ABSTRACT
Professor ZHANG Boli believed that the core pathogenesis of heart failure with preserved ejection fraction （HFpEF） is weak pulse at yang and wiry pulse at yin. By referring to the theory of “damp-turbidity and phlegm-rheum type of diseases”， he proposed that yin pathogens of damp-turbidity and phlegm-rheum may damage yang qi in each stage of HFpEF， thus aggravating the trend of weak pulse at yang and wiry pulse at yin， which played an important role in the deterioration of HFpEF. Therefore， Professor ZHANG Boli advocated that importance should be attached to the elimination of yin pathogen and the protection of yang qi during the various stages of HFpEF in order to delay the aggravation of weak pulse at yang and wiry pulse at yin； he put forward the idea of staged treatment that “yin pathogen should be dispelled and yang qi should be demonstrated”； and he formulated the treatment strategy of treating the disease as early as possible， eliminating pathogens and protecting yang， interrupting the disease trend， using warm-like medicinals， and activating blood circulation， to enrich the theoretical system of traditional Chinese medicine in the treatment of HFpEF.
ABSTRACT
This article summarizes the experience of Professor ZHANG Boli in the staged treatment of very early onset inflammatory bowel disease （VEO-IBD）. Grounded in the theory of “similar diseases and syndromes of damp-turbidity-phlegm-rheum”， it is believed that dampness and turbidity are crucial pathogenic factors in VEO-IBD. During the acute phase， the core pathogenesis centers on the accumulation of turbid toxins in the intestines. The treatment focuses on dispelling dampness and clearing turbidity to eliminate turbid toxins， while also regulating the flow of qi and nourishing the spleen and kidney. During the remission phase， the core pathogenesis involves spleen and kidney deficiency， which is treated by invigorating the spleen and warming the kidney to strengthen the body resistance. Additionally， promoting blood circulation and eliminating stasis is integrated throughout the treatment process. Medications are chosen to be mild and gentle， emphasizing balance and harmony， and attention is given to the methods of administration and psychological well-being， ensuring comprehensive care for both body and mind.
ABSTRACT
Objective:To explore the safety and feasibility of the simultaneous combined operation in children with congenital heart disease complicated with non-cardiac malformation.Methods:A total of 72 children undergoing combined surgery or simple heart surgery in the Department of Cardiac Surgery, Children′s Hospital, Capital Institute of Pediatrics from January 2017 to January 2019 were enrolled.According to the severity of the disease, patients in the combined operation group (group A) and the simple heart surgery group (group B) were separately subdivided into the low risk group (group L) and the high risk group (group H). There were 36 children in group A, with the age ranging from 1.5 to 168.0 months old (median: 18.0 months). There were 36 cases in group B, with the age ranging from 1.0 to 170.0 months old (median: 19.0 months). Patients in groups A and B were sent to the cardiac intensive care unit(ICU) after operation.The cardiopulmonary bypass (CPB) time, aortic clamping (ACC) time, tracheal intubation time, intensive care unit (ICU) retention time, brain natriuretic peptide (BNP), alanine aminotransferase (ALT) and creatinine (Cr) were recorded.Besides, the cardiac output index (CI), cardiac circulation efficiency (CCE), maximum pressure gradient (dp/dt), lactic acid (Lac), blood glucose (Glu), inotropic score (IS) were also recorded at the time of returning to ICU (T0), 4 hours after operation (T1), 8 hours after operation (T2), 12 hours after operation (T3), 24 hours after operation (T4) and 48 hours after operation (T5), respectively.Results:(1) Intra-group comparison in group A: the age [(39.9±37.0) months], height [(94.1±20.1) cm] and weight [(14.4±6.7) kg] of children at low risk (group L-A) were significantly higher than those at high risk (group H-A) [(7.5±3.7) months, (68.1±6.4) cm, (7.8±2.2) kg] (all P<0.01). The CPB time [(37.0±23.6) min], ACC time [(19.1±13.4) min], endotracheal intubation time [(7.1±4.7) h], ICU retention time [(1.1±0.3) d] and BNP 24 hours after operation [(2 257.3±952.0) ng/L] in group L-A were significantly lower than those in group H-A [(84.7±28.4) min, (41.9±30.7) min, (71.0±67.6) h, (8.7±5.7) d and (5 327.2±992.9) ng/L] (all P<0.01). Glu, IS, CI, CCE were significantly different between patients at low risk and patients at high risk ( P<0.05). At the time of T0-T5, the Glu( F=4.43, P<0.05) and IS ( F=26.99, P<0.01)of group L-A were lower than those of group H-A, and the CI ( F=18.39, P<0.01)and CCE ( F=5.28, P<0.05) of group L-A were higher than those of group H-A.(2) Comparison between groups A and B: there was no significant difference in age, height, weight, CPB time, ACC time, hemodynamic parameters, arterial blood gas parameters and postoperative clinical indexes between patients at high risk or patients at low risk in group A and group B (all P>0.05). Conclusions:(1) For the patients at low risk, hemodynamics remains stable after the combined operation.The combined operation does not increase the endotracheal intubation time and ICU retention time, so it is safe and feasible.(2) For the patients at high risk, hemodynamics is also stable after the combined operation.However, their IS is higher than that of patients at low risk at any time point, and the incidence of postoperative adverse events is higher than that of patients at low risk.It is necessary to evaluate the condition and operation plan of the children before operation.
