Interrelationships among growth hormone, thyroid function, and endocrine-disrupting chemicals on the susceptibility to attention-deficit/hyperactivity disorder.

Abnormal growth hormones and thyroid function may be linked to pathophysiology of attention-deficit/hyperactivity disorder (ADHD). Phthalates and bisphenol-A (BPA), two endocrine-disrupting chemicals (EDCs), may affect the human endocrine system. In this study, we aimed to perform a comprehensive investigation of whether growth hormone, thyroid function, and EDCs exhibited differential levels between ADHD patients and healthy controls. In total, 144 children with ADHD and 70 healthy control subjects were enrolled. Their endocrine systems were evaluated using the serum levels of insulin-like growth factor-1 (IGF-1), IGF-binding protein-3 (IGFBP-3), thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and Free T4. The urinary levels of EDCs, including monoethyl phthalate (MEP), mono-methyl phthalate (MMP), monoethylhexyl phthalate (MEHP), mono-n-butyl phthalate (MnBP), monobenzyl phthalate (MBzP), and BPA, were also examined. Patients with ADHD had lower IGF-1 levels than healthy controls (p = 0.003), but we observed no significant difference in IGFBP-3, TSH, T3, T4, or Free T4. Compared to the control group, patients with ADHD demonstrated higher MEHP levels (p = 0.043), MnBP (p = 0.033), and MBzP (p = 0.040). Furthermore, MEHP levels (p < 0.001) and BPA levels (p = 0.041) were negatively correlated with IGF-1 levels, while IGF-1 levels were negatively correlated with principal components consisting of ADHD clinical symptoms and neuropsychological performance variables. We suggest that MEHP exposure may be associated with decreased serum levels of IGF-1 and increased risk of ADHD. The mechanism underlying this association may be important for protecting children from environmental chemicals that adversely affect neurodevelopment.

[CiteSpace knowledge map of research hotspots and frontiers of traditional Chinese medicine intervention in psoriasis in recent ten years].

This study aimed to investigate the development status of traditional Chinese medicine(TCM) intervention in psoriasis in recent ten years, analyze the research hotspots, and summarize the development trends to provide reference materials for scholars in this field. Taking the available literature related to the field of TCM intervention in psoriasis as the research object, the trends, contents, and source publications were statistically analyzed based on bibliometrics. The research cooperation and co-occurrence of keywords in this field were studied by the knowledge map analysis method based on CiteSpace. The total number of Chinese papers was 2 993 and English papers 285. In terms of publication trend, the annual publication of English papers was low but showed an obvious upward trend, while the increase in Chinese papers fluctuated and tended to be flat. In terms of the content of Chinese papers published, TCM ranked first according to the discipline(2 415). In English papers, the number of publications in pharmacology and pharmaceutical science was the highest(87). Literature source analysis showed that the Chinese and English journals with the most publications were China Journal of Traditional Chinese Medicine and Pharmacy and Evidence Based Complementary and Alternative Medicine, respectively. Beijing University of Chinese Medicine published the most dissertations in China(99). The authors with the most publications in Chinese and English were LI Bin(Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine) and LU Chuan-jian(Guangdong Hospital of Traditional Chinese Medicine). As revealed by the CiteSpace analysis of the research cooperation network, there were four mature and stable core teams in this field, but the cooperation intensity between different teams was weak. According to the keywords co-occurrence knowledge graph constructed by CiteSpace, the current hot keywords in this field are as follows: psoriasis, blood-heat syndrome, blood-stasis syndrome, fire needle, blood-dryness type, imiquimod, TCM bath, etiology and pathogenesis, cytokines, cupping therapy, etc. In summary, Chinese scholars have conducted active exploration and research in the field of TCM intervention in psoriasis in recent ten years. The overall development trend is good, and the breadth and depth of the research are constantly extending. It is suggested that relevant research should be free from discipline restrictions and strive for interdisciplinary integration.

Maternal Supplementation of Probiotics, Prebiotics or Postbiotics to Prevent Offspring Metabolic Syndrome: The Gap between Preclinical Results and Clinical Translation.

