Objective To preliminarily investigate the safety and efficacy of donor pancreas needle biopsy in simultaneous pancreas-kidney transplantation. Methods Clinical data of 7 cases undergoing donor pancreas biopsy were collected retrospectively. All cases underwent donor pancreas biopsy before or during simultaneous pancreas-kidney transplantation. Frozen section or paraffin sectioning techniques were used for tissue preparation, and hematoxylin-eosin and Masson staining were performed to histologically evaluate the donor pancreas. The quality of donor pancreas was comprehensively assessed by combining histological findings with the donor's clinical data. Postoperative follow-up data of 5 simultaneous pancreas-kidney transplant recipients were collected to summarize the safety of donor pancreas biopsy and the prognosis of transplant recipients. Results The 7 pancreas donors were aged 28 to 62 years, with a body mass index ranging from 20.76 to 27.68 kg/m2. Liver ultrasound indicated fatty liver in 3 cases, while pancreatic ultrasound did not reveal any significant abnormalities. Among them, biopsy was performed on 2 donors after completion of pancreatic procurement and processing, and the frozen section histology showed moderate acute pancreatitis changes (edema of acinar cells, necrosis and inflammatory cell infiltration). Combined with a serum amylase level elevated more than 3 times the upper limit of normal value, these two donor pancreases were finally discarded. The remaining 5 cases underwent biopsy immediately after pancreatic vascular anastomosis during simultaneous pancreas-kidney transplantation, and histological evaluation was performed on paraffin-embedded sections. No biopsy-related complications (such as bleeding, pancreatic fistula, etc.) occurred after transplantation. One recipient died of severe infection 2 months after transplantation, while the other 4 recipients were followed up for more than 5 years, with well-functioning transplant kidneys and pancreases. Conclusions Donor pancreas biopsy is relatively safe, and the risk of biopsy-related complications after transplantation is controllable. Comprehensive assessment of donor pancreas quality by combining histological evaluation with the donor's clinical indicators is conducive to improving the accuracy of donor pancreas selection and organ utilization.

ObjectiveTo investigate the mechanisms by which Liuwei Buqi prescription (LWBQ) regulates alveolar macrophage efferocytosis and improves inflammatory responses in rats with chronic obstructive pulmonary disease (COPD) characterized by lung-kidney Qi deficiency based on the nuclear factor erythroid 2-related factor 2 (Nrf2)/macrophage receptor with collagenous structure (MARCO) pathway. MethodsSuccessfully modeled rats were randomly divided into a model group, low-dose LWBQ group (LWBQ-L, 2.25 g·kg-1·d-1), medium-dose LWBQ group (LWBQ-M, 4.5 g·kg-1·d-1), high-dose LWBQ group (LWBQ-H, 9 g·kg-1·d-1), and aminophylline group (AMIN, 50 mg·kg-1·d-1), with 8 rats in each group. Another 8 healthy rats were included as the blank group. Except for the blank group, rats in the remaining groups were subjected to smoke exposure combined with forced swimming, intratracheal lipopolysaccharide (LPS) instillation, and subcutaneous hydrocortisone injection to establish a COPD model with lung-kidney Qi deficiency. After successful modeling, rats were administered different doses of LWBQ or AMIN by gavage. Body weight, fur condition, and oral secretions were observed. Pulmonary function was measured using an animal lung function analyzer. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of interferon-γ (IFN-γ), interleukin-6 (IL-6), interleukin-1 (IL-1), and tumor necrosis factor-α (TNF-α) in bronchoalveolar lavage fluid (BALF) and serum (SER). Hematoxylin-eosin (HE) staining was used to examine pathological changes in lung tissue. Giemsa staining was performed to detect eosinophils, basophils, and neutrophils in BALF. