Abstract
Background Immune disorders and autoantibodies has been noted in both primary immune thrombocytopenia (ITP) and systemic lupus erythematosus (SLE). Whether the two disorders are correlated is unclear. The lack of evidence on the incidence of and risk factors for SLE in primary ITP patients poses a challenge for prediction in clinical practice. Therefore, we conducted this study. Methods The protocol was registered with PROSPERO (CRD42023403665). Web of Science, Cochrane, PubMed, and EMBASE were searched for articles published from inception to 30 September 2023 on patients who were first diagnosed with primary ITP and subsequently developed into SLE. Furthermore, the risk factors were analyzed. Study quality was estimated using the Newcastle-Ottawa Scale. The statistical process was implemented using the R language. Results This systematic review included eight articles. The incidence of SLE during the follow-up after ITP diagnosis was 2.7% (95% CI [1.3-4.4%]), with an incidence of 4.6% (95% CI [1.6-8.6%]) in females and 0 (95% CI [0.00-0.4%]) in males. Older age (OR = 6.31; 95% CI [1.11-34.91]), positive antinuclear antibody (ANA) (OR = 6.64; 95% CI [1.40-31.50]), hypocomplementemia (OR = 8.33; 95% CI [1.62-42.91]), chronic ITP (OR = 24.67; 95% CI [3.14-100.00]), organ bleeding (OR = 13.67; 95% CI [2.44-76.69]), and female (OR = 20.50; 95% CI [4.94-84.90]) were risk factors for subsequent SLE in ITP patients. Conclusion Patients with primary ITP are at higher risk of SLE. Specific follow-up and prevention strategies should be tailored especially for older females with positive ANA, hypocomplementemia, or chronic ITP. In subsequent studies, we need to further investigate the risk factors and try to construct corresponding risk prediction models to develop specific prediction strategies for SLE.

Abstract
The present work aimed to explore the role of long non-coding RNA (lncRNA)-AC020978 in postoperative cognitive disorder (POCD) and the underlying mechanism. The POCD mouse model was constructed through isoflurane anesthesia + abbreviated laparotomy. The AC020978 expression in brain tissue was silenced after lentivirus injection, then Morris water maze test was conducted to detect the cognitive disorder level, flow cytometry was performed to analyze M1 macrophage level, ELISA was carried out to measure inflammatory factor levels, H&E, Nissl and immunohistochemical staining was performed to detect the pathological changes in brain tissue, and Western blotting assay was adopted to detect protein expression. In addition, microglial cells were cultured in vitro, after lentivirus infection, the effect of AC020978 on the M1 polarization of microglial cells and glycolysis was observed. AC020978 overexpression promoted POCD progression and aggravated cognitive disorder in mice; in addition, the proportion of peripheral and central M1 cells increased, the inflammatory factor levels were upregulated, and microglial cells were activated. By contrast, AC020978 silencing led to cognitive disorder in mice and suppressed microglial cell activation and M1 polarization. In vitro experimental results indicated that AC020978 promoted the expression and phosphorylation of PKM2, which promoted inflammatory response through enhancing microglial cell glycolysis and M1 polarization. AC020978 interacts with PKM2 to promote the glycolysis and M1 polarization of microglial cells, thus regulating cognitive disorder and central inflammation in POCD.

Abstract
AIM We investigated the effects and target of gastrodin (GAS) for treating depression through network pharmacology combined with experimentation. METHODS The therapeutic target and signal of GAS for depression were analyzed by network pharmacology. Depression in mice was mimicked with a chronic unpredictable mouse stress (CUMS) model. Through open field, elevated plus maze, forced swimming, and tail suspension tests, the effects of GAS on the CUMS mice behaviors were examined, and the levels of neurotransmitters were detected. The histopathological changes were assayed by H&E and IHC staining, and the protein expressions were detected by Western blotting. Small molecule-protein docking and molecular dynamics experiments were conducted to simulate the binding mode between GAS and Caspase-3. RESULTS Network pharmacological analysis revealed that Caspase-3 was the action target of GAS. GAS could improve depression-like behaviors in CUMS mice, elevate their neurotransmitter levels, ameliorate their nerve cell injury, and inhibit their Caspase-3 expression. After knocking out Caspase-3, the effects of GAS were inhibited. Molecular dynamics simulation and small molecule-protein docking found that GAS bound to Caspase-3 at SER25, inhibiting the maturation and activation of Caspase-3. CONCLUSION We find that GAS can act as a Caspase-3 inhibitor, which improves depression-like behaviors and nerve cell injury in CUMS mice by inhibiting Caspase-3-mediated apoptosis.

Abstract
We focused on investigating the effects and mechanisms of polystyrene (PS) microplastics in Alzheimer's disease (AD). PS could promote the cognitive impairment in mice and antagonize the action of PS. Meanwhile, it could promote microglial pyroptosis and aggravate neuroinflammation. In vitro results also showed that PS induced pyroptosis of BV2 and RAW264.7, after GSDMD silencing, such pyroptosis was inhibited. Our study found that PS aggravated neuroinflammation by inducing microglial pyroptosis, thereby promoting the progression of cognitive impairment in AD. This finding offers new support and reference for the induction of AD progression by environmental factors.

Abstract
Background peripheral neuroblastic tumors (pNT) have high incidence and mortality, and infants are prone to various infectious diseases. The purpose of this study is to understand the immunization status of children with pNT in the real-world and the incidence of adverse reactions after vaccination, and to evaluate the feasibility of vaccination and the influencing factors of vaccination. Methods Children with pNT treated in the Children's Hospital Affiliated to Zhejiang University from January 1, 2011 to December 1, 2021 were included. By referring to medical records, the vaccination history of the national immunization program (NIP) vaccines and the occurrence of adverse events following immunization(AEFI), current status and safety of immunization in children with pNT in the real-world were analyzed. Results Among 784 children with pNT, 394 were able to obtain the history of vaccination. The overall vaccination rate of NIP vaccines was 71.49% before chemotherapy and 37.67% after chemotherapy, and the recovery time of vaccination after treatment was 16.00 (6.00,24.00) months. Age, time of tumor diagnosis and disease classification were significantly correlated with vaccination. AEFI reported an incidence of 0.23‰. Conclusion The vaccination rate of children with pNT is generally low, especially the vaccination rate after chemotherapy. The vaccination safety is good, children should be encouraged to immunize.

Abstract
OBJECTIVES The global prevalence of osteoporosis is rising, yet it is unclear whether people with osteoporosis have a higher risk of depression than those without osteoporosis. STUDY DESIGN A cross-sectional study. METHODS We used nationally representative data from the US National Health and Nutrition Examination Survey (NHANES) in 2005-2006, 2007-2008, 2009-2010, 2013-2014, and 2017-2020. The diagnosis of osteoporosis was based on the bone mineral density of the femoral neck measured by dual-energy X-ray absorptiometry. Depression was assessed by the Patient Health Questionnaire-9 (PHQ-9), with a score ≥5 as depressive symptoms and a score ≥10 as probable depression. We used logistic regression models to evaluate the association between osteoporosis and depressive symptoms and probable depression. RESULTS We included 11,603 adults (aged 50 years and older, 52.3% male) and observed 5.2% of them had osteoporosis. 31.9% of these osteoporotic people had depressive symptoms, and 10.0% had probable depression. Compared to participants without osteoporosis, those with osteoporosis were 1.73 times more likely to experience depressive symptoms (odds ratio [OR] = 1.73, 95% confidence interval [CI] 1.20-2.50) and 1.91 times more likely to experience probable depression (OR = 1.91, 95% CI 1.02-3.59), after adjusting for sex, age, race/ethnicity, education, marital status, family income, body mass index, smoking, physical activity, and alcohol abuse. Moderate-to-vigorous activities mediated the associations between osteoporosis and depression and depressive symptoms. CONCLUSIONS Osteoporosis is an independent risk factor for depression. This study highlights the need to evaluate the mental well-being of patients with osteoporosis in clinical and primary health care.

