Objective: To study the effect of light quality on the growth as well as triterpenic acid content and component of Ganoderma lucidum mycelium. Methods: Light-emitting diode (LED) was used as sources of light, the growth index, content and component of triterpenic acids in G. lucidum mycelium cultured under different LED conditions were investigated along with culture time. Results: The growth rate, morphology, biomass, total contents and components of triterpenic acid in G. lucidum mycelium varied under different lights. The mycelium cultured under blue light maintained stable growth during the whole period; Under red light, both growth rate and biomass of mycelium were the highest in early time, subsequently, decreased sharply and grew slowly. Under green light, both growth rate and biomass of mycelium were the lowest in early and medium phases, while increased significantly later, especially dry matter. Triterpenic acids were highly produced on the day 7 of cultivation, while decreased in content and increased in types. Green light and blue light had a distinct advantage of improving the type and content triterpenic acids in G. lucidum. Conclusion: Light quality affects the growth as well as the content and component of triterpenic acids in G. lucidum mycelium, and blue light irradiation is the best for the steady growth and triterpenic acids accumulation.

Objective To investigate the effect of standard remnant liver volume (SRLV) on liver insufficiency after hepatectomy in cirrhotic patients with hepatocellular carcinoma (HCC).Methods Sixty-seven HCC patients with liver cirrhosis were involved in this study.The following parameters were obtained in all cases:total liver volume (TLV),resected liver volume by surgery,body surface area (BSA),remnant liver volume (RLV)and SRLV.Compared analysis of relationship between liver insufficient and the parameters as well as the age of patients,duration of operation and blood lose etc.was carried out,in order to establish the security threshold of SRLV.Results According to the postoperative liver function,the patients were divided into 2 groups:Group A,52cases with mild liver dysfunction; Group B,15cases among them 12 with moderate and 3 with severe liver insufficiency.Statistical analysis showed that the difference of TLV,duration of operation,intra-operative blood lose and age between Group A and B were insignificant(P＞0.05).However,that of RLV and SRLV were significant(P＜0.05).The average SRLV in Group A was 562±89 ml/m2 and 410±87 ml/m2 in Group B (P＜＜0.01).The security threshold of SRLV was 438 ml/m2 calculated by receiver operating characteristic (ROC)in our patients.Then randomly selected sixty HCC patients,the incidences of moderate and severe liver insufficiency postoperative in the SRLV≤438 ml/m2 and SRLV＞438 ml/m2 patients were 92.3％and8.5％ (P＜0.01).Conclusions It is suggested from our present study that SRLV is a good predictor for post-operative liver function reserve in patients with cirrhotic HCC.Its security threshold is 438 ml/m2,and the risk of occurring hepatic failure will be high postoperatively when patient,s SRLV is less than this value.

Objective: To study the chemical constituents from the roots of Rubus parvifolius. Methods: The chemical constituents were extracted and purified by silica gel column chromatography. NMR spectra were used for structural identification. Results: Phytochemical study on the roots of R. parvifolius led to the isolation of one ceramide (1), two anthraquinones ( 2 and 3), four triterpenoids (4-7), two flavonoids (8 and 9), one fatty acid ester (10), and two sterols (11 and 12). Conclusion: Compound 1 is isolated from the plants of family Rosaceae for the first time, and compounds 2-5 are isolated from genus Rubus for the first time. Though R. parvifolius shares the same major chemical types (triterpenoid, flavonoid, and anthraquinone) with those of R. alceaefolius, a substituent of R. parvifolius, their individual constituents are different. In addition, R. parvifolius contains ceramide (1) with high concentration, while caffeoylquinic acid reported in R. alceaefolius has not been found in R. parvifolius. Furthermore, the results from our phytochemical study are consistent with the DNA phylogenic relationship between R. parvifolius and R. alceaefolius (two separated subgenera), suggesting that the substitution of the former species with the latter one in folk medicine might not be suitable.

Objective: To explore the potential Q-marker of Paeoniae Radix Alba in Danggui Sini Decoction based on fingerprint and network pharmacology. Methods: The fingerprints of Paeoniae Radix Alba decoction and Danggui Sini Decoction were established, and the law of components transfer was also defined. The "compounds-targets-pathways" network was then established to predict the potential Q-marker of Paeoniae Radix Alba through the network pharmacology. Results: The fingerprints of 15 batches of Paeoniae Radix Alba decoction and 15 batches of Danggui Sini Decoction were established, and the five chromatographic peaks were identified, they were gallic acid, albiflorin, paeoniflorin, 1,2,3,4,6-O-pentagalloylglucose, and benzoyl paeoniflorin. Through the network pharmacology analysis, the potential two active components, eight core targets and 13 key pathways were screened out, which indicated that paeoniflorin and albiflorin were preliminarily predicted to the potential Q-marker of Paeoniae Radix Alba. Conclusion: The analysis and prediction of the Q-marker in this study can provide a reference for the whole control of the Paeoniae Radix Alba quality, which can also provide the basis for the further research on the efficacy-related substance and mechanism of Paeoniae Radix Alba.

Objective: This paper aims to provide the experimental foundation for quality control of Aurantii Immaturus Fructus from different habitats by analyzing the multi-component qualitatively and quantitatively. Methods: Fingerprint pattern and QAMS were combined in this experiment, and HPLC analysis was performed on a Waters X-Brige C18 (200 mm × 4.6 mm, 5 μm) column with mobile phase composed of acetonitrile (A) -0.1% methanoic acid solution at a flow rate of 1.0 mL/min in gradient elution mode. The column temperature was maintained at 30 ℃, the injection volume was 10 μL, and the detection wavelengths were set at 283 and 330 nm. Results: The HPLC-UV fingerprint of Aurantii Immaturus Fructus from different habitats was established with 21 common peaks, 9 of them were identified as narirutin, naringin, hesperidin, neohesperidin, naringenin, hesperetin, sinensetin, nobiletin and tangeretin, and the similarity of 23 batches of samples were greater than 0.9, CA and PCA show the classification is consistent with the habitats distribution of the medicine. Then, the QAMS result showed some differences with neohesperidin to be the internal standard. Conclusion: From the perspective of composition, there are some differences in the quality of Aurantii Immaturus Fructus from different habitats, and the method of QAMS is accurate, efficient and feasible, which has obvious advantages than standard curve method and external standard method. In a word, it can be applied to quality evaluation and provides the experimental foundation for quality control of Aurantii Immaturus Fructus from different habitats.
