Abstract
Background: The occurrence and development of Hepatic fibrosis (HF) are closely related to the gut microbial composition and alterations in host metabolism. Qijia Rougan decoction (QJ) is a traditional Chinese medicine compound utilized clinically for the treatment of HF with remarkable clinical efficacy. However, its effect on the gut microbiota and metabolite alterations is unknown. Therefore, our objective was to examine the impact of QJ on the gut microbiota and metabolism in Carbon tetrachloride (CCl4)-induced HF. Methods: 40% CCl4 was used to induce HF, followed by QJ administration for 6 weeks. Serum biochemical analyses, histopathology, immunohistochemistry, RT-PCR, 16S rRNA gene sequencing, and non-targeted metabolomics techniques were employed in this study to investigate the interventional effects of QJ on a CCl4-induced HF model in rats. Results: This study demonstrated that QJ could effectively ameliorate CCl4-induced hepatic inflammation and fibrosis. Moreover, QJ upregulated the expression of intestinal tight junction proteins (TJPs) and notably altered the abundance of some gut microbes, for example, 10 genera closely associated with HF-related indicators and TJPs. In addition, metabolomics found 37 key metabolites responded to QJ treatment and strongly associated with HF-related indices and TJPs. Furthermore, a tight relation between 10 genera and 37 metabolites was found post correlation analysis. Among them, Turicibacter, Faecalibaculum, Prevotellaceae UCG 001, and unclassified Peptococcaceae may serve as the core gut microbes of QJ that inhibit HF. Conclusion: These results suggest that QJ ameliorates hepatic inflammation and fibrosis, which may be achieved by improving intestinal tight junctions and modulating gut microbiota composition as well as modulating host metabolism.

Abstract
BACKGROUND To evaluate the cost-effectiveness of Tislelizumab vs Sorafenib as the first-line treatment of unresectable hepatocellular carcinoma (HCC) from the perspective of the Chinese health service system. METHODS A lifetime partitioned survival model (PSM) was developed to cost-effectively analyze Tislelizumab vs Sorafenib as the first-line treatment of unresectable HCC. The clinical and safety data were derived from a recently randomized clinical trial (RATIONALE-301). Utilities were collected from the published literature. Costs were obtained from an open-access database (http://www.yaozh.com) and previous studies. The model cycle was 21 days, according to the RATIONALE-301 study, and the simulation period was patients' lifetime. Long-term direct medical costs and quality-adjusted life-years (QALYs) were determined. The incremental cost-effectiveness ratio (ICER) was used as the evaluation index. one-way sensitivity analysis (OSWA) and probabilistic sensitivity analysis (PSA) were used to analyze the uncertainty of parameters and to adjust and verify the stability of the baseline results. RESULTS The Tislelizumab group generated a cost of $39,746.34 and brought health benefits to 2.146 QALYs, while the cost and utility of the Sorafenib group were $26750.95 and 1.578 QALYs, respectively. The Tislelizumab group increased QALYs by 0.568, the incremental cost was $12995.39, and the ICER was $22869.64/QALY, lower than the willingness to pay threshold (WTP). OSWA results showed that the utility of progressed disease (PD), cost of Camrelizumab, and cost of Tislelizumab were the main factors affecting the ICER. PSA results showed that, within 1000 times the Monte Carlo simulation, the cost of the Tislelizumab group was lower than three times the per capita gross domestic product (GDP) of China ($37653/QALY). The cost-effectiveness acceptability curves (CEAC) revealed that when WTP was no less than $12251.00, the Tislelizumab group was the dominant scheme, and the economic advantage grew with an increasing WTP. When WTP ≥ $19000.00, the Tislelizumab group became the absolute economic advantage. CONCLUSION Under the current economic conditions in China, the Tislelizumab therapeutic scheme is more cost-effective than the Sorafenib therapeutic scheme for treating patients with unresectable HCC.

Abstract
OBJECTIVES To compare longitudinal changes in cervical length (CL) and mean cervical shear wave elastography (CSWE) scores between women with singleton and twin pregnancies who experience spontaneous preterm birth (sPTB) and those who have term births (TB). METHODS This was a prospective longitudinal study of 1264 unselected women with singleton (n=1143) and twin (n=121) pregnancy attending a dedicated research clinic for screening of sPTB at 4 timepoints during pregnancy including 11-15+6 (visit 1), 16-20+6 (visit 2), 21-24+6 (visit 3) and 28-32+6 (visit 4) weeks of gestation. At each visit, a transvaginal ultrasound scan was conducted to measure the CL and the CSWE scores from six regions of interest (ROI) (inner, middle, and external parts of anterior and posterior lips) in the cervix. The mean of CSWE scores from the six ROIs were calculated for data analysis. Log10 transformation was applied to make the data Gaussian prior to statistical analysis. A multilevel mixed-effects analysis was performed to compare CL and CSWE longitudinally between sPTB and TB groups. RESULTS A total of 57 (4.99%) singleton pregnancies and 33 (27.27%) twin pregnancies were complicated with sPTB. Women with sPTB had shorter CL across gestation when controlling for history of cervical surgery, number of fetuses, gestational age at cervical assessment (GA), and the interaction between GA and sPTB. CL in the sPTB group was significantly lower than that of the TB group at 21-24+6 weeks (p=0.039) and 28-32+6 weeks (p<0.001). Twin pregnancies had significantly longer CL throughout pregnancy, compared to singleton pregnancies (coefficient=0.01864, p<0.001). Furthermore, after adjusting for maternal age, weight, height, body mass index (BMI), and GA, CSWE scores in sPTB group were significantly lower in the sPTB group across gestation, compared to the TB group (1.28265 vs 1.32832; p=0.013). However, in the individual visit analysis, CSWE scores in the sPTB group were significantly lower than that of the TB group only at 11-15+6 weeks (p=0.013). There was no difference in CSWE scores between singleton and twin pregnancies throughout pregnancy (coefficient=-0.00128, p=0.937). CONCLUSION Women with sPTB have shorter CL and softer cervix across gestation when compared to those with TB. In the individual visit analysis, the reduction in CL in the sPTB group occurs from late second trimester onwards, while the reduction in cervical stiffness in the sPTB group is observed primarily in the first trimester. Additionally, our study has found that CL is significantly shorter in singleton pregnancies compared to twin pregnancies, while cervical stiffness does not differ between the two types of pregnancy. Our findings indicate that the cervix tends to undergo a softening process prior to shortening in the sPTB cases This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND AND OBJECTIVE Recently, computational fluid dynamics enables the non-invasive calculation of fractional flow reserve (FFR) based on 3D coronary model, but it is time-consuming. Currently, machine learning technique has emerged as an efficient and reliable approach for prediction, which allows saving a lot of analysis time. This study aimed at developing a simplified FFR prediction model for rapid and accurate assessment of functional significance of stenosis. METHODS A reduced-order lumped parameter model (LPM) of coronary system and cardiovascular system was constructed for rapidly simulating coronary flow, in which a machine learning model was embedded for accurately predicting stenosis flow resistance at a given flow from anatomical features of stenosis. Importantly, the LPM was personalized in both structures and parameters according to coronary geometries from computed tomography angiography and physiological measurements such as blood pressure and cardiac output for personalized simulations of coronary pressure and flow. Coronary lesions with invasive FFR ≤ 0.80 were defined as hemodynamically significant. RESULTS A total of 91 patients (93 lesions) who underwent invasive FFR were involved in FFR derived from machine learning (FFRML) calculation. Of the 93 lesions, 27 lesions (29.0%) showed lesion-specific ischemia. The average time of FFRML simulation was about 10 min. On a per-vessel basis, the FFRML and FFR were significantly correlated (r = 0.86, p < 0.001). The diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value were 91.4%, 92.6%, 90.9%, 80.6% and 96.8%, respectively. The area under the receiver-operating characteristic curve of FFRML was 0.984. CONCLUSION In this selected cohort of patients, the FFRML improves the computational efficiency and ensures the accuracy. The favorable performance of FFRML approach greatly facilitates its potential application in detecting hemodynamically significant coronary stenosis in future routine clinical practice.

Abstract
BACKGROUND AND OBJECTIVE The functional assessment of the severity of coronary stenosis from coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFR) has recently attracted interest. However, existing algorithms run at high computational cost. Therefore, this study proposes a fast calculation method of FFR for the diagnosis of ischemia-causing coronary stenosis. METHODS We combined CCTA and machine learning to develop a simplified single-vessel coronary model for rapid calculation of FFR. First, a zero-dimensional model of single-vessel coronary was established based on CCTA, and microcirculation resistance was determined through the relationship between coronary pressure and flow. In addition, a coronary stenosis model based on machine learning was introduced to determine stenosis resistance. Computational FFR (cFFR) was then obtained by combining the zero-dimensional model and the stenosis model with inlet boundary conditions for resting (cFFRr) and hyperemic (cFFRh) aortic pressure, respectively. We retrospectively analyzed 75 patients who underwent clinically invasive FFR (iFFR), and verified the model accuracy by comparison of cFFR with iFFR. RESULTS The average computing time of cFFR was less than 2 s. The correlations between cFFRr and cFFRh with iFFR were r = 0.89 (p < 0.001) and r = 0.90 (p < 0.001), respectively. Diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio for cFFRr and cFFRh were 90.7%, 95.0%, 89.1%, 76.0%, 98.0%, 8.7, 0.1 and 92.0%, 95.0%, 90.9%, 79.2%, 98.0%, 10.5, 0.1, respectively. CONCLUSIONS The proposed model enables rapid prediction of cFFR and exhibits high diagnostic performance in selected patient cohorts. The model thus provides an accurate and time-efficient computational tool to detect ischemia-causing stenosis and assist with clinical decision-making.

