Abstract
The trophoblast epithelial-to-mesenchymal transition (EMT) is a procedure related to embryo implantation, spiral artery establishment and fetal-maternal communication, which is a key event for successful pregnancy. Inadequate EMT is one of the pathological mechanisms of recurrent miscarriage (RM). Whole-exome sequencing revealed that the mutation of bromodomain PHD-finger transcription factor (BPTF) was strongly associated with RM. In the present study, the effects of BPTF on EMT and the underlying mechanism were investigated. We found that the expression of BPTF in the villi of RM patients was significantly downregulated. Gene Ontology (GO) analysis revealed that BPTF participated in cell adhesion. The knockdown of BPTF prevented EMT and attenuated trophoblast invasion in vitro. BPTF activated Slug transcription by binding directly to the promoter region of the Slug gene. Interestingly, the protein levels of both Slug and BPTF were decreased in the villous cytotrophoblasts (VCTs) of RM villi. In conclusion, BPTF participates in the regulation of trophoblast EMT by activating Slug expression, suggesting that BPTF defects are an important factor in RM pathogenesis.

Abstract
The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron's electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties. We present results from a novel measurement of the neutron magnetic form factor using quasielastic scattering from the mirror nuclei ^{3}H and ^{3}He, where the nuclear effects are larger than for deuterium but expected to largely cancel in the cross-section ratios. We extracted values of the neutron magnetic form factor for low-to-modest momentum transfer, 0.6

Abstract
Interlaboratory agreement of viral load assays depends on the accuracy and uniformity of quantitative calibrators. Previous work demonstrated poor agreement of secondary cytomegalovirus (CMV) standards with nominal values. This study re-evaluated this issue among commercially produced secondary standards for both BK virus (BKV) and CMV, using digital polymerase chain reaction (dPCR) to compare the materials from three different manufacturers. Overall, standards showed an improved agreement compared to prior work, against nominal values in both log10 copies/mL and log10 international unit (IU)/mL, with bias from manufacturer-assigned nominal values of 0.0-0.9 log10 units (either copies or IU)/mL. Standards normalized to IU and those values assigned by dPCR rather than by real-time PCR (qPCR) showed better agreement with nominal values. The latter reinforces prior conclusions regarding the utility of using such methods for quantitative value assignment in reference materials. Quantitative standards have improved over the last several years, and the remaining bias from nominal values might be further reduced by universal implementation of dPCR methods for value assignment, normalized to IU. IMPORTANCE Interlaboratory agreement of viral load assays depends on accuracy and uniformity of quantitative calibrators. Previous work, published in JCM several years ago, demonstrated poor agreement of secondary cytomegalovirus (CMV) standards with nominal values. This study re-evaluated this issue among commercially produced secondary standards for both BK virus (BKV) and CMV, using digital polymerase chain reaction (dPCR) to compare the materials from three different manufacturers. Overall, standards showed an improved agreement compared to prior work, against nominal values, indicating a substantial improvement in the production of accurate secondary viral standards, while supporting the need for further work in this area and for the broad adaption of international unit (IU) as a reporting standard for quantitative viral load results.

Abstract
Granulosa cells are somatic cells located inside follicles that play a crucial role in the growth and development of follicles. Quercetin and tanshinone are two key monomers in traditional Chinese medicine that have antioxidant and anti-aging properties. The KGN cell apoptosis model caused by triptolide (TP) was employed in this work to investigate granulosa cell death and medication rescue. Quercetin and tanshinone therapy suppressed KGN cell death and oxidation while also regulating the expression of critical apoptosis and oxidation-related markers such as B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax). Further research revealed that the effects of Quercetin and Tanshinone were accomplished via deacetylation of FOXO3A in the cytoplasm and mitochondria via the SIRT1/SIRT3-FOXO3a axis. In summary, Quercetin and tanshinone protect KGN cells from apoptosis by reducing mitochondrial apoptosis and oxidation via the SIRT1/SIRT3-FOXO3a axis.

Abstract
The placenta plays a pivotal role in the maintenance of normal pregnancy, but how it forms, matures, and performs its function remains poorly understood. Here, we describe a novel mouse line (Prl3d1-iCre) that expresses iCre recombinase under the control of the endogenous prl3d1 promoter. Prl3d1 has been proposed as a marker for distinguishing trophoblast giant cells (TGCs) from other trophoblast cells in the placenta. The in vivo efficiency and specificity of the Cre line were analyzed by interbreeding Prl3d1-iCre mice with B6-G/R reporter mice. Through anatomical studies of the placenta and other tissues of Prl3d1-iCre/+; B6-G/R mouse mice, we found that the tdTomato signal was expressed in parietal trophoblast giant cells (P-TGCs). Thus, we report a mouse line with ectopic Cre expression in P-TGCs, which provides a valuable tool for studying human pathological pregnancies caused by implantation failure or abnormal trophoblast secretion due to aberrant gene regulation.

Abstract
Climate dictates wildfire activity around the world. But East and Southeast Asia are an apparent exception as fire-activity variation there is unrelated to climatic variables. In subtropical China, fire activity decreased by 80% between 2003 and 2020 amid increased fire risks globally. Here, we assessed the fire regime, vegetation structure, fuel flammability and their interactions across subtropical Hubei, China. We show that tree basal area (TBA) and fuel flammability explained 60% of fire-frequency variance. Fire frequency and fuel flammability, in turn, explained 90% of TBA variance. These results reveal a novel system of scrubland-forest stabilized by vegetation-fire feedbacks. Frequent fires promote the persistence of derelict scrubland through positive vegetation-fire feedbacks; in forest, vegetation-fire feedbacks are negative and suppress fire. Thus, we attribute the decrease in wildfire activity to reforestation programs that concurrently increase forest coverage and foster negative vegetation-fire feedbacks that suppress wildfire.

Abstract
Background Previous studies have investigated the relationship between nesfatin-1 level and polycystic ovary syndrome (PCOS). However, these studies have produced conflicting results. Thus, in this meta-analysis, we aimed to clarify the association between blood nesfatin-1 levels and PCOS, and the ability of nesfatin-1 as a biomarker in PCOS. Methods Meta-analysis was performed using STATA 12.0 software. We computed standard mean difference (SMD) and 95% confidence interval (CI) regarding the comparison of blood nesfatin-1 in patients with PCOS and controls. Results The present meta-analysis showed no significant difference in blood nesfatin-1 level between patients with PCOS and controls with a random effects model (SMD = 0.03; 95%CI: -0.71, 0.77; I2 = 97.1%, p value for Q test < 0.001). Subgroup analysis for different ethnicities reported no significant difference in blood nesfatin-1 level between patients with PCOS and controls in both Caucasian and Asian populations. Subgroup analysis for different sample types reported no significant difference in serum nesfatin-1 level between patients with PCOS and controls. Subgroup studies reported no significant difference in blood nesfatin-1 level between PCOS and controls in both obese and non-obese populations. Conclusion In conclusion, there is no significant relationship between blood nesfatin-1 levels and PCOS.

