The Extracts Derived from Artemisia japonica Thunb. Leaves Mitigate Oxidative Stress and Inflammatory Response Induced by LPS in RAW264.7 Cells through Modulation of the Nrf2/HO-1 Signaling Pathway.

Artemisia japonica Thunb. has been used as a traditional Chinese medicine and a vegetable for thousands of years in China. However, there are few reports on the chemical composition and biological activity of its leaves. Thus, this study aimed to evaluate the chemical composition, antioxidant and anti-inflammatory effects of water extracts of A. japonica leaves and their underlying mechanisms. A total of 48 compounds were identified in the water extract using UPLC-QTOF-MS2 analysis, with phenolic acids, particularly chlorogenic acid compounds, being the predominant components. The ethyl acetate fraction (EAF) contained most of the total phenolic content (385.4217 mg GAE/g) and displayed superior antioxidant capacity with the IC50DPPH•, IC50ABTS•+, and OD0.5reducing power at 10.987 µg/mL, 43.630 µg/mL and 26.883 µg/mL, respectively. Furthermore, EAF demonstrated potent antioxidant and anti-inflammatory effects in LPS-induced RAW264.7 cells by upregulating the Nrf2/HO-1 signal pathway. These findings highlight that A. japonica leaves possess remarkable abilities to mitigate inflammation and oxidative stress, suggesting their potential utilization as medicinal agents and food additives for promoting human health.

Formononetin attenuates cigarette smoke-induced COPD in mice by suppressing inflammation, endoplasmic reticulum stress, and apoptosis in bronchial epithelial cells via AhR/CYP1A1 and AKT/mTOR signaling pathways.

Chronic obstructive pulmonary disease (COPD) is a chronic, progressive, and lethal lung disease with few treatments. Formononetin (FMN) is a clinical preparation extract with extensive pharmacological actions. However, its effect on COPD remains unknown. This study aimed to explore the effect and underlying mechanisms of FMN on COPD. A mouse model of COPD was established by exposure to cigarette smoke (CS) for 24 weeks. In addition, bronchial epithelial BEAS-2B cells were treated with CS extract (CSE) for 24 h to explore the in vitro effect of FMN. FMN significantly improved lung function and attenuated pathological lung damage. FMN treatment reduced inflammatory cell infiltration and pro-inflammatory cytokines secretion. FMN also suppressed apoptosis by regulating apoptosis-associated proteins. Moreover, FMN relieved CS-induced endoplasmic reticulum (ER) stress in the mouse lungs. In BEAS-2B cells, FMN treatment reduced CSE-induced inflammation, ER stress, and apoptosis. Mechanistically, FMN downregulated the CS-activated AhR/CYP1A1 and AKT/mTOR signaling pathways in vivo and in vitro. FMN can attenuate CS-induced COPD in mice by suppressing inflammation, ER stress, and apoptosis in bronchial epithelial cells via the inhibition of AhR/CYP1A1 and AKT/mTOR signaling pathways, suggesting a new therapeutic potential for COPD treatment.

National survey on the availability of oncology palliative care services at tertiary general and cancer hospitals in China.

BACKGROUND: This nationwide survey studied the level of palliative care (PC) access for Chinese patients with cancer among cancer care providers either in tertiary general hospitals or cancer hospitals in China. METHODS: Using a probability-proportionate-to-size method, we identified local tertiary general hospitals with oncology departments to match cancer hospitals at the same geographic area. A PC program leader or a designee at each hospital reported available PC services, including staffing, inpatient and outpatient services, education, and research, with most questions adapted from a previous national survey on PC. The primary outcome was availability of a PC service. RESULTS: Most responders reported that some type of PC service (possibly called "comprehensive cancer care," "pain and symptom management," or "supportive care") was available at their institution (84.3% of tertiary general hospitals, 82.8% of cancer hospitals). However, cancer hospitals were significantly more likely than tertiary general hospitals to have a PC department or specialist (34.1% vs. 15.5%, p < 0.001). The most popular services were pain consultation (> 92%), symptom management (> 77%), comprehensive care plans (~ 60%), obtaining advanced directives and do-not-resuscitate orders (~ 45%), referrals to hospice (> 32%), and psychiatric assessment (> 25%). Cancer hospitals were also more likely than tertiary general hospitals to report having inpatient beds for PC (46.3% vs. 30.5%; p = 0.010), outpatient PC clinics (28.0% vs. 16.8%; p = 0.029), educational programs (18.2% vs. 9.0%, p = 0.014), and research programs (17.2% vs. 9.3%, p < 0.001). CONCLUSIONS: Cancer hospitals are more likely to offer PC than are tertiary general hospitals in China. Our findings highlight opportunities to further increase the PC capacity in Chinese hospitals.

