BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Cancer represents a major worldwide disease burden marked by escalating incidence and mortality. While therapeutic advances persist, developing safer and precisely targeted modalities remains imperative. Nanomedicines emerges as a transformative paradigm leveraging distinctive physicochemical properties to achieve tumor-specific drug delivery, controlled release, and tumor microenvironment modulation. By synergizing passive enhanced permeation and retention effect-driven accumulation and active ligand-mediated targeting, nanoplatforms enhance pharmacokinetics, promote tumor microenvironment enrichment, and improve cellular internalization while mitigating systemic toxicity. Despite revolutionizing cancer therapy through enhanced treatment efficacy and reduced adverse effects, translational challenges persist in manufacturing scalability, longterm biosafety, and cost-efficiency. This review systematically analyzes cutting-edge nanoplatforms, including polymeric, lipidic, biomimetic, albumin-based, peptide engineered, DNA origami, and inorganic nanocarriers, while evaluating their strategic advantages and technical limitations across three therapeutic domains: immunotherapy, chemotherapy, and radiotherapy. By assessing structure-function correlations and clinical translation barriers, this work establishes mechanistic and translational references to advance oncological nanomedicine development.

The purpose of the present study was to investigate the effects of resistance combined with aerobic chrono-exercise on the common carotid artery elasticity and hemodynamics. 24 healthy young men (21.96±0.43 years old) underwent a single acute resistance combined with aerobic exercise intervention at eight time periods (6, 8, 10, 12, 14, 16, 18, and 20 o'clock). The axial flow velocity and diameter waveforms of the common carotid artery were measured, and the hemodynamics were calculated using the classical hemodynamic theory before exercise, immediately after exercise, 10 min and 20 min after exercise. The results showed that during exercise recovery, systolic and mean pressures decreased more markedly after exercise at 8 o'clock (P < 0.05); At 20 min post-exercise, arterial stiffness index and pressure-strain elastic modulus after exercise at 6 o'clock were reduced compared with the resting state, but were significantly elevated after exercise at 20 o'clock (P < 0.05). Immediately after exercise, the pressure rise was higher after exercise at 6 o'clock and the mean wall shear stress was higher after exercise at 20 o'clock (P < 0.05). These results suggest that resistance combined with aerobic chrono-exercise produces different effects on common carotid artery hemodynamics in young men. A single acute session of resistance combined with aerobic exercise at 8 o'clock is more effective in lowering blood pressure. Exercise at 6 o'clock is beneficial to improve arterial elasticity but is not recommended for young male individuals with cardiovascular disease risks because of the excessive increase in blood pressure immediately after exercise. Exercise at 20 o'clock is more effective in improving wall shear stress but is accompanied by elevated arterial stiffness indices and pressure-strain elastic modulus. These results provide a scientific basis for healthy young men in choosing the time of exercise by exploring the common carotid artery elasticity and hemodynamic-related indices.

Objective Exploring the effect of Percutaneous angular vertebroplasty(PCVP)on functional recovery in elderly patients with osteoporotic vertebral compression fractures(OVCF).Methods Retrospective selection of clinical data from 108 OVCF patients admitted to our hospital from August 2020 to December 2022.According to the different surgical methods,52 cases were divided into a control group(percutaneous vertebroplasty)and an observation group(percutaneous vertebroplasty)with 56 cases;Compare the recovery of vertebral body function,imaging related parameters,functional impairment and lumbar function,surgical related conditions,gait,and complications between the two groups.Results The intraoperative blood loss in the observation group was less than that in the control group[(10.65±3.52)ml vs.(13.11±3.66)ml,P＜0.05],the number of intraoperative fluoroscopy was less than that of control group[(14.21±4.27)vs.(17.04±4.25),P＜0.05],there was no statistically significant difference in the total clinical effective rate between the observation group of 89.28％and the control group of 86.53％(P＞0.05).After 2 months of surgery,the imaging related parameters,functional impairment,lumbar function,surgical and gait related conditions in the control group were better than those in the control group(P＜0.05).There was no statistically significant difference in the incidence of incision infection,nerve root injury,and recurrent fractures between the two groups(P＞0.05),but the leakage rate of bone cement in the observation group was lower than that in the control group(P＜0.05).Conclusion Both surgeries can effectively improve the level of lumbar vertebral function in OVCF patients.PVCP has advantages in increasing the height of the anterior and posterior edges of the vertebral body,reducing the Cobb angle,and relatively fewer intraoperative fluoroscopy times and bleeding.The incidence of bone cement leakage is lower,making it more safe.

