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 explore the efficacy of pancreatic kallidinogenase enteric-coated tablet combined with irbesartan tablet in the treatment of elderly patients with type 2 diabetic nephropathy(DN).Methods Elderly patients with type 2 DN were selected as the research subjects,and were randomized into control group and treatment group.The control group was given 150 mg of irbesartan tablets once a day,while the treatment group was given 240 U of pancreatic kallidinogenase enteric-coated tablets three times a day on the basis of the control group.The clinical efficacy,renal function indicators[serum creatinine(SCr),blood urea nitrogen(BUN),urinary albumin excretion rate(UAER)],hemodynamic indicators[fibrinogen(FIB),whole blood viscosity,hematocrit(HCT)],microvascular lesion indicators[vascular endothelial growth factor(VEGF),soluble intercellular adhesion molecule-1(sICAM-1)],B-ultrasound detection indicators[maximum aortic flow velocity(Vmax),minimum diastolic flow velocity(Vmin),resistance index(RI)at the renal hilum]before and after treatment and adverse drug reactions were compared between both groups.Results After treatment,the total effective rates in control group and treatment group were 85.42％and 97.92;SCr levels were(90.47±18.14)and(80.28±12.04)μmol·L-1;BUN levels were(7.24±1.34)and(6.54±1.21)mmol·L-1;UAER levels were(36.17±6.07)and(31.04±5.21)μg·min-1;FIB levels were(4.32±0.59)and(3.95±0.48)g·L-1;whole blood viscosity values were(7.38±1.15)and(6.81±0.98)mPa·s;HCT levels were(38.63±7.01)％and(36.17±6.48)％;VEGF levels were(254.18±45.59)and(212.14±40.48)pg·mL-1;human sICAM-1 levels were(336.40±61.57)and(295.30±58.46)pg·L-1;the Vmax of renal artery were(72.58±3.60)and(74.98±3.78)cm·s-1;the Vmin values were(22.48±3.14)and(24.83±3.63)cm·s-1;the RI values were 0.73±0.06 and 0.68±0.07,respectively.There were statistical differences in the above indicators between control group and treatment group(all P＜0.05).The total incidence eares of adverse drug reactions in control group and treatment group were 4.17％(2 cases/48 cases)and 8.33％(4 cases/48 cases)respectively(P＞0.05).Conclusion Pancreatic kallidinogenase enteric-coated tablet combined with irbesartan tablet can effectively improve the renal function of elderly patients with type 2 DN,improve the blood flow and delay microvascular lesion,and enhance the efficacy,therefore it is safe and effective.

This study aimed to investigate the therapeutic effects of Morinda officinalis iridoid glycosides (MOIG) on bone loss of rheumatoid arthritis (RA) rats, and the mechanism of osteoclast function and activity induced by lipopolysaccharide (LPS). RA rats were established by injecting bovin type II collagen. The Bio-ethic Committee of Zhejiang Chinese Medical University approved all experimental protocols associated with this study (IACUC-20180410-03). The collagen-induced arthritis (CIA) rats were administered drug by gavage for 8 weeks; the femoral trabecular micro-structure changes were observed in CIA rats by micro-CT; the LPS-induced osteoclasts model further observed the effect and mechanism of anti-inflammatory osteoporosis in vitro. The results indicated that MOIG could markedly increase bone mineral density (BMD) in CIA rats, improve trabecular micro-structure. In vitro studies demonstrated that MOIG could significantly inhibit osteoclastogensis and differentiation, suppress tartrate resistant acid phosphatase (TRAP) activity, F-actin ring formation, TNF receptor associated factor 6 (TRAF6) recruitment, and inhibitor of nuclear factor kappa-Bα (IκBα) degradation as well as p65 phosphorylation, thereby repressing nuclear factor kappa-B (NF-κB) signaling pathway activation. Subsequently, MOIG effectively inhibited osteoclast nuclear factor of activated T-cells c1 (NFATc1) and cellular oncogene Fos (c-Fos) expression, as well as bone resorption related protein activity including matrix metalloprotein 9 (MMP-9) and cathepsin K (CtsK). Meanwhile, MOIG also repressed the phosphorylation expression of Janus activating kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3), thereby inhibiting JAK2/STAT3 signaling pathway activation. Moreover, further studies found that MOIG could suppress glycogen synthase kinase-3β (GSK-3β) activity, and GSK-3β gene silencing could markedly inhibit oetsoclast F-actin ring formation as well as the phosphorylation expression of p65 and STAT3. Of note, compared with GSK-3β gene silencing group, there was no significant difference in the group treated with both MOIG with GSK-3β gene silencing simultaneously. Thus, the results suggested that MOIG may inhibit NF-κB signaling pathway and JAK2/STAT3 signaling pathway activation via regulating GSK-3β, thereby alleviating bone destruction in RA.

