ABSTRACT
Objective:To understand clinical effect of a homemade infants wrist hand thumb joint fixtures to prevent the unplanned extubation (UEX) in radial arterial puncture tube in children with congenital heart disease.Methods:From October 2016 to October 2019, 150 cases infants patients with simple congenital heart disease in cardiac surgery of the First Affiliated Hospital of University of Science and Technology of China were selected as the research objects, and the radial artery invasive manometric tube was routinely indwelling after operation. Subjects were randomly divided into observation group and control group, with 75 cases in each group. In the observation group, the wrist joint of children was fixed with homemade fixation device. The control group used conventional fixation methods to fix the wrist joint of infants. The incidence of pressure injury and unplanned extubation were compared between the two groups.Results:There was 1 case (1.33%) pressure injury in the observation group and 2 cases (2.67%) in the control group, and there was no statistical significance in the two groups ( P>0.05). The unplanned extubation rate of radial artery pressure tube occurred in 5 cases (6.67%) in the observation group, and lower than that in the control group (17/75, 22.67%) ( χ2=7.67, P<0.01). When children in the state of agitation and very agitation, the incidence of unplanned extubation rate in the observation group was 0 and 4.35%(1/23), lower than that in the control group 15.79%(6/38) and 35.00% (7/20), respectively ( χ2=6.19, 6.64, both P<0.05). With the extension of ICU time, the incidence of unplanned extubation rate was increased. The incidence of unplanned extubation rate was 4.76% (2/42) and 9.09% (3/33) in the observation group and 18.18%(8/44) and 29.03% (9/31) in the control group when ICU time was ≤24 h and>24 h, respectively. The difference was statistically significant ( χ2=5.51, 4.17, both P<0.05). Conclusions:The homemade wrist thumb joint fixtures device for infants does not increase the pressure injury of the fixed part, and can reduce the incidence of unplanned extubation of radial artery manometric tube in children with congenital heart disease.

ABSTRACT
OBJECTIVE:To establish the fingerprint of raw produc ts and different processed products of Pinellia pedatisecta , to determine the contents of 5 kinds of nucleosides ,and to compare the differences of components between the raw products and processed products. METHODS :P. pedatisecta raw products ,processed products by Processing Standard of Chinese Medicine in Henan Province (called“Standard processed product ”for short )and processed products by new integrated processing technology in the production area (called“new integrated processed product ”for short )were collected as investigation objects (12 batches of each). The determination was performed on SymmetryShield RP 18 column with mobile phase consisted of acetonitrile (A)-0.1% acetic acid aqueous water solution (B)(gradient elution )at the flow rate of 0.8 mL/min,with the column temperature of 30 ℃, the detection wavelength of 270 nm,and the injection volume of 15 µL. HPLC fingerprints of 3 kinds of P. pedatisecta samples were established by using Similarity Evaluation System of TCM Chromatographic Fingerprints (2004 A version ) ,and the similarity of fingerprints was evaluated. The chromatographic peaks were identified by comparing with the reference chromatogram. Five nucleosides (adenine,hypoxanthine,uridine,xanthine,inosine)were quantitatively analyzed. SPSS 21.0 software was used for cluster analysis of 36 batches of samples. RESULTS :The results of fingerprint and content determination met the relevant requirements. The similarity of 3 kinds of sample with their control fingerprint were all greater than 0.990. There were 22 common peaks in the raw products of P. pedatisecta ,and 16 common peaks were identified in the 2 kinds of processed products (the same 6 peaks disappeared from 2 kinds of processed products ). Fivecomponents were identified in 3 kinds of samples ,such as adenine(peak 3),hypoxanthine(peak 7),uridine(peak 8), 1064056472@qq.com xanthine(peak 9)and inosine (peak 11). Results of content determination showed that total contents of 5 kinds of nucleosides in 2 kinds of proc essed products were all· decreased;the contents of them in descending order w as raw product >new i ntegrated processed products >Standard processed products. Results of cluster analysis showed that 36 batches of samples could be clustered into 2 categories,i.e. raw product was clustered into one category and 2 kinds of processed products into other one . CONCLUSIONS :Established method is stable , feasible and suitable for the quality evaluation of raw products and different processed products of P. pedatisecta . Fingerprints have changed significantly and the total content of 5 kinds of nucleosides in P. pedatisecta are all decreased after processing ,but that of new integrated processed products is slightly higher than that of Standard processed products .
ABSTRACT
Objective By constructing the differential expression profile of lncRNA/mRNA in peripheral blood plasma of patients with Keshan disease (KSD) and dilated cardiomyopathy (DCM),to explore the commonality and characteristics of the two diseases in molecular mechanism.Methods Ten patients with chronic KSD were selected in the severe disease area of KSD in Shandong Province,and 10 cases of DCM and 10 healthy subjects (control group) were selected in non-KSD area.Blood of elbow vein was collected and plasma was separated.RNA-seq technology was used to construct the differential lncRNA/mRNA expression profile between KSD and control group,DCM and control group,and co-expression and specific expression of partial genes in KSD and DCM were analyzed through Wien analysis.The lncRNA-mRNA co-expression network maps of specific part of KSD,specific part of DCM and common part of the two diseases were constructed,and Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were applied to distinguish the biological function of the two diseases.Results Compared with control group,102 dysregulated mRNAs and 22 dysregulated lncRNAs showed the same trend in KSD and DCM.And 3 606 mRNAs and 451 lncRNAs were only differentially expressed in KSD group,217 mRNAs and 137 lncRNAs were only differentially expressed in DCM group.The differentially expressed lncRNA/mRNA shared between the KSD and DCM groups were mainly about viral transcription,immuno-inflammatory response,oxidative stress signaling pathways.The KSD specific lncRNA/mRNA mainly participated in cell membrane damage and viral myocarditis.The DCM specific lncRNA/mRNA mainly regulated mitochondrial structure and oxidative phosphorylation related enzymes.Conclusion The differentially expressed lncRNA/mRNA shared in KSD and DCM groups are mainly involved in viral transcription,oxidative stress signaling pathways;KSD specific lncRNA/mRNA are mainly related to cell membrane damage and viral myocarditis;DCM specific lncRNA/mRNA mainly regulate mitochondrial structure.
