Objective Methods of evidence-based medicine were used to make an individulized treatment plan concerning newly diagnosed type 2 diabetes mellitus in elderly patients. Method After clinical problems were put forward, evidence was collected from third issue, 2003, Cochrane Library, Medline (PubMed 1990.1-2003.2) and http:// sumsearch.uthscsa.edu/ searchform4.htm according to the search strategy. Subject words were: diabetes mellitus non-insulin-dependent; self-monitor of blood glucose; micro-and macro-vascular complications; sulphonylureas; insulin ; aspirin; metformin; acarbose; self-monitor of blood glucose; older patient; hypertension management; Lipid management; RCT; human; meta-analysis；systmatic review. Results A total of 112 RCTs, and 24 systematic reviews were identified. A rational treatment plan was made upon a serious evaluation of the data. After one year follow-up, the plan was proved optimal. Conclusions The treatment efficacy in newly diagnosed type 2 diabetes mellitus in the elderly has been improved by determining an individulized treatment plan according to evidence-based methods.
Objective To formulate an evidence-based treatment for a patient newly diagnosed with follicular lymphoma. Methods Based on the clinical questions we raised, evidence including systematic reviews and randomized controlled trials was collected from ACP Journal Club (1991 to November 2007), The Cochrane Library (Issue 4, 2007) and PubMed. The retrieved studies were further critically appraised. Results The addition of rituximab to chemotherapy (R-chemo) was superior to chemotherapy alone in patients with follicular lymphoma. The regimen of CVP chemotherapy plus rituximab (R-CVP) was administered to the patient. After 4 courses of R-CVP, the patient had a complete response (CR). Conclusion In newly diagnosed patients with follicular lymphoma, R-chemo is an effective treatment regimen.
Objective To identify the best therapy regime for dyspnea in an end-stage cancer patient.Method We searched The Cochrane Library (Issue 2, 2006), SUMsearch (1978 to 2006) and MEDLINE (1978 to 2006), and identified 4 systematic reviews and 28 randomised controlled trials. We critically assessed the quality of these studies. Result Evidence supported the use of breathing exercise, desensitisation, oral or parenteral opioids and antianxiety drugs to pall iate breathlessness. Patients with hypoxemia were found to benefit from oxygen therapy. Conclusions Physiotherapy, psychotherapy, oxygen therapy, opioids and antianxiety drugs can be considered in treating cancer patients with dyspnea.
Objective To report an evidence-based treatment of Mycophenolate Mofetil for idiopathic membranous nephropathy (IMN) with nephrotic syndrome (NS). Methods We searched The Cochrane Library (Issue 3, 2005), MEDLINE (1978 to 2006) and CNKI (1978 to 2006), and critically appraised the available evidence. Results The available Level C (low quality) evidence showed that Mycophenolate Mofetil was effective for the remission of proteinuria, and effective in patients who were resistant to steroid or cytotoxic agents. However, there was no evidence on its long-term effect on renal survival. Given the current evidence, together with our clinical experience and the patient’s preference, Mycophenolate Mofetil and glucocorticoid were administered to the patient. After 3 months of treatment, proteinuria was relieved. The patient is still can followed up. Conclusions We only find Level C evidence to support the short-term efficacy of Mycophenolate Mofetil on the remission of proteinuria. Further studies on its long-term effects on renal survival, and a health economics evaluation are needed.
Objective We searched for evidence on mycophenolate mofetil(MMF) as a treatment for patients with diffuse proliferative lupus nephritis. Methods We attempted to find the current best evidence by searching The Cochrane Library(Issue 4, 2005), MEDLINE(1990 to June 2007), CMB(1980 to December 2006), CNKI(1979 to October 2007). We critically appraised the available evidence. Results Four systematic reviews and 6 randomized controlled trials of high quality were available. MMF and prednisolone were found to be an effective continuous induction-maintenance treatment for diffuse proliferative lupus nephritis. MMF was associated with less drug toxicity. Conclusion Given the current evidence and our clinical experience, and considering the patient and the values and preferences of his family,MMF was given at 1 g daily in combination with steroids at the beginning. No obvious adverse effects occurred during 3 months of follow-up.
