Background: We investigated whether the plant-derived agent triptolide (TPL) could effectively inhibit the growth and invasion of human hepatocellular carcinoma (HCC) cells. Material/Methods: MHCC-97H cells were treated with various concentration of TPL for various times. To detect the effect of NF-κB on TPL-induced signal pathways, MHCC-97H cells were transfected with p65 siRNA or p65 cDNA, then treated with TPL. We detected cell survival and apoptosis by MTT, soft-agar colony formation assay, flow cytometry, and TUNEL assay. Cell migration and invasion was determined by Matrigel invasion and a wound-healing assay. NF-kB activity was detected by electrophoretic mobility shift assay (EMSA); MMP-9 activity was detected by ELISA. Western blot and real-time PCR (RT-PCR) assays were used to detect p65 and MMP-9 protein and mRNA expression. A subcutaneously implanted tumor model of MHCC-97H cells in nude mice was used to assess the effects of TPL on tumorigenesis in vivo. Results: We showed that TPL treatment significantly suppressed growth and induced apoptosis of MHCC-97H cells in a dose- and time-dependent manner in vitro. Furthermore, TPL treatment inhibited invasion in vitro and inhibited the growth and lung metastasis of MHCC-97H cells in vivo. NF-κB and MMP-9 were inactivated with TPL treatment. Overexpression of p65 restored MMP-9 activity and inhibited the TPL anti-tumor effect on MHCC- 97H cells. Knockdown of p65 blocked MMP-9 activation and enhanced TPL-induced cell apoptosis and survival inhibition, and TPL inhibition of migration and invasion in vitro. Conclusions: TPL treatment inhibited MHCC-97H cell growth, invasion, and metastasis in vitro and vivo, suggesting that TPL could be developed as a potential therapeutic agent for the treatment of HCC. © Med Sci Monit, 2016.

The aim of this study was to investigate the clinical significance of the expression of DNA mismatch repair (MMR) genes in patients subjected to radical surgical removal of colon cancer, as well as their correlation with disease prognosis. Ninety stage II and III colon cancer patients who received laparoscopic radical resection of colon cancer at our hospital were recruited in this study. The expression of hMLH1, hMSH2, hMSH6, and hPMS2 in the resected tumor tissues was examined by SP immunohistochemistry, in order to analyze the relationship between defective DNA MMR (dMMR) and the clinico-pathological features and prognosis of colon cancer. Patients were followed up over a period of 5-35 months, and the Kaplan-Meier survival curve was plotted. dMMR was confirmed in 27 subjects (30.0%), among whom recurrence with metastasis and death was reported in 5 (18.5%) and 2 (7.4%) patients, respectively. The remaining 63 subjects displayed proficient DNA MMR (pMMR); among these, 19 (30.2%) and 7 (11.1%) recurrences with metastasis and death were reported, respectively. dMMR showed no significant correlation with gender, age, or therapeutic modality (P > 0.05), but was significantly correlated with the degree of differentiation, tumor location, number of resected lymph nodes, presence of ileus, and TNM stage (P < 0.05). The prognosis of patients with dMMR was better than that of patients with pMMR. dMMR serves as a biomarker for the prognosis of stage II/III colon cancers. © 2016 The Authors.

Objectives: This study focused on the expression pattern and clinical significance of B7-H3 expression in human acute leukemia. Methods: We systematically analyzed 134 patients with acute myeloid leukemia (101 cases) and acute lymphocytic leukemia (33 cases) by flow cytometry. Results: The frequency of B7-H3+ cases was 44.8% in total. The B7-H3 expression rate differed from 0% to 74.8% in individual cases. The correlation between B7-H3 expression and traditional prognostic factors, such as age and gender, the white blood cell count was not confirmed. However, B7-H3 had a significant higher expression in CD34+ cases and high risk karyotypes. Conclusions: Owing to the expression of B7-H3 being statistically relevant in predicting disease progression and a shorter life survival, our results demonstrated that B7-H3 expression in acute leukemia predicts an unfavorable outcome. © W.

To investigate the effectiveness of the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique for congenital buried penis. Between March 2010 and June 2012, 68 boys with congenital buried penis were treated by the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique, with a median age of 4 years and 10 months (range, 3 months-13 years). Of 68 cases, 14 were classified as phimosis type, 14 as rope belt type, 20 as moderate type, and 20 as severe type. The body of penis developed well and had no deformity. After operation, complications were observed, and the effectiveness was evaluated by the designed questionnaire. Early postoperative complications occurred in 11 cases, including obvious adhesion of the outside wrapping mouth in 4 cases, scrotal skin bloat in 5 cases, and distal foreskin necrosis in 2 cases; long-term complications occurred in 9 cases, including abdominal incision scar formation in 4 cases, wrapping mouth scar stricture in 3 cases, and short penis in 2 cases. Primary healing of incision was obtained in the other boys. Fifty-four cases were followed up 6-12 months (mean, 8 months). According to the designed questionnaire, satisfaction rate with the overall view in parents was 77.78% (42/54); the clinical improvement rate was 85.19% (46/54); exposure of the penis was satisfactory in parents of 50 cases; and the parents had no psychological burden of penis exposure in 46 cases, which were significantly improved when compared with preoperative ones (P < 0.05). The boys had no psychological burden of penis exposure in 29 cases (53.70%) after operation, showing no significant difference when compared with preoperative one (18 cases, 33.33%) (chi2 = 1.22, P = 0.31). Application of the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique can effectively correct congenital buried penis.

