ABSTRACT
Gloeostereum incarnatum has edible and medicinal value and was first cultivated and domesticated in China. We sequenced the G. incarnatum monokaryotic strain GiC-126 on an Illumina HiSeq X Ten system and obtained a 34.52-Mb genome assembly sequence that encoded 16,895 predicted genes. We combined the GiC-126 genome with the published genome of G. incarnatum strain CCMJ2665 to construct a genetic linkage map (GiC-126 genome) that had 10 linkage groups (LGs), and the 15 assembly sequences of CCMJ2665 were integrated into 8 LGs. We identified 1912 simple sequence repeat (SSR) loci and detected 700 genes containing 768 SSRs in the genome; 65 and 100 of them were annotated with gene ontology (GO) terms and KEGG pathways, respectively. Carbohydrate-active enzymes (CAZymes) were identified in 20 fungal genomes and annotated; among them, 144 CAZymes were annotated in the GiC-126 genome. The A mating-type locus (MAT-A) of G. incarnatum was located on scaffold885 at 38.9 cM of LG1 and was flanked by two homeodomain (HD1) genes, mip and beta-fg. Fourteen segregation distortion markers were detected in the genetic linkage map, all of which were skewed toward the parent GiC-126. They formed three segregation distortion regions (SDR1–SDR3), and 22 predictive genes were found in scaffold1920 where three segregation distortion markers were located in SDR1. In this study, we corrected and updated the genomic information of G. incarnatum. Our results will provide a theoretical basis for fine gene mapping, functional gene cloning, and genetic breeding the follow-up of G. incarnatum.

ABSTRACT
OBJECTIVE@#To measure the level of serum Semaphorin 3A (Sema3A) and to analyze the relationship between serum Sema3A and systemic lupus erythematosus (SLE) with thrombocytopenia.@*METHODS@#The concentration of serum Sema3A was detected by enzyme-linked immuno sorbent assay (ELISA) in 170 SLE patients, 50 Sjögren's syndrome (SS) patients, 19 hypersplenism (HS) patients and 150 healthy controls (HC). Based on the presence of thrombocytopenia and whether the thrombocytopenia was in remission, the SLE patients were divided into three groups: SLE with thrombocytopenia (41 cases), SLE with thrombocytopenia remission (28 cases), and SLE without thrombocytopenia (101 cases). According to whether there was thrombocytopenia, the SS patients were divided into SS with thrombocytopenia (18 cases) and SS without thrombocytopenia (32 cases). The 28 SLE patients who underwent bone marrow aspiration biopsy were divided into two groups from the aspect of whether the bone marrow hyperplasia was normal (19 cases) or low (9 cases), as well as from the aspect of whether the maturity disturbance of megakaryocyte was positive (8 cases) or negative (20 cases). The serum Sema3A levels in SLE, SS, HS with HC were compared, meanwhile, the correlation between serum Sema3A level and platelet (PLT) in the patients with different diseases analyzed.@*RESULTS@#(1) Serum Sema3A levels in SLE were significantly lower than in HC [(3.84±2.76) μg/L vs. (6.96±2.62) μg/L, P < 0.001], serum Sema3A levels in SS were also obviously lower than in HC [(4.35±3.57) μg/L vs. (6.96±2.62) μg/L, P < 0.001], and in HS it was lower than HC at a certain extant [(5.67±2.26) μg/L vs. (6.96±2.62) μg/L, P=0.041]. (2) Serum Sema3A levels in SLE were slightly lower than in SS, but there was no significant difference [(3.84±2.76) μg/L vs. (4.35±3.57) μg/L, P=0.282]. However, when compared with HS, serum Sema3A levels in SLE were significantly lower [(3.84±2.76) μg/L vs. (5.67±2.26) μg/L, P=0.006]. (3) Serum Sema3A concentration in SLE with thrombocytopenia was significantly lower than in SLE with thrombocytopenia remission [(1.28±1.06) μg/L vs. (3.83±2.65) μg/L, P < 0.001], and in SLE patients without thrombocytopenia [(1.28±1.06) μg/L vs. (4.87±2.60) μg/L, P < 0.001]. There was no significant difference between SLE with thrombocytopenia remission and SLE without thrombocytopenia [(3.83±2.65) μg/L vs. (4.87±2.600 μg/L, P=0.123]. Serum Sema3A concentration in SLE with thrombocytopenia was slightly lower than in SS with thrombocytopenia, but there was no significant difference [(1.28±1.06) μg/L vs. (1.68±1.11) μg/L, P=0.189]. (4) Strong positive correlations were found between serum Sema3A and PLT in SLE (r=0.600, P < 0.001). Positive correlations were also found between serum Sema3A and PLT in SS (r=0.573, P < 0.001). However, there was no such correlation showed in HS patients (P=0.393). (5) There was no significant difference of serum Sema3A concentration in SLE whether the bone marrow hyperplasia was normal or low. And the same situation appeared in the patients whether the maturity disturbance of megakaryocyte was positive or negative (P>0.05).@*CONCLUSION@#Serum Sema3A was significantly reduced in SLE patients, and it was highly correlated with the blood damage. Similar conclusions could be drawn in patients with SS. The serum level of Sema3A was generally decreasing in desmosis which merged thrombocytopenia, and was obviously positive correlated with platelet counts.

<p><b>BACKGROUND</b>Sedation for the coblation-assisted upper airway procedure has lacked easy modulation between appropriate pain control and airway protection. This study aimed to compare the effectiveness of dexmedetomidine versus target controlled propofol infusion in providing sedation during a coblation-assisted upper airway procedure.</p><p><b>METHODS</b>In a prospective, randomized trial, 60 adult patients with obstructive sleep apnea syndrome due to undergoing a coblation-assisted upper airway procedure were enrolled and randomly allocated to receive dexmedetomidine, 1.0 µg/kg over 10 minutes and maintain dosage 0.7 µg×kg(-1)×h(-1) (n=30) or propofol target controlled infusion (n=30). Satisfaction with the analgesia and tolerance of the procedure by the patient, as assessed by a visual analogue scale, were evaluated as primary outcomes. Cardiopulmonary parameters and some side effects were monitored and recorded.</p><p><b>RESULTS</b>Both groups of 30 patients had comparable demographics and initial parameters. Patients in the propofol group reported more pain (P<0.05), tolerated the procedure less well (P<0.05), and were less satisfied with the different stages of procedure (P<0.05 or P<0.01). Changes in mean arterial pressure and heart rate were more dramatic in the propofol group (P<0.05). The dexmedetomidine group experienced fewer airway events and less respiratory depression than did the propofol group.</p><p><b>CONCLUSION</b>Dexmedetomidine in conjunction with local anesthesia offered better analgesia and conscious sedation for a coblation-assisted upper airway procedure as well as less airway obstruction, apnea and greater haemodynamic stability.</p>
