A Room-Temperature Self-Healing Liquid Metal-Infilled Microcapsule Driven by Coaxial Flow Focusing for High-Performance Lithium-Ion Battery Anode.

Liquid metals have attracted a lot of attention as self-healing materials in many fields. However, their applications in secondary batteries are challenged by electrode failure and side reactions due to the drastic volume changes during the "liquid-solid-liquid" transition. Herein, a simple encapsulated, mass-producible method is developed to prepare room-temperature liquid metal-infilled microcapsules (LMMs) with highly conductive carbon shells as anodes for lithium-ion batteries. Due to the reasonably designed voids in the microcapsule, the liquid metal particles (LMPs) can expand freely without damaging the electrode structure. The LMMs-based anodes exhibit superior capacity of rete-performance and ultra-long cycling stability remaining 413 mAh g-1 after 5000 cycles at 5.0 A g-1. Ex situ X-ray powder diffraction (XRD) patterns and electrochemical impedance spectroscopy (EIS) reveal that the LMMs anode displays a stable alloying/de-alloying mechanism. DFT calculations validate the electronic structure and stability of the room-temperature LMMs system. These findings will bring some new opportunities to develop high-performance battery systems.

Earth-Abundant CuWO4 as a Versatile Platform for Photoelectrochemical Valorization of Soluble Biomass Under Benign Conditions.

Here, a nanosheet-structured CuWO4 (nanoCuWO4) is demonstrated as a selective and stable photoanode for biomass valorization in neutral and near-neutral solutions. nanoCuWO4 can be readily prepared by a solid phase reaction using nanosheet-structured WO3 as the template. Several substrates, including glucose, fructose and glycerol, are investigated to reveal the wide applicability of nanoCuWO4. The activity and product distribution trends in biomass valorization are investigated at different pH by taking advantage of the promising stability of nanoCuWO4 in a wide pH range. Product analyses confirm that formate production with a Faradaic efficiency (FE) of 76 ± 5% and glycolate production with an FE of 61 ± 8% can be achieved by glucose and fructose valorization at pH 10.2, respectively. On the other hand, glyceraldehyde and dihydroxyacetone (DHA) are the main products in the glycerol valorization, accounting for an FE of over 85% at pH 7. Notably, nanoCuWO4 has the highest FE of DHA in photoelectrochemical (PEC) glycerol valorization compared to WO3 and BiVO4 at neutral pH. The oxidation routes and mechanism of glycerol valorization on nanoCuWO4 are also under investigation. The co-production of H2 and value-added chemicals is finally demonstrated using a photovoltaic cell connected to a nanoCuWO4-based PEC glycerol valorization system.

USP5: Comprehensive insights into structure, function, biological and disease-related implications, and emerging therapeutic opportunities.

Ubiquitin specific protease 5 (USP5) is a vital deubiquitinating enzyme that regulates various physiological functions by removing ubiquitin chains from target proteins. This review provides an overview of the structural and functional characteristics of USP5. Additionally, we discuss the role of USP5 in regulating diverse cellular processes, including cell proliferation, apoptosis, DNA double-strand damage, methylation, heat stress, and protein quality control, by targeting different substrates. Furthermore, we describe the involvement of USP5 in several pathological conditions such as tumors, pathological pain, developmental abnormalities, inflammatory diseases, and virus infection. Finally, we introduce newly developed inhibitors of USP5. In conclusion, investigating the novel functions and substrates of USP5, elucidating the underlying mechanisms of USP5-substrate interactions, intensifying the development of inhibitors, and exploring the upstream regulatory mechanisms of USP5 in detail can provide a new theoretical basis for the treatment of various diseases, including cancer, which is a promising research direction with considerable potential. Overall, USP5 plays a critical role in regulating various physiological and pathological processes, and investigating its novel functions and regulatory mechanisms may have significant implications for the development of therapeutic strategies for cancer and other diseases.

Vibrational energy relaxation in shock-heated CO/N2/Ar mixtures.

