Inflammatory bowel disease (IBD) is a group of chronic and non-specific intestinal inflammatory diseases of undetermined origin,which including ulcerative colitis (UC) and crohn's disease (CD).Interleukin(IL) is a kind of cytokines,and plays an vital role in growth,differentiation,immune response of immune cell.With a intensive study in the pathogenesis of IBD in the world,parts of IL were found and confirmed to be a important role in the progression of IBD,and will become a new hot spot in the research of the diagnosis and treatment of IBD.

The early clinical symptoms of newborns with acute bilirubin encephalopathy are absent or slight.In addition ,this diseaes is no specificity.So ne wborns with acute bil rubin encephalopaht y is easy to miss ni d iagnosis.If the best treatmetn opportunity of this disease is delayed,it can affect the long-term prog-nosis and survival.Neuros-pecfi ic nlo ase,cranial magnetic resonance imga ing,electroencpe halogram,amlp i-tude integrated electroencephalogram and rb ainstem auditory evoked potential can judge the position and in-tensity of brain injury from the different angle and level,which can provide important basis for the early diag-nosis and intervention of acute bilirubin encephalopathy.

Objective To investigate the clinical features,treatment and prognosis of paraneoplastic pemphigus (PNP).Methods A retrospective study was performed on 11 patients with PNP hospitalized in the Department of Dermatology,Ruijin Hospital.Clinical characteristics of these patients were analyzed.Results Of the 11 patients,10 had oral or labial erosions or ulcers,and 6 had obstructive bronchiolitis.Computed tomography (CT)showed solitary internal tumors in all the patients after appearance of skin lesions,and 8 of them were diagnosed with Castleman's disease.All the patients had been treated with corticosteroids before operation,but achieved no obvious improvement.After 2-7 months of postoperative treatment with low-dose prednisone and thalidomide,both cutaneous and mucosal lesions healed with the relief of pulmonary symptoms in 5 patients.Conclusions Oral erosions or ulcers appear to be the most common initial manifestation of PNP with Castleman's disease as the most frequent accompanying tumor.Early detection and timely resection of tumors are keys to successful treatment of PNP,and postoperative treatment with glucocorticoids and thalidomide proves to be effective for PNP.

Objective To research the clinical evaluation of potassium dehydroandrograpolide succinate injection in the treatment of COPD combined with CAP and its influence on plasma IL-33, PCT and hs-CRP levels.Method 91 patients with COPD combined with CAP in our hospital from April 2015 to August 2016 were selected and divided into the observation group (48 cases) and the control group (43 cases).The control group was given routine treatment, the observation group was given on the basis of the above treatment of potassium dehydroandrograpolide succinate injection.The clinical efficacy and plasma IL-33, PCT and hs-CRP levels were compared between the two groups after treatment.Results Before treatment, the IL-33, PCT, hs-CRP of two groups of patients had no significant difference.After treatment, the total effective rate of the observation group was 91.67% higher than that of the control group 74.42%, the difference was statistically significant (P<0.05).All the clinical symptoms time of the observation group was significantly lower than that of the control group, and the clearance rate of the observation group (85.42%) was significantly higher than that of the control group (67.44%), the difference was statistically significant (P<0.05), the indexes of the two groups of patients were decreased, the indexes of the observation group significantly lower than that in control group, the difference was statistically significant (P<0.05).There was no significant difference in the incidence of adverse reactions between the observation group and the control group .Conclusion Potassium dehydroandrograpolide succinate injection can significantly improve their plasma IL-33, PCT and hs-CRP levels, the respiratory pathogen and inflammatory mediators are effectively removed, and has good clinical effect, and no serious adverse reactions during treatment.

Objective To study the mechanism of senile escaping of benign prostatic hyperplasia(BPH) condition. Methods With polymerase chain reaction based telomeric repeat amplification protocol assay(TRAP),telomerase activity was examined in 13 normal prostate tissues,35 benign prostatic hyperplasia tissues,33 hyperplastic tubercle and diaphragm. Results Telomerase activity was detected in 2 of 13(15%)normal prostate tissues,17 of 35(49%)benign hyperplasia tissues,14 of 33(42%)hyperplastic tubercle tissues and 1 of 33(3%)diaphragm tissues.The positive rate of telomerase in BPH is higher than normal prostate (P

Objective To study the effects of diacylglycerol(DG)on body weight of rats and its possible metabolic mechanism. Method (1) SD rats (n=30) were randomly divided into 3 groups. They were given free access to diets containing 7% (wt) triacylglycerol (TG, control group), 20% (wt) TG or 20% (wt) DG diets, respectively for 8 w. The changes of body weight, height, food intake, and feces were recorded. At the end of experiment, abdominal fat weight (including perirenal fat and epididymal fat), blood lipids were detected. (2) 13 w male Wistar rats (n=50) were divided into 2 groups(administrated with 10% TG or DG emulsion, respectively)in postprandial blood fat profile experiment. Blood lipids of 5 rats were analyzed at desired interval. (3) 6 w male Wistar rats (n=30) were randomly divided into 3 group, control group, DG group and TG group, administrated with glucose solution, 20%DG emulsion and 20%TG emulsion respectively for 6 d. Urine in 144 hr was collected continuously and analyzed for total ketone bodies. Results High DG diet resulted in a significant reduction in both body weight gain, ratio of abdominal fat to body weight and serum TG levels compared with the high TG diet. DG group have higher FFA level in portal vein and lower TG level in jugular vein than those of high TG group. But urine ketone body level of high DG group was higher than high TG group. Conclusion Dietary DG reduced fat accumulation inabdominal region, body and blood, and these effects may be involved with different metabolic ways of DG compared with TG.

Objective Effects of intra articular injection of 153 Sm citrate HA on antigen induced arthritis were investigated to provide the theoretical fundation for its clinical application.Methods Rabbit arthritis was induced by subcutaneous injection of ovalbumin at weeks 2 and 4,and by intra articular injection of it at week 6.The dosage of 1 85?10 7 Bq or 3 7?10 7 Bq of 153 Sm citrate HA was injected separately into a side of knee joint.The severity of arthritis was determined by joint swelling,skin surface temperature,macroscopic and histologic changes in joints when the rabbits were killed at week 9 after establishment of model.Results Both dosages of 153 Sm have an initial pro inflammatory effects during one week after injection,and then resulted in reduction of joint diameter and skin surface temperature. 153 Sm (3 7?10 7 Bq) showed a more alleviation than 153 Sm (1 85?10 7 Bq) in respect of macroscopic and histologic changes.Conclusion Synovectomy with 153 Sm citrate HA is effective for treatment of chronic arthritis with dependence on the doses and deserves further study.

Objective To study the relationship between endothel in-1 in plasma and TCD in patients with brain injury.Methods We measured dynamically the level of ET-1 in plasma on 33 adult brain injured patients. Cerebral vasospasm was detected by transcranal Doppler sonography (TCD).Results 1.During 6-8 days, 13-15 days after injury,there was a significantly positive correlation between the level of ET-1 in plasma and cerebral vasospasm (r=0.533,P=0.002;r=0.423,P=0.02),especially during 6-8 days after injury. The increase of the level of ET-1 in plasma paralleled paroled with the time of cerebral vasospasm developed. 2.During 6-8 days after injury, the level of ET-1 in plasma of patients with cerebral vasospasm was obviously higher than those without cerebral vasospasm obviously (P
