To guide transfusion practice in critically ill children who often need plasma and platelet transfusions, the Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding (TAXI-CAB) developed Recommendations and Expert Consensus for Plasma and Platelet Transfusion Practice in Critically Ill Children. This guideline addresses 53 recommendations related to plasma and platelet transfusion in critically ill children with 8 kinds of diseases, laboratory testing, selection/treatment of plasma and platelet components, and research priorities. This paper introduces the specific methods and results of the recommendation formation of the guideline.

Type 2 diabetes mellitus(T2DM) is a prevalent metabolic and endocrine disorder. Long-term hyperglycemia can lead to severe chronic complications, imposing substantial economic burdens on both society and patients. Despite the availability of various hypoglycemic agents for clinical use, these agents often fail to meet the therapeutic needs of T2DM and its complications. Consequently, there is an urgent need for novel therapeutic strategies and drugs. Lithocarpus litseifolius(L. litseifolius), commonly referred to as "cordyceps on trees", has a long history of use in traditional medicine and can be applied in tea, sugar, and medicine. Research indicates that L. litseifolius extracts are rich in dihydrochalcones, including trilobatin, phloridzin, and phloretin, which exhibit a range of pharmacological activities, such as anti-inflammatory, antioxidant, hypoglycemic, hypolipidemic, hepatoprotective, and cardioprotective effects. These properties suggest potential applications in the treatment of T2DM and its complications. This review systematically compiled and organized the relevant literature from the past decade on dihydrochalcones(trilobatin, phloridzin, and phloretin) from L. litseifolius extracts. It highlighted recent research progress regarding their role in treating T2DM and its complications through mechanisms such as reducing insulin resistance, regulating glucose transport, improving glucose and lipid metabolism, modulating enzyme activity, regulating gut microbiota, and alleviating inflammation and oxidative damage. The purpose of this review is to provide a reference and basis for future research on the prevention and treatment of T2DM and its complications using dihydrochalcones(trilobatin, phloridzin, and phloretin) from L. litseifolius extracts.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Based on systematic review and consensus meetings of international multidisciplinary experts, the Transfusion and Anemia Expert Initiative—Control/Avoidance of Bleeding (TAXI-CAB) project team developed management strategies for platelet and plasma transfusion in critically ill children. This consensus presents five expert consensus statements and two recommendations addressing two key questions: 1) What Laboratory Tests and Physiologic Triggers Should Guide the Decision to Administer a Platelet or Plasma Transfusion in Critically ill Children? 2) What Product Attributes Are Optimal to Guide Specific Product Selection? This consensus provides guidance for decision-making regarding plasma and platelet transfusion in critically ill children in two aspects: relevant laboratory testing indicators and additional special properties of blood components. This article explains the rationale behind the recommendations in this part of the guideline, aiming to emphasize the need for clinicians to develop transfusion strategies based on multidimensional assessment, while calling for enhanced interdisciplinary collaboration and evidence-based research to optimize blood management in critically ill children, reducing the risk of over-transfusion and improving treatment outcomes. Furthermore, there remains an urgent need for further research to explore laboratory indicators associated with bleeding risk to guide transfusion therapy.

Objective:To evaluate the efficacy and safety of pembrolizumab plus nab-paclitaxel and platinum as first-line treatment in patients with recurrent or metastatic head and neck squamous-cell carcinoma (R/M HNSCC).Methods:This was a prospective, single-arm, open label, phase 2 clinical study enrolling patients at the Cancer Hospital of the Chinese Academy of Medical Sciences with R/M HNSCC treated with pembrolizumab plus nab-paclitaxel and cisplatin or carboplatin. After six cycles of treatment, patients received pembrolizumab as maintenance therapy until disease progression or intolerable toxicity or completion of 35 cycles of treatment. The primary endpoint was objective response rate, and secondary endpoints included overall survival, progression-free survival, and safety profile. Efficacy was evaluated according to the response evaluation criteria in solid tumors 1.1, survival analysis was performed using the Kaplan-Meier method, and adverse events were assessed using the America National Cancer Institute Common Terminology Criteria for Adverse Events 5.0.Results:A total of 30 patients with R/M HNSCC were enrolled from 23 April 2021 to 22 March 2023, including 28 males and 2 females, with a median age of 67 years. The median follow-up time was 14.5 months, the objective response rate was 70.0%, the disease control rate was 96.7%, and the median progression-free survival and overall survival of all patients were 11.6 months and 18.8 months, respectively. Median duration of response was up to 17.3 months. Grade≥3 treatment-related adverse events were leukopenia (26.7%), neutropenia (26.7%), peripheral neurotoxicity (3.3%), rash (3.3%), hyperalgesia (3.3%), and immune-related pneumonitis (3.3%). The most common immune-related adverse event was hypothyroidism (40.0%).Conclusion:Pembrolizumab combined with nab-paclitaxel and platinum shows encouraging antitumor activity accompanied with a manageable safety profile in untreated R/M HNSCC patients in China.

