ObjectiveTo analyze the effects of new integration processing method in producing area and traditional method on the composition and pharmacological action of Polygoni Multiflori Radix Praeparata（PMRP）， and to illustrate the advantages of toxicity reducing and efficacy enhancing of the decoction pieces prepared by the new method. MethodFresh Polygoni Multiflori Radix（PMR） was taken from Dao-di producing area， and was processed by new integration processing method in producing area（steaming with black bean juice under pressure of 0.1 MPa and temperature at 120 ℃ for 10.5 h） and traditional method（steaming with black bean juice under water for 36 h）， respectively. Samples were collected during the processing process of the two methods， For new method， the samples were collected at 0.5， 3， 5.5， 8， 10.5 h， separately. For traditional method， the samples were collected every 4 h. High performance liquid chromatography（HPLC） was used to establish fingerprint and identify common peaks， the content of polysaccharides was determined by anthrone-sulfuric acid colorimetry at 627 nm， and the contents of anthraquinones and stilbene glycosides in different processed products were determined according to the methods under the item of determination of PMR and PMRP in the 2020 edition of Chinese Pharmacopoeia. In pharmacological experiments， 90 SD rats were randomly divided into 9 groups with 10 in each group（half of male and half of female）， including the blank group， and raw products， 24 h processed products under atmospheric pressure， 30 h processed products under atmospheric pressure， 8 h processed products under high pressure groups with low and high dosages（4.125， 16.5 g·kg^-1）. Rats were given the drug by gavage for 29 d with once a day， blood was collected from the abdominal aorta after the last administration， and the serum was isolated， the body mass and liver mass of rats were weighed and the organ index was calculated. The pathological change of liver tissue was observed by hematoxylin-eosin（HE） staining， and biochemical methods were used to detect the contents of aspartate aminotransferase（AST）， alanine aminotransferase（ALT）， alkaline phosphatase（ALP）， γ-glutamyltransferase（GGT）， lactic dehydrogenase（LDH） in serum which used as liver function indicators and the levels of superoxide dismutase（SOD）， malondialdehyde（MDA）， glutathione peroxidase（GSH-Px） in brain tissues which used as oxidation indicators. ResultA total of 14 common peaks were identified in the fingerprint of PMR， PMRP prepared by new method and traditional method， and three of the peaks were designated as stilbene glycoside， emodin and emodin methyl ether， respectively. The characteristic peak areas of each processed products changed significantly from 0 min to 25 min， indicating that different processing methods had an effect on the contents of components with high polarity in PMRP， and the trend of the changes of the two methods was similar， with the higher degree of change in the new method. The determination results showed that compared with the traditional method， the content of polysaccharide（a kind of beneficial component in PMRP obtained by the new method） significantly increased， while the contents of stilbene glycoside and bound anthraquinone（liver-damaging ingredients） significantly decreased. The pharmacological results showed that compared with the blank group， AST and LDH levels of male rats in the low and high dose groups of 24 h processed products under atmospheric pressure and AST level of male rats in the low and high dose groups of 8 h processed products under high pressure were significantly reduced（P<0.05， P<0.01）， while compared with the raw product groups with the same dose， AST and LDH levels of male rats in the low dose group of 30 h processed products under atmospheric pressure were significantly reduced（P<0.05， P<0.01）， the AST levels of male rats in the low and high dose groups of 8 h processed products under high pressure were significantly decreased（P<0.01）， and there was no statistical significance in the differences of biochemical indexes of female rats in each administration group as compared with those of the blank group. ConclusionThe new integration processing method in producing area of PMRP can reach the quality of relevant regulations in 8 h. The processed products obtained by this method have more advantages than the traditional method in terms of toxicity reducing and efficacy enhancing， and energy saving to avoid the loss of ingredients， which can provide ideas for the production of high-quality decoction pieces of PMRP， and the integration processing method in producing area of other roots and rhizomes of traditional Chinese medicines.

