The strain Streptomyces sp.,nominated IMB-14,was isolated from the soil sample of WuDang Mountain by the method of cellulose ester membrane filter.The studies on antibiotic activities,morphological characteristics,cultural characteristics,physiological characteristics,16S rDNA sequence analysis and the metabolite of strain IMB-14 showed that the strain IMB-14 was accordance with Streptomyces xanthoci-dicus.The study on the isolation and identification of strain Streptomyces xanthocidicus establishes a foundation on screening of novel antibacterial and antitumor agents.

Emergency in public health is one major issue relating to the national economy and the people's livelihood.In dealing with the key technologies of detects,diagnosis,disinfection,prevention and control,it is wise to syncretize the correlated subjects in nucleus,chemistry and biology,improve the support condition of teaching,strengthen the reform of teaching contents,add some lessons of emergency treatment,make emergency equipments,and form the ability of rapid diagnosis on the spot and precise identifying in lab,for cultivating the students'capability of spot handling,organization and command,and furthermore exploring and practicing the training pattern of the public heath talent with high quality and emergency ability in our country.

Objective To analyze the characteristics of diagnosis and therapeutic effect of malignant pleural effusion with lung cancer,and explore the prognostic factors and effective diagnosis and treatment plans.Methods A retrospective analysis in-cludes 728 cases of definite pleural effusion with lung cancer from October 2009 to December 2013 in our hospital,which was fol-lowed-up to September 30,2014,and 438 cases were available analyzed.The main outcome measures were incidence,efficiency,pro-gression-free survival and overall survival.Results The overall median progression-free survival and the median survival of malig-nant pleural effusions with lung cancer was respectively 4 months and 8 months.males,small cell lung cancer,massive pleural effu-sion,and right pleural effusion may be the independent factors of local unmanageable malignant pleural effusion by multivariable Lo-gistic regression.The overall survival of pleural effusion with locally control(less than four weeks )was better than those with un-manageable(mOS:9 month vs.5 month,P<0.001).It was no significant difference of the control rate for overall survival prognosis between pleural effusion with two weeks and those with four weeks.histological type,partial remission time,the number of cycles of chemotherapy and TKI therapy may be the independent development risk by progression with Multivariate Cox regression analysis. the progress risk of patients with squamous cell carcinoma and other histological types were lower than that of adeno carcinoma (P=0.007).The progress risk of development of patients with 4 weeks of pleural effusion was significantly lower than that of the non remission (P=0.004),the progress risk of complete chemotherapy cycle number > 2 cycles and takingTKI treatment were significantly reduced (P<0.001;P=0.026).Gender,histological type,pericardial effusion,partial remission time,cycles of chemo-therapy and TKI were the independent prognostic factors for overall survival.The overall survival prognosis of patients with Fe-male,squamous cell carcinoma,no pericardial effusion,and over three cycles of chemotherapy,TKI therapy,and local controlled in 4 weeks was better.Conclusion Male,massive pleural effusion and right pleural effusion are independent predictive factors of local unmanageable malignant pleural effusion.The overall survival of pleural effusion with locally control was better than the patients with refractory control.Histological type,controllable relief time of pleural effusion,cycles of chemotherapy and TKI therapy were the independent predictive factors of progression and overall survival.

Objective To analyze the clinical and CT characteristics of pancreatic metastasis to improve the correct diagnosis rate.Methods The clinical and CT data of 14 patients with pancreatic metastasis were reviewed retrospectively.Results Among the 14 patients,the primary malignancy was lung cancer in 6 cases,renal carcinoma in 3 cases,colon carcinoma in 2 cases,laryngeal cancer in 1 case,gastric cancer in 1 case and ovarian carcinoma in 1 case.Pancreatic metastases from renal carcinomas often developed a long period after initial nephrectomy and survived for a relatively long time.Abdominal CT plain scan and enhanced scan was performed in all cases.Four cases were of solitary type,9 cases were of multiple types and 1 was of diffuse type.Totally 28 lesions were found,which were usually located in the neck and body of the pancreas,the diameter of 28 pancreatic lesions was ranging from 0.5 cm to 11 cm,with a mean diameter of 2.3 cm.On CT plain scan,there were 19 hypodense lesions,7 slightly hyperdense lesions and 2 isodense lesions,5 necrotic lesions.On enhanced CT,the lesions showed moderate enhancement in 7 cases,circular enhancement in 6 cases,moderate and circular enhancement in 6 lesions,obvious enhancement in 8 lesions and no enhancement in 1 lesion.All patients had extra-pancreatic metastases,and 2 cases had peripheral vascular invasion.Conclusions Pancreatic metastases are rare,often accompanied with multiple lesions and extra-pancreatic metastases.The CT features of pancreatic metastases from renal carcinomas are slightly hyperdense and obvious enhancement; in other metastases,there are hypodense,morderate and/or circular enhancement lesions.Accurate diagnosis can be achieved by knowledge of patients' medical history.

Objective To evaluate the predictive value of plasma levels of soluble vascular endothelial growth factor receptor 1(VEGFR-1,also known as sFlt-1) in second-trimester for preeclampsia.Methods One hundred and forty-six pregnant women with normal blood pressure previously were prospectively included in the study.Peripheral venous blood samples were obtained between 20 and 26 gestational weeks.Plasma levels of sFh-1 were measured by an enzyme-linked immunoassay.Results (1) Among 146 previously normotensive women,12 developed preeclampsia (preeclampsia group), 134 remained normal pregnant till the end (normal group).(2) The plasma levels of sFh-1 in preeclampsia group [(4135?699)ng/L] was significantly higher than that in normal group[(1490?1033)ng/L](P

Objective:To predict the secondary structure and B cell epitope of human decay accelerating factor Methods:The accuracy of two secondary structure prediction methods,Chou & Fasman and PHDsec,was compared,and then human DAF secondary structure was analyzed by PHDsec Hydrophilicity scores and solvent accessibility of DAF SCR1 4 were obtained by methods of Hopp & Woods and PHDacc respectively Combined with the secondary structure of DAF,the B cell epitopes in DAF were predicted Results:PHDsec which use multiple sequence alignment,achieve a better prediction accuracy There is no alpha helix in SCR1 4 of human DAF but only beta sheet and loop segments; The computer predicted most possible epitope in DAF localize within amino acid residues Pro73 Val79?Arg130 Leu139 and Glu156 Cys163 Conclusion:These results will be useful in estimate of the epitope and activity sites localized within human DAF

AIM:To investigate the expression pattern of apolipoprotein M (apoM) protein in renal cortex of acute renal failure (ARF) rats with reperfusion. METHODS:Seventy-five male rats were randomly divided into sham operation group (n=25),ARF group (n=25) and pyrrolidine dithiocarbamat (PDTC) group (n=25),five subgroups at time points of 3 h,6 h,12 h,24 h and 48 h after reperfusion were set up in each group. The expressions of apoM in cytoplasm and NF-?B p65 in nucleus of renal cortex were detected at the indicated time points. RESULTS:The expression of apoM in ARF group was obviously higher than that in sham operation group (P
