Sex difference in incidence of major depressive disorder: an analysis from the Global Burden of Disease Study 2019.

BACKGROUND: Major depressive disorder (MDD) is a leading mental disorder causing severe impairment. This study was aimed to evaluate sex difference in global MDD incidence by year, age, and socioeconomic status, according to the Global Burden of Disease Study 2019 (GBD 2019). METHODS: Global and national sex-specific incidence estimates of MDD, from 1990 to 2019, in different age groups, were extracted from the GBD 2019. Socioeconomic development index (SDI) as an indicator of national socioeconomic development was used. Absolute (female minus male) and relative (female to male ratio) sex difference in age-standardized incidence rates (ASRs), as well as risk ratios (RR and 95% confidence interval), were computed by year and age. Linear regression analyses were conducted to investigate socioeconomic-associated sex difference in incidence. RESULTS: Absolute and relative sex difference in ASRs showed a slight declining trend during 1990 and 2019, with absolute difference decreasing from 1818.23 to 1602.58, and relative difference decreasing from 1.71 to 1.61. Worldwide, females had a higher risk of MDD than males in 1990 (RR: 1.706 (1.705-1.706)) and 2019 (RR: 1.602 (1.619-1.620)). The highest RRs were observed in the Region of the Americas. Sex difference in incidence rates increased rapidly with age for those under 20 years old. The highest RR (1.913 (1.910-1.915)) was observed in the age group of 10-14. Relative sex difference had a significant positive relationship with SDI (standardized ß = 0.267, P < 0.001). CONCLUSIONS: Despite that slight improvement in sex difference in global MDD incidence has been achieved, sex difference still persists in the past decades, with females always having a higher incidence than males. Greater sex difference was found at younger ages and in more developed countries. The findings highlight the importance of making sex-specific health policy to reduce sex difference in MDD incidence.

Global patterns in vision loss burden due to vitamin A deficiency from 1990 to 2017.

OBJECTIVE: To investigate the vision loss burden due to vitamin A deficiency (VAD) at the global, regional and national levels by year, age, sex and socio-economic status using prevalence and years lived with disability (YLD). DESIGN: International, retrospective, comparative burden-of-disease study. SETTING: Prevalence and YLD data were extracted from the Global Burden of Disease (GBD) Study 2017. The association of age-standardised YLD rates and human development index (HDI) was tested by Pearson correlation and linear regression analyses. The Gini coefficient and concentration index (CI) were calculated to demonstrate the trends in between-country inequality in vision loss burden due to VAD. PARTICIPANTS: All participants met the GBD inclusion criteria. RESULTS: The age-standardised prevalence rate increased by 9·2 %, while the age-standardised YLD rates rose by 10·8 % from 1990 to 2017. Notably, the vision loss burden caused by VAD showed a declining trend since 2014. The vision loss burden was more concentrated in the post-neonatal age group and decreased with increasing age. The age-standardised YLD rates were inversely correlated with HDI (r = -0·2417, P = 0·0084). The CI and Gini coefficients indicated that socio-economic-related and between-country inequality declined from 2000 to 2017. VAD was the eighth leading cause of the age-standardised prevalence rate and ninth leading cause of age-standardised YLD rate among fifteen causes of vision loss in 2017. CONCLUSION: VAD has become one of the significant leading causes of vision loss globally. Efforts to control vision impairment related to VAD are needed, especially for children in countries with lower socio-economic status.

The effect of cold exposure on serum cholesterol is dependent upon ApoE.

BACKGROUND: Several lines of evidence indicate that cold stimulation may not only activate brown adipose tissue (BAT) and the white adipose tissue (WAT), but also regulate the lipid metabolism and influence the development of atherosclerosis. However, the study of cold exposure affecting cholesterol metabolism have opposite results in different experiments, and Apolipoprotein E (ApoE) may play an important role. There is still a lack of complete research to illustrate this problem. METHODS: In this study, we first analyzed and discussed the activation of interscapular brown adipose tissue (iBAT), inguinal white adipose tissue (iWAT) and epididymal white adipose tissue (eWAT) under cold exposure (4 °C) in male wild-type C57BL/6 J (WT) and ApoE-deficient mice (ApoE-/-) fed high-fat diet (HFD) for 4 weeks. Subsequently, we investigated the effect of cold exposure on blood lipid profiles in both models. We further explored whether cold exposure can reduce serum cholesterol. RESULTS: In both WT and ApoE-/- mice, cold exposure activates iBAT and iWAT, as well as hardly affects eWAT. In WT mice,4 weeks cold exposure (4 °C) reduces serum triglyceride by 28%, cholesterol by 30% and LDL-cholesterol by 63%. In ApoE-/- mice, cold stimulation decreases serum triglyceride by 59%, but increases cholesterol by 20% and LDL-cholesterol by 25%. CONCLUSIONS: Based on these findings, we conclude that cold exposure decreases serum cholesterol is dependent upon the existence of ApoE.

