Childhood obesity has become a global public health issue. Current research indicates that early life obesogen exposure has emerged as a significant risk factor for childhood obesity. While obesogens have been confirmed to influence the development and progression of childhood obesity through mechanisms such as endocrine disruption and epigenetic programming, controversies remain regarding the establishment of causal relationships, assessment of combined exposures, and validation of transgenerational effects in humans. In recent years, novel approaches including multi-omics technologies, exposome-based analysis, and multigenerational cohort studies have integrated dynamic biomarker monitoring with analyses of social-environmental interactions, offering new perspectives and methodologies for constructing a systematic "exposure-mechanism-outcome" research framework. This article reviews literature from PubMed and Web of Science up to August 2025 on the association between early life obesogen exposure and childhood obesity, summarizing evidence on the health effects of early life obesogen exposure, major exposure pathways and internal exposure assessment, interactions and amplifying effects of social and environmental factors, as well as the biological mechanisms underlying obesogen action. It further examines current research frontiers and challenges, aiming to provide a theoretical foundation for early prevention and precision intervention of childhood obesity.

ObjectiveTo explore the clinical efficacy and safety of Da Chaihutang （DCH） for the treatment of sepsis with Yang syndrome. MethodsA total of 70 patients suffering from sepsis with Yang syndrome were randomly divided into an observation group and a control group， with 35 cases in each group. They both received standard Western medicine treatment. The observation group was additionally given a dose of DCH， which was boiled into 100 mL and taken twice. The control group was additionally given an equal volume and dosage of warm water. The intervention lasted for three days. The 28-day all-cause mortality and the changes in the following indicators before and after intervention were compared between the two groups， including sequential organ failure assessment （SOFA）， acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ） score，white blood cell （WBC），the percentage of neutrophils （NEU%），C-reactive protein （CRP），procalcitonin （PCT），alanine transaminase （ALT），aspartate transaminase （AST），total bilirubin （TBil），creatinine （Cr），blood urea nitrogen （BUN），acute gastrointestinal injury （AGI） grade，gastrointestinal dysfunction score （GDS），serum intestinal fatty acid-binding protein （iFABP）， citrulline （CR），platelet （PLT），prothrombin time（PT），activated partial thromboplastin time （APTT），fibrinogen （Fib），international normalized ratio （INR），and D-dimer （D-D）. ResultsThere was no significant difference between the two groups regarding 28-day all-cause mortality. After the intervention，SOFA，WBC，PCT，and Cr were significantly decreased， and PLT was significantly increased in the control group （P<0.05）. SOFA，APACHE Ⅱ，NEU%，CRP，PCT，ALT，AST，Cr，BUN，AGI grade，GDS，and serum iFABP and CR were significantly improved in the observation group （P<0.05）. After the intervention，APACHE Ⅱ，PCT，AGI grade，GDS，and serum iFABP in the observation group were significantly lower than those in the control group ，while CR and PLT were higher （P<0.05，P<0.01）. There were significant differences regarding the gap of SOFA，APACHE Ⅱ，AST，TBil，AGI grade，GDS，iFABP，CR， and PLT between the two groups （P<0.05，P<0.01）. There were slight differences regarding PT，APTT，Fib，INR，and D-D between the two groups，which were in the clinical normal range. ConclusionOn the basis of Western medicine， DCH helped to reduce sepsis severity and improved multiple organ dysfunction with high clinical efficacy and safety， but further research on its impact on the prognosis of patients with sepsis is still required.

OBJECTIVE: To analyze the effect of altitude on NIH-CPSI score in patients with chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) Methods: Clinical data and the results of NIH-CPSI Questionnaire of the 321 patients with CP/CPPS at different altitudes were collected from March 2021 to March 2022. And the influence of altitudes on NIH-CPSI score of CP/CPPS was analyzed. RESULT: The NIH-CPSI score of patients living at an altitude of 4 300 m was significantly higher than that of patients living at an altitude of 1 500 m and 2 200 m. The CP/CPPS patients who lived in the higher altitude had more severe symptoms of pain and urination as well as lower scores of life quality (P<0.05). CONCLUSION NIH-CPSI score increased significantly with higher altitude, indicating more severe symptoms and decreased quality of life in CP/CPPS patients. These findings highlight the need for management strategies for specific heights in patients with CP/CPPS.

