With the acceleration of industrialization,the issue of heavy metal pollution has become increasingly severe,and the potential threat to the ecological environment and human health is increasing.It is necessary and important to detect the contents and species of heavy metal ions.To reduce the influence of complex sample matrices and enrich low contents of analytes,suitable sample pretreatment is usually required before analysis.In recent years,magnetic solid phase extraction(MSPE)based on magnetic extraction materials prepared by rational design and functional modification have attracted much attention in the analysis of heavy metal ions due to their high selectivity,satisfactory adsorption capacity and efficient separation ability.In this paper,the application progress of magnetic composite materials based on ion imprinted polymers,chitosan,metal organic frameworks,ionic liquids and other polymers in the extraction of heavy metal ions from environmental water samples,seafood,radioactive waste and food in recent years was reviewed.The current review focused on the preparation of representative materials in the same category and their adsorption performance towards heavy metal ions.The challenges were analyzed and the future development trend was also prospected.

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.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

OBJECTIVE: To explore the short-term efficacy and adverse reactions of orelabrutinib combined with high-dose methotrexate (HD-MTX) in the first-line treatment of elderly high-risk primary central nervous system lymphoma (PCNSL), as well as the survival of patients. METHODS: Twenty-five elderly patients with high-risk primary central nervous system diffuse large B-cell lymphoma admitted to Fujian Provincial Hospital from June 2016 to June 2022 were enrolled in this study, and complete clinical data from all patients were collected retrospectively, and the cut-off for follow-up was December 2022. 15 patients had received temmozolomide combined with HD-MTX regimen for at least four cycles, sequential lenalidomide maintenance therapy, while 10 patients had received orelabrutinib combined with HD-MTX regimen for at least four cycles, sequential orelabrutinib maintenance therapy. The short-term efficacy and adverse reactions of the two groups of patients after treatment were observed. Kaplan-Meier was used to analyze the progression-free survival (PFS) and time to progression (TTP). RESULTS: The objective response rate (ORR) and 2-year median FPS of orelabrutinib combined with HD-MTX regimen group were similar to the temozolomide combined with HD-MTX regimen group (ORR: 100% vs 66.7%; 2-year median PFS: 16 months vs 15 months, P>0.05). The 2-year median TTP of the orelabrutinib+HD-MTX regimen group was better than that of the temozolomide+HD-MTX regimen group (not reached vs 12 months, P<0.05). There were no significant differences in adverse reactions such as gastrointestinal reactions, bone marrow suppression, liver and kidney damage, cardiotoxicity, pneumonia and bleeding between these two groups (P>0.05). CONCLUSION For elderly patients with high-risk PCNSL, orelabrutinib combined with HD-MTX has reliable short-term efficacy, good safety, and tolerable adverse reactions, which is worthy of clinical promotion.

Objective:To systematically review the domestic and foreign cognitive assessment instruments for neonatal pain management, with a view to providing reference for future research.Methods:The research on the development of the cognitive assessment instrument for neonatal pain management was searched through computers on China National Knowledge Infrastructure (CNKI), WanFang Data, China Biomedical Literature Database, VIP, Web of Science Core Collection, PubMed and Embase. The search period was from database establishment to August 30, 2022. We summarized and analyzed the article that met the inclusion criteria.Results:A total of 8 cognitive assessment instruments were extracted. The most frequent content of the tools was the cognition and implementation of analgesic drugs, non-drug nursing measures and pain intensity assessment, as well as education and training, parent involvement and other contents.Conclusions:There is a significant gap between domestic research and foreign research on neonatal pain. Most of the cognitive assessment instruments for neonatal pain management are translated from foreign versions into Chinese. It is necessary to develop a neonatal pain management cognitive assessment instrument suitable for Chinese medical culture background on the basis of comprehensive understanding of relevant assessment instruments at home and abroad, and in combination with the latest guidelines on neonatal pain management, so as to improve the awareness and quality of medical and nursing staff on neonatal pain management.

