 h. Silencing of LvPTEN significantly increased Lvp70S6K, LvPI3K, LvAKT and LvmTOR expression. In summary, these results indicated that Lvp70S6K play a crucial role in oxidative and apoptosis, which was able to negatively regulate by PTEN.

Abstract
In the present study, the ability of baicalin to relieve neuropathic pain due to spinal nerve ligation in rats was explored, and the relationship between baicalin and α2-adrenoceptors (α2-AR) was determined. The neuropathic pain model was established by ligating the L5-L6 spinal nerves in Sprague-Dawley rats. Several α2-AR antagonists were injected into the intramedullary sheath to evaluate the role of baicalin in neuropathic pain. The antagonists included nonselective α2-AR antagonist idazoxan, α2a-AR antagonist BRL 44408, α2b-AR antagonist ARC 239 and α2c-AR antagonist JP 1302. The rats were divided into an untreated control group, saline group, baicalin group and baicalin + α2-AR antagonist groups. Paw withdrawal threshold (PWT) was tested to assess the level of pain felt by the rats. The levels of α2-AR mRNA were tested by reverse transcription-quantitative PCR. Inflammatory factors, including tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-17 and IL-1β, were analyzed by ELISA. The histopathological changes were assessed by hematoxylin and eosin staining. Flow cytometry was used to examine the percentage of CD4+ peripheral blood mononuclear cells (PBMCs). Compared with the saline group, the PWT value increased after treating with baicalin. However, intrathecal injection of α2-AR antagonist reversed the antinociceptive effects of baicalin. Compared with the saline group, the expression of α2a-AR and α2c-AR mRNA was upregulated significantly in the baicalin group (P<0.05). Levels of α2-AR mRNA were also decreased in the baicalin + idazoxan group compared with the baicalin group (P<0.05). The levels of TNF-α, IL-6, IL-17 and IL-1β were raised after treatment with baicalin. In addition, baicalin treatment ameliorated the histological damage in the spinal cord. The percentage of CD4+ PBMCs was increased in the saline group compared with the control group (P<0.05). Compared with the baicalin group, the percentage of CD4+ PBMCs was raised after treatment with the α2-AR antagonists. In conclusion, intrathecal injection of baicalin produced an antiallodynic effect in a spinal nerve ligation-induced neuropathic pain model. The mechanism may be related to the regulation of a2-AR expression.

Abstract
Background Making decisions in alignment techniques in total knee arthroplasty (TKA) remains controversial. This study aims to identify the potential patients who were suitable for the kinematic (KA) or mechanical alignment (MA). Methods We reviewed 296 consecutive patients (296 TKAs, including 114 KA-TKAs and 182 MA-TKAs) who underwent unilateral TKA using a computer-assisted navigation from 2016 to 2018 in our prospectively maintained database. The minimum followup was 1 year. Clinical outcomes including the range of motion (ROM) and knee society score (KSS) were compared between KA-TKAs and MA-TKAs. Multiple regression models were used to evaluate the relationship between alignment techniques and KSS at the 1-year followup. Interaction and stratified analyses were conducted according to gender, age, body mass index (BMI), preoperative hip-knee-ankle (HKA) angle, ROM and KSS. Results ROM and KSS at the 1-year followup didn’t differ between MA-TKAs and KA-TKAs (all p > 0.05). Alignment techniques did not associate with postoperative ROM (Adjusted β = 0.4, 95% confidence interval [CI]: − 0.3, 1.6; p = 0.752) or 1-year KSS (Adjusted β = 2.2, 95%CI: − 0.7, 5.6; p = 0.107). Patients with a BMI more than 30 kg/m^2 achieved better 1-year KSS when using MA than KA (p for interaction< 0.05). Additionally, patients with preoperative HKA angle more than 10 degrees varus benefited more from KA than MA (p for interaction< 0.05). Conclusions Patients with severe varus deformity may be suitable for the KA technique, whereas MA should be used in obese patients.

