ObjectiveTo observe the mechanism of Guihuang formula in regulating the activation of NOD-like receptor protein 3 (NLRP3) inflammasome and inhibiting pyroptosis in the treatment of type Ⅲ prostatitis. Methods(1) In an animal experiment, 50 Sprague Dawley (SD) rats were randomly divided into a blank group, a model group, and low-dose, medium-dose, and high-dose groups of Guihuang formula, with 10 rats in each group. Except for the blank group, the type Ⅲ prostatitis rat model was prepared for the other four groups.After the modeling was successful, the blank group and the model group were given normal saline intragastrically, and the low-dose, medium-dose, and high-dose groups of Guihuang formula were given intragastrically with Guihuang formula (4.9, 9.8, 19.6 g·kg-1). After 30 days of intragastrical administration, samples were taken for detection. Inflammatory cell infiltration in prostate tissue was observed by hematoxylin-eosin (HE) staining, and serum IL-1β and IL-18 levels were measured by enzyme-linked immunosorbent assay (ELISA). Serum malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) levels were determined by biochemistry. NLRP3 expression in prostate tissue was assessed by immunohistochemistry, and the expression of NLRP3, cysteine-aspartic acid protease-1 (Caspase-1), and gasdermin D (GSDMD) in prostate tissue was measured by Western blot. (2) In a cell experiment, human normal prostate epithelial cells (RWPE-1 cells) were divided into a blank group, a model group, a Guihuang formula group, and an NLRP3 inhibitor group (MCC950 group). Except for the blank group, the other three groups were stimulated by 100 μg·L-1 lipopolysaccharide (LPS) for 4 h and 5 mol·L-1 adenosine triphosphate (ATP) for 30 min to prepare the pyroptosis model. After successful modeling, blank serum was given to the blank group and the model group. 6.25 μg·mL-1 Guihuang formula drug-containing serum was added to the Guihuang formula group, and MCC950 was added to the MCC950 group on the basis of the model group. Propidium iodide (PI) uptake and Caspase-1 expression were detected by flow cytometry, and lactate dehydrogenase (LDH) level in the cell supernatant was measured by biochemistry. Interleukin (IL)-1β and IL-18 levels of the cell supernatant were determined by ELISA, and the expression of NLRP3, Caspase-1, and GSDMD was detected in Western blot. Results(1) For the animal experiment, compared with the blank group, the model group showed significant infiltration of inflammatory cells in prostate tissue, while the low-dose, medium-dose, and high-dose groups of Guihuang formula showed reduced infiltration of acinar inflammatory cells, reduced degree of glandular epithelial degeneration and interstitial edema, and significantly reduced degree of damage. Compared with those in the blank group, the levels of IL-1β and IL-18 in the serum of the model group were significantly increased (P<0.01). Compared with the model group, the low-dose, medium-dose, and high-dose groups of Guihuang formula showed a significant decrease in serum IL-1β and IL-18 levels (P<0.01). Compared with that in the blank group, the serum MDA level in the model group significantly increased (P<0.01). Compared with that in the model group, the MDA level in the low-dose, medium-dose, and high-dose groups of Guihuang formula was significantly reduced (P<0.01). Compared with those in the blank group, the levels of SOD and GSH-Px in the serum of the model group significantly decreased (P<0.05). Compared with the model group, the low-dose, medium-dose, and high-dose groups of Guihuang formula showed a significantly increase in SOD (P<0.01). Compared with the model group, the low-dose, medium-dose, and high-dose groups of Guihuang formula showed a significantly increase in GSH-Px (P<0.05). Immunohistochemistry showed that compared with the blank group, the model group had high expression of NLRP3 molecule in prostate tissue. The expression of NLRP3 in the low-dose, medium-dose, and high-dose groups of Guihuang formula was significantly lower than that in the model group. Compared with those in the blank group, the expression levels of NLRP3, Caspase-1, and GSDMD proteins in the prostate tissue of the model group were significantly increased (P<0.01). Compared with those in the model group, the expression levels of NLRP3, Caspase-1, and GSDMD proteins in the low-dose, medium-dose, and high-dose groups of Guihuang formula were significantly inhibited (P<0.01). (2) For the cell experiment, compared with that in the blank group, the PI uptake rate of RWPE-1 cells in the model group significantly increased (P<0.01). Compared with that in the model group, the PI uptake rate of the Guihuang formula group and the inhibitor group significantly decreased (P<0.01). Compared with that in the blank group, the expression of Caspase-1 in the model group was significantly higher (P<0.01). Compared with that in the model group, the