Abstract
Over the years, there has been significant interest in PEGylated lipid-based nanocarriers within the drug delivery field. The inevitable interplay between the nanocarriers and plasma protein plays a pivotal role in their in vivo biological fate. Understanding the factors influencing lipid-based nanocarrier and protein corona interactions is of paramount importance in the design and clinical translation of these nanocarriers. Herein, discoid-shaped lipid nanodiscs (sNDs) composed of different phospholipids with varied lipid tails and head groups were fabricated. We investigated the impact of phospholipid components on the interaction between sNDs and serum proteins, particle stability, and biodistribution. The results showed that all of these lipid nanodiscs remained stable over a 15 day storage period, while their stability in the blood serum demonstrated significant differences. The sND composed of POPG exhibited the least stability due to its potent complement activation capability, resulting in rapid blood clearance. Furthermore, a negative correlation between the complement activation capability and serum stability was identified. Pharmacokinetic and biodistribution experiments indicated that phospholipid composition did not influence the capability of sNDs to evade the accelerated blood clearance phenomenon. Complement deposition on the sND was inversely associated with the area under the curve. Additionally, all lipid nanodiscs exhibited dominant adsorption of apolipoprotein. Remarkably, the POPC-based lipid nanodisc displayed a significantly higher deposition of apolipoprotein E, contributing to an obvious brain distribution, which provides a promising tool for brain-targeted drug delivery.

Abstract
Objective: To understand the situation and epidemic characteristics of injury deaths among children aged 5 to 24 years in Jiangsu Province from 2012 to 2021 and the trend of annual changes. Methods: The main injury mortality data of children and adolescents was collected, and the crude and standardized mortality rates of road traffic accidents, drowning, suicide, and accidental falls among children and adolescents over a decade and the annual average percentage of change (AAPC) were calculated. The main injury mortality characteristics and trends of children and adolescents of different age groups and genders were analyzed. Results: The total number of injury deaths among 5 to 24 adolescents in Jiangsu Province was 16 052, with a standardized mortality rate of 9.58/100 000. There was no significant trend in the overall standardized mortality rate of injuries (AAPC=-3.450%, P=0.055). The standardized mortality rate of road traffic injuries among children and adolescents showed a decreasing trend over the past decade, with statistical significance (AAPC=-9.406%, P<0.001). The standardized suicide mortality rate showed an upward trend over the past decade, with statistical significance (AAPC=9.000%, P=0.001). The overall injury mortality rate showed an upward trend with age. Suicide rates in males and females were on the rise and both have statistical significance (AAPC=9.420% and AAPC=9.607%, both P<0.05). The standardized mortality rates of female traffic accidents, drowning, and male traffic accidents showed a decreasing trend and were statistically significant (AAPC for female traffic accidents=-7.364%, AAPC for female drowning=-5.352%, and AAPC for male traffic accidents=-10.242%, all P<0.05). The standardized mortality rate of urban and rural traffic accidents showed a decreasing trend and was statistically significant(AAPC=-7.899% and AAPC=-9.421%, both P<0.001). The standardized suicide mortality rate showed an upward trend and statistical significance (AAPC=11.009% and AAPC=7.528%, both P<0.05). Conclusions: The overall injury situation of children and adolescents in Jiangsu Province improved in the past decade from 2012 to 2021, but the suicide mortality rate was on the rise. It is necessary to focus on the mental health issues of this age group and to strengthen the prevention and control of suicide among children and adolescents, in Jiangsu.

Abstract
Background Primary pulmonary lymphoepithelioma-like carcinoma (PPLELC) is a rare yet aggressive malignancy. This study aims to investigate a deep learning model based on hematological indices, referred to as haematological indices-based signature (HIBS), and propose multivariable predictive models for accurate prognosis prediction and assessment of therapeutic response to immunotherapy in PPLELC. Methods This retrospective study included 117 patients with PPLELC who received immunotherapy and were randomly divided into a training (n=82) and a validation (n=35) cohort. A total of 41 hematological features were extracted from routine laboratory tests and the least absolute shrinkage and selection operator (LASSO) algorithm were utilized to establish the HIBS. Additionally, we developed a nomogram using the HIBS and clinical characteristics through multivariate Cox regression analysis. To evaluate the nomogram's predictive performance, we used calibration curves and calculated the time-dependent area under the curve (AUC). Kaplan-Meier survival analysis was performed to estimate progression-free survival (PFS) in both cohorts. Results The proposed HIBS comprised 14 hematological features and showed that patients who experienced disease progression had significantly higher HIBS scores compared to those who did not progress (P<0.001). Five prognostic factors, including HIBS, tumor-node-metastasis (TNM) stage, presence of bone metastasis and the specific immunotherapy regimen, were found to be independent factors and were used to construct a nomogram, which effectively categorized PPLELC patients into a high-risk and a low-risk group, with patients in the high-risk patients demonstrating worse PFS (7.0 vs. 18.0 months, P<0.001) and lower overall response rates (22.2% vs. 52.7%, P<0.001). The nomogram showed satisfactory discrimination for PFS, with AUC values of 0.837 and 0.855 in the training and validation cohorts, respectively. Conclusions The HIBS-based nomogram could effectively predict the PFS and response of patients with PPLELC regarding immunotherapy and serve as a valuable tool for clinical decision making.

Abstract
Dairy cow behavior carries important health information. Timely and accurate detection of behaviors such as drinking, feeding, lying, and standing is meaningful for monitoring individual cows and herd management. In this study, a model called Res-DenseYOLO is proposed for accurately detecting the individual behavior of dairy cows living in cowsheds. Specifically, a dense module was integrated into the backbone network of YOLOv5 to strengthen feature extraction for actual cowshed environments. A CoordAtt attention mechanism and SioU loss function were added to enhance feature learning and training convergence. Multi-scale detection heads were designed to improve small target detection. The model was trained and tested on 5516 images collected from monitoring videos of a dairy cowshed. The experimental results showed that the performance of Res-DenseYOLO proposed in this paper is better than that of Fast-RCNN, SSD, YOLOv4, YOLOv7, and other detection models in terms of precision, recall, and mAP metrics. Specifically, Res-DenseYOLO achieved 94.7% precision, 91.2% recall, and 96.3% mAP, outperforming the baseline YOLOv5 model by 0.7%, 4.2%, and 3.7%, respectively. This research developed a useful solution for real-time and accurate detection of dairy cow behaviors with video monitoring only, providing valuable behavioral data for animal welfare and production management.

Abstract
The aim of this study is to identify an alternative approach for simulating the in vitro fermentation and quantifying the production of rumen methane and rumen acetic acid during the rumen fermentation process with different total mixed rations. In this experiment, dietary nutrient compositions (neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), and dry matter (DM)) were selected as input parameters to establish three prediction models for rumen fermentation parameters (methane and acetic acid): an artificial neural network model, a genetic algorithm-bp model, and a support vector machine model. The research findings show that the three models had similar simulation results that aligned with the measured data trends (R2 ≥ 0.83). Additionally, the root mean square errors (RMSEs) were ≤1.85 mL/g in the rumen methane model and ≤2.248 mmol/L in the rumen acetic acid model. Finally, this study also demonstrates the models' capacity for generalization through an independent verification experiment, as they effectively predicted outcomes even when significant trial factors were manipulated. These results suggest that machine learning-based in vitro rumen models can serve as a valuable tool for quantifying rumen fermentation parameters, guiding the optimization of dietary structures for dairy cows, rapidly screening methane-reducing feed options, and enhancing feeding efficiency.

Abstract
Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer with a low 5-year survival rate. ANKRD22 is an ankyrin repeat protein capable of promoting tumor progression, and its mechanism in LUAD remains elusive. Our study aims to investigate the mechanisms underlying the involvement of ANKRD22 in the progression of LUAD. The expression of ANKRD22 in LUAD and its enriched pathway were analyzed by bioinformatics analysis. Meanwhile, the correlation between ANKRD22 and the expression of glycolysis-related genes and M2 macrophage marker genes was analyzed. qRT-PCR was used for determination of the expression of ANKRD22, IL-10 and CCL17, CCK-8 for cell viability, and western blot for expression of ANKRD22, LDHA, HK2, PGK1, and PKM2. Immunofluorescence and flow cytometry were utilized to examine the level of CD163, and kits were used to measure the contents of pyruvic acid, lactate, citrate, and malate. Seahorse XF96 analyzer was employed to determine extracellular acidification rate (ECAR) and oxygen consumption rate (OCR). Mitochondrial membrane potential was assessed using the JC-1 probe. Bioinformatics analysis, qRT-PCR, and western blot showed that ANKRD22 was highly expressed in LUAD, which had a positive connection with M2 marker genes. Knockdown of ANKRD22 considerably attenuated the expression of ANKRD22, IL-10, and CCL17 in M2. ANKRD22 overexpression demonstrated the opposite results. Bioinformatics analysis uncovered that ANKRD22 was enriched in the glycolytic pathway and positively correlated with glycolysis-related genes. The knockdown of ANKRD22 substantially attenuated pyruvic acid, lactate, citrate, malate, and ECAR levels and elevated OCR levels in cells. The knockdown of ANKRD22 also reduced mitochondrial membrane potential. Further, it was discovered that glycolysis-related genes had a positive correlation with M2 marker genes. It was revealed by rescue experiments that the usage of 2-DG, a glycolytic inhibitor, remarkably reversed the facilitating effect of overexpression of ANKRD22 on M2 polarization. This study demonstrates that ANKRD22 can facilitate LUAD M2 polarization through glycolysis, and targeting ANKRD22 to inhibit M2 polarization has the potential to be a new strategy for LUAD treatment.

