Delirium is a common complication in elderly inpatients which could result in cognitive impairment, and increase the risk of disability, fall and mortality. Moreover, it could cause heavy social burden. Even with multiple bedside screening scales to detect delirium, the rate of missed diagnosis is still high. Maybe it is associated with the acute fluctuation and nocturnal onset of delirium. With the development of the intelligence and automation of the electronic medical record (EMR), previous studies have explored the use of EMR to identify delirium patients, and this method provides help for delirium diagnosis and prevention. In this paper, we reviewed and summarized the current situation of research on delirium recognition by EMR, and put forward the development prospect in this method in order to provide basis and lay a foundation for intelligent diagnosis of delirium.
Every country has its own clinical guideline to standardize medical care, and China is developing guidehnes too. Viewing the guidehne＇s usage in the world over many years, we find that it hasn＇t achieved good effect. The development of evidence-based medicine brings a primal change to guideline development. The evidence-based clinical guidehnes are arising in the world. We summarized the principle of developing evidence-based guideline according to the experience of Scotland to provide reference for domestic peers.
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 assess the efficacy and safety of Zhiling decoction for vascular dementia. Methods The Specialized Register of the Cochrane Dementia and Cognitive Improvement Group was searched in Feb. 2004 using the term Zhiling. In addition, we handsearched 83 traditional Chinese medicine journals （1993 to 2004 ）. We included all randomized controlled trials（RCTs）of Zhiling decoction treating people with vascular dementia. We also evaluated the internal validity of the RCTs . If all included RCTs were of high quality and homogeneity, then the meta-analysis was conducted. Results Only one RCT was identified. The outcomes were listed as the followings ： ① The Hasegawa＇ s dementia scale scoring （ HDS ） scores of the patients in Zhiling decoction group were improved significantly from baseline after 8 weeks course of treatment and there was no significant difference in the control group. The HDS scores improvement was greater than control group（P 〈0.01 ）o ② The latency of P3 was shorter in both groups after treatment, and there was a significant treatment effect in Zhiling group （t = -52. 09, 95% CI -69.79 to -34.39, P 〈0. 000 01 ）. The amplitude of 173 increased in both groups after treatment, and there was a non-sigmficant treatment effect in Zhiling group for change from baseline （t =1.40, 95% CI -0.02 to 2.82, P =0.05）. ③ Brain electrical activity monitoring （BEAM） showed that benefits in those treated by Zhiling decoction were higher than those treated by Naofukang with OR9.90 （ 95% CI 3.34 to 29.38）. ④In the Zhiling group serum cholesterol （P 〈0.01 ） , serum triglyceride （P 〈0.01 ） and LPO（P 〉0. 01 ） decreased after treatment. There was an increase in the level of high density lipoprotein （HDL） and superoxide dismutase （SOD） in red blood cells compared with baseline for Zhiling groups （P 〈0.01 ）. ⑤ The cerebral blood flow decreased in both groups after treatment, and there was a significant treatment effect in favour of Zhiling （treatment effect t = -1.03, 95% CI -1.26 to -0.80, P 〈0. 00001 ）.⑥ No side effects on heart, liver or renal function were reported in Zhiling decoction group. Conclusions The currendy available evidence is insufficient to assess the potential efficacy for Zhiling decoction in the treatment of vascular dementia. Just one RCT concerning the management of Zhifing decoction versus Naofukang suggests that Zhiling decoction may be effective in treating vascular dementia. Further randomised, double-blind, placebo-controlled trials are urgendy needed .
ObjectivesTo systematically review the efficacy of intra-articular injection of sodium hyaluronate for kashin-beck disease.
MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 1, 2016), CBM, VIP, WanFang Data, and CNKI were electronically searched from inception to January 2016 to collect randomized controlled trials (RCTs) about sodium hyaluronate in the treatment of kashin-beck disease. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software.
ResultsA total of 6 RCTs involving 1 276 patients were included. The result of metaanalysis suggested that the sodium hyaluronate group was significantly superior to the control group in clinical effect (OR=5.89, 95% CI 4.10 to 8.47, P < 0.000 01) and the Lequesne index (SMD=-1.66, 95% CI-2.14 to-1.13, P < 0.000 01).
ConclusionIntra-articular injection of sodium hyaluronate is helpful in the improvement of kashin-beck disease in clinical effect and the Lequesne index. Due to the limited quality and quantity of the included studies, more high quality studies are need to verify the above conclusion.
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.
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.
