Triclosan (TCS) and triclocarban (TCC) are widely used synthetic broad-spectrum antibacterial agents that can enter the human body through the skin, gastrointestinal tract, and other pathways. More and more studies have found that exposure to TCS and TCC can affect human health, but currently, review reports on the health effects of human exposure to TCS and TCC are limited. Therefore, this study reviewed population studies on the relationship between TCS and TCC exposure and health effects by searching the PubMed database, summarized the associated health outcomes, and elucidated the biological mechanisms. A total of 56 studies were retrieved, among which cross-sectional studies (25 studies, 44.64%) and cohort studies (25 studies, 44.64%) accounted for a relatively large proportion, while case-control studies (6 studies, 10.72%) were relatively few. Studies on TCS exposure (48 studies, 85.71%) were far more prevalent than those on TCC exposure (2 studies, 3.57%). The remaining 6 studies involved both TCS and TCC exposure. The research results revealed that TCS exposure was associated with male and female abnormal reproductive functions, fetal growth restriction, abnormal behavior development in children, obesity, gestational diabetes mellitus (GDM), and immune-related diseases. Although the results of different studies show significant differences, they have indicated that exposure to TCS is a potential risk factor for these health problems. Due to the limited number of studies, the evidence for the relationship between TCC exposure and most of the aforementioned health effects is insufficient. Population studies and in vitro and in vivo studies have shown that exposure to TCS and TCC can interfere with the microbial homeostasis, the endocrine system, oxidative stress and immune function of the body, which are potential mechanisms causing adverse health effects. In the future, large-scale prospective cohort studies, as well as in vivo and in vitro studies, are still needed to further clarify the associations between TCS and TCC exposure and health effects, and to deeply explore its mechanism of action. These efforts will provide references for clarifying the human health hazards of TCS and TCC exposure and formulating targeted prevention and control strategies.

Based on the theory of the liver's"using bitter herbs to nourish or purge"from Huangdi Neijing,this paper systematically elucidates the theoretical foundation for treating functional constipation from liver.Focusing on the physiological characteristic of"liver desires to disperse"and the pathological manifestation of"liver bitterness and urgency,"combined with the"liver communicates with the large intestine"theory,this paper establishes a diagnostic and therapeutic framework for managing functional constipation by regulating liver function.The pathological evolution of functional constipation manifests in three distinct stages:in the early stage,liver qi stagnation leads to large intestine qi obstruction,where damaged by an excess of seven emotions resulting in symptoms such as difficult defecation,abdominal bloating,and hypochondriac pain;in the middle stage,liver depression transforms into fire,scorching bodily fluids to generate dryness,thereby creating a pathological interplay of stagnation,fire,and dryness,which is marked by anal heat,dry mouth,and yellow urine;in the late stage,yin deficiency in liver and kidney causes large intestine malnutrition,resulting in a complex pathological state where yin deficiency,collateral blockage,dryness accumulation,and blood stasis intertwine,clinically manifesting as pellet-like stools(resembling sheep feces)and soreness and weakness of the waist and knees.In treatment,the formula design follows the principle of"sweetness to relieve,acridity to tonify,and sourness to purge,"with treatment principles varying across stages.In the early stage,the focus is on dispersing liver and regulating qi,and unblocking the zang-fu viscera;in the middle stage,the priority shifts to clearing heat-fire,nourishing large intestine,and promoting fluid production;whereas,in the late stage,the emphasis lies on nourishing yin,unblocking collaterals,and promoting blood circulation.This staged treatment of functional constipation overcomes the limitations of solely focusing on nourishing large intestine and facilitating feces excretion,thereby advancing the treatment of different stages based on syndrome differentiation and personalized treatment.It provides theoretical support for improving patients' intestinal function and enhancing overall health outcomes.

ObjectiveTo improve the accuracy of discrete element method in simulating the processing of traditional Chinese medicine（TCM） powder system under low shear conditions. MethodsIn this study， extract powders of Tongsaimai tablets and Qige granules were used as the research objects， the angle of repose（AOR） and effective angle of internal friction of the two materials were determined by AOR test method and shear cell test method. Based on the Hertz-Mindlin with JKR V2 contact model and particle scaling theory， taking the particle-particle restitution coefficient（A）， particle-particle static friction coefficient（B）， particle-particle rolling friction coefficient（C）， particle-steel restitution coefficient（D）， particle-steel static friction coefficient（E）， particle-steel rolling friction coefficient（F） and Johnson-Kendall-Roberts（JKR） surface energy（G） as test factors， the simulated contact parameters of Tongsaimai tablets extract powder were first calibrated with a single reference value using AOR as the reference value， and then the simulated contact parameters of Tongsaimai tablets extract powder as well as Qige granules extract powder were co-calibrated with AOR and effective angle of internal friction as the joint reference value， respectively. Then， Plackett-Burman design was used to screen the critical contact parameters that have a significant effect on the simulated reference value， and the steepest ascent design was used to determine the optimal range of the critical contact parameters， finally， the regression model between the critical contact parameters and the simulated reference values was established through the design of the response surface test， and the critical contact parameters were calibrated based on the regression model and the desirability function approach. ResultsThe optimal combination of discrete elemental contact parameters A-G for Tongsaimai tablets extract powder under a single reference value was 0.100， 0.718， 0.616， 0.100， 0.400， 0.250 and 0.075 J·m^-2， which was validated to have relative errors of 0.10% and -8.64% for the simulated AOR and the simulated effective angle of internal friction， respectively. And the optimal combination of discrete elemental contact parameters A-G for Tongsaimai tablets extract powder at the joint reference values was 0.100， 0.682， 0.598， 0.100， 0.521， 0.294 and 0.075 J·m^-2， which was verified to have relative errors of 0.10% and -0.18% for the simulated AOR and the simulated effective angle of internal friction， respectively. The optimal combination of discrete elemental contact parameters A-G for Qige granules extract powder at the joint reference values was 0.150， 0.370， 0.330， 0.150， 0.500， 0.500 and 0.100 J·m^-2， which was verified to have relative errors of 2.70% and -1.30% for the simulated AOR and the simulated effective angle of internal friction， respectively. Compared with the single reference value method， the joint calibration method not only increased the number of the critical contact parameters for characterizing particle-device interactions， but also was more accurate and reliable. ConclusionCompared with the results of single reference value calibration， the results obtained by the method of joint calibration of discrete element simulation contact parameters with AOR and effective angle of internal friction as the reference values are more accurate， which can provide more accurate and reliable simulation physical property data for the simulation experiments of TCM extract powder under low shear process conditions.

