Abstract
Objective Despite cardiotoxicity overlap, the trastuzumab/pertuzumab and anthracycline combination remains crucial due to significant benefits. Pegylated liposomal doxorubicin (PLD), a less cardiotoxic anthracycline, was evaluated for efficacy and cardiac safety when combined with cyclophosphamide and followed by taxanes with trastuzumab/pertuzumab in human epidermal growth factor receptor-2 (HER2)-positive early breast cancer (BC). Methods In this multicenter, phase II study, patients with confirmed HER2-positive early BC received four cycles of PLD (30-35 mg/m2) and cyclophosphamide (600 mg/m2), followed by four cycles of taxanes (docetaxel, 90-100 mg/m2 or nab-paclitaxel, 260 mg/m2), concomitant with eight cycles of trastuzumab (8 mg/kg loading dose, then 6 mg/kg) and pertuzumab (840 mg loading dose, then 420 mg) every 3 weeks. The primary endpoint was total pathological complete response (tpCR, ypT0/is ypN0). Secondary endpoints included breast pCR (bpCR), objective response rate (ORR), disease control rate, rate of breast-conserving surgery (BCS), and safety (with a focus on cardiotoxicity). Results Between May 27, 2020 and May 11, 2022, 78 patients were treated with surgery, 42 (53.8%) of whom had BCS. After neoadjuvant therapy, 47 [60.3%, 95% confidence interval (95% CI), 48.5%-71.2%] patients achieved tpCR, and 49 (62.8%) achieved bpCR. ORRs were 76.9% (95% CI, 66.0%-85.7%) and 93.6% (95% CI, 85.7%-97.9%) after 4-cycle and 8-cycle neoadjuvant therapy, respectively. Nine (11.5%) patients experienced asymptomatic left ventricular ejection fraction (LVEF) reductions of ≥10% from baseline, all with a minimum value of >55%. No treatment-related abnormal cardiac function changes were observed in mean N-terminal pro-BNP (NT-proBNP), troponin I, or high-sensitivity troponin. Conclusions This dual HER2-blockade with sequential polychemotherapy showed promising activity with rapid tumor regression in HER2-positive BC. Importantly, this regimen showed an acceptable safety profile, especially a low risk of cardiac events, suggesting it as an attractive treatment approach with a favorable risk-benefit balance.

Abstract
BACKGROUND As a newly identified subtype of HER2-negative tumors associated with a less favorable prognosis, it remains crucial to evaluate potential prognostic and predictive factors, particularly non-invasive biomarkers, for individuals with human epidermal growth factor 2 (HER2) low early-stage breast cancer (EBC). Multiple investigations have highlighted that HER2-negative patients with EBC exhibiting high homologous recombination deficiency (HRD) scores display lower rates of pathological complete response (PCR) to neoadjuvant chemotherapy (NAC). Nevertheless, no study to date has explored the correlation between HRD and the long-term prognosis in HER2-low patients with EBC. PATIENTS AND METHODS This retrospective observational study focuses on primary EBC sourced from The Cancer Genome Atlas dataset (TCGA). It reveals the gene mutation landscape in EBC with low HER2 expression and elucidates the tumor immune landscape across different HRD states. Utilizing bioinformatics analysis and Cox proportional models, along with the Kaplan-Meier method, the study assesses the correlation between HRD status and disease-specific survival (DSS), disease-free interval (DFI), and progression-free interval (PFI). Subgroup analyses were conducted to identify potential variations in the association between HRD and prognosis. RESULTS In the patients with HER2-low breast cancer, patients with homologous recombination related genes (HRRGs) defects had an HRD score about twice that of those without related genes mutations, and were at higher risk of acquiring ARID1A, ATM, and BRCA2 mutations. We also found that most immune cell abundances were significantly higher in EBC tumors with high HRD than in EBC tumors with low HRD or HRD-medium, particularly plasma B-cell abundance, CD8 T-cell abundance, and M1 macrophages. In addition, these tumors with HRD-high also appear to have significantly higher tumor immune scores and lower interstitial scores. Then, we analyzed the relationship between different HRD status and prognosis. There was statistical significance (P = .036 and P = .046, respectively) in DSS and PFI between the HRD-low and HRD-high groups, and patients with HRD-high EBC showed relatively poor survival outcomes. A medium HRD score (hazard ratio, HR = 2.15, 95% CI: 1.04-4.41, P = .038) was a significant risk factor for PFI. Hormone receptor positivity is an important factor in obtaining medium-high HRD score and poor prognosis. CONCLUSION Higher HRD scores were associated with poorer PFI outcomes, particularly in people with HR+/HER2-low. Varied HRD states exhibited distinctions in HRRGs and the tumor immune landscape. These insights have the potential to assist clinicians in promptly identifying high-risk groups and tailoring personalized treatments for patients with HER2-low EBC, aiming to enhance long-term outcomes.

Abstract
BACKGROUND The association between different phenotypes and genotypes of circulating tumor cells (CTCs) and efficacy of neoadjuvant chemotherapy (NAC) remains uncertain. This study was conducted to evaluate the relationship of FTH1 gene-associated CTCs (F-CTC) with/without epithelial-mesenchymal transition (EMT) markers, or their dynamic changes with the efficacy of NAC in patients with non-metastatic breast cancer. PATIENTS AND METHODS This study enrolled 120 patients with non-metastatic breast cancer who planned to undergo NAC. The FTH1 gene and EMT markers in CTCs were detected before NAC (T0), after 2 cycles of chemotherapy (T1), and before surgery (T2). The associations of these different types of CTCs with rates of pathological complete response (pCR) and breast-conserving surgery (BCS) were evaluated using the binary logistic regression analysis. RESULTS F-CTC in peripheral blood ≥1 at T0 was an independent factor for pCR rate in patients with HER2-positive (odds ratio [OR]=0.08, 95% confidence interval [CI], 0.01-0.98, P = .048). The reduction in the number of F-CTC at T2 was an independent factor for BCS rate (OR = 4.54, 95% CI, 1.14-18.08, P = .03). CONCLUSIONS The number of F-CTC prior to NAC was related to poor response to NAC. Monitoring of F-CTC may help clinicians formulate personalized NAC regimens and implement BCS for patients with non-metastatic breast cancer.

Abstract
Wireless power transfer (WPT) technology based on magnetic resonance (a basic physical phenomenon) can directly transfer energy from the source to the load without wires and other physical contacts, and has been successfully applied to implantable medical devices, electric vehicles, robotic arms and other fields. However, due to the frequency splitting of near-field coupling, the resonant WPT system has some unique limitations, such as poor transmission stability and low efficiency. Here, we propose anti-resonance with level pinning for high-performance WPT. By introducing the anti-resonance mode into the basic WPT platform, we uncover the competition between dissipative coupling and coherent coupling to achieve novel level pinning, and construct an effective anti-parity-time (anti-PT)-symmetric non-Hermitian system that is superior to previous PT-symmetric WPT schemes. On the one hand, the eigenvalue of the anti-PT-symmetric system at resonance frequency is always pure real in both strong and weak coupling regions, and can be used to overcome the transmission efficiency decrease caused by weak coupling, as brought about by, for example, a large size ratio of the transmitter to receiver, or a long transmission distance. On the other hand, due to the level pinning effect of the two kinds of coupling mechanisms, the working frequency of the system is guaranteed to be locked, so frequency tracking is not required when the position and size of the receiver change. Even if the system deviates from the matching condition, an efficient WPT can be realized, thereby demonstrating the robustness of the level pinning. The experimental results show that when the size ratio of the transmitter coil to the receiver coil is 4.29 (which is in the weak coupling region), the transfer efficiency of the anti-PT-symmetric system is nearly 4.3 (3.2) times higher than that of the PT-symmetric system when the matching conditions are satisfied (deviated). With the miniaturization and integration of devices in mind, a synthetic anti-PT-symmetric system is used to realize a robust WPT. Anti-PT-symmetric WPT technology based on the synthetic dimension not only provides a good research platform for the study of abundant non-Hermitian physics, but also provides a means of going beyond traditional near-field applications with resonance mechanisms, such as resonance imaging, wireless sensing and photonic routing.

Abstract
A "turn-on" aptasensor for label-free and cell-free EpCAM detection was constructed by employing magnetic α-Fe2O3/Fe3O4@Au nanocomposites as a matrix for signal amplification and double-stranded complex (SH-DNA/Apt probes) immobilization through Au-S binding. α-Fe2O3/Fe3O4@Au could be efficiently assembled into uniform and stable self-assembly films via magnetic-induced self-assembly technique on a magnetic glassy carbon electrode (MGCE). The effectiveness of the platform for EpCAM detection was confirmed through differential pulse voltammetry (DPV). Under optimized conditions, the platform exhibited excellent specificity for EpCAM, and a strong linear correlation was observed between the current and the logarithm of EpCAM protein concentration in the range 1 pg/mL-1000 pg/mL (R2 = 0.9964), with a limit of detection (LOD) of 0.27 pg/mL. Furthermore, the developed platform demonstrated good stability during a 14-day storage test, with fluctuations remaining below 93.33% of the initial current value. Promising results were obtained when detecting EpCAM in spiked serum samples, suggesting its potential as a point-of-care (POC) testing.

