Objective To investigate the expression of epidermal growth factor receptor (EGFR) and multidrug resistance protein, and it's relationship with efficacy of chemotherapy in NSCLC.MethodsThe immunohistochemical (EnVision method) was used to detect the expression of EGFR and LRP, P-gp, MRP, GST-π in 95 cases of NSCLC tissues and 15 cases of normal lung samples.ResultsEGFR in NSCLC tissues was significantly correlated with the history of smoking, pathological types of cancer(squamous cell carcinoma vs adenocarcinoma), presence of lymph node metastasis, and TNM stages (P< 0.05).The positive expression rate of LRP and MRP in adenocarcinoma were higher than squamous cell Carcinoma (P< 0.05), and MRP in high differentiate cancer was higher than low differentiate cancer (P< 0.05).The expression of MRP and LRP, PGP and GST-π in NSCLC were positive correlation(r=0.341, P=0.001;r=0.213, P=0.038), there is no correlation between EGFR with LRP, P-gp, MRP, GST-π.EGFR-negative chemotherapy efficiency (62.5%) was significantly higher than EGFR-positive(37.5%, P< 0.05).ConclusionEGFR and multi drug resistance proteins are overexressed in NSCLC tissues.multi drug resistance proteins have a synergistic to drug resistance.EGFR could be used to objectively predict chemotherapy effect and prognosis of NSCLC.

Objective To investigate the expression of phosphorylation-mammalian target of rapamycin (p-mTOR) in endometrial carcinoma. Methods The expressions of p-mTOR protein in tissues from 45 cases of endometrial adenocarcinoma, 7 endometrial atypical hyperplasia, and 6 normal endometrium were detected by immunohistochemistry SP method. Results The expression of p-mTOR protein maily restricted to cytoplasm. Compared with normal endometrium, the expression of p-mTOR protein in the cases of endometrial atypical hyperplasia and endometrial adenocarcinoma was significantly up-regulation(2.36 ± 0.76vs 6.21 ± 1.19, 15.82 ± 2.64)( F = 11.37, P ＜ 0.05 ). There was significant difference of p-mTOR protein in different histology class in endometrial adenocarcinoma (F = 8.27, P ＜ 0.05), but there was no significant difference of p-mTOR protein in different pathological grade in endometrial adenocarcinoma (P ＞0.05).Conclusion The expression of p-mTOR protein may participate in the occurrence and development of endometrial carcinoma.

Objective: To explore the effect of LBP X on apoptosis of human leukemia HL 60 cells. Methods: The inhibitory effect of LBP X on growth of HL 60 cells was assayed by MTT method. The membrance fludity was determined with DPH fluorigenic labeling technique. HL 60 cells were stained with Hoechst 33 258 for nuclear morphology analysis. Agarose gel electrophoresis and flow cytometry were used to analyze apoptosis qualitatively and quantitatively. Results: 20-1 000mg/L LBP X inhibited the growth of HL 60 cells in dose dependent manner and the membrance fludity decreased. The nuclei of HL 60 cells treated with LBP X for 48 h shrinked, condensed and cleaved. Agarose gel electrophoresis of DNA from cells treated with LBP X revealed "DNA ladder". HL 60 cells exposed to LBP X showed apoptotic peaks. Conclusion: LBP X can induce apoptosis in human leukemia HL 60 cells.

Electroencephalography (EEG) is an important instrument for the evaluation of brain function, and an irreplaceable diagnostic technique for nervous system diseases. At present, China still lacks professional child-EEG talents. Therefore, it is a task of great priority to establish an effective and practical training method and foster more child-EEG physicians. As most trainees have not learned EEG before and only have limited time for learning, we divide the child-EEG training into three phases, includ-ing theory learning, practice training, and EEG reading and interpretation on the basis of the general rules in learning EEG. In the theory learning phase, basic EEG knowledge is taught comprehensively to form a solid foundation for future study. In practice training phase, the trainees acquire important skills of EEG by carrying out complete EEG monitoring, eliminating EEG artifacts, observing seizures, and read real-time EEG. In the phase of EEG reading and interpretation, the trainees learn to analyze EEG gradually by read-ing and report EEG under the guidance of the senior physician. Strict examination is arranged for each phase to evaluate study results objectively. The phased model is designed to implement a step-by-step training of child-EEG and foster the trainee's independent ability to carry out EEG inspection.
