The brain-gut interaction theory is a multidimensional integrative concept based on the brain-gut axis， involving neural， endocrine， and immune regulatory networks as well as the gut microbiota. Zang-fu organs （脏腑） theory in traditional Chinese medicine （TCM） shows a high degree of consistency with the brain-gut interaction theory， and the core functions such as the spleen and stomach governing the ascending of the clear and descending of the turbid， the liver governing the free flow of qi， and the heart governing mental and emotional activities are closely associated with the multi-level regulatory mechanisms of the brain-gut axis. TCM therapy can modulate brain-gut interactions through multiple pathways in the treatment of spleen and stomach diseases， including the regulation of gastrointestinal hormone secretion， neurotransmitter levels， the hypothalamic-pituitary-adrenal （HPA） axis， immune homeostasis and inflammatory responses， as well as the gut microecology. However， current basic research on the brain-gut interaction theory in TCM for spleen and stomach diseases still faces several challenges， such as difficulties in integrating TCM spleen-stomach theory with modern pathophysiology， lack of innovation in research concepts， and limitations in research methodologies. It is therefore proposed that multidisciplinary collaboration， multi-omics technologies， and targeted research approaches should be adopted to provide more comprehensive methods for basic research on TCM spleen and stomach diseases， thereby promoting the in-depth development of brain-gut interaction theory.

Objective:To investigate the characteristics of congenital hypothyroidism (CH) in premature infants and analyze the predictors of transient congenital hypothyroidism(TCH) and permanent CH (PCH).Methods:A retrospective study was conducted on the preterm infants with CH born in Beijing from January 2008 to June 2018. They were screened, diagnosed and treated by the Beijing Neonatal Disease Screening Center. They were assigned into TCH and PCH groups according to the clinical prognosis. Univariate analysis and Logistic regression analyses were used to determine the predictors of PCH, and the receiver operating characteristic curve (ROC) was drawn to determine the best cut-off point.Results:A total of 2 216 892 newborns were screened, 15 382 were initially screened positive, the median time of screening was 4(4,10) d after birth, and the median time of postnatal reexamination was 30(22,42) d after birth, 14 576 newborns were reexamined, the reexamination rate was 94.8%. A total of 92 preterm infants were diagnosed with CH, of which 60 were TCH, accounting for 65.2%; 28 were PCH, accounting for 30.4%; and 4 were lost to follow-up, accounting for 4.3%. Univariate analysis showed that in the PCH group, the abnormal rate of thyroid B-ultrasound, levothyroxine (LT4) dose at 1-year old, thyrotropin (TSH) level at 2 years old, LT4 dose at 2 years old, LT4 dose and free thyroxine (FT4) level at 3 years old were higher than those in the TCH group. Logistic regression analysis revealed that abnormal B-ultrasound ( OR=12.184,95% CI 2.270~65.403), and elevated TSH level at 2 years old ( OR=2.033,95% CI 1.280~3.228),increased LT4 dose at 3 year old ( OR=21.435,95% CI 3.439~133.584) are the risk factors for PCH. The maximum area under ROC curve was 0.798 at 3 years old (95% CI 0.680~0.916), the best cut-off point was 1.3 μg/(kg·d) for the 3-year-old drug dose; followed by 2-year-old TSH level, which was 0.683 (95% CI 0.548~0.817), the best cut-off point was 4.51 μIU/ml. Conclusions:TCH accounted for a large proportion of preterm infants with CH. During the follow-up, the increased LT4 dose at 3 years old and the elevated TSH level at 2 years old were the early predictors of PCH.

Objective: To explore the relationship between intra-operative blood product transfusion and post-operative prognosis in children with pediatric open heart surgery by cardiopulmonary bypass (CPB).
Methods: A total of 1028 consecutive pediatric patients received the open heart surgery by CPB in our hospital were retrospectively studied. Uni- and multivariate Logistic regression analysis were conducted to analyze the relationship between intra-operative blood product transfusion and post-operative in-hospital death and complication rates.
Results: There were 45/1028 (4.4%) of patients died, 143 (13.9%) with low cardiac output syndrome, 43 (4.2%) received dialysis, 26 (2.5%) with sustained pulmonary failure, 17 (1.7%) with infection, and 28 (2.7%) developed neurologic complications. Multivariate Logistic regression analysis indicated that duration and the lowest temperature of CPB, 24-hour post-operative pediatric risk of mortality (PRISM-III) score and intra-operative transfusion amount of RBC > median (20.3 ml/kg) were the independent risk factors for post-operative in-hospital death. Congenital heart disease (CHD) with pre-operative cyanosis, duration of CPB, 24-hour post-operative PRISM-III score, 6-hour post-operative mediastinal drain loss and intra-operative transfusion amount of RBC > 20.3 ml/kg were the independent risk factors for post-operative complication occurrence.
Conclusion: Large volume of RBC transfusion in the open heart pediatric surgery with CPB may increase the risk of post-operative in-hospital death and complication occurrence, reducing RBC transfusion might be improving the post-operative prognosis in CHD patients.

Objective To conduct a screening survey of glycophorin (GP) variants and observe the content changes of sialic acid (SA) and total sulfhydryl (SH) groups on the erythrocyte membranes among residents in a tertian malaria hyperendemic area of Guizhou Province.Methods GP variants were detected in the erythrocyte hemolysates of 173 local residents at two villages of Libo County by SDS-PAGE on 10% to 15% gradients gel and Western immunoblotting. Their SA and total SH group contents were estimated in erythrocyte membranes by spectrophotometric methods. 114 healthy subjects in Changsha and 49 individuals at a neighbouring village of the above area showing low morbidity of malaria served as normal and endemic controls respectively.Results Three distinct types of GP variants were found among 19 propositi in this hyperendemic area. The incidence of GP variants was 7.9% (8/101) at Yaolu Village whose population was mainly composed of Yao ethnic group;while that of Buyi ethnic group at Maolan Village was higher (15.3%; 11/72).The erythrocyte membrane contents of SA in residents at both villages exhibited a very significant tendency of decline (P<0.01), whereas those of total SH groups increased prominently in residents of Yaolu Village only (P<0.05).Conclusions The frequency of GP variants in this hyperendemic area does not depend upon the severity of malarial prevalence. The evident reduction of SA contents in the residents may be related to the breaking down of the SA residues on membrane GPs by the invasion of Plasmodium vivax.
