TaoHe ChengQi decoction ameliorates sepsis-induced cardiac dysfunction through anti-ferroptosis via the Nrf2 pathway.

BACKGROUND: Sepsis-induced cardiac dysfunction (SICD) is a serious complication of sepsis that is associated with increased mortality. Ferroptosis has been reported in the SICD. TaoHe ChengQi decoction (THCQD), a classical traditional Chinese medicinal formula, has multiple beneficial pharmacological effects. The potential effects of THCQD on the SICD remain unknown. PURPOSE: To investigate the effect of THCQD on SICD and explore whether this effect is related to the regulation of myocardial ferroptosis through nuclear factor erythroid 2-related factor 2 (Nrf2) activation. METHODS: We induced sepsis in a mouse model using cecal ligation and puncture (CLP) and administered THCQD (2 and 4 g/kg) and dexamethasone (40 mg/kg). Mice mortality was recorded and survival curves were plotted. Echocardiography, hematoxylin and eosin staining, and analysis of serum myocardial injury markers and inflammatory factors were used to evaluate cardiac pathology. Myocardial ferroptosis was detected by quantifying specific biomarker content and protein levels. Through HPLC-Q-Exactive-MS analysis, we identified the components of the THCQD. Network pharmacology analysis and Cellular Thermal Shift Assay (CETSA) were utilized to predict the targets of THCQD for treating SICD. We detected the expression of Nrf2 using Western blotting or immunofluorescence. An RSL3-induced ferroptosis model was established using neonatal rat cardiomyocytes (NRCMs) to further explore the pharmacological mechanism of THCQD. In addition to measuring cell viability, we observed changes in NRCM mitochondria using electron microscopy and JC-1 staining. NRF2 inhibitor ML385 and Nrf2 knockout mice were used to validate whether THCQD exerted protective effects against SICD through Nrf2-mediated ferroptosis signaling. RESULTS: THCQD reduced mortality in septic mice, protected against CLP-induced myocardial injury, decreased systemic inflammatory response, and prevented myocardial ferroptosis. Network pharmacology analysis and CETSA experiments predicted that THCQD may protect against SICD by activating the Nrf2 signaling pathway. Western blotting and immunofluorescence showed that THCQD activated Nrf2 in cardiac tissue. THCQDs consistently mitigated RSL3-induced ferroptosis in NRCM, which is related to Nrf2. Furthermore, the pharmacological inhibition of Nrf2 and genetic Nrf2 knockout partially reversed the protective effects of THCQD on SICD and ferroptosis. CONCLUSION: The effect of THCQD on SICD was achieved by activating Nrf2 and its downstream pathways.

Emergence of Antifungal Resistant Subclades in the Global Predominant Phylogenetic Population of Candida albicans.

Candida albicans remains the most common species causing invasive candidiasis. In this study, we present the population structure of 551 global C. albicans strains. Of these, the antifungal susceptibilities of 370 strains were tested. Specifically, 66.6% of the azole-nonsusceptible (NS)/non-wild-type (NWT) strains that were tested belonged to Clade 1. A phylogenetic analysis, a principal components analysis, the population structure, and a loss of heterozygosity events revealed two nested subclades in Clade 1, namely, Clade 1-R and Clade 1-R-α, that exhibited higher azole-NS/NWT rates (75.0% and 100%, respectively). In contrast, 6.4% (21/326) of the non-Clade 1-R isolates were NS/NWT to at least 1 of 4 azoles. Notably, all of the Clade 1-R-α isolates were pan-azole-NS/NWT that carried unique A114S and Y257H double substitutions in Erg11p and had the overexpression of ABC-type efflux pumps introduced by the substitution A736V in transcript factor Tac1p. It is worth noting that the Clade 1-R and Clade 1-R-α isolates were from different cities that are distributed over a large geographic span. Our study demonstrated the presence of specific phylogenetic subclades that are associated with antifungal resistance among C. albicans Clade 1, which calls for public attention on the monitoring of the future spread of these clones. IMPORTANCE Invasive candidiasis is the most common human fungal disease among hospitalized patients, and Candida albicans is the predominant pathogen. Considering the large number of infected cases and the limited alternative therapies, the azole-resistance of C. albicans brings a huge clinical threat. Here, our study suggested that antifungal resistance in C. albicans could also be associated with phylogenetic lineages. Specifically, it was revealed that more than half of the azole-resistant C. albicans strains belonged to the same clade. Furthermore, two nested subclades of the clade exhibited extremely high azole-resistance. It is worth noting that the isolates of two subclades were from different cities that are distributed over a large geographic span in China. This indicates that the azole-resistant C. albicans subclades may develop into serious public health concerns.

