Objective: To isolate Mycobacterium tuberculosis H37Rv and H37Ra genes especially,and to construct two cDNA libraries by using suppression subtractive hybridization (SSH).Methods: We used suppression subtractive hybridization (SSH) to clone the differential genomic genes between Mycobacterium tuberculosis virulence strain H37Rv and attenuated strain H37Ra.After two times of subtractive hybridization and two times of PCR,the products of last PCR amplification were inserted into pGEM-T Easy vector and be transformed into the E.coli DH5α and screened of blue and white clones of the transformants.The subtracted cDNA library of differentially expressed genes were identified by RT-PCR.Results:High or especially expressed genes as tester had been obtained by SSH in correctitude reaction (H37Rv as tester) and reverse reaction (H37Ra as tester),the cDNA libraries of A and B of Mycobacterium tuberculosis H37Rv and H37Ra were successfully constructed.90% of the colonies were white clones,the single band of the colonies was 75% and 80%.Conchision:The cDNA libraries of Mycobacterium tuberculosis H37Rv and H37Ra were successfully constructed using SSH technique,which lay a solid foundation for screening and cloning new specific differentially expressed genes in them.

Objective:To study the mechanism of protein kinase C regulating CD44 gene expression in vascular endothelial cells.Methods:Human umbilical vein endothelial cells (HUVECs)were taken as study model.The extract of Raf-1 kinase by immunoprecipitation was used for the Western blot analysis,and its activity was determined by enhanced chemiluminescene assay.CD44 gene expression was detected with RT-PCR,and phosphorylation was measurated by autoradiography.Results:CD44 phosphorylation in HUVECs was enhanced by 10ng/ml PMA treatment as compared with untreated cells, which reached the highest level at 30 minutes. Raf-1 kinase activity increased significantly after exposure to 10ng /ml PMA, and 0.05 ?mol/L Calphostinc could inhibit the role of Protein kinase C(PKC). CD44 gene expression level increased obviously after exposure to 10 ng /ml PMA (PKC activator) for only 1 minute(P

Objective To study the changes of cerebral blood flow and cerebral oxygenation during selective head cooling (SHC) in neonates with hypoxic-ischemic brain damage (HIBD). Methods Thirty-eight neonates with moderate and severe HIBD were enrolled in two groups: SHC group (n=18) and normal temperature group (n=20). The gestational age of all subjects were more than 38 weeks and Apgar score in 5 minutes after birth was less than 5 scores. Also, nerve system symptoms and electroencephalogram abnormal was found in 6 hours after birth. Neonates in SHC group had nasopharyngeal temperature maintained 34℃ and in normal trmerature guoup had rectum temperature maintained about 36℃. Seven healthy neonates were as control group. Three groups were observed 84 h. Cerebral blood flow velocity (CBFV) of middle cerebral artery (MCA) was measured with transcranial Doppler (TCD) at 6, 12, 24, 48, 72 and 84 hours after birth. Cerebral cytochrome aa3 (Cytaa3 ) was monitored continuously throughout the study using near infrared spectroscopy (NIRS). Results At 6th hours after birth, Vs [(25. 05?7. 69)cm/s]、Vd [(7. 22?3. 01) cm/s] and Vm [(15. 61?5. 97) cm/s] of MCA and △Cytaa3 in SHC group were lower, and RI (0. 81?0. 15) was higher than control group (P

Objective To establish the rat model of experimental subarachnoid hemorrhage (SAH) and to detect the expression of ADAMTS-4 in early brain injury(EBI) after SAH in rats .Methods Totally 72 adult male SD rats were randomly divided into 2 groups ,the control group and SAH group .The expression of ADAMTS-4 and the content of brain Evans Blue(EB) were detected . The ADAMTS-4 inhibitor α2-macroglobulin was used to study the relationship between the expression of ADAMTS-4 and blood-brain barrier permeability .Results The expression of the mRNA and protein of ADAMTS-4 increased dramatically at 24 h and the contents of EB increased progressively at 12 h after SAH .The protein expression of ADAMTS-4 and the content of brain EB was positive correlated(r=0 .917 ,P<0 .05) .The expression of ADAMTS-4 was inhibited by α2-macroglobulin(P<0 .05) and the con-tents of EB decreased dramatically (P<0 .05) .Conclusion ADAMTS-4 may be involved in the pathological progression of early brain injury after SAH .

