[Prevention and treatment of non-alcoholic fatty liver disease by regulation of mitochondrial function with Chinese medicine].

Non-alcoholic fatty liver disease(NAFLD), as a metabolic stress liver injury disease, is one of the most common chronic liver diseases, which seriously threatens people's health. The pathogenesis of NAFLD is very complex. A large number of studies show that the hepatic mitochondrial dysfunction leads to the disorder of hepatic glucose and lipid metabolism, oxidative stress, and inflammation, thus inducing hepatocyte apoptosis, which plays an important role in the progression of NAFLD. In recent years, researchers have begun to focus on developing drugs that slowed the progression of NAFLD by regulating the hepatic mitochondrial function. Chinese medicine has a good curative effect on the treatment of NAFLD, with the advantages of high safety and few side effects. Various studies have shown that Chinese medicine prevented and treated NAFLD by regulating the mitochondrial function. Therefore, this paper summarized the relationship between NAFLD and mitochondria, and the mechanism of Chinese medicine(single Chinese medicine, Chinese medicine monomer, and Chinese medicine compound prescription) in the prevention and treatment of NAFLD by regulating mitochondrial function. This paper is expected to provide references for clinical application of traditional Chinese medicine in the treatment of NAFLD by regulating mitochondrial function.

Astragalus mongholicus Bunge Water Extract Exhibits Anti-inflammatory Effects in Human Neutrophils and Alleviates Imiquimod-Induced Psoriasis-Like Skin Inflammation in Mice.

Neutrophils are the primary immune cells in innate immunity, which are related to various inflammatory diseases. Astragalus mongholicus Bunge is a Chinese medicinal herb used to treat various oxidative stress-related inflammatory diseases. However, there are limited studies that elucidate the effects of Astragalus mongholicus Bunge in human neutrophils. In this study, we used isolated human neutrophils activated by various stimulants to investigate the anti-inflammatory effects of Astragalus mongholicus Bunge water extract (AWE). Cell-free assays were used to examine free radicals scavenging capabilities on superoxide anion, reactive oxygen species (ROS), and nitrogen-centered radicals. Imiquimod (IMQ) induced psoriasis-like skin inflammation mouse model was used for investigating anti-psoriatic effects. We found that AWE inhibited superoxide anion production, ROS generation, and elastase release in human neutrophils, which exhibiting a direct anti-neutrophil effect. Moreover, AWE exerted a ROS scavenging ability in the 2,2'-Azobis (2-amidinopropane) dihydrochloride assay, but not superoxide anion in the xanthine/xanthine oxidase assay, suggesting that AWE exhibited anti-oxidation and anti-inflammatory capabilities by both scavenging ROS and by directly inhibiting neutrophil activation. AWE also reduced CD11b expression and adhesion to endothelial cells in activated human neutrophils. Meanwhile, in mice with psoriasis-like skin inflammation, administration of topical AWE reduced both the affected area and the severity index score. It inhibited neutrophil infiltration, myeloperoxidase release, ROS-induced damage, and skin proliferation. In summary, AWE exhibited direct anti-inflammatory effects by inhibiting neutrophil activation and anti-psoriatic effects in mice with IMQ-induced psoriasis-like skin inflammation. Therefore, AWE could potentially be a pharmaceutical Chinese herbal medicine to inhibit neutrophilic inflammation for anti-psoriasis.

The Effects of Biofeedback Training and Smartphone-Delivered Biofeedback Training on Resilience, Occupational Stress, and Depressive Symptoms among Abused Psychiatric Nurses.

Psychiatric ward (PW) nurses are at a higher risk to encounter workplace violence than are other healthcare providers, and many interventions have been developed to improve their mental health. We compared the effectiveness of biofeedback training (BT) and smartphone-delivered BT (SDBT) interventions on occupational stress, depressive symptoms, resilience, heart rate variability, and respiration rate in a sample of abused PW nurses. This was a quasi-experimental study. Structured questionnaires were administered before and six weeks after the intervention. Data were collected from April 2017 to October 2017. A total of 159 abused PW nurses were randomly assigned to BT, SDBT, and control groups, and 135 of them completed all processes of our protocol, with the study consisting of 119 females (88.1%) and 16 males (11.9%) and their age range being from 22 to 59 with the mean age of 35.61 and a standard deviation of 8.16. Compared to the controls, both the BT and the SDBT intervention groups experienced significant improvements in depressive symptoms, resilience, and respiration rate; and the SDBT group experienced significant reductions in occupational stress. Considering the cost, accessibility, restrictions time and space, SDBT be used as an effective intervention in people with resilience or occupational stress.

[A Nursing Experience Enhancing the Resilience Capacity of a Patient With Chronic Schizophrenia].

The article describes the author's nursing experience providing psychiatric homecare to a patient with chronic schizophrenia using the concept of resilience. Holistic nursing assessments were conducted via clinical observations during home visits every two weeks from May 24th to September 20th, 2018. Through these assessments, the main health problems of the patient were defined as ineffective self-health management, ineffective coping skills, and insufficient resilience. The nursing interventions implemented were designed to establish the patient's capacity to effectively and correctly self-manage health status, achieve emotional accommodation, and reduce parent-child conflicts. In order to enhance the resilience of the patient, the patient was guided to review important support resources over the course of illness, to detect the barriers of returning society, to apply the beneficial skills of health management, and then extend the status of employment and to enhance self-fulfillment.

