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.

Objective To compare the clinical efficacy, safety, and patient’ prognosis of catheter-directed thrombolysis (CDT) via anterior tibial vein and popliteal vein approaches in the treatment of acute lower extremity deep vein thrombosis (DVT). Methods A retrospective analysis was conducted on the clinical data of 195 patients diagnosed with acute mixed lower extremity DVT and treated with CDT in the Department of Interventional and Vascular Surgery, Affiliated Hospital of Nantong University from January 2020 to December 2023. Patients were divided into an observation group (anterior tibial vein approach, n=97) and a control group (popliteal vein approach, n=98) according to the puncture route. Baseline data, thrombolysis-related indices (urokinase dosage, coagulation function indices), efficacy measures (degree of thrombus dissolution, leg circumference difference, visual analogue scale [VAS] score, venous clinical severity score [VCSS]), recovery parameters (time to ambulation, length of hospital stay), complication rates, and long-term prognosis measures (Villalta score, incidence of post-thrombotic syndrome [PTS]) were compared between the two groups. Results There was no statistically significant difference in urokinase dosage and levels of coagulation function indices between the two groups. Postoperatively, the leg circumference difference at 15 cm below the knee, VAS score, and VCSS score were significantly lower in the observation group than in the control group (P=0.001). The observation group had higher grade Ⅲ dissolution rates in the popliteal and anterior tibial veins compared to the control group (P<0.05), while differences of dissolution rates in the iliac and femoral veins were not statistically significant. The observation group had shorter length of hospital stay and earlier ambulation times than the control group (P=0.001). There were no significant differences in complication rates, Villalta scores, or PTS incidence between the two groups. Conclusions CDT via the anterior tibial vein puncture approach for acute mixed lower extremity DVT is superior to the popliteal vein approach in promoting resolution of lower extremity swelling, alleviating pain, improving venous clinical symptoms, and achieving higher thrombus dissolution rates in the popliteal and anterior tibial veins. It also enables faster recovery and demonstrates good safety.

Objective:
To analyze the relationship between body mass index(BMI) during pre pregnancy, maternal lipid levels during early pregnancy and childhood overweight and obesity, as well as the mediating role of maternal lipid levels during early pregnancy in pre pregnancy BMI and childhood overweight and obesity, providing scientific evidence for developing obesity prevention strategies in preschool children.
Methods:
Using data from Peking University Birth Cohort in Tongzhou (PKUBC-T) collected between June 2018 and September 2022, the study included 1 292 mother-child pairs. Participants were stratified into two groups based on children s BMI Z scores at age 3: an overweight/obesity risk group (BMI Z >1, n =173) and a non overweight/obesity risk group (BMI Z ≤1, n =1 119).Multivariate Logistic regression was conducted to analyze the associations between pre pregnancy BMI, maternal lipid levels[total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),TC/HDL-C,TG/HDL-C,LDL-C/HDL-C] during early pregnancy and childhood overweight and obesity. The mediating effect of maternal lipid levels during early pregnancy on pre pregnancy BMI and childhood overweight and obesity was further explored.
Results:
There were statistically significant differences in pregnancy BMI levels, early pregnancy blood LDL-C ,TC/HDL-C,LDL-C/HDL-C levels between the overweight and obesity risk group and the non overweight and obesity risk group ( χ 2/Z =19.01, 2.48, 2.48, 2.71, all P <0.05). Multivariate Logistic regression analysis showed that pre pregnancy BMI, LDL-C, TC/HDL-C and LDL-C/HDL-C in early pregnancy were significantly associated with childhood overweight and obesity ( OR =1.09, 1.42, 1.49, 1.60, all P <0.05). LDL-C, TC/HDL-C and LDL-C/HDL-C in early pregnancy played a significant mediating role on pre pregnancy BMI and childhood obesity and the mediating effects accounted for 7.3%, 10.2%, 23.5% of the total effects, respectively (all P <0.05).
Conclusions
Maternal hyperlipidemia during early pregnancy partially mediated the association between pre pregnancy obesity and childhood obesity. Both pre pregnancy obesity and maternal hyperlipidemia during early pregnancy are risk factors for obesity in preschool children.

Objective To compare the efficacy of modified radiofrequency ablation (RFA) combined with sclerosing agent injection and high stripping and ligation (HSL) combined with sclerosing agent injection in the treatment of great saphenous vein varicosity. Methods A total of 220 patients (252 affected limbs) who underwent surgery for great saphenous vein varicosity at Affiliated Hospital of Nantong University from May 2022 to March 2024 were selected. They were divided into RFA group (110 patients and 125 affected limbs treated with modified RFA combined with sclerosing agent injection) and HSL group (110 patients and 127 affected limbs treated with HSL combined with sclerosing agent injection) according to the surgical methods. The treatment effect, surgical time, bleeding during the surgery, time to get out of bed after surgery, and various postoperative complications were compared between the two groups. The pain level, disease severity, and the quality of life were measured using the visual analog scale (VAS), venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire-14 item (CIVIQ-14), respectively. Results There was no statistically significant difference in the total effective rate between the two groups of patients, but the distribution of efficacy levels in the RFA group was better than that in the HSL group (P=0.044). Compared with the HSL group, the RFA group had shorter surgery time, fewer incisions during surgery, less bleeding during the surgical process, shorter time to get out of bed after surgery(P<0.01), and a lower overall complication rate (P=0.006). The RFA group had lower postoperative VAS, VCSS, and CIVIQ-14 scores than the HSL group 1 month after surgery (P<0.01). During 6 months of postoperative follow-up, the recurrence rates were similar between the two groups. Conclusions Compared with HSL combined with sclerosing agent injection, the modified RFA combined with sclerosing agent injection for the great saphenous vein varicosity has the advantages of less trauma, faster recovery, fewer complications, better postoperative quality of life, and is worthy of clinical promotion and application.
