[Objective] To investigate the non-pathological influencing factors of the unqualified alanine aminotransferase (ALT) in the initial screening of blood donors in Changchun and the laboratory re-examination, so as to provide evidence for reducing the deferral of blood donors and the discarding of blood due to ALT disqualification. [Methods] The unqualified results of ALT from the laboratory of our center from September 1, 2023 to October 31, 2024 were collected. The unqualified rates of ALT were statistically analyzed according to the blood collection sites and the initial screening detection equipment. The samples after ALT pre-donation screening were tested in the laborator, and the unqualified rates of ALT in the initial screening and the laboratory, the non-conformity rate of the results and the distribution range of ALT values were statistically analyzed according to the blood collection sites and the initial screening detection equipment. A questionnaire survey was conducted on the blood donors before blood collection to statistically analyze the influence of the blood donors' living habits and diet on ALT test results. [Results] The statistical analysis of the unqualified rate of ALT in the laboratory showed statistically significant differences in the ALT disqualification rates among different blood collection sites and different initial screening detection devices (P<0.05). Comparison of the ALT unqualified rate for the same type of equipment at different sites showed that for Equipment 1, there were differences between the combined blood collection house and the whole blood house, and between the combined blood collection house and the blood donation vehicle (P<0.05); for Equipment 2, there were differences between the combined blood collection house and the blood donation vehicle, and between the whole blood house and the blood donation vehicle (P<0.05); there were no significant differences among other groups with the same equipment. The initial screening and the laboratory test results for the same samples were compared, with unqualified rates of ALT of 16.29% and 13.01%, respectively. There were statistically significant differences in the unqualified rates of ALT among different blood collection sites (P<0.05), but no significant differences in the ALT test results among different detection equipment (P>0.05).. The non-conformity rate between the initial screening and the laboratory results was 5.26%, of which 81.15% (99/122) were unqualified in the initial screening but qualified in the laboratory. There were statistically significant differences in those unqualified in the initial screening but qualified in the laboratory among different blood collection sites and different detection equipment (P<0.05). The median ALT level in the initial screening was 29.0 U/L (with a 5%-95% range of 14-75 U/L), and the median ALT level in the laboratory was 19 U/L (with a 5%-95% range of 8-65 U/L). The results of the questionnaire survey showed that 33.3% (2/6) of those who consumed alcohol within 24 hours before blood donation had unqualified ALT, and 10% (1/10) of those who stayed up late the night before blood donation had unqualified ALT. [Conclusion] The unqualified rates of ALT in the initial screening before blood collection and the laboratory re-examination of blood donors in Changchun are closely related to the blood collection sites, detection equipment, detection environment, detection personnel, samples, ALT thresholds and detection time. Drinking alcohol and staying up late within 24 hours before blood donation increase the risk of unqualified ALT detection.

Objective To determine the prognostic biomarkers and new therapeutic targets of the lung adenocarcinoma (LUAD), based on which to establish a prediction model for the survival of LUAD patients. Methods An integrative analysis was conducted on gene expression and clinicopathologic data of LUAD, which were obtained from the UCSC database. Subsequently, various methods, including screening of differentially expressed genes (DEGs), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and Gene Set Enrichment Analysis (GSEA), were employed to analyze the data. Cox regression and least absolute shrinkage and selection operator (LASSO) regression were used to establish an assessment model. Based on this model, we constructed a nomogram to predict the probable survival of LUAD patients at different time points (1-year, 2-year, 3-year, 5-year, and 10-year). Finally, we evaluated the predictive ability of our model using Kaplan-Meier survival curves, receiver operating characteristic (ROC) curves, and time-dependent ROC curves. The validation group further verified the prognostic value of the model. Results The different-grade pathological subtypes' DEGs were mainly enriched in biological processes such as metabolism of xenobiotics by cytochrome P450, natural killer cell-mediated cytotoxicity, antigen processing and presentation, and regulation of enzyme activity, which were closely related to tumor development. Through Cox regression and LASSO regression, we constructed a reliable prediction model consisting of a five-gene panel (MELTF, MAGEA1, FGF19, DKK4, C14ORF105). The model demonstrated excellent specificity and sensitivity in ROC curves, with an area under the curve (AUC) of 0.675. The time-dependent ROC analysis revealed AUC values of 0.893, 0.713, and 0.632 for 1-year, 3-year, and 5-year survival, respectively. The advantage of the model was also verified in the validation group. Additionally, we developed a nomogram that accurately predicted survival, as demonstrated by calibration curves and C-index. Conclusion We have developed a prognostic prediction model for LUAD consisting of five genes. This novel approach offers clinical practitioners a personalized tool for making informed decisions regarding the prognosis of their patients.

