Objective To investigate the value of Habib 4X in hepatic resection. Methods The clinical outcome of 21 patients with liver disease who received liver resection at the Tianjin Third Central Hospital from November 2009 to April 2010 were retrospectively evaluated. All the operations were carried out by using Habib 4X. Results All patients received hepatectomy, including right hepatectomy in three patients, left hepatectomy in one patient, multiple segmentectomy in nine patients, single segmentectomy in seven patients and partial liver resection in one patient. All tumors were reseeted completely. The mean operation time was (50±25) minutes and the mean blood loss was(129±117)ml. No patient was transferred to ICU. Three patients were complicated with bile leakage, one with lymphatic leakage and four with pleural effusion, and they were cured by non-surgical treatment. There were no patients with postoperative hemorrhage, incision infection or hepatic failure. No mortality was observed. The mean postoperative hospital stay was(19±14)days. Conclusions Radiofrequency energy was applied along the margins of the tumor to create zones of necrosis before resection with a scalpel, offering hepatobiliary surgeons an additional method for performing liver resections with minimal blood loss, low morbidity and mortality rates. As for malignant tumors, minor or major liver resection assisted by Habib 4X is safe, and it can reduce the chance of positive incisal margin.

OBJECTIVETo examine the correlation between p65 expression and the metastasis and prognosis in tongue carcinoma.
METHODSThe immunohistochemical expression of p65 was examined in 50 cases of tongue carcinoma, and the clinical and histopathologic records were retrospectively analyzed.
RESULTSOverexpression of p65 in cytoplasma and nucleus was found in 64% cases of tongue carcinoma. There was significant difference of p65 expression among different TNM stages, and the higher expression rate of p65 was found in higher stages. Overexpression of p65 was also related to lymph node metastasis. Significantly greater increase in expression levels of p65 was found in the metastatic cases (n = 22) compared to the nonmetastatic cases (n = 10). However, there was no significant difference of p65 expression among different histopathologic grading. The 5-year survival rate of p65 positive and negative group was 59.3% and 88.9% respectively, and there was significant difference in Kaplan-Meier survival curve (chi2 = 5.6, P < 0.05).
CONCLUSIONThe results suggest that the expression of p65 was important to predict the metastasis and prognosis in tongue carcinoma.

OBJECTIVETo explore the therapeutic efficacy and safety of batroxobin in patients with primary hepatic carcinoma (PHC) and the advantages of transcatheter arterial perfusion of batroxobin combined with transcatheter arterial chemoembolization (TACE).
METHODS40 patients with PHC were randomized into experimental group (transcatheter arterial perfusion of batroxobin combined with TACE treatment, 20 patients) and control group (TACE alone group, 20 patients). The patients were followed up and the data were recorded, compared and analyzed.
RESULTS(1) Compared with the control group, the FIB level in the experimental group was significantly decreased at the first month after treatment (P < 0.05). (2) The baseline of the tumor was shortened in both groups after the treatment. There was a significant difference between the two groups at different time intervals (P < 0.05). (3) After the treatment, there was a significant difference of PFS levels between the two groups (t = 2.877, P < 0.05).(4) The incidence of metastasis were 5.0% (1/20) in both groups at 6 months after treatment, and that after one year was 10.0% (2/20) in the experimental group and 25.0% (5/20) in the control group. However, the difference was not significant (chi(2) = 0.693, P > 0.05).
CONCLUSIONBatroxobin can rapidly and effectively decrease the FIB level. Therefore it may be used as an effective and safe adjuvant drug for the the treatment of primary hepatic carcinoma. Transcatheter arterial perfusion of batroxobin combined with TACE therapy has advantages in comparison with TACE alone. It could be taken as a new therapeutic regimen in the PHC treatment.

OBJECTIVETo examine the relationship between NF-kappaB signal transduction way and the sensitivity of Tca8113 carcinoma cell to Pingyangmycin chemotherapy.
METHODS2 mg/L antisense p65 oligodeoxynucle-otides (5'-GAACAGTTCGTCCATGGCCG-3') was transfected into Tca8113 cells through Lepofectin vectin, then the cells were treated with 8 mg/L Pingyangmycin. After 3 h and 6 h, the expression of p65 in nucleus was studied with immunohistochemical methods and Western blot analyses. After 48 h, the inhibitory rate of cell growth was detected with MTT assay.
RESULTSThe NF-kappaB/p65 signal transduction way in Tca8113 cells was activated after treated with Pingyangmycin. But the transfection of antisense p65 oligodeoxynucle-otides inhibited the activation of the signal transduction, the p65 expression in nucleus was decreased significantly (P < 0.05) at 6 h, and the inhibitory rate of cell growth was increased significantly (P < 0.05) at 48 h.
CONCLUSIONThe results suggested the chemotherapeutic sensitivity of Tca8113 carcinoma cell to Pingyangmycin was improved by the inhibition of NF-kappaB/p65 signal transduction.

OBJECTIVETo investigate the effects of different X-ray doses on the expression of nuclear factor-kappaB (NF-kappaB) P65 in human oral squamous cell carcinoma cell (OSCC) line and the relationship between NF-kappaB P65 and radiation-induced OSCC cell line apoptosis.
METHODSThe squamous cell carcinoma of Tca8113 cell was cultivated in the 37 degrees C, 5% CO2 incubator after recovery. The experiment samples were divided into six groups (control group, 2, 4, 6, 8, 10 Gy). After growing to logarithm period, Tca8113 cells were irradiated using above-mentioned X-ray doses. The immunocyteochemistry and Western blot were used to detect the expression of NF-kappaB P65 after irradiation in various times (1, 3, 6, 10, 24, 48 h). The apoptosis rates under different radiotherapy dose were detected by flow cytometer and TDT-mediated dUTP-biotin nick end labeling (TUNEL).
RESULTSCompared with the control group, cytoplasm expression of P65 under different X-ray doses had statistically significant differences (P < 0.05). While the cytoplasm P65 protein expression at different time were compared each other, the 3 h group demonstrated significant difference (P < 0.05). Apoptosis rates in various groups, compared with control group, had statistically significant differences (P < 0.05). While the groups at different time points were compared each other, the apoptosis rates of 3 h group had significant differences (P < 0.05).
CONCLUSIONX-ray can activate the NF-kappaB P65 in oral squmaous cell carcinoma cell lines. The correlation between expressional quantity of P65 and radiotherapy induced apoptosis of oral squamous cell carcinoma cell lines possesses positive correlation. The activated and intranuclear P65 may have radiotherapy resistant effect.
