The health of the human body is the result of the dynamic interplay between immunity and various microorganisms. Furthermore, the health of the mitochondrial grid determines the strength of immunity. Mitochondrial imbalance leads to the metabolic remodeling of intracellular nutrients, which accelerates the occurrence and development of tumors. The theory of yin and yang and the theory of visceral outward manifestation are the foundation and core of traditional Chinese medicine (TCM) theory, which guides the clinical diagnosis and treatment of TCM. Yang Qi is the driving force behind the metabolism and physiological functions of the human body; it is also the adenine nucleoside triphosphate produced efficiently by mitochondrial aerobic respiration. The main transport of spleen refers to the biological oxidation process of food in the mitochondria, and its normal function is closely related to the integrity of the mitochondrial structure and function of the cell. Therefore, warming yang and strengthening the spleen essentially means restoring the high production capacity of the mitochondria. Rebuilding damaged mitochondrial function, improving efficiency, and boosting the energy level of the neuro-endocrine-immune network are the key factors contributing to the body’s ability to resist disease and return to health.

BACKGROUND:Allogeneic hematopoietic stem cell transplantation is an effective and even the only way to cure various hematological diseases,but the short-term mortality rate is relatively high after transplantation. OBJECTIVE:To investigate the risk factors affecting the overall survival of patients with hematological diseases in the short term(within 100 days)after allogeneic hematopoietic stem cell transplantation,so as to reduce mortality and effectively prevent related risks in the short term(within 100 days)after allogeneic hematopoietic stem cell transplantation. METHODS:Clinical data of 585 patients with hematological diseases who underwent allogeneic hematopoietic stem cell transplantation at the Hematopoietic Stem Cell Transplantation Center of First Affiliated Hospital of Zhengzhou University from January 1,2018 to June 30,2021 were retrospectively analyzed.The risk factors that affected overall survival within 100 days after allogeneic hematopoietic stem cell transplantation were explored. RESULTS AND CONCLUSION:A total of 585 patients with hematologic diseases underwent allogeneic hematopoietic stem cell transplantation.92 patients died within 100 days after transplantation,with a mortality rate of 15.7%(92/585).The median age of death cases was 26.5 years old(1-56 years),and the median survival time of death cases was 48 days(0-97 days).Univariate analysis exhibited that age≥14 years old,acute graft-versus-host disease,grade IV acute graft-versus-host disease,bacterial bloodstream infection,as well as carbapenem-resistant organism bloodstream infection,were risk factors for overall survival within 100 days after allogeneic hematopoietic stem cell transplantation(P<0.05).Multivariate regression analysis showed that age≥14 years old,grades Ⅲ-Ⅳ acute graft-versus-host disease,bacterial bloodstream infection,and carbapenem-resistant organism bloodstream infections were independent risk factors for overall survival(within 100 days)in patients after allogeneic hematopoietic stem cell transplantation.Hazard ratios were 1.77(95%CI 1.047-2.991),7.926(95%CI 3.763-16.695),2.039(95%CI 1.117-3.722),and 3.389(95%CI 1.563-7.347),respectively.In conclusion,all-cause mortality rate after allogeneic hematopoietic stem cell transplantation is relatively high in the short term.A timely diagnosis and effective treatment of bacterial bloodstream infection and acute graft-versus-host disease are essential to improving allogeneic hematopoietic stem cell transplantation outcomes.

The online and offline hybrid teaching model of evidence-based medicine (EBM) is currently in the stage of development. Previous teaching focused on the teaching process in the classroom, and did not organically combine all the course contents before, during, and after class. The BOPPPS model can be used to establish coherence and integrity in the EBM teaching process. Considering the discipline characteristics and teaching objectives of EBM, this study initially explored and designed a BOPPPS-based online and offline hybrid teaching model. Taking the "diagnostic evidence" module as an example, the teaching implementation details were introduced. A pre-designed questionnaire was used to conduct baseline survey and follow-up survey on students before and after class to evaluate the teaching model and effect. The surveys showed that half of the students (77/154) preferred the new online and offline hybrid teaching model of EBM. The students found that all aspects of BOPPPS teaching were generally acceptable and satisfactory. Compared with before teaching, the students' proficiency in EBM was significantly improved after the teaching ( P<0.001), particularly in their ability to retrieve literature and evaluate the quality of evidence, which is of great significance for expanding their knowledge and clinical thinking.

