To analyze the clinical and genetic features of oculopharyngodistal myopathy (OPDM) patients and compare the phenotypic differences among various causative genes. A total of 65 genetically confirmed OPDM patients from 43 unrelated families, who were admitted to the Department of Neurology, Peking University First Hospital between January 2008 and December 2025, were retrospectively included.The general demographic data, clinical manifestations, laboratory/auxiliary examinations, muscle pathology, and genetic test results were systematically collected and analyzed. The clinical and pathological characteristics among different OPDM subtypes were compared. Among the 65 patients(39 male and 26 female), the mean age of onset was (31.20±10.43) years (range: 14 to 63 years). The initial symptom was predominantly distal limb weakness (67.44%), which gradually progressed to involve the extraocular muscles, pharyngeal muscles, facial muscles and proximal limb muscles. Serum creatine kinase levels were mildly to moderately elevated. Muscle pathological examinations revealed rimmed vacuoles and intranuclear inclusions (within muscle fibers). The mean duration from onset to diagnosis was (12.33±7.88) years (range: 1 to 32 years). All probands had negative results on conventional next-generation whole-exome sequencing; pathogenic variants were identified through third-generation long-read sequencing or OPDM-targeted repeat-primed polymerase chain reaction(RP-PCR). Among the 43 families, OPDM2 subtype was the most common genetic subtype ( OPDM2 was the predominant subtype in this study. All subtypes share similar age of onset and muscular pathological changes, yet exhibit distinct disease progression patterns. Future multicenter prospective cohort studies are warranted to further elucidate the clinical characteristics, pathogenetic mechanisms, and prognostic differences among OPDM subtypes.

ObjectiveTo investigate the role of the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway in intestinal mucosal barrier damage in ulcerative colitis, as well as the intervention mechanism of Shaoyaotang. MethodsSixty SD rats were allocated into a blank group, a model group, a mesalazine (0.42 g·kg-1) group, and low-, medium-, and high-dose (11.1, 22.2, 44.4 g·kg-1, respectively) Shaoyaotang groups. A model of ulcerative colitis was induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS). After successful modeling, rats were administrated with corresponding agents via gavage for 7 days. Changes in colon length and colon weight were observed. Hematoxylin-eosin staining was performed to examine the pathological changes of the colon, and immunohistochemistry was employed to detect the expression of the inflammatory cytokine interleukin-8 (IL-8), cyclooxygenase-2 (COX-2), junction adhesion molecule-1 (JAM-1), and claudin-1 in the colon. Western blot analysis was performed to determine the protein levels of TLR4, MyD88, and NF-κB in the colon. ResultsCompared with the blank group, the model group showed elevated DAI score (P<0.01), reduced colon length and colon weight (P<0.01), down-regulated protein levels of JAM-1 and claudin-1 (P<0.01), and up-regulated protein levels of IL-8, COX-2, TLR4, MyD88, and NF-κB p65 (P<0.01) in the colon tissue. Compared with the model group, each treatment group showed decreased DAI score (P<0.05, P<0.01), increased colon length and colon weight (P<0.05, P<0.01), up-regulated protein levels of JAM-1 and claudin-1 (P<0.01), and down-regulated protein levels of IL-8, COX-2, TLR4, MyD88, and NF-κB p65 (P<0.01) in the colon tissue. ConclusionShaoyaotang alleviates intestinal inflammation and intestinal mucosal damage to protect intestinal barrier integrity by regulating the TLR4/MyD88/NF-κB signaling pathway.

With the rising incidence of colon cancer, several studies have indicated that aquaporin 1 (AQP1) expression is associated with the development of colon cancer. This study aims to elucidate the potential molecular mechanisms between them. Methods: We screened data from The Cancer Genome Atlas (TCGA) database and retrospectively examined AQP1 protein expression in 127 colon cancer patients to analyze the relationship between AQP1 expression and pathological stages, prognosis. We created stable colon cancer cell lines with differential AQP1 expression, the effect of AQP1 expression on the proliferation and migration of colon cancer cells was assessed by in vitro and in vivo studies, and explored potential molecular mechanisms through Western blotting. Results: High AQP1 expression was associated with poorer survival (overall survival [OS], p = .028) in colon cancer patients from the TCGA database. Similarly, retrospective clinical data indicated that high AQP1 expression was associated with reduced disease-free survival and OS (p = .036 and p = .017, respectively). The low-expressing AQP1 colon cancer cells exhibited a decrease in proliferation and migration ability of colon cancer cells compared to the overexpressing AQP1 group (p < .05) in vitro and in vivo. Immunohistochemistry and western blotting experiments validated heightened expression of N-cadherin, vimentin, and claudin- 1 in the tumor tissues of the overexpressing AQP1 group. Conversely, reduced AQP1 expression resulted in decreased expression of claudin- 1. Conclusions: AQP1 correlates with unfavorable prognosis in colon cancer and potentially enhances the proliferation and migration of colon cancer by up-regulating claudin-1 expression.

