BACKGROUND:In recent years,the incidence of hyperuricemia caused by purine metabolism disorders has been increasing,which can induce inflammatory responses and lead to renal injury. OBJECTIVE:To explore the role and mechanism of solute carrier family 2 member 12(SLC2A12)in hyperuricemia-related renal injury. METHODS:Renal tubular cells(HK2 cells)were divided into five groups:HK2 group,HK2+uric acid group,HK2+uric acid+NC group,HK2+uric acid+siSLC2A12 group,and HK2+uric acid+siSLC2A12+MK-2206 group.HK2 cells were treated with uric acid and transfected with siRNA SLC2A12,followed by MK-2206 treatment to inhibit AKT expression.Cell proliferation was detected by CCK-8 assay.Apoptosis was detected by TUNEL assay.qRT-PCR and western blot assay were used to detect fibrogenic factors as well as activation of the AKT/FOXO3a pathway.The concentrations of inflammatory cytokines were measured by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:(1)Uric acid treatment inhibited cell proliferation and promoted cell apoptosis in the HK2+uric acid group compared with the HK2 group.The proliferative ability of cells in the HK2+uric acid+siSLC2A12 group was further decreased and apoptotic cells were further increased compared with the HK2 group.Compared with the HK2+uric acid+siSLC2A12 group,the HK2+uric acid+siSLC2A12+MK-2206 group showed an increase in cell proliferation and a decrease in apoptotic cells.(2)Compared with the HK2 group,the connective tissue growth factor(CTGF),α-smooth muscle actin(α-SMA)and transforming growth factor beta(TGF-β)expressions increased in the HK2+uric acid group;CTGF,α-SMA and TGF-β expression further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,the CTGF,α-SMA and TGF-β expressions decreased.(3)Compared with the HK2 group,the expression of p-AKT,FOXO3a,and p-FOXO3a elevated in the HK2+uric acid group;the expression of p-AKT further increased,while the expression of FOXO3a and p-FOXO3a decreased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,p-AKT expression decreased;FOXO3a and p-FOXO3a expression increased in the HK2+uric acid+siSLC2A12+MK-2206 group.(4)Compared with the HK2 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels increased in the HK2+uric acid group;interleukin-6,interleukin-1 β,and tumor necrosis factor α levels further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels diminished in the HK2+uric acid+siSLC2A12+MK-2206 group.(5)These findings indicate that SLC2A12 may protect against hyperuricemia-induced renal injury by counteracting uric acid-induced tubular fibrosis and inflammation through activation of the FOXO3a pathway.

Objective To explore the effect of multiparameter electroencephalogram(EEG)-guided anesthesia management on EEG burst suppression(BS)and postoperative delirium(POD)in elderly patients undergoing lower abdominal laparoscopic surgery.Methods A total of 100 elderly patients,48 males and 52 females,aged 65-85 years,BMI 18.5-28.0 kg/m2,and ASA physical status Ⅱ or Ⅲ,were enrolled for lower abdominal surgery under general anesthesia.Patients were randomly divided into two groups:multiparameter group and single parameter group,50 patients in each group.In multiparameter group,multiparameter EEG monitoring with patient statu index(PSI),spectral edge frequency(SEF),burst suppression ratio(BSR)and density spectral array(DSA)were used to guide the depth management of anesthesia.In single parameter group,single parameter PSI was used to guide the depth management of anesthesia.The total area under the hypotensive threshold of MAP(AUTMAP)was calculated,and the amount of anesthetic used during the operation and the use of vasoactive drugs,duration of anesthesia,extu-bation time,duration of PACU stay,and postoperative hospitalisation days were recorded.HR,MAP,PSI,and SEF were recorded before the induction of anesthesia,5 minutes after induction of anesthesia,5,30,and 60 minutes after incision,and at the end of surgery.The incidence,duration,and maximum BSR of in-traoperative BS,as well as the incidence of POD 1,2,and 3 days after surgery were recorded.Results There was no significant difference in AUTMAP values between the two groups.Compared with single parame-ter group,intraoperative propofol and remifentanil dosage were significantly decreased(P＜0.05),awak-ening time,PACU stay,and postoperative hospitalization time were significantly shorter in multiparameter group(P＜0.05),the PSI was significantly increased 5,30,and 60 minutes after incision and at the end of surgery,and the SEF was significantly increased 5 minutes after induction of anesthesia,5,30,and 60 minutes after induction and the end of surgery(P＜0.05).Compared with single parameter group,inci-dence of intraoperative BS was significantly decreased,duration of BS was significantly shorter,smaller maximum BSR was significantly decreased,and incidence of POD on 1 day after surgery in multiparameter group(P＜0.05).Conclusion Anesthesia management guided by multiparameter EEG can inhibit the oc-currence of BS,mitigate the degree of BS,and reduce the incidence of POD in elderly patients undergoing abdominal surgery.