Abstract
To explore the antidepressant effects and targets of atractylenolide I (ATR) through a network pharmacological approach. Relevant targets of ATR and depression analyzed by network pharmacology were scored (identifying 5-HT2A targets). Through elevated plus maze, open field, tail suspension, and forced swimming tests, the behavioral changes of mice with depression (chronic unpredictable mild stress [CUMS]) were examined, and the levels of neurotransmitters including serotonin, dopamine, and norepinephrine (5-HT, DA, and NE) were determined. The binding of ATR to 5-HT2A was verified by small molecular-protein docking. ATR improved the behaviors of CUMS mice, elevated their levels of neurotransmitters 5-HT, DA, and NE, and exerted a protective effect on their nerve cell injury. After 5-HT2A knockout, ATR failed to further improve the CUMS behaviors. According to the results of small molecular-protein docking and network pharmacological analysis, ATR acted as an inhibitor by binding to 5-HT2A. ATR can improve the behaviors and modulate the neurotransmitters of CUMS mice by targeting 5-HT2A.

Abstract
While the prognostic role of immunoglobulin heavy chain locus (IGH) rearrangement in minimal residual disease (MRD) in pediatric B-acute lymphoblastic leukemia (B-ALL) has been reported, the contribution of light chain loci (IGK/IGL) remains elusive. This study is to evaluate the prognosis of IGH and IGK/IGL rearrangement-based MRD detected by next-generation sequencing in B-ALL at the end of induction (EOI) and end of consolidation (EOC). IGK/IGL rearrangements identify 5.5% of patients without trackable IGH clones. Concordance rates for IGH and IGK/IGL are 79.9% (cutoff 0.01%) at EOI and 81.0% (cutoff 0.0001%) at EOC, respectively. Patients with NGS-MRD < 0.01% at EOI or <0.0001% at EOC present excellent outcome, with 3-year event-free survival rates higher than 95%. IGH-MRD is prognostic at EOI/EOC, while IGK-MRD at EOI/EOC and IGL-MRD at EOI are not. At EOI, NGS identifies 26.2% of higher risk patients whose MRD < 0.01% by flow cytometry. However, analyzing IGK/IGL along with IGH fails to identify additional higher risk patients both at EOI and at EOC. In conclusion, IGH is crucial for MRD monitoring while IGK and IGL have relatively limited value.

Abstract
AIM We investigated the mechanism, whereby tumor necrosis factor-like ligand 1A (TL1A) mediates the A1 differentiation of astrocytes in postoperative cognitive dysfunction (POCD). METHODS The cognitive and behavioral abilities of mice were assessed by Morris water maze and open field tests, while the levels of key A1 and A2 astrocyte factors were detected by RT-qPCR. Immunohistochemical (IHC) staining was used to examine the expression of GFAP, western blot was used to assay the levels of related proteins, and enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory cytokines. RESULTS The results showed that TL1A could promote the progression of cognitive dysfunction in mice. Astrocytes differentiated into A1 phenotype, while unobvious changes were noted in astrocyte A2 biomarkers. Knockout of NLRP3 or intervention with NLRP3 inhibitor could inhibit the effect of TL1A, improving the cognitive dysfunction and suppressing the A1 differentiation. CONCLUSION Our results demonstrate that TL1A plays an important role in POCD in mice, which promotes the A1 differentiation of astrocytes through NLRP3, thereby exacerbating the progression of cognitive dysfunction.

Abstract
AIM We investigated the effect and mechanism of Icariin (ICA) on improving neurobehavioral ability of mice with Alzheimer's disease (AD). METHODS We selected 10-month-old APP/PS1 mice (AD) and wild-type C57BL/6J mice (Normal). After intragastric administration of ICA, Morris water maze was employed to detect neurobehavioral improvements, and to assay key ferroptosis indicators and oxidative stress levels. The common target of ICA for resisting ferroptosis and AD was predicted by network pharmacology. RESULTS ICA could improve the neurobehavioral, memory and motor abilities of AD mice. It could lower the ferroptosis level and enhance the resistance to oxidative stress. After inhibition of MDM2, ICA could no longer improve the cognitive ability of AD mice, nor could it further inhibit ferroptosis. Network pharmacological analysis revealed that MDM2 might be the target of ICA action. CONCLUSIONS We found that ICA can inhibit ferroptosis of nerve cells, thereby ameliorating neural damage in mice with AD.

Abstract
PURPOSE/OBJECTIVE(S) The optimization of energy layer distributions is crucial for efficient proton ARC therapy: on one hand, a sufficient number of energy layers is needed to ensure the plan quality; on the other hand, an excess number of energy jumps can substantially slow down the treatment delivery. This work will develop a new treatment plan optimization method with direct minimization of number of energy jumps (NEJ), which will be shown to outperform state-of-the-art methods in both plan quality and delivery efficiency. MATERIALS/METHODS The proposed method jointly optimizes the plan quality and minimizes the NEJ. To minimize NEJ, (1) the proton spots x is summed per energy layer to form the energy vector y; (2) y is binarized via sigmoid transform into y1; (3) y1 is multiplied with a predefined energy order vector via dot product into y2; (4) y2 is filtered through the finite-differencing kernel into y3 in order to identify NEJ; (5) only the NEJ of y3 is penalized, while x is optimized for plan quality. The solution algorithm to this new method is based on iterative convex relaxation. RESULTS The new method is validated in comparison with state-of-the-art methods called energy sequencing (ES) method and energy matrix (EM) method. In terms of delivery efficiency, the new method had fewer NEJ, less energy switching time, and generally less total delivery time. In terms of plan quality, the new method had smaller optimization objective values, lower normal tissue dose, and generally better target coverage. A head-and-neck case is provided in the table with the following dosimetric parameters: planning objective value F; conformity index CI; homogeneity index HI; mean dose of larynx DOAR; mean body dose Dbody; the unit of dose is Gy. CONCLUSION We have developed a new treatment plan optimization method with direct minimization of NEJ, and demonstrated that this new method outperformed state-of-the-art methods (ES and EM) in both plan quality and delivery efficiency.

Abstract
Aim of this research was to examine the impact of paeoniflorin (Pae) in suppressing the occurrence of ferroptosis in individuals with Alzheimer's disease (AD). The study utilized APP/PS1 mice with AD as the experimental subjects. Following the administration of Pae, the cognitive behaviors of mice were evaluated and the key indexes of ferroptosis were measured, as well as levels of oxidative stress (OS). For in-vitro experiments, Erastin was adopted for inducing the ferroptosis of PC12 cells, and the level of cell ferroptosis was detected after Pae treatment. Pae improved the cognitive ability of AD mice, reduced the level of ferroptosis, decreased the iron ion and MAD levels in brain tissues, and increased SOD expression. In PC12 cells, Pae suppressed the Erastin-induced ferroptosis, mitigated oxidative damage, and reduced the level of ROS. Based on the findings from our research, it was observed that Pae exhibited a specific binding affinity to P53, leading to the suppression of ferroptosis. This mechanism ultimately resulted in the improvement of nerve injury in mice with AD.

