Purpose:To evaluate the effect of biological response modifiers for Ⅲ stage non-small-cell lung cancer.Methods:Fifty-nine patients were randomized into two groups.Twenty-nine patients were put into radiotherapy and chemotherapy(R+C) groups,thirty patients were into Biological response modifiers and radiotherapy chemotherapy(BRMS+R+C) groups.All patients received routine radiotherapy 2.0 Gy per day,5times a week to a total dose of 60-65 Gy,in 42-45 days.Radiation fields just covered clinical tumors.Chemotherapy consisted of cisplatin 25-30 mg/m 2 ,etoposide 50-70 mg/m 2 on days 1?2and 3 every 4 week,for squamous cell carcinoma.For adenocarcinoma,it was mitemycin 4-6 mg/m 2 on day1 and vindesine 3 mg on day1 and8,and cisplatin25-30 mg/m 2 on day1?2 and 3,every 4 weeks interferon-?(IFN-?)and interleukin-2(IL-2)were used in(BRMS+R+C)groups after the second chemotherapy was over. IFN-? was given on days 1?2?3 and IL-2 on days 2?4?6 to a total of forty-eight day.Results:The overall response rate was 51.7% and 76.6% in(R+C) and(BMRS+R+C) groups.The one.two year survival rates were 62.1% 17 3% and 83 3%,43 3% in (R+C) and (BMRS+R+C) groups respectively.Conclusions:The preliminary results from our study has shown that biological response modifiers combined with radiotherapy and chemotherapy for non -small cell lung cancer has better early response rate and survival rate.

A total of 210 female patients with overactive bladder (OAB) were divided into M receptor blockage (M,n =71),pelvic floor muscle stimulation physiotherapy (S,n =70) and combination (C,n =69) groups.After one course of treatment,the OAB symptom scores were compared to pretreatment values (P ＜ 0.05).After a second course,the overall response rate was 69％ in group S.Pelvic floor muscle stimulation physiotherapy provided excellent sustained outcomes.

Objective Molecular targeted drugs have anti-angiogenesis and anti-tumor effects.The study was to investigate the role of sunitinib on treating metastatic renal cell carcinoma ( mRCC) and its long-term efficacy and adverse reactions. Methods From November 2007 to March 2013, 281 mRCC patients were divided into two groups according to their own willingness.102 patients in the experimental group received sunitinib 50 mg per day.Pain score, metastatic focuses before and after targeted therapies were compared.179 patients in control group was treated by immunotherapy.Kaplan-Meier survival analysis was used to draw the survival curves and Cox regression model was applied in multivariate analysis. Results There was no difference between the two groups on baseline (P>0.05).In the experimental group, 78 cases were clear cell carcinoma, with remission rate 29.4%, stablity rate 53.8%and total effective rate 83.2%after treatment;15 cases were papillary renal cell carcinoma, with remission rate 33.3%, stablity ratio 46.7%and total effective rate 80.0% after treatment;9 cases were collecting duct carcinoma, with the remission rate 22.2%, the stablity ratio 55.6% and the total effective rate 77.8% after treatment.The bone scan after 1 cycle of treatment showed 2 cases progressed(10.5%), 5 cases relieved(26.3%) and 12 cases sta-blized(63.2%), the total effective rate of bone metastasis amounting to 89.5%, the effective rate of lung metastasis 81.7%, the effective rate of liver metastasis 60.0%and the effective rate of lymph node metastasis 72.8%.The median overall survival in the experimental group was 28.9 months, 20.7 months in control group(P<0.05).Cox regression analysis showed age, tumor classification, liver, lung, bone and lymph node metastasis were prognostic factors influencing mRCC.The common averse events were white blood cells, thrombocytopenia, neutropenia and hypoalbuminemia. Conclusion Sunitinib for the treatment of mRCC can diminish the metastatic focuses , ease the pain , improve the quality of life, delay the progression of the disease, and prolong the overall survival.

Objective To study the association between metabolic syndrome (MS) and prognosis of endometrioid carcinoma.Methods A total of 256 patients with endometrioid carcinoma at,Zhejiang Cancer Hospital between January,2001 and December,2008 were chosen.The deadline for follow up was December 2008.The general conditions(including age and body mass index),whether coupled with MS and it's risk factors(including waist circumference,fasting plasma glucose,triglycerides,high-densitylipoprotein,systolic and diastolic blood pressure) were analyzed.The outcome of 256 patients whether coupled with MS were analyzed using Kaplan-Meier curve.Relative risks were estimated using Cox proportional hazards regression model.Results A total of 256 cases were followed-up successfully.Sixtyfour (33.0％) cases coupled with MS among the 194 patients survived,while thirty-two (51.6％)coupled with MS from 62 cases died,there was significant difference between them (x2=6.953,P=0.008).The total fiveyear survival rate was 75.8％,the survival time was (78.0±3.4) months.The rate and the survival time of patients coupled with MS [66.7％,(67.0±2.4) months] were significatly lower than those coupled with no MS [81.3％,(85.0±4.0) months;P＜0.05].The Cox proportional hazards regression results showed that coupled with MS,body mass index ≥25 kg/m2,waist circumference＞80 cm,abnormol systolic and diastolic blood pressure,abnormal fasting plasma glucose and more than two components of definitions of MS were related to bad prognosis of endometrioid carcinoma(P＜0.05).Conclusion Metabolic syndrome may be lead to a bad prognosis of endometrioid carcinoma.

