  • Clinical Predictive Score for Acute Kidney Injury after Cardiac Surgery in Adults

    Objective To analyze risk factors of acute kidney injury (AKI) after cardiac surgery in adults and develop a clinical score system to predict postoperative AKI. Methods Clinical data of 3 500 consecutive patients undergoing cardiac surgery from June 2010 to April 2011 in Beijing Anzhen Hospital of Capital Medical University were retrospectively analyzed. According to whether they had postoperative AKI,all these patients were divided into AKI group and non-AKI group. AKI group was consisted of 1 407 patients (40.2%) with a mean age of 58±12 years,including 1 004 male patients (71.4%). The non-AKI group was consisted of 2 093 patients (59.8%) with a mean age of 55±13 years,including 1 259 male patients (60.2%). Predictive score system of postoperative AKI was established by univariate analysis between the AKI and non-AKI group and multivariate logistic regression and then verified. Results The predictive score system was as followed:male gender (2 points),every 5 years older than 60 years (1 point),diabetes mellitus (2 points),preoperative use of angiotensin converting enzyme inhibitor or angiotensin AT1 receptor blocker (1 point),every 10 ml / (min·1.73 m2) of preoperative estimated glomerular filtration rate (eGFR) under 90 ml / (min·1.73m2) (1 point),preoperative NYHA class Ⅳ (3 points),cardiopulmonary bypass time>120 minutes (2 points),intraoperative hypotension duration>60 minutes (2 points),postoperative hypotension duration>60 minutes (3 points),postoperative peak dosage of intravenous furosemide>100 mg/day (3 points),postoperative peak dosage of intravenous furosemide 60-100 mg/day (2 points),and postoperative mechanical ventilation time>24 hours (2 points). The predictive score system presented a good discrimination ability with the area under the receiver operating characteristic(ROC)curve of 0.738 with 95% CI 0.707 to 0.768,while it also presented a good calibration with Hosmer-Lemeshow statistic (P=0.305). Conclusion A clinical predictive score system for AKI after cardiac surgery in adults is established,which may help clinicians implement early preventive interventions.

  • Early Clinical Result of Total Cavopulmonary Connection

    Abstract: Objective To summarize early clinical result of total cavopulmonary connection, and analyze the risk factors contributing to prolonged postoperative recovery. Methods Between February 2009 and August 2010, 58 patients with functional univentricular complex congenital heart disease received total cavopulmonary connection in Beijing Fu Wai Hospital. All of them were diagnosed by echocardiogram and angiography including 26 patients with single ventricle, 10 patients with tricuspid atresia, 4 patients with pulmonary artery atresia, 5 patients with double outlet rightventricle, 1 patient with transposition of great arteries, and 12 patients with corrected transposition of the great arteries.Fifty seven patients underwent extracardiac conduit total cavopulmonary connection, and only one patient underwent total cavopulmonary connection with an intracardiac lateral tunnel. According to their postoperative pleural drainage volume and duration, these 58 patients were divided into a large pleural drainage volume group (17 patients with 10 males and 7 females, mean age of 8.61±6.73 years)that included patients with large volume and long duration of pleural drainage, and a little pleural drainage volume group (41 patients with 15 males and 26 females, mean age of 7.21±4.24 years) . A univariable analysis was conducted to compare the risk factors that effected recovery result between the two groups. Results There was no death in hospital period. The average length of hospital stay was 12.30±9.80 d . Average drainage time (18.00±5.50 d versus 5.00±2.20 d , t= -1.967, P < 0.05), drainage volume (12.30±2.60 ml/(kg·d) versus 2.80±1.70 ml/(kg·d), t=-3.221, P < 0.05), and hospital stay (20.10±7.20 d versus 7.20±1.10 d, t=-2.003, P < 0.05) of the large pleural drainage volume group were significantly larger or longer than those of the little pleural drainage volume group. Univariate analysis showed that preoperative pulmonary pressure measured by catheter in the large pleural drainage volume group was significantly higher than that in the little pleural drainage volume group (17.42±5.34 mm Hg versus 13.91±5.22 mm Hg,t=-2.073,P < 0.05). Conclusions The mortality and major morbidities after total cavopulmonary connection are low in the current era. Preoperative high pulmonary pressure is a risk factor for large amount of pleural drainage and prolonged recovery.

