ObjectiveTo establish a model of dry eye with lung Yin deficiency syndrome in mice. MethodsA total of 40 SPF C57BL/6J mice were assigned via the random number table method into 5 groups (n=8): Normal control, model control, and high-, medium-, and low-dose (11.7, 5.85, and 2.925 g·kg-1, respectively) Yangyin Qingfeitang. Mice in the normal control group were fed normally without any intervention. Mice in Yangyin Qingfeitang group and model control group were treated with 0.2% benzalkonium chloride eye drops (5 μL) twice a day and fed in a controlled drying system in a dry environment for 28 days. At the same time, the mice were administrated with thyroxine tablet solution by gavage and placed in a glass fumigation tank (SO2 concentration: 0.5 g·m-3) for 14 days. After 4 weeks, mice in Yangyin Qingfeitang groups were treated with Yangyin Qingfeitang by gavage and those in the normal control group and model control group were administrated with deionized water at 0.01 mL·g-1. The body mass, anal temperature, four examination information (claw and nail appearance), basic tear secretion test, tear film rupture time, corneal fluorescein staining, and lacrimal gland HE staining were compared among groups. Compound Yangyin Qingfeitang granules were used to measure the syndrome to verify the success of modeling. ResultsAfter 28 days of continuous modeling, compared with the normal control group, the model group exhibited listless and emaciated status, coughing, drowsiness, dry and dull hair, dry and hard stool, reduced food intake and water intake, red lip circumference, red tongue with reduced fluid, dry nose and teeth, red claws and nails, body mass gain, decreased anal mild tear secretion (P<0.05), and shortened tear film rupture time (P<0.05). After 28 days of modeling, the mice showed large corneal fluorescein staining range, severe corneal injury, and increased content of interleukin (IL)-18, IL-β, and tumor necrosis factor (TNF)-α in lacrimal gland, compared with those in the normal control group (P<0.05). After the treatment with Yangyin Qingfeitang, the mice had good drinking and eating conditions, with lighter redness of the tongue, moist nose, moist and shiny teeth, and the claw and nail color close to that in the normal group. Compared with the model control group, Yangyin Qingfeitang groups showed increases in body mass and anal temperature (P<0.05), tear secretion (P<0.05), and tear film rupture time (P<0.05), narrowed range of corneal fluorescein staining, and declined levels of IL-18, IL-β, and TNF-α in lacrimal glands (P<0.01). The high-dose group had the best effect, with the indicators close to the levels in the normal control group. ConclusionThe animal model of dry eye with lung Yin deficiency syndrome can be established by culture in a controlled drying system, treatment with benzalkonium chloride eye drops for 28 days, and administration of thyroxine tablet solution combined with SO2 fumigation for 14 days.

ObjectiveTo investigate the mechanisms of Runmu Dihuang decoction (RMDHD) in treating perimenopausal dry eye with liver-kidney Yin deficiency syndrome based on the silent information regulator 3 (SIRT3)/hypoxia-inducible factor-1α (HIF-1α)/nuclear factor-κB (NF-κB) signaling pathway. MethodsSixty female Sprague-Dawley rats were randomly divided into six groups (n=10 per group): Sham operation group, model group, sodium hyaluronate eye drop group, and low-, medium-, and high-dose RMDHD groups (5.625, 11.25, 22.50 g·kg-1). Except for the sham operation group, all rats underwent bilateral ovariectomy and were administered 0.1% benzalkonium chloride eye drops combined with long-term chronic irritation to establish a perimenopausal dry eye model with liver-kidney Yin deficiency syndrome. Drug administration began in the 11th week after modeling and continued for 21 days. General conditions, screen-grip test scores, tear secretion volume, tear film breakup time (TFBUT), and corneal fluorescein staining were recorded. Serum levels of reactive oxygen species (ROS), follicle-stimulating hormone (FSH), estradiol (E2), and progesterone (PROG) were measured by enzyme-linked immunosorbent assay (ELISA). Pathological changes in the lacrimal glands, corneas, and uteri were observed using hematoxylin-eosin (HE) staining. Protein expression levels of SIRT3, HIF-1α, phosphorylated NF-κB p65 (p-NF-κB p65), and total NF-κB p65 in the lacrimal glands were detected by Western blot. The expression of inflammatory cytokines interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lacrimal glands was assessed by immunohistochemistry (IHC). ResultsAfter model establishment, no significant differences were observed among the groups except the sham operation group. Compared with the sham operation group, the other groups exhibited slowed movement, dull responses, increased irritability, reduced body weight, elevated rectal temperature, decreased screen-grip test scores, reduced tear secretion, and significantly shortened TFBUT (P<0.05). After treatment, compared with the model group, the sodium hyaluronate eye drop group and all RMDHD groups showed improved general conditions, significantly increased tear secretion (P<0.05), prolonged TFBUT (P<0.05), and elevated screen-grip test scores (P<0.05). Serum ROS and FSH levels were significantly decreased, while E2 and PROG levels were significantly increased (P<0.05). Pathological damage to the cornea, lacrimal glands, and uterus was ameliorated. In addition, protein expression levels of SIRT3 and HIF-1α in the lacrimal glands were significantly upregulated (P<0.05), whereas the expression of p-NF-κB p65, IL-1β, and TNF-α was significantly downregulated (P<0.05). ConclusionRMDHD increases tear secretion and TFBUT, improves lacrimal gland and corneal injury, and alleviates dry eye symptoms in a perimenopausal dry eye rat model with liver-kidney Yin deficiency syndrome. The underlying mechanism may be related to regulation of the SIRT3/HIF-1α/NF-κB signaling pathway, inhibition of oxidative stress and inflammatory responses, and reduction of ocular surface tissue damage.

