ObjectiveTo investigate the effects of different fermentation methods and times on the fungal flora and chemical composition of Aurantii Fructus， in order to obtain the optimal fermentation conditions and flora structure， and to ensure the stability and controllability of the fermented varieties. MethodsScanning electron microscopy was used to observe and analyze the colony characteristics on the surface of Aurantii Fructus under different fermentation conditions. Internal transcribed spacer 2（ITS2） high-throughput sequencing， combined with fungal community diversity analysis and fungal community structure analysis， were used to obtain the fungal flora microbial categories of Aurantii Fructus under the conditions of traditional pressure-shelf fermentation and non-pressure-shelf natural fermentation for 7， 14， 21 d（numbered Y1-Y3 for the former， and numbered F1-F3 for the latter）， respectively. At the same time， the chemical components in the fermentation process were detected by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）， combined with principal component analysis（PCA）， partial least squares-discriminant analysis（PLS-DA） and compound retention time， parent ions， characteristic fragment ions and other information， the differential compounds between the different fermentation samples were screened and identified. ResultsThe analysis of fungal community diversity showed that the dominant flora did not change at different fermentation time points in the traditional pressure-shelf fermentation method， while in the non-pressure-shelf natural fermentation method， there was a significant difference with the fermentation process， and at the genus level， the dominant genus of samples Y1， Y2， Y3 and F2 was Aspergillus， while the dominant genera of samples F1 and F3 were both Rhizopus. This indicated that the microbial growth environment provided by the traditional fermentation method was more stable， and the microbial community structure was more stable， which was more conducive to the stable and controllable fermentation process and fermented products. A total of 155 compounds were identified by compositional analysis， including 70 flavonoids， 38 coumarins， 10 alkaloids， 34 organic acids and 3 other compounds. After fermentation， two new components of ribalinine and pranferin were produced. Different fermentation conditions also brought about differences in chemical composition， multivariate statistical analysis obtained 26 differential compounds under two different fermentation methods， mainly including flavonoids， organic acids and coumarins. Comprehensively， the microbial community structure of samples fermented by the traditional pressure-shelf method of Aurantii Fructus for 14 d was stable， the species richness was high and the overall content of differential compounds was high， which was the optimal processing condition. ConclusionCompared with non-pressure-shelf natural fermentation， the traditional method has obvious advantages in terms of the stability of the microbial community structure and the content of chemical compounds， and the optimal condition is 14 days of fermentation. This study is helpful to promote the quality stability and fermentation bioavailability of fermented products of Aurantii Fructus， as well as to provide an experimental basis for the further improvement of the quality control methods of this variety.

Gender, age, educational level, overweight/obesity, hypertension, dyslipidemia, history of impaired glucose regulation and family history of type 2 diabetes mellitus are factors affecting the development of diabetes among high-risk populations.

Objective:To explore the predictive value of serum 25-hydroxyvitamin D [25 (OH) D] and interleukin-6 (IL-6) levels in the development of osteoporosis (OP) in gestational diabetes mellitus (GDM) during early pregnancy.Methods:A total of 178 pregnant women with GDM admitted to Shanxi Provincial Children’s Hospital from Sep. 2018 to May. 2022 were selected as the research subjects and divided into OP group and non-OP group based on bone density. General information of patients was collected, and biochemical indicators related to bone metabolism were measured, including calcium (Ca), β-collagen special sequence ( β-CTX), type 1 procollagen amino-terminal peptide (PINP), n-terminal bone calciuim (N-MID), osteocalcin (OC), and bone alkaline phosphatase (BAP). The levels of 25 (OH) D and IL-6 in the serum of the two groups were measured. The predictive value of 25 (OH) D and IL-6 levels for GDM complicated with OP was analyzed. Results:Compared with the non-OP group (29.95±6.88), the serum 25 (OH) D level was significantly lower in the OP group (20.78±6.02) ( t=5.56, P<0.001), and the IL-6 level was significantly higher in the OP group (75.19±9.15) than in the non-OP group (50.23±10.08) ( t=10.26, P<0.001). There was no significant difference in the levels of Ca, P, β-CTX, PINP, or N-MID between the two groups (all P>0.05). The levels of BAP (13.25±3.12) and OC (6.62±1.24) in the OP group were significantly lower than those in the non-OP group (BAP: 18.23±3.78, t=5.52, P<0.001; OC: 8.75±1.52, t=5.87, P<0.001). Pearson correlation analysis showed a positive correlation between 25 (OH) D level and bone density, BAP, and OC ( r=0.26, 0.21, 0.23, all P<0.05), while IL-6 level showed a negative correlation with bone density, BAP, and OC ( r=-0.39, -0.21, -0.27, all P<0.05). ROC curve analysis showed that serum 25 (OH) D and IL-6 could serve as effective diagnostic markers for GDM complicated with OP (AUC=0.853, P<0.0001; AUC=0.869, P<0.0001) during early pregnancy. Conclusions:The serum 25 (OH) D level is decreased and IL-6 level is increased in GDM patients with OP during early pregnancy. The levels of serum 25 (OH) D and IL-6 have predictive value for the development of GDM complicated with OP during early pregnancy.

