Objective To systematically evaluate the similarities between six-gene-modified pig red blood cells and human red blood cells in multiple dimensions, including cell morphology, hematological parameters, microbial safety and serological compatibility, and to verify the feasibility of using six-gene-modified pig red blood cells as an alternative for blood transfusion in cases of traumatic hemorrhage. Methods Blood samples from O-type human donor, six-gene-modified O-type pig and wild-type O-type pig were collected. The pig gene-modified phenotype was identified by flow cytometry. The morphology was observed using field emission scanning electron microscopy and the diameter was measured. Hematological tests, including blood routine, osmotic fragility test, adenosine triphosphate (ATP) and 2,3-diphosphoglycerate (2,3-DPG) content and partial pressure of oxygen at 50% hemoglobin saturation (P50), were conducted to assess the deformability of red blood cells. Real-time fluorescent quantitative polymerase chain reaction was used to screen for zoonotic viruses, and cross-matching was performed using column gel method, condensation amine method and saline tube method. Results The six-gene-modified pig red blood cells successfully knocked out the α-Gal, Neu5Gc and Sda antigens and expressed hCD55. Wild-type pig red blood cells expressed these three antigens but did not express human complement regulatory proteins. All three types of red blood cells presented a biconcave discoid morphology. The diameter of O-type human red blood cells was larger than that of the six-gene-modified porcine red blood cells and wild-type pig red blood cells (all P < 0.05). The average red blood cell volume and average red blood cell hemoglobin of O-type humans were higher than those of the six-gene-modified pig red blood cells, and the distribution width-variable coefficient of O-type human red blood cells was lower than that of the six-gene-modified pig red blood cells (all P < 0.05). There were no statistically significant differences in the permeability fragility, ATP content, 2,3-DPG content, P50 and red blood cell deformability indicators of the three types of red blood cells (all P > 0.05). The screening for zoonotic viruses in human and animal cells of the six-gene-modified pigs and wild-type pigs was negative. The cross-matching results showed that in the column gel method and condensation amine method, the primary and secondary sides of the six-gene-modified pig red blood cells did not agglutinate with human red blood cells, while the wild-type pig red blood cells agglutinated with human red blood cells in all cross-matching methods. Conclusions The six-gene-modified pig red blood cells are highly similar to human red blood cells in terms of morphology, key hematological parameters, energy metabolism, oxygen-carrying capacity, mechanical properties, microbial safety and serological compatibility, providing an experimental basis for the clinical transformation of xenotransfusion.

Objective:To analysis of the latent profiles and influencing factors of body image in patients with postoperative oral cancer.Methods:From July 2024 to March 2025, a total of 332 patients with primary oral cancer confirmed by pathology, aged ≥18 years, and undergoing oral cancer surgery at Hunan Cancer Hospital were selected using simple random sampling and cluster sampling. Among them, 25 were female and 307 were male. The body image scale and the Rosenberg self-esteem scale were used to investigate the patients. The main indicators included the total scale scores and scores on various dimensions of body image, such as appearance evaluation and health focus, with particular attention to satisfaction with facial appearance and oral function.The correlation between self-esteem and body image was analyzed, and differences in scores were compared based on gender, age, self-esteem level, and surgical procedure.Results:Among the 332 patients, 93.4% (310/332) were married, and 6.6% (22/332) were unmarried, divorced, or widowed. A total of 84.3% (280/332) underwent flap transplantation surgery, while 15.7% (52/332) did not. The body image distress in the 332 patients could be categorized into a body image adaptation group [80.12% (266/332)] and a body image disorder group [19.88% (66/332)]. Unmarried/divorced/widowed status ( P=0.020), undergoing flap transplantation ( P=0.006), and self-esteem level ( P<0.001) were identified as influencing factors for postoperative body image disorder in oral cancer patients. Conclusions:Given the varying levels of body image concerns among oral cancer patients, healthcare providers can implement targeted, personalized nursing interventions based on their distinct categories and influencing factors.

