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.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance, Innovation, and Development of traditional Chinese medicine(TCM) and the spirit of the National Conference on TCM, Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis (AR) and they reached a basic consensus. In recent years, the prevalence of AR has been on the rise, threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity, and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease, western medicine features rapid onset. However, it is cost-intensive and causes severe surgical trauma, and the recurrence is common. TCM boasts diverse methods for AR, which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion, runny nose, or dysosmia in the attack stage, preventing recurrence in the remission stage, and treating refractory AR or steroid-resistant AR. In particular, acupuncture enjoys a reputation in treatment of AR, which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR, TCM regulates the psychosomatic conditions, which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine, give full play to the unique nonnegligible and irreplaceable advantages of TCM, formulate a comprehensive diagnosis and treatment scheme for learning and promotion, and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.

Objective:To investigate the risk factors of citrate accumulation in patients with liver failure treated with regional citrate anticoagulated continuous renal replacement therapy (RCA-CRRT).Methods:The clinical data of liver failure patients with RCA-CRRT admitted to department of intensive care unit (ICU) of Nantong Third People's Hospital from January 2017 to June 2020 were retrospectively analyzed. The selected patients were divided into citrate accumulation group and control group according to whether there was citrate accumulation (serum total calcium/free calcium ratio ≥ 2.4) during CRRT. The age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), mean arterial pressure (MAP), norepinephrine (NE) dose, blood lactic acid (Lac) concentration, liver function status, citrate dose, filter time and prognosis of the patients were compared between the two groups. Unconditional Logistic regression was used to analyze the risk factors for citrate accumulation.Results:Among 48 patients with RCA-CRRT and liver failure, 20 patients had citrate accumulation (accumulation group), and a total of 96 CRRTs were performed; the remaining 28 patients did not have citrate accumulation (control group), a total of 106 CRRTs were performed. There were no significant differences in age and APACHEⅡ score between the two groups. Compared with the control group, the MAP in the accumulation group was lower [mmHg (1 mmHg = 0.133 kPa): 66.9±13.6 vs. 86.4±8.3, P = 0.032], and the dosage of NE (μg/min: 16.3±8.4 vs. 5.9±2.8, P = 0.015) and lactic acid level (mmol/L: 4.89±1.45 vs. 2.98±0.87, P = 0.004) were higher, the damage of liver function was more serious [total bilirubin (TBil, μmol/L): 220.4±45.2 vs. 163.4±43.8, P = 0.012; Child-Pugh score: 12.0±2.5 vs. 8.8±1.4, P = 0.029; model for end-stage liver disease (MELD) score: 31.30±8.22 vs. 21.78±6.40, P = 0.041], hourly citric acid dosage (mmol/h: 27.4±6.9 vs. 19.3±4.9, P = 0.032) and total citric acid dosage (mmol: 3 393±809 vs. 1 819±502, P = 0.039) were higher. Although there were no significant differences in the length of ICU stay, total length of hospitalization stay and cost of hospitalization between the two groups, the 28-day mortality of the accumulation group was higher than that of the control group (60.0% vs. 28.6%, P = 0.039). Unconditional Logistic regression analysis showed that MAP [odds ratio ( OR) = 2.901, 95% confidence interval (95% CI) was 0.921-19.493, P = 0.019], NE dosage ( OR = 2.098, 95% CI was 1.923-12.342, P = 0.002), Lac level ( OR = 5.201, 95% CI was 3.211-9.433, P = 0.012), Child-Pugh score ( OR = 1.843, 95% CI was 0.437-7.420, P = 0.018), MELD score ( OR = 3.012, 95% CI was 0.384-12.843, P = 0.031), hourly citric acid dosage ( OR = 4.254, 95% CI was 1.734-11.839, P = 0.011) and total citric acid dosage ( OR = 4.109, 95% CI was 1.283-18.343, P = 0.001) were risk factors for citrate accumulation. Conclusion:In patients with tissue hypoperfusion and severe liver function damage, citrate anticoagulation should be avoided or the dosage of citric acid should be reduced, in order to avoid citrate accumulation.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China. Unfortunately, most of HCC patients were diagnosed at the intermediate or advanced stage, losing the chance to receive the surgical intervention. Locoregional interventional treatment is one of the major therapeutic options for inoperable HCC treatment and prolongs the survival of the patients. Evaluation of the efficacy of the treatment is the important to determine the further therapy strategies. Currently, the evaluation of patients’ response is mainly based on CT and MR anatomic morphological images, but characteristics of tumor biology changes can be observed earlier than the morphological changes. In the recent years, with the development of diffusion weighted imaging (DWI), its value in clinical application has been continuously explored, and it has been increasingly used for quantitative evaluation the diffusion of water molecular and microcirculation perfusion of blood flow in tumor tissue, with some progress in evaluating the tumor response. This paper mainly reviewed the recent research findings of DWI on locoregional interventional treatment for HCC, thereby providing guidance on clinical practice.

