Inhibitory effect of asiatic acid on human liver carcinoma cells via cell cycle blockage and apoptosis induction / 中国肿瘤生物治疗杂志

@# Objective: To investigate the inhibitory effect of asiatic acid (AA) on malignant biological behaviors of human liver cancer cells and to explore the mechanism. Methods: Human liver cancer cell line (Huh7) was used as research subject, and treated with different concentrations of AA (0, 5, 10, 25, 50, 100 μmol/L) in vitro. The effect of AA on cell proliferation was determined by CCK-8 and EdU assay; the apoptosis and cell cycle distribution were detected by flow cytometry, while the expressions of apoptosis-related proteins (AKT, P-ERK 1/2 , p38, cleaved-caspase3, cleaved-caspase9, BAX, Bcl-2, AKT, ERK, p38, pro-caspase 3 and pro-caspase 9) were examined by WB. Results: AA could inhibit the proliferation of Huh7 cells in a dose- and time-dependent manner (all P<0.05). After being incubated with 10 μmol/L AA for 24 h, the proliferation of Huh7 cells was significantly inhibited (P<0.05), the apoptosis rate was significantly increased (P<0.05), and cell cycle was arrested in G1 phase (P<0.05).AAinduced p-p38 expression, but inhibited the expression of p-AKT and p-ERK in a dose-dependent manner (all P<0.05). In addition, as the concentration of AA increased, the levels of cleaved-caspase 3, cleaved-caspase 9 and BAX increased, while the level of Bcl-2 decreased (all P<0.05). Conclusion:AAinhibits the proliferation of human liver cancer cells and promotes its apoptosis, which is associated with the MAPK and PI3K/AKT pathways.

Evaluation of the Efficacy of Subcostal Transversus Abdominis Plane Block for Patients Undergoing Open Liver Carcinoma Resection / 中山大学学报(医学科学版)

@#【Objective】To evaluate the efficacy of three different methods of subcostal transversus abdominis plane（TAP）block for patients undergoing open liver carcinoma resection.【Methods】A total of 60 adult patients，undergoing elective open liver carcinoma resection through a“reverse L”incision below the rib bow，were enrolled. The subjects were randomly divided into three groups（20 cases in each），including Group A，B and C，according to the position of local anesthetic injection. All patients underwent ultrasound- guided bilateral subcostal TAP block under local anesthesia. The TAP injection was injected at the middle line of the clavicle in Group A；Two separate injections were at the parasternal line and at the anterior axillary line in Group B；Multiple injections were proformed between the anterior median line and the middle axillary line in Group C. After completion of TAP block，the onset time，duration，blocking extent，hemodynamics and abdominal muscle thickness were evaluated. The operating time of TAP block and incidence of complications were recorded.【Results】The blocking extent of Group B or Group C was greater than that of Group A（P < 0.05），with no significant difference between Group B and Group C. The duration of TAP block in Group B or Group C was longer than that of Group A，while the onset time was not significantly different between the three groups. The mean arterial pressure and heart rate during laparotomy were higher than the base value in Group A，while there were no evident changes in Group B and Group C. The rectus abdominis became thinner after TAP block in all patients，but there was no significant difference in muscle thickness change among the three groups. The operating time of TAP block in the three groups was （8.4±1.9），（13.8±3.1），（23.3±4.2）min，respectively，with significant difference between any two groups（P < 0.05）. None of the patients enrolled showed such complications as local anesthetic poisoning，abdominal wall hematoma，nerve injury， abdominal viscera injury，and puncture point infection.【Conclusion】The outcome of subcostal TAP block for patients undergoing open liver surgery is related to injecting position of anesthetics. Two- point-injection method is superior to one- point-injection method or multiple-point-injection method，for adequate analgesic extent as well as less operating time.

Study on proliferation and apoptosis of paclitaxel to liver carcinoma cell line HepG2 and hepatocytes in vitro / 中国药理学通报

