Percutaneous coronary intervention(PCI) has become one of the most important therapeutic methods for atherosclerotic heart disease(AHD),but the following complications such as stent thrombosis and restenosis af- fected its long-term efficacy.Platelet activation was a key component of thrombosis of during perioperative period PCI.As one of the most effective antiplatelet drugs,clo- pidogrel has been established its important role in preven- ting thrombosis during perioperative period of PCI.After several large-scale clinical trials in recent years.

The purity of 4,4′-dimethoxy-5,6,5′,6′-bis (methylenedioxy)-2′-morpholine methylenebiphenyl-2-methyl formate methanesulfonate (IMH), a new drug for fatty liver treatment, was determined through differential scanning calorimetry (DSC). Analysis of two-factor non repeatability method was performed in the investigation the effects of two factors (heating rate and sample weight) on purity determination. The DSC experimental parameters were optimized as follows: heating rate was 10 ℃·min^-1, temperature range was 150-300 ℃, sample weight was 2.0-4.1 mg, and N₂ flow rate was 80 mL·min^-1. The linear correlation coefficient (r) of this DSC method was 0.999 8. The RSD value (n = 6) of precision was 0.03%. The standard value and uncertainty of the purity results of the multiple batches of IMH drugs were (99.74 ± 0.29)%, (99.91 ± 0.28)%, (99.90 ± 0.28)%, and (99.81 ± 0.28)% with inclusion factor (K) of 2 and confidence probability (P) of 0.95. The results were basically consistent with the results of the mass balance method. The DSC mehod is a simple, rapid and accurate method, and provides a new reference method for determining the purity of IMH drugs, improves the accuracy and reliability of purity determination.

OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

Objective To set a rapid,simple gene diagnosis method for Down syndrome.Methods Three short tandem repeats(D21S11,D21S1270,D21S1437)loci in or near Down syndrome critical region(DSCR) were analyzed and detected by polymerase chain reaction and DNA quantitative analysis in 11 core ancestry.Results There were four types by DNA quantitative analysis to different individuals at a short tandem repeats(STR) locus.In type one,a homozygote of one allelic gene was detected.In type two,a normal heterozygote of two allelic genes was found,the content or two DNA electrophoresis bands was approximately 1∶1.In type three,a Down syndrome patient of two allelic genes was discovered.The quantity of two electrophoresis bands was nearly 2∶1.In type four,the patient showed three DNA electrophoresis bands which the content was approximately 1∶1∶1.Conclusion A rapid gene diagnosis and prenatal diagnosis method for Down syndrome can be used for quantitative analysis of STR polymorphism loci.

AIM: To evaluate the effects of 23G vs 20G pars plana vitrectomy ( PPV ) combined with internal limiting membrane peeling, phacoemulsification and intraocular lens implantation for macular epiretinal membrane with cataract. ·METHODS: Totally 45 eyes of 45 patients with macular epiretinal membrane and cataract were enrolled in this retrospective non-randomized controlled clinical study. All eyes were treated with PPV combined with internal limiting membrane peeling, phacoemulsification and intraocular lens implantation. There were 20 eyes in 23G PPV group, and 25 eyes in 20G PPV group. The best corrected visual acuity ( BCVA ) , intraocular pressure (IOP), counting of corneal endothelial cells ( CEC) and central retinal thickness ( CRT ) were examined before surgery. BCVA results were converted to the logarithm of the minimum angle of resolution ( LogMAR ) visual acuity. All operations were performed by the same doctor. Operation time for vitrectomy and membrane peeling, average ultrasound energy ( AVE) and effective phacoemulsification time ( EPT ) were recorded. BCVA and CRT were observed postoperatively at 30d and 90d, counting of CEC was observed postoperatively at 90d. IOP was observed postoperatively at 1d and 7d. ·RESULTS:The mean operation time for vitrectomy were 12. 57± 1. 35min in 23G group and 17. 30 ± 1. 19min in 20G group. The difference was statistically significant ( t =-12. 488, P<0. 01). There were no statistical significances in operation time for membrane peeling, AVE and EPT between 23G and 20G groups ( t=-0. 68,-1. 186,-0. 737, P=0. 500, 0. 242,0. 465). On 1d after surgery, IOP in 23G group was lower than that in 20G group, the difference was statistically significant (t= -2. 345, P=0. 024). The BCVA and CRT of the two groups both improved after operations. There were no statistically significant differences between two groups in terms of IOP, BCVA, and CRT ( F = 0. 465, 1. 895, 0. 689; P = 0. 499, 0. 176, 0. 411). IOP, BCVA and CRT were significant statistical different in different time-point within each group ( F=291. 245, 103. 06, 665. 402, P<0. 01 ). Different surgical methods of 23G and 20G had interactive effects on IOP with different time points ( F = 13. 245, P<0. 01 ), but different surgeries had no interactive effects on BCVA and CRT with different time points (F=1. 212, 2. 293;P=0. 283, 0. 129). The counting CEC in 23G group was more than that in 20G group postoperatively at 90d, the difference was statistically significant (t=2. 049, P=0. 048). ·CONCLUSION: The 23G PPV combined with internal limiting membrane peeling, phacoemulsification, intraocular lens implantation for macular epiretinal membrane with cataract is effective. Compared with 20G PPV, 23G PPV has advantages in operation time for vitrectomy and counting CEC. But lower IOP is likely in 23G PPV on 1d after surgery
