IL1R2 Blockade Alleviates Immunosuppression and Potentiates Anti-PD-1 Efficacy in Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with limited therapeutic options. IL1 receptor type 2 (IL1R2) promotes breast tumor-initiating cell (BTIC) self-renewal and tumor growth in TNBC, indicating that targeting it could improve patient treatment. In this study, we observed that IL1R2 blockade strongly attenuated macrophage recruitment and the polarization of tumor-associated macrophages (TAM) to inhibit BTIC self-renewal and CD8+ T-cell exhaustion, which resulted in reduced tumor burden and prolonged survival in TNBC mouse models. IL1R2 activation by TAM-derived IL1ß increased PD-L1 expression by interacting with the transcription factor Yin Yang 1 (YY1) and inducing YY1 ubiquitination and proteasomal degradation in both TAMs and TNBC cells. Loss of YY1 alleviated the transcriptional repression of c-Fos, which is a transcriptional activator of PDL-1. Combined treatment with an IL1R2-neutralizing antibodies and anti-PD-1 led to enhanced antitumor efficacy and reduced TAMs, BTICs, and exhausted CD8+ T cells. These results suggest that IL1R2 blockade might be a strategy to potentiate immune checkpoint blockade efficacy in TNBC to improve patient outcomes. Significance: IL1R2 in both macrophages and breast cancer cells orchestrates an immunosuppressive tumor microenvironment by upregulating PD-L1 expression and can be targeted to enhance the efficacy of anti-PD-1 in triple-negative breast cancer.

Ningxin-Tongyu-Zishen formula alleviates the senescence of granulosa cells on D-galactose-induced premature ovarian insufficiency mice.

Ningxin-Tongyu-Zishen formula (NTZF) is a clinical experience formula for the treatment of premature ovarian insufficiency (POI) in traditional Chinese medicine (TCM), and the potential mechanism is unknown. For in vivo experiments, POI mouse models (C57BL/6 mice), were constructed by subcutaneous injection of D-galactose (D-gal, 200 mg/kg). After treatment of NTZF (10.14, 20.27, 40.54 g/kg;) or estradiol valerate (0.15 mg/kg), ovarian function, oxidative stress (OS) and protein expression of Sirt1/p53 were evaluated. For in vitro experiments, H2O2 (200 µM) was used to treat KGN to construct ovarian granulosa cells (OGCs) cell senescence model. Pretreatment with NTZF (1.06 mg/mL) or p53 inhibitor (Pifithrin-α, 1 µM) was performed before induction of senescence, and further evaluated the cell senescence, OS, mRNA and protein expression of Sirt1/p53. In vivo, NTZF improved ovarian function, alleviated OS and Sirt1/p53 signaling abnormalities in POI mice. In vitro experiments showed that NTZF reduced the level of OS and alleviated the senescence of H2O2-induced KGN. In addition, NTZF activated the protein expression of Sirt1, inhibited the mRNA transcription and protein expression of p53 and p21. Alleviating OGCs senescence and protecting ovarian function through Sirt1/p53 is one of the potential mechanisms of NTZF in the treatment of POI.

Macrod1 suppresses diabetic cardiomyopathy via regulating PARP1-NAD+-SIRT3 pathway.

Diabetic cardiomyopathy (DCM), one of the most serious long-term consequences of diabetes, is closely associated with oxidative stress, inflammation and apoptosis in the heart. MACRO domain containing 1 (Macrod1) is an ADP-ribosylhydrolase 1 that is highly enriched in mitochondria, participating in the pathogenesis of cardiovascular diseases. In this study, we investigated the role of Macrod1 in DCM. A mice model was established by feeding a high-fat diet (HFD) and intraperitoneal injection of streptozotocin (STZ). We showed that Macrod1 expression levels were significantly downregulated in cardiac tissue of DCM mice. Reduced expression of Macrod1 was also observed in neonatal rat cardiomyocytes (NRCMs) treated with palmitic acid (PA, 400 µM) in vitro. Knockout of Macrod1 in DCM mice not only worsened glycemic control, but also aggravated cardiac remodeling, mitochondrial dysfunction, NAD+ consumption and oxidative stress, whereas cardiac-specific overexpression of Macrod1 partially reversed these pathological processes. In PA-treated NRCMs, overexpression of Macrod1 significantly inhibited PARP1 expression and restored NAD+ levels, activating SIRT3 to resist oxidative stress. Supplementation with the NAD+ precursor Niacin (50 µM) alleviated oxidative stress in PA-stimulated cardiomyocytes. We revealed that Macrod1 reduced NAD+ consumption by inhibiting PARP1 expression, thereby activating SIRT3 and anti-oxidative stress signaling. This study identifies Macrod1 as a novel target for DCM treatment. Targeting the PARP1-NAD+-SIRT3 axis may open a novel avenue to development of new intervention strategies in DCM. Schematic illustration of macrod1 ameliorating diabetic cardiomyopathy oxidative stress via PARP1-NAD+-SIRT3 axis.

