1.New advances in the study of the etiology and treatment of floaters
International Eye Science 2025;25(3):446-450
As a common ophthalmic disease, floaters have a complex etiology. It involves changes in the structure and function of the vitreous body and is closely associated with factors like age and myopia. Vitreous liquefaction and posterior detachment play a crucial role in this regard. Clinically, patients usually experience the floating of dotted or linear black shadows in front of their eyes, and generally, floaters do not cause visual impairment. In the past, due to the limitations of traditional concepts and treatment methods, a conservative observation strategy was often adopted. However, an increasing number of patients have complained that floaters lead to difficulties in driving and reading, which seriously affects their visual quality and mental health. Consequently, the demand for treatment has been growing day by day. The existing treatment options each have their own advantages and disadvantages. The efficacy of drug treatment is limited and remains controversial. Vitrectomy has a definite curative effect, yet it comes with a high risk of complications. YAG laser vitreolysis is relatively safe, but its curative effect is restricted by factors such as the size and location of the opacities. Nanobubble-mediated vitreolysis is still in the research stage and is expected to offer patients safer and more effective treatment in the future. This article reviews the etiology of floaters and the latest progress in its treatment, aiming to deepen clinicians' understanding of floaters, provide a more comprehensive scientific basis for clinical diagnosis and treatment, and promote personalized and precise treatment.

OBJECTIVE To explore the effect and mechanism of Zhiqiao gancao decoction (ZQGCD) on pathological angiogenesis of degenerative intervertebral disc. METHODS The rats were randomly divided into sham operation group (normal saline), model group (normal saline), hypoxia inducible factor-1α (HIF-1α) inhibitor (YC-1) group [2 mg/(kg·d), tail vein injection], and ZQGCD low-dose, medium-dose and high-dose groups [3.06, 6.12, 12.24 g/(kg·d)], with 8 rats in each group. Except for sham operation group, lumbar disc degeneration model of rat was constructed in all other groups. After modeling, they were given relevant medicine once a day, for consecutive 3 weeks. After the last medication, pathological changes and angiogenesis of the intervertebral disc tissue in rats were observed; the levels of inflammatory factors [interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α)] and the expressions of angiogenesis-related proteins [HIF-1α, vascular endothelial growth factor (VEGF), VEGF receptor 2 (VEGFR2), angiotensin 1(Ang 1), Ang 2] in the com intervertebral disc tissue in rats were all determined. In cell experiment, the primary nucleus pulposus cells were isolated and cultured from rats, and cellular degeneration was induced using 50 ng/mL TNF-α. The cells were divided into blank control group (10% blank control serum), TNF-α group (10% blank control serum), YC-1 group (10% blank control serum+0.2 mmol/L YC-1), and 5%, 10%, 15% drug-containing serum group (5%, 10%, 15% drug-containing serum). After 24 hours of intervention, the nucleus pulposus cells were co-cultured with HUVEC. The expressions of Collagen Ⅱ, matrix metalloproteinase-3 (MMP-3) in nucleus pulposus cells were detected. HUVEC proliferation, migration and tube forming ability were detected, and the expression levels of the HIF-1α/VEGF/Ang signal axis and angiogenesis- related proteins (add MMP-2, MMP-9) in HUVEC were detected. RESULTS Animal experiments had shown that compared with model group, the positive expression of CD31 in the intervertebral disc tissues of rats in each drug group was down-regulated (P< 0.05), the levels of inflammatory factors and angiogenesis-related proteins were decreased significantly (P<0.05), and the pathological changes in the intervertebral disc were alleviated. Cell experiments had shown that compared with TNF-α group, the expression of Collagen Ⅱ in nucleus pulposus cells of all drug groups was significantly up-regulated (P<0.05), and the expression of MMP-3 was significantly down-regulated (P<0.05); the proliferation, migration and tubulogenesis of HUVEC were significantly weakened (P<0.05). The mRNA and protein expressions of HIF-1α, VEGF, Ang 2 as well as the expression of angiogenesis-related proteins (except for the expression of Ang 2 mRNA and HIF-1α, VEGFR2, Ang 2 protein in 5% drug- containing serum group) were significantly down-regulated (P<0.05). CONCLUSIONS ZQGCD may inhibit the HIF-1α/VEGF/ Ang signal axis to weaken the angiogenic ability of vascular endothelial cells, improve pathological angiogenesis in the intervertebral disc, and delay the degeneration of the intervertebral disc.