OBJECTIVE: To overview the methodological quality, report quality and evidence quality of the systematic review (SR) of acupuncture for vascular cognitive impairment ( VCI ). METHODS: The SRs regarding acupuncture for VCI were searched in PubMed, Cochrane Library, EMbase, CNKI, SinoMed, Wanfang and VIP databases. The retrieval period was from the establishment of the database to September 24, 2020. The report quality, methodological quality and evidence quality of the included SRs were evaluated by PRISMA statement, the AMSTAR 2 tool and the GRADE system. RESULTS: A total of 22 SRs were included, including 102 outcome indexes. The methodological quality was generally low, with low scores on items 2, 5, 7, 10, 14, 15 and 16. The report quality was good, with scores ranging from 19 points to 24.5 points. The problems of report quality were mainly reflected in the aspects of structural abstract, program and registration, other analysis and funding sources. The level of outcome indexes of SRs was mostly low or very low, and the main leading factor was limitation, followed by inconsistency and inaccuracy. CONCLUSION Acupuncture for VCI is supported by low quality evidence of evidence-based medicine, but the methodological quality and evidence body quality of relevant SRs are poor, and the standardization is needed to be improved.

The existing problems in the outcomes of randomized controlled trials (RCTs) of acupuncture for vascular cognitive impairment (VCI) during recent five years are analyzed and suggestions are proposed. The RCTs of acupuncture for VCI were selected in PubMed, EMbase, Cochrane Library, Clinical Trials, CNKI database, Wanfang database, VIP database, SinoMed database and Chinese Clinical Trial Registry (ChiCTR) from January 1, 2015 to September 14, 2020. The outcomes were extracted and analyzed. As a result, 21 RCTs were included and the outcomes used were divided into 9 categories: clinical symptom/sign indexes, quality of life indexes, neuroimaging indexes, neuroelectrophysiology indexes, blood biochemical indexes, hemorheology indexes, TCM syndrome score indexes, clinical efficacy indexes, and safety indexes. Among them, the top three of the most used outcomes were clinical symptoms/signs indexes (21, 100.0%), clinical efficacy indexes (14, 66.7%) and quality of life indexes (12, 57.1%). In the RCTs of acupuncture for VCI, attention should be paid to distinguish the primary outcomes and secondary outcomes, adopt objective and standardized efficacy evaluation, and give consideration to report the outcomes of safety, health economic and TCM characteristic indexes.

Acupoint autohemotherapy at bilateral Zusanli (ST36) and Xuehai (SP10) was used to treat a 26-year-old female patient who had suffered from recalcitrant atopic eczema (AE) for five years. The treatment was applied at a frequency of once per week for the first month, followed by a three-month period of once every other week. At the end of treatment, the patient's AE symptoms were entirely resolved, and by the end of a six-month follow-up her immunoglobulin E level had returned to the normal range. Further, there was no relapse of AE symptoms during the six-month follow-up. Therefore, we hypothesized that after the repeated treatments the local inflammatory reaction induced by autologous blood injection triggered a local immune response, followed by a systemic immune response after the repeated treatment, finally leading to the anti-inflammation and immunomodulation effects. This case suggests that acupoint autohemotherapy could be used as an effective complementary treatment for recalcitrant AE, especially in cases where other treatments have failed. Further comparative studies are needed to corroborate the value and mechanisms of this therapy.

OBJECTIVE: To analyze clinical response of the Rituximab-based chemotherapy and prognostic features in patients with primary gastric diffuse large B-cell lymphoma (PGDLBCL). METHODS: From June 2008 to December 2020, the data of 53 PGDLBCL patients were analyzed retrospectively. RESULTS: The median age was 46(25-77) years old in 53 patients including 35 males and 18 females. Stomachache is the most common symptom. The diagnosis were confirmed in 47 patients by endoscopic biopsy and 6 patients by surgery. Twenty-six patients had Ⅰ/Ⅱ1 stage (Lugano staging system) disease and 27 cases had II2/IV stage disease. All patients were treated with chemotherapy, including RCHOP (25/53) and R-DA-EPOCH (28/53). Complete remission rate was 79.2%（42/53）. The 3-year and 5-year overall survival (OS) rates were 77.4% and 69.8%. Univariate analysis showed that lactate dehydrogenase(LDH), Lugano stage and lesion size affected OS. Multivariate Cox regression analysis revealed that IPI score and Lugano stage were independent prognosis risk factors affecting OS. The patients in the R-DA-EPOCH group presented better survival outcomes than those in the RCHOP group with late stage (P_5-year OS=0.035). CONCLUSION Rituximab in combination with chemotherapy is the backbone of therapy for PGDLBCL. IPI score and Lugano stage are independent prognosis risk factors affecting OS of PGDLBCL. R-DA-EPOCH can be superior to R-CHOP as a first-line regimen in PGDLBCL patients with late stage.
