ABSTRACT
Objective To study the application value of ultrasound(US) examination for evaluating the knee joint status in the patients with hemophilia.Methods The US examination data of 44 patients (70 knee joints) with hemophilia were collected,among them 11 cases aged below 18 years old,16 knee joints completed the MRI examination,meanwhile the knee joint health status was evaluated by adopting the 2.1 version of hemophilia joint health assessment (HJHS) form.Then the correlation between the US score with the age and bleeding times and the relation between MRI score with HJHS score were analyzed.Results The severity of hemophilia arthropathy had no obvious correlation with hemophilia severity (F=0.013,P =0.987).With the age increase and bleeding frequency increase,the knee joint lesion was aggravated.The detection of early synovial thickening and cartilage change in arthropathy had no obvious difference between US and MRI examinations(P＞0.05);the obvious correlation existed among US score,MRI score and HJHS (P＜0.05).Conclusion US has an important significance for the early diagnosis of hemophilic arthropathy.

ABSTRACT
Objective To investigate the role of thrombelastography(TEG) in assessing the risk of bleeding and diagnostic value in patients with acute leukemia(AL) .Methods The TEG and PLT data were counted in 127 patients(272 sets of data) who were diagnosed with AL .Those patients were divided into two groups :group 1 (including patients with bleeding) and group 2 (in‐cluding patients with no bleeding) .The indicators(R values ,K values ,α‐angle ,MA values)and PLT count were compared between two groups .Those data with PLT0 .05);the are‐as under the ROC curve about the PLT counts ,MA value andα‐angle were more than 0 .5 (0 .750 ,0 .740 and 0 .653) .Conclusion T EG could predict the risk of bleeding in acute leukemia patients and it could be used in clinical application .
ABSTRACT
Objective To observe the positive rate of plasma cytomegalovirus DNA(CMV‐DNA) level after allogenic hema‐topoietic stem cell transplantation (allo‐HSCT) ,analysis and explore the risk factors related to CMV infection .Methods Choose 30 patients who had performed allo‐HSCT in our department from July 2012 to September 2014 .PCR were used regularly to detect the plasma CMV‐DNA levels in these patients .The regular monitoring times were as follow :the first month(once a week) ,the second to third month(twice a week) ,the fourth to sixth month(once a month) after allo‐HSCT respectively .The positive rates were coun‐ted in every period .Results Thirteen patients had CMV infection ,and the infection rate were 43 .3% .In the first month ,there were 4 cases (13 .3% )whose plasma CMV‐DNA levels were positive ,however ,the positive cases in the second month ,the third month , the fourth month ,the fifth month and the sixth month were 11(36 .7% ) ,2(6 .7% ) ,0 ,2(6 .7% ) and 0 respectively .Statistical data showed that it was in the second month after allo‐HSCT that the CMV‐DNA positive rate was higher than other periods .The anal‐ysis suggested that the positive rate of CMV‐DNA related to the administration of rabbit anti‐human thymocyte globulin(ATG) ,ba‐siliximab ,and the occurrence of acute graft versus host disease(GVHD) ,there were no relationship among gender ,age ,risk stratifi‐cation of primary disease ,HLA condition ,preparative project ,recovery time of neutrophile granulocyte .Conclusion It is necessary and beneficial to monitor blood CMV‐DNA level regularly and take treatment early to avoid CMV related comobidity after allo‐HSCT .
ABSTRACT
Probing into the methods and techniques of physician-patient communication is important to clinic medicine and medical education. Physician- patient shared decision is one of important aspects of physician-patient communication, 80 patients with hematologic malignancies were reviewed for classification of models of medical decision making, and the methods and techniques of physician-patient shared decision were also discussed .
ABSTRACT
Endocrinology is a new and important medical science.Owing to the great development of modern scientific revolution,it improves quickly.However,the development of endocrinology abides by the laws of epistemology and dialectics.It embodies not only the practicality,penetration,creativity of the scientific cognition,the law of the unity of oppositeness in the growth of the object,but also the high unity of comprehension and analysis of the cognition.
ABSTRACT
Attentions have been paid to the medical teaching for foreign students in China.The preliminary experiences of teaching of physical diagnostics for foreign students are reviewed from the aspect of foreign students,selection of textbooks and tutors.Moreover,how to teach theory class and practice class are discussed.Many problems of teaching need to be analyzed and solved in the future.
ABSTRACT
Background and purpose:hTERT is indistinct in the effect of neo-adjuvant chemotherapy. Our aim was to detect both expression of hTERT mRNA and protein in breast cancer tissue and their changes after neoadjuvant chemotherapy. Methods:From Feb 2004 to Jun 2007, 53 cases with untreated advanced breast cancer were enrolled. All patients received CEF chemotherapy three cycles. The breast cancer tissue was collected before and after chemotherapy. hTERT mRNA and protein expression were detected by RT-PCR and immunohistochemistry techniques. Results:The positive hTERT mRNA and protein expression in breast cancer tissue before chemotherapy were 77.4% and 73.6% respectively, and after neo-adjuvant chemotherapy were 28.3%,22.6% respectively.The effective rate of the neo-adjuvant chemotherapy of the patients with positive of hTERT expression was higher than those with negative hTERT expression. Conclusion:The chemo-agents altered hTERT gene expression, improved negative rate of hTERT expression. Detecting expression of hTERT gene in breast cancer tissue would be an important index for predicting the effects of neo-adjuvant chemotherapy.
ABSTRACT
Objective:To construct a recombinant prokaryotic expression vector pQE30-hALRIP for further research.Method:PCR was used to amplify hALRIP codon region.The gene was inserted into pMD18-T vector and sequenced.Then the prokaryotic expression vector pQE30-hALRIP was constructed and identified. Results:Clonal recombinant vector pMD18- hALRIP and expression vector pQE30-hALRIP were constructed. DNA sequence analysis and restriction analysis showed both of the vectors were the same as the predicted results. Conclusion:Prokaryotic expression vector pQE30-hALRIP is successfully constructed.
