Objective:To compare and observe the visual acuity and ocular anatomical outcome of different subtypes in open-globe injury (OGI) Ⅲ.Methods:A retrospective study. A total of 187 eyes of 187 patients with OGI involving zone Ⅲ who were admitted to the Department of Ophthalmology of The First Affiliated Hospital of Army Medical University from January 2020 to December 2023 were included in the study. According to the 2022 International Globe and Adnexal Trauma Epidemiology Study groups consensus, zone Ⅲ was further divided into Ⅲa zone (5-8 mm posterior to the limbus) and Ⅲb zone (>8 mm posterior to the limbus), with 58 eyes (31%, 58/187) in group Ⅲa and 129 eyes (69%, 129/187) in group Ⅲb. Best corrected visual acuity (BCVA) was examined using the international standard decimal visual acuity chart, converted into the logarithm of the minimum angle of resolution (logMAR) visual acuity when recorded. The injured zone, initial visual acuity, final visual acuity, retinal detachment (RD), uveal prolapse, and proliferative vitreoretinopathy (PVR) were collected. The follow-up time after surgery ≥ 6 months. The final visual acuity and anatomical prognosis of the two groups were observed. Silicone oil dependence, phthisis, and enucleation were defined as poor anatomical outcomes. Multiple linear regression analysis was performed to analyze the impact of zone Ⅲb of OGI on the final visual acuity.Results:At the 6-month follow-up, the logMAR BCVA of group Ⅲa and group Ⅲb was 1.49±1.0 and 2.51±0.85; there was a statistically significant difference in the logMAR BCVA between the two groups ( t=-2.736, P<0.05). Compared with group Ⅲa, the proportion with light perception in group Ⅲb was higher, and the proportions with visual acuity of hand movement, counting fingers, and >0.01 were lower, and the differences were all statistically significant ( P<0.05). Compared with group Ⅲa, RD and PVR were more likely to occur in group Ⅲb, and the differences were all statistically significant ( χ2= 16.696, 8.697; P<0.05). Among the affected eyes in group Ⅲa and group Ⅲb, there were 14 eyes (24.1%, 14/58) and 95 eyes (73.6%, 95/129) with poor final anatomical outcomes respectively; the incidence of poor final anatomical outcomes in group Ⅲb was higher, and the difference was statistically significant ( χ2= 40.332, P<0.01). The results of multiple linear regression analysis showed that initial visual acuity, RD, and uveal prolapse were independent risk factors affecting the final visual acuity (odds ratio=2.407, 4.162, 3.413; P<0.05). Conclusions:Patients with OGI in zone Ⅲb have a worse visual prognosis and a higher incidence of poor anatomical outcomes. The subclassification of zone Ⅲ is helpful for better predicting the prognosis of OGI clinically.
2.A brief review and comparison of study and prevention achievements on key endemic diseases between Japan and China
Chinese Journal of Endemiology 2025;44(9):762-766
As a highly prevalent disease in a specific geographical area, endemic diseases pose a serious challenge to public health. This article systematically reviews the epidemiology, etiology, and preventive and control measures of major endemic diseases in Japan, such as schistosomiasis, Shinshu cardiomyopathy, iodine deficiency disorders, and endemic fluorosis, and compares and analyzes the similarities and differences in endemic diseases between China and Japan. Research has found that Japan has successfully controlled the prevalence of schistosomiasis, Shinshu cardiomyopathy, iodine deficiency disorders, and endemic fluorosis through comprehensive intervention measures such as snail control projects, selenium supplementation, iodized salt promotion, and water improvement to reduce fluoride levels. China has also accomplished remarkable feats in the continuous elimination of endemic diseases. The two countries have both similarities and differences in the distribution of endemic disease, epidemic factors, and prevention and control experience. Japan's experience in refined public health management is worth learning from, and China's large-scale prevention and control network construction also provides reference for Japan.

Auto-inhibited Ca2+-ATPase (ACA) is one of the Ca2+-ATPase subfamilies that plays an important role in maintaining Ca2+ concentration balance in plant cells. To explore the function and gene expression pattern of the RcACA gene family in castor, bioinformatics analysis was used to identify the members of the RcACA gene family in castor. The basic physical and chemical properties, subcellular location, protein secondary and tertiary structure, conserved domain, conserved motif, gene structure, chromosome location and collinear relationship, as well as the evolutionary characteristics and promoter cis-acting elements were predicted and analyzed. The expression pattern of the RcACA gene under abiotic stress was analyzed by expression (fragments per kilobase of exon model per million mapped fragments, FPKM) in castor transcriptome data. The results showed that 8 RcACA gene family members were identified in castor, acidic proteins located in the plasma membrane. In the secondary structure of all proteins, the α-helix and random coil is more; the RcACA genes were clustered into three categories, and the design of the genes in the same category was similar to the conserved motif. Both of them had four typical domains, RcACA3-RcACA8 had a Ca2+-ATPase N-terminal autoinhibitory domain. The RcACA gene is mostly located on the long arm of the chromosome and has 2 pairs of collinear relationships. There are more light response elements but fewer hormone-induced elements located upstream of the RcACA coding region. Interspecific clustering showed that the evolution of ACA genes among species was conservative. Tissue expression pattern analysis showed that RcACA genes showed apparent tissue expression specificity, and most of the genes showed the highest expression level in male flowers. Expression analysis under abiotic stress showed that RcACA2-RcACA8 were up-regulated under high salt and drought stress, and RcACA1 was up-regulated at 0-24 h under low-temperature stress, indicating that RcACA genes positively responded to abiotic stresses. The above results provide a theoretical basis for exploring the role of the RcACA gene in castor growth, development and stress response.

