Esophageal cancer （EC） is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， as one of the key oncogenic pathways， can promote the cell cycle progression， proliferation， migration， and invasion， induce chemoresistance， and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine （TCM）， with the advantages of targeting multiple points with multiple components to delay cancer progression， can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum， spore powder of Ganoderma lucidum without spore coat， extract of Celastrus orbiculatus， root extract of Taraxacum， and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids， terpenoids， saponins， phenols， polysaccharides， alkaloids， and other compounds. TCM compound prescriptions with such effect include Qige San， Huqi San， Xuanfu Daizhetang， Tongyoutang and its decomposed prescriptions， Liujunzi Tang， and Xishenzhi Formula. In addition， TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions， aiming to provide reference for the research and clinical application of new drugs for EC.

Achondroplasia (ACH) is a common inherited skeletal dysplasia (inherited dwarfism) that compromises quality of life across the lifespan. In 2021, vosoritide became the first approved precision therapy for ACH and is now available in more than 40 countries. Compared with prior symptomatic measures, vosoritide has demonstrated favorable efficacy and a reassuring safety profile. Nevertheless, existing international ACH guidelines largely emphasize complication management and symptomatic care, and there is no unified consensus on pharmacologic therapy. To address this gap, an international expert group developed the International Consensus Guidelines for the Implementation and Monitoring of Vosoritide Therapy in Patients with Achondroplasia providing systematic recommendations that span the continuum of care - from initial patient contact and pre-treatment assessment to medication counseling, injection training, and long-term outcome monitoring. These recommendations complement and refine current management and nursing protocols for individuals with ACH and offer practical guidance for clinicians across diverse regions. This article highlights key elements of the guideline to provide evidence-based support and clinical direction for healthcare professionals in China treating children with ACH using vosoritide.

OBJECTIVE To investigate the effect of pharmaceutical services guided by root cause analysis （RCA） in a problem-oriented manner combined with knowledge-attitude-practice （KAP） theory on reducing the incidence of protocol violations of investigational medicinal products in pediatric clinical trials. METHODS A total of 617 participants from 69 drug clinical trial projects conducted in our hospital from January 2016 to December 2020 were selected as the control group， and 868 participants from 72 drug clinical trial projects from January 2022 to December 2025 as the observation group. RCA was performed on the protocol violations of investigational medicinal product in the control group to identify the types and underlying causes. The control group received routine pharmaceutical services for drug clinical trials， while the observation group was provided with precision pharmaceutical services from the three dimensions of knowledge， attitude and practice on the basis of routine pharmaceutical services， according to the root causes identified by RCA. The occurrence of investigational medicinal products protocol violations was compared between the two groups. RESULTS The total incidence of protocol violations of investigational medicinal products， as well as the incidences of minor and major protocol violations， were all significantly lower in the observation group than in the control group （ P ＜0.001）. The main types of protocol violations in both groups included missed/under-/over-dosing of medications， non-adherence to administration time， failure to adjust dosage as required， and combined medication/vaccination in violation of the protocol. Regarding the responsible subjects of protocol violations， the incidences of protocol violations attributed to participants and their guardians as well as investigators and accidental factors were significantly lower in the observation group than in the control group （ P ＜0.001， P ＜0.001， P ＝0.025）. However， there were no statistically significant differences in the incidences of protocol violations caused by sponsor-related reasons between the two groups （ P ＞0.05）. CONCLUSIONS Pharmaceutical services led by pharmacists， based on problem-oriented RCA and combined with KAP theory， can effectively reduce the protocol violations of investigational medicinal products rate in pediatric clinical trials， thereby safeguarding the safety and rights of study participants.

