ObjectiveTo investigate whether the effect of Taohong Siwutang on cerebral ischemia-reperfusion （CIRI） injury in rats is related to the regulation of astrocyte polarization and explore the related mechanism. MethodsEighty-four male SD rats were randomly assigned to the following groups： A sham operation group， a model group， Taohong Siwutang treatment groups （low dose， medium dose， and high dose）， ligustrazine phosphate tablet （LPT） group， and AG490 group. All groups， except for the sham operation group， underwent middle cerebral artery occlusion/reperfusion （MCAO/R） modeling and were treated for seven days. The neurological impairment was evaluated using the Longa score. The volume of cerebral infarction was assessed through 2，3，5-triphenyltetrazolium chloride （TTC） staining. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot analyses were performed to analyze the mRNA and protein expression levels of cortical complement 3 （C3）， S100 calcium-binding protein A10 （S100A10）， Janus kinase 2 （JAK2）， and signal transducer and activator of transcription 3 （STAT3）. Additionally， protein expression levels of vascular endothelial growth factor-A （VEGF-A） were assessed， and the mRNA expression levels of inflammatory factors， including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α）， were evaluated. Glial fibrillary acidic protein （GFAP） and C3， S100A10 and Co-localization was detected via immunofluorescence double staining. Lastly， VEGF expression levels were measured using enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham operation group， the model group showed a significant increase in cerebral infarction volume and neurological impairment （P<0.01）. C3 protein levels were elevated， while S100A10 levels were decreased. Pathway-related markers were significantly upregulated （P<0.05， P<0.01）， and VEGF-A protein levels were significantly reduced （P<0.01）. The mRNA expression of inflammatory factors was significantly upregulated （P<0.01）. Co-localization analysis showed significantly increased GFAP and C3 fluorescence intensity （P<0.01） and greatly decreased GFAP and S100A10 fluorescence intensity （P<0.01）. Additionally， VEGF content was significantly elevated （P<0.01）. Compared with the model group， medium- and high-dose Taohong Siwutang and LPT groups exhibited a significant reduction in cerebral infarction volume and neurological impairment （P<0.01）. Groups treated with low， medium， and high doses of Taohong Siwutang and LPT group exhibited a decrease in C3 protein expression levels and an increase in S100A10 expression levels （P<0.01）. In the high-dose Taohong Siwutang and AG490 groups， both protein and mRNA expression of C3 and pathway-related markers were significantly downregulated （P<0.05， P<0.01）， while S100A10 expression and VEGF-A protein levels were significantly increased （P<0.01）. Additionally， the mRNA expression levels of inflammatory factors were significantly reduced （P<0.01）. The co-localization fluorescence intensity of GFAP and C3 significantly decreased （P<0.01）， while that of GFAP and S100A10 greatly increased （P<0.01）. Furthermore， VEGF content exhibited a marked elevation （P<0.01）. ConclusionTaohong Siwutang exerts a protective effect in rats with cerebral CIRI injury. The underlying mechanism is associated with the downregulation of the JAK2/STAT3 signaling pathway， promotion of A2-type astrocyte polarization， reduction of inflammatory factor release， and enhancement of VEGF production.

OBJECTIVE To explore the significance of pharmaceutical care through the diagnosis and treatment of a patient with exogenous insulin autoimmune syndrome （EIAS）， combined with the analysis of literature reports. METHODS Clinical pharmacist participated in the diagnosis and treatment process of one case of EIAS. Based on the characteristics of the patient’s condition， the pharmacist provided medication suggestions and formulated pharmaceutical monitoring measures. At the same time， the pharmacist searched for relevant literature on insulin autoimmune syndrome （IAS） and EIAS， extracted data （gender， age， occurrence time， laboratory tests， clinical symptoms， intervention and outcome）， and conducted analysis. RESULTS Based on the patient’s medication information in the past 3 years， clinical pharmacist determined that the EIAS was likely caused by insulin aspartate 30. The clinician adopted the clinical pharmacist’s suggestion to discontinue insulin and switch to oral hypoglycemic drugs. The patient improved after treatment. The literature analysis showed that among the 257 patients with IAS reported， 212 cases were caused by drugs； among them， 23 cases were caused by lipoic acid， and 56 cases were caused by exogenous insulin. There were no significant differences in age， glycosylated hemoglobin， and body mass index between the two groups. The lowest blood glucose level in the lipoic acid group was significantly lower than that in the exogenous insulin group （P＜0.05）. The proportion of females and the proportion of fasting insulin ≥ 1 000 μU/mL were significantly higher in the lipoic acid group than in the exogenous insulin group （P＜0.05）. CONCLUSIONS Compared with EIAS， lipoic acid-induced IAS usually causes more severe hypoglycemia， and the fasting insulin level is usually higher than 1 000 μU/mL， which is more common in female patients. The participation of clinical pharmacists in the diagnosis and treatment of EIAS can help improve the diagnosis and treatment level of similar rare diseases and ensure the safety of patients’ medication.

