AIM: To explore the risk factors of retinal detachment after stage II vitrectomy in patients with open ocular trauma.METHODS: Retrospective analysis. Totally 278 patients(278 eyes)with open ocular trauma who received stage II vitrectomy in the hospital were included from April 2020 to July 2023. According to the postoperative retinal detachment status, they were divided into detachment group(48 eyes)and non-detachment group(230 eyes). The basic clinical conditions of the two groups of patients were compared, and the factors affecting retinal detachment were analyzed.RESULTS: Univariate analysis revealed that there were statistical differences in wound length, injured area, surgical time after injury, and history of retinal detachment/lesion between the two groups(all P<0.05). Logistics multivariate regression analysis showed that wound length greater than 10 mm, surgical time after injury more than 1 wk, and history of retinal detachment/lesion were risk factors for retinal detachment in patients with open ocular trauma after stage II vitrectomy(all P<0.05).CONCLUSION: The occurrence of retinal detachment in patients with open ocular trauma after stage II vitrectomy is mainly related to the severity of trauma, surgical time after injury and history of ocular retinopathy. It is necessary to perform surgical treatment for patients as soon as possible.

Objective To discuss the effect of multidisciplinary family empowerment mode in home care for patients after receiving percutaneous endoscopic gastrostomy(PEG).Methods A total of 86 patients,who received initial PEG at the Jilin Provincial Cancer Hospital of China from January 2021 to July 2023,were selected for this study.The patients were randomly divided into observation group.The patients of the control group received routine nursing guidance for gastrostomy,while the patients of the observation group received multidisciplinary family empowerment nursing mode.The self-care ability[using self-care ability scale of the elderly(SASE)score],health behavior ability[using self-rating scale of health behavior ability(SRAHP)score],incidence of complications,and healing time of complications were compared between the two groups.Results In the observation group the SASE[(129.48±5.48)points vs.(73.05±12.04)points]and the SRAHP[(80.14±1.00)points vs.(70.25±7.92)points]were significantly higher than those in the control group(all P＜0.05),the incidence of complications was lower than that in the control group,and the healing time of complications was shorter than that in the control group.Conclusion The implementation of multidisciplinary family empowerment nursing mode can improve the self-care ability and health behavior ability of patients after receiving PEG,reduce postoperative complications,as well as shorten the healing time of complications,therefore,this nursing mode is suitable for home patients after receiving PEG.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Organoids are three-dimensional (3D) biological structures constructed in vitro by stem cells, which partially mimic the function of real organs. Brain organoids are an extremely important branch of organoid research. This technology can differentiate pluripotent stem cells into the required cell types in a 3D culture environment, and self-assemble into structural bodies, but it is currently unable to fully replicate the structural and physiological features of the real human brain. The maturity of brain organoids may form consciousness, which poses ethical issues such as determining moral status and informed consent in brain organoids research. This paper elaborated on the research progress and future development direction of brain organoids, and proposed multidimensional governance strategies for ethical issues faced in brain organoids research from the perspectives of ethical principles, ensuring public informed consent, and legal supervision. By exploring the above issues, reference will be provided for formulating ethical principles to guide the research and application of brain organoids in the future.

【Objective】 To investigate the basic situation of blood donation given by university students in Tianjin and provide data to support the sustainable development of college blood donation. 【Methods】 The group blood donation in Tianjin universities from 2012 to 2021 was enrolled as the study group and other whole blood donors in the same period as the control. The statistical analysis of the two groups was conducted. 【Results】 From 2012 to 2021, the number of college blood donations in Tianjin increased from 8.93% to 21.32%, with the average annual growth rate of 12.80%, and the units of blood donated increased from 5.44% to 18.82%, with the average annual growth rate of 17.06%. The repeat donation rate in the study group was significantly lower than that of the control(20.74% vs 25.47%, P<0.05). In 2012, the specification of blood donated by college students were mainly 200 mL(87.38%), then in 2021, gradually transitioned to 400 mL(38.77%), followed by 200 mL(35.19%) and 300 mL(26.03%). The rates of 200/300 mL donation and insufficient blood donation in the study group were significantly higher than those in the control, to the contrary, the rate of 400 mL donation was lower in comparison to the control, with statistically significant differences. The deferral rates of initial screening and ALT among college donors differed significantly over the decade: HBsAg showed a significant downward trend, while Hb increased significantly(P<0.05); the deferral items in the study group was significantly lower than the control(P<0.05), except Hb. During the retest period, the deferral rates of ALT and HBV were decreasing, which was the lowest in 2018 then bounced back slightly; the deferral rate of HIV showed a increasing tendency(P<0.05). The deferral rates of all retest items in the study group were lower than those in the control(P<0.05). In the study group, no significant differences were noticed in the deferral rates of retest items by genders, except for ALT and HCV, as males were higher than females. 【Conclusion】 College student groups are an important force in blood donation. A long-term mechanism should be established to safeguard this special group and to provide targeted health education and personalised services to promote the sustainable and healthy development of blood donation in universities.