Abstract
BACKGROUND Fatty acid oxidation of cumulus-oocyte complex (COC) provides sufficient energy for oocyte maturation. But, the relationship between fatty acid oxidation and oxidative stress in aging follicles, as well as the effect of putrescine, is still unclear. METHODS The porcine COCs were randomly divided into four groups and cultured in in vitro maturation (IVM) medium with or without 1 mmol/L putrescine, with 50 μmol/L hydrogen peroxide (H2O2) or with 50 μmol/L H2O2 plus 1 mmol/L putrescine. Oocyte maturation was assessed by the first polar body extrusion. The expressions of genes involved in fatty acid oxidation were detected, and the mitochondrial function was analyzed by themembrane potential. RESULTS The maturation rate of oocyte was significantly lower in the H2O2 group when compared with the control group (P<0.001), and putrescine significantly increased this rate in the H2O2 plus putrescine group when compared with the H2O2 group (P<0.001). The expressions of LKB1, STRAD, ACC2, AMPKα1 and AMPKα2 mRNAs in cumulus cells (CCs) were significantly downregulated by H2O2 treatment, and partly rescued by putrescine addition (P<0.05-0.001). However, the changes of LKB1, STRAD, ACC2, AMPKα1 and AMPKα2 mRNAs in oocytes were inapparent. The mitochondrial membrane potential of CCs in the H2O2 group was significantly lower than that in the control group, while putrescine addition significantly increased the mitochondrial membrane potential (P<0.001). CONCLUSION The decrease of oocyte maturation due to oxidative stress is related with the decreased fatty acid oxidation, and putrescine may alleviate the COCs damage via improving fatty acid oxidation.

Abstract
Low acrosin activity (LAA) is associated with sperm function anomaly and poor outcomes of in vitro fertilization. In this study, we confirm that 993 semen samples with LAA had a reduced sperm motility and low in vitro fertilization rate in comparison with 1332 normal controls (NC). Proteomic comparison between 11 LAA and 11 NC sperm samples identified 35 upregulated and 99 downregulated proteins in the LAA group. Indeed, proteomic data showed that acrosome enzymes Spam1 and Acrosin were among the downregulated proteins in the LAA group, which was validated by quantitative PCR and immunefluorescent staining of sperm cells. The KEEG pathway analysis revealed a deficiency of GSH and Gln biosynthesis in LAA sperm cells. Immunofluorescent staining of sperms and quantitative PCR verified downregulation of GLUL and GCLC, the key enzymes for GSH and Gln biosynthesis. Moreover, the results of ELISA assay confirmed low levels of GSH and Gln in LAA sperm cells. Mechanistic studies showed that addition of 10 mM H2O2 to semen samples led to a significant reduction of acrosin activity and sperm motility, most possibly by triggering premature acrosome release. In contrast, the presence of 20 mM GSH blocked the oxidative effects of H2O2. Since GSH counteracts the oxidative stress and Gln participates in TCA cycling, their deficiency may affect the redox balance as well as energy production of sperm cells. These findings shed new light on the pathological mechanisms of infertility associated with LAA. Male infertility patients could benefit from GSH supplement by improvement of acrosin activity and other sperm functions.

Abstract
OBJECTIVE To investigate the spatial distribution characteristics of the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody, and to examine the correlation between the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody in Hunan Province in 2020, so as to provide insights into advanced schistosomiais control in the province. METHODS The epidemiological data of schistosomiasis in Hunan Province in 2020 were collected, including number of permanent residents in survey villages, number of advanced schistosomiasis patients, number of residents receiving serological tests and number of residents seropositive for anti-Schistosoma antibody, and the prevalence advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody were descriptively analyzed. Village-based spatial distribution characteristics of prevalence advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody were identified in Hunan Province in 2020, and the correlation between the revalence advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody was examined using Spearman correlation analysis. RESULTS The prevalence of advanced schistosomiasis was 0 to 2.72% and the seroprevalence of anti-Schistosoma antibody was 0 to 20.25% in 1 153 schistosomiasis-endemic villages in Hunan Province in 2020. Spatial clusters were identified in both the prevalence of advanced schistosomiasis (global Moran's I = 0.416, P < 0.01) and the seroprevalence of anti-Schistosoma antibody (global Moran's I = 0.711, P < 0.01) in Hunan Province. Local spatial autocorrelation analysis identified 98 schistosomiasis-endemic villages with high-high clusters of the prevalence of advanced schistosomiasis, 134 endemic villages with high-high clusters of the seroprevalence of anti-Schistosoma antibody and 36 endemic villages with high-high clusters of both the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody in Hunan Province. In addition, spearman correlation analysis showed a positive correlation between the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody (rs = 0.235, P < 0.05). CONCLUSIONS There were spatial clusters of the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody in Hunan Province in 2020, which were predominantly located in areas neighboring the Dongting Lake. These clusters should be given a high priority in the schistosomiasis control programs.

Abstract
AIM To evaluate the relationship between oesophageal hiatus surface area (OHSA) and gastro-oesophageal reflux disease (GERD). MATERIALS AND METHODS Patients who underwent 24-h pH monitoring, oesophageal high-resolution manometry, and upper abdominal contrast-enhanced multidetector computed tomography (MDCT) during 2014-2021 were enrolled. Patients with a hiatus hernia (HH) on MDCT or who had a history of gastro-oesophageal surgery were excluded. Multiplanar reconstruction (MPR) of the MDCT image was used for the measurement of OHSA. Correlations of OHSA with acid exposure time (AET) and lower oesophageal sphincter (LOS) pressure of all patients were analysed. RESULTS Seventy-eight patients were included in the study. OHSA was much less in the AET <4% group than in the AET >6% group (1.61 ± 0.42 versus 2.09 ± 0.55 cm2, p<0.001). Correlation analysis reveals that OHSA correlated positively with AET (correlation coefficient = 0.47, p<0.001). Receiver operating characteristic (ROC) curve analysis reveals that OHSA can significantly distinguish patients in different groups divided by AET (area under the ROC curve [AUC] = 0.76, 95% confidence interval [CI]: 0.63-0.90). OHSA was not related to LOS pressure (correlation coefficient = -0.268, p=0.051). There was no difference in OHSA between the low LOS pressure group and the normal LOS pressure group (1.84 ± 0.61 versus 1.74 ± 0.50 cm2, p=0.52). CONCLUSIONS OHSA significantly correlated with AET but has no relationship with LOS pressure. It may be an independent risk factor of GERD.

