Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription （BSTDP）. MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-LIT-Orbitrap-MS）. Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction （PPI） network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg （mpx： GFP）. At three days post-fertilization （3 dpf）， larvae of zebrafish were randomly assigned to blank group， model group， positive drug dexamethasone acetate group （75 μmol·L^-1）， and BSTDP groups with low， medium， and high doses （500， 1 000， and 2 000 mg·L^-1）. The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor kappa-B （NF-κB） signaling pathway and inflammatory factors including interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsA total of 120 chemical components were identified in BSTDP， among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis （RA） and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine， vomicine， sinapine， rehmannioside， cinnamyl alcohol glycoside， and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 （Akt1）， signal transducer and activator of transcription 3 （STAT3）， tumor necrosis factor （TNF）， TLR4， mitogen-activated protein kinase 14 （MAPK14）， and phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit α （PIK3CA）， thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L^-1. Compared to those in the blank group， zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region （P<0.01） and rising mRNA levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β （P<0.01）. Compared to that in the model group， the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses， as well as the dexamethasone acetate group （P<0.05， P<0.01）. There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β were significantly down-regulated （P<0.05， P<0.01）. ConclusionThis paper identifies the material basis of the efficacy of BSTDP， demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

Objective:To learn about the current situation of organizational management and inter-departmental coordination and provide a basis for optimization the national joint prevention and control strategy of endemic fluorosis and arsenicosis.Methods:The staff engaged in prevention and control of endemic fluorosis and arsenicosis at the provincial, municipal, county, township, and village levels were selected as the investigation subjects. An online questionnaire survey was conducted to collect relevant information on organizational management and departmental coordination. SAS 9.4 software was used for data statistical analysis.Results:A total of 3 107 valid questionnaires were collected, covering 25 provinces, distributed in 6 regions including Northeast China, North China, East China, Central China, Northwest China, and Southwest China. Totally 92.52% (1 088/1 176) of the respondents believed that a leading group for prevention and control of endemic diseases had been established in their localities, there were statistically significant differences among different regions (χ 2 = 17.18, P = 0.004). However, the highest proportion of those who believed that no leading group had been established was in the Southwest China (14.09%, 21/149). Totally 83.97% (906/1 079) of the respondents believed that the coordination role of the leading group for endemic disease prevention and control was very good or relatively good. The proportion of survey respondents who believed that the local water resources department had a good/relatively good main responsibility in implementation of water improvement measures in drinking-water-borne fluorosis and arsenic poisoning areas, as well as in management of fluoride and arsenic reduction water improvement projects, were 90.51% (2 203/2 434) and 89.37% (2 143/2 398), respectively. The differences between different regions were statistically significant (χ 2 = 70.90, 57.40, P < 0.001). The highest proportion of general/poor cases was believed to be in the southwest region [25.14% (46/183), 24.58% (44/179)]. Totally 71.37% (187/262) of the respondents believed that the supply and distribution of low-fluorine brick tea in tea-drinking-borne endemic fluorosis areas were very good or good. Totally 90.55% (1 447/1 598) of the respondents believed that local medical insurance departments had included skeletal fluorosis patients who were covered by medical insurance. Totally 90.71% (1 474/1 625) of the respondents believed that social assistance departments had included eligible patients with skeletal fluorosis in the scope of social assistance. There were significant differences in the inclusion rate among different regions (χ 2 = 50.45, 46.22, P < 0.001). North China [18.99% (30/158), 21.43% (33/154)] and Southwest China [18.64% (33/177), 15.22% (28/184)] were the two regions with the highest percentage of respondents who believed that the above two were not included. Totally 83.19% (1 425/1 713) of the respondents believed that the local designated hospital for treatment of skeletal fluorosis had been established, there were statistically significant differences among different regions (χ 2 = 31.54, P < 0.001). North China (26.40%, 47/178) and Northwest China (24.56%, 42/171) had the highest proportion of those who believed that there were no designated treatment hospitals for skeletal fluorosis. Totally 83.58% (1 502/1 797) of the respondents believed that the utilization of medical insurance and other policy assistance was very good or good by skeletal fluorosis patients. In Northeast China (30.34%, 27/89), North China (28.41%, 50/176), Southwest China (24.00%, 48/200), and Northwest China (21.43%, 39/182), the proportion of those who believed that the utilization was average and poor were significantly lower than those in East China (11.57%, 96/180) and Central China (10.94%, 35/320, Pcorrect < 0.05). Totally 92.96% (2 747/2 955) of the respondents believed that the cooperation degree of education departments in school monitoring and health education was very good or good, and there were significant differences between different regions (χ 2 = 26.11, P < 0.001), and the highest proportion of respondents who believed that the degree of cooperation was average and poor was in Southwest China (12.63%, 37/293). Conclusions:Except for the East China and Central China, there are different degrees of problems in the organization management and/or departmental coordination and cooperation between departments of endemic fluorosis and arsenicosis prevention and control, especially in the Southwest region. All regions should raise awareness of risk prevention and control, strengthen joint prevention and control, and integrate medical and prevention mechanisms, and consolidate and improve the achievements of endemic fluorosis and arsenicosis prevention and control.