Objective To formulate an evidence-based treatment plan for a patient with advanced hepatocellular carcinoma. Methods The clinical problems were put forward after full evaluation of patient’s conditions, and then the evidence related to the diagnosis and treatment of primary hepatocellular carcinoma was collected from The Cochrane Library (Issue 4, 2010), PubMed (1980 to 2010), Embase (1990 to 2010) and Wanfang Data (1990 to 2010). All the collected evidence was critically assessed. Both patient preferences and physician clinical experience were also taken into consideration in the decision-making treatment. Results A total of 153 relevant literatures were detected, and 13 meta-analyses or systematic reviews, 23 RCTs and 4 practice guidelines were identified. A rational treatment plan was made upon a serious evaluation of the data and the opinion of the patient. After a 6-month follow-up, the plan proved to be optimal. Conclusion The individualized treatment plan according to evidence-based methods for patients with advanced hepatocellular carcinoma can effectively improve the therapeutic efficacy and the life quality.
Objective Methods of evidence-based medicine were used to make an individualized treatment plan concerning newly diagnosed diffuse large-B-cell lymphoma in elderly patients. Methods After clinical problems were put forward, evidence was collected from MEDLINE (Jan. 1990 to Dec. 2004) and http://sumsearch.uthscsa.edu/searchform4.htm. Subject words were: NHL; aggressive non-Hodgkin’s lymphoma; diffuse large-B-cell lymphoma; chemotherapy; CHOP; rituximab; RCT; economic evaluation; older patient. Results A total of 11 randomized controlled trials and 8 systematic reviews about chemotherapy regimen, and 1 systematic review about economic evaluation were identified. A rational treatment plan was made upon a critical evaluation of the data. After 5 months follow-up, the plan was proved optimal. Conclusions The treatment effectiveness in newly diagnosed diffuse large-B-cell lymphoma in the elderly has been improved by an individual treatment plan according to evidence-based methods.
Objective To formulate an evidence-based nursing scheme of eye care for an unconscious patient undergoing mechanical ventilation with eye complication. Methods Under the principle of PICO, the issue was put forward aiming directly at patient’s clinical manifestations, and the following databases as The Cochrane Library (Issue 12, 2011), PubMed (January 1980 to November 2011), EMbase (1974 to 2011) and CBM (1978 to 2011) were searched. Results A total of 3 guidelines, 2 systematic reviews and 9 randomized controlled trials (RCTs) were included. The evidence showed that eye cleaning was the very important part of eye care, and the commonly-used cleaning or rinsing solutions were saline and sterile water. Both moist cover and lubricating eye drops / ointment were used to prevent dryness in the eyes. For instance, polyethylene moisture covers could effectively prevent corneal abrasion, and lubricating eye drops / ointment were beneficial to eye observation, so these two methods needed to be properly selected in combination with patient’s conditions. Nurses had to assess the ability of the patient to close eyelids daily and helped the patient to close eyes, but the passive eyelids closure was inferior to the artificial tear ointment in the effect on preventing corneal abrasions; the integrated intervention of maintaining eyelids closure and forming eyeballs moisture chamber was more effective to prevent eye complications. According to the available evidence mentioned herein and the patient’s conditions, the following nursing scheme of eye care was formulated: cleaning the eyelids and peripheral skin using 0.9% saline gauze, covering the eyes with sterile polyethylene films which were fixed by anti-allergic adhesive tapes, changing the dressing every 12 hours, and observing closure of the eyelids every day. Seven days later, eye symptoms got obviously improved, with decreasing secretion, without congestion and chemosis, and negative results of fluorescein staining test. Conclusion Eye cleaning removes secretion and bacteria from the eyes. Polyethylene film prevents tear from evaporation and fully promotes the immune function of tears which can reduce the risk of infection. Eyelids closure and local moisture environment benefit the corneal epithelial repair.

Objective To make individualized evidence-based treatment for patients with diabetic nephropathy with albuminuria. Methods Based on the clinical questions we raised, evidence was collected and critically assessed. Patients’ willingness was also taken into consideration in the decision-making treatment Results Seventy studies were retrieved and finally 14 randomized controlled trials, 2 systematic reviews, 2 meta-analyses and 41 clinical guidelines were considered eligible. The evidence indicated that albuminuria was an independent cardiovascular risk factor of diabetic patients; angiotensin receptor antagonists might decrease the level of urinary albumin excretion in patients with type 2 diabetic nephropathy; and such patients might benefit from blood glucose and blood pressure control. The individualized treatment plans were developed based on the available evidence. After 1 month of treatment, the serum creatinine returned to normal and albuminuria became negative. Conclusion The individualized treatment plans based on the high quality evidence were optimal in reducing cardiovascular complications and urinary albumin excretion. However, long-term prognostic benefits need to be confirmed by further follow-up.
