To investigate the effect of Xuebijing injection (XBJ) on cGAS/STING pathway in alleviating sepsis-induced acute lung injury (ALI), the mouse sepsis-induced ALI model was established by cecal ligation and puncture (CLP), and the cell inflammation model was constructed by LPS stimulating RAW264.7 cells. The effects of XBJ on lung tissue injury and cGAS/STING pathway-related protein expression in septic mice were investigated by HE staining, ELISA, and Western blot. The results showed that XBJ intervention could alleviate lung tissue injury, reduce serum IL-6, TNF-α, IFN-β, IL-1-β levels, and the expression of cGAS, STING, p-TBK1, and p-IRF3 proteins in lung tissue in vivo, and reduce the mRNA level of related inflammatory factors in RAW264.7 cells and the expression of cGAS/STING pathway proteins in vitro. The results showed that XBJ could play a role in the prevention and treatment of sepsis-induced ALI by inhibiting the inflammatory response via inhibition of the activation of cGAS/STING pathway. This study provides a new molecular mechanism for the clinical prevention and treatment of sepsis-induced acute lung injury with XBJ.

Bisphenols are widely used in the manufacture of polycarbonates and plastics. With the restriction and banning of bisphenol A (BPA), a typical representative of bisphenols, bisphenol S (BPS) has been widely used in the manufacture of various polymers as the main alternative to BPA. Humans are exposed to BPS through a variety of routes, and BPS is detected in food, environment, and human blood and excreta. Concerns about the safety of BPS have become an important issue, especially for pregnant women and fetuses. The results of several studies support that prenatal exposure to BPS have multiple adverse effects on the offspring. In particular, prenatal BPS exposure may affect maternal and offspring metabolic homeostasis and increase the risk of abnormal lipid metabolism in the offspring. This paper summarized the results of studies on BPS exposure and abnormal lipid metabolism. In addition, this review explored potential mechanisms of BPS, including its possible influence on lipid metabolism through interference with hormone receptors, activation of the nuclear receptor peroxisome proliferator-activated receptor γ (PPARγ), induction of oxidative stress and inflammatory states, and epigenetic effects. These findings emphasized the importance of more in-depth research on BPS and its potential effects to better understand its impact on human health and to provide a basis for developing appropriate public health measures to reduce the risk of BPS exposure.

Objective:To retrospectively analyze the independent risk factors of complicated appendicitis(CA)in children under five years old and establish a clinical prediction model, and to evaluate the clinical application of this model.Methods:A retrospective analysis was performed on children under five years old who underwent appendectomy at Children′s Hospital of Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021.The children were divided into CA group and uncomplicated appendicitis group according to whether there was sign of perforation or gangrene in appendiceal tissue after operation.The differences in clinical features and preoperative laboratory test results between two groups were compared.The independent risk factors of CA were identified and a clinical prediction model was established.The clinical prediction model was verified by receiver operating characteristic curve.Results:A total of 140 children were enrolled in this study, including 84 cases in the CA group and 56 cases in uncomplicated appendicitis group.Univariate and binary Logistic regression analysis showed that the duration of symptoms>23.5 h( OR=6.650, 95% CI 2.469-17.912, P<0.05), abdominal muscle tension( OR=3.082, 95% CI 1.190-7.979, P<0.05) and C-reactive protein>41 mg/L ( OR=3.287, 95% CI 1.274-8.480, P<0.05) were independent risk factors for CA( P<0.05). The clinical prediction model of CA was constructed by the above mentioned three independent risk factors.The area under the receiver operating characteristic curve of the clinical prediction model was 0.881(95% CI 0.825-0.936), the sensitivity was 77.4%, the specificity was 87.5%, the positive predictive value was 91.3% and the negative predictive value was 70.0%. Conclusion:Acute appendicitis in children under five years old is more likely to progress to CA if the duration of symptoms>23.5 h, the level of C-reactive protein is increased, and the abdominal muscle tension is accompanied.The clinical prediction model of CA constructed by common clinical information in pediatric clinics has good prediction efficiency, which provides a simple and feasible reference method for clinicians to distinguish CA from uncomplicated appendicitis.

Objective:To establish a decision tree model of pediatric complicated appendicitis (CA) based on Pediatric Appendicitis Score (PAS) combined with inflammatory indicators, and to evaluate its clinical application efficacy in pediatrics.Methods:The clinical data of 544 children diagnosed with appendicitis in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021 was retrospectively analyzed. According to postoperative pathology, the children were divided into uncomplicated appendicitis group and CA group. The independent risk factors of CA were screened by univariate and multivariate logistic regression analysis, and these parameters were included to establish the decision tree model. The accuracy of the decision tree model was verified by receiver operating characteristic (ROC) curve.Results:Binary logistic regression analysis indicated that the PAS, C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) were identified as independent risk factors for complicated appendicitis in children (all P<0.05). PAS, CRP and NLR were included as covariables to construct the decision tree model and binary logistic regression model for predicting CA. The decision tree demonstrated an overall accuracy of 79.2% with a sensitivity of 86.7% and specificity of 71.9%, and achieved an area under curve (AUC) of 0.821(95% CI: 0.786-0.857). The binary logistic regression model had a sensitivity of 79.6% and specificity of 69.1%, with an overall accuracy of 75.1% and achieved an AUC of 0.808(95% CI: 0.770-0.845). Conclusions:The decision tree model based on PAS score combined with CRP, NLR is a simple, intuitive and effective tool , which can provide pediatric emergency physicians a reliable basis for diagnosis of pediatric CA.

