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 monitor the changes of voriconazole minimum concentration(C_min) in patients with hematological diseases, and evaluate the factors influencing and adverse reactions of voriconazole clearance in patients with hematological diseases, so as to provide a theoretical basis for reasonable clinical use of voriconazole. METHODS: 136 patients with hematological diseases who used voriconazole in Wuhan NO.1 Hospital from May 2018 to December 2019 were selected. The correlation between C-reactive protein, albumin, creatinine and voriconazole C_min were analyzed, and the changes of voriconazole C_min after glucocorticoid treatment was also detected. In addition, stratified analysis was used to explore the adverse events of voriconazole. RESULTS: Among 136 patients, 77 were male (56.62%) and 59 were female (43.38%). There were positive correlations between voriconazole C_min and C-reactive protein and creatinine levels (r=0.277, r=0.208), while voriconazole C_min was negatively correlated with albumin level (r=-2.673). Voriconazole C_min in patients treated with glucocorticoid was decreased significantly (P<0.05). In addition, sratified analysis of voriconazole C_min showed that compared with voriconazole C_min 1.0-5.0 mg/L group, the incidence of adverse reactions of visual impairment in voriconazole C_min> 5.0 mg/L group was increased (χ²=4.318, P=0.038). CONCLUSION The levels of C-reactive protein, albumin and creatinine are closely related to the voriconazole C_min, which indicate that inflammation and hyponutrition may prevent the clearance of voriconazole in patients with hematological diseases. It is necessary to monitor the voriconazole C_min of patients with hematological diseases, and adjust the dosage in time to reduce adverse reactions.

OBJECTIVE: To evaluate the antidiarrheal effect of ethanol extract of Glycyrrhiza uralensis Fisch root (GFR) in vivo and jejunal contraction in vitro. METHODS: In vivo, 50 mice were divided into negative control, positive control (verapamil), low-, medium- and high-dose GFR (250, 500, 1,000 mg/kg) groups by a random number table, 10 mice in each group. The antidiarrheal activity was evaluated in castor oil-induced diarrhea mice model by evacuation index (EI). In vitro, the effects of GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) on the spontaneous contraction of isolated smooth muscle of rabbit jejunum and contraction of pretreated by Acetylcholine (ACh, 10 µmol/L) and KCl (60 mmol/L) were observed for 200 s. In addition, CaCl₂ was accumulated to further study its mechanism after pretreating jejunal smooth muscle with GFR (1 and 3 g/L) or verapamil (0.03 and 0.1 µmol/L) in a Ca²⁺-free-high-K⁺ solution containing ethylene diamine tetraacetic acid (EDTA). RESULTS: GFR (500 and 1,000 mg/kg) significantly reduced EI in castor oil-induced diarrhea model mice (P<0.01). Meanwhile, GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) inhibited the spontaneous contraction of rabbit jejunum (P<0.05 or P<0.01). Contraction of jejunums samples pretreated by ACh and KCl with 50% effective concentration (EC₅₀) values was 1.05 (0.71-1.24), 0.34 (0.29-0.41) and 0.15 (0.11-0.20) g/L, respectively. In addition, GFR moved the concentration-effect curve of CaCl₂ down to the right, showing a similar effect to verapamil. CONCLUSIONS GFR can effectively against diarrhea and inhibit intestinal contraction, and these antidiarrheal effects may be based on blocking L-type Ca²⁺ channels and muscarinic receptors.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To analyze the apply effect of radiofrequency ablation assisted associating liver partition and portal vein ligation for staged hepatectomy (RALPPS) in liver cancer patients with insufficient future liver remnant (FLR).Methods:The data of 29 patients who underwent RALPPS in the First Affiliated Hospital of the Army Military Medical University from June 2014 to July 2020 were analyzed, including 25 males and 4 females, aged (46.6±9.9) years. The patients were divided into the second stage group (completed the second stage operation, n=18) and the first stage group (completed only the first stage operation, n=11) according to whether they had successfully completed the second stage operation. FLR, percentage of FLR in standard liver volume (percentage of FLR), growth rate of FLR, liver function after operation, operation time and radiofrequency ablation time of first stage operation, surgical complications were compared between the two groups. Results:The percentage of FLR before the first stage operation was (30.0±7.0)% in 29 patients, and the second stage operation was completed in 18 patients (62.1%). After the first stage operation, the aspartate aminotransferase and alanine aminotransferase in the second stage group were 519.0 (362.9, 696.0) U/L and 391.8 (297.2, 591.1) U/L, which were better than those of the first stage group 931.0 (711.7, 1131.9) U/L and 851.3 (426.6, 888.0) U/L (both P<0.05). There was no significant difference between the two groups in FLR and percentage of FLR before the first stage operation, duration time, amount of bleeding and time of radiofrequency ablation of the first stage operation (all P>0.05). In the second stage group, the interval between two operations was (21.6±6.7) days, the FLR before the second stage operation was (623.2±101.8) cm 3, the FLR percentage was (49.0±7.0)%, and the FLR growth rate was (19.0±5.0)%. In the first stage group, there were 11 patients (100.0%) who developed complication after first stage operation, induding 7 patients (63.6%) with complication above Clavien-Dindo grade Ⅲb. In the second stage group, 18 patients (100.0%) developed complication after the first stage operation. There were no complication above grade Ⅲb. The causes of 11 patients who did not completed secondary surgery included poor liver function and insufficient FLR in 4 patients, tumor progression in 6 patients, and death in 1 patient. Conclusion:RALPPS is a therapeutic option for liver cancer patients with insufficient FLR, and the therapeutic effect is reasonable.

