Objective To investigate the clinical features and treatment of aggressive angiomyxoma of the genitourinary system. Methods Two cases of aggressive angiomyxoma of the genitourinary system were reviewed. One case was a 55 year old man.He presented with a painless inguinal mass which was indicated in low echo by ultrasound;and he underwent surgical complete excision.The other case was a 14 year old female presenting with frequent urination,hematuria,dysuria and urethral mass.After the IVU,CT and 3 dimensional CT examination revealed the extent and blood supply,partial cystectomy and ureteroneocystostomy were performed on her. Results The 2 patients were followed up for 2 to 6 months after surgery,with no recurrence and metastasis.Case 1 was diagnosed with aggressive angiomyxoma involving the spermatic cord and the immunohistochemical testing was positive for Vimentin and SMA,negative for Desmin and S 100.Case 2 was diagnosed with aggressive angiomyxoma of the urinary bladder and the immunohistochemical testing showed that the cancer cell was positive for CD 34 ,SMA,Vimentin,and negative for Desmin,Caldesmon,ER,PR and S 100. Conclusions Aggressive angiomyxoma is a rare,benign and locally aggressive neoplasm.The histopathologic and immunohistochemical studies reveal the definite diagnosis.The therapy is surgical excision as complete as possible.Radiotherapy combined with endocrinotherapy may be used for recurrence and difficult excision of the tumor.Long term follow up and close monitoring with imaging techniques are essential for timely identification of recurrence and for prompt resection.

Objective To evaluate the short-term therapeutic effect and radiation reaction of stereotactic radiotherapy for early stage non-small cell lung cancer in the elderly patients. Methods Thirty-one patients with stage Ⅰ - Ⅱ non-small cell lung cancer were treated with stereotactic radiotherapy. Patients aged 70-88 years, median age 76; 21 were stage I patients, and 10 stage Ⅱ ; 14 patients had tumor

Objective To investigate the effect of morphine combined with cisplatin on inva-sionon and migration of human lung adenocarcinoma cell A549.Methods Human lung adenocarcino-ma A549 cells were inoculated on cultured for 24 h,then were randomly divided into 5 groups:control group (group CON),cisplatin group (group CIS),morphine 0.3 μg/ml+ cisplatin group (group MT1),morphine 3 μg/ml+ cisplatin group (group MT2),morphine 30 μg/ml+ cisplatin group (group MT3).Cisplatin concentration was 4μg/ml.Each group was medicated immediately after 48 h incubation,invasion detection cells by Transwell assay,cell scratch assay cell migration ability, Western-blot detection of matrix metalloproteinase-2 (MMP-2),the expression of MMP-9,Ezrin protein and Fascin protein.Results Compared with group CON,group CIS and morphine combined with cisplatin group reduced tumor cell invasion and migration ability,group MT3 and CIS down-reg-ulated MMP-2,MMP-9,Ezrin and Fascin expression (P<0.05).Compared with group CIS,com-bined with cisplatin group enhanced tumor cell invasion and migration ability group MT3,up-regula-ted MMP-2,MMP-9,Ezrin and Fascin expression (P<0.05).Conclusion Morphine may dose de-pendently reduce cisplatin on invasion and migration of human lung adenocarcinoma cell line A549, and up-regulation of MMP-2,MMP-9,Ezrin,Fascin expression is one of its possible mechanisms.

Transforming growth factor-?1 (TGF-?1) was reported to play an important role in the pathogenesis of asthma in many stu-dies.It can stimulate the growth of fibroblast and give rise to fibrosis of lung tissues.Many scholars think that TGF-?1 is closely related to airway remodeling.It is a breakthrough to aim at TGF-?1 to find a way to intervene remodeling in asthma.Glucocorticoid (Dexamethasone and Budesonide) can have an impact in some extent to airway remodeling.In addition,interferon-? and some traditional chinese medicine such as ligustrazine,tripterygium wilfordii and ginkgo maybe effective,they all may ameliorate the progression of airway remodeling following redu-cing partial airway TGF-?1 expression.

