ObjectiveTo investigate whether Huanglian Jiedutang can inhibit neutrophil infiltration in the brains of middle cerebral artery occlusion (MCAO) mice by regulating the expression of neutrophil-related chemokines in exosomes, thereby achieving therapeutic effects. MethodsA total of 130 male specific pathogen-free (SPF) C57BL/6J mice were randomly divided into four groups: Sham-operated group, MCAO model group, Huanglian Jiedutang group (6 g·kg-1), and Ginaton group (21.6 mg·kg-1), with 10 mice in the Ginaton group and 40 mice in each of the remaining three groups. Mice in the Huanglian Jiedutang group and the Ginaton group were administered the corresponding drugs by oral gavage once daily at a volume of 0.15 mL·(10 g)-1 for 7 consecutive days, while the sham-operated and model groups received an equal volume of saline via the same route. After 7 days, MCAO surgery was performed. The distal and proximal ends of the right common carotid artery (CCA) were ligated, a small incision was made between the two ligatures, and a silicone rubber-coated monofilament with a rounded tip was inserted into the lumen to occlude the CCA. The filament was left in place for 1 h to establish a focal cerebral ischemia model. At 24 h after modeling, mice were evaluated. Neurological function was assessed using the Longa score. Cerebral infarct volume was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Cerebral blood flow was observed by laser speckle imaging. Hematoxylin and eosin (HE) staining and Nissl staining were used to observe pathological changes in brain tissues. Exosomes were isolated from mouse plasma and brain tissues by ultracentrifugation and molecular size exclusion and identified by electron microscopy, particle size analysis, and protein blotting. Long-chain RNA libraries of exosomes were constructed and sequenced. Real-time quantitative reverse transcription polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of inflammatory factors and neutrophil-related chemokines in exosomes from plasma and brain tissues of each group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the protein expression of inflammatory factors and neutrophil-related chemokines in exosomes from brain tissues of each group. Immunohistochemistry was used to detect the expression of the neutrophil-specific protein myeloperoxidase (MPO) in the brains of mice in each group. ResultsCompared with the sham-operated group, the model group showed decreased neurological function scores (P<0.01), obvious cerebral infarction (P<0.01), reduced cerebral blood flow (P<0.01), neuronal necrosis in the brain, and decreased numbers of Nissl bodies (P<0.01). The mRNA expression levels of IL-1β, MPO, CXCL1, CXCL2, CXCL3, CXCL10, CCL2, and CCL3 in exosomes from plasma and brain tissues were significantly increased (P<0.05, P<0.01). The protein expression levels of IL-1β, MPO, CXCL2, and CXCL10 in exosomes from brain tissues were increased (P<0.05, P<0.01), and MPO-positive rates and mean optical density values in brain tissues were elevated (P<0.01). Compared with the model group, the Huanglian Jiedutang group and the Ginaton group showed increased neurological function scores (P<0.05), reduced cerebral infarct volume (P<0.01), restored cerebral blood flow (P<0.01), reduced necrotic cells in the brain, and increased numbers of Nissl bodies (P<0.01). In the Huanglian Jiedutang group, the mRNA expression levels of IL-1β, MPO, CXCL1, CXCL2, CXCL3, CXCL10, CCL2, and CCL3 in exosomes from plasma and brain tissues were decreased (P<0.05, P<0.01). The protein expression levels of IL-1β, MPO, CXCL2, and CXCL10 in exosomes from brain tissues were reduced (P<0.05, P<0.01), and MPO-positive rates and mean optical density values in brain tissues were decreased (P<0.01). ConclusionHuanglian Jiedutang can effectively regulate the expression of neutrophil-related chemokines in exosomes from plasma and brain tissues of MCAO mice, thereby reducing neutrophil infiltration in the brain and achieving therapeutic effects.

