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.

ObjectiveA qualitative analysis method was established for the composition of Astragali Radix（AR） before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice（ARR）， the structures of their major compounds were deduced and identified， and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detect the samples of AR and ARR in positive and negative ion modes， respectively. The compounds were analyzed and identified through self-constructed databases， literature， and reference standards， etc. And the data were analyzed by chemometrics， in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR， including 41 flavonoids， 19 terpenoids， 26 organic acids， 8 amino acids， 5 nucleotides， 5 carbohydrates and 19 other compounds. Among them， there were 95 common components in both， 18 unique components in AR， and 10 unique components in ARR. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying， and a total of 26 constituents with differences in the content were screened out， including L-canavanine， L-pyroglutamic acid， L-phenylalanine， cis-caffeic acid， and malonylastragaloside Ⅰ. Among them， 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids， terpenoids， and organic acids， and analyzes the components with significant differences in content between the two in combination with chemometrics， and the differential components are dominated by amino acids， organic acids and terpenoids， which can provide reference for the subsequent quality control and material basis research.

(±)-Talapyrones A-F (1-6), six pairs of dimeric polyketide enantiomers featuring unusual 6/6/6 and 6/6/6/5 ring systems, were isolated from the fungus Talaromyces adpressus. Their structures were determined by spectroscopic analysis and HR-ESI-MS data, and their absolute configurations were elucidated using a modified Mosher's method and electronic circular dichroism (ECD) calculations. (±)-Talapyrones A-F (1-6) possess a 6/6/6 tricyclic skeleton, presumably formed through a Michael addition reaction between one molecule of α-pyrone derivative and one molecule of C₈ poly-β-keto chain. In addition, compounds 2/3 and 4/5 are two pairs of C-18 epimers, respectively. Putative biosynthetic pathways of 1-6 were discussed.

Objective: To comprehensively evaluate the clinical efficacy of a single dose of tranexamic acid (TXA) in reducing perioperative blood loss in patients undergoing craniomaxillofacial plastic and cosmetic surgery through meta-regression analysis. Methods: Embase, PubMed, Wanfang Data, VIP database, China National Knowledge Infrastructure (CNKI), the Chinese Clinical Trial Registry (ChiCTR) and Cochrane Central Register of Controlled Trials (CENTRAL) were electronically retrieved to collect clinical studies evaluating efficacy of perioperative TXA administration in patients undergoing craniomaxillofacial plastic and cosmetic surgery, from inception to August 2024. Quality assessment of randomized controlled trials (RCTs) was performed using Cochrane Collaboration's Risk of Bias Tool. Based on the results of methodological heterogeneity, corresponding meta-analyses were conducted using either random-effects or fixed-effects models in R programming software. Results: Thirty-one articles were included, involving 2 072 patients who underwent craniomaxillofacial plastic and cosmetic surgeries. Among these patients, 1 051 were in the TXA treatment group, and 1 021 were in the control group. The paired meta-analysis showed that compared with the control group, the use of TXA significantly reduced bleeding volume in perioperative patients [standardized mean difference (SMD)=-1.13; 95%CI (-1.47, -0.80), P<0.001]. Subgroup analysis revealed that TXA significantly reduced intraoperative bleeding volume in patients across different surgeries, with the order of efficacy as follows: orthognathic surgery [SMD=-1.44; 95%CI (-2.07, -0.80), P<0.001], cleft palate repair [SMD=-1.32; 95%CI (-2.14, -0.50), P<0.001], rhinoplasty [SMD=-0.97; 95%CI (-1.63, -0.30), P<0.001], and craniosynostosis [SMD=-0.96; 95%CI (-1.40, -0.53), P=0.040]. The result of the meta regression showed there was no significant difference in the hemostatic effect of TXA on patients with increasing doses (5, 10, 15, 20, 25 mg/kg) (P=0.650). Sensitivity analysis verified that the pooled values were stable and reliable. The Egger's test indicated a certain degree of publication bias (Z=-3.40, P<0.001). Conclusion: Existing evidence suggests that TXA effectively reduces perioperative blood loss in patients undergoing craniofacial plastic surgery, regardless of its dosage administered.

