ObjectiveTo investigate the efficacy of Xingpi capsules (XPC) in treating diarrhea-predominant irritable bowel syndrome (IBS-D) with spleen deficiency and elucidate its potential molecular mechanisms. MethodsA rat model of IBS-D with spleen deficiency was established by administering senna leaf in combination with restrained stress and swimming fatigue for 14 d. Ten specific pathogen free (SPF)-grade healthy rats were used as the normal control group. After successful modeling, SPF-grade rats were randomly divided into a model group, a pinaverium bromide group (1.5 mg·kg-1), and low- and high-dose XPC groups (0.135 and 0.54 g·kg-1), with 10 rats in each group. Rats in the normal control group and the model group were given distilled water by gavage, while the remaining groups were administered corresponding drug solutions by gavage once a day for 14 consecutive days. The rat body weights and fecal condition were observed every day, and the Bristol score was recorded. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of 5-hydroxytryptamine (5-HT) in serum and colon tissue. Transmission electron microscopy was used to observe the microvilli and tight junctions in the colon. The integrity of the colonic barrier, intestinal motility, and expression of related pathway proteins were evaluated by hematoxylin-eosin (HE) staining, immunohistochemistry, and Western blot. ResultsCompared with those in the normal control group, rats in the model group showed a significantly decreased body weight and increased diarrhea rate, diarrhea grade, and Bristol score (P<0.01). HE staining revealed incomplete colonic mucosa in the model group, with evident congestion and edema observed. Electron microscopy results indicated decreased density and integrity of the colonic barrier, shedding and disappearance of microvilli, and significant widening of tight junctions. The expression levels of colonic tight junction proteins Occludin and Claudin-5 were downregulated (P<0.01), and the levels of 5-HT in serum and colon tissue were elevated (P<0.01). The small intestine propulsion rate significantly increased (P<0.01), and the expression of contractile proteins Ras homolog family member A (RhoA) and Rho-associated coiled-coil containing protein kinase 2 (ROCK2) in colon and phosphorylation of myosin light chain (MLC20) were upregulated (P<0.01). Compared with the model group, the treatment groups showed alleviated diarrhea, diarrhea-associated symptoms, and pathological manifestations of colon tissue to varying degrees. Specifically, high-dose XPC exhibited effectively relieved diarrhea, promoted recovery of colonic mucosal structure, significantly reduced congestion and edema, upregulated expression of Occludin and Claudin-5 (P<0.01), decreased levels of 5-HT in serum and colon tissue (P<0.05,P<0.01), significantly slowed small intestine propulsion rate (P<0.01), and significantly downregulated expression of contractile proteins RhoA and ROCK2 in colon and phosphorylation of MLC20 (P<0.05,P<0.01). ConclusionXPC effectively alleviates symptoms of spleen deficiency and diarrhea and regulates the secretion of brain-gut peptide. The characteristics of XPC are mainly manifested in alleviating IBS-D with spleen deficiency from the aspects of protecting intestinal mucosa and inhibiting smooth muscle contraction, and the mechanism is closely related to the regulation of the 5-HT-RhoA/ROCK2 pathway expression.

ObjectiveWith the development of society and the increasing demand for pregnancy at an advanced age, diminished ovarian reserve (DOR) has attracted wider attention. This disease affects the normal menstruation of women and poses a threat to their mental health. Current research on DOR is still in the initial stage, and advancing research progress in DOR necessitates the construction of effective and clinically relevant animal models. Building on existing literature and integrating the diagnosis criteria of DOR in traditional Chinese medicine (TCM) and Western medicine, this study summarized, analyzed, and evaluated existing models, providing a reference for optimizing DOR animal models. MethodsA retrospective analysis of literature on DOR-related animal models was conducted, and the diagnostic criteria of DOR in TCM and Western medicine were sorted out. By means of evaluation methods of animal models, the clinical relevance of each model to TCM and Western medicine was assessed. ResultsDOR animal models included those based on natural factors, iatrogenic factors, immune factors, metabolic factors, and environmental factors. Among them, the model based on iatrogenic factors, especially models induced by Tripterygium wilfordii preparations, cyclophosphamide, and cisplatin, had a high degree of relevance to both Western medical diseases and TCM syndromes and was confirmed as the optimal modeling method for studying DOR at present. ConclusionThe existing DOR modeling methods mostly have a high degree of clinical relevance to Western medical diseases, while the number of DOR animal models with clear TCM syndromes is very limited. TCM plays an indispensable role in exploring DOR treatment methods. Therefore, the development of DOR animal models related to TCM syndromes should be strengthened, further exploring the potential of TCM and providing strong theoretical support for the application of TCM in DOR treatment.

A 36-year-old male developed unconsciousness and no response to voice stimuli after taking approximately 2 050 mg felodipine (the specific time was unknown). Two hours later, he was sent to the department of emergency by his family and admitted to the hospital. His vital signs showed body temperature 35.1 ℃, pulse 148 times/min, respiration 32 times/min, and blood pressure 65/34 mmHg. Acute drug poisoning, acute toxic cardiomyopathy, acute toxic shock, acute type Ⅱ respiratory failure, acute toxic encephalopathy, and acute renal failure were diagnosed based on the patient′s clinical manifestations combined with laboratory tests results, cardiac ultrasound, chest and abdominal CT scans. Endotracheal intubation connected to a ventilator for invasive assisted ventilation, pressure boosting, and fluid resuscitation were given. At the same time, repeated gastric lavage and enema were performed to remove toxins. Blood perfusion was intermittently and repeatedly administered, and continuous renal replacement therapy was used. The blood concentration of felodipine was 1 298 μg/L at 2 hours after admission, and cardiac arrest occurred at 4 hours. Venous-arterial extracorporeal membrane oxygenation (V-A ECMO) treatment was administered immediately. After 48 hours of ECMO operation, sedatives were discontinued and the patient′s consciousness was improved after 4 hours. On the 5th day of ECMO treatment, his heart rate was 72 beats per minute, and blood pressure was 127/65 mmHg. The blood concentration of felodipine decreased to 2 μg/L. The patient′s vital signs were significantly improved and ECMO supportive treatment was withdrawn. After 26 days of hospitalization, the patient recovered and was discharged.

Objective:
To evaluates the association between maternal overweight/obesity during pregnancy and offspring risk of metabolic dysfunction associated steatotic liver disease (MASLD), providing theoretical evidence for early life MASLD prevention.
Methods:
An online search was conducted across ten databases (CNKI, Wanfang, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, PQDT Global, ScienceDirect) for research literature on the association between maternal overweight/obesity during pregnancy and the development of MASLD in offspring, with the search period spanning from January 2014 to December 2024. Two researchers independently screened literature, extracted data, and assessed study quality. Statistical analysis was performed using R 4.3.3.
Results:
Ten studies involving 10 229 participants were included, comprising 4 cohort studies and 6 case control studies. Cohort studies showed that maternal overweight and obesity significantly increased offspring MASLD risk ( RR=1.59, 95%CI=1.06-2.39, P <0.05), with moderate heterogeneity ( I 2=56.9%, P =0.07). Case control studies indicated a positive association between maternal overweight/obesity during pregnancy and offspring risk of MASLD( OR=2.00, 95%CI=1.68-2.39, P < 0.05), with low heterogeneity ( I 2=48.8%, P =0.08).
Conclusions
Maternal overweight/obesity during pregnancy positively correlates with offspring MASLD risk. Gestational weight management may reduce the risk.
