Objective:To analyze the validity of an enhanced nutrition management model for all pregnant women in reducing the incidence of macrosomia.Methods:This retrospective cohort study utilized data from the Beijing Birth Cohort database established by Beijing Obstetrics and Gynecology Hospital, Capital Medical University. A total of 73 193 pregnant women who underwent regular prenatal examinations and delivered at the hospital between January 2018 and December 2023 were consecutively included. From 2018 to 2020, all participants received nutrition education, and high-risk pregnancies predisposed to macrosomia were referred to nutrition clinics for further follow-up. From 2021 to 2023, obstetricians participated in nutritional assessments and gestational weight gain guidance, with repeated nutrition evaluations and education provided during early, mid, and late pregnancy. A multidisciplinary team (obstetrics and nutrition departments) collaborated to implement an enhanced nutrition management model for all pregnant women. General data, parity, gestational age at delivery, neonatal birth weight, and clinical information were collected. Annual incidences of macrosomia and low birth weight were calculated. Chi-square tests and variance analysis were used to analyzed yearly changes in macrosomia rates and evaluate the impact of the two-phase management strategies on macrosomia incidence, thereby to explore the validity of an enhanced nutrition management model for all pregnant women in reducing the incidence of macrosomia.Results:The number of deliveries included annually from 2018 to 2023 was 14 578, 15 413, 11 496, 11 146, 10 396, and 10 164, respectively. Maternal pre-pregnancy body mass indices in 2022 to 2023 were higher than those in 2018 to 2021 [(22.26±3.50) and (22.23±3.65) vs (21.87±3.27), (21.82±3.31), (21.86±3.34) and (21.94±3.39) kg/m2, respectively (all P<0.05)]. Neonatal birth weights in 2021 to 2022 were lower than those in 2018 to 2020 [(3 271±514) and (3 270±513) vs (3 323±504), (3 314±500), and (3 315±510) g], and the birth weight in 2023 was further reduced compared to that in 2018 to 2022 [(3 236±506) vs (3 323±504), (3 314±500), (3 315±510), (3 271±514) and (3 270±513) g] (all P<0.05). The incidence of macrosomia in 2021 to 2022 was lower than those in 2018 to 2020 (5.55%, 5.75% vs 6.97%, 6.68%, 6.67%), and the incidence in 2023 further decreased compared to those in 2018 to 2022 (4.16% vs 6.97%, 6.68%, 6.67%, 5.55%, 5.75%) (all P<0.05). Conclusion:The enhanced nutrition management model for all pregnant women effectively reduces the incidence of macrosomia, demonstrating significant clinical value for widespread implementation.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

Objective: The aim of the study was to investigate the association of outdoor physical activity and insomnia symptoms with depressive symptoms in college students, so as to provide a theoretical basis for preventing and improving depression of the college students. Methods: A sample survey of 9 349 college students from 4 colleges and universities in 3 provinces in Hubei, Jiangxi and Chongqing were conducted from November to December 2021. The Patient Health Questionnaire, Insomnia Severity Index and outdoor physical activity questionnaire were used to evaluate the depressive symptoms, insomnia symptoms and outdoor activities of college students, respectively. The χ 2 test was used to compare the difference of the positive rate of depressive symptoms in college students. Logistic regression analysis was used to analyze the association between outdoor physical activity, insomnia symptoms and depressive symptoms. Generalized linear model was used to analyze the association of interaction effect of outdoor activity and insomnia symptoms with depressive symptoms. Results: The detection rate of depressive symptoms in college students was 37.4%. Significant differences in the detection rate of depressive symptoms were observed among college students with different majors, nationalities,educational backgrounds, family residence, family type, family economic conditions, study burden, number of friends, father s education level,mother s education level( P <0.05). Logistic regression analysis showed that outdoor physical activity ( OR=0.51-0.69, P <0.01) and insomnia symptoms ( OR=6.15-21.30, P <0.01) were associated with depressive symptoms( P <0.01). Generalized linear model showed that insomnia symptoms( B =0.57), outdoor physical activity ( B =-0.15) and their interaction terms ( B =-0.02) were associated with college students depression( P <0.05). Conclusion This study suggests that insufficient time for outdoor physical activity and insomnia symptoms may increase the risk of depressive symptoms in college students. College students with insufficient time for outdoor physical activity and insomnia have a higher risk of developing depressive symptoms.

Objective:To evaluate the role of glutathione S-transferase μ1 (GSTM1) expression in mild hypothermia-induced mitigation of cerebral ischemia-reperfusion (I/R) injury and the relationship with microglial polarization.Methods:Eighty clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 260-280 g, were divided into 4 groups ( n=20 each) using a random number table method: sham operation group (S group), cerebral I/R group (I/R group), mild hypothermia group (H group), and GSTM1 inhibitor + mild hypothermia group (IH group). The rat model of cerebral I/R injury was prepared using the filament occlusion method. The filament was removed to restore blood flow after the left middle cerebral artery was blocked for 2 h, and the rats′ brain and rectal temperature were maintained at 36-37 ℃ during the period. The vessels were only isolated and ligated without occlusion in S group. In H group, the entire body was wiped with 75% ethanol immediately after removing the filament, and the brain and rectal temperatures were maintained at 32-33 ℃ for 3 h, and the other procedures were the same as those previously described in I/R group. In IH group, GSTM1 inhibitor itaconic acid 8.6 mg/kg was intraperitoneally injected at 24 and 1 h before developing the model, and the other procedures were the same as those previously described in H group. Neurological deficits were evaluated using a modified neurological severity score (mNSS) at 24 h of reperfusion, and then the animals were sacrificed and the brains were removed for observation of cerebral infarction (by TTC staining) and for determination of the expression of GSTM1, M1-type microglial marker inducible nitric oxide synthase (iNOS), and M2-type microglial marker arginase-1 (Arg-1) (by Western blot), expression of GSTM1, iNOS and Arg-1 mRNA (quantitative real-time polymerase chain reaction) and contents of interleukin-6 (IL-6), IL-10, tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) (by enzyme-linked immunosorbent assay). Results:Compared with S group, the mNSS and percentage of cerebral infarct size were significantly increased, and the expression of iNOS and Arg-1 protein and mRNA was up-regulated, the expression of GSTM1 and mRNA was down-regulated, and the contents of IL-6, TNF-α, IL-10 and TGF-β were increased in the other three groups ( P<0.05). Compared with I/R group and IH group, the mNSS and percentage of cerebral infarct size were significantly decreased, and the expression of iNOS protein and mRNA was down-regulated, the expression of Arg-1 protein and mRNA and GSTM1 was up-regulated, the contents of TNF-α and IL-6 were decreased, and the contents of TGF-β and IL-10 were increased in H group ( P<0.05). Conclusions:Up-regulated expression of GSTM1 is involved in mild hypothermia-induced mitigation of cerebral I/R injury, which is associated with inhibition of microglial polarization toward the M1 phenotype and promotion of polarization toward the M2 phenotype.

