Objective To investigate the effect of radial artery calcification (RAC) on survival of arteriovenous fistula (AVF) and the patients in end?stage renal disease. Methods Adult ESRD patients undergoing AVF surgery between January 2013 and January 2016 at the Eighth Affiliated Hospital of Sun Yat?sen University were enrolled in this study. The clinical and biochemical data were collected. Segment of radial artery were obtained from the operation of AVF. RAC at the site of anastomotic were observed by alizarin red S and hematoxylin and eosin staining. According to RAC, the patients were divided into calcification group and non?calcification group. Kaplan?Meier analysis was performed to analyze the survival rates of the two groups, and Cox proportional hazards regression——model was used to estimate the risk factors of AVF dysfunction and all?cause mortality in ESRD patients. Results Among 180 cases of ESRD patients, 38 cases (21.1％) were developed RAC at the site of anastomotic in different degrees. Compared with the non?calcification groups, the calcification groups had a longer dialysis vintage, a higher proportion of diabetes and higher level of HbAlc (all P﹤0.05). Binary logistic regression analysis showed that dialysis vintage>5 years and diabetics were two independent risk factors of RAC at the site of anastomotic. Kaplan?Meier survival analysis demonstrated that there were no statistical differences between two groups in AVF survival (χ2=0.009, P=0.926). Calcification group had higher all?cause mortality than non?calcification groups (χ2=9.809, P=0.002). Multivariate Cox regression analysis demonstrated that homocysteine was independent risk factor for AVF dysfunction (HR=1.027, 95％CI: 1.003-1.051, P=0.027). Age was independent risk factor for all?cause mortality (HR=1.078, 95％CI: 1.035-1.122, P=0.000). Conclusions Dialysis vintage>5 years and diabetes were two independent risk factors of RAC at the site of anastomotic in ESRD patients. RAC at the site of anastomotic had no effect on AVF survival, but increased all?cause mortality.

Objective:To evaluate the safety and efficacy of the neoadventitia technique for root repair in acute type A aortic dissection(ATAAD).Methods:From January 2019 to February 2022, a total of 94 patients with ATAAD who underwent surgical treatment in Beijing Anzhen Hospital were retrospectively analyzed. According to the different treatment methods for the aortic root, the patients were divided into the neoadventitia technique group(58 cases) and the Bentall group(36 cases). The perioperative data and postoperative follow-up results of the two groups were compared, and the efficacy of the new adventitia technique in acute type A aortic dissection was analyzed.Results:There were no intraoperative deaths. The 30-day mortality was 3.4% and 5.6% in the neoadventitia group and Bentall group, respectively ( P=0.636). The cardiopulmonary bypass time[(154.3±29.8)min, P<0.001] and aortic clamp time[(94.7±20.6)min, P<0.001)]were significantly shorter in the neoadventitia group, compared with the Bentall group. Aortic regurgitation was significantly improved after the operation (0.33±0.50 vs. 1.02±0.80, P<0.001). No aortic root-related secondary intervention occurred during follow-up. There was no significant difference in mortality between the two groups( P=0.248). Conclusion:Neoadventitia root repair is a safe and feasible method for the treatment of ATAAD, which has good short-term and mid-term efficacy.

Objective:To evaluate the efficacy of new arch-clamping technique in Sun’s procedure to repair acute type A aortic dissection.Methods:67 consecutive patients with acute type A aortic dissection who underwent total arch replacement and frozen elephant trunk implantation(TAR+ FET) from Dec 2019 to Dec 2022 with using new arch-clamping technique during operation. Relative intraoperative and postoperative variables and complications were compared.Results:Cardiopulmonary bypass time was(166.66±32.81)min, the aortic occlusion time was(100.49±19.96)min, the circulatory arrest time was(3.97±1.63)min, the lowest nasopharyngeal temperature was(25.716±1.304)℃, and the lowest bladder temperature was(26.209±1.552)℃. The whole group died in hospital in 2 cases(2.98%), cerebral infarction in 3 cases(4.48%), transient neurological dysfunction in 4 cases(5.97%), paraplegia patients in 1 case(1.49%), renal failure requiring continuous dialysis in 4 cases(5.97%).Conclusion:New arch-clamping technique decrease postoperative complication, and is a safe and feasible innovative approach to effectively improve surgical outcome of Sun’s procedure for repair of acute type A aortic dissection.

Objective:To establish the biology reference interval (RI) of peripheral blood procalcitonin (PCT) for children between 3 days and 6 years old in China.Methods:Totally 3 353 reference individuals with apparent health or no specific diseases were recruited in 18 hospitals throughout the country during October 2020 to May 2021. Reference individuals were divided into four groups: 3-28 days, 29 days - 1 year, 1-3 years and 4-6 years. Vein blood or capillary blood were collected by percutaneous puncture from every reference individual. The PCT level in serum and the capillary whole blood were assayed by Roche Cobas e601 and Norman NRM411-S7 immunoanalyzer. Outliers were deleted and 95th percentiles of every group were provided as RIs. Man-Whitney U test or Kruskal-Wallis test were used performed to assess the difference among different gender, age or method groups. Results:The difference of PCT distribution between male and female is not statistically significant, but the difference between serum and capillary whole blood is statistically significant. The differences between age groups are significant too. For Roche e601, serum PCT RI of 3-28 days group is <0.23 μg/L, 29 days - 6 years are <0.11 μg/L. For NRM411, Serum PCT RI of 3-28 days group is <0.21 μg/L, 29 days - 1 year: <0.09 μg/L, 1 - 6 years: <0.10 μg/L. For whole blood PCT, RI of 3-28 days group is <0.26 μg/L, 29 days - 6 years is <0.15 μg/L.Conclusions:Serum and capillary whole blood PCT have different RIs, however, capillary whole blood PCT testing is valuable in pediatric application. Children in 3-28 days show higher PCT levels than other age group. To establish the RIs and understand the differences among different groups are essential for the interpretation and clinical application of peripheral blood PCT testing results.
