Objective To investigate the effects of soluble CD40 ligand combined with LY294002,a specific inhibitor of phosphatidylinositol 3-kinase,on proliferation and invasion of gastric cancer cells (AGS ) and its potential mechanisms. Methods The effect of gradient concentration of sCD40L and its combination with LY294002 on cellular proliferation was determined using MTT assay. The ability of cellular invasion and migration was evaluated by wound healing and Transwell invasion assay. The protein expression of PI3K, p-Akt and vascular endothelia growth factor (VEGF) was tested by Western blotting. Results The inhibitory effect of cellular proliferation in sCD40L, LY294002 and sCD40L + LY294002 groups was 70. 1%, 65. 7% and 41. 3%, respectively, with significant difference (P<0. 05). And wound healing was also delayed in cells treated with sCD40L plus LY294002 when compared with those treated with sCD40L or LY294002. These results indicated that the inhibitory effect of cellular proliferation, migration and invasion was enhanced when cells were treated with sCD40L plus LY294002. The protein expression of PI3K,p-Akt and VEGF increased in cells treated with sCD40L, but reduced drastically in cells treated with sCD40L plus LY294002. Conclusion Inhibiting PI3K/Akt signaling pathway may enhance the inhibitory effect of proliferation, migration and invasion by sCD40L on AGS cells, which provide a new way for biochemical therapy of gastric cancer.

Result Sixteen ASOPP patients successfully recovered after hospital discharge and another two died from multiple organ function failure because of excessive pesticides. Conclusions Effective observation and nursing care of airways based on their characteristics in ASOPP patients including prevention of unexpected shedding , appropriate humidity of airways and prevention of infection of ventilator-associated pneumonia(VAP). All of these measures can reduce complications and contribute to the early recovery of patients.

Objective To determine the correlation between aquaporin-4 antibody (AQP4-Ab) and optic neuropathy in patients with neuromyelitis optica spectrum disorder (NMOSD).Methods The clinical and biochemical data of 53 patients with NMOSD diagnosis based on AQP4-Ab level in Changhai Hospital between January 2010 and October 2015 were retrospectively analyzed.According to optic neuropathy occurrence,the NMOSD patients were divided into optic neuropathy and non-optic neuropathy groups.Clinical and biochemical characteristics were compared between the two groups.According to the serum AQP4-Ab levels,the NMOSD patients were divided into AQP4-Ab seropositive and seronegative groups.The incidence of optic neuropathy was compared between the two groups.The correlation between optic neuropathy and AQP4-Ab levels was analyzed.Results Between the optic neuropathy and non-optic neuropathy groups,no significant differences in sex,age at onset,disease course,serum alanine aminotransferase levels,protein levels in cerebral spinal fluid,IgG index,and oligoclonal band were observed (P ＞ 0.05).However,statistically significant differences were found in frequency,superficial sensory impairment,serum creatinine level,and serum AQP4-Ab level (P ＜ 0.05).Between the AQP4-Ab sempositive and semnegative groups,a statistically significant difference in the incidence of optic neuropathy was observed (F =4.93,P ＜ 0.05).The incidence of optic neuropathy positively correlated with AQP4-Ab levels (r =0.297,P ＜ 0.05).Conclusion NMOSD patients with AQP4-Ab seropositivity could be prone to optic neuropathy,and the correlation may be beneficial to early diagnosis,therapy,and monitoring of NMOSD.

Objective To investigate the relationship between the peak value of contrast media reaching abdominal aorta andpatients’ factors.Methods Ominpaque 300 mgI/ml 20 ml was injected at a rate of 2.5 ml/s in 108 patients and after 12 s was tracked by test bolus in the abdominal aorta at the level of celiac trunk, then the peak value in the abdominal aorta was achieved by the software dynamic evaluation. Regression analysis and stepwise regression analysis were used to study how the peak value of contrast media reaching abdominal aorta influenced by the patients’ factors including patients’ gender, age, height, weight, heart rate, blood pressure, injection site, peak time, and whether being with heart disease , diabetes mellitus or chemo . Results The peak value of contrast media reaching abdominal aorta was lower in male than that in female averagely, decreased gradually as the patients’ height, weight and peak time increased. The peak value of the injection site in the vein of hand back was lower than that of the cubitus generally and it was not influenced by the patients’ heart rate, blood pressure or whether being with heart disease, diabetes mellitus or chemo. Recommended formula of peak value(HU)=383.8400-Height(cm)?1.0909-Weight(kg)?0.6760+injection site?16.7878-peak time(s)?1.6882.Conclusion The volume of contrast media used in patients needing exam of CT angiography can be adjusted according to the patients’ age, gender, height, weight, injection site and peak time.

Objective To study the effect of combining recombinet interferon α -2b gel and loop electrosurgical excision procedure (LEEP) to treat cervical intraepithehal neoplasia (CIN). Methods Prospective, randomly and control study was progressed in 80 patients with CIN Ⅱ-Ⅲ. Before carrying out LEEP, all women were performed high-risk HPV DNA detection by the method of HC2. Among them, forty women were. assigned to be the study group, in which the patients were added to use recombinet interferon α -2b gel for three courses of treatment before and after LEEP, the other forty women who carried out LEEP simply were assigned to be the control group. All patients were examined by hquid-based thinprep cytology test (TCT) and colposcopic site-specific biopsies to doubtful focus of infection in the 3rd, 6th, 9th and 12th month after treatment, and judged the effect by using HC2 in the 6th and 12th month after treatment. Results Eighty patients were not detected residue and recidivafion of CIN diagnosed by coiposcopic site-specific biopsies to doubtful focus of infection. In the study group, 3 women were abnormal detected by TCT, 37 women were negative detected by HC2, the negative rate was 92.5% when LEEP ended 6 months. The cure rate was 100.0% when LEEP ended 12 months. In the control group, 21 women were abnormal detected by TCT, 19 women were negative detected by HC2, the negative rate was 47.5% when LEEP ended 6 months, 8 women were negative detected by TCT, 25 women were negative detected by HC2, the cure rate was 62.5% when LEEP ended 12 months.In the 6th and 12th month after LEEP, the difference was distinguished in the cure rate between two groups. Conclusions There is double interrupted effects by combining recombinets interferon α -2b gel and LEEP to treat CIN. It can raise the one-time cure rate of the patients with CIN.

OBJECTIVETo discuss the drug intervention in diversity changes of TCRVbeta gene in AIDS patients with incomplete immune reconstitution.

METHODPBMCs were isolated from 37 cases of AIDS patients failure to immune reconstitution before and after treatment with Immune 2 and 15 cases of HIV negative healthy donors. The human gene TCRVbeta CDR3 diversity quantitative detection reagent box were used, and mapped the distribution of gene scanning and calculated different CDR3 fragme of each Vbeta family size.

RESULT(1) Gaussian distribution of TCRVbeta families in patients with incomplete immune reconstitution after one year of HAART, had been broken with the occurrence of the offset TCR lineage. After six months of treatment of traditional Chinese medicine combined HAART, the TCR lineage has been partially restored. (2) Evaluated by the D (distance) value calculated by a quantitative analysis software which the kit provides, there were no significant difference in D value change between the two groups, but with traditional Chinese medicine can reduce the data variability. (3) CD4+ T cell counts had a significant correlation (r = -0.772, P = 0.000) with TCRVbeta genetic diversity.

CONCLUSIONStudy of the mechanism showed oligoclonal of TCRVbeta family can get recovery in some degrees after treated by Immune 2 plus HAART, suggesting that the medicine may promote T-cell receptor gene rearrangement, helping immune cells to effectively identify the virus to reduce T-cell apoptosis.
