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.

Coronavirus disease 2019 (COVID-19) is a multi-system disease that can lead to various severe complications. Acute limb ischemia (ALI) has been increasingly recognized as a COVID-19-associated complication that often predicts a poor prognosis. However, the pathophysiology and molecular mechanisms underlying COVID-19-associated ALI remain poorly understood. Hypercoagulability and thrombosis are considered important mechanisms, but we also emphasize the roles of vasospasm, hypoxia, and acidosis in the pathogenesis of the disease. The angiotensin-converting enzyme 2 (ACE2) pathway, inflammation, and platelet activation may be important molecular mechanisms underlying these pathological changes induced by COVID-19. Furthermore, we discuss the hypotheses of risk factors for COVID-19-associated ALI from genetic, age, and gender perspectives based on our analysis of molecular mechanisms. Additionally, we summarize therapeutic approaches such as use of the interleukin-6 (IL-6) blocker tocilizumab, calcium channel blockers, and angiotensin-converting enzyme inhibitors, providing insights for the future treatment of coronavirus-associated limb ischemic diseases.

Objective:To explore the diagnostic value of fractional flow reserve (FFR) based on optical coherence tomography (OCT) for coronary functional ischemia, and to investigate the feasibility of synchronously obtaining Doppler blood flow velocity information with the help of OCT technology.Methods:This study was a single-center, prospective, self-controlled clinical study on coronary heart disease patients who underwent OCT and FFR assessment at Department of Cardiology, the Second Hospital of Jilin University from January 2024 to February 2025. Linear regression analysis was used to evaluate the correlation and consistency between OCT-FFR and FFR. With FFR≤0.80 as the gold standard for judging whether the target vessel was ischemic, the diagnostic performance of OCT-FFR was evaluated, and the diagnostic value of OCT-FFR for significant coronary artery ischemia was assessed using subject operating characteristic curves. Blood flow OCT data were analyzed by Doppler processing algorithm to obtain information on coronary blood flow velocity.Results:A total of 31 vessels from 28 patients were analyzed, the correlation coefficient r between OCT-FFR and FFR of the 31 vessels was 0.84 ( P<0.001). With FFR as the gold standard to determine whether a coronary artery is ischemic, accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for OCT-FFR was 93.55%, 75.00%, 100.00%, 1.00, 0.92. In clinical practice, Doppler OCT was used for the first time to obtain information on coronary blood flow velocity. Conclusion:OCT-FFR had an excellent correlation and consistency with FFR in judging whether there is coronary artery ischemia. The feasibility of the simultaneous acquisition of OCT-FFR and Doppler flow velocity information in coronary stenosis was preliminarily verified.

There are many cases of biliary stent migration. Generally, biliary stent migrates distally. While, biliary stent rarely migrates proximally. Here we reported the case of a 49-year-old woman who underwent robot assisted right hemihepatectomy, and placement of a biliary stent for complicating bile leakage. The patient was discharged from hospital after recovering from bile leakage. Five months later, a follow-up examination revealed that the biliary stent had shifted into the liver, leading to liver perforation. We fully removed the stent by using a stone retrieval balloon and a snare. We suggested that when useing a biliary stent, it is necessary to consider of appropriate length of the stent and inform the patient when to return to the hospital for stent removal, in order to avoid stent migration and complications occurrence.

Objective:To observe the efficacy of hypertonic dextrose injection(prolotherapy)at retrodiscal tissue in the treatment of chronic joint pain in patients with temporomandibular disorders(TMD).Methods:From June 2012 to March 2022,244 patients(aged 16 to 75 years)underwent the treatment were included and classified according to DC/TMD.The treatment started from an anesthetic in-jection of 2％lidocaine(1.5-2 mL)into the retrodiscal tissue.The patients were then instructed to perform mandibular condylar exercise for 5-10 min,prior to the therapeutic injection of 50％dextrose(1-1.5 mL)by using the same method.Assessment of TMJ pain and jaw function was performed at 2 weeks,2,6 and 12 months after injection.Results:By March 2022,221 cases completed the final sur-vey(the rate of loss of follow-up was 9.4％),the average follow-up time was(75.7±25.1)months.2 weeks after treatment,there was significant relief of joint pain,and mandibular function was significantly improved in most patients by 2 month after treatment.Of these,186 cases achieved profound pain relief and faily normal jaw function,17 cases with recurrence of joint pain and jaw dysfunction and op-ted for occlusal splint treatment due to fear of injection,16 cases claimed no obvious therapeutic effect but rejected any further tratment,2 cases subsequently accepted TMJ surgery.There was no worsening of TMD or other complication as a result of the treatment.Conclu-sion:Hypertonic dextrose injection in retrodiscal tissue attachment is straightforward,safe and effective in the treatment of chronic joint pain and TMD.

