1.The relationship of convulsion related brain damage and cell autophagy
International Journal of Pediatrics 2013;40(5):485-488
Autophagy is a lysosomal degradation of intracellular material composition,and plays an important role in nerve cell survival and clear senescent cells and misfolded proteins.Autophagy can protect nerve cells,but also can be used as one of the ways about nerve death.Repeated seizures can cause brain damage,but the specific mechanism is not clear.Recent studies have shown that,convulsion can activate apoptosis pathway and start autophagy,which can mediate the adaptation,injury or apoptosis of neurons.Convulsion brain injury is closely related to cell autophagy.Autophagy as a new important signaling pathway can provide a new therapeutic direction of convulsion brain damage.

Chinese Journal of Medical Imaging 2014;(9):681-685
Purpose CT spectroscopy imaging was used in the preoperative differentiation evaluation of renal clear cell carcinoma, to access its malignant degree preoperatively, and to guide the operation treatment. Materials and Methods The spectral characteristics of 40 patients with renal clear cell carcinoma (RCCC) were analyzed retrospectively, all the RCCC patients underwent gemstone spectral imaging (GSI) scans, to obtain spectral serial images for the arterial phase and medulla phase. Spectral characteristic parameters and spectrum curve between different grades of renal cell carcinoma was compared, and the results were compared with pathology. Results Among the 40 cases of patients, carcinoma of grade I, II and III were 13 cases, 15 cases and 12 cases respectively. CT value ratio of renal clear cell carcinoma of grade I, II and III under 70 keV were 1.17±0.25, 0.84±0.85 and 0.64±0.19 (F=23.697, P<0.05) in arterial phase and 0.83±0.12, 0.64±0.07 and 0.54±0.08 (F=30.975, P<0.05) in medulla phase;iodine concentration ratio was 1.19±0.40, 0.60±0.10 and 0.25±0.94 (F=32.932, P<0.05) in arterial phase, and 0.69±0.18, 0.43±0.94 and 0.26±0.51 (F=28.673, P<0.05) in medulla phase. Spectrum curve slope of renal clear cell carcinoma of grade I, II, III in arterial phase was 4.00±1.24, 2.16±0.95 and 0.92±0.64 (F=23.392, P<0.05), and 3.54±1.20, 2.70±0.71 and 1.20±0.44 (F=24.272, P<0.05) in medulla phase. Differences of water concentration in arterial and medulla phase between renal clear cell carcinoma with different grade were not statistically signiifcant (P>0.05). Conclusion The differences of CT value, energy spectrum curve slope, iodine value under CT spectroscopy single energy imaging between renal clear cell carcinoma with different nuclear grade were statistically signiifcant, which can be expected to provide the basis for preoperative therapy selection.
