Objective To explore the application of temporary balloon occlusion in multidisciplinary management of cesarean sec-tion for patients with pernicious placenta previa/accreta.Methods 42 patients with a diagnosis of placenta previa /accrete accepted the temporary aortic balloon occlusion in cesarean section in DSA hybrid operation room were retrospectively studied.Before cesare-an section,intravascular balloon catheter was placed in abdominal aortic.After delivery,the midpoint of filling state balloon was placed at the midpoint of the two renal arteries openings before placental dissection.The amount of blood loss and blood transfusion, operation time,the infants'radiation doses and postoperative complications were determined.Results All patients were successfully fulfilled cesarean section and conserved uteri.The amount of blood loss,blood transfusion,operation time,occlusion time and the infants’radiation doses were (586±355)mL,(422±283)mL,(75.5±1 1.9)min,(22.4±7.2)min and (4.2±2.9)mGy,respec-tively.During follow-up,complications were not found during operation and after operation.Conclusion In women with pernicious placenta previa/accreta,temporary aortic balloon occlusion can effectively control postpartum hemorrhage and reduce the risk of un-desirable hysterectomy.

Objective To investigate the microRNA ( miRNA ) expression level of peripheral blood mononuclear cell ( PBMC) in autoimmune diabetes mellitus ( ADM) which includes type 1 diabetes mellitus ( T1DM) and latent autoimmune diabetes in adults ( LADA ) , T2DM patients, and matched healthy individuals. Methods Patients of T1DM, LADA, and T2DM were recruited in the Second Xiangya Hospital of Central South University from January 2015 to December 2016. The subjects were divided into two groups. The first group was used for high-throughput screening of differentially expressed microRNAs. The second group was used to validate the expression of miR-142-5p and miR-143-3p by real-time quantitative polymerase chain reaction (RT-qPCR). Results (1)The different miRNA expression patterns of PBMC were found among T1DM patients, LADA patients, T2DM patients, and health individuals. ( 2) Compared with T2DM patients and healthy controls, LADA and T1DM patients had down-regulated PBMC miR-142-5p expression, and up-regulated miR-143-3p expression. (3)RT-qPCR validation showed that the expression of miR-142-5p in LADA patients was significantly lower than that in T2DM patients (0.30±0.24 vs 1.33 ± 1.29, P<0.05) . The expression of miR-143-3p in T1DM and LADA was higher than that in T2DM and health individuals. However, no significant differences were found. Conclusion The miRNA expression patterns are different in the PBMC of T1DM patients, LADA patients, T2DM patients, and healthy individuals; the abnormal expressions of miR-142-5p and miR-143-3p may participate in the development of ADM by affecting apoptosis and immune cell differentiation.

Objective To explore the changes in serum energy metabolites in patients with peripheral T-cell lymphoma,and investigate serum biomarkers for monitoring peripheral T-cell lymphoma from the perspective of energy metabolism.Methods Multiple/selected reaction monitoring(MRM/SRM)was used to detect the energy-related metabolites in the sera of 16 patients with newly diagnosed peripheral T-cell lymphoma admitted in the Hematology Medical Center of the Second Affiliated Hospital of Army Medical University from November 2020 to December 2021,as well as 10 recruited healthy volunteers.The corresponding clinical data including medical history,laboratory results and image data were collected and retrospectively analyzed.Results Significant differences were seen in the contents and expression profiles of serum energy metabolism-related products between the patients and the healthy volunteers.The patients had significantly reduced serum contents of cyclic AMP,succinate,citrate and cis-aconitate(P<0.05),and elevated D-glucose 6-phosphate content(P<0.05).The serum contents of citrate and succinate were negatively correlated with the risk stratification(low-,moderate-and high-risk)and clinical stage of the disease(P<0.05).Meanwhile,there was a negative correlation between the contents of L-malic acid and citrate and the mid-term efficacy evaluation results,such as complete/partial response(CR/PR)or stable disease(SD)(P<0.05).For patients with extranodal NK/T cell lymphoma(n=10),there were also significant reductions in the contents of cyclic AMP,succinate,citrate,isocitrate and cis-aconitate in the sera of patients compared with healthy volunteers(P<0.05),and the contents of citrate and succinate were negatively correlated with the clinical stage(P<0.05)and were rather correlated with mid-term efficacy evaluation results(CR/PR or SD)(P<0.05).For patients with angioimmunoblastic T-cell lymphoma(n=6),the serum contents of cyclic AMP,citrate and succinate were significantly lower,while the content of D-glucose 6-phosphate was higher when compared with the healthy volunteers(P<0.05),and the content of succinate was negatively correlated with both clinical stage and risk grade of the patients(P<0.05).Conclusion There are 5 serum differential metabolites identified between patients with peripheral T-cell lymphoma and healthy controls,and succinate and citrate are expected to be serum biomarkers of peripheral T-cell lymphoma.
