Objective: To explore the moderating effect of parenting style on parental involvement in education and aggressive behavior of nursery child, so as to provide a reference basis for promoting the healthy development of nursery child behavior. Methods: From March 2023 to February 2024, through a stratified cluster random sampling method, 1 509 parents from 12 kindergartens in Heilongjiang, Shanxi, Shandong, Jiangsu and Guangdong provinces were investigated by using Parental Involvement Questionnaire, Parental Reported Aggression Behavior Subscale of Child Behavior Checklist, Parenting Styles, and Dimensions Questionnaire. Mann-Whitney test and Kruskal-Wallis H test were used for group comparison, and Spearman correlation analysis was used to explore the relationship between parental involvement, aggressive behavior in nursery child and parenting style. Stratified linear regression analysis was used to investigate the moderating effect of parenting style on parental involvement and aggressive behavior in young children. Results: There was a significant positive correlation of aggressive behavior in nursery child with authoritarian parenting styles and indulgent parenting styles ( r=0.53, 0.52, P <0.01). Aggression behavior in nursery child was negatively associated with authoritative parenting styles, home communication, in school participation, and in home participation ( r = -0.15 , -0.12, -0.09, -0.10, P <0.01). The regulatory effect results showed that authoritative and authoritarian parenting style had a statistically significant moderating effect on parental involvement and aggressive behavior in nursery child ( β=0.12, -0.11, P < 0.01), while permissive parenting styles had no statistically significant moderating effect on parental involvement and aggressive behavior ( β= -0.01, P >0.05). Conclusions Parents involvement in education is closely related to nursery child s aggressive behavior. The authoritative and authoritarian parenting styles moderate the relationship between parental involvement and aggressive behavior in nursery child, while the permissive parenting styles does not.

Objective To investigate the therapeutic effect and mechanisms of live combined bifidobacterium and lactobacillus tablets on slow transit constipation(STC)rats.Methods A total of 30 SPF grade Wistar adult female rats were blinded and divided into control group,model group,live combined bifidobacterium and lactobacillus tablets low-dose(0.270g/kg),live combined bifidobacterium and lactobacillus tablets medium dose group(0.540g/kg),live combined bifidobacterium and lactobacillus tablets high-dose group(1.080g/kg),and positive drug group(prucalopride succinate tablet)(0.180mg/kg),with 5 rats in each group.A rat model of STC was established by gavage of loperamide hydrochloride.After successful modeling,medication was administered by gavage for 14 consecutive days on the basis of continued modeling.Observe the changes in general physical signs,fecal water content,and calculate intestinal motility in each group of rats.Using HE staining to observe pathological changes in colon tissue,immunohistochemical methods were used to detect the protein expression of receptor tyrosine kinase(c-Kit),5-hydroxytryptamine(5-HT),5-hydroxytryptamine 3 receptor(5-HT3R),and 5-hydroxytryptamine 4 receptor(5-HT4R)in rat colon tissue.Results Compared with control group,frequency of defecation,fecal water content and intestinal propulsion speed of STC model rats were significantly decreased.The expression levels of proteins such as c-Kit,5-HT,5-HT3R,and 5-HT4R in intestinal tissues were significantly reduced in STC model rats.Compared with STC model group,rats treated with low,medium and high doses of live combined bifidobacterium and lactobacillus tablets and positive drug groups showed a significant increase in bowel frequency,fecal water content,and intestinal motility after intervention.Compared with STC model group,frequency of defecation,fecal water content,intestinal propulsion rate and protein expression of c-Kit,5-HT,5-HT3R and 5-HT4R in rat intestinal tissues were significantly increased after intervention of live combined bifidobacterium and lactobacillus tablets low,medium and high dose groups.Conclusion This study confirms that probiotic preparation live combined bifidobacterium and lactobacillus tablets effectively improves slow transit constipation by promoting the proliferation of Cajal interstitial cells in the colon,increasing the expression of 5-HT,5-HT3R,and 5-HT4R,enhancing intestinal peristalsis,and achieving the therapeutic effect on STC rats.

Atopic dermatitis (AD) is a common chronic inflammatory disease that often coexists with atopic diseases such as asthma, allergic rhinitis, and food allergies. In recent years, more and more studies have shown that AD is associated with various diseases such as cardiovascular diseases, autoimmune diseases, and mental disorders, which exacerbate the disease burden on patients with AD and severely affect their quality of life. This review summarizes AD-associated comorbidities reported in previous literature, analyzes their possible common pathogenesis, and explores potential treatments.