Staphylococcus epidermidis is the most important member of the coagulase-negative staphylococci and one of the most abundant colonizers of human skin.S.epidermidis is a bacterial species that is commonly described as relatively innoc-uous,which is in part due to the notion that it lacks secreted toxins with limited capability of infection.S.epidermidis pro-duces a series of molecules that provide protection from host defenses,including many proteins and exopolymers.Further-more,recent research has identified a family of cytolytic peptidesin S.epidermidis,the phenolsoluble modulins (PSMs),and the notion that S.epidermidis is virtually toxin-free had to be somewhat revised.

OBJECTIVE To investigate the productive rate of AmpC ?-lactamases and ESBLs produced by the Gram-negative bacilli from the nosocomial infection in our hospital. METHODS AmpC ?-lactamases and ESBLs were detected by the improved cefotaxime and ceftriaxone three-dimensional test. RESULTS The productive rate of AmpC ?-lactamases was 16.00%.Among them,the productive rate of AmpC ?-lactamases was only 8.84%.The Enterobacter cloacae,Serratia marcescens and Enterobacter aerogenes were easy to produce the enzymes(36.00%,31.25% and 28.00%).The productive rate of AmpC ?-lactamases and ESBLs at the same time was 7.16%. CONCLUSIONS The productive rate of the enzymes by the Gram-negative bacilli from the nosocomial infection is rather high.

Objective To investigate the effect of surgical treatment combined with 131I in the treatment of thyroid papillary carcinoma.Methods45 cases of papillary thyroid cancer patients were selected from January 2008 to January 2012 in our hospital.All of the patients were treated with total thyroidectomy surgical,postoperative underwent thyroid hormone and 131I radionuclide therapy,The patients were followed up.ResultsAt 3 months or 6 months after operation,the levels of serum P53,Fas and TNF-a were significantly higher than immediate time after surgery (P<0.05) and cyclin E protein levels were significantly lower than immediate time after surgery (P<0.05).There were no difference of serum P53,Fas,TNF-and Cyclin E protein levels between at 3 months and 6 months after operation.During five years of follow-up, the 5-year recurrence rate of 4.4%,and the distant metastasis rate was 2.2%.ConclusionOperation combined with 131I radionuclide therapy has good clinical results,could be used as the first choice for clinical treatment.

ObjectiveTo investigate the proliferation of rat's osteoblasts promoted by mechanical strain via the protein kinases C ξ(PKCξ) protein path-way.MethodsOsteoblasts were retrieved from SD rats' skulls in the sterilized environment.BioDynamic testing instrument was used to exert 2％ and 0％ mechanical strain on rats' osteoblasts for 180 min on the each group(2％ mechanical strain was experimental group and 0％ mechanical strain was control group); and the same method was applied on the rats' osteoblasts which pretreated with the classical PKC ξ inhibitor with 2％ mechanical strain (inhibitor group).The cell cycles of rats' osteoblasts were measured by flow cytometry; and Western blotting and immunofluorescence were used to detect expression of protein PKC ξ and phosphorylationed PKC ξ in the rats' osteoblasts.ResultsThe mechanical strain obviously increased the ratio of S period in the cell cycles.Compared to the control group and inhibitor group,a significant increase of the expression of protein PKC ξ and phosphorylationed PKC ξ in the osteoblasts was detected in the mechanical strain experimental group.ConclusionPKCξ can respond to the stimulus of the mechanical strain,which promotes the proliferation of osteoblasts through PKCξ pathway.And it plays an important role in the process of signal conduction.

Objective To explore the optimal b value in MR DWI for breast.Methods Forty patients with palpable masses of breasts underwent MR and DWI at b = 1000, 800 and 600 s/mm2 before surgery according prospective planning. Visual assessment, signal to noise ratio (SNR) of DWI and the ADC values of benign and malignant lesions were compared among three b values using one-way ANOVA test.The diagnostic value of ADC were analyzed by ROC curves.Results Of the 40 patients, there were 26 patients with malignant lesions and 14 patients with benign lesions verified by histopathology.36 patients with 42 lesions were examined by DWI, and detectabilities at three b values were alike.Most DWI at b = 1000, 800 and 600 s/mm2 were of high quality, and images of grade A were 75.0% (30/40), 77.5% (31/40) and 77.5% (31/40), respectively.Mean SNR at b = 1000, 800 and 600 s/mm2 were 63 ± 22,82 ± 27 and 96 ± 29 respectively.Compared with one another, there was statistically significant difference (P <0.01).Mean ADC of benign lesions at different b values were (1.44 ± 0.28) × 10-3, (1.50 ± 0.32) × 10-3 and (1.52±0.29) × 10-3 mm2/s respectively. Compared with one another, there was no statistically significant difference (P = 0.725).Mean ADC of malignant lesions were (1.00 ± 0.25) × 10-3, (0.98 ± 0.19) × 10-3 and (1.07 ± 0.22) × 10-3 mm2/s respectively.Compared with one another, there was also no statistically significant difference (P = 0.358).The area under the ROC curves at b = 1000,800 and 600 s/mm2 were 0.879,0.885 and 0.865 respectively.Threshold value to distinguish benign and malignant lesions were 1.295 × 10-3,1.435×10-3 and 1.335×10-3 mm2/s respectively.Sensitivity of diagnosing breast cancer were 80.0%, 92.0% and 84.0%, and specificity were all 90.0% . Positive predictive values were 95.2%, 95.8% and 95.5% at b = 1000, 800 and 600 s/mm2.Conclusion Combining SNR and the value of ADC in diagnosing benign and malignant breast lesions, the study indicated that b = 800 s/mm2 was the optimal b value in breast DWI.
