OBJECTIVE To optimize the heart-nourishing granule extraction process by network pharmacology and Box-Behnken response surface method. METHODS The active ingredients of heart-nourishing granule were excavated through network pharmacology and their mechanism of action in the treatment of coronary heart disease was preliminarily explored. Molecular docking technology was used to predict the binding ability of the active ingredients to the main targets. At the same time, based on the compatibility relationship between the monarch, minister, assistant and guide of the prescription, the pharmacological effects of the ingredients, and the content determination index components of each medicinal flavor in the 2020 edition of the Chinese Pharmacopoeia, the process evaluation index components of heart-nourishing granule were further determined. In addition, combined with the analytic hierarchy process to determine the weight of each component, the Box-Behnken response surface method was used to optimize the extraction process of heart-nourishing granule. RESULTS The main active components of heart-nourishing granule screened were catalpol, Rhmannioside D, acteoside, ferulic acid and lobetyolin. By acting on core targets such as AKT1, IL-6, IL-1b, VEGFA, JUN and MAPK3, they regulated lipid and atherosclerosis, MAPK signaling and other pathways played a role in the treatment of coronary heart disease. Molecular docking results showed that the binding energies of active components and core targets predicted by network pharmacology were all < -5.0 kJ·mol-1. Five components catalpol, Rhmannioside D, acteoside, ferulic acid and lobetyolin were calculated by analytic hierarchy process method. The weight coefficients of arginyl glycosides were 0.329 7, 0.329 7, 0.164 8, 0.109 9, and 0.065 9, respectively. The Box-Behnken response surface method obtained the optimal water extraction process: 10 times the amount of water was used to extract twice, and each time was decocted for 1.5 h. The verification test showed that the contents of the five components were consistent with the predicted values, and the RSD values were all <5%. CONCLUSION The extraction process of heart-nourishing granule based on network pharmacology and Box-Behnken response surface methodology is stable and feasible, which provided an experimental basis for its further quality improvement.

Objective:To apply the best evidence of non-drug management of chemotherapy induced nausea and vomiting (CINV) in clinical practice, and evaluate the effect of practice.Methods:After searching domestic and foreign databases, 14 articles were finally included, including 3 systematic reviews, 3 evidence summaries and 8 guidelines. According to the evidence-based continuous quality improvement model of Joanna Briggs Institute (JBI) Evidence-based Nursing and Health Care Center, we conducted the review before and after evidence application, obstacle factors, available resources and strategy analysis, and evaluation of the effect of evidence application. From March to May 2020, convenience sampling was used to select 52 inpatients with gynecological chemotherapy in the Affiliated Hospital of Qingdao University and 26 clinical nurses as subjects for baseline review. From June to August 2020, 42 inpatients with gynecological chemotherapy and 26 clinical nurses (same as before) were selected for re-review.Results:The management process, nursing routine, nursing path, and risk assessment and follow-up form for CINV were improved, and an evidence-based education video was produced. After application of the evidence, the compliance of nurses' review indicators improved, and the differences were statistically significant ( P<0.05) . The scores of nurses on the non-drug management evidence-based knowledge questionnaire for gynecological CINV increased, and the difference was statistically significant ( P<0.05) . The incidence of acute CINV decreased, and the difference was statistically significant ( P<0.05) . The incidence of delayed CINV decreased, and the difference was not statistically significant ( P> 0.05) . Conclusions:The development of the evidence-based practice project promotes the improvement of related processes, routines, and paths, enriches the forms and content of CINV non-drug antiemetic education, standardized nurses' behavior, improves nurses' compliance with evidence-based practice, and reduces the incidence of acute nausea and vomiting in patients.

