ObjectiveTo investigate the incidence and relevant factors of visual acuity abnormalities in preschool children undergoing kindergarten entrance physical examinations in Shannan City, Xizang, in 2022, so as to formulate policies for protecting children’s visual acuity and provide a basis for optimizing the children’s health service system in this region. MethodsA cross sectional study was conducted among the children undergoing kindergarten entrance physical examinations in Shannan City in 2022. A diopter examination was performed for these children, and a questionnaire survey was administered to their caregivers. Additionally, factors affecting children’s visual acuity abnormalities were analyzed using the χ² test and binary logistic regression analysis. ResultsA total of 759 children were included in the analysis, with an incidence rate for visual acuity abnormalities of 11.20%. Univariate analysis showed that statistically significant differences were observed in the incidence rate for visual acuity abnormalities among preschool children in terms of different family monthly income (χ²=17.395, P<0.001), father’s education level (χ²=5.133, P=0.023), postnatal vitamin A and D supplementation (χ²=9.575, P=0.008), and feeding method within the first 6 months after birth (χ²=9.330, P=0.009). Multivariate analysis results indicated that family monthly income <5 000 yuan (OR=2.599, P=0.003), insufficient postnatal vitamin A and D supplementation (OR=1.912, P=0.011), and formula feeding (OR=2.131, P=0.010) were relevant factors for abnormal visual development in children. ConclusionThe incidence of visual acuity abnormalities in preschool children in Shannan City is slightly higher than that previously reported in other regions of Xizang. The occurrence of visual acuity abnormalities in children is related to factors such as family monthly income, postnatal vitamin A and D supplementation, and feeding method within the first 6 months after birth. Future interventions should be strengthened on the promotion and dissemination of knowledge related to eye use, such as improve parental awareness of eye care, promote timely vitamin A and D supplementation and encourage breast feeding for children after birth, more specifically, attentions need to be focused on the visual acuity problems of children from low-income families to safeguard the visual health in preschool children in Shannan City, Xizang.

Objective:In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups.Results:There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant ( t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ2=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences ( Z=0.406, P=0.685). Conclusions:Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Alpha1-acid glycoprotein (AGP), also known as oral mucus protein (ORM), is an acute phase positive protein. AGPs have various biological activities, such as drug transport, immune regulation, maintenance of capillary barrier, regulation of lipid metabolism, etc. AGP mainly exists in liver cells, but it is also expressed in other tissue cells, such as adipose tissue, brain tissue, endothelial cells and immune cells. This article mainly reviews the application of AGP in pulmonary diseases, and the role,significance and related new developments in different systemic diseases.

Objective To evaluate the benefits of subcutaneous continuous glucose monitoring(SCGM)in blood glucose control of ICU patients,in order to open up the new ideas for blood glucose management in ICU patients.Methods The databases of PubMed,Cochrane Library,Embase,Web of Science,Wanfang,VIP,CNKI and China biomedical literature service system(SinoMed)were retrieved for the relevant randomized controlled trials(RCT)on SCGM in ICU patients from the establishment of the database to April 2024.The two researchers independently screened the literatures,extracted the data,and evaluated the risk of bias of the included studies by using Cochrane risk assessment tools.The Review manager5.4 was used for conducting the meta-analysis and the Stata16.0 was used for conducting the publication bias and sensitivity analysis.Re-sults Eighteen literatures were included,of which the quality evaluation of 17 literatures were the medium and included in the final study,1 literature was evaluated as low quality and was excluded from the analysis.A total of 1 799 research subjects,including the patients admitted to ICU after tumor and cardiac surgery,sepsis,oral space infection,acute pancreatitis,craniocerebral injury,etc,among them the diabetic patients accounted for 8.5％.The test group(SCGM)and control group(capillary glucose measurement by bedside glucometer or arterial glucose measurement by blood gas analyzer)showed a statistically significant in the incidence of hy-poglycemia(RR=0.35,95％CI:0.25-0.47,P＜0.001),mean blood glucose(SMD=-0.13,95％CI:-0.25 to-0.00,P=0.040),and the time proportion of glucose in the target range(SMD=0.29,95％CI:0.10-0.49,P=0.003);the insulin dosage subgroup analysis results showed that the insulin dosage between the two groups in the intensive insulin treatment group had no statistically significant difference(SMD=-0.44,95％CI:-1.05 to 0.17,P=0.160),but the insulin dosage between the two groups in the non-inten-sive insulin treatment group had statistically significant difference(SMD=-2.01,95％CI:-2.29 to-1.72,P＜0.001).Conclusion Compared with capillary glucose measurements by the bedside glucose me-ters or arterial glucose measurements by blood gas analyzers,using SCGM in ICU patients could reduce the in-cidence rate of hypoglycemia,insulin dosage and mean blood glucose,and improve the time proportion of glu-cose in the target range.

