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.

Objective To investigate the clinical features of early-on set neonatal Group B Streptococcal (GBS)septicemia in order to guide the clinical diagnosis and treatment. Methods Retrospectively analysing the clinical presentation, laboratory examination, treatment and prognosis of the 8 cases of all newborns from 2010 to 2012 in our hospital. Results The incidence of neonatal early-on set Group B Streptococcal septicemia was 6.28‰.8 cases were full-term infants in this study.Respiratory symptoms such as anhelation and cyanosis were first signs of early-on set Group B streptococcal septicemia within 24 hours after birth; 4 cases of septic shock. Results of laboratory tests included WBC:2.07~14.1×10⁹/L, in which 5 cases were ＜5×10⁹/L, N 0.54~8.32×10⁹/L. Chest X-ray: lung texture showed coarse and disorderly, leakage was increased. One case needed respiratory support with mechanical ventilation. Intravenous treatment of neonatal GBS with penicillin combined with Vancomycin was effective. Patients of serve infections should be provided supportive care. Conclusion Patients of serve early symptom of respiratory system should be paid attention. Early diagnosis and treatment should be as soon as possible to reduce fatalities.
