Objective To investigate the effects of ozone (O3) on Wnt/β-catenin signaling pathway in the articular cartilage of rats with osteoarthritis (OA).Methods Eighteen male SPF Wistar rats,aged 3 months,weighing 200-250 g,were randomly divided into 3 groups (n =6 each) using a random number table:control group (group C),group OA,and O3 group (group O).OA was induced by injection of monosodium iodoacetate 3 mg (50 μl) into the right knee joint cavity.On 7th day after the model was established successfully,25 μg/ml O3 1 ml were injected into the knee joint cavity,once a week for 3 consecutive weeks in group O.Behavioral changes were observed after establishment of the model.At 1 day before establishment of the model,and 1,4,7,14,21 and 28 days after establishment of the model,the mechanical paw withdrawal threshold (MWT) was measured.At 28 days after establishment of the model,the total knee joint was removed and stained with haematoxylin and eosin for examination of the pathological changes of the cartilage (under light microscope) and for determination of the expression of β-catenin and matrix metalloproteinase-13 (MMP-13) in the cartilage (by immunohistochemistry).Results The signs of OA such as hind-limb motor dysfunction,knee joint swelling,or decreased joint motion,and signs of hyperalgesia such as lickings were observed after establishment of the model in rats.Compared with group C,the MWT was significantly decreased at each time point after establishment of the model,and the ex pression of β-catenin and MMP-13 in the cartilage was significantly up-regulated in the other two groups(P＜0.05).Compared with group OA,the MWT was significantly increased at 7-28 days after establishment of the model,and the expression of β-catenin and MMP-13 in the cartilage was significantly down-regulated in group O (P＜0.05).The pathological changes of the cartilage were significantly reduced in group O as compared with group OA.Conclusion The mechanism by which O3 mitigates OA is probably related to inhibition of Wnt/β-catenin signaling pathway activation in the articular cartilage in rats.

Objective To analyze CT and MR features of malignant peripheral nerve sheath tumor (MPNST)of children. Methods Sixteen patients with histologically proven MPNST were retrospectively reviewed.There were 8 male and 8 female, ages from 0.3 to 11.0 years, and median age was 2.5 years. Sixteen cases were performed with CT plain scan, and eight cases with CT enhancement scans, and three with MR examination. The imaging data were analyzed by two highly experienced doctors and obtained agreements after mutual consultation. Results Among 16 cases, 3 cases were located at neck, 5 cases at waist and back,3 cases at abdominal and pelvic, 2 cases at foot, 1 case at left clavicle, 1 case at right mediastinum, 1 case at right orbit. Fifteen cases appeared as solid masses and 1 case showed a diffuse growth. CT plain scan showed 8 cases were solid-appearing masses and 7 cases were cystic-solid mass. Enhanced CT showed enhancement of solid component was moderate to marked and gradually delayed enhanced while cystic component had no any enhancement. One was located on the left side of the neck and appeared as diffuse growth. Two cases of solid mass type appeared as hypo-intensity on T1WI and hyper-intensity on T2WI, and obviously high signal intensity of cystic component on T2WI, and with significantly heterogeneous enhanced.One case with diffuse growth appeared as hypo-intensity on T1WI and slightly hyper-intensity on T2WI, and with significantly enhanced. Sixteen cases appeared as invasive growth, 11 caseswith multiple organic metastases and recurrences, and 4 cases with neurofibromatosis type I and scoliosis.Conclusion CT and MR appearances of MPNST have certain characteristic features, and can demonstrateaggressive performance and multiple organic metastases, which is helpful for definite diagnosis and treatment plan.

