Free flap monitoring with continuous tissue oxygen tension measurement

Intraoperative and postoperative free flap monitoring by means of oxygen tension measurement was carried out in 11 patients. We used an invasive flexible microcatheter that allowed for measurement of oxygen tension in all types of free flaps. Two cases of the measured flaps were buried free flaps which do not allow monitoring by clinical assessment. All flaps monitored in this study survived. One case of displacement of the microcatheter occurred. In one patient, the tissue pO₂ monitor successfully detected early vascular thrombosis with subsequent reoperation and salvage of the free flap.     

磺柳酸法在Array360全自动特定蛋白分析仪尿液测定中的应用

目的探讨磺柳酸法在Array360全自动特定蛋白分析仪尿液测定中的应用价值。方法用磺柳酸法对离心后的尿液样本中的蛋白质进行半定量测定,并用Array360全自动特定蛋白分析仪测定α1微球蛋白α1-MG、白蛋白(ALB)、转铁蛋白(TRF)、免疫球蛋白G(IgG)在各个稀释度的测定范围,结合尿液蛋白质半定量结果和各个项目在不同稀释度的测定范围设定初始的标本稀释度。结果蛋白质半定量结果不同的尿液标本用Ar-ray360进行测定时,各个项目有其合适的初始标本稀释度。结论磺柳酸法在Array360全自动特定蛋白分析仪尿液的测定中有重要的应用价值,可大幅度节约试剂成本,缩短测定时间。     

初次吸毒者与复吸者戒毒期间生活质量比较

目的:了解包头市初次吸毒者与复吸者戒毒期间的生活质量。方法:用QOL-DA2.0量表对戒毒人员的生活质量进行调查。结果:初次吸毒者与复吸者各纬度进行t检验显示躯体功能纬度(t=10.51)、心理功能纬度(t=5.94)、症状及毒副作用纬度(t=6.41)、社会功能纬度(t=10.47)和总分(t=10.48)均有统计学意义(P<0.001),表明戒毒期间初次吸毒者的生活质量高于复吸者。结论:在戒毒期间初次吸毒者的生活质量较复吸者易改善。     

老年高血压患者脉压与急性心肌梗塞的关系

目的探讨老年原发性高血压（ET）患者脉压与急性心肌梗塞（AMI）的关系。方法观测45例老年高血压病合并急性心肌梗塞患者的收缩压（SBP）、舒张压（DBP）及脉压（PP），以31例老年单纯高血压患者（冠脉造影排除冠心病）作对照组，进行比较。结果并发急性心肌梗塞组，其脉压较单纯高血压组明显增高。结论脉压与老年人急性心肌梗塞密切相关，对老年人高血压的治疗更要注重控制脉压。     

Pedicled deltoid hatchet flap for treatment of pressure sore at the shoulder

Whereas decubitus ulcer in the back or hip region is a common entity in plegic or elderly patients, the occurrence in the lateral shoulder region is seldom seen. However, resulting from continuous lateral decubitus positioning or limited compliance by the patient, pressure sores may occur in almost any region of the body, but predominately, they arise in acral zones with underlying bone prominences. The deltoid area is such an anatomically critical region, especially if the underlying deltoid muscle is paralyzed. The transposition of a pedicled deltoid flap, slightly modified as a hatchet flap, is described for cover of a decubitus ulcer in the deltoid region in a paraplegic male. Although utilization of the deltoid flap as a free flap is an established procedure for selected indications [Russell et al. (1985) Extremity reconstruction using the free deltoid flap. Plast Reconstr Surg 76:586–595, Serafin D (1996) The deltoid flap. In: Serafin D (ed) Atlas of microsurgical composite tissue transplantation, chapter 19. Saunders, Philadelphia, PA, pp 153–159, Wang et al. (2003) The free deltoid flap: microscopic anatomy studies and clinical application to oral cavity reconstruction. Plast Reconstr Surg 112:404–411], transposition as a pedicled flap, to the best of our knowledge, has not been previously described in the available literature.     

小型移动数字成像系统下行经皮冠状动脉腔内成形术

A new pedicled seromuscular flap technique for high-risk intestinal anastomoses

A new method for protecting intestinal anastomoses in patients at high risk of anastomotic dehiscence or fistula formation is described herein. This method involves raising a seromuscular flap on a pedicle from the stump of the intestine to be anastomosed. The anastomosis is performed, then covered with the seromuscular flap.

Anatomic bases of tongue flaps

Summary The morphological structure of the lingual a. was studied in 50 dissected and 14 vascular cast specimens. The course of this artery is divided into 4 segments: the original segment, the segment within hyoglossus, the ascending and the horizontal segments of the deep lingual a. The root of the tongue is supplied by 2 to 3 root branches of the lingual a., the ascending palatine a. and the tonsillar a. The body of the tongue is nourished on average by 25 arterial branches from the deep lingual a. The ventral surface of the tongue, as well as the sublingual gland and the floor of the mouth, is supplied by the sublingual a. The termination of the lingual a. anastomoses with the submental branch of the facial a. to form the lingual frenal a. Except for a submucous arterial network on the dorsum of the tongue, all blood vessels are separated completely by the lingual septum, through which arterial anastomoses (2.0 mm in diameter) can be found occasionally.This work was supported by the National Natural Science Fund
