Objective To explore growth pattern of neo-aortic root as well as development of neo-aortic regurgitation after arterial switch operation (ASO) for Taussig-Bing anomaly. Methods From 2002 to 2017, the patients who received ASO, and were discharged alive from Shanghai Children’s Medical Center and followed up for more than 3 years were retrospectively involved in this study. Results A total of 127 patients were enrolled. There were 98 (77.2%) males, the median age at ASO was 73.0 d and the average weight was 4.7 kg. Forty-five (35.4%) children were complicated with mild or mild-to-moderate pulmonary insufficiency (PI) before ASO. The average follow-up time was 7.0 years. During the follow-up, 14 (11.0%) children presented moderate or greater neo-aortic regurgitation (neo-AR). The diameter of neo-aortic annulus and sinus of Valsalva was beyond normal range during the entire follow-up. The average diameter of neo-aortic annulus was 18.0 mm at 5 years and 20.5 mm at 10 years. The average diameter of sinus of Valsalva was 25.9 mm at 5 years and 31.1 mm at 10 years. Neo-AR continued to develop over time. The diameter of children who developed moderate or greater neo-AR was constantly larger than that of children who did not (χ2=18.3, P<0.001). Preoperative mild or mild-to-moderate PI was an independent risk factor for the development of moderate or greater neo-AR during mid-to-long term follow-up (c-HR=3.46, P=0.03). Conclusion The diameters of neo-aortic annulus and sinus of Valsalva of Taussig-Bing children who receive ASO repair continue to expand without normalization. The dilation of annulus correlates with the development of neo-AR. PI before ASO repair increases the risk of neo-AR development.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Objective    To explore the effect of LeCompte maneuver on in-hospital mortality and mid-to-long term reintervention after single-stage arterial switch operation in children with side-by-side Taussig-Bing anomaly. Methods     Clinical data of patients diagnosed with side-by-side Taussig-Bing anomaly and undergoing single-stage arterial switch operation in Shanghai Children’s Medical Center from 2006 to 2017 were retrospectively analyzed. Patients were divided into two groups based on whether LeCompte maneuver was performed: a LeCompte maneuver group and a non LeCompte maneuver group. The clinical data of two groups were compared. Results    Finally 92 patients were collected. LeCompte maneuver was performed in 32 out of 92 patients with a median age of 65.0 days and an average weight of 4.3 kg, among whom 24 (75.0%) were male. Fifteen (46.9%) patients received concomitant aortic arch repair while 12 (37.5%) patients were associated with coronary artery malformation. LeCompte maneuver was not performed in 60 patients with a median age of 81.0 days and an average weight of 4.8 kg, among whom 45 (75.0%) were male. Twenty-two (36.7%) patients received concomitant aortic arch repair while 35 (58.3%) patients were associated with coronary artery malformation. The average cardiopulmonary bypass duration of the LeCompte maneuver group showed no statistical difference from the non LeCompte maneuver group (179.0±60.0 min vs. 203.0±74.0 min, P=0.093). The in-hospital mortality of the two groups were 6 (18.8%) and 7 (11.7%), respectively, which also showed no statistical difference (P=0.364). The median follow-up period was 4.1 (1.6, 7.5) years for 79 patients with 8 lost to follow-up, and no death was observed. Kaplan-Meier curve and log-rank test showed no statistical difference in overall mid-to-long term reintervention rate (P=0.850) as well as right ventricular outflow tract and pulmonary artery reintervention rate (P=0.240) with or without LeCompte maneuver. Conclusion    Whether or not to perform LeCompte maneuver shows no statistical impact on in-hospital mortality and mid-to-long term reintervention rate of single-stage arterial switch operation for side-by-side Taussig-Bing anomaly.