Eye diseases burden in China in the past 30 years.

To investigate the national burden of eye diseases in China from 1990 to 2019. The national burden of eye diseases in China, including case numbers, prevalence rate, age-standardized prevalence rate (ASR), disability-adjusted life year (DALY), DALY rate and age-standardized DALY rate (ASD) were calculated and stratified by sex and age. The trends of eye diseases burden from 1990 to 2019 and the correlation between eye diseases burden and human development index (HDI) were analyzed. In 2019, the total case number of eye diseases in China was 0.21 billion, the ASR was 9511/10, the total number of DALY was 4.72 million, and the ASD was 247.4/10. Near vision loss caused the greatest burden, followed by refraction disorders and cataract, with ASD being 73.8/10, 70.3/10 and 59.2/10, respectively. Men had lower risks of eye diseases than women. People aged old and old had the greatest burden of eye diseases. Compared with the year 1990, the total case number increased by 134.6% and DALY by 113.0% in 2019. The ASD of all decreased by 7.5%, and was negatively correlated with national HDI. Near vision loss, refraction disorders and cataract are of heavy disease burden in China. Although the ASD of eye diseases is decreased with the development of the national socioeconomic status, the eye diseases burden in China still increased with population growth and aging.

Incidence and risk of ptosis following ocular surgery: a systematic review and meta-analysis.

OBJECTIVE: We conducted a systematic review and meta-analysis to evaluate the incidence and risk factors of ptosis following ocular surgery. METHODS: PubMed, Embase, and Cochrane Library were searched for articles that assessed the incidence or risk factors of ptosis following ocular surgery up to October 2017. We used a fixed effects model to calculate a pooled estimate of incidence, with subgroup analyses to evaluate the effect of different variables. The relative risks (RRs) or odds ratios (ORs) and 95% confidence intervals (CIs) for all available factors were calculated using the fixed effects models. RESULTS: A total of 16 studies on 2856 eyes were analyzed, including 3 randomized controlled trials (RCTs) and 13 cohort studies. The overall incidence of ptosis following ocular surgery was 11.4% (95% CI 10.1-12.8%). Subgroup analyses showed that the region and the surgery type were significantly associated with the incidence of postoperative ptosis. Men were less likely to get postoperative ptosis than women (OR 0.62; 95% CI 0.43-0.89). However, age (OR 0.77; 95% CI 0.48-1.23), side (OR 1.37; 95% CI 0.84-2.25), type of anesthesia (OR 0.57; 95% CI 0.16-2.05), prior surgery (OR 1.09; 95% CI 0.64-1.83), bridle suture (OR 2.04; 95% CI 0.94-4.42), or combined surgery (OR 0.95; 95% CI 0.58-1.57) did not significantly change the risk of ptosis following ocular surgery. CONCLUSION: More than one in ten patients who undergo ocular surgery will develop ptosis. Different regions and surgery types may influence the occurrence of this abnormality. Female gender is a risk factor for development of postoperative ptosis.

[Huotan Jiedu Tongluo decoction alleviates early atherosclerosis of rabbits by inhibiting eNOS uncoupling pathway].

