Clinical value of precise rehabilitation nursing in management of cerebral infarction

BACKGROUND Cerebral infarction,previously referred to as cerebral infarction or ischemic stroke,refers to the localized brain tissue experiencing ischemic necrosis or softening due to disorders in brain blood supply,ischemia,and hypoxia.The precision rehabilitation nursing model for chronic disease management is a continuous,fixed,orderly,and efficient nursing model aimed at standardizing the clinical nursing process,reducing the wastage of medical resources,and improving the quality of medical services.AIM To analyze the value of a precise rehabilitation nursing model for chronic disease management in patients with cerebral infarction.METHODS Patients(n=124)admitted to our hospital with cerebral infarction between November 2019 and November 2021 were enrolled as the study subjects.The random number table method was used to divide them into a conventional nursing intervention group(n=61)and a model nursing intervention group(n=63).Changes in the nursing index for the two groups were compared after conventional nursing intervention and precise rehabilitation intervention nursing for chronic disease management.RESULTS Compared with the conventional intervention group,the model intervention group had a shorter time to clinical symptom relief(P<0.05),lower Hamilton Anxiety Scale and Hamilton Depression Scale scores,a lower incidence of total complications(P<0.05),a higher disease knowledge mastery rate,higher safety and quality,and a higher overall nursing satisfaction rate(P<0.05).CONCLUSION The precision rehabilitation nursing model for chronic disease management improves the clinical symptoms of patients with cerebral infarction,reducing the incidence of total complications and improving the clinical outcome of patients,and is worthy of application in clinical practice.

Effect of psychological nursing intervention on anxiety level and quality of life in patients with gastrointestinal peptic ulcer

BACKGROUND Peptic ulcer is a common gastrointestinal disease,and psychological intervention has an important influence on its occurrence and development.AIM To investigate the effect of psychological nursing intervention on the anxiety level and quality of life of patients with gastrointestinal peptic ulcers.METHODS Two groups of patients with peptic ulcer were selected from January to December 2012,with 60 cases in each group,and psychological nursing intervention and routine treatment were respectively performed.Psychological nursing interven-tions include cognitive behavioral therapy,psychological support and relaxation training.Self-rating anxiety scale(SAS)and quality of life questionnaire were used to evaluate the anxiety level and quality of life of patients before,during and after treatment.RESULTS The SAS scores of the experimental group significantly decreased over the course of treatment,from 52.3 before treatment to 30.5 after treatment,while SAS scores of the control group did not change significantly.Meanwhile,the experimental group's quality of life score(SF-36)significantly improved over the course of treatment,from 65.2 to 85.2,while the control group remained stable.Further analysis showed that sex and age had no significant influence on the effect of psychotherapy.Both men and women,young and old,showed similar trends in anxiety relief and improved quality of life after treatment.CONCLUSION Psychological nursing-based intervention program has a positive effect on the anxiety level and quality of life of patients with gastrointestinal peptic ulcer.

