Abstract
BACKGROUND Droplet digital PCR (ddPCR) is widely applied to monitor measurable residual disease (MRD). However, there are limited studies on the feasibility of ddPCR-MRD monitoring after allogeneic hematopoietic stem cell transplantation (allo-HSCT), especially targeting multiple molecular markers simultaneously. METHODS Our study collected samples from patients with acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS) in complete remission after allo-HSCT between January 2018 and August 2021 to evaluate whether posttransplant ddPCR-MRD monitoring can identify patients at high risk of relapse. RESULTS Of 152 patients, 58 (38.2%) were MRD positive by ddPCR within 4 months posttransplant, with a median variant allele frequency of 0.198%. The detectable DTA mutations (DNMT3A, TET2, and ASXL1 mutations) after allo-HSCT were not associated with an increased risk of relapse. After excluding DTA mutations, patients with ddPCR-MRD positivity had a significantly higher cumulative incidence of relapse (CIR, 38.7% vs. 9.7%, P < 0.001) and lower rates of relapse-free survival (RFS, 55.5% vs. 83.7%, P < 0.001) and overall survival (OS, 60.5% vs. 90.5%, P < 0.001). In multivariate analysis, ddPCR-MRD positivity of non-DTA genes was an independent adverse predictor for CIR (hazard ratio [HR], 4.02; P < 0.001), RFS (HR, 2.92; P = 0.002) and OS (HR, 3.12; P = 0.007). Moreover, the combination of ddPCR with multiparameter flow cytometry (MFC) can further accurately identify patients at high risk of relapse (F+/M+, HR, 22.44; P < 0.001, F+/M-, HR, 12.46; P < 0.001 and F-/M+, HR, 4.51; P = 0.003). CONCLUSION ddPCR-MRD is a feasible approach to predict relapse after allo-HSCT in AML/MDS patients with non-DTA genes and is more accurate when combined with MFC.

Abstract
The Applications of silica aerogel are limited due to its brittleness and low strength. As a result, it is essential to strengthen and toughen it. Organic nanofibers are one of the preferred reinforcement materials. In this work, we designed and fabricated flexible and compressible nanostructure-assembled aramid nanofiber/silica composites aerogel (ANF/SiO2 aerogel) to improve the mechanical strength and flexibility of silica aerogel without compromising thermal insulation properties. The aramid nanofiber/silica composite aerogels were prepared by immersing the aramid nanofiber wet gel into the silica sol for a certain period of time followed by freeze drying without solvent replacement. The surface modifier 3-aminopropyltriethoxysilane (APTES) was used as a coupling agent to form chemical linkage between the ANF fiber and silica gel. It was observed that APTES can effectively drive the silica sol to infuse into ANF hydrogel, promoting the assembly of silica gel onto the fiber surface and a uniform distribution in the network of ANF. The compressive resilience, thermal stability, and thermal insulation properties of the composite aerogels were evaluated by inducing the silica aerogel into the ANF network to form a protective layer on the fiber and change the pore structure in the ANF network.

Abstract
Gestational diabetes mellitus (GDM) is a frequent complication of pregnancy. The specific mechanisms underlying GDM have not yet been fully elucidated. Contemporary research indicates a potential association between liver enzyme irregularities and an increased risk of metabolic disorders, including diabetes. The alanine aminotransferase (ALT) level is recognized as a sensitive marker of liver injury. An increase in ALT levels is hypothesized to be linked to the pathogenesis of insulin resistance and diabetes. Nonetheless, the definitive causal link between ALT levels and GDM still needs to be determined. This investigation utilized two-sample Mendelian randomization (MR) to examine the genetic causation between alanine aminotransferase (ALT) and GDM. We acquired alanine aminotransferase (ALT)-related GWAS summary data from the UK Biobank, Million Veteran Program, Rotterdam Study, and Lifeline Study. Gestational diabetes data were obtained from the FinnGen Consortium. We employed various MR analysis techniques, including inverse-variance weighted (IVW), MR Egger, weighted median, simple, and weighted weighting. In addition to MR-Egger intercepts, Cochrane's Q test was also used to assess heterogeneity in the MR data, and the MR-PRESSO test was used to assess horizontal pleiotropy. To assess the association's sensitivity, a leave-one-out approach was employed. The IVW results confirmed the independent risk factor for GDM development, as indicated by the ALT level (p = .011). As shown by leave-one-out analysis, horizontal pleiotrophy did not significantly skew the causative link (p > .05). Our dual-sample MR analysis provides substantiated evidence of a genetic causal relationship between alanine aminotransferase (ALT) levels and gestational diabetes.

Abstract
Data on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients at early stage of immune reconstitution after hematopoietic stem cell transplantation (HSCT) are limited. In the present study, we retrospectively investigated the incidence and clinical features of SARS-CoV-2 infection in patients who underwent HSCT in 2022. Patients (allo-HSCT, n = 80; auto-HSCT, n = 37) were consecutively included in the study. The SARS-CoV-2 infection rate was 59.8%, and the median interval of HSCT to coronavirus disease 2019 (COVID-19) was 4.8 (range: 0.5-12) months. Most patients were categorized as mild (41.4%) or moderate (38.6%), and 20% as severe/critical. No deaths were attributable to COVID-19. Further analysis showed that lower circulating CD8+ T-cell counts and calcineurin inhibitor administration increased the risk of SARS-CoV-2 infection. Exposure to rituximab significantly increased the probability of severe or critical COVID-19 compared with that of mild/moderate illness (P < .001). In the multivariate analysis, rituximab use was associated with severe COVID-19. Additionally, COVID-19 had no significant effect on immune reconstitution. Furthermore, it was found that Epstein-Barr virus infection and rituximab administration possibly increase the risk of developing severe illness. Our study provides preliminary insights into the effect of SARS-CoV-2 on immune reconstitution and the outcomes of allo-HSCT recipients.

Abstract
The study aims to search and identify differentially expressed genes (DEGs) in cervical cancer tissues as novel biomarkers to predict cervical cancer prognosis. The Cancer Genome Atlas (TCGA) data on gene expression profiles in cervical cancer were downloaded and analyzed using R software to identify DEGs in cervical cancer tissues. miRNAs targeted by differentially expressed long non-coding RNAs (DElncRNAs) and mRNAs targeted by microRNAs (miRNAs) were identified using the online miRcode, miRTarBase, TargetScan, and miRDB tools. The ceRNA network and lncRNA expression modules in cervical cancer tissues were constructed using weighted gene co-expression network analysis (WGCNA) and analyzed bioinformatically. The Kaplan-Meier analysis was performed to confirm these DEGs as prognostic markers. Immunohistochemical (IHC) analysis was used to verify expression of the hub genes in 10 paired cervical cancer and normal tissues. A total of 1914 DEmRNAs, 210 DElncRNAs, and 67 DEmiRNAs were identified in cervical cancer samples. There were 39 lncRNAs, 19 miRNAs, and 87 mRNAs involved in the ceRNA network and 25 DElncRNAs, three DEmiRNAs, and four mRNAs involved in the ceRNA sub-network. CACNA1C-AS1 was associated with the yellow and blue modules in the ceRNA sub-network, and LIFR-AS1 was associated with the blue module. The DEmRNAs were involved in cancer-related pathways, and three hub genes (i.e., E2F1, CCNB1, and CCNE1) were highly expressed in cervical squamous cell carcinoma and adenocarcinoma tissues and associated with the prognosis of patients. The ceRNA network and WGCNA analyses are useful to identify novel DEGs that can serve as prognostic markers in cervical cancer. The DEGs will be validated in future studies.

