ObjectiveThis study aimed to establish a monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH) rat model to systematically evaluate the protective effect of Xiao Qinglongtang (XQLT) on right cardiac function in model rats and further elucidate the underlying regulatory mechanism. MethodsSixty male SD rats were randomly assigned to the normal group, model group, XQLT low-, medium-, and high-dose groups (XQLT-L/M/H), and the beraprost sodium tablet group (BST). Except for the normal group, rats in all other groups were given a single subcutaneous injection of MCT (60 mg·kg-1) to induce PAH. Three weeks after injection, rats in the XQLT-L/M/H groups were administered XQLT intragastrically at 3.07, 6.14, 12.28 g·kg-1·d-1, respectively. Rats in the BST group received beraprost sodium at 12.6 μg·kg-1·d-1, and rats in the model group received an equal volume of saline. All treatments lasted for 3 weeks. Right ventricular systolic pressure (RVSP) was measured by right ventricular catheterization. Cardiac function was assessed by echocardiography. The right ventricle was weighed to calculate the right ventricular hypertrophy index (RVHI). Hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy were used to observe myocardial morphology. Serum metabolomic changes were analyzed using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Data-independent acquisition (DIA) proteomics was used to detect differentially expressed (DE) proteins in the right ventricle, and Western blot was used to measure the expression of uncoupling protein 3 (UCP3), phosphatidylinositol 3-kinase catalytic subunit p110α (PIK3CA), L1 cell adhesion molecule (L1CAM), and quinone oxidoreductase (CRYZ). UPLC-MS/MS was used to analyze the chemical components of XQLT. ResultsCompared with the normal group, the model group showed significantly increased RVSP and RVHI (P<0.05), along with pathological changes in myocardial morphology. Compared with the model group, all XQLT-treated groups exhibited reductions in RVSP and RVHI as well as significant improvements in cardiac function and myocardial morphology. Among the XQLT groups, XQLT-M showed the most pronounced effects (P<0.05), comparable to the BST group. Serum metabolomics revealed 105 differential metabolites in the XQLT groups versus the model group [variable importance in projection (VIP) >1, P<0.05], including 58 upregulated and 47 downregulated metabolites. KEGG enrichment analysis indicated that XQLT intervention downregulated phenylalanine metabolism (P<0.01) and upregulated unsaturated fatty acid biosynthesis (P<0.05). Proteomics analysis showed that 982 DE proteins were identified in the MCT groups versus the normal group, including 455 upregulated and 527 downregulated proteins (|fold change (FC)| >1.3, P<0.05). Compared with the model group, 237 DE proteins were identified in the XQLT groups, including 124 upregulated and 113 downregulated proteins (|FC| >1.3, P<0.05), with 57 overlapping DE proteins. KEGG enrichment suggested that XQLT mainly modulated pathways related to mineral absorption, ribosomal biogenesis, peroxisomes, glycolysis/gluconeogenesis, spliceosomes, and thyroid hormone signaling. Western blot analysis showed that, compared with the model group, XQLT increased the expression of UCP3, PIK3CA, and L1CAM, while decreasing the expression of CRYZ (P<0.05). ConclusionXQLT exerts a protective effect on right heart function in MCT-induced PAH rats, and its mechanism is associated with maintaining myocardial homeostasis and alleviating right ventricular remodeling.

