ObjectiveTo investigate the effects of Ditantang on metabolic dysfunction-associated fatty liver disease (MAFLD) in rats by focusing on the regulation of glycogen synthesis mediated by the uridine diphosphate glucose (UDPG)-site-1-protease (S1P)-sterol regulatory element-binding protein (SREBP) axis. MethodsMAFLD was modeled in SD rats by feeding a high-fat diet for 12 weeks. Rats were randomized into a control group, a model group, low-, medium-, and high-dose (2.68, 5.36, and 10.72 g·kg-1·d-1, respectively) Ditantang groups, and a positive control (Yishanfu, 0.18 g·kg-1·d-1) group. Starting from week 9 of modeling, each treatment group received corresponding drug interventions via gavage. After the experiment, the serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured. The levels of TG, non-esterified fatty acids (NEFA), glycogen, glucose-6-phosphate (G6P), glucose-1-phosphate (G1P), and UDPG in the liver tissue samples were measured by biochemical assay kits. Liver pathological morphology and lipid/glycogen deposition were observed via hematoxylin-eosin (HE) staining, oil red O staining, and Periodic acid-Schiff (PAS) staining. Immunofluorescence assay was conducted to detect the expression and localization of phosphoglucomutase-1 (Pgm1) and UDP-glucose pyrophosphorylase 2 (Ugp2) in the rat liver. Real-time PCR and Western blot were employed to quantify mRNA and protein levels, respectively, of key glycogen synthesis enzymes (Pgm1 and Ugp2), key lipogenesis-related transcription factor SREBP and its target genes [acetyl-CoA carboxylase (ACC), fatty acid synthetase (FASN), and stearoyl-CoA desaturase (SCD1)], as well as S1P. ResultsCompared with the control group, the model group exhibited elevated levels of TC, TG, LDL-C in the serum and TG and NEFA in the liver, decreased serum HDL-C level (P<0.01), reduced hepatic levels of G1P, G6P, UDPG, and glycogen (P<0.01), appearance of fat vacuoles of varying sizes and abundant red lipid droplets, with prominent lipid deposition and reduced areas of deep glycogen staining in the liver tissue, upregulated mRNA and protein levels of SREBP1, S1P, ACC, FASN, and SCD1 (P<0.01), and downregulated mRNA and protein levels of Pgm1 and Ugp2 (P<0.01). Compared with the model group, all doses of Ditantang reduced the levels of TC and TG in the serum and TG and NEFA in the liver, while elevating the serum HDL-C level. Additionally, medium- and high-dose Ditantang reducted the LDL-C level (P<0.05). Ditantang at all doses increased the hepatic levels of G1P, G6P, UDPG, and glycogen, alleviated hepatic steatosis and lipid deposition, enhanced glycogen storage, downregulated the mRNA and protein levels of SREBP1, S1P, ACC, FASN, and SCD1 (P<0.05), while upregulating the expression of Pgm1 and Ugp2 (P<0.01). Immunofluorescence analysis revealed decreased fluorescence intensity of S1P and enhanced fluorescence intensity of Ugp2 (P<0.01). ConclusionDitantang can regulate glycogen synthesis through the UDPG-S1P-SREBP axis to prevent and treat MAFLD.