Objective:To investigate the role of alkylation repair homolog 5(ALKBH5)-mediated N6-methyladenosine(m6A)modifi-cation in endometrial decidualization.Methods:The mouse models of pregnancy and pseudopregnancy were established,and quantita-tive real-time PCR and Western blot were used to measure the expression pattern of ALKBH5 in the endometrium.The mouse and cell models of artificially induced decidualization were established,and quantitative real-time PCR,Western blot,and immunohistochemis-try were used to measure the expression levels of decidualization-related markers.The EpiQuik m6A RNA methylation quantification kit was used to measure the level of m6A.The mouse and cell models of artificially induced decidualization with interference of ALKBH5 expression were established,and quantitative real-time PCR,Western blot,and immunohistochemistry were used to measure the expression levels of decidualization-related markers,cell proliferation marker molecules,and apoptosis molecules.Flow cytometry was used to measure cell apoptosis rate.Results:In the mouse model of pregnancy,the expression level of ALKBH5 at the uterine em-bryo implantation site was significantly higher than that adjacent to the implantation site,and in the mouse and cell models of artifi-cially induced decidualization,compared with the control group,the induction group had a significant increase in the expression level of ALKBH5 and a significant reduction in the level of m6A.Inhibiting the expression of ALKBH5 led to an increase in the level of m6A,which in turn inhibited the proliferation of stromal cells,induced cell apoptosis,and ultimately impaired the normal process of en-dometrial decidualization.Conclusion:ALKBH5 deficiency leads to an increase in the level of m6A and decidualization injury in the en-dometrium,which lays a foundation for the research on m6A modifi-cation in decidualization.

Objective To explore the efficacy and safety of oxycodone and midazolam for endoscopic retrograde cholangio-pancreatography(ERCP)under awake sedation.Methods Patients scheduled for elective ERCP in the department of gastroenterology of Xuzhou Central Hospital from January 2021 to December 2022 were prospectively recruited and randomly divided into the control group(pethidine combined with diazepam)and the experimental group(oxycodone combined with midazolam).Visual Analogue Scale(VAS)score,Ramsay Sedation Scale(RSS)score,heart rate(HR),respiratory rate(RR),blood oxygen saturation(SpO2),mean arterial pressure(MAP)and postoperative C-reactive protein and blood amylase levels were observed and compared between the two groups of patients before the procedure(T0),at the time of entry(T1),at the time of the opening of the endoscope into the duodenal papilla(T2),at the time of exit(T3).Additionally,incidence of adverse events,patient and endoscopist satisfaction were compared between the two groups.Results A total of 60 patients were included,30 in each group.The difference in the trends of VAS and RSS scores over time between the two groups was statistically significant(Ptime×treatment＜0.05).Compared to the control group,the experimental group had lower VAS scores and higher RSS scores at T1,T2 and T3(P＜0.05).The differences in SpO2 and MAP changes over time between the two groups were statistically significant(Ptime×treatment＜0.05),with higher values observed in the experimental group at T1-T3(P＜0.05).The incidence of pain,coughing and agitation in the experimental group was lower during the procedure(P＜0.05).Both endoscopist and patient satisfaction were significantly higher in the experimental group(P＜0.05).Conclusion Compared with pethidine combined with diazepam,oxcyodone combined with midazolam as a preoperative medication for awake sedation in ERCP treatment is more effective and safer.

