Objective:To investigate the clinical application value of whole brain computed tomography perfusion(CTP)imaging combined with computed tomography angiography(CTA)on head and neck in treating chronic ischemic cerebrovascular disease(ICVD)by superficial temporal artery-middle cerebral artery(STA-MCA)bypass.Methods:Fifty patients with suspected chronic ICVD who admitted to Chengdu Second People's Hospital and Deyang People's Hospital(29 cases from Chengdu Second People's Hospital and 21 cases from Deyang People's Hospital)from May 2020 to October 2024 were selected.All patients underwent whole-brain CTP examination and CTA examination on head and neck before the surgery,and then,the preoperative assessment efficacy of the combination of the two examination for patients with STA-MCA surgical indication was analyzed.The changes of the CTP parameters[cerebral blood volume(CBV),cerebral blood flow(CBF),mean transit time(MTT),time to drain(TTD),and time to maximum(Tmax)]between the affected side and the healthy side before surgery,and between them after surgery,and these parameter of affected side between before and after surgery were compared respectively.The course and the anastomosis conditions of the bypass vessels were analyzed through CTA images.The CTP parameters of patients with postoperative cerebral hyperperfusion syndrome(CHS)were statistically analyzed.Then,the relationship between the changes of cerebral perfusion values on the affected side after surgery and CHS,as well as the follow-up situation,were analyzed.Results:In 50 patients with suspected chronic ICVD,34 patients with surgical indication of STA-MCA bypass were screened out by CTA combined with CTP,who existed severely narrowed or occluded blood vessels accompanied by reduced CTP,and other 16 cases who did not meet surgical indication of STA-MCA bypass were excluded.In 34 patients with chronic ICVD,the preoperative CBF value of affected side was lower than that of healthy side,and the preoperative MTT,TTD and Tmax values of affected side were all higher than those of the healthy side,and the differences were statistically significant(t=6.648,6.030,10.638,14.063,P<0.05),while there was not significant difference in CBV value between two sides(P>0.05).In the affected side,the postoperative CBF value was higher than preoperative CBF value,and the postoperative MTT,TTD and Tmax values were lower than preoperative these indicators,and the differences were statistically significant(t=8.578,7.166,11.321,11.912,P<0.05).There was no significant difference in the CBV value between before and after surgery(P>0.05).In 34 patients with chronic ICVD,there was not significant difference in CTP parameters between the affected side and the healthy side in 28 patients with chronic ICVD after 6 patients with CHS were excluded(P>0.05).The results of CTA showed that the diameter size and course of superficial temporal artery of all patients were clearly displayed,and the bypass vessels of them were unblocked,and the anastomoses of them were well developed.All 34 patients with chronic ICVD successfully completed unilateral STA-MCA bypass surgery.After the surgery,based on the clinical symptoms and the CTP reexamination results of the patients,it was determined that 6 patients(17.7%)were CHS,whose appearances were the CBF value of affected side was(60.81±5.79)ml/100(g·min),which was significantly higher than that[(53.30±5.21)ml/100(g·min)]of the healthy side.The MTT value of affected side was(2.9±0.82)s,which was significantly lower than that of the healthy side(4.2±1.1)s,and the differences were statistically significant(t=2.358,2.341,P<0.05).In the postoperative follow-up of 2 to 17 months for patients,there was not dead case,and the clinical symptoms of the most of patients were improved significantly,and there was no serious adverse events.Conclusion:Whole-brain CTP combined with CTA examination on head and neck is conducive to accurately determine the degree of vascular stenosis and cerebral perfusion before surgery,and screen patients with chronic ICVD who occurred indications of STA-MCA surgery,and can also assess the patency of bypass vessels,the recovery degree of cerebral perfusion,and the possibility of occurring CHS after surgery,which has important clinical guiding value.

Lateral organ boundaries (LOB) domain (LBD) genes encode a family of transcription factors ubiquitous in higher plants, playing crucial roles in the growth, development, and stress responses. Hippophae rhamnoides, known for its drought, cold, and saline-alkali tolerance, offers significant economic benefits and ecological values. Utilizing the whole genome data and bioinformatics approaches, this study identified and analyzed the LBD gene family in H. rhamnoides. Additionally, we examined the expression pattern of HrLBD genes by integrating the transcriptome data from male and female flower buds in development. Eleven LBD genes were identified in H. rhamnoides, and these genes were distributed on five chromosomes. The HrLBD proteins showed the lengths ranging from 159 aa to 302 aa, the molecular weights between 18 249.91 Da and 33 202.01 Da, and the subcellular localization in the nucleus or chloroplasts. LBD protein domains and gene structures were highly conserved, featuring similar motifs. The phylogenetic analysis of HrLBD genes and the LBD genes in Arabidopsis thaliana and Hordeum vulgare revealed that HrLBD genes falled into two major categories: Class Ⅰ and Class Ⅱ. The transcriptome data and RT-qPCR showed that HrLBD genes were highly expressed in male flower buds, with up-regulated expression levels throughout bud development, indicating a role in the specific stage of male flower bud development. This study lays a theoretical foundation for exploring the roles of HrLBD genes in the growth, development, and sex differentiation of H. rhamnoides flower buds.

