Abstract
OBJECTIVE To investigate the accuracy of next-generation sequencing technology (NGS) in detecting the polymorphisms of HLA-DRB1, DQB1, DQA1, DRB3, DRB4, DRB5, DPA1 and DPB1 alleles in randomly-selected unrelated healthy individuals from Shenzhen Han population, investigate the potential reason for HLA-DRB1 allele dropout in routine NGS, and establish an internal quality control system. METHODS NGS-based HLA class II genotyping was performed on 1 012 samples using the MiSeqDxTM platform. The suspected missed alleles indicated by the quality control software and HLA-DRB1 homozygotes were confirmed by PCR-SSOP or PCR-SBT methods. RESULTS A total of 139 alleles were detected, including HLA-DRB1(45), DRB3(7), DRB4(5), DRB5(7), DQA1(17), DQB1(21), DPA1(10) and DPB1(27). HLA-DRB1*09:01(17.09%),15:01(10.72%); DRB3*02:02(25.99%),03:01(10.18%); DRB4*01:03(36.46%); DRB5*01:01(15.42%); DQA1*01:02(20.01%),03:02(17.19%); DQB1*03:01(19.47%),03:03(17.98%), 05:02(11.66%), 06:01(10.67%); DPA1*02:02(54.45%), 01:03(31.18%) and DPB1*05:01(39.13%), 02:01(16.90%) alleles were the most common alleles in Shenzhen Han population (frequencies >10%). There was no statistical difference between the gene frequencies of HLA-DRB1 and DQB1 loci in our study. The HLA Common and Well-Documented Alleles in China (CWD2.4) (χ2=12.68, P >0.05). 94 cases of HLA-DRB1 homozygous samples detected by NGS were retested by PCR-SSOP or SBT method, and one case of allele dropout at HLA-DRB1 locus was found. SBT method confirmed that the allele of DRB1*04:03 was missed. The laboratory internal quality control system was established. Two cases of new alleles were detected and named by WHO Nomenclature Committee for Factors of the HLA System. CONCLUSION The HLA genotyping results based on NGS showed a significantly lower ambiguity rate. The HLA class II alleles exhibit genetic polymorphism in the Han population of unrelated healthy individuals in Shenzhen. The independent method based on NGS in clinical histocompatibility testing has limitations and requires internal quality control strategies to avoid allele-dropout events.

Abstract
BACKGROUND Liver hepatocellular carcinoma (LIHC) is a serious liver disease worldwide, and its pathogenesis is complicated. AIMS This study investigated the potential role of FANCA in the advancement and prognosis of LIHC. METHODS Public databases, quantitative reverse transcription polymerase chain reaction (qRT-PCR), western blot (WB) and immunohistochemistry (IHC) were employed to measure FANCA expression between tumor and normal samples. The relationship between FANCA expression and prognosis of LIHC patients were examined. Functional enrichment of FANCA-related genes was performed. Furthermore, univariate and multivariate analyses were conducted to determine the independent prognosis value of FANCA in LIHC. Finally, influence of FANCA knockout on the proliferation, migration, and invasion of HepG2 cell was validated with cloning formation, CCK8, and Transwell assays. RESULTS Expression analysis presented that FANCA had high expression level in LIHC tissues and cells. Receiver operating characteristic (ROC) curve analysis showed that FANCA was of great diagnosis value in LIHC. Clinicopathological analysis revealed that FANCA was significantly greater expressed in the advanced stage than in the early stage of LIHC. Univariate, multivariate, and Kaplan-Meier survival analysis confirmed that high expression of FANCA was strongly associated with poor survival of LIHC patients. In addition, high level of FANCA in LIHC showed a negative association with immunoinfiltrated B cells, T cells, and stromal scores. Moreover, Knockout of FANCA significantly inhibited HepG2 cell proliferative activity, migration, and invasion ability. CONCLUSIONS Our data revealed that high level of FANCA was closely associated with LIHC malignant progression, suggesting its potential utility as a diagnostic, predictive indicator, and therapeutic target.

