Objective To evaluate the molluscicidal effect of spraying different formulations of niclosamide ethanolamine salt with drones against Oncomelania hupensis in ditches. Methods A semi-dry and semi-wet ditch with O. hupensis snails was selected in the second branch field of Jiangbei Farm, Jiangling County, Hubei Province in May 2023, and divided into 4 experimental areas, named groups A1, A2, B1 and B2. Environmental cleaning was performed in groups A1 and B2, and was not conducted in groups A2 or B2. Then, 50% wettable powder of niclosamide ethanolamine salt was sprayed with drones at an effective dose of 2 g/m2 in groups A1 and A2, and 5% niclosamide ethanolamine salt granule was sprayed with drones at an effective dose of 2 g/m2 in groups B1 and B2. O. hupensis snails were surveyed using the systematic sampling method 1, 3, 5, 7, 14 days after spraying, and the natural mortality and corrected mortality of O. hupensis snails were calculated. Results The occurrence of frames with living snails, mean density of living snails and natural mortality of snails were 97.50% (117/120), 6.30 snails/0.1 m2 and 1.18% (9/765) in the test ditch before spraying, respectively. There were significant differences in the mortality of snails among four groups 1, 3, 5, 7 and 14 days after spraying niclosamide formulations with drones (χ2 = 17.230, 51.707, 65.184, 204.050 and 34.435, all P values < 0.01). The overall mortality rates of snails were 94.51% (1 051/1 112), 79.44% (908/1 143), 96.54% (977/1 012) and 88.55% (1 021/1 153) in groups A1, A2, B1 and B2 (χ2 = 207.773, P < 0.05), respectively. In addition, there was no significant difference in the overall snail mortality between groups A1 and B1 (P > 0.05), and the snail mortality in groups A1 and B1 were both statistically different from that in groups A2 and B2 (all P values < 0.05). Conclusion Both 50% wettlable powder of niclosamide ethanolamine salt and 5% niclosamide ethanolamine salt granule sprayed with drones are active against O. hupensis snails in ditches, and environmental cleaning may improve the molluscicidal effect.

Objective:To study the clinicopathological features, immunohistochemical phenotypes, molecular changes, differential diagnosis and prognosis of isolated intraductal carcinoma of the prostate (iIDC-P).Methods:Three iIDC-P cases were collected retrospectively from 2016 to 2022 at Ningbo Clinical Pathology Diagnosis Center, Ningbo, China. The clinicopathologic features and immunophenotypic profiles were studied using light microscopy and immunohistochemistry. A targeted next-generation sequencing panel was used to analyze cancer-associated mutations. Follow-up and literature review were also performed.Results:The patients′ ages were 61, 67 and 77 years, and their preoperative prostate specific antigen (PSA) levels were 7.99, 7.99 and 4.86 μg/L, respectively. Case 1 and 2 were diagnosed on needle biopsy and radical prostatectomy (RP) specimens, and case 3 was diagnosed on a specimen of transurethral resection of the prostate (TURP). The RP specimen was entirely submitted for histologic examination. In the case 1, iIDC-P was found in one tissue core (involving two ducts) in the biopsy specimen, and in 6 sections (diameter, 0.3-1.1 cm) from the radical prostatectomy specimen, and one section had separate foci of low-grade acinar adenocarcinoma (diameter, 0.05 cm). In the case 2, 6 tissue sections from the biopsy specimens showed iIDC-P, and 13 sections from RP specimen showed iIDC-P (diameter, 0.5-1.6 cm), and the other 3 sections had separate low grade acinar adenocarcinoma (diameter, 0.6 cm). In the case 3, 5 tissue blocks from the TURP specimen showed iIDC-P. The case 1 and 2 showed solid architecture with expansile proliferation of neoplastic cells in native ducts and acini. The case 3 showed dense or loose cribriform pattern, with marked cytological atypia, and frequent mitotic figures. Comedonecrosis was found in solid or dense cribriform glands in the case 2. Immunohistochemically, surrounding basal cells were highlighted using high-molecular-weight cytokeratin (34βE12 and CK5/6) and p63, while P504s was positive in the tumor cells. The tumor cells were also positive for AR and prostate markers (NKX3.1, PSA and PSAP), and negative for GATA3. The iIDC-P and acinar adenocarcinoma both showed weak PTEN expression and no ERG (nuclear) expression. In case 2 and 3, targeted sequencing revealed activated oncogenic driver mutations in MAPK and PI3K pathway genes (KRAS, MTOR and PTEN). In addition, pathogenic mutation in TP53 and FOXA1 mutation were found in the case 2 and 3, respectively. No case demonstrated TMPRSS2::ERG translocation. All cases were microsatellite stable and had lower tumor mutation burdens (range, 2.1-3.1 muts/Mb). The patients showed no biochemical recurrence or metastasis after follow-up of 16-91 months.Conclusions:iIDC-P is a special type of intraductal carcinoma of the prostate and differs from intraductal carcinoma within high-grade prostate cancer. iIDC-P has unique molecular characteristics and may represent as a molecularly unique in situ tumor of prostate cancer.

