ObjectiveTo study the effects of newcastle disease virus (NDV) on tumor infiltrating lymphocyte (TIL). MethodsTILs were dissociated from 6 cases of primary hepatic carcinoma. Each case was divided into 3 portions equally, and was added 20 μl NDV with HA titer of 1∶160 (NDV group), rIL2 with the end concentration of 1 000 u/ml (rIL2 group) and 0.9% sodium chloride (control group) respectively, then cultured in the condition of 37℃，5% CO2. CD3, CD4 and CD8 were assayed by flow cytometry. The contents of IL2, IFNγ and TNFβ in supernate of NDV group and control group were examined by ELISA.ResultsCoupled material revealed that CD3 and CD4 were significantly higher in NDV group than in the other two groups (P＜0.05, P＜0.01). CD8 had no significant changes in three groups. The contents of IL2, IFNγ and TNFβ in NDV group were significantly higher than those in control group (P＜0.01, P＜0.01 and P＜0.05 respectively). ConclusionNDV can activate TIL directly.
During the past 42 months, a total of 53 patients with primary hepatic carcinoma (PHC) had been treated by fine needle percutanous ethanol intratumor infiltration (group P) and ethanol infiltration combined with intrahepatoportal chemotherapy around carcinoma, using adriamycin (group PA) or using adriamycin, carboplytin mitomycin and 5-Fu (group PC) for two courses. Result showed that 16cases were complete remission and 21 cases were part remission. The overall response rate was 69.8%, with a median survival duration of 10.1 months. After clinical contrast among three groups, the response rate in PA group exceeded P and PC group and adverse reactions was lower than PC group. The authors belive that this method might be a remedial measure for patients who are unsuitable for major surgery.
Objective To evaluate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with thermotherapy for primary hepatic carcinoma (PHC), and to provide references for clinical practice and research. Methods The following databases as The Cochrane Library, PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were searched electronically, and the other sources as supplying, such as tracing related references, were also retrieved. Besides, some unknown information was also obtained by communicating with other authors. All randomized controlled trials (RCTs) on TACE combined with thermotherapy versus TACE alone were collected. The literature was screened according to inclusive criteria, data were extracted and the quality of included studies was assessed, and then meta-analysis was conducted using RevMan 5.1 software. Results A total of 17 RCTs with 907 patients were included. Meta-analysis showed that compared with TACE alone, TACE combined with thermotherapy had a significant difference in 1-year survival rate (HR=2.40, 95%CI 1.65 to 3.48, Plt;0.000 01), 2-year survival rate (HR=3.28, 95%CI 1.87 to 5.76, Plt;0.000 1), total effective rate (RR=1.59, 95%CI 1.42 to 1.79, Plt;0.000 1) and improvement rate of life quality (RR=1.79, 95%CI 1.42 to 2.25, Plt;0.000 1). The incidences of myelosuppression and alimentary canal reactions were lower in TACE combined with thermotherapy group than those in TACE alone group, but statistically significance was only found in myelosuppression (RR=0.79, 95%CI 0.69 to 0.92, P=0.001). Conclusion Compared with TACE alone, TACE combined with thermotherapy can improve long-term survival rate and short-term curative effect, ameliorate the quality of life, and tend to reduce the incidence rate of side effects. But its long-term curative effect and more comprehensive safety still needs to be further verified by more large sample and high quality RCTs.
Objective To study the efficiency of percutaneous acetic acid injection (PAI) or percutaneous ethanol injection (PEI) in the treatment of primary hepatic carcinoma (PHC). Methods Seventeen and 24 patients with PHC were treated, respectively by PAI or by PEI in our hospital. According to hepatic function test, soluble intereukin-2 receptor (sIL-2R), AFP, biopsy and size of tumor, the evaluation was made.Results Effective rate was 88.2% in PAI group and 87.5% in PEI group, respectively. There was no obvious influence to sIL-2R in serum in the two groups (Ｐ＞0.05). Obvious differences in impairment of hepatic functions between PAI and PEI groups were found (Ｐ＜0.01), it also showed that smaller amounts of acetic acid and less puncture frequency were required for the treatment than that of ethanol. Conclusion PAI is superior to PEI in the treatment of those patients who are complicated with cirrhosis or other vital disease.
Objective To explore the changes and interrelationship of serum interleukin-12 (IL-12) and T lymphocyte subset in patients with primary hepatic carcinoma (PHC). Methods Serum IL-12 level was determined by ELISA in 36 patients with PHC. The peripheral blood T lymphocyte subset was assessed with flow cytometry. The distribution and changes of T lymphocyte subset in the tumor tissue were detected by immunohistochemistry analysis. Results The numbers of the CD＋4 T cell were reduced and of the CD＋8 T cell increased either in peripheral blood or tumor tissue, and showed the trend of the ratio (T4/T8) declined progressively with the aggravation of the state with PHC. IL-12 and T4/T8 had significant interrelationship.Conclusion IL-12 is an important antitumor factor of the patients with PHC. T lymphocyte subset plays a great role in the process of antitumor.
ObjectiveTo explore the relationship between the levels of transferrin (TRF), prealbumin (PAB) and total bile acids (TBA) in serum and the loss of the hepatic reserve function in primary liver cancer (PHC) patients and the importance of the former factors for diagnosis of PHC. MethodsA total of 154 patients with PHC collected between March 2010 and February 2013 were included in our study. Based on the information of hepatic reserve function and the Child-Pugh classification standard, the patients were divided into Child-Pugh-A, B, and C groups with 67, 55 and 42 patients respectively. Another 58 healthy subjects were selected as the control group. Serum TRF, PAB and TBA levels were measured by automated chemiluminescence immunoassay, immune turbidimetric assay and enzymatic cycling respectively, and they were compared among the groups. ResultsTRF level of patients in the control group and Child-Pugh-A, B, and C groups was respectively (2.574±0.214), (1.618±0.135), (0.988±0.121), and (0.314±0.107) g/L, with significant differences among the groups (P<0.05). PAB level of patients in four groups was respectively (269.32±37.29), (165.22±21.01), (123.24±31.15), and (83.66±19.74) mg/L, with significant differences among the groups (P<0.05). TBA level in the above four groups was respectively (9.16±2.48), (65.13±4.25), (133.62±8.44), and (250.73±21.59) μmol/L, and there was also significant differences among the groups. A positive correlation between serum TRF and PAB was found (r=0.927, P<0.001), and negative correlations between serum TBA level and serum TRF and between TBA and PAB were found (r=-0.454, P<0.001; r=-0.432, P<0.001, respectively). ConclusionSerum TRF, PAB and TBA levels are closely related to the hepatic reserve function in PHC patients, and they can be used as an important indicator for PHC diagnosis.
