background The hemodynamics and oxygenation severely fluctuated during the offpump coronary artery bypass grafting (OPCABG) This study aimed at investigating whether or not nicardipine combined with esmolol (1∶10) can maintain systemic and tissue oxygenation during OPCABGMethods Twenty patients scheduled for OPCABG were divided ramdomly into Group nicardipine (N) and Group nitroglycerine (X) respectively combined with esmolol (E) (Dosage ratio: 1 to 10) (Group N+E and Group X+E) with 10 patients in each group The mixed solution of N+E or X+E were titrated to maintain mean arterial blood pressure between 70 and 80 mmhg following anesthesia induction The variables of hemodynamics, arterial blood lactate content (Lac) and gastric intramucosal partial pressure of carbon dioxide were measured at the following time points: after induction of anesthesia (T1), prerevascularization (T2), grafting of left anterior descending (T3), right coronary descending (T4) and left coronary circumflexus branches (T5), postrevascularization (T6), the end of operation (T7) The delivery of oxygen (DO2), consumption of oxygen (VO2) and gastric intramucosal ph (phi) were calculatedResults The cardiac index (CI) in Group N+E was significantly increased (Ph T1 during OPCABG, while it was mildly decreased in Group X+E The stroke volumes at T4, T5 in Group N+E and at T3T6 in Group X+E were significantly decreased (Phe systemic vascular resistance indices in Group N+E were significantly decreased as compared with T1 (Phe heart rates in these two Groups were significantly elevated intraoperatively (Phe DO2 after the infusion of N+E was significantly increased (Phe Lac were within the normal range But the DO2 in Group X+E was decreased throughout the procedure, reaching significant level at T5 (Phe Lac was significantly increased beyond normal range (Phe p

目的探讨西藏农村项目点中小学生生长迟缓流行现状及其与室外活动时间的关联性。方法利用2019年西藏农村义务教育学生营养改善计划营养监测数据,采用随机抽样原则,抽取国家重点监测县巴宜区、南木林县的9~18岁学生共934人进行问卷调查和体格测量。采用多因素Logistic模型、亚组分析室外活动时间对生长迟缓的影响。结果2019年西藏农村项目点中小学生生长迟缓率为6.75%,59.90%的西藏农村项目点中小学生每天室外活动时间不足1 h。多因素Logistic模型显示,调整个人特征、家庭情况和社会行为因素后,与室外活动时间不足1 h相比,室外活动时间1 h及以上的西藏农村项目点中小学生生长迟缓的OR值为0.39(95%CI:0.20~0.76)。亚组分析显示,家庭人口为2~6人的OR值为0.14(95%CI:0.04~0.48),家庭人口为7人及以上的OR值为0.83(95%CI:0.34~2.01)。营养知识答对0~3个题的OR值为0.93(95%CI:0.37~2.34),答对4~6题的OR值为0.13(95%CI:0.04~0.44)。室外活动时间是生长迟缓的影响因素,亚组人群中家庭人口数与营养知识了解情况差异有统计学意义(P<0.05)。结论西藏农村项目点中小学生室外活动时间与生长迟缓患病风险相关,在鼓励和倡导学生增加室外活动时间的同时,要关注家庭人口较多、营养知识了解较少的学生。

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

背景:塞内加尔达喀尔国家结核病参比实验室。目的:比较荧光显微镜和明视野显微镜检查抗酸杆菌的结果。方法:1996年1月至1998年6月期间2630份痰标本被同时制备2种涂片,在1000倍物镜下分别进行萋-尼氏染色和荧光显微术检查,并应用这两种方法同时检查一例标本的68张涂片来确定判断一张涂片为阴性所需的检查时间。结果:诊断和随访检查时两者的符合率分别为96.9％和92.3％。当标本中每100个视野至少10条菌时,两者的检出率相似,但当标本中每100个视野少于10条菌时,荧光显微术的检出率较高。在同倍物镜下,荧光显微术判断一张涂片为阴性所需的检查时间平均为3分34秒,而萋-尼氏染色技术需7分44秒。结论:两者的检查结果非常相似。对于含菌量少的病例,荧光显微镜似比明视野显微镜的检出率更高,而且所需检查时间少一半多。

Introduction: Little is known through the literature about dental status of patients seen in cardiology department, motivating this study which aims to assess most dental indices of outpatients and the need for periodontal treatment. Methodology: It was a cross-sectional study from November 2016 to April 2017 in the cardiology outpatient unit of the University hospital Gabriel Touré (Uh-GT) in bamako. Included were all patients with minimum 24 teeth and willing to be involved in the study. history, cardiovascular parameters and dental examination by a resident in Odontostomatology were performed for each patient. Data were analyzed using SPSS 18, quantitative as means and standard deviation (SD) and categorical as proportions. Khi-2 Test, analysis of variance were applied with a significance level set at 0.05. All patients give their verbal consent after being informed about the procedures in the study. Results: Our sample involved 100 patients (66% female, mean age of 54.12 ± 16.150 and patients ≥ 60 years most represented with 50% for male and 37.9 for female patients. Tooth brush use was practiced by 100% and 98.5% respectively for male and female patients and twice daily brushing by 97.1% of male and 97% of female patients. Brushing duration was less than 3 minutes for 35.3% and 31.8% of respectively male and female patients. Plaque index and calculus index were in the male group with respectively 0.79 and 1.06 for male and 0.63 and 0.79 for female (p = 0.047 and 0.020). Mean Decayed Missed and Filled Teeth (DFMT) index showed a significantly increase from 0.22 in the age group under 30 to 0.68 for that other 60 years. Only 2.9% and 9.1% of respectively male and female patients had community paradontal index for treatment needs (CPITN) classe 0. The need for treatment was TN1 meaning instruction to an oral cavity hygiene, similar for both sex (55.9 and 57.6 respectively for male and female patients) and highest in the age-group 30 - 44 increased to 70%.

Open Journal of Nephrology 2022年第4期12卷 361-368页

Introduction: This study aimed to assess the prevalence of Intra-dialytic hypotension (IDh) according to the European Best Practice Guidelines (EBPG) definition in relation to the number of haemodialysis sessions and the number of chronic haemodialysis patients and to identify its associated factors. Patients and Methods: We conducted an observational, multicentre and looking-forward study of descriptive and analytical purposes over a 4-week period. The study included all patients with regular chronic haemodialysis with at least two sessions per week and a duration of 180 minutes, who consented to participate in the study and were over 15 years of age. Data collection was done with pre-established forms. The following data were collected: blood pressure before each session, at 30, 60, 120, 180 and 240 minutes of each session;socio-demographic data;dialysis data;clinical, paraclinical, therapeutic data and nursing interventions. Results: The mean age of the patients was 43.84 ± 12.10 years. Among 568 haemodialysis sessions recorded in 50 patients, IDh was noted in 12 haemodialysis sessions, representing a prevalence of 2.11%. Fatigue was found in 5 sessions with IDh episodes (41.66%) followed by yawning (25%), nausea ± vomiting (16.66%) and cramps (16.66%). As nursing interventions, Trendelenburg position and normal saline administration were performed in all IDh episodes. high blood pressure, inter-dialytic weight gain greater than 3 kg, Uf/h > 10 ml/kg/h, anaemia and hypoalbuminaemia were associated with the occurrence of IDh. Conclusion: The prevalence of IDh according to the EBPG definition is low. however, it is an important cause of morbidity and mortality, especially cardiovascular involvement, and the factors associated with its presence have been clearly identified.
