According to the Qi-blood-body fluid theory and the association between the spleen in visceral manifestation theory of traditional Chinese medicine （TCM） and mitochondria in modern cellular biology， it is proposed that the role of the spleen in generating and transforming Qi and blood is analogous to the energy-producing function of mitochondria—both serving as fundamental power sources for vital activities of the human body. The spleen governs transportation and transformation， playing a critical role in energy metabolism and the digestion and absorption of nutrients. Similarly， mitochondria are vital for maintaining physiological functions such as cellular energy supply， cell survival， and overall human metabolism. Furthermore， spleen deficiency is closely linked to mitochondrial dysfunction. Accordingly， mitochondrial energy conversion and substance metabolism are regarded as the microscopic essence of the spleen's function in transportation and transformation. Spleen deficiency and mitochondrial dysfunction contribute to the formation of pathological products such as phlegm-turbidity and blood stasis. This aligns with the pathogenesis of chronic obstructive pulmonary disease （COPD）， with Qi deficiency as the root cause and phlegm-turbidity and blood stasis as the manifestations. Therefore， the integrative treatment of COPD should follow the therapeutic principle of invigorating the spleen and reinforcing healthy Qi， while also resolving phlegm and removing blood stasis to address both root cause and manifestations. This approach can improve the mitochondrial function， regulate energy metabolism， and reduce oxidative stress levels to alleviate COPD symptoms， slow down disease progression， and improve prognosis. By integrating the holistic concept of TCM with molecular mechanisms of modern medicine， this paper explores the pathogenesis and therapeutic principles of COPD from the spleen-mitochondria correlation. It not only provides a new direction for the modern development of TCM and the integration of Chinese and Western medicine but also offers a theoretical foundation for the integrated treatment of chronic， complex age-related diseases.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the risk factors and outcomes of poor graft function (PGF) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with transfusion dependent thalassemia (TDT).Methods:A retrospective cohort study was conducted in 118 pediatric TDT patients who underwent allo-HSCT at the First Affiliated Hospital of Guangxi Medical University from June 30, 2018 to December 31, 2022. Based on PGF diagnostic criteria, patients were categorized into PGF group and good graft function (GGF) group. Clinical features, including pre-transplant baseline characteristics and post-transplant complications were compared between groups by χ2 test or Fisher exact test. Logistic regression identified PGF risk factors and model performance was assessed by receiver operating characteristic (ROC) curve analysis. Survival analysis was conducted using the Kaplan-Meier method with Log-Rank test. Results:Among 118 patients, there were 69 males (58.5%) and 49 females (41.5%). Fifteen cases (12.7%) developed PGF while 103 cases (87.3%) achieved GGF. Compared to the GGF group, the PGF group had significantly higher rates of age ≥10 years at transplant, interval from diagnosis to transplant ≥6.7 years, human leukocyte antigen (HLA) mismatch, ABO mismatch, post-transplant BK virus infection, and hemorrhagic cystitis (all P<0.05). Multivariate analysis identified independent risk factors for PGF: age ≥10 years at transplant ( OR=27.20, 95% CI 2.11-350.91), interval from diagnosis to transplant ≥6.7 years ( OR=23.23, 95% CI 1.39-388.23), post-transplant cytomegalovirus (CMV) infection ( OR=57.83, 95% CI 3.01-1 111.71), and post-transplant BK virus infection ( OR=67.73, 95% CI 2.56-1 794.52). The ROC curve showed an area under curve of 0.92 (95% CI 0.86-0.97, P<0.001). The 4-year overall survival rate was significantly lower in the PGF group compared to the GGF group ((53.3±12.9)% vs.(90.2±2.9)% ,χ2=16.49, P<0.001). Conclusions:Risk factors for PGF in TDT children after allo-HSCT include age ≥10 years at transplant, interval from diagnosis to transplant ≥6.7 years, post-transplant CMV infection and post-transplant BK virus infection. The PGF patients after allo-HSCT exhibit significantly poorer overall survival compared to those with GGF.

