Blindness in Right Eyes after Enema: A Case of Klebsiella pneumoniae-Related Invasive Liver Abscess Syndrome with Endophthalmitis-Caused Blindness as the First Symptom.

We report a case of Klebsiella pneumoniae invasive liver abscess syndrome (KPILAS) with endophthalmitis-caused blindness as the first symptom after enema. The patient had diabetes, and his blood glucose was poorly controlled. She developed hematuria after four enemas for cosmetic purposes and later became blind. The eye discharge was cultured, which revealed a Klebsiella pneumoniae infection. B ultrasound did not show liver lesions, but computed tomography exhibited abscesses in the right lobe of the liver. Magnetic resonance imaging of the head indicated abscesses. These confirmed the diagnosis of invasive liver abscess syndrome. The patient was given ophthalmic and systemic anti-infection treatments, and her condition was effectively controlled. Unfortunately, the diseased eye still needed to be removed. This case underlines the necessity of avoiding unnecessary risky procedures (such as enemas) in vulnerable populations, the importance of early detection of invasive liver abscess syndrome, and the advantage of computed tomography in detecting liver abscesses.

Therapeutic application of traditional Chinese medicine in kidney disease: Sirtuins as potential targets.

Sirtuins are a family of NAD+ III-dependent histone deacetylases that consists of seven family members, Sirt1-Sirt7, which regulate various signalling pathways and are involved in many critical biological processes of kidney diseases. Traditional Chinese medicine (TCM), as an essential part of the global healthcare system, has multi-component and multi-pathway therapeutic characteristics and plays a role in preventing and controlling various diseases. Through ongoing collaboration with modern medicine, TCM has recently achieved many remarkable advancements in theoretical investigation, mechanistic research, and clinical applications related to kidney diseases. Therefore, a comprehensive and systematic summary of TCM that focuses on sirtuins as the intervention target for kidney diseases is necessary. This review introduces the relationship between abnormal sirtuins levels and common kidney diseases, such as diabetic kidney disease and acute kidney injury. Based on the standard biological processes, such as inflammation, oxidative stress, autophagy, mitochondrial homeostasis, and fibrosis, which are underlying kidney diseases, comprehensively describes the roles and regulatory effects of TCM targeting the sirtuins family in various kidney diseases.

Zi-Su-Zi decoction improves airway hyperresponsiveness in cough-variant asthma rat model through PI3K/AKT1/mTOR, JAK2/STAT3 and HIF-1α/NF-κB signaling pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: Cough-variant asthma (CVA) is one of the most common causes of chronic cough. Its pathogenesis is closely related to chronic airway inflammation and airway hyperresponsiveness. CVA belongs to the category of "wind cough" in Traditional Chinese medicine (TCM). Zi-Su-Zi decoction (ZSD) is a Chinese herbal formula that is clinically used for the treatment of cough and asthma, especially CVA. However, the mechanism of action remains unclear. AIM OF THE STUDY: In this study, we aimed to explore the potential mechanism by which ZSD improves CVA airway hyperresponsiveness. MATERIALS AND METHODS: The targets of ZSD in CVA were studied using a Network pharmacology. The main chemical components of ZSD were detected and analyzed using ultra-high-pressure liquid chromatography (UHPLC-MS/MS). In animal experiments, the rat model of CVA was established using Ovalbumin (OVA)/Aluminum hydroxide (AL(OH)3) sensitization. Moreover, the experiment also evaluated cough symptoms, percentage of eosinophils (EOS%), pulmonary function tests, histopathological sections, blood cytokine levels, mRNA and protein levels. RESULTS: The results showed that Network pharmacology suggested 276 targets of ZSD and CVA and found that ZSD treatment with CVA was closely related to the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway. UHPLC-MS/MS revealed that ZSD contained 52 main chemical components. Compared with the model group, the cough symptoms of the rats in the different ZSD concentration groups were relieved, the EOS% index was lowered, and body weight was increased. HE staining showed that ZSD reduced airway inflammation, edema and hyperplasia, thereby improving the pathological structure of lung tissue, and the effect of high-dose ZSD was especially significant. Our most important finding was that ZSD blocked the entry of hypoxia-inducible factor-1α (HIF-1α), signal transducer and activator of transcription-3 (STAT3) and nuclear factor kappa-B (NF-κB) into the nucleus by interfering with PI3K/AKT1/mechanistic target of rapamycin (mTOR), and janus kinase 2 (JAK2) signaling factors. Consequently, inhibiting the release of cytokines and immunoglobulin-E, thereby reducing airway hyperresponsiveness (AHR) and partially reverses airway remodeling. CONCLUSIONS: This study showed that ZSD can improve airway hyperresponsiveness and partially reverse airway remodeling by inhibiting the PI3K/AKT1/mTOR, JAK2/STAT3 and HIF-1α/NF-κB signaling pathways. Therefore, ZSD is an effective prescription for the treatment of CVA.

