In this article, we applied single multiple factor analysis and paired iron supplement test to determine the effect of IDA on mental development in 6-36 months infants and children.333 infants and children aged from 6 to 36 months in kindergarten were selected for the experiment. The social environment, physical condition, developmental quotient (DQ), and so on were investigated. The results showed that the DQ in IDA infants (95.32, 9.47) was lower than that of the normal (101.62,10.28) P

To introduce the necessity,contents and means of vocational training among fresh nurses (who work in the first year after graduation),to explore how to enhance the comprehensive professional qualitiy training mode for graduated nurses.

Objective To investigate the predictive value of peripheral leukocyte and its subtypes count on cerebral-cardiovascular events in patients with unstable angina pectoris.Methods From December 2000 to January 2003,141 patients(aged 41-84 years) with unstable angina pectoris referred for coronary angiography were enrolled and their peripheral leukocyte and its subtypes were counted.The major adverse cerebral-cardiovascular events rate of these patients during 46.2?6.6 months of follow-up were assessed.Results A total of 55 cerebral-cardiovascular nonfatal events and 8 deaths were observed.After adjusting the risk factors of diabetes mellitus,smoking,hypertension,hyperlipidemia,prior myocardial infarction,family history,and blood fibrinogen and uric acid level,leukocyte count was positively associated with cerebral-cardiovascular events(adjusted relative risk 1.31,95% CI 1.15 to 1.49).The monocyte count in patients with cerebral-cardiovascular events was higher than that in patients without cardiovascular events(P

Objective To assess the application of spiral CT angiography in the diagnosis of Takayasu arteritis.Methods Vascular imaging features of three-dimensional CT angiography of 56 patients with Takayasu arteritis were analyzed retrospectively.Results The vascular imaging of all the patients were qualified for diagnosis.A total of 175 arteries were involved,including subclavian arteries (36.00%,63/175) with a high percentage of the left subclavian arteries (24.00%,42/175) ,common carotid arteries (29.71%,52/175) and renal arteries (10.86%,19/175) .The affected artery wall had varying degrees of concentric or eccentric thickening,and stenosis or occlusion of lumen was observed.Conclusion Threedimensional spiral CT angiography can make clear diagnosis of Takayasu arteritis,including the scope,extent and nature,and thus is worthy of clinical application.

Objective To evaluate the effect of different education models on the self care ability of peripherally inserted central catheters (PICC) placement patients.Methods The randomized controlled trial (RCT),controlled clinical trail (CCT),self-controlled trial and cohort study on self care ability of patients with PICC placement were collected using databases by manual and Internet searching.Data were analyzed with Revman5.0 software,data which could not be gathered were expressed by descriptive analysis.Results Eight articles were included in the study.The results of Meta-analysis revealed that different education models could significantly improve the self care ability of PICC patients in the intervention (experimental) group.Conclusions Different education models had significant meaning on the self care ability of PICC placement patients.

0.05, but there was a larger deviation with Model 930.

Objective To evaluate the role of different kinds of body positon in the stomach CT scanning.Methods It included 30 normal adults who underwent CT scanning in four differnent kinds of body positions.The relationship between the body position and the image appearence in the each part of stomach has been analysed.Results The results showed that the adjusting of body position was useul in revealing gastric wall and perigastric organs.The best imaging result of fundus ventriculi part of stomach can be obtained with the head down and the feet high position while patients lie on his back.The best body position to reveal corpus ventriculi part is in prone position and the best body position to reveal pars pylorica part is in right lateral position.There is a very significant difference between supine position and the best revealing position of each part of stomach prespectively(?

Objective:To evaluate the role of using the double body position CT(DBP-CT)in the staging of advanced gastric cancer.Methods:We performed CT examination in 85 patients with advanced gastric cancer which were divided into the double postion group(55 cases)and the single position group(30 cases),after oral intake water agent.The preoperative CT findings of each group was compared with surgical findings respectively and the accuracy in the CT staging of advanced gastric cancer of each group was estimated.Results:The accuracy in the preoperative CT staging of double position group was 89.09%,and in single postition group was 60%.There was a significant difference(P＜0.05).Conclusion:Our findings show that the DBP-CT is surperior to the single position group in finding lesion,confineing the range of the tumour,and determing the degree of adjacent invasion.It can improve the diagnostic accuracy in the preoperative staging of advanced gastric cancers significantly.

Objective To investigate the role of hypoxia induced factor-1 α (HIF-1 α) signaling pathway in development of nonacoholic fatty liver disease (NAFLD) by using a rat model.Methods Forty SD rats were randomly divided into 5 groups (normal control group,4 weeks model group,8 weeks model group,12 weeks model group,and 16 weeks model group according to random number table).NAFLD model was induced by high fat diet.Serum biochemical parameters and liver histological examinations were observed.The HIF-1α,peroxisome proliferator-activated receptor α (PPARα),and nuclear factor-κB (NF-κB) mRNA transcriptions of liver tissue were detected with realtime PCR.Results Compared with the control group,a remarkable rise of serum alanine amiotransferase,triglyceride,cholesterol,and reduction of high density lipoprotein-cholesterol were observed in rats treated with high fat diet after 12 weeks and 16 weeks (P＜0.05).Compared with model group,steatosis,grade of inflammation,and degree of fibrosis in the liver were also significantly aggravated.Fed with high fat diet for 8 weeks,the expression of HIF-1α was significantly higher than that in the control group;the expression of PPARα in 4 weeks group was significantly higher than that in the control group.The expression of PPARα was again significantly elevated in 16 weeks group (P＜0.05);NF-κB expression was increased gradually with high fat diet (P＜0.05).The expression of HIF-1 α mRNA was related with PPARα (r =0.82,P＜0.05) and NF-κB (r =0.67,P＜0.05),and PPARα mRNA was related with NF-κB (r =0.78,P＜0.05).Conclusion HIF-1 α signaling may regulate PPARα/NF-κB and seems to be related with development of NAFLD.

Huoxue Tongmai Lishui method, a traditional Chinese medicine treatment for eliminating water, activating and promoting blood circulation, could inhibit fundus hemorrhage on experimental retinal vein occlusion (RVO) with high obvious effective rate, and improve symptoms in traditional Chinese medicine. The action mechanism may be related to reducing plasma viscosity and non-perfusion area, and the formation of collateral circulation.
