Simultaneous inorganic nitrogen and phosphate removal by aerobic-heterotrophic fungus Fusarium keratoplasticum FSP1: Performance, pathway and application.

Fungi with multiple contaminant removal function have rarely been studied. Here, a novel fungal strain Fusarium keratoplasticum FSP1, which was isolated from halophilic granular sludge, is reported for first time to perform simultaneous nitrogen and phosphate removal. The strain showed wide adaptability under C/N ratios of 30-35, salinities of 0 %-3 % (m/v), and pH of 7.5-9.5. The maximum removal rates of ammonium, nitrate and nitrite were 4.43, 4.01 and 2.97 mg N/L/h. The nitrogen balance, enzyme activity and substrate conversion experiments demonstrated a single strain FSP1 can assimilate inorganic nitrogen and convert inorganic nitrogen to gaseous nitrogen through heterotrophic nitrification or aerobic denitrification. About 39 %-42 % of the degraded phosphorus was in the extracellular polymeric substances (EPS). Orthophosphate was the main phosphorus species in the cell, whereas phosphate monoester and diester were in the EPS. The novel strain FSP1 is a potential candidate for wastewater treatment.

Identification of ARF transcription factor gene family and its defense responses to bacterial infection and salicylic acid treatment in sugarcane.

Auxin response factor (ARF) is a critical regulator in the auxin signaling pathway, involved in a variety of plant biological processes. Here, gene members of 24 SpapARFs and 39 SpnpARFs were identified in two genomes of Saccharum spontaneum clones AP85-441 and Np-X, respectively. Phylogenetic analysis showed that all ARF genes were clustered into four clades, which is identical to those ARF genes in maize (Zea mays) and sorghum (Sorghum bicolor). The gene structure and domain composition of this ARF family are conserved to a large degree across plant species. The SpapARF and SpnpARF genes were unevenly distributed on chromosomes 1-8 and 1-10 in the two genomes of AP85-441 and Np-X, respectively. Segmental duplication events may also contribute to this gene family expansion in S. spontaneum. The post-transcriptional regulation of ARF genes likely involves sugarcane against various stressors through a miRNA-medicated pathway. Expression levels of six representative ShARF genes were analyzed by qRT-PCR assays on two sugarcane cultivars [LCP85-384 (resistant to leaf scald) and ROC20 (susceptible to leaf scald)] triggered by Acidovorax avenae subsp. avenae (Aaa) and Xanthomonas albilineans (Xa) infections and salicylic acid (SA) treatment. ShARF04 functioned as a positive regulator under Xa and Aaa stress, whereas it was a negative regulator under SA treatment. ShARF07/17 genes played positive roles against both pathogenic bacteria and SA stresses. Additionally, ShARF22 was negatively modulated by Xa and Aaa stimuli in both cultivars, particularly LCP85-384. These findings imply that sugarcane ARFs exhibit functional redundancy and divergence against stressful conditions. This work lays the foundation for further research on ARF gene functions in sugarcane against diverse environmental stressors.

Synergistic action of indole-3-carbinol with membrane-active agents against multidrug-resistant Gram-negative bacteria.

The purpose of this study was to evaluate the antimicrobial activity of indole-3-carbinol (I3C) with membrane-active agents, namely carbonyl cyanide 3-chlorophenylhydrazone (CCCP) and ethylenediaminetetraacetic acid (EDTA) against multidrug-resistant (MDR) Gram-negative bacteria and bacterial persisters. The determination of minimal inhibitory concentration (MIC) showed that I3C was effective against Acinetobacter baumannii (3.13‒6.25 × 10-3 mol l-1), Klebsiella pneumoniae (8 × 10-3 mol l-1), Pseudomonas aeruginosa (6.25‒12.5 × 10-3 mol l-1), and Escherichia coli (6.25‒12.5 × 10-3 mol l-1). Our study demonstrated that EDTA synergistically enhanced the bactericidal activity of I3C against most MDR Gram-negative bacteria isolates and contributed to an 8- to 64-fold MIC reduction compared with that of I3C alone, yet CCCP only displayed synergy with I3C against P. aeruginosa and A. baumannii. The EDTA-I3C combination also significantly reduced the viable number of testing bacteria (P = 7.2E-05), effectively reduced bacterial persisters, and repressed bacterial growth compared with that the use of I3C alone. Our data demonstrate that use of EDTA as adjuvant molecules can effectively improve the antibacterial activity of I3C and may help to reduce the development of antimicrobial resistance.

