OBJECTIVE To compare the long-term cost-effectiveness of gonadotrophin-releasing hormone analogue （GnRHa） combined with recombinant human growth hormone （rhGH） （combination therapy regimen） versus GnRHa monotherapy （monotherapy regimen） in the treatment of central precocious puberty （CPP）. METHODS From the societal perspective and based on a real-world study conducted at West China Second Hospital of Sichuan University， the cost-effectiveness analysis was performed to compare the long-term cost-effectiveness of two pharmacotherapy regimens for CPP girls， with final height as outcome indexes， using per capita disposable income of rural residents and urban residents （20 133-49 283 yuan） in 2022 as the social willing-to-pay （WTP） threshold. The robustness of the basic analysis result was verified by using one-way sensitivity analysis and probability sensitivity analysis， and the cost-effectiveness of different combinations of long-acting preparations was compared using scenario analysis. RESULTS The basic analysis result showed that the combination therapy regimen required an additional cost of 25 193.49 yuan for every one-centimeter improvement in the final height of girls with CPP compared with the monotherapy regimen， which was not cost-effective for residents in rural areas， but it was cost-effective for residents in urban areas. One-way sensitivity analysis showed that the uncertain factors with potential impacts on the results were， in order， the price of rhGH， the final height of pediatric patients in the combination therapy regimen group， the course of rhGH in the combination therapy regimen group， and the final height of pediatric patients in the monotherapy regimen group. Probabilistic sensitivity analysis indicated that the probability of the combination therapy regimen being cost-effective was higher than that of the monotherapy regimen when WTP was more than 26 010 yuan/cm. When GnRHa long-acting preparation was used for intramuscular injection every 3 months， the combination therapy regimen was not cost-effective for rural residents， but was cost-effective for urban residents； when rhGH long-acting preparation was injected subcutaneously once a week， the combination therapy regimen was not cost-effective for residents in both rural areas and urban areas. CONCLUSIONS The combination of GnRHa and rhGH is only recommended for CPP children with better affordability to improve final height. The benefits， risks， and affordability of treatment should be comprehensively considered before the decisions on pharmacotherapy， to avoid abuse of rhGH due to the blind pursuit of height growth.

[Objective] To establish a new scoring system to predict the perioperative outcomes (operation time, intraoperative blood loss, and trifecta achievement) in patients undergoing robot-assisted partial nephrectomy (RAPN) by integrating the RENAL and Mayo adhesive probability (MAP) scores. [Methods] Clinical data of 178 patients with renal cell carcinoma who underwent RAPN performed by the same surgeon in our hospital during Jan.2015 and Jan.2022 were retrospectively analyzed.The RENAL and MAP scores of all patients were calculated.Linear regression and logistic regression were used to evaluate the associations between the components of the RENAL and MAP scores (a total of 6 variables) and perioperative outcomes.The factors with significant associations were then included into logistic regression analysis to identify independent predictors for constructing an assessment system for perioperative outcomes, and the receiver operating characteristic (ROC) curve was plotted to calculate the area under the curve (AUC) to predict its efficacy. [Results] Multivariate linear regression analysis showed that tumor size (β=6.14, 95%CI: 1.93—10.34, P=0.004), exophytic rate (β=10.60, 95%CI: 3.44—17.76, P=0.004), and perinephric fat thickness (β=16.48, 95%CI: 8.52—24.45, P<0.001) were significantly associated with operation time.Tumor size (β=10.55 95%CI: 5.60—15.49, P<0.001) was associated with both intraoperative blood loss and trifecta achievement (OR=1.73, 95%CI: 1.26—2.36, P=0.001). Multivariate logistic regression analysis of these 3 factors identified tumor size (OR=9.07, 95% CI: 1.18—69.45, P=0.03) and perinephric fat thickness (OR=2.28, 95%CI: 1.86—6.04, P=0.01) as independent predictors of perioperative outcomes.Based on these findings, the tumor size and perinephric fat thickness (RP) scoring was constructed, which demonstrated better predictive ability than RENAL score or MAP score alone (RP vs.RENAL vs.MAP: 0.766 vs.0.548 vs.0.684). [Conclusion] The RP score includes fewer variables than the RENAL and MAP scores but outperforms them.