Fibroblast growth factor receptor 2 (FGFR2) has been proved to be a significant prognostic factor and a potential therapeutic target in several types of cancer, including gastric cancer. FGFR2 consists two isoforms: FGFR2-IIIb and FGFR2-IIIc, which can be stimulated by different ligands and trigger different downstream signaling pathways. As a specific ligand to FGFR2-IIIb, fibroblast growth factor 10 (FGF10) is expressed in the gastric mesenchyme cell and is involved in stomach development and morphogenesis, but its expression and clinical significance is not well elucidated in gastric cancer. We analyzed FGF10 expression by immunohistochemistry in 178 samples of gastric adenocarcinoma (134 male and 44 female patients, with the average age of 63.2 years old and the average follow-up of 21.6 months). Using the arbitrarily scoring method based on positive cell percentage and staining intensity, we sub-divided the patients into FGF10 high-expression group (58 patients) and low-expression group (120 patients). We thus found that FGF10 expression is significantly associated with lymph node invasion (P = 0.004) and distant metastasis (P = 0.032). Importantly, FGF10 expression is an independent unfavorable prognostic factor (P = 0.042). Moreover, FGF10 knockdown significantly decreased the migration of cultured gastric adenocarcinoma cells, suggesting that FGF10 could promote the invasion of gastric adenocarcinoma. In conclusion, FGF10 expression was identified as a poor prognostic biomarker in gastric adenocarcinoma, and FGF10 could promote the invasion of gastric cancer cells. We suggest that FGF10 could be a potential and promising drug target in gastric adenocarcinoma. © 2015 Tohoku University Medical Press.

Objective: To observe the effect of aqueous extract from roots of Arctium lappa (AERAL) on vascular remolding in hypertensive rats. Methods: The hypertensive rat model was induced by N-nitro-L-arginine from 50 female Wistar rats, and randomly divided into model control group, positive control group (15 mg/kg), low-, mid-, and high-dose AERAL (0.5, 1.0, and 2.0 g/kg), groups. After six weeks of continuous gavage administration, rat tail artery systolic pressure, angiotensin II (Ang-II), endothelin-1 (ET-1), tumor necrosis factor-α (TNF-α), left ventricular mass index (LVWI), and thickness of thoracic aortic tunica media (TTATM) were detected. Results: Compared with the normal control group, Ang-II, ET-1, TNF-α, LVWI, and TTATM were increased and rat tail artery systolic pressure was elevated in the model control group, with significant differences between the two groups (P < 0.05); Compared with the model control group, rat tail artery systolic pressure in each treatment groups declined, serum Ang-II, ET-1, TNF-α, LVWI, and TTATM were all lowered, showing significant differences among them (P < 0.05). Conclusion: AERAL can significantly improve vascular remolding in rats with hypertension. © 2015, Editorial Office of Chinese Traditional and Herbal Drugs. All right reserved.

OBJECTIVE: To investigate the application of circulating tumor cells (CTC) detection in chemotherapeutic efficacy evaluation in metastatic breast cancer(MBC). METHODS: 136 patients were enrolled in this study. The tumors were monitored by computed tomography every 3 chemotherapy cycles and evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST). In the mean time, the levels of CTCs were monitored using cell filtration (isolation by size of epithelial tumor cells, ISET) together with laser scanning cytometry (LSC). RESULTS: Among the 341 samples collected from 136 patients, CTC could be found in 262 specimens (76.83%), and the mean number of CTC was (6.73±4.92)/7.5 mL blood. Among the 136 patients, 43 cases achieved complete or partial remission (31.62%). 39 cases remained stable (28.67%). And 54 cases were progressive (39.71%). Changes in CTC numbers were significantly associated with the disease progresses after chemotherapy (r=0.514 83, P<0.01). However, CTC baseline level did not predict response to treatment (χ2=3.62, P=0.08215). CONCLUSION: CTC detection could be used in the efficacy evaluation of chemotherapy in MBC. © 2015, Editorial Board of Chinese Journal of Cancer Prevention and Treatment. All right reserved.
