Golgi protein 73, a novel Golgi-localized transmembrane glycoprotein , is normally expressed in biliary epithelial cells of human tissues.Researches show that GP73 is overexpressed in many tumor tissues, such as hepatocellular carcinoma , prostate cancer, lung adenocarcinoma, renal cell cancer, and so on, which may play on important role in cancer diagnosis as a novel tumor marker.

Objective To explore the effects of dignity therapy on self-esteem status and negative emotions of lung cancer patients.Methods A total of 62 lung cancer patients were recruited and divided into experimental and control groups (n =31 each).The control group received routine care while the experimental group additional individualized dignity therapy.And the state self-esteem scale,self-rating anxiety and self-rating depression were used to evaluate the intervention outcomes.Results For both groups,the self-esteem status and negative emotions of the intervention group were significantly better than that those of the control group (self-esteem:61.2 ±4.6 vs.52.6 ±4.1,anxiety:52.2 ±6.8 vs.64.6 ±9.3,depression:51.1 ±7.9 vs.66.2 ±8.7,all P ＜0.05).Conclusion Dignity therapy can improve selfesteem status,decrease the levels of anxiety and depression level and boost quality of life for lung cancer patients.

Objective To explore the relationship of neutrophil and interleukin-8(IL-8)with exercise-induced asthma(EIA).Methods From May 15,2001 to Dec 19.2005 the levels of peripheral neutrophil superoxide anion and IL-8 in the blood and the induced sputum from patients with EIA,non EIA and normal control subjects were measured respectively before and after exercises,meanwhile a comparison was made among them.Results Before exercise:the level of neutrophil superoxide anion was slightly higher in EIA group and non EIA group than that in control group;however,the differences were insignificant;the IL-8 and MDA levels in blood and induced sputum were higher in EIA group and non EIA group than those in control group,but there was no significant difference between EIA group and non EIA group;however,they were significantly different between EIA group and control group,non EIA group and control group respectively( P 0.05).Conclusion Oxyradical produced by neutrophil and IL-8 has significant effect on the production of EIA.

Objective To study the variables of behavioral function and TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) figure in Bcl-2 transgenic (TG) mice and control mice after spinal cord injury (SCI), thus to find new ideas and ways for diagnosing and treating SCI. Method The genesis of Bcl-2 overexpression transgenic (TG) mice were produced by injection of Bcl-2 plasmid into the fertilized ova of mice.Nine Bcl-2 TG mice and nine control mice were subjected to SCI of moderate severity at T10, with the use of weight dropping (WD) method (impact force 2.5～3.0 g·cm). Up to 1 day , 7 days, and 14 days after SCI,functional deficits were evaluated with BBB scales, and the apoptosis of neurons was investigated by using TUNEL method. Another three mice of control group were only treated with laminectomy without SCI for comparison. Results The mean functional scores in the control mice were lower than those in the Bcl-2 TG mice, although the unpaired T -test revealed no significant differences. On the other hand, the number of TUNEL positive neurons and IOD(Integrated Optical Density)score in the Bcl-2 TG mice were both significantly lower than those in the control mice. Conclusions This experiment suggests that overexpression of Bcl-2 may suppress neuronal apoptosis after SCI. The Bcl-2 may be an important factor in relieving the damage within CNS after trauma.

Objective to evaluate the impacts of 6 standard comparible tables of biparietal diameter(BPD)-gestational age to the second trimester Down syndrome screening and the individual risk rate for pregnant woman. Methods A total of 25 346 pregnant woman with gestational age be-tween 12 to 20 weeks were recruited and analyzed in the study,including 32 Down syndrome. For each pregnant woman,we calculated the gestation-al age by six different BPD-gestational age tables,and the prenatal screening risk value of gestational age. then ROC curve,detection rate and posi-tive rate were used to evaluate the effect of different control tables on the screening results. In addition,individual risk rate was used to determine the influence of gestational age deviation on pregnant woman. Results According to the ROC,we found that our self-designed BPD table had the best AUC(0.972),while the table designed by a hospital in Shanghai had the least AUC(0.923). the difference was significant by statistic test(P =0.045). With the same detection rate of 75%,we found our self-designed table had the least positive rate with only 2.3%,and the cutoff was 1∶280, while the table of Chinese Obstetrics and Gynecology had the highest ratio(4.8%),and the cutoff was 1∶345. Our results suggest that once gesta-tional age is estimated to be higher than actual age,the risk will be higher and the positive rate will increase. However,if gestational age is estimated to be smaller,the risk will be smaller and the negative rate will increase. Conclusion the impacts of different tables on Down syndrome screening are different. Our self-designed BPD table is the most effective to estimate gestational age,and the control table of Hongkong is ranked No.2. the wrong estimation of gestational age will largely affect the individual risk of pregnant woman.

