AIM: To explore a specific diagnostic method for local recurrent rectal ***: Immunoscintigraphy with 99mTc-labeled anti-CEA monoclonal antibody (MoAb) CL-58 was performed for patients suspected of having a postoperative local recurrent rectal cancer and the findings were compared with the results of conventional imaging and ***: A total of 36 patients with a suspected local recurrent rectal cancer underwent immunoscintigraphy with 99mTc-conjugated CL58. Local recurrence of rectal cancer was identified in 31 patients and established in 30 during operation, endoscopy and pathological examination. No local recurrence was found in 5 patients without specific accumulation of 99mTc during the follow-up. Immunoscintigraphy had a positive rate of 86.11%, a specificity of 83.33%, and a sensitivity of 100%.CONCLUSION: Immunoscintigraphy has a highly specific and predictive value for detecting local recurrent rectal cancer, especially after abdominal perineal resection (APR).

CrMoN composite coatings were deposited on the surface of the stainless steel by magnetron sputtering, then were treated by low temperature ion sulfuration. FESEM equipped with EDX was adopted to analyze the morphologies and compositions of the surface, cross-section and worn scar of the sulfuration layer. The valence states of the film surface were detected by XPS. The nano-hardness and nano-modulus of the layer were measured by a nano tester. The results of the friction and wear show that the CrMoN/MoS2 composite coating is a kind of ideal solid lubrication layer and possess an excellent antifriction and wear-resistance.

Because of the widely-used nonlinear loads, the problems of harmonics and low power factor in power systems are becoming more and more serious. In view of the above problems, a shunt three-phase active power filter （SAPF） based on discrete sliding mode control to suppress the harmonics was designed and the power factor improved. First, built the mathematical model of SAPF. Then, controlled the switch through analyzing the harmonic current that was controlled signal using discrete sliding mode control. Through simulation using MATLAB, verified the validity of the algorithm. By the simulation waveforms, it can be found that after the load current containing a large number of harmonics passes the active power filter, the waveform of the power current approximately becomes a sine wave and the harmonics is significantly reduced. As a result, it plays a good role in purifying power systems. Moreover, from the waveforms of harmonic current and power current, it can be found that the algorithm has a faster tracking speed. The waveform can fect.

The microstructure, hydrogen storage thermodynamics and kinetics of La5Mg95-xNix (x=5, 10, 15) ternary alloys with different Ni contents were investigated. The evolutions of the microstructure and phase of experimental alloys were characterized by X-ray diffractometry and scanning electron microscopy. The hydrogen storage kinetics and thermodynamics, and P-C-I curves were tested using a Sievert apparatus. It is found that increasing Ni content remarkably improves hydrogen storage kinetics but reduces the hydrogen storage capacity of alloys. The highest hydrogen absorption/desorption rate is observed in the La5Mg80Ni15 alloy, with the lowest hydrogen desorption activation value being 57.7 kJ/mol. By means of P-C-I curves and the van’t Hoff equation, it is determined that the thermodynamic performance of the alloy is initially improved and then degraded with increasing Ni content. The La5Mg85Ni10 alloy has the best thermodynamics properties with a hydrogenation enthalpy of -72.1 kJ/mol and hydrogenation entropy of -123.2 J/(mol·K).