Abstract
The type VII protein secretion system (T7SS) is found in many Gram-positive bacteria and in pathogenic mycobacteria. All T7SS substrate proteins described to date share a common helical domain architecture at the N-terminus that typically interacts with other helical partner proteins, forming a composite signal sequence for targeting to the T7SS. The C-terminal domains are functionally diverse and in Gram-positive bacteria such as Staphylococcus aureus often specify toxic anti-bacterial activity. Here we describe the first example of a class of T7 substrate, TslA, that has a reverse domain organisation. TslA is widely found across Bacillota including Staphylococcus, Enterococcus and Listeria. We show that the S. aureus TslA N-terminal domain is a phospholipase A with anti-staphylococcal activity that is neutralised by the immunity lipoprotein TilA. Two small helical partner proteins, TlaA1 and TlaA2 are essential for T7-dependent secretion of TslA and at least one of these interacts with the TslA C-terminal domain to form a helical stack. Cryo-EM analysis of purified TslA complexes indicate that they share structural similarity with canonical T7 substrates. Our findings suggest that the T7SS has the capacity to recognise a secretion signal present at either end of a substrate.

Abstract
Trastuzumab (TRZ) is a novel targeted anti-tumor agent that significantly improve the survival of patients with human epidermal growth factor receptor (HER2) positive breast cancer. However, its clinical application is limited due to the side effects of cardiotoxicity. Osthole (OST), a coumarin derivative isolated from Cnidium monnieri (L.) Cusson, has previously demonstrated cardioprotective effects. The aim of this study was to observe the protective effect of OST on TRZ-induced cardiomyocytes damage and to explore its potential mechanism. The results showed that OST pretreatment could significantly inhibit TRZ-induced cardiomyocytes damage, markedly increase the ratio of LC3II/I and Beclin-1 protein expression, and reduce the protein expression of p62. OST pretreatment significantly attenuated oxidative stress and apoptosis induced by TRZ, as evidenced by reducing intracellular ROS level, the Bax/Bcl-2 ratio, and Caspase-3 protein expression. Additionally, OST markedly increased the phosphorylation level of p38MAPK and decreased the mTOR phosphorylation level. However, the effects of OST on enhancing autophagy, reducing oxidative stress, apoptosis, and the phosphorylation level of mTOR were reversed after the addition of 3-MA or SB203580. Molecular docking results indicated that OST exerted a good binding ability with the p38MAPK protein. Our findings suggested that OST could protect TRZ-induced cardiomyocytes damage by enhancing autophagy via the p38MAPK/mTOR signaling pathway.

Abstract
BACKGROUND Seizures are a common complication of intracerebral hemorrhage (ICH). We aimed to identify predictors of unprovoked seizures (US) after ICH in a Chinese cohort. METHODS We retrospectively included patients with ICH admitted in the Second Hospital of Hebei Medical University between November 2018 and December 2020. Incidence and risk factors of US were identified with univariate and then multiple Cox regression analysis. We used χ2 test to compare incidence of US between groups with or without prophylactic anti-seizure medications (ASM) in patients with craniotomy. RESULTS A total of 488 patients were included in the cohort, 58 (11.9%) patients developed US within 3 years after ICH. Analysis on the 362 patients without prophylactic ASM showed that craniotomy (HR 8.35, 95% CI 3.80-18.31) and acute symptomatic seizures (ASS) (HR 13.76, 95% CI 3.56-53.17) are independent predictors of US. No significant effect of prophylactic ASM use was found on incidence of US in ICH patients with craniotomy (P = 0.369). CONCLUSIONS Craniotomy and acute symptomatic seizures were independent predictors for unprovoked seizures after ICH, suggesting that more attention should be paid for such patients during follow-up. Whether prophylactic ASM treatment benefits ICH patients underwent craniotomy remains uncertain.

Abstract
The non-Hermitian skin effect (NHSE) on the non-Hermitian Haldane model with gain and loss on the honeycomb lattice with the outline of a triangle is discussed. The NHSE only occurs on the edge of the lattice, transforming the edge modes into the higher-order corner modes. The NHSE can also occur on a lattice with only loss, which can be treated as a lattice with gain and loss as well as a global loss added to it. When the saturated gain is added to the three corner sites of the dissipative lattice, a single-mode laser system is obtained. When any one site is stimulated initially, the system will reach a saturated state depending on the distribution of the corner modes, and the stable laser light is emitted by sites at the corners.

Abstract
Objective: To investigate the effects of preoperative quetiapine on postoperative delirium (POD) and sleep quality in elderly orthopedic patients. Methods: Prospectively, 111 elderly patients, American Society of Anesthesiologists (ASA) grade Ⅱ-Ⅲ, scheduled to undergo knee or hip surgery in the Affiliated Huangyan Hospital of Wenzhou Medical University under continuous spinal anesthesia from August 2021 to March 2023, were selected and randomly divided into two groups by random number table: control group (group C, 1 h preoperative placebo) and quetiapine group (group Q, 1 h preoperative quetiapine 12.5 mg). In group C, 54 cases were enrolled, including 25 males and 29 females, with an average age of (73.5±4.9) years. In group Q, 57 cases were enrolled, including 26 males and 31 females, with an average age of (74.8±5.0) years. The primary outcome measures were the incidence of POD evaluated by using confusion assessment method (CAM) at 24, 48, and 72 hours after surgery, and the secondary outcome measures included Pittsburgh sleep quality index (PSQI) scores at 24 and 48 hours after surgery and satisfaction of pain management within 24 hours after surgery. Results: The incidence of POD at 24, 48, and 72 h after surgery in group Q was 5.4% (3/57), 12.5% (7/57), 14.3% (8/57), respectively, while that in group C was 18.2% (10/54), 21.8% (12/54), 21.8% (12/54), respectively. The incidence of POD at 24 h after surgery in group Q was lower than that in group C (P=0.036). There was no significant difference in the incidence of POD at 48 and 72 h after surgery between two groups (all P>0.05). The PSQI score of patients in group Q at 24 and 48 h after surgery were (3.8±1.2) and (6.9±1.1) scores, respectively, which in group C were (10.5±2.8) and (7.3±1.3) scores, respectively. Compared with group C, the PSQI score of patients in group Q at 24 h after surgery was significantly higher (P<0.001), but there was no significant difference at 48 h after surgery (P=0.068). The satisfaction scores of pain management at 24 h after surgery in group Q was (91±7) scores, which was higher than that in group C of (81±6) scores (P<0.001). Conclusion: Oral intake of low-dose quetiapine 1 h preoperatively can reduce the incidence of POD, improve postoperative sleep quality and enhance postoperative satisfaction of pain management at 24 hours after surgery in elderly orthopedic patients undergoing knee or hip surgery.

Abstract
A significant amount of textual data has been produced in the biomedical area recently as a result of the advancement of biomedical technologies. Large-scale biomedical data can be automatically obtained with the help of distant supervision. However, the noisy data brought by distant supervision methods makes relation extraction tasks more difficult. Previous work has focused more on how to restore mislabeled relationships, but little attention has been paid to the importance of labeled entity locations for relationship extraction tasks. In this paper, we present a "four-stage" model based on BioBERT and Multi-Instance Learning by using entity position markers. Firstly, the sentence is marked with position. Secondly, BioBERT, a biomedical pre-trained language model, is used in the final sentence feature vector representation not only with the global position marker but also with the start and end marker of both the head and tail entity. Thirdly, the aggregation of sentence vectors in the bag is used as the vector feature of the bag by three aggregation methods, and the performance of different sentence feature vectors combined with different bag encoding methods is discussed. At last, relation classification is performed at the bag level. According to experimental results, the presented model significantly outperforms all baseline models and contributes to noise reduction. In addition, different bag encoding methods need to match corresponding sentence encoding representation to achieve the best performance.

Abstract
IMPORTANCE Staphylococcus aureus is an opportunistic human pathogen associated with severe infections and antimicrobial resistance. S. aureus strains utilize a type VII secretion system to secrete toxins targeting competitor bacteria, likely facilitating colonization. EsaD is a nuclease toxin secreted by the type VII secretion system in many strains of S. aureus as well as other related bacterial species. Here, we identify three small proteins of previously unknown function as export factors, required for efficient secretion of EsaD. We show that these proteins bind to the transport domain of EsaD, forming a complex with a striking cane-like conformation.

Abstract
Hipposideros pratti has low genetic diversity and was divided into two clades, the central-western clade and the eastern clade. We did not detect a clear east-to-west dispersal route along the longitudinal direction, and we found that the eastern clade spread outward from one population to another, while the central-western clade spread gradually. The glacial-interglacial period of the Quaternary influenced the migration and dispersal of H. pratti. H. pratti did not experience a significant population increase in the past, and the average population trajectory was decreasing. Given the convenient ecosystem services provided by bats, the preservation of bat populations is particularly critical. Nonetheless, we have discovered that the majority of H. pratti's distributional sites were not discovered in this study. Based on our results, it is important to apply in situ conservation measures for effective protection as soon as possible.