Objective To evaluate the effect of oral mesalazine combined with metronidazole enema in the treatment of patients with ulcerative colitis and the impact on interferon-γ (IFN-γ),interleukin-4 (IL-4),interleukin-8 (IL-8).Methods A total of 80 patients with ulcerative colitis were selected and randomly divided into control group and observation group,40 cases in each group.The control group was treated with oral mesalazine.The observation group was treated with oral mesalazine and metronidazole retention enema.4 weeks as a course of treatment,the patients were treated for 2 courses.The clinical efficacy,disease activity index(DAI) score before and after treatment,as well as peripheral blood erythrocyte sedimentation rate (ESR),levels of IFN-γ,IL-4,IL-8 changes was compared between the two groups.Results The total effective rate was 90.00％ in the control group,which was significantly higher than 75.00％ in the control group,the difference was statistically significant (x2 =23.52,P ＜ 0.05).Before treatment,there were no significant changes in diarrhea,colonic mucosal inflammation,bloody stool and DAI scores (t =0.32,0.08,0.03,0.05,all P ＞ 0.05).After treatment,there were significant decline in each integral of the two groups,the integral of the observation group declined more than those in the control group,the differences were statistically significant(t =15.35,5.8,11.25,14.12,all P ＜0.05).Before treatment,there were no significant changes in ESR,IL-4,IL-8,IFN-γ of peripheral blood in the two groups (t =0.60,-0.95,0.03,-0.06,all P ＞ 0.05).After treatment,ESR,IL-8,IFN-γ of peripheral blood declined in the two groups,IL-4 was increased,and the changes were more significantly in the control group than those in the control group(t =10.02,4.70,10.23,22.82,all P ＜ 0.05).Conclusion Oral mesalazine enema combined with metronidazole enema has significant clinical effect in patients with ulcerative colitis,it is better than treating with oral mesalazine only,and can effectively improve the clinical symptoms and possibly plays a role by regulating IL-8,IFN-γ,IL-4,and it deserves further clinical application.

To test the hypothesis that dermal fibroblasts (DF) are an important source of cytokines which elicit major changes in hepatic synthesis of acute phase reactants(APRs). Metkods: Condi-tioned medium(CM) from human DF challenged with bacterial lipopolysaccharide (I,PS) was collected andIL-10 and IL-6 levels were measured- The ability of DF conditioned medium(fLPS) and dexamethasone(Dex) to mediate an hepatic acute phase response was tested on rat hepatoma H4 cells- Various concentra-tions and combinations of CM (?LPS), recombinant IL-6 (rhIL-6) and Dex were tested for their abilitiesto stimulate albumin, Q,-acid glycoprotein (AGP), a,-antitrypsin (AT) and transferrin mRNA synthesis.Results: LPS stimulated IL-6 production by DF and Dex inhibited this producti0n. IL-6 and CM+LPS in-hibited the production of albumin mRNA,while the expression of AT and AGP 0ccurred 0nly with CM+LPS+Dex. However,IL-6 alone had an inhibitory effect 0n albumin and transferrin mRNA producti0n.Dex maximized the effects 0f lL-6 and CM, and was essential f0r AGP gene expression. C0nclusion: (l)LPS-treated human DF can secrete IL-6, but not IL-101 (2)DF may als0 pr0duce other cyt0kines whichmodulate hepatic pr0tein synthesis during the acute phase response l (3) Dex inhibits IL-6 production byDF, but enhances its ability to stimulate the acute phase response.

In recent years, with being gradually developed, three-dimensional (3D) reconstruction based on pathology and medical imaging technology has shown certain value in the diagnosis and treatment of breast cancer. And with its advantages of providing the spatial location, morphological structure and 3D structure relationships with the surrounding tissues and organs, 3D reconstruction technology has played a key role in the early diagnosis, surgical treatment, and accurate evaluation of the treatment effect after surgery of breast cancer. Although the application of 3D reconstruction technology based on pathology and medical imaging is still inadequate, with the continuous development of science and technology, 3D reconstruction technology will play an increasingly important role in the diagnosis, personalized treatment and prognosis assessment of breast cancer.

Objective To establish a off-pump leukocyte depletion method in canines.Methods Twenty-one healthy adult mongrel dogs of both sexes, weighing 10-12 kg, were randomized into 2 groups: control group (group C, n = 9) and leukocyte depletion group (group LD, n = 12) . An extracorporeal leukocyte filtration end was constructed by aseptic puncture of the bilateral external jugular veins via a blood transfusion line and the leukocyte filter for extracorporeal leukocyte depletion. In group LD, blood was filtered with a MP-300 blood line and a SQ40S leucocyte depletion filter one end placed in the right external jugular vein (artery end) and the other end placed in the left external jugular vein (venous end). After heparin anticoagulation, a MP-300 blood line pump was used as the power. Blood was filtered at a rate of 75 ml/min and it was maintained for 60 min. The artery end was then closed, normal saline injected into the closed circuit, the remaining blood pumped into the body, and then the venous end closed. In group C, aseptic puncture of the bilateral external jugular veins was performed. Arterial blood samples were taken immediately before leukodepletion (baseline, T_0 ) , at 10, 20, 30, 40, 50 and 60 min of leukodepletion (T_(1-6) , depletion period), and at 10, 20, 30, 40, 50, 60, 120, 180 and 270 min after leukodepletion (T_(7-15) , recovery period) for determination of blood routine. MAP, HR, RBC.Plt and body temperature were recorded at T_0 , T_6 , T_(12) and T_(15) . Results There were no significant difference in MAP and RBC between the two groups ( P > 0.05 ) . HR, body temperature, and Plt were significantly lower in group LD than in group C (P < 0.05) .The leukocyte concentration was lower during depletion period in group LD than in group C ( P < 0.05) , while there was no significant difference in leukocyte concentration during recovery period between the two groups (P > 0.05 ). Conclusion The off-pump leukocyte depletion method is successfully established and has exact efficacy with less adverse effects in this study.
