Objective:To review the clinical status based on the best evidence of drug administration in patients with dysphagia, systematically analyze the obstacle factors and promoting factors in the process of evidence transformation, and formulate reform strategies.Methods:Based on the evidence-based nursing research method and the guidance of the Ottawa Model of Research Use (OMRU), the review indicators were developed based on the best evidence. The current status of clinical practice behaviors of 223 patients and 75 nurses in the Neurology, Neurosurgery and Geriatric departments of the Affiliated Hospital of Jiangsu University were reviewed from July to December 2021.Based on the results of the review, qualitative interviews were conducted with 32 potential adopters, and content analysis was used to assess the barriers and contributing factors to the clinical translation of evidence in three aspects: evidence-based change, potential adopters and practice environment, so as to develop effective strategies.Results:Based on the 22 best evidence selected, the evidence-based team developed 25 review indicators to carry out clinical review, showing that the compliance rate of 16 indicators were less than 60%. By analyzing and summarizing the interview results of potential adopters, the main obstacles leading to the low compliance rate of nurses were analyzed as follows: evidence-based reform changed the traditional work mode, and the application of evidence was not convenient; at the level of potential adopters, nurses had poor knowledge and practice, heavy work burden, and low awareness of patients and caregivers; at the level of practice environment, there was lack of nursing norms and procedures for clinical transformation of evidence, and the channels of multi-disciplinary collaboration and communication were not smooth. The main promoting factors were the perfect supervision mechanism of evidence-based nursing projects, the evidence-based group had rich experience in evidence transformation, the management was willing to change, and the practitioners were good at innovation.Conclusions:There is still a large gap between the clinical practice and the best evidence of drug administration in patients with dysphagia. The promoting factors should be fully utilized to overcome the obstacles and implement improvements to promote the effective transformation of evidence into clinical practice.

Objective:To carry out an overview of systematic reviews on interventions to prevent the recurrence of diabetic foot ulcer (DFU) patients.Methods:Systematic reviews or Meta-analysis on interventions to prevent DFU recurrence were electronically retrieved from databases such as China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc, Joanna Briggs Institute (JBI) Evidence-Based Healthcare Center Database, Cochrane Library, PubMed, Embase, CINAHL and Web of Science. The search period was from database establishment to April 20, 2023. Two researchers independently searched and screened literature, and extracted data, and used AMSTAR 2 software and the quality evaluation criteria for systematic review of JBI Evidence-Based Healthcare Center to evaluate the methodological quality of the included literature. GRADE evaluation system was used for quality assessment of outcome indicators (DFU recurrence rate, effectiveness of measures to prevent DFU recurrence) .Results:A total of 24 systematic reviews were included. Studies showed that monitoring and intervention of foot skin temperature, therapeutic shoes or insoles, comprehensive intervention measures, and specific surgical methods could reduce the recurrence rate of DFU, while foot self-care, foot exercise, health education, and psychological intervention had no statistical effect on preventing DFU recurrence. The methodological quality of systematic reviews was generally low. The reports of four articles were relatively complete, 18 articles had certain defects, and two articles had serious defects. The evaluation of evidence quality showed that there were three pieces of moderate-quality evidence, seven pieces of low-quality evidence, and 30 pieces of extremely low-quality evidence.Conclusions:Existing evidence suggests that foot skin temperature monitoring and intervention, therapeutic shoes or insoles, comprehensive intervention measures, and specific surgical methods (such as Achilles tendon lengthening, metatarsophalangeal joint replacement, metatarsal head resection and so on) have a positive impact on preventing DFU recurrence. Rigorous and high standard research is still needed to verify the controversial issues, so as to provide reliable evidence for future clinical practice and studies.

