Objective To study the characteristics of the inpatients with cancer pain, the application of WHO three steps analgesic solution (three steps analgesic) and the application of traditional Chinese analgesic (TCM). Methods Retrospective investigation of distribution of cancer pain, situation of pain, application of TCM, and the application of conbination of three steps analgesic and TCM treatment, by using, clinical data from the oncology department of afflicated hospital of Liaoning university of TCM ranging from May, 2009 to June, 2010. Results 47.4% (517/1 090) of patiens were combined with cancer pain. Among the patients, majority were the middle-aged and old (59.19%) and male patients (57.63%). The abdominal pain (57.45%) and chest pain (37.91%) were topranks, and the distributions of pain period such assustainability (65.37%), moderately (53.38%), bloated pain (49.71%) and dull pain (29.98%) had larger proportion. The TCM excessive patterns(50.87%) were more than the TCM deficiency patterns (28.63%) or mixed TCM patters of excessive and deficiency patterns (20.50%). A total of 46 patients had mild pain, 76.09% of whom used TCM, 15.22% used first step drugs, and 8.69% used combination treatment, while 276 patients with moderate pain used second step analgesic, and 91.67%of them also used TCM, the rest195 patients with severe pain used third step analgesic, and 55.38%of them also used TCM. The time of pain release of TCM alone or combination of TCM and three steps analgesic were longer than the three steps analgesic alone. Conclusions Early intervention of traditional Chinese medicine on the patients with mild pain could reduce the dose of first step analgesic drugs, and TCM application at the second step could delay the speed of transtformfrom second to third step pain, and TCM could prevent the side effects of morphine when patients were with severe pain.

Objective To investigate the association between the polymorphisms of brain-derived neurotrophic factor(BDNF) gene C270T and sporadic Alzheimer's disease(SAD) in Han Chinese.Methods The polymerase chain reaction-restriction fragment length polymorphism(PCR-RELP) was used to detect BDNF gene C270T genotype and allele frequencies in 55 SAD patients and 80 age-and sex-matched healthy people(as normal control group).Results The frequencies distribution of BDNF gene C270T genotype and allele in the normal control group were suit to Hardy-Weinberg equilibrium(?2=0.167,P=0.682).The frequencies distribution of genotype and allele in the SAD group[C/C:52(94.5%),C/T:3(5.5%) and C:97.27%,T:2.73%]and normal control group[C/C:74(92.5%),C/T:6(7.5%) and C:96.25%,T:3.75%] were no statistical differences.Conclusion There is no association between the polymorphisms of BDNF gene C270T and SAD in Han Chinese.

Background:Secondary lymphoid tissue chemokine( SLC)is involved in lymphoid homing and anti-tumor immune response,and has a chemotactic effect on intestinal lymphocytes. Several animal studies have shown that SLC is involved in the occurrence and development of ulcerative colitis( UC). Aims:To investigate the expression and significance of SLC in UC. Methods:Forty active UC patients from Dec. 2010 to Dec. 2012 at Affiliated Hospital of Nantong University were enrolled,and 20 healthy volunteers were served as controls. Expression of SLC in the colon mucosa was detected by immunohistochemistry,and its relationship with severity of UC was analyzed. Results:SLC was positively expressed in all UC patients,while was negatively or weakly positively expressed in controls. Expression of SLC in UC patients was significantly higher than that in controls(4. 16 ± 0. 78 vs. 0. 52 ± 0. 11,P<0. 05). Expression of SLC was correlated with the severity of involvement of UC. Conclusions:Expression of SLC participates in development and progress of UC. SLC may play an important role in the induction of local damage and pathological changes of UC.

