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.

Bacterial therapy has attracted increasing attention due to its special mechanism and abundant applications. With the flourishing development of synthetic biology, therapeutic genes have been introduced into engineering bacteria to improve their antitumor efficacy. However, it is difficult to spatiotemporally control the expression of these therapeutic genes at the tumor site in vivo, thereby considerably limiting the application of engineered bacteria in tumor treatment. To resolve this problem, we constructed a temperature-responsive bacterial strain capable of triggering the expression of exogenous genes in a laser-controllable way. Noxa, a pro-apoptotic protein, is chosen to test the expression of exogenous protein and its anti-tumor effect in engineered bacteria upon laser irradiation. Firstly, Noxa was fused to the C-terminus of the bacterial outer membrane protein cytolysin A (ClyA), and then the recombinant gene fragment ClyA-Noxa was inserted into the temperature-sensitive plasmid pBV220 and the recombinant plasmid was transformed into non-pathogenic Escherichia coli MG1655. Thus, we constructed the engineering strain (TRB@Noxa) that could express Noxa on the bacterial surface. TRB@Noxa could target and colonize the tumor tissue without causing notable host toxicity. The bacterial infection triggered thrombosis in the tumor tissue, resulting in the darkness of tumor sites. In a xenograft mouse tumor model, our strategy demonstrated precise tumor targeting and strong tumor inhibition. In conclusion, we successfully constructed a new engineering bacterial strain TRB@Noxa. TRB@Noxa combined with photothermal therapy could arrest tumor growth in the absence of photosensitizers, which represents an appealing method for antitumor therapy in the future.

Existing antidepressant treatments are generally suboptimal for patients with bipolar disorder(BD).Several studies have explored the efficacy of light therapy(LT)in patients with bipolar depression,along with investigating parameters,devices,and safety aspects of LT.This paper provides a review of these aspects.Numerous meta-analyses and randomized controlled trials have indicated that LT could significantly improve depressive symptoms in BD patients,with both low and high intensity white light having this effect,while the antidepressant effect of blue light remains unclear.LT takes effect rapidly,preferably in the morning,with each session lasting between 30 to 60 minutes,but there is no consensus on the most beneficial LT course for BD patients.The most commonly used device for LT is a lightbox.However further exploration is need regarding the safety of LT glasses.When LT devices that meet safety standards is selected,the overall safety of LT will be high and risk of manic or hypomanic switch will be low for BD patients.In conclusion,LT holds promise for patients with bipolar depression,and further research on LT for BD patients should be conducted to explore LT strategies and develop LT prescriptions.

Eighty patients with Yin deficiency and heat excessive T2DM treated in the hospital between January and July 2021 were selected, and divided into observation group (41 cases) and control group (39 cases) by random number table method. Patients in the control group were treated with conventional western medicine, and patients in the observation group were treated with modified Xiaoke Prescription on the basis of the control group. Both groups were treated for 1 month. TCM syndrome scores were performed before and after treatment. Fasting plasma glucose (FPG) and 2 hPG were measured by glucose oxidase method. Serum HbA1c, malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels and SOD activity were measured by ELISA. The levels of low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and total cholesterol (TC) were detected by colorimetry.Results:The total effective rate of the observation group was 92.68% (38/41), and that of the control group was 76.92% (30/39). The difference between the two groups was statistically significant ( χ2=3.89, P=0.048). After treatment, the scores of tiredness and fatigue, thirst and appetite, overeating and hunger, redness of tongue and lack of saliva and total scores in the observation group were significantly lower than those in the control group ( t=4.46, 16.89, 13.37, 8.58, 8.38, P<0.01). After treatment, the levels of serum FPG [(7.31±0.90) mmol/L vs. (8.72±1.50) mmol/L, t=5.13], 2 hPG [(9.64±2.05) mmol/L vs. (12.85±1.20) mmol/L, t=8.49], HbA1c [(7.64±0.58)% vs. (8.11±1.35)%, t=2.04] in the observation group were significantly lower than those in the control group ( P<0.05); MDA [(3.96±1.00) mmol/L vs. (5.04±0.73) mmol/L, t=5.49], 8-OHdG [(203.41±30.70) ng/L vs. (234.50±59.00) ng/L, t=2.98] levels were significantly lower than those in the control group ( P<0.05); The activity of serum SOD [(48.64±5.05) mU/L vs. (41.75±3.58) mU/L, t=7.01] was significantly higher than that of the control group ( P<0.01); The serum LDL-C [(2.01±0.11) mmol/L vs. (2.56±0.25) mmol/L, t=12.84], TC [(4.75±0.20) mmol/L vs. (5.12±0.07) mmol/L, t=10.93] levels were significantly lower than those in the control group ( P<0.01); The serum HDL-C [(1.62±0.18) mmol/L vs. (1.24±0.42) mmol/L, t=5.31] level was significantly higher than that of the control group ( P<0.01). Conclusion:The modified Xiaoke Prescription can improve clinical symptoms, curative effect and pancreatic function, and relieve oxidative stress on the patients with T2DM.

Objective:To identify and characterize one Spiroplasma strain (designated as DGKH1) isolated from the blood of a patient with sepsis. Methods:The traditional bacterial culture, staining, morphological observation, physiological and biochemical identification, 16S rRNA gene sequencing, phylogenetic analysis, genome sequencing, and the genome-related index analysis were performed to accurately determine the taxonomic status of the strain DGKH1. Antibiotic susceptibility testing was performed using a specific kit for culturing and testing Ureaplasma urealyticum/ Metamycoplasma hominis. Results:The strain DGKH1 could weakly grow on Columbia blood agar, chocolate agar, and Haemophilus chocolate 2 agar. However, it did not grow in liquid culture medium containing tetracycline (4 μg/ml), doxycycline (1 μg/ml), minocycline (1 μg/ml), josamycin (2 μg/ml), roxithromycin (1 μg/ml), clarithromycin (1 μg/ml), or telithromycin (1 μg/ml). DGKH1 resembling Metamycoplasma hominis formed "fried egg-like colonies" on Mycoplasma solid culture medium. DGKH1 could not be stained by Gram staining. When observed under transmission electron microscopy (TEM) using phosphate buffer as the matrix, the bacteria were spiral-shaped. Results of 16S rRNA gene sequence alignment showed that DGKH1 was highly similar (99.85%) to Spiroplasma eriocheiris CCTCC M 207170 T. However, the urea decomposition test was positive, which was different from all of the known Spiroplasma species. The phylogenetic analysis based on whole genome showed that DGKH1 was clustered in a small branch along with Spiroplasma eriocheiris CCTCC M 207170 T. However, the average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between the two strains were 94.14% and 56.00%, respectively, both below the threshold for prokaryotic species identification. Conclusions:DGKH1 represented a potential new species of genus Spiroplasma, closely related to Spiroplasma eriocheiris. Some microbiological characteristics of DGKH1 were similar to Mycoplasmas. However, the natural host and epidemiological data of DGKH1 need to be further studied.

Objective:To summarize the clinical data of Sun's procedure(total aortic arch replacement with frozen elephant trunk technique) in the treatment of complex aortic arch disease after previous cardiac surgery.Methods:From January 1, 2018 to December 31, 2020, a total of 55 patients underwent resternotomy Sun's procedure in the Aortic Surgery Center of Beijing Anzhen Hospital, including 41 males and 14 females, with a mean age of(45.4±12.7) years old, were retrospectively analyzed.
