Probiotics play a crucial role in colon cancer treatment by metabolizing prebiotics to generate short-chain fatty acids (SCFAs). Colon cancer patients are frequently propositioned to supplement with probiotics to enhance the conversion and utilization of prebiotics. Nevertheless, the delivery and colonization of probiotics is hindered by the harsh conditions of gastrointestinal tract (GIT). Here, we devised a straightforward yet potent modified prebiotic-based "shield" (Gelatin-Inulin, GI), employing dietary inulin and natural polymer gelatin crosslinked via hydrogen bonding for enveloping Lactobacillus reuteri (Lr) to formulate synbiotic hydrogel capsules (Lr@Gl). The GI "shield" serves as a dynamic barrier, augmenting the resistance of Lr to gastric acid and facilitating its bioactivity and adherence in the GIT, synergizing with Lr to elicit an anti-tumor effect. Simultaneously, Lr@GI demonstrates anti-tumor effects by depleting glutathione to release reactive oxygen species, accompanied by the activation of NLRP3 (NOD-like receptor family pyrin domain containing 3), and the induction M1 macrophage polarization. Furthermore, Lr@GI can not only promote the recovery of intestinal barrier but also regulate intestinal flora, promoting the production of SCFAs and further exerting anti-tumor effect. Crucially, Lr@GI also potentiates the anti-tumor effect of 5-Fluorouracil. The construction and synergistic anti-tumor mechanism of synbiotic hydrogel capsules system provide valuable insights for gut microbial tumor therapy.

OBJECTIVES: To explore the mechanism that mediate the therapeutic effect of quercetin on heart failure. METHODS: We searched the TCMSP and Swiss ADME databases for the therapeutic targets of quercetin and retrieved heart failure targets from the Genecards and OMIM databases. The intersecting targets were analyzed with GO and KEGG pathway analysis using DAVID database, and the key genes were identified via PPI analysis. Molecular docking between the core targets and quercetin was performed using PyMOL and AutoDock Tools. In a heart failure model established in H9C2 cardiomyocytes by treatment with isoproterenol, the effect of quercetin on the expressions of the MAPK signaling pathway was tested. RESULTS: A total of 60 intersecting targets were identified. Enrichment analysis revealed that quercetin may inhibit heart failure through the MAPK signaling pathway. The core genes, including AMPK3 and BCL-2, were identified as potential key regulators in quercetin-mediated improvement of heart failure. Cellular experiments demonstrated that quercetin significantly reduced isoproterenol-induced apoptosis of cardiomyocytes in a dose-dependent manner and obviously decreased the Bax/Bcl-2 ratio and the expression levels of caspase-3, ERK and p38 in the cells. CONCLUSIONS Quercetin improves heart failure possibly by inhibiting cardiomyocyte apoptosis through the MAPK signaling pathway.

OBJECTIVE: Acupuncture therapies are known for their effectiveness in treating a variety of gastric diseases, although the mechanisms underlying these effects are not fully understood. This study tested the effectiveness of electroacupuncture (EA) at acupoints Zhongwan (RN12) and Weishu (BL21) for managing gastric motility disorder (GMD) and investigated the underlying mechanisms involved. METHODS: A GMD model was used to evaluate the impact of EA on various aspects of gastric function including the amplitude of gastric motility, electrogastrogram, food intake, and the rate of gastric emptying. Immunofluorescence techniques were used to explore the activation of spinal neurons by EA, specifically examining the presence of cholera toxin B subunit (CTB)-positive neurons and fibers emanating from acupoints RN12 and BL21. The stimulation of γ-aminobutyric acid (GABA)-ergic neurons in the spinal dorsal horn, the inhibition of sympathetic preganglionic neurons in the spinal lateral horn, and their collective effects on the activity of sympathetic nerves were examined. RESULTS: EA at RN12 and BL21 significantly improved gastric motility compromised by GMD. Notably, EA activated spinal neurons, with CTB-positive neurons and fibers from RN12 and BL21 being detectable in both the dorsal root ganglia and the spinal dorsal horn. Further analysis revealed that EA at these acupoints not only stimulated GABAergic neurons in the spinal dorsal horn but also suppressed sympathetic preganglionic neurons in the spinal lateral horn, effectively reducing excessive activity of sympathetic nerves triggered by GMD. CONCLUSION EA treatment at RN12 and BL21 effectively enhances gastric motility in a GMD model. The therapeutic efficacy of this approach is attributed to the activation of spinal neurons and the modulation of the spinal GABAergic-sympathetic pathway, providing a neurobiological foundation for the role of acupuncture in treating gastric disorders.