Objective: To elucidate the biological basis of the heart qi deficiency (HQD) pattern, an in-depth understanding of which is essential for improving clinical herbal therapy. Methods: We predicted and characterized HQD pattern genes using the new strategy, TCM-HIN2Vec, which involves heterogeneous network embedding and transcriptomic experiments. First, a heterogeneous network of traditional Chinese medicine (TCM) patterns was constructed using public databases. Next, we predicted HQD pattern genes using a heterogeneous network-embedding algorithm. We then analyzed the functional characteristics of HQD pattern genes using gene enrichment analysis and examined gene expression levels using RNA-seq. Finally, we identified TCM herbs that demonstrated enriched interactions with HQD pattern genes via herbal enrichment analysis. Results: Our TCM-HIN2Vec strategy revealed that candidate genes associated with HQD pattern were significantly enriched in energy metabolism, signal transduction pathways, and immune processes. Moreover, we found that these candidate genes were significantly differentially expressed in the transcriptional profile of mice model with heart failure with a qi deficiency pattern. Furthermore, herbal enrichment analysis identified TCM herbs that demonstrated enriched interactions with the top 10 candidate genes and could potentially serve as drug candidates for treating HQD. Conclusion Our results suggested that TCM-HIN2Vec is capable of not only accurately identifying HQD pattern genes, but also deciphering the basis of HQD pattern. Furthermore our finding indicated that TCM-HIN2Vec may be further expanded to develop other patterns, leading to a new approach aimed at elucidating general TCM patterns and developing precision medicine.

Objective To evaluate the application value of the three-point localization method in improving the quality and efficiency of four-chamber view acquisition in cardiac magnetic resonance(CMR)imaging.Methods A total of 215 patients who underwent four-chamber view in CMR imaging from January 2022 to October 2023 were retrospectively enrolled and divided into two groups.The control group(n=109)received traditional localization method while the study group(n=106)received three-point localization method.The image quality of mitral valve,tricuspid valve and cruciform structure in four-chamber view images were assessed by two radiologists using a Likert 4-piont scale.The time-consumption from scout imaging to the finish of four-chamber view imaging was recorded.Constituent data and numeral data were compared by Chi-square test and two-sample t test,respectively.Kappa test was used to analyze the inter-observer consistency.Results There were no significant inter-group differences in gender,age,disease profile,or the radiographers'experience.The mean quality scores of the mitral valve,tricuspid valve and cruciform structure in the control group and the study group were 3.44±0.64 and 3.63±0.49(P=0.023),3.43±0.67 and 3.53±0.60(P=0.202),3.71±0.49 and 3.83±0.35(P=0.047),respectively.The image quality score was higher in the study group than in the control group,with the differences in mitral valve and cruciform structure reaching statistical significance.The time-consumption for obtaining four-chamber view for the control group and the study group was 11.67±3.49 minutes and 7.212±1.83 minutes,respectively,with statistically significant differences(P＜0.001).Conclusion Compared with the traditional localization method,the three-point localization method provides better image quality in four-chamber view imaging with shortened imaging time.

Objective To investigate the value of abdominal aortic combined with routine one-stop triple rule-out computed tomography angiography(TRO-CTA)in the examination of patients with acute chest pain.Methods A total of 1 482 patients with nontraumatic chest pain were included in this retrospective study.Of them 414 patients underwent the conventional TRO-CTA scanning while 1 068 patients underwent TRO-CTA that included the abdominal aorta(TRO-CTAwAA)under the request of clinicians.All scanning parameters were the same,except the scanning range for the third phase in TRO-CTA:conventional TRO-CTA covered only the thoracic aorta,while TRO-CTAwAA extended to the entire aorta.Patient etiology was investigated and the detection rates of major vessel abnormalities(aortic dissection,aneurysm,penetrating ulcer,intramural hematoma,vascular occlusion,and thrombosis)between the two groups was compared using chi square tests.The radiation dose(CTDIvol and DLP)and scanning time between the two groups were compared using analysis of variance(ANOVA).Results The TRO-CTAwAA had significantly higher detection rate of major artery abnormalities than the TRO-CTA group(35.1％vs.4.8％,P＜0.001).In the TRO-CTAwAA group,26.5％of the vascular anomalies were detected in both the thoracic and abdominal aortas,and another 8.6％were seen only in the abdominal aorta.With regard to the radiation dose between the two groups,the total DLP was significantly higher in the TRO-CTAwAA group than in the conventional TRO-CTA group(P＜0.001).The two groups did not significantly differ in scanning time(P=0.410).Conclusion TRO-CTA with scan range including the abdominal aorta significantly improves the detection rate for major vessel abnormalities in patients with chest pain without increasing the examination process.

Objective To evaluate the relationship between the pericoronary fat attenuation index(FAI)and the image reconstruction parameters of computed tomography(CT)coronary angiography,including reconstruction kernel,iterative reconstruction algorithm and image thickness.Methods Forty-four CT coronary angiography scans were prospectively enrolled.All scans were reconstructed by three means as follows:① Four different kernels(Soft_AA,Soft_BA,Soft_CA,and Soft_DA,sharpness from low to high)as the iterative reconstruction algorithm(KARL5)and image thickness(0.5 mm)remained unchanged.② Filtered back projection(FBP)and iterative reconstruction kernel(KARL5)as the kernel and image thickness(0.5 mm)remained unchanged.③ Different image thickness(0.5 mm and 1 mm)as the kernel(Soft_AA)and iterative reconstruction algorithm(KARL5)remained unchanged.The FAI of left anterior descending artery(LAD),left circumflex artery(LCX),and right coronary artery(RCA)was calculated using a dedicated software.Paired t-test and analysis of variance were used for statistical analysis.Results For LAD,LCX and RCA:① The differences of FAI among different reconstruction kernels reached statistical significance(P＜0.001),and FAI decreased as the sharper kernel was used.③ Compared with FBP,the FAI of KARL5-reconstructed images significantly increased(P＜0.001).③ Compared with 0.5 mm,the FAI of images with 1.0 mm thickness significantly decreased(P＜0.001).Conclusion The kernel,iterative reconstruction algorithms,and image thickness all have a significant impact on the FAI of each coronary artery.When using FAI for clinical diagnosis,the effect of CT reconstruction parameters should be taken into account.

