Obiective To realize real-time data processing in lung ventilation reconstruction based on electrical impedance tomography(EIT). Methods The image reconstruction algorithms, plotting functions and matrix calculations are dynamic transferred with Matlab C++, Mathtools and VC++ to meet the requirements of data processing and imaging in real time.Results Image reconstruction and real-time data processing were realized successfully in lung ventilation based on EIT. Conclusion It provides a new strategy for real-time data processing of image reconstruction by EIT.

This study examined the difference in dietary intake between middle−aged and elderly Japanese and Chinese. Volunteers aged 50∼79 living in two cities in both Japan and China were recruited in local community service centers and were asked to complete a 3−day diet recording. The final results were based on 356 subjects (166 Chinese and 190 Japanese). In men, the Japanese subjects significantly consumed more energy, with a large proportion of the energy coming from carbohydrates, dietary fiber, vitamin A, vitamin B2, vitamin C and they consumed less iron, and a lower proportion of energy from protein and fat than in the Chinese subjects. In women, the Japanese subjects had significantly higher intakes of energy, the proportion of energy from carbohydrates, dietary fiber, calcium, vitamin A, vitamin B1, vitamin B2, vitamin C and they consumed less iron, with the proportion of energy from protein and from fat in comparison with the Chinese women. Fat intake provided more than 29% of the total dietary energy in Chinese subjects. Daily intake of food items was significantly greater in the Japanese participants, both men and women (18.54±2.85, 20.11±2.40, respectively), than in the Chinese subjects (14.11±3.62, 15.51±4.15, respectively) (p<0.01 by Mann Whitney U−test). The present study suggests that the middle−aged and elderly Chinese subjects should increase their variety of foods consumed while decreasing their consumption of high−fat foods. For the Japanese subjects, the higher intake of total calories among the woman should also be noted.

In the field of gene delivery, nonviral vectors are getting more attention due to the advantages which do not belong to viral vectors. But kinds of polypeptides are important to construct ideal nonviral vectors. The paper reviews the development in the research of polypeptides as components of nonviral vectors like as the backbone, the targeting moiety, the endosome membrane destabilizing agents and the nuclear localizing signals.

Based on the medical immunology exquisite course of Dalian city,we expound the guiding thought,construction and system evaluation of medical immunology test bank,in order to normalize examination,consummate teaching quality control system and improve teaching quality.

Objective To summarize the clinical expedence in surgical treatment and prognosis of artrial septal defect(ASD)in adults and to know well the surgical indication of ASD in adults.Methods 32 patients over 20 years old with the left to right shunt and preoperative mean pulmonary artery pressure less than 8kPa underwent direct surgical repair for ASD under extra corporeal circulation.Results All patients survived after surgery,there was no surgical mortality in our group.32 patients were followed-up,29 of them with disappearing symptoms and 3 of them still had various symptoms.Conclusion The following condition ASD in adults who have slight to moderate clinical symptoms should be operated:cardiac enlargement eardiothoracic ratio over 50% and pneumonemia in X-ray films;right ventricular hypertrophy with a right axis deviation of incomplete right bundle branch block on the electrocardiogram;diameter of ASD over 1.5cm in ultrasonic cardiogram.

Objective To observe the distribution and imaging of radiolabelled arginine-glycineaspartic(RGD)peptide(99Tcm-3P4-RGD2)in collagen-induced arthritis(CIA),and to investigate the possibility of new markers for monitoring the angiogenesis of rheumatoid arthritis(RA)before and after treatment by single photon emission computed tomography(SPECT)labelled with 99Tcm-3P4-RGD2.Methods Type Ⅱ chicken collagen was injected into the tails of Wistar rats to establish arthritis models.The CIA-Wistar rats were randomly divided into three group:the Avastin group,the recombinant human tumor necrosis factor-α receptor Ⅱ group,and the blank control group.The changes of the arthritis index,joint pad thickness and radiological of T/NT before and after treatment were observed.The level of vascular endothelial growth factor(VEGF)in the serum was measured by enzyme-linked immuno sorbent assay(ELISA).The back metapedes pathological section was analyzed by Hematoxylin and Eosin stain(HE)and Safranin O stain as well as arthritic pathology index was also scored.The synovial expression level of VEGF was measured by immuno-histochemistry.The stain level of VEGF was assayed by semiquantitative approach.T test was applied for the comparison of two intergroup samples.Results Abnormal radioactive concentration appeared in the arthritis of the CIA-Wistar rats(1.40±0.17,1.32±0.20,1.30±0.08,P＜0.05).Through the treatment of Avastin and recombinant human tumor necrosis factor-α receptor Ⅱ,the radiological of T/NT decreased significantly(0.43±0.14,0.40±0.12,t=17.710,16.812,P＜0.05).After the treatment with Avastin and recombinant human tumor necrosis factor-α receptor Ⅱ,the severity of synovial pannus,joint pad thickness,arthritis index and the expression of VEGF were all decreased.The radiological of T/NT was positively correlated with the indices mentioned above(r=0.753,0.800,0.892,all P＜0.01 respectively with the the rhTNFR:Fc group)(r=0.701,P=0.001;r=0.502,P=0.024;r=0.481,P=0.032 individually with the rhTNFR:Fc group).Conclusion When 99Tcm-3P4-RGD2 is injected through the tail vein of Wistar rats,it can show the pathological changes of arthritis clearly.99Tcm-3P4-RGD2may be the new eikonogen to monitor the angiogenesis of RA before and after treatment.

AIM: To evaluate the clinical effects of compound trabeculectomy for primary angle-closure glaucoma with persistent high intraocular pressure.
●METHODS:Thirty-three cases ( 34 eyes ) with primary angle - closure glaucoma were executed compound trabeculectomy. All patients were divided into two groups: group A: 18 cases ( 18 eyes ) were executed compound trabeculectomy under high intraocular pressure higher than 35mmHg after using lOP-lowering medicine for 48-72h; group B: 15 cases (16 eyes) were executed compound trabeculectomy, the intraocular pressure was normal after using lOP-lowering medicine.
●RESULTS:Thirty-four eyes were successfully completed surgery with follow-up of 6 to 18mo and there were no serious complications, including suprachoroidal hemorrhage. The visual acuity before operation in group A and group B were 0. 02 ± 0. 01, 0. 04 ± 0. 02, respectively. And the postoperative visual acuity in group A and group B increased 0.2±0. 06, 0. 3±0. 07, respectively (P<0. 01). All of them, intraocular pressure with 30 eyes were controlled in 9-23 mmHg, 3 eye was controlled by normal through adding in several kinds different lOP-lowering medicine. One eye was failure. Compared to preoperation, postoperative intraocular pressure of two groups were decreased by normal, which were 17. 9 ± 9. 1 mmHg and 15. 4±8. 4mmHg, respectively (P<0. 01). There was no significant difference between two groups for postoperative intraocular pressure.
●CONCLUSION: The primary angle-closure glaucoma with persistent high intraocular pressure should be executed compound trabeculectomy decisively, even under high intraocular pressure, which prevent further damage and loss of visual function. As long as to fully consideration the preoperation, intraoperative careful operation, careful nursing, it is safety and effective to have compound trabeculectomy under the continuous high intraocular pressure for primary angle-closure glaucoma.
