To determine heat-shock protein (Hsp)90 expression is connected with cellular apoptotic response to heat stress and its mechanism, chicken (Gallus gallus) primary myocardial cells were treated with the Hsp90 promoter, aspirin, and its inhibitor, geldanamycin (GA), before heat stress. Cellular viability, heat-stressed apoptosis and reactive oxygen species level under different treatments were measured, and the expression of key proteins of the signaling pathway related to Hsp90 and their colocalization with Hsp90 were detected. The results showed that aspirin treatment increased the expression of protein kinase B (Akt), the signal transducer and activator of transcription (STAT)-3 and p-IKKα/β and the colocalization of Akt and STAT-3 with Hsp90 during heat stress, which was accompanied by improved viability and low apoptosis. GA significantly inhibited Akt expression and p-IKKα/β level, but not STAT-3 quantity, while the colocalization of Akt and STAT-3 with Hsp90 was weakened, followed by lower cell viability and higher apoptosis. Aspirin after GA treatment partially improved the stress response and apoptosis rate of tested cells caused by the recovery of Akt expression and colocalization, rather than the level of STAT-3 (including its co-localization with Hsp90) and p-IKKα/β. Therefore, Hsp90 expression has a positive effect on cellular capacity to resist heat-stressed injury and apoptosis. Moreover, inhibition of Hsp90 before stress partially attenuated its positive effects.

The systematic collation and mining of ethnic medicine literature is the key to the screening and textual research of classic prescriptions. This study focused on the textual research of such key issues as the source of prescriptions, the translation of minority languages into Chinese characters and their corresponding medical terms, the original plants of drugs, and the standard dosage. It is believed that the methods and experience of textual research of classic prescriptions in traditional Chinese medicine(TCM) can be utilized by the ethnic medicine. At the same time, the prominent problems unique to ethnic medicine cannot be neglected.(1)Attention should be paid to extraterritorial traditional medical literature in the textual research of the source of prescriptions. For instance, Indian medical literature is the source of many classic prescriptions in Tibetan medicine, Ibn Sina's Canon of Medicine the source of those in Uygur and Hui medicine, and ancient Indian Buddhist classics the source of those in Dai medicine.(2)The translation and comparison of medical terms in different language systems requires the cooperation of linguists, historians, and medical experts, the combination of historical research, historical linguistics and clinical research methods, and the use of cross-language comparison. In recent years, the related research achievements like multiple translated and annotated versions of classical literature in ethnic medicine and their respective terminology standards have been constantly emerging.(3)In textual research of the original plants of drugs, the following two points deserve attention: one is that the same drug is used in different ethnic medical systems, but there are differences in the understanding of drug properties and active parts; the other is that the original plants of the same drug vary in different ethnic medical systems.(4)The derivation of some classic prescriptions in ethnic medicine from foreign classics results in the difference among measurement systems. In addition, the detailed dosage fails to be covered in some ethnic literature, so the dosage standard should be determined depending on clinical practice and expert consensus.

Plague is a virulent infectious disease in China. In this study, '3S' technology was used to perform spatial autocorrelation analysis and spatial interpolation analysis for Spermophilus dauricus (S. Dauricus, a species of ground squirrel) captured in Manchuria City in 2015. The results were visually inspected. During the two-month (May to July) plague surveillance in 2015, 198 S. dauricus individuals were captured in the study area in Manchuria City (48 monitoring areas) by using a day-by-day catching method. Spatial autocorrelation was conducted using the ArcGIS software, and the following significantly different results were obtained: Moran's I=0.228472, Z-score=2.889126, and P<0.05. Thus, a spatial aggregation was observed. In 2015, the distribution of S. dauricus diminished from west to east and from north to south of Manchuria. Geo Detector software was used to analyze the habitat factors affecting the spatial distribution of S. dauricus. This highly clustered species mainly exists in suburban communities, construction sites, and areas surrounding factories. In future studies, plague surveillances should be performed in areas around Manchuria and Zhalainuoer.