[Intervention effect of Chuanxiong-Chishao herb pair on circRNA/lncRNA expression profile in a myocardial infarction-atherosclerosis model].

This study aimed to explore the intervention effect of Chuanxiong-Chishao herb pair(CX-CS) on a myocardial infarction-atherosclerosis(MI-AS) mouse model and investigate its effect on the expression profile of circular RNAs(circRNAs)/long non-coding RNAs(lncRNAs) in ischemic myocardium and aorta. Sixty male ApoE~(-/-) mice were randomly assigned to a model group, high-, medium-, and low-dose CX-CS groups(7.8, 3.9, and 1.95 g·kg~(-1)), and a positive drug group(metoprolol 26 mg·kg~(-1) and simvastatin 5.2 mg·kg~(-1)), with 12 mice in each group. Male C57BL/6J mice were assigned to the sham group. The mice in the model group and the groups with drug intervention were fed on a high-fat diet for 10 weeks, followed by anterior descending coronary artery ligation. After that, the mice were fed on a high-fat diet for another two weeks to induce the MI-AS model. The mice in the sham group received normal feed, followed by sham surgery without coronary artery ligation. Mice in the groups with drug intervention received CX-CS or positive drug by gavage for four weeks from the 9th week of high-fat feeding, and those in the model group and the sham group received an equal volume of normal saline. Whole transcriptome sequencing was performed on the heart and aorta tissues of the medium-dose CX-CS group, the model group, and the sham group after administration. The results showed that the medium-and high-dose CX-CS groups showed improved cardiac function and reduced myocardial fibrosis area, and the medium-dose CX-CS group showed significantly reduced plaque area. CX-CS treatment could reverse the expression of circRNA＿07227 and circRNA＿11464 in the aorta of AS model and circRNA expression(such as circRNA＿11505) in the heart of the MI model. Differentially expressed circRNAs between the CX-CS-treated mice and the model mice were mainly enriched in lipid synthesis, lipid metabolism, lipid transport, inflammation, and angiogenesis in the aorta, and in angiogenesis, blood pressure regulation, and other processes in the heart. CX-CS treatment could reverse the expression of lncRNAs such as ENSMUST00000162209 in the aorta of the AS model and TCONS＿00002123 in the heart of the MI model. Differentially expressed lncRNAs between the CX-CS-treated mice and model mice were mainly enriched in lipid metabolism, angiogenesis, autophagy, apoptosis, and iron death in the aorta, and in angiogenesis, autophagy, and iron death in the heart. In summary, CX-CS can regulate the expression of a variety of circRNAs and lncRNAs, and its intervention mechanism in coronary heart disease may be related to the regulation of angiogenesis and inflammation in ischemic myocardium, as well as lipid metabolism, lipid transport, inflammation, angiogenesis in AS aorta.

Tongue acupuncture for the treatment of post-stroke dysphagia: a meta-analysis of randomized controlled trials.

Objectives: Post-stroke dysphagia is the most common neurological impairment after stroke. The swallowing process is controlled by a network made up of the cerebral cortex, subcortical area, and brainstem structure. The disruption of the swallowing network after stroke leads to dysphagia. The affected swallowing muscles after stroke mainly include the laryngeal muscles (suprahyoid muscle and thyrohyoid muscle) and infrahyoid muscle. These muscles experience kinematic effects and muscle strength weakens, resulting in reduced movement in the swallowing process. Acupuncture can change the excitability of cerebral cortical nerve cells, promote the recovery of neurological function, and enhance neuromuscular excitability, ultimately improving the control of swallowing-related nerves and muscles and promoting swallowing functional recovery. In this meta-analysis, we systematically evaluate the clinical efficacy of acupuncture in the treatment of post-stroke dysphagia. Methods: Randomized controlled trials of tongue acupuncture therapy for post-stroke dysphagia were searched and selected from seven electronic databases (PubMed, CBM, Cochrane, Embase, CNKI, VPCS, and Wan fang). The Cochrane Collaboration tool was used to conduct methodological quality assessment. Rev. Man 5.4 software was utilized to perform data analysis. Results: A total of 15 studies with 1,094 patients were included. Meta-analysis Showed that WST score WST score (MD = -0.56, 95% CI (-1.23, 0.12), Z = 1.62, p < 0.00001), SSA score (MD = -1.65, 95% CI (-2.02, -1.28), Z = 8.77, p < 0.00001). These results suggested that the treatment group (tongue acupuncture or tongue acupuncture combined with other therapies) was superior to the control group in reducing WST scores and SSA scores. The clinical efficacy of the tongue acupuncture group was better compared with the control group (MD = 3.83, 95% CI (2.61, 5.62), Z = 6.88, p < 0.00001). Conclusion: The meta-analysis showed that the total effective rate of patients with dysphagia after stroke in the treatment group (acupuncture, tongue acupuncture, and acupuncture combined with other therapy) was higher than that in the control group. These results indicated that acupuncture, tongue acupuncture, and acupuncture combined with other therapy can improve post-stroke dysphagia.

