Objective To investigate the correlation between the biomarkers related to radio-sensitivity and preoperative radiotherapy in rectal cancer patients, and to establish a logistic regression model to predict the effect of the preoperative radiotherapy through detecting the expression levels of the molecular markers. Methods 33 patients with rectal cancer who received preoperative radiotherapy from January 2010 to January 2015 were retrospectively analyzed. Patients' information was also collected including the serum level of carcino-embryonic antigen (CEA), the immune-histochemical expression levels of vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), thymidylate synthase (TS) and Ki-67, and image data (CT or magnetic resonance imaging) before radiotherapy, preoperative clinical staging and the postoperative pathologic staging. According to the postoperative pathological remission, the treatment effects of preoperative radiotherapy included effective (CR+PR) and ineffective (PD+SD) were evaluated. The relationship between these molecular markers and the curative effect of preoperative radiotherapy was analyzed by logistic regression analysis using SPSS v17.0 software, and a logistic curative effect prediction model was established. Results As a result of single factor and multiple factors logistic binary regression analysis, CEA, VEGF and Ki-67 were recognized as the interested factors for the radio-sensitivity predicting in patients with rectal cancer who received preoperative radiotherapy. A molecular markers predictive model for radio-sensitivity in preoperative radiotherapy in rectal cancer is as follow: log P=1.700-0.276×CEA-0.238×VEGF-0.135 ×EGFR+1.377 ×TS+0.080 ×Ki-67. Serum CEA level and the expression of VEGF might associate with radio-resistant, and the expression of Ki-67 might associate with better reaction to preoperative radiotherapy. Conclusion The levels of serum CEA, VEGF and Ki-67 may be the predictors of radio-sensitivity in rectal cancer patients who received preoperative radiotherapy.

Objective:To explore the effect of digital rehabilitation system on the recovery of infants with cerebral palsy.Methods:Twenty-one children with cerebral palsy were treated with residual cerebral palsy in Putuo District,and 21 children with cerebral palsy were followed up.The patients were divided into two groups (n =21).The control group was treated by routine OT training by the parents,and the treatment group was treated with the digital rehabilitation system.Three months later,the efficacy was evaluated and compared.Results:After 3 months of treatment,the total effective rate (effective rate and effective rate) of the two groups was 90.5％ and 81％,respectively,and the treatment group was significantly higher than the control group (P ＜0.05).The PROM of the two groups was improved (P ＜0.01),and the PROM in the treatment group was significantly higher than that in the control group (P ＜0.05).FMFM was significantly higher than that before treatment (P ＜0.01),and FMFM was significantly higher in the treatment group than in the control group (P ＜0.01).Conclusion:Family (community) digital rehabilitation system can effectively improve the rehabilitation of children with cerebral palsy.

Objective To analyze the expression levels of serum miR-21-5p and miR-100-5p in patients with esophageal squamous cell carcinoma(ESCC)and healthy controls,and to explore their impact on the differential diagnosis,clinical characteristics correlation,and patient prognosis of ESCC.Methods A total of 158 patients with advanced ESCC who underwent radiotherapy in our hospital's radiotherapy department from January 2018 to January 2022 were collected as the experimental group.Additionally,150 healthy individuals who underwent physical examinations were selected as the control group.Peripheral blood(5 ml)was collected from each subject,and serum was prepared.The expression levels of miR-21-5p and miR-100-5p were detected using real-time quantitative PCR(RT-qPCR).The expression differences of miR-21-5p and miR-100-5p between the experimental and control groups were compared using the t-test,and the clinical prognosis survival analysis was performed using the Kaplan-Meier method with Log-Rank test.Results Compared with the healthy control group,the expression levels of serum miR-21-5p and miR-100-5p in ESCC patients were significantly increased(both P＜0.001).The elevated expression levels of serum miR-21-5p and miR-100-5p can accurately distinguish ESCC from healthy controls,with an area under the curve(A UC)of 0.918 for combined diagnosis,a sensitivity of 93.2％,and a specificity of 87.1％.The increased expression of serum miR-21-5p and miR-100-5p in ESCC patients was correlated with later TNM stages and poorer disease-free survival and overall survival(both P＜0.05).Multivariate Cox analysis showed that TNM stage Ⅲ,high expression of serum miR-21-5p,and low expression of miR-100-5p are independent risk factors for the disease-free survival and overall survival of ESCC patients(all P＜0.05).Conclusion The expression levels of serum miR-21-5p and miR-100-5p are significantly increased in ESCC patients and indicate a poorer prognosis.Serum miR-21-5p and miR-100-5p hold promise as biomarkers for the diagnosis and prognostic prediction of ESCC.
