Abstract
Marine-derived fungi of the genus Trichoderma have been surveyed for pharmaceuticals and agrochemicals since 1993, with various new secondary metabolites being characterized from the strains of marine animal, plant, sediment, and water origin. Chemical structures and biological activities of these metabolites are comprehensively reviewed herein up to the end of 2022 (covering 30 years). More than 70 strains that belong to at least 18 known Trichoderma species have been chemically investigated during this period. As a result, 445 new metabolites, including terpenes, steroids, polyketides, peptides, alkaloids, and others, have been identified, with over a half possessing antimicroalgal, zooplankton-toxic, antibacterial, antifungal, cytotoxic, anti-inflammatory, and other activities. The research is highlighted by the molecular diversity and antimicroalgal potency of terpenes and steroids. In addition, metabolic relevance along with co-culture induction in the production of new compounds is also concluded. Trichoderma strains of marine origin can transform and degrade heterogeneous molecules, but these functions need further exploration.

Abstract
One new diterpene, harziaketal A (1), and one new highly degraded sterol, trichosterol A (2), along with three known compounds, including one diterpene, harzianone (3), and two steroids, (22E,24R)-5α,6α-epoxy-ergosta-8(14),22-dien-3β,7α-diol (4) and isoergokonin B (5), were isolated from the culture of the marine-alga-epiphytic fungus Trichoderma sp. Z43 by silica gel column chromatography (CC), Sephadex LH-20 CC, and preparative thin-layer chromatography (TLC). Their structures and relative configurations were assigned by nuclear magnetic resonance (NMR) and high resolution electrospray ionisation mass spectrometry (HR-ESI-MS) data, and the absolute configuration of 1 was established by X-ray diffraction. Compound 1 features a hemiketal unit situated at the four-membered ring of harziane-type diterpenes for the first time, while 2 represents the rare occurrence of sterols with rings A and B being degraded. Compounds 1 and 2 displayed weak inhibition against the tested phytoplankton (Amphidinium carterae, Heterocapsa circularisquama, Heterosigma akashiwo, and Prorocentrum donghaiense) with half maximal inhibitory concentration (IC50 ) ranging from 14 to 53 μg/mL.

Abstract
PURPOSE/OBJECTIVE(S) Bladder carbogen and nicotinamide (BCON), combined with radiotherapy, is a standard of care in the bladder-preserving treatment of muscle-invasive bladder cancer (MIBC). UK national guidelines recommend neoadjuvant chemotherapy (NAC) before bladder preservation. However, patients did not receive NAC in the definitive phase III BCON trial. This study assessed tolerability and real-world outcomes of BCON alone or with NAC (NAC-BCON). MATERIALS/METHODS With institutional approval, demographics and clinical information were obtained for a retrospective cohort study of BCON patients (2017-2021) across 3 UK centers. Clinician-reported toxicity was assessed using RTOG grading during radiotherapy, 6 weeks and 12 months after. Cross-sectional imaging and cystoscopy determined local control, metastasis-free survival (MFS), and cancer-specific survival (CSS). Subgroup differences were compared using T and χ2 tests. Survival was analyzed by Kaplan-Meier, log-rank, and multivariate Cox proportional hazard regression. Statistical analysis was conducted using R version 4.2.1 (R Core Team (2022)). RESULTS A total of 317 patients were treated with BCON; 75 (24%) received NAC-BCON. Median follow-up was 29 months (4-63m). Patient characteristics are shown in Table 1. NAC-BCON patients were younger (median 72 vs 78 years, p<0.05), with better PS (p<0.05) and ACE-27 (p<0.05), with no statistical difference in T-staging and histopathology. 298 (94%) completed BCON, whilst 59/75 (79%) completed ≥3 cycles of NAC. There was no significant increased grade 3 acute or late bowel or bladder toxicity with NAC. 3-month cystoscopy post radiotherapy demonstrated complete response in 282/317 (89%). 121 (38%) developed metastases, and 112 (35%) died of MIBC. 5-year BCON MFS was 62% and 49% for NAC-BCON (HR 0.69, 95% CI 0.98- 2.51, p = 0.064); 5-year BCON CSS was 55% and 52% for NAC-BCON (HR 0.83, 95% CI 0.79-1.83, p = 0.39). This remained after adjusting for clinical factors in a multivariate Cox model for both MFS (p = 0.22) and CSS (p = 0.37). CONCLUSION Our real-world data compares favorably to published BCON 5-year relapse-free survival (41%) and OS (49%). NAC-BCON has no increased toxicity with comparable treatment completion rates to BCON alone. No significant improvement in survival outcomes was seen with NAC, possibly due to small numbers and patient selection in a non-randomized cohort. Further analysis is planned with additional center input.

Abstract
Further investigation of secondary metabolites of a marine-alga-derived fungus Aspergillus sp. RR-YLW-12 led to isolate one new ophiobolin-type sesterterpenoid (1), four new drimane-type sesquiterpenoids (2-5) and one natural occurring compound (6), together with seven known compounds (7-13). Their structures and stereochemistry were elucidated by extensive spectroscopic analysis of NMR and HRMS experiments, and by comparison with the literature data. All isolates were evaluated for growth inhibition of five marine harmful microalgae. The new compounds exhibited significant to moderate inhibitory effects towards all tested microalgae species with IC50 values ranging from 5.8 to 54.5 μg/mL.

