OBJECTIVE:To study endothelial NO-dependent vasodilation effect of the extracts of Herba Siegesbeckiae. METHODS:SD rat thoracic aorta rings were used to observe contraction of blood vessel, and the effects of the extracts of Herba Siegesbeckiae on the contraction induced by phenylphrine (PE). RESULTS:The extract of Herba Siegesbeckiae could inhibit the contraction of blood vessel induced by PE. After pretreatment of blood vessel by L-NNA, vasodilation effect of the extracts of Herba Siegesbeckiae was significantly attenuated at low concentration condition(P

Conclusion Monitoring should be strengthened in order to reduce or avoid the vaginal dilator adverse events.

Objective:To study the anti-tumor effects by vaccination of mice with murine melanoma B16 cells expressing calreticulin (CRT) and Human papillomavirus 16 E2 fusion protein.Methods:Mice were inoculated with B16 cells expressing CRT,E2,or CRT-E2 by intraperitoneal injection. The inoculation was repeated after one week. The activity of CTLs and NK cells,the proliferation of T cells and the amount of IFN-? secreted by spleen lymphocytes were analysed.Results:The activity of CTLs and NK cells,and the amount of IFN-? secreted by spleen lmyphocytes from mice vaccinated with CRT-E2 fusion protein were significantly higher than those of the other groups(P

Objective To study the blood pressure and cardiovascular conditions in kidney transplant recipients in order to prevent the cardiovascular complications in such patients. Methods The blood pressure and ECG were monitored day and night by noninvasive means for 86 patients after transplantation.The results were analysed and compared with the pretransplantation studies. Results Hypertension occurred in 55 out of 86 patients.There was a significant difference of average blood pressure and the occurrence of abnormal ST segment or T wave between day and night whereas no significant change was observed in blood CsA concentration,blood creatinine,serum cholesterol,blood sugar,triglyceride and K+,N+,Cl-,TCO 2,Ca 2+ ,etc. Conclusions Cardiovascular complications in kidney transplant recipients is related to the high blood pressure during night,the normal day-night blood pressure rhythm being violated.It is not related to the immunosuppresives used.

Objective To evaluate the use of isoptin in kidney transplants recipients. Methods The graft acute rejection rate,the cyclosporin A daily dose and its trough level and toxicity,the blood pressure and cardiovascular complications,the serum creatinine and blood sugar were studied in cadaveric kidney transplant recipients both with and without the additional use of isoptin. Results With the additional use of isoptin in 44 cadaveric kidney transplant recipients,the acute rejection rate has not increased.After using isoptin for 2 weeks,CsA blood level has been increased 25.5% whereas the CsA dose been cut down 32.6 %.So,drug expense dropped about 30.0% and CsA toxicity (hand tremble,insomnia) was slightly decreased. Conclusions Isoptin does not inecease the graft acute rejection rate yet makes the CsA dose and its toxicity less.

OBJECTIVETo investigate the risk factors of vaginal dilators by 567 adverse event reports, and to provide a reference for the reasonable use.

METHODSWith retrospective case study, analyzed 567 reports induced by vaginal dilators by National Adverse Drug Reaction Monitoring Center in 2012.

RESULTSExpected treatment of disease might be relevant with severity of adverse events, while age was not the related factor; the influencing factor of consequences of grading was the classification of the cause of adverse events.

CONCLUSIONMonitoring should be strengthen in order to reduce or avoid the vaginal dilator adverse events.

Aerenchyrna formation has been described in depth in a number of species at a histological level. But large gaps remain in our understanding of its regulation as a developmental process. It is attempted to analyse essential mineral elements like K, Mg, Cu, Zn, Ca and P in the cell wall of aerenchyma cells in petioles ofS. trifolia at five different developmental stages by CSEM-EDX technique. At early stage, K and Cl concentrations in cell wall were high up to 36% and 4.3% of dry weight, respectively. It supported the hypotheses that aerenchyma spaces are filled with liquid at early developmental stages of aerenchyma in S. trifolia petiole. Mg concentration was high at stage 2, up to 0.86% of dry weight. Zinc and Cu were detected only at rapid expansion stages, during which the concentrations were up to 1.5% and 2.5%, respectively. Calcium was detected in the cell wall only at mature stages, the concentration was high up to 1.3% of dry weight at stages 4 and 5. These results confirmed that the element concentration of aerenehyma cell wall undergoes dynamic changes during different developmental stages, and a low Ca with high Zn and Cu concentration are needed for cell expansion. Copper and Zn deposition in the cell wall showed a significant positive linear correlation, suggesting that these two elements share same or similar uptake and transport mechanism in plants.

Objective To investigate the effect of the new polyamine analogue tetrabutyl propanediamine (TBP) on cell proliferation and the underlying mechanism. Methods MTT assay was performed to determine cell proliferation. Flow cytometry was performed to detect cell cycle transition. DNA fragmentation and mitochondrial membrane potential determinations were performed to detect cell apoptosis. The activity of key enzymes in polyamine catabolism was detected by chemiluminescence assay. Results TBP could significantly inhibit the proliferation of HL-60 cells by blockingcell cycle transition and by inducing apoptosis. The TBP-induced apoptosis of HL-60 cells was in a dose-dependent manner. The enzyme activities of SMO and APAO were also significantly increased in HL-60 cells after treatment with 100 μM TBP for 24 hours. Conclusions TBP, as a new putrescine analogue, could inhibit proliferation of HL-60 cells by increasing the enzyme activity of SMO and APAO and inducing apoptosis.

Objective To investigate the effect of S-1 on serum thymidine kinase-1 ( TK1 ) , vascular endothelial growth factor ( VEGF ) and insulin-like growth factor-1 (IGF-1) and tumor biomarkers, estrgen levels and quality of life in patients with advanced breast cancer.Methods 69 cases with advanced breast cancer from January 2014 to May 2015 in the hospital were selected and randomly divided into two groups.34 cases in control group were treated by conventional therapy, and 34 cases in experimental group were treated with S-1.Serum TK1, VEGF and IGF-1, tumor biomarkers, estrogen level and quality of life score were compared pre-and post-treatment.ResuIts Compared with control group, the levels of VEGF, IGF-1 and TK1 were lower (P<0.05), serum CA125, CEA and CA15-3 concentrations were lower (P<0.05),the LH, E2 and E1 levels were lower (P<0.05) and the survival quality score was higher in experimental group ( P<0.05 ) .ConcIusion S-1 has better clinical curative effect in treatment of patients with advanced breast cancer, and effectively reduce serum TK1, VEGF, IGF-1, tumor biomarker levels, improve the quality of survival, which has important significance.