Non-pharmaceutical interventions in complementary and alternative medicine for insomnia in breast cancer survivors: a protocol for a systematic review and network meta-analysis.

INTRODUCTION: Insomnia has a high incidence in patients with breast cancer, which not only affects the quality of life of patients, but also affects the efficiency of later treatment and rehabilitation. Although the sedative and hypnotic drugs commonly used in clinical practice have a rapid onset of action, they are also accompanied by different degrees of sequelae, withdrawal effects and dependence and addiction. Complementary and alternative medicine (CAM) or complementary and integrative medicine, complementary integrative therapies, including natural nutritional supplement therapy, psychotherapy, physical and mental exercise, physiotherapy, have been reported to be used to treat cancer-related insomnia. Its clinical results are increasingly recognised and accepted by patients. However, the effectiveness and safety of these CAM are uneven, and there is no standard clinical application method. Therefore, in order to objectively evaluate the effects of different non-pharmaceutical interventions in CAM on insomnia, we will conduct a network meta-analysis (NMA) to explore the effects of different CAM interventions on improving sleep quality in patients with breast cancer. METHODS AND ANALYSIS: We will search all Chinese and English databases from the inception of the database to 31 December 2022. The databases include PubMed, Medline, Embase, Web of Science and Cochrane Central Register of Controlled Trials and the Chinese literature databases include CBM, CNKI, VIP, WANFANG. The Insomnia Severity Index and the Pittsburgh Sleep Quality Index will be considered as the primary outcomes in the study. STATA V.15.0 software will be used to conduct pairwise meta-analysis and NMA. Finally, we will use the recommended risk assessment tool RoB2 for risk and bias assessment, and use the Grading of Recommendations Assessment, Development and Evaluation evaluation method to evaluate the quality of evidence. ETHICS AND DISSEMINATION: Ethical approval will not be required because the study will not include the original information of participants. The results will be published in a peer-reviewed journal or disseminated in relevant conferences. PROSPERO REGISTRATION NUMBER: CRD42022382602.

Therapeutic potential of artemisinin and its derivatives in managing kidney diseases.

Artemisinin, an antimalarial traditional Chinese herb, is isolated from Artemisia annua. L, and has shown fewer side effects. Several pieces of evidence have demonstrated that artemisinin and its derivatives exhibited therapeutic effects on diseases like malaria, cancer, immune disorders, and inflammatory diseases. Additionally, the antimalarial drugs demonstrated antioxidant and anti-inflammatory activities, regulating the immune system and autophagy and modulating glycolipid metabolism properties, suggesting an alternative for managing kidney disease. This review assessed the pharmacological activities of artemisinin. It summarized the critical outcomes and probable mechanism of artemisinins in treating kidney diseases, including inflammatory, oxidative stress, autophagy, mitochondrial homeostasis, endoplasmic reticulum stress, glycolipid metabolism, insulin resistance, diabetic nephropathy, lupus nephritis, membranous nephropathy, IgA nephropathy, and acute kidney injury, suggesting the therapeutic potential of artemisinin and its derivatives in managing kidney diseases, especially the podocyte-associated kidney diseases.

