Objective To detect the expression of Livin in gastric cancer tissues and cells, and investigate its relation to tumorigenesis and progression of gastric cancer cells. Methods (1) The expression of Livin in gastric cancer tissues was located by immunocytochemisty. (2) Livin mRNA and protein expression in adjacent tissues of carcinoma, gastric ulcers and gastric cancer tissues were detected by RT-PCR and Western blot. Results The expression of Livin in the nucleus and cytoplasm of gastric cancer cell line SGC-7901 was observed. The positive rate of Livin expression in the gastric cancer tissues was 67% (20/30). There were no expression of Livin-α and Livin-β in the adjacent tissues of carcinoma and the gastric ulcers. The positive rate of Livin-α expression in the gastric cancer tissues was positively correlated with TNM stage of gastric cancer (x2=11.719, P<0.05). The expression rate of Livin in the differentiation and location of gastric cancer, age and gender of patients had no statistical difference (x2=1.607, 0.000, 0.156, 0.419, P>0.05). Conclusion Correlation of high Livin-α expression and pathologic staging of gastric cancer indicates that Livin-α may play an important role in the carcinogenesis and progression of gastric cancer.

Objective To study the relationship between the changes of TRIM16 in hippocampus of type 2 diabetic rats induced by streptozotocin (STZ) and cognitive dysfunction and apoptosis of hippocampal cells.Methods The male Sprague-Dawley (SD) rats of 8 weeks old were randomly divided into diabetic group (DM group) (n=25) and normal control group (NC group) (n=15).NC group were given normal feed, DM rats were fed with high glucose and high fat diet,followed by low dose of STZ (25 mg/kg, intraperitoneal injection), induced compensatory secretion of insulin, five days after the detection of tail vein blood glucose>16.7 mmol/L, and established the STZ.Meanwhile, citric acid buffer was injected to rats in group as control.After successful modeling, the rats in the two groups were fed with 17 weeks.Morris water maze test was used to detect the cognitive function of the two groups of rats.The protein expression of TRIM16, Bax and Bcl-2 protein in fresh hippocampus tissue of DM group and NC group rats was detected using western blotting.Rats in DM group and NC group were perfused with brain, and the hippocampal tissues were stained with immunohistochemistry.TUNEL method was used to detect the apoptosis of hippocampus cells.ResultsCompared with NC group, morris water maze test showed that the escape latency of rats in DM group is longer than NC group, staying at the original platform quadrant time in DM group is less than the NC group.TUNEL assay showed that after injection of 17 weeks, hippocampal CA1 pyramidal cells in type 2 diabetic rats appeared obvious apoptosis, positive neurons in the nuclei were brown, karyopyknosis anachromasis, while control group of neurons in the nucleus without brown coloring.Compared with the NC group, hippocampus immunohistochemistry results showed that the protein of TRIM16 in hippocampus CA1 region of type 2 diabetic rats was increased, cytoplasm brown, coarse granular.Compared with the NC group, the expression of Bcl-2 had no obvious change in hippocampus of type 2 diabetic rats at 17 weeks, while the expression of TRIM16, Bax and the ratio of Bax/Bcl-2 was significantly increased (P<0.05).Conclusion The protein expression of TRIM16 using immunohistochemical and Western blotting in hippocampus of diabetic rats induced by STZ was increased.There is apoptosis in hippocampus of diabetic rats induced by STZ, the expression of Bcl-2 was not significantly changed, the expression of Bax and the ratio of Bax/Bcl-2 were significantly increased.TRIM16 is involved in diabetic cognitive dysfunction by promoting apoptosis of diabetic rat hippocampus.

