Objective:To explore the short- and medium-term clinical outcomes of covered stent implantation in the treatment of transplant renal artery stenosis (TRAS).Methods:A retrospective analysis was conducted on the clinical data of 12 consecutive patients with TRAS (transplant renal artery stenosis) who underwent covered stent implantation in Henan Provincial People′s Hospital from January 2021 to December 2024. The changes in indicators such as serum creatinine (Cr), blood urea nitrogen (BUN), mean arterial pressure (MAP), peak systolic velocity (PSV), intrarenal resistance index (RI), and the diameter of the stenotic site were analyzed before the operation, one week after the operation, six months after the operation, and 12 months after the operation. Repeated measures analysis of variance was used to investigate the changes of each observation index over time.Results:The surgery was successfully performed on all 12 patients, with a technical success rate of 100%. Among them, 8 cases used self-expanding covered stents, and 4 cases used balloon-expandable covered stents. One week, six months and twelve months after the surgery, the levels of Cr, BUN, PSV and MAP were all lower than those before the surgery. The RI and the diameter of the stenotic site were significantly increased compared with those before the surgery, the difference was statistically significant ( P<0.05). During the perioperative period and the postoperative follow-up period, no surgery-related complications were found. Conclusion:The implantation of the covered stent can effectively relieve the stenosis of the transplant renal artery, significantly improve renal function, and reduce blood pressure levels in TRAS patients, while maintaining excellent short-to medium-term clinical outcomes.

Objective To observe the value of advanced patient motion correction(APMC)technology for improving imaging quality of low-dose pediatric chest CT.Methods Ninety-six children who received low-dose chest CT scan were retrospectively enrolled.CT images were reconstructed using full reconstruction technique(FULL)or APMC for both lung window and mediastinal window.Then the imaging qualities were subjectively evaluated according to image clarity,degree of motion artifacts,sharpness of structural edges and overall quality.The indexes of objective evaluation of imaging quality included the mean CT values of unit density pixel within ROI on lung window and mediastinal window,the standard deviation of CT values(SDCT)representing image noise,as well as signal-to-noise ratio(SNR).Sobel operator edge detection was performed on images,recording the mean gray level(G)and the standard deviation of gray value in Sobel(SDsobel)within ROI.Comparisons were made between FULL reconstruction and corrected images with APMC reconstruction in terms of subjective and objective evaluations,as well as parameters obtained from Sobel output images.Results Compared to FULL reconstruction,APMC corrected images showed reduced motion artifacts,improved edge structure sharpness and enhanced overall image quality(all P＜0.05),while there was no significant difference of image clarity(P＞0.05).Meanwhile,with APMC reconstructions,the mean CT values,SDCT on lung window and SDCT on mediastinal window increased(all P＜0.05),but there was no significant difference for the mean CT values on mediastinal window(P＞0.05),and SNR on both lung window and mediastinal window decreased(both P＜0.05).Besides,for Sobel output images,compared to FULL reconstruction,APMC reconstruction had increased G and SDsobel on both lung window and mediastinal window(all P＜0.05).Conclusion APMC technology applicated in low-dose chest CT scan of children could effectively reduce motion artifacts,improve edge clarity and imaging quality,hence enhance diagnostic sensitivity.

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

Objective:To compare the effect of self-radiopaque markers guiding physician-modified fenestration, chimney technique and hybrid Ⅳb technique on reconstruction of left subclavian artery (LSA) in endovascular treatment of aortic dissection (TEVAR).Methods:The clinical and follow-up data of 312 TEVAR patients treated with LSA blood supply reconstruction technology from Jan 2016 to Dec 2019 at Fuwai hospital were retrospectively analyzed.Results:There were 35 patients in the hybrid Ⅳb technique group, 93 in the chimney technique group, and 184 in the in vitro fenestration group. The follow-up period ranged from 12 to 24 months. No artificial blood vessel and stent occlusion occurred in all patients during follow-up, and the LSA blood flow was unobstructed. A total of 19 patients had endoleak by the last follow-up, and there was no statistical difference between the three groups. Eleven patients underwent reintervention surgery, all were from chimney technique group and in vitro fenestration group, with no statistical difference ( P>0.05). Severe complications occurred in 28 patients during hospitalization, and the incidence of complications was the highest in the hybrid Ⅳb technique group ( P<0.01). During follow-up, 4 patients died in the bypass group, 6 died in the external window group, and 8 died in the chimney group, with no significant difference ( P>0.05). Conclusions:The safety and efficacy of the left subclavian artery flow reconstruction by in vitro fenestration and chimney technique were similar. The occurrences of early complications were lower than that of the hybrid Ⅳb technique, but the reintervention rate of endoleak was higher.

ObjectiveTo explore the association between daily executive function and core symptoms， the symptoms of attention deficit hyperactivity disorder （ADHD） in children with autism spectrum disorder （ASD）， and the moderating effect of theory of mind and other cognitive abilities on this association. MethodsChildren aged 6-12 years with ASD were recruited， and 86 children were identified according to the inclusion and exclusion criteria. Wechsler Intelligence Test for Children， Fourth Edition （WISC-Ⅳ）， Strange Story Test （SST） and Behavior Rating Inventory of Executive Function （BRIEF） were used to evaluate children's cognitive ability. Swanson Nolan and Pelham-Version Ⅳ Scale （SNAP-Ⅳ）， Social Responsiveness Scale （SRS）， and Repetitive Behavior Scale-Revise （RBS-R） were used to assess the severity of ADHD symptoms， social impairment， and repetitive stereotyped behavior. Multiple linear regression was used to explore the association between daily executive function and ADHD symptoms， social impairment， repetitive stereotyped behaviors. ResultsAfter controlling for the score of strange stories， verbal comprehension index （VCI） and other factors， the full scale score and each index of BRIEF were positively correlated with full scale score of SNAP （b = 0.619-0.741， b’ = 0.637-0.755）， SRS （b = 0.928-1.200， b’ = 0.417-0.513） and RBS-R （b = 0.326-0.525， b’ = 0.339-0.520） in children with ASD （P< 0.05）， and the SNAP total score was more strongly correlated with the full scale BRIEF score and each index score （b’ = 0.637-0.755，P< 0.01）. In addition to daily executive function， strange stories score （b = -2.218- -1.839） and age （b = 3.181-4.037） were also the important factors affecting the social function of children with ASD （P< 0.01）. There were no moderating effects of strange stories score and age on the association between BRIEF score and full scale score of SNAP， SRS， and RBS-R（P> 0.05）. ConclusionThe deficits of daily executive function in school-aged ASD children are significantly associated with core symptoms and ADHD symptoms， and the association is independent of other cognitive domains， such as theory of mind and verbal comprehension intelligence quotient.

