Chinese Journal of Digestive Surgery 2008;7(3):177-179
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.

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.

BACKGROUND:It remains controversial in term of efficacy for the lightweight mesh and heavyweight mesh in inguinal hernia repair.
OBJECTIVE:To compare the clinical therapeutic effects of lightweight mesh and heavyweight mesh in open methods of inguinal hernia repair with Meta-analysis.
METHODS:Comprehensive electronic search strategies were developed using the fol owing electronic databases:PubMed, Cochrane Library, EMBASE, Medline, Ovid, CNKI, VIP, Wanfang and FMJS. The Literature published before February 2013 was searched. The randomized control ed trials about comparing lightweight mesh and heavyweight mesh in open methods of inguinal hernia repair were included. A data-extraction sheet was developed based on the preset standards. The data from eligible studies were pooled using RevMan5.1 software through Meta-analysis.
RESULTS AND CONCLUSION:Eighteen trials with a total of 4 450 hernias met the inclusion criteria. The meta-analysis showed that there was a statistical difference between lightweight mesh group and the heavyweight mesh group on short-term pain [odd ratio (OR)=0.57, 95%confidence interval (CI) (0.43, 0.74), P<0.05] and a reduced risk of developing foreign body sensations [OR=0.49, 95%CI (0.35, 0.69), P<0.05]. No significant differences were found between the two groups in recurrence rate, testicular atrophy, seroma, hematoma, wound infection, urine retention (P>0.5). According to limited evidence, there are some findings as fol ows:the lightweight mesh is of feasibility, safety and effectiveness for inguinal hernia repair. Because of the limits of sample and quality, more large-sample and high-quality trials are required to make a definite clinical evidence to use lightweight mesh for inguinal hernia repair.
