This article discusses the important role and practical experience of Guangxi Zhuang Autonomous Region as a bridgehead between China and the Association of Southeast Asian Nations (ASEAN) in the joint prevention and control of cross-border infectious diseases between China and Vietnam. The cross-border transmission of infectious diseases has been effectively managed in Guangxi Zhuang Autonomous Region through a package of strategies, including government leadership, construction of the joint prevention and control mechanism, establishment of dialogue platforms, collaboration of scientific researches, and personnel exchange and training; however, there are still challenges. Further deepening of collaboration is required to meet future needs for infectious disease prevention and control.

To satisfy the growing healthcare demands of the public, it is essential to develop a public service platform for vaccination. This initiative aligns with national policies, optimizes resource allocation, innovates service models, enhances service efficiency, and reduces service costs. Drawing on relevant national policies and regulatory requirements, as well as the notable achievements and practical experiences gained through the exploration and innovation of vaccination service models across various regions, this paper proposes expert recommendations. It defines the essential components and functional specifications for public service platforms, focusing on public needs such as electronic vaccination record management, appointment management, the promotion of electronic vaccination certificates, vaccination certificate verification for school enrollment, vaccination site navigation, and science communication and public engagement. The recommendations aim to serve as a reference for the development of vaccination public service platforms nationwide.

Objective To observe the effect of Qing-Xin-Jie-Yu granule(QXJYG)on the formation of thrombosis in the rat model of arteriovenous bypass thrombosis and the adenosine diphosphate(ADP)-induced platelet aggregation.Methods Thirty-six male SD rats were randomly divided into normal control group,model group,clopidogrel positive control group,QXJYG low-dose,medium-dose and high-dose groups,with 6 rats in each group.The dose of clopidogrel positive control group was 6.74 mg/(kg?d),the dosages of QXJYG in low,medium and high groups were 0.99,1.98,3.96 g/(kg?d),respectively,normal control group and model group were given equal volume of distilled water,and continuous prophylactic intragastric administration for 14 days,once a day.One hour after the final administration,the rats were anesthetized,and the arteriovenous bypass thrombosis model was established by using a polyethylene tube as the arteriovenous bypass bridge(except control group).The thrombus was extracted after 15 min and its weight was weighed by 1/10,000th precision electronic balance.The levels of thromboxane B2(TXB2)and 6-keto-prostaglandin F1α(6-keto-PGF1α)in plasma were determined by ELISA kits.The rate of platelet aggregation induced by ADP in each group was measured using a microplate reader by turbidimetric method.Results Compared with the control group,the weight of arteriovenous bypass thrombus was significantly higher,the level of TXB2 in plasma was significantly higher,while the level of 6-keto-PGF1α was significantly lower,and platelet aggregation was significantly higher after ADP induction in the model group(P＜0.05).Compared with the model group,the weight of arteriovenous bypass thrombosis in clopidogrel positive control group and QXJYG dose groups was significantly decreased(P＜0.05);the inhibition rate of thrombosis formation was 53.80％,23.96％,33.63％,and 32.59％,respectively.The content of TXB2 in plasma was significantly decreased,the content of 6-keto-PGF1α was significantly increased;additionally,the platelet aggregation rate induced by ADP was reduced in clopidogrel positive control group and QXJYG group.Meanwhile,there was a dose-dependence between different doses in QXJYY group(P＜0.05),and the inhibition rate of platelet aggregation was 86.90％,26.17％,38.87％,54.48％,respectively.Conclusion QXJYG can prevent thrombosis formation in the rat model of arteriovenous bypass thrombosis and inhibit platelet aggregation induced by ADP.

