Objective: To investigate the impact of preschool children s aquatic motor skill (AMS) acquisition on their fundamental motor skill (FMS) development and the correlation between AMS and FMS development, so ao to provide a scientific basis for early childhood education and physical education teaching. Methods: From April to June 2024, 60 children, recruited by random sampling from a kindergarten in Taiyuan, were stratified randomly divided into an experimental group ( n =30) and a control group ( n =30). The experimental group were further divided into five classes of six each. They received AMS practice interventions twice weekly, 40 minutes per session, over eight weeks (16 sessions total) at a designated swimming center. The control group maintained their usual routine. Children s FMS and AMS were assessed pre and post intervention using the Test of Gross Motor Development-3rd (TGMD3) and Actual Aquatic Skills Test (AAST), respectively. Before and after test comparisons within and between groups employed t-tests, Wilcoxon signedrank tests, ANCOVA (including ranktransformed ANCOVA), and Cohen s d effect sizes were calculated for standardized mean differences. Spearman rank correlation was used to analyze relationships between FMS and AMS. Results: After the aquatic learning, the experimental group scored significantly higher than the control group on locomotor skills ( F=20.47, P <0.01, η 2=0.26), FMS ( F=4.59, P =0.04, η 2=0.08), and AMS ( F=109.71, P<0.01, η 2=0.79). The experimental groups improvement in locomotor skills 5.0(3.8, 7.3) versus the control group (2.8±2.5) yielded a medium effect size (Cohen s d =0.71); AMS gains in the experimental group [26.0(20.8, 28.0)] versus controls [1.0(0, 2.3)] showed a very large effect size (Cohen s d =4.73) (both P <0.01). Among preschool children, AMS acquisition was positively correlated with locomotor skills ( r =0.39) and overall FMS ( r =0.43)(both P <0.05). Skill specific assessments revealed lower proficiency in headfirst entry (immersion), treading water, and sagittalplane rotation. Conclusion Preschool children s acquisition of AMS has a positive effect on their FMS, with mutual facilitation between the two, especially in locomotor abilities.

OBJECTIVE: To evaluate the effectiveness of combined anterolateral thigh-ilioinguinal Flow-through flaps for repairing complex lower limb defects. METHODS: A clinical data of 20 patients with complex lower limb injuries admitted between January 2018 and January 2024 was retrospectively analyzed. The cohort included 14 males and 6 females with an average age of 47.3 years (range, 29-65 years). Injury mechanisms comprised heavy-object trauma (n=7), traffic accidents (n=5), machinery crush injuries (n=5), and osteomyelitis (n=3). Defects involved the left (n=7) and right (n=13) limbs, with anatomical distributions including tibiofibular injuries (n=6), isolated tibial injuries (n=6), foot and ankle injuries (n=5), and femoral-tibial injuries (n=3). The size of soft tissue defects ranged from 23 cm×8 cm to 44 cm×12 cm. Reconstruction employed combined anterolateral thigh-ilioinguinal Flow-through flaps in the size of 24 cm×10 cm to 48 cm×14 cm. The recipient sites were sutured in primary closure in 12 cases, and 8 cases had no available vascular anastomosis sites in the recipient sites, and a cross-leg flap form was used to establish a temporary blood supply, and the flaps were cut off after 3-4 weeks. The donor sites in the thigh were directly sutured. During follow-up, the survival of the flaps, appearance, texture, and related complications were observed; the Vancouver scar scale (VSS) score was used to evaluate the scar condition of the flaps, the lower extremity function scale (LEFS) score was used to evaluate the function of the affected lower limb, and the visual analogue scale (VAS) score was used to evaluate the pain condition of the affected side. RESULTS: Postoperatively, the flap complete necrosis occurred in 1 case, marginal necrosis in 1 case, superficial infections in 2 cases, and venous thrombosis in 1 case. The remaining flaps survived completely with primary wound healing at both recipient and donor sites. Limb salvage was achieved in all patients. All patients were followed up with 12-24 months (mean, 18.4 months). All flaps had satisfactory color, texture, and contour. Fractures reached clinical union in all cases. Donor site morbidity included mild contralateral hip flexion/knee extension limitation (n=1), persistent hypoesthesia (n=3), and chronic pain (n=1) at 6 months. At 12 months after operation, the LEFS, VSS, and VAS scores on the affected side were 62.7±4.6, 3.5±1.1, and 1.2±0.6, respectively, which were superior to those at 1 month after operation (38.6±2.8, 8.5±1.4, 4.7±1.1), and the differences were significant (P<0.05). CONCLUSION The anterolateral thigh-ilioinguinal Flow-through flaps for repairing complex lower limb injuries is a good method. The distal blood supply of the affected side recover well, the survival rate of the flap is high, and the function recovery of the affected limb is good.

