Action Mechanism of Chinese Medicine Polysaccharides in Prevention and Treatment Diabetes and Its Complications：A Review / 中国实验方剂学杂志

Diabetes is a metabolic disease mainly characterized by hyperglycemia due to inadequate insulin secretion. And persistent hyperglycemia can cause chronic damage or dysfunction of eyes， kidneys， heart， blood vessels and nerves. Polysaccharides are high molecular carbohydrates polymerized by glycosidic bonds from more than 10 monosaccharide molecules of the same or different types. They have the advantages of wide sources， high safety and low toxic and so on. As one of the important effective components of traditional Chinese medicine， polysaccharides have biological activities such as immune regulation， anti-oxidation， anti-tumor， lowering blood sugar and so on. The structure is directly related to biological activities， and the advanced structure of polysaccharides is based on the primary structure. Exploring the primary structure of polysaccharides is the key task of lowering blood sugar and improving diabetic complications. This paper summarizes the monosaccharide composition of the primary structure of Chinese medicine polysaccharides， and the mechanism of Chinese medicine polysaccharides improving diabetes is emphasized by increasing the secretion and release of insulin， increasing the islet β cell number， upregulating insulin receptor level， improving glucose and lipid metabolism， inhibiting inflammatory response， improving oxidative stress and regulating phosphatidylinositol-3-kinase（PI3K）/protein kinase B （Akt）， mitogen activated protein kinase， cyclic adenosine monophosphate（cAMP）/protein kinase A（PKA） and adenosine monophosphate activated protein kinase（AMPK） signaling pathways. At the same time， we also summarized the prevention and treatment of Chinese medicine polysaccharides in diabetic nephropathy， diabetic cardiomyopathy， diabetic ophthalmopathy and diabetic peripheral neuropathy， in order to provide a theoretical basis for new drug development and clinical application of Chinese medicine polysaccharides in the intervention of diabetes and its complications.

According to the analysis on average blood flow rate, traditional Chinese medicines with natural and cold properties showed similar effect on heat stagnation and blood stasis syndrome and better effect in increasing blood flow rate than those with hot property; those with natural and hot properties showed similar effect and better effect in increasing blood flow rate than those with cold property.</p><p><b>CONCLUSION</b>Under the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with those with cold property; wile under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with the Chinese medicinal herbs with hot property. This indicates the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property to some extent.</p>

The establishment and evaluation of the model rats of blood stasis and heat accumulation syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To establish a rat model of blood stasis and heat accumulation syndrome in accordance with the Chinese medicine (CM) theoretic features.</p><p><b>METHODS</b>Thirty male SD rats were randomly divided into the normal group, the model group, and the danshen root group, 10 in each. Rats in the danshen root group were given danshen decoction at 13.5 g/kg by gastrogavage, with the volume of 20 mL/kg, twice daily for 7 successive days. As for rats in the normal group and the model group, equal volume of pure water was given to them by gastrogavage, twice daily for 7 successive days. On the 4th day of medication, carrageen at 50 mg/kg was peritoneally injected to rats in the model group and the danshen root group, once daily for 3 successive days. Twenty-four h after the last injection, 20% dry yeast suspension (10 mL/kg) was given to the rats by subcutaneous injection. The indictors such as body temperature, tongue figure, tail ecchymosis, skin color of the ears and four limbs, microcirculation indicators, and hemorheological indicators were observed 6 h later.</p><p><b>RESULTS</b>Compared with the normal group, red and purple tongue, longer and thicker arteries and veins under the tongue, red and purple claw color, red ear flap edge, obvious ecchymosis of the tail occurred in rats of the model group (P<0.01), with obviously increased body temperature (P<0.01). The blood velocity of the microcirculation in the ear flap obviously decreased. The hemorheology tests showed that the whole blood viscosity (high, middle, and low), hematocrit, and erythrocyte electrophoretic time obviously increased, red blood cell deformation index obviously deceased, showing statistical difference (P<0.01, P<0.05). Compared with the model group, the length of ecchymosis in the tail obviously decreased in rats of the danshen root group. The blood velocity score of the microcirculation obviously increased. The hemorheology tests showed that the whole blood viscosity (high, middle, and low), hematocrit, and erythrocyte electrophoretic time obviously decreased, red blood cell deformation index obviously increased, showing statistical difference (P<0.05, P<0.01).</p><p><b>CONCLUSION</b>The rat model of blood stasis and heat accumulation syndrome established with carrageen and dry yeast suspension injection had obvious features, with good reproducibility and stability. It could be used in the study of CM basic theories, screening of Chinese herbs, and the theories of Chinese-drug properties.</p>
