Objective To investigate the therapeutic effect of Ganglioside(GM1) on acute cerebral infarction.Methods 60 cases with acute cerebral infarction were divided into two groups randomly.At the basic of routin treatment for the twe gyoups,GM1 group was treated with GM1 40 mg/d for 14 days and control group was treated with Citicoline 0.75 g/d for 14 days.The neurological deficit scores(NDS),activities of daily living(ADL) and adverse reactions were evaluated.Results After treatment,the scores of NDS and ADL were singnificantly decreased in twe groups than before treatment((P

Objective To investigate the occupational exposures to skin injuries among undergraduate nursing students and analyze the causes,so as to provide advices for the standardized pre-service education of occupational protection.Methods To survey 260 students by simple sampling method using self-made questionnaire retrospectively at the end of the internship.The factors influencing skin injuries were analyzed.Results A total of 238 effective questionnaires were obtained.There were 96.64％ (230/238) practice students suffered skin injuries,the incidence rate was higher at the initial phase.The injuries-risk factors were using hollow needles and glass ampoule,dispensing and back to the set of the needle cap.The preventive measures which the students executed were squeezing out blood,washing with flowing water and sterilizing with iodine and alcohol.Only 58.47％ (473/809) students checked the reports of patients.Most of them were lack of the preventive awareness.Conclusions This study demonstrated that skin injuries occurred frequently among undergraduate nursing students of bachelor degree and their knowledge level about precautions was low.The standard education of pre-service occupational prevention,the occupational exposure post-processing and the reporting system were very necessary.

Objective To compare the characteristics of digital subtraction angiography ( DSA) and compu-ted tomography angiography ( CTA) of moyamoya disease .Methods To analyze the characteristic of DSA and CTA in 29 cases with moyamoya disease ,including arterial occlusion ,arteriarctia,abnormal proliferation of vascular ,collat-eral circulation.Results There were no statistically significant differences between DSA and CTA in detecting arteri-al occlusion,arteriarctia(CTA 53 hemicerebrum,DSA 57 hemicerebrum)(χ2 =2.167,P>0.05),abnormal prolifera-tion of vascular (abnormal:CTA 41 hemicerebrum,DSA 45 hemicerebrum;normal:CTA 16 hemicerebrum,DSA 12 hemicerebrum)(χ2 =0.757,P>0.05).But there was statistically significant difference between DSA and CTA in detecting collateral circulation .Conclusion CTA is a good method to find out moyamoya disease .But DSA is better in discovery collateral circulation of moyamoya disease .

Objective To compare the impact of conventional vs. zero-balanced ultrafiltration on serum pro-inflammatory factors,acute kidney injury and clinical prognosis after cardio-pulmonary bypass procedure. Methods Forty patients receiving cardiac surgery under cardio-pulmonary bypass procedures in Xiangyang Central Hospital during January 2013 to June 2013 were randomly divided into conventional ultrafiltration group(group A,n=20)and zero-balanced ultrafiltration group(group B,n=20). Blood and urine samples were collected on different time points( pre-operation,T0;pre-ultrafiltration,T1;immediately after ultrafiltration,T2;24 hours post-operation,T3;48 hours post-operation,T4;7 days post-operation, T5). TNF-α,IL-6,KIM-1,CysC,serum creatinine and urea nitrogen were detected and compared. Pre-and post-operative clinical data were also collected. Results There was no difference in baseline data or intra-operative data(p>0. 05). TNF-αand IL-6 started to increase when the operation began. Compared with conventional ultrafiltration,zero-balanced ultrafiltration alleviated the increase of TNF-α and IL-6,espe-cially on T2,T3,and T4(p<0. 05). Zero-balanced ultrafiltration also decreased CysC,Rbp,serum creati-nine and urea nitrogen on T2,T3,and T4 compared with conventional ultrafiltration(p<0. 05). A total of 11 patients experienced AKI( >grade I)in group A and 2 patients experienced in group B(p<0. 01). There were significant differences of ventilation time,total complication incidence and ICU stay time be-tween two groups. There was no difference in other complications,post-operative days in hospital or death rate within 30 days. Conclusion Though there is a trend of more patients receving renal replacement therapy,no statistical difference has been achieved. In conclusion,zero-balanced ultrafiltration can effec-tively decrease the concentration of serum pro-inflammatory factors,alleviate acute kidney injury and improve the clinical prognosis after cardio-pulmonary bypass procedures. It is a safe and reliable method valuable for promotion.