Metabolic syndrome (MetS) is an extremely prevalent complex trait and it can originate in early life. This concept is now being termed the developmental origins of health and disease (DOHaD). Increasing evidence supports that disturbance of gut microbiota influences various risk factors of MetS. The DOHaD theory provides an innovative strategy to prevent MetS through early intervention (i.e., reprogramming). In this review, we summarize the existing literature that supports how environmental cues induced MetS of developmental origins and the interplay between gut microbiota and other fundamental underlying mechanisms. We also present an overview of experimental animal models addressing implementation of gut microbiota-targeted reprogramming interventions to avert the programming of MetS. Even with growing evidence from animal studies supporting the uses of gut microbiota-targeted therapies start before birth to protect against MetS of developmental origins, their effects on pregnant women are still unknown and these results require further clinical translation.

Individuals at ultra-high risk of psychosis and first-degree relatives of patients with schizophreniaexperience impaired family functionality and social support deficit in comparison to healthy controls.

AIM: The present study was designed to assess the role of family function and social support in the context of different phases of schizophrenia. METHODS: First-episode patients with experiences of schizophrenia (FEP), ultra-high risk for psychosis (UHR), first-degree relatives (FDR) of patients with experiences of schizophrenia, and healthy controls (HC) (40 per group) were subjected to in-person clinical interviews. The results of these interviews were then used to gauge social support and family function using the Perceived Social Support Scale (PSSS) and the Family Adaptability and Cohesion Scales (FACESII-CV). Data were analyzed through ANCOVA, correlation analysis and logistic regression analyses. RESULTS: We found that family function and social support showed a approximately gradual downward trend through the HC, FDR, UHR, and FEP groups but no significant differences were found in the family function of the FDR, UHR and FDR group. Logistic regression analyses indicated that UHR group patients exhibited decreased family support and family cohesion relative to members of the HC group, but had greater perceived social support than did members of the FEP group. Results for members of the FDR group were in line with those of members of the UHR group. CONCLUSIONS: These findings suggested that both UHR and FDR individuals experience impaired family functionality and social support which expanded the understanding of the psychological characteristics of the prodromal period of schizophrenia. Further explorations are warranted to develop optimal psychosocial interventions.

Montelukast does not increase the risk of attention-deficit/hyperactivity disorder in pediatric asthma patients: A nationwide population-based matched cohort study.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) has been linked to pediatric asthma patients treated with montelukast. This study is the first to use a nationwide health insurance research database (NHIRD) to study whether asthmatic children using montelukast are at an increased risk of ADHD. METHODS: We used data from the Taiwan NHIRD, which is a longitudinal database of one million randomly selected subjects. The enrolled patients were followed up until 2013. Patients younger than and equal to 12 years old with new-onset asthma (ICD-9 CM code 493.X) diagnosed between 1997 and 2013 were enrolled. A multivariate Cox regression analysis was conducted to evaluate the association between montelukast treatment and the risk of ADHD (ICD-9-CM code 314.X). RESULTS: We enrolled a total of 54,487 asthmatic children younger than and equal to 12 years old who had at least one claim of inpatient admission or at least three claims of an ambulatory visit. Montelukast users and match controls were identified by matching age, gender, residence, the comorbidities including allergic rhinitis and atopic dermatitis, admission or emergency department visits due to asthma attack, and index date of starting montelukast in a 1:1 ratio, with 12,806 in the montelukast group and 12,806 in the non-montelukast group. The montelukast group had a similar risk of ADHD (n = 632, 4.94%) as the non-montelukast group (n = 610, 4.76%) [adjusted hazard ratio 1.04; 95% confidence interval, 0.93 to 1.17]. In children treated with montelukast, high cumulative days of montelukast use did not increase the risk of ADHD. CONCLUSION: This nationwide population-based cohort study reveals that asthma children treated with montelukast were not at an increased risk of developing ADHD. Nevertheless, validation of our retrospective survey requires further prospective study.

Frequency and correlates of violence against patients with schizophrenia living in rural China.