Objective:To explore the characteristics of weekly gestational weight gain (GWG) in women with obesity and its correlation with the risk of macrosomia.Methods:Clinical data of women with singleton pregnancy and pre-pregnancy body mass index (PPBMI) ≥28 kg/m 2 were retrospectively analyzed, from January 2014 to December 2019, in Beijing Obstetrics and Gynecology Hospital, Capital Medical University (Beijing Maternal and Child Health Care Hospital). The participants were divided into three groups based on their PPBMI: group A (28-<30 kg/m 2), group B (30-<32 kg/m 2), and group C (≥32 kg/m 2). The study compared the characteristics of GWG among the three groups, explored the correlation between the weekly weight gain during each gestational stage and the risk of macrosomia, and discussed the impacts of the GWG pattern in women with different PPBMI on the risk of macrosomia. Chi-square (or Fisher's exact), Kruskal-Wallis, and Mann-Whitney U tests were performed for statistical analysis. Multivariate logistic regression was used to analyze the impact of weekly weight gain in specific gestational stages on macrosomia. Results:(1) A total of 2 046 participants were included in the study, with 982 in group A, 588 in group B, and 476 in group C. For all of the 2 046 cases, the median PPBMI was 30.1 kg/m 2 (29.0-31.9 kg/m 2), GWG was 10.5 kg (7.3-14.0 kg), and neonatal birth weight was 3 520 g (3 215-3 816 g) with 60 (2.9%) ≥4 500 g, and the biggest baby weighed 5 580 g. Out of the births analyzed, macrosomia occurred in 318 cases (15.5%). (2) Among the three groups (A, B and C), the differences in maternal age [32.0 years (29.0-35.0 years), 32.0 years (29.0-35.0 years) and 32.0 years (29.0-34.0 years), H=6.58] and women with a history of type 2 diabetes mellitus [0.9% (9/982), 0.3% (2/588) and 1.9% (9/476), χ2=6.61] were statistically significant (all P<0.05). (3) The weekly weight gain in each group exhibited a gradual upward trend before 20-24 weeks, reached a plateau at 24-32 weeks, peaked at 32-36 weeks, and subsequently declined. The weekly weight gain of group A in the pre-pregnancy to 14 weeks [0.14 kg/week (0.00-0.25 kg/week)], 14 to 20 weeks [0.25 kg/week (0.17-0.42 kg/week)], and 20 to 24 weeks [0.38 kg/week (0.25-0.63 kg/week)] were higher than those of group B [0.07 kg/week (－0.03-0.21 kg/week), 0.25 kg/week (0.10-0.42 kg/week), and 0.38 kg/week (0.22-0.60 kg/week)], respectively ( Z value was－3.73,－2.16, and－2.01, all P<0.05). Likewise, the weekly weight gain of group B in the above three stages were all higher than those of group C [0.07 kg/week (－0.10-0.21 kg/week), 0.17 kg/week (0.05-0.33 kg/week), and 0.25 kg/week (0.08-0.50 kg/week)], respectively ( Z value was－2.55,－3.28, and－3.25, all P<0.05). (4) The risk of macrosomia increased with the weekly weight gain in specific gestational stages in different PPBMI groups. In group A, the stages correlated with increased risk were 14-20 weeks [adjusted odd ratio ( aOR)=2.669, 95% CI: 1.378-5.169] and 20-24 weeks ( aOR=1.764, 95% CI: 1.143-2.723), while the stages were 20-24 weeks ( aOR=2.149, 95% CI: 1.156-3.996) and 36 weeks until delivery ( aOR=1.888, 95% CI: 1.268-2.810) in group B, and pre-pregnancy to 14 weeks ( aOR=3.515, 95% CI: 1.158-10.665) and 14-20 weeks ( aOR=3.021, 95% CI: 1.058-8.628) in group C (all P<0.05). The risk of macrosomia increased when the weekly weight gain of both risk-related stages in group A ( aOR=2.255, 95% CI: 1.029-4.940) ≥50th percentile, and group B ( aOR=4.399, 95% CI: 1.017-19.023) ≥75th percentile, and for group C ( aOR=3.404, 95% CI: 1.004-11.543) when the weekly weight gain above 25th percentile (all P<0.05). Conclusions:Weekly GWG demonstrates an observable gradual acceleration pattern in women with obesity. Therefore, clinical attention should be directed towards monitoring fluctuations in the weekly weight gain in this population, as excessive weekly weight gain before 24 gestational weeks is associated with an elevated risk of macrosomia.
