Objective To investigate the clinical pathological factors related to recurrence and metastasis of colorectal cancer patients treated with resection ,expect to improve the treatment effects .Methods The clinicopathologic and follow-up data of 212 patients with stage Ⅰ - Ⅲ colorectal cancer patients treated with resection from January 2009 to December 2013 were retrospec-tively analyzed by univariate and multivariate Logistic regression methods .Results Univariate analysis showed that T staging sys-tems ,gross type ,intestinal obstruction or perforation ,lymphatic and vascular invasion were correlated to recurrence of colorectal cancer after operation(P< 0 .05) ;age ,tumor size ,lymph node involvement ,T staging systems ,histological differentiation ,intestinal obstruction or perforation ,lymphatic and vascular invasion were correlated to metastasis of colorectal cancer after operation(P <0 .05) .Multivariate Logistic regression analysis showed that age ,tumor size and histological differentiation were independent factors for metastasis rate of colorectal cancer after operation(P< 0 .05) .There were no significant differences in Logistic regression analy-sis for recurrence(P> 0 .05) .Conclusion Age ,tumor size and histological differentiation are independent factors for metastasis rate of colorectal cancer after operation .

Objective To investigate peoples' awareness degree and attitudes about organ donation in current China.Methods A questionnaire regarding organ donation was designed,including 20 little questions distributed in 10 groups,most of which were choice questions.The major question was people's attitudes on organ donation,and the development of organ donation.The survey was held in the outpatient hall,bustling commercial district and four professional colleges.The interviewees were randomly selected,and their gender,age,education background,profession or major filed were asked to be indicated on the paper.Results 2930 valid questionnaires were acquired in all.The proportion of men to women was nearly 1 ∶ 1.2,with mean age of 38.12 years old; more than 90％ of the interviewees knew organ transplantation,and could choose.some of the transplantable organs;more than 95％ knew organ donation,but the time varied; nearly 90％ of the interviewees approved cadaveric organ donation,and 73％ of them would like to donate their organs post mortem.People who know more about organ failure and organ transplantation can give more supports to organ donation.The young students have much enthusiasm to organ donation,but much professional knowledge is also needed to firm their attitudes.The approval percentage of living organ donation was 65.3％,obviously lower than cadaveric organ donation ( P ＜ 0.05 ).85.7％ of the interviewees approved to compensate the donators family appropriately.62.9％ suggested using media and various kinds of education to increase people's knowledge about organ donation,and only 20％ chose appropriate legislation.Conclusion At present,the public are aware of some general knowledge about organ transplantation and organ donation.Most of the public approve organ donation and would like to donate their organs post mortem.The popularization of organ transplantation can give facilitation to organ donation.Most of the interviewees believe appropriate compensation is necessary for the donator's family.Media and education can promote the development of organ donation.

Objective To study the roles of regulated upon activation normal T cell expressed and secreted(RANTES) and monocyte cbemoattractant protein-1 (MCP-1) in human immunodeficien- cy virus-1(HIV 1) infected patients.Methods RANTES and MCP-1 in HIV-1 infected patients, including treated and untreated groups,and healthy control group were determined by enzyme-linked immunosorbent assay(ELISA).The recombinant plasmids,hMCP-pcDNA3.1,bRANTES- peDNA3.1 and hMCP/bRANTES-pcDNA3.1,were constructed and transfected into CHO cells to overexpress the corresponding recombinant proteins,whose chemoattract function was then studied. Results The level of RANTES was (164.3?21.3) pg/mL in healthy control group,(1 224.1?62.0) pg/mL in untreated group and (475.3?36.2) pg/mL in treated group.The level of MCP-1 was (90.6?28.5) pg/mL in healthy control group,(335.0?30.3) pg/mL in untreated group and (807.2?62.6) pg/mL in treated group.In HIV-1 infected patients,the levels of RANTES and MCP-1 were significantly increased.After highly active antiretroviral therapy (HAART),the level of RANTES declined,but MCP-1 increased further.Western blot assay revealed that the three recombinant proteins could be recognized by monoclonal antibodies respectively.All of them could chemoattract human peripheral blood mononuclear cells(PBMCs).And the chemoattractant potency of MCP/RANTES fusion protein was stronger.When the recombinant proteins were used with con- centrations as 50,200,400 and 800 pg/mL,respectively,the number of PBMCs chemoattracted by MCP/RANTES fusion protein was 52?10~4/mL,102?10~4/mL,132?10~4/mL and 184?10~4/mL; the number of PBMCs chemoattracted by RANTES was 27?10~4/mL,51?10~4/mL,65?10~4/mL and 96?10~4/mL;the number of PBMCs chemoattracted by MCP-1 was 18?10~4/mL,44?10~4/mL, 54?10~4/mL and 74?10~4/mL.Conclusion RANTES and MCP-1 may both be involved in the HIV infection process and host immunological reaction against HIV.