[Acupuncture and moxibustion for vascular dementia and its effect on serum VEGF and AChE].

OBJECTIVE: To observe the efficacy of Huayu Tongluo moxibustion combined with acupuncture at Jing-well points on the differentiated meridians and routine acupuncture for vascular dementia (VD) and its effect on serum levels of vascular endothelial growth factor (VEGF) and acetylcholinesterase (AChE). METHODS: A total of 60 patients with VD were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 2 cases dropped off). In the observation group, Huayu Tongluo moxibustion combined with acupuncture at Jing-well points on the differentiated meridians and routine acupuncture were adopted, Huayu Tongluo moxibustion was applied at Baihui (GV 20), Dazhui (GV 14) and Shenting (GV 24); acupuncture at Jing-well points on the differentiated meridians was applied at corresponding Jing-well points according to pattern of syndrome; routine acupuncture was applied at Baihui (GV 20), Sishencong (EX-HN 1), etc. Acupuncture and moxibustion were given once a day, 6 times a week for 4 weeks. In the control group, donepezil was prescribed for oral administration, 5 mg each time, once a day for 4 weeks. Before and after treatment, the scores of mini mental state examination (MMSE) and activities of daily living (ADL) were observed, and the serum levels of AChE and VEGF were detected in the two groups. RESULTS: Compared before treatment, the MMSE and ADL scores and serum level of VEGF were increased (P<0.05), the serum level of AChE was decreased (P<0.05) after treatment in the two groups. The MMSE and ADL scores after treatment in the observation group were higher than the control group (P<0.05). CONCLUSION: Huayu Tongluo moxibustion combined with acupuncture at Jing-well points on the differentiated meridians and routine acupuncture could improve cognitive function and activities of daily living, which may be related to the regulation of serum levels of VEGF and AChE.

Impact of orally administered tramadol combined with self-selected music on adult outpatients with burns undergoing dressing change: A randomized controlled trial.

OBJECTIVE: To investigate the effects of music and/or tramadol on pain and anxiety in burn outpatients undergoing dressing changes. DESIGN: Randomized controlled trial. SETTING: Burns and Plastic Reconstruction Unit. PARTICIPANTS: Patients (N=180) with burns on up to 10%-30% of the total body surface area (TBSA). INTERVENTIONS: The patients were randomly allocated to 4 equal-sized groups as follows: (1) tramadol group (TG), patients received 100mg of tramadol orally 20min before the dressing change; (2) music group (MG), patients listened to self-selected music during the dressing change; (3) music-plus-tramadol group (MTG), patients received tramadol and listened to self-selected music; and (4) control group (CG), patients received a routine dressing change only. All patients underwent the interventions once per day for 2days. MAIN OUTCOME MEASURES: McGill Pain Questionnaire Short Form (MPQ-SF) (primary outcome), McGill Pain Persian version of Burn Specific Pain Anxiety Scale (BSPAS) (primary outcome), and heart rate (HR) and overall patient satisfaction (secondary outcomes). RESULTS: The results showed that music-plus-tramadol group (MTG) had better outcomes with respect to pain and anxiety management during dressing changes. CONCLUSIONS: In comparison with music or tramadol alone, the integration of music and tramadol offers a secure and favorable treatment choice to relieve pain and anxiety, ultimately improving the satisfaction levels of burn outpatients during dressing changes.

