Cloning and subcellular location of the PnMYB1R1 gene from Panax notoginseng and expression analysis with different stresses / 药学学报

MYB transcription factors, one of the largest transcription factor families in plants, play an important role in signal transduction, plant growth and plant resistance. In this study a full-length cDNA of the PnMYB1R1 gene was cloned from Panax notoginseng. Sequence analysis, prokaryotic expression and purification, subcellular location, transcriptional activity analysis, tissue-specific analysis and expression analysis under different abiotic stresses was performed. The open reading frame (ORF) of PnMYB1R gene was 738 bp, encoding a protein of 245 amino acids with a predicted molecular mass (MW) of 27.0 kD. The sequence analysis and polygenetic analysis indicated that the PnMYB1R1 protein contains a conserved R3 domain, belonging to TRF-like protein in 1R-MYB-type transcription factors. The recombinant PnMYB1R1 protein was expressed in Escherichia coli BL21(DE3) cells using the prokaryotic expression vector pET28a-PnMYB1R1 and was purified. Subcellular localization analysis showed that PnMYB1R1 was localized in the nucleus. Transcriptional activity analysis indicated that the PnMYB1R1 transcription factor has transcriptional activation activity. Expression analysis indicated that PnMYB1R1 was primarily expressed in roots, followed by stems and leaves, and then rootlets. The expression level of PnMYB1R1 in root, stems, leaves and rootlets was influenced by salt, low temperature and drought treatment, while the abundance of PnMYB1R1 was significantly induced by salt stress in these tissues. These results provide valuable insights into the role of 1R-MYB transcription factors in plant defense.

Influence of visceral fat area on the prognosis of laparoscopic radical resection in patients with colorectal cancer / 医学研究生学报

Objective The factors influencing the prognosis of laparoscopic radical resection of colorectal cancer remain controversial. This study was to investigate the effect of visceral fat area (VFA) on the prognosis of laparoscopic radical resection of colorectal cancer and provide evidence for evaluating the prognosis of patients with colorectal cancer. Methods A retrospective analysis was made on the clinical data of 218 patients undergoing laparoscopic radical resection of colorectal cancer in the Department of Gastrointestinal Surgery of Affiliated Hospital of Southwest Medical University from March 2013 to June 2014. The patients were divided into VFA-S group (VFA<100cm2, n=106) and VFA-L group (VFA≥100m2, n=112) according to the measured VFA values. The basic clinical data of the two groups were compared and the short-term and long-term prognosis of VFA were evaluated by logistic regression and Cox regression models. Results The incidence of complication and the incidence of minor complications (13.2%, 9.4%) in VFA group were significantly lower than those in control group (27.7%, 19.6%), and the difference was statistically significant (P<0.05). The overall survival rate of patients in VFA group at 1 year, 3 years, and 5 years (98.1%, 87.7%, 70.8%) was significantly greater than that of control group (93.8%, 67.9%, 58.0%), and the difference was statistically significant (P< 0.05). The disease-free survival rate (98.1%, 84.0%, 70.8%) at 1 year, 3 years, and 5 years after surgery was significantly higher in VFA group than that in control group (92.0%, 67.9%, 58.0%), and the difference was statistically significant (P <0.05). The Kaplan-Meier curve showed that the overall survival and disease-free survival (58.91 months, 57.82 months) in VFA group were significantly greater than those in control group (51.61 months, 50.60 months), and the difference was statistically significant (P<0.05). The overall survival and disease-free survival were associated with ASA classification, differentiation, TNM stage, and VFA (P<0.05). Conclusion VFA has an impact on short-term and long-term prognosis after laparoscopic radical resection of colorectal cancer. VFA≥100cm2 indicates that patients have a high possibility of postoperative complications and poor prognosis.

Study on ecological stereoscopic cultivation mode of Amomum villosum-Dimocarpus longan / 中国中药杂志

In order to set up a technical standard for planting Amomum villosum in wood forest in the future, we analyzed the relationship between the ecological factors and the yield of A. villosum planted in five Dimocarpus imocarpus longan wood forests and five miscellaneous wood forests in Yangchun city, to find out the dominant factors that affect the yield of A. villosum. The results showed that agricultural measures of fertilization, artificial irrigation and removing the old plants were positively correlated with the yield of A. villosum, the pesticide spraying and soil pH value were negatively correlated with the yield of A. villosum. But the effects of ecological factors on the yield were not significantly. High yield regions are generally located in the ravine, two sides of mountain stream and other places where water is more adequate. The slope of cultivated field with high yield is generally less than 30°, lighting and ventilation are more appropriate; soil type is generally sandy or loam, shade density is generally about 50%, and pollinators are many in quantity and variety. And we found that there was a large difference in mineral nutrient contents of soils among ten plantations. Results indicate that the yield of A. villosum is determined by the combination of each ecological factor. Suitable light intensity, moisture, ventilation and reasonable fertilization are conductive to increase the yield of A. villosum, but the use of pesticides and soil alkalization hinder the increase of A. villosum production. Too high shade density and the abuse of pesticides may be the main reason for limiting the yield of A. villosum planted in D. longan wood forests. This study has obtained key techniques of the ecological stereoscopic cultivation mode of A. villosum-D. longan, which lays a theoretical foundation for the guidance of farmers in planting A. villosum in the D. Longan forest in the future.