Abstract
Objective: To investigate the efficacy and safety in relapsed and refractory multiple myeloma (RRMM) patients with combination regimen of daratumumab. Methods: The clinical data of 42 RRMM patients admitted to Qingdao Municipal Hospital from December 2020 to November 2023 were retrospectively analyzed, which included 26 males and 16 females, with a median age of 59 (47, 82) years old. According to the number of courses of treatment with Daratumumab, patients were divided into three groups: long course group (≥9 courses, n=21), medium course group (7-8 courses, n=12), and short course group (≤6 courses, n=9). The deadline for follow-up was November 10, 2023, and the follow-up period was 15.6 (6.0, 34.0) months. After completing at least 2 courses of treatment, patients were evaluated for efficacy, including stringent complete response (sCR), complete response (CR), very good partial response (VGPR), partial response (PR), minimal response (MR), stable disease (SD), and progressive disease (PD). Basic clinical characteristics of patients, overall response rate of treatment, and adverse reactions were statistically analyzed. Kaplan-Meier method was used to compare the differences of progression-free survival (PFS) in patients with different courses of treatment. Results: Among the 42 patients, 15 (35.7%) had extramedullary disease or plasmacytic leukemia, 7 (16.6%) had amyloidosis, and 18 (42.9%) had renal insufficiency. In Mayo stage, 25 patients (59.5%) were at high risk of myeloma cytogenetic stratification, 8 patients (19%) were standard risk, 9 patients (21.4%) had no cytogenetic data. There were 16 patients with second-line treatment (38.0%), 13 patients with third-line treatment (31%), and 13 patients with more than fourth-line treatment (31%). All patients received at least 2 courses of treatment, achieving the best degree of disease response in 4 cases of sCR (9.5%), 3 cases of CR (7.1%), 10 cases of VGPR (23.8%), 11 cases of PR (26.2%), and 6 cases of MR (14.2%). The overall response rate (ORR) was 80.9% (34/42). The overall response rate was 100% (21/21) in the long course group, 91.6% (11/12) in the medium course group and 22.2% (2/9) in the short course group. Kaplan-Meier survival analysis showed that the duration of PFS was 5.0 (95%CI: 3.1-6.9) months in the short course group,>8.0 months in the medium course group, and>38.0 months in the long course group, the difference was statistically significant (P<0.05). Grade≥3 adverse reactions were mainly neutropenia (3 cases) and thrombocytopenia (1 case). None of the patients discontinued treatment due to adverse reactions. Conclusion: Treatment of RRMM with a regimen containing Daratumumab requires a longer course of treatment to achieve maximum efficacy and the adverse reactions can be controlled.

Abstract
Objective: To analyze the efficacy and safety of first-line treatment with an anti-CD38 monoclonal antibody regimen for primary plasma cell leukemia (pPCL). Methods: Patients diagnosed with pPCL from December 1st, 2018 to July 26th, 2023, receiving first-line treatment of anti-CD38 monoclonal antibody-based regimens across multiple centers including Peking University People's Hospital, Fuxing Hospital of Capital Medical University, Qingdao Municipal Hospital, Shengjing Hospital of China Medical University, Handan Central Hospital, the First Affiliated Hospital of Harbin Medical University, the Fourth Hospital of Hebei Medical University and General Hospital of Ningxia Medical University were consecutively included. A total of 24 pPCL patients were included with thirteen being male and eleven being female. The median age [M(Q1, Q3)] was 60 (57, 70) years. Patients were grouped according to peripheral blood plasma cell (PBPC) percentage [5%-19% (n=14) vs ≥20% (n=10)]. Last follow-up date was September 26th, 2023. The median follow-up period was 9.1 (4.2, 15.5) months. Patients' data related with clinical baseline characteristics, efficacy, survival and safety were retrospectively collected. Cox proportional hazards regression model was used to analyze risk factors associated with survival. Results: Among 24 pPCL patients, 16 (66.7%) patients had anemia at diagnosis, 13(54.2%) patients had thrombocytopenia, 8 (33.3%) patients had a baseline estimated glomerular filtration rate (eGFR)<40 ml·min-1·(1.73m2)-1, 13 (54.2%) patients had elevated lactate dehydrogenase (LDH) levels. The median PBPC percentage was 16% (8%, 26%) . Fluorescence in situ hybridization testing indicated that patients harboring 17p deletion, t(4;14) or t(14;16) were 6 (25.0%), 4 (16.7%) and 4 (16.7%), respectively. The overall response rate was 83.3% (20/24). The median progression-free survival (PFS) was 20.5 (95%CI: 15.8-25.2) months, and the median overall survival (OS) was not reached. Estimated 1-year and 2-year PFS and OS rates were 75.0% and 89.1%, 37.5% and 53.4%, respectively. The median PFS and OS for patients with PBPC percentages 5%-19% and≥20% were not reached and 20.5 (95%CI:15.7-25.3) months, 17.8 months and not reached, respectively. There was no significant statistical difference of PFS and OS between two groups (all P>0.05). Multivariate Cox regression analysis showed that 1p32 deletion was the risk factor associated with PFS (HR=7.7, 95%CI: 1.1-54.9, P=0.043). Seventeen patients (70.8%) developed grade 3-4 hematologic toxicities. Twelve patients (50.0%) developed grade 3-4 thrombocytopenia. Sixteen patients (66.7%) developed infection. All hematologic toxicities and infections were improved after supportive treatment. Conclusion: First-line treatment with anti-CD38 monoclonal antibody-based therapy for pPCL is effective and safe.

