Depression is a common mental disorder that falls under the category of "stagnation syndrome" in traditional Chinese medicine （TCM）. Its complex pathogenesis poses challenges for the development of novel therapeutic agents. Currently， clinically used antidepressants are often accompanied by significant side effects， and statistics show that about one-third of patients do not respond to these medications. TCM demonstrates advantages in the treatment of depression through multi-target， multi-pathway and multi-mechanistic approaches. Pinelliae Rhizoma， a phlegm-resolving herb， exhibits effects such as drying dampness and resolving phlegm， as well as eliminating stuffiness and reducing masses. The characteristics of harmonizing Yin and Yang and resolving stagnation in the middle energizer align precisely with the pathogenesis of depression syndrome， demonstrating therapeutic efficacy in affected patients. Literature studies have found that the active ingredients of Pinelliae Rhizoma， such as cavidine， baicalein， β-sitosterol， as well as Pinelliae Rhizoma herb pairs， such as Pinelliae Rhizoma-Magnoliae Officinalis Cortex， Pinelliae Rhizoma-husked sorghum， Pinelliae Rhizoma-Prunellae Spica， exhibit significant antidepressant effects. Furthermore， TCM formulas containing Pinelliae Rhizoma as the principal therapeutic agent， such as Banxia Xiexin Tang， Banxia Houpo Tang， and Wendan Tang， as well as formulas incorporating Pinelliae Rhizoma like compound Xiaochaihu Tang， Chaihu Jia Longgu Muli Tang， and Erchen Tang， have also demonstrated favorable antidepressant efficacy. The antidepressant mechanism of these agents may involve modulation of 5-hydroxytryptamine （5-HT） and dopamine （DA） levels， up-regulation of brain-derived neurotrophic factor （BDNF） expression， regulation of the hypothalamus-pituitary-adrenal （HPA） axis， reduction of oxidative stress， modulation of nuclear transcription factor-κB （NF-κB） signaling pathway， and inhibition of microglia-mediated inflammatory responses. This review summarized the antidepressant mechanisms and clinical applications of the active components， herb pairs， and TCM formulas containing Pinelliae Rhizoma， aiming to provide a reference for modern research on the use of Pinelliae Rhizoma in antidepressant therapy.

The repair of bone defects is heavily influenced by the dynamic osteogenic microenvironment. Static scaffolds constructed by traditional 3D printing technology cannot simulate the dynamic nature of the microenvironment during bone defect repair due to the fixed structure, uncontrollable release of active factors, and difficult regeneration of blood vessels, among other factors. Breaking through the limitations of these static scaffolds and realizing the intelligent and dynamic regulation of the osteogenic microenvironment is a key scientific issue in the field of bone tissue engineering. 4D printing technology combines the dynamic responsiveness of bone restoration materials with the concept of intelligent design to regulate the micro and macro structure of scaffolds. This technology provides a new method for bone tissue engineering by responding to endogenous and exogenous stimuli and creating a better osteogenic microenvironment through functionalized design, including drug delivery and antibacterial function. However, this technology currently suffers from challenges related to dynamic response material design, insufficient precision of printing technology, and mismatches between multi-stimulus response systems, metabolic rhythms of bone tissue, and functionalized composite scaffolds. Future research should focus on the development of smart response materials with excellent dynamic responses and bioactivity, the creation of new printing technologies, and the design of personalized and precise bone repair solutions. The aim of this paper is to review the current research status of 4D printing for bone tissue engineering in terms of material types, response mechanisms, and applications to provide a theoretical basis for the development and clinical application of functional bone repair materials in the future.

The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

In clinical practice,common comorbid states between the gastrointestinal and gynecological systems present significant challenges.The strengths of TCM lie in its"treating different diseases with the same therapy"approach using classical prescriptions.In modern medicine,patients with comorbidities are often treated by different departments,and there are differences in the intervention strategies for digestive system and gynecological system diseases.TCM can treat different diseases with the idea of treating different diseases with the same therapy,grasp the core link of the problem,and simplify the treatment.During the clinical apprenticeship,the authors observed that according to the patients'spleen stomach gynecology comorbidity,the treatment can be carried out from Jueyin,which can achieve good efficacy.According to the physiological functions of Jueyin Meridian and Zang-fu organs,starting from the Jueyin failing to close,this article discussed the changes of pathogenesis caused by too much and too little Jueyin failing to close,and used the classic prescriptions to treat the gastrointestinal-gynecological comorbidities.