Abstract
White light cavities with broadband resonance are usually filled with negative dispersion medium, which inevitably leads to gain. In this article, pure passive white light cavities are designed, in which negative dispersion medium is no longer necessary. Theoretically, if the reflection phase of the cavity wall can exhibit a negative dispersion slope, then it can also satisfy white light cavities conditions without medium. In practice, the negative dispersion property of the cavity wall can be realized by two metal coatings with different reflection coefficients. Therefore, our white light cavities are composite cavities, in which the main cavity provides resonance while the auxiliary cavity forms the cavity wall, providing negative dispersion reflection phase. Further, atomic gas can be employed to improve the performance of the white light cavities. Atomic gas exploits effects such as Electromagnetic Induced Transparency (EIT), enabling the white light cavities to be controlled by coherent driving field. With the passive characters, our design can be realized and implemented much more easily.

Abstract
BACKGROUND Compared to nonsocial information, the human brain is more highly sensitive to social information. As a kind of typical social semantic information, the words describing person traits differ from the nonsocial semantic information describing inanimate objects in many ways. It remains to be seen whether the processing of trait words has a valence asymmetric and whether it differs from the processing of nonsocial semantic information in terms of behavioral responses and neural temporal processes. METHOD Taking person and object names as priming stimuli and adjective words only used for describing humans or objects as target stimuli, the present study aimed to investigate the processing characteristics of social and nonsocial semantic information by recording both behavioral and ERP data. RESULTS Behavioral results showed that the response times for negative words were significantly slower than those for positive words whether for social or nonsocial semantic information. The accuracy rates of negative words were significantly lower than those of positive words when the targets were social words which is contrary to the nonsocial words. The ERP results indicated that there was a negative bias effect on the processing of both types of information during the whole time course of brain neural activity; that is, the P2, N400, and LPP amplitudes elicited by negative words were larger than those elicited by positive words; However, the negative bias effect of social semantic information started at the early perceptual stage which was significantly earlier than the onset of negative bias of nonsocial semantic information, and was significantly affected by the prime type. In addition, there was a significant semantic conflict N400 effect only for nonsocial semantic information. CONCLUSIONS Overall, the present study revealed the existence of an early negative bias of social information and provided evidence for the specificity of social information.

Abstract
Van der Waals assembly enables the design of electronic states in two-dimensional (2D) materials, often by superimposing a long-wavelength periodic potential on a crystal lattice using moiré superlattices1-9. This twistronics approach has resulted in numerous previously undescribed physics, including strong correlations and superconductivity in twisted bilayer graphene10-12, resonant excitons, charge ordering and Wigner crystallization in transition-metal chalcogenide moiré structures13-18 and Hofstadter's butterfly spectra and Brown-Zak quantum oscillations in graphene superlattices19-22. Moreover, twistronics has been used to modify near-surface states at the interface between van der Waals crystals23,24. Here we show that electronic states in three-dimensional (3D) crystals such as graphite can be tuned by a superlattice potential occurring at the interface with another crystal-namely, crystallographically aligned hexagonal boron nitride. This alignment results in several Lifshitz transitions and Brown-Zak oscillations arising from near-surface states, whereas, in high magnetic fields, fractal states of Hofstadter's butterfly draw deep into the bulk of graphite. Our work shows a way in which 3D spectra can be controlled using the approach of 2D twistronics.

Abstract
Objective The present study investigated the impact of emotion concepts obtained from external environmental experiences on the perception of facial expressions by manipulating the activation and satiation of emotion words, which was based on the argument between basic emotion theory and constructed emotion theory. Methods Experiment 1 explored the effects of emotion activation on happy, disgusted, emotion-label words and emotion-laden words in a facial expression judgment task through behavioral experimentation. Experiment 2 explored the effect of semantic satiation on emotion-label words and emotion-laden words using the event-related potential technique. Results Experiment 1 found that facial expression perception was influenced by both types of emotion words and showed a significant emotional consistency effect. Experiment 2 found that N170 exhibited a more negative amplitude in the consistent condition compared to the inconsistent condition in the right hemisphere. More importantly, in the later stage of facial expression processing, emotion-label words and emotion-laden words both obstructed the perception of disgusted facial expressions and elicited more negative N400 amplitude in the emotion consistency condition, showing a reversed N400 effect. Conclusion These results suggested that emotion concepts in the form of language influenced the perception of facial expressions, but there were differences between happy and disgusted faces. Disgusted faces were more dependent on emotion concept information and showed different performances in semantic activation and satiation conditions.

Abstract
The type VIIb protein secretion system (T7SSb) plays a role in interbacterial competition in Gram-positive Firmicute bacteria and secretes various toxic effector proteins. The mechanism of secretion and the roles of numerous conserved genes within T7SSb gene clusters remain unknown. EsaD is a nuclease toxin secreted by the Staphylococcus aureus T7SSb, which forms a complex with its cognate immunity protein, EsaG, and chaperone EsaE. Encoded upstream of EsaD are three small secreted proteins, EsxB, EsxC and EsxD. Here we show that EsxBCD bind to the transport domain of EsaD and function as EsaD export factors. We report the first structural information for a complete T7SSb substrate pre-secretion complex. Cryo-EM of the EsaDEG trimer and the EsaDEG-EsxBCD hexamer shows that incorporation of EsxBCD confers a conformation comprising a flexible globular cargo domain attached to a long narrow shaft that is likely to be crucial for efficient toxin export.

Abstract
Background Women with atypical hyperplasia (AH) is associated with a higher risk of future breast cancer. However, whether AH found at margins in patients with breast-conserving surgery (BCS) after neoadjuvant chemotherapy (NAC) needs re-excision is not well-defined. The aim of the present study was to evaluate the impact of AH at the surgical margins on the local recurrence and survival outcomes in breast cancer patients treated with NAC and BCS. Methods A retrospective analysis comparing patients who treated with NAC and BCS with AH at the margins to those without AH was performed. Results 598 patients were included in this study. The 5-year rates of ipsilateral breast tumor recurrence (IBTR) were 4.6% and 6.2% in patients with and without AH, respectively. No significant differences were observed among the two groups in terms of IBTR, DMFS, or OS. HER2 overexpressing breast cancer patients with severe AH at margins have a significantly higher risk of IBTR compared to those without severe AH. Conclusion Our study suggests that the presence of AH at the surgical margins of BCS in patients who received NAC does not appear to increase the risk of ipsilateral breast cancer. Therefore, there is no need for surgeons to routinely perform additional re-excision of AH found at the margins of BCS in these patients. However, selective re-excision should be considered in certain cases, particularly in patients with HER2 overexpression.

Abstract
Under the political system with Chinese characteristics, the turnover of regional officials becomes a norm. So the uncertainty generated by the turnover of officials can often have an impact on the pollution emissions of regional enterprises. This paper examines the impact of official turnover on corporate pollution emissions using the Chinese industrial enterprise database and pollution emission database from 2004 to 2014 in China, while matching urban panel data of prefecture-level cities. The empirical study finds that official turnover significantly reduces the pollution emission of enterprises in that year, while the effect of official turnover from economically developed to economically backward regions and from economically backward to economically developed regions on enterprises' pollution emissions is significantly different. Also, this paper finds that the turnover of officials has a short-term effect on the reduction of corporate pollution emissions. The pollution abatement effect of official turnover is more pronounced in non-resource cities and non-state enterprises. Further analysis reveals that the pollution reduction effect of official turnover is more pronounced when the age of officials is greater than the promotion age threshold of 54 years. Finally, a series of robustness tests were conducted in this paper, while the Heckman two-step method was used to test for endogeneity, and the conclusions reached remained consistent with the benchmark regression.

