High-performance liquid chromatography(HPLC) was used to determine the content of three major components in Citri Reticulatae Semen(CRS), including limonin, nomilin, and obacunone. The chromaticity of the CRS sample during salt processing and stir-frying was measured using a color difference meter. Next, the relationship between the color and content of the salt-processed CRS sample was investigated through correlation analysis. By integrating the oil bath technique for processing simulation with HPLC, the changes in the relative content of nomilin and its transformation products were analyzed, with its structural transformation pattern during processing identified. Additionally, RAW264.7 cells were induced with lipopolysaccharides(LPSs) to establish an inflammatory model, and the anti-inflammatory activity of nomilin and its transformation product, namely obacunone was evaluated. The results indicated that as processing progressed, E~*ab and L~* values showed a downward trend; a~* values exhibited a slow increase over a certain period, followed by no significant changes, and b~* values remained stable with no significant changes over a certain period and then started to decrease. The limonin content remained barely unchanged; the nomilin content decreased, and the obacunone increased significantly. The changing trends in content and color parameters during salt-processing and stir-frying were basically consistent. The content of nomilin and obacunone was significantly correlated with the colorimetric values(L~*, a~*, b~*, and E~*ab), while limonin content showed no significant correlation with these values. By analyzing HPLC patterns of nomylin at different heating temperatures and time, it was found that under conditions of 200-250 ℃ for heating of 5-60 min, the content of nomilin significantly decreased, while the obacunone content increased pronouncedly. The in vitro anti-inflammatory activity results indicated that compared to the model group, the group with a high concentration of nomilin and the groups with varying concentrations of obacunone showed significantly reduced release of nitric oxide(NO)(P<0.01). When both were at the same concentration, obacunone showed better performance in inhibiting NO release. In this study, the obvious correlation between the color and content of major components during the processing of CRS samples was identified, and the dynamic patterns of quality change in CRS samples during processing were revealed. Additionally, the study revealed and confirmed the transformation of nomilin into obacunone during processing, with the in vitro anti-inflammatory activity of obacunone significantly greater than that of nomilin. These findings provided a scientific basis for CRS processing optimization, tablet quality control, and its clinical application.

A single-center, randomized, double-blind, dose-controlled trial of modified Sini Powder in treating mild to moderate generalized anxiety disorder(GAD) in the patients with syndrome of liver depression transforming into fire was conducted at Xiyuan Hospital, China Academy of Chinese Medical Sciences. A total of 80 patients with mild to moderate GAD and the syndrome of liver depression transforming into fire were included. Patients were assigned by the central randomization system at a ratio of 3∶1 into an observation group(n=60, receiving a conventional-dose of granules of modified Sini Powder) and a control group(n=20, receiving low-dose granules with the active ingredients being 50% of that in observation group). Assessments were conducted before treatment(baseline), after 2 weeks of introduction, after 2/4/8 weeks of treatment, and after 4 weeks of follow-up. The results were summarized as follows. In terms of primary outcome indicators, the observation group(62.2%) showed higher total response rate than the control group(26.6%)(P<0.05), and greater Hamilton anxiety scale(HAMA) score reduction after 8 weeks of treatment(P<0.05). In terms of secondary outcome indicators, the HAMA score(somatic anxiety score), traditional Chinese medicine(TCM) syndrome scores, Pittsburgh sleep quality index(PSQI) scale, and clinical global impression(CGI) scale score in the observation group showed a significant compared to the control group at each visit points(P<0.05). Adverse events occurred in 10 cases, including 9(16.9%) cases in the observation group and 1(6.6%) case in the control group. No adverse reaction was observed. In conclusion, conventional-dose modified Sini Powder demonstrated superior efficacy and favorable safety for mild and moderate GAD in the patients with the syndrome of liver depression transforming into fire over low-dose treatment.

