Objective To construction and investigate the application effect of auricular acupressure technology in patients with cough with different syndrome types.Methods From December 2022 to March 2023,the Delphi method was used to consult experts to form a technical scheme for auricular pressure in patients with cough with different syndrome types in the early and middle stages.122 patients with stage Ⅰ and stage Ⅱ lung cancer cough from the oncology department of 3 tertiary hospitals of Traditional Chinese Medicine in Beijing between July 2023 to January 2024 were randomly divided into an experimental group(61 cases)and a control group(61 cases).The experimental group referred to the constructed auricular acupressure technique program to identify and take acupoints,and the control group used the original auricular acupressure program for 7 d of continuous intervention.The changes in the scores of the Visual Analog Scale(VAS)and the scores of The MD Anderson Symptom Inventory for lung cancer(MDASI-LC)were observed in the 2 groups before and after the intervention.Results The final scheme included 3 first-level items,12 second-level items,and 14 third-level items.The 2 rounds of expert authority coefficients were 0.88,indicating a high degree of authority,and the Kendall harmony coefficients of the 2 rounds of correspondence were 0.170 and 0.130(P＜0.001),respectively,and the results tended to be consistent.A total of 122 patients completed the study.After intervention,the VAS score of cough severity in the experimental group was 3.0(2.0,3.0)points,which was lower than 3.0(3.0,4.0)points in the control group.The MDASI-LC score of the experimental group was 17.0(9.5,31.5)points,which was lower than 28.0(15.5,47.5)points in the control group,and the difference was statistically significant(P＜0.05).Conclusion The constructed auricular acupressure technique program has certain scientificity,and it can effectively relieve cough symptoms of stage Ⅰ～Ⅱ lung cancer patients,and the severity of symptom clusters has been improved,which provides the basis for TCM nursing intervention in cough symptoms of lung cancer patients.

Objective:To study the method of intravascular angiography in vivo, analyze the clinical significance, and supply the basis of diagnosis and treatment of related orthopaedic diseases.Methods:The development was realized by improving the developer to increase the local concentration. Based on the study of Lijianmin-Chengkun Complexes and using the theory of magnetic microspheres, Fe 3O 4 magnetic microspheres with amino (negatively charged) shell are used to adsorb the aggregated ionic developer meglumine diatrizoate (positively charged diatrizoate). That is, by improving the method of developer, the magnetic microspheres can carry the developer to make new nanoparticles magnetic imaging composite particles. Under the action of external magnetic field, the magnetic imaging composite particles brought by blood circulation continue to stay and gather in the blood vessels in the magnetic field area, and the developer carried by the magnetic microspheres in the blood vessels in the magnetic field area is concentrated to reach the imaging concentration, so as to realize in vivo intravascular vascular imaging. By adjusting the ratio of the two reagents, the charge can be neutralized and condensed into small groups to improve the development efficiency. Thus, the electron microscope experiment, CT in vivo experiment, rabbit imaging experiment, experimental rabbit tissue picture confirmation, CT in vivo human body (the author is a volunteer) imaging experiment were carried out step by step. Results:Electron microscope experiment: meglumine diatrizoate, scanning electron microscope, the particle diameter is about 20 nm. Scanning electron microscope showed that the diameter of the magnetic microspheres was about 100 nm and the distribution was uniform. After the two reagents are mixed in a certain proportion, the neutralizing charge condenses into small groups, but it still has magnetohydrodynamic properties and strong paramagnetism. In vivo rabbit imaging experiment: the ideal intraosseous vascular imaging of the proximal tibia was captured. The tissue pictures of experimental rabbits confirmed that the distribution of Fe 3O 4 was obviously visible in the blood vessels in the proximal tibia on the side with magnetic field, but not on the side without magnetic field. In vivo human imaging experiment: the ideal intraosseous vascular imaging of the proximal fibula was captured. Conclusion:Through the preparation of new reagent of magnetic imaging composite particles (magnetic microspheres + meglumine diatrizoate), the concentration of in vivo bone developer can be achieved under the action of external magnetic field, and the in vivo external diameter ≥ 0.5mm can be achieved under CT thin-layer scanning.

Objective To conduct the molecular epidemiologic analysis of Staphylococcus aureus (S.aureus) in the intensive care units(ICUs) and general wards and to compare their clinical characteristics.Methods Ninety-six clinically isolated strains of S.aureus(43 strains from the emergency intensive care unit(EICU) and neurosurgical intensive care unit(NICU) and 53 strains from the general wards) collected from Sepetember 2015 to April 2016 were performed the bacterial identification and antibiotic susceptibility test.The molecular typing was performed by adopting staphylococcal protein A (spa) typing method.Results Among 96 strains of S.aureus,the detection rate of methicillin-resistant S.aureus(MRSA) was 40.6%(39/96),which among 43 strains in ICU was 62.8%(27/43) and which among 53 strains in the general words was 22.6%(12/53).The resistance rates of strains from ICUs to gentamicin,levofloxacin,clindamycin,fosfomycin and minocycline were 23.3%,48.8%,46.5%,32.6% and 32.5% respectively,while which from the general wards were 7.5%,24.5%,18.9%,2.1% and 0% respectively.The Spa typing results showed that the main types of ICUs were t002,t091 and t311.The major epidemic strain was t002(n=16,37.2%) and mainly isolated from EICUs(12 strains),26 spa types were identified among the general wards trains,mainly were t189,t377,t571,t034,t091,t127.Conclusion The detection rate of MRSA in ICUs is higher than that in the general wards,these strains have high resistant rate to routine antibacterial drugs.t002 is the major epidemic strain.The general wards have more spa types with higher genetic diversity.