BACKGROUND:Studies have shown that disorders of mineral metabolism may be responsible for premature aging and that the kl/FGF23 axis plays an important role in mineral metabolism.OBJECTIVE:To explore the effect of long-term endurance exercise on the kl/FGF23 axis in naturally aging mice,and to observe the impact of long-term endurance exercise on calcium and phosphorus metabolism,so as to provide a reference for the influence of long-term endurance exercise on natural aging.METHODS:Twenty-two 5-week-old SPF male balb/c mice were randomly divided into three groups:young and quiet control group,natural aging quiet group and natural aging exercise group.Mice in the young and quiet control group were then killed immediately.Mice in the natural aging quiet group were raised normally until 60 weeks of age.Mice in the natural aging exercise group were subjected to adaptive exercise for 1 week,followed by the maximum running speed test.The official exercise speed was set at 70％of the maximum running speed,and exercise was performed on Mondays,Wednesdays,and Fridays for 50 minutes each.Maximum running speed was retested at 8-week intervals to adjust the official exercise speed until the age of 60 weeks.(3)Enzyme-linked immunoassay was used to measure the levels of femoral fibroblast growth factor 23,renal fibroblast growth factor receptor 1,1α-hydroxylase,and serum 1,25(OH)2D3.RESULTS AND CONCLUSION:(1)Compared with the young and quiet control group,serum calcium and phosphorus levels in natural aging quiet group had no significant changes(P＞0.05),but bone calcium and phosphorus levels were significantly reduced(P＜0.01).Compared with the natural aging quiet group,the serum phosphorus level was significantly reduced(P＜0.05),the serum calcium level did not change(P＞0.05),and bone calcium and phosphorus levels were significantly increased in the natural aging exercise group(P＜0.05).(2)Compared with the young and quiet control group,the level of fibroblast growth factor 23 in the femur of the natural aging quiet group was significantly increased(P＜0.05).Compared with the natural aging quiet group,the level of fibroblast growth factor 23 in the femur of the natural aging exercise group was reduced,but it was not statistically significant(P＞0.05).(3)Compared with the young and quiet control group,the renal Klotho protein expression,the renal fibroblast growth factor receptor 1,1α-hydroxylase,and serum 1,25(OH)2 D3 levels in the natural aging quiet group were significantly decreased(P＜0.05,P＜0.01).Compared with the natural aging quiet group,the levels of the above-mentioned indicators were significantly increased in the natural aging exercise group(P＜0.05,P＜0.01).To conclude,long-term endurance exercise can regulate Klotho protein and fibroblast growth factor 23 through the kl/FGF23 axis,thereby affecting the expression of 1α-hydroxylase and the level of 1,25(OH)2D3,and further regulating the body's calcium and phosphorus metabolism,especially phosphate metabolism.This indicates that long-term endurance exercise can delay the natural aging of the body through the kl/FGF23 axis.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

OBJECTIVE To evaluate the effect of bundled property management under multidisciplinary coopera-tion mode on prevention and control of multidrug-resistant organisms(MDROs)in intensive care units(ICUs)and explore the evidence-based methods for prevention and control of MDROs.METHODS A control study before and after the same time period was designed,the post-intervention period was 2024 when the bundled measures were fully implemented,and the pre-intervention period was 2023.Totally 8 ICUs of general and special depart-ments of a three-A hospital in Hubei Province were recruited as research subjects,the multidisciplinary coopera-tion team was established,the bundled management measures were introduced to optimize the quality of property cleaning work.The quality of service of the property cleaning work was evaluated through surveillance of hospital-associated infections and environmental hygiene surveillance before and after the bundled measures were imple-mented.RESULTS The isolation rate of MDROs from object surfaces of ICU environment declined from 0.34％to 0.10％after the bundled management measures under multidisciplinary cooperation model were implemented(P＜0.05).The incidence of MDROs hospital-associated infections was reduced from 0.07％to 0.03％(P＜0.05);the isolation rate of MDROs from patients decreased from 14.68％to 12.69％(P＜0.05);the performance as-sessment score of the cleaning staff was raised from(85.56±7.21)points to(91.06±3.07)points,however,there was no significant difference.The hand hygiene compliance rate of the cleaning staff was raised from 42.86％to 68.52％(P＜0.05).The positive rate of random ATP fluorescent test for environmental object surfaces de-clined from 25.41％to 10.05％(P＜0.05).Other environmental hygiene indexes for the cleaning and disinfection effects were improved in varying degrees.CONCLUSION The bundled management measures under multidiscipli-nary cooperation mode boost the property service quality,enhance the cleaning staff's awareness of disinfection,prevention and control,reduce the isolation rate of MDROs in environment,and thus decrease the incidence of MDROs hospital-associated infections and prevent the transmission.

Objective:In response to the current situation where Investigator-Initiated Trial (IIT) management system of pediatric medical institutions in our country is inadequate and the management of high-risk projects needs to be strengthened, a pediatric hospital in Beijing has been selected as a pilot to develop a system and process suitable for IIT management. We aim to explore personalized management models for different types of research projects, especially high-risk ones, to improve the quality of pediatric IIT, reduce research risks, and enhance management efficiency.Methods:By analyzing the current management situation of high-risk pediatric IIT, optimization strategies were proposed to improve the internal IIT project management system and processes of the pilot unit, and effective management measures are promoted.Results:By revising the IIT project management system, improving the project application and approval processes, strengthening process quality control and personnel training, the risk control and quality supervision of such projects had been enhanced, thereby improving project quality and ensuring the rights and interests of research participants.Conclusions:After the pilot unit trialed a series of management measures for high-risk IIT projects, researchers' risk awareness has significantly increased, and project quality has been effectively improved. The Results provide a reference and model for peers in establishing management rules and also offer theoretical and practical foundations for improving the management system of high-risk clinical research.

