Dynamic interaction nursing intervention on functional rehabilitation and self-care ability of patients after aneurysm surgery.

BACKGROUND: Nursing practices based on the dynamic interaction model have been shown to be superior to generic nursing practices. However, whether this model is effective in patients recovering from intracranial aneurysm surgery is not well studied. AIM: To investigate the effect of nursing based on a dynamic interaction model on functional rehabilitation of patients after aneurysm surgery. METHODS: A total of 86 cases in our hospital with intracranial aneurysm from April 2019 to April 2021, were selected and divided into the study group and the control group, with 43 patients in each group. The control group received routine nursing, and the research group received nursing intervention based on a dynamic interaction model. The daily living ability (activities of daily living, ADL), cognitive function (Simple Intelligent Mental State Scale, MMSE), quality of life (Generic Quality of Life Inventory-74, GQOL-74), self-care ability (Exercise of Self-Care Agency scale), incidence of complications, and nursing satisfaction were recorded before and after intervention. RESULTS: Before intervention, ADL (52.09 ± 6.44), MMSE (18.03 ± 4.11), and GQOL-74 (53.68 ± 4.34) scores in the study group were not significantly different from those in the control group (ADL: 50.97 ± 7.32, MMSE: 17.59 ± 3.82, GQOL-74: 55.06 ± 3.98) (P > 0.05). After intervention, ADL (86.12 ± 5.07), MMSE (26.64 ± 2.66), and GQOL-74 (83.13 ± 5.67) scores in the study group were higher than those in the control group (ADL: 79.81 ± 6.35, MMSE: 24.51 ± 3.00, and GQOL-74: 77.96 ± 6.27) (P < 0.05). Before intervention, self-concept (17.46 ± 4.44), self-care skills (25.22 ± 4.20), self-care knowledge (22.35 ± 4.74), and self-care responsibility (15.06 ± 3.29) scores in the study group was similar to those in the control group (self-concept: 16.89 ± 5.53, self-care skills: 24.59 ± 4.46, self-care knowledge: 21.80 ± 3.61, and self-care responsibility: 14.83 ± 3.11) (P > 0.05). After the intervention, self-concept (26.01 ± 3.18), self-care skills (37.68 ± 6.05), self-care knowledge (45.56 ± 5.83), and self-care responsibility (22.01 ± 3.77) scores in the study group were higher than those in the control group (self-concept: 22.97 ± 3.46, self-care skills: 33.02 ± 5.65, self-care skills knowledge: 36.81 ± 5.54, and self-care responsibility: 17.97 ± 3.56 points) (P < 0.05). The incidence of complications in the study group (4.65%) was lower than that in the control group (18.60%) (P < 0.05). Nursing satisfaction in the study group (95.35%) was higher than that in the control group (81.40%) (P < 0.05). CONCLUSION: Nursing intervention based on a dynamic interaction model can improve postoperative cognitive function, daily living ability, self-care ability, quality of life, and patient satisfaction, while reducing the risk of complications.

MicroRNA-96 Regulates Apoptosis by Targeting PDCD4 in Human Glioma Cells.

Glioblastoma multiforme, the most common and aggressive form of primary brain tumor, presents a dismal prognosis. MicroRNAs play a critical role in the initiation, progression, and metastasis of cancer; however, the potential biological role of miRNAs in glioblastoma multiforme remains largely unknown. In our study, we found that microRNA-96 is upregulated in glioma tissues than in normal human brains. Transfection of microRNA-96 mimics into glioma cells significantly decreases apoptosis by suppressing PDCD4, a well-known tumor suppressor that is involved in apoptosis. In contrast, knockdown of microRNA-96 enhanced apoptosis. In vivo, microRNA-96 overexpression inhibits the apoptosis and increases tumor growth. These data suggest that microRNA-96 is a potential molecular target for glioma treatment.

[Electrophysiology of cardiocytes in ligament of Marshall of canine].

OBJECTIVE: To investigate electrophysiology of cardiocytes in ligament of Marshall. METHODS: The single cardiocytes obtained from ligament of Marshall were direct observed under inverted microscope. The cardiocyte action potential and current density of I(Na), I(Ca), L, I(to), I(K) and I(K1) were researched by whole-cell patch-clamp techniques. RESULTS: There were two different cardiomyocytes in ligament of Marshall, one was rod shape, the other was short-rectangle shape. The short-rectangle myocyte was short and thick; the rod myocyte was long and thin. The short-rectangle myocyte was more than rod myocyte. The length/width rate of short-rectangle myocyte was less than that of rod myocyte (2.99 +/- 0.95 vs 12.05 +/- 2.41, P < 0.01). The action potential of ligament myocytes was similar to fast responsive cells. The action potential amplitude (APA) and duration (APD) of short-rectangle cells were less than those in rod cells. APA (mV), APD(50) (ms) and APD(90) (ms) were respectively 80.02 +/- 3.68 vs 91.72 +/- 7.56, 69.62 +/- 6.33 vs 83.14 +/- 3.66 and 107.55 +/- 4.25 vs 144.00 +/- 5.15, P < 0.05. The ion current density of I(Na), I(Ca), L, I(to), I(K1) was different between the two kind cells. CONCLUSIONS: There are two different cardiocytes in ligament of Marshall. The action potential and ion current density of I(Na), I(Ca), L, I(to), I(K1) are different between the two kind cardiocytes.