Objective:To analyze the malignant probability of thyroid nodules with the diagnosis of atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) determined by fine-needle aspiration (FNA) and to explore the value of the combined application of BRAFV600E gene detection for the diagnosis of benign and malignant thyroid nodules. Methods:A total of 114 patients including 20 males and 94 females, aged 16-76 years old with thyroid nodules underwent FNA examination and surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2018 to November 2019 were retrospectively analyzed. Postoperative histopathological results were used as the gold standard for the diagnosis of malignant thyroid nodules. The malignant rate of thyroid nodules with the diagnosis of AUS/FLUS was evaluated. Differential diagnostic efficacy of preoperative FNA combined with BRAFV600E gene detection for papillary thyroid carcinoma (PTC) was analyzed by McNemer test and diagnostic test evaluation method. Results:The mutation rate of BRAFV600E gene was 84.76% (89/105) in PTC. PTC accounted for 57.14% (12/21) of the patients with the diagnoses of AUS/FLUS determined by FNA. The specificity, sensitivity, positive predictive value and negative predictive value of BRAFV600E mutation examination for the diagnosis of malignant thyroid nodules determined preoperatively as AUS/FLUS were 9/9, 5/12, 5/5 and 9/16, respectively. BRAFV600E mutation examination could improve the detection rate of PTC in patients with AUS/FLUS ( OR=0.438, 95% CI=0.251-0.763, P=0.016). Conclusion:FNA combined with BRAFV600E mutation examination can significantly improve the detection rate of malignant thyroid nodules diagnosed preoperatively as AUS/FLUS.

BACKGROUND: Nowadays, fish collagen biomedical materials still exhibit obvious deficiency in thermal stability,in vivo degradation stability and in vivo material morphology stability. To expand the application of fish source collagen, it is urgent to improve the material performance by increasing the density and collagen molecule tightness of freshwater fish collagen sponge materials using technique methods.OBJECTIVE: To optimize the reconstitute process for nasopore preparation using fish scale collagen.METHODS: The optimal process for nasopore preparation through the reconstitution of fish scale collagen was ascertained by taking tilapia fish skin as a raw material to extract enzymatic soluble collagen at a temperature lower than the collagen denaturation temperature and recombinant rate of collagen fibers as index. Optimization of the conditions for nasopore preparation was carried out using single factor test and orthogonal test. The prepared nasopore was analyzed through infrared spectroscopy and microstructure analysis.RESULTS AND CONCLUSION: The optimal conditions for nasopore preparation were determined through the single factor test and orthogonal test as follows: 20 ℃ for 10 hours at pH 7.4 using a mixture of 65 mmol/L NaCl and 1 g/L collagen, by which the reconstitute rate of collagen fibers was up to 68.6%. The prepared nasopore is characterized by a refined porous structure constituted by threadlike collagen fibers, and has complete three-dimensional spiral structure,which is a potential intracavitary hemostatic material with fine properties.

OBJECTIVETo analyze the proportion and associated factors of taking subsequent confirmation test among men who have sex with men (MSM) after being tested positive in oral fluid HIV antibody test.

METHODSBy using successive sampling, 1 003 MSM, who were tested positive in oral fluid HIV antibody test in China-Bill & Melinda Gates Foundation AIDS prevention Program (Extension program) in Beijing during May 1 to December 31, 2013, were recruited. The inclusion criteria included: the objects were men who reported having sex with men; the objects aged more than 18 years old; the objects were tested positive in oral fluid HIV antibody test; the objects had not been reported as HIV positives in China Information System for Disease Control and Prevention previously. According to the program strategy, MSM grassroots organizations transferred the respondents to seek subsequent confirmation tests in specific Center for Disease Control and Prevention (CDCs) or hospitals. The subsequent confirmation tests included: fingertip blood HIV antibody rapid test, venous blood Enzyme Linked Immunosorbent Assay (ELISA) HIV antibody test and venous blood Western Blot (WB) HIV antibody test. Chi-square test was adopted to compare the proportion of taking subsequent confirmation tests in different groups. Nonconditional multivaritae binarylogistic regression analysis was taken to identify the associated factors with whether taking subsequent confirmation tests and to calculate the OR (95% CI) values.

RESULTSThe 1 003 respondents were (30.9 ± 9.1) years old. Among all objects, 87.8% (881/1 003) of them took fingertip blood HIV antibody rapid tests and the positive rate was 85.4% (752/881). 98.0% (737/752) of those who were identified as positive in fingertip blood HIV rapid tests took ELISA and WB tests, and the positive rate was 94.4% (696/737). Comparing with those who were expected to seek subsequent confirmation tests in CDCs, the OR (95% CI) value of those who were expected to seek tests in hospitals was 5.10 (1.69-15.36). The OR (95% CI) values of those who used condom sometimes and those who never used condom in anal sex were 5.81 (2.14-15.77) and 3.45 (2.00-5.97) respectively, in comparison with those who reported not having anal sex or using condom consistently in anal sex during the past 6 months. Comparing with the respondents recruited from the internet, the OR (95% CI) values of those recruited in bathrooms, parks/toilets and bars were 0.17 (0.05-0.53), 0.10 (0.04-0.29) and 0.22 (0.06-0.79) respectively. The likelihood of taking subsequent confirmation test decreased with the increase of number of male sexual partners in the past 3 months, and the OR (95% CI) value was 0.92 (0.86-0.99).