Abstract
Five new lipids, tricholixins A-E (1-5), and two known terpenoids, brasilane A (6) and harzianone A (7), were discovered from a deep-sea strain (R22) of the fungus Trichoderma lixii isolated from the cold seep sediments of the South China Sea. Their structures and relative configurations were identified by meticulous analysis of MS and IR as well as NMR data. The absolute configuration of 5 was ascertained by dimolybdenum-induced ECD data in particular. Compounds 1 and 2 represent the only two new butenolides from marine-derived Trichoderma, and they further add to the structural diversity of these molecules. Although 6 has been reported from a basidiomycete previously, it is the first brasilane aminoglycoside of Trichoderma origin. During the assay against wheat-pathogenic fungi, both 1 and 2 inhibited Fusarium graminearum with an MIC value of 25.0 μg/mL, and 6 suppressed Gaeumannomyces graminis with an MIC value of 12.5 μg/mL. Moreover, the three isolates also showed low toxicity to the brine shrimp Artemia salina.

Abstract
Two new compounds, cladospolides I (1) and J (2), together with two new naturally occurring ones, methyl 11-hydroxy-4-oxododecanoate (3) and 11-hydroxy-4-oxododecanoic acid (4), were isolated from the culture extract of the cold-seep sediment-derived fungus Cladosporium cladosporioides 8-1. Their structures and configurations were established by analysis of 1D/2D NMR, MS, ECD, and specific optical rotation data. Compound 3 was possibly formed by methyl esterification of 4 during the purification process due to the utilization of methanol. All compounds were evaluated for inhibition of four marine phytoplankton species and five marine-derived bacteria.

Abstract
Eight myrochromanol analogues, including three pairs of epimers at C-2 with the myrochromanol scaffold and two examples of myrochromanol with sugar moiety linked at C-4, together with twelve trichothecene derivatives were isolated from the cultures of a shellfish-derived fungus Albifimbria verrucaria CD1-4. Among them, eight compounds named 2-epi-myrochromanol, ent-myrochromanol B, 4-epi-myrochromanol B, 2-epi-myrochromanol A, myrochromanosides A and B, 6',7'-erythro-(2'E,4'Z)-trichoverrol B, 3R,8S-dihyroxyroridin H were previously undescribed fungal metabolites. Their planar structures and relative configurations were established by 1D and 2D NMR, and HR-MS data analysis, and their absolute configurations were determined using the modified Mosher's method and electronic circular dichrosim calculations. Almost all isolates were evaluated for growth rate inhibition of three marine harmful microalgae Chattonella marina, Heterosigma akashiwo, and Prorocentrum donghaiense, and lethal activity to one marine zooplankton, Artemia salina. Myrochromanosides A and B exhibited obvious inhibitory against three tested microalgae with IC50 values in the range of 9.2-108.9 μM. 8α-Hydroxyroridin H, roridin A and verrucarin A exhibited significant inhibition against P. donghaiense with IC50 values of 6.1, 5.8, and 6.0 μM and toxicity against brine shrimp larvae with LC50 values of 1.4, 2.8, and 0.26 μM, respectively.

Abstract
AIMS We conducted a pooled analysis of four randomised controlled trials and a non-trial retrospective dataset to study the changes in serum prostate-specific antigen (PSA) concentrations during treatment and its impact on survival in men treated with docetaxel for metastatic castration-resistant prostate cancer. We also compared the outcomes and pre-treatment prognostic factors between trial and non-trial patients. MATERIALS AND METHODS Data were obtained from four randomised controlled trials and a non-trial cohort from a tertiary cancer centre. The PSA kinetics covariates chosen were absolute value (PSAT), best percentage change (BPCH) and tumour growth rate (K). The association between the covariates collected and overall survival was assessed within a Cox proportional hazards model. How well a covariate captured the difference between trial and non-trial patients was assessed by reporting on models with or without trial status as a covariate. RESULTS We reviewed individual datasets of 2282 patients. The median overall survival for trial patients was 20.4 (95% confidence interval 19.6-22.2) months and for the non-trial cohort was 12.4 (10.7-14.7) months (P < 0.001). Of the pre-treatment factors, we found that only lactate dehydrogenase fully captured the difference in prognosis between the trial and non-trial cohorts. All PSA kinetic metrics appeared to be prognostic in both the trial and non-trial patients. However, the effect size was reduced in non-trial versus trial patients (interaction P < 0.001). Of the time-dependent covariates, we found that BPCH best captured the difference between trial and non-trial patient prognosis. CONCLUSIONS The analysis presented here highlights how data from open-source trial databases can be combined with emerging clinical practice databases to assess differences between trial versus non-trial patients for particular treatments. These results highlight the importance of developing prognostic models using both pre-treatment and time-dependent biomarkers of new treatments.

Abstract
Objective: To analyze the influence of the free nutritious lunch policy on the risk of overweight in rural adolescents in China. Methods: Based on the data of China Education Panel Survey Junior High School Cohort from 2013 to 2016, this paper analyzes the influence of the policy on overweight risk in adolescents in rural China with logistic model, and a total of 3 453 rural teenagers were included. Results: Adolescents who received free lunch in the first year of junior high school had a 35.8% (P<0.05) and 31.6% (P<0.05) lower risk of being overweight in the second year and one year after junior high school graduation than those who didn't. Also, adolescents who received free lunch in the second year of junior high school had a 36.7% (P<0.05) and 29.9% (P<0.05) lower risk of being overweight in the third grade and one year after graduation than those who didn't. There was no statistically significant difference in the risk of being overweight one year after the graduation between adolescents who received free lunch in third year and those who didn't. And boys benefited more from this policy than girls. Conclusions: The free nutrition lunch policy has long term effect to reduce the likelihood of being overweight for adolescents, and the impact has a cumulative effect. This suggests that the free nutrition lunch policy is effective in promoting health of adolescents in terms of overweight.

