AIM: To compare the clinical efficacy of goniosynechialysis versus trabeculectomy combined with cataract phacoemulsification in treating glaucoma complicated with cataract.METHODS:From January 2019 to January 2024, patients with glaucoma complicated with cataract diagnosed in our hospital were included as the study subjects. They were assigned into trabeculectomy group and goniosynechialysis group based on different surgical methods. The trabeculectomy group was treated with cataract phacoemulsification combined with trabeculectomy, while the goniosynechialysis group was treated with cataract phacoemulsification combined with goniosynechialysis. The improvement of visual acuity, anterior chamber depth, chamber angle width, intraocular pressure, whole en face vessel density within the optic disc head and in the peripapillary region, and complications were compared between two groups.RESULTS: A total of 120 patients(120 eyes)with glaucoma combined with cataract were included in this study, among which 60 eyes were in the trabeculectomy group and 60 eyes in the goniosynechialysis group. The age of the trabeculectomy group was 60.72±6.16 years, including 28 males and 32 females. The age of the goniosynechialysis group was 61.04±6.24 years, including 31 males and 29 females. At 3 mo after surgery, the visual acuity of patients in both groups improved significantly, and the improvement of visual acuity in the goniosynechialysis group was significantly better than that in the trabeculectomy group(all P<0.01). At 3 mo after surgery, the anterior chamber depth and chamber angle width of patients in both groups were higher than those before surgery, and with the goniosynechialysis group being higher than the trabeculectomy group(all P<0.01), while the intraocular pressure was lower than that before surgery, and with the goniosynechialysis group being lower than the trabeculectomy group(all P<0.01). Before surgery, there was no significant difference in the whole en face vessel density within the optic disc head between the two groups(P>0.05), however, the whole en face vessel density within the optic disc head in both groups on 1 d after surgery were significantly lower than before surgery(all P<0.05); and compared with 1 d after surgery, there was a significant increase at 1 wk, 1, and 3 mo after surgery(all P<0.05); the whole en face vessel density within the optic disc head in the goniosynechialysis group was significantly higher than that in the trabeculectomy group at various time points after surgery(all P<0.05). However, there was no significant difference in the whole en face vessel density in the peripapillary region between the two groups before surgery and various time points after surgery(all P>0.05). Within 3 mo after surgery, the incidence of complications in the goniosynechialysis group(8.3%)was significantly lower than that in the trabeculectomy group(21.7%; P<0.05).CONCLUSION:Goniosynechialysis combined with phacoemulsification is more effective than trabeculectomy combined with phacoemulsification in the treatment of patients with glaucoma complicated with cataract in improving the visual acuity and whole en face vessel density within the optic disc head of patients, increasing the anterior chamber depth and chamber angle width, reducing intraocular pressure and the risk of complications. It has high safety and ideal short-term efficacy.

Objective To explore the risk factors of progression to dementia within 2 years in patients with recent subcortical small infarction (RSSI) complicated with cognitive dysfunction. Methods A total of 340 patients with RSSI complicated with cognitive dysfunction who were treated in the hospital and completed 2-year follow-up were selected from February 2021 to February 2025. According to whether the patients progressed to dementia, they were classified into dementia group (n=105) and non-dementia group (n=235). The clinical data were compared between both groups, and the independent risk factors were screened by Logistic regression analysis. Results Multivariate logistic regression analysis suggested that history of hypertension (OR=1.919), history of diabetes mellitus (OR=1.597), multiple infarctions (OR=1.455), severe white matter lesions (OR=1.595), no cognitive function training (OR=1.923), increased infarct size (OR=1.069), reduced MMSE score (OR=0.945) and increased levels of NfL (OR=1.049) and IL-6 (OR=1.038) were independent risk factors for the progression to dementia (all P<0.05). Conclusion The progression to dementia in patients with recent subcortical small infarction and cognitive dysfunction is affected by multiple factors. In clinical practice, the integration of vascular risk factors, imaging features, cognitive assessment and serum biomarkers (NfL, IL-6) helps to construct an early risk prediction model and implement targeted interventions for high-risk groups.
3.Correlation between depressive symptom and traditional Chinese medicine constitution among school aged children and adolescents
Chinese Journal of School Health 2025;46(9):1222-1225
Objective:
To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom.
Methods:
From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted.
Results:
The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05).
Conclusions
Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

