Objective: To explore the relationship between behavioral problems and accidental injuries among preschoolers, and to provide evidence for the targeted prevention of children s accidental injuries. Methods: During September to October 2019, parent of 2 062 children aged 3 to 6 selected from 8 kindergartens in Hefei through stratified clustering method were investigated. The prevalence of accidental injuries and behavioral problems among preschoolers was collected by questionnaire survey. Results: The prevalence of accidental injury during the past year was 14.55%(300), and behavioral problems 14.21%(293). Total rate of behavioral problems and rate of each dimensions in children with accidental injury were 32.67%, 2.33%, 19.67%, 15.00%, 2.00%, 1.00 % and 5.00%, compared to 11.07%, 0.45%, 6.41%, 4.88%, 0.40%, 0.17% and 0.79% in children without accidental injury ( χ 2=98.11, 12.54, 58.90, 44.12, 10.51, 6.08, 32.68, P <0.01). Multivariate Logistic regression analysis showed that psychosomatic problems( OR =3.13, 95% CI =2.11-4.66), learning problems( OR =2.73, 95% CI =1.86-3.99), abnormal hyperactivity index ( OR =3.16, 95% CI =1.40-7.14) and left behind children ( OR =1.53, 95% CI =1.13-2.07) were associated with higher risk of accidental injuries( P <0.05). Conclusion Behavioral problems are significantly associated with unintentional injuries among preschool children, which deserved further attention and intervention when formulating prevention and control measures for childhood accidental injury.

Objective: To explore the relationship between father s emotional symptoms with offspring s emotional and behavioral problems, so as to provide reference for the prevention and intervention of emotional and behavioral problems in preschool children. Methods: Using the method of multi stage sampling, two kindergartens from each of the two counties, two districts and two development zones were selected from Hefei during February to April 2023. A total of 3 672 children aged 3 to 6 years old and their fathers were selected from 12 kindergartens. Fathers filled out the Depression Anxiety and Stress Scale (DASS-21) and mothers filled out the Strength and Difficulty Questionnaire (SDQ). Multivariate Logistic regression model was established to analyze the relationship between father s emotional symptoms and preschool children s emotional and behavioral problems. Results: The detection rate of emotional and behavioral problems in preschool children was 18.65%, and the detection rates of stress, anxiety and depression in fathers were 4.82%, 10.05% and 6.64%, respectively. Multivariate Logistic regression model analysis showed when fathers had negative emotions of stress, anxiety and depression, the detection rate of emotional and behavioral problems in their offspring was higher than children with father without negative emotion group ( OR =1.77-2.13, P <0.01). Father s stress symptoms were associated with increased risk of emotional and behavioral problems in boys, while father s anxiety and depressive symptoms were associated with increased risk of emotional and behavioral problems in boys and girls ( OR =1.45-2.69, P <0.05). Father s stress symptoms were associated with increased risk of emotional and behavioral problems in the first child, while father s anxiety and depressive symptoms were associated with increased risk of emotional and behavioral problems in the first child, second child and above ( OR =1.81-2.49, P <0.05). Conclusions Father s negative emotional symptoms are important factors affecting preschool children s emotional and behavioral problems. Early detection and targeted intervention of father s negative emotional symptoms are beneficial to the prevention and control of preschool children s emotional and behavioral problems.

Taking G University as an example, through empirical research, this study finds out that the motivation of teachers on medical education research is insufficient; the support and incentive for young and middle-aged teachers to participate in higher education research is insufficient; and universities lack of an efficient higher education research organization system; the social influence of medical research and education is not enough, etc. We call on independent medical universities to further improve the higher education research organization system, change the current situation and increase the support and incentives for young and middle-aged teachers to participate in higher education research, guide teachers to summarize the characteristics of medical education teaching, improve the quality of medical personnel training, and expand the influence of medical education research.

Hyperhidrosis is a disease in which excessive sweat is secreted,resulting in an abnormal increase in systemic or local perspiration.In traditional Chinese medicine,hyperhidrosis belongs to the category of sweating disease.It is caused by an imbalance between yin and yang and abnormal excretion of body fluid.Many doctors treat the sweating disease from the perspective of heart,lung,and kidney;in contrast,we discuss the etiology and pathogenesis of hyperhidrosis from the perspective of liver and spleen,explain the significance of harmonizing the liver and spleen to improve the sweating disease,and put forward the key pathogenic factors of stagnation liver qi and spleen deficiency,and disharmony between nutrient qi and defensive qi,and the imbalance between yin and yang are the key pathogenic factor.Most of the clinical treatment start from the liver and spleen.The main treatment principle is based on soothing the liver and relieving depression,invigorating the spleen and nourishing blood,and regulating and harmonizing the nutrient qi and defensive qi,paying attention to the relationship between qi and blood in zangfu organs,invigorating the spleen and replenishing qi to consolidate its foundation,soothing the liver and relieving depression to regulate its qi,and invigorating qi and blood and perspiration.Treatment can be supplemented with Xiaoyao Powder plus-minus,mainly to strengthen liver wood and spleen soil,acquire nourishment,smooth qi,nourish the five zang,reconcile qi and blood,enhance physical strength and peace of mind,ensure sufficient qi to arrest sweating,coordinate the liver and spleen,balance the ascending and descending phases,and harmonize the five zang organs.