Soft drinks, tea and coffee consumption in relation to risk of fracture: evidence from china health and nutrition survey.

INTRODUCTION: To investigate the association between soft drinks, tea and coffee consumption, and risk of fracture in the China Health and Nutrition Survey. MATERIALS AND METHODS: A cross-sectional study with multi-stage random cluster sampling was conducted in nine Chinese provinces in 2004, 2006, 2009 and 2011. A total of 36,740 participants were included the data analyses. Self-administered questionnaires and physical examinations provided data on beverages consumption, fracture history, and other potential risk factors. Binary logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for potentially confounding variables. RESULTS: The prevalence of fracture increased over the 7-year period of the surveys, with 1833 (5.3%) participants reporting a fracture history. Soft drink consumption increased over this time period, and tea consumption was relatively stable, whereas coffee consumption tended to increase sharply. Consumers of soft drinks ≥ 3 times/week (versus never) had a higher risk of fracture (OR = 1.86, 95% CI = 1.43-2.32, p < 0.001, p for trend = 0.039). Consumers of tea ≥ 5 cups/day (versus never) also had a higher risk of fracture (OR = 1.21, 95% CI = 1.09-1.45, p = 0.028, p for trend < 0.001). Similarly, consumers of coffee ≥ 2 cups/day (versus never) had a higher risk of fracture (OR = 1.84, 95% CI = 1.01-3.34, p = 0.045, p for trend = 0.002). Subgroup analyses by gender suggested that coffee consumption increased risk of fracture in females (OR = 1.84, 95% CI = 1.32-2.63, p = 0.001). CONCLUSION: Our findings suggest that high consumption of soft drinks, tea and coffee is associated with an increased risk of fracture in the Chinese population. Which has important public health implications given the widespread consumption of these beverages.

Binding of Cd(II) to birnessite and fulvic acid organo-mineral composites and controls on Cd(II) availability.

Manganese oxide minerals (MnOs) are major controls on cadmium (Cd) mobility and fate in the environment. However, MnOs are commonly coated with natural organic matter (OM), and the role of this coating in the retention and availability of harmful metals remains unclear. Herein, organo-mineral composites were synthesized using birnessite (BS) and fulvic acid (FA), during coprecipitation with BS and adsorption to preformed BS with two organic carbon (OC) loadings. The performance and underlying mechanism of Cd(II) adsorption by resulting BS-FA composites were explored. Consequently, FA interactions with BS at environmentally representative (5 wt% OC) increase Cd(II) adsorption capacity by 15.05-37.39% (qm = 156.5-186.9 mg g-1), attributing to the enhanced dispersion of BS particles by coexisting FA led to significant increases in specific surface area (219.1-254.8 m2 g-1). Nevertheless, Cd(II) adsorption was notably inhibited at a high OC level (15 wt%). This might have derived from the supplementation of FA decreased pore diffusion rate and generated Mn(II/III) competition for vacancy sites. The dominant Cd(II) adsorption mechanism was precipitation with minerals (Cd(OH)2), and complexation with Mn-O groups and acid oxygen-containing functional groups of FA. In organic ligand extractions, the exchange Cd content decreased by 5.63-7.93% with low OC coating (5 wt%), but increased to 33.13-38.97% at a high OC level (15 wt%). These findings help better understand the environmental behavior of Cd under the interactions of OM and Mn minerals, and provide a theoretical basis for organo-mineral composite remediation of Cd-contaminated water and soil.

Dietary Inflammatory Index and Fractures in Midlife Women: Study of Women's Health Across the Nation.

