Objective To investigate the relationship between serum T cell immunoglobulin mucin mole-cule-3(TIM-3)and netrin-1(NTN-1)levels and the risk of recurrence of B-cell acute lymphoblastic leukemia(B-ALL).Methods A total of 60 children with B-ALL were selected from January 1,2021 to January 1,2023.According to the expression of fusion gene,the children were divided into fusion gene positive group(26 ca-ses)and fusion gene negative group(34 cases).The blood routine,inflammatory factor levels,TIM-3 and its ligand galectin-9(Gal-9),NTN-1 and its downstream protein phosphorylated protein kinase B(pAKT)and protein kinase B(AKT)levels were compared between the negative fusion gene group and the positive fusion gene group at admission.The patients were followed up for 1 year and the recurrence of B-ALL was counted.The difference of serum TIM-3 and NTN-1 levels between the children with recurrence and those without re-currence was compared,and the correlation between the levels of TIM-3 and NTN-1 and recurrence was ana-lyzed.Results Compared with before treatment,the levels of TIM-3 and Gal-9 in both groups decreased after treatment,and the differences were statistically significant(P＜0.05).Compared with before treatment,the levels of TIM-3 and Gal-9 in both groups were decreased after treatment,and the differences were statistically significant(P＜0.05).The levels of NTN-1 and pAKT in fusion gene positive group were significantly higher than those in fusion gene negative group,with statistical significance(P＜0.05),but there was no statistical significance in AKT comparison(P＞0.05).In the follow-up period,there were 9 cases(34.61％)of recur-rence in the fusion gene positive group and 2 cases(5.88％)in the fusion gene negative group.The recurrence rate in the fusion gene positive group was higher than that in the fusion gene negative group,and the differ-ence was statistically significant(P＜0.05).The levels of TIM-3 and NTN-1 in recurrent children were sig-nificantly higher than those in non-recurrent children,and the difference was statistically significant(P＜0.05).Multiple Logistic regression analysis showed that TIM-3 and NTN-1 were independent risk factors af-fecting the prognosis of children(P＜0.05).Serum TIM-3 and NTN-1 levels were positively correlated with the risk of recurrence of B-ALL(r=0.445,0.437,P＜0.05).Conclusion The levels of TIM-3 and NTN-1 are different in different types of B-ALL,which can reflect the risk of recurrence of B-ALL,and it is recom-mended to pay close attention to them.

ObjectiveTo investigate the effects of psychological intervention on patients with acute coronary syndrome (ACS) accompanied by psychogenic disturbance.Methods112 patients with ACS were evaluated with depression status inventory (DSI) and symptom checklist-90 (SCL-90). The cases accompanied with depression were randomly divided into the psychological intervention group (group A) and drug group (group B). Patients of group A were treated with psychological intervention besides routine therapy. The curative effects of the two groups were compared.Results79 cases (70.5%) had depression. Their scores of somatization, depression, anxiety, fear, paranoid ideation, and total score and positive symptom distress level of SCL-90 were significantly different compared with the normal group. After psychological intervention, to patients of the group A, the DSI score fell and symptoms improved significantly (P<0.01), the in-patient duration shorten (P<0.05).ConclusionPsychogenic factors is not neglectable in the process and prognosis of ACS. Effective psychological intervention can promote the patient's healing.