Objective:To explore the potential correlation between cumulative pulse pressure (cumPP) level and metabolic syndrome (MetS), and to provide insights for MetS management.Methods:A total of 3 968 subjects who underwent health checkup were selected to form a research cohort, and the data were categorized into three groups based on the tertiles of cumPP levels. Cox proportional hazards regression model was employed to analyze the association between different cumPP levels and the incidence of new-onset MetS. Results:The risk of MetS increased with the increased tiers of the cumPP levels (2.5%, 4.3%, and 4.6%, Ptrend<0.001) during the median follow-up period of 2.16 years. Spearman rank correlation analysis showed that cumPP was positively correlated with waist circumference, systolic blood pressure, diastolic blood pressure and fasting plasma glucose (all P<0.05). The Cox proportional hazards regression adjusted model showed that the risk of MetS in Q2 and Q3 was higher than that in Q1 in the total population, and the same results were observed in males (all P<0.05), while there was no statistical significance in females. Model 3 of the total population adjusted for a variety of confounding factors displayed a higher risk of MetS in Q3 compared with that in Q1[1.654 (95% CI 1.272-2.151) ]. When stratified by sex, and the risk of MetS in Q3 was 1.665 times higher than that in Q1 (95% CI 1.245-2.227), while there was no statistically significant risk in female. According to the visual nomogram of independent risk factors screened by multivariate analysis based on Cox proportional hazards regression model, the incidence of MetS at 1 year, 2 years, and 3 years was 0.18%, 3.97% and 7.39%, respectively. In addition, the dose-response curve was plotted according to cumPP, suggesting that the risk of MetS gradually increased with the increase of cumPP in the total population. Subgroup analyses based on baseline systolic blood pressure levels showed that higher cumPP levels were associated with a higher risk of developing MetS, regardless of whether systolic blood pressure was abnormal. Conclusions:Elevated cumPP levels is significantly related to the incidence of new-onset MetS. Maintaining pulse pressure within an appropriate range over long term is crucial for the management of MetS.

To report the first case of cutaneous chronic active Epstein-Barr virus disease manifesting as persistent erythema multiforme in China. The 12-year-old female patient presented with recurrent erythema and blisters all over the body, accompanied by oral erosions for more than 5 months. Skin examination showed dark erythema scattered on the right upper eyelid and cheeks, as well as erosions and blisters arising in the dark erythema on the lower jaw; broad bean- to pigeon egg-sized blisters with clear fluids arising in erythema were scattered on the back, buttocks, and limbs, and some manifested as atypical targetoid lesions; there was a mung bean-sized erosion on the mucosa of the lower lip and the right buccal region each; the patient also presented with moon face and multiple striae atrophicae on the lower limbs. Histopathological examination of the skin lesions on the lower limb revealed basket-weave hyperkeratosis, epidermal necrosis, liquefaction degeneration of basal cells with subepidermal blister formation, and perivascular lymphocytic infiltration in the superficial dermis; direct immunofluorescence assay showed negative staining for IgG, IgM, IgA, and complement C3 among epidermal cells and at the basement membrane zone; enzyme-linked immunosorbent assay showed negative staining for serum antibodies against desmoglein 1/3 (Dsg1/3), BP180, and type Ⅶ collagen; immunohistochemical examination demonstrated partial positive staining for CD3, CD4, CD5, CD8, CD56, granzyme B, and Epstein-Barr virus-encoded RNA, positive staining for Ki67 (> 70%), but negative staining for CD20. The Epstein-Barr virus DNA level was measured to be 1.97 × 10 6 IU/ml in whole blood samples and 2.65 × 10 7 IU/ml in blister fluid samples. No mutation sites with functional significance were identified by whole-exome sequencing. Based on these findings, a diagnosis of cutaneous chronic active Epstein-Barr virus disease manifesting as persistent erythema multiforme was made. The patient was treated with methylprednisolone at a dose of 40 mg/d, intravenous drips of ganciclovir at 200 mg twice daily, etc., and discharged after improvement.