Japanese encephalitis virus(JEV)usually evades the inhibitory effect of the innate immunity factor type Ⅰ interferon(Ⅰ-IFN)when it infects human cells and tissues.The virus then causes a series of serious symptoms,such as spasticity,neurodegenerative lesions,neuroinflammation,and even death.Generally,JEV escapes innate immunity by inhibiting IFN-α/β production and the interferon Janus kinase-signal transducer and activator of transcription signaling pathway.Because of this special immune escape mechanism,various mouse infection models have been constructed for the study of the pathogenesis of and therapeutic regimens for JEV infections.In this review,based on an exposition of the IFN immune escape mechanism of JEV,we systematically introduce the concept of JEV-infected mouse models and analyze the characteristics of these models and the degree to which they simulate human symptoms.The intention is to develop various new JEV-infected mouse models based on potential new research targets and provide novel ideas for animal models for JEV research.

Objective:To investigate the predictive value of the Japanese nutritional risk index(NRI)for one-year all-cause mortality risk among elderly maintenance hemodialysis (MHD)patients.Additionally, it seeks to compare the predictive abilities of NRI with those of the geriatric nutritional risk index (GNRI)and the mini nutritional assessment short-form(MNA-SF).Methods:This research was conducted as a prospective cohort study.Elderly patients(aged ≥60 years)who underwent hemodialysis treatment at Beijing Friendship Hospital of Capital Medical University for more than three months between July and October 2019 were selected for inclusion.The NRI score was utilized to evaluate the nutritional status of the participants, with the maximum point of the Jordan index designated as the cut-off value, thereby categorizing patients into high-risk and low-risk groups.The follow-up period concluded in August 2020, with all-cause mortality serving as the primary outcome measure.Kaplan-Meier methods were employed to construct survival curves, and the Cox proportional hazards model was applied to analyze the association between NRI and all-cause mortality.Furthermore, area under the curve(AUC) of receiver operating characteristic(ROC)curves were utilized to compare the predictive values of the three nutritional assessment methods(NRI, GNRI, and MNA-SF)regarding mortality risk.Results:A total of 150 patients were included in the study, with a median age of 69(64.75) years.The cohort comprised 73 males(48.7%)and 77 females(51.3%). Based on the NRI, patients were categorized into a low-risk group(NRI<5; n=81, 54.0%)and a high-risk group(NRI ≥ 5; n=69, 46.0%). Of the 150 patients, 147 completed the follow-up.During the follow-up period, 15 patients died, with 13 from the high-risk group and 2 from the low-risk group.The Kaplan-Meier survival curve indicated that the 1-year cumulative survival rate for patients in the high-risk group was significantly lower than the low-risk group (log-rank χ2=11.71, P<0.001). Furthermore, multivariate Cox regression analysis revealed a significant association between NRI and 1-year all-cause mortality in elderly patients undergoing MHD ( HR=3.779, 95% CI: 1.036-13.783, P=0.044). Additionally, NRI demonstrated a high predictive value for 1-year all-cause mortality risk in elderly MHD patients, with an AUC of 0.755(95% CI: 0.654-0.855), a sensitivity of 86.7%, and a specificity of 59.1%.Its predictive capability was slightly superior to that of the GNRI(AUC=0.691, 95% CI: 0.548-0.835)and the MNA-SF(AUC=0.634, 95% CI: 0.475-0.793), although no statistically significant differences were observed( Z=0.880, 1.177, P=0.379, 0.239). Conclusions:The NRI score demonstrates effective predictive capability for one-year all-cause mortality risk in elderly MHD patients and may serve as a more suitable nutritional assessment method for this population.

