BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Peptide-based radiopharmaceuticals targeting integrin α5β1 show promise for precise tumor diagnosis and treatment. However, current peptide-based radioligands that target α5β1 demonstrate inadequate in vivo performance owing to limited tumor retention. The use of PEGylation to enhance the tumor retention of radiopharmaceuticals by prolonging blood circulation time poses a risk of increased blood toxicity. Therefore, a PEGylation strategy that boosts tumor retention while minimizing blood circulation time is urgently needed. Here, we developed a PEGylation-enabled peptide multidisplay platform (PEGibody) for PR_b, an α5β1 targeting peptide. PEGibody generation involved PEGylation and self-assembly. [⁶⁴Cu]QM-2303 PEGibodies displayed spherical nanoparticles ranging from 100 to 200 nm in diameter. Compared with non-PEGylated radioligands, [⁶⁴Cu]QM-2303 demonstrated enhanced tumor retention time due to increased binding affinity and stability. Importantly, the biodistribution analysis confirmed rapid clearance of [⁶⁴Cu]QM-2303 from the bloodstream. Administration of a single dose of [¹⁷⁷Lu]QM-2303 led to robust antitumor efficacy. Furthermore, [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 exhibited low hematological and organ toxicity in both healthy and tumor-bearing mice. Therefore, this study presents a PEGibody-based radiotheranostic approach that enhances tumor retention time and provides long-lasting antitumor effects without prolonging blood circulation lifetime. The PEGibody-based radiopharmaceutical [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 shows great potential for positron emission tomography imaging-guided targeted radionuclide therapy for α5β1-overexpressing tumors.

The activation proteins released by fibroblasts in the tumor microenvironment regulate tumor growth, migration, and treatment response, thereby influencing tumor progression and therapeutic outcomes. Owing to the proliferation and metastasis of tumors, fibroblast activation protein (FAP) is typically highly expressed in the tumor stroma, whereas it is nearly absent in adult normal tissues and benign lesions, making it an attractive target for precision medicine. Radiolabeled agents targeting FAP have the potential for targeted cancer diagnosis and therapy. This comprehensive review aims to describe the evolution of FAPI-based radiopharmaceuticals and their structural optimization. Within its scope, this review summarizes the advances in the use of radiolabeled small molecule inhibitors for tumor imaging and therapy as well as the modification strategies for FAPIs, combined with insights from structure-activity relationships and clinical studies, providing a valuable perspective for radiopharmaceutical clinical development and application.

Objective To analyze the adolescent tuberculosis reported in Haikou region between 2018 and 2021 and factors influencing the outcome. Methods The data on adolescent tuberculosis cases reported in Tuberculosis Information Management System in the Haikou Regional Centre for Disease Control and Prevention (RCDC) from 2018 to 2021 were collected. A follow-up survey was carried out until 31 December 2022. The changes in reported incidence of adolescent tuberculosis in Haikou was analyzed, and multivariate Cox proportional hazards regression models were used to identify independent factors influencing the outcome of adolescent tuberculosis. Results A total of 265 cases of tuberculosis in adolescents were reported between 2018 and 2021, of which 55 were reported in 2018, 74 in 2019, 67 in 2020, and 69 in 2021. The total number of reported cases of tuberculosis was 140 among male adolescents, which was slightly higher than 125 among female adolescents. The number of reported cases of tuberculosis was 134 in adolescents ≥15 years of age and 131 in adolescents <15 years of age. No statistically significant difference was reported between good outcome group and poor outcome group in age, gender, place of residence, nationality, and domicile place (P>0.05), whereas difference was found in the history of tuberculosis between two groups (P<0.05). Multivariate Cox proportional hazards regression model denoted that retreated tuberculosis (HR: 2.172, 95%CI: 1.483-3.007), complicating underlying disease (HR: 1.451, 95%CI: 1.080-1.985), and number of sputum smears (HR: 2.617, 95%CI: 1.531-3.458) were the risk factors for adverse outcomes in adolescent tuberculosis. Conclusion From 2018 to 2021, the number of reported adolescents of pulmonary tuberculosis in Haikou increased, suggesting that the management and prevention of adolescents should be strengthened to improve the prognosis rate of adolescents.

