ABSTRACT
Objective: To evaluate the effectiveness of cemented polyethylene liner technique in hip revision. Methods: Based on inclusion criteria, the clinical data of 26 patients who were undergone hip revision between January 2011 and December 2013, were retrospectively reviewed. Among them, 14 cases were treated with isolated liner exchange (group A) and 12 cases were treated with cemented polyethylene liner technique (group B). There was no significant difference in gender, age, the time from primary total hip arthroplasty to revision, and the preoperative Harris score between 2 groups ( P>0.05). The post-operative Harris score and complications were compared between 2 groups, and X-ray findings of the hip joint were recorded to review the position of hip components. Results: All patients were followed up 4.4-6.4 years (mean, 5.4 years). Except for two femoral fractures during the revision (1 in each group), there was no other complication in 2 groups. The hip pain relieved and the lame gait corrected in 2 groups. The hip's function of 2 groups improved gradually after operation, with a better Harris score at 3 months and the best at the last follow-up, compared with preoperative scores ( P0.05). X-ray films showed no dislocation, aseptic loosening, and other interface related complication. Conclusion: For the cases without the chance to do change liner, cemented polyethylene liner technique has a good effectiveness. But restrict patient selection should be considered before hip revision.
ABSTRACT
Objective To analyze the relationship between cystatin C(Cys C) and homocysteine(Hcy) in patients with early diabetic nephropathy.Methods48 cases of T2DM patients from June 2013 to December 2015 in our hospital for treatment were chosen as the observation group, including 30 patients with early diabetic nephropathy patients as the observation group 1, 18 cases of T2DM patients as the observation group 2, were selected in our hospital physical examination of 28 healthy persons as control group,serum Cys C and Hcy levels were measured at the same time, urinary albumin / creatinine ratio (Ualb/cr) was measured in the observation group, test results of three groups were analyzed and compared.ResultsThe serum Cys C and Hcy in the observation group were significantly higher than the control group, and Cys C and Hcy levels in observed 1 group were significantly higher than that observed in the 2 group, the difference was statistically significant in the observation group, serum Cys C and Hcy level was positively correlated with Ualb/cr.ConclusionThe relationship between Cys C and Hcy levels and early diabetic nephropathy has very important significance in the early diagnosis of diabetic nephropathy, can effectively improve the rate of diagnosis of early diabetic nephropathy patients.