Objective:To compare the efficacy of the Preterm Infant Oral Feeding Readiness Assessment Scale (PIOFRA) and Preterm Infant Oral Feeding Ability Readiness Assessment Scale (POFARA) in predicting the outcome of first oral feeding in preterm infants.Methods:This study was a cross-sectional study. From February 2021 to February 2022, 276 premature infants treated in the Neonatal Intensive Care Unit of the Second Affiliated Hospital of Air Force Medical University of People's Liberation Army and the Second Affiliated Hospital of Shaanxi University of Chinese Medicine were selected by convenience sampling method. According to the outcome of the first oral feeding, the premature infants were divided into a successful first oral feeding group ( n=227) and a failed first oral feeding group ( n=49). PIOFRA and POFARA were used to evaluate premature infants. The area under the receiver operating characteristic curve ( AUC), sensitivity, specificity, Youden index and other indicators were used to compare the predictive efficacy of the two scales for the first oral feeding outcome of premature infants. Results:The success rate of first oral feeding for premature infants was 82.25% (227/276). The PIOFRA and POFARA scores of the successful first oral feeding group were higher than those of the failed first oral feeding group ( P<0.01). The AUC of PIOFRA was 0.830. When the total score of PIOFRA was 27.00, the sensitivity was 78.40%, the specificity was 75.50%, and the Youden index was 0.539 ( P<0.01), and its prediction efficiency was the highest. The AUC of POFARA was 0.928. When the total score of POFARA was 33.00, the sensitivity was 79.70%, the specificity was 95.90%, and the Youden index was 0.757 ( P<0.01), and its prediction efficiency was the highest. The AUC, sensitivity, specificity and Youden index of POFARA were higher than those of PIOFRA. Conclusions:The predictive efficacy of POFARA is higher than that of PIOFRA. It is recommended to use POFARA for the evaluation and prediction of the outcome of first oral feeding in premature infants.

Objective To explore the characteristics of baseline inflammatory markers in diabetic foot patients and their relationship with the prognosis of diabetic foot ulcers.Methods The clinical data of diabetic foot patients(n=495)admitted to West China Hospital,Sichuan University since 2016 were retrospectively collected through the hospital electronic medical record system to analyze the characteristics of inflammatory markers and their relationship with the prognosis of diabetic foot ulcers.Results White blood cell count(WBC),erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),procalcitonin(PCT),and interleukin-6(IL-6)levels were significantly higher in patients defined as grade 4 on the Wagner Scale than those in patients defined as grade 0-3 on the Wagner Scale.Neutrophil percentage(NE%)was higher in Wagner grade-4 patients than those in Wagner grade-0 and grade-1 patients and higher in Wagner grade-3 patients than those in Wagner grade-0 patients.NE%,CRP,PCT,and IL-6 levels were positively correlated with the severity of diabetic foot,with the respective odds ratio(OR)at 95%confidence interval(CI)being 1.038(1.019-1.056),1.019(1.012-1.026),8.225(2.015-33.576),and 1.017(1.008-1.025).Using Wagner grade-0 patients as the reference,patients with higher WBC were more likely to progress to Wagner grade 2,3,and 4,with the respective OR(95%CI)values being 1.260(1.096-1.447),1.188(1.041-1.356),and 1.301(1.137-1.490);patients with higher ESR were more likely to progress to Wagner grade 3 and 4,with the respective OR(95%CI)values being 1.030(1.006-1.054)and 1.045(1.019-1.071).Baseline ESR(P=0.008),CRP(P=0.039),and IL-6(P=0.033)levels were lower in patients who had received antibiotics prior to their admission than those in patients who had not received antibiotics before admission.The levels of WBC,NE%,ESR,PCT,and IL-6 were lower in the full recovery group than those in the group of patients who did not respond to treatment.The higher the levels of NE%and IL-6,the worse the prognosis of diabetic foot ulcers became,with the respective OR(95%CI)values being 1.030(1.010-1.051)and 1.008(1.002-1.013).Conclusion The severity of diabetic foot ulcers increased with the rise in baseline levels of inflammatory markers.Elevated baseline NE%and IL-6 levels suggest a poor prognosis.Our findings suggest that early assessment of diabetic foot infection and standardized antibiotic therapy should be implemented to improve the prognosis.
