Objective:To investigate the expressions of tumor stem cell marker CD133 and tumor vascular endothelial cell marker CD105 in lung cancer tissue and their clinical significance.Methods:Streptavidin-biotin-peroxidase complex (SABC)-immunohistochemical staining was used to detect the expression of CD133 and CD105 in 65 cases of lung cancer tissue and 30 specimens of adjacent non-cancerous tissue. The relationship between the expression of CD133/CD105 and tumor size, histological types, differentiation, TNM stage, lymphoid metastasis, and prognosis were analyzed. Results:The positive expression rates of CD133 and CD105 in lung cancer tissues were significantly higher than those in adjacent non cancerous tissues, respectively (69.2% vs 26.7% and 67.7% vs 10.0%, both P<0.05). The positive expression rates of CD133 and CD105 in the group with lymphoid metastasis were higher than those with non lymphoid metastasis, respectively (82.5% vs 48.0% and 80.0% vs 48.0%, both P<0.05). The expressions of CD133 and CD105 were positively correlated with lymphoid metastasis with Pearson coefficient r of 0.35 and 0.32, respectively (P<0.05). No significant correlation was found between the expression of CD133/CD105 and tumor size, histological types, differentiation degree as well as TNM stage(P>0.05). The expression of CD133 was positively correlated with the expression of CD105 in lung cancer tissue with Pearson coefficient r of 0.37 (P<0.05). Postoperative median survival periods of CD133 and CD105-positive group were significantly shorter than the CD133 and CD105-negative groups (37 months vs 66 months,35 months vs 70 months, respectively, both P<0.05). Conclusion:The expression of CD133 and CD105 was associated with lymphoid metastasis and prognosis in patients with lung cancer.Their overexpression implies poor prognosis of lung cancer patients.

To determine the impact of IL-23 knockdown by RNA interference on the development and severity of ovalbumin (OVA)-induced asthmatic inflammation, and the potential mechanisms in mice, the IL-23-specific RNAi-expressing pSRZsi-IL-23p19 plasmid was constructed and inhaled into OVA-sensitized mice before each challenge, as compared with that of control mice treated with alum or budesonide. Inhalation of the pSRZsi-IL-23p19, significantly reduced the levels of OVA-challenge induced IL-23 in the lung tissues by nearly 75%, determined by RT-PCR. In addition, knockdown of IL-23 expression dramatically reduced the numbers of eosinophils and neutrophils in BALF and mitigated inflammation in the lungs of asthmatic mice. Furthermore, knockdown of IL-23 expression significantly decreased the levels of serum IgE, IL-23, IL-17, and IL-4, but not IFNgamma, and its anti-inflammatory effects were similar to or better than that of treatment with budesonide in asthmatic mice. Our data support the notion that IL-23 and associated Th17 responses contribute to the pathogenic process of bronchial asthma. Knockdown of IL-23 by RNAi effectively inhibits asthmatic inflammation, which is associated with mitigating the production of IL-17 and IL-4 in asthmatic mice.

Objective To investigate the effect and feasibility of early enteral nutrition support on postoperative nutrition assessments and clinical outcomes in children patients with congenital heart disease. Methods From October 2013 to October 2014, a number of 100 cases congenital heart disease aged six months to two years old were treated with early enteral nutrition support after operation. According to gender, fifty patients were randomly divided into the intervened group, who were treated with the early enteral nutrition support program. The other fifty patients were divided into control group with no nutrition sup-port. The detailed early enteral nutrition support project were( a) withdraw breathing machine at the same day, giving enteral nutrition 6 hours later after postoperation;( b) patients assist with long-term breathing machine, giving enteral nutrition 12-24 hours later after postoperation. The age, heigth, weight, serum C- reactive protein(CRP), serum retinoic binding protein ( RBP) , serum prealbumin( Pre-ALB) were recorded before operation. Seven days after operation, above indicators were ob-served again. In addition, the first time of excrete, the number of feeding interruption, the time of feeding, the time of ventila-tor, and the related complications were also recorded at hospitalization period. Results No difference of basic information and accompanying complications were observed between control and nutritional intervention group. As to nutritional status, weight-for-age z-score(WAZ) were significant higher in the nutritional intervention group than the control group( -0. 22 ± 1. 16 vs. 0.73 ±1.29, P=0.019) after operation. However length/height-for-age z-score(LAZ/HAZ) and weight-for-length/height z-score( WLZ/WHZ) were similar between control and nutritional intervention group whatever pre-operation and postoperation. Preoperative CRP, RBP, and Pre-ALB were no significant difference between early enteral nutrition and control group. After operation CRP levels in the early enteral nutrition group were significantly lower than that of control group[(45.2 ±16.2)mg/L vs.(67.3±35.5)mg/L,P<0.001],whileRBP[(0.3±0.1)mg/Lvs.(0.2±0.1)mg/L]andPre-ALB[(35.2±12.2)g/Lvs.(25.2±14.2)g/L] weresignificantlyhigherthanthoseofcontrolgroup(Pvaluewere0.031and0.029,respective-ly) . In the early nutritional intervention group and control group, the first time of excrete were remarkable in advance in nutri-tionalinterventiongroupcompredtocontrolgroup[(36±12)hvs.(65±15)h,P=0.008],whilethedifferenceoffeeding interruption times, intensive care unit( ICU) time and mechanical ventilation time in the two groups were not statistically signif-icant(P>0. 05). Conclusion Early nutritional intervention can help gastrointestinal function, enhance nutritional status, lower serum CRP levels and increased serum RBP and Pre-ALB concentrations. It did not add ICU time and ventilation time.