Abstract
Liver depression and spleen deficiency syndrome (LDSDS) and spleen-gastric damp-heat syndrome (SGDHS) are two major traditional Chinese medicine syndromes observed in chronic hepatitis B (CHB). Both syndromes exhibit significant differences in the pathogenesis and prognosis, and are closely related to the immune system. However, the underlying mechanisms are largely unknown. This study aimed to explore the immunoregulatory mechanisms of the two syndromes and promote the differentiation precision between the two syndromes. Thirty-six patients with CHB (18 LDSDS patients and 18 SGDHS patients) and 14 healthy controls were recruited into this study and blood was collected from all the subjects for testing. We studied the contents of T lymphocytes by flow cytometry and the expression levels of HMGB1/PTEN/PI3K axis proteins by enzyme-linked immunosorbent assay (Elisa). Protein-protein interaction (PPI) networks among HMGB1/PTEN/PI3K axis were constructed for functional enrichment. The correlations between T lymphocytes and proteins were analyzed by constructing multiple regression equations. The results revealed that the CD8+ T cells level in the two syndromes were lower than that in healthy controls, and the levels of Th17, Treg cells, and HMGB1, PI3K, PDK1, Akt were higher than those of the healthy controls (p < 0.05). Moreover, the levels of CD4+ T, Th17 cells, and HMGB1, PTEN, PI3K in LDSDS were higher than SGDHS (p < 0.05). PPI network indicated that HMGB1/PTEN/PI3K axis participated in T cell activation and liver pathology. Our results revealed that HMGB1/PTEN/PI3K axis may play an important role in regulating the formation of peripheral immune differences between the two syndromes. CD4+ T and Th17 are two representative immune cells that may serve as potential biological markers for LDSDS and SGDHS in CHB.

Abstract
Oral microbial community, as an important part of human microbial community, is closely related to oral and general health. Oral microbiological research has become the forefront of international microbiological research. Standardized and unified nomenclature for oral microorganisms in Chinese is of great significance to support the development of oral medicine research. Standardized translation of microbial names is the basis for writing canonical and authoritative professional textbooks and reference books, which helps students to accurately acquire the characteristics and classifications of oral microbes. Unified translation of oral microorganisms is also conducive to academic communication and cooperation, and plays an important role in oral health education and science popularization, which enables oral microbiology knowledge to be accurately disseminated to the public. Therefore, in order to standardize the words in scientific research, funding application, publications, academic exchanges and science popularization within the field of oral medicine, we have fully discussed and revised the Chinese names of oral microorganisms in 2017 edition and ones of newly discovered oral microbes, finally reaching a consensus to form the 2023 edition of Chinese names of oral microorganisms.

Abstract
PURPOSE/OBJECTIVE(S) Patients with N2 non-small cell lung cancer (NSCLC) were heterogeneous groups and required further stratification. The International Society for the Study of Lung Cancer (IASLC) added new descriptors of three sub-stages for stage N2 NSCLC: N2 at a single station without N1 involvement (N2a1), N2 at a single station with N1 involvement (N2a2), and N2 at multiple stations (N2b). This study aimed to investigate the efficacy of postoperative radiotherapy (PORT) for patients with these N2 descriptors. MATERIALS/METHODS Patients with histologically confirmed NSCLC after complete resection and divided into PORT group and non-PORT group. The primary endpoint was DFS. The second endpoints were overall survival (OS) and locoregional recurrence-free survival (LRFS). Propensity-score matching (PSM) of baseline characteristics between the PORT and non-PORT groups was used for validation. RESULTS Totally 1832 patients were enrolled, including 308 N2a1 patients, 682 N2a2 patients, and 842 N2b patients. The median follow-up time was 50.1 months. The survival outcomes of the PORT and non-PORT groups before PSM were shown in Table 1. For patients with N2a1, PORT could not improve the DFS (median DFS of the PORT group and the non-PORT group: not reached vs. 46.8 months, P = 0.41), OS (P = 0.85), or LRFS (P = 0.32), which were consistent with the multivariate analysis and data after the PSM. For patients with N2a2, PORT significantly improved the DFS (median DFS 29.7 vs. 22.2 months, P = 0.02), OS (P = 0.03), and LRFS (P = 0.01). The multivariate analysis and data after the PSM confirmed the benefits in DFS and LRFS, but no benefit was observed in OS (multivariate analysis: HR 0.79, P = 0.18; median OS after PSM: 103.7 vs. 63.1 months, P = 0.34). For patients with N2b, PORT could not improve the DFS (median DFS 20.6 vs. 21.2 months, P = 0.39) but significantly improved the OS (P<0.001) and LRFS (P<0.001). However, the multivariate analysis showed that PORT significantly improved DFS (HR 0.81, P = 0.03), consistent with the data after the PSM (median DFS 20.6 and 17.6 months, P = 0.04). CONCLUSION PORT significantly improved the DFS and LRFS in patients with N2a2 and significantly improved the DFS, LRFS, and OS in patients with N2b. Patients with N2a1 could not benefit from PORT.

Abstract
PURPOSE/OBJECTIVE(S) To evaluate the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-PTX) plus cisplatin as the regimen of conversional chemoradiotherapy (cCRT) in locally advanced borderline resectable or unresectable esophageal squamous cell carcinoma (ESCC). MATERIALS/METHODS Patients with locally advanced ESCC (cT3-4, Nany, M0-1, M1 was limited to lymph node metastasis in the supraclavicular area) were enrolled. All the patients received the cCRT of nab-PTX plus cisplatin. After the cCRT, those resectable patients received esophagectomy; those unresectable patients continued to receive the definitive chemoradiotherapy (dCRT). The locoregional control (LRC), overall survival (OS), progression-free survival (PFS), distant metastasis free survival (DMFS), pathological complete response (pCR), R0 resection rate and adverse events (AEs) were calculated. RESULTS A total of 45 patients with ESCC treated from October 2019 to May 2021 were finally included. The median follow-up time was 30.3 months. The LRC, OS, EFS, DMFS at 1and 2 years were 81.5%, 86.6%, 64.3%, 73.2% and 72.4%, 68.8%, 44.8%, 52.7% respectively. 21 patients (46.7%) received conversional chemoradiotherapy plus surgery (cCRT+S). The pCR rate and R0 resection rate were 47.6% and 84.0%. The LRC rate at 1 and 2 years were 95.0%, 87.1% in cCRT+S patients and 69.3%, 58.7% in dCRT patients respectively (HR, 5.14; 95% CI, 1.10-23.94; P = 0.021). The OS rate at 1 and 2 years were 95.2% and 84.2% in resectable patients compared to 78.8% and 54.4% in unresectable patients (HR, 3.41; 95% CI, 1.10-10.61; P = 0.024). The toxicities during chemoradiotherapy were tolerated, the most common grade 3-4 toxicities were radiation esophagitis (15.6%). CONCLUSION Nab-PTX plus cisplatin were effective and safe as the regimen of conversional chemoradiotherapy of ESCC. The patients receiving conversional chemoradiotherapy plus surgery (cCRT+S) were prone to have a better survival.

Abstract
Yueju pill, a classic Chinese Medicine formulated, was recently found to produce rapid antidepressant-like effects in a PKA-CREB signaling-dependent manner. In our study, we found that the Yueju pill induced a remarkable increase in PACAP. The intracerebroventricular injection of PACAP agonist induced a rapid antidepressant-like effect; conversely, the intrahippocampal infusion of a PACAP antagonist reversed the antidepressant response of the Yueju pill. Mice with hippocampal PACAP knockdown via viral-mediated RNAi displayed depression-like behavior. PACAP knockdown also blunted the antidepressant effect of the Yueju pill. PACAP knockdown resulted in down-regulated CREB and expression of the synaptic protein PSD95 at both baselines and after administration of the Yueju pill. However, administration of the Yueju pill in the knockdown mice promoted PACAP and PKA levels. Chronically stressed mice showed deficient hippocampal PACAP-PKA-CREB signaling and depression-like behavior, which were reversed by a single dose of the Yueju pill. In this study, we demonstrated that the up-regulation of PACAP induced activating of PKA-CREB signaling would play a part in the rapid antidepressant-like effects of the Yueju pill. We also identified iridoids fraction of Gardenia jasminoides Ellis (GJ-IF), a vital component of the Yueju pill, was identified to recapitulate rapid antidepressant-like behavior through increased hippocampal PACAP expression of the Yueju pill. The promotion of hippocampal PACAP may collectively represent a novel mechanism of rapid antidepressant-like effect.

Abstract
RNA-binding proteins (RBPs), being pivotal elements in both physiological and pathological processes, possess the ability to directly impact RNA, thereby exerting a profound influence on cellular life. Furthermore, the dysregulation of RBPs not only induces alterations in the expression levels of genes associated with cancer but also impairs the occurrence of post-transcriptional regulatory mechanisms. Consequently, these circumstances can give rise to aberrations in cellular processes, ultimately resulting in alterations within the proteome. An aberrant proteome can disrupt the equilibrium between oncogenes and tumor suppressor genes, promoting cancer progression. Given their significant role in modulating gene expression and post-transcriptional regulation, directing therapeutic interventions towards RBPs represents a viable strategy for combating drug resistance in cancer treatment. RBPs possess significant potential as diagnostic and prognostic markers for diverse cancer types. Gaining comprehensive insights into the structure and functionality of RBPs, along with delving deeper into the molecular mechanisms underlying RBPs in tumor drug resistance, can enhance cancer treatment strategies and augment the prognostic outcomes for individuals afflicted with cancer.