OBJECTIVE To study the effects of peripheral blood-derived exosomes (Exo) intervened by Naozhenning (NZN) on injury of neuron cells HT22 induced by microglia BV-2 cells. METHODS Wistar rats were selected to prepare peripheral blood- derived Exo intervened by NZN (66.83 g/kg), referred to as NZN-Exo; peripheral blood-derived Exo intervened by normal saline and piracetam (PLXT, 1.62 g/kg) were prepared using the same method, denoted as KB-Exo and PLXT-Exo respectively, and all Exo were subsequently identified. Meanwhile, BV-2 cells were stimulated with 1 μg/mL lipopolysaccharide (LPS) to prepare LPS- stimulated supernatant, and non-LPS-stimulated supernatant was prepared following the same protocol. HT22 cells were divided into four groups: KB-Exo group (treated with non-LPS-stimulated supernatant+KB-Exo), model group (treated with LPS-stimulated supernatant+KB-Exo), PLXT-Exo group (treated with LPS-stimulated supernatant+PLXT-Exo), and NZN-Exo group (treated with LPS-stimulated supernatant+NZN-Exo), with the concentration of the corresponding Exo in all groups being 50 μg/mL. After 24 hours of culture, the proliferation of HT22 cells was detected by the CCK-8 assay and EdU assay; the apoptosis of HT22 cells was detected; the microstructure of HT22 cells was observed; the contents of interleukin-1β (IL-1β), IL-10, nuclear factor-κB (NF- κB), and tumor necrosis factor-α (TNF-α) in HT22 cells were measured, as well as the expression levels of TNF-α, NOD-like receptor thermal protein domain associated protein 3 (NLRP3), Caspase-1, B-cell lymphoma-2( Bcl-2), and Bcl-2-associated X protein (Bax). RESULTS KB-Exo, PLXT-Exo and NZN-Exo were successfully prepared, and all Exo exhibited typical cup-shaped contours and membrane-enclosed characteristics. Compared with KB-Exo group, model group showed significantly decreased cell proliferation rates (detected by CCK-8 and EdU), intracellular IL-10 levels, and Bcl-2 protein expression levels (P<0.05); while the cell apoptosis rate, intracellular levels of IL-1β, TNF-α, and NF-κB, as well as the expression levels of NLRP3, TNF-α, Caspase-1, and Bax proteins were significantly increased (P<0.05). Additionally, in the model group, the cells showed volume swelling, incomplete cell membrane, nucleolar rupture, significant swelling and deformation of mitochondria, and severe vacuolization. Compared with model group, the above quantitative indicators in the PLXT-Exo group and NZN-Exo group were significantly reversed (P<0.05), with large and round cell nuclei, intact nuclear membranes, and reduced mitochondrial vacuolization. CONCLUSIONS Peripheral blood-derived Exo intervened by naozhenning can alleviate the injury of neuronal cells HT22 by inhibiting inflammatory responses and cell apoptosis.

ObjectiveTo construct a comprehensive evaluation indicator system for clinical practice guidelines of traditional Chinese medicine (TCM) that is scientific, systematic, and reflects the characteristics of TCM. MethodsA systematic search was conducted in Chinese and English databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, and Cochrane Library, to include literature on domestic and international guideline evaluation tools and TCM-related research. Document analysis and CiteSpace were utilized for keyword co-occurrence and clustering analysis. ResultsA total of 65 relevant studies were included, from which seven core thematic domains were identified. Based on the research objectives, a two-step construction strategy was adopted: first, an external evaluation framework was established by referencing international tools to cover methodological rigor and procedural standardization; second, an internal evaluation framework was developed to reflect the distinctive features of TCM clinical practice, including syndrome differentiation and efficacy feedback. Through expert consensus, the indicator system was refined, resulting in a dual-layered structure comprising 8 primary indicators, 22 secondary indicators, and 62 evaluation criteria. ConclusionThe comprehensive evaluation system for TCM clinical practice guidelines, based on bibliometric analysis and core element extraction, integrates both theoretical integrity and practical applicability. This study provides a preliminary research foundation for further optimization, validation, and development of a refined comprehensive evaluation system.

Objective To develop and validate a scoring system to predict the possibility of laparoscopic cholecystectomy (LC) conversion to laparotomy based on preoperative clinical data, and to establish a grading management model of surgery. Methods A retrospective analysis was conducted on the clinical data of 9 414 patients who underwent LC at Renhe Hospital and Huashan Hospital from June 2013 to June 2018. The patients were divided into two groups: the LC group (9 246 patients who successfully underwent LC) and the conversion to laparotomy group (168 patients who required conversion to open surgery). The data of two groups were compared, and the risk factors affecting conversion to laparotomy were screened out by single factor analysis of Chi-square test. Then, the risk factors were analyzed by multiple Logistic regression, and the pre-coefficient of each variable of the risk factors was assigned according to the established conversion to laparotomy possibility function. After calculating the score of each case, the difference in the actual conversion rate of each group was compared. The area under receiver operating characteristic (ROC) curve was calculated to evaluate the performance of the scoring system. According to the scoring system, LC surgical grading management model was created and verified. Results The following factors were identified as significant risk factors for conversion to laparotomy (P < 0.001): body temperature ≥ 38.5℃, frequency of acute cholecystitis ≥3 times, maximum thickness of gallbladder wall ≥ 5 mm, gallbladder neck stone incarceration, diameter of common bile duct ≥8 mm, and surgical experience ≤50 cases were the risk factors for conversion to laparotomy (P < 0.001). A score >3 points was associated with a high risk of conversion to laparotomy. Conclusions The LC scoring system and surgical grading management are reliable and effective tools for predicting and reducing the conversion rate of LC to laparotomy.