Anemia of chronic disease (ACD) is the most frequent clinical issue in patients with chronic disease. ACD is usually secondary to chronic kidney disease (CKD), cancer, and chronic infection, which is associated with poor health outcomes, increased morbidity and mortality, and substantial economic costs. Current treatment options for ACD are very limited. The discovery of the hypoxia-inducible factor-prolyl hydroxylase (HIF-PHD) pathway made it possible to develop novel therapeutic agents (such as hypoxia-inducible factor-prolyl hydroxylase inhibitor, HIF-PHI) to treat ACD by stabilizing HIF and subsequently promoting endogenous erythropoietin (EPO) production and iron absorption and utilization. Thus, HIF-PHIs appear to open a new door for the treatment of ACD patients with a novel mechanism. Here, we comprehensively reviewed the latest advancements in the application of HIF-PHIs in ACD. Specifically, we highlighted the key features of HIF-PHIs on ACD, such as stimulation of endogenous EPO, handling iron metabolism, inflammation-independent, and prolonging lifespan of red blood cells. In conclusion, the success of HIF-PHIs in the treatment of ACD may expand the therapeutic opportunity for other types of anemia beyond renal anemia.

Objective:To investigate the clinical characteristics of sepsis-induced myocardial injury and microbial distribution.Methods:It was a retrospective observational study conducted from Jan 2023 to Dec 2023 in the Department of Emergency Intensive Care Medicine, Changshu Hospital Affiliated to Soochow University. Patients meeting the sepsis 3.0 criteria were included, excluding those with underlying cardiovascular diseases or incomplete data. Patients were categorized into myocardial injury (SIMI) and non-myocardial injury (Non-SIMI) groups based on troponin levels. General patient information, laboratory results, microbial findings, and prognostic indicators were collected. Differences in clinical parameters between the two groups were compared. Factors showing statistical differences in univariate analysis were further analyzed using multivariable logistic regression to identify risk factors for SIMI. Conduct propensity score matching among Pulmonary infection patients who underwent bronchoalveolar lavage high-throughput sequencing to compare microbial distribution between groups. Bracken was used to estimate species-level abundance from Kraken2 results, and α and β diversity analyses were conducted on the metagenomic samples.Results:A total of 179 patients were included in the study, with 98 (54.4%) in the Non-SIMI group and 81 (45.5%) in the SIMI group. There were 69 deaths overall (38.5%), with 23 (23.7%) in the Non-SIMI group and 46 (56.8%) in the SIMI group (χ 2=20.347, P<0.01). The 28-day survival curve indicated survival rates in the SIMI group were significantly lower compared to the Non-SIMI group (Log Rank χ 2=21.270, P<0.01). Univariate analysis revealed that fungal infection rate ( P=0.007), C-reactive protein ( P=0.021), procalcitonin, blood urea nitrogen, creatinine, alanine transaminase, and lactate levels were higher in the SIMI group compared to the Non-SIMI group (all P<0.01), prothrombin time was prolonger ( P<0.01) and APACHEⅡ scores were higher ( P<0.01), while serum albumin, base excess, and platelet levels were lower (all P<0.01). Multivariable logistic regression analysis indicated that fungal infection ( OR=3.441, P=0.015) was a risk factor for SIMI, whereas base excess and platelets were protective factors ( OR=0.845, 0.988, both P<0.01). Comparison of bronchoalveolar lavage high-throughput sequencing results in the pulmonary infection subgroup showed the relative abundance of Haemophilus paraininfluenzae in Non-SIMI group was higher than SIMI group among the top 20 species ( P=0.013). There were no statistically significant differences in microbial αand β-diversity between the two groups. Conclusions:The incidence of SIMI is relatively highamong sepsis patients and it affects their prognosis. Risk factors for SIMI include fungal infection, decreased platelet count, and reduced base excess levels. Among patients with pulmonary infections, there is a lower risk of SIMI associated with Haemophilus influenzae infection.

