Objective To investigate the causal relationship between circulating white blood cells(WBC)and juvenile idiopathic arthritis(JIA)using a two-sample Mendelian randomization(MR)analysis,and to provide a reference for the treatment strategy of JIA.Methods Relevant data of WBC and JIA were extracted from the public data of genome-wide association studies.Then,bidirectional MR analysis was conducted using the inverse variance weighted method(IVW),MR-Egger regression method,mixed contamination method,and Bayesian weighted Mendelian randomization.A series of sensitivity analyses were used to verify the robustness of the results.Results After MR analysis,false discovery rate(FDR)correction and sensitivity verification,calculations using IVW as the main method showed that neutrophils could reduce the risk of JIA(OR=0.752,95%CI:0.622,0.908,P=0.003,PFDR=0.003),and that JIA could lead to increased monocyte counts(bete=0.015,95%CI:0.007,0.022,P=1.90E-04,PFDR=1.14E-03).Conclusion A bidirectional causal association is identified between WBC and the risk of JIA occurrence.

Complex post-traumatic stress disorder (CPTSD) is a newly introduced diagnosis in the International Classification of Diseases, 11th Revision (ICD-11), characterized by emotional dysregulation, interpersonal difficulties, and a negative self-concept. CPTSD typically occurs in individuals exposed to prolonged traumatic environments, such as physical abuse, emotional abuse, sexual assault, school bullying, imprisonment, or torture, and exerts a profound impact on social functioning. Current evidence suggests that the development of CPTSD is influenced by psychological, family, social, and cultural factors. The International Trauma Questionnaire (ITQ) has emerged as the core assessment tool, and staged treatment remains the predominant therapeutic principle. Nevertheless, research on CPTSD in China remains limited. This review addresses the conceptual development, associated factors, neurobiological mechanism, clinical manifestations, assessment instruments, diagnostic strategies, treatment approaches, and rehabilitation measures of CPTSD, aiming to provide a reference for future clinical practice and research.

Objective Based on the intervention map to develop a comprehensive nutrition education program for pancreaticoduodenectomy patients and to explore the effect of its clinical application,aiming at providing references for clinical nursing practice.Methods A convenience sampling method was used to select 76 patients who were to undergo pancreaticoduodenectomy in the department of hepatobiliary and pancreatic surgery of a tertiary hospital in Anhui Province as the study subjects.The 38 patients admitted from October 2021 to September 2022 were in a control group,and the 38 patients admitted from October 2022 to July 2023 were in an experimental group.The experimental group received the comprehensive nutritional education programme constructed in this study,and the control group used conventional nutrition health education measures,and the length of intervention for both groups was from pre-hospitalization to discharge for 6 months.Nutrition-related indicators,postoperative complications,hospitalisation time,hospitalisation costs and satisfaction were compared between the 2 groups.Results A total of 64 patients completed this study,with 33 in the experimental group and 31 in the control group.Repeated measurement analysis of variance showed that the interaction effects of BMI,total serum protein and serum preprotein were statistically significant(P＜0.05).The incidence of complications,hospitalization days and hospitalization costs of the experimental group were lower than those of the control group(P＜0.05).The scores of nutrition education-related satisfaction in the experimental group were higher than those in the control group(P＜0.001).Conclusion A comprehensive nutritional education program based on intervention map can improve the nutritional status of pancreaticoduodenectomy patients to a certain extent,reduce the occurrence of complications,and promote patients'recovery.

