Objective To observe the clinical effects and complications of coronary intervention through radial artery and femoral artery.Methods A hundred and sixty patients received coronary intervention treatment or coronary angiogram in the Second Affiliated Hospital of Bengbu Medical College from March 2010 to March 2015 were enrolled in this study.The patients were divided into radial artery puncture group (n =80),who received radial artery puncture and femoral artery puncture group (n =80) who received femoral artery puncture.The general date such as puncture time,intervention success rate,time in bed,postpuncture compression time and complications such as postoperative bleeding,arterial occlusion and postoperative untoward reactions were recorded and compared.Results The intervention success rate of radial artery puncture group was 90.0％ lower than that of femoral artery puncture group (97.5％),with statistically significant differences (P＜0.05).The puncture time,postpuncture compression time,time in bed and hospital stays of radial artery puncture group were significantly shorter than those of femoral artery puncture group (P ＜0.01).As for complications,the incidences of postpuncture bleeding and vagus nerve reflex in radial artery puncture group were significantly lower than that in femoral artery puncture group (P＜0.05).As for postoperative untoward reactions,the incidences of irritable and insomnia,uroschesis,pain caused by puncture,local skin injure,back pain in radial artery puncture group were significantly lower than those in femoral artery puncture group (P＜0.01).Conclusion With the advantages of mini-invasion,such as shorter time in bed and hospital stays,lower complications and untoward reactions rates,coronary intervention through radial artery is worth of clinical application.

Objective To study the efficacy and safety of estradiol and drospirenone tablets (Angeliq)in treatment of menopausal symptoms among postmenopausal Chinese healthy women.Methods Total 244 postmenopausal Chinese healthy women who had moderate to severe hot flushes were randomly assigned for 16 weeks in this randomized multi-center double-blind placebo-controlled study.During the trial.the follow-up visits were conducted at week 4,8,12,16 of treatment and 2 weeks after treatment respectively.Height,weight,vital signs,hot flushes,other relevant menopausal symptoms and vaginal bleeding were observed in each follow-up visit,while the clinical global impression scale Was assessed at 16 weeks as well.Results It showed that hot flushes were reduced significantly more in observation group than that in placebo group ( P＜0.01 ), although both treatments were effective. The absolute values of mean severity index of total hot flushes decreased by - 0. 6± 0. 5 in observation group and - 0. 4 ± 0. 4 in placebo group from baseline respectively, which reached significant difference ( P ＜ 0. 05 ). However, the absolute values of mean severity index of moderate to severe hot flushes decreased by - 0. 6± 0. 8 in observation group and -0. 3± 0.6 in placebo group from baseline respectively, which had no significant difference (P ＞ 0. 05 ).After 16 weeks treatment, it also showed that estradiol and drospirenone had significant better efficacy than placebo on moderate to severe sweating, vaginal dryness and clinical global impression scale (P ＜0. 01 ).During the trial, blood pressure in observation group was stable. The rate of vaginal bleeding in observation group was higher than that in the placebo group, especially during the week 4 to week 8 when 48. 9% (87/178) in observation group and 10. 7% (6/56) in placebo group of patients bled. Although the cumulative amenorrhea rate of observation group was lower than that of placebo group in each cycle (28 days), it increased gradually along with duration of the treatment. The commonest adverse event in observation group was breast tenderness which accounted for 12.0% (22/183 ). The level of serum potassium was in the normal range in observation group mostly. Meanwhile, the other adverse events rate was low. Serious adverse events reported in this trial were assessed as not study drug related or as unlikely study drug related. Conclusion Estradiol and drospirenone tablets which could effectively alleviate menopausal symptoms in postmeuopausal Chinese healthy women is a novel hormone replacement therapy regimen with high safety and efficacy.
