Intimal areas were measured using morphometric analysis of perfusion-fixed vein graft specimens, and intimal thickness was calculated using circumferential measurements. The SMC proliferation was studied by the immunohistochemical detection of proliferating cell nuclear antigen. Expression of MMP-2、MMP-9 mRNA in vein grafts and unoperated control Vein grafts was detected by reverse transcription polymerase chain reaction. Substrate gel zymography was used to determine the proteolytic activity.

AR was tagged for elimination via the UPP by DHT-PROTAC, and this could be blocked by proteasome inhibitors.

使用蛋白酶体抑制剂能减少雄激素降解，证明该嵌合分子通过激活泛素蛋白酶体途径易化降解靶蛋白。

The Simpson and Shannon-Weiner indices of aquatic plant diversity were both significantly positively correlated with catalase, protease and invertase, and negatively correlated with urase, soil organic matter and total nitrogen. Similarly, soil organic matter and total nitrogen were negatively correlated with catalase, protease and invertase but positively correlated with urase.

植物α多样性指数(辛普森、香浓-维纳指数)与湿地土壤有机质、全氮含量呈负相关，与土壤过氧化氢酶、蛋白酶、蔗糖酶活性呈正相关，与脲酶活性呈负相关；土壤有机质、全氮含量与过氧化氢酶、蛋白酶、蔗糖酶活性呈一致负相关，与脲酶活性则成正相关。

The synthetic evaluation of soil biology---biological fertility indices were (0-40cm depth of soil, same below): 0.635 →0.074 →0.014 . Significant degradation of soil texture, obvious decrease of soil organic matter , and increase of the availability of aluminum were found in the degradation series. Along with the fast vanishment of vegetation, the number of soil microbe and enzymatic activities decreased drastically, among which protease activity degraded most markedly and was only detected in soil of ZR.

土壤物理性质中，土壤质地发生了根本性退化；土壤化学性质中，随着植被的退化，有机质含量的减少和Al的有效性的提高都很明显；土壤微生物和酶活性中，各类微生物的数量退化非常显著，其活性也随植被的退化急剧减弱，酶活性也大大降低，以蛋白酶活性降低最为显著，大部分退化地段未检测出蛋白酶的活性。

Normally MMPs exist as zymogen in the inactive form and their modulations are controlled at multi-levels.

通常情况下，MMPs受多层次的调控并以酶原的形式存在，激活过程受丝氨酸蛋白酶或纤维蛋白酶的介导，也可以自主催化激活，此外还受其特异性组织抑制剂的调节。

This process is the result of the imbalance between matrix metalloproteinases zymogen activations and interaction of the active forms with specific tissue inhibitors of metalloproteinases.

本实验以大鼠为模型旨在研究急性胰腺炎中基质金属蛋白酶-2(MMP-2)与基质金属蛋白酶特异组织抑制物-2(TIMP-2)在胰腺组织中的表达，探讨其与急性胰腺炎时器官损伤程度的相关性。

In order to extract insoluble dietary fiber from coconut residue,monofactorial tests were carried out based on component analysis of coconut residue to determine the appropriate levels of factors influencing proteolysis and adipolysis,orthogonal test was accomplished to optimize technological conditions of one-step zymohydrolysis and the product's function was determined too.

为提取椰子渣不溶性膳食纤维(insoluble dietary fiber，IDF)，在测定椰子渣化学组成后经蛋白酶和脂肪酶分步酶解的单因素试验初步确定影响酶解各因素的适宜水平，在此基础上采用正交试验优化蛋白酶和脂肪酶一步酶解制备IDF的工艺条件，并测定产品的性能。

In order to understand the mechanism of the insecticidal fraction F3-28 from the extract of Periploca sepium bark. The effect of F3-28 on the activities of protease, trypsin-like, chymotrypsin-like, lipase and amylase of the 5th larvae of Mythimna separata and Agrotis ypsilon were studied.
