To study the correlation between ultra high performance liquid chromatography( UPLC) fingerprint of Smilax china and its anti-pelvic inflammatory effect,and to explore the pharmacodynamic material basis of S. china against pelvic inflammatory disease.UPLC fingerprints of 10 batches of S. china from different habitats were established,and the values of SOD,MDA,TNF-α,and IL-6 in rats with pelvic inflammation were measured. The weight of each single pharmacodynamics index to the total efficacy was determined by analytic hierarchy process,and the contribution of each peak in fingerprints to the each single pharmacodynamics index and total efficacy was analyzed by the grey relational analysis. Then the structures of chemical constituents at the identified peaks were confirmed by comparing with the reference substance. The 27 common characteristic peaks of UPLC fingerprints were all related to the anti-pelvic inflammation effect of S. china,of which 13 peaks were identified as peak 2( 3,5-dihydroxy-2-methylbenzoic acid-3-O-glucoside),peak 3( chlorogenic acid),peak 5( 2,7,4-trihydroxydihydroflavone-5-O-glucoside),peak 6( 7,4-dihydroxydihydroflavonol-5-O-glucoside),peak 7( taxifolin-7-O-glucoside),peak 9( taxifolin),peak 10( polydatin),peak 11( oxyresveratrol),peak 12( astilbin),peak15( resveratrol),peak 16( quercitrin),peak 18( engeletin) and peak 24( kaempferol). The correlation degree of 21 peaks and the total efficacy was greater than 0. 8,and the top 10 ranked by correlation degree were as follows: peak 1,3,7,19,18,17,4,11,16,and 21. The results showed that the anti-pelvic inflammation effect of S. china was achieved by the combined action of pharmacodynamic substances. In order to control the quality of S. china and its prepared slices more effectively,the index components of content detection should be selected reasonably.

The paper is aimed to search more natural plant antioxidants and further research and develop new medicinal plant resources in Guizhou. The Guizhou special miao medicine "bod zangd dak" was extracted with 60% ethanol. The antioxidant activity of the different polarity components separated from the extract was tested by DPPH method with ascorbic acid as positive control. The results showed that the IC50 of the different polarity components was as following: ascorbic acid (0.033 4 g x L(-1)) < ethyl acetate components (0.052 3 g x L(-1)) < total tannins components (0.054 9 g x L(-1)) < 60% ethanol extraction components (0.076 7 g x L(-1)) < butanol extraction components (0.110 g x L(-1)) < water-soluble polysaccharides components (0.168 g x L(-1)) < water extraction components (0.174 g x L(-1)) < water components after extraction (0.226 g x L(-1)) < total polysaccharides components (0.645 g x L(-1)). It is concluded that the different polarity components have different free radical scavenging activity and that provides a scientific basis for further search of the active ingredients and the activive mechanism.

BACKGROUND/OBJECTIVES: Several medicinal properties of Smilax china L. have been studied including antioxidant, anti-inflammatory, and anti-cancer effects. However, the antiobesity activity and mechanism by which the water-soluble fraction of this plant mediates its effects are not clear. In the present study, we investigated the lipolytic actions of the water-soluble fraction of Smilax china L. leaf ethanol extract (wsSCLE) in 3T3-L1 adipocytes. MATERIALS/METHODS: The wsSCLE was identified by measuring the total polyphenol and flavonoid content. The wsSCLE was evaluated for its effects on cell viability, lipid accumulation, glycerol, and cyclic adenosine monophosphate (cAMP) contents. In addition, western blot analysis was used to evaluate the effects on protein kinase A (PKA), PKA substrates (PKAs), and hormone-sensitive lipase (HSL). For the lipid accumulation assay, 3T3-L1 adipocytes were treated with different doses of wsSCLE for 9 days starting 2 days post-confluence. In other cell experiments, mature 3T3-L1 adipocytes were treated for 24 h with wsSCLE. RESULTS: Results showed that treatment with wsSCLE at 0.05, 0.1, and 0.25 mg/mL had no effect on cell morphology and viability. Without evidence of toxicity, wsSCLE treatment decreased lipid accumulation compared with the untreated adipocyte controls as shown by the lower absorbance of Oil Red O stain. The wsSCLE significantly induced glycerol release and cAMP production in mature 3T3-L1 cells. Furthermore, protein levels of phosphorylated PKA, PKAs, and HSL significantly increased following wsSCLE treatment. CONCLUSION: These results demonstrate that the potential antiobesity activity of wsSCLE is at least in part due to the stimulation of cAMP-PKA-HSL signaling. In addition, the wsSCLE-stimulated lipolysis induced by the signaling is mediated via activation of the beta-adrenergic receptor.

OBJECTIVETo study the antitumor effects and associated mechanisms of extract of the Smilax china L. rhizome (SCR) on ovarian cancer cells.