CONTEXT: While evidence suggests that chronic, low-grade inflammation is a risk factor for bone loss and fractures, the potential relation between an inflammatory dietary profile and greater fracture risk is uncertain. OBJECTIVE: We examined whether a more inflammatory diet, consumed during pre- and early perimenopause, is associated with more incident fractures starting in the menopause transition (MT) and continuing into postmenopause. METHODS: Dietary inflammatory potential was quantified using 2 energy-adjusted dietary inflammatory index scores: one for diet only (E-DII), and one for diet plus supplements (E-DII-S). We included 1559 women from the Study of Women's Health Across the Nation, with E-DII and E-DII-S scores from the baseline visit (during pre- or early perimenopausal), and up to 20 years of follow-up. We excluded women using bone-beneficial medications at baseline; subsequent initiators were censored at first use. The associations of E-DII or E-DII-S (each tested as separate exposures) with incident fracture were examined using Cox proportional hazards regression. RESULTS: Adjusted for age, BMI, cigarette use, diabetes, MT stage, race/ethnicity, prior fracture, bone-detrimental medication use, aspirin or nonsteroidal anti-inflammatory drug use, and study site, greater E-DII and E-DII-S (tested separately) were associated with more future fractures. Each SD increment in E-DII and E-DII-S predicted 28% (P = .005) and 21% (P = .02) greater fracture hazard, respectively. Associations were essentially unchanged after controlling for bone mineral density. CONCLUSION: A more pro-inflammatory diet in pre- and early perimenopause is a risk factor for incident fracture. Future studies should consider whether reducing dietary inflammation in midlife diminishes fracture risk.

Artemisinin suppressed tumour growth and induced vascular normalisation in oral squamous cell carcinoma via inhibition of macrophage migration inhibitory factor.

BACKGROUND: Tumour vascular normalisation therapy advocates a balance between pro-angiogenic factors and anti-angiogenic factors in tumours. Artemisinin (ART), which is derived from traditional Chinese medicine, has been shown to inhibit tumour growth; however, the relationship between ART and tumour vascular normalisation in oral squamous cell carcinoma (OSCC) has not been previously reported. METHODS: Different concentrations(0 mg/kg, 25 mg/kg, 50 mg/kg, 100 mg/kg)of ART were used to treat the xenograft nude mice model of OSCC. The effects of ART on migration and proliferation of OSCC and human umbilical vein endothelial cells (HUVEC) cells were detected by scratch assay and CCK-8 assay. OSCC cells with macrophage migration inhibitory factor (MIF) silenced were constructed to explore the effect of MIF. RESULTS: Treatment with ART inhibited the growth and angiogenesis of OSCC xenografts in nude mice and downregulated vascular endothelial growth factor (VEGF), IL-8, and MIF expression levels. ART reduced the proliferation, migration, and tube formation of HUVEC, as well as the expression of VEGFR1 and VEGFR2. When the dose of ART was 50 mg/kg, vascular normalisation of OSCC xenografts was induced. Moreover, VEGF and IL-8 were needed in rhMIF restoring tumour growth and inhibit vascular normalisation after the addition of rhMIF to ART-treated cells. CONCLUSION: Artemisinin might induce vascular normalisation and inhibit tumour growth in OSCC through the MIF-signalling pathway.

Prediabetes and insulin resistance are associated with lower trabecular bone score (TBS): cross-sectional results from the Study of Women's Health Across the Nation TBS Study.

In pre- and early perimenopausal women, prediabetes (with blood glucose ≥ 110 mg/dL) and greater insulin resistance are associated with worse trabecular bone quality (as assessed by trabecular bone score). PURPOSE: Diabetes mellitus (DM) is associated with lower trabecular bone score (TBS) and fracture; less certain is whether the precursor states of prediabetes and increased insulin resistance are also related to adverse bone outcomes. We examined, in women who do not have DM, the associations of glycemic status (prediabetes vs. normal) and insulin resistance with TBS. METHODS: This was a cross-sectional analysis of baseline data collected from 42- to 52-year-old, pre- and perimenopausal participants in the Study of Women's Health Across the Nation (SWAN) TBS Study. Women with prediabetes were categorized as having either high prediabetes if their fasting glucose was between 110 and 125 mg/dL or low prediabetes if their fasting glucose was between 100 and 109 mg/dL. Normoglycemia was defined as a fasting glucose below 100 mg/dL. RESULTS: In multivariable linear regression, adjusted for age, race/ethnicity, menopause transition stage, cigarette use, calcium and vitamin D supplementation, lumbar spine bone mineral density, and study site, women with high prediabetes had 0.21 (p < 0.0001) standard deviations (SD) lower TBS than those with normoglycemia. Low prediabetes was not associated with lower TBS. When HOMA-IR levels were ≥ 1.62, each doubling of HOMA-IR was associated with a 0.11 SD decrement in TBS (p = 0.0001). CONCLUSION: Similar to diabetics, high prediabetics have lower TBS than normoglycemic individuals. Women with greater insulin resistance have lower TBS even in the absence of DM. Future studies should examine the associations of high prediabetes and insulin resistance with incident fracture.