Objective:To investigate the diagnostic potential of serum Dickkopf-related protein 3(Dkk3)as a novel biomarker for sarcopenia in an elderly Chinese population by examining its correlation with muscle mass, muscle strength, and physical function.Methods:The study included elderly individuals aged ≥60 years from the Health Examination Center of Jiangsu Provincial Hospital between 2021 and 2022, who had independent mobility and were free from acute diseases.Fat and muscle mass were measured using Dual-energy X-ray Absorptiometry(DXA). Grip strength and chair stand test times were employed to assess upper and lower limb muscle strength, respectively.Physical function was evaluated using the Short Physical Performance Battery(SPPB). Serum Dkk3 concentration was measured using a human Dkk3 enzyme-linked immunosorbent assay(ELISA)kit.Results:A total of 108 elderly participants(83 males)were included in the study, with an age range of 60 to 97 years(mean age: 70.6±10.8). Serum Dkk3 concentration was found to be negatively correlated with the skeletal muscle mass index(SMI)( R=-0.292, P=0.002), lower limb muscle mass( R=-0.320, P<0.001), upper limb muscle mass( R=-0.222, P=0.020), and hip muscle mass( R=-0.261, P=0.006). Functional assessments revealed negative correlations with grip strength( R=-0.204, P=0.035), 4-meter walking speed( R=-0.195, P=0.043), the three-position balance test( R=-0.245, P=0.011), and the SPPB score( R=-0.196, P=0.043). Regression analysis indicated that, after adjusting for age, sex, body mass index(BMI), and comorbidities, Dkk3 remained negatively associated with lower limb muscle mass( β=-0.197, P=0.012), hip muscle mass( β=-0.156, P=0.029), and the SPPB score( β=-0.001, P=0.013). The sarcopenia group exhibited a 55.6% higher serum Dkk3 level compared to the control group(76.68±37.62 ng/ml vs.49.27±25.88 ng/ml, P<0.001). Receiver Operating Characteristic(ROC)curve analysis determined the optimal diagnostic threshold to be 80.08 ng/ml, with an area under the curve of 0.726, a sensitivity of 41.98%, and a specificity of 96.30% for detecting sarcopenia. Conclusions:Serum Dkk3 is closely associated with reduced muscle mass in the lower limbs and hips, as well as a decline in physical function, in elderly individuals with sarcopenia.Given its cost-effectiveness and clinical utility, serum Dkk3 shows potential as a meaningful biomarker for diagnosing sarcopenia in the elderly.

Purpose To investigate the role of 18F-FDG PET/CT in predicting histological grade of invasive pulmonary adenocarcinoma in the WHO(2021)classification.Materials and Methods The Clinical,pathological and PET/CT data of 255 patients with invasive pulmonary adenocarcinoma confirmed by surgical pathology were retrospectively analyzed from May 2015 to August 2023.Tertiary tumor grading was performed according to the WHO(2021)classification.The clinicopathologic features,maximum standardized uptake value(SUVmax),maximum standardized uptake,total lesion glycolysis and CT imaging findings were compared among the three tumor grades.Logistic regression analysis was used to screen the independent predictors for grade 3 tumors,and performance evaluation was performed using receiver operating characteristic curve.Results Higher tumor grade was associated with male sex(χ2=11.803,P=0.003),smoking history(χ2=7.702,P=0.021),maximum tumor diameter(H=20.548,P=0.002),lymph node metastasis(P<0.001),vascular cancer thrombus(χ2=33.270,P<0.001),pleural invasion(χ2=15.116,P=0.001)and airway spread(χ2=17.867,P<0.001).SUVmax(H=71.488,P<0.001),total lesion glycolysis(H=30.658,P<0.001)and the proportion of pure solid tumors on CT image(χ2=28.872,P<0.001)all increased significantly with higher tumor grade.A higher SUVmax(OR=1.234,95%CI 1.141-1.334,P<0.001)and pure solid appearance(OR=2.205,95%CI 1.166-4.171,P=0.015)were independent predictors of grade 3 tumors.The area under the receiver operating characteristic curve for SUVmax,CT solid appearance and the combination for predicting grade 3 tumors was 0.793,0.641 and 0.804,respectively,with the SUVmax cut-off of 6.08.Conclusion SUVmax and CT solid appearance are independent predictive factors for grade 3 invasive pulmonary adenocarcinoma.Preoperative 18F-FDG PET/CT can assist in evaluating the grading of invasive pulmonary adenocarcinoma,which improves treatment decision-making.