Objective:To explore the clinical value of a trinity strategy for the treatment of multiple orthopedic trauma.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 267 patients with multiple orthopedic trauma admitted to Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the First Affiliated Hospital of Navy Medical University from June 2013 to May 2023, including 862 males and 405 females, aged 18-93 years [(55.2±19.8)years]. Associated injuries included hemorrhagic shock in 632 patients, traumatic wet lung in 274, cranial injuries in 135, abdominal and pelvic bleeding in 116, pneumothorax in 89, urinary injury in 13, and vesical rupture in 8. All the patients were treated with the trinity strategy and the treatment process was divided into the phases of first aid, remodeling, and rehabilitation. The first aid phase focused on stabilizing symptoms and saving lives; the remodeling phase centered on restoring the anatomical structure and alignment; the rehabilitation phase aimed for functional recovery through the integration of both Western and traditional Chinese medicine. The all-cause mortality within 30 days after surgery and fracture healing time were calculated; the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, Hospital for Special Surgery (HSS) knee score and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score at the last follow-up and the overall excellent and good rate of all joint function scores were measured. The short form health survey (SF-36) scores were collected preoperatively and at 6 months postoperatively, including 8 aspects such as physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health. The incidence of postoperative complications was recorded.Results:All the patients were followed up for 6-18 months [(10.2±4.2)months]. The mortality rate during the acute phase (within 30 days after surgery) was 2.37% with 12 deaths due to hemorrhagic shock, 10 due to traumatic brain injury, 6 due to multiple organ dysfunction syndrome (MODS), and 2 due to pulmonary infection. The average fracture healing time averaged 3.8-18 months [(11.5±4.2)months], with 89.49% of the patients having bone union within 12 months after surgery, 8.93% having bone union within 18 months after surgery, and 1.58% undergoing reoperation. For the patients with internal fixation failure and nonunion, the average healing time was extended to (10.2±2.2)months and (13.7±3.3)months respectively. At the last follow-up, the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, HSS knee score, and AOFAS ankle-hindfoot score were 83.93%, 90.24%, 94.12%, 85.57%, 88.46%, and 92.31% respectively, with an overall excellent and good rate of 89.11%. At 6 months after surgery, the SF-36 scores of all the patients in the eight dimensions,including the physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health were (74.4±8.6)points, (44.7±14.4)points, (77.4±10.9)points, (68.4±18.2)points, (72.5±16.0)points, (76.8±8.7)points, (49.9±17.6)points, and (72.8±17.9)points, significantly improved compared with those before operation [(63.4±12.7)points, (30.9±17.4)points, (56.4±18.0)points, (55.4±24.7)points, (53.5±21.0)points, (55.8±24.3)points, (36.9±24.0)points, (58.8±21.6)points] ( P<0.01). Complications of different degrees occurred in 214 patients (16.89%), including lung infections in 118 patients (9.31%), lower extremity deep vein thrombosis in 50(3.95%), pressure injuries in 26(2.05%), internal fixation failure in 12(0.95%), and nonunion in 8(0.63%). Conclusions:The trinity strategy provides whole-process management, personalized treatment, and overall rehabilitation for multiple orthopedic trauma. It can decrease mortality, shorten fracture healing time, improve joint function and quality of life, and reduce the incidence of complications.

OBJECTIVE To investigate the inhibitory effect and mechanism of 5,6-dimethylxanthe-none-4-acetic acid(DMXAA)on metastasis of Lewis lung cancer(LLC)in mice.METHODS The inhibi-tory effect of DMXAA on tumor metastasis was analyzed via an LLC xenograft tumor model and LLC metastatic tumor model.The mice of LLC xenograft tumor model were randomly divided into three groups:model group(physiological saline containing 1%DMSO,ip,once every two days),model+suni-tinib group(30 mg·kg-1,ip,once every two days),and model+DMXAA group(25 mg·kg-1,ip,once).Tumor volume and body mass were measured once every two days after administration.Two and five days after administration,tumor mass was measured by sacrificing the mice,followed by immunofluores-cence staining of tumor tissues.Platelet/endothelial cell adhesion molecule-1(CD31)and α-smooth muscle actin(α-SMA)were used to analyze the vascular structure of tumor tissues.The tumor hypoxia level was detected using the hypoxia probe pimonidazole staining.The mice of LLC metastatic tumor model were randomly divided into three groups:model group(physiological saline containing 1%DMSO,ip,twice a week),model+sunitinib group(60 mg·kg-1,ip,twice a week),and model+DMXAA group(25 mg·kg-1,ip,once).At the Two and five weeks after administration,the in vivo tumor growth and metastasis were observed and quantified using a small animal live imaging system.RESULTS Compared with the model group,the tumor volume and mass of the model+sunitinib group and model+ DMXAA group were significantly reduced(P<0.05,P<0.01),and DMXAA took effect faster and more significantly than sunitinib.At the same time,compared with the model group,the body mass in the model+sunitinib group decreased significantly(P<0.05),but there was no significant difference in body mass the model+DMXAA group.Compared with the model group,model+sunitinib had no effect on tumor metastasis,but model+DMXAA significantly reduced tumor metastasis two weeks after administration(P<0.01).Compared with the model group,the coverage rate of α-SMA/CD31 in the model+sunitinib group and model+DMXAA group increased significantly(P<0.05).Compared with the model group,there was no significant change in the tumor hypoxia area in the model+sunitinib group,but this in the model+DMXAA group decreased significantly(P<0.01).CONCLUSION DMXAA significantly inhibits the growth and metastasis of LLC in mice,and its mechanism may be related to its improvement of tumor vascular normalization and hyposic microenvironments.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.