Extracts of Bauhinia Championii Alleviate Acute Neuronal Injury After Ischemic Reperfusion by Improving Endoplasmic Reticulum Stress-Mediated Neuronal Apoptosis.

OBJECTIVE: Cerebral ischemia/reperfusion (I/R) is a potential factor for lethal injury, and currently lacks effective remedies. Bauhinia championii extracts (BCEs) have been reported to exhibit anti-oxidative and anti-hypoxia properties. The current work aimed to study whether BCE could alleviate neuronal injury caused by I/R. METHODS: To investigate the protective effects of BCE, oxygen-glucose deprivation/reperfusion (OGD/R) was applied to the HT22 cell line in vitro and to a cerebral I/R mouse model in vivo. RESULTS: Under OGD/R, the survival of HT22 cells was significantly prolonged after treatment with BCE. In vivo, BCE significantly reduced the infarct area and decreased neuronal apoptosis caused by I/R. It was further found that OGD/R could trigger endoplasmic reticulum (ER) stress and induce ER stress-mediated neuronal apoptosis in vivo and in vitro, while BCE could effectively alleviate ER stress and neuronal apoptosis. CONCLUSION: These results suggested that BCE exhibits neuroprotective effects by reducing ER stress-mediated apoptosis after cerebral I/R injury. BCE may therefore be an effective therapeutic regimen against cerebral I/R damage.

Removal of nano-sized polystyrene plastic from aqueous solutions using untreated coffee grounds.

Nanoplastic (NP) pollution is an emerging global concern due to its adverse impact on aquatic ecosystems. Nevertheless, the removal of aqueous NPs from aquatic environments remains a significant challenge. This study aims to investigate whether polystyrene NP in aqueous solutions can be removed using coffee grounds. Due to the difficulty associated with directly measuring NP levels and monitoring the biosorption process, we used fluorescent-orange amine-modified polystyrene beads (fluo-NP, 100 nm) to evaluate the efficacy of the biosorption process. The factors including pH, coffee grounds concentration, initial fluo-NP concentration, and contact time were optimized on batch experiments. In addition, the isotherm and kinetic models were employed to clarify the adsorption behaviors and mechanisms. It was found that aqueous fluo-NP particles were effectively adsorbed onto the coffee grounds over a wide pH range (pH 2-12), with a coffee ground concentration of 25 g/L leading to the maximum adsorption efficiency (74%). The equilibrium adsorption capacity of the coffee grounds was 4 mg/g for a reaction time of 40 min. Coffee grounds demonstrated the highest removal efficiency when the initial fluo-NP concentration was 100-125 mg/L. The Dubinin-Radushkevich model and pseudo-second-order model described the adsorption isotherm and kinetics well, respectively, and the adsorption at high fluo-NP concentration range was favorable. Moreover, the results suggest that the mechanism lies in the electrostatic interactions and hydrogen bonding between surface functional groups of the coffee grounds and the fluo-NP particles. Given that there is an urgent need to remove NPs from aqueous systems, this study illustrates that it is possible to use coffee ground biowaste for this purpose.

Image dataset on the Chinese medicinal blossoms for classification through convolutional neural network.

Tree blossoms have been widely used on the prevention and treatment of a variety of diseases in traditional Chinese medicine for thousand years [1,2]. The growth of flowers is not only for their ornamental value, but also for nutritional, medicinal, cooking, cosmetic and aromatic properties. They are a rich source of many compounds, which play an important role in various metabolic processes of the human body [3]. Edible flowers can promote the global demand for more attractive and delicious food, and can improve the nutritional content of gourmet food [4]. Flowers are beneficial for anti-anxiety, anti-cancer, anti-inflammatory, antioxidant, diuretic and immune-modulator, etc. It is very important to identify edible flowers correctly, because only a few are edible [5]. The shapes or colors of different flowers may be very similar. Visual evaluation is one of the classification methods, but it is error-prone and time-consuming [6]. Flowers are divided into flowers from herbaceous plants (flower) and flower trees (blossom). Now there is a public herbaceous flower dataset [7], but lack of dataset for Chinese medicinal blossoms. This article presents and establishes the dataset for twelve most commonly and economically valuable blossoms used in traditional Chinese medicine. The dataset provide a collection of blossom images on traditional Chinese herbs help Chinese pharmacist to classify the categories of Chinese herbs. In addition, the dataset can serve as a resource for researchers who use different algorithms of machine learning or deep learning for image segmentation and image classification.

Overexpression of MAL2 Correlates with Immune Infiltration and Poor Prognosis in Breast Cancer.