OBJECTIVE: To investigate a new noninvasive diagnostic model for nonalcoholic fatty liver disease (NAFLD) based on features of tongue images. METHODS: Healthy controls and volunteers confirmed to have NAFLD by liver ultrasound were recruited from China-Japan Friendship Hospital between September 2018 and May 2019, then the anthropometric indexes and sampled tongue images were measured. The tongue images were labeled by features, based on a brief protocol, without knowing any other clinical data, after a series of corrections and data cleaning. The algorithm was trained on images using labels and several anthropometric indexes for inputs, utilizing machine learning technology. Finally, a logistic regression algorithm and a decision tree model were constructed as 2 diagnostic models for NAFLD. RESULTS: A total of 720 subjects were enrolled in this study, including 432 patients with NAFLD and 288 healthy volunteers. Of them, 482 were randomly allocated into the training set and 238 into the validation set. The diagnostic model based on logistic regression exhibited excellent performance: in validation set, it achieved an accuracy of 86.98%, sensitivity of 91.43%, and specificity of 80.61%; with an area under the curve (AUC) of 0.93 [95% confidence interval (CI) 0.68-0.98]. The decision tree model achieved an accuracy of 81.09%, sensitivity of 91.43%, and specificity of 66.33%; with an AUC of 0.89 (95% CI 0.66-0.92) in validation set. CONCLUSIONS The features of tongue images were associated with NAFLD. Both the 2 diagnostic models, which would be convenient, noninvasive, lightweight, rapid, and inexpensive technical references for early screening, can accurately distinguish NAFLD and are worth further study.

Aim To predict and validate the mechanism of wenshen xuanbi tang(WSXBT) in treatment of osteoporosis (OP) based on network pharmacology, molecular docking techniques and in vivo experimental techniques. Methods Network pharmacology was used to screen the key ingredients and core targets of WSXBT for the treatment of osteoporosis. Metascape database was used for gene ontology (GO) biological process enrichment analysis and kyoto encyclopedia of genes and genomes (KEGG) signaling pathway enrichment analysis of core targets. AutoDockTools 1. 5. 7 software was applied in molecular docking to simulate the binding activity of key active ingredients to core targets. To study the efficacy of WSXBT on rats with osteoporosis and to verify the related targets and pathways, rat models of osteoporosis were established by excising the bilateral ovaries of rats. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum OPG, PINP and RANKL content. Biomechanical tester was applied to test the biomechanics of rat femurs. Micro-CT was applied to detect the femoral bone density. Then, Western blot was employed to measure the protein expression levels of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt). Results A total of 156 active ingredients of WSXBT were screened, involving 229 potential targets, 23 core targets and 145 signaling pathways. The molecular docking results showed that five key ingredients, including quercetin, kaempferol, naringenin, isobavachin and licochalcone a, possessed good binding ability to the core targets of PIK3R1 and AKT1. The results of in vivo experiments showed that WSXBT could significantly increase bone density, improve bone tissue microstructure, enhance femur biomechanics and increase PINP expression and OPG/RANKL ratio in rats with osteoporosis. Results of WB showed that WSXBT significantly increased p-PI3K/PI3K and p-Akt/Akt ratios. Conclusions WSXBT could improve bone mineral density in postmenopausal osteoporotic rats through PI3K/ Akt signaling pathway and increasing OPG/RANKL ratio.