Objective:To study the life characteristics and related risk factors of patients with depression in Shandong Province.Methods:Based on the 2015 mental epidemiological survey database in Shandong Province,a total of 832 patients with depression,807 high-risk individuals with depression,and 819 low-risk individuals were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)and the Structured Clinical Interview for DSM-Ⅳ-TR Axis I Disorders,Research Version(SCID-I/P).In 2020,SCID-I/P was used for re diagnosis,and the General Health Questionnaire(GHQ-12),Simple Quality of Life question-naire,Pittsburgh sleep quality index(PSQI),Childhood Trauma Questionnaire(CTQ),Social Support Rating Scale(SSRS),Global Pain Scale(GPS),Montreal Cognitive Assessment(MoCA),Simplified Coping Style Question-naire(SCSQ)were used for evaluation.Compare changes in the quality of life of depression patients and construct a risk factor model.Results:Patients with depression had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in the high-and low-risk groups,those in remission of depression had higher scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in non-re-mission,and those with new-onset disorder in the high-and low-risk groups had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those with no-onset disorder(Ps＜0.001).Depres-sion diagnosis and PSQI scale scores at baseline negatively predicted at retest after 5 years(β=-0.06,-0.15),while coping style tendencies at baseline positively predicted(β=0.06).The simple quality of life questionnaire at baseline negatively predicted depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,and PSQI scale scores at retest after 5 years(β=-0.11,-0.17,-0.09),while the simple quality of life question-naire at baseline positively predicted coping style tendencies at retest after 5 years(β=0.13).Depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,PSQI scale scores at retest after 5 years,coping style tendencies at retest after 5 years,SSRS scale scores,CTQ scale scores,GPS scale scores,and the simple quality of life questionnaire at baseline all influenced the simple quality of life questionnaire at retest after 5 years through ei-ther direct or indirect pathways.Conclusion:It suggest that the quality of life is lower in patients with depression than in the general population.Depression diagnosis,sleep,mental health,pain,social support,childhood trauma and coping are direct and indirect risk factors affecting life.

Objective: To explore the correction factors of lung cancer caused by radon exposure in a uranium mine, and estimate the excess relative risk (ERR) coefficient of lung cancer caused by radon in the uranium miners. Methods: Male miners who worked in a uranium mine more than one year in Hunan Province from 1958 to 2018 were selected. This study preliminarily estimated the ERR coefficient of lung cancer caused by radon in the miners with different corrections using the Possion regression model. Results: This study cohort included 4 851 uranium miners, with 187 miners died with lung cancer from 1958 to 2018, and cumulative follow-up of 207 251 person-year. The ERR coefficient of lung cancer caused by radon without correction factors was estimated to be 0.21%/WLM (95%CI: 0.04%/WLM-0.27%/WLM). In the final model, the exponential correction factors of radon-induced lung cancer were time since exposure and exposure rate. In this model, if time since exposure was 45 years and the average exposure rate was 0.14 WL, the estimated ERR coefficient was 1.73%/WLM (95%CI: 0.36%/WLM-3.11%/WLM). The ERR decreases by about 60.00% for every 10 years since exposure, and increases by about 30.00% for every one WL increase exposure rate. Conclusion: The correction factors of lung cancer caused by radon in uranium miners in this mine were the time since exposure and exposure rate. It was preliminarily estimated that the ERR coefficient of lung cancer caused by radon in the occupational radon exposed population in this uranium mine was 1.73%/WLM (95%CI: 0.36%/WLM-3.11%/WLM).

Objective:To evaluate the application effect of mini-clinical exercise assessment (Mini-CEX) in clinical teaching of pediatrics of Chinese medicine, further optimize Mini-CEX scale with characteristics of pediatrics of Chinese medicine, and improve teachers' understanding of its connotation.Methods:A total of 50 pediatric clinical practice undergraduates were randomly divided into Mini-CEX group and control group, 25 in each group, with a total of 4 weeks of practice. The application effect of Mini-CEX was evaluated by clinical comprehensive ability assessment, and the students' evaluation on the introduction of Mini-CEX in clinical teaching was understood through questionnaire survey on the recognition, advantages and existing problems of various contents of Mini-CEX. SPSS 17.0 was used for t test and chi-square test. Results:Total scores and sub-item scores of clinical comprehensive ability examination in Mini-CEX group were higher than those in control group ( P < 0.05), and the satisfaction with teaching in Mini-CEX group was significantly higher than that in control group ( P < 0.05). Through the questionnaire, it was found that the students had a high degree of recognition for the items in the improved Mini-CEX scale, and thought it was more suitable for the internship study and effect evaluation of pediatrics of Chinese medicine, especially in the aspects of clinical communication skills and humanistic care. Conclusion:Mini-CEX has many advantages, such as improving the clinical comprehensive ability of undergraduates, teaching effect, flexible teaching methods, objective evaluation methods and focusing on the cultivation of doctor-patient communication skills, which is worthy of clinical promotion.

