MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Objective:To investigate the status quo and influencing factors of social isolation of parents of children with autism spectrum disorder in order to provide theoretical basis for clinical intervention measures.Methods:A total of 340 parents of children with autism spectrum disorder who visited the Children′s Developmental Behavior Center of Third Affiliated Hospital of Sun Yat sen University were selected by the convenience sampling method as research objects during July to November 2023. A cross-sectional survey was investigated by a general information questionnaire, General Alienation Scale, Social Avoidance and Distress Scale, Affiliate Stigma Scale, Family APGAR Index, Chinese Simplified Version of Social Support Scale, and Social Responsiveness Scale.Results:A total of 323 valid questionnaires were collected, including 235 mothers and 88 fathers; 33 individuals aged 25-29 years, 233 individuals aged 30-39 years, and 57 individuals aged 40-60 years. The subjective social isolation score of parents of children with autism spectrum disorder was 33.24 ± 4.92 and the objective social isolation score was 4.00(2.00,7.00). The results of multiple linear regression analysis showed that the subjective social isolation of parents of children with autism spectrum disorder was influenced by factors including self-assessed health status, whether they worked full-time or not, whether they were satisfied with the division of labor in the family caring for their children, affiliate stigma, family care, and social support (all P<0.05); and the objective social isolation of parents was influenced by factors including the severity of autism symptoms, self-assessed health status, affiliate stigma, and family care (all p<0.05). Conclusions:Parents of children with autism spectrum disorder had some degree of social isolation, and the level of subjective social isolation was higher than objective social isolation. Healthcare professionals should pay attention to parents of autistic children who have high levels of symptom severity, poor self-rated health, do not work full-time, and are dissatisfied with the division of labor in the family caring for their child, and take measures to reduce the affiliate stigma, and to increase the level of family care and social support, so as to improve the social isolation of parents of children with autism spectrum disorder.

Objective:To evaluate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of solid intraductal papilloma (sIDP) of breast by comparing with fibronenoma of breast (FA).Methods:The CEUS data of 62 cases of sIDP patients and 94 cases of FA patients that confirmed by pathology in the First Affiliated Hospital of Soochow University from October 2016 to January 2021 were retrospectively analyzed. The patients were divided into sIDP group and FA group according to the pathological results. The enhancement speed, enhancement degree, enhancement uniformity, whether the edge after enhancement was polished, whether the enhancement range was enlarged, whether there was a ring unenhanced area in the inner edge of the lesion and whether the inner edge of the unenhanced area was polished were observed in the two groups. SonoLiver software was used to perform offline analysis of the dynamic process of CEUS in the two groups respectively, the enhancement sequence diagram of the lesions was obtained. The pathological result was taken as the gold standard, univariate analysis was applied, and the parameters with statistical significance between the two groups were included in multivariate Logistic regression analysis to establish a differential diagnosis model. The diagnostic efficiency of sIDP was analyzed by ROC curve and diagnostic model.Results:Compared with the FA group, CEUS in the sIDP group mostly showed fast forward, high enhancement, and the enhancement sequence was mostly centrifugal. After CEUS, the lesion edges in the sIDP group were mostly accompanied by unenhanced areas and the inner edges of the unenhanced areas were not intact, and the differences between the two groups were statistically significant (all P<0.05). Binary Logistic regression showed that age, enhancement degree and enhancement order were independent risk factors for sIDP diagnosis. The ROC curve showed that the area under the ROC curve of age, enhancement degree and enhancement sequence combined for the diagnosis of sIDP was 0.874 (95% CI=0.812-0.922), the accuracy was 76.9%, the sensitivity was 67.7%, the specificity was 83.0%, the positive predictive value was 72.4%, and the negative predictive value was 79.6%. Conclusions:There are significant differences in age, enhancement degree and enhancement sequence between sIDP and FA patients. The three-parameter combination can improve the diagnostic efficiency of sIDP.