Four new carotane sesquiterpenoids, byssocarotins A-D (1-4), two new nor-sesquiterpenoids, byssofarnesin (5) and byssosesquicarin (6), and three new polyketides, byssoketides A and B (7 and 8) and (8R)-paecilocin A (9a), were obtained from a macroalga-associated strain (RR-dl-2-13) of the fungus Byssochlamys spectabilis. These isolates were identified by a combination of spectroscopic methods, including mass spectroscopy, nuclear magnetic resonance, electronic circular dichroism, and X-ray diffraction. Compounds 1-4 greatly contribute to the diversity of rarely occurring 2,15-epoxycarotane sesquiterpenoids, while 5 and 6 are degradation products of farnesane and sesquicarane precursors, respectively. Compound 7 is a structurally unique furan fatty acid derivative that possesses an aldehyde group and a large conjugated unit, and 8 features a hemiketal group. During antimicrobial assays, 8 showed antagonism against the phytopathogenic fungi Glomerella cingulata, Fusarium oxysporum f. sp. cucumerium, and F. oxysporum f. sp. cubense and the marine-derived bacteria Vibrio parahaemolyticus and V. harveyi with MIC values of 13 to 50 μg/mL.

Abstract
The clinical data of five cases of relapsed/refractory (R/R) Philadelphia chromosome-positive acute B-lymphocytic leukaemia (Ph+B-ALL) treated with Bcl-2 inhibitor venetoclax combined with tyrosine kinase inhibitor (TKI) and dexamethasone-containing low-dose chemotherapy regimen at Zhengzhou University Cancer Hospital were analyzed, and the efficacy and safety were evaluated. Ponatinib was used in two of the five patients with T315I mutation, and flumatinib was used in other three patients. The results showed that, of the four minimal residual disease (MRD) positive patients, three achieved complete molecular remission (CMR) in the short term and one was ineffective. Another patient with morphological recurrence reached CR in one month. The overall response rate was 80%. Treatment related adverse reactions included mild skin pigmentation, gastrointestinal reactions, fatigue, and grade Ⅰ-Ⅱ bone marrow suppression.

Abstract
The case is presented on a 33-year-old woman with sudden vision loss for more than 20 days without a history of steroid use either locally or systemically. There was a history of connective tissue disease. The fundus fluorescein angiogram and optical coherence tomography showed multiple central serous chorioretinopathy (CSC) complicated by exudative retinal detachment (ERD). Meanwhile, the computed tomography of the adrenal suggested an adrenal adenoma. After complete tumor resection, the visual and anatomical functions of this patient have been significantly improved. Moreover, recurrence of CSC complicated by ERD was not observed during 9 months clinical follow-up after surgery. (Chin J Ophthalmol, 2021, 57: 784-786).

Abstract
The ability to manipulate quantum systems lies at the heart of the development of quantum technology. The ultimate goal of quantum control is to realize arbitrary quantum operations (AQUOs) for all possible open quantum system dynamics. However, the demanding extra physical resources impose great obstacles. Here, we experimentally demonstrate a universal approach of AQUO on a photonic qudit with the minimum physical resource of a two-level ancilla and a log_{2}d-scale circuit depth for a d-dimensional system. The AQUO is then applied in a quantum trajectory simulation for quantum subspace stabilization and quantum Zeno dynamics, as well as incoherent manipulation and generalized measurements of the qudit. Therefore, the demonstrated AQUO for complete quantum control would play an indispensable role in quantum information science.

Abstract
Ten new bisabolane derivatives, trichobisabolins Q-Z (1-10), one new cadinane derivative, cadin-4-en-11-ol (11), and three new cyclonerane derivatives, cycloner-3-en-7,11-diol (12), isoepicyclonerodiol oxide (13), and norepicyclonerodiol oxide (14), were isolated from the endophytic fungal strain RR-dl-6-11 of Trichoderma asperelloides that was obtained from a marine alga. Their structures along with relative configurations were established mainly by NMR and IR as well as MS techniques, and the absolute configurations of 10 and 11 were assigned by ECD and X-ray diffraction data, respectively. Sesquiterpenes from the fungus T. asperelloides are reported for the first time. It is interesting that half of the bisabolane derivatives are demethylated. Compound 12 represents the first the occurrence of cyclopentenyl-bearing cycloneranes, and 14 seems a cyclopentyl-degrading cyclonerane derivative. Several isolates feature potent inhibition of marine phytoplankton species.

Abstract
To analyze the prognostic factors of extramedullary relapse (EMR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute lymphoblastic leukemia (ALL).The clinical data of 33 relapsed patients in 95 ALL patients receiving allo-HSCT were analyzed retrospectively. The median time of relapse was 5.7 (0.7-52.3) months. Extramedullary relapse was recorded in 10 cases (10.5%), bone marrow relapse in 15 cases (15.8%), and both extramedullary and marrow relapse were seen in 8 cases (8.4%). The median time of EMR was 7.4(0.7-52.3) months. The most commonly involved organ was central nervous system, followed by testis and bone. The 3-year OS rate in EMR patients was (33.3±11.1) %. Univariate analysis showed that disease state before transplantation (P=0.026), extramedullary infiltration before transplantation (P=0.005), conditioning regimens (P=0.033) and acute graft-versus-host disease(aGVHD) (P=0.013) were significantly correlated with EMR. Multivariate analysis suggested that extramedullary infiltration (RR=5.067, 95%CI1.542-16.645, P=0.007) and aGVHD(RR=3.585, 95%CI1.245-10.320, P=0.018) were independent predictive factors of EMR in ALL patients after allo-HSCT.