Objective To analyze differences in the intestinal microbiota and transcriptomics between N-methyl-N'-nitro-N-nitrosoguanidine(MNNG)gastric cancer rats and normal rats and to analyze the correlation between the two,so as to provide a reference for related studies using MNNG gastric cancer rats as a model.Methods A total of 12 Wistar rats were randomly divided into normal(NM)and gastric cancer(GC)groups.The GC group was given a concentration of 20 mg/mL of MNNG by gavage with a dose of 100 g/mL once a day,and the NM group was given the same amount of normal saline by gavage.Samples were collected for testing after 16 weeks of continuous intervention.The gastric tissues were collected and stained by HE staining to observe morphological changes in the gastric mucosa of the two groups,and the expression levels of differential genes were detected by transcriptome sequencing.The cecal contents were collected for 16S rRNA sequencing.Results(1)Visual observation and HE results showed that the volume of gastric mucosa in the NM group was normal,the surface was glossy,the gastric wall was elastic,the direction of the mucosal folds was regular,there were no hyperplasia or hemorrhagic spots.In the GC group,the volume of gastric mucosa was reduced,the gastric wall was thinned,elasticity was poor,the direction of the folds was disordered and irregular,and there was a bulge accompanied by yellow-black keratotic hyperplasia.In the NM group,the squamous epithelial layer,submucosa,and muscular layer of the gastric mucosa were clear,with no hyperplasia and keratinization.In the GC group,the gastric mucosa had disorganized layers and cell polarity,with different cell morphologies;the squamous epithelial layer was destroyed,and squamous epithelial cells were hyperplasic,keratinized,and had invaded the muscular layer by proliferation.The modeling was considered successful.(2)The results of intestinal microbiota sequencing showed that the abundance of Akkermansia and Lactobacillus in MNNG gastric cancer rats decreased significantly,and the abundance of the rumen coccaceae Prevonella,and Blauter increased significantly.(3)The three key pathways obtained by transcriptomic sequencing and KEGG pathway enrichment analysis were amebiasis,systemic lupus erythematosus,and the PI3K-Akt signaling pathway,and five genes differentially enriched in these three pathways were those for MCPT8I2,IGH-6,IGHG1,ACTN2,and VEGF-D.(4)Combined analysis of intestinal microbiota and transcriptomics showed that_UCG-005,Prevonella_UCG-003 and Brautella were positively correlated with amebiasis,systemic lupus erythematosus,and the PI3K-Akt signaling pathway.Conclusions The abundance of intestinal microbiota in gastric cancer rats formed by MNNG gavage is different from that of normal rats.The genes for MCPT8I2,IGH-6,IGHG1,ACTN2 and VEGF-D may be up-regulated in gastric cancer induced by MNNG gavage.Combined analysis of intestinal microbiota and differential genes suggested that the mechanism of MNNG carcinogenesis may be mainly related to the destruction of gastric mucosa and the inflammatory response.

Objective:To explore the expression level of Porphyromonas gingivalis, downstream of tyrosine kinase 3 (DOK3) and tumor-associated macrophage (TAM) in the tumor immunomicroenvironment of oral squamous cell carcinoma (OSCC) and the correlation with clinicopathological characteristics and prognosis of patients.Methods:A retrospective case-control study was conducted. The clinical data of 200 OSCC patients with Porphyromonas gingivalis-positive confirmed by 16S rDNA sequencing technology in the First Affiliated Hospital, Xinjiang Medical University between June 2008 and June 2020 were collected. The tumor tissues and the corresponding adjacent normal mucosal tissues of 6 OSCC patients (including 3 cases with Porphyromonas gingivalis -positive and 3 cases with Porphyromonas gingivalis-negative) were selected for high-throughput sequencing to screen differentially co-expressed genes. Immunohistochemistry method was used to detect the expressions of Porphyromonas gingivalis, DOK3, and CD206 (a TAM marker). The median H score of OSCC tissues was used as the threshold to categorize the expression level of Porphyromonas gingivalis, DOK3 and CD206 into low-expression (H score < threshold) and high-expression (H score ≥ threshold) groups. The overall survival (OS) analysis was conducted by using the Kaplan-Meier method, and the log-rank test was employed.Results:The high-throughput sequencing results revealed that DOK3 is a differentially co-expressed gene among normal oral mucosa, Porphyromonas gingivalis-positive, and Porphyromonas gingivalis-negative OSCC. In 200 patients with Porphyromonas gingivalis-positive OSCC, 139 exhibited high expression of Porphyromonas gingivalis (H score ≥ 7 points), while 61 showed low expression (H score < 7 points). There were statistically significant differences in the expression levels of Porphyromonas gingivalis in patients with different survival status, pathological T stage, pathological N stage, clinical stage, tumor diameter, degree of tumor differentiation and recurrence (all P < 0.05). Among the 139 OSCC patients with high expression of Porphyromonas gingivalis, 92 cases showed high expression of DOK3 (H score ≥ 6 points) and 47 showed low expression (H score < 6 points); 78 cases exhibited high expression of CD206 (H score ≥ 6 points), while 61 showed low expression (H score < 6 points). There were statistically significant differences in the DOK3 expression level in the high expression of Porphyromonas gingivalis OSCC patients with different age, survival status, pathological T stage, pathological N stage, and recurrence (all P < 0.05). There were statistically significant differences in the CD206 expression level in the high expression of Porphyromonas gingivalis OSCC patients with different pathological T stage, clinical stage, and degree of tumor differentiation (all P < 0.05). The expression of Porphyromonas gingivalis was positively correlated with the expressions of DOK3 and CD206 (both P < 0.01). At the last follow-up on April 6th, 2024, the median follow-up time was 45 months (3 to 106 month range). The median OS time of the 200 patients was 2 429 d, and the 3-year OS rate was 63.9%. The OS of OSCC patients with high expressions of Porphyromonas gingivalis, DOK3, and CD206 was worse than that in those with low expressions (all P < 0.05). Conclusions:The high expression levels of Porphyromonas gingivalis, DOK3, and TAM are associated with a poor prognosis of OSCC patients, suggesting their potential as key biomarkers for prognostic evaluation.

