Abstract
Background Sex differences in the outcomes of patients with aneurysmal subarachnoid hemorrhage (aSAH) remain controversial. The aim of this study was to evaluate sex differences in the outcomes of patients with aSAH. Method This study retrospectively analyzed the clinical data of consecutive patients with aSAH, admitted to the Department of Neurosurgery, Wuhan University Zhongnan Hospital, from May 1, 2020 to December 31, 2020. The modified Rankin Scale (mRS) score was used to evaluate the prognosis of patients at discharge. Outcome indicators included cerebral ischemia, hydrocephalus, and mRS ≥ 2 at discharge. Results The majority (65%) of the 287 patients with aSAH included in the study were females. Patients were divided into female (n = 184) and male (n = 99) groups; the female patients were significantly older than the male patients (61.3 ± 8.5 years vs. 60.0 ± 8.5 years, p = 0.032). The incidence of comorbidities (hypertension, diabetes, and heart disease) was higher in the female group than in the male group, but the difference was not statistically significant. Although more female patients than male patients underwent endovascular treatment, there was no statistical difference in the treatment approach between the two groups. Comparison of post-operative complications and mRS scores at discharge revealed that the rate of cerebral ischemia and mRS ≥ 2 at discharge were significantly higher among female patients than among male patients. Moreover, this difference persisted after propensity adjustment for age and treatment approach. Analysis of risk factors for poor prognosis at discharge in both pre- and post-adjustment patients revealed cerebral ischemia and high mFisher score (mFisher = 3/4) to be independent risk factors. Conclusion Female patients with aSAH have a worse prognosis than male patients, and this difference may be because women are more susceptible to cerebral ischemia.

Abstract
BACKGROUND Paraquat (PQ) poisoning induces severe acute kidney injury and causes extremely high rate of death. In this study, we aimed to investigate the protective effects of silymarin on PQ-induced acute kidney injury and explore the underlying mechanisms. METHODS A rat model was established through intraperitoneal injection of PQ. Rats were administrated with saline or silymarin for 3 days. Then, survival rate, physiological parameters, and renal injury score were evaluated. The apoptosis and oxidative stress in kidney tissues were determined through hematoxylin and eosin staining, quantitative reverse transcription polymerase chain reaction, Western blot, and enzyme-linked immunosorbent assays. RESULTS Silymarin administration could significantly increase the survival rate of PQ-poisoned rats. It was found that silymarin treatment improved renal function, decreased injury score in kidney tissues, and inhibited the apoptosis and oxidative stress in PQ-induced acute kidney injury through the activating the signaling pathway of Nrf2 and promoting its nuclear translocation. CONCLUSION Silymarin exhibited a protective effect against PQ-induced kidney injury, suggesting that treatment with this flavonoid could be a potential therapeutic agent for the treatment of acute kidney injury.

Abstract
BackgroundImproving the performance of bipolar coagulation forceps is crucial for safer and more accurate neurosurgery. In our department, we found that bone wax (BW) melted by thermal effect of bipolar electrocoagulation can achieve more efficient hemostasis and reduce the amount of BW in neurosurgical procedures associated with bleeding from emissary and diploic veins. Nevertheless, relevant studies are still lacking to verify our finding.ObjectiveThe study objectives were to evaluate the performance and safety in electrocoagulation: (1) compare the performance of BW coated bipolar coagulation forceps and the conventional anti-stick forceps in vivo, and (2) assess the safety of electrocoagulation with BW coated bipolar coagulation forceps in rat primary motor cortex.MethodsTissue adhesion was evaluated by comparing the wetting tension and the amount of protein adhered to the forceps tips after electrocoagulation. Thermal damage was assessed by analyzing the thermography and H&E staining of coagulated rat brain tissues. The hemostatic efficiency was reflected by the number of electrocoagulation until complete hemostasis and the condition of damaged common carotid arteries. The safety of BW coated forceps in electrocoagulation was assessed by evaluating the inflammation of coagulated rat primary motor cortex and the motor functions at the 7th day postoperatively.ResultsBone wax coated forceps had a significantly higher contact angle and adhered less coagulum. Thermography was acquired at 3 s, 6 W units in rat primary motor cortex in vivo. The highest temperature recorded during BW coated tips application was significantly lower than the uncoated. In addition, there was a relatively smaller tissue injury area produced by the BW coated forceps. Additionally, BW coated forceps improved the hemostatic efficiency and caused fewer injuries on the damaged arteries (3 s, 10 W units). More importantly, electrocoagulation with BW coated forceps led to no significant motor function impairments and less glial and microglia responses.ConclusionThis study reveals that BW coated bipolar coagulation forceps can provide a convenient, cost-efficient, safer, and more efficient way for hemostasis. More research is needed to evaluate the electrocoagulation with BW in the long term and verify our finding in human beings.

