Objective To investigate the patient’s psychological anticipation and occurrence of chemotherapy-induced nausea and vomiting (CINV), and to assess the influence of CINV on quality of life, so as to provide evidence for clinical doctors to recognize and pay attention to CINV. Methods The patients in the Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology who took either moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC) were randomly sampled with a questionnaire for two circles. Patients were asked to record the following indexes before chemotherapy, on the second day and the sixth day of chemotherapy: acute and delayed nausea and vomiting, independently taking antiemetics, and functional living index-emesis (FLIE). Then, descriptive analysis and multiple linear regression analysis were adopted for the outcomes of investigation. Results A total of 344 patients were investigated, of which 303 fulfilled the questionnaire finally. For the single-day chemotherapy, the acute nausea and vomiting, delayed nausea vomiting and overall complete remission in the MEC group were 86.1%, 76.6%, and 71.5%, respectively; while those of the HEC group were 84.1%, 71.0%, and 66.7%, respectively. For the multi-day chemotherapy, the acute nausea and vomiting, delayed nausea vomiting and overall complete remission were 93.8%, 64.9%, and 64.9%, respectively. Patients’ expectation of nausea and anticipatory anxiety was closely related to the delayed nausea in their prior circle of chemotherapy. Based on the FLIE assessment, about 30% of all patients reported reduced daily living function. Conclusion CINV remains a significant problem among patients in China, especially in controlling the reaction during delayed phase and nausea as well. It requires that more attention should be paid to CINV and more effective prophylaxis should be adopted in clinical practice.
【Abstract】Objective To introduce the birth and development of model of endstage liver disease (MELD) and evaluate its effect on liver transplantation(LT) as a new scoring system. Methods Literatures of MELD applied in LT were analyzed retrospectively. Results MELD scoring system was used for predicting the prognosis of patients with endstage liver disease and the death risk of candidates on waiting LT extensively and the order of organ sharing was determined by its predicable results. Conclusion MELD has been had a successful initial implementation for predicting the shortterm survival probability and mortality in patients with endstage liver disease, and meeting the goal of providing a system of allocation that emphasizes the urgency of the candidate while diminishing the reliance on waiting time, which has been proven to be a powerful tool for auditing the liver allocation system.
ObjectiveTo develop and modify a rat model of partial liver transplantation with hepatic arterialization and to investigate the postoperative histopathologic changes of the grafts. MethodsModified twocuff technique was applied to establish a rat model of partial liver transplantation, and the donor’s celiac artery was anastomosed with the recipient’s right renal artery. The biopsy of the grafts was performed on the day 1,2,4 and 7 after transplantation. Results85.4% of the recipients had survived for one week.Nuclear mitoses were seen on the postoperative day 2 by microscopy, while on the day 4 they were found occasionally. Two nucleus cells were seen on the day 4 and 7. Conclusion The stability of the model is improved by modifying the technique. Liver acupuncture biopsy is a simple, safe and feasible way to be applied in the research of postoperative problems of liver transplantation. Reconstruction of hepatic artery is possible to enhance the regeneration of liver grafts.
Objective To establish a new model on isolated human cadaver testes with ischemiareperfusion (I/R). MethodsThirteen isolated cadaver testes contributed by 13 persons were preserved under 0℃-4℃ hypothermia and then reperfused under 37℃. Histological and histochemical changes were observed. Results4℃ cold ischemia in 12 hours induced only trivial swelling and vascular degeneration of endothelial cells (ECs), obvious pathologic changes occurred after 24 hours, including detachment of ECs, separation between basement membrane and seminiferous epithelium, degeneration and detachment of spermatogenous cell and edema of mesenchyme. Injury was worse along with the prolongation of cold preservation time. Changes of LDH and SDH activities were found by histochemical staining. Reperfusion following 6 hours ischemia induced tissue injury and unusual enzyme activity. All changes were more obvious after reperfusion following 12,18,24 or 36 hours cold ischemia.Conclusion This new model on isolated cadaver testes with ischemiareperfusion is successful, it can substitute other solid organs of human beings for I/R injury study.
Objective To clarify the most important factors affecting the survival of patient with gastric carcinoma. Methods 428 cases of resected gastric carcinoma were studied by using univariate analyses and multivariate regression analyses. Results The most significant factors influencing survival of these patients were peritoneal dissemination, Borrmann classification, type of operation, hepatic metastasis, size of tumor, location, lymph node metastasis and age. Conclusion The factors influencing survival in patient with gastric carcinoma after resection can be correctly analyzed by cox’s proportional hazard model.
Liver transplantation in hamster-to-rat is a good model for the research in xenograft, but it is difficult to be performed. In order to simplify its procedures, 38 cases of liver transplantation in hamster-to-rat were performed with several technique improvments on the basis of orthotopic liver transplantation in rats. In the light of hamster’s anatomy, three cuffs anastomosis method was used. Because of its high stability and high survival rate, the model can be used widely as the research for liver xenograft.
