Laparoscopic hepatectomy has been utilized in clinic,however to some extent there are some limitations for various equipments being used in laparoscopic hepatectomy, as a result, the laparoscopic bepa-tectomy is being constrainted on its development. Therefore, with the research and development of the ideal tool for laparoscopic hepatectomy,laparoscopic liver surgery is bound to be booming.

Secondary lymphoid tissue chemokine (CCL21) is a double-edged sword, which exerts antitumor, anti-infection immune response by binding to the receptor CCR7 on the surface of the multiple immune cells. However, a variety of tumor cells also express the receptor CCR7, the combination of CCL21 with CCR7promotes the invasion and metastasis of tumor cells, leading to the facilitation of tumor development. Therefore,exploring the mechanism(s) of tumor invasion and metastasis might be helpful for use of CCL21 as tumor gene therapy through blocking of CCL21's promotion of tumor invasion and metastasis.

0.05).Thirty-four cases of newly diagnosed children with CR rate was 88.2% (30 cases).Which the expression of PRAME gene,WT1 gene were both positive and negative groups of children with CR rates were 62.5% and 100.0%,there was no significant difference between the 2 groups(P

OBJECTIVE:To compare the effects of total knee arthroplasty performed with and without patellar resurfacing. METHODS:All randomized clinical trials relevant to comparison of total knee arthroplasty performed with and without patellar resurfacing between 1966 and 2008 were collected. The quality of the trials was assessed. The outcomes data including the prevalence of reoperations,postoperative anterior knee pain,patient satisfaction,and the improvement in various knee scores were extracted and reviewed systematically. RESULTS:1 731 knees were included in the 15 published trials,including 842 knees in the resurfaced group and 889 in the nonresurfaced group. During the four years following surgery,there was no significant difference between the resurfaced and the nonresurfaced groups in re-operation rate (relative risk=0.56,95% CI 0.17-1.85); whereas the re-operation rate of the nonresurfaced group was significantly greater than resurfaced group 4 years after surgery (relative risk=0.46,95% CI 0.25-0.84). On the prevalence of postoperative anterior knee pain,there was no significant difference between two groups (relative risk=0.65,95% CI 0.35-1.21). No significant difference was found in patient satisfaction (relative risk=1.00,95% CI 0.95-1.05). There was no significant difference between the resurfaced and the nonresurfaced groups in the KSS scores (weighing mean difference:-0.41; 95% CI:-3.08 to 2.26). CONCLUSION:The long-term rate of reoperations in total knee arthroplasty performed with patellar resurfacing was lower than that without patellar resurfacing. There were no significant differences in the terms of prevalence of postoperative anterior knee pain,patient satisfaction,and the improvement in various knee scores between the resurfaced and the nonresurfaced groups. The results of this systematic review should be explained prudently because of some limitations of included trials. For more reliable conclusions,more trials with high quality on methodology are needed.

BACKGROUND: Mesenchymal stem cells, a kind of popular seed cells for cell transplantation after myocardial injury, have become a hot research topic in the treatment of ischemic heart diseases. OBJECTIVE: To review the new progress of mesenchymal stem cell transplantation in the treatment of ischemic heart diseases. METHODS: We searched Medline, Ovid Embase, PubMed Central, Cochrane Library, Chinese Periodical Full-Text Database, Chinese Biomedical Literature Database, VIP database, Wanfang Database for relevant articles in Chinese and English languages, and the retrieval time was from 1985 to 2015. Articles related to randomized controlled trials or clinical research on mesechymal stem cell transplantation for treatment of ischemic heart diseases were included, and relevant review were also included. Observational studies, casereports, study protocols with no standard or rational design, reviews with no normative and rigorous inclusion criteria, cross-test studies, cluster randomized trials, and studies that have nothing to do with the topic were excluded.RESULTS AND CONCLUSION: Through literature screening, we summarize the research progress in the mesenchymal stem cell transplantation, including cell source, safety, efficacy, action of mechanism and injection mode, and analyze the merits and demerits of mesenchymal stem cell transplantation. Bone marrowmesenchymal stem cell transplantation provides a new insight into the clinical treatment of myocardial infarction,but there are still many problems to be solved, such as cell quality, cell dose, transplantation mode, transplantation timing and patient selection, which so limit the clinical application of mesenchymal stem cell transplantation.

Circulating tumor cells (CTCs)are special kind of tumor cells in the peripheral blood of patient with tumor.Now CTCs detection has been used in the survival time prediction,post-operational recu-rrence detection,individualized treatment and other aspects in the patients with gastric cancer.As the research going,CTCs will provide new help for the comprehensive treatment of gastric cancer.

Reducing blood loss during hepateetomy is important.Intraoperative blood loss and liver damage of hepatectomy under the total hemihepatic vascular exclusion could be less than that under the other methods of vascular occlusion.It could be worth improving and applying further.This article review the latest studies to introduce the latest advancement in this area.
