As a traditional Chinese medicine (TCM), borneol has shown superior ability for anti-inflammatory and analgesic activities when coupled with other active ingredients from ancient times. Furthermore, borneol is believed to improve blood concentration and bioavailability of drugs. Thus, it has been paired with various TCM formulas since ancient time. The physiological barriers in human can cause significant limitations in drug efficiency as the drug is primarily restricted from entering into blood and brain. Borneol has been proven to enhance the permeability of biological barriers such as the blood-brain, transdermal, corneal, and intestinal barriers. Moreover, growing interest has been shown in the drug delivery system design for trans-barrier transport involving borneol. Nano-drug delivery system with increased surface area and improved active sites, has been applied to increase the bioactivity of water insoluble drugs. Nano-drug delivery system has been used to enhance drug efficacy by reducing the time of action as compared to conventional administration approach of TCM formulas. Given its ability to enhance cross-barrier permeation and drug efficacy, borneol has been integrated into TCM formulas of drug delivery system for precise and prolonged targeting at tumor sites. However, the design and preparation of a drug delivery system consisting of borneol still face great challenges. Current research fails to unravel the difference in mechanism of action between nano-drug delivery systems comprised of borneol and conventional drug systems coupled with borneol. Enhanced penetration of borneol in drug delivery system is rarely verified compared to conventional administration with identical drug formulation consisting of borneol regarding dosage and medical indications. This study outlines the current state of research on the properties, formulation and pharmacological effects of borneol, allowing cross-comparison of borneol coupled with single compound and classical TCM formulas for various medical indications. This study aims to provide insights into the design of borneol-based enhanced cross-barrier delivery drug formulation, and the potential development of nano-drug system for TCM formulas with borneol for enhanced bioavailability.

Objective:To analyze the clinical characteristics, treatment options, and prognosis of intranasal reactive hemangioma associated with camrelizumab therapy.Methods:Clinical data from patients with intranasal reactive hemangioma associated with camrelizumab treated at Nanfang Hospital of Southern Medical University from February 2021 to April 2022 were collected, including patients′ demographics, clinical symptoms, endoscopic lesion characteristics, enhanced MRI results of the sinuses, pathological examination results, treatment plans, and disease outcomes at the last follow-up.Results:A total of 5 patients with intranasal reactive hemangioma were included, comprising 3 males and 2 females, with ages ranging from 21 to 61 years. The primary diseases of these patients included advanced primary liver cancer and nasopharyngeal carcinoma with liver and lung metastases. All patients presented with recurrent nasal bleeding and progressively worsening nasal obstruction, rated as grade 2 adverse reactions. The onset of intranasal reactive hemangioma was observed after 2 to 15 cycles of camrelizumab injections, with lesions primarily located in the common nasal passage and nasopharynx. Endoscopically, intranasal reactive hemangiomas appeared as dark red, narrow-based, and easily bleeding tumor-like lesions. Enhanced MRI showed mild to moderate heterogeneous enhancement. All patients underwent endoscopic resection of hemangioma via a lesion-targeted technique, with the surgical procedure confined to the removal of the grossly visible tumor mass and 5 mm surrounding mucosal margins around the tumor bed. Postoperative pathological examination revealed hemangioma characteristics, including variably sized vascular lumens and endothelial cell proliferation. Follow-up duration ranged from 6 to 12 months, during which none of the patients experienced recurrence of intranasal reactive hemangioma.Conclusion:Prompt surgical excision of camrelizumab-induced intranasal reactive hemangioma is recommended upon diagnosis to mitigate bleeding complications.

OBJECTIVE: To investigate the correlation between nucleated red blood cell (NRBC) level on the first day of intensive care unit (ICU) admission and 28-day mortality in adult septic patients, and to evaluate the value of NRBC as an independent predictor of death. METHODS: Single-cell transcriptomic analysis was performed using the GSE167363 dataset from the Gene Expression Omnibus (including 2 healthy controls, 3 surviving septic patients, and 2 non-surviving septic patients). A retrospective clinical analysis was conducted using the America Medical Information Mart for Intensive Care-IV (MIMIC-IV) database, including adult patients (≥ 18 years) with first-time admission who met the Sepsis-3.0 criteria, excluding those without NRBC testing on the first ICU day. The demographic information, vital signs, laboratory test indicators, disease severity score and survival data on the first day of admission were collected. The restricted cubic spline (RCS) curve was used to determine the optimal cut-off value of NRBC for predicting 28-day mortality in patients. Patients were divided into low-risk and high-risk groups based on this cut-off value for intergroup comparison, with Kaplan-Meier survival curve analysis conducted. Independent risk factors for 28-day mortality were analyzed using Logistic regression and Cox regression analysis, followed by the construction of regression models. RESULTS: NRBC were detected in the peripheral blood of septic patients by single-cell transcriptomic. A total of 1 291 sepsis patients were included in the clinical analysis, with 576 deaths within 28 days, corresponding to a 28-day mortality of 44.6%. RCS curve analysis showed a nonlinear relationship between the first-day NRBC level and the 28-day mortality. When NRBC ≥ 1%, the 28-day mortality of patients increased significantly. Compared to the low-risk group (NRBC < 1%), the high-risk group (NRBC ≥ 1%) had significantly higher respiratory rate, heart rate, sequential organ failure assessment (SOFA), and simplified acute physiology score II (SAPSII), and significantly lower hematocrit and platelet count. The high-risk group also had a significantly higher 28-day mortality [49.8% (410/824) vs. 35.5% (166/467), P < 0.05], and shorter median survival time (days: 29.8 vs. 208.6, P < 0.05). Kaplan-Meier survival curve showed that compared with the low-risk group, the survival time of high-risk group was significantly shortened (Log-rank test: χ ² = 25.1, P < 0.001). After adjusting for potential confounding factors including body mass, temperature, heart rate, respiratory rate, mean arterial pressure, serum creatinine, pulse oximetry saturation, hemoglobin, hematocrit, Na⁺, K⁺, platelet count, and SOFA score, multivariate regression analysis confirmed that NRBC ≥ 1% was an independent risk factor for 28-day mortality [Logistic regression: odds ratio (OR) = 1.464, 95% confidence interval (95%CI) was 1.126-1.902, P = 0.004; Cox regression: hazard ratio (HR) = 1.268, 95%CI was 1.050-1.531, P = 0.013]. CONCLUSIONS NRBC ≥ 1% on the first day of ICU admission is an independent risk factor for 28-day mortality in septic patients and can serve as a practical indicator for early prognostic assessment.