ObjectiveTo observe the effects of Qingxin Jieyu granules （QXJYG） on FeCl₃-induced carotid artery thrombosis in rats and on the expression of thrombosis-related proteins tissue factor （TF） and tissue factor pathway inhibitor （TFPI） as well as the protein kinase B （Akt）/nuclear factor-κB （NF-κB） signaling pathway in EA.hy926 cells exposed to tumor necrosis factor-α （TNF-α）， thus preliminarily exploring the mechanism of QXJYG in inhibiting thrombosis. MethodsThirty-six SD rats were randomized into normal control， model， positive control （aspirin， 9 mg·kg^-1）， and low-， medium-， and high-dose （0.99， 1.98， 3.96 g·kg^-1， respectively） QXJYG groups （n=6）. The rats in the drug treatment groups were administrated with corresponding drugs， and those in the normal control group and model group were given an equal volume of distilled water. After 14 consecutive days of prophylactic gavage， the rat model of common carotid artery thrombosis was established with 45% FeCl₃ solution， and the blood vessels were collected and the wet weight of thrombus was weighed by an electronic balance （precision of 1/10 000）. The thrombosis in the common carotid artery of each group of rats was observed by hematoxylin-eosin staining. The plasma levels of von Willebrand factor （vWF）， platelet endothelial cell adhesion molecule-1 （PECAM-1）， tissue-type plasminogen activator （t-PA）， and plasminogen activator inhibitor-1 （PAI-1） were determined by enzyme-linked immunosorbent assay. An endothelial cell injury model was established by treating EA.hy926 human umbilical vein endothelial cells with TNF-α. The cell counting kit-8 method was used to screen the intervention concentrations of QXJYG. Western blot was employed to determine the protein levels of TF， TFPI， Akt， p-Akt， NF-κB p65， and p-NF-κB p65 in each group of cells. ResultsThe animal experiment showed that compared with the normal control group， the model group showed an increase in carotid artery thrombus weight （P<0.05）， with unclear vascular structure and extensive thrombosis in the lumen. In addition， the plasma levels of vWF， PECAM-1， and PAI-1 were elevated， while the t-PA level became lowered （P<0.05） in the model group. Compared with the model group， the aspirin and QXJYG groups showed reductions in the weight of FeCl₃-induced carotid artery thrombi （P<0.05） and thrombosis in the lumen， declines in plasma levels of PECAM-1 and PAI-1， and an elevation in the t-PA level （P<0.05）. Moreover， the QXJYG groups showed reductions in the plasma level of vWF （P<0.05）， which， however， had no significant difference between the aspirin group and the model group. The cell experiments indicated that 31.25， 62.5， 125， 250， 500 mg·L^-1 QXJYG had no effect on the viability of EA.hy926 cells. Therefore， 250， 500 mg·L^-1 QXJYG were selected as the intervention concentrations for subsequent experiments. Western blotting results showed that compared with the control group， the TNF-α stimulation downregulated the expression of TFPI （P<0.05）， upregulated the expression of TF， and increased the ratios of p-Akt/Akt and p-NF-κB p65/NF-κB p65 （P<0.05） in EA.hy926 cells. Compared with the model group， the intervention with QXJYG upregulated the expression of TFPI （P<0.05）， inhibited the expression of TF， and decreased the ratios of p-Akt/Akt and p-NF-κB p65/NF-κB p65 （P<0.05）. ConclusionQXJYG has the effect of inhibiting thrombosis and regulating the expression of TF and TFPI in endothelial cells exposed to TNF-α by suppressing the abnormal activation of the Akt/NF-κB signaling pathway.

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.

