OBJECTIVE To standardize the management of patients’ self-carried medicines dispensed by Pharmacy Intravenous Admixture Services （PIVAS） of our hospital， improve the quality of medical care， and ensure the safety of patients’ medication. METHODS Based on evidence-based methodology， the research literature of domestic medical institutions on the management of patients’ self-carried medicines was systematically searched and analyzed， and the data on the use of patients’ self- carried medicines in our hospital from February to April 2023 were extracted based on our hospital’s information system. A fishbone diagram of the difficulties in constructing patients’ self-carried medicines within PIVAS of our hospital was drawn through brainstorming， thereby establishing a refined whole-process management system for patients’ self-carried medicines in PIVAS. The effectiveness of the system was evaluated through the indicators， including dispensing volume， error rate， and so on. RESULTS & CONCLUSIONS A total of 15 papers were included， covering descriptive studies on the reasons for the use of patients’ self- carried medicines， current status of their use， management system， management methods， management suggestions. There were 12 clinical departments in our hospital with a high proportion of patients using self-carried medicines， among which the pediatric neurology department had the most use of patients’ self-carried medicines， accounting for 10.65%. In terms of dosage form， injectable drugs accounted for 13.68%， all of anticancer drug were uniformly dispensed by our hospital’s PIVAS. PIVAS in our hospital had successfully constructed the management system for dispensing patients’ self-carried medicines， which included the processes of drug reception and preservation， medical document retention， doctor’s order review， drug placement， dispensing， review and transportation. After the implementation of the system， from May 2023 to October 2024， our hospital’s PIVAS dispensed 654 bags of patients’ self-carried medicines in total，with a monthly average of 36 bags. Zero error management 5）；was realized for all patients’ self-carried medicines. The system operates stably and effectively， thereby ensuring the high-quality dispensing of patients’ self-carried medicines in PIVAS of our hospital.

Triple-negative breast cancer is therapeutically challenging due to the low expression of tumor markers and 'cold' tumor immunosuppressive microenvironment. Here, we present a dual-targeting peptide-drug conjugate (PDC) for tumor inhibition. Our PDC efficiently and selectively delivers cytotoxic Monomethyl Auristatin E (MMAE) into tumor cells via C-X-C chemokine receptor type 4 (CXCR4) and folate receptor 1 (FOLR1) for synergistic inhibition of growth and metastasis. Our results show that the dual-targeting PDC has potent antitumor activity in cultured human cells and several murine transplanted tumor models without apparent toxicity. The combination of dual-targeting PDC and radiotherapy modulates the tumor immunosuppressive microenvironment by increasing CD8⁺ T cell infiltration and attenuating the proportion of myeloid-derived suppressor and regulatory T cells. Therefore, our dual-targeting PDC represents a promising new strategy for cancer therapy that rebalances the immune system and promotes tumor regression.

Objective To analyze the possible mechanism and drug treatment plan of diffuse alveolar hemorrhage induced by human granulocyte colony-stimulating factor injection, point out medication risks and provide reference for medical treatment and pharmaceutical care of such patients. Methods The abnormal lung conditions of a patient treated with human granulocyte colony-stimulating factor injection was found by clinical pharmacists, who participated in clinical diagnosis and treatment by analyzing of adverse drug reactions, optimization of medical treatment and pharmaceutical care. Results Diffuse alveolar hemorrhage was likely an adverse drug reaction caused by human granulocyte colony-stimulating factor injection. The physician discontinued the medication immediately and provided treatment such as oxygen inhalation, high-dose hormone shock, plasma exchange, etc. The patient’s oxygen saturation was improved, alveolar bleeding was decreased, and the condition was improved. Conclusion Clinical pharmacists participate in patients’ medication treatment, carry out pharmaceutical guardianship, and assist physicians in adjusting treatment plans, which could contribute to the effectiveness and safety of patient treatment.

Objective:To investigate the genetic and evolutionary characteristics of hemagglutinin (HA) and neuraminidase (NA) genes of influenza B/Victoria (BV) virus in Xi′an city from 2019 to 2023.Methods:Twenty-five BV strains isolated from the Xi′an influenza surveillance network laboratory between 2019 and 2023 were collected. The HA and NA genes were sequenced using MiniSeq high-throughput sequencing platform. An evolutionary tree was constructed using bioinformatics software to analyze homology and mutation sites, and to predict N-glycosylation sites online. The antigenicity of the strains was analyzed through hemagglutination inhibition tests.Results:The BV influenza in Xi′an exhibited a distinct seasonal transmission pattern from 2019 to 2023, with peak prevalence occurring during the winter and spring seasons. The evolutionary analysis of the HA genes shows that the strains from Xi′an in 2019 belong to the V1A.3 branch, and the strains from 2021 to 2023 belong to the V1A.3a.2 branch. Analysis of antigenic sites showed that there were variations in 6 sites of 3 antigenic determinants in the HA proteins of the BV strains from 2021-2022 compared to 2019, and 2 sites of 1 antigenic determinant changed in the HA proteins in 2023 compared to 2021-2022. The evolutionary analysis of the NA genes indicates that the BV strains from Xi′an in 2019 belong to the A. 1.1 branch. By 2021 and 2022, it had evolved into the A. 1.2 clade, and by 2023, it had further evolved into the B clade and its derivatives, with no strains showing mutations associated with resistance to NA inhibitors. Antigenic analysis indicated that the majority of BV strains in Xi′an were similar to the strains included in the vaccine composition. Furthermore, glycosylation analysis showed that the potential N-glycosylation sites in the HA proteins of BV strains from 2021-2023 were reduced by one compared to those from 2019, and only a few strains from 2023 displayed alterations in the potential N-glycosylation sites of the NA proteins.Conclusions:The HA and NA genes of the BV strains from 2019 to 2023 are continuously mutating and evolving into new branches. Since 2021, V1A.3a.2 has become the dominant evolutionary branch of the HA genes, while the evolutionary branches of the NA genes from 2019 to 2023 have been continuously changing.

