Cognitive dysfunction often occurs in Alzheimer's disease, Parkinson's disease, cerebrovascular disease, or other neurodegenerative diseases, and can significantly impact the life quality of patients and create serious social, psychological, and economic burdens for individuals and their families. Numerous studies have confirmed that exercise can slow the decline in cognitive function through multiple pathways, in which fibronectin type III domain-containing protein 5 (FNDC5) plays an important role. However, the current research on the modulation of FNDC5 by exercise and its ability to improve hippocampal cognitive function lacks a systematic and comprehensive understanding. Therefore, this review focuses on the latest research progress regarding the role of exercise-induced FNDC5 in cognitive function, systematically reviews the positive effects of FNDC5 on cognitive function impairment caused by various factors, and clarifies the specific mechanisms by which exercise-induced FNDC5 improves cognitive function by inhibiting neuroinflammation and improving hippocampal neurogenesis and hippocampal synaptic plasticity. Based on the existing literature, we also identify the areas that require further research in this field. Overall, this review provides a theoretical basis for exercise-based prevention and improvement of cognitive function impairment.

We retrospectively analyzed the clinical data of seven patients (four men and three women) with primary hyperoxaluria (PH) type 1 (PH1) in the Department of Nephrology of Zhongda Hospital, Southeast University from January 2018 to October 2023. The mean age at disease onset was 32.1 (range: 26-42) years. The mean age at diagnosis was 40.6 (range: 28-51) years. All patients initially had kidney stones, and three patients were found to have renal insufficiency at the time of disease onset. Among them, two patients underwent hemodialysis immediately. Symptoms at the first visit included bone pain ( n=7), joint pain or deformity ( n=5), fatigue ( n=5), hypotension ( n=3), and subcutaneous nodules ( n=2). Four patients had a family history of PH. All patients had varying degrees of anemia (60-114 g/L), significant hypoalbuminemia (16.5-32.1 g/L), and hypercoagulable state (D-dimer: 2 230-12 781 μg/L). Seven patients received maintenance hemodialysis; their mean age was 37.7 (range: 26-50) years. The mean duration from disease onset to hemodialysis was 5.6 (range: 0-20) years. Five patients repeatedly experienced dialysis access dysfunction. Three patients underwent kidney transplantation before a diagnosis was made, and all transplanted kidneys lost function due to oxalate deposition. The mean follow-up duration was 14.43 (range: 4-38) months. Unfortunately, one patient died. All seven patients underwent computed tomography of the abdomen. All patients suffered skeletal abnormalities, bilateral nephrolithiasis, and nephrocalcinosis. Six patients carried AGXT gene mutations, including four compound heterozygous mutations and two pure homozygous mutations.The mutation sites included: c.823-824dup.AG (p.S275Rfs*38)(exon 8), c.815-816ins.GA (p.S275Rfs*38)(exon 8), c.595G>A (p.G199S) (exon 5), c.32C>G (p.P11R) (exon 1), and c.638C>T (p.A213V)(exon 6). According to the American College of Medical Genetics and Genomics guidelines, two loci were identified as likely pathogenic variants, seven were identified as pathogenic variants, and one locus was identified as having uncertain significance. In addition, patients 1 and 4 underwent skin biopsy, patient 2 underwent renal transplant biopsy, and patient 3 underwent bone marrow biopsy. Interestingly, significant oxalate deposition was found in the tissues. Therefore, PH1 is a rare autosomal recessive inherited disease. This study not only enhanced the understanding of the clinical characteristics of PH1 patients but also had great significance in early diagnosis and treatment of the disease.

OBJECTIVE: We aimed to understand the willingness and barriers to the acceptance of tuberculosis (TB) preventive treatment (TPT) among people with latent TB infection (LTBI) in China. METHODS: A multicenter cross-sectional study was conducted from May 18, 2023 to December 31, 2023 across 10 counties in China. According to a national technical guide, we included healthcare workers, students, teachers, and others occupations aged 15-65 years as our research participants. RESULTS: Overall, 17.0% (183/1,077) of participants accepted TPT. There were statistically significant differences in the acceptance rate of TPT among different sexes, ages, educational levels, and occupations ( P < 0.05). The main barriers to TPT acceptance were misconceptions that it had uncertain effects on prevention (57.8%, 517/894), and concerns about side effects (32.7%, 292/894). CONCLUSION An enhanced and comprehensive understanding of LTBI and TPT among people with LTBI is vital to further expand TPT in China. Moreover, targeted policies need to be developed to address barriers faced by different groups of people.

