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.

During the treatment of non-small cell lung cancer ( NSCLC) , many patients have developed drug resistance due to the use of targeted EGFR inhibitors. The main reasons for drug resistance are EGFR site mutations and bypass activation. Activation of ALK pathway is one of the major types of bypass activation. A recent authoritative study indicates that ALK is closely related to immunotherapy. This article reviews the treatment of ALK in tumors from three aspects: the structure and physiological function of ALK, the small molecule inhibitor of ALK, the biological function of ALK and its related treatment methods for NSCLC, and prospects future directions for better application of ALK in the treatment of NSCLC.

Objective:In this retrospective study, the accuracy and outcomes of segmental Le Fort I surgery with the aid of 3D-printed surgical templates and occlusal splints and dental model surgery were evaluated.Methods:Clinical data of patients receiving segmental Le Fort I surgery in the Department of Orthognathic and Temporo-Mandibular Joint Surgery of West China Stomatological Hospital of Sichuan University from January 2014 to June 2019 were retrospectively analyzed. The accuracy of virtual surgical planning(VSP) and the difference between VSP and dental model surgery were evaluated by postoperative complications, color distance maps, and quantitative accuracy analysis.The amount of surgical displacement of the maxilla in the three-dimensional direction before and after surgery, the occurrence of postoperative complications and the patients'satisfaction survey were analyzed in both groups. Paired t-tests were used for the linear distance and angle between the preoperative design model and the final virtual surgery model in the digital surgery group. Independent samples t-test was used for each marker point’s preoperative and postoperative displacements in the three-dimensional direction between the digital surgery group and the dental model group. The proportion of postoperative complications in the 2 groups was tested using the Pearson chi-square test, and the difference was considered statistically significant at P<0.05. Results:There were 129 patients in the digital surgery group, 35 males and 94 females, aged (24.5±6.5) years, and 92 patients in the dental model surgery group, 28 males and 64 females, aged (27.7±5.4) years.The overall mean linear difference was 1.23±0.35 mm, and the overall mean angular difference was 2.48°±0.31°. The vertical displacement of U3R, U6L in the digital surgery group was (6.72±1.57)mm and (4.73±2.07)mm. The vertical displacement of U3R, U6L in the group of dental model surgery was (4.07±2.14)mm and (1.62±1.82)mm.The significant deviation difference in U3R-Y and U6L-Y between two groups could be detected. The complications in two groups showed a significant difference. Except for one case of root injury, there was no serious complication recorded in the digital surgery group. However, there were three cases of palatal fistulas, four cases of root injury and two cases of bone dehiscence in the dental model group. 94.5% of patients in the digital surgery group are satisfied with the surgical results, while 89.1% in the dental model group.Conclusion:Compared with dental model surgery, segmental Le Fort I surgery is highly accurate under the guidance of surgical templates and occlusal splint which has better postoperative results and effectively reduces the occurrence of surgical complications.

Objective To investigate the clinical effect of air moxibustion combined with pushpin-like needle acupuncture,which is formulated based on the"suppressing wood-supporting earth"theory in the doctrine of the five elements of Traditional Chinese Medicine(TCM),in the treatment of pain,nausea and vomiting after transcatheter arterial chemoembolization(TACE).Methods A total of 160 patients with hepatocellular carcinoma,who were admitted to the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine of China to receive initial TACE between July 2020 and June 2023,were enrolled in this study.The patients were randomly divided into 4 groups with 40 patients in each group.The patients of the control group received TACE with conventional nursing care,the patients of the pushpin-like needle group received pushpin-like needle acupuncture on the basis of the control group,the patients of the air moxibustion group received air moxibustion treatment on the basis of the control group,and the patients of the combination group received air moxibustion combined with pushpin-like needle acupuncture on the basis of the control group.The post-TACE pain degree(VAS scoring)and nausea/vomiting extent(INVR scoring)were compared between each other among the four groups.Results The differences in the VAS score and INVR score(including main effect and interaction effect)between each other among the four groups were statistically significant(all P＜0.05).Statistically significant differences in the VAS score and INVR score existed between the control group and the other three groups(all P＜0.05).The differences in the VAS score and INVR score between combination group and pushpin-like needle group,as well as between combination group and air moxibustion group were statistically significant(both P＜0.05).Conclusion Air moxibustion combined with pushpin-like needle acupuncture can effectively and remarkably relieve post-TACE pain,nausea and vomiting,which is superior to simple use of air moxibustion or pushpin-like needle acupuncture.Therefor,the combination use of air moxibustion and pushpin-like needle acupuncture should be popularized in clinical practice.