Abstract
This study aimed to investigate the protective effect of water extracts of Orychophragmus violaceus seeds on liver injury induced by thioacetamide(TAA) in mice. ICR male mice were randomly divided into seven groups: normal group, model group, bicyclol positive control group(200 mg·kg~(-1)), Kuihua Hugan Tablets group(350 mg·kg~(-1)), O. violaceus seeds low-dose water extract group(125 mg·kg~(-1)), middle-dose water extract group(250 mg·kg~(-1)), and high-dose water extract group(500 mg·kg~(-1)). Intragastric administration was given in all groups at 0.02 mL·g~(-1) body weight, 1 time a day for continuous 4 days. One h after the administration on the 4 th day, the liver injury model was induced by intraperitoneal injection of TAA(100 mg·kg~(-1)). The mice were put to death 24 hours later. Blood and tissues were taken and organ indexes were calculated. The activities of ALT, AST and TBiL in serum were detected. The content of MDA, GSH and the activity of SOD, GSH-Px in liver homogenate were examined by colorimetry method. HE staining was used to observe the pathological changes of liver tissues in mice. The protein expression levels of NF-κB p65, Keap-1, Nrf2, p-p38, p-JNK, p-ERK, Bax, Bcl-2, caspase-3, cleaved caspase-3 and caspase-8 were detected by Western blot. The results showed that as compared with the model group, various O. violaceus seeds groups could significantly improve the pathological conditions of liver and reduce ALT, AST, TBiL activities in serum of mice with liver injury. In the high-dose group, the activities of SOD, GSH-Px and the content of GSH were significantly increased, while MDA content was sharply declined. Meanwhile, O. violaceus seeds extract down-regulated the expressions of Bax, Keap-1, p-p38, p-JNK, p-ERK, NF-κB p65, cleaved caspase-3 and up-regulated the expressions of Nrf2, Bcl-2, caspase-3 and caspase-8. In conclusion, O. violaceus seeds extract exhibited potent protective effect on liver injury induced by TAA in mice, and its mechanism may be related to down-regulating levels of Keap-1, up-regulating the expressions of Nrf2, inhibiting the expressions of p-p38, p-ERK and NF-κB p65 signaling pathway, and inhibiting hepatocyte apoptosis by down-regulating the expressions of p-JNK and Bax and up-regulating the expressions of Bcl-2.

Abstract
Drugs of abuse leads to adaptive changes in the brain stress system, and produces negative affective states including aversion and anxiety after drug use is terminated. Corticotrophin-releasing hormone (CRH) is the main transmitter in control of response to stressors and is neuronal enriched in the central amygdala (CeA), a sub-region of the extended amygdala playing an important role in integrating emotional information and modulating stress response. The effect of CRH neurons in CeA on the negative emotions on morphine naïve and withdrawal mice is unclear. Thus, we utilized CRH-Cre transgenic mice injected with AAV-mediated Designer Receptors Exclusively Activated By Designer Drugs (DREADDs) to chemogenetically manipulate CRH neurons in CeA. And methods of behavior analysis, including conditioned place aversion (CPA), elevated plus maze and locomotor activity tests, were used to investigate morphine withdrawal-induced negative emotions in mice. The results showed that, inhibiting CRH neurons of CeA decreased the formation of morphine withdrawal-induced CPA, as well as the anxiety level of CRH-Cre mice. Furthermore, specifically activating CRH neurons in CeA evoked CPA and anxiety of morphine naïve mice. Neither inhibiting nor activating CRH neurons had effects on their locomotor activity. These results suggest that CRH neurons in CeA are involved in the mediation of morphine withdrawal-induced negative emotion in mice, providing a theoretical basis for drug addiction and relapse mechanism.

Abstract
OBJECTIVE To investigate the prevalence and risk factors of Blastocystis hominis infections among patients with HIV/AIDS in Fuyang City, Anhui Province. METHODS A cross-sectional study was conducted in Fuyang City, Anhui Province in 2016. The demographic and socioeconomic status, and the lifestyle and production style were collected using a questionnaire survey. B. hominis DNA was detected in subjects'stool samples using a PCR assay, and the CD4+ T lymphocyte count and HIV viral load were measured in the subjects' blood samples. The risk factors of B. hominis infections among patients with HIV/AIDS were identified using univariate and multivariate logistic regression analyses. RESULTS A total of 398 HIV/AIDS patients were enrolled in this study, with a mean age of 49.3 years, a mean body weight of 55.9 kg and a mean height of 164.4 cm. The prevalence of B. hominis infection was 6.78% in the study subjects, and no gender- (χ2 = 1.589, P = 0.207), education level- (χ2 =0.508, P = 0.776), marital status- (χ2 = 0.419, P = 0.811) or occupation-specific prevalence (χ2 = 2.744, P = 0.615) was detected. Among the patients with HIV/AIDS, there were no significant differences in the age (t = 0.370, P = 0.712), height (t = 1.587, P =0.113), body weight (t = 0.516, P = 0.606), CD4+ T lymphocyte count (t = 1.187, P = 0.230) or HIV viral load (t = 0.193, P =0.496) between B. hominis-infected and uninfected individuals. Dinking non-tap water [OR = 6.554, 95% CI: (1.876 to 22.903)] and keeping dogs [OR = 5.895, 95% CI: (2.017 to 17.225)] were identified as risk factors for B. hominis infection in patients with HIV/AIDS. CONCLUSIONS The prevalence of B. hominis infection is high in HIV/AIDS patients, and drinking non-tap water and keeping dogs are risk factors for B. hominis infection among HIV/AIDS patients.

