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 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 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.

OBJECTIVE To observe the clinical efficacy of Zhenshi Burn Ointment on postoperative wound healing of simple anal fistula and explore its potential mechanism of action.METHODS A total of 60 patients with low-position simple anal fistula of damp-heat pouring downward type admitted to the Department of Anorectum,Nanjing Hospital of Chinese Medicine Affiliated to Nan-jing University of Chinese Medicine from May to December 2023 were selected as the research subjects and randomly divided into an experimental group and a control group,with 30 cases in each group.After surgery,the control group was given sterilized vaseline gauze for external application,and the experimental group was given Zhenshi Burn Ointment for external application.The course of treatment for both groups was 30 d.After treatment,the postoperative wound healing time,wound healing rate,pain score,wound granulation growth and secretion,and changes in TCM syndrome score were compared between the two groups.The pathological sec-tions of wound granulation tissue were compared 14 d after surgery.The transcription levels of COL1A1,type Ⅲ collagen(COL3A1),epidermal growth factor(EGF),and fibroblast growth factor(FGF2)in granulation tissue were detected by qPCR.The expression lev-els of proteins related to MEK/ERK signaling pathway were detected by Western blot.RESULTS Compared with the control group,the wound healing rates of the experimental group were significantly increased at 7,14,21,and 30 d after surgery(P<0.01),and the wound healing time was significantly shortened(P<0.01).At 7 d after surgery,the pain score of the experimental group was signifi-cantly lower than that of the control group(P<0.05).At 7 and 14 d after surgery,the granulation growth score of the wound in the ex-perimental group was significantly lower than that of the control group(P<0.01).At 14 d after surgery,the secretion score of the ex-perimental group was significantly lower than that of the control group(P<0.01).At 14 and 30 d after surgery,the total score of TCM syndrome in the experimental group was significantly better than that in the control group(P<0.05).At 14 d after surgery,the patho-logical improvement of granulation tissue in the wound in the experimental group was better than that in the control group,and the con-tent of collagen fiber and type I collagen(Collagen I)was significantly higher than that in the control group(P<0.01).The mRNA contents of COL1A1,COL3A1,EGF,and FGF2 were significantly higher than those in the control group(P<0.05,P<0.01);the levels of p-MEK1/2 and p-ERK1/2 proteins were higher than those in the control group(P<0.05).CONCLUSION Zhenshi Burn Ointment has a good effect on promoting postoperative anal fistula wound healing,which may be related to upregulating growth factor expression,promoting collagen regeneration,and activating MEK/ERK pathway.

Objective:To explore the learning curve of primary urologists mastering Holmium laser enucleation of the prostate for the treatment of large volume benign prostatic hyperplasia (BPH).Methods:The clinical data of 92 patients with larger volume BPH who received HoLEP performed by a urologist in Beijing Friendship Hospital Pinggu Campus, Capital Medical University were retrospectively reviewed. 92 patients were divided into group A (1-23 cases, n=23), group B (24-46 cases, n=23), group C (47-69 cases, n=23), and group D (70-92 cases, n=23) based on the sequence of surgery. The clinical characteristics, including prostate volume, operation time, enucleation efficiency, indwelling catheter time, decrease value of hemoglobin, intraoperative blood transfusion, perioperative complications, and international prostate symptom score (IPSS), quality of life (QOL) score, Qmax, and postvoid residual urine (PVR) at 3 months postoperatively were compared between the four groups. Measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for comparisons among multiple groups, and t-test was used for comparisons between two groups. Count data were expressed as the cases and percentage, and the Chi-square test was used for comparison between groups. Results:There were significant differences among the four groups in terms of operation time [(94.43±8.26) min, (86.39±5.89) min, (70.70±5.64) min, (64.70±4.23) min, P=0.001], enucleation efficiency [(0.90±0.08) mL/min, (1.01±0.07) mL/min, (1.23±0.12) mL/min, (1.34±0.12) mL/min, P=0.001], decrease value of hemoglobin [(25.98±1.39) g/L, (23.27±1.49) g/L, (20.03±1.07) g/L, (18.49±0.96) g/L, P=0.001] and indwelling catheter time [(5.91±1.54) d, (5.35±1.27) d, (3.39±0.72) d, (3.04±0.64) d, P=0.001]. Compared with group C and group D, the operation time was longer, the enucleation efficiency was lower, the decrease value of hemoglobin before and after the operation was higher, and the indwelling catheter time was longer, the above differences were all statistically significant ( P<0.05). However, there was no statistically significant difference between group A and group B, or group C and group D ( P>0.05). Among the 92 patients, only 3 patients received blood transfusion during operation, including 2 patients in group A and 1 patient in group B. 2 patients underwent surgical complications during the perioperative period. Among them, 1 patient suffered bladder wall injury due to improper operation of the tissue pulverizer in group A, and 1 patient developed prostatic capsule perforation in group B. Furthermore, after 56 cases of operation, a primary urologist can perform HoLEP surgery quickly and safely. Conclusion:The learning curve of a primary urologist mastering HoLEP for larger volume (≥ 80 mL) BPH was 56 procedures, and the operation efficiency and safety were significantly improved.