Abstract
PURPOSE/OBJECTIVE(S) Tumor-infiltrating Treg cells (TITR) negatively regulates anti-tumor immune response and promotes tumor progression. Increased levels of TITR cells have been associated with poor prognosis in multiple cancer indications which led to the development of immunotherapies that target tumor Tregs. CCR8 antibody is one of the best-in-class therapies in clinical development for depleting TITR cells. It has demonstrated potent efficacy in tumors that are responsive to checkpoint inhibitors but failed in cold tumors that lack immune infiltration and activation. Radiotherapy (RT) has been shown to induce pro-inflammatory responses in tumors, but still failed to show consistent synergy with checkpoint inhibitors. Here we test the hypothesis that RT synergizes with Treg depletion to improve anti-tumor efficacy by reprogramming the immune-excluded tumor microenvironment. MATERIALS/METHODS The CCR8 + RT combination therapy was tested in syngeneic mouse tumor models: 4T1 breast, LL2 lung, and B16F10 melanoma, all of which present a cold tumor phenotype. Tumor-bearing mice (n = 10 per group) received a single dose of focal irradiation by SARRP, 4 doses of anti-CCR8 depleting antibody or a combination of the two. Tumor size was measured 3 times per week, survival was monitored until day 42, and tumor metastasis was evaluated at endpoint by necropsy. Mouse tumors, spleens, draining lymph nodes, and blood were collected 1 day after the last dose of CCR8 therapy and analyzed by multi-color flow cytometry and RNA-sequencing for pharmacodynamics and mechanism studies. RESULTS In the syngeneic mouse models, CCR8+RT combination therapy displayed significantly improved tumor growth inhibition, metastasis control, and prolonged survival compared with either treatment alone, without increase in toxicity. Flow cytometry showed reduced TITR population and increased infiltration and activation of CD8+ cytotoxic T cells in the tumors of CCR8 + RT treated mice. Increased activation of CD8+ T cells was also observed in the blood and draining lymph nodes in mice treated with the combination therapy. Moreover, transcriptomic analysis identified up-regulation of pathways associated with TNF-α and IFN-γ response in the combination-treated tumors, suggesting the creation of a pro-inflammatory tumor microenvironment. Interestingly, these changes were only induced by the combination therapy, but not either treatment alone. CONCLUSION Immunotherapies targeting Treg/TITR cells have so far failed to show promise in clinical trials. Our data suggest that TITR depletion is not sufficient to treat tumors with minimal immune infiltration. Our animal data demonstrate that combining RT with CCR8 therapy significantly inhibited tumor growth and prevented metastasis by enriching the tumor microenvironment with pro-inflammatory cytokines and activated cytotoxic T cells. These findings have clinical relevance to apply TITR depletion therapy in combination with RT.

Abstract
Objective: To understand the clinical and genetic characteristics of hereditary spherocytosis (HS) combined with cholestasis among pediatric patients. Methods: 12 cases of HS children accompanied by cholestasis at Hunan Children's Hospital were selected as the research subjects between January 2013 and December 2022. Clinical data were collected. Whole-exome sequencing was performed by second-generation sequencing. Suspected pathogenic mutation sites were verified by Sanger sequencing. Results: All pediatric patients were admitted to the hospital due to their yellow skin tone. Eight cases (66.67%) had a positive family history. The clinical manifestations were jaundice, splenomegaly (12/12), abdominal pain, anemia (4/12), and hepatomegaly (5/12). All pediatric patients had decreased hemoglobin, an increased reticulocyte ratio, total bilirubin and direct bilirubin, a positive erythrocyte fragility test, and remarkable spherical erythrocytes in their peripheral blood. Seven cases had elevated aminotransferase; four cases had severely elevated aminotransferase and bilirubin; eight cases had biliary calculi; and two cases had a dilated biliary tract. Liver pathological examination showed mild damage to the liver cells (G1S1) in three pediatric cases. Five children had a total of six unreported mutations: SPTB gene c.2431_2450del, c.4974-2A > G, c.2575G > A, and exon 22-35 deletion; ANK1 gene: c.2379-2380delC; and c .6dupC. Children still had abnormal bilirubin levels following treatment. Two pediatric cases underwent splenectomy. Bilirubin and hemoglobin levels returned to normal after surgery. Conclusion: Children with HS may experience cholestasis, and those with poor treatment results may consider undergoing a splenectomy. Six new types of variants have expanded the HS gene mutation spectrum.

Abstract
BACKGROUND Enolase 1 (ENO1) is a metabolic enzyme which participates in pyruvate synthesis and ATP production in cells. Previously, differential expression of ENO1 was discovered in villous tissues between recurrent miscarriage and induced abortion. This study was designed to explore whether ENO1 influences the proliferation and invasion of villous trophoblasts and the related molecular mechanisms. METHODS First, ENO1 expression in placental villus tissues collected from recurrent miscarriage (RM) patients and women for induced abortion as well as in trophoblast-derived cell lines was detected by RT-qPCR and western blotting. ENO1 localization and expression in villus tissues were further confirmed through immunohistochemistry staining. Then, the effects of ENO1 downregulation on trophoblast Bewo cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) process were evaluated by CCK-8 assay, transwell assay, and western blotting. As for the regulatory mechanism of ENO1, the expression of COX-2, c-Myc and cyclin D1 in Bewo cells after ENO1 knockdown was finally evaluated by RT-qPCR and western blotting. RESULTS ENO1 was mainly localized in the cytoplasm, with very small amounts in the nucleus of trophoblast cells. ENO1 expression in the villi tissues of RM patients was significantly increased, when compared with the villous tissues of healthy controls. Furthermore, Bewo cells, a trophoblast cell line with relatively higher expression of ENO1, was used to downregulate the ENO1 expression by ENO1-siRNA transfection. ENO1 knockdown significantly facilitated Bewo cell growth, EMT process, migration, and invasion. ENO1 silencing markedly elevated COX-2, c-Myc, and cyclin D1 expression. CONCLUSION ENO1 may participate in the development of RM via suppressing the growth and invasion of villous trophoblasts via reducing the expression of COX-2, c-Myc, and cyclin D1.

Abstract
Objective: To investigate the curative effects of bi-pedicled deep inferior epigastric perforator (DIEP) flap in repairing large soft tissue defects in the lower limbs. Methods: A retrospective observational study was conducted. From February 2016 to June 2020, 16 patients with large soft tissue defects in the lower limbs caused by trauma or after tumor/scar resection were admitted to the Department of Hand Surgery of the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, including 9 males and 7 females, aged 25-58 years, with the area of soft tissue defects ranging from 14.0 cm×8.0 cm to 32.0 cm×18.0 cm. Using the abdomen as the donor site, the conjoined abdominal wall flap, i.e., the bi-pedicled DIEP flap (with an area ranging from 15.0 cm×9.0 cm to 32.0 cm×20.0 cm) carrying two sets of the trunk of the deep inferior epigastric artery was designed and resected to repair the wound. The donor site wound was sutured directly. The flap survival and wound healing in the donor and recipient areas were observed after operation. The curative effect was evaluated during the follow-up. At the last follow-up, the American Knee Society score and lower extremity functional scale were used to assess the functions of knee joint and lower limb, respectively. Results: The flaps of 15 patients survived after operation; the flap of one patient had partial infection at the edge after operation but healed after debridement and dressing change. The wounds in the donor and recipient areas of 16 patients all healed well. Follow-up of 16-28 months showed that the recipient area had a good shape and pliable texture, and there was no obvious swollen appearance, hyperpigmentation, or abnormal hair growth; the donor site had linear scar only, with no complications such as abdominal hernia or hyperplastic scar; the functions of knee joint and lower limb were well reconstructed, with no recurrence of tumor. At the last follow-up, among the 4 patients with knee joint injury, 3 cases were excellent and 1 case was good in the evaluation of knee joint function; among the 12 patients with lower limb injury, 9 cases were excellent and 3 cases were good in the evaluation of lower limb function. Conclusions: The donor site of bi-pedicled DIEP flap is concealed with abundant tissue and large area for resection, with which can be used to repair large soft tissue defects in the lower limbs, achieving good short-term results of appearance and function restoration.

