Objective To investigate the effect of clinical nursing pathway on patients with cerebral infarction. Methods Two hundred patients with cerebral infarction were randomized by random digit table into the clinical pathway group and the conventional nursing group.The former was managed with the clinical nursing pathway and the latter received conventional nursing. The neurologic impairment and the activities of daily life were assessed respectively by national institute of health stroke scale(NIHSS) and Barthel index(BI).The two groups were compared in terms of hospital stay,medical expense,patient’s satisfaction and curative effect. Results Compared to the conventional nursing group,the clinical pathway group was shorter at hospital stay,lower at lower hospitalization cost,higher at patient’s satisfaction and higher in the score by Barthel index,compared to the conventional nursing group(all P<0.05). Conclusion The application of clinical nursing pathway in patients with cerebral infarction can improve the activities of daily living and the quality of care,shorten length of stay,reduce medical cost and increase patients’satisfaction drgree.

Objective To study the effects of malondialdehyde (MDA), superoxide dismutase (SOD) and tumor necrosis factor-? (TNF-?) on brain tissue in rats with pancreatic encephalopathy (PE). MethodsThirty-six Wistar rats were randomly divided into control group (n=6) and PE model group (n=30). In control group, rats were injected with normal saline by internal carotid artery (0.1 ml/100 g) and were killed on the first day after the injection. In PE model group, rats were injected with phospholipases A2 (0.1 ml/100 g, 1 000 U/0.1 ml) by internal carotid artery, to establish animal model of PE in rat and 10 rats were killed on day 1, 3, 7 respectively after the injection. The changes of water content in the brain were measured. Leucocytes aggregation and margination in the microvessels, and the changes of cerebral cells and nerve fibers were observed. The levels of MDA, TNF-? and the activity of SOD were tested in the brain homogenate in rats. ResultsIn PE model group, water contents of brain increased; The phenomena of leucocytes accumulation and margination, cellular edema of neurons and demyelination of nerve fibers became more obvious; The levels of MDA and TNF-? increased significantly than those in the control group, while the activity of SOD reduced (P

Method Two hundred and eighty-nine psychiatric female inpatients from April 2014 to August 2014 were collected, and the reasons of falls cases during this period were analyzed and nursing methods were formulated. Result Nine patients fell, with an incidence of 3.11%(9/289) including the reason of lack of risk dynamic evaluation, lack of fall prevention measures and shortage of nursing personnel. Conclusions The reasons for the falls of the hospitalized psychiatric female patients include lack of risk dynamic evaluation, lack of fall prevention measures, shortage of nursing personnel. The nursing countermeasures include risk assessment of dynamic management and the implementation of the fall prevention measures , strengthening training and health education so as to prevent and reduce the occurrence of falls and ensure patients'safety.

Objective An effective reproducible protocol for complete plant regeneration via somatic embryogenesis has beendeveloped for Herpetospermum pedunculosum,an endangered Tibetan medicinal herb.Methods The cotyledonexplants used in this study were excised from seedlings germinated in vitro.Callus was induced from cotyledonexplants on Murashige and Skoog's medium,supplemented with 2,4-dichlorophenoxyacetic acid(2,4-D,0.1-1.0mg/L)alone or in combination with 6-benzylaminopurine(BA,0.5,1.0,and 2.0 mg/L).Results The calli showeddifferentiation of globular embryos after three weeks of incubation on MS medium supplemented with variouscombinations of BA and NAA.Sixty-two percent of the embryogenic calli produced somatic embryos in MS basalmedium supplemented with BA(1.0 mg/L)+NAA(2.0 mg/L).The addition of KN(0.5 mg/L)to MS mediumcontaining both BA and NAA(2.0 mg/L each)significantly increased the frequency of somatic embryogenesis.Themaximum percentage of embryogenic calli formation was 83%,and globular embryos formed and germinatedsuccessfully in this medium.Then,transferring the regenerated plants from this medium to hormone-free MSmedium will further enhanced the development of the plants,and the healthy plantlets are formed successfullywithin four weeks.The plantlets were transferred to soil to acclimatize under greenhouse conditions and 75%survived.Conclusion Somatic embryogenesis protocol as reported here can play a key role in the propagation andconservation of this endangered species.

A rapid, simple and practical high-performance liquid chromatography method coupled with diode array detector (HPLC–DAD) was developed to evaluate the quality of Alisma orientale (Sam.) Juz. through a simultaneous determination of four major active triterpenes using a single standard to determine the multi-components (SSDMCs). Alisol B 23-acetate was selected as the reference compound for calculating the relative response factors. All calibration curves showed good linearity (R240.9998) within test ranges. RSDs for intra- and inter-day of four analytes were less than 3.6% and 2.3%; the overall recovery was 92.1–110.2%(SSDMC). The proposed method was successfully applied to quantify the four components in 20 samples from different localities in China. Moreover, significant variations were demonstrated in the content of these compounds. In addition, hierarchical clustering analysis (HCA) and principal components analysis (PCA) were performed to differentiate and classify the samples based on the contents of Alisol C 23-acetate, Alisol A, Alisol A 24-acetate and Alisol B 23-acetate. This simple, rapid, low-cost and reliable HPLC–DAD method using SSDMC is suitable for routine quantitative analysis and quality control of A. orientale (Sam.) Juz.

