BACKGROUND:As the latest generation of ultrahigh molecular weight polyethylene, vitamin E-stabilized ultrahigh molecular weight polyethylene has been widely put into use of various kinds of joint replacement. However, wear debris and osteolysis caused by that are stil the vital factor influencing the clinical curative effect. OBJECTIVE:To discuss and summarize the material characteristics and application progress of vitamin E-stabilized ultrahigh molecular weight polyethylene, and to seek the theoretical basis which can guide us to launch vitamin E-stabilized ultrahigh molecular weight polyethylene clinical y. METHODS:The first author retrieved the CNKI and Medline databases by computer. The keywords were“ultra-high molecular weight polyethylene, vitamin E-stabilized, joint replacement, application”in English. RESULTS AND CONCLUSION:Total y 92 articles were retrieved. According to the inclusion and exclusion criteria, 46 articles were included in result analysis. The results show that vitamin E-stabilized ultrahigh molecular weight polyethylene can not only enhance the physicochemical property of prosthesis, but also can integrate with free radicals to increase antioxidant rate of prothesis in order to prolong the long-term curative effect of prosthesis. However, it is stil lack of vast of clinical cases and fol ow-up as evidence. In case of that, long-term clinical efficacy remains to be assessed.

AIM: To observe the functional recovery of knee joint in patients with posterior cruciate ligament (PCL) under knee arthroscopy with ligament advanced reinforcement system (LARS) artificial ligament transplantation. METHODS: From January 2005 to May 2006, six patients with PCL injury treated by reconstruction of PCL with LARS artificial ligament transplantation were selected from the Department of Orthopedics, Huadu Hospital Affiliated to Southern Medical University. All subjects agreed with the operation before the surgery and all reconstruction surgeries were of second period. ① The tibial tunnel was established firstly. ② Then was the femoral tunnel. ③ Under knee arthroscopy, the "Y"-shape double cords of LARS artificial ligament were cut through ante-out and meta-in bone tunnels of femur, and fixed at 90o and 30o flexion respectively. Patients were required to motor 3 days postoperative, and patients actively exercised their quadriceps muscle of thigh at one week later. Regular follow-ups were conducted postoperatively, and functional evaluation of the knee joints was performed by according to Lysholm standards, including 8 aspects: Limping, supporting, interlocking, unstable, painful, swell, upstairs and downstairs and squatting with a total score of 100 points. The higher the score was, the better the functional recovery of knee joint. RESULTS: All of the 6 patients were available at follow-up, and no one withdrew from the study. The follow-up was conducted at the 7th, 7th, 10th, 10.4th, 12.8th, and 14th months with an average duration of 10.2 months. After operation, unstable symptoms of knee joint in all subjects disappeared with negative sag sign and posterior drawer. The Lysholm knee scores of patients postoperation were significantly higher than those before the surgery (83.5?4.5, 51.6?3.6, P

ObjectiveTo observe the effect of Orem self-care theory on the patients after renal transplantation.Methods102 patients after renal transplantation into were randomly divided into the observation group(52 cases),which received Orem self-care,and comparison group(50 cases),which received general care.Self-care ability,rate of infection and mental status of the 2 groups patients were observed and recorded.ResultsFor patients of the observation group,self-care ability of was obviously better(P<0.01),the rate of infection was lower(P<0.05),and mental status was improved(P<0.01) compared with patients of the observation group.ConclusionThe application of Orem self-care on patients after renal transplantation can promote self-care ability and decrease post-operation complications.

Objective To investigate the value of left ventricular function in patients with chronic pulmonary heart disease(CPHD) using strain rate imaging (SRI).Methods This study included 64 patients with CPHD (30 patients with compensatory function and 34 with decompensatory function) and 30 normal control.Peak systolic strain rate (SRs),peak early diastolic strain rate (SRe) and peak late diastolic strain rate (SRa)of left ventricular basal and middle segments were measured,and then mean peak strain rate (mSR) was calculated.The above digital parameters were analyzed compared with the conventional echocardiographic indices.Results The indices (mSRs,mSRe,mSRe/mSRa)in CPHD were reduced and mSRa increased as compared with those in controls (all P=0.000).And the above indices showed the same change when decompensatory group was compared with compensatory group (P=0.000,0.038,0.015,0.001).Negative correlation was noted between LVEF and mSRs in patients with CPHD (r=0.75,0.82;P=0.000).Conclusions LVEF is negatively related with mSRs in CPHD patients.mSRs can reflect the status of left ventricular function.SRI is a more sensitive tool in quantitative evaluation of left function of CPHD.

Idiopathic macular hole is a full - thickness defect of retinal tissue involving the anatomic fovea and affecting central visual acuity and quality of life in elder patients. Recent evidence showed that the alterations of choroidal blood flow and choroidal thickness are associated with the formation of macular holes. Enhanced depth imaging spectral-domain optical coherence tomography (EDI SD-OCT) enables in vivo measurement of choroidal thickness and may provide new insight into the understanding of pathogenesis of idiopathic macular hole. In this article, we reviewed current studies on the relationship between choroidal thickness measured by optical coherence tomography and the pathogenesis of idiopathic macular hole.