The aim of this paper was to study the curative effect of Huotan Jiedu Tongluo (HTJDTL) decoction on a rabbit model with early atherosclerosis (AS),and furtherly to explore whether it could inhibit the BH4/eNOS uncoupling ROS or not. Twenty-four Japanese white rabbits were randomly divided into sham operation group, model group, HTJDTL decoction group and atorvastatin group. Rabbit models with early atherosclerosis were established by high fat diet, nitrogen drying and carotid artery balloon injury. The rabbits were sacrificed at 7th days after balloon injury and several parameters were measured. The pathological morphology of the common carotid artery was observed by HE staining. The blood lipids were detected by peroxidase method. The ratio of vascular eNOS dimer and monomer was measured by Western blot. The ELISA and biochemical technology were respectively used for testing BH4 and ROS levels in serum. The results showed that compared with the sham operation group, the model group had mild stenosis of the common carotid artery lumen, uneven intimal hyperplasia, lipid deposition in the intima and media, and obvious hyperplasia of the adventitia with inflammatory cell infiltration. The HTJDTL decoction could significantly inhibit the intimal hyperplasia compared with the model group, meanwhile, reduce the lipid deposition of the media and the infiltration of the adventitial cells. Compared with the sham operation group, the blood lipids and ROS of the model animals significantly increased, but BH4 and the ratio of eNOS dimer/monomer decreased. Compared with the model group, HTJDTL decoction significantly reduced the TC, ox-LDL and ROS levels, and also up-regulated eNOS dimer/monomer ratio, but it increased BH4 trend without statistical difference. According to the results, it was found that HTJDTL decoction couldsignificantly prevent and improve the vascular remodeling of rabbits model with early atherosclerosis. The mechanism of decoction may largely be related to the inhibition of BH4/eNOS uncoupling and the reduction of oxidative stress.

Panax notoginseng saponins administration modulates pro- /anti-inflammatory factor expression and improves neurologic outcome following permanent MCAO in rats.

Ischemic stroke, particularly permanent occlusion, accounts for the overwhelming majority of all strokes. In addition to the occlusion of arteries, the inflammatory response plays a pivotal role in the severity of the cerebral injury and its clinical prognosis. Here, panax notoginseng saponins (PNS) extracted from a traditional Chinese herbal medicine was administered following permanent middle cerebral artery occlusion (MCAO) in rats to explore the neuroprotective mechanisms against ischemic injury. The results showed that MCAO surgery was successful in producing an infarct and that PNS and nimodipine could ameliorate the neurological deficits. The expression levels of interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α) and transforming growth factor-ß1 (TGF-ß1) were increased, while the level of interleukin-10 (IL-10) was reduced in the infarct cortex 7 days after MCAO, as assessed by immunohistochemistry, western blotting and quantitative real-time PCR (qRT-PCR). PNS was able to markedly reduce the overexpression of IL-1ß and TNF-α while significantly promoting the expression of IL-10, but did not affect the elevated expression of TGF-ß1. Meanwhile, nimodipine was able to significantly reduce the expression of IL-1ß and TNF-α, but had no obvious effect on IL-10 or TGF-ß1. In addition, the serum levels of TNF-α, IL-10 and TGF-ß1 were basically consistent with cerebral tissue results; however, the IL-1ß levels did not differ. We conclude that PNS can directly down-regulate the overexpression of proinflammatory factors IL-1ß and TNF-α while up-regulating the expression of anti-inflammatory factor IL-10 in the core region of the cerebral infarct, thereby preventing neurological damage in rats after permanent MCAO.

Herbal formula Xian-Fang-Huo-Ming-Yin regulates differentiation of lymphocytes and production of pro-inflammatory cytokines in collagen-induced arthritis mice.

BACKGROUND: Xian-Fang-Huo-Ming-Yin (XFHM), a traditional herbal formula, has been used to treat sores and carbuncles for hundreds of years in Asia. Nowadays, its clinical effects in treatment of rheumatoid arthritis (RA) have been validated. In this study, we want to study its possible molecular mechanisms of regulating the differentiation of lymphocytes and production of pro-inflammatory cytokines in collagen-induced arthritis (CIA) mice for RA treatment. METHODS: A high performance liquid chromatography-electrospray ionization/mass spectrometer (HPLC-ESI/MSn) system was used to analyze the constituents of XFHM granules. An arthritics mouse model was induced by collagen and leflunomide (LEF) was used as a positive control medicine. Pathological changes at the metatarsophalangeal joint were studied through Safranin O and immunohistochemical staining. The differentiation of T, B and NK cells was examined by flow cytometry and pro-inflammatory cytokines were assayed using an Inflammation Antibody Array assay. The expression of key molecules of the nuclear factor κB (NF-κB) and Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathways in spleen were studied by western-blot analysis. RESULTS: In our study. 21 different dominant chemical constituents were identified in XFHM. Treatment with XFHM suppressed the pathological changes in arthrosis of CIA. Additionally, XFHM down-regulated the proliferation and differentiation of CD3+ T cells and CD3-CD19+ B cells significantly. However, XFHM had no significant effect on CD3-NK1.1+ NK cells. Further study showed that the production of pro-inflammatory cytokines had been suppressed by inhibiting the activation of NF-κB and JAK/STAT signaling. CONCLUSIONS: XFHM can regulate and maintain the immunologic balance of lymphocytic immunity and inhibit the production of pro-inflammatory cytokines, thus suppressing the pathological changes of RA. Therefore, XFHM may be used as an application of traditional medicine against RA in modern complementary and alternative therapeutics.