Experimental and numerical studies were performed on the vibrational energy relaxation in shock-heated CO/N2/Ar mixtures. A laser absorption technique was applied to the time-dependent rovibrational temperature time-history measurements. The vibrational relaxation data of reflected-shock-heated CO were summarized at 1720-3230 K. In shock-tube experiments, the rotational temperature of CO quickly reached equilibrium, whereas a relaxation process was found in the time-dependent vibrational temperature. For the mixture with 1.0% CO and 10.0% N2, the vibrational excitation caused a decrease in the macroscopic thermodynamic temperature of the test gas. In the simulations, the state-to-state (StS) approach was employed, where the vibrational energy levels of CO and N2 are treated as pseudo-species. The vibrational state-specific inelastic rate coefficients of N2-Ar collisions were calculated using the mixed quantum-classical method based on a newly developed three-dimensional potential energy surface. The StS predictions agreed well with the measurements, whereas deviations were found between the Schwartz-Slawsky-Herzfeld formula predictions and the measurements. The Millikan-White vibrational relaxation data of the N2-Ar system were found to have the most significant impact on the model predictions via sensitivity analysis. The vibrational relaxation data of the N2-Ar system were then modified according to the experimental data and StS results, providing an indirect way to optimize the vibrational relaxation data of a specific system. Moreover, the vibrational distribution functions of CO and N2 and the effects of the vibration-vibration-translation energy transfer path on the thermal nonequilibrium behaviors were highlighted.

Il34 rescues metronidazole-induced impairment of spinal cord regeneration in zebrafish central nervous system.

Metronidazole (MTZ), a commonly used anti-infective drug in clinical practice, has also been employed as a prodrug in cell-targeted ablation systems in scientific research, exhibiting significant application value. However, it has been demonstrated that MTZ can induce neurotoxic symptoms to some extent during its use, and there is currently a lack of effective means to circumvent its toxicity in both clinical and research settings, which limits its application. Therefore, exploring the specific mechanisms underlying MTZ-induced neurotoxic symptoms and elucidating countermeasures will enhance the practical value of MTZ. In this study, using a zebrafish spinal cord injury regeneration model, we confirmed that MTZ neurotoxicity leads to impaired axon regeneration in the central nervous system. By overexpressing il34 in the central nervous system of zebrafish, we eliminated the inhibitory effect of MTZ on axonal regeneration and demonstrated that the pro-regenerative effect against MTZ neurotoxicity is not caused by excessive macrophages/microglia chemoattracted by interleukin 34(Il34). Transcriptome sequencing analysis and GO enrichment analysis of differentially expressed genes between groups revealed that Il34 may counteract MTZ neurotoxicity and promote spinal cord injury repair through biological processes that enhance cellular adhesion and cell location. In summary, our work uncovers a possible cause of MTZ neurotoxicity and provides a new perspective for eliminating MTZ toxicity.

Exosomes derived from cardiac fibroblasts with angiotensin II stimulation provoke hypertrophy and autophagy inhibition in cardiomyocytes.

Although accumulating evidence has revealed that autophagy inhibition contributes to the development of pathological cardiac hypertrophy, the mechanisms leading to declined autophagy activity in the hypertrophic heart remain to be elucidated. Exosomes are known to be important mediators of intercellular communication, and the involvement of exosomes in cardiovascular abnormities has attracted increasing attentions. Cardiac fibroblasts (CFs) are the most abundant cell type in the heart. Here, we investigated the potential role of CFs-derived exosomes in regulating cardiomyocyte hypertrophy and autophagy. Exosomes from rat CFs treated with angiotensin II (Ang II-CFs-exosomes) were collected and characterized. Our experiments showed that these exosomes could induce hypertrophic responses and impair autophagy activity in primary neonatal rat cardiomyocytes (NRCMs). Ang II-CFs-exosomes blocked the autophagic flux of NRCMs via inhibiting the formation of autolysosomes. Moreover, the pro-hypertrophic effects and autophagy inhibition induced by Ang II-CFs-exosomes was validated in mice receiving injection of the exosomes. These findings highlight a novel role of Ang II-CFs-exosomes in suppressing cardiomyocyte autophagy, which may help to better understand the pathogenesis of cardiac hypertrophy.

