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 understand the characteristics and trend of the premature death rate of 4 major chronic diseases in Ji'nan from 2015 to 2020. Methods: The death cause surveillance data and population data during 2015-2020 in Ji'nan were collected, and abbreviated life table, Joinpoint regression analysis and other methods were used to analyze the characteristics and change trends of the premature death rates of 4 major chronic diseases. Results: The crude mortality rate and age standardized mortality rate changes for the 4 major chronic diseases from 2015 to 2020 range from 568.65/100 000 to 604.06/100 000 and 366.77/100 000 to 432.48/100 000, respectively. The annual premature death rate of 4 major chronic diseases declined by 3.33% averagely from 2015 to 2020 (95%CI: -6.25%--0.32%), which might be explained by the declines of the premature death rates of cardiovascular and cerebrovascular diseases [average annual percentage change (AAPC)=-3.23%, 95%CI: -6.32%--0.05%] and cancer (AAPC=-3.58%,95%CI:-6.83%--0.21%). The average decline rate in women (AAPC=-4.19%,95%CI:-7.56%- -0.70%) was higher than that in men (AAPC=-2.92%,95%CI: -5.65%--0.11%). Conclusions: The premature death rate of 4 major chronic diseases showed a downward trend in Ji'nan from 2015 to 2020. Men should be considered as a key population in the prevention and control of 4 major chronic diseases, and attention should also be paid to the non-significant declines in the premature death rates of chronic respiratory diseases and diabetes.

OBJECTIVE: To evaluate the effectiveness of different screening strategies for type 2 diabetes to prevent cardiovascular disease in a community-based Chinese population from economically developed areas based on the Chinese electronic health records research in Yinzhou (CHERRY) study. METHODS: A Markov model was used to simulate different systematic diabetes screening strategies, including: (1) screening among Chinese adults aged 40-70 years recommended by the 2020 Chinese Guideline for the prevention and Treatment of Type 2 Diabetes (Strategy 1); (2) screening among Chinese adults aged 35 to 70 years recommended by the 2022 American Diabetes Association Standard of Medical Care in Diabetes (Strategy 2); and (3) screening among Chinese adults aged 35-70 years with overweight or obesity recommended by the 2021 United States Preventive Services Task Force Recommendation Statement on Screening for Prediabetes and Type 2 Diabetes (Strategy 3). According to the guidelines, individuals who were screened positively (fasting plasma glucose ≥ 7.0 mmol/L) would be introduced to intensive glycemic targets management (glycated hemoglobin < 7.0%).The Markov model simulated different screening scenarios for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Number of cardiovascular disease events or deaths could be prevented and number needed to screen (NNS) were calculated to compare the effectiveness of the different strategies. One-way sensitivity analysis on the sensitivity of screening methods and probabilistic sensitivity analysis on uncertainties of diabetes incidence, the sensitivity of screening methods, and intensive glycemic management effects were conducted. RESULTS: Totally 289 245 Chinese adults aged 35-70 years without cardiovascular diseases or diagnosed diabetes at baseline were enrolled. In terms of the number of cardiovascular disease events could be prevented, Strategy 1 for systematic diabetes screening among the adults aged 35-70 years was 222 (95%UI: 180-264), Strategy 2 for systematic diabetes screening among the adults aged 40-70 years was 227 (95%UI: 185-271), and Strategy 3 for systematic diabetes screening among the adults aged 35-70 years with obesity or overweight (body mass index ≥ 24 kg/m²) was 131 (95%UI: 98-164), compared with opportunistic screening. NNS per cardiovascular disease event for the strategies 1, 2 and 3 were 1 184 (95%UI: 994-1 456), 1 274 (95%UI: 1 067-1 564) and 814 (95%UI: 649-1 091), respectively. Compared with Strategy 1, NNS per cardiovascular disease event for Strategy 2 increased by 90 (95%UI: -197-381) with similar effectiveness of cardiovascular prevention; however, NNS per cardiovascular disease event for Strategy 3 was reduced by 460 (95%UI: 185-724) in contrast to the Strategy 2, suggesting that the Strategy 3 was more efficient. The results were consistent in multiple sensitivity analyses. CONCLUSION Systematic screening for diabetes based on the latest guidelines in economically developed areas of China can reduce cardiovascular events and deaths. However, merely lowering the starting age of screening from 40 to 35 years seems ineffective for preventing cardiovascular disease, while screening strategy for Chinese adults aged 35-70 years with overweight or obesity is recommended to improve efficiency.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