Objective To investigate the impact of phase Ⅱ cardiac rehabilitation on the rehabilitation needs and physical activity status of patients after coronary heart disease intervention.Methods A total of 90 patients with coronary heart disease who underwent percutaneous coronary intervention(PCI)in the Coronary Heart Disease Center of the hospital from August 2023 to August 2024 were selected as the research subjects.They were subjected to a 12-week standardized phase Ⅱ cardiac rehabilitation training.General data survey forms,cardiac rehabilitation scales,and the International Physical Activity Questionnaire were used for scale surveys to understand the patients' needs before and after rehabilitation and their weekly physical activity en-ergy expenditure.The cardiopulmonary exercise test gold standard,which reflects exercise capacity through three indicators-maximum oxygen uptake(VO2 max),anaerobic threshold(AT),and metabolic equivalents(MET),were used to compare the physical activity status before and after cardiac rehabilitation.Results Compared with before the implementation,after the implementation of cardiac rehabilitation,the autonomy score in-creased(21.36±1.85 vs.16.73±3.28),the process anxiety(12.60±3.87 vs.14.27±2.12)and outcome anxiety scores(2.31±1.76 vs.4.56±3.56)decreased,the level of low-intensity physical activity decreased[(2 711.62±1 487.09)min/week vs.(3 845.97±2 083.71)min/week],the levels of moderate-intensity[(1 314.67±783.54)min/week vs.(686.22±126.79)min/week],high-intensity[(1 861.33±798.27)min/week vs.(112.00±40.77)min/week],and total physical activity increased[(5 887.62±2 843.54)min/week vs.(4 644.19±2 287.16)min/week].The levels of VO2 max[(28.11±14.28)mL·min-1·kg-1 vs.(23.82±12.34)mL·min-1·kg-1],AT[(16.06±5.41)mL·min-1·kg-1 vs.(13.53±4.56)mL·min-1·kg-1],and MET[(6.89±1.59)mL·min-1·kg-1 vs.(5.78±1.21)mL·min-1·kg-1]all in-creased,with statistically significant differences(P＜0.05).Conclusion Phase Ⅱ rehabilitation after PCI can effectively improve patients' physical activity levels.

BACKGROUND:Osteoarthritis is a complex disease closely related to metabolic abnormalities.However,previous studies only involved limited blood lipid indicators and did not conduct more comprehensive blood lipid profile analysis.An in-depth exploration of the causal relationship between the seven items of blood lipids and osteoarthritis will not only help understand the pathogenesis of osteoarthritis,but also provide new research directions and clinical basis for its prevention and treatment.OBJECTIVE:To explore the causal relationship between blood lipids and osteoarthritis.METHODS:The genome-wide association analysis statistical data of 7 items of blood lipids and osteoarthritis from the IEU OPEN GWAS database were used to summarize,and significant single nucleotide polymorphisms were used as instrumental variables.The causal relationship between seven items(serum total cholesterol,triacylglycerol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,apolipoprotein B,apolipoprotein AI and apolipoprotein A1)of blood lipids and osteoarthritis(osteoarthritis,knee or hip osteoarthritis,knee osteoarthritis and hip osteoarthritis)was determined through two-sample Mendelian randomization analysis.The inverse variance weighting was the main effect,and the MR-Egger regression method and the weighted median method were the supplementary effects.Bonferroni correction and reverse Mendelian randomization analysis could ensure validity.Multivariable Mendelian randomization analysis was used to further eliminate confounding factors.A significant causal relationship between seven items of blood lipids and osteoarthritis was obtained to ensure the robustness of the analysis.Co-localization analysis was used to once again ensure the robustness of the causal relationship and identify significantly influencing gene loci,making the evidence of causality more complete.RESULTS AND CONCLUSION:(1)In the two sample Mendelian randomization analysis,the results from inverse variance weighting indicated negative correlations between osteoarthritis and the following serum lipids:total cholesterol(OR=0.937 2,95%CI=0.885 6-0.991 9,P=0.025),low-density lipoprotein cholesterol(OR=0.959 4,95%CI=0.923 6-0.996 6,P=0.033),high-density lipoprotein cholesterol(OR=0.911 2,95%CI=0.833 5-0.996 2,P=0.04),apolipoprotein B(OR=0.926 7,95%CI=0.887 7-0.967 4,P=0.000 5),and apolipoprotein AI(OR=0.951 2,95%CI=0.911 0-0.993 1,P=0.023).Additionally,total cholesterol(OR=0.892 3,95%CI=0.843 1-0.944 3,P=0.000 08),triglycerides(OR=0.938 5,95%CI=0.884 7-0.995 6,P=0.035),and apolipoprotein B(OR=0.911 6,95%CI=0.865 9-0.959 7,P=0.000 4)were negatively associated with knee or hip osteoarthritis.For knee osteoarthritis specifically,total cholesterol(OR=0.898 3,95%CI=0.841 2-0.959 3,P=0.001),high-density lipoprotein cholesterol(OR=0.881 2,95%CI=0.794 7-0.977 0,P=0.016),and apolipoprotein B(OR=0.919 0,95%CI=0.869 8-0.971 0,P=0.002)also showed negative correlations.Lastly,with respect to hip osteoarthritis,total cholesterol(OR=0.864 5,95%CI=0.797 5-0.937 3,P=0.000 4),low-density lipoprotein cholesterol(OR=0.925 6,95%CI=0.879 5-0.974 1,P=0.003),and apolipoprotein B(OR=0.888 8,95%CI=0.817 6-0.966 3,P=0.005)exhibited negative correlations.No statistically significant differences were found in the reverse Mendelian randomization analysis.(2)In the multivariable Mendelian randomization analysis,the results from inverse variance weighting indicated a negative correlation between high-density lipoprotein cholesterol and osteoarthritis(OR=0.942 7,95%CI=0.896 1-0.991 8,P=0.022).Additionally,total cholesterol(OR=0.799 8,95%CI=0.647 8-0.987 6,P=0.037)and high-density lipoprotein cholesterol(OR=0.865 1,95%CI=0.7781-0.961 9,P=0.007)were also negatively associated with knee osteoarthritis.(3)Colocalization analysis revealed that total cholesterol and low-density lipoprotein were significantly associated with osteoarthritis at single nucleotide polymorphisms rs13107325(H4 posterior probability=99.9%).(4)These findings,using international databases and non-Asian populations,provide valuable insights for early clinical diagnosis,understanding the pathogenesis,and researching prevention and treatment of osteoarthritis in Chinese biomedicine and the Chinese population.

