Objective:To explore the clinical, imaging, and genetic characteristics of an adult patient with sporadic Neuronal intranuclear inclusion disease (NIID).Methods:A patient who had visited the First People′s Hospital of Chenzhou on August 6, 2023 was selected as the study subject. Results of clinical examination, neuroimaging, and genetic testing were retrospectively analyzed along with a literature review. The number of GGC trinucleotide repeats in the 5′-untranslated region of the NOTCH2NLC gene was determined by GC-PCR. Results:The patient had presented with episodic encephalopathy, with enhanced magnetic resonance imaging showing enhancement features of the posterior cerebral cortex during the period of acute episode. Genetic testing revealed an increased number of GGC repeats ( n = 97) in the 5′- untranslated region of the NOTCH2NLC gene, which confirmed the diagnosis of NIID. Conclusion:Clinical attention should be paid to the enhanced MRI findings of patients with adult-onset NIID, for whom posterior cortical enhancement may be characteristic manifestation during the acute phase of encephalopathy-like episode.

Pulmonary fibrosis (PF) is the pathological structure of incurable fibroproliferative lung diseases that are attributed to the repeated lung injury-caused failure of lung alveolar regeneration (LAR). Here, we report that repetitive lung damage results in a progressive accumulation of the transcriptional repressor SLUG in alveolar epithelial type II cells (AEC2s). The abnormal increased SLUG inhibits AEC2s from self-renewal and differentiation into alveolar epithelial type I cells (AEC1s). We found that the elevated SLUG represses the expression of the phosphate transporter SLC34A2 in AEC2s, which reduces intracellular phosphate and represses the phosphorylation of JNK and P38 MAPK, two critical kinases supporting LAR, leading to LAR failure. TRIB3, a stress sensor, interacts with the E3 ligase MDM2 to suppress SLUG degradation in AEC2s by impeding MDM2-catalyzed SLUG ubiquitination. Targeting SLUG degradation by disturbing the TRIB3/MDM2 interaction using a new synthetic staple peptide restores LAR capacity and exhibits potent therapeutic efficacy against experimental PF. Our study reveals a mechanism of the TRIB3-MDM2-SLUG-SLC34A2 axis causing the LAR failure in PF, which confers a potential strategy for treating patients with fibroproliferative lung diseases.

Objective:To analyze the detection rate of hyperuricemia (HUA) and the distribution of serum uric acid (SUA) levels by multiple correlation analysis in middle-aged and elderly population receiving health examination.Methods:In this cross-sectional study, the study object were 25 587 middle-aged and elderly people who receiving health examination in Nanfang Hospital from January to December in 2014. According to the latest diagnostic criteria, the population was divided into HUA and non-HUA groups. Furthermore, the subjects were divided into 4 groups with the level of SUA (Q 1: SUA<313 μmol/L, Q 2:313 μmol/L≤SUA<375 μmol/L, Q 3:375 μmol/L≤SUA<440 μmol/L, Q 4: SUA≥440 μmol/L). According to the data types, two independent sample t test, Mann-Whitney U test, Chi-square test and multiple correspondence analysis were used for statistical analysis. Results:The mean age of the study subjects was (54.78±8.80) years with 16 570 males (64.8%) and 9 017 females (35.2%). The overall detection rate of HUA was 31.5%, and it was higher in men (43.1%) than in women (10.1%). The body mass index(BMI), systolic blood pressure, diastolic blood pressure, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and fasting blood glucose (FBG) in the HUA group were all higher than those in the non-HUA group (all P<0.001); and high-density lipoprotein cholesterol (HDL-C) was lower than that in the non-HUA group( P<0.001). In multiple correspondence analysis, Cronbach′s α coefficients of the first dimension and the second dimension was 0.608 and 0.237, respectively. Further analysis was performed stratified by gender, it indicated that 45-<55 years old male and overweight were closely associated with the Q 3 group, fatty liver and hyperlipidemia were closely associated with Q 4 group; the 55-<65 years old female, hyperlipidemia, fatty liver and obesity were closely associated with the Q 3 group, while hyperglycemia and hypertension were closely associated with the Q 4 group. Conclusion:The detection rate of HUA in middle-aged and elderly population receiving health examination was high, and the detection rate of HUA in male was higher than that in female. SUA levels are higher in middle-aged and elderly men who have fatty liver and hyperlipidemia. While SUA levels are higher in middle-aged and elderly women who have hyperglycemia and hypertension.