Abstract
Sensitive and accurate biomarker-driven assay guidance has been widely adopted to identify responsive patients for immune checkpoint blockade (ICB) therapy to impede disease progression and extend survival. However, most current assays are invasive, requiring surgical pathology specimens and only informing monochronic information. Here, we report a multiplexed enhanced fluorescence microarray immunoassay (eFMIA) based on a nanostructured gold nanoisland substrate (AuNIS), which macroscopically amplifies near-infrared fluorescence (NIRF) of a structurally symmetric IRDye78 fluorophore by over two orders of magnitude of 202.6-fold. Aided by non-contact piezo-driven micro-dispensing (PDMD), eFMIA simultaneously and semi-quantitatively detected intracellular and secreted programmed death-ligand 1 (PD-L1) and intercellular adhesion molecule-1 (ICAM-1) in human nasopharyngeal carcinoma (NPC) cells. The assay performance was superior to fluorescence immunoassays (FIA) and enzyme-linked immunosorbent assays (ELISA), with lower detection limits. Using eFMIA, we found significantly differential levels of soluble PD-L1 (sPD-L1) and sICAM-1 in the sera of 28 cancer patients, with different clinical outcomes following anti-PD-1 ICB therapy. With a well-characterized mechanism, the high-performance plasmonic multiplexed assay with the composite biomarkers may be a valuable tool to assist clinicians with decision-making and patient stratification to afford predictive ICB therapy responses.

Abstract
Objective Asthma is a major public health problem that affects both children and adults, and its prevalence varies among people with different climatic characteristics and living habits. However, few studies have investigated the prevalence and risk factors for asthma among tropical residents in China. Therefore, this study aims to investigate the correlation between individuals' living environment and daily habits in Hainan Province, and the occurrence of asthma. Methods This cross-sectional study collected data from 1021 participants in three regions of the Hainan Province. A questionnaire derived from the European Community Respiratory Health Survey was used to collect data on demographics, living habits, self-reported asthma, and respiratory system-related symptoms. Logistic regression was used for univariate and multivariate analyses to screen for relative risk factors associated with asthma. Results Among the 1,021 subjects investigated, the prevalence rate of self-reported asthma was 18.6%. Significant risk factors for asthma include hair dyeing, longer living time in Hainan, higher BMI, and living in a damp and musty room. Protective factors included fruit intake, years of higher education, and indoor timing of natural ventilation. Conclusion Higher frequency of hair dyeing, higher body mass index (BMI), longer living in Hainan, lower frequency of fruit intake, fewer years of education, a damp and musty room, and no indoor timing natural ventilation were associated with an increased risk of asthma.

Abstract
OBJECTIVE To investigate the effect of contralateral controlled functional electrical stimulation (CCFES) combined with mirror therapy on motor function and negative mood in stroke patients. METHODS Medical records of 94 stroke patients in Baoji Central Hospital admitted from April 2020 to October 2022 were retrospectively analyzed. Among them, 45 patients receiving routine rehabilitation training combined with mirror therapy were included in a control group, and 49 patients receiving CCFES combined with mirror therapy were in an observation group. Observation indexes included changes in Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS), Hamilton Anxiety Rating Scale (HAMA), Hamilton Depression Rating Scale (HAMD), Stroke Specific Quality of Life Scale (SS-QoL) score, and Barthel Index score before and after treatment. Patients with HAMA score >14 and HAMD score ≥20 after the treatment were included in a negative mood group, and logistics regression was used to analyze the risk factors for negative mood. RESULTS The observation group had a significantly higher overall response rate after treatment compared to the control group. In addition, the observation group exhibited significantly higher scores in the FMA and BBS after treatment, indicating better physical function (P<0.001). Furthermore, the observation group showed lower HAMA and HAMD scores after treatment, suggesting reduced anxiety and depression levels (P<0.001). The quality-of-life scores measured by the SS-QoL and the Barthel Index score were both increased in the observation group after treatment, indicating better overall well-being and functional independence (P<0.001). Logistic regression analysis revealed that age, post-treatment SS-QoL scores, and post-treatment Barthel Index were identified as influencing factors for the onset of adverse emotions in patients (P<0.05). CONCLUSION CCFES plus mirror therapy can effectively ameliorate limb function and lessen anxiety and depression in stroke patients, exerting beneficial effects on rehabilitation.

Abstract
PURPOSE This study was to investigate the biological effect of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 2 (PFKFB2) in colorectal cancer (CRC). METHODS PFKFB2 was selected by metabolism polymerase chain reaction (PCR) array from CRC cells under alkaline culture medium (pH 7.4) and acidic culture medium (pH 6.8). The expression of PFKFB2 mRNA and protein was detected by quantitative real-time PCR and immunohistochemistry in 70 paired fresh and 268 paired paraffin-embedded human CRC tissues, respectively, and then the prognostic value of PFKFB2 was investigated. The effects of PFKFB2 on CRC cells were also verified in vitro, which were through detecting the change of migration, invasion, sphere formation, proliferation, colony formation, and extracellular acidification rate of CRC cells after PFKFB2 knockdown in alkaline culture medium (pH 7.4) and overexpression in acidic culture medium (pH 6.8). RESULTS PFKFB2 expression was downregulated in acidic culture medium (pH 6.8). In addition, we found PFKFB2 expression decreased in human CRC tissues compared with the adjacent normal tissues. Furthermore, the OS and DFS rate of CRC patients with low PFKFB2 expression was significantly shorter than those of patients with high PFKFB2 expression. Multivariate analysis indicated that low PFKFB2 expression was an independent prognostic factor for both OS and DFS in CRC patients. Moreover, the abilities of migration, invasion, spheroidizing ability, proliferation, and colony formation of CRC cells were significantly increased after depletion of PFKFB2 in alkaline culture medium (pH 7.4) and decreased after overexpression of PFKFB2 in acidic culture medium (pH 6.8) in vitro. Epithelial-mesenchymal transition (EMT) pathway was found and verified involved in the PFKFB2-mediated regulation of metastatic function in CRC cells. Further, glycolysis of CRC cells was significantly elevated after knockdown of PFKFB2 in alkaline culture medium (pH 7.4) and decreased after overexpression of PFKFB2 in acidic culture medium (pH 6.8). CONCLUSION PFKFB2 expression is downregulated in CRC tissues and associated with worse survival for CRC patients. PFKFB2 could inhibit metastasis and the malignant progression of CRC cells by suppressing EMT and glycolysis.

Abstract
BACKGROUND Oligoasthenoteratozoospermia (OAT) is one of the most complex aggregators of male gametic problems. However, the genetic etiology of OAT is still largely unknown. OBJECTIVES To reveal the new genetic factors responsible for male infertility owning to OAT and reveal the outcomes of the affected patients from intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS Two infertile men with typical OAT were recruited in 2018 and retrospected a cohort that included 47 patients with OAT from 2013 to 2021. Fifty healthy men with proven fertility served as control subjects. To identify the novel pathogenic variants, whole-exome sequencing and Sanger sequencing were used. In silico analysis revealed the affecting of the variants. Field emission scanning electron microscopy was employed to observe the morphological defects of the spermatozoa. Immunofluorescence was used to analyze the expression and localization of the related protein. CRISPR/Cas9 was used to generate the mouse model. ICSI was used as a treatment for the patients and to assess the effects of the pathogenic variant on fertilization and embryo development. RESULTS We identified a loss-of-function mutation NM_001170574.2:c.823G > T (p.Glu275*) in X-linked TENT5D from two patients with OAT. This variant is highly deleterious and has not been found in the human population. The count of patients' spermatozoa is dramatically decreased and displays multiple morphologic abnormalities with poor motility. Tent5d knockout mice are infertile and exhibit parallel defects. ICSI could rescue the infertility of the Tent5d knockout male mice. Moreover, the proband was treated with ICSI and achieved a successful pregnancy outcome for the first time. Subsequent mutation screening identified no TENT5D mutations among 47 additional patients with OAT and 50 control subjects. CONCLUSION Mutation in TENT5D results in OAT and male infertility, and this terrible situation could be rescued by ICSI.