Objective:To analyze clinical, immunoserological, and therapeutic features of patients with anti-p200 pemphigoid.Methods:Clinical data were collected from patients with confirmed anti-p200 pemphigoid at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2015 to February 2024. Their clinical, immunoserological, and therapeutic characteristics were retrospectively analyzed.Results:A total of 35 patients were included, with a male-to-female ratio of 2.5∶1 (25 males and 10 females) and ages of 57.74 ± 17.12 years. Two (5.71%) patients were accompanied by psoriasis. In these patients, anti-p200 pemphigoid exhibited heterogeneous clinical phenotypes, mimicking classic bullous pemphigoid (20 cases, 57.14%), linear IgA bullous dermatosis (8 cases, 22.86%), or eczema (4 cases, 11.43%). The positive rates of direct immunofluorescence (DIF), indirect immunofluorescence on salt-split skin (ss-IIF), Western blot analysis with dermal extracts as substrates, and Western blot analysis with laminin γ1 C-terminal region (Lnγ1C) as substrates were 100% (24/24), 82.86% (29/35), 100% (35/35), and 80.64% (25/31), respectively. Among the 35 patients, treatment and follow-up information was available for analysis in 33. Six patients (18.18%) received non-glucocorticoid systemic therapy and topical glucocorticoid therapy, with a follow-up period ( M [ Q1, Q3]) of 19.50 (6.50, 69.25) months, and 1 withdrew the drugs. Sixteen patients received systemic glucocorticoids combined with traditional anti-inflammatory drugs, with a follow-up period of 13.50 (4.25, 18.00) months, the initial dose of glucocorticoids was equivalent to 0.30 - 0.50 mg·kg -1·d -1 of prednisone, and the time to disease control was 15.31 ± 5.23 days; among the 16 patients, 3 experienced fluctuations in disease condition which were alleviated by adding dapsone, and 1 discontinued glucocorticoids. Five patients (15.15%) received systemic glucocorticoids combined with immunosuppressants, with a follow-up period of 26.00 (14.00, 90.00) months, the initial dose of glucocorticoids was equivalent to 0.50 - 0.75 mg·kg -1·d -1 of prednisone, and the time to disease control was 10.20 ± 3.27 days; among the 5 patients, 2 received maintenance treatment with glucocorticoids (5 - 10 mg/d prednisone), 2 withdrew the drugs, and 1 relapsed after discontinuing glucocorticoids. One patient (3.03%) received systemic glucocorticoids combined with rituximab therapy, with a follow-up period of 53 months, and discontinued glucocorticoids thereafter. One patient (3.03%) received systemic glucocorticoids combined with dupilumab therapy, which proved to be effective. Four patients (12.12%) received systemic glucocorticoids combined with Janus kinase inhibitors, and 3 responded well. Conclusions:Anti-p200 pemphigoid presented a heterogeneous clinical profile in this series of patients, but scarring and milia were rare. Some patients showed negative results in Western blot analysis with Lnγ1C as substrates. The prognosis of anti-p200 pemphigoid was usually favorable, and most patients could achieve complete remission and ultimately discontinue medication.

Objective:To analyze clinical and immunoserological features of patients with epidermolysis bullosa acquisita (EBA) .Methods:Clinical data were collected from patients with confirmed EBA at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2017 to January 2022, and their clinical and immunoserological characteristics were retrospectively analyzed.Results:A total of 20 patients were collected, including 7 males and 13 females, and they were aged 41.85 ± 18.43 years. Ten patients presented with the classical phenotype of EBA, 8 with the inflammatory phenotype of EBA, and 2 with the mixed phenotype of EBA. Mucosal involvement occurred in 19 cases, nail involvement occurred in 4, scarring was observed in 9, and milia in 13. Indirect immunofluorescence on salt-split skin showed IgG deposition on the dermal side in 19 cases. Enzyme-linked immunosorbent assay for type Ⅶ collagen revealed positive results in 19 cases, with a diagnostic sensitivity of 95%. Western blot analysis with dermal extracts as substrates revealed a protein band with a relative molecular mass of 290 000 in 16 cases, with a diagnostic sensitivity of 80%, and multiple autoantibodies against different basement membrane zone antigens were identified in 3 cases. Fifteen patients received systemic glucocorticoids, including 2 receiving combined immunosuppressive agents and 13 receiving combined anti-inflammatory agents with dapsone and colchicine as the first and second commonly used anti-inflammatory agents respectively; among 5 patients receiving non-glucocorticoid therapy, 2 with inflammatory EBA were sensitive to dapsone and colchicine, while the other 3 patients were lost to follow-up. Totally, 17 patients were followed up for an average duration of 26.21 months. Among the 17 patients, 1 achieved complete remission off therapy, 2 achieved complete remission on minimal therapy, and the remaining 14 patients achieved partial remission.Conclusions:The treatment of EBA is challenging, and anti-inflammatory agents such as dapsone and colchicine are often used. Immunoserological tests are of great value in the diagnosis of EBA.

Purpose:
The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored.
Materials and Methods:
On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL).
Results:
A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse.
Conclusion
This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).
