?AlM: To observe the application effect of hyperbaric oxygen in the patients with optic atrophy and influence degree for the hemodynamic parameters.?METHODS: Fifty patients with optic atrophy in our hospital from January 2012 to January 2014 were objected, they were randomly divided into control group ( conventional optic atrophy treatment group ) and observation group ( conventional treatment and hyperbaric oxygen treatment group ) , each group was 25 cases. Statistical analysis of two group before and after treatment eyesight, vision acuity, visual field defect and ophthalmic artery, central retinal artery blood flow parameters were undergone.?RESULTS: The sight, visual field sensitivity and field vision defect of observation group were all better than those of control group at first, second and third course after the treatment, arteriae ophthalmica and arteriae centralis retinae EDV and PSV were all higher than those of control group, Pl and Rl were all lower than those of control group were all significant differences (P<0. 05).? CONCLUSlON: The application effect of hyperbaric oxygen in the patients with optic atrophy is better, and the influence of treatment method for the ocular hemodynamic parameters are more active.

By combining with concrete examples ,the paper Introduces the basic concepts and errors of the statistical analysis in scientific papers ,analyzes the errors and ambiguities of practical application ,and make some coping strategies for reference.

OBJECTIVE:To draw a comparison between 6% Hetastarch(H)and Succinylated Gelatin(G)in fluid expansion and their effects on blood coagulation activity.METHODS:A total of 60 surgery patients who needed volume expansion with colloid fluid were randomized to H group and G group.According to the design,the same dose of H and G were infused into the patients.Before and after infusion,the vital signs were monitored and the venous blood samples were taken for the determination of indexes of coagulation,fibrinolysis and electrolyte.RESULTS:There were no significant differences in the vital signs between two groups.After volume expansion,blood platelets counts in two groups were significantly decreased,much as in H group.And the APTT in H group had been significantly prolonged.In group G,only FIB decreased significantly.After volume expansion,free Ca2+ and total Ca2+ were decreased in both groups.Low level of K+ in group G was noted following diluti-on,and Cl-in group H increased significantly.CONCLUSION:Both group showed good volume expansion effects and stable fi-brinolytic function.Hyperchloremia should be alert in group H,and if necessary,Ca2+ should be promptly added in two groups.

Objective To explore the effects of antagonist of angiotensin II(Ang II) receptors on acute pancreatitis(AP) of rats. Methods The Sprague-Dawley rats were divided randomly into normal group, AP group, AP+lower dose of valsartan(5mg/kg) group , AP+higher dose of valsartan(8mg/kg) group, lower dose of valsartan group and higher dose of valsartan group, and each group containing 6 animals. AP animal models were induced by intraperitoneal injection of cerulein. Valsartan was given by intragastric administration. The histopathological changes of pancreas were observed and scored, and the pancreatic edema was evaluated. The levels of plasma amylase (AMY) and pancreatic myeloperoxidase (MPO) were measured. Results Compared with AP group, the pathologic lesions of pancreas and pancreatic edema decreased in the group AP+ valsartan, and the levels of plasma AMY and MPO also reduced. Conclusion Pretreatment with antagonist of angiotensin II receptors in rat acute pancreatitis can markedly reduce pancreatic injury and inflammation.

We should foster the students'service idea of human centered, make them to be skillful and have morals. Thus they could serve patients with enthusiasm, win the praise of patients by reasonable charge and smallest wound.

Lead is a kind of poisonous heavy metal which is widely existed in our environment. It is so harmful for children’s health. The whole society has paid much attention to this problem all the time. Blood lead level is an important index which can measure how seriously children have been exposed to lead. By consulting the papers on the studies of children's blood lead levels,the sources and influencing factors of blood lead levels of children in China were reviewed in the present paper,meanwhile,some suggestions were provided to decrease the lead contact probability and improve children's health.

Systemic Sclerosis(SSc) is a fibrotic disease characterized by immunological abnormalities,vascular injury and increased accumulation of extracellular matrix.The etiology has not been fully elucidated yet,so we need to establish a suitable animal model for research.This review is to introduce murine model of bleomycin-induced SSc,and summarize research works on the pathogenesis and treatment of SSc based on this model.

The application of improved BP neural network together with the wavelet transform to the classification of surface EMG signal is described. The data reduction and preprocessing of the signal are performed by wavelet transform. The network can identify such four kinds of forearm movements with a high accuracy as hand extension, clench fist, forearm pronation and forearm supination. This paper compares the results by standard BP algorithm with that of Bayesian regularization together with LM algorithm. Experimental result shows that the improved BP neural network has a great potential when applied to electromechanical prosthesis control because of its enhanced training speed and identification accuracy.

Compareing domestic and foreign medical humanistic quality education,this paper analyzed the reason for the lack of medical humanistic quality and put forward countermeasures aiming at the reform of medical humanistic quality education in medical colleges and universities through learning from the practice and experience of foreign medical humanistic quality education.There countermeasure include:reforming the concept of medical humanistic Character education,innovateing the model of medical humanistic quality education,increaseing the construction of humanities quality curriculum system,training the professional skill of medical humanistic quality,establishing the evaluation-oriented effect system,exploreing the new model of modern medical professional education and medical humanistic quality education actively,and reconstructing the systematic system of medical humanisticing quality education.

Objective To explore the clinical analysis of Compound Erlongzuoci pill combined with auricular point stickingand vitamin B12 acupoint injection therapy on nervous tinnitus of middle and old aged.Methods 80 cases of middle and old aged patients with neurogenic tinnitus treated in our hospital from November 2015 to November 2016 were selected and randomly divided into the control group and the observation group, 40 cases of patients in each group, the control group was given Auricular Pressure Combined with vitamin B12 acupoint injection, the observation group was treated with Compound Erlongzuoci pills combined with auricular point sticking therapy and vitamin B12 acupoint injection,The clinical therapeutic effect of two groups, the tinnitus severity score of patients before and after treatment, the changes of tinnitus loudness and different frequency thresholds were compared between the two groups.Results The total effective rate of the clinical observation group was significantly higher than that of the control group, the difference between the two groups was statistically significant(P<0.05).Before treatment, there is no significant difference between tinnitus severity score, tinnitus loudness and hearing threshold between the two groups,the indexes after treatment in two groups were significantly improved(P<0.05), and the observation group tinnitus severity score, tinnitus loudness and different frequency thresholds were significantly lower than the control group, the difference was statistically significant(P<0.05).Conclusion Compound Erlongzuoci pill combined with auricular senile nervous tinnitus pressure and vitamin B12 acupoint injection therapy can significantly improve the degree of tinnitus patients, the clinical effect is confirmed.
