摘要:目的:分析高膽紅素血癥新生兒血清神經元特異性烯醇化酶(NSE)含量和新生兒行為神經能力測評(Neonatal Behavioral Neurological Assessment,NBNA)的變化,探討高膽紅素血癥新生兒血清NSE含量變化的臨床意義。方法:應用放射免疫分析法分別測定60例高膽紅素血癥新生兒和20例對照組新生兒血清NSE含量,同步測定血清總膽紅素(TSB),進行NBNA評分;高膽紅素血癥組早期干預后再次測定血清NSE含量。結果: 與對照組比較,高膽紅素血癥新生兒血清TSB、NSE含量顯著升高,而NBNA評分明顯降低,差異有顯著性意義(Plt;0.01);對照組與高膽紅素血癥新生兒輕度增高、中度增高、重度增高四組兩兩比較(均Plt;0.05),存在顯著性差異;血清NSE含量與NBNA評分呈明顯負相關(r=-0628,Plt;0.01);高膽紅素血癥新生兒經早期干預治療后,血清NSE含量均下降(Plt;0.05),差異有顯著性。結論: 高膽紅素血癥可導致新生兒腦損傷,血清NSE含量可以作為腦損傷的監測指標。Abstract: Objective: To analyze levels of neuronspecific enolase(NSE)in serum and neonatal behavioral neurological assessment (NBNA), to study whether NSE in serum can be used as a tool for the early identification of brain damage in neonatal hyperbilirubinemia. Methods: Serum NSE level of 60 full term infants with hyperbilirubinemia and 20 cases as to control group were measured by radioimmunoassay; Also total serum bilirubin (TSB) and NBNA were detected. In the hyperbilirubinemia group,serum NSE level were measured second when TSB were less than 855 μmol/L(5 mg/dL). Results: Compared with control group,the levels of serum TSB、NSE of the hyperbilirubinemia group were significantly higher, but NBNA score was significantly lower. The levels of serum NSE was significantly negative related to NBNA score. In the hyperbilirubinemia group, serum NSE level were significantly lower after treatment. Conclusion: Hyperbilirubinemia in neonates can cause brain damage. Serum NSE level could work as monitoring indexes of this damage.
Objective To explore the feasibility and option of different surgeries for neonates with pulmonary atresia and ventricular septal defect (PA/VSD) through assessing the effect of common surgeries. Methods Fourteen neonates who underwent their first surgery in our center from July 2004 to October 2014 were included. Their basic characteristics, operation and pre- and postoperative clinical information were extracted. Follow up was conducted and the last visit was on October 10, 2016. Short- and midterm survival and total correction rate were compared among different surgeries. Results Among the 14 patients, there were 4 (28.6%) patients, 6 (42.9%) and 4 (28.6%) who underwent one-stage repair, right ventricular outflow tract (RVOT) reconstruction, and systemic to PA shunt operation respectively. The overall in-hospital mortality after the first operation was 28.6% (4/14). At last visit, no death occurred resulting the 5-year survival rate of 71.4% (10/14). The overall total correction rate for all neonates was 64.3% (9/14). Although no statistical difference was found in the mortality among the one-stage repair , RVOT reconstruction and systemic to PA shunt group(50.0% vs. 33.3% vs. 0.0%, P=0.280), the survival and hazard analysis implied better outcomes of the systemic to PA shunt palliation operation. There was no statistical difference in the total correction rate and months from the first palliative operation to correction between those who underwent RVOT reconstruction and systemic to PA shunt (75.0% vs. 50.0%, P=0.470; 32.0 months vs. 18.0 months, P=0.400). Conclusion Performing surgeries for neonates with PA/VSD is still a great challenge. However, the midterm survival rate was optimistic for the early survivors. Systematic to PA shunt seemed to be a better choice with lower mortality for the neonates with PA/VSD who need the surgery to survive.
Objective To analyze the use of modified pericardial oblique sinus approach in surgical repair for total anomalous pulmonary venous connection in neonates. Methods Between May 2005 and December 2015, 67 consecutive neonates with supracardiac or infracardiac type total anomalous pulmonary venous connection who underwent surgical repair in our institute were included in this study. The patients are divided into three groups according to the different approaches including a sulcus approach group (6 patients), a superior approach group (14 patients), and a modified pericardial oblique sinus approach group (47 patients). There were 53 males and 14 females at median age of 12.5 (7.0, 20.5) d. Results The time of cardiopulmonary bypass [88 (80.0, 107.0) min vs. 135 (121.0, 157.0) min, P<0.05] and aortic cross clamping of the modified pericardial oblique sinus approach group was significantly shorter than that of the sulcus approach group [45 (39.0, 53.0) min vs. 80 (73.0, 85.0) min, P<0.05]. Perioperative mortality (2.1% vs. 28.6%, P<0.05) was significantly lower in the modified pericardial oblique sinus approach group than that in the superior approach group. The long-term mortality (4.3% vs. 60.0%, P<0.05) was significantly lower in the modified pericardial oblique sinus approach group than that in the sulcus approach group or the superior approach group . The rate of pulmonary venous stenosis was significantly lower in the modified pericardial oblique sinus approach group than that in the sulcus approach group (2.1% vs. 50.0%, P<0.05) or superior approach group (2.1% vs. 35.7%, P<0.05). Conclusions In surgical correction of neonatal supracardiac and infracardiac total anomalous pulmonary venous, compared with the traditional surgical approach, the modified pericardial oblique sinus pathway can provide excellent surgical space and has a good surgical prognosis.