OBJECTIVES: To investigate the role of activating transcription factor 3 (ATF3) in atherosclerotic plaques for regulating inflammatory responses during atherosclerosis (AS) progression. METHODS: Human coronary artery specimens from autopsy cases were examined for ATF3 protein expression and localization using immunofluorescence staining and Western blotting. Apolipoprotein E-deficient (ApoE^-/-) mouse models of AS induced by high-fat diet (HFD) feeding for 12 weeks were subjected to tail vein injection of adeno-associated virus serotype 9 (AAV9) to knock down ATF3 expression. After an additional 5 weeks of HFD feeding, the mice were euthanized for analyzing structural changes of the aortic plaques, and the expression levels of ATF3, inflammatory factors (CD45, CD68, IL-1β, and TNF-α), and NF-κB pathway proteins (P-IKKα/β and P-NF-κB p65) were detected. In the cell experiment, THP-1-derived foam cells were transfected with an ATF3-overexpressing plasmid or an ATF3-specific siRNA to validate the relationship between ATF3 and NF‑κB signaling. RESULTS: In human atherosclerotic plaques, ATF3 expression was significantly elevated and partially co-localized with CD68. ATF3 knockout in ApoE^-/- mice significantly increased aortic plaque volume, upregulated the inflammatory factors, enhanced phosphorylation of the NF‑κB pathway proteins, and increased the expressions of VCAM1, MMP9, and MMP2 in the plaques. In THP-1-derived foam cells, ATF3 silencing caused activation of the NF‑κB pathway, while ATF3 overexpression suppressed the activity of the NF-κB pathway. CONCLUSIONS AS promotes ATF3 expression, and ATF3 deficiency exacerbates AS progression by enhancing plaque inflammation via activating the NF-κB pathway, suggesting the potential of ATF3 as a therapeutic target for AS.

Objective:To mine the risk signal of acute kidney injury (AKI) induced by different oral anticoagulant drugs (OACs) in various populations and provide a reference for clinical use of OACs.Methods:Reports of AKI induced by OACs and non-OACs in the US Food and Drug Administration Adverse Event Reporting System database from the 1st quarter of 2004 to the 3rd quarter of 2023 were collected. The relationship between the drugs mentioned above and the AKI in patients were analyzed by methods of reporting odds ratio (ROR) and Bayesian confidence propagation neural network (BCPNN). When the number of reports of the target adverse event (AE) for the target drug was ≥3, and the lower limit of the 95% confidence interval ( CI) of ROR was >1 or the lower limit of the 95% CI of the information component ( IC025) was >0, it indicated a statistically significant association between the target drug and the target AE. Results:A total of 12 402 AKI reports related to OACs were collected, including 1 313 for warfarin, 3 086 for dabigatran, 4 730 for rivaroxaban, 2 918 for apixaban, and 365 for edoxaban; 454 378 AKI reports were related to non-OACs. The overall analysis of OACs showed an ROR (lower limit of 95% CI) of 1.791 (1.759) and an IC ( IC025) of 0.813 (0.787) for AKI caused by OACs. Analysis of individual OACs showed that warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban all posed risks for AKI, with ROR (lower limit of 95% CI) of 1.220(1.156), 2.386(2.302), 2.044(1.986), 1.375(1.326), 3.003(2.706), respectively, and IC ( IC025) of 0.284(0.204), 1.231(1.178), 1.010(0.968), 0.452(0.399), 1.560(1.407), respectively. Edoxaban had the highest ROR and IC values, while warfarin had the lowest. Subgroup analysis showed that in the <18 years subgroup, neither warfarin nor rivaroxaban showed a risk of AKI; the ROR method did not show dabigatran to have a risk of AKI, but the BCPNN method did. In the 18-45 years subgroup, both methods showed that apixaban did not have a risk of AKI, while all other OACs did. In the 45-64 years subgroup, all OACs showed a risk of AKI. In the ≥65 years subgroup, warfarin and apixaban posed risks for AKI. Gender subgroup analysis showed that both methods indicated a risk of AKI with warfarin in males; all OACs showed a risk of AKI in females. Conclusions:OAC has a statistically significant risk of AKI, among which edoxaban has the highest risk intensity and warfarin has the lowest. Different OACs have different risks of AKI in patients with different ages.
