OBJECTIVE: To explore the clinical features, genetic characteristics in a child with Miller-McKusick-Malvaux syndrome (3MS) type 1 caused by CUL7 gene variant. METHODS: A child diagnosed with 3MS type 1 at the Children's Hospital Affiliated to Zhengzhou University in February 2021 was selected as the subject of this study. Peripheral blood samples were collected from the child and her parents for genomic DNA extraction. Whole exome sequencing (WES) was performed on the child, and Sanger sequencing was used to validate the candidate variants and analyze their pathogenicity. A literature search was conducted using the keywords "3M syndrome" in the China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and PubMed databases from inception to December 2024. The clinical data of Chinese children with 3MS reported in the literature were summarized. This study was approved by the Medical Ethics Committee of the Children's Hospital Affiliated to Zhengzhou University (Ethics No. 2024-K-020). RESULTS: The child was a 6-year-old and 2-month-old female with facial dysmorphism, skeletal abnormalities, and growth and developmental delay. WES revealed compound heterozygous variants in the CUL7 gene: c.2686G>T (p.E896*) and c.1200delT (p.R401Gfs66). Sanger sequencing confirmed that these two variants were inherited from the child's father and mother, respectively. According to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants, c.2686G>T (p.E896) was classified as a pathogenic (PVS1+PM2_Supporting+PM3), and c.1200delT (p.R401Gfs*66) was classified as a likely pathogenic (PVS1+PM2_Supporting). Based on the literature search strategy, 18 relevant articles were identified, including a total of 32 Chinese cases of 3MS, of which 8 were fetuses. A total of 32 Chinese 3MS cases were included in the literature review, of which 8 were fetuses. The majority of these cases carried variants in the CUL7 gene (20/32, 62.5%) and OBSL1 gene (12/32, 37.5%). The main clinical manifestations included intrauterine or postnatal growth and developmental delay (32/32, 100.0%), triangular facies (27/32, 84.3%), and skeletal abnormalities (21/32, 65.6%). CONCLUSION The compound heterozygous variants c.2686G>T (p.E896*) and c.1200delT (p.R401Gfs*66) in the CUL7 gene are likely the genetic cause of 3MS type 1 in the child. For children presenting with facial dysmorphism, skeletal abnormalities, and intrauterine or postnatal growth and developmental delay, 3MS should be considered as a differential diagnosis.

Objective:To analyze the current research hotspots and trends of traditional Chinese medicine (TCM) treatment for neurogenic bladder (NB).Methods:The Chinese and English articles on TCM treatment of neurogenic bladder were searched in CNKI, Wanfang Database, PubMed, and Web of Science from the inception to May 31, 2024, using the terms "neurogenic bladder" "intervention" "treatment" "clinical" "Chinese medicine" "electroacupuncture" "acupuncture", and "moxibustion". VOSviewer and Citespace bibliometric software were used to analyze the publication trend, authors, research institutions, source journals and keywords of these articles.Results:A total of 776 Chinese articles and 253 English articles on the diagnosis and treatment of NB by traditional Chinese medicine were retrieved, the number of publications was increasing every year. Most Chinese papers came from Shandong University of Traditional Clinese Medicine, and most English papers came from Sun Yat-sen University. Some authors and institutions had formed networks of cooperation. Most papers were published in the journal of Traditional Chineses Medicine Clinical Research (in Chinese) and Neural Regeneration Research (in English). This study generated 244 Chinese core key words with 14 clustering networks, and 233 English core key words with 10 clustering networks. The main symptoms of NB are uroschesis and urinary incontinence. NB are primarily caused by spinal cord injury, diabetes mellitus and stroke. The main treatment methods of TCM for NB are electroacupuncture, acupuncture and percutaneous acupoint electrical stimulation. The research on NB mechanisms focuses on the apoptosis, regeneration and plasticity of spinal neurons, the activation of the bladder autophagy signaling pathway, the expression of proteins related to the contractile function of the forced muscles. Conclusion:The research quantity and quality of traditional Chinese medicine in diagnosis and treatment NB have increased in recent years, and the mechanism and treatment of NB are the research hotspots; however, the extension and depth of researches are limited, and the institutional cooperations are insufficiente.

Objective:To systematically evaluate the associations of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) with post-stroke depression (PSD).Methods:PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang databases were searched to collect literature comparing levels of CRP, IL-6, and TNF-α at the peripheral blood between PSD and non-PSD patients, with retrieval time limit from inception to June 2024. Literature was screened according to inclusion and exclusion criteria, and data were extracted. Newcastle-Ottawa Scale (NOS) was used to assess the quality of included literature. Meta analysis was conducted using Stata 18.0 software, and publication bias was assessed.Results:A total of 21 pieces of literature with 3,177 participants were collected, including 1,425 patients with PSD and 1,752 patients with non-PSD. Meta analysis results showed that CRP level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients (standardized mean difference [ SMD]=0.930, 95% CI: 0.580-1.280, P<0.001). Subgroup analysis results showed that, among the 7 pieces of literature with CRP detection<14 days after stroke, CRP level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients ( SMD=0.640, 95% CI: 0.38-0.89, I2=83.9%, P<0.001); among the 4 pieces of literature with CRP detection≧14 days after stroke, CRP level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients ( SMD=1.450, 95% CI: 0.820-2.090, P<0.001), enjoying higher heterogeneity ( I2=90.6%). IL-6 level at the peripheral blood in PSD patients was significantly higher than that in non-PSD patients ( SMD=2.659, 95% CI: 1.583-3.735, P<0.001). No significant difference in TNF-α level at the peripheral blood was noted between PSD patients and non-PSD patients ( SMD=0.403, 95% CI: -0.208-1.014, P=0.196). Conclusion:CRP and IL-6 levels at the peripheral blood in PSD patients are obviuosly higher than those in non-PSD patients, suggesting that CRP and IL-6 may be potential biomarkers for early identification and intervention of PSD.