A acute partial obstructive hepatocholangitis model by selective ligation and injection of E coli into left hepatic bile duct was successfully founded in rat. Using parameters including mortality, mitochondrial glutamic oxalacetic transaminase and ornithine carbamoytransferase activity, pathological observation and blood culture of bacteria, we evaluated the model. The authors emphasize that this models is superior to the wole-bile-duct-challenged cholangitis model, which is characterized by liver injury.
We have performed guided chemoembolization on 84 patients of moderate and advanced carcinoma of liver using adriamycin lipiodol emulsion (A/L) since 1986. Result showed that the rate of improvement of symptoms was 86.1%, in 75% cases the AFP were decreased and in 79.2% the size of tumor were reduced. The mean survival time was 10.3 months which was much higher than that of the control group (5.6 months,Plt;0.001). THe survival rates of 1/2,1,2,3 year were 89.3%,43.4%,13.5% and 3.8% respctively that were significantly higher than those of the control group (51.2%, 11.5%,0) (Plt;0.01). Three patients underwent secondary resection after using A/L chemoembolization ans gelatin spinge central embolization with a longer survival rate. This may be a good method of treatment to the nonresectable liver cancers and may also be an easy way for postoperative observation.
Abstract: Objectives To evaluate the accuracy of four existing risk stratification models including the Society of Thoracic Surgeons(STS) 2008 Cardiac Surgery Risk Models for Coronary Artery Bypass Grafting (CABG), the European System for Cardiac Operative Risk Evaluation (EuroSCORE), the American College of Cardiology/American Heart Association (ACC/AHA) model, and the initial Parsonnet’s score in predicting early deaths of Chinese patients after CABG procedure. Methods We collected clinical records of 1 559 consecutive patients who had undergone isolated CABG in the Fu WaiHospital from November 2006 to December 2007. There were 264 females (16.93%) and 1 295 males (83.06%) with an average age of 60.87±9.06 years. Early death was defined as death inhospital or within 30 days after CABG. Calibration was assessed by the Hosmer-Lemeshow (H-L) test, and discrimination was assessed by the receiveroperatingcharacteristic (ROC) curve. The endpoint was early death. Results Sixteen patients(1.03%) died early after the operation. STS and ACC/AHA models had a good calibration in predicting the number of early deaths for the whole group(STS: 12.06 deaths, 95% confidence interval(CI) 5.28 to 18.85; ACC/[CM(159mm]AHA:20.67deaths, 95%CI 11.82 to 29.52 ), While EuroSCORE and Parsonnet models overestimated the number of early deaths for the whole group(EuroSCORE:36.44 deaths,95%CI 24.75 to 48.14;Parsonnet:43.87 deaths,95%CI 31.07 to 56.67). For the divided groups, STS model had a good calibration of prediction(χ2=11.46, Pgt;0.1),while the other 3 models showed poor calibration(EuroSCORE:χ2=22.07,Plt;0.005;ACC/AHA:χ2=28.85,Plt;0.005;Parsonnet:χ2=26.74,Plt;0.005).All the four models showed poor discrimination with area under the ROC curve lower than 0.8. Conclusion The STS model may be a potential appropriate choice for Chinese patients undergoing isolated CABG procedure.
Objective To report an acute ischemic left ventricular heart failure model of safe, simple, relatively steady, and reproducible in sheep. Methods Fourteen female sheep with a body weight of 36.80±3.43kg were used in this study. Heart failure model was induced by partial occluding the middle left circumflex coronary artery (LCX) combined with pacemaker-induced tachycardia. Hemodynamic measurement was done before and after heart failure, myocardial examination was observed. Results Heart failure model was induced successfully in 10 sheep. Cardiac output dropped from 3.74±0.48L/min to 2.02±0. 51L/min (P〈0. 01), mean arterial pressure decreased from 116. 10± 14.15 mmHg(1kPa = 7.5mmHg) to 68. 10± 14. 72mmHg (P〈0.01), central venous pressure rose from 7. 10±2.18mmHg to 10. 70± 3.50 mmHg (P〈0.05), right ventricular end-diastolic pressure increased from 6.10±3.57mmHg to 9.90±4.41mmHg(P〈0.05), left atrial pressure increased from 8.10±2.13 mmHg to 12.00± 4.57mmHg (P〈0. 01 ), and left ventricular end-diastolic pressure increased from 8. 50± 4. 17mmHg to 13.10± 10. 64mmHg(P〉 0. 05). The myocardial ultrastructure injuries was marked. Conclusions Acute ischemic left ventricular heart failure could be induced by partial occlusion of the middle LCX combined with pacemaker-induced taehyeardia in sheep. This model is simple, easy to manipulate, relatively steady, and reproducible . It may be used for assessing cardiac assist devices.