Abstract
Background: Previous studies had revealed that immune reconstitution (IR) after allogeneic hematopoietic stem-cell transplantation (allo-HSCT) affected the clinical prognosis of patients. However, few studies were based on pediatric patients and patients with aplastic anemia (AA). The purpose of this research was to analyze IR of pediatric AA after HSCT and further explore its clinical prognostic value. Methods: The whole of 61 pediatric patients with AA who underwent HSCT were enrolled. Lymphocyte subsets count in peripheral blood, CD4+/CD8+ T cell ratio, and serum concentration of immunoglobulins were detected using flow cytometry at regular intervals after HSCT. Results: Innate immunity recovered faster than adaptive immunity, T lymphocytes recovered faster than B lymphocytes. The number of transfused CD34+ cells and the implantation time of ANC significantly affected the early rapid IR of CD3+ T cells. The degree of HLA site coincidence significantly affected the early rapid IR of CD19+ B cells. The number of transfused MNC and CD34+ cells significantly affected the early rapid IR of CD56+ NK cells. The overall survival (OS) and failure-free survival (FFS) of CD56+ NK cells in early rapid IR group were higher than those in non-IR group. The CD3+ T cell early rapid IR group and CD8+ T cell early rapid IR group had higher OS than the non-IR group. Conclusion: Early rapid IR after HSCT is a good predictor of clinical prognosis in children with AA. This study provides a reasonable prediction for early rapid IR, which may improve clinical outcomes of children.

Abstract
Background Protein disulfide isomerase A3 (PDIA3, also named GRP58, ER-60, ERp57) is conserved across species and mediates protein folding in the endoplasmic reticulum. PDIA3 is, reportedly, a chaperone for STAT3. However, the role of PDIA3 in regulating mitochondrial bioenergetics and STAT3 phosphorylation at serine 727 (S727) has not been described. Methods Mitochondrial respiration was compared in immortalized human cerebral microvascular cells (CMEC) wild type or null for PDIA3 and in whole organism C. Elegans WT or null for pdi-3 (worm homologue). Mitochondrial morphology and cell signaling pathways in PDIA3-/- and WT cells were assessed. PDIA3-/- cells were subjected to oxygen–glucose deprivation (OGD) to determine the effects of PDIA3 on cell survival after injury. Results We show that PDIA3 gene deletion using CRISPR-Cas9 in cultured CMECs leads to an increase in mitochondrial bioenergetic function. In C. elegans, gene deletion or RNAi knockdown of pdi-3 also increased respiratory rates, confirming a conserved role for this gene in regulating mitochondrial bioenergetics. The PDIA3-/- bioenergetic phenotype was reversed by overexpression of WT PDIA3 in cultured PDIA3-/- CMECs. PDIA3-/- and siRNA knockdown caused an increase in phosphorylation of the S727 residue of STAT3, which is known to promote mitochondrial bioenergetic function. Increased respiration in PDIA3-/- CMECs was reversed by a STAT3 inhibitor. In PDIA3-/- CMECs, mitochondrial membrane potential and reactive oxygen species production, but not mitochondrial mass, was increased, suggesting an increased mitochondrial bioenergetic capacity. Finally, PDIA3-/- CMECs were more resistant to oxygen–glucose deprivation, while STAT3 inhibition reduced the protective effect. Conclusions We have discovered a novel role for PDIA3 in suppressing mitochondrial bioenergetic function by inhibiting STAT3 S727 phosphorylation.

