Chinese Journal of Information on Traditional Chinese Medicine 2006;0(06):-
Objective To study the extraction process of Jiejiu Gankang granules by orthogonal test.Methods With the ethanol extraction rates of the medical materials like ginseng,radix salviae miltiorrhizae,the water extraction rates of the medical materials like hawthorn,and Tanshinone ⅡA as the parameters,the extract conditions of Jiejiu Gankang granules was optimized by orthogonal design.Results The optimal preparation process was as follows:the mixture of medical materials like ginseng and Schisandra chinensis was refluxed twice with total 10 times of 70% alcohol,2.0 hours for each time,and then the mixture of medical materials like hawthorn extracted twice with total 10 times of boiling water,2.0 hours for each time.Conclusion The optimal preparation process is reasonable and with high extraction rate of active components.

OBJECTIVETo explore different regulatory effects of electroacupuncture (EA) at the same acupoint on the heart and the stomach.
METHODSEighty male SD rats were randomly divided into eight groups equally, i.e., the Neiguan (PC6) group, the Quchi (LI11) group, the Tianshu (ST25) group, the Danzhong (RN17) group, the Zusanli (ST36) group, the Sanyinjiao (SP6) group, the Xinshu (BL15) group, and the Weishu (BL21) group, 10 in each group. The regulatory effects of EA (2/15 Hz, 3 mA, 2 min) at different acupoints on the gastric motility (intragastric pressure) and the cardiac function (the left ventricular pressure) were observed. The mean values of effect of two-min pre-EA and after-EA were compared.
RESULTSCompared with the pre-EA in the same group, the left ventricular pressure decreased in the Neiguan (PC6) group, the Quchi (LI11) group, the Danzhong (RN17) group, the Sanyinjiao (SP6) group, and the Xinshu (BL15) group (P <0.05). The intragastric pressure increased in the Quchi (LI11) group, the Zusanli (ST36) group, the Sanyinjiao (SP6) group, and the Xinshu (BL15) group, while it decreased in the Tianshu (ST25) group, the Danzhong (RN17) group, and the Weishu (BL21) group (P <0.05). The difference of the left ventricular pressure was sequenced from high to low as Xinshu (BL15) >Danzhong (RN17) >Neiguan (PC6) >Sanyinjiao (SP6) >Quchi (LI11). The difference of the intragastric pressure was sequenced from high to low as Tianshu (ST25) >Weishu (BL21) > Xinshu (BL15) > Danzhong (RN17) > Zusanli (ST36) > Sanyinjiao (SP6) > Quchi (LI11).
CONCLUSIONSEA at the same acupoint (2/15 Hz, 3 mA) showed different regulatory effects on the heart and stomach. There existed some difference in the direction and size due to the acupoint location, meridians, dominant nerve segment or relating organs. A fixed effect direction to the specific target was also shown.

BACKGROUND:It has been confirmed that carboxymethylated chitosan has an promoting effect on Schwann cel proliferation and secretion, but its impact on the cyclic adenosine monophosphate-mediated protein kinase A signaling pathway in schwann cel stil needs further study. OBJECTIVE:To investigate the effect of carboxymethylated chitosan on cyclic adenosine monophosphate/ protein kinase A signaling pathway in rat schwann cels. METHODS:The Schwann cels of the second generation neonatal rats were obtained and seeded in 6-wel plate at a concentration of 1×109/L. These Schwann cels were cultured and divided into four groups. The Schwann cels in the control group were cultured by adding PBS. The Schwann cels in the experimental groups were cultured by adding 50, 100 and 200 mg/L of carboxymethyl chitosan solution, respectively. After 24 hours, the concentration of cyclic adenosine monophosphate, protein kinase A activity and cyclic adenosine monophosphate response element binding protein mRNA expression were detected. RESULTS AND CONCLUSION:Compared with the control group, carboxymethyl chitosan increased cyclic adenosine monophosphate concentrations, the activity of protein kinase A and cyclic adenosine monophosphate response element binding protein mRNA expression within the Schwann cels in a dose-dependent manner (P < 0.05). These results demonstrate that carboxymethyl chitosan can increase the concentration of cyclic adenosine monophosphate within the Schwann cels and promote protein kinase A activity, thereby activating cyclic adenosine monophosphate/protein kinase A signaling pathway.