Objective:
To understand the health status of primary school freshmen in Guiyang and the health management service needs of parents after examination, so as to provide a reference for establishment of a collaborative health management framework involving schools, families, and healthcare providers.
Methods:
From September to October 2024, a stratified random cluster sampling method was used in Guiyang City to select 3 210 students and 3 133 parents who participated in the physical examination for primary school freshmen. Demographic indicators, physical examination indicators and laboratory examination indicators of students were collected, and parents needs for post examination health management service were investigated by self designed questionnaire. Multiple linear regression analysis was adopted to investigate the related factors of parents health management service needs after the examination.
Results:
The detection rates of common illness among primary school freshmen were 60.22% for dental caries, 17.23 % for screening myopia, 6.11% for obesity, 3.86% for iron deficiency anemia, and 1.15% for scoliosis. The co-occurrence rate of common illness among freshmen during the physical examination was 23.89% ( n =767), among which the comorbidity rate of screening myopia and dental caries (8.22%) and obesity and dental caries (4.27%) were higher. About 63.80% parents indicated that the physical examination items were simple, and 2 366 parents (75.52%) indicated a demand for post examination management services; the average score of parents demands for post examination services was (3.12±0.70). In terms of the scores of each dimension, the mean score of nutrition and health (3.58±0.74) was the highest, while the lowest mean score was for traditional Chinese medicine health care (2.77±0.67). The mean scores for the other dimensions were as follows:exercise intervention (3.29± 0.79 ), psychological monitoring (3.17±0.58), and health education and signing (2.81±0.73). The results of multiple linear regression analysis showed that parents educational level (junior high school, high school/vocational school, college/undergraduate and above), living conditions (floating), and children s illness status (1, 2, >3 types) were the related factors of parents health management service needs after the entrance examination for new students ( B =2.16, 3.07, 3.68; -2.19; 3.14, 3.34, 3.11, P <0.05).
Conclusions
The prevalence of common illness in primary schools in Guiyang is characterized by a heavy burden from single diseases, with a notable occurrence of multiple comorbidities. After the physical examination, parents have obvious demand for follow up health management services. These health management services should integrate the concept of multi disease prevention according to the needs of parents.

The pathogenesis of chronic wound healing is complex. It is often difficult to heal due to a long course of disease, difficulty in treatment, and it seriously affects the quality of life in patients. The active ingredients, couplet medicinals, and compound formulas of traditional Chinese medicine (TCM) possess unique advantages in the treatment of chronic wound healing. The phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway is extremely critical in the treatment of chronic wound healing by regulating a series of biological processes, including cell apoptosis, angiogenesis, and inflammatory responses. This article reviews the relevant research on the regulation of the PI3K/Akt signaling pathway by TCM to promote chronic wound healing. It has been found that the active ingredients of TCM (such as geniposide, astragaloside, and ginsenosides, etc.), and compound formulas (such as Chonghe ointment, Huanglian ointment, Shirun shaoshang ointment, etc.) mainly reduce inflammatory responses, promote angiogenesis, regulate cell autophagy, and accelerate wound healing by activating the PI3K/Akt signaling pathway; at the same time, there are also a few couplet medicinals( such as Huangqi-Honghua) and compound formulas (such as Xiangpi Shengji ointment) that exert anti-inflammatory effects by inhibiting this signaling pathway, to promote wound healing.

Chinese Journal of School Health 2025;46(4):552-557
Objective:
To explore the relationship between sleep characteristics, physical activity patterns, with depressive and anxiety symptoms in college students, so as to provide reference for student mental health promotion.
Methods:
From September to November 2023, a convenience sampling method was used to select 7 954 college students aged 18-22 years from 9 universities in Shanghai, Hubei, and Jiangxi. Assessments were conducted using the International Physical Activity Questionnaire Short-Form (IPAQ-SF), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and Pittsburgh Sleep Quality Index (PSQI) to evaluate physical activity, depressive and anxiety symptoms, and sleep quality, respectively. Logistic regression analysis was employed to explore the impact of sleep characteristics and physical activity patterns on depressive and anxiety symptoms and their comorbidity among college students.
Results:
The detection rates for depressive symptoms, anxiety symptoms, and comorbid depression and anxiety symptoms were 25.67%, 35.39%, and 23.15%, respectively. Factors such as gender, grade, household registration, parental education level, annual family income, family structure, and dietary habits were all associated with the detection rates of depressive and anxiety symptoms and their comorbidity (χ2=4.41-118.39, P<0.05). Physical activity patterns, sleep duration, sleep quality, and sleepwake characteristics were also associated with the occurrence of depressive and anxiety symptoms and their comorbidity (χ2=9.66-627.70, P<0.05). Logistic regression analysis showed that college students who stayed up late and slept less than 7 had the highest risk of depressive and anxiety symptoms and their comorbidity (OR=1.93, 1.85, 1.88, P<0.05). Compared to regular physical activity patterns, insufficient physical activity patterns were associated with an increased risk of depressive and anxiety symptoms (all OR=1.18, P<0.05). Further stratified analysis results showed that the risk of depression, anxiety and their comorbidity increased in college students who stayed up late and slept less than 7 h, went to bed before midnight and slept less than 7 h, or went to bed before midnight and slept more than 7 h but did not have sufficient physical activity (P<0.05).
Conclusions
Sleep characteristics and physical activity patterns significantly affect depressive and anxiety symptoms in college students. Universities should strengthen sleep management and implement flexible physical activity interventions to help students establish healthy lifestyles.

Diabetes & Metabolism Journal 2025;49(2):321-330
Background:
Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients.
Methods:
Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines.
Results:
Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher.
Conclusion
MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.