BACKGROUND: Violence against patients with schizophrenia is very common, however it is rarely studied in China, especially in primary health care institutions of rural areas. Therefore, we investigated the frequency of violence against patients with community-living schizophrenia in rural China and examined its associated factors and impact on quality of life (QoL) and social function. METHOD: A survey was conducted among 487 patients with schizophrenia living in rural communities. Data about violent victimization experiences in the past 6 months, demographic information, and clinical characteristics were collected by questionnaires. RESULTS: We found that 92 (18.9%) of 487 subjects experienced at least one type of violent event in the past 6 months. Logistic regression analysis suggested that a history of conducting dangerous behaviors(OR = 1.702, P = 0.02, 95%CI: 1.05-2.73), higher Brief Psychiatric Rating Scale (anxiety domain) score (OR = 1.15, P = 0.02, 95%CI: 1.01-1.304) and lower hospitalization rates (OR = 0.89, P = 0.04, 95%CI: 0.81-0.99) were significantly associated with violent victimization in patients with schizophrenia. Analysis of covariance showed the victims of violence tended to have worse social function in patients with schizophrenia living in rural communities of China (P = 0.04). CONCLUSIONS: Individuals with schizophrenia living in rural China had a high risk of being exposed to violence and violent victimization of patients with schizophrenia had adverse consequences for social function. More attention is needed for those patients experiencing violent events, because they are simultaneously possible to conduct dangerous behaviors.

Sexual dysfunction in Chinese rural patients with schizophrenia.

BACKGROUND: Sexual dysfunction is common in patients with schizophrenia, however it is poorly studied in China, especially in primary health care institutions in rural areas. We investigated the prevalence of sexual dysfunction and its correlates including quality of life (QoL), in schizophrenia patients treated in primary care in a rural area in China. METHOD: By using a random numbers table, 21 small town primary care service centers (from 63 totally) were selected in the study. Data of 720 community-dwelling patients with schizophrenia in rural area with diagnoses according to DSM -IV or ICD-10 were collected by interviews. Data on socio-demographic and clinical characteristics including sexual dysfunction and quality of life (QoL) were collected using a standardized protocol and data collection procedure. Data were analyzed using chi-square tests, t-tests, U-tests, ANCOVA and multiple logistic regression as appropriate by SPSS 21.0.The level of significance was set at 0.05 (two-tailed). RESULTS: In this sample, sexual dysfunction was found in 71.3% of the whole sample, 82.7% of female patients and 64.5% of male patients. Multiple logistic regression analysis showed that older age (OR = 1.06, P<0.001, 95%CI: 1.04-1.09) and higher Brief Psychotic Rating Scale (negative domain) score (OR = 1.16, P = 0.01, 95%CI: 1.02-1.31) were significantly associated with sexual dysfunction. Contrary to previous findings, sexual dysfunction was not associated with quality of life after controlling for confounding variables. CONCLUSIONS: More than 2/3 of schizophrenia patients living in a rural area complained of sexual dysfunction, which was associated with older age and more negative psychotic symptoms. Primary care physicians should pay attention to sexual dysfunction during the assessment and treatment of patients with schizophrenia in rural areas in China.

Spectrum of PHEX Mutations and FGF23 Profiles in a Taiwanese Cohort With X-Linked Hypophosphatemia Including 102 Patients.

BACKGROUND/AIM: X-linked hypophosphatemia (XLH), the most common form of hereditary rickets, results from loss-of-function mutations in the phosphate-regulating PHEX gene. Elevated fibroblast growth factor 23 (FGF23) contributes to hypophosphatemia in XLH. This study aimed to characterize PHEX variants and serum FGF23 profiles in Taiwanese patients with XLH. PATIENTS AND METHODS: We retrospectively reviewed the records of 102 patients clinically suspected of having hypophosphatemic rickets from 2006 to 2022. Serum intact Fibroblast growth factor-23 (iFGF23) levels were measured on clinic visit days. PHEX mutations were identified using Sanger sequencing, and negative cases were analyzed using whole-exome sequencing. RESULTS: The majority (92.1%) of patients exhibited elevated FGF23 compared with normal individuals. Among 102 patients, 44 distinct PHEX mutations were identified. Several mutations recurred in multiple unrelated Taiwanese families. We discovered a high frequency of novel PHEX mutations and identified variants associated with extreme FGF23 elevation and tumorigenesis. CONCLUSION: Our findings revealed the PHEX genotypic variants and FGF23 levels in Taiwanese patients with XLH. These results are crucial given the recent approval of burosumab, a monoclonal FGF23 antibody, for XLH therapy. This study provides key insights into the clinical management of XLH in Taiwan.

Evaluation of Infective Endocarditis in Children: A 19-Year Retrospective Study in Taiwan.

