Objective To summarize the first experience with ultrasound-guided percutaneous ab lation treatment (PAT) for recurrent hepatoblastoma (HB) after liver resection in children.Methods From August 2013 to April 2015,PAT was used to treat 6 children with a total of 9 recurrent HB,including 5 patients with 8 tumors in the liver and 1 patient with 1 tumor in the lung.The mean size of ablated tumors was (1.5 ± 0.8) cm,and the tumor size range was 0.7 cm to 3.1 cm.Results Four patients were performed percutaneous radiofrequency ablation (RFA) for recurrent HB;and 2 patients were performed percutaneous ethanol injection (PEI).Ablation success was achieved in all patients (6/6,100%).The complete ablation rate after the first ablation session was 88.9% (8/9) on a tumor-by-tumor basis.Only 1 patient developed a fever with temperature > 39 ℃;it was resolved by conservative therapy.During the follow-up period of 5-30 months,3 patients died to tumor progression.The 1-and 2-year overall survival rates after ablation were 83.3% and 41.7%,respectively.Conclusions PAT is a safe and promising therapy for children with recurrent HB after liver resection,and further investigation in large-scale randomized clinical trials is required to determine its role in the treatment of this disease.

ObjectiveTo investigate the expression of survivin,COX-2 and bcl-2 in non-Hodgkin lymphoma(NHL)and the significance and correlation between them.MethodsImmunohistochemistry MaxVision systems for survivin,COX-2 and bcl-2 were conducted on 44 NHL and 20 reactive lymphoid hyperplasia (RH).ResultsThe positive expression rates of survivin,COX-2,bcl-2 in NHL were 70.45 %(31/44),68.18 % (30/44),63.64 % (28/44),respectively,and these in RH were 40.00 % (8/20),40.00 %(8/20) and 20.00 % (4/20),respectively.There was positive correlation between the expression of COX-2 and survivin (r =0.306,P =0.043),survivin and bcl-2 protein (r =0.339,P =0.040) in NHL.ConclusionCOX-2,survivin,bcl-2 are highly expressed in NHL.To detect the expression of them has clinical value to diagnosis NHL and to estimate the malignant degree of lymphoma.There are a positive correlations between the expression of COX-2 and survivin protein,and between the expression of survivin and bcl-2 protein,which indicates that they may play a synergistic role in the occurrence and development of NHL.

Objective To objectively and systematically evaluate the prognostic significance of nestin in glioma patients with Meta-analysis.Methods A systematic literature search of PubMed/Medline,Web of Science,Cochrane Library and Google scholar was performed to recruit studies between January 1990 and May 2015 that evaluated the correlation of nestin with overall survival (OS) and progression-free survival (PFS) in glioma patients.A Meta-analysis (R-3.1.3) was conducted to analyze the prognostic significance of nestin in glioma patients.Results A total of 8 studies with the total number of 1313 patients met inclusion criteria.The analysis demonstrated negative associations between nestin high expression and both poor OS (hazard ratio [HR]=1.64,95% confidence interval [CI] =1.27-2.12,P=0.0001) and PFS (HR=1.54,95%CI=1.04-2.28,P=0.0301).WHO grading was the main source of heterogeneity of OS data (P=0.0015),and the lower the WHO grade,the more significant the influence in OS.The sample capacity was the main source of heterogeneity of PSF data (P=0.008),and the larger the sample capacity,the more significant the influence in PFS.Conclusion The nestin expression can be used for accurately assessing the survival of glioma patients,thus,nestin could be recommended as a useful survival biomarker in clinical practice.

Bullous pemphigoid is a chronic obstinate dermatological disease. Hormone is the main therapeutic method, but the disease course is rather long, relapse is frequently seen and difficult to be radically cured; many complications may occur such as pulmonary infection, etc. From traditional Chinese medicine (TCM) basic principal points of view "lung governing skin and hair" and "strengthen the body resistance to eliminate pathogenic factors", the author explored the TCM therapy of bullous pemphigoid. By using clearing away lung heat and invigorating lung qi as the main principles supplemented by invigorating spleen and kidney, eliminating phlegm and blood stasis for treatment of such disease, relatively satisfactory therapeutic results were obtained.

