Long non-coding RNA ( LncRNA) is a class of transcript (>200 nucleotides) that do not encode proteins. It plays an important role in epigenetic regulation and gene expression at transcriptional or post transcriptional level. The abnormal expression of LncRNA may lead to various pathological processes. Diabetic retinopathy ( DR ) is a multifactorial disease. Recent studies have shown that many specific expressions of LncRNAs are closely related to the genesis of DR. In this review, we summarized the recent advances in the function of LncRNA, the regulatory mechanisms of LncRNA involved in the development of DR, and the related therapies.

Objective To explore the mechanism of effects of cardiac sympathetic anesthesia on left ventricular ejection fraction(LVEF) and left cardiac cavity size of patients with dilated cardiomyopathy.Method 121 consecutive patients with dilated cardiomyopathy were divided into cardiac sympathetic nerve blockade group(TEA group) and control group(c group).In TEA group,5% lidocaine was injected into thoracic epidural cavity for about 4 to 8 weeks in addition with routine therapy.In c group,only routine therapy was used.We observe the changes of LVEF and left cardiac cavity size before and after treatment in both groups. Result In TEA group,after anesthesia,LVEF was increased from(31.3± 12.8) to(47.3± 21.3),P<0.001;left ventricular end- diastolic diameter was reduced from(69.1± 7.1)to (65.1± 8.0),P<0.001;left atrial diameter was decreased from(44.0± 6.2)to(39.4± 7.2),P< 0.001. Conclusion Cardiac sympathetic anesthesia can effectively improve the ejection performance of dilated cardiomyopathy and make the dilated cardiac cavity turn to normal level.

To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.

To standardize the harvest ways of Dendrobium officinale and improve the quality and yield of D. officinale, a field experiment was carried out to study the effect of two kinds of harvest ways, which were keeping some of the axial shoot and harvesting all of the shoot by the end of the year. Then, the agronomic traits and yield were measured and the contents of polysaccharides and extractum were determined. The results showed that the harvest ways significantly affected the growth of D. officinale. Keeping some of the axial shoot could significantly improved the number of sprout, stem length, internode number and the internodal length, which also triggered increase the weight of fresh stems, leaves and the total of them and dry stems in per unit area, but it could not promote the stem diameter and the polysaccharide content in stems. Keeping some of the axial shoot moderately was conducive to the improvement of the production of medicinal materials in the process of harvesting by promoting the germination and growth of new buds, and to ensure the polysaccharide content by regulating the illumination and the density of cultivation.

AIM: To investigate the use of therapy ultrasound to enhance nonviral gene delivery. METHODS: Endothelial cells (EC) and vascular smooth muscle cells (VSMC) were cultured in 6-well plates. Plasmid (pcDNA3.1/His/LacZ) with or without microbubbles at the different concentrations was transfected into the cells with the use of ultrasound for 1 min at 2 MHz, 1.8 mechanical index (MI). Additional controls included ultrasound alone, microbubble alone and microbubble plus plasmid. The rate of blue cells and the activities of ?-Gal were measured. In addition, cell viability was detected with different time from 1 to 30 min of ultrasound irradiation and the different concentrations of microbubbles. RESULTS: In the group of ultrasound with microbubble, the rate of blue cells and activity of ?-Gal markedly increased by 60% and 9-fold, respectively. Microbubbles at concentration of 10% led to the highest transfection effect. Ultrasoud exposure at 1 to 30 minute had no cell toxic effects, while microbubbles at the concentration of 50% had significant effect on cell survival. CONCLUSIONS: Albumin-coated microbubbles markedly enhance gene delivery by therapeutic ultrasound-mediated microbubble destruction, which can be used as a safe and practicality vectors in gene therapy.

OBJECTIVETo make full use of the plant resources of Panax notoginseng, nutritional compositions and mineral elements were analyzed in aerial part of P. notoginseng from different areas in Yunnan.
METHODUsing the national standard method, water, ash, crude fat, crude fiber, crude protein and mineral elements were determined in aerial part of P. notoginseng from different growing areas.
RESULTResults showed that there were higher contents of crude fiber and crude protein, and lower content of crude fat in the stems and flowers of P. notoginseng. Meanwhile, a large number of mineral elements were determined in two locations of P. notoginseng, and the contents of Zn, Fe, Mn, Ca and Mg were obvious higher among these mineral elements.
CONCLUSIONThis study showed that the stems and flowers of P. notoginseng were nutritious and suggested that the aerial part may be utilized as new resources foods.

Candida shehatae xyl1 gene and Pichia stipitis xyl2 gene were amplified by PCR and the xyl1 and xyl2 were both placed under the promoter GAL of vector pYES2 to produce the recombinant expression vector pYES2-P12. Subsequently the pYES2-P12 vector was transformed into S. cerevisiae YS58 by LiAc to produce the recombinant yeast YSS8-12. It was indicate that the recombinant yeast YSS8-12 could converse xylose to ethanol with the xylose consumption rate of 81. 3%.