Objective To compare the differences between endoscopic resection and laparoscopy?assisted surgery or transanal endoscopic resection for rectal neuroendocrinal tumor. Methods Clinical data of patients who underwent endoscopic or surgical resection of neuroendocrinal tumor of less than 2 cm which were confirmed by pathology from December 2010 to November 2013 were retrospectively analyzed. Results Twenty cases of endoscopic treatment, including 17 cases of ESD, 3 cases of EMR,were included in endoscopy group;while 18 cases treated with surgery were included in surgery group, among which 12 ca?ses underwent transanal endoscopic microsurgery and 6 cases laparoscopic resection. The mean lesion sizes were 7 mm(4?18 mm)and 8 mm(3?15 mm),respectively. Pathology showed there were 16 cases of grade G1 neurocrinal tumor and 2 G2 cases in surgical group. There was no lymphvascular invasion with clear margin in the endoscopy group,but three cases of lymphvascular invasion in surgical group. No treatment?related se?vere adverse event occurred in either group. The time for oral food intake was 2?0 d(1?4 d) in endoscopy group, while that in surgery group was 2?4 d(1?7 d)(P=0?295). The hospital stay was(6?80±2?12) d in endoscopy group and(8?59±2?85)d in surgery group, respectively(P=0?034). And the total hospitalization cost was 10 488(4 128?15 296) yuan and 15 590(3 024?40 503) yuan(P=0?031) in the two groups, re?spectively. The follow?up was 25 months(2?48 months)and no recurrence was found. Conclusion Endo?scopic resection, especially ESD, is a new approach to treat colorectal neuroendocrinal tumor,advantageous over surgery in shorter hospitalization time, minimal invasiveness, faster postoperative recovery, less compli? cation, and reduced hospitalization cost.

AIM:To investigate the maturation of mice immature myeloid dendritic cells (mDCs) induced by antigen(Ag)85B of mycobacterium tuberculosis, and the expression of TSLPR and OX40L mediated by TSLP in vitro. METHODS:Recombinant mouse GM-CSF ( rmGM-CSF) and rmIL-4 were used to induce bone marrow precursor cells of C57BL/6 mice to differentiate into immature mDCs in vitro.mDCs were identified followed by purification using CD 11c binding magnetic beads .The morphological characteristic of mDCs was observed under inverted phase-contrast microscope and scanning electron microscope .The surface phenotypes of mDCs were determined by flow cytometry .To obtain the opti-mal concentrations of Ag85B and TSLP, immature mDCs were cultured with different concentrations of Ag 85B or TSLP at 0 (control group), 50, 100 and 200 μg/L for 24 h, and the expression of cell surface molecules CD 80, CD86, TSLPR and OX40L was detected by flow cytometry.In addition, the expression of TSLPR and OX40L in Ag85B and TSLP-co-stimula-ted mDCs was determined by flow cytometry .RESULTS:After 7 d of culture in vitro, the cells showed irregular dendritic protrusions under the inverted-phase contrast microscope , and had wrinkles and dendritic splits under scanning electron mi-croscope , conformed to the morphological characteristics of immature mDCs .The mDCs cells expressed higher level of spe-cific marker CD11c, lower level of co-stimulatory molecules CD80 and CD86, which conformed to the phenotype of imma-ture mDCs.The CD80 +and CD86 +cell ratios of mDCs displayed significant increases in 50, 100 and 200μg/L Ag85B or TSLP groups compared with control group (P<0.05).The ratios of TSLPR +and OX40L+cells did not differ among dif-ferent concentrations of Ag 85B groups.The ratios of TSLPR +and OX40L+cells were significantly increased in 100 μg/L and 200μg/L TSLP groups compared with control group and 50μg/L TSLP group (P<0.05).Under the circumstance of optimal Ag85B or TSLP treatment concentration at 200 μg/L, there was significantly decreased in TSLPR and OX 40L cell ratio of mDCs in Ag85B group or Ag85B combined with TSLP group when compared with TSLP group (P<0.05), and no significant difference among Ag85B group, Ag85B combined with TSLP group and control group was observed .CONCLU-SION: Ag85B enhances mDCs maturation by up-regulating the expression of co-stimulatory molecules CD80 and CD86, and inhibit the expression of pro-inflammatory specific molecules TSLPR and OX40L on TSLP-activated mDCs, indicating that Ag85B modifies the development of asthmatic airway inflammation through the pathway of TSLP -activated mDCs.