BACKGROUND: Infective endocarditis (IE) is an important cause of morbidity and mortality in pediatric patients with heart disease. Little literature has explored differences in the presentation of endocarditis in children with and without heart disease. This study aimed to compare the clinical outcomes and determine the risk of in-hospital death in the study population. METHODS: Data were retrospectively collected from 2001 to 2019 from the Chang Gung Research Database (CGRD), which is the largest collection of multi-institutional electronic medical records in Taiwan. Children aged 0-20 years with IE were enrolled. We extracted and analyzed the demographic and clinical features, complications, microbiological information, and outcomes of each patient. RESULTS: Of the 208 patients with IE, 114 had heart disease and 94 did not. Compared to those without heart disease, more streptococcal infections (19.3% vs. 2.1%, p < 0.001) and cardiac complications (29.8% vs. 6.4%, p < 0.001) were observed in patients with heart disease. Although patients with heart disease underwent valve surgery more frequently (43.9% vs. 8.5%, p < 0.001) and had longer hospital stays (28.5 vs. 12.5, p = 0.021), their mortality was lower than that of those without heart disease (3.5% vs. 10.6%, p = 0.041). Thrombocytopenia was independent risk factor for in-hospital mortality in pediatric patients with IE (OR = 6.56, 95% CI: 1.43-40.37). CONCLUSION: Among pediatric patients diagnosed with IE, microbiological and clinical features differed between those with and without heart disease. Platelet counts can be used as a risk factor for in-hospital mortality in pediatric patients with IE.

Effect of growth hormone therapy on Taiwanese children with growth hormone deficiency.

BACKGROUND/PURPOSE: Human growth hormone (GH) has been successfully used in children with GH deficiency (GHD). However, there are few published data on the effect of GH in Taiwanese children with GHD. METHODS: We performed a retrospective cohort study to identify factors influencing the effect of GH therapy on ethnic Chinese children with GHD in Taiwan. Idiopathic GHD can be classified into isolated GHD (IGHD) and multiple pituitary hormone deficiency (MPHD). The study looked at the effect of GH on the auxological, biochemical, and imaging parameters of 51 patients (13 girls and 38 boys) in three different diagnostic groups: MPHD (n = 12), IGHD (n = 8), and transient GHD (TGHD; n = 31). TGHD is defined as a GH peak >10 µg/L in re-evaluation by two GH stimulation tests approximately 6 months after discontinuation of GH therapy. RESULTS: The height velocity for first-year GH therapy was 7.61 ± 1.46, 8.14 ± 1.92, and 9.99 ± 2.75 cm/y in the TGHD, IGHD, and MPHD groups, respectively. After post hoc comparison, the MPHD group had a significantly accelerated height velocity in the first year compared to the TGHD group. Correlation analysis showed that a change in height standard deviation score (SDS) in the first year had a significant negative correlation with the following variables: peak GH (r = -0.52, p < 0.001), pretreatment height SDS (r = -0.49, p < 0.001), and height-target height (Ht-TH) SDS (r = -0.49, p < 0.001). Change in height SDS in the first 2 years had a significantly negative correlation with peak GH (r = -0.51, p < 0.001), insulin-like growth factor-1 SDS (r = -0.35, p = 0.022), height SDS (r = -0.60, p < 0.001), difference between bone age and chronological age (r = -0.46, p = 0.001), and Ht-TH SDS (r = -0.50, p = 0.001). After using multiple linear regression, the pretreatment GH peak value was found to be significantly associated with height increments after 1 year of GH treatment (B = -0.07, p = 0.014). CONCLUSION: The administration of GH to children with GHD results in a pronounced acceleration in linear growth during the first year of treatment, especially in those with MPHD. The diagnosis of GHD requires comprehensive auxological, biochemical, and brain magnetic resonance imaging assessment. We also suggest that patients with GHD, specifically IGHD, must undergo a re-evaluation of GH secretion after completion of GH therapy.

[Study of tacrolimus intranasal treatment for allergic asthma in mice].

