Objective To investigate the correlation between the concentration of air pollutants (PM₁₀, SO₂, NO₂) and the number of outpatient and emergency visits for pediatric respiratory diseases in a general hospital in Shanghai. Methods Data including pediatric respiratory disease outpatient and emergency visits in a hospital in Pudong New Area of Shanghai from May 1, 2013 to March 20, 2022 were collected. Daily concentration of air pollutants including PM₁₀, SO₂ and NO₂ and meteorological data in Pudong New Area during the same period were collected. A case-crossover study with distributed lag non-linear model was conducted to explore the correlation between air pollutants (PM₁₀, SO₂, NO₂) and the number of outpatient and emergency visits for pediatric respiratory diseases. Results The concentrations of PM₁₀, SO₂ and NO₂ were positively with the number of outpatient and emergency visits for pediatric respiratory diseases. The strongest cumulative effect was observed on six days lag (Lag0-5) for PM₁₀. For a 10 μg/m³ increase of the concentrations of PM₁₀, the corresponding increase of cumulative pediatric respiratory disease outpatients was 1.10% (95%CI:0.97%, 1.23%) in Lag0-5. The strongest cumulative effect was observed on eight days lag (Lag0-7) for SO₂ and NO₂. For a 10 μg /m³ increase of the concentrations of SO₂ and NO₂, the corresponding increase of cumulative pediatric respiratory disease outpatients was 5.64% (95%CI:5.16%, 6.13%) and 5.41% (95%CI:5.15%, 5.66%) in Lag 0-7, respectively. The association of PM₁₀ and SO₂ with the number of pediatric respiratory disease visits in males was significantly stronger than that in females. The impact of PM₁₀ on the number of pediatric respiratory disease visits in children aged 0-6 was higher than that in children aged 7-14, while the impact of SO₂ and NO₂ on the number of pediatric respiratory disease visits in children aged 7-14 was higher than that in children aged 0-6. Conclusion The concentration of ambient PM₁₀, SO₂, and NO₂ is positively correlated with outpatient and emergency visits for pediatric respiratory diseases, with obvious lag and cumulative effect. Boys and children aged 0-6 are more susceptible to the hazard of air pollution.

Objective:To explore the genetic characteristics of a child with 18q terminal deletion syndrome.Methods:Clinical data of a child presented at the Lianyungang Maternal and Child Health Care Hospital on July 20, 2023 was collected. Peripheral blood sample from the child was subjected to G-banded chromosomal karyotyping and chromosomal microarray analysis (CMA). Relevant literature was searched from CNKI, WanFang and PubMed databases over the past decade (from November 1, 2013 to November 1, 2023) using keywords including "18q-syndrome", "18q deletion syndrome" and "18q terminal deletion". This study was approved by Medical Ethics Committee of the Lianyungang Maternal and Child Health Care Hospital (Ethics No. LYG-MER2021017).Results:The child, a 4-year-and-6-month-old female, had manifested short stature, intellectual disability, distinctive facial features, aortic regurgitation, auditory canal atresia, and white matter lesions. She was found to have a karyotype of 46, XX, del(18)(q21), whilst the result of CMA was arr[GRCh37]18q21.33q23(60065821_77317445)×1. Both of her parents were found to have a normal karyotype. Literature review has retrieved 7 reports which involved 11 cases with a terminal 18q23 deletion. The phenotypes of cardiac abnormalities have been diverse, with pulmonary stenosis, atrial septal defect and ventricular septal defect being most common.Conclusion:The 18q terminal deletion probably underlay the multiple congenital anomalies and mental retardation in this child.