Abstract
OBJECTIVE To propose an deep learning-based algorithm for automatic prediction of dose distribution in radiotherapy planning for head and neck cancer. METHODS We propose a novel beam dose decomposition learning (BDDL) method designed on a cascade network. The delivery matter of beam through the planning target volume (PTV) was fitted with the pre-defined beam angles, which served as an input to the convolution neural network (CNN). The output of the network was decomposed into multiple sub-fractions of dose distribution along the beam directions to carry out a complex task by performing multiple simpler sub-tasks, thus allowing the model more focused on extracting the local features. The subfractions of dose distribution map were merged into a distribution map using the proposed multi-voting mechanism. We also introduced dose distribution features of the regions-of-interest (ROIs) and boundary map as the loss function during the training phase to serve as constraining factors of the network when extracting features of the ROIs and areas of dose boundary. Public datasets of radiotherapy planning for head and neck cancer were used for obtaining the accuracy of dose distribution of the BDDL method and for implementing the ablation study of the proposed method. RESULTS The BDDL method achieved a Dose score of 2.166 and a DVH score of 1.178 (P < 0.05), demonstrating its superior prediction accuracy to that of current state-ofthe-art (SOTA) methods. Compared with the C3D method, which was in the first place in OpenKBP-2020 Challenge, the BDDL method improved the Dose score and DVH score by 26.3% and 30%, respectively. The results of the ablation study also demonstrated the effectiveness of each key component of the BDDL method. CONCLUSION The BDDL method utilizes the prior knowledge of the delivery matter of beam and dose distribution in the ROIs to establish a dose prediction model. Compared with the existing methods, the proposed method is interpretable and reliable and can be potentially applied in clinical radiotherapy.

Abstract
Background: Observational studies have shown that anti-tumor necrosis factor (TNF) therapy may be beneficial for patients with coronavirus disease 2019 (COVID-19). Nevertheless, because of the methodological restrictions of traditional observational studies, it is a challenge to make causal inferences. This study involved a two-sample Mendelian randomization analysis to investigate the causal link between nine TNFs and COVID-19 severity using publicly released genome-wide association study summary statistics. Methods: Summary statistics for nine TNFs (21,758 cases) were obtained from a large-scale genome-wide association study. Correlation data between single-nucleotide polymorphisms and severe COVID-19 (18,152 cases vs. 1,145,546 controls) were collected from the COVID-19 host genetics initiative. The causal estimate was calculated by inverse variance-weighted (IVW), MR-Egger, and weighted median methods. Sensitivity tests were conducted to assess the validity of the causal relationship. Results: Genetically predicted TNF receptor superfamily member 6 (FAS) positively correlated with the severity of COVID-19 (IVW, odds ratio = 1.10, 95% confidence interval = 1.01-1.19, p = 0.026), whereas TNF receptor superfamily member 5 (CD40) was protective against severe COVID-19 (IVW, odds ratio = 0.92, 95% confidence interval = 0.87-0.97, p = 0.002). Conclusion: Genetic evidence from this study supports that the increased expression of FAS is associated with the risk of severe COVID-19 and that CD40 may have a potential protective effect against COVID-19.

Abstract
The present network meta-analysis aimed to enhance the corresponding evidence with respect to the efficacy and safety of pharmaceuticals treatments. Frequentist network meta-analysis was used. Medical literature up to November 2022 was searched for randomized clinical trials assessing the efficacy and safety of these pharmaceuticals, either compared with each other or compared with placebo. With the exception of ranitidine (300 mg four times daily) and vonoprazan (20 mg once daily) having lower safety than placebo, the efficacy and safety of the remaining treatments were superior to placebo. Cimetidine (400 mg four times daily) and pantoprazole (40 mg once daily) were ranked first in terms of efficacy. The frequentist network meta-analysis shows that for cimetidine (except 400 mg once daily), famotidine, rabeprazole, ilaprazole, lansoprazole (except 7.5 mg once daily) and omeprazole (except 10 mg once daily or 30 mg once daily), the efficacy comparison between the different doses of each of the aforementioned pharmaceuticals did not indicate statistically significant differences. In conclusion, pantoprazole (40 mg once daily) was the best choice for the initial non-eradication treatment of patients with duodenal ulcer, and cimetidine (400 mg twice daily), omeprazole (20 mg once daily), lansoprazole (15 mg once daily), ilaprazole (5 mg once daily) and rabeprazole (10 mg once daily) could be used as the first choice. If the aforementioned pharmaceuticals cannot be prescribed, famotidine (40 mg twice daily) is recommended.

Abstract
Background: In recent years, the incidence and mortality rates of chronic obstructive pulmonary disease (COPD) have increased significantly. Erchen Decoction combined with Xiebai Powder (ECXB) formula is mainly used to treat lung diseases in traditional Chinese medicine (TCM). However, the active ingredients of ECXB formula, COPD treatment-related molecular targets, and the mechanisms are still unclear. To reveal its underlying action of mechanism, network pharmacology, molecular docking, and molecular dynamic (MD) simulation approaches were used to predict the active ingredients and potential targets of ECXB formula in treating COPD. As a result, Herb-Symptom analysis showed that the symptoms treated by both TCM and modern medicine of ECXB formula were similar to the symptoms of COPD. Network pharmacology identified 170 active ingredients with 137 targets, and 7,002 COPD targets was obtained. 120 targets were obtained by intersection mapping, among which the core targets include MAPK8, ESR1, TP53, MAPK3, JUN, RELA, MAPK1, and AKT1. Functional enrichment analysis suggested that ECXB formula might exert its treat COPD pharmacological effects in multiple biological processes, such as cell proliferation, apoptosis, inflammatory response, and synaptic connections, and ECXB formula treated COPD of the KEGG potential pathways might be associated with the TNF signaling pathway, cAMP signaling pathway, and VEGF signaling pathway. Molecular docking showed that ECXB formula treatment COPD core active ingredients can bind well to core targets. MD simulations showed that the RELA-beta-sitosterol complex and ESR1-stigmasterol complex exhibited higher conformational stability and lower interaction energy, further confirming the role of ECXB formula in the treatment of COPD through these core components and core targets. Our study analyzed the medication rule of ECXB formula in the treatment of COPD from a new perspective and found that the symptoms treated by both TCM and modern medicine of ECXB formula were similar to the symptoms of COPD. ECXB formula could treat COPD through multi-component, multi-target, and multi-pathway synergistic effects, providing a scientific basis for further study on the mechanism of ECXB formula treatment of COPD. It also provides new ideas for drug development.

Abstract
BACKGROUND Epidemiological studies have reported associations between subjective well-being (SWB), depression, and suicide with COVID-19 illness, but the causality has not been established. We performed a two-sample Mendelian randomization (MR) analysis to investigate the causal link between SWB, depression, suicide and COVID-19 susceptibility and severity. METHODS Summary statistics for SWB (298,420 cases), depression (113,769 cases) and suicide (52,208 cases) were obtained from three large-scale GWAS. Data on the associations between the Single Nucleotide Polymorphisms (SNPs) and COVID-19 (159,840 cases), hospitalized COVID-19 (44,986 cases), and severe COVID-19 (18,152 cases) were collected from the COVID-19 host genetics initiative. The causal estimate was calculated by the Inverse Variance Weighted, MR Egger and Weighted Median methods. Sensitivity tests were used to evaluate the validity of the causal relationship. RESULTS Our results showed that genetically predicted SWB (OR = 0.98, 95 % CI: 0.86-1.10, P = 0.69), depression (OR = 0.76, 95 % CI: 0.54-1.06, P = 0.11), and suicide (OR = 0.99, 95 % CI: 0.96-1.02, P = 0.56) were not causally related to COVID-19 susceptibility. Similarly, we did not find a potential causal relationship between SWB, depression, suicide and COVID-19 severity. CONCLUSIONS This indicated that positive or negative emotions would not make COVID-19 better or worse, and strategies that attempted to use positive emotions to improve COVID-19 symptoms may be useless. Improving knowledge about the SARS-CoV-2 and timely medical intervention to reduce panic during a pandemic is one of the effective measures to deal with the current decrease in well-being and increase in depression and suicide rates.

Abstract
Background Chinese herbal injections (CHIs) are commonly prescribed in China as adjuvant therapy for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, evidence supporting the effect of CHIs on inflammatory factors for patients with AECOPD is insufficient, posing a challenge for clinicians to choose the optimal CHIs for AECOPD. This network meta-analysis (NMA) aimed to compare the effectiveness of several CHIs combined with Western Medicine (WM) and WM alone on the inflammatory factors in AECOPD. Methods Randomized controlled trials (RCTs) on different CHIs for treating AECOPD were thoroughly searched from several electronic databases up to August 2022. The quality assessment of the included RCTs was conducted according to the Cochrane risk of bias tool. Bayesian network meta-analyses were designed to assess the effectiveness of different CHIs. Systematic Review Registration CRD42022323996. Results A total of 94 eligible RCTs involving 7,948 patients were enrolled in this study. The NMA results showed that using Xuebijing (XBJ), Reduning (RDN), Tanreqing (TRQ), and Xiyanping (XYP) injections combined with WM significantly improved treatment effects compared to using WM alone. XBJ + WM and TRQ + WM significantly changed the level of C-reactive protein (CRP), white blood cells, percentage of neutrophils, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). TRQ + WM showed the most significant effect in reducing the level of procalcitonin. XYP + WM and RDN + WM could reduce the level of white blood cells and the percentage of neutrophils. A total of 12 studies reported adverse reactions in detail, and 19 studies demonstrated no significant adverse reactions. Conclusions This NMA showed that using CHIs combined with WM could significantly reduce the level of inflammatory factors in AECOPD. A combination of TRQ and WM may be a relatively prior adjuvant therapy option for AECOPD treatment considering its effects in reducing the levels of the anti-inflammatory mediators.

Abstract
OBJECTIVE To compare the parental acceptance of dental treatment under general anesthesia and deep sedation in children and assess the changes in postoperative oral health-related quality of life and treatment efficacy. METHODS The parents of 131 children undergoing dental treatment in the Department of Stomatology of Sichuan Provincial People's Hospital from January, 2022 to June, 2022 were surveyed using a questionnaire of children's advanced oral behavior management, and 83 children receiving general anesthesia or deep sedation for dental treatment between January, 2018 and December, 2021 were also investigated for changes in quality of life after the treatment using a questionnaire. The treatment efficacy was assessed at the 1-year follow-up visit in 149 children who received dental treatment under general anesthesia or deep sedation during the same period. RESULTS The survey of perantal acceptance showed that 62.6% of the parents preferred deep sedation, 29.01% preferred general anesthesia, and 8.4% preferred compulsory treatment. Dental treatments under general anesthesia and deep sedation both significantly improved oral health-related quality of life of the children. While dental surgeries under general anesthesia resulted in the most significant improvement of pain symptoms, deep sedation was associated with both obvious relief of the children's pain symptoms and reduction of the parents' pressure level. No significant difference was found in the efficacy of treatments under general anesthesia and deep sedation at the 1-year follow-up. CONCLUSION Dental treatment in children under deep sedation has the highest parental acceptance, followed by treatment under general anesthesia, and the acceptance of compulsory treatment is the lowest. The treatments under general anesthesia and deep sedation significantly improve the quality of life of the children and their parents and both have good treatment efficacy.