Abstract
In recent years, olfactory dysfunction has attracted increasingly more attention as a hallmark symptom of neurodegenerative diseases (ND). Deeply understanding the molecular basis underlying the development of the olfactory bulb (OB) will provide important insights for ND studies and treatments. Now, with a genetic knockout mouse model, we show that TRIM67, a new member of the tripartite motif (TRIM) protein family, plays an important role in regulating the proliferation and development of mitral cells in the OB. TRIM67 is abundantly expressed in the mitral cell layer of the OB. The genetic deletion of TRIM67 in mice leads to excessive proliferation of mitral cells in the OB and defects in its synaptic development, resulting in reduced olfactory function in mice. Finally, we show that TRIM67 may achieve its effect on mitral cells by regulating the Semaphorin 7A/Plexin C1 (Sema7A/PlxnC1) signaling pathway.

Abstract
Aluminum salts are by far the most widely used adjuvants for human vaccines, showing acceptable safety and efficacy. Previous studies have shown that each aluminum adjuvant have different charges and morphologies, but whether the manufacturing and production processes affects the physicochemical properties of aluminum adjuvant has not yet been reported. In this study, we explored the physical and chemical properties of different aluminum adjuvants and Hib, sIPV antigens through particle size, zeta potential and morphological characteristics. The adsorption rate and efficacy were also investigated. The results showed that the preparation process had an impact on the physical and chemical properties of aluminum adjuvants, including differences in the particle size,zeta potential and morphological structure. Hib vaccine had larger particle size than sIPV vaccine with different aluminum adjuvants in the process of vaccine preparation. In addition, by measuring the adsorption rate, increasing the concentration of phosphate or Aluminum phosphate (AP) can improve the adsorption rate of Hib, but Aluminium hydroxide (AH) and amorphous aluminum hydroxyphosphate sulfate (AAHS) adjuvants are not affected. In vivo result showed that increasing the adsorption rate of Hib could enhance the Hib-IgG antibody titers. In conclusion, this study provides a reference for the application of adjuvants in vaccines by studying the physicochemical properties and adsorption conditions of different aluminum adjuvants and antigens.

Abstract
Background Alterations in Mitochondrial DNA methylation (MTDM) exist in many tumors, but their role in breast cancer (BC) development remains unclear. Methods We analyzed BC patient data by combining scRNA-seq and bulk sequencing. Weighted co-expression network analysis (WGCNA) of TCGA data identified mitochondrial DNA methylation (MTDM)-associated genes in BC. COX regression and LASSO regression were used to build prognostic models. The biological function of MTDM was assessed using various methods, such as signaling pathway enrichment analysis, copynumber karyotyping analysis, and quantitative analysis of the cell proliferation rate. We also evaluated MTDM-mediated alterations in the immune microenvironment using immune microenvironment, microsatellite instability, mutation, unsupervised clustering, malignant cell subtype differentiation, immune cell subtype differentiation, and cell-communication signature analyses. Finally, we performed cellular experiments to validate the role of the MTDM-associated prognostic gene NCAPD3 in BC. Results In this study, MTDM-associated prognostic models divided BC patients into high/low MTDM groups in TCGA/GEO datasets. The difference in survival time between the two groups was statistically significant (P<0.001). We found that high MTDM status was positively correlated with tumor cell proliferation. We analyzed the immune microenvironment and found that low-MTDM group had higher immune checkpoint gene expression/immune cell infiltration, which could lead to potential benefits from immunotherapy. In contrast, the high MTDM group had higher proliferation rates and levels of CD8+T cell exhaustion, which may be related to the secretion of GDF15 by malignant breast epithelial cells with a high MTDM status. Cellular experiments validated the role of the MTDM-associated prognostic gene NCAPD3 (the gene most positively correlated with epithelial malignant cell proliferation in the model) in BC. Knockdown of NCAPD3 significantly reduced the activity and proliferation of MDA-MB-231 and BCAP-37 cells, and significantly reduced their migration ability of BCAP-37 cell line. Conclusion This study presented a holistic evaluation of the multifaceted roles of MTDM in BC. The analysis of MTDM levels not only enables the prediction of response to immunotherapy but also serves as an accurate prognostic indicator for patients with BC. These insightful discoveries provide novel perspectives on tumor immunity and have the potentially to revolutionize the diagnosis and treatment of BC.

Abstract
PURPOSE In this study, we investigated the effects of mirror therapy (MT) combined with contralaterally controlled functional electrical stimulation (CCFES) on upper limb motor function, activities of daily life, and corticospinal excitability in post-stroke patients. METHODS Sixty post-stroke patients were randomly divided into four groups: CCFES, MT, MT combined with CCFES, and control. All the patients underwent routine rehabilitation. Those in the MT, CCFES, MT combined with CCFES, and control groups received MT, CCFES, MT combined with CCFES, and routine rehabilitation alone, respectively. Upper limb motor function, activities of daily living, and corticospinal excitability were evaluated before and after a 3-week intervention period. RESULTS MT combined with CCFES demonstrated a significantly greater therapeutic effect on motor function of the paretic wrist than CCFES, MT, or routine rehabilitation alone. However, there was no significant difference in the overall motor function of the affected upper limb, activities of daily life, or corticospinal excitability between the MT combined with CCFES group and the other three groups. CONCLUSION MT combined with CCFES may be a potential adjuvant therapy to promote motor function in paretic wrist after stroke.

Abstract
Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

Abstract
Nitrate addition is a biostimulation technique that can improve both the oxidation of acid volatile sulfide (AVS) through autotrophic denitrification and the biodegradation of polycyclic aromatic hydrocarbons (PAHs) via heterotrophic denitrification. However, during the remediation, parts of the dissolved nitrate in the sediment migrates from the sediment to the overlying water, leading to the loss of effective electron acceptor. To overcome this limitation, a combined approached was proposed, which involved nitrocellulose addition and a microbial fuel cell (MFC). Results indicated the nitrate could be slowly released and maintained at a higher concentration over long term. In the combined system, the removal efficiencies of PAHs and AVS were 71.56% and 89.76%, respectively. Furthermore, the voltage attained for the MFC-nitrocellulose treatment was maintained at 146.1 mV on Day 70, which was 5.37 times higher than that of the MFC-calcium nitrate treatment. Sediments with nitrocellulose resulted in lower levels of nitrate and ammonium in the overlying water. Metagenomic results revealed that the combined technology improved the expression of nitrogen-cycling genes. The introduction of MFC inhibited sulfide regeneration during incubation by suppressing the enzyme activity like EC4.4.1.2. The enhanced biostimulation provided potential for in-situ bioremediation utilizing MFC coupled with slow-released nitrate (i.e., nitrocellulose) treatment.

Abstract
Oleanolic acid (OA, (3β)-3-hydroxy-oleanol-12-en-28-oic acid) derivative DKS26 has hypolipidemic, islet and hepatoprotective effects. However, high lipophilicity and low water solubility of DKS26 led to its extremely low oral bioavailability. Herein, lipid-based nanocarriers, including lipid nanodiscs (sND/DKS26) and liposomes (sLip/DKS26), were prepared to carry DKS26 for improved oral absorption. In comparison to free DKS26 (5.81%), the absolute oral bioavailability of both formulations was significantly increased to 29.47% (sND/DKS26) and 37.25% (sLip/DKS26) without detectable toxicity or immunogenicity even after repeated administrations. Both sND/DKS26 and sLip/DKS26 significantly reduced the feeding glucose level and the AUC of OGTT in db/db diabetic mice. Aiding by our newly developed scFv-based nanocarrier separation methods, we nearly did not detect intact nanocarriers in the blood circulation after oral administration, suggesting that both lipid-based formulations were unable to penetrate the intestinal epithelium as expected. They enhanced DKS26 absorption mainly by improving intestinal cells uptake and rapid intracellular release of the payload. Since pre-existing anti-PEG has been widely detected in human, the present oral absorption pathway of both lipid-based nanocarriers successfully avoided unfavorable immunological responses after interaction with anti-PEG antibodies. The application of lipid-based nanocarriers paves an efficient and safe avenue for the clinical translation and application of poorly soluble therapeutics derived from traditional Chinese medicine.

