[Objective] To compare the efficacy and safety of deglycerolized red blood cells (DRBC) and suspended red blood cells (SRBC) based on the propensity score matching (PSM) method, so as to provide evidence for the rational use of DRBC resources in clinical practice. [Methods] A total of 89 patients who received DRBC transfusion and 2 916 patients who received SRBC transfusion in our hospital from January 2023 to September 2024 were included. A 1∶1 nearest neighbor PSM was used to balance covariates such as gender, age, and body mass index (BMI). The changes of hemoglobin (Hb), red blood cell (RBC) count, hematocrit (HCT), and inflammatory markers such as white blood cell (WBC) count, neutrophil (NE) count, C-reactive protein (CRP), and Interleukin-6(IL-6) in the last 72 hours after transfusion were analyzed by SPSS 26.0 and R software to evaluate clinical efficacy and transfusion safety. [Results] The baseline of the two groups was balanced after PSM (P>0.05). There was no significant difference in the total effective rate between the DRBC group (80.9%) and the SRBC group (86.5%) (P>0.05). In the SRBC group, WBC (×10 /L) increased from 9.634±6.742 to 10.147±6.835, CRP (mg/dL) increased from 5.468±4.647 to 6.174±6.114, and IL-6(pg/mL) decreased from 213.733±587.191 to 157.255±552.626. In the DRBC group, WBC (×10 /L) decreased from 11.123±7.880 to 11.011±8.549, CRP (mg/dL) decreased from 5.729±4.761 to 5.326±4.466, and IL-6(pg/mL) decreased from 238.806±639.060 to 152.255±266.558. Compared with the before treatment, the differences between the SRBC group and DRBC group were not statistically significant (P>0.05). Among all patients included in the statistics, the overall incidence of transfusion adverse reactions was 0.205% (6/2 916) in the SRBC group, and no adverse reactions occurred in the DRBC group. The incidence in the SRBC group was higher than that in the DRBC group. [Conclusion] Based on PSM analysis, there was no significant difference in the efficacy and safety of DRBC transfusion compared with SRBC transfusion, which can provide evidence-based support for routine application.

The neonatal mammalian heart has a remarkable regenerative capacity, while the adult heart has difficulty to regenerate. A metabolic reprogramming from glycolysis to fatty acid oxidation occurs along with the loss of cardiomyocyte proliferative capacity shortly after birth. In this study, we sought to determine if and how metabolic reprogramming regulates cardiomyocyte proliferation. Reversing metabolic reprogramming by carnitine palmitoyltransferase 1 (CPT1) inhibition, using cardiac-specific Cpt1a and Cpt1b knockout mice promoted cardiomyocyte proliferation and improved cardiac function post-myocardial infarction. The inhibition of CPT1 is of pharmacological significance because those protective effects were replicated by etomoxir, a CPT1 inhibitor. CPT1 inhibition, by decreasing poly(ADP-ribose) polymerase 1 expression, reduced ADP-ribosylation of dual-specificity phosphatase 1 in cardiomyocytes, leading to decreased p38 MAPK phosphorylation, and stimulation of cardiomyocyte proliferation. Our present study indicates that reversing metabolic reprogramming is an effective strategy to stimulate adult cardiomyocyte proliferation. CPT1 is a potential therapeutic target for promoting heart regeneration and myocardial infarction treatment.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

It designed standardized and personalized full process care service norms, providing references for medical institutions at all levels to promote the development of human caring for outpatients.

Objective:To evaluate the effects of different exercises on patients with chronic kidney disease based on network Meta-analysis so to provide a basis for medical and nursing staff to develop exercise programs.Methods:Randomized controlled trials on the effects of different exercises on patients with chronic kidney disease were electronically searched in databases such as Web of Science, PubMed, Embase, Cochrane Library, China Biology Medicine disc, WanFang Data, and China National Knowledge Infrastructure. The search period was from January 1, 2000, to March 1, 2023. Two researchers conducted literature screening, data extraction, and literature quality evaluation independently. The data was analyzed by using R software in conjunction with the gemtc package and plotted by using Stata software.Results:A total of 52 articles were included, with a cumulative sample size of 3 127 cases, involving three types of exercise (aerobic, resistance, and combined). The network Meta-analysis showed statistically significant differences between the three exercise methods and routine nursing in delaying renal function progression and improving cardiovascular endurance ( P<0.05). In controlling blood pressure and improving walking ability, the effects of three exercise methods were all superior to routine nursing, and the differences were statistically significant ( P<0.05). The area under the cumulative ranking probability curve showed that aerobic exercise>resistance exercise>combined exercise in terms of delaying renal function progression. In controlling blood pressure, resistance exercise>aerobic exercise>combined exercise. In terms of improving cardiovascular endurance, aerobic exercise>resistance exercise>combined exercise; In terms of improving walking ability, resistance exercise>combined exercise>aerobic exercise. Subgroup analysis showed that ≥ 24 weeks was the optimal intervention period for aerobic exercise. Resistance exercise intervention for ≥ 12 weeks could lower blood pressure, and intervention for ≤12 weeks could improve walking ability. However, when the intervention time was longer than 24 weeks, combined exercise had an excellent effect. Conclusions:Aerobic exercise is an excellent way to delay renal function progression and improve cardiovascular endurance. Resistance exercise is the optimal exercise method for controlling blood pressure and improving walking ability. Medical and nursing staff should choose appropriate types of exercise based on the patient's medical needs.

