OBJECTIVE To analyze the components migrating to blood and metabolites of Polygonum cuspidatum in rats with acute gouty arthritis （AGA）. METHODS SD rats were randomly divided into blank group， model group and P. cuspidatum group （10 g/kg， by raw material）， with 6 rats in each group. Except for blank group， AGA model was induced in the remaining groups by injecting potassium oxonate and sodium urate； meanwhile， they were administered corresponding drug solutions or water intragastrically， once a day， for 10 consecutive days. The histopathological morphology of the knee joint tissues in rats was observed；rat serum samples were collected， and the components migrating to blood and metabolites of P. cuspidatum were analyzed by using UPLC-Q-Exactive-Orbitrap-MS. RESULTS Following the intervention with P. cuspidatum， the histopathological morphology of the knee joint synovial tissue in AGA rats showed significant improvement， with reduced inflammatory cell infiltration and hyperplasia， and the preservation of the honeycomb-like structure integrity. In both positive and negative ion modes， a total of 67 chemical components were detected in the serum of rats from P. cuspidatum group， including 25 prototype components and 42 metabolites. The involved compound types encompassed stilbenes， anthraquinones， naphthols， and flavonoids， among others. The metabolic reactions identified included methylation， acetylation， sulfation， and glucuronidation. Notably， compounds such as polydatin， resveratrol and emodin were capable of entering the bloodstream in their prototype forms and undergoing in vivo metabolism. CONCLUSIONS Compounds such as polydatin， resveratrol and emodin are likely to be the active components responsible for the anti-AGA effects of P. cuspidatum.

Objective To identify clinical risk factors for early major adverse cardiovascular events (MACEs) following surgical correction of supravalvar aortic stenosis (SVAS). Methods Patients who underwent SVAS surgical correction between 2002 and 2019 in Beijing and Yunnan Fuwai Cardiovascular Hospitals were included. The patients were divided into a MACEs group and a non-MACEs group based on whether MACEs concurring during postoperative hospitalization or within 30 days following surgical correction for SVAS. Their preoperative, intraoperative, and postoperative clinical data were collected for multivariate logistic regression. Results This study included 302 patients. There were 199 males and 103 females, with a median age of 63.0 (29.2, 131.2) months. The incidence of early postoperative MACEs was 7.0% (21/302). The multivariate logistic regression model identified independent risk factors for early postoperative MACEs, including ICU duration (OR=1.01, 95%CI 1.00-1.01, P=0.032), intraoperative cardiopulmonary bypass (CPB) time (OR=1.02, 95%CI 1.01-1.04, P=0.014), aortic annulus diameter (OR=0.65, 95%CI 0.43-0.97, P=0.035), aortic sinus inner diameter (OR=0.75, 95%CI 0.57-0.98, P=0.037), and diameter of the stenosis (OR=0.56, 95%CI 0.35-0.90, P=0.016). Conclusion The independent risk factors for early postoperative MACEs include ICU duration, intraoperative CPB time, aortic annulus diameter, aortic sinus inner diameter, and diameter of the stenosis. Early identification of high-risk populations for MACEs is beneficial for the development of clinical treatment strategies.

