ABSTRACT
【Objective】 To review the scientific research advances in the field of preschool children′s nutrition from 2012 to 2022, in order to provide reference for relevant policy formulation and further scientific exploration in this area. 【Methods】 High-quality literature published both domestically and internationally between 2012 and 2022 was retrieved through Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) database. Excel and CiteSpace software were applied to visualize the research hotspots and frontier trends. 【Results】 A total of 1 816 English articles and 110 Chinese articles were included in the analysis. The cooperation network density of research institutions and authors was found to be low. Excluding the search terms, the top three English keywords were vitamin A (0.74), intervention (0.67), obesity prevention (0.55); the top three Chinese keywords were "anemia" (0.41), "obesity" (0.38), and "nutritional status" (0.18). In Chinese and English clusters, "anemia" and "physical activity" ranked first, respectively. The latest burst words identified were "dietary pattern" and "diet quality". 【Conclusions】 The number of English literature published in the field of preschool children′s nutrition is increasing, but it has shown a downward trend in the past three years in China. There are few studies in this field in China. The research hotspots primarily focus on the nutritional status of preschool children, with less attention paid to intervention research and methodological exploration. Further research in the field of preschool children′s nutrition in China may need to focus on the external determinants of preschool children′s nutrition, such as parental education, diet and food supply.
ABSTRACT
Background Steel workers are exposed to occupational hazardous factors such as dust, noise, and heat, and often work in shifts, making them prone to sleep disorders. Objective To explore potential influencing factors of sleep disorders among workers in a steel enterprise in Gansu Province, and provide a basis for reducing the risk of sleep disorders among them. Methods From January to March 2022, a self-made questionnaire combined with the Pittsburgh Sleep Quality Index (PSQI) were used to investigate the employees of a steel enterprise in Gansu Province. According to their PSQI scores, they were divided into a normal sleep group and a sleep disorder group. The general demographic variables of the two groups were balanced by 1∶1 propensity score matching (PSM). Multiple logistic regression was used to analyze the contributing factors of sleep disorders. Restricted cubic spline (RCS) model was used to analyze potential dose-response relationship between weekly working hours and sleep disorders. Results The prevalence of sleep disorders in the steel workers was 48.06% (6029/12544). After PSM, 5847 pairs were successfully matched, and the distributions of matched variables were well balanced between the two groups. The results of multiple logistic regression showed that hypertension (OR=1.39, 95%CI: 1.24, 1.56), diabetes mellitus (OR=1.34, 95%CI: 1.07, 1.66), three-shift system (OR=1.26, 95%CI: 1.12, 1.41), dust exposure (OR=1.14, 95%CI: 1.01, 1.29), noise exposure (OR=1.23, 95%CI: 1.09, 1.39), heat exposure (OR=1.16, 95%CI: 1.04, 1.29), and work injury (OR=1.22, 95%CI: 1.02, 1.46) increased the risk of sleep disorders. Compared with workers with < 10 years of service, those with 10-20 years (OR=1.31, 95%CI: 1.19, 1.44), 20-30 years (OR=1.34, 95%CI: 1.19, 1.52), and ≥30 years of service (OR=1.35, 95%CI: 1.19, 1.53) had a higher risk of sleep disorders. Compared with non-exercise workers, the risk of developing sleep disorders was lower in workers with occasional exercise (OR=0.61, 95%CI: 0.56, 0.66) and regular exercise (OR=0.55, 95%CI: 0.49, 0.62). The RCS model showed that the weekly working hours and sleep disorders in the steel workers showed a nonlinear dose-response relationship (P<0.05 for overall trend, P<0.05 for nonlinear test). The relationship between weekly working hours and sleep disorders showed a "U" shaped distribution, with a significant increase in the risk of sleep disorders when the weekly working hours exceeded 49 h. Conclusion The non-occupational influencing factors of sleep disorders of employees in the steel enterprise include hypertension, diabetes, physical exercise, and occupational influencing factors include length of service, weekly working hours, shifts, dust exposure, noise exposure, heat exposure, and work injuries. It is recommended to consider both occupational and non-occupational factors to formulate appropriate sleep disorder prevention and control measures for steel employees to reduce the risk of sleep disorders.