Brain organoids are new tool for drug screening of neurological diseases.

At the level of in vitro drug screening, the development of a phenotypic analysis system with high-content screening at the core provides a strong platform to support high-throughput drug screening. There are few systematic reports on brain organoids, as a new three-dimensional in vitro model, in terms of model stability, key phenotypic fingerprint, and drug screening schemes, and particularly regarding the development of screening strategies for massive numbers of traditional Chinese medicine monomers. This paper reviews the development of brain organoids and the advantages of brain organoids over induced neurons or cells in simulated diseases. The paper also highlights the prospects from model stability, induction criteria of brain organoids, and the screening schemes of brain organoids based on the characteristics of brain organoids and the application and development of a high-content screening system.

Tibial nerve electrical stimulation for fecal incontinence: a systematic review and meta-analysis.

Tibial nerve stimulation (TNS) therapy is widely used to treat fecal incontinence (FI), but still, some controversy exists. This study aimed to determine whether TNS could improve FI from different evaluation angles. A systematic review and meta-analysis were conducted to provide indirect evidence of TNS treatment for FI. We searched for the original studies in PubMed, Embase, Web of Science, Ebsco Medline, Ovid Medline, and Cochrane Central Register of Controlled Trials published before November 31, 2021. The standardized mean difference was the efficacy analysis statistic, and the effect was expressed by the 95% confidence interval (CI). For the case series, we calculated the mean difference of the number of patients evaluated at baseline and last follow-up. Four randomized controlled trials (RCTs, four hundred and sixty participants) and eighteen case series (eight hundred and thirty-eight participants) were included in the study. The results of the RCTs showed that the number of weekly episodes of FI significantly reduced in the TNS group compared with the sham stimulation group. The results of the case series showed that TNS reduced the number of patients with FI per week. The Cleveland Clinic Florida FI Score significantly reduced. The post-treatment results of maximum squeeze pressure and maximum resting pressure were significantly different from baseline. This study showed that TNS to some extent reduced the number of patients with FI, reduced clinical symptoms, and improved anal physiological function. Despite the low quality of overall evidence, TNS still shows some potential as a safe treatment for FI.

Network and Experimental Pharmacology to Decode the Action of Wendan Decoction Against Generalized Anxiety Disorder.

Objective: The mechanism of Wendan Decoction (WDD) against Generalized Anxiety Disorder (GAD) was predicted by network pharmacology and validated by in vivo and in vitro experiments. Methods: The targets of WDD for the treatment of GAD were obtained by a search of online databases. Further, PPI network and KEGG enrichment were used to identify the key targets and pathways. Ultimately, these key targets and pathways were validated by in vivo experiments on GAD mice modeled by repeated restraint stress (RRS) and in vitro experiments on inflammatory factor stimulated BV-2 cells. Results: Through searching the databases, the 137 ingredients of WDD that correspond to 938 targets and 4794 targets related to GAD were identified. Among them, 569 overlapping targets were considered as the therapeutic targets of WDD for GAD. PPI analysis showed that the inflammation-related proteins IL-6, TNF, SRC and AKT1 were the key targets, and KEGG enrichment suggested that PI3K/AKT and MAPK signaling pathways were key pathways of WDD in the treatment of GAD. In vivo experiments, RRS mice exhibited abnormality in behavioristics in open field test (OFT) and elevated plus maze (EPM) and increases in serum corticosterone and the percentage of lymphocytes positive for IL-6 in peripheral blood. These abnormal changes can be reversed by WDD and the positive control drug paroxetine. In vitro experiments, WDD can inhibit IL-6 induced activation of PI3K/AKT and MAPK signaling pathways in BV2 cells, and suppress the ensuing release of inflammatory factors TNF-α, IL-1ß and PGE2, and showed a dose-dependent effect. Conclusion: WDD is able to resist GAD by relieving inflammatory response in peripheral and central system.