Adipose tissue is a critical energy reservoir in animals and humans, with multifaceted roles in endocrine regulation, immune response, and providing mechanical protection. Based on anatomical location and functional characteristics, adipose tissue can be categorized into distinct types, including white adipose tissue (WAT), brown adipose tissue (BAT), beige adipose tissue, and pink adipose tissue. Traditionally, adipose tissue research has centered on its morphological and functional properties as a whole. However, with the advent of single-cell transcriptomics, a new level of complexity in adipose tissue has been unveiled, showing that even under identical conditions, cells of the same type may exhibit significant variation in morphology, structure, function, and gene expression——phenomena collectively referred to as cellular heterogeneity. Single-cell transcriptomics, including techniques like single-cell RNA sequencing (scRNA-seq) and single-nucleus RNA sequencing (snRNA-seq), enables in-depth analysis of the diversity and heterogeneity of adipocytes at the single-cell level. This high-resolution approach has not only deepened our understanding of adipocyte functionality but also facilitated the discovery of previously unidentified cell types and gene expression patterns that may play key roles in adipose tissue function. This review delves into the latest advances in the application of single-cell transcriptomics in elucidating the heterogeneity and diversity within adipose tissue, highlighting how these findings have redefined the understanding of cell subpopulations within different adipose depots. Moreover, the review explores how single-cell transcriptomic technologies have enabled the study of cellular communication pathways and differentiation trajectories among adipose cell subgroups. By mapping these interactions and differentiation processes, researchers gain insights into how distinct cellular subpopulations coordinate within adipose tissues, which is crucial for maintaining tissue homeostasis and function. Understanding these mechanisms is essential, as dysregulation in adipose cell interactions and differentiation underlies a range of metabolic disorders, including obesity and diabetes mellitus type 2. Furthermore, single-cell transcriptomics holds promising implications for identifying therapeutic targets; by pinpointing specific cell types and gene pathways involved in adipose tissue dysfunction, these technologies pave the way for developing targeted interventions aimed at modulating specific adipose subpopulations. In summary, this review provides a comprehensive analysis of the role of single-cell transcriptomic technologies in uncovering the heterogeneity and functional diversity of adipose tissues.

ObjectiveNeuroinflammation plays a crucial role in both the onset and progression of ischemic stroke, exerting a significant impact on the recovery of the central nervous system. Excessive neuroinflammation can lead to secondary neuronal damage, further exacerbating brain injury and impairing functional recovery. As a result, effectively modulating and reducing neuroinflammation in the brain has become a key therapeutic strategy for improving outcomes in ischemic stroke patients. Among various approaches, targeting immune regulation to control inflammation has gained increasing attention. This study aims to investigate the role of in vitro induced regulatory T cells (Treg cells) in suppressing neuroinflammation after ischemic stroke, as well as their potential therapeutic effects. By exploring the mechanisms through which Tregs exert their immunomodulatory functions, this research is expected to provide new insights into stroke treatment strategies. MethodsNaive CD4+ T cells were isolated from mouse spleens using a negative selection method to ensure high purity, and then they were induced in vitro to differentiate into Treg cells by adding specific cytokines. The anti-inflammatory effects and therapeutic potential of Treg cells transplantation in a mouse model of ischemic stroke was evaluated. In the middle cerebral artery occlusion (MCAO) model, after Treg cells transplantation, their ability to successfully migrate to the infarcted brain region and their impact on neuroinflammation levels were examined. To further investigate the role of Treg cells in stroke recovery, the changes in cytokine expression and their effects on immune cell interactions was analyzed. Additionally, infarct size and behavioral scores were measured to assess the neuroprotective effects of Treg cells. By integrating multiple indicators, the comprehensive evaluation of potential benefits of Treg cells in the treatment of ischemic stroke was performed. ResultsTreg cells significantly regulated the expression levels of both pro-inflammatory and anti-inflammatory cytokines in vitro and in vivo, effectively balancing the immune response and suppressing excessive inflammation. Additionally, Treg cells inhibited the activation and activity of inflammatory cells, thereby reducing neuroinflammation. In the MCAO mouse model, Treg cells were observed to accumulate in the infarcted brain region, where they significantly reduced the infarct size, demonstrating their neuroprotective effects. Furthermore, Treg cell therapy notably improved behavioral scores, suggesting its role in promoting functional recovery, and increased the survival rate of ischemic stroke mice, highlighting its potential as a promising therapeutic strategy for stroke treatment. ConclusionIn vitro induced Treg cells can effectively suppress neuroinflammation caused by ischemic stroke, demonstrating promising clinical application potential. By regulating the balance between pro-inflammatory and anti-inflammatory cytokines, Treg cells can inhibit immune responses in the nervous system, thereby reducing neuronal damage. Additionally, they can modulate the immune microenvironment, suppress the activation of inflammatory cells, and promote tissue repair. The therapeutic effects of Treg cells also include enhancing post-stroke recovery, improving behavioral outcomes, and increasing the survival rate of ischemic stroke mice. With their ability to suppress neuroinflammation, Treg cell therapy provides a novel and effective strategy for the treatment of ischemic stroke, offering broad application prospects in clinical immunotherapy and regenerative medicine.

