ABSTRACT
Clinical data of 12 patients with pernicious placenta previa admitted in our hospital from October 2015 to July 2016 were retrospectively reviewed.Bilateral internal ilia artery balloons were placed percutaneously before cesarean section.After cesarean delivery normal saline was applied to fill the balloon for temporary occlusion of bilateral iliac arteries,then placental separation and hysterorrhaphy were performed.The average volume of bleeding during cesarean section was 1 146 ml.There were no hysterectomy,pelvic organ necrosis,lower limb artery thromosis and other complications.The application of temporary internal iliac artery balloon occlusion can significantly reduce the intraoperative bleeding in cesarean section for patients with pernicious placenta previa.It provides a clear operational field for obstetricians to perform the placental separation and hysterorrhaphy,facilitating the uterine reservation.
ABSTRACT
To explore the therapeutic value of topical timolol maleate eye drops for infantile superficial hemangiomas.From March 2013 to May 2014,a total of 98 patients of infantile superficial hemangiomas during proliferative phase were divided into treatment (n =68) and control (n =30) groups.Topical smearing of timolol maleate eye drops was applied on tumor with a wet cotton swab.The effective rate of tumor shrinkage and the rate of color improvement for treatment group were better than those for control group (88％ vs.10％ ; 90％ vs.10％,both P ＜ 0.05).And the differences had statistical significance.Topical application of timolol maleate eye drops is both safe and efficacious for infantile superficial hemangiomas during proliferative phase.
ABSTRACT
Objective To observe the effectiveness and economic evaluation of appropriate technique for hypertension in community.Methods Systematic management,behavioral intervention and drug intervention were promoted for a period of 2 years in the community and the related index changes were observed after 2 years.Results After promoting appropriate technique,the hypertension knowledge,skill level in medical staff were improved (P ＜ 0.01).The treatment rate,control rate of hypertension were higher than 2 years ago (P ＜ 0.01).The average monthly cost of hypertensive patients was reduced(P ＜ 0.05).Conclusion It is effective to promote appropriate technique of hypertension in community.
ABSTRACT
Objective To investigate the vascular protective effect of pretreatment with candesartan on cerebral ischemia in rats.Methods Forty-eight male Sprague Dawley rats were randomly divided into sham operation,ischemia-reperfusion,low-dose candesartan group was randomly redivided into reperfusion 24 h and 72 h subgroups (n = 6).A model of middle cerebral artery occlusion was induced by intraluminal suture method after 4 weeks of drug gavage.Blood pressure was measured preoperatively.The neurological scores were performed after 24 and 72 hours of reperfusion.Then the rats were decapitated and the brains were removed.The infarct volume was measured using 2,3,5-triphenyltetrazolium chloride staining.The expression of vascular endothelial growth factor (VEGF) protein in ischemic regions was detected by immunohistochemical staining and Western blot analysis.Results The neurological scores of the low-dose and high-dose candesartan groups at 24 and 72 hours after reperfusion were significantly better than those of the ischemia-reperfusion group (P = 0.008and 0.001,respectively),and the infarct volume was reduced significantly (P=0.010 and 0.000,respectively).At the second week after medication,the blood pressure was decreased significantly in the high-dose candesartan group,and there was no significant antihypertensive effect in the low-dose candesartan group.The positive expression of VEGF mainly distributed in the vascular endothelial cells around the infarcts.Its expression was further upregulated with the time.It reached the peak after 72-hour reperfusion.The result of Western blot analysis was consistent with that of immunohistochemical staining.Conclusions Candesartan may reduce the infarct volume by upregulating the expression of VEGF in the ischemic region and improve the neurological score.
