AIM: To investigate the expression changes and significance of serum microRNA-34a-5p(miR-34a-5p)and silent information regulator T1(SIRT1)in patients with endophthalmitis after cataract surgery.METHODS: Patients with endophthalmitis after cataract surgery from May 2020 to May 2024 were selected as infection group(20 cases), and patients without endophthalmitis were selected as control group(74 cases). Serum SIRT1 levels were detected by ELISA; the serum level of serum miR-34a-5p was detected by qRT-PCR; the correlation between miR-34a-5p and SIRT1 was analyzed by Pearson method; Logistic regression was used to analyze the influencing factors of endophthalmitis after cataract operation. Receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of serum miR-34a-5p and SIRT1 levels in postoperative endophthalmitis.RESULTS: Compared with the control group, the serum level of miR-34a-5p in the infected group was significantly increased(P<0.001), and the serum level of SIRT1 was significantly decreased(P<0.001). Correlation analysis showed that miR-34a-5p was negatively correlated with SIRT1(r=-0.421, P<0.001). Logistic multivariate regression analysis showed that miR-34a-5p was an independent risk factor affecting endophthalmitis infection after cataract surgery(OR=3.532, P<0.05), and SIRT1 was a protective factor affecting endophthalmitis infection after cataract surgery(OR=0.875, P<0.05). The ROC curve showed that the area under curve(AUC)of serum miR-34a-5p combined with SIRT1 in the diagnosis of postoperative endophthalmitis was 0.933(95%CI: 0.861-0.975).CONCLUSION:Serum levels of miR-34a-5p are highly expressed and SIRT1 is lowly expressed in postoperative endophthalmitis, they are closely related to the occurrence and development of endophthalmitis after cataract surgery.

AIM: To explore the value of changes in the serum expression levels of triggering receptor expressed on myeloid cells-1(TREM-1)and matrix metalloproteinase-9(MMP-9)in early clinical diagnosis of postoperative endophthalmitis in patients with cataract surgery.METHODS: A total of 21 patients who underwent cataract surgery with infectious endophthalmitis in our hospital from May 2021 to May 2023 were selected as the study subjects(endophthalmitis group), and another 100 patients who underwent cataract surgery without endophthalmitis were selected as the non-endophthalmitis group. The serum levels of TREM-1, MMP-9, and the expression levels of inflammatory factors such as interleukin-1β(IL-1β), IL-17, and tumor necrosis factors-α(TNF-α)were detected and compared between the endophthalmitis group and the non-endophthalmitis group. The correlation between TREM-1 and MMP-9 was analyzed by Pearson method. Logistic regression was applied to analyze the factors that affected the occurrence of endophthalmitis in cataract patients after surgery. Receiver operating characteristic(ROC)curve was applied to analyze the early clinical diagnostic efficacy of TREM-1 and MMP-9 levels for postoperative endophthalmitis in cataract patients.RESULTS: Compared with the non-endophthalmitis group after cataract surgery, the expression levels of serum TREM-1, MMP-9, and inflammatory factors IL-1β, IL-17, and TNF-α in the endophthalmitis group were obviously increased(all P<0.05), and the TREM-1 was positively correlated with MMP-9(r=0.389, P<0.001). Logistic regression results showed that elevated levels of serum TREM-1 and MMP-9 expression, and vitreous overflow were independent risk factors for postoperative endophthalmitis in cataract patients(all P<0.05). ROC curve showed that the area under the curve(AUC)of TREM-1, MMP-9, and their combination in diagnosing postoperative endophthalmitis in cataract patients was 0.845, 0.844, and 0.935, respectively, and the clinical efficacy of the combination of the two in early diagnosis of postoperative endophthalmitis in cataract patients was better than that of serum TREM-1 and MMP-9 alone(all P<0.05).CONCLUSION: The expression levels of serum TREM-1 and MMP-9 in patients with endophthalmitis after cataract surgery are abnormally elevated, and the combination of the two has high clinical application value in early diagnosis of endophthalmitis after cataract surgery.

AIM: To investigate the predictive value of serum histone deacetylase 1(HDAC1)and endothelial nitric oxide synthase(eNOS)for infectious endophthalmitis after cataract surgery.METHODS: A total of 362 cataract patients(362 eyes)admitted to our hospital from January 2020 to January 2023 were selected as the research objects. According to the occurrence of postoperative infectious endophthalmitis, they were divided into infection group(15 cases, 15 eyes)and non-infection group(347 cases, 347 eyes). Enzyme linked immunosorbent assay(ELISA)was applied to detect the levels of serum HDAC1 and eNOS in all subjects, and the levels of serum HDAC1 and eNOS in both groups were compared; the influencing factors of infectious endophthalmitis were analyzed by multivariate Logistic regression; the receiver operative curve(ROC)was applied to analyze the predictive value of serum HDAC1 and eNOS levels for postoperative infectious endophthalmitis in cataract patients.RESULTS: The levels of serum HDAC1 and eNOS in the infected group were obviously higher than those in the uninfected group(all P<0.01). Surgical time, vitreous overflow, HDAC1, and eNOS were all risk factors for postoperative infectious endophthalmitis(all P<0.05). ROC results showed that the AUC of HDAC1 and eNOS in predicting postoperative infectious endophthalmitis in cataract patients was 0.878 and 0.877, respectively, with sensitivity of 88.7% and 87.7%, specificity of 70.4% and 7.8%, respectively, while the AUC of the two combination in predicting postoperative infectious endophthalmitis in cataract patients was 0.978, with a sensitivity of 86.7% and a specificity of 85.3%.CONCLUSION:The serum levels of HDAC1 and eNOS in patients with infectious endophthalmitis after cataract surgery are obviously increased, and the combined detection of serum HDAC1 and eNOS can improve the predictive efficacy of infectious endophthalmitis in cataract patients after surgery. Both can provide reference for clinical diagnosis and treatment.

