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 establish an ideal modeling method for diarrhea predominant irritable bowel syndrome(IBS-D)with anxiely and depression in rats,and to provide a basis for the clinical study of IBS-D.Methods 60 rats were used in this study.(1)At first,20 rats were randomly divided into blank,3%acetic acid enema,4%acetic acid enema,and 5%acetic acid enema groups.After the modeling and observation period,the diarrhea status and the degree of colon injury caused by different modeling concentrations were observed by diarrhea related index and colon histopathology.(2)After the optimal modeling concentration was assessed,40 rats were randomly divided into control(a),acetic acid enema(b),acetic acid+binding(c),and acetic acid+binding+tail clip(d)groups and correspondingly treated for 8 days.After the treatments,the general condition,diarrhea-related index,open field test(OFT)score,and colonic histopathology of rats were evaluated.Results(1)Compared with the blank group,the fecal trait score of 4%acetic acid enema group was increased on days 1 to 3 after intervention(P＜0.001),and gradually decreased on days 4 to 7 after intervention.After 1 week,there was no significant difference between the fecal trait score and that of the blank group(P＞0.05).Body weight was lower(P＜0.01),fecal water content was higher(P＜0.001).Compared with blank group,body weight of the 5%acetic acid enema group was decreased(P＜0.001),the fecal trait score and diarrhea index were increased(P＜0.01).No significant difference was found between 3%acetic acid enema and blank groups.The pathological colon tissue showed that,compared with the blank group,the mucosal structure of the 4%acetic acid enema group was complete with a small amount of inflammatory cell infiltration,and the pathological tissue score showed no significant difference(P＞0.05),whereas the 5%acetic acid enema had a medium to large amount of inflammatory cell infiltration,and the pathological tissue score was increased(P＜0.01).(2)Compared with group a,group b had lower body weight(P＜0.001),and higher fecal trait score,fecal water content and diarrhea index(P＜0.01).Compared with a and b groups,the body weight of c and d groups was lower(P＜0.001),the fecal traits score,fecal water content,and diarrhea index were increased(P＜0.01),and the colon running time was decreased(P＜0.01).Compared with group c,Fecal water content in group D was higher(P＜0.001).In the OFT score,compared with a and b groups,the OFT distance,standing times,and upright times in c and d groups were lower(P＜0.05).Compared with c,the OFT distance,standing times,and upright times in d group were lower(P＜0.05).The pathological tissue of colon showed that the mucosal structure of the four groups was complete,and there were different degrees of inflammatory cell infiltration.The pathological tissue scores of groups c and d were higher than those of groups a and b(P＜0.05).Conclusions The 4%acetic acid concentration is appropriate for IBS-D modeling.After superposition and binding,the IBS-D diarrhea and internal hypersensitivity characteristic state can be better simulated.After superposition of a tail clip,the IBS-D model of liver stagnation and spleen deficiency can be established successfully.

Objective:This paper aims to analyze the current status,characteristics,and problems of the policy text of China's chronic disease from the perspective of full-cycle,and provide a reference for subsequent policy optimization.Methods:The author selected 104 policy documents on chronic disease published at the national level from 2009 to 2023,used content analysis method,constructed a two-dimensional analysis framework of"policy tools-full-cycle management",and carried out one-dimensional quantitative analysis and two-dimensional cross-analysis.Results:The application of policy tools is obviously unbalanced,with supply-type policy tools accounting for as much as 63.23％,and demand-type policy tools used the least,only 10.51％.In the dimension of full-cycle management,the proportions of prevention,prevention and treatment,treatment,treatment and rehabilitation,health care,and full-cycle stages are 21.01％,24.58％,28.89％,7.32％,4.69％and 13.51％respectively.It is noteworthy that the proportions of the treatment and rehabilitation,and health care stages are relatively low.All stages of chronic disease health management interact frequently with supply-type policies,and the treatment and rehabilitation,health care and full-cycle stages cross less with demand-type policy tools.Conclusion:It is necessary to adjust the proportion of policy tools,strengthen their internal coordination,improve the top-level design of treatment and rehabilitation and health care,enhance the synergistic interaction between various types of policy tools and full-cycle management,and improve the overall effectiveness of policies.

