Pancreatic cancer with liver metastases (PCLM) is a refractory malignant tumor characterized by insidious onset, rap-id progress, and poor prognosis. Only a few patients had the opportunity of receiving surgical treatment. PCLM is primarily treated by systemic chemotherapy. The chemotherapeutic regimen of 5-fluorouracil, oxaliplatin, irinotecan, and leucovorin has become the first-line therapy for PCLM patients with good performance status. Gemcitabine-based chemotherapy is still very important in treating PCLM. Nab-paclitaxel plus gemcitabine, which has been found to increase survival, is recommended as a new standard for treating PCLM patients. However, still no breakthrough has been established in the study of gemcitabine plus molecular-targeted therapy. Sys-temic chemotherapy combined with trans-catheter arterial chemoembolization is valuable and may be effectual in prolonging survival. Further investigation of prospective and randomized controlled clinical trials is necessary. Radio frequency ablation and brachy-thera-peutic embolization with yttrium-90 microspheres are still in the exploratory stage. Multimodality treatment of PCLM using chemother-apy, radiation therapy, and Chinese herbal medicine is gaining wide acceptance. This article reviews the recent progress in the treatment of PCLM.

Objective To investigate the application value of liquid-based thinprep cytologic test ( TCT) in diagnosis of cervical cancer and precancerous lesion. Methods The results of liquid-based thinprep cytologic test and TBS cytology subdivision from 9 012 patients were retrospectively analyzed, including 12 cases of ASC-US, 10 cases of ASC-H, 35 cases of LSIL, 72 cases of HSIL, 2 cases of SCC, and 6 ca-ses of gland cell abnormal. The abnormal results and the results of biopsy pathological diagnosis underwent colposcopy were compared. Results The liquid-based thinprepcytologic test showed that there were 285 cases of atypical squamous cells of undetermined significance (ASC-US), the positive rate was 3. 2%. The accordance rate of liquid-based thinprep cytologic test and colposcope histopathological diagnosis was 91. 24%. Conclusion TCT and TBS system can accurately reflect cervical intraepithelial lesion. Early detection and treatment of precancer-ous lesions is the key point of preventing cervical cancer.

Objective To investigate the anti-microbial activity of genistein and its mechanism. Method The anti-microbial experiment was carried out by utilizing scanning and transmission electron microscope(SEM and TEM) ,and further analyzing the respiratory metabolism and change of SDS-PAGE protein spectra. Results Genistein could inhibit several kinds of bacteria obviously.The erose structures such as rugae and bubbles were observed on the surface of cells by SEM after 24h. Moreover,with TEM,we detected the shrinkage of cytoplasm,the plasmolyses,and then the breach of wall and membrane along with the outflow of protoplasm in Staphylococcus aureus treated with genistein for 4h,14h and 24h respectively. Notablely the respiratory inhibition experiment revealed that the genistein mainly inhibits the TCA cycle of bacteria. Besides,the SDS-PAGE elucidated that the total expression of proteins was decreased in the cell treated with genistein,and especially the larger proteins were reduced with 90.1%. Conclusion Genistein showed obvious anti-microbial activity to Staphylococcus aureus. It could destroy the integrity of cell wall and membrane,prevent the respiratory metabolism and protein synthesis of the bacteria.

Objective To study the changes of Toll like receptor 4,7 (TLR4,TLR7) protein in cervical squamous cell carcinoma ( CSCC) tissues and the relationship between expression and clinical pathological characteristics of the patients. Methods A total of 67 pa-tients with CSCC carcinoma( CSCC group) ,30 patients with cervical intraepithelial neoplasia( CIN group) and 30 patients with normal cervi-cal tissues(normal group) were detected by immunohistochemical method. The expression of TLR4,TLR7 protein and its clinical pathological characteristics of patients with CSCC in the samples were analyzed. Results TLR4,TLR7 protein positive rate of CSCC group were respec-tively 80. 60% and 76. 12%,which were significantly higher than those of CIN group (46. 67%,40. 00%) and the normal group(13. 33%, 10. 00%),the difference was statistically significant (P<0. 05). TLR4,TLR7 protein positive expression rate in CIN group was significantly higher than that in the normal group (P<0. 05). The positive expression of TLR4 protein and CSCC in patients with FIGO stage,pathological grade,depth of invasion had a significant relationship(P<0. 05),pathological grade,the positive expression of TLR7 protein and CSCC in pa-tients with invasive depth had a significant relationship(P<0. 05). Conclusion There is increased expression of TLR4,TLR7 protein in cervical tissues of CSCC patients,and a certain relationship between the factors and clinical staging,pathological grading.