Aortic dissection is a serious cardiovascular disease characterized by acute onset and high mortality rates. Although advancements in surgical techniques and anesthesia methods have significantly reduced surgical mortality, postoperative complications, particularly pulmonary complications, remain a challenge for the recovery of patients with aortic dissection. Existing studies indicate that respiratory rehabilitation plays a crucial role in preventing and alleviating postoperative pulmonary complications, and its application is gradually expanding. However, current understanding of respiratory rehabilitation treatment for patients with aortic dissection is still insufficient, and there is a lack of standardized protocols in clinical practice. This article aims to review the existing research evidence, comprehensively analyze common pulmonary complications after aortic dissection surgery, their pathogenesis, the latest advancements in perioperative respiratory rehabilitation, and the main challenges faced, in order to provide references for clinical practice and future research.

To systematically synthesize existing literature, identify the core competency elements essential for instructors to effectively deliver pediatric simulation-based teaching, and provide evidence-based references for faculty development and evaluation. A systematic review was conducted by searching PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Data Knowledge Service Platform from database inception to January 31, 2026. Two researchers independently performed literature screening and data extraction according to predefined inclusion and exclusion criteria. Methodological quality was assessed using the mixed methods appraisal tool (MMAT). Thematic synthesis wasemployed to code, summarize, and integrate the included literature. A total of 14 studies published between 2019 and 2026 were included, comprising 7 from China, 3 from the United States, and 1 each from Turkey, Japan, India, and Canada. In terms of study design, there were 3 randomized controlled trials, 4 quasi-experimental studies, 1 qualitative study, 2 cross-sectional surveys, 3 non-randomized controlled trials, and 1 mixed-methods study. Five studies received an MMAT score of 100%, while 9 scored 80%, indicating an overall moderate-to-high methodological quality. A total of 87 initial codes were extracted, which were compared and consolidated into 25 subclusters and 8 descriptive themes, ultimately abstracted into 4 analytical themes (i.e., four core competency domains): curriculum design and development; instructional facilitation and feedback; technical proficiency and scenario management; and assessment, reflection, and continuous professional development. The four-core-competency framework identified in this study encompasses the complete teaching chain from pre-session preparation and in-session implementation to post-session evaluation and improvement, and may serve as a reference for the selection, training, assessment, and career development of pediatric simulation educators.

To identify clinical outcome of treatment and influencing factors of prognosis of extremely low birth weight infants(ELBWI). Clinical data of ELBWI admitted to the neonatal intensive care unit of Peking Union Medical College Hospital during the study period(from January, 2010 to December, 2024) were retrospectively collected, and their in-hospital outcomes were recorded. Infants who received active treatment were enrolled in active treatment group, while those who were given up treatment due to family reasons in the absence of severe complications were enrolled in treatment-withdrawal group. According to gestational age, the active treatment group was further subdivided into four subgroups: 23-25+6 weeks, 26-27+6 weeks, 28-29+6 weeks, and ≥30 weeks. Based on year of birth, infants were divided into 2010—2019 group and 2020—2024 group. The Aalen-Johansen competing risk model was used to estimate the cumulative incidence of severe complications. Multivariate Logistic regression analysis was performed to identify independent risk factors for mortality. Cox proportional hazards regression model was used to analyze factors associated with survival without major complications. A total of 151 ELBWI were enrolled, including 79 males(52.3%) and 72 females(47.7%). The median gestational age was 27.4(26.4, 29.0) weeks, and the median birth weight was 840(750, 930) g. There were 14 cases(9.3%, 14/151) in treatment-withdrawal group, 137 cases(90.7%, 137/151) in the active treatment group. In the active treatment group, 16 infants(11.7%, 16/137) died or were withdrawn from treatment due to severe complications, and 121 infants(88.3%, 121/137) survived at discharge. The survival rates of rescue by gestational age subgroups were as follows: 75.0%(21/28) in the 23-25+6 weeks group, 90.9%(40/44) in the 26-27+6 weeks group, 93.6%(44/47) in the 28-29+6 weeks group, and 88.9%(16/18) in the ≥30 weeks group. Among the 137 actively treated infants, the incidences of moderate-to-severe bronchopulmonary dysplasia(BPD), sepsis, severe retinopathy of prematurity, severe intraventricular hemorrhage(IVH), severe necrotizing enterocolitis, and periventricular leukomalacia were 60.6%(83/137), 30.7%(42/137), 12.4%(17/137), 13.1%(18/137), 8.8%(12/137), and 1.5%(2/137), respectively. Compared with the 2010—2019 group, the 2020—2024 group had a higher rate of survival without major complications, a shorter time to full enteral feeding, and a lower incidence of moderate-to-severe BPD( Gestational age is an independent predictor of prognosis in ELBWI. A comprehensive manage-ment strategy oriented toward "improving quality of survival" should be implemented to maximize the quality of survival while ensuring the survival rate of ELBWI.

OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years, and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information, medication- related problems, and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included, among which females aged 20-39 years accounted for the highest proportion (66.04%); obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally, 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved, including 538 cases of drug consultations (52.28%), 453 medication recommendations (44.02%), 22 medication restructuring(2.14%), and 16 medication education (1.55%); the most common types of medication-related problems identified were adverse drug events(70.07%). CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients, challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction, enhancing pharmacist training, and establishing various forms of outpatient pharmaceutical service models.

Objective:To explore the clinical features and genetic characteristics of three patients with Infantile liver failure syndrome type 2 (ILFS2).Methods:Three children who were diagnosed with ILFS2 at the Children′s Hospital Affiliated to Zhengzhou University from February 2023 to February 2024 were selected as the study subjects. Clinical data of the children were collected. Peripheral blood samples of the children and their parents were collected and subjected to whole exome sequencing (WES). Candidate variants of the NBAS gene were verified by Sanger sequencing. This study was approved by the Ethics Committee of the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2024-k-069). Results:The three children had presented with fever-triggered recurrent acute liver failure. All of them were found to harbor compound heterozygous variants of the NBAS gene, including c. 3596G>A and c.1181A>T in child 1, c.2617C>T and c. 2T>C in child 2, and c. 3596G>A and c. 2817_2818insT in child 3. Among these, the c. 1181A>T and c. 2817_2818insT variants were unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), they were respectively classified as variants of uncertain significance (PM2_Supporting+ PM3+ PP3) and pathogenic (PVS1+ PM2_Supporting+ PM3). Conclusion:Combined with the patient′s clinical phenotype, the compound heterozygous variants of the NBAS gene probably underlay the pathogenesis of ILFS2 in the three children. For children with fever-related acute liver failure of unknown causes, the possibility of this disease should be suspected, and genetic testing may facilitate the diagnosis. Early diagnosis and timely intervention can significantly improve the prognosis. Discoveries of the c. 1181A>T and c. 2817_2818insT variants have enriched the mutational spectrum of the NBAS gene.

Objective:To summarize Chinese materia medica with estrogen-activity based on data mining and analyze their characteristics.Methods:Literature was retrieved from CNKI, Wanfang Data, Chongqing VIP, CBM, PubMed and Web of Science from the establishment of the databases to June 30, 2024, and Chinese materia medica with estrogenic activity were screened. Excel 2021 and KH Coder 3.0 software were used to perform statistical and network co-occurrence analysis on the efficacy classification of Chinese materia medica, properties, tastes and meridians, screening methods for estrogen activity, and applications.Results:Totally 121 kinds of Chinese materia medica with estrogen-activity were included in total. The efficacy classifications were mostly tonic medicines, heat-clearing medicines and blood circulation promoting drugs. The properties were mainly warm and neutral, the tastes were mainly sweet and bitter, and the meridians were mainly the liver, kidney and spleen meridians. The network co-occurrence analysis of the efficacy classification, properties, tastes and tropism meridians showed that the clustering relationship of tonic medicine-neutral-sweet-liver-kidney was the most obvious. The screening methods mainly included MCF-7 cell proliferation and uterine weight gain experiments. Their applications mainly covered osteoporosis, perimenopausal syndrome, lipid metabolism disorder, and premature ovarian failure, etc.Conclusions:Chinese materia medica with estrogen-activity or their components act on estrogen target cells or organs to exert estrogen-like or antagonistic estrogenic effects. This kind of Chinese materia medica can regulate the body's qi, blood, yin and yang, the function of organs and the fullness of Tiangui, as well as the Chong meridian and Conception Vessel, thus improving human growth and development, reproduction and aging. In the future, it is suggested to explore their effective components, mechanisms, bidirectional effect and safety on the basis of guiding clinical medication with the theory of TCM, combining with modern medical research techniques and evidence-based medical research.