Objective:To study the dosimetric characteristics of the Avoidance Sectors function in the Eclipse planning system in the design of volumetric intensity-modulated arc radiotherapy(VMAT)plan for non-small cell lung cancer(NSCLC).Methods:The case data of 20 NSCLC patients who admitted to Hunan Provincial Cancer Hospital in 2024 were retrospectively selected,both free avoidance sectors volumetric(FASV)modulated arc therapy and avoidance sectors volumetric(ASV)modulated arc therapy were formulated for all patients.The dose parameters and the total number of machine unit(MU)of accelerator of the target area and organs at risk between two kinds of plans were compared.The correlation between the ratio(VPTV/Vlung)of planning target volume(PTV)to whole lung volume and the exposure dosimetry index of whole lung were further analyzed.Results:Comparative result between FASV plan and ASV plan indicated that the conformity index(CI)of the FASV plan was(0.83±0.07),which was better than that of the ASV plan(0.78±0.06),and the difference was significant(t=2.086,P<0.05).The V5 value(48.35±7.28)%of the whole lung in the ASV plan was significantly lower than that(57.68±6.63)%in the FASV plan(t=3.670,P<0.05).There were not statistically significant differences in the V20,V30 and mean dose(Dmean)of the whole lung and heart between two kinds of plans(P>0.05).There were not statistically significant differences in the maximum doses of the spinal cord and esophagus between two kinds of plans(P>0.05).The total MU value(444.8±78.9)of the ASV plan was less than that(518.27±70.9)of the FASV plan(t=2.682,P<0.05).The results of Pearson correlation analysis indicated that the correlative values between VPTV/Vlung and V20,V30,and Dmean of whole lung were respectively r=0.756,0.697,and 0.732 in FASV plan(P<0.05).Conclusion:For NSCLC patients,the ASV plan can effectively reduce V5 value of lung tissue,and decrease the total MU value of accelerator's irradiation.The avoidance sectors function is worthy of recommendation.In FASV plan,the VPTV/Vlung value appeared a positive correlation with whole lung V20,V30,and Dmean.It is very necessary to adopt individual management strategies for respiratory motion in reducing the irradiation range of target area.

[Purpose]To analyze the prevalence characteristics and disease burden of lung cancer in Hebei cancer registration areas from 2012 to 2020.[Methods]Lung cancer data were collected from the Hebei Provincial Cancer Registry from 2012 to 2020.The crude incidence/mortality rates,age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC)and by world standard population(ASIRW/ASMRW)were calculated.The Joinpoint model was used to calculate the annual percentage change(APC)and average annual percentage change(AAPC).Years of life lost(YLL)and years lived with disability(YLD)and the disability-adjusted life years(DALY)were calculated.[Results]From 2012 to 2020,the ASIRW of lung cancer in Hebei can-cer registration areas was 33.13/105,44.56/105 for men and 22.54/105 for women,respectively;the incidence rates of urban and rural areas were 29.05/105 and 33.52/105,respectively.The incidence rates increased with ages,reaching a peak in the age group of 80～84 years old.There was a de-creasing trend in the ASIRW of lung cancer(AAPC=-3.99％,P＜0.05).From 2012 to 2020,the ASMRW of lung cancer was 25.80/105,36.56/105 for men and 15.96/105 for women,respectively;the mortality rates of urban and rural areas were 25.14/105 and 26.12/105,respectively.The mor-tality rates increase with ages,reaching a peak in the age group of 85 and above years old.There was a decreasing trend in the mortality of lung cancer(AAPC=-4.65％,P＜0.001)from 2012 to 2020.The DALY of lung cancer in Hebei Province from 2012 to 2020 was 484 194 person-years,with male accounting for 66.77％,female accounted for 33.23％,the DALY rate of lung cancer was 3.31‰,of which 35.57％in urban areas and 64.43％in rural areas.[Conclusion]Lung can-cer incidence and mortality rate in Hebei cancer registration areas from 2012 to 2020 showed a decreasing trend.The disease burden is gradually increasing with age in middle-aged and el-derly population.