Objectives:To discuss the inhibitory effect of Lactobacillus reuteri on the replication of rotavirus(RV)strain SA11 in vivo and in vitro,and to clarify its effect on the expression of related immune factors.Methods:For in vitro experiments,Lactobacillus reuteri was cultured and identified,and the standard curve and growth curve were plotted to screen the optimal time and concentration for Lactobacillus reuteri cultivation.The cells were infected with Lactobacillus reuteri at the concentrations of 5×108,10×108,50×108,100×108,200×108,and 500×108 CFU·mL-1,and the surival rates of Caco-2 cells were detected by trypan blue staining method.Various concentrations of Lactobacillus reuteri were co-incubated with RV in vitro and applied to the Caco-2 cells.The cells were divided into negative control group(NC group),positive control group(PC group),and 107,108,109,and 1010 CFU·mL-1 Lactobacillus reuteri groups.Immunofluorescence focus method was used to detect the viral titers in the Caco-2 cells after treated with Lactobacillus reuteri and real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the copy numbers of RV VP6 gene in the Caco-2 cells after treated with various concentrations of Lactobacillus reuteri.In in vivo experiments,25 litters of SPF suckling mice were divided into control group,RV group(infected with SA11 strain),Ab-NC group(treated with antibiotic to deplete gut microbiota),Ab-RV group(depleting gut microbiota and then infected with SA11 strain),and Ab-Lac-RV group(depleting gut microbiota,treated with Lactobacillus reuteri,and then infected with SA11 strain).The fecal samples were collected on days 2,4,6,8,and 10 gavage,colon tissue sample were collected on day 4 of and RT-qPCR method was used to detect the copy numbers of RV VP6 gene in feces and the mRNA expression levels of interleukin(IL)-1β,IL-8,IL-10,interferon-γ(IFN-γ),and tumor necrosis factor-α(TNF-α)in colon tissue of the suckling mice in vartious groups.Results:The Lactobacillus reuteri grew well,with round,smooth,and milky white convex colonies and neat edges.After Gram staining,the bacteria appeared purple,irregular,and square-shaped rods.16SrDNA sequencing showed 99%sequence homology,indicating successful activation of Lactobacillus reuteri.The number of live Lactobacillus reuteri was linearly related to the absorbance(A)value,and the standard curve for regression analysis was Y=0.437 5X+0.000 6,R2=0.999 4.During the 0-2 h cultivation period,the bacteria were at the logarithmic growth phase with slow growth;from 2-14 h,the bacteria grew rapidly and stabilized at 14-16 h,reaching the growth rate peak at 16 h,after which they entered the decline phase.Infection with Lactobacillus reuteri at concentrations of 5×108,10×108,50×108,100×108,and 200×108 CFU·mL-1 resulted in the survival rates of Caco-2 cells were all>90%,so these concentrations were selected for the further experiments.Compared with PC group,the copy numbers of RV VP6 gene in the Caco-2 cells in 5×108,10×108,50×108,100×108,and 200×108 CFU·mL-1 Lactobacillus reuteri groups were significantly decreased(P<0.01).Compared with PC group,the viral titers in the Caco-2 cells in 107,108,109,and 1010 CFU·mL-1 Lactobacillus reuteri groups were significantly decreased(P<0.01).Compared with control group,the numbers of gut microbiota colonies in Ab-NC,Ab-RV,and Ab-Lac-RV groups were significantly decreased,indicating successful depletion of gut microbiota in the suckling mice.On days 2 and 4 after gavage,the RV VP6 gene copy number in the feces in Ab-RV group was significantly lower than that in RV group(P<0.05).On days 4,6,8,and 10 after gavage,the RV VP6 gene copy number in the feces in Ab-Lac-RV group was significantly lower than that in Ab-RV group(P<0.05).Compared with control group,the expression levels of IL-1β,IL-10,IFN-γ,and TNF-α mRNA in colon tissue in Ab-RV and Ab-Lac-RV groups were significantly increased(P<0.05 or P<0.01),while the expression level of IL-8 mRNA was significantly decreased(P<0.05),and the expression level of IL-10 mRNA in colon tissue in Ab-LAC-RV group was significantly increased(P<0.01).Conclusion:Lactobacillus reuteri may inhibit the RV replication by upregulating the expressions of IL-1β,IL-10,IFN-γ,and TNF-α mRNA and downregulating the expression of IL-8 mRNA.