OBJECTIVE: To explore the efficacy of intranasal treatment by immunosuppressant tacrolimus for allergic asthma and its mechanism in mice. METHODS: 24 female BALB/c mice were randomly divided into 4 groups: group A (negative control), group B (model control), group C (low dose treatment), and group D (high dose treatment). Mice in group A were treated with saline (100 microl). Other groups were sensitized intraperitoneally with allergen extracts of Dermatophagoides farinae (Der f) absorbed to Al(OH)3 at day 0, 7, and 14. From day 28, groups A, B, C, and D were intranasally treated with saline, PBS, 0.01% tacrolimus, and 0.1% tacrolimus, respectively, once per day for 7 d, and followed by intranasal challenge with 50 microl Der f extracts in the mean time. 24 h after the last challenge, the airway hyper-responsiveness (AHR) were detected. At 48 h after the last challenge, the mice were sacrificed, the bronchoalveolar lavage fluid (BALF) was collected, the lungs and spleen were aseptically removed. The total cell number and cell classification of BALF were recorded. The level of interleukin-4 (IL-4), interleukin-5 (IL-5), interferon-gamma (IFN-gamma) in BALF and in spleen cells culture supernatants was detected by ELISA. The lung inflammation and mucus secretion were observed in mice by HE (haematoxylin and eosin) staining and AB (Alcian Blue) staining. RESULTS: Compared with group B, AHR (P < 0.05) and airway inflammation in group D significantly reduced. The number of total cells [(29.92 +/- 5.20) x 10(4)/ml] (P < 0.05) and eosinophils [(4.33 +/- 0.75) x 10(4)/ml] (P < 0.01) in group D greatly decreased than those of group B [(59.33 +/- 5.99) x 10(4)/ml and (22.67 +/- 5.65) x 10(4)/ml]. The level of IL-4 [(22.49 +/- 4.96) pg/ml] (P < 0.05), IL-5 [(43.90 +/- 13.15) pg/ml] (P < 0.01) and IFN-gamma [(10.17 +/- 1.09) pg/ml] (P < 0.05) in BALF significantly decreased (P < 0.05) than those of group B [(57.02 +/- 7.38), (133.49 +/- 15.63) and (15.32 +/- 3.23) pg/ml, respectively]. The level of IL-4 [(22.54 +/- 4.58) pg/ml], IL-5 [(3631 +/- 20.85) pg/ml] and IFN-gamma [(11.28 +/- 1.79) pg/ml] in spleen cell culture supernatant all significantly decreased (P < 0.05) than those of group B [(56.34 +/- 6.21), (72.3 +/- 6.23) and (18.82 +/- 1.88) pg/ml, respectively]. There was no significant difference between group C and group B. CONCLUSION: Tacrolimus shows certain immune therapeutic effect on dust mite sensitized mice, and this effect may be attributed to its inhibition on T lymphocyte factor secretion.

Growth Hormone and Thyroid Function in Children With Attention Deficit Hyperactivity Disorder Undergoing Drug Therapy.

CONTEXT: The trends in hormone indices of children with attention deficit hyperactivity disorder (ADHD) who received long-term medication treatment remains controversial. OBJECTIVE: This prospective study aimed to examine the changes in the growth hormone and thyroid hormone systems among children with ADHD undergoing various medication treatments. METHODS: In total, 118 children who were diagnosed with ADHD and were drug-naive were observed naturalistically over 12 months. Of them, 22 did not receive any medication, while 39, 40, and 17 were treated with low doses of short-acting methylphenidate (MPH) (14 ±â€…6.7 mg/day), osmotic-release oral system (OROS) long-acting MPH (32 ±â€…9.6 mg/day), and atomoxetine (29.2 ±â€…9.7 mg/day), respectively. Blood samples were obtained at both the baseline and the endpoint (month 12) to measure serum levels of insulin-like growth factor 1 (IGF-1), IGF binding protein 3 (IGFBP-3), prolactin, thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and free T4. RESULTS: Trends for IGF-1, IGFBP-3, prolactin, TSH, T3, T4, and free T4 levels were similar among the 4 groups. Changes in serum levels of IGF-1 were positively correlated with changes in height and weight of all the children with ADHD. However, patients who received MPH treatment had less body weight gain than the nonmedicated group. The ratio of MPH doses to body weight was inversely correlated with the increment in height. CONCLUSION: There were no changes in thyroid or growth hormones associated with the low doses of ADHD medications used in this study within 1 year's duration. Nonetheless, patients' growth and the appropriateness of drug dosage should be closely monitored.

The Application of Artificial-Intelligence-Assisted Dental Age Assessment in Children with Growth Delay.