Abstract
Non-alcoholic steatohepatitis (NASH) is a metabolic disorder that often leads to other severe liver diseases, yet treatment options are limited. Endoplasmic reticulum (ER) stress is an important pathogenetic mechanism of NASH and plays a key role in tandem steatosis as well as liver inflammation. This study aims to develop a progressive NASH model through sustained lipid accumulation and to elucidate its molecular mechanism through IRE1α/TRAF2 complex. Male SD rats were fed a high-fat diet (HFD) for 4, 8, and 12 weeks to induce progressive NASH. MRNA sequencing and PPI analysis were used to screen core genes. Transmission electron microscopy, immunofluorescence staining, ELISA, qRT-PCR, and Western blotting were used at each time point to compare differences between each index of progressive NASH at 4, 8, and 12 weeks. Sustained lipid accumulation led to structural disruption of the ER, a reduction in ER number, and an increase of lipid droplet aggregation in hepatocytes. Persistent lipid accumulation led to a persistent increase in mRNA and protein expression of the IRE1α/TRAF2 complex, IKK/IκB/NF-κB signaling pathway and ASK1/JNK1 signaling pathway, and TNF-α, IL-1β, and IL-6 also continued to increase. Persistent lipid accumulation led to a persistent exacerbation of ER stress and inflammation in progressive NASH via the IRE1α/TRAF2 complex.

Abstract
The generation of low emittance electron beams from laser-driven wakefields is crucial for the development of compact x-ray sources. Here, we show new results for the injection and acceleration of quasimonoenergetic electron beams in low amplitude wakefields experimentally and using simulations. This is achieved by using two laser pulses decoupling the wakefield generation from the electron trapping via ionization injection. The injection duration, which affects the beam charge and energy spread, is found to be tunable by adjusting the relative pulse delay. By changing the polarization of the injector pulse, reducing the ionization volume, the electron spectra of the accelerated electron bunches are improved.

Abstract
Despite considerable variation in disease manifestations observed among coronavirus disease 2019 (COVID-19) patients infected with severe acute respiratory syndrome coronavirus 2, the risk factors predicting disease severity remain elusive. Recent studies suggest that peripheral blood cells play a pivotal role in COVID-19 pathogenesis. Here, we applied two-sample Mendelian randomization (MR) analyses to evaluate the potential causal contributions of blood cell indices variation to COVID-19 severity, using single-nucleotide polymorphisms (SNPs) as instrumental variables for 17 indices from the UK Biobank and INTERVAL genome-wide association studies (N = 173 480). Data on the associations between the SNPs and very severe respiratory confirmed COVID-19 were obtained from the COVID-19 host genetics initiative (N = 8779/1 001 875). We observed significant negative association between hematocrit (HCT; odds ratio, OR = 0.775, 95% confidence interval, CI = 0.635-0.915, p = 3.48E-04) or red blood cell count (OR = 0.830, 95% CI = 0.728-0.932, p = 2.19E-03) and very severe respiratory confirmed COVID-19, as well as nominal negative association of hemoglobin concentration (OR = 0.808, 95% CI = 0.673-0.943, p = 3.95E-03) with very severe respiratory confirmed COVID-19 (no effect survived multiple correction). In conclusion, the MR study supports a protective effect of high HCT and red blood cell count from very severe respiratory confirmed COVID-19, suggesting potential strategies to ameliorate/treat clinical conditions in very severe respiratory confirmed COVID-19.

Abstract
BACKGROUND Meta-analysis was used to evaluate the efficacy of Fufang Biejia Ruangan Tablets in the treatment of chronic hepatitis B (CHB) liver fibrosis. METHODS Databases, including PubMed, China Knowledge Network (CNKI), China Biomedical Database (CBM), Wan Fang, VIP database, Embase, and Cochrane Library were searched. The time was searched up to May 2022. The participant intervention comparator outcomes of this study were as follows: P, patients with CHB liver fibrosis; I, Fufang Biejia Ruangan Tablets; C, pharmacological placebo; O, the efficacy rate, alanine transaminase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), albumin (ALB), procollagen III protein (PIIIP), hyaluronic acid (HA), laminin (LN), collagen C type IV (IV-C), portal vein diameter, spleen thickness and HBV-DNA negative conversion rate. The Cochrane Risk of Bias tool, Begg's test and Egger's test were used to evaluate the methodological quality of eligible studies. A randomized controlled trial of Fufang Biejia Ruangan Tablets was used to treat CHB liver fibrosis. Three reviewers independently selected trials, extracted data, cross-checked, and performed methodological quality assessments. Data analysis was completed by Review Manager 5.3. RESULTS Twenty-six studies with 2717 patients were included in the meta-analysis. The meta-analysis showed that Fufang Biejia Ruangan Tablets was effective by increasing the efficacy. Fufang Biejia Ruangan Tablets was more efficient in improving ALT, AST, TBIL, ALB, PIIIP, HA, LN, IV-C, portal vein diameter, spleen thickness, and HBV-DNA negative conversion rate with no serious adverse reactions. CONCLUSION It was shown that Fufang Biejia Ruangan Tablets can effectively improve liver function and relieve liver fibrosis, but future research should focus on rigorously designed, multicenter, and large randomized controlled trials.

Abstract
OBJECTIVE To investigate the regulatory role of α-1, 6-fucosyltransferase (FUT8) in TGF-β1-induced proliferation, migration and fibrosis of human embryonic lung fibroblasts (MRC-5 cells) and explore the underlying molecular mechanism. METHODS C57/BL6 mice were randomized into 4 groups for treatment with saline (control group), bleomycin, bleomycin+sh-NC or bleomycin+sh-FUT8, and pulmonary fibrosis was observed using Masson staining.MRC-5 cells were transfected with si-NC, FUT8 siRNA (si-FUT8), or both si-FUT8 and a galectin-3(Gal-3) overexpression plasmid (pcDNA3.1-Gal) prior to TGF-β1 treatment, and the changes in cell proliferation and migration were assessed using CCK-8 assay, BrdU assay, and wound healing assay; the changes in the expression levels of α-SMA, collagen I (COLIA1) and extracellular matrix fibronectin (FN) were detected with real-time quantitative PCR (RT-qPCR) and Western blotting.The interaction of FUT8 and Gal-3 was tested using coimmunoprecipitation (Co-IP) assay, and the effect of FUT8 silencing on Gal-3 and FAK/Akt signaling pathways was analyzed. RESULTS FUT8 knockdown significantly reduced bleomycin-induced extracellular collagen deposition in the lung tissues of the mice.Silencing FUT8 obviously inhibited cell proliferation (P < 0.05) and migration mediated by TGF-β1.FUT8 knockdown down-regulated the mRNA and protein levels of α-SMA, COLIA1 and FN (P < 0.05) in the cells.Coimmunoprecipitation analysis showed that FUT8 interacted with Gal-3.Silencing FUT8 significantly down-regulated Gal-3 expression and inhibited the activation of the FAK/Akt signaling pathway (P < 0.05).Overexpression of Gal-3 obviously reversed the effects of FUT8 silencing on cell proliferation, migration and fibrosis (P < 0.05). CONCLUSION FUT8 regulates TGF-β1-induced proliferation, migration and fibrosis of MRC-5 cells by modulating Gal-3 expression, in which the FAK/Akt pathway may play a role.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a major threat to human health due to its high lethality. Our previous studies suggested that Fuzheng Xiaozheng prescription (FZXZP), an effective Chinese medicine, demonstrated significant suppressive effects on HCC. However, its underlying mechanism remains largely unclear. PURPOSE This study aimed to investigate the anti-HCC mechanisms of FZXZP from transcriptomic sequencing based on a holistic perspective. METHODS Rat HCC model was induced by diethylnitrosamine, and then the model was administered with two doses of FZXZP, high and low. Sodium demethylcantharidate was used as a positive control. Subsequently, microarrays of circRNA, miRNA and mRNA were performed on the blank, model, high and low dose groups, respectively, and the competitive binding mechanisms among them were further analyzed by bioinformatics. Then, the circRNA-miRNA-mRNA networks were constructed to mine the targeted-RNAs of FZXZP in HCC, as well as to explore their potential regulatory mechanisms. Finally, functions and pathways of the FZXZP targeted genes in rat HCC were annotated with GO and KEGG, and qRT-PCR was performed to validate the accuracy of the above analyses in this study. RESULTS The results showed that FZXZP significantly inhibited the development and progression of HCC in rats, improved the pathological conditions and suppressed the proliferation of HCC cells. Subsequently, after a series of screening, the competing endogenous RNA networks (circRNA-miRNA-mRNA), consisting of 2 circRNAs, 7 miRNAs and 104 mRNAs, were finally established. KEGG and GO analyses of the networks revealed that lipid metabolism related pathways, such as fatty acid metabolism, bile secretion and PPAR pathway, were significantly enriched. In the further hubgene network analysis, in addition to lipid metabolism, aberrant glucose metabolism was found to be ameliorated by G6pc and Pklr in hubgenes. Finally, the qRT-PCR analyses confirmed that the expression tendencies of the above targeted genes were correct and believable in transcriptomic sequencings, and qRT-PCR results of the genes closely related to proliferation, invasion and apoptosis of HCC also indicated the inhibitory effects of FZXZP on HCC obviously. CONCLUSION FZXZP demonstrated significant anti-HCC effects through improving lipid and glucose metabolism, restoring the metabolic homeostasis of the liver via circRNA-miRNA-mRNA networks.

