Hygroscopicity research has long been a key focus and hot topic in Chinese materia medica(CMM). Elucidating hygroscopic mechanisms plays a vital role in formulation design, process optimization, and storage condition selection. Hygroscopic models serve as essential tools for characterizing CMM hygroscopic mechanisms, with various types available. The double exponential model is a kinetic mathematical model constructed based on the law of conservation of energy and Fick's first law of diffusion, tailored to the physical properties of CMM extracts. In recent years, this model has been extensively applied to simulate the dynamic moisture absorption behavior of CMM extracts and solid dosage forms under varying humidity conditions. It has revealed the correlation between moisture absorption kinetic parameters and material properties, offering a new perspective for characterizing the moisture uptake behavior of CMM. This paper systematically reviews the application progress of this model in the field of CMM, analyzes its advantages, disadvantages, and challenges in this domain, and explores its potential application trends in other fields. It aims to provide references for elucidating the moisture absorption mechanisms of CMM and researching moisture-proofing technologies, while also offering insights for its broader application in food and polymer materials.

OBJECTIVE To investigate the effect and mechanism of bumetanide on lung injury in chronic obstructive pulmonary disease (COPD) model rats. METHODS COPD rat model was induced by lipopolysaccharide, and they were randomly divided into model group (COPD group), bumetanide low-dose and high-dose groups (Bumetanide-L group, Bumetanide-H group), bumetanide high-dose+Yes-associated protein/transcriptional coactivator containing PDZ-binding motif (YAP/TAZ) signaling pathway activator group (Bumetanide-H+PY-60 group), with 12 rats in each group. Another 12 normal rats were selected as normal control group (Control group). Thirty minutes before modeling, bumetanide/normal saline was inhaled or/and PY-60/ normal saline was injected into the tail vein. On the next day after the completion of modeling and drug administration, the pulmonary function index of the rats in each group was measured [forced expiratory volume in 0.3 seconds (FEV0.3), forced vital capacity (FVC), peak expiratory flow (PEF), FEV0.3/FVC]. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-1β in bronchoalveolar lavage fluid (BALF) were determined; the pathological morphology of lung tissue and degree of pulmonary fibrosis were observed. The expression levels of transforming growth factor- β (TGF- β), α -smooth muscle actin (α-SMA) and TAZ protein as well as the phosphorylation of YAP protein in lung tissues were detected. RESULTS Compared with COPD group, the pathological injury of lung tissue in Bumetanide-L and Bumetanide-H groups was alleviated; the exfoliation of lung epithelial cells, tube wall thickening and the degree of pulmonary fibrosis were alleviated; inflammatory cell infiltration was reduced, and blue collagen deposition was reduced; FEV0.3, FVC, FEV0.3/FVC and PEF were significantly increased, while the lung injury score, levels of TNF-α, IL-6, IL-1β, expression levels of TGF-β, α-SMA and TAZ protein and the phosphorylation of YAP protein were significantly decreased (P<0.05). PY-60 could significantly reverse the improvement effects of bumetanide on above indexes (P<0.05). CONCLUSIONS Bumetanide can alleviate lung injury, inflammatory response and pulmonary fibrosis in COPD rats, and its mechanism is related to inhibiting YAP/TAZ signaling pathway.

Objective:
Previous studies have discovered a correlation between cigarette smoking and cortical thickness and surface area, but the causal relationship remains unclear. The objective of this investigation is to scrutinize the causal association between them.
Methods:
To derive summary statistics from a genome-wide association study (GWAS) on cortical thickness, surface area, and four smoking behaviors: 1) age of initiation of regular smoking (AgeSmk); 2) smoking initiation (SmkInit); 3) smoking cessation (SmkCes); 4) cigarettes per day (CigDay). Linkage disequilibrium score regression (LDSC) was employed to examine genetic association analysis. Furthermore, for traits with significant genetic associations, Mendelian randomization (MR) analyses were conducted.
Results:
The LDSC analysis revealed nominal genetic correlations between AgeSmk and right precentral surface area, left caudal anterior cingulate surface area, left cuneus surface area, left inferior parietal surface area, and right caudal anterior cingulate thickness, as well as between CigDay and left caudal middle frontal surface area, between SmkCes and left entorhinal thickness, and between SmkInit and left rostral anterior cingulate surface area, right rostral anterior cingulate thickness, and right superior frontal thickness (rg=-0.36–0.29, p<0.05). MR analysis showed a unidirectional causal association between left caudal middle frontal surface area and CigDay (βIVW=0.056, pBonferroni=2×10-4).
Conclusion
Left caudal middle frontal surface area has the potential to serve as a significant predictor of smoking behavior.

Based on the etiology and clinical diagnostic criteria of type 2 diabetes mellitus (T2DM), identification and typing of treatment from the perspective of traditional Chinese and western medicine, the criteria for evaluating the clinical compatibility of traditional Chinese and western medicine in animal models of T2DM were set up. The literature was reviewed to sort out and analyze the existing commonly used modeling methods, summarize the mechanism, compare the advantages and disadvantages, and calculate the consistency between the animal model and the clinical symptoms, syndromes, and indicators from the perspective of traditional Chinese and western medicine. The authors found that spontaneous animal models and high-fat diets combined with multiple low-dose streptozotocin (STZ) induction models were more in line with modern medical pathogenesis of T2DM. However, it fails to form some special syndromes required for traditional Chinese medicine (TCM) research. In addition, there are many methods of combining the etiology and pathogenesis of TCM, which can be divided into three categories: intervention carried out by drug administration, behavioral stimulation, or environmental changes according to TCM, or use of hormones according to clinical evidence and combination of the two methods mentioned above. All of them can successfully establish different types of animal models. However, different methods of establishing syndrome models have their own advantages and disadvantages, and there is no unified standard for the stability and evaluation of syndrome models. As for the clinical consistency criteria of traditional Chinese and western medicine established in this paper, the animal model with 100% consistency has not been calculated due to the conditions of incomplete symptoms and syndromes described in the studies and different selection indicators. Consequently, the establishment of a simple, easy-to-use, and affordable T2DM animal model with both traditional Chinese and western medicine disease characteristics and the improvement of the Chinese and western medicine evaluation system for different evidence types are of great significance for the future development of TCM research on T2DM.
