This comprehensive review synthesizes the latest advancements in understanding inflammatory disorders affecting cerebral small vessels, a distinct yet understudied category within cerebral small vessel diseases (SVD). Unlike classical SVD, these inflammatory conditions exhibit unique clinical presentations, imaging patterns, and pathophysiological mechanisms, posing significant diagnostic and therapeutic challenges. Highlighting their heterogeneity, this review spans primary angiitis of the central nervous system, cerebral amyloid angiopathy-related inflammation, systemic vasculitis, secondary vasculitis, and vasculitis in autoinflammatory diseases. Key discussions focus on emerging insights into immune-mediated processes, neuroimaging characteristics, and histopathological distinctions. Furthermore, this review underscores the importance of standardized diagnostic frameworks, individualized immunomodulation approaches, and novel targeted therapies to address unmet clinical demands.

Psoriasis is an incurable chronic inflammatory disease that requires new interventions. Here, we found that fibroblasts exacerbate psoriasis progression by promoting macrophage recruitment via CCL2 secretion by single-cell multi-omics analysis. The natural small molecule celastrol was screened to interfere with the secretion of CCL2 by fibroblasts and improve the psoriasis-like symptoms in both murine and cynomolgus monkey models. Mechanistically, celastrol directly bound to the low-density lipoprotein receptor-related protein 1 (LRP1) β-chain and abolished its binding to the transcription factor c-Jun in the nucleus, which in turn inhibited CCL2 production by skin fibroblasts, blocked fibroblast-macrophage crosstalk, and ameliorated psoriasis progression. Notably, fibroblast-specific LRP1 knockout mice exhibited a significant reduction in psoriasis like inflammation. Taken together, from clinical samples and combined with various mouse models, we revealed the pathogenesis of psoriasis from the perspective of fibroblast-macrophage crosstalk, and provided a foundation for LRP1 as a novel potential target for psoriasis treatment.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective    To investigate the clinical efficacy of minimally invasive Ivor-Lewis esophagectomy (MIILE) with reverse-puncture anastomosis. Methods    Clinical data of the patients with lower esophageal carcinoma who underwent MIILE with reverse-puncture anastomosis in our department from May 2015 to December 2020 were collected. Modified MIILE consisted of several key steps: (1) pylorus fully dissociated; (2) making gastric tube under laparoscope; (3) dissection of esophagus and thoracic lymph nodes under artificial pneumothorax with single-lumen endotracheal tube intubation in semi-prone position; (4) left lung ventilation with bronchial blocker; (5) intrathoracic anastomosis with reverse-puncture anastomosis technique. Results     Finally 248 patients were collected, including 206 males and 42 females, with a mean age of 63.3±7.4 years. All 248 patients underwent MIILE with reverse-puncture anastomosis successfully. The mean operation time was 176±35 min and estimated blood loss was 110±70 mL. The mean number of lymph nodes harvested from each patient was 24±8. The rate of lymph node metastasis was 43.1% (107/248). The pulmonary complication rate was 13.7% (34/248), including 6 patients of acute respiratory distress syndrome. Among the 6 patients, 2 patients needed endotracheal intubation-assisted respiration. Postoperative hemorrhage was observed in 5 patients and 2 of them needed hemostasis under thoracoscopy. Thoracoscopic thoracic duct ligation was performed in 1 patient due to the type Ⅲ chylothorax. TypeⅡ anastomotic leakage was found in 3 patients and 1 of them died of acute respiratory distress syndrome. One patient of delayed broncho-gastric fistula was cured after secondary operation. Ten patients with type Ⅰ recurrent laryngeal nerve injury were cured after conservative treatment. All patients were followe up for at least 16 months. The median follow-up time was 44 months. The 3-year survival rate was 71.8%, and the 5-year survival rate was 57.8%. Conclusion    The optimized MIILE with reverse-puncture anastomosis for the treatment of lower esophageal cancer is safe and feasible, and the long-term survival is satisfactory.

Objective To explore the potential mechanism of Babao Dan on primary liver cancer based on network pharmacology. Methods First, the diethylnitrosamine-induced hepatocellular carcinoma rat（HCC）model was used to observe the effects of Babao Dan. Then, the effective components in Babao Dan were detected by UPLC-MS, and the potential target sites of these effective components were predicted in the Swiss Target Prediction databases, etc. The corresponding target sites for HCC were screened using GeneCards, OMIM and Therapeutic Target Database, and the common target sites between Babao Dan and HCC were obtained after getting the intersection. The protein-protein interaction network was drawn by Cytoscape software and the STRING database, and the key molecules regulating HCC by Babao Dan were screened out. The effective target sites were subjected to GO analysis in the DAVID database and enrichment analysis in the Pathway’s KEGG. Finally, the clinical relevance of key molecules to liver cancer patients was verified by the TCGA database.

