This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.

OBJECTIVE: Humans are exposed to complex mixtures of environmental chemicals and other factors that can affect their health. Analysis of these mixture exposures presents several key challenges for environmental epidemiology and risk assessment, including high dimensionality, correlated exposure, and subtle individual effects. METHODS: We proposed a novel statistical approach, the generalized functional linear model (GFLM), to analyze the health effects of exposure mixtures. GFLM treats the effect of mixture exposures as a smooth function by reordering exposures based on specific mechanisms and capturing internal correlations to provide a meaningful estimation and interpretation. The robustness and efficiency was evaluated under various scenarios through extensive simulation studies. RESULTS: We applied the GFLM to two datasets from the National Health and Nutrition Examination Survey (NHANES). In the first application, we examined the effects of 37 nutrients on BMI (2011-2016 cycles). The GFLM identified a significant mixture effect, with fiber and fat emerging as the nutrients with the greatest negative and positive effects on BMI, respectively. For the second application, we investigated the association between four pre- and perfluoroalkyl substances (PFAS) and gout risk (2007-2018 cycles). Unlike traditional methods, the GFLM indicated no significant association, demonstrating its robustness to multicollinearity. CONCLUSION GFLM framework is a powerful tool for mixture exposure analysis, offering improved handling of correlated exposures and interpretable results. It demonstrates robust performance across various scenarios and real-world applications, advancing our understanding of complex environmental exposures and their health impacts on environmental epidemiology and toxicology.

Human cytomegalovirus (HCMV) poses a significant risk of neural damage during pregnancy. As the most prevalent intrauterine infectious agent in low- and middle-income countries, HCMV disrupts the development of neural stem cells, leading to fetal malformations and abnormal structural and physiological functions in the fetal brain. This review summarizes the current understanding of how HCMV infection dysregulates the Wnt signaling pathway to induce fetal malformations and discusses current management strategies.

Objective To investigate the differences in clinical characteristics among children on prolonged mechanical ventilation(PMV)due to different primary diseases.Methods A retrospective analysis was performed on the clinical data of 59 pediatric patients requiring PMV from July 2017 to September 2022.According to the primary disease,they were divided into respiratory disease(RD)group,central nervous system(CNS)group,neuromuscular disease(NMD)group,and other disease group.The four groups were compared in terms of general information,treatment,and outcome.Results There were significant differences among the four groups in age,body weight,Pediatric Logistic Organ Dysfunction-2(PELOD-2)score,Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)score,analgesic and sedative treatment,nutrition supply,rehabilitation treatment,tracheotomy,successful ventilator weaning,and outcomes(P＜0.05).Compared with the RD group,the CNS group and the other disease group had a significantly higher age and a significantly higher proportion of children receiving rehabilitation treatment,and the CNS group had a significantly higher proportion of children receiving tracheotomy(P＜0.008).Compared with the other disease group,the CNS group and the NMD group had significantly lower PELOD-2 and PRISM Ⅲ scores,and the CNS group had a significantly higher proportion of children with successful ventilator weaning and a significantly higher proportion of children who were improved and discharged(P＜0.008).Conclusions There are differences in clinical characteristics among children receiving PMV due to different etiologies.Most children in the RD group have a younger age,and children in the CNS group have a relatively good prognosis.

Objective To investigate the clinical value of thyroid globulin antibody(TgAb)and thyroid peroxidase antibody(TPOAb)in the diagnosis and treatment of papillary thyroid microcarcinoma(PTMC).Methods A total of 346 patients with thyroid nodules who underwent surgical treatment in the hospital from August 2012 to October 2021 were selected as the research objects.According to the postoperative pathologi-cal results,the patients were divided into the benign nodule group,PTMC group and non-micro papillary thy-roid carcinoma(PTC)group.The general data of the patients and thyroid function indexes[free triiodothyro-nine(FT3),free tetraiodothyronine(FT4),thyroid stimulating hormone(TSH),TgAb and TPOAb]before and after operation were collected,the tumor recurrence or lymph node metastasis after operation were ob-served,and the relationship between serum TgAb and TPOAb and the risk and prognosis of PTMC was ana-lyzed.Results The positivity rate of TgAb in the PTMC and non-micro PTC groups was significantly higher than that in the benign nodule group(P<0.05).The TPOAb positivity rate was not significantly different among the three groups(P>0.05).Only the TSH level in the PTMC group was higher than that in the non-micro PTC group(P<0.05).Multivariate logistic analysis showed that younger age,higher TSH and positive TgAb were independent risk factors for PTMC and non-micro PTC(P<0.05).However,the risk of PTC didn't increase with increasing TgAb titres.The positivity rate of TgAb in the PTMC and non-micro PTC groups didn't change significantly within one month after operation,but decreased in one year after operation(P<0.05).The TPOAb positivity rate decreased after operation,but the difference was not statistically sig-nificant(P>0.05).In the PTMC group,four cases had tumor recurrence or lymph node metastasis,and the TgAb level increased by 88.4%,49.5%,5.7%and 84.0%respectively when the tumor recurred or metasta-sized.Among them,the TPOAb level increased by 51.6%,30.0%and 2.9%respectively in three cases and decreased by 53.9%in one case.In the PTMC group,there were 11 patients with cervical lymph node enlarge-ment,and there was no statistical difference in TgAb and TPOAb levels when the condition changed(P>0.05).Conclusion TgAb is a risk factor for PTMC,and can be followed up regularly during the diagnosis and treatment of PTMC.The specificity of TPOAb is not as good as that of TgAb,and appropriate follow-up can be chosen during the course of the disease.

Objective To investigate the efficacy of the therapy of soothing liver and strengthening spleen(shortened as Shugan Jianpi therapy)in the treatment of active thyroid-associated ophthalmopathy(TAO)complicated with dry eye,and to provide a reference basis for clinical treatment.Methods A total of 108 patients with active TAO complicated with dry eye of liver depression and qi stagnation type were randomly divided into observation group and control group,54 patients in each group.Both groups were given conventional treatment for intervention of Graves'disease,and additionally the control group was given hormone shock therapy by intravenous injection of Methylprednisolone Sodium Succinate,and the observation group was treated with Chinese medicine prescription for soothing liver and strengthening spleen orally and intravenous injection of Methylprednisolone Sodium Succinate.The treatment period lasted for 12 weeks,and then the patients were followed up till to the 6th month.The changes of clinical activity score(CAS),proptosis,ocular surface disease index(OSDI),corneal fluorescein staining(FL),Schirmer I test(SIT)and tear film break-up time(BUT)in the two groups were observed before and after the treatment.After treatment,the clinical efficacy of the two groups was evaluated.Results(1)After 6 months of treatment,the total effective rate in the observation group was 94.44%(51/54)and that in the control group was 74.07%(40/54),and the intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the CAS,OSDI score and proptosis of the patients in the two groups were all lower than those before treatment(P＜0.01),and the reduction in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the indicators of tear secretion function such as SIT,FL score and BUT of patients in the two groups were improved compared with those before treatment(P＜0.01),and the improvement in the observation group was significantly superior to that in the control group,the differences being all statistically significant(P＜0.01).Conclusion Shugan Jianpi therapy exerts certain clinical efficacy in treating patients with active TAO complicated with dry eye of liver depression and qi stagnation type,which can effectively relieve the proptosis,prolong the tear film break-up time,promote the secretion of tears and the repair of corneal epithelium,improve the visual function,and enhance the quality of life of the patients.
