Objective To investigate the association between serum uric acid (SUA)levels and outcome in acute ischemic stroke.Methods A total of 388 acute ischemic stroke patients were included in the prospective case study.Data on demographic characteristics, risk factors for life style, history of disease, the admission SUA and outcome at discharge were collected for all participants.Results Mean serum uric acid levels were (284.5±83.6) μmol/L in the normal uric acid? group, and(455.3±78.1)μmol/L in the high uric acid group(P＜0.01).There were significant differences in National Institutes of Health Stroke Scale (NIHSS) score at two weeks between the high UA group and the normal UA group [(11.0±6.0) vs.(11.0±5.3),P=0.048], and also in early neurological improvement (P=0.048).A significant difference was found in serum uric acid level between patients with good versus poor neurological function outcome (P =0.045).Conclusions There is the association between admission serum uric acid levels and outcome in acute ischemic stroke.Elevated serum uric acid level predicts a lower chance of a poor outcome in acute ischemic stroke.

Objective To explore the pathogenic bacteria and immunologic mechanism of recurrent respiratory tract infection(RRI) in children.Methods The observation group included 50 children with RRI,26 cases were boys and 24 cases were girls, in Department of Respiratory Medicine of Wuhan Children′s Hospital were enrolled from Apr.2007 to Apr.2008.These children were divided into 3 subset groups:28 cases in 6 months-2 years old group,15 cases in 3-5 years old group,and 7 cases in 6-12 years old group.The healthy control group included 50 healthy children aged 6 months -12 years.The specimens were gathered on the next morning after the children entered hospital.The secretions of noses and pharynxes were gathered with clean and aseptic tampon from children with upper respiratory tract infection and placed in aseptic vessel,and were immediately detected with the pathogenic bacteria.The secretions of lower respiratory tract were gathered with suction method from children with lower respiratory tract infection and placed in aseptic vessel, and were immediately detected with the pathogenic bacteria,the number of superinfection with some kind of pathogenic bacteria was calculated.The children in observation group and healthy control group were exsanguinated of vein when the children were hungry to detect the cellular immunity(CD3+,CD4+,CD8+,CD4+/CD8+) and humoral immunity(IgA,IgM,IgG,C3,C4).Results Three hundred and two specimens in 6 months-2 years old group were detected,and 135 pathogenic bacteria were separated,the ratio of positive was 42.2%,and the number of superinfection was 25.One hundred and thirty-seven specimens in 3-5 years old group were detected,and 47 pathogenic bacteria were separated,the ratio of positive was 34.3%,and the number of superinfection was 7.Fifty-four specimens in 6-12 years old group were detected,and 16 pathogenic bacteria were separated,the ratio of positive was 29.6%,and the number of superinfection was 2.The top 5 kinds of bacteria that those children with RRI were easily infected were Ps.aeruginosa,K.pneumoniae,S.aurens,E.coli and streptococcus pneumoniae.The CD3+,CD8+ and CD4+/CD8+ of cellular immunity in the observation group were obviously lower than those in the healthy control group(Pa

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

Objective To explore the effect of comprehensively-designed experiment teaching methodology in the teaching of geriatric nursing. Methods Sixty-three nursing students in the grade of 2010 were assigned into the experiment group, where the comprehensively-designed experiment teaching methodology were adopted. And the fifty-eight nursing students in the grade of 2009 were assigned as the control group, where the traditional experiment teaching methods were adopted. The two groups were compared in terms of theory test scores and evaluations to the two teaching methods. Result The theory examination score and students'evaluation in the experiment were higher than those of the control group (P<0.05). Conclusion Comprehensively-designed experiment teaching method used in the teaching of geriatric nursing is beneficial for the students to improve their interest in learning, cultivate their comprehensive quality, shorten the gap between the experimental teaching and clinical practice and improve the teaching effect of geriatric nursing.

Objective To summarize the complications of the single-port transumbilical laparoscopic pyeloureteroplasty.Methods From August 2009 to December 2014, 162 surgical procedures were performed in our institute with the single-port transumbilical laparoscopic pyeloureteroplasty.Medical records of each procedure were retrospectively evaluated.139 patients were male and 23 female, aged from 1 month to 14 years and the median age of 2 years.127 patients were operated on the left side and 32 on the right side.3 patients were operated on the bilateral side.All children were supplemented with preoperative ultrasound, renal dynamic imaging and MRU to identify the ureteropelvic junction obstruction.Intraoperative and postoperative complications were graded according to the Satava and Clavien classifications respectively.Major complications were defined as Satava grade Ⅱ or higher, and Clavien grade Ⅲ or higher.Results There was no injury of vascular or visceral organs and no blood transfusion, and there was no serious intraoperative complications.One hundred and forty-three cases were followed up, and 23 cases (16.1％)presented with postoperative fever (＞ 38 ℃C) (Clavien Ⅰ), 2 cases (1.4％) with urinary extravasation diagnosed by perirenal fluid collection(Clavien Ⅰ).All these cases recovered after being given symptomatic treatment.7 cases (4.9％) presented with postoperative repeated urinary infection (Clavien Ⅱ).5 cases received postoperative reoperation due to the obstruction of the anastomic site (Clavien Ⅲ b), and 2 cases were under debridement as the greater omentum was drawn out along with the negative pressure drainage tube(Clavien Ⅲ a).In summary, the incidence of severe postoperative complications was 4.9％.Conclusions Though there existed some postoperative complications of the single-port transumbilical laparoscopic pyeloureteroplasty, the incidence of serious complications was low and the overall prognosis could be good.

Objective To improve the poor water-solubility of nimodipine,nimodipine-loaded PLEG copoly- met nanopartieles were prepared to avoid the sedimentation of its crystal from water,which could also shun the blood vessel stimulation caused by ethanol,a cosolvent,in the injection.Methods Solvent evaporation method was used to prepare water-dispersing nimodipine-loaded nanoparticles,whose lyophilized powder was further prepared,with PLEG2000 as drug carrier.Particle size,Zeta potential,embedding ratio,drug loading,shape and redispersion ability of the lyophilized powder were determined.Results Concerning the lyophilized nanoparticle powders,the particle sizes were 136nm,the Zeta potentials were -29.90mV,the embedding ratio was 67.9% and the drug loading was 6.17%.Conclusion Prepared nimodipine-loaded nanoparticles solved the problem of poor water-solubility of ni- modipine basically.It also avoided the recrystallization process of the drug and reduced the blood vessel stimulation caused by ethanol in the injection.