ObjectiveTo investigate the effects of modified Ditan tang on genes related to the transcription-translation feedback loop (TTFL) of biorhythm in the rat model of non-alcoholic fatty liver disease (NAFLD) and its mechanism for prevention and treatment of NAFLD. MethodsSixty-five healthy SPF male SD rats were randomly assigned into blank (n=20), model (n=15), and low-, medium-, and high-dose (2.68, 5.36, and 10.72 g·kg-1·d-1, respectively) modified Ditan tang (n=10) groups. Other groups except the blank group were fed a high-fat diet for 12 weeks. The modified Ditan tang groups were treated with the decoction at corresponding doses by gavage, and the blank and model groups were treated with an equal volume of normal saline from the 9th week for 4 weeks. The levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in the serum were measured by an automatic biochemical analyzer. TG and non-esterified fatty acid (NEFA) assay kits were used to measure the levels of TG and NEFA in the liver. The pathological changes in the hypothalamus and liver were observed by hematoxylin-eosin staining, and the lipid deposition in the liver was observed by oil red O staining. The levels of brain-muscle ARNT-like protein 1 (BMAL1/ARNTL) in the hypothalamus and liver were determined by immunohistochemical staining. The mRNA and protein levels of BMAL1, circadian locomotor output cycles kaput (CLOCK), period circadian clock 2 (PER2), and cryptochrome1 (Cry1) in the hypothalamus and liver were determined by Real-time PCR and Western blot, respectively. ResultsCompared with the blank group, the model group showed elevated levels of TG, TC, LDL-C, AST, and ALT (P<0.01) and a lowered level of HDL-C (P<0.05) in the serum, elevated levels of TG and NEFA in the liver (P<0.01), pyknosis and deep staining of hypothalamic neuron cells, and a large number of vacuoles in the brain area. In addition, the model group showed lipid deposition in the liver, up-regulated mRNA and protein levels of CLOCK and BMAL1 (P<0.01), and down-regulated mRNA and protein levels of Cry1 and PER2 (P<0.01) in the hypothalamus and liver. Compared with the model group, all the three modified Ditan tang groups showed lowered levels of TG, TC, LDL-C, ALT, and AST (P<0.05, P<0.01) and an elevated level of HDL-C (P<0.05) in the serum, and lowered levels of TG and NEFA (P<0.05, P<0.01) in the liver. Furthermore, the three groups showed alleviated pyknosis and deep staining of hypothalamic neuron cells, reduced lipid deposition in the liver, down-regulated mRNA and protein levels of CLOCK and BMAL1 (P<0.05, P<0.01), and up-regulated mRNA and protein levels of Cry1 and PER2 (P<0.05, P<0.01) in the hypothalamus and liver. ConclusionModified Ditan tang can reduce lipid deposition in the liver and regulate the expression of CLOCK, BMAL1, Cry1, and PER2 in the TTFL of NAFLD rats.

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.

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.

ObjectiveTo explore the effect of gypenosides (GPs) on liver lipid deposition in metabolism-associated fatty liver disease (MAFLD) mice and its mechanism based on classical/non-classical ferroptosis. MethodsEight male C57BL/6 mice in a blank group and 32 male apolipoprotein E gene knockout (ApoE-/-) mice were randomly divided into a model group, a low-dose GPs (GPs-L) group, a high-dose GPs (GPs-H) group, and a simvastatin (SV) group. Starting from the second week, mice in the blank group were given a maintenance diet, and the other four groups were fed a high-fat diet daily. After eight weeks of feeding, mice in the GPs-L and GPs-H groups were given GPs of 1.487 mg·kg-1·d-1 and 2.973 mg·kg-1·d-1, respectively, and mice in the SV group were given simvastatin of 2.275 mg·kg-1·d-1. Mice in the blank group and the model group were given saline of equal volume by gavage for four weeks. The content of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in the serum of mice in each group was detected by an automatic biochemical analyzer. The level of non-esterified fatty acid (NEFA) and TG in the mouse liver was measured by the kit. The change in liver tissue structure and lipid deposition was observed by hematoxylin-eosin (HE) and oil red O staining. The levels of coenzyme Q10 (CoQ10), glutathione (GSH), malondialdehyde (MDA), and Fe2+ in serum, as well as nicotinamide adenine dinucleotide phosphate [NAD(P)H] in the liver were detected by enzyme-linked immunosorbent assay (ELISA). The expression of ferroptosis suppressor protein 1 (FSP1) in the liver of mice was observed by the immunohistochemical (IHC) method, and the expression of genes and proteins related to classical and non-classical ferroptosis pathways was analyzed by real-time polymerase chain reaction (Real-time PCR) and Wes automated protein expression analysis system. ResultsCompared with those in the blank group, the levels of TC, TG, LDL-C, ALT, and AST in serum and TG and NEFA in the liver in the model group were significantly increased, and the level of HDL-C in serum was significantly decreased (P<0.01). The liver tissue structure changed, and there were fat vacuoles of different sizes and a large number of red lipid droplets, with obvious lipid deposition. The level of CoQ10 and GSH in serum and NADH in the liver were significantly decreased, while the level of MDA and Fe2+ in serum was significantly increased (P<0.01). The mRNA and protein expressions of cystine/glutamate transporter (xCT/SLC7A11), glutathione peroxidase (GPX4), p62, nuclear factor E2-related factor 2 (Nrf2), and FSP1 were significantly decreased, and the mRNA and protein expressions of tumor antigen (p53), spermidine/spermine N1-acetyltransferase 1 (SAT1), arachidonate 15-lipoxygenase (ALOX15), and Kelch-like epichlorohydrin-associated protein-1 (Keap1) were significantly increased (P<0.01). Compared with those in the model group, the level of TC, TG, LDL-C, ALT, and AST in serum and TG and NEFA in the liver of mice in the GPs-L, GPs-H, and SV groups were decreased, while the level of HDL-C in serum was significantly increased (P<0.05, P<0.01). The liver tissue structure and lipid deposition were improved. The levels of CoQ10 and GSH in serum and NADH in the liver were significantly increased, while the levels of MDA and Fe2+ in serum were significantly decreased (P<0.05, P<0.01). The mRNA and protein expressions of xCT, GPX4, p62, Nrf2, and FSP1 were significantly increased, while the mRNA and protein expressions of p53, SAT1, ALOX15, and Keap1 were significantly decreased (P<0.05, P<0.01). ConclusionGPs can interfere with liver lipid deposition in MAFLD mice through classical/non-classical ferroptosis pathways.

