Some human leucocyte antigens(HLA),espeually class Ⅱ genotypes such as HLA DQ/DR are closely linked to type 1A diabetes mellitus(T1ADM).But the genetic susceptibility of HLA DR/DQ are different between Caucasian and Asian populations.The aspartic acid at position 57 of DQ? can not confer resistance to T1ADM in Asians.DQ2 and DQ8 are the well-known susceptible genotypes in Caucasians while DQ4 and DQ9 are in Asians.An unexpected high risk of T1ADM is observed for the linkage disequilibrium between DRB1*0301/ DRB1*0401 and DQ2/DQ8 in both the populations.The DQB1*0302,DQA1*0501,DRB1*0401,*0402,*0407 are associated with T1ADM in Caucasians,but it is not the case in Asians.In contrast,DQB1*0401 shows a positive association to T1ADM in Asians,has a protective effect against T1ADM in Caucasians.Additionally DRB1*09 could be another susceptible gene in Asians.

Objective To evaluate the effect of excise training on the pulmonary function in patients with chronic obstructive pulmonary disease(COPD).Methods Totally 55 COPD patients received excise training,the patients’pulmonary function,6-minute walking test(6MWT)and St.George's respiratory questionnaire(SGRQ)were measured before and after the 6 months intervention. Result The pulmonary function,6MWT(exercise tolerance)and the quality of life were significantly improved(all P<0?01). Conclusions Excise training can improve COPD patients’exercise tolerance,relieve the symptoms of dyspnea,and thereby improve patients’quality of life?

Assistive Technology Act of the USA is a very important law for the persons with disability in USA. The background of the Assistive Technology Act of the USA was reviewed and the guarantee of laws for the disabilities was discussed in the paper. From which, some theory and practice for special education of China can be obtained, and some experience and enlightenment for setting up related laws in China also can be worked out.

Objective:To investigate the eating disorder and mood among students of a female university in Beijing.Methods:352 female students from a same-sex college in Beijing,between the age of 17-25 years were in- vestigated by Eating Disorder Inventory(EDI)and Profile of Mood States-Short Form(POMS-SF).Their weight and height were also collected for calculating for their body mass index(BMI).Results:Female university students showed serious tendency of eating disorder.The negative attitudes to body and body satisfaction were serious among normal BMI female university students.The behaviors and attitudes to eating disorders among the students of fresh-woman and senior were significantly higher than other grades(x~2=17.94,P

Objective To study the effect of simvastatin(SV) on NF-kappa B p65 expression in liver of insulin resistant rats. Methods Male Wistar rats were divided into two groups:basic chow(NC,n=15)or high-fat diet(HF,n=20)for 10 weeks feeding, then assessed by euglycemic-hyperinsulinemia clamp technique. Rats in HF group were treated with(HFS,n=5)and without (HFN,n=5) SV 10mgkg-1d-1 in gavage for 5 weeks.NF-kappa B p65 expressions were tested with Western blot. Results The glucose infusion rate (GIR) in HF group decreased significantly compared with NC group (P

Objective To explore the effect of eletroacupuncture (EA) on angiogenesis after cerebral ischemia and reperfusion through observing the number of peripheral blood endothelial progenitor cells (EPCs) and the expression of vascular endothelial growth factor (VEGF) in the hippocampus.Methods Among 50 male Sprague-Dawley (SD) rats,10 were randomly selected as a control group (CG).Qi deficiency and blood stasis were induced in the other 40 rats by intragastric administration of dahuang daily for 7 days.A model of focal cerebral ischemia and reperfusion injury was then created by thread-occlusion of the middle cerebral artery,except in 10 rats selected for the sham operation group (SOG) who received the same operation without tightening the thread.The successfully modeled rats were divided into a model group (MG,n =10) and an electroacupuncture group (EAG,n =10).The rats in EAG started acupuncture treatment the next day after modeling,while no treatment was given to those in the other groups.On day 1,3 and 7 after the modeling,the neurological functioning of the 4 groups was assessed using Basso-Beattie-Bresnahan locomotion scoring and the number of EPCs in the peripheral circulation was detected by flow cytometry.On the 8th day,all the rats were decapitated and the VEGF expression was detected immunohistochemically.Results The average BBB locomotion score of the EAG rose significantly from (4.50 ± 1.05) on day 1,to (13.67 ± 1.21) on day 3,and then further to (20.00 ±0.89) by day 7,significantly higher than that of MG at the same time points,but still significantly lower than that of the control group.The average number of EPCs in the peripheral circulation in the MG also increased from (26.83 ± 6.05) on day 1 to (33.67 ± 5.39) on day 3,and decreased to (32.83 ± 5.04) on day 7 after modeling,significantly lower than that of the CG [(45.50 ±9.40),(42.17 ±4.62) and (41.33 ±5.50)],the SOG [(58.00 ±8.05),(59.67±4.84) and (53.83 ±5.38)[and the EAG [(66.17 ±4.36),(127.50 ±73.75) and (55.00 ±35.15)] at each time point.After occlusion,the average expression of VEGF-positive cells in the hippocampus of the EAG [(27.80 ± 2.39)％] was significantly higher than that of the MG,and both were significantly higher than that of the CG.Conclusions Eletroacupuncture can up-regulate VEGF expression and EPCs in the peripheral blood in rats after cerebral ischemia-reperfusion,which can promote angiogenesis and neural functional recovery.

AlM: To explore the clinical application effect of phacofragmentation combined with vitrectomy in the treatment of traumatic lens dislocation.
METHODS:Totally 16 cases (16 eyes) of traumatic lens dislocation treated with phacofragmentation combined with vitrectomy were retrospectively analyzed, including 6 cases of high intraocular pressure ( lOP) and 10 cases of vitreous hemorrhage, and 1 case of retinal detachment. All patients were given conventional flat line standard three channel vitreous operation incision to remove the anterior, middle part and peripheral vitreous around lens dislocation. The crystalline lens were drawn to the center cavity of vitreous body and treated by ultrasonic disintegrator. ln the operation, the retina was examined and 8 of them had no retinal damage and in the first stage underwent fixation of posterior chamber intraocular lenses.
RESULTS: All crystalline lens dislocated were completely grinded and suctioned. There was no retinal detachment occurred in 3mo followed up. 16 eyes had normal lOP (12-20mmHg) at 1wk after operation. The average visual acuity was improved and with 8 cases got improved of 0. 2 or more 1wk after operation.
CONCLUSlON: Our research shows that phacofragmentation combined with vitrectomy is a safe and effective method for the treatment of traumatic lens dislocation. The patients with nondestructive retina in the operation are feasible to do first stage operation of intraocular lens suture fixation, which contributes to the best visual acuity.