Objective To investigate the activation of nuclear factor-B (NF-B)and hypoxia-inducible factor-1 (HIF-1)in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Subjects were classified into mild-to-moderate OSHAS group (n = 16), severe OSAHS group (n = 14) and the matched control group (n=30). Gene and protein expressions of NF-B and HIF-1 were measured by RT-PCR, Western blot in peripheral blood mononuclear cells (PBMC). Results NF-κB p65 mRNA and NF-κB p65 protein,HIF-1α mRNA and HIF-1α protein in PBMC were significantly higher in severe OSAHS group than those in mild–to-moderate group and control group (P<0.01). But there were no significant difference in NF-κB p65 mRNA and NF-κB p65 protein between mild-to-moderate group and control group (P=0.068, P=0.254 respectively). Only gene (P<0.05) not the protein (P=0.777) of HIF-1αwas higher in mild-to-moderate as compared with control group. Both NF-κB p65 mRNA and HIF-1αmRNA were positively correlated with AHI (r=0.493, P=0.006, r=0.508, P=0.004), while negatively correlated with nighttime lowest blood oxygen saturation (LSaO2)(r=-0.488, P=0.006, r=-0.46, P=0.011). There was a positive correlation between NF-κB p65 protein level and AHI (r=0.669, P<0.001). HIF-1αprotein level was positively correlated with AHI, ODI (r=0.628, P=0.001;r=0.480, P=0.018). There were positive correlations between NF-κBp65mRNA and HIF-1αmRNA (r=0.543, P=0.002), NF-κBp65 and HIF-1αprotein respectively (r=0.716, P<0.001). Conclusions As the gene and protein of NF-κB and HIF-1 were up-regulated in patients with OSAHS, and also positively correlated with the severity of sickness. We conclude that both NF-κB and HIF-1 were involed in the pathogenesis of OSAHS.

Objective An ideal small bowel transplantation model is the prerequisite and guarantee of small bowel transplan-tation-related researches.The aim of this study is to establish a pig model of orthotopic segmental small bowel transplantation by modifi-cation of blood vessel reconstruction and surgical techniques. Methods Twenty healthy pigs were equally assigned as donors and re-cipients.The superior mesenteric vessels were freed and the distal ileum harvested as grafts.After irrigation and preservation, the small bowel was transplanted by end-to-end anastomosis of the superior mesenteric arteries and veins, and then the small bowel was re-constructed simultaneously to restore intestinal continuity, with the proximal part of the graft brought out as a stoma for the purpose of graft monitoring. Results Transplantation was successfully performed in 9 of the 10 cases, with a success rate of 90%.The donor operations averaged 100 min, recipient operations 172 min, warm ischemia 1.3 min, cold ischemia 96 min, and vascular anastomosis 27.6 min.No postoperative anastomosis fistula occurred in any of the cases. Conclusion The pig model of orthotopic segmental small bowel transplantation is ideal for small bowel transplantation-related researches.

Objective To investigate the effects of glucagon-like peptide-1 (GLP-1) on liver oxidative stress, TNF-αand TGF-β1 in rats with diet-induced non-alcoholic fatty liver disease (NAFLD). Methods Thirty male rats were randomly divided into 3 equal groups and fed for 16 weeks with normal diet (ND), high-fat diet (HFD), or high-fat diet with intraperitoneal injection of liraglutide (GLP-1, administered in the later 4 weeks). The rats were then sacrificed to obtain blood samples and liver tissues for analyzing the levels of blood aminotransferase (ALT), triglyceride (TG), and total-cholesterol (TC) using an automatic biochemical analyzer and the levels of superoxide dismutase (SOD), malondial-dehyde (MAD), free fatty acid (FFAs), TNF-αin the liver homogenates and TGF-β1 in serum by radioimmunoassay or ELISA. Results Compared with ND group, HFD group showed significantly increased body weight, liver index, serum levels of ALT, TG, TC, and TGF-β1, and TG, TC, MAD, FFAs, and TNF-a in the liver homogenates, with also significantly increased degree of hepatic steatosis and inflammation activity (P<0.05) and lowered level of SOD. All these changes were markedly ameliorated in GLP-1 group (P<0.05). Conclusion Liraglutide can reduce high-fat diet-induced hepatic steatosis, improve oxidative stress and lipid peroxidation, and decrease TGF-β1 and TNF-a levels in serum and liver homogenates, suggesting its potential as a therapeutic agent for NAFLD.