Caspase-1 in the Guihuang formula group and the inhibitor group significantly decreased (P<0.01). Compared with the blank group, the model group showed an increase in LDH release (P<0.01). Compared with the model group, the Guihuang formula group and the inhibitor group showed a significantly decrease in LDH release (P<0.01). Compared with those in the blank group, the levels of IL-1β and IL-18 in the supernatant of the model group were significantly increased (P<0.01). Compared with the model group, the Guihuang formula group and the inhibitor group showed a significantly decrease in the levels of IL-1β and IL-18 (P<0.01). Compared with those in the blank group, the expression levels of NLRP3, Caspase-1, and GSDMD proteins significantly increased in the model group (P<0.01). Compared with those in the model group, the protein expression levels of NLRP3, Caspase-1, and GSDMD were significantly reduced in the Guihuang formula group and inhibitor group (P<0.01). ConclusionGuihuang formula can inhibit the activation of Caspase-1, prevent GSDMD cleavation and lysis, and inhibit cell pyrodeath in the treatment of type Ⅲ prostatitis by inhibiting the activation of NLRP3 inflammasome.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland (HMG). METHODS Female SD rats were divided into control group and HMG group according to body weight, with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling, two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid (calculated by crude drug) intragastrically, once a day, for 7 consecutive days. Blood samples were collected before the first administration (0 h), and at 5, 15, 30 minutes and 1, 2, 4, 8, 12, 24 hours after the last administration, respectively. Using chlorzoxazone as the internal standard, the plasma concentrations of ferulic acid, paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve (AUC0-24 h, AUC0-∞), mean residence time (MRT0-∞), half-life (t1/2), peak time (tmax), peak concentration (cmax)] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group, the AUC0-24 h, AUC0-∞ and cmax of ferulic acid in the HMG group were significantly increased (P<0.05); the AUC0-24 h, AUC0-∞ , MRT0-∞ , t1/2 and cmax of paeoniflorin increased, but there was no significant difference between 2 groups (P>0.05); the AUC0-24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged (P<0.05). C ONCLUSIONS In HMG model rats, the exposure of ferulic acid, paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase, and the retention time of rosmarinic acid is significantly prolonged.

Background:
and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking.
Methods:
This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance.
Results:
Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal.
Conclusions
The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Following the core outcome set standards for development(COS-STAD), this study aims to construct core outcome set(COS) for clinical research on traditional Chinese medicine(TCM) treatment of simple obesity. Firstly, a comprehensive review was conducted on the randomized controlled trial(RCT) and systematic review(SR) about TCM treatment of simple obesity that were published in Chinese and English databases to collect reported outcomes. Additional outcomes were obtained through semi-structured interviews with patients and open-ended questionnaire surveys for clinicians. All the collected outcomes were then merged and organized as an initial outcome pool, and then a preliminary list of outcomes was formed after discussion by the working group. Subsequently, two rounds of Delphi surveys were conducted with clinicians, methodology experts, and patients to score the importance of outcomes in the list. Finally, a consensus meeting was held to establish the COS for clinical research on TCM treatment of simple obesity. A total of 221 RCTs and 12 SRs were included, and after integration of supplementary outcomes, an initial outcome pool of 141 outcomes were formed. Following discussions in the steering advisory group meeting, a preliminary list of 33 outcomes was finalized, encompassing 9 domains. Through two rounds of Delphi surveys and a consensus meeting, the final COS for clinical research on TCM treatment of simple obesity was determined to include 8 outcomes: TCM symptom scores, body mass index(BMI), waist-hip ratio, waist circumference, visceral fat index, body fat rate, quality of life, and safety, which were classified into 4 domains: TCM-related outcomes, anthropometric measurements, quality of life, and safety. This study has preliminarily established a COS for clinical research on TCM treatment of simple obesity. It helps reduce the heterogeneity in the selection and reporting of outcomes in similar clinical studies, thereby improving the comparability of research results and the feasibility of meta-analysis and providing higher-level evidence support for clinical practice.