The central circadian clock and feeding rhythm coordinately reset peripheral circadian clocks. Emerging evidence suggests that feeding rhythm resets peripheral circadian clocks in a tissue-specific manner. This study aimed to determine whether and how feeding rhythm regulates circadian rhythms of the circadian clock and metabolic genes in brown adipose tissue (BAT). We applied different regimens of time-restricted feeding (TRF) in wildtype and Per1/2 deficient C57BL/6 mice, and quantified the effects of sex, treatment duration, constant light, and circadian clock on circadian rhythms of the BAT circadian clock and metabolic genes by RT-qPCR; Representative circadian clock genes are Bmal1, Nr1d1, Dbp, and Per2, and representative metabolic genes are uncoupling protein 1 (Ucp1), 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (Pfkfb3) that controls the flux through glycolysis, pyruvate dehydrogenase kinase isozyme 4 (Pdk4) gating the tricarboxylic acid cycle, and carnitine palmitoyltransferase 1A (Cpt1a) that controls mitochondrial fatty acid oxidation. The results showed that, daytime-restricted feeding (DRF) moderately shifted the phase of the BAT circadian clock in female mice within 7 or 36 d, and resulted in the loss of circadian rhythm in Dbp and Per2 transcripts in males. DRF induced de novo oscillation of the Ucp1 transcript, and shifted the phase of representative metabolic genes, such as Pfkfb3, Pdk4, and Cpt1a, more than 7 h. Constant light is known to disrupt the synchrony of the central circadian clock. The results showed that constant light promoted phase entrainment of the circadian clock by DRF in BAT, but abolished the oscillation of the metabolic genes (except for Pdk4). Despite combined treatment with Per1/2 deficiency and constant darkness, DRF was sufficient to drive circadian rhythms of Bmal1 and Dbp, but not those of Nr1d1, Ucp1, Pfkfb3, and Cpt1a. Overall, the circadian clock of BAT has weak adaptation to altered feeding rhythms and sex differences. The central circadian clock antagonizes DRF in the entrainment of the BAT circadian clock, whereas DRF resets circadian rhythms of metabolic genes, such as Ucp1, Pfkfb3, and Cpt1a, in a circadian clock-dependent manner.

Objective: To estimate the incidence of HIV-1 infection in men who have sex with men (MSM) in key areas of China through HIV-1 limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA), analyze the deviation from the actual results and identify influencing factors, and provided reference for improving the accuracy of estimation results. Methods: Based on the principle of the cohort randomized study design, 20 cities were selected in China based on population size and the number of HIV-positive MSM. The sample size was estimated to be 700 according to the HIV-1 infection rate in MSM. MSM mobile phone app. was used to establish a detection appointment and questionnaire system, and the baseline cross-sectional survey was conducted from April to November 2019. LAg-Avidity EIA was used to identify the recent infected samples. The incidence of HIV-1 infection was calculated and then adjusted based on the estimation formula designed by WHO. The influencing factors were identified by analyzing the sample collection and detection processes. Results: Among the 10 650 blood samples from the participants, 799 were HIV-positive in initial screening, in which 198 samples (24.78%) missed during confirmation test. Only 621 samples were received by the laboratory. After excluding misreported samples, 520 samples were qualified for testing. A total of 155 samples were eventually determined as recent infection through LAg-Avidity EIA; Based on the estimation formula , the incidence of HIV-1 infection in MSM in 20 cities was 4.06% (95%CI:3.27%-4.85%), it increased to 5.53% (95%CI: 4.45%-6.60%)after the adjusting for sample missing rate. When the sample missing rate and misreporting rate were both adjusted, the incidence of HIV-1 infection in the MSM increased to 5.66% (95%CI:4.67%-6.65%). The actual incidence of HIV-1 infection in MSM in the 20 cities might be between 4.06% and 5.66%. Conclusions: Sample missing and misreporting might cause the deviation of the estimation of HIV-1 infection incidence. It is important to ensure the sample source and the quality of sample collection and detection to reduce the deviation in the estimation of HIV-1 infection incidence.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.
