OBJECTIVE To provide references and suggestions for the establishment of medication management in care transitions in China. METHODS This study systematically reviewed the medication management in care transitions led by pharmacists in the United States， summarized the clinical practice evidence of its service system， personnel configuration， development bottlenecks and effect benefits， and explored the suggestions for optimizing the work in China. RESULTS & CONCLUSIONS The United States medication management in care transitions is characterized by standardized workflows and precision interventions. It focuses on the treatment continuity period when patients transition across institutions and stages， establishing a pharmacist-led， multidisciplinary collaborative monitoring system. Empirical studies confirm its effectiveness in reducing medication errors， lowering healthcare costs， and improving patient satisfaction. The United States model has achieved professionalization and standardization. Adapting its successful experiences as well as combining our local situation can establish a pharmacist-led medication management framework in care transitions through four key dimensions： role definition， training mechanisms， standardized protocols， and evaluation metrics， and improve the further development of pharmaceutical care services.

Since the first successful transcatheter aortic valve replacement (TAVR) was performed globally in 2002, the TAVR technology has become increasingly mature. With more than a decade of development in China, its application experience, device research and development, procedural improvements, evidence-based medicine, and guideline updates have continuously progressed, leading to a significant increase in the number of procedures conducted. Compared to traditional surgical operations, TAVR has different postoperative monitoring points and principles for the prevention and management of complications, necessitating the formulation of corresponding monitoring and treatment protocols that align with the technical characteristics of the procedure. This guideline is based on clinical practice and incorporates both domestic and international literature as well as the experiences of Fuwai Hospital. It distills and organizes routine postoperative monitoring practices, process optimization, and complication management for TAVR, establishing a set of practical guidelines for postoperative monitoring in China. These guidelines have strong practical value for optimizing postoperative management strategies and preventing and managing complications, which is beneficial for early functional recovery of patients, shortening hospital stays, and reducing complication rates. They provide guidance and reference for domestic peers and support the standardized development and quality improvement of postoperative management for TAVR in China.

INTRODUCTION: In December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus emerged and caused a worldwide pandemic, leading to measures being imposed by many countries to reduce its transmission. Singapore implemented the 'circuit breaker', which restricted all movements except for access to necessities and healthcare services. We aimed to investigate the impact of lockdown measures on the pattern of trauma and its effects. METHODS: An observational, retrospective, single-centre descriptive study was conducted using the trauma registry in Singapore General Hospital. It included patients above 18 years old who presented to the emergency department with trauma and were subsequently admitted. Patients admitted from 1 February 2020 to 31 July 2020 and those admitted during the same timeframe in 2019 were studied. Subgroup analyses were performed for patients aged ≥65 years and those <65 years. RESULTS: A total of 1,037 patients were included for analysis. A 17.6% increase in trauma presentations was seen from 2019 to 2020. Patients aged ≥65 years accounted for the rise in admissions. The predominant mechanism of injury was falls at home for older patients and vehicular accidents in patients <65 years. There were no significant differences in injury severity score, intensive care/high-dependency unit admission rates, length of stay, mortality rate, and subsequent need for inpatient rehabilitation. CONCLUSION Our study provided information on differences in trauma presentations before and during the COVID-19 pandemic. Further studies are required to better inform on additional precautionary measures needed to reduce trauma and improve safety during future lockdowns and pandemics.

By employing the analytic hierarchy process(AHP), the CRITIC method(a weight determination method based on indicator correlations), and the AHP-CRITIC hybrid weighting method, the weight coefficients of evaluation indicators were determined, followed by a comprehensive score comparison. The grey correlation analysis was then performed to analyze the results calculated using the hybrid weighting method. Subsequently, a backpropagation-artificial neural network(BP-ANN) model was constructed to predict the extraction process parameters and optimize the extraction process for Shenxiong Huanglian Jiedu Granules(SHJG). In the extraction process, an L_9(3~4) orthogonal experiment was designed to optimize three factors at three levels, including extraction frequency, water addition amount, and extraction time. The evaluation indicators included geniposide, berberine, ginsenoside Rg_1 + Re, ginsenoside Rb_1, ferulic acid, and extract yield. Finally, the optimal extraction results obtained by the orthogonal experiment, grey correlation analysis, and BP-ANN method were compared, and validation experiments were conducted. The results showed that the optimal extraction process involved two rounds of aqueous extraction, each lasting one hour; the first extraction used ten times the amount of added water, while the second extraction used eight times the amount. In the validation experiments, the average content of each indicator component was higher than the average content obtained in the orthogonal experiment, with a higher comprehensive score. The optimized extraction process parameters were reliable and stable, making them suitable for subsequent preparation process research.

