The combination of chemotherapy, radiotherapy and targeted therapies are considered to be major treatments for metastatic pancreatic cancer. At present, the target therapy-related medications include mainly antagonist of epidermal growth factor receptor, monoclonal antibody of vascular endothelial growth factor and so on. Erlotinib combined with gemcitabine has been demonstrated to prolong the survival of patients with pancreatic cancer.

The key of individualized therapy is that using molecular markers to select more suitable drug.At present,some studies have confirmed that certain molecular markers can predict the efficacy of the drugs.For example,cetuximab is beneficial in patients with K-ras wild-type colorectal cancer,gefitinib and erlotinib are beneficial in patients with epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer( NSCLC),imatinib is beneficial in patients with C-KIT gene-positive gastrointestinal stromal tumor.In terms of safety,the promoter polymorphism of UDP glucuronosyltransferase 1 polypeptide A1 ( UGT1 A1 ) can predict the toxicity of irinotecan.

Esophageal cancer is one of the most common gastrointestinal cancers, and chemoradiotherapy is an important part of the multidisciplinary treatment for this disease.In recent years,18Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET-CT) is widely used in esophageal cancer for delineation of gross tumor volume, local boost irradiation in the late stage of radiotherapy, and assessment of the pathologic remission rate after neoadjuvant chemoradiotherapy, response to definitive chemoradiotherapy, and prognosis.In this article, we review the application of FDG PET-CT in the chemoradiotherapy for esophageal cancer.

Esophageal cancer is a common gastrointestinal cancer in China with poor prognosis.Radiotherapy is the main treatment of esophageal cancer,and radiosensitivity of the tumor cell is a significant reason for the efficacy of radiotherapy.Mesenchymal-epithelial transition factor (c-Met) and its signaling pathway play an significant role in tumorigenesis,development,invasion,metastasis and treatment resistance.This review summarizes the association between expression of c-Met and radiosensitivity in esophageal cancer.

Objective: To explore the impact of maternal anxiety during pregnancy on social emotional development of toddlers aged 1-3 year old, so as to provide references for scientific early parenting and early intervention for toddlers with social emotional difficulties. Methods: From September 2022 to March 2023, a total of 815 toddlers aged 1-3 who underwent physical examinations and their mothers at Nantong Maternal and Child Health Hospital were enrolled. The Chinese Infant Toddler Social and Emotional Assessment (CITSEA) was used to evaluate the social emotional ability among toddlers. Maternal anxiety evaluated using the Self rating Anxiety Scale (SAS) during prenatal visit was collected. Results: The average scores on the externalizing, internalizing, dysregulation and competence domains of the CITSEA were (49.40±9.48,47.42±9.60,48.67± 10.15 , 50.07± 10.20), respectively. Among boys, the score of externalizing domain (50.89±9.45) was higher than that of girls (48.76± 9.50 ), while the score of competence domain (49.22±10.30) was lower than that of girls (51.17±9.84), and the differences were statistically significant( t =2.10, -3.03, P <0.05). The detection rates of abnormalities in the externalizing, internalizing, dysregulation, and competence domains were 7.36%, 7.12%, 7.61%, and 7.24%, respectively. Among them, boys (8.43%,6.32%, 7.96 %,7.49%) and girls (6.19%, 7.99 %,7.22%,6.96%) showed no statistical differences ( χ 2=1.50, 0.85, 0.16, 0.09, P >0.05). There were significant differences in externalizing domain scores（47.77±9.52，49.56±8.95，52.51±9.77） and competence domain scores（51.70±10.38，49.65±10.05，46.68±10.03） among toddlers of different maternal anxiety（normal, mild, moderate to severe） （ F =7.05,7.10, P <0.01）. There were significant differences in the abnormal detection rate of externalizing domain （4.81%，7.54%，11.17%） and competence domain（4.81%，6.96%，11.73%）（ χ 2=6.60，7.98， P ＜0.05）. Conclusion Maternal anxiety during pregnancy has a negative impact on the social emotional development among toddlers. In order to improve social emotional development of toddlers, multidimensional social support and education during pregnancy should be carried out.

