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.

Novel coronavirus Omicron variant infection can cause severe illness and even death in certain populations. Omicron variant infection may lead to systemic inflammatory response, coagulation disorder, multi-organ dysfunction and other pathophysiological changes, which are different from other Novel coronavirus variants to a certain extent, so therapeutic strategies should not be the same. The National Medical Center for Major Public Health Events invited experts in fields of infectious diseases, respiratory medicine, intensive care, pediatrics and fever clinic to develop this quick guideline based on the current best evidence and extensive clinical practices. This quick guideline aims to standardize the diagnosis and treatment of novel coronavirus Omicron infection, and to improve the disease management abilities of clinicians.

ObjectiveTo investigate the effect and mechanism of Guilu Erxiangao on Alzheimer's disease （AD） model rats induced by hydrocortisone and amyloid β-protein（Aβ） based on the theory of kidney-brain correlation. MethodIntraperitoneal injection of hydrocortisone and intracerebroventricular injection of Aβ were performed to induce AD in rats， and different concentrations of Guilu Erxiangao were used for intervention. The indexes of hippocampus， kidney and adrenal gland were measured， and the spatial learning and memory ability of AD rats was observed by Morris water maze experiment. The levels of testosterone （T） and corticosterone （CORT） in serum samples were determined by enzyme-linked immunosorbent assay （ELISA）. Liquid chromatography-mass spectrometry （LC-MS） was used to collect and analyze the serum metabolic data of model rats. The active components and corresponding targets of Guilu Erxiangao were collected using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP）， a Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM） and Traditional Chinese Medicine Integrated Database（TCMID）. GeneCards and Online Mendelian Inheritance in Man （OMIM） were retrieved to obtain AD-related targets， and protein-protein interaction （PPI） network was constructed to perform gene ontology （GO）and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis. The expression level of interleukin-6 （IL-6） in the hippocampus of rats was detected by Western blot. ResultCompared with the model group， the low-， medium- and high-dose groups of Guilu Erxiangao exhibited significantly increased hippocampus index， kidney index and adrenal gland index， reduced CORT levels in serum and down-regulated IL-6 levels in hippocampal tissues. According to the results of water maze experiment， as compared with the model group， the platform crossing times of rats was significantly increased in the low- and high-dose groups of Guilu Erxiangao， with evidently prolonged distance traveled in quadrant Ⅲ （%） and time in quadrant Ⅲ （%）. A total of 24 serum differential metabolites associated with AD were identified by LC-MS， and 50 high-frequency common compounds and 187 high-frequency common targets for AD treatment were screened by network pharmacology method. Results demonstrated phosphatidylinositol 3-kinases（PI3K）/protein kinase B（Akt） signaling pathway plays an important role in the complex AD pathological mechanism. ConclusionGuilu Erxiangao can significantly improve the cognitive dysfunction of AD model rats induced by hydrocortisone and Aβ， reduce serum CORT levels and IL-6 levels in hippocampal tissues， and regulate the metabolic level， which provides a reference for its clinical application.

