Circular RNAs (circRNAs) are endogenous non-coding RNAs with covalently closed structures, which have important functions in plants. However, their biogenesis, degradation, and function upon treatment with gibberellins (GAs) and auxins (1-naphthaleneacetic acid, NAA) remain unknown. Here, we systematically identified and characterized the expression patterns, evolutionary conservation, genomic features, and internal structures of circRNAs using RNase R-treated libraries from moso bamboo (Phyllostachys edulis) seedlings. Moreover, we investigated the biogenesis of circRNAs dependent on both cis- and trans-regulation. We explored the function of circRNAs, including their roles in regulating microRNA (miRNA)-related genes and modulating the alternative splicing of their linear counterparts. Importantly, we developed a customized degradome sequencing approach to detect miRNA-mediated cleavage of circRNAs. Finally, we presented a comprehensive view of the participation of circRNAs in the regulation of hormone metabolism upon treatment of bamboo seedlings with GA and NAA. Collectively, our study provides insights into the biogenesis, function, and miRNA-mediated degradation of circRNAs in moso bamboo.

Objective: To investigate the effect of Toll-like receptor 9 (TLR9) on high glucose-induced retinal ganglion cells-5 (RGC-5) apoptosis and the inhibitory effects of small interfering RNA-TLR9 (si-TLR9) on apoptosis. Methods: RGC-5 cells were divided into normal control group, high glucose group, high glucose+ negative control group and high glucose+ si-TLR9 group which cells were respectively dealt with normal culture medium, high glucose medium, transfection of non-specific siRNA under high glucose and transfection of siRNA-TLR9 under high glucose.The expression of TLR9 mRNA was detected by real time PCR; the survival rate of the cells was evaluated by MTT assay; the apoptotic rate of the cells was detected by flow cytometry; the caspase-3 activity in the cells was detected by related kit, and the expressions of TLR9, B cell lymphoma (bcl-2), bcl-2 associated X protein (bax), p38 mitogen-activated protein kinases (p38MAPK) and phosphorylated (p)-p38MAPK proteins were detected by Western blot. Results: The expressions of TLR9 mRNA and protein in the high glucose+ si-TLR9 group were significantly decreased in comparison with the high glucose+ negative control group (both at P<0.05). The cell survival rate of the high glucose group and high glucose+ negative control group was (78.36±5.13)% and (75.12±4.25)%, respectively, which was significantly lower than (95.48±7.25)% in the normal control group, and that in the high glucose+ si-TLR9 group was (86.58±5.32)%, which was significantly reduced in comparison with the high glucose+ negative control group (all at P<0.05). The apoptotic rate of the cells in the high glucose group and high glucose+ negative control group was (13.23±1.22)% and (12.52±1.38)%, respectively, which was significantly higher than (2.26±0.15)% of the normal control group, and apoptotic rate in the high glucose+ si-TLR9 group was (7.15±0.24)%, which was significantly lower than that in high glucose+ negative control group (all at P<0.05). The expression of bax in the cells of the high glucose+ si-TLR9 group was significantly decreased, and the expression of bcl-2 in the cells of the high glucose+ si-TLR9 group was significantly increased in comparison with the high glucose+ negative control group (both at P<0.05). Caspase-3 activity in the cells was significantly decreased in the high glucose+ si-TLR9 group compared with the high glucose+ negative control group (P<0.05). The relative expression of p-p38MAPK in the cells was significantly decreased in the high glucose+ si-TLR9 group compared with the high glucose+ negative control group (P<0.05). Conclusions Down-regulation of TLR9 expression in the RGC-5 cells can inhibit the apoptosis induced by high glucose probablely by suppressing p38MAPK signaling pathway.

Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman’s rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

Objective To investigate the application of statistical methods in clinical research articles of oncology in China. Methods The core journals in Chinese oncology journals were retrieved in "Wanfang Data", and the application of statistical methods in the clinical research articles published in the first issue of 2017 were analyzed,including the selection of statistical indicators,the selection of statistical methods and the interpretation of statistical results. Results A total of 176 clinical research articles from 24 journals were taken into the study.In the selection of statistical indicators, 12.6 %(16 articles) used the description method of normal distribution data for the skewness distribution measurement data; 37.9 % (47 articles) described the count data with samples<20 as a percentage; 14.5 % (9 articles) replaced the constituent percentages with composition ratios. In the selection of statistical methods, 10.3 % (12 articles) did not perform analysis of variance when comparing among multiple groups, and the t test was used to compare each other directly. 15.1 % (8 articles) disregarded the preconditions of the use of the χ 2test. In the interpretation of statistical results, 18.4 % (27 articles) confused the statistical significance with biological significance. Conclusions The statistical problems are widespread in Chinese oncology clinical research articles,involving the entire process from study design to interpretation of results. Scientific research management departments, clinical researchers, and journal editorial board need to work together to improve the scientificity of clinical scientific research results of oncology in China.