Abstract
OBJECTIVE To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. METHODS The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. RESULTS A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 104 km2 in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 104 km2 in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). CONCLUSIONS The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.

Abstract
Objective: To understand the vaccination status of enterovirus type 71 (EV71) inactivated vaccines in China from 2017 to 2021 and provide evidence for making policy on immunization strategy against hand, foot and mouth disease (HFMD). Methods: Using the reported dose number of EV71 vaccination and birth cohort population data collected by the China immunizaiton program information system to estimate the cumulative coverage of EV71 vaccine by the end of 2021 among the birth cohorts since 2012 at national, provincial, and prefecture levels, and analyze the correlation between the vaccination coverage and the potential influencing factors. Results: As of 2021, the estimated cumulative vaccination coverage of the EV71 vaccine was 24.96% in birth cohorts since 2012. The cumulative vaccination coverage was between 3.09% and 56.59% in different provinces, between 0 and 88.17% in different prefectures. There was a statistically significant correlation between vaccination coverage in different regions and the region's previous HFMD prevalence and disposable income per capita. Conclusions: Since 2017, the EV71 vaccines have been widely used nationwide, but the coverage of EV71 vaccination varies greatly among regions. Vaccination coverage is higher in relatively developed regions, and the intensity of previous epidemic of HFMD may have a certain impact on the acceptance of the vaccine and the pattern of immunization service. The impact of EV71 vaccination on the epidemic of HFMD requires further studies.

Abstract
Previous studies have shown that HE4 cancer biomarker promoted cancer cell proliferation and tumor growth in mouse xenograft models. Interestingly, HE4 levels are significantly increased in the seminal plasma of oligoasthenospermia patients, raising a question on HE4 role(s) in spermatogenesis. We constructed an HE4 overexpression mouse model (HE4-OE), and observed that HE4-OE male adult mice had small testes, low sperm counts, and elevated serum/testis testosterone levels. These mice exhibited disorganized seminiferous tubules and impaired spermatogenesis. HE4 overexpression concentrated in Leydig cells, and these cells had hyperplasia and increased testosterone biosynthesis. Mechanistic studies indicated that the impaired spermatogenesis was likely caused by a local and direct action of HE4 in the testis rather than by a hypothalamus/pituitary-initiated dysregulation. The new findings reveal a novel HE4 function in male reproductive system, and suggest the existence of a subtype of primary oligoasthenospermia characterized by HE4 overexpression, Leydig cell hyperplasia, and elevated testosterone levels.

Abstract
BACKGROUND AND PURPOSE Hemorrhagic transformation (HT) is the most serious complication of intravenous thrombolysis in ischemic stroke patients. Inflammation plays a critical role in the pathological progression of HT. This study was to explore the relationship between fibrinogen-to-albumin ratio (FAR), a novel systemic inflammation biomarker, and HT after intravenous thrombolysis in patients with ischemic stroke. METHODS This retrospective study enrolled ischemic stroke patients who underwent intravenous thrombolysis between Jan 2017 to May 2022. The characteristic data of all patients at admission were retrospectively collected. The univariate and multivariate logistic regression analyses were performed to evaluate the correlation between FAR and HT after intravenous thrombolysis. The optimal cut-off value of FAR for predicting HT was determined by the receiver operating characteristic curve. RESULTS A total of 363 ischemic stroke patients were enrolled in the present study. Sixty-two patients had HT after intravenous thrombolysis. In multivariate regression analysis, FAR was significantly associated with HT (odds ratio [OR], 1.105; 95% confidential interval [CI], 1.029-1.186, P = 0.006). The receiver operating characteristic curve analysis indicated FAR predicts HT after intravenous thrombolysis with an AUC of 0.613 (95%CI, 0.530-0.695; P = 0.005) and an optimal cut-off value of 0.101. The correlation between FAR and HT after intravenous thrombolysis was still observed when patients were stratified according to FAR levels. A higher FAR level was independently related to the occurrence of HT after adjusting for the potential confounding factors. CONCLUSION Higher FAR level was independently associated with HT after intravenous thrombolysis in patients with ischemic stroke.

Abstract
Understanding the relationship between ecosystem service value and ecological risk evolutions holds great theoretical and practical significance, as it helps to ensure the quality management of ecosystems and the sustainable development of human-land system interactions. We analyzed this relationship in the Dongting Lake area in China from 1995 to 2020 using data from remote sensing-interpreted land use with ArcGIS and Geoda. We used the equivalent factor method to estimate the ecosystem service value, constructed a landscape ecological risk index to quantitatively describe the ecological risk of Dongting Lake, and analyzed their correlation. The results show that: (1) over the last 25 years, the ecosystem service value decreased by 31.588 billion yuan, with higher values in the middle of the area and lower values in the surroundings-the highest value was found in forested land and the lowest was for unutilized land; (2) the ecological risk index also decreased slowly over time, from the perspective of single land use type, the ecological risk value of construction land was the lowest, followed by woodland, grassland, and cultivated land, with water area being the highest-the ecological risk level presents the distribution state of whole piece and local aggregation; and (3) the ecological risk index in Dongting Lake area demonstrated positive spatial correlation, and the spatial agglomeration of land with similar risk levels showed a decreasing trend. Areas with strong partial spatial correlations between ecosystem service value and ecological risk index are mainly distributed in the central water areas and their surrounding areas. This study investigates the rational utilization of land resources, and the sustainable development of regional ecological security in Dongting Lake area.

Abstract
BACKGROUND Ischemic stroke is a common cerebrovascular disease with high morbidity, disability, and mortality worldwide. Currently, recombinant tissue plasminogen activator is the main intravenous thrombolysis agent for the treatment of acute ischemic stroke within 4.5 h after onset. Hemorrhagic transformation (HT) is the most serious complication of intravenous thrombolysis, which can significantly aggravate clinical poor prognosis. Therefore, it is important to early predict the risk of post-thrombolysis HT in patients with acute ischemic stroke. SUMMARY Recently, several studies have reported that neuroimaging techniques have potential value in predicting HT after intravenous thrombolysis in patients with acute ischemic stroke. The corresponding neuroimaging parameters may be effective predictors of HT after intravenous thrombolysis. In this review, we summarized and discussed the application of neuroimaging techniques and related parameters in predicting HT after intravenous thrombolysis. KEY MESSAGES Recognizing and understanding the predictive performance of neuroimaging parameters for HT may help assess the risk of HT after intravenous thrombolysis in patients with acute ischemic stroke and make an appropriate treatment decision.

