ObjectiveTo explore the mechanism of action of Cuscutae Semen-Salviae Miltiorrhizae Radix et Rhizoma in the treatment of recurrent spontaneous abortion （RSA） through network pharmacology， molecular docking， and cell experiment verification. MethodsThe Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and UniPort databases were used to screen and organize the active ingredients and corresponding targets of Cuscutae Semen-Salviae Miltiorrhizae Radix et Rhizoma. The potential therapeutic targets of RSA were screened in Online Mendelian Inheritance in Man （OMIM）， GeneCards database， DrugBank database， DisGeNET database， and Therapeutic Target Database （TTD）. The potential core targets of Cuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma for treating RSA were further screened by constructing a protein-protein interaction （PPI） network and topological analysis. Meanwhile， the Database for Annotation， Visualization and Integrated Discovery （DAVID） was chosen to perform enrichment analysis on intersection targets. On this basis， AutoDock software was used for molecular docking， and the data were imported into PyMOL software for visualization and composition. Finally， the cell counting kit-8 （CCK-8） experiment， Transwell cell invasion assay， and Western blot were used to detect the effects of serum containing Cuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma on HTR-8/SVneo cells and observe the effects on the interleukin （IL）-6/signal transducer and activator of transcription 3（STAT3） signaling pathway and related proteins. ResultsThrough network pharmacology analysis， a total of 69 active ingredients， 73 potential therapeutic targets， and 17 core targets， including IL-6， IL-10， and STAT3， were collected. The 73 common targets were enriched in 614 Gene Ontology （GO） entries and 57 Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathways. The molecular docking results indicated that IL-6 and STAT3 had good binding ability with the main active ingredients， including matrine， cryptotanshinone， and tanshinone Ⅱ_A. The cell experiment results showed that， compared with those of the control group， after 24 hours of treatment with the drug-containing serum， the survival and invasion rates of HTR-8/SVneo cells were significantly increased （P<0.05）， and the expression of IL-6/STAT3 signaling pathway and related proteins IL-10 and c-Myc was significantly elevated （P<0.05）. Moreover， the trend of action in the drug-containing serum group was consistent with that of pathway agonists. ConclusionCuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma may enhance the survival rate and invasive activity of HTR-8/SVneo cells to further prevent and treat RSA by activating the IL-6/STAT3 signaling pathway and upregulating the expression of downstream factors IL-10 and c-Myc in the pathway.

Since the first successful transcatheter aortic valve replacement (TAVR) was performed globally in 2002, the TAVR technology has become increasingly mature. With more than a decade of development in China, its application experience, device research and development, procedural improvements, evidence-based medicine, and guideline updates have continuously progressed, leading to a significant increase in the number of procedures conducted. Compared to traditional surgical operations, TAVR has different postoperative monitoring points and principles for the prevention and management of complications, necessitating the formulation of corresponding monitoring and treatment protocols that align with the technical characteristics of the procedure. This guideline is based on clinical practice and incorporates both domestic and international literature as well as the experiences of Fuwai Hospital. It distills and organizes routine postoperative monitoring practices, process optimization, and complication management for TAVR, establishing a set of practical guidelines for postoperative monitoring in China. These guidelines have strong practical value for optimizing postoperative management strategies and preventing and managing complications, which is beneficial for early functional recovery of patients, shortening hospital stays, and reducing complication rates. They provide guidance and reference for domestic peers and support the standardized development and quality improvement of postoperative management for TAVR in China.

