With the advancement in big data and artificial intelligence technologies, the extensive application of omics technologies in traditional Chinese medicine(TCM) research has generated large experimental datasets, enabling the exploration of cross-scale correlations among massive data and thereby resulting in the shift toward a data-intensive research paradigm. The emerging approach of multi-omics data fusion analysis, emphasizing technical and computational tools, presents a potential breakthrough in this field. The holistic perspective of TCM aligns with the concept of multi-omics data fusion, yet the data types encountered exhibit high dimensionality with small sample sizes, necessitating data processing techniques such as dimensionality reduction. The current challenge lies in selecting suitable analytical methods for these data to enhance the systematic understanding of physiological functions and disease diagnosis/treatment processes. This paper explores the theories and frameworks of multi-omics data fusion, analyzes methods for fusing high-dimensional, small-sample multi-omics data in TCM, and aims to provide insights for advancing TCM research.

OBJECTIVE: To investigate the effect of autologous osteochondral tissue and periosteum transplantation on tendon-bone healing of rotator cuff in rabbits. METHODS: Twenty-four male New Zealand white rabbits were randomly divided into autologous osteochondral tissue and periosteum transplantation group (experimental group, n=12) and simple suture group (control group, n=12). Both groups were subjected to acute supraspinatus tendon injury and repaired with corresponding techniques. At 4, 8, and 12 weeks after operation, 4 specimens from each group were taken from the right shoulder joint for histological examination (HE staining, Masson staining, and Safranin O-fast green staining), and the left shoulder was subjected to biomechanical tests (maximum tensile load and stiffness). RESULTS: Both groups of animals survived until the completion of the experiment after operation. At 4 weeks after operation, both groups showed less collagen fibers and disorder at the tendon-bone junction. At 8 weeks, both groups showed reduced inflammation at the tendon-bone junction, with more organized and denser collagen fibers and chondrocytes. The experimental group showed better results than the control group. At 12 weeks, the experimental group showed typical tendon-bone transition structure, with increased generation of collagen fibers and chondrocytes, and the larger cartilage staining area. Both groups showed an increase in maximum tensile load and stiffness over time ( P<0.05). The stiffness at 4 weeks and the maximum tensile load at 4, 8, and 12 weeks in the experimental group were superior to control group, and the differences were significant ( P<0.05). There was no significant difference in stiffness at 8, 12 weeks between the two groups ( P>0.05). CONCLUSION Autologous osteochondral tissue and periosteum transplantation can effectively promote the fiber and cartilage regeneration at the tendon-bone junction of rotator cuff and improve the biomechanical effect of shoulder joint in rabbits.

A previous study showed that the length of the foreskin plays a role in the risk of sexually transmitted infections and chronic prostatitis, which can lead to poor quality of sexual life. Here, the association between foreskin length and sexual dysfunction was evaluated. A total of 5700 participants were recruited from the andrology clinic at The First Affiliated Hospital of University of Science and Technology of China (Hefei, China). Clinical characteristics, including foreskin length, were collected, and sexual function was assessed by the International Index of Erectile Function-5 (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires. Men with sexual dysfunction were more likely to have redundant foreskin than men without sexual dysfunction. Among the 2721 erectile dysfunction (ED) patients and 1064 premature ejaculation (PE) patients, 301 (11.1%) ED patients and 135 (12.7%) PE patients had redundant foreskin, respectively. Men in the PE group were more likely to have redundant foreskin than men in the non-PE group ( P = 0.004). Logistic regression analyses revealed that the presence of redundant foreskin was associated with increased odds of moderate/severe ED (adjusted odds ratio [aOR] = 1.31, adjusted P = 0.04), moderate PE (aOR = 1.38, adjusted P = 0.02), and probable PE (aOR = 1.37, adjusted P = 0.03) after adjusting for confounding variables. Our study revealed a positive correlation between the presence of redundant foreskin and the risk of sexual dysfunction, especially in PE patients. Assessment of the length of the foreskin during routine clinical diagnosis may provide information for patients with sexual dysfunction.

The anterior cingulate cortex (ACC) has recently been proposed as a key player in the representation of itch stimuli. However, to date, little is known about the contribution of specific ACC interneuron populations to itch processing. Using c-Fos immunolabeling and in vivo Ca²⁺ imaging, we reported that both histamine and chloroquine stimuli-induced acute itch caused a marked enhancement of vasoactive intestinal peptide (VIP)-expressing interneuron activity in the ACC. Behavioral data indicated that optogenetic and chemogenetic activation of these neurons reduced scratching responses related to histaminergic and non-histaminergic acute itch. Similar neural activity and modulatory role of these neurons were seen in mice with chronic itch induced by contact dermatitis. Together, this study highlights the importance of ACC VIP⁺ neurons in modulating itch-related affect and behavior, which may help us to develop novel mechanism-based strategies to treat refractory chronic itch in the clinic.