Abstract
Metabolites are important indicators of cancer and mutations in genes involved in amino acid metabolism may influence tumorigenesis. Immunotherapy is an effective cancer treatment option; however, its relationship with amino acid metabolism has not been reported. In this study, RNA-seq data for 371 liver cancer patients were acquired from TCGA and used as the training set. Data for 231 liver cancer patients were obtained from ICGC and used as the validation set to establish a gene signature for predicting liver cancer overall survival outcomes and immunotherapeutic responses. Four reliable groups based on 132 amino acid metabolism-related DEGs were obtained by consistent clustering of 371 HCC patients and a four-gene signature for prediction of liver cancer survival outcomes was developed. Our data show that in different clinical groups, the overall survival outcomes in the high-risk group were markedly low relative to the low-risk group. Univariate and multivariate analyses revealed that the characteristics of the 4-gene signature were independent prognostic factors for liver cancer. The ROC curve revealed that the risk characteristic is an efficient predictor for 1-, 2-, and 3-year HCC survival outcomes. The GSVA and KEGG pathway analyses revealed that high-risk score tumors were associated with all aspects of the degree of malignancy in liver cancer. There were more mutant genes and greater immune infiltrations in the high-risk groups. Assessment of the three immunotherapeutic cohorts established that low-risk score patients significantly benefited from immunotherapy. Then, we established a prognostic nomogram based on the TCGA cohort. In conclusion, the 4-gene signature is a reliable diagnostic marker and predictor for immunotherapeutic efficacy.

Abstract
Objective: To evaluate the efficacy and safety of bendamustine combined with pomalidomide and dexamethasone (BPD regimen) in the treatment of relapsed multiple myeloma (MM) with extramedullary disease. Methods: This open, single-arm, multicenter prospective cohort study included 30 relapsed MM patients with extramedullary disease diagnosed in seven hospitals including Qingdao Municipal Hospital. The patients were treated with BPD regimen from February 2021 to November 2022. This study analyzed the efficacy and adverse reactions of the BPD regimen. Results: The median age of the 30 patients was 62 (47-72) years, of which 18 (60% ) had first-time recurrence. The overall response rate (ORR) of the 18 patients with first-time recurrence was 100%, of which three (16.7% ) achieved complete remission, 10 (55.5% ) achieved very good partial remission (VGPR), and five (27.8% ) achieved partial remission (PR). The ORR of 12 patients with recurrence after second-line or above treatment was 50%, including zero patients with ≥VGPR and six patients (50% ) with PR. Three cases (25% ) had stable disease, and three cases (25% ) had disease progression. The one-year progression free survival rate of all patients was 65.2% (95% CI 37.2% -83.1% ), and the 1-year overall survival rate was 90.0% (95% CI 76.2% -95.4% ). The common grade 3-4 hematology adverse reactions included two cases (6.7% ) of neutropenia and one case (3.3% ) of thrombocytopenia. The overall adverse reactions are controllable. Conclusions: The BPD regimen has good efficacy and tolerance in relapsed MM patients with extramedullary disease.

Abstract
Objectives: This study aimed to assess the efficacy and safety of bendamustine in combination with rituximab (BR regimen) for the treatment of newly diagnosed indolent B-cell non-Hodgkin's lymphoma (B-iNHL) and elderly mantle cell lymphoma (eMCL) . Methods: From December 1, 2020 to September 10, 2022, a multi-center prospective study was conducted across ten Grade A tertiary hospitals in Shandong Province, China. The BR regimen was administered to evaluate its efficacy and safety in newly diagnosed B-iNHL and eMCL patients, and all completed at least four cycles of induction therapy. Results: The 72 enrolled patients with B-iNHL or MCL were aged 24-74 years, with a median age of 55 years. Eastern Cooperative Oncology Group (ECOG) performance status scores of 0-1 were observed in 76.4% of patients, while 23.6% had scores of 2. Disease distribution included follicular lymphoma (FL) (51.4% ), marginal zone lymphoma (MZL) (33.3% ), eMCL (11.1% ), and the unknown subtype (4.2% ). According to the Ann Arbor staging system, 16.7% and 65.3% of patients were diagnosed with stage Ⅲ and stage Ⅳ lymphomas, respectively. Following four cycles of BR induction therapy, the overall response rate was 98.6%, with a complete response (CR) rate of 83.3% and a partial response (PR) rate of 15.3%. Only one eMCL patient experienced disease progression during treatment, and only one FL patient experienced a relapse. Even when evaluated using CT alone, the CR rate was 63.9%, considering the differences between PET/CT and CT assessments. The median follow-up duration was 11 months (range: 4-22), with a PFS rate of 96.8% and an OS rate of 100.0%. The main hematologic adverse reactions included grade 3-4 leukopenia (27.8%, with febrile neutropenia observed in 8.3% of patients), grade 3-4 lymphopenia (23.6% ), grade 3-4 anemia (5.6% ), and grade 3-4 thrombocytopenia (4.2% ). The main non-hematologic adverse reactions such as fatigue, nausea/vomiting, rash, and infections occurred in less than 20.0% of patients. Conclusion: Within the scope of this clinical trial conducted in China, the BR regimen demonstrated efficacy and safety in treating newly diagnosed B-iNHL and eMCL patients.