Objective To investigate the alleviation of Nippostrongylus brasiliensis infection on dextran sulfate sodium salt (DSS)-induced ulcerative colitis in mice, and to explore the underlying mechanism. Methods Thirty male C57BL/6J mice of the SPF grade, each weighing approximately 25 g, were randomly divided into three groups, including the blank control group (NC group), DSS modeling group (DSS group), and N. brasiliensis treatment group (Nb + DSS group), of 10 mice in each group. Mice in the DSS group were orally administered with 3.5% DSS daily since day 1 (D0) for 6 successive days, and given normal drinking water since D6, and animals in the Nb + DSS group were subcutaneously injected with the third-stage larvae of N. brasiliensis at a dose of 500 larvae per mice 5 days prior to D0, followed by oral administration with 3.5% DSS daily since D0 for 6 successive days and normal drinking water since D6, while mice in the NC group were given normal drinking water. Mouse body weight and stool were observed and the disease activity index (DAI) was scored in each group during the study period. All mice were sacrificed on D9. The mouse colon length was measured, and mouse colon specimens were subjected to hematoxylin-eosin (HE) staining and histopathological scoring. In addition, the mRNA and protein expression of interleukin (IL)-1β and IL-10 was quantified in mouse colon specimens using quantitative fluorescent real-time PCR (qPCR) assay and enzyme-linked immunosorbent assay (ELISA), and the mRNA and protein expression of mucosal repair-associated molecules zonula occludens-1 (ZO-1), mucin 2 (MUC2) and claudin-1 was detected in mouse colon specimens using qPCR assay and immunofluorescence assay. Results The mice body weights, DAI scores and colon lengths were (26.26 ± 1.93), (22.39 ± 1.65), (25.00 ± 1.58) g (F = 8.06, P < 0.01); (1.89 ± 0.34), (0.47 ± 0.39), 0 points (F = 57.61, P < 0.000 1); and (42.50 ± 5.75), (56.20 ± 5.96) mm and (61.17 ± 7.88) mm (F = 13.72, P < 0.001) in the NC, DSS and Nb + DSS groups on D9, respectively, and elevated mouse body weight (P < 0.05), reduced DAI score (P < 0.000 1) and increased colon length (P < 0.01) were observed in the Nb + DSS group relative to the DSS group on D9. Pathological examinations showed that the colonic crypts were relatively intact and the inflammatory cell infiltration was lower in the mouse colon specimens in the Nb + DSS group than in DSS the group. There was a significant difference in the histopathological scores of mouse colon specimens among the NC group (0 point), the DSS group [(2.00 ± 1.22) points] and the Nb + DSS group [(0.20 ± 0.45) points] (F = 10.71, P < 0.01), respectively, and the histopathological score of mouse colon specimens was significantly higher in the DSS group than in the NC and Nb + DSS groups (both P values < 0.01). qPCR assay quantified that the relative IL-10 and IL-1β mRNA expression was 1.25 ± 0.08, 0.44 ± 0.14 and 1.30 ± 0.45 (F = 10.66, P < 0.01), and 0.22 ± 0.13, 1.14 ± 0.31 and 0.41 ± 0.19 (F = 16.89, P < 0.001) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and higher IL-10 mRNA expression and lower IL-1β mRNA expression were found in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.01). The relative MUC2, claudin-1 and ZO-1 mRNA expression was 0.87 ± 0.25, 0.34 ± 0.26 and 4.21 ± 0.55 (F = 121.60, P < 0.000 1), 1.05 ± 0.41, 0.16 ± 0.09 and 0.22 ± 0.11 (F = 14.00, P < 0.01), and 1.03 ± 0.10, 0.60 ± 0.11 and 1.64 ± 0.28 (F = 32.16, P < 0.000 1) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and significantly higher MUC2 and ZO-1 mRNA expression was quantified in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.05). The mean fluorescence intensities of ZO-1 and claudin-1 were 17.18 ± 2.08, 12.38 ± 1.21 and 18.06 ± 2.59 (F = 8.95, P < 0.01) and 13.50 ± 1.63, 9.66 ± 2.03 and 13.61 ± 0.97 (F = 6.96, P < 0.05) in mouse colon specimens in the NC, DSS and Nb + DSS groups, respectively, and the mean fluorescence intensities of ZO-1 and claudin-1 were significantly greater in mouse colon specimens in the Nb + DSS group than in the DSS group (both P values < 0.05). Conclusion N. brasiliensis infection may remarkably alleviate DSS-induced ulcerative colitis in mice through promoting expression of anti-inflammatory cytokines, inhibiting expression of pro-inflammatory cytokines and facilitating mucosal repair in colon tissues.

