Neurodegenerative diseases are often associated with inflammatory mechanisms, where persistent or excessive inflammatory responses can lead to neuronal damage and subsequent pathological changes. In acute neurological conditions such as stroke or traumatic brain injury, inflammation is a key factor that triggers acute neuronal injury and long-term sequelae. In chronic neurodegenerative diseases, including Alzheimer's disease, cognitive dysfunction, Parkinson's disease, and multiple sclerosis, the chronic activation of inflammation is closely related to gradual degeneration of neurons. Resolvin D1 (RvD1), an endogenous pro-resolving mediator, plays a crucial role in controlling the intensity and duration of inflammation by inhibiting excessive activation of immune cells, modulating the release of pro-inflammatory cytokines, and maintaining the integrity of the blood-brain barrier. This review focuses on the mechanisms of RvD1 in mediating inflammatory damage in major neurological diseases, aiming to provide theoretical support for a deeper understanding of disease mechanism, optimized therapeutic strategies, and enhanced outcome.

Objective To analyze the effects of glucocorticoid stent implantation combined with nasal endoscopic surgery on nasal ventilation function and serum levels of eosinophil cationic protein(ECP),fibronectin(Fn)and aquaporin-1(AQP-1)in patients with chronic sinusitis with nasal polyp(CSwNP).Methods 60 patients with CSwNP from January 2022 to February 2023 were included in the study,and then they were divided into experimental group and control group,with 30 cases in each,using random number table method.The experimental group was treated with glucocorticoid stent implantation based on the original nasal endoscopic surgery,and the control group was treated with nasal endoscopic surgery,and both groups were treated until 12 weeks after surgery.The two groups of nasal symptoms,quality of life,nasal structure and ventilation function,serum levels of ECP,Fn,AQP-1,and adverse reactions were compared.Results Compared before the treatment,scores of nasal mucosal structure(Lund-Mackay scale),nasal symptom visual analogue scale(VAS)(including:nasal obstruction,runny nose,stuffy head,decreased sense of smell,nasal dryness/scab)and serum levels of ECP were decreased,distance from minimum nasal cross section to anterior nostril(DCAN)was shortened in two groups 12 weeks after treatment,and the experimental group was lower than the control group,the differences were statistically significant(P<0.05).Compared before the treatment,12 weeks after treatment,the nasal minimum cross-sectional area(NMCA),score of world health organization abbreviated quality of life(WHOQOL-100),nasal cavity volume(NCV),serum levels of Fn,AQP-1 were increased in two groups,and the experimental group was higher than the control group,the differences were statistically significant(P<0.05).During treatment,the incidence of adverse reactions was similar between the two groups(P>0.05).Conclusion Glucocorticoid stent implantation combined with nasal endoscopic surgery can control nasal symptoms in patients with CSwNP,improve nasal structure and ventilation function,regulate serum levels of ECP,Fn,AQP-1,and improve patients'quality of life.

Objective To investigate the correlation between the level of oxidative stress indicators in placental tissues and placental perfusion level in twin-to-twin transfusion syndrome (TTTS). Methods A total of 105 cases of dichorionic monoamniotic monozygotic twin pregnant women were included in the study. They were divided into control group of 90 cases and observation group of 15 cases based on whether TTTS occurred during pregnancy. The levels of oxidative stress indicators[malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX)]in placental tissues below the attachment points of the two umbilical cords in the two groups were detected. The maximum diameters of arterio-arterial (AA) anastomosis, veno-venous (VV) anastomosis, and arterio-venous (AV) anastomosis, as well as the difference ratio of placental tissue areas (PTD), were compared between the two groups. The correlation between the levels of oxidative stress indicators in placental tissues and placental perfusion level was analyzed. Results Compared with placental A and placental B in the control group, the MDA level in the placental tissues of the blood supply end and the blood recipient end in the observation group was increased, while the SOD and GSH-PX levels were decreased, and the maximum diameter of AA anastomosis was reduced, there were statistically significant differences (P < 0.05). In the observation group, the MDA level in the placental tissues of the blood supply end was higher than that of the blood recipient end, the SOD and GSH-PX levels were lower than those of the blood recipient end, and the maximum diameter of AA anastomosis was smaller than that of the blood recipient end, with statistically significant differences (P < 0.05). The maximum diameters of AV anastomosis and PTD in the observation group were larger than those in the control group (P < 0.05). There was no significant difference in the maximum diameter of VV anastomosis between the two groups (P>0.05). Pearson correlation analysis showed that there were no significant correlations of MDA, SOD and GSH-PX levels with the maximum diameter of AA anastomosis and PTD in the placental tissues of the control group (P>0.05).In the placental tissues of the blood supply end and the blood recipient end in the observation group, MDA levels showed a strong negative correlation with the maximum diameter of AA anastomosis and a strong positive correlation with the maximum diameter of AV anastomosis and PTD (P < 0.05). SOD and GSH-PX levels showed strong positive correlations with the maximum diameter of AA anastomosis and strong negative correlations with the maximum diamete of AV anastomosis and PTD (P < 0.05). Conclusion There is a significant imbalance of oxidative stress in placental tissues of TTTS pregnant women, and the decrease in antioxidant activity of placental tissues may be an important cause of placental perfusion injury.