Chlorogenic acid and luteolin synergistically inhibit the proliferation of interleukin-1ß-induced fibroblast-like synoviocytes through regulating the activation of NF-κB and JAK/STAT-signaling pathways.

CONTEXT: Chlorogenic acid (CGA) and luteolin (Lut) are the predominant constituents of Caulis Lonicerae, which is usually used in the treatment for rheumatoid arthritis (RA). OBJECTIVE: In this study, we investigated whether CGA and Lut could synergistically inhibit the proliferation of fibroblast-like synoviocytes (FLSs) in RA synovial tissues. METHODS: Rat FLS cells (RSC-364) induced by interleukin (IL)-1ß were treated by CGA, Lut or both of them. The apoptosis rates were detected by flow cytometer. Protein expression of key molecules of NF-κB and JAK/STAT signaling pathways were detected by Western blot. RESULTS AND DISCUSSION: Treatment with CGA and Lut inhibited the proliferation of RSC-364 cells stimulated by IL-1ß significantly and induced cell apoptosis notably. The ratio of apoptosis in RSC-364 cells induced with IL-1ß accompanied by both CGA and Lut increased approximately 7-fold compared with those incubated with IL-1ß alone. The results of immunoblot analysis revealed that the key molecules involved in the NF-κB and JAK/STAT-signaling pathways, including NF-κB p50, p100, IKKα/ß, gp103, JAK1 and STAT3, were decreased significantly in RSC-364 cells treated by IL-1ß plus CAG and Lut compared with those incubated with IL-1ß alone. Additionally, the amounts of phospho-IKKα/ß and phospho-STAT3 were also decreased significantly in cells treated with CGA and Lut. Furthermore, the synergistic effect of CGA and Lut was superior to the effect of one of these two ingredients. CONCLUSION: Our finding suggested that the combination of CGA and Lut may be a potential therapeutic treatment for the inflammatory proliferation of synoviocytes in patients with RA.

[Effect of Yishen Daluo Decoction on the expression of PLP, Olig1, and Olig2 in mice with experimental autoimmune encephalomyelitis].

OBJECTIVE: To study the effect of Yishen Daluo Decoction (YDD) on the expression of protein lipoprotein (PLP), oligodendrocyte transcription factor 1 (Olig 1), and oligodendrocyte transcription factor 2 (Olig2) in mice with experimental autoimmune encephalomyelitis (EAE). METHODS: Totally 40 mice were randomly divided into 4 groups, i.e., the normal group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 mice in each group. Each mouse in the model, CM, and WM groups was subcutaneously injected with 200 microL antigen emulsion (containing 150 micro g PLP139 -151 and 400 micro g H37RA) in two parts at the upper abdomen on the first day. 100 microLBordetella pertussis juice (containing 0. 6 x 10(6) Bordetella pertussis) was injected by caudal vein on the first and the third day. On the 7th day after modeling, each mouse in the normal group and the model group was intragastrically given normal saline (0. 1 mL/10 g). YDD (0. 2 g crude drug/10 g) was intragastrically given to mice in the CM group, and prednisone (0. 039 mg/10 g) was intragastrically given to mice in the WM group. All mice were intervened for 54 days. Changes of PLP, Olig1, and Olig2 in the brain tissue of EAE mice were detected by Western blot. Results The levels of PLP and Olig2 in the brain tissue of the model group were less than those of the normal group (P <0.05). Compared with the model group, the levels of PLP, Olig1, and Olig2 in the brain tissue increased in the CM group (P <0.05); the levels of PLP and Olig2 in the brain tissue increased in the WM group (P <0.05). Compared with the WM group, the level of Olig1 in the brain tissue increased in the CM group (P <0.05). CONCLUSION: YDD could enhance remyelination by elevating the levels of Olig1 and Olig2 in the brain tissue of EAE mice.