Effect of Acupuncture on the Cognitive Control Network of Patients with Knee Osteoarthritis: Study Protocol for a Randomized Controlled Trial.

Purpose: Abnormal central nervous system function is the key central pathological factor leading to chronic pain in patients with knee osteoarthritis (KOA). Acupuncture can effectively relieve the pain of KOA patients. However, the central nervous mechanism of acupuncture treating KOA is not fully understood. This trial will use functional magnetic resonance imaging (fMRI) analysis techniques to investigate the potential central nervous mechanism of acupuncture treatment of KOA. Materials and Methods: A total of 108 patients will be randomized (in a 1:1:1 ratio) into three groups, this trial will include 4-week treatment, patients in groups A and B will receive 20 acupuncture and sham acupuncture sessions, respectively, patients in group C will not receive any intervention, and all patients will receive fMRI scans before and after the intervention. The Western Ontario and McMaster Universities Osteoarthritis Index score (WOMAC) will be the primary clinical outcome. Then, we will explore the functional changes of the cognitive control network (CCN) in the brains of KOA patients through whole brain functional connectivity (FC) analysis and seed-based functional connectivity (sFC) analysis. Pearson correlation coefficient will be used to analyze the relationship between the improved value of the clinical correlation scale and the change of fMRI data. Discussion: This trial will analyze the efficacy of verum acupuncture, sham acupuncture and the waiting-list for KOA and explore the activity of the CCN in three groups of patients by fMRI, so as to reveal the central nervous mechanisms of acupuncture in the treatment of KOA. Study Registration: This study is approved by the Ethics Committee of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine (No: 2019HL-133-01) and registered in the Chinese Clinical Trial Registry, ChiCTR2000038554.

Transurethral plasmakinetic resection versus enucleation for benign prostatic hyperplasia: comparison of intraoperative safety profiles based on endoscopic surgical monitoring system.

OBJECTIVE: To compare the intraoperative safety profiles of transurethral plasmakinetic resection of the prostate (PK-TURP) with transurethral plasmakinetic endoscopic enucleation of the prostate (PK-EEP) in the treatment of benign prostatic hyperplasia (BPH) based on endoscopic surgical monitoring system (ESMS). METHODS: A total of 128 patients who were diagnosed with BPH were stratified based on prostate volume (PV) and accepted PK-EEP or PK-TURP treatment at 1:1 ratio. The ESMS as a novel method was used to monitor blood loss and fluid absorption during the operation. Clinical parameters such as intraoperative blood loss volume, fluid absorption volume, operation time, tissue weight of resection, preoperative and postoperative red blood cell count (RBC), hemoglobin concentration (HB), hematocrit (HCT), electrolyte, postoperative bladder irrigation time, indwelling catheter time, hospital stay time and other associated complications were documented and compared between two groups. RESULTS: No significant differences in majority of baseline characteristics were observed among patients with different prostate volumes between two surgical methods. For patients with prostate volume < 40 ml, the average operation time of patients who received PK-EEP treatment was much more than those who received PK-TURP (P = 0.003). On the other hand, for patients with prostate volume > 40 ml, the PK-TURP surgery was associated with a significant increase in intraoperative blood loss (P = 0.021, in PV 40-80 ml group; P = 0.014, in PV > 80 ml group), fluid absorption (P = 0.011, in PV 40-80 ml group; P = 0.006, in PV > 80 ml group) and postoperative bladder irrigation time as well as indwelling catheter time but decrease in resected tissue weight compared to the PK-EEP treatment. CONCLUSION: The ESMS plays an important role in comparison of intraoperative safety profiles between PK-TURP and PK-EEP. Our data suggest that PK-TURP treatment is associated with a decreased operation time in patients with prostate volume < 40 ml and the PK-EEP treatment is associated with decreased intraoperative blood loss, fluid absorption and increased tissue resection for patients with prostate volume > 40 ml. Our results indicate that the size of prostate should be considered when choosing the right operation method.

