Objective:To analyze the relationship between serum GATA binding protein-3(GATA3)and eosinophilic cationic protein(ECP)and lung function indexes in children with obliterated bronchiolitis and their predictive value for poor prognosis.Methods:96 children with bronchiolitis obliterans admitted to our hospital from January 2022 to July 2024 were divided into mild group(34 cases)and moderate to severe group(62 cases)according to their severity.Serum GATA3,ECP levels and lung function indexes were detected in the two groups,and Pearson correlation was used to analyze the correlation between serum GATA3,ECP levels and lung function indexes.According to the levels of serum GATA3 and ECP,they were divided into high GATA3 group and low GATA3 group,high ECP group and low ECP group.The incidence of adverse prognosis in different groups was compared.Area under ROC curve(AUC)was used to evaluate the predictive efficacy of serum GATA3 combined with ECP for poor prognosis.Results:The levels of serum GATA3 and ECP in moderate and severe group were higher than those in mild group(P＜0.05).By Pearson correlation analysis,serum GATA3 and ECP levels were negatively correlated with tidal volume(VT),peak-to-expiratory volume(VPEFNE)and peak-to-time ratio(TPTEF/TE)in children with bronchiolitis obliterans(P＜0.05).The incidence of adverse prognosis in the high GATA3 group was higher than that in the low GATA3 group,and the incidence of adverse prognosis in the high ECP group was higher than that in the low ECP group(P＜0.05).ROC curve analysis showed that serum GATA3 combined with ECP had a sensitivity of 90.45％,specificity of 52.37％and AUC of 0.893 in predicting adverse prognosis of children with bronchiolitis obliterans.Conclusion:Serum GATA3 and ECP are closely related to pulmonary function indexes in children with bronchiolitis obliterans.The combined effect of GATA3 and ECP is better in predicting poor prognosis,and it has a certain suggestive role in evaluating the disease.

OBJECTIVE: Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11). METHODS: To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells. RESULTS: The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed. CONCLUSION The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Extensive studies have identified potential adverse effects on semen quality of obesity, based on body mass index, but the association between body fat distribution, a more relevant indicator for obesity, and semen quality remains less clear. We conducted a longitudinal study of 4304 sperm donors from the Guangdong Provincial Human Sperm Bank (Guangzhou, China) during 2017-2021. A body composition analyzer was used to measure total and local body fat percentage for each participant. Generalized estimating equations were employed to assess the association between body fat percentage and sperm count, motility, and morphology. We estimated that each 10% increase in total body fat percentage (estimated change [95% confidence interval, 95% CI]) was significantly associated with a 0.18 × 10 6 (0.09 × 10 6 -0.27 × 10 6 ) ml and 12.21 × 10 6 (4.52 × 10 6 -19.91 × 10 6 ) reduction in semen volume and total sperm count, respectively. Categorical analyses and exposure-response curves showed that the association of body fat distribution with semen volume and total sperm count was stronger at higher body fat percentages. In addition, the association still held among normal weight and overweight participants. We observed similar associations for upper limb, trunk, and lower limb body fact distributions. In conclusion, we found that a higher body fat distribution was significantly associated with lower semen quality (especially semen volume) even in men with a normal weight. These findings provide useful clues in exploring body fat as a risk factor for semen quality decline and add to evidence for improving semen quality for those who are expected to conceive.
