Objective:To investigate esomeprazole combined with early enteral nutrition on the immune function and intestinal flo-ra in the elderly by patients with severe acute pancreatitis. Methods:Totally 78 elderly by patients with severe acute pancreatitis were selected and randomly divided into the observation group (39 cases) and the control group (39 cases). The control group was treated with early enteral nutrition therapy, and the observation group was treated with esomeprazole additionally. The treatment course was 14 days. Results:The total effective rate of the observation group was higher that of the control group (P<0. 05). The abdominal pain relief time, recovery time of bowel sounds, abdominal distension relief time, and the time of serum amylase returning to normal and u-rine amylase returning to normal in the observation group were all better than those in the control group (P<0. 05). The incidence of intestinal flora disorders in the observation group was lower than that in the control group (P<0. 05). After the treatment, CD3+, CD4+ and CD4+/CD8+ increased in both groups (P<0. 05), and those in the observation group were higher than those in the con-trol group (P<0. 05). Serum amylase and urine amylase decreased in both groups after the treatment (P<0. 05), and the decrease in the observation group was more significant than that in the control group (P<0. 05). No serious adverse drug reactions appeared in both groups. Conclusion:Esomeprazole combined with early enteral nutrition in the elderly by patients with severe acute pancreatitis shows significant effect, and the effect may be related with improving the immune function and intestinal flora.

Objective To investigate the efficacy and safety of percutaneous Cool-tip Radiofrequency ablation guided by computerized tomography (CT) for the treatment of advanced lung cancer. Methods 32 patients of advanced lung cancer with 102 different pathological types were treated with MERP technique. The patients' blood pressure,pulse rate and oxygen saturation were monitored during the procedure. The hepatic, pulmonary and renal functions were examined before and after the procedure. The tumor bulk was compared with CT before and after the treatment. Results There were no any changes in the blood pressure, pulse rate and oxygen saturation in the whole series before, immediately after the term ination and one month after the procedure, nor did the hepatic,pulmonary and renal function as well. The bulk of the tumor in this group as a whole enlarged by the end of the first month after the therapy. The CT scanning of the tumor at the end of the third month revealed that there had 23 CR, 53 PRa, 24 PRb, and 2 NR among 102 tumors. Conclusion The Cool-tip Radiofrequency ablation is a promising mini-invasive technique for the treatment of advanced lung cancer with the satisfactory efficacy and safety.

BACKGROUND:Microporous vacuum polysaccharide hemostatic microspheres are derived from degenerated potato plant starch and prepared through special processing. It is an ideal absorbable polymer styptic material with independent intelectual property rights. OBJECTIVE: To observe the degradation of microporous vacuum polysaccharide hemostatic microspheres and detect the safety indicators of body fluids by implanting microporous vacuum polysaccharide hemostatic microspheres in rats. METHODS:0.1-0.2 g microporous vacuum polysaccharide hemostatic microspheres were implanted subcutaneously on the left side of the spine in 12 rats. At the 1st, 3rd, 7th and 14th days after implantation,the degradation of microporous vacuum polysaccharide hemostatic microspheres in the tissue was observed. Another 15 rats were selected, of which 5 rats were taken as the control group and fed normally, and 10 rats were subjected to anesthesia. Two incisions were made on both sides of the spine, about 5 cm, deep into the muscular layer of 0.3 cm. The right amount of hemostatic microspheres were sprayed on the incisions and covered the entire wound, then the incisions were sutured. The 10 rats were raised normally for 14 days. The various indicators of body fluids such as appearance features, activities, excretion, feeding were detected. Finally, the rats were dissected, and the gross morphology and color changes of main organs were observed. RESULTS AND CONCLUSIONS: The microporous vacuum polysaccharide hemostatic microspheres buried in rats were completely degraded and absorbed within 7 days. After spraying the right amount of microporous vacuum polysaccharide hemostatic microspheres on the incision, the vital signs and biochemical indicators, such as blood and urine tests were all normal. The gross morphology and color of main organs such as liver, spleen, brain and kidney were not found significant anomalies. These results demonstrate that microporous vacuum polysaccharide hemostatic microspheres can be degraded into monosaccharide by amylase and can be completely degraded and absorbed within 7 days, without any side effects to tissues and organs.

BACKGROUND:A cross-emulsification patented product of microporous polysaccharide hemostatic powder was prepared using potatoes as raw material with independent intel ectual property rights.
OBJECTIVE:To observe hemostasis effects of microporous polysaccharide hemostatic powder on soft tissue trauma.
METHODS:A wound, about 3 cm long and 0.5 cm deep, was made on the abdominal soft tissue of rabbits in the experimental group 1, and then microporous polysaccharide hemostatic powder, 1.0-2.0 g, was sprayed directly on the wound. In the experimental group 2, a wound, about 3.0 cm long and 1.0 cm deep, was made on the abdominal soft tissue of rabbits, and then microporous polysaccharide hemostatic powder, 1.0-2.0 g, was sprayed directly on the wound. Another rabbits with untreated wound served as controls.
RESULTS AND CONCLUSION:Microporous polysaccharide hemostatic powder formed a“pasty gel”covering the bleeding wound that achieved hemostatic effect. The bleeding time was (15.25±1.04) seconds in the experimental group 1 and (11.25±1.89) seconds in the experimental group 2. The marked effective and effective rates for hemostasis were 87.5%and 100%, respectively. In the control group, the bleeding time was more than 5 minutes. Hematoxylin-eosin staining showed mild muscle edema, vasodilatation of smal blood vessels, and few scattered endoplasmic neutrophils infiltrated at 24 hours after treatment with microporous polysaccharide hemostatic powder;til the 7th day, inflammation subsided, mild fibrosis was visible on muscle tissue surface, the hemostatic powder was completely absorbed, the wound tissue was close to the normal tissue, and there were no significant changes in muscle cells. These findings suggest that microporous polysaccharide hemostatic powder can be used for hemostasis of soft tissue trauma.

Abstract A novel luminol electrochemiluminescence strategy based on titanium dioxide/carbon nanotubes ( TiO2/CNTs) nanocomposites for detection of glucose was developed. First, the TiO2/CNTs nanocomposites were prepared by a sol-gel method and modified on the glassy carbon electrode. The electrochemiluminescence ( ECL) signal could be greatly enhanced when the electrode was established by the nanocomposites, which finally resulted in the increased sensitivity. Glucose oxidase calalyzed the oxidation of glucose to form H2 O2 , and the H2 O2 reacted with luminol to produce the ECL signal. Thus the above system was proved to be efficient for glucose detection. The modified electrode exhibited excellent ECL signals and a good linear range of 1. 0í10-7-5. 0í10-6 mol/L with a detection limit of 5. 2í10-8 mol/L towards glucose detection. This strategy was successfully demonstrated as a sensitive, rapid, simple and cost-effective method to detect glucose. Meanwhile, the TiO2/CNTs nanocomposites offered a novel material for the signal enhancement in electrochemiluminescence sensor.