Objective:To identify the risk factors for acute graft-versus-host disease (aGVHD) in patients with acute myeloid leukemia (AML) undergoing haploidentical hematopoietic stem cell transplantation (HID-HSCT) .Methods:A total of 141 AML patients who underwent HID-HSCT at the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences, from January 2020 to July 2021 were included. The cumulative incidence of aGVHD was analyzed using the Fine-Gray competing risk model, with relapse and death as competing events, to compare differences between groups. Potential risk factors were evaluated by univariable and multivariable Cox proportional hazards regression analyses to determine their independent effects on aGVHD.Results:Among the 141 patients, 86 (61.0%) were male and 55 (39.0%) were female, with a median age at transplantation of 34 years. Within 100 days post-transplant, 59 patients developed grade Ⅱ-Ⅳ aGVHD, whereas 86 patients experienced no or grade Ⅰ aGVHD (the grade 0-Ⅰ aGVHD group) . Survival analysis showed that the 3-year overall survival was 68.7% (95% CI: 57.7%-81.9%) in the grade Ⅱ-Ⅳ aGVHD group, compared with 78.8% (95% CI: 70.4%-88.3%) in the grade 0 - Ⅰ aGVHD group, with the difference not being statistically significant ( P=0.190) . Univariable analysis identified donor age ( P=0.020, HR=1.020, 95% CI: 1.000-1.040) and the female donor-male recipient sex combination ( P=0.033, HR=1.980, 95% CI: 1.160-3.380) as risk factors for grade Ⅱ-Ⅳ aGVHD. Multivariable analysis confirmed that donor age ( P=0.005, HR=1.026, 95% CI: 1.008-1.047) and the female donor-male recipient sex combination ( P=0.002, HR=2.339, 95% CI: 1.354-4.037) were independent risk factors for aGVHD. Patients receiving grafts from donors aged >45 years had a significantly higher 100-day cumulative incidence of grade Ⅱ-Ⅳ aGVHD compared with those receiving grafts from donors ≤45 years [54.7% (95% CI: 42.3%-67.0%) vs 31.6% (95% CI: 21.0%-42.1%) , P=0.006]. Similarly, patients with the female donor-male recipient sex combination had a higher 100-day cumulative incidence of grade Ⅱ-Ⅳ aGVHD than those with other sex combinations [56.8% (95% CI: 40.4%-73.1%) vs 36.9% (95% CI: 27.5%-46.3%) , P=0.015]. Conclusion:Older donor age and the female donor-male recipient sex combination remain independent risk factors for aGVHD in patients with AML undergoing HID-HSCT.

Objective:To investigate genetic findings and pregnancy outcomes in fetuses with omphalocele.Methods:This retrospective study analyzed data from 502 fetuses with prenatally diagnosed omphalocele who underwent genetic testing at Guangzhou Women and Children's Medical Center and Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region between January 2014 and March 2024. Testing methods included karyotyping, chromosomal microarray analysis (CMA), methylation-specific multiplex ligation-dependent probe amplification, and whole-exome sequencing (WES). Cases were categorized as non-isolated ( n=340) or isolated ( n=162) based on ultrasound findings. Differences in genetic abnormality detection rates and pregnancy outcomes were analyzed using Mann-Whitney U test, independent samples t-test, and Chi-square test (or Fisher's exact test). Results:Among 502 fetuses, karyotyping plus CMA detected chromosomal abnormalities in 223 cases (44.4%, 223/502), including trisomy 18 (57.0%, 127/223) and trisomy 13 (23.3%, 52/223). CMA additionally identified nine pathogenic copy number variations (1.8%, 9/502) and five uniparental disomies (1.0%, 5/502), increasing the total diagnostic yield from 44.4% to 47.2%. The genetic abnormality rate was significantly lower in isolated (14.8%, 24/162) versus non-isolated omphalocele (64.7%, 220/340) ( χ2=109.34, P<0.001). WES detected variants in nine of 16 karyotype/CMA-negative cases, including five pathogenic variants involving PIK3CA and CDKN1C. Eight imprinting disorders (1.6%, 8/502) were identified, including five Beckwith-Wiedemann syndrome cases. Among 499 cases with follow-up, 401 (80.4%, 401/499) underwent pregnancy termination. Live birth rate was higher in isolated versus non-isolated groups [42.5% (69/162) vs. 8.5% (29/340), χ2=77.67, P<0.001]. Three cases were lost to follow-up. The one-year survival rate was 93.9% (92/98) in live-born infants. Conclusion:Aneuploidy (particularly trisomy 18) is the primary genetic etiology of omphalocele. CMA and WES significantly improve diagnostic yield. Isolated omphalocele has a more favorable prognosis, while non-isolated cases show significantly higher genetic abnormality rates. A stratified testing strategy is recommended: karyotyping plus CMA for isolated cases and prioritization of WES for multiple anomalies.
