Objective To identify the independent predictors of programmed death-1 (PD-1) inhibitor-related endocrine adverse events and construct a clinically usable risk prediction model. Methods A total of 302 patients with solid tumors treated with PD-1 inhibitors were retrospectively enrolled. According to the presence or absence of endocrine immune-related adverse events (irAEs), the patients were divided into case group and control group. The clinical and laboratory indexes were compared between the two groups. Multivariable logistic regression was used to confirm independent predictors of endocrine irAEs. The nomogram was constructed, while the receiver operating characteristic (ROC) curve was used to test the prediction performance of the model. Results The overall incidence of endocrine irAEs was 21.9% (66/302), and the incidence of hypothyroidism was 19.5% (59/302). The age, PD-1 inhibitors, free thyroxine, thyroid peroxidase antibody (TPOAb), thyroglobulin, amylase, lymphocyte subset CD3 expression were statistically different between the two groups (P＜0.05). Multivariable logistic regression showed that higher expression of lymphocyte subset CD3 was a protective factor to prevent endocrine irAEs occurrence (P＝0.004), while age＜60 years, higher TPOAb and use of pembrolizumab were independent risk factors of endocrine irAEs (P＜0.05). The nomogram model thus constructed, and when the threshold probability of the model exceeded 0.1, its net benefit was higher. ROC curve showed that the AUC of the model to predict endocrine irAEs was 0.760. The prediction result of the model was highly consistent with the actual result. Conclusions The age, type of PD-1 inhibitor, baseline TPOAb level, and baseline CD3 expression can independently predict endocrine irAEs occurrence or not. The nomogram model based on this model has good predictive efficiency, which can provide reference for early identification of high-risk patients and immunotherapy management.

Objective:To investigate the value of soluble interleukin-6 (IL-6) receptor (sIL-6R) level in predicting ultrafiltration insufficiency in peritoneal dialysis (PD) patients.Methods:It was a prospective cohort study. The patients who received continuous ambulatory PD and regular follow-up between November 2016 and July 2018 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled. Enzyme-linked immunosorbent assay was used to determine dialysate sIL-6R and its appearance rate (AR) was calculated. Patients were divided into high sIL-6R AR group and low sIL-6R AR group according to median value of sIL-6R AR and prospectively followed up until death, PD cessation, or the end of the study (December 31, 2022). Multiple linear regression was used to analyze the related factors of sIL-6R AR. Kaplan-Meier method and log-rank test were used to compare the survival rate difference of ultrafiltration insufficiency between high sIL-6R AR group and low sIL-6R AR group. Multivariate Cox regression and multivariate competing risk models were used to assess the risk factors associated with occurrence of ultrafiltration insufficiency.Results:A total of 198 PD patients were enrolled, including 115 (58.1%) males, with age of (54.9±13.7) years old and PD duration of 22.5 (6.6, 65.0) months. The sIL-6R AR of the cohort was 2 094.7 (1 672.4, 2 920.9) pg/min. Compared with low sIL-6R AR（<2 094.7 pg/min）group, high sIL-6R AR（>2 094.7 pg/min）group had older age ( t=-3.269, P=0.001), higher body mass index ( t=-3.248, P=0.001), proportion of combined diabetes mellitus ( χ2=8.890, P=0.003), 24 h glucose exposure ( Z=-2.257, P=0.024), 24 h ultrafiltration capacity ( Z=-2.515, P=0.012), 4 h dialysate creatinine to serum creatinine ratio ( t=-2.609, P=0.010), mass transfer area coefficient of creatinine ( Z=-2.308, P=0.021), IL-6 AR ( Z=-3.533, P<0.001) and solute glycoprotein 130 AR ( Z=-8.670, P<0.001), and lower serum albumin ( t=2.595, P=0.010) and residual renal function ( t=2.133, P=0.033). Multiple linear regression analysis showed that body mass index ( β=0.194, P=0.005), serum albumin ( β=-0.215, P=0.002) and dialysate lg[IL-6 AR] ( β=0.197, P=0.011) were independently correlated with sIL-6R AR. By the end of the study, 57 (28.8%) patients developed ultrafiltration insufficiency. Kaplan-Meier analysis showed that high sIL-6R AR group had a significantly inferior ultrafiltration insufficiency-free survival rate than that in low sIL-6R AR group (log-rank χ 2=5.375, P=0.020). Multivariate Cox regression analysis and multivariate competing risk models showed that high dialysate sIL-6R AR (>2 094.7 pg/min) was an independent influencing factor of ultrafiltration insufficiency ( HR=2.286 , 95% CI 1.254-4.165 , P=0.007 ; SHR=2.074, 95% CI 1.124-3.828, P=0.020) in PD patients. Conclusions:Dialysate sIL-6R level was associated with body mass index, serum albumin and dialysate IL-6 level. Dialysate sIL-6R may be a predictive factor of ultrafiltration insufficiency in PD patients.

Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

Objective To investigate the efficacy and safety of transumbilical single-port laparoscopic appendicectomy in acute complicated appendicitis.Methods Retrospective analysis was conducted for the data of 1104 patients with complicated appendicitis who underwent emergency laparoscopic appendectomy at the Department of General Surgery of Aerospace Center Hospital from April 2014 to August 2022;among them,788 patients underwent transumbilical single-port laparoscopic appendectomy(SILA)and 316 cases underwent traditional three-port laparoscopic appendectomy(LA);the operation time,intraoperative blood loss,leukocyte value on the first day after surgery,postoperative exhaust time,hospital stay,postoperative pathology and postoperative complications were statistically analyzed.Results The surgical duration of the single hole laparoscopic appendectomy(SILA)group was(68.26±22.29)minutes,intraoperative blood loss was(15.93±13.10)ml,postoperative exhaust time was(2.29±0.52)days,and white blood cells were(11.12±1.67)× 109/L on the first day after surgery,and the surgical duration of the hree hole laparoscopic appendectomy(LA)groupwas(66.47± 20.40)minutes,intraoperative blood loss was(16.65±12.98)ml,postoperative exhaust time was(2.23±0.58)days,and white blood cells were(11.35±1.54)× 109/L on the first day after surgery,there was no statistically significant difference in the data between each group(P＞0.05).After 1 month of follow-up,no incisional hernia and other complications occurred in the two groups,the cosmetic effect of abdominal incision in SILA group was satisfactory,the hospitalization time of SILA group was(4.60± 1.18)days,which was shorter than that in the traditional LA group(4.93±1.71)days,and the difference was statistically significant(P＜0.05).Conclusion Based on proficiency in traditional LA operations,SILA is safe and viable;in addition to the hidden aesthetic function of scars,it does not prolong the operation time and increase the risk of postoperative complications.

This study explored the correlation between color and chemical components of Chrysanthemi Indici Flos(CIF), aiming at providing a reference for its procurement, evaluation, and breeding. Colorimeter and ultra-performance liquid chromatograph(UPLC) were used to determine the color(lightness-shade chromaticity value L~*, red-green chromaticity value a~*, yellow-blue chromati-city value b~*) and chemical components(cynaroside, linarin, luteolin, apigenin, and chlorogenic acid) of 84 CIF germplasms, respectively. Diversity analysis, correlation analysis, regression analysis, and cluster analysis were performed. The results showed that the color and chemical components of CIF were diversified. Chlorogenic acid was in significantly positive correlation with L~* and b~* and significantly negative correlation with a~*. Cynaroside and grey relational grade γ_i of chemical components were in significantly po-sitive correlation with b~* and L~*, respectively, whereas linarin, luteolin, and apigenin had no significant correlation with L~*, a~*, or b~*. The 84 CIF germplasms were clustered into 4 clades. In addition, germplasms in clade Ⅲ had higher γ_i and total color value(E~*_(ab)) than those in other clades, with the best quality and color, and a germplasm with the highest quality, bright yellow color, and highest content of linarin was screened out in this clade. Thus, CIF with bright yellow color had high content of cymaroside and chlorogenic acid and thereby high quality. In summary, the color can be used to quickly predict the quality of CIF. Our results provided data for the evaluation of CIF quality by color and a reference for its procurement and breeding.

Objective:To investigate the clinical feasibility of three-dimensional contrast-enhanced ultrasound (3D-CEUS) in the quantitative assessment of blood perfusion of hepatocellular carcinoma (HCC).Methods:Between January 2020 and August 2021, 36 HCC patients (39 lesions in total) confirmed by pathology and clinical diagnosis without any treatment from Zhongshan Hospital, Fudan University were enrolled and underwent both 2D-CEUS and 3D-CEUS examinations. Each examination last for 150 s and all images were recorded, and then the data were analyzed. A region of interest was manually drawn along the margin of the whole tumor and then the time-intensity curve (TIC) generated. The following perfusion parameters were extracted: peak intensity (PI), peak time (TTP), ascending slope (AS), mean transit time (MTT) and area under the curve (AUC). After calculating the quality of fit (QOF) of the curve, the intraobserver agreement of the 3D-CEUS quantitative parameters obtained by the same doctor between two times were assessed, and the consistency of the 3D-CEUS and 2D-CEUS quantitative parameters was evaluated when QOF>75%. The differences of the quantitative parameters between different groups (divided by depth of 8 cm and necrosis rate of 50%, respectively) in 3D-CEUS were compared.Results:There were 38 lesions (97.4%, 38/39) with QOF>75% in 3D-CEUS. The intraobserver agreement was excellent, the intraclass correlation efficient(ICC) values was 0.85-0.99. The consistency of the time quantitative parameters (TTP and MTT) were high (the ICC values of 0.87 and 0.91), and the correlation of intensity quantitative parameters were substantial, the rs values were 0.71, 0.72 and 0.71. The differences in 3D-CEUS quantitative parameters of the two groups of lesions with different depths were statistically significant (all P<0.05); but there were no significant differences in quantitative parameters between the two groups with different necrosis rate (all P>0.05). Conclusions:Quantitative 3D-CEUS is an useful and creditable tool in evaluating the blood perfusion of HCC, especially when the depth of lesion was less than 8 cm.

Dental caries are common diseases in children and often affect their growth and development. In order to understand the dental caries status of preschool children in Qingdao, a total of 1 690 children aged 3-6 years were screened from 13 kindergartens in two districts of Qingdao. The oral health examination was conducted according to the WHO standard, including the decayed-missing-filled index and pigmentation status. The prevalence of caries, the mean decayed, missing and filled tooth (dmft) and the mean dmfs were calculated. The results showed that the prevalence of deciduous teeth caries of children was 65.3% (n=1 103) with the mean dmft and dmfs about 3.2 and 5.4. There was a statistically significant difference in the prevalence of deciduous teeth caries among different age groups (P<0.001). There was a statistically significant difference between the prevalence of deciduous teeth caries with and without pigmentation (P<0.001). The prevalence of caries in preschool children in Qingdao is high and more attention should be paid to their dental caries.
