AIM: To study the effect of Salvia miltiorrhiza injection on rat atherosclerosis (AS), and elucidate the possible mechanism. METHODS: Wistar rats were fed with fat-rich diet and high dose of vitamin D_3 to induce AS, then treated with Salvia miltiorrhiza injection. Concentrations of triglyceride (TG) and total cholesterol (TC) in serum were measured by automatic serum biochemical assay. The level of ICAM-1 protein and mRNA were determined by Western blot and RT-PCR. RESULTS: Compared with the AS model group, the levels of TG and TC in serum were significantly lower in Salvia miltiorrhiza injection group (P

Background Posterior capsular opacification (PCO)affects the pseudoaccommodation of 1CU accommodative intraocular lens (1CU AIOL).At present,few studies on the effect of PCO and Nd∶ YAG laser capsulotomy on intraocular shifting of 1CU AIOL are published.Objective The present study was to evaluate the effect of PCO and Nd∶YAG laser capsulotomy on the shifting of 1CU AIOL.Methods A respective serial caseobservational study was designed.Written informed consent was obtained from each patient prior to this study.Twentyfour eyes of 20 patients with PCO after phacoemulsification and implantation of 1CU AIOL were included in this study.Ocular examination was performed 3 months after IOL implantation,1 day before Nd:YAG laser capsulotomy and 3 months after Nd∶YAG laser capsulotomy to evaluate the distance corrected near visual acuity(DCNVA).The difference in the anterior chamber depths before and after administering 1% pilocarpine topical eye drops was measured with the IOLMaster to determine the intraocular shifts of the IOL.The extent of IOL shifting was compared among 3 time points to assess the factors influencing IOL accommodation after 1CU AIOL implantation.Results The shifting amplitude of 1CU AIOL was(0.44±0.21)mm 3 months after implantation of 1CU AIOL,(0.27±0.11)mm 1 day before Nd ∶ YAG laser capsulotomy,and (0.34±0.10) mm 3 months after Nd ∶ YAG laser capsulotomy,showing a significant difference among them(F=7.180,P=0.001).The shifting amplitude of 1CU AIOL significantly declined 1 day before Nd∶YAG laser capsulotomy in comparison with 3 months after implantation of 1 CU AIOL(P =0.006).The shifting amplitude 3 months after Nd∶YAG laser capsulotomy increased slightly in comparison with 1 day before Nd∶YAG laser capsulotomy(P=0.059).DCNVA was(3.1±0.9)J 3 months after implantation of 1CU AIOL,(6.2±0.8) J 1 day before Nd ∶ YAG laser capsulotomy and(3.4±0.7) J 3 months after Nd ∶ YAG laser capsulotomy,with a significant difference among them (F =110.270,P =0.000).DCNVA was lower 1 day before Nd∶ YAG laser capsulotomy than 3 months after implantation of 1CU AIOL(P<0.05).However,DCNVA was higher 3 months after Nd∶YAG laser capsulotomy than that of 1 day before Nd∶YAG laser capsulotomy (P<0.05).There was no significant correlations between DCNVA and IOL movement 3 months after IOL implantation,1 day before Nd∶ YAG laser capsulotomy and 3 months after Nd ∶ YAG laser capsulotomy (r1 =-0.150,P1 =0.486,r2 =-0.320,P2 =0.122,r3 =-0.100,P3 =0.633).Conclusions The shifting amplitude of 1CU AIOL markedly declines due to PCO.No clinically significant influence of Nd ∶ YAG laser capsulotomy on the shifting amplitude of 1 CU AIOL is found.DCNVA can improve after Nd∶YAG laser capsulotomy.Multiple inter-related factors concerning pseudophakic accommodation may influence DCNVA.

The volatile oils of endophyte isolates R1 (Acremonium sp.) and R2 (Acremonium sp.) from Aqui-laria sinensis were extracted by solvent method. Twenty and sixteen ingredients were identified from the volatile oils of R1 and R2 by GC-MS, respectively. Fatty acids, such as oleic acid, linoleic acid, hexa-decanoic acid etc., were the main components, whereas terpenoids like 1,8-cineole, zingiberene, ar-curcumene were also found in both oils. It’s the first report about the volatile oil constituents of endophyte isolates from A. sinensis.
8. Research progress on non-injection administration systems of paclitaxel
Chinese Traditional and Herbal Drugs 2019;50(17):4020-4030
Paclitaxel (PTX) is a complex secondary metabolite isolated from Taxus brevifolia, which widely used as chemotherapentic agent with a broad spectrum of actinity against cancer in the world. Its water solubility was poor and oral bioavailability was low. Cremophor-EL was used in traditional PTX injections to improve the solubility of PTX, and resulted in several adverse side effects such as severe hypersensitivity. Pre-desensitization treatment was needed before clinical use. Recently, a variety of non-injection drug delivery systems (DDS) of PTX have been developed. In this paper, the research progress of non-parenteral PTX was reviewed, including oral administration systems, vaginal administration systems, transdermal DDS, implantable DDS, transdermal DDS, intranasal administration and inhalation DDS, so as to provide references for future study and clinical applications.
