Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Shewanella oneidensis MR-1, a Gram-negative bacterium with a significant role in the adsorption and reduction of uranium in wastewater and a quorum-sensing effect, can be used to remove uranium from wastewater. Exogenous signaling molecules (acyl-homoserine lactones, AHLs) can be added to induce the quorum sensing behavior for rapid biofilm formation, thereby improving the removal efficiency of this bacterium for uranium. Extracellular polymeric substances (EPS), as the significant components of biofilm, play a key role in biofilm formation. To investigate the quorum sensing behavior induced by AHLs, we systematically investigated the effects of AHLs on the EPS secretion and biofilm properties of S. oneidensis MR-1 by regulating parameters such as AHL species, concentration, addition time point, and contact time. The results showed that the addition of 10 μmol/L N-butyryl-l-homoserine lactone (C4-HSL) after 6 h of culture and continued incubation to reach the time point of 72 h significantly promoted the secretion of EPSs, in which the content of extracellular proteins and extracellular polysaccharides was increased by 15.2% and 28.2%, respectively, compared with that of the control group. The biofilm electrodes induced by signaling molecules showed superior properties, which were evidenced by an increase of exceeding 20 μm in biofilm thickness, an increase of 33.9% in the proportion of living cells, enhanced electroactivity, and an increase of 10.7% in the uranium removal rate. The biofilm electrode was confirmed to immobilize uranium in wastewater mainly by electrosorption, physicochemical adsorption, and electro-reduction through characterization means such as X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). This study provides a new technical idea for the efficient recovery of uranium in wastewater and enriches the theoretical system of quorum sensing regulation of electroactive biofilms.

Objective To investigate the neuroprotective effects and mechanisms of abscisic acid(ABA)in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced Parkinson's disease(PD)mouse models.Methods Eight-week-old C57BL/6J mice were randomly divided into three groups,control group(Ctrl),MPTP group,and MPTP+ABA group,12 mice in each group.Except for the control group,mice in the other groups were intraperitoneally injected with MPTP 25 mg/kg daily for 8 consecutive days to establish a subacute PD model.The MPTP+ABA group received intraperitoneal injections of ABA 25 mg/kg daily for 11 consecutive days,starting 3 days prior to MPTP administration.Behavioral tests were performed 24 hours after the last administration.On day 3,the expression of tyrosine hydroxylase(TH)and glial fibrillary acidic protein(GFAP)in the substantia nigra pars compacta(SNc)and striatum(STR)was analyzed by Western blotting,and mRNA levels of inflammatory factors were measured by Real-time PCR.Immunofluorescent staining was used to detect the expression of TH,GFAP,and ionized calcium-binding adapter molecule 1(Iba1).Results Compared with the control group,MPTP-treated mice exhibited impaired motor function,a reduced number of TH-positive dopaminergic neurons in the SNc,down-regulated TH protein expression in both the SNc and striatum,up-regulated GFAP protein expression,increased numbers of GFAP-and Iba1-positive cells,and elevated levels of pro-inflammatory factors.In contrast,the MPTP+ABA group showed improved motor function,increased TH-positive neurons in the SNc,up-regulated TH protein expression,down-regulated GFAP protein expression,reduced numbers of GFAP-and Iba1-positive cells,and decreased pro-inflammatory factor levels compared to the MPTP group.Conclusion ABA ameliorates motor dysfunction in MPTP-induced PD model mice,reduces degeneration and death of dopaminergic neurons in the SNc,suppresses the proliferation and activation of astrocytes and microglia in the SNc and striatum,and alleviates neuroinflammation.These results suggest that ABA exerts neuroprotective effects in MPTP-induced PD model mice.

