OBJECTIVE:To observe the clinical efficacy and safety of edaravone combined with early rehabilitation in the treat-ment of cerebral hemorrhage,and to provide clinical evidence for rehabilitation management and drug treatment of cerebral hemor-rhage patients. METHODS:168 patients with cerebral hemorrhage,collected from neurology department of our hospital during Jan. 2012 to Dec. 2014,were randomly divided into observation group and control group with 84 cases in each group. Both groups re-ceived routine treatment;observation group was additionally given edaravone intravenously on the basis of routine treatment,and be-gan to receive standardized rehabilitation treatment within 48 hours after the onset of symptom;control group began to receive stan-dardized rehabilitation treatment 2 weeks after the onset of symptom. NIHSS and MMSE score of 2 groups were conducted before re-habilitation treatment,and after 4 and 12 weeks of treatment. RESULTS:There was no statistically significant difference in lesion site and clinical manifestations between 2 groups on admission(P>0.05);both NIHSS and MMSE score of observation group were better than those of control group after 4 and 12 weeks of treatment,there was statistical significance(P<0.05). CONCLUSIONS:Edaravone associated with early rehabilitation can obviously improve the prognosis of patients with cerebral hemorrhage.

Aim To investigate the role of Wnt/β-cate-nin signaling pathway on the baicalin-induced osteo-genic differentiation in rat bone marrow derived mesen-chymal stem cells ( rBMSC ) . Methods rBMSC was isolated and cultured by adherence screening method. Alkaline phosphatase ( ALP) amount, CFU-FALP and mineralized nodules were compared between each ba-icalin group and vehicle control group at different time points. Real time q-PCR was employed to evaluate the mRNA level of Wnt signaling-related marker ( Wnt10a, GSK-3β,β-catenin and LEF1) after baica-lin treatment. Protein expression of β-catenin and Runx2 was measured by Western blot. Results Ba-icalin significantly increased ALP activities from day 3 to day 7 . The formation of CFU-FALP and mineralized nodules remarkably increased after rBMSC was treated with1, 10, 50 μmol · L-1 baicalin. mRNA levels of Wnt10a, β-catenin, GSK-3β, LEF1and osteocalcin were enhanced significantly in baicalin-treated group compared to control group. Protein expression of β-catenin and Runx2 was also elevated. Conclusion Baicalin ( 0. 1 to 50 μmol · L-1 ) promotes the osteo-genic differentiation and maturation of rBMSC, in which Wnt/β-catenin signaling pathway might be in-volved.

Objective To explore the effect of the joint edaravone in early rehabilitation on the prognosis of patients with ischemic stroke.Methods The general branch of Kailuan group of patients with ischemic stroke who were conformed to the 1995 national conference on the 4th cerebrovascular diagnostic criteria with head CT or MRI imaging diagnosis,were collected from January 2012 to December 2014.A total of 324 cases were the first onset,who had been treated with conventional drugs,and were randomly divided into the observation group(edaravone associated with early rehabilitation)and the control group(early rehabilitation)with 162 cases in each group.Patients of the observation group were given venous application of edaravone and received the standardized rehabilitation treatment within 48 hours.The control group were given standard rebabilitation therapy at 2 weeks after attacked.NIHSS and MMSE scores of the two groups of patients were evaluated at the beginning of the rehabilitation course,4 weeks and 12 weeks of the treatments.Results There were no statistically significant difference and the clinial manifestations of the lesion site between the two groups of patients on admission.At the beginning of the rehabilitation,the NIHSS and MMSE score of control group were statistically significant different from that of observation group [NIHSS:(14.8 ±5.3)vs.(16.1 ±5.1),PNIHSS =0.049;MMSE:(15.9 ±6.3)vs.(14.2 ±6.2),PMMSE =0.041].The sec-ond and third evaluation were respectively conducted at 4 weeks[NIHSS:(10.1 ±6.3)vs.(8.2 ±5.7),MMSE:(17.7 ±5.5)vs.(20.9 ±5.9)]and 12 weeks[NIHSS:(6.6 ±4.9)vs.(4.7 ±3.6),MMSE:(21.0 ±4.8)vs. (24.6 ±4.9)].The results of the observation group were significantly better than the control group(P4W NIHSS =0.036,P4W MMSE =0.035;P12W NIHSS =0.006,P12W MMSE =0.003),and the differences were statistically significant. Conclusion Edaravone associated with early rehabilitation can obviously improve the prognosis of patients with ischemic stroke.