Objective:To analyze the efficacy of laparoscopic radical surgery, compared to open surgery, for incidental gallbladder cancer following cholecystectomy.Methods:Clinical data of 106 patients with incidental gallbladder cancer treated at the Second Affiliated Hospital Zhejiang University School of Medicine from April 2010 to February 2018 were retrospectively analyzed, including 66 males and 40 females, aged (64.7±7.9) years old. According to surgical approach, patients were divided into the laparoscopic group ( n=45) and open group ( n=61). Perioperative data, including intraoperative blood loss, postoperative hospital stay, and postoperative complications, were compared between the groups. Follow-ups were conducted via outpatient visits or telephone reviews. Survival analysis was performed using the Kaplan-Meier method, and the survival rates were compared using the log-rank test. Results:All 45 patients in the laparoscopic group successfully underwent the surgery without conversion to open surgery. Compared to the open group, the laparoscopic group had a reduced intraoperative blood loss [(100±25) ml vs. (200±46) ml] and a shortened postoperative hospital stay [3(2, 5) d vs. 5(4, 7) d] (both P<0.05). The postoperative complication rates were 6.7% (3/45) in the laparoscopic group and 13.1% (8/61) in the open group ( χ2=4.16, P=0.041). The cumulative survival rate after radical surgery for incidental gallbladder cancer was better in the laparoscopic group ( χ2=4.58, P=0.032). Conclusion:Compared to open surgery, laparoscopic radical surgery for incidental gallbladder cancer showed benefits in intraoperative blood loss, postoperative hospital stay, complication rates, and cumulative survival.

Objective:To provide epidemiological data and clinical evidence for cosmetic adverse reactions.Methods:A retrospective clinical analysis was carried out on a total 820 outpatients (23 males and 797 females) suspected to be with cosmetic adverse reactions from January 2014 - October 2017, and average age of these patients was 7~75 (32.66±8.09) years. Suspicious cosmetics patch tests were performed in some patients. Suspicious cosmetics patch tests were performed in 687 patients.Results:Among 820 patients with cosmetic adverse reactions, women accounted for 97.20% and men accounted for 2.80%. Age distribution was most common among young people aged 21-40 years, accounting for 71.34%. The highest level of education was higher education, accounting for 59.69%. Occupational distribution was most commonly concentrated in employees and unemployed persons, accounting for 28.54% and 18.66%, respectively. A history of cosmetics allergies accounted for 17.28%. Cosmetic contact dermatitis was the most common clinical type of cosmetic adverse reactions, accounting for 92.70%. A total of 1682 suspected pathogenic cosmetics were involved. The positive rate of the cosmetic original patch test was 42.39%. Among the cosmetics with a positive patch test, moisturizing, anti-wrinkle and whitening freckle cosmetics accounted for the highest proportion, 31.59%, 15.09%, and 12.68%, respectively.Conclusions:Cosmetic contact dermatitis is the most common type of cosmetic adverse reaction. Patch testing is helpful in identifying the contact allergens in cosmetic adverse reaction.

ObjectiveTo determine the influence of Buzhong Yiqitang on miRNA expression in thyroid tissues of mice with autoimmune thyroiditis （AIT）. MethodThirty female 8-week-old NOD.H-2^h4 mice were randomly assigned into normal control group， model group， and Buzhong Yiqitang group （BG）， 10 in each group. Mice were subjected to a diet containing 0.05% sodium iodide for 8 weeks to build the AIT mouse model. After 8 weeks of administration （ig）， samples were collected. A thyroid biopsy was performed on each group of mice， and differential miRNAs in thyroid tissues from each group of mice were analyzed based on experimental validation and bioinformatics. ResultCompared with the conditions of normal control group， thyroid lymphocytes had significant inflammatory infiltration， and there was an increase in serum TgAb level and interleukin（IL）-6 and IL-17 expression and a decrease in IL-1β expression in mice of the model group （P<0.05， P<0.01）. In addition， 154 differentially expressed miRNAs were found. Compared with the conditions of model group， the degree of thyroid tissue inflammation was alleviated， and serum TgAb level， and IL-1β， IL-6 and IL-17 expression of mice treated with the Buzhong Yiqitang were reduced （P<0.05， P<0.01）. Additionally， 112 differentially expressed miRNAs were identified in the BG group. Validation using real-time polymerase chain reaction（Real-time PCR） showed the same trend for miR-326-3p， miR-128-3p， miR-223-5p， miR-141-3p， miR-871-3p， and miR-204-3p as that obtained from miRNA sequencing. In particular， gene ontology（GO） functions were enriched for regulation of T cell activation， oxidative stress， and miRNA binding. Pathways identified by Kyoto encyclopedia of genes and genomes（KEGG）database tended to be enriched in phosphatidylinositol 3-kinases（PI3K）/protein kinase B（Akt）， mitogen-activated protein kinase（MAPK）， and cyclic adenosine monophosphate（cAMP） signaling pathways. Based on miRNA prediction differences， three key genes were identified： SMAD3， JAK2， and STAT3. ConclusionBushong Yiqitang might treat autoimmune thyroiditis by regulating 6 miRNAs.
