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.

ObjectiveTo investigate the effects of different therapeutic methods on borderline hypertension with metabolic syndrome patients. MethodsNinety borderline hypertension with metabolic syndrome patients were divided into three groups by random digits table with 30 cases: control group,conventional therapy group and intensive therapy group. The control group was given regular observation, the conventional therapy group took drug according to the disease situation; and the intensive therapy group not only formulated the aim of therapy, but also received diet control, sport therapy, healthy education and drug therapy. After 1 year's follow-up, the patients' changes were compared. ResultsAfter 1 year's follow-up,the levels of FPG, 2 h PG, 24 h mAlb and IMT were significantly increased(P ＜ 0.05 ), and the levels of other index had no significant changes (P＞ 0.05) in control group. The levels of FPG,2 h PG,TC and TG were significantly decreased and IMT was significantly increased(P ＜0.05), the levels of other index had no significant changes(P ＞ 0.05 ) in conventional therapy group. The levels of SBP, DBP, PP, FPG, 2 h PG, TC,TG,hs-CRP,24 h mAlb and HOMA-IR were significantly decreased and HDL-C, ABI were significantly increased (P ＜ 0.01 or ＜ 0.05 ) in intensive therapy group. After treatment, the levels of ABI and H DL-C were significantly higher and SBP, DBP, PP,TG, hs-CRP, 24 h mAlb, HOMA-IR, IMT were significantly lower in intensive therapy group than those in conventional therapy group (P ＜ 0.01 or ＜ 0.05 ). ConclusionsDrug therapy is efficient in borderline hypertension with metabolic syndrome patients, and intensive therapy can obviously improve the insulin resistance, to control the developing of hypertension can delay the vascular

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.
