Objective To explore the effect of motivational interview in the psychological counseling and management abilities of family caregivers of children with recurrent wheezing.Methods A total of 120 children with recurrent wheezing who were treated in Hangzhou Children's Hospital from May 2023 to May 2024 were selected.The family caregivers of children were randomly divided into control group and observation group,with 60 people in each group.The control group received conventional knowledge training and health education,while the observation group received motivational interviews based on control group.Compare the asthma control level,anxiety and depression levels of family caregivers of children,scores of various dimensions of the family caregivers of children management measurement scale,and satisfaction between two groups before and after intervention.Results After intervention,the frequency of recurrent wheezing in observation group was lower than that in control group,and the difference was statistically significant(P＜0.05).There was a statistically significant difference(P＜0.05)in family management measure scores between two groups before and after intervention.The satisfaction of family caregivers of children in observation group was significantly higher than that in control group,and the difference was statistically significant(P＜0.05).Conclusion Motivational interview intervention can effectively alleviate the wheezing frequency of children with recurrent wheezing,improve the response of family care,reduce anxiety and depression of family caregivers of children.

Heart failure is the leading cause of death worldwide. Compound Danshen Dripping Pill (CDDP) or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China. However, the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown. We constructed a new model of heart failure induced by hypercholesterolemia/atherosclerosis in apolipoprotein E (ApoE) and LDL receptor (LDLR) dual deficient (ApoE^-/-LDLR^-/-) mice and investigated the effect of CDDP or CDDP plus a low dose of simvastatin on the heart failure. CDDP or CDDP plus a low dose of simvastatin inhibited heart injury by multiple actions including anti-myocardial dysfunction and anti-fibrosis. Mechanistically, both Wnt and lysine-specific demethylase 4A (KDM4A) pathways were significantly activated in mice with heart injury. Conversely, CDDP or CDDP plus a low dose of simvastatin inhibited Wnt pathway by markedly up-regulating expression of Wnt inhibitors. While the anti-inflammation and anti-oxidative stress by CDDP were achieved by inhibiting KDM4A expression and activity. In addition, CDDP attenuated simvastatin-induced myolysis in skeletal muscle. Taken together, our study suggests that CDDP or CDDP plus a low dose of simvastatin can be an effective therapy to reduce hypercholesterolemia/atherosclerosis-induced heart failure.

Objective To explore the factors affecting methylphenidate (MHP)efficacy in children with attention deficit hyperactivity disorder (ADHD). Methods One hunadard eleven DSM-Ⅳ defined ADHD patients were enrolled for 6 weeks systemic MHP titration treatmnet. ADHD Rating Scale-Ⅳ Home Version (ADHD-RS-Ⅳ) were applied as index of clinical efficacy, and Continuous Performance Task (CPT) as index of cognition efficacy. Determining potential influential factors was analyzed on MPH efficacy including demographic,baseline clinical symptoms and cognitive factors. Results Sixty-five (59.1%) were defined as responders and 45 (40.9%) as non-reponders to MHP, respectively. CPT which were conducted in 87 patient showed that 35 (40.2%) were defined as responders on commission errors, 31 (35.6%) on omission errors and 10 (11.5%) on reaction time. Logistic analysis revealed two potential influential factors that predicted better clinical efficacy (P<0.05): better parental relationship (OR=3.516, 95% CI: 1.087~11.375) and baseline ADHD-RS-Ⅳ score above 35 points (OR=3.075, 95%CI: 1.131~8.359). Higher IQ score was the potential influential factor that predicted better commission errors efficacy (OR=1.085, 95%CI: 1.013~1.162) and omission errors efficacy (OR=1.078, 95%CI: 1.008~1.153). Conclusion MHP efficacy may result in better outcomes in children with ADHD who have higher baseline ADHD-RS-Ⅳ score, poorer baseline CPT result, younger onset age, higher IQ and better parental relationship.

Objective To explore the difference of methylation status of CpG island in promoter re?gion of DAT1 and DRD4 genes between children with attention deficit hyperactivity disorder ( ADHD) and normal controls,and further understand the pathogenesis of ADHD from a epigenetics point of view. Methods 111 ADHD patients and 118 normal controls were enrolled in the present study. The demographic data and peripheral venous blood were collected from both groups. Bisulfite genomic sequencing ( BGS) was used to confirm the methylation status of every CpG site in promoter region of DAT1 and DRD4 genes. Results No significant differences were found between ADHD patients and normal controls on percentage of methylated CpG sites in total CpG islands for both DAT1 and DRD4 (P>0.05) . However,the percentage of methylation in No. 17 CpG site for DAT1 and No. 8 CpG site for DRD4 was higher in ADHD patients ( 23. 42% and 64.86% respectively)compared with that in normal controls(11.86% and 47.46% respectively)(P<0.05).In all samples,the percentage of methylated CpG site in total CpG island for DAT1 was higher in males com?pared with that in females(P<0.05),whereas that for DRD4 was higher in females compared with that in males (P<0.05);the same gender difference on methylation level for DAT1 was also found in ADHD patients and for DRD4 in normal controls(P<0.05) . In all samples and in ADHD patients,percentage of methylated CpG site in total CpG island for DAT1 was higher in individuals over 7 years old compared with that in indi?viduals younger than or equal to 7 years old(P<0.05). Conclusions Methylation status of CpG island in DAT1 and DRD4 genes promoter region might correlate with ADHD susceptibility.Methylation status of CpG island in DAT1 and DRD4 genes show differences in different age span and sex.

BACKGROUND:There are many reports on the clinical effect of total knee arthroplasty in the treatment of advanced rheumatoid arthritis, but the reports on the effect of total knee arthroplasty on the disease activity in patients with rheumatoid arthritis are rare. Therefore, the more clinical evidences are needed for supporting.
OBJECTIVE:To explore the effect of total knee arthroplasty on disease activity in patients with rheumatoid arthritis.
METHODS:109 patients with rheumatoid arthritis were included;48 cases in the replacement group, and received total knee arthroplasty combined with internal medicine medications;the 61 cases in the drug treatment group were treated with simple internal medicine medications. The rheumatoid factor, blood sedimentation rate and C-reactive protein levels of the patients in two groups were measured before treatment, 1 and 2 years after treatment, and the Ishikawa joint function scoring criteria was used to assess the functions.
RESULTS AND CONCLUSION:There were no significant differences in the rheumatoid factor, blood sedimentation rate and C-reactive protein levels between two groups before treatment (P>0.05). At 1 and 2 years after treatment, the indicators in the drug treatment group were higher than those in the replacement group (P<0.05);the indicators in the two groups at 2 years after treatment were significantly lower than those before treatment (P<0.05). The rheumatoid arthritis symptom scores of the affected joints of the patients in two groups were significantly improved, especial y the pain, swel and subjective attitudes, and the replacement group was better than the drug treatment group (P<0.05). The total knee arthroplasty can affect the disease activity of rheumatoid arthritis in short-term, and the effect of total knee arthroplasty is better than simple drug treatment.