ObjectiveTo investigate the psychological states and their influencing factors in parents of congenital defect neonates admitted to Intensive Care Unit (ICU). MethodsThe self-designed general information questionnaire was used to collect the demographic data, and self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate the states of anxiety and depression of the parents of congenital defect neonates admitted to ICU between June 1 and November 29, 2013. ResultsA total of 152 parents were included in this investigation. The average score of SAS was 39.45±8.53. The average score of SDS was 43.28±10.76. Univariate analysis found that parents with lower educational level, poorer family income, positive family history and countryside residence might have higher score of SAS, while parents with Han nationality, poorer family income and family history would have higher score of SDS. Multivariate analysis discovered that living condition and family history were related to anxiety status. However, depression state was influenced by nationality, family income and family history. ConclusionA considerable number of parents of congenital defect neonates admitted to ICU have anxiety or depression. And nationality, family income, family history and living condition are the major risk factors.
摘要:目的:探討卡配因抑制劑3（MDL28170）對新生大鼠缺氧缺血性腦損傷(HIBD)神經細胞凋亡的影響。方法:建立新生SD大鼠HIBD模型,治療組于缺養缺血后即刻、2 h、4 h腹腔內注射MDL28170,對照組及手術組同時予生理鹽水。缺氧缺血后24 h用免疫組化方法觀察大腦皮質及海馬CA1區Caspase3 蛋白表達、TUNEL法檢測細胞凋亡,觀察組織病理改變并計算海馬神經元死亡數,透射電鏡觀察細胞超微結構。結果:缺氧缺血后24 h缺血側大腦皮質及海馬CA1區Caspase3和TUNEL陽性細胞數較對照組明顯增加,透射電鏡證實有凋亡細胞;MDL28170可減少陽性細胞數量,抑制神經元死亡,差異有顯著性(Plt;0.05)。結論:MDL28170可通過抑制神經凋亡而對新生大鼠HIBD具有一定保護作用。Abstract: Objective: To investigate the effect of (Calpain inhibitor3) MDL28170 on neural apoptosis in a neonatal model of hypoxicischemic brain damage (HIBD). Methods: A neonatal model of HIBD was established, 7dayold SD rats were divided into three groups. The treatment group received MDL28170(ip) at 0 h,2 h,4 h after HI, whereas the other two groups were administered normal saline simultaneously. The expression of caspase3 (by immunohistochemistry), neural apoptosis (by TUNEL) in cortex and hippocampus ipsilateral to the insult were observed 24 h after HI; hippocampal CA1 neural loss and electromicroscopic changes were assessed at the same time. Results: Apoptotic body was observed by electromicroscopy. Caspase3 positive cells and apoptotic cells increased significantly in the ipsilateral cortex and hippocampal CA1 region compared to the control, and MDL28170 reduced the number of positive cells, attenuated CA1 neural loss with significance (Plt;0.05). Conclusion: It is suggested that MDL28170 may protect the brain of neonatal rats after HIBD by suppressing neural apoptosis.
ObjectiveTo examine and compare the value of procalcitonin (PCT), C-reactive protein (CRP) and interleukin (IL)-6 in diagnosing fetal sepsis in premature neonates. MethodsPreterm neonates with premature rupture of membrane between January 2010 and September 2012 were screened, and the serum levels of PCT, CRP and IL-6 were detected in the first day of life. All preterm neonates were divided into two groups according to the development of sepsis (45 cases with sepsis and 39 cases without sepsis). ResultsThe levels of PCT, CRP and IL-6 in premature neonates with sepsis were all significantly higher than those without sepsis. The cut-off value of PCT in diagnosis of sepsis was 2.14 μg/L, with a sensitivity and specificity of 76% and 85% respectively; the cut-off value of CRP in diagnosis of sepsis was 7.90 mg/L, with a sensitivity and specificity of 67% and 61% respectively. For IL-6, the cut-off value in diagnosis of sepsis was 13.80 ng/L, and its sensitivity and specificity were high to 90% and 94%, respectively. ConclusionIL-6 is the most reliable biochemical marker for the detection of early-onset sepsis in preterm neonates with premature rupture of membrane.