Abstract
OBJECTIVE Three cases of rare alleles of HLA-C with zero mismatched PCR-SBT results were analyzed by full-length sequencing to determine the true genotypes. METHODS Three rare HLA-C alleles with zero mismatched PCR-SBT results were screened from clinical transplant matching samples, and the full-length sequence was detected by next-generation sequencing technology. RESULTS The results of PCR-SBT typing of 3 samples were: HLA-C*03:04, 12:167; HLA-C*07:291, 15:02; HLA-C*01:43, 08:16. Other alleles were not in the CWD table of common and confirmed HLA alleles in China (version 2.3) except common allele HLA-C*03:04, HLA-C*15:02. NGS full-length sequencing revealed that the HLA-C genotypes of the three samples were a combination of common alleles and novel alleles, and the three novel alleles had a base mutation in exons 6, 2, and 4, respectively. The novel allele sequences have been submitted to the Genbank database (MK629722, MK335474, MK641803), which were officially named HLA-C*03:04:74, HLA-C*15:192, HLA-C*08:01:25 by the WHO HLA Nomenclature Committee. The HLA high-resolution typing results of 3 samples were: HLA-C*03:04:74, HLA-C*12:03; HLA-C*07:02, HLA-C*15:192; HLA-C*01:02, HLA-C*08:01:25. CONCLUSION HLA typing results containing rare alleles should be treated cautiously, and the full-length sequence should be verified by NGS or cloning. The laboratory finally confirmed that the 3 cases of PCR-SBT zero mismatch HLA-C genotypes are the combination of common alleles and novel alleles by NGS sequencing, which provides an accurate basis for clinical transplantation matching and enriches the human HLA genetic database.

Abstract
Effective quantum communication between remote quantum nodes requires high fidelity quantum state transfer and remote entanglement generation. Recent experiments have demonstrated that microwave photons, as well as phonons, can be used to couple superconducting qubits, with a fidelity limited primarily by loss in the communication channel [P. Kurpiers et al., Nature (London) 558, 264 (2018)NATUAS0028-083610.1038/s41586-018-0195-y; C. J. Axline et al., Nat. Phys. 14, 705 (2018)NPAHAX1745-247310.1038/s41567-018-0115-y; P. Campagne-Ibarcq et al., Phys. Rev. Lett. 120, 200501 (2018)PRLTAO0031-900710.1103/PhysRevLett.120.200501; N. Leung et al., npj Quantum Inf. 5, 18 (2019)2056-638710.1038/s41534-019-0128-0; Y. P. Zhong et al., Nat. Phys. 15, 741 (2019)NPAHAX1745-247310.1038/s41567-019-0507-7; A. Bienfait et al., Science 364, 368 (2019)SCIEAS0036-807510.1126/science.aaw8415]. Adiabatic protocols can overcome channel loss by transferring quantum states without populating the lossy communication channel. Here, we present a unique superconducting quantum communication system, comprising two superconducting qubits connected by a 0.73 m-long communication channel. Significantly, we can introduce large tunable loss to the channel, allowing exploration of different entanglement protocols in the presence of dissipation. When set for minimum loss in the channel, we demonstrate an adiabatic quantum state transfer protocol that achieves 99% transfer efficiency as well as the deterministic generation of entangled Bell states with a fidelity of 96%, all without populating the intervening communication channel, and competitive with a qubit-resonant mode-qubit relay method. We also explore the performance of the adiabatic protocol in the presence of significant channel loss, and show that the adiabatic protocol protects against loss in the channel, achieving higher state transfer and entanglement fidelities than the relay method.

