Objective To investigate the differences in clinical efficacy and safety between thrombolysis followed PCI (percutaneous coronary intervention) and primary PCI in patients with acute STEMI (ST elevation myocardial infarction). Methods A total of 215 STEMI patients who visit our clinic within 12 h since onset of their symptoms from May 2013 to January 2015 were enrolled. All eligible patients were divided into Early PCI group(n=68) and pPCI group (n=147) based on whether or not they received injection of recombinant human prourokinase thrombolytic therapy before their visit. Immediate TIMI (Thrombolysis In Myocardial Infarction) flow grade of infarct-related artery (IRA) before and after PCI treatment, post?operative CTFC (Corrected TIMI Frame Count) and TMPG (TIMI myocardial perfusion grade) were compared between these two groups. The incidence of bleeding during hospital stay , left ventricular function at 6 month after intervention and major adverse cardiac events (MACE) were all observed. Rusults There is no obvious difference between the baseline of two groups. Before PCI, the proportion of TIMI grade 2-3 was higher in Early PCI group (77.9%vs 20.4%,P<0.05)than that in pPCI group;but there was no significant difference in the proportion of TIMI grade 2-3 between these two groups after PCI (P>0.05). CTFC and peak value of serum CK-MB were lower [(27.7 ± 5.0) vs (32.6 ± 7.1), P<0.05;(225.8 ± 108.3) U/L vs (283.4 ± 110.6) U/L, P<0.05] and rate of TMPG 3 is higher (82.4%vs 68.7%, P<0.05)in Early PCI group than those in pPCI group. No significant difference was found in the incidence of bleeding and MACE during hospital stay and Left ventric?ular function at 6 months after operation between these two groups. By contrast, LVEFs were higher while LVEDds (LVED diameter) were lower after 3 and 6 months of the intervention compared to those before intervention in both groups (P <0.05). Conclusion It is a safe and effective reperfusion strategy for STEMI patients to receive rhPro-UK thrombolytic thera?py followed early PCI as an alternative way to those who failed to receive pPCI on time. It didn′t increase the occurrence of bleeding complications and MACE, and at the same time it presented the same benefit in improving recent cardiac function as pPCI did.

Aim To investigate the effect of Jinlida on cholesterol-related genes in skeletal muscle in fat-in-duced insulin resistance ApoE-/ - mice. Methods Ten male C57 BL/6 J mice were selected as normal group ( NF );50 male ApoE-/ - mice with a high-fat feeding after 16 weeks ( HF) were divided into model group, rosiglitazone ( LGLT ) , Jinlida low dose group ( JLDL, 0. 95 g · kg-1 · d-1 ) , Jinlida medium dose group ( JLDM, 1. 9 g·kg-1 ·d-1 ) , Jinlida high dose group (JLDH, 3. 8 g·kg-1·d-1), which were per-formed intragastric administration for 8 weeks. Oil red O staining of mouse skeletal muscle was used for fat ac-cumulation. Insulin receptor ( INSR) , insulin receptor body substrate-1 ( IRS-1 ) , low-density lipoprotein re-ceptor ( LDLR ) , cholesterol sensor ( SCAP ) mRNA and protein expression in mouse skeletal muscle were measured by quantitative reverse transcription PCR ( RT-PCR ) and Western blot. Results Compared with NF group, fasting blood glucose ( FBG) , choles-terol ( TC ) , triglyceride ( TG ) and low density lipo-protein cholesterol ( LDL-C ) of HF mice were signifi-cantly elevated, while high-density lipoprotein ( HDL-C ) significantly decreased ( P < 0. 05 ) . Compared with HF group, Jinlida group could reduce to varying degrees FBG, TC, TG and LDL-C in mice, and in-crease HDL-C ( P <0. 05 ) . Jinlida could downgrade fasting serum insulin ( FINS ) level, and improve the insulin sensitive index ( ISI ) ( P < 0. 05 ) . Jinlida could obviously improve skeletal muscle fat accumula-tion of mice. Compared with NF group, skeletal mus-cle INSR, IRS-1, LDLR mRNA and protein levels of HF group were significantly decreased ( P <0. 05 ) , while SCAP mRNA and protein level increased signifi-cantly (P<0. 05). Compared with HF group, Jinlida could increase to varying degrees INSR, IRS-1, LDLR mRNA and protein levels ( P < 0. 05 ) , and lower SCAP mRNA and protein levels ( P<0. 05 ) . Conclu-sion Jinlida can alleviate fat-induced insulin resist-ance in ApoE-/ - mice through regulation of cholester-ol-related gene expression.

In order to identify Peucedani Radix, Peucedani Decursivi Radix and their adulterants, the internal transcribed spacer 2 (ITS2) regions of Peucedani Radix, Peucedani Decursivi Radix and their adulterants were amplified and bidirectionally sequenced based on the Principles for Molecular Identification of Traditional Chinese Materia Medica Using DNA Barcoding, which has been promulgated by Chinese Pharmacopoeia Commission. Sequences were analyzed and assembled by Codon Code Aligner V3. 7.1. The relevant data were analyzed by MEGA 5. 0. Species identification analyses were performed by using the nearest distance methods and neighbor-joining (NJ) methods. The result showed that the ITS2 sequence lengths of Peucedani Radix were 229-230 bp and the average intra-specific genetic distances were 0.005. The ITS2 sequence lengths of Peucedani Decursivi Radix were 227 bp and the sequences contained no variation site. The average inter-specific K2P genetic distance of Peucedani Radix, Peucedani Decursivi Radix and their adulterants species were 0.044 and 0.065 respectively. The minimum inter-specific divergence is larger than the maximum intra-specific divergence of Peucedani Decursivi Radix. The nearest distance methods and NJ trees results indicated that Peucedani Radix, Peucedani Decursivi Radix and their adulterants species could be identification clearly. The ITS2 regions can stably and accurately distinguish Peucedani Radix, Peucedani Decursivi Radix and their adulterants.