Inhibition of miR-214-3p attenuates ferroptosis in myocardial infarction via regulating ME2.

Myocardial infarction (MI) contributes to an increased risk of incident heart failure and sudden death, but there is still a lack of effective treatment in clinic. Recently, growing evidence has indicated that abnormal expression of microRNAs (miRNAs) plays a crucial role in cardiovascular diseases. In this research, the involvement of miRNA-214-3p in MI was explored. A mouse model of MI was established by ligation of the left anterior descending coronary artery, and primary cultures of neonatal rat cardiomyocytes (NRCMs) were submitted to hypoxic treatment to stimulate cellular injury in vitro. Our results showed that miR-214-3p level was significantly upregulated in the infarcted region of mouse hearts and in NRCMs exposed to hypoxia, accompanying with an obvious elevation of ferroptosis. Inhibition of miR-214-3p by antagomir injection improved cardiac function, decreased infarct size, and attenuated iron accumulation and oxidant stress in myocardial tissues. MiR-214-3p could also promote ferroptosis and cellular impairments in NRCMs, while miR-214-3p inhibitor effectively protected cells from hypoxia. Furthermore, dual luciferase reporter gene assay revealed that malic enzyme 2 (ME2) is a direct target of miR-214-3p. In cardiomyocytes, overexpression of ME2 ameliorated the detrimental effects and excessive ferroptosis induced by miR-214-3p mimic, whereas ME2 depletion compromised the protective role of miR-214-3p inhibitor against hypoxic injury and ferroptosis. These findings suggest that miR-214-3p contributes to enhanced ferroptosis during MI at least partially via suppressing ME2. Inhibition of miR-214-3p may be a new approach for tackling MI.

Nalbuphine attenuates morphine-induced scratching by inhibiting PKCß-dependent microglial activation and p38 phosphorylation in male mice.

Morphine-induced scratching (MIS) is a common adverse effect associated with the use of morphine as analgesia after surgery. However, the treatment of MIS is less than satisfactory due to its unclear mechanism, which needs to be enunciated. We found that intrathecal (i.t.) injections of morphine significantly enhanced scratching behavior in C57BL/6J male mice as well as increased the expressions of protein kinase C ß (PKCß), phosphorylated p38 mitogen-activated protein kinases (MAPK), and ionized calcium-binding adapter molecule 1 (Iba1) within spinal cord dorsal horn. Conversely, using the kappa opioid receptor antagonist nalbuphine significantly attenuated scratching behavior, reduced PKCß expression and p38 phosphorylation, and decreased spinal dorsal horn microglial activation, while PKCδ and KOR expression elevated. Spinal PKCß silencing mitigated MIS and microglial activation. Still, knockdown of PKCδ reversed the inhibitory effect of nalbuphine on MIS and microglial activation, indicating that PKCδ is indispensable for the antipruritic effects of nalbuphine. In contrast, PKCß is crucial for inducing microglial activation in MIS in male mice. Our findings show a distinct itch cascade of morphine, PKCß/p38MAPK, and microglial activation, but an anti-MIS pathway of nalbuphine, PKCδ/KOR, and neuron activation.

High Expression of CD300A Predicts Poor Survival in Acute Myeloid Leukemia.

INTRODUCTION: Recent studies have suggested that CD300A was an oncogene in acute myeloid leukemia (AML) development. However, the clinical relevance and biological insight into CD300A expression in AML are still not well understood. The present study aimed to examine the expression characteristics of CD300A in AML and confirmed its clinical significance for AML. METHODS: Quantification of the CD300A transcript was performed in 119 AML patients by real-time quantitative PCR in bone marrow blasts. The predictive significance of CD300A expression on the clinical outcomes of AML was assessed using overall survival (OS) and relapse-free survival (RFS). The published Cancer Genome Atlas (TCGA) data were used as an external validation for survival analysis and pathway analyses. RESULTS: In comparison with monocytes from healthy peripheral blood cells, the expression levels of CD300A in AML cells were higher. Patients in the intermediate and adverse risk categories by WHO criteria (2018) had higher CD300A expression levels than those in the favorable risk category (p < 0.001). AML patients with high expression of CD300A had a higher early death rate (p = 0.029), lower complete remission rate (p = 0.042), higher death rate (p < 0.001) and relapse rate (p = 0.002), and shorter OS (p < 0.0001) and RFS (p < 0.0001). Through multivariable analysis, high CD300A expression in AML was also an independent poor prognostic factor. The CAMP and CGMP-PKG signaling pathways may be stimulated by increased CD300A expression levels, which may be important for the development of AML. CONCLUSIONS: The expression levels of CD300A were associated with risk stratification and the clinical relevance of AML. High CD300A expression may act as an independent adverse prognostic factor for OS and RFS in AML.

