Traditional Chinese medicine and its bioactive components have garnered increasing attention as potential therapeutic options for allergic asthma. By targeting the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, these natural compounds exhibit unique advantages in multilevel immunomodulation and inflammation suppression compared with single-target synthetic drugs. Accumulating pharmacological evidence supports their capacity to restore pathway homeostasis, positioning them as promising candidates for complementary strategies in asthma management. Allergic asthma, a heterogeneous respiratory disorder affecting approximately 150 million individuals worldwide, arises from a complex interplay of genetic predisposition, environmental exposures, and lifestyle factors. Its pathological progression is marked by aberrant activation of the PI3K/AKT signaling cascade, with the mechanistic target of rapamycin serving as a key downstream regulatory node. This evolutionarily conserved pathway orchestrates fundamental cellular processes that contribute to three hallmark pathological features of allergic asthma: chronic airway inflammation, structural remodeling of the bronchial architecture, and airway hyperresponsiveness. This review has 3 primary objectives: (1) to evaluate the role of the PI3K/AKT pathway in allergic asthma pathogenesis, (2) to analyze the molecular mechanisms of representative traditional Chinese medicine preparations and their active ingredients, and (3) to identify novel bioactive inhibitors derived from natural products. Collectively, these investigations provide a conceptual framework for the development of next-generation targeted therapies and for optimizing clinical management strategies for allergic asthma.

It has been popular and challenging to undertake researches on the delay of acquired resistance of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI). As key cells for tumor initiation, cancer stem cells (CSC) play an important role in the process of resistance to EGFR-TKI. Although preliminary studies found that traditional Chinese medicine (TCM) could inhibit CSC properties and delay EGFR-TKI resistance, the specific molecular mechanism remains unclear. By summarizing the empirical syndrome treatment of EGFR-TKI resistance via TCM and combining recent researches on TCM intervention in CSC to delay EGFR-TKI resistance, this review discussed the potential molecular pathways and mechanisms of deceleration in resistance to EGFR-TKI by TCM via inhibiting CSC characteristics, in order to expand the research ideas of TCM in combination with targeted therapy.

Objective To investigate the effects of sodium-glucose cotransporter 2 inhibitor (SGLT2i)canagliflozin and epithelial sodium channel inhibitor amiloride or benzamil in combination on the bone metabolism in the rats with the nephrotic syndrome (NS) induced by doxorubicin. Methods In the 49 male SD rats selected, 7 were randomly selected as control group (NG), and 42 were built as adriamycin-induced nephropathy model by injecting adriamycin through the tail vein, and were randomly divided into model group (MG group), canagliflozin group (KG group), benzamil group (BH group), amiloride group (AL group), canagliflozin+benzamil group (KB group) and canagliflozin+amiloride group (KA group), with 7 cases in each group. Each medication group was given intragastric administration according to the body weight of rats regularly every day, NG group and MG group were given equal amount of normal saline, the course of treatment was 6 weeks. The 24-hour urinary protein (24 h-UTP) of each group was detected one day before treatment to verify the successful preparation of the model. At 6 weeks after treatment, the 24 h-UTP, urine sodium (UNa), urinary potassium (UK) levels in urine and the albumin (ALB), triglyceride (TG), cholesterol (TC), low density lipoprotein (LDL), serum calcium (SCa), sodium (SNa), potassium (SK), 25-hydroxyvitamin D (25-OH-D), alkaline phosphatase (ALP), parathyroid hormone (PTH), procollagen type Ⅰ N-terminal propeptide (PINP) and beta C-terminal cross-linked telopeptides of typeⅠ collagen (β-CTX) levels in serum were measured, respectively. Results After successful modeling, the levels of 24 h-UTP, TG, TC, LDL and SCa in the MG group were significantly increased, while the levels of ALB, 25-OH-D, ALP, PINP and PTH were significantly decreased (P < 0.05 or P < 0.01). After 6 weeks of drug intervention, the body mass of rats treated with KG alone decreased significantly (P < 0.05). Compared with the MG group, the levels of 24 h-UTP, TC, TG, LDL and SCa were significantly decreased, and the level of ALB was significantly increased in all drug groups when compared to the MG (P < 0.05 or P < 0.01). Compared with the MG group, the levels of 25-OH-D, ALP, PINP and β-CTX in the KA group were significantly increased when compared to the MG (P < 0.05 or P < 0.01). Molding and drug therapy had no impact on levels of UNa, UK, SK and SNa (P>0.05). Conclusion Calaglizin alone, benzamil alone, amiloride alone and calaglizin combined with benzamil or amiloride can improve the mass proteinuria, hypoproteinemia and hyperlipidemia in adriamycin-induced NS model rats. The combination of caraglipzin and amiloride has a significant osteogenic or osteoclastic effect, which may play a role in reducing the risk of fracture in NS rats by forming a new osteogenic/osteoclastic balance.

Identification of the risk factors for conversion to cesarean section during labor can significantly improve the mother and infant outcomes. Though advocated by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), intrapartum ultrasound is not widely practiced in managing labor progress. The Obstetrics and Gynecology Center of Zhujiang Hospital of Southern Medical University has carried out intrapartum ultrasound in recent years. We summarize the clinical key point and the significance of measuring the major sonographic parameters during labor and illustrate the role of occiput-spine angle, a new sonographic index, in predicting fetal head descent during the first stage of labor.