Abstract
The prognostic and therapeutic value of the tumor microenvironment (TME) in various cancer types is of major interest. Characterization of the TME often relies on a small representative tissue sample. However, the adequacy of such a sample for assessing components of the TME is not yet known. Here, we used immunohistochemical (IHC) staining and 7-color multiplex staining to evaluate CD8 (cluster of differentiation 8), CD68, PD-L1 (programmed death-ligand 1), CD34, FAP (fibroblast activation protein), and cytokeratin in 220 tissue cores from 26 high-grade serous ovarian cancer samples. Comparisons were drawn between a larger tumor specimen and smaller core biopsies based on number and location (central tumor vs. peripheral tumor) of biopsies. Our analysis found that the correlation between marker-specific cell subsets in larger tumor versus smaller core was stronger with two core biopsies and was not further strengthened with additional biopsies. Moreover, this correlation was consistently strong regardless of whether the biopsy was taken at the center or at the periphery of the original tumor sample. These findings could have a substantial impact on longitudinal assessment for detection of biomarkers in clinical trials.

Abstract
Phonons, and in particular surface acoustic wave phonons, have been proposed as a means to coherently couple distant solid-state quantum systems. Individual phonons in a resonant structure can be controlled and detected by superconducting qubits, enabling the coherent generation and measurement of complex stationary phonon states. We report the deterministic emission and capture of itinerant surface acoustic wave phonons, enabling the quantum entanglement of two superconducting qubits. Using a 2-millimeter-long acoustic quantum communication channel, equivalent to a 500-nanosecond delay line, we demonstrate the emission and recapture of a phonon by one superconducting qubit, quantum state transfer between two superconducting qubits with a 67% efficiency, and, by partial transfer of a phonon, generation of an entangled Bell pair with a fidelity of 84%.

Abstract
Both CD5 and CD43 are expressed on the surface of B lymphocytes of definite phase and associated with the adverse outcome in diffuse large B-cell lymphoma (DLBCL). However, the relationship between CD5 and CD43 expression and the prognostic value of CD5/CD43 coexpression in DLBCL are unknown. We herein determined the correlation between CD5 and CD43 expression, as separate factors or in combination, with the clinicopathological features and survival of 200 patients with DLBCL receiving standard chemotherapy with or without rituximab. Among these DLBCL patients, CD5 expression, CD43 expression, and CD5/CD43 coexpression were detected in 18 (9%), 57 (27%), and 10 (5%) patients, respectively, and all were positively correlated with advanced age and nongerminal cell type. CD5-positive and CD43-positive DLBCL patients had poorer event-free survival (EFS, P < 0.001) and overall survival (OS, P < 0.001) than CD5-negative and CD43-negative patients, respectively. CD5/CD43 coexpression was correlated with a significantly worse prognosis than CD5 or CD43 expression alone. Univariate analysis showed that CD5 expression, CD43 expression, and CD5/CD43 coexpression were all adverse prognostic factors for DLBCL patient survival, and CD5/CD43 coexpression was associated with a greater relative risk for recurrence and death than either CD5 or CD43 expression alone. Multivariate analysis demonstrated that CD5/CD43 coexpression was an independent prognostic factor for EFS (P < 0.001) and OS (P < 0.001) in DLBCL. In conclusion, our data indicate that DLBCL patients with CD5/CD43 coexpression represent a specific subgroup with a significantly worse prognosis than those expressing either marker alone.

Abstract
Objective: To evaluate the efficacy and safety of lenalidomide in a real-world clinical practice in Chinese patients with multiple myeloma (MM). Methods: It was a prospective, multi-center, observational study. A total of 165 consecutive patients with MM treated with lenalidomide-based regimens were enrolled in 12 hospitals from June 2013 to November 2015. Relevant information was recorded, such as baseline clinical data, cytogenetic abnormalities, treatment regimens, and duration of treatment, safety, and survival. Results: (1)There were 126 relapsed and refractory MM (RRMM) patients, 25 newly diagnosed patients and 19 maintenance patients. The evaluable RRMM patients accounted for 120 cases, among which 74 cases(61.7%) reached the partial response (PR) or above, and a very good partial response (VGPR) in 16 patients (13.3%), a complete response (CR) in 14 cases (11.7%), a strictly complete response (sCR) in 4 cases (3.3%). Thus, a VGPR or above in 34 patients accounted for 28.3%. (2)The median follow-up was 13 months, the median time to progression 12 months. The median survival after receiving lenalidomide was 19 months, and the median overall survival (OS) was 62 months. (3) The univariate analysis in 120 RRMM patients suggested that prognostic factors for significant improvement in PFS included normal karyotype, international staging system (ISS) Ⅰ-Ⅱ, t(4; 14) negative (detected by fluorescence in situ hybridization), non-bortezomib resistance and response to previous regimens. As to OS, non-bortezomib resistance, response to previous regimens and non-primary refractoriness were positive factors. Multivariate analysis showed that the response to previous regimens (PR or better) was an independent good prognostic factor for progress-free survival(PFS), non-bortezomib resistance and non-primary refractoriness for OS. (4) Grade 3 or 4 adverse events that occurred in more than 10% of all enrolled patients were neutropenia (12.7%), leukocytosis(11.5%) and thrombocytopenia (12.7%). Owing to intolerance of toxic side effects, 7 cases withdrew lenalidomide. Conclusions: No matter what combination, regimens containing lenalidomide are effective to RRMM patients with overall response rate 61.7%, a time to progression 12 months and an overall survival 62 months.The toxicity is quite tolerable and manageable. In addition, the response to previous treatment (reached PR or above) is the independent good prognostic factor for PFS, non-bortezomib resistance and non-primary refractoriness for OS. Clinical trail registration: Clinicaltrials.gov, NCT01947309.

