Smoking and exposure to second hand smoke are the deadly killer of human health. Tobacco kills more than one million people each year in China. According to 2015 Chinese adult tobacco survey, the number of smokers in China increased by 15 million during five years, from 301 million in 2010 to 316 million in 2015. Smoking addiction is a chronic recurrent disease, and its pathogenesis is associated with the mesolimbic dopamine system. In recent years, domestic and overseas scholars studied the brain function of smoking addicts through resting state functional magnetic resonance imaging (fMRI), and found that the brain functional activity of smoking addicts has changed. fMRI can help us understand the mechanism of tobacco dependence, and provide the evidence of diagnosis, treatment and health management of tobacco dependence. In this paper, the present study situation and the application in the field of the treatment and management of smoking cessation of fMRI in smoking addicts are reviewed.

The sequences of ITS, matK, rbcL and psbA-trnH of 9 Gynostemma species or variety including 38 samples were compared and analyzed by molecular phylogeny method. Hemsleya macrosperma was designated as outgroup. The MP and NJ phylogenetic tree of Gynostemma was built based on ITS sequence, the results of PAUP phylogenetic analysis showed the following results: (1) The eight individuals of G. pentaphyllum var. pentaphyllum were not supported as monophyletic in the strict consensus trees and NJ trees. (2) It is suspected whether G. longipes and G. laxum should be classified as the independent species. (3)The classification of subgenus units of Gynostemma plants is supported.

This study analysed the tissue specific expression of critical genes involved in chlorogenic acid and luteolin biosynthesis, for exploiting the molecular mechanism of components biosynthesis in Lonicera confusa. Expression of PAL, 4CL, C4H, CHS, CHI, FNS and HQT gene families of chlorogenic acid and luteolin biosynthesis-related genes in buds and leaves of L. confusa were analyed by Real-time PCR. Expressions of PAL1, C4H1, 4CL1, CHS1, CHI3 and HQT2 in buds were lower than that in leaves, and expressions of PAL3, 4CL2, CHI2 and FNS2 in buds were higher than that in leaves. The results indicated that that PAL3 and 4CL2 may be associated with accumulation of chlorogenic acid, and the expression patterns of PAL1, CHS1, CHI3 and HQT2 in buds and leaves of L. confusa were different with L. japonica. This study provided some theoretical basis for the further research on genetic mechanism of active components differences in L. confusa and L. japonica.

Background Refractive lens exchange is one of corrective surgeries for high myopic eyes and is concerned in clinic recently. Its clinical value is worthy of consideration. Objective This study was to investigate the efficacy and safety of refractive lens exchange for high myopic eyes. Methods Phacoemulsification and intraocular lens implantation was performed on 124 eyes of 65 patients with high myopia. The mean age of these patients was 51. 4±8. 57 years old,and the preoperative corrected visual acuity was 4. 11±0. 51. The mean spherical equivalent was ( -20. 17±5. 34) D. The mean axial length was (31. 33±2. 08) mm and intraocular lens power 2. 88 D. The follow-up time was 31 months. The uncorrective visual acuity, best corrective visual acuity, the spherical equivalent lens and complications were observed after operation. Written informed consent was obtained prior to the surgery. Results The uncorrective visual acuity improved after the operation in all the eyes. The uncorrective visual acuity was ≥0.5 in 15 eyes(12% ). The best corrected visual acuity improved in 114 eyes (92% ) following the surgery and that of 64 eyes (51. 6% ) was 2s 0. 5. The mean postoperative spherical equivalent was ( -2. 57 ± 1. 76 ) D in the entire follow-up duration. Posterior capsular opacification was found in 58 eyes (46. 7% ) and received laser capsulotomy. Retinal detachment occurred in 4 eyes throughout the follow-up period. Conclusion Refractive lens exchange is an effective and safe method for high myopic eyes. But preoperative fundus examination and long-term postoperative follow-up should be carried out to prevent the complications.
