OBJECTIVES: To analyze the efficacy and safety of concomitant left atrial appendage clipping during heart valve surgery for valvular heart disease patients with atrial fibrillation. METHODS: Fifty-eight patients who underwent concomitant left atrial appendage clipping during cardiac valve surgery in the Second Affiliated Hospital of Nanchang University from January 2017 to June 2023 were included in the analysis, including 1 case who underwent aortic valve replacement, 49 cases who underwent mitral valve replace-ment (or valvuloplasty)+tricuspid valvuloplasty, and 8 cases who underwent double valve replacement+tricuspid valvuloplasty (3 cases combined with coronary artery bypass grafting). The patients were followed up for 3-36 months [(16.69±6.61) months] after operation, and the changes of cardiac function and the occurrence of serious adverse complications were evaluated. RESULTS: The cardiopulmonary bypass time ranged from 75 to 145 min [(102.50±21.03) min], and the aortic cross-clamp time ranged from 35 to 80 min [(58.02±14.63) min]. The length of postoperative intensive care unit stay was 1 to 5 days [(2.47±0.82) d], and the length of postoperative hospital stay was 7 to 22 days [(10.84±2.69) d]. Cardiac ultrasound indicated complete closure of the left atrial appendage in all cases. During the follow-up, New York Heart Association (NYHA) functional classifications were improved in 54 patients. No left atrial appendage-related bleeding events or other perioperative complications were observed; and no cerebral infarction, limb embolism events, or mortality cases occurred during the follow-up. CONCLUSIONS For valvular heart disease patients with atrial fibrillation, concomitant left atrial appendage clipping during cardiac valve surgery demonstrates efficacy and safety, with no severe adverse events during a medium-term follow-up.

Missed abortion is a specific type of spontaneous abortion that typically occurs in early pregnancy. Common causes include embryonic chromosomal abnormalities, maternal factors, immune dysfunction, changes in the local microenvironment, abnormal folate metabolism, endocrine abnormalities, male factors, and environmental influences. Currently, the incidence of missed abortion is rising, and the causes are complex, significantly affecting the physical and mental health of women. This review summarizes the potential causes of missed abortion and provides a valuable basis for prevention, investigation of causes, and early intervention for at-risk populations.

We report the clinical course from birth to adolescence of a patient carrying a compound heterozygous variation in the ectonucleotide pyrophosphatase/phosphodiesterase family member 1(ENPP1) gene. The patient was diagnosed with generalized arterial calcification of infancy shortly after birth, and subsequently with autosomal recessive hypophosphatemic rickets type 2 at the age of 11 years. Following effective blood pressure control, treatment with neutral phosphate, calcitriol, and vitamin D was initiated. During follow-up, no progression of vascular calcification was observed. Through this case report and a review of relevant literature, we aim to enhance clinicians′ understanding of this rare condition.

Objective:To introduce the cultivation model of the scientific research talent echelon in the university-affiliated specialized hospital, and talent cultivation system of Research-Life-Cycle based on this model, summarize its role in promoting discipline development, and propose future measures, providing references for the talent team building and discipline development of specialized hospitals and departments of general hospitals.Methods:This study examined and assessed the effectiveness of the cultivation and the contribution of talents to the advancement of academic disciplines by quantitatively analyzing and comparing the scientific research output and discipline development of personnel trained through the talent echelon policy before and after its implementation for over a decade, and integrating theories related to talent development.Results:Since the implementation of the cultivation model, 116 research talents had completed the cultivation process, accounting for 18% of the hospital′s overall research personnel, and the academic papers echelon talents published as main authors also accounted 60%, which indicated the majority of echelon talents have become the key talents to discipline development and national strategies. The growth rate of the hospital′s papers had significantly increased before and after the policy implementation, with the data rising from 0.16% to the current 1.01% globally.Conclusions:The scientific research talent echelon system has effectively strengthened the cultivation of medical science and technology innovation talents, promoted the formation of the group effect in the hospital, and provided strong support for the development of disciplines. According to the limitations we analyze to the scientific research talent echelon cultivation model, suggestions, for achieving better results in the cultivation of talent echelons, are proposed that we should continuously follow up on national policies to optimize systems, firmly serve for the central task of discipline development, promote the implementation of the comprehensive evaluation to scientific talents, systematically provide young talents with ″real combat″ opportunities, and continuously pursuit the transition from extensive management to refined and personalized management.