Objective:To compare the efficacy and safety differences between direct mechanical thrombectomy (abbreviated as direct thrombectomy) and bridging therapy in patients with acute anterior circulation large vessel occlusion and atrial fibrillation.Methods:A retrospective collection of data was conducted for hospitalized patients who underwent mechanical thrombectomy due to acute anterior circulation large vessel occlusion with atrial fibrillation at the First Affiliated Hospital of Soochow University and Suzhou Kowloon Hospital, Shanghai Jiao Tong University School of Medicine from January 1, 2018 to December 31, 2022. Patients were divided into direct thrombectomy and bridging therapy groups based on whether intravenous thrombolysis was used, and the clinical outcomes and safety indicators of the two groups were compared. The primary clinical outcomes included the modified Rankin Scale (mRS) score at 90 days and the proportion of patients with neurological independence at 90 days (the proportion of patients with mRS scores of 0-2). Safety indicators included 90-day mortality rate, intracranial hemorrhage rate, symptomatic intracranial hemorrhage [deterioration of neurological function and an increase of ≥4 points in the National Institutes of Health Stroke Scale (NIHSS) score] rate, and pneumonia incidence. Using the 90-day prognosis as a dependent variable, a binary Logistic regression analysis was conducted to investigate the factors influencing poor prognosis in patients at 90 days.Results:Among the 534 screened patients, 125 were included in the study, with 74 in the direct thrombectomy group and 51 in the bridging therapy group. The difference in the mRS scores at 90 days between the direct thrombectomy group and the bridging therapy group was not statistically significant [2 (0, 3) vs 3 (1, 3), Z=-1.444, P=0.149]. The difference in the proportion of patients with independent neurological function at 90 days [66.2% (49/74) vs 47.1% (24/51), χ2=4.561, P=0.033] was statistically significant between the 2 groups. The 90-day mortality rate [5.4% (4/74) vs 9.8% (5/51), χ 2=0.936, P=0.483], the intracranial hemorrhage rate [17.6% (13/74) vs 29.4% (15/51), χ 2=2.437, P=0.119], the symptomatic intracranial hemorrhage rate [12.2% (9/74) vs 23.5% (12/51), χ 2=2.791, P=0.095], and the pneumonia incidence [59.5% (44/74) vs 56.9% (29/51), χ 2=0.084, P=0.772] between the 2 groups showed no statistically significant differences (all P>0.05). The time from admission to puncture was 97 (74, 122) min and 150 (127, 168) min for the direct thrombectomy and bridging therapy groups, respectively, with a statistically significant difference ( Z=-5.846, P<0.001). Binary Logistic regression analysis showed that venous thrombolysis (adjusted OR=3.004, 95% CI 1.057-8.539, P=0.039), NIHSS score at onset (adjusted OR=1.096, 95% CI 1.009-1.191, P=0.030), and pneumonia (adjusted OR=12.814, 95% CI 3.775-43.499, P<0.001) were associated with poor prognosis at 90 days. Conclusion:For patients with acute anterior circulation large vessel occlusion and atrial fibrillation, direct thrombectomy can increase the proportion of neurological independence at 90 days compared to bridging therapy, with no statistically significant differences in safety indicators, which may be related to the shorter time from admission to puncture in the direct thrombectomy group.