OBJECTIVE:To provide reference for the practice of monitoring on adverse drug reactions (ADRs) in secondary or inferior to secondary medical institutions.METHODS:The problems in the practice of ADR monitoring in secondary or inferior to secondary medical institutions were analyzed and the approaches to strengthen the ADR monitoring was discussed taking our hospital as an example.RESULTS & CONCLUSIONS:The problems in the practice of ADR monitoring in secondary or inferior to secondary medical institutions manifested as low general technical level,lacking of advanced information network,hospital leaders' negligence,medical staff's poor consciousness,pharmacy departments' failure in bringing their role into full play,etc.Therefore,it is urgent to attach great importance to the problems to facilitate the development of ADR monitoring by enlarging publicizing,raising awareness;improving the organizational structure and the related working rules,bringing clinical pharmacists and nursing staff's roles into full play and establishing the reward and punishment mechanism,etc.

The methods of separation, enrichment, and analysis of trace mercury in water samples in recent years were reviewed in the present paper. Many methods can be used to analyze trace mercury after separation and enrichment. Spectrophotometry is cheap and simple. Atomic fluorescence spectrometric method is accurate in quantitative analysis. The chromatography method is usually used in the morphological analysis of mercury. Multistep analysis of mercury can be done by joint methods in one time.

Objective: To investigate the relationship between serum uric acid(SUA) and prevalence of hyperuricemia(HUM) and the effects of dietary factors on HUM . Methods: Total 748 subjects from Guangzhou were questioned and SUA and body mass index (BMI) was measured by trained investigators. Results: The mean SUA concentration was (384.6?74.8)mmol/L in males vs (286.3?65.3) mmol/L in females, (P

Aim To establish the technology of isolation rat’s mesenteri c lymphatics and the culture method of their endothelium and confirm the ability o f synthesis nitric oxide and Factor Ⅷ related antigens in the endothelium in vitro. Methods With an operating microscope and microsurgical in struments, rat’s mesenteric lymphatics were isolated and the endothelium were p rimarily cultured and subcultured. Exerting immunohistochemical method, Factor Ⅷ related antigens and nitric oxide synthase were evaluationed. The contents of NO metabolite were measured. Results The rat’s mesenteric lympha tics were isolated and the endothelium were Fusiform shape or polygon, the monol ayer cultures displayed typical cobblestone or pavingstone morphology. Factor Ⅷ related antigens were expressed and their positive rate was 98%. The positive rate of nitric oxide synthase was 83%. Positive reaction products were buffy ar ound nuclear. NO metabolite was (10.26?2.17) mol?L -1(n=7). Conclusion The culture method we introduced was very practical, simple and reliable. The endothelium is in normal structure and function characters. It also certificated that the endothelium in vitro could express nitric oxide synthase and Factor Ⅷ related antigens.

Aging is a biological process and state characterized by morphological change, hypofunction and metabolic disorder, often accompanied by severe degenerative diseases, including amyotrophy, atherosclerosis, neurodegeneration, and so on. Age-related diseases not only decrease the life quality of the elderly, but also impose great burden on family and society. As population aging, we are increasingly coming to realize that the longevity we want should be healthy aging but not simple increase of lifespan. By researching on the yeast, C. elegans, drosophila, mice and humans, we get to know the mechanisms of aging and methods for anti-aging, such as dietary restriction and use of anti-aging drugs like rapamycin. In this review, we summarized mainly the studies on mechanisms of aging and elaborate associated anti-aging strategies and underlying mechanisms.