Abstract
OBJECTIVES To determine whether first-trimester biomarkers of placental function can be used to screen for spontaneous preterm birth (sPTB), and to develop prediction models using maternal factors, obstetric history and biomarkers of placental function at 11-13 weeks for the calculation of patient-specific risk for sPTB. METHODS This was a retrospective secondary analysis of data derived from a prospective cohort study on first-trimester screening for pre-eclampsia in singleton pregnancies attending for routine Down syndrome screening at 11 + 0 to 13 + 6 weeks' gestation at a tertiary obstetric unit between December 2016 and September 2019. A split-sample internal validation method was used to explore and develop prediction models for all sPTB at < 37 weeks and for PTB at < 37 weeks after preterm prelabor rupture of membranes (PPROM) using maternal risk factors, uterine artery Doppler indices, serum placental growth factor (PlGF), pregnancy-associated plasma protein-A (PAPP-A) and β-human chorionic gonadotropin (β-hCG). Screening performance was assessed using receiver-operating-characteristics (ROC)-curve analysis, with calculation of the areas under the ROC curves (AUCs). RESULTS A total of 9298 singleton pregnancies were included in this study. sPTB at < 37 weeks occurred in 362 (3.89%) cases, including 231 (2.48%) cases of PPROM. sPTB at < 34 weeks occurred in 87 (0.94%) cases, including 39 (0.42%) cases of PPROM. Identified maternal risk factors for sPTB at < 37 weeks included chronic hypertension, conception using in-vitro fertilization and history of PTB. Maternal risk factors for PPROM at < 37 weeks included conception using in-vitro fertilization and history of PTB. Median PlGF multiples of the median (MoM) and PAPP-A MoM were significantly reduced in women with sPTB at < 37 weeks, as well as in those who had PPROM, compared to those who delivered at term. Screening by a combination of maternal risk factors, PAPP-A and PlGF achieved better performance in predicting sPTB at < 37 weeks (AUC, 0.630 vs 0.555; detection rate (DR), 24.8% vs 16.6% at a false-positive rate (FPR) of 10%; P ≤ 0.0001) and PPROM at < 37 weeks (AUC, 0.643 vs 0.558; DR, 28.1% vs 17.0% at a FPR of 10%; P ≤ 0.0001) than using maternal risk factors alone. Both models were successfully applied to the internal validation dataset, with AUCs of 0.628 and 0.650, respectively. CONCLUSIONS We demonstrated that low levels of maternal serum PAPP-A and PlGF in the first trimester are associated with increased risks of sPTB and PPROM at < 37 weeks. However, further research is needed to identify additional biomarkers to improve the screening performance of the combined model that includes maternal risk factors, PAPP-A and PlGF before clinical application. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Background Taraxacum mongolicum (TM) is a widely used herb. Studies have reported that TM exhibits growth-inhibitory and apoptosis-inducing on multiple tumors, including hepatocellular carcinoma (HCC). The active ingredients, targets, and molecular mechanisms of TM against HCC need to be further elucidated. Methods We identified the active ingredients and targets of TM via HERB, PubChem, SwissADME, SwissTargetPrediction, and PharmMapper. We searched HCC targets from GeneCards, Comparative Toxicogenomics Database (CTD), and DisGeNET. Then, the intersection of drug targets and disease targets was uploaded to the STRING database to construct protein-protein interactions (PPI) networking whose topology parameters were analyzed in Cytoscape software to screen hub targets. Next, we used Metascape for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, and we employed AutoDock vina, AMBER18 and PyMOL software along with several auxiliary tools for molecular docking and molecular dynamics (MD) simulation. Finally, based on the in silico findings, cellular experiments were conducted to investigate the effect of TM on HSP90AA1 gene expression. Results A total of 228 targets and 35 active ingredients were identified. Twenty two hub targets were selected through PPI networking construction for further investigation. The enrichment analysis showed that protein kinase binding, mitogenactivated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathways were mainly involved. Molecular docking and MD simulation results supported good interaction between HSP90 protein and Austricin/Quercetin. The in vitro assay showed that TM inhibited the proliferation of HepG2 cells and the expression of HSP90AA1 gene. Conclusions This study is the first to use network pharmacology, molecular docking, MD simulation and cellular experiments to elucidate the active ingredients, molecular targets, and key biological pathways responsible for TM anti-HCC, providing a theoretical basis for further research.

Abstract
Liver fibrosis is a leading contributor to chronic liver diseases such as cirrhosis and liver cancer, which pose a serious health threat worldwide, and there are no effective drugs to treat it. Qijia Rougan decoction was modified from Sanjiasan, a traditional Chinese medicine (TCM) described in the “Wenyilun” manuscript. Qijia Rougan decoction possesses hepatoprotective and antifibrotic effects for clinical applications. However, its underlying mechanisms remain largely unknown. In this study, fibrotic rats induced by carbon tetrachloride (CCl4) were treated with two doses of Qijia Rougan decoction. Histopathological and serum biochemical analyses were carried out to assess liver structure and function, respectively. High-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS) was performed to identify bioactive compositions in Qijia Rougan decoction. Transcriptome analysis using mRNA-sequencing (mRNA-Seq) was used to explore the underlying mechanisms and verified by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. Qijia Rougan decoction significantly attenuated CCl4-induced hepatic fibrotic injury, supported by promoted liver function and improved liver fibrosis. Eight main representative components originating from raw materials in the Qijia Rougan decoction were found to possess an antifibrotic role. Mechanistically, Qijia Rougan decoction regulated biological processes such as oxidation–reduction, fatty acid metabolism, cell adhesion, and transforming growth factor beta (TGFβ) signaling. We determined that Qijia Rougan decoction reversed the expression of inflammatory cytokines and inhibited the activation of fibrosis-related TGFβ signaling. It also reversed the deterioration of liver structure and function in rats induced by CCl4. Overall, Qijia Rougan decoction significantly mediated metabolism-associated processes, inhibited inflammatory reactions, and repressed fibrosis-related TGFβ signaling, which prevented liver fibrosis deterioration. Our study deepens our understanding of TCM in the diagnosis and treatment of liver fibrosis.

Abstract
A paradigm shift in the physics of laser-plasma interactions is approaching with the commissioning of multipetawatt laser facilities worldwide. Radiation reaction processes will result in the onset of electron-positron pair cascades and, with that, the absorption and partitioning of the incident laser energy, as well as the energy transport throughout the irradiated targets. To accurately quantify these effects, one must know the focused intensity on target in situ. In this work, a way of measuring the focused intensity on target is proposed based upon the ionization of xenon gas at low ambient pressure. The field ionization rates from two works [Phys. Rev. A 59, 569 (1999)1050-294710.1103/PhysRevA.59.569 and Phys. Rev. A 98, 043407 (2018)2469-992610.1103/PhysRevA.98.043407], where the latter rate has been derived using quantum mechanics, have been implemented in the particle-in-cell code SMILEI [Comput. Phys. Commun. 222, 351 (2018)0010-465510.1016/j.cpc.2017.09.024]. A series of one- and two-dimensional simulations are compared and shown to reproduce the charge states without presenting visible differences when increasing the simulation dimensionality. They provide a way to accurately verify the intensity on target using in situ measurements.

Abstract
Volume dynamics is a two-compartment dynamical model using hemoglobin (Hb) derived plasma diluted level as input data and urine output as input variable through consecutive repeated measurements of Hb concentration in the blood during infusion. It could be applied to evaluate and guide crystalloid fluid rehydration for patients with dehydration or hypovolemia and during anesthesia or surgery. Volume dynamics could be also used to quantificate of strains, hypovolume, and the change of fluid distribution and elimination caused by anesthesia or surgery. The factors which influence the volume resuscitation are complex, including gender, age, hemodynamic state [mean arterial pressure (MAP)], health and stress state, renal function, consciousness, surgical or anesthesia state and so on, which may affect the half-life, distribution, and volume of the fluid. This article summarizes and analyzes the pathophysiological changes of crystalloids fluid in vivo, in order to provide reference for volume management in critically ill patients.

Lag periods of therapeutic efficacy cause poor compliance of patients, which has made solutions for rapid antidepressants the most urgent need in the depression study field at present. We have identified through our previous studies the rapid antidepressant effects of the traditional herb Gardenia jasminoides J.Ellis [Rubiaceae] (GJ) and its standardized fractions. Through screening different fractions of GJ, we decided to place our focus on the iridoid fraction of GJ (GJ-IF). Methods: 1. Tail suspension test (TST), forced swimming test (FST), and novelty suppressed-feeding test (NSFT) were performed in sequence on mice after GJ-IF administration. 2. Mice in the model group were under chronic unpredictable mild stress (CUMS) for 3 w. After GJ-IF treatment, mice were placed in an open field test (OFT), Sucrose preference test (SPT), NSFT, TST, and FST. 3. Western Blot was performed to examine the expression of brain-derived neurotrophic factor (BDNF), Synapsin 1, cyclic-AMP dependent protein kinase A (PKA), phosphorylated cyclic-AMP responsive element-binding protein (p-CREB), and cAMP response element-binding protein (CREB). 4. Mice in the test group were administrated with GJ-IF after intraperitoneal injection of PKA blocker H89. Results: 1. GJ-IF treatment significantly reduced the immobility time of TST at 1 d and FST at 26 h. 2. GJ-IF reversed the deficits induced by 3 w CUMS in SPT, TST, FST, and NSFT at 1 d and 26 h. The antidepressant effects of a single dose of iridoid fraction could also last for at least 14 d. 3. The results of molecule studies suggested that a single dose of GJ-IF activated p-CREB at 2 h and the PKA-CREB pathway at 1 d. The expression of BDNF did not significantly change from 30 min to 1 d after GJ-IF administration. 4. Blockade of PKA-CREB signaling pathway reversed the antidepressant effects of GJ-IF at 1 d, but not 30 min and 2 h. Conclusion: GJ-IF is the crucial component in the rapid antidepressant of GJ. Rapid and sustained antidepressant effects of GJ-IF were dependent on activating the PKA-CREB signaling pathway.