ABSTRACT
Cough variant asthma(CVA)is a common respiratory disease in clinical practice.The only or main clinical manifestation of CVA is cough.It has similar pathological pathogenesis with asthma,but its pathological changes are sligher than asthma.The research of CVA drugs needs appropriate CVA animal models as the research basis.Based on the characteristics of CVA clinical diseases and syndromes of traditional Chinese and western medicine,combined with the clinical diagnostic criteria of traditional Chinese and western medicine,the CVA animal models are combed and analyzed,in order to provide references for the establishment,evaluation and application of CVA animal models.Chemical induction was used to prepare the commonly used animal models of cough variant asthma,including mice,rats and guinea pigs.The selection of sensitizing agent,adjuvant,activator and cough inducing agent was basically the same in the animal models of cough variant asthma,but there were significant differences in the selection of sensitizing method,sensitizing and stimulating dose,modeling cycle and detection index.Western medicine has clear diagnostic criteria for cough variant asthma,while traditional Chinese medicine can classify cough-variant asthma into different types according to different syndromes.At present,the commonly used animal models of cough variant asthma are highly consistent with the diagnostic criteria of western medicine,but not well consistent with the diagnostic criteria of traditional Chinese medicine,which is insufficient to reflect the symptoms of traditional Chinese medicine.The establishment of CVA animal model combining disease and syndrome,including medical syndromes into the model evaluation criteria,meets the requirements of TCM research on CVA animal model.In model evaluation,behavioral manifestations,HE staining of lung tissue,cell counts in BALF and lung function indicators should be considered in various aspects,and airway excitation test,alveolar lavage fluid eosinophil count,behavioral and other aspects should be distinguished from asthma.
ABSTRACT
Objective:To evaluate the role of Sirtuin 1/nuclear factor κB (SIRT1/NF-κB) signaling pathway in mild hypothermia-induced promotion of microglial polarization during oxygen-glucose deprivation and restoration (OGD/R).Methods:The well-grown BV2 microglia were divided into 4 groups ( n=36 each) using the random number table method: control group (group C), OGD/R group (group O), mild hypothermia group (group M), and mild hypothermia+ SIRT1 specific inhibitor EX527 group (group ME). Cells in group C were commonly cultured without any treatment. Cells in group O were subjected to 3 h of OGD followed by 21 h of restoration of O 2-glucose supply at 37 ℃. Cells in group M were subjected to 3 h of OGD followed by 21 h of restoration of O 2-glucose supply at 33 ℃. Cells in group ME were co-cultured with inhibitor EX527 (final concentration 5 nmol/L) for 12 h in the medium before OGD/R, and the other procedures were conducted as previously described in group M. The cell survival rate was detected by CCK-8 assay. The levels of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and interleukin-10 (IL-10) in supernatant were detected by enzyme-linked immunosorbent assay. The expression of CD206, CD32, inducible nitric oxide synthase (iNOS) and arginine synthase 1 (Arg-1) mRNA was detected by quantitative real-time polymerase chain reaction. The expression of CD206 and CD32 was detected by immunofluorescent staining. The expression of iNOS, Arg-1, SIRT1, NF-κB p65 (p65) and acetylated NF-κB (Ac-p65) was detected by Western blot. Results:Compared with group C, the cell survival rate was significantly decreased, the concentrations of TNF-α, IL-6 and IL-10 in the supernatant were increased, the expression of CD206, Arg-1, CD32 and iNOS was up-regulated, the expression of SIRT1 was down-regulated, and the Ac-p65/p65 ratio was increased in group O ( P<0.05). Compared with group O, the cell survival rate was significantly increased, the concentrations of TNF-α and IL-6 in the supernatant were decreased, the concentration of IL-10 was increased, the expression of CD206, Arg-1 and SIRT1 was up-regulated, the expression of CD32 and iNOS was down-regulated, and the Ac-p65/p65 ratio was decreased in group M ( P<0.05). Compared with group M, the cell survival rate was significantly decreased, the concentrations of TNF-α and IL-6 in the supernatant were increased, the concentration of IL-10 was decreased, the expression of CD206, Arg-1 and SIRT1 was down-regulated, the expression of CD32 and iNOS was up-regulated, and the Ac-p65/p65 ratio was increased in group ME ( P<0.05). Conclusions:SIRT1/NF-κB signaling pathway is involved in mild hypothermia-induced promotion of microglial polarization during OGD/R.