Abstract
Gamma-glutamylcyclotransferase (GGCT) can promote the progression of osteosarcoma (OS). MicroRNAs also play significant roles in regulating the progression of OS. This study was designed to investigate whether miR-877 exerts its function in OS by targeting GGCT. The proliferation of OS cells (Saos-2 and U2OS) was detected by MTT and colony formation assays. The migration and invasion of OS cells were detected by transwell assays. The expressions of miRNAs and GGCT were detected by quantitative real-time PCR and Western blot. The luciferase reporter assay was performed to assess whether miR-877 could target GGCT. miR-877 was down-regulated both in OS tissues and OS cell lines (Saos-2 and U2OS). The overexpression of miR-877 inhibited the proliferation, migration, and invasion of OS cell lines, while the knockdown of miR-877 could negate effects. The expression of GGCT was increased in Saos-2 and U2OS cells. miR-877 could target GGCT, and the mRNA level of GGCT in Saos-2 and U2OS cells was decreased by the overexpression of miR-877. miR-877 overexpression inhibited the migration and invasion and suppressed the proliferation of Saos-2 and U2OS cells, and the overexpression of GGCT reversed this effects. The knockdown of miR-877 promoted the migration and invasion and facilitated the proliferation of Saos-2 and U2OS cells, and the silence of GGCT abolished this effects. Our findings suggested that miR-877 could inhibit the proliferation, migration, and invasion of OS cells by targeting GGCT.

Abstract
BACKGROUND There have been few reports on the use of tirofiban in ruptured intracranial aneurysms and the results were conflicting. However, the safety and efficacy of optimal dosage and the reasonable treatment course of tirofiban have not been determined. OBJECTIVE To determine the safety and efficacy of a new protocol for its prophylactic tirofiban application during the endovascular treatment of ruptured intracranial aneurysms with no oral antiplatelet medications. METHODS This retrospective study was based on 105 patients with ruptured aneurysms who underwent stent-assisted coiling at our institution between August 2017 and July 2020. Intravenous tirofiban was administered to patients after stent deployment. Tirofiban was administered as an intravenous bolus (5 µg/kg) over a 3 min period immediately after stent deployment, followed by a 0.06-0.08 µg/kg/min maintenance infusion for 12-24 h. Dual oral antiplatelet therapy was overlapped with half the tirofiban dose 2 h before the cessation of the tirofiban infusion. Cases of intracranial hemorrhage or thromboembolism were recorded. RESULTS This study included a total of 105 patients with ruptured intracranial aneurysms, who underwent stent-assisted coiling. In terms of clinical severity, a presenting Hunt-Hess clinical-grade I was observed in 47 (44.8%) cases, grade II in 19 (18.1%) cases, grade III in 30 (28.6%) cases, grade IV in 6 (5.6%) cases, and grade V in 3 (2.9%) cases. None of the patients showed a newly developed tirofiban-related intracerebral hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, or ventriculostomy-related hemorrhage. There were 3 (2.8%) patients who had thromboembolic complications. CONCLUSIONS We have determined a new protocol for prophylactic intraoperative tirofiban during the endovascular treatment of ruptured intracranial aneurysms with no oral antiplatelet medications. In our study, tirofiban showed a low risk of hemorrhagic or thromboembolic complications. Tirofiban appears to be a safe and alternative during the stent-assisted coiling of ruptured intracranial aneurysms.

