Background: Sex-based differences often influence the therapeutic efficacy and safety of medications. Semen Cuscutae is a traditional tonic botanical drug with sex-specific characteristics, traditionally indicated for conditions such as impotence (exclusive to males) and restless fetus (exclusive to pregnant females). However, most existing studies have focused on a single sex. Objective: To evaluate the sex-specific biological effects of Semen Cuscutae in rats and explore its molecular mechanisms, with the aim of uncovering its pharmacological characteristics through a multiomics approach. Methods: A traditional aqueous extract of Semen Cuscutae (SCA) was used as the experimental material. Forty adult Sprague-Dawley rats (equal numbers of males and females) were randomly divided into 4 groups: male control, male SCA treatment (240 mg/kg), female control, and female SCA treatment (240 mg/kg), with 10 rats in each group. The biological effects were comprehensively evaluated using a combination of open field test, biochemical analyses, proteomics, and gut microbiota profiling. Results: As a tonic botanical drug, SCA appeared to directly affect the mental and behavioral state of rats. It significantly altered the time spent by rats in the center area during the open field test, showing a sex-dependent reversal of behaviors. Proteomic analysis of brain tissue identified 624 differentially expressed proteins across the groups, with 10 key differentially expressed proteins related to sex differences, including fibroblast growth factor receptor 3, transcription elongation factor A protein-like 1, 40S ribosomal protein S25, neural cell adhesion molecule, and anion exchange protein 2 (SLC4A2). Enrichment analysis revealed that in male rats, SCA upregulated proteins involved in biological processes such as ribosome function and energy derivation, supporting protein synthesis and enhancing energy supply, showing an overall gain effect. In contrast, in female rats, SCA downregulated proteins associated with processes such as positive regulation of target of rapamycin (TOR) signaling and vesicle transport, suggesting suppression of neuronal signaling and material transport, indicative of a shift toward a more restrained physiological state. Furthermore, SCA reduced gut microbiota diversity in female rats but increased it in males, including the abundance of Akkermansia, which may serve as a crucial mediator. Conclusion: Overall, the biological effects of SCA differ significantly between male and female rats, with evidence suggesting greater health benefits in males. These findings help elucidate the scientific basis of its traditional applications and provide guidance for the precise application of SCA as a functional health food.

Background: Salvia miltiorrhiza Bunge, commonly known as “Danshen” in China due to the distinctive red color of its roots, is one of the most widely used traditional Chinese medicines. It is cultivated in various regions across China, and environmental differences among these regions can affect the secondary metabolites of plants, thereby influencing the quality of S. miltiorrhiza. In recent years, increasing demand for S. miltiorrhiza has exacerbated the problem of origin fraud. Therefore, ensuring the authenticity of its geographical origin is crucial for the sustainable development of the industry. Objective: The red coloration of S. miltiorrhiza is closely associated with the content of its primary active compounds, particularly tanshinones. Therefore, both its internal chemical composition and external color characteristics serve as key indicators for quality assessment. This study utilized hyperspectral imaging technology to evaluate its potential in classifying the geographical origin of S. miltiorrhiza. Methods: Spectral data reflecting the internal chemical properties of S. miltiorrhiza were integrated with color information representing its external features through 3 levels of data fusion. These fused datasets were then combined with deep learning algorithms to achieve accurate origin classification. Results: The results demonstrated that the Transformer model combined with soft-voting decision-level fusion achieved the highest classification accuracy of 98.72% by integrating image color and short-wave infrared spectral data. Conclusion: This study demonstrates that integrating hyperspectral imaging spectral data with color information provides a reliable and innovative approach for verifying the authenticity and traceability of S. miltiorrhiza.

