To guide clinical blood transfusion practices in pediatric patients, the National Health Commission has issued the health standard "Guideline for pediatric transfusion" (WS/T 795-2022). Children undergoing cardiac surgery are at high risk of bleeding, and the causes of perioperative anemia and coagulation disorders in neonates and children are complex and varied, often necessitating the transfusion of allogeneic blood components. This guideline provides direction and recommendations for specific measures in blood management for children undergoing cardiac surgery before, during, and after surgery. This article interprets the background and evidence for the formulation of the blood transfusion provisions for children undergoing cardiac surgery, hoping to facilitate the understanding and implementation of this guideline.

Objective: To evaluate the therapeutic potential and underlying mechanisms of action of propolis in db/db mice. Methods: The chemical composition of propolis was analyzed using UHPLC-MS/MS. Thirty mice, including six wt/wt and 24 db/db mice, were randomly assigned to four groups (n = 6 per group): control, model, metformin (250 mg/kg), low dose propolis (100 mg/kg), and high dose propolis (HDP; 400 mg/kg). Treatments were administered orally for four weeks. Body weight and FBG levels were recorded weekly, and an oral glucose tolerance test was conducted on the 25th day. Serum levels of FIN, GSP, connecting peptide, AST, ALT, HDL, LDL, TG, and TC were quantified using ELISA. Liver histopathology was assessed using H&E and PAS staining. Western blotting was performed to examine the expression levels of NF-κB, phosphorylated NF-κB, IκBα, pIκBα, and AKT in liver tissues. Results: The top 10 metabolites of propolis were identified in positive and negative ion modes. The HDP group exhibited a significant reduction in FBG levels, body weight, connecting peptide levels, homeostatic model assessment of β-cell function scores, and homeostasis model assessment of insulin resistance scores (all P < .05). GSP levels were significantly reduced in both treatment groups (all P < .001). The HDP group also exhibited a reduction in TC and LDL levels (both P < .05), whereas HDL levels increased in both treatment groups (all P < .05). Liver weight, AST levels, and ALT levels were reduced in both treatment groups (all P < .05). Histological analysis revealed improved liver morphology. Protein analysis demonstrated downregulation of phosphorylated NF-κB and phosphorylated IκB, alongside upregulation of AKT. Conclusion Propolis exhibited significant antihyperglycemic effects in db/db mice, potentially by modulating the AKT and NF-κB signaling pathways, highlighting its potential as a therapeutic agent for diabetes management.

This study explored the mechanism of Xiangsha Liujunzi Decoction(XSLJZD) in the treatment of functional dyspepsia(FD) based on inositol-requiring enzyme 1(IRE1)/apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase(JNK) pathway-mediated autophagy in interstitial cells of Cajal(ICC). Forty-eight SPF-grade male SD suckling rats were randomly divided into a blank group and a modeling group, and the integrated modeling method(iodoacetamide gavage + disturbance of hunger and satiety + swimming exhaustion) was used to replicate the FD rat model. After the model replications were successfully completed, the rats were divided into a model group, high-dose, medium-dose, and low-dose groups of XSLJZD(12, 6, and 3 g·kg~(-1)·d~(-1)), and a positive drug group(mosapride of 1.35 mg·kg~(-1)·d~(-1)), and the intervention lasted for 14 days. The gastric emptying rate and intestinal propulsion rate of rats in each group were measured. The histopathological changes in the gastric sinus tissue of rats in each group were observed by hematoxylin-eosin(HE) staining. The ultrastructure of ICC was observed by transmission electron microscopy. The immunofluorescence double staining technique was used to detect the protein expression of phospho-IRE1(p-IRE1), TNF receptor associated factors 2(TRAF2), phospho-ASK1(p-ASK1), phospho-JNK(p-JNK), p62, and Beclin1 in ICC of gastric sinus tissue of rats in each group. Western blot was used to detect the related protein expression of gastric sinus tissue of rats in each group. Compared with those in the blank group, the rats in the model group showed decreased body weight, gastric emptying rate, and intestinal propulsion rate, and transmission electron microscopy revealed damage to the endoplasmic reticulum structure and increased autophagosomes in ICC. Immunofluorescence staining revealed that the ICC of gastric sinus tissue showed a significant elevation of p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins and a significant reduction of p62 protein. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. Compared with the model group, the body weight of rats in the high-dose and medium-dose groups of XSLJZD was increased, and the gastric emptying rate and intestinal propulsion rate were increased. Transmission electron microscopy observed amelioration of structural damage to the endoplasmic reticulum of ICC and reduction of autophagosomes, and the p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins in the ICC of gastric sinus tissue were significantly decreased. The p62 protein was significantly increased. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. XSLJZD can effectively treat FD, and its specific mechanism may be related to the inhibition of the expression of molecules related to the endoplasmic reticulum stress IRE1/ASK1/JNK pathway in ICC and the improvement of autophagy to promote gastric motility in ICC.