Objective To develop a risk management system for complications associated with peripheral venous indwelling needles and to evaluate its application effect in order to reduce the risk of related complications.Methods We designed a comprehensive risk management system for peripheral intravenous indwelling needle complications,integrating specialized evidence-based guidelines with clinical practice insights,including 5 modules:intelligent assessment and decision support,intelligent inspection reminders,educational modules,collaborative case management procedures,and a knowledge base.Patients admitted to the neurology and internal classification metabolism departments of a tertiary hospital in Jilin Province were conveniently selected as the research subjects.Patients were assigned to a control group(from May to July 2022,before the implementation of the system)and an experimental group(from September to December 2022,after the implementation of the system).The incidence of complications,duration of indwelling needle,compliance rate of core indicators for nursing quality and number of nursing consultations were compared between the groups.Additionally,a self-administered questionnaire was used to assess clinical nurses'evaluations of the system.Results A total of 189 patients were included in the experimental group and 177 patients in the control group.The incidence of complications associated with peripheral intravenous indwelling needles was lower than that in the control group.The duration of indwelling peripheral intravenous needles was longer than that in the control group.The quality compliance rate of peripheral venous indwelling needle care in the experimental group was higher than that in the control group,and the number of consultation cases in the experimental group was higher than that in the control group.Comparisons between the 2 groups showed statistically significant differences for all indicators(P＜0.05).The nurses'recognition rates for the system's user-friendliness,professional guidance,and patient benefit were 77.78％,81.74％,and 82.13％,respectively.Conclusion The application of a peripheral vein indwelling needle complication risk management system can reduce the incidence of complications,prolong the duration of indwelling,and improve nursing quality.Nurses have a high recognition of this system.

Objective To evaluate the efficacy of the DrCloudme platform in follow-ups of intracranial aneurysm(IA)patients.Methods A randomized controlled trial was conducted with 120 IA patients treated at Hechi People's Hospital from July 2021 to June 2024.Participants were equally allocated via random number table method into two groups:The control group(n=60)received conventional telephone follow-up post interventional embolization,while the intervention group(n=60)uti-lized the DrCloudme platform for digital follow-up management.Outcome measures included medical compliance,social functio-ning(assessed by Social Disability Screening Schedule,SDSS),quality of life(evaluated using Quality of Life Instrument for Head and Neck Cancer,QLICP-HN),follow-up completion rates,and patient satisfaction.Results The observation group dem-onstrated significantly higher medical compliance,follow-up completion rate,and follow-up patient satisfaction compared to the control group(P＜0.05).Additionally,the observation group had lower SDSS scores and higher QLICP-HN scores,indicating better social function and quality of life(P＜0.05).Conclusion The DrCloudme platform can not only improve the follow-up completion rate for healthcare providers,but also enhance medical compliance,social functioning,and quality of life among dis-charged IA patients.Moreover,it significantly boosts patient satisfaction with follow-ups.