Sarcopenia and physical deconditioning are common complications in patients with liver cancer,which are frequently caused by insufficient physical activity and poor nutritional status,resulting in physical frailty and a significant impact on the patient's physical fitness.Notably,sarcopenia,frailty,and poor cardiopulmonary endurance have all been linked to higher mortality rates among patients with liver cancer.Exercise intervention significantly improves various health parameters in liver cancer patients,including metabolic syndrome,muscle wasting,cardiorespiratory endurance,health-related quality of life,and reduction in hepatic venous pressure gradient.However,the link between physical exercise and liver cancer is commonly overlooked.In this article,we will examine the impact of exercise on liver cancer and present the most recent evidence on the best types of exercise for various stages of liver cancer.This article also summarizes and discusses the molecular mechanisms that control metabolism and systemic immune function in tumors.In brief,physical exercise should be considered an important intervention in the prevention and treatment of liver cancer and its complications.

Objective:To study the effect of diabetes mellitus (DM) on sepsis in patients with pyogenic liver abscess (PLA).Methods:The clinical data of 116 patients with PLA treated in the Affiliated Hospital of Jiangnan University from January 2021 to May 2022 were retrospectively analyzed, including 64 males and 52 females, aged (62.3±12.6) years old. Patients were divided into DM group ( n=56) and non-DM group ( n=60), which were also divided into the sepsis group ( n=29) and the non-sepsis group ( n=87). The clinical features were compared among the groups, the risk factors of PLA complicated with sepsis were analyzed by multivariate logistic regression. Mediation model was used to analyze how DM affects the development of sepsis. Results:Compared with the non-DM group, patients in DM group had higher incidences of hypertension and acute physiology and chronic health evaluation II, a higher proportion of blood neutrophil count, a higher serum levels of triglyceride, urea nitrogen, fasting blood glucose and glycated hemoglobin at admission. The DM group also higher incidences of hypoproteinemia, pleural effusion, and sepsis, with longer hospital stay and higher hospitalization cost (all P<0.05). The levels of hemoglobin, albumin and hematocrit were lower in DM group (all P<0.05). Multivariate logistic regression analysis showed that comorbidity of DM ( OR=3.431, 95% CI: 1.245-9.455) and abscess with a larger diameter ( OR=1.664, 95% CI: 1.258-2.220) were associated with a higher risk of developing sepsis (all P<0.05). Mediation model showed that neutrophil count and triglyceride were the mediating variables of sepsis in patients with PLA. Conclusion:Comorbidity of diabetes is an independent risk factor of developing sepsis in patients with pyogenic liver abscess. Diabetes may induce sepsis by affecting the neutrophils and triglyceride.

OBJECTIVE To investigate the effects of β-sitosterol on the function of rheumatoid arthritis （RA） fibroblastic synoviocytes MH7A cells and its mechanism. METHODS Network pharmacology was adopted to screen the targets of β-sitosterol and the targets for the treatment of RA. After the intersection of them， topological analysis was performed to find the most critical target in the treatment of RA. MH7A cells were treated with different concentrations （0， 5， 10， 20， 40 μmol/L） of β-sitosterol， and CCK-8 was used to assay cell viability for screening the optimal concentration of β-sitosterol. MH7A cells were induced by 10 ng/mL TNF-α in vitro and treated with β-sitosterol （the optimum concentration）. CCK-8 and EdU were used to detect the ability of cell proliferation. Scratch experiment and Transwell invasion assay were used to analyze cell migration and invasion. The levels of interleukin-1β （IL-1β） and IL-6 in cell supernatant were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein expressions of peroxisome proliferator-activated receptor α （PPARα） were measured by qRT-PCR and Western blot， respectively. The siRNA targeting PPARα was transfected into MH7A cells， and the effects of β-sitosterol on cell proliferation， migration， invasion， the secretion of inflammatory factors and the expression of PPARα after PPARα knockdown were detected by the above experimental methods. RESULTS PPARα was the most critical target of β-sitosterol in the treatment of RA. The optimal concentration of β-sitosterol was 20 μmol/L. Compared with model group， β-sitosterol decreased the viability of MH7A cells， and the number of proliferating cells also decreased significantly （P＜0.05）； the cell migration rate and the number of cell invasion decreased significantly （P＜0.05）. The levels of IL-1β and IL-6 were also significantly decreased （P＜0.05）， and the mRNA 15 and protein expression levels of PPARα were significantly increased （P＜0.05）. Compared with negative control small interfering RNA group， after PPARα knockdown， the cell viability increased by about 35.6% （P＜0.05）， the number of cell proliferation， the cell migration rate and the number of cell invasion increased significantly （P＜0.05）， and the levels of IL-1β and IL-6 also increased significantly （P＜0.05）. CONCLUSIONS β-sitosterol could effectively inhibit the proliferation， migration， invasion and secretion of inflammatory factors in MH7A cells， the mechanism of which may be associated with activating PPARα pathway.