Abstract
Digital quantum simulators provide a diversified tool for solving the evolution of quantum systems with complicated Hamiltonians and hold great potential for a wide range of applications. Although much attention is paid to the unitary evolution of closed quantum systems, dissipation and noise are vital in understanding the dynamics of practical quantum systems. In this work, we experimentally demonstrate a digital simulation of an open quantum system in a controllable Markovian environment with the assistance of a single ancillary qubit. By Trotterizing the quantum Liouvillians, the continuous evolution of an open quantum system is effectively realized, and its application in error mitigation is demonstrated by adjusting the simulated noise intensities. High-order Trotter for open quantum dynamics is also experimentally investigated and shows higher accuracy. Our results represent a significant step toward hardware-efficient simulation of open quantum systems and error mitigation in quantum algorithms in noisy intermediate-scale quantum systems.

Abstract
Six new sesquiterpenoids including three bisabolane derivatives, trichobisabolins O1, O2, and P (1-3), two nerolidol derivatives, trichonerolins A and B (4 and 5), one acorane, trichoacorin A (6), along with one new steroid, isoergokonin B (7), were isolated from the culture of Trichoderma brevicompactum A-DL-9-2 obtained from the inner tissue of the red alga Chondria tenuissima. Their structures and relative configurations were assigned by interpretation of 1D/2D NMR and MS data. As acyclic sesquiterpenoids, compounds 4 and 5 were discovered from Trichoderma for the first time. Compounds 1-7 were evaluated for the inhibition of some marine-derived organisms, in which, 3 and 4/5 exhibited potent inhibition against Amphidinium carterae and Chattonella marina with IC50 of 1.8 μg/mL and 1.2 μg/mL, respectively. In addition, compound 7 could inhibit the growth of Pseudoalteromonas citrea with an MIC value of 64 μg/mL.

Abstract
One new proharziane and three new harziane derivatives (1-4) together with six known ones (5-10) were isolated from the marine-alga-derived ascomycete Trichoderma asperelloides RR-dl-6-11. Their structures and relative configurations were determined via spectroscopic techniques, and the absolute configurations were ascertained by analysis of ECD curves. This is the first report on the secondary metabolites of T. asperelloides, and the new isolates (1-4), especially seco-harziane 4, greatly add to the structural diversity of harziane diterpenes as well as their precursors and catabolites. Compounds 1-5 inhibited four marine phytoplankton species, and the structure-activity relationship of harziane derivatives is analyzed.

Abstract
Radiotherapy plays an essential role in the curative treatment of muscle-invasive bladder cancer (MIBC). Hypoxia affects the response to MIBC radiotherapy, limiting radiocurability. Likewise, hypoxia influences MIBC genetic instability and malignant progression being associated with metastatic disease and a worse prognosis. Hypoxia identification in MIBC enables treatment stratification and the promise of improved survival. The most promising methods are histopathological markers such as necrosis; biomarkers of protein expression such as HIF-1α, GLUT-1 and CAIX; microRNAs; and novel mRNA signatures. Although hypoxia modification can take different forms, the gold standard remains carbogen and nicotinamide, which improve local control rates in bladder preservation and absolute overall survival with no significant increase in late toxicity. This is an exciting time for evolving therapies such as bioreductive agents, novel oxygen delivery techniques, immunotherapy and poly (ADP-ribose) polymerase 1 (PARP) inhibitors, all in development and representing upcoming trends in MIBC hypoxia modification. Whatever the future holds for hypoxia-modified radiotherapy, there is no doubt of its importance in MIBC. mRNA signatures provide an ideal platform for the selection of those with hypoxic tumours but are yet to qualified and integrated into the clinic. Future interventional trials will require biomarker stratification to ensure optimal treatment response to improve outcomes for patients with MIBC.

Abstract
Carotane sesquiterpenes are commonly found in plants but are infrequently reported in the fungal kingdom. Chemical investigation of Trichoderma virens QA-8, an endophytic fungus associated with the inner root tissue of the grown medicinal herb Artemisia argyi H. Lév. and Vaniot, resulted in the isolation and characterization of five new carotane sesquiterpenes trichocarotins I-M (1-5), which have diverse substitution patterns, and seven known related analogues (6-12). The structures of these compounds were established on the basis of a detailed interpretation of their NMR and mass spectroscopic data, and the structures including the relative and absolute configurations of compounds 1-3, 5, 9, and 10 were confirmed by X-ray crystallographic analysis. In the antibacterial assays, all isolates exhibited potent activity against Escherichia coli EMBLC-1, with MIC values ranging from 0.5 to 32 µg/mL, while 7β-hydroxy CAF-603 (7) strongly inhibited Micrococcus luteus QDIO-3 (MIC = 0.5 µg/mL). Structure-activity relationships of these compounds were discussed. The results from this study demonstrate that the endophytic fungus T. virens QA-8 from the planted medicinal herb A. argyi is a rich source of antibacterial carotane sesquiterpenes, and some of them might be interesting for further study to be developed as novel antibacterial agents.