Abstract
OBJECTIVE To evaluate the clinical efficacy of haploidentical haematopoietic stem cell transplantation (haplo-HSCT) for the treatment of malignant infantile osteopetrosis (MIOP) and intermediate osteopetrosis. METHODS Children with MIOP and IOP who underwent haplo-HSCT in Beijing Children's Hospital, Capital Medical University, from January 2010 to May 2018 were retrospectively analysed. Data relating to the clinical manifestations, engraftment, and prognosis of the children were extracted from medical records. RESULTS Twenty-seven patients, including 18 males and 9 females, with an onset age of 12 (0.04-72) months were enrolled in this study. The median time from diagnosis to transplantation was 4 (1-23) months. All patients received haplo-HSCT with a myeloablative conditioning regimen (including fludarabine, busulfan, and cyclophosphamide). Graft versus host disease (GVHD) prophylaxis was based on anti-human T lymphocyte porcine immunoglobulin/anti-human thymus globulin, methotrexate, and mycophenolate mofetil. The median observation time was 55.2 (0.3-126.2) months. By the end of follow-up, twenty patients survived and seven patients died. The 5 year overall survival rate was 73.9%. Stage I-II acute GVHD was observed in 20 patients, stage III GVHD in 1 patient and no patients had stage IV disease. Chronic GVHD was observed in 11 patients (40.7%) and was controlled by anti-GVHD therapy. CONCLUSIONS Haplo-HSCT was an effective treatment for MIOP and IOP, with a high survival rate and significantly improved clinical symptoms. For patients with a vision impairment before HSCT, the improvement was slow after transplantation. The incidence of GVHD was high but mild and was effectively controlled by appropriate treatment. These data indicated that haplo-HSCT was a feasible treatment for MIOP and IOP.

Abstract
STUDY QUESTION Are levels of trimethylamine-N-oxide (TMAO) in human follicular fluid (FF) related to IVF outcomes? SUMMARY ANSWER Higher levels of TMAO are a negative predictor of oocyte fertilization and embryo quality. WHAT IS KNOWN ALREADY TMAO is a metabolic product of dietary choline and l-carnitine produced via subsequent enzymatic modifications by the intestinal microbiota and hepatocytes. TMAO promotes inflammatory and oxidative stress pathways and has been characterized as a causative biomarker for the development of cardiometabolic disease. STUDY DESIGN, SIZE, DURATION For the present cross-sectional study, samples (FF and plasma) from 431 modified natural cycle (MNC)-IVF cycles of 132 patients were collected prospectively between October 2014 and March 2018 in a single academic medical center. PARTICIPANTS/MATERIALS, SETTING, METHODS TMAO and its precursors (choline, l-carnitine and gamma-butyrobetaine) were measured by ultra-high-performance liquid chromatography/mass spectrometry in (i) matched FF and plasma from 63 MNC-IVF cycles, in order to compare metabolite levels in the two matrices and (ii) FF from 232 MNC-IVF cycles in which only one oocyte was retrieved at follicular puncture. The association between metabolite levels and oocyte fertilization, embryo fragmentation percentage, embryo quality and the occurrence of pregnancy was analyzed using multilevel generalized estimating equations with adjustment for patient and cycle characteristics. MAIN RESULTS AND THE ROLE OF CHANCE The level of choline was higher in FF as compared to matched plasma (P < 0.001). Conversely, the levels of TMAO and gamma-butyrobetaine were lower in FF as compared to plasma (P = 0.001 and P = 0.075, respectively). For all metabolites, there was a positive correlation between FF and plasma levels. Finally, levels of TMAO and its gut-derived precursor gamma-butyrobetaine were lower in FF from oocytes that underwent normal fertilization (TMAO: odds ratio [OR] 0.66 [0.49–0.90], P = 0.008 per 1.0-μmol/L increase; gamma-butyrobetaine: OR 0.77 [0.60–1.00], P = 0.047 per 0.1-μmol/L increase) and developed into top-quality embryos (TMAO: OR 0.56 [0.42–0.76], P < 0.001 per 1.0-μmol/L increase; gamma-butyrobetaine: OR 0.79 [0.62–1.00], P = 0.050 per 0.1-μmol/L increase) than in FF from oocytes of suboptimal development. LIMITATIONS, REASONS FOR CAUTION The individual contributions of diet, gut bacteria and liver to the metabolite pools have not been quantified in this analysis. WIDER IMPLICATIONS OF THE FINDINGS More research on the contribution of diet and the effect of gut bacteria on FF TMAO is warranted. Since TMAO integrates diet, microbiota and genetic setup of the person, our results indicate potential important clinical implications for its use as biomarker for lifestyle interventions to improve fertility.

