ABSTRACT

In order to enrich the transcriptome data of Fagopyrum dibotrys plants, analyze the genes encoding key enzyme involved in flavonoid biosynthesis pathway, and mine their functional genes, in this study, we performed RNA sequencing analysis for the rhizomes, roots, flowers, leaves and stems of F. dibotrys on the BGISEQ-500 sequencing platform. After de novo assembly of transcripts, a total of 205 619 unigenes were generated and 132 372 unigenes were obtained and annotated into seven public databases, of which, 81 327 unigenes were mapped to the GO database and most of the unigenes were annotated in cellular process, biological regulation, binding and catalytic activity. Besides, 86 922 unigenes were enriched in 136 pathways using KEGG database' and we identified 82 unigenes that encodes key enzymes involved in flavonoid biosynthesis. Comparing rhizome with root, flower, leaf or stem in F. dibotrys, 27 962 co-expressed differentially expressed genes(DEGs) were obtained. Among them, 23 515 DEGs of rhizome tissue-specific were enriched into 132 pathways and 13 unigenes were significantly enriched in biosynthesis of flavone and flavonol. In addition, we also identified 3 427 unigenes encoding 60 transcription factor(TFs) families as well as four unigenes encoding bHLH TFs were enriched in flavonoid biosynthesis. Our results greatly enriched the transcriptome database of plants, provided a reference for the analysis of key enzymes involved in flavonoid biosynthesis in plants, and will facilitate the study of the functions and regulatory mechanisms of key enzymes involved in flavonoid biosynthesis in F. dibotrys at the genetic level.

ABSTRACT

To explore the activity of essential oil extracted from Artemisia argyi (AAEO) in inducing the apoptosis of Candida albicans SC5314. The effect of AAEO on reactive oxygen species(ROS) and mitochondria membrane potential(MMP) of C. albicans SC5314 was detected by flow cytometry. Phosphatidylserine externalization was observed under fluorescence microscopic with Annexin-V/PI staining at the early stage of apoptosis in C. albicans. Metacaspase activity was observed under fluorescence microscopic with FITC-VAD-FMK staining at the early stage of apoptosis in C. albicans. C. albicans morphology was observed by DAPI nuclear staining and fluorescence microscopy. After intervention with 0.5 mL•L⁻¹ AAEO, apoptosis of C. albicans significantly increased, metacaspase activity increased, nuclear pyknosis and fragmentation, and intracellular ROS were significantly increased, and mitochondrial membrane potential decreased significantly. The certain concentrations of AAEO could induce the apoptosis of C. albicans.

ABSTRACT

<p><b>OBJECTIVE</b>The aim is to update our clinical recommendations for evidence-based language rehabilitation of people with aphasia, based on a systematic review of the literature from 1999 to 2015.</p><p><b>DATA SOURCES</b>Articles referred to in this systematic review of the Medline and PubMed published in English language literatures were from 1998 to 2015. The terms used in the literature searches were aphasia and evidenced-based.</p><p><b>STUDY SELECTION</b>The task force initially identified citations for 51 published articles. Of the 51 articles, 44 studies were selected after further detailed review. Six articles, which were not written in English, and one study related to laryngectomy rehabilitation interventions, were excluded from the study. This study referred to all the important and English literature in full.</p><p><b>RESULTS</b>Aphasia is the linguistic disability, which usually results from injuries to the dominant hemisphere of the brain. The rehabilitation of aphasia is until in the process of being debated and researched. Evidence-based medicine (EBM), EBM based on the clinical evidence, promotes the practice of combining the clinicians' first-hand experience and the existing objective and scientific evidence encouraging making decisions based on both empirical evidence and the scientific evidence. Currently, EBM is being gradually implemented in the clinical practice as the aim of the development of modern medicine.</p><p><b>CONCLUSIONS</b>At present, the research for the aphasia rehabilitation mainly focuses on the cognitive language rehabilitation and the intensive treatment and the precise treatment, etc. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for linguistic disability after traumatic brain injury and stroke, which can be used to develop linguistic rehabilitation guidelines for patients with aphasia.</p>

ABSTRACT

Axillary lymph nodes are the most common and initial site of metastasis of breast carcinoma. Precise axillary staging of breast carcinoma before initial treatment is crucial as it allows efficient identification for local and systemic treatment options, and provides prognostic information. Sentinel lymph node biopsy (SLNB) is an accurate minimally invasive technology for axillary staging. Although top evidence of high-quality clinical trials showed that SLNB could safely and effectively replace axillary lymph node dissection (ALND) for axillary negative patients with decrease in complications and improvement in quality of life, there are specific indications and contraindications for SLNB. Clinicians should balance the compliance of guideline and native clinical practice, especially for the circumstance of multifocal/multicentric lesion, breast biopsy history, and neoadjuvant chemotherapy. With the accumulation of clinical practice and new results of clinical trials, axillary therapy has changed from unique surgery to patient-tailored multi-disciplinary intervention, although ALND should be recommended traditionally if SLNB is positive. Intensive and accurate preoperative axillary staging is gradually valued by clinicians. Development of imaging modality especially ultrasonography and ultrasound-guided biopsy can identify some extra lymph node positive patients directly to ALND with avoidance of unnecessary SLNB. Thus, the positive rate of SLNB will decline significantly. It seems possible that axillary management will step into a noninvasive era abandoning SLNB in some patients with small breast cancer. In this article we review the prospect and guideline update of SLNB for patients with early-stage breast cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of electroacupuncture (EA) on the apoptosis of brain tissue cells and the expression of Caspase-3 in the rats with cerebral-cardiac syndrome (CCS).</p><p><b>METHODS</b>A total of 70 healthy SD rats were selected. Ten was randomly recruited as the sham-operation group, and the rest were used for CCS model preparation. Thirty successfully modeled rats were divided into the model group, the EA group, and the non-EA group, 10 in each group. The model was prepared using injecting collagenase + heparin into the caudate nucleus. Equal volume of 0.9% sodium chloride injection was injected to rats' caudate nucleus in the sham-operation group. EA was started on the 1st day of modeling. Shuigou (GV26), Fengfu (GV16), Neiguan (PC6), and Xinshu (BL15) were needled in the EA group. Four points in the hips were needled in the non-EA group. The EA needling lasted for 20 min each time, once daily, for 3 successive times. No EA was administered to the sham-operation group or the model group. The apoptosis of brain tissue around the hematoma and the expression of Caspase-3 were detected using TUNEL and immunochemical assay.</p><p><b>RESULTS</b>TUNEL cells could be occasionally seen with fewer Caspase-3 expression in the sham-operation group. More TUNEL positive cells appeared in the tissue around the hematoma of the model group with a large amount of Caspase-3 expression. The TUNEL positive cells and Caspase-3 expression were obviously less in the EA group than in the model group and the non-EA group (P < 0.01).</p><p><b>CONCLUSIONS</b>EA could inhibit the apoptosis of brain tissue cells in CCS rats. Its mechanisms might be associated with down-regulating the Caspase-3 expression of the brain tissue around the hematoma.</p>