Abstract
Herein, we reported a general and green synthetic strategy for photochromic functional alginate derivatives grafting with isoindolinone spiroxanthenes. Under mild condition, diverse 2-aminoalkyl isoindolinone spiroxanthene derivatives have been prepared from organic photochromic isobenzofuranone spiroxanthenes (including rhodamine B, rhodamine 6G and fluorescein), and grafted on alginate chains through amidation reaction using diamine as a linkage with water as a green solvent at room temperature. The photochromic properties of the fluorophores-modified polymers and the effect of pH value have been explored. Under acid conditions, the spiroisoindolinone rings of alginate derivatives are opened resulting in showing absorption bands and fluorescence with orange to green emission, while the alginate derivatives turned to colourless under basic conditions which is reversibly. In addition to biodegradability and biocompatibility, the polymers exhibit good film-forming properties simultaneously. The films and fibers produced from the alginate derivatives also project good fluorescence properties.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Vascular endothelial cell senescence is associated with cardiovascular complications in diabetes. Essential oil from Fructus Alpiniae zerumbet (Pers.) B.L.Burtt & R.M.Sm. (EOFAZ) has potentially beneficial and promising diabetes-related vascular endothelial cell senescence-mitigating effects; however, the underlying molecular mechanisms remain unclear. AIM OF THE STUDY To investigate the molecular effects of EOFAZ on vascular endothelial cell senescence in diabetes. MATERIALS AND METHODS A diabetes mouse model was developed using a high-fat and high-glucose diet (HFD) combined with intraperitoneal injection of low-dose streptozotocin (STZ, 30 mg/kg) and oral treatment with EOFAZ. 4D label-free quantitative proteomics, network pharmacology, and molecular docking techniques were employed to explore the molecular mechanisms via which EOFAZ alleviates diabetes-related vascular endothelial cell senescence. A human aortic endothelial cells (HAECs) senescence model was developed using high palmitic acid and high glucose (PA/HG) concentrations in vitro. Western blotting, immunofluorescence, SA-β-galactosidase staining, cell cycle, reactive oxygen species (ROS), cell migration, and enzyme linked immunosorbent assays were performed to determine the protective role of EOFAZ against vascular endothelial cell senescence in diabetes. Moreover, the PPAR-γ agonist rosiglitazone, inhibitor GW9662, and siRNA were used to verify the underlying mechanism by which EOFAZ combats vascular endothelial cell senescence in diabetes. RESULTS EOFAZ treatment ameliorated abnormal lipid metabolism, vascular histopathological damage, and vascular endothelial aging in diabetic mice. Proteomics and network pharmacology analysis revealed that the differentially expressed proteins (DEPs) and drug-disease targets were associated with the peroxisome proliferator-activated receptor gamma (PPAR-γ) signalling pathway, a key player in vascular endothelial cell senescence. Molecular docking indicated that the small-molecule compounds in EOFAZ had a high affinity for the PPAR-γ protein. Western blotting and immunofluorescence analyses confirmed the significance of DEPs and the involvement of the PPAR-γ signalling pathway. In vitro, EOFAZ and rosiglitazone treatment reversed the effects of PA/HG on the number of senescent endothelial cells, expression of senescence-related proteins, the proportion of cells in the G0/G1 phase, ROS levels, cell migration rate, and expression of pro-inflammatory factors. The protective effects of EOFAZ against vascular endothelial cell senescence in diabetes were aborted following treatment with GW9662 or PPAR-γ siRNA. CONCLUSIONS EOFAZ ameliorates vascular endothelial cell senescence in diabetes by activating PPAR-γ signalling. The results of the present study highlight the potential beneficial and promising therapeutic effects of EOFAZ and provide a basis for its clinical application in diabetes-related vascular endothelial cell senescence.

Abstract
OBJECTIVES Examining fear of cancer recurrence (FCR) among breast cancer survivors and their spouses, and the protective effect of family resilience on FCR among couples affected by breast cancer. DESIGN Cross-sectional survey design. SETTING Ten general grade IIIa (>500 beds) hospitals in southwest China. PARTICIPANTS Overall, 392 early breast cancer survivors and their spousal caregivers (N=392) were recruited from cancer centres in hospitals. PRIMARY AND SECONDARY OUTCOME MEASURES Spouses' and survivors' FCR were the primary outcome measures. Family resilience and perceived stress were the secondary outcome measures. Using a convenience sampling method, we collected data on-site using paper questionnaires. The Chinese version of the Family Resilience Assessment Scale, Perceived Stress Scale, Fear of Progression Questionnaire Short Form and Fear of Progression Questionnaire-Short Form for spouses were used to evaluate the outcomes. RESULTS The model accounted for 66.3% and 53.6% of the variance in spouses' FCR and survivors' FCR, respectively. Family resilience directly negatively affected perceived stress and spouses' and survivors' FCR (β=-0.22; β=-0.13; β=-0.19). Perceived stress was a partial mediator of the association between family resilience and survivors' FCR (β=-0.070; 95% CI :-0.151 to -0.022). Spouses' FCR partially mediated the association between family resilience and survivors' FCR (β=-0.048; 95% CI= -0.092 to -0.015). Perceived stress and spouses' FCR played a significant chain-mediated role between family resilience and survivors' FCR (β=-0.061; 95% CI: -0.119 to -0.022). CONCLUSIONS Family-centred approaches to reducing survivors' perceived stress can improve the psychological well-being of couples affected by breast cancer and ultimately reduce FCR. Medical staff should consider the psychological feelings of survivors and their spousal caregivers when devising the intervention plan, which should address the families' potential and mobilise family and community resources for increasing family resilience.

Abstract
OBJECTIVES This investigation aims to explore relationships between adult attachment, emotional self-disclosure, and quality of life (QoL). DATA SOURCES The study sample completed the Chinese versions of the Experiences in Close Relationships Inventory, the Functional Assessment of Cancer Therapy-Breast Scale, and the Distress Disclosure Index between October 2021 and March 2022. The relationships between adult attachment, emotional self-disclosure, and QoL were investigated using a multiple mediation effects test and structural equation modeling. CONCLUSION Attachment anxiety and avoidance were risk factors for young Chinese breast cancer survivors' emotional self-disclosure and QoL. Emotional self-disclosure mediates the association between attachment anxiety or avoidance and QoL. Assessing and easing attachment anxiety and avoidance may improve the emotional self-disclosure and QoL of young breast cancer survivors. IMPLICATIONS FOR NURSING PRACTICE This study confirms that adult attachment plays an important role in young breast cancer patients' adaptation to the disease and that high adult anxiety and avoidance levels can significantly reduce emotional self-disclosure and QoL in young breast cancer survivors. Identifying attachment patterns can help caregivers better understand patients' responses, adaptation, and treatment adherence to cancer, thereby helping caregivers develop targeted and personalized cancer care practice programs or psychotherapy interventions to improve patients' physical and mental health outcomes.

Abstract
BACKGROUND Implant infection continues to be the most common complication of breast reconstruction, and it can lead to serious consequences of implant loss. Recently, endoscopic-assisted nipple-sparing mastectomy with direct-to-implant breast reconstruction is being performed more frequently, with similar prosthetic infection incidence compared to conventional techniques. But there is little information published in the literature on the management of periprosthetic infection in endoscopic-assisted breast reconstruction. METHODS A retrospective review was performed of patients who underwent endoscope-assisted breast reconstruction and developed periprosthetic infection between January 2020 and December 2022. Prosthesis infection was defined as any case where antibiotics were given, beyond the surgeon's standard perioperative period, in response to clinical signs such as swelling, pain, erythema, increased temperature, fever, etc. We summarized our clinical approach and treatment protocol for periprosthetic infection patients. Collected data include preoperative basic information, surgical details, postoperative data, and outcomes. RESULTS A total of 580 patients (713 reconstructions) underwent endoscopic-assisted immediate breast reconstruction. There were 58 patients developed periprosthetic infection, 14 of whom had bilateral prosthesis reconstruction with unilateral prosthesis infection. The incidence of infection was 10.0%. Average follow-up was 17.3 ± 8.9 months (range = 2-37 months). Of the 58 patients, 53 (91.4%) patients successful salvaged implant and 5(8.6%) patients removed prosthesis. During follow-up, Baker III capsular contracture occurred in 2 patients (3.8%) who had radiotherapy. CONCLUSION Our management of prosthesis infections in endoscopic-assisted breast reconstruction is easy, minimally invasive, and inexpensive. This method can be repeated if the implant infection does not improve after the first drainage. What's more, our data suggest that our prosthesis salvage of periprosthetic infection is effective.

Abstract
High-entropy ceramics exhibit various excellent properties owing to their high configurational entropy, which is caused by multi-principal elements sharing one lattice site. The configurational entropy will further increase significantly if multi-principal elements randomly share two different lattice sites. For this purpose, pseudobrookite phase containing two cationic lattice sites (A and B sites) is selected, and corresponding high-entropy pseudobrookite (M2+ 0.4 M3+ 1.2 )Ti1.4 O5 is synthesized. Herein, the distribution of the 2-valent and 3-valent cations in the A and B sites are analysed in depth. The distance between the A and B sites in the crystal structure models which are constructed by the Rietveld analysis is calculated and defined as distance d. Meanwhile, the atomic column positions in the STEM images are quantified by a model-based mathematical algorithm, and the corresponding distance d are calculated. By comparing the distance d, it is determine that the 2-valent and 3-valent cations are jointly and disorderly distributed in the A and B sites in high-entropy (M2+ 0.4 M3+ 1.2 )Ti1.4 O5 . The density functional theory (DFT) simulations also demonstrate that this type of crystal structure is more thermodynamically stable. The higher degree of cationic disorder leads to a higher configurational entropy in high-entropy (M2+ 0.4 M3+ 1.2 )Ti1.4 O5 , and endows high-entropy (M2+ 0.4 M3+ 1.2 )Ti1.4 O5 with very low thermal conductivity (1.187-1.249 W m-1 K-1 ).