Objective:To explore the clinical and imaging characteristics of patients with unruptured intracranial aneurysms accompanied by sentinel headache.Methods:Forty patients with unruptured intracranial aneurysms confirmed by DSA/CTA and accompanied by sentinel headache admitted to Department of Neurology, First Affiliated Hospital of Xiangnan University from January 2018 to August 2023 were selected as the study subjects; the clinical and imaging characteristics of these patients were summarized. Forty-four patients with unruptured intracranial aneurysms without sentinel headache and 40 patients with subarachnoid hemorrhage caused by ruptured intracranial aneurysms admitted to the hospital at the same period were selected as controls. The differences in aneurysm length (maximum diameter), morphology, tumor length (maximum diameter)/neck width (AR), and risk score for rupture of intracranial aneurysms (scores of population, hypertension, age, size of aneurysm, earlier aneurysm rupture, site of aneurysm [PHASES]) among the 3 groups were analyzed.Results:Among the 40 patients with unruptured intracranial aneurysms accompanied by sentinel headache, 20 (50%) presented with pain localized at the lateral frontal and orbital regions, 3 (7.5%) with pain at the posterior neck region, and 17 (42.5%) with irregular headache sites; 34 (85%) had new onset headache, and 6 (15%) had changes in headache nature besides chronic headache; 24 patients (60%) had posterior communicating artery aneurysm, 12 (30%) had internal carotid artery aneurysm, 1 (2.5%) had middle cerebral artery aneurysm, and 3 (7.5%) had vertebral artery dissection aneurysm; 36 (90%) had irregular aneurysm morphology. Compared with patients with unruptured intracranial aneurysms without sentinel headache, patients with unruptured intracranial aneurysms accompanied by sentinel headache and those with subarachnoid hemorrhage caused by ruptured intracranial aneurysms had larger aneurysm length (maximum diameter), higher proportion of irregular morphology, higher AR value, and higher PHASES scores, with significant differences ( P<0.05). Compared with patients with subarachnoid hemorrhage caused by ruptured intracranial aneurysms, patients with unruptured intracranial aneurysms accompanied by sentinel headache had larger aneurysm length (maximum diameter) and higher PHASES scores, with significant differences ( P<0.05). Conclusion:Sentinel headache is common in patients with unruptured posterior communicating artery aneurysms, and the relatively specific headache pattern is sudden periorbital pain or posterior neck pain; patients with unruptured intracranial aneurysms accompanied by sentinel headache have a higher rupture risk due to the larger size, more irregular shape, higher AR value of the aneurysm, therefore, same attention should be payed to these patients as those with ruptured aneurysms in clinical practice.