A prediction model for moderate to severe cancer-related fatigue in colorectal cancer after chemotherapy: a prospective case‒control study.

AIMS: The study aims to develop a model to predict the risk of moderate to severe cancer-related fatigue (CRF) in colorectal cancer patients after chemotherapy. METHODS: The study population was colorectal cancer patients who received chemotherapy from September 2021 to June 2022 in a grade 3 and first-class hospital. Demographic, clinical, physiological, psychological, and socioeconomic factors were collected 1 to 2 days before the start of chemotherapy. Patients were followed up for 1 to 2 days after the end of chemotherapy to assess fatigue using the Piper Fatigue Scale. A random sampling method was used to select 181 patients with moderate to severe CRF as the case group. The risk set sampling method was used to select 181 patients with mild or no CRF as the control group. Logistic regression, back-propagation artificial neural network (BP-ANN), and decision tree models were constructed and compared. RESULTS: A total of 362 patients consisting of 241 derivation samples and 121 validation samples were enrolled. Comparing the three models, the prediction effect of BP-ANN was the best, with a receiver operating characteristic (ROC) curve of 0.83. Internal and external verification indicated that the accuracy of prediction was 70.4% and 80.8%, respectively. Significant predictors identified were surgery, complications, hypokalaemia, albumin, neutrophil percentage, pain (VAS score), Activities of Daily Living (ADL) score, sleep quality (PSQI score), anxiety (HAD-A score), depression (HAD-D score), and nutrition (PG-SGA score). CONCLUSIONS: BP-ANN was the best model, offering theoretical guidance for clinicians to formulate a tool to identify patients at high risk of moderate to severe CRF.

Experimental and numerical studies on the thermal nonequilibrium behaviors of CO with Ar, He, and H2.

The time-dependent rotational and vibrational temperatures were measured to study the shock-heated thermal nonequilibrium behaviors of CO with Ar, He, and H2 as collision partners. Three interference-free transition lines in the fundamental vibrational band of CO were applied to the fast, in situ, and state-specific measurements. Vibrational relaxation times of CO were summarized over a temperature range of 1110-2820 K behind reflected shocks. The measured rotational temperature instantaneously reached an equilibrium state behind shock waves. The measured vibrational temperature experienced a relaxation process before reaching the equilibrium state. The measured vibrational temperature time histories were compared with predictions based on the Landau-Teller model and the state-to-state approach. The state-to-state approach treats the vibrational energy levels of CO as pseudo-species and accurately describes the detailed thermal nonequilibrium processes behind shock waves. The datasets of state-specific inelastic rate coefficients of CO-Ar, CO-He, CO-CO, and CO-H2 collisions were calculated in this study using the mixed quantum-classical method and the semiclassical forced harmonic oscillator model. The predictions based on the state-to-state approach agreed well with the measured data and nonequilibrium (non-Boltzmann) vibrational distributions were found in the post-shock regions, while the Landau-Teller model predicted slower vibrational temperature time histories than the measured data. Modifications were applied to the Millikan-White vibrational relaxation data of the CO-Ar and CO-H2 systems to improve the performance of the Landau-Teller model. In addition, the thermal nonequilibrium processes behind incident shocks, the acceleration effects of H2O on the relaxation process of CO, and the characterization of vibrational temperature were highlighted.

Ulinastatin inhibits the metastasis of nasopharyngeal carcinoma by involving uPA/uPAR signaling.