Objective:To evaluate the effect of ultrasound-guided adductor canal block with bupivacaine liposome on analgesia in elderly patients undergoing total knee arthroplasty.Methods:This was a prospective study. Sixty American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, regardless of gender, aged 65-83 yr, weighing 50-80 kg, scheduled for elective unilateral total knee arthroplasty under subarachnoid anesthesia from April 2023 to January 2024 in Zhengzhou Orthopaedic Hospital, were divided into 2 groups ( n=30 each) using a random number table method: bupivacaine liposome group (LB group) and ropivacaine group (R group). Ultrasound-guided adductor canal block was performed at 30 min before subarachnoid anesthesia, bupivacaine liposome diluent 20 ml (133 mg) was injected in LB group, and 0.5% ropivacaine 20 ml was injected in R group. Patient-controlled intravenous analgesia was performed after operation, and tramadol was used for rescue analgesia when the visual analogue scale (VAS) score ≥3. VAS scores at rest and during activity were recorded at 8, 12, 24, 48 and 72 h after surgery. The time to the first pressing analgesia pump and rescue analgesia were recorded within 72 h after surgery. The quadriceps muscle strength was measured at 1 day before surgery and 12, 24, 48 and 72 h after surgery. The knee joint range of motion was assessed at 1 day before surgery and 24, 48 and 72 h after surgery. Patient′s satisfaction with analgesia was recorded at 72 h after surgery. The adverse reactions within 72 h after surgery were also recorded. Results:Compared with R group, VAS scores at rest and during activity were significantly decreased at 12, 24, 48 and 72 h after surgery, the time to the first pressing analgesia pump was prolonged, the rate of rescue analgesia after surgery was decreased, the score for the patient′s satisfaction with analgesia was increased, the knee joint range of motion was increased ( P<0.05), and no significant change was found in the quadriceps muscle strength and incidence of adverse reactions in LB group ( P>0.05). Conclusions:Ultrasound-guided adductor canal block with bupivacaine liposome provides better analgesia than ropivacaine in elderly patients undergoing total knee arthroplasty.

Objective:To explore any effect of transcranial magnetic stimulation and peripheral magnetic stimulation of the mylohyoid muscle on dysphagia among stroke survivors.Methods:Sixty stroke survivors with dysphagia were randomly divided into a control group, a peripheral magnetic stimulation group, a central magnetic stimulation group, and a central + peripheral magnetic stimulation group, each of 15. In addition to routine swallowing training, the subjects were given the appropriate magnetic stimulation daily, five times a week for two weeks. Before and after the intervention, swallowing was evaluated using the Functional Oral Intake Scale (FOIS), Penetration-Aspiration Scale (PAS) and a functional dysphagia scale (FDS).Results:The average FDS, PAS, and FOIS scores of all four groups had improved significantly after the treatment. Improvement significantly greater than in the control group was observed in the average FOIS, FDS and PAS scores of the other three groups. The peripheral + central magnetic stimulation group showed the greatest average improvement.Conclusion:Combining mylohyoid muscle magnetic stimulation with magnetic stimulation of the cerebral cortex can significantly relieve dysphagia. It is more effective than conventional swallowing rehabilitation or either magnetic stimulation alone.

Objective To investigate the relationship between the volume of left atrial appendage and recurrence of atrial fibrillation(AF)after radiofrequency ablation. Methods In this retrospective cohort study, 66 cases of first atrial fibrillation radiofrequency catheter ablation in the Department of cardiovascular medicine of the First Affiliated Hospital of Zhengzhou University were enrolled from June 2014 to June 2016 and divided into the recurrence group(n=18)and the non recurrent group(n=48)based on the 1 year follow-up results ,Collecting the patient's clinical data and following up.64 layers of spiral CT scans were performed for all patients before operation,and the volume of left atrium( LAV)and left atrial appendage volume(LAAV)were measured. The general data ,laboratory examinationresults ,echocardiographic parameters and left atrial CT parameters of two groups were compared. The relationship between patient parameters and recurrence of atrial fibrillation after radio-frequency ablation were analyzed by multivariate logistic regression analysis. Results There was no significant difference in blood lipid and left ventricular ejection fraction(LVEF%)between the two groups in terms of sex, age ,hypertension ,coronary heart disease and other common diseases (P > 0.05).The volume of left atrial appendage and left atrial volume in the recurrent group were larger than those in the non recurrence group (P <0.05). The left atrial appendage volume(OR=1.518,95%CI:1.151-2.000,P = 0.003)can be used as an independent risk factor for postoperative recurrence of atrial fibrillation. The area under the ROC curve of left atrial appendage volume in predicting the recurrence of atrial fibrillation after radiofrequency ablation is 0.806(95%CI:0.689-0.922 ,P < 0.001). Conclusion Greater left ventricular volume is an independent risk factor for recurrence of atrial fibrillation after radiofrequency catheter ablation ,whether in paroxysmal atrial fibrillation or persistent atrial fibrillation.