Objective To prepare tubeimoside Ⅲ nanoemulsion(TBMⅢ-NE)and evaluate its adjuvant effect in vaccines.Methods TBMⅢ-NE was prepared using low-energy emulsification.Dynamic light scattering was used to characterize the particle size and polydispersity index of the obtained TBMⅢ-NE,and transmission electron microscopy(TEM)was employed to observe the morphology.CCK-8 assay was utilized to determine the cytotoxicity of TBMⅢ-NE on bone marrow-derived dendritic cells(BMDCs).The in vitro safety of TBMⅢ-NE was evaluated using a hemolysis assay.The ability of TBMⅢ-NE to promote the phagocytosis of antigens by DC2.4 cells was observed using confocal laser microscopy.After co-incubation of TBMⅢ-NE with BMDCs,the expression levels of CD40,CD86,MHC-Ⅰ,and CCR7 on the surface of BMDCs were detected using flow cytometry,and the levels of cytokines in the supernatant of BMDCs were measured using enzyme-linked immunosorbent assay(ELISA).After female BALB/c mice were immunized with the SARS-CoV-2 antigen RBD in combination with TBMⅢ-NE,ELISA was conducted to determine the serum levels of specific IgG,IgG2a,and IgG1 antibodies.The number of specific IFN-γ-secreting cells in mouse splenocytes was detected using enzyme-linked immunospot(ELISpot)assay.Results The prepared blank nanoemulsion(BNE)and TBMⅢ-NE were in a particle size of 25.46 and 25.89 nm,and a polydispersity index of 0.214 and 0.125,respectively.TEM displayed that TBMⅢ-NE was in uniform sphere and well dispersed.When the TBMⅢ-NE adjuvant was diluted by 400-fold,the survival rate of BMDCs was approximately 86%.Compared with free TBMⅢ,the hemolytic toxicity of TBMⅢ-NE was significantly reduced(P<0.01).TBMⅢ-NE promoted the phagocytosis of antigens by DC2.4 cells and significantly increased the expression of CCR7 on the surface of BMDCs(P<0.05),indicating its potential to promote more dendritic cells to effectively migrate to lymph nodes.TBMⅢ-NE also promoted the expression of IL-6 and IL-1β in the supernatant of BMDCs(P<0.05).When combined with RBD,TBMⅢ-NE significantly increased the levels of specific IgG,IgG2a,and IgG1 antibodies in mouse serum(P<0.01)and promoted the secretion of specific IFN-γ in splenocytes(P<0.01),indicating that TBM Ⅲ-NE could enhance specific cellular immune responses.Conclusion A stable and highly effective TBMⅢ-NE that can induce humoral and cellular immune responses is successfully prepared.

As a new generation of time-of-flight mass spectrometry,multiple-reflection time-of-flight mass spectrometry(MR-TOF-MS)has been increasingly applied in the fields such as nuclear physics,chemistry,and biology due to its ultra-high resolution and rapid analysis capabilities.However,the analytical performance of MR-TOF-MS largely depends on the ion bunch state entering the mass analyzer.In this study,a rectangular ion trap(RIT)was developed,designed and processed using printed circuit board technology,as an ion accumulating and focusing device for MR-TOF mass analyzer.Compared to traditional ion traps composed of two sets of planar electrodes,this RIT had higher voltage utilization efficiency,resulting in more efficient ion collection and focusing.The ions were cooled to a sufficiently small bunch for precise mass measurement with MR-TOF-MS mass spectrometry in only 1 ms of cooling time in the RIT,then orthogonally ejected to the MR-TOF mass spectrometer for mass analysis.Experimental results indicated that the working cycle,ion flux,and ion focusing state of the RIT fully met the requirements of the MR-TOF mass analyzer.When coupled with the MR-TOF mass analyzer,the RIT enabled MR-TOF-MS to achieve a mass resolution of 1.5×105.

Objective To compare the efficacy of stenting in the treatment of idiopathic intracranial hypertension(IIH)complicated by different types of venous sinus stenosis(VSS).Methods The clinical data of 48 patients with IIH complicated by VSS,who received stenting therapy at the First Affiliated Hospital of Zhengzhou University of China from January 2019 to September 2023,were retrospectively analyzed.According to the type of VSS,the patients were divided into intrinsic stenosis group(n=20)and the extrinsic stenosis group(n=28).The improvement of symptoms,Frisén grade of papilledema,lumbar puncture opening pressure(LPOP),trans-stenosis pressure gradient(△P)of VSS,and surgery-related complications were compared between the two groups.Results The mean age of the patients in the intrinsic stenosis group was greater than that of the patients in the extrinsic stenosis group(41.60 years vs.35.25 years,P=0.049).The length of the narrowed segment in the extrinsic stenosis group was 22.5 mm,which was significantly longer than 19.0 mm in the intrinsic stenosis group(P=0.007).The postoperative Frisén grade of papilledema in the extrinsic stenosis group was obviously lower than that in the intrinsic stenosis group(P=0.037).No statistically significant differences in the other clinical data existed between the two groups(all P＞0.05).After stenting,all of the median △P,mean LPOP,and median Frisén grade of papilledema were decreased significantly when compared with their preoperative values(all P＜0.001),and the postoperative 3-day median Frisén grade of papilledema in the extrinsic stenosis group was much lower(P=0.037).The patients were followed up for one year,the clinical symptoms of the patients in both groups were improved to varying degrees.At the time of discharge,the proportion of patients having no symptoms of papilledema in the extrinsic stenosis group was 57.1％,which was higher than 22.2％in the intrinsic stenosis group(P=0.049),and no statistically significant differences in the improvements of other symptoms existed between the two groups(all P＞0.05).There was no significant difference in the incidence of complications between the two groups(P=0.563).Conclusion Venous sinus stenting can effectively treat patients with IIH complicated by different types of VSS.