摘要：目的：探討血小板動態變化與新生兒重癥肺炎之間的關系。方法：測定40例新生兒重癥肺炎患兒急性期（3天）及恢復期（10天）的血小板計數（platelet count, PLT）計數、平均血小板溶劑（mean platelet volume, MPV）、血小板壓積（platelet hematocrit, PCT）及血小板分布寬度（platelet distribution width, PDW），并進行比較。結果：40例重癥肺炎患兒中，PLT隨病情好轉而上升，PCT、MPV、PDW水平隨病情好轉而下降。急性期PLT、PCT、MPV、PDW的水平與恢復期相比，差異有統計學意義（Plt;0.05）。結論：動態的觀察血小板參數及其變化有助于新生兒重癥肺炎的評估及療效觀察。Abstract : Objective: To assess the relationship between neonatal severe pneumonia and platelet.

Results: Mean platelet volume, platelet count increased with recovery of pneumonia (Plt;0.05). Conclusion: Observing platelet change is helpful for the evaluation of neonatal pneumonia.
Objective To analyze the sutureless technique use in the surgical repair for total anomalous pulmonary venous connection in neonates. Methods Between September 2002 and December 2015, 71 consecutive neonates with supracardiac or infracardiac type total anomalous pulmonary venous connection who underwent surgical repair in our institute were included in this study. There were 57 males and 14 females at median age of 8 (1, 29) d. And the median body weight was 3.3 (2.1, 4.7) kg. There were 45 patients (63.4%) with supracardiac, 26 patients (36.6%) with infracardiac. Patients were divided into two groups: a conventional technique group (29 patients) and a sutureless technique group (42 patients). To control for potential differences in the characteristics of patients between the sutureless technique group and the conventional technique group, the method of propensity-score matching was used. Results Basic characteristics of patients after propensity-score were not different.There were 11 operative deaths (15.5%), 7 late deaths (96.%), total 18 deaths (25.4%). The mortality was 58.6% (17/29) in the conventional technique group, 2.4% (1/42) in the sutureless technique group (P=0.000). Kaplan-Meier survival curve showed a difference in mortality between the two groups (P=0.005). The patients were followed up for 25.5 (1.0-13.0) months.Postoperative anastomotic or pulmonary vein stenosis occurred in 12 patients, 8 of them died at a higher mortality than that of the patients with smooth anastomosis [66.7% (8/12) vs. 16.9% (10/59), P=0.001]. Conclusion The patients who have postoperative anastomotic or pulmonary vein stenosis have higher mortality. Compared with conventional technique, sutureless technique can dramatically decrease the incidence of postoperative anastomotic or pulmonary vein stenosis and the mortality of surgical repair for total anomalous pulmonary venous connection in neonates.
Objective To summarize the surgical treatment experience in neonates with coarctation of the aorta (CoA) and aortic arch hypoplasia (AAH). Methods The neonates with CoA and AAH who underwent surgical treatment in the Department of Pediatric Cardiac Surgery of Guangdong Provincial People's Hospital from 2013 to 2020 were retrospectively enrolled. The postoperative complications, long-term survival rate, and freedom from aortic reobstruction were analyzed. Patients undergoing extended end-to-end anastomosis were allocated into an extended end-to-end group, those undergoing extended end-to-side anastomosis into an extended end-to-side group, and those undergoing pulmonary autograft patch aortoplasty into a patch aortoplasty group.Results Finally 44 patients were enrolled, including 37 males and 7 females, aged 5.00-30.00 (19.34±7.61) days and weighted 2.00-4.50 (3.30±0.60) kg. There were 19 patients of extended end-to-end anastomosis, 19 patients of extended end-to-side anastomosis, and 6 patients of pulmonary autograft patch aortoplasty. The mean values of the Z scores of the proximal, distal, and isthmus of the aortic arch were –2.91±1.52, –3.40±1.30, and –4.04±1.98, respectively. The mean follow-up time was 45.6±3.7 months. There were 2 early deaths and no late deaths. Aortic reobstruction occurred in 8 patients, and 3 patients underwent reoperation intervention. The 5-year rate of freedom from reobstruction was 78.8%. The Cox multivariable regression analysis showed that the related factors for postoperative reobstruction were the Z score of the preoperative proximal aortic arch (HR=0.152, 95%CI 0.038-0.601, P=0.007) and the postoperative left main bronchus compression (HR=15.261, 95%CI 1.104-210.978, P=0.042). Conclusion Three surgical procedures for neonates with CoA and AAH are safe and effective, but the aortic reobstruction rate in long term is not low. The smaller Z score of the preoperative proximal aortic arch and the postoperative left main bronchus compression are risk factors for long-term aortic reobstruction.
Giant extralobar pulmonary sequestration in newborns is still relatively rare in pulmonary diseases, and there are few relevant studies published. A neonate with the giant extralobar pulmonary sequestration accompanied by severe pleural effusion was reported here. After 12 days of birth, the diseased lung tissue was surgically extracted. The patient had an uneventful postoperative recovery and was discharged from the hospital. The case shows the advantage of early surgical treatment to extralobar pulmonary sequestration with severe pleural effusion in neonatal period.