Abstract
Intracranial Rosai-Dorfman disease (RDD) is a rare, self-limiting histiocytic disease of unknown etiology. Extranodal marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) is also rare and intracranial RDD complicated by MALT lymphoma is even rarer. The present study reports a case of a 55-year-old female who was admitted to The Second Affiliated Hospital of Jiaxing University (Jiaxing, China) with headache for half a month and ptosis of the right eyelid for 4 days. Computerised tomography and magnetic resonance imaging revealed a right parasellar tumor and, subsequently, subtotal resection of the tumor was performed. Postoperative pathology revealed intracranial RDD complicated by MALT lymphoma. The patient received chemotherapy after surgery and achieved good therapeutic effects. After 12 months of follow-up, the residual tumor disappeared and the ptosis prominently improved. To the to the best of the authors' knowledge, the present case is the first reported case of an adult intracranial RDD complicated by MALT lymphoma.

Abstract
Objective: To analyze the distribution characteristics of plasma renin concentration (PRC) in patients with aldosterone-producing adenoma (APA) and its impact on diagnosis. Methods: In this retrospective case series, clinical data from 200 patients with APA (80 men and 120 women; mean age 45.6 years) in the First Affiliated Hospital of Chongqing Medical University from November 2013 to January 2022 were evaluated. PRC was determined by automated chemiluminescence immunoassay. The distribution characteristics of PRC were analyzed, and 8.2 mU/L was used as the low renin cutoff to evaluate whether renin was suppressed. Results: The median PRC was 1.6 mU/L (range, 0.4-41.5 mU/L). There were 116 patients with APA with PRC of ≤2 mU/L, 41 patients with 2<PRC≤4 mU/L. PRC was not suppressed (PRC>8.2 mU/L) in 8.0% (16/200) of the patients with APA. And PRC was not suppressed in 2.5% (5/200) of the patients with APA, resulting in a primary aldosteronism negative screening outcome. Conclusions: Although most patients with APA have low PRC, there are a small number (8%) of patients whose PRC has not been fully suppressed, which can lead to missed diagnoses during primary aldosteronism screening. While primary aldosteronism is highly suspected, further investigations are required to determine the diagnosis, even if PRC is not fully suppressed at screening.

Abstract
Objective: To establish and validate a nomogram-based predictive model for idiopathic hyperaldosteronism (IHA). Methods: This cross-sectional study was conducted with the collected clinical and biochemical data of patients with primary aldosteronism (PA) including 249 patients with unilateral primary aldosteronism (UPA) and 107 patients with IHA, who were treated at the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to November 2022. Plasma aldosterone concentration (PAC) and plasma renin concentration (PRC) were measured by chemiluminescence. Stepwise regression analysis was applied to select the key predictors of IHA, and a nomogram-based scoring model was developed. The model was validated in another external independent cohort of patients with PA including 62 patients with UPA and 43 patients with IHA, who were diagnosed at the Department of Endocrinology, First Affiliated Hospital of Zhengzhou University. An independent-sample t test, Mann-Whitney U test, and χ2 test were used for statistical analysis. Results: In the training cohort, in comparison with the UPA group, the IHA group showed a higher serum potassium level [M(Q1, Q3), 3.4 (3.1, 3.8) mmol/L vs. 2.7 (2.1, 3.1) mmol/L] and higher PRC [4.0 (2.1, 8.2) mU/L vs. 1.5 (0.6, 3.4) mU/L] and a lower PAC post-saline infusion test (SIT) [305 (222, 416) pmol/L vs. 720 (443, 1 136) pmol/L] and a lower rate of unilateral adrenal nodules [33.6% (36/107) vs. 81.1% (202/249)]; the intergroup differences in these measurements were statistically significant (all P<0.001). Serum potassium level, PRC, PAC post-SIT, and the rate of unilateral adrenal nodules showed similar performance in the IHA group in the validation cohort. After stepwise regression analysis for all significant variables in the training cohort, a scoring model based on a nomogram was constructed, and the predictive parameters included the rate of unilateral adrenal nodules, serum potassium concentration, PAC post-SIT, and PRC in the standing position. When the total score was ≥14, the model showed a sensitivity of 0.65 and specificity of 0.90 in the training cohort and a sensitivity of 0.56 and specificity of 1.00 in the validation cohort. Conclusion: The nomogram was used to successfully develop a model for prediction of IHA that could facilitate selection of patients with IHA who required medication directly.

Abstract
Mycoplasma hyorhinis (M. hyorhinis) is a commensal of the upper respiratory tract in swine with the typical clinical presentations of arthritis and polyserositis in postweaning pigs. However, it has also been associated with conjunctivitis and otitis media, and recently has been isolated from meningeal swabs and/or cerebrospinal fluid of piglets with neurological signs. The objective of this study is to evaluate the role of M. hyorhinis as a potential pathogen associated with neurological clinical signs and central nervous system lesions in pigs. The presence of M. hyorhinis was evaluated in a clinical outbreak and a six-year retrospective study by qPCR detection, bacteriological culture, in situ hybridization (RNAscope®), and phylogenetic analysis and with immunohistochemistry characterization of the inflammatory response associated with its infection. M. hyorhinis was confirmed by bacteriological culture and within central nervous system lesions by in situ hybridization on animals with neurological signs during the clinical outbreak. The isolates from the brain had close genetic similarities from those previously reported and isolated from eye, lung, or fibrin. Nevertheless, the retrospective study confirmed by qPCR the presence of M. hyorhinis in 9.9% of cases reported with neurological clinical signs and histological lesions of encephalitis or meningoencephalitis of unknown etiology. M. hyorhinis mRNA was confirmed within cerebrum, cerebellum, and choroid plexus lesions by in situ hybridization (RNAscope®) with a positive rate of 72.7%. Here we present strong evidence that M. hyorhinis should be included as a differential etiology in pigs with neurological signs and central nervous system inflammatory lesions.