Duhuo Jisheng Decoction regulates intracellular zinc homeostasis by enhancing autophagy via PTEN/Akt/mTOR pathway to improve knee cartilage degeneration.

BACKGROUND: Articular cartilage and cartilage matrix degradation are key pathological changes occurring in the early stage of knee osteoarthritis (KOA). However, currently, there are limited strategies for early prevention and treatment of KOA. Duhuo Jisheng Decoction (DHJSD) is a formula quoted in Bei Ji Qian jin Yao Fang, which was compiled by Sun Simiao in the Tang Dynasty of China. As a complementary therapy, it is widely used to treat early-stage KOA in China; however, its mechanism has not been completely elucidated. OBJECTIVE: This study investigated the potential role of DHJSD in preventing cartilage degradation and the underlying mechanism. METHODS: A rat model of KOA model was established via the Hulth method. Subsequently, 25 rats were randomized into sham (saline), model control (saline), high-DHJSD (1.9g/mL of DHJSD), medium-DHJSD (1.2g/mL of DHJSD), and low-DHJSD groups (0.6g/mL of DHJSD). After 4 weeks of treatment, all rats were sacrificed and the severity of the cartilage degeneration was evaluated by a series of histological methods. The autophagosome was observed using transmission electron microscopy, and the related functional proteins were detected by the western blotting and real-time polymerase chain reaction. Next, the mechanism by which DHJSD improves knee cartilage degeneration was further clarified the in vitro by gene silencing technology combined with a series of functional experiments. The proteins levels of PTEN, Akt, p-Akt, mTOR, and p-mTOR, as well as the marker proteins of autophagy and apoptosis were determined. Zinc levels in chondrocytes were determined using inductively coupled plasma mass spectrometry. RESULTS: Histopathological staining revealed that DHJSD had a protective effect on the cartilage. DHJSD increased autophagosome synthesis and the expression of autophagy proteins LC3 and Beclin-1 in chondrocytes. Moreover, it reduced the phosphorylation levels of Akt and mTOR and the levels of zinc, MMP-13, Bax, and Bcl-2. Following PTEN silencing, this DHJSD-mediated reduction in Akt and mTOR phosphorylation and Bax, Bcl-2, and zinc levels were further decreased; in addition, DHJSD-mediated increase in LC3 and Beclin-1 levels was decreased. CONCLUSION: DHJSD inhibits the Akt/mTOR signaling pathway by targeting PTEN to promote autophagy in chondrocytes, which may help reduce MMP-13 production by regulating zinc levels in chondrocytes.