Objective:To compare percutaneous Kirschner wiring and elastic intramedullary nailing after ultrasound-guided reduction in the treatment of radial neck fractures in children.Methods:A retrospective study was conducted to analyze the 96 children with radial neck fracture who had been admitted to Department of Orthopedics, Children's Hospital of Anhui Province from January 2020 to January 2023. They were 51 boys and 45 girls with an age of (7.0±2.5) years. By the Judet classification, there were 74 cases of type Ⅲ and 22 cases of type IV. Twenty-one cases were treated with percutaneous Kirschner wiring after ultrasound-guided reduction (Kirschner wire group) while 75 cases with elastic intramedullary nailing after ultrasound-guided reduction (intramedullary nail group). The surgical time, fluoroscopy frequency, fracture healing time, and incidence of complications were compared between the 2 groups. Their postoperative X-ray films were evaluated according to the Métaizeau criteria, and elbow joint function was evaluated according to the Steel and Gtrham scoring at the last follow-up.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The 96 pediatric patients were followed up for (10.6±4.2) months after surgery. The surgical time [(18.5±2.6) minutes] and fluoroscopy frequency [4.0 (3.0, 4.0) times] in the Kirschner wire group were significantly less than those in the intramedullary nail group [(30.9±2.7) minutes, 8.0 (7.0, 9.0) times] ( P<0.05). There was no statistically significant difference in fracture healing time, good and excellent rate of postoperative reduction by the Métaizeau criteria, good and excellent rate of elbow joint function by the Steel and Gtrham scoring at the last follow-up, or incidence of complications ( P>0.05). Conclusion:In the treatment of radial neck fractures in children, both ultrasound-guided percutaneous Kirschner wiring and elastic intramedullary nailing after ultrasound-guided reduction can lead to similar therapeutic effects, but the former can shorten surgical time, reduce intraoperative fluoroscopy frequency, and spare a secondary surgery.

