IntroductionAchieving a goal of serum urate levels in patients with gout is an important way to prevent gout and its complications while it remains difficult with a low targeting rate worldwidely. Currently, hyperuricemia classification has not been widely applied to the management of gout owing to insufficient clinical evidences. This study aimed to evaluate the effectiveness of achieving target urate based on hyperuricemia classification in Chinese patients with gout.MethodsIn this prospective study, patients with gout receiving urate lowering therapy with benzbromarone were assigned to two groups, a renal underexcretion and an unclassified type. The primary endpoint was the proportion of patients achieving the serum urate target (<360 μmol/L) during the 12-week study. The frequency of acute gout attacks as well as physical and chemical indicators were secondary endpoints.ResultsTarget serum urate level was achieved in 60.5% of underexcretors compared with 39.0% of patients of the unclassified type at week 12 (P = 0.002). Blood glucose and cholesterol levels were lower in the underexcretor group compared with the unclassified type group at the end of the trial, without significant different frequencies in gout flare during the study. In subgroup analysis, stratified by body mass index and estimated glomerular filtration rate, the proportion of patients with serum urate <360 μmol/L was greater in the underexcretion compared with the unclassified type group.ConclusionsThe increased achievement of target serum urate in the underexcretion group supports the use of a clinical hyperuricemia typing treatment strategy for gout.

Abstract Background Herein, we report two cases of unilateral retinal pigment epithelium dysgenesis (URPED) in Chinese patients and explore the relationship between URPED and combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). Case presentation The lesion margins in the two cases showed pathognomonic clinical features of URPED, namely, a scalloped reticular margin in hyperplastic retinal pigment epithelium and mild fibrosis. The hypoautofluorescence observed by fundus autofluorescence was inverted compared with that observed by fundus fluorescence angiography. A large amount of fibroglial proliferation and disorganization of the retina involving the whole layer, which are also found in peripapillary CHRRPE, were found in the lesions. Conclusions URPED appears to share some clinical features with CHRRPE, and the relationship between URPED and CHRRPE needs further study.

Objectives:Anti-dipeptidyl–peptidase–like protein 6 (anti-DPPX) encephalitis an extremely rare type of immune-mediated encephalitis. This study aimed to analyze the electroclinical characteristics and prognosis of anti-DPPX encephalitis.Methods:Five patients (all male) with anti-DPPX encephalitis in East China from January 2016 to October 2021 was retrospective analyzed. Electroclinical features and outcomes were reviewed.Results:All five patients were male. The media age at disease onset was 32 years old with a range of 14–56 years. The main symptoms included psychiatric disturbances (2/5), amnesia (4/5), confusion (3/5), and seizures (3/5). Migrating myoclonus were identified in patient 4 with positive DPPX and contactin-associated protein-like 2 antibodies in blood. All of the patients had positive DPPX antibodies in serum. Only one of them had positive antibody in the cerebrospinal fluid. EEG showed diffuse slowing in two patients, but no epileptiform discharges were observed. Eighty percent (4/5) of the patients showed normal brain magnetic resonance imaging. After immunotherapy, improvement of neuropsychiatric symptoms from all of the patients was observed. Over a mean follow-up of 30.8 weeks, all of the patients had marked improvement in the modified Rankin Scale. To date, no tumors were not observed in any patients.Conclusions:Anti-DPPX encephalitis mainly presents as neuropsychiatric symptoms. Cooperation of DPPX antibodies and CASPR2 antibodies might have contributed to the migration of myoclonus in the patient 4. Prompt immunotherapy often results in improvement.

Purpose: To investigate the effect of general and subarachnoid (spinal) anesthesia on the incidence of postoperative delirium and cognitive impairments in elderly Chinese patients. Methods: Elderly Chinese patients (n = 281) aged 65 – 79 years (mean age = 74.12 ± 4.15 years) who underwent proximal femoral fracture surgery were recruited over a 1-year period for this study. The patients were evaluated using neuropsychological assessment battery (NAB) 24 h before surgery, and on the first day 1 month after surgery. Data on activity of daily living (ADL) (in this case toileting at the time of discharge) were recorded and analyzed. Results: There was no significant difference in the number of patients that developed postoperative delirium between the two anesthesia groups (p > 0.05). Although the trail making test (TMT) scores (parts A and B) were increased on the first day 1 month after surgery, there were no significant differences in NAB results between the two groups (p > 0.05). Patients who received subarachnoid (spinal) anesthesia had significantly higher dependency for toileting at the time of discharge than those who received general anesthesia (p < 0.05). Conclusion: These results show that general and subarachnoid (spinal) anesthesia do not cause postoperative delirium and cognitive dysfunction in elderly Chinese patients who underwent proximal femoral fracture surgery.

BackgroundParenchymal hemorrhage (PH) is a troublesome complication after endovascular treatment (EVT).ObjectiveTo investigate the incidence, independent predictors, and clinical impact of PH after EVT in patients with acute ischemic stroke (AIS) due to anterior circulation large vessel occlusion (LVO).MethodsSubjects were selected from the ANGEL-ACT Registry. PH was diagnosed according to the European Collaborative Acute Stroke Study classification. Logistic regression analyses were performed to determine the independent predictors of PH, as well as the association between PH and 90-day functional outcome assessed by modified Rankin Scale (mRS) score.ResultsOf the 1227 enrolled patients, 147 (12.0%) were diagnosed with PH within 12–36 hours after EVT. On multivariable analysis, low admission Alberta Stroke Program Early CT score (ASPECTS)(adjusted OR (aOR)=1.13, 95% CI 1.02 to 1.26, p=0.020), serum glucose >7 mmol/L (aOR=1.82, 95% CI 1.16 to 2.84, p=0.009), and neutrophil-to-lymphocyte ratio (NLR; aOR=1.05, 95% CI 1.02 to 1.09, p=0.005) were associated with a high risk of PH, while underlying intracranial atherosclerotic stenosis (ICAS; aOR=0.42, 95% CI 0.22 to 0.81, p=0.009) and intracranial angioplasty/stenting (aOR=0.37, 95% CI 0.15 to 0.93, p=0.035) were associated with a low risk of PH. Furthermore, patients with PH were associated with a shift towards to worse functional outcome (mRS score 4 vs 3, adjusted common OR (acOR)=2.27, 95% CI 1.53 to 3.38, p<0.001).ConclusionsIn Chinese patients with AIS caused by anterior circulation LVO, the risk of PH was positively associated with low admission ASPECTS, serum glucose >7 mmol/L, and NLR, but negatively related to underlying ICAS and intracranial angioplasty/stenting.Trial registration numberNCT03370939.

Abstract Background Retinopathy of prematurity (ROP) is a multifactorial retinal disease, involving both environmental and genetic factors; The purpose of this study is to evaluate the clinical presentations and genetic variants in Chinese patients with ROP. Methods A total of 36 patients diagnosed with ROP were enrolled in this study, their medical and ophthalmic histories were obtained, and comprehensive clinical examinations were performed. Genomic DNA was isolated from peripheral blood of ROP patients, polymerase chain reaction and direct sequencing of the associated pathogenic genes (FZD4, TSPAN12, and NDP) were performed. Results All patients exhibited the clinical manifestations of ROP. No mutations were detected in the TSPAN12 and NDP genes in all patients; Interestingly, three novel missense mutations were identified in the FZD4 gene (p.A2P, p.L79M, and p.Y378C) in four patients, for a detection rate of 11.1% (4/36). Conclusions This study expands the genotypic spectrum of FZD4 gene in ROP patients, and our findings underscore the importance of obtaining molecular analyses and comprehensive health screening for this retinal disease.
