ObjectiveTo explore the effects of Jingui Shenqiwan (JSW) and Liuwei Dihuangwan (LDW) on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group, the other six groups were as follows: a group of both males and females receiving JSW (3.0 g·kg-1), a group of both males and females receiving LDW (4.5 g·kg-1), a group of males receiving water and females receiving JSW, a group of males receiving water while females receiving LDW, a group of females receiving water while males receiving JSW, and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 (female∶male) ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth, which was followed by the observation of newborn mice, calculation of their average number, and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment, the weights of the thymus and spleen were measured to calculate the organ coefficients, and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems, while novel object recognition test (NOR) was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction (Real-time PCR) assay, and protein expression was analyzed with Western blot. ResultsCompared with the control group, oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together (P<0.05), while LDW showed a trend but no statistical significance. Additionally, compared with the control group, JSW could upregulate the gene expression of gonadotropin-releasing hormone (GnRH) in the thalamus, as well as reproductive stem cell factor (SCF) and tyrosine kinase receptor (c-Kit) in the testes and reproductive stem cell marker mouse vasa homologue (MVH) in the ovaries, upregulate the expression of proteins influencing neuronal functional activity, such as brain-derived neurotrophic factor (BDNF), in hippocampal neurons (P<0.05), and enhance sucrose preference in male mice (P<0.05). Compared with the control group, JSW significantly increased sucrose preference and novel object recognition index in offspring mice (P<0.05), which was related to the upregulation of hippocampal dopamine D1 receptor (D1R) and N-methyl-D-aspartate receptor (Nmdar) gene expression. Compared with the control group, both JSW and LDW could upregulate the protein expression of glucocorticoid receptor (GR), BDNF, and tyrosine kinase receptor B (TrkB) in the hippocampus of offspring mice (P<0.05). ConclusionJSW significantly enhances the reproductive ability of normal mice, which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally, JSW has a certain regulatory effect on the brain function of the offspring mice.

OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

ObjectiveTo explore the effect of Shenge Bushen Capsules (SBC) on sexual development in normal 3-week-old mice. MethodsThe experiment consisted of two parts. In the first part, mice were divided into four groups: The control group and the low, medium, and high-dose SBC groups (234.7, 469.4, 938.7 mg·kg-1, respectively). In the second part, mice were divided into four groups: Control group, Pseudostellariae Radix polysaccharide (PRP) group, total flavonoids group, and SBC group, all receiving a dose of 469.4 mg·kg-1. After 7 days of administration, the vaginal opening of female mice and the descent of testes and scrotum in male mice, as well as the ovarian and testicular organ indices, were observed. After 4 weeks of administration, female and male mice were housed together for 2 days, and the pregnancy rate of females was monitored. After delivery, the pregnant female mice continued receiving the treatment for 4 weeks, and the sexual development of their offspring, including vaginal opening, testicular descent, and organ indices of ovaries and testes, was observed. Serum sex hormones were measured by enzyme-linked immunosorbent assay (ELISA), and the expression of gonadotropin-releasing hormone (GnRH) and growth hormone (GH) proteins in the hypothalamus was assessed by Western blot. ResultsCompared with the control group, there was no significant effect on the vaginal opening of female mice or the descent of testes in male mice after 7 days of SBC administration. After 4 weeks of administration, the pregnancy rate in the low-dose group was significantly reduced (P<0.05), but no significant effects were observed in the other groups. The three doses of SBC did not significantly affect the ovarian or testicular organ indices, and there was no significant upregulation in the expression of GnRH or GH in the hypothalamus. The primary component of SBC, Pseudostellariae Radix polysaccharide, significantly reduced the vaginal opening in female mice after 7 days of administration (P<0.05). After 4 weeks, the serum estradiol levels of non-pregnant female mice were decreased (P<0.05), but there was no significant effect on the expression of GnRH or GH proteins in the hypothalamus of either male or female mice. Additionally, there were no significant effects on precocious puberty indicators, such as vaginal opening and testicular descent, in the offspring mice. ConclusionSBC does not significantly promote precocious puberty in young mice, and it does not have any noticeable effects on the pregnancy rate of adult mice or the sexual development of their offspring.

Objective To construct an optimal prediction model of chickenpox in Urumqi, and to provide reference for formulating the prevention and control strategies of chickenpox. Methods The multivariate autoregressive moving average model (ARIMAX) and random forest model (RF) were established based on the monthly incidence of chickenpox in Urumqi from 2014 to 2018, and the monthly incidence of chickenpox in 2019 was used to test the models and evaluate their prediction effect. The prediction performance of the two models was compared, and the best model was selected to predict the incidence of chickenpox in Urumqi. Results The incidence of chickenpox in Urumqi showed a regular bimodal distribution with obvious seasonality, and it showed a slow upward trend from July 2014 to December 2019. The fitting model was ARIMA(0,1,0)(0,1,1)12, the root mean square error (RMSE) and mean absolute error (MAE) of ARIMAX model training set were 1.29 and 0.95, respectively, and the RMSE and MAE of the test set were 1.88 and 1.44, respectively. The training set RMSE and MAE of RF model were 1.56 and 1.56, respectively, and the test set RMSE and MAE were 4.83 and 3.96, respectively. Conclusion The performance of ARIMAX model is better than that of RF model, which can better predict the incidence trend of chickenpox in Urumqi. It is necessary to optimize the prediction model according to the actual situation and provide scientific guidance for the prevention and control of chickenpox.

