Objective:To investigate the protective effect of rifampicin in a rat model of global cerebral ischemia /reperfusion ( GCIR) and discuss the influence of rifampicin on microglial activation.Methods:The GCIR rat model was induced via the bilateral occlusion of the common carotid arteries and systemic hypotension.Forty-two male SD (Sprague-Dawley) rats were randomly assigned to three groups:sham group ,I/R and I/R+FRP treated group.The rats in I/R+RFP group were treated with rifampicin 20 mg/kg by intra-peritoneal injection 30 min after reperfusion , while the other groups were treated with normal saline.Morris water maze test was performed for neurobehavioral test ,HE staining was detected for pathomorphology changes of neurons in CA 1 region.Microglia was im-munohistochemically stained in CA 1 region using ionized calcium adaptive molecular 1 ( IBA-1) as the marker.The protein levels of IL-1β,IL-6 and TNF-αin the hippocampal tissues of rats were also measured by enzyme-linked immunosorbent assay.Results:Rifampin improved the behavior ,shorten the escape latency of rats following GCIR obviously ( P<0.05 ) and reduced the neuron damage in hipp-ocampal CA1 region of rats after GCIR (P<0.05).Additionally,in I/R+FRP treated group the activation of microglia also showed a significantly inhibited compared with I/R group(P<0.05).Futhermore,we also found the expression of IL-1β,IL-6 and TNF-αin hipp-ocampal reduced obviously in I/R+FRP group ( P<0.05 ).Conclusion: Rifampin have obvious protective effect in the rat model of GCIR.The underlying mechanism may be associated with inhibition the activation of microglia ,reduction the expression of IL-1β,IL-6 and TNF-αand suppression the inflammatory response finally.

Objective To explore the predictivevalue of Wilms tumor gene 1 (WT1) level on long-term outcome of acute myeloid leukemia(AML).Methods The study in accordance with the inclusion criteria were collected by computer retrieving PubMed,ScienceDirect,EBSCO,Web of Science,CNKI,VIP and Wan Fang database.The retrieval time was from inception to March 2015,the two researchers according to the inclusion and exclusion independently selected studies and extracted the data and assessed the quality,then Revman 5.2 was used for Meta analysis.Results There were 11 relevant published articles were included with 1497 case patients.Meta analysis showed that High expression of WT1 gene was a negative factor for overall survival rate (OS) and disease free survival (DFS) in patients with AML (HR =1.34,95％CI 1.14-1.58,P ＜ 0.01;HR =1.35,95％CI 1.11-1.64,P =0.003).For cytogenetically normal AML patients,the high expression of WT1 gene was still the unfavorable factor of OS (HR =1.41,95％ CI 1.01-1.99,P =0.05).Conclusion WT1 expression level could be an useful prognosis long-term outcome marker for AML patients.

Objective To evaluate the clinical and pathological features of eosinophilic cystitis (EC),and to discuss its diagnosis and treatment.Methods The clinical and pathological data of one case of eosinophilic cystitis were reported.An 86-year-old male with gross hematuria and urinary urgency for 15 days was admitted on 16 March 2015.A computed tomography scan showed uneven thickening of the bladder wall and a nodular soft tissue on the anterior wall protruding into the bladder cavity.Results Cystoscopic examination showed diffuse thickening of the bladder with polypoid red lesions on the anterior wall.Transurethral biopsies revealed infiltrating eosinophils,which was consistent with the diagnosis of EC.The patient was then treated with anti-inflammatory drugs,corticosteroids and anti-histamine drugs.At 6 months of follow-up,the patient was asymptomatic and had no evidence of local recurrence by ultrasonography.Conclusions Eosinophilic cystitis is a rare disease without specific clinical and imaging features,which can mimic bladder tumor.The final diagnosis of this disease depends on the pathology.Transurethral resection of the lesion along with postoperative hormone and antihistamines administration are the main choices of treatment.