OBJECTIVE: To retrospectively analyze clinical effect of 3D mirror printing combining with minimally invasive percutaneous plate osteosynthesis(MIPPO) technology in the treatment of adult clavicle fracture. METHODS: The clinical data of 32 adult patients with collarbone AllmanⅠdisplacement of fracture who had undergone the combination of 3D mirror printing with MIPPO technology treatment were collected from October 2019 to October 2020. There were 19 males and 13 females, aged from 19 to 55 years old with an average of(34.12±16.42) years old. According to Allman classification, there were 14 cases of AllmanⅠb and 18 cases of AllmanⅠc. Fracture occurred on the left in 17 cases and on the right in 15 cases. Postoperative complications, operation time, incision length, intraoperative blood loss, the number of fluoroscopies, fracture healing time of all patients were retrospectively analyzed, and the curative effect was evaluated by Constant-Murley shoulder joint score before operation, 1 and 6 months after operation. RESULTS: All the 32 patients were followed up for 6 to 8 months, with an average of (6.67±2.13) months. All the patients did not have postoperative complications such as incision infection and skin numbness in the operating area. The operation time was (35.37±4.28) min. The incision length was (3.78±0.45) cm. Intraoperative blood loss was(37.23±4.76) ml. The number of fluoroscopies was(3.12±0.47) times. Fracture healing time was (8.18±2.58) weeks. Constant-Murley shoulder joint score of the affected side at 1 and 6 months after operation was 81.08±3.92 and 98.03±1.05 respectively, which had a significant difference compared with 54.62±5.25 before operation(P<0.05). According to Constant-Murley shoulder function score at 6 months after operation, 30 cases were excellent and 2 cases were good. CONCLUSION 3D mirror printing can effectively assist MIPPO technique in the treatment of adult clavicle AllmanⅠdisplaced fracture. It not only has the advantages of less trauma and fewer complications of the MIPPO technique, but also can further shorten the operation time and improve the operation maneuverability. It is a better method in the treatment of adult clavicle AllmanⅠdisplaced fracture.

OBJECTIVE: To assess the trends in characteristics, treatments, and outcomes of acute myocardial infarction (AMI) patients in tertiary Chinese medicine (CM) hospitals in China between 2006 and 2013. METHODS: This retrospective study was based on two nationwide epidemiological surveys of AMI in tertiary CM hospitals during 2 years (2006 and 2013). Patients admitted to the hospital for AMI were enrolled. Hospital records were used as the data source. Case data were derived regarding baseline characteristics, treatments, and outcomes of patients to assess changes from 2006 to 2013. Logistic regression was used to analyze the relationship between prognosis, general influencing factors of disease, and various treatment measures. RESULTS: Totally 26 tertiary CM hospitals in 2006 and 29 tertiary CM hospitals in 2013 (18 were repetitive) were surveyed. A total of 2,311 patients with AMI were enrolled (1,094 cases in 2006 and 1,217 cases in 2013). From 2006 to 2013, the mean age did not significantly change, but the proportion of patients younger than 65 years increased. The prevalence of risk factors such as hypertension, diabetes, and hyperlipidemia also increased. Significant increases were observed in primary percutaneous coronary intervention [20.48% (2006) vs. 24.90% (2013)] and revascularization [36.11% (2006) vs. 52.42% (2013)]. In-hospital mortality decreased from 11.15% in 2006 to 10.60% in 2013. A mortality logistic regression analysis identified reperfusion therapy [odds ratio (OR), 0.222; 95% confidence interval (CI), 0.106-0.464], Chinese patent medicines (OR, 0.394; 95% CI, 0.213-0.727), and CM decoctions (OR, 0.196; 95% CI, 0.109-0.353) as protective factors. CONCLUSION Reperfusion and revascularization capabilities of tertiary CM hospitals have improved significantly, but in-hospital mortality has not significantly decreased. Efforts are needed to improve medical awareness of AMI and expand the use of CM to reduce in-hospital mortality in China.