In this work,near infrared carbon quantum dots(NIR-CDs)were synthesized by hydrothermal method using biomass material Clausena lansium leaves.The synthesized NIR-CDs emitted maximum fluorescence signal at 677 nm,which was independent of excitation wavelength.The characterization results showed that there were abundant groups on the surface of NIR-CDs.Pd2+could form non-fluorescent compounds with the surface groups of NIR-CDs,resulting in fluorescence quenching(Fluorescence signal was denoted as F0).Because chlorpromazine hydrochloride(CPZ)parent nucleus contained unoxidized S atom,CPZ could form stable colored complex with Pd2+under acidic conditions.In the presence of CPZ,Pd2+dissociated from the surface of NIR-CDs and bonded with CPZ,so that the fluorescence signal could be restored(Fluorescence signal was denoted as F).An"on-off-on"fluorescence sensor was thus constructed.The fluorescence signal recovery value of NIR-CDs(△F=F-F0)showed a good linear relationship with the concentration of CPZ in the range of 5.68-28.43 μg/mL,and the detection limit(3σ)was 0.078 μg/mL.The sensor was applied to determination of CPZ in pharmaceutical preparations,and the recoveries were 94％-106％.The developed fluorescence sensor was expected to be used in quality control of actual pharmaceutical preparations.

Objectives:To analyze the correlation between cervical spine postures and different types of odontoid fractures when injured in different directions of violence using finite element method.Methods:Based on the experience of establishing the finite element model of the upper cervical vertebrae in the early stage,and verified as effective through literature published abroad and in vitro experiments,different positions of the cervical spine(neutral position,flexion position,extension position,lateral bending position,and rotation position)were preset on the established three-dimensional nonlinear finite element model of the normal occip-ital-atlantoaxial complex,and an acceleration of 8m/s2 was applied in each direction of violence[anterior,pos-terior,lateral,top(vertical downward)].The von Mises stress values in different regions of different types(An-derson and D'Alonzo type)of odontoid process fractures were calculated,and stress contour maps were ex-tracted.Results:When subjected to anterior violence,the maximum von Mises stress values were generated in an extension position,with stress concentration in the vertebral body of the axis(Type Ⅲ)(0.41MPa).When subjected to posterior violence,the maximum von Mises stress values were generated when the cervical vertebrae were in a flexion position,with stress concentration in the odontoid process base(Type Ⅱ)(0.52MPa)and the vertebral body of the axis(Type Ⅲ)(0.55MPa).When subjected to lateral violence,the maximum von Mises stress values were generated when the cervical vertebrae were in a flexion position,with stress concen-tration in the odontoid process base(Type Ⅱ)(0.51MPa)and the vertebral body of the axis(Type Ⅲ)(0.43MPa).When subjected to vertical downward violence,the stress values in each body position increased significantly,the stress at the tip of the odontoid process(Type Ⅰ)in the flexion position reached 0.99MPa,the stress at the base of the odontoid process(Type Ⅱ)in the lateral flexion position reached 1.16MPa,and the stress at the axis vertebral body(Type Ⅲ)in the rotational position was 0.85MPa.Conclusions:When the upper cervi-cal spine is in a flexion position and receives a vertically downward force,it is prone to odontoid process tip fractures(Type Ⅰ);When the upper cervical spine is in a flexion position and receives a posterior or lateral force,or when it is in a lateral bending position and receives a vertically downward force,it is prone to odontoid process base fractures(Type Ⅱ);When the upper cervical spine is in a flexion position and receives a posterior force,or when it is in a rotational position and receives a vertically downward force,it is prone to axis vertebral body fractures(Type Ⅲ).

Objective To compare the efficacy and safety of gemcitabine combined with conventional-dose cisplatin(70 mg/m2,day 2)versus split-dose cisplatin(35 mg/m2,days 1 and 8)in neo-adjuvant therapy for muscle-invasive bladder cancer(MIBC).Methods The clinical data of 33 MIBC patients receiving(gemcitabine+cisplatin,GC)-based neoadjuvant chemotherapy in the Department of Urology of Xinhua Hospital,during Jan.2021 and Aug.2024 were retrospectively analyzed,including 18(54.5％)patients treated with a conventional-dose regimen(GC group),and 15(45.5％)patients treated with a split-dose regimen(GCs group).The efficacy endpoints and incidence/severity of adverse reactions were compared between the two groups.Results Baseline characteristics were well-balanced between the two groups(P＞0.05).No significant differences were observed in the complete response rate(CR:33.3％vs.22.2％),objective response rate(ORR:66.7％vs.61.1％),or disease control rate(DCR:80.0％vs.88.9％)between the GCs and GC groups(P＞0.05).The GCs group exhibited a significantly lower incidence of chemotherapy-related renal injury(6.7％vs.38.9％,P＜0.05),while the occurrence of other adverse events was comparable between the two groups.Notably,the GCs group demonstrated significantly attenuated nephrotoxicity,as evidenced by markedly smaller changes in estimated glomerular filtration rate[eGFR:(4.5±4.7)％vs.(18.0±11.8)％]and serum creatinine[SCr:(5.7±5.6)％vs.(20.2±19.5)％]compared to the GC group(P＜0.05).Conclusion Compared with the conventional-dose regimen,the split-dose regimen maintains equivalent clinical efficacy of GC-based neoadjuvant chemotherapy while significantly reducing chemotherapy-related nephrotoxicity,thereby providing MIBC patients with a safer therapeutic option.