Objective To investigate the effect of senkyunolide I(SEN I)on neuronal apoptosis in sepsis-associated encephalopathy(SAE)rats via modulation of the mixed-lineage kinase 3(MLK3)/c-Jun N-terminal kinase 3(JNK3)signaling pathway.Methods Screening for a SAE model by monitoring neurobehavioral and electroencephalographic alterations in rats with sepsis induced by cecal ligation and puncture(CLP).Divided into normal control group,sham operation group,sepsis without encephalopathy group,SAE model group,SAE+MLK3/JNK3 signaling pathway inhibitor(URMC-099)group,SAE+low-dose SEN I group(36 mg/kg),and SAE+high-dose SEN I group(144 mg/kg),with 10 animals in each group.After 30 minutes of successful modeling,intraperitoneal injection was administered according to the group,and the administration was completed within 24 hours.HE staining was used to observe the pathological conditions of hippocampal tissue under a light microscope,transmission electron microscopy was used to observe changes in the morphology of neuronal nuclei,cytoplasm,and mitochondrial ultrastructure,TUNEL staining was used to detect hippocampal neuronal apoptosis,and Western blotting was used to detect the expression levels of p-JNK3,JNK3,p-MLK3,MLK3,and Fas ligand(Fas-L)proteins.Results Compared with the normal control group and sham surgery group,the sepsis without encephalopathy group showed no significant changes in neuronal structural morphology and neuronal apoptosis,and there were no significant differences in the expression of p-JNK3,JNK3,p-MLK3,MLK3,and Fas-L proteins(P＞0.05).However,the SAE model group had aggravated neuronal structural morphology damage,increased neuronal apoptosis rate,and increased expression level of p-JNK3,JNK3,p-MLK3,MLK3,and Fas-L proteins(P＜0.01);Compared with the SAE model group,the inhibitor URMC-099 and SEN I treatment groups showed significant improvement in neuronal structural and morphological damage,decreased neuronal apoptosis rates,and reduced p-JNK3,JNK3,p-MLK3,MLK3,and Fas-L protein expression(P＜0.01),with the high-dose SEN I group showing more significant improvement.Conclusion SEN I effectively reduces neuronal apoptosis in SAE and exerts neuroprotective effects on SAE by inhibiting the activation of the MLK3/JNK3 signaling pathway.

OBJECTIVE: To analyze the gene mutation characteristics and survival time of patients with newly diagnosed acute myeloid leukemia (AML) based on next-generation sequencing(NGS) gene detection. METHODS: A retrospective analysis was conducted on the clinical data of 92 patients with AML (non APL) admitted to our hospital from January 2018 to May 2022. AML related genes tested were using NGS, the mutation characteristics and survival time of AML patients were analyzed. RESULTS: Among the 92 patients, 41 were males and 51 were females. A total of 38 types of gene mutations were detected. Six-two patients carried at least one gere mutation, while no gene mutations were detected in 30 patients. In the group with favourable prognosis (n =14), the frequencies of higher gene mutations were NRAS, KIT (21.43%, n =3), KRAS (14.29%, n =2). In the group with intermediate prognosis (n =64), the gene mutation frequencies from high to low were DNMT3A (18.75%, n =12), NPM1 (17.19%, n =11), IDH2, FLT3-ITD, CEBPA (12.50%, n =8), TET2 (10.94%, n =7). In the poor prognosis group (n =14), ASXL1, TP53, EZH2, NRAS had higher gene mutation frequency than others(14.29 %, n =2 ). Statistical analysis revealed that KIT had a relative hotspot of mutations in the intermediate-risk group, and DNMT3A had a relative hotspot of mutations in the high-risk group (P < 0.05). The correlation analysis of genes with high mutation rates in different prognostic groups, such as NRAS, KIT, IDH2, DNMT3A, NPM1, and FLT3-ITD, with prognosis found that KIT was a factor affecting OS (P < 0.05), while no significant differences were observed for the others(P >0.05). CONCLUSION The frequency of gene mutations is high in AML patients, 67.4% of the patients carried at least one gene mutation. The mutation frequency varies among different genes in patients with different karyotypes, and there are obvious dominant mutations. KIT and DNMT3A can be used as factors for evaluating the prognosis of AML.

The ventral anterior (VA) nucleus of the thalamus is a major target of the basal ganglia and is closely associated with the pathogenesis of Parkinson's disease (PD). Notably, the VA receives direct innervation from the hypothalamic histaminergic system. However, its role in PD remains unknown. Here, we assessed the contribution of histamine to VA neuronal activity and PD motor deficits. Functional magnetic resonance imaging showed reduced VA activity in PD patients. Optogenetic activation of VA neurons or histaminergic afferents significantly alleviated motor deficits in 6-OHDA-induced PD rats. Furthermore, histamine excited VA neurons via H1 and H2 receptors and their coupled hyperpolarization-activated cyclic nucleotide-gated channels, inward-rectifier K⁺ channels, or Ca²⁺-activated K⁺ channels. These results demonstrate that histaminergic afferents actively compensate for Parkinsonian motor deficits by biasing VA activity. These findings suggest that targeting VA histamine receptors and downstream ion channels may be a potential therapeutic strategy for PD motor dysfunction.
