Objective To build new management model for diabetic foot disease,and to observe the therapeutic effect of diabetic foot ulcers under the new model.Methods 52 patients with newly diagnosed diabetic foot disease were recruited and randomly divided into the experimental group (n=26) and the control group (n=26).While the experimental group adopted the interdisciplinary collaboration model (nurse-doctor jointed diabetes care management model),the control group were treated by the single department pattern.The foot ulcer healing rate,average length of stay (ALOS),fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PBG),glycosylated hemoglobin (HbA1c),and the patient awareness of the knowledge about diabetes self-management were respectively compared at 3 and 6 months.Results After receiving a multidisciplinary joint diagnosis and treatment,FPG and 2 h PBG of the patients from the experimental group [(6.44±2.93)mmol/L,(8.52± 2.09)mmol/L] were significantly decreased than those of the patients from the control group [(8.17±3.19)mmol/L,(10.77±3.27)mmol/L].HbA1c at 3 and 6 months (7.2％,7.7％) and ulcer recurrence rate (3.8％) after 6 months of patients of the experimental group were significantly reduced than those of the control group(8.9％,9.1％ and 15.4％).When compared with patients of the control group,patients of varying severity in the experimental group showed significantly shortened ulcer healing time and hospital stay.Moreover,patients from the experimental group showed statistically higher knowledge level and self management ability (P＜0.05).Conclusion Through interdisciplinary collaboration,podiatric medical joint management model can significantly improve cure rate,shorten ALOS,improve blood sugar control and patient satisfaction.

Objective To investigate the risk factors of pneumonia in patients with non ST segment elevation-acute cononary syndromes (NSTE-ACS).Methods A total of 183 cases with NSTE-ACS was divided into pneumonia and non-pneumonia groups.The possible risk factors were screened firstly,then nonconditional logistic model multivariate analysis was used to investigate risk factors including age,sex,weight,smoking,chronic obstructive pulmonary disease (COPD),hypertention,diabetes,left ventricular failure,renal failure,low serum albumin,early revascularization and early rehabilitation exercise on the occurrence of pneumonia in NSTE-ACS.Results The differences were statistically significant in factors including age,smoking,COPD,diabetes,left ventricular failure,renal failure,low serum albumin,early revascularization,and early rehabilitation exercise between two groups (P ＜ 0.05).By analysis of logistic,risk factors on the occurrence of pneumonia in NSTE-ACS were age,smoking,COPD,diabetes,left ventricular failure,renal failure,and low serum albumin(P ＜0.05).Early revascularization and early rehabilitation exercise were the protective factors to avoid pneumonia.Conclusions Left ventricular failure,age,smoking,COPD,diabetes,renal failure,and low serum albumin were the risk factors of pneumonia occurred in NSTE-ACS,but early revascularization and early rehabilitation exercise were the protective factors to avoid pneumonia.Actively treating the risk factors and early initiating the protective factors can effectively reduce the incidence of pneumonia.

Esophageal variceal bleeding is a severe complication of cirrhotic portal hypertension and the main cause of mortality in patients. Studies revealed no significant differences in emergency hemostasis rate,fatality rate,and rebleeding rate between patients receiving endo-scopic treatment and vasoactive agents.The advances in emergency management of esophageal variceal bleeding,including endoscopic band ligation,sclerotherapy,and use of vasoactive agents,are reviewed,with emphasis on emergency endoscopic treatment and drug therapy for esophageal variceal bleeding.

Objective To promote rational drug use by investigating quality of the outpatient and emergency prescriptions in the hospital .Methods We statistically summarized the evaluations of prescriptions and analyzed the drug use from January to Novem-ber ,2012 .Results The outpatient and emergency prescriptions were compliant to relevant writing standards ,without missing i-tems .The inaptitude of prescriptions were mainly in forms of inappropriate indication ,usage ,and dosage of drug and menstruum . The irrational prescriptions accounted for 5 .5% of those evaluated .Conclusion Rational drug use has been basically ensured through implementation of prescription evaluations and interventions .Irrational prescriptions exist in relatively small scale and are to be eliminated .

Parkinson’ s disease ( PD) is a neurodegenerative disorder primarily characterized by resting tremor, muscular rigidity, akinesia and postural reflex impairment.Behavioral tests of PD in animal models are essential for under-standing the pathogenesis of PD as well as for the development and testing of potential therapeutics .Here we mainly use the 6-hydroxydopamine (6-OHDA)-induced rat model, to introduce a review on the research progress in non-drug-induced be-havioral tests of motor function in PD rats.