【Objective】 To investigate the therapeutic effect of Huaier on acute pancreatitis (AP) and its potential mechanism. 【Methods】 A mouse model of cerulean-induced AP was used to verify the therapeutic effect of Huaier in vivo. HE staining and immunohistochemical staining were used to evaluate the histopathological changes of the pancreas, and transmission electron microscopy was used to observe the pyroptosis morphology of the pancreas. In vitro, 266-6 cell line was used as the experimental carrier to verify the protective effect of Huaier on acinar cells. Electron microscopy and Western blotting were used to evaluate the pyroptosis level of acinar cells, and ROS fluorescence probe was used to detect the oxidative stress state of acinar cells. 【Results】 Huaier significantly alleviated the severity of AP in mice. HE staining of pancreas showed that necrosis and inflammatory cell infiltration were reduced, and the level of serum amylase was decreased. Immunohistochemical staining and Western blotting showed that Huaier effectively inhibited the expressions of pyroptosis-related molecules such as NLRP3 and GSDMD in pancreatic tissue. Electron microscopy showed that Huaier could reduce the pyroptosis level of pancreatic acinar cells under inflammatory state. In addition, the level of ROS in acinar cells was significantly reduced after the intervention of Huaier, and ROS-mediated pyroptosis of acinar cells could be effectively inhibited by Huaier. 【Conclusion】 Huaier can effectively reduce the severity of AP by inhibiting ROS-mediated pyroptosis of acinar cells.

OBJECTIVE To analyze the cost-effectiveness of abemaciclib， palbociclib and ribociclib combined with aromatase inhibitors （AI） in first-line treatment of hormone receptor-positive （HR+） advanced breast cancer from the perspective of Chinese medical system. METHODS The 20-year disease course of the patients was simulated by the partitioned survival model， and the simulation period was determined to be 4 weeks， the model output was the total cost and quality-adjusted life year （QALY）， the cost and effect were discounted at a discount rate of 5%. A network meta-analysis was constructed by systematically searching relevant clinical trials to obtain the efficacy parameters of abemaciclib， palbociclib and ribociclib combined with AI. Survival fitting and extrapolation were performed based on the survival curve of the placebo group in MONALEESA-2 trial. Cost-effectiveness was assessed by incremental cost-effectiveness ratio （ICER） and incremental net monetary benefit （INMB）， with a willingness-to-pay threshold of 3 times China’s per capita gross domestic product （GDP） in 2023； one-way sensitivity analysis and probability sensitivity analysis were used to detect the influence of parameters on the results and the robustness of the incremental analysis results. RESULTS In the 20-year simulation， compared with palbociclib+AI scheme， the ICER of ribociclib+AI scheme was 58 558.38 yuan/QALY and the INMB was 62 988.20 yuan. Compared with ribociclib+AI scheme， the ICER of abemaciclib+AI scheme was 264 928.34 yuan/QALY and the INMB was 344.84 yuan. One-way sensitivity analysis showed that the incremental analysis results of abemaciclib+AI scheme compared to ribociclib+AI scheme were not robust. Probabilistic sensitivity analysis confirmed that the probability of ribociclib+AI scheme becoming the most economical was the highest when the threshold was 1-3 times China’s per capita GDP in 2023. CONCLUSIONS Ribociclib+AI scheme is more likely to be the most economical first-line treatment than abemaciclib+AI scheme and palbociclib+AI scheme in Chinese patients with HR+ advanced breast cancer when threshold is 1-3 times China’s per capita GDP in 2023.