Objective To compare the clinical efficacy of medication and stenting in treating patients with idiopathic intracranial hypertension complicated by venous sinus stenosis.Methods The clinical data of 74 patients with idiopathic intracranial hypertension complicated by venous sinus stenosis,who were admitted to the First Affiliated Hospital of Zhengzhou University of China from January 2020 to June 2023,were retrospectively analyzed.The patients were divided into medication group(n=35,receiving drug therapy)and stenting group(n=39,receiving stent implantation therapy).Before and after treatment,lumbar puncture and fundus examinations were performed,and the postoperative improvements in intracranial pressure and papillary oedema were evaluated.The changes in the median papillary oedema Frisén grade and the average opening pressure of lumbar puncture were compared between the two groups during hospitalization period.The improvement degrees of the clinical symptoms determined at discharge,as well as at the 6 months and 12 months after discharge were compared between the two groups.The incidence of complications during the follow-up period in the two groups was recorded.Results The time interval from onset to treatment in the stenting group was longer than that in the medication group(2 months vs.one month,P=0.021),and the differences in the other baseline data between the two groups were not statistically significant(all P＞0.05).After treatment,different degrees of improvement were obtained in both groups(all P＞0.05).At the time of discharge,the degree of median papillary oedema in the stenting group was Frisén grade I,which was lower than Frisén grade Ⅱ in the medication group(P=0.011);the average opening pressure of lumbar puncture in the stenting group was 205.26 mm H2O,which was lower than 248.14 mm H2O in the medication group(P=0.002).The proportions of patients having no symptom or showing symptom improvement in the stenting group and in the medication group at the time of discharge were 74.4％and 45.7％respectively(P=0.017),which at the time of 6 months after discharge were 84.6％and 48.6％respectively(P=0.001)and at the time of 12 months after discharge were 87.2％and 57.1％respectively(P=0.004).No statistically significant difference in the incidence of complications existed between the two groups(10.3％and 8.6％respectively,P=1.000).Conclusion For the treatment of patients with idiopathic intracranial hypertension complicated by venous sinus stenosis,stent implantation therapy is superior to medication therapy in quickly and effectively relieving papillary oedema,decreasing lumbar puncture opening pressure,and improving their corresponding symptoms and signs,with satisfactory patient's prognosis and clinical safety.

Immunoassays are widely used in medicine, food, environment and other fields due to having the advantages of simpleness, rapidness and accuracy. Combining immunoassays with nanomaterials can improve the performance of immunoassays. Compared with traditional nanomaterials, upconversion nanoparticles (UCNPs) have excellent optical properties such as good photostability, long luminescence lifetime and narrow and tunable emission bands, which can significantly reduce background noise and improve analytical sensitivity when combined with immunoassay. This paper briefly introduces the luminescence mechanism of UCNPs, summarizes the synthesis and surface modification methods of UCNPs. And then 5 UCNPs-based immunoassay techniques, namely, fluorescence resonance energy transfer, inner filter effect, magnetic separation technique, upconversion-linked immunosorbent assay and upconversion immunochromatography, are discussed in detail. These sensing protocols of UCNPs-based immunoassays have been successfully utilized to detect various targets, including small molecules, macromolecules, and pathogens, all of which closely related to food safety, human health, and environmental pollution. Finally, the challenges and prospects of this technique are summarized and prospected. Although the UCNPs immunoassays based on antibodies and antigens have made great progress, most of the research is still in the stage of laboratory, and there is a long way to go to realize its social applications. There is a series of challenges need to be overcome. (1) Designing excellent water soluble and dispersive upconversion nanomaterials is needed. Hydrophilic ligands are bound to smaller upconversion nanoparticles and removing hydrophobic surface ligands are the most widely used methods to improve solubility and dispersity. (2) Multi-detection technology platforms and multi-mode simultaneous detection platforms have great potential, which will improve the efficiency of point of care detection. (3) The researchers also need to focus on some important problems. For examples, the upconversion luminescence efficiency of UCNPs is difficult to maintain, the synthesis method is complex, and the surface modification degree and functionalization are difficult to control.

The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective:To explore the clinical efficacy of areola approach endoscopic thyroidectomy (AET) and gasless axillary approach endoscopic thyroidectomy (GAET) in the treatment of papillary thyroid carcinoma (PTC) patients.Methods:A total of 96 PTC patients from the Thyroid Surgery Department of Linyi People’s Hospital from May. 2019 to May. 2022 were selected and randomly divided into 48 patients using a random number table method.
