Dialogues on the theory and practice of literary translation
\"The book is a collection of the dialogues between Xu Jun, a well-known expert in French literary translation and eminent \"Changjiang\" scholar in translation studies in China, and some celebrated literary translators in contemporary China, some of whom are also literary scholars, linguists, poets, prosers, and editors. It's a fundamental achievement of research on the literary translation in the 20th century in China, involving multiple literary types, such as novels, poetry, dramas, prose, and fairy tales, and multiple languages, such as English, French, German, Russian, Italian, Spanish, Japanese, and Sanskrit. The dialogues are centered around the fundamental issues in the theory and practice of literary translation, such as the re-creation in literary translation, the relationship between form and content in literary translation, the subjectivity of literary translators, the literary translation standards and principles, the gains and losses in literary translation, the principles and methods of literary criticism, and so on. Those translation experts' experience and multiple strategies not only play an active role in guiding literary translator in practice but also is beneficial to the theoretical development in literary translation. Therefore, the book will contribute to worldwide translation studies and get well recognized by translation studies students, teachers, and scholars in the world\"-- Provided by publisher.

Furthermore, we also examine the heavy quark symmetry breaking effect in the hidden-charm and hidden-bottom systems by taking into account the mass splittings in the propagators of the intermediate states.

Brain functional changes across mood states in bipolar disorder: from a large-scale network perspective
2024
Exploring the neural basis related to different mood states is a critical issue for understanding the pathophysiology underlying mood switching in bipolar disorder (BD), but research has been scarce and inconsistent.
Resting-state functional magnetic resonance imaging data were acquired from 162 patients with BD: 33 (hypo)manic, 64 euthymic, and 65 depressive, and 80 healthy controls (HCs). The differences of large-scale brain network functional connectivity (FC) between the four groups were compared and correlated with clinical characteristics. To validate the generalizability of our findings, we recruited a small longitudinal independent sample of BD patients (n = 11). In addition, we examined topological nodal properties across four groups as exploratory analysis.
A specific strengthened pattern of network FC, predominantly involving the default mode network (DMN), was observed in (hypo)manic patients when compared with HCs and bipolar patients in other mood states. Longitudinal observation revealed an increase in several network FCs in patients during (hypo)manic episode. Both samples evidenced an increase in the FC between the DMN and ventral attention network, and between the DMN and limbic network (LN) related to (hypo)mania. The altered network connections were correlated with mania severity and positive affect. Bipolar depressive patients exhibited decreased FC within the LN compared with HCs. The exploratory analysis also revealed an increase in degree in (hypo)manic patients.
Our findings identify a distributed pattern of large-scale network disturbances in the unique context of (hypo)mania and thus provide new evidence for our understanding of the neural mechanism of BD.

Negative association of C-reactive protein-albumin-lymphocyte index (CALLY index) with all-cause and cause-specific mortality in patients with cancer: results from NHANES 1999–2018
2024
Background
The CALLY index, which is derived from C-reactive protein (CRP) content, serum albumin level, and total lymphocyte count, reflects the immune, nutritional, and inflammatory status of the body. Lack of sufficient evidence on the correlation between the CALLY index and the prognosis of cancer patients with various cancer forms. This study seeks to elucidate the association between the CALLY index and mortality from all causes as well as specific causes in cancer patients within a U.S. population.
Methods
This investigation encompassed 3511 cancer-afflicted adults from the National Health and Nutritional Examination Surveys (NHANES) spanning 1999 to 2018. The CALLY index was measured at baseline only. The relationship between the CALLY index and mortality from both all causes and cancer specifically was examined using Cox proportional hazards models. Additionally, restricted cubic spline, piecewise linear regression, and various subgroup and sensitivity analyses were employed.
Results
Over a median follow-up of 103 months, 1,355 deaths occurred, and the incidence of all-cause mortality for these participants was 38.34%. Our findings indicate that an elevated CALLY index correlates with a diminished risk of all-cause mortality. Upon applying a natural logarithmic transformation to the CALLY index, the comprehensively adjusted model revealed that each one-unit increment in ln CALLY corresponded to a 18% decrease in all-cause mortality risk among cancer patients (HR = 0.82, 95% CI:0.79–0.86). Analyses of mortality due to cardiac and cancer-related causes yielded consistent results, which were robust across various subgroup and sensitivity analyses.
Conclusion
The CALLY index demonstrated a linear and negative association with all-cause mortality, as well as mortality caused by cancer and cardiac conditions, highlighting its significant prognostic value in patients with oncological conditions.

How to understand the X(2900)?
2022
In this work, the S- and P-wave D¯∗K∗ interactions are studied in a coupled-channel formalism to understand the recently observed X0(2900) and X1(2900) at LHCb. The experimental event distributions can be well described, and two states with I(JP)=0(0+) and 0(1-) are yielded in a unified framework. The masses of the 0+ and 1- states are consistent with the experimental data, but the width of the 0+ state is larger than that of the 1- one. The X1(2900) can be interpreted as the P-wave excitation of the ground-state X0(2900) in the hadronic molecular picture. The S- and P-wave multiplets in the D¯∗K∗ system have many members, so the present peak in the D-K+ invariant mass distributions might contain multi substructures.

