Objective To explore the application status of protease spectrum analysis in breast cancer. Methods The pertinent literatures in recent ten years were screened with key words “breast cancer，diagnosis，and protease spectrum”. Results At present，the candidate markers being identified in enzyme platform were less， such as ITIH4， C3adesArg，C3adesArg△8， haptoglobin-α1，S100-A9， and so on. In addition to S100-A9，the results of markers in the different research institutes were often contradictory. There had been no large-scale applications in clinical research and more further researchs were needed to prove it’s value. Conclusions Breast cancer tissue or cells obviously express chemokines and their receptors which participate the growth， invasion， and metastasis of breast cancer，and many factors influence the activation of their signals. With the development of proteomics research progress of technology and equipment， the improvement of method and more research data， protease spectrum plays an important role in improving the early diagnosis rate of breast cancer.
Objective To investigate the cl inical effect of minimally invasive internal fixation percutaneous plate osteosynthesis (MIPPO) assisted by arthroscopy on tibial plateau fractures. Methods From September 2005 to December 2007, 29 patients with tibial plateau fracture underwent arthroscopy-assisted MIPPO, including 18 males and 11 females aged18-59 years old (average 34.7 years old). There were 8 cases of type II, 10 of type III, 5 of type IV, 3 of type V, and 3 of type VI according to Schatzker classification system. The fracture was combined with meniscus injury in 13 cases, anterior cruciate l igament injury in 4 cases, and medial collateral l igament injury in 3 cases. The time from injury to operation was 2-10 days. Firstly, the combined injury was treated under arthroscopy. Then, reduction of tibial plateau fractures was performed, bone grafting was conducted in the area of bone defect, and internal fixation using strut plates was performed after establ ishing subcutaneous tunnel via minimally invasion. Early rehabil itation activities were carried out for each patient 1 day after operation. Results No early compl ications such as poor heal ing of incisions, infections, and osteofascial compartment syndrome occurred. Over the follow-up period of 12-39 months (average 24 months), there was no failure of internal fixation, traumatic knee osteoarthritis, and inversion and eversion of the knee. The fractures healed within 3-4.5 months (average 3.5 months). The cl inical effect was excellent in 23 cases, good in 4 cases, and fair in 2 cases according to Lysholm knee rating system, and the excellent and good rate was 93.1%. Conclusion Arthroscopy-assisted MIPPO is a safe and effective way of managing tibial plateau fractures due to its features of minimal invasion, earl ier recovery, fewer compl ications, and simultaneous treatment of associated intra-articular injuries.
目的:评价免疫印迹法检测胰岛自身抗体（GAD-A、ICA、IAA）与酶联免疫法测ICA、GAD-A放射免疫法测IAA结果的一致性。方法:采用免疫印迹法测定81例糖尿病患者胰岛自身抗体,将结果与酶联免疫法测定的GAD-A、ICA,放射免疫法测定IAA结果进行比较。结果:免疫印迹法阳性检出率为:GAD-A 51.8%,ICA 18.5%,IAA 27.1%；酶联免疫法（GAD-A、ICA）、放射免疫法（IAA）阳性检出率:GAD-A 32.1%,ICA 34.5%,IAA 30.8%；上述两组结果进行比较,两组相比ICA和GAD-A有统计学差异（Plt;0.05）,IAA无统计学差异。两组结果一致率比较:GAD-A 50.6%,ICA 64.2%,IAA 69.1%。结论:与临床常用酶联免疫法检测GAD-A、ICA,放射免疫法检测IAA比较,免疫印迹法和酶联免疫法在ICA及GAD-A阳性检出率上的差异有显著性,和放射免疫法在IAA阳性检出率上差异无显著性。
目的 探讨十二指肠损伤的诊断、手术治疗及手术方式的选择。方法 对我院2000年3月至2007年5月收治的16例十二指肠损伤患者的临床资料进行回顾性分析。结果 16例均进行手术治疗，仅3例术前明确诊断，术中确诊13例； 术后并发症4例； 16例均治愈出院。结论 十二指肠损伤的病情复杂，治疗成败的关键是掌握好早期手术探查指征和选择合适的术式。对于较重的Ⅲ、Ⅳ级十二指肠损伤者，改良十二指肠憩室化手术为一种较理想的手术方法。
ObjectiveTo investigate the effectiveness of posterior minimally invasive approach for internal fixation of displaced scapula fractures. MethodsBetween January 2006 and December 2011,16 patients with scapular fractures underwent surgical fixation by a minimally invasive approach,including 11 cases of displaced glenoid fractures and 5 cases of unstable scapular neck/body fractures.There were 12 males and 4 females,aged 35-69 years (mean,53 years).The causes of injury were traffic accident in 10 cases,falling from height in 4 cases,and tumble in 2 cases.In 11 cases of displaced glenoid fractures,6 were rated as Ideberg type Ⅱ,2 as Ideberg type Ⅲ,1 as Ideberg type IV,and 2 as Ideberg type V,with a fracture displacement of more than 3 mm.In 5 cases of unstable scapular neck/body fractures,there were 3 cases of scapular neck fractures and 2 cases of scapular body fractures,with a fracture end angulation of more than 20°;3 cases had floating shoulder injury.The interval of injury and operation was 4-14 days (mean,6 days). ResultsThe mean operation time was 105.8 minutes;the mean intraoperative blood loss was 105.8 mL,and the mean hospitalization time was 17.6 days.Three patients had inflammation around the surgical incision,which was controlled by change dressing;primary healing of incision was obtained in the others.The patients were followed up 12-36 months (mean,24 months);all fractures healed within 12-19 weeks (mean,15.8 weeks).There was no implant failure or deep infection.Constant shoulder score,disability of the arm,shoulder,and hand (DASH) score,and visual analogue scale (VAS) score at post-operation had a significant improvement when compared with scores at pre-operation (P<0.05),but no significant difference was found between different time points at post-operation (P>0.05).Shoulder joint activities were gradually restored during the follow-up;the shoulder range of motion in elevation,abduction,internal rotation,and external rotation at 12 months after operation and last follow-up were significantly higher than those at 6 months after operation (P<0.05),but difference was not significant between at 12 months and last follow-up (P>0.05). ConclusionPosterior minimally invasive approach for internal fixation has good effectiveness in treating displaced scapula fractures,with the advantages of no need for a large subcutaneous flap and an extensive Judet incision or creation of muscular flaps.
Objective To summarize the application and progress of common autologous organ transplantation (AOT) techniques. Method A literature review and summary of previous and recent studies on common AOT was performed, including autologous liver transplantation, autologous kidney transplantation and intestinal autotransplantation techniques. Results AOT solved the issues of bleeding that cannot be controlled by in vivo resection of lesions, difficulties in vascular reconstruction, and the inability to radically resect lesions, and extended the indications for treatment of partially diseased conditions. Conclusions The AOT technique has an ameliorating effect on the tight donor situation in China, providing more potential donors. And the application of the AOT technique effectively avoids the usage of postoperative immunosuppressive drugs and the progression of lesions due to waiting for allogeneic organ transplantation. However, the clinical benefit in malignant tumors remains to be further investigated.