ABSTRACT
Objective:To investigate the effects of mild hypothermia on microglia polarization and janus kinase 2/signal transduction and transcriptional activation factor 3 (JAK2/STAT3) signaling pathway during cerebral ischemia-reperfusion (I/R) in rats.Methods:Forty-five clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 260-280 g, were divided into 3 groups ( n=15 each) by the random number table method: sham operation group (S group), cerebral I/R group (I/R) and mild hypothermia group (H group). In I/R group and H group, cerebral I/R was induced by middle cerebral artery occlusion using a nylon thread in anesthetized animals, the nylon thread was removed to restore the perfusion after 2 h of occlusion, and the rectal temperature was maintained at 36-37 ℃ during the period. Group H was wiped with 75% alcohol for 3 h starting from the time point immediately after reperfusion, and the rectal temperature was maintained at 32-33℃. Modified neurological severity score (mNSS) was evaluated at 24 h of reperfusion. Animals were then sacrificed for determination of the cerebral infarct size (using TTC staining), expression of M1 marker inducible nitric oxide synthase (iNOS), M2 marker arginase 1(Arg-1), phosphorylated JAK2(p-JAK2)and phosphorylated STAT3(p-STAT3)(by Western blot), expression of iNOS mRNA and Arg-1 mRNA (by quantitative polymerase chain reaction), and contents of interleukin-6 (IL-6) and IL-10 (by enzyme-linked immunosorbent assay). Results:Compared with group S, mNSS and cerebral infarct size were significantly increased, the expression of iNOS, Arg-1 protein and mRNA in cerebral ischemic penumbral zone was up-regulated, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio, and contents of IL-6 and IL-10 were increased in the other two groups ( P<0.05). Compared with I/R group, mNSS and cerebral infarct size were significantly decreased, the expression of iNOS protein and mRNA in cerebral ischemic penumbral zone was down-regulated, the expression of Arg-1 and mRNA was up-regulated, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and IL-6 content were decreased, and the IL-10 content was increased in group H ( P<0.05). Conclusions:Mild hypothermia can promote the polarization shift of microglia from M1 to M2 phenotype during cerebral I/R and inhibit the central inflammatory responses, and the mechanism may be related to inhibition of JAK2/STAT3 signaling pathway in rats.
ABSTRACT
Rosacea is a chronic inflammatory disease. In addition to subjective evaluation, some objective quantifiable indices are needed for the diagnosis and treatment of rosacea. Some skin imaging and noninvasive measurement tools have been applied to clinical practice, and can provide quantitative or semi-quantitative indices to assist the diagnosis and treatment of rosacea. This review summarizes relevant research progress to provide evidence for clinical standardized application.
ABSTRACT

A large number of studies have confirmed that rosacea is related to a variety of systemic diseases, including neuropsychiatric diseases such as anxiety, depression, migraine, Alzheimer′s disease and Parkinson′s disease. This review summarizes research progress in the correlation between rosacea and neuropsychiatric diseases, as well as the underlying mechanisms.
ABSTRACT
{L-End}Objective To analyze the correlation between occupational burnout and sleep quality among steelworkers. {L-End}Methods A total of 11 491 steelworkers from a large steel enterprise in Gansu Province were selected as the research subjects using convenient sampling method. The Burnout Questionnaire and the Pittsburgh Sleep Quality Index Scale were used to investigate their occupational burnout and sleep quality. Hierarchical regression analysis was used to analyze the effects of occupational burnout on the sleep quality. {L-End}Results The detection rate of occupational burnout and sleep disorder were 50.4% and 39.0%, respectively. There was a positive correlation between the level of occupational burnout and the total score of sleep quality (Spearman correlation coefficient=0.454, P<0.05). The results of hierarchical regression analysis, adjusting for confounding factors such as gender, age, marital status, education level, alcohol consumption, exercise, weekly working hours, seniority, work shift, noise exposure, dust exposure, and high-temperature work, showed that the score of occupational burnout was positively related to the score of sleep quality(P<0.01), explaining 16.0% of the variance in the score of sleep quality among these steelworkers. {L-End}Conclusion The detection rate of occupational burnout and sleep disorders are relatively high among the steelworkers in this enterprise. Higher levels of occupational burnout are associated with poorer sleep quality. Alleviating occupational burnout among steelworkers may contribute to improving their sleep quality.