Background::The risk for chronic kidney disease (CKD) is influenced by genetic predisposition, sex, and lifestyle. Previous research indicates that coffee is a potentially protective factor in CKD. The current study aims to investigate whether sex disparity exists in the coffee–CKD association, and whether genetic risk of CKD or genetic polymorphisms of caffeine metabolism affect this association.Methods::A total of 359,906 participants from the UK Biobank who were enrolled between 2006 and 2010 were included in this prospective cohort study, which aimed to estimate the hazard ratios for coffee intake and incident CKD using a Cox proportional hazard model. Allele scores of CKD and caffeine metabolism were additionally adjusted for in a subsample with qualified genetic data ( n = 255,343). Analyses stratified by genetic predisposition, comorbidities, and sex hormones were performed. Tests based on Bayesian model averaging were conducted to ascertain the robustness of the results. Results::Coffee was inversely associated with CKD in a dose-dependent manner. The effects of coffee did not differ across different strata of genetic risk for CKD, but were more evident among slower genetically predicted caffeine metabolizers. Significant sex disparity was observed ( P value for interaction = 0.013), in that coffee drinking was only associated with the risk reduction of CKD in females. Subgroup analysis revealed that testosterone and sex hormone-binding globulin (SHBG), but not estradiol, modified the coffee–CKD association. Conclusions::In addition to the overall inverse coffee–CKD association that was observed in the general population, we could also establish that a sex disparity existed, in that females were more likely to experience the benefit of the association. Testosterone and SHBG may partly account for the sex disparity.

Objective:To investigate the clinical and imaging features of spontaneous convexal subarachnoid hemorrhage (cSAH) with acute cerebral infarction.Methods:Nine patients with cSAH complicated with acute cerebral infarction, admitted to our hospital from January 2018 to October 2021, were selected. The clinical data and efficacy of these patients were retrospectively analyzed.Results:The time from cSAH to the onset of acute cerebral infarction was 5-144 h, with median time of 2 d. The most common bleeding site of cSAH was the parietal lobe ( n=6); cSAH in the ipsilateral side of acute cerebral infarction was noted in 4 patients. Six patients had middle cerebral artery stenosis or occlusion, and 2 patients had anterior cerebral artery stenosis or occlusion. Hypertension ( n=7) was the most common primary disease; 7 patients were treated with antiplatelet drugs, anticoagulants and/or stents. The follow-up at 3 months after cSAH showed that 6 patients had good prognosis and one had poor prognosis. Conclusions:The cSAH often occurs 2 d after acute cerebral infarction; intracranial artery stenosis or occlusion may be the main cause of the disease. In patients complicated with cSAH, active antiplatelet, anticoagulation and/or stent therapy do not increase the risk of bleeding, and the prognosis is good.

Objective: To investigate the effect of low level laser on osteoclast and collagen fiber remodeling during the process of tooth retention after tooth movement in rats and to provide the experimental basis for clinical application. Methods : In total, 20 eight-week-old Wistar rats were selected to establish a mesial movement model of the maxillary first molar and then randomly divided into four groups after the appliance was removed. In total, 5 rats were included in each group, including baseline group (without force as blank control), control group (without any intervention after removing the force appliance), retention group (teeth were wrapped with orthodontic ligature wires that were screwed into hemp flower as fixed retention to maintain the space between the first molar and incisor after appliances were removed) and retention and low energy laser irradiation group (teeth were wrapped with the orthodontic ligature wires that were screwed into hemp flower as fixed retention and low energy laser irradiation was applied on days 0, 3, 6, 9 and 12 after appliance removal). Two weeks later, all the rats were sacrificed and the first molar tissue blocks of each group were collected. The distribution of osteoclasts and collagen fiber were studied by HE staining, TRAP staining and Masson staining to illustrate the process of alveolar bone and collagen fiber remodeling. Results : Two weeks after appliances were removed, collagen fibers were deposited on both sides of the root in the baseline group, but no osteoclasts were observed in the distal side of the root. In the control group, collagen fibers on the two sides of the root were not obvious and osteoclasts were active on the distal side. In the retention group, collagen fibers were obvious on the two sides of the root and the osteoclasts on the distal side were less active than the control group. Regarding the retention and low energy laser irradiation group, collagen fibers were significantly obvious and osteoclasts were not seen. The difference was statistically significant between the retention and low energy laser irradiation group and the other three groups (P＜0.05). Conclusion These results suggest that fixed retention with simultaneous low level laser can effectively promote the synthesis of collagen fibers and inhibit the activity of osteoclasts during the process of tooth retention after movement, thus reducing the possibility of molar recurrence.