Objective:To investigate the difference of curative effect between zero-profile bridge-shaped locking cage (ROI-C) and anterior cage combined with titanium plate fixation in the treatment of two-level and three-level cervical spondylotic myelopathy.Methods:A total of 85 patients (43 males and 42 females), aged 52.3±8.0 years (range from 28 to 66 years) with bi- and three-level cervical spondylotic myelopathy who received surgical treatment from June 2017 to October 2019 were retrospectively analyzed. There were 63 cases of two levels and 22 cases of three levels. 45 cases were treated with zero-profile bridge-shaped locking cage ROI-C (ROI-C group), and 40 cases with anterior cage combined with titanium plate fixation (titanium plate group). The main observation indicators include operation time, intraoperative blood loss, cervical Cobb angle, fusion segment Cobb angle, average intervertebral height, pain visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) Score and neck disability index (NDI).Results:All of 85 patients were followed up for 16.9±2.0 months (range 12 to 22 months). The operation time of two-level ROI-C group was 110.37±8.25 min, which was shorter than 139.5±10.54 min of titanium plate group; the intraoperative blood loss was 15.74±8.10 ml, which was less than 23.71±9.70 ml of titanium plate group; the operation time of three-level ROI-C group was 130.00±5.70 min, which was shorter than 162.83±5.59 min of titanium plate group, while the difference in the intraoperative blood loss between the two groups had no statistical significance. One year after operation, Cobb angle of cervical vertebra in double and three-level ROI-C groups were 15.31°±1.55° and 15.20°±0.42°, respectively, which were largerthan 11.23°±2.03° and 9.20°±1.14° before operation; in titanium plate group, they were 15.89°±1.13° and 16.08°±1.88°, which were higher than 11.25°±2.01° and 9.00°±1.60° before operation, and the differences had statistical significance. The differences between the two groups before operation and 1 year after operation had no statistical significance. One year after operation, the VAS scores of double and three-level ROI-C groups were 1.83±0.66 points and 2.60±0.52 points, respectively, which were less than the preoperative 7.49±0.51 points and 7.60±0.52 points; the titanium plate group was 1.79±0.50 points and 2.41±0.51 points, which were less than the preoperative 7.61±0.63 points and 7.42±0.52 points, and the differences had statistical significance. There was no significant difference between the two groups before operation and 1 year after operation. One year after operation, the JOA scores of double and three-level ROI-C groups were 15.00±0.84 points and 14.70±0.95 points, respectively, which were higher than the preoperative 7.20±0.87 points and 6.60±1.27 points; the scores of titanium plate group were 15.29±0.85 points and 14.83±0.58 points, which were higher than the preoperative 6.89±1.03 points and 6.92±0.67 points, and the differences had statistical significance. The differences between the two groups had no statistical significance. The postoperative JOA improvement rate was excellent. Postoperative dysphagia occurred in 1 case (2.22%, 1/45) in ROI-C group and 8 cases (20.00%, 8/40) in titanium plate group, and the difference in the incidence rate between two groups had statistical significance ( χ2=5.32, P=0.02). Conclusion:Both ROI-C and anterior cage combined with titanium plate fixation in the treatment of double and three-level cervical spondylotic myelopathy can achieve good short-term clinical efficacy, with shorter operation time and lower incidence rate of postoperative dysphagia using ROI-C.

