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 construct a training program for retuming to work after delivery based on Morrison's job adaptation theory in operating room nurses and to explore its application effect.Methods On the basis of literature research and Delphi expert consultation method,a training program of postpartum return of operating room nurses was constructed.From August 2021 to December 2022,the preliminary application of this research program was carried out,with 6 cases in an experimental group and 5 cases in a control group.The differences between the 2 groups were compared by Job Adaptation Scale,Psychological Resilience Scale and satisfaction evaluation,and the application effect was evaluated.Results After 2 rounds of correspondence,a training program for postpartum return of operating room nurses was formed,which included 4 first-level indicators(role adaptation,task adaptation,environment adaptation and cultural adaptation),and 32 second-level indicators.The authority coefficients of the 2 rounds of correspondence consultation were 0.908 and 0.917,and the Kendall W coefficients were 0.224 and 0.206,respectively(both P＜0.001).The preliminary application results showed that there were statistically significant differences in job adaptation and satisfaction evaluation between the 2 groups(both P＜0.05).There was no significant difference in psychological resilience score between groups(P＞0.05).Conclusion The postpartum retum training program for operating room nurses established in this study is scientific and practical to a certain extent.In the future,samples can be expanded and multi-center studies can be carried out to further test the practicability and effectiveness of the program.

ObjectiveTo elucidate the pharmacodynamic substances responsible for the anti-inflammatory and analgesic effects of Cyperi Rhizoma by structure-activity omics. MethodOn the basis of the previous in vitro efficacy study by our research group， this study explored the in vivo efficacy of the flavonoids in Cyperi Rhizoma. The flavonoids in Cyperi Rhizoma and their targets were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， PharmMapper， Swiss TargetPrediction， and available articles. The targets of the anti-inflammatory and analgesic effects were collected from DisGeNET and Online Mendelian Inheritance in Man （OMIM）. The common targets shared by flavonoids and the effects were selected as the direct targets of flavonoids endowing Cyperi Rhizoma with anti-inflammatory and analgesic effects， and protein-protein interaction （PPI） network of the core targets was constructed. The method of structure-activity omics was employed to correlate the structure and efficacy of one or more classes of chemical components in Cyperi Rhizoma with the targets as a bridge. The components were classified according to structure. Molecular docking of components to core targets was carried out via SYBYL-X 2.1.1， PyMol， and Discovery Studio 4.5 visualizer. Two targets with the highest binding affinity were selected to explore the relationship between compound structures and targets. ResultThe flavonoids in Cyperi Rhizoma exerted anti-inflammatory and analgesic effects on the mouse model of pain induced by formaldehyde. Eighteen components and 115 direct targets were screened out， and the core targets with high activities were protein kinase B1 （Akt1）， interleukin-1β （IL-1β）， cellular tumor antigen p53 （TP53）， prostaglandin-endoperoxide synthase 2 （PTGS2）， and matrix metalloproteinase-9 （MMP-9）. According to the structures， the flavonoids in Cyperi Rhizoma were classified into bioflavonoids， flavonols， flavones， and flavanes. The molecular docking results showed that flavonoids of Cyperi Rhizoma had the highest binding affinity to TP53 and PTGS2. The results of structure-activity omics showed that bioflavonoids represented the best binding structure to the targets， while their polyhydroxyl etherification resulted in a significant decrease in the binding affinity to PTGS2. Glycosides had higher binding affinity to PTGS2. The introduction of the long-chain hydrocarbon group to the A ring of flavonols facilitated the binding to TP53， while the change of B ring substituents was not the main factor affecting the binding affinity. The 3，4-dihydroxyl flavane outperformed 3-hydroxyl flavane in the binding to TP53， while the two compounds showed similar binding affinity to PTGS2. ConclusionThe method of structure-activity omics was used to analyze the material basis for the anti-inflammatory and analgesic effects of flavonoids in Cyperi Rhizoma. Structure-activity omics provides new ideas for revealing the pharmacodynamic substances of traditional Chinese medicine.

AIM:To explore the correlation and consistency of three tear assessment methods in the diagnosis of dry eye, which include the Schirmer Ⅰ test(SⅠt), tear meniscus height(TMH)measurement and a new generation of tear detection technology-Strip meniscometry tube(SMTube).METHODS: A diagnostic test study. A total of 183 dry eye outpatients(183 right eyes)in the Dry Eye Center of Henan Eye Hospital were enrolled from May to June 2021. The SⅠt, TMH and SMTube were performed on all patients, and the correlation and consistency of the measurement results were analyzed.RESULTS:The ocular surface disease index(OSDI)of all included patients was 43.75(31.25, 58.33), noninvasive breakup time(NIBUT)was 7.26(4.97, 9.37)s, and the results of SⅠt, TMH and SMTube were 6(2, 12)mm/5min, 0.18(0.14, 0.22)mm and 5(3,8)mm/5s, respectively; The results of correlation analysis: TMH was positively correlated with SMTube(rs=0.751, P<0.001), however, SⅠt had no correlation with TMH(rs=0.139, P=0.060)and SMTube(rs=0.019, P=0.799). The results of consistency analysis: TMH showed good consistency with SMTube(Kappa=0.794, P=0.044), however, SⅠt showed poor consistency with TMH(Kappa=0.271, P=0.074)and SMTube(Kappa=0.193, P=0.070)respectively.CONCLUSION:SMTube is a new, simple and convenient tool for evaluating tear volume. It has a good correlation and consistency with TMH measurement results. Therefore, it can replace TMH measurement, but cannot replace SⅠt in clinical application.