Objective: To understand the association between positive and negative childhood experiences with uncertainty stress in college students. Methods: From March to May 2021, 1 816 college students in Jiangsu and Hubei Province were randomly selected, and an electronic structured questionnaire was used to collect the general characteristics, positive and adverse childhood experience, and uncertainty stress. Logistic regression was used to explore the association between positive and negative childhood experiences with uncertainty stress. Results: The reported rate of uncertainty stress among 1 816 college students was 27.5%( n =500). Logistic regression results showed that the risk of uncertainty stress among students with childhood abuse experience was 2.10 times higher than that of control group( OR=2.10, 95%CI =1.64-2.70). The probability of uncertainty stress in students with high self awareness was 37% of those with low self awareness( OR=0.37, 95%CI =0.24-0.57). The probability of uncertainty stress in students with positive predictable life was 32% of those without( OR=0.32, 95%CI =0.13-0.77). Conclusion College students are vulnerable population for psychological stress. Both positive and adverse childhood experience are associated with the occurrence of uncertainty stress. Early screening for with adverse childhood experiences in adolescents is recommended to protect physical and mental health.

Objective:To evaluate the effect of general anesthesia guided by electroencephalography (EEG) monitoring on postoperative delirium (POD) in elderly patients with non-acute fragile brain function.Methods:Sixty patients of both sexes with non-acute fragile brain function, aged 65-85 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with body mass index of 18-30 kg/m 2, undergoing hip replacement, were divided into 2 groups ( n=30 each) by a random number table method: conventional general anesthesia group (group C) and general anesthesia guided by EEG monitoring group (group E). Anesthesia was maintained by intravenous infusion of propofol 50-150 μg·kg -1·min -1 and remifentanil 0.05-0.30 μg·kg -1·min -1 and intermittent intravenous boluses of rocuronium.In group E, the dose of anesthetic was reduced when the EEG burst-suppression ratio≥10% for more than 1 min or anesthesia index (AI) <40.If the situation mentioned above still existed after 1 min, the dose of anesthetic was continued to be reduced or norepinephrine was injected intravenously.In group C, the amount of intraoperative anesthesia was adjusted according to the changes in hemodynamics.Norepinephrine 4-10 μg or dopamine 1 mg was given intravenously in the light of the patients′ heart rates when intraoperative hypotension occurred.At 10 min after anesthesia induction, immediately after skin incision, immediately at the end of surgery and at 1 h after surgery, blood samples were obtained from the artery and jugular venous bulb for blood gas analysis and for calculation of jugular bulb blood oxygen content (CjvO 2), artery-jugular bulb blood oxygen content difference (Ca-jvO 2), cerebral oxygen uptake rate (CERO 2) and jugular-arterial blood lactate concentration difference (Djv-aLac). The emergence time, amounts of intraoperative anesthetics, use of noradrenaline, cumulative time of EEG burst inhibition and duration of AI<40 were recorded.The development of POD was assessed within 5 days after surgery by the confusion assessment method for the intensive care unit and the duration was recorded. Results:Compared with group C, recovery time, cumulative time of EEG burst inhibition and duration of AI<40 were significantly shortened, the intraoperative consumption of propofol and remifentanil was decreased, the requirement for intraoperative noradrenaline was increased, CjvO 2 was increased, Ca-jvO 2 and CERO 2 were decreased immediately at the end of surgery and at 1 h after surgery, the incidence of POD within 5 days after surgery was decreased, and POD duration was shortened in group E ( P<0.05). Conclusion:General anesthesia guided by EEG monitoring can reduce the development of POD in elderly patients with non-acute fragile brain function.

