Objective To explore the efficacy and safety of a zanubrutinib-based combination regimen as first-line treatment for patients with B-cell chronic lymphoproliferative disorder (B-CLPD). Methods A retrospective analysis was performed on 26 patients with B-CLPD, including indolent B-cell non-Hodgkin lymphoma (B-iNHL), mantle cell lymphoma (MCL), and other unclassifiable B-CLPD, who were newly diagnosed and treated at the Department of Hematology, Zhongshan Hospital (Xiamen), Fudan University between January 2021 and January 2025. Patients were divided into two groups according to the treatment regimen: BR (bendamustine plus rituximab) and ZBR (zanubrutinib combined with BR regimen). Baseline characteristics, treatment responses, and the incidence of treatment-related adverse events (TRAE) were compared between the two groups. Results No statistically significant differences in baseline characteristics were observed between the two groups. All patients completed at least four cycles of treatment. There were no significant differences between the BR and ZBR groups in partial response rate (46.2% vs 53.8%), complete response rate (53.8% vs 15.4%), overall response rate (100.0% vs 84.6%), or TRAE incidence. After the first cycle, the lymphocyte count was higher in the ZBR group than in the BR group (P＝0.002); no other statistically significant differences in other hematologic parameters were observed at any treatment cycle. Conclusions In patients with B-iNHL, MCL, and other unclassifiable B-CLPD, the ZBR regimen demonstrates similar safety and response rates to the BR regimen. These findings support further investigation into the clinical value of ZBR as first-line treatment regimen in a limited course for indolent lymphoid malignancies.

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.

Objective:To summarize the experience of designing hair transplantation for post-cleft lip repair moustache defects based on the morphological and tissue characteristics of the upper lip.Methods:A retrospective analysis was conducted on the clinical data of male patients treated at the Hair Transplantation Center of Plastic Surgery Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from January 2011 to July 2024. Based on the morphology and tissue texture of the upper lip after cleft lip repair, the position and shape of the moustache were designed. Hair follicles were harvested from the mid-occipital region and/or the jaw shadow area using either the strip harvesting method or the follicular unit excision (FUE) technique. Needles of 21 or 22 gauge were used to create incisions in the recipient sites down to the superficial subcutaneous layer. The hair shafts were clamped with micro-forceps and then transplanted into the recipient sites to restore the moustache shape. Postoperatively, the density, shape, direction of the moustache, and the condition of the donor site scars were observed and followed up.Results:A total of 47 male patients, aged 23-43 years (mean 28.7 years), were included. Among them, 29 had undergone lower triangular flap repair, 13 received the Millard technique, and 5 were treated with other surgical methods for cleft lip repair. For hair follicle extraction, the strip method was used in 7 cases, and FUE in 40 cases. The donor sites included the jaw shadow area (9 cases), mid-occipital region (23 cases), and a combination of both (15 cases). The number of transplanted follicular units ranged from 33 to 500 (mean 217). Follow-up duration ranged from 9 months to 10 years (mean 3.5 years). Postoperative complications included folliculitis in 6 cases, and 4 cases required additional transplantation due to insufficient density after one year. The remaining patients exhibited satisfactory hair growth, with natural mustache shape and direction. The graft survival rate was approximately 80%, and donor site scarring was minimal.Conclusion:When performing hair transplantation to treat post-cleft lip repair moustache defects, the design should prioritize the morphological and tissue characteristics of the upper lip, followed by consideration of overall position and bilateral symmetry of the moustache. Only by fully considering the characteristics of the recipient area can optimally repair outcomes be achieved.

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.

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.

Objective Discuss the safety and effectiveness of flow diverter device and traditional stent inthetreatment of unruptured ophthalmic segment aneurysms.Methods A retrospective analysis from January 2017 to January 2023 was performed on the clinical data of 70 cases of unruptured aneurysms in the Department of Neurosurgery of Southern Theater General Hospital treated with stent-assisted embolization.According to the type of implanted stents,theywere divided into flow diverter device group(n = 21)and traditional stent group(n = 49),and the postoperative clinical effects and complications of the two groups were compared.Results The two groups of patients followed 3 to 24 months,with an average of(14.4±1.82)months.The results of periopera-tive and follow-up showed that the inclusion rate was higher in the flow diverter device group and the traditional stent group(93.3%vs.87.9%),with no significant difference(P>0.05),and the incidence of perioperative and short-term complications was lower(0 vs.6.1%)in the flow diverter device group than in the traditional stent group,and there currencies rate in the flow diverter device group was lower than that in the traditional stent group(0 vs.6.1%),but the difference was not significant(P>0.05).Conclusion Flow diverter devices and traditional stents in the treatment of unruptured ophthalmic segment aneurysmsare feasible,safe and effective.Preliminary results suggest that the incidence of short-term complications and retreatment is lower after treatment with flow diverter devices,and the operation time is short,but further studies are needed to validate long-term complica-tions in patients.