OBJECTIVES:
Neurodegenerative diseases are closely associated with myelin loss, and the proliferation and differentiation of oligodendrocyte precursor cells (OPCs) are crucial to remyelination. However, the regulatory mechanisms involved remain incompletely understood. This study aims to investigate how astrocytes (ASTs) regulate the secretion of chitinase-3-like protein 1 (CHI3L1) via connexin 47 (Cx47)-mediated exosome signaling, and its subsequent effect on OPC proliferation.
METHODS:
Primary cells were isolated from postnatal day 1 Sprague-Dawley (P1SD) rats to establish 3 culture conditions: OPCs alone (Group O), OPCs in direct contact with ASTs (Group C), and OPCs cultured with AST-conditioned medium (Group A). Cellular morphology and proliferation were assessed using optical microscopy, 5-ethynyl-2'- deoxyuridine (EdU) incorporation, and flow cytometry. RNA sequencing (RNA-Seq) and bioinformatics analysis (BA) were conducted to identify differentially expressed genes (DEGs) among groups. Protein expression and cell cycle distribution were analyzed by Western blotting (WB) and flow cytometry. Exosomes were isolated and purified via differential centrifugation, characterized by nanoparticle tracking analysis (NTA) and transmission electron microscopy (TEM), and CHI3L1 expression in exosomes was verified via WB. Cx47 was silenced using small interfering RNA (siRNA) to evaluate its effect on OPC proliferation and exosome secretion. Artificial exosomes were constructed by encapsulating CHI3L1 in single unilamellar vesicles (SUVs), whose structure and size were validated by NTA and TEM. Following Cx47 knockdown, artificial exosomes were added back, and OPC proliferation was assessed via flow cytometry and EdU assay.
RESULTS:
Direct co-cultured with ASTs (Group C) resulted in significantly enhanced OPC proliferation compared to the Group O and Group A (P<0.05). RNA-Seq and WB analyses revealed that ASTs promote OPC proliferation and exosome secretion enriched in CHI3L1 through Cx47. Cx47 knockdown by siRNA led to significant decreases in OPC proliferation and exosome release (P<0.05). The inhibitory effect of Cx47 silencing on OPC proliferation was partially reversed by supplementation with either isolated exosomes or exogenous CHI3L1.
CONCLUSIONS
This study reveals a novel mechanism by which ASTs regulate OPC proliferation: Through direct contact, ASTs enhance the secretion of CHI3L1-rich exosomes via Cx47, thereby converting intercellular contact signals into secretory signals that promote OPC proliferation. As a key exosomal molecule, CHI3L1 may play an important role in neural function and remyelination and warrants further investigation.

Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a rare autosomal dominant hereditary disorder characterized by hyperuricemia, gout, impaired urinary concentration, and progressive renal failure. It is primarily caused by mutations in uromodulin (UMOD) gene. This study reports a family with ADTKD in which whole-exome sequencing and Sanger sequencing identified a missense mutation in the UMOD gene, c.761A>C (p.H254P), present in both the proband and affected relatives. According to American College of Medical Genetics and Genomics (ACMG) guidelines, this variant is classified as likely pathogenic. The mutation results in an amino acid substitution that may impair UMOD protein folding and intracellular trafficking. UMOD gene mutations are associated with ADTKD, and genetic testing plays a vital role in the early diagnosis and treatment of this condition, highlighting its importance in the diagnosis of rare kidney diseases.

Dent disease is a rare X-linked recessive inherited renal tubular disorder characterized by low molecular weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis, and other clinical features, and can lead to progressive renal failure. It is primarily caused by mutations in the CLCN5 gene. This article reports the case of a 10-year-old male patient of Chinese descent who was incidentally found to have asymptomatic proteinuria during a routine health examination. Comprehensive biochemical testing and clinical evaluation revealed significant LMWP and hypercalciuria, while renal biopsy showed mesangial cell and matrix proliferation. Whole exome sequencing identified a novel deletion mutation in the CLCN5 gene (NM_001127899.4, c.1158delC, p.F387Lfs*42) causing a frameshift and premature termination, which is likely to disrupt its role in chloride/hydrogen ion exchange and endosomal acidification. Bioinformatic analysis indicated the variant is pathogenic. Genetic testing plays an important role in diagnosing rare kidney diseases. Early identification of pathogenic mutations is essential for facilitating timely intervention and appropriate management, potentially enhancing patient outcomes. This report expands the CLCN5 mutation spectrum and contributes to understanding the genetic and molecular mechanisms of Dent disease.
