  • The Alteration of Plasma Calcitonin Gene Related Peptide Level During Thrombolytic Therapy in Patients with Iliofemoral Venous Thrombosis

    ObjectiveTo probe plasma calcitonin gene related peptide (CGRP) levels during thrombolytic therapy in patients with iliofemoral venous thrombosis in order to investigate its regularity of the alteration and its clinical significance.MethodsFifty patients with acute iliofemoral venous thrombosis and 30 patients with chronic iliofemoral venous thrombosis were given urokinase and prostaglandin E1 from veins for 15 days. The CGRP levels were determined by radioimmunoassay before treatment and on the 6th hour, 1st day, 3rd day, 7th day, 14th day, 30th day after treatment.ResultsThe plasma CGRP levels were increased in patients with acute iliofemoral venous thrombosis compared with the contrast ones. The CGRP levels in serious group was lower than those in mild group. However, the CGRP levels of 30 chronic patients and 12 patients who received the second course of thrombolysis as on effective were not different from those of contrast ones. The plasma CGRP levels were increased at the 6th hour,reached the peak at the 3th day and returned to normal at the 14th day after thrombolytic therapy in acute group which just consistent with the therapeutic effectiveness.ConclusionIt is helpful to judge whether the thrombolytic therapy is effective and the illness has come to chronic stage according to the levels of plasma CGRP in patients with iliofemoral venous thrombosis.

  • Effects of Haemopoietic Stem Cell Mobilization on Improving Vein Graft Patency

    Abstract: Objective To investigate the effects of haemopoietic stem cell mobilization on vein graft patency and intimal hyperplasia of anastomosis. Methods Twentyfour New Zealand rabbits were randomly divided into experimental group and control group, 12 rabbits in each group. A double side of carotid arteryvein transplantation model was made in each rabbit. One side of vein graft was digested by 0.25% trypsin for complete endothelial denudation before transplantation. Recombinant human granulocyte colonystimulating factor was given by subcutaneous injection 24 hours after operation, once per day in successive 10 days in experimental group, saline was given in the same way in control group. Bone marrow stem cells mobilization was observed after operation, including karyote counts and mononuclear cell proportion in peripheral blood. The patency rate of vein grafts and the degree of anastomosis intimal hyperplasia were observed too. Results The karyote counts (t=8.406,P=0.000)and mononuclear cell proportion(t=31.267,P=0.000) in peripheral blood of experimental group increased significantly 5 days after operation than those in control group. The vein grafts with intact endothelium had higher patency rate in both groups. In the vein grafts with complete endothelial denudation, the patency rate were obviously lower, but it was higher in experimental group than those in control group (67% vs. 30%). In the end of experiment, the pulsatility index of the vein grafts anastomosis with complete endothelial denudation was lower in experimental group than that in control group(t=2.958,P=0.009). Pathological examination showed that various degrees of intimal hyperplasia in all anastomoses of vein grafts were observed 4 weeks after operation. The degree of anastomosis intimal hyperplasia was more severe in vein grafts with complete endothelial denudation. Compared with control group, re-endothelization occurred completely in vein grafts with complete endothelial denudation of experimental group and the degree of anastomosis intimal hyperplasia was relatively lower (Plt;0.05). Conclusion Haemopoietic stem cell mobilization can provide protective effects on vein grafts by accelerating reendothelization which might increase vein grafts patency rate in the near future after operation and reduce anastomosis restenosis caused by intimal hyperplasia.

  • Reflections under Evidence-Based Medicine on the Intervention Clinical Research Designs

    Although the evidence from randomized controlled trials (RCTs) is regarded as a golden standard, it often fails to be applied in clinical practice for lack of generalizability. Evidence from either RCTs or non-RCTs is mutually complementary and referred. Different designs are suitable for different stages and can resolve different issues. During evaluation of an intervention, the proper research design should be selected in accordance with the objective, feasibility, and merits and limitations of different design modes.

  • Current status of research on models for predicting acute kidney injury following cardiac surgery

    Acute kidney injury (AKI) is a complication with high morbidity and mortality after cardiac surgery. In order to predict the incidence of AKI after cardiac surgery, many risk prediction models have been established worldwide. We made a detailed introduction to the composing features, clinical application and predictive capability of 14 commonly used models. Among the 14 risk prediction models, age, congestive heart failure, hypertension, left ventricular ejection fraction, diabetes, cardiac valve surgery, coronary artery bypass grafting (CABG) combined with cardiac valve surgery, emergency surgery, preoperative creatinine, preoperative estimated glomerular filtration rate (eGFR), preoperative New York Heart Association (NYHA) score>Ⅱ, previous cardiac surgery, cadiopulmonary bypass (CPB) time and low cardiac output syndrome (LCOS) are included in many risks prediction models (>3 times). In comparison to Mehta and SRI models, Cleveland risk prediction model shows the best discrimination for the prediction of renal replacement therapy (RRT)-AKI and AKI in the European. However, in Chinese population, the predictive ability of the above three risk prediction models for RRT-AKI and AKI is poor.

