To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

The aim of the present study was to investigate the effect of lipoxin A4 (LXA4)pretreatment on cognitive function of aged rats after global cerebral ischemia reperfusion,and to explore its possible mechanism.Thirty-six aged male Sprague-Dawley rats were randomly divided into three groups (n=12 each):sham-operation group (S group),global cerebral ischemia reperfusion group (I/R group) and LXA4-pretreatment group (L group).The rat model of global cerebral ischemia reperfusion was established by occlusion of the bilateral common carotid artery with hypotension.The cognitive function of rats was determined by a step-down type passive avoidance test and Morris Water Maze test on the third day after reperfusion.Rats were sacrificed after Water Maze test and the pathological changes ofhippocampal CA1 region were observed and the related inflammatory mediators were determined.As compared with S group,the escape latency in I/R group was prolonged from the first day to the fifth day,while that in L group was prolonged from the first day to the third day.The retention time in I/R group and L group in the first quadrant was shortened.The reaction time,frequency of reaction mistake and frequency of escape mistake in I/R group increased,and the latent period shortened.The frequency of escape mistake in L group increased,and the damage in the hippocampal CA1 region of I/R group and L group was obvious.The levels of S-100β,TNF-α,IL-lβ,IL-10 and NF-κB in I/R group and L group increased.As compared with I/R group,the escape latency in L group was shortened from the first day to the fifth day,and the retention time in the first quadrant prolonged.The reaction time,frequency of reaction mistake and frequency of escape mistake in L group decreased,and the latent period prolonged.The damage in the hippocampal CA1 region of L group was alleviated as well.The levels of S-100β,TNF-α,IL-1β and NF-κB in L group decreased,and those of IL-10 increased.It can be concluded that LXA4 pretreatment can improve the cognitive function in aged rats after global cerebral ischemia reperfusion probably by inhibiting the inflammatory reaction.

Objective To study the non-fermenter isolation rate and its drug resistance to more than 10 kinds of antibiotics at the First Affiliated Hospital to Xinxiang Medical University from the year of 2010 to 2012 in order to offer evidences for reasonable use of drugs by doctors and to prevent nonfermenters from becoming common pathogenic bacteria.Methods The infection and drug resistance of different Nonfermenters (Pseudomonas aeruginosa,Acinetobacter baumannii,Pseudomon as mahophilia,Los non Acinetobacter,Pseudomonas stutzeri,Achromobacter,Bacillus steady short,onions Bock cepacia,meningitis septicemia Elizabeth Kim bacteria)during present 3 years were analyzed by using WHONET 5.5 software.Results The infection rate from non-fermenters as pathogenic bacteria was gradually increased,with the rate from 18.2％ to 27.2％,until 31.2％ ; Acinetobacter Baumannii were isolated as higher infection rate and multiple drug resistance (7.1％ to 18.5％ until 28.7％) in pathogenic bacteria; the infection rate of other non-fermenter with infection rate of high and multiple drug resistance in pathogenic bacteria were gradually increased,such as infection rate or the precedence of Achromobacter xylosoxidans and Pseudomonas maltophilia,especially the precedence of Pseudomonas maltophilia ranged the third in non-fermenters,and Pseudomonas maltophiliai had a higher and multiple drug resistance to many antibiotics; infection rate of non-fermenters with low drug resistance gradually decreased,such as Pseudomonas fluorescens; the drug resistance rate of Acinetobacter Baumannii was higher than that of Pseudomonas aeruginosa and its drug resistance rate was over 50％ to common antibiotics used clinically,as well as Pseudomonas maltophiliai and Empedobacter brevis,especially the resistance rate of Pseudomonas maltophiliai to many commonly used antibiotics was more than 90.0％.Conclusions Non-fermenter isolation rate is becoming higher clinically and its drug resistance becomes more severe,so the sanitation administration department should pay more attention to the use of antibiotics in order to prevent and control drug resistance and higher infection rate caused by non-fermenters as a serious consequence.

Generation 4 polyamidoamine (PAMAM) dendrimer was PEGylated with polyethylene glycol (PEG) at an average molecular weight 5 000 via amide bond. PAMAM and PEGylated PAMAM (PAMAM-PEG) dendrimer were used as drug nanocarriers. Methotrexate (MTX), an antineoplastic agent, was selected as a model drug. PAMAM/MTX and PAMAM-PEG/MTX complexes were prepared. The pharmacokinetic characters and anti-tumor activity of the PAMAM-PEG/MTX complex were studied as compared with MTX injection and PAMAM/MTX complex by intravenous injection in rats and S180 tumor bearing mice, separately. The plasma samples from normal rats were analyzed by HPLC method, and concentration-time data were analyzed using a non-compartmental analysis. Their anti-tumor effects in vivo were evaluated against S180 solid tumors in mice by measuring average tumor weight and calculating the inhibitory rate of tumor on day 17 after successive injections. The results showed that both plasma half-life and mean retention time (MRT) of the complexes were longer than that of MTX injection (P<0.01), while the area under the plasma concentration vs time curve (AUC) of PAMAM-PEG/MTX was the largest as compared with that of free drug and PAMAM/MTX complex (P<0.01). The inhibitory rate of tumor of PAMAM-PEG/MTX complex enhanced 2.1 and 1.8 times over that of free drug and PAMAM/MTX complex, respectively, indicating that PAMAM-PEG/MTX exhibited the highest antitumor activity. In summary, PEGylated PAMAM could be useful as a potential drug delivery carrier.
