Objective :
To investigate the combined effects of triclosan(TCS)and PCB153 on the activity of superoxide dismutase(SOD)and the concentration of malondialdehyde(MDA)in zebrafish liver.
Methods :
Adult zebrafish were exposed to a series of concentrations of TCS,and the mortality in each group was observed and recorded during the acute toxicity test process. The concentrations in subsequent combined exposure experiments were arranged on the basis of the 96 h-LC50. The factorial design was used to determine the concentrations of combined exposure groups between TCS(0,0.125,0.5 μmol/L)and PCB153(0,0.05,0.2 μmol/L). After 5,10 and 14 days of exposure,the zebrafish livers were dissected and frozen in each group. The potential interactions of these two compounds were analyzed according to the results of the SOD and MDA.
Results :
The 96 h-LC50 of TCS exposed to adult zebrafish was 2.64 μmol/L(95%CI:2.37-2.89 μmol/L). After 5 days of exposure,combined exposure to 0.5 μmol/L TCS+0.2 μmol/L PCB153 caused lower liver SOD activities than single exposure groups and the control group(P<0.05). After 10 days of exposure,combined exposure to 0.125 μmol/L TCS+0.05 μmol/L PCB153,0.5 μmol/L TCS+0.05 μmol/L PCB153 caused lower liver SOD activities than single exposure groups and the control group(P<0.05). After 14 days of exposure,combined exposure to 0.5 μmol/L TCS+0.05 μmol/L PCB153,0.5 μmol/L TCS+0.2 μmol/L PCB153 caused higher liver SOD activities than single exposure groups and the control group(P<0.05). There was an interactive effect between TCS and PCB153 on the liver SOD activity in zebrafish(P<0.05). There was no significant effect of MDA content in each group.
Conclusion
Combined exposure to TCS and PCB153 could enhance (inhibit first) the liver SOD activities in zebrafish,and the interaction was synergistic.

Objective To develop zoledronic acid (ZA)-loaded collagen membranes, and to study its effect on osteoclast and osteoblast so as to investigate whether ZA-loaded membranes can inhibit local bone resorption and promote bone formation. Methods ZA-loaded double-layer (Bio-Gide(R)) and singlelayer(BME-10X(R)) collagen membranes were prepared and divided into eight groups according to the concentrations of ZA in the membrane, namely Group BG0, BG1, BG2, BG3 and BM0, BM1, BM2, BM3 (BG refers to Bio-Gide(R), BM refers to BME-10X(R), 0, 1,2, 3 refer to the concentrations of ZA, 0, 1 ×10-4, 1 × 10-3, 1 × 10-2 mol/L respectively). Blank control group was set without using collagen membrane. The effects of ZA-loaded membranes on osteoclast and osteoblast were assessed using in vitro cell culture models. Results In vitro coculture of ZA-loaded membrane with osteoclast for seven days showed that the percentage of bone resorption area in BG1, BG2, BG3, BM1, BM2, BM3 were 18.80%,14.75%, 14.28%, 20.51%, 15.77%, 15.12% respectively, which were lower than that in BG0 (31.53%) and BM0(32.22%, P <0.05), and the higher ZA loading was, the stronger its inhibition to osteoclast was. In vitro coculture of ZA-loaded membrane with osteoblast for four days indicated that alkaline pbosphatase(ALP) activities in BG2 (154.67 U/g), BM2 (154.33 U/g), BG3 (155.33 U/g), BM3 (152.00 U/g) were higher than that in BG0(129.33 U/g) and BM0(127.67 U/g, P < 0.05). What's more, results from seven-day coculture showed that proliferation index in BG2(7.00) was higher than that in BG0(6.90). Conclusions ZA-loaded collagen membrane can not only inhibit osteoclastic bone resorption but also improve proliferation of osteoblast.

Objective:To explore the incidence and influencing factors of wheezing among children and adolescents aged 3-18 years in 11 cities in China from 2022 to 2023.Methods:From October 2022 to August 2023, 11 cities including Xishuangbanna in Yunnan Province, Suqian in Jiangsu Province, Chifeng and Hohhot in Inner Mongolia, Tangshan in Hebei Province, Changzhi in Shanxi Province, Yinchuan in Ningxia Province, Lanzhou and Dingxi in Gansu Province, Linyi in Shandong Province, and Tonghua in Jilin Province were selected as research sites to recruit kindergarten children and primary and secondary school adolescents in local urban areas. A total of 21 959 children and adolescents were included in this study. Demographic information, wheezing data (whether wheezing has occurred in the past and whether wheezing attacks have occurred in the past one year), personal history, family history and other information were collected through questionnaires. The multivariate logistic regression model was used to analyze the influencing factors of wheezing attacks in the past one year.Results:The mean age of 21 959 children and adolescents was (12.09±3.65) years old, and 52.3% (11 480) were boys. The incidence of wheezing history was 3.7% (816 cases), and the incidence of wheezing attacks in the past year was 2.5% (556 cases). The multivariate logistic regression model analysis results showed that compared with older age, girls, full-term natural delivery, no allergic rhinitis, no family history of allergic diseases, no passive smoking, partial diet, natural conception and childbirth, the children aged 3-18 years with young age, male, partial diet, passive smoking, family history of allergic diseases, allergic rhinitis, cesarean section, premature birth, and assisted reproduction had a higher risk of wheezing [ OR (95% CI): 0.86(0.84-0.88), 1.27(1.07-1.51), 2.31(1.95-2.75), 2.09(1.76-2.47), 3.5(2.80-4.37), 4.05(3.39-4.83), 1.20(1.02-1.43), 2.26(1.66-3.09), and 1.67(1.01-2.78)]. Conclusion:From 2022 to 2023, the incidence of wheezing among children aged 3-18 years in China is not significantly higher than before, and childhood wheezing may be related to factors such as children′s age, gender, dietary habits, family and personal history of allergic diseases, passive smoking, and perinatal period.