Objective To study the relationship between cardiovascular diseases (CVD) and ischemia modified albumin (IMA) in patients with type 2 diabetes mellitus (T2DM).Methods Ninety-six patients with T2DM were selected as T2DM group retrospectively,and 60 cases of healthy physical examination were selected as control group,the patient' s medical history data were collected,the IMA was detected and Doppler ultrasound examination was performed.The relationship between serum IMA level and some laboratory parameters were analyzed.Results Twenty-eight cases (29.2％,28/96) occurred CVD among 96 cases of T2DM patients.The level of IMA in T2DM group was higher than that in control group [(58.25 ± 11.84) kU/L vs.(23.38 ± 6.41) kU/L],there was significant difference (P ＜ 0.05).The levels of IMA in T2DM combined with CVD group (28 cases) and T2DM not combined with CVD group (68 cases) were(91.46 ± 13.63),(47.91 ± 9.38) kU/L; the level of IMA in T2DM combined with CVD group was higher than that in T2DM not combined with CVD group and control group,there was significant difference (P ＜ 0.05).All patients completed echocardiography,Spearman correlation analysis between IMA and echocardiography indicators showed that the level of IMA was positively correlated with left ventricular end-diastolic diameter (r =0.546,P =0.031),interventricular septal thickness (r =0.427,P =0.039),posterior wall diameter of left ventricle at end-diastolic (r =0.582,P =0.026) and left venifieular mass index (r =0.339,P =0.042),and IMA was negatively correlated with ejection fraction of left ventricle (r =-0.561,P =0.024).Multivariable Logistic regression analysis showed that IMA,high-sensitivity C reactive protein,diabetes duration,fasting blood glucose levels were independent risk factors for CVD.Conclusions Serum IMA level is significantly higher in T2DM patients.IMA level is a related risk factor for CVD.

Objective To investigate the correlation between homocysteine(Hcy) and atheroscIerosis (AS) in type 2 diabetic patients.Methods A total of 98 type 2 diabetic patients in Donghua Hospital Affiliated to Sun Yet-Sen University were enrolled in this study and served as diabetic group.Meanwhile diabetic patients were divided into aged group(aged ＞65 years old) and young and middle aged group(＜65 years old).Fortynine healthy volunteers were used as control group.Intima-media thickness(IMT) and atherosclerotic plaqlles of the extracranial common carotid artery were detected by high-resolution B-mode ultrasoograph.Fasting plasma glucose (FPG),postprandial 2 h glucose (2 hPG),glycosylated hemoglobin (HbA1 c),total cholesterol (TC),total triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),creactive protein(CRP) and Hcy were measured.Correlation analysis of Hcy and IMT with other parameters was performed.Results Hcy level in patients with type 2 diabetes were (34.15 ± 10.25) μmol/L,significantly higher than those in healthy control group((8.46 ± 3.62) μmol/L,P =0.014).Hcy level in age group((40.63 ± 11.78) μmol/L) was significantly higher than that of young and middle aged group((26.54 ±9.38) μmol/L,P =0.028).IMT value and plaque detection rate in elderly patients were (1.28 ±0.26) mm and 66.1％ (20/41),significantly higher than that in the young and middle aged group((1.02 ±0.20) mm and 38.9％,P =0.041,0.027).Multiple stepwise regression analysis showed that age (OR =1.46,95％ CI:1.18-6.36,P =0.029),duration of diabetes (OR =2.62,95％ CI:1.78-7.43,P ＜ 0.001),LDL-C (OR =1.54,95％CI 1.19-6.27,P =0.028),CRP(OR =1.38,95％ CI 1.11-4.84,P =0.032),Hcy(OR =2.45,95％ CI 1.34-6.61,P =0.018)) were independent risk factors for carotid AS.Conclusion The Hcy level significantly increase in type 2 diabetic patients.Hcy,age,duration of diabetes,LDL-C,CRP are independently risk factors of neck AS.

Objective To investigate the distribution relationship of microglia and neuron in rat medullary visceral zone(MVZ) after stomatic nociception. Methods After 2ml formalin(2.5%)injection in rat stomach by tiny plastic tube,Anti-Fos protein(labeling neuron)and anti-OX 42(labeling microglia)single and double immunohistochemical ABC method staining on model medulla oblongata sections in different time point(0.5h,1h,2h and 3h) were used. Results 1.After wakefulness,the animal models appear restlessness and agitation in 1-2h.2.We found hemorrhage and exfoliation in model's gastric mucosa.3.Fos positive neurons and OX 42 positive microglias were observed in MVZ,whose distribution was congruous and appeared clearly character of locations.4.The results of immunochemical diplex staining indicate that many Fos positive neurons were surrounded by intensive OX 42positive microglias.5.OX 42 positive microglia showed a tendency,which increased in 0.5-2h and decreased in 3h.Conclusion Neurons and microglia in MVZ may be involved in visceral nociception transfer and adjustment function.