Abstract
The enteric glia is an important component of the enteric nervous system and forms a broad network in the mucosa of the gastrointestinal tract. Enteric glial cells (EGC) are located in all layers of the intestinal wall and respond to neurotransmitters and neuromodulators through signal transduction pathways. The enteric nervous system interacts with resident glial cells in the gut, and there is increasing evidence that EGC are involved in the regulation of epithelial function. Epithelial cells have important absorption and secretion functions and are also involved in the formation of intestinal epithelial barrier. Studies have found that the enteric glia is not only involved in the regulation of gastrointestinal motility and epithelial barrier function, but also in the formation of cellular molecular bridges between intestinal neurons, enteroendocrine cells, immune cells, and epithelial cells. This article reviews the recent progress in the understanding of the role of EGC in the intestinal barrier and defense functions.

Abstract
This study focused on the fabrication and characterization of ammonium metatungstate hydrate (AMT) combined with cobalt(III) acetylacetonate (Co(acac)3)-loaded electrospun micro-nanofibers. The morphologies, structures, element distribution, through-pore size, and through-pore size distribution of AMT/Co(acac)3-loaded PAN/PS micro-nanofibers were investigated by a combination of field emission scanning electron microscopy (FESEM), flourier transformation infrared (FTIR) spectroscopy, energy disperse spectroscopy (EDS), through-pore size analyzer, and so on. These micro-nanofibers have many advantages in their potential application as electro-catalysts. The porous and large thorough-pore will benefit for effective electrolyte penetration, in addition to promoting gas bubbles evolving and releasing from catalyst surface timely.

Abstract
Psoriasis, a chronic inflammatory skin disorder disease, is closely associated with hyperproliferation of keratinocytes. Upregulated miR-223 has been found in peripheral blood mononuclear cells from patients with psoriasis and from psoriatic skin. However, its role in keratinocytes remains unknown. We thus aimed to investigate the function of miR-223 in psoriasis. Interleukin-22 (IL-22) is a crucial keratinocyte trigger in the T-cell-mediated immune response to psoriasis. We found miR-223 to be overexpressed in psoriatic lesions and in IL-22-stimulated HaCaT cells. HaCaT cells then were transfected with a miR-223 mimic or inhibitor to overexpress or inhibit expression of miR-223, respectively. A Cell Counting Kit-8 assay revealed that miR-223 overexpression promoted and miR-223 downregulation inhibited proliferation in IL-22-stimulated HaCaT cells. Flow cytometry analysis certified that miR-223 overexpression decreased HaCaT cell apoptosis, whereas miR-223 downregulation increased it. A dual-luciferase reporter assay demonstrated that miR-223 directly targeted the phosphatase and tensin homolog (PTEN) gene. MiR-223 also negatively regulated mRNA and protein expression of PTEN and modulated the PTEN/Akt pathway in IL-22-stimulated HaCaT cells. PTEN silencing attenuated the activity of the miR-223 inhibitor in these cells via the PTEN/Akt pathway. Overall, the results showed that miR-223 increased proliferation and inhibited apoptosis of IL-22-stimulated keratinocytes via the PTEN/Akt pathway.

