Objective:To explore the application value of artificial intelligence (AI) in image post-processing of reconstructed CTA based on CT cerebral perfusion (CTP).Methods:Clinical and radiological data of 100 patients suspected of cerebrovascular diseases in Hebei General Hospital from January to July 2020 were retrospectively selected. All patients were divided into A and B group on average according to the different examination schemes. Cerebral CTP examination was performed in group A (the temporal maximum intensity projective data set generated by the first 5 time phases in the maximum period of the difference between arteriovenous CT values selected as subgroup A1, and the corresponding original thin-layer images selected as subgroup A2), single phase CTA examination was performed in group B, manual and AI image post-processing were performed respectively. Subjective scoring of the image data was performed, and the objective bid evaluation indexes such as CT value, noise (SD), signal-to-noise ratio (SNR), contrast to noise ratio (CNR) were measured, the qualified rate of artificial and AI vascular segmentation was counted, and post-processing time were recorded. The objective evaluation indexes were compared between three groups using one-way ANOVA, and the Kruskal-Wallis H test was used to compare the difference of subjective scores.Results:Statistically significant differences were observed in subjective score and objective evaluation index of original images among group A1, group A2 and group B (all P<0.05). Among them, arterial enhancement, arteriolar detail display score, cerebral artery CT value, SNR and CNR in group A1 were higher than those in group A2 and group B (all P<0.05). In a total of 100 patients with 1 100 blood vessels, the qualified rates of AI vascular segmentation in group A1 [98.4% (541/550)] and group B [98.7% (543/550)] were higher than those of manual [82.9% (456/550), 87.1% (479/550), χ2=77.392, 56.521, P<0.001], but the qualified rate of AI vascular segmentation of group A2 [78.4% (431/550)] was lower than that of manual [85.6% (471/550), χ2=9.855, P=0.002]. The completion time of AI post-processing were reduced by 56.30%, 49.63%, 50.81%, respectively than those with manual. Conclusion:Compared with manual image post-processing, AI has certain advantages in image quality and work efficiency of reconstructed CTA post-processing based on CTP de-noising dataset, and it is worth popularizing and applying in the image post-processing of cerebrovascular disease, combined with artificial quality control.

Objective The author seeked the suitable tidal volume in order to decrease mechanical ventilation-induced lung injury during closed circuit anesthesia in infants.Methodes 50 infants who practiced selective orthopedics operation randomly divided into traditional mode(12~15ml/kg,groupT,n=25)and low tidal volumes(7~8ml/kg,groupL,n=25).The bronchoalveolar lavage fluid of intants were collected immediately after tracheal intubation(T1)and before tracheal extubation,respectively.Interleukin-6 and interleukin-8 in the bronchoalveolar lavage fluid were determined by enhancement solid-phase enzyme immunoassay action(EASIA),TNF-? in the bronchoalveolar lavage fluid were determined by euzymelinked immunosorbent assay(EIA).The numbers of polymorphonuclear neutrophils in the bronchoalveolar lavage fluid of intants were examined.The infants' SpO2,arterial blood pressure and PetCO2 were monitored continuously.Arterial blood gas was analysised.The time of analepsia and complications of lung were observed after operation.Results PaCO2、PetCO2 in groupL were higher than that in groupT,pH in groupL lower than that in groupT at 30 min,60 min,120 min after mechanical ventilation and before extubation,respectively.The contents of PMN,TNF-?,IL-6 and IL-8 in BALF collected at T2 more than that at T1 in groupT.The contents of PMN,TNF-?,IL-6 and IL-8 in BALF in groupL less than that in groupT at T2(P

Objective To investigate the effect of ambroxol administered before surgery on contents of PMN,TNF-?,IL-6 and IL-8 in bronchoalveolar lavage fluid after closed circuit anesthesia in infants.Methods 40 infants who practiced selective orthopedics or abdominal operations were randomly divided into ambroxol group (group A) and control group (group B). Two days before operation,infants in group A and group B were administed ambroxol 0.3 mg/kg or 0.9 normal saline 10 ml through intravenous injection three times per day,respectively .The last single dose was administered before anesthesia induction.The bronchoalveolar lavage fluid of intants were collected immediately after tracheal intubation(T1) and before tracheal extubation(T2),respectively.Interleukin-6 and interleukin-8 in the bronchoalveolar lavage fluid were determined by enhancement solid-phase enzyme immunoassay action(EASIA),and TNF-? in the bronchoalveolar lavage fluid by euzymelinked immunosorbent assay (EIA).The numbers of polymorphonuclear neutrophils in the bronchoalveolar lavage fluid were examined. The contents of PMN,TNF-?,IL-6 and IL-8 in two groups were compared .The time of analepsia and complications of respiratory tract were observed after operation.Results Compared with group A, the contents of PMN,TNF-?,IL-6 and IL-8 in BALF collected at T2 were significant higher in group B (P