Abstract
OBJECTIVE To identify and verify the interacting protein of α-11 giardin, so as provide the experimental evidence for studies on the α-11 giardin function. METHODS The yeast two-hybrid cDNA library of the Giardia lambia C2 strain and the bait plasmid of α-11 giardin were constructed. All proteins interacting with α-11 giardin were screened using the yeast two-hybrid system. α-11 giardin and all screened potential interacting protein genes were constructed into pBiFc-Vc-155 and pBiFc-Vn-173 plasmids, and co-transfected into the breast cancer cell line MDA-MB-231. The interactions between α-11 giardin and interacting proteins were verified using bimolecular fluorescence complementation (BiFC). RESULTS The yeast two-hybrid G. lambia cDNA library which was quantified at 2.715 × 107 colony-forming units (CFU) and the bait plasmid containing α-11 giardin gene without an autoactivation activity were constructed. Following two-round positive screening with the yeast two-hybrid system, two potential proteins interacting with α-11 giardin were screened, including eukaryotic translation initiation factor 5A (EIF5A), calmodulin-dependent protein kinase (CAMKL) and nicotinamide adenine dinucleotide phosphate-specific glutamate dehydrogenase (NADP-GDH), hypothetical protein 1 (GL50803_95880), hypothetical protein 2 (GL50803_87261) and a protein from Giardia canis virus. The α-11 giardin and EIF5A genes were transfected into the pBiFc-Vc-155 and pBiFc-Vn-173 plasmids using BiFC, and the recombinant plasmids pBiFc-Vc-155-α-11 and pBiFc-Vn-173-EIF5A were co-tranfected into MDA-MB-231 cells, which displayed green fluorescence under a microscope, indicating the interaction between α-11 giardin and EIF5A protein in cells. CONCLUSIONS The yeast two-hybrid cDNA library of the G. lambia C2 strain has been successfully constructed, and six potential protein interacting with α-11 giardin have been identified, including EIF5A that interacts with α-11 giardin in cells.

Abstract
BACKGROUND There is a high incidence and mortality rate in children with hematologic tumors (CHT), who are more prone to various infectious diseases. This study aims to clarify the real-world National Immunization Program (NIP) vaccination status of CHT before and after chemotherapy. METHODS Medical records, NIP vaccination data, and the Adverse Event Following Immunization (AEFI) of CHT who were admitted to the Children's Hospital, Zhejiang University School of Medicine from January 1, 2011 to December 1, 2021 were completely collected. RESULTS Total of 2,874 CHT were included and 1975 (68.7%) had vaccination records. Among the enrolled patients, the vaccination rate of all NIP vaccines was lower than 90% before diagnosis. Only 24.29% of CHT (410/1688) resumed vaccination after chemotherapy, and 69.02% (283/410) resumed vaccination more than 12 months after chemotherapy. No uncommon or serious side effects were reported. CONCLUSION The vaccination rate of CHT after chemotherapy was lower than that before the disease was diagnosed. It is necessary to provide more evidence-based support and formulate specific regimens to perfect the vaccination procedure after chemotherapy, so as to improve the quality of life of CHT.

Abstract
This work mainly aimed to explore the role and mechanism of advanced glycation end-products (AGEs) in inducing cerebrovascular endothelial cell pyroptosis under oxygen glucose deprivation (OGD) condition. The mouse cerebral microvascular endothelial cells (BMECs and bEnd.3) were used as the objects to construct the OGD model in vitro. Then, cells were pretreated with AGE-modified human serum albumin (AGE-HSA). Thereafter, CCK-8 assay was conducted to detect cell viability, and flow cytometry (FCM) was performed to measure cell pyroptosis level. Meanwhile, the expression of inflammatory factors was detected by enzyme-linked immunosorbent assay (ELISA). The expression of HIF-α, NLRP3, and RAGE was detected by fluorescence staining. The opening status of cell membrane pore was observed under the electron microscope, and the expression levels of FL-GSDMD, NT-GSDMD, and caspase-1 were measured through Western Blot (WB) assay. Moreover, bEnd.3 cells were treated with siRAN-silenced NLRP3 and HIF-α inhibitor, so as to observe the effect of AGEs on cell pyroptosis level. In the mouse model, the middle cerebral artery occlusion (MCAO) model was constructed by the suture-occluded method. After intraperitoneal injection of AGEs, the pathological changes in mouse brain tissues were detected; the expression levels of NLRP3, ZO-1, and CD31 were determined by histochemical staining, and the levels of inflammatory factors and pyroptosis-related proteins were also detected. Under OGD condition, AGEs induced the pyroptosis of bEnd.3 cells, and the cell pyroptosis rate increased, higher than that of the OGD group. Meanwhile, the levels of inflammatory factors were up-regulated; the expression of HIF-α, NLRP3, and RAGE in cells increased; and the levels of NT-GSDMD and caspase-1 were markedly higher than those of the control and OGD groups. siRNA-NLRP3 or HIF-α inhibitor treatment suppressed pyroptosis and reduced the inflammatory factor levels. In mouse experiments, AGE injection aggravated brain injury in the MCAO mouse model, decreased the expression of ZO-1 and CD31, and elevated the levels of NLRP3 and inflammatory factors. Under cerebral ischemia condition, AGEs can induce endothelial cell pyroptosis via HIF-α-RAGE-NLRP3, thereby further aggravating brain injury.

Abstract
AIM We aimed to explored the role of Antcin K in resisting depression and its targets. METHODS LPS/IFN-γwas used to induce the activation of microglial BV2 cells. Following Antcin K pretreatment, the proportion of M1 cells was determined using flow cytometry (FCM), the expression of cytokines was measured through ELISA, and that of CDb and NLRP3 was analyzed by cell fluorescence staining. The protein levels were detected by Western-blot assay. After NLRP3 was knocked down in BV2 cells (BV2-nlrp3-/-), the M1 polarization level was detected with Antcin K treatment. The targeted binding relation of Antcin K with NLRP3 was confirmed through small molecule-protein docking and co-immunoprecipitation assay. The chronic unpredictable stress model (CUMS) was constructed to mimic the depression mice. After the administration of Antcin K, the neurological behavior of CUMS mice were detected by open-field test (OFT), elevated plus maze, forced swimming test (FST), and tail suspension test (TST). In addition, the expression of CD11b and IBA-1 was detected through histochemical staining, and the tissue pathological changes were detected by H&E staining. RESULTS Antcin K suppressed the M1 polarization of BV2 cells and reduced the expression of inflammatory factors. Meanwhile, NLRP3 exhibited targeted binding relation with Antcin K, and Antcin K lost its effect after NLRP3 knockdown. In the CUMS mouse model, Antcin K improved the depression status and neurological behaviors in mice, and decreased central neuroinflammation and microglial cell polarization. CONCLUSION Antcin K targets NLRP3 to suppress microglial cell polarization, alleviate central inflammation in mice and improve their neurological behaviors.

Abstract
AIM This study was aimed at exploring the mechanism by which aurantiamide (Aur) targeted NLRP3 to suppress microglial cell polarization. METHODS The 7-month-old APP/PS1 mice and C57BL/6 mice were applied to be the study objects, and Aur was administered intragastrically to APP/PS1 mice at 10 mg/kg and 20 mg/kg. The changes in the neurocognitive function of mice were measured by Morris Water Maze (MWM) test. In the in vitro experiments, the mouse BV2 cells were employed as the study objects, which were subject to treatment with 10 μM and 20 μM Aur and induced with LPS and IFN-γ in order to activate BV2 cells and induce their M1 polarization. RESULTS Aur was found to suppress the M1 polarization of mouse microglia, reduce central neuroinflammation, and improve the cognitive function in mice. Meanwhile, Aur suppressed the activation and the expression of NLRP3 inflammasome. The results of experiments in vitro demonstrated that Aur inhibited the activation and M1 polarization of BV2 cells. CONCLUSION Aur targets NLRP3 and suppresses the activation of NLRP3 inflammasome.

