Objective To explore the correlation of cytochrome P450 gene (CYP2C19) polymorphism with hypersensitive C-reaction protein (hs-CRP), interleukin-6 (IL-6) and prognosis in patients with acute myocardial infarction (AMI). Methods A total of 182 patients with AMI admitted to cardiology department from May 2019 to May 2020 were selected as the research objects, all subjects underwent percutaneous coronary intervention (PCI), and CYP2C19 gene polymorphism in peripheral blood was detected by RT-PCR, which was grouping basis. One day after taking aspirin 300 mg and clopidogrel 300 mg orally, the levels of hs-CRP and IL-6 in patients' plasma were measured. The major adverse cardiovascular events (MACE) were followed up for 12 months after treatment. Results Among 182 patients with AMI, 78 patients (42.8%) were in the fast metabolism group (CYP2C19*1/*1), 65 patients (35.7%) in medium metabolism group (CYP2C19*1/*2, CYP2C19*1/*3), 39 patients (21.5%) in the slow metabolism group (CYP2C19*2/*2, CYP2C19*2/*3, CYP2C19*3/*3).Compared with the fast metabolism group, hs-CRP and IL-6 levels in the medium and slow metabolism group were significantly higher (P<0.05); compared with the medium metabolism group, hs-CRP and IL-6 levels in the slow metabolism group were significantly increased (P<0.05). CYP2C19 genotype was positively correlated with hs-CRP and IL-6 levels (r=0.163, 0.175,P<0.05). The incidences of MACE in the medium and slow metabolism groups were higher than that in the fast metabolism group (P<0.05). Conclusion CYP2C19 genotypes were associated with hs-CRP and IL-6 levels. Medium and slow metabolism types of CYP2C19 gene can activate the inflammatory response and affect the clinical prognosis of patients with AMI.

Objective To analyze the influence of pain nursing on the negative mood and explosive pain of patients with rectal cancer pain. Methods A total of 68 patients with colorectal cancer pain in June 2020 were included as research objects, and divided into two groups by randomized grouping.Routine clinical care was applied on the control group, pain nursing was applied on the observation group.The incidence of cancer pain, negative emotions and explosive pain in both groups of patients were compared. Results After applying different care plans, two groups of patients had a significant decrease in the SF-MPQ score (P<0.05), in which the score of the observation group was significantly lower than the control group (P<0.05), however, there were no significant differences before nursing (P>0.05). Two groups of patients were significantly improving in function scoring and the overall health scoring after receiving different care modes (P<0.05), and the observation group was significantly higher than the control group (P<0.05). The symptom dimension scores were significantly lower than before accepting different care modes (P<0.05), and the control group was significantly higher (P<0.05). The comparative results of the medicinal compliance of observation group (94.12%) were better than the control group (61.76%,P<0.05); outbreak pain comparative results showed the observation group (8.82%) was significantly lower than that of the control group (47.06%,P<0.05). Conclusion Pain nursing can be effectively used in the nursing of patients with rectal cancer pain.It can not only reduce the degree of cancer pain, but also help regulate the patient's negative mood and reduce the incidence of explosive pain.It should be widely used and promoted.
