Objective: To improve the efficiency and standardization of preoperative anemia diagnosis and treatment by establishing a systematic intelligent management platform for preoperative anemia. Methods: A multidisciplinary collaborative model was adopted to develop a preoperative anemia management system that integrates intelligent early warning, standardized treatment pathways, and quality control. The system utilizes natural language processing technology to automatically capture laboratory data and establish evidence-based medical decision support functions. A pre-post study design was employed to compare changes in preoperative anemia screening rates, preoperative anemia intervention rates, reasonable use of iron supplements, and perioperative red blood cell transfusion rates before and after system implementation. Results: After system implementation, the standardization of anemia diagnosis and treatment significantly improved: 1) Screening effectiveness: The anemia screening rate increased to 50.00% (an increase of 27.24%); 2) Intervention effectiveness: The anemia treatment rate rose to 56.30% (an increase of 14.02%); 3) Treatment standardization: The reasonable use rate of iron supplements increased to 55.33% (an increase of 21.02%); the red blood cell transfusion rate decreased to 18.29% (a decrease of 4.07%), and the amount of red blood cell transfusions was reduced by 291 units. Conclusion: This system achieves full-process management of preoperative anemia through information technology, significantly enhancing the standardization of diagnosis and treatment as well as intervention effectiveness, providing an effective solution for perioperative anemia management.

Objective This paper investigates the effect of a multi-physical field fusion intervention based on transcranial direct current stimulation(tDCS),transcranial magnetic stimulation(TMS)and music on mental fatigue.Methods After fatigue induction,10 subjects received blank group stimulation,music group stimulation and tDCS-TMS-Music stimulation,respectively.tDCS stimulation sites were located in the bilateral frontal regions of the subjects,and TMS stimulation sites were located in the bilateral occipital regions of the hindbrain.Heart rate variability and reaction performance were measured before and after each intervention to determine the elimination effect of different intervention programs on mental fatigue.Results Compared with the control group,the tDCS-TMS-Music group showed significantly greater improvements in subjective mental workload,response performance,and heart rate variability.Conclusion The results of this study support that tDCS-TMS-Music can effectively alleviate mental fatigue induced by long-term cognitive performance tasks,and the intervention effect is better than music intervention and resting-state relief at the same time.

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.

Patients with type 2 diabetes mellitus (T2DM) typically have a higher risk of cardiovascular diseases, including coronary artery disease (CAD). Currently, the gold standard for diagnosing the severity of coronary artery lesions in T2DM patients is coronary angiography (CAG). This retrospective analysis reviewed data from T2DM patients who underwent CAG at Hengshui People′s Hospital between May 2020 and July 2022. Utilizing multivariate logistic regression analysis, factors associated with the severity of coronary artery stenosis in T2DM patients were identified. Based on these findings, a predictive model was developed to evaluate CAD severity in T2DM patients, incorporating smoking history, elevated triglyceride-glucose (TyG) index, and elevated monocyte to high-density lipoprotein cholesterol ratio (MHR). The combination of the TyG index and MHR model provides insights into coronary artery stenosis severity in T2DM patients, potentially reducing unnecessary invasive CAG procedures.

The deubiquitinases (DUBs), as the crucial peptidohydrolases in the ubiquitin system, can reverse and strictly regulate ubiquitination and play key roles in various biological processes, including the regulation of protein stability, cell signal transduction. Ubiquitin-specific protease 28 (USP28) involves multiple cancer-related signaling pathways by enhancing the stability of various cancer-related proteins, and is closely associated with the progression of colorectal, breast cancer, lung carcinomas, and pancreatic cancer. USP28 has been considered as a promising drug target in anticancer therapy, and the development of USP28 inhibitors has made some progress. In this article, we review the structure of USP28 and its interaction with substrates, discuss the research progress of USP28 in cancers and summarize the development of USP28 inhibitors.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.

