Objective: To explore the association between maternal lipid levels during pregnancy and the risk of overweight and obesity in offspring at 3 years of age, providing scientific evidences for the prevention and control of childhood obesity. Methods: A total of 2 432 mother-child pairs with maternal lipid tests during pregnancy and offspring s physical growth data at 3 years of age were included from the Borin in Guangzhou Cohort Study up to September 2021. Lipid indicators, including high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol(LDL-C), triglycerides (TG), and total cholesterol (TC), were measured at 13-19 +6 weeks (mid pregnancy) and 32-39 +6 weeks (late pregnancy). Children s body mass index (BMI) Z score were calculated according to the World Health Organization s growth standards for children under 5 years old. The lipid Z score were divided into four quartiles: Q 1, Q 2, Q 3 and Q 4. Linear regression was used to analyze the relationship between maternal lipid levels during pregnancy and offspring’s BMI Z score at 3 years of age. Poisson regression with a robust error variance was employed to evaluate the association between maternal lipid levels during pregnancy and the at risk of overweight and obesity in offspring at 3 years of age, after adjusting for maternal age at conception, education level, parity, pre pregnancy BMI and gestational diabetes mellitus. Results: There was a statistically significnt difference in the detection rate of overweight and obesity risk among children with different mothers s pre pregnancy BMI ( χ 2=22.85, P <0.05). Linear regression analysis showed that TG levels in late pregnancy were positively related to BMI Z score ( β=0.10, 95%CI=0.02-0.18, P <0.05). Poisson regression with a robust error variance indicated that, compared with the Q 1 group of TC, the Q 4 group of TC in mid pregnancy was associated with an increased risk of overweight and obesity in offspring at 3 years of age ( RR=1.59, 95%CI =1.04-2.44); compared with the Q 1 group of TG, the Q 4 group of TG during late pregnancy increased the risk of overweight and obesity in offspring at 3 years of age ( RR=1.79, 95%CI =1.02-3.12) (both P <0.05). Conclusions Maternal serum TC level during mid pregnancy can increase the risk of overweight and obesity in offspring at 3 years of age. Maternal serum TG levels during late pregnancy is positively correlated with BMI and the risk of overweight and obesity in offspring at 3 years of age.

Objective To compare the effectiveness of Defocus Incorporated Multiple Segments (DIMS) and High Aspheric Lenslet (HAL) defocus lenses in controlling myopia. Methods A total of 214 children and adolescents who were fitted with defocus lenses (DIMS or HAL) in our hospital from January to June 2023 were selected, including 100 cases in DIMS group and 114 cases in the HAL group. Changes in parameters such as spherical lens power, cylindrical lens power, spherical equivalent (SE), corneal curvature (K), axial length (AL), binocular accommodative response (BCC), positive/negative relative accommodation (PRA/NRA), distance/near latent phoria (DLP/NLP), and accommodative convergence to accommodation ratio (AC/A) were compared between the two groups before wearing and after wearing the lenses for 6 months, and the effectiveness of myopia control between DIMS and HAL was further compared. Results After wearing the lenses (DIMS or HAL) for 6 months, the average increase in axial length was (0.09±0.14) mm, the average increase in spherical lens power was (-0.11±0.23) D, the average increase in astigmatism was (-0.07±0.16) DC, and the average increase in spherical equivalent was (-0.15±0.24) D, with statistically significant differences observed for all these changes (t=9.24, -7.27, -6.60, -9.03, respectively, P < 0.001). Compared with parameters before wearing the lenses, statistically significant differences were noted after wearing for 6 months in spherical lens power, cylindrical lens power, SE, BCC, PRA, DLP, average K, and AL (P≤0.001), except for NRA (t=-0.12, P>0.05), NLP (t=-0.28, P>0.05), and AC/A (t=0.33, P>0.05). The differences in parameters between the two groups after wearing the lenses for 6 months showed a statistically significant difference only in the AL difference (t=4.38, P≤0.001), with no statistically significant differences observed for other parameter differences (P>0.05). Conclusion Wearing defocus lenses has a positive effect on controlling myopia, delaying axial length elongation, and maintaining binocular visual function balance.

Objective:To establish the ultra-high performance liquid chromatography (UPLC) fingerprint and high performance liquid chromatography (HPLC) content determination method of Curcumae Radix standard decoction; To predict the quality markers of Curcumae Radix standard decoction combined with network pharmacology.Methods:UPLC method was used to establish the fingerprint of Curcumae Radix standard decoction, and the common peaks were determined. Combined with chemical pattern recognition techniques such as similarity analysis and clustering analysis, Curcumae Radix standard decoction from different producing areas was studied, and curcumol was used as an index to determine the content of 24 batches of Curcumae Radix standard decoction. At the same time, network pharmacology was used to predict potential of curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one.Results:A total of 24 batches of Curcumae Radix standard decoction from different habitats were compared and analyzed, and 10 common peaks were calibrated. The similarity of 24 batches of samples ranged from 0.982 to 0.999. Clustering analysis and principal component analysis divided them into three categories. Heat map analysis showed that peak 8 (curcumol) and peak 9 ((1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one) were the main components. The content of curcumol in 24 batches of Curcumae Radix standard decoction was 0.69-1.87 mg/g; curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β- (3-oxobutyl) bicyclo [4.1.0] heptan-3-one may regulate the neuroactive ligand-receptor interaction signaling pathway, calcium signaling, and excitation by regulating neuroactive ligand-receptor interaction signaling pathway, calcium signaling, and excitation. It was preliminarily predicted that curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one were potential quality markers of Curcumae Radix.Conclusion:Curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one are potential quality markers of Curcumae Radix standard decoction, and the established fingerprint can be used for the quality control of Curcumae Radix standard decoction.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.