Abstract
Few studies have performed comparative analysis of the outcome of hematopoietic stem cell transplantation from HLA-identical sibling donors (ISD-HSCT) in patients with or without anti-HLA Abs. In this study we retrospectively collected data from a multicenter study to analyze the distribution and impact of the pre-existing anti-HLA Abs in ISD-HSCT. Among 402 recipients, 111 were positive for anti-HLA Abs. Gender, time from diagnosis to transplantation and distribution of primary disease might be risk factors for the occurrence of anti-HLA Abs. We found that patients with anti-HLA Abs had delayed neutrophil engraftment and were more vulnerable to experience Cytomegalovirus (CMV) reactivation. The presence of anti-HLA Abs was proved to be an independent risk factor for neutrophil engraftment (HR 1.42 95% CI 1.13-1.80, p = 0.003) and CMV reactivation (HR 2.03 95% CI 1.19-3.46, p = 0.009). We found that anti-HLA Abs have a negative impact on the prognosis in the early period after transplantation from sibling donors and anti-HLA Abs was also an independent risk factor for the overall survival (OS) at 180 days (HR 2.32, 95% CI 1.03-5.27, p = 0.042) among female recipients. In conclusion, anti-HLA Abs have a negative impact on the prognosis early after ISD-HSCT.

Abstract
BACKGROUND Gemcitabine is a first-line chemotherapeutic agent for pancreatic cancer (PC); however, most patients who receive adjuvant gemcitabine rapidly develop resistance and recurrence. Cancer-associated fibroblasts (CAFs) are a crucial component of the tumor stroma that contribute to gemcitabine-resistance. There is thus an urgent need to find a novel therapeutic strategy to improve the efficacy of gemcitabine in PC cells under CAF-stimulation. PURPOSE To investigate if shikonin potentiates the therapeutic effects of gemcitabine in PC cells with CAF-induced drug resistance. METHODS PC cell-stimulated fibroblasts or primary CAFs derived from PC tissue were co-cultured with PC cells to evaluate the ability of shikonin to improve the chemotherapeutic effects of gemcitabine in vitro and in vivo. Glucose uptake assay, ATP content analysis, lactate measurement, real-time PCR, immunofluorescence staining, western blot, and plasmid transfection were used to investigate the underlying mechanism. RESULTS CAFs were innately resistant to gemcitabine, but shikonin suppressed the PC cell-induced transactivation and proliferation of CAFs, reversed CAF-induced resistance, and restored the therapeutic efficacy of gemcitabine in the co-culture system. In addition, CAFs underwent a reverse Warburg effect when co-cultured with PC cells, represented by enhanced aerobic glycolytic metabolism, while shikonin reduced aerobic glycolysis in CAFs by reducing their glucose uptake, ATP concentration, lactate production and secretion, and glycolytic protein expression. Regarding the mechanism underlying these sensitizing effects, shikonin suppressed monocarboxylate transporter 4 (MCT4) expression and cellular membrane translocation to inhibit aerobic glycolysis in CAFs. Overexpression of MCT4 accordingly reversed the inhibitory effects of shikonin on PC cell-induced transactivation and aerobic glycolysis in CAFs, and reduced its sensitizing effects. Furthermore, shikonin promoted the effects of gemcitabine in reducing the growth of tumors derived from PC cells and CAF co-inoculation in BALB/C mice, with no significant systemic toxicity. CONCLUSION These results indicate that shikonin reduced MCT4 expression and activation, resulting in inhibition of aerobic glycolysis in CAFs and overcoming CAF-induced gemcitabine resistance in PC. Shikonin is a promising chemosensitizing phytochemical agent when used in combination with gemcitabine for PC treatment. The results suggest that disrupting the metabolic coupling between cancer cells and stromal cells might provide an attractive strategy for improving gemcitabine efficacy.

Abstract
The study was aimed to analyze the seasonal pollen allergen spectrum of patients with allergic rhinitis (AR) in Nanchang city, and to provide evidence for improving the clinical diagnosis, treatment, prevention and epidemiology of seasonal AR. A retrospective analysis was conducted on the results of skin prick test (SPT) among 1 752 patients with AR in outpatient at Department of Otolaryngology, the First Affiliated Hospital of Nanchang University from September 2020 to August 2021 (a total of 1 069 males and 683 females, age ranged from 2 to 84 years old). SPSS 22.0 software was used to analyze the positive rates of main allergens and their differences in gender, age, and month of visit. Differences among groups were compared by student t test, Wilcox rank sum test, or χ2 test. The results showed that among 1 752 SPT-positive patients, the number of simple seasonal AR and the number of perennial combined seasonal AR were 102 (5.82%) and 281 (16.04%), respectively. There was no significant difference between male and female patients in positive seasonal pollen allergens (χ2=2.181, P>0.05), but the positive rate of indoor seasonal pollen allergens in males was higher than that in females (χ2=7.901, P<0.05). The seasonal pollen allergens ranking top 5 of the positive rates were willow (6.62%, 116/1 752), humulus scandens (5.71%, 100/1 752), rape (5.54%, 97/1 752), grey pigweed (4.62%, 81/1 752) and birch (3.60%, 63/1 752). The positive rates of indoor and seasonal pollen allergens increased first and then decreased in different age groups, and the highest positive rates of seasonal pollen allergens were in the age group of 31-40 years old, with statistical significance compared with other groups (χ2=61.269, P<0.05). The seasonal allergen positive rate showed two peaks in time: March to May and September to November. The positive rate of pollen in spring was 60.27% (132/219), which was significantly higher than that in autumn (39.73%,87/219) (χ2=9.247, P<0.05). The positive rate of pollen combination in spring and autumn was 68.29% (112/164), which was significantly higher than that in spring and autumn alone (18.9%,31/164) and (12.8%, 21/164) (χ2=14.731, P<0.05). In summary, pollen allergy in Nanchang City cannot be ignored, accounting for more than 20% of the total number of AR. The incidence of seasonal AR in Nanchang City showed two peaks (March to May and September to November). The common allergens for seasonal AR in Nanchang City were willow, humulus scandens, rape, grey chenopods and birch.

Abstract
The abnormal expression of follistatin‑like protein 1 (FSTL1) in various tumors is a crucial regulator of the biological process of tumorigenesis. Nonetheless, the regulatory role of FSTL1 in cervical cancer is yet to be elucidated. Hence, the present study aimed to explore the expression, function, and molecular mechanism of FSTL1 in cervical cancer. The expression of FSTL1 in normal and cervical cancer tissues was examined using quantitative reverse transcription‑polymerase chain reaction and immunohistochemistry assays. The effects of abnormal expression of FSTL1 on cervical cancer cells were assessed using colony formation, MTT, wound‑healing, Transwell, apoptosis, and nude mouse tumorigenicity assays. FSTL1‑related molecular mechanisms were screened using gene chip analysis. Western blotting analysis was used to verify the regulatory mechanisms of FSTL1 in cervical cancer. The results indicated that the expression of FSTL1 was downregulated in cervical cancer tissues and that its downregulation was associated with tumor differentiation, pathologic type, and infiltration depth. Moreover, FSTL1 inhibited the proliferation, migration, and invasion of cervical cancer cells as well as xenograft tumor growth and promoted cell apoptosis. In addition, the findings of gene chip analysis suggested that the differentially expressed genes of FSTL1 were predominantly enriched in multiple signaling pathways, of which the insulin‑like growth factor (IGF)‑1 signaling pathway was significantly activated. Western blotting suggested the involvement of FSTL1 in the regulation of the IGF‑1R/PI3K/AKT/BCL‑2 signaling pathway. These data establish the downregulation of FSTL1 in cervical cancer tissues. FSTL1 inhibited the proliferation, migration, and invasion of cervical cancer cells and promoted their apoptosis. Furthermore, xenograft tumor growth in nude mice was inhibited. FSTL1 may be involved in the regulation of the IGF‑1R/PI3K/AKT/BCL‑2 signaling pathway in cervical cancer. Therefore, FSTL1 may be employed as a novel biomarker to determine the extent of disease progression in patients with cervical cancer.

Abstract
This project aims to explore the repercussions of ritonavir on both the drug kinetics of clonidine in rats and clonidine metabolism in liver micro somes. Eighteen healthy male laboratory rats were haphazardly placed into groups: Group A, the control, Group B, got 20mg/kg ritonavir and Group C, got 180 mg/kg ritonavir. Ritonavir was administered to the rats by oral gavage and 30 minutes later, clonidine at 0.25mg/kg was administered for once. Moreover, rat and human liver micro somes, along with recombinant human CYP2D6*1, were used to study the inhibition effect of ritonavir on clonidine in vitro. The concentrations of clonidine and its metabolite were determined by the UPLC-MS/MS. The area under the curve (AUC) of clonidine increased (P<0.01) and clearance (CL) decreased significantly (P<0.01), after co-administration with 180mg/kg ritonavir. The half-maximal inhibitory concentration (IC50) of ritonavir was 11.48μmol/L in rat liver micro somes, 3.52μmol/L in human liver micro somes and 18.04μmol/L in CYP2D6*1. Our findings demonstrate that ritonavir exhibited an inhibitory effect on clonidine metabolism in vitro and in vivo. It suggests that concurrent use of clonidine with ritonavir required close monitoring of the clonidine plasma concentration to alert drug adverse reactions.

