OBJECTIVETo investigate effects of the variation of immune function in high humidity environment in different time, and lay a foundation for further study of the related mechanism.

METHODThirty SD rats were divided into 3 groups (n = 10): 20 day group, 40 day group in 90% relative humidity chamber and control group in normal relative humidity. Peripheral blood and spleens were collected to detect the levels of T lymphocyte subsets by Flow Cytometery.

RESULTSIn peripheral blood of the 20 day group rats, the CD3+ %, CD4+ %, CD8+ % and CD4+/CD8+ were 52.91 +/- 6.27, 37.80 +/- 4.11, 14.85 +/- 3.73 and 2.72 +/- 0.82 separately. Expect CD3+ %, they all had significant differences (P < 0.05). In addition, the data of the 40 day group rats showed no diversity in statistics. In spleen, CD8+ % of the 20 day group rats was 6.23 +/- 2.87 with significant differences (P < 0.05) and IgG, IgA and IgM did not change a lot in blood serum of the high humidity groups except C3 of the 20 days group (P < 0.05).

CONCLUSIONIn high humidity environment, the immune function of the rats increased in the initial stage. As time went on, the immune function gradually went to normal level through the self adjustment.

Objective:To explore influence of thrombus aspiration combined bivalirudin during emergency PCI on my- ocardial tissue perfusion and clinical prognosis in patients with acute ST elevation myocardial infarction (STEMI). Methods:A total of 102 patients with acute STEMI,who were confirmed with thrombus burden by CAG in our hos- pital from Jan 2012 to Jun 2014,were selected.According to random number table,they were randomly divided into thrombus aspiration + bivalirudin group (n=52,thrombus aspiration group)and heparin group (n=50,routine PCI group).TIMI blood flow grade 3 rate,TIMI myocardial perfusion grade (TMPG)after PCI,ST segment re- gression rate 2h after PCI,peak value and peak time of cTnI after PCI,LVEF,LVEDd,incidence rates of bleeding and major adverse cardiovascular events (MACE)on one week and one month after PCI were compared between two groups.Results:Compared with routine PCI group,there were significant rise in postoperative TMPG grade 3 rate (56.00% vs.88.46%),TIMI grade 3 rate (58.00% vs.88.46%)and ST segment regression rate (52.00% vs. 76.92%)in thrombus aspiration group,P<0.05 or <0.01. Compared with routine PCI group one month after PCI,there was significant rise in LVEF [(53.76±5.24)% vs.(57.95±5.51)%],and significant reductions in LVEDd [(53.70±3.39)mm vs.(50.63±1.24)mm],peak value [(16.00±4.28)μg/L vs.(13.81±4.00)μg/L]and peak time [(14.00±2.80)h vs.(13.00±2.23)h]of cTnI in thrombus aspiration group,P<0.05 or <0.01. Incidence rate of mild bleeding in thrombus aspiration group was significantly lower than that of routine PCI group (1.9% vs.16.0%),P<0.05,but there was no significant difference in incidence rate of MACE between two groups,P>0.05. Conclusion:Thrombus aspiration combined bivalirudin during emergency PCI is safe and fea- sible for acute STEMI patients,it can effectively reduce incidence rate of bleeding,remove coronary thrombus,im- prove myocardial tissue perfusion and doesn't increase incidence rate of MACE.

Objective To summarize the clinical characteristics and diagnosis and treatment of hemangioma of small intestine in children.Methods Location,pathology,clinical manifestation,diagnosis and treatment of 3 cases from our hospital and 44 cases reported in our courtry with hemangioma of the small bowel were analyzed from 1994 to 2004.Results These tumors locating in jejunum,ileum,duodenum as well as parts small intestine were 31.9%,42.6%,4.2% and 21.3%,respectively.Solitary and multiple tumors were 29.8% and 70.2% separately.The histopatholical report of 10 cases revealed that capillary,cavernous,mixed type hemangioma and hematolymphangioma were 2,6,1 and 1 cases,respectively.Thirty nine children presented with recurrent black stool.Five patients manifest in the form of intussusception.One child passed a bloody stool so massive as to cause shock.Small-bowel obstruction occurred in 5 cases.The hemoglobin of 38 patients were lower than 90 g/L.The incidence of preoperative diagnosis was only 10.6%.All of patients were performed operation.Conclusions The frequent locations of hemangioma of small intestine are in ileum and jejunum,and multiple tumors are common.The diseases are characterized as recurrent hematochezia with painlessness.Preoperative diagnosis of a small bowel hemangioma can be very difficult.The segments of small bowel with hemangioma resection are the most method of the treatment.

Aim To screen peptides binding specifically to anti-human PTA1mAbs from a random twelve-peptide phage-disp-layed library. Methods Series of PTA1mAbs(LeoA1、 1B11、 C9、 2D1、 2E9、 2G8、 2H2 and E8)were purified using protein-A affinity column. PTA1mAbs which could bind PTA1-Fc fusion protein binding to its ligand were confirmed by flow cytometry, and then used as target to screen phage library. After three rounds of affinity screening, the peptide sequences of positive phage clones were determined and analyzed. Results LeoA1 could block PTA1-Fc fusion protein binding to its ligand. 13 phages which could bind specifically to LeoA1 were isolated from phage library and further confirmed by ELISA. Conserved motifs were found among the sequences of the peptides. Conclusion It was shown that the conserved motifs were candidafe regions binding to PTA1 ligand,which is important to identify functional epitopes for seeking ligand of PTA1 and further investigation of biological function of PTA1.