Objective:To review the literature on improving patients′medical experience, analyze the current research status in this field, and provide references for enhancing patients′medical experience.Methods:A search was conducted for studies related to improving patients′medical experience published from January 2015 to November 2024 in eight databases, including CNKI and Web of Science. Using software CiteSpace 6.4.R1 and VOSviewer 1.6.19 to analyze publication trends, keyword clustering, existing problems in the process of improving patients′medical experience, and the measures taken.Results:6 507 articles were included, of which 4 452 were in English (68.4%) and 2 055 were in Chinese (31.6%). The annual number of publications showed a nearly linear growth trend ( R2 = 0.983 9). The clustering analysis results indicated that domestic and international research mainly focused on patient-centered diagnostic and treatment systems, behaviors, services, and environments. Existing studies revealed that there were still problems such as long waiting times for appointments and consultations (292 articles), uneven distribution of medical resources (198 articles), and poor doctor-patient communication (155 articles). To improve patients′medical experience, the following intervention measures were proposed: accelerating the medical reform process and strengthening government responsibilities (169 articles); enhancing service concepts and innovating service models (363 articles); optimizing the consultation process and simplifying medical procedures (221 articles); improving the consultation environment and optimizing the facilities in the consultation area (181 articles); and integrating technological advantages to cover the entire medical process (346 articles). Conclusions:Research on improving patients' medical experience was increasingly attracting the attention of more and more scholars. Issues such as low service efficiency, unbalanced resource allocation, and poor doctor-patient communication need to be given special attention. In the future, it is recommended to enhance the experience of patients′ medical experience by strengthening policy and institutional guarantees, accelerating the construction of information technology, improving doctor-patient communication skills and humanistic care, and enhancing the capacity of primary medical services.

Objective:To compare the arthroscopic autologous osteochondral transfer (AOT) and arthroscopic subscapularis augmentation (ASA) in the treatment of recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20%.Methods:A retrospective analysis was conducted of the clinical data of 42 patients who had been treated at Department of Orthopaedics, The Second Hospital of Lanzhou University for recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20% from January 2022 to January 2023. There were 30 males and 12 females, with an age of (32.2±15.2) years. Altogether 12 left shoulders and 30 right shoulders were affected. The patients were divided into 2 groups according to their surgical methods: an AOT group in which 15 cases were treated with AOT and an ASA group in which 27 cases treated with ASA. The Rowe score, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS), and shoulder range of motion were compared between groups at the last follow-up. All the above indexes were compared between pre-surgery and post-surgery in each group. The incidence of complications in the 2 groups was recorded.Results:There were no statistically significant differences in the preoperative general data between the 2 groups, indicating comparability ( P > 0.05). A total of 42 patients were followed up for (17.2±5.9) months after surgery. At the last follow-up, in the ASA group and the AOT group respectively, the Rowe score was (97.0±4.4) points and (98.3±2.4) points, the ASES score (97.9±5.2) points and (99.1±3.7) points, and the VAS score 0 (0, 0) point and 0 (0, 1) point, showing no significant difference between the 2 groups ( P > 0.05). The above items in the 2 groups were significantly improved compared with those before surgery ( P < 0.05). At the last follow-up, in ASA group and AOT group respectively, shoulder abduction was 169.2°±3.0° and 168.3°±3.1°, and flexion 171.9°±4.0° and 173.3°±4.1°, showing no significant difference between the 2 groups ( P > 0.05); the abduction 90° external rotation was 67.3°±3.2° in the AOT group, significantly better than that in the ASA group (64.4°±3.5°) ( P < 0.05). The above items in the 2 groups were significantly improved compared with those before operation ( P < 0.05). Follow-ups revealed no infection or osteoarthritis. After surgery, 1 case of shoulder re-dislocation and 6 cases of shoulder pain occurred in the ASA group, while no cases of shoulder re-dislocation or shoulder pain occurred in the AOT group. There was no significant difference between the 2 groups in the incidence of complications ( P > 0.05). Conclusions:In the treatment of patients with recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20%, both AOT and ASA can improve shoulder function, but AOT is superior to ASA in 90° external rotation.