Objective:To explore the clinical features and molecular characteristics of myeloproliferative neoplasms (MPNs) patients with NFE2 gene mutations.Methods:Gene targeted sequencing was used to detect NFE2 gene mutation in 723 patients diagnosed with MPNs who were admitted to Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College between April 2021 and June 2023. The association between NFE2 gene mutations and clinical features and molecular characteristics of MPNs patients were retrospectively analyzed.Results:Among 723 patients with MPNs, NFE2 gene mutations were found in 41 cases (5.7%) . NFE2 gene mutations were predominantly frameshift mutations (44.4%) , followed by nonsense mutations (33.3%) . The median number of mutations in patients with NFE2 gene mutations (4 [2,5]) was higher compared to the group without NFE2 gene mutations (2, [1,3]) ( P<0.001) . NFE2 gene mutations frequently co-occurred with mutations in MPL, ATM, PPM1D, and TET1. NFE2 gene mutations were mostly sub-clonal events, with 80.5% occurring after MPNs driver mutations (JAK2, CALR, or MPL) . NFE2 mutations were correlated with older age [median age: 60 (54, 67) years vs 54 (41, 63) years, P=0.001]. Patients with NFE2 gene mutations had a higher incidence of pre-diagnosis thrombosis (39.0% vs 22.0%, P=0.012) and pre-diagnosis arterial thrombosis (36.6% vs 20.4%, P=0.014) . Using a logistic regression analysis model adjusting for age and comorbidities (including chronic infections, malignancies, and autoimmune diseases) , NFE2 gene mutation was identified as an independent determinant of elevated tumor necrosis factor-alpha (TNF-α) ( OR=2.747, 95% CI: 1.143-6.605, P=0.024) , interferon-gamma (IFN-γ) ( OR=2.689, 95% CI: 1.191-6.076, P=0.017) , IL-10 ( OR=3.219, 95% CI: 1.343-7.717, P=0.009) , IL-12P70 ( OR=3.397, 95% CI:1.003-11.508, P=0.049) , IL-17 ( OR=2.284, 95% CI: 1.017-5.127, P=0.045) . In polycythaemia vera (PV) patients with the NFE2 gene mutation, the proportion of those classified as high-risk is notably higher in both the IWG-PV and mutation-enhanced international prognostic systems for PV (MIPSS-PV) (66.7% vs 25.3% for IWG-PV, P=0.033; 22.2% vs 2.0% for MIPSS-PV, P=0.013) . Similarly, for essential thrombocythaemia (ET) patients, the proportion in the high-risk group of the mutation-enhanced international prognostic systems for ET (MIPSS-ET) is significantly higher (15.4% vs 6.1%, P=0.021) . No statistically significant differences were observed in overall survival or cumulative incidence of thrombosis between NFE2-mutated (38 cases) and non-mutated MPNs patients (671 cases, P>0.05) . Conclusion:NFE2 gene mutations in MPNs were predominantly frameshift mutations. NFE2 gene mutations were correlated with older age, elevated levels of several inflammatory factors (including TNF-α、IFN-γ、IL-10、IL-12P70、IL-17) , and they mostly occurred in late-stage of MPNs.

Objectives:To explore whether short-course radiotherapy (SCRT)-based total neoadjuvant therapy (TNT) combined with PD-1 inhibitors could further promote tumor regression and improve the prognosis.Methods:This is a prospective, multicenter, two-arm randomized controlled, seamless phase Ⅱ/Ⅲ trial for proficient mismatch repair or microsatellite stable (pMMR/MSS) locally advanced rectal cancer (LARC). Eligible patients were randomly assigned to the iTNT (TNT+PD-1) group or the TNT group. Patients in the TNT group received SCRT (5 Gy×5) followed by 4 cycles of CAPOX or 6 cycles of mFOLFOX chemotherapy, with the iTNT group receiving SCRT followed by the same regime in combination with 4 cycles of Sintilimab. Total mesorectal excision (TME) surgery or watch and wait (W&W) was performed after neoadjuvant therapy and then 2 cycles of same regimen as before were recommended. The primary endpoints are the complete response (CR) rate for phase Ⅱ trial and 3-year disease-free survival (DFS) for phase Ⅲ trial. A total of 588 patients will be enrolled for the phase Ⅱ/Ⅲ trial. Short-term efficacy and safety data from the initial 100 treated patients were analyzed as planned.Results:From 2022-8-31 to 2023-5-24 the initial 100 patients were enrolled from 10 hospitals in China, 76.0%(76/100) patients were male, and the median age was 61 years (21-74 years). More patients had tumors located in the lower rectum (78.0%, 78/100), staged T3-4 (97.0%, 97/100) and N1-2 (93.0%, 93/100), and about half of the tumors invaded the mesorectal fascia (52.0%, 52/100) and with extramural vascular invasion (51.0%, 51/100). Analyses were performed according to the per-protocal (PP) set. All patients in the iTNT group ( n=52) and the TNT group ( n=48) completed SCRT; The 4-cycle chemotherapy±Sintilimab completion rates were 86.5% and 100.0% in the iTNT and TNT groups, respectively. In the iTNT group, 82.7% (43/52), 11.5% (6/52), and 5.8% (3/52) of the patients received 4, 3, and 2 cycles of PD-1 inhibitor. After TNT, 68 patients underwent radical surgery and 15 patients achieved cCR and adopted W&W. The pathological complete response (pCR) rates were 48.5% (16/33) and 17.1% (6/35) in the iTNT and TNT groups, with CR rates of 50.0% (25/50) and 26.1% (12/46), respectively. The incidence of treatment-related grade 3-4 adverse events was 26.9% (14/52, iTNT group) and 18.8% (9/48, TNT group), with thrombocytopenia and leukopenia being the most common. Among patients receiving immunotherapy, grade 3 immunotherapy-related adverse events occurred in 2 (3.8%, 2/52) patients: one case was pancreatitis, another case was hepatitis combined with myositis and myocarditis. Conclusion:The preliminary results show that SCRT-based TNT combined with PD-1 inhibitors could further improve the CR rate for LARC without unexpected serious adverse events.