CONCLUSIONThe potential HIV positive MSM in the bathroom, park/toilet and bars are less likely to take subsequent confirmation test. Those who do not use condom consistently during anal sex are more likely to seek subsequent confirmation test. Medical organization conducting subsequent confirmation tests is more likely to increase the confirmation test rate of potential HIV positive MSM. The number of male sexual partners has negative correlation with whether to accept the subsequent confirmation test.

Objective To study the feasibility of high performance liquid chromatography-evaporative light scattering detector ( HPLC-ELSD) in quantitative analysis of multi-components ( QAMS) by single marker. Methods Four saponins in Astragali Radix were simultaneously determined by HPLC-ELSD using external standard method, and malonylastragaloside I served as internal standard. The relative correction factors between internal standard and astragaloside Ⅰ, astragaloside Ⅱ and astragaloside Ⅳ were calculated, and the stability was investigated. Results Astragaloside Ⅳ in Astragali Radix was little, while malonylastragalosideⅠand AstragalosideⅠwere abundant.The relative correction factors lacked stability, so ELSD could not be used in QAMS. Conclusion HPLC-ELSD can precisely determine contents of four saponins in Astragali Radix. The detector needs to be further studied when the components have poor ultraviolet absorption such as saponins by QAMS.

Objective To explore the effects of nurse-physician collaboration model on anxiety, depression and quality of life (QOL)of patients undergoing concurrent chemo-radiotherapy.Methods A total of 1 80 eligible patients from December 201 3 to December 201 4 were randomly divided into study group (n =96) and control group (n =84).The patients of study group received nurse-physician collaboration nursing,while the patients of control group received routine nursing.The self-rating anxiety scale (SAS ),self-rating depression scale (SDS ) and European organization for research and treatment of cancer quality of life questionnaire-3.0 (EORTC QLQ-C30)were used to investigate the differences between groups before and after intervention.Results Anxiety and depression in study group were better than those in control group after treatment,and the difference was statistically significant (P <0.05).Overall health,emotional function,social function,cognitive function,role function,pain,insomnia and breathing difficulties were better in study group than those in control group after treatment (P <0.05).Conclusions Nurse-physician collaboration model can improve the anxiety,depression and QOL of patients receiving chemoradiotherapy.

Objective To explore the change of monocyte chemotactic factor-1 protein(MCP-1)and matrix metalloproteinase-9( MMP-9)of patients with coronary artery disease( CAD)following percutaneous coronary interventional( PCI). Methods Fifty patients underwent PCI procedures for CAD compromising a single coronary artery were selected as PCI group and 30 healthy individuals with normal findings by coronary angiography were selected as the control group. Plasma MCP-1 and MMP-9 were measured in all the subjects. Results The plasma MCP-1 level of patients with CAD after PCI was(19. 87 ± 5. 31)ng/ L,higher than that before operation((15. 71 ± 5. 23)ng/ L,t = 3. 95,P < 0. 01). Whereas in the control group,the MCP-1 level after coronary angiography was(13. 78 ± 5. 58)ng/ L,which was as same as that before operation (12. 42 ± 5. 39 ng/ L,P = 0. 34). Plasma MMP-9 level in the CAD patients after PCI procedures was(22. 69 ± 5. 97)mg/ L,higher than that before operation((19. 52 ± 5. 72)mg/ L,t = 2. 71,P < 0. 01). There was no significant difference in term of plasma MMP-9 level in control group befor and after operation((17. 53 ± 5. 51) mg/ L vs.(16. 69 ± 5. 42)mg/ L,P = 0. 55). Conclusion Plasma MCP-1 and MMP-9 increase in CAD patients following PCI procedures. But their roles in the vascular restenosis following the procedures need further investigation.