Abstract
OBJECTIVE Our study aims to investigate the correlations of micro ribonucleic acid (miR)-566 expression with the changes in immune-related indexes and differential genes in patients with intracranial aneurysm (IA). METHODS Aneurysm wall tissues from a total of 50 IA cases and the corresponding normal arterial wall tissues from 50 individuals were selected. The miR-566 expression, differential gene expression profile, and expression level of differential gene proteins were detected and analyzed by fluorescence quantitative polymerase chain reaction (qPCR), RNAseq technique and western blotting, respectively. RESULTS The miR-566 level was significantly higher in intracranial aneurysm tissues than that in normal arterial wall tissues (P<0.05). The levels of cluster of differentiation (CD)3+, CD4+, CD8+, CD4+/CD8+ and CD23+ T lymphocytes in the peripheral blood of IA patients significantly declined compared with those in the control group (P<0.05). RNAseq detection showed that there were 16 immune-inflammation-related genes significantly differentially expressed in aneurysm wall tissues compared with normal arterial wall tissues in the control group. The levels of VHL and NIK in aneurysm wall tissues were significantly decreased, while those of VEGF and ALOX5 were obviously increased. Both mRNA and protein levels of these four genes also had significant changes, which had linear relations to the expression of miR-566. CONCLUSION The abnormal expression of miR-566 affects the immune function, thus promoting the occurrence and deterioration of intracranial aneurysm.

Abstract
Objective: To investigate the clinicopathological manifestations, molecular genetic, diagnostic histology and differential diagnosis of alveolar soft part sarcoma (ASPS) in children. Methods: A total of 13 cases of ASPS diagnosed at Beijing Children's Hospital from August 2009 to November 2018 were collected. HE staining, histochemical staining for PAS and D-PAS, immunohistochemical (IHC) staining for TFE3, INI1 and CD68 and florescence in situ hybridization (FISH) for TFE3 gene translocation were performed. Results: There were four males and nine females, age ranged from 1 year and 2 months to 13 years and 8 months (mean 7.8 years); and four patients were under 5 years old. Histologically, the tumors showed a distinctive and characteristic nested or organoid growth pattern (11 cases) or solid, diffuse growth (2 cases). The tumor cells possessed abundant eosinophilic, or glycogen-rich and clear to vacuolated cytoplasm. The chromatin was relatively dispersed, with prominent and pleomorphic nucleoli; mitotic figures were rare. Vascular invasion was frequently seen. IHC staining showed specific nuclear TFE3 staining. The tumor cells were also positive for INI1,CD68 and vimentin; but were negative for MyoD1, Myogenin, CK and S-100 protein. Seven cases showed PAS and D-PAS staining, with fuchsia acicular or rod-shaped crystals in tumor cytoplasm. Nine cases showed TFE3 break-apart signals by FISH. Conclusions: ASPS is a rare soft tissue sarcoma in children. Compared with ASPA in adults, it has both similarities and unique clinicopathologic characteristics. The diagnosis needs to be confirmed by combining clinical, pathologic, IHC and genetic testing.

Abstract
Background The use of weight-adapted pediatric computed tomography (CT) tube voltage protocols has been suggested, but a consensus standard has not been established and clinical available studies are not sufficient. Purpose To determine the best tube voltage for low dose abdominal CT imaging in children. Material and Methods Eighty-seven cases who needed three CT exams in a 1–3-month interval between scans were enrolled (mean age = 4.69 ± 3.20 years). The three scans were performed with three different tube voltages at 80 kV, 100 kV, and 120 kV, keeping the same radiation dose and same contrast injection protocol. Patients were divided into five groups for analysis based on their body weight. The subjective image quality of the three exams were evaluated using a 4-point scale (4 being the best) for image noise and image quality. The objective evaluation in terms of CT values and standard deviation in aorta, liver, spleen, pancreas, and kidney were measured to calculate the degree of enhancement and contrast-to-noise ratio (CNR) of organs. One-way ANOVA was used to compare the subjective and objective image quality with respect to different tube voltages and different patient weights. Result The 80-kV tube voltage provided the highest overall enhancement and CNR for the entire patient population and the best objective image quality for the 6.1–28.0 kg subgroup. Conclusion Patient weight-dependent tube voltage selection maximizes image quality for abdominal enhanced CT in children. The optimal tube voltage for children with weight <28 kg is 80 kV; higher voltages should be selected for children weighing 28.1–50.0 kg.