Abstract
Objective: To explore the relationship between the expression of neuropilin-1 (NRP-1) on Treg cells and its ligands semaphorins-3A (Sema3A) , transforming growth factor-β(1) (TGF-β(1)) as well as the balance of type 1 helper T cells (Th(1)) and type 2 helper T cells (Th(2)) cells. Methods: This study enrolled 62 patients with immune thrombocytopenia (ITP; 33 and 29 newly diagnosed and chronic ITP, respectively) from March 2014 to May 2015. Consequently, 30 healthy people in the same period were selected as the normal control group. The expression of NRP-1 in Treg cells was detected via flow cytometry. The Sema3A, TGF-β(1), IFN-γ, and IL-4 levels in plasma were detected by enzyme-linked immunosorbent assay. The real-time polymerase chain reaction technique was used to detect the mRNA expression levels of NRP-1, Sema3A, and TGF-β(1). The one-way analysis of variance and independent sample t-test was used for comparison between three and two groups, respectively. Correlations among the mRNA expression levels of NRP-1, Sema3A, and TGF-β(1) were assessed via Spearman correlation coefficients. Results: Treg cells in the newly diagnosed ITP group significantly increased compared with those in the chronic ITP and normal control groups. The expression of NRP-1 decreased[ (0.15 ± 0.03) %, (0.33 ± 0.15) %, and (0.46 ± 0.06) %; P<0.01], the plasma Sema3A level increased[ (8.10 ± 1.32) μg/L, (7.41±1.30) μg/L, and (2.88±0.82) μg/L; P<0.01], and the plasma TGF-β(1) level decreased[ (16.50±3.36) μg/L, (35.17±10.26) μg/L, and (41.00±10.02) μg/L; P<0.01]. Moreover, the level of plasma IFN-γ increased[ (17.21+2.80) ng/L, (10.23+1.59) ng/L, and (8.18+3.27) ng/L; P<0.01], and the ratios of Th(1)/Th(2) (IFN-γ/IL-4) increased (1.29±0.30, 0.72±0.16, and 0.61±0.27; P<0.01) . The mRNA expressions of NRP-1 and Sema3A in the newly diagnosed ITP and chronic ITP groups were lower than that in the normal control group (P<0.01) . Consequently, the NRP-1 mRNA expression was positively correlated with Sema3A and TGF-β(1) mRNA expression in the newly diagnosed ITP group. Conclusion: NRP-1 played an essential role in the pathogenesis of ITP.

Abstract
Quantum correlations in observables of multiple systems not only are of fundamental interest, but also play a key role in quantum information processing. As a signature of these correlations, the violation of Bell inequalities has not been demonstrated with multipartite hybrid entanglement involving both continuous and discrete variables. Here we create a five-partite entangled state with three superconducting transmon qubits and two photonic qubits, each encoded in the mesoscopic field of a microwave cavity. We reveal the quantum correlations among these distinct elements by joint Wigner tomography of the two cavity fields conditional on the detection of the qubits and by test of a five-partite Bell inequality. The measured Bell signal is 8.381±0.038, surpassing the bound of 8 for a four-partite entanglement imposed by quantum correlations by 10 standard deviations, demonstrating the genuine five-partite entanglement in a hybrid quantum system.

Abstract
Objective: To investigate the clinicopathologic features, treatment, and prognosis in patients with Castleman disease (CD) . Methods: We retrospectively analyzed the clinicopathologic data of 59 patients for whom a diagnosis of Castleman disease was confirmed using pathological examination from October 2011 to October 2019 at the Henan Cancer Hospital. The patients were divided into the following two groups as per the following clinical classifications: unicentric CD (UCD, n=47) and multicentric CD (MCD, n=12) . Data on clinical manifestations, laboratory findings, treatment, and prognosis were analyzed. Results: There was no significant difference in the median age and the ratio of male to female between the UCD and MCD. UCD was characterized by asymptomatic enlargement of the single lymph node. The main pathological type was hyaline vascular histopathology (83.0%) . Of these, 44 patients chose surgical resection, and their prognosis was good. Treatment. MCD was characterized by multiple enlarged superficial and/or deep lymph nodes with B symptoms, weakness, and hepatosplenomegaly. Anemia, hypoproteinemia, and globulin level were increased on laboratory examinations. Plasmacyte histopathology was the main pathological type and was present in about 50.0% of the subjects. Only chemotherapy was performed for these MCD patients, followed by chemotherapy or chemotherapy followed by radiotherapy, and the efficient was 58.3% (7/12) . Conclusions: UCD, characterized by asymptomatic enlargement of the single lymph node, shows good postoperative prognosis. MCD has relatively complex clinical manifestations and poor prognosis, and optimal treatment is yet to be established.

