This thesis analyzes main manifestations of parental mental stress in childhood group incidents,and possible negative influences on the victim children and other people involved.It also points out to strengthen the understanding and intervention of parental mental status,aiming to help relieve parental mental stress,avoid upgrading of the negative incidents,and provide favorable conditions for the investigation,medical treatment,and future follow-ups for childhood group incidents.

Objective To investigate the condition of nutrition in child with cerebral palsy (CP) and the effect of nutritional intervention. Methods 49 CP children and other 60 health children (controls) were measured their bodies, hemoglobin, serum trace elements, and bone mineral density (with ultrasonic), and the feeding behavior was also investigated. Results The incidence of malnutrition was 48.97%, in which 26.53% for low weight. The levels of serum iron and zinc were poor in the CP children, and the incidence of iron deficiency anemia was 34.67% in the CP children, different from the controls (P<0.05), while the incidence of low bone mineral density was 30.61%, not significantly different from the controls (P>0.05). Feeding problems were found in 44.9% of CP children. About 50% of malnutrition was corrected, especially the body weight after 4 months of Intervention, with anemia corrected in 88.2%, and bone mineral density recovered in 50%. Conclusion It is a problem for many CP children with malnutrition and nutritional disorders, and need nutrition intervention as the content of the rehabilitation.

Objective:To explore the optimization strategy of the Asia-Pacific colorectal screening (APCS) scoring system in the screening of colorectal neoplasms.Methods:From February to Decomber in 2016 and March to December in 2018, at Xijing Hospital of Air Force Military Medical University and the First Affiliated Hospital of Xi′an Medical University, patients who received opportunistic screening colonoscopy were enrolled. Before colonoscopy, the APCS score (low-risk zero to one points, medium-risk two to three points and high-risk four to seven points), body mass index (BMI), fecal occult blood test (FOBT) and plasma methylated Septin9 gene ( mSEPT9) of all patients were detected and recorded. The results of colonoscopy and biopsy pathology were taken as the gold standard, the efficacies of the above methods in screening colorectal neoplasms were compared to determine and optimize the screening efficiency of APCS scoring system. Chi-square test was used for statistical analysis. Results:A total of 494 patients were screened, of whom 133 cases were diagnosed with colorectal polyps, including 86 cases of colorectal adenomatous polyps (82 cases of non-progressive adenoma, and four cases of advanced-adenoma), and 47 cases of non-adenomatous polyps. According to the APCS score, the detection rate of colorectal adenomatous polyps of the high-risk group (33.3%, 33/99) was 2.02 and 3.76 times higher than those of the medium-risk group (16.5%, 39/237) and low-risk group (8.9%, 14/158), respectively (both Bonferroni correction test, both P<0.016). The detection rate of colorectal adenomatous polyps of patients with BMI>23.9 kg/m 2 was significantly higher than that of patients with BMI≤23.9 kg/m 2 (22.2%, 59/266 vs. 11.8%, 27/228), and the difference was statistically significant ( χ2=9.126, P=0.003). There was no statistically significant difference in the detection rate of colorectal adenomatous polyps between patients with positive- mSEPT9 expression and patients with negative- mSEPT9 expression (22.4%, 15/67 vs. 17.3%, 47/271) ( χ2=0.913, P=0.378). Among 158 low and medium risk patients (APCS score≤three points) who underwent simultaneous BMI measurement, FOBT and plasma mSEPT9 test, the detection rate of colorectal adenomatous polyps in patients with BMI>23.9 kg/m 2 was higher than that in patients with BMI≤23.9 kg/m 2 (17.8%, 16/90 vs. 5.9%, 4/68), and the difference was statistically significant ( χ2=4.957, P=0.030). The redetection efficacy of colorectal adenomatous polyps in patients with BMI>23.9 kg/m 2 and FOBT-positive was higher than that in patients with BMI≤23.9 kg/m 2 and FOBT-negative (28.1%, 9/32 vs. 8.0%, 4/50) and the difference was statistically significant ( χ2=5.942, P=0.027). In addition, the redetection rate of colorectal adenomatous polyps of patients with positive expression of FOBT and plasma mSEPT9 was also higher than that of patients with negative expression (5/14 vs. 12.9%, 12/93), and the difference was statistically significant ( χ2=4.738, P=0.045). Conclusions:When the APCS scoring system is used for sequential screening of colorectal tumors, the optinal choice of BMI replacement or combined with FOBT can improve the patients′ compliance and screening efficiency, which has significant clinical significance and promotion value in the early diagnosis and treatment of colorectal neoplasms.