Gender Disparities in the Global Burden of Refractive Disorders in Children: An Analysis From the Global Burden of Disease Study 2019.

PURPOSE: To investigate gender disparities in the global burden of refractive disorders in children younger than 15 years by year, age, and national developmental status using disability-adjusted life years (DALYs). METHODS: Global, regional, and national gender-specific DALY numbers and rates of refractive disorders in children were obtained by year (from 1990 to 2019) and age group (0 to 4, 5 to 9, and 10 to 14 years) from the Global Burden of Disease Study 2019. Data from the Inequality-adjusted Human Development Index in 2019 as an indicator of national developmental status were extracted from the Human Development Report. Pearson correlation and linear regression analyses were performed to explore the association between female-to-male DALY rate ratios and national developmental status. RESULTS: Gender disparities in DALY numbers and rates of refractive disorders in children have persisted and shown little improvement from 1990 to 2019. Girls had a higher burden than boys of the same age, and gender disparities increased with age (1.120 in preschool children aged 0 to 4 years, 1.124 in younger school-aged children aged 5 to 9 years, and 1.135 in older school-aged children aged 10 to 14 years). Female-to-male DALY rate ratios were negatively related to Inequality-adjusted Human Development Index values (standardized b = -0.189, P < .05). CONCLUSIONS: Gender disparities in the global burden of refractive disorders in children have persisted for decades, with girls who are older and from lower-income countries having a higher burden than boys. Gender-specific health policies should be made to manage refractive disorders in children. [J Pediatr Ophthalmol Strabismus. 2024;61(1):51-58.].

Automatic Measurement and Comparison of Normal Eyelid Contour by Age and Gender Using Image-Based Deep Learning.

Purpose: This study aimed to propose a fully automatic eyelid measurement system and compare the contours of both the upper and lower eyelids of normal individuals according to age and gender. Design: Prospective study. Participants: Five hundred and forty healthy Chinese aged 0 to 79 years in a tertiary hospital were included. Methods: Facial images in the primary gazing position were used to train and test the proposed automatic system for eye recognition and eye segmentation. According to the 10-millimeter diameter circular marker, measurements were transformed from pixel sizes into factual distances. Main Outcome Measures: Midpupil lid distances (MPLDs) every 15° of all participants were automatically measured in both genders (30 males and 30 females in each age group) by the proposed deep learning (DL)-based system. Intraclass correlation coefficients (ICCs) were performed to assess the agreement between the automatic and manual margin reflex distances (MRDs). The eyelid contour, eyelid asymmetry, and palpebral fissure obliquity were analyzed using MPLD, temporal-versus-nasal MPLD ratio, and the angle between the inner and outer canthi, respectively. Results: The measurement of MRDs by the automatic system excellently agreed with that of the expert, with ICCs ranging from 0.863 to 0.886. As the age of the participants increased, the values of MPLDs reached a peak in those in their 20s or 30s and then gradually decreased at all angles. The temporal sector showed greater changes in MPLDs than the nasal sector, and the changes were more significant in females than in males. The maximum value of palpebral fissure obliquity appeared before 10 years in both genders and remained relatively stable after the 20s (P > 0.05). Conclusions: The proposed DL-based eyelid analysis system allowed automatic, accurate, and comprehensive measurement of the eyelid contour. The refinement of eyelid shape quantification could be beneficial for future objective assessment preocular and postocular plastic surgery.

Application of artificial intelligence in oculoplastics.

Oculoplastics is a subspecialty of ophthalmology/dermatology concerned with eyelid, orbital, and lacrimal diseases. Artificial intelligence (AI), with its powerful ability to analyze large data sets, has dramatically benefited oculoplastics. The cutting-edge AI technology is widely applied to extract ocular parameters and to use these results for further assessment, such as screening and diagnosis of blepharoptosis and predicting the progression of thyroid eye disease. AI also assists in treatment procedures, such as surgical strategy planning in blepharoptosis. High efficiency and high reliability are the most apparent advantages of AI, with promising prospects. The possibilities of AI in oculoplastics may lie in three-dimensional modeling technology and image generation. We retrospectively summarize AI applications involving eyelid, orbital, and lacrimal diseases in oculoplastics, and we also examine the strengths and weaknesses of AI technology in oculoplastics.

Evaluation and application of a Chinese version symptom questionnaire for visual dysfunctions (CSQVD) in school-age children.