BACKGROUND: This study aimed to reveal the efficacy of the artificial intelligence (AI)-assisted dental age (DA) assessment in identifying the characteristics of growth delay (GD) in children. METHODS: The panoramic films matching the inclusion criteria were collected for the AI model training to establish the population-based DA standard. Subsequently, the DA of the validation dataset of the healthy children and the images of the GD children were assessed by both the conventional methods and the AI-assisted standards. The efficacy of all the studied modalities was compared by the paired sample t-test. RESULTS: The AI-assisted standards can provide much more accurate chronological age (CA) predictions with mean errors of less than 0.05 years, while the traditional methods presented overestimated results in both genders. For the GD children, the convolutional neural network (CNN) revealed the delayed DA in GD children of both genders, while the machine learning models presented so only in the GD boys. CONCLUSION: The AI-assisted DA assessments help overcome the long-standing populational limitation observed in traditional methods. The image feature extraction of the CNN models provided the best efficacy to reveal the nature of delayed DA in GD children of both genders.

Potential disturbance of methylphenidate of gonadal hormones or pubescent development in patients with attention-deficit/hyperactivity disorder: A twelve-month follow-up study.

Several animal or case reports have demonstrated that methylphenidate (MPH) disrupts endogenous gonadal hormones and interferes with the pubescent development of children with attention-deficit/hyperactivity disorder (ADHD). Therefore, this prospective study examined the changes in gonadal hormones and pubescent development in children with ADHD undergoing 12-month MPH treatment. We recruited 146 patients with ADHD (mean age: 8.9 years, 76.7% males) and 70 healthy controls (mean age: 9.2 years, 65.7% males). Blood samples were obtained to measure the serum levels of sex hormone-binding globulin (SHBG), follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, testosterone, free testosterone, and prolactin in each child. The sex maturation of ADHD patients was evaluated using the Tanner Stage. Patients with ADHD (107 received MPH treatment and 39 were under natural observation) were followed up for 12 months, and we re-examined hormone levels and Tanner Stage at the endpoint. During a 12-month follow-up for all ADHD patients, the serum levels of SHBG and progesterone significantly decreased, while LH, FSH, and free-testosterone levels significantly increased. However, the duration, drug formulations, and doses of the MPH treatment did not significantly influence gonadal hormone trends or changes of Tanner Stage. This study provides evidence about gonadal hormone trends and pubescent development in children with ADHD who receive long-term MPH treatment in natural settings. We suggest that MPH treatment at usual doses does not significantly alter gonadal function trends in ADHD patients over the course of one year.

Treatment of Kawasaki Disease: A Network Meta-Analysis of Four Dosage Regimens of Aspirin Combined With Recommended Intravenous Immunoglobulin.

Aspirin was once believed to reduce the mortality of Kawasaki disease (KD) due to its effect on the thrombotic occlusion of coronary arteries. However, conflicting evidence has been found regarding aspirin treatment and its benefit in patients with acute KD. We compared the efficacy of different aspirin doses in acute KD. A literature search of PubMed, EMBASE, and Cochrane databases was conducted to identify studies comparing different doses of aspirin for acute KD. The primary outcome of interest was coronary artery lesions (CAL). We used random-effects network meta-analysis. Six retrospective studies, including 1944 patients receiving aspirin in doses of 0, 3-5, 30-50, or 80-100 mg/kg/day, were selected. The risks of CAL were not significantly different for the various doses of aspirin compared to the placebo: odds ratio (OR) was 1.10 [95% confidence interval (CI): 0.70-1.71] for patients with aspirin 3-5 mg/kg/day; OR = 1.23 (95% CI: 0.67-2.26) for aspirin 30-50 mg/kg/day, and OR = 1.59 (95% CI: 0.74, 3.421) for 80-100 mg/kg/day. The P-score ranged from 0.76 for placebo to 0.19 for aspirin 80-100 mg/kg/day. The different doses of aspirin exhibited no significant difference with regard to the efficacy of CAL or with the secondary outcomes of intravenous immunoglobulin resistance or hospital stays for acute KD. Therefore, we found that treatment without any aspirin is not inferior to other doses of aspirin and can also slightly reduce the risk of CAL.

Stagonosporopsis pogostemonis: A Novel Ascomycete Fungus Causing Leaf Spot and Stem Blight on Pogostemon cablin (Lamiaceae) in South China.

