Observe and study the morphological changes and effects on yoleperoxidase (MPO) of traditional Chinese medical complex Intestine-clearing Suppository (ICS) in preventing and treating ulcerative colitis (UC).Method.. Divide the experimental rats randomly into 6 groups, i.e., blank, salicylazosulfapyridine (SASP), model, high, middle and low dosage of ICS, except the blank group, makeother rats experimental UC model with albumen immunologic method of rabbit colon mucosa, further divide them randomly into 2 experimental groups, i. e. , prevention and treatment, afterwards at 2nd~21st day, give prevention group the medicine, 22nd~35th day, treatment group, then decapitate them and take the colon tissue, and observe it morphologically under optical microscope, measure active MPO, analyse statastic results. Result: Through general morphological observation ,we found there were serious congestion ,edema, mucosa erosion, many large ulcers in the rats of model group; less serious mucosa erosion and quantity of ulcers in SASP and low-dosage ICS groups: small ulcers, not serious mucosa erosion, low degree of congestion and edema in high-and middle-dosage ICS groups; the scores of inflammatory injury of ICS groups were markedly lower than that of model (P＜0. 01), meanwhile, the preventive and reating effectiveness of high-and middle-dosage groups was better than that of SASP (P＜0.05). Under the optical microscope, there were large area of mucosa coloboma in the rats of model group, the ulcer penetrated to muscular layer and serous coat; in SASP group and low-dosage ICS group, there were erosive mucosa and inflammatory cell infiltration, granulation on the base; in middle-and high-dosage groups, large part of colon mucosa recovered, granulation formed on the base, ulcers were obviously less than that in model group (P <＜0.01); there had marked difference compared with that in SASP group (P＜0.05). The MPO active values of high-and middle-dosage groups were markedly lower than that of model group (P ＜ 0.01). Conclusion: Traditional Chinese complex ICS had good prevention and treatment to rats UC, itseffectiveness was positively correlated with dosage and better than that of SASP suppository.

Objective To study the expression of fascin, an actin bundling protein associated with cell motility, and the relationship with ER negative breast carcinoma.Methods Comparasion of the expression of fascin, estrogen receptor (ER) and proliferative cell nuclear antigen (PCNA) determined by immunohistological method was made on 84 specimens of primary breast carcinomas. Results The diffuse staining of fascin in cancerous cell cytoplasm was noted. Only 3 of 53 breast carcinomas with ER positive showed fascin positive expression (5.67%); in contrast, 21 of 31 carcinomas with ER-negative showed positive expression(67.7 %) (P

Objective To evaluate the effect of dexmedetomidine on lung injury induced by extremity ischemia-reperfusion.Methods Forty patients,aged 18-60 yr,with body mass index of 20-25 kg/m2,of ASA physical status Ⅰ or Ⅱ,with 1 h ≤ predicted duration of surgery ≤ 1.5 h,were randomly divided into 2 groups (n =20 each) using a random number table:control group (group C) and dexmedetomidine group (group D).In groupD,dexmedetomidine 1 (g/kg was infused intravenously for 10 min,followed by continuous infusion of dexmedetomidine at 0.5 μg· kg-1 · h-1 until the end of the surgery,while in group C the equal volume of normal saline was given instead.Immediately before induction of anesthesia (T1,baseline),at 60 min after tourniquet was inflated (T2) and at 30 min,2 h and 6 h after tourniquet release (T3-5),blood samples were collected from the radial artery for blood gas analysis and for measurement of the levels of plasma interleukin-6 (IL-6),IL-8,tumor necrosis factor-α (TNF-α),malondialdehyde (MDA) and superoxide dismutase (SOD),and arterial partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2) were recorded.Alveolar-arterial oxygen difference (A-aDO2) and respiratory index (RI) were calculated.Results Compared with group C,PaO2 was significantly increased at T5,and A-aDO2 and RI at T5,the levels of plasma IL-6 and IL-8 were decreased at T4,5 and the levels of plasma TNF-α,MDA and SOD were decreased at T3-5 in group D.Conclusion Dexmedetomidine can attenuate lung injury induced by extremity ischemia/reperfusion via inhibiting inflammatory responses and lipid peroxidation.