With the widespread use of antibiotics, drug-resistant bacterial infections have become a significant threat to human health. Finding new antibacterial strategies that can effectively control drug-resistant bacterial infections has become an urgent task. Unlike small molecule drugs that target bacterial proteins, antisense oligonucleotide (ASO) can target genes related to bacterial resistance, pathogenesis, growth, reproduction and biofilm formation. By regulating the expression of these genes, ASO can inhibit or kill bacteria, providing a novel approach for the development of antibacterial drugs. To overcome the challenge of delivering antisense oligonucleotide into bacterial cells, various drug delivery systems have been applied in this field, including cell-penetrating peptides, lipid nanoparticles and inorganic nanoparticles, which have injected new momentum into the development of antisense oligonucleotide in the antibacterial realm. This review summarizes the current development of small nucleic acid drugs, the antibacterial mechanisms, targets, sequences and delivery vectors of antisense oligonucleotide, providing a reference for the research and development of antisense oligonucleotide in the treatment of bacterial infections.

Background The neck, shoulders, and lower back are the primary affected areas of work-related musculoskeletal disorders. In manual tasks, combinations of hand functional height (defined as working height below the waist), awkward postures, and cognitive load are common risk factors. However, there is limited literature documenting how these factors specifically alter biomechanical load on the neck, shoulders, and lower back when working at hand functional height. Objective To explore quantitative differences in biomechanical load on the neck, shoulders, and lower back of workers performing manual tasks at hand functional height under different postures and cognitive load combinations. Methods A 3x2 within-subject design was implemented, with three postures (squat, kneeling, and stoop) and two levels of cognitive load (with cognitive load induced by a 2back task and without cognitive load). Ten male university students were recruited to perform a predetermined assembly task (a sequence of loosening and tightening screws) at hand functional height. Surface electromyography (sEMG) and 3D motion capture system were employed to assess the participants’ trunk biomechanical load in executing the tasks. Additionally, subjective perception, including fatigue, muscle pain, and cognitive load, were evaluated using scales. Results Significant variations in biomechanical load were observed across the three postures (P<0.05). The stoop posture exhibited the lowest muscle activation in most target muscles, except for the sternocleidomastoid, and showed the fastest decline in instantaneous median frequency (IMF) of the erector spinae, with a rate of (-0.050±0.008) Hz per unit time (0.128 s), and the greatest trunk flexion angle (35.14°±4.40°). Performing the task by squatting resulted in the highest muscle activation, especially in the upper trapezius, where maximum voluntary contraction percentage reached 20.07%±1.26%. In addition, the squatting posture also resulted in larger joint angles in the sagittal plane for the neck (−7.03°±2.70°), shoulders (60.20°±7.89°), and lower back (34.42°±4.20°). The kneeling posture showed intermediate muscle activation, the slowest IMF decline for the erector spinae in the lower back (−0.005±0.008) Hz per unit time (0.128s), and the joint angles were closest to neutral. The task performance results were also superior in the kneeling posture. Regarding cognitive load, no significant differences were found for most biomechanical indicators, except for subjective cognitive load scores, neck flexion, and shoulder external rotation angles. Conclusion In assembly tasks performed at hand functional height, kneeling results in moderate biomechanical load on the neck, shoulders, and lower back while also improves task performance compared to squatting and forward bending. Additionally, no significant effects of cognitive load under the 2back condition on biomechanical load are observed.

