ObjectiveTo investigate the effect of Niuhuang Qingxinwan (NHQXW) in improving intracerebral hemorrhage (ICH) with Tanre Fushi (phlegm-heat and fu-organ excess) syndrome by maintaining blood-brain barrier (BBB) integrity, and to explore its potential mechanism. MethodsMale mice were administered with 15% autologous feces for 3 consecutive days to simulate spontaneous Tanre Fushi syndrome, followed by surgical induction of collagenase-induced ICH on the fourth day. Mice were randomly assigned to seven groups: Sham, Sham+NHQXW-H, collagenase, collagenase+feces, and NHQXW intervention groups at low (NHQXW-L, 0.225 g·kg-1), medium (NHQXW-M, 0.45 g·kg-1), and high (NHQXW-H, 0.9 g·kg-1) doses. Treatments were administered for 3 days after surgery. NHQXW effects on Tanre Fushi syndrome were assessed via fecal water content and small intestinal carbon propulsion rate. Protective effects of NHQXW against ICH with Tanre Fushi syndrome were evaluated by measuring hematoma volume, neurological deficits, and brain water content. BBB integrity was further assessed using Evans blue staining, hematoxylin-eosin (HE) staining, immunofluorescence, and Western blot for Claudin-5, plasmalemma vesicle-associated protein (PLVAP), matrix metalloproteinase (MMP)-2, and MMP-9. The potential mechanism of NHQXW was investigated by detecting protein expression of protein kinase B (Akt), extracellular signal-regulated kinase 1/2 (ERK1/2), signal transducer and activator of transcription 3 (STAT3), Yes-associated protein (YAP), and their phosphorylated forms. ResultsCompared with the collagenase+feces group, NHQXW-M and NHQXW-H significantly reduced fecal water content (P<0.05, P<0.01) and intestinal propulsion rate (P<0.01), alleviated neurological deficits (P<0.01), decreased hematoma volume (P<0.01) and Evans blue extravasation (P<0.01), increased Claudin-5 protein expression (P<0.05, P<0.01) and fluorescence intensity (P<0.01), and decreased PLVAP protein expression (P<0.01) and fluorescence intensity (P<0.05, P<0.01), as well as MMP-2 (P<0.05, P<0.01) and MMP-9 (P<0.01) expression. NHQXW-H downregulated p-Akt (P<0.05), p-ERK1/2 (P<0.05), p-STAT3 (P<0.01), and p-YAP (P<0.05), with the most significant effect observed on STAT3 phosphorylation. ConclusionNHQXW effectively alleviates neurological deficits and BBB injury in ICH mice with Tanre Fushi syndrome, primarily by inhibiting STAT3 activation.

OBJECTIVES:
According to the World Health Organization (WHO), infertility rates have been steadily rising worldwide. Identifying risk factors for contrast agent reflux into the myometrium during hysterosalpingo-contrast sonography (HyCoSy) is of clinical significance in reducing this complication and improving infertility treatment. However, there is currently no standardized pre-evaluation method for predicting intra-myometrial contrast reflux, with clinical assessment often relying on physician experience and patient symptoms. This study aims to identify imaging risk factors for contrast agent reflux into the myometrium using four-dimensional (4D) HyCoSy and to construct a nomogram-based predictive model to assist in clinical decision-making.
METHODS:
A retrospective analysis was conducted on 1 274 infertile women who underwent 4D HyCoSy at the Women and Children's Hospital of Hunan and the the Third Xiangya Hospital of Central South University from January 1, 2020, to December 15, 2022. Patients were divided into a reflux group (n=234) and a non-reflux group (n=1 040) based on the presence of intra-myometrial contrast reflux. Univariate and multivariable Logistic regression analyses were used to identify significant predictors, which were then used to construct a nomogram model. Internal validation was performed using 500 bootstrap resamples.
RESULTS:
The age of the reflux group was significantly higher than that of the non-reflux group [(31.82±5.27) years vs (30.66±4.83) years, P=0.001 1]. Primary infertility was more common in the non-reflux group (50.96%), while secondary infertility dominated in the reflux group (76.50%), with 72.65% having a history of gynecological surgery (P<0.001). Abnormal menstrual volume and discomfort during the procedure were more common in the reflux group, while the non-reflux group tolerated higher contrast agent doses (P<0.001). Imaging differences included endometrial thickness, tubal wall smoothness, and peritoneal contrast dispersion, with the non-reflux group showing thicker endometrium and smoother, more patent tubes. The nomogram model yielded an area under the curve (AUC) of 0.854, indicating good predictive performance. The AUC of the decision curve analysis (DCA) for internal validation of the model was 0.737. When the threshold probability for contrast agent reflux into the myometrium ranged from 0.05 to 0.95, the maximum net benefit reached 0.18. The net benefit of applying the nomogram predictive model exceeded that of either full intervention or no intervention, indicating that the model demonstrates good clinical predictive performance.
CONCLUSIONS
The nomogram model, based on infertility type, endometrial thickness, contrast agent dose, and discomfort symptoms, effectively predicts intra-myometrial contrast agent reflux after 4D HyCoSy. It provides a valuable tool for clinicians to implement early preventive measures and reduce the risk of contrast leakage and associated complications.

Stroke is a neurological disease characterized by cerebral ischemia or hemorrhagic injury, leading to death and disability worldwide. At present, there is still a lack of neuroprotective drugs for the treatment of stroke. Niuhuang Qingxin pills are Chinese patent medicine recommended by guidelines and expert consensus for preventing and treating stroke. Studies have shown that Niuhuang Qingxin pills have sedative, anticonvulsant, antipyretic, and other pharmacological effects. Moreover, the main components, such as flavonoids, phenolic acids, and saponins, also exhibit strong pharmacological activities which can improve stroke-induced nerve damage. Studies have confirmed that representative ingredients such as baicalin and ginsenosides can interfere with multiple pathological events, including blood-brain barrier destruction, oxidative stress, inflammatory response, apoptosis, and autophagy, and the mechanisms of the essential ingredients are related to the action on important targets such as Kelch-like ECH-associated protein 1 (Keap1), matrix metalloproteinase-9 (MMP-9), and high-mobility group box 1 (HMGB1), and involvement in the regulation of Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB), nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), and phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathways. This article summarized the research status of Niuhuang Qingxin pills and the experimental pharmacological progress of common ingredients in the prevention and treatment of stroke to provide clues for further research into Niuhuang Qingxin pills and the development of active ingredients of traditional Chinese medicines.
