目的 探索干预因素对4~12岁孤独症谱系障碍（ASD）患儿社交反应的影响,为开展ASD患儿的早期干预提供参考。方法 选取于2020年1月—2023年3月在清远市妇幼保健院儿童神经与发育中心康复干预的ASD患儿,采用社交反应量表（SRS）对患儿进行社交行为评估,采用自编一般情况问卷对家长进行问卷调查,调查内容包括患儿的基本情况（性别、共患病情况、干预时长、上学情况等）。结果 202例ASD患儿中,男性患儿162例（80.2%）,女性40例（19.8%）,性别对社交反应的影响比较差异无统计学意义（t=2.969,P>0.05）。共患病方面,无共患病的ASD患儿与共患智力发育障碍及注意缺陷多动障碍的患儿相比,其SRS得分差异有统计学意义（F=6.920,P<0.05）。在上学情况方面,普通学校就读的患儿与特殊学校及未上学的患儿相比,其SRS得分差异有统计学意义（F=3.823,P<0.05）,但在特殊学校就读的患儿与未上学的患儿相比,差异无统计学意义（P>0.05）。在干预时长方面,干预≥1年与干预<1年及未干预的患儿比较,其SRS得分更低,差异有统计学意义（F=4.477,P<0.05）,但干预<1年与未干预患儿相比,两者差异无统计学意义（P>0.05）。结论 ASD患儿中,是否患有其他无共患病、上学情况、干预时长会影响其社交反应;存在共患疾病的ASD患儿社交反应表现更差;相较于就读特殊教育机构和未上学的患儿,就读于普通学校的ASD患儿社交障碍程度更轻;干预时间越长,其社交障碍程度也越轻。

Objective To explore the impact of intervention factors on social response in children with autism spectrum disorder（ASD）aged 4—12,and to provide reference for early intervention in children with ASD. Methods Children with ASD who underwent rehabilitation intervention at the Children's Neurology and Development Center of Qingyuan Maternal and Child Health Hospital from January 2020 to March 2023 were selected．The social behavior of the children was evaluated using the Social Response Scale（SRS）,and the parents were surveyed using a self-made general situation questionnaire．The survey content included the basic information of the children（gender,comorbidity,intervention duration,and school attendance,etc．）. Results Among the 202 cases of ASD,162 were male（80.2%）and 40 were female（19.8%）．There was no statistically significant difference in the impact of gender on social response（t=2.969,P>0.05）．In terms of comorbidities,there was a statistically significant difference in SRS scores between ASD children without comorbidities and those with comorbidities such as intellectual development disorder and attention deficit hyperactivity disorder（F=6.920,P<0.05）．In terms of school attendance,there was a statistically significant difference in SRS scores between children enrolled in regular schools and those who attended special schools and those who did not attend school（F=3.823,P<0.05）,but there was no statistically significant difference between children enrolled in special schools and those who did not attend school（P>0.05）．In terms of intervention duration,compared with children with intervention≥1 year and those with intervention<1 year and no intervention,the SRS score was lower and the difference was statistically significant（F=4.477,P<0.05）．However,compared with children with intervention<1 year and those without intervention,the difference was not statistically significant（P>0.05）. Conclusions No comorbidities,attending regular schools,and intervention duration≥1 year are positive factors that affect social response．Children with ASD who have comorbidities have poorer social response performance;compared to children who attend special education institutions and those who do not attend school,children with ASD who attend regular schools have lower levels of social impairment;the longer the intervention time,the lighter the degree of social impairment．

Objective To analyze the occurrence and influencing factors of bone marrow suppression in patients with non-small cell lung cancer (NSCLC) undergoing chemotherapy. Methods The clinical data of 80 patients with NSCLC who received chemotherapy in our hospital from February 2017 to August 2019 were retrospectively analyzed, the occurrence of bone marrow suppression in patients with NSCLC under chemotherapy was enrolled and grouped according to the situation; the clinical data of all patients were collected, the related influencing factors of bone marrow suppression in patients were analyzed. Results Among 80 cases of patients with NSCLC, 45 cases occurred bone marrow suppression, the incidence was 56.25%; after univariate and multivariate Logistic regression analysis, age ≥ 60 years old, chemotherapy of paclitaxel combined with platinum, TNM stage in stage III -IV, the occurrence of bone metastasis were the influencing factors of bone marrow suppression in patients with NSCLC under chemotherapy (OR>1, P<0.05). Conclusions Age ≥ 60 years old, chemotherapy of paclitaxel combined with platinum, TNM stage in stage III -IV, the occurrence of bone metastasis will increase the risk of bone marrow suppression in patients with NSCLC chemotherapy. Therefore, reasonable intervention measures can be carried out to reduce the risk.