Abstract
Anyons are exotic quasiparticles obeying fractional statistics, whose behavior can be emulated in artificially designed spin systems. Here we present an experimental emulation of creating anyonic excitations in a superconducting circuit that consists of four qubits, achieved by dynamically generating the ground and excited states of the toric code model, i.e., four-qubit Greenberger-Horne-Zeilinger states. The anyonic braiding is implemented via single-qubit rotations: a phase shift of π related to braiding, the hallmark of Abelian 1/2 anyons, has been observed through a Ramsey-type interference measurement.

Abstract
Germ cell tumors account for 98% of all testicular malignancies. Delays in seeking treatment are unfortunately common and may lead to metastatic spread. The present study reported a case of a 24-year-old man with a giant 12×10 cm left inguinal mass and a left neck mass that had grown rapidly during recent months. Computed tomography confirmed that the mass measured 12.1×9.4 cm and was a left undescended testicle malignancy, and also revealed widespread metastasis to the liver and a large retroperitoneal mass (12.6×8.2 cm). Immunohistochemical staining confirmed seminoma. The patient was treated with chemotherapy with the VIP protocol (cisplatin, etoposide and ifosfamide). Following courses of chemotherapy, the patient received complete clinical remission and was disease-free at the 6 month follow-up.

Here we report on the realization of the process in the superconducting Xmon and phase qutrits—two ladder-type three-level systems in which the ground state population is coherently transferred to the second excited state via the dark state subspace. We demonstrate that the population transfer efficiency is no less than 96% and 67% for the two devices, which agree well with the numerical simulation of the master equation. Population transfer via stimulated Raman adiabatic passage is significantly more robust against variations of the experimental parameters compared with that via the conventional resonant π pulse method. Our work opens up a new venue for exploring the process for quantum information processing using the superconducting artificial atoms. Quantum state engineering necessitates transfer between quantum states. Here the authors demonstrate coherent population transfer between un- or weakly-coupled states of solid state systems, superconducting Xmon and phase qutrits, using stimulated Raman adiabatic passage and microwave driving.

Abstract
Substantial evidence implicates that low-abundance cancer stem cells (CSCs) are responsible for tumor metastasis and recurrence in hepatocellular carcinoma (HCC). Side population (SP) cells possess typical CSCs-like features, and are frequently considered as a special subpopulation in which CSCs are enriched and in studies may be considered as a substitute for CSCs. The aim of the present study was to examine the abundance of SP cells in human HCC cell lines with different metastatic potentials and compare their CSC-like, tumorigenic and invasive properties with those of the main population (MP) cells. An experimental system is described for identifying SP cells and analyzing their CSC-like properties. The relative abundance of SP cells correlated directly with the metastatic potential of the HCC cell line: HCCLM3, 16.3±2.2%; MHCC97-H, 8.4±0.7%; MHCC97-L, 4.7±0.5%; and Huh7, 1.0±0.3% (P<0.05). SP cells isolated from HCCLM3 cultures showed significantly higher proliferation rates and clonogenicity than the corresponding MP cells, in addition to higher migration and invasive abilities in vitro and greater tumorigenicity in mice. Expression levels of all CSC-associated genes tested, except EpCAM and Oct4, were significantly higher in SP cells. The findings revealed that the proportion of SP cells correlates with metastatic potential, and SP cells demonstrated the characteristics expected of CSCs, implicating them in HCC metastasis. Further studies on the identification and characterization of SP cells using clinical HCC specimens will contribute to the understanding of how SP cells are involved in these disease processes.

