ABSTRACT
Objective:To construct a sensitive index system of nursing quality for patients with acute ischemic stroke patients undergoing interventional thrombectomy, so as to provide a scientific basis for interventional thrombectomy care for acute ischemic stroke.Methods:Taking the "structure-process-result" three-dimensional quality model as the theoretical framework, through evidence-based literature search, the item pool was drawn up, and finally the indicators and their weights at each level were determined by two rounds of Delphi method in December 2021 and January 2022 and analytic hierarchy process.Results:The positive coefficients of the two rounds of inquiries to experts were 0.92 and 1.00, respectively, the authority coefficients were 0.913 and 0.917, and the Kendall coefficients were 0.141 and 0.202, respectively. The final index system consisted of 3 primary indicators, 9 secondary indicators and 50 three-level indicators.Conclusions:The nursing sensitive quality index system for patients with acute stroke patients undergoing interventional thrombectomy constructed in this study has high reliability and scientificity, which can provide target incentives for clinical nurses and provide reference for the development of specialized nursing sensitive quality indicators.
ABSTRACT
Non-coding RNA (ncRNA) used to be considered as a class of gene transcripts without protein-coding capacity. Whereas emerging evidence has demonstrated that a small fraction of ncRNAs are still capable of producing functional peptides. Such ncRNAs and corresponding peptides are highly conserved and homologous, and can be detected by sequencing or mass spectrometry analysis. In this paper, we searched several databases with the keywords of "non-coding RNA" and "peptide", and briefly reviewed the characteristics of ncRNA that can be translated into functional small peptides, detection methods of peptides, biological functions of peptides and clinical application value of peptides. The results show that these functional peptides are often involved in disease processes, such as regulation of tumor progression, muscle activity and immune disorders. NcRNA-encoded peptides can be used as novel and efficacious disease diagnostic, therapeutic, and prognostic tools, and further develop as anticancer therapeutic targets to provide new ideas for individual precise treatment of tumors.
ABSTRACT
BACKGROUND: The research focuses of knee osteoarthritis are on mainly articular cartilage, subchondral bone and synovium. There are few studies on the ultrastructure of the meniscus in animal models. OBJECTIVE: On the basis of observing the ultrastructure and types of chondrocytes in the white zone of the meniscus, to observe the ultrastructural changes of the white zone cells of the meniscus in an animal model of early osteoarthritis, in order to explore the relationship between the microstructural changes and the physiological functional changes in the meniscus. METHODS: Sprague-Dawley rats were randomly divided into a control group and a model group. Rats in the model group were made into the model of early knee osteoarthritis by intraarticular injection of papain. After 5 weeks, the meniscuses of three rat models in each group were taken, located and observed for the ultrastructure of the white zone cells through a transmission electron microscope. An ethics approval was obtained from the Animal Ethics Committee of Fujian University of Traditional Chinese Medicine. RESULTS AND CONCLUSION: In the control group, most of cells were fusiform in the superficial layer of meniscus and were triangular-like in the deeper layer. They were rich in rough endoplasmic reticulum and mitochondria, with presence of Golgi and other organelles. Extracellular collagen fibrils were mainly type II collagen fibrils. The cells in the white zone of meniscus were chondrocytes. In the model group, the meniscal surface became rough, the cells were swollen, cytoplasmic organelles were reduced and swollen, glycogen was accumulated, and most of nuclei were abnormal with heterochromatin agglutination. Extracellular collagen fibrils became disordered and sparse. These findings indicate that the mild degeneration of chondrocytes and matrix in the meniscus can reduce the ability of cells to synthesize and secrete matrix components, which may lead to the physiological hypofunction.
ABSTRACT
Objective To analyze the epidemiological characteristics of hepatitis B in Guangzhou from 2006 to 2018. Methods The data were retrieved from the National Infectious Disease Surveillance Information Report Management System. Descriptive methods were used to analyze and summarize the results. Chi-square test was used for statistical analysis of classification data, and Joinpoint software was used to analyze the annual change percentage and trend. Results A total of 292 674 cases of hepatitis B were reported in Guangzhou from 2006 to 2018, and the annual average reported incidence was 182.2 per 100,000. Chronic hepatitis B was the main type, accounting for 89.9%. The incidence rate of males (241.6 / 105) was higher than that of females (117.9 / 105), with a ratio of 2.0:1. During the period from 2006-2018, the reported incidence of hepatitis B in Guangzhou first increased, reached the highest in 2008, and then decreased year by year. There was no significant difference in the number of HBV cases among different months. The average onset age of hepatitis B reported in Guangzhou was 39.3 years old, and the average onset age increased year by year from 2006 to 2018. Conclusion The incidence rate of hepatitis B in Guangzhou has decreased since 2008, but it was still higher than the national average incidence rate. The hepatitis B infection in Guangzhou remains a big issue. It is suggested to further strengthen the prevention and control of hepatitis B in adults by maintaining a national immunization program for children, thereby reducing the epidemiological level of hepatitis B in Guangzhou.
ABSTRACT
Telemedicine technology is a means of deploying medical resources with low cost and high efficiency. A set of remote radiotherapy system based on Citrix was designed in this paper, so that the senior radiation therapists from the developed areas can provide medical services effectively for the patients in the rural areas. This paper focused on the design ideas and the detail of the technical implementation of how to design a remote radiotherapy system based on the existing equipment in the primary hospital. And the technical reliability and security of the remote radiotherapy system were verified by the scientific test method with pairwise comparison. The early practical experience shows that through the remote radiotherapy system the primary radiotherapy personnel and the radiotherapy experts from thirdgrade class-A hospital can form effective alliance in radiotherapy techniques to allow patients in rural areas to receive more professional radiation therapy.

Objective To extract hyperoside from the leaves of Acanthopanax sessiliflorus by complex enzyme method, and optimize the extraction process by orthogonal experiment. Methods Hyperoside was determined by HPLC. Effects of temperature,α-amylase, neutral protease and cellulase on extraction rate were detected by the orthogonal tests, and the optimum extraction condition of hyperoside from the leaves of Acanthopanax sessiliflorus was determined by complex enzyme method. Results The main influence factor was temperature,follows byα-amylase, neutral protease and cellulase according to orthogonal analysis.The best condition was as follows: dose of cellulase, neutral protease and α-amylase was 2%, 0. 5% and 3%, respectively, extract at temperature of 30 ℃for 10 min. Under this condition, the extraction rate of hyperoside in the leaves of Acanthopanax senticosus was 0.52%. Conclusion As compared with the traditional technics, compound enzyme increases the productivity of hyperoside.

This study was aimed to optimize the extraction process of double-marker components for Arctium lappa L. The central composite design and response surface methodology was used. According to 3 main factors, the extraction rates of arctiin and arctigenin was used as evaluation indexes. Multiple linear regression and two-order polynomial equation were used. The binomial fitting model was performed in the optimization of arctiin and arctigenin extraction technology. The results showed that the indentified optimized extraction technology of arctiin and arctigenin was 70% ethanol, 24-fold, ultrasonic solvent extraction for 15 minutes. It was concluded that this technology was able to extract large amount of arctiin and arctigenin, which provided experiment evidences for arctiin and arctigenin preparation. It also provided references for the development and utilization of arctiin and arctigenin.