Amelioration of chronic prostatitis by fractions of Mongolian medicine Hosta plantaginea flowers via inhibition of NF-κB, MAPKs, JAK-STAT, and PI3K-Akt signaling pathways in rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Hosta plantaginea (Lam.) Aschers flower is an important Mongolian medicine beneficial in the treatment of chronic prostatitis (CP) in the absence of scientific evidence. AIM OF THE STUDY: The aim of this study was to reveal the therapeutical effects and potential mechanisms of H. plantaginea flowers extract (HP) and its different polarity fractions (HPA∼D) on autoimmune CP (ACP) model rats. MATERIALS AND METHODS: Sprague-Dawley male rats were randomly assigned to 13 groups (n = 6/group). Except the sham group, all rats were injected with a mixture of prostate antigen and complete Freund's adjuvant on days 0, 7, and 21 to establish ACP model rats. Afterwards, ACP model rats were orally gavaged with HP or HPA∼D (1 and 4 g/kg of raw herbal material) or positive drug (Prostat, 200 mg/kg) daily from day 21 to day 50 for 30 days, while the sham and model groups were treated simultaneously with isopyknic of 0.3% sodium carboxymethyl cellulose. Histopathological analysis, biochemical parameters, and protein expression of prostate tissues were investigated. RESULTS: In comparison with the model group, all fraction groups experienced improved CP effects, including restored body weight, reduced prostate gland edema and prostate index, decreased prostatic leukocytes, increased prostatic lecithin bodies, and alleviated histopathological damage to prostate tissue. Furthermore, all fraction groups markedly inhibited the phosphorylated protein of nuclear factor kappa-B p65 (NF-κB p65), NF-κB inhibitor alpha (IκBα), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase (Erk), just another kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), phosphoinositide 3-kinase (PI3K), and protein kinase B (Akt) than the model group. CONCLUSION: All fractions of HP exerted significant anti-CP effects by inhibiting NF-κB, MAPKs, JAK-STAT and PI3K-Akt pathways in ACP model rats. These findings provide scientific evidence that H. plantaginea flowers can be used as a pivotal Mongolian medicine in clinical applications for the treatment of CP.

Two new isoflavones from the barks of Dalbergia hancei Benth.

Two new isoflavone compounds, Dalhancei A (1) and Dalhancei B (2), along with a known compound epicatechin (3) were isolated from 80% methanol extract of the barks of Dalbergia hancei Benth. The structures of compounds 1-3 were elucidated by comparison with the literature and physical data analysis, including optical rotation, MS, 1D and 2D NMR spectra. Compounds 1 and 2 showed weak inhibitory activity against tyrosinase at 16.22 mmol/L, with inhibition rates of 42.23 ± 0.18% and 45.68 ± 0.17%, respectively; compound 1 exhibited weak inhibitory activity against α-glucosidase with the inhibition rate of 43.72 ± 0.22% at 5.41 mmol/L, compounds 2 and 3 had better α-glucosidase inhibitory activity than compound 1 with IC50 values of 0.90 ± 0.18 and 0.41 ± 0.17 mmol/L, respectively.

Coronary artery calcium and cystatin C for risk stratification of MACCEs and all-cause death in symptomatic patients.