Objective:To investigate the correlation between psychological resilience and the risk of all-cause mortality in disabled older individuals.Methods:A total of 8, 089 disabled older adults were selected from the Chinese Longitudinal Healthy Longevity Survey(1998-2018)after screening with the Katz index.Psychological resilience was assessed at baseline using a seven-item self-rating scale.Participants were followed up until 2018, with survival data being recorded.Restricted cubic spline regression and Cox proportional hazard models were employed to analyze the association between psychological resilience and all-cause mortality, as well as to explore the potential interaction between psychological resilience and levels of disability.Results:After adjusting for potential confounding factors, a linearly negative relationship was found between levels of psychological resilience and mortality risk( P-nonlinear 0.781).Stratified analyses by degree of disability revealed that for older adults with mild disability, a 1 standard deviation increase in psychological resilience was associated with a 12% decrease in mortality risk( HR=0.88, 95% CI: 0.83-0.94).However, no significant association was observed between psychological resilience and mortality risk in severely disabled participants.A significant interaction was noted between resilience levels and degree of disability( P-interaction=0.026). Conclusions:This study offers observational evidence supporting the importance of maintaining psychological resilience in reducing mortality risk among disabled older individuals, particularly those with mild disability.The findings highlight the potential benefits of psychological interventions for older adults with varying levels of functional decline.

Objective:The study aims to investigate the relationship between the Geriatric Nutritional Risk Index(GNRI)and the risk of all-cause mortality in older adults living in the community.Methods:Using data from the Chinese Longitudinal Healthy Longevity Survey.a community-based population cohort study utilized the Geriatric Nutritional Risk Index(GNRI), which was calculated based on height, weight, and serum albumin levels during baseline surveys conducted in 2012 and 2014.Participants were categorized into normal(GNRI>98), mild malnutrition(92 ≤ GNRI ≤ 98), and moderate/severe malnutrition(GNRI<92)groups.Follow-up of all participants continued until 2018, during which data on death outcomes and survival time were gathered.The study employed Kaplan-Meier curves and Cox proportional hazards regression models to assess the relationship between GNRI levels and the risk of all-cause mortality.Results:A total of 3, 016 older adults were analyzed, with 1, 296(42.97%)identified as having malnutrition.Over a follow-up period of 10, 594.5 person-years, there were 1, 280 deaths recorded.Adjusting for various factors such as sociodemographic characteristics, functional abilities, cognitive function, and chronic diseases, the mild malnutrition group showed a hazard ratio( CI)of 1.35(95% CI: 1.18-1.56)compared to the normal group, while the moderate/severe malnutrition group had a HR of 1.85(95% CI: 1.61-2.12)for all-cause mortality risk.The GNRI's area under the ROC curve for predicting death was 0.70(95% CI: 0.61-0.77), with a sensitivity of 71.3% and specificity of 65.4%.Subgroup analysis revealed a more significant association between malnutrition and mortality risk in men compared to women( P-interaction=0.037). Conclusions:The findings suggest a notable link between malnutrition levels and the risk of all-cause mortality, indicating that GNRI could be a valuable tool for predicting survival outcomes in this population.