Abstract
Abstract
Background: The HER2-targeted drugs selection after trastuzumab failure has become a challenging issue for HER2-positive metastatic breast cancer (MBC) patients. Inetetamab is a neotype of HER2-targeted monoclonal antibody with an engineered Fc segment that optimizes the antibody-dependent cell-mediated cytotoxicity (ADCC) effect, which was important for disease control. Moreover, HER2-targeted tyrosine kinase inhibitors, as pyrotinib, were found to further improve the ADCC effect of monoclonal antibodies in pre-clinical researches, indicating that the combination of pyrotinib and inetetamab could achieve complementarity and synergy effects in terms of short-term tumor killing effect and long-term immunotherapy benefits. Therefore, the combined treatment pattern of the two drugs has potential clinical benefits. Methods: This is a prospective, multi-center, single-arm clinical study designed to evaluate the efficacy and safety of pretreated patients with HER2-positive MBC. We recruited patients with pathologically confirmed HER2-positive MBC who had received 1-3 prior regimens for metastatic disease, which must include trastuzumab. The enrolled patients received 6 cycles of Inetetamab combined with pyrotinib and chemotherapy, subsequent maintenance therapy should be considered according to tolerability. The chemotherapy drugs were decided by physicians’ choice, and could be microtubules, anthracyclines, or antimetabolites. The primary endpoint was objective response rate (ORR) after 6 cycles of treatment, secondary endpoints included progression-free survival (PFS), overall survival (OS), and clinical benefit rate (CBR) and adverse events (AEs). Results: 57 patients were enrolled from October 2020 to July 2022. And 45 patients were available for response evaluation. The ORR and DCR were 53.5 % (24/45) and 86.7 % (39/45), respectively after 6 cycles treatment. The median PFS was 7.3 months. The incidence of grade Ⅲ-Ⅳ AEs was 15.8 %. The most common treatment-related AEs were diarrhea, anemia, neutropenia, leukopenia, hand and foot syndrome. No patient’ s left ventricle ejection fraction (LVEF) decreased to < 50% or decreased by >15%. And no significant decline in quality of life score was reported. Conclusion: Inetetamab combined with pyrotinib and chemotherapy showed a promising efficacy and a good tolerance in patients with HER2-positive metastatic breast cancer, confirming the synergistic effect between the ADCC optimized monoclonal antibodies and TKIs, which brings more treatment options for HER2-positive metastatic breast cancer.

Abstract
Abstract
Background: FCN-437c is a second-generation CDK4/6 inhibitor. Phase 1b clinical results indicated improved antitumor activity in patients (pts) with HR+, HER2– advanced breast cancer (ABC), treated with FCN-437c + letrozole.
Methods: This Phase 2, multicenter, open-label clinical study evaluated the antitumor activity, pharmacokinetics (PK), and safety of FCN-437c + fulvestrant in post-menopausal pts (Cohort 1, treatment-naïve or 2L), FCN-437c + letrozole + goserelin in pre-menopausal pts (Cohort 2, treatment-naïve). Pts received FCN-437c (200 mg QD) in a 21-day-on and 7-day-off schedule either in combination with fulvestrant (500 mg D1) or letrozole (2.5 mg QD) + goserelin (3.6 mg once per cycle) in 28-day cycles. The primary endpoint was overall response rate (ORR) and secondary endpoints were progression-free survival (PFS), overall survival (OS), PK, and safety.
Results: At study cutoff (Feb 7, 2022), 36 pts were enrolled in Cohort 1 and 31 pts were in Cohort 2; 42 (62.7%) pts had visceral metastases and 9 (13.4%) pts had bone-only metastases. In Cohort 1, 18 pts were treatment-naïve, 15 pts had received 1L treatment, and 3 pts had received ≥2L treatment. In Cohort 2, 25 pts were treatment-naïve and 6 pts had received 1L treatment. Overall, 27 pts in the per-protocol set achieved partial response (PR), resulting in an ORR of 40.9% (95% CI, 29.0-53.7). Median follow-up was 12.8 months, and median PFS (mPFS), OS, and DOR were not reached. However, at 12 months, the PFS rate was 67.7% (95% CI, 53.2-78.6) and the OS rate was 95.9% (95% CI, 84.5-99.0); the 6-month DOR rate was 96.0% (95% CI, 74.8-99.4). In Cohort 1 (n=35), 11 pts achieved PR: the ORR was 31.4% (16.9-49.3%) and mPFS was 12.9 months (95% CI, 9.2-NR); the 6-month DOR rate was 100%. In Cohort 2 (n=31), 16 pts achieved PR: the ORR was 51.6% (95% CI, 33.1-69.9%). mPFS, OS, and DOR were not reached; the 6-month DOR rate was 92.9% (95% CI, 59.08-98.96) (Table). Treatment-emergent adverse events (TEAEs) were observed in all pts. Majority of AE were G1 or 2 except for hematological TEAE. 58 (86.6%) pts reported grade ≥3 TEAEs, mainly neutropenia (74.6%), leukopenia (49.3%), hypertriglyceridemia (6.0%), lymphocyte count decrease (4.5%), and γ-glutamyltransferase increase (3.0%): most were reversed through dose interruption and symptomatic therapy. Steady-state PK parameters were analyzed after 15-21 days of QD administration: Cohort 1: median Tmax was 3 h, geomean T1/2 was 44.6 h, geomean Cmax was 1650.7 ng/mL, and geomean AUC0-24h was 29,148.08 h*ng/mL; the geomean accumulation ratios of AUC0-24h and RCmax were 2.18 and 1.74, respectively, compared with first dose. Cohort 2: median Tmax was 4 h, geomean T1/2 was 35.7 h, geomean Cmax was 1314.34 ng/mL, and geomean AUC0-24h was 22,889.96 h*ng/mL; the geomean accumulation ratios of AUC0-24h and RCmax were 1.95 and 1.63, respectively, compared with first dose.
Conclusion: FCN-437c in combination with fulvestrant or letrozole + goserelin demonstrates antitumor activity and safety and is well tolerated in pts with HR+, HER2– ABC. This combination therapy will be further investigated in 2 ongoing Phase 3 trials (NCT05438810 and NCT05439499).

Abstract
Threat-related attentional bias is thought to have a causal influence on the etiology of social anxiety. However, there is uncertainty on whether attention dwells on or diverts away from threats, and the measurements typically utilized to explore attentional bias cannot continuously quantify changes in attention. Here, we used steady-state visual evoked potentials (ssVEPs) as a continuous neurophysiological measure of visual attentional processing to examine the time course of attentional bias in social anxiety. Participants with high (n = 18) and low (n = 18) social anxiety passively viewed two faces flickering at 15 and 20 Hz frequency to evoke ssVEPs, and completed Attentional Control Scale. The results showed that angry faces, as compared to happy and neutral faces, elicited larger ssVEP amplitudes for the time window of 180-500 ms after facial stimuli onset only in the high socially anxious individuals, and the effect extended to the next two periods of 500-1000 ms and 1000-1500 ms. The ssVEP amplitudes differed most when individuals with high social anxiety viewed angry-neutral expression combinations. Additionally, attentional control was negatively correlated with social anxiety and threat-related attentional bias. The results suggested that individuals with social anxiety initially oriented attention toward the threat and subsequently exhibited difficulty in disengaging attention from it, possibly due to impaired attentional control.

Abstract
A nonlinear non-Hermitian topological laser system based on the higher-order corner states of the 2-dimensional (2D) Su-Schrieffer-Heeger (SSH) model is investigated. The topological property of this nonlinear non-Hermitian system described by the quench dynamics is in accordance with that of a normal 2D SSH model. In the topological phase, all sites belonging to the topological corner states begin to emit stable laser light when a pulse is given to any one site of the lattice, while no laser light is emitted when the lattice is in the trivial phase. Furthermore, the next-nearest-neighbor (NNN) couplings are introduced into the strong-coupling unit cells of the 2D SSH model, which open a band gap in the continuous band structure. In the topological phase, similar to the case of 2D SSH model without NNN couplings, the corner sites can emit stable laser light due to the robustness of the higher-order corner states when the NNN couplings are regarded as the perturbation. However, amplitude of the stimulated site does not decay to zero in the trivial phase, because the existence of the NNN couplings in the strong-coupling unit cells make the lattice like one in the tetramer limit, and a weaker laser light is emitted by each corner.

Abstract
Durability is crucial for the long-term application of cathode oxygen reduction reaction (ORR) catalysts in fuel cells. In this work, sulfur was successfully doped into reduced graphene oxide (rGO) aerogels to achieve the formation of 1T/2H hybrid phase MoS2 , obtaining MoS2 @S-rGO-300 composite ORR catalyst support. After loading ultrafine Pt nanoparticles, Pt/MoS2 @S-rGO-300 showed not only an enhanced ORR activity, but also a significantly improved stability after 10000 cycles. The mass activity retention for Pt/MoS2 @S-rGO-300 after cycles reached 89.94 %, while that of Pt/rGO was only 37.44 %. Density functional theory calculations revealed that the enlarged binding energy between Pt atoms and MoS2 @S-rGO-300 led to the prevention of Pt agglomeration as well as Ostwald ripening.

Abstract
The wavelength of defect mode in all-dielectric photonic crystals (PCs) with a dielectric defect are blue-shifted as incident angle increases for both transverse electric and transverse magnetic (TM) polarized waves. The blue-shifted property of defect mode limits the design of some optical devices including omnidirectional optical filters and wide-angle polarization selectors. Here we introduce a hyperbolic metamaterial (HMM) layer as a defect into dielectric one-dimensional photonic crystals (1DPCs) to obtain an omnidirectional defect mode for TM polarized waves at near-infrared regimes. Since only one HMM layer is introduced, omnidirectional defect mode with transmittance as high as 71% can be realized. Because of the unusual angle-dependence of propagating phase in the HMM defect, the total phase for satisfying the resonance condition of defect mode can be unchanged in a wide-angle range at a fixed wavelength, which leads to the omnidirectional defect mode. Moreover, the manipulation of propagating phase can be generalized to the case of circularly polarized waves, and we obtain an omnidirectional defect mode for left-handed circularly polarized waves in 1DPCs with a chiral hyperbolic metamaterial defect. Nevertheless, the defect mode for right-handed circularly polarized waves is still blue-shifted. Such spin-selective omnidirectional defect mode can be utilized to greatly enhance circular dichroism in a wide-angle range up to 64.1°. Our structure facilitates the design of omnidirectional optical filters with a high transmittance and circular polarization selectors working in a wide-angle range.