Abstract
BACKGROUND Cancer associated fibroblasts (CAFs) are key stroma cells that play dominant roles in tumor progression. However, the CAFs-derived molecular determinants that regulate colorectal cancer (CRC) metastasis and chemoresistance have not been fully characterized. METHODS CAFs and NFs were obtained from fresh CRC and adjacent normal tissues. Exosomes were isolated from conditioned medium and serum of CRC patients using ultracentrifugation method and ExoQuick Exosome Precipitation Solution kit, and characterized by transmission electronic microscopy, nanosight and western blot. MicroRNA microarray was employed to identify differentially expressed miRNAs in exosomes secreted by CAFs or NFs. The internalization of exosomes, transfer of miR-92a-3p was observed by immunofluorescence. Boyden chamber migration and invasion, cell counting kit-8, flow cytometry, plate colony formation, sphere formation assays, tail vein injection and primary colon cancer liver metastasis assays were employed to explore the effect of NFs, CAFs and exosomes secreted by them on epithelial-mesenchymal transition, stemness, metastasis and chemotherapy resistance of CRC. Luciferase report assay, real-time qPCR, western blot, immunofluorescence, and immunohistochemistry staining were employed to explore the regulation of CRC metastasis and chemotherapy resistance by miR-92a-3p, FBXW7 and MOAP1. RESULTS CAFs promote the stemness, epithelial-mesenchymal transition (EMT), metastasis and chemotherapy resistance of CRC cells. Importantly, CAFs exert their roles by directly transferring exosomes to CRC cells, leading to a significant increase of miR-92a-3p level in CRC cells. Mechanically, increased expression of miR-92a-3p activates Wnt/β-catenin pathway and inhibits mitochondrial apoptosis by directly inhibiting FBXW7 and MOAP1, contributing to cell stemness, EMT, metastasis and 5-FU/L-OHP resistance in CRC. Clinically, miR-92a-3p expression is significantly increased in CRC tissues and negatively correlated with the levels of FBXW7 and MOAP1 in CRC specimens, and high expression of exosomal miR-92a-3p in serum was highly linked with metastasis and chemotherapy resistance in CRC patients. CONCLUSIONS CAFs secreted exosomes promote metastasis and chemotherapy resistance of CRC. Inhibiting exosomal miR-92a-3p provides an alternative modality for the prediction and treatment of metastasis and chemotherapy resistance in CRC.

Abstract
Objective: To observe the relationship between impaired myocardial untwisting and left ventricular diastolic dysfunction in patients with autoimmune diseases (AD). Methods: In this retrospective study, 95 AD patients (27 males, (38.6±14.2) years old) were enrolled as AD group and 71 gender and age matched healthy subjects (24 males, (37.6±12.2) years old) were enrolled as control group, all underwent transthoracic echocardiography and two-dimensional speckle-tracking echocardiography (STE) in our hospital between January 2014 and June 2018. Left ventricular untwisting and diastolic function parameters were measured. Multiple logistic regression analysis was used to identify related factors of left ventricular diastolic dysfunction in AD patients. Receiver operating characteristic (ROC) curve was used to identify the diagnosis value of untwisting parameters for left ventricular diastolic dysfunction in AD patients. Results: Compared with control group, left ventricular ejection fraction was lower (58(47, 66)% vs. 67 (62, 71) %, P<0.001), E/e' was higher (10.78 (7.28, 13.65) vs. 6.30 (5.55, 7.25) , P<0.001), isovolumic relaxation time was longer (73.5 (56.5, 88.0) ms vs. 62.0 (58.0, 68.5) ms, P<0.001),and untwist slope during isovolumic relaxation period (USIR) was lower (31.92 (14.09, 54.92) °/s vs. 59.90 (40.09, 87.18) °/s, P<0.001) in AD group than in control group. Multiple logistic regression analysis showed heart rate (OR=0.885, 95%CI 0.840-0.931, P<0.001), E/e' (OR=0.655, 95%CI 0.537-0.798, P<0.001) and USIR (OR=0.986, 95%CI 0.974-0.998, P=0.020) were independently related with left ventricular diastolic dysfunction in AD patients. ROC curve showed that area under the curve (AUC) was 0.919 (P<0.001), sensitivity was 87.6%, and specificity was 88.7%, when combining the heart rate, E/e', and USIR as assessment parameters for the diagnosis of left ventricular diastolic dysfunction in AD patients at a cutoff of 0.51. Conclusions: Impairment of myocardial untwisting indicates the presence of early stage left ventricular diastolic dysfunction in AD patients. USIR may be a sensitive parameter to evaluate early stage left ventricular diastolic dysfunction in AD patients.