Objective:To provide anatomic data of the coracoclavicular (CC) ligament attachment regions in Chinese population for anatomic reconstruction of CC ligament to treat acromioclavicular dislocation.Methods:The CC ligaments were first dissected layer by layer out of the bilateral acromioclavicular joint specimens taken from 87 adult cadavers. The CC width and thickness on the attachments of the clavicle and the coracoid process were measured by an electronic digital caliper. The conoid ligament and trapezoid ligament were mapped on the surface of the clavicle and the coracoid process by transecting the ligaments close to their insertions. The distances from the ligament footprint center to the lateral, anterior and posterior margins of the clavicle were measured. The distances from the ligament footprint center to the tip, medial and lateral margin borders of the coracoid process were measured.Results:The distances from the lateral edge of the clavicle to the footprint centers of the conoid and trapezoid ligaments were (35.7 ± 3.4) mm and (21.8 ± 2.7) mm, and the ratio of the distance divided by the clavicular length was 25.5% ± 0.9% and 15.6% ± 1.1%, respectively. The distances from the tip of coracoid to the footprint centers of the conoid and trapezoid ligaments were (35.1 ± 3.2) mm and (29.7 ± 2.9) mm, and the ratio of the distances divided by the coracoidal length was 86.7% ± 1.9% and 73.3% ± 2.1%, respectively.Conclusion:Although the absolute position of the CC ligament attaching to the clavicle and the coracoid process varies greatly among Chinese individuals, the ratio of its relative position to the length and width of the clavicle and the coracoid process is a relatively stable set of data.

Objective : To investigate the effects of gestational diabetes mellitus (GDM) on birth outcome and umbilical artery (UA) blood flow parameters in the third trimester, and to analyze the role of UA blood flow parameters in GDM and birth outcome. Methods : Based on the birth cohort from Wuhu , Anhui , China , 189 pregnant women with GDM were collected as the case group. The non⁃GDM pregnant women were matched 1 ∶ 1 according to age and pre⁃pregnancy body mass index , and 189 normal pregnant women were selected as the control group. Pregnant women with GDM were divided into poorly controlled group and well controlled group according to fasting blood glucose in the third trimester. The UA blood flow parameters and fetal birth outcomes in the third trimester were tracked. Results : Compared with the control group , UA parameters in poorly controlled and well controlled groups significantly increased (F = 6. 63 , P < 0. 05 ; F = 4. 43 , P < 0. 05 ; F = 5. 57 , P < 0. 05) . Poor glycemic control of GDM was associated with increased birth weight and risk of larger than gestational age. The multi⁃factor linear regression model showed that the Z score of the peak systolic velocity/end diastolic velocity (S/D) in the poorly controlled group was negatively correlated with birth weight (β = - 209. 78 , 95% CI: - 301. 48 - 118. 07) . S/D index Z score mediated the relationship between poor blood glucose control and birth weight. The intermediate effect value was - 58. 41 (95% CI: - 106. 40 ~ - 19. 65) , accounting for 25. 98% of the total effect. Conclusion Poor glycemic control in GDM is a risk factor for fetal weight gain , and UA function plays a partial mediating role in influencing neonatal birth weight. GDM pregnant women should strictly control blood glucose level to better protect maternal and infant health.

Objective : To investigate the correlation between nocturnal sleep duration combined with snoring in the first trimester of pregnancyand small for gestational age(SGA) ，large for gestational age(LGA) ． Methods : Multi- variate Logistic regression model was used to analyze the association between nocturnal sleep duration ，snoring， their combined effects and SGA，LGA. Results : Compared to nocturnal sleep duration 7 to 9 h in the first trimester of pregnancy，sleep duration＜7 h was positively correlated with SGA in male newborn( OR = 4. 22，95% CI : 1. 69 - 10. 52) ; After stratified by snoring，the sleep duration of snoring women＜7 h was positively correlated with SGA ( OR = 5. 68，95% CI : 1. 02－31. 51) ，and the sleep duration of non-snoring women＜7 h was positively correlated with LGA ( OR = 2. 10，95% CI : 1. 16 －3. 81) ． Conclusion Sleep duration＜7 h in the first trimester of preg- nancy is a risk factor for SGA and LGA，and snoring may enhance the association between sleep duration＜7 h in the first trimester of pregnancy and SGA．Pregnant women should keep adequate nocturnal sleep duration to reduce the risk of abnormal neonatal weight.