OBJECTIVE: To evaluate the efficacy and safety of Buzhong Yiqi decoction (, BZYQ) in the treatment of hospital-acquired pneumonia (HAP) with multi-drug-resistant bacteria (MDRB). METHODS: This 28-day study was conducted at 5 clinical centers in Shanghai. The eligible patients were randomly assigned (1:1) into the intervention group (BZYQ plus conventional Western Medicine therapy) and control group (conventional Western Medicine therapy). The primary outcomes were the clinical response, clinical pulmonary infection score (CPIS), and microbiologic response. The secondary outcomes were the 28-day all-cause mortality (ACM), Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, ventilator weaning rate, length of mechanical ventilation (MV), length of hospital stay, and changes of infection indicators. RESULTS: Altogether 83 subjects in the intervention group and 85 subjects in the control group were analyzed. The clinical success rate (48.2%) and the pathogen eradication rate (59.0%) of the intervention group were all better than those of the control group (32.9% and 38.9%, respectively) with statistically significant differences (<0.05). The CPIS score of the intervention group (8.9 ± 1.7) was lower than that of the control group (9.6 ± 2.5) (<0.05). The length of MV in the intervention group [(13.7 ± 6.4) d] was significantly shorter than that of the control group [ (17.2 ± 7.2) d] (<0.05). The 28-day ACM of the intervention group (13.33%) was lower than that of the control group (21.2%) with no statistically significant difference (>0.05). The differences between two groups in ventilator weaning rate, length of hospital stay, and APACHE Ⅱ score were not statistically significant (> 0.05). The intervention group displayed decreases in white blood cell count, C-reactive protein, neutrophil percentage, and procalcitonin at day 28 compared with baseline (<0.05). No serious adverse events occurred in either group during the 28-day follow-up. CONCLUSION: BZYQ may be an effective therapeutic option for the management of HAP with MDRB.

Xiaoyao San, a Chinese herbal formula, ameliorates depression-like behavior in mice through the AdipoR1/AMPK/ACC pathway in hypothalamus / 中西医结合学报

OBJECTIVE@#Depression and metabolic disorders have overlapping psychosocial and pathophysiological causes. Current research is focused on the possible role of adiponectin in regulating common biological mechanisms. Xiaoyao San (XYS), a classic Chinese medicine compound, has been widely used in the treatment of depression and can alleviate metabolic disorders such as lipid or glucose metabolism disorders. However, the ability of XYS to ameliorate depression-like behavior as well as metabolic dysfunction in mice and the underlying mechanisms are unclear.@*METHODS@#An in vivo animal model of depression was established by chronic social defeat stress (CSDS). XYS and fluoxetine were administered by gavage to the drug intervention group. Depression-like behaviors were analyzed by the social interaction test, open field test, forced swim test, and elevated plus maze test. Glucose levels were measured using the oral glucose tolerance test. The involvement of certain molecules was validated by immunofluorescence, histopathology, and Western blotting. In vitro, hypothalamic primary neurons were exposed to high glucose to induce neuronal damage, and the neuroprotective effect of XYS was evaluated by cell counting kit-8 assay. Immunofluorescence and Western blotting were used to evaluate the influences of XYS on adiponectin receptor 1 (AdipoR1), adenosine 5'-monophosphate-activated protein kinase (AMPK), acetyl-coenzyme A carboxylase (ACC) and other related proteins.@*RESULTS@#XYS ameliorated CSDS-induced depression-like behaviors and glucose tolerance impairment in mice and increased the level of serum adiponectin. XYS also restored Nissl bodies in hypothalamic neurons in mice that exhibited depression-like behaviors and decreased the degree of neuronal morphological damage. In vivo and in vitro studies indicated that XYS increased the expression of AdipoR1 in hypothalamic neurons.@*CONCLUSION@#Adiponectin may be a key regulator linking depression and metabolic disorders; regulation of the hypothalamic AdipoR1/AMPK/ACC pathway plays an important role in treatment of depression by XYS.

Wogonin alleviates liver injury in sepsis through Nrf2-mediated NF-κB signalling suppression.