This paper explored the specific mechanism of ginsenoside Rg_1 in regulating mitochondrial fusion through the neurogenic gene Notch homologous protein 1(Notch1) pathway to alleviate hypoxia/reoxygenation(H/R) injury in HL-1 cells. The relative viability of HL-1 cells after six hours of hypoxia and two hours of reoxygenation was detected by cell counting kit-8(CCK-8). The lactate dehydrogenase(LDH) activity in the cell supernatant was detected by the lactate substrate method. The content of adenosine triphosphate(ATP) was detected by the luciferin method. Fluorescence probes were used to detect intracellular reactive oxygen species(Cyto-ROS) levels and mitochondrial membrane potential(ΔΨ_m). Mito-Tracker and Actin were co-imaged to detect the number of mitochondria in cells. Fluorescence quantitative polymerase chain reaction and Western blot were used to detect the mRNA and protein expression levels of Notch1, mitochondrial fusion protein 2(Mfn2), and mitochondrial fusion protein 1(Mfn1). The results showed that compared with that of the control group, the cell activity of the model group decreased, and the LDH released into the cell culture supernatant increased. The level of Cyto-ROS increased, and the content of ATP decreased. Compared with that of the model group, the cell activity of the ginsenoside Rg_1 group increased, and the LDH released into the cell culture supernatant decreased. The level of Cyto-ROS decreased, and the ATP content increased. Ginsenoside Rg_1 elevated ΔΨ_m and increased mitochondrial quantity in HL-1 cells with H/R injury and had good protection for mitochondria. After H/R injury, the mRNA and protein expression levels of Notch1 and Mfn1 decreased, while the mRNA and protein expression levels of Mfn2 increased. Ginsenoside Rg_1 increased the mRNA and protein levels of Notch1 and Mfn1, and decreased the mRNA and protein levels of Mfn2. Silencing Notch1 inhibited the action of ginsenoside Rg_1, decreased the mRNA and protein levels of Notch1 and Mfn1, and increased the mRNA and protein levels of Mfn2. In summary, ginsenoside Rg_1 regulated mitochondrial fusion through the Notch1 pathway to alleviate H/R injury in HL-1 cells.

PURPOSE:
To analyze risk factors for severe trauma and establish a nomogram for early risk prediction, to improve the early identification of severe trauma.
METHODS:
This study was conducted on the patients treated in 81 trauma treatment institutions in Gansu province from 2020 to 2022. Patients were grouped by year, with 5364 patients from 2020 to 2021 as the training set and 1094 newly admitted patients in 2020 as the external validation set. Based on the injury severity score (ISS), patients in the training set were classified into 2 subgroups of the severe trauma group (n = 478, ISS scores ≥25) and the non-severe trauma group (n = 4886, ISS scores <25). Univariate and binary logistic regression analyses were employed to identify independent risk factors for severe trauma. Subsequently, a predictive model was developed using the R software environment. Furthermore, the model was subjected to internal and external validation via the Hosmer-Lemeshow test and receiver operating characteristic curve analysis.
RESULTS:
In total, 6458 trauma patients were included in this study. Initially, this study identified several independent risk factors for severe trauma, including multiple traumatic injuries (polytrauma), external hemorrhage, elevated shock index, elevated respiratory rate, decreased peripheral oxygen saturation, and decreased Glasgow coma scale score (all p < 0.05). For internal validation, the area under the receiver operating characteristic curve was 0.914, with the sensitivity and specificity of 88.4% and 87.6%, respectively; while for external validation, the area under the receiver operating characteristic curve was 0.936, with the sensitivity and specificity of 84.6% and 93.7%, respectively. In addition, a good model fitting was observed through the Hosmer-Lemeshow test and calibration curve analysis (p > 0.05).
CONCLUSION
This study establishes a nomogram for early risk prediction of severe trauma, which is suitable for primary healthcare institutions in underdeveloped western China. It facilitates early triage and quantitative assessment of trauma severity by clinicians prior to clinical interventions.

OBJECTIVE:
To investigate the efficacy and safety of transurethral water vapor thermal therapy (WVTT) using the Rezūm system for benign prostatic hyperplasia (BPH) in the real world.
METHODS:
A total of 181 patients with BPH were recruited from the Second Affiliated Hospital of Nanjing Medical University from August 2022 to December 2023, of whom 173 patients were treated with WVTT using the Rezūm system, while 8 patients were treated with WVTT combined with TURP. They were followed up at 1, 3, and 6 months postoperatively to assess changes in the IPSS, QoL, Qmax, IIEF-5, and the occurrence of any complications. Results: All 181 surgeries in this group were successfully completed. The operation time of the Rezūm system was (4.6 ± 1.4) minutes. The postoperative indwelling catheterization time was (8.0 ± 2.1) days. With a follow-up of at least 6 months, there was a significant decrease in PV, IPSS and QoL, and a remarkable increase had been found in Qmax as well (P<0.05). There was no significant difference in IIEF-5 before and after the operation (P>0.05). In this groups of patients, postoperative complications mainly included 95 cases (52.5%) of gross hematuria, 6 cases (3.3%) of retrograde ejaculation, 5 cases (2.8%) of urethral stricture, 4 cases (2.2%) of prostatitis, and 10 cases (5.5%) of urinary tract infection. Four cases (2.2%) underwent surgical retreatment for BPH after surgery.
CONCLUSION
In the real world, the use of Rezūm thermal steam ablation system for the treatment of BPH has satisfactory short-term effect, short surgical time, and significant improvement in IPSS, QoL, Qmax, which does not adversely affect sexual function.
