AIM: To evaluate the safety and efficacy of low-dose transscleral cyclophotocoagulation(TSCP)in the management of persistent ocular hypertension after an acute attack of angle-closure glaucoma(AACG).METHODS:This retrospective study enrolled patients diagnosed with persistent ocular hypertension after an acute AACG attack at the No.988 Hospital of the Joint Logistics Support Force of the Chinese PLA between September 2023 and September 2024. All patients underwent low-dose TSCP using a semiconductor diode laser. Subsequent cataract surgery combined with goniosynechialysis was performed once intraocular pressure(IOP)was stabilized. Changes in anterior chamber depth(ACD), best-corrected visual acuity(VA), and IOP were compared before and after TSCP, as well as before and after phacoemulsification. Post-TSCP complications were also documented.RESULTS: A total of 21 patients(21 eyes)were enrolled, including 8 males and 13 females, with a mean age of 67.95±7.25 y. Compared with pre-cyclophotocoagulation values, ACD increased significantly at 3 d post-TSCP(1.49±0.18 vs 1.22±0.21 mm; P<0.001). BCVA and IOP decreased significantly at 1 d post-TSCP, pre-phacoemulsification, 1 wk post-phacoemulsification, and 1 mo post-phacoemulsification compared with pre-TSCP IOP(all P<0.01). Regarding postoperative complications, 2 eyes experienced pain on the day of the procedure, 5 eyes developed mild corneal endothelial folds, 2 eyes exhibited moderate anterior chamber inflammatory reaction, and 12 eyes showed shallow ciliary body detachment. No serious complications occurred during the 1-month follow-up period.CONCLUSION:Low-dose TSCP appears to be an effective bridging therapy for patients with persistent ocular hypertension following an AACG attack. It facilitates rapid IOP reduction, alleviates symptoms, and helps preserve visual function with a favorable safety profile, thereby reducing the risks associated with subsequent intraocular surgery.

Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated chronic fibroinflammatory disease first recognized in the beginning of the 21st century, affecting nearly all organs throughout the body. After over two decades of exploration, significant progress has been made in the epidemiology, etiology and pathogenesis, clinical spectrum and classification, and treatment strategies for this disease. From the initial conceptual integration that consolidated multiple previously isolated conditions into a unified category, to the in-depth analysis of the roles of immune cell subsets, and further to the implementation of high-level evidence-based clinical trials for B-cell-targeting therapies, the research history of IgG4-RD exemplifies modern medicine′s continuously deepening understanding of complex and "new" diseases. This article aims to review the core advances in the field of IgG4-RD and discuss future research directions, to provide a reference for both basic research and clinical diagnosis and treatment.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a patient with Weiss-Kruszka syndrome (WSKA). METHODS: A male patient presented with primary infertility for 1 year post-marriage, intellectual disability, and blepharoptosis at Huzhou Maternity and Child Health Care Hospital from October to December 2024 was selected as the study subject. Peripheral blood samples were collected from the patient and his family members. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. This study was approved by the Ethics Committee of the Hospital (Ethics No. 2023-R-010). RESULTS: The patient, a 29-year-old male, had exhibited short stature, trigonocephaly, bilateral blepharoptosis, arched eyebrows, brachydactyly, redundant skin folds, webbed neck, hypertrichosis, mild intellectual disability, and speech impairment. WES revealed that he has harbored a de novo heterozygous frameshifting variant of the ZNF462 gene, namely c.945_946del (p.T316Rfs*42). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PM2_Supporting+PVS1+PM6_Supporting). CONCLUSION The ZNF462 c.945_946del variant probably underlay the WSKA in this patient. Above finding has enriched the mutational spectrum of the ZNF462 gene.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objectives:To investigate the physical growth status of pediatric patients with transfusion-dependent thalassemia (TDT) and analyze the effects of treatment-related and socioeconomic factors on physical growth.Methods:Based on the specialized thalassemia database from gene therapy clinical research at the Institute of Hematology & Hospital of Blood Diseases, Chinese Academy of Medical Sciences & Peking Union Medical College, we collected data on height and weight development, family economic status, and medical records of 338 pediatric patients with TDT from October 2023 to May 2024. The length/height-for-age and body mass index (BMI) -for-age were classified based on the Growth Standard for Children under 7 