ABSTRACT
Objective To understand the distribution of allergens in children with common allergic diseases in Guangzhou, and to provide evidence for the prevention and treatment of environmental allergens in children with different allergic diseases. Methods This study enrolled a total of 6 869 children with allergic diseases, including wheezing diseases and asthma (1 013 cases), allergic rhinitis (660 cases), allergic conjunctivitis (422 cases), eczema (2 762 cases), atopic dermatitis (831 cases) and urticaria (1 181 cases). Western blotting was used to detect the serum allergen type E specific antibodies (sIgE) of the patients. The results were statistically analyzed. Results The total positive rate of sIgE in 6 869 children was 74.01%. The positive rate of male children (75.02%) was higher than that of female children (72.25%). The positive rate of inhalation allergens (53.47%) was higher than that of food allergens (57.39%). House dust mites and milk were the most common inhalation allergens and food allergens, respectively. Eczema was the most common allergic disease in infants and toddlers. Allergic rhinitis and urticaria were common in school-age children. Conclusion The main allergens causing allergic diseases in children in Guangzhou were dust mites and milk. Different allergic diseases had its specific allergens. It is necessary to take targeted prevention measures accordingly.
ABSTRACT
This paper summarized identification and reposition strategies of catheter malposition in 113 cancer patients with peripherally inserted central catheters(PICCs) during catheterization.In the process of PICC catheterization,catheter malposition was identified by ultrasound and ECG in a real-time manner.A series of timely and effective reposition procedures were performed by internal jugular vein blocking,breathing combined with anterior segment wire withdrawal Overall,111 cases were successfully repositioned,the success rate was 98.23％,and 2 cases failed because of other reasons such as diseases.
ABSTRACT
Expressions of interleukin-6 (IL-6) and its receptor (gp80、gp130) in 8 patients with Graves' disease (GD) were compared with those in 8 euthyroid patients with nodular goiter or benign thyroid adenoma. The thyroid tissues of GD expressed significantly higher IL-6 mRNA, gp130 mRNA and IL-6 protein than those of the control group, suggesting that activated IL-6/gp130 signal pathway in the thyroid tissue may contribute to the pathogenesis of GD.
ABSTRACT
OBJECTIVE:To review the relationship between endothelial progenitor cells and the re-endothelialization of vascular prosthesis in order to find out some effective ways to solve the most frequent complications of asotransplantation,thrombogenesis and intima hyperplasia.DATA SOURCES:A computer-based online search was conducted to identify articles related to endothelial progenitor cells and the re-endothelialization of vascular prosthesis published in Pubmed,Ovid and MD Consult database from January 2000 to December 2006 using the key words of "endothelial progenitor cells,vascular prosthesis,endothelialization".Meanwhile,CNKI database was searched for related papers published between January 2000and December 2006,the keywords were "endothelial progenitor cells,vascular prosthesis,endothelialization" in Chinese.STUDY SELECTION:The literatures included all the related papers about the roles of endothelial progenitor cells in the re-endothelialization of vascular prosthesis.Inclusive criteria:the study types were randomized controlled trials,drug stress test and clinical drug effect test; the samples were both human and animals.Exclusive criteria:Reviews and literatures without controls were excluded.DATA EXTRACTION:Totally 115 related literatures were collected,and 24 were accorded with the inclusive criteria.The excluded were 91 papers of reviews and repeated trials or drug effect studies.DATA SYNTHESIS:These related literatures,including not only animal experiments but also clinical detections,analyzed the relationship between endothelial progenitor cells and the re-endothelialization of vascular prosthesis and correlative promoting mechanisms.CONCLUSION:It is concluded that endothelial progenitor cells play an important role in the endothelialization after vascular prosthesis is grafted in vivo.