Abstract
Based on the characteristics of typical C9 + aromatics in naphtha fractions, the effects of key process parameters and heavy aromatic composition on product distribution of fluid catalytic cracking (FCC) of heavy aromatics (HAs) were investigated. The results show that catalysts with large pore size and strong acid sites are favorable for the conversion of HAs to benzene-toluene-xylene (BTX) at higher reaction temperatures and moderate catalyst-oil ratios (C/O). With a Y zeolite-based catalyst which was hydrothermally pretreated for 4 h, the conversion of Feed 1 at 600 °C and C/O of 10 may reach 64.93%. Meanwhile, the yield and selectivity of BTX are 34.80 and 53.61%, respectively. The proportion of BTX can be adjusted within a certain range. The HAs from different sources show high conversion and good BTX selectivity, which provides strong support for the technological development of HAs to light aromatics in FCC operation.

Abstract
OBJECTIVE To compare the consistency between superb microvascular imaging (SMI) and contrast-enhanced ultrasound (CEUS) for the detection of neovascularization in carotid plaques of different thicknesses and to evaluate the applied value of these two methods for detecting neovascularization in carotid plaques in the clinic. METHODS A total of 45 patients with carotid artery plaques who were diagnosed in our hospital involving 76 hypoechoic plaques with a thickness ≥2.0 mm were selected. According to thickness, the plaques were divided into three groups: 2.0-2.5 mm, 2.5-3.0 mm and ≥3.0 mm. Each group underwent both SMI and CEUS, and two experienced sonographers (A and B) analyzed the ultrasound images to evaluate the neovascularization of carotid plaques. The amount of the neovascular signal was assessed using a semi-quantitative grading scale (vascularity grade: grade 0-3). SMI and CEUS were graded respectively according to the visual methods as follows: grade 0: no blood flow signal/enhancement within plaques; grade 1: a few blood flow signals/enhancement within plaques; grade 2: medium blood flow signals/enhancement within plaques; and grade 3: extensive blood flow signals/enhancement within plaques. Kappa consistency test was used to analyze the consistency of the grade of neovascularization in plaques between SMI with CEUS. Gamma rank correlation analysis was used to examine the correlation between neovascularization grade by SMI and CEUS in plaque and plaque thickness. RESULTS Of these patients, 14 had unilateral plaques and 31 had bilateral plaques. The two sonographers were highly consistent in terms of applying SMI and CEUS methods for diagnosing neovascularization in carotid plaques (Kappa values were 0.736 and 0.680>0). Consistency was found between SMI and CEUS by sonographers (sonographer A: Kappa=0.823; sonographer B: Kappa=0.842) in evaluating the neovascular grade in the carotid plaques. SMI and CEUS grades were positively correlated with plaque thickness (sonographer A: γ = 0.735 and 0.772; sonographer B: γ = 0.805 and 0.798). CONCLUSION Neovascularization in carotid plaques was successfully detected by SMI in a manner that concurred well with CEUS results. Our data indicate that both CEUS and SMI have high diagnostic value for assessing the neovascularization of plaques.

Abstract
Melanoma differentiation-associated gene 9 (MDA-9) is a small adaptor protein with tandem PDZ domains that promotes tumor progression and metastasis in various human cancers. However, it is difficult to develop drug-like small molecules with high affinity due to the narrow groove of the PDZ domains of MDA-9. Herein, we identified four novel hits targeting the PDZ1 and PDZ2 domains of MDA-9, namely PI1A, PI1B, PI2A, and PI2B, using a protein-observed nuclear magnetic resonance (NMR) fragment screening method. We also solved the crystal structure of the MDA-9 PDZ1 domain in complex with PI1B and characterized the binding poses of PDZ1-PI1A and PDZ2-PI2A, guided by transferred paramagnetic relaxation enhancement. The protein-ligand interaction modes were then cross-validated by the mutagenesis of the MDA-9 PDZ domains. Competitive fluorescence polarization experiments demonstrated that PI1A and PI2A blocked the binding of natural substrates to the PDZ1 and PDZ2 domains, respectively. Furthermore, these inhibitors exhibited low cellular toxicity, but suppressed the migration of MDA-MB-231 breast carcinoma cells, which recapitulated the phenotype of MDA-9 knockdown. Our work has paved the way for the development of potent inhibitors using structure-guided fragment ligation in the future.

Abstract
BACKGROUND Asthenozoospermia is a major factor contributing to male infertility. The mitochondrial sheath (MS), an important organelle in the midpiece of spermatozoa, is crucial to sperm motility. ARMC12 is a mitochondrial peripheral membrane protein. Deletion of Armc12 impairs the arrangement of MS and causes infertility in mice. However, the role of ARMC12 in human asthenozoospermia remains unknown. OBJECTIVE To study the genetic defects in patients with asthenozoospermia. METHODS A total of 125 patients with asthenozoospermia and 120 men with proven fertility were recruited. Whole-exome sequencing and Sanger sequencing were performed for genetic analysis. Papanicolaou staining, HE staining, immunofluorescent staining, transmission electron microscopy and field emission scanning electron microscopy were employed to observe the morphological and structural defects of the spermatozoa and testes. Armc12-knockout mice were generated using the CRISPR-Cas9 system. Intracytoplasmic sperm injection was used to treat the patients. RESULTS Biallelic ARMC12 mutations were identified in three patients, including homozygous mutations in two siblings from a consanguineous family and compound heterozygous mutations in one sporadic patient. ARMC12 is mainly expressed in the midpiece of elongated and late spermatids in the human testis. The patients' spermatozoa displayed multiple midpiece defects, including absent MS and central pair, scattered or forked axoneme and incomplete plasma membrane. Spermatozoa from Armc12-/- mice showed parallel defects in the midpiece. Moreover, two patients were treated with intracytoplasmic sperm injection and achieved good outcomes. CONCLUSION Our findings prove for the first time that defects in ARMC12 cause asthenozoospermia and multiple midpiece defects in humans.

Abstract
352 Background: CMG901, an anti-claudin 18.2 (CLDN18.2) antibody-drug conjugate, has demonstrated potent preclinical anti-cancer activity through monomethyl auristatin E (MMAE)-mediated cytotoxicity with bystander killing, antibody-dependent cellular cytotoxicity, and complement-dependent cytotoxicity. Methods: This Phase 1a trial uses a modified 3+3 dose-escalation design to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary anti-tumor activity in subjects (ages 18-75 years) with advanced gastric, gastroesophageal junction (GEJ), pancreatic cancers, and other solid tumors. Eligible subjects are refractory and/or intolerant to standard therapies. CLDN18.2 expression was not required for study entry, but was retrospectively tested by the central lab. CMG901 was administered intravenously on Day 1 in 3-week (Q3W) cycle at doses of 0.3, 0.6, 1.2, 1.8, 2.2, 2.6, 3.0, and 3.4 mg/kg. Primary endpoints include safety and tolerability. Major efficacy endpoints include objective response rate (ORR) and disease control rate (DCR) based on RECIST v1.1. Pharmacokinetics (PK) and immunogenicity are also assessed. Results: As of August 4, 2022, 27 subjects (13 gastric/GEJ cancer and 14 pancreatic cancer patients) received CMG901 at dose levels up to 3.4 mg/kg. The median prior lines of systemic therapy were 2 (range: 1 to 5). Drug-related grade ≥3 adverse events (AEs) occurred in 3/27 (11.1%) patients. No drug-related grade 4 or 5 AEs were reported. MTD was not reached. In CLDN18.2-positive gastric/GEJ cancer patients, ORR and DCR were 75.0% and 100%, respectively, with ORR of 100% in the 2.6, 3.0, and 3.4 mg/kg Q3W dose cohorts. Median progression-free survival (mPFS) and median overall survival (mOS) were not reached yet. PK data showed that patients had low systemic exposure to unconjugated MMAE. Subsequent results will be presented. Conclusions: CMG901 was well-tolerated with preliminary promising clinical efficacy in patients with CLDN18.2-positive gastric/GEJ cancer. The Phase 1b dose-expansion trial in gastric/GEJ adenocarcinoma, pancreatic cancer, and other solid tumors is rapidly enrolling, with multiple pivotal (Phases 2 and 3) trials planned. Clinical trial information: NCT04805307 . [Table: see text]

Abstract
As one of the leading cases of acute liver failure triggered by excessive Acetaminophen (APAP), breakdown of the antioxidant system, inflammatory response, and inescapable apoptosis following overaccumulation of reactive oxygen species (ROS) play crucial roles in the mechanisms of APAP-induced liver injury (AILI). Therefore, cutting off ROS overproduction at the source is considered promising. Here, manganese Prussian blue nanozymes (MPBZs) with superior antioxidant enzyme-like activity are prepared as an effective strategy for hepatocyte protection, in which MPBZs accumulated in the liver show anti-oxidation properties by scavenging superfluous ROS. Importantly, in addition to alleviating oxidative stress, bioactive MPBZs with abundant variable valence states as a natural antioxidant enzymes mediated the responses of multi-biological signaling pathways in vitro and in vivo, including Nrf2-Keap1, NF-κB, and mitochondrial-induced apoptosis signaling pathways, enhancing tolerance for imminent AILI. Taking nanomedicine, hepatology, and catalytic chemistry into consideration, the revealed superior performance of AILI prevention suggests that MPBZ-based nano-detoxification therapy may offer an effective alternative against AILI.

