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.

Objective To study the clinical effect of nerve stimulator combined with low back piexus sciatic nerve block for the arthroscopic surgery anesthesia. Methods 86 patients who required the arthroscopic surgery from March 2010 to March 2013 in our hospital were randomly divided into observation group (43 cases) and control group (43 cases). The observation group accepted nerve stimulator combined with low back plexus sciatic nerve block under the arthroscopic surgery;the control group adopted waist hard joint anesthesia during the arthroscopic surgery. Data of hemodynamics, effects of anesthesia, anesthesias maintaining time, rehydration fluids and adverse effect in both groups were recorded and compared. Results The time for preparation and control of anesthesia operation (Tr), time for feeling completely block (T1), time for recovery (T2), time for completely blocking (T3), time for movement recovery (T4) in observation group were significantly shorter than that of the observation group (P<0.05); the first time of urination (Tu) after operation was significantly longer in control group than that in the observation group (P < 0.05); MAP in the control group were lower than that in the observation group 20 minutes after anesthesia (T20,P < 0.05); complications in the control group were more frequent than that in the observation group. Conclusion The clinical effect of nerve stimulator combined with low back plexus sciatic nerve block for the arthroscopic surgery anesthesia is more obvious , especially for patients with relatively long operating time.

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.
