Objective To discuss the relationship between pulse pressure and blood uric acid and the effect of simvastatin on pulse pressure and blood uric acid in aged primary hypertension (PH) patients with normal cholesterol.Methods Eighty-five patients with PH were divided into two groups randomly,routine group (using drugs only to lower blood pressure) and simvastatin group (simvastatin was added).Six months later,blood uric acid and pulse pressure was measured again.Results With the development of hypertension,there was statistical difference on pulse pressure and blood uric acid between hypertension grade 3 and grade 1 or grade 2 (P < 0.05).With the increase of pulse pressure,the trend of blood uric acid increase was distinct,and blood uric acid level was positively related with pulse pressure by correlation analyses(r = 0.87,P< 0.05).The pulse pressure and blood uric acid was decreased after treatment compared with that before treatment in simvastatin group (P < 0.05),but there was no significant difference before and dter treatment in routine group (P >0.05).There was significant difference after treatment between two groups (P< 0.05).Conclusions With the increasing of pulse pressure,there is a significant raise in blood uric acid.Blood uric acid is positively related with pulse pressure by correlation analyses.Simvastatin is a drug used to lower cholesterol,and it could also be used to reduce pulse pressure and blood uric acid in aged PH patients with normal cholesterol.

Objective To investigate the analgesic effect of epidural labor analgesia with contin-uous background infusion and its impact on obstetric outcome.Methods This was a retrospective co-hort study.In the two months of march 2014 and march 201 5,503 nulliparas women who had re-ceived epidural analgesia for labor were enrolled and assigned to two different study groups according to their analgesic protocol.Two hundred and fifty-eight nulliparas in group C received only patient-controlled analgesia while two hundred and forty-five nulliparas in group P received patient-controlled analgesia with continuous background infusion.The basic and perinatal data of all enrolled nulliparas women were collected and analyzed to compare the analgesic effect and the impact on obstetric risk of two different analgesic protocol.Results The NRS pain score during the second labor stage was lower in group P [3 (3-4)scores vs.5 (4-5)scores](P <0.001).The second stage prolonged [50 (29-82) min vs.38 (24-62)min](P =0.001)and intrapartum hemorrhage increased [200 (100-250)ml vs. 1 50 (100-200)ml](P =0.003)in group P.There were no significant differences between the two groups with regard to the delivery mode (P =0.656)and the morbidity of postpartum hemorrhage (9.8% vs.10.9%,P =0.697).Analgesic protocol with background infusion was not associated with postpartum hemorrhage,instrumental delivery risk and cesarean risk.Conclusion Epidural labor an-algesia with continuous background infusion provided more effective analgesia in nulliparas,without additional obstetric risk.

In order to explore the possibility and feasibility of administering antisense oligodeoxynucleotide to vascular adventia delivering by fibrin tissue adhesive, the authors first observed the physical characteristics of the adhesive, then the blue dye (methylenophin) was dissolved in the adhesive and the color change of the supernate was monitored. The adhesive with antisense oligomer inside was immerged in saline and the optical density (OD) value of the released oligomer was measured by ultraviolet spectrophotometer at different time points, then the in vitro controlled releasing curve was made. The preliminary in vitro test found the adhesive clot in 10 seconds when the two kinds of solution were mixed together, and the surface was membrane like under microscope, the clot inside was silk protein like configuration and was filled up with particle like liquid. The clot was elastic and had some reabsorbable property like that of sponge. The blue dye inside the clot gave a more and more significant dyeing of the supernate with time going. The in vitro releasing curve indicated that most oligomer was released within 72 hours. This implied that the adhesive clot is like a sponge reservoir of drugs, it could elongate the action time of antisense drug at vascular adventia.
