Game relationship of mutual restriction and mutual connection exist among various segments of Chinese medicine decoction pieces supply chain. Any problems in any segments will affect quality and safety of the whole supply chain, and ultimately affect the safety of consumers. Based on the theory of supply chain, this article established a linear supply chain and static game model, including planting farmers, production and marketing society, processors of Chinese medicine decoction pieces, terminal consumers and middle sales section whichis made up of whole sale and retail markets and manufacturing enterprises of Chinese patent medicine. This article also proposed the suggestions about quality safety of Chinese medicine decoction pieces through quantitative methods in game theory.

Objective To observe the effects of betulinic acid (BA) on proliferation of human hepatoma stem cell;To discuss its anti-cancer mechanism from the aspects of cell cycle and cell apoptosis. Methods HepG2 stem cells were cultivated in vitro and testified the self-renewal capacity. The effects of BA in concentration of 40, 20, 10, 5, 2.5, 1.25μmol/L on the cell vitality of cultured human liver cancer stem cells for 24 and 48 hours were measured with CCK-8 method. The human hepatoma stem cell line HepG2 was administrated by BA at concentrations of 40, 20, 10, 5μmol/L for 48 hours, and cell cycle and apoptosis rate were measured by flow cytometry. Results BA could inhibit HepG2 stem cell proliferation obviously with dose-effect relationship. BA influenced cell cycle, and induced tumor stem cell apoptosis. 40μmol/L BA blocked cell cycle in S phase, and cell apoptosis rate reached 10.86%. Conclusion BA has obvious inhibitory effects on proliferation of HepG2 liver cancer stem cell, which probably plays a part in anti-cancer by influencing cell cycle and inducing cell apoptosis.

Objective To measure the endogenous metabolites in synovial tissues of rheumatoid arthritis (RA) rabbits with cold syndrome;To investigate the specificity mechanisms of heat-reinforcing needling for RA. Methods A total of forty healthy purple blue rabbits were randomly allocated to normal group, model group, reinforcing-reducing needling group (RRN), twirling-reinforcing needling group (TRN) and heat-reinforcing needling group (HRN) 8 rabbits in each group. Arthritis rabbits cold model was made with ovalbumin and freezing. Except for normal groupand model group, RRN was given acupuncture of reinforcing-reducing needling at Zusanli (ST36), TRN was given acupuncture of twirling-reinforcing needling at Zusanli (ST36), HRN was administrated acupuncture of heat-reinforcing needling at Zusanli (ST36), once a day and retaining 30 min, a total of seven days. Fresh synovial tissues of rabbits knee joints were extracted after the intervention, then GC-Q/TOF-MS technology were employed to evaluate metabolic profiles. Results The synovial tissues metabolites of TCA cycle, carbohydrate and fatty acid metabolism in model group mainly increased compared with normal group (P<0.05); The synovial tissues metabolites of various kinds above-mentioned decreased compared with model group in all intervention of acupuncture group (P<0.05), and the metabolites of TCA cycle and carbohydrate metabolism in HRN were obviously less than that of RRN and TRN (P<0.05). Conclusion The specificity of heat-reinforcing needling for RA manifests in regulation of TCA cycle and carbohydrate metabolism.

The etiology of pulmonary fibrosis is complex. The occurance and development of this disease involve many cell signal transduction pathways, including MAPK signaling pathway, JAK-STAT signaling pathway, Smad signaling pathway, PI3K-Akt signaling pathway, NF-κB signaling pathway and so on. Numbers of experiments have shown that intervention in signal transduction pathways with TCM can delay the progression of fibrosis, which provides good therapeutic methods for this disease. This article reviewed study on TCM intervention in different signal transduction pathways in the pulmonary fibrosis in China.