Objective To understand phenotype conversion in patients with first-episode depression over a 7-year period,to explore the longitudinal disease characteristics and functional outcomes of transitions and non-transitions,and to further analyse the relevant factors affecting transitions.Methods A total of 346 patients with Hamilton depression scale-17(HAMD-17)score≥18,aged 18-60 years and a single episode of major depressive disorder were included in the study.They were follow-up for 7 years to assess their natural history including demographic data,disease characteristics,whether transitions to manic occurred,treatment status.At the end of the 7-year follow-up,treatment emergent symptom scale(TESS),medication adherence rating scale(MARS),and global assessment function(GAF)were used to evaluate adverse reactions,compliance to medication,and patient's overall functional level.Patients were divided into two groups based on the occurrence of mania or hypomania episodes during the 7-year period:the conversion group(those who developed episodes)and the non-conversion group(those who did not).Results A total of 138 patients were followed up for 7 years,including 54 patients(39.1%)in the conversion group and 84 patients(60.9%)in the non-conversion group.When the first episode was enrolled at baseline,the age of first episode was earlier in the conversion group than in the non-conversion group[(27.63±9.63)years vs.(41.20±11.92)years],and there were differences in marital status(unmarried 40.7%vs.7.1%,first marriage 53.7%vs.85.7%,remarriage 3.7%vs.2.4%,separated/divorced 0.0%vs.2.4%,widowed 1.9%vs.2.4%).The proportion of patients with precipitating factors was lower in the conversion group(29.6%vs.48.8%)and shorter duration of untreated psychosis(DUP)[60(15,90)d vs.90(30,180)d].The treatment method in the conversion group had lower only used antidepressant drugs(61.1%vs.81.0%)and more antidepressant combined with mood stabilizers(31.5%vs.16.7%)(all P<0.05).In the 7 years,total number of episodes in the conversion group was more than in the non-conversion group(4.33±1.21 vs.2.70±1.25,P<0.05).By the end of 7 years,the GAF score was lower in conversion group than in the non-conversion group(66.57±8.22 vs.69.21±7.20,P<0.05).Dichotomous unconditional logistic regression analyses revealed that age at first episode(OR=1.109,95%CI:1.058-1.161,P<0.001),DUP(d)(OR=1.005,95%CI:1.001-1.009,P=0.017),was an independent influencing factor on conversion over a 7-year period in patients with first-episode depressive disorders.Conclusion The rate of conversion over 7 years in patients with first-episode depressive disorder is 39.1%in the present cohort and converted patients had relatively earlier age of onset,more pre-onset without inducement,shorter DUP(d),more recurrence,higher the rate of combined treatment and worse overall functional outcome.

Objective To explore the role of the brief visuospatial memory test-revised(BVMT-R)in predicting the clinical conversion to psychosis in subjects with clinical high-risk for psychosis(CHR-P).Methods A total of 217 CHR subjects were recruited and assessed using BVMT-R at baseline.Participants were followed up for three years to determine whether they converted to psychosis.The relationship between BVMT-R total score and CHR-P conversion probability was analyzed using generalized additive model,and the cutoff values of BVMT-R total score for predicting CHR-P conversion were calculated by maximally selected rank statistics.Then,the total BVMT-R score was stratified into different intervals based on the cutoff values obtained as previously described.Finally,the positive likelihood ratios and the conversion rates at different time points were calculated for each interval.Results A total of 168 subjects with CHR-P completed the 3-year follow-up assessment.According to the results of the generalized additive model,the relationship between the BVMT-R total score and CHR-P conversion probability exhibited the characteristics of a piecewise function model.The cutoff values identified using the maximally selected rank statistics method were 18 and 29,which divided the BVMT-R total scores into three intervals:0-18,19-29,and 30-36.The positive likelihood ratios of the three intervals for predicting CHR-P psychosis conversion were significantly different(all P<0.01).All three intervals had significantly different rates of psychosis conversion at different follow-up time points(all P<0.01).Conclusion The total BVMT-R score can be divided into three intervals,each associated with a distinct positive likelihood ratio for predicting psychosis conversion in CHR-P individuals.Accordingly,the BVMT-R total score may serve as a preliminary indicator for estimating the probability of psychosis conversion in the CHR-P population.
