Objective To investigate the function of TRAIUCaspase-3 and NF-κB among the occurrence, development and malignant invasion of bile duct carcinoma. Methods The in-situ hybrization technique and immunochemistry method were adopted to detect expression of TRAIL, Caspase-3 and NF-κB. Results The positive rates of TRAIL expression in carcinoma of bile duct and paracancer tissue were 45.2 % (19/42) and 53.3 %(8/15), respectively. The differences were not significant (P >0.05), and there were no evident difference between expression of TRAIL and every clinic pathology factor(P >0.05). The positive rates of Caspase-3 expression in carcinoma of bile duct were 30.9 %(13/42), which were obviously lower than those in paracancer tissue, 60.0 %(9/15)(P<0.05). However, The positive rates of NF-κB expression in carcinoma of bile duct were 61.9 %(26/42), obviously higher than those in paracancer tissue, 26.7 %(4/15)(P <0.05). The positive rates of Caspase-3, NF-κB expression were relation to metastasis and proliferation, differentiation degree of tissue and survival time (P <0.05), but were independent of sex, ages and position of carcinoma(P > 0.05). Moreover, TRAIL and Caspase-3 manifested positive relationship (P <0.05). On the contrary , NF-κB and Caspase-3 manifested negative relationship (P <0.05). However, there was no relationship between TRAIL and NF-κB(P >0.05). Conclusion Expression of TRAIL has no selectivity of tumour, Its expression is higher or lower which couldn' t absolutely decide tumour' s metastasis and proliferation, and could not decide malignant degree and prognosis of tumour, too. Activation of NF-κB and losing action or absence of Caspase-3 possibly accelerate metastasis and proliferation of tumour, which result in bad prognosis. NF-κB interdicte TRAIL inducing apoptosis approach via control activation of NF-κB, which induce tissue to avoiding apoptosis and multiplication unboundedly, leading to tumour's occurrence, development, metastasis and diffuseness.

Objective To investigate the relationship among Survivin, PTEN and the occurrence, development, soakage and prog-nesis of gastric cancer. Methods The in-situ hybrization technique, immunochemistry and TUNEL method were used to detect the expres-sion of survivin mRNA, PTEN protein and apoptotic cell. Results The positive rate of survivin expression in gastric cancer was obvious higher than that in para-cancer tissue(P <0.01). Moreover, survivin expression rate in advanced clinical stage and low differentiation gastric cancer degree.was higher, compared with para-cancer tissue (P <0.01, P <0.05). The positive rate of PTEN expression in gas-tric cancer was obvious lower than that in pars-cancer tissue (P <0.01). The positive rate of PTEN expression in advanced clinical stage and low differentiation degree of tissue in gastric cancer was lower (P < 0.01). Furthermore, survivin and apoptesis indexes manifested negative relationship in gastric cancer(r =-0.861, P < 0.01), While PTEN and apoptosis indexes manifested positive relationship (r = 0.832, P < 0.01). Conclusions Survivin could be used as a novel marker to detect gastric cancer. PTEN gene lost function, which maybe promote the origin, growth, soakage and metastasis of gastric cancer.

Objective To investigate the effect of the inhalation of nitrous oxide premixed with oxygen (50%∶50%) for analgesia labor on maternal and fetus. Methods A total of 100 cases of pregnant women were provided with nitrous oxide premixed with oxygen (50%∶50%) (control group); Another 100 cases were provided only with oxygen (comparison group). Recording duration of the Labor, way of delivery, bleeding volume, Apgars score, blood gas analysis to maternal radius artery and fetal umbilical blood among all patients. Results The effect for analgesia labor of the premixed gas was much better than that of control group, but there were no significant differences in time of labor, bleeding volume, Apgars score between the two groups. Conclusions The inhalation of nitrous oxide premixed with oxygen (50%∶50%) for analgesia labor benefits pregnant women because of keeping them being a good mental and physical condition. The inhalation of nitrous oxide for analgesia labor is a safe, effective and easy method.

Objective To investigate the effect of pretreatment with parecoxib for postoperative analgesia in patients undergoing laparoscopic hernia repair. Methods Sixty patients undergoing laparoscopic hernia repair were assigned in two groups by random digits table with 30 cases each. The patients in pretreating group received parecoxib 40 mg intravenously before anesthesia, and in control group with the same capacity of normal saline. All patients were anesthetized with combined spinal epidural blockage and tranquilized with pethidine, droperidol and diazepam. Postoperative pain of the abdomen incision was assessed by visual analogue scale (VAS) and the pain of shoulder or back was judged by a 4 grade scale. Side-effects, supplement analgesic, passage of gas by anus 24 h after surgery were observed as well. Results The abdomen incision VAS at 4,8,12,24 h after surgery in pretreating group were lower than those in control group (P ＜ 0.05). And the incidence of pain of shoulder or back was lower in pretreating group (13.3% ,4/30) than that in control group (33.3% ,10/30)(P ＜0.05). While the cases needing supplement analgesic also decreased in pretreating group (13.3% ,4/30) compared with control group (40.0%, 12/30)(P ＜ 0.05). And the side effects and passage of gas by anus 24 h after surgery had no significant difference in two groups. Conclusion Pretreatment with parecoxib in patients undergoing laparoscopic hernia repair may relieve the postoperative incision pain and the pain of shoulder or back while reducing the analgesic supplement without side effects.