Measuring Ochratoxin A Concentrations in Coffee Beverages with Immunoaffinity Columns and Ultra-Performance Liquid Chromatography/Tandem Mass Spectrometry.

This study developed and validated a method for measuring concentrations of ochratoxin A (OTA) in coffee beverages, not coffee beans. The new method involved extraction using immunoaffinity columns and ultra-performance LC (UPLC)-MS/MS using isotope-dilution techniques. The combination of a fused-core column and UPLC significantly shortened chromatographic time to 3 min compared to reported UPLC methods. The method was sensitive, with an LOD and LOQ of 0.52 and 1.73 pg/mL, respectively. Quantitative intraday (n = 4) and interday (n = 4) biases and RSD were both below 15%. The OTA levels in 40 samples of freshly brewed coffee from chain stores, 24 samples of canned ready-to-drink coffee, and 6 beverages made from instant coffee granules ranged from 1.60 to 93.2 pg/mL (90% positive), 6.00 to 131 pg/mL (100% positive), and 21.8 to 59.0 pg/mL (100% positive), respectively. Based on published tolerable daily intake, men and women in Taiwan should consume no more than 6.3 and 5.1 fifteen gram packages of instant coffee per day, respectively. Specific suggestions were not made for brewed coffee and canned coffee because of their large variation in OTA concentrations. This study should be more relevant to actual human exposure than those studying OTA in green, roasted, and ground coffee beans alone.

Comparison of intra-articular hyaluronic acid injections with transcutaneous electric nerve stimulation for the management of knee osteoarthritis: a randomized controlled trial.

OBJECTIVE: To compare the effects of intra-articular hyaluronic acid (HA; ARTZ) and transcutaneous electric nerve stimulation (TENS) in the treatment of patients with knee osteoarthritis. DESIGN: A prospective, randomized controlled trial. SETTING: Rehabilitation clinic of a teaching hospital. PARTICIPANTS: Patients with knee osteoarthritis (N=50; aged 51-80y) were randomly assigned to the HA group (n=27) or the TENS group (n=23). INTERVENTIONS: The HA group received intra-articular HA injection into the affected knee once a week for 5 consecutive weeks, and the TENS group received a 20- minute session of TENS 3 times a week for 4 consecutive weeks. MAIN OUTCOME MEASURES: The primary outcome measures used were the visual analog scale (VAS) for pain and the Lequesne index. The secondary outcome measures were range of motion of the knee, walking time, pain threshold, patient global assessment, and disability in activities of daily living. All subjects were assessed at baseline, and at 2 weeks, 2 months, and 3 months after the treatments were completed. RESULTS: The TENS group exhibited a significantly greater improvement in VAS than the HA group at 2 weeks' follow-up (4.17 ± 1.98 vs 5.31 ± 1.78, respectively; P=.03). In addition, the TENS group also exhibited a significantly greater improvement in the Lequesne index than the HA group at 2 weeks' follow-up (7.78 ± 2.08 vs 9.85 ± 3.54, respectively; P=.01) and at 3 months' follow-up (7.07 ± 2.85 vs 9.24 ± 4.04, respectively; P=.03). CONCLUSIONS: TENS with silver spike point electrodes was observed to be more effective than intra-articular HA injection for patients with knee osteoarthritis in improving the VAS for pain at 2 weeks' follow-up as well as the Lequesne index at 2 weeks' and 3 months' follow-up.

Disruption of glial function enhances electroacupuncture analgesia in arthritic rats.

Activated glia play a major role in mediating behavioral hypersensitive state following peripheral inflammation. Electroacupuncture is well known to relieve persistent inflammatory pain. The present study was undertaken to examine whether fluorocitrate, a glial metabolic inhibitor, could synergize electroacupuncture antagonizing thermal hyperalgesia and mechanical allodynia evoked by ankle joint inflammation. Monoarthritis of rat ankle joint was induced by an intra-articular injection of Complete Freund's Adjuvant (CFA). The paw withdrawal latency (PWL) from a thermal stimulus and paw withdrawal threshold (PWT) from von Frey hairs were measured in awake rats. Intrathecal (i.t.) injection of 1 nmol fluorocitrate markedly suppressed monoarthritis-induced thermal hyperalgesia and mechanical allodynia. Unilateral electroacupuncture stimulation of "Huantiao" (GB30) and "Yanglingquan" (GB34) acupuncture points (100/2 Hz alternation, 1-2-3 mA) significantly elevated the PWLs and PWTs for 45 min after cessation of electroacupuncture in monoarthritic rats. Co-application of 0.1 or 1 nmol fluorocitrate with electroacupuncture significantly potentiated electroacupuncture analgesia, although 0.1 nmol fluorocitrate alone had no effect on PWLs and PWTs in monoarthritic rats. These results suggested that electroacupuncture and disrupting glial function could synergistically antagonize inflammatory pain, which might provide a potential strategy for the treatment of arthritic pain.