目的 探讨急性髓系白血病(AML)的克隆异质性特征及其临床价值。 方法 采用高通量测序技术靶向检测2016年1月至2019年6月河南省肿瘤医院收治的465例AML患者的68种相关基因,将检出的基因突变位点根据变异等位基因频率(VAF)及同期流式细胞学结果进行克隆异质性分析,并分析其与预后的关系。 结果 338例(81.4%)初诊患者检出基因突变,其中携带DNMT3A、NRAS和RUNX1突变患者出现2个及以上克隆比例显著增加(DNMT3A:χ2=15.231, P<0.001;NRAS:χ2=19.866, P<0.001;RUNX1:χ2=23.647, P<0.001)。不同年龄组间克隆数差异有统计学意义(χ2=17.505, P=0.022),其中>60岁患者携带2个和≥3个克隆的比例增加。初诊患者与复发或继发AML患者间克隆分布差异具有统计学意义(χ2=11.302, P=0.010),且患者多克隆的比例随预后危险度增加而逐渐增加(χ2=17.505, P=0.022)。而主克隆分析中,RUNX1突变标志的主克隆比例较高(χ2=4.527, P=0.033)。克隆异质性与疗效相关分析显示,携带3个及以上克隆患者的总生存(OS)期和无进展生存(PFS)期均远低于其他患者(OS:χ2=13.533,P=0.004;PFS:χ2=9.817,P=0.020),而在中危组患者中,克隆数目多的患者其PFS期显著缩短(χ2=10.883,P=0.012)。Cox回归多因素分析显示,携带3个及以上克隆为影响预后的独立危险因素,其OS期和PFS期显著短于无克隆患者(OS:HR=3.296,95%CI 1.568~6.932,P=0.002;PFS:HR=3.241,95%CI 1.411~7.440,P=0.006)。 结论 克隆异质性可反映肿瘤的生物学特性,提示其耐药性、难治性及侵袭性,可进一步用来评估疗效和AML中危组患者的预后。

Abstract
Eight cadinane derivatives, trichocadinins H - N (1-7) and methylhydroheptelidate (8), and two carotane derivatives, 14-O-methyltrichocarotin G (9) and 14-O-methyl CAF-603 (10), including eight new ones (1-6, 9, and 10), were isolated from the culture of Trichoderma virens RR-dl-6-8 obtained from the organohalogen-enriched marine red alga Rhodomela confervoides. Their structures and relative configurations were established by analysis of NMR and mass spectroscopic data, and the absolute configurations were assigned on the basis of ECD curves, highlighted by the ECD diversity of carboxylic acid derivatives. Among the isolates, 1 with a halogen atom and 8, a new naturally occurring compound, are 2,3-seco-cadinane sesquiterpenes, and the epimeric 2 and 3 feature a 2-nor-cadinane skeleton. A commercially-sourced compound with the same planar structure as that of 7 has been reported in a patent, but its configuration was not given. Compounds 1-10 exhibited growth inhibition of some marine phytoplankton species.

Abstract
Objective: To explore the characteristics and clinical significance of clonal heterogeneity in patients with acute lymphoblastic leukemia(ALL). Methods: From January 2016 to June 2019, 170 newly diagnosed ALL patients were enrolled in the Department of Hematology, Henan Cancer Hospital, including 93 males and 77 females, with a median age of 17 (2-80) years. Fifty-two ALL-related genes were detected by high-throughput sequencing technique. The clonal heterogeneity of mutations was analyzed according to the variant allele frequency (VAF) and the results of flow cytometry. The prognostic value of mutations was also evaluated. Results: Gene mutations were detected in 121 (71.2%, 121/170) patients, of which 2 or more clones were detected in 18 (52.9%, 18/34) T-cell acute lymphoblastic leukemia patients, while only 23 (16.9%, 23/136) B-cell acute lymphoblastic leukemia patients were positive of multiple mutations (P<0.01).Gene mutation-related clonal heterogeneity analysis showed that 2 or more clones were frequent in patients with NOTCH1 mutations (13/19 patients) (P<0.01). Event free survival (EFS) in patients with 3 or more clones was significantly lower than other patients (χ(2)=10.330, P=0.016). Child ALL patients had similar result, that multiple clones predicted lower overall survival (OS) and EFS (OS: χ(2)=7.974, P=0.047; EFS: χ(2)=10.860, P=0.013). Conclusion: Clonal heterogeneity in ALL patients is closely related to the different origin of lymphocyte lineages and the age of onset, which may reveal the nature of the disease and predict the clinical outcome.

Abstract
Using geometric phases to realize noise-resilient quantum computing is an important method to enhance the control fidelity. In this work, we experimentally realize a universal nonadiabatic geometric quantum gate set in a superconducting qubit chain. We characterize the realized single- and two-qubit geometric gates with both quantum process tomography and randomized benchmarking methods. The measured average fidelities for the single-qubit rotation gates and two-qubit controlled-Z gate are 0.9977(1) and 0.977(9), respectively. Besides, we also experimentally demonstrate the noise-resilient feature of the realized single-qubit geometric gates by comparing their performance with the conventional dynamical gates with different types of errors in the control field. Thus, our experiment proves a way to achieve high-fidelity geometric quantum gates for robust quantum computation.