Objective: To understand the basic characteristics of previously reported patients with hepatitis C and analyze the related factors affecting their antiviral treatment. Methods: A convenient sampling method was adopted. Patients who had been previously diagnosed with hepatitis C in the Wenshan Prefecture of Yunnan Province and Xuzhou City of Jiangsu Province were contacted by telephone for an interview study. The Andersen health service utilization behavior model and related literature were used to design the research framework for antiviral treatment in previously reported hepatitis C patients. A step-by-step multivariate regression analysis was used in previously reported hepatitis C patients treated with antiviral therapy. Results: A total of 483 hepatitis C patients, aged 51.73 ± 12.06 years, were investigated. The proportion of male, agricultural occupants who were registered permanent residents, farmers and migrant workers was 65.24%, 67.49%, and 58.18%, respectively. Han ethnicity (70.81%), married (77.02%), and junior high school and below educational level (82.61%) were the main ones. Multivariate logistic regression analysis results showed that married patients with hepatitis C (OR = 3.19, 95% CI: 1.93-5.25, compared with unmarried, divorced, and widowed patients) with high school education or above (OR = 2.54, 95% CI: 1.54-4.20, compared with patients with junior high school education or below) were more likely to receive antiviral treatment in the predisposition module. Patients with severe self-perceived hepatitis C in the need factor module (compared with patients with mild self-perceived disease, OR = 3.36, 95% CI: 2.09-5.40) were more likely to receive treatment. In the competency module, the family's per capita monthly income was more than 1,000 yuan (compared with patients with per capita monthly income below 1,000 yuan, OR = 1.59, 95% CI: 1.02-2.47), and the patients had a high level of awareness of hepatitis C knowledge (compared with patients with a low level of knowledge, OR = 1.54, 95% CI: 1.01-2.35), and the family members who knew the patient's infection status (compared with patients with an unknown infection status, OR = 4.59, 95% CI: 2.24-9.39) were more likely to receive antiviral treatment. Conclusion: Different income, educational, and marital statuses are related to antiviral treatment behavior in hepatitis C patients. Family support of hepatitis C patients receiving hepatitis C-related knowledge and their families knowing the infection status is more important in promoting the antiviral treatment of patients, suggesting that in the future, we should further strengthen the hepatitis C knowledge of hepatitis C patients, especially the family support of hepatitis C patients' families in treatment.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective:To assess the relationship between appendicular skeletal muscle mass (ASM) and ankle brachial index (ABI) among patients with type 2 diabetes.Methods:In this cross-sectional study, from July 2018 to March 2019, a total of 278 patients with type 2 diabetes treated in Zhongda Hospital were enrolled in this study, and there were 158 males and 120 females. General information and clinical biochemical parameters and ABI in the patients were collected. The appendicular muscle mass was quantitatively measured with body composition analyzer to achieve ASM. And the appendicular skeletal muscle mass index (ASMI), skeletal muscle index (SMI), and appendicular skeletal muscle mass/body mass index (ASM/BMI) were calculated respectively. Correlation analysis and multiple linear regression analyses with different adjustment models were conducted to analyze the correlation between ABI and above-mentioned indexes.Results:The Pearson correlation analysis showed that ABI had significant positive correlation with ASM, ASMI and ASM/BMI ( r=0.14, 0.13, 0.13, all P<0.05), but a marginal relation with SMI ( r=0.116, P=0.053). Multiple linear regression analysis suggested that ASMI ( β=0.053, 95% CI: 0.006-0.101, P=0.027) and AMI/ABI ( β=0.347, 95% CI: 0.040-0.654, P=0.027) were significantly related to ABI. Conclusion:ASM is positively associated with ABI in patients with type 2 diabetes.
