Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease， making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine （TCM） in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation， using standardized measurements of the overall TCM condition， multi-omics research of hematologic tumors， and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma， thereby establishing a risk warning system for virus-related lymphoma. At the same time， a TCM health management approach will be applied to manage and regulate virus-related lymphoma， interrupting its progression and forming a human-centered， comprehensive， continuous health service model. Based on this， a standardized， integrated clinical prevention and treatment decision-making model for virus-related lymphoma， recognized by both Chinese and western medicine， will be established to provide TCM solutions for primary prevention of major malignant tumors.

Objective: To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators. Methods: From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed. Results: Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05). Conclusion The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

AIM:To investigate the value of optical coherence tomography angiography(OCTA)indicators in the diagnosis of diabetic retinopathy(DR), and to provide patients with diabetic nephropathy(DN)with more sensitive OCTA screening indicators to detect concurrent DR at an early stage.METHODS: A total of 200 patients who treated in the ophthalmology department of the Seventh Affiliated Hospital, Sun Yat-sen University from 2022 to 2023 were included, including 95 first-diagnosed DR patients and 105 patients without DR, and all patients underwent OCTA examination and a collection of demographics and renal function parameters. After a quality check, automated measurements of the foveal avascular zone area, vessel density(VD), and perfusion density(PD)of both 3 mm×3 mm and 6 mm×6 mm windows were obtained.RESULTS: Using random forest and multivariate Logistic regression methods, we developed a diagnostic model for DR based on 12 variables(age, FBG, SBP, DBP, HbA1c, ALT, ALP, urea/Scr, DM duration, HUA, DN, and CMT). Adding specific OCTA parameters enhanced the efficacy of the existing diagnostic model for DR(outer vessel density in 6 mm×6 mm window, AUC=0.837 vs 0.819, P=0.03). In the study of DN patients, the parameters in the 6 mm×6 mm window improved the diagnostic efficacy of DR(inner VD; outer VD; full VD; outer PD; full PD).CONCLUSION:The outer VD in the 6 mm×6 mm window can enhance the efficacy of the traditional DR diagnostic model. Meanwhile, compared with the 3 mm×3 mm window, the microvascular parameters in the 6 mm× 6 mm window focusing on DN patients can be more sensitive to diagnosing the occurrence of DR.

BACKGROUND:Acute myocardial infarction can cause cardiac remodeling and heart failure,as well as skeletal myopathy,affecting patients'quality of life.Exercise therapy is an important rehabilitation method for patients with heart failure;however,the optimal exercise prescription has not been clarified. OBJECTIVE:To compare the effects of different exercise modes(aerobic exercise,resistance exercise)on skeletal muscle remodeling in rats with acute myocardial infarction induced heart failure and to explore the possible mechanism,so as to provide a basis for optimizing the exercise rehabilitation program. METHODS:Forty-eight Sprague-Dawley rats were randomly divided into sham operation group,myocardial infarction group,aerobic exercise group and resistance exercise group.Coronary artery ligation was used to create model of heart failure.After 3 months,animals in the aerobic exercise group and resistance exercise group underwent 12 weeks of corresponding exercise mode interventions,while those in the sham operation group and myocardial infarction group were kept quietly in mouse cages.After the experiment,maximal running speed and maximal weight-bearing load were measured by graded treadmill exercise test and ladder-climbing test respectively,and heart structure and function were evaluated by echocardiography.The heart was isolated,and hematoxylin-eosin staining and Sirius red staining were performed to detect cardiac remodeling.For the gstrocnemius muscle,ATPase staining was performed to observe changes in muscle fiber type and cell cross-sectional area,dihydroethidium method was used to evaluate reactive oxygen species levels,enzyme-linked immunosorbent method was used to determine malondialdehyde content and antioxidant enzyme activity,western blot was used to determine the expression of ubiquitin-proteasome system proteins,and the number of activated satellite cells(Pax7+/MyoD+)were detected by double immunofluorescence staining. RESULTS AND CONCLUSION:(1)Exercise performance:Compared with the sham operation group,maximal running speed and maximal weight-bearing load in the myocardial infarction group decreased(P<0.05);compared with the myocardial infarction group,the maximal running speed of the aerobic exercise group and the maximal weight-bearing load of the resistance exercise group increased(P<0.05).(2)Cardiac remodeling:Compared with the sham operation group,infarction area,myocardial cell cross-sectional area,and collagen content in the myocardial infarction group increased(P<0.05),while leftventricular ejection fraction and shortening fraction decreased(P<0.05);compared with the myocardial infarction group,there was no statistical difference in the above parameters in both aerobic exercise resistance exercise groups(P>0.05).(3)Skeletal muscle remodeling:Compared with the sham operation group,gastrocnemius muscle mass,gastrocnemius muscle mass index,cell cross-sectional area,superoxide dismutase activity,glutathione peroxidase activity,and the number of activated satellite cells decreased in myocardial infarction group(P<0.05),while reactive oxygen species content,malondialdehyde content,and the protein expression of ubiquitin,MuRF1 and MAFbx increased(P<0.05);compared with the myocardial infarction group,gastrocnemius muscle mass index,superoxide dismutase activity,the number of activated satellite cells increased in both aerobic exercise and resistance exercise groups(P<0.05),while reactive oxygen species content and the protein expression of ubiquitin,MuRF1,and MAFbx decreased(P<0.05);compared with the aerobic exercise group,gastrocnemius muscle mass,gastrocnemius muscle mass index,cell cross-sectional area,reactive oxygen species content,malondialdehyde content,the number of activated satellite cells increased in resistance exercise group(P<0.05),while superoxide dismutase activity,glutathione peroxidase activity down-regulated(P<0.05).To conclude,aerobic exercise and resistance exercise can both improve exercise performance of rats with heart failure,and the mechanism is related to reducing oxidative stress,inhibiting ubiquitin-proteasome system activity and activating satellite cells to improve skeletal muscle remodeling.Aerobic exercise has a better effect on improving skeletal muscle oxidative stress,while resistance exercise has a more significant effect on promoting skeletal muscle regeneration.