Sepsis is a life-threatening organ dysfunction syndrome, and liver is a susceptible target organ in sepsis, because the activation of inflammatory pathways contributes to septic liver injury. Oxidative stress has been documented to participate in septic liver injury, because it not only directly induces oxidative genotoxicity, but also exacerbates inflammatory pathways to potentiate damage of liver. Therefore, to ameliorate oxidative stress is promising for protecting liver in sepsis. Wogonin is the compound extracted from the medicinal plant Scutellaria baicalensis Geogi and was found to exert therapeutic effects in multiple inflammatory diseases via alleviation of oxidative stress. However, whether wogonin is able to mitigate septic liver injury remains unknown. Herein, we firstly proved that wogonin treatment could improve survival of mice with lipopolysaccharide (LPS)- or caecal ligation and puncture (CLP)-induced sepsis, together with restoration of reduced body temperature and respiratory rate, and suppression of several pro-inflammatory cytokines in circulation. Then, we found that wogonin effectively alleviated liver injury via potentiation of the anti-oxidative capacity. To be specific, wogonin activated Nrf2 thereby promoting expressions of anti-oxidative enzymes including NQO-1, GST, HO-1, SOD1 and SOD2 in hepatocytes. Moreover, wogonin-induced Nrf2 activation could suppress NF-κB-regulated up-regulation of pro-inflammatory cytokines. Ultimately, we provided in vivo evidence that wogonin activated Nrf2 signalling, potentiated anti-oxidative enzymes and inhibited NF-κB-regulated pro-inflammatory signalling. Taken together, this study demonstrates that wogonin can be the potential therapeutic agent for alleviating liver injury in sepsis by simultaneously ameliorating oxidative stress and inflammatory response through the activation of Nrf2.

Melatonin induces the rejuvenation of long-term ex vivo expanded periodontal ligament stem cells by modulating the autophagic process.

BACKGROUND: Stem cells that have undergone long-term ex vivo expansion are most likely functionally compromised (namely cellular senescence) in terms of their stem cell properties and therapeutic potential. Due to its ability to attenuate cellular senescence, melatonin (MLT) has been proposed as an adjuvant in long-term cell expansion protocols, but the mechanism underlying MLT-induced cell rejuvenation remains largely unknown. METHODS: Human periodontal ligament stem cells (PDLSCs) were isolated and cultured ex vivo for up to 15 passages, and cells from passages 2, 7, and 15 (P2, P7, and P15) were used to investigate cellular senescence and autophagy change in response to long-term expansion and indeed the following MLT treatment. Next, we examined whether MLT could induce cell rejuvenation by restoring the autophagic processes of damaged cells and explored the underlying signaling pathways. In this context, cellular senescence was indicated by senescence-associated ß-galactosidase (SA-ß-gal) activity and by the expression of senescence-related proteins, including p53, p21, p16, and γ-H2AX. In parallel, cell autophagic processes were evaluated by examining autophagic vesicles (by transmission electronic microscopy), autophagic flux (by assessing mRFP-GFP-LC3-transfected cells), and autophagy-associated proteins (by Western blot assay of Atg7, Beclin-1, LC3-II, and p62). RESULTS: We found that long-term in vitro passaging led to cell senescence along with impaired autophagy. As expected, MLT supplementation not only restored cells to a younger state but also restored autophagy in senescent cells. Additionally, we demonstrated that autophagy inhibitors could block MLT-induced cell rejuvenation. When the underlying signaling pathways involved were investigated, we found that the MLT receptor (MT) mediated MLT-related autophagy restoration by regulating the PI3K/AKT/mTOR signaling pathway. CONCLUSIONS: The present study suggests that MLT may attenuate long-term expansion-caused cellular senescence by restoring autophagy, most likely via the PI3K/AKT/mTOR signaling pathway in an MT-dependent manner. This is the first report identifying the involvement of MT-dependent PI3K/AKT/mTOR signaling in MLT-induced autophagy alteration, indicating a potential of autophagy-restoring agents such as MLT to be used in the development of optimized clinical-scale cell production protocols.

But the regimen of acupuncture- moxibustion needs to be further optimized and promoted.

Mechanism of Traditional Chinese Medicine in Treatment of Autism Spectrum Disorder Based on Heart and Spleen / 中国实验方剂学杂志