Abstract
Objective: To analyze the survival and influencing factors of chimeric antigen receptor (CAR) T-cell therapy in relapsed/refractory acute B-cell lymphoblastic leukemia (R/R B-ALL) . Methods: Clinical information of patients who received CAR-T-cell therapy and achieved complete remission of R/R B-ALL between May 2015 and June 2018 at the Shaanxi Provincial People's Hospital was obtained. Kaplan-Meier analysis was used to evaluate the overall survival (OS) and leukemia-free survival (LFS) times of patients, and Cox regression analysis was performed to analyze the prognostic factors that affect patient survival after CAR-T therapy. Results: Among the 38 patients with R/R B-ALL, 21 were men, with a median age of 25 (6-59) years and a median OS time of 18 (95% CI 3-33) months. Multivariate Cox regression analysis showed that positive MLL-AF4 fusion gene expression was an independent risk factor for OS and LFS (OS: HR=4.888, 95% CI 1.375-17.374, P=0.014; LFS: HR=6.683, 95% CI 1.815-24.608, P=0.004). Maintenance therapy was a protective factor for OS and LFS (OS: HR=0.153, 95% CI 0.054-0.432, P<0.001; LFS: HR=0.138, 95% CI 0.050-0.382, P<0.001). In patients with MRD negative conversion, LFS benefit (HR=0.209, 95% CI 0.055-0.797, P=0.022) and OS difference was statistically insignificant (P=0.111). Moreover, patients with high tumor burden were risk factors for OS and LFS at the level of 0.1 (OS: HR=2.662, 95% CI 0.987-7.184, P=0.053; LFS: HR=2.452, 95% CI 0.949-6.339, P=0.064) . Conclusion: High tumor burden and high-risk genetics may affect the long-term survival rate of patients with R/R B-ALL receiving CAR-T, and lenalidomide-based maintenance therapy may improve their prognosis.

Abstract
This study presents the degradation of rhodamine B (RhB) by photo Fenton-like (PF-like) process under visible light irradiation (λ > 380 nm) using cobalt phosphate microparticles (CoP-MPs). The effects of the initial concentration of RhB, pH value, CoP-MPs dosage, hydrogen peroxide (H2O2) concentration, and salts found in textile wastewater (such as NaNO3, Na2SO4, and NaCl) were investigated in detail. It was found that CoP-MPs can maintain high catalytic activity with wide pH values varying from 4 to 8. This indicated that the use of CoP-MPs overcame the low efficiency of Fenton-like reaction at neutral and even weakly alkaline pH. The PF-like degradation of RhB followed pseudo-first order kinetics in various conditions. Moreover, a comparison of experimental results showed that the PF-like system has good degradation ability for RhB and methyl blue (MB) solution, but is poor for methyl orange (MO) solution. The repeat experiments indicated that the chemical structures of CoP-MPs were stable. Furthermore, the Co2+ ions leaching to the solutions were measured by an inductively coupled plasma mass spectrometer (ICP-MS). Analysis of UV-vis spectra suggested that RhB was degraded by the formation of a series of N-de-ethylated intermediates followed by cleavage of the whole conjugate chromophore structure.HighlightsRhB can be effectively degraded in the PF-like process under visible light irradiation by CoP-MPs.The PF-like process can maintain high catalytic activity at neutral and even weakly alkaline pH.Degradation kinetics exhibited pseudo-first-order kinetics and were influenced by the key parameters.The variation in the UV-vis spectra of RhB was analyzed in detail to infer a possible degradation pathway.

Abstract
Purpose The accurate prediction of non-cirrhotic hepatocellular carcinoma (NCHCC) risk facilitates improved surveillance strategy and decreases cancer-related mortality. This study aimed to explore the correlation between immunogenic cell death (ICD) and NCHCC prognosis using The Cancer Genome Atlas (TCGA) datasets, and the potential prognostic value of ICD-related genes in NCHCC. Methods Clinical and transcriptomic data of patients with NCHCC patients were retrieved from TCGA database. Weighted gene co-expression network analysis was performed to obtain the NCHCC phenotype-related module genes. Consensus clustering analysis was performed to classify the patients into two clusters based on intersection genes among differentially expressed genes (DEGs) between cancer and adjacent tissues, NCHCC phenotype-related genes, and ICD-related genes. NCHCC-derived tissue microarray was used to evaluate the correlation of the expression levels of key genes with NCHCC prognosis using immunohistochemical staining. Results Cox regression analyses were performed to construct a prognostic risk score model comprising three genes (TMC7, GRAMD1C, and GNPDA1) based on DEGs between two clusters. The model stratified patients with NCHCC into two risk groups. The overall survival (OS) of the high-risk group was significantly lower than that of the low-risk group. Univariable and multivariable Cox regression analyses revealed that these signature genes are independent predictors of OS. Functional analysis revealed differential immune status between the two risk groups. Next, a nomogram was constructed, which demonstrated the potent distinguishing ability of the developed model based on receiver operating characteristic curves. In vitro functional validation revealed that the migration and invasion abilities of HepG2 and Huh7 cells were upregulated upon GRAMD1C knockdown but downregulated upon TMC7 knockdown. Conclusion This study developed a prognostic model comprising three genes, which can aid in predicting the survival of patients with NCHCC and guide the selection of drugs and molecular markers for NCHCC.

Abstract
Introduction Immunosuppression predisposes allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients to infection. Prompt and accurate identification of pathogens is crucial to optimize treatment strategies. This multi-center retrospective study aimed to assess the ability of metagenomic next-generation sequencing (mNGS) to detect causative pathogens in febrile allo-HSCT recipients and examined its concordance with conventional microbiological tests (CMT). Methods We performed mNGS and CMT on samples obtained from 153 patients with suspected infection during allo-HSCT. Patients were grouped based on their neutropenic status at the time of sampling. Results The mNGS test was more sensitive than CMT (81.1% vs. 53.6%, P<0.001) for diagnosing clinically suspected infection, especially in the non-neutropenia cohort. mNGS could detect fungi and viruses better than bacteria, with a higher sensitivity than CMT. Immune events were diagnosed in 57.4% (35/61) of the febrile events with negative mNGS results, and 33.5% (48/143) with negative CMT results (P=0.002). The treatment success rate of the targeted anti-infection strategy was significantly higher when based on mNGS than on empirical antibiotics (85% vs. 56.5%, P=0.004). Conclusion The mNGS test is superior to CMT for identifying clinically relevant pathogens, and provides valuable information for anti-infection strategies in allo-HSCT recipients. Additionally, attention should be paid to immune events in patients with negative mNGS results.

Abstract
Organic semiconductor single crystals (OSSCs) are ideal materials for studying the intrinsic properties of organic semiconductors (OSCs) and constructing high-performance organic field-effect transistors (OFETs). However, there is no general method to rapidly prepare thickness-controllable and uniform single crystals for various OSCs. Here, inspired by the recrystallization (a spontaneous morphological instability phenomenon) of polycrystalline films, a spatial confinement recrystallization (SCR) method is developed to rapidly (even at several second timescales) grow thickness-controllable and uniform OSSCs in a well-controlled way by applying longitudinal pressure to tailor the growth direction of grains in OSCs polycrystalline films. The relationship between growth parameters including the growth time, temperature, longitudinal pressure, and thickness is comprehensively investigated. Remarkably, this method is applicable for various OSCs including insoluble and soluble small molecules and polymers, and can realize the high-quality crystal array growth. The corresponding 50 dinaphtho[2,3-b:2″,3″-f]thieno[3,2-b]thiophene (DNTT) single crystals coplanar OFETs prepared by the same batch have the mobility of 4.1 ± 0.4 cm2 V-1 s-1 , showing excellent uniformity. The overall performance of the method is superior to the reported methods in term of growth rate, generality, thickness controllability, and uniformity, indicating its broad application prospects in organic electronic and optoelectronic devices.

