Conclusions The main clinical manifestations of NEC include bloody stool,abdominal distension,vomiting,apnea,intestinal perforation,etc．NEC in infants is related to sepsis,blood transfusion,respiratory distress syndrome and neonatal asphyxia．Breastfeeding and the application of probiotics are its protective factors．
目的 探讨新生儿坏死性小肠结肠炎(NEC)炎症损伤与肠道微生态-LPS-TLR4通路之间的关系。方法 本研究收集2019年3月1日—2021年1月31日在中山市人民医院新生儿监护室确诊为NEC新生儿11例为实验组,随机选取30 例同期在新生儿科病房住院喂养顺利,排除NEC及败血症诊断的新生儿为对照组。采集2组新生儿的粪便标本,进行Real-time PCR表达谱分析2组粪便肠道菌群;取2组外周静脉血检测外周血单核细胞Toll样受体4(TLR4)和血清PCT、CRP、IL-6、SAA等指标,对比2组肠道菌群、外周血单核细胞TLR4和炎症指标水平,通过统计学分析组间差异。结果 本研究结果提示实验组变形菌门占82%(9/11),厚壁菌门占9%(1/11),放线菌门占9%(1/11),对照组变形菌门占20%(6/30),厚壁菌门占73%(22/30),放线菌门占7%(2/30),2组患儿的粪便肠道菌群分布有差异(χ2=11.521,P<0.05);实验组患儿外周血单核细胞TLR4水平高于对照组,组间差异有统计学意义(P<0.001);实验组患儿血清PCT、CRP、IL-6和SAA等炎症指标高于对照组,组间差异有统计学意义(P<0.001)。结论 NEC患儿的肠道菌群以变形菌门为主,伴外周血单核细胞TLR4和外周血炎症指标升高。可见,肠道微生态-LPS-TLR4通路可能与新生儿坏死性小肠结肠炎炎症损伤相关,具体的机制仍需进一步深入研究。
Objective To investigate the relationship between intestinal flora-LPS-TLR4 pathway and the inflammatory injury of neonatal necrotizing enterocolitis (NEC). Methods Eleven neonates with NEC from March, 2019 to January, 2021 were enrolled as the experimental group, and 30 neonates without NEC and septicemia who were admitted in the department of neonatology in the same period were included as the control group. Faecal flora from the two groups were collected and analyzed by Real-time PCR. Toll-like receptor 4 (TLR4) and serum PCT, CRP, IL-6, SAA in peripheral blood were measured. The intestinal flora, the expression of TLR4 in peripheral blood leukocytes and inflammatory markers were compared between two groups. Results It showed that the ratio of Proteobacteria was 82% (9/11), Firmicutes was 9% (1/11), Actinobacteria was 9% (1/11) in the experimental group. In the control group, the ratio of Proteobacteria was 20% (6/30), Firmicutes was 73% (22/30), Actinobacteria was 7% (2/30). There was a significant difference in the distribution of faecal flora between the two groups (χ2 = 11.521, P<0.05), and the level of TLR4 in peripheral blood of the experimental group was significantly higher than that of the control group (P＜0.001). The levels of serum PCT, CRP, IL-6 and SAA in the experimental group were significantly higher than those in the control group (P＜0.001). Conclusions The main intestinal flora of neonates with NEC is Proteobacteria, with elevated TLR4 expression and inflammatory markers in peripheral blood. Therefore, the intestinal flora-LPS-TLR4 pathway may be associated with inflammatory injury in neonatal necrotizing enterocolitis.The specific mechanism still needs further study.

Objective To investigate the clinical features of infantile allergic proctocolitis and its endoscopic lesions and pathological features. Methods A retrospective analysis of 110 cases of infantile allergic proctocolitis admitted to our hospital from January 2016 to December 2018 and its colonoscopy and pathological results, food allergen-specific IgG, blood routine, fecal routine, serum total IgE detection and treatment. Results Among 110 patients with allergic proctocolitis, 67 were male and 43 were female, 98 were < 6 months old; 26 were breastfed exclusively, 19 were fed milk alone, and 65 were mixed feeding. The clinical manifestations were diarrhea, most of children with bloody stools (93 cases), some children with eczema (23 cases), defecation and crying (67 cases), restless sleep (61 cases), vomiting (8 cases), malnutrition (6 cases); blood eosinophils increased in 63 cases,serum total IgE increased in 21 cases. Food allergen-specific IgG test results:103 cases of milk, 62 cases of eggs. Endoscopic lesions involved the descending colon, sigmoid colon, rectum, 76 cases of transverse colon, 47 cases of ascending colon and 18 cases of ileocecal. Most common manifested as herpes-like changes (106 cases), erosion (97 cases), ulcers (13 cases). Histopathology showed 91 cases of intestinal mucosal eosinophil infiltration, 21 cases of cryptitis and crypt hyperplasia, 18 cases of lymphoid follicle formation and 4 cases of superficial ulcer formation. 18 cases were improved after the mother evaded diet. 8 cases were improved by feding with amino acid milk powder for one week, and then breast milk was gradually introduced; 19 cases were improved after switching to deep hydrolysis or amino acid milk powder. 65 cases were improved after switching to deep hydrolysis or amino acid milk powder and simultaneously the mother evaded diet. Conclusion Infantile allergic proctocolitis lack of insufficient specific manifestations, most of the clinical cases are good, only a few are complicated by malnutrition. Milk is the most important allergen. Diarrhea, history of blood in the stool, elevated blood eosinophils, intestinal herpes-like changes, bowel mucosal eosinophil infiltration, are suggesting a high possibility of allergic proctocolitis. Mothers avoiding diet or switching to amino acids or deep hydrolyzed milk powder treatment is also effective, and this is also the standard of diagnosis of proctocolitis.

