Collateral-Pricking and Bloodletting Cupping Combined with Electroacupuncture for Postherpetic Neuralgia: A Meta-Analysis.

Background: Acupuncture therapy has demonstrated significant efficacy in the treatment of postherpetic neuralgia, effectively alleviating pain intensity and enhancing patients' quality of life. However, the effectiveness of collateral-pricking and bloodletting cupping combined with electroacupuncture in the treatment of postherpetic neuralgia remains a subject of controversy. We aimed to assess the efficacy and safety of collateral-pricking and bloodletting cupping combined with electroacupuncture for postherpetic neuralgia. Methods: We identified relevant randomized controlled trials by conducting a comprehensive search in multiple databases: China National Knowledge Infrastructure, China Biomedical Literature, Wanfang Data, PubMed, Cochrane Central Register of Controlled Trials, Embase, and Web of Science. The outcome included efficacy rate, visual analog scale (VAS)scores and pittsburgh sleep quality index (PSQI) scores. We meticulously assessed the risk of bias in the included trials and performed a meta-analysis. Results: We analyzed 9 randomized controlled trials involving 639 patients. Collateral-pricking and bloodletting cupping combined with electroacupuncture achieved a significantly higher efficacy rate (risk ratio, 1.22 [95% CI, 1.13-1.31]; P < .001), reduced theVAS scores (standardized mean difference, -1.52 [95% CI, -2.26 to -0.79]; P < .001), and improved the PSQI scores (standardized mean difference, -2.31 [95% CI, -3.97 to -0.64]; P = .007) compared with the control groups. The subgroup analysis revealed that the combined treatment of collateral-pricking and bloodletting cupping and electroacupuncture had a significantly higher total effective rate compared with the carbamazepine, electroacupuncture, and pregabalin groups (P < .05). The total efficacy rate of the collateral-pricking and bloodletting cupping combined with electroacupuncture group was superior to that of the control group, irrespective of whether 2 or 3 courses were administered (P < .05). Conclusion: Existing evidence suggests that the combination of collateral-pricking and bloodletting cupping and electroacupuncture demonstrates efficacy in pain relief, improvement of sleep quality, and enhanced therapeutic outcomes for patients with postherpetic neuralgia. However, further validation through large-scale multicenter randomized controlled trials is warranted due to the limited quantity and quality of the included literature in this study.

Organic copper promoted copper accumulation and transport, enhanced low temperature tolerance and physiological health of white shrimp (Litopenaeus vannamei Boone, 1931).

This study was conducted to assess the effects of dietary copper source and level on hematological parameters, copper accumulation and transport, resistance to low temperature, antioxidant capacity and immune response of white shrimp (Litopenaeus vannamei Boone, 1931). Seven experimental diets with different copper sources and levels were formulated: C, no copper supplementation; S, 30 mg/kg copper in the form of CuSO4·5H2O; SO, 15 mg/kg copper in CuSO4·5H2O + 7.5 mg/kg copper in Cu-proteinate; O1, O2, O3 and O4, 10, 20, 30 and 40 mg/kg copper in the form of Cu-proteinate, respectively. A total of 840 shrimp (5.30 ± 0.04 g) were randomly distributed to 21 tanks (3 tanks/diet, 40 shrimp/tank). An 8-week feeding trial was conducted. The results showed that there was no significant difference in growth performance and whole shrimp chemical compositions among all groups. Compared with inorganic copper, dietary organic copper (O2 and O3) increased total protein, albumin, and glucose content of plasma, while decreased triglyceride and total cholesterol of plasma. Copper concentration in plasma and muscle and gene expression of metallothionein and copper-transporting ATPase 2 like in hepatopancreas were higher in shrimp fed organic copper (SO, O2, O3 and O4). The lowest mortality after low temperature (10 °C) challenge test was observed in the O2 and O3 groups. Organic copper (SO, O2, O3 and O4) significantly enhanced the antioxidant capacity (in terms of higher activities of total superoxide dismutase, copper zinc superoxide dismutase, catalase, glutathione peroxidase and total antioxidant capacity, lower malondialdehyde concentration of plasma, and up-regulated gene expression of superoxide dismutase, copper zinc superoxide dismutase, catalase and glutathione peroxidase of hepatopancreas). Organic copper (SO, O2, O3 and O4) enhanced the immune response (in terms of higher number of total hemocytes, higher activities of acid phosphatase, alkaline phosphatase, phenoloxidase, hemocyanin and lysozyme in plasma, and higher gene expressions of alkaline phosphatase, lysozyme and hemocyanin in hepatopancreas). Inorganic copper (Diet S) also had positive effects on white shrimp compared with the C diet, but the SO, O2, O3 and O4 diets resulted in better results, among which the O2 diet appeared to be the best one. In conclusion, organic copper was more beneficial to shrimp health than copper sulfate.