Distant metastasis is the primary reason for treatment failure in patients with nasopharyngeal carcinoma (NPC). In this study, we investigated the effect of ulinastatin (UTI) on NPC metastasis and its underlying mechanism. Highly-metastatic NPC cell lines S18 and 58F were treated with UTI and the effect on cell proliferation, migration, and invasion were determined by MTS and Transwell assays. S18 cells with luciferase-expressing (S18-1C3) were injected into the left hind footpad of nude mice to establish a model of spontaneous metastasis from the footpad to popliteal lymph node (LN). The luciferase messenger RNA (mRNA) was measured by quantitative polymerase chain reaction (qPCR), and the metastasis inhibition rate was calculated. Key molecular members of the UTI-related uPA, uPAR, and JAT/STAT3 signaling pathways were detected by qPCR and immunoblotting. UTI suppressed the migration and infiltration of S18 and 5-8F cells and suppressed the metastasis of S18 cells in vivo without affecting cell proliferation. uPAR expression decreased from 24 to 48 h after UTI treatment. The antimetastatic effect of UTI is partly due to the suppression of uPA and uPAR. UTI partially suppresses NPC metastasis by downregulating the expression of uPA and uPAR.

Effectiveness of prophylactic antiviral therapy in reducing HBV reactivation for HBsAg-positive recipients following allogeneic hematopoietic stem cell transplantation: a multi-institutional experience from an HBV endemic area.

Hepatitis B virus reactivation (HBVr) is not uncommon in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Hepatitis B surface antigen (HBsAg)-positive patients receiving allo-HSCT have a very high risk of HBVr. However, the validity of prophylactic antiviral treatment in HBsAg-positive allo-HSCT recipients has not been well studied. We aimed to add experience in dealing with HBsAg-positive patients following allo-HSCT. We conducted a cohort study that included 11 years of data of HBsAg-positive allo-HSCT patients in multiple centers. The cumulative incidence of HBVr with antiviral prophylaxis at 60 months following transplantation was 8.9%. Both lamivudine (LAM) and entecavir (ETV) effectively reduced the incidence of HBVr. Patients with absent-mild cGVHD had a lower HBVr rate than that of patients with moderate-severe cGVHD (HR = 0.201, P = 0.020). The incidence of HBsAg seroclearance at 60 months following transplantation was 34.3%. Recipients accepting from anti-HBs-negative donors were associated with a lower HBsAg seroclearance rate than that of those accepting from anti-HBs-positive donors (HR=0.255, P < 0.001). The peripheral blood stem cell (PBSC) donor source had a higher HBsAg seroclearance rates than that of the PBSC plus bone marrow stem cell source (HR = 4.700, P = 0.047). The prophylactic antiviral treatment effectively reduced HBVr in HBsAg-positive recipients receiving allo-HSCT. HBsAg-positive recipients accept anti-HBs-positive PBSC donor sources may facilitate the acquisition of HBsAg seroclearance after transplantation.

Effects of sleep interventions on cancer-related fatigue and quality of life in cancer patients: a systematic review and meta-analysis.

BACKGROUND: Nondrug treatments are potentially beneficial for cancer patients. However, the effect of sleep on cancer-related fatigue (CRF) and quality of life (QOL) in cancer patients remains unclear. We conducted a meta-analysis of randomized controlled trials to examine the efficacy of sleep in cancer patients undergoing treatment. METHODS: The PubMed, Ovid, Embase, Cochrane Central Register of Controlled Trials, and China National Knowledge Infrastructure databases were searched to identify suitable studies. Stata 15.0 software was used for statistical analyses. Sensitivity analyses were conducted. Fourteen studies (6 in English and 8 in Chinese) involving 1151 patients were included in the meta-analysis. Ten, five, and six studies that assessed the effects of sleep on CRF, QOL, and quality of sleep, respectively, in cancer patients undergoing treatment were identified. RESULTS: Sleep interventions significantly affected overall CRF (standardized mean difference (SMD) = -1.52, P < 0.01), overall QOL (SMD = 1.20, P < 0.01), physical fatigue (SMD = -0.66, P < 0.01), cognitive fatigue (SMD = -0.38, P = 0.015), and physical function (SMD = 0.64, P < 0.01). Comprehensive intervention measures focusing on sleep, sleep nondrug interventions, and interventions for ≥3 or <3 months affect CRF. However, no significant effects on emotional fatigue, emotional function, perpetual fatigue, depression, or quality of sleep were observed. CONCLUSIONS: Comprehensive interventions focusing on sleep are helpful for CRF. Sleep interventions may only affect physiological function and have no effect on emotional function, perpetual function, or sleep quality. Future research should focus on how to combine sleep interventions with psychological, social, cognitive, and emotional interventions and provide targeted comprehensive nursing measures to better improve CRF, sleep quality, and QOL.

