Objective To investigate the value of temporary balloon occlusion of the abdominal aorta in the treatment of complete placenta previa with placenta accreta. Methods From January 2015 to February 2016, 24 cases of complete placenta previa with placenta accreta were treated with temporary balloon occlusion of the abdominal aorta (the study group) before cesarean, and 24 cases of complete placenta previa with placenta accreta did not receive balloon occlusion (the control group). The operation time, intraoperative blood loss, intraoperative blood transfusion volume, the perioperative hemoglobin level, the hysterectomy rate and the related complications were compared retrospectively.Also, the hospitalization time, the blood coagulation parameters after operation, including activated partial thromboplastin time (APTT), fibrinogen (FIB), D-Dimer and reperfusion injury parameters including creatine phosphokinase (CK), creatine phosphokinase isoenzyme (CK-MB), lactate dehydrogenase (LDH) and serum creatinine were compared between the 2 groups. Results The blood loss [750 ml (400-2 000 ml) vs 2 000 ml (1 500-2 375 ml);Z=-3.214, P=0.001] and blood transfusion volume [200 ml (0-800 ml) vs 800 ml (0-1 200 ml);173, P=0.030] in the study group were lower than in the control group. The hemoglobin difference between before and after operation in the study group was lower than the control group [(12.8±13.4) g/L vs (22.9±20.1) g/L;t=-2.041, P=0.047]. In the study group, there were still bleeding in 13 cases after releasing the balloon, 5 of them received uterine artery embolization, 5 cases received uterine artery ligation, and 3 cases received uterine packing. One case had venous thrombosis in the right lower limb. Two cases (8%,2/24) in the control group had hysterectomy, while none in the study group, there was no statistical significance (P=0.489). Conclusions Temporary balloon occlusion of the abdominal aorta can effectively reduce blood loss and blood transfusion in the treatment of complete placenta previa with placenta accreta, but there is still the risk of continuing bleeding after releasing the balloon. Other methods of hemostasis might be needed.

OBJECTIVETo investigate the effect of icariin (ICA) on learning and memory abilities and cholinergic system in senescence-accelerated mice SAMP10.
METHODThe 8-month-old senescence-accelerated mice were randomly divided into the model SAMP10 group and the positive Donepezil group (1 mg x kg(-1)) and ICA groups (50, 100, 200 mg x kg(-1)), with 12 mice in each group. Another 12 8-month-old mice SAMR1 were selected as the normal control group. After 30 days of oral administration, Morris water maze, SMG-2 water maze and experimental platform were used to test the effects of ICA on learning and memory abilities of SAMP10 groups. By colorimetric determination of AChE activity in the cortex, enzyme-linked immunosorbent assay detection of ACh, ChAT, MCBC of the cerebral cortex, the effect of ICA on the cholinergic system of SAMP10 was observed.
RESULTICA could improve the abilities of space exploration and positioning navigation of SAMP10, shorten the latency in SMG-2 water maze, enhance their jumping ability in response to the passive test, and increase levels of ACh, ChAT, MCBC in the cerebral cortex of SAMP10. But its active effect on AChE in SAMP10 cortex was not obvious.
CONCLUSIONDifferent doses of icariin can improve learning and memory abilities of SAMP10 to varying degrees, which may be related to its effect on the cholinergic system.

Objective To evaluate the effect of contrast medium on the renal function in patients with cerebrovascular disease accompanied by diabetes mellitus after receiving neuro - interventional therapy. Methods The clinical data of a total of 108 patients with cerebrovascular disease complicated by diabetes mellitus type 2, who were treated with neuro - interventional therapy during the period from March 2013 to March 2016, were retrospectively analyzed. The contrast dose used in interventional procedures was less than 250ml in each patient. The preoperative and 24 h -postoperative serum creatinine (sCr), serum cystatin C (Cys C) levels were determined, and based on the modification of dietary renal disease (MDRD) equation and Larsson equation the estimated glomerular filtration rates (eGFR) were separately calculated. Results Compared with preoperative values, the 24 h - postoperative mean sCr and Cys C levels were increased significantly (P=0. 001, P=0. 015 respectively), while the average eGFR rates were remarkably decreased (P< 0. 000 1 by using MDRD equation, and P=0. 021 by using Larsson equation). No kidney damage that needed to be treated occurred in all patients. Conclusion The contrast dose used in neuro - interventional procedures can cause decline of renal function in patients with type 2 diabetes mellitus. The combined determination of sCr and Cys C levels is helpful for the detection of contrast - induced changes in renal function as early as possible. The use of conventional dose of contrast agent in neuro - interventional procedures is safe for patients with type 2 diabetes mellitus. (J Intervent Radiol, 2018, 27:277-280)

Objectives:This study aimed to assess the efficacy and safety of bendamustine in combination with rituximab (BR regimen) for the treatment of newly diagnosed indolent B-cell non-Hodgkin's lymphoma (B-iNHL) and elderly mantle cell lymphoma (eMCL) .Methods:From December 1, 2020 to September 10, 2022, a multi-center prospective study was conducted across ten Grade A tertiary hospitals in Shandong Province, China. The BR regimen was administered to evaluate its efficacy and safety in newly diagnosed B-iNHL and eMCL patients, and all completed at least four cycles of induction therapy.Results:The 72 enrolled patients with B-iNHL or MCL were aged 24-74 years, with a median age of 55 years. Eastern Cooperative Oncology Group (ECOG) performance status scores of 0-1 were observed in 76.4% of patients, while 23.6% had scores of 2. Disease distribution included follicular lymphoma (FL) (51.4% ), marginal zone lymphoma (MZL) (33.3% ), eMCL (11.1% ), and the unknown subtype (4.2% ). According to the Ann Arbor staging system, 16.7% and 65.3% of patients were diagnosed with stage Ⅲ and stage Ⅳ lymphomas, respectively. Following four cycles of BR induction therapy, the overall response rate was 98.6%, with a complete response (CR) rate of 83.3% and a partial response (PR) rate of 15.3%. Only one eMCL patient experienced disease progression during treatment, and only one FL patient experienced a relapse. Even when evaluated using CT alone, the CR rate was 63.9%, considering the differences between PET/CT and CT assessments. The median follow-up duration was 11 months (range: 4-22), with a PFS rate of 96.8% and an OS rate of 100.0%. The main hematologic adverse reactions included grade 3-4 leukopenia (27.8%, with febrile neutropenia observed in 8.3% of patients), grade 3-4 lymphopenia (23.6% ), grade 3-4 anemia (5.6% ), and grade 3-4 thrombocytopenia (4.2% ). The main non-hematologic adverse reactions such as fatigue, nausea/vomiting, rash, and infections occurred in less than 20.0% of patients.Conclusion:Within the scope of this clinical trial conducted in China, the BR regimen demonstrated efficacy and safety in treating newly diagnosed B-iNHL and eMCL patients.
