Objective To explore the methylation status of Rap1 GTPase activating protein (Rap1GAP) promoter in colon cancer, and to provide the oretical basis and research direction for the early diagnosis, targeted therapy, anti-multidrug resistance of colon cancer and so on. Methods The paraffin embedded specimens of 33 patients with colonic adenocarcinoma diagnosed by pathology were analyzed from Department of Pathology of Xinzhou City People′s Hospital from January 2010 to September 2014, including 19 males and 14 females, and aged 41-72 years old. The paraffin embedded specimens of 16 patients with colonic adenoma were enrolled, including 9 males and 7 females, and aged 34-58 years old. 13 normal tissues from the tumor distal margin (from the tumor > 15 cm) were selected. Quantitative methylation specific PCR (q-MSP) was applied to detect methylation level of Rap1GAP gene promoter. The methylation level differences of Rap1GAP gene promoter region among 3 groups or between different clinicopathologic factor subgroups were compared. Results The methylation rates [median (interquartile range)] of Rap1GAP promoter were 65.43 % (50.35 %), 21.37 % (8.39 %) and 17.43 % (15.71 %) in colonic adenocarcinoma group, colonic adenoma group and adjacent normal tissue group, respectively. The methylation rate of colonic adenocarcinoma group was significantly higher than that of colon adenoma group or that of adjacent normal tissue group (P< 0.05). The methylation rates of Rap1GAP promoter in colonic adenocarcinoma were not correlation with age, sex, differentiation and the stage of TNM [ male vs. female: 42.74 % (70.44 %) vs. 21.98%(80.00%);≤60yearsoldvs.>60yearsold:36.26%(62.62%)and26.23%(76.42 %);well-differentiated vs. moderately/poorly-differentiated: 21.98 % (40.32 %) vs. 42.74 % (74.20 %); TNM Ⅰ-Ⅱ vsⅢ-Ⅳ: 25.31 % (48.27 %) vs. 36.26 % (75.55 %); all P> 0.05]. Conclusion The methylation status of RAP1GAP promoter maybe associate with genesis and development of colon cancer, which might be used as a target for early diagnose of colon cancer.

To explore the associations between the presence of bacteria and virus in the nasopharyngeal secretions, and wheezing, condition and hospitalization period in infants with community acquired pneumonia. Methods Clinical data, inclu-ding detection of bacteria and viruses, conditions and hospitalization period, of 1106 hospitalized infants with community ac-quired pneumonia from March 2009 to February 2010 were retrospectively analyzed. The infants were classiifed into wheezing (697 cases) and non-wheezing (409 cases) groups. Results Viruses were detected in 540 infants (48.8%), and the total detection rate of viruses and detection rate of respiratory syncytial virus in wheezing group were signiifcantly higher than those of non-wheezing group (P=0.000). Bacteria were detected in 590 cases (53.3%) and no signiifcance was found between two groups (P=0.821). The detection rate of Streptococcus pneumonia was higher in wheezing group than that of non-wheezing group (P=0.038). Comparing to the infants detected with both viruses and bacteria, no signiifcances were found in the occurrence of severe pneumonia and hos-pitalization period in those infants detected with viruses only (P>0.05), as well as in the wheezing time of period (P>0.05). Con-clusions Wheezing in infants with community acquired pneumonia is related to the infection of viruses, especially to respiratory syncytial viruses. Virus infection accompanying bacterial infection has no impact on duration of hospitalization and wheezing. The infection of Streptococcus pneumonia may relate to wheezing in infants.

Objective To investigate the expression of signal-induced proliferation-associated gene 1 (SIPA1), Ezrin and E-cadherin (E-cad), and their relationship with clinical patterns in epithelial ovarian carcinoma.Methods Immunohistochemistry was used to detect the expression of SIPA1, Ezrin and E-cad in normal ovarian tissue, benign epithelial ovarian tumor, borderline epithelial ovarian tumor and epithelial ovarian carcinoma,respectively. Results The positive rate of SIPA1 expression was 44.2 % (23/52), 64.5 %(20/31), 93.3 % (28/30) and 100.0 % (15/15) in epithelial ovarian carcinoma, borderline epithelial ovarian tumor, benign epithelial ovarian tumor, and normal ovarian tissue, respectively, and there was a statistical difference (χ2 = 29.159, P= 0.000). The corresponding rates were 57.7 % (30/52), 61.3 % (19/31), 90.0 %(27/30) and 93.3 % (14/15) for the positive rate of Ezrin expression (χ2= 14.555, P= 0.002), as well as for 23.1 % (12/52), 58.1 % (18/31), 86.7 % (26/30) and 0 (0/15) for the positive rate of E-cad expression, respectively (χ2= 45.731, P= 0.000). In patients with epithelial ovarian carcinoma, the expression of SIPA1 was correlated with tumor differentiation (χ2=3.895, P=0.048), but not with histological type and clinical stage (all P>0.05). The expression of Ezrin was not correlated with histological type, tumor differentiation and clinical stage (all P>0.05). There was a positive correlation between expression of E-cad and SIPA1, Ezrin in epithelial ovarian carcinoma, respectively (r= 0.339, P= 0.014; r= 0.284, P= 0.041), but no correlation between the expression of SIPA1 and Ezrin (r= 0.214, P= 0.128). Conclusions SIPA1, Ezrin and E-cad play important roles in the occurrence and development of epithelial ovarian carcinoma. They cooperate in the progression and their combined detection can better evaluate the prognosis of epithelial ovarian carcinoma.

Background and purpose: Docetaxel plus prednisone chemotherapy can improve the patients' survival for castrate-resistant prostate cancer. Angiogenesis inhibitors can also inhibit the growth of tumor. The curative effect of combined treatment is still not clear. This study aimed to evaluate the efficacy of docetaxel plus prednisone combined with thalidomide in treating castrate-resistant prostate cancer (CRPC) patients with bone metastasis. Methods:A total number of 78 CRPC patients were selected in Fuzhou General Hospital from Dec. 2008 to Jun. 2015. Seventy-eight patients were divided into two groups: 40 patients in chemotherapy group (docetaxel plus prednisone) and 38 patients in combined treatment group (docetaxel plus prednisone combined with thalidomide). A total number of 78 subjects were evaluated by the effective rate, the remission rate of bone pain, the prostate specific antigen (PSA) progression-free surviv-al, the overall survival and adverse effect. Results: The response rate (65.79%) and the remission rate of bone pain (86.84%) in combined treatment group were both higher than those in chemotherapy group (40.00% and 60.00%, P<0.05). The PSA progression-free survival (4.13 months), progression-free survival (4.25 months) and the overall survival (18.06 months) in combined treatment group were all longer than those in chemotherapy group (3.54, 3.75 and 16.26 months). The PSA pro-gression-free survival was significantly longer in combined treatment group (P<0.05). There was no significant difference in the overall survival between two groups (P>0.05). The rates of adverse effects including peripheral neuritis and lethargy in combined treatment group (26.32% and 55.26%) were higher than those in chemotherapy group (5.00% and 17.50%, P<0.05). Conclusion: Thalidomide combined with docetaxel plus prednisone in CRPC patients with bone metastasis can prolong the PSA progression-free survival and overall survival. The adverse effects are mild. It may become a new choice of treatment for CRPC.