Objective To investigate the molecular mechanism of epithelial-mesenchymal transition (EMT) induced by activated vascular endothelial growth factor receptor-1 ( VEGFR-I ) in cell line MHCC97-H.Methods MHCC97-H cells were cultured in DMEM with 1％ fetal bovine serum (control group),10 μmol/L PP2 (PP2 group),10 μmol/L PBS (PBS group),50 μmol/L VEGF-B (VEGF-B group),l0μmol/L PP2 and 50 μmol/L VEGF-B (PP2 +VEGF group),10 μmol/L PBS and 50 μmol/L VEGF-B (PBS + VEGF-B group),respectively.Protein expressions of epithelial marker E-cadherin,α-catenin and mesenchymal marker vimentin and N-cadherin were detected by Western blot.The expression sites of E-cadherin,α-catenin and mesenchymal marker vimentin and N-cadherin were detected by cell immunofluorescence.The ability of invasion and migration of cell line MHCC97-H were assessed by cell invasion and migration test.All data were analyzed by the t test.Results The expressions of E-cadherin,α-catenin,vimentin and N-cadherin were 3.23 +0.76,3.01 ±0.25,3.01 +0.22 and 2.63 +0.40 in the control group,4.18 +0.32,3.29 +0.11,4.85 +0.36 and 3.02 +0.52 in the PP2 group,2.83 +0.65,3.03 +0.27,1.37 ±0.24 and 2.98 ±0.36 in the PBS group,2.06 ±0.15,2.84 ±0.76,5.79 ± 0.38 and 5.54 ± 0.28 in the VEGF-B group,6.12 ± 0.08,5.45 ± 0.37,3.36 ± 0.42 and 3.26 ±0.13 in the PP2 + VEGF-B group and 1.36 ±0.54,1.26 ±0.45,4.05 ±0.17 and 1.05 ±0.33 in the PBS +VEGF-B group.There was a significant difference in the expressions of E-cadherin and α-catenin between the PP2 +VEGF-B group and the VEGF-B group (t =7.625,9.931,P ＜ 0.05 ).The expressions of vimentin and N-cadherin in the PP2 + VEGF-B group were significantly lower than those in the VEGF-B group (t =12.001,11.910,P ＜ 0.05).Six hours after the treatment with VEGF-B,the numbers of MHCC97-H migrated were 19 ± 1,5 ± 2and 16 ± 1 in the VEGF-B group,PP2 + VEGF-B group and PBS + VEGF-B group,respectively.The number of MHCC97-H cells migrated in the VEGF-B group was greater than that in the PP2 ± VEGF-B group ( t =13.566,P ＜ 0.05 ).The number of MHCC97-H cells passed through the Boyden chamber was 4 + 2,which was significantly less than 16 ± 1 of the VEGF-B group (t =12.350,P ＜0.05).Conclusion EMT induced by activated VEGFR-1 was mediated via c-Src kinase signal transduction in MHCC91-H cell line,and c-Src may be a potential target to interfere the invasion and migration of hepatic cancer cells.

ObjectiveTo investigate the radiosensitizing effect of 3-(5'-hydroxy-2'-furyl)-1-benzyl indazole ( YC-1 ) on hypoxic human adenocarcinoma cell line A549.MethodsMTT assay was used to test the inhibitory effect of YC-1 on proliferation of A549 cells.Clonogenic assay was performed to determine the radiosensitizing effect of YC-1 on hopxic A549 cells.Single-hit multi-target model was used to plot survival curve and calculate sensitization enhancement ratio (SER).The cell cycle and apoptosis were measured by flow cytometry.ResultsThe proliferation of A549 cells was inhibited by YC-1 in a time-dose-dependent manner.In normoxic and hypoxic cells,the IC20 was 16.7 μmol/L and 39.2 μmol/L at 24 h,respectively.In the group of hypoxia plus YC-1,SERD0 and SERDq were 1.11 and 1.26,respectively.In hypoxia,YC-1combined with 2 Gy irradiation could induce cell apoptosis and prolong G2 + M phase arrest ( ( 30.17 ±1.21 )％ ∶ ( 15.44 ±0.96) ％,P =0.000; (21.56 ±0.47 )％ ∶ (6.16 ±0.16)％,P =0.000).Concinsions YC-1 could enhance the radiosensitivity of hypoxic A549 cells.

Objective To investigate the therapeutic effects of recombinant human endostatin (RHES) combined with radiotherapy on brain metastases (BM) of non-small cell lung cancer (NSCLC) and the patients suitable for this therapy.Methods Eighty patients with BM of NSCLC were randomly divided into RHES combined with radiotherapy group (combination group) and radiotherapy alone group (each group with 40 patients).The short-term effective rate,overall survival time,cerebral edema index and adverse reactions were observed and the expressions of vascular endothelial growth factor receptor 2 (VEGFR2) protein in primary lesions were detected with immunohistochemical method in all patients.Results Compared with radiotherapy alone group,brain edema was significantly relieved (t=4.9,P=0.000) and there were no marked adverse reactions in combination group.In short-term effective rate,there was no statistical significance in total population (n=80,90％ vs.75％,x2=3.11,P=0.07),but there was statistical significance in the patients with positive VEGFR2 (93％ vs.67.7％,x2=6.31,P=0.012).In overall survival time,there was no statistical significance in total population (n=80,P=0.35,95％ CI:0.25-1.30) or in the patients with positive VEGFR2 (P=0.109,95％ CI:0.40-1.34).Conclusion Compared with radiotherapy alone,RHES combined with radiotherapy can relieve brain edema in the patients with BM of NSCLC and obtain better short-term effective rate in the patients with positive VEGFR2.