Systematics of the heavy flavor hadronic molecules
2022
With a quark level interaction, we give a unified description of the loosely bound molecular systems composed of the heavy flavor hadrons (D¯,D¯∗), (Λc,Σc,Σc∗), and (Ξc,Ξc′,Ξc∗). Using the Pc states as inputs to fix the interaction strength of light quark-quark pairs, we reproduce the observed Pcs and Tcc+ states and predict another narrow Tcc′+ state with quantum numbers [D∗D∗]J=1I=0. If we require a satisfactory description of the Tcc+ and Pc states simultaneously, our framework prefers the assignments of the Pc(4440) and Pc(4457) as the [ΣcD¯∗]J=1/2I=1/2 and [ΣcD¯∗]J=3/2I=1/2 states, respectively. We propose the isospin criterion to explain naturally why the experimentally observed Tcc, Pc, and Pcs molecular candidates prefer the lowest isospin numbers. We also predict the loosely bound states for the bottom di-hadrons.

RNA sequencing reveals the expression profiles of circRNA and indicates that circDDX17 acts as a tumor suppressor in colorectal cancer
2018
Background
Circular RNA (circRNA) is a novel class of noncoding RNAs with functions in various pathophysiological activities. However, the expression profiles and functions of circRNAs in colorectal cancer (CRC) remain largely unknown.
Methods
High-throughput RNA sequencing (RNA-seq) was performed to assess circRNA expression profiles in 4 paired CRC tissues, and significantly dysregulated circRNAs were validated by quantitative real-time polymerase chain reaction (qRT-PCR). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed to predict the potential functions of dysregulated circRNAs. Target miRNAs of circRNAs were predicted using miRanda software, and were further analyzed combining DIANA-miRPath v.3 platform (Reverse Search module) with KEGG pathways of COLORECTAL CANCER and MicroRNAs in cancer (Entry: map05210 and map05206). CircRNA-miRNA interaction networks were constructed using Cytoscape software. Expression levels of a significantly down-regulated circRNA, circDDX17 (hsa_circ_0002211), was detected by qRT-PCR in 60 paired CRC tissues. CircDDX17 was knockdown by siRNA, and the biological functions of circDDX17 were examined in CRC cell lines.
Results
Totally 448 differentially expressed circRNAs were identified, including 394 up-regulated and 54 down-regulated circRNAs. qRT-PCR validation confirmed the reliability of the RNA-Seq data. GO and KEGG analyses revealed that these dysregulated circRNAs were potentially implicated in CRC pathogenesis. Analyses by combining miRanda and miRPath softwares with KEGG pathways suggested that the miRNAs targeted by the top 10 dysregulated circRNAs were associated with the KEGG pathways of COLORECTAL CANCER and MicroRNAs in cancer, indicating that circRNA-miRNA interactions might play important functional roles in the initiation and progression of CRC. The results of qRT-PCR for circDDX17 in 60 paired CRC tissues showed that circDDX17 was significantly down-regulated in CRC tissues and associated with unfavorable clinicopathological parameters. In vitro experiments showed that silencing of circDDX17 promoted CRC cell proliferation, migration, invasion, and inhibited apoptosis.
Conclusions
In conclusion, we have identified numerous circRNAs that are dysregulated in CRC tissues compared with adjacent normal mucosa tissues. Bioinformatic analyses suggested that these dysregulated circRNAs might play important functional roles in CRC tumorigenesis. CircDDX17 functions as a tumor suppressor and could serve as a potential biomarker and a therapeutic target for CRC.

Rational design hybrid nanostructure photocatalysts with efficient charge separation and transfer, and good solar light harvesting ability have critical significance for achieving high solar‐to‐chemical conversion efficiency. Here a highly active and stable composite photocatalyst is reported by integrating ultrathin ZnIn2S4 nanosheets on surface of hollow CdS cube to form the cube‐in‐cube structure. Experimental results combined with density functional theory calculations confirm that the Z‐scheme ZnIn2S4/CdS heterojunction is formed, which highly boosts the charge separation and transfer under the local‐electric‐field at semiconductor/semiconductor interface, and thus prolongs their lifetimes. Moreover, such a structure affords the highly enhanced light‐harvesting property. The optimized ZnIn2S4/CdS nanohybrids exhibit superior H2 generation rate under visible‐light irradiation (λ ≥ 420 nm) with excellent photochemical stability during 20 h continuous operation. The stable composite photocatalyst integrated by ultrathin ZnIn2S4 nanosheets on surface of hollow CdS exhibits outstanding visible‐light‐driven photocatalytic H2 generation activity, due to that: i) the Z‐scheme charge transfer route facilitates charge separation, prolongs carrier lifetimes, and remains strong electron reduction capacity; ii) the unique cube‐in‐cube structure brings abundant active sites, improves light harvesting ability, shortens charge transfer distance.