In order to understand the characteristics of avian leukosis virus(ALV)infection and the polymorphisms of receptor genes Tva,Tvb and NHE1 sequences in different Qingyuan Ma chick-en breeding farms,the isolation and identification of exogenous ALV virus,receptor gene amplifi-cation and sequencing analysis were carried out in five Qingyuan Ma chicken breeding farms.The results of virus isolation and subtype identification showed that the positive rate of exogenous ALV virus isolation in farms A,B and C was less than 5％,among which there was ALV-J infection alone in farm A,mixed infection with ALV-J and ALV-K in farm B,ALV-K infection a-lone in farm C,and no exogenous ALV infection was detected in farm D and E.Polymorphism anal-ysis of recipient genes showed that there were different frequencies of Tvar3,Tvar4 and Tvbr3 re-sistance alleles in A-E farms,and the distribution frequency of Tvar3 was 0.2-0.6,the distribution frequency of Tvar4 was 0.3-0.7,and the distribution frequency of Tvbr3 was 0.1-0.7.In addition,there were Tvar5 resistance alleles in both B and D farms,with a distribution frequency of 0.2.A to-tal of 18 SNP mutations occurred in the NHE1 receptor gene sequence,and further analysis showed that positions 1 279,1 361,1 369,1 406,1 442,and 1 912 were non-synonymous mutations,which could cause changes in amino acids.The study suggested that there were differences in the exogenous ALV and its subtypes among the five Qingyuan Ma chicken breeders,and each farm should have a more targeted and unique purification strategy.The distribution of Tva and Tvb re-sistance alleles at different frequencies,along with the occurrence of 6 non-synonymous mutations in the NHE1 gene,indicate that Qingyuan Ma chicken have the potential of genetic resistance breeding.

Objective To investigate the classification effect of deep neural networks in irregular time series data,and to predict the recurrence risk of 362 patients with diffuse large B-cell lymphoma(DLBCL)in a hospital in Shanxi from 2014 to 2020.Methods A total of 362 diagnosed DLBCL patients who achieved complete remission after initial chemotherapy were collected retrospectively,and the recurrence risk was predicted within the next two years.First,LASSO regression was used to screen the variables.Then a deep neural network model of irregular time series data based on GRU-ODE-Bayes was constructed and compared with some traditional models and other deep neural network models.Results Among all the models under study,the traditional models do not perform as well as the deep neural network models in classification.The GRU-ODE-Bayes model was the best,with AUC of 0.85,sensitivity of 0.84,specificity of 0.71,and G-means of 0.77.Conclusion Compared with other models,the GRU-ODE-Bayes model can predict the recurrence of DLBCL patients more accurately.It could benefit the individualized treatment for patients and decision-making for physicians.

Objectives:To investigate the clinical value of contrast echocardiography in the detection of right heart space-occupying lesions. Methods:The imaging and clinical data of 39 patients with right heart space-occupying lesions confirmed by surgery,pathology and clinical treatment in Yanbian University Hospital from January 2019 to January 2023 were retrospectively analyzed.All patients underwent contrast echocardiography and cardiac magnetic resonance(CMR)examinations.The contrast echocardiography features of right heart neoplastic from non-neoplastic occupying lesions were summarized.The diagnostic efficacy of contrast echocardiography and CMR in right heart space-occupying lesions was compared. Results:Among the 39 patients,12 patients(30.8%)were confirmed as thrombus and vegetation,6 patients(15.4%)as benign tumors and 21 patients(53.8%)as malignant tumors.There were 8,4,4 and 17 patients of thrombus,vegetation,benign tumor and malignant tumors located in right atrium,respectively.Contrast echocardiography was used to diagnose thrombus and vegetation in 12 patients(30.8%),benign tumors in 5 patients(12.8%),malignant tumors in 22 patients(56.4%).CMR was used to diagnose thrombus and vegetation in 18 patients(46.2%),benign tumors in 5 patients(12.8%),malignant tumors in 16 patients(41.0%).The Kappa coefficient between contrast echocardiography and clinical diagnosis was 0.956(P<0.001).The Kappa coefficient between CMR and clinical diagnosis was 0.754(P<0.001). Conclusions:Contrast echocardiography can dynamically observe the degree of vascularization in the lesion tissue in real-time,accurately distinguishing the nature of the right heart space-occupying lesions.