Effects of Aconitum coreanum polysaccharides on TGF-β induced endothelial-mesenchymal transition and its mechanisms / 中国药理学通报

Aim To investigate the protective effect of Aconitum coreanum polysaccharides ( ACP) on TGF-β induced endothelial-mesenchymal transition ( EndMT) and its underlying mechanism. Methods HUVECs EndMT model was reproduced by 10 μg·L-1 TGF-β cultured for 72 h in vitro. The effect of ACP(50, 100, 200 mg·L-1) at various concentrations on TGF-β in-duced EndMT of HUVECs was explored. CCK8 assay was employed to detect the cell viability of HUVECs stimulated by ACP. Scratch test was used to analyze the migration ability of cells. The expressions of CD31, α-SMA, Smad2/3, p-Smad2/3 were deter-mined by Western blot. Results CCK-8 assay showed that various concentrations of ACP could promote HU-VECs viability obviously by 10 μg·L-1 TGF-β cul- tured for 36 h. Scratch test showed that TGF-β en-hanced transfer ability of HUVECs significantly, while this case was apparently reversed under the costimula-tion of TGF-β and ACP. Western blot showed that CD31 expression decreased significantly, and the ex-pressions of α-SMA, p-Smad2, p-Smad3 increased significantly, and this phenomenon could be regressed with ACP. Conclusion ACP can inhibit EndMT in HUVECs induced by TGF-β clearly, and the mecha-nism is related to down-regulation of p-Smad2, p-Smad3.

DREAM: a multifunctional transcriptional regulator / 生理学报

DREAM (downstream regulatory element antagonist modulator), Calsenilin and KChIP3 (potassium channel interacting protein 3) belong to the neuronal calcium sensor (NCS) superfamily, which transduces the intracellular calcium signaling into a variety of activities. They are encoded by the same gene locus, but have distinct subcellular locations. DREAM was first found to interact with DRE (downstream regulatory element) site in the vicinity of the promoter of prodynorphin gene to suppress gene transcription. Calcium can disassemble this interaction by binding reversibly to DREAM protein on its four EF-hand motifs. Apart from having calcium dependent DRE site binding, DREAM can also interact with other transcription factors, such as cAMP responsive element binding protein (CREB), CREB-binding protein (CBP) and cAMP responsive element modulator (CREM), by this concerted actions, DREAM extends the gene pool under its control. DREAM is predominantly expressed in central nervous system with its highest level in cerebellum, and accumulating evidence demonstrated that DREAM might play important roles in pain sensitivity. Novel findings have shown that DREAM is also involved in learning and memory processes, Alzheimer's disease and stroke. This mini-review provides a brief introduction of its discovery history and protein structure properties, focusing on the mechanism of DREAM nuclear translocation and gene transcription regulation functions.

Study on the Effect of Iodine on the Acid Content Titration in Preparations / 中国药房

OBJECTIVE:To study on the effect of iodine (I2) on the acid content titration in the preparations,and establish a method of eliminating I2 for accurate determination of total acid content. METHODS:Taking an example of Onychomycosis paint,I2 was reduced by sodium sulfide(Na2S)before titration analysis and compared with the standard method of traditional titration. Ac-cording to the two methods of consumption of different sodium hydrate(NaOH)volume,the effect of I2 on the determination of to-tal acid content in preparation was explored. RESULTS:Reduction method of Na2S can eliminate the effect of I2,the color of indica-tor changed acutely. The determined total acid and theoretical values were the same;the linear range of the concentration of total ac-id in onychomycosis paint was 3.926-7.290 mol/ml(r=0.9999);RSDs of precision,stability and reproducibility tests were no more than 0.04%;average recovery was 99.91%-100.10%(RSD=0.036%,n=6). CONCLUSIONS:I2 has effect on the determina-tion of total acid content,the disproportion reaction of I2 can generate hydriodic acid that can interfere acid-base titration's results, and the generated hydriodic acid can oxidize indicator to make the end point is not sensitive or even invariant color. Using Na2S can eliminate the effect of iodine on the preparation of acid titration,which has improved precision and reproducibility with accurate and reliable determination results.

Establishment of An Alloxan-induced Diabetes Model in Daphnia Pulex / 中国医学科学院学报

Objective To establish a Daphnia model of alloxan-induced diabetes. Methods Daphnia were exposed to three different concentrations of alloxan (3, 5, and 10 mmol/L) for 30 minutes. Blood glucose and survival rate were recorded for 72 hours after alloxan insult. Sequence analysis and phylogenetic inference for glucose transporters (GLUT) were clustered with the maximum-likelihood method. Using reverse transcription and quantitative polymerase chain reaction techniques, we investigated the transcriptional changes of GLUT at 12 hours after alloxan (5 mmol/L) exposure. Results Compared with control, 3 mmol/L, and 5 mmol/L as well as 10 mmol/L alloxan initially induced transient blood glucose decline by 15% for 2 hours and 12 hours respectively. In Daphnia with 5 and 10 mmol/L alloxan, their blood glucose was persistently raised by about 150% since after 24-hour insult. Survival rate of Daphnia exposure to alloxan with concentrations of 3, 5, and 10 mmol/L were 90%, 75%, and 25% respectively. We predicted seven GLUT genes in the Daphnia genome and successfully amplified them using real-time polymerase chain reaction. Two of seven GLUT transcripts were down-regulated in Daphnia with 5 mmol/L alloxan-induced diabetes. Conclusion Alloxan-induced diabetes model was successfully established in the Daphnia pulex, suggesting diabetes-relevant experiments can be conducted using Daphnia.