  • Mid-term Outcomes after Correction of Type Ⅰ and Type Ⅱ Persistent Truncus Arteriosus

    Abstract: Objective To analyze the mid-term outcomes after correction of type Ⅰ and type Ⅱ persistent truncus arteriosus in all patients operated in our institution over the past 5 years. Methods Between May 2006 and October 2010, 17 patients, mean age 4.7( 0.7-19.0)years, underwent repair of truncus arteriosus( type Ⅰ in 13 and type Ⅱ in 4) in Fu Wai Cardiovascular Hospital. Some other concomitant cardiovascular malformations included truncal valve regurgitation, partial anomalous pulmonary venous connection, mitral regurgitation and atrial septal defect. Their average pulmonary vascular resistance was (4.4±2.2) Wood units detected by cardiac catheterization before operation. Repair with reconstruction of the right ventricular to pulmonary artery continuity was performed using a valved conduit in all 17 patients (aortic homografts in 3, pulmonary homografts in 2, and bovine jugular vein in 12 patients). Survivors were followed up for assessment of residual heart lesions. Results The early mortality was 5.8% (1/17). The mean cardiopulmonary bypass time was (165±52) min, mean aortic cross-clamping time was (114±29) min, and mean postoperative ventilation time was (106±148) h. Two patients had pleural effusion after surgery, 2 patients underwent tracheostomy, and other patients recovered uneventfully. The surviving 16 patients were followed up for 0.6-5.0 years. All patients were alive with their original conduit during follow-up. No patient required re-operation for conduit dysfunction after correction. Conclusion Truncus arteriosus remains a challenging congenital heart disease. For patients with type Ⅰ and type Ⅱ persistent truncus arteriosus who have missed their best age for correction, cardiac catheterization should be routinely examined, and the operation should be performed if the pulmonary vascular resistance is under 8 Wood units before operation. Although the short- and mid-term results of surgery are good, more observations are needed to assess its long-term effect.

  • STUDY ON THE MOLECULAR MECHANISMS INVOLVED IN THE INCREASED COLLAGEN SYNTHESIS BY PLATELET-DERIVED WOUND HEALING FACTORS DURING WOUND HEALING IN ALLOXAN-INDUCED DIABETIC RAT

    OBJECTIVE: To explore the molecular mechanisms involved in the increased collagen synthesis by platelet-derived wound healing factors (PDWHF) during wound healing in alloxan-induced diabetic rats. METHODS: Thirty-three male SD rats were divided into two groups, the normal (n = 9) (group A) and the diabetic group (n = 24). Two pieces of full-thickness skin with diameter of 1.8 cm were removed from the dorsal site of diabetic rats. PDWHF (100 micrograms/wound) was topically applied to one side of the diabetic wounds (group B) on the operation day and then once a day in the next successive 6 days. Meanwhile, bovine serum albumin (100 micrograms/wound) was applied to the other side of diabetic wound as control group (group C) in the same way. Levels of transforming growth factor-beta 1 (TGF-beta 1) and procollagen I mRNA in wound tissue were inspected by dot blotting. RESULTS: TGF-beta 1 mRNA levels in group B were 4 folds and 5.6 folds compared with those in group C after 5 and 7 days (P lt; 0.01), however, still significantly lower than those of group A (P lt; 0.05). There was no significance difference among three groups on the 10th day after wounding. The levels for procollagen I mRNA in group B amounted to 2.1, 1.8 and 2.3 folds of those in group C after 5, 7, and 10 days (P lt; 0.01), respectively. Compared with those in the group A, procollagen I mRNA levels in the group B were significantly lower after 5 and 7 days (P lt; 0.05), and no significant difference was observed between group B and A after 10 days. CONCLUSION: One important way for PDWHF to enhance the collagen synthesis in diabetic wound healing is to increase the gene expression of endogenous TGF-beta 1.

  • Evaluation of the Quality of Reports on Acupuncture for Migraine Prophylaxis

    Objectives We aimed to assess the methodological qual ity of RCT on acupuncture for migraine prophylaxis. Methods With the searching terms including acupuncture, migraine, prophylaxis and prevent, etc, the database of the Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMBase (1966-2007), CBM (1978-2007) and CMCC (1994-2007) were searched from their date of start publ ication. Chinese medical journals and relevant academic conference proceedings were hand searched as well. Several items in included trials were assessed, including methodology, diagnostic criteria, inclusion/exclusion criteria, acupuncture/control interventions, outcome measures and follow-up, etc. Result Among the 12 included trials, 9 trials overseas were high-qual ity and 3 in China were low-quality. Frequency or days of migraine attacks and SF-36/SF-12 were often evaluated as outcome measures in western countries, while headache index was used in China. Among the 12 trials, 9 reported the follow-up outcomes and 8 mentioned adverse events. Conclusion There was no high qual ity trial on acupuncture for migraine prophylaxis in China. The outcome measures in trials published in China by now can not evaluate the outcomes of acupuncture for migraine prophylaxis accurately. To study designs, advantages of trials oversea can be used for reference. To Chinese cl inical physicians, prophylactic therapy and abortive therapy of migraine should be distinguished in order to design high-qual ity study on acupuncture for migraine prophylaxis.