OBJECTIVES: The aim of this study was to examine the independent and joint associations of baseline coronary artery calcium score (CACS) and cystatin C (Cys-C) with the risk of major adverse cardiac and cerebrovascular events (MACCEs) and all-cause death in symptomatic populations. METHODS: The study included 7140 patients with symptom of chest pain who underwent cardiac computerized tomography examinations to measure CACS. All of them had serum Cys-C results. Endpoints were set for MACCEs and all-cause death events. RESULTS: A total of 7140 participants were followed for a median of 1106 days. A total of 305 patients had experienced MACCEs and 191 patients had experienced all-cause death. CACS ≥ 100 and Cys-C ≥ 0.995 mg/L were independently associated with an increased risk of MACCEs (adjusted hazard ratio [HR]: 1.46; 95% confidence interval [CI]: 1.15-1.85; p = .002 and adjusted HR: 1.57; 95% CI: 1.24-2.00; p < .001, respectively). Compared with CACS < 100 and Cys-C < 0.995 mg/L patients, CACS ≥ 100 and Cys-C ≥ 0.995 mg/L patients had the highest risk of MACCEs and all-cause death (adjusted HR: 2.33; 95% CI: 1.64-3.29; p < .001 and adjusted HR: 2.85; 95% CI: 1.79-4.55; p < .001, respectively). Even in patients with CACS < 100, Cys-C ≥ 0.995 mg/L was also associated with a higher risk of MACCEs and all-cause death than Cys-C < 0.995 mg/L (adjusted HR: 1.76; p = .003 and adjusted HR: 2.02; p = .007, respectively). CONCLUSIONS: The combined stratification of CACS and Cys-C showed an incremental risk of MACCEs and all-cause death, reflecting complementary prognostic value. Our results support the combination of the two indicators for risk stratification and event prediction.

Effects of intercropping on Se accumulation and growth of pakchoi, lettuce and radish.

Selenium is one of the most basic trace elements in the human body. It is necessary to improve the selenium content in agricultural products through agricultural planting technology to ensure that human nutrition and health need selenium. Therefore, our research passed the effect of intercropping on the growth and selenium accumulation of pakchoi, lettuce and radish were studied through pot experiments to determine whether intercropping of the three crop species can improve their selenium accumulation ability. The results showed that intercropping increased the root and shoot biomass of pakchoi and radish compared with the monocultures, while the biomass of roots and shoots decreased in other intercropping combinations. Intercropping also affected the photosynthetic pigment content of the three crop species. Specifically, the photosynthetic pigments increased in pakchoi and decreased in radish after intercropping. Notably, intercropping the three crop species together increased the SOD (superoxide dismutase) activities of the three crops compared with the monocultures. Meanwhile, intercropping radish with lettuce significantly increased the activities of SOD and CAT (catalase) in radish. Intercropping also increased the soluble sugar content in pakchoi and soluble protein content of radish relative to the monocultures. Furthermore, intercropping decreased the selenium content and the bioconcentration factor of the roots of the three vegetable crops, but improved the shoot selenium content, the bioconcentration factor and the transport factor of Se in pakchoi and radish. In conclusion, intercropping combination of pakchoi and radish can improve selenium accumulation in the edible parts of the crops, which is significant for efficient production of selenium-enriched vegetables.

This research is significant because this study provides some basis for improving the selenium content of plants and efficient production of pakchoi and radish. Under the condition of selenium application in soil, the intercropping of pakchoi and lettuce can promote the growth of both and improve their selenium enrichment ability.

Sex and Circadian Timing Modulate Oxaliplatin Hematological and Hematopoietic Toxicities.

Oxaliplatin was nearly twice as hematotoxic, with optimal circadian timing differing by 6 h, in women as compared to men with colorectal cancers. Hence, we investigated sex- and timing-related determinants of oxaliplatin hematopoietic toxicities in mice. Body-weight loss (BWL), blood cell counts, bone marrow cellularity (BMC) and seven flow-cytometry-monitored hematopoietic progenitor populations were evaluated 72 h after oxaliplatin chronotherapy administration (5 mg/kg). In control animals, circadian rhythms of circulating white blood cells showed a peak at ZT5 in both sexes, whereas BMC was maximum at ZT20 in males and ZT13h40 in females. All BM progenitor counts presented robust rhythms with phases around ZT3h30 in females, whereas only three of them rhythmically cycled in males with a ≈ -6 h phase shift. In treated females, chronotoxicity rhythms occurred in BWL, WBC, BMC and all BM progenitors with the best timing at ZT15, ZT21, ZT15h15 and ZT14h45, respectively. In males, almost no endpoints showed circadian rhythms, BWL and WBC toxicity being minimal, albeit with a substantial drop in BM progenitors. Increasing dose (10 mg/kg) in males induced circadian rhythms in BWL and WBC but not in BM endpoints. Our results suggest complex and sex-specific clock-controlled regulation of the hematopoietic system and its response to oxaliplatin.