Risk factors for cancer-related fatigue in patients with colorectal cancer: a systematic review and meta-analysis.

PURPOSE: Cancer-related fatigue seriously affects the quality of life of cancer patients, yet few systematic reviews have evaluated the risk factors for cancer-related fatigue in patients with colorectal cancer. We therefore conducted a meta-analysis to assess the risk factors of cancer-related fatigue in patients with colorectal cancer. METHODS: Literature databases, including PubMed, Ovid, Embase, the Cochrane Central Register of Controlled Trials, the Web of Science, the China National Knowledge Infrastructure, Wanfang, and VIP, were searched from their establishment to September 2021 to identify suitable studies. The quality of included studies was assessed using different tools and evaluated independently by two investigators. Review Manager version 5.4 (Cochrane Collaboration, London, UK) was used for statistical analysis, and sensitivity analysis was conducted. RESULTS: In total, 2642 articles were screened, and data from 25 studies involving 8733 subjects were included in this meta-analysis. After controlling for confounding variables, the following risk factors were associated with cancer-related fatigue: younger age, female sex, low physical activity level, a clinical stage of III or IV, surgery, chemotherapy, insomnia, pain, anxiety, and depression. CONCLUSION: Younger age, female sex, low physical activity level, a clinical stage of III or IV, chemotherapy, pain, insomnia, anxiety, and depression were identified as risk factors for cancer-related fatigue. Future research should focus on how multidisciplinary teams adopt targeted measures according to these risk factors to better reduce the incidence of cancer-related fatigue.

Bacillus amyloliquefaciens PMB05 Increases Resistance to Bacterial Wilt by Activating Mitogen-Activated Protein Kinase and Reactive Oxygen Species Pathway Crosstalk in Arabidopsis thaliana.

Bacterial wilt caused by Ralstonia solanacearum can infect many crops, causing significant losses worldwide. The use of beneficial microorganisms is considered a feasible method for controlling this disease. Our previous study showed that Bacillus amyloliquefaciens PMB05 can control bacterial wilt through intensifying immune signals triggered by a pathogen-associated molecular pattern (PAMP) from R. solanacearum. It is still uncertain whether induction of the mitogen-activated protein kinase (MAPK) pathway during PAMP-triggered immunity (PTI) is responsible for enhancing disease resistance. To gain more insights on how the presence of PMB05 regulates PTI signaling, its association with the MAPK pathway was assayed. Our results showed that the activation of MPK3/6 and expression of wrky22 upon treatment with the PAMP, PopW, was increased during co-treatment with PMB05. Moreover, the disease resistance conferred by PMB05 to bacterial wilt was abolished in mekk1, mkk5, and mpk6 mutants. To determine the relationship between the MAPK pathway and plant immune signals, the assay on reactive oxygen species (ROS) generation and callose deposition showed that only the ROS generation was strongly reduced in these mutants. Because ROS generation is highly correlated with RbohD, the results revealed that the effects of PMB05 on both PopW-induced ROS generation and disease resistance to bacterial wilt were eliminated in the rbohD mutant, suggesting that the generation of ROS is also required for PMB05-enhanced disease resistance. Taken together, we concluded that the crosstalk between the initiation of ROS generation and further activation of the MAPK pathway is necessary when PMB05 is used to improve disease resistance to bacterial wilt.

B cell subsets were associated with prognosis in elderly patients with community acquired pneumonia.

