Functional dyspepsia （FD） is a prioritized disease category where traditional Chinese medicine （TCM） demonstrates distinct therapeutic advantages. The current western medicine treatment for FD is mainly based on proton pump inhibitors and prokinetic agents， with digestive enzymes， probiotics and antidepressants serving as adjuvant medication， yet such therapies still have certain limitations. TCM treatment for FD includes oral administration of Chinese herbal formulas and Chinese patent medicines， as well as external TCM therapies such as acupuncture and moxibustion， acupoint application， hot medicinal compress therapy， rubbing with ointment， medicinal iontophoresis， auricular acupoint therapy and tui na （Chinese medical massage）. The combined treatment of FD with integrated TCM and western medicine can significantly improve clinical effectiveness and reduce adverse reactions. The common mechanisms underlying the therapeutic effects of both TCM and western medicine revolve around the core pathological processes of FD， mainly focusing on restoring gastrointestinal motility， regulating the levels of brain-gut peptides， modulating intestinal microecology， and ameliorating inflammatory status. The differential mechanisms lie in the precise targeting feature of western medicine versus the holistic-regulating and multi-target characteristics of TCM， and the two approaches exert a synergistic effect to enhance efficacy. This paper proposes to leverage the advantages of TCM in holistic regulation and the strengths of western medicine in targeted treatment， so as to provide personalized and comprehensive treatment regimens for FD patients.

Objective To explore the clinical characteristics and related prognostic factors of hypertriglyceridemia acute pancreatitis (HTG-AP). Methods A retrospective analysis was conducted on 350 patients with HTG-AP admitted to HanZhong Central Hospital from March 2019 to March 2024. All patients received conventional treatment. They were followed up for one year after treatment. The prognosis of the patients was statistically analyzed, and logistic regression was used to analyze the related factors of prognosis. Results HTG-AP patients had an acute onset, with clinical symptoms of sudden upper abdominal pain (329/350), nausea and vomiting (275/350), acidosis (101/350), and multiple organ failure (38/350). All patients had elevated serum TG. During the follow-up period, 123 cases had a poor prognosis (poor prognosis group), and 227 cases had a good prognosis (good prognosis group). Compared with the good prognosis group, the patients in the poor prognosis group had higher levels of TG, creatinine and C-reactive protein at admission, lower levels of serum calcium and albumin, and higher proportions of diabetes mellitus history and severe conditions (P<0.05). Logistic regression analysis found that the factors related to the prognosis of patients with HTG-AP were TG level, C-reactive protein level, albumin level, history of diabetes mellitus, and moderate to severe condition (P<0.05). Conclusion HTG-AP patients have an acute onset and have main clinical symptoms of sudden upper abdominal pain, nausea and vomiting. Some patients experience systemic inflammatory reactions such as acidosis and multiple organ failure, and they may also have significantly increased serum TG. TG, C-reactive protein, albumin, history of diabetes mellitus, and severe disease conditions are associated with the prognosis of HTG-AP patients.

Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

ObjectiveTo investigate the ability of clinically isolated， Helicobacter pylori （H. pylori）-specific gene polymerase chain reaction （PCR）-positive gastric， vaginal， and fecal Candida to release H. pylori. MethodsResuscitate 4 strains of H. pylori -specific 16S rDNA and ureA gene PCR-positive Candida strains isolated in laboratory from clinical sources， including 1 strain of gastric Candida， 1 strain of fecal Candida， 2 strains of vaginal Candida and the standard Candida albicans strain ATCC10231 （Ca10231）. The presence of H. pylori-specific ureA in the 5 strains of Candida isolates was confirmed by PCR. The aforementioned strains of Candida and H.pylori were inoculated into urea medium and cultured in a constant temperature incubator at 37 ℃. The color change of the medium was observed daily. A change in the medium's color from yellow to red indicated the presence of urease activity. Then， the five strains of Candida and H. pylori were co-incubated with the magnetic beads coated with H. pylori antibodies respectively. Scanning electron microscopy （SEM） was employed to observe the presence of bacilli adsorbed on the surface of the magnetic beads. PCR was used to detect the presence of H.pylori-specific 16S rDNA and ureA genes on magnetic beads. ResultsThe PCR analysis of the ureA gene in the four Candida isolates was positive， whereas the Ca10231 strain tested negative. Upon culturing the four Candida isolates on urea medium， the medium color changed from yellow to red which was determined to be urease positive， while the medium containing Ca10231 remained unchanged， which was urease negative. SEM revealed that bacilli could be observed on the surface of magnetic beads co-incubated with the 4 strains of Candida of clinical origin and H.pylori isolate. Specifically， PCR testing of the magnetic beads co-incubated with one vaginal Candida， one gastric Candida and H.pylori isolate showed positive results for the 16S rDNA and ureA genes of H. pylori； however， the PCR tests for the two genes were negative for the magnetic beads co-incubated with the other two Candida isolate. ConclusionThis study demonstrates that H. pylori-specific genes Candida can release H. pylori.

