Electrocardiogram (ECG) signals are susceptible to be disturbed by 50 Hz power line interference (PLI) in the process of acquisition and conversion. This paper, therefore, proposes a novel PLI removal algorithm based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD). Firstly, according to the morphological differences in ECG waveform characteristics, the noisy ECG signal was decomposed into the mutated component, the smooth component and the residual component by MCA. Secondly, intrinsic mode functions (IMF) of PLI was filtered. The noise suppression rate (NSR) and the signal distortion ratio (SDR) were used to evaluate the effect of de-noising algorithm. Finally, the ECG signals were re-constructed. Based on the experimental comparison, it was concluded that the proposed algorithm had better filtering functions than the improved Levkov algorithm, because it could not only effectively filter the PLI, but also have smaller SDR value.

Objective: To explore the application of extensive pterional approach combined with cutting of the zygomatic arch for the resection of large sphenoid ridge meningioma. Methods: Thirty-three patients with large sphenoid ridge meningioma underwent operation using the extensive pterional approach combined with cutting of the zygomatic arch. Twenty patients with large sphenoid ridge meningioma received operation with the traditional pterional approach as the control. The resection rate, operative time, intraoperative blood loss, and postoperative complications were compared between the groups. Results: Two groups of patients underwent craniotomy under microscope. The Simpon grade I resection and grade Ⅱ resection rate was 93.9% in the cutting of the zygomatic arch approach group and 60.0% in the control group (P<0.01). The operative time was (325.2±121.3) min in the cutting of the zygomatic arch approach group, which was significantly shorter than that in the control group with (406.4±182.9) min (P<0.05). The intraoperative blood loss was (502.5±101.8) mL and (697.7±115.4) mL in the two groups (P<0.05). In addition, postoperative complication rate was 15.2% and 45.0% in the cutting the zygomatic arch approach group and the control group, respectively (P<0.05). No death was reported in both groups. Conclusion: Extensive pterional approach combined with cutting of the zygomatic arch can fully expose the anatomical structures of the skull base and the sellar region to eliminate the influence of temporal muscle in the exposure of the surgical area. The operative field is exposed to reduce the stretch injury to only the frontotemporal brain tissue, which might be helpful for the complete resection of large sphenoid ridge meningioma, and is more conducive to neurovascular anatomy and relevant functional protection.

Objective To investigate the expression of human macrophage metalloelastase(HME) both in gastric cancer cell lines and gastric cancer tissues,and to find the role of HME in gastric carcino genesis.Methods Fifty eight patients who were operated in our hospital during April to Aug.2003 were enrolled.The samples taken from cancer,paracancer or normal tissues of these patients and cancer cell lines(MGC-803,SGC-7901,AGS)were detected for HME protein and HME mRNA expressions by Western blot and immunohistochemistry,RT-PCR and fluorescence quantitative PCR,respectively. Results Both HME mRNA and HME protein expressions were found in all three gastric cancer cell lines.The expressions of HME mRNA and HME protein in gastric cancer tissues was increased signifi- cantly compared with that in normal tissues(P0.05).Conclusions The increased HME expression in gastric cancer tissures compared with normal tissue indicate that HME may be a potential tumor marker for gastric cancer.