Objective:To compare the dose-response effects of single-fraction ultra-high dose rate (FLASH) and conventional dose rate (CONV) whole abdominal irradiation (WAI) with X-rays on acute radiation-induced intestinal injury in mice, in order to identify optimal dose parameters and potential mechanisms.Methods:A total of 186 male C57BL/6J mice were randomly assigned to a non-irradiation group ( n=6), FLASH irradiation groups ( n=90), and CONV irradiation groups ( n=90). Acute radiation-induced intestinal injury models were established using single-fraction WAI with 11, 12, 13, 14, and 15 Gy X-rays (200 Gy/s for FLASH and 4 Gy/min for CONV). Changes in body weight, stool characteristics, and disease activity index (DAI) scores were assessed at 9 d post-irradiation. At 7 d post-irradiation at 11, 12, and 13 Gy, the intestines were collected for macroscopic examination and length measurement. The small intestine was selected for HE staining and quantitative analysis of intestinal crypt number and mucosal epithelial thickness. The survival of mice was assessed at 15 d post-WAI across all dose groups. Results:After single-fraction WAI at 11, 12, and 13 Gy, the body weight was higher in the FLASH group than that in the CONV group ( t=10.17, 12.65, 10.16, P<0.05). The DAI scores for the FLASH group were 1.00±1.10, 3.17±0.75, and 2.83±1.17, respectively, which were lower than those of the CONV group (4.33±0.52, 7.00±0.00, 8.60±0.55; t=8.70, 11.71, 14.99, P<0.05). However, after WAI at 14 Gy and 15 Gy, there were no significant differences in body weight and DAI between the FLASH group and the CONV group ( P>0.05). At 7 d after single-fraction WAI at 11, 12, and 13 Gy, mice in the FLASH group exhibited less intestinal congestion, edema, and shortening compared with the CONV group. The difference between the FLASH and CONV groups were statistically significant in small intestine length at 11 and 13 Gy ( t=4.42, 3.78, P<0.05), and in colorectal length at 11 and 12 Gy ( t=3.97, 3.12, P<0.05). Small intestine HE staining revealed superior preservation of intestinal architecture in the FLASH group compared with the CONV group, characterized by longer villi, increased crypt numbers, thicker mucosal epithelium, and enhanced structural integrity. The differences in crypt number and mucosal epithelial thickness were statistically significant ( tcrypt=13.10, 23.80, 11.90; tmucosal=5.75, 2.64, 7.74; P<0.05). At 15 d post-irradiation, the survival rate in the 15 Gy FLASH group was higher than that in the CONV group (50% vs. 10%, χ2=5.39, P<0.05), with a median survival extension of 6 d ( HR=0.340, 95% CI: 0.115 4-0.999 9). No significant survival differences were observed between the FLASH group and the CONV group at 11, 12, 13, and 14 Gy ( P>0.05). Conclusions:FLASH irradiation significantly alleviated acute radiation-induced intestinal injury from medium single-fraction WAI with 11, 12, and 13 Gy X-rays compared with CONV irradiation, and showed potential to improve mouse survival after single-fraction WAI at 15 Gy. This effect is likely associated with the preservation of intestinal crypts and exhibits a dose-dependent relationship.
