Objective To explore the influence and mechanism of cytokines and protein expression of alveolar epithelial type (ACE) Ⅱ cells in Bama minipigs' right-thorax with a single 15 Gy dose irradiation.Methods All minipigs received either right thoracic irradiation or sham-irradiation under anesthesia.At 4,8,12 and 24 week post-irradiation,5 minipigs respective and random from irradiarion groups and control group were sacrificed to remove the lungs.The protein expression of surfactant associated protein (SP)-A,transforming growth factor (TGF)-β1,Vimentin and E-cadherin were detected by Western blot.The protein expression of α-smooth muscle actin (SMA) was detected by immunohistochemistry.The co-localization of SP-A and α-SMA was visualized by double immunofluorescence staining.Results At 4,8,12 and 24 week post-irradiation,a significant increase in the protein expression of α-SMA,TGF-β1 and Vimentin were observed in irradiated lung compared to sham-irradiated controls(α-SMA:t =2.46-3.26,P <0.05;TGF-β1:t =2.96-3.52,P <0.05;Vimentin:t =3.24-5.05,P < 0.05).By contrast,the protein expression of SP-A and E-cadherin in irradiation group was lower than it in control group (SP-A:t =3.62-4.65,P < 0.05;E-cadherin:t =2.53-4.15,P < 0.05).Moreover,at 8 week after irradiation,under confocal laser scanning microscope,the co-localization of SP-A and α-SMA was observed in irradiated alveolar epithelium cells,and it was not observed in sham-irradiated controls.Conclusions These data demonstrate that E-cadherin,SP-A and TGF-β1 may act as sensitive predictors of radiation-induced lung injury(RILI).Irradiation may lead to ACE Ⅱ cells achieving a mesenchymal phenotype,namely,epithelial to mesenchymal cells transition occurs,and ACE Ⅱ cells play the important part in the development of RILI by epithelial-mesenchymal transition.

Background and purpose:Bladder cancer is the most common urological tumor, and its pathogen-esis is still not fully understood. The study was aimed to observe the expressions of key genes in many tumor-associated signaling pathways in normal bladder tissue and bladder carcinoma, and to provide further evidence for the subsequent study of bladder cancer recurrence and metastasis.Methods:Twenty-seven cases of bladder cancer specimens were col-lected, and normal bladder tissues and bladder cancer tissues were distinguished by frozen section. Then, the expressions of 84 genes of cancer-related signaling pathways in bladder cancer tissues and normal bladder tissues were screened by Cancer Pathway Finder PCR Array produced by QIAGEN company.Results:Compared with the normal bladder tissues, the bladder carcinoma tissues had 8 up-regulated genes and 19 down-regulated genes. In this study, the impact of epithe-lial-mesenchymal transition (EMT) signaling pathway was selected as a research direction in which theGSC,KRT14,DSP were up-regulated,SNAI2,SNAI3 were down-regulated. ThereforeGSC,KRT14,DSP,SNAI2 andSNAI3 were chosen as target genes, and verified by qRT-PCR in many examples. The result showed that the expressions ofGSC gene in bladder cancer tissues were up-regulated, but with no statistical significance;KRT14,DSP expressions in bladder cancer were higher than those in normal bladder tissues (P<0.05);SNAI2,SNAI3 expressions in bladder cancer were lower than those in normal bladder tissues (P<0.05), andSNAI3 showed the most obvious expression differences.Conclusion:KRT14,DSP andSNAI3 may play an important role in bladder cancer’s occurrence, development and metastasis.

