In order to improve the teaching reform of higher education systematically and op-erably, and in order to improve the effectiveness of teaching reform, teaching reform in Higher Educa-tion in the micro system engineering and SIMPP analysis method were proposed. With questionnaire survey on classroom learning state of all students from traditional Chinese medicine Grade 2010-2013 of Beijing University as an example, the principle and operation steps of SIMPP analysis method was systematically discussed. According to the students' related behavior pattern and strategy analysis affected by teachers, the analysis of the results of interpretation method and application direction was illustrated. At the same time, through the monograph, nine aspects (academic diligence level, learning effectiveness of self cognition, learning interest, teacher's influence, self-study ability, class atten-dance, learning objectives, curriculum satisfaction, major satisfaction) were analyzed by SIMPP. By modeling the related factors and their relationship, the internal relations between different factors were cleared, and the students' behavior patterns were found, and the corresponding reform measures were designed. Research shows that the concept and methods of teaching reform in Higher Education in the micro system engineering will produce a positive impact on teaching reform, curriculum reform, and the integration of family education and school education.

OBJECTIVETo explore the role of Compound Danshen Injection (CDI) in regulating the expression of aquaporin 3 (AQP3) in human amnion epithelium cells (hAECs), and to study the relation between c-Jun N-terminal kinase (JNK) signal pathway and AQP3.

METHODShAECs were isolated and primarily cultured from term pregnancy with normal amniotic fluid volume and from term pregnancy with oligohydramnios, and then hAECs were further divided into four groups, i.e., the blank control group (A), the SP600125 group (B), the CDI group (C), and the SP600125 +CDI group (D). The cell viability was measured by cell counting kit-8 assay (CCK-8). The expression of total JNK, phosphorylated JNK, and AQP3 were determined by Western blot.

RESULTS(1) In hAECs with normal AFV or with oligohydramnios: There was no statistical difference in the cell viability or the expression of total JNK among the 4 groups (P > 0.05). But there was statistical difference in the expression of p-JNK (P < 0.05). Compared with A group, the expression of p-JNK was obviously down-regulated in B group, but obviously up-regulated in C group (P < 0.05). The expression of p-JNK was significantly lower in D group than in C group, but higher than that in A group or B group (P < 0.05).The AQP3 expression in the hAECs with normal amniotic fluid volume of C group and D group were higher than that in the A group (P < 0.05). However, there was no statistical difference in the AQP3 expression between C group and D group (P > 0.05). In hAECs with oligohydramnios, the expression of AQP3 obviously decreased in B group, but up-regulated in C group (both P < 0.05). The expression of AQP3 was lower in D group than in C group, but higher than in B group (P < 0.05).

CONCLUSIONCDI could regulate the AQP3 expression in hAECs with oligohydramnios via activating the JNK signal pathway.

Objective To investigate efficiency of centipede extracts on apoptosis induction, proliferation inhibition to Human A549 cell line and growth suppression of subcutaneous transplanted sarcoma in nude mice. Methods Centipede extracts prepared by enzymolysis and acetone precipitation methods were used to treat human lung cancer A549 cell line. Proliferation inhibition was evaluated by MTT assay and half inhibit concentration (IC50) was calculated. Cell morphological change and apoptosis were detected by flow cytometry and Hoechst stain. The subcutaneous transplanted sarcoma models were prepared with nude mice and randomly divided into model group, control group and centipede extracts group, with 10 mice in each group. Changes of tumor volume, quality and anti-tumor rate were observed.Results In vitro experiment, proliferation of A549 cells was inhibited with dose-dependency and IC50 value was 0.603 mg/mL. The G0/G1 phase of cells was down regulated and G2/M and S phase cells were up-regulated. The apoptotic character cells were been found by Hoechst stain. In vivo experiment, the tumor weight and volume decreased significantly compared with model control group, with statistical significance (P<0.01).Conclusion The centipede extracts shows dose-dependent anti-proliferative effect on A549 cells, which can induce apoptosis by arresting A549 cells at G2/M phase and suppressing growth of subcutaneous transplanted sarcoma of lung cancer in nude mice.