Effects of 12 weeks of Tai Chi Chuan intervention on the postural stability and self-reported instability in subjects with functional ankle instability: Study protocol for a randomized controlled trial.

Background: Tai Chi Chuan (TCC) is a physical activity modality that originated in China and is now widely popular around the world. Although there are a series of articles reporting that TCC can improve balance and other functional symptoms in a variety of populations, including the elderly, patients with stroke, and patients with Parkinson's disease, its efficiency has not been scientifically and methodically evaluated in subjects with functional ankle instability (FAI). Moreover, there is no literature directly comparing TCC and conventional balance training (CBT) interventions for FAI. The objective of this study is to investigate the comparative effects of TCC intervention and CBT protocols in improving postural balance and subjective instability feelings in patients with FAI. Methods: This study will be a single-center, parallel group, randomized controlled trial. Sixty-eight patients with FAI will be included and randomly assigned in a 1:1 ratio to either an intervention group (n =34) or a control group (n = 34). The participants in the intervention group will complete 12 weeks of TCC intervention (40 min/time, 3 times/week for 12 weeks) on the basis of health education treatment. The control group will receive health education and 36 CBT sessions during a 12-week period. Outcome measures include postural stability and self-reported feelings of instability at baseline, after the end of the intervention, and 3-month follow-up. The postural stability assessment of patients with FAI will be detected by performing static and dynamic postural tests, which will be carried out through a specific balance platform (TecnoBody ProKin). Self-reported feelings of instability will be assessed by Cumberland Ankle Instability Tool (CAIT), American Orthopedics Foot and Ankle Society's Ankle-Hindfoot Evaluation Scale (AOFAS-AHES), and the MOS item Short Form Health Survey (SF-36). Discussion: This trial will demonstrate whether a 12-week TCC intervention positively affects postural stability and self-reported outcomes in patients with FAI. At the same time, the superiority of its clinical efficacy will also be compared with that of CBT. This study may also help to redefine the value of traditional Chinese exercises in the treatment of chronic ankle instability.

The effects of a nurse-led integrative medicine-based structured education program on self-management behaviors among individuals with newly diagnosed type 2 diabetes: a randomized controlled trial.

BACKGROUND: International guidelines advocate providing prompt structured education to individuals with diabetes at diagnosis. However, among the few eligible structured education programs, heterogeneous intervention regimens and inconsistent findings were reported. Eligible programs for Chinese individuals with diabetes are lacking. This study aimed to investigate the effects of a nurse-led integrative medicine-based structured education program on self-management behaviors, glycemic control and self-efficacy among individuals with newly diagnosed type 2 diabetes. METHODS: Employing a randomized controlled trial, 128 individuals with type 2 diabetes diagnosed in the preceding three to nine months were recruited from four university-affiliated tertiary hospitals in Xi'an City, Northwest China, and randomly allocated to the intervention or control groups after baseline assessments. Participants in the intervention group received a 4-week nurse-led integrative medicine-based structured education program, which is theoretically based on the Health Belief Model and Self-Efficacy Theory, in line with updated diabetes management guidelines, and informed by relevant systematic reviews. Participants in the control group received routine care. Self-management behaviors and self-efficacy were measured with the Summary of Diabetes Self-Care Activities and the Diabetes Management Self-Efficacy Scale at baseline, immediate post-intervention and 12 weeks following the intervention while Glycated Hemoglobin A was measured at baseline and the 12th-week follow-up. The intervention effects were estimated using the generalized estimating equation models. RESULTS: Participants in the intervention group exhibited significantly better self-management performance in specific diet regarding intake of fruits and vegetables at both follow-ups (ß = 1.02, p = 0.011 and ß = 0.98, p = 0.016, respectively), specific diet regarding intake of high-fat foods at the immediate post-intervention follow-up (ß = 0.83, p = 0.023), blood glucose monitoring at the 12th-week follow-up (ß = 0.64, p = 0.004), foot care at both follow-ups (ß = 1.80, p <  0.001 and ß = 2.02, p <  0.001, respectively), and medication management at both follow-ups (ß = 0.83, p = 0.005 and ß = 0.95, p = 0.003, respectively). The intervention also introduced significant improvements in Glycated Hemoglobin A (ß = - 0.32%, p <  0.001), and self-efficacy at both follow-ups (ß = 8.73, p <  0.001 and ß = 9.71, p <  0.001, respectively). CONCLUSIONS: The nurse-led integrative medicine-based structured education program could produce beneficial effects on multiple diabetes self-management behaviors, glycemic control and self-efficacy. TRIAL REGISTRATION: This study was retrospectively registered in the ClinicalTrials.gov . on 25/08/2017; registration number: NCT03261895 .