Objective:To understand the sensory characteristics of children with autism spectrum disorder (ASD), and to explore its relationship with the clinical symptoms and to provide a reference basis for early diagnosis and intervention treatment of ASD.Methods:A cross-sectional survey was conducted to collect 216 children diagnosed with ASD according to DSM-5 from September 2021 to December 2021.All children were investigated with short sensory profile (SSP), autism behavior checklist (ABC) and social response scale (SRS). SPSS 21.0 was used for statistical analysis and the correlation between sensory characteristics and clinical symptoms of ASD children was analyzed by Pearson correlation.Results:The results showed that 120 of 216 with ASD children had abnormal SSP total score, with an abnormal rate of 55.6%.Among the seven dimensions, the abnormal rate of auditory filtering was the highest, reaching 83.8%, followed by low strength/weakness(60.2%), motor sensitivity(43.5%), low response/sensation seeking(39.8%), taste/smell sensitivity(37.5%), vision / hearing sensitivity(27.8%) and tactile sensitivity(17.6%), and the total incidence of paresthesia was 92.1%.There were significant differences in the total score of ABC and the five dimensions of sensation, communication, body movement, language and life self-care of ASD children with different sensory characteristics ( F=39.15, 39.99, 46.02, 29.18, 50.98, 51.76 respectively, all P<0.01). There were significant differences in the total score of SRS and social perception, social cognition, social communication, social motivation among ASD children with different sensory characteristics ( F=19.33, 29.47, 24.82, 29.68, 31.48, 39.86 respectively, all P<0.01). With the aggravation of sensory abnormalities, the total scores of ABC and SRS and the scores of each dimension increased.The total score of SSP was negatively correlated with the scores of sensation, communication, body movement, language, self-care and the total score of ABC ( r=-0.613, -0.631, -0.643, -0.558, -0.657, -0.679 respectively, all P<0.01). The total score of SSP was negatively correlated with social perception, social cognition, social communication, social motivation, autism behavior and the total score of SRS ( r=-0.440, -0.527, -0.504, -0.522, -0.542, -0.595 respectively, all P<0.01). Conclusion:Sensory abnormalities are common in ASD children, and with the aggravation of sensory abnormalities, the core symptoms and behavioral performance of ASD children are more obvious and positively correlated.

Objective: To understand sensory characteristics and its correlation with behavioral problems among children with autism spectrum disorder (ASD), so as to provide reference basis for early diagnosis and comprehensive intervention of ASD children. Methods: Using cross sectional survey, 193 ASD children trained by Nantong rehabilitation institutions were recruited from September 2021 to February 2022. All children were investigated with the Short Sensory Profile (SSP) and Parent Symptom Questionnaire (PSQ). Results: Among the 193 ASD children, 106 (54.9%) children had abnormal sensory characteristics, including 45 (23.3%) with possible abnormalities and 61 (31.6%) with obvious abnormalities. The abnormal rate of auditory filtering was the highest in the seven dimensions, reaching 85.0%, followed by low strength/weakness, motor sensitivity, taste/smell sensitivity, low response/seeking sensation, vision/hearing sensitivity and tactile sensitivity. The total incidence of sensory abnormalities was 93.3%. There were significant differences in six dimensions of PSQ scale scores of ASD children with different degrees of sensory abnormalities, including conduct problems, learning problems, psychosomatic disorders, impulsive hyperactivity, anxiety and hyperactivity index ( H =38.89, 38.90, 19.53, 46.34, 34.54, 54.90, P <0.01). With the aggravation of sensory abnormalities in children with ASD, the scores of all dimensions of the PSQ scale increased significantly. The total score of SSP was negatively correlated with the six dimensions of conduct problems, learning problems, psychosomatic disorders, impulsive hyperactivity, anxiety and hyperactivity index in PSQ ( r =-0.53, -0.50, -0.32, -0.55, -0.43, -0.61, P <0.01). Conclusion ASD children generally have sensory abnormalities, which coincide with severity of behavioral problems. There is a positive correlation between sensory abnormalities and behavioral problems in ASD children. More attention should be paid to the abnormal sensory characteristics of children with ASD in the future diagnosis and treatment process.