Pogostemon cablin is one of the well-known Southern Chinese medicinal plants with detoxification, anti-bacterial, anti-inflammatory, and other pharmacological functions. Identification and characterization of phytopathogens on P. cablin are of great significance for the prevention and control of diseases. From spring to summer of 2019 and 2020, a leaf spot disease on Pogostemon cablin was observed in Guangdong Province, South China. The pathogen was isolated and identified based on both morphological and DNA molecular approaches. The molecular identification was conducted using multi-gene sequence analysis of large subunit (LSU), the nuclear ribosomal internal transcribed spacer (ITS), beta-tubulin (ß-tubulin), and RNA polymerase II (rpb2) genes. The causal organism was identified as Stagonosporopsis pogostemonis, a novel fungal species. Pathogenicity of Stagonosporopsis pogostemonis on P. cablin was fulfilled via confining the Koch's postulates, causing leaf spots and stem blight disease. This is the first report of leaf spot diseases on P. cablin caused by Stagonosporopsis species worldwide.

Individuals at high risk for psychosis experience more childhood trauma, life events and social support deficit in comparison to healthy controls.

Evidence for psychological risk factors on prodromal state of psychosis remained limited and inconsistent. This study aimed to investigate childhood trauma, life events and social support in subjects with high risk for psychosis (HR), first episode psychosis with schizophrenia (FEP) and healthy control (HC). In the study, 56 FEP, 83 HR and 61 HC underwent face-to-face clinical interview and psychological assessment, including Childhood Trauma Questionnaire (CTQ), Life Events Scale (LES) and Perceived Social Support Scale (PSSS). The results showed that in univariate analysis, HR individuals had more childhood trauma, more recent life events and less social support than HC group, and these findings were also supported by ANCOVA analysis except for the results related to social support after taking age, education, marital and employment status as covariates. Logistic regression analysis revealed that HR group was significantly associated with more childhood trauma, poorer overall function and unmarried state than HC group after controlling the interfering factors. HR group was similar with FEP group in these assessments. In conclusion, HR individuals experienced more childhood trauma, life events and social support deficit than HC group, which may be risk factors of conversion to psychosis. Further explorations are warranted to develop optimal psychosocial interventions.

[Study on preparation and determination of Liaojin plastics].

OBJECTIVE: To establish the optimum preparation and determination method of Liaojin plastics through screening different factors. METHODS: The Orthogonal Test was applied to optimize the best preparation technology, and the content of peoniflorin in Liaojin plastics was determined by HPLC. RESULTS: The best matrix proportion of plastics was PVA-124 : alcohol : acetone : distilled water = 1 : 4 : 2 : 10; The average recovery of plastics was 98.56%, RSD was 1.66% (n = 9), and the average content of six samples was 0.6817 mg/g, RSD was 1.44%. CONCLUSION: The good quality plastics can be produced through this process. HPLC determination method is simple, reliable and can be used in the quality control of Liaojin plastics.

Prenatal Dexamethasone Exposure Programs the Development of the Pancreas and the Secretion of Insulin in Rats.

BACKGROUND: There is increasing epidemiological evidence indicating that many chronic diseases originate during early life, even before birth, through what are termed fetal programming effects. Prenatal glucocorticoid is frequently used clinically to accelerate the maturation of the lung, but its long-term effects remain unclear. METHODS: We gave pregnant Sprague-Dawley rats either intraperitoneal dexamethasone (0.1 mg/kg body weight) or vehicle at Gestational Days 14-20 and assessed the effects to pancreas at Postnatal Days 7 and 120. RESULTS: We found fewer pancreatic ß cell fractions (0.31±0.05 % vs. 0.49±0.05 %, p=0.013) and tissues (0.0017±0.0002 % vs. 0.0025±0.0002 %, p=0.042) and decreased secretion of insulin in response to a glucose challenge at Postnatal Day 105 (1.00±0.19 ng/mL vs. 1.57±0.17 ng/mL at the 15-minute time-point, p=0.046) in rats treated prenatally with dexamethasone. At Postnatal Day 7 in rats treated prenatally with dexamethasone, the expression of pancreatic duodenal homeobox gene-1 and V-maf avian musculoaponeurotic fibrosarcoma oncogene homolog A was lower than that in the rats in the Vehicle group (0.22±0.07 vs. 1.00±0.41 fold, p=0.01, 0.20±0.12 vs. 1.00±0.35 fold, p=0.01) while the histone deacetylases activity (54.2±3.7 ng/h/mL vs. 37.6±3.5 ng/h/mL, p=0.012) and 8-hydroxy-2-deoxyguanosine staining (1.34±0.01 vs. 1.00±0.02 fold, p<0.01) were higher. CONCLUSION: Prenatal dexamethasone exposure affects early postnatal gene expression related to pancreas development and may exert an effect on ß-cell development at 120 postnatal days.
