Objective To investigate the relationship between the apparent diffusion coefficient(ADC) value,portal hypertension and hypersplenism.Methods 52 cases underwent MR imaging (including DWI) examination,among them,included normal group(18 cases) hepatic cirrhosis without portal hypertension group(24 cases) and hepatic cirrhosis with portal hypertension group(10 cases).The ADC values of spleen were calculated and compared between groups.The relationship between target of hypersplenism——cells in peripheral blood(RBC/WBC/PLT) and spleen’s ADC values was also analyzed.Results With the appearance of portal hypertension,spleen’s ADC values decreased.The significant difference was found among these 3 groups(P

Objective:Investigate the relation between the phosphorylation of FOXO1 and the apoptosis and the proliferation of lymphoma cells and to clarify its specific mechanism.Methods:The lymphoma cells Namalwa and Jurkat were treated with PI3K inhibitor wort mannin or etoposide or Wortmannin plus etoposide for different times-pan and at different concentration.The inhibition rates for cell growth of lymphoma cells were examined by XTT assay.Apoptosis were detected by flow cytometry.The expressions of p-Akt,p-FOXO1,FOXO1 and Bim were determined by Western blot analysis.Results:Wortmannin induced apoptosis of Jurkat cells and Namalwa cells and inhibited their survival effectively.The growth inhibition rate and the apoptosis rate of lymphoma cells induced by Wortmannin plus etoposide were higher than those induced by etoposide alone.After treated with Wortmannin,phosphorylation of FOXO1 remarkably reduced and bim markedly increased.Conclusion:The dephosphorylation of FOXO1 inhibits proliferation of Jurkat cells and Namalwa cells,promotes their apoptosis and enhanced the sensitivity of Non-Hodgkin lymphoma cells to etoposide.Bim activated by FOXO1 promotes cell apoptosis.

Discipline evaluation is an effective and boosting mean of constructing high level key disciplines,but if there is something wrong or flaws with the means,indicators,process,ways,the effect may be just the opposite.Therefore,establishing scientific evaluation system is an important premise to construct key disciplines,promote discipline development and improve the level of academy construction.This article which is aimed at current situation of discipline evaluation system,puts forward some major principles to establish scientific evaluation for discipline,it is significant to play a right evaluation guide and promote the discipline construction.Carrying out discipline evaluation needs to have right guiding thought,establish and perfect indicator system of discipline evaluation,strengthen orderly management of evaluation work,offer scope to stimulate function of discipline evaluation.Only in these ways,can we construct a batch of characteristic and competitive key disciplines.

Objective To establish a HPLC-ELSD method for determining the content of astragaloside Ⅳ in Qingshen Jianfei Tablets. Methods Stationary phase was C_(18) column (4.6 mm?250 mm, 5 ?m), mobile phase was acetonitrice-water (35 : 65). The evaporation temperature was 120 ℃, the pulverization temperatire was 80 ℃, the flow rate was 1.6 mL/min and column temperature was 35 ℃. Results The standard curve was linear within the range of 1.03~8.24 ?g, r=0.9999. The average recovery was 99.35% with RSD = 1.36% (n = 6). Conclusion The established method is simple and accurate, with good reproducibility and high precision, and suitable for the determination of astragaloside Ⅳ in Qingshen Jianfei Tablets.
6. Efficacy and safety of bevacizumab combined with chemotherapy in treatment of EGFR wild type or EGFR-TKI resistant lung adenocarcinoma with brain metastases
Tumor 2016;36(10):1139-1145
Objective: There is no standard chemotherapy regimen for patients with wild type epidermal growth factor receptor (EGFR) and EGFRtyrosine kinase inhibitor (TKI) resistant lung adenocarcinoma with brain metastases. This study aims to observe the efficacy and toxicity of chemotherapy combined with bevacizumab in wild-type EGFR and EGFR-TKI resistant lung adenocarcinoma patients with brain metastases. Methods: A total of 10 lung adenocarcinoma patients with brain metastases between January and December 2015 received bevacizumab and chemotherapy. The response was evaluated by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) every 2 cycles and the toxicity was evaluated by National Cancer Institute-Common Toxicity Criteria version 3.0 (NCI-CTC 3.0) every cycle. Results: Of the eight patients who could be evaluated for response, the overall response rate was 25% (2/8) and the disease control rate was 75% (6/8). And for intracranial lesions, the response rate was 12% (1/8) and the disease control rate was 87% (7/8). The most commonly adverse events induced by bevacizumab were hypertension, proteinuria and bleeding, which were mostly degrees I-II. Conclusion: Bevacizumab combined with chemotherapy is an effective and safe treatment method for EGFR wild type and EGFR-TKI resistant lung adenocarcinoma patients with brain metastases.

HIV-1 integrase enzyme is a 32kDa protein encoded by HIV pol gene. It is responsible for integration of viral cDNA into host chromosomal DNA, which is indispensable for HIV replication.Since there was no functional equivalent for this enzyme in human cells, inhibition of integrase will bring little side effect to human body. Thus HIV integrase has become an attractive and rational target for therapy of AIDS after reverse transcriptase and protease.The Recent research on HIV-1integrase structure,inhibitors and new therapeutic method target at HIV integrase was reviewed.

Objective To study the changes of neutrophil surface molecule CD64 and inflammatory factor levels in patients with burn infection. Methods 46 cases of patients with burn infection who were treated in the department of burn in our hospital between March 2010 and October 2015 were selected as the observation group. Meanwhile, 46 cases of healthy people who underwent physical examination in our hospital during the same period were included in the control group. The levels of neutrophil surface molecule CD64, C-reactive protein (CRP), white blood cell count (WBC) and inflammatory factor [interleukin IL-6 (IL-6), interleukin (IL-8), tumor necro-sis factor (TNF-α) in the two groups of subjects were determined by flow cytometry and were compared. Results In the observation group, the levels of CD64, CRP, WBC and inflammatory factors were significantly higher than those in the control group (P < 0.05). Conclusion The levels of CD64, CRP, WBC and inflammatory factors in patients with burn infection are significantly higher than those in healthy people , which indicates that neutrophil surface molecule CD64, inflammatory factors and burn infection are closely correlated.

[ ABSTRACT] AIM: To explore the relationship between FRAS 1 protein and brain metastases of non-small cell lung cancer (NSCLC).METHODS:The mRNA expression of FRAS1 in the brain metastatic tumor tissues and primary tumor tissues of NSCLC was detected by qPCR .The protein expression of FRAS 1 in the tumor tissues and normal tissues adjacent to tumor tissues of NSCLC was measured by SP method of immunohistochemistry .The protein expression of FRAS 1 in NSCLC primary tumor tissues with or without brain metastases was also determined .RESULTS:The mRNA expression of FRAS1 in the brain metastatic zone was nearly 10 times higher than that in the primary tumor tissues , and there was sig-nificant difference between the 2 groups (P<0.05).FRAS1 protein was expressed in the NSCLC primary tumor tissues , but was not found in the normal tissues adjacent to primary tumor tissues .The protein expression of FRAS 1 in the NSCLC with brain metastases was significantly higher than that without brain metastases ( P<0.01 ) .CONCLUSION: FRAS1 protein may be associated with the occurrence of NSCLC .The over-expression of FRAS1 protein may be related to brain metastases with NSCLC .
