Objective To explore the influence of lung IL-10 on interstitial dendritic cells in multiple organ dysfunction syndrome(MODS),and its role in immunological dysfunction.Methods The model of MODS was replicated by injecting zymosan into the peritoneal cavity of C57BL/6 mice.The mice were then randomly divided into normal groups as well as the groups of 3-6 hours,12-48 hours,5-7 days and 10-12 days post trauma.The level of CCR7 mRNA in lung was detected by RT-PCR and the proteins of CCR7 and IL-10 were immunohistochemically stained.The number of mononuclear cells in MHC-II positive peripheral blood was determined by flow cytometry.Results At the early stage of injury(3-6 hours),the number of IL-10 positive cells and the expression of CCR7 increased,but the number of mononuclear cells in MHC-II positive peripheral blood decreased.At the stage of 12-48 hours,the number of IL-10 positive cells and the expression of CCR7 continued to increase obviously,and that of mononuclear cells in MHC-II positive peripheral blood went on decreasing.At the stage of 10-12 days,the number of IL-10 positive cells increased dramatically compared with that in normal group,but the expression of CCR7 declined obviously in contrast to that in 12-48 hours,and the number of mononuclear cells in MHC-II positive peripheral blood decreased to the lowest level.Conclusions The expression of IL-10 in lung could inhibit the excessive immunological damage induced by dendritic cells on the one hand,and it probably leads to immunosuppression by reducing the CCR7 expression of dendritic cells and the number of mononuclear cells in MHC-II positive peripheral blood on the other hand.

Two parental strains BY-14 and BY-6,with high leavening ability in lean and sweet dough respectively,were selected.Through spore production and separation,two haploids with opposition types were selected for cross-breeding.At last one hybridization strain was obtained,with good fermentation ability as BY-14 in lean dough and better than BY-6 by 25%in sweet dough.

Objective The significance of serum cytokine profile in coronary heart disease patients have been evaluated by observing the variation cytokines Methods The serum IL-1 a,IL-1 ?,IL-2,IL-4, IL-6 ,IL-8,IL-10,VEGF,IFN-?,,TNF-?,MCP-1 and EGF in 76 patients and 26 matched healthy volunteers have been observed.Serum cytokines had been measured by protein chips methods in EVIDENCE 180 automatic biochips analyzer and cytokine profile were got by bioinformatics.Results The serum level of IL-1?,IL-6,IL-8,and TNF-? were (4.32?8.14) ng/L ,(13.16?16.81) rig/L,(375.53?292.14) ng/L,(15.46?15.38) ng/L respectively,which increased obviously in patients (P

Objective To explore the role of kidney interstitial dendritic cells in irnmunodissonance moechanism in mice with multiple organ dysfunction syndrome(MODS).Method The model of MODS wasmade by injecting zymosan into the peritoneal caiecty of C57BL/6 miee,and the mice were randomly divided into 5 groups,namely,normal,3～6 hours,12～48 hours,5～7 days,10～12 days after administrating zymosan. Pathological changes of kidney interstitial dendritic cells were observed by transmission electronic microscopes. Specific sudaee markers CD205,CD11e,CDSO,MHCⅡmolecules I-A~b,CD4~+ and CD8~+T lymphocyte subgroups in peripheral blood were detected by immunohistochemistry and flow cytomctry.Results In acute injury stage,in comparison with normal group,interstitial dendritic cells had a continuous proliferation with high expression of CD80 and I-A~b(P

AIM: To discuss the clinical applications of methods to localize nasal cut ends and the effects of Z-plasty in the surgeries for lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption.
METHODS: From September, 2010 to October, 2013, a total of 37 patients ( 37 eyes ) with lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption were operated for anastomosis of lacrimal canaliculi disruption and suture of lower eyelid longitudinal. Different methods to search for the nasal cut ends of lacerated lacrimal canaliculi, such as “under a microscope directly”, “guided by probing needle” and“pigtail curved probe”. Then, to repair lower eyelid longitudinal laceration with Z-plasty transposition flaps. Follow up was 3mo~2a after operation.
RESULTS: All nasal cut ends could be found successfully on 37 patients;Lacrimal duct unobstructed in 31 patients (83. 8%), improved in 5 patients (13. 5%), invalid in 1 patient (2. 7%),the overall successful rate was 97. 3%; the eyelids repair was satisfactory, small scars, the appearance and function was normal.
CONCLUSION: The nasal cut ends can be found successfully by “directly under a microscope”, “guided by probing needle” and“pigtail curved probe”;the effect of silicone drainage tube used as lacrimal canaliculi bracket is satisfactory; most patients gained excellent recovery for both appearance and function after Z-plasty.

Objective To investigate clinical significance of computed tomography (CT) scan in diagnosis of bronchial foreign body in children.Methods Twenty-one suspected children with bronchial foreign body were studied with spiral CT cross-section scan and coronal reconstruction and diagnosis was confirmed with bronchoscopy.Results The foreign body was displayed in all of 21 cases. CT scan showed foreign body was located in right main bronchial 12 cases, right middle bronchial 1 case, right inferior lobar bronchial 2 cases and left main bronchial 6 cases. Foreign bodies were extracted with bronchoscopy.Conclusion CT scan can display and locate accurately foreign body in bronchial of children,and has very important diagnostic value in patients having atypical histories, clinical and radiological findings.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.

METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.

RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).

CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.

Objective To evaluate the differentiation-inducing effect of phenylacetate on pancreatic carcinoma cells and underlying mechanism of RNA editing deaminase in cell proliferation and differentiation. Methods The effect of phenylacetate on cell proliferation and cell cycle were investigated in cultured pancreatic carcinoma BXPC-3 cell lines by methylthiazoletetrazolium( MTT) assay, and flow cytometry. The effect of phenylacetate on the expression of RNA editing deaminase (ADAR2 mRNA) in BXPC-3 cells and fresh pancreatic carcinoma specimen was evaluated by RT-PCR. Results ADAR1 mRNA expression was positive in human pancreatic carcinoma tissues and BXPC-3 cell lines. After application of 1.0 and 2.0 mmol/L phenylacetate for 24 h and 72 h, BXPC-3 cell growth inhibition rate increased, G0/G1 phase cells decreased, S phase cells increased, ADAR2 mRNA expression decreased ( P < 0.01 ). Conclusion ADAR2 mRNA played a vital role of regulation in the process of pancreatic carcinoma cells growth and differentiation. Phenylacetate could regulate the proliferation and differentiation of pancreatic carcinoma cells through the regulation of ADAR2 mRNA expression.