Objective To evaluate the efficacy and toxicity of induction chemotherapy with nedaplatin and docetaxel plus concurrent intensity?modulated radiotherapy ( IMRT) with nedaplatin or cisplatin in the treatment of locally advanced nasopharyngeal carcinoma (NPC). Methods A total of 223 patients with pathologically diagnosed locally advanced NPC in five treatment centers from 2011 to 2012 were randomly divided into two groups. In the test group, one hundred and thirteen patients received two cycles of induction chemotherapy with docetaxel (65 mg/ m2 on day 1) and nedaplatin (80 mg/ m2 on day 1) plus concurrent IMRT with nedaplatin (40 mg/ m2 on day 1). In the control group, 110 patients received two cycles of induction chemotherapy with the same regimens plus concurrent IMRT with cisplatin (40 mg/ m2 on day 1). The survival rates were calculated with the Kaplan?Meier method and the differences in the survival rates between the two groups were analyzed using the log?rank test. Comparison of the incidence rates of adverse reactions between the two groups was made by the chi?square test. Results The follow?up rate was 99?? 1%.The response rates at 3 months after treatment in the two groups were both 100%. The 2?year local recurrence?free, regional recurrence?free, distant metastasis?free, and overall survival rates were 94?? 0%, 94?? 2%, 88?? 2%, and 90?? 3%, respectively, in the test group, versus 93?? 4%, 94?? 1%, 86?? 7%, and 87?? 3% in the control group ( P= 0?? 757、 0?? 478、 0?? 509、 0?? 413). The incidence rates and severity of leucopenia, neutropenia, and thrombocytopenia were significantly higher in the test group than in the control group ( P= 0?? 027 , 0?? 028 , 0?? 035 ) . The incidence rates and severity of hemoglobin reduction and nausea /vomiting were significantly lower in the test group than in the control group (P= 0?? 000,0?? 023). There were no significant differences in the incidence rates of mucositis and xerostomia between the two groups ( P=0?? 483,0?? 781). Conclusions The short?term efficacy of induction chemotherapy with nedaplatin and docetaxel plus concurrent IMRT with nedaplatin is similar to that with cisplatin in the treatment of locally advanced NPC. The mild gastrointestinal reactions can be tolerated by patients. However, the severe myelosuppression should be closely monitored during the treatment.

OBJECTIVE:
To observe the change of serum homocysteine (Hcy) and anti-citrullinated peptide (CCP) antibody concentration in depression rat model induced by chronic unpredictable mild stress (CUMS), and to explore the immunologic mechanism of depression and the relation between depression and its autoimmunity.
METHODS:
Sixty adult male SD rats were randomly divided into 2 groups, 30 rats in each group, which were divided into 3 subgroups: a normal control group, a model group and a fluoxetinetreated group. The depression rat model was established under CUMS and seperated feeding, after which, open field, sugar consumption and forced swimming test were applied in the first group. After the blood was taken in the second group of rats through heart puncture, the level of serum Hcy was detected by enzymatic cycling assay and serum anti-CCP antibody by ELISA.
RESULTS:
Compared with the control group and the fluoxetine treatment group, spontaneous activity and sucrose consumption and preference percentage of the rats in the model group significantly reduced, while the immobility time in forced swimming test and the level of Hcy and anti-CCP antibody in the rat serum significantly increased.
CONCLUSION
Immunity inflammation and autoimmune reaction exist in CUMS depression model rats, and fluoxetine treatment can improve these immune response.

In this study, we used next-generation sequencing methods to screen 300 individuals for BRCA1 and BRCA2. A novel mutation (c.849dupT) in BRCA2 was identified in a female patient and her unaffected brothers. This mutation leads to the truncation of BRCA2 functional domains. Moreover, BRCA2 mRNA expression levels in mutation carriers are significantly reduced compared to noncarriers. Immunofluorescence and western blot assays showed that this mutation resulted in reduced BRCA2 protein expression. Thus, we identified a novel mutation that damaged the function and expression of BRCA2 in a family with breast cancer history. The pedigree analysis suggested that this mutation is strongly associated with familial breast cancer. Genetic counsellors suggest that mutation carriers in this family undergo routine screening for breast cancer, as well as other malignancies, such as prostate and ovarian cancer. The effects of this BRCA2 mutation on drug resistance should be taken into consideration during treatment.
