With the rapid development of mobile internet technology, mobile health application (mHealth APP) are increasingly widely used in the field of health management and have been proven to play an important role in the management of chronic diseases. Solid organ transplant recipients face complex health management needs after surgery, including postoperative follow-up, medication management, prevention and treatment of complications and comorbidities, and lifestyle adjustment. mHealth APP can provide solid organ transplant recipients with convenient self-management tools. Although some progress has been made in this field, there are still many challenges, such as insufficient user experience, technological dependence, and data security risks. Therefore, this article discusses the development process, main functions and current application status of mHealth APP, and analyzes its advantages in improving the self-management ability of solid organ transplant recipients, promoting doctor-patient communication and reducing the incidence of complications. At the same time, based on the practical experience of author’s team in developing the “TransMate” mHealth APP, we propose the directions that mHealth APPs should focus on in the future, in order to provide more effective support and services for the health management of solid organ transplant recipients.

Exercise, as a non-pharmacological intervention, holds a pivotal role in metabolic regulation, neuroplasticity, and immune homeostasis maintenance. However, human exercise studies are constrained by ethical limitations in tissue sampling, especially for key organs such as muscles and the brain. Meanwhile, rodent models like mice exhibit physiological differences in exercise patterns and metabolic rates from human. Despite these challenges, approximately 70% of human and mouse genes are conserved, providing a molecular basis for cross-species comparisons. This paper leverages the GEPREP database, which integrates human and mouse exercise transcriptomic data from multiple platforms, to conduct a comprehensive cross-species analysis of exercise-induced gene expression patterns. We employ a stringent data standardization process, including the conversion of orthologous genes and the filtering of low-expressing genes, to ensure the accuracy and reliability of the analysis. A mixed-effects model is utilized to assess differential gene expression across multiple cohorts, identifying genes that are significantly upregulated or downregulated in response to exercise. The analysis reveals a complex pattern of gene expression, with a significant number of genes showing conserved responses between humans and mice, particularly in acute aerobic exercise, where genes such as ATF3, PPARGC1A, and ANKRD1 are commonly upregulated. These genes are implicated in muscle stress response, metabolic regulation, and muscle adaptation, highlighting the shared molecular pathways activated by exercise across species. However, the study also uncovers substantial species-specific differences in gene expression, especially in chronic aerobic exercise, where the number of divergently regulated genes increases. These differences suggest that while some fundamental biological processes are conserved, the specific regulatory mechanisms and gene expression patterns can vary significantly between humans and mice. Functional enrichment analysis further reveals that conserved genes are involved in muscle development, inflammation regulation, and energy metabolism, while species-specific genes are associated with ion transport, extracellular matrix (ECM) organization, and muscle contraction, indicating the multifaceted impact of exercise on skeletal muscle function. The findings emphasize the importance of considering species-specific differences when interpreting results from animal models and translating them to human health applications. The study highlights the need for a more nuanced understanding of the molecular underpinnings of exercise-induced adaptations and underscores the value of cross-species comparative analyses in uncovering the evolutionary and functional basis of these responses. Future research should focus on integrating multi-omics data and expanding the analysis to include other tissues to provide a more comprehensive view of the systemic effects of exercise. Additionally, the development of species-specific gene editing models and the validation of key genes in exercise physiology will further enhance our understanding of the evolutionary logic behind exercise interventions. This study not only provides valuable insights into the molecular mechanisms of exercise-induced adaptations but also underscores the necessity of validating findings from animal models in human cohorts to ensure the reliability and applicability of translational research in exercise science. By addressing these aspects, the study aims to bridge the gap between basic research and clinical applications, ultimately contributing to the development of personalized exercise prescriptions and interventions that can effectively promote health and prevent diseases.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.

Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.

