Atherosclerosis （AS） is a vascular disease primarily affecting large and medium-sized arteries. It serves as the pathological basis for many cardiovascular and cerebrovascular diseases and is associated with a relatively high incidence of complications and mortality worldwide. Traditional Chinese medicine （TCM） plays an important role in the prevention and treatment of AS， demonstrating unique therapeutic advantages through multiple targets and pathways. Ligusticum chuanxiong， a commonly used Chinese medicine in clinical practice， contains key active components against AS， including ligustrazine， senkyunolide， ligustilide， quercetin， ferulic acid， vanillic acid， chlorogenic acid， gallic acid， protocatechuic acid， caffeic acid， chrysophanol， and β-sitosterol. Recent literature indicates that these active components can regulate AS through multiple mechanisms， including improving endothelial cell dysfunction， alleviating lipid metabolism disorders， inhibiting macrophage foam cell formation， suppressing the invasion， proliferation， and migration of smooth muscle cells， inhibiting apoptosis， exerting anticoagulant effects and inhibiting platelet activation， protecting mitochondrial function， and modulating intestinal flora and its metabolites， demonstrating significant pharmacological activity and clinical potential. Clinically， L. chuanxiong is often combined with Salvia miltiorrhiza， Paeonia lactiflora， Angelica sinensis， and borneol to form compound formulations， enhancing therapeutic effects and achieving synergistic anti-AS activity. Compound treatment with L. chuanxiong primarily focuses on promoting blood circulation and shows significant efficacy for different AS syndrome types. This article provides an in-depth review of the active components， drug pairs， and compound preparations of L. chuanxiong in the prevention and treatment of AS， aiming to lay a foundation for subsequent theoretical research and clinical applications in managing AS and its related complications.

Objective:To investigate the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of BCR::ABL-negative chronic neutrophilic leukemia (CNL) and MDS/MPN with neutrophilia.Methods:This study retrospectively analyzed 12 cases of CNL and MDS/MPN with neutrophilia that underwent allo-HSCT from March 2017 to June 2024, comprising 7 males and 5 females with a median age of 48 ( IQR: 28, 59) years. The 2-year overall survival (OS), disease-free survival (DFS), cumulative incidence of relapse (CIR), and transplantation-related mortality (TRM) rates were analyzed. Complications were also assessed. Results:Of the 12 patients, 6 received matched sibling HSCT and 6 received haploidentical HSCT. All patients had successful engraftment, and the median times of neutrophil and platelet engraftment were 17 ( IQR: 11, 24) days and 15 ( IQR: 9, 28) days, respectively. Grade Ⅱ–Ⅳ acute graft versus host disease (GVHD) and chronic GVHD occurred in 2 and 4 cases, respectively. The 2-year OS, DFS, CIR, and TRM rates were (65.6 ± 16.4) %, (41.7 ± 16.6) %, (47.2 ±18.2) %, and (11.1 ± 11.4) %, respectively, after a median follow-up time of 637 ( IQR: 330, 943) days. One patient died from treatment-related complications due to respiratory failure caused by coronavirus disease 2019. Two patients died due to relapse. Conclusion:Allo-HSCT can be applied as a safe and effective approach to treat CNL and MDS/MPN with neutrophilia.

Objective:To analyze the trabecular bone score (TBS) and its association with muscle health in the postmenopausal population.Methods:It was a cross-sectional study. A total of 214 postmenopausal individuals who underwent dual-energy X-ray absorptiometry testing at the Beijing Research Institute of Sports Science between January and December 2023 were consecutively included. The participants were divided into two groups based on the presence or absence of osteoporosis (OP): 62 cases in the OP group and 152 cases in the non-OP group. All subjects completed body composition assessments and scans of bilateral hip and lumbar spine bone mineral density (BMD)(All the BMD in this study were areal BMD). Demographic data, including age, age at menarche, age at menopause, and fracture history, were also collected. TBS was calculated using the TBS iNsight software. Muscle health indicators included upper limb, lower limb, trunk, and total muscle mass, lean body mass, appendicular skeletal muscle mass index (ASMI), and grip strength. The Pearson correlation analysis was used to determine the relationship between TBS and muscle health indicators, as well as between TBS and the BMD of lumbar spine (L 1-4). Further, multiple linear regression analysis was conducted to explore the independent association between TBS and muscle health indicators. Results:TBS, lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, trunk, whole body in the OP group were all lower than those in the non-OP group [(1.27±0.07) vs (1.35±0.07) score, (36.64±3.45) vs (39.14±3.62) kg, (6.16±0.56) vs (6.44±0.63) kg/m2, (23.87±3.31) vs (25.34±4.33) kg, (3.54±0.47) vs (3.78±0.47) kg, (11.70±1.33) vs (12.68±1.49) kg, (16.57±1.68) vs (17.50±1.69) kg, and (34.91±3.33) vs (37.13±3.47) kg] (all P<0.05). Pearson analysis showed that TBS was positively correlated with lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, whole body (all P<0.05). TBS was negatively correlated with age ( P<0.01). TBS was positively correlated with the BMD of lumbar spine (L 1-4) ( r=0.660, P<0.01). Multiple regression analysis demonstrated that ASMI was positively correlated with TBS ( β=0.284, P<0.01). Conclusion:In the postmenopausal population, individuals with OP have lower TBS. Furthermore, TBS is closely associated with muscle health.