Normal heart function depends on complex regulation by the brain, and abnormalities in the brain‒heart axis affect various diseases, such as myocardial infarction and anxiety disorders. However, systematic tracking of the brain regions associated with the input and output of the heart is lacking. In this study, we injected retrograde transsynaptic pseudorabies virus (PRV) and anterograde transsynaptic herpes simplex virus (HSV) into the left ventricular wall of mice to identify the whole-brain regions associated with the input to and output from the heart. We successfully detected PRV and HSV expression in at least 170 brain subregions in both male and female mice. Sex differences were discovered mainly in the hypothalamus and medulla, with male mice exhibiting greater correlation and hierarchical clustering than female mice, indicating reduced similarity and increased modularity of virus expression patterns in male mice. Further graph theory and multiple linear regression analysis of different injection timelines revealed that hub regions of PRV had highly similar clusters, with different brain levels, suggesting a top-down, hierarchically transmitted neural control pattern of the heart. Hub regions of HSV had scattered clusters, with brain regions gathered in the cortex and brainstem, suggesting a bottom-up, leapfrog, multipoint neural sensing pattern of the heart. Both patterns contain many hub brain regions that have been previously overlooked in brain‒heart axis studies. These results provide brain targets for future research and will lead to deeper insight into the brain mechanisms involved in specific heart conditions.

Tricellulin, a key tricellular tight junction (TJ) protein, is essential for maintaining the barrier integrity of acinar epithelia against macromolecular passage in salivary glands. This study aims to explore the role and regulatory mechanism of tricellulin in the development of salivary gland hypofunction in Sjögren's syndrome (SS). Employing a multifaceted approach involving patient biopsies, non-obese diabetic (NOD) mice as a SS model, salivary gland acinar cell-specific tricellulin conditional knockout (Tric^CKO) mice, and IFN-γ-stimulated salivary gland epithelial cells, we investigated the role of tricellulin in SS-related hyposalivation. Our data revealed diminished levels of tricellulin in salivary glands of SS patients. Similarly, NOD mice displayed a reduction in tricellulin expression from the onset of the disease, concomitant with hyposecretion and an increase in salivary albumin content. Consistent with these findings, Tric^CKO mice exhibited both hyposecretion and leakage of macromolecular tracers when compared to control animals. Mechanistically, the JAK/STAT1/miR-145 axis was identified as mediating the IFN-γ-induced downregulation of tricellulin. Treatment with AT1001, a TJ sealer, ameliorated epithelial barrier dysfunction, restored tricellulin expression, and consequently alleviated hyposalivation in NOD mice. Importantly, treatment with miR-145 antagomir to specifically recover the expression of tricellulin in NOD mice significantly alleviated hyposalivation and macromolecular leakage. Collectively, we identified that tricellulin deficiency in salivary glands contributed to hyposalivation in SS. Our findings highlight tricellulin as a potential therapeutic target for hyposecretion, particularly in the context of reinforcing epithelial barrier function through preventing leakage of macromolecules in salivary glands.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

Objective:To design a single-line low-temperature plasma ablation electrode, aiming to solve the problem of uniform, continuous and stable microbubbles generated by conventional electrodes, and improve the ablation and cutting effect of low-temperature plasma.Methods:The structures of low temperature plasma three-wire electrode and single-line electrode were modeled in SolidWorks 2021 3D modeling software, and the prototype was made by 3D printing. The finite element analysis of electric field and temperature field of the two kinds of electrode ablation process was carried out by COMSOL Multiphysics 6.1 software, and the validity and correctness of the finite element simulation model were verified by temperature test experiment, and the ablation effect and plasma excitation process of the two kinds of electrode were compared by tissue ablation experiment and low temperature plasma excitation experiment.Results:The results of finite element analysis showed that the maximum surface temperature of three-wire electrode and single-wire electrode were 70.2 and 63.3 ℃, respectively, and the surface temperature of single-wire electrode was more ideal, and the maximum electric field intensity of the two electrodes was more than 1.0 × 10 7 V/m, which met the electric field condition of microbubble breakdown. The electric field intensity of the two ends of the three-wire electrode was much higher than that of the other regions, while the electric field intensity of the single-wire electrode had no obvious sudden change and fluctuation. The experimental values of the temperature at the electrode surface and a distance of 1 cm on the electrode surface were basically consistent with the simulation values, the degree of fit was good, and the relative error was 3.2%. The highest ablation temperature of single linear electrode on pig fat was 46.8 ℃. After ablation, there was no coking area in morphology, and the tissue cutting depth of 0.5 mm could be reached in 1 s. When connected to the energy platform, microbubbles would occur on the working electrode surface of the single-wire electrode; when 6 ms was electrified, the working electrode surface was completely covered by microbubbles; when 9 ms was energized, the low-temperature plasma was excited and the blue-purple plasma could be seen; when 25 ms was energized, the microbubbles were still regular and stable. Conclusions:A kind of single-line low-temperature plasma ablation electrode is designed, which can produce uniform, continuous and stable microbubbles and achieve better ablation and cutting effect than the traditional electrode.