BackgroundGraduate students frequently face life events, many of which may adversely affect their mental well-being. However, the interaction between life events and the development of depression, anxiety, and somatic symptoms remains unclear. ObjectiveTo explore the relationship between life events and the development of depressive, anxiety and somatic symptoms in graduate students, thereby informing prevention strategies for these conditions. MethodsA sample of 6 722 newly enrolled graduate students at a comprehensive university in Southwest China from September to November 2018 was selected. The assessment was conducted using the Adolescent Self-rating Life Events Checklist (ASLEC), the 7-item Generalized Anxiety Disorder scale-7 item (GAD-7), the Patient Health Questionnaire Depression Scale-9 item (PHQ-9), and the Patient Health Questionnaire-15 (PHQ-15). Network analysis was implemented by using the bootnet and qgraph packages in the R software (version 4.2.3), with centrality indices calculated to identify core and bridge symptoms within the network. ResultsThe study encompassed a total of 6 171 graduate students, representing 91.80% of the target population. The prevalence rates of anxiety, depressive, and somatic symptoms among graduate students were 12.59% (777/6 171), 16.63% (1 026/6 171), and 27.66% (1 707/6 171), respectively. Network analysis revealed that 'academic stress' was the core symptom with the highest strength and expected influence (both values=1.207), while 'feeling down, depressed, or hopeless' was the bridge symptom with the highest bridge strength and bridge expected influence (both values=0.454). There was no significant difference in global network strength and edge weight between women and men (P>0.05). ConclusionAcademic stress, emerging as the core symptom, assumes a dominant position within the symptom network and exhibits strong interactions with other negative affective states. There was no gender difference in the network structure.