Objective To investigate the current status of knowledge-attitude-practice of cardiac rehabilitation in patients undergoing coronary artery bypass grafting(CABG) and analyze its influencing factors. Methods From July to November 2022, 288 patients with CABG in the coronary heart disease surgery center of Beijing Anzhen Hospital Affiliated to Capital Medical University were conveniently included, and general information questionnaire and cardiac rehabilitation knowledge and practice questionnaire were used to investigate the general situation and the level of knowledge-attitude-practice of cardiac rehabilitation in patients with coronary heart disease. Results A total of 290 questionnaires were sent out in this study, and 288 were effectively collected, with an effective recovery rate of 99.31%. The total score of the questionnaire was (106.81±13.35), and the total score rate was 62.83%, including the knowledge questionnaire scoring (39.34±9.13), belief questionnaire scoring (32.86±3.39) and behavior questionnaire scoring (34.61±3.54). The scoring rates of knowledge, attitude and practice questionnaire were 46.28%, 82.15% and 76.91%, respectively. Multiple linearregression analysis showed that patients who lived in rural areas, had education background of primary school or below, were farmers, had public health insurance, and had no previous coronary intervention, had lower levels of knowledge-attitude-practice of cardiac rehabilitation (P < 0.05). Conclusion The knowledge-attitude-practice of cardiac rehabilitation, especially the level of knowledge, in patients with CABG is needed to be improved. The factors that affect the level of knowledge-attitude-practice of cardiac rehabilitation in this population are diversified, suggesting that individual cardiac rehabilitation guidance should be implemented according to different people and local conditions, and diversified cardiac rehabilitation models should be established to improve the long-term and compliance of cardiac rehabilitation.

Diabetic peripheral neuropathy （DPN） is one of the common complications of diabetes. The disease has a long course with nerve pain and other symptoms， seriously affecting the quality of life of patients. DPN is related to high glucose in vivo， inflammation， oxidative stress， apoptosis， and autophagy， involving phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， nuclear factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， and other signaling pathways. At present， the treatment of DPN mainly focuses on symptomatic treatments such as blood glucose control and neurotrophic therapy， but the effect is not ideal. Therefore， it is particularly important to select a reasonable and effective drug to prevent and treat DPN. In recent years， Chinese medicine has played an important role in the treatment of DPN. Many studies have explored the mechanism of Chinese medicine in the treatment of DPN， and it has been found that some Chinese medicine monomers and compounds can regulate signaling pathways to prevent and treat DPN. This paper reviewed the research results of signaling pathways involved in DPN and the regulation of related pathways by Chinese medicine， aiming to provide references for the clinical treatment of DPN.

Objective:To clarify the clinical efficacy of first-line oral antiviral drugs tenofovir alafenamide (TAF), tenofovir disoproxil fumarate (TDF), and entecavir (ETV) in the treatment of chronic hepatitis B (CHB) and their safety profiles with lipid, bone, and kidney metabolism.Methods:458 CHB cases diagnosed and treated at the Department of Hepatology of Integrated Traditional Chinese and Western Medicine of the Third Hospital of Hebei Medical University from February 2010 to November 2022 were selected. TAF (175 cases), TDF (124 cases), and ETV (159 cases) were used as therapies. At 24 and 48 weeks, the virology, biochemical response, changes in liver stiffness measurement (LSM), and bone, kidney, and blood lipid metabolism safety profiles were compared and analyzed.Results:After 24 and 48 weeks of TAF, TDF, and ETV therapy, HBV DNA load decreased by 3.28, 2.69, and 3.14 log10 IU/ml and 3.28, 2.83, and 3.65 log10 IU/ml, respectively, compared with the baseline, and the differences between the three groups were statistically significant, P < 0.001. The complete virological response rates were 73.95%, 66.09%, 67.19%, and 82.22%, 72.48%, and 70.49%, respectively. The incidence rates of low-level viremia were 16.67%, 21.70%, and 23.08%, while poor response rates were 1.11%, 3.67%, and 4.10%. ALT normalization rates were 64.00%, 63.89%, 67.96%, and 85.33%, 80.56%, 78.64%, respectively, and there was no statistically significant difference among the groups. LSM was significantly improved in patients treated with TAF for 48 weeks, P = 0.022. Serum phosphorus level gradually decreased with the prolongation of TDF treatment. The TAF treatment group had a good safety profile for kidney, bone, and phosphorus metabolism, with no dyslipidemia or related occurrences of risk. Conclusion:There are some differences in the therapeutic effects of first-line anti-HBV drugs. TAF has the lowest incidence of low-level viremia after 48 weeks of treatment and has a good safety profile in kidney, bone, and blood lipid metabolism.