Abstract
Thallium (Tl) is a rare and extremely toxic metal whose toxicity is significantly higher than cadmium (Cd), lead (Pb) and antimony (Sb). The extensive utilization of Tl-bearing minerals, such as mining activities, has led to severe Tl pollution in a variety of natural settings, while little is known to date about its effect on the microbial diversity in paddy soils. Also, the geochemical behavior of Tl in the periodical alterations between dry and wet conditions of paddy soils remains largely unknown. Herein, the sequential extraction method and 16S rRNA gene sequence analysis were adopted to analyze Tl's migration and transformation behavior and the microbial diversity in the paddy soils with different pollution levels. The results indicated that Tl was mainly concentrated in reducible fraction, which is different from other types of soils, and may be closely attributed to the abundance of Fe-Mn (hydr)oxides in the paddy rhizospheric soils. Further analysis revealed that pH, total S, Pb, Sb, Tl and Cd were the dominant environmental factors, and the enrichment level of these potentially toxic metal(loid)s (PTMs) exerted obvious impacts on the diversity and abundance of microorganism in the rhizospheric soils, and regulating microbial community. The geochemical fractionation of Tl was closely correlated to soil microorganisms such as Fe reducing bacteria (Geothrix) and sulfate reducing bacteria (Anaerolinea), playing a critical role in Tl geochemical cycle through redox reaction. Hence, further study on microorganisms of paddy rhizospheric soils is of great significance to the countermeasures for remediating Tl-polluted paddy fields and protect the health of residents.

Abstract
Ferric citrate (FC) has been used as an iron fortifier and nutritional supplement, which is reported to induce colitis in rats, however the underlying mechanism remains to be elucidated. We performed a 16-week study of FC in male healthy C57BL/6 mice (nine-month-old) with oral administration of Ctr (0.9 % NaCl), 1.25 % FC (71 mg/kg/bw), 2.5 % FC (143 mg/kg/bw) and 5 % FC (286 mg/kg/bw). FC-exposure resulted in colon iron accumulation, histological alteration and reduce antioxidant enzyme activities, such as glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC), together with enhanced lipid peroxidation level, including malondialdehyde (MDA) level and 4-Hydroxynonenal (4-HNE) protein expression. Exposure to FC was associated with upregulated levels of the interleukin (IL)- 6, IL-1β, IL-18, IL-8 and tumor necrosis factor α (TNF-α), while down-regulated levels of IL-4 and IL-10. Exposure to FC was positively associated with the mRNA and protein expressions of cysteine-aspartic proteases (Caspase)- 9, Caspase-3, Bcl-2-associated X protein (Bax), while negatively associated with B-cell lymphoma 2 (Bcl2) in mitochondrial apoptosis signaling pathway. FC-exposure changed the diversity and composition of gut microbes. Additionally, the serum lipopolysaccharide (LPS) contents increased in FC-exposed groups when compared with the control group, while the expression of colonic tight junction proteins (TJPs), such as Claudin-1 and Occludin were decreased. These findings indicate that the colonic mucosal injury induced by FC-exposure are associated with oxidative stress generation, inflammation response and cell apoptosis, as well as the changes in gut microbes diversity and composition.

Abstract
Introduction Ormosia henryi is a rare and endangered plant growing in southern China. Somatic embryo culture is an effective measure for the rapid propagation of O. henryi. It has not been reported how regulatory genes induce somatic embryogenesis by regulating endogenous hormone changes during the process of somatic embryogenesis in O. henryi. Methods In this study, we analysed the endogenous hormone levels and transcriptome data of nonembryogenic callus (NEC), embryogenic callus (EC), globular embryo (GE) and cotyledon embryo (CE) in O. henryi. Results The results showed that the indole-3-acetic acid (IAA) content was higher and the cytokinins (CKs) content was lower in EC than in NEC, and the gibberellins (GAs) and abscisic acid (ABA) contents were significantly higher in NEC than in EC. The contents of IAA, CKs, GAs and ABA increased significantly with EC development. The expression patterns of differentially expressed genes (DEGs) involved in the biosynthesis and signal transduction of auxin (AUX) (YUCCA and SAUR), CKs (B-ARR), GAs (GA3ox, GA20ox, GID1 and DELLA) and ABA (ZEP, ABA2, AAO3, CYP97A3, PYL and ABF) were consistent with the levels of endogenous hormones during somatic embryogenesis (SE). In this study, 316 different transcription factors (TFs) regulating phytohormones were detected during SE. AUX/IAA were downregulated in the process of EC formation and GE differentiation into CE, but other TFs were upregulated and downregulated. Conclusion Therefore, we believe that relatively high IAA content and low CKs, GAs and ABA contents contribute to EC formation. The differential expression of AUX, CKs, GAs and ABA biosynthesis and signal transduction genes affected the endogenous hormone levels at different stages of SE in O. henryi. The downregulated expression of AUX/IAA inhibited NEC induction, promoted EC formation and GE differentiation into CE.

Abstract
The DTacP-sIPV-Hib combination vaccine can replace the single-component acellular pertussis, diphtheria, tetanus, polio, and Haemophilus influenzae type B vaccines. In this study, we evaluated the safety and immunogenicity of a newly developed DTacP-sIPV-Hib combination vaccine in animal models. We used 40 mice and 46 cynomolgus monkeys to evaluate acute and long-term toxicity. Thirty-six guinea pigs were used for sensitization assessment. For immunogenicity assessment, 50 NIH mice and 50 rats were equally randomized to receive 3 doses of 3 different batches of the tested vaccine at an interval of 21 d, or physiological saline solution (0.5 mL). Orbital blood was collected at an interval of 21 d post inoculation to detect related antibody titers or neutralizing antibody titers against poliovirus. Gross autopsy and histopathological examination revealed no abnormal toxicity or irritation in mice and cynomolgus monkeys. Sensitization assessment in guinea pigs indicated the lack of evident allergic symptoms in the high- and low-dose vaccine groups within 30 min after repeated stimulation. The DTacP-sIPV-Hib combination vaccine induced significant immune responses in mice, rats, and cynomolgus monkeys, with 100% seroconversion rates after 3 doses. The DTacP-sIPV-Hib combination vaccine is safe and immunogenic in animal models. Three doses of the vaccine elicited satisfactory antibody responses in mice, rats, and cynomolgus monkeys.