OBJECTIVE: To investigate the types and proportion of gene mutations of thalassemia in Hakka people in Gannan Area of Jiangxi, and to provide some references for prevention and treatment of thalassemia major, genetic counseling and epidemiological studies. METHODS: 81 cases Hakka patients with severe thalassemia admitted treated in First Affiliated Hospital of Gannan Medical College from January 2009 to June 2019 were enrolled. The deletion type of α-thalassemia was detected by Gap-PCR. The point mutations of α-thalassemia and β-thalassemia were detected by PCR-RDB. The thalassemia gene was detected and analyzed in the patients with anemia, and the frequency of gene mutation was calculated. RESULTS: Among 81 Hakka patients with thalassemia major, 4 β-thalassemia (homozygote) genotypes were detected out, including: CD41-42（TTCT）(19 cases), β-IVS-II-654 (C→T) (9 cases), -28M (A→G) (1 case), CD17 (A→T) (1 case); 12 β-thalassemithalassemia (heterozygote) genotypes were detected out, including: CD41-42(-TTCT)/β-IVS-II-654(C→T) (15 cases, 29.41%), β-IVS-II-654(C→T)/β-28M(A→G) (13 cases，25.49%) ； CD41-42(-TTCT)/β-28M(A→G) (9 cases，17.65%); β-IVS-II-654(C→T) /CD27/28(+C) (3 cases， 5.88%) ； CD41-42(-TTCT)/CD27/28(+C)(3 case，5.88%)；β-28M(A→G)/CD17(A→T) (2 cases，3.92%)；CD41-42(-TTCT)/CD17(A→T), CD41-42(-TTCT)/Βe, β-IVS-II-654(C→T)/β-29、βCD17（A→T）/CD71-72(+a), βCD71-72/β-28M(A→G), β-28M(A→G) /β-IVS-II-654(C→T)(1 cases，1.96%). There were 3 cases of β homozygous thalassemia with α-thalassemia gene and 5 cases of β heterozygotes thalassemia with α-thalassemia gene. CONCLUSION The incidence rate of thalassemia in Hakka people in Gannan Area of Jiangxi is relatively high. The distribution of gene mutation types is as follows: the genotype of CD41-42 (-TTCT) is the main genotype of β-thalassemia (homozygous); the major genotypes of β- thalassemia (heterozygotes) are CD41-42 (-TTCT)/β-IVS-II-654 (C→T) and β-IVS-II-654 (C→T) /β-28M (A→G); CD41-42 (-TTCT) gene is dominant in β-complex α-thalassemia.

Intracerebral hemorrhage (ICH) refers to the primary non-traumatic parenchymal hemorrhage, which is one of the common cerebrovascular diseases, with a high incidence, rapid development, slow recovery and high disabling rate. After intracerebral hemorrhage, a series of pathological changes occur in the brain tissue, such as local hematoma and its space occupying effect, secondary cerebral edema, death of brain cells and destruction of blood-brain barrier, which may lead to brain injury and neurological defects, seriously affect the quality of life of patients, and even endanger the life. Therefore, it is great medical value to find effective therapeutic methods and drugs, explore the mechanisms and targets for improving neurological function, reduce sequelae and improve the quality of life of patients. According to the theory of traditional Chinese medicine (TCM), cerebral hemorrhage belongs to " abnormal flow of the blood" , which equals to blood stasis. In recent years, scholars conducted extensive research on drugs for promoting blood circulation to remove blood stasis with modern scientific methods, and made in-depth discussion for the mechanism, and found that therapies for activating blood and removing blood stasis, plays a key role in intervening a series of physiological and pathological changes after cerebral hemorrhage, with significant curative effects in removing hematoma, improving the microcirculation and reducing the mortality and morbidity. This article summarized drugs for promoting blood circulation to remove blood stasis (Notoginseng Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Hirudo), formulas (Buyang Huanwu Tang, Didangtang, Naoxueshu oral liquid, Tongqiao Huoxuetang) and compound injections (Danhong injection) for the treatment of cerebral hemorrhage targets, and discussed the experimental research progress TCM for promoting blood circulation to remove blood stasis in treatment of cerebral hemorrhage in terms of promoting hematoma absorption, reducing brain edema and apoptosis, promoting angiogenesis, inhibiting the inflammatory response, and promoting the repair and regeneration of nerve tissue in nearly five years, and summarized the therapeutic mechanism, so as to provide scientific basis for clinical application of the therapeutic methods for activating blood and removing stasis to treat cerebral hemorrhage and the modern scientific research.

