Objective To investigate the clinical value of peripheral serum cell-free DNA/neutrophil extracellular traps (cf-DNA/NETs) level in diagnosis and severity assessment of sepsis patients. Methods Forty patients with sepsis and 40 patients with non-infectious systemic inflammatory response syndrome (nf-SIRS) were enrolled in this study. The cf-DNA/NETs level in serum of all subjects were measured. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic ability of the cf-DNA/NETs, white blood cell count (WBC), procalcitonin (PCT) and interleukin-6 (IL-6). The sepsis patients were stratified into a survival group and a death group according to the prognosis. Sequential organ failure (SOFA) score were recorded in the sepsis patients, and the correlations between SOFA and cf-DNA/NETs, PCT, WBC, IL-6 were analyzed. Results Compared with the nf-SIRS group, cf-DNA/NETs and PCT levels were significantly higher in the sepsis group (both P<0.05). WBC and IL-6 showed no significant differences between the two groups (bothP>0.05). The area under the ROC curve (AUC) of cf-DNA/NETs was 0.884 for diagnosis of sepsis, and it was higher than the AUC of PCT (0.803). The cf-DNA/NETs showed better sensitivity (81.2% and 79.2%) and specificity (81.0% and 82.4%) than PCT. cf-DNA/NETs and PCT were significantly higher in the death group than those in the survival group. Bivariate collection analysis revealed positive correlations between SOFA score and the two biomarkers of cf-DNA/NETs and PCT (r1=0.573, r2=0.518; both P<0.01). Conclusions cf-DNA/NETs and PCT have certain value in early diagnosis of sepsis, and cf-DNA/NETs shows better diagnostic value in distinguishing sepsis from nf-SIRS than PCT. cf-DNA/NETs can be used as a routine monitoring index to help assess disease severity in sepsis.
Objectives To assess the effectiveness and safety of lumbar continuous drainage of the cerebrospinal fluid therapy for subarachnoid hemorrhage (SAH). Methods The method of Cochrane systematic review was used to evaluate the randomized controlled trials (RCTs) of lumbar contiunous drainage of the cerebrospinal fluid therapy for SAH. Results We included 7 RCTs involving 390 patients. The methodological quality of all the trials was poor. The poor outcome and adverse event evaluation of the SAH patients at the end of long-term follow-up (at least three months) were not reported in all studies. Meta-analysis of fatality showed a better effect of lumbar continuous drainage of the cerebrospinal fluid therapy for SAH than the control group with statistical significance [RR=0.32, 95%CI (0.15, 0.70)]. Meta-analysis of complications also showed a better effect of lumbar continuous drainage of the cerebrospinal fluid therapy for SAH than the control group with statistical significance (except re-bleeding) [cerebral vasospasm RR=0.15, 95%CI (0.06, 0.33), hydrocephalus RR=0.22, 95%CI (0.10, 0.52), cerebral infarction RR=0.25, 95%CI (0.08, 0.82)]. Only one trial reported the adverse events of lumbar continuous drainage of the cerebrospinal fluid therapy including intracranial infection and intracranial hypotension reaction, while the other trials did not report the adverse events. Conclusion With poor quality of the most included trials, insufficient evidence is obtained to support the conclusion that lumbar continuous drainage of the cerebrospinal fluid therapy is safe and effective in the treatment of SAH. Further high-quality RCTs should be carried out to provide more reliable evidence.

Methods A total of 120 patients with CHD diagnosed by coronary arteriongraphy between October 2008 and April 2010 were enrolled. The patients were divided into two groups: CHD group (60 patients); CHD accompanied with T2DM group (60 patients). The levels of serum insulin, adiponectin and RBP4 were measured. All the patients underwent coronary angiography and the extent of coronary lesions was assessed quantitatively based on the Gensini′s scoring system. Results The levels of serum insulin, plasma RBP4 and the extent of coronary artery stenosis in CHD accompanied with T2DM group were significantly higher than those in CHD group (Plt;0.05). Correlation analysis showed that the level of RBP4 was positively correlated with LDL-C, insulin resistance index and the coronary artery narrow degree（r=0.312, 0.322, 0.314; Plt;0.05); and negatively correlated with adiponectin (r=-0.362, Plt;0.01). Conclusion The significant elevated plasma RBP4 in CHD patients accompanied with T2DM is positively correlated with the extent of coronary artery lesion.