A LAMP-Based Toolbox Developed for Detecting the Major Pathogens Affecting the Production and Quality of the Chinese Medicinal Crop Aconitum carmichaelii.

Aconitum carmichaelii Debeaux is a traditional Chinese medicinal herb that has been utilized for approximately 2,000 years. However, as cultivation has increased, there have been more reports of A. carmichaelii infections caused by four major pathogenic fungal species, Fusarium oxysporum, F. solani, Mucor circinelloides, and Sclerotium rolfsii, resulting in increased disease incidences and limited production and quality. To detect these infections, we developed a LAMP-based toolbox in this study. The cytochrome c oxidase subunit 1 (cox1) gene, translation elongation factor-1α (EF-1α), internal transcribed spacer (ITS) regions of rDNA, and alcohol dehydrogenase 1 (ADH1) gene, respectively, were used to design species-specific LAMP primer sets for F. oxysporum, F. solani, S. rolfsii, and M. circinelloides. The results showed that the LAMP-based toolbox was effective at detecting pathogens in soil and plant materials. We also used this toolbox to investigate pathogen infection in the main planting regions of A. carmichaelii. Before harvesting, F. oxysporum, M. circinelloides, and S. rolfsii were commonly found in the planting fields and in infected A. carmichaelii plants. Therefore, the toolbox we developed will be useful for tracking these infections, as well as for disease control in A. carmichaelii.

Huangqi Guizhi Wuwu Decoction can prevent and treat oxaliplatin-induced neuropathic pain by TNFα/IL-1ß/IL-6/MAPK/NF-kB pathway.

OBJECTIVE: This study explored the effects and mechanisms of Huangqi Guizhi Wuwu Decoction on chemotherapy-induced neuropathic pain (CINP). METHODS: Bodyweight and related behavioral testing of the rat model were utilized to investigate the effects of Huangqi Guizhi Wuwu Decoction on CINP. ELISA was used to measure the levels of TNF-α, IL-1ß, and IL-6, in the serum of chronic CINP rats. Immunohistochemistry and Western blot analysis were performed to detect the expression of MAPK pathway related-proteins namely ERK1/2, p38, and JNK, and the expression of downstream essential proteins such as c-Fos, CREB, and NF-κB. RESULTS: Body weight and related behavioral testing of the rat model suggests that Huangqi Guizhi Wuwu Decoction can improve the slow weight gain of oxaliplatin-induced chronic CINP model rats and effectively prevent and treat oxaliplatin-induced regular CIPN rat model of hyperalgesia. It can also oppress the mechanical pain threshold, cold pain threshold, and heat pain threshold decreased. Furthermore, by ELISA, immunohistochemistry, and western blot analysis, we found that Huangqi Guizhi Wuwu Decoction can down-regulate the levels of TNF-α, IL-1ß, and IL-6 in the serum of chronic CINP rats induced by oxaliplatin. It also suppresses the expression of MAPK pathway related-proteins ERK1/2, p38, and JNK. This results in a decrease in the expression of downstream essential proteins, c-Fos, CREB, and Nf-κB. CONCLUSIONS: In conclusion, we found that Huangqi Guizhi Wuwu Decoction can combat nerve cell injury, reduce pain sensitization, and prevent and repair the damage of nerve cells in the oxaliplatin CINP model rats via TNFα/IL-1ß/IL-6/MAPK/NF-kB pathway.

Characteristics of Isolates of Pseudomonas aeruginosa and Serratia marcescens Associated With Post-harvest Fuzi (Aconitum carmichaelii) Rot and Their Novel Loop-Mediated Isothermal Amplification Detection Methods.