Objective:To explore the clinical phenotype and genetic characteristics of a Chinese pedigree affected with Spastic paraplegia type 5A (SPG5A).Methods:A pedigree suspected for Hereditary spastic paraplegia (HSP) at Henan Children′s Hospital on August 15 2022 was selected as the study subject. Clinical data of the pedigree was collected. Peripheral blood samples were collected from members of the pedigree. Following extraction of genomic DNA, trio-WGS was carried out, and candidate variant was verified by Sanger sequencing.Results:The child, a 1-year-old boy, had presented with microcephaly, hairy face and dorsal side of distal extremities and trunk, intellectual and motor development delay, increased muscle tone of lower limbs, hyperreflexes of bilateral knee tendons, and positive pathological signs. His parents and sister both had normal phenotypes. Trio-WGS revealed that the child has harbored a homozygous c. 1250G>A (p.Arg417His) variant of the CYP7B1 gene, for which his mother was heterozygous, the father and sister were of the wild type. The variant was determined to have originated from maternal uniparental disomy (UPD). The result of Sanger sequencing was in keeping with the that of trio-WGS. SPG5A due to maternal UPD of chromosome 8 was unreported previously. Conclusion:The child was diagnosed with SPG5A, a complex type of HSP, for which the homozygous c. 1250G>A variant of the CYP7B1 gene derived from maternal UPD may be accountable.

Objective:To construct a whole course management and follow-up platform, named Care Plan, for patients undergoing breast reconstruction surgery, and to evaluate its initial clinical applications.Methods:From June 2023 to January 2024, patients who underwent breast reconstruction surgery at Peking Union Medical College Hospital were selected as the study subjects and enrolled in the Care Plan platform for whole course management. The platform comprised five modules: patient education, self-assessment, medical assessment, medical follow-up, and doctor-patient dialogue, each with corresponding sub-modules and specific components. Each patient was assigned to a case manager who provided one-on-one assessment, sent patient education materials, and conducted follow-ups. The preliminary application of the Care Plan platform was evaluated based on the completeness of patient data, patient education material reading status, doctor-patient dialogue topics, and follow-up responses. At 3 months postoperatively, patients were followed up and further divided into patient education group(reading at least an article on patient educational materials) and control group based on their reading status of educational materials. Patients rated their satisfaction with the surgery using a 5-point questionnaire, including five indicators: expected breast reconstruction outcome, expected surgical type, completeness of information acquisition, breast symmetry, and breast softness. Statistical analysis was performed using SPSS 27.0.1 software, with count data expressed as frequencies and (or) percentages, normally distributed measurement data expressed as Mean±SD, intergroup comparisons conducted using t-test, and P<0.05 indicating statistical significance. Results:A total of 147 female patients aged 16 to 63 years with a body mass index of 16.6 to 31.3 kg/m 2 were ultimately included. All 147 patients completed the content of the self-assessment and medical assessment modules, with relatively complete data. Of the 133 patients who received patient education materials sent through the platform, 38 (28.6%) read the materials, with the sub-module on the introduction and choices of the reconstruction surgery (37.3%, 94/252 ) being the most frequently viewed. A total of 24 patients (16.3%, 24/147 ) raised 45 questions using the doctor-patient dialogue module, with the highest proportion related to consultation issues and complications, each accounting for 22.2% (10/45). Twenty-three patients completed the 3-month follow-up, with 12 in the patient education group and 11 in the control group. The patient education group scored higher than the control group in terms of completeness of information acquisition [(4.58±0.51) points vs. (3.91±0.70) points, t=-2.65, P=0.015], while scoring lower in breast symmetry [(3.92±0.79) points vs. (4.63±0.67) points, t=2.33, P=0.030]. There was no significant difference between the two groups in terms of expected breast reconstruction outcome, expected surgical type, and breast softness scores ( P>0.05 for all). Conclusion:The Care Plan platform for whole course management and follow-up of breast reconstruction can assist medical staff in formulating patient-centered management plans, improve patients’ understanding of surgical information, and aid patients in making decisions regarding breast reconstruction methods.

The management of chronic wounds presents significant challenges, characterized by a low rate of healing and substantial impairment of patients’ quality of life, while also exerting a considerable strain on healthcare resources. Wound healing is a multifactorial and dynamic process, necessitating close monitoring of wound changes and timely, appropriate interventions. Smart bandage/dressing, an innovative approach born from interdisciplinary research, offers a new generation of wound care. It enables dynamic quantitative monitoring of wound conditions, facilitates transdermal drug release and physical mode therapeutics, and adjusts interventions in real time based on monitoring outcomes.
