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.

BACKGROUND: Metal on metal (MoM) hip prosthesis has been used for more than 30 years. With the increasing number of young patients who used it, the metal ions cumulative in the body may cause the biological effects, such as cell toxicity, genetic toxicity, carcinogenicity and metal allergy, etc, which have received attention and concern. OBJECTIVE: To describe what influences the production of metal ions, and how metal ions distribute in human tissue after MoM hip prosthesis implantation. In particular the change of the metal ions serum level and the MoM hip prosthesis biological effects of the pathological manifestations were investigated. This paper also focused on the factors influencing metal ions serum level and the mechanism of metal ions biological effects. RETRIEVAL STRATEGY: A computer-based search of Pubmed database was undertaken to identify the articles between January 2004 and November 2007, with the key items of "metals, total hip replacement" and language was limited to English. Meanwhile the China Journal Full-text Database was retrieved for the related articles published from January 2000 to November 2007, with the words of "joint replacement, metal ions" in Chinese. Totally 267 articles were screened out, and checked primarily. Inclusion criteria: ①prosthesis interface described the articles for MoM;②procedure described in the articles for hip replacement;③ articles focused on biological effects of metal ions. Exclusion criteria: ①non-MoM interface of the prosthesis;②non-hip arthroplasty;③articles described the metallurgy;④reproducibility study. LITERATURE EVALUATION: Both titles and abstracts were screened preliminarily, excluding 194 articles of unrelated objectives, 58 articles of repeated contents and 0 Meta analysis. Finally 30 articles were taken into further analysis, including 6 reviews and other basic or clinical trials. DATA SYNTHESIS: MoM prosthesis releases metal ions in the body through electrochemical process (corrosion) and enhanced machinery plus electrochemical process (wear-corrosion). It spreads to various body tissues by body fluid, and raises a number of biological effects. Human body shows a reaction of metal ions in a dose-dependent manner, and metal ions serum level decides the biological effects. Generally we consider the serum concentration of metal ions is influenced by ①ion excretion factors. ② mechanical factors. ③individual factors. ④others. At present, the biological effects of metal ions include ①inflammatory response, ②oxidative damage, ③apoptosis, ④osteoporosis and extracellular matrix dissolution, ⑤carcinogenesis, ⑥host response. Its mechanism is related with corrosion, macrophage activation, reactive oxygen generation, osteoblast function inhibition, osteoclast activation, metal-protein complex formation, and so on. The consequence is a series of pathological changes: ①foreign body granuloma synovitis, ②draining lymph node lesions, ③chromium calmly disease, ④malignant lesions, ⑤metal allergy. CONCLUSION: There is no better product to replace MoM hip prosthesis. Through the study of their biological effects, people gradually concern about two issues. First: What is a safe wear rate? Second: What is harmful serum level of metal ions?

[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 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.
