Objective To observe the oncololigcal and cosmetic outcomes and complication of breastconserving surgery and radiotherapy for early breast cancer. Methods A total of 78 early breast cancer patients, who were treated in the First People's Hospital of Pingdingshan between January 2001 and September 2008, were identified and followed. Among them, 36 were in stage Ⅰ and 42 in stage Ⅱ. Tangential irradiation was used with a dose of 50 Gy. Tumor bed received a boost dose of 10 Gy electron beam. For axillary lymph node-positive patients, ipsilateral supraclavicular field was hybrid irradiated with 50 Gy X and electron beam.Results The total follow-up ranged from 6 to 98 months. Local recurrence was observed among 4.9% of the patients. The 3-year and 5-year overall survival rate were 96.6% and 92.7% ,respectively. The breast cosmetic satisfaction rate was 94.9%. The main complications reported were acute skin reaction and upper limb edema.Conclusion Breast-conserving surgery and post-operative radiotherapy in early breast cancer patients can lead to satisfactory survival rates and cosmetic effects and hence improved life quality.

Objective To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) and anti-cyclic citrullinated peptide (anti-CCP) antibodies for ankylosing spondylitis (AS), and to establish a new diagnostic method of AS based on anti-citrullinated protein/peptide antibodies (ACPAs) detection.Methods Totally 121 AS patients(AS group), 97 rheumatoid arthritis(RA) patients (RA group)and 103 healthy people(control group) were enrolled for the detection of serum levels of anti-MCV and anti-CCP antibodies using ELISA method as a diagnostic test .HLA-B27 in AS patients was tested by flow cytometry , and RF-IgM in RA and AS patients was detected by immune rate nephelometry .Receiver operating characteristics ( ROC) curve was used to analyze the diagnostic value and to determine the cut-off value.Anti-MCV and anti-CCP antibodies among each group were compared by Mann-Whitney U test, Chi-square test or Fisher′s exact test was used to compare positive rate .Results The anti-MCV levels in AS group [11.60 ( 12.36-25.83 ) U/ml ] were significantly higher than control group [ 11.60 ( 8.41 -13.54)U/ml ],U=2 413,P <0.001, while the levels of anti-CCP had no difference between the two groups [AS group 6.22 (4.30 -8.07) U/ml], and control group [6.01 (3.77 -7.58) U/ml], respectively;U=5 421,P=0.094.The calculated area under the ROC curve of anti-MCV was 0.806,and 14.67 U/ml was the optimal cut-off value with sensitivity of 0.645 and specificity of 0.942.In both HLA-B27 positive and negative AS patients , anti-MCV antibodies levels and positive rate were significantly higher than control group using new cut-off value above (U =133.5, P =0.001; U =2 279.5,P <0.001). Sensitivity of the combination detection of anti-MCV and anti-CCP ( MCV+CCP-) or RF-IgM ( MCV+RF-) were 60.3%(73/121), 62.8% (76/121) and specificity were 89.7% (87/97), 90.7% (88/97) respectively in differential diagnosis of AS and RA , which were significantly higher than anti-MCV detection alone in specificity (16.5%,16/97).Conclusions Anti-MCV could be a new biomarker for the diagnosis of AS .With high sensitivity and specificity , anti-MCV has an equal diagnostic efficiency in HLA-B27 positive and negative AS patients using our new cut-off value.Additionally, the combination detection of anti-MCV and anti-CCP or RF-IgM could be an effective method for differential diagnosis of AS and RA .

Objective To screen 8 series of LY compounds, c-Met tyrosine kinase inhibitors, and evaluate their anti-tumor effects in vitro and in vivo. Methods Preliminary screening was carried out by detecting the c-Met kinase phosphor?ylation inhibition activity of the compounds. CCK-8 assay was adopted for secondary anti-tumor screen of the selected com?pounds using MKN-45, U87MG, Caki-1 and PC-3 cell lines in vitro. The transplanted tumor model of U87MG cells in nude mice was established to evaluate the antitumor activity in vivo. Results Four compounds (LY22, LY25, LY28 and LY32) with better activities were selected by HTRF method, in which LY28 had better inhibitory effect on c-Met than that of Crizo?tinib. The above active compounds showed different degrees of inhibition on the four kinds of target cells (MKN-45, U87MG, Caki-1 and PC-3) detected by CCK-8 method, and the inhibitory effect of LY28 showed the most obvious. Antitumor activi?ty in vivo showed that LY28 can significantly inhibited tumor growth in a dose-dependent manner. The tumor inhibitory rate in high-dose of LY28 was 78.13%. Conclusion The compound LY28 has good antitumor activity in vitro and in vivo, which will be a new tyrosine kinase inhibitor.

[Objective] To observe the preventive effect of Huanglian Jiedu Decoction (HJD), a prescription with the actions of clearing heat and removing toxicity, on rabbits atherosclerosis (AS) induced by Chlamydia pneumoniae (CP) infection. [Methods] Fifty two New Zealand rabbits were fed with forage containing 2. 5g/kg cholesterol and were infected with CP via nasopharynx for three times during 6 weeks. At the end of the sixth week, forty four rabbits with serum CP-IgG positive were randomized into 4 groups: group A treated with HJD 2g?kg-1 ?d-1 by gastric gavage, group B with HJD 1g?kg-1?d-1, group C with azithromycin 20 mg?kg-1?d-1 and model group D with normal saline for 6 weeks. Group E was set up in 8 rabbits fed with fatty forage and served as the control. Serum levels of high-sensitive C reactive protein (hs-CRP) and CP-IgG were detected before infection, after infection and after treatment. At the end of the 18th week, the rabbits were executed and the pathological features of aortic tissue were observed under microscope. Meanwhile, the expression of CP-DNA and tumor necrosis factor ?(TNF-?) in the aortic tissue was detected with polymerase chain reaction (PCR) and immunohistochemical method respectively. [Results] At the end of the experiment, atherosclerotic changes were obvious in groups D and E, particularly in group D. Compared with group D, the atherosclerotic damage was much relieved, and AS indexes such as maximum intimal thickness (MIT), atherosclerotic damage percentage and plaque area index were much improved in groups A and C (P