Objective:To evaluate the impact of artificial intelligence continuous bowel sound auscultation recorder on enhanced recovery after surgery for patients with Crohn's disease.Methods:60 patients with Crohn's disease who underwent surgery in Sir Run Run Shaw Hospital , Zhejiang University School of Medicine in 2021 were enrolled in this trial prospectively. They were rendered to oral nutritional supplements (ONS) after surgery according to the hint given by artificial intelligence continuous bowel sound auscultation recorder or doctor's experience. In order to investigate the clinical value of artificial intelligence continuous bowel sound auscultation recorder.Results:the first postoperative flatus was earlier in the intervention group compared with control group [(58.3±1.5) h vs. (63.5±1.2) h, t=3.025, P=0.036], and the first ONS time was (18.3±0.3) h vs. (22.1±0.7) h, t=3.521, P=0.026; the incidence of postoperative complications in the intervention group was lower than that in the control group (3% vs. 7%, t=1.954, P=0.048) and the postoperative hospital stay was shorter [(7.2±0.4) d vs. (8.5±0.4) d, t=2.954, P=0.030]. The incidence of postoperative abdominal pain, abdominal distension, nausea, vomiting and fatigue in the intervention group was slightly lower than that in the control group, without statistically significant difference. Conclusion:In patient with Crohn's disease, the artificial intelligence continuous bowel sound auscultation recorder picks up accurate postoperative exhaust time, indicates the time of fist ONS after surgery, and shorten the postoperative hospital stay, without increase postoperative complication such as abdominal pain distension, accelerates postoperative recovery.

Flavonoids such as baohuoside I and icaritin are the major active compounds in Epimedii Folium(EF)and possess excellent therapeutic effects on various diseases.Encouragingly,in 2022,icaritin soft capsules were approved to reach the market for the treatment of hepatocellular carcinoma(HCC)by National Medical Products Administration(NMPA)of China.Moreover,recent studies demonstrate that icaritin can serve as immune-modulating agent to exert anti-tumor effects.Nonetheless,both production effi-ciency and clinical applications of epimedium flavonoids have been restrained because of their low content,poor bioavailability,and unfavorable in vivo delivery efficiency.Recently,various strategies,including enzyme engineering and nanotechnology,have been developed to increase productivity and activity,improve delivery efficiency,and enhance therapeutic effects of epimedium flavonoids.In this review,the structure-activity relationship of epimedium flavonoids is described.Then,enzymatic en-gineering strategies for increasing the productivity of highly active baohuoside I and icaritin are dis-cussed.The nanomedicines for overcoming in vivo delivery barriers and improving therapeutic effects of various diseases are summarized.Finally,the challenges and an outlook on clinical translation of epi-medium flavonoids are proposed.

OBJECTIVE: To explore the mechanisms of large-conductance calcium-activated potassium channel (BKCa) involved in inflammatory response in sepsis. METHODS: The serum levels of BKCa were measured by enzyme-linked immunosorbent assay (ELISA) in patients with sepsis (28 cases), patients with common infection (25 cases) and healthy people (25 cases). The relationship between levels of BKCa and acute physiology and chronic health evaluation II (APACHE II) were analyzed. Cultured RAW 264.7 cells were stimulated by lipopolysaccharide (LPS). In some experiments, a cell model of sepsis was constructed using Nigericin as the second stimulus signal. The mRNA and protein expressions of BKCa in RAW 264.7 cells stimulated with LPS (0, 50, 100, 1 000 μg/L) were measured by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blotting. RAW 264.7 cells were transfected with small interfering RNA of BKCa (siRNA-BKCa), and the levels of caspase-1 precursor (pro-caspase-1), interleukin-1β precursor (pro-IL-1β) in cell, and the levels of caspase-1 p20, IL-1β p17 of cell culture medium, and NOD-like receptor protein 3 (NLRP3), nuclear factor-κB (NF-κB) were measured by Western blotting. The apoptosis were detected by staining with propidium iodide (PI), the release rate of lactate dehydrogenase (LDH) were measured, and the expression of apoptotic protein Gasdermin D (GSDMD) was measured by Western blotting to evaluate the effect of silencing BKCa on cell pyrosis. RESULTS: The level of serum BKCa in patients with sepsis was significantly higher than that