AIM:To analyse the chemical constituents of volatile components from Viola yedoensis Makino. METHODS: The essential oils from Viola yedoensis Makino(collected from Jinhua city and Changchun city) were extracted by steam distillation.The chemical compounds were separated and identified by GC-MS.The relative content of each component was determined by area normalization. RESULTS: Twenty-five and twenty-three constituents were separated from Viola yedoensis Makino collected from Changchun city and Jinhua city;twenty-one and twenty-two compounds were identified respectively.The ratios of identification of total compounds were 88.00% and 91.30% respectively. CONCLUSION: There are significant difference between two varieties of Viola yedoensis Makino,the main coustituents in each plant are n-hexadecanoic acid(16.77%)and phytol(26.97%).

Objective To establish the quality standard of Radix Toddaliae Asiaticae. Methods Thin layer chromatography ( TLC) and high performance liquid chromatography ( HPLC) were used to identify and determine chloride nitidine and toddalolactone in Radix Toddaliae Asiaticae. The moisture and total ash contents were detected according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition) . Results Toddalolactone and chloride nitidine were detectable by TLC, the spots were clear and the dissociation was good. The established HPLC method was simple and accurate. The linear ranges of toddalolactone and chloride nitidine in Radix Toddaliae Asiaticae were 2.84~42.6 μg/mL and 25.6~385 μg/mL, and their recovery rates were 99.2 % ( RSD=1.12%) and 100 % ( RSD=0.71%) , respectively. The content of moisture was in the range of 75.8~98.9 mg/g and that of total ash was in the range of 12.4~33.6 mg/g. Conclusion The developed method is specific and accurate, and can provide useful reference for establishing quality standard of Radix Toddaliae Asiaticae.

In recent years, large numbers of non-coding RNAs (ncRNAs) have been identified in C. elegans but their functions are still not well studied. In C. elegans, CEP-1 is the sole homolog of the p53 family of genes. In order to obtain transcription profiles of ncRNAs regulated by CEP-1 under normal and UV stressed conditions, we applied the 'not-so-random' hexamers priming strategy to RNA sequencing in C. elegans, This NSR-seq strategy efficiently depleted rRNA transcripts from the samples and showed high technical replicability. We identified more than 1,000 ncRNAs whose apparent expression was repressed by CEP-1, while around 200 were activated. Around 40% of the CEP-1 activated ncRNAs promoters contain a putative CEP-1-binding site. CEP-1 regulated ncRNAs were frequently clustered and concentrated on the X chromosome. These results indicate that numerous ncRNAs are involved in CEP-1 transcriptional network and that these are especially enriched on the X chromosome in C. elegans.

Objective:To investigate the correlation between perioperative new onset atrial fibrillation and the prognosis of colorectal cancer.Methods:This study involved 180 colorectal cancer patients undgoing radical resection at the Department of Gastrointestinal Surgery, Longyan First Hospital from Jan 2014 to Jan 2015. Among them, 47cases suffered from perioperative new onset atrial fibrillation.Results:The perioperative new onset atrial fibrillation group had a higher mean age and a higher mean postoperative C-reactive protein level than the control group ( t=-3.080, P=0.002; t=-2.184, P=0.030). Hence these patients had a longer hospital stay ( t=-5.072, P=0.001; t=-2.577, P=0.011). Multivariate analysis showed that postoperative new onset atrial fibrillation, high postoperative mean C-reactive protein level, poor tumor differenciation and late tumor stage were independent risk factors for the prognosis of colorectal cancer ( HR=1.835, P=0.018; HR=1.008 P=0.017; HR=1.950 P=0.046; HR=1.300, P=0.047). The median survival time of perioperative new onset atrial fibrillation group and control group were 59.05 months and 63.23 months, respectively ( P=0.005). Conclusions:Colorectal cancer patients suffering from perioperative new onset atrial fibrillation were more common among advanced age and high postoperative mean C-reactive protein level with higher all-cause mortality.

Objective:To investigate the risk factors affecting the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer.Methods:Clinicopathological data of patients diagnosed with gastric adenocarcinoma and treated with radical surgery at our hospital between January 2017 and December 2018 were retrospectively collected, and 96 patients were finally included in the study according to the inclusion and exclusion criteria.Patients were divided into a completed chemotherapy group and an uncompleted chemotherapy group depending on whether they had completed 6 cycles of adjuvant chemotherapy after surgery.The optimal cut-off value was derived from the receiver operating characteristic(ROC)curve, and the Youden Index was calculated.Relevant factors that might affect the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer were included in univariate and multivariate Logistic regression analyses to identify independent risk factors affecting the completion of postoperative adjuvant chemotherapy in gastric cancer patients.The Kaplan-Meier(K-M)method was used to plot the survival curves for the groups, and the log-rank test was used to compare the survival rates between the groups.Results:A total of 96 patients, aged 60-89 years, with a mean age of(70.3±7.0)years, were included.Sixteen patients completed postoperative adjuvant chemotherapy, while 80 patients did not.The following analysis was performed on clinicopathological data of patients in the two groups.Univariate Logistic regression analysis showed that patient age ≥70 years( OR=8.135, 95% CI: 1.735-38.153, P=0.008)or a preoperative prognostic nutritional index(PNI)score <49.5( OR=4.765, 95% CI: 1.549-14.656, P=0.006)affected the completion of postoperative adjuvant chemotherapy.The risk factors that might affect the completion of postoperative adjuvant chemotherapy in elderly gastric cancer patients were analyzed using multivariate Logistic regression and the results showed that age ≥70 years( OR=9.815, 95% CI: 1.947-49.485, P=0.006)and a preoperative PNI score <49.5( OR=5.895, 95% CI: 1.711-20.305, P=0.005)were independent risk factors hindering the completion of postoperative adjuvant chemotherapy. Conclusions:Age ≥70 years and PNI<49.5 are independent risk factors for the completion of postoperative adjuvant chemotherapy.Failure to complete postoperative adjuvant chemotherapy is associated with a poor prognosis.PNI is a valid predictor for whether postoperative adjuvant chemotherapy will be completed and helps to screen chemotherapy patients who need nutritional intervention.

Pancreatic lipase (PL), a crucial enzyme in the digestive system of mammals, has been proven as a therapeutic target to prevent and treat obesity. The purpose of this study is to evaluate and characterize the PL inhibition activities of the major constituents from Fructus Psoraleae (FP), one of the most frequently used Chinese herbs with lipid-lowering activity. To this end, a total of eleven major constituents isolated from Fructus Psoraleae have been obtained and their inhibition potentials against PL have been assayed by a fluorescence-based assay. Among all tested compounds, isobavachalcone, bavachalcone and corylifol A displayed strong inhibition on PL (IC < 10 μmol·L). Inhibition kinetic analyses demonstrated that isobavachalcone, bavachalcone and corylifol A acted as mixed inhibitors against PL-mediated 4-methylumbelliferyl oleate (4-MUO) hydrolysis, with the K values of 1.61, 3.77 and 10.16 μmol·L, respectively. Furthermore, docking simulations indicated that two chalcones (isobavachalcone and bavachalcone) could interact with the key residues located in the catalytic cavity of PL via hydrogen binding and hydrophobic interactions. Collectively, these finding provided solid evidence to support that Fructus Psoraleae contained bioactive compounds with lipid-lowering effects via targeting PL, and also suggested that the chalcones in Fructus Psoraleae could be used as ideal leading compounds to develop novel PL inhibitors.