Objective:To explore the value of radiographic assessment of lung edema (RALE) score in evaluating the severity and prognosis of patients with acute respiratory distress syndrome (ARDS).Methods:A retrospective study was conducted. Patients with ARDS admitted to the department of intensive care unit (ICU) of Affiliated Nantong Third Hospital of Nantong University from January 2016 to November 2020 were enrolled. Clinical data of those patients were collected, and two senior radiologists who did not know the outcome of the patients independently scored each chest radiograph, the mean value of which was taken as the RALE score. The patients were divided into death group and survival group according to the 28-day prognosis. The differences of the basic data, PaO 2/FiO 2, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and RALE score between groups were analyzed. ARDS patients were classified according to the Berlin standard and RALE scores were compared between groups. Then, the correlations between RALE score and PaO 2/FiO 2, SOFA score, APACHEⅡ score were analyzed. The prognostic capacity of RALE score for 28-day prognosis of ARDS patients were analyzed by Kaplan-Meier survival curve. Results:Of the 98 ARDS patients, 62 were included in the final analysis, 39 patients survived and 23 patients died. The 28-day mortality was 37.1%. Compared with the survival group, patients in the death group were older (years old: 72.83±12.21 vs. 64.44±14.68), had lower PaO 2/FiO 2 [mmHg (1 mmHg = 0.133 kPa): 122.66±48.32 vs. 150.26±50.40], and higher SOFA score and greater difference of RALE score between the third day and the first day after admission (D3-D1 RALE score) (SOFA score: 11.26±3.91 vs. 9.04±3.72, D3-D1 RALE score: 1.35±6.42 vs. -2.74±7.35), with statistically significant differences (all P < 0.05). However, there were no significant differences in gender, cause of ARDS, APACHEⅡ score, and RALE scores on the first and the third day of admission (D1 RALE, D3 RALE) between the two groups. Among the 62 patients, there were 11 mild cases (17.7%), 36 moderate cases (58.1%), and 15 severe cases (24.2%). The D1 RALE score of patients with mild and moderate ARDS were lower than those of patients with severe ARDS (19.09±3.65, 22.58±6.79 vs. 27.07±5.23, both P < 0.05). Correlation analysis showed that D1 RALE score was negatively correlated with PaO 2/FiO 2 ( r = -0.385, P = 0.002), and positively correlated with SOFA score and APACHEⅡ score ( r1 = 0.433, r2 = 0.442, both P < 0.001). Kaplan-Meier survival curve analysis showed that the 28-day survival rate of ARDS patients in D3-D1 RALE score ≥ -1 group was significantly higher than that in D3-D1 RALE score < -1 group (73.08% vs. 55.56%; log-rank test: χ 2 = 3.979, P = 0.046). Conclusions:The RALE score is a simple and reliable non-invasive evaluation index, which can be used to evaluate the severity of ARDS patients. The difference of RALE score in early stage is helpful to identify ARDS patients with poor prognosis.

Detailed knowledge on tissue-specific metabolic reprogramming in diabetic nephropathy (DN) is vital for more accurate understanding the molecular pathological signature and developing novel therapeutic strategies. In the present study, a spatial-resolved metabolomics approach based on air flow-assisted desorption electrospray ionization (AFADESI) and matrix-assisted laser desorption ionization (MALDI) integrated mass spectrometry imaging (MSI) was proposed to investigate tissue-specific metabolic alterations in the kidneys of high-fat diet-fed and streptozotocin (STZ)-treated DN rats and the therapeutic effect of astragaloside IV, a potential anti-diabetic drug, against DN. As a result, a wide range of functional metabolites including sugars, amino acids, nucleotides and their derivatives, fatty acids, phospholipids, sphingolipids, glycerides, carnitine and its derivatives, vitamins, peptides, and metal ions associated with DN were identified and their unique distribution patterns in the rat kidney were visualized with high chemical specificity and high spatial resolution. These region-specific metabolic disturbances were ameliorated by repeated oral administration of astragaloside IV (100 mg/kg) for 12 weeks. This study provided more comprehensive and detailed information about the tissue-specific metabolic reprogramming and molecular pathological signature in the kidney of diabetic rats. These findings highlighted the promising potential of AFADESI and MALDI integrated MSI based metabolomics approach for application in metabolic kidney diseases.