Diabetic retinopathy(DR)has emerged as the leading cause of vision loss among working-age people in many countries under the increasing prevalence of diabetes and the longevity of the population. The pathogenesis of DR is complicated and has not been fully elucidated at present, while the treatment methods of DR have not been greatly improved, mainly retinal laser photocoagulation, anti-vascular endothelial growth factor(VEGF)treatment and vitrectomy surgery. The current treatment methods not only have shortcomings, but also bring serious economic burden to patients. Therefore, new methods are needed to explore the pathogenesis of DR, discover new treatments or improve current treatments, and improve the satisfaction of DR patients. In recent years, the identification and quantification of proteins expressed in blood, retina, vitreous humor, aqueous humor, and tears of all observable DR patients and DR rats and differentially expressed proteins after drug intervention have provided new ideas for further exploring the pathogenesis, diagnosis and treatment of DR with the rise of proteomics, which put forward new insights into early detection and treatment.The proteomics of DR in recent years are reviewed, in order to provide new ideas for the diagnosis and treatment of DR.
6.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 mechanism of isorhamnetin (Iso) in the treatment of oral squamous cell carcinoma (OSCC) using network pharmacology and molecular docking methods and to verify it in vitro.
Methods :
The key targets were obtained by constructing the PPI protein interaction network based on the common intersection targets of Iso-OSCC. At the same time, gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) were used to analyze the related signaling pathways of the intersection targets. Iso and core targets were also analyzed through molecular docking and visualization. Colony formation assay and Transwell assay were used to identify the effect of Iso on the proliferation and invasion of Cal-27 cells. Western blot was used to analyze the regulatory effects of different concentrations of Iso on estrogen receptor-1 (ESR1), phosphoinositide-3-kinase regulatory subunit-1 (PIK3R1), Src tyrosine kinase (SRC), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway proteins.
Results:
A total of 269 potential intersection targets of Iso-regulated OSCC were obtained. According to the degree obtained by topological analysis, PIK3R1, AKT1, SRC, ESR1, and other core targets were screened out. KEGG analysis showed that 165 signaling pathways were enriched in the intersection targets of Iso-OSCC, among which the PI3K/AKT signaling pathway played an important role in the treatment of OSCC with Iso. Molecular docking results showed that the absolute value of binding energy between target proteins PIK3R1, AKT1, SRC, ESR1, and Iso was high. After Cal-27 cells were treated with Iso, the number of cell colony formations, the number of transmembrane cells, and the expression of PIK3R1, ESR1, SRC, p-PI3K, and p-AKT were negatively correlated with the increase in Iso concentration (P < 0.05).
Conclusion
Iso can inhibit PI3K/AKT signal transduction and influence the expression of PIK3R1, AKT1, SRC, and ESR1 proteins, thereby inhibiting the occurrence and development of OSCC.

Background Polystyrene microplastics (PS-MPs) attract widespread public attention due to their adverse effects on mammalian reproductive systems. However, it is currently unclear whether ferroptosis is related to testicular damage and decreased sperm quality in mice exposed to PS-MPs. Objective To clarify the reproductive damage in male mice exposed to PS-MPs and investigate the mechanism of ferroptotic effects. Methods Five-week-old male BALB/c mice were randomly divided into four experimental groups, including one control group and three PS-MPs groups at low dose (0.5 mg·kg−1), medium dose (5 mg·kg−1), and high dose (50 mg·kg−1), respectively, with 6 mice in each group. The treatment was delivered by gavage for 35 consecutive days (one time per day). After the mice were neutralized, the wet weights of testis and epididymis were measured, and organ coefficients were then calculated. Sperm was counted by hematimetry, and sperm motility and adenosine triphosphate (ATP) level were evaluated using CCK-8 and CellTiter Glo ® Kit 2.0 Assay respectively. In addition, serum testosterone, follicle-stimulating hormone, and luteinizing hormone were determined using ELISA kit, total testicular iron content was measured using tissue iron kit, and pathological changes in testicular tissue were observed after hematoxylin-eosin (HE) staining. We also used glutathione (GSH), malondialdehyde (MDA), and superoxide dismutase (SOD) assays to examine their changes to better understand the physiological status of testicular tissue. Finally, the expression levels of ferroptosis-associated proteins glutathione peroxidase 4 (GPX4) and solute carrier family 7 member 11 (SLC7A11) were detected by Western blotting. Results Compared with the control group, the testicular index in the high dose group decreased, and the epididymal index decreased in all dose groups (P<0.05). The results of sperm quality analysis showed that the sperm count in each dose group was lower than that of the control group; the sperm motility decreased, sperm malformation rate increased, and ATP level in sperm decreased in the medium and high dose groups. The results of HE staining showed that the spermatogenic epithelium was disordered and the arrangement of spermatogenic cells were loose in the low dose group, the spermatogenic gap was enlarged in the middle dose group, and the cells in the high dose group were vacuolated and even azoospermic. The results of serum sex hormone levels showed that the serum testosterone levels decreased in each dose group, the serum follicle-stimulating hormone levels decreased in the medium and high dose groups, and the serum luteinizing hormone levels decreased in the high dose group (P<0.05). The iron content in the testicular tissue homogenate of the high dose group increased (P<0.05). The levels of GSH and SOD in the homogenate of testicular tissue decreased in the medium and high dose groups, while the levels of MDA increased (P<0.05). The results of Western blotting showed that the protein expression level of GPX4 in the testis in the high dose group was lower than that in the control group. The protein expression levels of SLC7A11 in the medium and high dose groups were lower than that in the control group. The results of correlation analysis showed that the expression level of GPX4 was positively correlated with sperm count, and negatively correlated with MDA level (P<0.05). SLC7A11 expression level was positively correlated with sperm count, and negatively correlated with sperm malformation rate and MDA level (P<0.05). Conclusion PS-MPs exposure leads to decreased sperm quality, testicular damage, and decreased serum sex hormone levels in male mice, and its mechanism of action may involve ferroptosis.