Aim To investigate the protective effects of co-administered piperine on reversing the skeletal deterioration induced by fluoxetine.Methods Female ovariectomized rats were orally administered with estra-diol,fluoxetine,piperine and the mixture of piperine and fluoxetine for eight weeks,respectively.X-ray ab-sorption assay was used to determine bone mineral den-sity(BMD).microCT was used to analyze the effects of drug treatments on micro-architecture,three-bending test was performed to examine the biomechanical prop-erties.ELISA kits were employed to quantify the bone turnover markers in serum.Besides,rat primary osteo-blasts were cultured to investigate the osteoblastogene-sis and mineralization in the presence of fluoxetine with or without piperine.Results Compared with ovariec-tomized rats,the administration of estradiol and piper-ine significantly enhanced BMD and biomechanical properties with improved micro-architecture of trabecu-lar bones.Fluoxetine treatment further deteriorated BMD,biomechanical properties and micro-architecture of ovariectomized rats with accelerated bone turnover.Concomitant administration of piperine with fluoxetine significantly suppressed the deteriorating effects on skeleton by fluoxetine.In addition,fluoxetine reduced the differentiation and mineralization of primary osteo-blasts,whereas combined therapy showed promotional effects.Conclusions The administration of fluoxetine induces further bone loss in ovariectomized rats by in-hibiting osteoblastic differentiation and mineralization.The co-administration of piperine with fluoxetine rever-ses its skeletal deterioration.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.

Objective To evaluate the feasibility and accuracy of virtual preoperative planning and 3D-printed templates for pre-contoured plates for the treatment of posterior wall fractures of the acetabulum.Methods A retrospective analysis of 29 patients with posterior acetabular wall fractures treated between August 2017 and March 2021 were divided into 2 groups based on whether to use preoperative virtual planning and 3D printed template.In 3D-printing group,there were 14 patients,includ-ing 10 males and 4 females;aged from 21 to 53 years old;CT-based virtual surgical planning was done using Mimics and 3-Matic software and 3D-printed templates for pre-contoured plates were adopted.In conventional group,there were 15 patients,including 10 males and 5 females;aged from 19 to 55 years old;conventional method of intra-operative contouring to adapt the plate to the fracture region was adopted.Blood loss,surgical time,radiographic quality of reduction,and hip function were compared between groups.Results The difference in operation time and intraoperative blood loss was significant(P＜0.05).Twenty-three patients were followed up from 12 to 30 months,and the fractures in both groups healed with a healing time of 3 to 6 months.At the last follow-up,the Merle d'Aubign-Postel score of the 3D printed group was lower than that of the conven-tional group(P＜0.05),with no significant differences in walking ability,hip mobility and total score(P＞0.05).In 3D printing group,6 cases were excellent,5 cases were good,3 cases were fair;in conventional group,5 cases were excellent,5 cases were good,4 cases were fair,1 case was worse;no significant difference between two groups(P＞0.05).Conclusion Virtual preopera-tive planning and 3D-printed templates for pre-contoured plates can reduce operative time and the blood loss of surgery,im-prove the quality of reduction.This method is efficient,accurate and reliable to treat acetabular posterior wall fractures.

Objective To explore clnical efficacy of modified Frosch approach for Schatzker type Ⅱ tibial plateau fracture with posterolateral column.Methods From January 2019 to September 2020,totally 11 patients with Schatzker type Ⅱ tibial plateau fractures with posterolateral column were treated,including 7 males and 4 females,aged from 21 to 49 years old.Modi-fied Frosch approach was adopted for lateral decubitus position,and posterolateral fractures were fixed with support plates or posterolateral screws.Anterolateral fixation with conventional tibial plateau lateral locking plate.Tibial plateau varus angle and posterior inclination angle were measured by X-ray immediately and 12 months after operation,as well as knee motion at 12 months after operation.Knee function at 12 months after operation was evaluated by knee score of Hospital for Special Surgery(HSS).Results Eleven patients were followed up for 12 to 15 months.Varus angle and inclination angle at immediately after operation ranged from 76° to 86° and 6° to 10°,respectively,and 79° to 88° and 6° to 10°,respectively at 12 months after op-eration.The range of extension of knee ranged from 0° to 5°,and flexion was 106° to 137° at 12 months after operation.Post-operative HSS knee score at 12 months ranged from 74 to 94 scores,8 patients were excellent and 3 good.Conclusion Modi-fied Frosch approach is an effective surgical method for Schatzker type Ⅱ tibial plateau fracture with posterolateral column.A single incision is used to complete fracture exposure and fixation at two sites,avoiding use of combined incisions,and could ob-tain good postoperative knee joint function.During operation,popliteal fossa structure should be familiar,and the common per-oneal nerve should be protected to avoid injury.