Abstract
A multilocus GWAS was performed to explore the genetic architecture of four growth traits in yak. In total, 354 female yaks for which measurements of body weight (BW), withers height (WH), body length (BL) and chest girth (CG) at weaning were available underwent genotyping with the Illumina BovineHD BeadChip (770K). After quality control, we retained 98 688 SNPs and 354 animals for GWAS analysis. We identified seven, 18, seven and nine SNPs (corresponding to seven, 17, seven and eight candidate genes) associated with BW, WH, BL and CG at weaning respectively. Interestingly, most of these candidate genes were reported to be involved in growth-related processes such as muscle formation, lipid deposition, feed efficiency, carcass composition and development of the central and peripheral nervous system. Our results offer novel insight into the molecular architecture underpinning yak growth traits. Further functional analyses are thus warranted to explore the molecular mechanisms whereby these genes affect these traits of interest.

Abstract
To investigate the cognitive and psychological outcomes of pediatric allogeneic HSCT survivors in China.A total of 135 3 to 18 years old children and adolescents who underwent allo-HSCT and survived at least 3 months post-HSCT were recruited and completed the assessments. Cognitive and psychological functions were assessed via age-appropriate standardized measures. Clinical information was extracted from the medical records.Forty one 3 to 6 years old children completed Psychological Questionnaires for 3 to 6 years Children. The scores of 21(51.2%) children in cognitive development dimension, 18(43.9%) in motor development dimension, 16(39.0%) in language development and social development dimension, 15(36.6%) in emotion and will dimension and 14(34.1%) in living habits dimension were less than the standard. Fifty six 8 to 16 years old children and adolescents completed the Depression Self-rating Scale for Children and 9 (16.1%) of these met the criteria of depression. Sixty nine 7 to 16 years old children and adolescents completed the screening for Child Anxiety Related Disorders and 7 (10.1%) of these met the criteria of anxiety, especially social phobia and school phobia. Eighty nine 6 to 18 years old children and adolescents completed the Symptom Checklist-90 and 43.8% to 77.5% of these experienced mild symptoms like obsession-compulsion (77.5%), hostility (64%), and interpersonal sensitivity (60.7%). Children treated with total body irradiation (TBI) showed more cognitive impairments like motor deficits than those without TBI. Also older children and adolescents had more symptoms like psychoticism.These findings demonstrated cognitive and psychological late effects of pediatric allo-HSCT survivors in a single center in China and highlighted that the survivors conditioned with TBI had more cognitive impairments and older children and adolescents had more symptoms. Early intervention in these children and adolescents might minimize the cognitive losses and psychological effects.