Abstract
Inflammation is one of the pathogenic processes in Parkinson's disease (PD). Dopamine receptor agonist pramipexole (PPX) is extensively used for PD treatment in clinics. A number of studies show that PPX exerts neuroprotection on dopaminergic (DA) neurons, but the molecular mechanisms underlying the protective effects of PPX on DA neurons are not fully elucidated. In the present study, we investigated whether PPX modulated PD-related neuroinflammation and underlying mechanisms. PD model was established in mice by bilateral striatum injection of lipopolyssaccharide (LPS). The mice were administered PPX (0.5 mg·kg-1·d-1, i.p.) 3 days before LPS injection, and for 3 or 21 days after surgery, respectively, for biochemical and histological analyses. We showed that PPX administration significantly alleviated the loss of DA neurons, and suppressed the astrocyte activation and levels of proinflammatory cytokine IL-1β in the substantia nigra of LPS-injected mice. Furthermore, PPX administration significantly decreased the expression of NLRP3 inflammasome-associated proteins, i.e., cleaved forms of caspase-1, IL-1β, and apoptosis-associated speck-like protein containing a caspase recruit domain (ASC) in the striatum. These results were validated in LPS+ATP-stimulated primary mouse astrocytes in vitro. Remarkably, we showed that PPX (100-400 μM) dose-dependently enhanced the autophagy activity in the astrocytes evidenced by the elevations in LC3-II and BECN1 protein expression, as well as the increase of GFP-LC3 puncta formation. The opposite effects of PPX on astrocytic NLRP3 inflammasome and autophagy were eliminated by Drd3 depletion. Moreover, we demonstrated that both pretreatment of astrocytes with autophagy inhibitor chloroquine (40 μM) in vitro and astrocyte-specific Atg5 knockdown in vivo blocked PPX-caused inhibition on NLRP3 inflammasome and protection against DA neuron damage. Altogether, this study demonstrates an anti-neuroinflammatory activity of PPX via a Drd3-dependent enhancement of autophagy activity in astrocytes, and reveals a new mechanism for the beneficial effect of PPX in PD therapy.

Abstract
Anthracycline is a mainstay of treatment for breast cancer patients because of its antitumor activity. However, anthracycline resistance is a critical barrier in treating breast cancer. Thus, it is of great importance to uncover the molecular mechanisms underlying anthracycline resistance in breast cancer. Herein, we integrated transcriptome data, genetic alterations data, and clinical data of The Cancer Genome Atlas (TCGA) to identify the molecular mechanisms involved in anthracycline resistance in breast cancer. Two hundred and four upregulated genes and 1376 downregulated genes were characterized between the anthracycline-sensitive and anthracycline-resistant groups. It was found that drug resistance-associated genes such as ABCB5, CYP1A1, and CYP4Z1 were significantly upregulated in the anthracycline-resistant group. The gene set enrichment analysis (GSEA) suggested that the P53 signaling pathway, DNA replication, cysteine, and methionine metabolism pathways were associated with anthracycline sensitivity. Somatic TP53 mutation was a common genetic abnormality observed in the anthracycline-sensitive group, while CDH1 mutation was presented in the anthracycline-resistant group. Immune infiltration patterns were extremely different between the anthracycline-sensitive and anthracycline-resistant groups. Immune-associated chemokines and cytokines, immune regulators, and human leukocyte antigen genes were significantly upregulated in the anthracycline-sensitive group. These results reveal potential molecular mechanisms associated with anthracycline resistance.

Abstract
CD19-directed chimeric antigen receptor (CAR) T cell therapy has been shown to achieve a considerably durable response in patients with refractory or relapsed B cell non-Hodgkin lymphomas, as seen from the results of Zuma-1, Zuma-5, and other clinical trials. Most of these CARs were generated by lentivirus or reverse adenovirus. It is rare to see CARs using non-viral vectors, such as Piggy Bac (pb), in treating lymphoma patients with active diseases. Generally, patients with a high tumor burden tend to have a higher rate of severe cytokine release syndrome (CRS) or neurological events as reported in the literature. Patients with symptomatic pleural effusions are excluded from the Zuma-1 trial because of the risk of severe CRS. We report here that a patient with relapsed follicular lymphoma with bulky disease and massive chylous ascites failed several lines of chemotherapy. After infusion of the CD19-directed pbCAR-T cells at 6 × 106 cells/kg, the patient had a rapid response and achieved a nearly complete metabolic remission on day 28. There was only grade 1 CRS, and no neurotoxicity occurred. The CAR-T cells reached a peak level on day 14 and spread into the ascites and expanded for 3 months. This might be the first case reported for pbCAR-T cells to treat relapsed follicular lymphoma directly. The long-term efficacy will be observed, and more patients be tested in the future.

Abstract
Social role theory posits that binary gender gaps in agency and communion should be larger in less egalitarian countries, reflecting these countries’ more pronounced sex-based power divisions. Conversely, evolutionary and self-construal theorists suggest that gender gaps in agency and communion should be larger in more egalitarian countries, reflecting the greater autonomy support and flexible self-construction processes present in these countries. Using data from 62 countries ( N = 28,640), we examine binary gender gaps in agentic and communal self-views as a function of country-level objective gender equality (the Global Gender Gap Index) and subjective distributions of social power (the Power Distance Index). Findings show that in more egalitarian countries, gender gaps in agency are smaller and gender gaps in communality are larger. These patterns are driven primarily by cross-country differences in men’s self-views and by the Power Distance Index (PDI) more robustly than the Global Gender Gap Index (GGGI). We consider possible causes and implications of these findings.

Abstract
Objective: To verify Baveno VI criteria, Expanded-Baveno VI criteria, liver stiffness×spleen diameter-to-platelet ratio risk score (LSPS), and platelet count/spleen diameter ratio (PSR) in evaluating the severity value of esophageal varices (EV) in patients with non-cirrhotic portal hypertension (NCPH). Methods: 111 cases of NCPH and 204 cases of hepatitis B cirrhosis who met the diagnostic criteria were included in the study. NCPH included 70 cases of idiopathic non-cirrhotic portal hypertension (INCPH) and 41 cases of nontumoral portal vein thrombosis (PVT). According to the severity of EV on endoscopy, they were divided into the low-bleeding-risk group (no/mild EV) and the high-bleeding-risk group (moderate/severe EV). The diagnostic value of Baveno VI and Expanded-Baveno VI criteria was verified to evaluate the value of LSPS and PSR for EV bleeding risk severity in NCPH patients. The t-test or Mann-Whitney U test was used to compare the measurement data between groups. Comparisons between counting data groups were performed using either the χ2 test or the Fisher exact probability method. Results: Considering endoscopy was the gold standard for diagnosis, the missed diagnosis rates of low/high bleeding risk EVs in INCPH/PVT patients with Baveno VI and Expanded-Baveno VI criteria were 50.0%/30.0% and 53.8%/50.0%, respectively. There were no statistically significant differences in platelet count (PLT), spleen diameter, liver stiffness (LSM), LSPS, and PSR between low-bleeding-risk and high-bleeding-risk groups in INCPH patients, and the area under the receiver operating characteristic curve (AUC) of LSPS and PSR was 0.564 and 0.592, respectively (P=0.372 and 0.202, respectively). There were statistically significant differences in PLT, spleen diameter, LSPS, and PSR between the low and high-bleeding risk groups in PVT patients, and the AUCs of LSPS and PSR were 0.796 and 0.833 (P=0.003 and 0.001, respectively). In patients with hepatitis B cirrhosis, the Baveno VI and Expanded-Baveno VI criteria were used to verify the low bleeding risk EV, and the missed diagnosis rates were 0 and 5.4%, respectively. There were statistically significant differences in PLT, spleen diameter, LSM, LSPS and PSR between the low-bleeding-risk and high-bleeding-risk groups (P<0.001). LSPS and PSR AUC were 0.867 and 0.789, respectively (P<0.05). Conclusion: Baveno VI and Expanded-Baveno VI criteria have a high missed diagnosis rate for EVs with low bleeding risk in patients with INPCH and PVT, while LSPS and PSR have certain value in evaluating EV bleeding risk in PVT patients, which requires further clinical research.

