Objective To evaluate the clinical manifestations, metal metabolism, imaging characteristics and treatment response in patients with delayed Wilson disease (WD). Methods Patients with untreated WD (40 with delayed onset and 40 with non?delayed onset) were enrolled. Twenty healthy people were included as normal controls. All patients were evaluated with modified Young scale neural symptom scores, grade of Child liver function and mental symptoms rating scale, magnetic resonance imaging (MRI) scan, magnetic sensitive imaging (susceptibility weighted imaging, SWI), metal metabolism. Corrected phase (CP) was measured at SWI. After 2 week treatment, neurologic symptoms, liver function, and metal metabolism were reviewed. Results The total score of neurological symptoms in WD patients with delayed onset was lower than that of non?delayed onset (13.00 ± 6.87 vs. 21.13 ± 5.53, P=0.033). The scores of SCL?90 and HAMA depression scales in patients with delayed onset were lower than those of non?delayed onset. On T2 weighted imaging, areas including substantia nigra and thalamus, the caudate nucleus, globus pallidus, putamen presented high signal rate in patients with delated onset than those with non?delayed (P=0.022, 0.037, 0.022, 0.037, 0.029 respectively). The SWI CP values of cangbai sphere and shell nucleus in patients with delayed onset were lower than those with non?delayed onset. Patients with delayed onset had higher urinary copper than those with non?delayed onset before and after treatment (P=0.040, 0.036). After treatment, the score of abnormal tremor and gait in patients with delayed onset was decreased (P=0.037, 0.044), while as the occurrence of neurological symptoms was increased by 10%, and the liver function level in patients with delayed WD was decreased in 3 cases. Conclusions The brain of WD patients with delayed onset is mainly composed of metal deposits, however the cell damage is not apparent. Clinical symptoms are characterized by significant liver injury, but relatively mild neurological and psychiatric symptoms. Patients with delayed WD have higher urinary copper excretion than those with non?delayed WD. Chelating agents improves the neurological symptoms in patients with delayed onset.

Sialidosis is a rare autosomal recessive disorder which is classified into type Ⅰ and Ⅱ according to the age of onset and severity of the disease.Type I,also known as mucolipidosis,is often manifested as myoclonus,ataxia,general tonic clonic seizure,and bilateral cherry-red spots in eye examination.Four cases of type Ⅰ sialidosis were reported in order to improve the diagnosis and treatment of this disease.Patients were mainly manifested as myoclonus and ataxia.Whole exon gene sequencing of the four patients all showed the mutation c.544A＞G in the NEU1 gene.Meanwhile,the new mutation c.596G＞A carried was found in case 2 and its pathogenicity was also analyzed.Finally,we summarized the clinical characteristics of type Ⅰ patients in China,noting that most patients develop all the core symptoms as the disease progresses.

The Health-Related Quality of Life (HRQoL) pertains to patients' subjective contentment concerning their physical, psychological, and social well-being throughout disease treatments. Predominantly employed HRQoL metrics in spinal metastases comprise the 36-item Short-Form Health Survey (SF-36), EuroQoL Five Dimensions Questionnaire (EQ-5D), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), and the Functional Assessment of Cancer Therapy-General (FACT-G). In clinical applications, due to their broad application and diverse disease types, combined with the lack of specificity in the scale content and the prolixity of their questionnaires, these tools often fail to capture the nuanced experiences of patients, thereby compromising the reliability and validity of the results. The Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ), developed by the Spine Oncology Study Group, offers a tailored metric for spinal metastases, encapsulating both specificity and inclusivity. Its proven robust reliability and validity make it invaluable for decision-making and therapeutic efficacy appraisals. The Patient-Reported Outcome Measurement Information System (PROMIS), a novel metric suitable across many medical disciplines, facilitates cross-sector data acquisition, substantially augmenting the precision, sensitivity, and credibilityof assessments, and is pivotal in clinical investigations and interventions. As it continually evolves, PROMIS consistently outperforms traditional metrics in evaluative capacities, exhibiting impressive and consistent proficiency in prognostications, preoperative assessments, and therapeutic outcome evaluations within the spinal metastasis domain. Presently, Chinese research on the HRQoL of spinal metastasis patients remains scant, and choosing an apt, precise, and dependable metric holds significant clinical relevance. Drawing upon extant scholarly publications, this review concluded the current global HRQoL tools for spinal metastases, aiming to furnish insights for the clinical management and research pertaining to spinal metastases.