Moxibustion may delay the aging process of Wistar rats by regulating intestinal microbiota.

As one of the important treatments of health care and anti-aging in traditional Chinese medicine (TCM), moxibustion has been proved to have the effects of scavenging free radicals, anti-oxidation, reducing inflammatory reaction, regulating immunity and so on. Recent studies have shown that intestinal microbiota affect the process of aging. The relationship between aging, moxibustion and intestinal microbiota is still unclear. In this study, we explored the effects of moxibustion at Guanyuan (RN4) acupoint on intestinal microbiota, short-chain fatty acids and immunological characteristics of young and elder female Wistar rats to explore the relationship between aging, moxibustion and intestinal microbiota. Six 12-week-old female Wistar rats were young group (Y), and twelve 36-week-old female Wistar rats were randomly divided into elder group (C) and moxibustion group (M). The rats in M group were received mild moxibustion at Guanyuan (RN4) acupoint, 20 min/d for 40 days. The rats in Y group and C group were not given any therapeutic intervention. The results showed that moxibustion increased the abundance of intestinal probiotics (mainly Lactobacillus) and the level of short chain fatty acids, the microcirculation blood flow around Guanyuan (RN4) acupoint was also significantly improved in elder rats. In addition, the expression of MyD88, MAPK, TRAF6, NF-κB in intestinal tissue was down-regulated, and the levels of inflammatory cytokines in intestinal were decreased.

Anti-pseudo-allergic components in licorice extract inhibit mast cell degranulation and calcium influx / 中国天然药物

Pseudo-allergic reactions (PARs) widely occur upon application of drugs or functional foods. Anti-pseudo-allergic ingredients from natural products have attracted much attention. This study aimed to investigate anti-pseudo-allergic compounds in licorice. The anti-pseudo-allergic effect of licorice extract was evaluated in rat basophilic leukemia 2H3 (RBL-2H3) cells. Anti-pseudo-allergic compounds were screened by using RBL-2H3 cell extraction and the effects of target components were verified further in RBL-2H3 cells, mouse peritoneal mast cells (MPMCs) and mice. Molecular docking and human MRGPRX2-expressing HEK293T cells (MRGPRX2-HEK293T cells) extraction were performed to determine the potential ligands of MAS-related G protein-coupled receptor-X2 (MRGPRX2), a pivotal target for PARs. Glycyrrhizic acid (GA) and licorice chalcone A (LA) were screened and shown to inhibit Compound48/80-induced degranulation and calcium influx in RBL-2H3 cells. GA and LA also inhibited degranulation in MPMCs and increase of histamine and TNF-α in mice. LA could bind to MRGPRX2, as determined by molecular docking and MRGPRX2-HEK293T cell extraction. Our study provides a strong rationale for using GA and LA as novel treatment options for PARs. LA is a potential ligand of MRGPRX2.

A Network Pharmacology to Explore the Mechanism of Astragalus Membranaceus in the Treatment of Diabetic Retinopathy.

BACKGROUND: Diabetic retinopathy (DR) includes a series of typical lesions affected by retinal microvascular damage caused by diabetes mellitus (DM), which not only seriously damages the vision, affecting the life's quality of patients, but also brings a considerable burden to the family and society. Astragalus Membranaceus (AM) is a commonly used medicine in clinical therapy of eye disorders in traditional Chinese medicine (TCM). In recent years, it is also used for treating DR, but the specific mechanism is unclear. Therefore, this study explores the potential mechanism of AM in DR treatment by using network pharmacology. METHODS: Based on the oral bioavailability (OB) and drug likeness (DL) of two ADME (absorption, distribution, metabolism, excretion) parameters, Traditional Chinese Medicine Systems Pharmacology Database (TCMSP), Swiss Target Prediction platform, GeneCards, and OMIM database were used to predict and screen the active compounds of AM, the core targets of AM in DR treatment. The Metascape data platform was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis on the core targets. RESULTS: 24 active compounds were obtained, such as quercetin, kaempferol, and astragaloside IV. There were 169 effective targets of AM in DR treatment, and the targets were further screened and finally, 38 core targets were obtained, such as VEGFA, AKT1, and IL-6. EGFR tyrosine kinase inhibitor resistance, AGE-RAGE signaling pathway in diabetic complications, PI3K-Akt signaling pathway, and other metabolic pathways participated in oxidative stress, cell apoptosis, angiogenesis signal transduction, inflammation, and other biological processes. CONCLUSION: AM treats DR through multiple compounds, multiple targets, and multiple pathways. AM may play a role in the treatment of DR by targeting VEGFA, AKT1, and IL-6 and participating in oxidative stress, angiogenesis, and inflammation.