A cohort of 470 Chinese college students was selected as subjects based on the second edition of the Big Five Inventory-2, the Chinese version of the Metacognitions about Smartphone Use Questionnaire, and the general functioning subscale of Family Assessment Device. The results showed that only neuroticism was significantly and positively correlated with positive metacognition, while the correlation between other personality traits and positive metacognition was not statistically significant. Except for openness, the correlation between other personality traits and negative metacognition was statistically significant. In addition, conscientiousness, extraversion, and neuroticism were found to directly affect negative metacognitions about smartphone use and indirectly affect the negative metacognitions about smartphone use through family functioning. Findings provide insights into the design of interventions aimed at improving metacognitions about smartphone use and preventing smartphone addiction among college students.

Abstract
BACKGROUND In medical genetics, discovery and characterization of disease trait contributory genes and alleles depends on genetic reasoning, study design, and patient ascertainment; we suggest a segmental haploid genetics approach to enhance gene discovery and molecular diagnostics. METHODS We constructed a genome-wide map for nonallelic homologous recombination (NAHR)-mediated recurrent genomic deletions and used this map to estimate population frequencies of NAHR deletions based on large-scale population cohorts and region-specific studies. We calculated recessive disease carrier burden using high-quality pathogenic or likely pathogenic variants from ClinVar and gnomAD. We developed a NIRD (NAHR deletion Impact to Recessive Disease) score for recessive disorders by quantifying the contribution of NAHR deletion to the overall allele load that enumerated all pairwise combinations of disease-causing alleles; we used a Punnett square approach based on an assumption of random mating. Literature mining was conducted to identify all reported patients with defects in a gene with a high NIRD score; meta-analysis was performed on these patients to estimate the representation of NAHR deletions in recessive traits from contemporary human genomics studies. Retrospective analyses of extant clinical exome sequencing (cES) were performed for novel rare recessive disease trait gene and allele discovery from individuals with NAHR deletions. RESULTS We present novel genomic insights regarding the genome-wide impact of NAHR recurrent segmental variants on recessive disease burden; we demonstrate the utility of NAHR recurrent deletions to enhance discovery in the challenging context of autosomal recessive (AR) traits and biallelic variation. Computational results demonstrate new mutations mediated by NAHR, involving recurrent deletions at 30 genomic regions, likely drive recessive disease burden for over 74% of loci within these segmental deletions or at least 2% of loci genome-wide. Meta-analyses on 170 literature-reported patients implicate that NAHR deletions are depleted from the ascertained pool of AR trait alleles. Exome reanalysis of personal genomes from subjects harboring recurrent deletions uncovered new disease-contributing variants in genes including COX10, ERCC6, PRRT2, and OTUD7A. CONCLUSIONS Our results demonstrate that genomic sequencing of personal genomes with NAHR deletions could dramatically improve allele and gene discovery and enhance clinical molecular diagnosis. Moreover, results suggest NAHR events could potentially enable human haploid genetic screens as an approach to experimental inquiry into disease biology.

Abstract
PURPOSE SRRM2 encodes the SRm300 protein, a splicing factor of the SR-related protein family characterized by its serine- and arginine-enriched domains. It promotes interactions between messenger RNA and the spliceosome catalytic machinery. This gene, predicted to be highly intolerant to loss of function (LoF) and very conserved through evolution, has not been previously reported in constitutive human disease. METHODS Among the 1000 probands studied with developmental delay and intellectual disability in our database, we found 2 patients with de novo LoF variants in SRRM2. Additional families were identified through GeneMatcher. RESULTS Here, we report on 22 patients with LoF variants in SRRM2 and provide a description of the phenotype. Molecular analysis identified 12 frameshift variants, 8 nonsense variants, and 2 microdeletions of 66 kb and 270 kb. The patients presented with a mild developmental delay, predominant speech delay, autistic or attention-deficit/hyperactivity disorder features, overfriendliness, generalized hypotonia, overweight, and dysmorphic facial features. Intellectual disability was variable and mild when present. CONCLUSION We established SRRM2 as a gene responsible for a rare neurodevelopmental disease.

Abstract
The resonance fluorescence properties in the steady-state regime are investigated for a driven cascaded exciton-biexciton quantum dot coupled to the two-dimensional black phosphorus metasurfaces. It is shown that for the material parameters under consideration, both the elliptic and hyperbolic dispersion patterns of the surface plasmon modes are achievable according to the variation of the carrier concentration. Further study on the Purcell factor indicates unequal enhancements in the spontaneous decay of the orthogonal in-plane dipoles. Motivated by this intriguing phenomenon, we then investigate the steady-state properties of the driven quantum dot, where the populations of the dressed levels are highly tunable by engineering the anisotropy of the surfaces. As a result, the manipulation of the carrier concentration will lead to strong modifications in the resonance fluorescence. Under certain conditions, one can observe the squeezing of two-mode noise spectra with different resonances and polarizations. Although at the expense of declines in the photon-sideband detunings, it is feasible to enhance the two-mode squeezing by gate doping. Our proposal can be easily extended to other hybrid systems containing anisotropic metasurfaces, which are important for the development of quantum information science.

Abstract
We propose that the squeezed light accompanied by hyperradiance is induced by quantum interference in a linear system consisting of a high-quality optical cavity and two coherently driven two-level qubits. When two qubits are placed in the cavity with a distance of integer multiple and one-half of wavelengths (i.e., they have the opposite coupling coefficient to the cavity), we show that squeezed light is generated in the hyperradiance regime under the conditions of strong coupling and weak driving. Simultaneously, Klyshko's criterion alternates up and down at unity when the photon number is even or odd. Moreover, the orthogonal angles of the squeezed light can be controlled by adjusting the frequency detuning between the driving field and the qubits. It can be implemented in a variety of quantum systems, including but not limited to two-level systems such as atoms, ions, quantum dots in single-mode cavities.

Abstract
Background Immune checkpoint inhibitors that target programmed cell death protein 1 (PD-1) have obtained encouraging results, but a fraction of tumor patients failed to respond to anti-PD-1 treatment due to the existence of multiple immune suppressive elements such as myeloid-derived suppressor cells (MDSCs). Traditional Chinese medicine or natural products from medicinal plants could enhance immunity and may be helpful for cancer immunotherapy. As a digestive metabolite from cruciferous plants, 3,3′-diindolylmethane (DIM) has been widely used in chemotherapy, but its influence on cancer immunotherapy remains unclear. Here we investigate the function of DIM on MDSCs and examine the therapeutic effects of DIM in conjunction with PD-1 antibody against mouse tumors. Methods Flow cytometry analysis, Western blot analysis and qRT-PCR assay were used to examine the inhibitory effects and mechanisms of DIM on MDSCs in vitro and in vivo. The therapeutic effects of DIM on cancer immunotherapy by PD-1 antibody were evaluated in mouse models of breast cancer and melanoma tumor. Results DIM exerted the inhibitory effect on MDSCs via downregulating miR-21 level and subsequently activating PTEN/PIAS3-STAT3 pathways. Adoptive transfer of MDSCs impaired the therapeutic effects of DIM, indicating that the antitumor activity of DIM might be due to the suppression of MDSCs. Furthermore, in mouse models of breast cancer and melanoma tumor, the addition of DIM can enhance the therapeutic effect of PD-1 antibody through promoting T cells responses, and thereby inhibiting tumor growth. Conclusions Overall, the strategy based on the combination treatment of anti-PD-1 antibody and DIM may provide a new approach for cancer immunotherapy. Cruciferae plants-rich diet which contains high amount of DIM precursor may be beneficial for cancer patients that undergo the anti-PD-1 treatment.

Abstract
We study the excitation conditions of the supported field modes, as well as the spontaneous decay property of a two-level quantum emitter coupled to photonic structures containing topological insulators (TIs) and left-handed materials. Within the proper field quantization scheme, the spontaneous decay rates of dipoles with different polarizations are expressed in forms of the Green's functions. We find that in the proposed structure, the variation in the topological magnetoelectric polarizability (TMP) has a deterministic effect on the excitation of different field modes. As the result, the spontaneous decay property of the quantum emitter can be engineered. For a dipole placed in different spatial regions, the spontaneous decay feature indicates a dominant contribution from the waveguide modes, the surface plasmon modes or the free vacuum modes. Moreover, a special kind of the surface plasmon modes displaying asymmetric density of states at the interfaces, becomes legal in the presence of nontrivial TIs. These phenomena manifest the feasibility in controlling dipole emissions via manipulations of the topological magnetoelectric (TME) effect. Our results have potential applications in quantum technologies relied on the accurate control over light-matter interactions.