红芪多糖“脱蛋白-大孔吸附树脂”的纯化富集工艺考察

目的研究红芪多糖(HPS)标准提取物,筛选优化其“脱蛋白-大孔吸附树脂纯化富集”的工艺方法与工艺参数。方法以蛋白脱除率和多糖损失率为指标,比较4种不同方法的脱蛋白效果,并对筛选出的方法进行工艺参数优化;以吸附量和吸附率为指标,考察4种型号大孔吸附树脂(AB-8、D-101、NKA-9、X-5)对HPS的纯化富集效果,并进行相关工艺参数优化;采用苯酚硫酸法和考马斯亮兰法分别测定多糖和蛋白质含量;采用紫外分光光度(UV)和红外光谱(IR)法比较纯化前后多糖的基本特征。结∶果筛选出的脱蛋白方法为Sevag法,优选的树脂为AB-8大孔吸附树脂。通过工艺参数优选,确定的纯化工艺为:10 mg·mL^(-1)粗多糖水溶液,以1/2倍体积氯仿^(-1),∶v/v)混合试剂进行脱蛋白操作2次;除去残留有机溶剂后,以质量浓度为1.5 mg·mL^(-1)的水溶液,上预处理好的AB-8大孔吸附树脂柱[树脂量(g)与上样体10]∶,以2.0 mL·min^(-1)流速循环上样2次,动态吸附后再静态吸附6~8 h,后以30%乙醇1.0 mL·min^(-1)进行洗脱,至洗脱液无明显碱性酒石酸铜反应,收集洗脱液浓缩至与原药1冲洗沉淀,即得HPS。结论验证试验表明,经本工艺纯化富集后,所得HPS样品纯度提高了1.27倍;UV在260,280 nm处未见蛋白质吸收峰;IR表现出更突出的多糖结构特征吸收峰,说明纯化过程有效且未对HPS主要结构产生影响。优选出的HPS脱蛋白和大孔树脂纯化工艺稳定可行,重复性较好,使多糖得到较好的纯化富集,为HPS标准提取物的形成以及其能成为制剂科学化原料药提供了研究基础。

目的比较腹腔镜肾部分切除术(LPN)和腹腔镜冷冻消融(LCA)治疗肾皮质小肿块(<3.5 cm)的围手术期情况和短期临床结局。方法共纳入167例患者。其中,92例95处病灶接受LPN,75例患者91处病灶接受LCA。比较两组患者围手术期和临床结局。结果LPN和LCA组肿块平均直径、术前、术后肌酐水平无差异(P=0.495,P=0.953,P=0.101)。LPN组平均年龄低于LCA组[(58.8±3.2)和(69.2±4.7)岁,P<0.01],LPN组平均失血量更高[(168.4±17.2)和(66.1±8.3)ml,P=0.005],平均手术时间更长[(151.6±13.2)和(128.6±10.8)min,P=0.001]。LCA组和LPN组中分别发生6种并发症。LPN和LCA组中位随访时间分别为(21.8±4.8)和(14.2±1.3)个月(P<0.01)。LCA组2例患者复发,LPN组1例患者复发。结论在短期随访中,LPN和LCA治疗肾皮质小肿块的疗效无差异,LCA失血量较少、手术时间较短,且并发症发生率较低。

Identification of Serum Exosomal MicroRNA Expression Profiling in Menopausal Females with Osteoporosis by High-throughput Sequencing

Estrogen deficiency,which mainly occurs in postmenopausal women,is a primary reason for osteoporosis in clinical diagnosis.However,the molecular regulation of osteoporosis in menopausal females is still not adequately explained in the literature,with the diagnosis and treatment for osteoporosis being limited.Herein,exosomal microRNAs(miRNAs)were used to evaluate their diagnosis and prediction effects in menopausal females with osteoporosis.In this study,6 menopausal females without osteoporosis and 12 menopausal females with osteoporosis were enrolled.The serum exosomes were isolated,and the miRNA expression was detected by miRNA high-throughput sequencing.Exosomal miRNA effects were analyzed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses.The miRNA-targeted genes were evaluated by Targetscan 7.2 and the protein-protein interactions(PPI)by STRING.Hub genes were analyzed by the CytoHubba app of Cytoscape.The results showed that 191 aberrant miRNAs were found in the group of menopausal females with osteoporosis,including 72 upregulated miRNAs and 121 downregulated miRNAs.Aberrant miRNAs were involved in many signaling pathways,such as the Wnt,MAPK,and Hippo pathways.Based on PPI network analysis,FBXL3,FBXL13,COPS2,UBE2D3,DCUN1D1,DCUN1D4,CUL3,FBXO22,ASB6,and COMMD2 were the 10 most notable genes in the PPI network.In conclusion,aberrant serum exosomal miRNAs were associated with an altered risk of osteoporosis in menopausal females and may act as potential biomarkers for the prediction of risk of osteoporosis in menopausal females.