BACKGROUND: Myelin and lymphocyte, T cell differentiation protein 2 (MAL2) is highly expressed in various cancers and associated with the development and prognosis of cancer. However, the relationship between MAL2 and breast cancer requires further investigation. This study aimed to explore the prognostic significance of MAL2 in breast cancer. METHODS: MAL2 expression was initially assessed using the Oncomine database and The Cancer Genome Atlas (TCGA) database and verified by quantitative real-time polymerase chain reaction (RT-qPCR). The chi-square test or Fisher's exact test was used to explore the association between clinical characteristics and MAL2 expression. The prognostic value of MAL2 in breast cancer was assessed by the Kaplan-Meier method and Cox regression analysis. Gene set enrichment analysis (GSEA) was performed to identify the biological pathways correlated with MAL2 expression in breast cancer. Besides, a single-sample GSEA (ssGSEA) was used to assess the relationship between the level of immune infiltration and MAL2 in breast cancer. RESULTS: Both bioinformatics and RT-qPCR results showed that MAL2 was expressed at high levels in breast cancer tissues compared with the adjacent tissues. The chi-square test or Fisher's exact test indicated that MAL2 expression was related to stage, M classification, and vital status. Kaplan-Meier curves implicated that high MAL2 expression was significantly associated with the poor prognosis. Cox regression models showed that high MAL2 expression could be an independent risk factor for breast cancer. GSEA showed that 14 signaling pathways were enriched in the high-MAL2-expression group. Besides, the MAL2 expression level negatively correlated with infiltrating levels of eosinophils and plasmacytoid dendritic cells in breast cancer. CONCLUSION: Overexpression of MAL2 correlates with poor prognosis and lower immune infiltrating levels of eosinophils and plasmacytoid dendritic cells in breast cancer and may become a biomarker for breast cancer prognosis.

[Network pharmacology study of Tibetan medicine Corydalis Herba against acute myocardial ischemia].

In this study, the compound search was completed through SciFinder and CNKI databases, and the drug-like properties were screened in FAFdrugs4 and SEA Search Server databases. In addition, based on the target sets related to acute myocardial ischemia(AMI) searched in disease target databases such as OMIM database, GeneCards database and DrugBank, a network diagram of chemical component-target-pathway-disease was established via Cytoscape to predict the potential active components of Corydalis Herba, a traditional Tibetan herbal medicine which derived from the aerial parts of Corydalis hendersonii and C. mucronifera against AMI. A protein-protein interaction(PPI) network was constructed through the STRING database and the core targets in the network were predicted. And the enrichment analyses of core targets were completed by DAVID database and R software. Furthermore, a molecular docking method was used to verify the binding of the components with core targets using softwares such as Autodock Vina. The present results showed that there were 60 compounds related to AMI in Corydalis Herba, involving 73 potential targets. The GO functional enrichment analysis obtained 282 biological processes(BP), 49 cell components(CC) and 78 molecular functions(MF). KEGG was enriched into 85 pathways, including alcoholism pathway, endocrine resistance pathway, calcium signaling pathway, cAMP signaling pathway, vascular endothelial growth factor signaling pathway and adrenergic signaling transduction pathway of myocardial cells. The results of network topology analysis showed that the key components of anti-AMI of Corydalis Herba might be tetrahydropalmatine, etrahydrocolumbamine, N-trans-feruloyloctopamine, N-cis-p-coumaroyloctopamine, N-trans-p-coumaroylnoradrenline and N-trans-p-coumaroyloctopamine, and their core targets might be CDH23, SCN4 B and NFASC. The results of molecular docking showed that the key components of Corydalis Herba had stable binding activity with the core targets. This study provides reference for further elucidation of the pharmacological effects of Corydalis Herba against AMI, subsequent clinical application, and development.

[Effect of auricular acupuncture on reduction of sertraline hydrochloride in patients with depression: a randomized controlled trial].