Objective:To explore the clinical characteristics of adrenal lesions in unilateral primary aldosteronism.Methods:This is a prospective study. Consecutive patients diagnosed with unilateral primary aldosteronism at the First Affiliated Hospital of Chongqing Medical University from December 2023 to November 2024 were included. Inclusion criteria：① Age is 18 to 80 years old；② The laboratory test indicators are in line with the diagnosis of primary aldosteronism；③ The auxiliary examination proved that only one side was involved；④ Patient undergo unilateral total adrenalectomy. The exclusion criteria are as follows：① Complete biochemical remission was not achieved during the 1-6 month follow-up after the surgery；② Postoperative loss to follow-up；③ No surgical specimens were received or the surgical specimens were incomplete，making continuous sectioning impossible. Patients meeting the inclusion criteria were recruited，and their clinical and biochemical data were recorded. The number of adrenal nodules visible on CT scans and the number of macroscopically visible nodules in the postoperative adrenal gross specimens were documented. Hematoxylin-eosin（HE）staining and aldosterone synthase CYP11B2 immunohistochemical staining were performed on the adrenal tissues after the operation. The number of nodules visible under the light microscope and the number of CYP11B2-positive nodules were recorded.Results:A total of 114 cases were included in this study. The age of the patients was（49.86 ± 9.80）years，the body mass index was（25.49 ± 3.40）kg/m2，the preoperative aldosterone level was 352（2012，556）pg/ml，and the direct renin concentration was 1.63（0.50，4.56）μIU/ml. The aldosterone/renin ratio was 224.9（57.1，641.6）（aldosterone concentration unit was pg/ml，renin concentration unit was μIU/ml），the minimum blood potassium concentration was 2.87（2.50，3.40）mmol/L，and the systolic blood pressure was（144.5 ± 19.5）mmHg. Among the 114 patients，105 had adrenal nodules detected by preoperative CT，of whom 2（1.75%）had multiple nodules. Postoperative gross adrenal specimen evaluation and CYP11B2 immunohistochemical staining revealed that 90 out of 114 cases were solitary nodules，2 cases had no nodules，and 22 cases（19.30%）had multiple nodules detected（17 cases had 2 nodules and 5 cases had 3 nodules）. Among them，12 cases（10.53%）presented as grossly visible multinodular lesions，while 10 cases（8.77%）appeared as solitary nodules macroscopically but demonstrated multinodular patterns on immunohistochemical staining. CYP11B2 staining showed that among the 22 patients with multiple nodules，13 had multiple CYP11B2-positive nodules，while the remaining had only one positive nodule. Among the 22 patients with multiple nodules，preoperative CT showed single nodules in 19 cases，hyperplasia in 1 case，and multiple nodules in 2 cases（9.09%）. Among the 12 patients with grossly visible multinodular lesions，preoperative CT showed single nodules in 9 cases，hyperplasia in 1 case，and multiple nodules in 2 cases（16.67%）.Conclusions:Multiple adrenal nodules associated with unilateral primary aldosteronism are relatively common，and are often not detected by preoperative CT examination. Partial adrenalectomy based solely on CT-visible nodules may fail to achieve complete remission of primary aldosteronism. This study provides evidence supporting total adrenalectomy as the preferred surgical approach for unilateral primary aldosteronism.