Efficacy of acupuncture in the management of post-apoplectic aphasia: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Aim of this study was to evaluate the effectiveness of scalp, tongue, and Jin's 3-needle acupuncture for the improvement of postapoplectic aphasia. METHOD: PubMed, Cochrane, Embase databases were searched using index words to identify qualifying randomized controlled trials (RCTs). Meta-analyses of odds ratios (OR) or standardized mean differences (SMD) were performed to evaluate the outcomes between investigational (scalp / tongue / Jin's 3-needle acupuncture) and control (traditional acupuncture; TA and/or rehabilitation training; RT) groups. RESULTS: Thirty-two RCTs (1310 participants in investigational group and 1270 in control group) were included. Compared to TA, (OR 3.05 [95% CI: 1.77, 5.28]; p<0.00001), tongue acupuncture (OR 3.49 [1.99, 6.11]; p<0.00001), and Jin's 3-needle therapy (OR 2.47 [1.10, 5.53]; p = 0.03) had significantly better total effective rate. Compared to RT, scalp acupuncture (OR 4.24 [95% CI: 1.68, 10.74]; p = 0.002) and scalp acupuncture with tongue acupuncture (OR 7.36 [3.33, 16.23]; p<0.00001) had significantly better total effective rate. In comparison with TA/RT, scalp acupuncture, tongue acupuncture, scalp acupuncture with tongue acupuncture, and Jin's three-needling significantly improved ABC, oral expression, comprehension, writing and reading scores. CONCLUSION: As treatments to postapoplectic aphasia, scalp / tongue acupuncture and Jin's Three-needling are found better than TA and/or RT in yielding total effective rate and improving ABC, oral expression, comprehension, reading and writing scores.

Survival analysis of intraoperative blood salvage for patients with malignancy disease: A PRISMA-compliant systematic review and meta-analysis.

BACKGROUND: Intraoperative blood salvage as a blood-saving strategy has been widely used in surgery. Considering its theoretic risk of malignant tumor cells being reinfused and the corresponding blood metastases, the safety of intraoperative blood salvage in cancer surgery remains controversial. METHODS: Following the Preferred Reporting Items for Systemic Review and Meta-Analysis (PRISMA), we searched the Cochrane Library, MEDLINE and EMBASE to November 2017. We included only studies comparing intraoperative blood salvage with allogeneic blood transfusion. RESULTS: This meta-analysis included 9 studies with 4354 patients with 1346 patients in the intraoperative blood salvage group and 3008 patients in the allogeneic blood transfusion group. There were no significant differences in the 5-year overall survival outcome (odds ratio [OR] 1.12; 95% confidence interval [CI], 0.80-1.58), 5-year disease-free survival outcome (OR 1.08; 95% CI 0.86-1.35), or 5-year recurrence rate (OR 0.86; 95% CI 0.71-1.05) between the 2 study groups. Subgroup analysis also showed no significant differences in the 5-year overall survival outcome (OR 0.97; 95% CI 0.57-1.67) of hepatocellular carcinoma patients in liver transplantation. CONCLUSIONS: For patients with malignant disease, intraoperative blood salvage did not increase the tumor recurrence rate and had comparable survival outcomes with allogeneic blood transfusion.

The Effect of a Meditative Movement Intervention on Quality of Sleep in the Elderly: A Systematic Review and Meta-Analysis.

BACKGROUND/OBJECTIVES: Sleep disorders are one of the most common difficulties facing older people. Meditative movement interventions (MMIs), a new category of exercise integrating physical activity and meditation (e.g., t'ai chi, yoga, and qigong), may benefit older people with sleep problems. This systematic review synthesized the evidence on the effect of MMIs on older people's quality of sleep. METHODS: PubMed, EMBASE, CINAHL, PsycINFO, Scopus, the Cochrane Library, the China Science and Technology Journal Database (CSTJ) and the China National Knowledge Infrastructure (CNKI) were searched-from 1950 to March 2014-for randomized controlled trials. Articles were screened and selected by two researchers. Data were extracted from the included studies using specified forms. The same researchers independently evaluated the quality of each article. A meta-analysis was conducted to examine the pooled effect of MMI on sleep quality compared with the control groups. RESULTS: Fourteen of 1049 studies were included, involving 1225 participants. Interventions included t'ai chi, yoga, qigong, and multicomponent MMI and lasted 12-24 weeks. Ten studies had a low risk of bias. The interventions resulted in significantly better sleep quality scores than either active therapy or usual care/wait-list controls (standardized mean difference, -0.70;95% confidence interval, -0.96 to -0.43). Subgroup analyses revealed that the effect of MMI on sleep quality was not influenced by the type or duration of the intervention. However, pooled results of studies with intervention frequency of fewer than 3 times per week did not show a positive effect on sleep quality. Lower-quality studies had larger effect sizes than high-quality studies. No adverse events were reported. CONCLUSION: The current review demonstrated that MMI had a moderate effect on improving the quality of sleep for older people with sleep complaints. However, the evidence is inconclusive because of the varying study quality and MMI modalities. This study highlights the need for higher-quality randomized, controlled trials and more sufficient fidelity of intervention implementation to confirm the results. It also highlights the need for comparing the effectiveness of MMI on different subgroups of the elderly population.