Autism spectrum disorder （ASD） is a common neurodevelopmental disorder in childhood， whereas there is no specific medicine at present. There are more and more researches on the treatment of ASD with traditional Chinese medicine（TCM） which the curative effect is reliable. The heart and spleen are the main viscera for the treatment of ASD， but there is still a lack of in-depth analysis of the mechanism of TCM. In order to explore the relationship between the core symptoms of ASD and the heart and spleen， this article specifically explores the theoretical origins of the heart and the spleen in the formation of the core symptoms of ASD， and to clarify the role of the heart and spleen in the occurrence and development of the two core symptoms of ASD from the perspective of TCM. In view of social communication and communication obstacles， the author puts forward and explains the language problems of children with ASD based on the functions of the heart and spleen， the theory of the viscera， the ascription of the meridians， and the classics. The mechanism of the heart and spleen in TCM about the failure of the spleen， the loss of the heart， and the endogenous phlegm. Aiming at the mechanism of the stereotyped symptoms of abnormal behaviors in children with ASD， this paper proposes and explains the TCM mechanism of constant deficiency of the spleen and dereliction of duty， leading to loss of mind， heart and spleen injury， and finally a series of stereotypes and strange syndromes due to lack of spirit. Through the analysis and excavation of TCM theory， it explores theoretical basis for ASD from the theory of heart and spleen， with a view to preliminarily constructing the theoretical framework of TCM syndrome differentiation and treatment of the deficiency of both the heart and spleen， and provide theoretical reference for TCM syndrome differentiation and treatment of ASD. The treatment of ASD from the differentiation of symptoms and signs of the heart and spleen is supported by a strong theoretical basis of TCM， and the rationale， law and prescriptions are complete， which may be the direction of screening effective TCM prescriptions for the treatment of ASD in the future.

Multidisciplinary and Comprehensive Chinese Medicine for Advanced Non-Small Cell Lung Cancer Patients: A Retrospective Study of 855 Cases / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of multidisciplinary and comprehensive Chinese medicine (CM) treatments on progression-free survival (PFS) and median survival time (MST) in patients with advanced non-small cell lung cancer (NSCLC) and identify factors that influence progression and prognosis.@*METHODS@#Clinical data of 855 patients with advanced NSCLC who received multidisciplinary and comprehensive CM treatments at Longhua Hospital from January 2009 to December 2018 were retrospectively analyzed. Univariate analysis was performed by the Kaplan-Meier method and log-rank sequential inspection. Multivariate analysis of significant variables from the univariate analysis was performed with Cox regression modeling. Key factors correlated to progression and prognosis were screened out, and a Cox proportional hazard model was established to calculate the prognostic index.@*RESULTS@#The PFS and MST of 855 advanced NSCLC patients were 9.0 and 26.0 months, respectively. The 1-, 2-, 3-, and 5-year survival rates were 79.2%, 54%, 36.2%, and 17.1%, respectively. Gender, pathologic type, and clinical stage were independent prognostic risk factors; surgical history, radiotherapy, treatment course of Chinese patent medicine, intravenous drip of Chinese herbal preparation, duration of oral administration of Chinese herbal decoction (CHD), and intervention measures were independent prognostic protective factors. Gender was an independent risk factor for progression, while operation history and oral CHD administration duration were independent protective factors (all P<0.05). Women with stage IIIb-IIIc lung adenocarcinoma had the best outcomes.@*CONCLUSIONS@#Female patients have lower progression risk and better prognoses than male patients, younger patients have higher progression risk but better long-term prognoses than the elderlys, and patients with lower performance status scores are at lower risk for progression and have better prognoses. Comprehensive CM treatments could significantly reduce progression risk, improve prognosis, and prolong survival time for patients with advanced NSCLC. This treatment mode offers additional advantages over supportive care alone.