Exosomes are lipid bilayer membranous vesicles actively secreted by various cells in the organism， which are like nanoparticles and have messenger targeting. Combining with the theory of supramolecular "Qi chromatography" of traditional Chinese medicine （TCM）， research ideas and strategies of modernization of TCM can be constructed. Exosomes are secreted by cells， and the membrane contains nucleic acids， proteins， lipids and small molecular metabolites and others， which can accurately coordinate the functions of each cell， concentrate and transmit the functional information of the parent cell， and is the concise form of reflecting cell functions. At the same time， it is loaded with the "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM. If the "imprinted templates" carrying rules among the gene-protein-lipid-small molecules wrapped in it is studied， the modern experimental research ideas and strategies of TCM theory can be established for revealing the functions of the body's meridians and viscera. Firstly， the present situation of exosomes， including discovery， secretion， characteristics， functions， attribution， uptake， research methods and application status， were reviewed in this paper. And the natural properties of its precise messenger targeted delivery vehicle were elaborated， reflecting the operation law of microscopic substances in meridians and viscera. Secondly， to explore it as an important carrier of the concentrated "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM， and integrating the research methods of exosomes and supramolecular chemistry of TCM， this paper proposes experimental research ideas and strategies on the microscopic material basis of meridians and viscera， compatibility of TCM compound， and targeting of TCM targeted preparations.

In the era of artificial intelligence based on big data， data acquisition， storage and processing are more convenient， which provides a guarantee for accelerating the development of traditional Chinese medicine （TCM）， but it has not yet achieved organic integration with TCM theory. Based on preliminary research on the supramolecular "Qi chromatography" theory of TCM， combined with the current development trend of artificial intelligence， this paper analyzed the biological intelligence attribute of the function of TCM supramolecular "imprinting template"， in order to provide reference for the development of TCM drug innovation. Both the human body and Chinese materia medica are giant complex supramolecular bodies evolved from natural organisms. According to the "imprinting template"， the "social molecules" are controlled step by step to form the meridians and viscera. The interaction produces the original theory of TCM， in which the self-recognition， self-assembly， self-organization and self-replication of the "imprinting template" reflect the "intelligence" function attributes：the human body uses the "imprinting template" to self-identify and sense the ingredients of TCM， and store the memory information database in the meridian and collateral organs in the form of "imprinting template"， and then pass the "imprinting template". The comparison， analysis， and judgment of imprinting templates guide the self-assembly， self-organization and self-replication among "molecular society"， synthesize biological machines， produce biological functions， repair or strengthen biological supramolecular bodies， and present the most basic "intelligence" attribute. This suggests that the theory of theory-method-prescription-medicine of TCM is the weak embodiment of biological "intelligence"， while the human brain function is the strong embodiment of biological "intelligence". Since the intelligent function of supramolecular "imprinting template" runs through the natural world， artificial intelligence that can characterize the strong "intelligence" form of the human brain will also be integrated into all aspects of the natural world， suggesting the development direction of "intelligence" functionalization of drug innovation mode.

