OBJECTIVE To establish a Chinese drug-related problem (DRP) classification system applicable to pharmacist-led pharmaceutical care in China, providing pharmacists with an effective and practical tool for pharmaceutical care. METHODS A multi-stage process was employed to construct the DRP classification system, including literature review and analysis, comparison of existing classification systems, refinement of classification items and framework development, two rounds of standard case validation, expert discussion, and system revision. The Fleiss′ kappa test was used to calculate the consistency coefficient κ, assessing the reliability of pharmacists participating in evaluating the classification system. An electronic questionnaire comprising six items was employed to evaluate the system’s applicability. RESULTS The constructed Chinese DRP classification system comprised six sections [problem(including potential problems), DRP evaluation, cause (including possible causes of potential problems), intervention, acceptance of intervention and DRP status], with 24 primary codes and 96 secondary codes. In the first round of case validation, κ values exceeded 0.4 for all sections except “intervention” and “DRP status”. In the second round, κ values exceeded 0.4 for all sections. In the applicability evaluation of the classification system, positive ratings (“strongly agree” or “agree”) exceeded 85% for all items. Specifically, positive ratings for“the classification system can provide appropriate category selection”,“ the classification system is comprehensive”,“ the classification system is convenient to use” and “the classification system is highly satisfactory” exceeded 92%. CONCLUSIONS The Chinese DRP classification system developed demonstrates both high reliability and applicability, providing an effective and practical classification tool for pharmacists in China to conduct pharmaceutical care.

Glioma represents the most prevalent malignant tumor of the central nervous system, with chemotherapy serving as an essential adjunctive treatment. However, most chemotherapeutic agents exhibit limited ability to penetrate the blood-brain barrier (BBB). This study introduced a novel dual-targeting strategy for glioma therapy by modulating the formation of nanobody-driven protein coronas to enhance the brain and tumor-targeting efficiency of hydrophobic cisplatin prodrug-loaded lipid nanoparticles (C8Pt-Ls). Specifically, nanobodies (Nbs) with fibrinogen-binding capabilities were conjugated to the surface of C8Pt-Ls, resulting in the generation of Nb-C8Pt-Ls. Within the bloodstream, Nb-C8Pt-Ls could bound more fibrinogen, forming the protein corona that specifically interacted with LRP-1, a receptor highly expressed on the BBB. This interaction enabled a "Hitchhiking Effect" mechanism, facilitating efficient trans-BBB transport and promoting effective brain targeting. Additionally, the protein corona interacted with LRP-1, which is also overexpressed in glioma cells, achieving precise tumor targeting. Computational simulations and SPR detection clarified the molecular interaction mechanism of the Nb-fibrinogen-(LRP-1) complex, confirming its binding specificity and stability. Our results demonstrated that this strategy significantly enhanced C8Pt accumulation in brain tissues and tumors, induced apoptosis in glioma cells, and improved therapeutic efficacy. This study provides a novel framework for glioma therapy and underscores the potential of protein corona modulation-based dual-targeting strategies in advancing treatments for brain tumors.

General anesthesia, pivotal for surgical procedures, requires precise depth monitoring to mitigate risks ranging from intraoperative awareness to postoperative cognitive impairments. Traditional assessment methods, relying on physiological indicators or behavioral responses, fall short of accurately capturing the nuanced states of unconsciousness. This study introduces a machine learning-based approach to decode anesthesia depth, leveraging EEG data across different anesthesia states induced by propofol and esketamine in rats. Our findings demonstrate the model's robust predictive accuracy, underscored by a novel intra-subject dataset partitioning and a 5-fold cross-validation method. The research diverges from conventional monitoring by utilizing anesthetic infusion rates as objective indicators of anesthesia states, highlighting distinct EEG patterns and enhancing prediction accuracy. Moreover, the model's ability to generalize across individuals suggests its potential for broad clinical application, distinguishing between anesthetic agents and their depths. Despite relying on rat EEG data, which poses questions about real-world applicability, our approach marks a significant advance in anesthesia monitoring.

ObjectiveTo explore the diagnostic-therapeutic course and epidemiological characteristics of the first imported kala-azar case reported in Changning District of Shanghai, so as to provide references for early detection, timely diagnosis, and effective management of the kala-azar cases in non-epidemic areas. MethodsIn 2025, a comprehensive epidemiological investigation and a complete collection of clinical records of one kala-azar patient imported from other provinces reported by a medical institution in this city were conducted. The source of infection, process of diagnosis and treatment, and clinical outcome of the case were systematically analyzed. ResultsThe case was a male migrant worker from Shanxi Province currently residing in Shanghai. In June 2023, the patient had a history of exposure to mosquito bites during his stay in a kala-azar endemic area. The initial onset occurred in December 2023, with clinical manifestations including unexplained fever accompanied by leukopenia, and subsequently gradually developed night sweats and fatigue during the following months. In June 2024, the patient self-perceived significant weight loss, and physical examination revealed hepatomegaly and splenomegaly, leading to a diagnosis of hemophagocytic syndrome (HPS). Throughout the whole course of the illness, the patient sought treatment at hematology departments of several hospitals multiple times, where he was managed as a case of HPS. In January 2025, a large number of Leishmania donovani were detected in the patient's bone marrow smear, confirming kala-azar. After 2 weeks of standardized treatment with amphotericin B liposomal, there was significant improvement. Combined with the epidemiological investigation, it was speculated that the incubation period of this case was about 6 months, whereas the interval from initial onset to definite diagnosis was approximately 14 months. ConclusionKala-azar has atypical early clinical symptoms, which are prone to confusion with HPS. For patients with recurrent unexplained fever accompanied by peripheral cytopenias, hepatomegaly and splenomegaly, medical institutions should consider the possibility of infectious diseases. Close collaboration between medical institutions and centers for disease control and prevention is essential to conduct a detailed epidemiological investigation and laboratory screening, ensuring confirmed cases receive standardized treatment.

