The role of fluid as a fundamental substance in the organism, encompassing its physiology, characteristics, and function, is widely recognized in medical practice. However, the specific distribution path of fluid remains unclear. Most scholars traditionally characterize the circulation of fluid in the category of qi and blood collaterals, a generalized viewpoint that may limit the refinement of treatment strategies based on syndrome differentiation. Therefore, this paper proposes the concept of fluid collaterals as an independent framework for exploration and discussion. This study investigates the origin and flow of similar concepts of fluid collaterals in ancient Chinese medicine texts. Integrating insights from Western medicine, we analyzed the origin and development of fluid collaterals to clarify that the fluid collaterals are the core of the fluid. Fluid collaterals are proposed as the core regulatory mechanism of fluid, where the collaterals serve as a structural framework. Their physiological functions include storing and transforming fluids, linking yingfen (nutritive level) and weifen (defensive level), and mediating the interplay between fluids and blood. Fluid collaterals are conceptualized as a network system that integrates function, structure, and information transmission, enabling seamless connection and coordination between blood and qi collaterals. From this perspective, two pathological conditions are proposed: fluid collateral stagnation and malnutrition. Drawing on the clinical experiences of our team, we presented novel therapeutic approaches for fluid-related diseases, emphasizing treatments tailored to these specific pathological conditions.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Pristimerin, which is one of the compounds present in Celastraceae and Hippocrateaceae, has antitumor effects. However, its mechanism of action in esophageal squamous cell carcinoma (ESCC) remains unclear. This study aims to investigate the efficacy and mechanism of pristimerin on ESCC in vitro and in vivo. The inhibitory effect of pristimerin on cell growth was assessed using trypan blue exclusion and colony formation assays. Cell apoptosis was evaluated by flow cytometry. Gene and protein expressions were analyzed through quantitative reverse transcription-polymerase chain reaction (qRT-PCR), Western blotting, and immunohistochemistry. RNA sequencing (RNA-Seq) was employed to identify significantly differentially expressed genes (DEGs). Cell transfection and RNA interference assays were utilized to examine the role of key proteins in pristimerin?s effect. Xenograft models were established to evaluate the antitumor efficiency of pristimerin in vivo. Pristimerin inhibited cell growth and induced apoptosis in ESCC cells. Upregulation of Noxa was crucial for pristimerin-induced apoptosis. Pristimerin activated the Forkhead box O3a (FoxO3a) signaling pathway and triggered FoxO3a recruitment to the Noxa promoter, leading to Noxa transcription. Blocking FoxO3a reversed pristimerin-induced Noxa upregulation and cell apoptosis. Pristimerin treatment suppressed xenograft tumors in nude mice, but these effects were largely negated in Noxa-KO tumors. Furthermore, the chemosensitization effects of pristimerin in vitro and in vivo were mediated by Noxa. This study demonstrates that pristimerin exerts an antitumor effect on ESCC by inducing AKT/FoxO3a-mediated Noxa upregulation. These findings suggest that pristimerin may serve as a potent anticancer agent for ESCC treatment.

Objective To evaluate the effects of different non-pharmacological interventions on postpartum depression,and to provide the evidence for the formulation of relevant intervention programs.Methods Databases,including China National Knowledge Infrastructure(CNKI),China Biomedical Literature Database,Wanfang Database,VIP database,PubMed,EMBase,the Cochrane Library,were systematically searched for randomized controlled trials(RCT)on the effects of non-pharmacological interventions on postpartum depression.The search time limit was from the establishment of the database to July 2022.Network meta-analysis was performed using Stata17.0 and Review Manager 5.3 software.Results A total of 43 studies were included,including 14 non-pharmaceutical interventions,involving 4451 parturients.The results of network meta-analysis showed that compared with the usual care group,exercise therapy[SMD=-5.41,95％CI(-6.94,-3.89),P＜0.001],cognitive behavioral therapy[SMD=-4.72,95％CI(-6.13,-3.31),P＜0.001],acupuncture and moxibustion[SMD=-4.52,95％CI(-8.01,-1.03),P＜0.001]and the comprehensive psychotherapy[SMD=-4.64,95％CI(-8.53,-0.75),P＜0.001]had better improvement effects on postpartum depression.The results of the area under the cumulative rank probability map showed that exercise was the best non-pharmacological intervention to improve postpartum depression.Conclusion Exercise has the best effect on improving postpartum depression,and it is recommended that clinical nursing care should be prioritized.However,a large number of high-quality RCTs are still needed for verification.

