Objective: To explore the effects of 8week highintensity interval training on body shape and adipokines of obese male college students, so as to provide practical reference for weight loss of obese college students. Methods: A total of 30 male college students [age (20.10±0.55)years] with body mass index (BMI) ≥28 kg/m2 were recruited in March 2022 at China University of Petroleum (East China). The 8week highintensity interval training (HIIT) intervention was conducted from 11 April to 10 June 2022, 3 times a week (Monday, Wednesday, Friday), each time for 16:30-17:30. Body composition and adipokine levels were assessed before and after the intervention. All indicators were compared by pairedsamples ttests and single factor repeated measurement analysis of variance before and after intervention, and Pearson correlation analyses were used to test for associations between variables. Results: After 8 weeks of intervention, BMI, waist circumference and body fat of obese male college students decreased from (31.36±4.41)kg/m2, (107.52±9.66)cm and (28.04±5.79)kg to (30.40±4.37)kg/m2, (100.67±8.29)cm and (22.56±5.22)kg, respectively (t=3.84, 8.02, 9.29). Fatfree body mass index increased from (70.19±5.54)kg/m2 to (75.34±5.25)kg/m2 (t=-8.65) (P<0.01). There were statistically significant differences in the levels of Leptin, Adiponectin, and Irisin before intervention, at week 4 and at week 8 (F=26.05, 35.62, 4.95, P<0.05). There was no statistically significant difference in the content of reticulin (F=3.62, P>0.05). Conclusions The 8week of HIIT can effectively improve body shape of obese male college students and affect the effects of adipokines in the body. HIIT can be added to sports exercise to improve the health status of obese college students.

Primary ciliary dyskinesia (PCD) is a congenital, motile ciliopathy with pleiotropic symptoms. Although nearly 50 causative genes have been identified, they only account for approximately 70% of definitive PCD cases. Dynein axonemal heavy chain 10 (DNAH10) encodes a subunit of the inner arm dynein heavy chain in motile cilia and sperm flagella. Based on the common axoneme structure of motile cilia and sperm flagella, DNAH10 variants are likely to cause PCD. Using exome sequencing, we identified a novel DNAH10 homozygous variant (c.589C > T, p.R197W) in a patient with PCD from a consanguineous family. The patient manifested sinusitis, bronchiectasis, situs inversus, and asthenoteratozoospermia. Immunostaining analysis showed the absence of DNAH10 and DNALI1 in the respiratory cilia, and transmission electron microscopy revealed strikingly disordered axoneme 9+2 architecture and inner dynein arm defects in the respiratory cilia and sperm flagella. Subsequently, animal models of Dnah10-knockin mice harboring missense variants and Dnah10-knockout mice recapitulated the phenotypes of PCD, including chronic respiratory infection, male infertility, and hydrocephalus. To the best of our knowledge, this study is the first to report DNAH10 deficiency related to PCD in human and mouse models, which suggests that DNAH10 recessive mutation is causative of PCD.