OBJECTIVETo study the relationship between allergic rhinitis and fractional exhaled nitric oxide (FeNO).METHODS FeNO was measured in 66 allergic rhinitis patients before and after treatment. Visual analogue scale (VAS) score was used to describe the patient's symptoms. RESULTSFeNO and VAS score were significantly decreased after treatment (t=4.25,P=0.0000;t=3.34, P=0.0008), and the decrease proportion were (14.56±27.23)% and (8.68±53.17)% respectively. Correlation analysis showed FeNO and VAS score was significantly correlated before (r=0.43,P=0.0003) and after (r=0.45,P=0.0002) treatment. After treatment, the decreased proportion of FeNO and VAS score were significantly correlated (r=0.25,P=0.0437). CONCLUSIONFeNO can provide objective evidence for the treatment efficacy of allergic rhinitis.

Objective To explore the epidemiology, clinical and pathological characteristics,treatment and prognosis of Richter's syndrome (RS). Methods The clinical and laboratory feature,treatment, prognosis of two cases were reported, and the related literature was reviewed. Results The major symptom of two cases suffered with enlarged lymph nodes, and pathological examination indicated a diffuse large B cell lymphoma. A large number of mature small lymphocytes were found in peripheral blood and bone marrow, and the immune phenotype was consistent with chronic lymphocytic leukemia. CHOP regiment was used on two cases. One obtained complete remission, and the other cases partial remission. Conclusion RS may occur at early stage after CLL diagnosis. In some cases, the diagnosis of RS and CLL are concomitant.Prognosis of some patients of RS is unfavourable. It was important to take biopsy at early stage.

Objective To investigate the efficacy and adverse events of BACOD regimen for relapsed and refractory non-Hodgkin lymphoma (NHL). Methods Sixty patients with relapsed and refractory NHL received chemotherapy of BACOD regimen: bleomycin 10 mg/m2, intravenous drip on the 2nd and 9th day;cyclophosphamide 750 mg/m2, intravenous drip on 1st day; vindesine 3 mg/m2, intravenous drip on 1st and 8th day; cytarabine 150 mg/m2, intravenous drip on 2nd-5th days; dexamethasone 10 mg/m2, intravenous drip on 2nd-5th days; every 3 weeks was one cycle. Results Eighteen cases (27.7 %) received the complete remission (CR), 30 the partial remission (PR), 13 stable disease (SD) and 4 progressive disease (PD). The overall response (CR+PR) rate was 70.8 %. The median remission time of patients with response was 11 months(2-38 months). The 1-year survival rate was 32.3 % and the 2-year survival rate was 24.6 %. The main adverse events were myelosuppression. Conclusion BACOD regimen can be used as the relief regimen of relapsed and refractory NHL.

Objective To investigate the epidemiology of patients in malignant hematologic neoplasms with fungemia and provide evidence for clinical therapy. Methods 23 cases of patients of malignant hematologic neoplasms with fungemia concurrent clinical material, the dangerous factor, the fungus colony classification as well as the treatment and the prognosis were carried on the review analysis. Results Each patient with fungemia was seriously ill with two or more predisposing factors;Candida ablicans accounted for 47%;the rate of candida parapsilosi, candida tropicalis were 17%, 12%. In the 23 cases of patients,13 cases of patients cure (56.5%), 8 cases of patients died (34.7%);2 cases of patients give up (8.6%). Conclusion Fungemia in the patients of malignant hematologic neoplasms usually occurred with predisposing factors. Important measures to reduce mortality include curing the underlying diseases, emphasis on mornitoring fungal pathogen and susceptibility tests, early diagnosis and compliance medication principles.

Objective To investigate the significance of serum interleukin-1β,interleukin-2,interleukin-6,TNF-α,erythrocyte sedimentation rate(ESR),c-reactive protein(CRP),IgA,IgG and IgM in patients with ankylosing spondylitis(AS),and to analyze their relationship with the Bath ankylosing spondylitis disease activity index (BASDAI). Methods Participants of this study included 45 AS patients(patient group)and 30 healthy subjects (control group).The patient group was further divided into an active subgroup and an inactive subgroup based on the disease activity assessed by using BASDAI.Then serum levels of IL-1β,IL-2,IL-6,TNF-α,ESR,CRP,IgA,IgC and IgM were tested in all the subjects,and the values were compared between different groups.In addition,the relationship between various parameters and those with BASDAI were also evaluated. Results The serum levels of ESR,CRP,IgA,lgM,IgG,IL-1β,IL-2,IL-6 and TNF-α in patients with AS were significantly higher than those in the healthy controls(P<0.05).The serum level of CRP,IL-2 and IL-6 were significantly different between the active and inactive subgroups(P<0.05).There was a positive correlation between CRP and IL-6,IL-6 and IL-2,as well as IgA and IgG levels.The IL-2,IL-6 and CRP levels were positive correlated with BASDAI.Conclusion It was suggested that the serum levels of IL-2,IL-6 and CRP can be used to assess the disease activity in patients with AS.
