ABSTRACT
OBJECTIVE To explore the material basis and mechanism of expectorant and cough relief effects of the fruits of Phellodendron chinense var. glabriusulum Schneid. METHODS The expectorant and cough relief effects of volatile oil and water decoction of the fruits of P. chinense var. glabriusulum Schneid. were studied by ammonia water cough induction and drug expectorant model mice experiments； GC-MS and UPLC-MS technologies were used to identify its volatile oils and non-volatile components of the fruits of P. chinense var. glabriusulum Schneid. The active ingredients， core targets and pathways of expectoration and cough relief were analyzed by network pharmacology. RESULTS The volatile oil （0.8， 0.2 g/kg， calculated by volatile oil） and water decoction （12， 3 g/kg， calculated by crude drug） of the fruits of P. chinense var. glabriusulum Schneid. both had obvious expectorant and cough relief effects， and showed obvious dose-dependent relationship. A total of 38 volatile oil components were identified from the medicinal herbs， and the relative percentage contents of 8 components were greater than 1%， such as α -pinene， myrcene， β -caryophyllene， germanene D， isospathulenol； a total of 69 non-volatile oil components were identified， mainly including phenolic compounds， alkaloids， and flavonoids. The active ingredients screened from the identified components included 13 compounds such as α-pinene， myrcene， chlorogenic acid， luteolin， berberine. There were a total of 55 intersection targets with diseases， and the core targets were tumor necrosis factor （TNF）， epidermal growth factor receptor （EGFR）， vascular endothelial growth factor A （VEGFA）， serine/threonine kinase proteins （AKT1） and Toll-like receptor 4 （TLR4）. The molecular docking results showed that the active ingredients and the core targets had good binding ability. GO functional analysis found that the targets were significantly enriched in biological processes such as the reaction affecting lipopolysaccharides， the positive regulation of peptidyl serine phosphorylation， and the positive regulation of the biosynthesis process of nitric oxide. KEGG pathway enrichment analysis found that the targets were significantly enriched in the signaling pathways such as cancer， non-small cell lung cancer， proteoglycans in cancer. CONCLUSIONS Fruits of P. chinense var. glabriusulum Schneid. have obvious expectorant and cough relief effects， and its material basis may be α-pinene， myrcene， chlorogenic acid， luteolin， berberine， etc.， and mainly act on TNF， EGFR， VEGFA， AKT1， TLR4 and its significantly enriched signaling pathway.
ABSTRACT
OBJECTIVE： To investigate the effects of Ligustri lucidi Fructus extract on the differentiation of osteoclasts and the proliferation of osteoblasts. METHODS： Rabbit primary bone marrow cells were induced with 1a，25-Dihydroxyvitamin D3 to obtain osteoclasts. After treated with low-dose， medium-dose and high-dose of L. lucidi Fructus ethanol and water extract （both 2， 20， 200 mg/L）， TRACP activity determined method was used to detect the activity of TRACP in cell lysis solution and the number of TRACP positive cells. The number of celluar bone resorption lacunae and the percentage of bone lacunae area were detected by toluidine blue staining. Osteoblasts were obtained by L-ascorbic acid， β-sodium glycerophosphate and dexamethasone-induced subcloning 14 of cranial parietal anterior osteocytes in mice. MTT assay and APK activity assay were used to detect relative proliferation rate of cells and the activity of APK. RESULTS： After treated with different doses of L. lucidi Fructus extract， the number of TRACP positive cells， the number of bone resorption lacunae and their area were changed in varying degrees. TRACP activity， the number of its positive cells， the number of bone resorption lacunae and the percentage of bone lacunae area in different dosage groups of L. lucidi Fructus ethanol extract and high-dose of water extract； the TRACP activity， the number of its positive cells and the percentage of bone lacunae area in L. lucidi Fructus water extract medium-dose group were decreased significantly， while the number of bone resorption lacunae in L. lucidi Fructus water extract low-dose group was increased significantly （P＜0.05 or P＜0.01）. The relative proliferation rate of cells in L. lucidi Fructus extract low-dose and medium-dose groups and APK activity of cells in extract groups were significantly increased， while the relative proliferation rate of cells were decreased significantly in L. lucidi Fructus ethanol extract and water extract high-dose groups （P＜0.01）. CONCLUSIONS： L. lucidi Fructus extract can inhibit TRACP activity of osteoclasts， change the bone resorption function of osteoclasts and the proliferation behavior of osteoblasts and increase APK activity of osteoclasts.
ABSTRACT
Objective: To verify the existence of microRNAs (miRNAs) extracted from fresh ginseng decoction. Methods: Fresh ginseng was prepared into decoction according to the conventional method. The miRNA were extracted from the condensed ginseng decoction by plant microRNA extraction kit. Then miRNA were treated by DNase I and subjected to agarose gel electrophoresis and Agilent 2100 bioanalysis. MiR-159 and miR-6135, which were highly expressed in ginseng, were selected and verified by real-time quantitative PCR to detect the expression in the decoction. Results: Ginseng miRNA were successfully extracted from fresh decoction. MiR-159 and miR-6135 were expressed in fresh decoction with lower levels than those of fresh ginseng. Conclusion: miRNAs stably existed after processing, and retained some stability after high-temperature treatment. The findings provide a valuables basis for the further studies on ginseng miRNAs.

ABSTRACT
OBJECTIVE:To study the common characteristic component peaks in water decoction of crude curcumae radix and the vinegar roasted products from 4 different sources,compare the contents of its water decoction,and provide reference for resolv-ing the multi-source of curcumae radix piece in clinical application,complementing and improving the quality standard of curcumae radix. METHODS:HPLC was used to determine the characteristic spectrums of crude curcumae radix and the vinegar roasted prod-ucts from different sources (Curcuma wenyujin,Curcuma kwangsiensis,Curcuma longa,Curcuma phaeocaulis),and component analysis was conducted by using fingerprint software and mirror comparison. And the changes of water decoction content before and after vinegar roasted were compared. RESULTS:Both crude curcumae radix and the vinegar roasted products from 4 different sourc-es had 7 common characteristic component peaks. Vinegar roasted had effect on peaks in different degree,some peaks areas were in-creased,some peaks areas were reduced,some peaks were generated,and some peaks were disappeared. However,the common components of curcumae radix from different sources showed no qualitative changes after vinegar roasted,except the increase or de-crease in peak areas. Areas of 5 common component peaks were increased in the 7 common components of C. wenyujin,C. kwang-siensis and C. longa after vinegar roasted,and only 3 in C. phaeocaulis after vinegar roasted. Contents of 4 water decoctions were increased after vinegar roasted. CONCLUSIONS:There are 7 common components in curcumae radix from 4 different sources. Vin-egar roasted has no qualitative effect on common components,while it can increase the chromatographic peak areas and contents of water decoction.