Objective:To explore the effects of BCR-ABL downstream pathway inhibitors, such as RAF inhibitor SB590885, JAK inhibitor AZD1480, PI3K-mTOR double target inhibitor BEZ235 on chronic myelogenous leukemia (CML) cells, and the effect of BEZ235 on the proliferation, apoptosis of CML cells and the sensitivity of imatinib in vitro.Methods:K562 cells were treated with different concentrations of the drugs. MTS method was applied to detect the proliferation inhibition rate of K562 cells, and 50% inhibitory concentration (IC 50) of all drugs for 48 h was calculated. The cell apoptosis rate was tested by using flow cytometry with Annexin V-FITC/PI double staining. The cell cycle was tested by using flow cytometry with PI staining. K562 cells, imatinib-resistant and T315I-mutant human CML KBM7R cells and imatinib-resistant CML primary cells of patients were treated with different concentrations of the drugs. MTS method was used to test the proliferation inhibition of cells, and IC 50 of all drugs for 48 h was evaluated. KBM7R cells or primary cells of CML patients were treated with 1.0 μmol/L BEZ235, 1.0 μmol/L imatinib or the combination of both, respectively. Flow cytometry with PI staining was used to detect the cell cycle of KBM7R cells. Flow cytometry with Annexin V-FITC/PI double staining was used to detect the cell apoptosis rate in CML primary cells. The expressions of p-AKT, cleaved Caspase-3 and Cyclin D1 proteins were detected by using Western blot. Results:SB590885, AZD1480 and BEZ235 could inhibit the proliferation of K562 cells, and the IC 50 after the treatment of K562 cells for 48 h was (11.49±3.14), (4.83±1.26) and (0.37±0.21) μmol/L, respectively. SB590885, AZD1480 and BEZ235 could promote the apoptosis of K562 cells. The cell apoptosis rates were increased compared with the control group without drug treatment (all P < 0.01). SB590885 and BEZ235 induced G 0/G 1 block (both P < 0.05). AZD1480 induced G 2/M block ( P < 0.05). BEZ235 could inhibit the proliferation of K562 cells, KBM7R cells and CML primary cells, and their IC 50 for 48 h was (0.37±0.21), (0.43±0.27) and (0.49±0.24) μmol/L, respectively. Compared with imatinib alone, the different concentrations of imatinib combined with 0.2 μmol/L BEZ235 could increase the proliferation inhibition of K562 cells, KBM7R cells and CML primary cells, and could reduce the IC 50 of imatinib. After the treatment of imatinib alone and combination with BEZ235 for 48 h, the imatinib IC 50 of K562 cells was (0.14±0.05) and (0.09± 0.04) μmol/L ( t = 1.531, P = 0.249), the imatinib IC 50 of KBM7R cells was (3.93±2.29) and (0.44±0.22) μmol/L ( t = 2.837, P = 0.047), the imatinib IC 50 of the primary cells was (3.12±1.53) and (0.39±0.23) μmol/L ( t = 3.925, P = 0.042). The cell apoptotic rate of the primary cells was (4.9±1.4)%, (13.1±3.2)%, (8.8±2.0)% and (40.6±6.0)%, respectively in the control group without drug treatment, 1.0 μmol/L BEZ235, 1.0 μmol/L imatinib and the combination of 1.0 μmol/L BEZ235 and 1.0 μmol/L imatinib after the treatment of 24 h ( F = 71.031, P < 0.01). Compared with imatinib alone, the expressions of p-AKT and Cyclin D1 proteins were decreased, and the expression of cleaved Caspase-3 protein was increased after the treatment of KBM7R cells for 12 h in the combination group of both BEZ235 and imatinib. Conclusions:BCR-ABL downstream pathway inhibitors can effectively inhibit the proliferation and promote the apoptosis of K562 cells. BEZ235 can inhibit the proliferation and promote the apoptosis of K562 cells, imatinib-resistant and T315I-mutant human KBM7R cells and imatinib-resistant CML primary cells of patients, which has a synergistic effect to imatinib.

A farm worker in Baodi District of Tianjin was diagnosed with Tsutsugamushi disease due to fever and intermittent cough for more than 3 months.The patient's diagnosis and treatment process was complicated, and the diagnosis was delayed in the early stage of the disease because the clinician neglected the occupational history and lacked knowledge about the prevention and control of tsutsugamushi disease. As an important part of the epidemiological history, occupational history is crucial for the diagnosis of occupational related diseases. Clinical thinking runs through the whole process of clinical diagnosis and disease treatment, and correct clinical thinking can effectively reduce the occurrence of misdiagnosis.Clinicians should ask and record career history in detail to improve the quality of health care.