Farnesyl diphosphate synthase(FPPS) is a key enzyme at the branch point of the sesquiterpene biosynthetic pathway, but there are no reports on the transcriptional regulation of FPPS promoter in Pogostemon cabin. In the early stage of this study, we obtained the binding protein PcFBA-1 of FPPS gene promoter in P. cabin. In order to explore the possible mechanism of PcFBA-1 involved in the regulation of patchouli alcohol biosynthesis, this study performed PCR-based cloning and sequencing analysis of PcFBA-1, analyzed the expression patterns of PcFBA-1 in different tissues by fluorescence quantitative PCR and its subcellular localization using the protoplast transformation system, detected the binding of PcFBA-1 protein to the FPPS promoter in vitro with the yeast one-hybrid system, and verified its transcriptional regulatory function by dual-luciferase reporter gene assay. The findings demonstrated that the cloned PcFBA-1 had an open reading frame(ORF) of 1 131 bp, encoding a protein of 376 amino acids, containing two conserved domains named F-box-like superfamily and FBA-1 superfamily, and belonging to the F-box family. Moreover, neither signal peptide nor transmembrane domain was contained, implying that it was an unstable hydrophilic protein. In addition, as revealed by fluorescence quantitative PCR results, PcFBA-1 had the highest expression in leaves, and there was no significant difference in expression in roots or stems. PcFBA-1 protein was proved mainly located in the cytoplasm. Furthermore, yeast one-hybrid screening and dual-luciferase reporter gene assay showed that PcFBA-1 was able to bind to FPPS promoter both in vitro and in vivo to enhance the activity of FPPS promoter. In summary, this study identifies a new transcription factor PcFBA-1 in P. cabin, which directly binds to the FPPS gene promoter to enhance the promoter activity. This had laid a foundation for the biosynthesis of patchouli alcohol and other active ingre-dients and provided a basis for metabolic engineering and genetic improvement of P. cabin.

Complex coronary heart disease (CHD) has become a hot spot in medicine due to its complex coronary anatomy, variable clinical factors, difficult hemodynamic reconstruction, and limited effect of conservative drug treatment. Identifying complex CHD and selecting optimal treatment methods have become more scientific as revascularization technology has improved, and coronary risk stratification scores have been introduced. SYNTAX and its derivative scores are decision-making tools that quantitatively describe the characteristics of coronary lesions in patients based on their complexity and severity. The SYNTAX and its derivative scores could assist clinicians in rationalizing the selection of hemodynamic reconstruction treatment strategies, and have demon-strated outstanding value in evaluating the prognosis of patients with complex CHD undergoing revascularization treatment. The authors in this article summary the practical application of SYNTAX and its derivative scores in complex CHD in order to deepen the understanding of the relationship between the choice of different revascularization strategies and SYNTAX and its derived scores in complex CHD and provide a further reference for clinical treatment of complex CHD.

Medical staff should pay attention to these influencing factors and take corresponding measures for targeted prevention, so as to improve the quality of diabetic foot care services.

OBJECTIVE: To investigate the types and laboratory characteristics of non-Hodgkin lymphoma(NHL) with bone marrow invasion as the first manifestation. METHODS: 81 non-Hodgkin lymphoma patients with bone marrow invasion as the first manifestation treated in our hospital from January 2010 to July 2019 were selected. The clinical features, blood routine, lactate dehydrogenase (LDH), EB virus results, bone marrow features, immunophenotyping, gene and genetic characteristics of all patients were analyzed retrospectivel. RESULTS: Among 81 patients, 73 cases(90%) were B-cell lymphoma, 5 cases(6%) were T-cell lymphoma and 3 cases(4%) were NK/T-cell lymphoma, while the mantle cell lymphoma and diffuse large B-cell lymphoma were the highest, which accounted for 21%(17 cases) and 19.7%(16 cases), and lymphoma accounted for 8.6%(7 cases). There were 44 cases(54.3%) showed B symptoms, 65 cases (80.2%) showed abnormal blood routine. The MYD88 gene was detected in 5 of 17 cases. 25 cases of patients underwent chromosome examination, the result showed that 5 cases were t(8; 14) (q24; q32), 3 cases were complex karyotype and 17 cases were normal karyotype. 23 cases(23.4%) were EB virus positive, 42 cases(51.9%) were LDH increased. The proportion of bone marrow lymphoma cells was 1%-92%. Among them, 32 cases were diagnosed as lymphoma leukemia, and 6 cases of bone marrow lymphoma cells showed mass distribution similar to extramedullary tumor cells with bone marrow metastasis. CONCLUSION B-cell lymphoma is the predominant NHL with bone marrow invasion as the first manifestation, while mantle cell lymphoma and diffuse large B-cell lymphoma are the most common pathological types with blood routine abnormalities. Bone marrow lymphoma cells can also present clusters of bone marrow metastasis, different types of lymphoma cells can make directional diagnosis.