Objective To explore the analytical methods combining multicolor flow cytometry with bioinformatics techniques for analyzing myeloid cells in the gastrocnemius of mice after muscle injury, and provide an experimental foundation for the study of muscle regeneration mechanisms. Methods Immune cells were collected from single-cell suspensions of mouse gastrocnemius using multicolor flow cytometry, and data were analyzed by the t-distributed stochastic neighbor embedding(t-SNE)algorithm supplemented by manual gating techniques. The tSNE algorithm was used in multicolor flow cytometry to guide the setting of manual gates, optimize the identification and classification of cell populations. Results Compared to the sham surgery group, the proportions of dendritic cells, granulocytes, macrophages, and monocytes at the site of muscle injury in the model group significantly increased, with the increasing in monocytes being particularly notable. Conclusion The application of the tSNE algorithm combined with manual gating techniques in multicolor flow cytometry demonstrated that this method could effectively guide the setting of manual gates and enhance the efficiency of distinguishing immune cell types. Through this combined technology, the function and subtypes of myeloid cells in the mouse gastrocnemius could be analyzed more accurately.

Objective:To investigate the relationship between lipid levels and cognitive impairment in the elderly Chinese population using prospective cohort data.Methods:Based on the China-PAR (Prediction for Atherosclerotic Cardiovascular Disease Risk in China) cohort, this study included 24 380 individuals aged ≥60 years who participated in the cognitive function follow-up survey from 2018 to 2019. Cognitive function was assessed using the Mini-Mental State Examination (MMSE), with cognitive impairment defined according to different educational levels: MMSE ≤17 for illiterate individuals, MMSE ≤20 for those with primary education and MMSE ≤24 for those with secondary education or above. Multivariable linear regression and logistic regression models were employed to examine the associations between six baseline lipid indicators and cognitive scores, as well as cognitive impairment. Additionally, restricted cubic splines were used to explore the exposure-dose relationship between lipid levels and cognitive function.Results:The study population had a median follow-up time of 11.6 years, with a baseline age of (59.7±6.8) years. Among the participants, 9 510 (39.0%) were males, and the mean MMSE score was 24.7±6.8. A total of 3 887 individuals (15.9%) were identified as cognitively impaired. The results of multivariable linear regression and logistic regression indicated that total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) levels were not only significantly positively associated with cognitive scores but also significantly associated with a lower risk of cognitive impairment. Each 1 mmol/L increase in these lipid levels corresponded to β values (95% CI) of 0.267 (0.173-0.361), 0.385(0.271-0.499) and 0.331(0.231-0.431), respectively. Each 1 mmol/L increase in these lipid levels corresponded to odds ratio ( OR) (95% CI) values of 0.915 (0.876-0.956), 0.875 (0.830-0.923) and 0.886 (0.848-0.927), respectively. The dose-response curve demonstrated that the negative association was primarily observed within the guideline-recommended optimal lipid level range. Specifically, when LDL-C was less than 3.4 mmol/L and non-HDL-C was less than 4.1 mmol/L, the corresponding OR (95% CI) values were 0.859 (0.796-0.926) and 0.876 (0.818-0.939). Conclusion:Lipid levels exhibit a certain linear negative association with cognitive impairment in elderly Chinese adults, with LDL-C and non-HDL-C demonstrating a stronger effect, particularly within the guideline-recommended optimal range.