Objective:To construct an entrustable professional activities (EPAs) assessment framework for undergraduate medical students suited to the national conditions in China.Methods:The Delphi method was used to construct an EPAs assessment framework for medical undergraduates. Twenty-one clinical experts across China were invited to participate in two rounds of Delphi consultation.Results:All the 21 experts completed the two rounds of Delphi consultation. The effective questionnaire response rates of the two rounds of consultation were 100.0% (21/21). For the first-round expert consultation, the W values of importance and feasibility scores of EPAs were 0.182 and 0.173 (both P<0.05), respectively. For the second-round expert consultation, the W values of importance and feasibility scores of EPAs were 0.167 and 0.152 (both P<0.05), respectively. According to the second-round Delphi consultation, the importance and feasibility scores of all 14 EPAs indicators were >3.5 points, with the coefficients of variation <0.25 points. We preliminarily established 12 EPAs indicators and 42 key assessment points and determined the expected entrustment levels of each EPA at different stages for medical undergraduates. Conclusion:This study preliminarily constructed an EPAs assessment framework for medical undergraduates, which provides a new evaluation method for the cultivation of medical undergraduates in China.

The epidemiological characteristics and trends in the world and major countries were analyzed, and the main factors affecting the prevention and control of the epidemic were studied. SPSS19.0 software was used to collate data and statistical analysis.Results:The worldwide cumulative confirmed cases of COVID-19 reached 1 million on April 2, 2020, 10 million cases on June 28, 2020, 100 million cases on January 25, 2021, 200 million cases on August 3, 2021, 300 million cases on January 6, 2022, 400 million cases on February 8, 2022, 489 million cases on March 31, 2022. From January 2020 to March 31, 2022, the interval between each additional 100 million cases was gradually shortened (about 360 days from the beginning of the epidemic to the increase to 100 million, the average time to increase from 100 million to 200 million, from 200 million to 300 million was 170 days, and the number of confirmed cases increased from 300 million to 400 million was only 33 days), the epidemic had accelerated. The worldwide cumulative number of death case was 100 000 on April 9, 2020, 1 million on September 19, 2020, 5 million on October 31, 2021, and 6.14 million on March 31, 2022. From January to October 2021, the average time interval for an increase of 1 million deaths was 97 days. After October, the growth rate decreased, averaging 121 days. At the end of 2021, affected by the Omicron mutation, the number of infected people worldwide increased sharply. By March 31, 2022, the cumulative number of confirmed cases in all continents was Europe (181 million), Asia (141 million), North America (94.67 million), South America (56.09 million), Africa (11.55 million) and Oceania (5.58 million) from high to low. The cumulative deaths from high to low was Europe (1.77 million), North America (1.42 million), Asia (1.41 million), South America (1.28 million), Africa (0.25 million) and Oceania (8 900). The top 5 countries with cumulative confirmed cases of COVID-19 were the United States (80.14 million), India (43.03 million), Brazil (29.98 million), France (25.82 million) and the United Kingdom (21.28 million). The top five countries with accumulated deaths were the United States (980 000), Brazil (660 000), India (520 000), the United Kingdom (160 000) and France (140 000).Conclusions:COVID-19 is a global public health emergency. The epidemic has spread worldwide with strong infectivity, rapid transmission and great harm. It is suggested to focus on the prevention and control of key links, strengthen the early warning mechanism, continue to take scientific public health prevention and control measures such as vaccination, reduce severe case and death and deal with an ongoing challenge.

Objective:To study the effect of iodine excess on antioxidant capacity and blood lipid in adult.Methods:A survey was conducted in areas with different iodine nutrition levels in Shandong and Shanxi provinces to collect fasting morning urine and venous blood samples of adults. Urinary iodine, serum levels of superoxide dismutase(SOD), malondialdehyde (MDA), total cholesterol (TCHO), triglyceride (TG), apolipoprotein A1 (apoA1) and apolipoprotein B (apoB), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were determined. According to the median urinary iodine of the population in the investigated village, they were divided into appropriate iodine group (100-299 μg/L) and iodine excess group (≥300 μg/L) . Multiple linear regression was used to analyze the effects of iodine nutrition and other factors on oxidative stress indexes and blood lipids. Partial correlation analysis was used to analyze the relationship between iodine nutrition and oxidative stress indexes and blood lipids.Results:A total of 1 049 subjects were included, including 471 in the appropriate iodine group and 578 in the iodine excess group. The median (quartile) urinary iodine of the appropriate iodine group and the iodine excess group was 228.70 (157.02, 341.49) and 558.73 (298.06, 985.06) μg/L, respectively. The serum SOD level of the appropriate iodine group and the iodine excess group was 12.60 (10.83, 14.10) and 11.29 (9.18, 13.10) U/ml, respectively, and the difference between the groups was statistically significant ( U = 92 697.50, P < 0.001). There were statistically significant differences in serum TG, HDL-C and apoB levels between the appropriate iodine group and the iodine excess group ( U = 108 879.50, 96 613.50, 99 050.50, P < 0.05). The results of multiple linear regression showed that after excluding age, gender and body mass index (BMI), there was a negative correlation between iodine nutrition and serum SOD and HDL-C levels [standard regression coefficient ( β) = - 0.196, - 0.294, P < 0.001]. Partial correlation analysis showed that there was a negative correlation between iodine nutrition and serum SOD and HDL-C levels [correlation coefficient ( r) = - 0.16, - 0.09, P < 0.05]. Conclusion:Excessive iodine intake affects oxidative stress and lipid metabolism in human body.
