Purpose: To probe into the tissue damnification in progress of using modern madical instruments, the degest organs variation of low-voltage alternating current stimulation on thenar was observed. Method:the animals of experiment group were stimulated with 80V- 140V alternating current on time every days. At day of sixteenth these animals were killed,and liver and intestine histology were analyzed. Result: 1.the damnifications were distinctly in hepatocytes、hepatic sinusoid and portal area .2.the gland cells of small intestin and the cells ofsmooth muscle altered distinctly in morphology. Conclusion:Low-voltage alternating current could change the configuration of degest organs.

There has always been no lack of discussion on Biaoben and Genjie theory in traditional Chinese medical acupuncture circles, but many questions still exist. This article expounds the original meaning of Biaoben and Genjie, traces the origin of the theory and sorts out the questions in Biaoben and Genjie theory, e.g. the difference in the position between Biaoben and Genjie, no record of the location of Genjie of six hand meridians, regularities in meridional qi circulation, understanding and valuing, and application and development to confirm the importance of Biaoben and Genjie theory and to give reference.

Objective To determine kinetics of TNF-α and miR-146a (microRNA-146a)expressions in lipopolysaccharide (LPS)-induced NR8383 alveolar macrophages (AM) at different intervals and their relationships in order to explore regulatory effect and mechanism of miR-146a on alveolar macrophages inflammatory responses.Methods NR8383 alveolar macrophages were seeded in a 6-well plate,and stimulated with 1 μg/ml of LPS for 0 h,3 h,6 h and 12 h separately after 90 min.Cells were harvested and supernatant were collected 0 h,3 h,6 h and 12 h after incubation.The expressions of miR146a and TNF-α mRNA in cells were detected by real-time qPCR and the levels of TNF-α protein in the supematant of cells were assayed by enzyme-linked immunosorbent assay ( ELISA ).Pearson correlation analysis was used to analyze the correlation between miR-146a and TNF-α mRNA.Results ①The level of TNF-α protein in the supernatant of cell was significantly increased 3 h after LPS challenge ( 359.80 ±57.54) pg/ml (P <0.01 ),and peaked 12 h later (729.22 ±50.40) pg/ml (P<0.01 ) ; ②the expression of TNF-α mRNA peaked 3 h after LPS challenge (67.48 ±24.52) fold,P <0.01 ),and then decreased gradually; ③the expression of miR-146a mRNA increased continuously until 6 h or 12 h after LPS challenge 6 h:(5.33 ±0.81) fold,12 h:(8.21 ±1.19) fold,(P<0.01),and it showed an upward tendency;④ the expression of miR-146a mRNA was negatively correlated with TNF-α mRNA ( r =-0.895,P <0.01).Conclusions The miR-146a mRNA showed a negative correlation with TNF-α mRNA present in lipopolysaccharide-stimulated alveolar macrophages,suggesting miR-146a mRNA involved in regulating the inflammatory response of alveolar macrophages.

Objective:
To recombine the induced pluripotent stem cells (iPSC) derived from the urine of septic encephalopathy (SE) patients, and provided a specificity cell model to explore the mechanism of the neuronal damage and treatment for SE patients.
Methods:
Urine of SE patient was collected, and tubular epithelial cells were isolated and cultured from the urine. iPSC were derived from SE patient by introducing 4 transcription factors OCT4, Klf4, Sox2, c-Myc (OKSM) into patient-specific urine cells by Millipore's Human STEMCCATM Constitutive Polycistronic (OKSM) Lentivirus Kit. Colony morphology, alkaline phosphatase (AKP) activity, immunofluorescence staining, quantitative reverse transcription-polymerase chain reaction (RT-qPCR), and differentiation ability were used to identify the pluripetency of these iPSC lines. In addition, neurons were derived from these iPSC by inhibiting transforming growth factor-β (TGF-β) pathway.
Results:
The SE-iPSC exhibited morphological and growth characteristics of human embryonic stem cell (hES), showed positivity for AKP by histochemical staining, and expressed embryonic stem cell (ESC) marker genes. There was a significant statistical difference in ESC-marker mRNA expression between the SE-iPSC and the urine cells [NANOG mRNA (2-ΔΔCt): 1.153±0.142 vs. 0.126±0.024,