Objective To investigate the effects of cardiopulmonary bypass (CPB) on the differentiation of T lymphocyte subsets and the expression of specific transcription regulator T-bet/GATA binding protein 3 (GATA3). Methods A prospective double-blind study was conducted. Patients with CPB pulmonary repair of ventricular septal defect (observation group) or off-pump ligation of ductus arteriosus (control group) with 20 cases each in the 150th Military Hospital from February 2015 to February 2016 were enrolled. The blood sampled was collected on the time of before operation, at the end of CPB or operation, 4 hours after operation, and 24 hours after operation. T lymphocytes were isolated, the helper T cell 1 (Th1) specific transcription factor T-bet mRNA, helper T cell 2 (Th2) specific transcription factor GATA3 mRNA expression and cytokine γ-interferon (IFN-γ) mRNA, interleukin-4 (IL-4) mRNA expression were measured by Northern Blot. Results Compared with before operation, expression levels of T-bet mRNA [integral gray values: (1.39±0.52)×105vs. (2.92±0.88)×105], IFN-γ mRNA [integral gray values: (3.68±0.65)×105vs. (6.10±0.93)×105] were decreased transiently at the end of CPB in the observation group (both P < 0.05), returned to preoperative levels at 24 hours after operation [integral gray values: (2.77±0.74)×105, (6.22±1.25)×105, respectively, both P > 0.05]; expression levels of GATA3 mRNA [integral gray values:(4.96±0.88)×105vs. (3.21±0.68)×105], IL-4 mRNA [integral gray values: (3.52±1.13)×105vs. (1.85±0.63)×105] were increased (both P < 0.05), recovered to the preoperative levels at 24 hours after operation [integral gray values: (3.11±0.51)×105, (1.93±0.84)×105, respectively, both P > 0.05]. There were no significant differences in the expressions of T-bet, GATA3, IFN-γ and IL-4 mRNA in the control group at each time points (all P >0.05). Conclusions CPB causes the imbalance of Th1, Tc1/Th2, Tc2 and pro-inflammatory and anti-inflammatory reactions specially, which participate the complication occurrence after CPB. The changing of T-bet/GATA3 may be the internal mechanism for these changes.

Objective To observe the clinical efficacy of electroacupuncture at cervical Jiaji (EX-B2) points plus behavioral intervention in treating cervical spondylosis. Method The cervical spondylosis patients were randomized into two groups at a ratio of 3:1, 90 cases in the electroacupuncture group and 30 cases in the medication group. The patients who received electroacupuncture were also given cupping and behavioral intervention (raising head for 1 min every 20-30 min and correcting sleep habits). The clinical efficacy was evaluated according to the symptoms and body signs assessment scale. Result Respectively after 4-week, 8-week, 4-month and 6-month treatments, the clinical control rate, markedly control rate and total effective rate in the electroacupuncture group were significantly higher than that in the medication group. Conclusion Electroacupuncture at Jiaji points plus behavioral intervention is an effective solution to prevent and treat cervical spondylosis.

Objective To investigate the potential role of CXC chemokine ligand 16 (CXCL16)/CXC chemokine receptor 6 (CXCR6) pathway in the progression of diabetic nephropathy (DN). Methods 8?week old male db/db mice were randomly divided into DN group and DN inflamed group. 10% casein was subcutaneously injected to induce the DN mouse model with inflammation. In vitro, HK?2 cells were treated with high glucose (HG), and IL?1β+HG to investigate the effect of inflammatory stress on HK?2 cells. Further knockdown CXCL16 was mediated by RNA interference to determine the effects of CXCl16, then cells were divided into HG+IL?1βgroup, HG+IL?1β + siCXCL16 group and HG + IL?1β + vehicle group. Changes of renal function in mice were assessed by 24 h proteinuria and N?acetyl?β?D?glucosaminidase (NAG) during 8 weeks. The ultra?microstructure was checked by electron microscopy at 8th week. Lipid accumulation in kidneys and HK?2 were observed by Filipin staining and quantitative assay of intracellular free cholesterol. The protein expressions of CXCl16, CXCR6, a disintegrin and metalloproteinase?10 (ADAM10), fibronectin and α smooth muscle actin (α?SMA) in renal tissue were detected by immunohistochemistry and Western blotting. The mRNA and protein expressions of CXCl16, CXCR6, ADAM10, fibronectin andα?SMA in HK?2 cells were detected by real?time PCR and Western blotting, and protein expressions of CXCl16, CXCR6 and ADAM10 in HK?2 cells were also tested by cell immunofluorescence. Results Mice in DN inflamed group had higher 24 h proteinuria and NAG than those in DN group, and the differences between two groups shown statistical significance at 8th week (all P<0.05). Compared with DN mice, DN inflamed mice had more vacuoles within renal tubular cells, with mitochondrial swelling, deformation and decrease. Lipid accumulation and protein expressions of fibronectin and α?SMA were increased in DN inflamed group when compared with DN group (all P<0.05). Further, the expressions of CXCL16, CXCR6, ADAM10 were significantly increased in DN inflamed group (all P<0.05). In vitro, the mRNA and protein expressions of CXCL16, CXCR6, ADAM10, fibronectin and α?SMA, and lipid accumulation were increased in high glucose plus IL?1βgroup when compared with high glucose group (all P<0.05). However, after siRNA of CXCL16 transfection, the mRNA and protein expressions of CXCL16, CXCR6, ADAM10, fibronectin andα?SMA were down?regulated in HG+IL?1β+siCXCL16 group as compared with high glucose+IL?1βgroup (all P<0.05). Furthermore, lipid accumulation was decreased (P<0.05). Conclusion Inflammation accelerates tubulointerstitial injury in DN partly through the activation of CXCL16 pathway, which may facilitate the lipid accumulation in tubular epithelial cells.
