Objective: To explore the effects of combined application of culture supernatant of human umbilical cord mesenchymal stem cells (hUCMScs) and ciprofloxacin on Staphylococcus aureus (SA) in vitro. Methods: hUCMScs were isolated from umbilical cord tissues of full-term healthy fetuses after cesarean section and then cultured. Cells in the third passage were chosen for the use of experiment after identification. SA strains isolated from wounds of burn patients in our burn wards were used in the following experiment. Cells were divided into 0, 10, 100 and 1,000 ng/ml lipopolysaccharide (LPS) groups by use of the random number table (similarly hereinafter). Cells were cultured with culture medium containing mesenchymal stem cells (MScs) after being treated with medium containing corresponding mass concen-trations of LPS for 12 h. At post culture hour (PCH) 6, 12 and 24, 6 wells of culture supernatant of cells in each group were obtained to measure the content of LL-37 with enzyme-linked immunosorbent assay (ELISA). Ninety blood agar culture plates were divided into ciprofloxacin control group (CC), ciprofloxacin + supernatant group (cs), and ciprofloxacin + supernatant+ LL-37 antibody group (csL), with 30 blood agar culture plates in each group. Blood agar culture plates in group CC were coated with 1.5 × 108 colony forming unit (CFU)/ml bacteria solution prepared with normal saline. Blood agar culture plates in group cs were coated with 1.5 × 108 CFU/ml bacteria solution prepared with normal saline and hUCMSC culture supernatant (cultured by MSC culture medium, the same below) in double volume of normal saline. Blood agar culture plates in group csL were coated with 1.5 × 108 CFU/ml bacteria solution prepared with normal saline, hUCMSC culture supernatant in double volume of normal saline, and 2.6 μL of LL-37 antibodies at the concentration of 2 μg/ml. At PCH 12, 24 and 48, 10 blood agar culture plates were taken out from each group to observe the distribution of SA col

baCKGROUND Adrenocorticotropic hormone(ACTH)-independent Cushing's syndrome(cs) is mostly due to unilateral tumors, with bilateral tumors rarely reported. Its common causes include primary pigmented nodular adrenocortical disease,ACTH-independent macronodular adrenal hyperplasia, and bilateral adrenocortical adenomas(baAs) or carcinomas. baAs causing ACTHindependent cs are rare; up to now, fewer than 40 baA cases have been reported. The accurate diagnosis and evaluation of baAs are critical for determining optimal treatment options. Adrenal vein sampling(AVS) is a good way to diagnose ACTH-independent *** SUMMARY A 31-year-old woman had a typical appearance of cs. The oral glucose tolerance test showed impaired glucose tolerance and obviously increased insulin and Cpeptide levels. Her baseline serum cortisol and urine free cortisol were elevated and did not show either a circadian rhythm or suppression with dexamethasone administration. The peripheral 1-deamino-8-D-arginine-vasopressin(DDVAP)stimulation test showed a delay of the peak level, which was 1.05 times as high as the baseline level. Bilateral AVS results suggested the possibility of *** computed tomography showed bilateral adrenal adenomas with atrophic adrenal glands(right: 3.1 cm × 2.0 cm × 1.9 cm; left: 2.2 cm × 1.9 cm × 2.1 cm). Magnetic resonance imaging of the pituitary gland demonstrated normal findings. A left adenomectomy by retroperitoneoscopy was performed first,followed by resection of the right-side adrenal mass 3 mo later. Biopsy results of both adenomas showed cortical tumors. Evaluations of ACTH and cortisol showed a significant decrease after left adenomectomy but could still not be suppressed, and the circadian rhythm was absent. Following bilateral adenomectomy, this patient has been administered with prednisone until now,all of her symptoms were alleviated, and she had normal blood pressure without edema in either of her lower *** baAs causing ACTH-inde

Introduction Hypothyroidism increases the risk of cardiovascular complications in patients scheduled for coronary artery bypass grafting. Atrial fibrillation is one of its cardiac complications. Case Report Our 45-year-old male patient was admitted to the Emergency Medicine Clinic of our hospital with chest pain that started in the left arm and extended to the chin 2 days ago. It was noted that the patient had hypothyroidism, but did not have any medication for the disease. On physical examination, dry and pale skin, sparse coarse hair, non-pitting edema were diagnosed with acute coronary artery disease. No signs of ischemia were observed on the ECG at the time of admission, but bradycardic sinus rhythm was recorded. The patient was started to be followed up with the diagnosis of NON-ST myocardial infarction. Nitroglycerin 0.25 - 2 mcgr/h and morphine 2 mg were administered intravenously to the patient whose anginal complaints continued after admission. Anginal complaint continued was operated in 1:1 mode by attaching an intraaortic balloon pump (Maquet Sensation 7Fr 40 cc, Datascope cs300 console) via the left femoral artery. Surgery procedure: The patient was performed with median sternotomi (aortic, two-stage cannulation). While the patient was cooled to 32 degrees and given blood cardioplegia (St. Thomas II) and applied topical cold. After distal anastomoses were performed with saphenous vein graft. Total cross-clamp time was 60 min. Epinephrine was given for bradycardia sinus rhythm. No cardiovascular complications were encountered while being followed in the intensive care unit. The patient was discharged on the 6th postoperative day. Conlucion: Our case, who was taken to emergency CABG operation with myxedema, was discharged without any cardiovascular, respiratory or metabolic complications both in the perioperative and postoperative periods. In this case, the major stress caused by cardiovascular surgery was successfully overcome by both the cardiovascular s