Abstract
Background Creeping fat, a form of visceral adipose tissue (VAT) that wraps the intestinal wall, influences the formation of Crohn’s disease (CD) strictures. The degree of fat wrapping from intestinal stricture resections is correlated with the extent of chronic inflammation, fibrosis, stricture formation, and response to biologic therapy. VAT and subcutaneous adipose tissue (SAT) ratios from CTE (computed tomography) scans are elevated in CD strictures. However, the definition of strictures in these studies has been poorly defined and not included current well-recognized criteria: 1) bowel wall thickness (BWT), 2) narrowed luminal diameter, and 3) pre-stenotic dilation. (PSD). Purpose The objective of this pilot study was to assess the relationship of 2D and 3D VAT:SAT ratios with CT stricture parameters in patients with terminal ileal (TI) CD strictures. Method 2D VAT:SAT ratios from CT’s of CD patients with TI strictures defined as increased BWT, narrowed luminal diameter (< 50% relative to normal adjacent distended loop), and PSD greater than the stricture diameter were retrospectively obtained from a database and chart review. CT’s from fibrostenotic CD patients were sex and BMI matched to patients with only TI inflammatory behaviour. Patient demographics, medication, smoking, and surgical history were also obtained. Analyses were adjusted for age, sex, and BMI covariates. Unpaired t-tests and multi-variable logistic regression analyses were conducted. Result(s) Twenty-eight patients with stricturing CD had a significantly greater mean VAT:SAT volume ratio than 29 non-stricturing CD (41.5 cm3 vs 34.2 cm3, p=0.03). Thirty-six percent (10/28) of CD stricture patients had prior ileocolic resection with a mean disease duration of 13.5 years (range 0-48). The median ileal BWT (7.0 mm, range 4.0-13.0 mm) for the stricturing group was significantly greater than those with inflammatory behaviour (BWT 2.0 mm, p<0.0001). The median luminal diameter and PSD for the stricture group was 2.0 mm (range 0 - 14.0 mm), and 3.0 cm (range 1.0 - 7.3 cm), respectively. Image ![]()
Conclusion(s) Fibrostenotic TI CD patients have increased VAT:SAT ratios in comparison to those with only inflammatory behaviour. These pilot VAT:SAT results provide an initial foundation for further studies to assess its predictive role in responsiveness of medical or surgical therapies in stricturing CD.

Abstract
Elderly individuals are often affected by osteoporosis and have poor stability after fracture reduction. Moreover, there is still controversy regarding the clinical effects of the treatment for unstable intertrochanteric fractures in the elderly. The Cochrane, Embase, PubMed, and other databases were searched, and a meta-analysis of the literature on the treatment of unstable intertrochanteric fractures of the elderly with InterTan, PFNA, and PFNA-II was conducted. Seven studies were screened, with a total of 1236 patients. Our meta-analysis results show that InterTan is not significantly different from PFNA in terms of operation and fluoroscopy times, but it takes longer than PFNA-II. In terms of postoperative screw cut, pain, femoral shaft fracture, and secondary operations, InterTan is superior to PFNA and PFNA-II. Conversely, in terms of intraoperative blood loss, hospital stay, and postoperative Harris score, there is no significant difference between InterTan and PFNA and PFNA-II. Compared to PFNA and PFNA-II, InterTan internal fixation has advantages in the treatment of unstable intertrochanteric fractures in elderly individuals in terms of screw cutting, femoral shaft fractures, and secondary operations. However, InterTan operation and fluoroscopy times take longer than PFNA and PFNA-II.

Abstract
Background Compared with the current commonly used pretreatment approaches, the therapeutic effect of contrast-enhanced ultrasound-guided sclerotherapy with lauromacrogol injection (CEUSL) on cesarean scar pregnancy (CSP) is not clear. This study aimed to investigate the clinical efficacy and safety of CEUSL compared with gelatin sponge uterine artery embolization (UAE) and UAE combined with methotrexate (UAEM) in the pretreatment of CSP to prevent massive bleeding during subsequent curettage. Methods Sixty-four patients were divided into the CEUSL (n=20), UAE (n=22), and UAEM (n=22) groups. All patients with CSP underwent curettage and hysteroscopy after CEUSL, UAE, or UAEM pretreatment. The efficacy and safety indicators after pretreatment were analyzed. Results Time for pretreatment [95% confidence interval (CI): 31.92-39.28] and hospitalization cost (95% CI: 7,852.32-9,063.23) were significantly decreased in the CEUSL group compared with that in the UAE (95% CI: 53.55-59.99% and 95% CI: 12,901.42-15,166.63, respectively) and the UAEM group (95% CI: 52.90-58.83 and 95% CI: 11,324.66-13,302.69, respectively; P<0.001). The beta human chorionic gonadotropin (β-hCG) percentage decrease 24 hours later and the hospital stay were significantly decreased in the CEUSL group (95% CI: 0.65-0.70 and 95% CI: 3.32-4.58 days, respectively) compared with those in the UAE (95% CI: 0.67-0.74 and 95% CI: 4.06-5.84, respectively) or UAEM (95% CI: 0.62-0.68 and 95% CI: 4.12-5.88, respectively) groups (P<0.05). After pretreatment, there were significantly fewer patients (P<0.05) with fever (95% CI: -0.52 to -0.093), pelvic pain (95% CI: -0.427 to -0.018), increased white blood cell count (95% CI: -0.359 to 0.040), and hypersensitive C-reactive protein (hs-CRP) elevation (95% CI: -0.572 to -0.118) in the CEUSL group than in the UAE or UAEM groups. At follow-up, all patients resumed normal menstruation, with no residual gestational sac on ultrasound imaging or sequel. Conclusions The pretreatment procedures were all technically successful, with good outcomes in different pretreatment procedures. Compared with UAE with or without methotrexate, CEUSL may be as effective and safe for pretreatment of CSP, with fewer adverse effects and shorter pretreatment time and hospital stay.

Abstract
AIM This study explored the protective function and mechanism of neocryptotanshinone (NEO) on cerebral ischemia. METHODS Lipopolysaccharide/γ-interferon(LPS/IFN-γ)was employed to mimic the polarization of mouse microglial cells BV2. After NEO treatment, the M1 polarization level of BV2 cells was identified using flow cytometry (FCM), fluorescent cell staining and enzyme linked immunosorbent assay(ELISA). Moreover, the mouse endothelial cells bEnd.3 were applied to be the study objects, which were intervened with NEO under the hypoxic condition. Thereafter, based on in-vitro tubule formation assay and fluorescence staining, the in-vitro tubule formation ability of bEnd.3 cells was detected. By adopting middle cerebral artery occlusion(MCAO) method, we constructed the mouse model of cerebral ischemia. After NEO intervention, the pathological changes of brain tissues were identified, while CD34 expression was measured by immunohistochemical (IHC) staining, nerve injury was detected by Nissl staining, and the changes in neurological behaviors of mice were also detected. RESULTS Our results showed that NEO suppressed M1 polarization of BV2 cells, which exerted its effect through suppressing NF-κB and STAT3 signals, thereby decreasing the levels of iNOS, CD11b and inflammatory factors. NEO stimulated tubule formation in bEnd.3 cells based on the hypoxic situation, which exerted its effect through activating the Vascularendothelial growth factor-Vascular Endothelial Growth Factor Receptor 2-Notch homolog 1(VFGF-VEGFR2-Notch1) signal. Furthermore, NEO suppressed cerebral ischemia in mice and lowered the ischemic penumbra. NEO also improved the neurological behaviors of mice, increased the CD34 levels and decreased the expression of inflammatory factors. CONCLUSION NEO has well protective effect against cerebral ischemia, and its mechanisms are related to suppressing M1 polarization of microglial cells and promoting cerebral angiogenesis, which are the mechanisms of NEO in treating ischemic encephalopathy.

