Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and apolipoprotein(Apo) AI were lower in Bai Ku Yao than in Han(P【0.01 for all).The frequency of A and G alleles was 98.00%and 2.00%in Bai Ku Yao,and 95.20%and 4.80%in Han(P【0.01);respectively. The frequency of AA,AG and GG genotypes was 95.99%,4.01%and 0%in Bai Ku Yao,and 91.02%, 8.36%and 0.62%in Han(P【0.01);respectively.There were also significant differences in the genotypic and allelic frequencies between n and the ratio of ApoAI to ApoB in Han Chinese but not in Bai Ku Yao were different between the AA and AG/GG genotypes(P【0.05 for all).The G allele carriers had higher serum HDL-C and higher ApoAI to ApoB ratio than the G allele noncarriers.When serum lipid parameters in Han were analyzed according to sex,the G allele carriers had higher serum HDL and ApoAI levels in males (P【0.05),and lower ApoB level and higher ApoAI to ApoB ratio in females(P【0.05 for all).Multiple linear regression analysis showed that serum HDL-C levels were correlated with genotypes in both ethnic groups(P【0.05 each).Serum lipid parameters were also correlated with sex,age,body massindex,alcohol consumption,cigarette smoking,and blood pressure in both ethnic groups(P【0.05-0.001).Conclusions These results suggest that the PCSK9 E670G polymorphism is mainly associated with some serum lipid parameters in the Han population,both gender show different relations to different serum lipid parameters.The G allele carriers might have higher serum lipid profiles than the G allele noncarriers. ormal LDL-C(≤3.20 mmol/L) and high LDL-C subgroups (】 3.20 mmol/L,P【0.01;respectively) in Bai Ku Yao, and between normal ApoB(≤1.14 g/L) and high ApoB subgroups(】 1.14 g/L,P 【 0.01;respectively) in Han.展开更多

Proprotein convertase subtilisin/kexin type 9 （PCSK9） can increase the level of low density lipoprotein. Therefore, this study assumed that PCSK9 plays important roles in ischemic cerebrovascular disease. The present study established transient focal cerebral ischemia models after 100 minutes of middle cerebral artery occlusion. In situ hybridization demonstrated that PCSK9 mRNA expression increased gradually with prolonged reperfusion time in ischemic cortices. This indicated that transient focal cerebral ischemia upregulated PCSK9 mRNA expression in ischemic cortices.展开更多

In the meanwhile, additional measures aretherefore required (particularly with gene sequencing or change the treatment plan) must beinitiated as early as possible. Genetic testing for clinically challenging cases who do not respond toPCSK9i therapy is very helpful.展开更多

文摘BACKGROUND Familial hypercholesterolemia(FH)is an autosomal dominant disorder that is characterized by severely increased low-density lipoprotein(LDL)cholesterol levels.At the same time,elevated LDL levels accelerated the development of coronary heart disease.Several classes of drugs are currently in use to treat FH.Proprotein convertase subtilisin/kexin type 9 inhibitor(PCSK9i)is novel one of these.CASE SUMMARY This manuscript reports a case of FH that responded modestly after treatment with PCSK9i and statin drugs.Of even more concern is that the patient frequently admitted to the hospital during a 12-year follow-up period.Subsequently,we identified a heterozygous mutation,1448G>A(W483X)of the LDL receptor(LDLR)in this patient.The serum levels of PCSK9(proprotein convertase subtilisin/kexin type 9)in the patient was 71.30±26.66 ng/mL,which is close the average level reported in the literature.This LDLR mutation affects LDLR metabolism or structure,which may make it unsuitable for use of PCSK9i.CONCLUSION Our outcome demonstrates that LDLR-W483X represents a partial loss-of-function LDLR and may contribute to PCSK9i ineffective. In the meanwhile, additional measures aretherefore required (particularly with gene sequencing or change the treatment plan) must beinitiated as early as possible. Genetic testing for clinically challenging cases who do not respond toPCSK9i therapy is very helpful.
文摘动脉粥样硬化(atherosclerosis, AS)是一种复杂的慢性进行性动脉疾病,被视为全球死亡的重要原因。高水平的血浆低密度脂蛋白胆固醇(low density lipoprotein-cholesterol, LDL-C)是AS发生和发展的关键危险因素。血浆中循环的前蛋白转化酶枯草溶菌素9 (proprotein convertase subtilisin/kexin type 9, PCSK9)是一种肝细胞合成的丝氨酸蛋白酶,是低密度脂蛋白受体(low density lipoprotein receptor,LDLR)的关键调节因子,在控制血浆LDL-C水平方面发挥着关键作用,它通过与肝脏LDLR结合,形成PCSK9-LDLR复合物导致LDLR在溶酶体中降解,并减少肝细胞膜表面的LDLR的数量,进而导致血浆LDL-C水平升高。目前,临床常用他汀类降脂药物,如阿托伐他汀调节LDL-C水平,延缓AS,但药物起效慢,单一应用难以达到理想的效果,且会在不同程度上产生不良影响。因此, PCSK9是一种新的降低胆固醇的治疗靶点。本综述旨在阐明调控PCSK9的途径及改善AS的天然化合物的研究现状和潜在的治疗意义,以期为防治AS提供参考。