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the efficacy of integrative Chinese and western medicine (ICWM) in treating diabetic foot.</p><p><b>METHODS</b>Sixty-three patients were randomly divided into the treated group (n = 33) and the control group (n = 30). Both groups were treated by same baseline treatment with vasodilator, anti-agglutination agents and external treatment, to the treated group, Chinese drugs were given additionally according to the Syndrome Differentiation.</p><p><b>RESULTS</b>In the treated group, the treatment showed markedly effective in 12 patients, effective in 18 and ineffective in 3, the total effective rate being 90.0%, while in the control group, the corresponding numbers were 9, 14, 7 and 76.7%, comparison between the two groups showed significant difference (chi 2 = 15.8, P < 0.05). The case number of Grade II, III and IV in the treated group reduced, and those recovered to Grade 0 increased, as compared with those in the control group, the difference was significant (P < 0.05). Patients with healing of ulcerative wound and fresh wound granulation in the treated group, as compared with those in the control group, the difference was significant (P < 0.05). Levels of fasting blood glucose and blood glucose 2 hrs after meal were all improved in both groups, which showed significant difference as compared with those before treatment (P < 0.05).</p><p><b>CONCLUSION</b>The efficacy of ICWM treatment in treating diabetic foot was better than the treatment of western medicine alone.</p>

OBJECTIVE To investigate the etiology, prevention and treatment of colon ischemia after operation for abdominal aortic aneurysm (AAA). METHOD Seven of 140 cases complicated with colon ischemia who had received AAA operation were analyzed retrospectively. RESULTS Three cases underwent emergency operation. The seven cases were subjected to removal of AAA, implantation of prosthesis, and ligation of the inferior mesenteric artery. Two cases had the ligation of the bilateral internal iliac artery (IIA). Epilateral IIA was ligated in 2 cases. Bowel resection was carried out in 3 cases, 1 of which received reconstruction of the inferior mesenteric artery (IMA). Three cases received conservative therapy, but died from multiply organ failure. CONCLUSION Correct prevention and management of colon ischemia can effectively reduce the operative morbidity of AAA patients.

ABSTRACT
Objective To study the etiology, diagnosis and treatment of acute occlusion of abdominal aorta(AOAA). Methods Clinical data of 35 patients with AOAA admitted to our hospital from January 1980 to August 2001 were analyzed retrospectively. Results There were 17 patients with acute aortic embolism(AAE) and 18 patients with acute aortic thrombosis(AAT) . All cases had total occlusion of abdominal aorta,and bilateral iliac arteries were involved. All the 35 cases underwent operations, including bilateral transfemoral thromboembolectomy by Fogarty balloon catheter in 18 cases, thromboembolectomy via laparotomy aortotomy in 11 cases, aortobiiliac reconstruction in 2 cases, aortobifemoral bypass in 2 ( 1 had profundaplasty) and axillobifemoral bypass in other 2 cases. Operative mortality was 25.7%(9/35). After the operations, artery embolism recurred in 3 cases; 3 patients required amputation; renal failure occurred in 3 cases and paraplegia in 4; ischemic colitis occurred in 5, impaired sexuality in 1 and incomplete intestinal obstruction in 1. Conclusions AOAA is an urgent disease with high mortality. Fast preoperative diagnosis and prompt operation are the keys to salvage the patient. Color Doppler is the first choice of diagnosis. Fogarty balloon catheter thromboembolectomy and vascular reconstruction are effective treatments for this disease.
ABSTRACT
AIM: To observe the effect the combination of hydrobromidum (654 2) and salviae miltiorrhizae on diabetic peripheral neuropathy (DPN). METHODS: sixty two cases of DPN were given the normal treatment of diabetes. Based on the treatment, they were divided into three groups at random. The first group (n=24) was given the combinction 654 2 and salviae miltiorrhizae, the second group (n=20) was given 654 2 alone, and the third group (n=18) was given salviae miltiorrhizae alone. RESULTS: The effertive rates in the first, the second and the third group were 79.2 %, 45% and 27.8 % (P
