ABSTRACT
@# Objective To analyze the risk factors for postoperative length of stay (PLOS) after mediastinal tumor resection by robot-assisted non-endotracheal intubation and to optimize the perioperative process. Methods The clinical data of patients who underwent Da Vinci robot-assisted mediastinal tumor resection with non-endotracheal intubation at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from 2016 to 2019 were retrospectively analyzed. According to the median PLOS, the patients were divided into two groups. The univariate analysis and multivariate logistic regression were used to analyze risk factors for prolonged PLOS (longer than median PLOS). Results A total of 190 patients were enrolled, including 92 males and 98 females with a median age of 51.5 (41.0, 59.0) years. The median PLOS of all patients was 3.0 (2.0, 4.0) d. There were 71 patients in the PLOS>3 d group and 119 patients in the PLOS≤3 d group. Multivariate logistic regression showed that indwelled thoracic catheter [OR=11.852, 95%CI (2.384, 58.912), P=0.003], preoperative symptoms of muscle weakness [OR=4.814, 95%CI (1.337, 17.337), P=0.016] and postoperative visual analogue scale>5 points [OR=6.696, 95%CI (3.033, 14.783), P<0.001] were independent factors for prolonged PLOS. Totally no tube (TNT) allowed patients to be discharged on the first day after surgery. Conclusion Robot-assisted mediastinal tumor resection with non-endotracheal intubation can promote rapid recovery. The methods of optimizing perioperative process are TNT, controlling muscle weakness symptoms and postoperative pain relief.
ABSTRACT
@#Objective To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.
ABSTRACT
Heated humidified high flow nasal cannula oxygen therapy (HFNC) has the characteristics of improving the work of breathing,creating the effect of positive end-expiratory pressure,being setted up easily,well tolerated by patients and high safety.At present,it has been widely used in neonatal respiratory support,but lack of its extensive use and research in infants and children.HFNC is suitable for use in infants with viral bronchiolitis,pneumonia,asthma,ARDS,and postextubation respiratory support from the aspect of the mechanism of action of HFNC and the pediatric physiology.HFNC should be the preferred mode of conventional oxygen therapy in pediatrics.
ABSTRACT
Objective To investigate the correlation of Bax and apoptosis in enterocytes of neonatal rats with necrotizing enterocolitis (NEC).Methods Forty-eight neonatal rats (1 day) were randomly divided into control group (n =24) and NEC model group (n =24) by use of odd and even.The rats in control group were maternal breast-fed.The rats in NEC model group were separated from their mothers.To be given formula feeding,cold exposure after hypoxic-reoxygenation treatment.The intestinal tissue located at the boundary of ileum and caecum of two groups were gained on the 24 h,48 h and 72 h with which that all rats were sacrificed by cutting neck.Section of intestinal tissue were stained with immunohistochemistry to detect the expression of Bax and were stained with TdT mediated dUTP nick end labeling(TUNEL) to evaluate the apoptosis in each group.Results The integrate optical density (IOD) value of expression of Bax in the NEC model group began to increase on the 24 h [(1 005.06-± 11.96) IOD] and reached the summit on the 72 h [(3 340.66 ±68.72)] compared with the control group[(666.55 ± 15.77)IOD].A few of TUNEL positive cells began to increase with time dependence.A lot of TUNEL positive cells could be found in NEC model group on the 24 h [(15.04 ± 0.24) ％],and the apoptotic index reached the peak on the 72 h [(35.65 ±0.61) ％] compared with the control group[(4.73 ±0.04) ％,P ＜0.01]-There was a significantly positive correlation between the cell apoptosis and the ratio change of Bax in NEC model group (r =0.94,P ＜ 0.01).Conclusion There is a significantly positive correlation between the cell apoptosis and the ratio change of Bax in enterocytes of neonatal rats with NEC.The cell apoptosis in enterocytes of neonatal rats with NEC maybe be induced by Bax.
ABSTRACT
OBJECTIVE@#To investigate the correlation between serum vitamin D levels and index of glucose and lipid metabolism in postmenopausal women with type 2 diabetes mellitus (T2DM).@*METHODS@#A total of 44 postmenopausal women with T2DM and 41 healthy postmenopausal women were matched with age, body mass index and menopausal duration. The serum vitamin D was detected by enzyme-linked immuno-sorbent assay (ELISA).@*RESULTS@#Compared with the control group, the level of 25(OH)D3 in postmenopausal women with T2DM was lower, with no statistical significance. Multiple regression analysis revealed that only BMI(bj'=-0.372, P<0.05) was independently related to 25(OH)D3 with statistical significance. The percentages of 25(OH)D3 deficiency in all subjects in the control group and in the T2DM group were 84.7%, 80.5%, and 88.6%, respectively. The 25(OH)D3 deficiency in the T2DM group was more prevalent than that in the control group, with no statistical difference (P=0.372). The binary logistic regression analysis showed the serum 25(OH)D3 level was not related to the risk of diabetes.@*CONCLUSION@#Compared with the control group, a lower 25(OH)D3 level and a higher rate of 25(OH)D3 deficiency is found in T2DM subjects. When rectified by BMI, these is no significant difference. In postmenopausal women, hypovitaminosis D is associated with obesity and dyslipidemia, but not with the risk of T2DM.