Objective:To explore the surgical treatment strategies for Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures.Methods:A retrospective analysis was performed on the clinical data of 25 adult patients with Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures, admitted to the Upper Extremity Orthopaedics Department of Zhengzhou Orthopaedic Hospital from June 2013 to June 2023. There were 15 males and 10 females, with an average age of 43.5±14.7 years (range: 20-67 years). Among them, 5 cases were complicated with humeroulnar joint dislocation. The patients were divided into two groups: 17 cases were treated with open reduction and internal fixation (ORIF) of radial head fractures combined with ORIF of proximal ulnar fractures (open reduction group), and 8 cases were treated with radial head replacement combined with ORIF of proximal ulnar fractures (radial head replacement group). At the last follow-up, elbow joint range of motion was recorded, and pain, elbow function, and subjective upper limb function were evaluated using the Visual Analogue Scale (VAS), Mayo Elbow Performance Score (MEPS), and Disabilities of the Arm, Shoulder and Hand (DASH) scale. The incidence of complications was also recorded.Results:All 25 patients were followed up for an average of 25.6±9.0 months (range: 12-45 months). At the last follow-up, the affected elbows in the open reduction group had a flexion of 124.47°±12.59° (range, 90°-140°), extension of 21.12°±10.07° (range, 10°-50°), pronation of 48.59°±11.62° (range, 20°-61°), and supination of 48.53°±8.43° (range, 30°-60°). In the radial head replacement group, the affected elbows showed flexion of 128.75°±13.17° (range, 100°-140°), extension of 14.00°±7.71° (range, 0°-25°), pronation of 61.25°±10.26° (range, 60°-80°), and supination of 71.88°±10.33° (range, 60°-80°). The MEPS score in the open reduction group was 82(75, 85) points (range, 55-90 points), the VAS pain score was 1(1, 2) points (range, 0-3 points), and the DASH score was 9(8, 14) points. In the radial head replacement group, the MEPS score was 90(85, 90) points (range, 85-90 points), the VAS pain score was 1(0, 1) points (range, 0-1 points), and the DASH score was 5(5, 6) points. Complications included 5 cases of heterotopic ossification, 1 case of incision infection, 1 case of nonunion, 1 case of ulnar nerve injury combined with traumatic arthritis, and 1 case of proximal radioulnar bone bridge formation.Conclusions:Both radial head replacement and open reduction internal fixation combined with proximal ulnar fracture fixation can effectively treat Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures. There was no significant difference in postoperative flexion and extension, but the radial head replacement group demonstrated better forearm rotation and DASH scores postoperatively.

