Objective To investigate the clinical results of the primary total hip replacement (THR) and the secondary THR after failed internal fixation in the elderly patients with displaced femoral neck fracture so as to find the optimal treatment for displaced femoral neck fractures in the elderly patients. Methods From April 2001 to April 2007,16 patients (Study Group) treated with a secondary THR after failed internal fixation and 20 patients (Control Group) treated with a primary THR were enrolled in the study and followed up. There were seven males and nine females, at average age of 66. 5 years (50-85 years) and with mean follow-up period of 58. 25 months (24-96 months) in the Study Group. There were six males and 14 females, at average age of 68.1 years (51-83 years) and with mean follow-up period of 49.50 months (24-70 months) in the Control Group. All patients were active and lucid before they suffered fractures. Blood loss and operation duration in THR were compared. Hip function (Harris score) and health-related quality of life (HRQoL, KPS index score) were assessed during the follow-up after THR. Results Operative duration was (115.63 ±34.35) minutes in Study Group and (91.25 ±15.80) minutes in Control Group (P<0.05). Blood loss was (546.86 ±377.04) ml in Study Group and (320.00 ±155.94) ml in Control Group (P<0.05). At follow up, Harris score and KPS index score were (87. 25 ±7. 53) points and (95. 00 ±5. 16) points respectively in Study Group, and (90.20±5.46) points and (96.00 ±0.73) points respectively in Control Group (P>0.05). There were no infections or re-operations in two groups, but with one death in each group during the follow-up. Conclusions THR is the optimal treatment for displaced femoral neck fractures in the elderly patients.The secondary THR after failed internal fixation has higher risks in operation compared with the primary THR for a displaced femoral neck fracture in the elderly patient.

This study was purposed to establish a method for detecting miRNA expression by using fluorescent quantitative polymerase chain reaction (RQ-PCR), and to investigate the application value of this method in quantitative detection of miRNA. Total RNA was extracted from the peripheral blood or bone marrow of 82 patients with chronic lymphocytic leukemia (CLL) and 70 patients with acute leukemias (AL). Standard curves of U6 and miRNA were constructed from 10-fold serial dilutions of the cDNA, the quantitative detection was performed by using real-time quantitative PCR with SYBR Green by Roche Light Cycler. U6 RNA was used as the reference, the relative expression levels of miR-15a, miR-16-1, miR-29b, miR-181a and miR-181b in patients with CLL, while miR-128-1, miR-223, let-7b, miR-155 and miR-181a in patients with AL were analyzed by 2((-DeltaDeltaCT)) method. The relative parameters including specificity, linearity range, sensitivity and repeatability were evaluated. The results showed that the RQ-PCR assay could precisely detect the mature miRNA in as few as 10-50 ng of total RNA with the sensitivity of 0.05 ng RNA. Ct values of miRNA and U6 were all within 15 to 30. A good linear relationship (R(2) > 0.980) was obtained from the standard curves, also the efficiency of amplification was above 90%. Only a specific peak was shown on the melting curve diagram. The coefficients of variation (CV) of interrun and intrarun assay was < 4.8% and 6.3% respectively. It is concluded that the RQ-PCR is a sensitive and fast method for the detection of miRNA with its high-flux and low cost, this method will facilitate the research with detection of miRNA.

This study was purposed to investigate the mutational status of DNA methyltransferase (DNMT3a) gene and the clinical features of AML patients with DNMT3a mutations. Using PCR combined with directly sequencing, the somatic mutations of DNMT3a involving residue of amino acid 882 were detected in 77 AML patients. Furthermore, the clinical features of these patients were also studied. The results showed that the DNMT3a mutation were detected in 7 out of 59 patients with de novo AML (11.9%), which included 4 patients with DNMT3a R882C, 2 patients with DNMT3a R882H and 1 patient with DNMT3a Y874C. Morphology examination indicated that 2 patients were M(2), 1 patient was M(4) and 4 patients were M(5). Cytogenetic analysis revealed that karyotype in 5 out of 7 patients with DNMT3a mutation were normal. In total of 27 patients with normal karyotype 5 patients (22.7%) were found harboring DNMT3a mutation, while no DNMT3a mutation was found in 21 patients with abnormal karyotype. The mutation rate in patients with positive CEBPA was obviously higher than that in patients with negative CEBPA (p = 0.002). Immunophenotype analysis showed that 4 patients (4/7, 57.1%) with DNMT3a mutation expressed lymphoid antigens including CD4 or/and CD7. There were no statistical significance in age, gender, blast cells of bone marrow, white blood cell and platelet counts, hemoglobin level, ratio of CR, mutations of FLT3-ITD, NPM1 and c-kit between patients with DNMT3a mutation and patients with wild DNMT3a (p > 0.05). It is concluded that the DNMT3a mutations are more prevalent in AML patients with normal karyotype accompanying with positive NPM1 and/or CEBPA mutation, the role of DNMT3a mutation in AML prognosis needs to be further studied.