Innovative utilization of herbal residues: Exploring the diversity of mechanisms beneficial to regulate anaerobic fermentation of alfalfa.

In order to increase the utilization of herbal residues, realize efficient utilization of resources, the bacterial community and anaerobic fermentation characteristics of alfalfa ensiling treated with 36 kinds of herbal residues were studied. All the herbal residues improved the anaerobic fermentation quality in different degrees, indicated by lower pH, NH3-N and butyric acid concentrations. However, the contents of lactic and acetic acids varied widely in silage with different herbal residues. Pearson's correlation analysis showed that the improved fermentation quality was closely associated with the variation of lactic acid bacteria community. Consequently, the herbal residues could improve anaerobic fermentation quality by stimulating desirable Lactobacillus species and inhibiting undesirable microbes. This study provides new insights for efficient utilization of herbal residues.

Nonylphenol exposure-induced oocyte quality deterioration could be reversed by melatonin supplementation in mice.

Nonylphenol (NP) belongs to the metabolites of commercial detergents, which acts as an environmental endocrine disruptor. NP is reported to have multiple toxicity including reproductive toxicity. In present study, we reported the protective effects of melatonin on the NP-exposed oocyte quality. We set up a mouse in vivo model of NP exposure (500 µg/L), by daily drinking and continued feeding for 4 weeks; and we gave a daily dose of melatonin (30 mg/kg) to the NP-exposed mice. Melatonin supplementation restores the development ability of oocytes exposed to NP, and this was due to the reduction of ROS level and DNA damage by melatonin. Melatonin could rescue aberrant mitochondria distribution, mitochondria membrane potential, which also was reflected by ATP content and mtDNA copy number. Moreover, melatonin could restore the RPS3 expression to ensure the ribosome function for protein synthesis, and reduced GRP78 protein level to protect against ER stress and ER distribution defects. We also found that vesicle protein Rab11 from Golgi apparatus was protected by melatonin at the spindle periphery of oocytes of NP-exposed mice, which further moderated LAMP2 for lysosome function. Our results indicate that melatonin protects oocytes from NP exposure through its effects on the reduction of oxidative stress and DNA damage, which might be through its amelioration on the organelles in mice.

Exploring miRNA-related Molecular Targets of Erchen Decoction against Lipid Metabolism Disorder using a Network Pharmacologic Approach.

BACKGROUND: Erchen Decoction (ECD) is a complex herbal formulation widely used for treating lipid metabolism disorder (LMD) in China. This study aims to explore the microRNA (miRNA)-related molecular targets of ECD against LMD using a network pharmacology approach (NPA) Methods: We randomly divided 20 male Sprague Dawley rats into two groups; 10 rats were normal controls, and the other 10 rats were fed a high-fat diet (HFD) for 12 weeks to establish an LMD model. Differentially expressed miRNAs (DE-miRs, HFD vs. Control) in the rats' liver tissues were identified by miRNA sequencing and validated with qRT-PCR. Finally, the miRNArelated molecular targets for ECD activity against LMD were identified using a standard NPA by finding the intersection between identified DE-miRs-related targets and ECD-related targets. RESULT: We identified 8 DE-miRs and 968 targets and compared them to 262 ECD-related targets. A final list of 22 candidate targets was identified. Using a confidence score of >0.4, the network of (protein-protein interaction) PPI relationships exhibited 22 nodes and 67 edges. The GO and KEGG enrichment analyses revealed 171 molecular targets and 59 pathways, which were associated with ECD against LMD. CONCLUSION: The identified molecular targets and pathways suggest that complex mechanisms are involved in ECD's mechanism of action, and immune-inflammation-related mechanisms are closely associated with the effects of ECD. The targets obtained in this study will guide future studies on the pharmacologic effects of ECD.