Tissue-resident memory T cells （T_RM cells） are a subset of memory T cells that reside in tissues， exhibit tissue specificity， and do not recirculate. When potential hazards threaten the liver， such as pathogen invasion （bacteria， viruses， etc.） and excessive autoimmune responses， T_RM cells are essential as the first line of immune defense， playing an important role in viral hepatitis， autoimmune liver disease， metabolic dysfunction-associated fatty liver disease， liver cirrhosis， and liver transplantation. Here， we present the immunophenotypes of T_RM cells in the liver and their surface markers and transcriptional profiles， aiming to clarify the role of T_RM cells in chronic liver diseases and explore their potential function as therapeutic targets in immunotherapy.

Objective To systematically evaluate the efficacy and safety of immune checkpoint inhibitors (ICIs) as first-line treatment for advanced non-small cell lung cancer (NSCLC). Methods PubMed, The Cochrane Library, and EMbase databases were searched for clinical randomized controlled trials (RCTs) of ICIs as first-line treatment for NSCLC patients. The search period was from database inception to January 2023. Quality evaluation was conducted using the improved Jadad scale, and meta-analysis was performed using RevMan 5.4 software. Results Twelve RCTs were included, all of which were assessed as high-quality literature, involving a total of 7 121 patients. Meta-analysis results showed that, compared with chemotherapy, ICIs as first-line treatment for NSCLC patients significantly improved median overall survival (OS) [HR=0.72, 95%CI (0.64, 0.80), P<0.001] and median progression-free survival (PFS) [HR=0.65, 95%CI (0.53, 0.78), P<0.001], and improved objective response rate (ORR) [RR=1.52, 95%CI (1.28, 1.79), P<0.001]. Subgroup analysis showed that, compared with the ICIs monotherapy group, the ICIs combination therapy group significantly improved OS, PFS, and ORR in NSCLC patients. In terms of safety, the risk of any grade treatment-related adverse events (TRAEs) and grade 3-5 TRAEs in the ICIs group was lower than that in the chemotherapy group. The incidence of TRAEs leading to treatment discontinuation was higher in the ICIs group than in the chemotherapy group. Subgroup analysis showed that the incidence of any grade, grade 3-5, and TRAEs leading to treatment discontinuation was higher in the immune combination therapy group than in the immune monotherapy group. Conclusion ICIs as first-line treatment for NSCLC patients can significantly improve OS, PFS, and ORR compared with chemotherapy. Compared to immune monotherapy, immune combination therapy can significantly improve the efficacy in NSCLC patients, but patients have a higher risk of TRAEs.

CONCLUSIONS Simulated traditional Chinese medicine pharmacy based on virtual simulation technology meets the learning needs of users and enhances the teaching effect of traditional Chinese medicine dispensing technology training.

Traditional Chinese medicines (TCMs) possess a rich historical background, unique theoretical framework, remarkable therapeutic efficacy, and abundant resources. However, the modernization and internationalization of TCMs have faced significant obstacles due to their diverse ingredients and unknown mechanisms. To gain deeper insights into the phytochemicals and ensure the quality control of TCMs, there is an urgent need to enhance analytical techniques. Currently, two-dimensional (2D) chromatography, which incorporates two independent separation mechanisms, demonstrates superior separation capabilities compared to the traditional one-dimensional (1D) separation system when analyzing TCMs samples. Over the past decade, new techniques have been continuously developed to gain actionable insights from complex samples. This review presents the recent advancements in the application of multidimensional chromatography for the quality evaluation of TCMs, encompassing 2D-gas chromatography (GC), 2D-liquid chromatography (LC), as well as emerging three-dimensional (3D)-GC, 3D-LC, and their associated data-processing approaches. These studies highlight the promising potential of multidimensional chromatographic separation for future phytochemical analysis. Nevertheless, the increased separation capability has resulted in higher-order data sets and greater demands for data-processing tools. Considering that multidimensional chromatography is still a relatively nascent research field, further hardware enhancements and the implementation of chemometric methods are necessary to foster its robust development.