Abstract
AIM To investigate the predictive value of 68Ga-labelled prostate-specific membrane antigen-11 (68Ga-PSMA-11) integrated positron-emission tomography (PET)/computed tomography (CT) in PBRM1-deficient clear cell renal cell carcinoma (ccRCC). MATERIALS AND METHODS A total of 41 patients with ccRCC, were enrolled retrospectively and underwent 68Ga-PSMA-11 PET/CT preoperatively. Radiological parameters, including CT attenuation value and maximum standard uptake value (SUVmax), were derived. Immunohistochemical and multiple immunofluorescences staining were performed to evaluate the PBRM1 status and immune response. The predictive value of imaging factors was analysed using a receiver operator characteristic curve analysis. Univariate and multivariate logistic regression analyses were used to investigate the relationship between clinical and radiological variables and PBRM1 status. RESULTS A total of 41 patients were included in this study, with 14 patients having PBRM1-deficient status. The tumour diameter on imaging and SUVmax differed significantly in patients with different PBRM1 expression statuses and no difference in CT attenuation was identified. Univariate and multivariate logistic regression analyses showed SUVmax was an obvious predictor for identification of PBRM1-deficient tumours. In addition, PBRM1-deficient tumours tended to be accompanied by greater cytotoxic T-cell infiltration, although most of them were in an exhausted state. CONCLUSIONS 68Ga-PSMA-11 PET/CT could be used to discriminate invasive PBRM1-deficient ccRCC.

Abstract
This work aimed to investigate the effect of aurantiamide (Aur) in promoting the M2 polarization of microglial cells to improve the cognitive ability of mice with Alzheimer's disease (AD). The M2 polarization of BV2 cells was induced by interleukin-4 (IL-4) treatment.Aur promoted the M2 polarization of BV2 cells, and up-regulated the expression of CD206 and SOCS3. In the meantime, it increased TGF-β1, Arg-1 and IL-10 levels, and promoted the polarization of JAK1-STAT6. Treatment with STAT6 inhibitor antagonized the effect of Aur. Besides, the cognitive ability of AD mice was improved after Aur treatment, meanwhile, the expression of CD206 was up-regulated, while that of IBA-1 was down-regulated. Aur promotes the M2 polarization of microglial cells to improve the cognitive ability of AD mice, and such effect is related to the STAT6 signal.

Abstract
Objective: To explore the feasibility and efficacy of radiofrequency coblation assisted transoral surgery for the treatment of supraglottic laryngeal carcinoma by comparing with concurrent patients treated with conventional transcervical approach. To clarify the advantages of different surgical methods and to summarize the experience of supraglottic carcinoma radiofrequency ablation. Methods: Forty-six patients with supraglottic laryngeal carcinoma treated in department of otorhinolaryngology head and neck surgery, Peking University First Hospital from March 2014 to January 2021 were analyzed retrospectively. Among them(43 males, 3 females, aged from 45 to 79 years old), 23 patients were treated with radiofrequency coblation and 23 patients with partial laryngectomy with conventional transcervical approach. The operation time, intra-operative blood loss volume, recovery time, inpatient total medical cost and follow-up information of the two groups were analyzed. SPSS 26.0 software was used for statistical analysis. Results: There were no significant differences in age, gender, TNM staging,tumor staging and postoperative radiotherapy between the two groups (all P>0.05).The operation time, intra-operative blood loss volume, recovery time, inpatient total medical cost of the RFC-TOS group were110.0(60.0,150.0)min,5.0(5.0,30.0)ml,3.0(2.0,5.0)days,6.0(4.0,14.0)days and 26 100.7(16 145.5,47 044.4)yuan. The data of conventional transcervical approach group were 205.0(156.5,272.3)min, 150.0(50,200) ml, 18.0(16.3,22.8)days and 56520.1(440 992.5,67 109.9)yuan, (Z=-4.03, -4.94, -4.97, -4.98 and -4.13;all P<0.001).The 5-year local control rate, disease-specific survival rate and overall survival rate of the two groups were 86.96%,95.65%,91.30% and 86.96%,91.30%,73.90% renspectively, which had no significant difference between the two groups(all P>0.05). Conclusions: Compared with conventional transcervical surgeries, RFC-TOS could be a reliable new surgical option for organ-function preservation strategy in the treatment of supraglottic laryngeal carcinoma.The RFC is a suitable new technique and deserving more multi-center clinical trials for its clinical promotion.

Abstract
Toll-like receptor 4 (TLR4) is a signaling molecule responsible for the expression of hepcidin (Hepc), while myeloid differentiation protein 2 (MD2) is one major accessory protein of TLR4. This study focuses on exploring the neurocyte ferroptosis mediated through the regulation of Hepc expression by MD2, which is also one of the mechanisms for postoperative cognitive dysfunction (POCD). An experimental study was carried out using aged wild-type (Wt) and MD2 transgenic (Tg) mice. The neurocyte ferroptosis and POCD in the mice were assessed following splenectomy. Morris water maze was utilized to assess the neurocognitive abilities, hematoxylin and eosin (H&E) assay was performed to examine histopathology, and Nissl staining was used to evaluate the neurocyte damage. The Fe2+ , superoxide dismutase(SOD), malondialdehyde (MDA), glutathione(GSH), and glutathione peroxidase 4 (GPX4) levels were determined with kits. The expressions of transferrin receptor (TFR), Hepc, and MD2 were measured by Western blotting, while the expressions of TFR and GPX4 were measured by immunohistochemical staining. In Tg mice, we observed neurocyte ferroptosis and POCD following treatment with an MD2 inhibitor. PC12 cells were used as a neurocyte model. Ferroptosis was induced after treatment with an MD2 inhibitor, and the cell viability was assayed by Cell Counting Kit-8. Immunofluorescent staining was used to measure the TFR and GPX4 expressions. Meanwhile, the intracellular levels of Fe2+ , SOD, MDA, GSH, GPX4, and Hepc were also measured. POCD occurred among aged Wt and Tg mice. The Tg-POCD mice had more apparent POCD than the Wt-POCD mice. Nissl and H&E staining revealed neurocyte damage in brain tissues. Besides this, the Fe2+ and MDA expressions were upregulated, while the SOD, GSH, and GPX4 expressions were downregulated. Elevations in tissue levels of TFR, Hepc, and MD2 were observed, which were higher than those of Wt-POCD mice. After treatment with an MD2 inhibitor, the POCD could be prominently ameliorated in Tg-POCD mice, the Fe2+ and MDA levels could be reduced, while the SOD, GSH, and GPX4 levels could be elevated. In the PC12 model, ferroptosis could be suppressed by inhibiting the expression of MD2. MD2 is capable of regulating neurocyte ferroptosis by promoting Hepc expression, which has great potential as a novel target for POCD therapy.