Abstract
Immunogenic cell death (ICD) is a unique phenomenon that can trigger comprehensive, adaptive immune responses through damage-associated molecular patterns, offering a promising avenue for tumor immunotherapy. However, the role of ICD-related genes and their correlation with endometrial carcinoma (EC), the most prevalent gynecologic malignancy, remains unclear. This study examined genetic, transcriptional, and clinical data of EC obtained from the Cancer Genome Atlas database. Unsupervised clustering analysis was utilized to identify distinct ICD clusters based on the expression of ICD-related genes. Regarding the different clusters, their survival analysis, assessment of the immune microenvironment, immune cell infiltration, immune checkpoint analysis, and tumor mutation burden analysis were performed. Furthermore, an ICD risk signature was established using univariate Cox regression and least absolute shrinkage and selection operator analysis. The Chi-square test was employed to investigate the relationship between the ICD score and clinical features. Multiple computational analytical tools were used to assess immune annotation, somatic mutations, tumor mutation burden, and response to immunotherapy and chemotherapy drugs in different ICD score groups. Two ICD clusters were identified, indicating that the ICD-high cluster was associated with improved prognosis, abundant immune cell infiltration, and enrichment of pathways related to immunologic activation. Moreover, the ICD risk signature showed predictive value for the immune microenvironment, immunotherapy response, chemotherapy susceptibility, and prognosis in EC. Our findings offer novel insights into personalized treatment strategies for EC patients.

Abstract
The two most commonly used airway management techniques during general anaesthesia are supraglottic airway devices and tracheal tubes. In older patients undergoing elective non-cardiothoracic surgery under general anaesthesia with positive pressure ventilation, we hypothesised that a composite measure of in-hospital postoperative pulmonary complications would be less frequent when a supraglottic airway device was used compared with a tracheal tube. We studied patients aged ≥ 70 years in 17 clinical centres. Patients were allocated randomly to airway management with a supraglottic airway device or a tracheal tube. Between August 2016 and April 2020, 2900 patients were studied, of whom 2751 were included in the primary analysis (1387 with supraglottic airway device and 1364 with a tracheal tube). Pre-operatively, 2431 (88.4%) patients were estimated to have a postoperative pulmonary complication risk index of 1-2. Postoperative pulmonary complications, mostly coughing, occurred in 270 of 1387 patients (19.5%) allocated to a supraglottic airway device and 342 of 1364 patients (25.1%) assigned to a tracheal tube (absolute difference -5.6% (95%CI -8.7 to -2.5), risk ratio 0.78 (95%CI 0.67-0.89); p < 0.001). Among otherwise healthy older patients undergoing elective surgery under general anaesthesia with intra-operative positive pressure ventilation of their lungs, there were fewer postoperative pulmonary complications when the airway was managed with a supraglottic airway device compared with a tracheal tube.

Abstract
OBJECTIVE To investigate whether the expression of triple motif protein 19/38 (TRIM19/38) mRNA in peripheral blood mononuclear cells (PBMCs) of HBeAg-negative chronic hepatitis B virus (HBV) carriers is associated with the response to pegylated interferon alpha (peg-IFN-α) treatment and HBsAg clearance. METHODS In this prospective study, HBeAg-negative chronic HBV carriers treated with peg-IFN-α completed 48 weeks of follow-up. After treatment with peg-IFN-α, the patients were divided into responders (R group) and nonresponders (NR group) according to the changes in HBV DNA and HBsAg levels at week 48 of treatment. According to whether serum HBsAg loss or seroconversion occurred, the patients were divided into a serological response group (SR group) and a nonserological response group (NSR group). The level of TRIM19/38 mRNA in PBMCs was detected by real-time fluorescence quantitative PCR. The diagnostic performance of TRIM19/38 was analysed by calculating the receiver operating characteristic (ROC) curve and area under the ROC curve (AUC). RESULTS 43 HBeAg-negative chronic HBV carriers, 35 untreated CHB patients and 19 healthy controls were enrolled in this study. We found that TRIM19/38 mRNA levels were significantly lower in untreated CHB patients than in healthy controls. In HBeAg-negative chronic HBV carriers who underwent prospective follow-up, TRIM19/38 mRNA levels were negatively correlated with HBV DNA and ALT at baseline. Among the patients treated with peg-IFN-α, 16 patients achieved a treatment response (R group) and 27 patients did not achieve a treatment response (NR group). Compared with baseline, HBsAg levels in the R group decreased significantly at 12 and 24 weeks of treatment; at the early stage of peg-IFN-α treatment, the dynamic changes in TRIM19/38 mRNA levels in the R and NR groups were different, and the TRIM19/38 mRNA levels in the R group were significantly higher than those in the NR group, especially at 24 weeks of treatment. ROC curve analysis showed that the changes in mRNA levels of TRIM19 and TRIM38 predicted the treatment response, with AUCs of 0.694 and 0.757, respectively. Among the patients treated with peg-IFN-α, 11 patients achieved a serological response (SR group) and 32 patients did not achieve a serological response (NSR group). Compared with baseline, HBsAg levels in the SR group decreased significantly at 12 and 24 weeks of treatment; TRIM19/38 mRNA levels were significantly higher in the SR group than in the NSR group at week 24. CONCLUSION The higher level of TRIM19/38 mRNA in PBMCs of HBeAg-negative chronic HBV carriers may be related to the early treatment effect of peg-IFN-α and HBsAg clearance. TRIM19 and TRIM38 have clinical significance in predicting virological response and guiding treatment regimens.

Abstract
PURPOSE We aimed to investigate the impacts of age, gender, and race on aortic dimensions in healthy adults. METHODS We analyzed data from 3 large population-based sample studies, including Chinese Echocardiographic Measurements in Normal Chinese Adults, Japanese the Normal Values for Echocardiographic Measurements Project, and European Normal Reference Ranges for Echocardiography, to compare the two-dimensional echocardiography-derived aortic diameters at different levels and to explore the effects of age, gender, and race on aortic measurements. We also compared the values corrected by body surface area (BSA) or height. RESULTS The results are as follows: (1) Aortic diameters showed positive correlations with age (r=0.12-0.42, P<0.05), and there were significant inter-age group differences before and after indexing to BSA (P<0.05); (2) Men had greater measurements of aortic diameters than women, with the differences being the same when indexed to height. However, indexing to BSA reversed the differences; (3) The aortic diameters at annulus (Ao-a) and sinus (Ao-s) levels were very close with minor differences between the Chinese and Japanese regardless of whether BSA was used for correction; and (4) The aortic measurements at Ao-s and proximal ascending aorta (Ao-asc) levels in the Chinese were significantly lower than in the Europeans for both genders, with the differences remaining the same even after indexing to BSA or height (P<0.05). CONCLUSION Aortic dimensions vary with age and gender, and there are significant differences between races or ethnicities even when stratified by gender and age. The indexation by BSA or height cannot eliminate these differences. Therefore, age-specific, gender-specific, race-specific, and nationality-specific reference values may be more appropriate at present for clinical practice to avoid misdiagnosis and misclassification of aortic dilation.

Abstract
Our previous data confirmed that 1,8-Cineole had an antihypertensive effect in animal models. However, it is unclear whether antihypertension is dependent on the protective effect of 1,8-Cinceole on endothelial function and structure. At present, the purpose was to investigate the protective effects of 1,8-Cineole on vascular endothelial tissue in hypertensive rats and human umbilical vein endothelial cells (HUVECs). Our results showed that 1,8-Cineole significantly reduced the blood pressure and improved the vascular endothelial lesion, attenuated vascular oxidative stress and inflammation induced by L-nitroarginine methyl ester hydrochloride (L-NAME) in rats. Pretreatment with 1,8-Cineole was able to inhibit the increase in malondialdehyde (MDA) and reactive oxygen species (ROS) induced by L-NAME, and increased the release and expression of superoxide dismutase (SOD) and nitric oxide (NO). In addition, 1,8-Cineole also reversed the increase of autophagy-associated protein LC3Ⅱ/LC3Ⅰ and the decrease of P62 in vivo and in vitro respectively. There was a synergistic effect between PI3K agonists and drugs, while PI3K inhibitors blocked the efficacy of 1,8-Cineole. The addition of autophagy inhibitor CQ increases the expression of eNOS. Taken together, our results indicate that 1,8-Cineole has potential beneficial promising antihypertension depending on the integrity of vascular endothelial structure and function induced by L-NAME, and the mechanism involves ameliorating autophagy by regulatiing of PI3K/mTOR.

Abstract
PURPOSE The aim of this study was to explore how family resilience and individual resilience reduce perceived stress and psychological distress in young female breast cancer survivors with fertility intention. METHODS From June 2020 to June 2021, female breast cancer survivors were selected from the cancer centers of 10 tertiary Level A general hospitals in five cities of Sichuan Province. The survivors completed the Chinese versions of the Family Resilience Assessment Scale, Connor-Davidson Resilience Scale, Perceived Stress Scale, and a self-report distress thermometer. A multiple mediation effects test and structural equation modeling were used to explore the relationships among family resilience, individual resilience, perceived stress, and psychological distress. RESULTS The direct effect of family resilience on perceived stress was β = -0.320 (95% confidence interval -0.365, -0.271, P < 0.01). The direct effect of family resilience on psychological distress was β = -0.263 (95% confidence interval -0.363, -0.153, P < 0.001). The direct effect of family resilience on individual resilience was β = 0.593 (95% confidence interval 0.542-0.640, P < 0.001). The indirect effect of family resilience on psychological distress was β = -0.322 (95% confidence interval -0.373, -0.274, P < 0.001). Both perceived stress and individual resilience mediated the relationship between family resilience and psychological distress. Furthermore, a partial mediating effect of perceived stress and individual resilience on family resilience and psychological distress was observed. CONCLUSION Young female breast cancer survivors in China experience moderate levels of psychological distress.