Objective To investigate and analyze epidemiological characteristics of patients with mycoplasma pneumoniae pneumonia (MPP) from 2020 to 2023, and the risk factors for plastic bronchitis (PB), To provide data support for developing preventive measures. Methods The medical records of 2 257 patients with respiratory tract infection treated at Huai'an Hospital Affiliated to Xuzhou Medical University from 2020 to 2023 were collected. Count the number of MPP patients and analyze the MP detection rate. Multivariate logistic regression analysis and ROC curve was used to screen the risk factors for PB. Results A total of 858 cases were positive for MP antibodies, and the detection rate was 38.02%. There are statistically significant differences in MP detection rates among different genders, age groups, and years (P<0.05). Among the 286 patients diagnosed with MPP and undergoing bronchoscopy, 68 (23.78%) patients had PB. According to univariate and multivariate logistic regression analysis, small age, higher N%, D-D, LDH and AST levels were independent risk factors for PB (P<0.05). ROC curve analysis shows that age and combined detection are the most effective indicators for PB prediction, with areas under the curve of 0.998 and 0.961, respectively. Conclusion MP is the main pathogen of respiratory tract infections in the area from 2020 to 2023. Women and children are more susceptible to MP infection. Small age, high N%, DD, LDH and AST levels are independent risk factors for PB in patients with MPP. Targeted preventive measures should be taken for MP susceptible population, and close attention should be paid to PB related risk factors to prevent disease progression and the occurrence of PB.

Aldehyde oxidase (AOX) is a molybdoenzyme that is primarily expressed in the liver and is involved in the metabolism of drugs and other xenobiotics. AOX-mediated metabolism can result in unexpected outcomes, such as the production of toxic metabolites and high metabolic clearance, which can lead to the clinical failure of novel therapeutic agents. Computational models can assist medicinal chemists in rapidly evaluating the AOX metabolic risk of compounds during the early phases of drug discovery and provide valuable clues for manipulating AOX-mediated metabolism liability. In this study, we developed a novel graph neural network called AOMP for predicting AOX-mediated metabolism. AOMP integrated the tasks of metabolic substrate/non-substrate classification and metabolic site prediction, while utilizing transfer learning from ¹³C nuclear magnetic resonance data to enhance its performance on both tasks. AOMP significantly outperformed the benchmark methods in both cross-validation and external testing. Using AOMP, we systematically assessed the AOX-mediated metabolism of common fragments in kinase inhibitors and successfully identified four new scaffolds with AOX metabolism liability, which were validated through in vitro experiments. Furthermore, for the convenience of the community, we established the first online service for AOX metabolism prediction based on AOMP, which is freely available at https://aomp.alphama.com.cn.