Methods From January to April 2008, 35 patients with T2DM (group A1: HOMA-IRlt;2.69, n=19; group A2: HOMA-IR≥ 2.69, n=16) and 20 subjects without T2DM (group B) were enrolled. The body mass index (BMI), fasting plasma glucose (FPG), insulin (FINS), atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and E/A, e/a, S/D, LVEF and DT stage of all subjects were detected. Results The BMI in group A2 was higher than those in group A1 and group B (Plt;0.05), while the difference between the later two groups was not statistically significant (Pgt;0.05). The ANP, BNP and DT stage were all higher than those in group B (Plt;0.05), the BNP was higher in group A2 than in group A1 (Plt;0.05), while the difference of neither ANP nor DT stage between the later two groups was statistically significant (Pgt;0.05). The values of E/A, e/a and S/D in group A1 and A2 were all lower than those in group B (Plt;0.05), while there were no statistically significant diferences between group A1 and A2 (Pgt;0.05). The values of LVEF of group A1 and A2 were both significantly reduced than that in group B (Plt;0.05), and the values in group A2 were the lowest (Plt;0.05). Conclusion With the aggravating of insulin resistance, myocardial contractility and diastolic function will decline, meanwhile the ANP and BNP secretion will increase, and then the clinical and echocardiographic manifestation will appear.
【摘要】 目的 分析手术治疗垂体瘤患者长期临床恢复以及生活质量改善情况。 方法 回顾性分析2007年12月-2008年9月手术治疗的103例垂体瘤患者术前以及术后长期随访资料，使用SF-36量表对术前、术后患者生活质量进行评估，分析手术治疗前后患者症状、激素水平恢复情况以及生活质量改善情况，并进一步分析肿瘤大小、侵袭程度对术后生活质量的影响。 结果 术后头痛症状消失52例，视力改善76例，其他症状具有不同程度改善；术后SF-36生活质量评估结果显示，患者除精神健康外的7个维度（生理机能、生理职能、躯体疼痛、一般健康状况、精力、社会功能、情感职能）均有明显改善（P＜0.05），不同肿瘤大小及侵袭程度的患者术后生活质量评分均无统计学意义（P＞0.05），垂体功能完全恢复者生活质量评分高于垂体功能低下者（P＜0.05）。 结论 显微手术治疗垂体瘤患者可明显改善患者的一般症状、提高患者的生活质量，单纯肿瘤的大小和侵袭程度对术后生活质量的影响程度较小，术后垂体功能的恢复程度明显影响患者的生活质量，垂体瘤术后患者的激素长期替代治疗尚需进一步加强。【Abstract】 Objective To analyze the long-term clinical recovery and quality of life (QoL) in patients with pituitary adenoma treated by microneurosurgery. Methods The clinical data of 103 patients undergoing microneurosurgery from December 2007 to September 2008 were retrospectively analyzed, health-related questionnairs (SF-36) were used to assess the QoL. The post-surgery recovery of symptoms, endocrine function, and QoL were compared with those of pre-surgery, then the correlation between tumor size, invasive behavior, and QoL were analyzed. Results Headache disappeared in 52 patients. Visual symptoms improved in 76 patients. Other symptoms were also improved. Seven concepts (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotioning) were improved after surgery (Plt;0.05). The eight health concepts of SF-36 showed no significant difference between patients with different tumor size and invasive behavior (Pgt;0.05). Differences were considered statistically significant between normal and abnormal pituitary function groups after surgery(Plt;0.05) in all concepts. Conclusion Microneurosurgical treatment can improve the general symptoms and the QoL. The tumor size and invasion have little influence on the QoL after surgery, but the improvement of hormone deficiency has influence on the QoL significantly. More attention should be given to the long-term hormone replacement therapy after the pituitary adenoma surgery.