Objective To investigate the mechanisms by which paeoniflorin improves tissue and cell damage caused by diabetic retinopathy(DR)through the hypoxia-induced factor-1α(HIF-1α)pathway.Methods Thirty rats were ran-domly divided into a control group(10 normal rats),a DR group(10 diabetic model rats)and a paeoniflorin group(10 dia-betic model rats given 80 mg·kg-1 paeoniflorin by gavage).Rat retinal microvascular endothelial cells(rRMECs)were di-vided into a control group(cultured with 5 mmol·L-1 glucose),a high glucose group(cultured with 30 mmol·L-1 glu-cose)and a paeoniflorin group(cultured with 30 mmol·L-1 glucose and 20 mol·L-1 paeoniflorin).The three groups of cells were all cultured for 24 h.Fasting blood glucose was measured by a glucose meter.Hematoxylin and eosin(HE)stai-ning was used to detect the retinal histopathological structure.The levels of HIF-1α and vascular endothelial growth factor(VEGF)proteins and mRNAs in retinal tissues and rRMECs were detected by Western blotting and real time quantitative polymerase chain reaction(RT-qPCR).The proliferative ability of rRMECs was detected by the EdU kit.The serum levels of total cholesterol(TC),triglyceride(TG),low density cholesterol(LDL-C),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in retinal tissues and rRMECs were detected by kits.The activity and invasive ability of rRMECs were measured by CCK-8 and Transwell assay,respectively.The levels of HIF-1α and VEGF proteins in rRMECs were detected by immunofluorescence staining.Results Compared with those in the DR group,the fasting blood glucose,TC,TG and LDL-C levels in the paeoniflorin group were significantly decreased(all P＜0.05).The retinal tissue was loose with an un-clear boundary in the DR group,compared with that in the control group.The retinal tissue in the paeoniflorin group was less loose with a clearer boundary than that in the DR group.The levels of HIF-1α and VEGF proteins and mRNAs,TNF-αand IL-6 in retinal tissues of the DR group were significantly higher than those of the control group(all P＜0.05).The lev-els of HIF-1α and VEGF proteins and mRNAs,TNF-α and IL-6 in retinal tissues of the paeoniflorin group were significantly lower than those in the DR group(all P＜0.05).The activity,proliferation and invasive abilities of rRMECs in the high glu-cose group were higher than those in the control group(all P＜0.05).Compared with those in the high glucose group,rRMECs in the paeoniflorin group showed decreased cell activity,proliferation and invasive abilities(all P＜0.05).The lev-els of HIF-1α and VEGF proteins and mRNAs,TNF-α and IL-6 in the rRMECs of the high glucose group were higher than those of the control group(all P＜0.05).The levels of HIF-1α and VEGF proteins and mRNAs,TNF-α and IL-6 in the rRMECs of the paeoniflorin group were lower than those of the high glucose group(all P＜0.05).Conclusion Paeoni-florin can down-regulate the HIF-1α/VEGF pathway to improve the inflammatory injury of the retinal tissue and inhibit rRMEC activity,proliferation and invasive abilities in DR rats,thereby preventing angiogenesis and reducing the incidence of DR.

Objective:This study aims to establish an animal model that accurately replicates the clinical symptoms and pathologi-cal changes of late-stage human TMJOA,with the goal of providing a standardized and reliable animal experimental method for sub-sequent research on the disease.Methods:Forty-eight male New Zealand rabbits aged 4 to 6 months were randomly divided into a model group and a sham group.The animals in the model group underwent bilateral temporomandibular joint disc perforation surgery,while the animals in the sham group underwent a sham surgery.The modeling effects were assessed at 4,8,and 12 weeks post-surgery using nociceptive behavior assessments,passive mouth opening measurements,histological analysis(HE,Safranin O-fast green staining),immunohistochemistry,immunofluorescence staining,and magnetic resonance imaging(MRI).Results:Animals in the model group exhibited distinct TMJOA symptoms,including joint pain and restricted mouth opening.Histologically,typical osteo-arthritis changes were evident.The Mankin osteoarthritis score was significantly higher(P＜O.05).Conclusion:The TMJ disc perfo-ration model resmbled the same clinical manifestations and pathological changes seen in human TMJOA.

Aim To investigate the anti-acute lung injury(ALI)effect of Sterculiae Lychnophorae Semen(SLS)and its mechanism.Methods The main ac-tive components of SLS and their core targets and path-ways of action against ALI were obtained by network pharmacology methods.Subsequently,molecular doc-king technology and in vitro cellular experiments were applied for validation.Results A total of 19 core tar-gets were obtained,including HSP90AA1,CASP3,TNF,MAPK8 and MAPK14.The mechanisms may in-volve signaling pathways such as cancer,PI3K/Akt and MAPK.Molecular docking confirmed that the key targets of SLS formed a better binding activity with the relevant active ingredients.The in vitro results showed that SLS was able to protect the PM2.5-contaminated BEAS-2B cells,inhibit their NO,IL-1β and TNF-αlevels,and reduce the expression of p-p38 MAPK and p-JNK proteins.Conclusions The study successfully predicts the active ingredients,targets and signaling pathways of SLS against ALI,and in vitro experiments demonstrate that SLS might protect BEAS-2B cells from PM2.5 stimulus-induced inflammation and apoptosis by inhibiting the over-activation of p38 MAPK and JNK signaling pathways.
