Anti-tumor Effect of Shikonin： A Review / 中国实验方剂学杂志

The incidence and mortality of cancer are increasing year by year， seriously threatening human health. At present， the chemotherapy-based treatment of cancer can prolong the survival time of patients， but its severe side effects and adverse reactions often lead to poor prognosis. Therefore， searching for anti-cancer drugs with high efficiency and low toxicity has become the focus of clinical attention from all over the world. The effective components of Chinese medicine have the advantages of mild side effect and multi-target regulation， and their anti-tumor activities are highly favored by many researchers. Shikonin， a naphthoquinone compound， is the main effective component of Arnebiae Radix， with anti-tumor， anti-inflammatory， antioxidant， and other pharmacological effect. Studies have shown that shikonin possesses significant anti-tumor activities against a variety of tumor cells， and it can inhibit the development of many cancers， such as breast cancer， lung cancer， liver cancer， cervical cancer， ovarian cancer， colon cancer， and prostate cancer. The anti-tumor mechanism of shikonin is mainly related to multi-pathway and multi-target inhibition of tumor cell proliferation， the promotion of reactive oxygen species （ROS） production， induction of tumor cell apoptosis， cell cycle arrest， and tumor cell autophagy， and the inhibition of tumor cell migration and invasion. In addition， shikonin can increase the sensitivity of tumor cells to anti-tumor drugs and reverse the drug resistance of tumor cells. The signaling pathways involved in the anti-tumor effect of shikonin include phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， PI3K/Akt/mammalian target of rapamycin （mTOR）， mitogen-activated protein kinase （MAPK）， pyruvate kinase M2/signal transducer and activator of transcription protein 3 （PKM2/STAT3）， and Kelch-like epichlorohydrin-related protein 1/nuclear factor E2-related factor 2 （Keap1/Nrf2）. The anti-tumor effects are mainly achieved through the regulation of the PI3K/Akt signaling pathway. Based on the relevant literature on the anti-tumor effect and mechanism of shikonin in China and abroad， the present study reviewed the research progress in the past three years to provide useful references for the further study of the anti-tumor effect of shikonin and the research and development of new antineoplastic drugs.

The findings are of great significance to the rational application of Citri Sarcodactylis Fructus， the development of health food， and the research of new drugs and will bolster the development of Chinese medicine industry.

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.

Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.

Classification and morphology of jugular bulb and its clinical significance / 中华神经医学杂志

Objective To observe the anatomic and imaging morphology ofjugnlar bulb and its relationship with the surrounding structures, and to investigate the classification ofjugnlar bulb and its clinical significance. Methods We dissected 30 human temporal bones and studied multi-slice spiral CT imaging data of temporal bone of 120 cases and blood vessel cast mould specimen of the jugular bulb of 6 cases, to observe the morphology of jugnlar bulb and its spatial relationship with the surrounding structures. We made an imagined sagittal plane on the medial well of the tympanic cavity, with a horizontal tangent line of the proximal wall of the tympanic cavity and a vertical tangent line of the posterior wall of the tympanic cavity as coordinate axes (X axis and Y axis), respectively, so the 4 quadrants ( Ⅰ , Ⅱ, Ⅳ, Ⅳ) were formed. The jugular bulb was classified intro 4 types according to the quadrant where its top was projected and subtyped according to its position on the inner or outer side of the plane. The operation via mastoid approach was simulated on specimen to observe the effect of jugnlar bulb on the operation route. Results Some jugular bulbs were flat type and others were prominent types. The classification in the group of CT image: type Ⅰ , 11 case (9%);type Ⅱ, 63 cases (53%);type Ⅲ, 25 cases (21%);type Ⅳ, 21cases (17%). The classification in the group of specimen: type Ⅰ, 1 case (3%);type Ⅱ, 11 cases (37%);type Ⅲ, 8 cases (27%);type Ⅳ, 10 cases (33%). Each type of the jugular bulb had different effects on the operative approach. Conclusions The classification method with the 4 quadrants is a simple and three-dimensional way to describe the position of the jugular bulb for imaging diagnosis or operative scheme design.
