Objective To evaluate the role of hippocampal adenosine monophosphate-activated protein kinase (AMPK) signaling pathway in reduction of postoperative cognitive dysfunction by electroacupuncture (EA) preconditioning in aged rats.Methods A total of 150 healthy male Sprague-Dawley rats,aged 18-20 months,weighing 400-500 g,were randomly divided into 5 groups (n=30 each) using a random number table:control group (group C);splenectomy group (group O);preconditioning with EA at non-acupoint group (group NEA);preconditioning with EA at Baihui acupoint group (group EA);preconditioning with EA at Baihui acupoint + AMPK inhibitor group (group EAC).EA and EAC groups received EA at Baihui acupoints with a sparse-dense wave at an intensity of 1 mA and a frequency of 2 Hz/15 Hz for 30 nin,once a day,for 5 consecutive days,and splenectomy was performed at 24 h after the end of the last stimulation.Group NEA received EA at the points 2 mm lateral to the acupoints of Baihui,and the other treatments were similar to those previously described in group EA.Compound C 20 mg/kg was injected intraperitoneally at 5 min before operation in group EAC.Morris water maze test was performed at 1,3 and 5 days after operation,and the escape latency and swimming distance were recorded.The rats were then sacrificed,and brains were removed for examination of the pathological changes in the hippocampal CA3 region and for determination of the expression of AMPK,phosphorylated AMPK (p-AMPK),nuclear factor kappa B (NF-κB),interleukin-1beta (IL-1β),and tumor necrosis factor-alpha (TNF-α) by Western blot.Results Compared with group C,the escape latency and swimming distance were significantly prolonged,and the expression of AMPK,p-AMPK,NF-κB,IL-13,and TNF-α was significantly up-regulated in O,NEA,EA and EAC groups (P＜0.05).Compared with group O,the escape latency and swimming distance were significantly shortened,and the expression of AMPK,p-AMPK,NF-κB,IL-1β and TNF-α was significantly down-regulated in EA and EAC groups (P＜0.05),and no significant change was found in the parameters mentioned above in group NEA (P＞0.05).Compared with group EA,the escape latency and swimming distance were significantly prolonged,the expression of AMPK and p-AMPK was significantly down-regulated,and the expression of NF-κB,IL-1β and TNF-α was significantly up-regulated in group EAC (P＜0.05).Conclusion Activation of hippocampal AMPK signaling pathway is involved in EA preconditioning-induced improvement in postoperative cognitive dysfunction in aged rats.

Objective To investigate the effect of bortezomib with arsenic trioxide different concentration on the cell cycle and apoptosis of Raji cells. Methods Flow cytometry analysis showed that the relative number of cells in different phases and the percentages of cells calculated in G1 and S phase of the cell cycle and apoptosis were assessed after treatment with As2O3 and BOR or in combination with BOR in different concentration at indicated time (24 h, 48 h, 72 h). Results Flow cytometric analysis showed that the cell cycle was arrested at G1 phase, the number of cells G1 period increased significantly, and S phase decreased on Raji cells after As2O3 treatment. The relationship between the cellular DNA contents and the concentration of As2O3 showed a dose-and time-dependent manner (P ＜0.0001). But it was found that BOR had no effect on Raji cell cycle, but, in two drugs combination, cell apoptosis rate significantly increased from 16.98 % to 45.84 %. Conclusion The results show that As2O3 exerted variable and definite effects on lymphoma Raji cells, which indicated that As2O3 might induce apoptosis and arrest cell cycle. The combination of two drugs had a effective and synergistic effect on apoptosis.

OBJECTIVETo detect mutation in the rhodopsin gene (RHO) in a Chinese family with autosomal dominant retinitis pigmentosa (ADRP).

METHODSA total of 25 family members from a Chinese family were investigated. All the subjects were examined clinically by direct funduscopy, perimetry and vision test. Evaluation of the proband included electroretinography (ERG). Genomic DNA was extracted using standard method.

Objective: To forecast the risk distribution of inter-animal plague in Meriones unguiculatus effectively and provide scientific evidence for prevention and control of inter-animal plague, through studying the correlation between meteorological and environmental factors and inter-animal plague in Meriones unguiculatus. Methods: Positive data of plague bacterial culture in 30 epidemic source areas of Meriones unguiculatus in the Inner Mongolia plateau from 2005 to 2018, including detecting time, number of bacteria, latitude and longitude or detailed location, host type, were from the Chinese Disease Prevention and Control System Plague Prevention Management Information System and related professional institutions for plague prevention and treatment. Logistic regression was used to explore the relationship between the inter-animal plague and climate-related risk factors. The Maximum Entropy (Maxent) model was used to predict the habitat distributions of inter-animal plague, and the receiver operating characteristic (ROC) curve was used to validate the model. Results: There were 11 climatic factors including annual mean temperature, isothermality, temperature seasonality, mean temperature of driest quarter, mean temperature of warmest quarter, mean temperature of coldest quarter, annual precipitation, precipitation seasonality, globcover, normalized difference vegetation index and slope, were related to the outbreak of plague among Meriones unguiculatus and included in the model (OR = 1.302, 0.455, 0.957, 0.930, 4.864, 0.179, 0.986, 1.126, 0.992, 0.981, 0.721, P < 0.01). The increase of annual mean temperature, mean temperature of warmest quarter and precipitation seasonality will increase the risk of animal plague in the plague foci of Meriones unguiculatus; the increase of isothermality, temperature seasonality, mean temperature of driest quarter, mean temperature of coldest quarter, annual precipitation, globcover, normalized difference vegetation index, and slope will reduce the risk of animal plague in the plague foci of Meriones unguiculatus. The areas under the curve (AUCs) of the Maxent model training data and test data were 0.988 and 0.985, the prediction effect of the model was better. The habitat distribution of Meriones unguiculatus plague mainly concentrated in the central and northern Ulanqab plateau, Ordos plateau, and eastern Hetao plain. Conclusions The use of Maxent model and climate data can predict the potential risks and spatial distribution of animal plague in Meriones unguiculatus; the results are accurate and reliable.
