This study was aimed to carry out pharmacological research on the hemostatic activity and mechanism of Yi medicine Ma-Bu (Paris polyphylla Smith var stenophylla Franch.). One kind of C27 steroidal saponin from P. polyphylla Smith var stenophylla Franch. was isolated and identified as Paris saponin H (PSH). The effect of PSH on the index of bleeding time (BT), prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB) of mice were measured. The results showed that PSH have significant hemostatic activity by shortening BT. The effect of PSH on shortening PT and APTT of mouse was not significant. However, the FIB was enhanced significantly after treatment with PSH. It was concluded that PSH had no significant promoting effect on the extrinsic coagulation pathway (ECP) or the intrinsic coagulation pathway (ICP). The enhancement of FIB may be a pathway for the effect of hemostatic activity by PSH.

Cyclophilin A (CypA) is found to be highly expressed in different kinds of tumor cells,which could regulate the occurrence and development of many kinds of tumor through multiple signal transduction pathways such as inducing the formation of inflammatory carcinoma,accelerating the transcription cycle of tumor cells,promoting the invasion and metastasis of tumor cells,inhibiting the apoptosis of tumor cells and reducing the sensitivity of tumor cells to chemotherapy drugs.It suggests that CypA might be considered as a kind of oncogene,which is expected to be a novel target for tumor treatment.

ObjectiveTo study the potential quality marker (Q-marker) of Tinosporae Radix associated with efficacy of "relieving sore throat" based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS), multivariate statistical analysis (MSA), and network pharmacology. MethodUPLC-Q-TOF-MS was used to identify the main chemical components in 18 batches of Tinosporae Radix. On this basis, principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were employed to screen out the main marker components that caused differences between groups. Moreover, network pharmacology technology was applied to predict the potential "sore throat-relieving" components, and the molecular docking between the common components resulting from MSA and network pharmacology and the core targets was carried out to verify the marker components. ResultA total of 17 compounds, including alkaloids, diterpenoid lactones, and sterols, were identified by UPLC-Q-TOF-MS. Five main differential components were found by MSA: Columbamine, jatrorrhizine, palmatine, menisperine, and columbin. Network pharmacology analysis yielded six compounds: tetrahydropalmatine, palmatine, menisperine, fibleucin, neoechinulin A, and columbin which were selected as potential "sore throat-relieving" components of Tinosporae Radix. They may relieve sore throat by acting on interleukin-6, epidermal growth factor receptor, prostaglandin G/H synthase 2, matrix metalloproteinase-9, proto-oncogene tyrosine-protein kinase Src and other targets, and regulating Hepatitis B, influenza A, human T-cell virus infection, human cytomegalovirus infection, coronavirus disease-2019, and other signaling pathways. The common active components in Tinosporae Radix resulting from MSA and network pharmacology analysis were palmatine, menisperine, and columbin, which had high binding affinity with six core targets and can be used as the Q-marker components of Tinosporae Radix in "relieving sore throat". ConclusionThis study predicts the "sore throat-relieving" Q-marker of Tinosporae Radix, which lays a basis for developing the quality standard of Tinosporae Radix based on the efficacy and improving the quality evaluation system of the medicinal.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.
