Objective: To prepare an X-ray developable alginate-barium sulfate microspheres as material for embolic agent. Methods: The emulsification-internal gelation technique was used to prepare alginate microspheres and the orthogonal design was adopted to optimize the technique. The diameter, shape, dispersibility, stability, suspension property, coating ratio and developability under X-ray of the microspheres were examined. Results: The average diameter of the microspheres was (53. 08± 32. 72) μm; they were well distributed and had a round shape. The ratio of the destroyed microspheres was (2. 0±1, 1) % after heated at 100°C for 2 h,(86. 0± 19. 2)% after frozen at - 4°C for 24 h, (39. 0± 14. 7)% after vibrated at 37°C for 24 h, and (10. 3±3. 2)% after irradiated with 60Co(10kGy) for 0. 5 h. The ratio of sedimentation volume in 0. 25 % suspension of sodium alginate microspheres was (0. 92±0. 018). The coating rate was (69. 2±13.2) % when the feeding amount of barium sulfate was 2. 0 g, and the result of X-ray development was good. Conclusion: Alginate-chitosan can be used for the preparation of barium sulfate microspheres; and the emulsification-internal gelation technique can prepare the microspheres with good dispersibility and shape.

Objective To explore the pathogeny, pathology, ultrasonic and clinical expression of upper extremity deep venous flow obstruction and superior vena cava syndrome. Methods Retrospective analysis and summarize the disease changes of 10 cases in recent 5 years. Results 7 patients of 10 cases were superior vena cava syndrome, in which 4 cases caused by upper right lung malignant tumor, 3 cases caused by upper and media mediastinal malignant tumor. 2 patients of 10 cases were found thrombosis in right subclavian vein caused by duct of artificial pacemaker. The left 1 patient was no reason thrombosis in right axillary vein. Conclusion Ultrasonography combine with color and spectral Dopper image can evaluate the clinical development and therapeutic efficiency, which is a useful and effective non-invasive examination.

Objective To analyze the etiology of diabetes ketoacidosis(DKA) in children with type 1 diabetes.Methods Totally 850 person-time of type 1 diabetes children in recent 20 years in our hospital were selected as studied subjects. Two hundred and twenty-five person-time of them were hospitalized because of DKA.Fifty-six cases (131 person-time) were due to recurrent DKA.These patients were classified into 2 groups according to onset time: group 1(diagnosed from 1982 to 1991) and group 2(diagnosed from 1992 to 2001).Results The analysis of recurrent DKA suggested that 71.8 % of them was due to infection, 20.4 % of them did not obey diabetic diet and 9.2 % of them discontinued insulin injection. The etiology of DKA showed no difference in two groups. The number of recurrent DKA in two groups was significantly different (P

Objective To evaluate the associations of human leukocyte antigen(HLA)-DQ gene with autoimmune polyglandular syndrome(APS),type 1 diabetic mellitus(T1DM) and autoimmune thyroid disease(AITD).Methods Fifteen cases of APS,29 cases of T1DM and 40 cases of AITD were selected as research subjects,while 27 healthy children were selected as controls.The DQA1 and DQB1 alleles were determined by polymerase chain reaction(PCR) and sequence-based typing method.The difference of their frequency in children and adolescents was analyzed.Results Compared with controls,APS and T1DM patients had increased frequency of subjects with DQA1*0301,0501(all P

Objective To investigate the effect of enteral nutrition tolerance assessment form on the early enteral nutrition tolerance in patients with gastric cancer after operation. Methods According to the admission sequence, 108 patients with gastric cancer were divided into the control group and the experiment group with 54 cases in each group. Enteral nutrition was used in the control group, while enteral nutrition tolerance assessment form was used to evaulate and care patients in experiment group. Finally, the two groups were compared in the anal exhaust time and the rate of complications. Result Anal exhaust in the experiment group was significantly earlier than that in the control group and the rate of complications was significantly smaller than that of the control group (P < 0.05). Conclusions The enteral nutrition tolerance assessment form for systemic evaluation and intervention is effective in improvement of the patients′tolerance to enteral nutrition in early postoperative enteral nutrition support to patients with gastric cancer. It can promote the recovery of patients.
