To evaluate long-term survival and clinical outcomes of patients with knee osteo-arthritis undergoing total knee arthroplasty (TKA) through long-term follow-up.

To analyze the occurrence of early complications after total hip arthroplasty (THA) in patients with systemic lupus erythematosus (SLE).

Objective: To explore the correlation between Diabetes Complication Severity Index(DCSI), C-reactive protein/albumin ratio(CAR) and death in patients with diabetic foot ulcer(DFU) and to clarify their predictive value for all-cause death in DFU patients. Methods: Retrospectively analyzed the clinical data of 354 DFU patients who were treated in the Endocrinology Department of the First Affiliated Hospital of Anhui Medical University from July 2019 to December 2022. Based on survival status during follow-up, patients were divided into a survival group(n=268) and a death group(n=86). Univariate and multivariate Cox regression analyses were used to identify risk factors for all-cause death in DFU patients. Receiver operating characteristic(ROC) curves were plotted to evaluate the predictive value of DCSI, CAR, and their combination for all-cause death in DFU patients. Kaplan-Meier curves were used to explore the impact of different DCSI and CAR levels on survival in DFU patients. Results: Univariate Cox regression analysis showed that older age, history of hypertension, higher Wagner classification levels, and elevated levels of CRP, Scr, FDP, DCSI score, and CAR were associated with a higher risk of death in DFU patients(P<0.05). Higher levels of HGB, HCT, ALB, or eGFR were associated with a lower risk of death. Patients receiving combined insulin and oral hypoglycemic medication had a lower risk of death compared to those receiving only insulin therapy(P<0.05). Multivariate Cox regression analysis indicated that older age, higher levels of Scr, DCSI, and CAR were independent risk factors for all-cause death in DFU patients, while higher levels of ALB and combined insulin and oral hypoglycemic therapy were protective factors. ROC curve analysis showed that the AUC values for DCSI, CAR, and their combination were 0.652, 0.633, and 0.686, respectively. Kaplan-Meier curve analysis revealed that patients with high DCSI scores(≥4.5) had a lower survival rate compared to those with lower DCSI scores(<4.5). Similarly, patients with high CAR levels(≥0.124) had a lower survival rate compared to those with lower CAR levels(<0.124). Conclusion High levels of DCSI and CAR are independent risk factors for all-cause death in DFU patients. DCSI, CAR, and their combination have predictive value for all-cause mortality in DFU patients.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Objective:To analyze the epidemiological characteristics of human respiratory syncytial virus (HRSV) in patients with acute respiratory infection (ARIs) in sentinel hospitals of the Hubei influenza surveillance network from 2016 to 2023.Methods:ARIs samples [including influenza-like cases (ILI) and severe acute respiratory infection (SARI)] were collected from influenza surveillance sentinel hospitals in Hubei Province from 2016 to 2023, and case information was collected. HRSV virus nucleic acid typing was performed by fluorescence quantitative PCR method, and the data were collated, plotted and analyzed.Results:From 2016 to 2023, 12 779 cases of ILI and 9 166 cases of SARI were collected. The positive rate of HRSV was the highest in<5 years of age group [15.77% (168/1 065)], among which the positive rate was the highest in 2 to 5 years of age group of ILI cases [13.60% (31/228)], and the positive rate was the highest in 0 to 2 years of age group of SARI cases [25.97% (60/231)] (all P values<0.001). The positive rate of HRSV in SARI cases was 2.31%-25.97%, higher than that in ILI cases (0-13.60%) ( P=0.016). HRSV was prevalent in autumn and winter from 2016 to 2020 and in spring in 2023. Alternating epidemics of HRSV virus type A and B in Hubei Province from 2016 to 2023 (dominant epidemics of type B in 2016 and 2020; dominant epidemics of type A in 2017-2019 and 2023). Conclusion:SARI and ILI patients under five years old are the main infection groups of HRSV. The seasonal prevalence characteristics of HRSV in Hubei Province from 2016 to 2023 shift from autumn and winter to spring.

In this report,we described a case of a clinical practice,in which the clinical pharmacists was involved in the treatment of a soft tissue sarcoma patient,who was diagnosed with mental disorders induced by regorafenib.The patient was complicated with hypoproteinemia,hepatic insufficiency,leukoencephalopathy and other diseases.Before the treatment,the patient's mental was normal.After continuous administration of regorafenib(40 mg,po,qd)for 5 days,the patient has a sudden loss of consciousness.Clinical pharmacists excluded the possibility of mental disorders caused by tumor brain metastases,exacerbation of leucoencephalopathy or hepatic encephalopathy and the drugs used together.They determined that mental disorders were likely to be related to the use of regorafenib through the association evaluation of adverse reactions.It was considered to be an adverse reaction induced by regorafenib.Therefore,regorafenib treatment was temporarily suspended and symptomatic treatment was given.After 5 days,the patient's mental state improved.In addition,clinical pharmacists monitored the patient for symptomatic treatment,and provided appropriate antitumor drug treatment recommendations based on evidence-based evidence.This case suggests that the clinical use of regorafenib should be vigilant against mental disorders adverse reactions,do a good job of pharmaceutical care,and timely drug analysis and symptomatic treatment after adverse reactions.