OBJECTIVETo investigate the effects of ethyl acetate extract of Huanglian Jiedu decoction (EAHD) on hyphae development of Candida albicans.

METHODInverted microscope, fluorescence microscope, SEM were applied to inspect the Morphological change of C. albicans treated by EAHD at different concentrations. Solid agar plate was utilized to evaluate the colony morphology. Quantitative Real-ime PCR(qRT-PCR) was adopted to observe the expression of hyphae-specific genes such as HWP1, ALS3, UME6, CSH1, SUN41, CaPDE2.

RESULTEAHD with concentration of 312 and 1 250 mg . L-1 could inhibit formation of hyphae and colony morphology. The expression of HWP1, ALS3, UME6, CSH1 were downregulated 4. 13, 3. 64, 2. 46, 2. 75 folds ,while the expression of SUN41 were upregulated 7. 26 folds, CaPDE2 keep unchanged.

CONCLUSIONEAHD could inhibit formation of hyphae and colony morphologies of C. albicans through downregulating HWP1, ALS3, UME6 and CSH1.

ObjectiveTo investigate the clinical biocharacteristics,treatment,prognosis and the factors that influence prognosis of anaplastic thyroid carcinoma(ATC). MethodsThe clinical data of 108 ATC patients treated at our institution from January 1981 to April 2009 and follow-up results were retrospectively reviewed.ResultsThe median survival time of 108 patients was 6 months.The overall 1-year,2-year,5-year survival rate was 40.3％,30.9％ and 21.9％ respectively.Univariate analysis showed the factors influencing the prognosis of ATC patients were tumor size, distant metastases, stage,leukocytosis, radiotherapy, localresection, postoperativeradiotherapyandmultimodalitytherapy.Multivariate analysis indicated that tumor size,stage,leukocytosis and radiotherapy were independently associated with the prognosis.ConclusionsAnaplastic thyroid carcinoma is rare but highly aggressive malignancy with poor prognosis. ATC patients should receive multimodality therapy,especially local resection and postoperative radiotherapy.Even inoperable patients could benefit from radiotherapy.

Objective To evaluate the efficacy and tolerance of preoperative concurrent chemoradiotherapy in the treatment of locally advanced middle-low rectal cancer.Methods From June 2007 to June 2013,51 untreated patients with histopathologically proven rectal cancer (T3/T4 or N (+))were included in this study.Three-dimensional radiotherapy was delivered to the whole pelvic cavity at 45.0-50.4 Gy/25-28 fractions.Two cycles of chemotherapy with FOLFOX4 or XELOX were given concurrently at weeks 1 and 4 of radiotherapy.Surgery was performed at 4-8 weeks after chemoradiotherapy.Adjuvant chemotherapy with FOLFOX4 or XELOX was given within one month after surgery.The Kaplan-Meier method was used to calculate survival rates,and the log-rank test was used for univariate analysis;the Cox regression model was used for multivariate prognostic analysis.Results Fortynine patients completed the preoperative chemoradiotherapy and surgery.The median follow-up was 2.9 years.The overall sphincter preservation rate was 65％;the overall downstaging rate was 59％.Ten (20.4％) of all patients achieved a pathologic complete response (pCR).Grade ≥3 toxicities occurred in 25％ of all patients,and the overall postoperative complication rate was 31％.The 3-and 5-year sample sizes were 24,12,respectively.The 3-and 5-year overall survival rates were 81％ and 69％,respectively;the 3-and 5-year disease-free survival (DFS) rates were 76％ and 60％,respectively;the 3-and 5-year local recurrence-free survival (LRFS) rates were 78％ and 70％,respectively;the distant metastasis-free survival rates were 82％ and 74％,respectively.The multivariate analysis showed that tumor downstaging was an independent prognostic factor for 5-year DFS and LRFS.Conclusions For locally advanced middle-low rectal cancer,preoperative radiotherapy with concurrent FOLFOX4/XELOX chemotherapy can increase pathologic downstaging rate,pCR rate,and sphincter preservation rate.Patients with tumor downstaging may have a better survival advantage.