Abstract
This study aimed to investigate the mechanism of salvianolic acid C (SAC), the active ingredient in Salvia miltiorrhiza, in improving cerebral ischemia injury. The mouse microglial cells BV2 and mouse endothelial cells bEnd.3 were used as the objects of study. LPS/IFN-γ was applied to simulate the BV2 polarization, and bEnd.3 cells were treated under hypoxic condition. The BV2 cell polarization level was measured through flow cytometry (FCM), the TLR4 and MyD88 expression levels were detected by fluorescence staining, whereas the expression of inflammatory factors TNF-α, IL-6 and IL-1β was analyzed through ELISA. Tubule formation assay was also conducted to observe the tubule formation ability of bEnd.3 cells in vitro, and the level of VEGFR2 was detected by fluorescence staining. Cells were treated with the PKM2 inhibitor IN3, aiming to observe the influence of SAC on glycolysis of BV2 cells. In addition, the mouse model of cerebral ischemia was constructed through the middle cerebral artery occlusion (MCAO) method, and the pathological changes in brain tissues were detected after SAC intervention. Meanwhile, the levels of IBA-1, CD31 and ZO-1 were determined through histochemical staining. Nissl staining to detect nerve cell damage. In BV2 cell experiment, SAC suppressed the M1 polarization of BV2 cells, reduced the inflammatory factor levels, and inhibited the activation of TLR4 signal through suppressing glycolysis. When PKM2 was suppressed, the effects of SAC were antagonized. In the bEnd.3 model, SAC promoted tubule formation in bEnd.3 cells under hypoxic condition, and increased the expression of VEGFR2 and Notch1. In the mouse model, SAC improved the neurological function in MCAO mice, and inhibited the activation of microglial cells and the expression of inflammatory factors. At the same time, SAC up-regulated the expression of ZO-1 and CD31, and maintained the blood-brain barrier (BBB) function. As a major component of Salvia miltiorrhiza, SAC can suppress microglial cell polarization and promote tubule formation in endothelial cells to exert the neurological repair function in cerebral ischemia. SAC is a multi-functional neuroprotective small molecule.

Abstract
OBJECTIVE To investigate the effect of interference of P2X4 receptor expression in tumor-associated macrophages (TAMs) on invasion and migration of glioma cells. METHODS C57BL/6 mouse models bearing gliomas in the caudate nucleus were examined for glioma pathology with HE staining and expressions of Iba-1 and P2X4 receptor with immunofluorescence assay. RAW264.7 cells were induced into TAMs using conditioned medium from GL261 cells, and the changes in mRNA expressions of macrophage polarization-related markers and the mRNA and protein expressions of P2X4 receptor were detected with RT-qPCR and Western blotting. The effect of siRNA-mediated P2X4 interference on IL-1β and IL-18 mRNA and protein expressions in the TAMs was detected with RT-qPCR and Western blotting. GL261 cells were cultured in the conditioned medium from the transfected TAMs, and the invasion and migration abilities of the cells were assessed with Transwell invasion and migration experiment. RESULTS The glioma tissues from the tumor-bearing mice showed a significantly greater number of Iba-1-positive cells, where an obviously increased P2X4 receptor expression was detected (P=0.001), than the brain tissues of the control mice (P < 0.001). The M2 macrophage markers (Arg-1 and IL-10) and M1 macrophage markers (iNOS and TNF-α) were both significantly up-regulated in the TAMs derived from RAW264.7 cells (all P < 0.01), but the up-regulation of the M2 macrophage markers was more prominent; the expression levels of P2X4 receptor protein and mRNA were both increased in the TAMs (P < 0.05). Interference of P2X4 receptor expression significantly lowered the mRNA(P < 0.01)and protein (P < 0.01, P < 0.05)expression levels of IL-1β and IL-18 in the TAMs and obviously inhibited the ability of the TAMs to promote invasion and migration of the glioma cells (P < 0.05). CONCLUSION Interference of P2X4 receptor in the TAMs suppresses the migration and invasion of glioma cells possibly by lowering the expressions of IL-1β and IL-18.

Abstract
OBJECTIVE To explore the clinical value of three-dimensional (3D) visualization technique in laparoscopic D3 radical resection of right colon cancer. METHODS We retrospectively analyzed the clinical data of 73 patients with right colon cancer undergoing laparoscopic D3 radical operation in our hospital between May, 2019 and March, 2021. Among these patients, 41 underwent enhanced CT examination with 3D visualization reconstruction to guide the actual operation, and 32 underwent enhanced CT examination only before the operation (control group). In 3D visualization group, we examined the coincidence rate between the 3D visualization model and the findings in surgical exploration of the anatomy and variations of the main blood vessels, supplying vessels of the tumor, and the tumor location, and the coincidence rate between the actual surgical plan for D3 radical resection of right colon cancer and the plan formulated based on the 3D model. The operative time, estimated blood loss, unexpected injury of blood vessels, number of harvested lymph nodes, mean time of the first flatus, complications, postoperative hospital stay and postoperative drainage volume were compared between the two groups. RESULTS The operative time was significantly shorter in 3D visualization group than in the control group (P < 0.05). The volume of blood loss, proportion of unexpected injury of blood vessel, the number of harvested lymph nodes, time of the first flatus, proportion of complications, postoperative hospital stay and postoperative drainage volume did not differ significantly between the two groups (P > 0.05). In the 3D visualization group, the 3D visualization model clearly displayed the shape and direction of the colon, the location of the tumor, the anatomy and variation of the main blood vessels and the blood vessels supplying the cancer, and showed a coincidence rate of 100% with the findings by surgical exploration. The surgical plan for D3 radical resection of right colon cancer was formulated based on the 3D model also showed a coincidence rate of 100% with the actual surgical plan. CONCLUSION The 3D visualization reconstruction technique allows clear visualization the supplying arteries of the tumor and their variations to improve the efficiency, safety and accuracy of laparoscopic D3 radical resection of right colon cancer.

Abstract
Acute lymphoblastic leukemia (ALL) is a malignancy associated with altered lymphoid precursor hyperplasia and accompanied with different genetic mutations. Few studies have been reported on the association between gene mutations and clinical features of IKZF1 mutation in children with B-cell ALL (B-ALL). We investigated clinical and genetic characteristics in 200 newly diagnosed pediatric B-ALL through multiplex ligation-dependent probe amplification (MLPA) and targeted next-generation sequencing (NGS) method. We found that IKZF1 mutations, including large segment deletions, small insertions or deletions (InDels) and single nucleotide variations (SNVs), were detected in 22 patients with a positive mutation rate of 11.0%. IKZF1 mutation was significantly associated with higher WBC count (19.38 × 109/L vs. 5.80 × 109/L, p = 0.002). Compared with IKZF1 wild-type cases, a higher frequency of IL7R gene mutation was discovered in IKZF1 mutant cases (9.1% vs. 0.0%, p = 0.012). Patients with IKZF1 mutation were less sensitive to glucocorticoid induction than patients without IKZF1 mutation (63.6% vs. 9.0%, p < 0.001). On the 15th day of induction, minimal residual disease (MRD) > 10−3 level were higher in IKZF1 mutant patients than wild-type patients (45.5% vs. 22.3%, p = 0.018). In conclusion, our study reveals the association between genetic mutations and clinical features in Chinese children with B-ALL, which might contribute to molecular classification, risk stratification and prognosis evaluation, and provide new ideas for targeted therapy in ALL.