Years of Age, Standard for Height Level Classification among Children and Adolescents Aged 7-18 Years, and Dietary Guidelines for Chinese Residents. Logistic regression analysis was conducted to assess the effects of family economic status and disease-related treatment on length/height-for-age and BMI-for-age.Results:Among the 338 patients, 118 were children and 220 were adolescents (192 males and 146 females), with a median age of 12 years (range: 0.8-18) and a median diagnosis duration of 10.3 years (range: 0.5-17.9). Subtypes included α-thalassemia [21 cases (6.2%) ], β-thalassemia [288 cases (85.2%) ], and combined αβ-thalassemia[29 cases (8.6%) ]. The monthly household income of patients was concentrated in 3 000-5 000 yuan (39.9%) and 5 001-10 000 yuan (34.9%), whereas 67.2% of the families had monthly medical expenses of <3 000 yuan. Of the patients, 75.5% received their first transfusion before 1 year of age. The proportions of children and adolescents with pretransfusion hemoglobin (HGB) of ≤70 g/L were 4.2% and 6.4%, respectively. Adolescents demonstrated significantly higher rates of transfusion frequency of <4 weeks/session, monthly red blood cell infusion of >2 U, serum ferritin (SF) of ≥5 000 μg/L, iron chelation therapy, and splenectomy compared with children (all P<0.05). Of the 338 patients, 26.0%, 22.8%, and 8.9% demonstrated stunted growth, underweight, and concurrent stunted growth with underweight, respectively. No significant difference was observed in the stunted growth rates between children (22.9%) and adolescents (27.7%) ( P=0.402). However, the underweight rate in adolescents (26.8%) was significantly higher than that in children (15.3%) ( P=0.023). The multivariate analysis determined the following risk factors for stunted growth: monthly household income of <10 000 yuan (5 001-10 000 yuan: OR=5.49, 95% CI: 1.48-35.76; 3 000-5 000 yuan: OR=6.87, 95% CI: 1.88-44.60; <3 000 yuan: OR=9.29, 95% CI: 2.20-64.77), pretransfusion HGB of ≤70 g/L ( OR=3.25, 95% CI: 1.07-10.18), and SF of ≥5 000 μg/L ( OR = 3.04, 95% CI: 1.20-7.70). Longer diagnostic duration was associated with underweight ( OR=1.10, 95% CI: 1.01-1.20) . Conclusions:Children and adolescents with TDT with pretransfusion SF of ≥5 000 μg/L, HGB of ≤70 g/L, low monthly household income, or longer diagnosis duration were significantly more likely to experience delayed physical growth.

Objective:To analyze the infection status of HBV among the healthy population in Tongchuan city in 2023, and compare it against the data from 2006, 2014, and 2020, thereby elucidating epidemiological trends and providing reference for optimizing hepatitis B prevention and control strategies in Tongchuan city.Methods:By using the method of multi-stage stratified random sampling, healthy people aged 1-59 from eight villages/communities in the four districts and counties of Tongchuan city were selected for on-site investigation and blood sample collection. ELISA was used to detect the five hepatitis B markers of the survey respondents, including HBsAg and HBsAb, and the seroprevalence rates of the populations with different characteristics were analyzed. Statistical analysis was performed using Chi-square test.Results:In 2023, a total of 1 926 healthy people were surveyed. After standardization, the positive rates of HBsAg, HBsAb, and HBV, and the rate of all five hepatitis B markers being negative were 0.56%, 54.57%, 26.77%, and 33.05%, respectively. Children aged 1-4 had the lowest positive rates of HBsAg, HBcAb, HBeAb, and HBV, as well as the lowest rate of all five hepatitis B markers being negative, while they had the highest positive rate of HBsAb. In the population aged 1-29, the positive rates of HBsAg and HBV, and the rate of all five hepatitis B markers being negative showed an upward trend with increasing age, while the positive rate of HBsAb showed a downward trend. In particular, the positive rate of HBsAb dropped sharply in the 5-14 age group. In 2023, the positive rate of HBV in the population aged 1-29 was 10.93% (111/1 016), and the rate of all five hepatitis B markers being negative was 38.39% (390/1 016), both lower than the results of the previous three surveys. The positive rate of HBsAb was 56.69% (576/1 016) in people aged 1-29 in 2023, which was higher than the results of the previous three surveys.Conclusions:Although certain achievements have been made in the prevention and control of hepatitis B in Tongchuan city in 2023, with more than one-third of the population showing all negative results in the five hepatitis B tests, the positive rate of HBsAb in the 5-14 age group has dropped sharply. Further actions required for hepatitis B prevention and control in Tongchuan city include optimizing the childhood immunization schedule for national immunization program vaccines, implementing booster programs for adolescents, and developing tailored immunization strategies for adults.