The clinical phenotype heterogeneity of epilepsy patients with ADGRV1 gene mutation is significant, ranging from self limiting febrile seizures to developmental epileptic encephalopathy, even causing sudden epileptic death. A case of infantile epileptic spasms syndrome with a novel heterozygous variant of the ADGRV1 gene c.4100C>A (p.Thr1367Lys) was reported in this article. The site of this variant had not been reported yet, and the clinical manifestations of the child mainly included epileptic spasms (first onset at 4 months old), mild growth and development delay, highly irregular video electroencephalogram, and effective treatment with adrenocorticotropic hormone.

To summarize and analyze the clinical data of one case of kidney transplantation in an HIV-positive child with end-stage renal disease (ESRD) in the Department of Transplantation, the People's Hospital of Guangxi Zhuang Autonomous Region, and to explore the safety and efficacy of kidney transplantation in HIV-positive children with ESRD. This pediatric recipient was found to be HIV-positive at birth and underwent kidney transplantation due to ESRD, with good postoperative recovery. During the 2.5-year follow-up, no rejection or rebound in HIV RNA levels was observed. The function of the transplanted kidney was good, and the quality of life was comparable to that of healthy individuals. It suggests that kidney transplantation in HIV-positive children with ESRD is safe and effective under adequate preoperative preparation and close postoperative follow-up.

Objective:To analyze the relationship between neutrophil-to-lymphocyte ratio(NLR) and the levels of inflammatory factors in peripheral blood and the brain injuries of suppurative meningitis in neonates (NPM) and the value of joint prediction of hydrocephalus.Methods:Ninety-five children with NPM diagnosed and treated in the Affiliated Hospital of Jining Medical College from January 2020 to December 2022 were retrospectively selected, including 31 children with non-cerebral parenchymal injury (group A), accounting for 32.63%(31/95); 36 children with parenchymal injury and no hydrocephalus (group B), accounting for 37.89%(36/95); 28 children with brain parenchymal injury and hydrocephalus (group C), accounting for 29.47%(28/95). The clinical data, peripheral blood levels of NLR, interleukin 6(IL-6), hyper-sensitive C-reactive protein (hs-CRP) and procalcitonin (PCT) were compared among the three groups, and the influencing factors of hydrocephalus were analyzed by Logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the value of changes(△, representing the absolute value of the difference between the corresponding indexes and 3 d after admission) in NLR, hs-CRP, IL-6 and PCT in predicting hydrocephalus in NPM alone and combination.Results:The incidence of respiratory failure and convulsion and the levels of NLR, hs-CRP, IL-6 and PCT in the group C were higher than those in the group B and A: 42.86%(12/28) vs. 13.89%(5/36), 6.45%(2/31); 42.86%(12/28) vs. 16.67%(6/36), 3.23%(1/31); 3.91 ± 0.71 vs. 3.12 ± 0.64, 2.16 ± 0.58; (98.21 ± 10.17) mg/L vs. (86.74 ± 9.30), (75.18 ± 8.42) mg/L; (40.73 ± 7.88) ng/L vs. (31.26 ± 6.45), (25.01 ± 5.19) ng/L; (13.26 ± 2.04) ng/L vs (11.83 ± 1.91), (9.45 ± 1.67) ng/L; the levels of NLR, hs-CRP, IL-6 and PCT in the group B were higher than those in the group A, there were statistical differences ( P<0.05). Logistic regression analysis showed that the levels of peripheral blood NLR and serum hs-CRP, IL-6 and PCT at admission were independent risk factors for hydrocephalus in children with NPM ( P<0.05). The △NLR, △hs-CRP, △IL-6 and △PCT of the children with hydrocephalus were lower than those without hydrocephalus: 0.73 ± 0.24 vs. 1.02 ± 0.31, (42.73 ± 13.08) mg/L vs. (69.56 ± 18.19) mg/L, (13.43 ± 4.22) ng/L vs. (19.86 ± 6.43) ng/L, (4.35 ± 1.34) ng/L vs. (6.58 ± 2.03) ng/L, there were statistical differences ( P<0.05). ROC curve analysis results showed that the AUC of △NLR, △hs-CRP, △IL-6 and △PCT combined to predict hydrocephalus in children with NPM was 0.903, which was greater than each single index ( P<0.05). Conclusions:The levels of NLR, hs-CRP, IL-6 and PCT in peripheral blood of children with NPM are significantly correlated with brain injuries, and have certain predictive efficacy in predicting the risk of hydrocephalus.
