Objective: To observe the influencing factors for efficiency of liposome-mediated transfection into human umbilical vein endothelial cell(HUVEC). Methods: Transferring HUVECs by distinct conditions,such as ratios of liposome and plasmid,densities of per well and different times of incubation,and transfection rates were observed and calculated by fluorescent microscope and flow cytometry. Results:⑴ When density of per well exceeded 2?l04 and times exceeded 4 hours,liposome-mediated transfection efficiency of endothelial cells decreased. ⑵With adding plasmid quality, transfection rates increased;while plasmid quality exceeded 1.0 ?g,in condition of 2?l04 per well and liposome volume 2 ?l, transfection efficiency reached the peak level. ⑶With adding liposome volume, transfection rates increased;while liposome volume was 8 ?l,in condition of 2?104 per well and plasmid quality 1 ?g, transfection efficiency was depressed.When ratios of liposome and plasmid were 1:6～1:8,the optimal transfection efficiency was 18.62%. Conclusion: Using optimal transfection parameter,we obtained the optimal transfection efficiency .

MicroRNA(miRNA) is involved in virtually all biologic processes, including cellular proliferation, apoptosis, and differentiation. Thus, miRNA deregulation often results in impaired cellular function and disease development, so miRNAs have potential therapeutic relevance. The elucidation of these processes regulated by miRNAs and the identification of novel miRNA targets in the pathogenesis of hypertension is a highly valuable and exciting strategy that may eventually led to the development of novel treatment approaches for hypertension. Several mechanisms have been implicated in the pathogenesis of hypertension: overactivation of therenin-angiotensin-aldosterone system (RAAS), dysfunction of the vascular endothelium, damnification of vascular smooth muscle. To maintain and restore target organ expression of miRNA stable may be a new strategy for treatment of hypertension. The article reviews pathogenesis of miRNA and hypertension, researches of miRNAs as biomarker and therapeutic target, discusses advances in miRNA-based approaches that may be important in treating hypertension.

OBJECTIVE:To provide a reference for innovative drugs to enter the health insurance directory smoothly and pro-mote the rapid development of pharmaceutical industry in China. METHODS:Based on related policy study of foreign and domes-tic innovative drugs entering the health insurance directory,the policy barriers of innovative drugs entering the health insurance di-rectory were analyzed and the countermeasures were put forward. RESULTS & CONCLUSIONS:In China,the foundation of drug selection was not objective enough;the review results were so vulnerable to subjective views because of the experts selection mech-anism;the health insurance directory deletion mechanism was deficient;the waiting time for innovative drugs entering the health in-surance directory was too long;innovative drugs negotiation mechanism was imperfect,etc. It is recommended that forcibly requir-ing pharmaceutical companies should provid the related data about pharmacoeconomic evaluation;the independence and pluralism of the expert group should be enhanced;drugs in the health insurance directory should be secondarily evaluated regularly;the inno-vative drugs should be given the green channel;innovative drug price negotiation rules should be unified to promote drug informa-tion sharing.

Objective To study the relation between copper,copper-zinc ratio in blood and blood-fat only in the copper intake lower than the normal acceptable daily intake,and to provide a unified dosage evidence for copper multi-ways exposure.Methods Forty-two SD rats were divided into 7 groups randomly.The rats in one group among them as the normal control group were fed on the normal fodder and water,the other 6 groups were fed on special fodder without copper and deionized water and i.g.copper gluconate at doses of 0ADI(the acceptable daily intake of rat),1/625ADI(0.000 128 mg/ml),1/125ADI(0.000 64 mg/ml),1/25ADI(0.003 2 mg/ml),1/5ADI(0.016 mg/ml) and ADI(0.8 mg/ml),for 30 days.The activity of ceruloplasmin(CP),the content of copper,zinc in the blood and the level of total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL) and low density-lipoprotein(LDL) were determined.Results In the case of copper intake lower than the normal acceptable daily intake,the activity of CP in the blood of all treated rats were lower than the normal level(P

Therapeutic effects and causes of operative success were analyzed. Results The therapeutic efficacy in endoscopic surgery group was significantly superior to that in the control group ( P

ObjectiveToinvestigatetheclinicalfeatures,riskfactorsforbleedingandtreatment outcomes in moyamoya disease patients w ith intracranial aneurysms. Methods The clinical symptoms, location and size of aneurysm, treatment and the long-term folow-up results of the moyamoya disease patients w ith intracranial aneurysms w ere analyzed retrospectively. Results A total of 34 moyamoya disease patients w ith intracranial aneurysms (35 aneurysms) w ere enrol ed, including 22 (64.7%) in the intracranial hemorrhage group and 12 ( 35.3%) in the non-intracranial hemorrhage group. Of the 35 intracranial aneurysms, 23 (main artery type 11, peripheral artery type 12) w ere in the intracranial hemorrhage group and 12 (main artery type 11, peripheral artery type 1) w ere in the non-intracranial hemorrhage group. There w ere 29 smal aneurysms and 6 medium aneurysms (al w ere patients w ith hemorrhagic moyamoya disease). The aneurysms w ere mainly peripheral arterial type in the intracranial hemorrhage group, and the aneurysms w ere mainly artery type in the non-intracranial hemorrhage group. There w as significant difference in aneurysm typing betw een the tw o groups ( P= 0.013 ). Tw o patients did not perform encephalo-duro-arterio-synangiosis (EDAS) in the intracranial hemorrhage group, other patients and those of the non-intracranial hemorrhage group performed EDAS. Angiographical reexamination revealed that 3 patients w ith peripheral aneurysm disappeared, and 1 aneurysm recurred after aneurysm embolization, and the remaining aneurysms did not have any change. Long-term fol ow-up show ed that 1 patient died of sudden cerebral hemorrhage at 1 year after procedure in the intracranial hemorrhage group, and the others did not have ischemic or hemorrhagic stroke. The modified Rankin scale scores w ere improved in 21 patients. Conclusions There are differences in moyamoya disease patients w ith intracranial aneurysm typing w ith different clinical manifestations. Moyamoya disease patients w ith intracranial aneurysms are mostly smal aneurysms and they can not temporarily be treated directly and can perform EDAS directly. Intracranial aneurysms after procedure may remain long-term stability, and some peripheral aneurysms may disappear.