Abstract
Here, we introduced the first case of acute myeloid leukemia (AML) with RARG-NUP98 in a pediatric patient. The young male presented with structural and functional abnormalities similar to hypergranular acute promyelocytic leukemia, but was resistant to all transretinoic acids and arsenic trioxide. Till date, only 12 adult AML cases involving RARG rearrangement have been reported. At present, there is no standardized or optimal treatment option for this AML subtype. Disease management may typically require a joint treatment strategy involving chemotherapy, immunotherapy, and support therapy. In this study, we report the clinical manifestations and experimental results of a 10-year-old male and review other cases of RARG gene rearrangement reported in the literature.

Abstract
Objective: To analyze the early outcome of one-stage hybrid technique in the treatment of Stanford type-A aortic dissection involving the arch and compare its therapeutic efficacy with the classical frozen elephant trunk technique (FET). Methods: A total of 106 patients with Stanford type-A aortic dissection involving the arch in Department of Cardiac and Vascular Surgery, 1st Affiliated Hospital of Soochow University from October 2015 to October 2019 was collected. All patients in this group were treated with one-stage hybrid technique (modified arch debranching technique) without deep hypothermia circulation. Meanwhile, 30 patients with Stanford type A dissection involving the arch who underwent FET from January 2014 to September 2015 were collected. The therapeutic effects of the two surgical methods were analyzed and compared. Results: The age [M (Q1, Q3)] of 106 patients in hybrid group was 49.0 (40.0, 55.0) years, including 89 males and 17 females. The age [M(Q1, Q3)] of 30 patients in FET group was 49.5 (41.5, 65.3) years, including 24 males and 6 females. The time [M(Q1, Q3)] of using ventilator in hybrid group was 56.0 (38.0, 72.0) h, which was shorter than 127.0 (92.0, 145.0) h in FET group (P<0.001). The incidence of cerebral infarction in hybrid group was 2.8% (3 cases), which was lower than 13.3% (4 cases) in FET group (P=0.042); the incidence of postoperative renal insufficiency in hybrid group was 7.5% (8 cases), which was lower than 23.3% (7 cases) in FET group (P=0.023); the ICU time [M (Q1, Q3)] in hybrid group was 8.0 (6.0, 10.0) d, which was shorter than 14.0 (8.3, 24.0) d in FET group (P<0.001). Conclusion: Compared with FET, one-stage hybrid technology is safer and more effective in the treatment of Stanford type A aortic dissection involving the arch. Its short-term therapeutic efficacy appears good.

Abstract
Oridonin (Ori) is a kind of diterpenoid small molecule, but its role in nonalcoholic fatty liver disease (NAFLD) has not been reported yet. This study aimed to explore the pharmacological function of Ori in liver protection through the reactive oxygen species (ROS)-mediated polarization of Kupffer cells (KCs). In the present work, KCs were adopted for study in vitro. To be specific, LPS and IFN-γ were utilized to induce M1 polarization, then the influence of Ori intervention on the expression of inflammatory factors IL-1β, IL-6 and TNF-α was detected by enzyme-linked immunosorbent assay (ELISA), that of CD86 and P65 was measured through fluorescence staining, that of p-P65 and p-P50 was detected by Western blotting (WB) assay, and ROS expression was measured by using the DCFH-DA probe. The C57BL/6J mice were fed with the high fat diet (HFD) to construct the NAFLD model, and intervened with Ori. The blood glucose (BG), body weight (BW), food intake and water intake of mice were monitored; meanwhile, glucose and insulin tolerance tests were conducted. The liver tissues of mice were subjected to H&E staining and oil red O staining. Moreover, the serum ALT, AST and TG levels in mice were monitored, the CD86 and CD206 levels were measured through histochemical staining, the expression of inflammatory factors was detected by ELISA, and the p-P65 and p-P50 protein levels were detected by WB assay. Ori suppressed the M1 polarization of KCs, reduced the levels of inflammatory factors, and decreased the expression of ROS, p-P65 and p-P50. In animal experiments, Ori improved lipid deposition and liver injury in the liver tissues of NAFLD mice, increased the proportion of M2 cells (up-regulated CD206 expression), reduced that of M1 cells (down-regulated CD86 expression), and decreased the serum ALT, AST and TG levels. This study discovered that Ori suppressed ROS production and regulated the M1 polarization of KCs, thus protecting the liver in NAFLD.

Abstract
Objective: To identify age and gender standardized body mass index among children and adolescents and explore their associations with high blood pressure (HBP) in late adolescence. Methods: The current study was based on the Health Promotion Program for Children and Adolescents, school-based surveillance successively conducted from 2012 to 2019 in Suzhou, China. A total of 11 812 children and adolescents aged 16-18 years, who had ≥4 examination records during 2012-2018 and were also involved in a surveillance program in 2019, were included. Latent class growth mixture modeling was used to identify the BMI-Z trajectories in different genders, and multivariate logistic regression was used to analyze the associations between different BMI-Z trajectories and risk of HBP in late adolescence. Results: Six distinct BMI-Z trajectories were determined for both genders:thin, slightly thin,standard, declining, overweight, and obese. Compared with the regular group, the obesity group had 94.0% (OR=1.94, 95%CI: 1.43-2.63) and 107.0% (OR=2.07, 95%CI: 1.33-3.22) increased risk of developing HBP in late adolescence in boys and girls, respectively. However, a neutral association was found between the descending group and HBP in late adolescence. Conclusions: Persistent obesity in children may increase the risk of HBP in their late adolescence. If an obese child restores normal weight before late adolescence, the risk of HBP may reduce.

Abstract
Our previous research has found that miRNA‐22 can inhibit the occurrence of pyroptosis by targeting GSDMD and decrease the production and release of inflammatory factors. In consideration of the therapeutic effects of mesenchymal stem cells (MSCs), MSCs‐EV were loaded with miRNA‐22 (EV‐miRNA‐22) to investigate the inhibitory effect of EV‐miRNA‐22 on the inflammatory response in SCI in rats in this study. LPS/Nigericin (LPS/NG) was used to induce pyroptosis in rat microglia in vitro. Propidium iodide (PI) staining was performed to observe cell permeability, lactate dehydrogenase (LDH) release assay was adopted to detect cytotoxicity, flow cytometry was conducted to detect pyroptosis level, immunofluorescence (IF) staining was utilized to observe the expression level of GSDMD (a key protein of pyroptosis), Western blot was performed to detect the expression of key proteins. For animal experiments, the T10 spinal cord of rats was clamped by aneurysm clip to construct the SCI model. BBB score, somatosensory evoked potential (SEP) and motor evoked potential (MEP) were performed to detect nerve function. HE staining and Nissl staining were used to detect spinal cord histopathology and nerve cell damage. EV‐miRNA‐22 could inhibit the occurrence of pyroptosis in microglia, suppress the cell membrane pore opening, and inhibit the release of inflammatory factors and the expression of GSDMD. In addition, EV‐miRNA‐22 showed higher pyroptosis‐inhibiting ability than EV. Consequently, EV‐miRNA‐22 could inhibit the nerve function injury after SCI in rats, inhibit the level of inflammatory factors in the tissue and the activation of microglia. In this study, we found that miRNA‐22‐loaded MSCs‐EV (EV‐miRNA‐22) could cooperate with EV to inhibit inflammatory response and nerve function repair after SCI.
