Circulating tumor cells are closely related to the development and progression of malignant tumors. Current methods of detecting circulating tumor cells include reverse transcription polymerase chain reaction method and immunomagnetic enrichment assay. Detection of circulating tumor cells can contribute to early detection of cancer micrometastases, re-classification of clinical stage, monitoring recurrence and metastasis after surgery or radiotherapy and chemotherapy, predicting prognosis, and selecting personalized therapeutic strategy.

Objective To characterize the medial femoral circumflex artery based on three-dimensional computed tomographic angiography (3DCTA) so as to provide anatomical aids for diagnosis and treatment of hip injuries.Methods To do this research the 3DCTA data of 103 patients (206 hips) were collected who underwent 3DCTA from March 2012 to June 2014 for examination of the pelvis and lower extremities.They were 55 men (mean age,54.7 ± 15.9 years) and 48 women (50.0 ± 16.1 years).① The origin and course of the medial femoral circumflex artery was observed.② The length of the artery trunk was measured.The distances between the origin(A) of the artery to the main anatomical marks [the peak of greater trochanter (B),the inward peak of lesser trochanter (C),and the crosspoint (D) of the femoral artery and the pubic edge or the acetabulum inlet edge] were measured.Comparisons of the measurements were conducted between genders.③ The distance between point A and point E,the starting point of the femoral profound artery,was measured.Comparisons of the measurements were conducted between genders.Results 2.9％ (3/103) of the subjects had their bilateral medial femoral circumflex arteries originate from the femoral artery,94.2％ (97/103) had their bilateral medial femoral circumflex arteries originate from the femoral profound artery,and 2.9％ (3/103) had one medial femoral circumflex artery originate from the femoral artery and the other from the femoral profound artery.1.9％ (4/206),76.7％ (158/206) and 21.3％ (44/206) of the subjects had the artery of screw type,of circuitous type and of straight type,respectively.The artery trunk goes posteriorly and medially after it is issued,divides into branches along the course,continues to go around the back of the femoral neck,and finally goes to the outward and upper direction.There were no statistical differences between males and females regarding length of the artery trunk,or distances between points AB,AC,AD or AE (P ＞ 0.05).Conclusion Since 3DCTA can clearly demonstrate the origin,course and anatomical morphology of the medial femoral circumflex artery,it can be used to provide anatomical aids for clinical evaluation and treatment of hip injury.

[Objective]The best treatment method for cemented acetabular component loosening during revision hip replacement has not been established.The purpose of this study is to determine the initial results obtained with a unique implant the modular porous tantalum cup,designed as an alternative treatment for aseptic prosthesis loosening following total hip arthroplasty.[Method]From Apr. 2006 to Nov.2006,porous tantalum cups were implanted during sixteen revision total hip replacements in nine women and seven men who had an average age of 69.2 years at the time of the procedure.Harris score and UCLA activity score were measured before,at 1,2 years and after arthroplasty.Radiographic follow-up was performed simultaneously.All patients were followed-up clinically and radiographically.[Result]The mean follow-up period was 24 month (range18-25months).The mean preoperative Harris hip score(HHS) was 21-54 (32.6) compared with the postoperative HHS of 56-90 (87.5).The mean preoperative UCLA score was 2-5(3.8) compared with the postoperative score of 6-9 (8.2).Radiographic evaluation of the revised components demonstrated no evidence of loosening or subsidence,and all showed radiographic evidence of bone ingrowth.[Conclusion]At the time of short-term follow-up,the porous tantalum cup effectively provided structural stability for acetabular component failure of cemented primary fixation.The potential for long-term biologic fixation may provide durability for porous tantalum cup.Long-term follow-up and comparison with alternative revision techniques will be required to evaluate the true effectiveness of this treatment approach.

Objective: To study the scavenging capacity of extract from four kinds of barley leaves on superoxide free radical and hydroxyl free radical. Methods: Measure the content of superoxide free radical and hydroxyl free radical by nitro blue tetrazolium(NBT) photo-reduction. Results: Along with the flavonoid in the reaction liquid, the scavenging rate shows ascending trend . When the concentration of flavonoid is 12?g/ml, its scavenging rate is 95.56% and 94.12% on superoxide free radical and hydroxyl free radical respectively. Conclusion: The flavonoids of barley leave s have stronger anti-oxidative action.

Objective To find out about the use of anti-infectious agents by tumor outpatients of the hospital. Methods A survey was conducted on 1 011 prescriptions for anti-infectious agents written out in the hospital from October to December of 2003 and an analysis was made of the structure and rationality of their use by means of drug utilization studies. Results The utilization rate of anti-infectious agents was 8.35% , accounting for 1.09% of the total sum of money for the prescriptions. The kinds of anti-infectious agents used were mostly cephalosporins and quinolones. The utilization rate of agents of compatibility was 4.44%. The drug utilization index of some chemicals was close to 1.00, accounting for about 44.44% . Conclusion There is no widespread abuse of anti-infectious agents by the outpatients of the hospital and the utilization rates of anti-infectious agents and agents of compatibility are low. Still, there are some problems in the use and compatibility of certain agents and the rationality of their use is to be questioned. The use of anti-infectious agents should be planned in a scientific way and in line with the economic condition of the patients.

The training of clinical skill is closely linked with medical personnel education.However,traditional paper-type training materials were unable to meet the training needs.As a new type of training materials,trial-and-error video-type clinical skill training materials (abbreviated as TEVT clinical skill training materials) have gradually attracted attention with its characteristics of lively and interesting,potentially informative,high acceptance among students,the advantages' of stimulating students' initiative exploration and consideration,fostering students' critical spirit and humanities.On the basis of analyzing the advantages' of TEVT training materials,we discussed the developing specialties of TEVT clinical skill training materials from four aspects as the material orientation and the application object,material sources,constructing the developing team and editing the teaching materials.Furthermore,we reflected the application prospect of TEVT clinical skill training materials in the future,in order to explore an available implementation path for the development of TEVT clinical skill training materials.

Objective Video-assisted thoracoscopic surgery is widely used in clinical practice,due to the characteristics of minimal invasion,quick recovery,low incidence of postoperative chest pain and the same effect of lobectomy as thoracotomy.However,the surgical itself has a certain degree of difficulty,and due to the effect of lymph node,intraoperative blood loss,pleural adhesions,conversion to thoracotomy surgery is needed in some cases. Understanding the risk factors of conversion to thoracotomy can help thoracic surgeons figure out the right time to operate the surgery.
