ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough (AC) by Xiaoer Huatan Zhike granules (XEHT) based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin (OVA) and 100 mg aluminum hydroxide, a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model, low-, medium- and high-dose (1, 5, 20 g·kg-1, respectively) XEHT, and sodium montelukast (1 mg·kg-1) groups (n=6), and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage, and those in the blank and model groups received the same volume of normal saline by gavage, 1 time·d-1. After 10 consecutive days of drug administration, the guinea pigs were stimulated by 1% OVA nebulization, and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA) in the bronchoalveolar lavage fluid (BALF) and immunoglobulin G (IgG) and immunoglobulin A (IgA) in the serum. Immunohistochemistry (IHC) was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6, interleukin-1β (IL-1β), and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group, the model group showed increased coughs (P<0.01), elevated levels of CRP, TNF-α, IL-6, and MDA and lowered level of SOD in the BALF (P<0.05, P<0.01), elevated levels of IgA and IgG in the serum (P<0.05, P<0.01), congestion of the lung tissue and infiltration of inflammatory cells, increased expression of IL-6 and TNF-α (P<0.01), large areas of low electron density edema in type Ⅱ epithelial cells, obvious swelling and vacuolization of the organelles, karyopyknosis or sparse and dissolved chromatin, and up-regulated mRNA levels of IL-6, IL-1β, and TNF-α (P<0.01). Compared with the model group, the drug administration groups showed reduced coughs (P<0.01), lowered levels of CRP, TNF-α, IL-6, and MDA and elevated level of SOD in the BALF (P<0.05, P<0.01), alleviated lung tissue congestion, inflammatory cell infiltration, and type Ⅱ epithelial cell injury, and decreased expression of IL-6 and TNF-α (P<0.01). In addition, the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG (P<0.05, P<0.01). The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6, IL-1β, and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α (P<0.05, P<0.01). Phospholipase D, mammalian target of rapamycin (mTOR), and epidermal growth factor receptor family of receptor tyrosine kinase (ErbB) signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D, mTOR, and ErbB signaling pathways.

ObjectiveTo explore the effect of modified Ditan Decoction (涤痰汤) on chronic intermittent hypoxia cognitive function and the potential function mechanism. MethodsTwenty-four Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, and a modified Ditan Decoction group, with eight rats in each group. Rats in the modified Ditan Decoction group were administered the decoction by gavage at 14.8 ml/(kg·d), while the normal group and the model group received the same dose of normal saline. Thirty minutes after daily gavage, the rats in all three groups were placed in an intermittent hypoxia chamber. The oxygen concentration for the model group and the modified Ditan Decoction group was adjusted daily for 8 hours using a computer program to establish the model, while the normal group was exposed to the same airflow rate of ambient air. The intervention was continued for 12 weeks to establish a chronic intermittent hypoxia rat model. The Y-maze test was used to evaluate spatial working memory in the rats. Resting-state functional magnetic resonance imaging (rs-fMRI) was performed to detect whole-brain regional homogeneity (ReHo) and seed-based functional connectivity (FC). Brain regions showing significant differences in rs-fMRI were selected for further analysis. Immunofluorescence was used to detect β-amyloid (Aβ) deposition and the number of ionized calcium-binding adapter molecule 1 (IBA1)-positive microglial cells. Immunohistochemistry was employed to assess the expression of synaptophysin (SYP), the excitatory synapse marker vesicular glutamate transporter 1 (Vglut1), and the inhibitory synapse marker vesicular γ-aminobutyric acid transporter (VGAT). ResultsCompared with the normal group, the model group showed a reduced spontaneous alternation rate in the Y-maze test. The smoothed Z-score standardized regional homogeneity (SzReHo) value in the left entorhinal cortex significantly increased, and the FC value from this seed point to the left basal forebrain significantly reduced. Additionally, the model group exhibited significantly higher Aβ fluorescence intensity and Iba1 positivity in the left entorhinal cortex, decreased expression of SYP, Vglut1, and VGAT, along with an increased Vglut1/VGAT ratio (P<0.05 or P<0.01). Compared to the model group, the modified Ditan Decoction group demonstrated an increased spontaneous alternation rate, a significantly reduced SzReHo value in the left entorhinal cortex, and a significantly increased FC value from this region to the left basal forebrain. Furthermore, this group showed significantly lower Aβ fluorescence intensity and Iba1 positivity in the left entorhinal cortex, increased levels of SYP, Vglut1, and VGAT, and a decreased Vglut1/VGAT ratio (P<0.05 or P<0.01). ConclusionModified Ditan Decoction can reconstruct the projection from the left basal forebrain to the entorhinal cortex in chronic intermittent hypoxia, thereby reducing Aβ aggregation and excessive microglial activation in the left entorhinal cortex. This process improves the excitation/inhibition imbalance caused by synaptic remodeling, ultimately enhancing cognitive function in rats of chronic intermittent hypoxia.

OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance (shorted for “medical alliance”) of Wanzhou District of Chongqing, and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units (5 leading units and 16 member units) of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use, pharmaceutical personnel team construction, the development of pharmaceutical care, and rational use of antibiotics. RESULTS Among the 21 constituent units, 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties, with a total compliance rate of 85.71%; 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount, with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively, and the proportions of personnel with senior professional titles were 8.56% and 1.63%, respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units, and 5 clinical pharmacy information service platforms were established; all 5 leading units were able to regularly carry out clinical pharmacy projects, while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units (4.81%, 5.21%) were significantly higher than those of the 5 leading units (2.80%, 4.00%). CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However, the data on the allocation of pharmaceutical professionals and the number, qualifications, and job titles of clinical pharmacists in member units are generally low. Moreover, the pharmaceutical service projects and service quality in member units need to be further improved.

ObjectiveLeveraging the advanced capabilities of nanopore long-read sequencing technology, our study undertook a comprehensive analysis of the distinct transcriptomic alterations occurring in normal liver parenchymal cells and liver cancer cells subjected to hypoxic conditions. The primary goal was to elucidate the underlying mechanisms governing tumor cell survival and metastasis in low-oxygen environments, thereby paving the way for innovative targeted cancer therapies. MethodsThe normal liver parenchymal cell line THLE-3 and the hepatocellular carcinoma cell line Hep3B were chosen as the focal points of this investigation. Following a 48-hour incubation period in both normoxic and hypoxic conditions, total RNA was extracted from these cells. Subsequently, we employed nanopore sequencing technology to conduct a high-throughput, high-fidelity analysis of the transcriptomes of these two cell lines across different oxygen levels. ResultsThis study established a hypoxic transcriptome dataset using third-generation nanopore sequencing technology, achieving an unprecedented level of sequencing accuracy. By conducting a Gene Ontology (GO) enrichment analysis, we systematically identified and explored the key biological pathways associated with the hypoxic response (P<0.05). Furthermore, we integrated molecular dynamics simulation techniques to gain deeper insights into the dynamic structural changes of Solute Carrier Family 1 Member 5 (SLC1A5) during the translation of hypoxic-specific subtypes, providing direct evidence to elucidate its functional regulation. ConclusionThe application of nanopore long-read sequencing technology has proven to be a powerful tool, not only successfully capturing the distinctive expression patterns and specific subtypes of mRNA under hypoxic conditions, but also offering robust technical support for delving into the intricate transcriptomic landscape of hypoxic microenvironments. By further integrating protein structure simulations and molecular dynamics, we have proposed novel avenues for exploring protein structures in hypoxic microenvironments. The findings of this study have significantly enriched the field of hypoxic-specific transcriptomics, providing a more reliable data foundation for investigating hypoxic-specific protein structures. Moreover, these discoveries have unveiled potential hypoxic-specific targets that could be harnessed for the development of future targeted cancer treatment strategies.

In recent years, gastrointestinal stromal tumors (GIST) have increased incidence and mortality, and most GIST is caused by the activation mutation of the c-KIT gene. Therefore, c-KIT has become a promising therapeutic target of GIST. At present, the drugs approved for the treatment of GIST including imatinib, sunitinib, regorafenib and ripretinib, are mostly prone to developing resistance and accompanied by various degrees of adverse reactions. Therefore, there is an urgent need to develop new c-KIT inhibitors to solve the problem of resistance. In this study, we investigated the anti-tumor effect of a novel c-KIT inhibitor PN17-1 on gastrointestinal stromal tumor GIST-882 cells