ObjectiveTo explore the effect of Qishengwan on ileal flora during its treatment of Alzheimer's disease （AD） under the guidance of the theory of "interior-exterior relationship between heart and small intestine". MethodThe AD model was established by bilateral intraventricular injection of β-amyloid 1-42 （Aβ_1-42）. The rats were then randomly divided into the blank group， sham-operated group， model group， low-， medium-， and high-dose （5.6， 11.2，22.4 g·kg^-1·d^-1） Qishengwan groups， and donepezil （0.46 mg·kg^-1·d^-1） group. After medication for 28 successive days， the spatial memory ability of rats was observed in water maze test， and the levels of Aβ_1-42， nuclear transcription factor-κB （NF-κB）， tumor necrosis factor-α （TNF-α）， and interleukin-6 （IL-6） in the hippocampus were analyzed by enzyme-linked immunosorbent assay （ELISA）. Additionally， the contents of the ileum were collected and subjected to 16SrRNA-sequencing analysis for figuring out the changes in ileal flora. ResultCompared with the blank group and sham-operated group， the model group exhibited significantly reduced stay time in the target quadrant and number of target quadrant and platform crossings （P<0.05， P<0.01） and elevated Aβ_1-42 content in the hippocampus （P<0.01） and central inflammatory factors NF-κB， TNF-α， and IL-6 （P<0.05， P<0.01）. Compared with the model group， Qishengwan at each dose significantly alleviated the impaired spatial memory function （P<0.05， P<0.01）， improved the deposition of Aβ_1-42 in the hippocampus of rats （P<0.05， P<0.01）， and reduced the expression of central nervous system inflammatory factors （P<0.05， P<0.01）， thus exerting a good therapeutic effect on AD rats. The 16SrRNA-sequencing analysis results showed that the structure of the ileal flora in the model group was significantly separated from those in the blank group and sham-operated group. The abundance of Lachnospiraceae NK4A136 group was significantly increased （P<0.01）， while that of Escherichia-Shigella was reduced （P<0.05， P<0.01）. Qishengwan at each dose significantly changed the ileal flora structure and regulated the relative abundance of Lachnospiraceae NK4A136 group， Escherichia-Shigella， and Ruminococcaceae. ConclusionQishengwan has a positive therapeutic effect on AD. It can significantly enhance the memory and cognitive abilities in AD rats， which may be related to its regulation of the structure of rat ileal flora and the relative abundance of Lachnospiraceae NK4A136 group， Escherichia-Shigella， and Ruminococcaceae， the attenuation of the central neuroinflammatory response， and the reduction of central Aβ_1-42 deposition.

Objective:To evaluate the effects of the cassette 14C-urea breath test kit, scintillation sampling bottle (solid-state scintillation method) and liquid scintillation 14C-urea breath test kit in the diagnosis of Helicobacter pylori ( H. pylori) infection. Methods:From January 7 to October 28, 2020, 239 patients were enrolled who visited Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, the Second Affiliated Hospital of Zhejiang University School of Medicine and the First Affiliated Hospital of Nanchang University. All subjects first received 14C-urea breath test.Within >1 to <7 days after gas collection, mucosal tissues were taken under gastroscopy for gold standard test, including biopsy and rapid urease test (RUT). If both biopsy and RUT indicated H. pylori positive, the result of gold standard test was H. pylori positive, and if both were negative, the result of gold standard test was H. pylori negative. If the results of biopsy and RUT were inconsistent, they were not included in the subsequent analysis. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were analyzed. The safety of the test was evaluated by whether there were any adverse events during the test. Descriptive methods were used for statistical analysis. Results:Among the 239 subjects, 12 cases did not complete the test, 227 subjects finally completed the test. The test completion rate was 95.0% (227/239). No.008 patient was only included in the analysis of cassette 14C-urea breath test kit and scintillation sampling bottle because of lacking the result of liquid scintillation breath test. The results of gold standard test showed that among 227 patients, 87 cases were H. pylori positive, 118 cases were H. pylori negative. The results of biopsy and RUT were inconsistent in 22 cases, so they were not included in the subsequent analysis. Excluding No.008 patient, the results of gold standard test showed that 86 cases were H. pylori positive and 118 cases were negative. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cassette 14C-urea breath test kit, scintillation sampling bottle, and the liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were 91.9%, 100.0%, 96.6%, 100.0% and 94.4%, respectively; 95.4%, 97.5%, 96.6%, 96.5% and 96.6%, respectively; and 96.5%, 99.2%, 98.0%, 98.8% and 97.5%, respectively. Only one adverse event (right upper abdominal pain after eating) occurred. Combined with the patients condition, the adverse event was determined as the onset of chronic cholecystitis and it might not be related to the test medication. Conclusions:Cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit have reliable performance, good safety, and high sensitivity, specificity and accuracy in the diagnosis of H. pylori infection, which are worthy of clinical application.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.