Objective To investigate the role and mechanism of ABI family member 3-binding pro-tein(ABI3BP)in dysfunction of endothelial progenitor cells(EPC)induced by angiotensin Ⅱ(Ang Ⅱ).Methods EPC were divided into sh-RNA negative control(sh-NC)group(transfected with LV-scramble-shRNA+PBS),sh-ABI3BP group(transfected with LV-ABI3BP-shRNA+PBS),sh-NC+Ang Ⅱ group(transfected with LV-scramble-shRNA+Ang Ⅱ)and sh-ABI3BP+Ang Ⅱ group(transfected with LV-ABI3BP-shRNA+Ang Ⅱ)to investigate the effect of silencing ABI3BP on the dysfunction of EPC induced by Ang Ⅱ.Transwell assay,adhesion assay,Matrigel tube formation assay,and TUNEL staining were performed respectively to detect the migration,adhesion and tube formation abilities and cell apoptosis in above cell groups.The expression chan-ges in integrin-β1/FAK/P53 signaling pathway were detected by Western blotting.Results Com-pared to the sh-NC group,the sh-NC+AngⅡ group showed significant decreases in the numbers of migratory cells,adhesion cells,and tubule formation,along with increases in the apoptotic rate and the expression levels of Integrin β1,p-FAK,and P53(P<0.05).While,the sh-ABI3BP+AngⅡ group had obviously more migratory cells(88.67±8.33 vs 62.33±7.37 units,P<0.05),adhe-sion cells(104.33±6.03 vs 68.33±10.05 units,P<0.05),and tubule formation(36.33±3.21 vs 19.33±3.06 units,P<0.05),while decreased apoptotic rate and expression levels of integrin-β1,p-FAK and P53 protein when compared with the sh-NC+AngⅡ group(P<0.05).Conclusion Ang Ⅱ can up-regulate the expression of ABI3BP,and knockdown of ABI3BP can improve Ang Ⅱ-induced EPC dysfunction,which may be related to its inhibition on integrin-β1/FAK/P53 signa-ling pathway.

Objective:To compare ultrasound (US) guided versus computed tomography (CT) guided radiofrequency ablation (RFA) in treatment of early hepatocellular carcinoma (HCC).Methods:The data of 133 patients with early HCC treated by RFA in the Department of Hepatobiliary Surgery of Shandong Provincial Hospital from February 1, 2015, to January 31, 2017, was analyzed retrospectively. These patients were divided into two groups: the US-guided group and the CT-guided group. The clinical data was collected and the factors affecting prognosis were analyzed.Results:Compared with the CT-guided group, the operation time of the US-guided group was significantly shorter [(29.0±12.0)min vs. (55.0±19.0)min, P<0.05], but the number of ablation sessions per tumor was significantly less [(1.1±0.3) vs. (2.0±0.6), P<0.05]. There was no significant difference in the complete ablation rates, postoperative complication rates and postoperative length of hospital stay between the two groups ( P>0.05). The CT-guided group was superior to the US-guided group in the local tumor recurrence and progression-free survival rates ( P<0.05). On multivariate analysis, CT-guided RFA was an independent protective factor for local tumor recurrence ( HR=0.266, 95% CI: 0.073-0.967, P<0.05) and progression-free survival ( HR=0.415. 95% CI: 0.213-0.806, P<0.05), while AFP >20 ng/ml ( HR=4.821, 95% CI: 1.714-13.560, P<0.05) was an independent risk factor for progression-free survival. Conclusion:CT-guided percutaneous RFA was superior to US-guided RFA in local treatment of early HCC, probably related to more needle placements and longer ablation time under CT guidance.