The Golgi apparatus(GA),an essential membrane organelle in eukaryotes positioned between the endoplasmic reticulum and the plasma membrane,is responsible for transporting and modifying proteins and lipids generated by the endoplasmic reticulum.The homeostasis of the endoplasmic reticulum and GA plays a crucial role in regulating cellular life.When GA is unable to bear the load of protein or lipid processing and transportation,it enters a state of stress.Cells sense this and activate Golgi-related quality control mechanisms.By regulating the structure and function of GA,it provides important protection for the cell or induces programmed cell death,known as the GA stress response.Understanding the mechanisms and outcomes of cellular GA stress is of great significance for exploring Golgi dynamics and its impact on human diseases.This review summarizes the structure and function of GA under physiological conditions,the phenomenon of GA stress under pathological conditions,and the role of GA in infectious diseases,aiming to provide a basis for the clinical study of new strategies for the prevention and treatment of infectious diseases.

Objective To explore the role of ring finger protein 41(RNF41)in the initiation and progression of cholangiocarcinoma.Methods The expression levels of RNF41 mRNA and protein in tumor tissues and adjacent normal tissues from 84 CHOL patients who underwent total surgical resection at the Second Affiliated Hospital of Kunming Medical University and Kunming Ganmei Hospital between January 2010 and December 2016 were analyzed using bioinformatics,Western blot,and immunohistochemistry.The TIMER 2.0 database was used to analyze the impact of RNF41 on the prognosis and survival of CHOL patients and the relationship between RNF41 and tumor clinical characteristics.RNF41 siRNA was transfected into HCC9810,RBE,and HUCCT1 cells.CCK-8,Edu,colony formation,and Western blot assays were conducted to evaluate the changes in proliferation of cholangiocarcinoma cells between the RNF41 knockdown group and the control group.Transwell assays and detection of EMT and migration markers were performed to assess changes in the invasion ability of cholangiocarcinoma cells between the RNF41 knockdown and control groups.Western blot was used to examine the effect of RNF41 knockdown on epithelial-mesenchymal transition in cholangiocarcinoma cells.Twelve BALB/c mice were randomly divided into two groups:a control group and an RNF41 knockdown group,with six mice in each group.Tumor formation assays,Western blot assays,and immunohistochemistry staining were carried out to investigate the effect of RNF41 knockdown on tumor growth in nude mice.Results Real-time quantitative fluorescence PCR analysis revealed that the expression level of RNF41 mRNA in cholangiocarcinoma tissues was significantly higher than that in the corresponding adjacent non-tumor tissues(P<0.01),and this trend was corroborated at the protein level by immunohistochemical staining.Using the TIMER 2.0 database,we further analyzed the correlation between RNF41 expression and clinicopathological features,including histological grade,tumor stage,lymph node metastasis,and patient survival.The results indicated that elevated RNF41 expression was significantly associated with advanced histological grade and lymph node metastasis in cholangiocarcinoma(P<0.01).Survival analysis demonstrated that high RNF41 expression was closely linked to poor prognosis in patients with cholangiocarcinoma(CHOL).Functional assays,including CCK-8,EdU incorporation,and colony formation,showed that RNF41 knockdown significantly inhibited the proliferation of cholangiocarcinoma cells compared with the control group.Western blot analysis revealed that,following RNF41 silencing,the expression of the epithelial-mesenchymal transition(EMT)marker E-cadherin was markedly upregulated,whereas the levels of mesenchymal markers N-cadherin and MMP9 were significantly reduced(P<0.05).These findings were consistent with the results obtained from in vitro experiments(P<0.01).Moreover,in vivo studies showed that RNF41 knockdown suppressed subcutaneous tumor formation in nude mice(P<0.05).Conclusion RNF41 plays a critical role in promoting the occurrence and progression of cholangiocarcinoma and is closely associated with adverse clinicopathological features and poor prognosis in patients.The knockdown of RNF41 effectively suppresses the proliferation,invasion,epithelial-mesenchymal transition(EMT),and tumorigenicity of cholangiocarcinoma cells.

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.

Dengue fever(DF)is a natural zoonotic disease caused by dengue virus infection which is mainly transmitted by the bite of Aedes mosquito and is endemic in tropical and subtropical regions.At present,DF is spreading rapidly worldwide.Although local transmission caused by imported cases is still the main feature of dengue epidemic in China,its incidence is rap-idly increasing,and the scope of impact is gradually expanding,seriously endangering the health of people.However,no spe-cific antiviral drugs or ideal vaccines are currently available.The experts and scholars from the Chinese Society of Tropical Dis-ease and Parasitology,the Society for Vector Biology and Control of the Chinese Preventive Medicine Association and the Basic Research Committee,China Association for Vaccines formed this consensus on the basis of combing the latest advances in the disease burden of globe and China,traditional vector control and new prevention and control methods,aiming to provide a sci-entific basis for relevant departments to better formulate dengue prevention and control policies.
