OBJECTIVE To explore the action mechanism of kushenol F (KSCF) in treating ulcerative colitis (UC) in mice. METHODS The potential targets of KSCF intervening in UC were predicted with network pharmacology and molecular docking. C57BL/6J mice were randomly divided by body weight into model group, positive control group (sulfasalazine, 703 mg/kg), KSCF group (100 mg/kg), and normal group, with 6 mice per group. The UC model of mice was induced by dextran sulfate sodium solution. During the modeling period, the mice were given relevant medicine intragastrically, once a day, for 7 consecutive days. After the last administration, the disease activity index (DAI) of the mice was scored; the length of the mice’s colon was measured; pathological changes in the colon tissue of mice were observed; the levels of lipopolysaccharide (LPS) in serum, myeloperoxidase (MPO), nitric oxide (NO) and superoxide dismutase (SOD) in the colon were detected in mice; the expression levels of occludin and ZO-1 in colon tissue of mice were detected; the proportions of CD3+T, CD4+T, and CD8+T lymphocytes in the spleen and the ratio of CD4+/CD8+ were detected; changes in colonic microbiota were analyzed by 16S rDNA sequencing. RESULTS Results of network pharmacology indicated that KSCF may treat UC by regulating signaling pathways such as phosphatidylinositol-3 kinase/protein kinase B (PI3K/AKT) and nuclear factor kappa B (NF- κB). Molecular docking results showed that KSCF bound most stably with NF-κB p65 protein. Animal experiment results demonstrated that, compared with the model group, the pathological characteristics of colon tissue in mice were improved in KSCF group. DAI scores, serum levels of LPS, the levels of MPO,NF-κB p65 phosphorylation and NLRP3 protein expression in the colon, and the proportion of CD8+T lymphocytes in the spleen were reduced significantly (P<0.05). Body weight, SOD levels, expression levels of occludin and ZO-1 in the colon, proportions of CD3+T and CD4+T lymphocytes, and the CD4+/CD8+ ratio in the spleen were significantly increased (P<0.05); the abundance of Firmicutes, Actinobacteria, Akkermansia, and Lactobacillus genera were increased, while Proteobacteria decreased; the microbial community structure tended towards that of the normal group. CONCLUSIONS KSCF alleviates UC by restoring intestinal microbial imbalance, enhancing immune response, and inhibiting colonic inflammatory responses, thereby improving intestinal barrier integrity.

Objective:To investigate the facilitators and hindrances of smoking cessation in patients with chronic obstructive pulmonary disease (COPD), and to provide a basis for developing individualized smoking cessation intervention strategies for COPD patients.Methods:Based on the health ecology theory and using a phenomenological approach in qualitative research, purposive sampling was used to select 15 COPD patients with smoking history who were admitted to Tianjin Fourth Central Hospital from March to May 2023 and face-to-face semi-structured interviews were conducted. Colaizzi seven-step analysis was used to analyze the interview content.Results:A total of 15 COPD patients were interviewed, including 13 males and 2 females, aged 61-75 years old. The facilitators of smoking cessation in COPD patients included complications, sequelae of novel coronavirus infection, fear of death, smoking cessation counseling by medical staff, heavy family financial burden, and smoke-free environment. The hindrances of smoking cessation in COPD patients included milder disease symptoms of COPD, higher levels of nicotine dependence, false disease-related perceptions, family supervision and control, and occupational experience.Conclusions:Smoking cessation in COPD patients is influenced by five factors: personal characteristics, behavioral characteristics, interpersonal network, living and working conditions, and policy environment. Medical staff and relevant national institutions should formulate corresponding smoking cessation strategies according to address the facilitators and hindrances of smoking cessation in COPD patients, so as to further reduce the smoking prevalence of COPD patients, promote the health of patients and reduce the burden of disease.

Objective:
To explore the role and mechanism of long noncoding RNA(lncRNA) AC005062.1 in colorectal cancer(CRC) cell proliferation and apoptosis.
Methods:
The analysis of GSE84983 and GSE 104364 was used to indicate the expression level lncRNA AC005062.1 in CRC. The tumor tissues(tumor group) and adjacent tissues(control group) of patients undergoing CRC surgery in the hospital tumor surgery department were collected. Eight pairs of tissues were randomly selected, and qPCR was used to detect the expression of lncRNA AC005062.1 in CRC tissues and paired adjacent tissues in the two groups. After using siRNA to down-regulate the expression of lncRNA AC005062.1 in CRC cells, CCK-8 assay was used to detect cell proliferation in two groups, flow cytometry was used to detect cell cycle and apoptosis in two groups, wound scratch test was used to detect cell migration in two groups, and the lncRNA was determined. The database was used to compare the localization of lncRNA AC005062.1 and MACC1 genes on staining. The expression levels of MACC1 transcription and protein levels in the control group and tumor group were detected by qPCR and Western blot, respectively. The lncRNA AC005062.1 in CRC cells was down-regulated, and the expression levels of MACC1 transcription and protein levels in the two groups of cells were detected by qPCR and Western blot, respectively.
Results:
The database analysis of GSE84983 and GSE104364 and the detection results of the two groups indicated that the lncRNA AC005062.1 was highly expressed in CRC. After down-regulation of lncRNA AC005062.1, the results of CCK-8 experiments showed that the proliferation rate of HT29 cells in the down-regulation group decreased. Flow cytometry showed that the number of apoptosis of HT29 cells in the down-regulated group increased, the proportion of G1 phase increased, and the proportion of S phase and G2 phase decreased. Western blot experiments showed that the expressions of cleaved-caspase3 and Bax in the down-regulated HT29 cells increased, while the expression of Bcl-2 decreased. Wound scratch experiments showed that the migration rate of HT29 cells in the down-regulated group was lower than that in the control group. The analysis of UCSC to compare the location of lncRNA ac005062.1 and MACC1 on chromosomes showed that they were located very close together. MACC1 was highly expressed in CRC and down-regulated lncRNA AC005062.1 expression in HT29 cells could reduce the expression of MACC1.
Conclusion
lncRNA AC005062.1 can inhibit the proliferation, cycle and migration of HT29 cells, and promote its apoptosis by regulating the expression of MACC1 in CRC.

