Atopic dermatitis （AD） is an atopic disease with a complex etiology and pathogenesis resulting from the interaction of multiple factors. The NOD-like receptor pyrin domain-containing 3 （NLRP3） inflammasome is an important component of innate immunity and is involved in the onset and progression of AD， encompassing multiple processes such as inflammation， pyroptosis， and autophagy. Traditional Chinese medicine （TCM） has shown significant clinical efficacy in the treatment of AD and also offers advantages including flexible compatibility， multi-target effects， and low drug resistance. A large number of studies have shown that single Chinese medicinal components and compound prescriptions can treat atopic diseases by modulating the NLRP3 inflammasome. This article elaborates on the activation of the NLRP3 inflammasome and its influence on the pathogenesis and progression of AD， and summarizes recent studies on the mechanisms by which active constituents， extracts， and compound formulations of Chinese medicine treat AD through regulation of the NLRP3 inflammasome and related signaling pathways， with the aim of providing a reference for the clinical treatment of AD and the development of TCM.

ObjectiveTo investigate the effects of Huanglian Jiedutang （HLJDT） on cognitive function in mice with ischemic stroke （IS） and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB （NF-κB） signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion （MCAO）. Sixty C57BL/6J mice were randomly assigned to five groups （n =12 per group）， i.e.， sham operation， model， HLJDT low-dose （3.9 g·kg^-1·d^-1）， HLJDT high-dose （7.8 g·kg^-1·d^-1）， and Ginkgo biloba extract （GBE， 31.2 mg·kg^-1·d^-1）. Post-operatively， neurological deficit scores （Longa score）， cerebral infarct volume assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and brain water content were evaluated. Learning and memory were assessed using new object recognition （NOR） and fear conditioning （FC） tests. Hippocampal pathology was examined via hematoxylin and eosin （HE） staining. Immunofluorescence detected expression of glial fibrillary acidic protein （GFAP， astrocyte marker）， cellular oncogene Fos （c-Fos， neuronal activation marker）， and glutamate decarboxylase 65 （GAD65）. Western blot measured nuclear factor-κB inhibitor protein α （IκBα）， phosphorylated IκBα （p-IκBα）， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， ionic calcium binding adapter molecule 1 （Iba-1）， tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and apoptosis-related proteins， such as cleaved cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Real-time quantitative PCR （Real-time PCR） was used to assess mRNA levels of Iba-1， TNF-α， IL-1β， NF-κB p65， cleaved Caspase-3， Bax， and Bcl-2. ResultsCompared with the sham group， the model group exhibited significantly increased neurological deficit scores， brain water content， and cerebral infarct volume （P<0.01）. Hippocampal CA1 neurons were disorganized， showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced （P<0.01）. GFAP and c-Fos expression were increased， while GAD65 expression was decreased （P<0.01）. Cleaved Caspase-3 and Bax were upregulated， Bcl-2 was downregulated， and the Bax/Bcl-2 ratio was elevated （P<0.01）. Expression levels of p-IκBα， p-NF-κB p65， IL-1β， TNF-α， and Iba-1 were significantly increased （P<0.01）. Compared with the model group， HLJDT high-dose， low-dose， and GBE groups showed significant improvements in all parameters （P<0.01）. Among them， the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests （P<0.01）. In this group， GFAP and c-Fos decreased， GAD65 increased （P<0.01）， apoptosis-related protein expression was reversed， and NF-κB signaling and related inflammatory factor expression were suppressed （P<0.01）. ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS， potentially by inhibiting the NF-κB signaling pathway， thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