Objective::To study the effect of warming and heat-clearing method (Wenyang Jiedu Huayu decoction) on the expressions of Forkhead box P3 (FoxP3), Retinoic acid-related orphan receptor gamma t (ROR-γt) in colon tissue of mice with acute-on-chronic liver failure (ACLF), in order to explore the possible regulatory mechanism on intestinal endotoxemia (IETM) in liver failure mice. Method::The 130 SD rats were randomly divided into normal group (10 rats) and model group (120 rats). The ACLF mice model was established through the subcutaneous injection with bovine serum albumin and the intraperitoneal injection with D-galactosamine(D-Gal) and lipopolysaccharide (LPS). The model mice were randomly divided into model group, heat-clearing group (Yinchenhao decoction, 6.68 g·kg-1), warming group (Yinchen Zhufu decoction, 7.09 g·kg-1) and warming and heat-clearing group (Wenyang Jiedu Huayu decoction, 19.53 g·kg-1). The normal group and the model group were given distilled water by gastric lavage, while the other groups were given equal volume of corresponding Chinese herbal medicines for a week. The value of each index at 1, 12 and 24 h was measured. The ratio of Treg/Th17 cell in peripheral blood were detected and calculated by flow cytometry. Real-time fluorescence quantitative PCR (Real-time PCR) was used to detect the expressions of FoxP3 and ROR-γt in colon tissues of mice at different time points. In situ hybridization and immunohistochemistry were used to observe the expressions of FoxP3 and ROR-γt genes and proteins. Result::Compared with normal group, the ratio of Treg/Th17 in the model group decreased significantly at each time point (P<0.01). Compared with the model group, the Treg/Th17 ratio increased only in the warming and heat-clearing method group (P<0.05). Compared with normal group, the expression of ROR-γt in the model group was significantly higher (P<0.01), and the expression of ROR-γt in the model group was higher than FoxP3.Compared with the model group, the expressions of FoxP3 and ROR-γt mRNA in the heat-clearing group and the warming group decreased at each time point (P<0.05), and the expressions of FoxP3 and ROR-γt in the warming and heat-clearing method group decreased significantly (P<0.01). The expressions of FoxP3 and ROR-γt mRNA in warming and heat-clearing group decreased compared with those in the warming group and heat-clearing group (P<0.05). Conclusion::The mechanism of the warming and heat-clearing method on IETM in liver failure may be related to the regulation of FoxP3 and ROR-γt expressions.

Objective::To detect the expression levels of peripheral blood Treg/Th17 cells and related cytokines in patients with Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) with different traditional Chinese medicine (TCM) syndrome " Yanghuang-Yinyanghuang-Yinhuang" , in order to explore the cellular immunological characteristics of different TCM syndromes of liver failure. Method::The 32 cases of patients with HBV-ACLF in early, middle and late stages in line with the " Yanghuang-Yinyanghuang-Yinhuang" TCM syndrome grouping were selected. Flow cytometry was used to detect the frequency expression of Treg/Th17 cells in peripheral blood. The expression levels of interleukin-10(IL-10), transforming growth factor-β(TGF-β), interleukin-17A(IL-17A), tumor necrosis factor-α(TNF-α) and interleukin-23(IL-23) were detected by cytometric bead array (CBA). The expressions of transcription factor forkhead box P3(FoxP3) and retinoid-related orphan nuclear receptor-γt(ROR-γt) mRNA were detected by Real-time PCR. The SPSS 20.0 software was applied in data statistics and processing to analyze the expression characteristics of Treg/Th17 cells and related cytokines in patients with different TCM syndrome types of HBV-ACLF. Result::The patients with HBV-ACLF Yanghuang syndrome were mainly distributed in the early stage of liver failure, those with Yinyanghuang syndrome were mainly distributed in the middle stage, and those with Yinhuang syndrome were distributed in the late stage. From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, the frequency of Treg and Th17 cells gradually increased, and the differences among the groups were statistically significant (P<0.05). From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, Treg cytokines IL-10, TGF-β gradually increased, and the differences among the groups were statistically significant (P<0.05). Th17 cytokines IL-17A, TNF-α, IL-23 gradually increased, of which IL-17A were differences between Yanghuang syndrome and the Yinyanghuang syndrome, as well as Yanghuang syndrome and Yinhuang syndrome (P<0.05). From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, the expression of FoxP3 was gradually decreased, while that of ROR-γt was gradually increased, and the differences among the groups were statistically significant (P<0.01). Conclusion::There is a certain correlation between the different course of early, middle and late stages of HBV-ACLF and the distribution of TCM syndromes. The frequency of Treg and Th17 cells and the correlation of IL-17A, TGF-β and IL-10 with TCM syndrome differentiation are related, suggesting that Treg and Th17 cells have a certain reference value for the diagnosis of patients with HBV-ACLF and the syndrome differentiation of TCM syndromes.