Objective To establish a two-dimensional high-performance liquid chromatography method for the determination of tigecycline in human cerebrospinal fluid, which can be used for the drug monitoring in patients with intracranial infection. Methods The quantification was carried out by an external standard method. The first-dimension column was a Aston SNX5 phenyl chromatographic column (50 mm×4.6 mm, 5 μm) with ammonium phosphate (pH was adjusted with ammonium hydroxide to 7.5)-methanol (45∶55, V/V) as the mobile phase and the flow rate was 1.2 ml/min. The second-dimension chromatographic column was Aston SC5 C₁₈ (275 mm×4.6 mm, 5 μm), with ammonium phosphate (pH was adjusted with ammonium hydroxide to 7.4)-ammonium phosphate (pH was adjusted with ammonium hydroxide to 3.0)- acetonitrile (30∶50∶20, V/V/V) as the mobile phase and the flow rate was 1.0 ml/min. The detection wavelength was 340 nm. The temperature was 40 ℃ and the injection volume was 200 μl. Results The calibration curve of tigecycline showed good linearity from 64.5 to 1 290.0 ng/ml in human cerebrospinal fluid (r=0.999 8). The RSD of intra and inter-day precision were less than 5.0% with the detection accuracy of 98.80%−106.51%. Conclusion This method is simple, quick, accurate, specific and sensitive. It meets the requirements of tigecycline determination in clinical human cerebrospinal fluid, which offers the individualized therapeutic assurance for patients with intracranial infection.

With the rapid development of tumor subjects and the advance of medical technology,tumor mortality is declining in spite of the increase in tumor incidence.The male survivors pay more and more attention to their prognosis to improve the quality of their life.In the meantime,whether they could produce their own offspring become the main concern of tumor patients with good prognosis.However,until now,male tumor patients,their relatives,different social sectors and even some of our health workers,havent noticed the importance of fertility preservation and long-term fertility desires of male patients with tumor which will lead to declined or even irreversible sterility induced by the lack of fertility preservation before anti-tumor therapy.It's an important way to do fertility counseling,learn the risk of their treatment plans and choose the appropriate technique of fertility preservation which will improve prognosis quality of life of male tumor patients.This article will review the effects of tumor and the treatment on male fertility,their subjective needs and concerns,main methods for fertility preservation and the domestic and foreign research present situation.

BACKGROUNDDrug-eluting stents (DES) with durable polymer have significantly reduced restenosis and target vessel revascularization compared with bare metal stents. Durable polymer has been linked with persistent inflammation of vessel wall and delayed endothelial healing that may increase the risk of late and very late stent thrombosis. This study sought to evaluate the efficacy and safety of HELIOS completed biodegradable polymer sirolimus-eluting stent (SES) in de novo coronary lesions.

METHODSTotally, 287 patients with one or two de novo coronary lesions (lesion length ≤ 38 mm and reference vessel diameter 2.5-4.0 mm) were enrolled in the HOPE study, a prospective, multicenter, randomized, non-inferiority trial. Patients were randomized to treatment either with HELIOS completed biodegradable polymer SES (n = 142) or PARTNER durable polymer SES (n = 145). The primary endpoint was angiographic in-stent late lumen loss (LLL) at 9-month follow-up. The secondary endpoint included stent thrombosis and major adverse cardiac events including cardiac death, myocardial infarction (MI) and target lesion revascularization (TLR).

RESULTSThe 9-month in-stent LLL in the HELIOS group was similar to the PARTNER group, (0.16 ± 0.22) mm vs. (0.19 ± 0.30) mm (P = 0.28). The difference and 95% confidence interval were -0.03 (-0.09, 0.04), and the P value for non-inferiority <0.01. Major adverse cardiovascular event (MACE) occurred in 7.9% vs. 8.2%, MI in 2.4% vs. 3.0%, TLR in 5.5% vs. 3.0%, and stent thrombosis in 0 vs. 1.5%; and events were comparable between the HELIOS group and PARTNER group at three-year follow-up (all P > 0.05). The three-year cardiac death was lower in the HELIOS group, but with no significant difference, 0 vs. 3.0% (P = 0.12).

CONCLUSIONSIn the HOPE trial, the novel completed biodegradable polymer SES HELIOS was non-inferior to the durable polymer SES PARTNER with respect to nine-month in-stent LLL in de novo coronary lesions. The incidence of other clinical endpoints was low for both of the stents in three-year follow-up.