ObjectiveTo explore the early results of Ozaki operation in children with aortic regurgitation.MethodsWe retrospectively analyzed the clinical data of 15 patients with aortic regurgitation who received the Ozaki operation in our hospital from April 2017 to July 2019. There were 11 males and 4 females with an average operation age of 10.7±3.7 years. Besides preoperative evaluation, aortic regurgitation and cardiac function were evaluated on 1 day, 1 week, 1 month, 3 months, and 6-12 months after surgery.ResultsIn 14 (93.3%) patients , the aortic valve leaflets functioned well on 1 day, 1 month, 3 months, and 6-12 months, and the regurgitation grade was Ⅰ-Ⅱ, which was improved than before (P=0.001). The cardiac function of children recovered quickly after operation. There was no statistical difference in ejection fraction on 1 day, 1 month, 3 months, and 6-12 months after operation (P>0.05). No children died, and no other clinical event was found.ConclusionThe Ozaki technique of reconstructing a tricuspid aortic valve leaflet for the treatment of severe aortic regurgitation in children is effective in short term, and the persistence of its valve function remains to be determined in the long-term follow-up.
Aortic regurgitation (AR) is a common heart valve disease, and aortic valve replacement is an important treatment at present. With the advent of new methods such as transcatheter aortic valve replacement, patients with high-risk AR have been effectively treated. In particular, the emergence of new generations of transcatheter prosthetic valve systems has made the treatment of patients with AR more and more abundant. To treat patients with AR, it is necessary to establish the concept of “once diagnosed, lifelong management”, delay the progression of the disease through various means, and ultimately reduce the mortality of patients with AR and improve the quality of life. Therefore, this article reviews the basic characteristics of AR patients in China, the development and challenges faced by transcatheter aortic valve replacement surgery, follow-up, and postoperative rehabilitation plans, aiming to help physicians use different methods in a reasonable and standardized manner when facing AR patients with different causes and disease progression, and achieve the goal of achieving correct and effective lifelong management of AR patients.
ObjectiveTo discuss outcomes of arch reintervention for post-repair recoarctation in children.MethodsFrom 2009 to 2019, 48 patients underwent reintervention for post-repair recoarctation in Shanghai Children’s Medical Center. Of the 48 patients, 22 patients had surgical repair, 25 patients had balloon angioplasty (BA), and 1 patient had a stent implantation. The clinical data were analyzed, and the difference in time-to-event distribution between the surgical group and the BA group was determined by a log-rank test.ResultsThe median age at reintervention was 15.0 months (range, 3.0 months-15.1 years). The median weight at reintervention was 9.8 kg (range, 3.0-58.0 kg). The time to reintervention after initial repair was 12.5 months (range, 2.0 months-7.8 years). One patient (2.1%) died in hospital and 1 patient (2.1%) experienced arrhythmia after surgical repair. One late mortality (2.1%) occurred after surgical reintervention. One patient (2.1%) experienced aortic dissection after BA. No patient died after BA. Freedom from residual coarctation or new recurrences was 66.7%, 61.3%, and 56.9%, respectively, at 1, 2, and 5 years after reintervention. Freedom from residual coarctation or new recurrences was 90.0%, 81.8%, and 70.1%, respectively, at 1, 2, and 5 years after surgical repair. Freedom from residual coarctation or new recurrences was 52.0%, 48.0%, and 48.0%, respectively, at 1, 2, and 5 years after BA. Compared with BA, surgery-based reintervention had a lower incidence of residual coarctation or recurrences (χ2=4.400, P=0.036).ConclusionReintervention for recoarctation has favorable early outcomes. Compared with balloon angioplasty, surgical repair has a more lasting effect in relieving the recoarctation.
ObjectiveTo 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. ResultsFinally 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. ConclusionWhether 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.
ObjectiveTo explore growth pattern of neo-aortic root as well as development of neo-aortic regurgitation after arterial switch operation (ASO) for Taussig-Bing anomaly. MethodsFrom 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. ResultsA 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). ConclusionThe 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.