Abstract
Acute graft-versus-host disease (aGVHD) is a severe complication of allogeneic hematopoietic stem cell transplantation. Hematopoietic dysfunction accompanied by severe aGVHD, which may be caused by niche impairment, is a long-standing clinical problem. However, how the bone marrow (BM) niche is damaged in aGVHD hosts is poorly defined. To comprehensively address this question, we employed a haplo-MHC-matched transplantation aGVHD murine model and performed single-cell RNA sequencing of non-hematopoietic BM cells. Transcriptional analysis showed that BM mesenchymal stromal cells (BMSCs) were severely affected with a reduction in cell ratio, abnormal metabolism, compromised differentiation potential and defective hematopoietic supportive function, which were validated by functional assays. We found that ruxolitinib, a selective JAK1/2 inhibitor, ameliorated aGVHD-related hematopoietic dysfunction through direct effect on recipient BMSCs, resulting in improved proliferation ability, adipogenesis/osteogenesis potential, mitochondrial metabolism capacity and crosstalk with donor-derived hematopoietic stem/progenitor cells. By inhibiting the JAK2/STAT1 pathway, ruxolitinib maintained long-term improvement of aGVHD BMSC function. Additionally, ruxolitinib pretreatment in vitro primed BMSCs to better support donor-derived hematopoiesis in vivo. These observations in the murine model were validated in patient samples. Overall, our findings suggest that ruxolitinib can directly restore BMSC function via JAK2/STAT1 pathway and in turn, improve the hematopoietic dysfunction caused by aGVHD.

Abstract
We present a 55-year-old man with chest tightness and dyspnoea after activity lasting for 2 months who was diagnosed with single coronary artery (SCA) and presented with dilated cardiomyopathy (DCM) with the c.1858C > T mutation in the SCN5A gene. The computed tomography coronary angiogram (CTCA) showed congenital absence of the right coronary artery (RCA), and the right heart was nourished by the left coronary artery branch with no apparent stenosis. Transthoracic echocardiography (TTE) revealed enlargement of the left heart and cardiomyopathy. Cardiac magnetic resonance imaging (CMR) revealed DCM. Genetic testing showed that the c.1858C > T variant of the SCN5A gene could lead to Brugada syndrome and DCM. SCA is a rare congenital anomaly of the coronary anatomy, and this case reported as SCA accompanied by DCM is even rarer. We present a rare case of a 55-year-old man with DCM with the c.1858C > T (p. Arg620Cys)/c.1008G > A (p.(Pro336=) variant of the SCN5A gene, congenital absence of RCA, and c.990_993delAACA (p. Asp332Valfs*5) variant of the APOA5 gene. To our knowledge, this is the first report of DCM combined with the SCN5A gene mutation in SCA after searching the PubMed, CNKI and Wanfang databases.

Abstract
BACKGROUND Anti-hepatitis B virus (HBV) treatment uses tenofovir disoproxil fumarate (TDF) along with Pegylated-interferon-alpha (Peg-IFN-α), which is more effective than TDF/Peg-IFN-α monotherapy. We have previously shown that interleukin-1beta (IL-1β) is related to the effectiveness of IFN-α treatment in chronic hepatitis B (CHB) patients. The aim was to investigate the expression of IL-1β in CHB patients treated with Peg-IFN-α combination with TDF and TDF/Peg-IFN-α monotherapy. METHODS Huh7 cells infected with HBV were stimulated by Peg-IFN-α and/or Tenofovir (TFV) for 24h. A single-center cohort study of prospective recruitment of CHB patients: untreated CHB (Group A), TDF combined with Peg-IFN-α therapy (Group B), Peg-IFN-α monotherapy (Group C), TDF monotherapy (Group D). Normal donors served as controls. The clinical datas and blood of patients were collected at 0, 12, and 24 weeks. According to the early response criteria, Group B and C were divided into two subgroups: the early response group (ERG) and the non-early response group (NERG). Stimulation of HBV-infected hepatoma cells with IL-1β to validate the antiviral activity of IL-1β. To test the blood sample, cell culture supernatant, and cell lysates and to assess the expression of IL-1β and HBV replication levels in various treatment protocols, Enzyme-Linked Immunosorbent Assay (ELISA) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) were used. SPSS 26.0 and GraphPad Prism 8.0.2 software were used for statistical analysis. P values < 0.05 was considered to be statistically significant. RESULTS In vitro experiments, Peg-IFN-α plus TFV treatment group expressed higher IL-1β and inhibited HBV more effectively than monotherapy. Finally, 162 cases were enrolled for observation (Group A (n = 45), Group B (n = 46), Group C (n = 39), and Group D (n = 32)), and normal donors (n = 20) were enrolled for control. The early virological response rates of Group B, C, and D were 58.7%, 51.3%, and 31.2%. At 24 weeks, IL-1β in Group B(P = 0.007) and C(P = 0.034) showed higher than at 0 week. In Group B, the IL-1β showed an upward trend at 12w and 24w in the ERG. IL-1β significantly reduced HBV replication levels in hepatoma cells. CONCLUSION The increased expression of IL-1β may enhance the efficacy of TDF combined with Peg-IFN-α therapy in achieving an early response for CHB patients.

AbstractGenetic heterogeneity poses a great challenge to the understanding and management of acute myeloid leukemia (AML). Knowledge of the IKZF1 mutation in AML specifically is extremely limited. In a previous work, we described the distribution pattern of IKZF1 mutation in AML, but its clinical impact has remained undefined due to the limited number of cases. Herein, we attempt to answer this question in one relatively large cohort covering 522 newly diagnosed AML patients. A total of 26 IKZF1 mutations were found in 20 AML patients (20/522, 3.83%). This condition has a young median age of onset of morbidity (P = 0.032). The baseline characteristics of IKZF1-mutated and wild-type patients were comparable. IKZF1 mutation showed significant co-occurrences with CEBPA (P < 0.001), SF3B1 (P < 0.001), and CSF3R (P = 0.005) mutations, and it was mutually exclusive with NPM1 mutation (P = 0.033). Although IKZF1-mutated AML was more preferably classified into the intermediate-risk group (P = 0.004), it showed one inferior complete remission rate (P = 0.032). AML with high burden of IKZF1 mutation (variant allele frequency > 0.20) showed relatively short overall survival period (P = 0.012), and it was an independent factor for the increased risk of death (hazard ratio, 6.101; 95% CI 2.278–16.335; P = 0.0003). In subgroup analysis, our results showed that IKZF1 mutation conferred poor therapeutic response and prognosis for SF3B1-mutated AML (P = 0.0017). We believe this work improves our knowledge of IKZF1 mutation.

Abstract
Pediatric-inspired chemotherapy significantly improves survival for adolescent and adult patients with acute lymphoblastic leukemia (ALL). However, the benefits over allogeneic hematopoietic stem cell transplantation (allo-HSCT) remain unclear. To compare clinical outcomes between pediatric-inspired chemotherapy and allo-HSCT in consolidation therapy of adolescent and adult Philadelphia chromosome-negative (Ph-neg) ALL in first complete remission (CR1), related studies from MEDLINE, Embase, and Cochrane Controlled Register of Trials updated to July 2022 were searched. A total of 13 relevant trials including 3161 patients were included in the meta-analysis. Compared with allo-HSCT, pediatric-inspired chemotherapy achieved better OS (hazard risk (HR), 0.53; 95% confidence interval (CI), 0.41 to 0.68) and DFS (HR, 0.64; 95% CI, 0.48 to 0.86), with a significant reduction in NRM (risk ratio (RR), 0.30; 95% CI, 0.18 to 0.51), but no difference in the relapse rate (RR, 1.13; 95% CI, 0.93 to 1.39). When only studies based on intention-to-treat analysis were included, pediatric-inspired chemotherapy consistently conferred a survival advantage. In subgroup analyses, patients with baseline high-risk features demonstrated similar OS and DFS between pediatric-style chemotherapy and allo-HSCT, while pediatric-style chemotherapy had an OS and DFS advantage in standard-risk subgroup. Particularly, patients with positive minimal residual disease (MRD) achieved better OS and DFS if proceeded to allo-HSCT.