Clinical phenotype and gene characteristics of a patient diagnosed with Imerslund-Gr?sbeck syndrome (IGS) in Department of Neurology, Children′s Hospital of Soochow University in December 2018 were analyzed retrospectively, and literature review was conducted.The 16 years and 5 months old boy was admitted to the hospital with symptoms of weakness of lower limbs for 2 weeks.He had a history of megaloblastic anemia and isolated proteinuria.Genetic metabolism of hematuria showed methylmalonic academia.Genetic analysis revealed a compound heterozygous AMN gene mutation[c.742C>T(p.Q248 *) and c. 761G>A(p.G254E)]. These two mutations were derived from his parents respectively, which had been reported before.Symptoms of the patient improved after intramuscular administration of hydroxycobalamin and oral betaine.Review of the literature indicated that the clinical manifestations of AMN gene-related IGS were mostly megaloblastic anemia and isolated proteinuria, and the older children might suffer from neurological symptoms such as movement disorders, dementia, delirium or psychosis.The clinical phenotype of this disease was variable, which might easily lead to misdiagnosis.The patient presented with a special phenotype of mild reversible peripheral neuropathy, which expanded the clinical phenotype of pathogenic genes of AMN gene.In addition, peripheral neuropathy caused by vitamin B 12 metabolic disorders is reversible, and it is suggested to measure vitamin B 12, test related genes and treatment with vitamin B 12 in peripheral neuropathy of unknown etiology.

The medicinal value of vanilla planifolia is of great interest.We analyzed the common princi-pal components of VOCs in different parts of vanilla planifolia,and the human serum albumin (HSA),β-lactoglobulin (β-La) andα-lactalbumin (α-La) were used as template proteins to establish a chain a-nalysis approach with the 'solid phase microextraction gas chromatography-mass spectrometry-multispec-troscopy-physical modelling-pharmacokinetics' (S-M-P-P ) .The mechanisms of the transport and phar-macodynamics for the common principal components of vanilla planifolia were analyzed.The results showed that the common primary VOCs in different parts of vanilla planifolia was vanillin (Van),which attenuated the endogenous fluorescence of HSA/β-La/α-La by static bursting,and formed hydrogen bonds and Van der Waals forces with HSA,and noncovalent complexes with β-La/α-La through hydro-phobic forces.Their interaction facilitates the transport of Van in vivo to intestinal and hepatic tissues and its metabolism by CYP1A2 and CYP2C9 enzymes to exert its pharmacological effects.This study provides a comprehensive and in-depth investigation of the transport mechanisms and pharmacological effects of VOCs from vanilla planifolia,which provides an important reference for understanding the medicinal po-tential of plant derived VOCs.

BACKGROUND: Increasing evidence has shown that visit-to-visit variability (VVV) of blood pressure (BP) is associated with an increased risk of cardiovascular disease (CVD). The objective of this study was to evaluate the impact of VVV of systolic blood pressure (SBP) and diastolic blood pressure (DBP) on the risk of CVD among patients with type 2 diabetes mellitus (T2DM) in China. METHODS: We conducted a retrospective cohort study of 10,163 T2DM patients who were not previously diagnosed with CVD from January 2008 to December 2012 in Ningbo, China. The VVV of BP was calculated using five metrics, including standard deviation (SD), coefficient of variation (CV), variation independent of mean, average real variability, and successive variability (SV) of measurements, obtained over a 24-month measurement period. Hazard ratios and 95% confidence intervals (CIs) were estimated by Cox proportional hazards regression models for the associations of variability in BP with risk of CVD. RESULTS: A total of 894 CVD events were observed during a median follow-up of 49.5 months. The hazard ratio in the highest quintile of SD of SBP was 1.24 (95% CI, 1.01 to 1.52) compared with patients in the lowest quintile. The association between higher VVV of DBP and risk of CVD was not consistent across different metrics and sensitivity analyses. CONCLUSION: Higher VVV of SBP was associated with an increased risk of CVD, irrespective of the mean SBP level. Future studies are needed to confirm these findings.