Ferroptosis, a regulated cell death process distinct from apoptosis, is characterized by iron dysregulation and reactive oxygen species (ROS) accumulation. After intracerebral hemorrhage (ICH), decreased cerebral blood flow and iron released from erythrocytes trigger lipid peroxidation-particularly of polyunsaturated fatty acids (PUFAs)-through a cascade of reactions in local brain tissues, promoting ferroptosis. Mitochondrial dysfunction and neuroinflammation further elevate ROS, exacerbating lipid peroxidation and accelerating neuronal ferroptosis. Thus, PUFA peroxidation and associated metabolic pathways play a critical role in ICH-related neuronal damage. This review summarizes current understanding of how PUFA peroxidation contributes to ferro-ptosis after ICH, discusses key regulatory mechanisms involving lipid and iron metabolism, and highlights potential therapeutic strategies targeting ferroptosis to improve neurological outcomes.

There were 8 males and 3 females, with an age of 49.91±18.81 years (range, 15-75 years). Tile classification: 1 case of B1 type, 7 cases of B2 type, and 3 cases of C1 type. Among them, there were 10 cases of anterior ring injury, 9 cases of posterior ring injury, 1 case of pubic symphysis separation, and 4 cases of iliac bone fracture. The time from injury to surgery was 3.36±1.32 d (range, 2-7 d). Record the effective fluoroscopy times during the operation, single screw insertion time, operation time, blood loss, and relevant data during postoperative follow-up (including fracture reduction quality, fracture healing time, postoperative functional recovery, and complications). The Matta imaging scoring criteria were used to evaluate the quality of fracture reduction, and the Majeed scoring system was used to assess postoperative pelvic function.Results:All 11 patients successfully completed the surgery, with a duration of 115±5 min (range, 85-185 min); single screw insertion time 6.09±2.02 min (range, 3-11 min); the effective fluoroscopy frequency was 8.56±4.98 times (range, 4-20 times); the intraoperative blood loss was 20.45±12.74 ml (range, 10-50 ml). Three cases were fixed using an internal fixation system (INFIX), seven cases were fixed using anterior ring channel screws, eight cases were fixed using sacroiliac screws, and four cases were fixed using LC-II screws. All patients were followed up for 6.82±3.25 months (range, 6-12 months), and the fracture healing time was 4.36±1.12 months (range, 3-6 months). There were no complications such as internal fixation fracture, screw loosening or retraction, infection, nerve injury, or active bleeding. According to the Matta imaging reduction evaluation criteria, the results were excellent in 6 cases, good in 4 cases, and fair in 1 case. At the last follow-up, the Majeed score was 94.36±5.63 points (range, 83-99 points). The results showed that 9 cases were excellent, 2 cases were good.Conclusions:The intelligent visualization system and pelvic unlocking reduction frame assist in the treatment of unstable pelvic fractures, which have the advantage of visualizing the surgical process, improving the reduction efficiency and precise insertion rate of channel screws, with minimal trauma, less bleeding, low infection rate, fast postoperative recovery, and reduced radiation exposure risk for both doctors and patients.