Objective:To investigate the efficacy and safety of trastuzumab deruxtecan (T-DXd) in the treatment of metastatic breast cancer.Methods:A retrospective case series study was conducted. The clinical data of 38 breast cancer patients with metastasis in other parts who received T-DXd treatment in Xi'an International Medical Center Hospital from August 2021 to August 2024 were analyzed. The clinical efficacy and incidence of adverse reactions in patients were recorded, comparison of clinical efficacy in stratified patients based on clinical characteristics was performed, and the progression-free survival (PFS) was analyzed using Kaplan-Meier method.Results:All 38 patients were female, with a median age [ M ( Q1, Q3)] of 55 (42, 60) years; according to the guidelines of the American Society of Clinical Oncology/College of American Pathologists, 13 cases (34.2%) were positive for human epidermal growth factor receptor 2 (HER2) and 25 cases (65.8%) were low in HER2 expression; the Eastern Cooperative Oncology Group (ECOG) physical status scores of 23 cases (60.5%) were 0-2 points and 15 cases (39.5%) were 3-4 points; the median number of T-DXd treatment lines was 4 (2,16) lines. According to the Response Evaluation Criteria in Solid Tumors 1.1, the objective response rate (ORR) of T-DXd treatment was 34.2% (13/38), and the disease control rate (DCR) was 78.9% (30/38); the ORR of patients aged ≤ 50 years old was higher than that of patients aged >50 years old [56.3% (9/16) vs. 18.2% (4/22)], patients with HER2 positive was lower than that of patients with low HER2 expression [100.0 (13/13) vs. 68.0% (17/25)], patients with previous tyrosine kinase inhibitor (TKI) treatment was higher than that of patients without TKI treatment [100.0% (12/12) vs. 69.2% (18/26)], and the DCR of patients with T-DXd treatment for ≥ 4 cycles was higher than that of patients with T-DXd treatment for 1-3 cycles [100.0% (25/25) vs. 38.5% (5/13)], and the differences were statistically significant (all P < 0.05). Among the 38 patients, 19 (50.0%) stopped medication due to disease progression, 11 (28.9%) stopped medication due to economic reasons, 1 (0.8%) stopped medication due to grade 3 nausea and vomiting, and 1 (0.8%) stopped medication due to grade 2 interstitial lung disease (ILD), while the remaining 6 (15.8%) were undergoing T-DXd treatment. The median follow-up time was 9.5 (3.9, 17.8) months, and 16 cases (42.1%) progressed and died; the median PFS time was 5.9 months (95% CI: 3.1-8.7 months). Adverse reactions were mostly grade 1-2; common hematological adverse reactions included leukopenia [18 cases (47.3%)], neutropenia [16 cases (42.1%)], thrombocytopenia [11 cases (28.9%)], and anemia [15 cases (39.5%)]. Non-hematological adverse reactions included nausea [28 cases (73.7%)], vomiting [15 cases (39.5%)], decreased appetite [20 cases (52.6%)], fatigue [22 cases (57.9%)], alopecia [22 cases (57.5%)], elevated aspartate aminotransferase [20 cases (52.6%)], and elevated alanine aminotransferase [15 cases (39.5%)] were more common. Two cases developed interstitial lung disease (ILD), classified as grade 1 and grade 2, respectively. After discontinuation of medication and treatment with methylprednisolone, they returned to normal. Conclusions:T-DXd ≥ 2 line therapy has good efficacy and safety in the treatment of HER2 positive or low expression metastatic breast cancer. Bone marrow suppression and gastrointestinal adverse reactions are the most common, and the occurrence of ILD should be noted in the treatment.

Objective:To investigate the short-term efficacy and safety of rituximab (RTX) in children with calcineurin inhibitor (CNI) resistant steroid resistant nephrotic syndrome (SRNS).Methods:A retrospective case analysis was conducted. Thirteen children with CNI resistant SRNS who were regularly treated with RTX (375 mg/m 2 per dose (maximum dose 500 mg), 1 dose per week, a total of 4 doses) in Department of Nephrology, Children′s Hospital of Fudan University from January 2016 to December 2023 were enrolled. The general data, disease related information, urinary protein/creatinine, serum albumin, blood creatinine before RTX treatment, immunosuppressants, adverse events, and monthly urinary protein/creatinine, serum albumin, and blood creatinine indexes within 6 months after RTX treatment were collected. The changes of urinary protein/creatinine, serum albumin and estimated glomerular filtration rate (eGFR) before and after RTX at 3 and 6 months were analyzed by using paired sample t test and Wilcoxon signed-rank test. Results:Among the 13 patients, 8 were male and 5 were female. The age of disease onset was 4.0 (2.9, 6.8) years and the age of RTX treatment was 9.8 (5.9, 13.6) years. There were 8 cases of focal segmental glomerulosclerosis, 3 cases of minimal change disease and 2 cases of mesangial proliferative glomerulonephritis. No clinically significant gene variation was detected in 12 cases and the other one did not receive gene test. Before RTX treatment, 11 cases were in chronic kidney disease stage G1, and 1 case each was in stage G2 and stage G3. Ten children completed 4 doses of RTX treatment, 1 patient completed 3 doses, and 2 patients completed 2 doses. Urinary protein/creatinine in 13 children at 3 and 6 months after RTX treatment was significantly lower than baseline (0.60 (0.13, 2.04), 0.49 (0.28, 1.10) vs. 1.44 (0.76, 4.11) mg/mg, Z=-2.34, -2.34, both P<0.05), and serum albumin was significantly higher than baseline ((35±8), (34±7) vs. (30±6) g/L, t=2.30, 2.60, both P<0.05). The eGFR at 6 months after RTX treatment was not significantly different from the baseline ((110±32) vs. (113±35) ml/(min·1.73 m 2), t=-0.76, P>0.05)). No serious adverse reactions occurred in this study. Conclusion:RTX could reduce urinary protein and increase serum albumin in short-term treatment in children with CNI resistant SRNS without significant side effects.