Abstract
OBJECTIVES To assess reproductive concerns in patients of childbearing age with breast cancer and examine the relationship between self-disclosure, resilience and reproductive concerns. DESIGN Cross-sectional survey. SETTING Five tertiary first-class general hospitals in Sichuan Province, Southwest China. PARTICIPANTS A total of 319 patients with breast cancer of reproductive age who were hospitalised in the breast oncology department participated in this study. MAIN OUTCOME MEASURES Primary outcomes were the relationship between resilience, self-disclosure and reproductive concerns, and mediating effect analyses. Secondary outcomes included the status of reproductive concerns. RESULTS The model accounted for 39.1% of the variance in reproductive concerns. Self-disclosure had a direct negative effect on reproductive concerns (β= -0.371, p=0.001). Resilience had a direct negative effect on reproductive concerns (β= -0.349, p=0.001) and a direct positive effect on self-disclosure (β=0.507, p=0.001). Furthermore, self-disclosure partially mediated the relation between resilience and reproductive concerns (β= -0.177; SE=0.041; 95% CI -0.261 to -0.104; p<0.050), with a bootstrap of 10 000 samples. CONCLUSIONS The findings suggest that self-disclosure and resilience may ease reproductive concern. Therefore, self-disclosure education and resilience-oriented interventions should be provided to patients of childbearing age with breast cancer, to reduce reproductive concerns.

Abstract
High-temperature Daqu is an important saccharifying fermenting starter for brewing Jiang-flavored Baijiu. This paper analyzed the diversity characteristics of bacterial communities of Jiang-flavored Daqu (JFDQ) with seasonal changes through Illumina HiSeq sequencing and multivariate statistical methods. Results showed that 21 phyla, 529 genera, and 47 core bacterial genera were identified from the 48 composite samples. Among them, eight functional genera were only found in the summer-produced Daqu (Propionigenium, etc.). Pantoea, Bacillus, Lentibacillus, and Oceanobacillus, respectively, served as the representative functional bacterial genera of the four seasons. Functional prediction analysis showed that Amino acid metabolism Carbohydrate metabolism, Lipid metabolism, Metabolism of cofactors and vitamins, and Nucleotide metabolism (relative abundance > 1%) were the most critical microbial functions in JFDQ, and these key enzymes involved in acetoin biosynthesis, and acetyl-CoA biosynthesis were more abundant in the summer than in the winter. The functional microorganisms community in this paper would provide valuable suggestions about the seasonal production of JFDQ, guiding the Baijiu brewing processes.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common types of cancer worldwide, which leads to more than 10% of cancer-related deaths. Metabolism reprogramming presents as a pivotal event in cancer initiation and progression through enhancing aerobic glycolysis and anabolic metabolism. However, the underlying regulatory mechanisms in GC remain unknown. METHODS VAL was identified by bioinformatics analyses in GC. Cell-based assays and mouse model illustrate the role of VAL in GC. RNA pull-down, immunoprecipitation assay and Western blot elucidate the interaction between VAL and PKM2. Pyruvate kinase activity, ECAR and OCR were measured to validate aerobic glycolysis of GC cells. RESULTS Long non-coding RNA (lncRNA) VAL is significantly upregulated in GCs and indicates poor prognosis. Functional assays showed that VAL promotes GC malignant progression. Mechanistically, VAL strengthens the enzymatic activity of PKM2 and aerobic glycolysis of GC cells through directly binding with PKM2 to abrogate the PKM2-Parkin interaction, and to suppress Parkin-induced polyubiquitination of PKM2. In addition, glucose starvation induces VAL expression to enhance this process. CONCLUSIONS Our study provides an insight into an lncRNA-dependent regulation on the enzymatic activity of PKM2, and suggests a potential of targeting VAL or PKM2 as promising biomarkers in GC diagnosis and treatment.

Abstract
The mitochondria represent a potential target for the treatment of triple-negative breast cancer (TNBC) and shikonin (SK) has shown remarkable therapeutic effects on TNBC. Herein, it is found that SK possesses potent inhibitory effects on mitochondrial biogenesis via targeting polymerase gamma (POLG). However, its application is restricted by its poor aqueous solubility and stability, and therefore, a biomimetic micelle to aid with tumor lesion accumulation and mitochondria-targeted delivery of SK is designed. A folic acid (FA) conjugated polyethylene glycol derivative (FA-PEG-FA) is inserted onto the external membranes of red blood cells (FP-RBCm) to prepare a "right-side-out" RBCm-camouflaged cationic micelle (ThTM/SK@FP-RBCm). Both FP-RBCm coating and a triphenylphosphine (TPP) moiety on the periphery of micelles contribute to tumor lesion distribution, receptor-mediated cellular uptake, and electrostatic attraction-dependent mitochondrial targeting, thereby maximizing inhibitory effects on mitochondrial biosynthesis in TNBC cells. Intravenous administration of ThTM/SK@FP-RBCm leads to profound inhibition of tumor growth and lung metastasis in a TNBC mouse model with no obvious toxicity. This work highlights the mitochondria-targeted delivery of SK using a "right-side-out" membrane-camouflaged micelle for the inhibition of mitochondrial biogenesis and enhanced therapeutic effects on TNBC.

Abstract
Objective: To observe the effect of silicon dioxide (SiO(2)) on the polarization of alveolar macrophages (AMs) , and to explore the expressions and the significance of signal transducer and activator of transcription-6 (STAT-6) /Krüppel-like factor-4 (KLF-4) /peroxisome proliferators-activated receptors-γ (PPAR-γ) signaling molecules in AMs. Methods: In November 2020, C57BL/6 mice were randomly divided into crystalline SiO(2) group and normal saline (NS) group, and 12 mice in each group. Mice were intratracheally instillated with 100 μl crystalline SiO(2) suspension (20 mg/ml) or 100 μl NS, and were sacrificed after 28 days. Masson staining was used to observe the degree of pulmonary fibrosis of mice and hydroxyproline (HYP) level were assessed. The proportions of M1-typed and M2-typed AMs in bronchoalveolar lavage fluid (BLAF) were analyzed by flow cytometry. The mRNA relative expression levels of inducible nitric oxide synthase (iNOS) , arginidase-1 (Arg-1) , interleukin (IL) -1β, tumor necrosis factor-α (TNF-α) , IL-6, IL-10, transforming growth factor-β (TGF-β) , STAT-6, KLF-4 and PPAR-γ were detected by real-time fluorescence quantitative PCR. Activities of iNOS and Arg-1, as well as contents of IL-1β, TNF-α, IL-6, IL-10 and TGF-β were assessed by the enzyme-linked immunosorbent. The protein relative expression levels of phosphorylation-signal transducer and activator of transcription-6 (p-STAT-6) , KLF-4 and PPAR-γ were evaluated by immunofluorescence. Results: After 28 days of treatment, the structure of the lung tissue of the mice was destroyed, and the deposition of collagen was significantly increased in the crystalline SiO(2) group. Compared with NS group, HYP level of lung tissue in crystalline SiO(2) group were increased, the proportion of M2-typed AMs in crystalline SiO(2) group was increased, the proportion of M1-typed AMs in crystalline SiO(2) group was decreased, the mRNA relative expressions and contents of Arg-1, IL-10, TGF-β in crystalline SiO(2) group were significantly increased, the mRNA relative expressions and contents of iNOS, IL-1β, TNF-α, IL-6 in crystalline SiO(2) group were significantly decreased, the mRNA of STAT-6, KLF-4, PPAR-γ and the protein relative expression levels of p-STAT-6, KLF-4, PPAR-γ were significantly increased in crystalline SiO(2) group, and the the differences were statistically significant (P<0.05) . Conclusion: Crystalline SiO(2) may mediate the process of pulmonary fibrosis through promote AMs polarization toward M2-typed by activating the STAT-6/KLF-4/PPAR-γ signaling pathway.

