Objective:To investigate the effects of rehabilitation nursing based on knowledge-action framework on compliance behavior and coping styles in patients with chronic respiratory failure (CRF), and provide scientific basis and practical guidance for clinical nursing of patients with CRF.Methods:A historical control study was conducted. A retrospective analysis was performed on the clinical data of patients with CRF in Yiwu Central Hospital between January and April 2024. According to admission time, the patients were divided into the control group (admitted from January to February 2024, received routine rehabilitation nursing) and the study group (admitted from March to April 2024, received rehabilitation nursing based on knowledge-action framework). All patients were intervened for 1 month. The differences in self-care ability, compliance behavior, coping styles, quality of life between the two groups were compared using Exercise of Self-Care Agency Scale (ESCA), Compliance Behavior Questionnaire, Trait Coping Style Questionnaire (TCSQ), St. George′s Respiratory Questionnaire (SGRQ).Results:A total of 60 patients with CRF were included, 30 patients in the study group, with 16 males and 14 females, aged (68.72 ± 4.67) years old; 30 patients in the control group, with 17 males and 13 females, aged (69.21 ± 4.18) years old. Before intervention, there were no significant differences in ESCA score, TCSQ score and SGRQ score between the 2 groups (all P>0.05). After 1 month of intervention, ESCA score in the study group was (134.79 ± 5.62) points, higher than (125.34 ± 5.51) points in the control group, the difference was statistically significant ( t=6.58, P<0.05). The compliance behavior (adherence to medical regimens, reasonable diet, work and rest, regular checking) in the study group were 30, 28, 27, 29 cases, higher than 25, 20, 20, 22 cases in the control group, the differences were statistically significant ( χ2 values were 4.81-6.68, all P<0.05). The positive coping score of TCSQ in the study group was (39.67 ± 4.54) points, higher than (32.19 ± 4.38) points in the control group, and score of negative coping score was (13.55 ± 2.28) points, lower than (18.31 ± 2.43) points in the control group, the differences were statistically significant ( t=6.49, 7.82, both P<0.05). The SGRQ score in the study group was (30.23 ± 3.29) points, lower than (35.87 ± 3.66) points in the control group, the difference was statistically significant ( t=6.28, P<0.05). Conclusions:For patients with CRF, rehabilitation nursing based on knowledge-action framework can effectively improve self-care ability and compliance behavior, form more positive coping styles, improve quality of life.

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

The study aims to characterize and compare interferon reference standards from 5 manufacturers. By testing molecular mass and trypsin-digested peptide mass mapping, the amino acid sequence was verified and post-translational modifications such as disulfide bond were identified. Results show that the molecular mass and amino acid sequence were consistent with theory; the disulfide bonds of 4 lots of interferon were Cys1-Cys98/Cys29-Cys138, 1 lot was Cys29-Cys139/Cys86-Cys99; N-terminal "+Met", acetyl N-terminal and Met oxidation were identified in part of the sample. UPLC-MS can be used to characterize and compare interferon reference standards from different manufacturers.

The primary structure of TNK-tissue plasminogen activator (TNK-tPA) was characterized using liquid chromatography-mass spectrometry (LC-MS). Firstly, the molecular mass of deglycosylated protein was measured. Then peptide mass mapping and MS/MS of the reduced, alkylated and trypsin-digested sample were tested and analyzed so as to verify its amino acid sequence and identify post-translational modifications. Results show that the amino acid sequence was consistent with designed structure; about 5% of M207 was oxidized; T61 was fucosylated with -80% occupancy; N103, N448 and N184 (-15% occupancy) were glycosylated with complex-type oligosaccharides. LC-MS coupled with proper sample pretreatment is approved to be a rapid and powerful approach to characterize the primary structure of TNK-tPA.

The amino acid sequence of the fusion protein FP3 was measured by two types of LC-MS/MS and its primary structure was confirmed. After reduction and alkylation, the protein was digested with trypsin and glycosyl groups in glycopeptide were removed by PNGase F. The mixed peptides were separated by LC, then Q-TOF and Ion trap tandem mass spectrometry were used to measure b, y fragment ions of each peptide to analyze the amino acid sequence of fusion protein FP3. Seventy-six percent of full amino acid sequence of the fusion protein FP3 was measured by LC-ESI-Q-TOF with the remaining 24% completed by LC-ESI-Trap. As LC-MS and tandem mass spectrometry are rapid, sensitive, accurate to measure the protein amino acid sequence, they are important approach to structure analysis and identification of recombinant protein.

Structure of a recombinant chimeric anti-CD20 IgG1 monoclonal antibody was verified by the application of high-performance liquid chromatography-mass spectrometry (HPLC-MS)and N-terminal sequencer. Molecular masses, N-terminal sequences and peptide maps of the antibody treated with different reagents and enzymes were measured. Results indicate that the amino acid sequences of light and heavy chains and 10 disulfide bonds were consistent with theoretical structure. By comparison of molecular masses and peptide maps for the fully glycosylated and deglycosylated samples, the N-linked glycosylation site was identified. The method is simple, rapid, precise, and could be referred to the quality control and structure determination of other IgG1 products.

AIM: To observe the curative effect of Jingshichuan Capsule and to try to explore the therapeutic mechanism. METHODS: Medicines were taken orally. During experimental research an animal model of cholelithiasis was established through feeding guinea pig with food which placed a premium on shaping of cholith. The guinea pigs were divided into the pathologic group, the Jingshichuan group and the control group. The animal was executed after sixties days, the gallbladder was taken out by operation to inspect the shaping of cholith; the blood and the bile was collected to be measured; and parts of the tissue of liver and gallbladder were left for pathologic examination. RESULTS: The rate of clinic cure and the rate of effect of Jingshichuan group were separately 40.0% and 96.9%, which was significantly higher than the control group ( P