Objective To compare the effects of ginsenosides Rg1 and Rb1 on depression-and anxiety-like behaviors in chronic unpredictable stress-induced rats.Methods Seventy male SPF grade SD rats were tested for sugar and water preference after 5 days of adaptation and divided into seven groups according to their preference index:a control group,model group,fluoxetine hydrochloride group,ginsenoside Rg1 24 mg/kg group,ginsenoside Rg1 48 mg/kg group,ginsenoside Rb1 33 mg/kg group,and ginsenoside Rb1 67 mg/kg group.All rats,except for the control group,were subjected randomly to one or two different stimulating factors every day for a total of 35 days.On the 36th day,behavioral experiments including sugar and water preference,open field,novel environment feeding inhibition,elevated cross maze,and forced swimming experiments were conducted to investigate the anti-depression and anti-anxiety effects of the treatments.Serum and hippocampal levels of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-α and serum corticosterone were measured by enzyme-linked immunosorbent assay.Results Compared with the model group,ginsenoside Rg1 and Rb1 significantly increased sucrose consumption in the sucrose preference test and decreased immobility in the forced swimming test.Ginsenoside Rg1(48 mg/kg)significantly reduced the latency to eat in the novelty-suppressed feeding test,and ginsenoside Rg1(24 and 48 mg/kg)significantly increased the percentage of open arm entries and time in the elevated cross maze test.Serum corticosterone levels were significantly decreased in the ginsenoside Rg1 and Rb1 groups,serum IL-1β and IL-6 levels were significantly decreased in the ginsenoside Rg1(48 mg/kg)group,serum TNF-α and IL-6 levels were significantly decreased in the ginsenoside Rb1(33 mg/kg)group,and IL-1β,IL-6,and TNF-α levels in the hippocampus were significantly decreased in the ginsenoside Rg1(48 mg/kg)and Rb1(67 mg/kg)groups.Conclusions Both ginsenosides can regulate the hypothalamic-pituitary-adrenal axis and inhibit neuroinflammation,improving depression-and anxiety-like behaviors in rats induced by chronic unpredictable stress.Ginsenoside Rg1 has a significantly better anti-anxiety effect than Rb1.

BACKGROUND: The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis. METHODS: In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis. RESULTS: A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP. CONCLUSIONS Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

Purpose: There is no optimal prognostic model for T-cell lymphoblastic lymphoma (T-LBL). Here, we discussed the predictive value of total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) measured on 18F-fluorodeoxyglucose positron emission tomography–computed tomography (PET-CT) in T-LBL. Materials and Methods: Thirty-seven treatment naïve T-LBL patients with PET-CT scans were enrolled. TMTV was obtained using the 41% maximum standardized uptake value (SUVmax) threshold method, and TLG was measured as metabolic tumor volume multiplied by the mean SUV. Progression-free survival (PFS) and overall survival (OS) were analyzed by Kaplan-Meier curves and compared by the log-rank test. Results: The optimal cutoff values for SUVmax, TMTV, and TLG were 12.7, 302 cm3, and 890, respectively. A high SUVmax, TMTV, and TLG indicated a shorten PFS and OS. On multivariable analysis, TMTV ≥ 302 cm3, and central nervous system (CNS) involvement predicted inferior PFS, while high SUVmax, TLG and CNS involvement were associated with worse OS. Subsequently, we generated a risk model comprising high SUVmax, TMTV or TLG and CNS involvement, which stratified the population into three risk groups, which had significantly different median PFS of not reached, 14 months, and 7 months for low-risk group, mediate-risk group, and high-risk group, respectively (p < 0.001). Median OS were not reached, 27 months, and 13 months, respectively (p < 0.001). Conclusion Baseline SUVmax, TMTV, and TLG measured on PET-CT are strong predictors of worse outcome in T-LBL. A risk model integrating these three parameters with CNS involvement identifies patients at high risk of disease progression.

The traditional view is that breast reconstruction is not an option for day surgery center. As a result, few hospitals in the world conduct this operation in day surgery center. Endoscopic breast reconstruction with liposuction and robot-assisted breast reconstruction are minimally invasive surgeries for breast cancer patients, but they cannot be carried out in the day surgery center due to long operation time. The novel endoscopic-assisted immediate implant-based breast reconstruction after nipple sparing mastectomy through a single axillary incision for breast cancer patients has been successfully conducted in the day surgery center in our hospital due to short operation time and small trauma. Standardized management of the complete process from the patient selection to follow-up after discharge brings rapid recovery and few complications. At the same time, the development of endoscopic surgery makes the breast almost scarless and improves aesthetic results. Therefore, the mode of endoscopic-assisted reconstruction in the day surgery center of our hospital is expected to be popularized in the whole country.
