Objective To investigate the correlation between the relapse of condyloma acuminatum(CA)and the potential capability of tumor necrotic factor (TNF) production of the host′s peripheral blood leukocytes. Methods Forty-two CA patients and 58 normal controls were enrolled in this study. CA relapse was diagnosed clinically. EB virus-transformed B lymphoblastoid cell line(LCL)were used as TNF producing cells. The TNF producing capability of LCL was measured by bioassay using L929 (a TNF sensitive tumor cell line) as target cells. The LCL were stimulated with LPS to produce TNF. Results The average level of TNF production of LCL from all CA patients (including recurrent and non-recurrent CA patients) was similar to that of normal controls (30.14% ? 12.27 vs 34.06% ? 12.06,P = 0.1136). However, the level of TNF production of LCs from recurrent CA patients was significantly less than that from non-recurrent CA patients (24.75% ? 7.51 vs 36.62% ? 10.96,P = 0.00016). Compared with that of normal controls, recurrent CA patients showed a lower capability to produce TNF (24.75% ? 7.51 vs 34.06% ? 12.06,P = 0.00054), whereas non-recurrent CA patients showed a similar capability to normal controls (36.62% ? 10.96 vs 34.06% ? 12.06,P = 0.3517). Conclusions These results indicate that the cellular immune mechanism might play an important role in the clearance of the residual HPV from the host, in which TNF is involved.

Objective:To evaluate the clinical value and the prognostic factors of postoperative radiotherapy in type B3 thymoma pa-tients. Methods:A total of 159 patients with thymoma were treated by surgery and postoperative radiotherapy. According to Masaoka staging system, 12, 33, 62, and 52 patients had stageⅠ,Ⅱ,Ⅲ, andⅣlesions, respectively. Myasthenia gravis existed in 38 patients. Altogether 58 patients underwent chemotherapy. Overall survival, disease-free survival, and local control rates were calculated by Ka-plan-Meier method. Prognostic factors were analyzed by Cox regression model. Results:With a median follow-up of 52 months (8-125 months), the overall 5-year survival rate was 81.6%. The 5-year progression-free survival rate was 76.2%. The 5-year local control rate was 82.6%. The recurrence rate was 32.6%, and the metastatic rate was 9.3%. In the univariate analysis, tumor size, Masaoka stage, re-section margin, radiotherapy, and chemotherapy were significantly associated with 5-year overall survival and progression-free surviv-al (P<0.05). In the multivariate analysis, Masaoka stage, resection margin, and radiotherapy were independent prognostic factors of 5-year progression-free survival (P<0.05). Radiotherapy could improve the regional control rate and the overall survival of patients in Ma-saoka stagesⅢ-Ⅳ. Conclusion:The major failure mode for type B3 thymoma is the recurrence of pleure. Radiotherapy can improve the regional control rate and the overall survival of patients in advanced stages. Masaoka staging, surgical margin, and radiotherapy are the independent prognostic factors for type B3 thymoma treated by postoperative radiotherapy.

To observe the expression of CD40/CD40L on peripheral blood mononuclear cells (PBMC) in patients with condyloma acuminatum (CA), flow cytometry was employed to examine the expression of CD40 and CD40L on PMBC in 36 patients with CA and 20 healthy controls. Our results showed that mean level of CD40 expression in CA patients was significantly lower than that in the controls (6.58% +/- 2.74% vs 14.81% +/- 6.12%, t = 5.703, P < 0.05); the average level of CD40L in CA patients was also significantly lower than that in the controls (0.73% +/- 0.54% vs 2.67% +/- 2.43%, t = 3.532, P < 0.05). Our results suggest that the reduced costimulatory interaction of CD40 and CD40L in CA patients may be one of the important factors responsible for the low cellular immunity.

A simple,fast and highly sensitive fluorescence analysis method for detection of mercury ion was developed based on N-methyl-mesoporphyrin IX (NMM)/G-quadruplex DNA system and specific T-Hg-T mismatches.In this strategy,a large number of thymine was introduced into guanine-rich oigonucleotides which could form G-quadruplex.In the presence of Hg2+,guanine-rich oigonucleotides and complementary strand could form double-stranded DNA molecule by specific T-Hg-T mismatch pair,leading to destruction of G-quadruplex DNA structure.In the absence of Hg2+,guanine-rich oigonucleotides spontaneously formed G-quadruplex DNA structure that could bound NMM to generate intense fluorescence.Based on the above facts,a sensitive fluorescence biosensor for determination of Hg2+ was fabricated.And the optimal conditions for Hg2+ determination were as follows:buffer solution pH of 6.7,20 mmol/L KCl and 2.5 μmol/L NMM in buffer and incubation for 2 h.Under the optimal conditions,the fluorescence intensity signal change (F0-F) and the Hg2+ concentration exhibited a linear correlation within 50 nmol/L to 1000 nmol/L range with a low detection limit of 22.8 nmol/L (3σ).The biosensor exhibited good selectivity toward common metal ions.The developed method was successfully employed to detect Hg2+ in tap water with recovery of 106.1%-107.8%.