AIM: To evaluate the bioequivalence of two candesartan cilexetil tablet formulations in healthy Chinese subjects after administration of a single dose, and an artificial neural network model was established to predict the candesartan plasma concentration, and provide a basis for clinical rational use of drugs. METHODS: Thirty-two healthy Chinese subjects were enrolled for oral administration of a single 8 mg dose of candesartan cilexetil tablet (test or reference product) under fasting or fed conditions to conduct a bioequivalence study. The bioequivalence results were used to build a back-propagation artificial neural network model by MATLAB software, and the model was internally and externally verified to predict the plasma concentration. RESULTS: Under both fasting and fed conditions, the C

To explore the potential associations between perceived stress and health-promoting behaviors based on the theoretical schema of the middle-range theory of adaptation to chronic illness. From January to May 2021, a convenience sampling method was used to recruit 230 young and middle-aged patients with metabolic syndrome who underwent physical examination in the inpatient center of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. The Health-Promoting Health Profile-Ⅱ, Chinese Perceived Stress Scale, Coping and Adaptation Processing Scale-Short Form, and Multi-dimensional Scale of Perceived Social Support were used in the cross-sectional study. The chain mediation effect procedure and bootstrap sampling test were used to examine the mediating role of adaptability and social support between perceived stress and health-promoting behaviors. The mean score of health-promoting behaviors was 100.0±14.6, the mean score of perceived stress was 22.0± 6.9, the mean score of adaptability was 47.0±6.1, and the mean score of social support was 63.8±10.8. Perceived stress had a negative impact on patients' health-promoting behaviors (=-0.309, <0.05). The adaptability (effect size= -0.112, 95%:-0.199~-0.038) and social support (effect size= -0.032, 95%:-0.083~played a mediating role and a chain mediating role in the process of perceived stress influencing patients' health-promoting behaviors (effect size= -0.045, 95%:-0.093~-0.020). Adaptability and social support play an intermediary role between perceived stress and health-promoting behaviors in young and middle-aged patients with metabolic syndrome. Healthcare professionals can motivate patients to develop healthy behaviors by developing intervention strategies on adaptability and social support.

Objective: To investigate the difference in invasiveness between vulvovaginal candidiasis(VVC) and recurrent vulvovaginal candidiasis(RVVC) strains, and to explore the effect of strains with different secreted aspartate protease(Sap) on vaginal local immunity. Methods: Vaginal secretions of VVC and RVVC patients were collected for fungus identification.Candida albicans(C.albicans) were taken for drug sensitivity analysis, 25 S rDNA genotyping, and detection of secreted aspartate protease(Sap) and phospholipase(Plb) activity.C.albicanswith different Sap activity were cultured with vaginal epithelial cells, and the levels of Interleukin(IL)-4, IL-8, IL-17 in cell supernatant were measured by ELISA. Results: Sap activity of VVCC.albicanswas stronger than that of RVVC. After infection withC.albicans, the secretion of IL-4, IL-8 and IL-17 by vaginal epithelial cells was higher, and IL-8 and IL-17 appeared earlier and lasted longer.C.albicanswith strong Sap enzyme activity could stimulate vaginal epithelial cells to secrete more cytokines. Conclusion Except for the Sap activity, there was no significant difference in the invasiveness between VVC and RVVC strains.C.albicanscould activate the vaginal host immune response in a short time. The lower Sap activity ofC.albicansin RVVC patients may be related to the protective factors secreted by the vaginal epithelium.