ObjectiveTaking the oligosaccharides in Rehmanniae Radix（RR） as the research object， the content determination method based on high performance liquid chromatography-evaporative light scattering detection（HPLC-ELSD） and thin layer chromatography（TLC） identification method were established to explore the content and distribution of oligosaccharides in different RR herbs and decoction pieces. MethodA total of 10 batches of fresh and raw RR， 12 batches of RR decoction pieces and Rehmanniae Radix Praeparata（RRP） were collected. A TLC identification method for fructose， sucrose， manninotriose， raffinose and stachyose in RR was established by using silica gel G thin-layer plates with ethyl acetate-water-anhydrous formic acid-glacial acetic acid（12∶6∶5∶4） as the developing agent and 10% sulfuric acid-ethanol solution as chromogenic agent. A HPLC-ELSD was used to determine the contents of fructose， glucose， sucrose， melibiose， raffinose， manninotriose and stachyose in different RR herbs and decoction pieces. Then principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） were used to analyze the contents of 7 kinds of saccharides in RR herbs and decoction pieces， and the differential components were screened with the value of variable importance in the projection（VIP）>1. ResultThe results of TLC identification showed that fresh RR， raw RR and its decoction pieces showed spots of the same color on the corresponding positions with the control products of stachyose， raffinose and sucrose， while the TLC of RRP showed spots of the same color at corresponding positions to manninotriose and fructose controls. The results of methodological investigations of 7 analytes met the requirements of determination. Only glucose， sucrose， raffinose and stachyose were detected in 10 batches of fresh RR and 10 batches of raw RR herbs， the average contents of which were 0.84%， 4.62%， 2.42% and 57.90% in fresh samples， while those were 3.16%， 9.36%， 7.05% and 38.10% in raw samples， respectively. In 12 batches of RR decoction pieces， the contents of the above seven sugars（fructose， glucose， sucrose， melibiose， raffinose， manninotriose and stachyose） were 1.68%， 4.27%， 9.96%， 0.53%， 6.85%， 3.05% and 37.52%， respectively. In 12 batches of RRP， the contents of the above seven sugars were 10.62%， 11.01%， 1.25%， 3.35%， 1.12%， 28.16% and 6.39%， respectively. The results of multivariate statistical analysis showed that fresh RR， raw RR and RRP could be distinguished from each other by the contents of the 7 sugars， and the main differential components were stachyose， sucrose， raffinose and manninotriose. ConclusionIn terms of oligosaccharides， the contents and types of saccharides in different herbs and decoction pieces of RR are quite different， and the TLC identification method based on this can be used to distinguish raw RR from RRP， which can lay a foundation for improving the quality standard of RR and developing and applying oligosaccharides in different processed products of RR.

Objective:To investigate the effect and mechanism of bone marrow mesenchymal stem cells (BMMSCs) on liver transplantation with 50% reduced-size in rat models.Methods:For 40 normal male Brown Norway(BN) and Lewis rats weighing 210-250 g were included respectively to generate the acute rejection models following 50% reduced-size liver transplantation in rats. The recipients were divided into BMMSCs group ( n=20) and normal saline group ( n=20). Healthy male BN rats were used to prepare BMMSCs. Transplanted liver tissues were collected at 0h, 1d, 3d, 7d post the transplantation for further analysis. Pathological changes and the extent of rejection were evaluated under the light microscope. The levels of microtubule-associated protein 1 light 3 (LC3) and autophagy regulator Beclin-1 proteins were detected by immunohistochemical analysis and Western blotting. Results:Rejection activity indices of the normal saline group at 0d, 3d, 7d after the surgery were (2.33±0.58), (4.00±0.00), (6.33±0.58). The BMMSCs group were (2.10±0.58), (3.73±0.58), (5.67±1.15), which was decreased comparing with normal saline group, difference was statistically significant ( P<0.05). On the 1d, 3d, 7d after the transplantation, compared with normal saline group, expression of autophagy-related proteins LC3 and Beclin-1 in BMMSCs group was increased ( P<0.05). Conclusions:It showed that autophagy has an effect on the protection of BMMSCs liver graft of rats.

Objective To explore the effects of the interfacial debonding caused by water environment in the mouth and the interfacial defects between the crown and cement on stress distributions in all-ceramic crowns. Methods The three-dimensional solid model of lithium disilicate CAD/CAM crowns for the first mandibular molar was established. Seven debonding states between inferior surface of the crown and top surface of the cement (Stage 1-7) as well as two interfacial defects (Case I and II) were defined in finite element software ABAQUS. The bottom of nine models was completely constrained. For stress calculation, the 600 N vertical load was applied at occlusal surface via an analytical rigid hemisphere with the diameter of 5 mm. Results Under occlusal vertical load, the stress on interior of the crown and top surface of the cement was mainly distributed at the boundary of the debonding areas and margin of the defects. The first principle stress on interior of the crown did not exceed its ultimate tensile strength, but the maximum tensile stress of the cement exceeded its ultimate tensile strength, leading to cohesive failure in the cement. Conclusions The axial wall played a critical role in maintaining the principal tensile stress of the crown at a lower level. The defects at bonding interface between the crown and cement had a more significantly impact on load capacity of the crown than the increase in debonding areas. In order to improve load bearing capacities of all-ceramic crowns, attention should be paid to avoid defects in clinical prosthodontic practices.