Objective:To investigate the clinical phenotype of a child with Jansen-de Vries syndrome, to clarify its genetic diagnosis and genetic characteristics, and to improve the understanding of this disease.Methods:Clinical data from a child with Jansen-de Vries syndrome diagnosed in the Children′s Affiliated Hospital of Zhengzhou University in October 2019 were collected, using core family-complete exon genomics detection (Trio-WES) and chromosome copy number variation (CNV) analysis techniques for genetic testing for the child and her parents, generation Sanger sequencing for family member verification for possible pathogenic mutations, and clinical and molecular genetic analysis. The relevant reports of PPM1D gene mutation in patients with mental retardation were reviewed.Results:The proband was a 11-month-old girl, presenting with mental retardation, lagging speech and motor development, autistic behavior, gastrointestinal dysfunction, and short stature, low flat nose bridge, low ear, short finger syndrome.Trio-WES results of the core family of the child suggested that PPM1D was a new transcoding heterozygous mutation, PPM1D (NM-003620): c.1216delA (p.Thr406Profs *3), and the karyotype and CNV analysis of the chromosome were normal. Literature retrieval showed currently a total of 18 cases were reported PPM1D gene mutation of mental disorders, described in the online human Mendel database for developmental disorder associated with gastrointestinal dysfunction and pain threshold increases, the age distribution in the seven months to 21 years of age, clinical manifestation of mental retardation, increased pain threshold, abnormal behavior, feeding difficulties, visual impairment, short finger syndrome, a group of syndromes associated with short stature, fever or vomiting, and congenital deformities. Conclusions:Jansen-de Vries syndrome clinically presents mainly with overall retardation (mental retardation/backward delayed motor development, language development, low muscle tone), abnormal behavior (lonely sample behavior, autism), craniofacial malformations (broad forehead, low ear nose bridge, thin upper lip), short finger syndrome (short feet, pinky stubby), gastrointestinal dysfunction (milk overflow, feeding difficulties, constipation). The child was diagnosed as a newly transcoding heterozygous mutation of the PPM1D gene. The current treatment is mainly rehabilitation training, and growth hormone replacement therapy can be given to part of the short height disease. The PPM1D gene [PPM1D(NM-003620): c.1216delA(p.Thr406Profs *3)] is the genetic cause of the child.

Objective:To investigate the clinical characteristics and gene mutation of seven cases of CDKL5 gene related early-onset epileptic encephalopathy diagnosed by next-generation sequencing.Methods:The clinical data of children with early-onset epileptic encephalopathy from February 2018 to December 2019 in the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University were retrospectively analyzed. The whole exome sequencing method was used to analyze the entire exome of the proband, and seven cases of CDKL5 gene mutation positive were screened out, and Sanger sequencing verification on family members was performed to identify the source and the characteristics of gene mutations were analyzed.Results:Among the seven children diagnosed with CDKL5 gene related early-onset epileptic encephalopathy, the ratio of male to female was 2∶5, and the age of onset was 15 days to five months of birth. The clinical phenotypes all included different degrees of developmental delay and repeated seizures, which were manifested as general seizures, myoclonic seizures, convulsive seizures or focal seizures; the outcome of use of antiepileptic drugs to control seizures was poor, and some applications of ketogenic diet had better effects. CDKL5 gene mutation sites were all denovo mutations, including NM_003159: c.772_776del (p.K258Efs *10) frameshift mutation, NM_003159.2 (exon: 9-15) heterozygous deletion, CDKL5 hemizygous deletion, NM_003159: c.268 (exon5) G>T (p.E90 *, 941) and NM_003159: c.2578C>T (p.Q860 *, 171) nonsense mutation, NM_003159: c.211A>G (p.Asn71Asp) and NM_001323289: c.545T>C (p.L182P) missense mutation. Among them, c.772_776del (p.K258Efs *10), c.268 (exon5)G>T and c.2578C>T (p.Q860 *, 171) have not been reported. Conclusions:CDKL5 gene related early-onset epileptic encephalopathy is an early onset epilepsy, which is more common in women, and has different forms of seizures. The early electroencephalogram is characterized as severe abnormal brain discharge, and the disease progresses in various forms. There are no specific changes in head magnetic resonance imaging. Different gene mutation sites may lead to different phenotypes and prognostic differences. Many anti-epileptic treatments are ineffective, and ketogenic diets are effective for some patients.
