Objective Using infrared spectroscopy to analyze three kinds of lignum Chinese medicine to provide a theoretical basis for the establishment of medicinal overall quality evaluation system. Methods Functional groups identification, Fourier Transform-infrared spectroscopy(FT-IR) and the second derivative infrared spectroscopy (SD-IR) could be applicable to analyze and identify the overall chemical composition of three kinds of lignum Chinese medicine. Results The main chemical components of Aquilariae Lignum Resinatum (ALR), Dalbergiae Odoriferae Lignum (DOL) and Sappan Lignum (SL) were cellulose, lignin and aromatics. The main chemical compositions of Sappan Lignum (SL) were cellulose, lignin and aromatics. The differences in FT-IR and SD-IR of DOL and SL indicated that they had different aromatic compounds. Conclusion Infrared spectroscopy can be used as a simple and accurate quality control method of three kinds of lignum Chinese medicine.

Objective To provide effective reference for quality analysis of the chemical composition and extraction of astragalus separation process by comparing the extract of astragalus and it’s IR spectra. Methods The saponins and flavonoids in astragalus were firstly extracted by the method of circumfluence with ethanol as solvent and the residue of ethanol-extraction was then used to extract polysaccharides by distilled water. Fourier transform infrared spectroscopy (IR) combined with second derivative infrared spectroscopy was applied to quickly identify astragalus herbs powder, water extraction of astragalus, astragalus alcohol extraction and water extraction of the residue of ethanol-extraction. Results The powder and 70% ethanol extract, 80% ethanol extract were around at 1 735 cm-1 (carbonyl stretching vibration absorption peak) has a weak, broad absorption, while the absorption peak was less obvious in boiling water extraction. So the maln components of astragalus water extraction are polysaccharides and also contaln a small amount of water-insoluble flavonoids. Alcohol extraction malnly contalns saponins and flavonoids, and flavonoid extract volume increases with increasing alcohol concentration in a certaln range.Conclusion This method can be a quick and easy identification for astragalus and it’s extraction for its chemical composition class, and provide the basis for further research quality.

Objective: To explore the relationship of family function with sleep and externalizing problem behaviors of preschool children, so as to provide a guidance for externalizing problem prevention and intervention among preschool children. Methods: From October 2023 to January 2024, a convenience sampling method was used to select 5 138 preschool children from kindergartens in 8 districts of Wuhan City, Hubei Province. Parents completed the survey for Family Adaptability and Cohesion Scale, children s sleep habits and Child Behavior Checklist (CBCL). Spearman correlation analysis was used to examine the correlation of family function with scores of sleep quality and externalizing problem behaviors among preschool children. A mediation model analysis and bootstrap test were conducted to further investigate the mediating role of sleep quality between family function and externalizing problem behaviors. Mplus 8.7 software was used for latent profile analysis of family function. Results: The reported rates of poor sleep quality and externalizing problem behaviors among preschool children were 11.8% ( n =607), 20.0% ( n =1 026). The relevant analysis results showed that family function was negatively correlated with sleep quality and externalizing problem behaviors ( r = -0.20, -0.23), and sleep quality was positively correlated with externalizing problem behaviors ( r =0.27) ( P <0.01). The mediation effect test showed that family function negatively predicted externalizing problem behaviors ( β =-0.079) and sleep quality ( β = -0.075), while sleep quality positively predicted externalizing problem behaviors ( β =0.215) ( P <0.01). The latent profile analysis results showed that family function could be classified into 4 categories: high family function group (23.01%), upper middle family function group (44.65%), moderate family function group (26.24%) and low family function group (6.11%). Compared to high family function, the other three categories significantly positively predicted externalizing problem behaviors, and the mediating effects of sleep quality on different categories of family function were statistically significant [upper middle family function: mediation effect value was 0.022 (95% CI =0.004-0.041) and direct effect value was 0.329 (95% CI =0.263-0.396); middle family function: mediation effect value was 0.087 (95% CI =0.063-0.115) and direct effect value was 0.491 (95% CI =0.416-0.565); low family function: mediation effect value was 0.144 (95% CI =0.107-0.185) and direct effect 0.621 (95% CI =0.503-0.740)] ( P < 0.05 ). Conclusion Family function negatively predicts the externalizing problem behaviors of preschool children, and sleep quality plays a partial mediating role.

Objective:To investigate the clinicopathological characteristics and the risk factors of lymph node metastasis(LNM) of undifferentiated early gastric cancers(EGCs) in elderly patients.Methods:The elderly patients(≥65 years old) who underwent radical gastrectomy with lymph node dissection and were diagnosed as having EGCs in Peking Union Medical College Hospital from January 2010 to August 2019 were included. The clinicopathological characteristics of undifferentiated EGCs(namely signet ring cell EGCs and poorly differentiated EGCs) were compared with those of differentiated EGCs, and the risk factors for LNM of undifferentiated EGCs in the elderly patients were analyzed with logistic regression.Results:Data of 165 elderly EGCs patients were reviewed, including 82 undifferentiated EGCs (11 signet ring cell and 71 poorly differentiated) and 83 differentiated EGCs. The overall LNM incidence was 9.1% (15/165) in elderly EGCs patients, 4.8% (4/83) and 13.4% (11/82) in differentiated and undifferentiated EGCs, respectively. Of all undifferentiated EGCs, the LNM incidence in poorly differentiated EGCs was 15.5%(11/71), and none of 11 signet ring cell EGCs had LNM. Depth of tumor invasion( P=0.019), tumor size( P=0.006), combination of ulceration( P=0.006), depressed gross type( P=0.003) were found to be associated with LNM in elderly undifferentiated EGCs patients under univariate analysis. Multivariate analysis revealed that submucosal invasion( OR=11.98, 95% CI: 1.17-122.84, P=0.037) and tumor size >2 cm ( OR=11.95, 95% CI: 1.88-76.07, P=0.009) were independent risk factors for LNM in elderly undifferentiated EGCs patients. All elderly undifferentiated EGCs patients who met the criteria for expanded indications had no LNM. Conclusion:Submucosal invasion and tumor size >2 cm are independent risk factors for LNM in elderly undifferentiated EGCs patients. The elderly EGCs patients who met the criteria for expanded indications are suitable for endoscopic submucosal dissection.