Abstract
BACKGROUND Timely diagnosis and treatment are crucial for reducing HIV transmission;therefore, estimating the time from HIV infection to antiretroviral therapy (ART) initiation becomes particularly important for people living with HIV. METHODS We used a well-characterised CD4 depletion model to estimate the time from HIV infection to initiation of ART and the rate of delayed HIV diagnosis (infection to diagnosis >1year) and treatment initiation (diagnosis to treatment >1year), based on HIV notification data for adults (aged ≥18years) in Xi'an city, China, during 2008-19. RESULTS Overall, 7402 reported HIV diagnoses were included. We estimated more than two-thirds of HIV infections remained undiagnosed (66.1%, 9489/14 345). The estimated proportion of HIV diagnoses that were delayed (>1year) was 80.3% (5941/7402) during 2008-19, and it increased from 72.7% (32/44) in 2008 to 83.5% (908/1088) in 2019. In contrast, the proportion of cases with delayed treatment (>1year) was 13.1% (971/7402) during 2008-19, and it reduced from 75.0% (33/44) in 2008 to 1.5% (16/1088) in 2019. The estimated median time from HIV infection to diagnosis increased from 5.05 (IQR, 0.27-8.15) years to 5.81 (IQR, 2.31-10.28) years, whereas the time from diagnosis to ART initiation reduced from 3.06 (IQR, 1.01-5.20) years in 2008 to 0.07 (IQR, 0.04-0.12) year in 2019. CONCLUSIONS Early treatment after diagnosis has significantly improved, but timely diagnosis of HIV infections may still require further improvement. The estimated proportion of undiagnosed HIV cases remains high in 2019 in Xi'an city and is likely to impede effective control.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Fat accumulation "sensitizes" the liver to insult and leads to nonalcoholic steatohepatitis (NASH). G protein-coupled receptor 35 (GPR35) is involved in metabolic stresses, but its role in NAFLD is unknown. We report that hepatocyte GPR35 mitigates NASH by regulating hepatic cholesterol homeostasis. Specifically, we found that GPR35 overexpression in hepatocytes protected against high-fat/cholesterol/fructose (HFCF) diet-induced steatohepatitis, whereas loss of GPR35 had the opposite effect. Administration of the GPR35 agonist kynurenic acid (Kyna) suppressed HFCF diet-induced steatohepatitis in mice. Kyna/GPR35 induced expression of StAR-related lipid transfer protein 4 (STARD4) through the ERK1/2 signaling pathway, ultimately resulting in hepatic cholesterol esterification and bile acid synthesis (BAS). The overexpression of STARD4 increased the expression of the BAS rate-limiting enzymes cytochrome P450 family 7 subfamily A member 1 (CYP7A1) and CYP8B1, promoting the conversion of cholesterol to bile acid. The protective effect induced by GPR35 overexpression in hepatocytes disappeared in hepatocyte STARD4-knockdown mice. STARD4 overexpression in hepatocytes reversed the aggravation of HFCF diet-induced steatohepatitis caused by the loss of GPR35 expression in hepatocytes in mice. Our findings indicate that the GPR35-STARD4 axis is a promising therapeutic target for NAFLD.

Abstract
BACKGROUND Tertiary lymphoid structures (TLSs) play key roles in tumour adaptive immunity. However, the prognostic value and molecular properties of TLSs in oesophageal squamous cell carcinoma (ESCC) patients have not been studied. METHODS The prognostic values of the presence and maturation status of tumour-associated TLSs were determined in 394 and 256 ESCC patients from Sun Yat-sen University Cancer Center (Centre A) and the Cancer Hospital of Shantou University Medical College (Centre B), respectively. A deep-learning (DL) TLS classifier was established with haematoxylin and eosin (H&E)-stained slides using an inception-resnet-v2 neural network. Digital spatial profiling was performed to determine the cellular and molecular properties of TLSs in ESCC tissues. RESULTS TLSs were observed in 73.1% of ESCCs from Centre A via pathological examination of H&E-stained primary tumour slides, among which 42.9% were TLS-mature and 30.2% were TLS-immature tumours. The established DL TLS classifier yielded favourable sensitivities and specificities for patient TLS identification and maturation evaluation, with which 55.1%, 39.5% and 5.5% of ESCCs from Centre B were identified as TLS-mature, TLS-immature and TLS-negative tumours. Multivariate analyses proved that the presence of mature TLSs was an independent prognostic factor in both the Centre A and Centre B cohorts (p < .05). Increased proportions of proliferative B, plasma and CD4+ T helper (Th) cells and increased B memory and Th17 signatures were observed in mature TLSs compared to immature ones. Intratumoural CD8+ T infiltration was increased in TLS-mature ESCC tissues compared to mature TLS-absent tissues. The combination of mature TLS presence and high CD8+ T infiltration was associated with the best survival in ESCC patients. CONCLUSIONS Mature TLSs improve the prognosis of ESCC patients who underwent complete resection. The use of the DL TLS classifier would facilitate precise and efficient evaluation of TLS maturation status and offer a novel probability of ESCC treatment individualization.

Abstract
The rise in nosocomial infections caused by multidrug-resistant pathogens is a major public health concern. Patients taking immunosuppressants or chemotherapeutics are naturally more susceptible to infections. Thus, strategies for protecting immunodeficient individuals from infections are of great importance. Here, we investigate the effectiveness of a biomimetic nanotoxoid vaccine in defending animals with immunodeficiency against Pseudomonas aeruginosa. The nanotoxoids use a macrophage membrane coating to sequester and safely present bacterial virulence factors that would otherwise be too toxic to administer. Vaccination with the nanoformulation results in rapid and long-lasting immunity, protecting against lethal infections despite severe immunodeficiency. The nanovaccine can be administered through multiple routes and is effective in both pneumonia and septicemia models of infection. Mechanistically, protection is mediated by neutrophils and pathogen-specific antibodies. Overall, nanotoxoid vaccination is an attractive strategy to protect vulnerable patients and could help to mitigate the threat posed by antibiotic-resistant superbugs.

Abstract
Recombinant adeno-associated virus (AAV) is a promising delivery vehicle for in vivo gene therapy and has been widely used in >200 clinical trials globally. There are already several approved gene therapy products, e.g., Luxturna and Zolgensma, highlighting the remarkable potential of AAV delivery. In the past, AAV has been seen as a relatively non-immunogenic vector associated with low risk of toxicity. However, an increasing number of recent studies indicate that immune responses against AAV and transgene products could be the bottleneck of AAV gene therapy. In clinical studies, pre-existing antibodies against AAV capsids exclude many patients from receiving the treatment as there is high prevalence of antibodies among humans. Moreover, immune response could lead to loss of efficacy over time and severe toxicity, manifested as liver enzyme elevations, kidney injury, and thrombocytopenia, resulting in deaths of non-human primates and patients. Therefore, extensive efforts have been attempted to address these issues, including capsid engineering, plasmapheresis, IgG proteases, CpG depletion, empty capsid decoy, exosome encapsulation, capsid variant switch, induction of regulatory T cells, and immunosuppressants. This review will discuss these methods in detail and highlight important milestones along the way.

Abstract
In mammals, the growth and maturation of oocytes within growing follicles largely depends on ovarian granulosa cells (GCs) in response to gonadotropin stimulation. Many signals have been shown to regulate GC proliferation and apoptosis. However, whether the tyrosine phosphatase SHP2 is involved remains unclear. In this study, we identified the crucial roles of SHP2 in modulating GC proliferation and apoptosis. The production of both mature oocytes and pups was increased in mice with Shp2 specifically deleted in ovarian GCs via Fshr-Cre. Shp2 deletion simultaneously promoted GC proliferation and inhibited GC apoptosis. Furthermore, Shp2 deficiency promoted, while Shp2 overexpression inhibited, the proliferation of cultured primary mouse ovarian GCs and the human ovarian granulosa-like tumor cell line KGN in vitro. Shp2 deficiency promoted follicule-stimulating hormone (FSH)-activated phosphorylation of AKT in vivo. SHP2 deficiency reversed the inhibitory effect of hydrogen peroxide (H2O2) on AKT activation in KGN cells. H2O2 treatment promoted the interaction between SHP2 and the p85 subunit of PI3K in KGN cells. Therefore, SHP2 in GCs may act as a negative modulator to balance follicular development by suppressing PI3K/AKT signaling. The novel function of SHP2 in modulating proliferation and apoptosis of GCs provides a potential therapeutic target for the clinical treatment of follicle developmental dysfunction.

Abstract
Folic acid (FA) is one of the most widely utilized small-molecule ligands for cancer targeted drug delivery. Natural IgM was recently found to avidly absorb on the surface of FA-functionalized liposomes (FA-sLip), negatively regulating the in vivo performance by efficiently activating complement. Herein, FA-functionalized lipodiscs (FA-Disc) were constructed to successfully circumvent IgM-mediated opsonization and retained binding activity with folate receptors in vivo. The FA moiety along with the bound IgM was restricted to the highly curved rim of lipodiscs, leading to IgM incapability of presenting the membrane-bound conformation to trigger complement activation. The C1q docking, C3 binding, and C5a release were blocked and accelerated blood clearance phenomenon was mitigated of FA-Disc. FA-Disc retained folate binding activity and could effectively target folate receptor positive tumors in vivo. The present study provides a useful solution to avoid the negative regulation by IgM and achieve FA-enabled targeting by exploring disc-shaped nanocarriers.