Objective To investigate the role of cytochrome P450 2E1 (CYP2E1) in trichloroethylene (TCE)-induced skin sensitization and liver damage in guinea pigs, using diallyl sulfide (DAS), a CYP2E1 inhibitor, as an intervention. Methods Specific pathogen-free female guinea pigs were randomly divided into blank control group, solvent control group, positive control (2,4-dinitrochlorobenzene) group, TCE-exposure group, and DAS-intervention group. Skin sensitization experiments were conducted using the guinea pig TCE maximal dose-skin sensitization test. Urinary trichloroacetic acid levels were determined following TCE induction and challenge. At 48 hours after the final challenge, serum liver function markers and inflammatory cytokines levels were detected. Histopathological examination on skin and liver tissues was performed, and hepatic CYP2E1 protein expression and oxidative stress indicators were assessed. Results The sensitization rates of guinea pigs were 100.0%, 75.0%, and 33.3% in the positive control, TCE-exposure, and DAS-intervention groups, respectively, while the blank control and solvent control groups were both 0.0%. Compared with the guinea pigs in TCE-exposure group, those in the DAS-intervention group had lower urinary trichloroacetic acid levels at intradermal induction, local induction, first challenge, and 24 hours after the final challenge time point (all P<0.05). Histopathology of guinea pigs showed dermal inflammatory infiltration and basal keratinocyte necrosis in the TCE-exposure group, whereas only mild dermal inflammation was observed in the DAS-intervention group. The guinea pigs in TCE-exposure group exhibited diffuse hepatocellular necrosis, while hepatic damage in the DAS-intervention group was alleviated, characterized by only mild hepatocellular steatosis and hepatocyte swelling around the central vein. The skin sensitization rate of guinea pigs in the TCE-exposure group increased (all P<0.01), the serum alanine aminotransferase (ALT )activity, the levels of interleukin (IL)-2, IL-17, and tumor necrosis factor-α (TNF- α) increased (all P<0.05), the relative expression of CYP2E1 protein, the activity of superoxide dismutase (SOD), and the level of malondialdehyde in liver tissue increased (all P<0.05), while the activity of catalase decreased (P<0.05), compared with the blank control and solvent control groups. The serum ALT activity and the levels of IL-2, IL-17, and TNF-α of guinea pigs in DAS-intervention group reduced (all P<0.05), as well as CYP2E1 protein expression, SOD activity, and malondialdehyde level in liver tissue reduced (all P<0.05), compared with the TCE-exposure group. Conclusion TCE can induce hepatic CYP2E1 expression, thereby promoting oxidative stress and inflammatory responses, which contributes to skin sensitization and liver damage. DAS alleviates TCE-induced toxic effects on skin and liver by inhibiting CYP2E1 expression.

The general situation of patients (age, gender, comorbid diseases, etc.), the medication of esketamine hydrochloride nasal spray, the combined use of antidepressants, the time from medication to the occurrence of dissociative symptoms each time, duration, severity, evaluation results of causal relationship with esketamine application, intervention and prognosis were recorded, and a retrospective descriptive statistical analysis was performed.Results:A total of 21 patients with TRD were enrolled in the study, including 17 (81.0%) with dissociative symptoms, 10 males and 7 females; the age ranged from 20 to 53 years, with a median age of 36 years. All patients were treated with esketamine hydrochloride by nasal spray. The first dose was 56 mg, and the other seven doses were 56 mg or 84 mg, twice a week, lasting for 4 weeks. The 17 patients were all given combination treatment with oral antidepressants. A total of 88 times of dissociative symptoms occurred in the 17 patients. The time from medication to the onset of dissociative symptoms ranged from 4 to 128 min, with a median time of 15 min. The duration of dissociative symptoms ranged from 12 to 326 minutes, with a median time of 70 minutes. The dissociative symptoms were mostly mild. The causal relationship analysis between the esketamine hydrochloride nasal spray and the dissociative symptoms showed that it was definitely related in 6 cases, probably in 1 case, and possibly in 10 cases. The dissociative symptoms in all patients were subsided without intervention.Conclusions:Esketamine hydrochloride nasal spray can cause dissociative symptoms in patients with TRD, most of which occur within 30 minutes after the treatment. The duration of symptoms in most patients is less than 120 minutes, most of which are mild and can subside on their own, and the prognosis is good.