Objective:To explore the posttraumatic growth of first stroke patients and analyze its dynamic development trajectory.Methods:From January to December 2022, 180 stroke patients admitted to Xinxiang Central Hospital were selected as research subjects by convenience sampling. The Posttraumatic Growth Inventory (PTGI) score was dynamically evaluated at the end of the first month (M 1), second month (M 2), third month (M 3), fourth month (M 4), fifth month (M 5), and sixth month (M 6) of onset. The latent class growth model (LCGM) was used to analyze the developmental trajectory categories, and multiple Logistic regression was used to analyze the influencing factors of posttraumatic growth trajectory categories. Results:A total of 180 questionnaires were distributed, and 177 valid questionnaires were collected, with a valid response rate of 98.33% (177/180). Within six months, the patient's PTGI score gradually increased, with the lowest PTGI score (29.11±5.65) at M 1 and the highest proportion of low-level growth, accounting for 85.31% (151/177). At M 6, the PTGI score was (42.14±13.04), and the proportion of low-level growth was 40.68% (72/177). Two latent categories of posttraumatic growth, namely sustained low growth type and growth improvement type, were identified, with 72 cases of sustained low growth type and 105 cases of growth improvement type. Gender ( OR=2.648, P=0.008), age ( OR=1.055, P=0.002), education level ( OR=6.403, P<0.001), and stroke type ( OR=2.863, P=0.014) were the influencing factors for posttraumatic growth trajectories among stroke patients. Conclusions:Post traumatic growth in stroke patients is a dynamic state of change, with low overall levels and a common type of sustained low growth. There may be differences in the sociodemographic and disease characteristics of patients with different types of posttraumatic growth trajectories, providing reference for the development of clinical nursing strategies, but further research is still needed.

Objective:To investigate the clinical, radiological, and pathological features of anaplastic gangliogliomas (AGGs) and to determine whether these tumors represent a distinct entity.Methods:Consecutive 667 cases of ganglioglioma (GG) diagnosed at the Xuanwu Hospital, Capital Medical University, Beijing, China between January 2015 and July 2023 were screened. Among these cases, 9 pathologically confirmed AGG cases were identified. Their clinical, radiological, treatment, and outcome data were analyzed retrospectively. Most of the tumor samples were subject to next-generation sequencing, while a subset of them were subject to DNA methylation profiling.Results:Among the 9 patients, there were five males and four females, with a median age of 8 years. Epileptic seizures (5/9) were the most frequently presented symptom. Radiological examinations showed three types of radiological manifestations: four cases showed abnormal MRI signals with no significant mass effects and mild enhancement; two cases demonstrated a mixed solid-cystic density lesion with peritumoral edema, which showed significant heterogeneous enhancement and obvious mass effects, and one case displayed cystic cavity formation with nodules on MRI, which showed evident enhancements. All cases exhibited mutations that were predicted to activate the MAP kinase signaling pathway, including seven with BRAF p.V600E mutation and two with NF1 mutation. Five AGGs with mutations involving the MAP kinase signaling pathway also had concurrent mutations, including three with CDKN2A homozygous deletion, one with a TERT promoter mutation, one with a H3F3A mutation, and one with a PTEN mutation.Conclusions:AGG exhibits a distinct spectrum of pathology, genetic mutations and clinical behaviors, differing from GG. Given these characteristics suggest that AGG may be a distinct tumor type, further expansion of the case series is needed. Therefore, a comprehensive integration of clinical, histological, and molecular analyses is required to correctly diagnose AGG. It will also help guide treatments and prognostication.

Objective:To explore the clinical and genetic characteristics of four children with Kabuki syndrome (KS) due to variants of KMT2D gene. Methods:Four children with KS diagnosed at the Children′s Hospital of Shanxi Province between January 2020 and December 2022 were selected as the study subjects. Whole exome sequencing was carried out for the children and their family members. Candidate variants were verified by Sanger sequencing and pathogenicity analysis.Results:The KS phenotype scores for the four children were 7, 8, 6, and 6, respectively. Child 2 also presented with a rare solitary kidney malformation. Genetic testing revealed that all children had harbored novel de novo variants of the KMT2D gene, including c. 16472_16473del, c. 858dup, c. 11899C>T, and c. 12844C>T, respectively. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), all of the variants were classified as pathogenic. Conclusion:For children showing phenotypes such as distinctive facial features, intellectual disability, developmental delay, cardiac abnormalities, and urinary system anomalies, KS should be considered. Early diagnosis and intervention can be achieved through genetic testing, especially in the presence of KMT2D gene mutations.