Abstract
We suggest and demonstrate a protocol which suppresses the low-frequency dephasing by qubit motion, i.e., transfer of the logical qubit of information in a system of n≥2 physical qubits. The protocol requires only the nearest-neighbor coupling and is applicable to different qubit structures. Our analysis of its effectiveness against noises with arbitrary correlations, together with experiments using up to three superconducting qubits, shows that for the realistic uncorrelated noises, qubit motion increases the dephasing time of the logical qubit as √n. In general, the protocol provides a diagnostic tool for measurements of the noise correlations.

Abstract
Cancer stem cells (CSCs) are thought to be responsible for tumor relapse and metastasis due to their abilities to self-renew, differentiate, and give rise to new tumors. Cyclooxygenase-2 (COX-2) is highly expressed in several kinds of CSCs, and it helps promote stem cell renewal, proliferation, and radioresistance. Whether and how COX-2 contributes to CSC migration and invasion is unclear. In this study, COX-2 was overexpressed in the CSC-like side population (SP) of the human hepatocellular carcinoma (HCC) cell line HCCLM3. COX-2 overexpression significantly enhanced migration and invasion of SP cells, while reducing expression of metastasis-related proteins PDCD4 and PTEN. Treating SP cells with the selective COX-2 inhibitor celecoxib down-regulated COX-2 and caused a dose-dependent reduction in cell migration and invasion, which was associated with up-regulation of PDCD4 and PTEN. These results suggest that COX-2 exerts pro-metastatic effects on SP cells, and that these effects are mediated at least partly through regulation of PDCD4 and PTEN expression. These results further suggest that celecoxib may be a promising anti-metastatic agent to reduce migration and invasion by hepatic CSCs.

Abstract
Quantum phase transitions play an important role in many-body systems and have been a research focus in conventional condensed-matter physics over the past few decades. Artificial atoms, such as superconducting qubits that can be individually manipulated, provide a new paradigm of realising and exploring quantum phase transitions by engineering an on-chip quantum simulator. Here we demonstrate experimentally the quantum critical behaviour in a highly controllable superconducting circuit, consisting of four qubits coupled to a common resonator mode. By off-resonantly driving the system to renormalize the critical spin-field coupling strength, we have observed a four-qubit nonequilibrium quantum phase transition in a dynamical manner; that is, we sweep the critical coupling strength over time and monitor the four-qubit scaled moments for a signature of a structural change of the system's eigenstates. Our observation of the nonequilibrium quantum phase transition, which is in good agreement with the driven Tavis–Cummings theory under decoherence, offers new experimental approaches towards exploring quantum phase transition-related science, such as scaling behaviours, parity breaking and long-range quantum correlations. Quantum phase transitions are a discontinuous change in a property of the ground state or the structure of the excited states as a system parameter traverses a critical point. Here, the authors recreate analogous effects with laboratory-achievable light-matter coupling in an on-chip superconducting circuit

Abstract
Soybean aphid (SA: Aphis glycines Matsumura) is one of the most serious pests of soybean [Glycine max (L.) Merr.] worldwide. A single dominant gene was found to control SA resistance in soybean line P746, which exhibits antibiosis resistance. This study aimed to define the location of the SA resistance gene in P746. A F2:3 mapping population, including 312 individuals, was created based on the cross of P746 and 'Dongnong 47'. Combined with bulked segregant analysis, all of the 1015 simple sequence repeats (SSR) from the soybean consensus map were used to locate the tentative genomic region of the SA resistance gene in P746. The effort resulted in the mapping of R_P746, the SA resistance gene in P746, and was flanked on either side by Satt334 and Satt335 on chromosome 13. By chromosome walking with SSRs from BARCSOYSSR_1.0, R_P746 was mapped between BARCSOYSSR_13_1278 and BARCSOYSSR_13_1363, with distances of 4.2 and 2.6 cM, respectively. The results indicate that R_P746 might be different to the SA resistance genes previously reported. The markers that are closely linked to R_P746 are expected to be useful for marker assisted selection in future soybean aphid resistance breeding programs.

Abstract
Experiments were conducted on the inerting of magnesium dust with N(2), CO(2), and Ar. Comparing the maximum explosion pressure, maximum rate of pressure rise, and limiting oxygen concentration with different inertants, it was determined that Ar is not the best inert gas under all conditions as commonly believed. N(2) was more effective than Ar as an inertant. CO(2) provided more inerting effect than either Ar and N(2) in low magnesium dust concentrations, although explosibility was increased at higher dust concentrations. Both N(2) and CO(2) as inerting agents showed higher LOC values than Ar. These results indicated that N(2) is a more economical inerting gas than Ar for the tested coarse magnesium dust.