Objective　To understand the current infection status and genotype of Echinococcus multilocularis in small rodents in southern Xinjiang, and to provide a theoretical basis for the formulation of local prevention and control measures. Methods In 2023, small rodents were captured and necropsied in Wuqia County, Atushi City, and Hejing County, Xinjiang. DNA was extracted from diseased organs, Cox1 and Nad2 genes were amplified by PCR and sequenced, and MEGA software constructed the phylogenetic tree. Dnasp analyzed the genotype genetic polymorphism of the isolates, and NetWork10 was used to draw the gene haplotype network. Results　A total of 1 541 small rodents were captured in three counties (cities), with common voles (Microtus arvalis)(53.01%) and Apodemus sylvaticus (28.1%) being predominant. After necropsy and PCR identification, 13 small rodents were found to be infected with Echinococcus multilocularis, with an overall infection rate of 0.84% (13/1 541). Among them, 11 were common voles, with an infection rate of 1.35% (11/817), and 2 were Apodemus sylvaticus, with an infection rate of 0.46% (2/433). There was no significant difference in the infection rate of echinococcosis between voles and Apodemus sylvaticus (χ2=2.15, P>0.05). The infection rates of Echinococcus multilocularis in small rodents in Hejing County, Atushi City, and Wuqia County were 1.40% (7/500), 1.15% (6/527), and 0, respectively (χ2=6.77, P<0.05). The results of the phylogenetic tree showed that 13 isolates belonged to the Asian type. The results of DNA polymorphism analysis showed that the haplotype diversity of Cox1 gene sequence was Hd=0.834±0.054, with a low nucleotide diversity of Pi=0.004 60±0.000 87; for Nad2 gene, haplotype diversity was Hd=0.758±0.076, and nucleotide diversity was Pi=0.005 99±0.001 59, indicating high haplotype diversity and low nucleotide diversity for both Cox1 and Nad2 genes. The haplotype network diagram showed that the 13 Cox1 gene sequences were dominated by H1 haplotype, with H2, H3, Sichuan (AB477012), Xinjiang (MH259773), and Kazakhstan (AB461415) distributed in a scattered manner and connected to it. The 13 Nad2 gene sequences were classified as H1 haplotype along with those from Xinjiang (OP628494), Japan (OP628493), and Kazakhstan (AB461406). Conclusions　Echinococcus multilocularis infections exist in small rodents in Hejing County and Atushi City in southern Xinjiang. The common vole and Apodemus sylvaticus can be used as the dominant intermediate hosts of local Echinococcus multilocularis in the region. There are genetic variations in the Cox1 and Nad2 genes, with the genotypes of all 13 isolates being Asian genotype, and haplotype predominantly H1.

Allergic rhinitis （AR） is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine （TCM） employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment， demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies （such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction， Yiqi tuomin decoction）， external therapies （including intradermal needles， acupoint application， tuina， and herbal nasal therapy）， as well as combined internal and external approaches （oral herbs combined with acupoint application）， have demonstrated significant effects in alleviating clinical symptoms， improving immune indicators， and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase， thereby modulating immune balance， suppressing inflammatory responses， inhibiting pyroptosis， reducing mucus secretion， and promoting nasal mucosal repair.

Objective To analyze the lung function condition and the prevalence of pulmonary ventilation disorders in the occupational population of Wuhan, and to explore their influencing factors. Methods Physical examination data from the Wuhan Prevention and Treatment Center for Occupational Diseases were used in this study, and finally 9499 people were selected as the study subjects. The linear regression model and logistic regression model were used to analyze the influencing factors of pulmonary ventilation function and pulmonary dysfunction. The restricted cubic spline was used to explore the nonlinear relationship. Results The prevalence of pulmonary ventilation disorders was 1.7%, and the lung function indexes FVC, FEV1, and FEV1/FVC were significantly lower in the population aged >27 years than in the population aged <27 years (P<0.001). The lung function indexes FVC and FEV1 were significantly lower in females than in males (P<0.001). The lung function indexes FVC and FEV1 were significantly lower in underweight occupational groups than in normal-weight groups (P<0.001), and FVC and FEV1 were significantly lower in dust-exposed occupational groups than in groups without dust exposure(P<0.05). Restricted cubic spline plots showed a nonlinear relationship between age and lung function indexes FVC and FEV1 (P_nonlinear< 0.05). Age and BMI were the risk factors for pulmonary ventilation disorders. Conclusion Age, gender, BMI, and dust exposure are risk factors for decreased FVC and FEV1. Age is the risk factor for decreased FEV1/FVC. Age and BMI are the risk factors for pulmonary ventilation disorders.

Objective To investigate the clinical effects of different right lung volume reduction techniques when the donor lung is oversized and mismatched with the recipient. Methods Clinical data of 10 recipients who underwent right lung volume reduction lung transplantation at the First Affiliated Hospital of Xi'an Jiaotong University from October 2022 to June 2024 were collected, including gender, age, primary disease type, and type of transplantation. A retrospective analysis was performed on postoperative complications within 90 days, duration of mechanical ventilation, hospital stay, and survival status to explore the impact of different volume reduction techniques on the survival rate of lung transplant recipients. Results A total of 10 right lung volume reduction recipients were included in this study, with 2 cases of upper lobe reduction, 7 cases of middle lobe reduction, and 1 case of lower lobe reduction. Three recipients developed airway complications (one each with upper, middle, and lower lobe reduction). The 30-day survival rate was 90% and the 1-year survival rate was 70%. One recipient with upper lobe reduction died of septic shock during the perioperative period, one with lower lobe reduction died of airway anastomotic fistula 2 months after surgery, and one with middle lobe reduction died of renal insufficiency 1 year after surgery. All 7 recipients with middle lobe reduction successfully passed the perioperative period, with one case of airway anastomotic stenosis (1/7). The average duration of mechanical ventilation was 71 hours, and the average hospital stay was 26 days. The 30-day survival rate was 7/7, and the 1-year survival rate was 6/7. Conclusions Middle lobe reduction in right lung transplantation surgery has the advantages of low incidence of airway complications, good safety, and minimal loss of lung function, and may be a better right lung volume reduction option with potential for application.