Objective:To investigate the image characteristics of woven coronary artery (WCA)on intravascular ultrasound(IVUS) and optical coherence tomography(OCT).Methods:Thirty-seven patients suspected of WCA on coronary angiography were enrolled from Teaching Hospital of Chengdu University of Traditional Chinese Medcine, Zhengzhou Cardiovascular Disease Hospital and Zhongshan Hospital of Fudan University from January 2013 to July 2020. The intraluminal imaging features of WCA were analyzed using IVUS and OCT.Results:Of the 37 patients admitted at the cardiology service, 9 patients had WCA. All the patients underwent coronary angiography, IVUS and OCT, of which 6 lesions were located on the right coronary artery, 2 lesions were located on the left anterior descending artery and 1 patient had WCA on the circumflex artery. The mean length of WCA lesions was 2.2 cm(ranged from 1.2 cm to 4.5 cm). The angiographic appearance of WCA was numerous small tortious channels origined form the main lumen. The channels appeared to be " doughnut" like pattern and they merged to normal artery again after the anomalous segment. Flow limitation was rare unless there was coronary atherosclerosis. OCT and IVUS showed multiple spiral channels in the anomalous segment, which were independent of each other and each channels had a relatively complete three-layers vascular structure.Conclusions:With typical image characteristics, IVUS and OCT are able to screen out WCA and guide the treatment decision making.

Objective To investigate the safety and effectiveness of endovascular treatment and surgical clipping for the treatment of intracranial ruptured aneurysms. Methods From January 2012 to December 2017, patients with ruptured intracranial aneurysm treated at the Department of Neurosurgery, the Second People's Hospital of Taizhou were enrolled retrospectively. The demographics, baseline clinical data,outcomes, and complications were compared between the endovascular treatment group and the surgical clip group. Results A total of 220 patients were enrolled, they aged 55. 1 ±11. 8 years. There were 117 patients in the endovascular treatment group and 103 in the surgical clipping group. There were no significant differences in perioperative complications (26. 2% vs. 19. 6%; χ2 = 1. 340, P = 0. 247), in-hospital mortality (6. 0%vs. 4. 9%; χ2 = 0. 135, P = 0. 713), and good outcomes at discharge (85. 5% vs. 81. 6%; χ2 =0. 614, P = 0. 433) between the two groups. Multivariate logistic regression analysis showed that age (odds ratio [OR] 1. 072, 95% confidence interval [CI] 1. 025-1. 124; P < 0. 001), smoking (OR 6. 325, 95% CI 2. 367-16. 901; P < 0. 001 ), and high World Federation of Neurosurgery Societies (WFNS) grade (OR 5. 218, 95% CI 1. 881-14. 449; P < 0. 001) had significant independent correlation with the poor clinical outcome at discharge. The imaging follow-up data in 155 aneurysms (81 in the endovascular treatment group and 74 in the surgical clipping group) were available. The follow-up time was 14. 3 ± 6. 9 months (range, 6-36 months); 20 aneurysms (12. 9%) had recurrence. There was no significant difference in the recurrence rate of the endovascular treatment group and surgical clipping group (17. 3% vs. 8. 1%; χ2 =2. 900, P = 0. 089). The clinical follow-up data of 188 patients (95 in the endovascular treatment group and 93 in the surgical clipping group) were available. The follow-up time was 15. 5 ± 6. 8 months (range, 6- 36 months). There was no significant difference in the good outcome rate between the endovascular treatment group and surgical clipping group (95. 8% vs. 90. 3%; χ2 = 2. 182, P = 0. 140 ). Multivariate logistic analysis showed that smoking (OR 4. 872, 95% CI 1. 719-13. 872; P < 0. 001 ) and high WFNS grade (OR 3. 512, 95% CI 1. 446-8. 583; P < 0. 001) were the independent risk factor for long-term poor outcome. Conclusion The efficacy and safety of surgical clipping for ruptured intracranial aneurysms were comparable to endovascular treatment. Age, smoking, and WFNS grade were the important factors affecting the outcomes of patients.

Objective? To explore the effects of humanized nursing service in ophthalmology ward. Methods? Between May 2016 to February 2018, a total of 200 patients in the ophthalmology ward of Shaoxing People's Hospital of Zhejiang Province were selected as the research subjects by convenience sampling method. According to the sequence of admission, the subjects were divided into control group and intervention group, with 100 cases in each group. The patients in both groups received routine ophthalmic care. The intervention group received humanistic nursing service at the same time. The scores of Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), patient satisfaction, nursing complaints and disputes were compared between the two groups. Results? Before the intervention, there were no statistical differences in the scores of SAS and SDS between the two groups (P>0.05). After the intervention, the scores of SAS and SDS in the intervention group were both lower than those in the control group, and the differences were statistically significant (P< 0.05). The satisfaction rate of the intervention group was higher than that of the control group, and the difference was statistically significant (P<0.01). Conclusions? Humanistic nursing service can improve the patient's anxiety and depression level, improve the patient's satisfaction, and reduce the nursing complaints and disputes.