Objective:To investigate the prognostic value of aldosterone synthase (CYP11B2) immunohistochemical expression in adrenal specimens for surgical outcomes of primary aldosteronism (PA).Methods:The clinical data of 99 patients who underwent total unilateral adrenalectomy from June 2022 to January 2023 at Beijing Anzhen Hospital was retrospectively analysed. The clinical data of 99 patients who underwent unilateral total adrenalectomy at Beijing Anzhen Hospital from June 2022 to January 2023 were retrospectively analyzed.There were 59 patients in the PA group, age (53.02±10.56) years, body mass index (BMI) (26.28±4.33) kg/m 2, preoperative aldosterone 29.0(15.9, 61.5)ng/dl, plasma renin 1.3(0.6, 2.8)μIU/ml, aldosterone renin ratio (ARR) 19.3(9.1, 59.2) μg/μIU, preoperative potassium (3.60±0.69) mmol/L, and systolic blood pressure (156.54±21.39) mmHg (1 mmHg=0.133 kPa).There were 40 cases in the nonfunctioning adenoma (NFA) group, age (57.23±9.39) years, BMI (27.07±3.46) kg/m 2, preoperative aldosterone 9.0(7.2, 14.1) ng/dl, plasma renin 18.0(5.2, 47.6)μIU/ml, ARR 0.6(0.2, 1.4) μg/μIU, preoperative potassium (4.17±0.41) mmol/L, and systolic blood pressure (157.97±26.87) mmHg. The differences between the two groups were statistically significant for potassium ( P<0.01), aldosterone ( P=0.012), renin ( P<0.01), and ARR ( P<0.01).Surgical outcomes were assessed using the Consensus on the Outcome of Surgery for Primary Aldosteronism (PASO) (complete/partial/no success for clinical and biochemical outcomes). CYP11B2 expression was evaluated by immunohistochemistry using the 2022 World Health Organization's histopathology of primary aldosteronism (HISTALDO) criteria. The correlation between the expression of CYP11B2 and surgical outcomes was assessed. Results:The mean follow-up of 99 patients was (11.73±4.92) months. Of these, 36 out of 59 PA patients had positive CYP11B2 expression in their adrenal specimens, while 23 were negative; all 40 NFA patients were negative for CYP11B2. Among the 36 CYP11B2-positive PA patients, there were 19 cases of aldosterone-producing adenomas, 3 aldosterone-producing nodules, 4 aldosterone-producing micronodules, 8 multiple aldosterone-producing micronodules, and 2 aldosterone-producing diffuse hyperplasia. 36 cases of CYP11B2-positive PA patients had complete clinical success in 15 cases, partial success in 20 cases, and no success in 1 case, and complete biochemical success in 24 cases, partial success in 11 cases, and no success in 1 case; 23 CYP11B2-negative PA patients had complete clinical success in 4 cases, partial success in 15 cases, and no success in 4 cases, and complete biochemical success in 6 cases, partial success in 15 cases, and no success in 2 cases. Adrenal specimens from CYP11B2-positive PA patients had significantly better clinical ( P=0.038) and biochemical ( P=0.008) success rates than CYP11B2-negative PA patients. Patients with aldosterone-producing adenomas had complete clinical success in 8 cases, partial success in 11 cases, and no success in 0 cases, and biochemical success was completely achieved in 16 cases, partially achieved in 2 cases, and not successful in 1 case. They also had significantly higher clinical ( P=0.028) and biochemical ( P<0.01) success rates compared to CYP11B2-negative PA patients. Conclusions:Patients with PA who had immunohistochemical staining for CYP11B2 positivity and high expression in adrenal specimens had a better postoperative clinical and biochemical prognosis. Patients with aldosterone-producing adenomas had the greatest postoperative outcome of all pathological subtypes of PA.

The traditional Chinese medicine(TCM) industry is a crucial part of China's pharmaceutical sector and plays a strategic role in ensuring public health and promoting economic and social development. In response to the practical demand for high-quality development of the TCM industry, this paper focused on the bottlenecks encountered during the digital and intelligent transformation of TCM production systems. Specifically, it explored technical strategies and methodologies for constructing the best TCM production mode. An innovative artificial intelligence(AI)-centered technical architecture for TCM production was proposed, focusing on key aspects of production management including process modeling, state evaluation, and decision optimization. Furthermore, a series of critical technologies were developed to realize the best TCM production mode. Finally, a novel AI-driven TCM production mode characterized by a closed-loop system of "measurement-modeling-decision-execution" was presented through engineering case studies. This study is expected to provide a technological pathway for developing new quality productive forces within the TCM industry.