Fuzi (the lateral root of Aconitum carmichaelii Debx.) is a traditional Chinese medicine that is cultivated in more than eight provinces in China. However, it can be easily devastated by post-harvest rot, causing huge losses. Therefore, it is extremely important that the primary causal pathogens of post-harvest Fuzi rot are identified and appropriate detection methods for them are developed to prevent and control losses. In this study, two bacterial strains (X1 and X2) were isolated from rotten post-harvest Fuzi. Based on their morphological, physiological, and biochemical characteristics, housekeeping gene homologies, and matrix-assisted laser desorption ionization/time-of-flight mass spectrometry (MALDI-TOF MS) results, these isolates were identified as Pseudomonas aeruginosa and Serratia marcescens. The pathogenicities of these isolates were confirmed by fulfilling Koch's postulates demonstrating that they were post-harvest Fuzi rot pathogens. Two loop-mediated isothermal amplification (LAMP) methods targeting the gyrase B subunit (gyrB) gene of P. aeruginosa and the phosphatidylinositol glycan C (pigC) gene of S. marcescens were successfully developed, and it was found that the target genes were highly specific to the two pathogens. These LAMP methods were used to detect P. aeruginosa and S. marcescens in 46 naturally occurring Fuzi and their associated rhizosphere soil samples of unknown etiology. The two bacterial assays were positive in some healthy and rotten samples and could be accomplished within 1 h at 65°C without the need for complicated, expensive instruments. To our knowledge, this is the first report of P. aeruginosa and S. marcescens causing post-harvest Fuzi rot. The newly developed methods are expected to have applications in point-of-care testing for the two pathogens under different Fuzi planting procedures and will significantly contribute to the control and prevention of Fuzi rot.

Modulation of gastrointestinal bacterial in chronic atrophic gastritis model rats by Chinese and west medicine intervention.

Chronic atrophic gastritis (CAG) is well-known related with multiple pathogenic factors and normally therapies comprised by western or Chinese medicines. The present study was designed to identify the bacterial community characterized by 16S rRNA amplicon sequencing and determine the modulate affection of bacterial composition response western and Chinese medicine Qinghuayin (QHY) as well as antibiotic on model rats. The result shown the overall structure alteration of bacterial appeared under medicine intervened, antibiotic caused a marked depletion in bacterial diversity and richness. The enrichments of Firmicutes (85.1-90.7%) in antibiotic-free converts into Bacteroidetes (30.7-34.6%) in antibiotic-added model rat were demonstrated. Firmicutes as the most dominant phylum in antibiotic-free treatments and significantly decreased till 21.9-68.5% in antibiotic-added treatments. Especially QHY-treated rats showed highest RA of Firmicutes (90.7%) and the amelioration of CAG using QHY attributed by beneficial bacterial enrichment, especially Ruminococcus, Lactobacillus and Bifidobacterium. In addition, alpha and beta diversity analysis also demonstrated the clear dispersion and aggregation that revealed the alteration and steady of bacterial community structures. In summary, QHY has potential application value in the treatment of CAG, which attributed to close relation with the modulatory of internal bacterial communities.

Multivariate statistical and comparison analysis of chemical constituents in Arenaria kansuensis Maxim. from different regions in Qinghai-Tibet Plateau.

INTRODUCTION: Arenaria kansuensis Maxim. (AKM) is one of the most valued medicinal and edible herbs widely used in Qinghai-Tibet Plateau and there is also a large number of AKM bioactive constituents for health benefits of human beings. However, few works have referred to phytochemical content, fingerprint analysis and quality control of AKM. Therefore, the establishment of validated analytical methods is urgently needed for fingerprint comparison and quantitative analysis of AKM multicomponent. OBJECTIVES: To determine quantitatively and compare the phytochemical constituents of AKM located at different areas. METHODOLOGY: The chemical constituents in AKM samples were separated, identified, and quantified by high-performance liquid chromatography (HPLC) with a diode array detector. The discrimination and separation models for the chemical constituents were developed by chemometric analysis. RESULTS: The flavones and ß-carboline alkaloids were rich in AKM herbs, and the overall pattern of phytochemical profiles was the same, while the significant differences were detected in the total flavonoids, total ß-carboline alkaloids and individual contents, especially the predominant compounds such as tricin and arenarine B. This demonstrated that ecogeographical origin gave an important impact on phytochemical compositions which could be considered as reliable parameters for classifying the AKM resources. Moreover, the contents of AKM constituents were higher in July and/or August than other months of the year, and there were no significant differences in the main phytochemical contents between cultivated and wild AKM herbs. CONCLUSION: This study could provide credible data and method for geographical origin trace, comprehensive evaluation and further utilization of AKM resources.