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) was used to detect apoptosis in lung tissue. Western blot and real-time polymerase chain reaction (Real-time PCR) were employed to determine the protein and mRNA expression levels of efferocytosis-related proteins growth arrest-specific gene 6 (GAS6), milk fat globule-epidermal growth factor 8 (MFG-E8), and pathway-related proteins Nrf2 and MARCO in lung tissue. ResultsCompared with the blank group, the model group showed reduced food intake, nasal and oral secretions with sputum, and decreased body weight (P<0.01), decreased peak expiratory flow (PEF) (P<0.01), increased forced vital capacity (FVC) (P<0.01), and decreased forced expiratory volume in 0.3 s/forced vital capacity [FEV0.3/FVC (%)] (P<0.01). The expression levels of IFN-γ, IL-6, IL-1, and TNF-α in BALF and SER were increased (P<0.01). Lung tissue exhibited structural destruction, hyperplasia, inflammatory exudation, increased apoptotic cells, and increased mean optical density (P<0.01). The protein and mRNA expression levels of GAS6, MFG-E8, and MARCO, as well as Nrf2 mRNA expression, were increased (P<0.01). Compared with the model group, the LWBQ groups showed increased food intake, reduced nasal and oral secretions with sputum, and increased body weight (P<0.05, P<0.01). PEF was increased (P<0.01). FVC was increased in rats treated with low- and medium-dose LWBQ (P<0.01), and FEV0.3/FVC (%) was increased in rats treated with medium- and high-dose LWBQ (P<0.05, P<0.01). The expression levels of IFN-γ, IL-6, IL-1, and TNF-α in BALF and SER were decreased (P<0.01). Lung tissue structure was relatively intact, with improvement in hyperplasia and inflammatory exudation. The number of apoptotic cells in lung tissue was reduced, and mean optical density was decreased (P<0.05, P<0.01). The protein and mRNA expression levels of efferocytosis-related proteins GAS6 and MFG-E8 and pathway-related proteins Nrf2 and MARCO were increased (P<0.01). ConclusionLWBQ can alleviate pulmonary and systemic inflammation, improve lung function, and reduce lung tissue damage in rats with COPD characterized by lung-kidney Qi deficiency. The mechanism may be related to enhancement of alveolar macrophage efferocytosis through regulation of the Nrf2/MARCO pathway.
3.Longitudinal cohort study on pubertal development trajectories of testicular and breast development among children
Chinese Journal of School Health 2026;47(3):408-412
Objective:
To characterize longitudinal trajectories of testicular development in boys and breast development in girls, so as to provide reference data for understanding patterns of pubertal sexual maturation.
Methods:
Based on the Shanghai Pudong New Area Cohort Study on Growth, Development and Health in Children and Adolescents, a baseline survey was conducted in 2020 using a mult stage cluster random sampling method. A total of 2 184 children who completed all follow ups during the primary school period from 13 elementary schools in Pudong New Area,Shanghai,with annual follow ups during 2021-2025. Testicular volume and Tanner stage of breast development were assessed by professional physicians using standardized visual inspection and palpation. The age distribution of testicular volume and breast development was fitted by using cumulative link mixed models and Turnbull s nonparametric maximum likelihood estimation method.
Results:
Median ages for testicular volumes of 2, 3, 4 and 5 mL in boys were 7.07, 9.24, 10.29, and 11.57 years old, respectively. Median ages for Tanner breast stages Ⅱ, Ⅲ, Ⅳ, and Ⅴ in girls were 8.55 , 10.17, 11.18, and 13.78 years old, respectively. Based on overweight and obesity, stratified analysis showed that earlier pubertal onset among overweight/obesity children, and the key milestones for pubertal initiation were testicular volume reaching 4 mL in boys and breast Tanner II in girls for 10.29, 10.83; 8.18, 9.00 years.
Conclusion
Overweight and obesity are associated with earlier pubertal initiation,but there are certain gender and developmental stage specific patterns.

OBJECTIVE:
To summarize the clinical features and management of two brothers affected with X-linked inhibitor of apoptosis protein (XIAP) deficiency.
METHODS:
This study retrospectively analyzed the clinical presentations, treatment, and follow-up of two brothers with XIAP deficiency diagnosed at Shanghai Children's Hospital in 2020, and summarized similar cases recorded in databases such as PubMed, Wanfang, Chinese Medical Association Journals, and WIP from January 2006 to November 2024. This study was approved by the Medical Ethics Committee of our hospital (Ethics No.: 2025R128-E01).