Objective:To analyze the clinical features, prognosis and risk factors of SARS-CoV-2 associated acute pancreatitis (SAAP), and provide a basis for early prevention and treatment of SAAP.Methods:Patients with coronavirus disease 19 infection (COVID-19) admitted to Zhejiang Provincial People's Hospital from December 1, 2022 to January 31, 2023 were retrospectively analyzed. Clinical characteristics such as age, gender and other data were recorded, and the indexes of blood routine, liver and kidney function, inflammatory factor, coagulation function, blood gas analysis, immunoglobulin and complement were collected after admission. Patients were divided into pancreatic injury group and non-pancreatic injury group according to the level of serum amylase/lipase. The difference of prognosis and related hematological parameters between the two groups was compared. Multifactorial logistic regression equation was constructed to analyze the risk factors of SAAP.Results:A total of 2 101 patients with COVID-19 who met the criteria were included, including 298 patients in the pancreatic injury group and 1 803 patients in the non-pancreatic injury group. 17 cases (5.7%) in the pancreatic injury group met the diagnostic criteria for AP. The age, male percentage and mortality rate of the pancreatic injury group were all significantly higher than those of the non-pancreatic injury group (all P<0.05). In the pancreatic injury group, white blood cell count, neutrophil-to-lymphocyte ratio, C-reactive protein (CRP), calcitoninogen, erythrocyte sedimentation rate, inflammatory cytokines, tumour necrosis factor, liver and kidney functions, coagulation (D-dimer and plasma fibrinogen degradation products), and lactate level were significantly higher than those in the non-pancreatic injury group (all P<0.05). Serum complement C3, albumin, albumin globule ratio and arterial oxygenation index were lower in the pancreatic injury group (all P<0.05). Multifactorial logistic regression analysis showed that gender, age, CRP, calcitoninogen, total bilirubin, creatinine, PaO 2, PaO 2/FiO 2 and lactate were independent risk factors for the occurrence of pancreatic injury in patients with COVID-19 (all P<0.05). Conclusions:Inflammation-related markers, D-dimer and fibrinogen degradation products were significantly higher in COVID-19 patients comorbid with pancreatic injury than in the patients without pancreatic injury. The risk of SAAP was significantly higher in male patients of senior age. Sex, age, CRP, calcitoninogen, total bilirubin, creatinine, oxygenation index, and lactic acid were independent risk factors for the onset of pancreatic injury in COVID-19 patients.

Objective To elucidate the therapeutic mechanism of Qingxin Jieyu Granule(QXJYG)against atherosclerosis(AS)based on network pharmacology.Methods The major targets and pathways of QXJYG against AS were analyzed using network pharmacology.Rat models of AS established by high-fat feeding combined with intraperitoneal vitamin D3 injection were treated daily with normal saline,atorvastatin(13.15 mg/kg),or QXJYG at 0.99,1.98,and 3.96 g/kg for 8 weeks(n=6).Ultrasound and HE staining were used to assess the function and pathologies of the abdominal aorta.Blood lipids and serum levels of Ang II,ET-1,TXA2,PGI2,and ox-LDL of the rats were detected using an automatic biochemical analyzer or ELISA.The expressions of LOX-1,PPARγ,RXRα,p-P65,VCAM-1 and ICAM-1 in the abdominal aorta were detected with immunohistochemistry.Results The rat models of AS showed obvious abdominal aorta wall thickening,increased pulse wave velocity and pulse index,decreased inner diameter of the abdominal aorta,elevated levels of TC,LDL-C,Ang II,ET-1 and TXA2,and lowered levels of HDL-C and PGI2.QXJYG and atorvastatin treatment of the rat models significantly alleviated histopathological changes of the abdominal aorta,decreased serum levels of TC,LDL-C,Ang II,ET-1 and TXA2,and increased the levels of HDL-C and PGI2.Network pharmacology study suggested the therapeutic effect of QXJYG against AS was mediated by regulating lipid metabolism,PPAR and NF-κB pathways.Consistently,treatments with QXJYG were found to significantly decrease ox-LDL level and LOX-1,P-P65,VCAM-1 and ICAM-1 protein expressions while increasing PPARγ and RXRα expressions in the aorta of AS rats.Conclusion QXJYG alleviates lipid metabolism disorder and improves histopathological changes of the abdominal aorta of AS rats possibly by lowering ox-LDL level,reducing LOX-1 expression,activating PPARγ and RXRα,and inhibiting P65 phosphorylation to reduce VCAM-1 and ICAM-1 expression in the aorta.