PET evaluation of light-induced modulation of microglial activation and GLP-1R expression in depressive rats.

Light therapy has been accepted as a promising therapeutic choice for depression. Positron emission tomography (PET) combined with specific radiotracers has great benefits for revealing pathogenesis and developing therapeutics. This study aimed to investigate the influences of light therapy on microglial activation and glucagon-like peptide-1 receptor (GLP-1R) expression in the brain of depressive rats using [18F]DPA-714 and [18F]exendin-4 PET. The results showed that chronic unpredictable mild stress (CUMS)-induced depressive rats had poorer performance in behavioral tests compared to normal rats (p < 0.05) and the depressive-like behavior could be ameliorated by light therapy. Besides, depressive rats had significantly higher [18F]DPA-714 uptake and lower [18F]FDG uptake compare to normal rats in 11 and 9 regions of interest (ROIs) of the brain, respectively (p < 0.05). After 5 weeks of light therapy, higher [18F]FDG and [18F]exendin-4 uptake was observed in most ROIs of light therapy-treated depressive rats compared to untreated depressive rats (p < 0.05) and no significant differences existed in [18F]DPA-714 uptake between the two groups. This study demonstrated that light therapy can ameliorate depressive-like behavior, improve glucose metabolism, and halt the decline of brain GLP-1R expression of depressive rats, but have no effects on microglial activation caused by CUMS. Besides, this study validated that [18F]DPA-714 and [18F]exendin-4 PET have the potential for noninvasive evaluation of microglial activation and GLP-1R expression in the brain of depression.

Flavonoid compounds isolated from Tibetan herbs, binding to GABAA receptor with anxiolytic property.

ETHNOPHARMACOLOGICAL RELEVANCE: Previously, the phytochemical constituents of Biebersteinia heterostemon Maxim (BHM) and Arenaria kansuensis Maxim (AKM) were studied and the evaluation of anxiolytic effect based on their extracts was also investigated. The two traditional Tibetan herbs, BHM and AKM, have been widely used in Qinghai-Tibet Plateau for cardiopulmonary disorders and neuropsychiatric diseases. The anxiolytic activities of a number of agents mediated by α2/3-containing GABAA receptors (GABAARs) have been demonstrated through the genetic and pharmacological studies. Flavonoids, such as flavones and flavanols, are a class of ligands that act at GABAARs and exhibit anxiolytic effects in vivo. Here, the flavonoids are the predominant constituents isolated from BHM and AKM. And our purpose is to investigate structure-activity relationships of the flavonoid compounds with binding to BZ-S of GABAAR complexes, and to search for anxiolytic constituents that lack undesirable-effects such as sedation and myorelaxation. MATERIALS AND METHODS: The flavonoid constituents were separated and purified through the repeatedly silica gel or/and C18 column chromatography. The affinities of the compounds for BZ-S of GABAARs were detected by the radioreceptor binding assay with bovine cerebellum membranes, in which the different recombinant subunits-containing GABAARs were expressed in HEK 293T cells. The behavior tests, including elevated plus maze, locomotor activity, holeboard, rotarod and horizontal wire, were used to determine and evaluate the anxiolytic, sedative, and myorelaxant effects of these flavonoids. RESULTS: Eleven total flavonoid compounds were obtained from the Tibetan herbs (BHM and AKM). The flavones with 6-and/or 8-OMe possessed the most potent binding affinity to GABAARs, which were based on the result of structure-activity relationships analysis. Demethoxysudachitin (DMS, Ki = 0.59 µM), a flavone that binds to recombinant α1-3/5 subunit-containing GABAARs, was isolated from BHM, and exhibited high anxiolytic activity, without inducing sedation and myorelaxation. Moreover, the anxiolytic effect of DMS was antagonized by flumazenil, suggesting that a mode of action was mediated via the BZ-S of GABAARs. CONCLUSIONS: This present study indicated that the flavones, especially DMS, are novel GABAAR ligands and therapeutic potential candidates for anxiety.