Retrograde adeno-associated viruses (AAVs) are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks. However, few retrograde AAV capsids have been shown to offer access to cortical projection neurons across different species and enable the manipulation of neural function in non-human primates (NHPs). Here, we report the development of a novel retrograde AAV capsid, AAV-DJ8R, which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques. In addition, intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations. Moreover, AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen. These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations.

Objective: To analyze the epidemiological and molecular characteristics of norovirus outbreaks in schools in Xicheng District of Beijing from 2017 to 2022, so as to provide evidence for the prevention and control of norovirus outbreaks in schools. Methods: Data of norovirus outbreaks in schools in Xicheng District, Beijing during 2017 to 2022 were collected and analyzed by descriptive epidemiological methods. Realtime PCR was used to detect the nucleic acid of group GⅠand GⅡnorovirus, the positive norovirus nucleic acid samples were sent to Beijing Center for Disease Control and Prevention for molecular typing. Results: From 2017 to 2022, 185 norovirus outbreaks were reported in schools in Xicheng District, including 166 cluster outbreaks and 19 outbreaks. A total of 2 044 cases were reported, with a total attack rate of 13.92%. There were two peaks in the outbreak time, which were from March to June after the spring semester and from October to December after autumn semester. Primary schools were the most common place of occurrence (101 cases), followed by nursery institutions (68 cases) and secondary schools (16 cases). There were statistically significant differences in the incidence rates among different sites(12.37%, 22.78%, 8.47%, χ2=263.34, P<0.01). There were significant differences in the incidence of vomiting, diarrhea, nausea and stomachache among different students (χ2=263.33, 90.58, 20.42, 30.29, P<0.01). Vomiting was the main symptom in primary school and nursery school children (96.41%, 98.28%), and the diarrhea rate was higher in middle school students (68.22%). The outbreaks were mainly caused by type GⅡ norovirus. The genotype from 2017 to 2021 showed the characteristics of diversity, mainly GⅡ.2[P16], but there was no significant advantage for the GⅡ.2 [P16] during 2019 to 2021. Conclusions The norovirus outbreak in schools in Xicheng district of Beijing from 2017 to 2022 are mainly caused by GⅡ type genome. The main genotype is GⅡ.2[P16]. Norovirus infection mainly occurred in primary schools and kindergartens. For the vulnerable populations, it is necessary to improve the capacity to early identification, student infectious disease management, active infection control and prevention measures, and pathogen surveillance and sporadic case monitoring.

BACKGROUND: Extensive-stage small cell lung cancer (ES-SCLC) is a malignant tumor with remarkable proliferative and invasive ability, which has very poor clinical prognosis due to lack of effective treatments. This study aims to evaluate the efficacy and synergistic effects of radiotherapy (RT) combined with immunotherapy (IT) and chemotherapy (CT) in patients with ES-SCLC. METHODS: A retrospective analysis was performed on 145 ES-SCLC patients treated with first-line CT. Kaplan-Meier analysis and Log-rank tests were used to evaluate survival outcomes, while propensity score matching (PSM) was applied to reduce confounding factors. RESULTS: The median overall survival (mOS) and median progression-free survival (mPFS) for the entire cohort were 15.7 and 6.9 mon, respectively. The IT+CT group had a significantly longer mOS compared to the CT group (17.2 vs 13.5 mon, P=0.047). Similarly, the RT+CT group demonstrated superior mOS (18.5 vs 12.3 mon, P<0.001) and mPFS (7.1 vs 6.2 mon, P=0.006) compared to the CT group. Multivariate analysis identified RT, IT, and Eastern Cooperative Oncology Group performance status (ECOG PS) as independent prognostic factors for mOS (P<0.05), while gender and ECOG PS were independent predictors for mPFS (P<0.05). Following PSM, the RT+CT group continued to exhibit significant advantages in mOS (18.0 vs 12.1 mon, P<0.001) and mPFS (7.1 vs 5.5 mon, P=0.037) compared to the CT group. Notably, the RT+IT+CT group achieved a markedly longer mOS than the IT+CT group (28.5 vs 15.8 mon, P=0.017). Grade 3-4 adverse events occurred in 27.6% of patients, with no grade 5 adverse events reported. CONCLUSIONS The combination of RT, IT, and CT significantly enhances the prognosis of ES-SCLC patients. RT plays a key role in their synergistic effects and demonstrates good safety, warranting further research and clinical application.