Sepsis is a potentially fatal condition characterized by the failure of one or more organs due to a disordered host response to infection. The development of sepsis is closely linked to immune dysfunction. As a result, immunotherapy has gained traction as a promising approach to sepsis treatment, as it holds the potential to reverse immunosuppression and restore immune balance, thereby improving the prognosis of septic patients. However, due to the highly heterogeneous nature of sepsis, it is crucial to carefully select the appropriate patient population for immunotherapy. This review summarizes the current and evolved treatments for sepsis-induced immunosuppression to enhance clinicians' understanding and practical application of immunotherapy in the management of sepsis.

Objective To analyze the correlation between serum levels of long non-coding RNA cyclin-de-pendent kinase inhibitor 2B antisense RNA 1(lncRNA CDKN2B-AS1),and microRNA-184(miR-184)in pa-tients with acute coronary syndrome(ACS)and the occurrence of coronary artery restenosis(RS)after percu-taneous coronary intervention(PCI)treatment.Methods A total of 288 ACS patients who underwent PCI treatment in the hospital from February 2020 to March 2023 were selected.According to the results of follow-up angiography at 6 months after surgery,they were separated into a RS group of 96 cases and a non RS group of 192 cases.The quantitative real-time PCR(qRT-PCR)method was applied to detect the relative expression levels of serum lncRNA CDKN2B-AS1 and miR-184.Pearson correlation was applied to analyze the correlation between serum lncRNA CDKN2B-AS1 and miR-184.The factors affecting the occurrence of RS in ACS pa-tients after PCI were analyzed using multivariate Logistic regression analysis.Receiver operating characteristic(ROC)curve was applied to analyze the evaluation value of serum lncRNA CDKN2B-AS1 and miR-184 for the occurrence of RS in ACS patients after PCI.Results Compared with the non RS group,the serum lncRNA CDKN2B-AS1 level in the RS group was obviously increased,while the miR-184 level was obviously reduced(P＜0.05).There were statistically significant differences in the levels of high-sensitivity C-reactive protein(hs-CRP),interleukin-18(IL-18),total bilirubin(TBIL),and cardiac troponin Ⅰ(cTnⅠ)between the two groups(P＜0.05).Pearson correlation analysis showed that there was a obvious negative correlation(r=-0.427,P＜0.05)between the expression levels of serum lncRNA CDKN2B-AS1 and miR-184 in ACS pa-tients.Multivariate Logistic regression analysis results showed that lncRNA CDKN2B-AS1,hs-CRP,IL-18,and cTnⅠ were risk factors affecting the occurrence of RS in ACS patients after PCI,while miR-184 and TBIL were protective factors affecting the occurrence of RS in ACS patients after PCI(P＜0.05).ROC curve re-sults showed that the area under the curve(AUC)of serum lncRNA CDKN2B-AS1,miR-184,and their com-bination in evaluating the occurrence of RS in ACS patients after PCI was 0.787,0.844,and 0.929,respective-ly,and the AUC of the combined evaluation the occurrence of RS in ACS patients after PCI was obviously higher than those of serum lncRNA CDKN2B-AS1 and miR-184 alone(Zcombination-lncRNACDKN2B-AS1=4.490,Zcombination-miR-184=3.429,all P＜0.05).Conclusion The serum lncRNA CDKN2B-AS1 level in ACS patients is obviously elevated,while miR-184 level is obviously reduced,which is correlated with the occurrence of RS in ACS patients after PCI.Both are factors that affect the occurrence of RS in ACS patients after PCI,and the combination of the two has better evaluation effect on the occurrence of RS in ACS patients after PCI.

OBJECTIVE: To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective. METHODS: Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ₊TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction. RESULTS: TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45⁺ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01). CONCLUSIONS TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.