BACKGROUND: Diabetic nephropathy is a frequent microvascular complication of diabetes mellitus that causes end-stage renal disease most of the time. In China, Shenkang injection is one of widely used traditional Chinese medicine for treating chronic kidney disease, but its efficacy and safety have not yet been clarified. We will systematically review the current randomized controlled trial (RCT) evidence to summarize the efficacy and safety of Shenkang injection in treating diabetic nephropathy. METHODS: We will search 7 literature databases including PubMed, EMBASE, Cochrane Library, Sinomed, Chinese National Knowledge Infrastructure, Wanfang, and VIP. Two trial registry platforms will also be searched. The time frame of the search will be from the inceptions of the databases to December 31, 2020. RCTs assessing Shenkang injection combined with basic treatments versus basic treatments alone for treating diabetic nephropathy will be included. The risk of bias within the individual RCTs will be evaluated using criteria proposed by the Cochrane Handbook 5.1.0. The primary outcomes to be investigated are glomerular filtration rate and serum creatinine; the secondary outcome will include 24-hour urine albumin excretion rate, blood urea nitrogen, fasting blood glucose, postprandial blood glucose, hemoglobin A1c, total cholesterol, triglyceride, response to treatment, and incidence of adverse events. The effect data of individual RCTs by performing random-effects model meta-analysis. Statistical heterogeneity will be measured by the Cochran Q test and I-squared statistics. Three subgroup analyses, set based on clinical experience, will be performed to explore the sources of heterogeneity. Sensitivity analyses excluding RCTs with high risk of bias and using fixed effect model will be done to test the robustness of the meta-analytic results. Publication bias across included RCTs will be evaluated by funnel plots and Egger test. RESULTS: This study will provide systematic review on the efficacy and safety of Shenkang Injection as adjuvant therapy in patients with diabetic nephropathy by rigorous quality assessment and reasonable data synthesis. The results will be submitted to a peer-reviewed journal for publication. CONCLUSION: This systematic review will provide the best evidence currently on Shenkang Injection as adjuvant therapy in patients with diabetic nephropathy.

First Report of Damping-Off Caused by Mucor circinelloides on Aconitum carmichaelii in China.

Aconitum carmichaelii is a typical traditional Chinese medicinal herb that has been grown for more than one thousand years in China (Singhuber et al. 2009). Surveys for damping-off of A. carmichaelii were conducted from 2016 to 2018 in three of China's major planting areas (Shaanxi, Sichuan, and Yunnan Province). Damping-off was observed from April to June with disease incidences ranging from 5% to 11% in ten investigated fields. In the early stage of disease development, the roots were fully covered by white mycelia. When the disease was severe, seedlings were stunted, turned yellow, had withered roots, and some eventually died. One fungus was consistently isolated from the diseased roots in the planting areas of Shaanxi Province (33°7'42″N and 107°20'27″E) on PDA medium. It was identified as Mucor circinelloides, based on morphological characteristics (Schipper 1976). Three isolates from different regions were characterized by yellowish colonies composed of tall and short sporangiophores 6-11 µm in width, terminal and globose sporangia, ellipsoidal sporangiospores 5-8 µm in length and 4-5 µm in width, and obovoid columellae. The internal transcribed spacer regions (ITS) and the large subunit (28S) of ribosomal RNA gene from the representative isolate, MC180610 (GenBank accession no. MK087755, MT043749), were also amplified and sequenced using the universal primer sets, ITS1/ITS4 and NL1/NL4, respectively. BLAST analyses of the ITS sequence showed 99.38% identity with the type strain (CBS 195.68) of M. circinelloides (GenBank accession no. NR_126116), and the 28S sequence showed 99.44% identity with the strain (CBS 274.49) of M. circinelloides f. circinelloides (GenBank accession no. MH868051). The pathogenicity of M. circinelloides isolate (MC180610) to A. carmichaelii was examined by inoculating 150 ml of the hypha suspension of M. circinelloides prepared from a 10-day-old potato dextrose broth culture into the soils of healthy potted A. carmichaelii plants. Uninoculated potted A. carmichaelii plants served as controls. There were three replicates for the inoculated and control plants. All the potted A. carmichaelii plants were incubated at 25°C under 12 h light 12 h dark conditions. The symptoms that developed on M. circinelloides inoculated A. carmichaelii plants were similar to those observed in the field; control plants did not show symptoms. The pathogen was reisolated from symptomatic roots onto the PDA medium and morphologically identified as M. circinelloides. M. circinelloides has been reported as a pathogen of papaya (Carica papaya), Mandarin fruits (Citrus reticulata), and sweet potatoes (Ipomea batatas), respectively (Cruz-Lachica et al. 2018; Saito et al. 2016; Oladoye et al. 2016), but it has never been reported on A. carmichaelii before. This is the first report of damping-off caused by M. circinelloides on A. carmichaelii. This pathogen may present a threat to the production of A. carmichaelii in China.

