Comprehending the spatial-temporal characteristics, contributions, and evolution of driving factors in agricultural non-CO greenhouse gas (GHG) emissions at a macro level is pivotal in pursuing temperature control objectives and achieving China's strategic goals related to carbon peak and carbon neutrality. This study employs the Intergovernmental Panel on Climate Change (IPCC) carbon emissions coefficient method to comprehensively evaluate agricultural non-CO GHG emissions at the provincial level. Subsequently, the contributions and spatial-temporal evolution of six driving factors derived from the Kaya identity were quantitatively explored using the Logarithmic Mean Divisia Index (LMDI) and Geographical and Temporal Weighted Regression (GTWR) methods.

Non-coding RNA is a kind of RNA that exists widely and cannot be translated into proteins, which has played a key role in the regulation of biological functions of tumor cells. However, the regulation mechanism of non-coding RNA on bladder tumors is not fully understood.

Methods: We investigate the relationships between electrolyte fluctuation and outcomes in survivors of acute myocardial infarction ( = 4386). Ion variability was calculated as the coefficient of variation, standard deviation, variability independent of the mean (VIM) and range.
Background: As an inorganic compound used to treat various cancers and other diseases, arsenic trioxide (AsO) has been reported to induce cellular apoptosis in certain kinds of cancers including bladder cancer. The aim of the present study was to elucidate the crucial cooperative role of AsO and intravesical bacillus Calmette-Guerin (BCG) immunotherapy and its ability to protect against bladder cancer by targeting the IER3/Nrf2 pathway.
Method: Initially, an orthotopic bladder cancer model was established in mice by means of intravesical instillation of the human bladder cancer cell line 5637.
Objective: To provide a scientific evidence for the identification of the section Cruciata Gaudin.
Methods: Seed morphology of the section Cruciata Gaudin in different regions from Gansu were studied by means of scanning electronic microscopy (SEM).
Results: The seeds of section Cruciata Gaudin had relative conformability in terms of shape,size and ornamentation.

An acid-assisted microwave digestion procedure is optimized for the determination of trace elements in traditional Chinese medicine by the use of flame atomic absorption spectrometric (FAAS) techniques. Microwave-assisted digestion has the advantages of reduced time for sample dissolution, fewer possibilities for technical errors caused by spilling of hot digestion solutions, use of less chemicals, and lower losses of volatile metals. In addition, modern microwave ovens are safer and simpler and provide more controlled and reproducible conditions than hot plate or block digesters.

Objective: To provide scientific basis for large scale production by studying the technique of tissue culture of Gentiana stramines.
Method: Callus was induced from germ-free stem segment of G. stramines on a MS medium supplemented with different hormones.
Objective: To amplify the PCR with the internal transcribed spacerl regions measure the base sequence of the amplified products of DNA, and to set up an identified standard on the level of molecule.
Method: DNA from the seeds of G. dahurica was extracted by conventional method, and composed peculiar primer was used to amplify with the internal transcribed spacerl regions of the rRNA gene, and the base sequence of the amplified products by stopping the circle of the end of double deoxidation of four color fluorescent mark was measured.