Abstract
Objectives: To clarify the effect of initial periodontal therapy on the dynamic changes of oral (saliva, dorsal tongue and subgingival plaque) microbiota in periodontitis patients with or without type 2 diabetes mellitus (T2DM). Methods: A total of 14 patients with chronic periodontitis (CP group) and 14 CP patients with T2DM (CP-T2DM group) were included from Department of Periodontology, School and Hospital of Stomatology,Cheeloo College of Medicine, Shandong University. The microbial samples were collected from saliva, dorsal tongue and subgingival plaque of first molars at baseline, 1.5 and 3 months after initial periodontal therapy, and were detected by 16S rRNA (V3-V4 region) gene sequencing. The sequencing data were analyzed to obtain microbial distribution and community structure information. The same professional periodontist evaluated the periodontal status of patients according to periodontitis detection indices before and after initial periodontal therapy. Meanwhile, patients' blood samples were collected and related metabolic indices were evaluated. Results: After initial periodontal therapy, the glycosylated hemoglobin levels [(7.46±1.69)%] in CP-T2DM group were significantly improved than that at baseline [(7.65±1.34)%] (t=0.52,P=0.610). The probing depth of the sampling sites [CP group: (2.94±0.46) mm, CP-T2DM group: (2.95±0.35) mm] and bleeding index (CP group: 1.91±0.42, CP-T2DM group: 1.67±0.49) at 3 months after treatment were significantly decreased than the probing depth [CP group: (3.99±0.77) mm, CP-T2DM group: (3.80±0.76) mm] (F=25.61, P<0.001; F=17.63, P<0.001) and bleeding index (CP group: 3.03±0.52, CP-T2DM group: 2.54±0.65) (F=28.43, P<0.001; F=20.21, P<0.001) at baseline. The flora analysis showed that the α and β diversity indices of the same sites in the CP and CP-T2DM groups did not change significantly before and after the initial therapy, but the bacterial abundance at each site changed. There were commonalities and differences in the microbial composition of each site in the CP and CP-T2DM groups. Among them, the relative abundance of Proteobacteria in saliva and dorsal tongue samples of the two groups after treatment was basically consistent with the change trend in the subgingival plaque microbes. In the subgingival plaque of the CP group, the relative abundance of Proteobacteria showed a gradual increase with the prolongation of initial periodontal therapy; while in the CP-T2DM group, it showed a trend of first increase and then decrease. Syntrophy, Dethiosulfate, Methanobacteriaceae and TG5 in CP and CP-T2DM groups were all significantly dominant bacteria in subgingival plaque at baseline (P<0.05). Moreover, in the CP-T2DM group Spirochetes also showed a significant advantage. At 1.5 months after treatment, Rhizobacteria, Alcaligenes, Comamomons, Delftia, Blautella, etc. were dominant in subgingival plaque (P<0.05). Firmicutes, Clostridia/Clostridiales, Enterococci and Ruminococci showed significant differences at 3 months (P<0.05). Conclusions: Plaques in saliva and tongue dorsal could reflect the effects of initial periodontal therapy on the dynamic changes of microorganisms to a certain extent. CP and CP-T2DM patients had differences in microbial composition and responses to initial periodontal therapy.

Abstract
BackgroundAzathioprine is a widely used immunosuppressant for the treatment of inflammatory conditions such as systemic lupus erythematosus (SLE), systemic vasculitis, dermatomyositis, and inflammatory bowel disease. However, its use is often limited by myelotoxicity. Variants in the gene encoding thiopurine-S-methyltransferase (TPMT), an enzyme in the metabolic pathway of azathioprine, increase the risk for myelotoxicity1. We know little about the relationship between the genetically predicted expression of TPMT and side effects of azathioprine.ObjectivesTo examine whether genetically predicted expression of TPMT in liver tissue is associated with azathioprine adverse effects.MethodsWe assembled a retrospective cohort of new users taking azathioprine for inflammatory conditions at a tertiary care center. We performed genotyping with Illumina Infinium Expanded Multi-Ethnic Genotyping Array plus custom content data, and we then used Michigan Imputation servers for genetic imputation and PrediXcan models trained with GTEx/Genotype-Tissue Expression Project version 8 data to impute TPMT expression in liver tissue. We prespecified nine groups of phecodes (comprised of ICD9 and ICD10 codes) corresponding to known adverse effects of azathioprine. We then tested the association between the predicted expression of TPMT and these adverse events; for outcomes significant in the Wilcoxon ranksum tests (p<0.05), each case was reviewed in clinical records for confirmation. Finally, we grouped the predicted expression of TPMT in liver tissue into tertiles and conducted logistic regressions to assess the associations between predicted expression and side effects. We conducted a sensitivity analysis restricted to patients with EHR-reported White race.ResultsThe cohort included 1034 patients (Table 1). Phecodes for 3 side effects—leukopenia (n=29), skin cancer (n=13), and rash (n=52)—were identified as associated with predicted TPMT expression in liver tissue. Of these, cases of side effects attributed to azathioprine were validated by chart review: leukopenia (96.6%; n=28), skin cancer (92.3%; n=12), and rash (9.6%; n=5) and used for analysis. When assessed by tertile of predicted TPMT expression, patients in the highest tertile had lower odds of having leukopenia (OR=0.35, 95%CI: 0.12-0.98, p=0.045) and a trend towards higher odds for skin cancer, but the number of cases was small (OR=3.56, 95%CI: 0.73-17.27, p=0.115). Confirmed cases of rash attributed to azathioprine were too few for meaningful analysis. We found similar results when restricted to patients with reported White race.Table 1.Characteristics of patients by TPMT expressionLowest TertileMiddle TertileHighest TertileN=345N=345N=344Female sex, n (%)228 (66.1)244 (70.7)238 (69.2)EHR-reported White race, n (%)306 (88.7)293 (84.9)290 (84.3)Age, median [IQR]42 [29-58]43 [30-55]46 [30-56]Indication, n (%)Systemic lupus erythematosus38 (11.0)42 (12.2)38 (11.0)Inflammatory bowel disease191 (55.3)185 (53.6)190 (55.2)Other connective tissue disorder/autoimmune92 (26.7)96 (27.8)100 (29.1)Other24 (7.0)22 (6.4)16 (4.7)Verified leukopenia attributed to azathioprine, n (%)14 (4.1)9 (2.6)5 (1.5)Verified skin cancer attributed to azathioprine, n (%)2 (0.6)3 (0.9)7 (2.0)Verified rash attributed to azathioprine, n (%)2 (0.6)3 (0.9)0 (0)ConclusionThis analysis suggests that PrediXcan may be useful for examining the association between gene expression and side effects of medications. Moreover, this approach successfully identified leukopenia as a side effect associated with predicted TPMT expression.AcknowledgementsNone to declare.Disclosure of InterestsNone declared.

Abstract
BackgroundAzathioprine (AZA) is a thiopurine immunosuppressant medication used to treat a variety of immune-mediated diseases. Unfortunately, its use is limited by adverse effects. Pancreatitis, a potentially severe, life-threatening side effect is independent of dose and necessitates AZA discontinuation given the high risk of recurrent pancreatitis with continued use or re-challenge. The mechanisms driving pancreatitis are unclear. While classic thiopurine-induced acute pancreatitis (TIAP) has been associated with HLA haplotypes, most patients taking AZA and presenting with pancreatitis do not fulfill the stringent criteria for TIAP.ObjectivesTo identify genetic risk factors for pancreatitis in patients taking azathioprine for immune-mediated conditions.MethodsUsing a biobank linked to electronic health records (EHR) from a tertiary center, we identified new users of AZA. Patients were excluded if the primary indication for AZA was organ transplant or if there was a history of pancreatitis prior to AZA use. The analysis was restricted to patients with EHR-reported race as White due to insufficient case counts for the non-White group. We then identified patients with amylase or lipase values that exceeded twice the upper limit of normal (“>2x ULN”) or with ICD-9/ICD-10 codes for acute pancreatitis. Each record was manually reviewed to confirm the timing of AZA use in relation to laboratory derangements or ICD coding, as well as to further classify patients into three increasingly strict, but not exclusive categories: 1) pancreatic injury (amylase or lipase >2x ULN); 2) acute pancreatitis1, or 3) TIAP2. We completed genotyping with Illumina Infinium Expanded Multi-Ethnic Genotyping Array plus custom content data, employed Michigan Imputation servers for genetic imputation, and used PrediXcan (GTEx v8) to impute gene expression. We then conducted genome-wide association and transcriptome-wide association studies (GWAS, TWAS). Acknowledging the relatively small overall cohort, and possible imbalance of cases vs controls, we used the Firth logistic regression method, which is a penalized likelihood-based method.ResultsWe studied 2127 AZA users (35.4% male; mean 44.5+/-17.2 years). The median AZA dose was 100mg/day (IQR: 50-125mg/day). Rheumatologic conditions (56.9%) and inflammatory bowel disease (40.4%) comprised the most common primary indications for AZA. Pancreatic injury, pancreatitis, and TIAP were diagnosed in 42 (2.0%), 16 (0.8%), and 9 (0.4%) patients, respectively. GWAS identified several significantly associated genes, many with overlapping TWAS findings in the pancreas and liver (Figure 1). From these, the two protein-encoding genes Fms Related Receptor Tyrosine Kinase-1 (FLT1) and Ephrin type-B receptor-2 (EPHB2) overlapped in two or more pancreatitis phenotypes in the TWAS and GWAS, respectively. EPHB2 was associated with a 8.6-fold (P=1.84 x 10-8) and a 31.4-fold (P=2.87x 10-8) higher likelihood of pancreatic injury and TIAP, respectively.Figure 1.ConclusionFLT1—a gene that encodes a receptor tyrosine kinase and is a member of the vascular endothelial growth factor receptor (VEGFR) family—and EPHB2—a gene that encodes a member of the Eph receptor family, which is the largest subgroup of the receptor tyrosine kinase family—are novel genetic markers associated with pancreatitis in patients taking AZA. VEGF can potentiate inflammation and the pancreas microenvironment is known to promote VEGF expression, which has been linked to pancreatic cancer development; anti-VEGF treatments have been investigated both for mitigating inflammation and also anti-pancreatic cancer treatment. Future studies validating our findings in AZA-induced pancreatitis are warranted.References[1]Crockett et al. Gastroenterology (2018). 154(4):1096-1101.[2]Heap et al.