Objective:To evaluate the clinical and prognostic value of prothrombin time(PT)and activated partial thromboplastin time(APTT)in newly diagnosed patients with multiple myeloma(MM).Methods:The clinical data of 116 newly diagnosed MM patients in the Second Hospital and Third Hospital of Shanxi Medical University from October 2014 to March 2022 were analyzed retrospectively,and the patients were divided into two groups:normal PT and APTT group and prolonged PT or APTT group.The differences in sex,age,classification,staging,bleeding events,laboratory indicators[including hemoglobin(Hb),platelet count(PLT),serum calcium,serum albumin(ALB),lactate dehydrogenase(LDH),serum creatinine and β 2-microglobulin],and cytogenetic characteristics between the two groups of patients were compared.The effect of prolonged PT or APTT on survival of patients with MM was analyzed.Results:Compared with patients in normal PT and APTT group,patients in prolonged PT or APTT group were more likely to experience bleeding events(x2=5.087,P=0.024),with lower ALB levels(x2=4.962,P=0.026)and PLT levels(x2=4.309,P=0.038),and higher serum calcium levels(x2=5.056,P=0.025).The positive rates of del17p,del13q and 1q21+in prolonged PT or APTT group were higher than those in normal PT and APTT group,but the difference was not statistically significant(P＞0.05).K-M survival analysis showed that the prolonged PT or APTT group had a shorter median progression-free survival(PFS)(P=0.032)and overall survival(OS)(P=0.032).Multivariate Cox analysis showed that prolonged PT or APTT(HR=2.1 16,95％CI:1.025-4.372,P=0.043)and age ≥65 years(HR=2.403,95％CI:1.195-4.836,P=0.014)were independent risk factor for OS in newly diagnosed MM patients.However,prolonged PT or APTT had no significant effect on PFS of newly diagnosed MM patients(HR=1.162,95％CI:0.666-2.026,P=0.597).Conclusion:Newly diagnosed MM patients with prolonged PT or APTT have worse clinical indicators,shorter PFS and OS.Prolonged PT or APTT is an independent risk factor for OS in MM patients.

Objective:To investigate the clinical characteristics and survival analysis of myelodysplastic syndromes(MDS)with RUNX1 gene mutation.Methods:Clinical data of 177 newly diagnosed MDS patients admitted to the Department of Hematology,the Second Affiliated Hospital of Air Force Military Medical University from October 1,2015 to October 31,2022 were retrospectively analyzed.Gene mutation detection was performed by second-generation sequencing technology,and clinical characteristics and prognosis of patients with RUNX1 gene mutation were analyzed.Results:A total of 30 cases(16.95％)of RUNX1 gene mutations were detected,including 15 missense mutations(50.0％),9 frameshift deletion mutations(30.0％),4 splice site mutations(13.3％),1 insertion mutation(3.3％),and 1 nonsense mutation(3.3％).Patients with RUNX1 mutations had a median age of 68.5 years at diagnosis(range:62.25-78.50 years old).There were no significantly differences between RUNX1 mutations and wild type patients in age distribution,gender,peripheral blood white blood cell count,hemoglobin level,bone marrow and peripheral blood blasts ratio,IPSS-R cytogenetics,IPSS-R stage,etc.(P＞0.05).However,there were statistically significant differences in platelet count and whether complicated karyotype.Compared with patients without RUNX1 gene mutation,patients with RUNX1 gene mutation had lower platelet count(P=0.018),and were less likely to have complicated karyotype at initial diagnosis(P=0.01).Cox proportional hazards model analysis showed that when other co variates remained unchanged,the higher the platelet count,the better the survival of patients(HR=0.995,95％CI:0.990-0.999,P=0.036);In the IPSS-M prognostic stratification,keeping other covariates unchanged,the risk of progression or death of myelodysplastic syndrome was significantly lower in the medium to high-risk and low-risk groups compared with the high-risk group(HR=0.149,95％CI:0.031-0.721,P=0.018;HR=0.026,95％CI:0.003-0.234,P=0.001).Survival analysis showed that MDS patients with RUNX1 gene mutation had worse overall survival time(P＜0.001).Patients with RUNX1 mutation had worse OS than non-mutation patients in the early WHO group.RUNX1 mutation and IPSS-M risk stratification mean OS and mean LFS were worse in low-risk patients than in non-mutated patients.Conclusion:RUNX1 gene mutation is an adverse prognostic factor in MDS patients,especially in the IPSS-M prognosis stratification group of low-risk,medium-low risk,medium-high risk and WHO classification of early patients.
