The farming-pastoral ecotone has an important strategic place in the energy supply and ecological layout of China. Thus, exploring the spatial and temporal variation characteristics of carbon emissions in this region will help to deeply understand the information on the historical carbon emissions in China's energy production bases and provide data references for the formulation of differentiated emission reduction policies and the promotion of regional energy-saving and carbon-reducing measures, which is of great significance for the realization of low-carbon economic development. This study constructed a spatialization model of carbon emissions based on land use, night lighting, and provincial energy consumption data; explored the spatiotemporal changes and aggregation characteristics of carbon emissions in the farming-pastoral ecotone from 1995 to 2020 using the global Moran's index and hotspot analysis; and then combined it with the slack-based measure model to calculate the carbon emission efficiency and emission reduction potential of each city from 2010 to 2020 and classify cities to propose a differentiated emission reduction path.

Objectives: To observe the effect of simulated repeated transcranial acupuncture (rTAS) on learning and memory abilities and cerebral microvascular flow in vascular dementia (VD) model rats, so as to explore the potential mechanism of rTAS in treating VD.

Methods: Thirty-two Wistar rats were randomly divided into normal, model, acupuncture and rTAS groups (=8 rats in each group). The VD model was established by permanent ligation of bilateral common carotid arteries.

Conventional imaging methods such as magnetic resonance imaging, computed tomography and digital subtraction angiography have limited temporospatial resolutions and shortcomings like invasive angiography, potential allergy to contrast agents, and image deformation, that restrict their application in high-resolution visualization of the structure of microvessels. In this study, through comparing synchrotron radiation (SR) absorption-contrast imaging to absorption phase-contrast imaging, it was found that SR-based phase-contrast imaging could provide more detailed ultra-high-pixel images of microvascular networks than absorption phase-contrast imaging. Simultaneously, SR-based phase-contrast imaging was used to perform high-quality, multi-dimensional and multi-scale imaging of rat brain angioarchitecture.

The newt has the powerful capacity to regenerate lost limbs following amputation, and represents an excellent model organism to study regenerative processes. However, the molecular basis of the adaptive response in the regenerating limb of the Chinese fire-bellied newt Cynops orientalis immediately after amputation remains unclear. To better understand the adaptive response immediately after limb amputation at the protein level, we used isobaric tags for relative and absolute quantitation (iTRAQ) coupled with LC-MS/MS methods to analyze changes in the proteome of the regenerating newt limb that occurred 2 h and 8 h after amputation.

Primary squamous cell carcinoma of the breast (PSCCB) is a rare type of breast carcinoma, the clinical behavior of which has not been accurately characterized. The aim of this study was to evaluate its prevalence, characteristics, prognosis, and effective treatment modalities in patients attending our institution. The records of the Cancer Institute and Hospital of Tianjin Medical University from 1985 to 2013 were searched and 29 patients with PSCCB (0.

Objective: To investigate the expression of indoleamine 2, 3-dioxygenase (IDO) in breast cancer and its correlation with clinicopathologic factors and prognosis.

Methods: The expression of IDO, CD31, CD105 proteins in 40 specimens of breast cancer were assessed by immunohistochemistry.

Results: The overexpression rate of IDO in breast cancer was 67.

Objective: To analyze the clinicopathologic characteristics and the prognostic factors of breast cancer patients with skip metastases in the axilla.

Methods: The clinical data of 1502 breast cancer patients who underwent complete axillary lymph node dissection were retrospectively reviewed. The patterns of skip metastases, clinical features and prognostic factors were analyzed.