Objective:To investigate the clinical efficacy of ex vivo liver resection and autotransplantation (ELRA) for liver complex space-occupying lesions.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 50 patients with liver complex space-occupying lesions who underwent ELRA in the First Hospital Affiliated to Army Medical University between June 2009 and May 2017 were collected. There were 36 males and 14 females, aged from 13 to 69 years, with a median age of 51 years. All patients underwent ELRA. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination or telephone interview. Patients were followed up according to the individual follow-up plan in the first 6 months after discharge, and then once every 3 to 6 months to detect tumor recurrence and survival up to May 2019. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M (range). Count data were expressed as absolute numbers or percentages. The Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-rank test was used for survival analysis. Results:(1) Surgical situations: all the 50 patients underwent ELRA successfully, and postoperative pathological examination showed the R 0 resection rate was 100%(50/50). The operation time of the 50 patients were (630±186)minutes, of which 9 patients with liver benign occupation had the operation time of (684±168)minutes and 41 patients with liver malignant tumor had the operation time of (618±190)minutes. The operation time of temporary reconstruction of inferior vena cava and portacaval shunt, time of anhepatic phase, volume of intraoperative blood loss of the 50 patients were (35±9)minutes, (256±71)minutes, 2 000 mL(range, 400-10 000 mL), respectively. The remnant liver mass to standard liver mass ratio of the 50 patients was 65%±16%, of which 9 patients with liver benign occupation had the remnant liver mass to standard liver mass ratio of 63%±14% and 41 patients with liver malignant tumor had the remnant liver mass to standard liver mass ratio of 65%±17%. Of the 50 patients, 35 had vascular invasion (7 cases with liver benign occupation, 28 cases with liver malignant tumor), of which 24 (6 cases with liver benign occupation, 18 cases with liver malignant tumor) underwent in vitro vascular reconstruction, 12 (5 cases with liver benign occupation, 7 cases with liver malignant tumor) had bile duct invasion and underwent choledochojejunostomy due to the inability of the common bile duct to anastomose the ends. Two cases with liver metastasis of gastric cancer, one case with liver metastasis of colon cancer and one case with liver metastasis of pancreatic cancer underwent radical gastrectomy, radical resection of colon cancer, and pancreaticoduodenectomy, respectively. (2) Postoperative situations: the duration of postoperative hospital stay of the 50 patients were 25 days (range, 11-169 days). Of the 50 patients, 12 had pleural effusion who were treated with pleural puncture drainage, 10 had bile leakage who were treated with abdominal puncture drainage, 3 had bile duct anastomotic leakage who were treated with endoscopic nasobiliary drainage or biliary stent implantation, 6 underwent reoperation among which 4 underwent exploratory laparotomy due to abdominal hemorrhage, 1 underwent portal vein reconstruction due to abdominal hemorrhage combined with portal vein thrombosis, and 1 underwent salvage liver transplantation due to liver failure. Nine of the 50 patients died within 90 days after surgery, all of whom had liver malignant tumor. Among them, 3 died of multi-organ dysfunction syndrome caused by severe infection, 3 died of acute liver failure, 2 died of abdominal hemorrhage and 1 died pulmonary embolism. (3) Follow-up: all the 50 patients were followed up for 1 to 119 months. The overall survival time, 1-, 3-, 5-year overall and tumor-free survival rates of the 50 patients after operation were 17 months (range, 1-119 months), 68.0%, 45.9%, 41.1% and 41.9%, 33.4%, 30.8%, respectively. The overall survival time, 1-, 3-, 5-year overall and tumor-free survival rates of the 9 patients who with liver benign occupation after operation were 68 months (range, 10-114 months), 88.9%, 88.9%, 88.9% and 88.9%, 88.9%, 88.9%, respectively. The overall survival time, 1-, 3-, 5-year overall and tumor-free survival rates of the 41 patients who with liver malignant tumor after operation were 15 months (range, 1-119 months), 63.4%, 36.6%, 31.0% and 31.5%, 21.0%, 18.0%, respectively. There were significant differences in the overall and tumor-free survival rates between patients who with liver benign occupation and patients who with liver malignant tumor ( χ2=7.626, 11.766, P<0.05). Conclusions:ELRA can be applied in the treatment of liver complex space-occupying lesions. The selection criteria of patients with liver malignant tumor should be more rigorous to reduce perioperative mortality.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Objective:To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China.Methods:This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed.Results:Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn′t be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%.Conclusions:More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

OBJECTIVE: The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire (FFQ) among Chinese children aged 12-17 years. METHODS: A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls (24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children (N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients (ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. RESULTS: For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman's correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from -0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. CONCLUSION The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

To evaluate the effectiveness of minimally invasive bridging for the lateral malleolar fractures in the open comminuted ankle fractures with dislocation. Methods The clinical data of 24 patients [19 males and 5 females aged 40 to 65 years,mean(47.5±8.6)years] with open comminuted ankle fractures with dislocation who were treated in the Second Hospital of Tangshan from September 2015 to June 2017 were retrospectively analyzed.All patients were treated with minimally invasive bridging for the lateral malleolar fractures.The ankle function after treatment was assessed with the Olerud Molander Ankle(OMA)score. Results All the 24 patients were followed up from 12-26 months [mean:(14.5±2.6)months].Good fracture union was achieved in all patients after 2 - 5 months(mean:3 months).No deep infection,skin necrosis,or bone nonunion occurred after 12 months of follow-up.Only one patient suffered from partial skin necrosis at lateral malleolus,which was cured after changing wound dressings.The OMA score was 93.5(range:85-100)after 12 months(excellent in 19 cases and good in 5 cases). Conclusions Minimally invasive bridging for the lateral malleolar fractures is effective in treating the open comminuted ankle fractures with dislocation.It can obtain good reduction and fixation,reduce complications,and achieve high union rate.