OBJECTIVE: To observe the effect of auricular acupuncture on reduction rate of sertraline hydrochloride, and to explore the long-term efficacy of auricular acupuncture in patients with depression. METHODS: Seventy-two patients with depression were randomly divided into an observation group (36 cases, 1 case dropped off) and a control group (36 cases, 2 cases dropped off). The patients in the control group were treated with conventional dosage reduction method, that is, the dosage of sertraline hydrochloride was reduced by 25% every week until the dosage was stopped completely on the premise of no aggravation of depressive symptoms. Based on the conventional dosage reduction method used in the control group, the patients in the observation group were treated with auricular acupuncture at Xin (CO15), Gan (CO12), Shenmen (TF4), Pizhixia (AT4) and Neifenmi (CO18), once every 3 days for 4 weeks. The reduction of dosage was observed before dosage reduction, after 1, 2, 3, 4 weeks of dosage reduction and follow-up 6 months after the end of treatment; the rate of dosage reduction was observed after 4 weeks of dosage reduction and during follow-up; the Hamilton depression scale (HAMD) was used to evaluate the depression severity before dosage reduction, after 4 weeks of dosage reduction and during follow-up; the incidence rate of withdrawal syndrome and clinical efficacy were compared between the two groups. RESULTS: The dosage of sertraline hydrochloride in the observation group was less than that in the control group after 2, 3, 4 weeks of dosage reduction and during follow-up (P<0.05). The dosage reduction rates were 80.6% and 82.2% after 4 weeks of dosage reduction and during follow-up in the observation group, which were higher than 65.8% and 62.2% in the control group (P<0.05). After 4 weeks of dosage reduction, the HAMD scores in the two groups were higher than those before dosage reduction (P<0.05), and the HAMD score in the observation group was lower than that in the control group (P<0.05). During follow-up, HAMD score in the observation group was lower than that in the control group and that after 4 weeks of dosage reduction (P<0.05), while HAMD score in the control group was higher than that before dosage reduction and that after 4 weeks of treatment (P<0.05). The incidence rate of withdrawal syndrome in the observation group was 11.4% (4/35), which was lower than 47.1% (16/34) in the control group (P<0.05). After 4 weeks of dosage reduction and during follow-up, the total effective rate was 97.1% (34/35) in the observation group, which was higher than 79.4% (27/34) in the control group (P<0.05). CONCLUSION: Auricular acupuncture could effectively reduce the dosage of sertraline hydrochloride, improve the dosage reduction rate, reduce the incidence of withdrawal syndrome and reduce the risk of long-term recurrence in patients with depression.

[Clinical observation of acupuncture combined with moxibustion on college students with depression].

OBJECTIVE: To observe the clinical efficacy of acupuncture combined with moxibustion with seed-sized moxa cone in the treatment of depression in college students, and explore its effect on serum 5-hydroxytryptamine (5-HT). METHODS: Sixty undergraduates with depression were divided into acupuncture-moxibustion group and medication group according to the random number table, with 30 patients in each group. The patients in acupuncture-moxibustion group received acupuncture and moxibustion with seed-sized moxa cone at acupoints on Shaoyang meridian according to the method of "rotating the pivot and regulating the qi", one time every other day. The patients in medication group received oral administration of fluoxetine hydrochloride capsule 20 mg once a day, and both groups were treated continuously for 8 weeks. The scores of Hamilton depression (HAMD-17) scale, self-rating depression scale (SDS) and serum 5-HT content before and after treatment were compared between the two groups. RESULTS: Compared with before treatment, the HAMD-17 and SDS scores of the acupuncture-moxibustion group began to decrease after 2 weeks of treatment (P<0.05); while the HAMD-17 and SDS scores of the the medication group began to decrease after 4 weeks of treatment (P<0.05). After 2, 4 and 8 weeks of treatment, the HAMD-17 and SDS scores of the acupuncture-moxibustion group decreased more significantly than the medication group (P<0.05). The 5-HT contents of the two groups were significantly higher than those before treatment (P<0.05)，and there was no significant difference in serum 5-HT content between the two groups (P>0.05). The adverse reaction score of the acupuncture-moxibustion group was lower than that of the medication group (P<0.05). The total effective rate of the acupuncture-moxibustion group was 92.86%（26/28）, better than the medication group 81.48% (22/27,P<0.05). CONCLUSION: Acupuncture combined with seed-sized moxa cone moxibustion is more effective than oral administration of fluoxetine hydrochloride in treating college students' depression, and acupuncture combined with moxibustion has a faster onset and fewer adverse reactions in the treatment of college students' depression.

[Effect of abdominal penetrating moxibustion on function of core muscle group in stroke patients based on surface electromyography].

