Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

Objective: The aim of this study is to explore the predictive value of biparametric magnetic resonance imaging(bpMRI)for pelvic lymph node metastasis in prostate cancer patients with PSA≤20 μg/L and establish a nomogram. Methods: The imaging data and clinical data of 363 patients undergoing radical prostatectomy and pelvic lymph node dissection in the First Affiliated Hospital of Nanjing Medical University from July 2018 to December 2023 were retrospectively analyzed. Univariate analysis and multivariate logistic regression were used to screen independent risk factors for pelvic lymph node metastasis in prostate cancer, and a nomogram of the clinical prediction model was established. Calibration curves were drawn to evaluate the accuracy of the model. Results: Multivariate logistic regression analysis showed extrocapusular extension (OR=8.08,95%CI=2.62-24.97, P<0.01), enlargement of pelvic lymph nodes (OR=4.45,95%CI=1.16-17.11,P=0.030), and biopsy ISUP grade(OR=1.97,95%CI=1.12-3.46, P=0.018)were independent risk factors for pelvic lymph node metastasis. The C-index of the prediction model was 0.834, which indicated that the model had a good prediction ability. The actual value of the model calibration curve and the prediction probability of the model fitted well, indicating that the model had a good accuracy. Further analysis of DCA curve showed that the model had good clinical application value when the risk threshold ranged from 0.05 to 0.70.Conclusion: For prostate cancer patients with PSA≤20 μg/L, bpMRI has a good predictive value for the pelvic lymph node metastasis of prostate cancer with extrocapusular extension, enlargement of pelvic lymph nodes and ISUP grade≥4.

Objective:To investigate the clinical efficacy and safety of collagen injection in improving periorbital aging.Methods:The data of patients receiving collagen injections treated for periorbital aging at Hangzhou Xueran Medical Beauty Clinic from December 2023 to July 2024 were analyzed retrospectively. Pre-injection facial photographs were taken to assess periorbital aging severity. A domestic collagen filler (35 mg/ml premixed with 0.3% lidocaine) was injected. First, 30 G sharp needle was used to inject filler into the periorbital periosteal layer through 6 points on each side. After that, 27 G blunt needle was used to give falloped flat injection in the subcutaneous and under the orbicularis oculi muscle, respectively, from 2 points on each side. Total doses (1-6 ml) were determined by aging severity. Based on prior pain perception experiences, injection sites were categorized into three zones. Psychological interventions were implemented during left facial injections, while right facial injections served as non-intervention controls. Post-procedure care included erythromycin ointment application and ice compression. Patient images were obtained immediately post-treatment, at 1 month, and 3 months after treatment. Periorbital aging rating scale (PARS) was assessed by third-party. The higher the scale rating, the more severe the periorbital aging. After treatment, a reduction of 1 grade from the pre-treatment rating was regarded as effective improvement, and a reduction of ≥2 grades was regarded as significant improvement. Global aesthetic improvement scale (GAIS) was assessed by the patients. The full score was 5, the higher the score, the greater the improvement. The patient satisfaction was evaluated by self-made scale. The effectiveness of psychological intervention was evaluated by patients immediately after treatment. The complications were followed up and recorded. SPSS 26.0 software was used for statistical analysis, and the measurement data were expressed as Mean±SD. Paired sample t-test was used to compare the same patient before and after treatment. Counting data was expressed as cases (%). Results:A total of 45 patients were included, including 10 males and 35 females, aged (35.6±8.0) years (25-55 years). All patients were followed up. PARS evaluation showed that, PARS rating at immediately after injection, 1 month and 3 months after injection[(1.3±0.7), (1.1±0.6), (1.2±0.7) grade] was significantly decreased ( t=23.45, 25.38, 26.36, all P<0.001), compared with that before treatment[(2.2±0.6) grade]. All patients achieved significant or effective improvement immediately and 1 month after treatment. Only 1 patient’s rating recovered to the pre-treatment level 3 months after treatment. After treatment, GAIS scores remained stable as 4.8±0.4 (immediate) vs. 4.9±0.3 (1-month) vs. 4.6±0.5 (3-month), showing no significant differecnce ( t=-1.98, 1.52; P=0.058, 0.135). 44 cases (97.8%) reported satisfied results and maintained improvement with high satisfaction, while 1 case (2.2%) noted mostly loss at 3 months. All patients (100%) perceived enhanced comfort during left-side psychological interventions. Adverse events included 1 case (2.2%) of transient ecchymosis resolving within 5 days. No allergies, nodules, or vascular complications occurred. Natural dynamic expressions were maintained in all patients at 3 months. Conclusion:Periocular collagen injection can effectively improve the signs of aging around the eyes and exhibit good long-term effect. The implementation of psychological interventions during the injection treatment can effectively alleviate fear and anxiety, significantly enhance treatment comfort.