ABSTRACT
Photobiomodulation, also known as photochemical modulation, refers to the use of low-power light from various sources to induce photophysical and photochemical modulation without thermal injury in the body. Photobiomodulation is related to the wavelength and energy of light. Target chromophores for light of different wavelengths include cytochrome C oxidase, opsin, porphyrin, etc., and the parameters such as power density, spot size, and energy density determine the energy of light. At present, many in vivo and in vitro studies have confirmed the application potential of photobiomodulation in the treatment of various skin diseases.
ABSTRACT
Localized neurovascular dysregulation is an important factor for the occurrence of rosacea, and it has been confirmed that neurogenic inflammation is a key step in neurovascular dysregulation. Intradermal injection of botulinum toxin can relieve facial flushing and burning sensations, which may be attributed to the inhibition of neuropeptide release from nerve endings and degranulation of mast cells. This review summarizes the research progress in neurogenic inflammation in the pathogenesis of rosacea and botulinum toxin in the treatment of rosacea, aiming to provide a basis for nerve-related basic research and clinical treatment of rosacea.
ABSTRACT
Objective The objective of this study was to explore the differences of serum metabolomics between small cell lung cancer(SCLC)patients and healthy volunteers,and to discover serum potential biomarkers for identification and small cell lung cancer staging. Methods Ultra-performance liquid chromatography time of flight mass spectrometry(UPLS-TOF/MS)was used to establish the serum metabolic profile of SCLC. Principal Component Analysis(PCA)and orthogonal hidden variables were analyzed by the EZinfo2. 0 software. Orthogonal Partial Least Squares Discriminant Analysis(OPLS-DA)was used to analyze the metabolic differ-ences between the case and normal control groups. Through cluster analysis using HMDB and METLIN database to search for the exact mass-to-charge ratio of the difference,preliminary identification of some substances with significant differences was carried out. Results Ten differential metabolites such as lysophosphatidylcholine between patients and control groups were screened and identi-fied by mass spectrometry and database search. There were 10 different metabolites such as glycocholic acid in the contour analysis of SCLC patients with different stages. Conclusion There is a significant difference in serum metabolism between SCLC patients and healthy controls. The discovery of differential metabolites provides experimental evidence for the identification of small cell lung cancer and potential markers of staging.
ABSTRACT
Objective The aim was to screen the expression profiles of microRNAs (miRNAs) in gastrointestinal stromal tumors (GIST) and explore the function of microRNA-301 a (miR-301 a). Methods Collected the tumor and adjacent normal tissues of 45 patients, who were diagnosed primary GIST. The expression profiles of tumor miRNAs in 5 of the 45 patients were obtained by microarray technology, and the abnormal expression levels of miRNAs in the remaining 40 patients were detected by Real Time-PCR as a validation experiment. Correlation analysis was analyzed between the significantly up-regulated expression of miR-301 a and the clinicopathological features of the patients. The MTT experiment was used to explore the effect of miR-301 a on the growth of GIST cell lines. Results Five kinds of miRNAs with high expression and five kinds of miRNAs with low expression were screened out from GIST, of which the expression of miR-301 a was up-regulated most obviously. The expression of miR-301 a was closely related to tumor risk grade, tumor size, mitosis and necrosis (P < 0.05). The overexpression of miR-301 a in GIST cell lines could significantly enhance the proliferation of cells. Conclusions MiR-301 a was up-regulated in GIST, which was closely related to malignant clinicopathological features and could affect the growth and proliferation of tumor cells in vitro. MiR-301 a might be a potential target for future treatment of GIST.