Abstract
Objective: To compare decentration and tilt tolerances between continuous range intraocular lens (IOL) and bifocal IOL in myopia during the early stages post intraocular implantation. Method: A retrospective cohort study was conducted using follow-up data of 145 patients (145 eyes) who underwent phacoemulsification combined with IOL implantation in the Eye & ENT Hospital of Fudan University from January 2018 to December 2020. According to whether the axial length was less than 24.5 mm, patients were divided into non-myopic and myopic groups. According to IOL type, patients were divided into extend depth of focus (EDOF) ZXR00 IOL group (myopic 38 eyes, non-myopic 41 eyes) and bifocal ZMB00 IOL group (myopic 23 eyes, non-myopic 43 eyes). The distance and near visual acuity (log of the minimum angle of resolution visual acuity), IOL tilt and decentration, intraocular high-order aberration (HOA), coma, trefoil, spherical aberrations, modulation transfer function (MTF), as well as VF-14 index and the incidence of dysphotopsia were compared between the 2 groups at 3 months after surgery. Statistics were performed using Student's t-test, χ2 test, Pearson correlation analysis and multiple linear regression analysis. Results: In either the myopic or non-myopic group, no significant differences were found in age, gender, eye laterality, axial length and IOL degree between eyes with the two different types of IOLs (all P>0.05). At 3 months after surgery, there was no significant difference in uncorrected and best-corrected distance visual acuity between the ZXR00 IOL group and the ZXR00 IOL group, while uncorrected near visual acuity was better in the ZMB00 IOL group than the ZXR00 IOL group (t=10.41, P<0.01). The total postoperative IOL decentration in the ZXR00 IOL group and ZMB00 IOL group in myopic eyes were (0.32±0.17) and (0.38±0.16) mm, respectively, which were greater than those in non-myopic eyes [(0.22±0.12), (0.28±0.12) mm; t=3.16, 2.57; both P<0.05]. However, there were no significant differences in IOL tilt between myopic and non-myopic eyes in the 2 groups (both P>0.05). There were no significant differences in postoperative IOL tilt and decentration between the 2 groups regardless of myopia or non-myopia (all P>0.05). In myopic eyes, HOA, coma aberration and spherical aberration in the ZXR00 IOL group were significantly lower than those in the ZMB00 IOL group, while the total ocular MTF (38.15±10.12) was significantly higher than that in the ZMB00 IOL group (30.46±10.53) (all P<0.05). Pearson correlation analysis and multiple linear regression analysis showed a positive correlation between postoperative HOA and both IOL tilt and decentration in the ZMB00 IOL group (r=0.627, 0.726; β=0.446, 0.587; all P<0.01). However, no such relationship was found in the ZXR00 IOL group (all P>0.05). In myopic eyes, when the IOL tilt aberration and decentration were greater than the median, the HOAs in the ZXR00 IOL group [(0.33±0.14), (0.27±0.11) μm] were lower than those in the ZMB00 IOL group [(0.88±0.56), (0.96±0.45) μm], while the total ocular MTF (42.87±10.97, 40.22±9.30) were higher than those in the ZMB00 IOL group (25.02±8.99, 29.87±10.19) (all P<0.05). In myopic eyes, the proportion of patients with visual interference symptoms in the ZXR00 IOL group [42.11% (16/38)] was significantly lower than that in the ZMB00 IOL group [78.26%(18/23), χ²=7.59, P<0.05]. Conclusion: During the early stages after IOL implantation in myopic eyes, EDOF IOL is more tolerant to decentration and tilt than bifocal IOL.

Abstract
Introduction and importance: Tuberculosis is one of the leading causes of mortality in many developing countries. Female genital tuberculosis, a relatively uncommon form of tuberculosis, is critically challenging to diagnose due to its insidious and non-typical presentations. Case presentation Herein, we present with an asymptomatic infertile woman with persistently high CA-125 passed undiagnosed until laparoscopy unveiled the diagnosis of TB. Clinical discussion In this study, we highlight the diagnostic complexities in female genital tuberculosis and demonstrate the value of the CA-125 increase in prompting the suspicion of tuberculosis in the appropriate clinical context. Conclusion Given the considerably large number of individuals with tuberculosis in China, we strongly recommend routine tuberculosis screening in women seeking infertility care in China. Female genital tuberculosis is difficult to diagnose early due to its rarity and insidious symptoms. Persistent elevation of CA-125 may indicate the presence of tuberculosis in rare occasions. Performing tuberculosis screening routinely for infertile womenin tuberculosis prevailing regions is recommended.

Abstract
Objective: To investigate the influence of residual astigmatism on the postoperative visual acuity in cataract patients with implantation of an extended depth of focus intraocular lens (IOL). Methods: Retrospective cohort study. A total of 56 eyes of 56 cataract patients who underwent phacoemulsification combined with extended depth of focus IOL implantation from January 2019 to December 2020 at Eye & ENT Hospital of Fudan University were included. There were 29 males and 27 females in all patients, and the age was (65±9) years. Patients were divided into two groups according to their postoperative residual astigmatism: low astigmatism group (<0.75 D, 28 eyes) and high astigmatism group (0.75 to 1.50 D, 28 eyes). At 3 months after surgery, measurements were completed, including postoperative uncorrected distance (5 m) visual acuity, uncorrected intermediate (80 cm) visual acuity, uncorrected near (40 cm) visual acuity, best corrected visual acuity (all the visual acuity was converted to the logarithm of the minimum angle of resolution visual acuity), defocus curves, quick contrast sensitivity function, wavefront aberration, and VF-14 questionnaire scores. The independent samples t-test and Mann-Whitney U test were used for data analysis. Results: The low astigmatism group and high astigmatism group's uncorrected distance visual acuity [M (Q1, Q3)] were 0.05 (-0.06, 0.10), 0.08 (0.00, 0.22), their uncorrected intermediate visual acuity were 0.11 (0.00, 0.20), 0.14 (0.10, 0.21), their uncorrected near visual acuity were 0.28 (0.20, 0.32), 0.26 (0.20, 0.30), and their best corrected visual acuity were 0.17 (0.05, 0.30), 0.14 (0.04, 0.22), respectively. The differences were not statistically significant (all P>0.05). No significant difference was found in the defocus curves from +1.00 to -4.00 D, at intervals of +0.50 D, between the two groups (all P>0.05). No significant difference was found in the quick contrast sensitivity of low, middle and high frequency of dark vision between the low astigmatism group and high astigmatism group (all P>0.05), and the area under Log contrast sensitivity function of the two groups were 0.87±0.28 and 0.77±0.30 (P>0.05). The total whole-eye aberrations were 0.59±0.18 and 0.74±0.51, and the total higher-order aberrations were 0.30±0.13 and 0.37±0.25 in the two groups at 4.0-mm pupil diameter. The differences were not statistically significant when the total whole-eye aberration, total higher-order aberration, coma, cloverleaf aberration, and spherical aberration were compared (all P>0.05). The differences of the total VF-14 visual scores, near visual acuity scores and the distance visual acuity scores of the two groups were not statistically significant (all P>0.05). Conclusion: Cataract patients with residual postoperative astigmatism 0.75 to 1.50 D can obtain as good visual quality as those with postoperative residual astigmatism<0.75 D after implantation of an extended depth of focus IOL.

Abstract
AIMS AND OBJECTIVES This study examines the effects of family beliefs and family strength on individual resilience and quality of life among young breast cancer survivors and determines whether family strength mediates the effect of family beliefs on individual resilience and quality of life. BACKGROUND Family beliefs and family strength are meaningful protective factors that help individuals maintain physical and mental health. However, few studies have explored their impact on individual resilience and quality of life. DESIGN This study was conducted using a cross-sectional survey with a three-stage, stratified, convenience sampling approach following the STROBE guideline. METHODS From August 2020 to May 2021, participants completed the shortened Chinese version of the Connor-Davidson Resilience Scale, the Chinese version of the Family Beliefs Scale, the Family Strength Scale and the Functional Assessment of Cancer Therapy-Breast scale. Structural equation modelling and multiple mediation effects test were used to explore the relationships among family beliefs, family strength, individual resilience and quality of life. RESULTS The final model accounted for 44.5% and 78.1% of the total variance of individual resilience and quality of life, respectively. Family beliefs had an indirect effect on both individual resilience and quality of life through family strength. Family strength had a direct effect on individual resilience and had both a direct and an indirect effect on quality of life. Family strength mediated the correlations of family beliefs with individual resilience and quality of life. CONCLUSION Mobilising family resources to establish healthy family beliefs and exert positive family strength will help increase young breast cancer survivors' individual resilience and improve quality of life. RELEVANCE TO CLINICAL PRACTICE This study confirms the importance for clinical nursing practice to mobilise family resources and develop interventions centred on family beliefs and family strength.

Abstract
Acute graft-versus-host disease (aGvHD) is the most common complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and significantly linked with morbidity and mortality. Although much work has been engaged to investigate aGvHD pathogenesis, the understanding of alloreactive T-cell activation remains incomplete. To address this, we studied transcriptional activation of carbohydrate, nucleotide, tricarboxylic acid (TCA) cycle, and amino acid metabolism of T cells before aGvHD onset by mining the Gene Expression Omnibus (GEO) datasets. Glycolysis had the most extensive correlation with other activated metabolic sub-pathways. Through Pearson correlation analyses, we found that glycolytic activation was positively correlated with activated CD4 memory T-cell subset and T-cell proliferation and migration. T-cell receptor (TCR), mechanistic target of rapamycin complex 1 (mTORC1), myelocytomatosis oncogene (MYC) signaling pathways and E2F6 might be “master regulators” of glycolytic activity. aGvHD predictive model constructed by glycolytic genes (PFKP, ENO3, and GAPDH) through logistic regression showed high predictive and discriminative value. Furthermore, higher expressions of PFKP, ENO3, and GAPDH in alloreactive T cells were confirmed in our pre-aGvHD patient cohort. And the predictive value of the aGvHD risk model was also validated. In summary, our study demonstrated that glycolytic activation might play a pivotal function in alloreactive T-cell activation before aGvHD onset and would be the potential target for aGvHD therapy.