Curcuma's extraction attenuates propranolol-induced psoriasis like in mice by inhibition of keratin, proliferating cell nuclear antigen and toll-like receptor expression.

Curcuma was the dried rhizomes of Curcuma kwangsiensis S.G. Lee et C.F. Liang (Chinese name: e zhu), have been used in China for thousands of years. There are some reports have shown that curcumin, the major component of curcuma, has a good curative effect on psoriasis, but the mechanism is still unknown, so the present study was designed to investigate the effect of curcuma's extraction on psoriasis-like mouse, and to explore the mechanisms of therapy. First, we observed that curcuma's extractions effect on mitosis of mouse vaginal epithelial cells; then making psoriasis like model and measuring the score of skin damage on days 7 and 14; finally, we observed the expression of immune factors (CK14, CK16, CK17, PCNA, TLR-2, TLR-4, TLR-9) in propranolol induced psoriasis like rats. Curcuma's extraction prohibited the mitosis of mouse vaginal epithelial cells; curcuma's extractions have a significantly efficacy and dose dependent inhibition on imiquimod induced psoriasis like rats; and the expression of immune factors (CK14, CK16, CK17, PCNA, TLR-2, TLR-4, TLR-9) was decreasing in the curcuma's extraction treated groups compared with normal groups. Our research proved that curcuma's extractions have a significantly efficacy on psoriasis like rats, thus, curcuma's extractions can be a potential novel treatment for psoriasis. Furthermore, the expression of immune factors was decreasing after treatment with curcuma's extraction suggest us cytokines has strong relation with the mechanism of therapy for psoriasis. Our results contribute towards validation of curcuma in the treatment of psoriasis and other joint disorders.

Traditional Chinese medicine Xiaosheng Powder for dry eye disease: A protocol for systematic review and meta analysis.

BACKGROUND: Dry eye disease (DED) has shown a significant increase in recent years, which seriously affects people's work and life. Xiaosheng Powder, a traditional Chinese medicine decoction, has been widely used in treating DED. However, there is no systematic review of the results of the study on this therapeutic effect. The purpose of this review is to evaluate the effectiveness and safety of Xiaosheng Powder in the treatment of DED. METHODS AND ANALYSIS: The electronic databases to be searched will include MEDLINE (PubMed), Cochrane Central Register of Controlled Trials in the Cochrane Library, Excerpta Medica Database, China National Knowledge Infrastructure, China Scientific Journal Database, Wanfang Database and Chinese Biomedical Literature Database. Papers in English or Chinese published from inception to 2020 will be included without any restrictions. Improvement in Ocular Surface Disease Index will be assessed as the primary outcomes. Tear break-up time, Schirmer I test, fluorescent, adverse events, and the recurrence rate after at least 3 months of the treatment will be evaluated as secondary outcomes. We will conduct a meta-analysis of randomized controlled trial if possible. The methodological qualities, including the risk of bias, will be evaluated using the Cochrane risk of bias assessment tool, while confidence in the cumulative evidence will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. ETHICS AND DISSEMINATION: It is not necessary for a formal ethical approval because the data is not individualized. The results of this review will offer implications for the use of Xiaosheng Powder as a treatment for DED. This knowledge will inform recommendations by ophthalmologist and researchers who are interested in the treatment of DED. The findings of this systematic review will be disseminated through peer-reviewed publications and conference presentations. TRAIL REGISTRATION NUMBER: PROSPERO CRD42020147709.