Objective:To summarize the ultrasonographic characteristics, genetic etiology, and perinatal prognosis of fetuses with absence of ductus venosus (ADV).Methods:A retrospective study enrolled 84 singleton pregnancies that underwent prenatal ultrasound examination and were diagnosed with fetal ADV at the First Affiliated Hospital of Zhengzhou University from June 2017 to July 2022. Based on prenatal ultrasonographic findings, the cases were divided into isolated ADV group ( n=37), ADV with ultrasound soft markers group ( n=9), and ADV with definite ultrasound abnormalities group ( n=38). According to the gestational age at the initial diagnosis of ADV, they were categorized into early pregnancy group (11-13 weeks of 6 days) with 17 cases, mid-pregnancy group (14-27 weeks of 6 days) with 45 cases, and late pregnancy group (≥28 weeks) with 22 cases. Depending on the direction of blood flow in the intra-abdominal segment of the umbilical vein, they were classified into umbilical vein directly entering the portal sinus group ( n=75), intrahepatic umbilical vein abnormal shunt group ( n=4), and extrahepatic umbilical vein shunt group ( n=5). The clinical characteristics of each group were summarized, and compared using the Chi-square, trend Chi-square tests, Fisher's exact test and Bonferroni correction test. Results:The common ultrasonographic abnormalities in the 84 cases of ADV fetuses were cardiac anomalies (27.4%, 23/84), cystic hygroma (10.7%, 9/84), fetal hydrops (9.5%, 8/84), and body cavity effusion (8.3%, 7/84). The proportions of fetuses with ADV and definite ultrasound abnormalities detected in the early, mid, and late pregnancy were 16/17, 44.4% (20/45), and 9.1% (2/22), respectively, with a higher proportion of definite ultrasound abnormalities associated with earlier detection of ADV ( χ 2trend=27.25, P<0.001). Among them, 21 cases underwent chromosomal karyotyping and/or chromosomal copy number variation sequencing or expanded non-invasive prenatal testing, with five abnormalities detected, including 45,X, trisomy 13, trisomy 22 mosaicism, trisomy 7 mosaicism, and a 14 Mb duplication at 22q12.3q13.33. The neonatal survival (28 days after birth) rates with ADV detected in the early, mid, and late pregnancy gradually increased, at 1/17, 43.9% (18/41), and 90.5% (19/21), respectively ( χ 2trend=27.04, P<0.001). The neonatal survival rates of the isolated ADV group and the group with ultrasound soft markers were higher than that of the group with definite ultrasound abnormalities [93.9% (31/33) and 6/9 vs. 2.7% (1/37), Bonferroni corrected, both P<0.001]. The neonatal survival rates of the umbilical vein directly entering the portal sinus group, intrahepatic umbilical vein abnormal shunt group, and extrahepatic umbilical vein shunt group were 50.0% (35/70), 0/4, and 1/5, respectively, with no statistically significant difference (Fisher's exact test, P=0.105). Conclusions:The earlier the detection of fetal ADV, the more likely it is to be associated with definite ultrasound abnormalities and have lower neonatal survival rates. This highlights the importance of ultrasonographic examination of the fetal ductus venosus. Once ADV is detected, attention should be paid to other potential ultrasound abnormalities, and genetic testing should be completed.

Objective To investigate the expression level and clinical application value of serum resistin in patients with systemic lu-pus erythematosus(SLE).Methods Forty-five SLE patients visited Nanjing Drum Tower Hospital,Clinical College of Nanjing Uni-versity of Chinese Medicine from January to August 2023 were enrolled in the study.The patients were scored and grouped according to the SLE disease activity index(SLEDAI),with SLEDAI＜9 score in the inactive group(n=32)and SLEDAI≥9 score in the active group(n=13).Thirty-four healthy individuals who underwent physical examination in our hospital were recruited as healthy controls.The clinical data and laboratory related indicators such as urine protein and serum complement C3 levels were collected from SLE pa-tients and healthy controls.Serum resistin levels were detected by enzyme-linked immunosorbent assay(ELISA).The clinical screening value of serum resistin for SLE was evaluated with the receiver operating characteristic(ROC)curve.The correlations of serum resistin levels with different laboratory indicators were determined by Pearson correlation analysis.Results The serum resistin levels in SLE patients([7.64±0.64]ng/mL)were significantly higher than that in healthy controls([2.56±0.43]ng/mL),and the difference was statistically significant(t=6.195,P＜0.01).The serum resistin levels in active SLE patients([10.10±1.45]ng/mL)were significant-ly higher than that in inactive SLE patients([6.64±0.60]ng/mL),and the difference was statistically significant(t=2.632,P＜0.05).The area under the ROC curve(AUCROC)of serum resistin for screening SLE was 0.897.When the cut-off value was 5.893 ng/mL,the sensitivity was 86.67%and the specificity was 82.35%.The serum resistin level in SLE patients was positively correlated with urine protein(r=0.692,P＜0.01),while negatively correlated with serum complement C3(r=-0.354,P＜0.05).Conclusion The expression levels of serum resistin in SLE patients are significantly increased and positively correlated with SLE disease activity and urine protein.Serum resistin may become a novel biomarker for the diagnosis and therapeutic effect assessment of SLE.
