Objective:To explore the effect of therapeutic communication on infusion safety, disease uncertainty, coping styles, anxiety and depression in patients with emergency infusion.Methods:A total of 126 patients treated with infusion patients in emergency department in Jiangsu Provincial People's Hospital, the First Affiliated Hospital of Nanjing Medical University from July 2019 to December 2019 were selected and divided into two groups by random digits table method with 63 cases in each group. Patients in the control group received routine nursing, and patients in the intervention group received therapeutic communication nursing intervention on this basis. The incidence of adverse events of infusion during the intervention of the two groups of patients was observed. The disease uncertainty, coping styles, anxiety and depression were evaluated by Mishel's Uncertainty in Illness Scale (MUIS), Medical Coping Mode Questionnaire (MCMQ), Self-rating Anxiety Scale (SAS) and Self-rating Depressive Scale (SDS) before and after intervention.Results:The final collection of 109 patients with complete questionnaire, the recovery rate was 86.51% (109/126), including 55 cases in the intervention group, 54 cases in the control group. The incidence of adverse events of infusion was 16.36%(9/55) in the intervention group and 29.63%(16/54) in the control group, and there was significant difference( χ2 value was 5.057, P<0.05). There was no significant difference in the score of MUIS, MCMQ, SAS, SDS before the intervention between the two groups ( P>0.05). After the intervention, the uncertainty, unpredictability, lack of information and complexity dimension of the intervention group patients' MUIS scores were respectively (17.76 ± 2.49), (12.03 ± 2.51), (11.82 ± 2.12), (11.74 ± 2.24), which were lower than those in the control group (24.72 ± 2.94), (16.31 ± 2.27), (16.13 ± 2.51), (15.39 ± 2.31), the differences were significant( t values were -13.346- -8.375, P<0.05). The confront score of the intervention group patients' MCMQ was (19.13 ± 2.62) higher than that in the control group(13.79 ± 1.96), the avoidance and yield scores were respectively (8.71 ± 1.34), (9.81 ± 1.17), which were lower than those in the control group (14.57 ± 1.93), (15.12 ± 1.86), the differences were significant( t values were 12.031, -18.441, -17.875, P<0.05). The scores of SAS and SDS in the intervention group were (29.43 ± 3.62), (27.67 ± 3.11) respectively, which were lower than those in the control group (37.44 ± 5.31), (40.12 ± 4.92), the differences were significant( t values were -9.216, -15.821, P<0.05). Conclusions:Therapeutic communication can reduce the risk of emergency infusion, reduce the uncertainty of patients to the disease, improve patients' countermeasures to the disease, relieve patients' anxiety and depression, and improve the nursing quality of emergency infusion patients.

The aim of this study is to investigate the anti-inflammatory effect of the adenosine derivative N6-(3-hydroxylaniline) adenosine (WS070117M1) on cigarette smoke plus LPS (lipopolysaccharide)-induced chronic obstructive pulmonary disease (COPD) in mice and its mechanism. COPD model was established by exposing male BALB/c mice to cigarette smoke and challenged with LPS inhalation. Supernatants of bronchoalveolar lavage fluid (BALF) were harvested and IL-1β, IL-6, IL-8 and TGF-β1 levels were measured by ELISA (enzyme-linked immunesorbent assay). The number of total white blood cells and neutrophils in bronchoalveolar lavage fluid was counted separately. Lung tissue was stained with Mayer 's hematoxylin and eosin for histopathologic examination. pAMPKa protein expression and distribution of lung tissue were analyzed by immunohistochemistry method. In vitro, levels of AMPKα phosphorylation in phorbol-12- myristate-13-acetate (PMA) differentiated THP-1 cells was detected by immunohistochemistry, IL-8 level in supernatants of cigarette smoke condensate stimulating PMA differentiated THP-1 cells was measured by ELISA. The results showed that WS070117M1 treatment significantly activated AMPKa in the lung tissue. It also resulted in down regulation of IL-1β, IL-6, IL-8 and TGF-β1 levels in bronchoalveolar lavage fluid and IL-8 level in cigarette smoke condensate stimulating PMA differentiated THP-1 cells. In addition, WS070117M1 could inhibit the recruitment of total white blood cells and neutrophils. These results suggest that WS070117M1 may alleviate the airway inflammation by activating AMPK in the lung tissue.

AIM:To investigate the mechanism of lipotoxicity-associated apoptosis mediated by mitochondrial pathway in pancreatic β-cells. METHODS:The pancreatic β-cell line MIN6 cells were incubated respectively in serum-free DMEM medium with or without palmitate (0.1-0.5 mmol/L) for 24 h,followed by Hoechst 33258 staining. The activity of caspase 3 was assayed for determining apoptosis,transmission electron microscope was used for observing mitochondrial structure,and RT-PCR analysis was applied for detection of mRNA expression of bcl-2-associated X protein (bax),B-cell lymphoma 2 (bcl-2),sterol regulatory element binding transcription factor 1c (SREBP1c) and DNA-damage inducible transcript 3 (chop-10). RESULTS:Palmitate induced apoptosis of MIN6 cells and swelling of mitochondria. Palmitate also inhibited mRNA expression of bcl-2,whereas enhanced mRNA expression of bax,SREBP1c and chop-10. CONCLUSION:Palmitate induces apoptosis of pancreatic β-cells by promoting mitochondrial dysfunction,which is associated with abnormal expressions of bax,bcl-2,SREBP1c and chop-10.

Objective To explore the value of CT spinal angiography with 256 MSCT and fast dynamic contrast-enhanced 3D MR angiography (CE-MRA) at 3.0 T in the diagnosis of spinal vascular malformations by comparing with results of DSA and operation.MethodsSeventeen patients suspected of spinal vascular diseases by initial MR and clinical manifestations all underwent CT spinal angiography.Of them,10 patients underwent MRA,15 patients underwent DSA within 3-5 days,and 8 patients finally underwent surgical treatment.ResultsCTA examination clearly showed the abnormal vascular lesions in 16 of 17 cases,including 7 cases with the diagnosis of spinal dural arteriovenous fistula,7 cases of perimedullary arteriovenous fistula,and 2 cases of spinal arteriovenous malformations. The results were consistent with the diagnosis of DSA or surgery.One case was poorly diagnosed.The feeding vessels were correctly determined in 12 cases,and the level of fistulas were correctly displayed in 12 cases.The level of fistulas and feeding vessels were accurately showed in 7 of 10 cases with MRA,while the other 3 cases exhibited normal with DSA.ConclusionsSpinal angiography with 256 MSCT and CE-MRA at 3.0 T can clearly show the extent of spinal vascular malformations,feeding arteries and fistula location.They are safe,noninvasive,convinient and can shorten the time of DSA diagnosis and treatment.They play an important role in diagnosis and treatment of spinal vascular malformations and postoperative follow-up.