Abstract
Accurate positioning of the catheter tip is one of the most critical procedures in central venous catheter insertion. The traditional surface measurement method frequently has a large deviation and increases the X-ray exposure of doctors and patients. In the present retrospective study, cancer patients who received a totally implantable venous access port (TIVAP) in the upper arm using intracavitary electrocardiogram (ECG) guidance were compared with those where the traditional surface measurement method was used in terms of the rate of correct placement of the catheter tip, the rate of achieving the best position, the operation time and the complications. The results indicated that the correct placement rate and the best position rate of the catheter tip at the first attempt were higher in the ECG-guided group than in the traditional surface measurement method group (95.65 vs. 82.91% and 90.58 vs. 68.38%, respectively). The mean operation time was shorter in the ECG-guided group than in the surface measurement group (46.28 vs. 63.26 min). The incidence of complications in the ECG-guided group was 6.52%, while that in the surface measurement group was 10.26%. This indicated that the intracavitary ECG-guided tip positioning technique may improve the accuracy of tip catheter placement and shorten the operation time, thus reducing ionizing radiation caused by repeated positioning. Therefore, the intracavitary ECG-guided tip positioning technique is able to effectively place the tip of the TIVAD in the upper arm, holding great promise as a clinical application.

Abstract
e17535 Background: Ovarian cancer is the most lethal gynecologic malignancy and the fifth leading cause of cancer-related death among women. Most of patients often have refractory or relapse. We have developed a CAR T cell secreting PD-1 nanoantibodies and targeting mesothelin (αPD-1-mesoCAR-T) and conducted a phase I clinical trial for evaluation of safety and efficacy of the αPD-1-mesoCAR-T cells in gynecologic tumors. Methods: This study is a single-arm, open, dose-increasing clinical study and two infusions (interval 14-35 days). Patients with advanced gynecological cancer were enrolled when immunohistochemical analysis for positive mesothelin over 70% and failed second-line treatment in Mengchao Cancer Hospital affiliated to Shanghai University and Shanghai Tenth People's Hospital affiliated to Tongji University. All patients underwent lymphodepletion before infusion at a dose of 1 to 15x106/kg. CAR copies, nanobody levels, cytokines, T lymphocyte subtypes were determined before and after infusion. Results: a total of 7 patients were enrolled so far and completed the first evaluation. After treatment, most symptoms of the patients were alleviated, two patients (#2, #3) had their lesions decreased. By RECIST 1.1, all 7 patients’ diseases became stable, and the disease control rate was 100%. The PFS of #3 patient with stable disease (SD) was 5.3 months, the patient #2 was 4.1 months. The frequent adverse events were fever, fatigue, nausea and pruritus. No sever adverse events above grade 3 occurred. The number of CAR-T cells in the peripheral blood increased significantly during day 4-14 after the infusion, and the PD-1 nanoantibody levels and the contents of INF-γ、IL-6、IL-2 and MCP-1 also increased at day 1-4. Conclusions: The preliminary clinical study showed that the aPD-1-mesoCAR-T cells are safe for the treatment of gynecologic cancer and stabilized the diseases. More data of the treatment is warrantied to continually follow up these patients.

Abstract
In the later-line setting or for patients with PD-L1-negative tumors, immunotherapy-based regimens remain ineffective against advanced triple-negative breast cancer (TNBC). In this multicentered phase II trial (NCT04303741), 46 patients with pretreated advanced TNBC were enrolled to receive camrelizumab 200 mg (day 1), and apatinib 250 mg daily, plus eribulin 1.4 mg/m2 (day 1 and 8) on a 21-day cycle until progression, or unacceptable toxicity. Primary endpoint was objective response rate (ORR) according to RECIST 1.1. Secondary endpoints included toxicities, disease control rate (DCR), clinical benefit rate, progression-free survival (PFS), and 1-year overall survival. With a median of 3 lines of prior chemotherapy in the advanced setting, 17.4% had received PD-1/PD-L1 blockade plus chemotherapy for advanced disease. The ORR was 37.0% (17/46, 95% CI 23.2-52.5). The DCR was 87.0% (40/46, 95% CI 73.7-95.1). Median PFS was 8.1 (95% CI 4.6-10.3) months. Tertiary lymphoid structure was associated with higher ORR. Patients with lower tumor PML or PLOD3 expression had favorable ORR and PFS. PD-L1 status was not associated with ORR/PFS. Grade 3/4 treatment-related adverse events occurred in 19 (41.3%) of 46 patients. Camrelizumab plus apatinib and eribulin shows promising efficacy with a measurable safety profile in patients with heavily pretreated advanced TNBC.

Abstract
Patients with hormone receptor (HR)-positive tumors breast cancer usually experience a relatively low pathological complete response (pCR) to neoadjuvant chemotherapy (NAC). Here, we derived a 10-microRNA risk score (10-miRNA RS)-based model with better performance in the prediction of pCR and validated its relation with the disease-free survival (DFS) in 755 HR-positive breast cancer patients (273, 265, and 217 in the training, internal, and external validation sets, respectively). This model, presented as a nomogram, included four parameters: the 10-miRNA RS found in our previous study, progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) status, and volume transfer constant (Ktrans). Favorable calibration and discrimination of 10-miRNA RS-based model with areas under the curve (AUC) of 0.865, 0.811, and 0.804 were shown in the training, internal, and external validation sets, respectively. Patients who have higher nomogram score (>92.2) with NAC treatment would have longer DFS (hazard ratio=0.57; 95%CI: 0.39-0.83; P=0.004). In summary, our data showed the 10-miRNA RS-based model could precisely identify more patients who can attain pCR to NAC, which may help clinicians formulate the personalized initial treatment strategy and consequently achieves better clinical prognosis for patients with HR-positive breast cancer.

Abstract
Mitochondrial permeability transition pore (mPTP) is a channel that opens at the inner mitochondrial membrane under conditions of stress. Sirtuin 3 (Sirt3) is a mitochondrial deacetylase known to play a major role in stress resistance and a regulatory role in cell death. This systematic review aims to elucidate the role of Sirt3 in mPTP inhibition. Electronic databases, including PubMed, EMBASE, Web of Science and Cochrane Library were searched up to May 2020. Original studies that investigated the relationship between Sirt3 and mPTP were included. Two reviewers independently extracted data on study characteristics, methods and outcomes. A total of 194 articles were found. Twenty-nine articles, which met criteria were included in the systematic review. Twenty-three studies provided evidence of the inhibitory effect of Sirt3 on the mPTP aperture. This review summarizes up-to-date evidence of the protective and inhibitory role of Sirt3 through deacetylating Cyclophilin D (CypD) on the mPTP aperture. Furthermore, we discuss the implications of this effect in disease.

Abstract
Background: Hypertrophic cardiomyopathy (HCM) is the most common heritable cardiomyopathy and can predispose individuals to sudden death. Most pediatric HCM patients host a known pathogenic variant in a sarcomeric gene. With the increase in exome sequencing (ES) in clinical settings, incidental variants in HCM-associated genes are being identified more frequently. Diagnostic interpretation of incidental variants is crucial to enhance clinical patient management. We sought to use amino acid-level signal-to-noise (S:N) analysis to establish pathogenic hotspots in sarcomeric HCM-associated genes as well as to refine the 2015 American College of Medical Genetics (ACMG) criteria to predict incidental variant pathogenicity. Methods and Results: Incidental variants in HCM genes (MYBPC3, MYH7, MYL2, MYL3, ACTC1, TPM1, TNNT2, TNNI3, and TNNC1) were obtained from a clinical ES referral database (Baylor Genetics) and compared to rare population variants (gnomAD) and variants from HCM literature cohort studies. A subset of the ES cohort was clinically evaluated at Texas Children’s Hospital. We compared the frequency of ES and HCM variants at specific amino acid locations in coding regions to rare variants (MAF < 0.0001) in gnomAD. S:N ratios were calculated at the gene- and amino acid-level to identify pathogenic hotspots. ES cohort variants were re-classified using ACMG criteria with S:N analysis as a correlate for PM1 criteria, which reduced the burden of variants of uncertain significance. In the clinical validation cohort, the majority of probands with cardiomyopathy or family history hosted likely pathogenic or pathogenic variants. Conclusions: Incidental variants in HCM-associated genes were common among clinical ES referrals, although the majority were not disease-associated. Leveraging amino acid-level S:N as a clinical tool may improve the diagnostic discriminatory ability of ACMG criteria by identifying pathogenic hotspots.

Abstract
The mutation rate of anaplastic lymphoma kinase (ALK) in patients with non-small cell lung cancer is 3% to 7%. Due to its low mutation rate and better long-term survival compared with epidermal growth factor receptor-positive non-small cell lung cancer patients, therefore, it's called "diamond mutation". At present, there are three generations of ALK tyrosine kinase inhibitor (TKI) drugs in the world. The first-generation ALK-TKI drug approved in China is crizotinib, and the second-generation drugs are alectinib, ceritinib and ensartinib. Among them, ensartinib is an ALK-TKI domestically developed, and its efficacy is similar to that of alectinib. The main adverse event is transient rash, and compliance to ensartinib is better from the perspective of long-term survival of patients. The manifestation of rash caused by ensartinib is different from that of other ALK-TKI drugs. In order to facilitate clinical application and provide patients with more treatment options, under the guidance of the Committee of Cancer Rehabilitation and Palliative Care of China Anti-Cancer Association, this article collects and summarizes the common adverse reactions of ensartinib. Based on the clinical practice, a clear adverse classification and specific treatment plan are formulated, in order to provide a corresponding reference for clinicians to make more comprehensive clinical decisions.