Objective:To prepare the chitin/hyaluronic acid/collagen hydrogel loaded with mouse adipose-derived stem cells and to explore its effects on wound healing of full-thickness skin defects in rats.Methods:The research was an experimental research. Chitin nanofibers were prepared by acid hydrolysis and alkaline extraction method, and then mixed with hyaluronic acid and collagen to prepare chitin/hyaluronic acid/collagen hydrogels (hereinafter referred to as hydrogels). Besides, the hydrogels loaded with mouse adipose-derived stem cells were prepared. Thirty male 12-week-old guinea pigs were divided into negative control group, positive control group, and hydrogel group according to the random number table, with 10 guinea pigs in each group. Ethanol, 4-aminobenzoic acid ethyl ester, or the aforementioned prepared hydrogels without cells were topically applied on both sides of back of guinea pigs respectively for induced contact and stimulated contact, and skin edema and erythema formation were observed at 24 and 48 h after stimulated contact. Adipose-derived stem cells from mice were divided into normal control group cultured routinely and hydrogel group cultured with the aforementioned prepared hydrogels without cells. After 3 d of culture, protein expressions of platelet-derived growth factor-D (PDGF-D), insulin-like growth factor-Ⅰ (IGF-Ⅰ), and transforming growth factor β 1 (TGF-β 1) were detected by Western blotting ( n=3). Eight male 8-week-old Sprague-Dawley rats were taken and a circular full-thickness skin defect wound was created on each side of the back. The wounds were divided into blank control group without any treatment and hydrogel group with the aforementioned prepared hydrogels loaded with adipose-derived stem cells applied. Wound healing was observed at 0 (immediately), 2, 4, 8, and 10 d after injury, and the wound healing rate was calculated at 2, 4, 8, and 10 d after injury. Wound tissue samples at 10 d after injury were collected, the new tissue formation was observed by hematoxylin-eosin staining; the concentrations of interleukin-1α (IL-1α), IL-6, IL-4, and IL-10 were detected by enzyme-linked immunosorbent assay method; the expressions of CD16 and CD206 positive cells were observed by immunohistochemical staining and the percentages of positive cells were calculated. The sample numbers in animal experiment were all 8. Results:At 24 h after stimulated contact, no skin edema was observed in the three groups of guinea pigs, and only mild skin erythema was observed in 7 guinea pigs in positive control group. At 48 h after stimulated contact, skin erythema was observed in 8 guinea pigs and skin edema was observed in 4 guinea pigs in positive control group, while no obvious skin erythema or edema was observed in guinea pigs in the other two groups. After 3 d of culture, the protein expression levels of PDGF-D, IGF-I, and TGF-β 1 in adipose-derived stem cells in hydrogel group were significantly higher than those in normal control group (with t values of 12.91, 11.83, and 7.92, respectively, P<0.05). From 0 to 10 d after injury, the wound areas in both groups gradually decreased, and the wounds in hydrogel group were almost completely healed at 10 d after injury. At 4, 8, and 10 d after injury, the wound healing rates in hydrogel group were (38±4)%, (54±5)%, and (69±6)%, respectively, which were significantly higher than (21±6)%, (29±7)%, and (31±7)% in blank control group (with t values of 3.82, 3.97, and 4.05, respectively, Pvalues all <0.05). At 10 d after injury, compared with those in blank control group, the epidermis in wound in hydrogel group was more intact, and there were increases in hair follicles, blood vessels, and other skin appendages. At 10 d after injury, the concentrations of IL-1α and IL-6 in wound tissue in hydrogel group were significantly lower than those in blank control group (with tvalues of 8.21 and 7.99, respectively, P<0.05), while the concentrations of IL-4 and IL-10 were significantly higher than those in blank control group (with tvalues of 6.57 and 9.03, respectively, P<0.05). The percentage of CD16 positive cells in wound tissue in hydrogel group was significantly lower than that in blank control group ( t=8.02, P<0.05), while the percentage of CD206 positive cells was significantly higher than that in blank control group ( t=7.21, P<0.05). Conclusions:The hydrogel loaded with mouse adipose-derived stem cells is non-allergenic, can promote the secretion of growth factors in adipose-derived stem cells, promote the polarization of macrophages to M2 phenotype in wound tissue in rats with full-thickness skin defects, and alleviate inflammatory reaction, thereby promoting wound healing.

Objective To observe the effects of folic acid(FA)supplementation on the expression of Flotillin-1 and β-amyloid protein(Aβ)-metabolism-related proteins in the brains of inflammation-stimulated Alzheimer's disease(AD)mice.Methods Twenty-seven 6-month-old male APP/PS1 mice were randomly divided into AD,AD+LPS,and AD+LPS+FA groups,with nine mice in each group.Nine C57BL/6J male mice born within the same month were used as the Control group.The AD+LPS+FA group was given folic-acid-supplemented feed(8 mg/kg)for 3 months of intervention,while the other three groups were fed normal feed.Lipopolysaccharide solution(LPS,250 μg/(kg·d))was injected intraperitoneally into mice in the AD+LPS and AD+LPS+FA groups 1 week before the end of the experiment,and saline was injected into the remaining two groups.The serum inflammatory factors TNF-α and IL-6 levels and brain tissue Aβ1-40 and Aβ1-42 levels of mice in each group were detected by ELISA.Flotillin-1 protein expression in brain tissue was detected using Western blot,and the co-expression of Flotillin-1 and Aβ1-42/APP/PS1/BACE1 in the cortical region of the brain was detected via immunofluorescence double-labeling.Results After ANOVA analysis,we found mice in the AD group had elevated serum TNF-α and IL-6 levels(P＜0.05),elevated levels of Aβ1-40 and Aβ1-42(P＜0.05),increased expression of Flotillin-1 protein(P＜0.05),and increased co-expression of Flotillin-1 and Aβ1-42/APP/PS1/BACE1 in the cortical brain tissue(P＜0.05)compared with the Control group.Compared with mice in the AD group,those in the AD+LPS group had further increases in serum inflammatory factors and Aβ levels in the brain(P＜0.05)and increased co-expression of Flotillin-1 and Aβ1-42/APP/BACE1 double-labeled proteins in their cortical brain tissue(P＜0.05).Compared with mice in the AD+LPS group,those in the AD+LPS+FA group had lower in vivo inflammation levels and Aβ content in the brain(P＜0.05),lower brain tissue Flotillin-1 protein expression(P＜0.05),and lower Flotillin-1 and Aβ1-42/APP/PS1/BACE1 protein co-expression in cortical brain tissue(P＜0.05).Conclusions Folic acid supplementation may reduce Flotillin-1 protein expression and Aβ deposition in the brain of AD inflammatory mice.