Objective:To investigate the distribution characteristics and analyze the clinical significance of dermatophagoides pteronyssinus allergen components in children with allergic rhinitis and asthma in Shenzhen.Methods:This study was a cross-sectional study. The clinical data of children with allergic rhinitis and asthma induced by dust mites admitted to the allergy clinic of Shenzhen Children′s Hospital from 2021 to 2024 were collected and the serum sIgE levels of dermatophagoides pteronyssinus, dermatophagoides farinae (Der p, Der f) and dermatophagoides pteronyssinus components (Der p 1, Der p 2, Der p 10, Der p 23) were detected by magnetic bead chemiluminescence method. The correlation between dermatophagoides pteronyssinus allergen components and clinical data of children was analyzed. According to the diagnosis, the children were divided into allergic rhinitis (AR) group and AR with asthma (ARAS) group. According to the age, the children were divided into preschool age (5 years ≤age<7 years), school age (7 years ≤age<10 years) and adolescence (10 years ≤age≤15 years). The expression differences of dermatophagoides pteronyssinus components among AR group and ARAS group and different age groups were compared.Results:A total of 314 children with allergic rhinitis and asthma caused by dust mites were included in the study, of whom 112 were male and 202 were female. There were 188 cases of AR and 126 cases of ARAS, aged 5-15 years, with a median age of 7.54 years and an average age of (8.02±2.24) years. BMI was 13.89-31.76 kg/m 2,the median BMI was 15.87 kg/m2 and average BMI was (16.55±3.05) kg/m2. There was not statistically significant difference in gender, age, BMI, blood eosinophils, blood basophils, FeNO, FVC and FEV1 between the AR group and the ARAS group ( P>0.05). There was significant difference in FEV1/FVC and small airway function indexes MMEF, MEF75%, MEF50% and MEF25% between the AR group and the ARAS group ( P<0.05). In the 314 children, the dermatophagoides pteronyssinus allergen components sensitization rates were in the order of Der p 1 (97.1%), Der p 2 (89.8%), Der p 23 (55.1%), Der p 10 (8.6%), and the difference in the positive rate was statistically significant (χ 2=658.31, P<0.001). There was not significant difference in Der p 1, Der p 2 and Der p 10 among children of different ages ( P>0.05). There was significant difference in Der p 23 among children of different ages (χ 2=7.29, P=0.03). A correlation analysis showed that Der p, Der f, Der p 1 and Der p 2 had a high positive correlation ( P<0.001). Eosinophils are positively correlated with Der p, Der f, Der p 1, Der p 2, Der p 10 and Der p 23 ( P<0.001). FeNO is positively correlated with Der p, Der f, and Der p 23 ( P<0.05). Small airway function indicators MMEF, MEF50% and MEF25% are negatively correlated with Der p, Der f and Der p 1 ( P<0.05). The sIgE levels of Der p, Der f, Der p 1, Der p 2 and Der p 10 in the AR group were significantly lower than those in the ARAS group ( P<0.05). In the ARAS group, 120 cases (95.24%) showed positive results for at least 2 dermatophagoides pteronyssinus components, while 71 cases (56.35%) showed positive results for at least 3 dermatophagoides pteronyssinus components. In the AR group, 171 cases (90.96%) showed positive results for at least 2 dermatophagoides pteronyssinus components, while 94 cases (50.00%) showed positive results for at least 3 dermatophagoides pteronyssinus components. Conclusion:Der p 1, Der p 2 and Der p 23 may be the main dermatophagoides pteronyssinus allergen components that induce allergic rhinitis and asthma in Shenzhen City. The elevation of sIgE levels in the dermatophagoides pteronyssinus components can aggravate the severity of lower airway eosinophilic inflammation and airway obstruction. Attention should be paid to the detection of dermatophagoides pteronyssinus components in children with poor response to dust mite-allergen specific immunotherapy.