Objective: To investigate the attitude and behaviors towards tobacco control among civil servants in smoke-free governments of Ningbo City, so as to provide insights into the construction of smoke-free governments. Methods: Ten governments were randomly sampled from city-level and county/district-level smoke-free governments in Ningbo City using a stratified random sampling method, and 10 civil servants were sampled from each government using a convenient sampling method. Participants' demographics, attitude and behaviors towards tobacco control and second-hand smoke exposure were collected using a self-designed questionnaire and descriptively analyzed. Results: A total of 1 100 civil servants were recruited, including 466 men (42.36%) and had a mean age of (39.02±9.38) years. There were 1 005 participants favoring “civil servants should refuse smoking firstly” (91.36%), 1 058 participants favoring “governments should build a smoke-free environment firstly” (96.18%), 1 075 participants favoring “smoking should be completely banned in any indoor public places” (97.73%), 913 participants thinking that smoking should be completely banned in any indoor public places (83.00%) and 813 participants thinking that tobacco control regulations are implemented satisfactorily in their workplaces (73.91%). The overall prevalence of current smoking was 11.91% among participants, and the prevalence of current smoking was 28.11% among male participants. Among all current smokers, 84 attempted to quit smoking (64.12%), and 89 had willingness or plans to quit smoking (67.94%). The proportion of second-hand smoke exposure in workplaces was 40.97% among non-smokers in the past one week. Conclusions The civil servants in Ningbo City has correct awareness of smoke-free governments, active attitudes towards tobacco control and low prevalence of smoking. However, smoke-free regulations remain to be improved and long-term tobacco control mechanisms remain to be created in governments in Ningbo City

Objective: To investigate the e-cigarette use and its influencing factors among middle school students in Ningbo City, Zhejiang Province, so as to provide insights into e-cigarette control among adolescents. Methods: Students of junior high schools, high schools and vocational high schools in Ningbo City were sampled using a multi-stage stratified cluster random sampling method from September to October 2021. Students' general information, cigarette and e-cigarette use and e-cigarette advertising exposure were collected using 2021 China Youth Tobacco Survey Questionnaire, and proportions of e-cigarette current use and attempt to use were analyzed. Factors affecting the attempt to use e-cigarettes were identified using a multivariable logistic regression model. Results: Totally 1 591 questionnaires were allocated, and 1 574 valid questionnaires were recovered, with an effective rate of 98.93%. The respondents included 863 males (54.83%) and 711 females (45.17%); 787 junior high school students (50.00%), 535 high school students (33.99%) and 252 vocational high school students (16.01%). The proportion of current e-cigarette use was 1.91% and the proportion of attempt to use e-cigarettes was 6.61%. Multivariable logistic regression analysis identified males (OR=2.544, 95%CI: 1.438-4.501), living in rural areas (OR=2.084, 95%CI: 1.195-3.634), having close friends who were smokers (OR=4.828, 95%CI: 2.936-7.940), witnessing teachers smoking at school (OR=2.766, 95%CI: 1.642-4.659), e-cigarette advertising exposure (OR=2.155, 95%CI: 1.315-3.532), current cigarette use (OR=9.365, 95%CI: 2.610-33.603) and attempt to use cigarettes (OR=7.519, 95%CI: 4.115-13.737) as promoting factors for the attempt to use e-cigarette. Conclusions There are e-cigarette use behaviors among middle school students in Ningbo City. Having teachers or close friends who were smokers, cigarette use behaviors and e-cigarette advertising exposure may increase the risk of attempt to use e-cigarettes among middle school students.

Galactinol synthase (GolS) is a key enzyme in the biosynthetic pathway of raffinose family oligosaccharides (RFOs) and plays an important role in plant responses to abiotic stresses. However, the molecular characteristics of the GolS family members in soybean was not well-known. In this study, six members of GmGolS gene family were genome-widely identified, and their physicochemical properties, chromosomal localization, evolutionary relationship, gene structure, conserved motifs, secondary structure, tertiary structure, tissue-specific expression patterns and the expression levels under salt and drought stresses were analyzed. The results showed that six soybean GolS genes were unevenly distributed on four chromosomes, the range of the isoelectric points of six GmGolS proteins was 5.45-6.08, the molecular weight range was 37 567.07-38 817.59 Da, and the number of amino acids was 324-339 aa. The results of subcellular localization showed that 4 proteins were located in the chloroplast, and 2 proteins in the cytoplasm. Phylogenetic tree analysis showed that the members of the soybean GolS gene family were closely adjacent to each other, and were evolutionarily conservative. Six gene members contain 3 or 4 exons. Prediction of secondary and tertiary structures showed that the spatial structure of proteins of all family members was mainly composed of α-helix and random coil structure, with less β-turn and extended chain structure. Tissue-specific expression analysis showed that six GmGolS members expressed to variable degrees in seeds, roots, root hairs, flowers, stems, pods, nodules and leaves. Expression analysis based on qRT-PCR showed that all GmGolS genes showed different degrees of up-regulated expression under salt and drought treatment, indicating that these genes may be related to the response of plants to salt-tolerance and drought-resistance. These results may facilitate subsequent functional analysis of soybean GolS genes.