Most patients with differentiated thyroid cancer have a good prognosis after radioiodine-131 therapy,but a small number of patients are insensitive to radioiodine-131 therapy and even continue to develop disease.At present,some targeted drugs can improve progression-free survival in patients with radioactive iodine-refractory differentiated thyroid cancer(RAIR-DTC),such as sorafenib and levatinib,have been approved for the treatment of RAIR-DTC.However,due to the presence of primary and acquired drug resistance,drug efficacy in these patients is unsatisfactory.This review introduces the acquired drug resistance mechanism of sorafenib in the regulation of mitogen-activated protein kinase(MAPK)and phosphatidylinositol-3-kinase(PI3K)pathways and proposes related treatment strategies,in order to provide a reference for similar drug resistance mechanism of sorafenib and effective treatment of RAIR-DTC.

Objective:To investigate the cognitive functions of temporal lobe epilepsy (TLE) patients with bilateral asynchronous interictal discharges.Methods:A total of 162 TLE patients who were treated at Zhongshan Hospital, Fudan University, from June 2021 to December 2023 were collected. According to the interictal scalp electroencephalogram, TLE patients were classified to the TLE with bilateral temporal asynchronous interictal epileptiform discharges ( n=51) and TLE with unilateral temporal epileptiform discharges ( n=111). Unilateral TLE patients were divided into TLE with right ( n=48) and left ( n=63) temporal epileptiform discharges. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Digital Span (DS), Verbal Fluency Test (VFT), the third part of Color Word Test (CWT-C), Trail Making Test-B (TMT-B), Symbol Digit Modalities Test (SDMT), Auditory Verbal Learning Test (AVLT), Rey-Osterrieth Complex Figure (ROCF), and Similarity Comprehension Test were performed for the participants. The differences of cognitive functions between patients with bilateral and unilateral temporal discharges were compared. Univariate and multivariate Logistic regression models were used to analyze the risk factors for patients with bilateral temporal asynchronous discharges. Spearman analysis was used to explore the correlation between cognitive function and clinical indicators. Results:In the group of TLE patients with bilateral asynchronous discharges compared to those with unilateral discharges, the completion time of CWT-C [67 (55, 103) s vs 59 (50, 71) s, Z=-2.904, P=0.004], TMT-B [159 (108, 219) s vs 129 (95, 180) s, Z=-2.361, P=0.018] was longer. Additionally, TLE patients with bilateral asynchronous discharges got lower scores of MMSE [28 (26, 29) vs 29 (28, 30), Z=3.098, P=0.002], MoCA [23 (19, 28) vs 27 (23, 28), Z=3.175, P=0.001], AVLT1+2+3 [16.843±6.482 vs 19.162±5.526, t=-2.347, P=0.020], AVLT6 [6 (3, 10) vs 8 (5, 10), Z=3.275, P=0.001], ROCF2 [15 (8, 22) vs 20 (12, 25), Z=2.870, P=0.004], ROCF3 [14 (8, 22) vs 20 (11, 25), Z=2.634, P=0.008], and Similarity Test [13 (8, 18) vs 16 (12, 20), Z=2.387, P=0.017] as well as lower VFT-vegetable and fruit count [15 (13, 19) vs 18 (15, 21), Z=2.402, P=0.016] and SDMT completion count [41 (30, 53) vs 51 (40, 60), Z=3.089, P=0.002]. The multivariate Logistic regression analysis showed that the decrease in AVLT6 scores ( OR=1.546, 95% CI 1.150-2.078, P=0.004) and longer TMT-B time ( OR=1.013, 95% CI 1.001-1.025, P=0.035) were independent risk factors for TLE patients with bilateral asynchronous discharges. Conclusions:Compared to the patients with TLE characterized by unilateral temporal lobe discharges, those with asynchronous discharges in bilateral temporal lobes show statistically significant declines in all domains of cognitive functions, including executive function, memory, and language abilities. Decreased cue recall ability in language memory and prolonged trail-making test in executive function are independent cognitive impairment risk factors for bilateral temporal asynchronous discharges.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
