With the development of immunoassay and sensing technologies and the solid waste compost technologies being paid more and more attention,the method of immunosensor can’t be interfered by some interference factors of the commonly used analytical methods,it is of great significance to apply the immunosensor technologies in monitoring,and real-time,online measurement during compost process. The working mechanism and classification of immunosensor are briefly introduced,and the components of the complex compost system are divided into solid phase,liquid phase and gas phase. The development and application of immunosensor in compost is introduced. The latest progress in immunosensor for determination of trace toxicants is reviewed. The application of immunosensor in environmental monitoring and its future development are also discussed.

Objective To evaluate the consistency of hemoglobin (Hb) as an diagnostic index for iron deficiency anemia (IDA) in pregnant women with serum ferritin (SF) and free erythrocyte protoporphyrin (FEP).Methods Hb,SF and FEP were assayed for 506 pregnant women with various gestational weeks for the diagnosis of IDA with Hb

Objective To investigate the apoptotic effects of hypertrophic scar fibroblast (HSF) induced by HMME-PDT.Methods Fibroblasts were cultured from nontreated hypertrophic scars,and cells at passages 4-6 were used for the experiments (photosensitizer dose 4 μg/ml,λ630 nm,pow er density 10 mw/cm2,energy fluence 2.5 J/cm2).Morphological and biochemical changes in fibroblasts were assessed by Hoechst 33258 staining and fluorescence microscopy.The rate of apoptotic or necrotic cells was detected by flow cytometry (FCM) through double staining of Annexin V -FITC and popodium iodide (PI),respectively.Results Marked morphological features of cell apoptosis were viewed under the fluorescent microscope through Hoechst 33258 staining.The analysis of FCM indica ted that the apoptotic rate was significantly increased after HMME PDT [(34.82 ± I.42) ％ vs (3.12±0.28) ％,P＜0.05],and apoptotic rate was higher than necrosis rate [(14.65±1.02) ％ vs (34.82±1.42) ％,P＜0.05].Conclusions Low level exposure to 630 nm PDT mediated by HMME appears to induce fibroblast apoptosis.