in patients with common infection and health peoples (ng/L: 165.2±25.9 vs. 102.5±25.9, 98.8±20.0, both P < 0.05). In addition, the level of serum BKCa in patients with sepsis was significantly positively correlated with APACHE II score (r = 0.453, P = 0.013). LPS could construct a sepsis cell model by which LPS could promote BKCa expression in mRNA and protein with a concentration-dependent manner. The mRNA and protein expressions of BKCa in the cells stimulated by 1 000 μg/L LPS were significantly higher than that in the blank group (0 μg/L) [BKCa mRNA (2^-ΔΔCt): 3.00±0.36 vs. 1.00±0.16, BKCa/β-actin: 1.30±0.16 vs. 0.37±0.09, both P < 0.05]. Compared with the control group, the ratios of caspase-1 p20/pro-caspase-1 and IL-1β p17/pro-IL-1β in the model group were significantly increased (caspase-1 p20/pro-caspase-1: 0.83±0.12 vs. 0.27±0.05, IL-1β p17/pro-IL-1β: 0.77±0.12 vs. 0.23±0.12, both P < 0.05), however, transfection of siRNA-BKCa induced the decrease both of them (caspase-1 p20/pro-capase-1: 0.23±0.12 vs. 0.83±0.12, IL-1β p17/pro-IL-1β: 0.13±0.05 vs. 0.77±0.12, both P < 0.05). Compared with the control group, the number of apoptotic cells, LDH release rate and GSDMD expression in the model group were significantly increased [LDH release rate: (30.60±8.40)% vs. (15.20±7.10)%, GSDMD-N/GSDMD-FL: 2.10±0.16 vs. 1.00±0.16, both P < 0.05], however, transfection of siRNA-BKCa induced the decrease both of them [LDH release rate: (15.60±7.30)% vs. (30.60±8.40)%, GSDMD-N/GSDMD-FL: 1.13±0.17 vs. 2.10±0.16, both P < 0.05]. The mRNA and protein expressions of NLRP3 in sepsis cells were significantly higher than those in the control group [NLRP3 mRNA (2^-ΔΔCt): 2.06±0.17 vs. 1.00±0.24, NLRP3/GAPDH: 0.46±0.05 vs. 0.15±0.04, both P < 0.05]. However, the expression of NLRP3 after siRNA-BKCa transfection was significantly lower than that in model group [NLRP3 mRNA (2^-ΔΔCt): 1.57±0.09 vs. 2.06±0.17, NLRP3/GAPDH: 0.19±0.02 vs. 0.46±0.05, both P < 0.05]. Compared with the control group, the NF-κB p65 nuclear transfer of sepsis cell were significantly increased (NF-κB p65/Histone: 0.73±0.12 vs. 0.23±0.09, P < 0.05). However, the NF-κB p65 expression in the nucleus were decreased after siRNA-BKCa transfection (NF-κB p65/Histone: 0.20±0.03 vs. 0.73±0.12, P < 0.05). CONCLUSIONS BKCa is involved in the pathogenesis of sepsis, and its possible mechanism is to activate NF-κB/NLRP3/caspase-1 signaling pathway to induce inflammatory factor production and cell death.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To explore the specific changes and correlations of sex hormones and lipid metabolism in overweight and obese boys aged 9-12 years.Methods:Seventy-two male subjects (9 to 12 years old) were divided into normal weight group ( n=42), overweight group ( n=15), and obese group ( n=15). Plasma sex hormone levels and lipid levels were detected by chemiluminescence immunoassay and ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC/QTOF/MS). All data were analyzed by multivariate statistics analysis. Results:(1) The serum concentration of sex hormone-binding globulin (SHBG) in obese group and overweight group was significantly lower than that in normal weight group, and the serum concentration of SHBG in obese group was significantly lower than that in overweight group ( P<0.05). The serum concentrations of dehydroepiandrosterone (DHEA) in overweight and obese group were significantly higher than those in normal weight group ( P<0.05). (2) There were 171 kinds of differential lipid compounds between normal weight group and overweight group, 218 species of differential lipid compounds between normal weight group and obese group, and 34 species of differential lipid compounds between overweight and obese group. Among them, 150 kinds of lipid compounds in normal weight group were significantly different from those in overweight and obese group. (3) SHGB was positively correlated with phosphatidyl cholines (PC) (20∶0/0∶0) and PC[18∶1(9E)/0∶0]( r=0.6, P<0.05), DHEA was positively correlated with diacylglycerol (DG)[17∶2(9Z, 12Z)/22∶0/0∶0]( r=0.5, P<0.05). Conclusions:9-12 years old overweight and obese boys had early growth and development, but sex hormone levels were not synchronized with growth and development. The serum DHEA level in overweight and obese boys was significantly increased, while the level of DG [17∶2 (9Z, 12Z)/22∶0/0∶0] was significantly increased, and the serum SHGB concentration was significantly decreased, while the vast majority of PC was significantly down-regulated. The mechanism of these changes needs to be further studied.