Retrospective Study of Clinical Features and Traditional Chinese Medicine Syndrome Characteristics on HBV-ACLF Patients with Bacterial Infection / 中国实验方剂学杂志

Objective::Through the retrospective study of Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) patients, the clinical features and the characteristics of traditional Chinese medicine (TCM) syndrome distribution of HBV-ACLF complicated with bacterial infection were preliminarily expounded, so as to provide the corresponding theoretical basis for the diagnosis and treatment of HBV-ACLF secondary bacterial infection. Method::A unified data collection form for patients with slow plus acute liver failure was designed by the retrospective epidemiological investigation method. The clinical data of 307 patients with HBV-ACLF who were hospitalized at the Hepatology Institute of the First Affiliated Hospital of Hunan University of Chinese Medicine were collected in strict accordance with the inclusion and exclusion standards, and the main symptoms and the TCM symptoms were screened. Then, according to whether or not there was a bacterial infection, the patients were divided into a combined bacterial infection group and a non-combined bacterial infection group. The distribution characteristics of the main symptoms and the TCM symptoms in two groups were compared, and the distribution characteristics of TCM symptoms of HBV-ACLF with bacterial infection were obtained. Result::Compared with patients with uncombined bacterial infection, patients with combined bacterial infection had significantly increased abdominal distension, puffiness, purple and dark tongue color, abdominal varicose tendons, subcutaneous stasis spots, and tooth marks on the side of the tongue. Compared with patients with combined bacterial infections, patients with uncombined bacterial infections mainly showed bright yellow head, yellow tongue coating, and significantly increased dry mouth (P<0.05, P<0.01). The main symptoms of patients with combined bacterial infections was the combination of syndrome (93.6%), and more spleen deficiency syndrome (81.6%), patients with uncombined bacterial infections mainly suffered from a single syndrome (53.5%), which was mostly damp-heat syndrome (51.9%), patients of concurrent syndrome with combined bacterial infections mostly suffered from false and real syndrome (94.4%), which was significantly higher than those with uncombined bacterial infections (58.9%). Conclusion::The patients with HBV-ACLF without bacterial infection mainly suffered from damp-heat symptoms and signs. With the combination of bacterial infection, the symptoms and signs of spleen deficiency and blood stasis gradually worsened. HBV-ACLF patients with bacterial infection mainly suffered from spleen deficiency and blood stasis, while patients with unincorporated bacterial infection mainly suffered from the single damp-heat symptoms and signs.

Efficacy of internet-based integrated intervention on depression and anxiety symptoms in patients with COVID-19 / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Public health crises, such as the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) since Dec. 2019, are widely acknowledged as severe traumatic events that impose threats not only because of physical concerns but also because of the psychological distress of infected patients. We designed an internet-based integrated intervention and evaluated its efficacy on depression and anxiety symptoms in patients infected by SARS-CoV-2.

Copper promotes the migration of bone marrow mesenchymal stem cells via Rnd3-dependent cytoskeleton remodeling.

The motility of mesenchymal stem cells (MSCs) is highly related to their homing in vivo, a critical issue in regenerative medicine. Our previous study indicated copper (Cu) might promote the recruitment of endogenous MSCs in canine esophagus defect model. In this study, we investigated the effect of Cu on the motility of bone marrow mesenchymal stem cells (BMSCs) and the underlying mechanism in vitro. Cu supplementation could enhance the motility of BMSCs, and upregulate the expression of hypoxia-inducible factor 1α (Hif1α) at the protein level, and upregulate the expression of rho family GTPase 3 (Rnd3) at messenger RNA and protein level. When Hif1α was silenced by small interfering RNA (siRNA), Cu-induced Rnd3 upregulation was blocked. When Rnd3 was silenced by siRNA, the motility of BMSCs was decreased with or without Cu supplementation, and Cu-induced cytoskeleton remodeling was neutralized. Furthermore, overexpression of Rnd3 also increased the motility of BMSCs and induced cytoskeleton remodeling. Overall, our results demonstrated that Cu enhanced BMSCs migration through, at least in part, cytoskeleton remodeling via Hif1α-dependent upregulation of Rnd3. This study provided an insight into the mechanism of the effect of Cu on the motility of BMSCs, and a theoretical foundation of applying Cu to improve the recruitment of BMSCs in tissue engineering and cytotherapy.