Abstract
Objective: To investigate the relationship between gene mutation characteristics, mutation burden and general condition, disease subtype and karyotype of patients with myelodysplastic syndrome (MDS), and its clinical value. Methods: High-throughput sequencing was used to detect 65 blood tumor-related genes in 191 MDS patients and 9 secondary acute myelocytic leukemia patitents(SAML), and to analyze the characteristics of abnormal genes, mutation burden, as well as the relationship with disease subtypes, chromosome karyotypes and age. Results: Mutations were found in 148 patients (77.5%), including 47 abnormal genes and 186 mutation sites. And gene mutations were found in 9 SAML patients, the number of mutations was significantly higher than that in MDS patients (χ(2)=11.911, P=0.018). Among the abnormal genes, the mutation frequency of U2AF1 (37.3%) and ASXL1 (41.6%) were higher, and there were significant differences in mutation burden among different abnormal genes (F=91.946, P<0.001). There were differences in the number of gene mutations among different subtypes of MDS, and the number of EB-2 gene mutations was the highest (2.2±1.5). In SLD, MLD, EB-1 and EB-2, the proportion of carrying ≥ 3 mutations increased gradually (χ(2)=52.471, P=0.037). TP53 mutation was associated with abnormal karyotype (r(φ)=0.177, P=0.019), especially with complex karyotype (r(φ)=0.440, P<0.001), while NPM1 mutation is associated with normal karyotype (r(φ)=0.173, P=0.024). The number of mutations carried by patients under 30 years old was the least, and the number of mutations increased with the increase of age. The number of mutations was the most in patients aged 60 to 79 years old (P=0.017), and the mutation frequency of epigenetic related genes increased with the increase of age (P=0.041). Conclusions: The mutation characteristics and mutation load of MDS-related genes are closely related to clinical factors such as disease subtype, chromosome karyotype and patient age.

Abstract
To realize fault-tolerant quantum computing, it is necessary to store quantum information in logical qubits with error correction functions, realized by distributing a logical state among multiple physical qubits or by encoding it in the Hilbert space of a high-dimensional system. Quantum gate operations between these error-correctable logical qubits, which are essential for implementation of any practical quantum computational task, have not been experimentally demonstrated yet. Here we demonstrate a geometric method for realizing controlled-phase gates between two logical qubits encoded in photonic fields stored in cavities. The gates are realized by dispersively coupling an ancillary superconducting qubit to these cavities and driving it to make a cyclic evolution depending on the joint photonic state of the cavities, which produces a conditional geometric phase. We first realize phase gates for photonic qubits with the logical basis states encoded in two quasiorthogonal coherent states, which have important implications for continuous-variable-based quantum computation. Then we use this geometric method to implement a controlled-phase gate between two binomially encoded logical qubits, which have an error-correctable function.

Objective: To explore the relationship between driver gene mutation (JAK2, MPL and CALR) and disease type in BCR-ABL negative myeloproliferative neoplasms (MPNs) including primary myeloid fibrosis (PMF), essential thrombocytosis (ET) and polycythemia vera (PV). Methods: A total of 32 MPN related genes were detected by high-throughput sequencing in 156 MPN patients. The relationships between disease type and patients' general performance, the characteristics of driver gene mutations, concomitant gene mutations were analyzed. Results: In the population with JAK2 V617F positive mutation, the proportion of patients over 60 years old in PMF was higher than that with ET or PV. By high-throughput sequencing, 22 concomitant gene mutations were detected in 46 patients with JAK2, MPL or CALR mutations, including 4 (8.3%) in PV, 20 (29.4%) in ET, and 22 (55.0%) in PMF. DNMT3A mutation was detected only in patients with PV, while splicing factor related genes including SF3B1, SRSF2 and U2AF1 were only accompanied by PMF. According to the variation allele frequency (VAF) value of JAK2 V617F mutation, the VAF value associated with PV was the highest (68.15%), followed by PMF (37.7%) and ET (23%). However, there were significant differences in the incidence of JAK2 V617F homozygous among 3 different diseases. In patients with JAK2 mutation, the proportion of other gene mutations in PV and ET was significantly lower than that in PMF. Conclusions: Under the condition of common driver gene mutations (JAK2, MPL and CALR), patients' age, VAF value and homozygous state, concomitant gene mutations are closely related to different disease type. These correlations help to improve clinical understanding of disease characteristics and risk assessment.

Abstract
Objective: To investigate the safety and efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) containing cladribine sequential busulfan regimen for refractory/relapsed acute myeloid leukemia (AML) . Methods: The clinical data of 12 refractory/relapsed AML patients received allo-HSCT with cladribine sequential busulfan regimen. Results: ① Of the 12 patients, 9 were males and 3 females, with a median age of 36 (27-50) years. The donors were identical sibling (3) , matched unrelated (1) and haploidentical family member (9) respectively. Nine patients reached partial remission and other remained no remission after chemotherapy before allo-HSCT. The median previous chemotherapy courses before allo-HSCT were 6 (2-13) . ② Conditioning regimen: Smostine 250 mg·m(-2)·d(-1), d-7; Cladribine 5 mg·m(-2)·d(-1), d-6 to d-2; Cytarabine Arabinoside 2 g·m(-2)·d(-1), d-6 to d-2; Busulfan 3.2 mg·m(-2)·d(-1), d-6 to d-3; Rabbit anti-human thymocyte immunoglobulin (ATG) 1.5 mg·m(-2)·d(-1) (unrelated donor transplantation) or 2.0-2.5 mg·m(-2)·d(-1) (haplo-HSCT) , d-4 to d-1. ③ Of the 12 patients, 11 patients attained complete haploidentical engraftment, one case occurred primary graft failure. The median durations for neutrophils and platelet implantations were 15 (15-21) and 19 (17-30) days respectively. ④After conditioning, no hepatic veno-occlusive diseases were observed, hemorrhagic cystitis occurred in 2 patients, 8 patients had fever, 3 cases experienced acute GVHD grade II, localized chronic GVHD occurred in 8 patients. ⑤The median follow-up was 8 (4-12) months. Leukemia relapse occurred in 2 patients at time of 6, 12 months after allo-HSCT. The estimated 1-year OS and DFS were (71.1±1.8) % and (62.2±1.8) %, respectively. Conclusions: allo-HSCT with cladribine sequential busulfan regimen was a feasible choice with favorable outcome for refractory/relapsed AML.