Objective: To develop and evaluate a Chinese version of the Symptom Questionnaire for Visual Dysfunctions (CSQVD) to quantify visual dysfunction symptoms in school-age children with various eye diseases, and to explore the relationship between ophthalmological disorders and visual dysfunction symptoms. Methods: Following standard scale adaptation procedures, the Symptom Questionnaire for Visual Dysfunctions (SQVD) was translated into Chinese (CSQVD). We employed random sampling to survey 198 outpatients aged 7-18 to assess the psychometric properties of the CSQVD. Using the reliable and validated questionnaire, we evaluated the determinants of visual dysfunction symptoms among 406 school-age patients at an eye center. The CSQVD scores were correlated with demographic and clinical variables, including gender, age, eye position, refractive power, and best-corrected visual acuity. Univariate analysis identified potential risk factors, followed by binary logistic regression and multiple linear regression analysis on factors with a P-value <0.05. Results: The CSQVD scale's critical ratio (CR) values ranged from 6.028 to 10.604. The Cronbach's Alpha coefficient was 0.779, and Spearman-Brown split-half reliability was also 0.779. The I-CVI varied from 0.83 to 1.000, the S-CVI/Ave was 0.857, and the KMO value was 0.821. Multifactorial regression analysis indicated that high myopia (OR â€‹= â€‹5.744, 95% CI [1.632, 20.218], P â€‹= â€‹0.006) and amblyopia (OR â€‹= â€‹9.302, 95% CI [1.878, 46.058], P â€‹= â€‹0.006) were significant predictors of CSQVD symptoms. Multiple linear regression analysis showed that BCVA of amblyopic eyes (B â€‹= â€‹-5.052, 95% CI [-7.779, 2.325], P â€‹= â€‹0.000) and SE power (B â€‹= â€‹-0.234, 95% CI [-0.375, 0.205], P â€‹= â€‹0.001) significantly affected the CSQVD scale scores. Conclusions: The Chinese version of the SQVD scale (CSQVD) demonstrates good feasibility, discriminatory power, validity, and reliability in assessing Chinese school-aged children. Furthermore, those who have severe myopia and amblyopia reported more visual dysfunction symptoms.

Transcriptomic analysis reveals the critical role of chemokine signaling in the anti-atherosclerosis effect of Xuefu Zhuyu decoction.

ETHNOPHARMACOLOGICAL RELEVANCE: The process of atherosclerosis (AS) is complicated. Transcriptomics technology can assist in discovering the underlying mechanisms and exploring the key targets of Traditional Chinese Medicine (TCM) against atherosclerosis. AIM: This study aimed to investigate targets and signaling pathways significantly related to AS and the potential intervention targets of Xuefu Zhuyu decoction by transcriptomics. MATERIALS AND METHODS: AS models were established by subjecting ApoE-/-mice to an 8-week high-fat diet. Structural changes and plaque formation in the aortic root were observed using hematoxylin-eosin staining (HE staining), while Oil Red O staining was employed to visualize lipid deposition within the aortic root plaque. Movat staining and immunohistochemical staining were conducted to examine the components present in the aortic root plaque. Macrophage content within the plaque was observed through immunofluorescence. Additionally, mRNA sequencing was performed on aortic tissues to identify differentially expressed genes. Enrichment analysis was performed using GO and KEGG analysis. Visualization of the protein-protein interaction (PPI) network was achieved using Cytoscape 3.7.1 and STRING. Western blotting (WB) was employed to assess the protein expression of major differentially expressed genes in the aortic tissue. The drug freeze-dried powder of Xuefu Zhuyu decoction was prepared and the RAW264.7 cells were induced by lipopolysaccharide (LPS) to build an in vitro model. Real-time quantitative PCR was employed to measure the mRNA expression of major differential genes. RESULTS: After ApoE-/- mice were fed with an 8-week high-fat diet, observable changes included the thinning of the aortic root wall, the accumulation of foam cells within the plaque, and the formation of cholesterol crystals in the model group. Treatment with Xuefu Zhuyu (XFZY) decoction for 12 weeks significantly reduced the lipid deposition and the number of macrophages (P < 0.05) and significantly increased the collagen content within the plaque (P < 0.01). Enrichment analysis revealed a high enrichment of the Cytokine-cytokine receptor interaction pathway and Chemokine signaling pathway. Noteworthy genes involved in this response included Ccl12, Ccl22, Cx3cr1, Ccr7, Ccr2, Tnfrsf25, and Gdf5. Xuefu Zhuyu decoction significantly downregulated the expression of CX3CL1 and CX3CR1 (P < 0.05) and upregulated the expression of GDF5 (P < 0.01). Compared with control group, in cell models, the mRNA expressions of Ccl12, Ccl22, and Ccr2 were significantly upregulated (P < 0.05 or P < 0.01). Xuefu Zhuyu decoction significantly downregulated the expression of Ccl12, Ccl22, Cx3cr1, Ccr7 and Ccr2 (P < 0.05 or P < 0.01). CONCLUSION: Xuefu Zhuyu decoction demonstrates effective regulation of plaque components, retarding plaque progression and preserving plaque stability by modulating lipid metabolism and inflammatory responses. Subsequent transcriptome analysis identified the Cytokine-cytokine receptor interaction and Chemokine signaling pathway as potential key pathways for the therapeutic effects of Xuefu Zhuyu decoction. This insight not only provides crucial avenues for further exploration into the mechanisms underlying Xuefu Zhuyu decoction but also offers valuable perspectives and hypotheses for enhancing disease prevention and treatment strategies.