The Assessment of Diet Contaminated with Aflatoxin B1 in Juvenile Turbot (Scophthalmus maximus) and the Evaluation of the Efficacy of Mitigation of a Yeast Cell Wall Extract.

This study aimed to investigate the effects of dietary AFB1 on growth performance, health, intestinal microbiota communities and AFB1 tissue residues of turbot and evaluate the mitigation efficacy of yeast cell wall extract, Mycosorb® (YCWE) toward AFB1 contaminated dietary treatments. Nine experimental diets were formulated: Diet 1 (control): AFB1 free; Diets 2-5 or Diets 6-9: 20 µg AFB1/kg diet or 500 µg AFB1/kg diet + 0%, 0.1%, 0.2%, or 0.4% YCWE, respectively). The results showed that Diet 6 significantly decreased the concentrations of TP, GLB, C3, C4, T-CHO, TG but increased the activities of AST, ALT in serum, decreased the expressions of CAT, SOD, GPx, CYP1A but increased the expressions of CYP3A, GST-ζ1, p53 in liver. Diet 6 increased the AFB1 residues in serum and muscle, altered the intestinal microbiota composition, decreased the bacterial community diversity and the abundance of some potential probiotics. However, Diet 8 and Diet 9 restored the immune response, relieved adverse effects in liver, lowered the AFB1 residues in turbot tissues, promoted intestinal microbiota diversity and lowered the abundance of potentially pathogens. In conclusion, YCWE supplementation decreased the health effects of AFB1 on turbot, restoring biomarkers closer to the mycotoxin-free control diet.

Mannan oligosaccharide increases the growth performance, immunity and resistance capability against Vibro Parahemolyticus in juvenile abalone Haliotis discus hannai Ino.

This trial was conducted to investigate the effect of mannose oligosaccharides (MOS) on the growth performance, antioxidation, immunity and disease resistance of Vibro Parahemolyticus in juvenile abalone Haliotis discus hannai Ino. Four formulated diets were produced to contain 0.00 g/kg, 0.40 g/kg, 0.80 g/kg and 1.60 g/kg Actigen®, with functional ingredients of MOS, respectively. Accordingly, the experimental diets were named as A0, A4, A8 and A16. After 120-days feeding trial, the best growth performance was observed in A8 group (P < 0.05) and there was no significant difference in A0, A4 and A16 groups. With the increase of dietary MOS, the activity of the total antioxidant capacity in hepatopancreas is increasingly elevated (P < 0.05) while no significant difference was observed on activity of glutathione S-transferase (P > 0.05). The activities of superoxide dismutase and glutathione peroxidase were firstly increased and then decreased, with the highest values in A8 group (P < 0.05). Immune-related parameters were significantly affected by dietary MOS inclusion. Specifically, the activities of alkaline phosphatase and acid phosphatase in hepatopancreas and serum of abalone fed diets containing MOS were significantly higher than those of control A0 group (P < 0.05). Moreover, the highest values of both enzymes were observed in hepatopancreas of A8 group but in serum of A16 group, respectively. The lysozyme activities in hepatopancreas and serum of A4 group were significantly higher than those of other groups (P < 0.05) and there was no significant difference in A0, A8 and A16 groups (P > 0.05). The activities of cytophagy and respiratory burst in serum of abalone were not significantly affected by dietary MOS content (P > 0.05). The mRNA levels of focal adhesion kinase and integrin-linked kinase were gradually elevated with the increase of dietary MOS, with the highest value recorded in A16 group (P < 0.05). The gene expression of caspse-3 in A8 group was dramatically higher than those of other groups (P < 0.05) and there was no significant difference in A0, A4 and A16 groups (P > 0.05). The mRNA level of nuclear factor-κB was not significantly affected by dietary MOS (P > 0.05). During 56 h of V. Parahemolyticus challenge period, the accumulated mortality rate of abalone fed diets containing MOS were significantly lower than that of control A0 group in each time point (P < 0.05). Overall, the lowest rate was happened in A8 group (P < 0.05). In conclusion, MOS inclusion in diet has obviously positive effect on growth, immunity and disease resistance capability of abalone, with the optimal level of Actigen® at 0.80 g/kg in diet.