The authors give an account of their guiding ideology, implementing methods and practical experience in setting up research funds for nursing. Their experience is as follows. Establishment of the funds in their hospital has played a positive role in promoting research on nursing. Greater increase in intellectual input and creation of a sound environment for the conduction of research on nursing is an effective guarantee for the successful conduction of the work. Emphasis has been rightly put on clinical projects by orienting the research funds towards projects involving clinical nursing. And making a good job of the whole nursing procedure is the key to the proper application of the research funds for nursing. Besides, to give full play to the role of research funds for nursing, it is imperative to cultivate academic leaders in nursing able to keep abreast of the times, aim closely at the frontier research in the field and bring into effect the starting and catalytic action of research funds for nursing.

Objective To evaluate TriVex based transilluminated powered phlebectomy (TIPP)three-stage management for lower limb venous ulcers.Methods This retrospective study included 86 patients with 103 diseased limbs treated in our hospital from October 2005 to July 2013.All received TriVex TIPP three-stage management.Results After therapy there was no acute cellulitis,skin necrosis nor lower limb deep venous thrombosis.There were 2 cases of subcutaneous ecchymosis,1 case of subcutaneous hematoma,1 case of skin abnormal sensation and 1 case of subcutaneous induration.Ulcers healed within one month postoperation in all cases,while skin abnomalities were alleviated with no ulcer recurrence during the follow-up ranging from 4 to 48 months.Conclusions TriVex TIPP centered threestage management is a good option for lower limb venous ulcer,with shortened healing time,low recurrence rate.

Objectives To observe the effects of varied doses of L-thyroxin sodium ( L-T4) on congenital hypothyroidism ( CH) and to determine appropriate dose for early therapeutic intervention. Methods Totally, 108 cases of confirmed CH were divided into two groups (54 in each group). All the cases were administered with L-T4 at varied doses( 10. 1? - 15. 0 ?g ? kg-1? d-1 for large-dose group and 6. 0 - 10. 0 ?g ?kg-1? d-1 for small-dose group) after their parents were trained for basic knowledge of CH by specialists. Their serum levels of T3, T4 and TSH, as well as their body height, weight and head circumference, were measured during follow-up. L-T4 was maintained at doses of 1. 0 - 4. 0 ?g ? kg -1 ? d-1 when their serum levels of T3, T4 and TSH returned to normal. Results All the 108 cases had their clinical symptoms quickly improved and development and growth accelerated after L-T4 substitution. Their serum level of T3 returned to normal in all cases, that of T4 did not return to normal in six cases of large-dose group and in 16 cases of small-dose group, and that of TSH did return to normal in 22 cases of large-dose group and in 39 cases of small-dose group, respectively, after one-month treatment, with a significant difference between the two groups. Cases in large-dose group gained more weight in average than those in small-dose group when they were three months old. Conclusions Early therapeutic intervention for babies with CH with L-thyroxin sodium of 10. 1 -15. 0 ?g ? kg-1? d-1 could quickly correct abnormal function of their thyroid and could avoid abnormal development of their intelligence due to CH.

AIM　To elucidate the structure of the glycan of SPPA-1, a glycoconjugate isolated from Spirulina platensis. METHODS　Methylation analysis, GC/MS, and 1D, 2DNMR techniques were used to determine the structures of the glycoconjugate (SPPA-1). RESULTS　SPPA-1 was only composed of α-D-glucose and shown to be a (1→4) linked α-D-glucan to which a few glucosyl side chains are attached at O-6 of the glucosyl residues of the main chain. CONCLUSION　The glycan of SPPA-1 is a new glucan.

AIM　To determine the effects of glycoconjugates and their glycans from Lycium barbarum L. on inhibiting low density lipoprotein (LDL) peroxidation. METHODS　Using Cu2+-induced oxidation as a model, the oxidative production of thiobarbituric acid-reactive substances (TBARS) and the LDL electrophoresis migration on agarose gel were measured. RESULTS　The effects of glycoconjugates and their glycans from Lycium barbarum L. on inhibiting LDL peroxidation were different, among them, glycoconjugate LbGp5 showed the best effect on inhibiting LDLperoxidation. CONCLUSION　The glycoconjugates can inhibit LDL peroxidatin while their glycans showed no effects on inhibiting LDL peroxidation.