  • Effectiveness of probiotics for prevention of ventilator-associated pneumonia: a systematic review

    ObjectiveTo systematically evaluate the efficacy and safety of probiotics for prevention of ventilator-associated pneumonia (VAP).MethodsThe Web of Science, Pubmed, OVID, Cochrane Library, CNKI, EMbase, Sciencedirect, Chinese biomedical database, and Wanfang database before August 2017 were searched, and the relevant data resources were also searched by hand to collect randomized controlled trials (RCTs) of probiotics for prevention of VAP. The quality of the included studies was evaluated using a modified version of the Jadad scale. Meta-analysis was performed with RevMan 5.3 software.ResultsA total of 16 RCTs were included. The use of probiotics can reduce the incidence of VAP [RR=0.71, 95%CI (0.62, 0.80), P<0.000 01], ICU days [MD=–3.28, 95%CI (–6.15, –0.41), P=0.03] and total duration of antibiotics [MD=–2.47, 95%CI (–4.89, –0.04), P=0.05], but can not reduce the mortality of ICU [RR=0.99, 95%CI (0.74, 1.32), P=0.94], hospital mortality [RR=0.77, 95%CI (0.58, 1.01), P=0.06], 28-day mortality [RR=1.01, 95%CI (0.69, 1.47), P=0.97], 90-day mortality [RR=1.00, 95%CI (0.72, 1.37), P=0.99], hospital stays [MD=–0.68, 95%CI (–3.88, 2.52), P=0.68], duration of mechanical ventilation [MD=–2.17, 95%CI (–4.78, 0.44), P=0.10], or the incidence of diarrhea [RR=0.96, 95%CI (0.80, 1.14), P=0.62]. No serious adverse events were reported in all included RCTs.ConclusionsThe use of probiotics can reduce the incidence of VAP, but it has no effect on the mortality, hospital stay, duration of mechanical ventilation or the incidence of diarrhea. However, considering the heterogeneity of research designs, we need more rigorous, large sample randomized controlled studies to increase the strength of evidence.

  • Preliminary therapeutic effect of tile shape perineal stapled prolapse resection in treatment of rectal prolapse

    Objective To evaluate therapeutic effect of tile shape perineal stapled prolapse resection in treatment of rectal prolapse. Methods The clinical data of 31 patients with rectal prolapse underwent tile shape perineal stapled prolapse resection in the Renmin Hospital of Wuhan University from December 2013 to August 2015 were retrospectively analyzed. All the patients with rectal prolapse were performed the tile shape perineal stapled prolapse resection with general anesthesia and (or) epidural anesthesia. The prolapse was completely pulled out and then axially cut open with a linear stapler in the lithotomy position. Finally, the prolapse was resected stepwise with the curved stapler at the prolapse’s uptake. Results There were 8 males and 23 females in the 31 patients. The age was (65.8±3.2) years old. There were 14 patients with Ⅱ degree and 17 patients with Ⅲ degree prolapses. The median course was 5.8 years. The 31 patients were followed up for 0.5–7.0 months. Of 31 cases, the 24 cases were cured and 7 cases were better. It was found out that there was a significant difference between the number of axially cut open with a linear stapler and the weight of specimen (P<0.05). And there was a significant difference between the number of axially cut open with a linear stapler and the recurrence (P<0.05) too. When the number of axially cut open with a linear stapler were 4 for Ⅱ degree and 3 for Ⅲ degree, the treatment had been proved to be the highest efficacy. Conclusions Preliminary results of limited cases in this study show that tile shape perineal stapled prolapse resection is safe and effective in treatment of rectal prolapsed. Key of operation is that prolapse is completely pulled out and then axially cut open with a linear stapler at some o’clock for 2–4 points and rectal valves are formed. Prolapsed is resected stepwise with curved stapler at prolapse’s uptake. When number of axially cut open with a linear stapler are 4 for Ⅱ degree and 3 for Ⅲ degree, it could achieve the best therapeutic effect.