The renin-angiotensin-aldosterone system (RAAS) is crucial for regulating blood pressure and maintaining fluid balance, while clock genes are essential for sustaining biological rhythms and regulating metabolism. There exists a complex interplay between RAAS and clock genes that may significantly contribute to the development of various cardiovascular and metabolic diseases. Although current literature has identified correlations between these two systems, the specific mechanisms of their interaction remain unclear. Moreover, the interaction patterns under different physiological and pathological conditions need further investigation. This review summarizes the synergistic roles of the RAAS and clock genes in cardiovascular diseases, explores their molecular mechanisms and pathophysiological connections, discusses the application of chronotherapy, and highlights potential future research directions, aiming to provide novel insights for the prevention and treatment of related diseases.

OBJECTIVE: To observe the clinical symptoms and MRI outcomes of patients with ruptured lumbar disc herniation(LDH) through a multicenter randomized controlled study, and to evaluate the clinical efficacy and safety of Yiqi Huoxue formula() in the treatment of this disease. METHODS: A total of 160 outpatients and inpatients with ruptured LDH admitted to 4 medical centers from January 2023 to June 2023 were selected and randomly divided into the Yiqi Huoxue formula group and the control group, with 80 patients in each group. In the Yiqi Huoxue formula group, there were 43 males and 37 females, with an age of (41.03±9.56) years and a disease duration of (10.45±25.37) days, and the patients were treated with Yiqi Huoxue formula. In the control group, there were 34 males and 46 females, with an age of (42.14±8.73) years and a disease duration of (11.31±21.14) days;during the acute phase, patients in this group could take celecoxib capsules orally, and methylcobalamin orally at the same time. The Japanese Orthopaedic Association (JOA) score, Oswestry disability index (ODI), changes in the volume of herniated disc tissue on MRI, herniation rate, and absorption rate were recorded at the time of enrollment and during follow-ups at the 3rd, 6th, and 12th month after treatment. RESULTS: A total of 156 patients completed the clinical follow-up, and 4 patients withdrew midway. The clinical symptoms of all patients who completed the study were relieved to varying degrees, and reabsorption of herniated disc tissue was observed in all patients in the Yiqi Huoxue formula group after treatment. For the JOA score:in the Yiqi Huoxue formula group, it was (10.73±2.76) points before treatment and (24.65±2.19) points at the 12th month after treatment;in the control group, it was (11.01±1.20) points before treatment and (17.07±3.26) points at the 12th month after treatment. For the ODI score:in the Yiqi Huoxue formula group, it was (26.21±3.55) points before treatment and (5.65±2.19) points at the 12th month after treatment;in the control group, it was (27.92±2.51) points before treatment and (9.09±2.15) points at the 12th month after treatment. At the 12th month after treatment, the JOA and ODI scores of both groups were better than those before treatment, and the scores of the Yiqi Huoxue formula group were better than those of the control group, with statistically significant differences (P<0.05). In terms of the herniated disc volume and herniation rate on MRI, the Yiqi Huoxue formula group was superior to the control group, with statistically significant differences(P<0.05). Reabsorption occurred in 56.96%(45/79) of patients in the Yiqi Huoxue formula group, which was significantly higher than the 37.66%(29/77) in the control group. CONCLUSION After treatment with Yiqi Huoxue formula, patients with ruptured LDH show significant improvement in clinical symptoms and a marked reduction in the volume of herniated discs. During the follow-up period, no obvious adverse drug reactions are observed in patients, and no recurrence of symptoms is found at the last follow-up, indicating that the formula has safe and reliable efficacy.