Objective:To investigate the additional value of 99Tc m-hydrazinonicotinamide (HYNIC)-Tyr3-octreotide (TOC) SPECT/CT imaging in the diagnosis and treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Methods:A total of 54 patients (28 males and 26 females, age: (52.6±11.7) years) who underwent enhanced CT (MR) and 99Tc m-HYNIC-TOC SPECT/CT in People′s Hospital of Zhengzhou University between December 2017 and June 2023 were analyzed retrospectively. Surgical pathology or biopsy was the gold standard of patients′ diagnosis (primary tumors), and comprehensive evaluation based on pathology, imaging and follow-up results was used as the diagnostic criteria of lesions. McNemar χ2 test was used to compare the diagnostic efficacy of different imaging methods. Results:Pathological results showed that 43 of the 54 patients were with GEP-NETs and 11 were with non-neuroendocrine tumors (NETs). The sensitivities of enhanced CT and enhanced MR in the diagnosis of patients with GEP-NETs were 65.1%(28/43) and 60.0%(15/25) respectively, which increased to 93.0%(40/43) and 92.0%(23/25) with the addition of 99Tc m-HYNIC-TOC imaging ( χ2 values: 8.64, 4.90, P values: 0.002, 0.021). There were 22 and 15 patients showing atypical enhancement on enhanced CT and enhanced MR respectively. The sensitivities of these two methods for GEP-NETs in patients with atypical enhancement were 54.5%(12/22) and 8/15 respectively, which increased to 95.5%(21/22) and 14/15 with the addition of 99Tc m-HYNIC-TOC imaging ( χ2 values: 5.82, 4.17, P values: 0.012, 0.031). Compared with enhanced CT, the detection rates of liver and bone metastatic lesions were improved significantly from 90.8%(158/174) and 55.2%(32/58) to 96.6%(168/174) and 87.9%(51/58) with the addition of 99Tc m-HYNIC-TOC imaging ( χ2 values: 5.79, 9.82, P values: 0.013, 0.001). Compared with enhanced MR, the detection rate of bone metastases was improved significantly from 56.0%(14/25) to 88.0%(22/25) with the addition of 99Tc m-HYNIC-TOC imaging ( χ2=4.08, P=0.039). After 99Tc m-HYNIC-TOC imaging, stages were changed in 7.0%(3/43) of patients and a greater number or extent of metastases were detected in 11.6%(5/43) of patients. 99Tc m-HYNIC-TOC imaging detected additional recurrent or metastatic lesions in 40.0%(8/20) of patients during follow-up compared to enhanced CT. Conclusion:99Tc m-HYNIC-TOC imaging can provide an added value for diagnosing GEP-NETs with atypically enhanced CT(MR), and in the detection of liver metastasis and early bone metastasis, thus helping the optimization of clinical treatment strategies.

Objective Currently, there is no commercially available quantitative detection kit for the main Felis domestic allergen (Fel d 1) in China. To establish a rapid detection method for Fel d 1, this study aims to prepare monoclonal antibodies against Fel d 1 protein. Methods The codon preference of Escherichia coli was utilized to optimize and synthesize the Fel d 1 gene. The prokaryotic expression plasmid pET-28a-Fel d 1 was constructed and used to express and purify the recombinant Fel d 1 protein. Subsequently, the recombinant protein was immunized into BALB/c mice and monoclonal antibodies (mAbs) were prepared by the hybridoma technique. An indirect ELISA was established using the recombinant Fel d 1 as the coating antigen, and hybridoma cell lines were screened for positive clones. The specificity and antigenic epitopes of the mAbs were confirmed by Western blot analysis. Finally, the selected hybridoma cells were injected into the peritoneal cavities of BALB/c mice for large-scale monoclonal antibody production. Results The recombinant plasmid pET-28a-Fel d 1 was successfully constructed, and soluble Fel d 1 protein was obtained after optimizing the expression conditions. Western blot and antibody titer assays confirmed the successful isolation of two hybridoma cell lines, 7D11 and 5H4, which stably secreted mAbs specific to Fel d 1. Antibody characterization revealed that the 5H4 mAb was of the IgG2a subtype and could recognize the amino acid region 105-163 of Fel d 1, while the 7D11 mAb was the IgG1 subtype and could recognize the amino acid region 1-59. Conclusion The high-purity recombinant Fel d 1 protein produced in this study provides a promising alternative for clinical immunotherapy of cat allergies. Furthermore, the monoclonal antibody prepared in this experiment lays a material foundation for the in-depth study of the biological function of Fel d 1 and the development of ELISA detection.