It is expected that this review will provide useful information for anyone who is interested in OR.

HPLC Profile of Longan (cv. Shixia) Pericarp-Sourced Phenolics and Their Antioxidant and Cytotoxic Effects.

Longan (Dimocarpus longan Lour.) pericarp, the main by-product of aril and pulp processing, is abundant in phenolic compounds and worthy of further utilization. The present work firstly reported HPLC analysis and in vitro antioxidant evaluation of longan (cv. Shixia) pericarp-derived phenolics (LPPs), the purified longan pericarp extract (LPE), as well as their cytotoxic effect on lung cancer cell line, A549. The results indicated that the purified LPE had significant amounts of phenolics, with content of 57.8 ± 0.6 mg of gallic acid equivalents per gram of dry longan pericarp (mg GAE·g-1 DLP), which consisted of six phenolic compounds (A⁻F), including protocatechuic acid (A), isoscopoletin (B), quercetin (C), ellagic acid (D), corilagin (E), and proanthocyanidins C1 (F). Antioxidant assays showed that LPPs (10 µM) and LPE (1.0 mg·mL-1) had certain antioxidant activities, in which corilagin (E) possessed the best DPPH radical scavenging rate 71.8 ± 0.5% and •OH inhibition rate 75.9 ± 0.3%, and protocatechuic acid (A) exhibited the strongest Fe2+ chelating ability 36.4 ± 0.7%. In vitro cytotoxic tests suggested that LPPs had different effect on A549 cell line, in which corilagin (E) exhibited potent cytotoxicity with an IC50 value of 28.8 ± 1.2 µM. These findings were further confirmed by cell staining experiments.

Responses of antioxidant defenses in the clam Mactra veneriformis to 2,2',4,4'­tetrabromodiphenyl ether exposure.

Antioxidant enzymes play essential roles against oxidative stress caused by 2,2',4,4'-tetrabromodiphenyl ether (BDE-47), which is ubiquitous in marine environment and organisms. However, research on antioxidant responses to BDE-47 in marine bivalves is scarce. In this study, we identified the full-length cDNA of catalase (CAT), and glutathione peroxidase (GPx) in the clam Mactra veneriformis. Subsequently, the responses of CAT, GPx, and copper, zinc-superoxide dismutase (Cu, Zn-SOD) were investigated in the clams exposed to 0.1, 1, and 10 µg/L BDE-47 for 7 days, and then depurated in natural seawater for 3 days. MvCAT and MvGPx contained conserved sequences. The deduced amino acid sequences shared high similarity with CATs and GPxs in other mollusks. M. veneriformis accumulated BDE-47 in a dose-dependent manner and eliminated BDE-47 poorly. BDE-47 induced a time- and dose-dependent increase of malondialdehyde content. Both the dose and the duration had significant effect on mRNA expressions and activities of the three antioxidants. Cu, Zn-SOD responded to BDE-47 earlier than CAT and GPx. The antioxidant responses could recover after depuration. These results suggested that M. veneriformis could accumulate BDE-47 efficiently. Antioxidant enzymes were triggered to counter the oxidative stress generated by BDE-47. Cu, Zn-SOD acted as the first defense against oxidative stress, while CAT and GPx intervened later. This study is therefore helpful in understanding the antioxidant responses to PBDEs in marine bivalves.

[Analysis of Regularity of Acupoint Selection in Acupuncture Treatment of Urticaria Based on Data Mining Technology].

