Objective To investigate the correlation between angiotensin converting enzyme(ACE) gene polymorphism and kawasaki disease(KD).Methods A 287 bp Alu fragment in intron 16 of the ACE gene was used as insertion(I)/deletion(D) polymorphism marker. The ACE genotype of 28 children (10 children complicated coronary dilataltion) with KD and 35 healthy controls were detected by polymerase chain reaction (PCR), and ACE concentration in blood serum was measured by ultraviolet-spectrophotometer assay.Results 1.The ACE concentration was significantly higher in KD group than that in healthy control group(P

0.05),but there were significant difference between the two groups from 12 hours to 48 hours after operation(all P

Objective To find out the associated effect of intrauterine infection and interuterine asphyxia to fetal rat′s brain damage,cell apoptosis,and expression of glial fibrillary acidic protein(GFAP).Methods Pregnant rats of gestation 18 days were randomly divided into four groups:1.NS plus sham operation,2.intrauterine infection,3.intrauterine asphyxia,4.intrauterine infection plus intrauterine asphyxia.The fetal rats′ brains were taken out 72 h after different disposal and given HE coloration,immunohistochemistry of TUNEL and GFAP,respectively.Results The level of brain cell edema and tissue disorganization of group intrauterine infection plus intrauterine asphyxia were more serious than those of group intrauterine infection or group intrauterine asphyxia.TUNEL and GFAP had the same results:The number of positive cells in group intrauterine infection plus intrauterine asphyxia more than that in group intrauterine infection,and which in group intrauterine asphyxia more than that in group NS plus sham operation.There was significant difference between the first three groups and the group NS plus sham operation(P=0).There was also significant difference between group intrauterine infection plus intrauterine asphyxia and group intrauterine infection or group intrauterine asphyxia(P=0).Conclusions Both intrauterine infection and intrauterine asphyxia may induce premature rat brain damage,the association of intrauterine infection and intrauterine asphyxia may aggravate the degree of fetal rat brain damage,also increase the number of apoptosis cell and the expression of GFAP.

CDKs proteins are a kind of cell cycle protein-dependent kinases, which serve as important roles in controlling cell division and transcriptional stages. Among them, CDK9, as a key regulator responsible for the transcriptional elongation of cells, drives the development of various malignant cells and is considered as an important target in the field of anti-tumor drug development. However, the CDK family proteins feature high conservativeness and similarity in structure, leading to the poor selectivity and severe side effects for traditional small-molecular CDK9 inhibitors, which has limited their clinical applications. In view of this, there is an urgent need to investigate CDK9 targets through a novel strategy. The PROTAC is an emerging drug discovery strategy that the degrader could specifically recognize the target protein through indirect linkage with ubiquitin ligases and ultimately eliminate the target protein through the ubiquitination degradation system. This paper provides a brief overview of the structure and function of CDK9 protein, its relationship with the poor prognosis of clinical diseases, as well as the currently reported small molecular inhibitors. The latest research progress on the targeted degradation of CDK9 protein based on PROTAC technology is highlighted. Finally, the development prospects of this target protein in this novel technology field are summarized and prospected, aiming to provide a reference for the development of antitumor drugs in this direction.