Objective:To study the predictive value of hour-specific total serum bilirubin(TSB) nomogram combined with clinical risk factors in the risk of hyperbilirubinemia.Method:Perinatal clinical data of newborns born in Shanghai Pudong New Area Health Care Hospital for Women and Children, Shanghai Pudong New Area People's Hospital and Shanghai Pudong Hospital from August 2017 to July 2018 were collected in this prospective study. Transcutaneous bilirubin (TcB) was monitored before discharge from hospital. Enrolled neonates were followed up for 28 days. The patients were assigned to neonatal hyperbilirubinemia group (NHB) and non-hyperbilirubinemia group (Non-HB) according to the occurrence of hyperbilirubinemia. The predictive value of models for the risk of hyperbilirubinemia was evaluated by receiver operating characteristic (ROC) curves and Logistic regression analysis.Result:A total of 8 664 newborns were included in this study, with 1 196 cases of hyperbilirubinemia, with an incidence of 13.8%. Logistic regression analysis showed that maternal blood type O, premature rupture of membranes, male gender, gestational age 35~37 weeks, subcutaneous ecchymosis/cranial edema, and breastfeeding were independent risk factors for NHB ( P<0.05). The area under receiver operative characteristic curve (ROC) of predischarge bilirubin risk zone only was 0.874(95% CI 0.861~0.885, P<0.05)and for all independent risk factors was 0.664 (95% CI 0.647~0.680, P<0.05). The area under ROC curve was 0.891 (95% CI 0.880~0.902, P<0.05) by combining predischarge bilirubin risk zone with clinical risk factors. Conclusion:Predischarge bilirubin risk zone combined with clinical risk factors can reasonably predict neonatal hyperbilirubinemia well.

Objective: To simplify the psychological domain of Multidimensional Sub-health Questionnaire of Adolescents (MSQA),which includes 39 items and develop the Brief Instrument On Psychological Health of Youths(BIOPHY), as well as to evaluate the predictive validity of the BIOPHY. Methods: A total of 14 221 students were recruited from Shenyang,Xinxiang,Guangzhou,and Chongqing by using multistage stratified cluster random sampling to participate in the study. A combination of item analysis,factor analysis and reliability evaluation were used to screen items and evaluate the questionnaire. Meantime, data from 14 500 adolescents from Shenzhen,Nanchang,Zhengzhou and Guiyang in 2017 were used to develop a cut-off point and to evaluate its predictive validity. Results: On the basis of item analysis,BIOPHY consisted of 15 items. Variance cumulative contribution rate was 57.39%; internal consistency test showed that the total questionnaire Cronbach α coefficient was 0.928. The split-half coefficient of the total questionnaire was 0.909. The 90th percentile of total scores was used as the cutoff point of BIOPHY. The results of multivariate logistic regression analysis showed that students with psychological health symptoms were at significantly higher risk of depressive symptoms (OR=10.53,95%CI=9.28-11.94),suicide ideations (OR=5.77,95%CI=5.15-6.46),suicide plans (OR=6.09,95%CI=5.39-6.89) and suicide attempts (OR=4.80,95%CI=4.04-5.69) than normal counterparts. Conclusion The BIOPHY is consistent with the evaluation standard of psychometrics. The predictive validity of BIOPHY is good and could be used in the future researches focusing on adolescent mental health.

Objective:To conduct an MRI observation on the incidences of ligamentous injuries and fracture morphology in Schatzker type Ⅳ tibial plateau fracture (TPF) and investigate their influence on knee stability.Methods:A retrospective analysis was conducted of the 30 patients with Schatzker type Ⅳ TPF who had undergone surgery at Department of Orthopaedic Trauma, Jiangsu Provincial People's Hospital from January 2010 to December 2019 and whose preoperative X-ray, CT and MRI were available. They were 18 males and 12 females, aged from 22 to 75 years (mean, 45.4 years). They were divided into a dislocation-free group and a dislocation group according to the absence or presence of knee dislocation on their anteroposterior X-ray films. The fracture morphology was assessed on CT according to the modified three-column classification. The incidences of ligamentous injuries [involving anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), posterolateral complex (PLC) and anterolateral ligament (ALL)] were investigated on MRI. The 2 groups were compared in fracture morphology and incidences of ligamentous injuries. Multiple linear regression (MLR) analysis was used to identify the main factor contributing to preoperative knee dislocation.Results:The dislocation group had 12 patients and the dislocation-free group 18. The fracture involving medial+posteromedial+posterolateral columns was found in 66.7% of the patients (20 cases), and accounted for 83.3% (10 cases) in the dislocation group. The incidence was 96.7% (29 cases) for ACL injury, 43.3% (13 cases) for PCL injury, 70.0% (21 cases) for MCL injury, 90% (27 cases) for PLC injury, 73.3% (22 cases) for ALL injury and 90% (27 cases) for the multiple-ligament disruption. There was a significant difference in the posterolateral column injury between the dislocation-free group [55.6% (10/18)] and the dislocation group [91.7% (11/12)] ( P < 0.05), but there were no significant differences between the 2 group in the injury to any other single ligament or multiple ligaments ( P>0.05). The MLR analysis confirmed that the posterolateral column injury was a risk factor for coronary plane dislocation in Schatzker type Ⅳ TPF( P<0.05). Conclusions:In Schatzker type Ⅳ TPF, the incidences of ligamentous injuries are very high but the fracture of posterolateral column may be the main cause for preoperative knee dislocation in some patients.
