Ginseng saponins are a type of important active substances in the ginseng genus plants. They have notable pharmacological activities of antineoplastic, neuroprotective, and hepatoprotective activities, which have been drawn more attention to obtain minor ginsenosides by all kinds of methods. In this review, we discussed the latest progress for enrichment of minor ginsenosides by biological transformation of major ginsenosides. At the same time, we have a brief outlook of the research at bioconversion of ginseng saponins.

To study the immunopathological characteristics and differential diagnosis of hepatic angiomyolipoma(AML).Methods:Thirty-six surgically resected hepatic AML were investigated clinicopathologically and immunohistochemically with 10 antibodies.Results:Hepatic AML occurred in 21 females and 15 males,with the mean age of 41.6 years(26-60 years old).The patients with AML often had no special symptoms even had large space-occupying lesions in the liver.The diameter of AML was 2.5 cm to 14 cm(mean 6.8 cm).Histologically,AML was composed of varying heterogeneous mixture of 3 tissue components:blood vessels,smooth muscle and adipose cells.Extramedullary hemopoiesis sometimes existed.According to tissue components,AML was subcategorized into mixed type(19.4%,n=7),lipomatous type(11.1%,n=4),myomatous type(66.7%,n=24),and angiomatous type(2.8%,n=1).The epithelioid smooth muscle cells were sensitive to HMB-45(100%),SMA(100%),and CD117(66.7%) staining.Conclusion:Hepatic AML often contains smooth muscle elements,which have varied morphological features and should be carefully differentiated from hepatocellular carcinoma,mesenchymal hamartoma,and tumors with rich fat or blood vessels.Immunohistochemical staining with HMB-45 and SMA are the best available markers for the diagnosis of hepatic AML.

Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1

OBJECTIVETo investigate the effect of ulinastatin on renal function and ultrastructure changes after renal ischemia-reperfusion in rats.
METHODSAcute ischemic renal injury model was established (45 min of bilateral renal ischemia and reperfusion for 24 h). Thirty Male SD rats were randomly divided into 3 groups: sham operation group (control group or group C, without renal ischemia), renal ischemia-reperfusion group (ischemia-reperfusion group or group I, without ulinastatin), renal ischemia-reperfusion and ulinastatin intravenous injection group (ulinastatin group or group U). BUN level, serum creatinine values and renal ultrastructure were measured.
RESULTSSerum creatinine (167 +/- 39) micromol/L and BUN concentration (21 +/- 7) mmol/L in group I were significantly higher than those in group U: serum creatinine (116 +/- 13) micromol/L and BUN concentration (14.1 +/- 2.6) mmol/L (P < 0.05). The renal ultrastructure was greatly injured in group I, meanwhile, it was obviously ameliorated in group U.
CONCLUSIONUlinastatin greatly improved renal function and provides remarkable protection on renal ultrastructure after ischemia-reperfusion of kidney in rats.

Traditional Chinese medicine (TCM) dispensing is the final step of TCM used for clinical treatment, the stability of TCM dispensing is the guarantee of good clinical effect. Establishment of effect-constituent equivalence for Chinese herbal pieces based on clinical efficacy, can not only guarantee the stability of TCM dispensing, but also relate to the precision of clinical effect. This study chose Coptidis Rhizoma as the model, established effect-constituent equivalence of Coptidis Rhizoma, based on the effect-constituent index already established by our research group, and taking into consideration of homogeneity of clinical dosage and compliance of decoction, the uniformity of dispensing for different specification of Coptidis Rhizoma decoction pieces was studied. This research model was then applied to guide the specification-optimization of Coptidis Rhizoma and its clinical dispensing. The result indicated, effective constituent equivalence could reflect the fluctuation of specification, dosage and decoction to the fluctuation of efficacy; Optimized Coptidis Rhizoma decoction pieces had the characteristic of high homogeneity as for clinical dispensing, good compliance as for decoction, and high effective constituent equivalence. In conclusion, effective constituent equivalence could improve relevance of methods of TCM dispensing control to clinical effect. Preparated Superior-standard Decoction Pieces based on effective constituent equivalence was featured by good quality and a good practice of adjustable dosage, which could promote the development of TCM decoction pieces toward precision medicine.

BACKGROUNDTreatment for malignant glioma generally consists of cytoreductive surgery followed by radiotherapy and chemotherapy. In this study, we intended to investigate the effects of 2-propylpentanoic acid (VPA), a histone deacetylase inhibitor, on chemosensitivity and radiosensitivity in human glioma cell lines.
METHODSHuman glioma cell lines, T98-G, and SF295, were treated with temozolomide (TMZ) or irradiation (IR), with or without VPA (1.0 mmol/L). Then, cytotoxicity and clonogenic survival assay was performed. Cell cycle stage, apoptosis, and autophagy were also detected using flow cytometry and dansyl monocadaverin (MDC) incorporation assay. One-way analysis of variance (ANOVA) and t-test were used to analyze the differences among variant groups.
RESULTSMild cytotoxicity of VPA was revealed in both cell lines, T98-G and SF295, with the 50% inhibiting concentration (IC50) value of (3.85 ± 0.58) mmol/L and (2.15 ± 0.38) mmol/L, respectively; while the IC50 value of TMZ was (0.20 ± 0.09) mmol/L for T98-G and (0.08 ± 0.02) mmol/L for SF295. Moreover, if combined with VPA (1.0 mmol/L) for 96 hours, the sensitivity of glioma cells to TMZ was significant increased (P < 0.05). The surviving fractions at 2 Gy (SF2) of T98-G and SF295 cells exposed to IR alone were 0.52 and 0.58. However, when VPA was combined with IR, the SF2 of T98-G and SF295 dropped to 0.39 (P = 0.047) and 0.49 (P = 0.049), respectively. Treatment with VPA plus TMZ or IR also resulted in a significant decrease in the proportion of cells in the G2 phase and increased apoptotic rates as well as autophagy in T98-G and SF295 cell lines (P < 0.01).
CONCLUSIONVPA may enhance the activities of TMZ and IR on glioma cells possibly through cell cycle block and promote autophagy, and thus could be a potential sensitizer of glioma treatment.