AIM:To observe the effect and mech-anism of cuttlebone extract regulating vascular en-dothelial growth factor(VEGF)/phosphatidylinosi-tol 3-kinase(PI3K)/protein kinase B(AKT)pathway on refractory wounds in rats.METHODS:Cuttle-bone extract(CE)was obtained by water extraction of cuttlebone.Fifty SD rats were randomly divided into negative Control group,Model group,Cuttle-bone extract low-dose(CE(L))group,Cuttlebone extract high-dose(CE(H))group,and cuttlebone ex-tract high-dose+inhibitor(CE(H)+LY294002)group.After the refractory wound model was successfully established,0.02％furacillin solution or cuttlebone extract solution were applied to the wound area of rats in each group,and the treatment was adminis-tered once a day.After 14 days of treatment for re-fractory wounds,the changes in wound healing,angiogenesis,inflammation and expression of relat-ed regulatory proteins were quantitatively ana-lyzed by measuring skin ulcer wound area,patho-logical sections,immunofluorescence staining,Eli-sa,Western blot,RT-qPCR and other methods.RE-SULTS:Compared with Model group,CE(L)and CE(H)groups can increase the number of epithelial cells and collagen,and promote the healing of re-fractory wound in rats.Serum VEGF,skin tissue mi-crovascular density,P-PI3K,P-AKT,VEGF protein ex-pression and mRNA expression levels of PI3K,Akt,VEGF and eNOS were increased(P＜0.05),while se-rum TNF-α and IL-6 levels were decreased(P＜0.05).LY294002 could partially reverse the repair-ing effect of high dose cuttlebone extract on refrac-tory wound(P＜0.05).CONCLUSION:Cuttlebone ex-tract can regulate the VEGF/PI3K/AKT signaling pathway,inhibit the inflammatory response of re-fractory wounds in rats,induce angiogenesis and promote wound healing.

Objective To evaluate the characteristics of preoperative corneal astigmatism in cataract surgery candi-dates with high myopia.Methods In this observational study,medical records of consecutive patients who underwent cataract surgery in our hospital between January 2014 and December 2023 were reviewed retrospectively.Biometric param-eters of eyes were measured preoperatively by IOL-Master optical biometry.The cataract patients were classified into a high myopia group[defined as axial length(AL)≥26.00 mm]and a control group(normal ALs,22.00 mm ≤ AL ≤25.00 mm).The characteristics of corneal astigmatism were compared between the two groups.Results Among 17 325 cataract pa-tients(17 325 eyes),2 206 patients(2 206 eyes)had high myopia and 13 429 patients(13 429 eyes)had no high myopia.In the high myopia group,1 822 eyes(82.6％)had corneal astigmatism ≥0.50 D,1 138 eyes(51.6％)had corneal astig-matism ≥1.00 D,623 eyes(28.2％)had corneal astigmatism ≥1.50 D and 314 eyes(14.2％)had corneal astigmatism ≥2.00 D.These proportions were significantly higher than those in the control group(71.9％,35.9％,15.9％and 7.3％,re-spectively;all P＜0.001).In the high myopia group,1 340 eyes(60.7％)had moderate astigmatism,147 eyes(6.7％)had high astigmatism and 922 eyes(41.8％)had with-the-rule(WTR)astigmatism.These 3 proportions were all significantly higher than those in the control group(48.9％,3.3％and 28.2％,respectively;all P＜0.001).Among high-myopia pa-tients,the corneal astigmatism was statistically greater in women than that in men(P=0.001),and the proportion of ob-lique astigmatism was higher in women than that in men(19.3％vs.15.8％,P=0.034).The proportion of against-the-rule(ATR)astigmatism increased significantly with age.In the high myopia group,the corneal astigmatism of eyes with WTR,ATR and oblique astigmatism was(1.26±0.85)D,(1.28±0.81)D and(0.89±0.71)D,respectively.They were signifi-cantly greater than those in the control group[(0.82±0.71)D,(1.06±0.68)D and(0.67±0.53)D,respectively;all P＜0.001].In the high myopia group,there were 31.8％,12.3％and 4.1％of eyes with corneal astigmatism ≥1.00 D,≥1.50 D and ≥2.00 D,respectively.All of these 3 proportions were significantly lower than those of eyes with WTR or ATR astig-matism(all P＜0.05).This finding is consistent with the tendency in the control group.Conclusion A significant bur-den of preoperative corneal astigmatism is observed in cataract surgery candidates with high myopia,with more than 50％of the patients having corneal astigmatism ≥1.00 D.The corneal astigmatism of patients with high myopia is significantly greater than that of patients with normal ALs.The proportion of moderate-to-high astigmatism is significantly higher in high-myopia patients than that in patients with normal ALs.