Objective:To investigate the correlation between plasma fibrinogen/serum albumin ratio (FAR) and the degree of cerebral artery stenosis in patients with acute cerebral infarction (ACI).Methods:Clinical data of 189 patients with acute cerebral infarction diagnosed and treated in the Department of Neurology of the First Affiliated Hospital of Hainan Medical College from January 2021 to March 2023 were selected for retrospective analysis. Digital subtraction angiography (DSA) was improved, and they were divided into four groups according to the degree of intracranial vascular stenosis according to NASCET grading method: no stenosis group (47 cases), mild stenosis group (45 cases), moderate stenosis group (39 cases) and severe stenosis and occlusion group (58 cases). The differences of basic data, plasma fibrinogen/serum albumin ratio (FAR) and other inflammatory indicators among all groups were compared, and the correlation between FAR level and the severity of cerebral artery stenosis was analyzed. Multivariate Logistic regression was used to explore the factors influencing to cerebral artery stenosis and ROC curve was used to evaluate the diagnostic value of FAR in the degree of cerebral artery stenosis in cerebral infarction patients.Results:There were significant differences in blood neutrophil (NEU), mean platelet volume (MPV), fibrinogen (FIB), fibrinogen (FIB), albumin (ALB) and FAR among the 4 groups (statistical values were H=11.50, H=8.44, F=5.16, H=30.93, H=40.38; all P<0.05). Correlation analysis showed a positive correlation between FAR and the degree of cerebral artery stenosis ( r=0.455, P<0.05). Multivariate Logistic regression showed that FAR was an independent risk factor for the degree of cerebral artery stenosis ( OR=1.445, 95% CI=1.261-1.655, P<0.001). Conclusion:FAR is an independent risk factor for cerebral artery stenosis in patients with acute cerebral infarction (ACI), and may be a new biomarker for predicting cerebral artery stenosis.

Magnetic particles(MPs)are widely present in the environment,with high prevalence and complex sources.During the past decade,with the rapid development of separation techniques and detection methods for MPs,exogenous MPs have been found to be present in different parts of human body.Especially,the presence of MPs in human brain and blood has led to a high level of concern about their health risks,as the potential association with the development of neurodegenerative diseases such as Alzheimer's disease.Therefore,analysis of MPs in environmental and biological media is an important basis for understanding their physicochemical properties,investigating their biogeochemical cycling processes,and assessing their environmental and health risks.Here,the occurrence of MPs in different environmental media and biological samples were systematically summarized.The separation methods,characterization methods,qualitative and quantitative analysis methods,and source apportionment techniques of MPs were also reviewed.Finally,the future challenges in the development of analytical techniques for MPs were discussed.

Aim To study the permeability of salidro-side(Sal)to the blood brain barrier(BBB)by high-performance liquid chromatography electrospray ioniza-tion tandem mass spectrometry(UPLC-ESI-MS-MS),and to explore the target and mechanism of Sal in the treatment of ischemic stroke(IS)by network pharma-cology,molecular docking technique and animal exper-iment.Methods UPLC-ESI-MS/MS was used to study the BBB penetration of Sal.Multiple databases were used to predict the target of Sal and the disease target of IS,GO and KEGG enrichment analysis were performed and verified by molecular docking technique and animal experiments.Results After Sal adminis-tration to normal rats and MCAO rats,Sal prototype and the metabolite tyrosol were detected in plasma and brain tissue of rats.A total of 191 targets were identi-fied by network pharmacology,the enrichment analysis of GO mainly involved in the biological processes of proteolysis and positive regulation of cell migration,and the analysis of KEGG pathway suggested that PI3K-Akt,MAPK,FOXO and other signaling path-ways played a key role in the treatment of IS by Sal The results of molecular docking showed that Sal had good binding ability with the core target of docking,and the results of animal experiments showed that Sal could significantly improve the neurologic impairment of MCAO rats,the number of Nissl-positive cells in is-chemic side significantly increased,and the expression of VEGF,EGFR and IGF1 increased,while the ex-pression of IL-6 and MMP9 was inhibited.Conclu-sions Sal is able to penetrate the BBB and enter the central nervous system for its pharmacological effects.Network pharmacology predicts the core targets of Sal in the treatment of IS,including VEGFA,EGFR,IL-6,MMP9,IGF1,CASP3,ALB,SRC.The effects of Sal on some core targets can be verified by animal ex-periments,to provide a reference for further study of the mechanism of Sal in the treatment of IS.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
