Curative Effect Analysis of Zoledronic Acid in the Treatment of Postmenopausal Osteoporosis with Different Bone Turnover Rates

Objective: To explore the clinical efficacy of Zoledronic Acid Injection in the treatment of postmenopausal osteoporosis with different bone turnover rates. Methods: A total of 63 patients diagnosed with postmenopausal osteoporosis were included in this study. Each patient was administrated 5 mg/100mL Zoledronic Acid (Aclasta) intravenously once and then given a one-year prescription of 600 mg/d oral Caltrate. The bone turnover parameters (PINP, β-cross, N-MID) were measured prior to the injection of Zoledronic Acid while the bone mineral density (BMD) and the pain scores of each patient were tested before treatment and after the one-year medication. On this basis, the patients were divided into several groups according to their bone turnover rates for intergroup comparison of treatment outcomes. Results: BMD results and pain scores of all participants were significantly improved at different levels after treatment. However, these improvements had no significant differences between the patients with high and low bone turnover rates. Conclusion: Zoledronic Acid Injection can relieve bone pain, enhance the quality of life and increase the BMD in patients with postmenopausal osteoporosis, regardless of the bone turnover status.

The Role of Health Education in Improving Patient Compliance with Zoledronic Acid

Objective: To define the role of health education in improving patient compliance with Zoledronic Acid for osteoporosis treatment and management and draw closer attention of patients and physicians to the importance of health education. Methods: A total of 198 postmenopausal patients with osteoporosis who were admitted by the osteoporosis outpatient clinic of our hospital and had the first administration of Zoledronic Acid in 2015 were invited to participate in the follow-up visit that involved questions concerning the frequency of health education and the questionnaire survey on osteoporosis in 2015 and the administration of Zoledronic Acid during the past three years. The patients were divided into five groups according to the frequency of health education to compare the survey results of each group in 2015 and 2018 and investigate the differences in the scores and frequency of administration among the five groups. Results: Among the 198 patients, there were 182 attending the follow-up visit. In terms of the frequency of health education (FREQ = 0, 1, 2, 3, 4), these patients were divided into five groups of 47, 63, 35, 18 and 19 members respectively. After three years of treatment, the questionnaire score of each group was higher than the pre-treatment level and the difference showed statistical significance (p Conclusion: Health education is an effective approach to influence a patient’s knowledge connected to relevant diseases in a positive way and improve patient compliance with Zoledronic Acid treatment. An enhanced health education program can be developed to assist the patients in chronic disease management.

The Handan Offspring Myopia Study

The Handan Offspring Myopia Study(HOMS),whose participants came from 6 villages where all people aged≥30 years had taken part in the Handan Eye Study(HES)in 2006-2007,was designed to obtain the familial associations of myopia between parents and their offspring.From March 2010 to June 2010,of 1,238 eligible individuals,878 children(70.2%;52.6%male)from 541 families were recruited.The mean age of the children was 10.5±2.5 years.All the participants had a detailed eye examination and anthropometry examination.All examinations were performed using the same protocols and equipment in both HES and HOMS.Information of the parents was obtained from the HES.The results of the research showed that the myopic shift from parents to children was estimated to be approximately 1 D at 18 years of age.For near work and myopia,no association was found,except for the high near work subgroup with moderate outdoor activity levels.Besides a weak protective effect of outdoor activity on myopia in these rural children was observed.In the future,we plan to follow up these participants and investigate how the refraction of the children change,how myopia-genic activity changes and what effect does it have on myopia.The information will be important for the design of strategies to prevent and reduce myopia.

Identification and validation of key biomarkers and potential therapeutic targets for primary open-angle glaucoma

Primary open-angle glaucoma(POAG)is a prevalent cause of blindness worldwide,resulting in degeneration of retinal ganglion cells and permanent damage to the optic nerve.However,the underlying pathogenetic mechanisms of POAG are currently indistinct,and there has been no effective nonsurgical treatment regimen.The objective of this study is to identify novel biomarkers and potential therapeutic targets for POAG.The mRNA expression microarray datasets GSE27276 and GSE138125,as well as the single-cell high-throughput RNA sequencing(sc RNA-seq)dataset GSE148371 were utilized to screen POAGrelated differentially expressed genes(DEGs).Functional enrichment analyses,protein-protein interaction(PPI)analysis,and weighted gene co-expression network analysis(WGCNA)of the DEGs were performed.Subsequently,the hub genes were validated at a single-cell level,where trabecular cells were annotated,and the mRNA expression levels of target genes in different cell clusters were analyzed.Immunofluorescence and quantitative real-time PCR(q PCR)were performed for further validation.DEGs analysis identified 43 downregulated and 32 upregulated genes in POAG,which were mainly enriched in immune-related pathways,oxidative stress,and endoplasmic reticulum(ER)stress.PPI networks showed that FN1 and DUSP1 were the central hub nodes,while GPX3 and VAV3 were screened out as hub genes through WGCNA and subsequently validated by q PCR.Finally,FN1,GPX3,and VAV3 were determined to be pivotal core genes via single-cell validation.The relevant biomarkers involved in the pathogenesis of POAG,may serve as potential therapeutic targets.Further studies are necessary to unveil the mechanisms underlying the expression variations of these genes in POAG.

New loci for refractive errors and ocular biometric parameters in young Chinese Han adults

Myopia has become a major public health issue with an increasing prevalence.There are still individuals who experience similar environmental risk factors and,yet,remain non-myopic.Thus,there might be genetic factors protecting people from myopia.Considering the opposite ocular characteristics of primary angle closure glaucoma(PACG)to myopia and possible common pathway between them,we propose that certain risk genes for PACG might act as a protective factor for myopia.In this study,2,678 young adults were genotyped for 37 targeted single nucleotide polymorphisms.Compared with emmetropia,rs1401999(allele C:OR=0.795,P=0.03;genotype in dominant model:OR=0.759,P=0.02)and rs1258267(allele A:OR=0.824,P=0.03;genotype in dominant model:OR=0.603,P=0.01)were associated with low to moderate myopia and high myopia,respectively.Genotype under recessive model of rs11024102 was correlated with myopia(OR=1.456,P=0.01),low to moderate myopia(OR=1.443,P=0.02)and high myopia(OR=1.453,P=0.02).However,these associations did not survive Bonferroni correction.Moreover,rs1401999,rs1258267,and rs11024102 showed associations with certain ocular biometric parameters in different groups.Our study suggests that ABCC5,CHAT and PLEKHA7 might be associated with refractive errors by contributing to the regulation of ocular biometry,in terms of uncorrected results and their biological functions.
