ObjectiveTo investigate the effect of mild hypothermia on neuron specific enolase (NSE) and superoxide dismutase (SOD) in serum of patients with large-area cerebral infarction.Methods160 cases with large-area cerebral infarction were divided into the treatment group and control group with 80 cases in each group. Patients of the control group were treated with routine therapy. Those of the treatment group were added with mild hypothermia therapy (MHT). The scores of NIHSS were assessed and NSE and SOD in serum were examined before treatment and 7, 14 and 30 days after treatment in two groups.ResultsThe NIHSS score of the treatment group was significantly lower than that of the control group ( P<0.05), and NSE level decreased, SOD vitality increased in the treatment group. Other indexes such as respiratory, pulse, serum kalium and etc of two groups were not different ( P>0.05).ConclusionMHT can improve he nerve function of patients with large-area cerebral infarction recovering and improve prognosis.

Objective To evaluate the effect of electric vagal stimulation on myocardial ischemia-reperfu-sion (I/R) injury in rats.Methods Forty-five male Sprague-Dawley rats,aged 4-5 months,weighing 180-220 g,were randomly divided into 3 groups (n =15 each):sham operation group (S group),I/R group,electric vagal stimulation group (EVS group).Myocardial I/R was induced by occlusion of left anterior descending branch of coronary artery for 30 min followed by 120 min reperfusion in I/R and EVS groups.In group EVS,the left cervical vagus nerve trank was stimulated for 30 min with continuous electric pulses (5 V,2 ms,10 Hz) starting from 10 min before reperfusion until 10 min of reperfusion.The animals were sacrificed at the end of 120 min reperfusion and the hearts were removed for determination of the infarct size,TNF-α and IL-6 contents and myeloperoxidase (MPO) activity in myocardial tissues.Results Compared with group S,the infarct size was significantly enlarged,and TNF-α and IL-6 contents and MPO activity were increased in I/R and EVS groups (P ＜ 0.05).The infarct size was significantly smaller,TNF-α and IL-6 contents and MPO activity were lower in EVS group than in I/R group (P ＜ 0.05).Conclusion Electric vagal stimulation can reduce myocardial I/R injury in rats and activation of cholinergic anti-inflammatory pathway is involved in the mechanism.

0.05).CONCLUSIONS There is high frequency of C.albicans in the elderly.There is no significant difference rate of detection rate among three groups.Mucosa swab sampling method may be a convenient and effective method for clinical study.

This paper is aimed to study the differences of allelopathic effects of Panax notoginseng under different allelopathic chemicals resources and selection of appropriate rotation crops. The additive main effects and multiplicative interaction ( AMMI) model had been used to evaluate the stability of allelopathic effects of P. notoginseng on the varieties of corn, wheat and rice properly. The model could use not only to evaluate the stability of non-regional trial data but also explore the interaction between the rotation crop genotypes and donor substances more efficiently. Meanwhile, correspondence analysis can be used in the AMMI to evaluate genotype stability and donor substances. Ejingza No. 1 (g6) had stronger allelopathic effects with high stability, but Yunrui No. 1 (g9) which was appropriate rotation crop genotype, had weaker allelopathic effects with high stability. These findings will aid in choosing appropriate rotation crops and establishing proper rotation system.

SARS coronavims is an emerging virus. A lot of animals could be infected by SARS-CoV and Himalayan palm civets, as one of important hosts, is an ideal animal model. Viral genetic factors have been implicated in the emergence of SARS-CoV, with the suggestion that this virus is a recombinant between mammalian and avian coronaviruses. However, the recombination is unlikely to explain the appearance of SARS in humans.

This paper gives a brief introduction of the significance and background of the digital pictures' database in CQMU.It introduces its design methods,realization approaches,and solutions to the pictures' patent claim.Meanwhile this paper also han- dles its functions in editing pictures online,indexing pictures off line and its management.

Objective To analyze imaging of gastrointestinal stromal tumors(GIST),and to compare their imaging features with operational and pathological findings.Methods Clinical,imaging,and pathological data of 20 patients with GIST were collected.Results Imaging findings were endophytic or exophytic tumors with heterogeneous density or signal intensity,corresponding to hemorrhage,necrosis,and cystic changes.Imaging was correct for the location of the lesion in 11 of 16 primary GIST and 4 cases of relapsed tumors.Preoperational CT did not detect mesenteric,peritoneal,and omental metastasis in 5 cases. Hepatic metastases detected at CT (3 cases )were identified by operational findings.Conclusions GIST has some imaging features.CT is a useful tool in detecting and characterizating of lesions rather than detecting mesenteric,peritoneal,and omental metastasis.

It has been showed that there were obvious obstacle effects of Panax notoginseng replanting. Crop rotation was the main effective technique to overcome the obstacle. To find a reasonable crop rotation system for P. notoginseng, aqueous extracts from root, stem and leaf of P. notoginseng were analyzed for allelopathic effect on three maize varieties (which are often grown in regions where P. notoginseng grown). The main results were as follows: (1) Allelopathic effect of P. notoginseng stem and leaf extracts on the three other tested plants was stronger than that of root extracts; (2) Corn was more vulnerable to the effects of allelochemicals at seedling stage than at germination stage, and the corn root was more sensitive than aerial part to allelochemicals; (3) Lusan No. 3 and Yunrui No. 1 showed resistance to P. notoginseng allelopathy, with respective comprehensive sensitivity indexes (M3) of - 0.089 3 and -0.159 2, while Bainuo No. 1 is sensitive at M3 = -0.261 0. It then can be concluded that Lusan No. 3 and Yunrui No. 1 may be an alternative rotation plants for overcoming P. notoginseng continuous cropping obstacle.