【Objective】 To observe the effects of mirror neuron system theory(MNST) on hand dexterity and fine motor function in preschool children with developmental coordination disorder(DCD), so as to provide reference for the rehabilitation of children with DCD. 【Methods】 A total of 51 children with DCD treated at Nantong Maternal and Child Health Care Hospital from June 2021 to April 2023 were enrolled in this study, and were randomly assigned to treatment group (n=26) and control group (n=25) except for 5 cases who missed in the follow-up. Both groups received conventional rehabilitation training, while the treatment group received MNST additionally. The hand dexterity and fine motor function of both groups were assessed using the hand dexterity subscale of the Movement Assessment Battery for Children-Second Edition (MABC-2), Peabody Developmental Motor Scale-Fine Motor (PDMS-FM), and Function Independence Measure for Children (WeeFIM) before and after 12 weeks of treatment. 【Results】 Before treatment, there were no significant differences in hand dexterity subscale of MABC-2, PDMS-FM, and WeeFIM scores between the two groups (P>0.05). After treatment, both groups showed improvements in hand dexterity subscale of MABC-2, PDMS-FM, and WeeFIM scores (treatment group: t=35.620, 42.084, 40.072; control group: t=14.000, 12.017, 14.054, P<0.001), with the treatment group showing significantly greater improvements compared to the control group (t=2.611, 3.120, 2.331, P<0.05). 【Conclusion】 MNST combined with conventional rehabilitation training can enhance hand dexterity and fine motor function in children with DCD, thereby improving children′s activities of daily living.

ObjectiveTo apply pneumatic hand rehabilitation equipment in comprehensive rehabilitation training to improve hand function in children with spastic hemiplegic cerebral palsy. MethodsFrom Januray, 2020 to September, 2021, 58 children with spastic hemiplegia cerebral palsy in Maternity and Child Health Care Hospital of Nantong University were randomly divided into control group (n = 29) and experimental group (n = 29). Both groups accepted comprehensive rehabilitation training, while the experimental group accepted pneumatic hand rehabilitation equipment training in addition, for six months. They were assessed with Peabody Developmental Motor Scales-Fine Motor (PDMS-FM), Fine Motor Function Measurement (FMFM) and Wee-Function Independence Measure (Wee-FIM) before and after training. ResultsThe scores of PDMS-FM, FMFM and Wee-FIM improved in both groups after training (|t| > 16.310, P < 0.001), and improved more in the experimental group than in the control group (t > 2.795, P < 0.01). ConclusionApplication of pneumatic hand rehabilitation equipment in comprehensive rehabilitation training can effectively promote the recovery of hand function for children with spastic hemiplegic cerebral palsy.

OBJECTIVES: To investigate changes of pulmonary ventilation function and diffusion function in lung cancer patients after neoadjuvant immune checkpoint inhibitors (ICIs) therapy combined with chemotherapy treatment. METHODS: Patients with newly diagnosed lung cancer (Ⅱa-Ⅲb) admitted to Zhejiang Cancer Hospital from October 2021 to July 2022, who received ICIs combined with chemotherapy for more than two courses were enrolled. Patients underwent pulmonary ventilation function and diffusion function assessments before and after treatment. The demographic information, sizes and locations of cancer lesions, doses and duration of ICIs used, pulmonary function results before and after treatment, and the tumor regression were documented. The changes of pulmonary function parameters before and after the treatment were analyzed with paired t test and Wilcoxon rank-sum test. The factors influencing the pulmonary function changes were analyzed by multiple linear Lasso regression and ridge regression. RESULTS: Among the 52 patients, 50 cases were males (96.15%) and 43 cases were squamous carcinoma (82.69%). The medium age of the patients was 67 years. After neoadjuvant therapy, 36 patients (69.23%) showed remission of tumor lesions. After treatment, the parameters of pulmonary ventilation inspiratory vital capacity (IVC) and the area under the expiratory flow-volume curve (AREAex), and the parameter of pulmonary diffusion total lung capacity increased compared with the baseline (all P<0.05). Forced vital capacity (FVC) and forced expiratory volume in first second (FEV₁) also showed an increasing trend. Multivariate linear Lasso regression and ridge regression showed that baseline IVC had a significant negative effect on IVC improvement (Beta=－0.435, t=－2.968, P<0.01), baseline TLC had a significant negative effect on the improvement of TLC (Beta=－0.266, t=－2.474, P<0.05), and the remission of obstructive pneumonia favored the improvement of TLC (Beta=0.308, t=2.443, P<0.05). CONCLUSIONS After ICIs neoadjuvant treatment combined with chemotherapy, the lung ventilation and diffusion function can be improved in lung cancer patients, particularly for those with reduced baseline ventilation and diffusion function.