BACKGROUND: Clinical trial evidence is limited to identify better topical non-steroidal anti-inflammatory drugs (NSAIDs) for treating knee osteoarthritis (OA). We aimed to compare the clinical efficacy and safety of flurbiprofen cataplasms (FPC) with loxoprofen sodium cataplasms (LSC) in treating patients with knee OA. METHODS: This is an open-label, non-inferiority randomized controlled trial conducted at Peking University Shougang Hospital. Overall, 250 patients with knee OA admitted from October 2021 to April 2022 were randomly assigned to FPC and LSC treatment groups in a 1:1 ratio. Both medications were administered to patients for 28 days. The primary outcome was the change of pain measured by visual analog scale (VAS) score from baseline to day 28 (range, 0-10 points; higher score indicates worse pain; non-inferiority margin: 1 point; superiority margin: 0 point). There were four secondary outcomes, including the extent of pain relief, the change trends of VAS scores, joint function scores measured by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and adverse events. RESULTS: Among 250 randomized patients (One patient without complete baseline record in the flurbiprofen cataplasms was excluded; age, 62.8 ± 10.5 years; 61.4% [153/249] women), 234 (93.6%) finally completed the trial. In the intention-to-treat analysis, the decline of the VAS score for the 24-h most intense pain in the FPC group was non-inferior, and also superior to that in the LSC group (differences and 95% confidence interval, 0.414 (0.147-0.681); P <0.001 for non-inferiority; P = 0.001 for superiority). Similar results were observed of the VAS scores for the current pain and pain during exercise. WOMAC scores were also lower in the FPC group at week 4 (12.50 [8.00-22.50] vs . 16.00 [11.00-27.00], P = 0.010), mainly driven by the dimension of daily activity difficulty. In addition, the FPC group experienced a significantly lower incidence of adverse events (5.6% [7/124] vs . 33.6% [42/125], P <0.001), including irritation, rash and pain of the skin, and sticky hair uncovering pain. CONCLUSIONS This study suggested that FPC is superior to LSC for treating patients with knee OA in pain relief, joint function improvement, and safety profile.

Objective:To analyze the efficacy of the enhanced recovery after surgery(ERAS)approach in endometrial cancer patients treated with surgical staging and its beneficial effects on the oxidative stress response.Methods:Eight-two endometrial cancer patients treated with surgical staging at our hospital between March 2020 and March 2022 were recruited and divided into different groups using a computer-generated random number table, with 41 in the control group who were given routine intervention and 41 in the observation group receiving ERAS.Results:About perioperative performances, the oxidative stress response, inflammatory factor levels and complications were compared between the two groups.Results in the observation group, the intraoperative body surface temperature was higher than in the control group[(36.71±0.22)℃ vs.(36.20±0.21)℃, t=10.737, P=0.000], and the time from the end of surgery to first water intake[(4.41±1.30)h vs.(6.79±1.28)h, t=8.353, P=0.000], to first food intake[(7.86±1.35)h vs.(12.88±2.57)h, t=11.073, P=0.000], to first ambulation[(12.92±3.11)h vs.(24.24±5.06)h, t=12.204, P=0.000], to first flatus[(24.11±4.96)h vs.(35.13±6.20)h, t=8.887, P=0.000], to first bowel movement[(2.67±0.63)d vs.(4.03±1.15)d, t=6.641, P=0.000]and the length of hospitalization[(3.31±1.25)d vs.(5.77±1.59)d, t=7.788, P=0.000]were shorter than in the control group.On the third day after surgery, the levels of malondialdehyde[(77.96±7.62)μmol/L vs.(90.16±7.88)μmol/L, t=7.126, P=0.000], advanced oxidation protein products[(33.16±4.75)μmol/L vs.(43.55±5.37)μmol/L, t=9.280, P=0.000], CAT[(22.59±3.01)U/ml vs.(25.12±3.3)U/ml, t=3.609, P=0.000]and reactive oxygen species[(74.13±5.02)pmol/L vs.(90.33±5.89)pmol/L, t=13.404, P=0.000]in the two groups were higher than those on the day before surgery, but were lower in the observation group than in the control group at the same time points after surgery.On the 3rd day after surgery, the levels of Tumor Necrosis Factor-α, C-reactive protein and interleukin 6 in the two groups were higher than those on the day before surgery, but were lower in the observation group than in the control group at the same points after surgery(all P<0.05). In the observation group, the incidence of complications was 14.63%, lower than 39.02% in the control group( χ2=6.212, P=0.013). Conclusions:The ERAS approach can achieve significant results in endometrial cancer patients treated with surgical staging.It can not only improve perioperative performance, relieve oxidative stress and lower inflammatory factor levels, but also effectively prevent complications.