【Objective】 To investigate the unqualified rate of anti-HIV detection of blood screening laboratories in Beijing-Tianjin-Hebei region, and explore the differences in anti-HIV detection ability and influencing factors in each laboratory. 【Methods】 Through filling questionnaires via e-mail, the anti-HIV ELISA unqualified rate and confirmed (WB) positive results (data) from January to December 2018 from 15 blood screening laboratories in Beijing-Tianjin-Hebei region were collected. Our laboratory was responsible for data collection and confirmation, and statistics software SPSS22.0 was used for analysis. 【Results】 1) There was a statistically significant difference among the unqualified rate of anti-HIV ELISA(6.77‱~35.71‱) and confirmed positive rate(0.60‱~3.56‱) in 15 blood screening laboratories in Beijing-Tianjin-Hebei region (P<0.05); 2) There were significant differencse among the ELISA unqualified rate and the confirmed positive rate of 8 reagents for anti-HIV detection(P<0.01), and the sensitivity of the 4th generation detection reagent and the imported reagent was higher than that of the 3rd generation reagent and the domestic reagent. The anti-HIV ELISA unqualified rate of R5 was the highest (19.08‱). 3)There were significant differences in the anti-HIV ELISA unqualified rate of R1, R2, R3, R5 and R7 reagents among different blood station laboratories(P<0.05), and there were no significant differences in the anti-HIV ELISA unqualified rate of R4, R6 and R8 reagents among different blood station laboratories(P>0.05). 4)The unqualified rate of anti-HIV ELISA of laboratories using different regents showed significant differences(P<0.05), except H, J, M. The unqualified rate of imported reagent was significantly higher than that of domestic reagents of laboratories using imported and domestic reagents combinations(P<0.05), except O. 62.5% (5/8) laboratories using domestic 3^rd and 4^th generation reagent combination showed significant differences in the unqualified rates among different reagents(P<0.05); 5) The positive rate of single-reagent(62.02%~95.45%)in 15 blood screening laboratories showed significant difference(P<0.001), and A was the lowest (62.02%). 【Conclusion】 The anti-HIV detection ability among 15 blood screening laboratories in Beijing-Tianjin-Hebei region is quite different. The application of different reagents is the main factor for the difference, and other factors such as personnel, instruments and test strategies also has a great impact on the detection of anti-HIV. It is still necessary to promote the process of homogenization of blood testing quality among blood screening laboratories in Beijing-Tianjin-Hebei region.

[摘 要] 目的：检测长链非编码RNA（long non-coding RNA，lncRNA）ARHGAP5-AS1在乳腺癌组织及细胞中的表达，分析其表达与患者临床病理参数及预后的相关性，并初步探讨其对乳腺癌细胞体外增殖、迁移和侵袭的影响。方法：通过对TCGA数据库中乳腺癌相关数据集的生物信息学分析，筛选出在乳腺癌中低表达且与患者不良预后相关的lncRNA ARHGAP5-AS1，采用qPCR方法在江南大学附属医院肿瘤科从2010年4月至2016年10月收集的乳腺癌组织中验证其表达。采用χ2检验分析ARHGAP5-AS1表达与乳腺癌患者临床病理参数之间的关系，Kaplan-Meier生存分析构建生存曲线，比较高、低表达组的总生存期和无复发生存期。CCK-8实验、划痕实验和Transwell实验分别检测ARHGAP5-AS1敲低对乳腺癌细胞MDA-MB-231和BT-549的增殖、迁移和侵袭的影响。结果：TCGA数据库分析结果显示，ARHGAP5-AS1在乳腺癌组织中的表达水平显著低于正常乳腺组织（P<0.01），其低表达与较大肿瘤直径（T3）、远处转移（M1）、ER和PR阴性以及较短的总生存期显著相关（均P<0.05）。乳腺癌组织中ARHGAP5-AS1表达水平显著低于癌旁组织（P<0.05），其低表达与较大的肿瘤直径和淋巴结转移相关（均P<0.05）。同样，ARHGAP5-AS1在6株人乳腺癌细胞系（MDA-MB-231、BT-549、MDA-MB-468、MCF-7、HCC1937、Hs578T）中的表达水平也显著低于正常乳腺上皮细胞系（MCF-10A）（均P<0.05）。细胞功能实验显示，ARHGAP5-AS1敲低促进MDA-MB-231和BT-549细胞的增殖、迁移和侵袭（均P<0.05）。结论：ARHGAP5-AS1异常低表达可能通过促进乳腺癌细胞的增殖、迁移和侵袭影响乳腺癌的发生发展。

