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 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.
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.
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 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.
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.
Abstract: Objective To investigate the safety and feasibility of fast track (FT) treatment in young children with atrioventricular septal defect (CAVSD) and pulmonary artery hypertension (PAH) following surgical repair. Methods A total of 51 young children patients including 24 boys and 27 girls with age at 12.5±8.9 months from 4 to 36 months, underwent CAVSD repair in the pediatric surgery department of Fu Wai Hospital from January 2006 to March 2009. Among them, 21 patients were administered FT management. PICU length of stay and the rate of reintubation were analyzed retrospectively and the decrease of pulmonary artery pressure (PAP) after operation was also measured. Results Twentyone patients under FT treatment were extubated within 8 hours after operation. The mean pulmonary artery pressure(MPAP) decreased significantly after surgery (39.59 mm Hg vs.24.50 mm Hg,t=5514,Plt;0.05). PICU length of stay was 2.05±0.87 d (18 h-3 d). One patient was reintubated due to lung infection, which had nothing to do with the FT treatment. During the followup which lasted for 3 to 6 months, 21 patients had good heart function with no reoperation or death. Conclusion FT treatment is safe and feasible to some CAVSD patients associated with PAH, and shorter PICU length of stay can be achieved. The validation of FT model for the CAVSD patients with severe PAH needs research with large sample.
Objective To investigate the iron deficiency (ID) in children with congenital heart disease (CHD) and find high risk factors of ID. Methods The clinical data of 227 pediatric patients with CHD from February to June 2016 were retrospectively analyzed. The incidence of ID according to the result of iron metabolism examination (serum ferritin <12 μg/L as the diagnostic criteria) was investigated. According to their basic CHD types, patients were divided into a cyanotic group and an acyanotic group. We tried to find the high risk factors of ID in those pediatric CHD patients by comparing their age, gender, growth condition and blood routine test results. Results There were 19.8% pediatric CHD patients complicated by ID. The incidence of ID in the cyanotic patients was higher than that in the acyanotic patients (31.0% vs. 17.3%, P=0.045). In both groups, ID patients presented the characteristics of younger age, higher anemia rate, lower mean corpuscular volume (MCV), lower mean corpuscular hemoglobin (MCH), lower mean corpuscular-hemoglobin concentration (MCHC) and longer red blood cell distribution width (RDW). Conclusion Cyanosis, younger age (infant), anemia, decreased MCV, decreased MCH, decreased MCHC and increased RDW are high risk factors of ID in CHD children.