Radical retropubic prostatectomy (RRP) has been one of the most effective treatments for prostate cancer.This study is designed to identify the related predictive risk factors for complications in patients following RRP.Between 2000 and 2012 in Department of Urology,Fudan University Shanghai Cancer Center,421 cases undergoing RRP for localized prostate cancer by one surgeon were included in this retrospective analysis.We reviewed various risk factors that were correlated with perioperative complications,including patient characteristics [age,body mass index (BMI),co-morbidities],clinical findings (preoperative PSA level,Gleason score,clinical stage,pathological grade),and surgeon's own clinical practice.Charlson comorbidity index (CCI) was used to explain comorbidities.The total rate of perioperative complications was 23.2％ (98/421).There were 45/421 (10.7％),28/421 (6.6％),24/421 (5.7％) and 1/421 (0.2％) in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ respectively,and 323/421 (76.8％) cases had none of these complications.Statistical analysis of multiple potential risk factors revealed that BMI ＞30 (P=0.014),Charlson score ≥1 (P＜0.001) and surgical experience (P=0.0252) were predictors of perioperative complications.Age,PSA level,Gleason score,TNM stage,operation time,blood loss,and blood transfusion were not correlated with perioperative complications (P＞0.05).It was concluded that patients' own factors and surgeons' technical factors are related with an increased risk of development of perioperative complications following radical prostatectomy.Knowing these predictors can both favor risk stratification of patients undergoing RRP and help surgeons make treatment decisions.

Objective To investigate the possibility of MRI on visualizing the relationship between glossopharyngeal nerve and surrounding vessels,and to evaluate the significance of MRI in the diagnosis and treatment of glossopharyngeal neuralgia.Methods MRI findings were analyzed retrospectively in 12 patients with glossopharyngeal neuralgia,and were compared with surgical findings and effect of pain relief.Results The artery compression or contact of the glossopharyngeal entry zone,as revealed during operation in l0 patients with glossopharyngeal neuralgia,was visualized on MRI in 9 and not seen in 1.The venous compression of the glossopharyngeal entry zone was not identified on MRI in 1.The conglutinative arachnoids of the glossopharyngeal entry zone was not visualized on MRI in 1.MRI demonstrated the affected glossopharyngeal nerve root entry zone was compressed or contacted by the posterior inferior cerebellar artery (PICA)in 8 patients and by the vertebral artery in 1 patient.One patient's offending vessel was confirmed to be the anterior inferior cerebellar artery(AICA)by the operation,and the surgical findings were corresponded with MRI in others.Vascular compression or contact of the affected glossopharyngeal nerve was not visualized on MRI in 3 patients,and operation confirmed that the glossopharyngeal nerve root entry zone was compressed by unknown artery in 1,by small vein in 1,and by eonglutinative araehnoids in 1, respectively.Eight patients presented with symptoms of the ipsilateral trigeminal neuralgia concurrently.The compression of the affected trigeminal nerve root by superior cerebellar artery(SCA)was visualized on MRI in 6 patients,and operation did not reveal the source of artery compression in 1 and corresponded with MRI findings in other 5 cases.Vascular compression of affected trigeminal nerve was not visualized on MRI in 2 patients,and intraoperative inspection revealed that trigeminal nerve root was compressed by draining vein of brainstem in 1 and not compressed by any vessels in 1.All patient's neuralgia resolved after microvascular decompression of glossopharyngeal nerve and trigeminal nerve.Conclusion It is possible to visualize the glossopharyngeal and surrounding arteries on MRI,and it is of great significance in the diagnosis and treatment of this kind of glossopharyngeal neuralgia.

The capsid protein (VP60) gene of RHDV was subcloned into the Pichia expressin vector pPICZ B to express the VP60 protein intracellularly. The recombinant plasmid was initially transformed into a E. coli strain TOP10 F'. After verification of the construct by sequencing, the recombinant plasmid was linearized by Sac I in the 5' AOX1 region and then transformed into Pichia pastoris strain GS115 using the Pichia EasyComp Kit. After selecting and verifing for the insertion of VP60 gene in the genome, two clones of Pichia transformants were select for expression test. The recombinant clones were first inoculate with BMGY in baffled flask at 28-30 degrees C in a shaking incubator (250-300 r/min) until culture reaches an OD600 = 2-6, then resuspend the cell pellet to an OD6oo of 1.0 in BMMY medium to induce expression for 5 days by methanol at a concentration of 0.5% in a 1 liter baffled flask covered with 2 layers of sterile gauze. Collect the cell pellets and break it by acid-washed 0.5 mm glass beads. The expression of recombinant Pichia strains was detected by SDS-PAGE and Western analysis with a polyclonal serum which showed a specific protein band of 60kD. Theses results indicates that the recombinant VP60 produced in Pichia was antigenically similar to the viral polypeptide. Electron microscopic observation of the recombinant Pichia-derived protein revealed the presence of virus-like particles similar in size and appearance to native virus capsids. In the haemagglutination test, the recombinant VLPs, like the native RHDV, also agglutinated human blood type O erythrocytes and could be inhibited by the anti-RHDV polyclonal serum.