Mechanism of Qili Qiangxin Capsule for Heart Failure Based on miR133a-Endoplasmic Reticulum Stress.

OBJECTIVE: To investigate the pharmacological mechanism of Qili Qiangxin Capsule (QLQX) improvement of heart failure (HF) based on miR133a-endoplasmic reticulum stress (ERS) pathway. METHODS: A left coronary artery ligation-induced HF after myocardial infarction model was used in this study. Rats were randomly assigned to the sham group, the model group, the QLQX group [0.32 g/(kg·d)], and the captopril group [2.25 mg/(kg·d)], 15 rats per group, followed by 4 weeks of medication. Cardiac function such as left ventricular ejection fraction (EF), fractional shortening (FS), left ventricular systolic pressure (LVSP), left ventricular end diastolic pressure (LVEDP), the maximal rate of increase of left ventricular pressure (+dp/dt max), and the maximal rate of decrease of left ventricular pressure (-dp/dt max) were monitored by echocardiography and hemodynamics. Hematoxylin and eosin (HE) and Masson stainings were used to visualize pathological changes in myocardial tissue. The mRNA expression of miR133a, glucose-regulated protein78 (GRP78), inositol-requiring enzyme 1 (IRE1), activating transcription factor 6 (ATF6), X-box binding protein1 (XBP1), C/EBP homologous protein (CHOP) and Caspase 12 were detected by RT-PCR. The protein expression of GRP78, p-IRE1/IRE1 ratio, cleaved-ATF6, XBP1-s (the spliced form of XBP1), CHOP and Caspase 12 were detected by Western blot. TdT-mediated dUTP nick-end labeling (TUNEL) staining was used to detect the rate of apoptosis. RESULTS: QLQX significantly improved cardiac function as evidenced by increased EF, FS, LVSP, +dp/dt max, -dp/dt max, and decreased LVEDP (P<0.05, P<0.01). HE staining showed that QLQX ameliorated cardiac pathologic damage to some extent. Masson staining indicated that QLQX significantly reduced collagen volume fraction in myocardial tissue (P<0.01). Results from RT-PCR and Western blot showed that QLQX significantly increased the expression of miR133a and inhibited the mRNA expressions of GRP78, IRE1, ATF6 and XBP1, as well as decreased the protein expressions of GRP78, cleaved-ATF6 and XBP1-s and decreased p-IRE1/IRE1 ratio (P<0.05, P<0.01). Further studies showed that QLQX significantly reduced the expression of CHOP and Caspase12, resulting in a significant reduction in apoptosis rate (P<0.05, P<0.01). CONCLUSION: The pharmacological mechanism of QLQX in improving HF is partly attributed to its regulatory effect on the miR133a-IRE1/XBP1 pathway.

Acteoside delays the fibrosis process of diabetic nephropathy by anti-oxidation and regulating the autophagy-lysosome pathway.