Abstract
Ferroptosis is a form of cell death caused by the accumulation of lipid peroxidation products due to abnormal iron metabolism. However, it remains unknown whether ferroptosis participates in the process of radiation-induced ovarian injury. Sphingosine-1-phosphate (S1P) is an important bioactive sphingolipid that has a protective effect on ovarian injury. The present study aims to determine whether X-ray radiation induces ferroptosis in the ovarian granulosa KGN cell line, and explore the potential effect of S1P and its mechanism in radiation-induced ferroptosis. The results indicated that irradiation reduced the viability of KGN cells, altered the mitochondrial morphology, induced the intracellular accumulation of iron ions, increased oxidative stress, and induced lipid peroxidation. Furthermore, the radiation exposure triggered the ferroptosis in KGN cells. S1P can alleviate radiation-induced ferroptosis. Furthermore, the protective effect of S1P was reversed after the application of siRNA to interfere with the glutathione peroxidase 4 expression. Ferroptosis might be pervasive in radiation-induced ovarian injury, and S1P may serve as a potential therapeutic approach to protect against the toxic effect of radiation in female gonads by inhibiting ferroptosis.

Abstract
Objective: To analyze the trust in vaccination and its influencing factors in parents of children aged 0-6 years. Methods: In June 2021, a cross-sectional survey was conducted to collect the basic information of parents of children aged 0-6 years, including their trust in vaccination and their attitudes towards vaccination. The χ2 test was used to compare the difference between different groups, and logistic regression was used to analyze the influencing factors. Results: A total of 10 916 parents of children aged 0-6 years were investigated in this study, and their trust in vaccine was 67.20%, of which safety (55.80%) was the key factor limiting the trust in vaccination. 37.94% (4 142/10 916) of the parents were willing to vaccinate more than two kinds of vaccines at the same time, and 85.07% (9 286/10 916) of the parents feared that abnormal reactions would occur after vaccination. The parents' age, education level and annual family income were the promoting factors of their trust in vaccination (P<0.05). Obtaining vaccine knowledge through vaccination APP or official account (OR=1.330, 95%CI: 1.188-1.489) and popular science leaflets distributed by vaccination clinics (OR=1.120, 95%CI: 1.020-1.228) were the promoting factors of parents' trust in vaccination. Young children and parents, high family income and education level were the promoting factors for parents to be willing to vaccinate at the same time (P<0.05), and young children and parents, low family income and education level were the inducing factors for fear of abnormal reaction after vaccination (P<0.05). Parents of children in the central region had a high acceptance of simultaneous vaccination for children, while parents of children in the western region had a low degree of concern about abnormal reactions after vaccination (P<0.05). Parents of children who read books and got vaccine knowledge online (OR=1.257, 95%CI: 1.153-1.371), urban residents (OR=1.173, 95%CI: 1.062-1.295) and with jobs (OR=1.109, 95%CI: 1.015-1.212) were more willing to vaccinate at the same time. The choice of imported vaccine was a promoting factor for parents to worry about abnormal reactions after vaccination (P<0.05). Conclusion: There is room for parents of children aged 0-6 years to further improve their trust in vaccination. At this stage, it is necessary to innovate the way of health education and health promotion, and pay attention to the publicity of vaccine safety knowledge, so as to improve parents' trust in vaccination.

Abstract
The prolongation of patient's overall survival is the accepted as gold standard to prove clinical values of anti-cancer drugs. However, if overall survival is taken as the primary endpoint in clinical trials for cancer types with a relatively good prognosis in the process of new anti-cancer drug research and development, the time to market the drugs will be prolonged due to the long follow-up time. In addition, overall survival is often interfered by confounding factors such as follow-up treatment. Therefore, regulatory agencies have established an accelerated review model using surrogate endpoints for the approval of new anti-cancer drugs, but there are still some problems in the use of surrogate endpoints in cancer clinical trials. From the perspective of new drug review, the authors expounds the key points of confirming and rationally using surrogate endpoints in clinical trials of anti-cancer drugs, which will improve the level of clinical trials of new anti-cancer drugs and accelerate the development of anti-tumor drugs.

Abstract
Objective: To evaluate the quality of life and influencing factors of patients with herpes zoster (HZ) seen in hospitals. Methods: Based on Zoster Brief Pain Inventory (ZBPI) and Five-level EuroQol Five-dimensional Questionnaire (EQ-5D-5L), a cross-sectional survey was conducted to evaluate the pain severity and quality of life of 332 HZ cases seen in 22 hospitals of Lu'an City (Anhui Province), Zibo City (Shandong Province) and Tongchuan City (Shaanxi Province) from October to December 2021. The censored least absolute deviations (CLAD) model was used to analyze the related factors affecting the changes of patients' health utility values. Results: The 45.5% of 332 HZ cases were male. The median (Q1,Q3) age was 59 (50, 68) years. 59.64% of them assessed by ZBPI had moderate to severe pain in the past 24 hours (worst pain score≥5), and that of PHN cases was 84.8%(39/46). 77.7% (258/332), 77.4% (257/332) and 74.1% (246/332) of all patients reported that pain interfered with sleep, mood and general activities, respectively. Aging [β40-49y (95%CI)=-0.11 (-0.15, -0.08); β50-59y (95%CI)=-0.03 (-0.05, 0.00); β60-69y (95%CI)=-0.09 (-0.12, -0.06); β70-90y(95%CI)=-0.16 (-0.19, -0.12)], working status (unemployed) [βfarmer (95%CI)=0.15 (0.13, 0.18); βretirees(95%CI)=0.21 (0.18, 0.24); βemployee (95%CI)=0.13 (0.10, 0.16) ], complications[βPHN (95%CI)=-0.08 (-0.13, -0.04); βother complications (95%CI)=-0.12 (-0.15, -0.08)], within 30 days after onset [β(95%CI)=-0.01 (-0.03, 0.01)] and treatment [βother complications (95%CI)=-0.09 (-0.11, -0.06)] were related factors for the decline of health utility value (all P values <0.05). Conclusions: More than half of the patients with HZ had moderate to severe pain in the past 24 hours, which had a serious negative impact on the physical and mental health of the patients. Elderly patients, acute patients and patients with complications had lower health utility values and worse health status. We suggest that eligible people be vaccinated with HZ vaccine as soon as possible.

Abstract
OBJECTIVE To investigate the relationship between ovulation and pregnancy outcomes in patients undergoing intrauterine insemination (IUI). METHODS The clinical data from 784 patients, diagnosed with polycystic ovarian syndrome (PCOS) or unexplained infertility, underwent 1624 IUI cycles were analyzed retrospectively. Ovulation was observed by transvaginal ultrasonography on the day of IUI. The clinical pregnancy rate (CPR), abortion rate (AR), and live birth rate (LBR) were analyzed. RESULTS The study included 1031 pre-ovulation IUI cycles (63.49%) and 593 post-ovulation IUI cycles (36.51%). The CPR was 13.05%, the AR was 15.57%, and the LBR was 11.02%. Ovulation before or after IUI affected the CPR (11.06% VS 16.53%, p = .002) and LBR (9.41% VS 13.83%, p = .006) per cycle, but did not affect the AR (14.91% VS 16.33%, p = .149). The sex ratio of children was not related to ovulation (p = .948). After adjusting for baseline characteristics and logistic regression, the CPR (OR = 1.931, 95% CI 1.062-1.931, p = .019) and LBR (OR = 1.389, 95% CI 1.007-1.916, p = .045) of post-ovulation insemination were higher than those of pre-ovulation insemination significantly. CONCLUSION Pregnancy outcomes were affected by ovulation on the day of IUI in patients with unexplained infertility or PCOS. Post-ovulation insemination may improve the CPR of IUI.