Abstract
The objective of the present research is to study the potential of using Fourier transform near-infrared spectroscopy (FT-NIR) in conjunction with discriminant partial least squares (DPLS) chemometric techniques for the discrimination of honey authenticity. First, seventy one commercial honey samples from Chinese market were analyzed to detect the levels of honey adulteration by stable carbon isotope ratio and the chemical result showed that the samples include unadulterated (n = 27) and adulterated (n = 44) products. The samples were scanned in the spectral region between 4 000 and 11 000 cm(-1) by FT-NIR spectrometer with an optic fiber of 2 mm path-length and an InGaAs detector and then divided randomly five times into two sets, namely calibration sets and validation sets, respectively. Five kinds of mathematic models of honey samples were established for classification of honeys as authentic or adulterated by using DPLS. Different spectra pretreatment methods, spectral range and different principal component factors were selected to optimize the calibration models. The calibration models were successfully validated with exterior cross-validation methods. Through comparison analysis of the results, the overall corrected identification rate of authentic and adulterated honey samples in five calibration models were 91.49%, 94.68%, 92.98%, 93.86% and 94.87%, respectively. The correct classification rate of the validation samples was 93.75%, 89.58%, 89.29%, 92.31% and 86.96% from model one to model five, respectively and 100% of adulterated honey samples were correctly identified and classified in validation models 2, 3 and 4. The results demonstrated that FT-NIR together with DPLS could be used as a rapid and cost-efficient screening tool for discrimination of commercial honey adulteration, and the analytical technique would be significant to Chinese honey quality supervision.

Abstract
BACKGROUND & OBJECTIVE C-erbB2, C-erbB3, and C-erbB4 are numbers of epidermal growth factor family. It has been confirmed that C-erbB2 was related to ovarian carcinoma, but the relationship of C-erbB3 and C-erbB4 with ovarian carcinoma is unclear. The objective of this study was to explore the relationship of expression of C-erbB2, C-erbB3, and C-erbB4 with ovarian carcinoma. METHODS Streptavidin-peroxidase immunohistochemistry method was used to determine the expression of C-erbB2, C-erbB3, and C-erbB4 in 49 cases of ovarian malignant neoplasms, 21 cases of ovarian benign neoplasms, and 19 cases of normal ovarian tissues (control), then the relationship of expression of C-erbB2, C-erbB3, C-erbB4 and clinicopathologic parameters in ovarian neoplasm was analyzed. RESULTS (1) The positive expression rates of C-erbB2, C-erbB3, and C-erbB4 in ovarian malignant neoplasms were 75.51%, 69.39%, and 65.31%, respectively, and they were higher than that in ovarian benign neoplasms (19.05%, 23.81%, and 23.81%, respectively) and control (21.05%, 15.79%, and 21.05%, respectively)(P< 0.05). (2) There was not significant difference between the expression of C-erbB2, C-erbB3, and C-erbB4 in ovarian malignant neoplasms and its pathologic type and grade (P >0.05). (3) The positive expression rates of C-erbB2, C-erbB3, and C-erbB4 in the patients with late stage or large amount of ascetic volume ( >500 ml) were 90.0% and 91.3%, respectively, and those also were higher than that in early stage or ascetic volume< 500 ml (P< 0.05). (4) The cumulative survival time of the patients with positive expression of C-erbB2 or C-erbB4 was longer than that without expression (P< 0.01). The analysis of Cox model showed that expressions of C-erbB2 and C-erbB4 in ovarian malignant were also independent prognosis factors for ovarian cancer. CONCLUSION The C-erbB family would play an importation role in ovarian malignant neoplasms, and also was related to poor prognosis in ovarian cancer.

Abstract
This study investigated the expression patterns of estrogen receptor-alpha (ER alpha) and -beta (ER beta) in the cultured hippocampal cells of neonatal rats by combined application of cell culture and immunocytochemistry. The results revealed that the expression difference between ER alpha and ER beta seemed to be not obvious in the cultured hippocampal cells of neonatal rats. Moreover, immunoreactivity for either ER alpha or ER beta was observed to be localized in the majority of not only neurons but also astrocytes. The coexpression of both ER alpha and ER beta in the same individual cell was also demonstrated by the double-label immunocytochemistry. Western blot analysis showed that immunoreactivity for ER alpha in the neonatal hippocampal tissues was much higher than in the adult (became rather weak), although there was not such a great difference of immunoreactivity for ER beta. The data also provide direct evidence for the expression of ER subtypes within GABAergic neurons in hippocampal cell cultures and suggest that estrogen's effect on the hippocampus may be mediated at least in part by its ER-containing GABAergic neurons.