Objective:To explore the clinical characteristics of dislocation after resection and reconstruction of tumors involving pelvic area II, and to try to propose intraoperative and postoperative techniques to prevent its occurrence.Methods:From March 2011 to March 2021, 122 patients with resection and reconstruction involving pelvic area II were retrospectively analyzed. Among them, 17 had postoperative dislocation, 32 had pelvic area II, and 31 had pelvic area I+II. There were 40 cases in the pelvic area II+III, and 19 cases in the pelvic area I+II+III. There were 49 female patients and 73 male patients; the mean age was 47 years (9-73 years). The Musculoskeletal Tumor Society (MSTS) score of lower extremity patients after reduction was evaluated, and the clinical characteristics of dislocation, such as dislocation direction, dislocation time and reduction method, were counted and analyzed, and feasible prevention measures were analyzed based on the imaging characteristics after resection and reconstruction. dislocation method.Results:Among the 122 patients, there were 17 cases of dislocation, and the dislocation rate was 13.7%. Among them, 12 cases were anterior dislocation, accounting for 70.6% of anterior dislocation; 5 cases were posterior dislocation, and the proportion of posterior dislocation was 29.4%, difference (χ 2=4.52, P=0.033). There were 12 cases of dislocation within 3 months after operation, accounting for 70.6%; 1 case of dislocation occurred in 5 months after operation, and the other 4 cases of dislocation occurred for more than one year. The MSTS score of the dislocation patients after reduction was 56.1±15.6% (20%-80%). Combined with postoperative imaging examinations, the feasible methods for preventing dislocation include: The anteversion angle of the acetabular cup can be appropriately reduced (0°-10°); The acetabular cup can be appropriately shifted to the rear of the rotation center; Appropriately reducing the anteversion angle of the femoral neck prosthesis, the combination of the three can reduce the occurrence of femoral-acetabular prosthesis impingement; at the same time, the affected limb is controlled in a neutral position with strict nail shoes after surgery to avoid the occurrence of external rotation. Conclusion:The dislocation after tumor resection and reconstruction in pelvic area II is mostly anterior dislocation. Postoperative CT scan of the pelvis shows that the space between the neck of the femoral stem prosthesis and the lower edge of the acetabulum is small, which is prone to impingement. If the anteversion angle of the acetabular cup is appropriately reduced, the acetabular prosthesis is appropriately displaced posteriorly, and the anteversion angle of the femoral neck is reduced by 5°, the possibility of femoral-acetabular impingement can be reduced, thereby reducing the risk of postoperative dislocation.

Objective    To investigate the feasibility of magnamosis rings designed based on magnetic compression technique in esophageal anastomosis reconstruction. Methods    According to the anatomical characteristics of esophagus in SD rats, the esophageal magnamosis rings were designed. SD rats were used as animal models (n=10, 5 males and 5 females) to complete the magnetic anastomosis reconstruction of the cervical esophagus using magnamosis rings, and the operation time, animal survival, postoperative complications, magnetic rings excretion time were recorded. Two weeks after operation, the rats were killed, and the esophageal anastomotic specimens were obtained. The blasting pressure of the anastomotic site was measured and the formation of the anastomotic site was observed with naked eyes. Results    Esophageal magnamosis was successfully performed in 10 SD rats, and the median operation time was 11 (8-13) min. All rats survived without anastomotic leakage, anastomotic stenosis, or magnetic rings incarceration. The magnetic rings were discharged after 8 (5-10) days and the burst pressure was higher than 300 mm Hg. Visual observation showed that the anastomotic muscle healed well and the mucosa was smooth. Conclusion    The magnetic compression technique  can be used for anastomosis reconstruction of esophagus, which has the advantages of simple operation and reliable anastomosis effect, and has clinical application prospect.

Objective: To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases. Methods: A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. Results: The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. Conclusion The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.

Objective:To compare the clinical effect of perforator flap of proper palmar digital and hallex fibular flap in repair of soft tissue defect of fingers.Methods:A total of 52 patients with finger soft tissue injury were reviewed from January, 2017 to January, 2019. Twenty-seven patients were repaired by perforator flap of proper palmar digital artery, and 25 by hallex fibular flaps. Both groups of patients had only soft tissue defects without phalangeal fracture. Postoperative follow-up were conducted by phone, WeChat and visit of outpatient clinic. The recovery of finger sensory function was evaluated according to the Trial Standard for Replantation Evaluation of Severed Digit by the Hand Surgery Society of Chinese Medical Association. The flaps were evaluated according to the shape, patient satisfaction and finger function and classified in excellent, good, fair and poor. Data of the 2 groups of patients were collected and statistically analysed by SPSS 22.0. P<0.05 was statistically significant. Results:Both groups entered follow-up for 12-16 months. All flaps in both groups survived. There was statistically significant difference of TPD between the 2 groups[TPD were 4-7(5.3±1.2) mm and 6-10(8.4±1.7)mm, respectively]( t=7.642, P=0.000). According to the Evaluation Criteria of the Hand Surgery Society of the Chinese Medical Association. In the group repaired by perforator flap of proper palmar digital artery, 17 fingers were excellent, 6 good, and 4 fair, with a 85.1% of excellent and good rate. In the group repaired by hallex fibular flap, 8 fingers were excellent, 5 good, 9 fair, and 3 poor, with a 52.0% of excellent and good rate. The difference between 2 groups was statistically significant ( t=6.710, P=0.009). There was a 3.7% incidence of complications in the group repaired by perforator flap of proper palmar digital artery, and 25.9% in the group repaired by hallex fibular flap. The difference between the 2 groups was statistically significant( t=4.167, P=0.032), and there was a higher incidence of complications in the group repaired by hallex fibular flap. Conclusion:The perforator flap of proper palmar digital artery and the hallex fibular flap are good choices in the repair of finger soft tissue defect. However, the postoperative complication of the hallux fibular flap is relatively high. Therefore, it is necessary to make a decision in the choice of flap according to the actual situation in clinical work.