OBJECTIVE To investigate the relationship of resistance and ?-lactamases of Acinetobacter baumannii.METHODS The bacteria cultured were identified with API 20NE system.The susceptibilities of the bacteria were detected by disk diffusion method.The ?-lactamases produced by these strains were characterized by three-dimensional test and 2-mercaptopropionic acid inhibition assays.RESULTS In 150 strains,the resistant rates of strains were 4.0% to cefoperazone/sulbactam.The resistant rates to imipenem,meropenem,piperacillin/tazobactam,ampicillin/sulbactam and levofloxacin were between 20.0% and 55.0%.The resistant rates to ceftazidime,cefepime,aztreonam and amikacin were above 60.0%.Three-dimensional test showed that 37 strains(24.7%) produced extended spectrum ?-lactamases(ESBLs),66 strains(44.0%)produced AmpC enzymes and 16 strains(10.7%)produced carbapenemases,in which 12 strains(8.0%) produced metallo-?-lactamases.CONCLUSIONS The resistant rates of A.baumannii to routine antibiotics are high except cefoperazone/sulbactam and carbapenem.It is the most important reason for multi-drug resistance that the strains of A.baumannii produce ESBLs,AmpC enzymes and metallo-?-lactamases.

Objective To know the impact of nursing intervention mode of parent-child interactive on the adaption of postpartum family roles.Methods One hundred families (maternal,husbands,baby at birth) were divided into the intervention group and the control group.The intervention group was cared by the responsibility nurses who were trained to master the parent-child interactive nursing intervention.The control group was cared by conventional nursing methods.The role adaptation of the fathers and the mothers of the two groups,and self-confidence of the parents to take care of newborns were observed.Results In the intervention group,the role adaptation of the fathers and the mothers was better than the control group; self-confidence of taking care of the newborn was better than the control group.The sleep time of the newborns was prolonged and the crying times were less than the control group.Conclusions The parent-child interactive nursing intervention model can help the family to adapt to the father and the mother role as soon as possible; teach the parents to comprehensively understand newborns,give stimulation of touch,sight,hearing,smell,so as to achieve positive response of newborns and increase the confidence of rearing newborns of the parents.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.

OBJECTIVETo compare the therapeutic effect of Astragalus and Angelica Mixture (AAM) on treating CKD patients according to different CKD primary diseases, staging and TCM syndromes.

METHODSA multicentre, open-label, and self control clinical design was used, and thirty-two patients in line with inclusive criteria were recruited. Based on maintaining their previous basic CKD treatment, patients additionally took AAM (Astragalus and Angelica each 30 g), once a day, three months consisted of one therapeutic course. Serum creatinine (SCr), estimated glomerular filtration rate (eG- FR), 24 h urinary total protein (UTP), plasma albumin (ALB), hemoglobin (Hb), and changes of TCM syndrome factor integrals were compared before treatment, at the end of month 1, 2, and 3. The differences in the aforesaid indices were compared between CKD patients with different CKD primary diseases (chronic glomerulonephritis, chronic renal tubulointerstitial disease, hypertensive renal damage), different CKD stages (CKD 3 and CKD 4), and patients of qi-blood deficiency syndrome (QBDS) and non-QBDS.

RESULTSAAM could improve 78.12% (25/32) patients' renal function. Compared with before treatment, SCr decreased (12.08% +/- 10.11%), eGFR increased (21.14% +/- 18.55%), and ALB increased (2.76% +/- 1.97%) at the end of 3-month treatment (all P < 0.05). As for TCM syndrome factor integrals, compared with before treatment, the integrals for qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome decreased, while the integrals for dampness heat syndrome and turbid-toxin syndrome increased (all P < 0.05). There was no obvious difference in all indices except the integral for hypertensive renal damage patients of yin deficiency syndrome (P > 0.05). The SCr decreasing percent was 19.82% +/- 8.30% for patients of non-QBDS and 5.24% +/- 10.75% for patients of QBDS. The latter was higher with statistical difference (P < 0.05). As for TCM syndrome factor integrals, the integral differences of qi deficiency and blood deficiency were obviously higher in patients of QBDS, when compared with patients of non-QBDS (P < 0.05).

CONCLUSIONAAM could improve the renal function of CKD patients, elevate their ALB levels, and ameliorate associated qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome, especially for CKD patients of QBDS.