Abstract
Objective: To compare the accuracy of the centerline extracted based on CT 3D reconstruction and conventional CT 3D reconstruction in measuring the length and degree of laryngotracheal stenosis. Methods: A retrospective analysis was performed on 35 patients with laryngotracheal stenosis (including 19 cases without tracheotomy and 16 cases with tracheotomy) treated in the Department of Otorhinolaryngology Head and Neck Surgery of the First Affiliated Hospital of Guangxi Medical University from March 2006 to March 2016, including 20 males and 15 females, whose ages ranged from 1 to 73 years, with a median age of 40.5 years. And CT data of 20 normal subjects were included in the same period, including 10 males and 10 females, whose ages ranged from 20 to 63 years, with a median age of 37.0 years. The continuous cross-sectional area of the airway perpendicular to the centerline was obtained by Mimics software. The area was compared with the discontinuous cross-sectional areas reconstructed by conventional CT 3D reconstruction software advantage workstation, also the length of cervical trachea, the length of stenosis, and the minimum airway area were compared. Multi-factor linear stepwise regression method was used to analyze the factors influencing the measuring difference between the two methods. Three patients with laryngotracheal stenosis were selected, and the measured stenosis length was compared with the surgical specimens to evaluate the accuracy of the two methods. SPSS 26.0 software was used for statistical analysis. Results: In normal people, the areas of thyroid cartilage notch, glottis, inferio thyroid cartilage margin, inferio cricoid cartilage margin, and suprasternal notch planes measured by Mimics centerline method were smaller than those measured by conventional CT 3D reconstruction (t thyroid cartilage notch=4.685, tglottis=3.791, tlower thyroid cartilage margin=5.621, tlower cricoid cartilage margin=6.312, tsuprasternal notch plane=6.436, P<0.05). And the airway length measured by Mimics centerline method from the inferior thyroid cartilage to the superior sternal notch was longer (t=9.79, P<0.001). In laryngotracheal stenosis, in the non-tracheotomy group, the minimum airway area measured by Mimics centerline method was smaller and the stenosis length was longer than those measured by the conventional CT 3D reconstruction, and the difference was statistically significant (tminimum airway area=2.562, tstenosis length=5.240, P<0.05). In the tracheotomy group, the stenosis length measured by Mimics centerline method was longer than that measured by conventional CT 3D reconstruction, and the difference was statistically significant (tstenosis length=2.854, P<0.05). Multi-factor linear regression analysis showed that different CT thickness had a statistically significant effect on the difference in the length of stenosis measured by the two methods (b=-5.370, t=-3.306, P=0.004), and different tracheal forward angle had a statistically significant effect on the difference in the minimum airway area measured by the two methods (b=-0.419, t=-2.208, P=0.04). The difference between the measured length of the Mimics centerline method and the intraoperative specimens was less than 0.5 mm. Conclusion: The centerline extracted based on CT 3D reconstruction can precisely reflect the laryngotracheal morphology and measure laryngotracheal stenosis more accurately.

Abstract
Obesity is considered as a major cause for the development and progress of non-alcoholic fatty liver disease (NAFLD), which is one of the most prevalent chronic liver diseases worldwide. However, molecular mechanisms that implicate in obesity-driven pathophysiology of NAFLD are not well defined. Here, we report a tripartite motif (TRIM) protein family member—TRIM67—that is hardly expressed in liver but is inducible on obese conditions. Enhanced expression of TRIM67 activates hepatic inflammation to disturb lipid metabolic homeostasis and promote the progress of NAFLD induced by obesity, while the deficiency in TRIM67 is protective against these pathophysiological processes. Finally, we show that the important transcription coactivator PGC-1α implicates in the response of hepatic TRIM67 to obesity.

Abstract
Fibrotic diseases remain a substantial health burden with few therapeutic approaches. A hallmark of fibrosis is the aberrant activation and accumulation of myofibroblasts, which is caused by excessive profibrotic cytokines. Conventional anticytokine therapies fail to undergo clinical trials, as simply blocking a single or several antifibrotic cytokines cannot abrogate the profibrotic microenvironment. Here, biomimetic nanoparticles based on autologous skin fibroblasts are customized as decoys to neutralize multiple fibroblast-targeted cytokines. By fusing the skin fibroblast membrane onto poly(lactic-co-glycolic) acid cores, these nanoparticles, termed fibroblast membrane-camouflaged nanoparticles (FNPs), are shown to effectively scavenge various profibrotic cytokines, including transforming growth factor-β, interleukin (IL)-11, IL-13, and IL-17, thereby modulating the profibrotic microenvironment. FNPs are sequentially prepared into multiple formulations for different administration routines. As a proof-of-concept, in three independent animal models with various organ fibrosis (lung fibrosis, liver fibrosis, and heart fibrosis), FNPs effectively reduce the accumulation of myofibroblasts, and the formation of fibrotic tissue, concomitantly restoring organ function and indicating that FNPs are a potential broad-spectrum therapy for fibrosis management.

Abstract
Abstract
Background: Anti-cytotoxic T lymphocyte antigen 4 (CTLA-4) antibody may enhance the efficacy of programmed cell death 1 (PD-1) inhibitor. QL1706 is a novel dual immune checkpoint blockade containing a mixture of anti-PD-1 IgG4 and anti-CTLA4 IgG1 antibodies produced by a single cell line. Here we reported the pooled data of the phase 1a/b trial.
Methods: In the phase 1a dose escalation and expansion study (NCT04296994), dose escalation involved six levels (0.3, 1.0, 3.0, 5.0, 7.5, and 10.0 mg/kg, intravenously q3w) using an accelerated 3+3 design. The dose expansion cohorts received selected doses. In phase 1b (NCT05171790), patients with advanced solid tumors were given intravenous QL1706 5.0 mg/kg q3w according to the data in phase 1a. The primary objectives were to define the safety, tolerability, and recommended phase 2 dose (RP2D) of QL1706 in phase 1a, and to evaluate the preliminary efficacy in phase 1b.
Results: As of Sept 30, 2021, totally 518 patients with multiple types of advanced cancer (99 in phase 1a and 419 in phase 1b) were enrolled, including lung cancer (175 [33.8%]), nasopharyngeal cancer (134 [25.9%]), cervical cancer (58 [11.2%]), liver cancer (34 [6.6%]), colorectal cancer (27 [5.2%]), and kidney cancer (18 [3.5%]), etc. 494 [95.4%] were previously treated, and 182 (35.1%) received previous immunotherapy. Two patients at 10 mg/kg suffered dose-limiting toxicity. The RP2D of QL1706 was defined as 5.0 mg/kg. After a median follow-up of 6.7 months, treatment-related adverse events (TRAEs) were observed in 374 patients (72.2%). 70 (13.5%) experienced grade ≥3 TRAEs. The most common TRAEs were rash (91 [17.6%]), pruritus (65 [12.5%]), hypothyroidism (60 [11.6%]), AST increased (48 [9.3%]), and hyperthyroidism (46 [8.9%]). The TRAEs that led to drug interruption and drug discontinuation were observed in 67 (12.9%) and 31 patients (6.0%), respectively. The immune-related TRAEs and treatment-related serious adverse events were observed in 223 (43.1%) and 59 patients (11.4%), respectively. 79 (16.9%) patients had a confirmed objective response, 237 (50.6%) patients had a confirmed disease control.
Conclusion: QL1706 had a manageable safety profile. QL1706 still showed promising anti-tumor activity although over one-third of the patients received prior immunotherapy. These results supported further investigation of QL1706 for advanced solid tumors.

Abstract
BACKGROUND Phoebe bournei (P. bournei) is an important and endemic wood species in China. However, the plantation, nursing, and preservation of P. bournei are often affected by light. To investigate its physiological changes and molecular mechanism of low light tolerance, two-year-old P. bournei seedlings were subjected to different shading conditions. With the increase of light intensity in the shade, the leaf color of P. bournei seedlings became darkened, the aboveground/underground biomass significantly increased, the content of chlorophyll increased and the net photosynthetic rate significantly increased. RESULTS de novo transcriptome analysis showed that 724 and 3,248 genes were differentially expressed due to low light intensity at T1 (35% light exposure) and T2 (10% light exposure), respectively, when compared to the controls. Furthermore, the differentially expressed genes (DEGs) were implicated in photosynthesis, nitrogen metabolism, plant hormone signal transduction, biosynthesis of secondary metabolites, and protein processing in the endoplasmic reticulum by functional enrichment analysis. Moreover, the expression of HSP, CAB, HEMA1, GSA, DVR, MYB, bHLH, PORA, CAO, GLK, and photosystem I and II complex-related genes significantly increased after low light exposure at T2 and T1. CONCLUSIONS The present study suggests that the rapid growth of P. bournei seedlings under shading conditions may be the result of the accelerated expression of genes related to photosynthesis and chlorophyll biosynthesis, which enable plants to maintain a high photosynthesis rate even under low light conditions.

