The delta-shaped anastomosis is an emerging operation method in digestive tract reconstruction following total laparoscopic distal gastrectomy (TLDG).With the advantages of small surgical trauma,short anastomosis time and simple manipulation,it has been gradually accepted by surgeons.However,restricted by small manipulation range,restrictive visual range and large anastomotic lumen,there are controversies in complete resection of tumor,intraoperative indexes,postoperative recovery and prevention and treatment of complications about TLDG with delta-shaped anastomosis.In this paper,the operative indications,intraoperative indexes and postoperative recovery of TLDG with delta-shaped anastomosis were reviewed.

Objective To investigate the expression of tumor associated glycoprotein-72 (TAG-72) in human breast cancer cells. Methods Two breast cancer cell lines MCF-7 and Bcap-37 were cultured and prepared. TAG-72 expressions in MCF-7 and Bcap-37 were detected immunochemically with anti-TAG-72 single chain variable fragment (scFv). Results TAG-72 was positively expressed in MCF-7 cells but negatively expressed in Bcap-37 cells. Conclusion Tumor associated antigen TAG-72 is expressed in certain human breast cancer cells, which indicate TAG-72 may be used as a tumor maker and anti-TAG-72 scFv may play a role in the diagnosis and treatment of breast cancer.

Objective To construct a mammalian vector encoding angiostatin kringle 5 (K5) under the control of ?-fetoprotein (AFP) enhancer and albumin promoter, and to observe the expression of angiostatin by introducting angiostatin gene into hepatocellular carcinoma cells through gene transfection. Methods Angiostatin cDNA was amplified from normal human eukaryotic cells by using RT-PCR. Meanwhile, AFP enhancer and albumin promoter sequences were directed cloned and were inserted into vector pcDNA3.1. The recombinant vector of pcDNA3.1-AFAB-angiostatin K5-His was constructed, which contained the angiostatin K5 cDNA sequence that was under the control of the AFP enhancer and promoter. Angiostatin K5 cDNA was introduced into human AFP positive hepatocellular carcinoma cell lines with the transfected cultured cells that were mediated with Lipofectamine 2000. The expression of angiostatin K5 was analyzed by Western blot and the protein was dectected with anti-His antibody. Results The 500-base pair of angiostatin K5 was in accordance with the expected sequence and the recombinant vector of pcDNA3.1-AFAB-angiostatin K5-His was also confirmed as the anticipated sequence. The expression of angiostatin K5 in AFP positive hepatocellular carcinoma cells was detected both by SDS-PAGE and Western blot. Conclusion Efficient construction and expression of angiostatin K5 to AFP positive cells make it possible for antiangiogenesis therapy of human hepatocellular carcinomas, which may provide a promising approach.

Objective To study the feasibility and safety of laparoscopy-assisted D2 radical gastrectomy for advanced gastric cancer. Methods From June, 2006 to July 2009, 11 patients with gastric cancer received laparoscopy-assisted gastrectomy for gastric cancer. According to UICC TNM classification of gastric cancer, 6 cases were with Stage Ⅱ, 2 cases with Stage Ⅲ A, 1 case with Stage Ⅲ B, and 2 cases with Stage Ⅳ. Under the assistance of laparoscope, dissociation of the stomach and lymph nodes clearance were performed first; then gastrectomy was performed on a 6 cm incision, samples were collected, and alimentary tract was inoculated. Results Among the 11 cases, 2 cases were performed radical total gastrectomy, 1 case was performed proximal partial gastrectomy, 7 cases were performed distal partial gastrectomy and 1 case with open surgery. The mean operation time: 350 min for total gastrectomy, 320 min for proximal partial gastrectom,266 min for distal partial gastrectomy. The mean number of harvested lymph nodes was 21.3 (11-38), incisal edge was 5.6 (4.0-9.6) cm. The mean time was 72 (36-110) hrs for gastrointestinal function recovery, 59 (26-86) hrs for patients to take general activity, and 76 (48-116) hrs to take liquid food. No complication was observed. Conclusion Laparoscopy-assisted D2 radical gastrectomy for advanced gastric cancer is safe and feasible. Compared with open surgery, it also has the advantages of small wound and fast recovery.

AimTo establish a model of the injury of the vascular endothelial cell(VEC) in rats and observe the function of Chinese herbs of Li Qi Huo Xue(LQHX) will prevent and treat the VEC injury. Methods30 SD rats weredivided into the control, the model and LQHX groups. The model of the VEC injury was established. It tried to demonstrate the effect of LQHX for the coagula tion and fibrinolysis function of the VEC by the C EC count,t-PA, PAI activity, 6-keto-PGF1αcontent and PAgTmax. Results In LQHX group as compared with those of the medol group, The CEC count was redued obviously(P＜0.01). t-PA activity was increased(P＜0.01), so did the percentage of active t-PA(P＜0.01), but PAI activity decreased (P＜0.05), 6-keto-PGF1α content increased (P＜0.01)α the PAgTmax decreasd (P ＜0.01) Conclution LQHX can enhance the anticoagulation and fibrinolysis activities. It is a more effective measure for the VEC protection.

The HL-60 cells were transfected with chk1 antisense and sense chain, and 24 h later subjected to irradiation. Twenty-four h after irradiation, the changes in the chk1 protein expression was assayed by Western blot, and the cell cycles and apoptosis rate detected by FCM. The irradiated apoptosis sensitivity was increased by antisense blocking of chk1 gene in HL-60 cell line with the apoptosis rate being 26.31%, significantly higher than that by the sense blocking (10.34%, 0.025 < P < 0.05). In HL-60 cells transfected with chk1 antisense chain, the G2/M phase arrest was attenuated and the cells in G2/M phase were accounted for 38.42%, significantly lower than those of the cells transfected with chkl sense chain (54.64%, 0.005 < P < 0.01). It was concluded that antisense blocking of chk1 gene could increase the apoptosis sensitivity to irradiation.

BACKGROUND:Evaluation of vertical jumping ability is usual y only limited to height measurements. The measurements of parameters that describe kinetic factors may provide a better assessment of a patient’s jumping ability.
OBJECTIVE:To determine the deficit in one-legged vertical jumping ability and to clarify the relationships between the maximum jumping height and the maximum power, force and velocity during one-legged vertical jumps after anterior cruciate ligament reconstruction.
METHODS:Twenty-five healthy subjects (10 males and 15 females) and 25 anterior cruciate ligament reconstructed patients (10 males and 15 females) participated in this study. The isokinetic quadriceps femoris strength and one-legged vertical jumping ability were evaluated by the height, power, force and velocity in al subjects.
RESULTS AND CONCLUSION:(1) The maximum height of the one-legged vertical jumps was only significantly correlated with the maximum force in the healthy subjects (P<0.05). (2) However, for the reconstructed and unreconstructed legs in anterior cruciate ligament reconstructed patients, the maximum jumping height was significantly correlated with the maximum power, force and velocity during one-legged vertical jumps (P<0.05). (3) These findings suggest the importance of a knee strategy during one-legged vertical jumps for rehabilitation after anterior cruciate ligament reconstruction. Assessment of the jumping ability after anterior cruciate ligament reconstruction may be determined by the maximum power instead of the maximum jumping height.
