Background The generation of advanced glycosylation end products (AGEs) is one of the most important characteristics in diabetes mellitus (DM).Its role in diabetic eye disease is still unclear.Objective This study was to investigate the changes of AGE levels in human cataractous lens in diabetic patients and further explore the relationship of lens AGEs with early diabetic retinopathy (DR).Methods This study protocol was approved by Ethic Committee of He Eye Hospital.A cases controlled clinical study was carried out.Forty human nuclei were obtained from 40 cataract patients during the phacoemulcification in He Eye Hospital from August to December 2014,with the nuclear hardness of Ⅲ-Ⅳ grades (Emery grading).The eyes were divided into non-DM (NDM) group and DM group,and the DM group was further divided into non-DR (NDR) group,non-proliferative DR (NPDR) group and proliferative DR (PDR) group.Lens AGE level was quantitatively detected by ELISA.Results The content of pentosidine was (31.90±5.00),(35.83±4.22) and (38.59±5.11)pg/ml,and that of carboxymethyl lysine (CML) was (18.82±3.84),(19.65±2.12) and (23.77±4.73) μg/L,and that of imidazolone was (13.12±2.71),(14.48±2.01) and (15.37 ±2.74) pg/ml in the NDR group,NPDR group and PDR group,respectively,which was significantly higher than (27.69 ± 1.53) pg/ml,(11.36 ±1.47) μg/L and (10.21 ± 0.54) pg/ml in the NDM group (all at P<0.01).The contents of pentosidine and CML in the lens were significantly higher in the PDR group than those in the NDR group (all at P<0.05);while there was no significant differences in the pentosidine content in the lens among the NDR group,NPDR group and PDR group (all at P>0.05).The positive correlations were found between CML content and pentosidine content (r =0.623,P =0.000),between CML content and imidazolone content (r =0.717,P =0.000) as well as between pentosidine content and imidazolone content (r=0.669,P =0.000).Conclusions The levels of pentosidine,CML and imidazolone in cataractous lens are obviously elevated in the DM patients.The levels of pentosidine and CML in the lens are gradually raised as the aggravation of DR.AGEs might be a potential maker for the assessment of diabetes.

Objective To analyze the risk factors associated with multiple organ dysfunction syndrome (MODS) in children after cardiopulmonary bypass (CPB).Methods Between Jan 2001 and Dec 2010,1 899 patients undergoing open heart surgery were reviewed retrospectively according to the presence or absence of MODS.Univariate and multivariate logistic regression analysis were used to identify the risk factors.Results Thirty-five patients (1.84%) developed MODS,the mortality for MODS was 51.43% (18/35).Univariate risk factors included complex congenital heart disease,perioperative unexpected events,CPB time,aortic cross-clamping time,mechanical ventilation time,and postoperative spsis.Multivariate logistic regression analysis identified that complex congenital heart disease,perioperative unexpected events,CPB time > 180 min,postoperative spsis were risk factors.Conclusion The results suggest that the patients with MODS risk factors described above need more careful peri and post operative surveillance and preventive management.

Objective:To evaluate the prognostic value of sepsis-induced coagulopathy (SIC) in patients with sepsis.Methods:From January 2019 to December 2021, patients with sepsis admitted to the Intensive Care Unit of our hospital were retrospectively classified into the SIC group and non-SIC group according to SIC diagnostic criteria. The baseline clinical data, severity score, total length of hospital stay, length of ICU stay and 28-day survival were compared between the two groups. Kaplan-Meier was used to compare the 28-day survival of patients with sepsis between the two groups. Cox proportional hazard regression model was employed to analyze the risk factors of prognosis in patients with sepsis.Results:Totally 274 patients with sepsis were included in the analysis, including 139 patients in the SIC group and 135 patients in the non-SIC group. The two groups were compared in the perspectives of the Platelet count (PLT), prothrombin time (PT) , procalcitonin (PCT), D dimer, hematocrit, red blood cell distribution width, hemoglobin, acute kidney injury (AKI), the use of continuous renal replacement treatment (CRRT), the use of vasoactive drugs, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHEⅡ) score were compared between the two groups and the difference were statistically different (all P<0.05). Kaplan-Meier analysis showed that the 28-day mortality rate in the SIC group was significantly higher than that in the non-SIC group (32.4% vs. 14.1%, P<0.05). COX proportional hazard model showed that SIC score ( HR= 2.17, 95% CI: 1.15-3.91, P<0.05), APACHEⅡ score ( HR= 1.13, 95% CI: 1.09-1.17, P<0.05) and the use of vasoactive drugs ( HR=3.66, 95% CI: 1.53-8.75, P<0.05) were independent influencing factors for 28-day death in patients with sepsis. Conclusions:Patients with sepsis and SIC have more severe disease and increased mortality risk. SIC score exhibits good clinical value in predicting the prognosis of patients with sepsis.
