The core event of cell proliferation is DNA replication and cell division. DNA topoisomerase type Ⅱ plays an important role in this process.As a cell proliferating marker,DNA topoisomerase type Ⅱis caught great attention. The authors review the recent research of NDA topoisomerase type Ⅱ and its value evaluated as a cell proliferating marker.

Objective To investigate the killing effect of allitride on fungus inside Candida albicans biofilm (BF) .Methods The polyascchride components of BF was labeled by FITC-conA .The fluorescence microscopic was adopted to observe the effect of al-litride on the BF forming process of Candida albicans in morphology .The specimens were divided into 3 groups ,the control group (allicin concentration of 0) ,0 .25 mg/mL allicin group ,0 .5 mg/mL allicin group ,1 .0 mg/mL allicin group ,2 .0 mg/mL allicin group .The XTT reduction assay was performed to quantitatively detect the killing effect of allitride on fungus inside Candida albi-cans BF .Results After the treatment by different concentrations of allitride ,the BF structure was observed by fluorescence micros-copy .The fluorescence intensity of high concentration group was weakened compared with the low concentration group and the con-trol group .The ODA450 values of the XTT reduction assay after acting on Candida albicans BF for 5 h by different concentrations of allitride (0 .5 ,1 .0 ,2 .0 mg/mL) were 1 .87 ± 0 .31 ,1 .64 ± 0 .25 and 1 .30 ± 0 .29 ,respectively ,and the OD450 value of the control group was 2 .11 ± 0 .26 ,there was statistically significant difference between the allitride groups and control group (P<0 .05);after acting on Candida albicans BF by 0 .25 mg/mL allitride ,the OD450 value was 1 .93 ± 0 .31 ,the difference had no statistical signifi-cance compared with the control group(P>0 .05) .Conclusion Allitride can kill the fungus inside BF of Candida albicans and has the inhibiting effect on biofilm .Moreover the inhibiting effect on biofilm is increased with its concentration increase within certain concentration range .

High grade B-cell lymphoma (HGBL) has been defined as a separate entity in World Health Organization classification in 2016 and is considered to be clinically aggressive. People make continuous analysis of the subgroups and accurate treatments, such as the comparison between the prognosis of HGBL-not otherwise specified and double-hit lymphoma (DHL), transformed and primary DHL, myc partner/bcl-2/bcl-6 translocation, TP53 expression, serum albumin, chemoimmunotherapy, hematopoietic stem cell transplantation, T cells with chimeric antigen receptors therapy, etc. This report will address the progress of HGBL prognosis and therapy in the 58th American Society of Hematology Annual Meeting.

Objective:To obtain the optimal conditions for separating catalpol from leaves of Rehmannia by selecting appropriate macroporous adsorption resins.Methods:The detection indication was the content of catalpol, which was determined by HPLC method. Twelve different kinds of macroporous adsorption resins were studied on the static capacity of adsorption and desorption, and H103 resin was selected for the research of separation and purification.Results:The H103 resin had a good capacity for adsorption and desorption.The best process of purifying catalpol by H103 resin was 1mg/ml concentration, the adsorption rate of 1-2 BV/h,the flow rate of 1-3 BV/h, and 8 BV with 10% alcohol.Conclusion:The method is simple and available, which can simplify the production process and lower costs.

Objective: To investigate the cause and mechanism of oral lichen planus (OLP). Methods: The expression of cyclins dependent kinases (CDK4) in epithelial cells in the samples in 40 cases of OLP and in 10 cases of healthy controls was observed by immunohistochemical method. Results: The expression indexes of CDK4 in the epithelial basal layer and spinous layer in OLP were 0. 5637 ? 0. 0201 and 0. 5388? 0. 0120, those in the healthy control were 0. 4020? 0. 0155 and 0. 3480? 0. 0163, respectively(p

Purpose:To study the expression of CD 44 V 5 and Nm23 H 1 gene products and their significance in esophageal cancer patients.Methods:The expression of CD 44 V 5 and Nm23 H 1 in 85 cases of formalin fixed, paraffin embedded specimens of esophageal cancer were measured by immunohistochemistry S P method. Fifty cases were followed up for 3 years after operation.Results:①The positive expression rate of CD 44 V 5 and Nm23 H 1 was 61.2% 、57 6%, respectively in esophageal cancer.②Overexpression of CD 44 V 5 gene products were closely related with the invasive extent , histopathologic classification , TNM stage ,lymph node metastasis(LNM) and prognosis of Ec( P

OBJECTIVE:To discuss what service marketing strategies the pharmaceutical enterprises in China should choose in the face of more and more fierce competition in pharmaceutical markets.METHODS:The service characteristics of both prescription drugs and over-the-counter(OTC)drugs were analyzed and new conceptions in pharmaceutical marketing such as the development and application of the service marketing were introduced as well.RESULTS&CONCLUSION:Di?versity,standardization,materialization are the right way the pharmaceutical enterprises should follow in the prescription drugs services;however,standardization,mechanics,brands are necessary for the OTC drugs services.

Objective To screen for clopidogrel metabolism related gene CYP2C19 in patients with coronary artery disease in Wuhan.Methods 316 patients,from Jan to Dec 2014,after cardiology percutaneous coronary interventional therapy (PCI) for the treatment of coronary artery disease were selected as research object.Clopidogrel metabolism related CYP2C19 geno-types (* 1,* 2,* 3)were detected by the gene chip,and for different types of metabolism of patients according to CYP2C19 gene type:strong metabolize type (*1/*1),intermediate metabolizer types (*1/*2,*1/*3),poor metaboli-zer types (*2/*2,*3/*3,*2/*3).Results According to the CYP2C19 gene polymorphism of metabolic function type, strong metabolic type carrying CYP2C19*1 (*1/*1)accounted was 43.4%,intermediate metabolizers carrying CYP2C19*2 or *3 (* 1/* 2 and * 1/* 3)and poor metabolizers (* 2/* 2,* 2/* 3 and * 3/* 3)accounted was 42.4% and 14.2%,respectively.Different gender had no statistical significance in CYP2C19 genotype differences.Conclusion Clopi-dogrel metabolism functional of CYP2C19 gene in patients with interventional coronary heart disease in Wuhan area had more deletion gene.

Objective To evaluate non operative and simple operative managements of the calcaneal fractures. Methods 97 patients with calcaneal fractures were treated by non operative management or percutaneous reduction with wires or screw fixation from April 1997 to December 2001 in our department. They were followed up for more than 2 years. 64 patients were treated with non operation, 27 were fixed with wires and 6 with screws. Results 23 patients had excellent results, 67 good, 5 fair and 2 poor. The total good and excellent rate was 92.7%. 2 patients experienced secondary arthrodesis 1 year after injury. Conclusion Although the calcaneal fractures can be treated satisfactorily with non operative management or percutaneous reduction with wires or screws fixation, further prospective and comparative studies should be done in clinic to determine whether the calcaneal fractures should be treated with open reduction and fixation or with simple operative management.