OBJECTIVE:
To summarize the gene therapy strategies for neurofibromatosis type 1 (NF1) and related research progress.
METHODS:
The recent literature on gene therapy for NF1 at home and abroad was reviewed. The structure and function of the NF1 gene and its mutations were analyzed, and the current status as well as future prospects of the transgenic therapy and gene editing strategies were summarized.
RESULTS:
NF1 is an autosomal dominantly inherited tumor predisposition syndrome caused by mutations in the NF1 tumor suppressor gene, which impair the function of the neurofibromin and lead to the disease. It has complex clinical manifestations and is not yet curable. Gene therapy strategies for NF1 are still in the research and development stage. Existing studies on the transgenic therapy for NF1 have mainly focused on the construction and expression of the GTPase-activating protein-related domain in cells that lack of functional neurofibromin, confirming the feasibility of the transgenic therapy for NF1. Future research may focus on split adeno-associated virus (AAV) gene delivery, oversized AAV gene delivery, and the development of new vectors for targeted delivery of full-length NF1 cDNA. In addition, the gene editing tools of the new generation have great potential to treat monogenic genetic diseases such as NF1, but need to be further validated in terms of efficiency and safety.
CONCLUSION
Gene therapy, including both the transgenic therapy and gene editing, is expected to become an important new therapeutic approach for NF1 patients.

Peptides are a particular molecule class with inherent attributes of some small-molecule drugs and macromolecular biologics, thereby inspiring continuous searches for peptides with therapeutic and/or agrochemical potentials. However, the success rate is decreasing, presumably because many interesting but less-abundant peptides are so scarce or labile that they are likely 'overlooked' during the characterization effort. Here, we present the biochemical characterization and druggability improvement of an unprecedented minor fungal RiPP (ribosomally synthesized and post-translationally modified peptide), named acalitide, by taking the relevant advantages of metabolomics approach and disulfide-bridged substructure which is more frequently imprinted in the marketed peptide drug molecules. Acalitide is biosynthetically unique in the macrotricyclization via two disulfide bridges and a protease (AcaB)-catalyzed lactamization of AcaA, an unprecedented precursor peptide. Such a biosynthetic logic was successfully re-edited for its sample supply renewal to facilitate the identification of the in vitro and in vivo antiparkinsonian efficacy of acalitide which was further confirmed safe and rendered brain-targetable by the liposome encapsulation strategy. Taken together, the work updates the mining strategy and biosynthetic complexity of RiPPs to unravel an antiparkinsonian drug candidate valuable for combating Parkinson's disease that is globally prevailing in an alarming manner.

Objective:To determine the effects of early enteral nutrition (EEN) on the short-term prognosis of patients receiving veno-arterial extracorporeal membrane oxygenation (VA-ECMO).Methods:61 patients admitted to the Coronary Care Unit (CCU) of Henan Provincial Peoples' Hospital from February 2022 to March 2023 to receive VA-ECMO treatment were selected as the study objects according a retrospective survey. The patients were divided into an achievement group ( n=34) and a non-achievement group ( n=27) based on whether the feeding amount reached 70% or over of the target calories (25kcal/kg.d) on the 7th day of ECMO treatment. The general characteristics, disease information, complications, and prognosis between the two groups after ICU admission were recorded and compared. A multivariable Cox proportional hazards model was used to evaluate the impact of various factors on clinical outcomes. Kaplan-Meier analysis was used to draw survival curves for the two groups, and the predictive value of the ratio of actual EN intake to target energy was calculated by plotting the ROC curve. Results:A total of 61 patients were included, with an overall in-hospital mortality rate of 50.82% (31/61), with 32.35% (11/34) in the achievement group, and 70.37% (19/27) in the non-achievement group. Cox regression analysis revealed that the occurrence of hypoxic-ischemic encephalopathy (HR=0.341, 95% CI:0.119-0.975), ECOM weaning failure ( HR=0.269, 95% CI:0.111-0.651), and achieving EN targets on the 7th day of VA-ECMO treatment ( HR=10.891, 95% CI:1.178-100.718) were independent factors for patient mortality during hospitalization. The ROC curve for the percentage of EN achievement on the 7th day of VA-ECMO treatment and in-hospital mortality showed an area under the curve of 0.755, with a cutoff value of 0.73. Conclusion:The presence of ischemic hypoxic encephalopathy, ECOM weaning failure, and whether achieving EN targets or not is closely related to the prognosis of VA-ECMO patients. Patients who achieving EN targets of over 73% had the lowest in-hospital mortality rate. Therefore, more attention should be paid to the energy intake of VA-ECMO patients to reduce their risk of mortality.