Renal fibrosis is the final pathological change of kidney disease, it has also been recognized to be critical for the final progression of diabetic nephropathy (DN) to kidney failure. Acteoside (ACT) is a phenylethanoid glycoside widely distributed in dicotyledonous plants. It has many pharmacological activities, such as anti-oxidation, anti-inflammation, anti-cancer, neuroprotection, cardiovascular protection, anti-diabetes, bone and cartilage protection, liver and kidney protection, and antibacterial activity. This study aims to investigate the protective effects of ACT on renal interstitial fibrosis in rats with DN induced by intraperitoneal injection of streptozocin (STZ) combined with unilateral nephrectomy and its mechanism. In vivo and in vitro, the effects of ACT on reactive oxygen species (ROS) level, oxidative tubular injury, as well as damage of autophagic flux and lysosome in the DN model were detected. Results indicate that administration of ACT delayed the progression of renal interstitial fibrosis in DN by anti-oxidation and regulating the autophagy-lysosome pathway, which may potentially be attributed to the regulatory influence of ACT on transcription factor EB (TFEB).

Physical appearance perfectionism in blepharoplasty patients: A prospective observational study.

BACKGROUND: Evaluation of physical appearance perfectionism (PAP) in individuals seeking blepharoplasty would be meaningful. This study aimed to explore the relationship of demographic and psychological variables with PAP in blepharoplasty patients and further investigate the impact of blepharoplasty on PAP in these patients. METHODS: This prospective observational study included 153 patients undergoing blepharoplasty between October 2017 and June 2019. Demographic and psychological variables, and PAP, were collected preoperatively. Postoperative satisfaction with eye appearance and PAP was collected with a 6-month follow-up. RESULTS: Partial correlations analyses revealed that hope for perfection was positively associated with self-esteem (r = 0.246; P < 0.01) in 153 blepharoplasty patients. Worry about imperfection was positively related to facial appearance concern (r = 0.703; P < 0.001) and negatively related to satisfaction with eye appearance (r = -0.242; P < 0.01) and self-esteem (r = -0.533; P < 0.001). After blepharoplasty, the mean± standard deviation of satisfaction with eye appearance increased (preoperatively vs. postoperatively: 5.1 ± 2.2 vs. 7.4 ± 2.2; P < 0.001), and worry about imperfection decreased (17.0 ± 4.2 vs. 15.9 ± 4.6; P < 0.001). Whereas hope for perfection remained unchanged (23.9 ± 3.9 vs. 23.6 ± 3.9; P > 0.05). CONCLUSIONS: Appearance perfectionism was related to psychological variables rather than demographic variables in blepharoplasty patients. Preoperative evaluation of appearance perfectionism could be helpful for oculoplastic surgeons to screen for perfectionistic patients. Although some improvement in perfectionism has been observed after blepharoplasty, long-term follow-up is needed in the future.

Global research of artificial intelligence in strabismus: a bibliometric analysis.

Purpose: To analyze the global publications on artificial intelligence (AI) in strabismus using a bibliometric approach. Methods: The Web of Science Core Collection (WoSCC) database was used to retrieve all of the publications on AI in strabismus from 2002 to 2023. We analyzed the publication and citation trend and identified highly-cited articles, prolific countries, institutions, authors and journals, relevant research domains and keywords. VOSviewer (software) and Bibliometrix (package) were used for data analysis and visualization. Results: By analyzing a total of 146 relevant publications, this study found an overall increasing trend in the number of annual publications and citations in the last decade. USA was the most productive country with the closest international cooperation. The top 3 research domains were Ophthalmology, Engineering Biomedical and Optics. Journal of AAPOS was the most productive journal in this field. The keywords analysis showed that "deep learning" and "machine learning" may be the hotspots in the future. Conclusion: In recent years, research on the application of AI in strabismus has made remarkable progress. The future trends will be toward optimized technology and algorithms. Our findings help researchers better understand the development of this field and provide valuable clues for future research directions.

Diagnosing Systemic Disorders with AI Algorithms Based on Ocular Images.

The advent of artificial intelligence (AI), especially the state-of-the-art deep learning frameworks, has begun a silent revolution in all medical subfields, including ophthalmology. Due to their specific microvascular and neural structures, the eyes are anatomically associated with the rest of the body. Hence, ocular image-based AI technology may be a useful alternative or additional screening strategy for systemic diseases, especially where resources are scarce. This review summarizes the current applications of AI related to the prediction of systemic diseases from multimodal ocular images, including cardiovascular diseases, dementia, chronic kidney diseases, and anemia. Finally, we also discuss the current predicaments and future directions of these applications.