Radiotherapy (RT) can potentially induce systemic immune responses by initiating immunogenic cell death (ICD) of tumor cells. However, RT-induced antitumor immunologic responses are sporadic and insufficient against cancer metastases. Herein, we construct multifunctional self-sufficient nanoparticles (MARS) with dual-enzyme activity (GOx and peroxidase-like) to trigger radical storms and activate the cascade-amplified systemic immune responses to suppress both local tumors and metastatic relapse. In addition to limiting the Warburg effect to actualize starvation therapy, MARS catalyzes glucose to produce hydrogen peroxide (H₂O₂), which is then used in the Cu⁺-mediated Fenton-like reaction and RT sensitization. RT and chemodynamic therapy produce reactive oxygen species in the form of radical storms, which have a robust ICD impact on mobilizing the immune system. Thus, when MARS is combined with RT, potent systemic antitumor immunity can be generated by activating antigen-presenting cells, promoting dendritic cells maturation, increasing the infiltration of cytotoxic T lymphocytes, and reprogramming the immunosuppressive tumor microenvironment. Furthermore, the synergistic therapy of RT and MARS effectively suppresses local tumor growth, increases mouse longevity, and results in a 90% reduction in lung metastasis and postoperative recurrence. Overall, we provide a viable approach to treating cancer by inducing radical storms and activating cascade-amplified systemic immunity.

In this paper, the antitussive and expectorant activity of platycodin D (PD) were studied by constructing a mouse cough induced by concentrated ammonia water and a mouse trachea phenol red excretion model. The mechanism of antitussive and expectorant effect of PD was studied by metabolomics. The animal experiment was approved by the Animal Ethics Committee of Jiangxi University of Chinese Medicine (approval number: JZLLSC-20220739). Then mice were randomly divided into the normal, model, positive drug, PD low-dose, PD medium-dose and PD high-dose group. The antitussive and expectorant effects of PD were evaluated using a cough mouse model induced by concentrated ammonia water and a mouse tracheal phenol red excretion model, respectively. UHPLC-LTQ-Orbitrap-MS was used to identify the metabolites of mouse lung tissue, and multivariate statistical analysis method of orthogonal partial least squares discriminant analysis (OPLS-DA) was used for metabolites profile analysis. The differential metabolites were screened by variable projected importance value (VIP) and t-test results. Pathways for enrichment of differentiated metabolites were analyzed using the MetaboAnalyst platform. The comparative method was applied to analyze the differences in mechanisms of PD, Deapio-platycodin D (DPD) and total platycosides fraction. The results showed that PD at different concentrations could significantly prolong (P < 0.05) the incubation period of cough mice induced by ammonia water, reduce the coughs frequency, and significantly increase (P < 0.05) the amount of phenol red excretion in phenol red excretion model mice. PD could regulate 6 metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, linoleic acid metabolism, phenylalanine metabolism, glycerophospholipid metabolism, and tyrosine metabolism to exert antitussive effect. It could also regulate 8 metabolic pathways of linoleic acid metabolism, glyoxylic acid and dicarboxylic acid metabolism, glycerol phospholipid metabolism, citric acid cycle and arachidonic acid metabolism to exert an expectorant effect. However, only linoleic acid metabolism and glycerophospholipid metabolism could be regulated by the PD, total platycosides fraction and DPD, which may be ascribed to the structural difference of the platycosides and the interaction between platycosides and the intestinal microbiota. Functional analysis showed that these metabolic pathways are closely related to the regulatory mechanisms of anti-inflammatory response, immune function regulation, neurotransmitter release, cell signal transduction, energy metabolism and cell apoptosis. This study shows that PD possesses good antitussive and expectorant activities. In addition, the mechanism difference of PD, total platycosides fraction and DPD imply that the apiose in PD and the interaction between PD and intestinal microbiota could exert an important effect on the antitussive and expectorant mechanism of the platycosides.