Background: Dust generated during the processing of building materials enterprises can pose a serious health risk. The study aimed to compare and analyze the results of ART and the Monte Carlo model for the dust exposure assessment in building materials enterprises, to derive the application scope of the two models. Methods: First, ART and the Monte Carlo model were used to assess the exposure to dust in each of the 15 building materials enterprises. Then, a comparative analysis of the exposure assessment results was conducted. Finally, the model factors were analyzed using correlation analysis and the scope of application of the models was determined. Results: The results show that ART is mainly influenced by four factors, namely, localized controls, segregation, dispersion, surface contamination, and fugitive emissions, and applies to scenarios where the workplace information of the building materials enterprises is specific and the average dust concentration is greater than or equal to 1.5 mg/m3. The Monte Carlo model is mainly influenced by the dust concentration in the workplace of building materials enterprises and is suitable for scenarios where the dust concentration in the workplace of the building materials enterprises is relatively uniform and the average dust concentration is less than or equal to 6mg/m3. Conclusion ART is most accurate when workplace information is specific and average dust concentration is > 1.5 mg/m3; whereas, The Monte Carlo model is the best when dust concentration is homogeneous and average dust concentration is < 6 mg/m3.

Objective:To explore the difference of the vessel and plaque characteristics, myocardial perfusion and cardiac function between patients with ischemia with non-obstructive coronary artery disease (INOCA) and obstructive coronary artery disease (CAD).Methods:From July 2021 to June 2022, 101 patients with angina were referred to dynamic computed tomography myocardial perfusion (CTP) and coronary computed tomography angiography (CCTA) and retrospectively included in our hospital. Based on the results of CTP and CCTA, patients were divided into INOCA (27 cases), moderate obstructive CAD (26 cases) and severe obstructive CAD (48 cases). The anatomical coronary artery stenosis, plaque characteristics and myocardial perfusion features of all patients were analyzed. Furthermore, left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were obtained on full-phase reconstruction CCTA image by using Medis Suite 3.2 postprocessing software. Multigroup analysis used one way ANOVA or Kruskal Wallis H test. Results:Patients with INOCA were younger than patients with moderate and severe obstructive CAD ( P<0.001). INOCA patients (7.4%, 2/27) had lower rate of positive remodeling than both moderate (57.7%, 15/26, P<0.001) and severe obstructive CAD patients (33.3%, 16/48, P=0.017). The percentage of ischemic myocardium volume in patients with INOCA were similar with those in patients with severe CAD (all P>0.05), but significantly higher than those in patients with moderate CAD (all P<0.05). No significant difference in terms of GLS was detected between patients with INOCA [-17.4% (-21.6%, -11.6%)] and severe CAD [-17.6% (-21.9%, -14.8%), P=0.536], however, patients both with INOCA and severe CAD also had higher GLS than patients with moderate obstructive CAD [-22.3% (-29.8%, -19.0%), all P<0.05]. Conclusions:Based on"one-stop-shop"CTP combined with CCTA imaging, early cardiac functional changes including abnormal myocardial perfusion and myocardial strain in INOCA patients were similar to those in patients with severe obstructive CAD and more severe than those in patients with moderate obstructive CAD.

Immunoglobulin G4-related sialadenitis (IgG4-RS) is an immune-mediated fibro-inflammatory disease and the pathogenesis is still not fully understood. The aim of this study was to explore the role and mechanism of interleukin-13 (IL-13) in the cellular senescence during the progress of IgG4-RS. We found that the expression of IL-13 and IL-13 receptor α1 (IL-13Rα1) as well as the number of senescent cells were significantly higher in the submandibular glands (SMGs) of IgG4-RS patients. IL-13 directly induced senescence as shown by the elevated activity of senescence-associated β-galactosidase (SA-β-gal), the decreased cell proliferation, and the upregulation of senescence markers (p53 and p16) and senescence-associated secretory phenotype (SASP) factors (IL-1β and IL-6) in SMG-C6 cells. Mechanistically, IL-13 increased the level of phosphorylated signal transducer and activator of transcription 6 (p-STAT6) and mitochondrial-reactive oxygen species (mtROS), while decreased the mitochondrial membrane potential, ATP level, and the expression and activity of superoxide dismutase 2 (SOD2). Notably, the IL-13-induced cellular senescence and mitochondrial dysfunction could be inhibited by pretreatment with either STAT6 inhibitor AS1517499 or mitochondria-targeted ROS scavenger MitoTEMPO. Moreover, IL-13 increased the interaction between p-STAT6 and cAMP-response element binding protein (CREB)-binding protein (CBP) and decreased the transcriptional activity of CREB on SOD2. Taken together, our findings revealed a critical role of IL-13 in the induction of salivary gland epithelial cell senescence through the elevated mitochondrial oxidative stress in a STAT6-CREB-SOD2-dependent pathway in IgG4-RS.