The second victim phenomenon represents a pervasive yet long-overlooked occupational trauma in medical adverse events. Since the introduction of the "second victim" concept, international research has accumulated substantial theoretical and practical experience. However, China started late in this field and still faces multiple challenges, including cognitive biases, institutional deficiencies, and resource constraints. This article systematically reviews the conceptual evolution of the second victim, the phased model of psychological recovery, and its multidimensional impacts, while thoroughly analyzing the unique contributing factors of this phenomenon within China's healthcare context. On this basis, and drawing on international experience, we propose a "three-tier precision support system" tailored to China's local circumstances—encompassing universal prevention, selective intervention, and targeted treatment—and construct implementation pathways and safeguarding mechanisms across three dimensions: policy support, institutional implementation, and individual capacity building. This framework is intended to serve as a reference for establishing a localized support system that balances patient safety with the well-being of healthcare professionals.

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.

ObjectivePhotoacoustic pump-probe imaging can effectively eliminate the interference of blood background signal in traditional photoacoustic imaging, and realize the imaging of weak phosphorescence molecules and their triplet lifetimes in deep tissues. However, background differential noise in photoacoustic pump-probe imaging often leads to large fitting results of phosphorescent molecule concentration and triplet lifetime. Therefore, this paper proposes a novel triplet lifetime fitting method for photoacoustic pump-probe imaging. By extracting the phase of the triplet differential signal and the background noise, the fitting bias caused by the background noise can be effectively corrected. MethodsThe advantages and feasibility of the proposed algorithm are verified by numerical simulation, phantom and in vivo experiments, respectively. ResultsIn the numerical simulation, under the condition of noise intensity being 10% of the signal amplitude, the new method can optimize the fitting deviation from 48.5% to about 5%, and has a higher exclusion coefficient (0.88>0.79), which greatly improves the fitting accuracy. The high specificity imaging ability of photoacoustic pump imaging for phosphorescent molecules has been demonstrated by phantom experiments. In vivo experiments have verified the feasibility of the new fitting method proposed in this paper for fitting phosphoometric lifetime to monitor oxygen partial pressure content during photodynamic therapy of tumors in nude mice. ConclusionThis work will play an important role in promoting the application of photoacoustic pump-probe imaging in biomedicine.

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.

Objective To compare the effects of upper limb remote ischemic preconditioning(RIPC)with different pressure modes on enhancing high-altitude acclimatization in healthy adult males rapidly exposed to high-altitude environments.Methods In May 2024,86 male adult residents living plain areas planning a high-altitude travel were recruited through advertisements in Chongqing by Department of Anesthesiology at the Second Affiliated Hospital of Army Medical University.The participants were randomly divided into a variable pressure training group(n=29),a constant pressure training group(n=29),and a control group(n=28).The variable pressure training group underwent RIPC training in a variable pressure mode[occlusion pressure was set at systolic blood pressure(SBP)+40 mmHg],while the constant pressure training group received RIPC training in a constant pressure mode(fixed occlusion pressure of 200 mmHg).Both groups completed a bilateral upper limb RIPC training(twice daily,5 cycles per time of 10-min occlusion followed by 5-min reperfusion)for 14 d.The control group received no such training.On the 3rd day post-training,all participants entered a simulated 4 500 m altitude chamber for 7 h.The incidence and severity of acute mountain sickness(AMS)were observed and evaluated,and the vital signs and cerebral tissue oxygenation index(CTOI)were recorded.Results The incidence of AMS was 23.1%in the variable pressure training group(RR=0.4,95%CI:0.2～0.8,Chi-square=9.433,P=0.002)and 16.0%in the constant pressure training group(RR=0.2,95%CI:0.1～0.6,Chi-square=12.833,P<0.001),and both incidences were significantly lower than that in the control group(65.4%).The AMS symptom score in the variable pressure training group[1.5(0.8,3.0)vs(3.1±1.9),P=0.018]and the score in the constant pressure training group[1.0(1.0,2.0)vs(3.1±1.9),P=0.001]were significantly lower than that in the control group.The dizziness score was obviously lower in the variable pressure training group[0(0,1.0)vs 1.0(1.0,1.0),P=0.001]and the constant pressure training group[1.0(0,1.0)vs 1.0(1.0,1.0),P=0.003]than the control group,so was the fatigue/weakness score in the variable pressure training group[0(0,0.3)vs 1.0(0,1.0),P=0.006],the constant pressure training group[0 vs 1.0(0,1.0),P<0.001],and the control group.The change of CTOI(ΔCTOI)in the variable pressure training group(P=0.010)and the constant pressure training group(P=0.042)was significantly lower than that in the control group.There were no statistical differences in the 3 groups in terms of SpO2,HR,SBP or DBP(P>0.05).What's more,no significant differences were observed in the incidence of AMS,AMS score,dizziness score,fatigue/weakness score,or ΔCTOI between the variable pressure training group and the constant pressure training group(P>0.05).Conclusion Both upper limb RIPC protocols,variable-pressure(SBP+40 mmHg)and fixed-pressure(200 mmHg),can effectively enhance high-altitude acclimatization by reducing AMS incidence,symptom severity,and cerebral oxygen desaturation.
