Stomach cancer is a malignancy arising from the stomach mucous epithelium. It accounts for 95% of all stomach malignancy cancer. The prevalence of stomach cancer is high in China and the treatment is debated, especially regarding choice of chemotherapy and treatment duration. In order to identify the best treatment and follow-up for patient with stage T2N0M0 stomach sinus cancer, we searched MEDLINE, SUMsearch, The Cochrane Library (Issue 4, 2004), Clinical Evidence (Issue 4, 2003) and CBMdisc (1981 to 2004). A total of 3 systematic reviews, 28 randomized controlled trails, 3 cohort studies and 3 observational studies were identified. We evaluated the quality of included studies.All studies were divided into 5 grades by the levels and grades of recommendation. We drew a conclusion by synthesizing the results of included studies: The primary treatment for the patient was surgery treatment including gastric deuto-total resection and D1 lymph node dissection. There was no evidence supporting chemotherapy use in either systematic or abdominal cavity after surgery. The survival rate was high in 5 years and 10 years, so the follow-up time should not be long and the follow-up infermission should not less than 1 year. Follow-up included the dynamic and delayed MR sequence with Gd-DTPA, the level of serum CA199, endoscope, and stool occult blood test.
Objectives To assess the efficacy and safety of statins for adult osteoporosis. Methods We electronically searched The Cochrane Library (Issue 4, 2007), MEDLINE (1990 to November 2007), EMBASE (1990 to November 2007), Current Controlled Trials, The National Research Register, CBM (1990 to November 2007), VIP (1990 to November 2007) and CNKI (1990 to November 2007). We also handsearched some related journals and identified randomized controlled trials of statins versus placebo in adults with osteoporosis. Results Two randomized controlled trials were included. We didn’t perform meta-analysis due to heterogeneity. No significant differences were observed in the changes of bone density at the lumbar spine and total hip from baseline between statins and placebo. However, a significant increase in bone density was found in response to simvastatin at the forearm. Biochemical markers of bone metabolism changes from baseline did not differ significantly between statins and placebo groups. Conclusions The evidence currently available does not support the use of statins in the treatment of osteoporosis. Further randomized, double-blind, placebo-controlled trials are needed in order to define the efficacy and acceptability of statins in the treatment of osteoporosis.
Objective To determine whether statins has some effects on the treatment of cardio-cerebral vascular diseases or hyperlipdemia increases bone mineral density （BMD）. Methods One hundred and sixty-two patients aged over 60 were identified in the outpatient-department of Geriatrics of West China Hospital from Jan. 1998 to Aug. 2003. Seventy cases were exposed to statins with follow-up for 5 years. BMD of the spine, femoral neck, femoral wards triangle and femoral trochanter was measured by dual-energy X-ray absorptiometry. The multiple regression analysis was used to exclude potential confounders, e.g. age, BMI, comorbidity,etc. Results Those elderly patients with a history of taking statins had higher BMD, such as femoral neck with t =-2. 466 （P =0. 015）, femoral wards triangle with t =-2. 483 （P = 0. 014 ）and femoral trochanter with t =-2. 743 （P =0. 007 ）than the control elderly at the end of follow-up. Conclusions It has been found that HMG-CoA reductase inhibitors （statins ） may prevent bone loss in elderly patients by increasing BMD. Further prospective studies of statins are needed to confirm these observatioris.
ObjectiveTo analyze and reduce the defects in nursing records for blood transfusion by continuous quality improvement (CQI) method, in order to prevent blood transfusion related medical disputes. MethodsIn October 2014, CQI team was established to analyze the reason for transfusion record defects and make standardized process and quality monitoring forms for nursing record of blood transfusion. Six months after the implementation of CQI, 40 records were randomly selected before the CQI implementation (April to September 2014) and after the implementation (April to September 2015) for comparison and analysis. ResultAfter 6 months of implementation of CQI, nursing record defects of blood transfusion decreased significantly from 228 to 55 items. ConclusionUsing CQI method can effectively reduce nursing record defects of blood transfusion. CQI can also improve the quality of nursing records and prevent medical disputes caused by blood transfusion.
Rheumatoid arthritis is a chronic inflammatory disorder. It is characterized by a chronic polyarthritis that primarily affects the peripheral joints and related periarticular tissues. To a patient with rheumatoid arthritis, we searched the evidence and indentified the best available therapy for him: ① Ibuprofen was used to relieve pain. ② Methopterin ivgtt qw and oral methopterin after the discharge for 12 months. ③ Oral omeprazole 20 mg/d to prevent peptic ulcear. ④ Administration with fish oil and physical exercises after discharge were recommended.
Objective To report evidence-based treatment for 2 case of Ⅱ B stage non-small cell lung cancer. Methods We searched systematic reviews and randomized controlled trials in The Cochrane Library (Issue 2, 2009), MEDLINE (PubMed, January 1970 to June 2009) and ACP Journal Club (1996 to June 2009), and evaluated the evidence. Results The best clinical evidence for Ⅰ and Ⅱ stage non-small cell lung cancer patients showed that in the patients with resectable nonsmall cell lung cancer, postoperative adjuvant radiotherapy and chemotherapy could not improve survival compared with surgery alone. We did not find evidence which indicated that preoperative chemotherapy improved survival in people with resectable non-small cell lung cancer. Conclusion In accordance with the wishes of the patient and family, they do not accept the radiotherapy and chemotherapy, but choose palliative and supportive therapy.