ABSTRACT
Objective:To explore the tricuspid annular plane systolic excusion(TAPSE) in children with left-to-right shunt after congenital heart disease surgery and to understand the early systolic function of right heart in thesepatient.Methods:From June 2018 to December 2018, a prospective study was conducted in 20 infants after repair of left-to-right shunt congenital heart disease, including 10 males(50%) and 10 females(50%) , aged from 1 to 12 months, with a median of 4.5(2.0, 6.8) months, a body mass of 3.0-9.0 kg with median of 6.0(3.7, 7.7) kg.On the first postoperative day, blood was taken from central venous for N-terminal pro-B-type natriuretic peptide(NT pro-BNP) test, TAPSE and left ventricular ejective fraction(LVEF) was measured by echocardiography.The effects of aortic occlusion time, cardiopulmonary bypass time, preoperative pneumonia and preoperative heart failure on TAPSE were compared. The relationship between TAPSE and heart rate, systolic pressure, central venous pressure, vasoactive drug score, endotracheal intubation time, detention time in intensive care unit, NT pro-BNP and LVEF after operation was analysed.Results:The aortic cross-clamping time was 15-87 minutes, with median 31(28, 50) minutes. The cardiopulmonary bypass time was 35-117 minutes, with an average of(68±22)minutes. The time of tracheal intubation was 4-117 hours, with an average of(50±35) hours. The stay time in CICU was 1-14 days, with a median of 5(2, 7) days.The LVEF was 0.18-0.66, with median 0.53(0.42, 0.57). The TAPSE was 2.0-10.0 mm, with an average of(5.2±2.0) mm. On the first day after operation, NT pro-BNP was 1 548-35 000 pg/ml, with an average of(9 446±8 130) pg/ml.TAPSE was negatively correlated with postoperative intubation time( r=-0.576, P= 0.007) and detention time in ICU( r=-0.765, P=0.000), and positively correlated with postoperative LVEF( r=0.461, P=0.041)( P<0.05). TAPSE was negatively correlated with heart rate( r=-0.303, P=0.193), central venous pressure( r=-0.425, P=0.062), vasoactive drug score( r=-0.418, P=0.067) and NT Pro BNP( r=-0.348, P=0.132), and positively correlated with systolic pressure( r=0.146, P=0.54), but there was no statistical significance in each item.Compared with patients with TAPSE≥5mm, the detention time and tracheal intubation time were longer than those TAPSE<5 mm, the central venous pressure and NT-pro BNP was higher than those TAPSE<5 mm( P<0.05), the difference was statistically significant, other indicators had no significant difference. Conclusion:It is simple and feasible to measure TAPSE by echocardiography in children after operation with left-to-right shunt congenital heart disease.TAPSE decreased postoperatively suggested that the function of right ventricle decreased at the early stage after surgery, and with left ventricle systolic function decreased, which eventually led to the increase of NT pro-BNP, the need for higher doses of vasoactive drug support, longer tracheal intubation time and the stay time in CICU.Attention should be paid to the right heart function of children after congenital heart surgery.