Objective To research the relationship between anaemia and inflammatory in patients with heart failure .Methods 284 cases of patients with heart failure were enrolled and divided into 2 groups (anaemia group and non‐anaemia group) .The serum levels of of brain natriuretic peptide (BNP) ,high‐sensitivity C‐reactive protein (hs‐CRP) ,blood urine nitrogen (BUN) and creati‐nine (Crea) were measured ,and the results were analyzed .Results The levels of BNP ,hs‐CRP and Crea of anaemia group were sig‐nificantly higher than those of non‐anaemic group (P<0 .01) .The results of logistic regression demonstrated that hs‐CRP was in‐dependently associated with anaemia (P=0 .021) .Conclusion The occurrence and development of inflammation are independently associated with anaemia in the patients with heart failure .

Objective To investigate the correlation of HIF-1α and hypoxia in keloids fibroblasts, and to investigate the mechanism that hypoxia promotes abnormal scarring by HIF-1α pathway. Methods Keloid fibroblasts cultured in vitro were placed in an incubator with different O2 concentrations. After 24 h, the keloid fibroblasts were collected for further study. Western blotting was performed to detect the expression of HIF-1α in the keloid fibroblasts. Results Relative amounts of HIF-1α in keloid fibroblasts cultured under O2 concentrations at 20 %, 10 %, 5 % and 1 % were 0. 007 ±0. 006, 0. 133 ±0. 006, 0. 537±0. 015 and 0. 903±0. 021, respectively. It indicated that hypoxia could increase the expression of HIF-lα in keloid fibroblasts. Conclusions Hypoxia can induce the expression of HIF-1α in fibroblasts of keloids. Moreover, there still is a positive relation between hypoxia and the expression of HIF-1α. Therefore, a close relationship exists between abnormal scarring and HIF-1α pathway by hypoxia.

Objective To observe the initial therapy outcomes of Valproic acid for childhood absence epilepsy (CAE),and to assess its therapeutic reaction and short-term prognosis,and to investigate the risk factors for initial therapy failure.Methods From January 2010 to December 2015,absence seizures as key words were used to search CAE in the video-electroencephalogram(VEEG) database of Children's Hospital Affiliated to Nanjing Medical University.Sixty-seven children fulfilled the CAE diagnosis criteria of International League Against Epilepsy in 1989.These patients were separated into 2 groups based on the therapy outcome after 6 months,including seizure control failure group and seizure control group.The patients' clinical characteristics and VEEG characteristics were reviewed.The gender,age of seizure onset,a family history of epilepsy or febrile seizures (FS),consistent with 2005 Panayiotopoulos diagnostic criteria,and VEEG findings were analyzed to evaluate the predictive ability of independent variables and the relationship between these features and treatment outcomes by using a stepwise multivariate Logistic regression model.Results The age at seizure onset was (5.89 ± 2.91) years old,and follow up duration was 6 months.Approximately 23 cases (34.3％) of CAE patients had poor response.No statistical correlation was made for gender,age at onset,the occurrence of generalized tonic clonic seizures,and family history of FS or epilepsy between 2 groups (all P ＞0.05).Compared with seizure control group,patients of the seizure control failure group had significantly higher rates of focal epileptic discharge (87.0％ vs.6.8％),higher rates of intermittent photic stimulation (IPS) induced seizures (52.2％ vs.6.8 ％),fewer rates of occipital intermittent delta activity (8.7 ％ vs.77.3 ％),and fewer rates of patients met the new diagnostic criteria proposed by Panayiotopoulos in 2005 (8.7％ vs.88.6％) (all P ＜ 0.001).The presence of occipital intermittent rhythmic delta activity during wake stage and the interictal focal epileptiform discharges on VEEG during sleep stage were significantly associated with the therapy outcomes in a multivariable Logistic regression analysis (OR =133.714,P ＜ 0.05;OR =0.068,P ＜ 0.05).Conclusions The presence of focal epileptiform discharges,and a typical absence induced by IPS are important factors for first-drug treatment failures with CAE,and conversely the occipital intermittent rhythmic delta activities have a good efficacy.There is no statistical correlation between clinical characteristics and treatment outcomes.

AIM: To study the neuroprotective effect and possible mechanism of ganglioside GM 1 on neonatal hypoxic-ischemic-encephalopathy(HIE). METHODS: A rat model of neonatal HIE was established, then the pathological changes and expressions of nitric oxide synthase (NOS) in the brain tissues were investigated in different periods after hypoxia-ischemia (HI) and the subseqent changes of the above results after GM 1 administrated. RESULTS: The damage of the brain exposed to HI were alleviated significantly after GM 1 administrated. The levels of NOS expressions in the brain tissue increased after HI. GM 1 could inhibit NOS expressions induced by HI. CONCLUSION: GM 1 may have some protective effects on neonatal HIE, and the possible mechanism is related to the partial inhibition of NOS expression.