OBJECTIVE: To observe the clinical efficacy of warming acupuncture combined with western medication for oligoasthenoteratozoospermia of kidney-yang insufficiency and its effects on the levels of interleukin (IL)-6 and IL-10 in seminal plasma. METHODS: A total of 60 patients with oligoasthenoteratozoospermia of kidney-yang insufficiency were randomly divided into a combination group and a medication group, with 30 cases in each group. The medication group was treated with levocarnitine oral solution orally, 10 mL once, 3 times a day. On the basis of the treatment in the medication group, warming acupuncture was applied at Baihui (GV20), Guanyuan (CV4) and Mingmen (GV4) in the combination group, once every other day, 3 times a week. Both groups were treated for 12 weeks. Before and after treatment, the TCM syndrome score was observed, the semen routine indexes (the sperm concentration, progressive [PR] sperm motility, PR + non-progressive [NP] sperm motility and sperm malformation rate), the serum sex hormones indexes (follicle-stimulating hormone [FSH], luteinizing hormone [LH], testosterone [T] and estradiol [E₂]), as well as the IL-6 and IL-10 levels in seminal plasma were detected, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, except for the hyposexuality score in the medication group, the each item scores and total scores of TCM syndrome were decreased compared with those before treatment (P<0.01, P<0.05), the sperm malformation rates, serum FSH and LH levels, IL-6 levels in the seminal plasma were decreased compared with those before treatment (P<0.01, P<0.05), the PR sperm motility, PR + NP sperm motility, serum T levels, IL-10 levels in the seminal plasma were increased compared with those before treatment (P<0.01, P<0.05) in the two groups; the sperm concentration was increased compared with that before treatment in the combination group (P<0.01). After treatment, compared with the medication group, except for the hyposexuality and frequent nocturia scores, the each item scores and total score of TCM syndrome were lower (P<0.01, P<0.05); the sperm concentration, PR sperm motility and PR + NP sperm motility, serum T level, IL-10 level in the seminal plasma were higher (P<0.01, P<0.05); sperm malformation rate, serum FSH and LH levels, IL-6 level in the seminal plasma were lower (P<0.01, P<0.05) in the combination group. The total effective rate was 83.8% (25/30) in the combination group, which was superior to 60.0% (18/30) in the medication group (P<0.05). CONCLUSION Warming acupuncture combined with western medication can effectively treat oligoasthenoteratozoospermia of kidney-yang insufficiency, regulate the levels of sex hormones, and its mechanism may be related to the down-regulation of IL-6 level and the up-regulation of IL-10 level in seminal plasma.

BACKGROUND: Diabetic foot is a complex condition with high incidence, recurrence, mortality, and disability rates. Current treatments for diabetic foot ulcers are often insufficient. This study was conducted to identify potential therapeutic targets for diabetic foot. METHODS: Datasets related to diabetic foot and diabetic skin were retrieved from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified using R software. Enrichment analysis was conducted to screen for critical gene functions and pathways. A protein interaction network was constructed to identify node genes corresponding to key proteins. The DEGs and node genes were overlapped to pinpoint target genes. Plasma and chronic ulcer samples from diabetic and non-diabetic individuals were collected. Western blotting, immunohistochemistry, and enzyme-linked immunosorbent assays were performed to verify the S100 calcium binding protein A9 (S100A9), inflammatory cytokine, and related pathway protein levels. Hematoxylin and eosin staining was used to measure epidermal layer thickness. RESULTS: In total, 283 common DEGs and 42 node genes in diabetic foot ulcers were identified. Forty-three genes were differentially expressed in the skin of diabetic and non-diabetic individuals. The overlapping of the most significant DEGs and node genes led to the identification of S100A9 as a target gene. The S100A9 level was significantly higher in diabetic than in non-diabetic plasma (178.40 ± 44.65 ng/mL vs. 40.84 ± 18.86 ng/mL) and in chronic ulcers, and the wound healing time correlated positively with the plasma S100A9 level. The levels of inflammatory cytokines (tumor necrosis factor-α, interleukin [IL]-1, and IL-6) and related pathway proteins (phospho-extracellular signal regulated kinase [ERK], phospho-p38, phospho-p65, and p-protein kinase B [Akt]) were also elevated. The epidermal layer was notably thinner in chronic diabetic ulcers than in non-diabetic skin (24.17 ± 25.60 μm vs. 412.00 ± 181.60 μm). CONCLUSIONS S100A9 was significantly upregulated in diabetic foot and was associated with prolonged wound healing. S100A9 may impair diabetic wound healing by disrupting local inflammatory responses and skin re-epithelialization.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.