OBJECTIVE: To evaluate the trend of notified incidence of pulmonary tuberculosis (PTB) in China at different periods by population and region and to explore the effect of TB prevention and control in recent years. METHODS: Using pooled data on TB cases reported by the TB Information Management Reporting System (TBIMS) from 2005 to 2020, we calculated the annual percentage change (APC) using the Joinpoint regression model. RESULTS: From 2005 to 2020, a total of 16.2 million cases of PTB were reported in China, with an average notified incidence of 75.5 per 100,000 population. The age standardization rate (ASR) continued to decline from 116.9 (/100,000) in 2005 to 47.6 (/100,000) in 2020, with an average annual decrease of 5.6% [APC = -5.6, 95% confidence interval ( CI): -7.0 to -4.2]. The smallest decline occurred in 2011-2018 (APC = -3.4, 95% CI: -4.6 to -2.3) and the largest decrease in 2018-2020 (APC = -9.2, 95% CI: -16.4 to -1.3). From 2005 to 2020, the ASR in males (159.8 per 100,000 in 2005, 72.0 per 100,000 in 2020) was higher than that in females (62.2 per 100,000 in 2005, 32.3 per 100,000 in 2020), with an average annual decline of 6.0% for male and 4.9% for female. The average notified incidence was the highest among older adults (65 years and over) (182.3/100,000), with an average annual decline of 6.4%; children (0-14 years) were the lowest (4.8/100,000), with an average annual decline of 7.3%, but a significant increase of 3.3% between 2014 and 2020 (APC = 3.3, 95% CI: 1.4 to 5.2); middle-aged (35-64 years) decreased by 5.8%; and youth (15-34 years) decreased by an average annual rate of 4.2%. The average ASR in rural areas (81.3/100,000) is higher than that in urban areas (76.1/100,000). The average annual decline in rural areas was 4.5% and 6.3% in urban areas. South China had the highest average ASR (103.2/100,000), with an average annual decline of 5.9%, while North China had the lowest (56.5/100,000), with an average annual decline of 5.9%. The average ASR in the southwest was 95.3 (/100,000), with the smallest annual decline (APC = -4.5, 95% CI: -5.5 to -3.5); the average ASR in the Northwest China was 100.1 (/100,000), with the largest annual decline (APC = -6.4, 95% CI: -10.0 to -2.7); Central, Northeastern, and Eastern China declined by an average of 5.2%, 6.2%, and 6.1% per year, respectively. CONCLUSIONS From 2005 to 2020, the notified incidence of PTB in China continued to decline, falling by 55%. For high-risk groups such as males, older adults, high-burden areas in South, Southwest, and Northwest China, and rural regions, proactive screening should be strengthened to provide timely and effective anti-TB treatment and patient management services for confirmed cases. There is also a necessity to be vigilant about the upward trend of children in recent years, the specific reasons for which need to be further studied.

Gelsemium elegans is a traditional Chinese herb of medicinal importance, with indole terpene alkaloids as its main active components. To study the expression of the most suitable housekeeping reference genes in G. elegans, the root bark, stem segments, leaves and inflorescences of four different parts of G. elegans were used as materials in this study. The expression stability of 10 candidate housekeeping reference genes (18S, GAPDH, Actin, TUA, TUB, SAND, EF-1α, UBC, UBQ, and cdc25) was assessed through real-time fluorescence quantitative PCR, GeNorm, NormFinder, BestKeeper, ΔCT, and RefFinder. The results showed that EF-1α was stably expressed in all four parts of G. elegans and was the most suitable housekeeping gene. Based on the coexpression pattern of genome, full-length transcriptome and metabolome, the key candidate targets of 18 related genes (AS, AnPRT, PRAI, IGPS, TSA, TSB, TDC, GES, G8H, 8-HGO, IS, 7-DLS, 7-DLGT, 7-DLH, LAMT, SLS, STR, and SGD) involved in the Gelsemium alkaloid biosynthesis were obtained. The expression of 18 related enzyme genes were analyzed by qRT-PCR using the housekeeping gene EF-1α as a reference. The results showed that these genes' expression and gelsenicine content trends were correlated and were likely to be involved in the biosynthesis of the Gelsemium alkaloid, gelsenicine.

