Objective To explore the quality markers of Puerariae Lobatue Radix;To predict its"efficacy component group"with alcohol detoxification and liver protection effects.Methods Fingerprints of 26 batches of Puerariae Lobatue Radix samples from different origins in China was established.Multivariate statistical analysis was employed to identify quality markers,while network pharmacology and molecular docking were used to predict the potential"efficacy component group".Results UPLC fingerprint analysis calibrated 11 common peaks.Clustering analysis classified 26 batches of samples into 3 categories,and 7 quality markers were ultimately screened through multivariate statistical analysis,including mirificin,puerarin,puerarin-6''-O-xyloside,3'-methoxypuerarin,ononin,genistin and daidzin.Network pharmacology revealed that all 7 markers interacted with targets related to alcohol-associated liver disease,identifying 19 core targets such as TNF,CASP3,BCL2,MMP9,IL2,and 93 signaling pathways involving IL-17 and PI3K-Akt signaling pathways.Molecular docking demonstrated strong binding affinity between the 7 markers and target proteins,with binding energies<-5 kcal/mol.Conclusion The"efficacy component group",main targets and signaling pathways predicted in this study can provide support for the research on the mechanism,material basis and quality control of the alcohol detoxification and liver protection effects of Puerariae Lobatue Radix.

Objective To investigate the effects of acivicin on HepG 2 cell apoptosis and the effects of acivcin with cis diaminedichloroplatinum (CDDP) on HepG 2 cell apoptosis and on production of intracellular ROS. Methods HepG 2 cells were treated with acivcin, CDDP, and acivicin combined with CDDP. The cytotoxicity was measured by MTT assay. Flow cytometry was used to detect the intracellular ROS, and the rate of apoptosis was determined by TUNEL assay. Results The concentration of acivicin to cause HepG 2 IC 50 was 1.4 mmol/L, and CDDP was 67 ?mol/L. Significant increases in intracellular ROS content were observed in HepG 2 cells 24 h after treatment with acivicin (1.4 mmol/L), CDDP (67 ?mol/L), or acivicin (1 4 mmol/L) plus CDDP (67 ?mol/L), especially with acivicin (1 4 mmol/L) plus CDDP (67 ?mol/L). HepG 2 cell apoptotic rates induced by acivicin (1 4 mmol/L) at 24, 48, and 72 h were (16 3?3 5), (27 9?4 3), (47 2?3 0), respectively, and a significant difference was observed compared to that of control group ( P

Objective To observe the dynamic changes of P 53 , C myc, Bax, Bcl 2, and NF ?B in surviving HepG 2 cells under the continuous stress of cisplatin for the investigation of the potential role in the resistance of HepG 2 cells to cisplatin. Methods The apoptosis of HepG 2 cells and changes of the apoptosis associated factors including P 53 , C myc, Bax, Bcl 2, and NF ?B in the surviving HepG 2 cells were detected by immunohistochemical and RT PCR assays. Results No obvious change of P 53 and C myc was found in the surviving HepG 2 cells under cisplatin stress, but persistent increase of Bcl 2 and decrease of Bax and a continuous increase of Bcl 2/Bax ratio were found. Markedly positive expression of NF ?B mRNA was found at 7 d after the stress of cisplatin. Conclusion The mechanisms of the surviving HepG 2 cells under continuous stress of cisplatin may be associated with the increase in Bcl 2 and decrease in Bax, specially the continuous increase in Bcl 2/Bax ratio, while the positive NF ?B mRNA expression may be associated with the later events after HepG 2 cell survive.

OBJECTIVE:To study the effects of Acivicin or/and cisplatin on the apoptpsis of HepG2 and expression of Bcl-2,c-myc and p53.METHODS:Acivicin and cisplatin were used to treat cultured HepG2 cell line separately or in combination.The cytotoxicity was measured by MTT assay,the apoptosis by TUNEL assay and relevant regulator genes by immunohistochemical SP method.RESULTS:Acivicin in concentrations of 0.28,0.56,0.84,1.12 and 1.40mmol/L,the apoptosis rates of HepG2 were (3?1.25)%,(3.7?2.0)%,(10?1.25)%,(17.4?4.5)%and (16.9?3.5)%respectively.Acivicin in concentration of 1.4mmol/L,the apoptosis rates at 24,48 and 72h were(16.9?3.5)%,(27.9?4.3)%and (47.2?3.0)%respectively,which was significantly different from control group.The apoptosis rate of HepG2 induced by cisplatin(67?mol/L)was (73.4?1.5)%at 24h.The apoptosis rate of HepG2 induced by Acivicin(1.4mmol/L)plus cisplatin(67?mol/L)was(94.7?0.5)%at 24h,which was markedly higher than those induced by Acivicin or cisplatin alone.The expressions of Bcl-2,c-myc and p53 in all groups were increased comparing with those in control group.CONCLUSION:This study indicates that the apoptosis of HepG2 induced by Acivicin was in a dose-dependent and time-dependent manner.When Acivicin and CDDP used simultaneously,the effect of CDDP on HepG2 apoptosis was enhanced greatly.

FDP/FIP (88.8%), respectively; (3) The diagnostic positivity of combination assay was 80.0% in low or negative AFP producing HCC, while 95.7% in those with elevated AFP. Our data suggested that the combination assay of serum tumor enzyme markers was valuable in the diagnosis of HCC, especially in low or negative AFP HCC patients

Suerm monoamine oxidasa isoenzymes (MAOi) were determined in 105 cases of liver disea ses and 49 normal controls.MAOi were separated into 3 bands (I. Ⅱ.Ⅲ) by polyacrylamide gel elcctrophoresis. The results revealed that MAOi Ⅲ% was increased in chronic liver diseases, especially in liver cirrhosis. Our findings suggest that serum MAOi determination is more sensitive than serum albumin, MAO, ChE, and ADA determinationsin in the early diagnosis of liver cirrhosis