Objective To explore the research status and future development trends of nursing case teaching at home and abroad,and to provide reference and guidance for the development of case teaching in nursing profession in China.Methods Data sources include the China National Knowledge Infrastructure(CNKI),Wanfang Data,and Web of Science databases.The CiteSpace software was used to visually analyze the research status and trends of nursing case teaching from January 2013 to Octo-ber 2023,covering nearly 11 years.Results A total of 2 889 valid articles were extracted.The important literature on nursing case teaching in China experienced a period of stable growth followed by rapid growth from 2013 to 2021.However,the number of publications and the number of publications in core journals on nursing case teaching abroad were higher than those in China.After 2021,both domestic and foreign publications on nursing case teaching showed a slow decline.The research on nursing case teaching in both domestic and foreign contexts is mainly conducted by universities,and the collaborative relationships between for-eign institutions and scholars are stronger than those within China.The research topics and hotspots in both domestic and foreign contexts are concentrated on the teaching applications for nursing students.Conclusion Nursing case teaching in China contin-ues to attract attention;however,compared to nursing case teaching abroad,the depth and breadth of research need to be further improved.Additionally,the collaboration between domestic authors and institutions is relatively limited.

Objective:To investigate the clinical, cytomorphology, immunocytochemical and molecular features of metastatic melanoma in serosal cavity effusion.Methods:Cytological specimens of 14 patients with melanoma in the chest and abdomen were collected from 2017 to 2023, at the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. SOX10, S-100 protein, PRAME, BRAF V600E, HMB45, and Melan A were detected by immunocytochemical methods. Fourteen cases were tested for routine antibody combinations, including Claudin4, HEG1, Calretinin, CD68, etc. Four of the patients had biopsy or surgical samples of metastatic solid lesions of primary sites, and further next-generation sequencing (NGS) or amplification refractory mutation system (ARMS)-PCR molecular test was performed. In addition, 30 cases of serosal effusion samples were collected as control groups (10 cases of benign mesothelial cell reactive hyperplasia, 10 cases of mesothelioma, and 10 cases of metastatic lung adenocarcinoma).Results:Among the 14 cases of melanoma, there were 7 males and 7 females, with ages ranging from 35 to 86 years, and an average age of 57 years, there 10 cases aged ≥50 years. The tumor cells in the serosal effusion varied in morphology and degree of atypia. SOX10 was positive in all 14 cases (14/14), S-100 protein was positive in 10 cases (10/14), PRAME was positive in 12 cases (12/14), BRAF V600E was positive in 10 cases (10/14), HMB45 was positive in 12 cases (12/14), and Melan A was positive in 13 cases (13/14). In 4 patients with histological correlation, the cytological and histological expression of SOX10, BRAF V600E, and PRAME was positive in all 4 cases (4/4); S-100 protein was positive in 2 cases (2/4); and HMB45 and Melan A were positive in 3 cases (3/4). Using NGS or ARMS-PCR, missense mutations of BRAF V600E were detected in all 4 patients; TERT promoter mutations was detected in 1 case; and CDKN2A terminating mutations and MSI1 deletion mutations were detected in the other case. SOX10, S-100, HMB45, Melan A, PRAME and BRAF V600E were all negative in 30 control samples of serosal cavity effusion.Conclusion:By observing the morphology of tumor cells, immunocytochemical test of several combination markers, especially the expression of SOX10, BRAF V600E and PRAME, can help to improve the positive diagnosis rate of melanoma in serous cavity effusion.

Objective:To summarize the experience of designing transplanted hair based on the orbital morphology and tissue characteristics for the treatment of eyebrow defects after burns.Methods:A retrospective analysis was conducted on clinical data of the patients with eyebrow defects after burns who treated at Hair Transplantation Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences between January 2011 and September 2023. The location and appearance of eyebrow were designed according to the orbital morphology and tissue characteristics. The follicles were extracted by incision of scalps strips and follicle unit excision (FUE) on the donor area of the occipital region near the posterior hairline or the posterior ear hairline. Scalps with scars that needed to be removed or had "dog ear" deformities following scalp expansion surgery that needed to be repaired were also be used as donor sites. The follicles were divided as follicle units (FUs) including single hair. The recipient area was punched with syringe needle of 22 or 22 G to subcutaneous superficial layer. Then the hair shaft was clamped with microforceps and the hairs were transplanted to the defective area to restore the appearance of eyebrow. The density, morphology, direction and scars of the donor sites were observed by following-ups.Results:A total of 197 patients with 282 eyebrows were recruited. There were 133 males and 64 females. The average age was 33.7 (9 to 62) years. There were 17 patients with skin graft transplantation in the eyebrow arch, 33 with flap and expanded flap repair, 36 with eyelid skin grafting, 111 with burn scar healing. A total of 51 patients had complete eyebrow defects on both sides, and 34 had partial defects. Sixty-five patients had complete eyebrow defects on single side, and 47 had partial defects. The amount of hair transplantation was from 53 to 600 FUs on 282 eyebrows. Seventy-five patients extracted follicles with incision of scalps strips and 122 with FUE. The patients were followed up for 9 months to 10 years. Folliculitis were found in 17 patients and completely cured by 75% alcohol disinfection. Nine patients with insufficient density underwent hair transplantation for a second time to increase the density of hairs one year later. And the implanted hairs grew well, which were similar to the shape and direction of normal eyebrows. Transplanted hairs of the rest patients grew well. The direction and appearance were satisfied. The scar in the donor site was not obvious.Conclusion:The transplanted hair should be designed primarily based on the orbital morphology and tissue characteristics for the treatment of eyebrow defects after burns. Then the position of the eyebrow and the bilateral symmetry should be considered. The ideal effect of eyebrow reconstruction would depend on the full consideration of the receipt site.
