Objective To compare the applicability of the 7th and 6th editions of the UICC-AJCC esophageal cancer TNM staging systems for adenocarcinoma of esophagogastric junction (EGJ).Methods During June 2007 through December 2010,199 patients with EGJ adenocarcinoma(Siewert type Ⅱ) underwent R0-intent resection in our hospital.Their clinicopatholigical and survival data were retrospectively analyzed with Kaplan-Meier and Cox regression models.They were restaged according to the 7th and 6th UICC/AJCC TNM staging systems for esophageal cancer,respectively.Then the Akaike information criterion(AIC) was used for measuring goodness of fit of both staging systems.Results Among 199 patients,there were 162 males and 37 females.Univariate analysis indicated that age(P =0.009),surgical approach(P =0.002),cell differentiation (P =0.030),preoperative co-morbidity (P =0.026),depth of tumor invasion (P ＜ 0.000) and number of metastatic lymph nodes(P ＜ 0.000) were significant influencing factors on overall survival.Multivariate analysis demonstrated that the independent prognostic factors for EGJ adenocarcinoma were age,T stage,N stage and preoperative co-morbidity according to the 6th edition of esophageal cancer TNM staging system,and only T stage,N stage and preoperative co-morbidity according to the 7th edition of esophageal cancer TNM staging system.The AIC value was 961.4 for the 7th edition of esophageal cancer staging system and 972.4 for the 6th edition.Conclusion The 7th edition of UICC/AJCC esophageal cancer TNM classification is su perior to its 6th edition of esophageal cancer staging system for EGJ adenocarcinoma.

Objective To evaluate the antitumor effect of corosolic acid and its impact on CAM and YSM angiogenesis.Methods The effects of CRA on A549 proliferation was studied by MTT method in vitro.Tumor-bruden nude mice model were established by injecting A549 lung cancer cell marked with bioluminescent to nude mice,and the growth of tumor in mice were detected by IVIS small animal in vivo imaging system.Experiment of chicken embryos eggs are used to observe the role of drugs on CAMand YSMblood vessels. Results The value of IC50 of CRA for A549 in vitro was 26.8μg/mL.A tumor-burdened animal experiment results showed that the CRA to A549 solid tumor has a certain therapeutic effect.CAM and YSM blood vessels of chicken embryos eggs treated with CRA were decreased significantly than negative control group.Conclusion CRA has certain therapeutic effect for A549,which may be related to the inhibition of angiogenesis in tumor tissues.

Objective To compare the therapeutic effects and side effects of cisplatin-S-1 (CS) program and docetaxel-cisplatin-S-1(DCS) program on patients with malignant gastric tumor who were treated by laparoscopic gastrectomy.MethodsA total of 67 patients in our hospital from January 2010 to June 2013 were included in this study,of which 33 cases accepted cisplatin-S-1 program (CS group),34 cases accepted DCS program (DCS group).The related side effects including diarrhea,nausea and acute upper respiratory infection,change of routine blood tests,blood biochemical index,and death caused by chemotherapy were analyzed.The related index of surgery including operation time,blood loss,recovery time of gastrointestinal function,pain incidence,hospital stay,lymph nodes resection success rate,postoperative infection,obstruction,intestinal emptying delays were recorded.Meanwhile,the 3-year survival rate after operation and postoperative 3-year recurrence rate between the two groups were compared.Results There was no significant difference in operation time,intraoperative blood loss,postoperative recovery time of gastrointestinal function,the lymph nodes resection success rate,the incidence of postoperative pain,as well as the length of hospital stay,postoperative infection rate,and complications such as obstruction and intestinal emptying delays between the two groups(P>0.05).And there was no significant difference in chemotherapy-related complications between the two groups(P>0.05).But the postoperative 3-year survival rate and postoperative 3-year recurrence rate of DCS group was better than those of the CS Group(P<0.05).Conclusion There is no significant difference in complications and surgery-related index between the two preoperative chemotherapy.However,the DCS programs have more advantages in therapeutic effects.

BACKGROUND:In recent years, tissue engineering has made great progress, and skin tissue engineering is especialy noteworthy. Artificial dermis (PELNAC) is relatively used widely, but there is a lack of relevant reports on wound repair in children. OBJECTIVE:To investigate the clinical efficacy of Pelnac? METHODS:In a retrospective study, 22 patients with the wound of severe trauma were treated with Pelnac as skin graft dressings on treatment of the wounds of severe trauma in children. ? graft, negative-pressure wound therapy and split-thickness skin graft as experimental group (Pelnac? group), and another 19 patients treated with granulation formation dressing and split-thickness skin graft as control group. We colected data including the graft livability, the required re-operative times and the epithelization time after the skin graft. During the folow-up, the skin color and texture of survival skin, subcutaneous fulness, scar hyperplasia and the joint function were also evaluated. RESULTS AND CONCLUSION: In the Pelnac ? group, the graft livability was up to 90% within 10-14 days after grafting. The secondary split-thickness skin graft was required in two cases in the Pelnac? group and in eight cases in the control group. There was a significant difference in the graft livability (P < 0.05). The average epithelization time after the skin graft was (13.86±3.09) days in the Pelnac? group, which was significant shorter than the control group, (19.10±4.62) days, after the first time operation (P< 0.05). During the 10 months folow-up, the survival skin color and skin elasticity in the Pelnac? group was significantly better than that in the control group (P< 0.05). Better subcutaneous fulness and milder scar hyperplasy in the injured sites were obtained in the Pelnac? group compared with the control gorup. Five cases had certain joint function limitation in the Pelnac? group, compared to 10 cases in the control group, with a significant difference (P < 0.05). Artificial dermis Pelnac? has a stronger anti-infectious ability and higher graft livability. Pelnac? graft combined with negative-pressure wound therapy, granulation culture and split-thickness skin graft can shorten the epithelization time, improve wound healing and aleviate harm to the joint function after the skin graft.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.
