Cytokines involve in many diseases. It' s reported that reduction or increase of cytokines is an important factor to lead to immunological diseases in nervous system. Other studies have found that certain cytokines in the different stages of the same disease play a different role. Understanding the specific mechanisms of cytokines in autoimmune diseases of the nervous system is necessary for providing theoretical basis of new ways to treat these diseases. This article will review the progress of some main cytokines in nervous systemic immunological diseases.

The incidence of carotid stenosis disease increases with age,and it is one of the major causes of ischemic stroke.In recent years,with the rapid development of endovascular treatment technology,the therapeutic means,including carotid angioplasty and stenting,has been widely carried out both at home and abroad.This article reviews the advances in endovascular treatment of carotid stenosis.

Objective To introduce the recent studies about the lymph node-targeted chemotherapy for gastric carcinoma. Methods The literatures on the lymph node-targeted chemotherapy for gastric carcinoma in recent years were collected and reviewed. Results The lymph node-targeted chemotherapy for gastric carcinoma was effective because it couled improve the drug concentrations in regional lymph node. Conclusion As a part of multiple treatments for gastric carcinoma, lymph node-targeted chemotherapy will be further developed.

Objective To establish the animal model of damp-heat syndrome(DHS) and explore the expression of aquaporin(AQP) 3,4 gene in gastric mucosa.Methods Thirty SD rats were randomized into 3 groups and observed for 20 days.Group A(normal group,NG) was fed with routine method.Group B(Pi deficiency syndrome group,PDS) was fed alternatively with routine method and aqua of cassia angustifolia Vahl.Group C(DHS) was fed with fat,honey liquid and treated with damp-heat environment.The expression of AQP 3,4 gene in the 3 groups were determined by fluorescence quantitative polymerase chain reaction(FQ-PCR).Results The symptoms and signs in Group C were simiar to the clinical DHS.Expression of AQP3 gene in DHS was statistically significant higher than that in PDS and NG(P

Objective To investigate the inhibitory effect of cyclooxygenase-2 (COX-2) inhibitor celecoxib alone and in combination with somatostatin (SST) analog octreotide on human gastric cancer. Methods Fifty one gastric cancer patients were randomly divided into 3 groups. The patients in control group(n=15)took no medicine before gastric cancer resection. Celecoxib group(n=18)patients took celecoxib orally 0.2 g/d for 7 days before surgery. Combination group(n=18) patients took celecoxib orally 0.2 g/d and were injected octreotide 100 ?g/d subcutaneously for 7 days before surgery. The resected specimens were examined histologically, including status of tumor necrosis, inflammatory cells infiltration and fibrous tissue proliferation. The microvessel density (MVD) and the expression of COX-2 in gastric cancer were evaluated by immunohistochemical methods. The apoptosis of tumor cells was measured by terminal deoxynucleotidyl transferse-mediated-dUTP nick end labeling. The expression of somatostatin receptor (SSTR) -1,SSTR-2 and SSTR-3 mRNA in gastric cancer tissue obtained by biopsy in all patients were detected by using real time fluorescence quantitative RT-PCR. Results Compared with control group, gastric cancer tissue necrosis increased significantly(P

Objective To observe the effect and study intervenient action of Kuijieling Granules (KG) in treating ulcerative colitis (UC) during the active period by the clinical experiment. Methods The patients of active UC (damp-heat syndrome) were randomly divided into 2 groups (KG+SASP group and SASP group) to observe pathological changes of the mucosa,syndrome effect and main symptoms scores,and the protein expression of TLR4,CD14 and NF-?B p65 were detected by immunohistochemistry. Results KG+SASP group had better effect than SASP group in syndrome and mucosa (P0.05). There were outstanding differences among the pathologic grade of UC about IA of TLR4,CD14 and NF-?B p65. The expression of TLR4,CD14 and NF-?B p65 were decreased by treatment (P