OBJECTIVE: To analyze the regularity of acupoint selection, main acupoints and theoretical basis in acupuncture treatment of urticaria. METHODS: Papers collected from the time of establishment of each database to September of 2017 were retrieved from databases CNKI, CBM, VIP and WF by using keywords of "acupuncture" "moxibustion" "blood-letting therapy" "autohemotherapy" "cupping" "acupoint catgut embedding" "auricular points" "acupoint injection" "fire-needle" (or red-hot needle), "dermal needle" "needle-embedding" "urticaria" in both Chinese and English. The collected papers were brought into analysis according to the inclusion and exclusion criteria, from which the prescriptions for acupuncture treatment of urticaria were subjected into descriptive statistical analysis, association rule analysis, and cluster analysis by using Access 2010, Clementine 18.0 and Stata software. RESULTS: Outcomes of analysis indicated that the treatment methods of urticaria with acupuncture and moxibustion, with different emphases, may be classified into eight categories. For treating the exterior syndrome of urticaria, acupoints of the Bladder Meridian, Governor Vessel and Conception Vessel were often employed to harmonize Ying and Wei and to dispel the pathogenic wind, while for treating the interior syndrome, acupoints of the Large Intestine Meridian, Spleen Meridian, and Stomach Meridian were usually used to invigorate the spleen to dispel dampness and to regulate blood circulation. The top five frequently used acupoints were Quchi (LI 11), Xuehai (SP 10), Zusanli (ST 36), Sanyinjiao (SP 6) and Geshu (BL 17). It was crucial to make use of the specific acupoints with adequate meridian-qi, such as He-Sea points, Back-Shu points, and Yuan-Primary points. There were some fixed forms in the combination of acupoints, including LI 11, SP 10, Dazhui (GV 14) and auricular Lung, Shenmen, Fengxi, Adrenal gland, which had the highest confidence coefficient for the meridian points and ear acu-points, respectively. The outcomes of cluster analysis about the acupoint prescriptions showed that 12 acupoint groups as the SP 6-Hegu (LI 4)-LI 11-SP 10-ST 36, etc. were frequently used. CONCLUSION: The regularity of acupuncture treatment of urticaria can be discovered using data mining technology, resulting in an in-depth understanding and having a solid theoretical basis.

Novel role of resveratrol: suppression of high-mobility group protein box 1 nucleocytoplasmic translocation by the upregulation of sirtuin 1 in sepsis-induced liver injury.

BACKGROUND: High-mobility group protein box 1 (HMGB1) is essential in the response to injury during sepsis. We hypothesized that resveratrol (RESV) administration would inhibit nuclear-cytoplasmic HMGB1 translocation in hepatocytes, which is associated with sirtuin 1 (SIRT1) upregulation. We investigated the regulatory role of SIRT1 in HMGB1 nucleocytoplasmic translocation and its effect on sepsis-induced liver injury. METHODS: Rats were randomly assigned to pretreatment with RESV (60 mg/kg per day), nicotinamide (60 mg/kg per day), or vehicle (olive oil), which was administered by gavage for 3 days directly before cecal ligation and puncture was performed to induce sepsis. Parallel control groups were established. Rats were killed 24 h after surgery, and cytokine production, histology, apoptosis, SIRT1, serum HMGB1, nuclear and cytoplasmic HMGB1/ac-HMGB1, and the interaction between SIRT1 and HMGB1 were evaluated. In vitro evaluations were performed in human liver L02 cells subjected to lipopolysaccharide-induced injury, and siRNA-mediated SIRT1 knockdown experiments were performed. RESULTS: Sepsis-induced serum aminotransferase activities and proinflammatory chemokine levels were reduced by RESV pretreatment, which also improved liver histological parameters in association with SIRT1 upregulation. Resveratrol inhibited HMGB1 cytoplasmic translocation. Nicotinamide, an SIRT1 inhibitor, reduced the SIRT1-mediated suppression of HMGB1 translocation and aggravated cecal ligation and puncture-induced liver damage. Sirtuin 1 knockdown in vitro confirmed that RESV increased the SIRT1-mediated repression of HMGB1 translocation. In vivo, SIRT1 and HMGB1 physically interacted in the nucleus, and SIRT1 regulated HMGB1 acetylation in response to septic liver injury. CONCLUSIONS: Resveratrol protects against sepsis-induced liver injury through the SIRT1-mediated HMGB1 nucleocytoplasmic translocation pathway, a new potential therapeutic target in sepsis-induced liver injury.
