Long non-coding RNAs(lncRNAs)can be involved in regulating gene expression through multiple interactions with DNA,RNA or proteins.Studies have shown that lncRNAs not only regulate innate immune response,but also regulate immune cell development and adaptive immunity.According to recent reports,a number of lncRNAs play a role in the pathogenesis of immune-mediated inflammatory diseases,including systemic lupus erythematosus(SLE),and may become a diagnostic marker and prognostic reference for diseases.This paper summarizes the research progress of lncRNAs in SLE,with the hope of providing more new ideas and methods for the study of SLE.

OBJECTIVEWith the objective of discovering novel putative chromosomal regions and special genes involved in the carcinogenesis, progression and metastasis of laryngeal squamous cell cancer (LSCC).

METHODSDNA copy profile of LSCC were obtained and analyzed by comparative genomic hybridization (CGH) and a computerized digital image analysis system. cDNA microarray of LSCC was performed and the profile was analyzed by Hierarchical clustering.

RESULTSCGH analysis showed average-12.9 gains and losses of chromosomes in LSCC. Relatively high frequencies of gains were found at 3q15-21 (14/18), 5p12-13 (11/18), 8q22-24 (6/18), 11q12-13 (8/18), 15q21-23 (7/18) and 18p11 (8/18), while those of losses at 1p13-21 (8/18), 3p21-23 (14/18), 5q21-22 (14/18), 9p12-pter (11/18) and 13q21-31 (8/18). Hierarchical clustering analysis showed that the differentially expressed genes were segregated into three groups. Three genes differentially expressed in process I (normal tissue to cancer) and process II (cancer to lymph node metastasis), and the Cy5/Cy3 ratios of twelve genes were either higher than 5.0 or lower than 0.2 in process I or process II. The fifteen special genes were first reported possibly to be the relationships with LSCC. In particular, 4 genes of them, which were cytochrome C oxidase Va, PPBP, EPHX2 and PON1, were first reported to correlate with tumorigenesis. SH3GL2, which was one of the 15 special genes, was located at one of the special chromosome regions, 9p12-pter.

CONCLUSIONThe important genes and special chromosomal aberrances might provide us a clue for further investigation of carcinogenesis, progression and metastasis in LSCC.

OBJECTIVETo study the relationship between Ureaplasma urealyticum (UU) infection in the lower respiratory tract and the incidence of bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants with respiratory distress syndrome (RDS).

METHODSSeventy-three VLBW infants diagnosed with neonatal RDS, who had received at least one dose of pulmonary surfactant, as well as mechanical ventilation, and were hospitalized for over 28 days, were recruited. Endotracheal aspirates were obtained from the lower respiratory tract and examined by real-time PCR to detect UU DNA. The infants were divided into UU infection and non-UU infection groups according to examination results. Clinical characteristics and the incidence of BPD were compared between the two groups.

RESULTSCompared with the non-UU infection group, the UU infection group had a higher rate of maternal vaginal delivery, higher incidence of recurrent nosocomial pulmonary infection and premature rupture of membranes (PROM), and longer durations of PROM, oxygen supplementation, and hospital stay; in addition, the UU infection group had higher plasma IgM level, leukocyte count, and neutrophil count within 3 hours after birth. Among 73 VLBW infants, 45 developed BPD; the incidence of BPD in the UU infection group was 90% (19/21), versus 50% (26/52) in the non-UU infection group (P<0.01).

CONCLUSIONSUU infection in the lower respiratory tract increases the incidence of BPD in VLBW infants with RDS.

Background/Aims: Direct‐acting antivirals (DAAs) have been approved for hepatitis C virus (HCV) treatment in patients with end-stage renal disease (ESRD) on hemodialysis. Nevertheless, the complicated comedications and their potential drug-drug interactions (DDIs) with DAAs might limit clinical practice in this special population. Methods: The number, class, and characteristics of comedications and their potential DDIs with five DAA regimens were analyzed among HCV-viremic patients from 23 hemodialysis centers in Taiwan. Results: Of 2,015 hemodialysis patients screened in 2019, 169 patients seropositive for HCV RNA were enrolled (mean age, 65.6 years; median duration of hemodialysis, 5.8 years). All patients received at least one comedication (median number, 6; mean class number, 3.4). The most common comedication classes were ESRD-associated medications (94.1%), cardiovascular drugs (69.8%) and antidiabetic drugs (43.2%). ESRD-associated medications were excluded from DDI analysis. Sofosbuvir/velpatasvir/voxilaprevir had the highest frequency of potential contraindicated DDIs (red, 5.6%), followed by glecaprevir/pibrentasvir (4.0%), sofosbuvir/ledipasvir (1.3%), sofosbuvir/velpatasvir (1.3%), and elbasvir/grazoprevir (0.3%). For potentially significant DDIs (orange, requiring close monitoring or dose adjustments), sofosbuvir/velpatasvir/voxilaprevir had the highest frequency (19.9%), followed by sofosbuvir/ledipasvir (18.2%), glecaprevir/pibrentasvir (12.6%), sofosbuvir/velpatasvir (12.6%), and elbasvir/grazoprevir (7.3%). Overall, lipid-lowering agents were the most common comedication class with red-category DDIs to all DAA regimens (n=62), followed by cardiovascular agents (n=15), and central nervous system agents (n=10). Conclusions HCV-viremic patients on hemodialysis had a very high prevalence of comedications with a broad spectrum, which had varied DDIs with currently available DAA regimens. Elbasvir/grazoprevir had the fewest potential DDIs, and sofosbuvir/velpatasvir/voxilaprevir had the most potential DDIs.

The combination of Angelicae sinensis Radix (Danggui, DG) and Astragali Radix (Huangqi, HQ) is a popular herb pair commonly used in clinic for the treatment of blood deficiency syndrome in China. The aim of this paper is to study the interaction of DG and HQ nourishing and tonifying blood effects by response surface method. The blood deficiency mice were induced by injecting N-acetylphenylhydrazine (sc) and cyclophosphamide (ip). The blood deficiency mice were administrated intragastrically with DG-HQ extracts (0:1, 1: 5, 2:5, 2:3, 1:1, 3:2, 5:2, 5:1, 1:0). The changes of the peripheral blood indexes and organ indexes were observed. The indexes were integrated by comprehensive index method; the interactions of DG and HQ were analyzed by the response surface diagram established with Matlab software. The results showed that DG and HQ at most of their combination ratios had synergic effect. Within the range of 1:5 - 5:1, all of the extracts of DG-HQ showed synergic effect, and among which, high-doses had better effects than low-doses. The highest value (-1) of the synergic effect was showed when DG was 10 - 40 g at the same time of HQ as 90 -180 g, and DG was 50 - 100 g at the same time of HQ as 20 - 100 g. DG-HQ at all combination dosages within Chinese Pharmacopeia (DG: 6 - 12 g, HQ: 9 - 30 g) had certain synergic effect, and Danggui Buxue Decoction (DG: 6 g, HQ: 30 g) also was at this range. The results provided scientific basis to the clinical application of DG and HQ. And the response surface method was firstly applied to quantitatively evaluate the bio-activity change of herb combination, which provided a novel way for modern basic research on the interaction of herbs.
