ObjectiveTo explore the application effects of environmentally friendly reagents versus traditional reagents in tissue processing, paraffin sectioning, hematoxylin-eosin (HE) staining, special staining, and immunohistochemistry. MethodsPancreatic, renal, splenic, hepatic, pulmonary, skeletal muscle, and cardiac tissues were collected from mice and New Zealand rabbits, and randomly divided into a traditional group (Group A), an environmentally friendly reagent I group (Group B), and an environmentally friendly reagent Ⅱ group (Group C). The processed tissue sections from all three groups were subjected to paraffin sections, HE staining, phosphotungstic acid-hematoxylin staining, and Mallory trichrome staining. The pancreatic tissue sections were subjected to immunohistochemical detection of insulin protein. Evaluation criteria included tissue morphological integrity, embedding operability, section quality, and staining effects. ResultsNo significant differences were observed among the three groups of samples in terms of fixation efficacy, embedding operations, and section quality. After HE staining, all groups exhibited bright nuclear and cytoplasmic staining with clear contrast, with excellent-and-good rates of 98%, 99%, and 97% for Groups A, B, and C, respectively, showing no statistically significant differences (A vs. B, P=0.561; A vs. C, P=0.651). In phosphotungstic acid-hematoxylin staining, Groups A and C showed clear structural contrast and bright staining for striated muscle and collagen fibers, whereas Group B exhibited uneven staining. The excellent-and-good rates were 100%, 10%, and 95% for Groups A, B, and C, respectively, with significant differences between Group A and Group B (P<0.01) but no statistical difference between Group A and Group C (P=0.311). In Mallory trichrome staining, Groups A and B outperformed Group C. The excellent-and-good rates were 95%, 90%, and 15% for Groups A, B, and C, respectively, with significant differences between Group A and Group C (P<0.01), but no statistical difference between Group A and Group B (P=0.548). Immunohistochemical results showed that Group A had a clean background with no non-specific staining, while Groups B and C exhibited significant non-specific staining, with statistically significant differences in non-specific staining rates between the groups (A vs. B, 5% vs. 100%, P<0.01; A vs. C, 5% vs.100%, P<0.01). ConclusionIn HE staining, environmentally friendly reagents demonstrated effective tissue fixation and staining results comparable to traditional reagents, meeting the teaching requirements. For special staining, Group B and Group C performed better in Mallory trichrome staining and phosphotungstic acid-hematoxylin staining, respectively. However, environmentally friendly reagents exhibited non-specific staining issues in immunohistochemistry, where further optimization is required.

Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.

It is believed that psoriasis with anxiety and depression presents the pathogenesis of "depression-blood-spirit", with qi depression as the initiating factor, and that the disease mechanism is understood from three aspects, including "qi depression transforming into fire, blood stasis disturbing the spirit", "depressed fire consuming yin, causing blood dryness and spirit agitation", "qi stagnation leading to blood stasis, resulting in obstructed channels and spirit depression". The treatment proposes three methods, firstly, cooling blood and resolving depression, secondly, nourishing blood and soothing depression, and thirdly, activating blood and regulating depression, which applies prescriptions as modified Liangxue Huoxue Decoction (凉血活血汤) combined with Zhiqiao (Poncirus trifoliata), Foshou (Citrus medica), and Lianqiaoxin (Forsythia suspensa) for cooling blood and resolving depression; modified Yangxue Jiedu Decoction (养血解毒汤) combined with Baishao (Paeonia lactiflora Pall), Zhenzhumu (Margaritifera Concha), and calcined Muli (Ostreidae) for nourishing blood and soothing depression; and modified Huoxue Sanyu Decoction (活血散瘀汤) combined with Yujin (Curcuma aromatica) and Hehuanpi (Albiziae Cortex) for activating blood and regulating depression. These three methods integrate the "depression-blood-spirit" pathogenesis to achieve harmony of body and spirit by clearing blood heat, nourishing yin and blood, and removing blood stasis, complemented with medicinals that soothing the liver, calming the spirit, and regulating depression.

In recent years, sleep problems among nurses have become a prominent social focus, and sleep disorders are widespread among nurses. ICU nurses are more prone to problems such as decreased sleep quality, shorter sleep duration, and daytime sleepiness than nurses in other departments due to special and complex work environments. Sleep disorders seriously affect the physical and mental health of ICU nurses and the quality of nursing care. This paper reviews the influencing factors, interventions, and assessment tools for sleep disorders among ICU nurses in order to inform the development of effective interventions.

Chronic atrophic gastritis(CAG)is a chronic gastric disorder characterized by recurrent damage to the gastric mucosal epithelium,resulting in the reduction of intrinsic glands,with or without concurrent intestinal metaplasia.The"hyperactive stomach qi"theory,derived from Huang Di Nei Jing Su Wen Ji Zhu,proposes that the core pathogenesis of CAG lies in excessive stomach qi activity,grounded in the physiological principle of"strong yang qi in earth and weak yin qi in earth".This theory synthesizes the clinical manifestations and pathological progression of CAG,asserting that its development often involves intertwined pathological factors such as stagnation,dryness-heat,phlegm-dampness and stasis-toxicity.A triphasic therapeutic framework is proposed:the spleen qi deficiency phase,marked by impaired spleen transport function and dysregulated qi-fluid distribution,requiring spleen fortification and qi-fluid regulation;the hyperactive stomach qi phase,characterized by intensified stomach qi activity coupled with dryness-damp stagnation,necessitating stagnation resolution,dampness elimination and yin nourishment;the decline and disorder of middle qi phase,characterized by the deficiency of the middle qi,with phlegm,blood stasis and toxins forming the terminal stage.Treatment should focus on reinforcing the middle and restoring balance,detoxifying and dissipating accumulation.By exploring CAG pathogenesis and treatment through the lens of"hyperactive stomach qi",this study aimed to provide novel theoretical insights and therapeutic strategies for TCM in the prevention and treatment of CAG.
