ABSTRACT
Objective To study the the feasibility of intestinal derotation maneuver in the resection of gastrointestinal neoplam localized in the vicinity of the ligament of Treitz.Method Intestinal derotation maneuver was applied in all the 9 case of gastrointestinal neoplasms near the ligament of Treitz,from January 2014 to January 2016,at the Second Hospital of Jilin University.The clinical date were retrospectively analyzed.Results Intestinal derotation maneuver were applied without failure in all the nine patients,the mean operation time were (195 ± 50) min,and the mean intestinal derotation maneuver time were (19 ±5) min;No derotation procedure-related injury occured,and the mean estimated blood loss were (132 ±94) ml.Early postoperative ileus developed in one case and gastroparesis in two cases.All were recovered by conservative treatment.The follow-up period were 3-24 month,tumor recurrence occurred in two cases and one case died.One case lossed to follow-up after postoperative 3 month.Conclusion The present data suggest that clinical use of intestinal derotation maneuver was feasible for surgical management of gastrointestinal neoplasms near the ligament of Treitz.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical advantage of the application of modified Roux-en-Y reconstruction after totally laparoscopic total gastrectomy.</p><p><b>METHODS</b>Clinical data of 36 patients who underwent totally laparoscopic total gastrectomy with Roux-en-Y reconstruction by one medical team for gastric adenocarcinoma between January 2014 and December 2014 in the Second Hospital of Jilin University were retrospectively analyzed. Patients were divided into classic Roux-en-Y group (CRY, 16 cases) and modified Roux-en-Y group (MRY, 20 cases) according to reconstructive methods. The data concerning the intraoperative and postoperative situation in two groups were compared.</p><p><b>RESULTS</b>Operation was successfully completed in all the cases without conversion to laparotomy. Compared to CRY group, MRY group had shorter mean operative time [(260.9 ± 21.2) min vs. (287.9 ± 19.0) min, P=0.000], shorter mean reconstruction duration [(32.4 ± 9.2] min vs. (45.4 ± 13.2) min, P=0.001] and less intraoperative bleeding [(50.9 ± 23.5) ml vs. (67.0 ± 20.5) ml, P=0.000]. Jejunum mesentery dissection and jejunum resection were not necessary in MRY group. However, there were no significant differences in lymph nodes harvested, time to flatus, hospital stay and postoperative complications between two groups.</p><p><b>CONCLUSIONS</b>As compared to classic Roux-en-Y reconstruction, the modified Roux-en-Y reconstruction can simplify the surgical procedures and achieve similar efficacy. It is feasible and safe, and worth further promotion in clinical practice.</p>

Objective To study the effect of Ro60 on migration and invasion of lung adenocarcinoma A 549 cells. Methods We knocked down Ro60 and analyzed the ability of migration and invasion of A 549 cells.Quantitative real time ( RT)-PCR and Western blotting were performed to detect mRNA and protein levels of selected molecules associated with migration and invasion of neoplasm .Results When Ro60 was downregulated , the migration and invasion of A 549 cells decreased markedly.Meanwhile,the mRNA expression of matrix metalloproteinase (MMP)9,c-Src etc was observably reduced.Furthermore, downregulation of Ro60 diminished the expression of Src protein and the activation of MMP-9 protein.Conclusion Downregulation of Ro60 inhibits migration and invasion of A549 cells by regulating Src protein and activating MMP-9 protein.
ABSTRACT
Objective To evaluate the safety and reliability of laparoscopic in treatment of gastric gastric stromal tumor (GST).Methods 48 GST patients were selected for laparoscopic operation who had no distant metastases,adjacent organ invasion and non-cardia and pylorus infiltration confirmed by preoperative examination.The postoperative treatment,follow-up and the effect was observed.Results 48 patients included 22 males and 26 females,and mean age was 56 years old.The tumor diameter was 0.6-10.0 cm,in which 36 cases had tumor size ≥ 2 cm.12 cases of tumor occurred in gastric antrum,12 cases in gastric fundus,16 cases in anterior wall of gastric body,8 cases in posterior wall of gastric body.The mean operative time was 85 min,the mean operation blood loss was 65 ml,the postoperative average start eating time was 3 d,and the mean postoperative in-patient time was 7 d.All patients were followed up for 12-36 months.There were no local recurrence and distant metastasis and tumor-related deaths.Conclusions For the GST patients who have no distant metastases,adjacent organ invasion and non-cardia and pylorus infiltration,laparoscopic operation is safe and effective,which is not only applied to less than 2 cm diameter GST,but also to larger diameter tumor.