Abstract
On May 14, 2020, a 37 year old female patient with unilateral breast cancer was admitted to Hunan Cancer Hospital. She underwent modified radical mastectomy for right breast cancer and free transplantation of bilateral superficial inferior epigastric artery perforator flap (weighed 305 g) for breast reconstruction. During the operation, the right inferior epigastric vascular pedicle was anastomosed with the proximal end of the right internal mammary vessel, and the left inferior epigastric vascular pedicle was anastomosed with the distal end of the right internal mammary vessel; the blood flow of the flap was good; the wound in the donor site of the abdominal flap was closed directly. The operation lasted for 9 hours. In the first 48 hours post operation, the flap showed mild elevation in perfusion over drainage, but no obvious edema or blister was observed, flap temperature was consistent with the surrounding skin, and the drainage volume out of drainage tube was only 40 mL. The blood supply of the flap was completely restored to normal 3 days post operation, the flap survived well, the donor site incision had no obvious tension, and the healing was smooth. After 2 months of follow-up, the donor site incision of abdomen healed completely, only linear scar was left, and the reconstructed breast had a natural appearance; the patient planned to perform further nipple reconstruction and contralateral breast mastopexy. This case suggests that autologous breast reconstruction can be performed using bilateral superficial inferior epigastric artery perforator flaps under certain circumstances to minimize donor site injury to the greatest extent.

Abstract
BACKGROUND The management of physical symptoms and psychological distress of cancer patients is an important component of cancer care. The purpose of this study was to evaluate the symptom burden, psychological distress, and management status of hospitalized patients with advanced cancer in China and explore the potential influencing factors of undertreatment and non-treatment of symptoms. PATIENTS AND METHODS A total of 2930 hospitalized patients with advanced cancer (top six types of cancer in China) were recruited from 10 centers all over China. Patient-reported MD Anderson Symptom Inventory, Hospital Anxiety and Depression Scale (HADS), and Patient Health Questionnaire-9 (PHQ-9) scales and symptom management-related information were collected and linked with the patient's clinical data. The proportion of patients reporting moderate-to-severe (MS) symptoms and whether they were currently well managed were examined. Multivariable logistic regression models were applied to explore the factors correlated to undertreatment and non-treatment of symptoms. RESULTS About 27% of patients reported over three MS symptoms, 16% reported over five, and 9% reported over seven. Regarding psychological distress, the prevalence of HADS-anxiety was 29% and that of PHQ-9 depression was 11%. Sixty-one percent of patients have at least one MS symptom without any treatment. Sex [odds ratio (OR) = 2.238, 95% confidence interval (95% CI) 1.502-3.336], Eastern Cooperative Oncology Group (ECOG; OR = 0.404, 95% CI 0.241-0.676), and whether currently undergoing anticancer treatment (OR = 0.667, 95% CI 0.503-0.886) are the main factors correlated with the undertreatment of symptoms. Age (OR = 1.972, 95% CI 1.263-3.336), sex (OR = 0.626, 95% CI 0.414-0.948), ECOG (OR = 0.266, 95% CI 0.175-0.403), whether currently undergoing anticancer treatment (OR = 0.356, 95% CI 0.249-0.509), and comorbidity (OR = 0.713, 95% CI 0.526-0.966) are the main factors correlated with the non-treatment of symptoms. CONCLUSIONS This study shows that hospitalized patients with advanced cancer had a variety of physical and psychological symptoms but lacked adequate management and suggests that a complete symptom screening and management system is needed to deal with this complex problem.

Abstract
Objective: To explore the safety and feasibility of stereotactic radiation therapy (SBRT) strategy for irradiating porcine ventricular septum, see if can provide a preliminary experimental evidence for clinical SBRT in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: Five male pigs (39-49 kg, 6 months old) were used in this study. Pigs were irradiated at doses of 25 Gy (n=2) or 40 Gy (n=3). Delineation of the target volume was achieved under the guidance of 3-dimensional CT image reconstruction, and SBRT was then performed on defined target volume of porcine ventricular septum. Blood biomarkers, electrocardiogram and echocardiography parameters were monitored before and after SBRT. Pathological examination (HE staining, Masson staining) was performed on the target and non-target myocardium at 6 months post SBRT. Results: SBRT was successful and all animals survived to the designed study endpoint (6 months) after SBRT. Serum cardiac troponin T (cTnT) level was significantly higher than the baseline level at 1 day post SBRT, and reduced at 1 week after SBRT, but was still higher than the baseline level(P<0.05). Serum N-terminal pro-B type natriuretic peptide (NT-proBNP) was also significantly increased at 1 day post SBRT (P<0.05) and returned to baseline level at 1 week post SBRT. The serum NT-proBNP level was (249±78), (594±37) and (234±46) pg/ml, respectively, and the cTnT was (14±7), (240±40) and (46±34) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 40 Gy dose group. The serum NT-proBNP level was (184±20), (451±49) and (209±36) pg/ml, respectively, the cTnT values were (9±1), (176±29) and (89±27) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 25 Gy dose group. Both NT-proBNP and cTnT values tended to be higher post SBRT in the 40 Gy dose group as compared with the 25 Gy dose group, but the difference was not statistically significant (P>0.05). The left ventricular ejection fraction and the left ventricular end-diastolic diameter remained unchanged before and after SBRT (P>0.05). The interventricular septum thickness showed a decreasing trend at 6 months after SBRT, but the difference was not statistically significant ((9.54±0.24) mm vs. (9.82±8.00) mm, P>0.05). The flow velocity of the left ventricular outflow tract, and the valve function and morphology were not affected by SBRT. At 6 months after SBRT, HE staining revealed necrosis in the irradiated target area of the myocardium in the 40 Gy dose group and the 25 Gy dose group, and the degree of necrosis in the irradiated interventricular septum was more obvious in the 40 Gy dose group as compared with the 25 Gy group. The combined histological analysis of the two groups showed that the necrotic area of the irradiated target area accounted for (26±9)% of the entire interventricular septum area, which was higher than that of the non-irradiated area (0) (P<0.05). There was no damage or necrosis of myocardial tissue outside the target irradiation area in both groups. The results of Masson staining showed that the percentage area of myocardial fibrosis was significantly higher in the irradiated target area than non-irradiated area ((12.6±5.3)% vs. (2.5±0.8)%, P<0.05). Conclusion: SBRT is safe and feasible for irradiating porcine ventricular septum.