Objective To investigate the clinical efficacy of treatment for chronic pancreatitis and mass in the head of the pancreas.Methods The clinical data of 19 patients with chronic pancreatitis with mass in the head of the pancreas who were admitted to the China-Japan Union Hospital of Jilin University from May 2008 to May 2013 were retrospectively analyzed,including 2 patients with gallstone.Methods of treatment were selected by in traoperative pathological results.All the patients were followed up by outpatient examination and telephone interview till January 2014.Results The operations of the 19 patients were successfully done,including 11 with pancreaticoduodenectomy,5 with exploratory laparotomy and 3 with the laparoscopic cholecystectomy and choledochojejunostomy.The operation time and intraoperative blood loss were (249± 140)minutes (50-390 minutes) and (320 ± 260)mL (50-900 mL).The postoperative mean time of recovery of gastrointestinal function and duration of postoperative hospital stay were 3.0 days (2.0-6.0 days) and 22.6 days (8.0-30.0 days) after the operation.The mean casein-IgG4 of 12 patients was higher (2.64 g/L) after operation.Five patients with operation-related complication were cured after symptomatic treatment,among 2 patients with leakage of the pancreatic fluid,2 with operative incision fat necrosis and liquefaction and 1 with bile leakage.No patients died perioperatively.Nineteen patients were followed up for 11.0 months to 36.0 months with the median time of 28.2 months.The pancreatic head mass of 8 patients with non-pancreaticoduodenectomy were reduced or disappeared by a computed tomography (CT) or magnetic resonance imaging (MRI) rescan,who were treated by the oral prednisone.No complications were detected in the other 11 patients with pancreaticoduodenectomy.Conclusion Method of surgery or medicine treatment for atypical mass in the head of the pancreas is selected according to the pathology results by effective communication with patients and family members,exploratory laparotomy and interpretative aspiration biopsy.

Objective To study the effect of hyperbaric oxygen(HBO)therapy on abilities of learning and memory and hippocampal pyramidal cell in vascular dementia rats.MethodsThe vascular dementia model was reproduced and divided into control,sham and treatment groups.After 30 d of HBO therapy,the rats were assessed with the Morris water maze,and their hippocampal pyramidal cells were observed after HE staining.ResultsCompared with the control group,the ability of learning and memory of rats in treatment group increased,as well as the hippocampal pyramidal cells did.ConclusionHyperbaric oxygen therapy can be used to treat vascular dementia.

OBJECTIVETo study the role of interleukin(IL)18 and interferon gamma (IFN-Gamma) in the pathogenesis of condyloma acuminatum(CA).

METHODSDouble antibody sandwich ELISA was used to measure the levels of IL-18 and IFN-Gamma in serum of 30 cases of CA.

RESULTThe serum levels of IL-18 and IFN-Gamma of the CA patients were significantly higher than those of normal controls IL-18 132.00 +/-52.92 microg/L compared with 50.79 +/- 23.48 microg/L, P<0.01 IFN-Gamma:80.83 +/-20.46 microg/L compared with 20.71 +/-11.18 microg/L P <0.01) and IL-18 levels were positively correlated with IFN-Gamma concentrations (r=0.754, t=6.081, P <0.01).

CONCLUSIONThese data suggest that during infection of human papilloma viruses, anti-infective immune responses are activated.