Objective To assess the prevalence, and characteristics, and in-hospital and long-term prognosis of coronary artery disease (CAD) with metabolic syndrome, and to determine the factors affecting the prognosis of CAD most. Method The DESIRE (drug-eluting stent impact on revascularization) registry covered a database of 2368 patients with coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in a period between July 2003 and September 2004. The median long-term follow-up time was 3.5 years ranged from 293 to 1855 days. The metabolic syndrome (MS) was diagnosed on the Definition of the Metabolic Syndrome modified by the Adult Treatment Panel (ATP) Ⅲ in 2005, by using the body mass index (BMI) instead of waist circumference. The relationship between metabolic syndrome (MS) and the incidences of major adverse cardiac as well as cerebral events (MACCE) in a large cohort of patients treated for revascularization was analyzed by using logistic analysis and Cox regression with SPSS 11.0 software. Results The Ms was present in 45.6% patients (high fast glucose (FG) in 44.5% patients, high triglycerides (TG) in 45.0% patients, low high density lipoprotein (HDL) in 50.8% patients, high BP in 61.4% patients, high BMI in60.7% patients). After follow-up, the ratio of MACCE in CAD patients with metabolic syndrome increased significantly (18.9% vs. 15.6%, P <0.036). The most dangerous factors of MS were high FG, hypertension and obesity (OR=1.787, 95%CI=1.132-2.845, P =0.014). Conclusions The MS contributes the high risk factors of MACCE in CAD patients with or without diabetes. The most dangerous combination of risk factors in MS is the combination of high FG, hypertension and obesity.

Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.

Objective To understand the application of drug eluting stent (DES) in renal functional insufficient patients, and to assess its safety and effectiveness, especially the occurrence of stent thrombosis(ST) after DES implantation and its related factors. Methods The subjects were all the patients underwent percutaneous coronary intervention (PCI) as well as at least one DES admitted to Beijing Anzhen Hospital consecutively from July 2003 to June 2005. All patients were divided into 2 groups: Group Ⅰ with normal or mild renal insufficiency (Ccr≥60 ml/min),and Group Ⅱ with moderate to severe renal functional insufficiency (Ccr ＜ 60 ml/min). All of the clinical, angiography and intervention data were recorded. ST was adjudicated by the definition of ARC Dublin. The rates of MACCE in hospital and during the follow-up between the 2 groups were compared. Results There were 2377 patients enrolled in the study, of which 2020 ( 85.0% ) patients presented Ccr ≥ 60 ml/min, and 357( 15.0% ) presented Ccr ＜ 60ml/min. The case fatality during follow-up in group Ⅰ was significantly higher than that in group Ⅱ (4. 5% vs. 1.2%, P ＜ 0. 001 ). However, the incidences of ST were not significantly different between each stage of disease( P ＞0. 05 ). The results from Cox regression showed that renal functional insufficiency was not a risk factor of death,whereas multivessel coronary artery disease [OR = 1. 929(95% CI: 1. 178 -3. 157),P =0. 009] ,diabetes [OR = 1. 914(95% CI:1. 055 -3. 470) ,P =0. 033] and age [OR = 1. 051 (95% CI:1. 005 -1. 099 ) ,P = 0. 030] were independent risk factor of death after DES implantation in patients with moderate to severe renal functional insufficiency. Conclusions Compared with normal renal function or mild renal patients, the longterm case fatality is higher in moderate and severe renal functional insufficiency patients. However, the higher case fatality does not due to the increase of ST.

Objective To evaluate the short-term and long-term outcomes of patients with ST-segment elevation myocardial infarction (STEMI) compared with those with non-STEMI after percutaneous coronary intervention (PCI). Method The DESIRE Ⅱ (Drug-Eluting Stent Impact on Revascularization Ⅱ) was a single-center registered retrospective study of coronary revascularization in our institution between July 2003 and September 2009.Data of demographics, clinical features and revascularization record of STEMI and non-STEMI patients from the DESIRE Ⅱ trial were analyzed. The patients were followed up in OPD or by telephone after discharge. MACCE (major adverse cardiocerebral events) including death, neo-myocardial infarction, stroke and revascularization were recorded. The clinical outcomes of patients of two types were evaluated. Results There were 6005 patients studied with a median follow-up of 566 days. A total of 1009 STEMI and non-STEMI patients were analyzed. The patients with non-STEMI ( n = 206) had higher prevalence of hypertension and history of higher frequency of myocardial infarction as well as revascularization compared with patients with STEMI ( n = 803). The patients with non-STEMI had higher ratio of treatment for multivessel disease (43.7% vs. 34.4%, P = 0.039). There were no significant differences in in-hospital mortality and long-term outcomes (one year survival rate: 96% vs. 98%)between patients with STEMI and non-STEMI. The predictors of 1-year mortality were LVEF and blood creatine.Conclusions Despite different chnical features, patients with STEMI and non-STEMI after PCI had similar both short-term and long-term outcomes.
