Objective To introduce the technique of surgical patch angioplasty for the treatment of patients with isolated left main coronary artery stenosis. Methods Retrospective investigation of results of surgical patch angioplasty in patients with isolated left main coronary artery disease. Results All 8 patients who underwent left main coronary artery patch angioplasty survived with no major perioperative complications. One patient had recurrent angina and required coronary artery bypass grafting 6 months after patch angioplasty. All other patients were symptom free and had normal activity, at a mean follow-up of 5. 3 years. Conclusions Patch angioplasty can be used as an alternative surgical technique in cases of isolated left main coronary artery stenosis with no distal coronary artery disease. However, it may not be suitable for patients with significant left main coronary artery calcification.
Objective To summarize the significance of BRAFV600E mutation for the diagnosis, treatment, and prognosis of papillary thyroid cancer (PTC). Methods Related literatures which were published in recent years for exploring the relationship of BRAFV600E mutation and PTC were collected and reviewed. Results The BRAFV600E mutation was the most common mutant type in PTC, which played an important role in the oncogenesis and development of PTC. In addition, this type of mutation was closely associated with aggressive behavior and poor prognosis of PTC. The BRAFV600E testing in fine needle aspiration (FNA) samples of thyroid nodule not only facilitated to improve the diagnostic accuracy of PTC, but also helped ensure the recurrence risk classification, selection of surgical treatment, and follow-up planning. Conclusion BRAFV600E mutation was prevalent in PTC and had important significance both in diagnosis and prognostic evaluation of PTC.
Objective To compare the clinical value of Acute Physiology and Chronic Health Evaluation ( APACHE) Ⅱ / Ⅲ scoring system in predicting the prognosis of patients complicated with acute kidney injury ( AKI) and multiple organ dysfunction syndrome ( MODS) in ICU. Methods 318 patients with AKI and MODS treated with continuous blood purification in ICU fromJanuary 2004 to June 2010, were evaluated with APACHE Ⅱ and APACHEⅢ and analyzed retrospectively. The area under the receiveroperating characteristic curve ( AUC) and the Lemeshow-Hosmer goodness-of-fit of APACHEⅡ and Ⅲ were assessed. Results Mean scores and predicted hospital mortality of APACHEⅡ and Ⅲ were all significantly lower in the survival group than those in the non-survival group ( P lt; 0. 01) . The AUC were 0. 782 for APACHEⅡ, and 0. 755 for APACHEⅢ, with Youden’s indexes of 46. 4% and 36. 7% , respectively. Hosmer-Lemeshow test showed the calibration of the two systems was reasonable. Conclusion APACHEⅡ and Ⅲ are both good for predicting the severity and prognosis of patients complicated with AKI and MODS in ICU but APACHEⅡ is superior in clinical practice.
【Abstract】 Objective To di scus s the resect ion of tumors of pelvic ring and i t s recons truct ion ofdefects. Meth ods From January 1999 to December 2006, 48 patients with tumors in pelvic ring were treated and defects were reconstructed. There were 32 males and 16 females, aged 14-72 years(mean 45.1 years), including 12 cases of benign tumor and 36 cases of mal ignant tumor. Fourteen cases had lesions in region Ⅰ , 11 cases in region Ⅱ , 12 cases in region Ⅲ , 3 cases in region Ⅳ and 8 cases had two or more regions. The selection of surgical method: benign tumor in wing of il ium or in sacro-il iac articulation was curettaged , mal ignant tumors were resected radically or boardly . Benign or mal ignant tumor in pubis, ischium or pubic symphysis was resected radically , defects were reconstructed with plastic plate or not. For tumor affecting aceta bulum , resection of tumor and replacement of the peri- pelvic prothetic or artificial hip joint replacement were performed to reconstructthe function of hip joint. Results Twelve patients with benign tumors were followed up 12-72 months and could walk well, only 1 case relapsed locally. Thirty-six patients with mal ignant tumor were followed up 6 - 72 months, the survival time was 6-12 months in 2 cases (5.6%), 12-24 months in 2 cases(5.6%), 24-36 mongths in 6 cases (16.7%), 36-72 months in 14 cases (38.8%), and more than 72 months in 12 cases (33.3%); 28 patients (77.8%) could walk normally, 6 (16.7%) could walk with the help of walking stick , 2(5.5%) needed wheel chair to move. Compl ications occurred in 6 cases( including 2 venous thrombus,1 anoxic encephalopathy, 2 wound delayed heal ing, and 1 dislocation after total hip joint replacement); the patients’ condition took a turn for the better. Conclusion Operation is a favorable way for the treatment of pelvic tumor. Selecting convenient operation methods to resect tumors or reconstruction defects according the position of the tumor will do good favor to good results,increase the survival time and improve qual ity of l ife.