AIM： To examine the effect of acute infection caused by herpesvirus （pseudorabies virus, PRV） on pancreatic ductal secretion. METHODS： The virulent ba-DupGreen （BDG） and non- virulent Ka-RREp01acgfp （KEG） genetically modified strains of PRV were used in this study and both of them contain the gene for green fluorescent protein （GFP）. Small intra/ interlobular ducts were infected with BDG virus （10^7 PFU/mL for 6 h） or with KEG virus （10^10 PFU/mL for 6 h）, while non-infected ducts were incubated only with the culture media. The ducts were then cultured for a further 18 h. The rate of HCO3 secretion [base efflux -λ（B）] was determined from the buffering capacity of the cells and the initial rate of intracellular acidification （1） after sudden blockage of basolateral base loaders with dihydro-4,4,- diisothiocyanatostilbene-2,2,-disulfonic acid （500 μmol/L） and amiloride （200 μmol/L）, and （2） after alkali loading the ducts by exposure to NH4Cl. All the experiments were performed in HCO3-buffered Ringer solution at 37 ℃ （n = 5 ducts for each experimental condition）. Viral structural proteins were visualized by immunohistochemistry. Virallyencoded GFP and immunofluorescence signals were recorded by a confocal laser scanning microscope.RESULTS： The BDG virus infected the majority of accessible cells of the duct as judged by the appearance of GFP and viral anUgens in the ductal cells. KEG virus caused a similarly high efficiency of infection. After blockage of basolateral base loaders, BDG infection significantly elevated -λB-） 24 h after the infection, compared to the non-infected group. However, KEG infection did not modify -λB-）. After alkali loading the ducts, -λB-） was significantly elevated in the BDG group compared to the control group 24 h after the infection. As we found with the inhibitor stop method, no change was observed in the group KEG compared to the non-infected group. CONCLUSION： Incubation with the BDG or KEG strains of PRV results in an effective i

针对时延估计问题中压缩感知类算法现有测量矩阵需要大量数据存储量的问题,提出了一种基于渐进添边的准循环压缩感知时延估计算法,实现了稀疏测量矩阵条件下接收信号时延的准确估计.该算法首先建立压缩感知与最大似然译码之间的理论桥梁,然后推导基于低密度奇偶校验码的测量矩阵的设计准则,引入渐进添边的思想构造具有准循环结构的稀疏测量矩阵,最后利用正交匹配追踪算法正确估计出时延.对本文算法的计算复杂度与测量矩阵的数据存储量进行理论分析.仿真结果表明,所提算法在测量矩阵维数相同的条件下正确重构概率高于高斯随机矩阵和随机奇偶校验测量矩阵,相比于随机奇偶校验矩阵,在数据存储量相等的条件下,以较少的计算复杂度代价得到了重构概率的较大提高.

World Journal of Cardiovascular Diseases 2023年第7期13卷 349-358页

作者： Khadidiatou Dia Waly Niang Mboup Djibril Marie ba Serigne Cheikh Tidiane Ndao Mame Madjiguene Ka Rabab Yassine Demba Ware balde Mouhamed Cherif Mboup Department of Cardiology Hospital Principal of Dakar Dakar Senegal Department of Cardiology Military Hospital of Ouakam Dakar Senegal

background: Heart failure is a major public health challenge in sub-Saharan Africa. In patients with chronic Heart Failure and cardiac desynchrony, studies have suggested that cardiac resynchronization, can improve cardiac function and the quality of life of patients. However, in Sub-Saharan Africa, very few studies have been done on cardiac resynchronization which is in its infancy. The aim of this study is to report the local data from our hospital. Method: It was a transversal, descriptive and analytical study conducted from November 2019 to September 2022 at the Cardiology Department of the Principal Hospital of Dakar. Results: Twelve patients were implanted for Cardiac Resynchronization Therapy (CRT). The sex ratio was 8 males/4 females. The average age was 67 ± 11 years. Ten patients had non-ischemic heart disease and the two others had ischemic one. All of them had NYHA III or IV scores before CRT. The Quality of Life (QOL) was judged as poor by all of the patients. The average duration of QRS was 156 ± 9 ms. 27.9% ± 5% was the mean Left Ventricular ejection fraction (LVEF). Complications occur in 3/12 patients (25%). It was one cs vein dissection, one micro LV lead dislodgement and one phrenic nerve stimulation. Nine patients, who were considered as responders, had an improvement of QOL and NYHA, the LVEF increased and the end-diastolic dimension, and the duration of the QRS interval all decreased. Two patients do not respond and one (1) who had permanent atrial fibrillation, was a secondary responder after an atrioventricular junction ablation. Conclusion: Cardiac resynchronization is a therapy that improves the QOL of patients, the LVEF and reduces the duration of the QRS interval. However, this procedure is not without risk of complications. In sub-Saharan Africa, the major challenge is to improve the financial accessibility of this therapy for the population.
