BACKGROUND:The CD133 expression in non-smal cel lung cancer shows some changes, which is definitely related to the occurrence and development of diseases. OBJECTIVE:To investigate the expression of CD133 in non-smal cel lung cancer, and to analyze its relationship with clinical pathological factors and prognosis. METHODS:Non-smal cel lung cancer tissue specimens from 135 cases were col ected, and normal lung tissue specimens from 60 cases were set as normal control group. Immunohistochemical staining was used to detect CD133 expression in two groups, and the relationship between the expression of CD133 protein and the clinical pathological factors was analyzed. RESULTS AND CONCLUSION:(1) The positive expression of CD133 protein in the non-smal cel lung cancer group was significantly higher than that in the normal control group (P<0.05). (2) CD133 protein expression had no association with age, gender, tumor size, tumor location, histological type (P>0.05), and CD133 protein expression was significantly increased with the differentiation of non-smal cel lung cancer (P<0.05). The positive expression rate of CD133 protein was significantly different between different clinical stages and lymph node metastasis (P<0.05). (3) CD133 and TNM staging were independent prognostic factors for non-smal cel lung cancer (P<0.05), and the median survival time was significantly shorter in the positive group than in the negative group (P<0.05). The results indicate that CD133 is involved in the occurrence, development, infiltration and metastasis of non-smal cel lung cancer, and it has important clinical significance for the disease progression and prognosis.

Objective To analyze the distribution characteristics and risk factors of extended stay over 30 days at tertiary comprehensive hospitals, and explore methods of shortening average length of stay(LOS).Methods Homepage of all inpatients discharged from October 2014 to October 2015 of 31 tertiary comprehensive hospitals in Shanxi province were collected.39 234 cases of these inpatients stayed over 30 days and their case information was complete.A generalized linear model was used for risk factors analysis.Results With the extension of LOS, most of the inpatients with extended stay were found during their 30th-40th days, accounting for 50.21% of all and constituting the highest daily costs as well.The ratio of inpatients decreases with their LOS, and its distribution presents a positive skew in entirety.Distribution of inpatients over 30 days identified urban employees under medical insurance accounting for the highest ratio among all payment categories,and those from the department of orthopedics for the highest ratio among all departments, while those of diseases from injury and poisoning accounting for the highest ratio among all disease categories.The findings indicated ten important factors for extended stay, namely gender, medical payment category, ICD, inter-department transfer, nosocomial infection, and clinical pathway.Conclusions To strengthen management of specific departments and inpatients, focus on key process of medical quality, and accelerate medical insurance payment reform can effectively control extended stay.

?Objective :To construct human skin with full thickness in vitro using tissue engineering techniques. Metheods: Epithelial cells and fibroblasts were isolated from the back skin of legally aborted human foetus. Fibroblasts were seeded into bovine type I collagen gel and cultured for 3 days. Epithelial cells were seeded on the surface of collagen gel and cultured for another 2 days, then the equivalent skin was exposed to air liquid interface to generate a protective cornified layer. 5 days later, equivalent skin was excised and observed under light microscope and transmission electron microscope. Results: Epithelium and dermis were observed in the equivalent skin,similar to those in normal human skin. Epithelium was made up of stratum basale, stratum spinosum, stratum granulosum and stratum corneum. The cells of different layers were connected with intercellular bridge. Horny pearl were also found in epithelium. Basement member was observed between epithelium and dermis. Epithelial spikes bristles of different length were existed in partial dermis. The results of TEM observation showed that desmosome existed between cells of different layer in epithelium. Conclusion: Human skin with full thickness can be tissue engineered with foetus back skin as the sources of epithelial cells and fibroblasts, and bovine I type collagen as carrier.