Abstract
Quantitative testing of BK virus (BKPyV) nucleic acid has become the standard of care in transplant patients. While the relationship between interassay harmonization and commutability has been well characterized for other transplant-related viruses, it has been less well studied for BKPyV, particularly regarding differences in commutability between matrices. Here, interassay agreement was evaluated among six real-time nucleic acid amplification tests (NAATs) and one digital PCR (dPCR) BKPyV assay. Differences in the commutability of three quantitative standards was examined across all assays using a variety of statistical approaches. Panels, including 40 samples each of plasma and urine samples previously positive for BKPyV, together with one previously negative plasma sample and four previously negative urine samples, were tested using all assays, with each real-time NAAT utilizing its usual quantitative calibrators. Serial dilutions of WHO, National Institute for Standards and Technology (NIST), and commercially produced (Exact/Bio-Rad) reference materials were also run by each assay as unknowns. The agreement of the clinical sample values was assessed as a group and in a pairwise manner. The commutability was estimated using both relativistic and quantitative means. The quantitative agreement across assays in the urine samples was within a single log10 unit across all assays, while the results from the plasma samples varied by 2 to 3 log10 IU/mL. The commutability showed a similar disparity between the matrices. Recalibration using international standards diminished the resulting discrepancies in some but not all cases. Differences in the sample matrix can affect the commutability and interassay agreement of quantitative BKPyV assays. Differences in commutability between matrices may largely be due to factors other than those such as amplicon size, previously described as important in the case of cytomegalovirus. Continued efforts to standardize viral load measurements must address multiple sources of variability and account for differences in assay systems, quantitative standards, and sample matrices.

Abstract
INTRODUCTION Linezolid is a synthetic oxazolidinone antimicrobial drug with a broad spectrum and a unique mechanism of inhibiting resistant pathogenic strains, and it was approved by the Food and Drug Administration (FDA) in April 2000. Several different systemic side effects were reported after the use of this medication. In this article, we report a case in which a syndrome of inappropriate antidiuretic hormone (SIADH) was developed after linezolid treatment was started. CASE PRESENTATION We present the case of a 79-year-old woman who developed severe hyponatremia during linezolid treatment (0.6 g i.v. q12 h) after undergoing hemiarthroplasty for left femoral neck fracture. The patient's baseline serum sodium upon admission (138 mmol/L) decreased to 118 mmol/L, urine sodium was 102 mmol/L, plasma osmolality was 248 mOsm/kg and urine osmolarity was 310 mOsm/kg at day 4, thus a diagnosis of SIADH was made. The patient was not taking any other medication known to cause SIADH, and she did not present a comorbidity that could explain her condition. Her serum sodium increased to 135 and 137 mmol/L, respectively, 11 and 12 days after cessation of linezolid, strongly suggesting that SIADH was the cause in this case. CONCLUSIONS This is the fourth case of linezolid-induced SIADH. A thorough workup was essential for the diagnosis to correctly differentiate between SIADH and other causes of hyponatremia, which helped us properly conducting follow-up treatments. SIADH is a rare but serious side effect of linezolid, and practicing physicians should be aware of this complication. It is necessary to periodically monitor the serum sodium.

Abstract
Abstract
Study question
Are paternal serum free thyroxine (FT4) concentrations within the reference range associated with outcomes of assisted reproductive technologies (ART)?
Summary answer
Men of older reproductive age (≥ 35 years old) with low FT4 concentrations within the reference range are associated with a decreased live birth rate.
What is known already
The impact of maternal thyroid dysfunction on ART outcomes has been widely elucidated. However, few studies have investigated the impact of paternal thyroid dysfunction on ART outcomes. Our previous study showed a detrimental impact of paternal subclinical hypothyroidism (SCH) on the clinical outcomes of ART. Patients with SCH had relatively lower concentrations of FT4 compared to those with euthyroidism. Therefore, it remains to be determined whether the detrimental impacts of paternal SCH on ART outcomes arise from low concentrations of FT4.
Study design, size, duration
This retrospective cohort study included 4,066 couples who received 4,894 ART treatment cycles in our clinic between 1 April 2016 and 31 August 2021.
Participants/materials, setting, methods
The differences in sperm parameters and ART outcomes across the paternal FT4 tertiles were compared using generalised linear models or generalised estimation equation models. The primary outcomes were the clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were sperm parameters, fertilisation rate, good-quality embryo rate, blastocyst formation rate, and implantation rate.
Main results and the role of chance
The mean ages of the males and their female partners were 33.0 and 31.0 years, respectively. No significant differences are observed in the sperm parameters and ART outcomes across the paternal FT4 tertiles in the overall population. However, stratified analysis of men aged ≥ 35 shows a non-significantly lower CPR in the lower paternal FT4 tertile (adjusted rate: 0.36, 95% CI: 0.27–0.45) relative to the middle (adjusted rate: 0.45, 95% CI: 0.38–0.53) and upper (adjusted rate: 0.43, 95% CI: 0.36–0.51) tertiles. The adjusted LBR is 0.21 (95% CI: 0.15–0.30) for men aged ≥ 35 in the lower FT4 tertile (p = 0.024, with reference to the upper tertile), 0.27 (95% CI: 0.21–0.35) for those in the middle tertile and 0.30 (95% CI: 0.23–0.38) for those in the upper tertile. No differences in these outcomes are seen among men aged < 35. The nonlinear smoothing curve obtained by using FT4 as a continuous variable further supports these findings.
Limitations, reasons for caution
Due to the retrospective design of the study, a causal relationship between paternal FT4 concentrations and ART outcomes could not be established. In addition, the study participants were patients who sought fertility treatment, which may have biased the results when we analysed the associations between FT4 concentrations and sperm parameters.
Wider implications of the findings
These results suggest that in older men, low paternal FT4 concentrations, although within the reference range, are associated with worse ART outcomes, especially LBR. Future prospective studies are warranted to confirm the detrimental effects of low paternal FT4 concentrations on ART outcomes.

Abstract
Single-arm trial refers to a clinical trial design that does not set up parallel control group, adopts open design, and does not involve randomization and blind method. These features, on the one hand, speed up the process of clinical trials, significantly shorten the time to market and meet the needs of patients with advanced malignancies, but also lead to the uncertainty of single-arm clinical trials themselves. Recently, the US Food and Drug Administration held a meeting of the oncologic drug advisory committee to discuss six tumor indications that have been accelerated approved, which once again triggered the discussion of single-arm trials. The basis of accelerated approval by single-arm trial is actually a compromise on the level of evidence-based medical evidence requirements after assessing the benefit risk. Therefore, the sponsor should strictly grasp the applicable conditions of single-arm trial in anti-tumor drugs and conduct single-arm trial scientifically. Post-marketing clinical trial should be implement as early as possible to ensure the benefit of patients. Based on the characteristics of single-arm trial, combined with two guidance relevant to single-arm trial issued by National Medical Products Administration recently, this article is supposed to propose and summarize the strategy of single-arm trial supporting the marketing of anti-tumor drugs.