BACKGROUND: The role of B cell subsets remained to be elucidated in a variety of immune diseases, though which was used as an effective biomarker for anti-inflammatory or antiviral response. This study aimed to evaluate the early changes of B cell subtypes distribution in elderly patients with community acquired pneumonia (CAP), as well as the association between B cell subtypes and prognosis. METHODS: This prospective study included elderly patients with CAP, severe CAP (sCAP) and healthy elderly subjects between April 2016 and March 2018. Flow cytometry was used to detect CD3, CD20, HLA-DR, CD24, CD27, CD38, IgM, and IgD. CD20+ B cells were further divided into naïve B cells (Bn), IgM/D+ memory B cells (IgM+ Bm), switched B cells (SwB), and transitional B cells (Btr). RESULTS: A total of 22 healthy controls, 87 patients with CAP and 58 patients with sCAP were included in the study. Compared to CAP, sCAP was characterized by significantly lower absolute number of B cells, Bn and Btr, significantly lower Btr and Bn subset percentage, while percentage of IgM+ Bm was significantly higher. Heat map showed Bn and Btr on day 3 and day 7 was negatively correlated with activated partial prothrombin time (APTT), international normalized ratio (INR), sequential organ failure assessment score (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II). After 28-day follow-up, Btr percentage in survival group was significantly higher. Receiver operator characteristic (ROC) curve analysis found that Btr count showed sensitivity of 48.6% and specificity of 87.0% for predicting the 28-day survival, with an area under the ROC curves of 0.689 (p = 0.019). CONCLUSIONS: Severity and prognosis of CAP in elderly people is accompanied by changes in the B cell subsets. Btr subsets could play prognostic role for a short-term mortality of elderly CAP patients.

Traditional Chinese Nursing Using Fennel With Coarse Salt for Ironing and Umbilical Moxibustion for Epigastric Pain With Spleen-stomach Vacuity Cold.

Context: Spleen-stomach vacuity cold is the primary TCM pattern for epigastric pain, accounting for 75% of the patients. According to the TCM theory of treating both the tip and the root, epigastric pain requires the caregiver to dissipate cold and relieve pain, the treatments for the tip, which warm and supplement the spleen and stomach, the treatments for the root. Objective: This study aimed to explore effectiveness of traditional Chinese nursing care using fennel mixed with coarse salt for ironing,with umbilical moxibustion, for epigastric pain, with a pattern of spleen-stomach vacuity cold.

Conclusions: The traditional Chinese nursing care was able to improve epigastric pain, enhance quality of life, and increase satisfaction with the traditional Chinese nursing care.

The support dilemma of stroke inpatients and family caregivers under COVID-19 prevention and control: a qualitative study in China.

China has implemented a strict isolation system in hospitals since the COVID-19 pandemic, that adversely affected the psychology of inpatients and their caregivers. Face-to-face, semi-structured interviews with 22 stroke inpatients from two municipal hospitals were conducted to explore the psychological, emotional and related support needs of stroke inpatients and their family caregivers under this environment. Results which showed that external support for stroke inpatients and their family caregivers was insufficient highlight the necessity for developing specific nursing interventions that meet the psychological and emotional needs of inpatients and the caregivers.

Primary Cilia Restrain PI3K-AKT Signaling to Orchestrate Human Decidualization.

Endometrial decidualization plays a pivotal role during early pregnancy. Compromised decidualization has been tightly associated with recurrent implantation failure (RIF). Primary cilium is an antenna-like sensory organelle and acts as a signaling nexus to mediate Hh, Wnt, TGFß, BMP, FGF, and Notch signaling. However, whether primary cilium is involved in human decidualization is still unknown. In this study, we found that primary cilia are present in human endometrial stromal cells. The ciliogenesis and cilia length are increased by progesterone during in vitro and in vivo decidualization. Primary cilia are abnormal in the endometrium of RIF patients. Based on data from both assembly and disassembly of primary cilia, it has been determined that primary cilium is essential to human decidualization. Trichoplein (TCHP)-Aurora A signaling mediates cilia disassembly during human in vitro decidualization. Mechanistically, primary cilium modulates human decidualization through PTEN-PI3K-AKT-FOXO1 signaling. Our study highlights primary cilium as a novel decidualization-related signaling pathway.