BACKGROUND:Many clinical research observations have indicated a close association between rheumatoid arthritis and osteoporosis as well as bone mineral density(BMD).However,it remains unclear whether there is a causal genetic relationship between rheumatoid arthritis and the development of osteoporosis and alterations of BMD. OBJECTIVE:To assess the potential causal relationship between rheumatoid arthritis and osteoporosis as well as BMD using a two-sample Mendelian randomization approach,provide meaningful insights from a genetic perspective into the underlying mechanisms and offer a reference for early prevention of osteoporosis and improvement in the progression of the disease. METHODS:We conducted a study using data from publicly available genome-wide association studies databases to identify single nucleotide polymorphisms associated with rheumatoid arthritis as instrumental variables(P＜5×10-8).The main outcomes of the study included osteoporosis and BMD at five different sites,including total body BMD,lumbar spine BMD,femoral neck BMD,heel BMD,and forearm BMD.The inverse variance-weighted method was used as the primary analysis method to evaluate causal effects.Weighted median,simple median,weighted mode and MR-Egger regression were used as supplementary analyses.Causal relationships between rheumatoid arthritis and the risk of osteoporosis and BMD were assessed using odds ratios(OR)and 95%confidence intervals(CI).Heterogeneity was assessed using Cochran's Q test and horizontal pleiotropy was evaluated using MR-Egger intercept tests. RESULTS AND CONCLUSION:The inverse variance-weighted analysis demonstrated a positive association between genetically predicted rheumatoid arthritis and osteoporosis(OR=1.123,95%CI:1.077-1.171;P=4.02×10-8).Heterogeneity test(P=0.388)indicated no significant heterogeneity among the single nucleotide polymorphisms.MR-Egger intercept(P=0.571)tests did not detect horizontal pleiotropy,and sensitivity analysis showed no evidence of bias in the study results.There was no causal relationship between rheumatoid arthritis and BMD at the five different sites.The total body BMD(OR=1.000,95%CI:0.988-1.012;P=0.925),lumbar spine BMD(OR=0.999,95%CI:0.982-1.016;P=0.937),femoral neck BMD(OR=1.001,95%CI:0.986-1.016;P=0.866),heel BMD(OR=0.996,95%CI:0.989-1.004;P=0.419),and forearm BMD(OR=1.063,95%CI:0.970-1.031;P=0.996)indicated no significant association.MR-Egger intercept analysis did not detect potential horizontal pleiotropy(total body BMD:P=0.253;lumbar spine BMD:P=0.638;femoral neck BMD:P=0.553;heel BMD:P=0.444;forearm BMD:P=0.079).Rheumatoid arthritis may contribute to the development of osteoporosis through the interaction between chronic inflammation and bone formation,resorption,and absorption.Additionally,the use of glucocorticoids and the presence of autoantibodies(such as anti-citrullinated protein antibody)in patients with rheumatoid arthritis showed associations with osteoporosis.Future research should focus on monitoring systemic inflammatory markers,standardized use of glucocorticoids,and regular screening for osteoporosis risk in patients with rheumatoid arthritis.

BACKGROUND:Recent studies have shown that the occurrence and prevention of osteoporosis often focus on the cellular molecular level,and the mechanism of related signaling pathways is an important way to further understand osteoporosis.At present,traditional Chinese medicine has been proved to play a significant role in alleviating osteoporosis.Kaempferol as an emerging Chinese herbal extract has become the focus of clinical and basic research due to its anti-osteoporosis effectiveness and mechanism of action. OBJECTIVE:To further understand the mechanism underlying the anti-osteoporosis effect of kaempferol active monomer through regulation of related signaling pathways by analyzing and collating domestic and foreign literature. METHODS:"Kaempferol,osteoporosis,osteoblasts,osteoclasts,bone marrow mesenchymal stem cells,signaling pathways"were used as Chinese and English search terms to search CNKI,WanFang,VIP,PubMed,Web of Science and Embase databases for relevant literature published from database inception to February 2023. RESULTS AND CONCLUSION:Kaempferol affects the occurrence and progression of osteoporosis to varying degrees by participating in the regulation of differentiation,proliferation and apoptosis of bone marrow mesenchymal stem cells,osteoblasts and osteoclasts.Kaempferol can prevent and treat osteoporosis by regulating various signaling pathways.Kaempferol can promote the proliferation and differentiation of osteoblasts and inhibit the formation of osteoclasts by interfering with the Wnt/β-catenin signaling pathway to regulate β-catenin protein counting and the formation of β-catenin-TCf/LEF complex.Kaempferol interferes with the RANK/RANKL pathway to maintain the dynamic balance of osteoclasts and bone homeostasis.Kaempferol can promote bone formation by intervening with the PI3K/Akt signaling pathway to upregulate the levels of related osteogenic factors Runx2 and Osterix and promote bone cell calcification.Kaempferol interferes with osteoclast differentiation and inhibits reactive oxygen species activity by regulating the ER/ERK pathway.Kaempferol inhibits the expression of ERK,JNK,p38/MAPK and decreases reactive oxygen species production by interfering with the MAPK pathway,thus protecting osteogenesis.Kaempferol enhances the expression of osteogenic factors,bone morphogenetic protein-2,p-Smad1/5/8,β-catenin and Runx2,inhibits the expression of Peroxisome proliferation-activated receptor,and promotes the differentiation and proliferation of osteoblasts through the BMP/Smad pathway.