Objective:To investigate the nurses' attitude towards open visitation policy in intensive care unit (ICU) and its potential influence factors, and further to provide evidence for carrying out this policy in ICU.Methods:A self-designed, anonymous online questionnaire of "attitude of ICU nurses to open visiting system in ICU" was performed in 31 provinces, autonomous regions and municipalities in China from October to December 2019, using convenient sampling method approach. Only nurses working in ICU (including specialized ICU, but excluding the critical ward in general ward) and willing to participate in the survey were included. The survey included 35 items, including the general information of each participant, the attitude towards the implementation of the open visitation system in ICU and its potential influencing factors. Ordinal Logistic regression analysis was used to identify the significant influencing factors.Results:A total of 1 558 questionnaires were sent out and 1 546 effective questionnaires were retrieved, with a response rate of 99.2%. Overall, 32.2% of them agreed with the policy, 41.3% of them disagree with the policy and 26.5% of them were uncertain. The Ordinal Logistic regression analysis showed that the independent influencing factors of ICU nurses' attitude towards open visitation policy including the possibility of increasing healthcare-associated infection [disagree: β = 1.327, 95% confidence interval (95% CI) was 0.242 to 2.413, P = 0.017; uncertain: β = 0.697, 95% CI was 0.244 to 1.151, P = 0.003], the improvement of nurses' job satisfaction (disagree: β = -1.406, 95% CI was -1.750 to -1.062, P = 0.000; uncertain: β = -0.748, 95% CI was -1.030 to -0.466, P = 0.000), the information support for medical staffs from family members (disagree: β = -0.644, 95% CI was -1.048 to -0.240, P = 0.002; uncertain: β = -0.422, 95% CI was -0.721 to -0.124, P = 0.006), the feasibility that the family members can assist the nurses in the basic nursing for patients (uncertain: β = -0.465, 95% CI was -0.729 to -0.202, P = 0.001), reducing the time that a nurse spent on caring for the patients (uncertain: β = 0.349, 95% CI was 0.052 to 0.646, P = 0.021), improving early rehabilitation (disagree: β = -0.593, 95% CI was -1.166 to -0.019, P = 0.043), and getting psychological support for patients from family members (disagree: β = 1.293, 95% CI was 0.426 to 2.159, P = 0.003), family members' satisfaction (disagree: β = -0.981, 95% CI was -1.431 to -0.531, P = 0.000). Conclusion:ICU nurses in China have realized that open visitation policy has positive effect on patients' early rehabilitation, willing to live and satisfaction; meanwhile, this policy may need more improvement in many ways such as healthcare-associated infection control, disinfection and isolation, allocation of human resources and time spent treating and caring for patients.

Objective: To understand the AIDS awareness and related factors as well as the demands for AIDS-related health education programs, among first-grade students from three senior high schools in Tianjin. Methods: A cross-sectional study using both stratified cluster and convenient sampling methods was conducted. Anonymous questionnaires including social demographic characteristics, AIDS-related knowledge and needs for AIDS health education were distributed to the first-grade students from two general middle schools and one vocational senior middle school in Tianjin. Results: A total of 1 082 students were responding to the questionnaires. Among them, the overall awareness rates of AIDS-related knowledge were 34.3%(371/1 082), 71.9%(778/1 082) of the students had received knowledge about AIDS and 59.4% (643/1 082) of the students had received knowledge about sexual health in the past, from the three schools. There appeared statistical differences among the two types of schools. 7.0% (76/1 082) of the students reported having had sexual behaviors. Results from the multivariate logistic regression analysis showed that, in vocational senior middle school, the awareness rate of AIDS knowledge was lower (compared with general middle school, OR=0.41, 95%CI: 0.29-0.59) and in the following items, including no need in receiving safe sex health knowledge (compared with needs of safe sex health knowledge, OR=0.62, 95%CI: 0.43-0.91), no interests in reading AIDS-related health education materials (compared with attention to AIDS health education materials, OR=0.41, 95%CI: 0.30-0.56), not aware of safe sex behavior (compared with aware of safe sex behavior, OR=0.55, 95%CI: 0.39-0.77), not aware of correct condom use, compared with aware of correct condom use (OR=0.33, 95%CI: 0.24-0.46). Conclusions The overall awareness rate of AIDS knowledge was low among the first-grade students in Tianjin. Some students reported of already having had insertive sex, sexual health knowledge has a significant impact on AIDS knowledge, suggesting that sexual health education and AIDS health education among high school students be strengthened in Tianjin.