Application of multi-dimensional and multi-informational (MD-MI) integrated xanthine oxidase and superoxide anion fingerprint in quality evaluation of Scutellariae Radix.

A multi-hyphenated analytical method that was successfully established in previous research was applied to quality evaluation of traditional Chinese medicine (TCM) to verify its feasibility in complex systems. Scutellariae Radix (SR), which significantly protects against oxidative damage from ischemia and reperfusion, was selected as the TCM for this study. A dual-activity detection system based on xanthine oxidase (XOD) inhibition and superoxide anion (O2-) scavenging activity was used to generate a multi-dimensional-multi-informational (MD-MI) integrated fingerprint of SR. Combined with HPLC-ESI-Q-TOF-MS analysis, 17 active compounds in SR were tentatively identified by comparison with reference substances or literature data. The quality of SR from different habitats was comprehensively and systematically evaluated in respect of chemical composition, XOD inhibition and O2- scavenging activity. It was confirmed that SR contains many antioxidants and XOD inhibitory substances with diverse functions. Among them, baicalin, norwogonin-7-O-glucuronide and baicalein are the main contributors to direct antioxidant activity. Acteoside, 5,7,2',5'-tetrahydroxy-8,6'-dimethoxy flavone, baicalin and baicalein are the main XOD inhibitory components of SR. Comprehensive analysis found that the antioxidant activity of SR from Gansu Province was superior to that from other provinces in terms of both XOD inhibition and O2- scavenging activity. It has been demonstrated that the method is capable of analyzing complex TCM matrices, and can provide a useful reference for establishing quality control of TCM from the perspective of MD-MI.

Efficacy of acupuncture at three nasal acupoints plus acupoint application for perennial allergic rhinitis: A multicenter, randomized controlled trial protocol.

BACKGROUND: Many studies have shown the potential therapeutic effect of acupuncture on allergic rhinitis. Most of these studies were limited by low-quality evidence. Preliminary experiments showed that the use of acupuncture at three nasal acupoints plus acupoint application (AAP) achieves a more persistent effect in the treatment of perennial allergic rhinitis than acupuncture alone. In this study, a multicenter, single-blind, randomized controlled trial will be performed, in which acupuncture at nonmeridian acupoints and sham AAP will be used as the control group to evaluate the effect of AAP through long-term observation. METHODS: The trial is designed on the basis of the Consolidated Standards of Reporting Trials 2010 guidelines and Standards for Reporting Interventions in Controlled Trials of Acupuncture. A total of 120 participants with perennial allergic rhinitis will be randomly assigned to a treatment or control group. A specially appointed investigator will be in charge of randomization. The participants in the treatment group will be treated with acupuncture at EX-HN3, LI20, and EX-HN8 thrice per week for a total of 12 sessions. In addition, they will undergo AAP at DU14, BL13, EX-BI, and RN22. The participants in the control group will be treated with sham AAP. The primary outcome will be the change in the Total Nasal Symptom Score from baseline to the completion of 4-week treatment. Secondary outcomes include changes in visual analog scale and total non-nasal symptom scores from baseline to the second and fourth weeks of treatment, as well as 1, 3, and 6 months after the completion of treatment. Peripheral blood IL-4, IL-5, IL-6, IL-8, and IL-10 levels will be measured, and any side effects related to treatment will be observed and recorded. DISCUSSION: It is expected that this randomized clinical trial will provide evidence to determine the effects of AAP compared with acupuncture at nonmeridian acupoints and sham AAP, particularly the long-term effect. These findings will help improve the clinical application of this technique. TRIAL REGISTRATION: Acupuncture-Moxibustion Clinical Trial Registry AMCTR-ICR-18000179. Registered on 12 April 2018.

Outcome of non-vitamin K oral anticoagulants in the treatment of left atrial/left atrial appendage thrombus in patients with nonvalvular atrial fibrillation.