BACKGROUND:Finite element modeling,as an important engineering analysis technique,has been widely used in various fields of bioengineering research.However,there is little literature on what material properties should be selected for each anatomical structure of the knee joint finite element modeling at different ages for different research purposes.OBJECTIVE:To summarize the material properties of knee joint finite element models at different ages based on previous knee joint finite element studies.METHODS:The search terms were"knee,finite element,material selection,ligament injury,osteoarthritis,elderly,children,young people"in Chinese and English.Articles were searched on CNKI and PubMed,with a timeframe of 1950 to 2024.According to inclusion and exclusion criteria,108 articles were finally included for summary.RESULTS AND CONCLUSION:Children's knee bone density will increase with age,reaching peaks in adulthood.From middle-aged to the age,the elastic modulus of knee joint femur,tibia,fibula,and patella will decrease with age,and then return to the elastic modulus of childhood.The elastic modulus of children and adult cartilage is basically the same,and the elastic modulus of the elderly increases.With the increase of age,the elastic modulus of the knee ligament will decrease to a certain extent,but there is no significant difference in the elastic modulus of the knee ligament of young people and the elderly.With the increase of age,the loss of mechanical integrity of the knee meniscus will damage the biomechanical function of the tissue and disturb the various anisotropic biomechanical responses that are effectively carried and transmitted by the tissue.Knee joint finite element modeling can be used to deeply understand the biomechanical characteristics of the knee joints,develop new implanted materials,predict knee joint diseases,improve surgical technology,and guide patients to rehabilitate exercise.

Objective:To explore the efficacy and safety of the ballistic-ultrasound-negative pressure three-in-one energy platform (Trilogy) for micro-channel percutaneous nephrolithotomy (mini-PCNL).Methods:A retrospective analysis was conducted on the clinical data of 140 patients with upper urinary tract stones treated at Tianjin Medical University Second Hospital from February to October 2024. All patients underwent mini-PCNL and were divided into the holmium laser group and the Trilogy group based on the stone fragmentation equipment used during the procedure. There were 69 patients in the holmium laser group and 71 in the Trilogy group. The two groups had similar mean ages (55.1±10.2 years vs. 53.4±10.8 years), male patient proportions (50 cases, 72.5% vs. 50 cases, 70.4%), body mass indices (25.2±3.6 kg/m 2 vs. 25.3±4.0 kg/m 2), incidence rates of hypertension (29 cases, 42.0% vs. 31 cases, 43.7%), diabetes (15 cases, 21.7% vs. 12 cases, 16.9%), mean cumulative stone lengths (39.2±12.6 mm vs. 35.9±14.8 mm), total stone volumes preoperatively (6 184.3±3 653.5 mm 3 vs. 5 644.9±4 173.8 mm 3), mean CT values for stones (1 138.2±264.3 HU vs. 1 151.3±208.0 HU), stone locations (ureter 14 cases, 20.3% vs. 22 cases, 31.0%; kidney 48 cases, 69.6% vs. 39 cases, 54.9%; both ureter and kidney 7 cases, 10.1% vs. 10 cases, 14.1%), preoperative mean urinary white blood cell counts [9.6(3.6, 31.2) cells/HPF vs. 11.9(3.8, 34.5) cells/HPF], proportions of patients with preoperative urinary white blood cells (+ + + ; 23 cases, 33.3% vs. 25 cases, 35.2%), nitrite positivity rates (4 cases, 5.8% vs. 3 cases, 4.2%), and urine culture positivity rates (12 cases, 17.4% vs. 18 cases, 25.4%) showed no statistically significant differences. The proportion of patients with moderate or higher hydronephrosis in the holmium laser group was lower than that in the Trilogy group (32 cases, 46.4% vs. 47 cases, 66.2%, P=0.018). The holmium laser group utilized holmium laser lithotripsy, where stone fragments were either flushed out with a vortex or retrieved with a stone basket. The Trilogy group employed a three-in-one energy platform to break the stones. This device