Identification of Key Candidate Genes and Chemical Perturbagens in Diabetic Kidney Disease Using Integrated Bioinformatics Analysis.

Globally, nearly 40 percent of all diabetic patients develop serious diabetic kidney disease (DKD). The identification of the potential early-stage biomarkers and elucidation of their underlying molecular mechanisms in DKD are required. In this study, we performed integrated bioinformatics analysis on the expression profiles GSE111154, GSE30528 and GSE30529 associated with early diabetic nephropathy (EDN), glomerular DKD (GDKD) and tubular DKD (TDKD), respectively. A total of 1,241, 318 and 280 differentially expressed genes (DEGs) were identified for GSE30258, GSE30529, and GSE111154 respectively. Subsequently, 280 upregulated and 27 downregulated DEGs shared between the three GSE datasets were identified. Further analysis of the gene expression levels conducted on the hub genes revealed SPARC (Secreted Protein Acidic And Cysteine Rich), POSTN (periostin), LUM (Lumican), KNG1 (Kininogen 1), FN1 (Fibronectin 1), VCAN (Versican) and PTPRO (Protein Tyrosine Phosphatase Receptor Type O) having potential roles in DKD progression. FN1, LUM and VCAN were identified as upregulated genes for GDKD whereas the downregulation of PTPRO was associated with all three diseases. Both POSTN and SPARC were identified as the overexpressed putative biomarkers whereas KNG1 was found as downregulated in TDKD. Additionally, we also identified two drugs, namely pidorubicine, a topoisomerase inhibitor (LINCS ID- BRD-K04548931) and Polo-like kinase inhibitor (LINCS ID- BRD-K41652870) having the validated role in reversing the differential gene expression patterns observed in the three GSE datasets used. Collectively, this study aids in the understanding of the molecular drivers, critical genes and pathways that underlie DKD initiation and progression.

Model learning to identify systemic regulators of the peripheral circadian clock.

MOTIVATION: Personalized medicine aims at providing patient-tailored therapeutics based on multi-type data toward improved treatment outcomes. Chronotherapy that consists in adapting drug administration to the patient's circadian rhythms may be improved by such approach. Recent clinical studies demonstrated large variability in patients' circadian coordination and optimal drug timing. Consequently, new eHealth platforms allow the monitoring of circadian biomarkers in individual patients through wearable technologies (rest-activity, body temperature), blood or salivary samples (melatonin, cortisol) and daily questionnaires (food intake, symptoms). A current clinical challenge involves designing a methodology predicting from circadian biomarkers the patient peripheral circadian clocks and associated optimal drug timing. The mammalian circadian timing system being largely conserved between mouse and humans yet with phase opposition, the study was developed using available mouse datasets. RESULTS: We investigated at the molecular scale the influence of systemic regulators (e.g. temperature, hormones) on peripheral clocks, through a model learning approach involving systems biology models based on ordinary differential equations. Using as prior knowledge our existing circadian clock model, we derived an approximation for the action of systemic regulators on the expression of three core-clock genes: Bmal1, Per2 and Rev-Erbα. These time profiles were then fitted with a population of models, based on linear regression. Best models involved a modulation of either Bmal1 or Per2 transcription most likely by temperature or nutrient exposure cycles. This agreed with biological knowledge on temperature-dependent control of Per2 transcription. The strengths of systemic regulations were found to be significantly different according to mouse sex and genetic background.

Iguratimod ameliorates nephritis by modulating the Th17/Treg paradigm in pristane-induced lupus.

