目的 探討Ⅰ型先天性膽總管囊腫的手術治療。方法 回顧性分析筆者所在醫院1987年3月至2011年6月期間收治的42例Ⅰ型先天性膽總管囊腫患者手術治療后的效果。結果 本組中2例因并發腹膜炎先行囊腫外引流術后4周再行囊腫空腸吻合術；3例直接行囊腫空腸吻合術；35例行囊腫切除肝總管空腸Roux-en-Y吻合術；2例行囊腫切除間置空腸肝總管十二指腸吻合術。手術成功率為100%。5例內引流術（囊腫空腸吻合術）后均有不同程度的膽道感染癥狀。37例行囊腫根治術（即囊腫切除肝總管空腸Roux-en-Y吻合或間置空腸肝總管十二指腸吻合術）中有2例囊腫切除肝總管空腸Roux-en-Y吻合術后患者偶有右上腹隱痛不適，經X線鋇餐檢查，診斷為膽管逆行性感染，抗炎治療有效；其余病例無腹痛、黃疸、發熱、再生結石、吻合口狹窄、癌變及其他手術并發癥。結論 囊腫外引流術僅作為急診手術，待患者一般情況改善后再行第二次手術；囊腫根治術是治療Ⅰ型先天性膽總管囊腫理想的手術方式。
Objective To explore risk factors related to acute kidney injury (AKI) in children who underwent corrective surgery for tetralogy of Fallot (TOF). Methods We retrospectively analyzed the clinical data of 726 children with corrective procedures for TOF aged less than 3 years in our hospital from March 1st 2010 to March 1st 2013. Children with AKI were picked using Acute Kidney Injury Network criteria. Demographic and perioperative variables of the remaining patients were reviewed. Univariate analysis was performed to compare the AKI group (240 patients) with the non-AKI group (486 patients). Multivariable analysis was carried out to identify significant determinants of AKI. Results A total of 240 children were with AKI. The result of univariate analysis showed that there was a statistical difference in age, Nakata index, McGoon ratio, left ventricular end-diastolic volume index (LVEDVI), transannular right ventricular outflow tract (RVOT) patch, or fresh frozen plasma (FFP) in prime solution between the AKI group and the non-AKI group. Multivariable logistic regression showed that in older children (OR=1.425, 95% CI 1.071 to 1.983, P=0.011) with more transfusion of FFP in the priming solution (OR=1.486, 95% CI 1.325 to 2.674, P<0.001) led to higher morbidity of mild AKI. In addition, there was an increase in morbidity related to AKI when children had less Nakata index (OR=0.282, 95% CI 0.092 to 0.869, P=0.013). Conclusion Postoperative AKI increases in older children group. Infusion of more FFP in priming solution increases morbidity of AKI. The less Nakata index is significantly associated with severe AKI.
Objective To study the expression of inducible nitric oxide synthase (iNOS)，endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) in human gastric cancer and their relationship with tumor angiogenesis and to investigate the interaction of NOS and VEGF in gastric cancer. Methods The expression and distribution of VEGF, iNOS and eNOS in 34 gastric cancer specimens were detected with immunohistochemistry. Microvessel density (MVD) was counted with FⅧRAg immune specific staining. Results The expression rates of iNOS, eNOS and VEGF in 34 gastric cancers were 73.5%, 82.4% and 91.2% respectively. The expression of VEGF had a significant positive relation with iNOS, but not with eNOS. The MVDs of VEGF or iNOS positive gastric cancers were obviously higher than those of VEGF or iNOS negative gastric cancers. There was no significant difference between the MVDs of eNOS positive gastric cancers and eNOS negative ones. Conclusion MVD increases with increase of expression of VEGF and iNOS in gastric cancer. It is indicated that VEGF and iNOS can promote gastric cancer angiogenesis. VEGF and iNOS have a significant positive correlation, which suggests that in human gastric cancer, iNOS plays an important role in the production and action of VEGF.
The success of staged Fontan palliation for patients with single ventricle is related to low pulmonary vascular resistance (PVR). The complications of high PVR in Fontan physiology are numerous, such as low exercise tolerance, low cardiac output, ventricular function failure and protein-losing enteropathy; eventually it leads to failing Fontan. Therefore, a low PVR is crucial in Fontan patients. Now, targeted therapies decreasing PVR has been an advanced research hotspot in Fontan patients. In this review we present an overview of the safety and efficacy of the therapy with bosentan or sildenafil on elevated pulmonary artery pressure and pulmonary vascular resistance in Fontan patients.
Objective Tho evaluate the outcomes of early percutaneous occlusion of these residual major aortopulmonary collateral arteries after heart surgery. Methods This was a retrospective review of children undergoing early percutaneous embolization of major aortopulmonary collateral arteries after cardiac surgery. From January 2013 to February 2017, 52 consecutive patients with postoperative residual major aortopulmonary collateral arteries were treated with percutaneous embolization (38 males, 14 females; median age of 10.0 months, interquartile range 14.0 months; median weight 8.6 kg, interquartile range 4.4 kg). Fifty-one patients were cyanotic and 1 patient was acyanotic. Forty-nine patients underwent corrective surgery and 3 patients underwent B-T shunt. Results Typical symptoms and signs of major aortopulmonary collateral arteries included: elevated left atrial pressure; focal lung infiltration, pink or blood-stained frothy sputum. The median time interval from cardiac surgery to percutaneous occlusion of major aortopulmonary collateral arteries was 5 (9) d, median duration of mechanic ventilation support since occlusion was 72 (159) h, mechanic ventilation support was 239 (480) h and median duration of intensive care unit was 19 (29) d. There was no death in this group. Conclusion Angiocardiography could be able to demonstrate the existence of postoperative major aortopulmonary collateral arteries. The early percutaneous occlusion appears to be simple, safe and effective.
ObjectiveTo compare attitudes of nursing undergraduates to patients with mental illness before and after learning psychiatric nursing course and provide evidence for the improvement of teaching of the course. MethodsStigma scale to patients with mental illness was used as a questionnaire for collecting data, which was conducted on nursing undergraduates taking psychiatric nursing course between March and June 2012. Paired t-test was used to compare the differences between students' attitudes before and after learning the course. ResultsSignificant difference was found for danger factor (P<0.05), while there was no statistically significant difference in the social isolation factor and social ability factor before and after the psychiatric nursing course (P>0.05). ConclusionPsychiatric nursing course has a great influence on students' evaluation of the danger of patients with mental illness which reduces the discrimination against the patients.
Objective To introduce the current status of clinical research on endoscopic cholecystolithotomy with reservation of gallbladder. Methods Literatures related to the basis, advantage, indication, contraindication, operative method and current controversy were reviewed and summarized. Results The objective evidences were afforded by postoperative complications of cholecystectomy for endoscopic cholecystolithotomy with reservation of gallbladder. The progress of endoscopic technique made it possible for reservation of gallbladder. The controversy in endoscopic cholecystolithotomy with reservation of gallbladder was focused on the choice of indications and operative procedure. Incorrect patient selection and undue pursuit of cholecystolithotomy with reservation of gallbladder would be completely opposite to the treatment of gallstone. Conclusion It is feasible for endoscopic cholecystolithotomy with reservation of gallbladder to remove completely stone and reserve gallbladder function, but further investigation and long-term follow up are required to delineate gallstone recurrence after operation.