OBJECTIVE: To observe the effect of abdominal penetrating moxibustion on strength and endurance of core muscle group in patients with stroke. METHODS: Sixty-two patients with stroke were randomly divided into an observation group (31 cases, 2 cases dropped off) and a control group (31 cases, 2 cases dropped off). The patients in the control group were treated with routine basic treatment, acupuncture treatment and rehabilitation training; based on the treatment of the control group, the patients in the observation group were treated with abdominal penetrating moxibustion, approximately 50 min each time, once a day. The treatments in the two groups were given 5 times a week for 4 weeks. The root mean square (RMS) and median frequency (MF) of bilateral transverse abdominis and multifidus of performing sitting-standing and making steps were measured by surface electromyography before and after treatment. The postural assessment scale for stroke (PASS), Berg balance scale (BBS) and lower-limb Fugl-Meyer motor assessment (FMA) scores were observed before treatment, 2 weeks into treatment and 4 weeks into treatment. RESULTS: Compared before treatment, when performing different postures, the RMS and MF of bilateral transversus abdominis and multifidus in the two groups were increased after treatment (P<0.01, P<0.05). The RMS of affected-side transversus abdominis and multifidus and the MF value of bilateral transverse abdominis and multifidus in the observation group were higher than those in the control group (P<0.05). Compared before treatment, the PASS, BBS and FMA scores were increased 4 weeks into treatment in the two groups (P<0.01), and those in the observation group were higher than the control group (P<0.01). CONCLUSION: The abdominal penetrating moxibustion could effectively improve the strength and endurance of core muscle group, improve the posture control, balance ability and lower-limb motor function in patients with stroke.

[Effect of total phenolic part of Rhus chinensis against myocardial ischemia in mice].

Rhus chinensis is an important resource plant. The aqueous extract of R. chinensis roots or stems was to produce Shuguantong Syrup, which is mainly used for the treatment of coronary heart disease and angina pectoris with definite curative effect. On this basis, the crude phenolic part of R. chinensis prepared by macroporous resin was evaluated for the cardio protective effect against myocardial ischemia in mice. The results showed that the phenolic part group with oral administration at the dosages of 190.8-381.6 mg·kg~(-1), compared with the model group, reduced the values of left ventricular end systolic diameter(LVEDs) and the left ventricular end diastolic diameter(LVEDd), and increased the cardiac ejection fraction(EF) and left ventricular fractional shortening(FS) rate, which could effectively improve cardiac function and exert its anti-myocardial ischemia effect, and reduce the rising levels of creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH) in serum. HE staining showed that the phenolic part group reduced the infiltration of myocardial inflammatory cells and alleviated the degree of myocardial fibrosis and collagen deposition. TUNEL staining showed that the blue-green fluorescence of the phenolic part group decreased successively, and the degree of myocardial cell apoptosis was reduced. Immunohistochemical staining suggested that it could reduce the number of positive cells for p53 protein expression and significantly improve myocardial cell damage. All above data suggested that the phenolic part group had an anti-mycardial ischemis effect. Related mechanism studies revealed that the crude phenolic part could regulate the expressions of the p53 gene(p53), Bcl-2-associated X protein(Bax), B lymphoma-2 gene(Bcl-2), and caspase-3 protein(caspase-3) in myocardial tissue, suggesting that it could reduce cardiac remodeling and myocardial ischemic damage, and improve cardiac function by inhibiting myocardial apoptosis.This research laid a foundation for the elucidation of the pharmacological ingredients R. chinensis.

Faster Lumbar Spine Bone Loss in Midlife Predicts Subsequent Fracture Independent of Starting Bone Mineral Density.

CONTEXT: Bone mineral density (BMD) decreases rapidly during menopause transition (MT), and continues to decline in postmenopause. OBJECTIVE: This work aims to examine whether faster BMD loss during the combined MT and early postmenopause is associated with incident fracture, independent of starting BMD, before the MT. METHODS: The Study of Women's Health Across the Nation, a longitudinal cohort study, included 451 women, initially premenopausal or early perimenopausal, and those transitioned to postmenopause. Main outcome measures included time to first fracture after early postmenopause. RESULTS: In Cox proportional hazards regression, adjusted for age, body mass index, race/ethnicity, study site, use of vitamin D and calcium supplements, and use of bone-detrimental or -beneficial medications, each SD decrement in lumbar spine (LS) BMD before MT was associated with a 78% increment in fracture hazard (P = .007). Each 1% per year faster decline in LS BMD was related to a 56% greater fracture hazard (P = .04). Rate of LS BMD decline predicted future fracture, independent of starting BMD. Women with a starting LS BMD below the sample median, and an LS BMD decline rate faster than the sample median had a 2.7-fold greater fracture hazard (P = .03). At the femoral neck, neither starting BMD nor rate of BMD decline was associated with fracture. CONCLUSION: At the LS, starting BMD before the MT and rate of decline during the combined MT and early postmenopause are independent risk factors for fracture. Women with a below-median starting LS BMD and a faster-than-median LS BMD decline have the greatest fracture risk.