incorporated pneumatic ballistic, ultrasound, and negative pressure suction capabilities within the same metallic probe, allowing the stone to be fragmented into small pieces while simultaneously performing ultrasonic negative pressure stone clearance. The parameters for the three-in-one energy platform were adjusted based on intraoperative conditions, typically setting negative pressure at 30%-50%, ultrasound power at 80%-100%, ballistic power at 80%, and frequency at 8 Hz. During the stone fragmentation process, the ballistic device fragmented the stones while ultrasound further reduced larger fragments and removed them. Some fragments that were difficult to break could also be flushed out or retrieved with a stone basket. The efficiency of stone clearance (volume of stones cleared per unit time) was compared between the two groups, as well as the stone-free rates on postoperative day 1 and day 30. Stone clearance time was defined as the duration from the start of fragmentation to the placement of the nephrostomy tube. Changes in postoperative white blood cells, hemoglobin, and albumin levels compared to preoperative levels, as well as the incidence of Clavien-Dindo complications, were compared between the two groups. Equipment failure incidents were recorded (fiber fracture in the holmium laser group indicating it could not be used; probe fracture in the Trilogy group). Patients were sub-grouped based on stone CT values into CT ≥ 1 000 HU and CT < 1 000 HU categories to compare stone clearance efficiency between the two devices within each sub-group. In the CT≥1 000 HU sub-group, there were 51 cases in the holmium laser group and 54 in the Trilogy group, there were no significant differences in preoperative total stone volume (6 785.0±3 902.3 mm 3 vs. 5 678.1±4 297.7 mm 3). In the CT < 1 000 HU sub-group, there were 18 cases in the holmium laser group and 17 in the Trilogy group. There were no significant differences between the groups in preoperative total stone volume (4 482.2±2 110.6 mm 3 vs. 5 530.9±3 845.3 mm 3). Results:The overall stone clearance efficiency in the Trilogy group was higher than that in the holmium laser group (87.9±35.7 mm 3/min vs. 77.1±24.3 mm 3/min, P=0.038). There were no significant differences in residual stone volume before discharge [5.5(0, 84.0) mm 3 vs. 5.3(0, 175.0) mm 3], stone clearance time (79.4±43.2 min vs. 66.6±49.7 min), or the proportion of patients using stone baskets during the procedure (33 cases, 47.8% vs. 36 cases, 50.7%). Postoperative changes in white blood cells, hemoglobin, and albumin compared to preoperative levels were not significantly different [(4.1±2.9)×10 9/L vs. (3.3±2.2)×10 9/L; (-2.9±10.5) g/L vs. (-1.6±9.3) g/L; (-2.5±3.6) g/L vs. (-1.8±5.0) g/L] Furthermore, there were no statistically significant differences in equipment failure rates (1 case, 1.4% vs. 4 cases, 5.6%), stone-free rates (postoperative day 1: 43 cases, 62.3% vs. 47 cases, 66.2%; postoperative day 30: 50 cases, 72.5% vs. 53 cases, 74.6%), or Clavien-Dindo complication rates (grade Ⅰ: 11 cases, 15.9% vs. 8 cases, 11.3%; grade Ⅱ: 2 cases, 2.8% vs. 0 cases; grade Ⅲ: 1 case, 1.4% vs. 0 cases). In the CT ≥ 1 000 HU sub-group, the clearance time for the holmium laser was longer than that for Trilogy (93.3±41.0 min vs. 74.6±51.9 min, P=0.044), there were no significant differences in residual stone volume before discharge [6.3(1.6, 173.8) mm 3 vs. 4.5(0, 69.0) mm 3] between the two groups. In the CT < 1 000 HU sub-group, the overall stone clearance efficiency of the Trilogy group exceeded that of the holmium laser group (134.2±38.0 mm 3/min vs. 105.5 ± 7.1 mm 3/min, P=0.004), there were no significant differences between the groups in residual stone volume before discharge [0(0, 51.1) mm 3 vs. 16.3(0, 957.2) mm 3], or stone clearance time (40.2±18.1 min vs. 39.1±27.5 min). Conclusions:In mini-PCNL surgery, the stone fragmentation efficiency of the three-in-one lithotripsy energy platform is superior to that of the holmium laser, while the overall complication rate is comparable to that of the holmium laser.