Objective To explore the feasibility of integrated imaging of portal vein and hepatic vein with"three low-contrast agents"combined with energy spectrum CT technology.Methods A total of 100 patients with enhanced abdominal CT scans were selected.The patients were randomly divided into two groups.The patients of experimental group(n=50)were injected with the isotonic con-trast agent iodixanol(320 mg I/mL)at a flow rate of 3 mL/s and a total volume of 1.2 mL/kg,and underwent energy spectrum CT scan in the portal venous phase.The patients of control group(n=50)were injected with the sub-hypertonic contrast agent iohexol(350 mg I/mL)at a flow rate of 5 mL/s and a total volume of 1.5 mL/kg,and underwent conventional multi-phase spiral CT enhancement scan.The image quality and radiation dose of portal vein and hepatic vein were compared between the two groups.Results The CT value of main portal vein in the experimental group was higher than that in the control group,and the difference was statistically sig-nificant(P＜0.05).There was no statistical significance in main portal vein contrast-to-noise ratio(CNR),main portal vein signal-to-noise ratio(SNR),hepatic vein CT value,and hepatic vein CNR between the two groups(P＞0.05).The SNR and image standard deviation(SD)of the hepatic vein in the control group were better than those in the experimental group(P＜0.05).There was no statistical significance in the subjective scores of portal vein and hepatic vein between the two groups(P＞0.05).The volume CT dose index(CTDIvol),dose length product(DLP),and effective dose(ED)of the portal venous phase spectrum CT scan in the experimental group were lower than those of the conventional single-phase spiral CT scan in the control group(P＜0.05).Conclusion"Three low-contrast agents"combined with energy spectrum CT technology can realize integrated imaging of portal vein and hepatic vein in late portal vein,and can reduce radiation dose.

To evaluate the modification of allergic dermatitis on the association between PM exposure and allergic rhinitis in preschool children. This cross-sectional study was based on a questionnaire conducted between June 2019 and June 2020 to caregivers of children aged 3 to 6 years in the kindergartens of 7 Chinese cities to collect information on allergic rhinitis and allergic dermatitis. A mature machine learning-based space-time extremely randomized trees model was applied to estimate early-life, prenatal, and first-year exposure of PM 1, PM 2.5 and PM 10 at 1 km×1 km resolution. A combination of multilevel logistic regression and restricted cubic spline functions was used to quantitatively assess whether allergic dermatitis modifies the associations between size-specific PM exposure and the risk of childhood allergic rhinitis. The results showed that out of 28 408 children, 14 803 (52.1%) were boys and 13 605 (47.9%) were girls; the age of children ranged from 3.1 to 6.8 years, with a mean age of (4.9±0.9) years, of which 3 586 (12.6%) were diagnosed with allergic rhinitis. Among all children, 17 832 (62.8%) were breastfed for more than 6 months and 769 (2.7%) had parental history of atopy. A total of 21 548 children (75.9%) had a mother with an educational level of university or above and 7 338 (29.6%) had passive household cigarette smoke exposure. The adjusted ORs for childhood allergic rhinitis among the children with allergic dermatitis as per interquartile range (IQR) increase in early-life PM 1(9.8 μg/m 3), PM 2.5 (14.9 μg/m 3) and PM 10 (37.7 μg/m 3) were significantly higher than the corresponding ORs among the children without allergic dermatitis [ OR: 1.45, 95% CI (1.26, 1.66) vs. 1.33, 95% CI (1.20, 1.47), for PM 1; OR: 1.38, 95% CI (1.23, 1.56) vs. 1.32, 95% CI (1.21, 1.45), for PM 2.5; OR: 1.56, 95% CI (1.31, 1.86) vs. 1.46, 95% CI (1.28, 1.67), for PM 10]. The interactions between allergic dermatitis and size-specific PM exposure on childhood allergic rhinitis were statistically significant ( Z value=19.4, all P for interaction<0.001). The similar patterns were observed for both prenatal and first-year size-specific PM exposure and the results of the dose-response relationship were consistent with those of the logistic regression. In conclusion, allergic dermatitis, as an important part of the allergic disease progression, may modify the association between ambient PM exposure and the risk of childhood allergic rhinitis. Children with allergic dermatitis should pay more attention to minimize outdoor air pollutants exposure to prevent the further progression of allergic diseases.
