OBJECTIVE: The purpose of this study was to examine the symmetry and parallelism of the skeletal and soft-tissue poria by three-dimensional (3D) computed tomographic (CT) imaging. METHODS: The locations of the bilateral skeletal and soft-tissue poria in 29 patients with facial asymmetry (asymmetric group) and 29 patients without facial asymmetry (symmetric group) were measured in 3D reconstructed models of CT images by using a 3D coordinate system. The mean intergroup differences in the anteroposterior and vertical angular deviations of the poria and their anteroposterior and vertical parallelism were statistically analyzed. RESULTS: The symmetric and asymmetric groups showed significant anteroposterior angular differences in both the skeletal and the soft-tissue poria (p = 0.007 and 0.037, respectively; Mann-Whitney U-test). No significant differences in the anteroposterior and vertical parallelism of the poria were noted (p < or = 0.05; Wilcoxon signed-rank test). CONCLUSIONS: In general, the skeletal poria are parallel to the soft-tissue poria. However, patients with facial asymmetry tend to have asymmetric poria.

HPLC specific chromatograms of Poria were established, and the concentrations of 10 triterpenoids(16α-hydroxydehydrotrametenolic acid, poricoic acid B, dehydrotumulosic acid, poricoic acid A, polyporenic acid C, poricoic acid AM, 3-O-acetyl-16α-hydroxydehydrotrametenolic acid, dehydropachymic acid, pachymic acid, and dehydrotrametenolic acid) were simultaneously determined. Chromatographic analysis was conducted on a Welch Ultimate XB C_(18) column(4.6 mm × 250 mm,5 μm). Acetonitrile solution(contain 3% tetrahydrofuran)(A) and 0.1% formic acid aqueous solution(B) were used as the mobile phase with gradient elution at a flow rate of 1.0 mL·min~(-1). The column temperature was 30 ℃ and the injection volume was 20 μL. The experimental data were analyzed by the SPSS 22.0 and GraphPad Prism 7.0. The established triterpenoids fingerprints were specific, and the 10 components were well separated and showed good linearity(r≥0.999 6) within the concentration ranges tested. The mean recoveries were between 98.53%-103.8%(RSD 1.7%-2.7%). The method was specific and repeatable, and could be used for identification and quality evaluation of Poria. The results showed that the contents of 10 triterpenoids were positively correlated with each other. The contents of 10 triterpenoids of samples collected from producing areas were higher than that collected from markets. The total contents of 10 triterpenoids of samples collected from Hubei and Yunnan province were slightly higher than that from Anhui province, but the contents of samples from Anhui province were varied in smaller ranges.

Poria(Fu Ling) is a bulk traditional Chinese medicine(TCM)with a long history and complex varieties. The royal medical records of the Qing Dynasty include multiple medicinal materials of Fu Ling, such as Bai Fu Ling(white Poria), Chi Fu Ling(rubra Poria), and Zhu Fu Ling(Poria processed with cinnabaris). The Palace Museum preserves 6 kinds of specimens including Fu Ling Ge(dried Poria), Bai Fu Ling, Chi Fu Ling, Zhu Fu Ling, Bai Fu Shen(white Poria cum Radix Pini), and Fu Shen Mu(Poria cum Radix Pini). After trait identification and textual research, we found that Fu Ling Ge was an intact sclerotium, which was processed into Fu Ling Pi(Poriae Cutis), Bai Fu Ling and other medicinal materials in the Palace. The Fu Ling in the Qing Dynasty Pa-lace was mainly from the tribute paid of the officials in Yunnan-Guizhou region. The tribute situation was stable in the whole Qing Dynasty, and changed in the late Qing Dynasty. The cultural relics of Fu Ling in the Qing Dynasty Palace confirm with the archival documents such as the royal medical records and herbal medicine books, providing precious historical materials for understanding Fu Ling in the Qing Dynasty and a basis for the restoration of the processing of the Fu Ling in the Qing Dynasty Palace.

Gas chromatography/mass spectrometry, chemometric resolution method-Alternative movingwindow factor analysis that were proposed recently and the Kovats retention index were used to analyze the essential components of herbal pair Cinnamomum cassia Presl and Poria cocos (CCP-PC) and compare them with those of single herbal Cinnamomum cassia Presl (CCP). 46 and 42 essential components in essential oil of CCP and CCP-PC have been identified individually. Results shows that the number of essential components of CCP and CCP-PC were almost the same, but extractive ratioes of them have changed significantly, some of them were increased obviously, most of them were declined notably instead and even several ingredients of CCP-PC were disappeared due to CCP PC's interaction probably. The main pharmacodynamic ingredients of CCP-PC, 3-phenyl-2-propenal and Cinnamaldehyde were obviously higher contents than that of single CCP. It suggested that there exist certain interactions of the chemical ingredients in compound medicine rather than their sum effect of single medicines. There is a litter difference in quality and quantity between single medicines and pair medicines, so the application of pair medicines can expand single medicine's adaptive disease and has a good clinical referenced valuation.

With the combined applications of steam distillation, water extraction and alcohol precipitation, liquid-liquid extraction and column chromatography over macroporous resin, a splitted-fractions method of the chemical constituents of Poria cocos was established. The unoverlapping property of the fractions of P. cocos was qualitatively analysed by using principal component analysis and cluster analysis. With angle cosine, squared euclidean distance and the overlapping analysis of peak area of crude herbs, the unoverlapping property of the fractions of P. cocos was half-quantitatively analysed. The chemical components of P. cocos was divided into the fractions of polysaccharide, petroleum ether, ethyl acetate, alcohol eluate from macroporous resin and water eluate from macroporous resin. Non similarity degree among each chemical fraction was above 80% and main chemical components were identified. The established method for splitting fractions of P. cocos has good stability and repeatability and all chemical components in P. cocos could be completely divided into six fractions. It is the first time that the author half-quantitatively analyse the unoverlapping property of the chemical fractions of P. cocos.

OBJECTIVETo study the dymamic accumulation of triterpenic acids production in submerged cultivation mycelium of Poria cocos.

METHODLiquid culture method of P. cocos was established and RP-HPLC was applied to determine the contents of three main triterpenic acids dehydrotumulosic acid (DTA), 3-epi-dehydrotumulosic acid (eDTA) and polyporenic acid C (PAC) in submerged cultivation mycelium P. cocos at different culture stages and the contents were compared with cultivated P. cocos. The HPLC method is as follows, column: Plastisil ODS (4.6 mm x 250 mm, 5 microm); mobile phase: ACN/0.5% phosphate (80:20); flow rate: 1.0 mL . min-1; detective wavelength: 242 nm.

RESULTThe maximum biomass occurred at the 8th d after inoluctation, however, the contents and yield of three compounds increased till the 17th day. The contents of three compounds were 1. 2% (DTA), 0. 42% (eDTA) and 1.0% (PAC) at the 17th day after inoculation, which were significantly higher than that in cultivated material [0.2% (DTA), 0. 12(eDTA) and 0. 16% (PAC) ]. Furthermore, a correlation analysis between the content ratios of three independent compounds was carried out. The results showed that DTA negatively correlated with eDTA and PAC, with R2 of 0. 857 6 and 0. 971 7, respectively, which suggested the role of DTA as an important intermediate in the biosynthesis of triterpenic acids in P. cocos.

CONCLUSIONThe sum content of three main terpenoids in submerged cultivation mycelium P. cocos was 5. 55 times as that in cultivated material, which strongly suggested the possibility of fermentation in the production of medicinally important triterpenic acids in the future.