RESULTS:
Patient 1 was the younger brother, who presented at 8 years of age with growth retardation, folliculitis, erythema nodosum, and perineal abscess. Sequencing revealed that he has carried a hemizygous c.566T>C (p.Leu189Pro) variant of the XIAP gene, which was inherited from his mother. He was allergic to infliximab treatment and underwent allogeneic stem cell transplantation (HSCT) in January 2021. During a follow-up of 3 years and 10 months post-transplantation, he showed no gastrointestinal symptoms and had a good outcome. Patient 2 was the elder brother, who presented at 10 years and 6 months of age with growth retardation, rash, and anal fistula. Genetic testing revealed the same variant. He was treated with oral azathioprine but did not have regular follow-ups. At 14-years-and-6-months of age, he had developed severe gastrointestinal infection and hemophagocytic lymphohistiocytosis, which was alleviated after treatment with antibiotics, glucocorticoids, immunoglobulin, and rituximab. He is currently being prepared for HSCT. A total of 13 publications were retrieved, which involved 64 patients from 23 families, with 23 different variants identified. The main clinical manifestations included splenomegaly (34 cases, 53.1%), hemophagocytic lymphohistiocytosis (27 cases, 42.2%), and inflammatory bowel disease or colitis (20 cases, 31.8%). There were significant phenotypic differences among patients from the same family. Thirteen patients (20.3%) underwent HSCT, with a survival rate of 61.5%.
CONCLUSION
For male children with early onset, poor treatment response, especially those with unexplained splenomegaly and IBD-like symptoms, early genetic testing is recommended. HSCT is a safe and effective treatment for XIAP deficiency. For patients with developmental delay, early onset, and severe IBD phenotype, early transplantation is recommended.

ObjectiveTo explore the potential mechanism of moxibustion at Guanyuan (CV 4) in delaying skin photoaging. MethodsThirty-two male Wistar rats were randomly divided into four groups, namely blank group, model group, vitamin E group, and moxibustion group, with 8 rats in each group. Except for the blank group, dorsal skin of rats were exposed to ultraviolet (UV) radiation to establish a skin photoaging model. One week after modeling, the moxibustion group received moxibustion at "Guanyuan (CV 4)" once a day, five days per week; the vitamin E group received vitamin E (25 mg/kg·d) once a day by gavage, five days per week; the blank group, model group, and moxibustion group received an equivalent volume of normal saline via gavage; the intervention lasted for 7 weeks. After 7 weeks, dorsal skin tissues were collected to analyze the following indicators, such as skin tissue moisture content, histomorphological changes using hematoxylin-eosin (HE) staining, Collagen Ⅰ and collagen Ⅲ content using ELISA. Malondialdehyde (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), hydrogen peroxide (H2O2), and catalase (CAT) activity in skin tissue were dectected. Western Blot was used to determin autophagy-related proteins, including microtubule-associated protein 1A/1B-light chain 3 (LC3), polyubiquitin-binding protein (p62), and autophagy-specific gene (Beclin-1); LC3, p62, and Beclin-1 mRNA expression was detected via qRT-PCR, and autophagosome formation was observed using transmission electron microscopy (TEM). ResultsHE staining showed that the epidermal structure in the blank group was orderly and evenly thick, while the model group exhibited uneven epidermal thickness. In the moxibustion group, the epidermis was well-structured, smooth, and uniform, with densely arranged dermal layers; the epidermis in the vitamin E group was thicker than that in the model group. Compared with the blank group, the model group exhibited decreased skin moisture content and reduced level of Collagen Ⅰ and collagen Ⅲ, reduced SOD, CAT, and GSH-Px activity in skin tissue, increased H2O2 and MDA activity, elevated p62 protein and mRNA expression, reduced LC3 and Beclin-1 protein and mRNA expression (P<0.05 or P<0.01). Compared with the model group, the moxibustion group showed significant improvement in all these indicators (P<0.05 or P<0.01); whereas the vitamin E group did not show a statistically significant difference in Collagen Ⅰ and collagen Ⅲ levels (P>0.05). TEM results showed that, compared with the blank group, the model group had atrophic skin cells, extensive mitochondrial vacuolization, and degraded cellular structures; the moxibustion group exhibited crescent- or cup-shaped autophagosomes with a significantly increased number of autophagosomes per unit area, whereas the vitamin E group showed less improvement than the moxibustion group. ConclusionMoxibustion at "Guanyuan (CV 4)" may alleviate skin photoaging by regulating oxidative stress imba-lance, modulating cellular autophagy, and promoting collagen synthesis, thereby slowing the aging process of the skin.
