ABSTRACT

ObjectiveTaking Achyranthis Bidentatae Radix(ABR) from different origins as samples, to quantitatively analyze the chemical composition and chromaticity of ABR with different processing degrees, and clarify the correlation and change law between color and composition in the processing process of ABR, so as to provide reference for the quality evaluation of processed products of ABR. MethodThe colorimeter is used to measure the chromaticity values of three kinds of processing degrees of ABR in different origins to show the color value change trend during the processing process, and the color parameters of wine-processed and salt-processed products of ABR with different processing degrees were analyzed by principal component analysis(PCA), orthogonal partial least squares-discriminant analysis(OPLS-DA) and other analysis methods. The contents of eight representative components of ABR were measured by high performance liquid chromatography(HPLC), the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis, and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis, and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing, and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural, polypodine B, β-ecdysterone, 25R-inokosterone, 25S-inokosterone, ginsenoside Ro, chikusetsusaponin Ⅳa and polysaccharides as variables, the discriminant function was established respectively, and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function. ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters, and the results could significantly distinguish different processed products. During the process of wine and salt processing, the contents of 5-hydroxymethylfurfural, ginsenoside Ro, and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree, while the contents of polypodine B, β-ecdysterone, 25R-inokosterone, 25S-inokosterone and polysaccharides showed a gradual decreasing trend, indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value(L*) and the total color difference value(E*ab)(P<0.01), and positively correlated with the red-green value(a*) and the yellow-blue value(b*)(P<0.01), and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab(P<0.01). The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis, and their accuracy rates in the training samples were 93.75% and 95.83%, respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution, and the correct rate was 100%. ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent, and the color value can better distinguish ABR with different processing degrees, and the color of ABR is related to some representative components in the processing process, indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.

ABSTRACT

With the development of the understanding of bronchial asthma(asthma for short) and the accumulation of diagnosis and treatment experience, people realize that asthma is a heterogeneous physical and mental disease.Psychosocial stress can increase the frequency of asthma attacks in children and increase the burden of family and society.Psychosocial stress from individual, family and other levels transduces signals in the brain, which are transmitted to downstream effectors, producing effectors such as adrenocorticosteroids, enhancing Th2 and Th17 cell responses, inhibiting Treg cell responses, and influencing specific asthma related genotypes.This paper reviews the mechanism of psychosocial stress on asthma, in order to better control and treat asthma and improve the quality of life of children with asthma.

ABSTRACT

Objective:To explore the protective effects of breastfeeding on behavioral problems at 4 years in children born to mothers with gestational diabetes mellitus (GDM).Methods:Based on the Ma' anshan Birth Cohort (MABC) study, 305 GDM women and their children were recruited in this study from Ma' anshan Maternal and Child Health Care Hospital from May 2013 to September 2014. Total breastfeeding duration was followed up at 42 d, 3, 6, 12, and 18 months postpartum as well as the breastfeeding intensity within 6 months. All the subjects were divided into breastfeeding group ( n=256, including exclusive breastfeeding and mixed feeding) or bottle feeding group ( n=49). Internalizing and externalizing behavioral problems at age 4 were assessed using Achenbach Child Behavior Checklist (CBCL/1.5~5) and their association with breastfeeding were analyzed using robust Poisson regression. Controlling false discovery rate was applied for multiple test correction. Results:Compared with bottle feeding, breastfeeding was a protective factor for depression in children ( RR=0.23, 95% CI: 0.05-0.98, q=0.048) when the duration was 4-5 months; for somatic complaints ( RR=0.36, 95% CI: 0.14-0.95, q=0.047) and anxiety ( RR=0.19, 95% CI: 0.06-0.62, q=0.010) with a breastfeeding duration of 6-11 months; and for depression ( RR=0.46, 95% CI: 0.25-0.83, q=0.039) and anxiety ( RR=0.12, 95% CI: 0.03-0.49, q=0.006) with a breastfeeding duration of 12 months and above. Compared with bottle feeding within 6 months, mixed feeding had a protective effect on somatic complaints ( RR=0.29, 95% CI: 0.13-0.64, q=0.026) and anxiety ( RR=0.18, 95% CI:0.07-0.52, q=0.002). Conclusions:The findings suggested that breastfeeding had a protective effect on behavioral problems at age 4 in children exposed to GDM. Women with GDM should be encouraged to breastfeed.