Objective sampling method was used to conduct a questionnaire survey on outpatients in two hospitals in Guangdong province in order to evaluate patients’ satisfaction with the quality of medical service. This paper explored the factors that affect patients’ evaluation of medical service quality, and found that patients’ age was negatively correlated with the evaluation of medical service quality. It is suggested that the establishment of friendly medical institutions should be carried out according to the national policy. At the same time, the management mechanism of hospital should be improved, the number of medical service centers for "efficient" should be increased, and the medical service personnel should be regularly trained; carry out medical knowledge education in community, improve the popularization of personal medical knowledge and close the cognitive gap between doctors and patients.

italic>Anoectochilus roxburghii liquid (spray, a hospital preparation of Wu Mengchao Hepatobiliary Hospital of Fujian Medical University) has shown a good clinical treatment effect during the COVID-19 pandemic, but its material basis and mechanism of action are still unclear. In this study, network pharmacology and molecular docking methods were used to predict the molecular mechanism of A. roxburghii liquid against COVID-19, and pharmacodynamic experiments in vitro were conducted to study the interaction between the current targets with clear preventive and therapeutic effects and the key components of A. roxburghii liquid. UPLC-MS and database were used to compare and analyze the active ingredients in the liquid, and 17 potential active ingredients with good drug-like properties were screened by in vivo pharmacokinetics process in SwissADME database. SwissTargetPrediction and GeneCards were searched to find 93 common targets. Cytoscape 3.8.2 software was used to construct the "component-target" network map, and the Metascape platform was used for gene function annotation and pathway enrichment analysis. It was found that the extract could regulate the positive response to external stimuli, inflammatory response, cytokine production and other biological processes by binding the active ingredients such as isorhamnetin, kaempferol, luteolin, quercetin and apigenin to the common targets (NOS3, MPO, MMP3, etc.), and play an anti-COVID-19 role. In the angiotensin-converting enzyme 2 (ACE2) activity inhibition assay, it was found that the stock solution of A. roxburghii liquid (for spray), and the supernatant after removing polysaccharides (mainly containing flavonoids) could to some extent inhibit the activity of ACE2. Crucially, in the experiment of 2019-nCOV-S pseudovirus infecting HEK-293T-ACE2 cells, we found that A. roxburghii liquid may exert anti-COVID-19 effects by blocking the binding of SARS-CoV-S protein to ACE2.

Objective:To analyze the clinical and radiographic effectiveness of a calcium silicate-based bioactive ceramic iRoot BP Plus? pulpotomy of immature permanent teeth with complicated crown fracture and to evaluate the factors influencing its long-term success rate.Methods:The digital medical records of patients under 13 years old who had undergone iRoot BP Plus? pulpotomy in the Department of Oral Emergency or the First Clinical Division,Peking University School and Hospital of Stomatology from March 2017 to September 2022 due to complicated crown fracture of anterior teeth,and had taken at least one post-operation apical radiograph were reviewed.The clinical and radiographic information at the initial examination and follow-up period were obtained,including crown color,mobility,percussion,cold test(partial pulpotomy teeth),dental restoration,fistula,swelling or inflammation of the gingival tissue,the formation of apical foramen,pathologic radiolucency and calcification of pulp chamber or root canal obliteration.Data were tested by Fisher exact test and a multiple comparison.Results:In the study,64 patients including 37 males(57.8％)and 27 females(42.2％)with a mean age of 9.1 years were finally enrolled.The total number of permanent teeth that received pulpotomy was 75,and the average follow-up time was 19.3 months.The success rate was 93.1％with the time interval between dental injury and treatment in 24 h,while the success rate dropped to 88.2％with the time intervals beyond 24 h.The time intervals did not significantly affect the pulp survival rate(P=0.61)after pulpotomy(partial or co-ronal).The success rate 6 months after pulpotomy was 96.0％,and one-year success rate was 94.7％.A total of 23 cases were reviewed for more than 2 years after pulpotomy,and 6 cases failed.The mobility had no significant effect on the success rate(P=0.28).Pulp chamber calcification and pulp canal obli-teration were not observed in all the post-operative radiographs.Conclusion:The one year clinical and radiographic success rates obtained in this study indicate that iRoot BP Plus? is an appropriate pulp cap-ping material option for pulpotomy treatment of complicated crown fracture in immature permanent teeth without displacement injuries.This technique has broad promotional value.