Aim To explore the influence of paclitaxel in the proliferation and apoptosis of liver carcinoma cell line HepG2 and hepatocytes in vitro. Methods HepG2 cells and hepatocytes were divided into negative control group and different concentrations(5, 10, 20, 40, 80 μg·L-1) paclitaxel groups. The inhibitory rates of proliferation of HepG2 cells and hepatocytes treated by different concentrations of paclitaxel for 24, 48 and 72 hours were assessed by MTT method. The apoptotic rates and cell cycle of HepG2 cells and hepa-tocytes treated by different concentrations of paclitaxel were measured by flow cytometry after Annexin V/PI staining. Results MTT results showed that paclitaxel inhibited the proliferation of HepG2 cells and hepato-cytes in a concentration-dependent manner ( P <0.05) . Paclitaxel induced morphological changes of apoptosis in the HepG2 cells and hepatocytes by using Hoechst 3328 staining. The flow cytometry results showed the cell cycle changes of HepG2 cells and hep-atocytes treated by different concentrations of paclitaxel for 24 h. Compared with negative control group, the percentages of HepG2 cells and hepatocytes in G2/M phase increased ( P < 0.05 ) . The G2/M block in-creased with the drug concentration. With the increase in Paclitaxel, G2/M phase significantly increased( P<0.05), G0/G1phase decreased(P <0.05), but no significant change occurred in S phase ( P >0.05 ) . Meanwhile, paclitaxel induced apoptosis in HepG2 cells and hepatocytes. However, the apoptotic rate of HepG2 cells induced by paclitaxel was significantly higher than that of hepatocytes, and the apoptotic rate of HepG2 cells increased gradually with the increase of paclitaxel concentration. Conclusion Paclitaxel can inhibit the proliferation of HepG2 cells and hepato-cytes, which may be achieved by inducing apoptosis and cell cycle arrest in G2/M phase.

Objective To study the clinical treatment and prognosis of de novo liver cancer following renal transplantation.Methods The clinical data of 15 patients who developed de novo liver cancer after renal transplantation carried out prior to treatment of liver cancer at the First Center Hospital of Tianjin between June 2006 and June 2016 were retrospectively studied.These patients were diagnosed to have liver cancer ranging from 23 to 98 months after renal transplantations,with an average of (42.5 ± 29.7) months.Two patients were diagnosed within 2 years,7 within 5 years,and 6 over 5 years after renal transplantation.Results Three patients underwent transcatheter arterial chemoembolization (TACE) and 12 patients underwent surgical resection which included right/left hemihepatectomy (n =5),hepatic segment resection (n =4),and tumor enucleation (n =3).Postoperative histopathology confirmed hepatocellular carcinoma in 8 patients,cholangiocarcinoma in 1 patient,and mixed liver cancer in 3 patients.Among the 12 patients who initially underwent'curative'surgery,3 patients died from recurrent cancer 8,16,25 months after surgery,respectively.The remaining 9 patients were still alive with a follow-up which ranged from 0.6 to 65-month.The 3 patients who underwent TACE were alive for 4,7 and 13 months,respectively.Conclusions De novo liver cancer were usually asymptomatic and had a rapid onset.The optimal clinical management which includes early diagnosis,appropriate therapy with immunosuppression and renal function preservation can result in good long-term survival.

Study on anti-hepatoma effect of ginsenoside Rh2 and mechanism of degradation of β-catenin through activating GSK-β / 中草药

Objective: To investigate the anticancer effect and the mechanism of ginsenoside Rh2 on animal model of HepG2 liver carcinoma. Methods: HE staining was used to observe cell morphology. Immunohistochemical staining was used to detect the expression of GSK-3β, β-catenin, and MMP-3 in isolated single cells. The activity of GSK-3β was checked by ELISA kit. The expression levels of GSK-3β, β-catenin, Bax, Bcl-2, CyclinD1, and MMP-3 genes were measured by qRT-PCR. The expression of β-catenin and GSK-3β proteins were determined by Western blotting. Results: HE staining showed that the nucleus was atypia and account for a large proportion of the whole cell in HepG2 group and HepG2-β-catenin group. But nucleus atypia in HepG2-β-catenin group was more obvious. Condensation nuclei and a lot of broken cells were observed in HepG2-β-catenin + ginsenoside Rh2 group and HepG2 + ginsenoside Rh2 group. However, condensation nuclei and broken cells in HepG2 + ginsenoside Rh2 group were more obvious. Immunohistochemical results indicated the expression of GSK-3β increased, while β-catenin and MMP-3 expression decreased in HepG2-β-catenin + ginsenoside Rh2 group, compared with HepG2-β-catenin group. The expression of β-catenin and MMP-3 in HepG2 + ginsenoside Rh2 group was lower than that in HepG2-β-catenin + ginsenoside Rh2 group, while GSK-3β was no significant difference. The ELISA results indicated that the activity of GSK-3β was increased in HepG2 + ginsenoside Rh2 group and HepG2-β-catenin + ginsenoside Rh2 group. Compared with HepG2-β-catenin + ginsenoside Rh2 group, the expression of Bax gene in HepG2 + ginsenoside Rh2 group increased significantly, and the expression levels of Bcl-2, CycliD1, and MMP-3 genes were also significantly lower, the difference was statistically significant (P <0.01). The Western blotting results showed that compared with HepG2-β-catenin + ginsenoside Rh2 group, the expression of β-catenin protein in HepG2 + ginsenoside Rh2 group was also significantly lower, the difference was statistically significant (P < 0.01). Conclusion: In vivo experiment shows that weight of tumor is decreased by ginsenoside Rh2 through activating GSK-3β to degrade β-catenin and could inhibit the ability of HepG2 cells metastasis.