Objective:To study the logistic regression model and Chi-square automatic interaction detection decision tree model in the prediction of the recurrence of acute pancreatitis (AP).Methods:Clinical data of 364 patients with AP admitted to the Affiliated Hospital of Jiangnan University from June 2021 to June 2022 were retrospectively analyzed, including 219 males and 145 females, aged 53 (19-91) years. The patients were divided into the recurrence group ( n=63), those who experienced a second or more episodes of AP, and the initial group ( n=301), those who were diagnosed of AP for the first time. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with recurrence of AP, and the decision tree model was used to analyze those factors. Receiver operating characteristic (ROC) curve were plotted to analyze the predictive performance of the two models. Results:Multivariate logistic regression analysis showed that age ( OR=0.969, 95% CI: 0.949-0.990, P=0.004), body mass index ( OR=1.142, 95% CI: 1.059-1.232, P=0.001), and hyperlipidemia ( OR=3.034, 95% CI: 1.543-5.964, P=0.001) were independent factors influencing the recurrence of AP. The accuracy of the model in predicting recurrence was 83.2% (303/364). The decision tree model showed that hyperlipidemia and body mass index were factors influencing the recurrence of AP, with an accuracy of 82.7% (301/364) in predicting recurrence. The area under the ROC curve was larger in the logistic regression model compared to that in the decision tree model (0.776 vs 0.730, Z=2.02, P=0.043). Conclusion:The logistic regression model and the Chi-square automatic interaction detection decision tree model can help predict the recurrence of AP. It is recommended to combine the two models to better guide clinical practice.

Objective:To investigate the association between metabolic syndrome and the risk of early renal function injury in chronic kidney disease(CKD) in the elderly.Methods:A retrospective cohort was established based on health check-up data of 4 495 elderly residents in Mengzi City, Yunnan Province from January 2016 to December 2018. The medial history, living habits, and related physical examination information were collected. Cox hazard regression model was used to explore the association between metabolic syndrome, along with its components, and the early renal function injury in CKD. Results:The median age of the elderly was 71.00(67.00, 75.00) years, with metabolic syndrome detection rate of 21.98%. Early renal function injury of CKD developed in 1 300(28.92%) subjects during the follow-up. Univariate Cox regression showed that the number of metabolic syndrome components was associated with the risk of early kidney development in CKD. The HRs were 1.23 (95% CI 1.03-1.47, P=0.022) with 1 component, 1.54 (95% CI 1.28-1.84, P<0.001) with 2, and 1.38 (95% CI 1.14-1.67, P<0.001) with 3 or more. Multivariate Cox regression showed that elevated fasting triglycerides( HR=1.20, 95% CI 1.07-1.36, P=0.003) and lower high density lipoprotein-cholesterol(HDL-C; HR=1.25, 95% CI 1.09-1.43, P=0.002) were risk factors for early kidney injury in CKD, while doing some physical activity( HR=0.57, 95% CI 0.33-0.98, P=0.042), or on daily basis( HR=0.57, 95% CI 0.49-0.66, P<0.001) was a protective factor for early kidney injury in CKD. Conclusion:The abnormality of one or more metabolic components can significantly increase the risk of early kidney injury in the elderly with CKD. Elevated triglyceride and decreased HDL-C may be the risk factors.