Objective To analyze the medication rules of Professor ZENG Bin-fang’s treatment for chronic hepatitis B (CHB); To provide references for clinic. Methods Research data came from patients with CHB in outpatient and hospitalization in Department of Hepatology, Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region. In this study,data mining methods, such as complex network analysis and dot-mode mutual information, were utilized to conduct analysis on the syndromes, symptoms, treatment and medication of included patients, as well as the mutual relations. Results The study collected clinical data of 132 patients with CHB, who accepted 277 times of examination,and 277 prescriptions were included. High-frequency symptoms included:burnout and weakness, abdominal distension, hypochondriac pain, and lower limb edema; Common syndromes included:stagnation of liver qi and spleen deficiency, retention of damp-heat in the interior, liver and gallbladder damp-heat, liver qi stagnation, and qi-stagnation and blood stasis, etc., successively, including 126 times of examination and accounting for 45.5%of all cases. Common therapeutic methods involved in soothing liver and strengthening spleen, eliminating dampness and heat, nourishing liver and kidney, regulating vital energy and promoting blood flow and activating blood and activating spleen, successively. Dot-mode mutual information analysissyndrome-symptom relation:the differentiation point of stagnation of liver qi and spleen deficiency included burnout and weakness, thirst,dull pain of right lateral thorax, anorexia, and abdominal distension;syndrome-therapy relation:stagnation of liver qi and spleen deficiency contained the main therapeutic method of nourishing liver and strengthening spleen;syndrome-medicine relation: Bupleuri Radix, Codonopsis Radix, Scutellariae Radix, Angelicae Sinensis Radix, Paeoniae Radix Rubra,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, Pinellinae Rhizoma Praeparata, raw Rehmanniae Radix, and Cyperi Rhizome. Analysis of complex network analysis showed that the core formula for stagnation of liver qi and spleen deficiency was Xiaochaihu Decoction and Siwu Decoction. Conclusion The treatment thinking of Professor ZENG Bin-fang for CHB pays attention to entire concept, attaches importance to Zang-fu transmission, regards“nourishing liver, soothing liver and strengthening spleen”as the therapeutic principle, together with nourishing yin, softening and resolving hard mass, clearing heat-toxin and eliminating dampness.

Conclusion Evaluating Angelicae Sinensis Radix based on AHP fuzzy comprehensive evaluation model is feasible.

Objective To establish a method to simultaneously determine syringing and isofraxidin by HPLC;To investigate the features of percutaneous absorption in vitro of Jiegugao blended and pasted by white vinegar, honey and vaseline; To discuss the mechanism of commonly used ointment matrices in Tujia Minority. Methods Rat abdomen skin in vitro was as transdermal barrier;the modified Franz diffusion pool was used to simulate human skin medication; the content of syringin and isoprofen was determined by HPLC; the percutaneous absorption equation was established and the related parameters, such as cumulative permeation rate and permeation rate, were calculated. Results When using Syncronis C18 (250 mm × 4.6 mm, 5 μm) as chromatographic column, acetonitrile-0.1%phosphoric acid as mobile phase, 1.0 mL/min as perfusion speed and 265 nm as determine wavelength, regression equation of syringingwas A=10 686.454 6C+1565.778 8 (r=1.000 0), regression equation of isofraxidin was A=12 297.305 4C-5913.729 9 (r=0.999 9). Cumulative permeation quantity of syringing in Jiegugao blended and pasted by white vinegar, honey, vaseline and blank were 7.549 2, 4.580 3, 3.890 8 and 5.378 4 μg?cm-2?h-1 respectively and permeation rate were 25.66%, 16.11%, 13.73% and 18.78%. Meanwhile, cumulative permeation quantity of isofraxidin were 2.536 9, 1.941 8, 1.178 2 and 2.293 6 μg?cm-2?h-1 respectively and permeation rate were 47.04%, 35.06%, 22.11%and 41.11%. Conclusion Using white vinegar as the ointment matrix can promote the percutaneous absorption of effective composition in Jiegugao blended. However, it will retard the percutaneous absorption of effective composition in Jiegugao when using honey and vaseline as the ointment matrices, but honey and vaseline can be used as a slow-release matrix.