OBJECTIVE: Iguratimod, an anti-rheumatic drug, has been widely used in the treatment of rheumatoid arthritis, but is still at an investigative stage for treatment of systemic lupus erythematosus (SLE). We examined the therapeutic effects of iguratimod and the mechanism underlying the efficacy in murine lupus model. METHODS: Pristane-induced lupus model of BALB/c mice (PI mice) were treated with iguratimod and mycophenolate mofetil. Proteinuria, anti-dsDNA antibodies and immunoglobulins production were measured. Renal pathology was evaluated. The percentage of Th17 and Treg cells in spleen and the expression of cytokines and mRNAs related to Th17 and Treg cells was analyzed. RESULTS: Iguratimod attenuated the severity of nephritis in PI mice in a dose-dependent manner. Proteinuria was continuously decreased and pathology of glomerulonephritis and tubulonephritis was significantly reduced along with reduction of glomerular immune complex deposition. Also, serum anti-dsDNA and total IgG and IgM levels were reduced by iguratimod in mice. It is worth mentioning that the efficacy of the 30 mg/kg/d iguratimod dose is comparable to, or even better than, 100 mg kg/d of mycophenolate mofetil. Furthermore, the percentage of Th17 cells was found decreased and the percentage of Treg cells increased. ROR-γt mRNA and serum cytokines (IL-17A and IL-22) of Th17 cells decreased accordingly. By contrast, Foxp3 mRNA and cytokines (TGF-ß and IL-10) of Treg cells increased. CONCLUSION: Iguratimod ameliorates nephritis of SLE and modulates the Th17/Treg ratio in murine nephritis of SLE, suggesting that Iguratimod could be an effective drug in treatment of SLE.

The Effectiveness of Yoga on Cancer-Related Fatigue: A Systematic Review and Meta-Analysis.

PROBLEM IDENTIFICATION: The aim of this article is to evaluate the effectiveness of yoga on cancer-related fatigue (CRF) in patients undergoing chemotherapy and/or radiation therapy. LITERATURE SEARCH: Relevant English and Chinese articles were retrieved from medical databases and included in this analysis. Standardized critical appraisal instruments from the Joanna Briggs Institute were adopted for the quality assessment. DATA EVALUATION: 16 randomized controlled trials met the inclusion criteria. SYNTHESIS: Yoga interventions had a positive effect in reducing CRF among patients undergoing chemotherapy and/or radiation therapy, but the adherence to yoga was low. Mixed types of yoga, in addition to supervised and self-practicing strategies, were associated with increased patient adherence and improved CRF. IMPLICATIONS FOR PRACTICE: Yoga appears to be a safe and effective exercise for the management of CRF during chemotherapy and/or radiation therapy; however, additional high-quality studies are needed to define an optimal yoga intervention strategy.

Anticoagulation and Transjugular Intrahepatic Portosystemic Shunt for the Management of Portal Vein Thrombosis in Cirrhosis: A Prospective Observational Study.

INTRODUCTION: Current guidelines recommend anticoagulation as the mainstay of portal vein thrombosis (PVT) treatment in cirrhosis. However, because of the heterogeneity of PVT, anticoagulation alone does not always achieve satisfactory results. This study aimed to prospectively evaluate an individualized management algorithm using a wait-and-see strategy (i.e., no treatment), anticoagulation, and transjugular intrahepatic portosystemic shunt (TIPS) to treat PVT in cirrhosis. METHODS: Between February 2014 and June 2018, 396 consecutive patients with cirrhosis with nonmalignant PVT were prospectively included in a tertiary care center, of which 48 patients (12.1%) were untreated, 63 patients (15.9%) underwent anticoagulation, 88 patients (22.2%) underwent TIPS, and 197 patients (49.8%) received TIPS plus post-TIPS anticoagulation. The decision of treatment option mainly depends on the stage of liver disease (symptomatic portal hypertension or not) and degree and extension of thrombus. RESULTS: During a median 31.7 months of follow-up period, 312 patients (81.3%) achieved partial (n = 25) or complete (n = 287) recanalization, with 9 (3.1%) having rethrombosis, 64 patients (16.2%) developed major bleeding (anticoagulation-related bleeding in 7 [1.8%]), 88 patients (22.2%) developed overt hepatic encephalopathy, and 100 patients (25.3%) died. In multivariate competing risk regression models, TIPS and anticoagulation were associated with a higher probability of recanalization. Long-term anticoagulation using enoxaparin or rivaroxaban rather than warfarin was associated with a decreased risk of rethrombosis and an improved survival, without increasing the risk of bleeding. However, the presence of complete superior mesenteric vein thrombosis was associated with a lower recanalization rate, increased risk of major bleeding, and poor prognosis. DISCUSSION: In patients with cirrhosis with PVT, the individualized treatment algorithm achieves a high-probability recanalization, with low rates of portal hypertensive complications and adverse events.