Abstract
Objective: To analyze the characteristics of allergen spectrum in patients with allergic rhinitis (AR) in Xinjiang area in recent 13 years. Methods: The skin prick test (SPT) results of 5 019 AR patients from 2007 to 2019 were retrospectively summarized, and 14 allergens of different age, gender and race were analyzed. Results: The distribution of 14 allergens was significantly different in different years, the difference was significant (P<0.05). The top three positive rates of 14 allergens were quinoa 48.2% (2 398/4 970), plantain 33.3% (1 221/3 667), and Artemisia 33.1% (1 647/4 974). There was no significant difference in the positive rate of dog epithelium between different genders and ages (χ²=0.041, P>0.05; χ²=3.8, P>0.05), the difference of other allergen in positive rates was statistically significant (all P<0.05). The positive rates of Alternaria Alternata (χ²=7.3), Penicillium Sp. (χ²=0.3), Cat Epithelium (χ²=3.1), Dust Mite (χ²=1.4), Acaroid Mite (χ²=0.5) and Cockroach (χ²=2.9) had no significant difference among different races (all P>0.05). The positive rates of other eight allergens including Artemisia Vulgaris (χ²=64.9), Chenopodium (χ²=204.1), Artemisiifolia (χ²=72.4), Plantain (χ²=87.8), Phleum Pratense L(χ²=55.4), Robinia Pseudoacacia (χ²=67.8), Canis Familiari (χ²=70.8), Dog Epithelium (χ²=15.7) were significantly different among different races (all P<0.05). Conclusion: The distribution of allergens in Xinjiang area changes with time, the main allergens are mainly herbaceous, and the distribution of allergens in patients with AR is different in gender, age and race.

Abstract
Purpose Our understanding of breast cancer in very young women (≤35 years old) remains limited. We aimed to assess the clinicopathological characteristics, molecular subtype, and treatment distribution and prognosis of these young patients compared with patients over 35 years. Methods We retrospectively analyzed non-metastatic female breast cancer cases treated at three Chinese academic hospitals between January 1, 2008, and December 31, 2018. Local recurrence-free survival (LRFS), disease-free survival (DFS), and overall survival (OS) were compared between different age groups and stratified with distinct molecular subtypes. Results A total of 11,671 women were eligible for the final analyses, and 1,207 women (10.3%) were ≤35 years at disease onset. Very young breast cancer women were more likely to be single or childless, have higher-grade disease, have more probability of lymphovascular invasion (LVI) in tumor and triple-negative subtype, and be treated by lumpectomy, chemotherapy especially more anthracycline- and paclitaxel-based chemotherapy, endocrine therapy plus ovarian function suppression (OFS), anti-HER2 therapy, and/or radiotherapy than older women (P < 0.05 for all). Very young women had the lowest 5-year LRFS and DFS among all age groups (P < 0.001 for all). When stratified by molecular subtype, very young women had the worst outcomes vs. women from the 35~50-year-old group or those from >50-year-old group for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) subtype, including LRFS, DFS, and OS (P < 0.05 for all). In terms of LRFS and DFS, multivariate analyses showed similar results among the different age groups. Conclusion Our study demonstrated that very young women with breast cancer had higher-grade tumors, more probability of LVI in tumor, and more triple-negative subtype, when compared with older patients. They had less favorable survival outcomes, especially for patients with the HR+/HER2− subtype.

Abstract
PurposeTo compare the performances of deep learning (DL) to radiomics analysis (RA) in predicting pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) based on pretreatment dynamic contrast-enhanced MRI (DCE-MRI) in breast cancer.Materials and MethodsThis retrospective study included 356 breast cancer patients who underwent DCE-MRI before NAC and underwent surgery after NAC. Image features and kinetic parameters of tumors were derived from DCE-MRI. Molecular information was assessed based on immunohistochemistry results. The image-based RA and DL models were constructed by adding kinetic parameters or molecular information to image-only linear discriminant analysis (LDA) and convolutional neural network (CNN) models. The predictive performances of developed models were assessed by receiver operating characteristic (ROC) curve analysis and compared with the DeLong method.ResultsThe overall pCR rate was 23.3% (83/356). The area under the ROC (AUROC) of the image-kinetic-molecular RA model was 0.781 [95% confidence interval (CI): 0.735, 0.828], which was higher than that of the image-kinetic RA model (0.629, 95% CI: 0.595, 0.663; P < 0.001) and comparable to that of the image-molecular RA model (0.755, 95% CI: 0.708, 0.802; P = 0.133). The AUROC of the image-kinetic-molecular DL model was 0.83 (95% CI: 0.816, 0.847), which was higher than that of the image-kinetic and image-molecular DL models (0.707, 95% CI: 0.654, 0.761; 0.79, 95% CI: 0.768, 0.812; P < 0.001) and higher than that of the image-kinetic-molecular RA model (0.778, 95% CI: 0.735, 0.828; P < 0.001).ConclusionsThe pretreatment DCE-MRI-based DL model is superior to the RA model in predicting pCR to NAC in breast cancer patients. The image-kinetic-molecular DL model has the best prediction performance.

Abstract
We improve the nonreciprocal unconventional photon blockade (UCPB) in an asymmetrical single-mode cavity with two asymmetrical arranged two-level atoms (TLAs) where cavity and atom spatial symmetry breakings are involved in. In order to get direction-dependent UCPB in asymmetrical system, we deduce two restrictions of frequency and intensity through the steady solution of the cavity QED system analytically. The former restriction is exactly the same as that of a single-atom case, and the latter restriction combined with both spatial asymmetries. Controllable UCPB in this model shows an improving nonreciprocal UCPB with wider operating regime which is promoted by two asymmetrical arranged atoms. The most innovation of this work is that the contributions of two spatial symmetry breakings are figured out clearly and they play different roles in nonreciprocal UCPB. The cavity spatial symmetry breaking and weak nonlinearity are essential to quantum nonreciprocity, while the atoms spatial symmetry is not and it only can promote such nonreciprocal UCPB. Our findings show a prospective access to manipulate quantum nonreciprocity by a couple of atoms.

Abstract
Abstract
Background: HR+/HER2+ breast cancer is a unique molecular subtype of HER2+ breast cancer, which is characterized by mild biological behavior and is sensitive to endocrine therapy. Although the standard treatment for HR+/HER2+ metastatic breast cancer is chemotherapy combined with anti-HER2 therapy, this combination is not ideal for patients because of the heavy side effects of chemotherapy. Previous studies have shown that endocrine therapy combined with anti-HER2 therapy can also bring survival benefits to these patients. However, due to the limitations of previous treatment, the optimal combination mode of endocrine and anti-HER2 therapies has not been found. Pyrotinib is the most efficient pan-HER tyrosine kinase inhibitor (TKI) with irreversible blocking of HER2, while fulvestrant is the most potent estrogen receptor (ER) inhibitor. Previous cell experiments showed the cross-talk between ER and HER2 receptor pathways, indicating that the two signal pathways were important mechanisms of drug resistance for each other. Further research showed that ER inhibitor fulvestrant had synergistic effect with HER2 inhibitor pyrotinib. Therefore, we firstly explored the efficacy and safety of pyrotinib combined with fulvestrant in the treatment of HR+/HER2+ metastatic breast cancer.Methods: Eligible patients had histologically confirmed HR+/HER2+ metastatic breast cancer with no more than one line of prior treatment for metastatic disease. Those with central nervous system metastases or any prior HER2 TKI were excluded. Patients were treated with oral pyrotinib 400 mg once daily plus intramuscular injection of fulvestrant 500 mg on days 1, 15, and 29, and once every 28 days thereafter. The primary endpoint was progression-free survival (PFS), as assessed by the data and safety monitoring committee. Secondary endpoints included objective response rate, disease control rate (DCR), overall survival and safety. We also explored the efficacy of subgroups defined by different gene signatures, which were identified using comprehensive genomic variation profiling (FoundationOne CDx). This study is registered with ClinicalTrials.gov, NCT04034589.Results: From July 9, 2019 to June 20, 2021, 34 patients were enrolled; 19 (55.8%) patients had visceral metastases. Of 14 patients with measurable disease according to RECIST 1.1, seven (50%) achieved objective response. The DCR was 84.6%. Nine of the 34 included patients discontinued treatment because of disease progression, and PFS was immature. Twelve patients had available data of comprehensive genomic variation profiling, and the results showed that six patients had PIK3CA mutation, ten had TP53 mutation, and 11 had ErbB2 overexpression. The most common treatment-related adverse events were diarrhea and fatigue. The incidence of grade 3 or greater diarrhea was 12.1% (4/33) in patients with available safety data. No patient discontinued treatment because of adverse events. Conclusions: The combination of pyrotinib and fulvestrant was convenient and effective with manageable toxicity, which may offer a chemotherapy-free alternative treatment option for patients with HR+/HER2+ metastatic breast cancer.