Abstract
OBJECTIVE To analyze the epidemiological and clinical characteristics of patients infected by novel coronavirus Omicron variant, and also to analyze whether vaccination against novel coronavirus has an impact on the severity and prognosis of Omicron patients. METHODS A prospective, single-center observational study was conducted to collect data of consecutive patients with Omicron variant infection admitted to the designated hospital for coronavirus disease 2019 (COVID-19) charged by Tianjin COVID-19 rescue medical team of Tianjin Third Central Hospital, from January 8 to February 2, 2022. The clinical characteristics of the patients were analyzed, and the influence of whether the patients were inoculated with booster vaccination on the condition and outcome was analyzed. Data were collected including epidemiological, clinical features, laboratory and imaging examination, treatment measures and clinical outcomes, and difference between groups was analyzed. RESULTS A total of 362 patients were included, including 136 cases (37.57%) in the booster group, 190 cases (52.49%) in the routine vaccination group, and 36 cases (9.94%) in the unvaccinated group. There was a trend of concentrated distribution of patients, of which 171 cases (47.24%) patients showed family clustering, involving 69 families. Seventy-four cases (20.44%) of the 362 patients had one or more underlying diseases, mainly hypertension (64 cases, 17.68%), diabetes mellitus (23 cases, 6.35%), and coronary heart disease (18 cases, 4.97%); 215 patients (59.39%) had one or more discomfort symptoms, mainly cough (158 cases, 43.65%), pharyngeal discomfort (154 cases, 42.54%) and fever (136 cases, 37.57%). The diagnostic typing was mild type in 194 cases (53.59%), moderate type in 165 cases (45.58%) and severe type in 3 cases (0.83%). The patients had elevated immunoglobulin G (IgG) antibody titers to the novel coronavirus on admission [23.17 (3.08, 60.77)]. Patients were medically isolated and the main treatment measures included traditional Chinese medicine identification (Chinese medicine or tonics) in 265 cases (73.20%), prone treatment in 188 cases (51.93%), anticoagulation with low-molecular heparin in 106 cases (29.28%), immunomodulatory therapy with thymofacine in 21 cases (5.80%), antimicrobial drugs in 20 cases (5.52%), transnasal high-flow oxygen therapy in 12 cases (3.31%), glucocorticoids in 5 cases (1.38%), non-invasive mechanical ventilation in 1 case (0.28%), and invasive mechanical ventilation in 1 case (0.28%). A total of 362 patients were discharged with no deaths, of which 12 patients (3.31%) were admitted to the intensive care unit (ICU). The median duration of illness was 13 (10, 15) days, the median length of hospitalization was 13 (11, 15) days, and the median time to nucleic acid conversion was 13 (10, 15) days. Compared with the unvaccinated group, the IgG antibody titers of patients in the booster and routine vaccination groups [41.49 (20.32, 81.38), 19.94 (2.33, 49.25) vs. 0.16 (0.07, 1.94)] and the proportion of mild patients [66.91% (91/136), 48.94% (93/190) vs. 27.28% (10/36)] were higher, which were also higher in the booster vaccination group than in the conventional vaccination group (all P < 0.05). Compared to the conventional and booster vaccination groups, the unvaccinated group had a higher proportion of severe patients [5.56% (2/36) vs. 0.53% (1/190), 0 (1/136)], longer time to nucleic acid conversion [days: 15 (11, 16) vs.12 (10, 15), 13 (11, 15)], and longer disease duration [days: 15 (11, 16) vs. 12 (10, 15), 13 (11, 15)], and a higher percentage of ICU admissions [16.67% (6/36) vs. 2.63% (5/190), 0.74% (1/136)], with statistically significant differences among the three groups (all P < 0.05). CONCLUSIONS Omicron variant is extremely infectious with aggregated onset, but its clinical symptoms are mild. The vaccine, especially the booster vaccination, remains effective in preventing severe-stage progression and improving prognosis in patients with Omicron variant infection.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has been renamed metabolic dysfunction-associated fatty liver disease (MAFLD), a condition for which there is now no authorized treatment. The search for new medications to treat MAFLD made from natural substances is gaining traction. The function of anti-oxidant, anti-inflammation, hypoglycaemic, antiviral, hypolipidemic, and immunomodulatory actions of Astragalus polysaccharides (APS), a chemical molecule isolated from Astragalus membranaceus, has become the focus of therapeutic attention. We have a large number of papers on the pharmacological effects of APS on NAFLD that have never been systematically reviewed before. According to our findings, APS may help to slow the progression of non-alcoholic fatty liver disease (NAFL) to non-alcoholic steatohepatitis (NASH). Lipid metabolism, insulin resistance (IR), oxidative stress (OS), endoplasmic reticulum stress (ERS), inflammation, fibrosis, autophagy, and apoptosis are some of the pathogenic pathways involved. SIRT1/PPARα/FGF21, PI3K/AKT/IRS-1, AMPK/ACC, mTOR/4EBP-1/S6K1, GRP78/IRE-1/JNK, AMPK/PGC-1/NRF1, TLR4/MyD88/NF-κB, and TGF-β/Smad pathways were the most common molecular protective mechanisms. All of the information presented in this review suggests that APS is a natural medication with a lot of promise for NAFLD, but more study, bioavailability studies, medicine type and dosage, and clinical proof are needed. This review could be useful for basic research, pharmacological development, and therapeutic applications of APS in the management of MAFLD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fuzheng Xiaozheng prescription (FZXZP) is a traditional Chinese medicine (TCM) that was derived from Sanjiasan, a famous decoction documented in the book of Wenyilun in Ming dynasty. Based on our years' clinic application, FZXZP demonstrated satisfactory therapeutic effects in cirrhosis and hepatocellular carcinoma (HCC) treatments. However, the underlying mechanisms are still largely unknown. AIM OF STUDY In this study, we aim to systematically evaluate the intervention effects of FZXZP on rat HCC and deeply elucidate the underlying regulative mechanisms on rat HCC. MATERIALS AND METHODS The HCC rats were induced by using diethylnitrosamine (DEN) and two doses of FZXZP were adopted to treat the HCC rats. Liver phenotype, blood chemistry and liver histopathology were used to evaluate the intervention effects. High performance liquid chromatography (HPLC) was conducted to analyze the components of FZXZP. Finally, miRNA-Seq and mRNA-Seq were performed to investigate the regulative mechanisms of FZXZP on rat HCC and qRT-PCR was carried out to verify the accuracies of the two RNA-Seqs. RESULTS Results of liver phenotypes, blood chemistry and liver histopathology demonstrated that FZXZP significantly alleviated the liver damage, inhibited the progresses of HCC. Nine potential components were identified from FZXZP, and anti-cancer prediction suggested that almost all of them were reported to show an anti-cancer effect. Mechanistically, FZXZP was found to promote the lipid related metabolisms, improve the anti-inflammation ability by activating PPAR signaling pathway, arachidonic acid metabolism, bile secretion, etc. CONCLUSION: our results suggested that FZXZP significantly alleviated the rat HCC, mechanistically by improving the anti-inflammation ability and promoting the lipid related metabolisms.

Abstract
Proton radiography is a widely fielded diagnostic used to measure magnetic structures in plasma. The deflection of protons with multi-MeV kinetic energy by the magnetic fields is used to infer their path-integrated field strength. Here the use of tomographic methods is proposed for the first time to lift the degeneracy inherent in these path-integrated measurements, allowing full reconstruction of spatially resolved magnetic field structures in three dimensions. Two techniques are proposed which improve the performance of tomographic reconstruction algorithms in cases with severely limited numbers of available probe beams, as is the case in laser-plasma interaction experiments where the probes are created by short, high-power laser pulse irradiation of secondary foil targets. A new configuration allowing production of more proton beams from a single short laser pulse is also presented and proposed for use in tandem with these analytical advancements.

Abstract
BACKGROUND The pathogenesis of human immunodeficiency virus 1 (HIV-1) infection is so complex that have not been clearly defined, despite intensive efforts have been made by many researchers. MicroRNA (miRNA) as regulation factor in various human diseases may influence the course of HIV-1 infection by targeting mRNAs. Thus, studies combining transcription of posttranscriptional miRNA regulation are required. METHODS With the purpose of identifying cascaded miRNA-mRNA regulatory relationships related to HIV infection in gene level, the parallel miRNA, and mRNA expression profiles were analyzed to select differential expressed miRNAs and mRNAs. Then, miRNA-mRNA interactions were predicted using 3 data sources and Pearson correlation coefficient was calculated based on the gene expression level for accuracy improvement. Furthermore, the calculation of the regulatory impact factors was conducted to reveal crucial regulators in HIV-1 infection. To give further insight into these transcription factor (TF) regulators, the differentially co-expression analysis was conducted to identify differentially co-expressed links and differential co-expressed genes and the co-expression gene modules were identified using a threshold-based hierarchical clustering method, then modules were combined into a miRNA-TF-mRNA network. RESULTS A total of 69,126 differentially co-expressed links and 626 differential co-expressed genes were identified. Functional enrichment analysis indicated that these co-expressed genes were significantly involved in immune response and apoptosis. Moreover, according to regulatory impact factors, 5 most influential TFs and miRNA in HIV-1 infection were identified and miRNA-TF-mRNA regulatory networks were built during the computing process. CONCLUSIONS In our study, a set of integrated methods was generated to identify important regulators and miRNA-TF-mRNA interactions. Parallel profiling analysis of the miRNAs and mRNAs expression of HIV/acquired immunodeficiency syndrome (AIDS) patients after antiretroviral therapy indicated that some regulators have wide impact on gene regulation and that these regulatory elements may bear significant implications on the underlying molecular mechanism and pathogenesis of AIDS occurrence.