BACKGROUND: Data comparing dabigatran with rivaroxaban regarding the resolution of left atrial/left atrial appendage (LA/LAA) thrombus in patients with nonvalvular atrial fibrillation (AF) are scarce. This study aimed to compare the efficacy and safety of dabigatran vs rivaroxaban regarding the resolution of LA/LAA thrombus in patients with nonvalvular AF. METHODS: This retrospective study enrolled nonvalvular AF patients scheduled to undergo catheter ablation or cardioversion in Shanghai Ruijin Hospital between January 2014 and January 2019. Altogether, 34 patients with LA/LAA thrombus detected by transesophageal echocardiography (TEE) were enrolled. Among them, 12 patients were treated with dabigatran 150 mg bid and the other 22 with rivaroxaban 20 mg qd. Follow-up TEE was performed within greater than or equal to 3 weeks to less than 6 months of the initial TEE to evaluate the resolution of the LA/LAA thrombus. RESULTS: Baseline patient characteristics were similar in the two groups. Overall, 18 patients (81.8%) in the rivaroxaban group had complete thrombus resolution after 70.3 ± 22.1 treatment days, and 10 patients (83.3%) in the dabigatran group had complete thrombus resolution after 69.3 ± 47.9 treatment days. There was no significant difference between the groups (P = .6). TEE showed that the average length, width, and area of thrombus significantly decreased in both groups after treatment, although there was no significant difference in the amount of change in these parameters between the two groups after treatment (P = .6). Undissolved thrombus in two patients in the rivaroxaban group did dissolve after switching to dabigatran. CONCLUSIONS: The results suggest that both dabigatran and rivaroxaban are potential options for treating LA/LAA thrombus in patients with nonvalvular AF. Dabigatran could be an alternative option for the resolution of LA/LAA thrombus resistant to rivaroxaban.

Maresin-1 Inhibits Oxidative Stress and Inflammation and Promotes Apoptosis in a Mouse Model of Caerulein-Induced Acute Pancreatitis.

BACKGROUND This study aimed to investigate the effects of maresin-1 (MaR1) in a mouse model of caerulein-induced acute pancreatitis (AP). MATERIAL AND METHODS Fifty C57BL/6 mice with caerulein-induced AP were divided into the untreated control group (N=10), the untreated AP model group (N=10), the MaR1-treated (low-dose, 0.1 µg) AP model group (N=10), the MaR1-treated (middle-dose, 0.5 µg) AP model group (N=10), and the MaR1-treated (high-dose, 1 µg) AP model group (N=10). Enzyme-linked immunoassay (ELISA) measured serum levels of amylase, lipase, tumor necrosis factor-alpha (TNF-alpha), interleukin-1ß (IL-1ß), and IL-6 and mRNA was measured by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Malondialdehyde (MDA), protein carbonyls, superoxide dismutase (SOD), and the ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) were measured. Histology of the pancreas included measurement of acinar cell apoptosis using the terminal-deoxynucleotidyl transferase-mediated nick end-labeling (TUNEL) assay. Western blot measured Toll-like receptor 4 (TLR4), MyD88, and phospho-NF-kappaB p65, and apoptosis-associated proteins Bcl-2, Bax, cleaved caspase-3, and cleaved caspase-9. RESULTS Following treatment with MaR1, serum levels of amylase, lipase, TNF-alpha, IL-1ß, and IL-6 decreased, MDA and protein carbonyl levels decreased, SOD and the GSH/GSSG ratio increased in a dose-dependent manner. In the MaR1-treated AP mice, inflammation of the pancreas and the expression of inflammatory cytokines, pancreatic acinar cell apoptosis, Bcl-2 expression, and expression of TLR4, MyD88, and p-NF-kappaB p65 were reduced, but Bax, cleaved caspase-3, and cleaved caspase-9 expression increased. CONCLUSIONS In a mouse model of caerulein-induced AP, treatment with MaR1 reduced oxidative stress and inflammation and reduced apoptosis.