This study aims to explore the mechanism of Qingkailing(QKL) Oral Preparation's heat-clearing, detoxifying, mind-tranquilizing effects based on "component-target-efficacy" network. To be specific, the potential targets of the 23 major components in QKL Oral Preparation were predicted by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction. The target genes were obtained based on UniProt. OmicsBean and STRING 10 were used for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the targets. Cytoscape 3.8.2 was employed for visualization and construction of "component-target-pathway-pharmacological effect-efficacy" network, followed by molecular docking between the 23 main active components and 15 key targets. Finally, the lipopolysaccharide(LPS)-induced RAW264.7 cells were adopted to verify the anti-inflammatory effect of six monomer components in QKL Oral Preparation. It was found that the 23 compounds affected 33 key signaling pathways through 236 related targets, such as arachidonic acid metabolism, tumor necrosis factor α(TNF-α) signaling pathway, inflammatory mediator regulation of TRP channels, cAMP signaling pathway, cGMP-PKG signaling pathway, Th17 cell differentiation, interleukin-17(IL-17) signaling pathway, neuroactive ligand-receptor intera-ction, calcium signaling pathway, and GABAergic synapse. They were involved in the anti-inflammation, immune regulation, antipyretic effect, and anti-convulsion of the prescription. The "component-target-pathway-pharmacological effect-efficacy" network of QKL Oral Preparation was constructed. Molecular docking showed that the main active components had high binding affinity to the key targets. In vitro cell experiment indicated that the six components in the prescription(hyodeoxycholic acid, baicalin, chlorogenic acid, isochlorogenic acid C, epigoitrin, geniposide) can reduce the expression of nitric oxide(NO), TNF-α, and interleukin-6(IL-6) in cell supernatant(P<0.05). Thus, the above six components may be the key pharmacodynamic substances of QKL Oral Preparation. The major components in QKL Oral Prescription, including hyodeoxycholic acid, baicalin, chlorogenic acid, isochlorogenic acid C, epigoitrin, geniposide, cholic acid, isochlorogenic acid A, and γ-aminobutyric acid, may interfere with multiple biological processes related to inflammation, immune regulation, fever, and convulsion by acting on the key protein targets such as IL-6, TNF, prostaglandin-endoperoxide synthase 2(PTGS2), arachidonate 5-lipoxygenase(ALOX5), vascular cell adhesion molecule 1(VCAM1), nitric oxide synthase 2(NOS2), prostaglandin E2 receptor EP2 subtype(PTGER2), gamma-aminobutyric acid receptor subunit alpha(GABRA), gamma-aminobutyric acid type B receptor subunit 1(GABBR1), and 4-aminobutyrate aminotransferase(ABAT). This study reveals the effective components and mechanism of QKL Oral Prescription.

This study aims to investigate the effect of Astragali Radix-Curcumae Rhizoma(AC) combination on the proliferation, migration, and invasion of colon cancer HT-29 cells based on epithelial-mesenchymal transition(EMT). HT-29 cells were respectively treated with 0, 3, 6 and 12 g·kg~(-1) AC-containing serum for 48 h. The survival and growth of cells were measured by thiazole blue(MTT) colorimetry, and the proliferation, migration, and invasion of cells were detected by 5-ethynyl-2'-deoxyuridine(EdU) test and Transwell assay. Cell apoptosis was examined by flow cytometry. The BALB/c nude mouse model of subcutaneous colon cancer xenograft was established, and then model mice were classified into blank control group, 6 g·kg~(-1) AC group, and 12 g·kg~(-1) AC group. The tumor weight and volume of mice were recorded, and the histopathological morphology of the tumor was observed based on hematoxylin-eosin(HE) staining. The expression of apoptosis-associated proteins B-cell lymphoma-2-associated X protein(Bax), cysteine-aspartic acid protease-3(caspase-3), and cleaved caspase-3, and EMT-associated proteins E-cadherin, MMP9, MMP2 and vimentin in HT-29 cells and mouse tumor tissues after the treatment of AC was determined by Western blot. The results showed that cell survival rate and the number of cells at proliferation stage decreased compared with those in the blank control group. The number of migrating and invading cells reduced and the number of apoptotic cells increased in the administration groups compared with those in the blank control group. As for the in vivo experiment, compared with the blank control group, the administration groups had small tumors with low mass and shrinkage of cells and karyopycnosis in the tumor tissue, indicating that the AC combination may improve EMT. In addition, the expression of Bcl2 and E-cadherin increased and the expression of Bax, caspase-3, cleaved caspase-3, MMP9, MMP2, and vimentin decreased in HT-29 cells and tumor tissues in each administration group. In summary, the AC combination can significantly inhibit the proliferation, invasion, migration, and EMT of HT-29 cells in vivo and in vitro and promote the apoptosis of colon cancer cells.

OBJECTIVES: To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma. METHODS: This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis. RESULTS: The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686). CONCLUSIONS AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.
