Objective To investigate the situation of mites breeding in student dormitories. Methods Dusts samples from beds, clothes and houses were collected every month in the same campus, separated with direcmioroscopy and identified for mites. Results A total of 1 385 specimens were collected, and the total detectable rate was 56.46%. The detectable rates of mites in dust samples collected from beds, clothes and houses were 63.73%?41.72% and 47.78% respectively, which were significant different (?2=44.43,P

Objective To investigate the expression and clinical significance of Survivin in esophageal car-cinoma.Methods Survivin expression was detected by immunohistochemistry in 61 cases of esophageal squamous carcinoma tissues and 26 tumor-adjacent normal tissues.Results The positive Survivin expression rate was 60.7% (37/61)in tumor tissues.The expression of Survivin was significantly correlated with the tumor grading,infiltration, lymph node metastasis and the survival(P<0.01).Conclusion Survivin may be an important marker for tumor di-agnosis and it is of great important to the active treatment of high-risk patients and to increasing of prognosis values.