Objective:To explore the application effect of target management model based on standardized Metabolic Management Center (MMC) in newly diagnosed diabetic patients.Methods:A total of 80 inpatients who were newly diagnosed as diabetes mellitus in Department of Endocrinology and Metabolism in Affiliated Hospital of Jiangsu University from October 2018 to March 2019 were selected as the convenient sampling method. According to the random number table method, they were divided into the observation group and the control group, with 40 cases in each group. The control group was given routine nursing management while the observation group was given target management by using supporting facilities of MMC based on the control group. The changes of fasting plasma glucose (FPG) , 2 h postprandial blood glucose (2hPG) , glycated hemoglobin (HbA1c) , body mass index (BMI) and self-management behavior scores before and after 6 months of intervention were compared between the two groups.Results:There were no statistically significant differences in blood glucose index, BMI and self-management behavior score between the two groups before the intervention ( P>0.05) . After intervention, the blood glucose and self-management behavior scores of the observation group were better than those of the control group, and the differences were statistically significant ( P<0.05) . The BMI of observation group after intervention was lower than that before intervention, and the difference was statistically significant ( P <0.05) . There was no statistically significant difference before and after intervention in the control group ( P>0.05) . Conclusions:Target management based on the MMC is conducive to improving the self-management ability of newly diagnosed diabetic patients and helps them to effectively control blood glucose and body weight.

OBJECTIVE: To noninvasively assess the neurodegenerative changes in the brain of patients with Niemann-Pick type C (NPC) disease by measuring the lesion tissue with the iterative decomposition of water and fat with echo asymmetry and least square estimation-iron quantification (IDEAL-IQ). MATERIALS AND METHODS: Routine brain MRI, IDEAL-IQ and 1H-proton magnetic resonance spectroscopy (1H-MRS, served as control) were performed on 12 patients with type C Niemann-Pick disease (4 males and 8 females; age range, 15–61 years; mean age, 36 years) and 20 healthy subjects (10 males and 10 females; age range, 20–65 years; mean age, 38 years). The regions with lesion and the normal appearing regions (NARs) of patients were measured and analyzed based on the fat/water signal intensity on IDEAL-IQ and the lipid peak on 1H-MRS. RESULTS: Niemann-Pick type C patients showed a higher fat/water signal intensity ratio with IDEAL-IQ on T2 hyperintensity lesions and NARs (3.7–4.9%, p < 0.05 and 1.8–3.0%, p < 0.05, respectively), as compared to healthy controls (HCs) (1.2–2.3%). After treatment, the fat/water signal intensity ratio decreased (2.2–3.4%), but remained higher than in the HCs (p < 0.05). The results of the 1H-MRS measurements showed increased lipid peaks in the same lesion regions, and the micro-lipid storage disorder of NARs in NPC patients was detectable by IDEAL-IQ instead of 1H-MRS. CONCLUSION: The findings of this study suggested that IDEAL-IQ may be useful as a noninvasive and objective method in the evaluation of patients with NPC; additionally, IDEAL-IQ can be used to quantitatively measure the brain parenchymal adipose content and monitor patient follow-up after treatment of NPC.