Objective:To study the effects of rat interleukin-10 (rIL-10) gene treatment on the expression of collagen , matrix metalloproteinase 13(MMP13) and their specific inhibitors the tissue inhibitor of metalloproteinase 1(TIMP1) in porcine serum in-duced liver fibrosis rats then to explore the anti-fibrotic effect of rL-10.Methods:Thirty SD rats were divided into normal control and fibrosis model group.Normal control group (group C) was intraperitoneally injected with 0.5 ml normal sodium twice a week for 8 week, while the fibrosis model group was injected with equal volume of pig serum for 8 week.At the beginning of the 5th week, fibrosis model group was further randomly divided into a fibrosis model subgroup ( group M ) , rIL-10 gene treatment subgroup ( group I ) and empty vector control subgroup(group P).Rats in group C and M were injected with Ringer’s solution as a reagent control via the tail vein weekly, rats in group I were injected with the rIL-10 plasmid pcDNA3-rIL-10, and rats in group P were injected with empty vector pcDNA3.All rats were sacrificed at the end of 8th week, and the liver tissue samples were collected to observe deposition of collegan in liver tissue by sirius red staining and detected the expression of MMP 13 and TIMP1 in the liver tissue by SP immunohistochemistry .Re-sults:Sirius red staining showed that the area of the collegan deposition was dramatically increased in fibrosis model subgroup and emp -ty vector control subgroup compared with the normal control group , and the area of the collagen deposition was dramatically decreased in rIL-10 gene treatment subgroup compared with the fibrosis model and empty vector control subgroup .Immunohistochemistry analysis showed that the expression of MMP 13 and TIMP1 in fibrosis model subgroup and empty vector control subgroup was significantly higher than the normal control group , but compared with normal control group , expression of MMP13 was significantly increased and expres-sion of TIMP1 was significantly decreased in rIL-10 gene treatment subgroup .Compared with fibrosis model subgroup and empty vector control subgroup, the expression of MMP13 and TIMP1 was dramatically decreased in rIL-10 gene treatment subgroup.Conclusion:rIL-10 gene treatment attenuates the area of collagen deposition in liver fibrosis rats associated with downregulation of TIMP 1.

Objective To observe the effects and mechanism of pretreatment in rats with prostaglandin E1 on liver after hemorrhagic shock and resuscitation(HSR).Method In total,32 male SD rats were randomly(random number)divided into four groups(n=8):group A(sham group),group B(shock group),group C(HSR group)and group D(Lipo-PGEl+HSR).In group B,rats were sacrificed 90 min after shock,and in group C,rats were anesthetized and then subjected to hemorrhagic shock followed by resuscitation.In group D,rats were pretreated with Lipo-PGEI one hour before HSR.Liver function,NO and ET.1 were measured,and pathological changes of liver tissue in each group were observed,and the expres8ions of iNOS and ET.1 of liver tissue were measured by using immunohistochemistry 6 hours after HSR.Data were analyzed by analysis of variance,and P<0.05 was considered as significantly different in statitistics.Results The levels of liver iNOS and ET-I increased in HSR group compared with shock group [(O.225±0.080)vs.(0.082±0.021)and(0.292±0.047)vs.(0.082±0.035),P<0.05].Pretreatment with Lipo-PGEl markedly reduced the damage of Liver function,and lowered the levels of NO and ET-I.which were consistent with decrease in iNOS and ET-16 hours after HSR[(0.116±0.034)vs.(0.225±0.080)and(0.198±0.041)vs.(0.292±0.047),P<0.05].Conclusions Pretreatment with Lipo-PGEl could reduce liver injury after HSR.The mechanisms might be attributed to inhibiting iNOS and ET-1,regulating the balance of NO/ET-I.

Objective To analyze the clinical characteristics of Klebsiella pneumoniae infection in preterm infants. Methods Clinical data of 75 preterm infants infected with Klebsiella pneumoniae treated in BaYi Children's Hospital from February 6,2008 to February 10,2010 were retrospectively analyzed.The difference of auxiliary examination between early-onset and late-onset infection group were compared by two independent samples t test.Spearman correlation analysis and non-conditional Logistic regression analysis were used to analyze the high risk factors and the prognostic factors of Klebsiella pneumoniae infection in preterm infants. Results The incidence of Klebsiella pneumoniae infection was 2.8％ (75/2721) in preterm infants,and the mortality rate was 9.3％ (7/75). There were 71 cases of Klebsiella pneumoniae sepsis and 4 cases of Klebsiella pneumoniae pneumonia.Among 75 cases,63 cases were early-onset infection (onset age≤72 h) and 12 were late-onset infection (onset age＞72 h).All patients presented with poor response,heart rate during quiet sleep ＞ 160/min and low oxygen saturation.The mean corpuscular volume and mean corpuscular hemoglobin concentration in early-onset Klebsiella pneunoniae infection cases were higher than those in late-onset neonates [(128.87±24.60) fl vs (113.72±13.54) fl,t=-2.07,P＜0.05and (38.11±2.15) pg vs (36.98±1.05) pg,t=-2.76,P＜0.05].Low birth weight and caesarean section were associated with early-onset Klebsiella pneumoniae sepsis (r=0.250 and -0.240,P＜0.05). The prognosis of Klebsiella pneumoniae infection was associated with hospital stay and duration of premature rupture of membranes (r=0.368 and 0.318,P＜0.05). Conclusions There were no specific clinical manifestations for Klebsiella pneumoniae infection in preterm infants.Preterm infants with low birth weight,long duration of premature rupture of membranes,delivered by caesarean section and received invasive operation are likely to develop Klebsiella pneumoniae infection.
