[Objective] To guide the clinical application of Fuyang medicine through the study of San Jiao Theory of ZHENG Qin'an [Method] To study the foundation theory of ZHENG Qin'an and correlate the evidence with the concept of original yang, San Jiao, Emporer fire, Minister fire and middle earth. To explain the unity and inter-relation of San Jiao and the symptons of yang deficiency of San Jiao and the approach of the use of medicine with the support of case studies. [Result] Zheng Qin'an suggested that three Jiaos are of one Jiao. The yang of upper jiao is governed by Emperor fire while that of lower Jiao by Minister fire. The two fires are of one fire. The circulation of the two fires generates the middle earth. When the middle yang fails on circulating the upper and lower Jiaos cannot communicate. The root of original yang is the kidney which is nourished by the spleen. The unity of San Jiao, the use of lower yang as the root of upper and middle yang and the use of the circulation and root nourishing action of middle yang are the keys to application of medicine. [Conclusion] The use of medicine of ZHENG strongly adhered to the qi circulation of San Jiao. It showed to the later generations a simple but comprehensive thought of Chinese medicine. It was an important guidance for the use of Fuyang medicine.

Objective To review and investigate the malaria control history of Wuzhou City,Guangxi Zhuang Autonomous Region from 1950 to 2015,so as to provide the evidence for future malaria control and surveillance. Methods The data of ma?laria control in Wuzhou City from 1950 to 2015 were collected and analyzed. Results In 1950 decade,the malaria incidence in Wuzhou City was 1 435.55/100 000,higher than the average level in Guangxi,and the mortality of malaria was 0.95/100 000. The malaria incidence of local residents was reduced to 3.61/100 000 in 1979 and no local malaria case was found since. The im?ported malaria cases were found in Wuzhou City since 1980,and were more than local cases since 1981. In recent five years, 87.50%(7/8)of imported malaria cases were from south?east Asia. Conclusions Wuzhou City has reached the national criteri?on of malaria elimination,but the imported malaria is the recent threat. The surveillance and control work of malaria should be strengthened.

OBJECTIVETo explore whether the function of the CL-1 hepatocytes, co-cultured with human hepatic stellate cells (HSC) on microcarriers was better than that cultured without HSC.

METHODSCL-1 hepatocytes were divided into 2 groups. The co-culture group was cultured with HSC in DMEM culture medium containing 10% fetal bovine serum, and HSC were not added in single-culture group. The cytomorphology was observed by inverted microscope and scanning electron microscopy. The effects of different culture method on the proliferation in vitro were analyzed by MTT assay. The function of hepatocytes was evaluated through measuring the concentration of ALT and albumin.

RESULTSThe inverted microscope and the MTT staining results showed that the quantity and viability of the human hepatocyte (C3A) in bidirectional bioreactor group were much better than the RCMW group. The growth curve results showed that the density of the human hepatocyte (C3A) was firstly increased and then decreased in both groups, and the peak of the curve appeared in day 5. The density of human liver cells in the second generation of bi-directional rotation and perfusion microgravity bioreactor group was significantly higher than the RCMW group from day1 to day 7 (P<0.05). The functional results showed that the albumin and urea concentration, which reached the peak on day 5, also gone up firstly and then gradually gone down in both teams. And the albumin and urea concentration in bidirectional bioreactor group was significantly higher than RCMW group from day 1 to day7 (P<0.01). Besides, the concentration of ALT and AST in bidirectional bioreactor group was significantly lower than RCMW group from day 1 to day 7 (P<0.05).

CONCLUSIONThis study shows that this new culture method is advantageous in enhancing cell viability and function. It indicates that co-culturing hepatocytes with HSC has a good application prospect in the development of artificial liver technology.
