In the USA, the certification of Assistive Technology Professional （ATP） has been used to supervise the development of AT service, while China is at the beginning of AT service. The current situation and the effects about the certification of ATP, how to get the ATP, the requirements someone must have were discussed in the paper.

Objective:To explore the clinical characteristics and diagnosis and treatment of occult poisoning caused by long-acting anticoagulant rodenticides.Method:Records of 12 patients from July 2008 to April 2011 diagnosed as anticoagulant rodenticide occult poisoning,who had been misdiagnosed initially at other hospitals were analyzed retrospectively.Elements from the records included clinical symptoms and signs,laboratory findings for prothrombin time (PT) and activated partial prothrombin time (APTT),and initial misdiagnosis and treatment outcome at our hospital.Results:The clinical presentations of patients were insidious and serious,often presented as skin ecchymose,hematuria,menorrhagia and gastrointestine bleeding.Laboratory examinations showed prolonged PT and APTT; bleeding was controlled effectively by administoring vitamin K1 daily.There were statistical difference between PT and APTT before and after the treatment (P＜0.01).Conclusion:Coagulation disorders might be caused by the reduced acquisition in vitamin K dependent coagulation factors,which tends to be neglected due to a hidden medical history,delayed signs of poisoning,and various organs involved.A detailed patient history and systematic review may improve the diagnostic accuracy.Once diagnosed is made,vitamin K1 should be given as soon as possible.

0.05). However, the 5-year local control rate appeared significantly different in three groups (?~2=7.239, P0.05). The 1-,3-,and 5-year disease-free survival rate among three groups were significantly different in the three groups (79.1%, 41.9% and 35.6% for CFR group, 85.7%, 57.1% and 38.1% for FHR group, and 95.4%, 62.8% and 58.1% for LAHR group) (?~2=6.60,P0.05). The incidence of loss of hearing, the radiation-induced temporomandibular joint lesion, and the radiation-induced brain injury was 31.3%, 41.9% and 9.3% in CFR group, and 25.0%, 35.7% and 7.1% in FRH group, and 22.7%, 35.7% and 7.0% in LAHR group, respectively. Conclusion A better 5-year local control rate and disease-free survival rate were achieved in patients in LAHR and FHR groups than those in CFR group. There are no differences in the incidence of late complications and overall survival rate among three groups.

Objective To decrease radiation induced toxicities especially mucostis in patients with locally advanced nasopharyngeal carcinoma( NPC ) who underwent concurrent radiochemotherapy, the maximum tolerated dose and dose limited toxicities of capecitabine combination with cisplatin were observed. Methods From Aug 2006 to Oct 2007, 24 patients with intensity modulated radiotherapy(IMRT) and concurrent chemotherapy with capecitabine and cisplatin for nasopharyngeal carcinoma(stages Ⅲ-Ⅳ) were enrolled in this study. There were four dose-level groups of Capecitabine[625-1250 mg/(m2 ·d) , d1-14]and fixed cisplatin dose[20 mg/(m ·d) ,d1-5) ]MRI and CT scan were used for evaluation of tumor shrinkage. Treatment related toxicities were evaluated according to the common toxicity criteria( NCI-CTC Version 3.0). Results The acute side-effects include Grade 3 or Grade 4 mucosal toxicity(lasting for at least 5 d) and Grade 3 or Grade 4 non-mucosal toxicity were evaluated. Group 625 mg/m2 and Group 825 mg/m2 had none, Group 1000 mg/m2 had 6 patients and Group 1250 mg/m2 had 3 patients for mucosal toxicity, which were the main dose-limited toxicity and relevant to the dose of capecitabine apparently( P < 0. 05 ). There was also a trend of increase by the dose level of capecitabine for other toxicities. The median follow-up time for all patients was 28. 5 months. The locoregional recurrence occurred in 2 patients and distant metastasis in 2 patients. Two-year overall survival rate and locoregional control rate were 100% and 91.7%, respectively.Complete response and partialresponse were found on MRI or CT scan in patients of 29. 2% at the end of treatment and 83. 3% after three months, respectively. Conclusions The combination regimen of capecitabine and cisplatin is safe and effective according to the preliminary result. Toxicities related to radiochemotherapy for NPC were significantly associated with the dose level of chemotherapy.

Objective To observe the clinical efficacy of ZHU Lian's acupuncture activating method with type 1 manipulations in treating hypotonic cerebral palsy.Method Sixty patients with hypotonic cerebral palsy, aged 9-59 months, were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by ZHU Lian's acupuncture activating method with type 1 manipulations, while the control group was intervened by acupoint injection of vitamin B1 and B12. The two groups were treated once a day, 5 sessions as a treatment course. The Gross Motor Function Measure-88 (GMFM-88) was evaluated before the treatment and after 10 treatment courses.Result The GMFM-88 score was significantly changed after the treatment in both groups (P<0.05). After the intervention, the GMFM-88 score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion ZHU Lian's acupuncture activating method is an effective approach in treating hypotonic cerebral palsy.

AIM: To examine the alteration of local renin-angiotensin system of dogs with myocardial ischemia and external counterpulsation treatment and its mechanism. METHODS: Acute myocardial ischemia was induced by occluding the LAD of ischemic and ECP groups. The tissue renin activity and angiotensin(AngⅡ) level in ischemic myocardium and aorta were measured. The expression of angiotensinogen and renin mRNA were detected by RT-PCR. RESULTS: Renin activity, AngⅡ level in ischemic myocardium and AngⅡ level in aorta of ECP group were lower than those of MI group. Except for renin in ischemic myocardium, angiotensinogen mRNA and renin in ischemic myocardium and angiotensinogen mRNA in aorta of ECP group were reduced to normal level. CONCLUSION: The inhibitory effect of ECP on cardiovascular renin activity and angiotensinogen gene expression could be one of the mechanisms by which ECP protects ischemic myocardium.

AIM: To examine the effect of external counterpulsation(ECP) on renin-angiotensin system(RAS) and hemodynamics in dogs with myocardial ischemia and their relationship. METHODS: Acute myocardial ischemia was induced by occluding the left anterior descending of the dogs. The local renin activity, angiotensin Ⅱ(AngⅡ) level, angiotension-converting enzyme(ACE) activity were tested by biochemical methods and hemodynamics was recorded by a 8-channel physiological recorder. RESULTS: Ischemia could actiivate renin,ACE and AngⅡ in cardiovasculature and ECP reduced them except for renin in ischemic myocardium. Ischemia also could activate RAS in lung and kidney, which play an important role on circulating RAS, and ECP reduced them. Furthermore, ECP could improve hemodynamics and there existed a close relationship between local AngⅡlevel and hemodynamics. CONCLUSION: ECP can reduce local RAS and improve hemodynamics in dogs with myocardial ischemia, which might be one of mechanisms underlying the protective effect of ECP on ischemic myocardium.
