Thrombus is a major factor leading to cardiovascular diseases such as myocardial infarction and stroke. Although fibrinolytic anti-thrombotic drugs have been widely used in clinical practice, they are still limited by narrow therapeutic windows, short half-lives, susceptibility to inactivation, and abnormal bleeding caused by non-targeting. Therefore, it is crucial to effectively deliver thrombolytic agents to the site of thrombus with minimal adverse effects. Based on the long blood circulation and excellent drug-loading properties of human serum albumin (HSA), we employed genetic engineering techniques to insert a functional peptide (P-selectin binding peptide, PBP) which can target the thrombus site to the N-terminus of HSA. The fusion protein was expressed using Pichia pastoris and purified by Ni-chelating affinity chromatography. After being loaded with gold nanoparticles (Au NPs), the fusion protein formed homogeneous and stable nanoparticles (named as PBP-HSA@Au) with a diameter of 17.7 ± 1.0 nm and a zeta potential of -11.3 ± 0.2 mV. Cytotoxicity and hemolysis tests demonstrated the superb biocompatibility of PBP-HSA@Au. Platelet-targeting experiments confirmed the thrombus-targeting ability conferred by the introduction of PBP into PBP-HSA@Au. Upon near-infrared ray (NIR) irradiation, PBP-HSA@Au rapidly converted light energy into heat, thereby disrupting fibrinogen and exhibiting outstanding thrombolytic efficacy. The designed HSA fusion protein delivery system provides a precise, rapid, and drug-free treatment strategy for thrombus therapy. This system is characterized by its simple design, high biocompatibility, and strong clinical applicability. All animal experiments involved in this study were carried out under the protocols approved by the Animal Experiment Ethics Committee of Jiangnan University [JN. No20230915S0301015(423)].

ObjectiveTo explore the effect of blocking the JAK/STAT signal pathway on the activity of Caspase-3 in the synovial tissue of rheumatoid arthritis rats.MethodsFifty rat models of collageninduced arthritis,which had arthritis index more than 2 were divided into the model group,the low dosage of AG490 group,the medium dosage of AG490 group and high dosage of AG490 group.Inaddition,6 rats were treated as normal control group.Normal saline,AG490 1,5,10 mg·kg-1 ·d-1 were given by intraperitoneal injection.Then the volume claws and pathologic scores of the rat models were recorded and the activity of Caspase-3 in the synovial tissue were compared.The results were analyzed by one-way ANOVA and LSD-t or Tamhane's T2 test.ResultsThe arthritis of the CIA models progressed fast,the volume of the claws and the pathological score of them were significantly higher than those of the control group.At the same time,no Caspase-3 positive express could be detected in the control group,whilethe model group had slightly increased expression.After different dosages of AG490 were applied,the swollen of joints was significantly improved compared with the model group.The histopathological score of the medium AG490 dosage of group and high dosage group(2.7±0.8,1.8+0.9) were remarkably decreased than those of the model group(4.3+1.2),the differences were statistically significant (P＜0.01).In addition,the Caspase-3 expression in the low,medium and high AG490 dosage group ( 1.90±0.15,3.13±0.33,3.56+0.34) was significantly higher than that of the model group(1.48±0.18)(P＜0.05 or P＜0.01 ).ConclusionBlocking JAK/STAT signal pathway can increase the activity of Caspase-3,reduce the excessive proliferation of synovial tissue,and improve arthritis symptoms.

A strain with relative higher phytase-producing ability, Aspergillus fumigatus WY-2 was screened from soil. The optimal pH and temperature for activity of the phytase from A.fumigatus WY-2 were 5.5 and 55 ℃, respectively. The gene encoding the phytase was amplified from genomic DNA of the strain by PCR, and a 1.5 kb DNA fragment was obtained and then was cloned into vector pMD18-T. The sequencing analysis revealed that the DNA fragment contained a whole open reading frame (ORF) of phytase gene. The phytase gene was 1459 bp in length included with a 61 bp intron and encoded 465 amino acids. A signal peptide encoding 26 amino acids was found at 5′end of the gene. There were 7 potential glycosylation sites in the phytase. The present phytase showed 91% identity in nucleotide sequence and 91% identity in deduced amino acids sequence to the previously reported A.fumigatus ATCC34625 phytase.