AIM:To evaluate the characteristics of ocular biometric parameters and the distribution of corneal astigmatism(CA)in patients with high myopia before cataract surgery.METHODS:A prospective cross-sectional study was conducted, and 695 cataract patients(695 eyes)with high myopia [defined as an axial length(AL)≥26.00 mm] scheduled to undergo cataract surgery at our hospital from January 2022 to December 2024 were consecutively enrolled, another 695 cataract patients(695 eyes)with normal ALs(22.00 mm ≤AL≤25.00 mm)who underwent cataract surgery at our hospital during the same period were included in the control group. For patients with both eyes eligible, the right eye was used for analysis. Before cataract surgery, IOL Master 700 was used to measure the ocular biometric parameters of both eyes for each patient in the two groups. The medical records and ocular biometric data in the two groups were recorded and collected.RESULTS:There were no statistically significant differences between the two groups in genger, age, corneal diameter, and central corneal thickness(all P>0.05). In the high myopia group, the mean AL was 29.20±2.61 mm, and 252 eyes(34.1%)had AL ≥30.00 mm(extremely high myopia). The mean anterior chamber depth(ACD), lens thickness, vitreous chamber depth(VCD), CA, AL/corneal radius of curvature and VCD/AL in the high myopia group were 3.45±0.40, 4.41±0.47, 21.34±2.60 mm, 1.18±0.78 D, 3.79±0.38, and 0.73±0.03, respectively, which were all greater than those in the control group(all P<0.01). In the high myopia group, 350 eyes(50.4%)had CA ≥1.00 D, 192 eyes(27.6%)had CA ≥1.50 D, and 94 eyes(13.5%)had CA ≥2.00 D, which were all higher than those in the control group(32.8%, 15.1%, and 6.6%, respectively; all P<0.001). In the high myopia group, 87 eyes(12.5%)had flat corneas, 424 eyes(61.0%)had moderate CA, and 40 eyes(5.8%)had high CA. These proportions were all higher than those in the control group(6.0%, 46.9%, and 2.9%, respectively; all P<0.001). In the high myopia group, ACD and ACD/AL were negatively correlated with AL(r=-0.162 and -0.661, respectively; all P<0.001), while both ACD and ACD/AL in the control group were positively correlated with AL(r=0.338 and 0.105, respectively; both P<0.01). In the high myopia group, CA increased with age when the patient's age was ≥50 years(r=0.197, P<0.001), which was consistent with the control group.CONCLUSION: The standardized ocular biometric data of cataract patients with high myopia before cataract surgery are helpful for ophthalmologists to accurately calculate the intraocular lens(IOLs)power and select the appropriate IOL type. The majority of high myopia patients need simultaneous correction of CA during cataract surgery.

Diabetic cataract, a prevalent ocular complication of diabetes mellitus, arises from a complex interplay of pathological mechanisms, with oxidative stress and glycation stress playing central roles. Autophagy, a critical cellular self-protection mechanism, sustains intracellular homeostasis by selectively degrading damaged organelles and misfolded proteins, thereby counteracting the detrimental effects of oxidative and glycation stress under hyperglycemic conditions. Emerging evidence indicates a synergistic interaction between glycation stress and oxidative stress, which may exacerbate autophagic dysfunction and accelerate the onset and progression of diabetic cataract. However, the precise molecular mechanisms underlying this relationship remain incompletely understood. This review systematically examines the regulatory role of autophagy inthe pathogenesis of diabetic cataract, with a particular focus on how autophagic impairment influences disease progression under the combined effects of glycation and oxidative stress. By elucidating these mechanisms, the paper aims to provide novel insights into molecular diagnostic approaches and targeted therapeutic strategies for diabetic cataract.

Objective To investigate the application of health education based on integrated behavior change theory in life management of Helicobacter pylori(Hp)positive chronic gastritis patients.Methods A total of 1 000 patients diagnosed with Hp-positive chronic gastritis in The First Affiliated Hospital of Naval Medical University between January and December 2023 were allocated into two groups using an envelope method.The control group(n=500)received conventional nursing care.The study group(n=500)were given conventional nursing care along with health education based on integrated behavior change theory.The scores of Connor-Davidson resilience scale(CD-RISC),health promotion lifestyle profile-Ⅱ(HPLP-Ⅱ),and generic quality of life inventory-74(GQOL-74)were compared between the two groups.Hp eradication rate and recurrence rate were calculated.Results After three months of intervention,the scores of CD-RISC,HPLP-Ⅱ and GQOL-74 and the eradication rate of the study group were higher than those in the control group(P<0.05),while the recurrence rate in the study group was significantly lower than that in the control group(P<0.05).Conclusion Health education based on integrated behavior change theory can enhance psychological resilience,promote the healthy lifestyle,achieve effective disease management,and ultimately improve quality of life in Hp-positive chronic gastritis patients.
