Objective:To investigate the clinical manifestations, long-term survival, and prognosis of childhood T-cell acute lymphoblastic leukemia (T-ALL).Methods:Case summary.The clinical data of 43 T-ALL children who were diagnosed and treated in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2010 to December 2021 were retrospectively analyzed.They were stratified for treatment according to the CCCG-ALL regimen, and the correlation of prognosis with the condition at initial diagnosis, early treatment response, and induced remission was analyzed.The Kaplan-Meier survival curve was used to analyze the survival rate, and the survival rates were compared between groups by the Log-rank test.The multivariate Cox regression model was used to analyze the impact of multiple factors on the long-term survival of children.Results:T-ALL patients accounted for 9.5% (43/451) of the total number of acute lymphoblastic leukemia patients admitted to the hospital at the same period.The median onset age of the 43 T-ALL patients was 7 years (1-13 years).Of the 43 patients included, 14 patients (32.6%) had concomitant mediastinal widening, 8 patients (18.6%) had concomitant giant mediastinal masses, and 4 patients (9.3%) had early precursor T-cell acute lymphoblastic leukemia (ETP-ALL) at initial diagnosis.These 43 children were treated according to the CCCG-ALL intermediate- and high-risk group regimen.Among them, 33 children (76.7%) achieved sustained remission, 5 children died, and 5 children had a relapse.As of September 30, 2024, the median follow-up time was 62 months (1-170 months), the 10-year event-free survival rate was (80.2±6.4)%, and the 10-year overall survival rate was (86.6±5.8)%.The median relapse time and 10-year cumulative relapse rate of the 5 relapsed children were 28 months (7-58 months) and (13.7±5.8)%, respectively.The relationship of prognosis with clinical characteristics at initial diagnosis and induced remission in 43 T-ALL children was analyzed.The results showed that patients aged ≥10 years, with a grade-1 non-central nervous system at initial diagnosis, ETP-ALL, abnormal chromosome number and structure, non-M1 status of bone marrow and minimal residual disease (MRD)≥ 1% on day 19 of induction treatment, and MRD ≥ 0.01% on day 46 to 55 of induction treatment had poorer long-term survival(all P<0.05).The multivariate analysis showed that age ≥10 years, ETP-ALL, and abnormal chromosome number and structure were risk factors of poor prognosis ( P=0.045, 0.030, 0.021). Conclusions:The CCCG-ALL regimen has a good overall therapeutic effect in children with T-ALL.Age ≥10 years, abnormal chromosome number and structure, ETP-ALL, grade-1 non-central nervous system at initial diagnosis, and early remission are risk factors of poor prognosis.Treatment after relapse in children with T-ALL is difficult.

OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

OBJECTIVE: The objective of our study was to evaluate the vaccine effectiveness (VE) of the pentavalent rotavirus vaccine (RV5) among < 5-year-old children in three provinces of China during 2020-2024 via a propensity score-matched test-negative case-control study. METHODS: Electronic health records and immunization information systems were used to obtain data on acute gastroenteritis (AGE) cases tested for rotavirus (RV) infection. RV-positive cases were propensity score matched with RV-negative controls for age, visit month, and province. RESULTS: The study included 27,472 children with AGE aged 8 weeks to 4 years at the time of AGE diagnosis; 7.98% (2,192) were RV-positive. The VE (95% confidence interval, CI) of 1-2 and 3 doses of RV5 against any medically attended RV infection (inpatient or outpatient) was 57.6% (39.8%, 70.2%) and 67.2% (60.3%, 72.9%), respectively. Among children who received the 3rd dose before turning 5 months of age, 3-dose VE decreased from 70.4% (53.9%, 81.1%) (< 5 months since the 3rd dose) to 63.0% (49.1%, 73.0%) (≥ 1 year since the 3rd dose). The three-dose VE rate was 69.4% (41.3%, 84.0%) for RVGE hospitalization and 57.5% (38.9%, 70.5%) for outpatient-only medically attended RVGE. CONCLUSION Three-dose RV5 VE against rotavirus gastroenteritis (RVGE) in children aged < 5 years was higher than 1-2-dose VE. Three-dose VE decreased with time since the 3rd dose in children who received the 3rd dose before turning five months of age, but remained above 60% for at least one year. VE was higher for RVGE hospitalizations than for medically attended outpatient visits.

Objective:To optimize the previously established Improved Membrane Filtration(ISET)method for de-tecting circulating tumor cells(CTCs)and to develop and validate a new,reliable CTC detection method by combining it with immunofluorescence techniques.Methods:The study involved optimizing the CTC detection system using mixed samples of gastric cancer 803 cell lines and peripheral blood(PB)from healthy volunteers to simulate the peripheral blood of cancer patients.The optimized system was validated using peripheral blood samples from 23 patients with ad-vanced(Ⅲ/Ⅳ)cancer,employing the ISET technique combined with immunocytochemistry(ICC)and paraffin block im-munohistochemistry(IHC)identification techniques.A cohort of 74 patients with various cancer types was used to com-pare the diagnostic performance of the membrane filtration combined with immunofluorescence(ISET-ICC)system against the CTC-Biopsy and CellSearchTM methods.Results:By adding a red blood cell lysis step and increasing the membrane pore size to 10 μm,the filtration time of the ISET method was reduced by threefold.The ISET-ICC detection method achieved a CTC positivity rate of 65.2％.The combination of the ISET-ICC system with the cell paraffin block-IHC method enhanced the reliability of identifying circulating tumor cells undergoing epithelial-mesenchymal transition(EMT-CTCs).The ISET-ICC technique demonstrated a significantly higher CTC positivity rate(17.6％;13/74)within the study cohort compared to the CellSearchTM method,which showed a CTC positivity rate of 12.2％(9/74;x2=10.21,P=0.007).The difference in positive detection rates among patients at different stages was statistically significant(x2=3.64,P=0.029),with a notably higher CTC detection rate in stage Ⅳ patients compared to those in stages Ⅰ-Ⅲ(x2=6.76,P=0.001).Conclusion:The improved ISET-ICC system effectively detects CTCs across various cancer types and dem-onstrates greater accuracy compared to the CellSearchTM system.