Serious diseases and other negative events bring serious physical and mental damage to individuals, but there are still some individuals can construct positive meaning of life from adversity, which is closely related to the role of benefit finding. According to the theory of stress system, if negative events such as disease are taken as stressors, benefit finding can be regarded as a good manifestation of individual psychological stress response. At present, most of the studies on benefit finding are cross-sectional studies, ignoring the characteristics of its dynamic development and the predictive role of individual advantages and disadvantages on benefit finding. This paper reviews the predictive factors in the longitudinal study of benefit finding from protective factors and risk factors, in order to reduce the adverse effects of risk factors on the basis of exploring individual protective factors and provide a starting point for the research design of positive psychological cognitive intervention.

Co-delivery of chemotherapeutics and immunostimulant or chemoimmunotherapy is an emerging strategy in cancer therapy. The precise control of the targeting and release of agents is critical in this methodology. This article proposes the asynchronous release of the chemotherapeutic agents and immunostimulants to realize the synergistic effect between chemotherapy and immunotherapy. To obtain a proof-of-concept, a co-delivery system was prepared

Objective    To define the patient characteristics and perioperative management, and to define the mortality and its risk factors after arterial switch operation (ASO). Methods    We conducted a bidirectional cohort study with 571 consecutive patients undergoing ASO from 1997 to 2016 in our hospital. We enrolled patients who underwent ASO before 2012 retrospectively and after 2012 prospectively and followed up all the patients prospectively. Demographic characteristics, clinical information and mortality of these patients were summarized. Joinpoint regression analysis was used to identify the time trend of the overall mortality. Kaplan-Meier survival analysis was used to evaluate the mid- and long-term survival rate after ASO. Cox proportional hazards regression models were used to explore the potential factors associated with mortality. The cumulative incidence of complications after ASO was predicted using competing risk models. Results    Several aspects of patients’ characteristics and perioperative management in our center differed from those in the developed countries. The overall mortality and in-hospital mortality after ASO was 16.3% and 15.1%, respectively. The overall cumulative survival rate at 5, 10 and 15 years after ASO was 83.3%, 82.8% and 82.8%, respectively. A significant decrease of overall mortality from 1997 to 2016 was observed. Independent risk factors of mortality included earlier ASO (1997-2006), single or intramural coronary anatomy and longer cardiopulmonary bypass time. Ten years after ASO, re-intervention, arrhythmia, pulmonary and anastomotic stenosis were the most common complications with a cumulative incidence over 10%. Conclusion    Significant improvements in the results of the ASO were observed and the postoperative mortality rate is close to reports from developed countries. Nonetheless, we have identified the need for further improvement in the early and late postoperative periods after ASO. Pulmonary stenosis, anastomotic stenosis and arrhythmia should be paid attention to during the long-term follow-up after ASO.

Objective:To explore the influencing factors of the failure of labor induction by oxytocin and delivery outcome, and provide a basis for standardizing pregnancy management and process management of labor induction by oxytocin.Methods:Using a self-designed data collection form, the data of 1 705 pregnant women who underwent labor induction by oxytocin in the Department of Obstetrics of China-Japan Friendship Hospital from 2014 to 2018 were retrospectively collected, and the influencing factors of the failure of labor induction by oxytocin and the outcome of delivery were analyzed.Results:A total of 1 705 primary mothers were included in the study. Multiple factor analysis show that, amniotic fluid pollution, macrosomia, and the duration of labor induction by oxytocin were independent influencing factors for the failure of labor induction by oxytocin. The duration of labor induction by oxytocin was related to the method of delivery, weight of the newborn, and amount of postpartum hemorrhage, and the difference was statistically significant ( P<0.01) . The outcome of delivery labor induction by oxytocin was the cause of cesarean delivery, and "intrauterine fetal distress" and "cephalopelvic disproportion" accounted for the highest proportion. Conclusions:The main influencing factors for the failure of labor induction by oxytocin are amniotic fluid pollution, macrosomia, etc., and the influencing factors will gradually increase with the process of labor induction, thereby reducing the natural delivery rate. Therefore, it is necessary to strengthen pregnancy management, control pregnancy weight and fetal weight, and reduce pregnancy complications. It is also necessary to strengthen clinical management of labor induction by oxytocin, provide sound education and guidance for labor induction by oxytocin, and increase the vaginal delivery rate after labor induction by oxytocin.