Isocitrate dehydrogenases(IDHs)are considered as key enzymes in the tricarboxylic acid cycle. Recurrent mutations in the IDH1 and IDH2 genes are recently found in several human cancers. Those point mutations specifically affect IDH1 and IDH2 active site arginine residues and confer a neomorphic enzyme function of directly catalyzing α-ketoglutarate(α-KG)to R-2-hydroxyglutarate(R-2-HG). R-2-HG can com-petitively inhibits α-KG-dependent enzymes and may therefore contribute to the occurrence and development of tumor. In addition,Mutation status of IDH1 and IDH2 are closely relative to the progress and prognosis of cer-tain tumor. Thus IDH1 and IDH2 are considered to be promising biomarkers for early diagnosis and prognosis and targeted therapy.

Objective To investigate the relationships between serum inflammatory mediators and myocardial injury in rats with sepsis.Methods Thirty male Sprague Dawley (SD) rats were randomly divided into normal control group and sepsis (0,24,48,72 h) groups.The rats subjected to sepsis were induced with cecum ligation perforation (CLP).Tumor necrosis factor alpha (TNF-α),interleukin-6 (IL-6),cardiac troponin Ⅰ (cTnI) and B-type natriuretic peptide precursor (NT-proBNP) in the venous blood were measured at 0 h,24 h,48 h,and 72 h after CLP.The lactic acid (Lac) of the arterial blood,cardiac index (CI),acute physiology and chronic health evaluation (APACHE) Ⅱ score were also determined simultaneously.Results The levels of TNF-α,IL-6,cTnI,NT-proBNP,and Lac in sepsis (24 h,48 h,and 72 h) groups were significantly elevated compared to normal control and sepsis (0 h) group.In addition,the number of sepsis (24 h,48 h,and 72 h) groups progressively increased (P ＜0.05).Conclusions It existed a close relationship between serum inflammatory mediators and myocardial injury,and made myocardium damage after CLP.

Objective To investigate the significance of peroxisome proliferator-activated receptor (PPAR)γexpression in the lung tissue of rats with chronic hypoxic pulmonary hypertension (HPAH). Methods Forty male Sprague-Dawley rats were randomly divided into four groups (n=10 for each group):normal control group (NC), hypoxia control group-one-week (HC-1w), hypoxia control group-two-week (HC-2w) and hypoxia control group-three-week (HC-3w). Normal control group was raised under normal oxygen condition in ventilated animal cage for three weeks. The other HC groups were placed in a low oxygen chamber (O2 concentration of 10%) from 9:00 AM-5:00 PM (8 h/d) everyday by one week, two weeks and three weeks. The mean pulmonary arterial pressure (mPAP), right ventricular systolic pressure (RVSP) were detected. The index of right ventricular hypertrophy RV/(LV+S) was measured by dissecting rat heart. The morphological changes of the small pul-monary arteries were observed by HE staining, and the percentage of vascular wall thickness (WT%) was calculated. The ex-pression level of PPARγprotein was detected by Westren blot assay. Results The mPAP, RVSP and RV/(LV+S) were sig-nificantly higher in HC groups than those of NC group (P<0.05). The morphology of pulmonary arteries showed vessel wall thickening and vessel lumina stenosis in HC groups compared with that of NC group. The PPARγexpression in lung tissue was significantly lower in HC groups than that of NC group, and the downward trend was more obvious with the extension of time. Conclusion PPARγplays an important role in the occurrence and development of chronic hypoxic pulmonary hyper-tension.

Allergic rhinitis (AR)and bronchial asthma often coexist in the same individual,in which they influence development and severity of each other.Both domestic and foreign research has showed that Syn-ergistic treatment to children with AR and asthma could be achieved by inhaled corticosteroids(ICS),oral leu-kotriene receptor antagonist and subcutaneous /sublingual allergen specific immunotherapy;collaborative manage-ment will be realized by doctors'Comprehensive clinical assessment,children and caregivers'self-assessment and chronic disease management tools.Collaborative treatment and management is significant to children with both allergic rhinitis and asthma.In addition,it has an edge in improving compliance of children and their parents during the treatment,the quality of childrens'life,and reducing burden of the diseases.