Abstract
To retrospectively analyze the safety and efficacy of low dose subcutaneous decitabine combined with arsenic trioxide in patients with intermediate or high-risk myelodysplastic syndrome (MDS). Three of the total 11 MDS patients achieved complete remission (CR) and 6 achieved hematological improvement (HI), 1 stable disease (SD), and 1 progressive disease (PD). One patient was treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). The median follow-up time was 413(90-1 275) d. Nine patients were still alive. Low dose subcutaneous decitabine combined with arsenic trioxide can be an alternative regimen for intermediate or high-risk MDS patients.

Abstract
Deterministic quantum computation with one qubit (DQC1) is iconic in highlighting that exponential quantum speedup may be achieved with negligible entanglement. Its discovery catalyzed a heated study of general quantum resources, and various conjectures regarding their role in DQC1's performance advantage. Coherence and discord are prominent candidates, respectively, characterizing nonclassicality within localized and correlated systems. Here we realize DQC1 within a superconducting system, engineered such that the dynamics of coherence and discord can be tracked throughout its execution. We experimentally confirm that DQC1 acts as a resource converter, consuming coherence to generate discord during its operation. Our results highlight superconducting circuits as a promising platform for both realizing DQC1 and related algorithms, and experimentally characterizing resource dynamics within quantum protocols.

Abstract
Objective: To evaluate the efficacy and safety of mesenchymal stem cells in allogeneic hematopoietic stem cell transplantation for patients with refractory severe aplastic anemia (R-SAA) . Method: The clinical data of 25 R-SAA patients receiving co-transplantation of mesenchymal stem cells combined with peripheral blood stem cells from sibling donors (10 cases) and unrelated donors (15 cases) from March 2010 to July 2018 in Zhengzhou University Affiliated Tumor Hospital were retrospectively analyzed. Antithymocyte globulin (ATG) treatment was ineffective/relapsed in 11 cases, and cyclosporine (CsA) treatment ineffective/relapsed in 14 cases. Results: There were 13 male and 12 female among these patients. One patient had a primary graft failure, one patient had a poorly engraftment of platelets, and the remaining 23 patients achieved hematopoietic engraftment. The median time of granulocyte engraftment was 12.5 (10-23) days and 15 (11-25) days for megakaryocyte. Incidences of grade Ⅰ/Ⅱ acute graft-versus-host disease (aGVHD) and chronic graft-versus-host disease (cGVHD) were 37.5% (9/24) and 21.7% (5/23) , respectively. There was no severe GVHD and no severe complications that related to transplantation. 21 of 25 (84%) patients were alive with a median follow-up of 22.9 (1.6-107.8) months. The 5-year overall survival rate after transplantation was (83.6±7.5) %. Conclusion: The combination of mesenchymal stem cells is reliable and safe in the treatment of R-SAA in peripheral blood stem cell transplantation of unrelated donors and sibling donors, which could significantly reduce the incidence of GVHD and severe transplantation-related complications.

Abstract
The efficacy and safety of co-transplantation of unrelated donor peripheral blood stem cells (UD-PBSCs) combined with umbilical cord mesenchymal stem cells (UC-MSCs) in refractory severe aplastic anemia-Ⅱ(RSAA-Ⅱ) were analyzed retrospectively. Fifteen patients with RSAA-Ⅱ underwent UD-PBSCs and UC-MSCs co-transplantation, among whom 14 cases had hematopoietic reconstitution without severe graft versus-host disease (GVHD). The 5-year overall survival rate was 78.57%. Combination of UD-PBSCs and UC-MSCs transplantation could be a safe and effective option for RSAA-Ⅱ.

Abstract
Objective: To investigate the influence of additional clonal chromosome abnormalities in Ph negative cells (CCA/Ph(-)) on the efficacy of chronic myeloid leukemia (CML) after tyrosine kinase inhibitors (TKI) treatment. Methods: The clinical data of 28 CML patients with CCA/Ph(-) treated in Henan Cancer Hospital from July 2014 to December 2017 were analyzed retrospectively. The univariate analysis was carried out by Kaplan-Meier method. Multivariate analysis was done by Cox proportional risk model. Results: A total of 28 CCA/Ph(-)patients were recruited including 17 males and 11 females with median age of 42.5 years old. The most common CCA/Ph(-)were trisomy 8 (60.7%), monosomy 7 (14.3%). 64.3% CCA/Ph(-)were transient and 35.7% recurrent (more than 2 times). Cytopenia in two or three lineages of peripheral blood was seen in 42.9% patients. As to the efficacy, 89.3% patients achieved major cytogenetic response (MCyR), 25% with major molecular response (MMR). The median follow-up time was 26.5 months. Treatment failure (TF) of TKI occurred in 32.1% patients with median duration of response 8 (1-41) months. Univariate analysis showed that TF rate was significantly correlated with the frequency of CCA/Ph(-)and cytopenia (all P<0.05). The MMR rate was also significantly correlated with cytopenia (P<0.05). Cytopenia of two lineages or pancytopenia was an independent risk factor related to MMR rate (RR=3.868, 95%CI 1.216-12.298, P=0.022) . Conclusions: Cytopenia in CCA/Ph(-)appears to be an independent risk factor of MMR in CML patients with TKI treatment. The recurrent CCA/Ph(-)may link to higher treatment failure rate. Drug withdrawal or alternative strategy should be considered according to response and the ABL kinase mutations.