With the advent of laparoscopic inguinal hernia repair, occult inguinal hernias not reported by physical examination are frequently found during surgery. Occult inguinal hernia is an early inguinal hernia, which is easy to be ignored because its clinical symptoms are not obvious. Currently, the best diagnostic method for occult inguinal hernia is laparoscopy, Noninvasive tests such as ultrasound and MRI should be performed in patients with first symptoms. With the increase of age, abdominal wall strength decrease, and the proportion of occult inguinal hernia requiring treatment will also increase, doctors need to choose a reasonable treatment plan according to the actual situation of patients. The key to the diagnosis and treatment of occult inguinal hernia lies in making clear its definition and establishing uniform diagnostic criteria. Through reasonable and accurate preoperative examination combined with laparoscopic techniques and the adjustment of surgical approaches, occultic defects can be found and repaired. Individualized treatment for different populations can avoid future symptoms and reduce additional surgical risks.

Although DNA 5-hydroxymethylcytosine (5hmC) is recognized as an important epige-netic mark in cancer, its precise role in lymph node metastasis remains elusive. In this study, we investigated how 5hmC associates with lymph node metastasis in breast cancer. Accompanying with high expression of TET1 and TET2 proteins, large numbers of genes in the metastasis-positive pri-mary tumors exhibit higher 5hmC levels than those in the metastasis-negative primary tumors. In contrast, the TET protein expression and DNA 5hmC decrease significantly within the metastatic lesions in the lymph nodes compared to those in their matched primary tumors. Through genome-wide analysis of 8 sets of primary tumors, we identified 100 high-confidence metastasis-associated 5hmC signatures, and it is found that increased levels of DNA 5hmC and gene expression of MAP7D1 associate with high risk of lymph node metastasis. Furthermore, we demonstrate that MAP7D1, regulated by TET1, promotes tumor growth and metastasis. In conclusion, the dynamic 5hmC profiles during lymph node metastasis suggest a link between DNA 5hmC and lymph node metastasis. Meanwhile, the role of MAP7D1 in breast cancer progression suggests that the metastasis-associated 5hmC signatures are potential biomarkers to predict the risk for lymph node metastasis, which may serve as diagnostic and therapeutic targets for metastatic breast cancer.

[Abstract] Objective: To investigate the effect of alantolactone (ALT) on proliferation, migration, invasion and apoptosis of human osteosarcoma 143B cells and the underlying mechanism. Methods: Osteosarcoma 143B cells were treated with different concentrations of ALT (0, 4, 6, 8, 10 µmol/L). Then, the cell proliferation ability was detected by crystal violet staining and MTT assay, cell migration was determined by Wound-healing test, cell invasion was analyzed by Transwell assay and cell apoptosis rate was detected by Hoechst33258 staining. The mRNA and protein expressions of E-cadherin, N-cadherin, caspase-3, cleaved caspase-3 (c-caspase-3), poly ADP-ribose polymerase (PARP) and cleaved PARP (c-PARP) in 143B cells were detected by qPCR and Western blotting (WB), respectively. TCF/LEF (T cell lymphocyte factor/lymphoid enhancer factor) transcriptional activity was examined with Luciferase reporter gene assay. The mRNA and protein expressions of β-catenin as well as MMP-7 and c-Myc were detected by qPCR and WB, respectively. Results: ALT inhibited proliferation, migration and invasion of osteosarcoma143B cells and promoted apoptosis(P<0.05or P<0.01). After the treatment with ALT at 8, 10 µmol/L, the mRNA and protein expressions of E-cadherin and PARP, as well as the protein expressions of c-caspase-3 and c-PARP were up-regulated, while the mRNA and protein expressions of N-cadherin were downregulated (P<0.05 or P<0.01);At the sametime, theTCF/LEF transcriptional activity and the mRNA and protein expressions of β-catenin, MMP-7 and c-Myc were significantly down-regulated (P<0.05 or P<0.01). Conclusion:ALT may inhibit the proliferation, migration and invasion and promote cell apoptosis possibly through suppressing Wnt/β-catenin signaling pathway in osteosarcoma 143B cells.