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 identify the differentially expressed proteins that caused hippocampal damage after liver ischemia-reperfusion (I/R) in rats.Methods:Eighteen clean-grade healthy juvenile male Sprague-Dawley rats, aged 2 weeks, weighing 20-30 g, were divided into 2 groups ( n=9 each) using a random number table method: sham operation group (S group) and liver I/R group (IR group). A rat model of liver I/R injury was prepared by restoring perfusion after 1 h of liver ischemia. The rats were sacrificed after being anesthetized at day 3 of reperfusion, and the hippocampal tissue was isolated and analyzed to obtain gene expression profiles. Differentially expressed genes were identified using the R software, and further protein interaction networks were constructed through Cytoscape and Kyoto Encyclopedia Genes and Genomes pathway analysis to determine the differentially expressed proteins. Quantitative real-time polymerase chain reaction and Western blot were used for validation. Results:A total of 45 differentially expressed proteins were identified by the proteomic analysis of hippocampal tissues, including 36 significantly up-regulated proteins and 9 significantly down-regulated proteins. The proteins with significant expression related to injury were identified from the PPI network complex using the CytoHubBA plug-in cystscape: Ras-related C3 botulinum toxin substrate (RAC2), HRAS, phosphatidylinositol-3-kinase inhibitor phosphatase and tensin homologue (PTEN), and N-methyl-D-aspartate ionotropic glutamate receptor 2b (GRIN2b). The results of quantitative real-time polymerase chain reaction and Western blot showed that the expression of RAC2, HRAS, PTEN, and GRIN2b in the hippocampal tissue was significantly up-regulated in IR group compared with S group ( P<0.05). The results of Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that differentially expressed proteins were significantly enriched in the expression of PD-L1 and its checkpoint pathway, long-term potentiation, and regulation of the Wnt signaling pathway in cancer. Conclusions:The mechanism by which liver I/R induces hippocampal injury may be related to the up-regulation of the expression of RAC2, HRAS, PTEN and GRIN2b in rats.

Objective:To explore the effect of esketamine on inflammatory cytokines and myocardial injury markers in children undergoing living-donor liver transplantation (LT).Methods:Considering the inclusion criteria, 50 children with biliary atresia were selected for living donor LT. They were equally randomized into two groups of control (C) and esketamine (E) (25 cases each). Esketamine 0.5 mg/kg was administered to group E during induction and continued at a dose of 0.5 mg·kg –1·h -1 after an induction of anesthesia. Group C provided the same dose of 0.9% sodium chloride injection during induction and then continued to pumping until the end of the procedure. Basic profiles of two groups were recorded. Hemodynamic parameters, such as heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP), were monitored at 5 min of anesthesia induction (T 0), 30 min of anhepatic phase (T 1), immediately after repercussion (T 2), 30 min of neohepatic phase (T 3) and end of surgery (T 4) in both groups. Central venous blood samples were collected at T 0, T 1, T 3 and T 4. Serum levels of cardiac troponin I (cTnI), creatine kinase isoenzyme-MB (CK-MB) ,tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) were measured. The incidence of adverse cardiac events, postoperative mechanical ventilation time, ICU stay and hospitalization length were compared. Results:As compared with T 0, mean arterial pressure (MAP) at T 2 declined markedly in group E [(48.6±12.7) mmHg (1 mmHg=0.133 kPa) vs (55.6±10.7) mmHg, P<0.001] and C [(39.3±8.0) mmHg vs (53.2±9.4) mmHg, P<0.001 ] ;As compared with T 0, the TNF-α and IL-6 spiked at T 3 in group C [169.0 (207.1) ng/L vs 43.8 (26.4) ng/L, (132.63±51.75) ng/L vs (51.79±17.83) ng/L, P<0.001] and E [78.5 (138.8) ng/L vs 43.8 (26.4) ng/L, (87.44±32.17) ng/L vs (51.79±17.83) ng/L, P<0.001 ] ; In group C, the concentration of myocardial injury markers CK-MB and cTnI rose at T 3/T 4 compared with T 0[T 3 vs T 0: 5.7 (5.4) μg/L vs 4.0 (3.5) μg/L, 0.09 (0.08) μg/L vs 0.02 (0.02) μg/L; T 4 vs T 0: 5.3 (5.0) μg/L vs 4.0 (3.5) μg/L, 0.07 (0.08) μg/L vs 0.02 (0.02) μg/L, P<0.001 ]. In group E, the levels of CK-MB and cTnI were higher at T 3/T 4 than those at T 0[T 3 vs T 0: 7.0 (5.0) μg/L vs 4.6 (2.1) μg/L, 0.06 (0.09) μg/L vs 0.03 (0.04) μg/L; T 4 vs T 0: 5.4 (4.9) μg/L vs 4.6 (2.1) μg/L, 0.03 (0.06) μg/L vs 0.03 (0.04) μg/L; P<0.001].

Compared with group C, TNF-α and IL-6 decreased in E at T 3/T 4[T 3: 78.5 (138.8) ng/L vs 169.0 (207.1) ng/L, P=0.010; (87.44±32.17) ng/L vs (132.63±51.75) ng/L, P=0.017. T 4: 62.3 (118.3) ng/L vs 141.3 (129.2) ng/L, P=0.001; (74.34±26.38) ng/L vs (100.59±30.40) ng/L, P=0.002]. Compared with group C, cTnI decreased in E at T 3/T 4[0.06 (0.09) μg/L vs 0.09 (0.08) μg/L, P=0.014; 0.03 (0.06) μg/L vs 0.07 (0.08) μg/L, P=0.003]. Compared with group C, the mechanical ventilation time in group E decreased [195 (120) min vs 315 (239) min, P<0.001]. Compared with group C, the incidence of severe hypotension [16%(4/25) vs 48% (12/25), P=0.015 ], bradycardia [12% (3/25) vs 36 % (9/25), P=0.047 ], myocardial ischemia [4 % (1 /25) vs 24 % (6/25), P=0.042 ] and premature ventricular contractions [0 vs 4 %(1/25), P=0.312 ] decreased in group E. Conclusion:Intraoperative dosing of esketamine may suppress inflammatory reactions and alleviate perioperative myocardial injury in children undergoing living-donor LT.