Objective: To investigate the relationship between long-, short-term systolic blood pressure variability (SBPV) and renal damage in elder population. Methods: Our research was conducted in the 3rd physical examination of healthy population from Kailuan group by cohort study. Cluster sampling was used by 25% ratio in subjects≥60 years of age to monitor their 24-hour ambulatory blood pressure and finally, 2464/3064 participants with inclusion criteria were recruited. SBPV indexes as standard deviation of systolic blood pressure (SSD), variability independent of the mean (VIM), maximum-minimum difference (MMD) and average real variability (ARV) were examined; renal damage indexes as estimated glomerular filtration rate (eGFR) and microalbuminuria (ALBU) were detected. Relationships between different long-term, short-term SBPV indexes and eGFR, ALBU were studied by multi-liner regression analysis. Results:①The mean age of 2464 participants was (67.41 ± 6.05) years including 1667 (67.7%) male and 797 (32.3%) female.②Multi-liner regression analysis indicated that different long-term SBPV indexes were not related to eGFR and ALBU; 24h SBPV in all 4 indexes and day-time SSD, MMD, ARV were negatively related to eGFR; 24h ARV and day-time MMD, ARV were positively related to ALBU; night-time SBPV indexes were not related to eGFR and ALBU.Conclusion: Different short-term SBPV indexes were, at certain point related to eGFR and ALBU

With increasing use of carbapenem antibiotics , carbapenems-resistant gram-negative bacteria are spreading, and carbapenemase-producing is the main mechanism of carbapenems resistance . Rapid and accurate identification of carbapenemase and its type is of great importance to timely and effective treatment and control of infections .Chromogenic /Fluorogenic culture media, modified Hodge test and double disk synergy test are traditional methods for carbapenemase detection , but all are time-consuming. Biochemical method is more time efficient and with high sensitivity and specificity , but cannot be used to identify subtypes.Now matrix-assisted laser desorption ionization -time-of-flight mass spectrometry (MALDI-TOF MS) has been successfully applied in the identification of species , subtypes and detection of drug -resistant genes.And among various carbapenemase gene detection techniques , next generation sequencing (NGS) can also be used for the detection of integrons , transposons and plasmids, which is important in both epidemiology and resistant mechanism studies .This article reviews the advantages and disadvantages of various methods for phenotype and gene detection of carbapenemase .

Objective To explore the risk factors for lower extremity amputation in patients with diabetic foot.Methods The clinical data of 1 771 patients with diabetic foot at the Air Force General Hospital of PLA from November 2001 to April 2015 were retrospectively analyzed.The patients were divided into the non-amputation and amputation groups.Within the amputation group , subjects were further divided into the minor and major amputation subgroups.Binary logistic regression analyses were used to assess the association between risk factors and lower extremity amputation.Results Among 1 771 patients with diabetic foot , 323 of them ( 18.24%) were in the amputation group ( major amputation: 41; minor amputation:282 ) and 1 448 ( 81.76%) in the non-amputation group.Compared with non-amputation patients, those in the amputation group had a longer hospital stay and higher estimated glomerular filtration rate(eGFR)levels.Fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), C-reaction protein (CRP), ESR, ferritin, fibrinogen and WBC levels of the amputation group were higher , while hemoglobin albumin, transferrin, TC, TG, HDL-C and LDL-C were lower than those of the non-amputation group (all P<0.05 ).The proportion of hypertension ( 52.48% vs 59.98%) , peripheral vascular disease ( PAD ) (68.11% vs 25.04%), and coronary heart disease (21.33% vs 28.71%) were different between the amputation and non-amputation groups (all P<0.05).Multivariable logistic regression analyses showed that Wagner′s grade , PAD and CRP were the independent risk factors associated with lower extremity amputation in hospitalized patients with diabetic foot.Conclusion Wagner′s grade, ischemia of lower limbs and infection are closely associated with amputation of diabetic foot patients.