With a global rise in morbidity rates， obesity has become a pressing public health issue. With increased adipocyte number and volume as the main characteristics， obesity is also manifested by metabolic disorders to varying degrees. At the same time， obesity is a risk factor for diabetes， hypertension， stroke， cancer， and cardiovascular diseases， imposing burdens on society and families. Influenced by lifestyle， environment， behavior， and genetics， obesity is caused by the interaction of many factors， and its pathological process is complex， involving inflammation， autophagy， and intestinal dysbiosis. The mitogen-activated protein kinase （MAPK） cascade reaction， a pivotal signaling pathway， plays a crucial role in cellular processes such as proliferation， differentiation， apoptosis， and stress responses. Both Chinese and international studies indicate that the MAPK signaling pathway can effectively regulate obesity through various pathways， including the modulation of adipocyte differentiation and apoptosis， appetite control， and inflammation improvement. Moreover， traditional Chinese medicine （TCM） has demonstrated significant efficacy in preventing and treating obesity， leveraging advantages such as multiple targets， diverse components， and minimal adverse effects. Research indicates that the MAPK signaling pathway is a primary focus of TCM regulation in this context， although a systematic review in this field is currently lacking. Therefore， this paper， by reviewing the latest Chinese and international research， provided a concise overview of the basic structure of the MAPK pathway， with a specific emphasis on recent progress in TCM interventions targeting the MAPK pathway for obesity treatment. The results indicate that regulating adipose tissue formation， differentiation， and thermogenesis， reducing inflammation and oxidative stress levels， and improving insulin sensitivity and metabolic disorders seem to be the main ways for TCM to regulate the MAPK pathway to prevent and treat obesity. However， it is necessary to find more research methods and explore potential mechanisms underlying TCM formulations based on the MAPK pathway for obesity prevention and treatment.

Objective:To investigate the prevalence of enterovirus 71 (EV71) and the genetic characteristics of VP1 region in common hand, foot and mouth disease (HFMD) cases in Shenzhen from 2016 to 2022.Methods:Throat swabs from mild HFMD in Shenzhen sentinel hospitals were collected from 2016 to 2022. A total of 38 EV71-positive samples were screened from these throat swabs and were sequenced. Then, the VP1 sequence of these EV71-positive samples were analyzed for their phylogenetic evolution by bioimformatics software DNAStar and MEGA 6.Results:From 2016 to 2022, the number of EV71 infections among HFMD patients in Shenzhen sentinel hospitals decreased from 136 in 2016 to 0 in 2022. The mumber of EV71 infections in 2018 and 2019 decreased by 96.3%(257/267) compared to that in 2016 and 2017. From 2020 to 2022, the number of EV71 infections decreased to 0. During this period, the EV71 vaccination rate among HFMD patients increased from 6.4% to 39.6%; Evolutionary analysis showed that the nucleotide homology and amino acid homology between 38 EV71 sample strains in Shenzhen from 2016 to 2022 were 91.8%-99.9% and 98.3%-100.0%, all belonging to the C4a subgenotype; Among them, 26 strains wene local epidemic strains, and 11 strains were imported from other provinces, with a close genetic relationship with epidemic strains in Hainan, Yunnan, Sichuan, Tianjin, Henan, Jilin, and other places. One strain from 2017 had the closest genetic relationship with the US epidemic strain OP207969-USA-2017. Further comparing the EV71 epidemic strains in Shenzhen from 2016 to 2022 and EV71 severe strains, it was found that the EV71 strains in Shenzhen carried four amino acid mutation sites related to severe condition, named R22H, K43R, I249V and T289A.Conclusions:The EV71 epidemic strains in Shenzhen from 2016 to 2022 all belong to the C4a subgenotype, and the number of EV71 infection shows a downward trend with the increase of vaccine coverage rate. At the same time, the distribution of EV71 virus strains in Shenzhen shows a significant decrease in local strains and a predominance of imported strains. There are a total of four amino acid mutation sites associated with severe cases in the EV71 sample strains in Shenzhen from 2016 to 2022. Among them, 22R and 289T are located at the N and C ends of VP1, which are related to EV71 adsorption and targeting cells. The 43R site is associated with binding ability to Annexin2 protein, which enhances cell binding ability.
