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 explore the relationship between relapse tendency and childhood maltreatment in methamphetamine-dependent youths,and the role of impulsivity and quality of life in the relationship.Methods:To-tally 287 methamphetamine-dependent youths(160 females,127 males)were selected in compulsory drug rehabili-tation centers.The Relapse Tendency Questionnaire(RTQ),Childhood Trauma Questionnaire-Short Form(CTQ-SF),Barrett Impulsivity Scale(BIS-11)and Quality of Life for Drug Addicts(QOL-DA)for Drug Addicts were used to conduct the survey.SPSS macro program PROCESS was used to test the mediating role.Results:The BIS-11 total scores acted as a partial mediator between the total scores of CTQ-SF and RTQ,with an effect value of 0.03(95％CI:0.01-0.05),the QOL-DA total scores acted as a full mediator between the total scores of CTQ-SF and RTQ,with an effect value of 0.05(95％CI:0.02-0.08),and the scores of BIS-11 and QOL-DA acted as chain mediators between total scores of CTQ-SF and RTQ,with an effect value of 0.01(95％CI:0.00-0.03).Conclusion:Childhood maltreatment,impulsivity,and quality of life may be associated with relapse tendencies in methamphetamine-dependent youths.

OBJECTIVE To explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.

A total of 18 batches of Zhuru Decoction samples were prepared. Chromatographic fingerprints were established for Zhuru Decoction and single decoction pieces, the content of which was then determined. The extraction rate ranges, content, and transfer rate ranges of puerarin, liquiritin, and glycyrrhizic acid, together with the common peaks and the similarity range of the fingerprints, were determined to clarify key quality attributes of Zhuru Decoction. The 18 batches of Zhuru Decoction samples had 25 common peaks and the fingerprint similarity higher than 0.95. Puerariae Lobatae Radix, Glycyrrhizae Radix et Rhizoma, and Zingiberis Rhizoma Recens had 21, 3, and 1 characteristic peaks, respectively. The 18 batches of samples showed the extraction rates within the range of 18.45%-25.29%. Puerarin had the content of 2.20%-3.07% and the transfer rate of 38.5%-45.9%; liquiritin had the content of 0.24%-0.85% and the transfer rate of 15.9%-37.5%; glycyrrhizic acid had the content of 0.39%-1.87% and the transfer rate of 16.2%-32.8%.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.

Klotho is highly expressed in the kidney, while soluble Klotho is detectable in the blood, urine, and cerebrospinal fluid, and has multiple hormone-like functions. The role of Klotho in kidney injury has attracted more and more attentions from researchers. Emerging evidence revealed that the transient deficiency of Klotho is an early event of acute kidney injury (AKI), whereas, in chronic kidney disease, this deficiency is sustained not only in the kidney, but also in other organ systems. Therefore, Klotho could be a potential biomarker for early diagnosis of AKI, as well as for its progression to chronic kidney disease. Moreover, Klotho might have therapeutic value to renal injury. Nevertheless, there are only few studies on the involvement of Klotho in post AKI repair. This review focused on the role of Klotho in not only kidney injury, but also its repair, in particular the relationship between Klotho and cell fate (autophagy/apoptosis/necrosis), repair/regeneration, Wnt/β-catenin and erythropoietin receptor, one of the Klotho effectors.

OBJECTIVETo summarize the treatment status of gastric gastrointestinal stromal tumor (GIST) in Shandong province,by analyzing the clinicopathological features and prognostic factors.

METHODSClinicopathological and follow-up data of 1 165 patients with gastric GIST between January 2000 and December 2013 from 23 tertiary referral hospitals in Shandong Province were collected to establish a database. The risk stratification of all cases was performed according to the National Institutes of Health(NIH) criteria proposed in 2008. Kaplan-Meier method was used to calculate the survival rate. Log-rank test and Cox regression model were used for univariate and multivariate prognostic analyses.

RESULTSAmong 1 165 cases of gastric GIST, 557 were male and 608 were female. The median age of onset was 60 (range 15-89) years. Primary tumors were located in the gastric fundus and cardia in 623 cases(53.5%), gastric body in 346 cases(29.7%), gastric antrum in 196 cases(16.8%). All the cases underwent resection of tumors, including endoscopic resection (n=106), local resection (n=589), subtotal gastrectomy(n=399), and total gastrectomy(n=72). Based on the NIH risk stratification, there were 256 cases (22.0%) at very low risk, 435 (37.3%) at low risk, 251 cases (21.5%) at intermediate risk, and 223 cases (19.1%) at high risk. A total of 1 116 cases(95.8%) were followed up and the median follow-up period was 40 (range, 1-60) months. During the period, 337 patients relapsed and the median time to recurrence was 34 (range 1-60) months. The 1-, 3-, and 5-year survival rates were 98.6%, 86.1% and 73.4%, respectively. The 5-year survival rates of patients at very low, low, intermediate, and high risk were 93.1%, 85.8%, 63.0% and 42.3% respectively, with a statistically significant difference (P=0.000). Multivariate analysis showed that primary tumor site (RR=0.580, 95%CI:0.402-0.835), tumor size (RR=0.450, 95%CI:0.266-0.760), intraoperative tumor rupture(RR=0.557, 95%CI:0.336-0.924), risk classification (RR=0.309, 95%CI:0.164-0.580) and the use of imatinib after surgery (RR=1.993, 95%CI:1.350-2.922) were independent prognostic factors.

CONCLUSIONSThe choice of surgical procedure for gastric GIST patients should be based on tumor size. All the routine procedures including endoscopic resection, local excision, subtotal gastrectomy and total gastrectomy can obtain satisfactory curative outcomes. NIH classification has a high value for the prediction of prognosis. Primary tumor site, tumor size, intraoperative tumor rupture, risk stratification and postoperative use of imatinib are independent prognostic factors in gastric GIST patients.
