This article introduced what sick building syndromeSBSis. Besides its concept evolvement of definition criteria of diagnosis of SBS the relationships between SBS building-related illness BRI and multiple chemical sensitivity MCS which are the other two main diseases caused by indoor air contamination was elucidated at the same time its prevalence level characters dangerous factors and its research methods were discussed briefly. Controlling molecule contamination is thought as an important and effective method to eliminate SBS.

ObjectiveTo observe effects of modulated medium frequency low frequency current hydroelectric bath therapy on sequela of ankle fracture.Methods32 sequela patients of ankle fracture were treated with ZM-C type intellectual faculties intermediate frequency therapeutics instrument. Modulated medium frequency square all wave,the frequency of carry wave was 4 KHz,and the frequency of modulated wave was 100 Hz. The water temperature was 40℃. 30 minutes was a time,12 times was a course. Before and after treatment,results were contrasted themselves.ResultsAfter treatment,32 patients all got satisfactory effects,the shorter of the course,the better of the effect.ConclusionThe modulated medium frequency low frequency current hydroelectric bath therapy is a simple,safe and better effect method for sequela of ankle fracture.

Objective To explore the apoptosis of alveolar epithelial cell(AEC)and the dynamic changes of Caspase-3 mRNA and Bax and Bcl-2 expression in premature rat with hyperoxia-induced chronic lung disease(CLD).Methods Sixty premature rats within 1 day after birth were randomly divided into 2 groups:hyperoxia group(n=30)and control group(n=30).Hyperoxia-induced premature rat CLD models were prepared,and situ nick end-labeling(TUNEL),reverse transcription polymerasechain reaction(RT-PCR)and immunohistochemical technique were used to determine apoptosis index(AI)of AEC and the expressions of Caspase-3 mRNA and Bax and Bcl-2 proteins in lung tissues at 1,3,7,14 and 21 d after birth.Results Compared with control group,in the hyperoxia group,on the third day after exposured to hyperoxia,the AI of AEC and the expressions of Caspase-3 mRNA and Bax began to increase,and the expression of Caspase-3 mRNA was kept at high level on 7-21 d.The expression of Bcl-2 began to decrease on 7 d,and significantly decreased on 7-21 d.AI of AEC was positively correlated with the expression of Caspase-3 mRNA and Bax,and negatively with the expression of Bcl-2.Conclusions Hyperoxia may induce the increased expression of Caspase-3 mRNA,which might result in the abnormal expression of Bax and Bcl-2 in lung tissues and their imbalance,which might be one of the underlying mechanisms of apoptosis of AEC in premature rats with CLD.