Abstract
Question What is the safety and antitumor activity of MRG003 in patients with advanced solid tumors? Findings In this phase 1 clinical trial of 61 patients with advanced or metastatic solid tumors, treatment with MRG003 exhibited manageable safety and showed encouraging antitumor activity in squamous cell carcinomas of the head and neck and nasopharyngeal carcinoma, with a confirmed objective response rates of 40% and 44%, respectively. Meaning The study findings suggest the safety of treatment with MRG003 and an acceptable tolerance in most patients with epidermal growth factor receptor–expressing solid tumors, as well as encouraging antitumor activity in patients with squamous cell carcinomas of the head and neck and nasopharyngeal carcinoma. Importance The antibody drug conjugate drug MRG003 comprises an anti–epidermal growth factor receptor (EGFR) humanized immunoglobulin G1 monoclonal antibody that is conjugated with monomethyl auristatin E via a valine-citrulline linker. There is currently insufficient evidence of this drug's safety and efficacy. Objective To evaluate the safety and maximum tolerated dose of MRG003 in a phase 1a study and investigate the preliminary antitumor activity in EGFR-expressing patients in a phase 1b study. Design, Setting, and Participants This nonrandomized open-label, single-arm, phase 1, multicenter study of solid tumors was divided into 2 parts, phase 1a dose escalation and phase 1b dose expansion. Patients with advanced or metastatic solid tumors who had failed outcomes from or were not able to receive standard treatment were enrolled in phase 1a without EGFR prescreening. Phase 1b recruited EGFR-positive patients with refractory advanced squamous cell carcinomas of the head and neck (SCCHN), nasopharyngeal carcinoma (NPC), and colorectal cancer (CRC). This study was conducted at 7 Chinese centers between April 11, 2018, and March 29, 2021 (data cutoff date). Data analysis took place between April 2021 and June 2021. Interventions An intravenous dose of 0.1 to 2.5 mg/kg of MRG003 was administered every 3 weeks during phase 1a. During phase 1b, patients were administered the recommended dose identified in phase 1a. Main Outcomes and Measures The primary end points were dose-limiting toxic effects in phase 1a and objective response rate in phase 1b. The safety, tolerability, immunogenicity, and pharmacokinetics of MRG003 were assessed. Tumor assessment was evaluated by RECIST 1.1. Results Twenty-two patients (mean [range] age, 54.5 [32.0-67.0] years; 9 women [41%]) were enrolled in phase 1a and 39 patients (mean [range] age, 50.4 [27.0-75.0] years; 8 women [21%]) in phase 1b. The recommended dose was identified as 2.5 mg/kg. Eighty-nine percent of adverse events (AEs) were associated with MRG003 treatment, and most AEs were grade 1 to 2. Nineteen patients (31%) reported grade 3 or greater treatment-related AEs, including hyponatremia, leukocytopenia, neutropenia, increased aspartate aminotransferase levels, and febrile neutropenia. In phase 1a, 1 patient (5%) achieved a partial response, and 5 (23%) achieved stable disease. In phase 1b, 8 patients (21%) achieved a confirmed partial response, and 12 (31%) achieved stable disease. The objective response rates for SCCHN, NPC, and CRC were 40%, 44%, and 0%, and the disease control rates were 100%, 89%, and 25%, respectively. Conclusions and Relevance The findings of this nonrandomized clinical trial suggest that MRG003 showed a manageable safety profile and promising antitumor activity in patients with EGFR-positive NPC and SCCHN.

Abstract
Background Secretory otitis media is a very common nonsuppurative inflammatory disease in otorhinolaryngology. Ambroxol hydrochloride helps to improve ciliary movement in the ear canal and promote the dissolution and discharge of secretions. However, its effect still lacks systematic evaluation. We conducted a meta-analysis of clinical studies to systematically evaluate the application effect of ambroxol hydrochloride. Methods A computer-based search of the Chinese Biomedical Database (CBM), China National Knowledge Infrastructure (CNKI), PubMed, and Web of Science databases was conducted using the keywords “Ambroxol hydrochloride” & “secretory otitis media”. Randomized controlled trials published after 2015 were selected and then screened and analyzed using RevMan 5.4 software. Results Ten studies involving a total of 998 patients were included. Meta-analysis showed that adding ambroxol hydrochloride to the original glucocorticoid treatment improved therapeutic efficacy [odds ratio (OR) =4.95, 95% confidence interval (CI): 3.27, 7.50, P<0.00001], reduced tympanic pressure after treatment [mean difference (MD) =−19.04, 95% CI: −22.72, −15.36, P<0.00001], and increased the pure tone threshold (MD =6.37, 95% CI: 5.36, 7.37, P<0.00001), without increasing adverse reactions (OR =0.51, 95% CI: 0.14, 1.85, P=0.30). Discussion On the basis of the original treatment of secretory otitis media, adding ambroxol hydrochloride treatment improved the therapeutic effect, reduced tympanic pressure after treatment, and improved the pure tone threshold (hearing), without increasing adverse reactions.

Abstract
Alcohol-associated liver disease (ALD) encompasses a wide range of pathologies from simple steatosis to cirrhosis and hepatocellular carcinoma and is a global health problem. Currently, there are no effective pharmacological treatments for ALD. We have previously demonstrated that aging exacerbates the pathogenesis of ALD, but the underlying mechanisms are still poorly understood. Cellular repressor of E1A-stimulated genes 1 protein (CREG1) is a recently identified small glycoprotein that has been implicated in aging process by promoting cellular senescence and activating stress kinases. Thus, the current study aimed to explore the role of aging associated CREG1 in ALD pathogenesis and CREG1 as a potential therapeutic target. Hepatic and serum CREG1 protein levels were elevated in ALD patients. Elevation of hepatic CREG1 protein and mRNA was also observed in a mouse model of Gao-binge alcohol feeding. Genetic deletion of the Creg1 gene in hepatocytes (Creg1∆hep) markedly exacerbated ethanol-induced liver injury, apoptosis, steatosis and inflammation. Compared to wild-type mice, Creg1∆hep mice had increased phosphorylation of hepatic stress kinases such as apoptosis signal-regulating kinase 1 (ASK1), c-Jun N-terminal kinase (JNK) and p38 but not TGF-β-activated kinase 1 (TAK1) or extracellular signal-regulated kinase (ERK) after alcohol feeding. In vitro, ethanol treatment elevated the phosphorylation of ASK1, JNK, and p38 in mouse hepatocyte AML-12 cells. This elevation was further enhanced by CREG1 knockdown but alleviated by CREG1 overexpression. Last, treatment with an ASK1 inhibitor abolished ethanol-induced liver injury and upregulated hepatic lipogenesis, proinflammatory genes and stress kinases in Creg1∆hep mice. Taken together, our data suggest that CREG1 protects against alcoholic liver injury and inflammation by inhibiting the ASK1-JNK/p38 stress kinase pathway and that CREG1 is a potential therapeutic target for ALD.

Abstract
Background: In the past few decades, natural products have become an increasingly important source of potential anti-cancer agents. The green walnut husk(GWH) extracts have been reported to inhibit multiple tumor cells and might be a promising chemopreventive agent in human neoplasia. However, it is not clear whether GWH extracts inhibit gastric cancer. Methods: Proliferation, invasion, and migration of gastric cancer cells were assessed by the CCK-8, wound-healing, and Transwell assay. The apoptotic rate was detected by flow cytometry(FCM). The expressions of Bcl-2, Bax, and Caspase-3 proteins were examined by Western blot. Moreover, the growth of gastric cancer cells was assessed using orthotopic xenograft models, and related proteins expressions were evaluated using immunohistochemistry. Finally, the Gene expression profile of gastric cancer treated with GWH extracts was evaluated by using High-throughput RNA sequencing(RNA-seq). Results: GWH extracts effectively inhibited gastric cancer cell growth in vitro and in vivo. In vivo, GWH extracts inhibited the survival of gastric cancer cells in a dose and time-dependent manner, inhibited the migration and invasion of gastric cancer cells, regulated the expressions of apoptosis-related proteins, and induced apoptosis of gastric cancer cells. In vitro, GWH extracts inhibited the growth of mouse xenografted tumors. A total of differentially expressed genes, of which 41 genes were up-regulated, and 610 genes were down-regulated, were identified by RNA-seq. GO, and KEGG analysis showed that these differentially expressed genes might be related to the mechanism of the anti-gastric cancer effect of GWH extracts. Conclusion: GWH extracts played an anti-gastric cancer effect by inducing apoptosis and inhibiting invasion. Secondly, the differential expression of many genes, multiple signal pathways, and metabolic pathways in gastric cancer play an essential role in the anti-gastric cancer effect of GWH extracts. The results suggested that GWH extracts are expected to be a low toxic drug for the treatment of gastric cancer in the future.