METHODSOvarian cancer cells A2780 were treated with different concentrations of SCR extract (SCRE), and compared with controls. Effects on cell growth were evaluated by cell counting kit-8 (CCK-8) assay; proliferation effects by EdU incorporation assay; cell cycle by propidium iodide staining; apoptosis by annexin V-fluorescein isothiocyanate/propidium iodide; cellular distribution of nuclear factor-κB (NF-κB) by immunofluorescence; protein levels of NF-κB, caspase-3, poly-adenosine diphosphate (ADP)-ribose polymerase (PARP), Bcl-2-associated X protein (Bax), cellular inhibitor of apoptosis (cIAP)-1, anti-X-linked inhibitor of apoptosis protein (XIAP), B-cell lymphoma-extra large (Bcl-XL), B-cell lymphoma-2 (Bcl-2) and AKT by Western blotting; and effects of SCRE combined with cisplatin or adriamycin on A2780 cells by CCK-8 assay.

RESULTSSCRE suppressed A2780 cell proliferation in a dose-dependent manner (P<0.05,P<0.01), arrested cells in G2/M phase and induced apoptosis by activating caspase-3, PARP and Bax. SCRE treatment also correlated with inhibition of NF-κB and downregulation of Bcl-2, Bcl-XL, cIAP-1, XIAP and AKT. SCRE can promote chemosensitivity to cisplatin and adriamycin in A2780 cells (P<0.01).

CONCLUSIONSCR effectively inhibits NF-κB, induces apoptosis and reduces chemoresistance to cisplatin and adriamycin in ovarian cancer cells, which might be its molecular basis for treating ovarian cancer.

PURPOSE: Previous studies have shown that treatment with Smilax china L. leaf extract (SCLE) produces antidiabetic effects due to alpha-glucosidase inhibition. In this study, we examined the mechanism underlying these antidiabetic effects by examining glucose uptake in HepG2 cells cultured with SCLE. METHODS: Glucose uptake and glucokinase activity were examined using an assay kit. Expression of glucose transporter (GLUT)-2, GLUT-4, and HNF-1alpha was measured by RT-PCR or western blot. RESULTS: Treatment with SCLE resulted in enhanced glucose uptake in HepG2 cells, and this effect was especially pronounced when cells were cultured in an insulin-free medium. SCLE induced an increase in expression of GLUT-2 but not GLUT-4. The increase in the levels of HNF-1alpha, a GLUT-2 transcription factor, in total protein extract and nuclear fraction suggest that the effects of SCLE may occur at the level of GLUT-2 transcription. In addition, by measuring the change in glucokinase activity following SCLE treatment, we confirmed that SCLE stimulates glucose utilization by direct activation of this enzyme. CONCLUSION: These results demonstrate that the potential antidiabetic activity of SCLE is due at least in part to stimulation of glucose uptake and an increase in glucokinase activity, and that SCLE-stimulated glucose uptake is mediated through enhancement of GLUT-2 expression by inducing expression of its transcription factor, HNF-1alpha.

OBJECTIVETo study the mechanism that mediates the therapeutic effect of the bioactive fraction of Baqia (Smilax china) on chronic pelvic inflammatory disease (CPID).

METHODSSeventy rats were randomized into CPID model group, sham-operated group, normal control group, Jingangteng capsule group, and high-, medium-, and low-dose Baqia groups. Rat models of CPID were established by inducing chemical burns of the uterus and corresponding treatments were administered. After 14 days of treatment, the rat uterus was observed for swelling and inhibition rate, and the expressions of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) in the uterine tissues were determined using enzyme-linked immunosorbent assay.

RESULTSThe bioactive fraction of Baqia at the 3 doses obviously reduced the inflammatory cells in the endometrium, promoted epithelial cell proliferation, and ameliorated congestion and edema of the serosa. High and medium doses of Baqia bioactive fraction significantly decreased uterus swelling rate of the rats (P<0.01). All the 3 doses of the Baqia bioactive fraction obviously decreased uterine TNF-α content (P<0.01) and significantly increased uterine IL-4 expression level (P<0.05), and IL-4 up-regulation was especially obvious in high and medium dose groups (P<0.01).

CONCLUSIONBaqia bioactive fraction can ameliorate uterine swelling, lower uterine TNF-α and increase IL-4 expressions in rats with CPID, which may be a pharmacological mechanism underlying its therapeutic effect on CPID and cervical adhesion.

OBJECTIVETo determine the effective fraction of Smilax for treatment of chronic pelvic inflammatory disease (CPID) by pharmacodynamic screening as the basis for further development of sarsaparilla preparations.

METHODSThe chemical fractions of Smilax were administered intragastrically in rat models of CPID induced by injecting phenol mucilage into the uterus to observe the therapeutic effects. The anti-inflammatory effects of different extract fractions from Smilax were tested in mice with xylene-induced ear edema and in rats with cotton-ball-induced granuloma.

RESULTSHigh-dose ethyl acetate extract of Smilax could obviously inhibit uterus inflammation in rats with CPID, showing also strong anti-inflammatory effects against ear edema in mice and granuloma in rats (P<0.01). The moderate dose of ethyl acetate extract also obviously ameliorated the inflammation. Both the ethyl acetate extract fraction and the total extract fraction of Smilax showed anti-inflammatory effects, while the former produced strong effects while the latter has only weak actions.

CONCLUSIONThe ethyl acetate extract fraction of Smilax is the effective fraction to produce anti-inflammatory and anti-CPID effects.