Objective To survey the diet quality of UC patients using Chinese diet balance index(DBI-07) and explore their relationship with nutritional index and activity of disease, thereby to provide evidences of nutritional therapy for UC patients. Methods 82 adult UC patients who met the inclusion criteria were included in our study. They were investigated with food frequency questionnaires(FFQ) and diet quality was assessed with DBI-07. Anthropometric measurement and blood examinations were done. Data were analyzed with SPSS 17 software. Results 68.3% of the UC patients loss their weight during the recent 6 months. 40.2% of the patients were found hypoalbuminemia and 34.1% were complicated with anemia. The mean TS,LBS and DQD were -20.02±7.97, -22.15±6.78 and 24.27±6.21 respectively. Percentage of patients in slightly or moderately deficit of food intake were 54.9% and 37.8%. Percentage of the UC patients in slightly or moderately dietary imbalance were 80.5% and 17.1%.The absolute value of LBS and DQD were negatively correlated with serum albumin respectively, and both of them were positively correlated with activity of UC. Conclusion Evaluating the quality of UC with DBI-07,92.7% of UC patients were in slightly or moderately deficit of food intake,97.6% were in slightly or moderately dietary imbalance. These percentages were higher than that of healthy people. It indicated that deficit of food intake is an important reason resulting in malnutrition. Nutrition therapy is essential for UC patients.
目的 观察表皮生长因子(EGF)在新生儿坏死性小肠结肠炎(NEC)患儿肠组织中的动态表达情况,探讨EGF在NEC病程中起到的保护作用。方法 选取15例NEC患儿行一期回肠造瘘手术治疗的回肠组织为实验组(NEC组),将以上15例NEC患儿行二期回肠封瘘手术治疗的回肠组织为对照组(封瘘组),采用免疫组织化学技术检测,通过光密度测算软件(IPP)分析回肠组织中的EGF表达。结果 EGF主要表达于肠壁黏膜层,少量表达于黏膜下层、肌层。EGF在NEC组各层表达平均光密度值为:黏膜层(0.241±0.075),黏膜下层(0.213±0.061),肌层(0.1397±0.026),差异有统计学意义(P＜0.05);在封瘘组各层表达情况为:黏膜层(0.211±0.028),黏膜下层(0.119±0.022),肌层(0.097±0.007),差异有统计学意义(P＜0.05)。EGF在NEC组总体表达平均光密度值为(0.198±0.071),明显高于封瘘组(0.146±0.058),差异有统计学意义(P＜0.05)。结论 表皮生长因子(EGF)在新生儿坏死性小肠结肠炎(NEC)肠组织中的表达较封瘘组显著上调,推测EGF可能与NEC炎症相关,可能在NEC炎症过程中起到了一定的保护作用。
Objective We realized that EGF could play an important protective role against NEC. However, the practical condition of the distribution and expression of EGF in intestine of infants with NEC was indefinite. In order to figure out this problem,we carried out this experimentation. Methods The sample were divided into two group.The experimental group(necgroup) were composed of fifteen individual intestinal tissues after the ileostomy were performed on those infants suffered from NEC. The control group(sealing fistula group) were composed of fifteen individual intestinal tissues after the ileal closure fistula were performed on the same infants who were accepted the one-stage ileostomy in the period of NEC and were later accepted the two-stage operation on the condition that their bodies almost recovered from NEC after two to three months gone.Then, we utilized immunohistochemistry to test the distribution and quantities of EGF on those samples of the two group infants. Results The characteristic of EGF expression in intestine of the both group included strong positive expression in mucous layer and less expression in strata submucosum and muscular coat. The average optical density in nec group was mucous layer (0.241±0.075),strata submucosum(0.213±0.026),muscular coat (0.1397±0.022);In the control groupmucous layer (0.211±0.028),strata submucosum (0.119±0.022),muscular coat (0.097±0.007). The expression of EGF in intestinal tissues increased in the period of NEC0.198±0.071 by comparing with the control group (0.146±0.058). Conclusion There may be a correlation between the strong positive expression of EGF in intestinal tissues in the period of NEC and inflammation.By combining the result of this experiment and the research about EGF. We assumed that EGF is one factor of the protective mechanism by which injured intestinal mucous could be recovered and resist inflammation.