ABSTRACT

In recent years, the increasing incidence of perinatal depression has become an important public health problem. In addition to the traditional social demographic factors, biological factors, obstetric factors, etc., the association between air pollution and perinatal depression (PND) has also attracted more and more attention. In this paper, studies on the association between air pollution and PND were reviewed, especially the associations of PND with ambient air pollutants such as PM2.5, PM10, NO2, and O3 as well as indoor air pollutants such as tobacco smoke, and the characteristics and possible biological mechanisms of the influence of different pollutants on PND were summarized. Based on the available studies, various outdoor air pollutants are associated with PND, and some pollutants may exhibit a dose-response relationship with it. As for indoor air pollution, studies only have focused on the impact of tobacco exposure on PND, and as yet, no study has explored the association between other indoor pollutants (e.g. cooking oil smoke and solid fuel) and PND. Current studies indicate that air pollution may act on PND through oxidative stress and neuroendocrine mechanisms, but the exact biological mechanism remains to be further studied. In the future, further studies should be encouraged on the epidemiological associations of other indoor air pollutants with PND and the interactions between other factors and air pollution on PND, and the underlying biological mechanisms, to provide new insights for the prevention of PND from the perspective of environmental health.

ABSTRACT

Objective:To deliver understanding of the latest research progress on clinical trials and approval of dermatological drugs in China in 2020.Methods:A registration and information disclosure platform for drug clinical studies and a query system for domestic and imported drugs in the National Medical Products Administration of China were searched for registered clinical trials and approved dermatological drugs, respectively. The number and stages of clinical trials, indications and classification of involved products, and listed dermatological drugs in 2020 were summarized and depicted.Results:There were 157 dermatological drug trials registered in China in 2020, accounting for 6.16% of all the 2 548 clinical drug trials, including 127 (80.9%) initiated by Chinese pharmaceutical enterprises and 25 (15.9%) international multicenter trials. Among the 127 drug trials initiated by Chinese pharmaceutical enterprises, bioequivalence trials were mostly common, accounting for 55.9% (71/127) . Compared with global pharmaceutical enterprises, domestic pharmaceutical companies initiated significantly decreased proportions of international multicenter trials (1.9% [3/157] vs. 14.0% [22/157], P < 0.001) , but significantly increased proportions of phaseⅠclinical trials and bioequivalence trials (24.4% [31/127] vs. 10.0% [3/30], 55.9% [71/127] vs. 0, respectively, both P < 0.001) . Totally, 90 kinds of dermatological drug were involved in all the trials, psoriasis, atopic dermatitis and melanoma were the most common indications, and innovative drugs accounted for 53.3% (48/90) ; the proportion of innovative drugs was significantly lower in domestic pharmaceutical companies than in global pharmaceutical companies (43.2% [32/74] vs. 16/16, P < 0.001) . In addition, 28 dermatological drugs developed by 22 pharmaceutical companies were approved in China in 2020, of which 21 drugs were developed by domestic pharmaceutical companies. Conclusion:Clinical drug trials carried out by domestic pharmaceutical companies mostly focus on generic drugs, and it is still necessary for domestic pharmaceutical companies to further improve the innovation ability.

ABSTRACT

Objective To compare the abdominal fat distribution in patients with primary aldosteronism (PA) and essential hypertension (EH), and to analyze the correlation between abdominal fat area and indexes such as glycolipid metabolism and insulin resistance. Methods Forty-five PA and 55 EH patients were collected from inpatients in the First Affiliated Hospital of Zhengzhou University for suspicious secondary hypertension, from September 2016 to February 2019. All patients accepted quantitative computed tomography to measure the total abdominal fat area ( TFA), visceral fat area ( VFA), and subcutaneous fat area ( SFA) when accepted adrenal CT detection. Visceral obesity was defined as VFA≥130 cm2. The percentage of visceral fat area in total abdominal fat area (V%=VFA/TFA), the ratio of visceral fat area to subcutaneous fat area (V/S=VFA/SFA) and the percentage of visceral obesity were calculated. Results TFA and VFA in EH group were higher than those in PA group matched by age, gender, and body mass index (BMI, all P<0.01), and there were without statistically significant differences in SFA, V%, V/S, and the percentage of visceral obesity between the two groups. In PA group, TFA and VFA were positively correlated with homeostasis model assessment of insulin resistance index ( P<0. 01), TFA was positively correlated with triglycerides ( TG) and low density lipoprotein-cholesterol, while SFA was positively correlated with TG (all P<0.05). Conclusion Compared with EH patients matched by age, gender, and BMI, TFA and VFA in PA patients are lower. Abdominal fat area is associated with insulin resistance and blood lipids in PA patients, while VFA exerts a greater effect on insulin resistance than that of TFA and SFA.