Objetive To investigate the effect of Qingkailing injection on the expression of Toll-like receptor 4 (TLR4), gp91^phox and zonula occludens-1 (ZO-1) in cerebrovascular endothelial cells induced by hypoxia activation of microglias. Methods:BV2 microglia cells were divided into six groups. They were cultured in serum-free DMEM, while the Qingkailing groups of low, middle and high dosages were cultured with 0.0625%, 0.125% and 0.25% Qingkailing injection, respectively, and minocycline group with minocycline of 200 nmol/L. The groups other than control group underwent hypoxia for 24 hours and reoxygenation for 24 hours. Then, the medium of microglia was put into the medium of Balb/c endothelial cells for 24 hours. The cell viability of endothelial cells was measured with CCK-8, the concentration of nitric oxide (NO) was detected with colorimetry, and the experission of TLR4, gp91^phox and ZO-1 was detected with Western blotting. Results:Compared with the control group, the cell viability and the expression of ZO-1 decreased in the model group (P < 0.01), while the concentration of NO and the expression of TLR4 and gp91^phox increased (P < 0.05). Compared with the model group, the cell viability and the expression of ZO-1 increased in the Qingkailing groups and the minocycline group (P < 0.05), while the concentration of NO and the expression of TLR4 and gp91^phox decreased (P < 0.05). Conclusion:Qingkailing injection may enhance the survival and function of cerebrovascular endothelial cells by inhibiting the hypoxia activation of microglias, reducing the expression of TLR4 and gp91^phox, and increasing the expression of ZO-1.

Conclusion The NT- 3- HUMSCs joint SOCS3 gene silencing in the treatment of SD rat spinal cord injury can improve the motor function of SD rat spinal cord injury.

Objective To investigate the clinical effect of laparoscopic and open radical resection of hilar cholangiocarcinoma (Bismuth-I). Methods From January 2011 to January 2017, 34 patients (10 patients in the laparoscopic group and 24 patients in the open group) underwent radical resection of hilar cholangiocarcinoma. Their clinical data were analyzed retrospectively. Results All these patients underwent radical resection of hilar cholangiocarcinoma of type Bismuth-I successfully. The volume of blood loss was (179.50 ± 98.05) ml and duration of hospital stay was (11.80 ± 2.49) d of laparoscopic group which was lower than (261.25 ± 97.33) ml, (16.25 ± 3.35) d of open group (P < 0.05). The levels of Tbil of laparoscopic group at days after operation 1, 3, 5 d were (102.20 ± 45.49) mmol/L, (83.57 ± 30.66) mmol/L, (45.09 ± 18.41) mmol/L. The levels of Tbil of open group at days after operation 1, 3, 5 d were (148.17 ± 62.78) mmol/L, (121.60 ± 43.35) mmol/L, (80.59 ± 43.89) mmol/L. The difference was statistically significant (P < 0.05). And the laparoscopic group postoperative number of lymph nodes dissected (9.79 ± 3.05), postoperative complications (1 cases), positive margin (0 cases); and open group(9.30 ± 3.06), 3 cases, had no statistically significant differences were compared (P >0.05). Two groups of patients were followed up for 6~18 months. During the follow-up period, there was no recurrence or metastasis in the two groups. Conclusion Laparoscopic Bismuth-I radical resection of hilar bile duct carcinoma in lymph node dissection, postoperative complications, positive margin rate, prognosis and open type Bismuth-I hilar cholangiocarcinoma radical operation of similar effects, and more minimally invasive advantages. Therefore, laparoscopic radical resection for hilar cholangiocarcinoma of type Bismuth-I is safe and feasible.