The initial prediction of the mechanism by which Babao Dan regulating liver cancer was made through UPLC-MS analysis and network pharmacology methods, indicating that Babao Dan has the characteristics of multi-component, multi-pathway, and multi-target regulation of primary liver cancer, which could provide a reference for further relevant experimental research.

Objective: To investigate the association between consumption of milk tea beverages and other sugary beverages with insomnia symptoms among college students, so as to the provide reference for promoting sleep quality among college students. Methods: From September to November 2023, a convenience sampling method was used to select 15 440 college students from seven universities in Shanghai, Jiangxi Province, Hubei Province, and Shanxi Province. A self developed questionnaire and the Insomnia Severity Index were used to assess milk tea beverage consumption, other sugary beverages and insomnia symptoms. Univariate analysis of insomnia symptoms among college students was performed using Chi square tests and Cochran-Armitage trend χ 2 tests. Multivariate Logistic regression analysis was conducted for the association between milk tea and other sugary beverage consumption with insomnia symptoms. Results: The detection rates of insomnia symptoms among college students was 40.83%. The frequency of consumption of different milk tea and various sugary drinks (juice, tea, milk, sodas,yogurt, functional drinks, coffee) per week was related to the detection trend rate of insomnia symptoms of college students ( χ 2 trend =38.38, 47.66, 74.16, 32.44, 65.78 , 38.71, 35.94, 91.59, P < 0.01 ). Multivariate analysis indicated that compared to individuals with no milk tea consumption, college students engaging in milk tea consumption had a significantly increased risk of insomnia symptoms ( OR =1.24, P <0.05). Students consuming milk tea at low to moderate frequencies (1-3, 4-5 times per week) showed a higher risk of insomnia symptoms compared to those with no consumption ( OR =1.20, 1.54, P <0.05). Furthermore, higher levels of milk tea consumption were significantly associated with insomnia symptoms (1 501-2 999 mL, OR =1.22; ≥3 000 mL, OR =1.36), and the consumption of other sugary beverages were also associated with insomnia symptoms of college students ( OR =1.10-1.55) ( P <0.05). Conclusions There is a relationship between consumption of milk tea beverage other sugary beverages with insomnia symptoms among college students. Colleges should regularly conduct dietary health education seminars to improve sleep quality among college students.

Objective:To explore effect of Glioma-associated oncogene family zinc finger 1(GLI1)on hypoxia induced trans-formation of NR8383 to M1 phenotype and development of pulmonary hypertension(PH).Methods:Fifteen adult male Wistar rats were randomly divided into control group,hypoxia PH model group and hypoxic PH with GANT61 treatment group,with 5 rats in each group.PH related indexes of rats were detected by small animal ultrasound and right cardiac catheter experiment to determine effect of GLI1 specific inhibitor GANT61 on progression of PH.Pulmonary arterial thickness was measured by HE staining.α-SMA and M1 polarization markers TNF-α and IL-1β expressions were determined by immunohistochemistry.M1 polarization markers CD86 and TNF-α expressions were determined by immunofluorescence.GLI1 expression and NF-κB protein were detected by Western blot.mRNA expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 were detected by qRT-PCR.CHIP-PCR verified that GLI1 regulates NF-κB promoter activity.IL-12 content was detected by ELISA.Rat pulmonary artery smooth muscle cells proliferation was detected by CCK-8.Results:GLI1 inhibitor GANT61 could alleviate symptoms of PH in hypoxic rats(P<0.05).Compared with hypoxic group,inhibition of GLI1 reduced expressions of TNF-α and IL-1β in rat lung tissue(P<0.05).In cell experiments,hypoxia induced M1 polarization of NR8383 by up-regulating GLI1 to activate NF-κB pathway,GLI1 overexpression increased expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 in M1 macrophages(P<0.05).NR8383 culture supernatants could stimulate pulmonary artery smooth muscle cell proliferation(P<0.05)and contribute to development of PH.Conclusion:Hypoxia activates NF-κB pathway by up-regulating GLI1 to induce M1 polarization of macrophages contributes to development of PH.