The AP2/ERF transcription factor family is a class of transcription factors widely present in plants, playing a crucial role in regulating flowering, flower development, flower opening, and flower senescence. Based on transcriptome data from flower, leaf, and stem samples of two Lonicera macranthoides varieties, 117 L. macranthoides AP2/ERF family members were identified, including 14 AP2 subfamily members, 61 ERF subfamily members, 40 DREB subfamily members, and 2 RAV subfamily members. Bioinformatics and differential gene expression analyses were performed using NCBI, ExPASy, SOMPA, and other platforms, and the expression patterns of L. macranthoides AP2/ERF transcription factors were validated via qRT-PCR. The results indicated that the 117 LmAP2/ERF members exhibited both similarities and variations in protein physicochemical properties, AP2 domains, family evolution, and protein functions. Differential gene expression analysis revealed that AP2/ERF transcription factors were primarily differentially expressed in the flowers of the two L. macranthoides varieties, with the differentially expressed genes mainly belonging to the ERF and DREB subfamilies. Further analysis identified three AP2 subfamily genes and two ERF subfamily genes as potential regulators of flower development, two ERF subfamily genes involved in flower opening, and two ERF subfamily genes along with one DREB subfamily gene involved in flower senescence. Based on family evolution and expression analyses, it is speculated that AP2/ERF transcription factors can regulate flower development, opening, and senescence in L. macranthoides, with ERF subfamily genes potentially serving as key regulators of flowering duration. These findings provide a theoretical foundation for further research into the specific functions of the AP2/ERF transcription factor family in L. macranthoides and offer important theoretical insights into the molecular mechanisms underlying floral phenotypic differences among its varieties.

Objective:To explore the clinical features of Brucellar myelitis and diagnosis and treatment of secondary neuromyelitis optica spectrum disorder (NMOSD), and enhance the awareness of clinicians about this disease.Methods:A retrospective study was performed; 13 patients with Brucellar myelitis admitted to Department of Neurology, Inner Mongolia Autonomous Region People's Hospital from January 2020 to December 2024 were chosen. Clinical data were collected, and MRI images and serological changes during the infection period were observed. Serum and cerebrospinal fluid demyelinating antibody markers and cerebrospinal fluid oligoclonal bands (OCBs) in the suspected secondary inflammatory demyelinating diseases of the central nervous system patients were detected. All patients received standard antibiotic treatment and/or individualized immunotherapy depending on disease severity. The patients were followed up for 24 (12, 42) months. At the last follow-up, the neurological outcomes were evaluated using modified Rankin scale (mRS, scores of 0-2: good prognosis; scores of 3-6: poor prognosis).Results:(1) Among the 13 patients, 12 had motor disorder, 9 had bladder/bowel dysfunction, 7 had sensory abnormality, and 4 had other symptoms such as dizziness, behavioral changes, or unsteady gait. (2) MRI results showed that 8 patients had spinal cord abnormalities, including 2 with long-segment intramedullary high signal at T2-weighted image and 6 with short-segment local intramedullary high signal at T2-weighted image. Enhanced MRI was performed in 11 patients, with 2 showing lesion enhancement, 3 showing meningeal enhancement, and 6 showing no enhancement. (3) Four patients had elevated cerebrospinal fluid pressure (>180 mmH 2O); 9 patients had elevated cerebrospinal fluid protein level (>0.45 g/L). Brucella-specific DNA was detected in the cerebrospinal fluid of 6 patients. One patient was positive for OCB type II. One patient was positive for aquaporin 4 antibody (AQP4-IgG) in both serum and cerebrospinal fluid, and one patient was double positive for myelin oligodendrocyte glycoprotein antibody (MOG-IgG) and AQP4-IgG in serum. (4) All 13 patients received standard antibiotic treatment; 12 patients received immunotherapy. (5) Among the 4 patients with poor prognosis, 3 died and the remaining 9 had a good prognosis. The mRS score decreasing from 4 (3, 4) at admission to 2 (2, 3) at the last follow-up, showing an overall improvement in neurological function. (6) Among the 13 patients, 2 were diagnosed as having Brucellar myelitis secondary NMOSD. On the basis of antibiotic treatment, one AQP4-IgG positive patient was treated with high-dose glucocorticoids only and later died; one MOG-IgG and AQP4-IgG double positive patient was treated with intravenous immunoglobulin combined with high-dose glucocorticoids and sequential rituximab, with mRS score decreasing from 5 at admission to 2 at the last follow-up and good neurological function recovery. Conclusions:The clinical manifestations of Brucellar myelitis are diverse and overlap with the clinical features of NMOSD. For patients with suspected Brucellar myelitis secondary NMOSD, combination of immunosuppressant (such as rituximab) with antibiotics may be an effective individualized treatment.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