Prognostic factors for patients with bone metastasis from primary liver carcinoma:a report of 55 cases / 实用肿瘤学杂志

Objective To improve the clinical diagnosis and prognosis of the treatment of primary liver carcinoma with bone metastasis.Methods A retrospective study on diagnosis and treatment of bone metastasis from 55 cases of primary liver carcinoma was developed.Survival rates were calculated by Kaplan-meier meth-od,univariates analysed by Log-rank and multivariates analysed by Cox regression.Results The 1-,2-and 3-year cumulative survival rates of the cases from primary liver carcinoma were 54.5%,25.5%and 16.4%re-spectively.The mediate survival time was 13 months.And the cases with bone metastasis were 23.6%,10.9%and 1.8%respectively.The mediate survival time was 5.5 months.Factors such as metastasis to other organs,liv-er function,and the combined modality therapy were independent prognostic factors.While number of bone metas-tasis,AFP level and number of liver cancer had no significant relations with the survival rate.Conclusion The prognosis of bone metastasis from primary liver carcinoma is poor.It is important to take emphasis on combined mo-dality therapy,which may be benefit on reducing the symptom,improving the quality and prolong the life span.

Imaging characteristics and intervention therapy for hepatic artery-portal vein shunts in patients with primary liver carcinoma / 中国肿瘤临床

Objective:To investigate the onset of hepatic artery-portal vein shunts (HAPVS) in primary liver cancer (PLC) pa-tients through digital subtraction angiography (DSA) and to devise a suitable strategy for treating both lesions and shunt tracts. In the process, the therapeutic effect on such patients can be enhanced. Methods:A total of 769 PLC patients who accepted transarterial che-moembolization (TACE) were analyzed retrospectively. We examined the image characteristics of 112 cases with HAPVS based on shunt type. For patients with middle or severe fistula, we initially attempted to overpass the fistula. Then, we either embolized the tumor lesions or merely provided chemotherapy to the patients. For patients with mild peripheral fistula, we embolized the tumor and fistula si-multaneously. Then, the accompanying arterial-vein shunt and portal vein tumor thrombus (PVTT) were handled at the same time. Re-sults: DSA findings showed that portal veins were observed in the early stage of angiography. A total of 52 of the 112 cases with HAPVS involved mild shunts, 34 exhibited moderate shunts, and 26 reported severe shunts. Among these cases, 31 involved central-and central peripheral-type artery-portal vein fistula, whereas 81 involved peripheral-type artery-portal vein fistula. Seven cases were examined in combination with hepatic artery-liver vein shunts, and 50 cases were investigated in conjunction with PVTT. Tumor embo-lization was successful in 101 cases (90.1%). Moreover, catheters successfully overpassed shunt tracts and embolized the tumors in 48 cases (42.9%). Shunt tracts were successfully closed in 74 cases (66.1%), and no serious complication was observed. Conclusion:Pe-ripheral-type artery-portal vein fistula and mild-to-moderate shunts were easier to close than central-type artery-portal vein fistula and severe shunts were. Tumor embolization and shunt closure were successful in most patients. Therefore, TACE is a safe and reliable method for treating HAPVS in PLC.

The 1-, 3-, 5-year accululative survival and recurrence rate in each group were compared. Results The accumulative 1-, 3-, 5-year survival rates were 93.3%, 71.9%, 57.2% for group A; 86.7%, 46.5%, 38.8% for group B; 95.7%, 78.3%, 72.1% for group C,respectively. The 1-, 3-, 5-year recurrence rates were 30. 3% , 49. 7%, 68. 6% for group A; 39. 3% , 58. 7% , 79. 3% for group B; 7. 0% , 12. 1% , 12. 1% for group C,respectively. There was a highly significant difference between groups A, B and C in the survival rates and the recurrence rates. The 5-year survival rate was significantly higher for group C than group A and group B (P<0. 01, P<0. 001), and the recurrence rate of 1, 3, 5-years were significantly lower for group C than for group A and B (P<0. 001). Conclusion Liver transplantation was the most effective therapy for the early-intermediate stage primary liver cancer.