OBJECTIVE: To observe the therapeutic effect between acupuncture combined with medication and simple medication on migraine and cerebral hemodynamics. METHODS: A total of 120 patients with migraine were randomized into an acupuncture plus medication group (60 cases, 3 cases dropped off) and a medication group (60 cases, 6 cases dropped off). In the medication group, flunarizine hydrochloride capsule was given orally before sleep, 10 mg a day. On the basis of the treatment in the medication group, acupuncture was applied at Sizhukong (TE 23), Shuaigu (GB 8), Taiyang (EX-HN 5), Fengchi (GB 20) and etc. in the acupuncture plus medication group, 30 min each time, once a day. Treatment for 4 weeks was required in both groups. Before and after treatment, the visual analogue scale (VAS) score, indexes of cerebral hemodynamic [blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), vertebral artery (VA) and basilar artery (BA)] and total TCM syndrome score were observed, and the clinical therapeutic effect and the incidence of the adverse events were evaluated in both groups. RESULTS: Compared before treatment, the VAS scores, the blood flow velocity of ACA, MCA, PCA, VA, BA and the total TCM syndrome scores were decreased in both groups ( CONCLUSION Acupuncture combined with flunarizine hydrochloride capsule can effectively relieve the pain in patients with migraine, reduce the cerebral blood flow velocity, the efficacy is superior to simple flunarizine hydrochloride capsule.

A 19-year-old male patient who suffered from sudden and repeated multiple organ dysfunction syndrome one month after the bar removal procedure of Nuss surgery for pectus excavatum was admitted to our department. With organ function supportive treatment, the etiology was finally identified to be a bone spur located at the inner border of the left costa due to repeated friction between the implanted steel bar and the rib, which damaged the heart repeatedly and induced the consequent acute cardiac tamponade. After operation, the patient was successfully managed and discharged. Follow-ups till three years indicated a good recovery.

Gout is the second largest metabolic disease in China， which can cause joint tissue damage and a variety of chronic diseases， and seriously affect human life and health. The increase in uric acid caused by disorder of purine metabolism or abnormal uric acid excretion is the biochemical basis of its pathogenesis. Western medical treatment mainly uses anti-inflammatory drugs such as colchicine， non-steroidal anti-inflammatory drugs， and uric acid lowering drugs such as febuxostat and benzbromarone， which have obvious effects， but there are problems such as easy to recurrence after drug withdrawal and more adverse reactions. Traditional Chinese medicine （TCM） has a long history in the treatment of gout， and has the advantages of multi-channel， multi-target， and multi-level symptomatic treatment. It exerts therapeutic effects through lowering uric acid， anti-inflammatory， anti-oxidation， and protecting the kidneys. Its curative effect is obvious and the adverse reaction rate is low. In recent years， there have been many studies on the mechanism of TCM for gout animal models. Based on the review of relevant literature in recent years， this article has systematically sorted out the pathogenesis of gout， the mechanism of TCM for gout and related experimental design. The paper summarized and analyzed the mechanism of TCM in the treatment of gout from the aspects of regulating the level of inflammatory factors， inhibiting oxidation reaction， reducing uric acid and regulating signaling pathway， so as to provide reference for the research and development of drugs for gout.