The new medical model which is more emphasis on patient-centered concept and the patient's state of mind and mental health has brought a lot of new challenges to medical students who are about to become the medical workers while also put forward new tasks to the medical educational workers.Medical professionalism and doctor-patient communication are very important for the students to handle.Medical professionalism is the professional guidelines of the doctors,which is an important guarantee for the interests of the patients and the embodiment of noble character of doctors.Doctor-patient communication is basal to create a harmonious doctor-patient relationship and is a key means to ensure the medical quality.In addition to lay a solid theoretical foundation,medical students should also learn to establish correct medical professionalism and grasp effective communication skills to become qualified doctor.

AIM To study the influence of four extracts of traditional Chinese medicinal materials(sodium cantharidinate, matrine, cinobufotain and sodium ferlate) on the proliferation of human lung cancer A549 cell line and breast cancer MCF7 cell line;the possible mechanism of sodium ferlate on the inhibition of A549 cells. METHODS The inhibition of cell proliferation was determined by MTT assay and cell cycle was determined by flow cytometry. RESULTS All four extracts of traditional Chinese medicinal materials showed growth inhibition to breast cancer MCF7 cells while only sodium ferlate showed inhibition to lung cancer A549 cells. Synergistic inhibition was found when sodium ferlate was combined with each of the three commonly-used chemotheraputic drugs. Sodium ferlate could induce A549 cell apoptosis. CONCULSION The inhibition of cell proliferation induced is by sodium cantharidinate, matrine, and cinobufotain is quite different between different cancer cell lines. Sodium ferlate can inhibit cancer cell proliferation and show synergistic action while combined with chemotheraputic drugs. The mechanism of sodium ferlate on A549 cell proliferation seem to be related to the cell apoptosis.

BACKGROUND:Although the therapeutic effect of total knee arthroplasty for severe gonarthritis is reliable, deep vein thrombosis also occurred in many patients. Therefore, deep vein thrombosis has been a major reason for unexpected death after total knee arthroplasty. OBJECTIVE:To study the incidence of deep vein thrombosis after total knee arthroplasty with general and epidural anesthesia. METHODS:We searched“PubMed”,“Medline”,“Elsevier”,“Embase”, Cochrane library,“Wanfang”,“China National Knowledge Infrastructure”for papers published from January 2000 to March 2015. The mesh words were“total knee arthroplasty”,“TKA”,“thrombosis”,“DVT”,“randomized control ed trial”,“RCT”for studies concerning deep vein thrombosis after total knee arthroplasty with different anesthetic methods. The double blind method was used for data extraction and assessment of literature quality. Revman5.3 software was utilized to analyze the extracted data using meta-analysis. RESULTS AND CONCLUSION:There were 8 studies including 885 patients. The heterogeneity of the included studies was very low (I2=0, P=0.72). The combined OR was 0.25 (95%confidence interval:0.18, 1.35), indicating that continuous epidural anesthesia in total knee arthroplasty could apparently reduce the possible formation of postoperative deep vein thrombosis. Because of lack of the changes in coagulation factors under general anesthesia and epidural anesthesia, the mechanism underlying epidural anesthesia to reduce the incidence of deep vein thrombosis deserves further investigations. Among patients with deep vein thrombosis, continuous epidural anesthesia could diminish the possible formation of deep vein thrombosis. Thus, epidural anesthesia should be used firstly for knee replacement in patients with high risk of deep vein thrombosis.