Objective:To investigate the correlation between non-Hodgkin lymphoma (NHL) and chronic hepatitis B virus (HBV) infection by using the method of two-sample bidirectional Mendelian randomization (MR) analysis.Methods:Genetic variation data for NHL came from the Finnish database (FinnGen) Consortium 2021 public genome-wide association study (GWAS) dataset including 1 088 patients with NHL and 299 952 control subjects. The GWAS dataset for chronic HBV infection was derived from GWAS analysis published in 2021, including 145 NHL patients and 351 740 control subjects. NHL was used as an exposure factor, single nucleotide polymorphism (SNP) significantly associated with NHL was used as an instrumental variable (IV), chronic HBV infection was used as an outcome variable. The two-sample MR analysis was performed by using inverse-variance weighted (IVW) method. Chronic HBV infection was taken as an exposure factor, SNP significantly associated with chronic HBV infection was taken as IV, and NHL was taken as outcome variable, and then reverse two-sample MR analysis was performed. The IVW method used the inverse variance of each IV as the weight to fit, and the ratio method was used to measure SNP one by one and make weighted regression analysis, so as to obtain the overall estimate. MR-Egger regression and the weighted median (WME) method were also used to supplement the IVW method. In sensitivity analysis, leave-one-out sensitivity analysis was used to evaluate the impact of a single SNP. Cochran Q test was used to analyze the heterogeneity of the selected IV. MR-Egger regression was used to measure the average horizontal pleiotropy of IV, and the P-value of directivity was calculated. The MR-pleiotropy residual sum and outlier (MR-PRESSO) Global Test was used to exclude possible horizontal pleiotropic outliers and reduce bias. Results:In the leave-one-out sensitivity analysis, SNP with significant effects on causal associations was excluded. In forward MR analysis, IVs were 10 SNPs associated with NHL; the IVW method indicated that there was no causal association between NHL and chronic HBV infection ( OR = 0.979, 95% CI: 0.925-1.036, P = 0.465). MR-Egger regression ( OR = 0.992, 95% CI: 0.926-1.062, P = 0.825) and WME method ( OR = 0.992, 95% CI: 0.934-1.055, P = 0.805) were used as supplementary methods to obtain the consistent results. In sensitivity analysis, Cochran Q test showed no heterogeneity among IVs (IVW method: P = 0.271, MR-Egger regression: P = 0.239). Horizontal pleiotropy was not found in the MR-Egger regression (intercept was -0.01, P = 0.778) and the MR-PRESSO Global Test ( P > 0.05), suggesting robust results. In the reverse MR analysis, IVs were 8 SNPs associated with NHL; the IVW method ( OR = 1.117, 95% CI: 0.942-1.324, P = 0.202) also found no significant causal relationship between chronic HBV infection and NHL; MR-Egger regression ( OR = 0.777, 95% CI: 0.450-1.343, P = 0.401) and WME method ( OR = 1.120, 95% CI: 0.887-1.415, P = 0.351) also showed similar risk estimates. Sensitivity analysis also suggested the consistency and reliability of the results. Cochran Q test showed no heterogeneity among IVs (IVW method: P = 0.775, MR-Egger regression: P = 0.903). Horizontal pleiotropy was not found by MR-Egger regression (intercept was 0.102, P = 0.548) and MR-PRESSO Global Test ( P > 0.05). Conclusions:MR analysis suggests no causal relationship between NHL and chronic HBV infection.

Objective To investigate the efficacy and safety of regional citrate anticoagulation(RCA)in continuous blood purification(CBP)treatment during the shock and infection phases of severe burns.Methods A retrospective analysis was conducted on the clinical data of 64 patients who received RCA-CBP treatment at the Burns Reseaich Institute,the First Affiliated Hospital of Army Medical University from Jan-uary 2015 to January 2024.The patients were divided into the burn shock phase(burn duration<2 days,n=18)and the burn infection phase(burn duration≥2 days,n=46)according to the start time of CBP treat-ment.General datas,total body surface area burned(TBSA),abbreviated burn severity index(ABSI),hemato-crit(HCT)at the start of CBP treatment,platelet count(PLT),activated partial thromboplastin time(APTT),serum creatinine,urea nitrogen,total bilirubin,acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score,sequential organ failure assessment(SOFA)score,Child-Pugh score,filter usage time for each CBP treatment,the incidence of unplanned treatment termination,blood gas analysis,and adverse e-vents were compared between the two groups.Results Compared with the burn shock phase,the levels of HCT and PLT in the burn infection phase were lower,the levels of urea nitrogen and the incidences of shock,hyperlactatemia and hypoxemia were higher,the filter usage time was longer,and the incidence of unplanned treatment termination was lower,the differences were statistically significant(P<0.05).The results of mult-ivariate COX regression analysis showed that the burn shock phase was a protective factor for the filter usage time(P<0.05).Among the 64 patients,citrate accumulation occurred in 2 patients(3.1%),both of which were septic shock combined with hyperlactatemia during the burn infection stage.Patients with acid-base im-balance and electrolyte disorder were corrected after adjusting the treatment.There were 5 new bleeding e-vents,all of which were caused by the primary diseases.Conclusion RCA is safe and effective for CBP treat-ment in severe burned patients and can be used as a routine anticoagulant method.