Abstract
AIM To develop and validate a radiomics nomogram for prediction of degree of differentiation in lung adenocarcinoma presenting as sub-solid or solid nodules. MATERIALS AND METHODS A total of 438 patients with histopathologically confirmed adenocarcinoma (248 non-poorly differentiated and 190 poorly differentiated) were divided into training cohort (n=235) and internal validation cohort (n=203) according to surgery sequence. Sixty patients form public TCIA dataset were selected for external validation. One thousand, two hundred and eighteen radiomics features were extracted from each volumetric region of interest and a least absolute shrinkage and selection operator logistic regression was applied to select meaningful radiomic features for building a radiomics score (Rad-score) model. A nomogram model incorporating the Rad-score and type was established after multivariable logistic regression. The discrimination efficiency, calibration efficacy, and clinical utility value of the nomogram were evaluated. RESULTS The Rad-score model could predict the differentiation degree of lung adenocarcinoma with an area under the curve (AUC) of 0.83 (95% confidence interval [CI]: 0.78-0.89) in the internal validation cohort. The AUC of the nomogram and radiographic model was 0.86 (95% CI: 0.80-0.91), 0.78 (95% CI: 0.72-0.84) in the internal validation cohort respectively. The AUC of the nomogram in the external validation cohort was 0.73 (95% CI: 0.58-0.88). Delong's test showed that the nomogram performed better than radiographic features alone (p=0.001). CONCLUSIONS The proposed radiomics nomogram has the potential to predict the differentiation degree of lung adenocarcinoma preoperatively.

Abstract
BackgroundOligoarticular psoriatic arthritis (PsA) is commonly reported in early disease. Although fewer joints are involved, there may be significant impact on patients’ (pts) quality of life. The ongoing FOREMOST study (NCT03747939) is investigating the efficacy of apremilast vs placebo for treatment of early oligoarticular PsA (>1 but ≤4 tender and swollen joints involved).ObjectivesTo characterize disease burden in pts with early oligoarticular PsA and disease phenotype including location and size of involved joints and presence of certain baseline clinical PsA manifestations in FOREMOST pts.MethodsBaseline swollen and tender joint distribution was analyzed. Baseline disease burden was assessed in the overall group and a subgroup with small joint involvement only (for context) using clinical disease activity measures, pt-reported outcomes, and additional PsA manifestations.ResultsAt data cut-off for analysis, 220 pts of 285 planned were enrolled. In the overall group, disease duration was <1 year and joint distribution for swollen or tender joints involved predominantly small joints, with ~48% of joint involvement observed in finger proximal interphalangeal (PIP) joints and <2% in temporomandibular and clavicular joints across swollen or tender joints (Figure 1). Mean Physician’s and Patient Global Assessment of Disease Activity (PhGA and PtGA, respectively) scores were 43.9 and 51.3; mean pt pain assessment score was 50.7. Mean Health Assessment Questionnaire Disability Index (HAQ-DI) functional assessment score was 1.0; 25.5% of pts had HAQ-DI ≤0.5. Pts reported an average PsA Impact of Disease (PsAID-12) domain score of 4.7. Additional manifestations of PsA at baseline included dactylitis (14.5%), enthesitis (32.7%), nail involvement (67.3%), and skin disease (47.7% with body surface area [BSA] ≥3%). Within the overall group, 59% had >1 joint size involved (small [metacarpophalangeal, metatarsophalangeal, distal interphalangeal, PIP, hand carpometacarpal and mid-tarsal]; intermediate [wrist, elbow, ankle, temporomandibular, acromioclavicular, sternoclavicular]; large [shoulder, hip, knee]). Of those with only 1 joint size involved (41% of pts), the majority had small joint involvement predominantly in PIPs (n=84 for small joints; n=1 for intermediate joints; n=5 for large joints). The overall pattern of clinical and disease presentation indicated elevated burden for pts with early oligoarticular PsA, including those pts with only small joints involved (Table 1).Table 1.CharacteristicsOverall Population (PBO + APR), N=220Small Joints Only (PBO + APR), N=84Age, mean, y49.651.3Men, n (%)98 (44.5)40 (47.6)Europe/Russia, n (%)47 (21.4)/66 (30.0)22 (26.2)/11 (13.1)Canada/United States, n (%)8 (3.6)/99 (45.0)1 (1.2)/50 (59.5)Body mass index, mean, kg/m230.429.3Duration of disease, mean, y0.690.71Previous cDMARD use, n (%)143 (65.0)48 (57.0)Tender joint count (0–68), mean3.23.1Swollen joint count (0–66), mean2.62.8PhGA (VAS 0–100)a, mean43.939.0PtGA (VAS 0–100)a, mean51.345.6Patient’s Assessment of Pain (VAS 0–100)a, mean50.746.3Dactylitis present, n (%)32 (14.5)14 (16.7)Enthesitis present, n (%)72 (32.7)21 (25.0)BSA ≥3%, n (%)105 (47.7)34 (40.5)Nail involvement present, n (%)148 (67.3)53 (63.1)HAQ-DI (0–3)a, mean1.020.84HAQ-DI ≤0.5, n (%)56 (25.5)31 (36.9)PsAID-12 (0–10)a, mean4.733.98cDMARD, conventional disease-modifying antirheumatic drugs; VAS, visual analog scale.aHigher scores indicate greater burden/worse status.

Abstract
Objective: To analyze the clinical characteristics of Wilson's disease (WD) with onset of acute liver failure (ALF) in children. Methods: Clinical data of 19 children diagnosed with WD presented with ALF in Xi'an Children's Hospital from January 2016 to April 2021 were retrospectively analyzed, including general condition, clinical manifestation, laboratory examination, and gene detection. The children were divided into the death group and survival group according to the clinical outcome. The children who had hepatic WD with non-ALF onset during the same period were selected as the control. The general conditions and laboratory indexes were compared between death group and survival group, ALF group and non-ALF group. T-test, Mann Whitney U test or χ2 test were used to compare the differences between the two groups. Results: Of the 19 WD children with ALF onset, 10 were females and 9 were males. The age of admission was (10.1±2.6) years and time to onset of first visit was 9 (4, 15) days. Among the WD children with ALF onset, 4 children were lost to follow-up, 5 cases death (death group) and 10 cases survived (survival group). The ceruloplasmin in the death group was higher than that in the survival group (0.078 (0.055, 0.105) vs. 0.033 (0.027, 0.058) g/L, Z=-2.33, P=0.020). There were 95 children who had hepatic WD with non-ALF onset. The WD patients with ALF onset were older at admission (9.9 (8.0, 11.1) vs. 5.4 (3.7, 6.9) years, Z=-5.25, P<0.001), had higher ceruloplasmin (0.060 (0.030, 0.078) vs. 0.024 (0.006, 0.060) g/L, Z=-3.11, P=0.002), 24 h urinary copper (674 (205, 1 803) vs. 149 (108, 206) μg, Z=-4.25, P<0.001), and positive rate of K-F ring [17/19 vs. 7%(7/95), χ2=50.17, P<0.001] while shorter onset time at initial visit (0.3 (0.1, 0.5) vs. 1.0 (0.7, 6.0) months, Z=-4.28, P<0.001). There was no gender difference between the two groups [9/19 vs. 61%(58/95), χ2=1.22, P=0.269]. Of the 19 WD children with ALF onset, 13 had the ATP7B gene tested, and 15 reported variants were detected. The main variations were c.2333G>T (p. Arg778Leu), c.2621C>T (p. Ala874Val) and c.2975C>T (p. Pro992Leu). The allele frequencies were 6/26(23%), 4/26(15%) and 3/26(12%), respectively. Conclusions: Children of WD onset with ALF are school-aged and above. They have an acute onset, a short course of the disease, and poor prognosis. The positive rate of K-F ring, ceruloplasmin and urinary copper are higher than those of the hepatic WD children with non-ALF onset.