Abstract
Formyl peptide receptor-2 (FPR2) has been shown to promote various tumors, but its role in colorectal cancer (CRC) has not been clearly illuminated. The aim of this study was to investigate the effect of FPR2 interference on cell proliferation, migration, invasion, apoptosis, pro-angiogenesis of CRC cells, and also the mechanisms involved. Quantitative PCR assays were applied to assess the expression levels of FPR2 in CRC tissues. CRC cell line SW1116 was chosen to perform this study. We knocked down FPR2 gene by sh-RNA. Then, the cell proliferation was assayed by soft agar colony formation assay, the cell migration capacity was checked by wound healing assay, and cell invasion ability was detected by transwell assay. In addition, flow cytometric analysis was used to detect apoptosis, while endothelial tube formation assay was used to evaluate the effects of FPR2 on pro-angiogenesis in vitro. Tumorigenesis experiment in vivo was performed in nude mice. EMT-related proteins were studied by western blotting. Quantitative PCR demonstrated that FPR2 mRNA was highly expressed in the colorectal cancer tissues. SW1116 cells' capacities of proliferation, migration, invasion, anti-apoptosis and pro-angiogenesis were distinctly suppressed after silencing FPR2 in SW1116 by sh-RNA. Suppression FPR2 mRNA in SW1116 cells suppressed tumorigenicity in nude mice. The expression of proteins related to epithelial-mesenchymal transition (EMT) such as E-cadherin, N-cadherin, Snail, Slug and vimentin was changed after suppressing FPR2. In conclusion, our study demonstrated that FPR2 could promote CRC cells progression in vitro and in vivo that may relate to promoting EMT.

Abstract
OBJECTIVE The aim of this study was to investigate the antibiofilm activity of coumarin against Candida albicans. METHODS The efficacy of coumarin against biofilm formation and the mature biofilm of C. albicans was quantified by crystal violet (CV) staining and the 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium hydroxide (XTT) reduction assay. The effect of coumarin on C. albicans adhesion was assessed on polystyrene plates and by using the cell surface hydrophobicity (CSH) assay. The morphological transition of C. albicans was conducted in two types of hyphae-inducing media at 37°C. The expression of hypha/biofilm-related genes was evaluated using qRT-PCR analysis. A rescue experiment involving addition of exogenous cyclic adenosine monophosphate (cAMP) was performed to investigate the involvement of cAMP in the yeast-to-hyphae transition. A C. albicans-infected Caenorhabditis elegans model was used to test the anti-virulence efficacy of coumarin. RESULTS Treatment with coumarin strongly affected the capacity of C. albicans to form biofilm and significantly impaired the preformed mature biofilm. The addition of coumarin notably inhibited C. albicans adhesion, CSH, and filamentation. The expression of some adhesion- and hypha-related genes, including HWP1, HYR1, ECE1, and ALS3, was remarkably down-regulated upon exposure to coumarin. Supplementation with cAMP partly rescued the coumarin-induced defects in hyphal development. Finally, coumarin prolonged survival in C. albicans-infected nematodes. CONCLUSION Coumarin inhibited C. albicans biofilm, which was associated with attenuated adhesion and hyphal growth.

Abstract
IMPORTANCE Allogeneic hematopoietic stem cell transplantation (HSCT) is considered to be the only curative treatment for familial hemophagocytic lymphohistiocytosis (FHLH). Treatment of pediatric FHLH with reduced-intensity conditioning (RIC)-based haploidentical donor (HID) HSCT has been rarely reported. OBJECTIVE To investigate outcomes and adverse events in patients with FHLH who received HID-HSCT. METHODS We conducted a retrospective study of five patients, including three with mutations in PRF1 and two with XIAP deficiency. Four of the five donors were heterozygous for these mutations. The conditioning regimen included fludarabine, cyclophosphamide, and antithymocyte globulin, with or without low-dose irradiation. Unmanipulated mobilized bone marrow and peripheral blood stem cells were used as the grafts. RESULTS All five patients were successfully engrafted. Four patients survived, and one patient died. All exhibited complete response (CR) after HSCT. All of the patients who survived exhibited CR to FHLH without severe regimen-related complications at a median of 29.5 months (range: 23-34 months) after HSCT. Four of the five patients had mixed donor chimerism. Three patients had 17% to 87% mixed donor chimerism but remained free of disease. Four patients received donor lymphocyte infusion (DLI), which improved the level of mixed donor chimerism. One patient experienced a decrease in donor chimerism to 1% and relapsed; Four patients developed acute graft-versus-host disease (GvHD) (grade I or II), and one patient developed grade IV GvHD. INTERPRETATION HID-HSCT with RIC can be considered for treatment for patients with FHLH, but the conditions and DLI regimens need to be optimized for long-term use, and more prospective studies should be conducted.