Background and Aims:Abdominal aortic aneurysm(AAA)is a common arterial dilation disease in vascular surgery,with aneurysm rupture being its most serious complication,often leading to fatal hemorrhage and posing a severe threat to patients'lives.Endovascular aneurysm repair(EVAR),due to its minimally invasive nature,safety,and rapid recovery,has become the preferred treatment for AAA.However,endoleak,a complication unique to EVAR,remains a major clinical challenge.Persistent endoleak can lead to sustained high pressure within the aneurysm sac,increasing the risk of continued expansion and rupture.It is one of the main causes of the high reintervention rate following EVAR.In particular,the treatment strategy for type Ⅱ endoleaks remains controversial.This study was conducted to evaluate the clinical value of selective sac embolization via the iliac approach combined with standard EVAR in managing intraoperative immediate endoleaks.Methods:The clinical data of AAA patients with a risk of endoleak who underwent standard EVAR at the First Hospital of China Medical University between March 2023 and September 2024 were retrospectively collected.Patients were divided into an intervention group(n=42)and a non-intervention group(n=32)based on whether selective sac embolization via the iliac approach was performed during operation.General clinical data,preoperative anatomical characteristics of the AAA,surgical details,and postoperative follow-up results were compared between the two groups.Results:There were no statistically significant differences between the two groups in terms of age,sex,anatomical features,rupture rate,or off-label use(all P>0.05).The technical success rate during surgery was 100%in both groups.One patient in the intervention group experienced transient sigmoid colon ischemia after operation,which resolved with conservative treatment.The mean follow-up period was(6.49±4.68)months.The proportions of aneurysm sac shrinkage,stability,and enlargement in the intervention group were 40.5%,57.1%,and 2.4%,respectively,compared to 59.4%,40.6%,and 0.0%in the non-intervention group,with no statistically significant differences(all P>0.05).The incidence of endoleak during follow-up was also comparable between the two groups(P>0.05).Conclusion:For intraoperative endoleaks during standard EVAR,selective sac embolization via the iliac approach is a technically simple and safe method that provides short-term outcomes comparable to those in patients without intraoperative endoleaks.Its long-term efficacy warrants further investigation through extended follow-up.

Objective:To explore the clinical efficacy and safety of unilateral biportal endoscopic (UBE) and percutaneous transforaminal endoscopic discectomy (PTED) techniques in treating recurrent lumbar disc herniation (RLDH).Methods:This study is a retrospective cohort study. The clinical data were retrospectively collected from 68 patients who underwent surgical treatment for RLDH at Department of Mini-invasive Spinal Surgery, the Third People′s Hospital of Henan Province from June 2020 to June 2023. The patients were divided into the UBE group (38 cases) and the PTED group (30 cases) based on the surgical technique used. The drainage volume, surgery duration, and postoperative complications for revision surgeries in both groups were recorded. Visual analogue scale(VAS) and Oswestry disability index (ODI) were used to assess back pain and leg pain degrees and improvements preoperatively, 3 days postoperatively, 3 months postoperatively, and at the final follow-up. The modified Macnab criteria were used to evaluate outcomes at the final follow-up. The data comparison was conducted using independent sample t-test, repeated measures analysis of variance, χ2 test or Fisher's exact test. Results:All surgeries were successfully completed. The surgery duration in the UBE group was significantly shorter than in the PTED group, with statistically significant differences ((50.9±10.5)minutes vs.(55.9±12.5)minutes, t=1.234, P=0.001). All patients were followed up for more than 1 year, with a follow-up period of (18.1±5.6) months (range: 12 to 29 months). Both groups showed a significant reduction in VAS and ODI for back and leg pain at all postoperative time points compared to preoperative scores (all P<0.05). However, there were no statistically significant differences in VAS of low back pain, lower limb pain score and ODI score over time between the groups (all P>0.05). At the final follow-up, the UBE group had an excellent and good rate of 92.1% (35/38); the PTED group had an excellent and good rate of 86.6% (26/30)( χ2=0.727, P=0.867). One patient in the UBE group and three in the PTED group experienced cerebrospinal fluid leaks, and one patient in the PTED group experienced postoperative leg numbness; all were discharged after conservative treatment. At the final follow-up, lumbar X-rays, CT, and MRI evaluations showed no recurrence or instability at the surgical segments. Conclusions:Both UBE and PTED can achieve good clinical outcomes in the treatment of RLDH through continuous visualization. The choice of surgical method for RLDH should be more precisely tailored to the individual.