ObjectiveTo investigate the clinical features, diagnosis and treatment of scedosporiosis in lung transplant patients.MethodsA retrospective analysis was carried out on a lung transplant patient with scedosporiosis admitted to the First Affiliated Hospital of Guangzhou Medical University. A literature review was performed with “scedosporium”/“scedosporiosis”+“lung transplant” or “scedosporium”/“scedosporiosis”+“lung transplantation” as the key words in Pubmed, Wanfang Database and China Knowledge Resource Integrated Database. The date of retrieval was up to May 2018. Related articles of scedosporiosis in lung transplant patients were retrieved. Clinical characters, diagnosis, treatment and outcome were analyzed.ResultsThe patient was a 65 years old male who received the right lung transplantation 7 months before. He presented with seizure, dyspnea and multiple organ failure. The CT scan illustrated right lower pulmonary nodular lesions. The culture and DNA sequencing of the bronchoalveolar lavage fluid established the diagnosis of scedosporium prolificans. The patient died finally despite the combined anti-fungal treatment. Literature review found 20 relative articles, and all of which were case report with a total of 35 patients. Scedosporium was always disseminated and with a high mortality, with no specificity in chest CT and bronchoscopy. The diagnosis always established by the culture and DNA sequencing, and the combination of anti-fugal agents was needed.ConclusionsScedosporium in lung transplant patient is a disseminated disease with high mortality. The high risk patients should be focused on and early diagnosis and treatment was demanded.
ObjectiveTo explore the effect on sagittal spine-pelvis balance of different fusion segments in anterior cervical discectomy and fusion (ACDF).MethodsThe clinical data of 326 patients with cervical spondylotic myelopathy, treated by ACDF between January 2010 and December 2016, was retrospectively analysed. There were 175 males and 151 females with an average age of 56 years (range, 34-81 years). Fusion segments included single segment in 69 cases, double segments in 85 cases, three segments in 90 cases, and four segments in 82 cases. Full spine anterolateral X-ray films were performed before operationand at 12 months after operation. The spine-pelvis parameters of fusion segments were measured and compared. The parameters included C0-2 Cobb angle, C2-7 Cobb angle, C2-7 sagittal vertical axis (C2-7 SVA), T1 slope (T1S), thoracic inlet angle (TIA), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), C7 sagittal vertical axis (C7 SVA), T1 pelvic angle (TPA). The Japanese Orthopaedic Association (JOA) score of cervical spine and visual analogue scale (VAS) scores of pain of cervical spine and upper extremity were compared before operation and at 12 months after operation. Pearson correlation analysis was performed on LL, PI, SS, C7 SVA, and TPA before and after operation to evaluate the changes of spine-pelvis fitting relationship after ACDF.ResultsAll 326 patients were followed up 12-32 months (mean, 18.5 months). During the follow-up period, internal fixator was in place, and no spinal cord nerve or peripheral soft tissue injury was found. JOA scores and cervical VAS scores improved significantly at 12 months after operation (P<0.05), no significant difference was found in VAS scores of upper extremity when compared with preoperative scores (P>0.05). The preoperative cervical VAS scores and the postoperative JOA scores at 12 months had significant differences between groups (P<0.05). At 12 months after operation, there was no significant difference in sagittal spine-pelvis parameters in the single segment group compared with preoperative ones (P>0.05); but the C0-2 Cobb angle, C2-7 Cobb angle, C2-7 SVA, T1S, TIA, C7 SVA, and TPA in the double segments, three segments, and four segments groups were significant larger than preoperative ones (P<0.05). The C0-2 Cobb angle, C2-7 Cobb angle, T1S, C7 SVA, and TPA among 4 groups had significant differences before operation and at 12 months after operation (P<0.05). At 12 months after operation, the changes of C7 SVA and TPA in the double segments, three segments, and four segments groups were significantly larger than those in the single segment group (P<0.05). PI had positive correlations with LL and SS before and after operation in 4 groups (P<0.05).ConclusionNormal fitting relationship between lumbar spine and pelvis in physiological state also exists in patients with cervical spondylotic myelopathy, and ACDF can not change this specific relationship. In patients with cervical spondylotic myelopathy, the sagittal spine-pelvis sequence do not change after ACDF single-level fusion, while the sagittal spine-pelvis balance change after double-level and multi-level fusion.
ObjectiveTo explore the continuous changing trend of healthcare-associated infection prevalence rate in a children’s hospital.MethodsFrom July 2012 to November 2018, a cross-sectional survey was conducted to investigate the prevalence of healthcare-associated infections in hospitalized children for seven consecutive years by combining case-checking and bedside survey.ResultsA total of 10 310 hospitalized children were investigated in the past seven years. The incidence of healthcare-associated infections from 2012 to 2018 was 2.08%, 4.84%, 1.59%, 3.76%, 1.63%, 1.74%, and 2.08%, respectively, showing a statistically significant downward trend (LLA=7.631, P=0.006). The departments with higher proportion of healthcare-associated infections were pediatric surgery (50.0%), pediatric medicine (44.8%), neonatal medicine (2.8%), and intensive care units (2.4%) . Viruses (38.8%) were the most common pathogens of healthcare-associated infections, followed by Gram-negative bacteria (34.3%) .ConclusionsThe prevalence of healthcare-associated infections in the children’s hospital showed a downward trend year by year. Pediatric surgery is the most common occurrence department, and viruses are the most common pathogens. It can provide evidence for prevention and control of healthcare-associated infection in children’s hospitals.
