ABSTRACT

Proprotein Convertase Subtilisin/Kexin 9 (PCSK9) inhibitor has become a new drug for the treatment of hypercholesterolemia and atherosclerotic cardiovascular disease. Recent studies have shown that the mechanism of PCSK9 in atherosclerotic cardiovascular disease is very complex, which is closely related to the increase of plasma low-density lipoprotein cholesterol level, apoptosis, autophagy, inflammation, foam cell formation and vascular smooth muscle cell calcification, which will help us better understand the " multiple effects" of PCSK9 inhibitors. This review aims to analyze the research status of PCSK9 in molecular structure, cell function and cardiovascular disease treatment, which will further consolidate the success of new treatment strategies for atherosclerosis.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effect of the autoantibody against the β3-adrenoceptor on rats with experimental heart failure.</p><p><b>METHOD</b>The peptide corresponding to the sequence of β3 adrenoceptor was synthesized to actively immunize the rats, ELISA was used to detect the serum level of autoantibody against the β3-adrenoceptor (β3AA). Total IgGs were extracted from the serum containing β3AA in immunized rats. Aortic banding surgery was used to establish the heart failure model in male Wistar rats and rats were divided into the sham group (n = 8), heart failure group(n = 8),β3AA-immunized heart failure group (HF+β3AA, n = 8) and corresponding negative IgG-immunized heart failure group (HF+ IgG, n = 8).In 6 weeks and 8 weeks after aortic banding surgery, the serum levels of NT-pro brain natriuretic peptide (NT-proBNP) were assayed with ELISA assay and cardiac function was assessed by echocardiography.</p><p><b>RESULTS</b>β3AA was used to immunize rat with heart failure, the serum level of β3AA was stable at 50 days post immunization. At 8 weeks after aortic banding surgery, heart failure group showed significantly increased LVEDD [(6.92 ± 0.22) mm vs.(5.62 ± 0.19) mm, P < 0.001], LVESD [(4.63 ± 0.23) mm vs.(3.50 ± 0.20) mm, P < 0.01] and IVS [(2.44 ± 0.06) mm vs.(2.28 ± 0.05) mm, P < 0.05], and decreased LVEF[(62.07 ± 3.99)% vs.(79.63 ± 3.02)%, P < 0.01] and LVFS [(31.46 ± 3.22)% vs.(43.65 ± 2.68) %, P < 0.05] compared with the sham group.HF+β3AA IgG group showed decreased LVEDD [(6.07 ± 0.30) mm vs.(6.92 ± 0.24) mm, P < 0.05] and LVESD [(3.92 ± 0.22) mm vs.(4.68 ± 0.23) mm, P < 0.05], and higher LVEF [(70.29 ± 1.78)% vs.(61.95 ± 3.03)%, P < 0.05] and LVFS [(38.08 ± 2.32)% vs.(30.50 ± 1.82)%, P < 0.05] compared to the HF+ IgG group.In addition, compared with the HF+ IgG group, HF+β3AA IgG group showed decreased serum levels of NT-proBNP [(196.43 ± 6.56) pg/ml vs.(242.13 ± 7.86) pg/ml, P < 0.01].</p><p><b>CONCLUSION</b>Our results demonstrate that β3AA can improve cardiac function and reduce the serum levels of NT-proBNP in rat with heart failure.</p>

ABSTRACT

Objective To compare the curative effect of Epalrestat and mecobalamine .Methods Epalrestat to treat 48 pa-tionts in DPN and mecobalamine to treat 42,measuring blood sugar ,blood pressure, blood fat and body mass index (BMI) prior and post treatment ,and measuring the MCV and SCV of nervus medianus ,nervus peronaeus connunis and nervus tibialis with EMG .Re-sults The symptom of the two sets have all been improved after the treatment ,and the effective power of Epalrestat and mecobalamine is 92.7% and 80.5% respectively.mean while there is improvement in MCV and SCV of nervus medianus ,nervus peronaeus connunis and nervus tibialis,and is more obvious in the set of Epalrestat ( P <0.01).In the whole process of the treat of the two sets ,no one appear to have adverse reactions .Conclusions Epalrestat has significant curative effect with less adverse reactions , and deserves to be spreaded in clinic.

ABSTRACT

The paper presents a detailed review of British pharmaceutical standards including British Pharma-copoeia, European Pharmacopoeia, British Approved Names, Reference Standards and Non-Statutory Pharmaceutical Standards. British pharmaceutical standards are established by the British Pharmacopoeia Commission, Expert Advi-sory Groups, Panels of Experts and Working Parties, British Pharmacopoeia Commission Secretariat, British Pharma-copoeia Laboratory, and standard-setting procedures are clear and definite. British Pharmacopoeia standards are le-gally binding, and pharmaceutical products sold in the United Kingdom must comply with pharmacopoeia require-ments. British pharmaceutical standards can serve as an important reference for reforms to China’s pharmaceutical standards, including the scientific management of pharmaceutical standards, the improvement of organizational frame-works in the establishment pharmaceutical standards, the promptness of amendments to pharmacopoeia, and the uni-versality of international exchanges.