Abstract
Objective: Contrast-enhanced CT is an important method of preoperative diagnosis and evaluation for the malignant potential of gastric submucosal tumor (SMT). It has a high diagnostic accuracy rate in differentiating gastric gastrointestinal stromal tumor (GIST) with a diameter greater than 5 cm from gastric benign SMT. This study aimed to use deep learning algorithms to establish a diagnosis model (GISTNet) based on contrast-enhanced CT and evaluate its diagnostic value in distinguishing gastric GIST with a diameter ≤ 5 cm and other gastric SMT before surgery. Methods: A diagnostic test study was carried out. Clinicopathological data of 181 patients undergoing resection with postoperative pathological diagnosis of gastric SMT with a diameter ≤ 5 cm at Department of Gastrointestinal Surgery of Renji Hospital from September 2016 to April 2021 were retrospectively collected. After excluding 13 patients without preoperative CT or with poor CT imaging quality, a total of 168 patients were enrolled in this study, of whom, 107 were GIST while 61 were benign SMT (non-GIST), including 27 leiomyomas, 24 schwannomas, 6 heterotopic pancreas and 4 lipomas. Inclusion criteria were as follows: (1) gastric SMT was diagnosed by contrast-enhanced CT before surgery; (2) preoperative gastroscopic examination and biopsy showed no abnormal cells; (3) complete clinical and pathological data. Exclusion criteria were as follows: (1) patients received anti-tumor therapy before surgery; (2) without preoperative CT or with poor CT imaging quality due to any reason; (3) except GIST, other gastric malignant tumors were pathologically diagnosed after surgery. Based on the hold-out method, 148 patients were randomly selected as the training set and 20 patients as the test set of the GISTNet diagnosis model. After the GISTNet model was established, 5 indicators were used for evaluation in the test set, including sensitivity, specificity, positive predictive value, negative predictive value and the area under the receiver operating curve (AUC). Then GISTNet diagnosis model was compared with the GIST-risk scoring model based on traditional CT features. Besides, in order to compare the accuracy of the GISTNet diagnosis model and the imaging doctors in the diagnosis of gastric SMT imaging, 3 radiologists with 3, 9 and 19 years of work experience, respectively, blinded to clinical and pathological information, tested and judged the samples. The accuracy rate between the three doctors and the GISTNet model was compared. Results: The GISTNet model yielded an AUC of 0.900 (95% CI: 0.827-0.973) in the test set. When the threshold value was 0.345, the sensitivity specificity, positive and negative predictive values of the GISTNet diagnosis model was 100%, 67%, 75% and 100%, respectively. The accuracy rate of the GISTNet diagnosis model was better than that of the GIST-risk model and the manual readings from two radiologists with 3 years and 9 years of work experience (83% vs. 75%, 60%, 65%), and was close to the manual reading of the radiologist with 19 years of work experience (83% vs. 80%). Conclusion: The deep learning algorithm based on contrast-enhanced CT has favorable and reliable diagnostic accuracy in distinguishing gastric GIST with a diameter ≤ 5 cm and other gastric SMT before operation.

Abstract
OBJECTIVE To investigate the clinical effect of setting proportional pressure support (PPS) parameters by target tidal volume (VT) method. METHODS The study was conducted retrospectively on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients admitted to Tianjin Third Central Hospital from January 2016 to December 2020. According to the PPS parameter setting method, the patients were divided into the airway blocking group and target VT group. The baseline characteristics, initial setting values of flow assist (FA) and volume assist (VA), respiratory system parameters, and clinical outcomes were collected and compared between the two groups. RESULTS Fifty-nine patients were enrolled, 29 patients in the airway blocking group, and 30 in the target VT group. There was no statistically significant difference in baseline characteristics, compliance, resistance, and initial settings of FA and VA between the two groups. Compared with the target VT group, the respiratory rate (RR), mean arterial pressure (MAP), VT, and arterial partial pressure of oxygen (PaO2) recorded 1 hour after the initial setting of the PPS parameters in the airway block method group were significantly reduced [RR (times/minute): 21.0 (18.5, 22.5) vs. 23.0 (21.0, 25.0), MAP (mmHg, 1 mmHg = 0.133 kPa): 84.0 (79.0, 90.5) vs. 90.0 (87.0, 96.2), VT (mL): 305.24±41.07 vs. 330.87±46.84, PaO2 (mmHg): 68.0 (66.0, 73.5) vs. 74.0 (69.8, 82.5), all P < 0.05], while arterial partial pressure of carbon dioxide (PaCO2) and oral closure pressure (P0.1) were both increased significantly [PaCO2 (mmHg): 41.0 (39.0, 46.0) vs. 37.5 (35.0, 42.2), P0.1 (cmH2O, 1 cmH2O = 0.098 kPa): 1.42±0.78 vs. 0.90±0.67, both P < 0.05]. Compared with airway blocking group, the duration of weaning, ICU stay, and hospital stay in the target VT group were significantly shorter [duration of weaning (hours): 42.0 (24.0, 70.5) vs. 64.0 (30.5, 97.5), ICU stay: 10.00±3.38 to 13.28±5.41, hospital stay (days): 12.07±3.40 vs. 15.41±5.60, all P < 0.05]. There was no statistically significant difference in the invasive mechanical ventilation time, weaning failure rate, ICU mortality and in-hospital mortality between the two groups. CONCLUSIONS This study suggested that the target TV method has the advantages of practicality, safety, convenience, and rapid to set PPS parameters than the airway block method, which shortens the duration of weaning and ICU stay, and has a good clinical prospect.

Abstract
In this study, MicroRNA-210 (miR-210), which was previously proved to be a potential immunomodulator in various disease, attenuated mouse myocardium ischemia/reperfusion (I/R) injury. miR-210 was increased in cardiomyocytes exposed to hypoxia/reoxygenation (H/R). The expression of IL-6 and TNF-α in both serum and supernatant were reduced in miR-210 mimics groups. Mice were randomly divided into four groups, which were pre-treated with saline (sham and ischemia/reperfusion group), miR-210 mimics and miR-210 inhibitor treatments. Three days later, the mouse IR model was established by ischemia for 30 min, followed by reperfusion for 3 h. Myocardium and plasma were harvested and assessed. The myocardium histopathological changes were reduced in miR-210 mimics groups, and serum levels of Creatine kinase isoenzyme (CK-MB) and Lactate dehydrogenase (LDH) were significantly decreased compared with I/R groups. The protein expression of proinflammatory factor interleukin (IL)-1β and IL-6 were suppressed by the up-regulation of miR-210. The expression of miR-210 was negatively correlated with the expression of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB). In conclusion, our study indicates that miR-210 protects heart from myocardium I/R injury via suppressing NF-κB signal pathway.

Abstract
OBJECTIVE To analyze the possible causes of arrhythmia in patients receiving continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA). METHODS A retrospective cohort study was conducted. All patients underwent RCA-CRRT treatment from January 1, 2020 to October 31, 2020 in the intensive care unit (ICU) of Tianjin Third Central Hospital were enrolled. The patients were divided into arrhythmia group and non-arrhythmia group according to whether arrhythmia occurred. The gender, age, acute physiology and chronic health evaluation II (APACHE II) score, catheterization site, underlying diseases, electrocardiogram (ECG), electrolytes [total calcium, serum free calcium (iCa2+), phosphorus, magnesium, potassium] and blood gas analysis (pH value, HCO3-) of patients in the two groups were recorded. The changes of ECG were observed, the differences in electrolyte and blood gas analysis indexes between the two groups of patients at different time points (before CRRT, 24, 48, 72 hours after CRRT, and when arrhythmia occurred) were compared. RESULTS A total of 86 RCA-CRRT patients were enrolled, of which 12 cases (13.95%) had arrhythmia, and the remaining 74 cases (86.05%) had no arrhythmia. The average time for the occurrence of arrhythmia in the 12 patients was (44.00±16.82) hours. There was no significant ST-segment change in the ECG when the arrhythmia occurred compared with that before CRRT, the total calcium level was significantly higher than that before CRRT (mmol/L: 2.48±0.40 vs. 2.13±0.35, P < 0.05), the blood magnesium level was significantly lower than that before CRRT (mmol/L: 0.73±0.20 vs. 0.95±0.25, P < 0.05). There was no significant difference in iCa2+, blood phosphorus, blood potassium, pH value and HCO3- between before CRRT and when arrhythmia occurred. Over time, the total calcium levels in the two groups increased, and there was a statistical difference between the 48 hours after CRRT and before CRRT (mmol/L: 2.48±0.33 vs. 2.13±0.35 in the arrhythmia group, and 2.30±0.22 vs. 2.15±0.48 in non-arrhythmia group, both P < 0.05). The linear change trend of iCa2+, pH value and HCO3- was not obvious in the two groups. The blood phosphorus and blood magnesium levels in the two groups decreased. The blood potassium in the arrhythmia group decreased, however, the blood potassium level in non-arrhythmia group did not change significantly. The total calcium level in the arrhythmia group was significantly higher than that in the non-arrhythmia group at 72 hours after CRRT (mmol/L: 2.69±0.35 vs. 2.45±0.23, P < 0.05); however, there was no significant difference in serum iCa2+, phosphorus, magnesium, potassium, pH value and HCO3- between the two groups. CONCLUSIONS Patients receiving RCA-CRRT were less likely to develop arrhythmia, the causes may be related to the accumulation of citric acid and electrolyte disturbances such as calcium, phosphorus, and magnesium.
