To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P

Objective :
To investigate the combined effects of triclosan(TCS)and PCB153 on the activity of superoxide dismutase(SOD)and the concentration of malondialdehyde(MDA)in zebrafish liver.
Methods :
Adult zebrafish were exposed to a series of concentrations of TCS,and the mortality in each group was observed and recorded during the acute toxicity test process. The concentrations in subsequent combined exposure experiments were arranged on the basis of the 96 h-LC50. The factorial design was used to determine the concentrations of combined exposure groups between TCS(0,0.125,0.5 μmol/L)and PCB153(0,0.05,0.2 μmol/L). After 5,10 and 14 days of exposure,the zebrafish livers were dissected and frozen in each group. The potential interactions of these two compounds were analyzed according to the results of the SOD and MDA.
Results :
The 96 h-LC50 of TCS exposed to adult zebrafish was 2.64 μmol/L(95%CI:2.37-2.89 μmol/L). After 5 days of exposure,combined exposure to 0.5 μmol/L TCS+0.2 μmol/L PCB153 caused lower liver SOD activities than single exposure groups and the control group(P<0.05). After 10 days of exposure,combined exposure to 0.125 μmol/L TCS+0.05 μmol/L PCB153,0.5 μmol/L TCS+0.05 μmol/L PCB153 caused lower liver SOD activities than single exposure groups and the control group(P<0.05). After 14 days of exposure,combined exposure to 0.5 μmol/L TCS+0.05 μmol/L PCB153,0.5 μmol/L TCS+0.2 μmol/L PCB153 caused higher liver SOD activities than single exposure groups and the control group(P<0.05). There was an interactive effect between TCS and PCB153 on the liver SOD activity in zebrafish(P<0.05). There was no significant effect of MDA content in each group.
Conclusion
Combined exposure to TCS and PCB153 could enhance (inhibit first) the liver SOD activities in zebrafish,and the interaction was synergistic.

Stress is a non-specific adaptive response of organisms to internal and external stimuli,which helps maintain the homeostasis of the body's internal environment.However,when the stress response exceeds the body's adaptation threshold,a variety of diseases will be induced.The morbidity and mortality of breast cancer rank the highest among female malignant tumors.Professor LIN Yi,the first master of traditional Chinese medicine(TCM)in the field of breast diseases who founded the theory of'treating breast diseases from the perspective of six stagnations',believes that six stagnations are the core pathogenesis of breast cancer,and six stagnations are closely related to the body's stress response system.TCM has unique advantages in adjusting the balance of stress homeostasis.By reviewing the classical TCM theory,the theory of'treating breast diseases from the perspective of six depressions'and the modern stress theory,this paper put forward the theory of'stress-based breast cancer prevention & treatment',and expounded the pathogenesis features,pathogenic characteristics and molecular mechanism of stress factors in mediating the development and progression of breast cancer.Moreover,the core idea and treatment principle based on the regulation of stress homeostasis were proposed,and the prescription and medication guided by the theory of'stress-based breast cancer prevention & treatment'were summarized.The establishment of the theory of'stress-based breast cancer prevention & treatment'enriches the theoretical system of breast cancer in TCM,and is expected to provide a new approach for improving the clinical prognosis of breast cancer patients.

Yinqiaojiedu honeyed pills were equally divided into 1/4, 1/8, 1/12, and 1/16 parts. The materiomics release rates within 12 h of the intact Yinqiaojiedu honeyed pills and the divided granules were determined by the paddle method with a rotate speed at 100 r x min(-1), and the materiome was quantified by UV-scan and Kalman filter methods. The intact Yinqiaojiedu honeyed pills behaved typical sustained release profiles, while the well-divided portions also maintained a sustained release profile over 2-4 h. The release rates were well correlated with the extents for the divisions of the pills. The Weibull distribution parameters, Td and T50, were reduced in line with the particle size, indicating that the ways of administration of the pills may play a role in the in vivo pharmacokinetics of the pills. The visualization results showed obvious difference of materiomic release synchronicities between the intact pills and the equally divided particles, and the divisions enhanced the asynchronization. Therefore the novel theory of materiomic release/dissolution kinetics of traditional Chinese medicines (TCMs) quantitatively proved the traditional dosage form, namely, honeyed pills, as a prototype of the sustained-release dosage form with a visualization of the scientific connotation to the old saying in the classics of TCM, Pills, the moderate ones in action. In terms of materiome increase for each period of the release profiles, the materiomic release synchronicity was visually demonstrated. The novel theories provided methodological basis for the evaluation of traditional dosage forms and the design of the modern drug delivery systems for TCMs.
