ABSTRACT
Objective To observe the effects of Shexiang Baoxin pill combined with intracoronary injection of nicorandil on myocardial perfusion and short-term prognosis after primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction. Methods 151 patients with acute myocardial infarction after PPCI were enrolled in this study. Those patients were admitted to our hospital during January 2017 to January 2018. According to the numerical randomization method, 51 patients were selected as routine treatment group (group A), 50 patients with intracoronary injection of nicorandil (group B) and 50 patients received intracoronary injection of nicorandil plus oral Shexiang Baoxin pills (group C). Intra-operative corrected TIMI frame count (cTFC), postoperative TIMI grade 3 blood flow ratio, 2-hour ECG ST segment fallback >50% index, the incidence of major adverse cardiovascular events (MACE) during hospitalization and the incidence of angina and MACE within 3 months after surgery were evaluated. Results cTFC, 2 hours postoperative ECG ST segment fall >50% index in group B and C were better than group A (P<0.05). The results from group C were better than group B. Group C exhibited better results than group B and C in post-operative angina pectoris 3 months after surgery (P<0.05). Conclusion Shexiang Baoxin pills combined with intra-coronary injection of nicorandil can improve myocardial perfusion and short-term prognosis after primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction
ABSTRACT
Objective:To analyze the clinical and chest CT features in a family with interstitial lung disease(ILD), and assess the probable causative gene mutations for the family.Methods:In order to identify the etiology of the proband′s ILD, the pedigree was investigated.The clinical data of five proband′s pedigree members were collected, and the chest HRCT examination was performed on four proband′s pedigree members with respiratory symptoms.The human whole exon sequencing was performed on the proband′s blood samples, then its deleterious effects were assessed.Subsequently, the strong pathogenic mutation was validated by Sanger sequencing.Results:According to the family survey, there were five patients with ILD in the family, including three males and two females.One of them died.The surfactant protein C(SFTPC)gene(exon4, c.342G>T, p.K114N)was found in all four surviving patients.The mutation was considered to be originated from the father of the proband, and the pathogenic mutation was considered, which was not included in the databases and was a noval mutation.In addition, the clinical manifestations of different patients in the family were significantly different.Conclusion:The novel mutation of p. k114n in SFTPC gene can lead to ILD in children, and the mutation has incomplete exons in family members.Chest CT and whole exon sequencing play an important role in the diagnosis of ILD in children.
